Assessment of the effects of low dialysate flow rates on removal rates and clearance using high flux membranes.

The effects of the low dialysate flow rates on the removal rate and clearance of urea nitrogen, creatinine, uric acid, beta 2-microglobulin and myoglobin, using high flux membranes were studied. The removal rates for all substances were not significantly decreased. Although clearance of urea nitrogen, creatinine and uric acid was significantly decreased (p < 0.05), clearance of inorganic phosphate, beta 2-microglobulin and myoglobin was not significantly decreased. These results suggest that hemodialysis at low dialysate flow rates for a short term during water shortages due to natural disasters and drier climates can be performed with an insignificant reduction in removal rates and a minimum reduction in clearance.

Psychiatric implications of displacement: contributions from the psychology of place.

OBJECTIVE: The purpose of this article is to describe the psychological processes that are affected by geographic displacement. METHOD: The literature from the fields of geography, psychology, anthropology, and psychiatry was reviewed to develop a "psychology of place" and to determine the manner in which place-related psychological processes are affected by upheaval in the environment. RESULTS: The psychology of place is an emerging area of research that explores the connection between individuals and their intimate environments. The psychology of place posits that individuals require a "good enough" environment in which to live. They are linked to that environment through three key psychological processes: attachment, familiarity, and identity. Place attachment, which parallels, but is distinct from, attachment to person, is a mutual caretaking bond between a person and a beloved place. Familiarity refers to the processes by which people develop detailed cognitive knowledge of their environs. Place identity is concerned with the extraction of a sense of self based on the places in which one passes one's life. Each of these psychological processes-attachment, familiarity, and place identity-is threatened by displacement, and the problems of nostalgia, disorientation, and alienation may ensue. CONCLUSIONS: As a result of war, decolonization, epidemics, natural disasters, and other disruptive events, millions of people are currently displaced from their homes. Protecting and restoring their mental health pose urgent problems for the mental health community.

Preliminary report of psychiatric disorders in survivors of a severe earthquake.

OBJECTIVE: The authors' goal was to study psychiatric morbidity after a natural disaster in rural India. METHOD: As members of a volunteer medical team assigned to 23 households in three villages in India affected by an earthquake, the authors examined the results of semi-structured interviews used to interview all of the adults (older than 14 years) in these households (N=56). DSM-III-R diagnoses were assigned on the basis of these interviews, and non-parametric tests were applied to comparisons of subjects who were or were not given a psychiatric diagnosis. RESULTS: Thirty-three (59%) of the subjects received a psychiatric diagnosis; the most common diagnoses were posttraumatic stress disorder (13 subjects [23%]) and major depression (12 subjects [21%]). Psychiatric morbidity was associated with female sex, destruction of house, and destruction of possessions. CONCLUSIONS: Attention to the mental health needs of disaster survivors in third world countries is indicated.

Postdisaster psychosocial intervention: a field study of the impact of debriefing on psychological distress.

OBJECTIVE: Following a catastrophic natural disaster, the authors evaluated whether brief psychological intervention (debriefing 6 months later) reduced disaster-related psychological distress as measured by the Impact of Event Scale. METHOD: Two groups of subjects who had been exposed to Hurricane Iniki in Hawaii were assessed before and after participating in a multihour debriefing group. The intervention aimed to provide ventilation of feelings, normalization of responses, and education about normal psychological reactions to the disaster in a context of group support. To provide a partial control for the passage of time, the pretreatment assessment of the second group was concurrent with the posttreatment assessment of the first group. RESULTS: A repeated measures analysis of variance indicated that Impact of Event Scale scores were reduced in both groups after the treatment. CONCLUSIONS: There is preliminary empirical support for the effectiveness of postdisaster psychological intervention and for the feasibility of treatment research in postdisaster environments.

Genetic and environmental influences on trauma exposure and posttraumatic stress disorder symptoms: a twin study.

OBJECTIVE: Posttraumatic stress disorder (PTSD) develops in only a subset of persons exposed to traumatic stress, suggesting the existence of stressor and individual differences that influence risk. In this study the authors examined the heritability of trauma exposure and PTSD symptoms in male and female twin pairs of nonveteran volunteers. METHOD: Scores on a traumatic events inventory and a DSM-IV PTSD symptom inventory were examined in 222 monozygotic and 184 dizygotic twin pairs. Biometrical model fitting was conducted by using standard statistical methods. RESULTS: Additive genetic, common environmental, and unique environmental effects best explained the variance in exposure to assaultive trauma (e.g., robbery, sexual assault), whereas exposure to nonassaultive trauma (e.g., motor vehicle accident, natural disaster) was best explained by common and unique environmental influences. PTSD symptoms were moderately heritable, and the remaining variance was accounted for by unique environmental experiences. Correlations between genetic effects on assaultive trauma exposure and on PTSD symptoms were high. CONCLUSIONS: Genetic factors can influence the risk of exposure to some forms of trauma, perhaps through individual differences in personality that influence environmental choices. Consistent with symptoms in combat veterans, PTSD symptoms after noncombat trauma are also moderately heritable. Moreover, many of the same genes that influence exposure to assaultive trauma appear to influence susceptibility to PTSD symptoms in their wake.

Use of mental health services after hurricane Floyd in North Carolina.

OBJECTIVE: The aim of this study was to examine the impact of a natural disaster, Hurricane Floyd, on the use of mental health services in a Medicaid population in North Carolina. METHODS: Difference-in-differences techniques were used to determine month-by-month and 12-month postevent average effects of the hurricane on the use of mental health services at the county level. The exposure group was drawn from 14 severely affected counties, and the control group was drawn from 56 unaffected counties. Data were analyzed from July 1998 (14 months before the hurricane) to September 2000 (12 months after the hurricane). RESULTS: The number of per-enrollee per-month outpatient visits to psychologists or licensed clinical social workers and the number of outpatient visits to non-mental health specialists showed a statistically significant increase over the 12-month postevent period, whereas the number of inpatient admissions for behavioral health reasons decreased. Dollars spent on antianxiety medication per enrollee per month showed a statistically significant decrease. CONCLUSIONS: The aftermath of Hurricane Floyd was associated with significantly greater use of mental health services in the Medicaid community in North Carolina for a few services. However, it is unclear whether changes in utilization patterns were due to the greater demand for services or to the availability of other services that may have served as substitutes. The results of this study underscore the importance of planning for service implementation and delivery after similar events in other states.

The 1999 Ji-Ji (Taiwan) earthquake as a trigger for acute myocardial infarction.

The authors evaluated the effect of stress due to the Ji-Ji, Taiwan, earthquake, which occurred at 1:47 a.m. on September 21, 1999, on the onset of acute myocardial infarction in six counties near the earthquake epicenter. The rate of hospitalization due to acute myocardial infarction increased during the 6 weeks after the earthquake, and a significantly higher number of patients were hospitalized with acute myocardial infarction during that period, compared with the same 6-week period in the previous year (99 and 65 patients, respectively). The findings suggest that extreme emotional stress due to the natural disaster, superimposed on the stress of awakening, increased the incidence of acute myocardial infarction in this population.

Crisis debriefing of a jury after a murder trial.

The importance of crisis debriefing for those involved in major accidents, violent crimes, and natural disasters has been demonstrated. Similar debriefing may be warranted for jurors exposed to disturbing material in criminal cases. The authors describe a debriefing session for jurors after the murder trial of a man whose truck had collided with a school bus, killing 27 people. The graphic evidence of the accident, the high levels of emotion of the survivors and the victims' relatives, and the intense community and national attention to the trial placed the jurors under considerable stress. The debriefing enabled the jurors to express their feelings of anger, guilt, and frustration and to begin to accept their role in the event.

The survivor syndrome: further observations and dimensions.

Clinical experience over three and a half decades in the evaluation, diagnosis and treatment of close to 2000 concentration camp survivors indicates that we are dealing with a type of massive traumatization of such magnitude and severity as to cause a recognizable clinical entity I have named "the survivor syndrome," which develops irrespective of age, sex, and individual or sociocultural background. The clinical symptoms and characteristic features of this syndrome are described in some detail. The condition is chronic, in many cases severe, and presents unique difficulties to both patient and therapist. The influence of the psychic disturbances on the offspring is frequent and notable. Further research on the syndrome and comparative studies on its occurrence in survivors of natural disasters is suggested. But one fact can be stated with certainty: The effects of the holocaust on the survivors linger on.

Emotional and somatic distress in eastern North Carolina: help-seeking behaviors.

Socio-demographic and cultural factors have been reported to shape help-seeking behavior. However, not much effort has been made to determine the effects of these factors on help-seeking among rural populations. A telephone survey using random-digit dialing was used to explore socio-demographic characteristics and ethnic differences in the types of professionals sought for unexplained somatic and emotional problems (N = 1161) in rural eastern North Carolina. Ethnic differences in comfort with participating in support groups were also examined. The effect of a large natural disaster, Hurricane Floyd and subsequent flooding, on help-seeking choices and comfort with support groups was also assessed. Results showed that the rural population makes a sharp distinction between somatic symptoms and stress-related symptoms. This distinction seemed more pronounced for European-Americans than for African-Americans. In general African-Americans selected help-seeking from clergy more often than European-Americans, although for unexplained somatic symptoms this difference was fostered by Hurricane Floyd with its flooding. African-Americans showed markedly increased comfort with support groups after the hurricane, while European-Americans showed no changes in comfort with support groups as a function of the hurricane. The effects of Hurricane Floyd on African-Americans are interpreted as reflecting an increased salience of community support for African-Americans, significantly through the Baptist Church. Training of clergy should include recognition of stress-related somatic and emotional symptoms and the potential for an important referral role, especially following disasters.

Osmotic production of sterile oral rehydration solutions--an economic, low-technology method.

A sterile oral rehydration solution can be produced by immersing in water a semi-permeable cellulose tube containing glucose and salts. Osmotically-driven ultrafiltration excludes all microbes and particulate matter even when the immersion water contains 45 x 10(6) cfu/ml of Pseudomonas aeruginosa, 25 x 10(7) cfu/ml of Staphylococcus aureus or 20 x 10(7) cfu/ml of Escherichia coli. Solutions of consistent composition can be obtained by having a standard amount of glucose-electrolytes in a cellulose tube of appropriate dimensions and immersing this in a fixed volume of water for a minimum period of time. The method is simple, inexpensive, low-technology and requires no external source of power. It has potential for producing sterile solutions for injections and intravenous use in situations with very limited and simple resources, in emergencies and during natural disasters. Further studies are now needed to determine whether the method can be adapted to provide the large quantities of oral rehydration fluid needed in field conditions.

Validation of a French version of the impact of event scale-revised.

OBJECTIVE: This report presents a French translation and validation of the Impact of Event Scale-Revised (IES-R) in a population of women exposed to a natural disaster during or preceding pregnancy. METHOD: A total of 223 francophone women who were either pregnant at the time of the 1998 ice storm or who became pregnant shortly thereafter completed the IES-R and other questionnaires 6 months after the disaster. RESULTS: The French IES-R has good internal consistency, with alpha coefficients ranging from 0.81 to 0.93 for its 3 subscales and total score. The test-retest reliability of the scale, although examined with another sample, proved to be satisfactory, with correlation coefficients ranging from 0.71 to 0.76 for its 3 subscales and total score. Its convergent validity with perceived life threat and general psychiatric symptoms was judged to be marginally acceptable. Finally, a principal components analysis was conducted and a 3-factor solution, which explained 56% of the variance, was retained: a hyperarousal factor (7 items), an avoidance factor (6 items), and an intrusion factor (6 items). CONCLUSIONS: The French version of the IES-R has satisfactory internal validity and test-retest reliability. Further, the factor structure of the translation was similar to the proposed theoretical structure of the IES-R.

Therapeutic touch and post-Hurricane Hugo stress.

This repeated-session design sought to answer questions about the effectiveness of therapeutic touch in reduction of stress for 23 individuals following a natural disaster. In addition, methodological issues related to the average length of time for a therapeutic-touch treatment and a method of documenting the nonverbal interaction between subject and toucher were investigated. Findings indicate that stressed people report themselves to be less stressed following therapeutic touch (p = .05). Time of therapeutic-touch intervention varied significantly between the touchers, with a range of 6.8 to 20 minutes. Qualitative data examining the interaction of toucher and subject raised a number of questions that require further study.

Redtide in the Philippines.

1. Redtide is a marine phenomenon that poses great risk to the health and economic livelihood of people in coastal areas. Paralytic shellfish poisoning develops when a person consumes molluscs containing toxic dinoflagellates and suffers neurological and/or gastrointestinal manifestations. 2. Four redtide incidents in the Philippines are presented. The manner in which the problems were managed are described. 3. The clinical features of redtide poisoning in the Philippines included gastro-intestinal and neurological features with deaths secondary to ventilatory failure. Mortality ranged from 0% to 12% in the different redtide episodes. 4. There are many lessons to be learned in handling this kind of natural disaster. For an effective toxicovigilance programme, there must be a central co-ordinating responsible organization, a clear definition of roles and functions and good inter-agency co-operation. Appropriate surveillance procedures, resources to intensify surveillance at times of risks, prompt warning system, and the ability to impose bans on consumption are also necessary. 5. Poisons centres can play an important role during times of redtide. This may include toxicovigilant activities, such as early warning and educational campaigns to consumers, and seminars in the recognition and management of paralytic shellfish poisoning. 6. The contribution of the epidemiologists in investigating and monitoring the extent of public health damage and patterns of poisoning in a coastal community is emphasized.

Mediators of the Association Between a Parent's Experience of Trauma and Their Children's Well-Being: A Systematic Review.

At present, our understanding of trauma's complexity is underdeveloped, particularly with regard to intergenerational effects. In this paper, we review peer-reviewed literature on parental trauma and child well-being, focusing on mediating factors. We conducted a global systematic review of longitudinal, observational studies assessing mediators between a parent's traumatic exposure and their children's well-being. The primary outcome of the review was quantitative measures of child well-being (physical and psycho-social) assessed when the child was 18 years or under. We considered the following experiences as trauma exposures: intimate partner violence, rape, sexual assault, victimization during violent crime, childhood abuse, and exposure to direct, immediate threats to personal survival during war, political unrest, natural disasters, and sudden, critical injury/illness. Thirty-two studies met our inclusion criteria. The two most common mediator categories were caregiver mental health (n = 13) and parenting behavior (n = 10). Other studies measured aspects of the parent-child relationship (n = 9), maternal stress factors (n = 5), parental physical health (n = 2), and child-level factors (n = 6) as mediators. Almost all included studies (n = 28) detected a mediation effect. The majority of studies (n = 21) cited robust theoretical frameworks to support their mediator and outcome choices. Studies varied in quality, but most used appropriate, formal mediation analyses. Several study designs could be enhanced by methods to improve precision and reduce bias. Currently, there is little consistency in how similar constructs are measured between mediation studies. We did not locate any studies in low-income countries, and few studies examined aspects of family dynamics, physical health, environmental characteristics, or paternal factors.

Food for nutrition: mainstreaming nutrition in WFP.

Most preventable deaths among hungry people take place outside of emergency contexts. In countries not involved in conflicts or natural disasters malnutrition is directly implicated in the deaths of millions of children and mothers each year. Thus, WFP's great efforts focused on saving lives in emergencies should be mirrored by efforts aimed at tackling malnutrition, and hence saving lives, beyond emergencies as well. While food sufficiency is not the same as good nutrition, food is nevertheless an important part of the nutrition equation. New scientific evidence confirms that it is possible to have positive nutritional impacts with food aid. Consistent with Strategic Priority No. 3, WFP seeks to use food resources to achieve nutritional impacts in three complementary ways: a) enhancing the effectiveness and impact of targeted mother and child health and nutrition interventions (MCHN) that combine food and appropriate nonfood inputs; b) enhancing the nutritional value of WFP food (for instance, through micronutrient fortification); and c) enhancing the nutritional impact of other WFP (non-MCHN) interventions. These approaches represent a mainstreaming of nutrition across WFP's activities. Adoption of evidence-based programming, joint interventions with partners, and new project designs offer the promise of greater WFP effectiveness and impact in the coming years.

Globalisation, complex humanitarian emergencies and health.

A new political economy of conflict has emerged in the aftermath of colonialism and the Cold War. Complex political emergencies have been simmering in the post-colonial world for more than three decades. Intra-country armed conflict, often combined with natural disasters, at present contributes to the displacement of over 20 million people world-wide. The international community remains profoundly uncomfortable with the complex political emergencies of the new era, torn between the respect for national sovereignty upon which the international political system of the United Nations and other agencies is built, and the growth of concern with human rights and a burgeoning International Humanitarian Law. Globalisation may have brought many benefits to some but there are also many losers. The Word Bank and the International Monetary Fund imposed structural adjustment policies to ensure debt repayment and economic restructuring that have resulted in a net reduction in expenditure on health, education and development. A downward spiral has been created of debt, disease, malnutrition, missed education, economic entrapment, poverty, powerlessness, marginalization, migration and instability. Africa's complex political emergencies are particularly virulent and tenacious. Three examples that are among the most serious humanitarian emergencies to have faced the world in recent times--those in Angola, the Democratic Republic of Congo and Sudan--are reviewed here in detail. The political evolution of these emergencies and their impact on the health of the affected populations are also explored.

Business and public health collaboration for emergency preparedness in Georgia: a case study.

BACKGROUND: Governments may be overwhelmed by a large-scale public health emergency, such as a massive bioterrorist attack or natural disaster, requiring collaboration with businesses and other community partners to respond effectively. In Georgia, public health officials and members of the Business Executives for National Security have successfully collaborated to develop and test procedures for dispensing medications from the Strategic National Stockpile. Lessons learned from this collaboration should be useful to other public health and business leaders interested in developing similar partnerships. METHODS: The authors conducted a case study based on interviews with 26 government, business, and academic participants in this collaboration. RESULTS: The partnership is based on shared objectives to protect public health and assure community cohesion in the wake of a large-scale disaster, on the recognition that acting alone neither public health agencies nor businesses are likely to manage such a response successfully, and on the realization that business and community continuity are intertwined. The partnership has required participants to acknowledge and address multiple challenges, including differences in business and government cultures and operational constraints, such as concerns about the confidentiality of shared information, liability, and the limits of volunteerism. The partnership has been facilitated by a business model based on defining shared objectives, identifying mutual needs and vulnerabilities, developing carefully-defined projects, and evaluating proposed project methods through exercise testing. Through collaborative engagement in progressively more complex projects, increasing trust and understanding have enabled the partners to make significant progress in addressing these challenges. CONCLUSION: As a result of this partnership, essential relationships have been established, substantial private resources and capabilities have been engaged in government preparedness programs, and a model for collaborative, emergency mass dispensing of pharmaceuticals has been developed, tested, and slated for expansion. The lessons learned from this collaboration in Georgia should be considered by other government and business leaders seeking to develop similar partnerships.
