Association between severity of symptoms and minimum mental health treatment duration in humanitarian contexts: a retrospective observational study. EClinicalMedicine 2024; 67:102362. [PMID: 38125965 PMCID: PMC10730340 DOI: 10.1016/j.eclinm.2023.102362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 11/21/2023] [Accepted: 11/22/2023] [Indexed: 12/23/2023] Open
Abstract
Background Understanding and optimising mental health and psychosocial support (MHPSS) interventions in humanitarian crises is crucial, particularly for the most prevalent mental health conditions in conflict settings: anxiety, depression, and post-traumatic stress disorder. However, research on what is the most appropriate length of psychological intervention is lacking in this setting. We aimed to establish which factors are most closely related to improvement and to determine the required number of consultations needed to achieve this improvement. Methods We retrospectively analysed records from 9028 patients allocated to treatment for anxiety, depression, and post-traumatic symptoms from the MHPSS programme in Borno State, Nigeria, from January 2018 to December 2019. Patient characteristics, severity (Clinical Global Impression of Severity Scale, CGI-S scale), and clinical improvement were assessed by an attending counsellor (CGI-I scale) and by the patient (Mental Health Global State, MHGS scale). Improvement was defined as scores 1, 2, and 3 in the Clinical Global Impression of Improvement (CGI-I) scale, and as a decrease of at least 4 points in the MHGS scale. We investigated the associations between the category of symptoms, the severity of illness, and improvement of symptoms using multivariable logistic regression. We used Kaplan-Meier (KM) curves to assess the number of consultations (i.e., time of treatment) needed to achieve improvement of symptoms, by symptom category and symptom severity. Findings The patients included were referred to treatment for anxiety (n = 3462), depression (n = 3970), or post-traumatic symptoms (n = 1596). Median age was 31 years (range 16-103), and 84.3% were female. Patients categorised as severe were less likely to present improvement according to the CGI-I scale (OR 0.11, 95% CI 0.05-0.25), while none of the other categories of symptoms showed significant results. Overall, three or more consultations were associated with improvement in both scales (OR 3.55, 95% CI 1.47-8.57 for CGI-I; and OR 3.04, 95% CI 2.36-3.90 for MHGS). KM curves for the category of symptoms showed that around 90% of patients with anxiety, depression, or post-traumatic symptoms, as well as those with mild or moderate severity, presented improvement after three consultations, compared with six consultations for those with severe symptoms. Interpretation Classification by severity among patients with anxiety, depression, or post-traumatic symptoms could predict the probability of improvement, whereas classification by symptoms could not. Our study highlights the importance of classifying patient severity in MHPSS programmes to plan and implement the appropriate duration of care. A major limitation was the number of patients lost to follow up after the first consultation and excluded from the logistic regression and KM analysis. Funding The study was funded and staffed entirely by Médicos Sin Fronteras (Médecins Sans Frontières), Spain.

Abstract
OBJECTIVE Description of tuberculosis (TB)-focused point-of-care ultrasound (POCUS) findings for children with presumptive TB. DESIGN Cross-sectional study (July 2019 to April 2020). SETTING Simão Mendes hospital in Bissau, a setting with high TB, HIV, and malnutrition burdens. PARTICIPANTS Patients aged between 6 months and 15 years with presumptive TB. INTERVENTIONS Participants underwent clinical, laboratory and unblinded clinician-performed POCUS assessments, to assess subpleural nodules (SUNs), lung consolidation, pleural and pericardial effusion, abdominal lymphadenopathy, focal splenic and hepatic lesions and ascites. Presence of any sign prompted a POCUS positive result. Ultrasound images and clips were evaluated by expert reviewers and, in case of discordance, by a second reviewer. Children were categorised as confirmed TB (microbiological diagnosis), unconfirmed TB (clinical diagnosis) or unlikely TB. Ultrasound findings were analysed per TB category and risk factor: HIV co-infection, malnutrition and age. RESULTS A total of 139 children were enrolled, with 62 (45%) women and 55 (40%) aged <5 years; 83 (60%) and 59 (42%) were severely malnourished (SAM) and HIV-infected, respectively. TB confirmation occurred in 27 (19%); 62 (45%) had unconfirmed TB and 50 (36%) had unlikely TB. Children with TB were more likely to have POCUS-positive results (93%) compared with children with unlikely TB (34%). Common POCUS signs in patients with TB were: lung consolidation (57%), SUNs (55%) and pleural effusion (30%), and focal splenic lesions (28%). In children with confirmed TB, POCUS sensitivity was 85% (95% CI) (67.5% to 94.1%). In those with unlikely TB, specificity was 66% (95% CI 52.2% to 77.6%). Unlike HIV infection and age, SAM was associated with a higher POCUS-positivity. Cohen's kappa coefficient for concordance between field and expert reviewers ranged from 0.6 to 0.9. CONCLUSIONS We found a high prevalence of POCUS signs in children with TB compared with children with unlikely TB. POCUS-positivity was dependent on nutritional status but not on HIV status or age. TB-focused POCUS could potentially play a supportive role in the diagnosis of TB in children. TRIAL REGISTRATION NUMBER NCT05364593.

Severity, symptomatology, and treatment duration for mental health disorders: a retrospective analysis from a conflict-affected region of northern Nigeria. Confl Health 2022; 16:41. [PMID: 35840991 PMCID: PMC9284755 DOI: 10.1186/s13031-022-00473-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 06/05/2022] [Indexed: 11/24/2022] Open
Abstract
Background Mental Health and psychosocial support (MHPSS) programs are essential during humanitarian crises and in conflict settings, like Nigeria’s Borno State. However, research on how types of traumatic stress and symptom severity affect clinical improvement is lacking in these contexts, as is consensus over how long these patients must engage in mental health care to see results.
Methods Records from 11,709 patients from the MHPSS program in Pulka and Gwoza local government areas in Borno State, Nigeria from 2018 and 2019 were retrospectively analyzed. Patient information, symptoms, stress type, severity (CGI-S scale), and clinical improvement (CGI-I and MHGS scales) were assessed by the patient and counselor. Associations between variables were investigated using logistic regression models. Results Clinical improvement increased with consultation frequency (OR: 2.5, p < 0.001 for CGI-I; OR: 2, p < 0.001 for MHGS), with patients who received three to six counseling sessions were most likely to improve, according to severity. Survivors of sexual violence, torture, and other conflict/violence-related stressors were nearly 20 times as likely to have posttraumatic stress disorder (PTSD) (OR: 19.7, p < 0.001), and depression (OR: 19.3, p < 0.001) symptomatology. Children exposed to conflict-related violence were also almost 40 times as likely to have PTSD (OR: 38.2, p = 0.002). Most patients presented an improvement in outcome at discharge, per both counselors (92%, CGI-I) and self-rating scores (73%, MHGS). Conclusion We demonstrate a threshold at which patients were most likely to improve (3 sessions for mild or moderate patients; 6 sessions for severe). In addition, we identify the specific types of stress and symptom severity that affected the number of sessions needed to achieve successful outcomes, and highlight that some stress types (especially torture or having a relative killed) were specifically linked to PTSD and depression. Therefore, we emphasize the importance of classifying patient stress type and severity to identify the appropriate duration of care needed.

Seroprevalence and risk factors of exposure to COVID-19 in homeless people in Paris, France: a cross-sectional study. Lancet Public Health 2021; 6:e202-e209. [PMID: 33556328 PMCID: PMC7993986 DOI: 10.1016/s2468-2667(21)00001-3] [Citation(s) in RCA: 68] [Impact Index Per Article: 22.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 12/14/2020] [Accepted: 12/21/2020] [Indexed: 01/20/2023]
Abstract
BACKGROUND During the COVID-19 lockdown period from March 17 to May 11, 2020, French authorities in Paris and its suburbs relocated people experiencing recurrent homelessness to emergency shelters, hotels, and large venues. A serological survey was done at some of these locations to assess the COVID-19 exposure prevalence in this group. METHODS We did a cross-sectional seroprevalence study at food distribution sites, emergency shelters, and workers' residences that were provided medical services by Médecins Sans Frontières in Paris and Seine-Saint-Denis in the Ile-de-France region. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody seropositivity was detected by Luciferase-Linked Immunosorbent Assay and Pseudo Neutralization Test. Sociodemographic and exposure related information was collected via a verbal questionnaire to analyse risk factors and associations with various COVID-19 symptoms. FINDINGS Between June 23 and July 2, 2020, 426 (52%) of 818 individuals recruited tested positive in 14 sites. Seroprevalence varied significantly by type of recruitment site (χ2 p<0·0001), being highest among those living in workers' residences (88·7%, 95% CI 81·8-93·2), followed by emergency shelters (50·5%, 46·3-54·7), and food distribution sites (27·8%, 20·8-35·7). More than two thirds of COVID-19 seropositive individuals (68%, 95% CI 64·2-72·2; 291 of 426) did not report any symptoms during the recall period. COVID-19 seropositivity was strongly associated with overcrowding (medium density: adjusted odds ratio [aOR] 2·7, 95% CI 1·5-5·1, p=0·0020; high density: aOR 3·4, 1·7-6·9, p<0·0001). INTERPRETATION These results show high exposure to SARS-CoV-2 with important variations between those at different study sites. Living in crowded conditions was the strongest factor associated with exposure level. This study underscores the importance of providing safe, uncrowded accommodation, alongside adequate testing and public health information.

Development of a patient rated scale for mental health global state for use during humanitarian interventions. Int J Methods Psychiatr Res 2021; 30:e1850. [PMID: 32945587 PMCID: PMC7992285 DOI: 10.1002/mpr.1850] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 05/29/2020] [Accepted: 07/28/2020] [Indexed: 11/11/2022] Open
Abstract
OBJECTIVE We present the results of a cross-cultural validation of the Mental Health Global State (MHGS) scale for adults and adolescents (<14 years old). METHODS We performed two independent studies using mixed methods among 103 patients in Hebron, Occupied Palestinian Territories and 106 in Cauca, Colombia. The MHGS was analyzed psychometrically, sensitivity and specificity, ability to detect clinically meaningful change, compared to the Clinical Global Impression-Severity scale (CGI-S). Principal component analysis was used to reduce the number of questions after data collection. RESULTS The scale demonstrated good internal consistency, with a Cronbach alpha score of 0.80 in both settings. Test retest reliability was high, ICC 0.70 (95% CI [0.41-0.85]) in Hebron and 0.87 (95% CI [0.76-0.93]) in Cauca; inter-rater reliability was 0.70 (95% CI [0.42-0.85]) in Hebron and 0.76 (95% CI [0.57-0.88]) in Cauca. Psychometric properties were also good, and the tool demonstrated a sensitivity of 85% in Hebron and 100% in Cauca, with corresponding specificity of 80% and 79%, when compared to CGI-S. CONCLUSIONS The MHGS showed promising results to assess global mental health thereby providing an additional easy to use tool in humanitarian interventions. Additional work should focus on validation in at least one more context, to adhere to best practices in transcultural validation.

Neighborhood-targeted and case-triggered use of a single dose of oral cholera vaccine in an urban setting: Feasibility and vaccine coverage. PLoS Negl Trop Dis 2017; 11:e0005652. [PMID: 28594891 PMCID: PMC5478158 DOI: 10.1371/journal.pntd.0005652] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Revised: 06/20/2017] [Accepted: 05/19/2017] [Indexed: 02/02/2023] Open
Abstract
INTRODUCTION In June 2015, a cholera outbreak was declared in Juba, South Sudan. In addition to standard outbreak control measures, oral cholera vaccine (OCV) was proposed. As sufficient doses to cover the at-risk population were unavailable, a campaign using half the standard dosing regimen (one-dose) targeted high-risk neighborhoods and groups including neighbors of suspected cases. Here we report the operational details of this first public health use of a single-dose regimen of OCV and illustrate the feasibility of conducting highly targeted vaccination campaigns in an urban area. METHODOLOGY/PRINCIPAL FINDINGS Neighborhoods of the city were prioritized for vaccination based on cumulative attack rates, active transmission and local knowledge of known cholera risk factors. OCV was offered to all persons older than 12 months at 20 fixed sites and to select groups, including neighbors of cholera cases after the main campaign ('case-triggered' interventions), through mobile teams. Vaccination coverage was estimated by multi-stage surveys using spatial sampling techniques. 162,377 individuals received a single-dose of OCV in the targeted neighborhoods. In these neighborhoods vaccine coverage was 68.8% (95% Confidence Interval (CI), 64.0-73.7) and was highest among children ages 5-14 years (90.0%, 95% CI 85.7-94.3), with adult men being less likely to be vaccinated than adult women (Relative Risk 0.81, 95% CI: 0.68-0.96). In the case-triggered interventions, each lasting 1-2 days, coverage varied (range: 30-87%) with an average of 51.0% (95% CI 41.7-60.3). CONCLUSIONS/SIGNIFICANCE Vaccine supply constraints and the complex realities where cholera outbreaks occur may warrant the use of flexible alternative vaccination strategies, including highly-targeted vaccination campaigns and single-dose regimens. We showed that such campaigns are feasible. Additional work is needed to understand how and when to use different strategies to best protect populations against epidemic cholera.

Abstract
Background The Central African Republic has known long periods of instability. In 2014, following the fall of an interim government installed by the Séléka coalition, a series of violent reprisals occurred. These events were largely directed at the country’s Muslim minority and led to a massive displacement of the population. In 2014, we sought to document the retrospective mortality among refugees arriving from the CAR into Chad by conducting a series of surveys. Methods The Sido camp was surveyed exhaustively in March-April 2014 and a systematic sampling strategy was used in the Goré camp in October 2014. The survey recall period began November 1, 2013, just before the major anti-Balaka offensive. Heads of households were asked to describe their household composition at the beginning of and throughout the recall period. For household members reported as dying, further information about the date and circumstances of death was obtained. Results In Sido, 3449 households containing 25 353 individuals were interviewed. A total of 2599 deaths were reported, corresponding to a crude mortality rate of 6.0/10000 persons/day, and 8% of the population present at the beginning of the recall period died. Most (82.4%) deaths occurred among males, most deaths occurred in December 2013 and January 2014, and 92% were due to violence in the CAR. In Goré, 1383 households containing 8614 individuals were interviewed. A total of 1203 deaths were reported, corresponding to a crude mortality rate of 3.7/10000 persons/day [95%CI 3.5–3.9], and 12% of the population present at the beginning of the recall period died. Most (77.1%) deaths occurred among males. As in Sido, most deaths occurred in December 2013 and January 2014, and 86% of all deaths were due to violence in the CAR. Conclusions The results of these two surveys describe a part of the toll of the violent events of December 2013 and January 2014 in the Central African Republic.

Abstract
BACKGROUND Time and resource efficient mental disorder screening mechanisms are not available to identify the growing number of refugees and other forcibly displaced persons in priority need for mental health care. The aim of this study was to identify efficient screening instruments and mechanisms for the detection of moderate and severe mental disorders in a refugee setting. METHODS Lay interviewers applied a screening algorithm to detect individuals with severe distress or mental disorders in randomly selected households in a Palestinian refugee camp in Beirut, Lebanon. The method included household informant and individual level interviews using a Vignettes of Local Terms and Concepts for mental disorders (VOLTAC), individual and household informant portions of the field-test version of the WHO-UNHCR Assessment Schedule of Serious Symptoms in Humanitarian Settings (WASSS) and the WHO Self Reporting Questionnaire (SRQ-20). A subset of participants were then reappraised utilizing the Mini International Neuropsychiatric Interview (MINI), WHO Disability Assessment Schedule II, and the Global Assessment of Functioning. The study constitutes a secondary analysis of interview data from 283 randomly selected households (n = 748 adult residents) who participated in a mental health disorders prevalence study in 2010. RESULTS The 5-item household informant portion of WASSS was the most efficient instrument among those tested. It detected adults with severe mental disorders with 95% sensitivity and 71% specificity (Area Under Curve (AUC) = 0.85) and adults with moderate or severe mental disorder with 85.1% sensitivity and 74.8% specificity (AUC = 0.82). The complete screening algorithm demonstrated 100% sensitivity and 58% specificity. CONCLUSIONS Our results suggest that a two phase, screen-confirm approach is likely a useful strategy to detect incapacitating mental disorders in humanitarian contexts where mental health specialists are scarce, and that in the context of a multi-step screen confirm mechanism, the household informant portion of field-test version of the WASSS may be an efficient screening tool to identify adults in greatest need for mental health care in humanitarian settings.

Abstract
Background A large poliomyelitis outbreak occurred in 2010 in the Republic of Congo. This paper describes the demographic and clinical characteristics of poliomyelitis cases and their outcomes following physiotherapy. Findings Demographic and clinical data were collected on 126 individuals between November 23, 2010 and March 23, 2011. The male/female ratio was 2.5 and the median age was 19 years (IQR: 13.5-23). The most severe forms of the disease were more common in older patients, 81 of the 126 patients (64.3%) had multiple evaluations of muscle strength. Among patients with multiple evaluations, 38.1% had improved strength at final evaluation, 48.3% were stable and 13.6% had decreased strength. Conclusions Most acute poliomyelitis patients receiving physiotherapy had improved or stable muscle strength at their final evaluation. These descriptive results highlight the need for further research into the potential benefits of physiotherapy in polio affected patients.

Abstract
BACKGROUND Studies have shown high levels of distress and mental disorder among people living in refugee camps, yet none has confirmed diagnosis through clinical reappraisal. AIMS To estimate the prevalence of mental disorders, related disability and treatment gap in adult refugees living in the Burj el-Barajneh camp. METHOD Randomly selected participants were screened by household representative (n = 748) and individual (n = 315) interviews; clinical reappraisal was performed on a subset (n = 194) of 326 selected participants. Weighted prevalence estimates and 95% confidence intervals were calculated. RESULTS The prevalence of current mental disorders was 19.4% (95% CI 12.6-26.2); depression was the most common diagnosis (8.3%, 95% CI 4.4-12.2) and multiple diagnoses were common (42%) among the 88 persons with mental disorder. Lifetime prevalence of psychosis was 3.3% (95% CI 1.0-5.5). Mental disorders were associated with moderate to severe dysfunction (odds ratio = 8.8, 95% CI 4.5-17.4). The treatment gap was 96% (95% CI 92-100). CONCLUSIONS A range of mental disorders and associated disability are common in this long-term refugee setting. Combined with an important treatment gap, findings support the current consensus-based policy to prioritise availability of mental health treatment in refugee camps, especially for the most severe and disabling conditions.

Brief mental health interventions in conflict and emergency settings: an overview of four Médecins Sans Frontières - France programs. Confl Health 2013; 7:23. [PMID: 24182311 PMCID: PMC3829376 DOI: 10.1186/1752-1505-7-23] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2013] [Accepted: 10/24/2013] [Indexed: 11/22/2022] Open
Abstract
INTRODUCTION Mental health problems, particularly anxiety and mood disorders, are prevalent in the setting of humanitarian emergencies, both natural and man-made disasters. Evidence regarding best strategies for therapeutic interventions is sparse. Médecins Sans Frontières has been providing mental health services during emergencies for over two decades, and here we compare data from four programs. PROGRAM OVERVIEW In China, 564 patients were followed for an average of 7 sessions after a major earthquake. The most common diagnoses were PTSD and other anxiety disorders. Between program entry and exit, the median global assessment of functioning increased from 65 to 80. At program entry, 58% were considered moderately, markedly or severely ill; a proportion which fell to 14% at program exit. In Colombia in the setting of chronic violence, 2411 patients were followed for a median of two sessions. Anxiety disorders and major depression were the most common diagnoses, and 76% of patients were moderately or severely ill at program entry. 91% had symptomatic improvement at program exit. In Gaza, 1357 patients were followed for a median of 9 sessions; a majority was under age 15. PTSD and other anxiety disorders were the most common diagnoses, and 91% were moderately or severely ill at entry. 89% had improved symptoms at program exit. In the West Bank, the 1478 patients had similar characteristics to those enrolled in Gaza. 88% were moderately or severely ill at entry; 88% had improved at exit. DISCUSSION AND EVALUATION It was feasible to implement brief yet effective mental health interventions in a wide variety of humanitarian contexts - post-natural disaster, during acute violent conflict and during chronic violent conflict. The most common diagnoses were PTSD, other anxiety disorders and mood disorders. The use of local specially-trained counselors who were focused on coping skills and improving functionality over a brief time period, likely contributed to the symptomatic improvement seen in a large majority of patients across the four sites. CONCLUSIONS Mental health is an essential part of a health care response to humanitarian emergencies. In a variety of settings, we show the positive results of brief interventions. Further research is needed to improve and evaluate mental health interventions in crises.

Diagnosis and classification of disorders specifically associated with stress: proposals for ICD-11. World Psychiatry 2013; 12:198-206.

Abstract
The diagnostic concepts of post-traumatic stress disorder (PTSD) and other disorders specifically associated with stress have been intensively discussed among neuro- and social scientists, clinicians, epidemiologists, public health planners and humanitarian aid workers around the world. PTSD and adjustment disorder are among the most widely used diagnoses in mental health care worldwide. This paper describes proposals that aim to maximize clinical utility for the classification and grouping of disorders specifically associated with stress in the forthcoming 11th revision of the International Classification of Diseases (ICD-11). Proposals include a narrower concept for PTSD that does not allow the diagnosis to be made based entirely on non-specific symptoms; a new complex PTSD category that comprises three clusters of intra- and interpersonal symptoms in addition to core PTSD symptoms; a new diagnosis of prolonged grief disorder, used to describe patients that undergo an intensely painful, disabling, and abnormally persistent response to bereavement; a major revision of "adjustment disorder" involving increased specification of symptoms; and a conceptualization of "acute stress reaction" as a normal phenomenon that still may require clinical intervention. These proposals were developed with specific considerations given to clinical utility and global applicability in both low- and high-income countries.

Abstract
UNLABELLED BACKGROUND There is growing recognition of the psychological impact of adversity associated with armed conflict on exposed civilian populations. Yet there is a paucity of evidence on the value of mental health programs in these contexts, and of the chronology of psychological sequelae, especially in prolonged conflicts with repeated cycles of extreme violence. Here, we describe changes in the psychological profile of new patients in a mental health program after the military offensive Cast Lead, in the context of the prolonged armed conflict involving the Gaza Strip. METHODS This study analyses routinely collected program data from a Médecins Sans Frontières mental health program in the Gaza Strip spanning 2007-2011. Data consist of socio-demographic as well as clinical baseline and follow-up data on new patients entering the program. Comparisons were made through Chi square and Fisher's exact tests, univariate and multivariate logistic and linear regression. RESULTS PTSD, depression and other anxiety disorders were the most frequent psychopathologies, with 21% having multiple diagnoses. With a median of nine sessions, clinical improvement was recorded for 83% (1122/1357), and more common for those with separation anxiety, acute and posttraumatic disorders as principal diagnosis (855/1005), compared to depression (141/183, p<0.01). Noted changes proximal to Operation Cast Lead were: a doubling in patient case load with a broader socio-economic background, shorter interval from an identified traumatic event to seeking care, and a rise in diagnoses of acute and posttraumatic stress disorders. Sustained changes included: high case load, more distal triggering events, and increase in diagnoses of other anxiety disorders (especially for children 15 years and younger) and depression (especially for patients 16 years and older). CONCLUSION Evolving changes in patient volume, diagnoses and recall period to triggering events suggest a lengthy and durable effect of an intensified exposure to violence in a context of prolonged conflict. Our findings suggest that mental health related humanitarian relief in protracted conflicts might need to prepare for an increase in patients with changing profiles over an extended period following an acute flare-up in violence.

Evaluation and use of surveillance system data toward the identification of high-risk areas for potential cholera vaccination: a case study from Niger. BMC Res Notes 2012; 5:231. [PMID: 22583566 PMCID: PMC3413562 DOI: 10.1186/1756-0500-5-231] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2011] [Accepted: 05/14/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In 2008, Africa accounted for 94% of the cholera cases reported worldwide. Although the World Health Organization currently recommends the oral cholera vaccine in endemic areas for high-risk populations, its use in Sub-Saharan Africa has been limited. Here, we provide the principal results of an evaluation of the cholera surveillance system in the region of Maradi in Niger and an analysis of its data towards identifying high-risk areas for cholera. RESULTS We evaluated the cholera surveillance data using a standard CDC protocol, through interviews with heads of the system, and a review of cholera data collected between 2006-2009. The surveillance system was found to be sufficiently reliable to be able to utilize the data for the detection of high risk areas for cholera vaccination. Temporal, geographic and socio-demographic analyses of cholera cases indicated that between 2006 and 2009, 433 cholera cases were reported in the Maradi region of Niger. Two deprived neighborhoods of the region's capital city, Bagalam and Yandaka, represented 1% of the regional population and 21% of the cholera cases, reaching a yearly incidence rate of 3 per 1000 in 2006 and 2008, respectively. CONCLUSIONS The results of this evaluation suggest that the reporting sensitivity of the surveillance system is sufficient, to appropriately classify the region as cholera endemic. Additionally, two overcrowded neighborhoods in the regional capital met WHO criteria for consideration for cholera vaccination.

Abstract
On November 4, 2010, the Republic of the Congo declared a poliomyelitis outbreak. A cross-sectional survey in Pointe-Noire showed poor sanitary conditions and low vaccination coverage (55.5%), particularly among young adults. Supplementary vaccination should focus on older age groups in countries with evidence of immunity gaps.

Abstract
BACKGROUND Infection with Helicobacter pylori is an established risk factor for gastric cancer. Results from two studies suggest that it may also be a risk factor for pancreatic cancer. METHODS We conducted a nested case control study among 128,992 adult subscribers to the Kaiser Permanente Medical Care Program who had been enrolled in a multiphasic health checkup from 1964 to 1969. Serum collected during the checkup was maintained frozen, and subjects were followed for cancer. Cases consisted of 104 randomly selected subjects among 507 who developed pancreatic cancer in the cohort. Controls consisted of 262 pancreatic cancer-free subjects from a pool of 730 controls previously tested for studies conducted on this cohort. Controls were individually matched to cases on age, gender, race, site, and date of multiphasic health checkup. Control sera were compared with cases for antibodies to H. pylori and the CagA protein. The effects of smoking, alcohol consumption, obesity, and years of education were also investigated. RESULTS Neither H. pylori [odds ratio (OR), 0.85; 95% confidence interval (95% CI), 0.49-1.48] nor its CagA protein (OR, 0.96; 95% CI, 0.48-1.92) was associated with subsequent development of pancreatic cancer. Smoking (OR, 2.09; 95% CI, 1.17-3.74) and greater number of years of education (OR, 2.13; 95% CI, 1.23-3.69) were risk factors for pancreatic cancer, whereas alcohol consumption and obesity were not. CONCLUSION Our results suggest that H. pylori infection is not associated with development of pancreatic cancer.

Helicobacter pylori infection and the risk of development of esophageal adenocarcinoma. J Infect Dis 2005; 191:761-7.

Abstract
BACKGROUND An increase in the incidence of esophageal adenocarcinoma has coincided with a decrease in the prevalence of Helicobacter pylori infection. Whether these 2 phenomena are associated is unknown. METHODS We conducted a nested case-control study of 128,992 members of an integrated health care system who had participated in a multiphasic health checkup (MHC) during 1964-1969. During follow-up, 52 patients developed esophageal adenocarcinoma. Three randomly chosen control subjects from the MHC cohort were matched to each case subject, on the basis of age at the MHC, sex, race, and the date and site of the MHC. Data on cigarette smoking, alcohol consumption, body mass index (BMI), and education level were obtained at the MHC. Serum samples collected at the MHC were tested for IgG antibodies to H. pylori and to the H. pylori CagA protein. RESULTS Subjects with H. pylori infections were less likely than uninfected subjects to develop esophageal adenocarcinoma (odds ratio [OR], 0.37 [95% confidence interval (CI), 0.16-0.88]). This significant association was restricted to case subjects and control subjects <50 years old at the MHC (OR, 0.20 [95% CI, 0.06-0.68]). In patients with H. pylori infections, the OR for those who tested positive for IgG antibodies to the CagA protein was similar to that for those who tested negative for it. BMI >/=25 and cigarette smoking were strong independent risk factors for development of esophageal adenocarcinoma. CONCLUSION The absence of H. pylori infection, independent of cigarette smoking and BMI, is associated with a markedly increased risk of development of esophageal adenocarcinoma.

Abstract
BACKGROUND The objective of this study was to investigate risk factors associated with persistent or recurrent upper extremity and neck pain among engineering graduate students. METHODS A random sample of 206 Electrical Engineering and Computer Science (EECS) graduate students at a large public university completed an online questionnaire. RESULTS Approximately 60% of respondents reported upper extremity or neck pain attributed to computer use and reported a mean pain severity score of 4.5 (+/-2.2; scale 0-10). In a final logistic regression model, female gender, years of computer use, and hours of computer use per week were significantly associated with pain. CONCLUSIONS The high prevalence of upper extremity pain reported by graduate students suggests a public health need to identify interventions that will reduce symptom severity and prevent impairment.

Abstract
BACKGROUND In 1998, the FDA recommended look-back for HCV. The recommendation was initially limited, however, to donors who reacted on a multiantigen HCV screening test and to components collected since January 1, 1988. A lookback program was extended to include donors who reacted on the first-generation (single-antigen) HCV screening test and who were positive on a supplemental assay (RIBA-1 or -2) and all components for which transfusion records could be found (back to 1978). STUDY DESIGN AND METHODS The yield of the incremental lookback programs was compared to that originally recommended by the FDA by comparing the number of newly identified HCV-positive recipients in each program. The results of lookbacks were reviewed on 385 blood components for which 314 transfusion recipients were identified. RESULTS Of the 135 recipients in the FDA program, 70 percent were dead, 28 percent were living and notified, and 2 percent could not be located. In the incremental programs, there were 179 recipients, of whom 80.4 percent were dead, 16.2 percent were living and notified, and 3.4 percent could not be located. Most adult recipients were dead (81%), but the majority of pediatric recipients were alive (57%); 76 percent of tested recipients were HCV seropositive, with no significant difference between programs. One-half of test-positive recipients in each program were newly identified through the lookback program. Seven of the 20 newly identified HCV-positive recipients were found through the incremental programs. The yield, defined as newly detected HCV cases per total number of recipients, was 9.6 percent for the FDA and 3.9 percent for the incremental programs. This difference was significant (p = 0.04). CONCLUSION The yield of both programs was limited by the high percentage of recipients who had died. Pediatric recipients were more likely to be living at the time of notification. The incremental program was less efficacious than the FDA program in identifying newly HCV-positive recipients, but one-third of the newly detected HCV cases were identified through the incremental program.
