ABSTRACT
Objective: This study investigated the impact of war exposure on post-traumatic stress symptoms (PTSS) and sleep disturbance across Ukraine. Subjective and objective indicators of war exposure were modelled as predictors of these symptoms.Methods: We created two predictors: first, we used governmental and crowd-sourced data to create an objective war exposure index for each of the 21 non-occupied regions of Ukraine, based on the number of air raid alarms, explosions, and proximity to frontline; and second, we obtained self-report cross-sectional data, using convenience sampling, from a nation-wide survey (N = 991) on subjective experience of threat triggered by the war. The survey also measured the outcome variables of PTSS and sleep disturbance. Hierarchical multilevel regressions modelled the relationship of this objective war exposure index with the two outcome variables, after accounting for demographics. A final regression step modelled subjective threat as predictor of these symptoms.Results: We observed strongly elevated levels of PTSS and sleep disturbance and strong regional differences in objective and subjective war indicators. Objective war exposure predicted PTSS but not sleep disturbance, whereas subjective threat predicted both symptom domains.Conclusion: The study demonstrates the utility of objective war exposure data for predicting the prevalence of PTSS in the different regions. The results further underscore the prominent role of subjective appraisal processes in the symptomatology of PTSS and sleep disturbance, thus informing theories on trauma-related disorders. Our results can guide the allocation of mental health services by identifying highly affected regions.
Objective data on air raid alarms and explosions have been prospectively collected in Ukraine.We related those objective data to symptom reports of 991 responders in most Ukraine regions.Objective data explained symptoms of post-traumatic stress but not sleep disturbance.

OBJECTIVES: A growing body of research shows that early-life exposure to war has adverse effects on later-life health. Research has emphasized the importance of exposure timing implicating domain-specific developmental processes and associated critical/sensitive periods. This study looks at the impacts of early childhood war exposure and the repercussions for later-life physical and functional health, with a focus on time of exposure as a source of variability. METHODS: We use residential histories from the Survey of Health Ageing, and Retirement in Europe linked to external data on the location and timing of hostilities to examine the impact of early-life exposure to World War II on later-life physical and functional health. RESULTS: Exposure to war increases the risk of objective (grip strength, chair rise, and peak expiratory flow) and self-reported (mobility limitations and activities of daily living) measures of functional health. Effects are especially pronounced for those born during the war and for those with more prolonged exposures. There is little evidence that the impact of war is mediated by war-related hardships, socioeconomic conditions, health behaviors, or adult chronic disease. DISCUSSION: Our results suggest early-life exposure to war has a lasting impact on physical functional health. Exposure appears to largely operate via direct effects, indicative of altered initial development of physical capacity in early life. Because exposure was so pervasive among some cohorts of older individuals, understanding the health of present older European populations requires wrestling with the residual consequences of wartime exposure at the start of their lives.

The study of the effects of war exposure on the psychological health of combatants has so far been constrained by possible selection biases which limits the establishment of causality, the clear identification of dynamics, and the generalizability of findings. In this study, we make use of a population-level natural experiment enabled by the strict military conscription system in Turkey which uses a draft lottery to randomly allocate conscripts to bases across the country, including those south-eastern areas experiencing a long running civil conflict. We build on this setting with a representative field survey of 5024 adult males. Our results indicate that those exposed to high intensity armed conflict environments during their service are more likely to experience depressive symptoms even long after their discharge. Further detailing conflict exposure, we find war traumas to be the primary drivers of the effects we observe.

Resumen El objetivo fue analizar las formas de afrontamiento de las violencias sexuales en mujeres víctimas sobrevivientes y su participación en los procesos de construcción de paz. Fue una investigación cualitativa a través de la Teoría Fundamentada, con el Interaccionismo Simbólico para originar la teoría, desde los significados que surgen en la interacción entre las personas y su entorno. Se recolectó la información con entrevistas a profundidad. La teoría construida resalta la experiencia de las violencias sexuales, la cual simboliza desazón, exilio, destrucción de sus metas y proyectos, la dificultad para perdonar por la magnitud del daño e incumplimiento de las leyes. Aunado a esto, las condiciones del territorio y su historia influyeron en los significados que las personas participantes asignaron a su experiencia inolvidable por las huellas del dolor; una de las formas de afrontamiento fue poder alzar su voz como un instrumento fundamental para el tránsito de víctimas a la legitimidad como constructoras de paces. Se concluye que, en la unión y en la mutualidad, encontraron la manera de legitimar sus voces y hacerlas oír por sus comunidades. El significado de la paz en las mujeres está representado en el estar en armonía, disfrutar de su cotidianidad, sentirse libres, sentirse importantes y únicas cuando hablan de la historia de dolor.
Abstract The objective was to analyze the ways of coping with sexual violence in surviving female victims and their participation in peacebuilding processes. It was a qualitative investigation through Grounded Theory, with Symbolic Interactionism to originate the theory, from the meanings that arise in the interaction between people and their environment. Information was collected through in-Depth interviews. The constructed theory highlights the experience of sexual violence, which symbolizes embodies the despair, exile, destruction of their goals and projects, the difficulty to forgive for the magnitude of the damage, and non compliance with the laws. In addition to this, the conditions of the territory and its history influenced the meanings that they assigned to their experience, duly unforgettable due to the traces of pain. One of the ways of coping was to be able to raise their voice as a fundamental instrument, for the transit of victims to legitimacy, as peace builders. We conclude that, in union and mutuality, they found the way to legitimize their voices and make them heard by their communities. The meaning of peace in women is represented by being in harmony, enjoying their daily lives, feeling free, feeling important and unique when they talk about their history of pain.

Increasing research shows pubertal development accelerates following threats while it decelerates following deprivation. Yet, these environmental stressors are unlikely to occur in isolation. We investigated how war exposure and energetic stress impact pubertal development using data from the longitudinal Biological Pathways of Risk and Resilience in Syrian Refugee Children study. Our sample included 1,600 male and female Syrian refugee children and their caregivers who lived in temporary settlements in Lebanon. We hypothesized that (a) energetic stress suppresses pubertal development; (b) war exposure accelerates pubertal timing in boys and increases risk of menarche in girls, but only when energetic stress is low; and (c) when energetic stress is elevated, effects of war exposure on pubertal development will be attenuated. Among boys, we did not find support for Hypothesis 1, but Hypotheses 2 and 3 were supported. Exposure to morbidity/mortality threats accelerated pubertal timing; this effect was attenuated under conditions of elevated energetic stress. Among girls, we found support for Hypothesis 1, but not for Hypotheses 2 and 3. Elevated energetic stress decreased the risk of menarche in girls. Neither war exposure, nor any interactions with energetic stress, predicted risk of menarche. Sensitivity analyses revealed a significant interaction between bombing exposure and the amount of time since leaving Syria. Bombing decreased the risk of menarche, but only for girls who had left Syria four or more years prior to data collection. We discuss implications for translational efforts advocating for puberty screening in medical and mental health settings to identify trauma-exposed youth.

BACKGROUND: War and natural disasters lead to forced migration - and increased risk of adverse psychological outcomes - in approximately 1% of the global population. Though recent years have brought a greater understanding of the consequences of war exposure on mental health outcomes for refugee children, little is known about the longitudinal and developmental impact of these experiences on youth. AIMS: The aim of this study was to assess the effect of direct exposure to war and/or combat on trajectories of symptoms related to anxiety and post-traumatic stress disorder (PTSD) in Syrian and Iraqi refugee youth following resettlement. Prevalence of possible anxiety disorders and PTSD was also assessed. METHOD: Participants included accompanied refugee youth resettled in the state of Michigan in the U.S. (n = 74). Youth filled out self-report measures of trauma exposure, anxiety symptoms, and PTSD symptoms upon arrival and 2 years later. Linear mixed-effects modeling was used to assess the effect of war exposure over time. RESULTS: Upon arrival, 38% screened positive for an anxiety disorder and 4.1% met diagnostic thresholds for PTSD. While war exposure did not predict changes to PTSD symptom trajectories (p = .481), anxiety symptoms increased over time among children reporting war exposure (B = 10.13, SE = 4.22, t = 2.40, p = .019). CONCLUSIONS: Our findings suggest that without appropriate interventions, anxiety- and trauma-related symptoms often do not decrease. Further, exposure to war trauma may lead to progressive worsening of symptoms. These findings suggest that assessing for type of trauma exposure, rather than focusing solely on migration status, may inform focused attention and interventions among trauma-exposed children resettling as refugees.

BACKGROUND: High rates of posttraumatic stress disorder (PTSD) have been documented in war-affected populations. The prevalence of Complex PTSD (CPTSD) has never been assessed in an active war zone. Here, we provide initial data on war-related experiences, and prevalence rates of ICD-11 PTSD and CPTSD in a large sample of adults in Ukraine during the Russian war. We also examined how war-related stressors, PTSD, and CPTSD were associated with age, sex, and living location in Ukraine. METHOD: Self-report data were gathered from a nationwide sample of 2004 adult parents of children under 18 from the general population of Ukraine approximately 6 months after Russia's invasion. RESULTS: All participants were exposed to at least one war-related stressor, and the mean number of exposures was 9.07 (range = 1-26). Additionally, 25.9% (95% CI = 23.9%, 27.8%) met diagnostic requirements for PTSD and 14.6% (95% CI = 12.9%, 16.0%) met requirements for CPTSD. There was evidence of a strong dose-response relationship between war-related stressors and meeting criteria for PTSD and CPTSD. Participants who had the highest exposure to war-related stressors were significantly more likely to meet the requirements for PTSD (OR = 4.20; 95% CI = 2.96-5.95) and CPTSD (OR = 8.12; 95% CI = 5.11-12.91) compared to the least exposed. CONCLUSIONS: Humanitarian responses to the mental health needs of the Ukrainian population will need to take account of posttraumatic stress reactions. Education in diagnosing and treating PTSD/CPTSD, especially in the situation of a significant lack of human resources and continuing displacement of the population, is necessary.

OBJECTIVES: War-exposed refugee children are at elevated risk for mental health problems, but a notable proportion appear resilient. We aimed to investigate the proportion of Syrian refugee children who can be considered resilient, and applied a novel approach to identify factors predicting individual differences in mental health outcomes following war exposure. METHODS: The sample included 1,528 war-exposed Syrian refugee children and their primary caregiver living in refugee settlements in Lebanon. Children were classed as having low symptoms (LS) if they scored below clinically validated cut-offs for post-traumatic stress disorder (PTSD), depression and externalising behaviour problems. Children scoring above any cut-off were classified as having high symptoms (HS). Each LS child was matched with one HS who reported similar war exposure, to test what differentiates children with similar exposures but different outcomes. RESULTS: 19.3% of the children met our resilience criteria and were considered LS. At the individual level, protective traits (e.g. self-esteem; OR = 1.51, 95% CI [1.25, 1.81]) predicted LS classification, while environmental sensitivity (OR = 0.69, 95% CI [0.59, 0.82]), poorer general health (OR = 0.71, 95% CI [0.58, 0.87]) and specific coping strategies (e.g. avoidance; OR = 0.90, 95% CI [0.85, 0.96]) predicted HS classification. Social/environmental predictors included perceived social support (OR = 1.23, 95% CI [1.02, 1.49]), loneliness and social isolation (OR = 0.85, 95% CI [0.80, 0.90]), child maltreatment (OR = 0.96, 95% CI [0.94, 0.97]), and caregiver mental and general health (e.g. caregiver depression; OR = 0.94, 95% CI [0.92, 0.97]). CONCLUSIONS: Future research should take multiple dimensions of functioning into account when defining risk for mental health problems and consider the identified predictors as potential targets for interventions.

ObjectiveWe explore how earlier-life military roles and war trauma associate with later-life respiratory health in Vietnam. Method: The population-based sample aged 60+ is from the 2018 Vietnam Health and Aging Study. Poisson and binary logistic regressions investigate correlates of overall lung health, measured as total number of four conditions, and individual conditions, with focus on earlier-life wartime experiences. Results: Exposure is associated with lung conditions. Overall, a one-standard deviation increase in exposure results in 0.529 more conditions (p ≤ .001). Association varies across military roles and is partially explained by PTSD and smoking. Civilians heavily exposed to war trauma exhibit worse lung health than similarly exposed formal and informal military personnel. Discussion: Earlier-life war exposure is an important predictor of late-adulthood respiratory health in lower- and middle-income countries. Evidence calls for attention to the long-term impacts of war on health among not only formal and informal military personnel but also civilians.

Altered secretion of cortisol, the primary effector of the hypothalamus-pituitary-adrenal axis, has been proposed as a means by which traumatic experiences compromise later mental health. However, despite the popularity of cortisol as a potential biomarker for stress and adversity, findings are inconsistent, and little is known about the impact of war-related trauma on stress physiology of children and adolescents. Here we aimed to evaluate the relationships between war exposure, current living conditions, hair cortisol concentrations (HCC) and post-traumatic stress disorder (PTSD) symptoms in a large cohort of Syrian refugee children and adolescents (6-18 years) and their caregiver. This longitudinal observational study assessed Syrian refugee children and adolescents in two waves, 1 year apart, within informal tented settlements in Lebanon. The relationships between war exposure, time since leaving Syria, PTSD symptoms and HCC were investigated using linear mixed-model regression utilising both waves of data collected (Y1: N = 1574, Y2: N = 923). Hair cortisol concentration was positively, but weakly associated with the number of war-related events experienced. This was limited to those who were at least 12 years old at the time of war exposure. Conversely, HCC decreased with time since leaving Syria. HCC was also associated with PTSD symptoms but not with the quality of their current living conditions. This study revealed that changes to hypothalamic-pituitary-adrenal axis activity may accompany both earlier war exposure and current PTSD symptoms in children and adolescents. Additionally, early adolescence may be a particularly sensitive time in terms of trauma-related changes to the hypothalamic-pituitary-adrenal axis.

Childhood exposure to contexts of war is a common occurrence among current and recent cohorts of children in various parts of the world. It was also common among older cohorts across Europe. Utilizing the Survey of Health, Ageing, and Retirement in Europe (SHARE) the present study links early life course residential histories with detailed information on the timing and location of hostilities during WWII to address three questions: 1) is childhood exposure to war associated with earlier onset of cardiometabolic disease (cardiovascular disease, hypertension, high cholesterol, and diabetes)? 2) did this additional risk vary depending on the timing of first exposure? 3) did this additional risk manifest via different life course pathways depending on exposure timing? Results demonstrate that exposure to war is associated with increased lifetime risk of cardiovascular disease, diabetes, high cholesterol, and hypertension and that this association is strongly concentrated among cohorts exposed in utero or during early childhood (e.g., before age 8). The results also suggest that the impact of war exposure on cardiometabolic disorders are likely to be direct, operating through latent biological processes rather than through childhood hardship, stunting of adult socioeconomic attainment, or elevated risk-taking behaviors.

OBJECTIVES: Exposure to maternal stress during the prenatal period adversely affects child outcomes. Recent investigations have shifted to an even earlier period, the preconception period, to better understand the role of this formative period in human health and disease. We investigated the links between maternal emotional distress following preconception exposure to war, and child outcomes at age 10. MATERIAL AND METHODS: Before becoming pregnant, mothers were exposed to missile bombardment on the north of Israel in the 2006 war. Mothers who conceived within 12 months after the war were recruited and compared to mothers who conceived during the same period but lived in Israel but outside missile range. During the initial assessment, mothers completed a questionnaire on emotional distress. At 10 years of age, mothers and children (N = 68) reported on child socio-emotional outcomes. RESULTS: Multiple regression analyses revealed that, in girls, higher maternal emotional distress following preconception war exposure predicted more internalizing and externalizing behavior problems, and more behavior regulation problems. In boys, maternal emotional distress was not significantly related to outcomes. CONCLUSION: Maternal emotional distress following preconception exposure to war forecasts sex-specific child behavioral problems as reported by the mother and the child. Though the results warrant cautious interpretation because of the relatively small sample size and differential attrition, our findings add to the small but growing body of research on the consequences of maternal stress exposure prior to conception for the next generation.

OBJECTIVES: This study aimed to assess the nature and degree of association between exposure to potentially traumatic wartime experiences in early life, such as living in a heavily bombed region or witnessing death firsthand, and later-life frailty. METHOD: The Vietnam Health and Aging Study included war survivors in Vietnam, 60+, who completed a survey and health exam between May and August 2018. Latent class analysis (LCA) is used to construct classes exposed to similar numbers and types of wartime experiences. Frailty is measured using a deficit accumulation approach that proxies biological aging. Fractional logit regression associates latent classes with frailty scores. Coefficients are used to calculate predicted frailty scores and expected age at which specific levels of frailty are reached across wartime exposure classes. RESULTS: LCA yields 9 unique wartime exposure classes, ranging from extreme exposure to nonexposed. Higher frailty is found among those with more heavy/severe exposures with a combination of certain types of experiences, including intense bombing, witnessing death firsthand, having experienced sleep disruptions during wartime, and having feared for one's life during war. The difference in frailty-associated aging between the most and least affected individuals is more than 18 years. DISCUSSION: War trauma hastens aging and warrants greater attention toward long-term implications of war on health among vast postconflict populations across the globe.

Abstract: Sulfur mustard is one of the chemical warfare agent. It rapidly reacts with the cutaneous tissues and other tissues, leading to various devastating long-term effects on human health. Mustard-exposed veterans suffer from its chronic skin problems, including itching, burning sensation, and eczema. We aimed to evaluate the protective effects of Myrtus communis L. (myrtle) on chronic skin lesions and quality of life of sulfur mustard-exposed veterans. In this randomized, double-blind clinical trial, 60 sulfur mustard-exposed patients were evaluated. Thirty patients received myrtle essence 5% cream (case group) and 30 patients received Eucerin cream (placebo group) twice in a day for one month. Then, We assessed the chronic skin problems and itching-related parameters (such as the itching time, severity, distribution, frequency, and calculated itching score), duration of sleep, number of waking up at night, and quality of life in the both groups. Our analysis of data revealed that application of myrtle cream effectively decreased skin problems including; itching and burning sensation. Additionally, myrtle markedly decreased skin lesion symptoms such as excoriation in the case group as compared with before treatment. Noticeably, myrtle cream significantly improved quality of life of the patients in the case group. The present study provides more in-depth information regarding the protective role of myrtle on the sulfur mustard-induces skin complication. Also, myrtle effectively improved quality of life of the sulfur mustard-exposed veterans.

While peritraumatic negative emotions have been associated with subsequent posttraumatic stress and depression, the predictive role of real-time emotional reactions to specific stressors during prolonged stress exposure is still unclear, particularly that of positive emotions. The current study uses experience sampling methodology to examine individual general levels of negative and positive emotions, and emotional reactivity to specific stressors during war, as prospective predictors of posttraumatic stress and depression. Ninety-six civilians exposed to rocket fire during the 2014 Israel-Gaza war reported exposure to rocket warning sirens and levels of ten negative and six positive emotions twice a day for 30 days. Symptoms of posttraumatic stress and depression were then assessed two months post-war. Participants reported higher negative emotions and lower positive emotions during assessment windows with sirens. Over time, negative emotions decreased and positive emotions increased. Higher levels of overall negative emotions predicted posttraumatic stress symptoms and depression symptoms two months later. Levels of positive emotions, and negative and positive emotional reactivity to sirens, were not associated with subsequent symptomatology. Our results indicate the stronger role of overall negative emotions as predictors of symptomatology compared with momentary emotional reactivity, and the stronger predictive role of negative compared with positive emotions.

Most Vietnamese young adults who experienced the American War were exposed to war-related violence, which can exert a lifelong impact. We analyze survey data collected among northern and central Vietnamese older adults in the 2018 Vietnam Health and Aging Study (N = 2,447) to examine the association between various war traumas, psychological distress, and suicidal ideation. Informed by life course and stress process perspectives, we use structural equation models with multiple mediators to analyze the relationship between mental health outcomes and five types of wartime stress exposure: loss of family and friends, witnessing death, malevolent living conditions, life threat, and moral injury. Our findings reveal enduring mental health impacts of war among survivors. Wartime stress exposure's influence on mental health is mediated by recent comorbidities and stressful life events. Loss of family members, witnessing death, and malevolent living conditions during war are particularly salient risks for psychological distress.

Objective: The aim of this study was to estimate the association between self-reported perceived danger during deployment, measured as combat exposure or witnessing the consequences of war, and post-deployment suicide attempts among military personnel. Furthermore, the effect of post-deployment symptoms of posttraumatic stress disorder (PTSD) and/or depression on the risk of suicide attempts was also evaluated.Methods: This observational cohort study included Danish Army military personnel who returned from deployment in international missions from 1998 to 2016 and had completed a post-deployment questionnaire. Perceived exposure to danger was ascertained by self-report. Data on suicide attempt were retrieved from national registers. Adjusted Cox regression analyses were used to evaluate if military personnel indicating high level of combat exposure were more likely to have attempted suicides post-deployment than military personnel with lower levels of combat exposure.Results: Eighty-three suicide attempts were registered after homecoming among 12,218 military personnel. Perceived higher exposure to combat was associated with the risk of suicide attempt (hazard ratio = 1.08; 95% CI, 1.01-1.16). Furthermore, the association between combat exposure and suicide attempt was fully mediated by post-deployment symptoms of PTSD and/or depression. No association was found between witnessing consequences of war and the risk of post-deployment suicide attempt.Conclusions: This nationwide study found that combat exposure was associated with an increased risk of suicide attempt among military personnel. This association was, however, fully mediated by mental disorders (PTSD and/or depression). These findings suggest that better psychological follow-up of military personnel identified as having PTSD and/or depression may be warranted.

BACKGROUND: Armed conflicts have major indirect health impacts in addition to the direct harms from violence. They create enduring political instability, destabilise health systems, and foster negative socioeconomic and environmental conditions-all of which constrain efforts to reduce maternal and child mortality. The detrimental impacts of conflict on global maternal and child health are not robustly quantified. This study assesses the association between conflict and maternal and child health globally. METHODS AND FINDINGS: Data for 181 countries (2000-2019) from the Uppsala Conflict Data Program and World Bank were analysed using panel regression models. Primary outcomes were maternal, under-5, infant, and neonatal mortality rates. Secondary outcomes were delivery by a skilled birth attendant and diphtheria, pertussis, and tetanus (DPT) and measles vaccination coverage. Models were adjusted for 10 confounders, country and year fixed effects, and conflict lagged by 1 year. Further lagged associations up to 10 years post-conflict were tested. The number of excess deaths due to conflict was estimated. Out of 3,718 country-year observations, 522 (14.0%) had minor conflicts and 148 (4.0%) had wars. In adjusted models, conflicts classified as wars were associated with an increase in maternal mortality of 36.9 maternal deaths per 100,000 live births (95% CI 1.9-72.0; 0.3 million excess deaths [95% CI 0.2 million-0.4 million] over the study period), an increase in infant mortality of 2.8 per 1,000 live births (95% CI 0.1-5.5; 2.0 million excess deaths [95% CI 1.6 million-2.5 million]), a decrease in DPT vaccination coverage of 4.9% (95% CI 1.5%-8.3%), and a decrease in measles vaccination coverage of 7.3% (95% CI 2.7%-11.8%). The long-term impacts of war were demonstrated by associated increases in maternal mortality observed for up to 7 years, in under-5 mortality for 3-5 years, in infant mortality for up to 8 years, in DPT vaccination coverage for up to 3 years, and in measles vaccination coverage for up to 2 years. No evidence of association between armed conflict and neonatal mortality or delivery by a skilled birth attendant was found. Study limitations include the ecological study design, which may mask sub-national variation in conflict intensity, and the quality of the underlying data. CONCLUSIONS: Our analysis indicates that armed conflict is associated with substantial and persistent excess maternal and child deaths globally, and with reductions in key measures that indicate reduced availability of organised healthcare. These findings highlight the importance of protecting women and children from the indirect harms of conflict, including those relating to health system deterioration and worsening socioeconomic conditions.

Gulf War Illness (GWI) is defined by the Centers for Disease Control and Prevention (CDC) as a multi-symptom illness having at least one symptom from two of three factors, which include: fatigue, mood-cognition problems, and musculoskeletal disorders. The cluster of long-term symptoms is unique to military personnel from coalition countries including United States, Australia, and the United Kingdom that served in Operation Desert Storm from 1990 to 1991. Reporting of these symptoms is much lower among soldiers deployed in other parts of the world like Bosnia during the same time period. The exact cause of GWI is unknown, but combined exposure to N,N-diethyl-m-toluamide (DEET), organophosphates like chlorpyrifos (CPF), and pyridostigmine bromide (PB), has been hypothesized as a potential mechanism. Mitochondrial dysfunction is known to occur in most neurodegenerative diseases that share symptoms with GWI and has therefore been implicated in GWI. Although exposure to these and other toxicants continues to be investigated as potential causes of GWI, their combined impact on mitochondrial physiology remains unknown. In this study, the effects of combined GWI toxicant exposure on mitochondrial function were determined in a commonly used and readily available immortalized cell line (N2a), whose higher rate of oxygen consumption resembles that of highly metabolic neurons in vivo. We report that combined exposure containing pesticide CPF 71 µM, insect repellants DEET 78 µM, and antitoxins PB 19 µM, causes profound mitochondrial dysfunction after a 4-h incubation resulting in decreased mitochondrial respiratory states in the absence of proapoptotic signaling, proton leak, or significant increase in reactive oxygen species production.
