General population knowledge about extreme heat: a cross sectional survey in Lisbon and Madrid

Extreme heat is associated with an increased mortality and morbidity. National heat plans have been implemented to minimize the effect of extreme heat. The population’s awareness and knowledge of national heat plans and extreme heat is essential to improve the community’s behavior and adaptation. A general population survey was conducted in Lisbon and in Madrid to assess this knowledge. We used a questionnaire to interview passers-by. Results were compared between Lisbon and Madrid and between locals and foreigners, using Pearson Chi-square tests and Fisher's exact test. We conducted 260 interviews in six locations of different socio-economic backgrounds in each city. The most frequently mentioned extreme heat-related risk groups were the elderly (79.2%), children (49.6%) and babies (21.5%). The most frequently reported protective measures were increased fluid intake (73.1%) and avoiding exposure to the sun (50.8%). Knowledge about the heat plan was higher in Lisbon (37.2%) than in Madrid (25.2%) (p-value = 0.03). Foreigners had less knowledge of risk groups compared to locals. Heat plans were not widely known in Madrid and Lisbon. Nonetheless, knowledge of practical concepts to face extreme heat, such as certain risk groups and protective measures, was found. Our results were similar to comparable surveys where specific respondents’ groups were identified as less knowledgeable. This highlighted the importance of addressing these groups when communicating public health messages on heat. Foreigners should be specifically targeted to increase their awarenessinfo:eu-repo/semantics/publishedVersio

Tuberculous disseminated lymphadenopathy in an immunocompetent non-HIV patient: a case report

<p>Abstract</p> <p>Introduction</p> <p>In cases of patients with disseminated lymphadenopathy, the differential diagnosis has to include both benign and malignant causes, including sarcoidosis, metastatic disease, lymphoma and, although rarely present, tuberculosis. Tuberculosis is still one of the most frequently occurring infectious diseases worldwide. However, disseminated mycobacterial lymphadenitis is rare in immunocompetent patients.</p> <p>Case presentation</p> <p>We present the case of a 56-year-old Caucasian Greek male, who was immunocompetent and HIV negative, with a two-month history of recurring fever, loss of appetite and disseminated lymphadenopathy. The patient was diagnosed with mycobacterial lymphadenopathy.</p> <p>Conclusion</p> <p>This case highlights the need for suspicion in order to identify mycobacterial infection in patients with generalized lymphadenopathy, since misdiagnosis is possible and may lead to fatal complications for the patient.</p

Characterization of mesenchymal stem cells in pre-B acute lymphoblastic leukemia

Components of the bone marrow microenvironment (BMM) have been shown to mediate the way in which leukemia develops, progresses and responds to treatment. Increasing evidence shows that leukemic cells hijack the BMM, altering its functioning and establishing leukemia-supportive interactions with stromal and immune cells. While previous work has highlighted functional defects in the mesenchymal stem cell (MSC) population from the BMM of acute leukemias, thorough characterization and molecular profiling of MSCs in pre-B cell acute lymphoblastic leukemia (B-ALL), the most common cancer in children, has not been conducted. Here, we investigated the cellular and transcriptome profiles of MSCs isolated from the BMM of an immunocompetent BCR-ABL1+ model of B-ALL. Leukemia-associated MSCs exhibited reduced self-renewal capacity in vitro and significant changes in numerous molecular signatures, including upregulation of inflammatory signaling pathways. Additionally, we found downregulation of genes involved in extracellular matrix organization and osteoblastogenesis in leukemia-associated MSCs. This study provides cellular and molecular insights into the role of MSCs during B-ALL progression

Measuring mental health burden in humanitarian settings: a critical review of assessment tools

Background: The effects of disasters and conflicts are widespread and heavily studied. While attention to disasters’ impacts on mental health is growing, mental health effects are not well understood due to inconsistencies in measurement. Objective: The purpose of this study is to review mental health assessment tools and their use in populations affected by disasters and conflicts. Method: Tools that assess posttraumatic stress disorder, depression, substance use disorder, and general mental health were examined. This review began with a search for assessment tools in PubMed, PsycINFO, and Google Scholar. Next, validation studies for the tools were obtained through snowball sampling. A final search was conducted for scientific studies using the selected tools in humanitarian settings to collect the data for analysis. The benefits and limitations described for each tool were compiled into a complete table. Results: Twelve assessment tools were included, with 88 studies using them. The primary findings indicate that half of the studies used the Impact of Events Scale-Revised. The most common limitation discussed is that self-report tools inaccurately estimate the prevalence of mental health problems. This inaccuracy is further exacerbated by a lack of cultural appropriateness of the tools, as many are developed for Western contexts. Conclusion: It is recommended that researchers and humanitarian workers reflect on the effectiveness of the mental health assessment tool they use to accurately represent the populations under study in emergency settings. In addition, mental health assessment should be coupled with action

Heatwave preparedness in urban Georgia: A street survey in three cities

Background: The frequency and intensity of heatwaves are expected to increase in the coming years. To promote resilient cities, it is key to have insights in populations with low preparedness levels. This study investigated personal characteristics associated with heatwave-protective knowledge, and preferred information channels and sources on this topic in cities in Georgia. Methods: We undertook a street survey among three large cities in Georgia, including the capital Tbilisi. We collected demographic, socio-economic, medical and behavioural characteristics as potential risk factors for reduced heatwave-protective knowledge. Furthermore, we asked respondents about information channels and sources they use and prefer to obtain information on heatwave-protective measures. Results: Being male, parent of children under the age of 12 and having a lower educational level are risk factors for lower knowledge levels on heatwave protection. Being homemakers, retiree, having fasted and using medication are protective factors. Television and internet are the channels more often used for obtaining in-formation on heatwave-protective measures, and people prefer to receive information on this topic from health authorities. Conclusion: Our findings identified characteristics that make people more vulnerable to heatwaves, due to a reduced knowledge level on heatwave protection. Targeted communication towards these groups, using infor-mation sources and media specifically aimed at this target audience, could improve this

Predictors of exceeding emergency under-five mortality thresholds using small-scale survey data from humanitarian settings (1999 – 2020): considerations for measles vaccination, malnutrition, and displacement status

Background: Quantifying the effect of measles containing vaccine (MCV) coverage and the prevalence of global acute malnutrition (GAM) on mortality levels in populations of displaced and crisis-affected resident children is important for intervention programming in humanitarian emergencies. Methods: A total of 1597 surveys containing data on under-five death rate, population status (internally displaced, refugee, or crisis-affected resident), measles containing vaccine coverage, and global acute malnutrition were extracted from the Complex Emergency Database (CE-DAT). Under-five mortality rates were dichotomized to those exceeding critical levels or otherwise. A Bayesian multivariable mixed-effect logistic regression model was used to assess the association between an under-five death rate (U5DR) exceeding this threshold and population status (i.e., internally displaced, refugees or residents), GAM prevalence (proxy for food security), and MCV coverage. Results: The prevalence of GAM, MCV and U5DR were higher in internally displaced children (IDC) with values of 14.6%, 69.9% and 2.07 deaths per 10 000 per day, respectively. Refugee populations had lower average under-five mortality rate (0.89 deaths per 10 000 per day), GAM of 12.0% and the highest measles containing vaccine coverage (80.0%). In crisis-affected residents the prevalence of GAM, MCV and average U5DR are 11.1%, 65.5% and 1.20 deaths per 10 000 per day respectively. In mixed-effect logistic model taking 2 deaths per 10 000 children less than five years old per as emergency threshold (Model III); MCV (AOR = 0.66, 95% Highest Density Interval (HDI): 0.57, 0.78), GAM (AOR = 1.79, 95% HDI: 1.52, 2.12) were associated with a reduction of the odds of U5DR exceeding critical level accounting for country-specific levels of variability. The odds of U5DR exceeding critical level (2/10000/day) in crisis-affected resident children and refugees were 0.36 (95% HDI: 0.22, 0.58) and 0.25(95% HDI: 0.11, 0.55) less than amongst IDP children adjusting for GAM and MCV. In considering country specific yearly median U5DR (model IV) the odds of U5DR exceeding twice the median U5DR were associated with MCV (AOR = 0.72, 95% HDI: 0.64, 0.82), GAM (AOR = 1.53, 95%HDI: 1.34, 1.76). The odds of U5DR exceeding critical level in crisis-affected resident children was 0.30(95% HDI: 0.20, 0.45) less than IDP children, after adjusting for MCV and GAM. We found no difference between the odds of U5DR exceeding twice the country level median U5DR in the refugee population compared to the IDPs. Conclusions: In this study vaccination coverage and global acute malnutrition (proxy for food security) were associated with U5DR exceeding critical level. The emergency threshold for IDPs and affected residents is significantly different and consistent across the different outcomes, whereas the result is inconsistent for IDPs and refugees. Continued improvement in measles vaccination coverage and reduction of malnutrition in humanitarian emergencies have the potential to minimize the deterioration of mortality level amongst children in emergency settings. To generate a robust understanding of the critical level of child mortality in displaced and affected resident populations, studies accounting for the impact of the duration of displacement, contextual factors in humanitarian settings, and the level of humanitarian assistance provided are needed

The impact of Typhoon Haiyan on admissions in two hospitals in Eastern Visayas, Philippines

We investigated the short-term impact of Typhoon Haiyan, one of the strongest typhoons ever to make landfall, on the pattern of admissions in two hospitals in Eastern Visayas, the Philippines.This study took place at Eastern Visayas Regional Medical Center (EVRMC) in Tacloban, and Ormoc District Hospital (ODH) in Ormoc. We determined whether there were differences in the pattern of admissions between the week before and the three weeks after Haiyan by using information on sex, age, diagnosis, ward and outcome at discharge from patient records.There was a drop in admissions in both hospitals after Haiyan as compared to before. Admissions climbed back to the baseline after ten days in EVRMC and after two weeks in ODH. When comparing the period after Haiyan to the period before, there was a relative increase in male versus female admissions in ODH (OR 2.8, 95%CI 1.7-4.3), but not in EVRMC. Patients aged ≥50 years and 0-14 years had the highest relative increase in admissions. There was a relative decrease in admissions for the ICD10 group 'Pregnancy, childbirth and the puerperium' (OR 0.4, 95%CI 0.3-0.6), and an increase in 'Certain infectious and parasitic diseases' (OR 2.1, 95%CI 1.2-3.5), mainly gastroenteritis, and 'Diseases of the respiratory system' (OR 1.8, 95%CI 1.0-3.0), mainly pneumonia, compared to all other diagnosis groups in ODH. Out of all reasons for admission within the study period, 66% belong to these three ICD-10 groups. Data on reasons for admission were not available for EVRMC.The observed reduction in patients after the Typhoon calls for ensuring that hospital accessibility should be protected and reinforced, especially for pregnant women, by trying to remove debris in the direct hospital vicinity. Hospitals in areas prone to tropical cyclones should be prepared to treat large numbers of patients with gastroenteritis and pneumonia, as part of their disaster plans

Impact of mass vaccination campaigns on measles transmission during a nationwide outbreak in Guinea, 2017

Objective: To estimate the time-dependent measles effective reproduction number (Rt)as an indicator of the impact of three outbreak response vaccination (ORV) campaigns on measles transmission during a nationwide outbreak in Guinea. Methods: Rt represents the average number of secondary cases generated by a single primary case in a partially immune population during a given time period. Measles Rt was estimated using daily incidence data for 3,952 outbreak-associated measles cases in Guinea in 2017 for the time periods prior to, between, and following each of three ORV campaigns using a simple and extensible mathematical model. Results: Rt was estimated to be above the threshold value of 1 during the initial growth period of the outbreak until the first ORV campaign began on March 13 (Rt =1.60, 95% CI: 1.55–1.67). It subsequently dropped below 1 and remained < 1 through the end of the year (range: 0.71–0.91), although low levels of transmission persisted. Conclusions: Reduction in Rt coincided with implementation of the ORV campaigns, indicating success of the campaigns at maintaining measles transmission intensity below epidemic growth levels. However, persistent measles transmission remains an issue in Guinea due to insufficient levels of herd immunity. Estimation of Rt should be further leveraged to help decision makers and field staff understand outbreak progress and the timing and type of vaccination efforts needed to halt transmission

Hospital Resilience After the 2015 Earthquake in Nepal: Results From Semi-structured Interviews With Hospital Staff

Background: Resilient hospitals are increasingly recognized as a cornerstone of disaster reduction in global policies such as the Sendai Framework for Action. However, current hospital resilience frameworks emerged from pre-disaster conceptualizations, and have not been verified in real-life disaster contexts nor in the frontlines. Our aim was to study a tertiary hospital’s resilience after the 2015 earthquake in Nepal, as experienced by its staff. Methods: We undertook a qualitative study in the Tribhuvan University Teaching Hospital (TUTH), where we conducted 18 semi-structured interviews with hospital staff. We inductively created themes to describe the earthquake burden to the hospital, and to analyze individual resilience of hospital staff. In addition, we deductively documented the resilience of the hospital as a system, according to the system resilience dimensions: means of resilience (redundancy and resourcefulness), and ends of resilience (robustness and rapidity). Results: In terms of robustness, TUTH increased its capacity for earthquake victims as elective activities were temporarily interrupted and quality of care was not a priority. Three stages of rapidity were identified: critical rapidity to address immediate needs, stabilizing rapidity until the hospital re-started routine activities, and recovery rapidity. In addition to the disaster plan, emerging adaptations played amajor role in redundancy and resourcefulness. We found that individual resilience depended on three determinants: safety, meaningfulness, and sense of belonging. Conclusions: Hospital resilience results from a complexity of emerging and planned adaptations, as well as from interdependencies with individual resilience. Frameworks and plans to improve hospital resilience must reflect flexibility of response, and a concern for well-being of hospital staff is central for sustainable disaster response and improved resilience
