[Pathologies of the immigrant child in the Intensive Care Unit. Update]. / Patologías del niño inmigrante en la Unidad de Cuidados Intensivos. Actualización.

It is increasingly common to provide medical care in the Intensive Care Unit (ICU) for immigrant children and adolescents as well as those born in Chile with parents in such condition. Currently, this has caused that the health team has to face diverse infrequent pathologies in our country and/ or diagnostic problems derive from the poor knowledge of genetic conditions of this population, some resulting from their health conditions. This review addresses several aspects of hematological, infectious, parasitic, respiratory, and cardiovascular pathologies, all relevant topics to know during their stay in the ICU. It is a duty of the health team to be updated on pathologies of low prevalence in our country, some of them very little known until a decade ago, but which are currently increasingly present in the ICUs of the Chilean public health system.

Comparison of New Liquid Chromatography-Mass Spectrometry Method and Enzyme-Multiplied Immunoassay Technique for Routine Therapeutic Drug Monitoring of Vancomycin in Chinese Patients.

BACKGROUND: Therapeutic drug monitoring of vancomycin is very valuable due to the good correlation between trough levels and clinical outcome. Therefore, it is important to accurately determine the concentration of vancomycin in patient plasma for adequate dose-adjustment. The objective of this study was to develop a new liquid chromatography-mass spectrometry (LC-MS) method for determination of vancomycin in patient plasma and compare the results with those obtained from enzyme-multiplied immunoassay technique (EMIT). METHODS: After extraction by simple protein precipitation, vancomycin and bergenin (internal standard) were separated on a C18 column (150×4.6 mm, 5 µm) at 40°C by gradient elution with 0.1% formic acid and acetonitrile as the mobile phase and measured by electrospray ionization source in positive selective ion monitoring mode. Seventy-nine plasma samples from patients with severe infection were analyzed by enzyme-multiplied immunoassay technique and LC-MS method. MedCalc 15.2 software with Bland-Altman analysis and Passing-Bablok regression analysis was used for statistical analysis. RESULTS: The weighted (1/x2) calibration curve of the validated LC-MS was linear within the concentration range of 0.25 - 40 µg/mL. The inter- and intra-day precisions (%RSD) were less than 10.0%. No significant matrix effect was observed in the relevant time ranges. Comparison of the two methods indicated that results of the LC-MS were close to that of EMIT with a correlation coefficient of 0.957. Upon Bland-Altman analysis, the bias amounted to 2.9 µg/mL (95% confidence intervals of -3.4 - 9.2 µg/mL). CONCLUSIONS: The established LC-MS method and EMIT were both suitable for routine TDM of vancomycin.

Association of serious infections with pemphigus and pemphigoid: analysis of the Nationwide Inpatient Sample.

BACKGROUND: Pemphigus and pemphigoid are blistering disorders associated with barrier disruption, immune dysregulation and use of immunosuppressing systemic therapy, all of which may predispose towards serious infections. OBJECTIVES: To determine whether pemphigus and pemphigoid are associated with increased likelihood of serious infections and the impact of such infections on mortality and cost of care. METHODS: We analysed data from the 2002 to 2012 Nationwide Inpatient Sample, including a representative 20% sample of all hospitalizations in the US (total n = 72 108 077 adults). RESULTS: Overall, 54.6% (95% CI: 53.6-55.6%) and 50.4% (49.0-51.8%) of inpatients with either pemphigoid or pemphigus had a diagnosis of serious infection, respectively, compared with 25.4% (25.2-25.6%) in those without either diagnosis. In multivariable logistic regression models controlling for gender, age, race/ethnicity and insurance status, pemphigoid or pemphigus was associated with 26 or 21 of 48 infections examined, respectively. In particular, both pemphigoid and pemphigus were associated with higher odds of infections of the skin, bones, respiratory, gastrointestinal, genitourinary and central nervous system, septicaemia and antibiotic-resistant infections. Pemphigus was also associated with aspergillus, pharyngitis and Pneumocystis Carinii pneumonia. Associations of any serious infection in both pemphigoid and pemphigus patients were older age, non-White race, lower median household income, government or no insurance, higher number of chronic conditions, and those with a diagnosis of Cushing's syndrome, diabetes, cancer or autoimmune disease. The diagnosis of any serious infection vs. no infection was associated with increased inpatient mortality and costs in both pemphigoid (mortality: 7.85% vs. 2.84%; cost: $16 115 vs. $10 653) and pemphigus (mortality: 6.78% vs. 1.88%; cost: $17 707 vs. $11 545) inpatients (P < 0.0001 for all). CONCLUSIONS: Adults with pemphigus or pemphigoid had increased cutaneous, respiratory, multi-organ and systemic infections, which were associated with considerable inpatient mortality and cost burden. Moreover, there were significant clinical and healthcare disparities with respect to infections in patients with pemphigus or pemphigoid.

Infection-related mortality in Hispanic and non-Hispanic children with cancer.

BACKGROUND: Hispanic children with cancer experience poorer survival than their White counterparts. Infection is a known cause of cancer-related mortality; however, little is known about the risk of infection-related death among Hispanic children with cancer. We examine the association of Hispanic ethnicity with infection-related mortality and life-threatening events among children with cancer. PROCEDURE: For a cohort of all pediatric cancer patients diagnosed from 1986 to 2012 and treated at a single tertiary care center, we obtained national death records to determine all-cause mortality and infection-related mortality, as well as intensive care unit (ICU) admissions as a surrogate for life-threatening events. Cox proportional hazard models assessed all-cause mortality and infection-related mortality using ethnicity as the main independent variable. ICU admission rates were modeled using a zero-inflated Poisson regression model. Models were adjusted for gender, diagnosis year, age, residential location, and diagnosis. RESULTS: Of 6,198 patients, 741 (12%) were Hispanic. Mean follow-up was 11 years (SD = 8.04). There were 1,205 deaths, with 193 attributable to infection. Differences in all-cause mortality between Hispanic and non-Hispanic patients did not reach significance (hazard ratio [HR] = 1.14, 95% confidence interval [CI]: 0.96-1.36). However, Hispanic patients were 68% (HR = 1.68, 95% CI: 1.16-2.43) more likely to have an infection-related cause of death. Hispanic ethnicity was statistically associated with a higher rate of ICU admissions (rate ratio = 1.32, 95% CI: 1.12-1.56). CONCLUSION: Hispanic pediatric cancer patients were more likely to have an infection-related death and higher rates of ICU admissions than non-Hispanic patients. Infection may be an overlooked contributor to poorer outcomes among Hispanic patients.

[Mortality of immigrants in Tuscany Region (Central Italy), 1997-2013]. / Mortalità della popolazione immigrata in Toscana dal 1997 al 2013.

OBJECTIVES: to evaluate mortality in immigrants dwelling in Tuscany Region (Central Italy) compared to mortality data relating to the Italian population residing in the same region. DESIGN: cross-sectional descriptive mortality study relying on a unique data source, i.e., the Regional Mortality Registry of Tuscany, for the period 1997-2013. SETTING AND PARTICIPANTS: in the analysis, immigrants residing in Tuscany were included; Italian residing in the same region were the comparison population. Immigrants were divided into two categories: immigrants from Countries at High Migration Rates (CHMRs) and immigrants from Developed Countries (DCs). MAIN OUTCOME MEASURES: proportional general and cause-specific mortality by age and gender for the period 1997-2013; trends of standardized truncated (age 20-64) mortality rates for the Italian population, and for immigrants from CHMRs and from DCs for the period 2002-2013; standardized mortality ratios (SMRs) in people from CHMRs with confidence interval at 95% (95%CI) for all causes and cause-specific mortality. RESULTS: during 1997-2013, 4,681 deaths were recorded among immigrants, 3,005 of which were in immigrants from a CHMR. Both cause-specific and general mortality trends in Italians and in immigrants from DCs are lowering, while general mortality of immigrants from CHMRs seems to have risen in the last 5 years. Mortality of people from CHMRs for all causes, cardiovascular causes, and cancer is permanently lower than Italian population's mortality in the examined period, but the gap seems to progressively reduce. On the other hand, child mortality among immigrants from CHMRs, despite a declining trend, is consistently higher than Italian population's mortality. Following the SMR analysis, the only exceeding cause of mortality in people from CHMRs - compared to the Italian population - is homicide among men (SMR: 3.46; 95%CI 1.55-5.59). CONCLUSIONS: this study updates our knowledge on immigrants' mortality - and, indirectly, on their health status - in Tuscany. The gap between mortality of Italians and immigrants from CHMRs is reducing: this could be partially explained by a successful ongoing integration process. For future analyses, it would be important to obtain more complete data relative to non-resident immigrants' mortality, as their number is constantly increasing.

Socioeconomic and Demographic Factors Influencing Feeding Practices, Morbidity Status, and Dietary Intakes of Children Aged 7-24 Months in Rural Uganda.

The objective of this study was to analyze the nutritional and morbidity patterns of children aged 7-24 months in relationship to household socioeconomic and demographic characteristics. Structured questionnaires and repeated 24-hour recalls were used to collect data. Maternal education and age influenced timing of complementary foods, dietary diversity score, meal frequency, and diarrhea incidences (p < .05). This resulted in 53%, 59%, 48%, 43%, and 22% of the study children having inadequate intake of energy, protein, vitamin A, iron, and zinc, respectively. Households need to be empowered to utilize available resources for improving nutrient intake and health among their children.

Collaborating with a social housing provider supports a large cohort study of the health effects of housing conditions.

BACKGROUND: Despite the importance of adequate, un-crowded housing as a prerequisite for good health, few large cohort studies have explored the health effects of housing conditions. The Social Housing Outcomes Worth (SHOW) Study was established to assess the relationship between housing conditions and health, particularly between household crowding and infectious diseases. This paper reports on the methods and feasibility of using a large administrative housing database for epidemiological research and the characteristics of the social housing population. METHODS: This prospective open cohort study was established in 2003 in collaboration with Housing New Zealand Corporation which provides housing for approximately 5% of the population. The Study measures health outcomes using linked anonymised hospitalisation and mortality records provided by the New Zealand Ministry of Health. RESULTS: It was possible to match the majority (96%) of applicant and tenant household members with their National Health Index (NHI) number allowing linkage to anonymised coded data on their hospitalisations and mortality. By December 2011, the study population consisted of 11,196 applicants and 196,612 tenants. Half were less than 21 years of age. About two-thirds identified as Maori or Pacific ethnicity. Household incomes were low. Of tenant households, 44% containing one or more smokers compared with 33% for New Zealand as a whole. Exposure to household crowding, as measured by a deficit of one or more bedrooms, was common for applicants (52%) and tenants (38%) compared with New Zealanders as whole (10%). CONCLUSIONS: This project has shown that an administrative housing database can be used to form a large cohort population and successfully link cohort members to their health records in a way that meets confidentiality and ethical requirements. This study also confirms that social housing tenants are a highly deprived population with relatively low incomes and high levels of exposure to household crowding and environmental tobacco smoke.

[Asylum-seekers' mental and physical health problems: practices and recommendations]. / A menedékkérok mentális és fizikai egészségproblémái: gyakorlatok és ajánlások.

The Hungarian health care system faces new challenges with the unprecedented increased rate of migration. Asylum-seekers arriving are a heterogeneous group. Their health care needs vary depending on their country of origin and the quality of the health care they received prior to arrival, not to mention the impact of the migration process on their health. Described within this paper are the challenges an asylum seeker might face in obtaining care on arrival into the host country and the challenges clinicians face in providing that care. This review is designed to give health professionals the necessary knowledge to care for asylum-seekers in a culturally aware and clinically informed manner.

Mortality in adult immigrants in the 2000s in Belgium: a test of the 'healthy-migrant' and the 'migration-as-rapid-health-transition' hypotheses.

OBJECTIVE: Firstly, to map out and compare all-cause and cause-specific mortality patterns by migrant background in Belgium; and secondly, to probe into explanations for the observed patterns, more specifically into the healthy-migrant, acculturation and the migration-as-rapid-health-transition theories. METHODS: Data comprise individually linked Belgian census-mortality follow-up data for the period 2001-2011. All official inhabitants aged 25-54 at time of the census were included. To delve into the different explanations, differences in all-cause and chronic- and infectious-disease mortality were estimated using Poisson regression models, adjusted for age, socioeconomic position and urbanicity. RESULTS: First-generation immigrants have lower all-cause and chronic-disease mortality than the host population. This mortality advantage wears off with length of stay and is more marked among non-Western than Western first-generation immigrants. For example, Western and non-Western male immigrants residing 10 years or more in Belgium have a mortality rate ratio for cardiovascular disease of 0.72 (95% CI 0.66-0.78) and 0.59 (95% CI 0.53-0.66), respectively (vs host population). The pattern of infectious-disease mortality in migrants is slightly different, with rather high mortality rates in first-generation sub-Saharan Africans and rather low rates in all other immigrant groups. As for second-generation immigrants, the picture is gloomier, with a mortality disadvantage that disappears after control for socioeconomic position. CONCLUSION: Findings are largely consistent with the healthy-migrant, acculturation and the migration-as-rapid-health-transition theories. The convergence of the mortality profile of second-generation immigrants towards that of the host population with similar socioeconomic position indicates the need for policies simultaneously addressing different areas of deprivation.

Dysplasia features of myelodysplastic syndrome in ethnically Chinese people.

OBJECTIVE: It was our aim to study the diagnostic significances of various dysplasia characteristics in myelodysplastic syndrome (MDS). METHODS: We analyzed 160 cases of primary MDS and a control group including 28 cases of paroxysmal nocturnal hemoglobinuria (PNH), 104 cases of idiopathic thrombocytopenic purpura (ITP), 53 cases of non-severe aplastic anemia (NSAA), 40 cases of megaloblastic anemia and 50 cases of infectious and autoimmune diseases. Peripheral blood smears and bone marrow morphology were reviewed. RESULTS: There was no significant difference in the occurrence rates of a variety of dysplasias in three lineages among MDS, megaloblastic anemia and PNH; however, changes in qualities and quantities in three lineages between NSAA and MDS were significantly different. ITP and MDS showed statistical differences in multiple changes in myeloid and erythroid cells. Significant differences also existed in multiple changes in erythroid series and megakaryocytes between infectious and autoimmune diseases and MDS. Morphological abnormalities highly related with MDS included multinucleated erythroblasts, ringed sideroblasts, poikilocytosis and gigantocytes, pseudo-Pelger neutrophils, ring-shaped nucleus, and micromegakaryocytes. CONCLUSIONS: It is difficult to discriminate megaloblastic anemia and PNH from MDS by means of cell morphology. Different dysplasias of MDS have specific diagnostic values.

Tertiary paediatric refugee health clinic in Western Australia: analysis of the first 1026 children.

AIM: Children account for approximately half of the humanitarian refugees currently resettled in Australia. A multidisciplinary refugee health clinic (RHC) was established at the tertiary paediatric hospital in Western Australia to address burgeoning referrals of refugee children following voluntary post-resettlement health assessment. The aim of this study is to describe the epidemiology of common conditions in resettled paediatric refugees attending a tertiary multidisciplinary RHC. METHODS: Standardised clinical and demographic data were routinely collected during first visit clinical assessment at the RHC. Descriptive analyses of the first 1026 children are presented. RESULTS: One thousand twenty-six refugee children from 475 families and over 30 different ethnicities were described. Nine hundred twenty-seven (90.4%) children were referred following post-resettlement health assessment. Median age was 7.8 years. Common reasons for referral were: vitamin D deficiency (400, 39%), iron deficiency (226, 22%), positive Helicobacter pylori serology (206, 21%), poor appetite (175, 17.1%), and schistosomiasis (170, 16.6%). Comorbidities identified by the RHC included tinea capitis and corporis (297, 28.9%), and dental disease (228, 22.2%). Two-thirds of children (680, 66.3%) had at least one abnormal finding on clinical examination that identified pathologies that were not evident from the history. Three hundred eighty children (37%) were referred to sub-specialty services. CONCLUSIONS: A multidisciplinary paediatric RHC facilitated and strengthened the management of refugee children with multiple and complex health needs. Evidenced-based culturally appropriate methods to identify developmental delay, psychological morbidity and quantify social needs of this vulnerable population remain uncertain. These findings are relevant to the continuing evolution of paediatric refugee health care in Australia and other high income countries.

Might infection explain the higher risk of coronary heart disease in South Asians? Systematic review comparing prevalence rates with white populations in developed countries.

OBJECTIVES: South Asians in developed countries such as the UK are at comparatively high risk of coronary heart disease for reasons which are not fully understood. One unexplored hypothesis is more infections in this ethnic group. This study assessed whether the prevalence of infections among South Asians differs from that among White populations of European origin in developed countries. STUDY DESIGN: Systematic review. METHODS: Medline, Web of Science and Google Scholar databases were searched. In addition, reference lists and citations were reviewed. RESULTS: Twenty-one studies reported prevalence rates and mean antibody levels of infection with 17 different pathogens or non-specific markers of infection. Among bacterial infections, higher rates of Escherichia coli and Mycobacterium tuberculosis infection were found in South Asians. No consistent differences were found for periodontal pathogens, Helicobacter pylori, Staphylococcus aureus, Chlamydia pneumoniae and Mycobacterium avium. For viral pathogens, higher rates of hepatitis A, hepatitis B and cytomegalovirus; and lower rates of herpes simplex, hepatitis C, human immunodeficiency virus and varicella zoster virus were found among South Asians. No difference was seen in the prevalence of hepatitis G virus in South Asians. Levels of non-specific markers of infection (total immunoglobulin G, endotoxin) were higher in South Asians. CONCLUSIONS: The number of studies was small. Differences in the prevalence of specific infections were found, but the current evidence is insufficient to support or reject the hypothesis under examination. Further studies are warranted.

Association of allergic sensitization with infectious diseases burden in Roma and non-Roma children.

The hypothesis whether exposure to certain infections protects from atopy remains equivocal. To further investigate this, we compared serologic markers of infection and allergic sensitization prevalence in Roma children, who live under unfavorable hygienic conditions that facilitate the spread of infections, and non-Roma children who live in the same area. Analyses included 98 Roma and 118 non-Roma children. Serum IgG antibodies for 13 foodborne- airborne- and bloodborne infectious agents were determined, and a cumulative index of exposure was calculated by adding one point for each positive infection. Specific serum IgE to certain common food- and aero-allergens was also tested. and positivity to any of them was defined as indication of atopy. Roma children were found significantly more seropositive for T. gondii, Hepatitis A, H. pylori, HSV-1, CMV, and Hepatitis B (p < 0.0001). Non-Roma children were found more seropositive for RSV and M. pneumonia (p < 0.0001). Regarding the overall prevalence of atopy or the specific IgE responses to the allergens tested, no statistically significant differences were found between Roma and non-Roma children. A positive association of the cumulative index of exposure to infections with atopy was found in the non-Roma children (OR: 1.38, 95% CI: 1.08-1.75, p = 0.01) and in the total population (OR: 1.42, 95% CI: 1.11-1.83, p = 0.01). Regarding the specific infectious agents tested, a statistically significant positive association of atopy with seropositivity was found for M. pneumoniae in the non-Roma children (OR: 3.93, 95% CI: 1.39) as well as in the total population studied (OR: 2.83, 95% CI: 1.32-6.07, p = 0.01). Despite the higher burden of exposure to the battery of the infectious agents tested among Roma children, no protective effect for allergic disease development was evident. On the contrary, a positive association of exposure to infections with evidence of atopy was found, especially evident in the non-Roma children.

CCR5Δ32 in Brazil: Impacts of a European Genetic Variant on a Highly Admixed Population.

The genetic background of Brazilians encompasses Amerindian, African, and European components as a result of the colonization of an already Amerindian inhabited region by Europeans, associated to a massive influx of Africans. Other migratory flows introduced into the Brazilian population genetic components from Asia and the Middle East. Currently, Brazil has a highly admixed population and, therefore, the study of genetic factors in the context of health or disease in Brazil is a challenging and remarkably interesting subject. This phenomenon is exemplified by the genetic variant CCR5Δ32, a 32 base-pair deletion in the CCR5 gene. CCR5Δ32 originated in Europe, but the time of origin as well as the selective pressures that allowed the maintenance of this variant and the establishment of its current frequencies in the different human populations is still a field of debates. Due to its origin, the CCR5Δ32 allele frequency is high in European-derived populations (~10%) and low in Asian and African native human populations. In Brazil, the CCR5Δ32 allele frequency is intermediate (4-6%) and varies on the Brazilian States, depending on the migratory history of each region. CCR5 is a protein that regulates the activity of several immune cells, also acting as the main HIV-1 co-receptor. The CCR5 expression is influenced by CCR5Δ32 genotypes. No CCR5 expression is observed in CCR5Δ32 homozygous individuals. Thus, the CCR5Δ32 has particular effects on different diseases. At the population level, the effect that CCR5Δ32 has on European populations may be different than that observed in highly admixed populations. Besides less evident due to its low frequency in admixed groups, the effect of the CCR5Δ32 variant may be affected by other genetic traits. Understanding the effects of CCR5Δ32 on Brazilians is essential to predict the potential use of pharmacological CCR5 modulators in Brazil. Therefore, this study reviews the impacts of the CCR5Δ32 on the Brazilian population, considering infectious diseases, inflammatory conditions, and cancer. Finally, this article provides a general discussion concerning the impacts of a European-derived variant, the CCR5Δ32, on a highly admixed population.

What is the qualitative evidence concerning the risks, diagnosis, management and consequences of gastrointestinal infections in the community in the United Kingdom? A systematic review and meta-ethnography.

BACKGROUND: Gastrointestinal (GI) infections cause a significant public health burden worldwide and in the UK with evidence pointing to socio-economic inequalities, particularly among children. Qualitative studies can help us understand why inequalities occur and contribute to developing more effective interventions. This study had two aims: 1. Conduct a systematic review to determine the extent and nature of UK qualitative evidence on gastrointestinal infections; 2. Use meta-ethnography to examine the influences of the differing social contexts in which people live. METHODS: MEDLINE, Scopus, Web of science, CINAHL and JSTOR were searched for UK qualitative studies engaging with the risk, diagnosis, management or consequences of gastrointestinal infections from 1980 to July 2019. Five reviewers were involved in applying inclusion and exclusion criteria, extracting and synthesising data (PROSPERO CRD 42017055157). RESULTS: Searches identified 4080 studies, 18 met the inclusion criteria. The majority (n = 16) contained data relating to the risk of gastrointestinal infection and these made up the main synthesis. The tenets of meta-ethnography were used to glean new understandings of the role of social and environmental contexts in shaping the risk of gastrointestinal infection, specifically with respect to foodborne GI illness. Three main explanations concerning risk emerged from the data: explanations of risk in the community were underpinned by understandings of 'bugs', dirt and where food comes from; risks were negotiated in households alongside diverse processes of decision making around food; and resources available to households shaped food practices. CONCLUSION: This systematic review highlights the scarcity of UK qualitative evidence examining gastrointestinal infections. Apart from risk, questions around diagnosis, management and consequences of illness were largely untouched. No studies investigated patterning by socio-economic status. Nevertheless, the meta-ethnography yielded wider contextual theories and explanations as to why people might not follow food hygiene guidance, giving pointers to the types of qualitative enquiry needed to develop more effective interventions.

Infection Prevention and Control Lead Link Practitioner: a new deployed role piloted on Exercise SAIF SAREEA 3.

Disease non-battle injury has plagued British expeditionary forces through the ages. While in recent years significant mortality has reduced, it has had a large impact on operational effectiveness, at times leading to closure of major medical treatment facilities (MTFs).Infection Prevention and Control (IPC) benefits from a subject matter expert and champion to ensure it remains at the front of people's minds and to be on hand to manage acute and dynamic situations. To mitigate the lack of an IPC Nursing Officer, we piloted a deployed military IPC Lead Link Practitioner (IPC-LL) for the first time on a large-scale overseas exercise (SAIF SAREEA 3). An experienced generalist nurse deploying as the IPC-LL (after specific training) provided pre-deployment IPC education and preparation, deployed IPC advice, undertook mandatory audits and monitored IPC compliance throughout the MTFs on the exercise. Data from 22 IPC audits conducted on the exercise showed that the presence of the IPC-LL improved IPC compliance and standards overall in the MTF where based, compared with others. In addition, a gastroenteritis outbreak occurred and was successfully managed with significant input from the IPC-LL. The IPC-LL was also able to add value by pre-empting potential IPC problems from occurring.There is a small pool of deployable Infection Prevention and Control Nursing Officers, so this new IPC-LL role could help to fill the capability gap. The IPC-LL could be the dedicated person focusing on IPC elements, reducing the IPC risk within the deployed field hospital setting where deployed experts are not available.

Vulnerability to drug-related infections and co-infections among injecting drug users in Budapest, Hungary.

BACKGROUND: Drug-related infectious diseases are among the major health consequences of drug use, and any existing drug-related infection may predispose injecting drug users (IDUs) to other infections. METHODS: We assessed among IDUs in Budapest, Hungary the prevalence of and vulnerability to selected drug-related infections and co-infections. The sample consisted of 186 participants recruited between October 2005 and December 2006. RESULTS: We found 0% HIV, 37% HCV, 24% HAV, and 14% past HBV infection. Infections with Herpes 1 or 2, tuberculosis, Chlamydia, syphilis, and gonorrhoea were 79%, 12%, 7%, 4%, and 0%, respectively. Co-infection with HAV/HCV was 12%, HBV/HCV 9%, HAV/HBV 7%, and HAV/HBV/HCV 4%. Those over age 30, the ethnic Roma, and the homeless were more likely to have any hepatitis and a higher number of drug-related infections. Amphetamine injectors were more likely to have a higher number of drug-related infections and those who travelled within Hungary were more likely to have any STI. However, those who worked at least part time and those who were in treatment were less likely to have drug-related infections. CONCLUSIONS: These results highlight the need of interventions in Hungary to reach and focus on marginalized (Roma or homeless) IDUs and address not only injecting and sex risk, but also hygienic living and injecting conditions. Furthermore, structural interventions to increase social integration (working or being in treatment) may improve welfare and decrease drug use and infection risk tied to drug use/injection among disadvantaged, marginalized, mostly minority populations.

[Analysis of the epidemiological profile of the indigenous community of Hueyapan, Morelos]. / Análisis del perfil epidemiológico de la comunidad indígena de Hueyapan, Morelos.

BACKGROUND: The epidemiological transition is a phenomenon that has had a different impact between urban and rural settings. The WHO points out that the population with the lowest socioeconomic status is the most adversely affected for the unequal distribution of resources, indigenous people are a part of this population. OBJECTIVE: To analyze the epidemiological profile of the indigenous people of Hueyapan, Morelos during the months of March to June 2017. METHODS: A cross-sectional epidemiological study was carried out in the indigenous community of Hueyapan, belonging to the municipality of Morelos, in 2017. A sample of 338 households was calculated; as inclusion criteria, those dwellings where the age of residence in Hueyapan was equal to or greater than four years were taken; a systematic sampling was carried out every three households, in addition, Mexico's INEGI and Health Department databases were analyzed from 2011 to 2015. RESULTS: In relation to morbidity, an upward trend was found in the crude rate, from 119.7 per 1,000 in 2011 to 270.7 per 1000 in 2015, among the most prevalent diseases in those years, infectious diseases were identified as major and the appearance of noncommunicable diseases began to be observed. In relation to mortality, a linear trend was observed in the crude rate of 5.7 per 1000 in 2011 to 6.6 per 1000 in 2015. CONCLUSIONS: The epidemiological profile of Hueyapan coincides with a process of epidemiological transition where there is a double burden of disease. This suggests a challenge for the public health area that should be addressed from the creation of health strategies, programs and policies aimed at this population from an intercultural approach.

INTRODUCCIÓN: la transición epidemiológica es un fenómeno que se ha presentado de forma distinta entre sectores urbanizados y rurales. OBJETIVO: analizar el perfil epidemiológico de la comunidad indígena de Hueyapan, Morelos, durante el periodo de marzo a junio de 2017. MÉTODOS: se realizó un estudio epidemiológico transversal en la comunidad indígena de Hueyapan, perteneciente al municipio de Morelos, en 2017. Se calculó un tamaño de muestra de 338 viviendas; como criterios de inclusión se tomaron aquellas viviendas dónde la edad de residencia en Hueyapan fuera igual o mayor a cuatro años; se realizó un muestreo sistemático cada tres viviendas, además se analizaron bases de datos de INEGI y Secretaría de Salud de 2011 a 2015. RESULTADOS: en relación con la morbilidad, se encontró una tendencia ascendente en la tasa bruta. Dentro de las enfermedades más prevalentes se identificaron las enfermedades infecciosas como principales y se empezó a observar la aparición de enfermedades no transmisibles. En relación con la mortalidad, se observó una tendencia lineal en su tasa bruta. CONCLUSIONES: el perfil epidemiológico de Hueyapan coincide con un proceso de transición epidemiológica, donde existe una doble carga de enfermedad. Esto sugiere un reto para el área de la salud pública que debiera enfrentarse desde la creación de estrategias, programas y políticas de salud dirigidas a esta población desde un enfoque intercultural.

MBL2 single nucleotide polymorphism diversity among four ethnic groups as revealed by a bead-based liquid array profiling.

In the present work we established a rapid, cost-effective and high-throughput method for genotyping using a multiplexed microsphere-based suspension array platform - Luminex xMAP which enabled us to analyze 3 SNPs in the MBL2 gene promoter and 5' UTR, and 3 coding SNPs exon 1 haplotypes, associated with different levels of MBL2 expression. Using this system MBL2 diversity in four different ethnic groups, namely, Asian (Japanese), Caucasian, Hispanic and African-American-assessed. Results showed significant variability in terms of allele, genotype, and haplotype distribution. Characteristic MBL haplotype patterns were defined for each ethnic group. A prevalence of haplotypes coding functional proteins capable of complement activation and pathogen opsonization was observed. Regardless of the significant diversity of individual haplotypes, a high, almost similar (25-28%) proportion of haplotypes associated with MBL deficiency was found in the four ethic groups. The proportion of individuals homozygous for the haplotypes resulting in complete MBL2 deficiency was also significant (2-10%). Considering the role of MBL2 in innate immunity and as a clinically relevant marker, the genotyping approach developed and the knowledge of the genetic variation in different ethnic groups will be relevant to future medical genetic studies.

The association of infant feeding with parent-reported infections and hospitalisations in the West Australian Aboriginal Child Health Survey.

OBJECTIVE: To examine infant feeding associations with parent-reported infections and hospitalisations in Western Australian Aboriginal infants and children. METHOD: Families in Western Australia with children under 18 years of Aboriginal or Torres Strait Islander descent were included. A stratified multi-stage sample using an area-based sampling frame was compiled. Survey weights produced unbiased estimates for the population of families with Aboriginal children. Data were collected on demographic variables, maternal and infant characteristics and parent-reported recurring chest, ear and gastrointestinal infections. The data were linked to the Hospital Morbidity System to identify hospitalisations for infections for the same children. RESULTS: Twenty-seven per cent of Aboriginal children were breastfed for less than three months. Parent-reported recurring chest, ear and gastrointestinal infections were reported in 47% of the 0-3 age group. Hospitalisations due to upper respiratory and gastrointestinal infections were most common in the older children, but wheezing lower respiratory infections were most common in younger children. Breastfeeding for less than three months and birth weight less than 2,500 g were risk factors for parent-reported chest infections and hospitalisations for upper and wheezing lower respiratory infections (p<0.05). CONCLUSION: Rates of parent-reported chest infections and hospitalisations due to these infections continue to be high in Aboriginal infants and children. Because breastfeeding for less than three months and low birth weight are risk factors for these infections, interventions to reduce the prevalence of low birth weight and to increase breastfeeding rates should be primary health goals in Aboriginal communities for the benefits of Aboriginal infants and children.
