Role of vaccinations as risk factors for ill health in veterans of the Gulf war: cross sectional study

ObjectivesTo explore the relation between ill health after the Gulf war and vaccines received before or during the conflict. To test the hypothesis that such ill health is limited to military personnel who received multiple vaccines during deployment and that pesticide use modifies any effect.DesignCross sectional study of Gulf war veterans followed for six to eight years after deployment.Setting UK armed forces.ParticipantsMilitary personnel who served in the Gulf and who still had their vaccine records.Results The response rate for the original survey was 70.4% (n=3284). Of these, 28% (923) had vaccine records. Receipt of multiple vaccines before deployment was associated with only one of the six health outcomes (post-traumatic stress reaction). By contrast five of the six outcomes (all but post-traumatic stress reaction) were associated with multiple vaccines received during deployment. The strongest association was for the multisymptom illness (odds ratio 5.0; 95% confidence interval 2.5 to 9.8).ConclusionAmong veterans of the Gulf war there is a specific relation between multiple vaccinations given during deployment and later ill health. Multiple vaccinations in themselves do not seem to be harmful but combined with the “stress” of deployment they may be associated with adverse health outcomes. These results imply that every effort should be made to maintain routine vaccines during peacetime.     

Mental Health Status of Sri Lanka Navy Personnel Three Years after End of Combat Operations: A Follow Up Study

The main aim of this study was to assess the mental health status of the Navy Special Forces and regular forces three and a half years after the end of combat operations in mid 2009, and compare it with the findings in 2009. This cross sectional study was carried out in the Sri Lanka Navy (SLN), three and a half years after the end of combat operations. Representative samples of SLN Special Forces and regular forces deployed in combat areas were selected using simple random sampling. Only personnel who had served continuously in combat areas during the one year period prior to the end of combat operations were included in the study. The sample consisted of 220 Special Forces and 275 regular forces personnel. Compared to regular forces a significantly higher number of Special Forces personnel had experienced potentially traumatic events. Compared to the period immediately after end of combat operations, in the Special Forces, prevalence of psychological distress and fatigue showed a marginal increase while hazardous drinking and multiple physical symptoms showed a marginal decrease. In the regular forces, the prevalence of psychological distress, fatigue and multiple somatic symptoms declined and prevalence of hazardous drinking increased from 16.5% to 25.7%. During the same period prevalence of smoking doubled in both Special Forces and regular forces. Prevalence of PTSD reduced from 1.9% in Special Forces to 0.9% and in the regular forces from 2.07% to 1.1%. Three and a half years after the end of combat operations mental health problems have declined among SLN regular forces while there was no significant change among Special Forces. Hazardous drinking among regular forces and smoking among both Special Forces and regular forces have increased.     

New onset and persistent symptoms of post-traumatic stress disorder self reported after deployment and combat exposures: prospective population based US military cohort study

Objective To describe new onset and persistence of self reported post-traumatic stress disorder symptoms in a large population based military cohort, many of whom were deployed in support of the wars in Iraq and Afghanistan.Design Prospective cohort analysis.Setting and participants Survey enrolment data from the millennium cohort (July 2001 to June 2003) obtained before the wars in Iraq and Afghanistan. Follow-up (June 2004 to February 2006) data on health outcomes collected from 50 184 participants.Main outcome measures Self reported post-traumatic stress disorder as measured by the posttraumatic stress disorder checklist—civilian version using Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria.Results More than 40% of the cohort were deployed between 2001 and 2006; between baseline and follow-up, 24% deployed for the first time in support of the wars in Iraq and Afghanistan. New incidence rates of 10-13 cases of post-traumatic stress disorder per 1000 person years occurred in the millennium cohort. New onset self reported post-traumatic stress disorder symptoms or diagnosis were identified in 7.6-8.7% of deployers who reported combat exposures, 1.4-2.1% of deployers who did not report combat exposures, and 2.3-3.0% of non-deployers. Among those with self reported symptoms of post-traumatic stress disorder at baseline, deployment did not affect persistence of symptoms.Conclusions After adjustment for baseline characteristics, these prospective data indicate a threefold increase in new onset self reported post-traumatic stress disorder symptoms or diagnosis among deployed military personnel who reported combat exposures. The findings define the importance of post-traumatic stress disorder in this population and emphasise that specific combat exposures, rather than deployment itself, significantly affect the onset of symptoms of post-traumatic stress disorder after deployment.     

Historical approaches to post-combat disorders

Almost every major war in the last century involving western nations has seen combatants diagnosed with a form of post-combat disorder. Some took a psychological form (exhaustion, combat fatigue, combat stress reaction and post-traumatic stress disorder), while others were characterized by medically unexplained symptoms (soldier's heart, effort syndrome, shell shock, non-ulcer dyspepsia, effects of Agent Orange and Gulf War Syndrome). Although many of these disorders have common symptoms, the explanations attached to them showed considerable diversity often reflected in the labels themselves. These causal hypotheses ranged from the effects of climate, compressive forces released by shell explosions, side effects of vaccinations, changes in diet, toxic effects of organophosphates, oil-well fires or depleted-uranium munitions. Military history suggests that these disorders, which coexisted in the civilian population, reflected popular health fears and emerged in the gaps left by the advance of medical science. While the current Iraq conflict has yet to produce a syndrome typified by medically unexplained symptoms, it is unlikely that we have seen the last of post-combat disorders as past experience suggests that they have the capacity to catch both military planners and doctors by surprise.     

Two faces of death: fatalities from disease and combat in America's principal wars, 1775 to present

Throughout America's first 145 years of war, far more of the country's military personnel perished from infectious diseases than from enemy action. This enduring feature of war was finally reversed in World War II, chiefly as a result of major medical advances in prevention (vaccines) and treatment (antibiotics). Safeguarding the health of a command is indispensable for the success of any campaign. Wars are lost by disease, which causes an enormous drain on the military's resources and affects both strategy and tactics. Disease and combat mortality data from America's principal wars (1775-present) fall into two clearly defined time periods: the Disease Era (1775-1918), during which infectious diseases were the major killer of America's armed forces, and the Trauma Era (1941-present), in which combat-related fatalities predominated. The trend established in World War II continues to the present day. Although there are currently more than 3,400 U.S. military fatalities in Iraq, the disease-death toll is so low that it is exceeded by the number of suicides.     

Family perceptions of post-deployment healthcare needs of Iraq/Afghanistan military personnel

Nearly 40 000 service members returning from Iraq and Afghanistan have suffered traumatic injuries, with over 300 000 at risk for post-traumatic stress disorder (PTSD) or other psychiatric problems. These veterans face numerous post-deployment health concerns, sharing substantial burdens with their families. Although many rely upon community-based health care, little is known about how these individuals present at family medicine clinics for perceived medical and psychological issues. We surveyed 347 patients during visits at six clinics, and respondents reported whether they,a family member or a close acquaintance had been deployed since 2001. Patients identified traumatic military experiences, plus any attributable health or social problems. The mean patient age was 47.5 years, with 71% women and 55% Hispanic individuals. Nearly one-quarter reported family members serving overseas while 52% knew someone deployed. Significant events included nearby explosion (21%) or combat injury (9%), along with a variety of other incidents. Among the half of individuals perceiving significant health or social ramifications, the most prevalent consequences were PTSD, depression and alcohol abuse. Divorce or marital problems were noted by13%, while many reported employment, legal or other difficulties. This study offers insights into post-deployment needs of military personnel and subsequent problems reported by family members. A high prevalence of traumatic combat events translated into serious health needs, plus social disruptions for veterans and their loved ones. As the long-term problems disclosed by returning service personnel continue to ripple across community clinics and other health systems, effective treatment planning mandates coordinated attention from multiple providers and service organisations.     

Detention of British citizens as hostages in the Gulf--health,psychological, and family consequences.

OBJECTIVE--To describe the physical, psychological, and family consequences of the detention of British subjects as hostages in Kuwait or Iraq, or both, after the invasion of Kuwait on 2 August 1990 and to investigate the relation between types of trauma experienced and these reactions. DESIGN--Postal questionnaire. SUBJECTS--381 respondents. RESULTS--Many health, social, and psychological sequelae were identified. Problems with present finance, accommodation, and work are important causes of distress. Many hostages coped well and gained self esteem. CONCLUSIONS--A minority of respondents require further support and treatment. Expatriates in risk areas should retain assets in their home country.     

Neglect of medical evidence of torture in Guantánamo Bay: a case series

Background

In the wake of the September 11, 2001 attacks on the US, the government authorized the use of “enhanced interrogation” techniques that were previously recognized as torture. While the complicity of US health professionals in the design and implementation of US torture practices has been documented, little is known about the role of health providers, assigned to the US Department of Defense (DoD) at the US Naval Station Guantánamo Bay, Cuba (GTMO), who should have been in a position to observe and document physical and psychological evidence of torture and ill treatment.

Methods and Findings

We reviewed GTMO medical records and relevant case files (client affidavits, attorney–client notes and summaries, and legal affidavits of medical experts) of nine individuals for evidence of torture and ill treatment and documentation by medical personnel. In each of the nine cases, GTMO detainees alleged abusive interrogation methods that are consistent with torture as defined by the UN Convention Against Torture as well as the more restrictive US definition of torture that was operational at the time. The medical affidavits in each of the nine cases indicate that the specific allegations of torture and ill treatment are highly consistent with physical and psychological evidence documented in the medical records and evaluations by non-governmental medical experts. However, the medical personnel who treated the detainees at GTMO failed to inquire and/or document causes of the physical injuries and psychological symptoms they observed. Psychological symptoms were commonly attributed to “personality disorders” and “routine stressors of confinement.” Temporary psychotic symptoms and hallucinations did not prompt consideration of abusive treatment. Psychological assessments conducted by non-governmental medical experts revealed diagnostic criteria for current major depression and/or PTSD in all nine cases.

Conclusion

The findings in these nine cases from GTMO indicate that medical doctors and mental health personnel assigned to the DoD neglected and/or concealed medical evidence of intentional harm. Please see later in the article for the Editors'' Summary     

The Chronic Fatigue Twin Registry: method of construction, composition, and zygosity assignment.

Chronic fatigue syndrome (CFS) and the symptom of chronic fatigue are conditions of unknown etiology. The Centers for Disease Control and Prevention (CDC) define CFS as an illness characterized by > or = 6 months of disabling fatigue associated with muscle pain, pharyngitis, and alterations in mood, sleep and neurocognition. We constructed a registry of twins with chronic fatigue to facilitate research on the impact of illness, the associated medical and psychosocial factors, and the heterogeneous proposed mechanisms for these conditions. We have recruited 204 twin pairs in which one or both members reported persistent fatigue through patient support group newsletters (60%), clinicians/researchers familiar with CFS (12%), notices placed on electronic bulletin boards for CFS (11%), twin organizations and researchers (6%), relatives and friends (3%) and other sources (8%). Complete data are available for 177 pairs (87%). Twins completed an extensive questionnaire booklet that included measures of physical and mental health, functional status, and psychosocial factors; a structured psychiatric interview was also conducted by telephone. Twins were classified using three increasingly more stringent diagnostic criteria for chronic fatigue: 1) > or = 6 months of fatigue (115 discordant and 61 concordant pairs); 2) chronic fatigue with additional symptoms and application of the medial exclusions of the CDC CFS case definition as obtained by self-report (92 discordant and 41 concordant pairs) and; 3) chronic fatigue with additional symptoms unexplained by self-reported medical conditions and psychiatric diagnoses as determined by the structured interview (69 discordant pairs and 25 concordant pairs). Despite the limitations of a volunteer registry, the Chronic Fatigue Twin Registry promises to be an important resource for research on CFS and chronic fatigue.     

Medical Evidence of Human Rights Violations against Non-Arabic-Speaking Civilians in Darfur: A Cross-Sectional Study

Background

Ongoing conflict in the Darfur region of Sudan has resulted in a severe humanitarian crisis. We sought to characterize the nature and geographic scope of allegations of human rights violations perpetrated against civilians in Darfur and to evaluate their consistency with medical examinations documented in patients'' medical records.

Methods and Findings

This was a retrospective review and analysis of medical records from all 325 patients seen for treatment from September 28, 2004, through December 31, 2006, at the Nyala-based Amel Centre for Treatment and Rehabilitation of Victims of Torture, the only dedicated local provider of free clinical and legal services to civilian victims of torture and other human rights violations in Darfur during this time period. Among 325 medical records identified and examined, 292 (89.8%) patients from 12 different non-Arabic-speaking tribes disclosed in the medical notes that they had been attacked by Government of Sudan (GoS) and/or Janjaweed forces. Attacks were reported in 23 different rural council areas throughout Darfur. Nearly all attacks (321 [98.8%]) were described as having occurred in the absence of active armed conflict between Janjaweed/GoS forces and rebel groups. The most common alleged abuses were beatings (161 [49.5%]), gunshot wounds (140 [43.1%]), destruction or theft of property (121 [37.2%]), involuntary detainment (97 [29.9%]), and being bound (64 [19.7%]). Approximately one-half (36 [49.3%]) of all women disclosed that they had been sexually assaulted, and one-half of sexual assaults were described as having occurred in close proximity to a camp for internally displaced persons. Among the 198 (60.9%) medical records that contained sufficient detail to enable the forensic medical reviewers to render an informed judgment, the signs and symptoms in all of the medical records were assessed to be consistent with, highly consistent with, or virtually diagnostic of the alleged abuses.

Conclusions

Allegations of widespread and sustained torture and other human rights violations by GoS and/or Janjaweed forces against non-Arabic-speaking civilians were corroborated by medical forensic review of medical records of patients seen at a local non-governmental provider of free clinical and legal services in Darfur. Limitations of this study were that patients seen in this clinic may not have been a representative sample of persons alleging abuse by Janjaweed/GoS forces, and that most delayed presenting for care. The quality of documentation was similar to that available in other conflict/post-conflict, resource-limited settings. Please see later in the article for the Editors'' Summary     

Consecuencias de los conflictos armados en la salud mental de niños y adolescentes: revisión de revisiones de la literatura

Introduction:

Armed conflicts affect the mental health of children and adolescents. Their outcomes in these populations have been documented identifying vulnerability and significant biopsychosocial damage as the most common factors.

Objective:

To identify and synthesize the mental health consequences of armed conflicts in children and adolescents.

Materials and methods:

We carried out a comprehensive and systematic search of reviews published until July 2019 in the MEDLINE (Ovid), EMBASE, Cochrane Central Register of Controlled Trials, and LILACS databases, as well as in additional sources. The information was retrieved and analyzed narratively by describing the characteristics and objectives of the studies and the mental health consequences of armed conflicts in three periods of time: pre-armed conflict, during the armed conflict, and post-conflict.

Results.

Out of 587 potentially relevant studies, we finally selected 72. In the pre-armed conflict period, we described in detail the psychological experiences and the anticipatory somatic symptoms. During the conflict, we identified regressive, behavioral, and cognitive symptoms such as enuresis, fear, sadness, aggression, hyperactivity, and inattention, among others. Direct mental health consequences such as adjustment disorders, depression, anxiety, and post-traumatic stress were also identified. Finally, in the post-conflict period, we referred to the transmission of mental health consequences and resilience processes. On the other hand, we reviewed in depth the potential consequences of armed conflicts on biopsychosocial development, morality, identity, culture, education, and society.

Conclusion.

The development of mental health consequences due to the exposure to armed conflicts in these populations is a complex process that depends on the stage of the exposure, the length of the conflict, and contextual factors.     

Managing future Gulf War Syndromes: international lessons and new models of care

After the 1991 Gulf War, veterans of the conflict from the United States, United Kingdom, Canada, Australia and other nations described chronic idiopathic symptoms that became popularly known as 'Gulf War Syndrome'. Nearly 15 years later, some 250 million dollars in United States medical research has failed to confirm a novel war-related syndrome and controversy over the existence and causes of idiopathic physical symptoms has persisted. Wartime exposures implicated as possible causes of subsequent symptoms include oil well fire smoke, infectious diseases, vaccines, chemical and biological warfare agents, depleted uranium munitions and post-traumatic stress disorder. Recent historical analyses have identified controversial idiopathic symptom syndromes associated with nearly every modern war, suggesting that war typically sets into motion interrelated physical, emotional and fiscal consequences for veterans and for society. We anticipate future controversial war syndromes and maintain that a population-based approach to care can mitigate their impact. This paper delineates essential features of the model, describes its public health and scientific underpinnings and details how several countries are trying to implement it. With troops returning from combat in Afghanistan, Iraq and elsewhere, the model is already getting put to the test.     

Do recent leopard Panthera pardus records from northern Iraq and south-eastern Turkey reveal an unknown population nucleus in the region?

The status of leopard in Iraq and south-eastern Turkey has been unclear for decades. Because of recent and on-going armed conflicts in important parts of the potential leopard distribution range, no studies were done that could have proved the presence of the species. We report here 10 confirmed and 2 unconfirmed leopard records between 2001 and 2014 from northern Iraq and south-eastern Turkey. All records for which the gender of the animal was identified were of males, which could be hypothesized as long-range dispersers from Iran. However, the long distances between our records and the nearest known breeding populations in Iran suggests that a so far unnoticed reproducing population nuclei may occur along the north-western part of the Zagros Mountains in western Iran, northern Iraq and south-eastern Turkey.     

Self‐report of physical symptoms associated with using mobile phones and other electrical devices

The aim of our work was to study the working‐age population's self‐reported physical symptoms associated with using mobile phones and other electrical devices. A qualitative method was applied using an open‐ended question in a questionnaire, which included questions about the possible influence of new technical equipment on health. We then created subgroups of respondents for different self‐reported symptoms associated with mobile phones and other electrical devices. The research questions were: (1) how the respondents described physical symptoms associated with using mobile phones and other electrical devices and (2) how the answers can be classified into subgroups based on symptoms or devices. We identified the following categories: (1) respondents with different self‐reported symptoms which they associated with using mobile phones (headache, earache, or warmth sensations), (2) respondents who had skin symptoms when they stayed in front of a computer screen, (3) respondents who mentioned physical symptoms associated with using mobile phones and other electrical devices. Total prevalence of self‐reported physical symptoms associated with using mobile phones and other electrical devices (categories 1 and 2) was 0.7%. In the future it will be possible to obtain new knowledge of these topics by using qualitative methods. Bioelectromagnetics 30:431–437, 2009. © 2009 Wiley‐Liss, Inc.     

Subjective optimality in finite sequential decision-making

Many decisions in life are sequential and constrained by a time window. Although mathematically derived optimal solutions exist, it has been reported that humans often deviate from making optimal choices. Here, we used a secretary problem, a classic example of finite sequential decision-making, and investigated the mechanisms underlying individuals’ suboptimal choices. Across three independent experiments, we found that a dynamic programming model comprising subjective value function explains individuals’ deviations from optimality and predicts the choice behaviors under fewer and more opportunities. We further identified that pupil dilation reflected the levels of decision difficulty and subsequent choices to accept or reject the stimulus at each opportunity. The value sensitivity, a model-based estimate that characterizes each individual’s subjective valuation, correlated with the extent to which individuals’ physiological responses tracked stimuli information. Our results provide model-based and physiological evidence for subjective valuation in finite sequential decision-making, rediscovering human suboptimality in subjectively optimal decision-making processes.     

Coding, recording and incidence of different forms of coronary heart disease in primary care

Objectives

To evaluate the coding, recording and incidence of coronary heart disease (CHD) in primary care electronic medical records.

Methods

Data were drawn from the UK General Practice Research Database. Analyses evaluated the occurrence of 271 READ medical diagnostic codes, including categories for ‘Angina’, ‘Myocardial Infarction’, ‘Coronary Artery Bypass Grafting’ (CABG), ‘percutaneous transluminal coronary angioplasty’ (PCTA) and ‘Other Coronary Heart Disease’. Time-to-event analyses were implemented to evaluate occurrences of different groups of codes after the index date.

Results

Among 300,020 participants aged greater than 30 years there were 75,197 unique occurrences of coronary heart disease codes in 24,244 participants, with 12,495 codes for incident events and 62,702 for prevalent events. Among incident event codes, 3,607 (28.87%) were for angina, 3,262 (26.11%) were for MI, 514 (4.11%) for PCTA, 161 (1.29%) for CABG and 4,951 (39.62%) were for ‘Other CHD’. Among prevalent codes, 20,254 (32.30%) were for angina, 3,644 (5.81%) for MI, 34,542 (55.09%) for ‘Other CHD’ and 4,262 (6.80%) for CABG or PCTA. Among 3,685 participants initially diagnosed exclusively with ‘Other CHD’ codes, 17.1% were recorded with angina within 5 years, 5.6% with myocardial infarction, 6.3% with CABG and 8.6% with PCTA. From 2000 to 2010, the overall incidence of CHD declined, as did the incidence of angina, but the incidence of MI did not change. The frequency of CABG declined, while PCTA increased.

Conclusion

In primary care electronic records, a substantial proportion of coronary heart disease events are recorded with codes that do not distinguish between different clinical presentations of CHD. The results draw attention to the need to improve coding practice in primary care. The results also draw attention to the importance of code selection in research studies and the need for sensitivity analyses using different sets of codes.     

Symptoms of low blood pressure: a population study.

OBJECTIVE--To establish whether an association exists between blood pressures in the "low normal" range and common symptoms such as tiredness, dizziness, headache, and palpitation, as suggested by French and German medical practice but not English or American medical practice. DESIGN--Cross sectional population based survey (the health and lifestyle survey) of blood pressure measurements and self reported common symptoms. Results were analysed by combined stratification and logistic regression. SUBJECTS--7383 (82%) Adults aged 18 and over chosen from the electoral register in England, Wales, and Scotland for the health and lifestyle survey, in whom satisfactory physiological measurements were taken, from 9003 in the interviewed sample. MAIN OUTCOME MEASURES--Body mass index, smoking, social class, exercise, self declared physical illnesses, hours slept, use of drugs, and psychological illness as determined with the general health questionnaire assessed as potential confounders. RESULTS--True confounders were sex, age, taking of drugs, physical illness, exercise, and body mass index. A negative association was found between systolic blood pressure and self reported tiredness and feeling faint, which persisted after adjustment for the confounders. The association was strongest in women aged under 50. A negative association between systolic blood pressure and headache and a positive association between systolic blood pressure and palpitation were explained by confounding by age. CONCLUSIONS--Systemic hypotension is associated with persistent tiredness but treatment is not suggested as either possible or necessary. Instead, low blood pressures may be associated with opposite effects on mortality contrasted with morbidity.
