1.  Hurricane Katrina’s Impact on the Mental Health of Adolescent Female Offenders 
Anxiety, stress, and coping  2009;22(4):433-448.
Exposure to multiple traumatic events and high rates of mental health problems are common among juvenile offenders. This study draws on Conservation of Resources (COR) stress theory to examine the impact of a specific trauma, Hurricane Katrina, relative to other adverse life events on the mental health of female adolescent offenders in Mississippi. Teenage girls (N = 258, 69% African American) were recruited from 4 juvenile detention centers and the state training school. Participants were interviewed about the occurrence and timing of adverse life events and hurricane-related experiences and completed a self-administered mental health assessment. Hierarchical linear regression models were used to identify predictors of anxiety and depression. Pre-hurricane family stressors, pre-hurricane traumatic events, hurricane-related property damage, and receipt of hurricane-related financial assistance significantly predicted symptoms of anxiety and depression. Findings support COR theory. Family stressors had the greatest influence on symptoms of anxiety and depression, highlighting the need for family-based services that address the multiple, inter-related problems and challenges in the lives of female juvenile offenders.

2.  Implementation of Evidence-based Asthma Interventions in Post-Katrina New Orleans: The Head-off Environmental Asthma in Louisiana (HEAL) Study 
Environmental Health Perspectives  2012;120(11):1607-1612.
Background: Childhood asthma morbidity and mortality in New Orleans, Louisiana, is among the highest in the nation. In August 2005, Hurricane Katrina created an environmental disaster that led to high levels of mold and other allergens and disrupted health care for children with asthma.
Objectives: We implemented a unique hybrid asthma counselor and environmental intervention based on successful National Institutes of Health asthma interventions from the National Cooperative Inner City Asthma (NCICAS) and Inner-City Asthma (ICAS) Studies with the goal of reducing asthma symptoms in New Orleans children after Hurricane Katrina.
Methods: Children (4–12 years old) with moderate-to-severe asthma (n = 182) received asthma counseling and environmental intervention for approximately 1 year. HEAL was evaluated employing several analytical approaches including a pre–post evaluation of symptom changes over the entire year, an analysis of symptoms according to the timing of asthma counselor contact, and a comparison to previous evidence-based interventions.
Results: Asthma symptoms during the previous 2 weeks decreased from 6.5 days at enrollment to 3.6 days at the 12-month symptom assessment (a 45% reduction, p < 0.001), consistent with changes observed after NCICAS and ICAS interventions (35% and 62% reductions in symptom days, respectively). Children whose families had contact with a HEAL asthma counselor by 6 months showed a 4.09-day decrease [95% confidence interval (CI): 3.25 to 4.94-day decrease] in symptom days, compared with a 1.79-day decrease (95% CI: 0.90, 2.67) among those who had not yet seen an asthma counselor (p < 0.001).
Conclusions: The novel combination of evidence-based asthma interventions was associated with improved asthma symptoms among children in post-Katrina New Orleans. Post-intervention changes in symptoms were consistent with previous randomized trials of NCICAS and ICAS interventions.

3.  Depressive Symptoms among Firefighters and Related Factors after the Response to Hurricane Katrina 
Journal of Urban Health   2007;84(2):153-161.
The National Institute for Occupational Safety and Health conducted an evaluation regarding physical and psychological health symptoms among New Orleans firefighters 13 weeks after Hurricane Katrina struck the U.S. Gulf Coast on August 29, 2005. This report examines associations between depressive symptoms and concurrent comorbidity. Depressive symptoms were twice as likely among those with either lower respiratory symptoms or skin rash. Firefighters housed with their families were less likely to report depressive symptoms compared to those not living with their families. Perceived low supervisor support was associated with depressive symptoms, whereas participating in group counseling was not. The results underscore the need for the incorporation of physical and psychological health follow-up of emergency responders after natural disasters to better understand, monitor, and treat their health conditions.

4.  The Relationship between Mold Exposure and Allergic Response in Post-Katrina New Orleans 
Journal of Allergy  2010;2010:510380.
Objectives. The study's objective was to examine the relation between mold/dampness exposure and mold sensitization among residents of Greater New Orleans following Hurricane Katrina. Methods. Patients were recruited from the Allergy Clinic of a major medical facility. Any patient receiving a skin prick test for one of 24 molds between December 1, 2005 and December 31, 2008 was eligible for the study. Exposure was assessed using standardized questionnaires. Positive mold reactivity was defined as a wheal diameter >3 mm to any mold genera. Results. Approximately 57% of participants tested positive to any indoor allergen, 10% to any mold. Over half of respondents had significant home damage, 34% reported dampness/mold in their home, half engaged in renovation, and one-third lived in a home undergoing renovation. Despite extensive exposure, and multiple measures of exposure, we found no relationship between mold/dampness exposure and sensitivity to mold allergens. Conclusions. These results along with results of earlier research indicate no excess risk of adverse respiratory effects for residents living in New Orleans after the devastation of Hurricane Katrina.

5.  Five Years Later: Recovery from Post Traumatic Stress and Psychological Distress Among Low-Income Mothers Affected by Hurricane Katrina 
Social science & medicine (1982)  2011;74(2):150-157.
Hurricane Katrina, which struck the Gulf Coast of the United States in August 2005, exposed area residents to trauma and extensive property loss. However, little is known about the long-run effects of the hurricane on the mental health of those who were exposed. This study documents long-run changes in mental health among a particularly vulnerable group—low income mothers—from before to after the hurricane, and identifies factors that are associated with different recovery trajectories. Longitudinal surveys of 532 low-income mothers from New Orleans were conducted approximately one year before, 7 to 19 months after, and 43 to 54 months after Hurricane Katrina. The surveys collected information on mental health, social support, earnings and hurricane experiences. We document changes in post-traumatic stress symptoms (PTSS), as measured by the Impact of Event Scale-Revised, and symptoms of psychological distress (PD), as measured by the K6 scale. We find that although PTSS has declined over time after the hurricane, it remained high 43 to 54 months later. PD also declined, but did not return to pre-hurricane levels. At both time periods, psychological distress before the hurricane, hurricane-related home damage, and exposure to traumatic events were associated with PTSS that co-occurred with PD. Hurricane-related home damage and traumatic events were associated with PTSS without PD. Home damage was an especially important predictor of chronic PTSS, with and without PD. Most hurricane stressors did not have strong associations with PD alone over the short or long run. Over the long run, higher earnings were protective against PD, and greater social support was protective against PTSS. These results indicate that mental health problems, particularly PTSS alone or in co-occurrence with PD, among Hurricane Katrina survivors remain a concern, especially for those who experienced hurricane-related trauma and had poor mental health or low socioeconomic status before the hurricane.

6.  Alcohol and Cigarette Use and Misuse among Hurricane Katrina Survivors: Psychosocial Risk and Protective Factors 
Substance use & misuse  2009;44(12):1711-1724.
The present study examined survivors’ use and misuse of cigarettes and alcohol following Hurricane Katrina. We also examined several psychosocial factors that we expected would be associated with higher or lower rates of substance use following the Hurricane. Participants were 209 adult survivors of Hurricane Katrina interviewed in Columbia, SC or New Orleans, LA between October 31, 2005 and May 13, 2006. Results revealed that survivors were smoking cigarettes, consuming alcohol, and experiencing alcohol-related problems at a substantially higher rate than expected based on pre-Hurricane prevalence data. Results also suggested that certain psychosocial factors were associated with participants’ substance use and misuse following the Hurricane.

7.  The Psychological Impact From Hurricane Katrina: Effects of Displacement and Trauma Exposure on University Students 
Behavior Therapy  2010;41(3):340-349.
The following study examined the reactions of university students to Hurricane Katrina. A group of 68 New Orleans area students who were displaced from their home universities as a result of the hurricane were matched on race, gender, and age to a sample of 68 students who had been enrolled at Louisiana State University (LSU) prior to the hurricane. All students were enrolled at LSU at the time they participated in an online survey, conducted 3 months following the hurricane. The survey included symptom measures of depression, anxiety, stress, posttraumatic stress disorder (PTSD), and other variables. Results indicated displaced students experienced more trauma exposure and greater subsequent distress, more symptoms of PTSD, and more symptoms of depression. Moreover, traumatic exposure and distress from the traumatic exposure were found to fully mediate depressive symptoms and posttraumatic symptoms in the displaced students.

8.  Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina 
Journal of Urban Health   2007;84(2):142-152.
On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from the largest employer in New Orleans. The prevalence of PTSD symptoms was 19.2%. Predictors of PTSD symptoms in a multivariate-adjusted regression model included female sex, non-black race, knowing someone who died in the storm, not having property insurance, having had a longer evacuation, a much longer work commute compared to before Hurricane Katrina, and currently living in a newly purchased or rented house or in a temporary trailer. Despite universal health coverage and the benefits of an employee assistance program for all employees, only 28.5% of those with PTSD symptoms had talked to a health professional about the events of Hurricane Katrina or issues encountered since the storm. A significant burden of PTSD symptoms was present 6 months following Hurricane Katrina among a large group of adults who had returned to work in New Orleans. Given their key role in the economic redevelopment of the region, there is a tremendous need to identify those in the workforce with symptoms consistent with PTSD and to enhance treatment options. The strong relationship between displacement from ones’ pre-Katrina residence and symptoms of PTSD suggests a need to focus resource utilization and interventions on individuals living in temporary housing.

9.  Children’s Mental Health Care following Hurricane Katrina: A Field Trial of Trauma-Focused Psychotherapies 
Journal of traumatic stress  2010;23(2):223-231.
New Orleans school children participated in an assessment and field trial of two interventions 15 months after Hurricane Katrina. Children (N = 195) reported on hurricane exposure, lifetime trauma exposure, peer and parent support, posttraumatic stress disorder (PTSD), and depressive symptoms. Teachers reported on behavior. At baseline, 60.5% screened positive for PTSD symptoms and were offered a group intervention at school or individual treatment at a mental health clinic. Uptake of the mental health care was uneven across intervention groups, with 98% beginning the school intervention, compared to 37% beginning at the clinic. Both treatments led to significant symptom reduction of PTSD symptoms but many still had elevated PTSD symptoms at post treatment. Implications for future postdisaster mental health work are discussed.

10.  Exposure to Hurricane Katrina, Post-Traumatic Stress Disorder and Birth Outcomes 
Little is known about the effects of natural disasters on pregnancy outcomes. We studied mental health and birth outcomes among women exposed to Hurricane Katrina.
We collected data prospectively from a cohort of 301 women from New Orleans and Baton Rouge. Pregnant women were interviewed during pregnancy about their experiences during the hurricane, as well as whether they had experienced symptoms of post-traumatic stress disorder (PTSD) and/or depression. High hurricane exposure was defined as having three or more of the eight severe hurricane experiences, such as feeling that one's life was in danger, walking through floodwaters, or having a loved one die.
The frequency of low birth weight was higher in women with high hurricane exposure (14.0%) than women without high hurricane exposure (4.7%), with an adjusted odds ratio (aOR): 3.3; 95% confidence interval (CI): 1.13−9.89; p<0.01. The frequency of preterm birth was higher in women with high hurricane exposure (14.0%) than women without high hurricane exposure (6.3%), with aOR: 2.3; 95% CI: 0.82−6.38; p>0.05. There were no significant differences in the frequency of low birth weight or preterm birth between women with PTSD or depression and women without PTSD or depression (p>0.05).
Women who had high hurricane exposure were at an increased risk of having low birth weight infants. Rather than a general exposure to disaster, exposure to specific severe disaster events and the intensity of the disaster experience may be better predictors of poor pregnancy outcomes. To prevent poor pregnancy outcomes during and after disasters, future disaster preparedness may need to include the planning of earlier evacuation of pregnant women to minimize their exposure to severe disaster events.

11.  A Test of the Family Stress Model on Toddler-Aged Children’s Adjustment Among Hurricane Katrina Impacted and Nonimpacted Low-Income Families 
Hurricane Katrina dramatically altered the level of social and environmental stressors for the residents of the New Orleans area. The Family Stress Model describes a process whereby felt financial strain undermines parents’ mental health, the quality of family relationships, and child adjustment. Our study considered the extent to which the Family Stress Model explained toddler-aged adjustment among Hurricane Katrina affected and nonaffected families. Two groups of very low-income mothers and their 2-year-old children participated (pre-Katrina, n = 55; post-Katrina, n = 47). Consistent with the Family Stress Model, financial strain and neighborhood violence were associated with higher levels of mothers’ depressed mood; depressed mood was linked to less parenting efficacy. Poor parenting efficacy was associated to more child internalizing and externalizing problems.

12.  Respiratory Health Effects Associated with Restoration Work in Post-Hurricane Katrina New Orleans 
Background. This study examines prevalence of respiratory conditions in New Orleans-area restoration workers after Hurricane Katrina. Methods. Between 2007 and 2010, spirometry and respiratory health and occupational questionnaire were administered to 791 New Orleans-area adults who mostly worked in the building construction and maintenance trades or custodial services. The associations between restoration work hours and lung function and prevalence of respiratory symptoms were examined by multiple linear regression, χ2, or multiple logistic regression. Results. 74% of participants performed post-Katrina restoration work (median time: 620 hours). Symptoms reported include episodes of transient fever/cough (29%), sinus symptoms (48%), pneumonia (3.7%), and new onset asthma (4.5%). Prevalence rate ratios for post-Katrina sinus symptoms (PRR = 1.3; CI: 1.1, 1.7) and fever and cough (PRR = 1.7; CI: 1.3, 2.4) were significantly elevated overall for those who did restoration work and prevalence increased with restoration work hours. Prevalence rate ratios with restoration work were also elevated for new onset asthma (PRR = 2.2; CI: 0.8, 6.2) and pneumonia (PRR = 1.3; CI: 0.5, 3.2) but were not statistically significant. Overall, lung function was slightly depressed but was not significantly different between those with and without restoration work exposure. Conclusions. Post-Katrina restoration work is associated with moderate adverse effects on respiratory health, including sinusitis and toxic pneumonitis.

13.  Hurricane Katrina Experience and the Risk of Post-Traumatic Stress Disorder and Depression among Pregnant Women 
Little is known about the effects of disaster exposure and intensity on the development of mental disorders among pregnant women. The aim of this study was to examine the effect of exposure to Hurricane Katrina on mental health in pregnant women.
Prospective cohort epidemiological study.
Tertiary hospitals in New Orleans and Baton Rouge, USA.
Women who were pregnant during Hurricane Katrina or became pregnant immediately after the hurricane.
Main outcome measures
Post-traumatic stress disorder (PTSD) and depression.
The frequency of PTSD was higher in women with high hurricane exposure (13.8%) than women without high hurricane exposure (1.3%), with an adjusted odds ratio (aOR) of 16.8; 95 % confidence interval (CI): 2.6-106.6; after adjustment for maternal race, age, education, smoking and alcohol use, family income, parity, and other confounders. The frequency of depression was higher in women with high hurricane exposure (32.3%) than women without high hurricane exposure (12.3%), with aOR of 3.3 (1.6-7.1). Moreover, the risk of PTSD and depression increased with an increasing number of severe experiences of the hurricane.
Pregnant women who had severe hurricane experiences were at a significantly increased risk for PTSD and depression. This information should be useful for screening pregnant women who are at higher risk of developing mental disorders after disaster.

14.  Treating Traumatized Children after Hurricane Katrina: Project Fleur-de Lis™ 
Project Fleur-de-lis™ (PFDL) was established to provide a tiered approach to triage and treat children experiencing trauma symptoms after Hurricane Katrina. PFDL provides school screening in schools in New Orleans and three tiers of evidence-based treatment (EBT) to disaster-exposed children. Utilizing a public health approach to meet the various needs of students referred to the program, some stemming from the disaster itself, some related to prior exposure to violence, and some relating to preexisting conditions and educational delays. The National Institute of Mental Health (NIMH) is funding a research project conducted in collaboration with PFDL, to examine two evidence-based practices for child PTSD in order to guide child treatment decisions after future disaster situations. The present paper describes the need for mental health services for children following disaster, the structure and purpose of PFDL, design of the NIMH project, two case descriptions of children treated within the project, and preliminary lessons learned.

15.  PTSD in Vietnamese Americans Following Hurricane Katrina: Prevalence, Patterns, and Predictors 
Journal of traumatic stress  2009;22(2):91-101.
One year after Hurricane Katrina devastated New Orleans, we assessed 82 adults from a population-based sample of the Vietnamese American community who had participated in a larger study of immigration weeks before the disaster. Although 21% met criteria for partial PTSD, only 5% of the sample met all PTSD criteria. Avoidance/numbing symptoms did not form a coherent cluster and were seldom confirmed, but intrusion, arousal, and interference were common. Severity of exposure to the flood waters, property loss, and subjective trauma were independently related to PTSD symptoms. Symptoms were highest among participants who were low in acculturation or who had high Katrina exposure in combination with prolonged stays in transition camps during emigration.

Hurricane Katrina accomplished what no law enforcement initiative could ever achieve: It completely eradicated the New Orleans drug market. However, Katrina did little to eliminate the demand for drugs. This article documents the process of the drug market reconstitution that occurred 2005–2008 based on in-depth interviews and focus groups with predominately low-income drug users and sellers. Before Katrina, the drug market was largely characterized by socially-bonded participants involved with corporate style distribution. After Katrina, a violent freelance market emerged. The conclusion draws recommendations for law enforcement for dealing with drug markets after a major disaster.
This article uses New Orleans as a case study to chart the process of drug market reconstitution following an extreme disaster, namely Hurricane Katrina. On August 29, 2005, Hurricane Katrina made landfall and engulfed the New Orleans area, overwhelming levees and causing extensive flooding and destruction across the city. The storm generated 30- to 40-foot waves, which demolished many cities and small towns in Southern Mississippi and Alabama and caused considerable wind damage further inland. Although the hurricane eye missed central New Orleans by about 30 miles, the wave action in Lake Pontchartrain caused several levees to break and flood most of eastern New Orleans, which was under sea level. The storm had an impact on practically all New Orleans residents and almost destroyed New Orleans (Cooper & Block, 2006; Levitt & Whitaker, 2009; Lee, 2006).
Our research focused on the impact of this storm on the drug markets in New Orleans. Katrina destroyed the physical environment and organizational structure that sustained the drug trade, yet drug use and sales did not disappear. During and soon after the storm, improvised sales and distribution organizations provided a wide range of illicit drugs to users (see Dunlap, Johnson, Kotarba, & Fackler, 2009; Dunlap & Golub, 2010; Dunlap, Johnson & Morse, 2007). This article examines the next historical period, the continuation of drug use among those returning to New Orleans and the rebuilding of drug market structures. The analysis provides a short review of drug markets before Katrina. Our main focus is the reconstitution process during the three years following the disaster. We pay special attention to street-level dealers and the end users’ lived experiences in primarily poorer neighborhoods, illustrating elements of continuity and change as various actors reconstituted New Orleans’ drug market.

17.  Patterns of substance use among Hurricane Katrina evacuees in Houston, Texas 
Disasters  2009;34(2):426-446.
This paper focuses on changing patterns of substance use among low income, African American drug users evacuated from New Orleans, Louisiana, during Hurricane Katrina of August 2005. It examines the relationship between increases and decreases in alcohol and tobacco (AT) use and illicit drug (ID) use after Katrina and pre-disaster and within-disaster factors. Data from structured interviews with 200 Katrina evacuees currently living in Houston were collected 8–14 months after the disaster. Multivariate analysis revealed that rises in AT use were positively associated with education. Females and younger evacuees were more likely to have increased AT use. ID use increase was positively associated with resource loss and leaving the city before Katrina. Decreases in AT and ID use were found to be associated with disaster-related exposure. The paper discusses the specific consequences of disasters on disadvantaged minority substance users and the importance of developing public health disaster policies that target this population.

18.  Disparities in health care among Vietnamese New Orleanians and the impacts of Hurricane Katrina 
This paper examines the use of routine health care and disparities by socio-economic status among Vietnamese New Orleanians. It also assesses how these differences may have changed as the result of Hurricane Katrina, which struck the Gulf Coast in late summer 2005, devastating the infrastructure of the health care system of New Orleans. Data for this study come from a panel of Vietnamese New Orleanians who were interviewed in 2005, just weeks before the hurricane, and followed up twice near the disaster’s anniversary in 2006 and 2007. Findings show a steep declining trend in routine health care after the hurricane, compared to 2005. Marked differences in health care were already apparent in 2005 (before Katrina) between education levels, home ownership, and health insurance coverage. These differences were significantly reduced one year after the hurricane. We argue, however, that the reduction in disparities was not due to improved health care services or improved health care practice. Instead, it was likely due to the influx of free health care services that were provided to meet urgent needs of hurricane survivors while the area’s infrastructure was devastated. By 2007, these free health care services were no longer widely available. Routine health visits dropped further and the temporary reduction in disparities disappeared. The paper also underlines ongoing shortages of essential health care services for Vietnamese New Orleanians. Efforts need to ensure that all members of this community receive the full array of comprehensive and culturally-appropriate health care as they continue to rebuild from the Katrina disaster.

19.  Indoor Environmental Exposures for Children with Asthma Enrolled in the HEAL Study, Post-Katrina New Orleans 
Environmental Health Perspectives  2012;120(11):1600-1606.
Background: Rain and flooding from Hurricane Katrina resulted in widespread growth of mold and bacteria and production of allergens in New Orleans, Louisiana, which may have led to increased exposures and morbidity in children with asthma.
Objectives: The goal of the Head-off Environmental Asthma in Louisiana (HEAL) study was to characterize post-Katrina exposures to mold and allergens in children with asthma.
Methods: The homes of 182 children with asthma in New Orleans and surrounding parishes were evaluated by visual inspection, temperature and moisture measurements, and air and dust sampling. Air was collected using vacuum-pump spore traps and analyzed for > 30 mold taxa using bright field microscopy. Dust was collected from the children’s beds and bedroom floors and analyzed for mouse (Mus m 1), dust mite (Der p 1), cockroach (Bla g 1), and mold (Alternaria mix) allergens using ELISA.
Results: More than half (62%) of the children were living in homes that had been damaged by rain, flooding, or both. Geometric mean indoor and outdoor airborne mold levels were 501 and 3,958 spores/m3, respectively. Alternaria antigen was detected in dust from 98% of homes, with 58% having concentrations > 10 µg/g. Mus m 1, Der p 1, and Bla g 1 were detected in 60%, 35%, and 20% of homes, respectively, at low mean concentrations.
Conclusions: Except for Alternaria antigen in dust, concentrations of airborne mold (ratio of indoor to outdoor mold) and dust allergens in the homes of HEAL children were lower than measurements found in other studies, possibly because of extensive post-Katrina mold remediation and renovations, or because children moved into cleaner homes upon returning to New Orleans.

20.  Quality of Life in Hypertensive Clinic Patients Following Hurricane Katrina 
The Ochsner Journal  2011;11(3):226-231.
The purpose of this study was to assess quality of life among hypertensive patients in the year following Hurricane Katrina.
Hypertensive patients (n  =  211) in a multispecialty group practice in New Orleans completed validated surveys during the year after Hurricane Katrina. We assessed patients' demographics, quality of life (Medical Outcomes Study 36), hurricane coping self-efficacy, property damage, stress, and changes in distance from and visits with family and friends.
The mean age of participants was 63.5 years, 45.0% were men, 70.6% were white, 89.5% had graduated from high school, and 68.3% were married. Mean quality of life scores (standard deviation) were physical functioning 64.6 (30.0), role physical 60.0 (42.8), bodily pain 59.9 (24.3), general health 60.4 (20.5), vitality 53.6 (26.5), social functioning 74.5 (28.1), role emotional 67.8 (41.1), and mental 72.3 (22.0). After adjustment for age, gender, and race, lower coping self-efficacy, more damage to their residence, higher levels of stress after the storm, increased distance from family and friends, and decreased visits with family and friends were associated with lower quality of life. Personal and financial losses were identified as the most common cause of postdisaster stress, reported by 29.6% of participants.
Storm-related factors were associated with lower quality of life in adult patients with hypertension after Hurricane Katrina. Providers managing hypertensive patients in disaster-prone areas may want to consider these factors in identifying patients at risk for lower quality of life following catastrophes.

Hurricane Katrina was one of the most catastrophic natural disasters to hit the United States. It had a major impact on health care in New Orleans, LA and the surrounding region, not only in relation to acute illness but also chronic disease. When Hurricane Katrina struck New Orleans on August 29, 2005, there were 193 participants being followed in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) Trial at Tulane University Health Sciences Center. In the immediate aftermath of the storm, the Tulane University ACCORD Study site, in collaboration with the Study Coordinating Center and the Southeast Clinical Center Network office of the trial at Wake Forest University Health Sciences in North Carolina, took several actions in order to locate the participants, ensure their safety, and maintain the scientific integrity of the trial. We describe the actions taken and the relative success/failure of such actions.

22.  Illicit Drug Markets Among New Orleans Evacuees Before and Soon After Hurricane Katrina 
Journal of drug issues  2007;37(4):981-1006.
This paper analyzes illicit drug markets in New Orleans before and after Hurricane Katrina and access to drug markets following evacuation at many locations and in Houston. Among New Orleans arrestees pre-Katrina, rates of crack and heroin use and market participation was comparable to New York and higher than in other southern cities. Both cities have vigorous outdoor drug markets. Over 100 New Orleans evacuees provide rich accounts describing the illicit markets in New Orleans and elsewhere. The flooding of New Orleans disrupted the city’s flourishing drug markets, both during and immediately after the storm. Drug supplies, though limited, were never completely unavailable. Subjects reported that alcohol or drugs were not being used in the Houston Astrodome, and it was a supportive environment. Outside the Astrodome, they were often approached by or could easily locate middlemen and drug sellers. Evacuees could typically access illegal drug markets wherever they went. This paper analyzes the impact of a major disaster upon users of illegal drugs and the illegal drug markets in New Orleans and among the diaspora of New Orleans evacuees following Hurricane Katrina. This analysis includes data from criminal justice sources that specify what the drug markets were like before this disaster occurred. This analysis also includes some comparison cities where no disaster occurred, but which help inform the similarities and differences in drug markets in other cities. The data presented also include an initial analysis of ethnographic interview data from over 100 New Orleans Evacuees recruited in New Orleans and Houston.

23.  Characterization of Airborne Molds, Endotoxins, and Glucans in Homes in New Orleans after Hurricanes Katrina and Rita▿  
In August and September 2005, Hurricanes Katrina and Rita caused breeches in the New Orleans, LA, levee system, resulting in catastrophic flooding. The city remained flooded for several weeks, leading to extraordinary mold growth in homes. To characterize the potential risks of mold exposures, we measured airborne molds and markers of molds and bacteria in New Orleans area homes. In October 2005, we collected air samples from 5 mildly water-damaged houses, 15 moderately to heavily water-damaged houses, and 11 outdoor locations. The air filters were analyzed for culturable fungi, spores, (1→3,1→6)-β-d-glucans, and endotoxins. Culturable fungi were significantly higher in the moderately/heavily water-damaged houses (geometric mean = 67,000 CFU/m3) than in the mildly water-damaged houses (geometric mean = 3,700 CFU/m3) (P = 0.02). The predominant molds found were Aspergillus niger, Penicillium spp., Trichoderma, and Paecilomyces. The indoor and outdoor geometric means for endotoxins were 22.3 endotoxin units (EU)/m3 and 10.5 EU/m3, respectively, and for (1→3,1→6)-β-d-glucans were 1.7 μg/m3 and 0.9 μg/m3, respectively. In the moderately/heavily water-damaged houses, the geometric means were 31.3 EU/m3 for endotoxins and 1.8 μg/m3 for (1→3,1→6)-β-d-glucans. Molds, endotoxins, and fungal glucans were detected in the environment after Hurricanes Katrina and Rita in New Orleans at concentrations that have been associated with health effects. The species and concentrations were different from those previously reported for non-water-damaged buildings in the southeastern United States.

24.  Association of posttraumatic stress disorder and depression with all-cause and cardiovascular disease mortality and hospitalization among Hurricane Katrina survivors with end-stage renal disease 
American journal of public health  2013;103(4):e130-e137.
To determine the association of psychiatric symptoms in the year after Hurricane Katrina with subsequent hospitalization and mortality in end-stage renal disease (ESRD) patients.
A prospective cohort of ESRD patients (n=391) treated at 9 hemodialysis centers in the New Orleans area in the weeks before Hurricane Katrina were assessed for PTSD and depression symptoms via telephone interview 9–15 months later. Two combined outcomes through August 2009 (maximum 3.5 years follow-up) were analyzed: (1) all-cause and (2) cardiovascular-related hospitalization and mortality.
Twenty-four percent of participants screened positive for PTSD, and 46% for depression; 158 participants died (79 cardiovascular deaths) and 280 participants were hospitalized (167 for cardiovascular related causes). Positive depression screen was associated with 33% higher risk for all-cause (HR = 1.33, 95% CI, 1.06–1.66), and cardiovascular-related hospitalization and mortality (HR = 1.33, 95% CI: 1.01 – 1.76). PTSD was not significantly associated with either outcome.
Depression in the year after Hurricane Katrina was associated with increased risk of hospitalization and mortality in ESRD patients, underscoring the long-term consequences of natural disasters for vulnerable populations.

25.  Serious Emotion Disturbance among Youth Exposed to Hurricane Katrina Two Years Post-Disaster 
To estimate the prevalence of serious emotional disturbance (SED) among children and adolescents exposed to Hurricane Katrina along with the associations of SED with hurricane-related stressors, socio-demographics, and family factors 18–27 months following the hurricane.
A probability sample of pre-hurricane residents of areas affected by Hurricane Katrina was administered a telephone survey. Respondents provided information on up to two of their children (n=797) aged 4–17. The survey assessed hurricane-related stressors and lifetime history of psychopathology in respondents, screened for 12-month SED in respondents’ children using the Strengths and Difficulties Questionnaire (SDQ), and determined whether children’s emotional and behavioral problems were attributable to Hurricane Katrina.
The estimated prevalence of SED was 14.9%, and 9.3% of youth were estimated to have SED that is directly attributable to Hurricane Katrina. Stress exposure was associated strongly with SED, and 20.3% of youth with high stress exposure had hurricane-attributable SED. Death of a loved one had the strongest association with SED among pre-hurricane residents of New Orleans, whereas exposure to physical adversity had the strongest association in the remainder of the sample. Among children with stress exposure, parental psychopathology and poverty were associated with SED.
The prevalence of SED among youth exposed to Hurricane Katrina remains high 18–27 months after the storm, suggesting a substantial need for mental health treatment resources in the hurricane-affected areas. Youth who were exposed to hurricane-related stressors, have a family history of psychopathology, and have lower family incomes are at greatest risk for long-term psychiatric impairment.
