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 p p p 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.

Background‘Digital Mental Health services,’ or mental health care delivered via internet, computers, mobile phones, tablets, or text messaging services, are an increasingly important way to expand care to underserved groups in low-resource settings. In order to continue providing psychiatric, psychotherapeutic and counselling care during COVID-19-related movement restrictions, Médecins Sans Frontières (MSF), a humanitarian medical organization, abruptly transitioned part of its mental health (MH) activities to digitally supported remote services in 2020 across humanitarian and resource-constrained settings. MethodsFrom June-July of 2020, investigators used a mixed method, sequential explanatory study design to assess MSF staff perceptions of digital MH services provided during the COVID-19 crisis. Preliminary quantitative results influenced qualitative question guide design. Eighty-one quantitative online questionnaires were collected and a subset of 13 qualitative follow-up in-depth interviews (IDI) occurred.ResultsRespondents in 44 countries (6 world regions), mostly from Sub-Saharan Africa (39.5%), the Middle East (18.5%) and Asia (13.6%) participated. Most digital MH interventions depended on audio-only platforms (80%). 30% of respondents reported that more than half of their patients were unreachable using digital interventions, usually because of poor network coverage (73.8%), a lack of communication devices (72.1%), or a lack of a private space at home (67.2%). Nearly half (47.5%) of respondents felt their staff had a decreased ability to provide comprehensive MH care using digital platforms. Most respondents thought MH staff had a negative (46%) or mixed (42%) impression of remote care. Nevertheless, almost all respondents (96.7%) thought digital MH services had some degree of utility, most commonly citing improved access to care (37.7%) and greater time efficiency (32.8%) as reasons for its continued use.ConclusionDigital MH activities were seen as an acceptable alternative to in-person therapeutic interventions in humanitarian settings during the COVID-19 pandemic. However, they were not considered suitable for all patients in the humanitarian contexts studied, especially survivors of sexual or interpersonal violence, pediatric and geriatric cases, and patients with severe MH conditions. Audio-only technologies that lacked non-verbal cues were particularly challenging and made risk assessment and emergency care more difficult. Prior to considering digital MH services, communications infrastructure should be assessed, and comprehensive, context-specific protocols should be developed.

Summary: 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

BackgroundWe present results from an intervention case study, the Soins Preventifs de l’Enfant (SPE) project, in Konséguéla health area, Mali. The intervention involved a network of community health workers providing a comprehensive preventive/therapeutic package, ultimately aiming at reducing under 24-month mortality. Associated costs were documented to assess the feasibility of replication and scale-up.MethodsSPE program monitoring data were obtained from booklets specific to the program between 2010 and 2014. Data included sex, age, vaccination status, anthropometric measurements, Ready-To-Use-Supplementary Food distribution, morbidities reported by the mother between visits, hospitalizations over 18 months of follow-up. Cross-sectional surveys in the district of Koutiala, of which Konséguéla is one health area, were conducted yearly between 2010 and 2014 for comparison, using difference-in-difference approach. Ethical approval was granted from the Malian Ethical Committee.ResultsGlobal and Severe Acute Malnutrition prevalences decreased over time in Konséguéla as well as in the rest of the district, but the difference between areas was not significant. Children reaching 24 months were 20% less stunted in Konséguéla than children the same age outside (pConclusionThe results of this case study suggest a sustained impact of a community based, comprehensive health package on major child health indicators. Most notably, while improvements in acute malnutrition were found in the district as a whole, those in the intervention area were more pronounced. Trends for other indicators suggest additional benefits.

Objective We present the results of a cross‐cultural validation of the Mental Health Global State (MHGS) scale for adults and adolescents (

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., Author summary Oral cholera vaccine (OCV) is becoming part of the standard cholera-control toolkit, although experience in deploying OCV is limited. Adapting vaccination strategies to the global availability of vaccines and the local context (i.e., population movement, security constraints, etc.) is key to maximize the impact of OCV as a cholera-control tool. Here we describe the operational details of the first field use of a single-dose of OCV, which was deployed in a targeted manner, both at high-risk neighborhoods and then to neighbors of suspected cases after the main OCV campaign when sporadic cholera case reports continued. We show that it is feasible to conduct micro- and macro-targeted vaccination campaigns in urban areas like Juba with moderate to high coverage and without social unrest due to vaccinating some groups and not others. Flexible and context-adapted OCV dosing regimens and strategies should be considered in future deployments of the vaccine.

BackgroundStudies have shown high levels of distress and mental disorder among people living in refugee camps, yet none has confirmed diagnosis through clinical reappraisal.AimsTo estimate the prevalence of mental disorders, related disability and treatment gap in adult refugees living in the Burj el-Barajneh camp.MethodRandomly 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.ResultsThe 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).ConclusionsA 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.

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 o f 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.

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.

Summary Background Oral cholera vaccines represent a new effective tool to fight cholera and are licensed as two-dose regimens with 2–4 weeks between doses. Evidence from previous studies suggests that a single dose of oral cholera vaccine might provide substantial direct protection against cholera. During a cholera outbreak in May, 2015, in Juba, South Sudan, the Ministry of Health, Medecins Sans Frontieres, and partners engaged in the first field deployment of a single dose of oral cholera vaccine to enhance the outbreak response. We did a vaccine effectiveness study in conjunction with this large public health intervention. Methods We did a case-cohort study, combining information on the vaccination status and disease outcomes from a random cohort recruited from throughout the city of Juba with that from all the cases detected. Eligible cases were those aged 1 year or older on the first day of the vaccination campaign who sought care for diarrhoea at all three cholera treatment centres and seven rehydration posts throughout Juba. Confirmed cases were suspected cases who tested positive to PCR for Vibrio cholerae O1. We estimated the short-term protection (direct and indirect) conferred by one dose of cholera vaccine (Shanchol, Shantha Biotechnics, Hyderabad, India). Findings Between Aug 9, 2015, and Sept 29, 2015, we enrolled 87 individuals with suspected cholera, and an 898-person cohort from throughout Juba. Of the 87 individuals with suspected cholera, 34 were classified as cholera positive, 52 as cholera negative, and one had indeterminate results. Of the 858 cohort members who completed a follow-up visit, none developed clinical cholera during follow-up. The unadjusted single-dose vaccine effectiveness was 80·2% (95% CI 61·5–100·0) and after adjusting for potential confounders was 87·3% (70·2–100·0). Interpretation One dose of Shanchol was effective in preventing medically attended cholera in this study. These results support the use of a single-dose strategy in outbreaks in similar epidemiological settings. Funding Medecins Sans Frontieres.

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

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.

Background: In 2009, a large meningitis A epidemic affected a broad region of northern Nigeria and southern Niger, resulting in more than 75 000 cases and 4000 deaths. In collaboration with state and federal agencies, Medecins Sans Frontieres (MSF) intervened with a large-scale vaccination campaign using polysaccharide vaccine. Here the authors analyze the impact (cases averted) of the vaccination response as a function of the timing and coverage achieved. Methods: Phenomenological epidemic models were fitted to replicate meningitis surveillance data from the Nigerian Ministry of Health/WHO surveillance system and from reinforced surveillance conducted by MSF in both vaccinated and unvaccinated areas using a dynamic, state-space framework to account for under-report- ing of cases. Results: The overall impact of the vaccination campaigns (reduction in meningitis cases) in Katsina State, northern Nigeria, ranged from 4% to 12%. At the local level, vaccination reduced cases by as much as 50% when campaigns were conducted early in the epidemic. Conclusions: Reactive vaccination with polysaccharide vaccine during meningitis outbreaks can significantly reduce the case burden when conducted early and comprehensively. Introduction of the conjugate MenAfriVac vaccine has reduced rates of disease caused by serogroup A Neisseria meningitidis in the region. Despite this, reactive campaigns with polysaccharide vaccine remain a necessary and important tool for meningitis outbreak response.

We compared Mycobacterium tuberculosis sputum culture recovery and contamination rates between Lowenstein-Jensen medium (LJ) containing the following decontaminants and LJ alone: (i) PANTA ( n = 299), (ii) Selectatab-MB ( n = 299), and (iii) penicillin G ( n = 234). The contamination rate for LJ alone was approximately 31%, versus 5.0% for PANTA-containing, 2% for Selectatab-containing, and 9% for penicillin-containing media ( P < 0.001). M. tuberculosis isolation rates were 9.8%, 17%, 18%, and 12% for standard LJ, PANTA, Selectatab, and penicillin cultures, respectively.

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.

Mental disorders specifi cally associated with stress are exceptional in needing external events to have caused psychiatric symptoms for a diagnosis to be made. The specialty of stress-associated disorders is characterised by lively debates, including about the extent to which human suff ering should be medicalised, and the purported overuse of the diagnosis of post-traumatic stress disorder (PTSD). Most common mental disorders are potentiated or exacerbated by stress and childhood adversity. Moreover, the subjective narratives of many people with mental disorders emphasise such external events. Clinicians might inadvertently gravitate towards diagnoses of disorders specifi cally associated with stress whenever a signifi cant stressor can be identifi ed, because this approach provides a way to understand the person’s experience of symptoms, as a function of external events, that is more likely to be acceptable to the person. What could be missed in such formulations is that mental disorders specifi cally associated with stress are characterised not only by an antecedent event, but also by a distinct clinical picture with core symptoms that diff er from those of other mental disorders. WHO is developing the International Classifi cation of Diseases, version 11 (ICD-11), which is scheduled for approval in 2015. WHO is also responsible for the Mental Health Gap Action Programme (mhGAP), intended to assist with scaling up of mental health care, particularly in low-income and middle-income countries. It has launched the mhGAP intervention guide, which provides assessment and management protocols for selected conditions in non-specialised health-care settings. In response to requests from health-care providers, WHO is developing a module for this guide with disorders specifi cally associated with stress that will use proposed ICD-11 defi nitions. These activities are also relevant to WHO’s role in development of mental health policies related to humanitarian crises. Changes in the category of mental disorders specifi cally associated with stress are important because of questions about the validity of surveys showing a high rate of these diagnoses in populations who have experienced natural or man-made disasters, and about whether these diag noses are clinically useful in terms of leading to feasible and eff ective treatment. People with these disorders seek help in many health settings globally. The high level of overlap and co-occurrence with other mental disorders often challenges mental health specialists, while general medical services often note co-occurring somatic problems. The ICD-11 Working Group on this topic was asked to review scientifi c evidence and other information about use, clinical utility (as termed by WHO), and experience with relevant ICD-10 diagnoses in various health-care settings; to review proposals for the American Psychiatric Asso ciation’s Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) and consider how these may be suitable or useful for global applications; and to assemble proposals for ICD-11 with a focus on improving clinical utility. The Working Group has recommended a separate grouping of disorders specifi cally associated with stress for ICD-11, rather than combining them with anxiety disorders as in ICD-10 or DSM-IV. Disorders specifi cally associated with stress have two key characteristics: they are identifi able on the basis of diff erent psychopathology that is distinct from other mental disorders; and they arise in specifi c association with a stressful event or series of events. For each disorder in the grouping, the stressor is a necessary, although not suffi cient, causal factor. The stressor could range from negative life events within the normal range of experience (in the case of adjustment disorder) to traumatic stressors of exceptional severity (in the case of PTSD and complex PTSD). Among the controversies about existing formulations of PTSD are concerns about its overuse in populations exposed to natural or man-made disasters. One problem has been the application of the diagnosis when populations are still being actively exposed to extreme stressors—eg, continuing confl ict, uprooting to unsafe locations, or earthquake aftershocks—which makes differentiation between PTSD, adaptive fear reactions, and grief diffi cult, especially when the defi nition of PTSD includes non-specifi c symptoms. Moreover, there is a concern that an overemphasis on PTSD could contribute to clinicians failing to recognise other commonly occurring mental disorders, especially depression. Nonetheless, the appropriate use of a clearly defi ned PTSD category is one aspect of progress in evidencebased mental health care in humanitarian settings. The Working Group has recommended a refocus on the diagnosis of PTSD on three core elements, and removal of non-specifi c symptoms that are also part of other disorders. The proposed diagnostic guidelines need re-experiencing of the traumatic event, in which the event is not only remembered but experienced as occurring again; avoidance of reminders likely to produce re-experiencing of the traumatic event(s); and a perception of heightened current threat, as indicated by Lancet 2013; 381: 1683–85

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.

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.

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.

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.

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.

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.
