Intraocular pressure changes under an atmospheric pressure spectrum in a multiplace hyperbaric chamber / Análise de alterações da pressão intraocular (PIO) sob o espectro da pressão atmosférica em uma câmara hiperbárica multi-lugar

ABSTRACT Purpose: To evaluate the influence of atmospheric pressure changes on the behavior of intraocular pressure of healthy military individuals-students and instructors of the National Navy's Diving & Rescue School at the "ARC BOLÍVAR" naval base-during a simulated immersion in the hyperbaric chamber of the Naval Hospital of Cartagena. Methods: A descriptive exploratory study was performed. The intraocular pressure was measured at different atmospheric pressures during 60-min sessions in the hyperbaric chamber while breathing compressed air. The maximum simulated depth was 60 feet. Participants were students and instructors of the Naval Base's Diving and Rescue Department. Results: A total of 48 eyes from 24 divers were studied, of which 22 (91.7%) were male. The mean age of the participants was 30.6 (SD=5.5) years, ranging from 23 to 40. No participant had a history of glaucoma or ocular hypertension. The mean base intraocular pressure at sea level was 14 mmHg, which decreased to 13.1 mmHg (decreased by 1.2 mmHg) at 60 feet deep (p=0.0012). However, during the safety stop at 30 feet, the mean IOP kept decreasing until reaching 11.9 mmHg (p<0.001). By the end of the session, the mean intraocular pressure reached 13.1 mmHg, which is inferior and statistically significant when compared with the intraocular pressure base mean (p=0.012). Conclusions: In healthy individuals, the intraocular pressure decreases when reaching a depth of 60 feet (2.8 absolute atmosphere pressure) and it decreases even more during ascension at 30 feet. Measurements at both points were significantly different when compared with base intraocular pressure. The final intraocular pressure was lower than the baseline intraocular pressure, suggesting a residual and prolonged effect of the atmospheric pressure on intraocular pressure.

RESUMO Objetivo: Avaliar a influência das alterações da pressão atmosférica no comportamento da pressão intraocular de indivíduos militares saudáveis-alunos e instrutores da Escola de Mergulho e Resgate da Marinha Nacional na base naval "ARC BOLÍVAR"-durante uma imersão simulada na câmara hiperbárica do Hospital da Marinha de Cartagena. Métodos: Realizamos um estudo exploratório descritivo. A pressão intraocular foi medida em diferentes pressões atmosféricas durante sessões de 60 minutos na câmara hiperbárica respirando ar comprimido. A profundidade máxima simulada foi de 60 pés. Os participantes eram alunos e instrutores do Departamento de Mergulho e Resgate da Base Naval. Resultados: Quarenta e oito olhos de 24 mergulhadores foram estudados. Vinte e dois participantes (91,7%) eram do sexo masculino. A média de idade dos participantes foi de 30,6 (DP=5,5) anos, variando de 23 a 40. Nenhum participante tinha histórico de glaucoma ou hipertensão ocular. A média de base da pressão intraocular ao nível do mar foi de 14 mmHg, diminuindo para 13,1 mmHg (queda de 1,2 mmHg) a 60 pés de profundidade (p=0,0012). Entretanto, durante a parada de segurança a 30 pés, a pressão intraocular média continuou diminuindo até atingir 11,9 mmHg (p<0,001). Ao final da sessão, a pressão intraocular média atingiu 13,1 mmHg, valor inferior e estatisticamente significativo quando comparada à média de base da pressão intraocular (p=0,012). Conclusões: Em indivíduos saudáveis, a pressão intraocular diminui ao atingir uma profundidade de 60 pés (2,8 de pressão atmosférica absoluta) e diminui ainda mais durante a ascensão a 30 pés. As medidas em ambos os pontos foram significativamente diferentes quando comparadas à pressão intraocular de base. A pressão intraocular final foi menor do que a pressão intraocular de base, sugerindo um efeito residual e prolongado da pressão atmosférica sobre a pressão intraocular.

The Brazilian army and the low prevalence of sexually transmitted infections in women of the military garrison of Campinas between 2017 to 2020: a prospective, cross-sectional epidemiological study

ABSTRACT BACKGROUND: Given the characteristics of military missions, intense interpersonal contact, and wide variation in casual relationships, the military has long been recognized as a high-risk population for sexually transmitted infections (STIs). OBJECTIVE: To assess the prevalence of STIs and socioepidemiological profile of women in the military garrison of Campinas. DESIGN AND SETTING: This prospective, cross-sectional epidemiological study, assisted by the Health Fund in the military garrison of Campinas, assessed the prevalence of human immunodeficiency virus (HIV), hepatitis B and C, syphilis, human papillomavirus (HPV), chlamydia, and gonococcus in military women or companions of soldiers with active or previously active sexual life. METHODS: This study included 647 women based on the non-inclusion criteria. They underwent clinical and laboratory tests for diagnosis of STIs. For statistical analysis, patients were divided into groups according to the presence or absence of STIs and into age groups. RESULTS: Most women were military dependents, and the majority were asymptomatic. The prevalence of STIs, in ascending order, was 0.3% for hepatitis B and C, 0.62% for syphilis, 0.62% for gonorrhea, 1.08% for chlamydia, and 2.63% for HPV. There were no cases of HIV infection. CONCLUSIONS: The Brazilian Army has the most women-like dependents in the military, belonging to the hierarchical circle of the squares. Early onset of sexual activity favored STIs approximately twice, and younger women had approximately seven times more chlamydia infections. In the general population studied, the prevalence of STIs was lower than expected than in the armed forces of other nations.

Nível de atividade física, capacidade funcional e flexibilidade de soldados ingressantes no Exército brasileiro / Level of physical activity, functional capacity and flexibility of soldiers entering the Brazilian Army

Objetivou avaliar o nível de atividade física, capacidade funcional (CF) e a flexibilidade de adultos jovens antes e após dez meses de ingresso em um programa de exercícios físicos no Exército brasileiro. Trata-se de uma pesquisa de coorte prospectivo. O nível de atividade física foi avaliado pelo Questionário Internacional de Atividade Física (IPAQ), a CF, pelo Teste de Cooper, e a flexibilidade, pelo Banco de Wells. Amostra (n = 198; 18±0,27 anos) com índice de massa corporal (IMC) de 23,23±3,84 kg/m2. Após dez meses de admissão no Exército, constatou-se redução na prevalência de sedentarismo (33  28%) e na CF (2.982±243,61  3.117±192,87 m), sem alteração da flexibilidade (27,31±7,39  27,52±7,40 cm). Houve grande tamanho de efeito no IMC, na relação cintura quadril (RCQ) e na flexibilidade. Conclui-se que a inserção em um programa de exercícios físicos no Exército brasileiro aumentou a CF e reduziu a RCQ dos jovens.

This study aimed to evaluate the level of physical activity, functional capacity (FC), and flexibility of young adults before and ten months after joining a physical exercise program in the Brazilian Army. This was a prospective cohort study. The level of physical activity was assessed using the International Physical Activity Questionnaire (IPAQ), FC using the Cooper Test, and flexibility using the Wells bench. Sample (n = 198; 18±0.27 years) with a body mass index (BMI) of 23.23±3.84 kg/m2. After ten months of admission to the Brazilian Army, there was a reduction in the prevalence of sedentary lifestyle (33  28%) and FC (2,982±243.61  3,117±192.87 m), without change in flexibility (27.31±7.39  27.52±7.40 cm). There was a large effect size on BMI, waist-hip ratio (WHR), and flexibility. In short, inclusion in a physical exercise program in the Brazilian Army increased FC and reduced the WHR of young recruits.

Creative self-beliefs of civilian and military school students / Crenças do self criativo de estudantes de escolas civis e militares / Creencias del self creativo de estudiantes de escuelas civiles y militares

Creative Self-Efficacy (CSE) and Creative Personal Identity (CPI) are creative self-beliefs which act as creative achievement predictors in different contexts, including school. Brazilian theoretical studies suggest that characteristics of military school can inhibit creative expression. The question is raised whether the school environment can influence CSE and CPI. Therefore, the goal was to compare male and female students from military and civilian schools, in terms of CSE and IPC, in addition to verifying the interaction between the variables. Participants were 230 secondary school students, with a mean age of 16.07 years (SD = .92). The Short Scale of Creative Self (SSCS) and a sociodemographic questionnaire were used. No significant differences or interactions were observed, except for the higher IPC in women when compared to men. Thus, it is possible that the typical restrictions of the military model of education do not necessarily imply barriers to creativity.(AU)

Autoeficácia Criativa (AEC) e Identidade Pessoal Criativa (IPC) são crenças do self criativo que atuam como preditoras da realização criativa em diversos contextos, inclusive escolar. Estudos teóricos brasileiros sugerem que as características da escola militar podem inibir a expressão criativa. Questiona-se como AEC e IPC podem ser influenciadas pelo ambiente escolar. Portanto, o objetivo deste estudo foi comparar estudantes de escolas militares e civis, do sexo masculino e feminino, quanto à AEC e IPC, além de verificar possível interação entre as variáveis. Participaram 230 estudantes do ensino médio, com idade média de 16,07 anos (DP = 0,92). Utilizou-se a Escala Breve do Self Criativo (EBSC) e um questionário sociodemográfico. Não foram observadas diferenças ou interações significativas entre os grupos, exceto pela IPC superior nas mulheres, quando comparadas aos homens. Nesse sentido, é possível que as restrições típicas do modelo militar de educação não impliquem necessariamente barreiras à criatividade.(AU)

La Autoeficacia Creativa (AEC) y la Identidad Personal Creativa (IPC) son creencias del self creativo que actúan como predictores del logro creativo en diferentes contextos, incluyendo el escolar. Estudios teóricos brasileños sugieren que las características de las escuelas militares pueden inhibir la expresión creativa. Se cuestiona si el entorno escolar puede influir en la AEC y la IPC. Por lo tanto, el objetivo de este estudio fue comparar alumnos y alumnas de escuelas militares y civiles, en términos de AEC y IPC, además de verificar la interacción entre las variables. Participaron 230 estudiantes de secundaria de escuelas públicas, con una edad promedia de 16,07 años (DS = 0,92). Se utilizó la escala Short Scale of Creative Self (SSCS) y un cuestionario sociodemográfico. No se observaron diferencias o interacciones significativas entre los grupos, excepto por una IPC superior en mujeres en comparación con los hombres. Es posible que las restricciones típicas del modelo educativo militar no necesariamente impliquen barreras para la creatividad.(AU)

Estresse ocupacional e enfrentamento em enfermeiros de um Hospital do Exército Brasileiro: abordagem qualitativa / Occupational stress and coping among nurses at a Brazilian Army Hospital: a qualitative approach

Este estudo buscou compreender os estressores ocupacionais percebidos por enfermeiras militares e os seus modos de enfrentamento. Pesquisa de abordagem qualitativa, realizada em um hospital do Exército Brasileiro. A coleta de dados ocorreu de agosto a outubro de 2019 por meio de entrevista com uso de gravador eletrônico. Os dados foram analisados de forma descritiva, e utilizou-se como referencial o Método Hermenêutico-Dialético com fundamentação na teoria dos sistemas de Betty Neuman. Com base nas unidades de significação dos discursos das participantes, foram identificadas três categorias de análise: (1) Estressores ocupacionais percebidos; (2) Percepção das enfermeiras sobre as repercussões do ambiente de trabalho na vida cotidiana; e (3) Enfrentamento dos estressores ocupacionais. A percepção das enfermeiras militares sobre o estresse ocupacional evidenciou que esse cenário é constituído de estressores típicos da profissão, do ser enfermeiro e do ser militar, podendo haver respostas diversas ao enfrentamento do estresse percebido.

This study aimed to understand the occupational stressors perceived by military nurses and their ways of coping. A qualitative research was carried out at a Brazilian Army hospital. Data collection took place from August to October 2019 through an interview by using an electronic recorder. The data were analyzed in a descriptive way, and the hermeneutic-dialectical method was used as a reference based on Betty Neuman's systems theory. Based on the units of signification of the participants' discourses, three categories of analysis were identified: (1)Perceived occupational stressors; (2) Perception of nurses about the repercussions of their work environment in everyday life; and (3) Coping with occupational stressors. The military nurses' perception of occupational stress showed that this scenario consists of stressors typical of the profession, of what it is like to be a nurse and to be in the military. There may be several responses to coping with perceived stress.

Honores a Sir Ernest Shackleton en Sanidad Militar / Honors to Sir Ernest Shackleton in Military Health / Honras a Sir Ernest Shackleton em Saúde Militar

Ernest Shackleton ha sido en la historia, un personaje que dejó huella como ejemplo de resiliencia y liderazgo. En 1914 realizó como jefe de expedición su segundo viaje antártico, frustrado por el hundimiento de su buque insignia. La operación de rescate del grueso de la tripulación varada en el continente más meridional lo llevó a recalar en Montevideo. Desde este puerto partió el buque Instituto de Pesca N°1, con tripulación de Uruguay y Shackleton incluido, no logrando completar el salvamento. De esta acción nació el aprecio hacia la persona del explorador por parte del gobierno de la República. En su postrer travesía, ya fallecido llegó a las Islas Georgia del Sur y a su cuerpo se le realizó un proceso de conservación para ser traído a nuestro país y continuar viaje al puerto de origen en Inglaterra. Es en esa circunstancia que el gobierno del doctor Baltasar Brum solicitó a la Comisión Permanente del Parlamento, se le rindieran honores fúnebres de Ministro de Estado. El embalsamado del cuerpo fue realizado el 30 de enero de 1922, por parte de personal médico y técnico del Hospital Militar, así como los honores que le rindieron por el Servicio de Sanidad del Ejército y la Armada.

Ernest Shackleton has been in history, a character who left his mark as an example of resilience and leadership. In 1914, as expedition leader, he made his second Antarctic voyage, frustrated by the sinking of his flagship. The operation to rescue the bulk of the crew stranded on the southernmost continent led him to Montevideo. The Instituto de Pesca N°1, with Uruguayan crew and Shackleton included, departed from this port, but was unable to complete the rescue. From this action was born the appreciation of the explorer by the government of the Republic. In his last voyage, when he died, he reached the South Georgia Islands and his body underwent a preservation process to be brought to our country and continue his voyage to the port of origin in England. It is in this circumstance that the government of Dr. Baltasar Brum requested the Permanent Commission of the Parliament to pay him the funeral honors of a Minister of State. The embalming of the body was carried out on January 30, 1922, by medical and technical personnel of the Military Hospital, as well as the honors rendered by the Army and Navy Health Service.

Ernest Shackleton deixou sua marca na história como um exemplo de resiliência e liderança. Em 1914, ele fez sua segunda viagem à Antártica como líder da expedição, frustrado pelo naufrágio de seu navio principal. A operação para resgatar a maior parte da tripulação encalhada no continente mais ao sul o levou a Montevidéu. O Instituto de Pesca N°1, com tripulação do Uruguai e Shackleton incluído, partiu desse porto, mas não conseguiu concluir o resgate. Essa ação deu origem ao reconhecimento do explorador pelo governo da República. Em sua última viagem, quando morreu, chegou às Ilhas Geórgia do Sul e seu corpo foi preservado para que pudesse ser trazido ao nosso país e continuar sua viagem até o porto de origem na Inglaterra. Foi nessa circunstância que o governo do Dr. Baltasar Brum solicitou ao Comitê Permanente do Parlamento que lhe prestasse as honras fúnebres de um Ministro de Estado. O embalsamamento do corpo foi realizado em 30 de janeiro de 1922, pela equipe médica e técnica do Hospital Militar, bem como as honras prestadas a ele pelo Serviço de Saúde do Exército e da Marinha.

La Defensa Pasiva y su división médica de emergencia / Passive Defense and its emergency medical division / Passive Defence e sua divisão médica de emergência

Durante la Segunda Guerra Mundial el gobierno de Uruguay intentó prepararse para una eventual defensa militar del territorio y la defensa de la población civil en caso de sufrir ataques aéreos. La Defensa Pasiva, fue la estructura gubernamental que junto a la voluntad en todas las clases sociales, funcionó en todo el territorio nacional con la finalidad de proteger a la población civil de los ataques aéreos y guerra química, generando un espíritu de solidaridad a través de su División Médica de Emergencia.

During the Second World War, the government of Uruguay tried to prepare for an eventual military defense of the territory and the defense of the civilian population in case of air raids. The Passive Defense was the governmental structure that, together with the will of every social class, operated throughout the national territory with the purpose of protecting the civilian population from air raids and chemical weapons, generating a spirit of solidarity through its Emergency Medical Division.

Durante a Segunda Guerra Mundial, o governo uruguaio tentou se preparar para uma eventual defesa militar do território e para a defesa da população civil em caso de ataques aéreos. A Defesa Passiva era a estrutura governamental que, juntamente com a vontade de todas as classes sociais, operava em todo o território nacional com o objetivo de proteger a população civil de ataques aéreos e da guerra química, gerando um espírito de solidariedade por meio de sua Divisão Médica de Emergência.

Prevalência e Autoconhecimento de Indicadores de Inflamação Sugestivos de Doença Periodontal em Militares / Prevalence And Self-Knowledge Of Indicators Of Inflammation Suggestive of Periodontal Disease In Military Personne

O objetivo deste estudo foi identificar a prevalência e o autoconhecimento para indicadores de inflamação sugestivos de doença periodontal em militares de ambos os sexos. Os militares foram recrutados para realização de um censo odontológico para toda a população do Centro de Instrução Almirante Wandenkolk (CIAW) da Marinha do Brasil, totalizando 409 voluntários. Foram formados dois grupos para posterior análise: Grupo 1- contendo exclusivamente mulheres e Grupo 2- contendo exclusivamente homens. Foram realizados 409 exames clínicos e analisados 409 questionários. Os resultados demonstraram que, quanto aos participantes militares, 40,1% foram do sexo feminino e 59,9%, do sexo masculino; 87% faziam uso do fio dental, desses 56% usavam diariamente; 77% apresentaram frequência de escovação de três vezes ao dia ou mais; 74,3% relataram que visitam regularmente o dentista, e a proporção de mulheres que frequenta regularmente o dentista superou significativamente a proporção de homens que o fizeram (I.C. 95%; p < 0,001); 61,6% afirmaram conhecer a doença periodontal. A avaliação profissional verificou a presença de indicadores de inflamação sugestivos de doença periodontal em 45,2% participantes, desses 37% eram do gênero feminino e 63%, do gênero masculino, não sendo observada diferença estatística entre os gêneros (I.C. 95%; p = 0,2248). Concluiu-se que a prevalência de indicadores de inflamação sugestivos de doença periodontal encontrada foi de 45,2%; o autoconhecimento dos militares sobre doença periodontal foi baixo, apenas 19%; dessa forma foi verificada diferença estatística entre o conhecimento das mulheres e dos homens; e observou-se que a maioria dos participantes estava dentro da frequência correta para consulta de retorno ao dentista.

The objective of this study was to identify the prevalence and self-recognition for indicators of inflammation suggestive of periodontal disease in military personnel of both genders. The military personnel was recruited to conduct a dental census for the entire population of the Admiral Wandenkolk Training Center of the Brazilian Navy, totaling 409 volunteers. Two groups were formed for further analysis: Group 1- containing exclusively women and Group 2- containing exclusively men. A total of 409 clinical examinations were performed and the questionnaires were analyzed. The results showed that, regarding the military participants, 40.1% were female and 59.9% were male; 87% used dental floss, of which 56% used it daily; 77% brushed three times a day or more; 74.3% reported that they visited the dentist regularly, and the proportion of women who regularly visited the dentist significantly exceeded the proportion of men who did (C.I. 95%; p<0.001); 61.6% said they knew about periodontal disease. The professional evaluation verified the presence of inflammation indicators suggestive of periodontal disease in 45.2% of the participants, of which 37% were female and 63% were male, with no statistical difference between genders (95% CI, p=0.2248). The prevalence of inflammation indicators suggestive of periodontal disease was 45.2%; the self-knowledge of the military about the periodontal disease was low, only 19%; thus a statistical difference was found between the knowledge of females and males; and it was observed that most participants were within the correct frequency for return visits to the dentist.

Evaluation of applicants unable to perform military service due to eye disease in terms of disease etiology and preventability: A cross-sectional study

Purpose: Our study’s goal was to investigate the individuals who took a pre?military examination and were pronounced “unfit for military service,” in terms of etiological grouping, legal blindness, and whether or not the illness could have been prevented. Methods: The files of 174 individuals deemed “unfit for military service” due to eye disease at the State Hospital Ophthalmology Department between January 2018 and January 2022 were retrospectively evaluated. The disorders were classified as refractive error, strabismus, amblyopia?related, congenital, hereditary, infectious/inflammatory, degenerative, and trauma?related pathologies. The reasons for unsuitability for military service were classified according to monocular and binocular legal blindness, preventability, and treatability with early diagnosis. Results: In our study, the reasons associated with refractive error, strabismus, and amblyopia were placed first in the etiology of unsuitability for military service (40.2%). The next most prevalent condition was trauma (19.5%), which was followed by degenerative (18.4%), congenital (10.9%), hereditary (6.9%), and infectious/inflammatory disorders (4.0%). There was a history of penetrating trauma in 79.4% of trauma patients and blunt trauma in 20.6% of patients. When the etiology was evaluated, 19.5% were in preventable and 51.2% were in treatable group with early diagnosis. In our study, legal blindness was detected in 116 patients. Of these patients, 79% had monocular legal blindness and 21% had binocular legal blindness. Conclusion: It is vital to investigate the etiology of visual disorders, control preventable causes, and determine the methods that will provide early diagnosis and treatment of curable causes.

Leva militar y violencia en contra de la juventud en el Perú

(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.

(analítico) O serviço militar obrigatório no Peru gerou debates e controvérsias devido à violência com que opera, tanto forçando e maltratando e até torturando jovens sequestrados. Somente no final da década de 1990 seria demonstrada a crueldade com que foi operada, desmantelando-a no ano de 2000. O artigo busca identificar essa violência por meio da canalização que operaria durante a década de 1960. Metodologicamente, um total de 28 entrevistas aplicam-se com homens e mulheres entre 60 e 83 anos. Como hipótese, propõe-se o uso da discriminação e do autoritarismo para degradar os setores mais populares do país. Assim, as estratégias biopolíticas aviltantes instaladas persuadiriam a população da necessidade de tais cobranças militares, incorrendo em um homicídio juvenil legalizado.

Descripción de la composición corporal en una cohorte de oficiales activos en el Ejército de Colombia

La composición corporal en población militar es indispensable en la caracterización del estado nutricional, lo cual representa la acumulación de grasa, huesos, agua y músculo total en el cuerpo. Objetivo: Describir y analizar variables de la composición corporal en datos recolectados de una muestra de oficiales del Ejército Nacional de Colombia. Metodología: Estudio descriptivo entre oficiales con la finalidad determinar la composición corporal y bioimpedancia con el estado nutricional como un indicador de riesgos sobre la salud, utilizando un tallímetro, báscula con precisión de 100 gramos, cinta antropométrica flexible, compás de pequeños diámetros y de pliegues cutáneos. Se consideró un valor de p estadísticamente significativo <0,05. Resultados: La muestra de oficiales recolectada está compuesta por un total de 96 sujetos, con una división de rangos militares de la siguiente manera: teniente (n= 28), capitán (n=23), mayor (n=15), teniente coronel (n=10), subteniente (n=4) y coronel (n=1). La diferencia de edad y peso entre el grupo de oficiales superiores y subalternos fue de 11,33 años (p=0,089) y 1,42 kilogramos (p=0,235), respectivamente. El valor esperado de la flexibilidad fue diferente entre grupos, siendo mayor en el grupo de oficiales subalternos (p=0,016). Conclusión: Las variables de composición corporal no presentaron diferencias estadísticamente significativas entre los grupos oficiales superiores y subalternos.

Background: Body composition in the military population is essential in the characterization of nutritional status, representing the accumulation of fat, bone, water, and total muscle in the body. Objective: Describe and analyze variables of the CP data collected from a sample of officers of the Colombian National Army. Methodology: Descriptive study among officers in order to determine body composition and bioimpedance with nutritional status as an indicator of health risks, using a height rod, a scale with a precision of 100 grams, a flexible anthropometric tape, a small diameter compass and skinfold compass. A statistically significant p value of <0.05 is considered. Results: The sample of officers collected is composed of a total of 96 subjects with a division of military ranks as follows: lieutenant (n= 28), captain (n=23), major (n=15), lieutenant colonel ( n=10), second lieutenant (n=4) and colonel (n=1). The difference in age and weight between the group of senior and junior officers was 11.33 years (p=0.089) and 1.42 kilograms (p=0.235), respectively. The expected value of flexibility is different between groups, being higher in the group of junior officers (p=0.016). Conclusion: The body composition variables did not present statistically significant differences between the superior and subordinate official groups.

La salud pública matancera durante el período de ocupación militar norteamericana 1899-1902

Introducción: el 1 de enero de 1899 inició la ocupación militar de Cuba por Estados Unidos, cuyo objetivo fundamental fue sentar las bases de la futura República neocolonial. Objetivo: describir el comportamiento de la salud pública matancera durante el período de ocupación militar norteamericana 1899-1902. Materiales y métodos: se utilizó el método histórico descriptivo para estudiar el comportamiento de la salud pública matancera en el período de ocupación militar, y se realizó la revisión bibliográfica y documental. Resultados: no obstante los logros sociales -en especial en el ámbito de la salud pública-, las medidas y posiciones antinacionales que adoptó el gobierno interventor encontraron el rechazo de las clases y sectores interesados en lograr la absoluta soberanía de Cuba. Conclusiones: los matanceros realizaron notables esfuerzos para enfrentar la difícil situación sanitaria a través de la apertura de hospitales e instituciones, que brindaban servicios, sobre todo, a los sectores pobres de la población, y de la campaña de higienización para evitar la propagación de enfermedades y epidemias.

Introduction: the period of U.S. military occupation in Cuba officially began on January 1, 1899. Its main objective was to lay the foundation of the future neocolonial republic. Objective: to describe the behavior of Matanzas public health during the period of the US military occupation 1899-1902. Materials and methods: the historical descriptive method was used to study the behavior of Matanzas public health in the period of military occupation, and a bibliographic and documental review was conducted. Results: despite the social achievements- especially in the field of public health-, antinational measures and positions adopted by the intervening government found the rejection of the classes and sectors interested in achieving the absolute sovereignty of Cuba. Conclusions: the people of Matanzas made notable efforts to face the difficult sanitary situation opening hospitals and institutions which provided services, above all, to the poor sectors of the population, and to carry out a sanitation campaign to prevent the spread of diseases and epidemics.

Factores asociados al miedo por la información recibida durante la pandemia en policías y militares peruanos

Introducción: Para policías y militares, el acceso a información idónea y veraz siempre ha sido importante; durante la pandemia la necesidad fue aún mayor debido a las labores que les fueron asignadas, como parte de la primera línea frente a la pandemia por la COVID-19. Objetivo: Determinar los factores asociados al miedo por la información recibida durante la pandemia en policías y militares peruanos. Métodos: Estudio transversal con técnicas analíticas, se encuestó a 1 017 policías y militares peruanos durante la pandemia, para ello se usó un test validado para medir la percepción de miedo o preocupación que transmitían los medios de comunicación, se informaron las frecuencias y resultados analíticos. Resultados: Los encuestados percibieron mucho miedo a las redes sociales (22 % muy de acuerdo y 36 % de acuerdo) y la televisión (20 % muy de acuerdo y 32 % de acuerdo). En el modelo multivariado, los militares percibían menos miedo en comparación de los policías (RPa: 0,65; IC95 %: 0,49-0,88; valor p= 0,004), además, internet fue el medio que generó una mayor frecuencia de percepción de miedo entre los encuestados (RPa: 1,65; IC95 %: 1,04-2,61; valor p= 0,032), ajustado por 3 variables. Conclusión: La televisión y las redes sociales son los principales medios que generaron miedo entre los policías y militares; además, el estar asustado estuvo más asociado a informarse por internet.

Introduction: For police and military, access to suitable and truthful information has always been important, during the pandemic the need was even greater due to the tasks assigned to them as part of the front line against the COVID-19 pandemic. Objective: To determine the factors associated with fear of pandemic information received by Peruvian police and military personnel. Methods: Cross-sectional study with analytical procedures, 1 017 Peruvian police and military were surveyed, through surveys conducted during the pandemic, a validated test was used to measure the perception of fear or concern transmitted by the media, the frequencies and analytical results were reported. Results: The respondents perceived a lot of fear of social networks (22% strongly agree and 36% agree) and television (20% strongly agree and 32% agree). In the multivariate model, the military perceived less fear compared to the police (aPR: 0.65; CI95%: 0.49-0.88; value p= 0.004), in addition, the Internet was the medium that generated a greater frequency of perception of fear among the respondents (aPR: 1.65; CI95%: 1.04-2.61; value p= 0.032), adjusted for 3 variables. Conclusion: Television and social networks are the main media that generate fear among police and military; in addition, being scared was more associated with being informed through the Internet.

Research progress in characteristics and field surgical treatment of craniocerebral war injury in foreign armies / 中华创伤杂志

Craniocerebral war injury, mainly caused by weaponry equipment and wartime conditions during warfare, are characterized by high difficulty in treatment and evacuation as well as high mortality rate. The field surgical treatment of craniocerebral war injury is not only related to injury characteristics, but also to factors such as war scale, combat style, combat area and weapon power. In recent years, there have been few comprehensive reports on the characteristics and field surgical treatment of craniocerebral war injury in China. Therefore, the authors reviewed the research progress in the characteristics and field surgical treatment of craniocerebral war injuries in foreign armies since 2001, with the aim to provide a reference for relevant basic researches and war injury treatment in China.

Practice and exploration of online teaching in clinical medicine education in military teaching hospitals / 中华医学教育探索杂志

With the rapid development of information technology and the change in military education policy in the new era, online teaching has gradually become one of the main approaches to implement the clinical medical education in military teaching hospitals. In this study, the online teaching was performed mainly by pre-recorded teaching, supplemented by online live teaching. Massive open online courses (MOOCs) and the seminar-style teaching were advocated to be used in advanced disciplines. The quality of online teaching was guaranteed through infrastructure provision, teacher arrangement, teaching preparation, teaching interactivity, after-class test, teaching evaluation, supervision, and summary of teaching, which ultimately achieved a good effect. The results of the two-way questionnaires of 26 teachers and 129 students showed that 23.26% (30/129) of students and 65.38% (17/26) of teachers believed that students' learning ability was insufficient. 34.88% (45/129) of students and 23.08% (6/26) of teachers thought that the existing technology could not meet the requirements of online teaching. 55.04% (71/129) of students and 69.23% (18/26) of teachers held the view that the effect of online teaching was inferior to face-to-face teaching. 28.68% (37/129) of students and 57.69% (15/26) of faculty asked for the return of face-to-face education. Therefore, it is necessary to strengthen the construction of smart classroom platforms, establish a well-developed online teaching quality evaluation system, and integrate various innovative teaching modes with the online teaching. In these ways, it is expected to optimize the online teaching of clinical medicine and achieve the goal of online teaching.

Effect of social support on psychological adaptation in military freshmen: The mediating effect of resilience / 中华医学教育探索杂志

Objective:To investigate the relationship between resilience, perceived social support, and adaptability in military freshmen.Methods:A total of 195 freshmen were randomly selected from a military medical university. The Chinese version of Connor-Davidson Resilience Scale (CD-RISC), the Perceived Social Support Scale (PSSS), and a self-test questionnaire of college students' psychological adaptability were used to investigate their resilience, perceived social support, and adaptability. SPSS 26.0 was used to perform an independent samples t-test and a Pearson correlation analysis to analyze the differences in these scores between freshmen with different demographic characteristics and the correlation between these scores. By using the PROCESS plug-in, a structural equation model was used to analyze the mediating effect of resilience on the relationship between social support and psychological adaptation, which was further tested using the Bootstrap method. Results:The independent samples t-test showed that females had a significantly higher score of other support than males ( t = -2.05, P = 0.041), and student leaders had significantly higher scores of family support and other support, total score of social support, and score in psychological adaptability than other students (all P<0.05). The correlation analysis showed that there were significant positive correlations between the scores of PSSS and its each item, CD-RISC, and self-test of college students' psychological adaptability (all P<0.05). The structural equation model showed that resilience partially mediated the relationship between social support and psychological adaptation, and the Bootstrap method revealed a significant indirect effect (95%CI: 0.102-0.253). Conclusion:Resilience plays a partial mediating role between perceived social support and adaptability in military freshmen. They should be guided to correctly perceive external support and develop strong resilience.

Construction of the post competency model of clinical medicine students in military medical universities / 中华医学教育探索杂志

Objective:To establish a post competency model for clinical medical students in military medical universities to explore the qualities most needed by outstanding graduates.Methods:Through behavioral event interview (BEI) method, the complete interview data of 82 graduates (40 students in excellent group and 42 students in normal group) from a military medical university were obtained. The respondents were asked to recall the three most successful and unsuccessful cases in their past work, and fill in the checklist. The interview data were coded, marked and classified, the interview recording data were analyzed, and the comparison was made between the frequency of competency characteristics and the collection points of excellent graduates.Results:Top 9 competency features with the highest frequency and no difference between the two groups were respectively internal quality (82 students, 100%), clinical medical service capacity (52 students, 63.4%), continuous learning ability (36 students, 43.9%), teamwork ability (38 students, 46.3%), career (66 students, 80.5%), enterprise (46 students, 56.1%), sense of responsibility (42 students, 51.2%), execution (42 students, 51.2%), and coordination of team members (36 students, 44.0%). The proportions of excellent graduates to mention the ability to apply information tools ( χ2=6.80, P=0.009),; master English literature ( χ2=4.42, P=0.036), and be self-disciplined and fame and fortune-weakened ( χ2=6.90, P=0.009) were higher than those of the ordinary ones. Conclusion:This study has scientifically constructed a post competency model for clinical medicine students in military medical universities, including the benchmark competency model (9 characteristics with the highest frequency and non-differentiated between two groups) and the identification competency model (3 characteristics of excellent graduates higher than those of ordinary ones).

Oral Health in the Naval Armed Forces: A Scoping Review

@#Naval armed forces are commonly prone to stressors during military activities which are associated with their working environment. This can adversely impact the oral health of these personnel. This scoping review aimed to explore the literature concerning oral health among naval personnel. Relevant articles that reported oral health among naval armed forces published from 1990 to December 2022 were retrieved from five main databases. Of the 641 articles searched, 15 met the inclusion and exclusion criteria. Occurrences of caries, periodontal disease and barodontalgia were high among the naval armed forces, with a significant number of dental emergencies during deployment and training operations. The dental diseases and emergencies experienced by the naval personnel on duty may influence their performance during missions. Given the far-reaching effects of dental diseases among personnel in the naval armed forces, further prospective studies with standardised report investigating oral health and dental diseases are recommended. Oral health services in the naval armed forces can also be improved by increasing the dentist-to-navy personnel ratio both at the military bases and on board the vessels during missions, as well as designing preventive strategies to improve oral health among the naval personnel.
