In western countries, negative illness perceptions are associated with poor health status and affect health outcomes in primary care populations. The aim of this study is to examine the relationship between illness perception and mental and physical health status in general hospital outpatients in China. This multicentre, cross-sectional study analysed a total of 281 consecutive patients from four general hospital outpatient departments of internal medicine and traditional Chinese medicine in Beijing and Kunming. The patients answered questionnaires concerning illness perception (Brief-IPQ), somatic symptom severity (Patient Health Questionnaire-15), illness behaviour (Scale for the Assessment of Illness Behaviour), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (Twelve-Item Short Form Health Survey). Negative illness perception, especially negative emotional reactions, perceived illness consequences, encumbering illness concerns, and strong illness identity were significantly associated with high emotional distress, impairing illness consequences, and a low mental and physical quality of life. Using a multiple linear regression model, five strongest correlates of negative illness perception were high anxiety, seeking diagnosis verification, low mental and physical quality of life and high somatic symptom severity. The variance explained by this model was 35%. Chinese general hospital outpatients showed associations between negative illness perceptions and poor mental and physical health status that were similar to those of primary care patients in western countries. The main difference was that no association with perceived illness control was found in Chinese patients. Chinese physicians should be sensitised to their patients' negative illness perceptions and should focus on helping patients cope with uncertainty and anxiety by providing an understandable illness model and increasing control beliefs.

Full Text Available There is a well-established link between marital status and mental health, but previous research has produced mixed results about the reasons for this relationship. Some studies propose that marriage provides protection from stressors and increases personal coping abilities (the causation perspective, whereas other studies argue that marriage markets “weed out” individuals predisposed to illness (the selection perspective. This article addresses the causation-versus-selection debate by examining the effect of marital status on duration of treatment for mental illness. The empirical analysis uses longitudinal data and GEE models to estimate group-level differences in duration of treatment. The results suggest that marriage does not appear to confer a health advantage in terms of duration of treatment. However, the study demonstrates that the never-married experience longer treatment time than the married, divorced, and widowed.

The study aims to provide a selective review of the literature pertaining to the hypothalamic-pituitary-adrenal (HPA) axis and immune abnormalities as informative biological indicators of vulnerability in bipolar disorder (BD). We summarize key findings relating to HPA axis and immunological abnormalities in bipolar patients and their high-risk offspring. Findings derive from a review of selected original papers published in the literature, and supplemented by papers identified through bibliography review. Neurobiological findings are discussed in the context of emergent BD in those at genetic risk and synthesized into a neurodevelopmental model of illness onset and progression. BD is associated with a number of genetic and possibly epigenetic abnormalities associated with neurotransmitter, hormonal and immunologically mediated neurobiological pathways. Data from clinical and high-risk studies implicate HPA axis and immune system abnormalities, which may represent inherited vulnerabilities important for the transition to illness onset. Post-mortem and clinical studies implicate intracellular signal transduction processes and disturbance in energy metabolism associated with established BD. Specifically, long-standing maladaptive alterations such as changes in neuronal systems may be mediated through changes in intracellular signalling pathways, oxidative stress, cellular energy metabolism and apoptosis associated with substantial burden of illness. Prospective longitudinal studies of endophenotypes and biomarkers such as HPA axis and immune abnormalities in high-risk offspring will be helpful to understand genetically mediated biological pathways associated with illness onset and progression. A clinical staging model describing emergent illness in those at genetic risk should facilitate this line of investigation. © 2011 Blackwell Publishing Asia Pty Ltd.

Childhood trauma and chronic illness in adulthood: mental health and socioeconomic status as explanatory factors and buffers.

Mock, Steven E; Arai, Susan M

2010-01-01

Experiences of traumatic events in childhood have been shown to have long-term consequences for health in adulthood. With data from the 2005 Canadian Community Health Survey we take a life course perspective of cumulative disadvantage and examine the potential role of mental health and socioeconomic status in adulthood as multiple mediators of the link between childhood trauma and chronic illness in adulthood. Mental health and socioeconomic status are also tested as buffers against the typically adverse consequences of childhood trauma. The results suggest mental health and socioeconomic status partially explain the association of childhood trauma with chronic illness in adulthood, with mental health showing a stronger effect. In addition, an analysis of the interactions suggested higher socioeconomic status is a potential protective factor for those with a history of trauma. Results also suggest cumulative disadvantage following trauma may lead to chronic illness and suggest the need for public health expenditures on resources such as counseling and income supports to prevent or reduce psychological harm and chronic illness resulting from traumatic events.

Canine parvoviral enteritis is a highly contagious viral illness caused by canine parvovirus-2 (CPV-2) which affects puppies of mainly 6-20 weeks of age. Vaccination is pivotal in preventing and controlling CPV-2 infection. Determination of antibody status is a critical determinant for successful vaccination. The hemagglutination inhibition (HI) test is 'gold standard' test for quantification of antibodies specific to CPV-2, although the execution of this test is not feasible under field conditions. The present study was undertaken to develop a point of care testing to determine immune status prior to CPV-2 vaccination or to detect seroconversion in immunized dogs by latex agglutination test (LAT) using recombinant antigen. Truncated portion of VP2 protein (tVP2) of CPV-2 was selected on the basis of antigenic indices, overexpressed the recombinant protein in E. coli system and was subsequently used in development of LAT. A total of 59 serum samples obtained from vaccinated (n = 54) and healthy unvaccinated (n = 5) dogs were tested. The positivity was observed in 85% (46/54) of these dogs with varying agglutination pattern. The overall sensitivity and specificity of latex agglutination test in comparison to HI test was recorded as 90% and 88% respectively with an agreement value of 90% (CI = 95%).

Nutritional support to maintain proper immune status during intense training.

Science.gov (United States)

Gleeson, Michael

2013-01-01

Prolonged exercise and heavy training are associated with depressed immune function which can increase the risk of picking up minor infections. To maintain robust immunity, athletes should eat a well-balanced diet sufficient to meet their energy, carbohydrate, protein, and micronutrient requirements. Dietary deficiencies of protein and specific micronutrients have long been associated with immune dysfunction and an adequate intake of iron, zinc, and vitamins A, D, E, B6 and B12 is particularly important in the maintenance of immune function. Consuming carbohydrate during prolonged strenuous exercise attenuates rises in stress hormones and appears to limit the degree of exercise-induced immune depression. Similar effects can be seen with daily ingestion of high-dose antioxidant vitamin supplements, though concerns have been expressed that excessive antioxidant intake may impair exercise training adaptations. It is safe to say with reasonable confidence that individual amino acids, colostrum, Echinacea, and zinc are unlikely to boost immunity or reduce infection risk in athletes. The ingestion of carbohydrate during exercise and daily consumption of probiotic and plant polyphenol (e.g. quercetin)-containing supplements or foodstuffs (e.g. non-alcoholic beer) currently offer the best chance of success. This approach is likely to be most effective for individuals who are particularly prone to illness. Copyright © 2013 Nestec Ltd., Vevey/S. Karger AG, Basel.

Full Text Available Serious mental illness can affect many aspects of an individual's ability to function in daily life. The aim of this investigation was to determine if the environmental and functional status of people with serious mental illness contribute to the high mortality risk observed in this patient group.We identified cases of schizophrenia, schizoaffective and bipolar disorder aged ≥ 15 years in a large secondary mental healthcare case register linked to national mortality tracing. We modelled the effect of activities of daily living (ADLs, living conditions, occupational and recreational activities and relationship factors (Health of the Nation Outcome Scale [HoNOS] subscales on all-cause mortality over a 4-year observation period (2007-10 using Cox regression.We identified 6,880 SMI cases (242 deaths in the observation period. ADL impairment was associated with an increased risk of all-cause mortality (adjusted HR 1.9; 95% CI 1.3-2.8; p = 0.001, p for trend across ADL categories = 0.001 after controlling for a broad range of covariates (including demographic factors, physical health, mental health symptoms and behaviours, socio-economic status and mental health service contact. No associations were found for the other three exposures. Stratification by age indicated that ADLs were most strongly associated with mortality in the youngest (15 to <35 years and oldest (≥ 55 years groups.Functional impairment in people with serious mental illness diagnoses is a marker of increased mortality risk, possibly in younger age groups as a marker of negative symptomatology.

To systematically review the association between maternal nutritional status in pregnancy and infant immune response to childhood vaccines. We reviewed literature on maternal nutrition during pregnancy, fetal immune system and vaccines and possible relationships. Thereafter, we undertook a systematic review of the literature of maternal nutritional status and infant vaccine response, extracted relevant information, assessed quality of the nine papers identified and present findings in a narrative format. From limited evidence of average quality, intrauterine nutrition deficiency could lead to functional deficit in the infant's immune function; child vaccine response may thus be negatively affected by maternal malnutrition. Response to childhood vaccination may be associated with fetal and early life environment; evaluation of programs should take this into account.

Full Text Available Abstract Background The natural history of cutaneous HPV is unclear and in particular, seroprevalence among individuals with different levels of immune function and ethnicity is unknown. As part of a study of cutaneous squamous cell carcinoma (SCC and HPV among organ transplant recipients (OTR from London, we investigated the seroprevalence and risk factors for 34 HPV types (detected using Luminex technology among 409 OTR patients without skin cancer (243 Caucasians and 166 non-Caucasians, 367 individuals with end stage renal failure on dialysis (222 Caucasians and 145 non-Caucasians and 152 immunocompetent (IC individuals without skin cancer (102 Caucasians and 50 non-Caucasians to compare the HPV seroprevalence in patients with differing immune status and ethnicity. In total, seroprevalence data from 928 individuals, all from London, was available. Results Overall, no difference between HPV seroprevalence by immune status was observed (P = 0.3 among Caucasian or among non-Caucasian individuals, with seroprevalence varying from 87% to 94% across different immune status and ethnic groups. Those individuals seropositive to multiple types of one genus were more likely to be seroreactive to multiple types of another genus, independent of immune status or ethnicity. Lower seroprevalence for gammaHPV 4, and to a lesser extent gammaHPV 48, were observed among OTR compared to IC and dialysis patients. Higher seroprevalence against antibodies to betaHPV 93 were detected more frequently in non-Caucasians than Caucasians whereas muHPV 1 and, to a lesser extent, gammaHPV 4 were found more frequently among Caucasians - these findings were independent of immune status. Within non-Caucasian subgroups, the seroprevalence of 8 HPV (alpha-mucosal HPV16 and 13, alpha-cutaneous HPV7 and 2, betaHPV8, 17, 23 and 38 was significantly (P Conclusion We did not observe major disturbance in antibody response between immunocompetent, dialysis and OTR individuals, but

Full Text Available Reduced immune functioning may have a negative impact on sleep and health, and vice versa. A survey among Dutch young adults (18–35 years old was administered to collect information on perception of reduced immunity and its relationship to sleep disorders, sleep duration, and quality. Sleep disorders were assessed with the SLEEP-50 questionnaire subscales of sleep apnea, insomnia, circadian rhythm disorder, and daily functioning. Dutch young adults (N = 574 completed the survey. Among them, subjects (N = 209; 36.4% reported perceived reduced immunity. Relative to those with a normal immune status, subjects reporting reduced immunity had significantly higher scores (p=0.0001 on sleep apnea (2.6 versus 3.6, insomnia (5.1 versus 6.8, and circadian rhythm disorder (2.1 versus 2.7. Subjects reporting reduced immunity also had significantly poorer daily functioning scores (5.4 versus 7.6, p=0.0001. No differences were observed in total sleep time, but those reporting reduced immunity had significantly poorer ratings of sleep quality (6.8 versus 7.2, p=0.0001. Our findings suggest that perceived reduced immunity is associated with sleep disturbances, impaired daily functioning, and a poorer sleep quality. Experimental studies including the assessment of immune biomarkers and objective measures of sleep (polysomnography should confirm the current observations.

2013-11-01

We examined how attitudes toward mental illness treatment and its course differ by serious psychological distress, mental illness treatment, chronic disease, and sociodemographic factors using representative state-based data. Using data from jurisdictions supporting the Behavioral Risk Factor Surveillance System's Mental Illness and Stigma Module (35 states, the District of Columbia, and Puerto Rico), we compared adjusted proportions of adults agreeing that "Treatment can help people with mental illness lead normal lives" (treatment effectiveness) and that "People are generally caring and sympathetic to people with mental illness" (supportive environment), by demographic characteristics, serious psychological distress, chronic disease status, and mental illness treatment. Attitudes regarding treatment effectiveness and a supportive environment for people with mental illness varied within and between groups. Most adults receiving mental illness treatment agreed that treatment is effective. Fewer adults with serious psychological distress than those without such distress agreed that treatment is effective. Fewer of those receiving treatment, those with psychological distress, and those with chronic disease perceived the environment as supportive. These data can be used to target interventions for population subgroups with less favorable attitudes and for surveillance.

The host response to septic shock is dynamic and complex. A sepsis-induced immunosuppression phase has recently been acknowledged and linked to bad outcomes and increased healthcare costs. Moreover, a marked suppression of the immune response has also been partially described in patients hospitalized in intensive care unit (ICU) for severe trauma or burns. It has been hypothesized that immune monitoring could enable identification of patients who might most benefit from novel, adjunctive immune-stimulating therapies. However, there is currently neither a clear definition for such injury-induced immunosuppression nor a stratification biomarker compatible with clinical constraints. We set up a prospective, longitudinal single-centre clinical study to determine the incidence, severity and persistency of innate and adaptive immune alterations in ICU patients. We optimized a workflow to describe and follow the immunoinflammatory status of 550 patients (septic shock, severe trauma/burn and major surgery) during the first 2 months after their initial injury. On each time point, two immune functional tests will be performed to determine whole-blood TNF-α production in response to ex vivo lipopolysaccharide stimulation and the T lymphocyte proliferation in response to phytohaemagglutinin. In addition, a complete immunophenotyping using flow cytometry including monocyte HLA-DR expression and lymphocyte subsets will be obtained. New markers (ie, levels of expression of host mRNA and viral reactivation) will be also evaluated. Reference intervals will be determined from a cohort of 150 age-matched healthy volunteers. This clinical study will provide, for the first time, data describing the immune status of severe ICU patients over time. Ethical approval has been obtained from the institutional review board (no 69HCL15_0379) and the French National Security agency for drugs and health-related products. Results will be disseminated through presentations at scientific meetings

Full Text Available Background: Palliative care is an approach that has been used to care for terminally ill patients. The current study was performed to assess the association between the status of patient dignity and quality of life (QOL in Iranian terminally ill patients with cancer. Materials and Methods: This descriptive correlational study was conducted on 210 end-stage cancer patients (102 men and 108 women who were referred to Seyed Al-Shohada Hospital, Isfahan, Iran, in 2015. To assess dignity status, we used the Patient Dignity Inventory. The Persian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire was used for QOL assessment. Results: There was a significant negative association between total dignity status and QOL scales. In addition, significant negative relationship was observed between dignity-related domains (loss of worth sense: r = −0.50, P< 0.001; anxiety and uncertainty: r = −0.51, P< 0.001; symptom distress: r = −0.62, P< 0.001; and loss of autonomy: r = −0.61, P< 0.001 and functional scale and some subscales of the QOL scale. In contrast, a significant positive relationship was found between dignity-related domains, and total symptom scale and fatigue. No significant relationship was observed between different items of dignity and global health status/QOL scale. Conclusions: High dignity status in terminally ill patients was associated with higher QOL in terms of functional intactness and lower symptom distress. Further studies are necessary to shed light to our findings.

Chronically ill patients such as people with type 2 diabetes develop perceptions of their illness, which will influence their coping behaviour. Perceptions are formed once a health threat has been recognised. Many people with type 2 diabetes suffer from multimorbidity, for example the combination with cardiovascular disease. Perceptions of one illness may influence perceptions of the other condition. The aim of the current study was to evaluate the effect of an intervention in type 2 diabetes patients with a first acute coronary event on change in illness perceptions and whether this mediates the intervention effect on health status. The current study is a secondary data analysis of a RCT. Two hundred one participants were randomised (1:1 ratio) to the intervention (n = 101, three home visits) or control group (n = 100). Outcome variables were diabetes and acute coronary event perceptions, assessed with the two separate Brief Illness Perceptions Questionnaires (BIPQs); and health status (Euroqol Visual Analog Scale (EQ-VAS)). The intervention effect was analysed using ANCOVA. Linear regression analyses were used to assess whether illness perceptions mediated the intervention effect on health status. A positive intervention effect was found on the BIPQ diabetes items coherence and treatment control (F = 8.19, p = 0.005; F = 14.01, p effect was found on the other BIPQ diabetes items consequence, personal control, identity, illness concern and emotional representation. Regarding the acute coronary event, a positive intervention effect on treatment control was found (F = 7.81, p = 0.006). No intervention effect was found on the other items of the acute coronary event BIPQ. Better diabetes coherence was associated with improved health status, whereas perceiving more treatment control was not. The mediating effect of the diabetes perception 'coherence' on health status was not significant. Targeting illness perceptions of people with

The North Carolina Immunization Registry (NCIR) has been available since 2004. We sought to measure its utilization among practices that provide primary care for children who are enrolled in a prospective influenza surveillance study. This study included children aged 0.5-17 years who presented with fever or acute respiratory symptoms to an emergency department or inpatient setting in Winston-Salem, North Carolina, from September 1, 2009, through May 19, 2010. Study team members verified influenza and pneumococcal immunization status by requesting records from each child's primary care practice and by independently reviewing the NCIR. We assessed agreement of nonregistry immunization medical records with NCIR data using the kappa statistic. Fifty-six practices confirmed the immunization status of 292 study-enrolled children. For most children (238/292, 82%), practices verified the child's immunizations by providing a copy of the NCIR record. For 54 children whose practices verified their immunizations by providing practice records alone, agreement with the NCIR by the kappa statistic was 0.6-0.7 for seasonal and monovalent H1N1 influenza vaccines and 0.8-0.9 for pneumococcal conjugate and polysaccharide vaccines. A total of 221 (98%) of 226 enrolled children younger than 6 years of age had 2 or more immunizations documented in the NCIR. NCIR usage may vary in other regions of North Carolina. More than 95% of children younger than 6 years of age had 2 or more immunizations documented in the NCIR; thus, the Centers for Disease Control and Prevention 2010 goal for immunization information systems was met in this population. We found substantial agreement between practice records and the NCIR for influenza and pneumococcal immunizations in children.

Role of medicinal plants on growth performance and immune status in fish.

Disease outbreaks increase proportionally with increases in intensive aquaculture. Natural products including medicinal plants have been known from thousands of years for treating some human diseases. It is well known that many active compounds are responsible for potential bio-activities. For that reason, there has been considerable interest in the use of medicinal plants in aquaculture with a view to providing safe and eco-friendly compounds for replacing antibiotics and chemical compounds as well as to enhance immune status and control fish diseases. This article describes a wide range of medicinal plants such as herbs, seeds, and spices with different forms such as crude, extracts, mixed and active compounds, used as immunostimulants and resulting in a marked enhancement in the immune system of fish to prevent and control microbial diseases. Moreover, different activity was recorded from plant parts like seeds, roots, flowers and leaves. The mode of action of medicinal plants was stimulation of the cellular and humoral immune response which was monitored through elevation in immune parameters. Various levels of immune stimulation have been shown by medicinal plants at different concentrations through injection or immersion or oral administration. However, it is critically important to determine the optimal dose to enhance the immune system of fish and avoid the risk of immunosuppression. Some medicinal plants have been used to replace the protein in fishmeal as a cheap source of protein and proved to be efficient in this respect. Medicinal plants can act as a growth promoter and immunomodulator at the same time. Further investigations should be carried out to examine the influence of those plants on fish health (including physiological and histological parameters) as a preliminary step for use in large scale in aquaculture. The current review describes the role of medicinal plants and their derivatives on innate and adaptive immune status as well as growth

To investigate the appreciation of written education about pain neurophysiology in patients with fibromyalgia (FM) and its effects on illness perceptions and perceived health status. A booklet explaining pain neurophysiology was sent to participants with FM. Appreciation was assessed with 10 questions addressing relevance (0-30) and reassurance (0-30). Illness perceptions, catastrophizing and health status were measured with the Revised Illness Perception Questionnaire (IPQ-R), the Pain Catastrophizing Scale (PCS) and the Fibromyalgia Impact Questionnaire (FIQ) at baseline (T0), after a 2-week control period (T1) and 6 weeks after the intervention (T2). Forty-one patients participated. Mean (SD) scores for relevance and reassurance were 21.6 (5.6) and 18.7 (5.7), respectively. Only illness coherence, emotional representations, pain and fatigue changed significantly between T0 and T2. Correlations between appreciation and changes in outcomes ranged between r=0.00 and r=0.34. Although a majority of subjects appreciated the written information, it did not have clinically relevant effects on illness perceptions, catastrophizing or impact of FM on daily life. Written education about pain neurophysiology is inadequate toward changing illness perceptions, catastrophizing or perceived health status of participants with FM; education should be incorporated into a broader multidisciplinary self-management program.

Innate and adaptive immune dysfunction, also referred to as cirrhosis-associated immune dysfunction syndrome, is a major component of cirrhosis, and plays a pivotal role in the pathogenesis of both the acute and chronic worsening of liver function. During the evolution of the disease, acute decompensation events associated with organ failure(s), so-called acute-on chronic liver failure, and chronic decompensation with progression of liver fibrosis and also development of disease specific complications, comprise distinct clinical entities with different immunopathology mechanisms. Enhanced bacterial translocation associated with systemic endotoxemia and increased occurrence of systemic bacterial infections have substantial impacts on both clinical situations. Acute and chronic exposure to bacteria and/or their products, however, can result in variable clinical consequences. The immune status of patients is not constant during the illness; consequently, alterations of the balance between pro- and anti-inflammatory processes result in very different dynamic courses. In this review we give a detailed overview of acquired immune dysfunction and its consequences for cirrhosis. We demonstrate the substantial influence of inherited innate immune dysfunction on acute and chronic inflammatory processes in cirrhosis caused by the pre-existing acquired immune dysfunction with limited compensatory mechanisms. Moreover, we highlight the current facts and future perspectives of how the assessment of immune dysfunction can assist clinicians in everyday practical decision-making when establishing treatment and care strategies for the patients with end-stage liver disease. Early and efficient recognition of inappropriate performance of the immune system is essential for overcoming complications, delaying progression and reducing mortality. PMID:24627592

Immigrants in Sweden have a higher rate of mental illness than the native Swedes. This study investigated to what extent the association between immigrant status and mental illness can be explained by a different distribution of known risk factors for impaired mental health between groups of immigrants and persons born in Sweden. The study is based on data from the Swedish PART-study, designed to identify risk factors for, and social consequences of, mental illness. The study population consists of a random sample of 10,423 Swedish citizens, whereof 1,109 were immigrants. The data was collected in the year 2000. The immigrants were divided into three groups based on country of origin (Scandinavians born outside Sweden, Europeans born outside Scandinavia, non-Europeans). The occurrence of mental illness among immigrants and native Swedes were compared not adjusting and adjusting for indicators of socioeconomic advantage/disadvantage (education, income, labour market position, etc). Mental illness was approximated with the WHO (ten) wellbeing index scale and depressive symptoms were measured with the major depression inventory scale (MDI). Immigrants' excess risk for low subjective wellbeing was completely accounted for by adjustment for known risk factors in all the immigrant groups. However, social-economic disadvantages could not account for the non-European immigrants' higher prevalence of depression (MDI), although the increased relative risk found in univariate analyses was substantially reduced. The findings in this study suggest that the association between immigrant status and mental illness appears above all to be an effect of a higher prevalence of social and economic disadvantage.

Pediatric HIV is growing at an alarming rate in developing countries. Due to their compromised immune status, children infected with HIV are prone to a number of opportunistic infections. Oral manifestations are the first signs of the disease in many of them. To assess the oral mucosal status of Indian children with HIV, based on their CD4 cell counts. Two hundred and twenty one HIV infected children aged 6-18 years from various HIV centers, were divided into three groups, based on their CD4 cell counts; Group 1: ≥500, Group 2: 201-499 and Group 3: ≤200 cells. The children in each group were further considered as 'prior to antiretroviral treatment (ART)' and 'on ART'. Oral mucosal examination was done based on presumptive criteria given by Ramos-Gomez for diagnosis of oro-facial lesions commonly associated with HIV infection in children. Data obtained was subjected to statistical analysis. Angular cheilitis and pseudomembranous candidiasis were the frequently seen oral lesions. Children with CD4 cell count ≥500 had significantly fewer oral lesions each. A high percentage of HIV-infected children were affected with oral mucosal lesions. There was a significant association between immune status and frequency of oral lesions. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Epidemiological evidence on the symptomatic profile, health status and illness behavior of people with subjective sensitivity to noise is still scarce. Also, it is unknown to what extent noise sensitivity co-occurs with other environmental sensitivities such as multi-chemical sensitivity and sensitivity to electromagnetic fields (EMF). A cross-sectional study performed in the Netherlands, combining self-administered questionnaires and electronic medical records of non-specific symptoms (NSS) registered by general practitioners (GP) allowed us to explore this further. The study sample consisted of 5806 participants, drawn from 21 general practices. Among participants, 722 (12.5%) responded “absolutely agree” to the statement “I am sensitive to noise”, comprising the high noise-sensitive (HNS) group. Compared to the rest of the sample, people in the HNS group reported significantly higher scores on number and duration of self-reported NSS, increased psychological distress, decreased sleep quality and general health, more negative symptom perceptions and higher prevalence of healthcare contacts, GP-registered NSS and prescriptions for antidepressants and benzodiazepines. These results remained robust after adjustment for demographic, residential and lifestyle characteristics, objectively measured nocturnal noise exposure from road-traffic and GP-registered morbidity. Co-occurrence rates with other environmental sensitivities varied between 9% and 50%. Individuals with self-declared sensitivity to noise are characterized by high prevalence of multiple NSS, poorer health status and increased illness behavior independently of noise exposure levels. Findings support the notion that different types of environmental sensitivities partly overlap. - Highlights: • People with self-reported noise sensitivity experience multiple non-specific symptoms. • They also report comparatively poorer health and increased illness behavior. • Co-occurrence with other

Critically ill patients develop severe stress, inflammation and a clinical state that may raise the utilization and metabolic replacement of pyridoxal-5'-phosphate decreasing their body reserves. This study was designed to assess the nutritional pyridoxal-5'-phosphate status in critical care patients with systemic inflammatory response syndrome, comparing them with a group of healthy people, and studying it's association with factors involved in the pyridoxine and other B vitamins metabolism, as the total antioxidant capacity and Hcy as cardiovascular risk biomarker. Prospective, multicentre, comparative, observational and analytic study. One hundred and three critically ill patients from different hospitals, and eighty four healthy subjects from Granada, Spain, all with informed consent. Data from daily nutritional assessment, ICU severity scores, clinical and nutritional parameters, antioxidant status and homocysteine levels was taken at admission and at the seventh day of the ICU stay. Thiamine, riboflavin, pyridoxine and folate status proved deficient in a large number of patients, being significantly lower in comparison with control group, and significantly decreased at 7th day of ICU stay. Higher homocysteine was observed in patients compared with control group (p < 0.05) where 31.5 and 26.8 percent of subjects presented hyperhomocysteinemia at initial and final of study, respectively. Antioxidant status was lower than control group in two periods analysed, and decreased at 7th day of ICU stay (p < 0.05) being associated with PLP deficiency. PLP deficiency was also correlated with hyperhomocysteinemia at two times measured (r. -0.73, p < 0.001; r. -0.69, p < 0.001, respectively), showing at day 7 an odds ratio of 6.62 in our multivariate model. Critically ill patients with SIRS show deficient B vitamin and low antioxidant statuses. Despite association found between PLP deficiency and low antioxidant status in critically ill patients, PLP deficiency

Full Text Available Background: Illness uncertainty is a source of a chronic and pervasive psychological stress for people living with human immunodeficiency virus (HIV/acquired immune deficiency syndrome (AIDS (PLWH, and largely affects their quality of life and the ability to cope with the disease. Based on the uncertainty in illness theory, the social support is one of the illness uncertainty antecedents, and influences the level of uncertainty perceived by patients. Aim: To examine uncertainty in PLWH and its correlation with social support in Iran. Materials and Methods: This cross-sectional correlational study was conducted with 80 PLWH presenting to AIDS Research Center, Tehran, Iran in 2013. The data collected using illness uncertainty and social support inventories were analyzed through Pearson′s correlation coefficient, Spearman′s correlation coefficient, and regression analysis. Results: The results showed a high level of illness uncertainty in PLWH and a negative significant correlation between perceived social support and illness uncertainty ( P = 0.01, r = -0.29. Conclusion: Uncertainty is a serious aspect of illness experience in Iranian PLWH. Providing adequate, structured information to patients as well as opportunities to discuss their concerns with other PLWH and receive emotional support from their health care providers may be worthwhile.

Stress Hyperglycemia, Insulin Treatment, and Innate Immune Cells

Full Text Available Hyperglycemia (HG and insulin resistance are the hallmarks of a profoundly altered metabolism in critical illness resulting from the release of cortisol, catecholamines, and cytokines, as well as glucagon and growth hormone. Recent studies have proposed a fundamental role of the immune system towards the development of insulin resistance in traumatic patients. A comprehensive review of published literatures on the effects of hyperglycemia and insulin on innate immunity in critical illness was conducted. This review explored the interaction between the innate immune system and trauma-induced hypermetabolism, while providing greater insight into unraveling the relationship between innate immune cells and hyperglycemia. Critical illness substantially disturbs glucose metabolism resulting in a state of hyperglycemia. Alterations in glucose and insulin regulation affect the immune function of cellular components comprising the innate immunity system. Innate immune system dysfunction via hyperglycemia is associated with a higher morbidity and mortality in critical illness. Along with others, we hypothesize that reduction in morbidity and mortality observed in patients receiving insulin treatment is partially due to its effect on the attenuation of the immune response. However, there still remains substantial controversy regarding moderate versus intensive insulin treatment. Future studies need to determine the integrated effects of HG and insulin on the regulation of innate immunity in order to provide more effective insulin treatment regimen for these patients.

The objective of this work was to compare characteristics of clinical condition and immune status of children with repeated respiratory diseases of different clinical and nosological forms after standard treatment and magnetotherapy. It was shown that magnetotherapy produces well-apparent immunocorrective effects in children with the affected upper and lower respiratory tracts including patients with bronchial obstruction syndrome. Positive changes of both cellular and humoral immunity characteristics were documented coupled to the improvement of serum cortisol levels. Results of the study give reason to recommend inclusion of magneotherapy in the combined treatment of children with repeated respiratory diseases.

Introduction: Beside positive effects on athlete's health, competitive sport can be linked with an increased risk of illness and injury. Because of high relative increases in training, additional physical and psychological strains, and an earlier specialization and professionalization, adolescent athletes needs an increased attention. Training can alter the immune system by inducing a temporary immunosuppression, finally developing infection symptoms. Previous studies identified Epstein Barr Virus (EBV) as potential indicator for the immune status. In addition to the identification of triggering risk factors for recurrent infections, the aim was to determine the interaction between training load, stress sense, immunological parameters, and clinical symptoms. Methods: A controlled, prospective, longitudinal study on young athletes (n = 274, mean age: 13.8 ± 1.5 yrs) was conducted between 2010 and 2014. Also 285 controls (students, who did not perform competitive sports, mean age: 14.5 ± 1.9 yrs) were recruited. Athletes were examined 3 times each year to determine the effects of stress factors (training load: training hours per week [Th/w]) on selected outcome parameters (clinical [susceptibility to infection, WURSS-21: 21-item Wisconsin Upper Respiratory Symptom Survey], immunological, psychological end points). As part of each visit, EBV serostatus and EBV-specific IgG tiers were studied longitudinally as potential immune markers. Results: Athletes (A) trained 14.9 ± 5.6 h weekly. Controls (C) showed no lower stress levels compared to athletes (p = 0.387). Twelve percent of athletes reported recurrent infections (C: 8.5%, p = 0.153), the presence of an upper respiratory tract infection (URTI) was achieved in 30.7%. EBV seroprevalence of athletes was 60.3% (C: 56.6%, p = 0.339). Mean EBV-specific IgG titer of athletes was 166 ± 115 U/ml (C: 137 ± 112 U/ml, p = 0.030). With increasing Th/w, higher stress levels were observed (p athletes showed no increased

The aim of this study was to investigate the effect of ill health and socioeconomic status on labor force exit due to unemployment, early retirement, disability pension, or becoming economically inactive. A secondary objective was to investigate the effect of ill health and socioeconomic status on return to work. A representative sample of the Dutch working population (N=15 152) was selected for a prospective study with ten years follow-up (93 917 person-years). Perceived health and individual and household characteristics were measured at baseline with the Permanent Quality of Life Survey (POLS) during 1999-2002. Statistics Netherlands ascertained employment status monthly from January 1999 to December 2008. Cox proportional hazards analyses were used to determine the factors that predicted labor force exit and return to work. Ill health increased the likelihood of labor force exit into unemployment [hazard ratio (HR) 1.89], disability pension (HR 6.39), and early retirement (HR 1.20), but was not a determinant of becoming economically inactive (HR 1.07). Workers with low socioeconomic status were, even after adjusting for ill health, more likely to leave the labor force due to unemployment, disability pension, and economic inactivity. Workers with ill health at baseline were less likely to return to work after unemployment (HR 0.75) or disability pension (HR 0.62). Socioeconomic status did not influence re-employment. Ill health is an important determinant for entering and maintaining paid employment. Workers with lower education were at increased risk for health-based selection out of paid employment. Policies to improve labor force participation, especially among low socioeconomic level workers, should protect workers with health problems against exclusion from the labor force.

The majority of HIV-infected children in sub-Saharan Africa have not been informed of their HIV status. Caregivers are reluctant to disclose HIV status to their children because of concern about the child's ability to understand, parental sense of guilt, and fear of social rejection and isolation. We hypothesized that the low prevalence of pediatric HIV disclosure in Ghana is due to lack of accurate HIV information and high HIV stigma among caregivers. This is a preliminary analysis of baseline data of an HIV pediatric disclosure intervention study in Ghana ("Sankofa"). "Sankofa" - is a two-arm randomized controlled clinical trial comparing disclosure intervention plus usual care (intervention arm) vs usual care (control arm) at Korle-Bu Teaching Hospital (KBTH; control arm) and Komfo-Anokye Teaching Hospital (KATH; intervention arm). We enrolled HIV-infected children, ages 7-18 years who do not know their HIV status, and their caregivers. Baseline data of caregivers included demographic characteristics; Brief HIV Knowledge Questionnaire (HIV-KQ-18); Brief Illness Perception Questionnaire; and HIV Stigma Scale. Simple and multivariable linear regression analyses were used to assess the relationship between caregiver characteristics and HIV knowledge, stigma, and illness perception. Two hundred and ninety-eight caregivers were enrolled between January 2013 and July 2014 at the two study sites; KBTH (n = 167) and KATH (n = 131). The median age of caregivers was 41 years; 80.5% of them were female and about 60% of caregivers were HIV-positive. Seventy-eight percent of caregivers were self-employed with low household income. In both unadjusted and adjusted analyses, HIV negative status and lower level of education were associated with poor scores on HIV-KQ. HIV positive status remained significant for higher level of stigma in the adjusted analyses. None of the caregiver's characteristics predicted caregiver's illness perception.

We studied the effects of enteral nutrition (EN) support initiated 1 week before surgery on postoperative nutritional status, immune function, and inflammatory response in gastric cancer patients. A total of 200 gastric cancer patients were randomly divided into two groups: EN starting 1 week before surgery (study group) and EN starting early after surgery (control group). The two groups received EN support, following different therapeutic schedules, until the 9th day after operation. In the patients, body weight, skinfold thickness, upper-arm circumference, white blood cell count, albumin, prealbumin, C-reactive protein, peripheral immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets, interleukin-6, and tumor necrosis factor-α were measured 10 days before and after surgery and on the first day after surgery. There was no statistically significant difference in the results of recovery time of passage of gas by anus, abdominal distension, stomachache, blood glucose, hepatic and renal functions, and electrolytes between the two groups of patients (P > 0. 05). Adverse reactions occurred to both groups at 1 and 2 days after operation. Such conditions was improved after the intravenous drip rate was adjusted. The albumin and prealbumin levels of the patients in both groups decreased at 1 day after operation (P gastric cancer patients can improve their postoperative nutritional status and immune function, can reduce inflammatory response, and is more conducive to the recovery of patients.

Sex-specific life history responses to nymphal diet quality and immune status in a field cricket.

Individual fitness is expected to benefit from earlier maturation at a larger body size and higher body condition. However, poor nutritional quality or high prevalence of disease make this difficult because individuals either cannot acquire sufficient resources or must divert resources to other fitness-related traits such as immunity. Under such conditions, individuals are expected to mature later at a smaller body size and in poorer body condition. Moreover, the juvenile environment can also produce longer-term effects on adult fitness by causing shifts in resource allocation strategies that could alter investment in immune function and affect adult lifespan. We manipulated diet quality and immune status of juvenile Texas field crickets, Gryllus texensis, to investigate how poor developmental conditions affect sex-specific investment in fitness-related traits. As predicted, a poor juvenile diet was related to smaller mass and body size at eclosion in both sexes. However, our results also reveal sexually dimorphic responses to different facets of the rearing environment: female life history decisions are affected more by diet quality, whereas males are affected more by immune status. We suggest that females respond to decreased nutritional income because this threatens their ability to achieve a large adult body size, whereas male fitness is more dependent on reaching adulthood and so they invest in immunity and survival to eclosion. © 2013 The Authors.

Full Text Available Objective: To analyze the association between influenza and pneumococcus vaccination and blood cholesterol and blood sugar measurement by Belgian elderly respondents (≥65 years and socio-demographic characteristics, risk factors, health status and socio-economic status (SES. Methods: A cross-sectional study based on 4,544 non-institutionalized elderly participants of the Belgian Health Interview Surveys 2004 and 2008. Multivariate logistic regression models were constructed to examine the independent effect of socio-demographic characteristics, risk factors, health status and SES on the four preventive services. Results: After adjustment for age, sex, region, survey year, living situation, risk factors (body mass index, smoking status, physical activity and health status (self-assessed health and longstanding illness lower educated elderly were significantly less likely to report a blood cholesterol and blood sugar measurement. For instance, elderly participants with no degree or only primary education were less likely to have had a cholesterol and blood sugar measurement compared with those with higher education. Pneumococcus vaccination was not related to educational level, but lower income groups were more likely to have had a pneumococcus immunization. Influenza vaccination was not significantly related to SES. Conclusion: The results highlight the need to promote cholesterol and blood sugar measurement for lower SE groups, and pneumococcus immunization for the entire elderly population. Influenza immunization seems to be equally spread among different SE groups.

Complex disorders like Gulf War illness (GWI) often defy diagnosis on the basis of a single biomarker and may only be distinguishable by considering the co-expression of multiple markers measured in response to a challenge. We demonstrate the practical application of such an approach using an example where blood was collected from 26 GWI, 13 healthy control subjects, and 9 unhealthy controls with chronic fatigue at three points during a graded exercise challenge. A 3-way multivariate projection model based on 12 markers of endocrine and immune function was constructed using a training set of n = 10 GWI and n = 11 healthy controls. These groups were separated almost completely on the basis of two co-expression patterns. In a separate test set these same features allowed for discrimination of new GWI subjects (n = 16) from unhealthy (n = 9) and healthy control subjects with a sensitivity of 70% and a specificity of 90%.

Full Text Available Vaccination of health care workers is an efficient way to reduce the risk of occupational infection and to prevent nosocomial transmission to vulnerable patients. Despite this, achieving high immunization rates among those professionals is a challenge. We assessed the immunization status of Residents in Pediatrics at the Federal University of São Paulo from June to December 2008. Their immunization records were checked and evaluated according to the Brazilian Immunization Schedule for health care workers. Considering all required vaccines, only 3.1% of the 64 Residents were up-to-date with their immunizations. Influenza was the vaccine with the lowest uptake (3.1% and measles and rubella were diseases with the highest evidence of immunity (62.5% each. Only 37.5% of Residents had received three hepatitis B vaccine doses with a subsequent serology confirming seroconversion. Moreover, the vast majority of Residents in Pediatrics who were not up-to-date were unaware of the fact. Both medical schools and Pediatric Residence programs should not only offer information but also check vaccination records in an effort to keep their healthcare workers´ vaccinations up-to-date.

The iron, folacin, vitamin B 12 , and zinc status of a group of economically and socially disadvantaged elderly persons in the Washington Metropolitan Area was evaluated. Factors related to deficiencies of these nutrients, the relationships between the status of these nutrients and cell-mediated immunity, and the relationships of iron, folacin and vitamin B 12 status to hemoglobin levels in the subjects were also examined. It was also determined whether there were any interactions among iron, folacin, vitamin B 12 and zinc status in their relationships to cell-mediated immunity. Socio-demographic and nutritional data on the subjects were obtained using a questionnaire. Dietary data were obtained using a dietary record. A fasting blood sample was drawn and the levels of ferritin, folate and vitamin B 12 , and the erythrocyte levels of folate were determined by radioassay. Plasma and hair zinc levels were determined by atomic absorption spectrophotometry. Cell-mediated immune response was determined by transformation of peripheral blood lymphocytes after stimulation by mitogens, and by allogenic lymphocytes in the mixed lymphocyte reaction

Henry-Christian, J.R.; Johnson, A.A.; Walters, C.S.; Greene, E.J.; Lindsey, A.A.

1986-01-01

The relationships of iron, folacin, vitamin B 12 and zinc status to cell-mediated immune response were investigated among 125 healthy, elderly persons (60-87 years of age). Plasma ferritin, plasma and red cell folate, and plasma vitamin B 12 levels were assayed immuno-radiometrically. Plasma and hair zinc levels were determined by atomic absorption spectroscopy. Immune response was determined by transformation of peripheral blood lymphocytes after stimulation with phytohemagglutinin (PHA) and concanavalin A (con A), and in mixed lymphocyte reaction. Deficiencies of iron, folacin vitamin B 12 and zinc were each associated (independently) with significantly lower lymphocyte responses to PHA and con A, and mixed lymphocyte reaction (P 12 or zinc. Further, they suggest that deficiencies of these nutrients may play a role in the depression of cell-mediated immunity with age, which in turn may lead to increased susceptibility to infectious diseases and cancer in the elderly

Insight and illness perception are two concepts of interest in the study of factors related to clinical outcome in patients with psychosis. Insight implies a risk of emotional distress for the patient. Illness perceptions, regardless of their accuracy, might be favorable or not to illness. Literature provides evidence of significant correlates of these factors with clinical outcome, but they are rarely included in a single study. 1) assessing insight and illness perception in a sample of Mexican patients who have experienced psychosis and, 2) analyzing how insight and illness perception relate to each other and how they relate to clinical status (i.e., positive, negative, and general psychopathology, depression, and anxiety). Sixty-one participants (55.7% females) were recruited from a public psychiatric hospital; insight and illness perceptions were assessed with the SUMD and the Brief-IPQ, respectively. Clinical status was assessed with the PANSS, CDS and BAI scales. Participants showed good insight, favorable illness perceptions for the cognitive and comprehension dimensions, but unfavorable for the emotional dimension. Clinical status of sample was characterized by mild symptoms. Poor insight related to positive symptoms and general psychopathology. Cognitive and emotional perceptions of illness were significantly associated to most clinical status parameters, whereas comprehension showed no significant results. The study not only replicates the significant association on insight and illness perception with clinical outcome, but shows how their patterns of interactions are different, reinforcing the idea that they are two distinct factors worthy of being habitually acknowledged in research and clinical practice.

Full Text Available Objectives: The aim of this study was to ascertain the correlation between various opportunistic infections and complications in human immunodeficiency virus (HIV-1-infected children and the immune status of these patients, evaluated by absolute cluster of differentiation 4 (CD4 count and CD4 percentage. Methods: This study was conducted from January 2009 to June 2010 at the Antiretroviral Treatment Centre of the Pt. B.D. Sharma Post Graduate Institute of Medical Sciences, a tertiary care hospital in Rohtak, Haryana, in northern India. A total of 20 HIV-1-infected children aged 4–57 months were studied. Demographic and baseline investigations were performed prior to the start of highly active antiretroviral therapy (HAART. A fixed-dose combination of HAART was given based on the patient’s weight. Baseline investigations were repeated after six months of HAART. Results: There was a significant increase in the patients’ haemoglobin, weight, height and CD4 count after six months of HAART. Significant improvements (P <0.05 were also noted in the patients’ immune status, graded according to the World Health Organization. Conclusion: This study observed that the severity and frequency of opportunistic complications in paediatric patients with HIV-1 increased with a fall in the CD4 count. The treatment of opportunistic infections, along with antiretroviral therapy, may lead to both clinical and immunological recovery as well as a decreased incidence of future opportunistic infections. The CD4 count may give treating physicians an initial idea about the immune status of each child and could also be used as a biological marker of HAART efficacy. Patient compliance must be ensured during HAART as this is a key factor in improving outcomes.

To evaluate the effect of Supportan, an enteral nutrition (EN) specific for tumor patients, on the nutritional status and immune function of late-staged gastric cancer patients undergoing chemotherapy. Sixty-six late-staged gastric cancer patients undergoing chemotherapy were randomly divided into EN group (n=33) and control group (n=33). During chemotherapy, the patients in EN group received Supportan and the patients in the control group received basic diet. On the 14th day before chemotherapy and after chemotherapy, nutritional status and cell immune indicators were evaluated. As for nutrition indicators, there were no significant differences in EN group before and after chemotherapy (P > 0.05). Total protein, hemoglobin, prealbumin and transferrin significantly decreased after chemotherapy compared with those before chemotherapy in the control group (Pnutrition in EN group were superior to that in the control group, however, the differences were not statistically significant. The incidences of nausea, vomiting and marrow inhibition in Supportan group was lower compared with those in the control group, but with no significant difference. Supportan can prevent malnutrition of the late-staged gastric cancer patients undergoing chemotherapy, and improve immune function and alleviate adverse effects of chemotherapy.

Full Text Available We investigated whether high-protein enteral nutrition with immune-modulating nutrients (IMHP enriched with β-glucan stimulates immune function in critically ill patients. In a randomized double-blind placebo-controlled study, 30 patients consumed one of three types of enteral nutrition: a control or IMHP with and without β-glucan. The IMHP with β-glucan group showed increases in natural killer (NK cell activities relative to the baseline, and greater increases were observed in NK cell activities relative to the control group after adjusting for age and gender. The IMHP groups with and without β-glucan had greater increases in serum prealbumin and decreases in high-sensitivity C-reactive protein (hs-CRP than the control group. The control group had a greater decrease in peripheral blood mononuclear cell (PBMC interleukin (IL-12 production than the IMHP with and without β-glucan groups. In all patients, the change (Δ in hs-CRP was correlated with Δ prealbumin and Δ PBMC IL-12, which were correlated with ΔNK cell activity and Δ prealbumin. This study showed beneficial effects of a combination treatment of β-glucan and IMHP on NK cell activity. Additionally, strong correlations among changes in NK cell activity, PBMC IL-12, and hs-CRP suggested that β-glucan could be an attractive candidate for stimulating protective immunity without enhanced inflammation (ClinicalTrials.gov: NCT02569203.

The aim of this study was to assess the effects of purified polymannuronate (PM) obtained from marine brown algae on the performance, antioxidant capacity, immune status, and cecal fermentation profile of broiler chickens. In a 42 d experiment, 540 (average BW 43.77±1.29 g) 1-d-old Arbor Acres male broilers were randomly divided into 5 treatments with 6 replicates of 18 chicks and fed a corn and soybean meal (SBM)-based diet supplemented with 0, 1, 2, 3, or 4 g/kg polymannuronate. Adding polymannuronate to the broiler chickens' diets resulted in a significantly increased ADG and improved feed conversion compared with the control treatment. From d 1 to 42, the ADG of broilers fed 1, 2, 3, or 4 g/kg of polymannuronate was increased by 2.58, 4.33, 4.20, and 3.47%, respectively. Furthermore, parameters related to immune status, antioxidant capacity, and composition of the cecal microflora in broiler chickens fed the polymannuronate-containing diets were altered compared with broiler chickens fed a diet without polymannuronate. Supplementation with polymannuronate significantly increased the concentrations of lactic acid and acetic acid in the cecum compared with the control group. The results indicate that polymannuronate has the potential to improve broiler chicken immune status, antioxidant capacity, and performance. © 2015 Poultry Science Association Inc.

Although different studies suggest that early enteral nutrition (EEN) has benefits in reducing infectious complications, there is no data that addresses whether delayed enteral nutrition (EN) is detrimental and if it may have effects on inflammatory responses and immune function. Forty-five critically ill patients with long fasting were randomly allocated in two groups according to the type of nutritional support. The first group included patients assuming a standard enteral nutrition (EN, n = 22) and the second group assuming a parenteral nutrition (PN, n = 23). The daily nutritional amount was 25 kcal (105 kJ)/kg for all patients. The inflammatory markers white blood cells (WBC), C-reactive protein (CRP), TNF-α, IL-1-β, IL-6, IL-4, IL- 10 and the immune T-lymphocyte sub-populations CD3+, CD4+, CD8+, and HLA-DR+ were evaluated at day 1, and after 2, 3 and 7 days. IL-4, IL-10, CD3+, CD4+, CD8+ and the CD4+/CD8+ ratio were not statistically different between the two groups. WBC and TNF-α in EN patients were higher than those in PN after 3 and 7 days (P fasting increased systemic inflammatory responses, whereas EN could modify immune function, therefore reducing hospital stay and costs.

Influenza causes significant morbidity and mortality, with considerable economic costs, including lost work productivity. Influenza vaccines may reduce the economic burden through primary prevention of influenza and reduction in illness severity. We examined illness severity and work productivity loss among working adults with medically attended acute respiratory illnesses and compared outcomes for subjects with and without laboratory-confirmed influenza and by influenza vaccination status among subjects with influenza during the 2012-2013 influenza season. Illnesses laboratory-confirmed as influenza (ie, cases) were subjectively assessed as more severe than illnesses not caused by influenza (ie, noncases) based on multiple measures, including current health status at study enrollment (≤7 days from illness onset) and current activity and sleep quality status relative to usual. Influenza cases reported missing 45% more work hours (20.5 vs 15.0; P productivity as impeded to a greater degree (6.0 vs 5.4; P productivity loss were noted for vaccinated subjects. Influenza illnesses were more severe and resulted in more missed work hours and productivity loss than illnesses not confirmed as influenza. Modest reductions in illness severity for vaccinated cases were observed. These findings highlight the burden of influenza illnesses and illustrate the importance of laboratory confirmation of influenza outcomes in evaluations of vaccine effectiveness. © The Author 2015.

Illness perceptions are cognitive frameworks that patients construct to make sense of their illness. Although the importance of these perceptions has been demonstrated in other chronic illness populations, few studies have focused on the illness perceptions of adults with congenital heart disease (CHD). This study examined (1) inter-country variation in illness perceptions, (2) associations between patient characteristics and illness perceptions, and (3) associations between illness perceptions and patient-reported outcomes. Our sample, taken from APPROACH-IS, consisted of 3258 adults with CHD from 15 different countries. Patients completed questionnaires on illness perceptions and patient-reported outcomes (i.e., quality of life, perceived health status, and symptoms of depression and anxiety). Patient characteristics included sex, age, marital status, educational level, employment status, CHD complexity, functional class, and ethnicity. Linear mixed models were applied. The inter-country variation in illness perceptions was generally small, yet patients from different countries differed in the extent to which they perceived their illness as chronic and worried about their illness. Patient characteristics that were linked to illness perceptions were sex, age, employment status, CHD complexity, functional class, and ethnicity. Higher scores on consequences, identity, and emotional representation, as well as lower scores on illness coherence and personal and treatment control, were associated with poorer patient-reported outcomes. This study emphasizes that, in order to gain a deeper understanding of patients' functioning, health-care providers should focus not only on objective indicators of illness severity such as the complexity of the heart defect, but also on subjective illness experiences.

To analyze the status of acute upper respiratory infection and influenza-like illness (ILI) among community residents in Jinan in 2015, and to make a understand of the patient's medical treatment behavior and influenza vaccination coverage status in 2014. Balloting method and convenient sampling method were used to launch a household survey. The residents who had been in Jinan for more than 3 months were selected, to investigate the residents' attack ratio of acute upper respiratory and influenza-like from Jan. 8 to Feb. 7, 2015. Totally, 1 300 persons from 410 families were involved in this survey which recovered 1 241 valid questionnaires with the efficiency of 95.5%. Based on the national age-urban demographic statistics in 2010, the attack rates of acute respiratory infections, influenza-like illness were estimated by the direct standardization method, and the influenza vaccination rates were also calculated in this study. χ(2)-test method was used to compare the different status of incidence and vaccination among residents with different features. The attack rate of acute upper respiratory infection and influenza-like illness in Jinan from January 8, 2015 to February 7, 2015 were 30.2% (375 cases), and 6.1% (76 cases), respectively, with a standardized rate of 29.1% and 5.4%. 5.3% (66 cases) of the residents have vaccinated with the influenza vaccine inoculation, with an adjusted rate of 3.8%. The attack rate difference of acute upper respiratory tract infections was statistically significant between each age group (χ(2)=17.121, P= 0.002). The 0-4 age group had a highest attack rate (45.4%) of acute respiratory infection, while the 15-24 age group got the lowest (26.5%). 38.9% (146 cases) of patients went for a treatment in hospital. Among them, 37.7% (55 cases) of them selected the county level hospitals for treatment, 37.7% (55 cases) selected the community level hospitals, and 24.6% (36 cases) selected the individual clinic.

The aim of this study was to determine the effect of the supplementation of an organic acid (citric acid), antibiotic growth promoter (avilamycin), and their combination for a period of 35 d on the growth, feed efficiency, carcass yield, tibia ash, and immune status of broilers. One hundred sixty 1-d-old broiler chicks (Hubbard Classic) were randomly distributed into 4 groups with 4 replicate cages having 10 birds in each. A corn-soybean-based diet was used as the basal diet (control). The basal diet was supplemented with an organic acid (citric acid, 0.5%), an antibiotic growth promoter (avilamycin, 0.001%), and their combination in other groups. The highest BW was attained in citric acid-fed chicks (1,318 g), which was significantly (P 0.05). Total feed intake was higher in citric acid-fed chicks compared with antibiotic-supplemented chicks. The addition of citric acid improved feed conversion efficiency (g of weight gain/ kg of feed intake) significantly (P ash percentage significantly (P ash, and immune status of broilers. Therefore, citric acid might be a useful additive instead of antibiotic growth promoters such as avilamycin, considering performance and health status of broilers.

The psychological status of caregivers of individuals with intellectual disability and psychiatric illness (PI) is important for effective management. The aim of this study was to examine the psychological status and its relationship with coping styles among these caregivers. Caregivers (N = 80) of individuals with intellectual disability (n = 40) and PI (n = 40) were administered a socio-demographic questionnaire, depression, anxiety and stress scale and COPE Inventory. Caregivers experienced depression, anxiety and stress symptoms. These symptoms were found to be significantly higher among caregivers of individuals with intellectual disability than those with PI. The most common coping style used was religious coping. Use of positive reinterpretation and growth was associated with lower levels of depression and stress symptoms. Caregivers' mental health plays an important role in the quality of care delivery and outcome. Use of appropriate coping styles can reduce the impact of these symptoms. © 2018 John Wiley & Sons Ltd.

Effects of preoperative one week enteral nutrition (EN) support on the postoperative nutritional status, immune function and inflammatory response of gastric cancer patients were investigated. 106 cases of gastric cancer patients were randomly divided into preoperative one week EN group (trial group) and early postoperative EN group (control group), which were continuously treated with EN support until the postoperative 9th day according to different treatment protocols. All the patients were checked for their body weight, skinfold thickness, upper arm circumference, white blood cell count (WBC), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), humoral immunity (IgA, IgG), T cell subsets (CD4, CD8 and CD4/CD8), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), etc. on the preoperative and the postoperative 1st and 10th day, respectively. PA and IgG levels of the experimental group were higher than those of the control group on the postoperative 10th day, whereas IL-6 level of the experimental group was lower than that of the control group. EN support for preoperative gastric cancer patients will improve the postoperative nutritional status and immune function, alleviate inflammatory response, and facilitate the recovery of patients.

We examine the determinants of patients' accounts of their own mental illness. In particular, we examine the factors that affect the likelihood of attributing one's own mental illness to controllable factors rather than non-controllable factors. Our quantitative measure of attributional control is derived from the coding of in-depth interviews with people with severe mental illness seeking treatment for the first time (N = 144). We find that those who occupy positions of social disadvantage (particularly African-American males and those who receive public assistance) are less likely to attribute their illness to controllable sources, suggesting that personal mental illness attributions are systematically related to a person's social location. We outline the significance of these findings for research on the psychological consequences of mental illness attributions.

Pediatric vaccinations have decreased the incidence and mortality from infectious diseases in children, but adolescents continue to be adversely affected by vaccine preventable disease. The present study was performed to determine the status of adolescents immunization and to investigate the effect of several socio-demographic factors on immunization. Using the cluster-sampling method, 817 adolescents were selected in 24 high schools (15,000 students) in central district of Erzurum (Turkey). Adolescents were categorized as completely vaccinated, incompletely vaccinated, unvaccinated or vaccination status unknown. Of the 817 adolescents, 6.9% were completely vaccinated, 24.4% were incompletely vaccinated and 64.1% were unvaccinated. The vaccination status of 4.6% of adolescents was unknown. A significantly correlation was seen between the number of siblings, the level of mother and father education, the level of parent's socio-economics status, health insurance and immunization status. Our findings indicated a small percentage of adolescents receive all of the recommended vaccine. In immunization programs in Turkey, priority should be given to increase adolescent immunization rate with a middle school and/or adolescents, vaccination.

Full Text Available Background Since the protection time by hepatitis B (HB vaccination is unclear, the strategy of immunization of junior students who previously received hepatitis vaccine is controversial. Objectives This study aimed to determine the status of immunity to hepatitis B in junior medical, nursing and obstetrics students with different hepatitis B virus (HBV vaccination patterns. Patients and Methods In an analytical cross-sectional study, 255 junior medical sciences students were tested for quantitative antibodies to hepatitis B surface antigen (anti-HBs. The proportion of protective immunity was compared in different vaccination patterns. Results Vaccination coverage rates were 74.1%. About half the participants didn’t show serological evidence of protective immunity; 68.9% had their last shot more than 10 years ago and 30.4% had a vaccination history of five years or less (P < 0.001. Geometric mean level of anti-HBs titer among students, who had received a primary series vaccine at birth, was significantly lower than students who had started vaccination at an older age (P < 0.001. Also, analysis of variance for geometric mean of anti-HBs titer showed significant differences between groups based on injection time from the last shot (P < 0.001 (post hoc comparisons resulted in a P value of < 0.001 for birth versus < 5 year group, and P < 0.001 for the 5 to 10 year group. The lowest rate of non-protective level belonged to participants with complete three doses and a booster additional shot (27.1%. The final model for independent predictors of anti-HBs positive status was made by a binary logistic regression analysis. The model included presence of a booster dose, injection time from last shot, and discipline of study. Conclusions This study shows lower anti-HBs among students who were vaccinated at infancy compared to those vaccinated at older childhood or adolescence. Also, subsequent measurement of anti-HBs level at the time of entrance to

2008-01-01

Full Text Available To clarify the role of CD8+ effector T cells for infectious complications, 92 recipients were classified according to the hierarchical clustering of preoperative CD8+CD45 isoforms: Group I was naive, Group II was effector memory, and Group III was effector (E T cell-dominant. The posttransplant infection rates progressively increased from 29% in Group I to 64.3% in Group III recipients. The posttransplant immune status was compared with the pretransplant status, based on the measure (% difference and its graphical form (scatter plot. In Groups I and II, both approaches showed a strong upward deviation from pretransplant status upon posttransplant infection, indicating an enhanced clearance of pathogens. In Group III, in contrast, both approaches showed a clear downward deviation from preoperative status, indicating deficient cytotoxicity. The % E difference and scatter plot can be used as a useful indicator of a posttransplant infectious complication.

Full Text Available A challenge facing immunization registries is developing measures of childhood immunization coverage that contain more information for setting policy than present vaccine series up-to-date (UTD rates. This study combined milestone analysis with provider encounter data to determine when children either do not receive indicated immunizations during medical encounters or fail to visit providers. Milestone analysis measures immunization status at key times between birth and age 2, when recommended immunizations first become late. The immunization status of a large population of children in the Oregon ALERT immunization registry and in the Oregon Health Plan was tracked across milestone ages. Findings indicate that the majority of children went back and forth with regard to having complete age-appropriate immunizations over time. We also found that immunization UTD rates when used alone are biased towards relating non-UTD status to a lack of visits to providers, instead of to provider visits on which recommended immunizations are not given.

Gulf War illnesses are autoimmune illnesses caused by reactive oxygen species which were caused by nerve agent prophylaxis.

Science.gov (United States)

Moss, J I

2012-08-01

Gulf War illnesses (GWI share many of the features of chronic fatigue syndrome (CFS) and both CFS and GWI may be the result of chronic immune system processes. The main suspected cause for GWI, the drug pyridostigmine bromide (PB), has been shown to cause neuronal damage from reactive oxygen species (ROS). ROS have been associated with IgM mediated autoimmune responses against ROS induced neoepitopes in depressed patients and this may also apply to CFS. It therefore follows that the drug used in the Gulf War caused ROS, the ROS modified native molecules, and that this trigged the autoimmune condition we refer to as Gulf War illnesses. Similar mechanisms may apply to other autoimmune illnesses. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available Immunization is a key element of public health, a pre-requisite to social and economic development, and a crucial element that enables every child to reach his or her full physical and intellectual potential. It is a prevention against various child killer diseases such as tuberculosis (Bacillus Calmette Gurine [BCG], tetanus, whooping cough, diphtheria, poliomyelitis, hepatitis B, yellow fever, and measles. The main objective of this study is to examine the relationships between household characteristics, social mobilization, and immunization status of under-5 children in Lagos metropolis, Nigeria. To achieve this objective, a non-experimental research design was adopted. The research method utilized in the design is cross-sectional survey. The sampled study location is Ojo local government area of Lagos State. A total of 265 respondents were randomly sampled for the survey using multistage random sampling technique. Generated data were analyzed using univariate, bivariate, and multivariate statistical techniques. The findings of the study reveal significant relationship between women’s level of education and full immunization of their children. Specifically, 38.9% of women without any formal education had fully immunized their children compared with 86.9% of women with secondary education. In addition, 90.9% of women who assessed themselves to be average on wealth assessment compared with 45.3% of the poor had fully immunized their children. On the basis of the study’s findings, there is a need for a holistic approach that will involve all social classes and communities on child immunization to have 100% immunization coverage and minimal child morbidity and mortality in all areas of the city.

The proportion of the United States population with chronic illness continues to rise. Understanding the determinants of quality of care-particularly social determinants-is critical to the provision of care in this population. To estimate the prevalence of housing and food insecurity among persons with common chronic conditions and to assess the independent effects of chronic illness and sociodemographic characteristics on (1) housing and food insecurity, and (2) health care access hardship and health status. Cross-sectional study. We used data from the 11 states and one territory that completed the social context module of the 2015 Behavioral Risk Factor Surveillance System (BRFSS). We estimated the prevalence of housing and food insecurity among patients with cancer, stroke, cardiovascular disease, and chronic lung disease. Logistic regression models were used to assess the independent effects of housing and food insecurity, chronic conditions, and demographics on health care access and health status. Among the chronically ill, 36.71% (95% CI: 35.54-37.88) experienced housing insecurity and 30.60% (95% CI: 29.49-31.71) experienced food insecurity. Cardiovascular and lung disease increased the likelihood of housing (OR 1.69, 95% CI: 1.07-2.66 and OR 1.71, 95% CI: 1.12-2.60, respectively) and food insecurity (OR 1.75, 95% CI: 1.12-2.73 and OR 1.78, 95% CI: 1.20-2.63, respectively). Housing and food insecurity significantly increased the risk of health care access hardship. Being insured or having an income level above 200% of the federal poverty level significantly reduced the likelihood of access hardship, while female gender significantly increased the likelihood. Chronic illness independently affects housing and food insecurity. In turn, food and housing anxiety leads to reduced access to care, likely due to cost concerns, and correlates with poorer health. A more complete understanding of the pathways by which chronic illness influences social determinants and

Compensation neurosis: financial reward for illness as nocebo.

Science.gov (United States)

Bellamy, R

1997-03-01

Results of medical treatment are notoriously poor in patients with pending litigation after personal injury or disability claims, and for those covered by workers' compensation programs. Although some instances of overt malingering are documented by surveillance videos, most exaggerated illness behavior in compensation situations takes place because of a combination of suggestion, somatization, and rationalization. A distorted sense of justice, victim status, and entitlement may further the exaggerated sick role. Adversarial administrative and legal systems challenging the claimant to prove repeatedly he or she is permanently ill harden the conviction of illness and the individual's defense of the claim. Unfortunately, after advocating for one's injury before a sometimes doubting public for the several years required to resolve such claims, care eliciting behavior too often remains permanent. Because any improvement in the claimant's health condition may result in denial of disability status in the future, the claimant is compelled to guard against getting well and is left with no honorable way to recover from illness. Financial reward for illness thus functions as a powerful nocebo, a nonspecific force creating and exacerbating illness. Solutions require recognition that judging disability and work incapacity in others is an unscientific process and that adversarial systems rewarding permanent illness or injury, particularly self reported pain, are often permanently harmful. The remainder of the solution must be political.

Full Text Available BACKGROUND: Hypothesizing that nutritional status, systemic inflammation and tumoral immune microenvironment play a role as determinants of lung cancer evolution, the purpose of this study was to assess their respective impact on long-term survival in resected non-small cell lung cancers (NSCLC. METHODS AND FINDINGS: Clinical, pathological and laboratory data of 303 patients surgically treated for NSCLC were retrospectively analyzed. C-reactive protein (CRP and prealbumin levels were recorded, and tumoral infiltration by CD8+ lymphocytes and mature dendritic cells was assessed. We observed that factors related to nutritional status, systemic inflammation and tumoral immune microenvironment were correlated; significant correlations were also found between these factors and other relevant clinical-pathological parameters. With respect to outcome, at univariate analysis we found statistically significant associations between survival and the following variables: Karnofsky index, American Society of Anesthesiologists (ASA class, CRP levels, prealbumin concentrations, extent of resection, pathologic stage, pT and pN parameters, presence of vascular emboli, and tumoral infiltration by either CD8+ lymphocytes or mature dendritic cells and, among adenocarcinoma type, tumor grade (all p285 mg/L prealbumin levels and high (>96/mm2 CD8+ cell count had a 5-year survival rate of 80% [60.9-91.1] as compared to 18% [7.9-35.6] in patients with an opposite pattern of values. When stages I-II were considered alone, the prognostic significance of these factors was even more pronounced. CONCLUSIONS: Our data show that nutrition, systemic inflammation and tumoral immune contexture are prognostic determinants that, taken together, may predict outcome.

We aimed to clarify associations between nutritional status and mortality in patients with acute renal failure. De-identified data were obtained from the Medical Information Mart for Intensive Care III database comprising more than 40,000 critical care patients treated at Beth Israel Deaconess Medical Centerbetween 2001 and 2012. Weight loss and body mass index criteria were used to define malnutrition. Data of 193 critically ill patients with acute renal failure were analyzed, including demographics, nutrition intervention, laboratory results, and disease severity. Main outcomes were in-hospital and 1-year mortality. The 1-year mortality was significantly higher in those with malnutrition than in those without malnutrition (50.0% vs 29.3%, p=0.010), but differences in in-hospital survival were not significant (p=0.255). Significant differences in mortality were found between those with malnutrition and without starting at the 52nd day after intensive care unit (ICU) discharge (p=0.036). No significant differences were found between men and women with malnutrition in in-hospital mortality (p=0.949) and 1-year mortality (p=0.051). Male patients requiring intervention with blood products/colloid supplements had greater risk of 1-year mortality, but without statistical significance. Nutritional status is a predictive factor for mortality among critically ill patients with acute renal failure, particularly 1-year mortality after ICU discharge. © American Federation for Medical Research (unless otherwise stated in the text of the article) 2018.

People with resilient traits are considered to have a better mental and physical health. However, there are limited data available assessing the relationship between resilient individuals and their perspective of their health and immune status. Therefore, this study was conducted to examine the relationship between mental resilience, perceived health, and perceived immune status. Methods: A total of 779 participants recruited at Utrecht University completed a questionnaire consisting of demographic characteristics, the brief resilience scale for the assessment of mental resilience, the immune function questionnaire (IFQ, and questions regarding their perceived health and immune status. Results: When correcting for gender, age, height, weight, smoker status, amount of cigarettes smoked per week, alcohol consumption status, amount of drinks consumed per week, drug use, and frequency of past year drug use, mental resilience was significantly correlated with perceived health (r=0.233, p=0.0001, perceived immune functioning (r=0.124, p=0.002, and IFQ score (r=−0.185, p=0.0001. Conclusion: A significant, albeit modest, relationship was found between mental resilience and perceived immune functioning and health.

Hyperglycemia, hypoglycemia, and increased glycemic variability have each been independently associated with increased risk of mortality in critically ill patients. The role of diabetic status on modulating the relation of these three domains of glycemic control with mortality remains uncertain. The purpose of this investigation was to determine how diabetic status affects the relation of hyperglycemia, hypoglycemia, and increased glycemic variability with the risk of mortality in critically ill patients. This is a retrospective analysis of prospectively collected data involving 44,964 patients admitted to 23 intensive care units (ICUs) from nine countries, between February 2001 and May 2012. We analyzed mean blood glucose concentration (BG), coefficient of variation (CV), and minimal BG and created multivariable models to analyze their independent association with mortality. Patients were stratified according to the diagnosis of diabetes. Among patients without diabetes, mean BG bands between 80 and 140 mg/dl were independently associated with decreased risk of mortality, and mean BG bands>or=140 mg/dl, with increased risk of mortality. Among patients with diabetes, mean BG from 80 to 110 mg/dl was associated with increased risk of mortality and mean BG from 110 to 180 mg/dl with decreased risk of mortality. An effect of center was noted on the relation between mean BG and mortality. Hypoglycemia, defined as minimum BGor=20%, was independently associated with increased risk of mortality only among patients without diabetes. Derangements of more than one domain of glycemic control had a cumulative association with mortality, especially for patients without diabetes. Although hyperglycemia, hypoglycemia, and increased glycemic variability is each independently associated with mortality in critically ill patients, diabetic status modulates these relations in clinically important ways. Our findings suggest that patients with diabetes may benefit from higher glucose

To determine if maternal health literacy influences early infant immunization status. Longitudinal prospective cohort study of 506 Medicaid-eligible mother-infant dyads. Immunization status at age 3 and 7 months was assessed in relation to maternal health literacy measured at birth using the Test of Functional Health Literacy in Adults (short version). Multivariable logistic regression quantified the effect of maternal health literacy on immunization status adjusting for the relevant covariates. The cohort consists of primarily African-American (87%), single (87%) mothers (mean age 23.4 years). Health literacy was inadequate or marginal among 24% of mothers. Immunizations were up-to-date among 73% of infants at age 3 months and 43% at 7 months. Maternal health literacy was not significantly associated with immunization status at either 3 or 7 months. In multivariable analysis, compared to infants who had delayed immunizations at 3 months, infants with up-to-date immunizations at 3 months were 11.3 times (95%CI 6.0-21.3) more likely to be up-to-date at 7 months. The only strong predictors of up-to-date immunization status at 3 months were maternal education (high school graduate or beyond) and attending a hospital-affiliated clinic. Though maternal health literacy is not associated with immunization status in this cohort, later immunization status is most strongly predicted by immunization status at 3 months. These results further support the importance of intervening from an early age to ensure that infants are fully protected against vaccine preventable diseases.

Trans-generational immune priming is the transmission of enhanced immunity to offspring following a parental immune challenge. Although within-generation increased investment into immunity demonstrates clear costs on reproductive investment in a number of taxa, the potential for immune priming to impact on offspring reproductive investment has not been thoroughly investigated. We explored the reproductive costs of immune priming in a field cricket, Teleogryllus oceanicus. To assess the relative importance of maternal and paternal immune status, mothers and fathers were immune-challenged with live bacteria or a control solution and assigned to one of four treatments in which one parent, neither or both parents were immune-challenged. Families of offspring were reared to adulthood under a food-restricted diet, and approximately 10 offspring in each family were assayed for two measures of immunocompetence. We additionally quantified offspring reproductive investment using sperm viability for males and ovary mass for females. We demonstrate that parental immune challenge has significant consequences for the immunocompetence and, in turn, reproductive investment of their male offspring. A complex interaction between maternal and paternal immune status increased the antibacterial immune response of male offspring. This increased immune response was associated with a reduction in son's sperm viability, implicating a trans-generational resource trade-off between investment into immunocompetence and reproduction. Our data also show that these costs are sexually dimorphic, as daughters did not demonstrate a similar increase in immunity, despite showing a reduction in ovary mass. © 2014 The Authors.

The Nordic countries have relatively equal employment participation between men and women, but some differences between countries exist in labour market participation. The aim was to examine the association between employment status and health among women and men in Denmark, Finland, Norway, and Sweden, and analyse whether this association is modified by marital status and parental status. The data come from nationally representative cross-sectional surveys carried out in Denmark (n = 2,209), Finland (n = 4,604), Norway (n = 1,844) and Sweden (n = 5,360) in 1994-95. Women and men aged 25-49 were included. Employment status was categorized into full-time employed, part-time employed, unemployed, and housewives among women and into employed and unemployed among men. Health was measured by perceived health and limiting longstanding illness. Logistic regression analysis was used, adjusting for age and education. Marital status and parental status were analysed as modifying factors. The non-employed were more likely to report perceived health as below good and limiting longstanding illness than the employed among both women and men. The association between employment status and perceived health remained unchanged when marital status and parental status were adjusted for among all men and Finnish women, but the association was slightly strengthened among Danish and Swedish women, with the housewives becoming more likely to report ill health than employed women. The association between employment status and limiting longstanding illness was slightly strengthened among women, and slightly weakened among Norwegian men when marital and parental status were adjusted for. Non-employment was associated with poorer health in all countries, although there are differences in the employment patterns between the countries. Among women marital status and parental status showed a modest or no influence on the association between employment status and health. Among men there was no

We aimed to show that the immune system is sensitive to the detrimental effects of inequality and social injustice, and splenic vulnerability to apoptosis may also increase. In order of better determination of immune responses to chronic social stress, we implemented food deprivation, food intake inequality, and unstable social status (a change of cage-mate every 3 days) for a period of 14 days in 60 male Balb/c mice. At the end of this stress period, nitric oxide (NO) production by peritoneal adherent cells and the serum concentration of corticosterone were measured. Moreover, the viability of peritoneal adherent cells and spleen lymphocytes was evaluated by MTT assay. The terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay was done to reveal the TUNEL-reactive apoptotic bodies in the spleen. Our results showed that food deprivation and inequality caused significant changes in the apoptosis of splenic cells in comparison with the control group (p social status did not cause a further increase in the viability of lymphocytes and peritoneal adherent cells, or NO production in animals that were food-deprived or experienced inequality. Serum concentration of corticosterone in all experimental groups, except for animals that experienced unstable social status only, significantly decreased versus the control group (p poverty and social inequality, but not unstable social status, affect immune responses and are likely involved in the induction of splenic apoptosis in mice. © 2017 S.

To assess individuals' perception of dental caries, in order to explain how illness representations might influence their coping with the disease. Cross-sectional questionnaire study. 520 consecutive patients (aged ≥18 years) of the General Dentistry Clinic at Universidad Cooperativa de Colombia, Pasto, Colombia who had experienced dental caries. Illness perception of dental caries was assessed using the Illness Perception Questionnaire Revised (IPQ-R). The most frequent self-reported symptoms associated with dental caries were "toothache" (56.2%), "tooth sensitivity" (53.8%) and "mild to sharp pain when eating or drinking" (51.2%). The dimensions of illness perception were related to socio-economic status (SES). Symptoms of "loose or separating teeth" and "pus in your tooth" were associated with dental caries by low SES participants, while "bleeding while brushing, flossing or eating hard food" and "mild to sharp pain when eating or drinking something sweet, hot or cold" were related more to higher SES. Perceptions of caries were related to socioeconomic status. Interventions to promote health literacy in order to improve the capacity to obtain, process and understand basic oral health information could increase an early detection of caries.

The aim of this study was to evaluate the effects of short-chain fructooligosaccharides (scFOS), xylooligosaccharides (XOS) and galactooligosaccharides (GOS) on immune and hepatic oxidative status, and gut morphology of white sea bream juveniles. Four diets were formulated: a control diet with fish meal (FM) and plant feedstuffs (PF) (30FM:70PF) and three test diets similar to the control but supplemented with 1% of scFOS, XOS or GOS. Dietary prebiotic incorporation did not affect total blood cell counts, hematocrit, hemoglobin, red blood indices or differential white blood cell counts. Fish fed GOS had lower ACH50 and nitric oxide than fish fed control diet. XOS enhanced immune status through the increase in alternative complement pathway (ACH50), lysozyme and total immunoglobulin. The higher activity of glucose 6-phosphate dehydrogenase in fish fed FOS compared to the other dietary groups was the only related antioxidant enzyme affected by prebiotics in the liver. GOS ameliorated the precocious adverse effects of PF based diet on gut histomorphology, as denoted by the lower incidence of histological alterations in fish fed GOS for 15 days. In conclusion, XOS and GOS at 1% might have potential to be used as prebiotics in white sea bream juveniles. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Dengue viruses (DENV are the most important mosquito transmitted viral pathogens infecting humans. DENV infection produces a spectrum of disease, most commonly causing a self-limiting flu-like illness known as dengue fever; yet with increased frequency, manifesting as life-threatening dengue hemorrhagic fever (DHF. Waning cross-protective immunity from any of the four dengue serotypes may enhance subsequent infection with another heterologous serotype to increase the probability of DHF. Decades of effort to develop dengue vaccines are reaching the finishing line with multiple candidates in clinical trials. Nevertheless, concerns remain that imbalanced immunity, due to the prolonged prime-boost schedules currently used in clinical trials, could leave some vaccinees temporarily unprotected or with increased susceptibility to enhanced disease. Here we develop a DENV serotype 1 (DENV-1 DNA vaccine with the immunodominant cross-reactive B cell epitopes associated with immune enhancement removed. We compare wild-type (WT with this cross-reactivity reduced (CRR vaccine and demonstrate that both vaccines are equally protective against lethal homologous DENV-1 challenge. Under conditions mimicking natural exposure prior to acquiring protective immunity, WT vaccinated mice enhanced a normally sub-lethal heterologous DENV-2 infection resulting in DHF-like disease and 95% mortality in AG129 mice. However, CRR vaccinated mice exhibited redirected serotype-specific and protective immunity, and significantly reduced morbidity and mortality not differing from naïve mice. Thus, we demonstrate in an in vivo DENV disease model, that non-protective vaccine-induced immunity can prime vaccinees for enhanced DHF-like disease and that CRR DNA immunization significantly reduces this potential vaccine safety concern. The sculpting of immune memory by the modified vaccine and resulting redirection of humoral immunity provide insight into DENV vaccine induced immune

Leptin is an adipocyte-derived hormone/cytokine that links nutritional status with neuroendocrine and immune functions. Initially described as an anti-obesity hormone, leptin has subsequently been shown to exert pleiotropic effects, being also able to influence haematopoiesis, thermogenesis, reproduction, angiogenesis, and more importantly immune homeostasis. As a cytokine, leptin can affect both innate and adaptive immunity, by inducing a pro-inflammatory response and thus playing a key role in the regulation of the pathogenesis of several autoimmune/inflammatory diseases. In this review, we discuss the most recent advances on the role of leptin as immune-modulator in mammals and we also provide an overview on its main functions in non-mammalian vertebrates.

Translational research in immune senescence: Assessing the relevance of current models

High, Kevin P.; Akbar, Arne N.; Nikolich-Zugich, Janko

2014-01-01

Advancing age is accompanied by profound changes in immune function; some are induced by the loss of critical niches that support development of naïve cells (e.g. thymic involution), others by the intrinsic physiology of long-lived cells attempting to maintain homeostasis, still others by extrinsic effects such as oxidative stress or long-term exposure to antigen due to persistent viral infections. Once compensatory mechanisms can no longer maintain a youthful phenotype the end result is the immune senescent milieu – one characterized by chronic, low grade, systemic inflammation and impaired responses to immune challenge, particularly when encountering new antigens. This state is associated with progression of chronic illnesses like atherosclerosis and dementia, and an increased risk of acute illness, disability and death in older adults. The complex interaction between immune senescence and chronic illness provides an ideal landscape for translational research with the potential to greatly affect human health. However, current animal models and even human investigative strategies for immune senescence have marked limitations, and the reductionist paradigm itself may be poorly suited to meet these challenges. A new paradigm, one that embraces complexity as a core feature of research in older adults is required to address the critical health issues facing the burgeoning senior population, the group that consumes the majority of healthcare resources. In this review, we outline the major advantages and limitations of current models and offer suggestions for how to move forward. PMID:22633440

Full Text Available Introduction: The employment status of mentally ill patients is a reflection of their productivity, control of illness besides providing therapeutic benefits and integration into mainstream society. Owing to the associated stigma, self-reporting of mental illness (SRMI often is rare. Census exercise of India in 2011 provides an insight of SRMI and employment status of such people. This study was undertaken to consider the role of gender, age group, and place on the employment status of SRMI. Methodology: Frequency of SRMI, age group, gender, and employment status was gathered from Indian 2011 census sources. Descriptive statistics and logistic regression were employed. P≤ 0.05 was taken as significant. Results: Majority (68.6% of the SRMI people resides in rural areas, in the economically productive age group of 15–59 years (75.88% and often males (57.51%. Of the SRMI as reported in the data, 78.62% were not employed while 2.4% of them were currently employed. The employability frequency distributions of SMRIs were statistically different in terms of area, age group, and gender with significance. Discussion: Although the mental illness data of 2011 census was rejected by mental health professionals citing discrepancy and underestimating of the prevalence of mental illness, it provides a robust estimate of the employability, self-reporting tendency of mental illness. The association of the factors provides a unique insight into SRMIs in India. Conclusion: Understanding the interplay of factors may yield robust estimates and clues for policy framers to formulate employment-related policies for employment opportunities for mentally ill patients.

Hogue, Michael D; Meador, Anna E

2016-03-01

Vaccines are among most cost-effective public health strategies. Despite effective vaccines for many bacterial and viral illnesses, tens of thousands of adults and hundreds of children die each year in the United States from vaccine-preventable diseases. Underutilization of vaccines requires rethinking the approach to incorporating vaccines into practice. Arguably, immunizations could be a part all health care encounters. Shared responsibility is paramount if deaths are to be reduced. This article reviews the available vaccines in the US market, as well as practice recommendations of the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices.

Aged Garlic Extract Modifies Human Immunity.

Science.gov (United States)

Percival, Susan S

2016-02-01

Garlic contains numerous compounds that have the potential to influence immunity. Immune cells, especially innate immune cells, are responsible for the inflammation necessary to kill pathogens. Two innate lymphocytes, γδ-T and natural killer (NK) cells, appear to be susceptible to diet modification. The purpose of this review was to summarize the influence of aged garlic extract (AGE) on the immune system. The author's laboratory is interested in AGE's effects on cell proliferation and activation and inflammation and to learn whether those changes might affect the occurrence and severity of colds and flu. Healthy human participants (n = 120), between 21 and 50 y of age, were recruited for a randomized, double-blind, placebo-controlled parallel-intervention study to consume 2.56 g AGE/d or placebo supplements for 90 d during the cold and flu season. Peripheral blood mononuclear cells were isolated before and after consumption, and γδ-T and NK cell function was assessed by flow cytometry. The effect on cold and flu symptoms was determined by using daily diary records of self-reported illnesses. After 45 d of AGE consumption, γδ-T and NK cells proliferated better and were more activated than cells from the placebo group. After 90 d, although the number of illnesses was not significantly different, the AGE group showed reduced cold and flu severity, with a reduction in the number of symptoms, the number of days participants functioned suboptimally, and the number of work/school days missed. These results suggest that AGE supplementation may enhance immune cell function and may be partly responsible for the reduced severity of colds and flu reported. The results also suggest that the immune system functions well with AGE supplementation, perhaps with less accompanying inflammation.

While contemporary heart failure management has led to some improvements in morbidity and mortality, patients continue to report poor health status (i.e., burdensome symptoms, impaired function, and poor quality of life). The Collaborative Care to Alleviate Symptoms and Adjust to Illness (CASA) trial is a NIH-funded, three-site, randomized clinical trial that examines the effect of the CASA intervention compared to usual care on the primary outcome of patient-reported health status at 6months in patients with heart failure and poor health status. The CASA intervention involves a nurse who works with patients to treat symptoms (e.g., shortness of breath, fatigue, pain) using disease-specific and palliative approaches, and a social worker who provides psychosocial care targeting depression and adjustment to illness. The intervention uses a collaborative care team model of health care delivery and is structured and primarily phone-based to enhance reproducibility and scalability. This article describes the rationale and design of the CASA trial, including several decision points: (1) how to design a patient-centered intervention to improve health status; (2) how to structure the intervention so that it is reproducible and scalable; and (3) how to systematically identify outpatients with heart failure most likely to need and benefit from the intervention. The results should provide valuable information to providers and health systems about the use of team care to manage symptoms and provide psychosocial care in chronic illness.

Vitamin D and neonatal immune function.

LENUS (Irish Health Repository)

Clancy, N

2013-05-01

Vitamin D deficiency is widespread in the neonatal and paediatric population of northern latitudes, particularly in children of African, Middle Eastern and Asian ethnicity. This is associated with diminished immune function and increases the risk of Th1 autoimmune diseases like type 1 diabetes. Epidermiological studies have also shown a link between vitamin D deficiency in children and a more severe course of illness with lower respiratory tract infection or Respiratory Syncitial Virus (RSV) bronchiolitis. The mechanism by which vitamin D enhances immunity is complex. It acts through the innate immune system by inducing antimicrobial peptides in epithelial cells, neutrophils and macrophages. The role of Vitamin D in neonatal and paediatric immunomodulation requires further study.

Microbial-immune cross-talk and regulation of the immune system.

We are all born germ-free. Following birth we enter into a lifelong relationship with microbes residing on our body's surfaces. The lower intestine is home to the highest microbial density in our body, which is also the highest microbial density known on Earth (up to 10(12) /g of luminal contents). With our indigenous microbial cells outnumbering our human cells by an order of magnitude our body is more microbial than human. Numerous immune adaptations confine these microbes within the mucosa, enabling most of us to live in peaceful homeostasis with our intestinal symbionts. Intestinal epithelial cells not only form a physical barrier between the bacteria-laden lumen and the rest of the body but also function as multi-tasking immune cells that sense the prevailing microbial (apical) and immune (basolateral) milieus, instruct the underlying immune cells, and adapt functionally. In the constant effort to ensure intestinal homeostasis, the immune system becomes educated to respond appropriately and in turn immune status can shape the microbial consortia. Here we review how the dynamic immune-microbial dialogue underlies maturation and regulation of the immune system and discuss recent findings on the impact of diet on both microbial ecology and immune function. © 2012 The Authors.

2013-07-01

Full Text Available This paper sought to synthesize what is currently known about mentally ill offenders in American jails and prisons based upon the most recent government and congressional reports and relevant literature review. The primary goal is to provide a detailed picture of the status of mentally ill offenders—including prevalence, basic demographic information, bio-psycho-social status, mental health, and family histories—and also to identify the problems, conditions, and obstacles faced while under the jurisdiction of the criminal justice system. Mentally ill offenders are constitutionally guaranteed basic mental health treatment. A review of the literature indicates that this constitutional guarantee is not being adequately fulfilled. Implications and suggestions for change are discussed.

Mass media depictions of people with mental illness have a strong influence on public attitudes, to the extent that changes in these depictions can reduce public stigmatization of people with such illness. Journalists' mental health may influence their depiction of those with mental illness, but little is known about this. To investigate mental illness among journalists in five key areas: (1) journalists' mental health status; (2) journalists' personal attitudes towards mental illness; (3) attitudes and support journalists expect or have experienced from colleagues when they have a mental health problem; (4) effect of journalism's professional culture on the course of mental illness; and (5) effect of journalism's professional culture on mass media depictions of people with mental illness. We performed a systematic screening of MEDLINE, PsycINFO, EMBASE, Web of Science and the Cochrane Library regarding the study aims. We identified 19, 12, seven and four studies for aims 1, 2, 3, and 4, respectively. No articles were found for aim 5. The prevalence of post-traumatic stress disorder (PTSD) among journalists is higher than that among the general population. Journalists have positive personal attitudes towards mental illness, but there are perceived workplace disincentives to disclose mental health problems.

This study aimed to determine the prevalence of motherhood among inpatient females at a large state psychiatric hospital in suburban New York, as well as develop an understanding of the characteristics and needs of this unique population. Data on motherhood status was gathered from October 2010 through April 2011 via medical records. Data on custody status, frequency of contacts with children, and effect of mental illness on parenting was assessed through patient surveys and focus groups. 38.5 % of female inpatients were found to be mothers, almost half of whom reported at least weekly contact with children despite their inpatient status. The majority of identified mothers reported having maintained custody of their minor children and expressed great pride at being primary caretakers for their children, yet also emphasized the challenging effects of stigma associated with mental illness and parenting. A significant proportion of women at this psychiatric hospital were found to be mothers. Although acknowledged by some clinicians at the individual level, motherhood appears to remain a forgotten role systemically. Determining motherhood status and recognizing the varied roles our patients have is one more way mental health providers can model and promote recovery-oriented care.

The aim of this study is to determine humoral immune status in Ukrainian children with clinical symptoms of irritable bowel syndrome 23 years after the Chernobyl disaster. The test population consisted of 95 participants: 75 rural patients aged 4-18, who lived in a contaminated area exposed to natural environmental radiation (falling under three groups) and 20 healthy urban participants from Kiev aged 5-15 as a control group. Internal radiation activity has been measured by gamma-ray spectrometry. B-lymphocytes population was analyzed with monoclonal antibody against antigen CD22(+). Serum immunoglobulins were evaluated by enzyme-linked immunosorbent assay (ELISA) method. p < 0.05 was considered significant. The percentage of CD22(+) in study groups is increased significantly in comparison to control group at p < 0.05. Reduced serum immunoglobulins levels have developed in the majority of the participants. Humoral immune status of study groups with clinical symptom of irritable bowel syndrome residing in a contaminated area has changed.

Antioxidant Vitamins and Trace Elements in Critical Illness.

Koekkoek, W A C Kristine; van Zanten, Arthur R H

2016-08-01

This comprehensive narrative review summarizes relevant antioxidant mechanisms, the antioxidant status, and effects of supplementation in critically ill patients for the most studied antioxidant vitamins A, C, and E and the enzyme cofactor trace elements selenium and zinc. Over the past 15 years, oxidative stress-mediated cell damage has been recognized to be fundamental to the pathophysiology of various critical illnesses such as acute respiratory distress syndrome, ischemia-reperfusion injury, and multiorgan dysfunction in sepsis. Related to these conditions, low plasma levels of antioxidant enzymes, vitamins, and trace elements have been frequently reported, and thus supplementation seems logical. However, low antioxidant plasma levels per se may not indicate low total body stores as critical illness may induce redistribution of antioxidants. Furthermore, low antioxidant levels may even be beneficial as pro-oxidants are essential in bacterial killing. The reviewed studies in critically ill patients show conflicting results. This may be due to different patient populations, study designs, timing, dosing regimens, and duration of the intervention and outcome measures evaluated. Therefore, at present, it remains unclear whether supplementation of antioxidant micronutrients has any clinical benefit in critically ill patients as some studies show clear benefits, whereas others demonstrate neutral outcomes and even harm. Combination therapy of antioxidants seems logical as they work in synergy and function as elements of the human antioxidant network. Further research should focus on defining the normal antioxidant status for critically ill patients and to study optimal supplement combinations either by nutrition enrichment or by enteral or parenteral pharmacological interventions. © 2016 American Society for Parenteral and Enteral Nutrition.

Full Text Available Introduction. Significant portion of patients with acute purulent-inflammatory diseases of the face and neck often has a pronounced secondary immunodeficiency. One manifestation of violation of protective functions in this group of patients are changes in the synthesis of interleukin blood. Knowledge about the of the immune changes in the early stages of the face and neck abscesses development can be used for choosing the right timely empirical therapy. However, the currently available data regarding immune abnormalities in this pathology are controversial. Perhaps this is due to the influence of geographical, environmental and socio-economic factors on the immune status of patients and the results of studies. Thus, to obtain an objective picture of the nature of changes in the body's defenses of patients with inflammatory processes of the face and neck, it is advisable to carry out the study of the state of immunity for each region separately, and that was the basis for this study Aim. to improve pyoinflammatory facial diseases diagnostics on the background of the cytokine status study. Materials and Methods. Serum cytokines (IL-1, TNFα, IL-6, IL-8, IL-4 concentration in 60 patients with maxillofacial phlegmon were determined with ELISA method. All patients were residents of Zaporozhye and the Zaporozhye area. Patients were divided into III groups: the 1st included 40 (66.7% patients with a checkered phlegmons space; 2nd group – 15 (25.0% patients with phlegmons of the more than one space; the 3rd group – 5 (8.3% patients with diffuse face and neck phlegmon, and with mediastinitis. The average age of patients was 37.0±7 years. 21 healthy subjects were included into control group. 5 ml of the peripheral blood was taken from the antecubital vein under aseptic conditions; and was placed in sterile tubes containing 25 IU of heparin per 1ml. Blood was centrifuged at 3000 rev./min for 10 minutes. Serum was dispensed at 0.3 ml. in plastic tubes

Changes in cell-mediated immunity in patients undergoing radiotherapy

1978-01-01

The cell-mediated immune status of 147 patients who received radiotherapy was evaluated using in vitro tests (PHA, E-rosette, and spontaneous blastogenesis) both before and 6 weeks after the end of radiation. All patients have verified malignancies, involving the bronchus in 29 cases, breast in 28, female genital system in 26, head and neck in 20 and bladder in 15. Patients suffering from bronchogenic carcinomas or malignancies of the head and neck showed a relative high degree of immune suppression. Our findings indicate a trend towards some improvement in PHA reactivity, as well as in the percentage of E-rosette-forming cells after treatment, which is more noticeable in patients with pelvic or breast tumors. A relationship seems to exist between the tumor load and the immune status, which reverts to a normal pattern when the former is extinguished. Moreover, patients with poor clinical response display a profoundly depressed level of immune status without any improvement after treatment

Full Text Available Background: Electrical Cardiometry allows measurement of fluid status using thoracic fluid content (TFC, cardiac output, cardiac index, systemic vascular resistance index which could be ideal noninvasive hemodynamic monitoring for patients undergoing hemodialysis (HD. Objectives: Investigating the relation between changes in TFC and amount of fluid removal during HD session and to monitor hemodynamic parameters to avoid episodes of hemodynamic compromise during HD session. Methods: Thirty critically ill patients on HD were enrolled. Clinical assessment of volume overload and hemodynamics (BP, MAP, CVP, monitored by Electrical Cardiometry ICON® before HD and all through sessions. Results: Out of studied patients males represented 46.7% (n = 14 with mean age 48 ± 16 years. There was positive correlation between UF volume and TFC (r = 0.410, P = 0.025. Out of the 30 pts studied 18 pts (60% were hemodynamically stable vs 12 pts (40% that had hypotension represented by non responders group and had lower TFC compared to the hemodynamically stable group (26.45 kohm−1 vs 37.8 kohm−1 with P value of 0.004 indicating that they were hypovolemic. Out of the 30 pts studied 18 pts (60% weren’t congested vs 12 pts (40% remained persistently congested after accomplishing HD session with significantly higher TFC when compared to those who got rid of congestion (43.14 ± 9.9 kohm−1 vs 25.44 ± 5.5 kohm−1 with P value of 0.0001 indicating that they were still hypervolemic. Using analysis of ROC curve TFC at 25.34 kohm−1 was a significant predictor of hypotension with P value of 0.002, AUC 83.4%, sensitivity 67% and specificity 100%. Also TFC cutoff value predicting persistent congestion was 37.02 kohm−1 with P value of 0.0001, AUC 95.8%, sensitivity 83% and specificity 100%. Conclusion: Electrical Cardiometry is an evolving noninvasive tool for adjusting fluid status of critically ill patient on RRT using thoracic fluid

Recovery of the immune system after exercise.

The notion that prolonged, intense exercise causes an "open window" of immunodepression during recovery after exercise is well accepted. Repeated exercise bouts or intensified training without sufficient recovery may increase the risk of illness. However, except for salivary IgA, clear and consistent markers of this immunodepression remain elusive. Exercise increases circulating neutrophil and monocyte counts and reduces circulating lymphocyte count during recovery. This lymphopenia results from preferential egress of lymphocyte subtypes with potent effector functions [e.g., natural killer (NK) cells, γδ T cells, and CD8 + T cells]. These lymphocytes most likely translocate to peripheral sites of potential antigen encounter (e.g., lungs and gut). This redeployment of effector lymphocytes is an integral part of the physiological stress response to exercise. Current knowledge about changes in immune function during recovery from exercise is derived from assessment at the cell population level of isolated cells ex vivo or in blood. This assessment can be biased by large changes in the distribution of immune cells between blood and peripheral tissues during and after exercise. Some evidence suggests that reduced immune cell function in vitro may coincide with changes in vivo and rates of illness after exercise, but more work is required to substantiate this notion. Among the various nutritional strategies and physical therapies that athletes use to recover from exercise, carbohydrate supplementation is the most effective for minimizing immune disturbances during exercise recovery. Sleep is an important aspect of recovery, but more research is needed to determine how sleep disruption influences the immune system of athletes. Copyright © 2017 the American Physiological Society.

Background Sleep is a predictor of infectious illness that may depend on one’s socioeconomic status (SES). Purpose This study aimed to investigate the moderating effects of objective and subjective SES on sleep-clinical cold risk link and test whether nasal inflammation serves as a plausible biological pathway. Methods This study combined data (n = 732) from three viral challenge studies. Measures of self-reported sleep and objective and subjective measures of SES were obtained. Participants were quarantined and administrated rhinovirus (RV) or influenza virus and monitored over 5 (RV) or 6 (influenza) days for the development of a cold. Symptom severity, including mucus production and nasal clearance time, and levels of nasal cytokines (interleukin (IL)-6 and IL-1β) were measured prior to administration and each day during the quarantined period. Results Subjective SES, but not objective SES, moderated associations between shorter sleep duration and increased likelihood of a clinical cold. Compared to ≥8-hour sleepers, ≤6-hour sleepers with low subjective SES were at increased risk for developing a cold (OR = 2.57, 95% CI 1.10–6.02). There was no association between sleep duration and colds in high subjective SES participants. Among infected individuals who reported low subjective SES, shorter sleep duration was associated with greater mucus production. There was no evidence that markers of nasal inflammation mediated the link between sleep duration and cold susceptibility among those reporting low subjective SES. Conclusion Subjective SES may reflect an important social factor for understanding vulnerability to and protection against infectious illness among short sleepers. PMID:27679462

A 9-week feeding trial was conducted to investigate the effects of graded dietary threonine (Thr) levels (0.58-2.58%) on the hematological parameters, immune response, antioxidant status and hepatopancreatic gene expression of antioxidant enzymes and antioxidant-immune-cytokine-related signaling molecules in juvenile blunt snout bream. For this purpose, 3 tanks were randomly arranged and assigned to each experimental diet. Fish were fed with their respective diet to apparent satiation 4 times daily. The results indicated that white blood cell, red blood cell and haemoglobin significantly responded to graded dietary Thr levels, while hematocrit didn't. Complement components (C3 and C4), total iron-binding capacity (TIBC), immunoglobulin M (IgM), superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) increased with increasing dietary Thr levels up to 1.58-2.08% and thereafter tended to decrease. Dietary Thr regulated the gene expressions of Cu/Zn-SOD, Mn-SOD and CAT, GPx1, glutathione S-transferase mu (GST), nuclear factor erythroid 2-related factor 2 (Nrf2), heat shock protein-70 (Hsp70), tumor necrosis factor-alpha (TNF-α), apolipoprotein A-I (ApoA1), glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and fructose-bisphosphate aldolase B (ALDOB); while the gene expression of peroxiredoxin II (PrxII) was not significantly modified by graded Thr levels. These genes are involved in different functions including antioxidant, immune, and defense responses, energy metabolism and protein synthesis. Therefore, this study could provide a new molecular tool for studies in fish immunonutrition and shed light on the regulatory mechanisms that dietary Thr improved the antioxidant and immune capacities of fish.

Health condition is one of the basic factors affecting satisfaction with life, and the level of illness acceptance. The purpose of the study was to analyse the level of illness acceptance, the level of satisfaction with life among malaria patients, and the level of trust placed in the physician and the nurse. The study employs the method of diagnostic survey based on standardised AIS and SWLS scales, as well as Anderson and Dedrick's PPTS and PNTS scales. The average AIS level was 12 points, while the average level of SwL at the SWLS scale was 16.5 points. The average level of trust in the physician and the nurse amounted to 50.6 points and 51.4 points, respectively. The correlation between the level of illness acceptance and self-evaluated satisfaction with life was statistically significant, with R = 0.56. The marital status influenced the level of illness acceptance with p satisfaction with life with p employment status affected the level of satisfaction with life with p satisfaction with life was low. The majority of respondents trusted their physician and nurse. There is a statistically significant correlation between the level of illness acceptance and the self-evaluated satisfaction with life. The marital status had a statistically significant effect on the acceptance of illness and the satisfaction with life. The individuals who had a job demonstrated higher levels of quality of life and illness acceptance.

Are immigrants and descendants with ill health more prone to unemployment? Evidence from 18 European countries.

Science.gov (United States)

Heggebø, Kristian

2017-08-01

Previous research has established that both ill health and minority status are associated with unemployment. Less is known, however, about the interplay between having ill health and being from minority background. The present study examines whether immigrants and descendants with ill health are particularly prone to unemployment during an economic downturn in Europe. The European Union Statistics on Income and Living Conditions (EU-SILC) cross-sectional data material is utilized, and linear probability models are estimated. The analysis is run for countries in which the two minority samples are acceptably large (N ≥ 100), resulting in 18 included European countries. The year 2011 is chosen because it is possible to identify both immigrants and descendants in EU-SILC due to a module on intergenerational transfer of disadvantages. The results indicate - as expected - that both ill health and minority status are independently related to higher unemployment likelihood. Immigrants and descendants with ill health, however, are not particularly likely to be unemployed. This finding is robust to a number of sensitivity tests, and the empirical pattern is very similar across the 18 included countries. Both minority status and ill health are associated with high unemployment probability in Europe. However, there does not seem to exist a 'double disadvantage' for immigrants and descendants with ill health, which is in line with a human capital perspective on how employers evaluate potential employees. Both a non-native-sounding name and bad health status are interpreted as a risk factor, but there is no reason to expect ill health to lower the productivity level more if the applicant is a descendant or immigrant.

The illness/non-illness model: hypnotherapy for physically ill patients.

Science.gov (United States)

Navon, Shaul

2014-07-01

This article proposes a focused, novel sub-set of the cognitive behavioral therapy approach to hypnotherapy for physically ill patients, based upon the illness/non-illness psychotherapeutic model for physically ill patients. The model is based on three logical rules used in differentiating illness from non-illness: duality, contradiction, and complementarity. The article discusses the use of hypnotic interventions to help physically ill and/or disabled patients distinguish between illness and non-illness in their psychotherapeutic themes and attitudes. Two case studies illustrate that patients in this special population group can be taught to learn the language of change and to use this language to overcome difficult situations. The model suggests a new clinical mode of treatment in which individuals who are physically ill and/or disabled are helped in coping with actual motifs and thoughts related to non-illness or non-disability.

McKay, Ryan; Buchmann, Andreas; Germann, Nicole; Yu, Shancong; Brugger, Peter

2014-12-01

At the centenary of research on anosognosia, the time seems ripe to supplement work in anosognosic patients with empirical studies on nosognosia in healthy participants. To this end, we adopted a signal detection framework to investigate the lateralized recognition of illness words--an operational measure of nosognosia--in healthy participants. As positively biased reports about one's current health status (anosognosia) and future health status (unrealistic optimism) have both been associated with deficient right hemispheric functioning, and conversely with undisturbed left hemispheric functioning, we hypothesised that more optimistic participants would adopt a more conservative response criterion, and/or display less sensitivity, when identifying illnesses in our nosognosia task; especially harmful illnesses presented to the left hemisphere via the right visual field. Thirty-two healthy right-handed men estimated their own relative risk of contracting a series of illnesses in the future, and then completed a novel computer task assessing their recognition of illness names presented to the left or right visual field. To check that effects were specific to the recognition of illness (rather than reflecting recognition of lexical items per se), we also administered a standard lateralized lexical decision task. Highly optimistic participants tended to be more conservative in detecting illnesses, especially harmful illnesses presented to the right visual field. Contrary to expectation, they were also more sensitive to illness names in this half-field. We suggest that, in evolutionary terms, unrealistic optimism may be an adaptive trait that combines a high perceptual sensitivity to threat with a high threshold for acknowledging its presence. The signal detection approach to nosognosia developed here may open up new avenues for the understanding of anosognosia in neurological patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

Role of ABO secretor status in mucosal innate immunity and H. pylori infection.

Full Text Available The fucosylated ABH antigens, which constitute the molecular basis for the ABO blood group system, are also expressed in salivary secretions and gastrointestinal epithelia in individuals of positive secretor status; however, the biological function of the ABO blood group system is unknown. Gastric mucosa biopsies of 41 Rhesus monkeys originating from Southern Asia were analyzed by immunohistochemistry. A majority of these animals were found to be of blood group B and weak-secretor phenotype (i.e., expressing both Lewis a and Lewis b antigens, which are also common in South Asian human populations. A selected group of ten monkeys was inoculated with Helicobacter pylori and studied for changes in gastric mucosal glycosylation during a 10-month period. We observed a loss in mucosal fucosylation and concurrent induction and time-dependent dynamics in gastric mucosal sialylation (carbohydrate marker of inflammation, which affect H. pylori adhesion targets and thus modulate host-bacterial interactions. Of particular relevance, gastric mucosal density of H. pylori, gastritis, and sialylation were all higher in secretor individuals compared to weak-secretors, the latter being apparently "protected." These results demonstrate that the secretor status plays an intrinsic role in resistance to H. pylori infection and suggest that the fucosylated secretor ABH antigens constitute interactive members of the human and primate mucosal innate immune system.

Immunity and inflammation in status epilepticus and its sequelae: possibilities for therapeutic application

Science.gov (United States)

Vezzani, Annamaria; Dingledine, Raymond; Rossetti, Andrea O

2016-01-01

Status epilepticus (SE) is a life-threatening neurological emergency often refractory to available treatment options. It is a very heterogeneous condition in terms of clinical presentation and causes, which besides genetic, vascular and other structural causes also include CNS or severe systemic infections, sudden withdrawal from benzodiazepines or anticonvulsants and rare autoimmune etiologies. Treatment of SE is essentially based on expert opinions and antiepileptic drug treatment per se seems to have no major impact on prognosis. There is, therefore, urgent need of novel therapies that rely upon a better understanding of the basic mechanisms underlying this clinical condition. Accumulating evidence in animal models highlights that inflammation ensuing in the brain during SE may play a determinant role in ongoing seizures and their long-term detrimental consequences, independent of an infection or auto-immune cause; this evidence encourages reconsideration of the treatment flow in SE patients.

of the secretory IgA and serum immunoglobulins, and lysozyme occurred in the content of oropharyngeal secretions. On the 7th day after the treatment the patients receiving Polioksidonium, had a significant increase in the phagocytic activity of neutrophils and biocide effect, and increase serum opsonizing properties. The autoserum increased both in the absorption capacity of neutrophils and their biocidal effect. Full restoration of the functional activity of phagocytic cells in these patients occurred by 30 days after treatment. To compare the group of patients we have studied that the properties of cells and serum opsonizing properties recovering very slowly and by 30 days were significantly different from the norm. On the 7th and 30th days after the end of the treatment the patients who received Polioksidonium, had an increase in antibody titer to infectious etiologic pathogens and IgG antibodies to CAD bacteria. The patients who did not receive Polioksidonium, such dynamic improvements in humoral immunity was observed. By 30th days after the treatment the patients in a comparison group the antibody titer to infectious etiologic pathogens and their affinity were not significantly changed compared to their values before treatment. The monitoring of patients during the year showed that the main group was not observed recurrence ChFh. They are much less likely than the comparison group was ill patients with acute respiratory infections, which are mild and not accompanied by complications. In the study group acute respiratory infections 2-3 times a year have been reported in 17 % of patients. Patients with ChFh comparison group relapses occurred in 40% of cases, of which 25% of patients - 2-3 times a year, 70% of patients 2-3 times a year suffered acute respiratory illness, which in 23,8% of cases complicated by acute bronchitis, 15% - by acute sinusitis. Conclusions: 1. Polioksidonium stimulates the increase of phagocytic and biocidal activity of white blood cells

Pigs living in intensive husbandry systems may experience both acute and chronic stress through standard management procedures and limitations in their physical and social environment, which may have implications for their immune status. Here, the effect of a new breeding method where pigs were selected on their heritable influence on their pen mates' growth, and environmental enrichment on the immune status of pigs was investigated. Hereto, 240 pigs with a relatively positive genetic effect on the growth of their pen mates (+SBV) and 240 pigs with a relatively negative genetic effect on the growth of their pen mates (-SBV) were housed in barren or straw-enriched pens from 4 to 23 weeks of age (n  =  80 pens in total). A blood sample was taken from the pigs before, three days after a 24 h regrouping test, and at week 22. In addition, effects of coping style, as assessed in a backtest, and gender were also investigated. Mainly, +SBV were found to have lower leukocyte, lymphocyte and haptoglobin concentrations than -SBV pigs. Enriched housed pigs had a lower neutrophil to lymphocyte (N:L) ratio and lower haptoglobin concentrations, but had higher antibody titers specific for Keyhole Limpet Hemocyanin (KLH) than barren housed pigs. No interactions were found between SBV class and housing. Furthermore, pigs with a proactive coping style had higher alternative complement activity and, in the enriched pens, higher antibody titers specific for KLH than pigs with a reactive coping style. Lastly, females tended to have lower leukocyte, but higher haptoglobin concentrations than castrated males. Overall, these results suggest that +SBV pigs and enriched housed pigs were less affected by stress than -SBV and barren housed pigs, respectively. Moreover, immune activation might be differently organized in individuals with different coping styles and to a lesser extent in individuals of opposite genders.

Dipika Neupane

Full Text Available Mental illness is stigmatized in most of the communities and people with such illness are often subjected to defame. Stigma impairs an individual's and their caregiver's physical, social and emotional wellbeing, and health-seeking behavior. Sufficient literature on how often the caregivers of people with mental illness from low and middle-income countries are stigmatized and how they perceive people with mental illness is unavailable. In this study, we examined caregivers' attitude towards people with mental illness and perceived stigma.We conducted face-to-face interviews with 170 caregivers in an outpatient clinic of a hospital in Nepal using a structured questionnaire. We calculated median and inter-quartile range of the attitude and perceived stigma scores. To assess the correlates, Kruskal Wallis H test and Mann Whitney U test were carried out.Overall median score for the domains: attitude (score range: 18-90 and perceived stigma (score range: 12-60 were 42 and 28 respectively, inter-quartile range being 8 each. Attitude score differed significantly by the sex of caregiver (p<0.05, educational status of caregiver (p<0.001, sex of patient (p<0.05 and type of mental illness (p<0.05. Perceived stigma score varied significantly by caregiver's sex (p<0.05, marital status (p<0.001, educational status (p<0.001, occupation (p<0.05, relation with the patient (p<0.005 and use of alternative treatment modalities (p<0.05.Sex of participant, educational status, sex of patient and type of mental illness were the correlates of attitude towards mental illness. Similarly, sex of participant, marital status, educational status, occupation, caregiver's relation with patient and use of alternative treatment modalities were correlates of perceived stigma. Findings of this study suggest that interventions targeting these high-risk populations might be beneficial to help build a positive attitude and overcome the perceived social stigma.

Nutritional Support of the Critically Ill Pediatric Patient: Foundations and Controversies

Full Text Available Critically ill children require nutritional support that will give them nutritional and non-nutritional support to successfully deal with their disease. In the past few years, we have been able to better understand the pathophysiology of critical illness, which has made possible the establishment of nutritional strategies resulting in an improved nutritional status, thus optimizing the pediatric intensive care unit (PICU stay and decreasing morbidity and mortality. Critical illness is associated with significant metabolic stress. It is crucial to understand the physiological response to stress to create nutritional recommendations for critically ill pediatric patients in the PICU.

Development of immune organs and functioning in humans and test animals: Implications for immune intervention studies.

A healthy immune status is mostly determined during early life stages and many immune-related diseases may find their origin in utero and the first years of life. Therefore, immune health optimization may be most effective during early life. This review is an inventory of immune organ maturation events in relation to developmental timeframes in minipig, rat, mouse and human. It is concluded that time windows of immune organ development in rodents can be translated to human, but minipig reflects the human timeframes better; however the lack of prenatal maternal-fetal immune interaction in minipig may cause less responsiveness to prenatal intervention. It is too early to conclude which immune parameters are most appropriate, because there are not enough comparative immune parameters. Filling these gaps will increase the predictability of results observed in experimental animals, and guide future intervention studies by assessing relevant parameters in the right corresponding developmental time frames.

'Intensive care unit survivorship' - a constructivist grounded theory of surviving critical illness.

To theorise intensive care unit survivorship after a critical illness based on longitudinal qualitative data. Increasingly, patients survive episodes of critical illness. However, the short- and long-term impact of critical illness includes physical, psychological, social and economic challenges long after hospital discharge. An appreciation is emerging that care needs to extend beyond critical illness to enable patients to reclaim their lives postdischarge with the term 'survivorship' being increasingly used in this context. What constitutes critical illness survivorship has, to date, not been theoretically explored. Longitudinal qualitative and constructivist grounded theory. Interviews (n = 46) with 17 participants were conducted at four time points: (1) before discharge from hospital, (2) four to six weeks postdischarge, (3) six months and (4) 12 months postdischarge across two adult intensive care unit setting. Individual face-to-face interviews. Data analysis followed the principles of Charmaz's constructivist grounded theory. 'Intensive care unit survivorship' emerged as the core category and was theorised using concepts such as status passages, liminality and temporality to understand the various transitions participants made postcritical illness. Intensive care unit survivorship describes the unscheduled status passage of falling critically ill and being taken to the threshold of life and the journey to a life postcritical illness. Surviving critical illness goes beyond recovery; surviving means 'moving on' to life postcritical illness. 'Moving on' incorporates a redefinition of self that incorporates any lingering intensive care unit legacies and being in control of one's life again. For healthcare professionals and policymakers, it is important to realise that recovery and transitioning through to survivorship happen within an individual's time frame, not a schedule imposed by the healthcare system. Currently, there are no care pathways or policies in

This experiment was conducted to investigate the effects of rumen-protected gamma-aminobutyric acid (GABA) on immune function and antioxidant status in heat-stressed dairy cows. Sixty Holstein dairy cows were randomly assigned to 1 of 4 treatments according to a completely randomized block design. The treatments consisted of 0 (control), 40, 80, or 120mg of GABA/kg DM from rumen-protected GABA. The trial lasted 10 weeks. The average temperature-humidity indices at 0700, 1400 and 2200h were 78.4, 80.2 and 78.7, respectively. Rectal temperatures decreased linearly at 0700, 1400, and 2200h with increasing GABA. As the GABA increased, the immunoglobulin (Ig) A and IgG contents and the proportions of CD4(+) and CD8(+) T lymphocytes increased linearly (Pheat-stressed dairy cows can improve their immune function and antioxidant activity.

Timing of the initiation of parenteral nutrition in critically ill children.

Jimenez, Lissette; Mehta, Nilesh M; Duggan, Christopher P

2017-05-01

To review the current literature evaluating clinical outcomes of early and delayed parenteral nutrition initiation among critically ill children. Nutritional management remains an important aspect of care among the critically ill, with enteral nutrition generally preferred. However, inability to advance enteral feeds to caloric goals and contraindications to enteral nutrition often leads to reliance on parenteral nutrition. The timing of parenteral nutrition initiation is varied among critically ill children, and derives from an assessment of nutritional status, energy requirements, and physiologic differences between adults and children, including higher nutrient needs and lower body reserves. A recent randomized control study among critically ill children suggests improved clinical outcomes with avoiding initiation of parenteral nutrition on day 1 of admission to the pediatric ICU. Although there is no consensus on the optimal timing of parenteral nutrition initiation among critically ill children, recent literature does not support the immediate initiation of parenteral nutrition on pediatric ICU admission. A common theme in the reviewed literature highlights the importance of accurate assessment of nutritional status and energy expenditure in deciding when to initiate parenteral nutrition. As with all medical interventions, the initiation of parenteral nutrition should be considered in light of the known benefits of judiciously provided nutritional support with the known risks of artificial, parenteral feeding.

Inflammatory cytokines in the brain: does the CNS shape immune responses?

Science.gov (United States)

Owens, T; Renno, T; Taupin, V; Krakowski, M

1994-12-01

Immune responses in the central nervous system (CNS) have traditionally been regarded as representing the intrusion of an unruly, ill-behaved mob of leukocytes into the well-ordered and organized domain of thought and reason. However, results accumulated over the past few years suggest that, far from being an immunologically privileged organ, T lymphocytes may be regular and frequent visitors to the CNS, for purposes of immune surveillance. Here, Trevor Owens and colleagues propose that the brain itself can regulate or shape immune responses therein. Furthermore, given that the immune cells may be subverted to autoimmunity, they suggest that the study of inflammatory autoimmune disease in the brain may shed light on the ability of the local environment to regulate immune responses.

Age related changes in T cell mediated immune response and effector memory to Respiratory Syncytial Virus (RSV in healthy subjects

Directory of Open Access Journals (Sweden)

Campoccia Giuseppe

2010-10-01

Full Text Available Abstract Respiratory syncytial virus (RSV is the major pathogen causing respiratory disease in young infants and it is an important cause of serious illness in the elderly since the infection provides limited immune protection against reinfection. In order to explain this phenomenon, we investigated whether healthy adults of different age (20-40; 41-60 and > 60 years, have differences in central and effector memory, RSV-specific CD8+ T cell memory immune response and regulatory T cell expression status. In the peripheral blood of these donors, we were unable to detect any age related difference in term of central (CD45RA-CCR7+ and effector (CD45RA-CCR7- memory T cell frequency. On the contrary, we found a significant increase in immunosuppressive regulatory (CD4+25+FoxP3+ T cells (Treg in the elderly. An immunocytofluorimetric RSV pentamer analysis performed on these donors' peripheral blood mononuclear cells (PBMCs, in vitro sensitized against RSV antigen, revealed a marked decline in long-lasting RSV specific CD8+ memory T cell precursors expressing interleukin 7 receptor α (IL-7Rα, in the elderly. This effect was paralleled by a progressive switch from a Th1 (IFN-γ and TNF-α to a Th2 (IL-10 functional phenotype. On the contrary, an increase in Treg was observed with aging. The finding of Treg over-expression status, a prominent Th2 response and an inefficient RSV-specific effector memory CD8+ T cell expansion in older donors could explain the poor protection against RSV reinfection and the increased risk to develop an RSV-related severe illness in this population. Our finding also lays the basis for new therapeutic perspectives that could limit or prevent severe RSV infection in elderly.

Behavioural conditioning of immune functions: how the central nervous system controls peripheral immune responses by evoking associative learning processes.

2008-01-01

During the last 30 years of psychoneuroimmunology research the intense bi-directional communication between the central nervous system (CNS) and the immune system has been demonstrated in studies on the interaction between the nervous-endocrine-immune systems. One of the most intriguing examples of such interaction is the capability of the CNS to associate an immune status with specific environmental stimuli. In this review, we systematically summarize experimental evidence demonstrating the behavioural conditioning of peripheral immune functions. In particular, we focus on the mechanisms underlying the behavioural conditioning process and provide a theoretical framework that indicates the potential feasibility of behaviourally conditioned immune changes in clinical situations.

To evaluate and compare the effects of Bacillus coagulans-fermented Ginkgo biloba (FG) and nonfermented Ginkgo biloba (NFG) on the immunity status of broiler chickens, 180 1-d-old female Arbor Acres chicks were divided into 3 groups and fed either a basal diet, a basal diet supplemented with 0.3% NFG, or a basal diet supplemented with 0.3% FG. Blood samples were taken on the seventh (before vaccination), 14th, 21st, 28th and 35th day for the assessment of serum IL-18 and interferon γ (IFN-γ) levels by ELISA. In addition, Newcastle disease antibody titer analysis was made via hemagglutination and hemagglutination inhibition test methods. On d 35, 6 chickens from each group were sacrificed and the thymus, liver, spleen, small intestine (jejunum segment), cecum, and bursa of Fabricius from each chicken were removed for analysis. RNA was isolated for defensin expression detection by real-time PCR (q-PCR). The results showed that serum IL-18 and IFN-γ levels decreased after treatment with NFG and FG compared with untreated control chickens. The ND antibody titers did not differ significantly between the 3 groups on the seventh, 14th, 21st and 28th day; however, on the 35th day, the ND antibody titers of the NFG and FG chickens were both significantly higher than those of control group chickens. Defensin RNA expression levels were inhibited by NFG; however, they were induced by FG. In conclusion, fermentation of Ginkgo biloba with Bacillus coagulans can promote the beneficial effect of Gingko biloba on the immunity status of broiler chickens.

Diet and host-microbial crosstalk in postnatal intestinal immune homeostasis.

Science.gov (United States)

Jain, Nitya; Walker, W Allan

2015-01-01

Neonates face unique challenges in the period following birth. The postnatal immune system is in the early stages of development and has a range of functional capabilities that are distinct from the mature adult immune system. Bidirectional immune-microbial interactions regulate the development of mucosal immunity and alter the composition of the microbiota, which contributes to overall host well-being. In the past few years, nutrition has been highlighted as a third element in this interaction that governs host health by modulating microbial composition and the function of the immune system. Dietary changes and imbalances can disturb the immune-microbiota homeostasis, which might alter susceptibility to several autoimmune and metabolic diseases. Major changes in cultural traditions, socioeconomic status and agriculture are affecting the nutritional status of humans worldwide, which is altering core intestinal microbial communities. This phenomenon is especially relevant to the neonatal and paediatric populations, in which the microbiota and immune system are extremely sensitive to dietary influences. In this Review, we discuss the current state of knowledge regarding early-life nutrition, its effects on the microbiota and the consequences of diet-induced perturbation of the structure of the microbial community on mucosal immunity and disease susceptibility.

Intestinal crosstalk: a new paradigm for understanding the gut as the "motor" of critical illness.

Clark, Jessica A; Coopersmith, Craig M

2007-10-01

For more than 20 years, the gut has been hypothesized to be the "motor" of multiple organ dysfunction syndrome. As critical care research has evolved, there have been multiple mechanisms by which the gastrointestinal tract has been proposed to drive systemic inflammation. Many of these disparate mechanisms have proved to be important in the origin and propagation of critical illness. However, this has led to an unusual situation where investigators describing the gut as a "motor" revving the systemic inflammatory response syndrome are frequently describing wholly different processes to support their claim (i.e., increased apoptosis, altered tight junctions, translocation, cytokine production, crosstalk with commensal bacteria, etc). The purpose of this review is to present a unifying theory as to how the gut drives critical illness. Although the gastrointestinal tract is frequently described simply as "the gut," it is actually made up of (1) an epithelium; (2) a diverse and robust immune arm, which contains most of the immune cells in the body; and (3) the commensal bacteria, which contain more cells than are present in the entire host organism. We propose that the intestinal epithelium, the intestinal immune system, and the intestine's endogenous bacteria all play vital roles driving multiple organ dysfunction syndrome, and the complex crosstalk between these three interrelated portions of the gastrointestinal tract is what cumulatively makes the gut a "motor" of critical illness.

Role of maternally derived immunity in fish.

Maternal immunity is of paramount importance for protection of young ones at early stage of life since the immune factors of an immunocompetent female are transferred transplacentally or through colostrum, milk or yolk to an immunologically naive neonate. Both innate and adaptive type of immunity are transferred of from mother to offspring in fishes. These factors include immunoglobulin (Ig)/antibody, complement factors, lysozymes, protease inhibitors like alpha macroglobulin, different types of lectins and serine proteases like molecules. Among different types of Ig viz. IgM, IgD, IgT/IgZ and IgM-IgZ chimera types, IgM is present in most of the teleostean fishes. In teleosts, IgM either as a reduced/breakdown product or monomeric form is usually transferred to the offsprings. The maternally derived IgM usually persists for a limited duration, exhausts within the completion of yolk absorption process, and completely disappears thereafter during larval stages. Maternal transfer of immunity which provides defense to embryo and larvae depends upon the health as well as the immune status of brood fish. The overall health status of brood fish can affect breeding performances, quality seed production and protection of offsprings. However, factors such as age, maturation, reproductive behaviour and nutrition (micro and macro-nutrients) may affect the immunity in brood fishes. Besides these, seasonal changes such as photoperiods, temperature, adverse environmental conditions, and stress conditions like handling, crowding, and water pollution/contamination can also affect the immunity of brood fishes. The maintenance of the brood stock immunity at high level during vitellogenesis and oogenesis, is utmost important for reducing mortalities at larval/post larval stages through maximum/optimum transfer of maternal immunity. Brood stock immunization prior to breeding as well as selective breeding among the disease resistant families might be the ideal criteria for producing

Spreading of multiple epidemics with cross immunization.

Pathogen-host relationships are the result of an ongoing coevolutionary race where the immune system of the host attempts to eliminate the pathogen, while the successful pathogen mutates to become invisible for the host's immune system. We here propose a minimal pathogen-host evolution model that takes into account cross immunization and allows for evolution of a spatially heterogeneous immune status of a population of hosts. With only the mutation rate as a determining parameter, the model allows us to produce an evolutionary tree of diseases which is highly branched, but hardly ever splits into separate long-lived trunks. Side branches remain short lived and seldom diverge to the extent of losing all cross immunizations.

The aim of this study was to assess sociodemographic factors and factors connected with treatment of mental illness and to decide whether they can influence the level of self-stigma. Sociodemographic characteristics (age, gender, family status, level of employment, level of education) and characteristics related to illness and treatment (diagnosis, length of treatment, adherence to treatment) were gathered in a group of patients in stable mental condition, without acute symptoms of mental illness. Self-stigma was measured using the Self-stigma of Mental Illness Scale - short form (SSMIS-SF). The sample included 197 patients: 99 patients in group 1 (G1) with psychosis and 98 in group 2 (G2) with anxious and affective disorders. The average age was 44.15 ± 12.91 years, the length of illness was 11.67 ± 9.21 years and 48% of patients were men. The total average SSMIS-SF score was 61.54 ± 23.34. We found no statistically significant difference in the total level of self-stigmatisation between these groups ( t(197) = 0.77; p = .441). The level of self-stigmatisation (total score of SSMIS-SF) in patients in G1 (psychosis) increased with the length of illness r(99) = .253; p = .011. Employment status seems to correlate with the level of self-stigmatisation ( F(3, 184) = 5.27; p = .002). Patients unemployed and on disability pension had higher levels of self-stigmatisation than patients working full-time. Patients who took medication regularly (full medical adherence) had lower scores of SSMIS-SF total scores in comparison with patients with lower compliance ( t(195) = 3.476; p = .001; Cohen's d = .25). According to our results, with regard to the factors that were followed, self-stigmatisation correlates with the presence of employment (social inclusion), duration of illness in patients with psychosis and treatment adherence. We did not find a statistically significant influence of age, gender, marital status or clinical diagnosis on the level of self-stigma.

To assess the immunization status of children aged 12-23 months and its determinants in Aden, Yemen. This cross-sectional survey was conducted between March and July 2007 during which time mothers of 680 children from 37 randomly selected clusters in Aden, were interviewed. Information on socio-demographic profiles and children's immunization status was obtained. Immunization coverage of all officially provided vaccines was assessed. Analysis of association between immunization coverage and the socio-demographic characteristics were tested using logistic regression analysis with the immunization status as the dependent variable. We found that 83.1% had complete, 10.4% had partial, and 6.5% were never immunized. The immunization card retention rate was 84.9%. The immunization coverage was 92.9% for Bacillus-Calmette-Guerin, 89.6% for Oral Polio Vaccine-3, 86.6% for Diphtheria, Pertusis and Tetanus-3 and Hepatitis-B vaccination, and 89.1% for measles. Multivariate analysis showed that children with an immunization card (odds ratio [OR]=14.71; 95% confidence interval [CI]: 8.50-25.44) were more likely to have complete immunization, while children with older aged mothers (OR=0.41; 95% CI: 0.22-0.77) were more likely to have complete immunization. Despite the high immunization coverage, 16.9% of children did not have complete immunization, and this rate was lower among children of older mothers, and those who retained their immunization cards. Raising awareness of immunization and increasing access to health services must be strengthened (Author).

Late effects of radiation on immune system; a review

International Nuclear Information System (INIS)

Sado, T.

1979-01-01

Lymphocytes are divided into 2 major classes: T and B lymphocytes (or cells). T cells are responsible for cell-mediated immune response, and B cells for humoral immune response or antibody formation. The possible immunological complications that might develop as the late manifestation of radiation effects include: lymphoid neoplasms, immune complex diseases, auto-aggressive immune reactions, and other degenerative diseases of immunological nature. The development of lymphoid neoplasma following the exposure to radiation was extensively studied with mice. Radiation-induced immunological compications would not contribute significantly to the life-shortening of exposed individuals. The extensive health survey of adult A-bomb survivors revealed little evidence of immunological complications such as rheumatoid arthritis, kidney diseases, paraproteinemia, etc. The young healthy adults who had received thymic irradiation during infancy for the treatment of enlarged thymus manifested higher incidence of illness with abnormal immunological features. Immune complex diseases, particularly the inter-capillary glomerulosclerosis of kidneys, develop as a result of earlier exposure to high dose of radiation. (Yamashita, S.)

Hinduism, marriage and mental illness.

For Hindus, marriage is a sacrosanct union. It is also an important social institution. Marriages in India are between two families, rather two individuals, arranged marriages and dowry are customary. The society as well as the Indian legislation attempt to protect marriage. Indian society is predominantly patriarchal. There are stringent gender roles, with women having a passive role and husband an active dominating role. Marriage and motherhood are the primary status roles for women. When afflicted mental illness married women are discriminated against married men. In the setting of mental illness many of the social values take their ugly forms in the form of domestic violence, dowry harassment, abuse of dowry law, dowry death, separation, and divorce. Societal norms are powerful and often override the legislative provisions in real life situations.

Defining the neurotoxin derived illness chronic ciguatera using markers of chronic systemic inflammatory disturbances: a case/control study.

2010-01-01

Ciguatoxins are extremely potent neurotoxins, produced by tropical marine dinoflagellates, that persistently enter into our food web. Over 100,000 people annually experience acute ciguatera poisoning from consuming toxic fish. Roughly 5% of these victims will develop chronic ciguatera (CC), a widespread, multisymptom, multisystem, chronic illness that can last tens of years. CC is marked by disproportionate disability and non-specific refractory symptoms such as fatigue, cognitive deficits and pain, and is suggestive of other illnesses. Its unknown pathophysiology makes both diagnosis and treatment difficult. We wanted to compare objective parameters of visual contrast sensitivity testing, measures of innate immune response and genetic markers in cases to controls to assess the potential for the presence of persistent inflammatory parameters that are demonstrated in other biotoxin associated illnesses at a single specialty clinic. Using 59 CC cases and 59 controls we present in retrospective review, in all cases, abnormalities in immune responses paralleling the chronic systemic inflammatory response syndrome seen in several other chronic diseases. This study defines a preliminary case definition using medical history, total symptoms, visual contrast sensitivity, HLA DR genotype analysis, reduction of regulatory neuropeptides VIP and MSH, and multiple measures of inflammatory immune response, especially C4a and TGFβ1, thereby providing a basis for identification and targeted therapy. CC provides a model for chronic human illness associated with initiation of inflammatory responses by biologically produced neurotoxins. Copyright © 2010 Elsevier Inc. All rights reserved.

Full Text Available Background: Fifty percent to 70% of the burden of childhood diarrhea and respiratory infections is attributable to undernutrition. It is compounded by food restriction during illness due to false beliefs, leading to a vicious cycle of malnutrition and infection. In the long run, it decreases the child′s productivity, which is an obstacle to sustainable socioeconomic development. Objectives: To assess the dietary practices during different illnesses, to study the role of education, culture and religion in feeding an ill child and to create awareness against detrimental practices. Materials and Methods: A cross-sectional study was undertaken among 126 caregivers of ill children using an open-ended pretested questionnaire. Statistical package for social sciences software was used for data analysis. Simple proportions, percentages and Chi-square were used. Results: Caregivers believed that a child must be fed less during illness. Educational status did not play a role in maintaining beliefs, but elders and religion did. Doctors too were responsible for unwanted dietary restrictions. Media did not have an impact in spreading nutrition messages. Decreased breast feeds, initiating bottle feeds, feeding diluted milk and reducing complementary feeds during illness was widely practiced. Calorie intake during illness was very less and statistically significant. Firmly rooted beliefs about "hot" and "cold" foods lead to restriction of food available at home. Conclusions: Healthy feeding practices were few, and inappropriate ones predominant. Dietary education was overlooked. While planning community-based nutrition programs, firmly rooted beliefs should be kept in mind. Involving the elderly caregivers and mothers actively along with the health workers is the need of the hour.

Innate Immunity Evasion by Enteroviruses: Insights into Virus-Host Interaction

Directory of Open Access Journals (Sweden)

Xiaobo Lei

2016-01-01

Full Text Available Enterovirus genus includes multiple important human pathogens, such as poliovirus, coxsackievirus, enterovirus (EV A71, EV-D68 and rhinovirus. Infection with EVs can cause numerous clinical conditions including poliomyelitis, meningitis and encephalitis, hand-foot-and-mouth disease, acute flaccid paralysis, diarrhea, myocarditis and respiratory illness. EVs, which are positive-sense single-stranded RNA viruses, trigger activation of the host antiviral innate immune responses through pathogen recognition receptors such as retinoic acid-inducible gene (RIG-I-likeand Toll-like receptors. In turn, EVs have developed sophisticated strategies to evade host antiviral responses. In this review, we discuss the interplay between the host innate immune responses and EV infection, with a primary focus on host immune detection and protection against EV infection and viral strategies to evade these antiviral immune responses.

Fluid balance disorders are a relevant risk factor for morbidity and mortality in critically ill patients. Volume assessment in the intensive care unit (ICU) is thus of great importance, but there are currently few methods to obtain an accurate and timely assessment of hydration status. Our aim was to evaluate the hydration status of ICU patients via bioelectric impedance vector analysis (BIVA) and to investigate the relationship between hydration and mortality. We evaluated 280 BIVA measurements of 64 patients performed daily in the 5 days following their ICU admission. The observation period ranged from a minimum of 72 h up to a maximum of 120 h. We observed the evolution of the hydration status during the ICU stay in this population, and analyzed the relationship between mean and maximum hydration reached and mortality--both in the ICU and at 60 days--using logistic regression. A state of overhydration was observed in the majority of patients (70%) on admission, which persisted during the ICU stay. Patients who required continuous renal replacement therapy (CRRT) were more likely to be overhydrated starting from the 2nd day of observation. Logistic regression showed a strong and significant correlation between mean/maximum hydration reached and mortality, both independently and correcting for severity of prognosis. Fluid overload measured by BIVA is a frequent condition in critically ill patients--whether or not they undergo CRRT--and a significant predictor of mortality. Hence, hydration status should be considered as an additional prognosticator in the clinical management of the critically ill patient. (i) On the day of ICU admittance, patients showed a marked tendency to overhydration (>70% of total). This tendency was more pronounced in patients on CRRT. (ii) Hyperhydration persisted during the ICU stay. Patients who underwent CRRT showed significantly higher hyperhydration from the 2nd day of hospitalization. (iii) Nonsurvivors showed worse hyperhydration

Immune regulation by microbiome metabolites.

Kim, Chang H

2018-03-22

Commensal microbes and the host immune system have been co-evolved for mutual regulation. Microbes regulate the host immune system, in part, by producing metabolites. A mounting body of evidence indicates that diverse microbial metabolites profoundly regulate the immune system via host receptors and other target molecules. Immune cells express metabolite-specific receptors such as P2X 7 , GPR41, GPR43, GPR109A, aryl hydrocarbon receptor precursor (AhR), pregnane X receptor (PXR), farnesoid X receptor (FXR), TGR5 and other molecular targets. Microbial metabolites and their receptors form an extensive array of signals to respond to changes in nutrition, health and immunological status. As a consequence, microbial metabolite signals contribute to nutrient harvest from diet, and regulate host metabolism and the immune system. Importantly, microbial metabolites bidirectionally function to promote both tolerance and immunity to effectively fight infection without developing inflammatory diseases. In pathogenic conditions, adverse effects of microbial metabolites have been observed as well. Key immune-regulatory functions of the metabolites, generated from carbohydrates, proteins and bile acids, are reviewed in this article. © 2018 John Wiley & Sons Ltd.

Probiotics in critically ill children [version 1; referees: 2 approved

Full Text Available Gut microflora contribute greatly to immune and nutritive functions and act as a physical barrier against pathogenic organisms across the gut mucosa. Critical illness disrupts the balance between host and gut microflora, facilitating colonization, overgrowth, and translocation of pathogens and microbial products across intestinal mucosal barrier and causing systemic inflammatory response syndrome and sepsis. Commonly used probiotics, which have been developed from organisms that form gut microbiota, singly or in combination, can restore gut microflora and offer the benefits similar to those offered by normal gut flora, namely immune enhancement, improved barrier function of the gastrointestinal tract (GIT, and prevention of bacterial translocation. Enteral supplementation of probiotic strains containing either Lactobacillus alone or in combination with Bifidobacterium reduced the incidence and severity of necrotizing enterocolitis and all-cause mortality in preterm infants. Orally administered Lactobacillus casei subspecies rhamnosus, Lactobacillus reuteri, and Lactobacillus rhamnosus were effective in the prevention of late-onset sepsis and GIT colonization by Candida in preterm very low birth weight infants. In critically ill children, probiotics are effective in the prevention and treatment of antibiotic-associated diarrhea. Oral administration of a mix of probiotics for 1 week to children on broad-spectrum antibiotics in a pediatric intensive care unit decreased GIT colonization by Candida, led to a 50% reduction in candiduria, and showed a trend toward decreased incidence of candidemia. However, routine use of probiotics cannot be supported on the basis of current scientific evidence. Safety of probiotics is also a concern; rarely, probiotics may cause bacteremia, fungemia, and sepsis in immunocompromised critically ill children. More studies are needed to answer questions on the effectiveness of a mix versus single-strain probiotics

to study the relationship between the expression of serum human leucocyte antigen-G5 (HLA-G5)/soluble CD30 (sCD30) and the function of renal graft in kidney transplant recipients and investigate the immune status of recipients with combined HLA-G5 and sCD30. from January 2002 to November 2008, a total of 66 kidney transplant recipients in our centre were selected as subjects and divided into three groups: stable function of renal graft (n = 38), acute rejection (n = 15) and chronic rejection (n = 13). The expressions of serum HLA-G5 and sCD30 were detected. There were two different immune conditions with acute/chronic allograft rejection and normal renal graft in kidney transplant recipients as evaluated by combined HLA-G5 and sCD30. The sensitivity, specificity and critical value of the method were analyzed by the curve of receiver operating characteristic. the levels of HLA-G5 and sCD30 were significantly correlated with serum creatinine (r = -0.493, 0.691, both P transplantation, the sensitivity was 78.6% and the specificity 85.7% when HLA-G5 critical value 82 microg/L and sCD30 critical value 12.2 microg/L. After one year post-transplantation: the sensitivity was 92.3% and the specificity 84.6% when HLA-G5 critical value 141 microg/L and sCD30 critical value 10.3 microg/L. the immune state of recipients are evaluated by combine HLA-G5 and sCD30 which may be a simple and valid method.

Among children investigated for maltreatment, those with parents experiencing mental illness or substance abuse are more likely to be placed out-of-home; however, little is known about why these children are at greater risk. Using a sample of 2488 Structured Decision Making ® assessments administered in San Francisco county from 2011 to 2015, we identified a profile of safety threats that accounts for why workers are more likely to determine children of parents with mental illness and/or substance abuse unsafe in the home. Eight percent of assessments in our sample involved parents with current mental illness only and 10% had comorbid substance abuse. The odds of an unsafe determination more than doubled among parents with mental illness (OR = 2.52, p mental illness on safety determination: caretaking impairment due to emotional stability/developmental status/cognitive deficiency (57%), failure to meet a child's immediate needs (30%), and threats of harm (14%). Three safety threats accounted for 55% of the effect of comorbid mental illness and substance abuse on safety determination: failure to meet a child's immediate needs (21%), presence of a drug-exposed infant (21%), and caretaking impairment due to emotional stability/developmental status/cognitive deficiency (14%). Results suggest that sustained linkage to effective mental health services and material resources at the outset of a child welfare case may help to promote faster and more likely reunification, and prevent future maltreatment.

Rabies is an acute encephalitis that is nearly always fatal. It is caused by infection with viruses of the genus Lyssavirus, the most common of which is Rabies lyssavirus. The Council of State and Territorial Epidemiologists (CSTE) defines a confirmed human rabies case as an illness compatible with rabies that meets at least one of five different laboratory criteria.* Four of these criteria do not depend on the patient's rabies vaccination status; however, the remaining criterion, "identification of Lyssavirus-specific antibody (i.e. by indirect fluorescent antibody…test or complete [Rabies lyssavirus] neutralization at 1:5 dilution) in the serum," is only considered diagnostic in unvaccinated patients. Lyssavirus-specific antibodies include Rabies lyssavirus-specific binding immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies and Rabies lyssavirus neutralizing antibodies (RLNAs). This report describes six patients who were tested for rabies by CDC and who met CSTE criteria for confirmed human rabies because they had illnesses compatible with rabies, had not been vaccinated for rabies, and were found to have serum RLNAs (with complete Rabies lyssavirus neutralization at a serum dilution of 1:5). An additional four patients are described who were tested for rabies by CDC who were found to have serum RLNAs (with incomplete Rabies lyssavirus neutralization at a serum dilution of 1:5) despite having not been vaccinated for rabies. None of these 10 patients received a rabies diagnosis; rather, they were considered to have been passively immunized against rabies through recent receipt of intravenous immune globulin (IVIG). Serum RLNA test results should be interpreted with caution in patients who have not been vaccinated against rabies but who have recently received IVIG.

INTRODUCTION: Understanding the spectrum and frequencies of Epstein-Barr virus (EBV) complications and markers of illness severity in immunocompetent patients with primary EBV infection will inform management of patients with EBV-related illnesses. OBJECTIVES: To determine the clinical and laboratory correlates of illness severity among infants, children and youth with infectious mononucleosis (IM). METHODS: Study subjects with confirmed IM were prospectively enrolled. Illness severity was assessed at baseline and at six weeks using a scoring tool. Peripheral blood viral loads served as a measure of viral burden. RESULTS: Among 32 children and young adults with IM, the median age was 16 years (range two to 24 years). The predominant clinical findings were lymphadenopathy (23 of 32 [72%]), pharyngitis (16 of 32 [50%]), fever (nine of 32 [28%]) and splenomegaly (six of 32 [19%]). With respect to symptoms or signs that persisted to at least six weeks after illness onset, the predominant complaint was lymphadenopathy in 35% of subjects available for reassessment. Deranged liver function tests were present at presentation in up to 44% of subjects. Patients with the highest viral loads at presentation had significantly higher illness severity scores associated with fatigue (P=0.02). Other than the scores associated with fatigue, viral load values were not significantly correlated with the illness severity scores at baseline and at six weeks. CONCLUSION: In IM, viral loads are not necessarily correlated with illness severity, with the exception of fatigue. EBV-related hepatitis is common in IM, confirming the status of this virus as a relatively common cause of transient hepatitis in children and youth. This entity is not necessarily a marker of disease severity. PMID:25371691

This study hypothesises that the presumed increased risk of self reported longstanding psychiatric illness and intake of psychotropic drugs among Iranian, Chilean, Turkish, and Kurdish adults, when these groups are compared with Polish adults, can be explained by living alone, poor acculturation, unemployment, and low sense of coherence. Data from a national sample of immigrants/refugees, who were between the ages of 20-44 years old, upon their arrival in Sweden between 1980 and 1989. Unconditional logistic regression was used in the statistical modelling. Sweden. 1059 female and 921 male migrants from Iran, Chile, Turkey, Kurdistan and Poland and a random sample of 3001 Swedes, all between the ages of 27-60 years, were interviewed in 1996 by Statistics Sweden. Compared with Swedes, all immigrants had an increased risk of self reported longstanding psychiatric illness and for intake of psychotropic drugs, with results for the Kurds being non-significant. Compared with Poles, Iranian and Chilean migrants had an increased risk of psychiatric illness, when seen in relation to a model in which adjustment was made for sex and age. The difference became non-significant for Chileans when marital status was taken into account. After including civil status and knowledge of the Swedish language, the increased risks for intake of psychotropic drugs for Chileans and Iranians disappeared. Living alone, poor knowledge of the Swedish language, non-employment, and low sense of coherence were strong risk factors for self reported longstanding psychiatric illness and for intake of psychotropic drugs. Iranian, Chilean, Turkish and Kurdish immigrants more frequently reported living in segregated neighbourhoods and having a greater desire to leave Sweden than their Polish counterparts. Evidence substantiates a strong association between ethnicity and self reported longstanding psychiatric illness, as well as intake of psychotropic drugs. This association is weakened by marital status

This study aimed to explore the psychological status and quality of life among primary caregivers of individuals suffering from various mental illnesses including early psychosis, chronic schizophrenia, depressive disorders, anxiety disorders and dementia. A total of 350 primary caregivers with relatives seeking treatment at a tertiary psychiatric hospital were recruited for this study. Socio-demographic data was obtained and the brief version of the World Health Organisation Quality of Life instrument was used to assess caregiver's quality of life (QOL). Psychological status among primary caregivers was assessed using the General Anxiety Disorder - 7 item (GAD-7) and Patient Health Questionnaire - 9 item (PHQ-9) scales. Family Interview Schedule (FIS) was used to assess the impact of caregiving relating to social problems, interpersonal strain among family members, work related problems and financial difficulties as a result of their relative's illness. The socio-demographic and clinical correlates of QOL, PHQ-9 and GAD-7 were examined using multiple linear and logistic regression analyses. Associations between QOL domains and psychological status was examined using multiple linear regression analyses. The mean age of the primary caregivers was 49.7 years (SD = 13.2), ranging from 21 to 82 years, with a preponderance of females (67.6%), aged 50-64 years old (45.7%). Majority were of Chinese ethnicity (57.5%), had secondary level education (43.1%), were married (65.2%), and employed (64.9%). 18.3% of primary caregivers had symptoms of depression (based on PHQ-9 cut-off point of 10 or greater) while 12.7% had symptoms of anxiety (based on GAD-7 cut-off point of 10 or greater). Multiple linear and logistic regression analyses revealed that primary caregivers aged between 35-49 years and 50-64 years, unemployed, living with others, providing care to those diagnosed with dementia and who had higher FIS scores were significantly more likely to report symptoms

Disorders of nutritional status in sepsis – facts and myths

Full Text Available The problem of diagnosing nutritional status disorders in septic patients remains unresolved. This is associated with the necessity of the introduction of newer and newer methods of assessing nutritional status, often requiring precise and expensive equipment as well as employment of professionals in this field in hospital wards, primarily including intensive care units (ICU. Methods that have been applied thus far for assessing nutritional status, also used in severely ill septic patients, have little impact on improving treatment results. This is due to the high dynamics of changes in nutritional status in these patients, healing process variability in individual patients, and the “mismatch” of methods for assessing nutritional status in relation to the patient’s clinical status. The diagnostic value of the traditional methods of assessing nutritional status, i.e. anthropometric analysis and selected laboratory tests, as markers of nutritional status disorders in septic patients, is still debatable. There is still no precise method that could become the “gold standard” allowing for early identification of malnutrition in these group of patients. Phase angle, bioelectrical impedance vector analysis (BIVA, and the “illness marker”, obtained directly from the resistance, reactance, and impedance, can be used as prognostic or nutritional indices in severely ill septic patients, but the intensity of research on this subject needs to be increased. Detailed assessment of nutritional status should include tests of selected inflammation markers (including TLC, HMGB1, IL-6, IL-10, IL-1ra, sTNFRI.

Full Text Available INTRODUCTION: In spite of general agreement that cross-cultural research is needed in the health area, most existing investigations of children's development of health and illness-related concepts have involved samples from developed countries. The study examined the development of the concepts of health and illness as a function of subject's age, socio-economic status (SES, gender and grade level in a Brazilian sample of 96 elementary and junior high school students. METHODS: Subjects were interviewed individually and their ideas of health and illness were assessed through open-ended questions. Participants' answers were transcribed verbatim and subjected to content analysis. RESULTS: Chi-square analyses revealed significant age, school grade and SES-related differences in participants' concepts of health and illness. DISCUSSION AND CONCLUSION: The themes employed by subjects to define both health and illness were broadly consistent with those found by previous research. The study showed a predictable relationship between subject's age and school grade level and increasingly more highly differentiated and multidimensional concepts of health and illness. This investigation suggests that, for the most part, cross-cultural similarities in children's concepts of health and illness may be more striking than the differences.

The aim of this study was to evaluate the age-appropriate immunization coverage in 366 children with chronic neurological disease (CND), to evaluate the use of vaccines not included in routine program, to evaluate serological tests for vaccine-preventable diseases and to describe the related factors in unvaccinated children. 95.6% of all children with had received age-appropriate vaccinations according to the actual National Immunization Program (NIP) during childhood. 12 children (3.6%) had not received vaccines; only two had true contraindications. Because most of the vaccines have been implemented through the NIP for 10 years in Turkey, 88% of children required these new vaccines or booster doses. Moreover, 86.6% of the children and 92.6% of household contacts had no prior history of influenza vaccine. Furthermore, 88% of the patients had not received the varicella vaccine, and the anti-varicella IgG levels were only negative in 27.9%. In addition, 18.6% of the children were negative for anti-mumps IgG, 23.7% for anti-measles IgG, and 6.3% for anti-rubella IgG. Anti-HBs IgG level was 0-10 IU/L in 45.6% of the patients (most of them previously vaccinated) and 79.8% were negative for hepatitis A IgG antibodies. For pertussis infection, the antibody titers of 54.1% of patients were below the protective level, and 10% of patients had a prior acute pertussis infection. Therefore, it is suggested that children with CND should be evaluated for their vaccination status during their first and follow-up visits at certain intervals, and their primary immunization should be completed; moreover, many will need revaccination or booster doses.

Bioflocs are rich in various probiotics and bioactive compounds, which play an important role in improving growth and health status of aquatic organisms. A 60-day experiment was conducted to investigate the effects of dietary supplementation of biofloc on growth performance, digestive enzyme activity, physiological stress, antioxidant status, expression of immune-related genes and disease resistance of sea cucumber Apostichopus japonicus. Juvenile sea cucumbers were fed five experimental diets containing graded levels of biofloc from 0% to 20% (referred as B0, B5, B10, B15 and B20, respectively). The results showed that the sea cucumbers at dietary supplementation levels of 10%-15% biofloc had significantly higher specific growth rate (SGR) compared to control group (diet B0). Digestive enzyme activity increased with the increasing of dietary biofloc level, while no significant difference was found between diets B15 and B20. Dietary supplementation of biofloc also had significant influences on physiological stress parameters except for lactate. There was no significant discrepancy in total coelomocytes counts (TCC) in coelomic fluid of sea cucumber between the treatments. Phagocytosis and respiratory burst of cellular immune at 15% and 20% biofloc levels were significantly higher than those of control group. Significant increases in superoxide dismutase (SOD), total nitric oxide synthase (T-NOS), lysozyme (LSZ), acid phosphatase (ACP) and alkaline phosphatase (AKP) activities of sea cucumber were found at highest dietary supplementation level of 20% biofloc. The expression patterns of immune-related genes (i.e., Hsp90, Hsp70, p105, Rel, NOS and LSZ) in tissues of sea cucumber were analyzed between the experimental diets, and a general trend of up-regulation was observed at higher biofloc levels. Furthermore, dietary 10%-20% biofloc significantly reduced cumulative mortality of sea cucumber after being challenged with Vibrio splendidus. In conclusion, dietary

To investigate the expression of vaginal IL-23 and its role in experimental murine vaginal candidiasis and its relationship with infection and immune status, immuno-competent (group A) and immuno-suppressed (group B) murine models of vaginal candidiasis were established in estrogen-treated mice. Non-estrogen-treated mice were used as controls (group C). The level of IL-23 p19 mRNA in murine vaginal tissue was determined by RT-PCR. Significantly increased levels of IL-23p19mRNA were observed on the 4th, the 7th and 14th day after inoculation in immuno-competent group when compared with that in control group (Pvaginal candidiasis and has a protective function during infection. Low vaginal IL-23 level may correlate with the increased susceptibility to Candida albicans in immuno-suppressed group.

Incomplete Early Childhood Immunization Series and Missing Fourth DTaP Immunizations; Missed Opportunities or Missed Visits?

Science.gov (United States)

Robison, Steve G

2013-01-01

The successful completion of early childhood immunizations is a proxy for overall quality of early care. Immunization statuses are usually assessed by up-to-date (UTD) rates covering combined series of different immunizations. However, series UTD rates often only bear on which single immunization is missing, rather than the success of all immunizations. In the US, most series UTD rates are limited by missing fourth DTaP-containing immunizations (diphtheria/tetanus/pertussis) due at 15 to 18 months of age. Missing 4th DTaP immunizations are associated either with a lack of visits at 15 to 18 months of age, or to visits without immunizations. Typical immunization data however cannot distinguish between these two reasons. This study compared immunization records from the Oregon ALERT IIS with medical encounter records for two-year olds in the Oregon Health Plan. Among those with 3 valid DTaPs by 9 months of age, 31.6% failed to receive a timely 4th DTaP; of those without a 4th DTaP, 42.1% did not have any provider visits from 15 through 18 months of age, while 57.9% had at least one provider visit. Those with a 4th DTaP averaged 2.45 encounters, while those with encounters but without 4th DTaPs averaged 2.23 encounters.

Although immunizations are efficient and cost effective methods of reducing child mortality, worldwide, approximately 2 million children die yearly of vaccine-preventable diseases. Researchers and health organizations have detailed information on the positive relationship between women's autonomy and children's health outcomes in developing countries. This study investigates the links between women's household autonomy and children's immunization status using data from a nationally representative sample of children aged 12-30 months (N = 2941) from the 2011 Ethiopia Demographic and Health Survey. The results showed that women's socioeconomic status and household autonomy were significantly associated with children's immunization status. Overall, the implications of this study align with those of the Millennium Development Goal #3: improvements in women's household autonomy are linked to more positive child health outcomes.

Comparative assessment of radiation versus nutritional and other factors that may influence immune status. Report of a Joint IAEA/WHO advisory group meeting, Vienna, Austria, 3-6 May 1994

1994-01-01

An Advisory Group Meeting was convened jointly by the International Atomic Energy Agency and the World Health Organization in May 1994 to review the role of radiation, nutrition, toxic chemicals and other factors that may influence immune status in human populations. Priorities for future research were proposed, and possibilities for using isotope in such studies were identified. The Group recommended that the IAEA should initiate a broadly based Co-ordinated Research Programme (CRP) focussed mainly on the effects of low-level radiation on immune status in human populations. The main variables of interest are (i) the level of individual radiation exposure, and (ii) the nutritional status. Possible experimental groups include persons living in areas of high radiation background (e.g. in countries where areas of high radiation background are known to occur naturally, or at high altitudes, or in areas affected by Chernobyl accident). Other possible experimental groups comprise radiation workers and uranium miners. It was also recommended that the contribution of toxic chemical exposure to immune dysfunction in these population groups should be assessed. Such research should be complemented by animal studies, and possibly also by in vitro studies with human and animal cells, by some participants in the CRP. This report has been prepared as a source of information for potential participants in the proposed CRP and for other persons associated with related programmes of the IAEA and the WHO. 15 refs, 1 fig., 7 tabs

Sick-visit immunizations and delayed well-baby visits.

2013-07-01

Giving recommended immunizations during sick visits for minor and acute illness such as acute otitis media has long been an American Academy of Pediatrics/Advisory Committee on Immunization Practice recommendation. An addition to the American Academy of Pediatrics policy in 2010 advised considering whether giving immunizations at the sick visit would discourage making up missed well-baby visits. This study quantifies the potential tradeoff between sick-visit immunizations and well-baby visits. This study was a retrospective cohort analysis with a case-control component of sick visits for acute otitis media that supplanted normal well-baby visits at age 2, 4, or 6 months. Infants were stratified for sick-visit immunization, no sick-visit immunization but quick makeup well-baby visits, or no sick-visit immunizations or quick makeup visits. Immunization rates and well-baby visit rates were assessed through 24 months of age. For 1060 study cases, no significant difference was detected in immunization rates or well-baby visits through 24 months of age between those with or without sick-visit immunizations. Thirty-nine percent of infants without a sick-visit shot failed to return for a quick makeup well-baby visit; this delayed group was significantly less likely to be up-to-date for immunizations (relative risk: 0.66) and had fewer well-baby visits (mean: 3.8) from 2 through 24 months of age compared with those with sick-visit shots (mean: 4.7). The substantial risk that infants will not return for a timely makeup well-baby visit after a sick visit should be included in any consideration of whether to delay immunizations.

Objective was to determine the immunity status of children with Bacille Calmette-Guerin (BCG) lymphadenitis (patient group) and unaffected children (control group) in Iran. We performed this longitudinal case-control study on 75 children between 2 months to 14 years old in Rasool Akram and Markaz Tebbi Hospital, Tehran, Iran during the period of 2 years (2000-2002). Ninety percent of patients had normal immunoglobulin, 10% had low level, 96.1% had normal nitro blue tetrazolium test and 3.9% had lower activity. There was a significant difference in the total lymphocyte CD3,CD8, CD19, CD16/CD56 and natural killers (NK) cell but no significant difference in the CD4/CD8 ratio and CD4 between case (n=75) and control (n=100) groups. Thirty-eight cases with mild lymphoenia, isolated CD4, CD3, CD19, NK cells (CD16/CD56) deficiency in 3 (22%); idiopathic disseminated BCG infection (unknown immunodeficiency type) in 3 (22%) patients were observed. Thirty-eight cases are diagnosed as mild immune deficient without any previous recurrent infections (mild lymphopenia; Isolated CD4; CD3 or CD19 deficiency. Natural killers (CD16/CD56) deficiency in 3 (22%); idiopathic disseminated BCG infection (unknown immunodeficiency type) in 3 (22%) patients. The natural killers (CD16/CD56) deficient cases respond well to 3 antimycobacterial drugs without immunomodulator. Natural killer's cells deficiency not yet reported as a risk factor for progression and complication of BCG infection. All cases of idiopathic disseminated BCG infection (unknown immunodeficiency type) with nonlethal and indulgent BCG infections responded well to needle aspiration and antimycobacterial drugs with immunomodulator (gamma interferon). In cases with multiple and recurrent BCG lymphadenitis without any previous recurrent infection complete immunological studies should be carried out. Most cases with mild immune deficiency usually response well to needle aspiration alone or combine with antimycobacterial drugs. The

Gender-Atypical Mental Illness as Male Gender Threat.

The present study examined whether men view gender-atypical (i.e., feminine) psychological disorders as threats to their gender status. Men and women (N = 355) rated their expectations of gender status loss, feelings of distress, and help-seeking intentions in response to 10 different stereotypically masculine and feminine psychological disorders. Men as compared to women expected greater gender status loss for, and reported more distress to, gender-atypical versus gender-typical disorders. Expectations of gender status loss partially mediated the link between participant gender and distress at the thought of gender-atypical disorders. These findings suggest that feminine disorders pose more powerful gender status threats for men than masculine disorders do and that men's expectations of gender status loss for feminine disorders drive their negative reactions to these mental illnesses. The discussion emphasizes the importance of considering the gender-typicality of disorders, and the implications of these findings for clinical interventions. © The Author(s) 2015.

The preparticipation physical evaluation (PPE) often serves as the only preventive health care visit for athletes, but immunization status is not uniformly addressed in such visits. Thus, athletes may not be receiving recommended immunizations. Our aim was to determine the proportion of high school senior athletes who received all recommended immunizations. Our hypothesis was that females would be less likely than males to receive all recommended immunizations given suboptimal human papillomavirus (HPV) vaccine uptake. We conducted a cross-sectional survey evaluation of the immunization status of high school senior athletes in Davidson County, TN. The primary composite outcome was receipt of recommended immunizations for tetanus, meningococcal, and seasonal influenza. For females, the primary outcome also included completion of the HPV series. A total of 162 participants, 104 males and 58 females, were included. More males than females received all recommended immunizations (15.4% vs 3.5%; P = 0.02). When HPV immunization was excluded from the composite outcome, there was no difference in the proportion of males and females who received all recommended immunizations (15.4% vs 15.5%; P = 0.98). The odds of receiving all recommended immunizations was 0.14 (95% CI, 0.03-0.72) for females compared with males when adjusted for covariates. Athletes seen at retail-based clinics for their PPE were less likely to receive all recommended immunizations compared with athletes seen in primary care (OR, 0.13; 95% CI, 0.02-0.69). Only 1 in 6 high school senior athletes received the recommended tetanus, meningococcal, and influenza immunizations. A lower proportion of females, only 1 in 28, received all recommended immunizations due to the HPV series. Policy changes requiring a review of immunizations at the PPE would benefit many high school athletes.

The social distribution of illness: is Australia more equal?

Broom, D H

1984-01-01

The relationship between socioeconomic status and ill health has challenged researchers and health practitioners for many years. This paper outlines the way several basic measures of morbidity are related to occupation, income and education, with brief attention to class gradients in mortality and service utilization. The international literature contains many studies showing an inverse gradient in health by social standing: people who are socially and economically well off typically enjoy good health as well. Data from a recent health survey conducted in New South Wales, Australia do not confirm the British findings when occupational categories are studied, but when other measures of status are substituted for the crude occupation categories, a number of patterns appear. Income is significantly associated with the probability of chronic illness among middle-aged men and women, and among women over 65. The predicted pattern is also evident for recent illness among young men and for consulting among elderly respondents, but these associations are not statistically significant. Except among the elderly, better educated men and women are healthier than those with less education on most morbidity measures. The parallels and discrepancies between these findings from an Australian sample and overseas studies raise important research and policy questions.

Summary Economic analyses of cholera immunization programmes require estimates of the costs of cholera. The Diseases of the Most Impoverished programme measured the public, provider, and patient costs of culture-confirmed cholera in four study sites with endemic cholera using a combination of hospital- and community-based studies. Families with culture-proven cases were surveyed at home 7 and 14 days after confirmation of illness. Public costs were measured at local health facilities using a micro-costing methodology. Hospital-based studies found that the costs of severe cholera were USD 32 and 47 in Matlab and Beira. Community-based studies in North Jakarta and Kolkata found that cholera cases cost between USD 28 and USD 206, depending on hospitalization. Patient costs of illness as a percentage of average monthly income were 21% and 65% for hospitalized cases in Kolkata and North Jakarta, respectively. This burden on families is not captured by studies that adopt a provider perspective. PMID:21554781

To investigate how a terminal illness may affect the health-care providers' resuscitation preferences. We conducted a cross-sectional survey in 9 health-care institutions located in 4 geographical regions in North and Central America, investigating attitudes toward end-of-life practices in health-care providers. Statistical analysis included descriptive statistics and χ 2 test for the presence of associations ( P < 0.05 being significant) and Cramer V for the strength of the association. The main outcome measured the correlation between the respondents' present code status and their preference for cardiopulmonary resuscitation (CPR) in case of terminal illness. A total of 852 surveys were completed. Among the respondents, 21% (n = 180) were physicians, 36.9% (n = 317) were nurses, 10.5% (n = 90) were medical students, and 265 participants were other staff members of the institutions. Most respondents (58.3%; n = 500) desired "definitely full code" (physicians 73.2%; n = 131), only 13.8% of the respondents (physicians 8.33%; n = 15) desired "definitely no code" or "partial support," and 20.9% of the respondents (n = 179; among physicians 18.4%; n = 33) had never considered their code status. There was an association between current code status and resuscitation preference in case of terminal illness ( P < .001), but this association was overall quite weak (Cramer V = 0.180). Subgroup analysis revealed no association between current code status and terminal illness code preference among physicians ( P = .290) and nurses ( P = .316), whereupon other hospital workers were more consistent ( P < .01, Cramer V = .291). Doctors and nurses have different end-of-life preferences than other hospital workers. Their desire to undergo CPR may change when facing a terminal illness.

The Gut as the Motor of Multiple Organ Dysfunction in Critical Illness.

Science.gov (United States)

Klingensmith, Nathan J; Coopersmith, Craig M

2016-04-01

All elements of the gut - the epithelium, the immune system, and the microbiome - are impacted by critical illness and can, in turn, propagate a pathologic host response leading to multiple organ dysfunction syndrome. Preclinical studies have demonstrated that this can occur by release of toxic gut-derived substances into the mesenteric lymph where they can cause distant damage. Further, intestinal integrity is compromised in critical illness with increases in apoptosis and permeability. There is also increasing recognition that microbes alter their behavior and can become virulent based upon host environmental cues. Gut failure is common in critically ill patients; however, therapeutics targeting the gut have proven to be challenging to implement at the bedside. Numerous strategies to manipulate the microbiome have recently been used with varying success in the ICU. Copyright © 2016 Elsevier Inc. All rights reserved.

In modern critical care, the paradigm of 'therapeutic nutrition' is replacing traditional 'supportive nutrition'. Standard enteral formulas meet basic macro- and micronutrient needs; therapeutic enteral formulas meet these basic needs and also contain specific pharmaconutrients that may attenuate hyperinflammatory responses, enhance the immune responses to infection, or improve gastrointestinal tolerance. Choosing the right enteral feeding formula may positively affect a patient's outcome; targeted use of therapeutic formulas can reduce the incidence of infectious complications, shorten lengths of stay in the ICU and in the hospital, and lower risk for mortality. In this paper, we review principles of how to feed (enteral, parenteral, or both) and when to feed (early versus delayed start) patients who are critically ill. We discuss what to feed these patients in the context of specific pharmaconutrients in specialized feeding formulations, that is, arginine, glutamine, antioxidants, certain ω-3 and ω-6 fatty acids, hydrolyzed proteins, and medium-chain triglycerides. We summarize current expert guidelines for nutrition in patients with critical illness, and we present specific clinical evidence on the use of enteral formulas supplemented with anti-inflammatory or immune-modulating nutrients, and gastrointestinal tolerance-promoting nutritional formulas. Finally, we introduce an algorithm to help bedside clinicians make data-driven feeding decisions for patients with critical illness. PMID:22136305

Full Text Available Background: Stigma associated with mental illnesses is one of the principal causes for mentally ill people not receiving adequate mental health care and treatment. The study was conducted to assess the extent of stigma associated with mental illness and knowledge of mental illness among the community. Materials and Methods: Community-based, cross-sectional study was conducted among 445 respondents from Udupi district; the community attitude toward the mentally ill (CAMI scale was used to assess stigma. The probability proportional to sampling size technique was adopted to select the wards/blocks. Household from blocks/wards were selected using convenience sampling. Self- administered semi-structured questionnaire was used to collect the information. Data was analyzed using the software SPSS version 15. Results: Of the total 445 respondents, the prevalence of stigma toward mentally ill people was 74.61% (95% confidence interval, 0.7057, 0.7866. The prevalence of stigma was high under all the four domains of CAMI scale. High prevalence of stigma was seen among females and people with higher income. Conclusions: The overall prevalence of stigma toward PWMI was found to be high. The stigma toward PWMI was associated with gender with respect to AU, BE and CMHI. Hence, the study suggests that there is a strong need to eliminate stigma associated with mental illness to improve the mental health status of the region.

The Global Polio Eradication Initiative (GPEI) currently based on use of oral poliovirus vaccine (OPV) has identified suboptimal immunogenicity of this vaccine as a major impediment to eradication, with a failure to induce protection against paralytic poliomyelitis in certain population segments in some parts of the world. The Mucosal Immunity and Poliovirus Vaccines: Impact on Wild Poliovirus Infection, Transmission and Vaccine Failure conference was organized to obtain a better understanding of the current status of global control of poliomyelitis and identify approaches to improve the immune responsiveness and effectiveness of the orally administered poliovirus vaccines in order to accelerate the global eradication of paralytic poliomyelitis.

Clinical-immunological surveillance of persons taking part in accident effect elimination realized 5 years later has shown that the most characteristic clinical symptocomplex for the persons examined remains the syndrome of increased fatiguability. Supression of the immune status cell link expressed in lowering the mean values of T-lymphocytes is revealed for the persons examined 5 years later. It may be supposed that the fifth year is the critical period in which T-cell immune deficits develop for more than one third of persons subjected to the effects of the complex of severe radiation accident factors. 5 refs.; 6 figs.; 4 tabs

Full Text Available Objectives: Several epidemiological studies on medical care utilization prior to suicide have considered the motivation of suicide, but focused on the influence of physical illnesses. Medical care expenditure in suicide completers with non-illness-related causes has not been investigated. Methods: Suicides motivated by non-illness-related factors were identified using the investigator’s note from the National Police Agency, which was then linked to the Health Insurance Review and Assessment data. We investigated the medical care expenditures of cases one year prior to committing suicide and conducted a case-control study using conditional logistic regression analysis after adjusting for age, gender, area of residence, and socioeconomic status. Results: Among the 4515 suicides motivated by non-illness-related causes, medical care expenditures increased in only the last 3 months prior to suicide in the adolescent group. In the younger group, the proportion of total medical expenditure for external injuries was higher than that in the older groups. Conditional logistic regression analysis showed significant associations with being a suicide completer and having a rural residence, low socioeconomic status, and high medical care expenditure. After stratification into the four age groups, a significant positive association with medical care expenditures and being a suicide completer was found in the adolescent and young adult groups, but no significant results were found in the elderly groups for both men and women. Conclusions: Younger adults who committed suicide motivated by non-illness-related causes had a higher proportion of external injuries and more medical care expenditures than their controls did. This reinforces the notion that suicide prevention strategies for young people with suicidal risk factors are needed.

The immune system, natural autoantibodies and general homeostasis in health and disease.

Poletaev, A; Boura, P

2011-10-01

It is generally accepted that the destination of the immune system is not only to discriminate between self and non-self but also to mount responses against non-self. During the last decades, it became evident that weak self-reactivity is a necessary condition for immune homeostasis. Natural self reactivity and the internal image created by autoantibodies, participate greatly to the maintenance of homeostasis. Under conditions of increased or altered antigenic pressure, the homeostatic status is disrupted and the organism becomes vulnerable to the emergence of diseases. "Immunculus" is the self-reactive and interconnected entity of the immune system, provided by a complicated network of natural autoantibobies of different specificity, as a mosaic picture. Quantitative changes in each part of the image are related to variations of expression of relative antigens. The immune system takes in account image information from the continuous screening of the antigenic status and compares between presented state and the desired (optimal) one. Substantial and prolonged deviations from the optimal state, triggers the induction of compensatory and reparative processes, aiming to restore molecular and functional homeostasis. So, natural autoimmunity through the ability of natural a-Abs to induce mechanisms of natural and acquired immunity, aims to prevent pathogenic processes and maintain or restore health status.

Dscam1 in Pancrustacean Immunity: Current Status and a Look to the Future

Full Text Available The Down syndrome cell adhesion molecule 1 (Dscam1 gene is an extraordinary example of diversity: by combining alternatively spliced exons, thousands of isoforms can be produced from just one gene. So far, such diversity in this gene has only been found in insects and crustaceans, and its essential part in neural wiring has been well-characterized for Drosophila melanogaster. Ten years ago evidence from D. melanogaster showed that the Dscam1 gene is involved in insect immune defense and work on Anopheles gambiae indicated that it is a hypervariable immune receptor. These exciting findings showed that via processes of somatic diversification insects have the possibility to produce unexpected immune molecule diversity, and it was hypothesized that Dscam1 could provide the mechanistic underpinnings of specific immune responses. Since these first publications the quest to understand the function of this gene has uncovered fascinating insights from insects and crustaceans. However, we are still far from a complete understanding of how Dscam1 functions in relation to parasites and pathogens and its full relevance for the immune system. In this Hypothesis and Theory article, we first briefly introduce Dscam1 and what we know so far about how it might function in immunity. By focusing on seven questions, we then share our sometimes contrasting thoughts on what the evidence tells us so far, what essential experiments remain to be done, and the future prospects, with the aim to provide a multiangled view on what this fascinating gene has to do with immune defense.

The complexity of the cases of critically ill polytrauma patients is given by both the primary, as well as the secondary, post-traumatic injuries. The severe injuries of organ systems, the major biochemical and physiological disequilibrium, and the molecular chaos lead to a high rate of morbidity and mortality in this type of patient. The 'gold goal' in the intensive therapy of such patients resides in the continuous evaluation and monitoring of their clinical status. Moreover, optimizing the therapy based on the expression of certain biomarkers with high specificity and sensitivity is extremely important because of the clinical course of the critically ill polytrauma patient. In this paper we wish to summarize the recent studies of biomarkers useful for the intensive care unit (ICU) physician. For this study the available literature on specific databases such as PubMed and Scopus was thoroughly analyzed. Each article was carefully reviewed and useful information for this study extracted. The keywords used to select the relevant articles were "sepsis biomarker", "traumatic brain injury biomarker" "spinal cord injury biomarker", "inflammation biomarker", "microRNAs biomarker", "trauma biomarker", and "critically ill patients". For this study to be carried out 556 original type articles were analyzed, as well as case reports and reviews. For this review, 89 articles with relevant topics for the present paper were selected. The critically ill polytrauma patient, because of the clinical complexity the case presents with, needs a series of evaluations and specific monitoring. Recent studies show a series of either tissue-specific or circulating biomarkers that are useful in the clinical status evaluation of these patients. The biomarkers existing today, with regard to the critically ill polytrauma patient, can bring a significant contribution to increasing the survival rate, by adapting the therapy according to their expressions. Nevertheless, the necessity remains to

A role for homeostatic drive in the perpetuation of complex chronic illness: Gulf War Illness and chronic fatigue syndrome.

Directory of Open Access Journals (Sweden)

Travis J A Craddock

Full Text Available A key component in the body's stress response, the hypothalamic-pituitary-adrenal (HPA axis orchestrates changes across a broad range of major biological systems. Its dysfunction has been associated with numerous chronic diseases including Gulf War Illness (GWI and chronic fatigue syndrome (CFS. Though tightly coupled with other components of endocrine and immune function, few models of HPA function account for these interactions. Here we extend conventional models of HPA function by including feed-forward and feedback interaction with sex hormone regulation and immune response. We use this multi-axis model to explore the role of homeostatic regulation in perpetuating chronic conditions, specifically GWI and CFS. An important obstacle in building these models across regulatory systems remains the scarcity of detailed human in vivo kinetic data as its collection can present significant health risks to subjects. We circumvented this using a discrete logic representation based solely on literature of physiological and biochemical connectivity to provide a qualitative description of system behavior. This connectivity model linked molecular variables across the HPA axis, hypothalamic-pituitary-gonadal (HPG axis in men and women, as well as a simple immune network. Inclusion of these interactions produced multiple alternate homeostatic states and sexually dimorphic responses. Experimental data for endocrine-immune markers measured in male GWI subjects showed the greatest alignment with predictions of a naturally occurring alternate steady state presenting with hypercortisolism, low testosterone and a shift towards a Th1 immune response. In female CFS subjects, expression of these markers aligned with an alternate homeostatic state displaying hypocortisolism, high estradiol, and a shift towards an anti-inflammatory Th2 activation. These results support a role for homeostatic drive in perpetuating dysfunctional cortisol levels through persistent

A substantial body of work has related survey-based parental vaccine hesitancy to noncompliant childhood immunization. However little attention has been paid to the connection between parents' own immunization behavior and the immunizations their children receive. Using the Oregon ALERT Immunization Information System, we identified adult caregiver-child pairs for children between 9 months and 17 years of age. The likelihood of adult-child concordance of influenza immunization per influenza season from 2010-2011 through 2014-2015 was assessed. The utility of adult immunization as a predictor was also assessed for other, noninfluenza recommended immunizations for children and adolescents. A total of 450 687 matched adult caregiver-child pairs were included in the study. The children of immunizing adults were 2.77 times more likely to also be immunized for seasonal influenza across all seasons (95% confidence interval, 2.74-2.79), with similar results applying within each season. Adult immunization status was also significantly associated with the likelihood of children and adolescents getting other noninfluenza immunizations, such as the human papillomavirus vaccine (HPV). When adults improved their own behavior from nonimmunizing to immunizing across influenza seasons, their children if not immunized in the previous season were 5.44 times (95% confidence interval, 5.35-5.53) more likely to become immunized for influenza. Children's likelihood of following immunization recommendations is associated with the immunization behavior of their parents. Encouraging parental immunization is a potential tool for increasing children's immunization rates. Copyright © 2017 by the American Academy of Pediatrics.

To investigate a framework of correlates of both mental illness and wellbeing in a large, current, and nationally representative sample of children in the United Kingdom. An ecologic framework of correlates including individual (sociodemographic and human capital), family, social, and wider environmental factors were examined in 12,347 children aged 11 years old from the UK Millennium Cohort Study. Mental illness and wellbeing scores were standardized to allow comparisons, and the variance explained by the different predictors was estimated. Mental illness and wellbeing were weakly correlated in children (r = 0.2), and their correlates were similar in some instances (e.g., family structure, sibling bullying, peer problems) but differed in others (e.g., family income, perceived socioeconomic status, cognitive ability, health status, neighborhood safety). The predictors included in the study explained 47% of the variance in symptoms of mental illness, with social relationships, home environment, parent health, cognitive ability, socioeconomic status, and health factors predicting large amounts of variance. A comparatively lower 26% of the variance in wellbeing was explained by the study variables, with wider environment, social relationships, perceived socioeconomic status, and home environment predicting the most variance. Correlates of children's mental illness and wellbeing are largely distinct, stressing the importance of considering these concepts separately and avoiding their conflation. This study highlights the relevance of these findings for understanding social gradients in mental health through the life course and the conceptualization and development of mental illness and wellbeing in childhood as precursors to lifelong development in these domains.

The role of immune mechanisms in Tourette syndrome.

Science.gov (United States)

Martino, Davide; Zis, Panagiotis; Buttiglione, Maura

2015-08-18

Tourette syndrome (TS) is a childhood-onset tic disorder associated with abnormal development of brain networks involved in the sensory and motor processing. An involvement of immune mechanisms in its pathophysiology has been proposed. Animal models based on active immunization with bacterial or viral mimics, direct injection of cytokines or patients' serum anti-neuronal antibodies, and transgenic approaches replicated stereotyped behaviors observed in human TS. A crucial role of microglia in the neural-immune crosstalk within TS and related disorders has been proposed by animal models and confirmed by recent post mortem studies. With analogy to autism, genetic and early life environmental factors could foster the involvement of immune mechanisms to the abnormal developmental trajectories postulated in TS, as well as lead to systemic immune dysregulation in this condition. Clinical studies demonstrate an association between TS and immune responses to pathogens like group A Streptococcus (GAS), although their role as risk-modifiers is still undefined. Overactivity of immune responses at a systemic level is suggested by clinical studies exploring cytokine and immunoglobulin levels, immune cell subpopulations, and gene expression profiling of peripheral lymphocytes. The involvement of autoantibodies, on the other hand, remains uncertain and warrants more work using live cell-based approaches. Overall, a body of evidence supports the hypothesis that disease mechanisms in TS, like other neurodevelopmental illnesses (e.g. autism), may involve dysfunctional neural-immune cross-talk, ultimately leading to altered maturation of brain pathways controlling different behavioral domains and, possibly, differences in organising immune and stress responses.

Tactical trainees, like those entering the police force, are required to undergo vigorous training as part of their occupational preparation. This training has the potential to cause injuries. In addition, the physical training, communal living and pressures of tactical training are known to induce immune suppression and have the potential to increase the risk of illness. The aim of this study was to investigate the relationship between leg power, as measured by a vertical jump (VJ), and rates of reported injuries and illnesses during police recruit training. Retrospective data from recruits (n = 1021) undergoing basic police recruit training at an Australian Police Force College was collected. Recruits completed a VJ assessment at the commencement of their second state of training. Formally reported illness and injuries were collected 12 weeks later, following completion of training. Correlations between VJ height and rates of reported illness and injury were low (r = -0.16 and -0.09, respectively) but significant (p Police recruits with lower VJ height are at a significantly greater risk of suffering an injury or illness during police basic recruit training.

Intestinal crosstalk – a new paradigm for understanding the gut as the “motor” of critical illness

Science.gov (United States)

Clark, Jessica A; Coopersmith, Craig M

2007-01-01

For more than 20 years, the gut has been hypothesized to be the “motor” of multiple organ dysfunction syndrome (MODS). As critical care research has evolved, there have been multiple mechanisms by which the gastrointestinal tract has been proposed to drive systemic inflammation. Many of these disparate mechanisms have proved to be important in the origin and propagation of critical illness. However, this has led to an unusual situation where investigators describing the gut as a “motor” revving the systemic inflammatory response syndrome (SIRS) are frequently describing wholly different processes to support their claim (i.e. increased apoptosis, altered tight junctions, translocation, cytokine production, crosstalk with commensal bacteria, etc). The purpose of this review is to present a unifying theory as to how the gut drives critical illness. Although the gastrointestinal tract is frequently described simply as “the gut,” it is actually made up of a) an epithelium, b) a diverse and robust immune arm, which contains the majority of immune cells in the body, and c) the commensal bacteria, which contain more cells than are present in the entire host organism. We propose that the intestinal epithelium, the intestinal immune system and the intestine’s endogenous bacteria all play vital roles driving MODS, and the complex crosstalk between these three interrelated portions of the gastrointestinal tract are cumulatively what makes the gut a “motor” of critical illness.

Dialysis therapy is extremely stressful as it interferes with all spheres of daily activities of the patients. This study is aimed at understanding the perceived illness intrusion among patients on hemodialysis (HD) and to find the association between illness intrusion and patient demo-graphics as well as duration of dialysis. A cross sectional study involving 90 patients with chronic kidney disease (CKD) stage V, on HD was performed during the period from 2005 to 2006. The subjects included were above 18 years of age, willing, stable and on dialysis for at least two months. Patients with psychiatric co-morbidity were excluded. A semi-structured interview schedule covering sociodemographics and a 13 item illness intrusion checklist covering the various aspects of life was carried out. The study patients were asked to rate the illness intrusion and the extent. The data were analyzed statistically. The mean age of the subjects was 50.28 + - 13.69 years, males were predominant (85%), 73% were married, 50% belonged to Hindu religion, 25% had pre-degree education, 25% were employed and 22% were housewives. About 40% and 38% of the study patients belonged to middle and upper socio-economic strata respectively; 86% had urban background and lived in nuclear families. The mean duration on dialysis was 24 + - 29.6 months. All the subjects reported illness intrusion to a lesser or greater extent in various areas including: health (44%), work (70%) finance (55%), diet (50%) sexual life (38%) and psychological status (25%). Illness had not intruded in areas of relationship with spouse (67%), friends (76%), family (79%), social (40%) and religious functions (72%). Statistically significant association was noted between illness intrusion and occupation (P= 0.02). (author)

2015-01-01

The activation status of platelets in Immune Thrombocytopenia (ITP) patients--which is still somewhat controversial--is of potential interest, because activated platelets tend to aggregate (leading to excessive clotting or thromboembolic events) but cannot do so when platelet numbers are low, as in ITP. Although corticosteroids are the first line of therapy in ITP, the effect of steroids on activation of platelets has not been evaluated so far. We examined the status of platelet activation (with and without stimulation with ADP) in ITP patients, at the start of therapy (pre-steroid treatment, naive) and post-steroid treatment (classified on the basis of steroid responsiveness). We used flow cytometry to evaluate the levels of expression of P-selectin, and PAC-1 binding to platelets of 55 ITP patients and a similar number of healthy controls, treated with and without ADP. We found that platelets in ITP patients exist in an activated state. In patients who are responsive to steroids, the treatment reverses this situation. Also, the fold activation of platelets upon treatment with ADP is more in healthy controls than in ITP patients; treatment with steroids causes platelets in steroid-responsive patients to become more responsive to ADP-activation, similar to healthy controls. Thus steroids may cause changes in the ability of platelets to get activated with an agonist like ADP. Our results provide new insights into how, and why, steroid therapy helps in the treatment of ITP.

Problematic internet use has been associated with a variety of psychological comorbidities, but it relationship with physical illness has not received the same degree of investigation. The current study surveyed 505 participants online, and asked about their levels of problematic internet usage (Internet Addiction Test), depression and anxiety (Hospital Anxiety and Depression Scales), social isolation (UCLA Loneliness Questionnaire), sleep problems (Pittsburgh Sleep Quality Index), and their current health - General Health Questionnaire (GHQ-28), and the Immune Function Questionnaire. The results demonstrated that around 30% of the sample displayed mild or worse levels of internet addiction, as measured by the IAT. Although there were differences in the purposes for which males and females used the internet, there were no differences in terms of levels of problematic usage between genders. The internet problems were strongly related to all of the other psychological variables such as depression, anxiety, social-isolation, and sleep problems. Internet addiction was also associated with reduced self-reported immune function, but not with the measure of general health (GHQ-28). This relationship between problematic internet use and reduced immune function was found to be independent of the impact of the co-morbidities. It is suggested that the negative relationship between level of problematic internet use and immune function may be mediated by levels of stress produced by such internet use, and subsequent sympathetic nervous activity, which related to immune-supressants, such as cortisol.

The current study surveyed 505 participants online, and asked about their levels of problematic internet usage (Internet Addiction Test, depression and anxiety (Hospital Anxiety and Depression Scales, social isolation (UCLA Loneliness Questionnaire, sleep problems (Pittsburgh Sleep Quality Index, and their current health - General Health Questionnaire (GHQ-28, and the Immune Function Questionnaire. The results demonstrated that around 30% of the sample displayed mild or worse levels of internet addiction, as measured by the IAT. Although there were differences in the purposes for which males and females used the internet, there were no differences in terms of levels of problematic usage between genders. The internet problems were strongly related to all of the other psychological variables such as depression, anxiety, social-isolation, and sleep problems. Internet addiction was also associated with reduced self-reported immune function, but not with the measure of general health (GHQ-28. This relationship between problematic internet use and reduced immune function was found to be independent of the impact of the co-morbidities. It is suggested that the negative relationship between level of problematic internet use and immune function may be mediated by levels of stress produced by such internet use, and subsequent sympathetic nervous activity, which related to immune-supressants, such as cortisol.

Problematic internet use has been associated with a variety of psychological comorbidities, but it relationship with physical illness has not received the same degree of investigation. The current study surveyed 505 participants online, and asked about their levels of problematic internet usage (Internet Addiction Test), depression and anxiety (Hospital Anxiety and Depression Scales), social isolation (UCLA Loneliness Questionnaire), sleep problems (Pittsburgh Sleep Quality Index), and their current health – General Health Questionnaire (GHQ-28), and the Immune Function Questionnaire. The results demonstrated that around 30% of the sample displayed mild or worse levels of internet addiction, as measured by the IAT. Although there were differences in the purposes for which males and females used the internet, there were no differences in terms of levels of problematic usage between genders.

The authors studied 10 cases of amoebic hepatic abscess documented by clinical evidence and confirmed by laboratory tests, liver scan and a good response to treatment. The immunological state of the patients was determined by protein electrophoresis, immunoelectrophoresis, counter-immunoelectrophoresis, radial immunodiffusion and roset formation for T and B lymphocytes. It is concluded that the alterations of cellular and humoral immunity is evident in cases of amoebic hepatic abscess; this alterations are more clear in the acute form of the illness and the immunological deficiency is more significant in the celular immunity.

During the last decade, a large number of human tumour antigens have been identified. These antigens are classified as tumour-specific shared antigens, tissue-specific differentiation antigens, overexpressed antigens, tumour antigens resulting from mutations, viral antigens and fusion proteins. Antigens recognised by effectors of immune system are potential targets for antigen-specific cancer immunotherapy. However, most tumour antigens are self-proteins and are generally of low immunogenicity and the immune response elicited towards these tumour antigens is not always effective. Strategies to induce and enhance the tumour antigen-specific response are needed. This review will summarise the approaches to discovery of tumour antigens, the current status of tumour antigens, and their potential application to cancer treatment.

The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.

Protection against vaccine-preventable diseases is important in children with inflammatory bowel disease (IBD) due to frequent immunosuppressive therapy use. The chronic relapsing nature and treatment regimen of IBD may necessitate modified timing of immunizations. To evaluate the completeness of immunizations in children with IBD. Immunization records of all children with IBD followed at the Alberta Children's Hospital (Calgary, Alberta) were reviewed. For children with incomplete immunization according to the province of Alberta schedule, the reasons for such were clarified. Demographic data and age at diagnosis were also collected. Immunization records were obtained from 145 (79%) children with IBD. Fifteen children had incomplete routine childhood immunizations, including two with no previous immunizations. The most common incomplete immunizations included hepatitis B (n=9), diphtheria, tetanus, acellular pertussis at 14 to 16 years of age (n=7), and diphtheria, tetanus, acellular pertussis, inactivated polio at four to six years of age (n=6). The reasons for incomplete immunization included use of immunosuppressive therapy at time of scheduled immunization; IBD-related symptoms at time of scheduled immunization; parental refusal; recent move from elsewhere with different immunization schedule; unawareness of routine immunization; and needle phobia. Although the majority of children with IBD had complete childhood immunizations, suboptimal immunizations were present in 10%. With increasing use of immunosuppressive therapy in IBD, physicians caring for children with IBD must periodically evaluate immunization status and ensure the completeness of childhood immunizations.

Mixed-breed rabbits in Poland are widely used for diagnostic and scientific research and as utility animals, therefore there is a need to know their immunological status, as well as their haematological status. In this study natural immunity factors were analyzed in Polish mixed-breed rabbits and Polish mixed-breed rabbits with addition of blood of meet-breed, considering the impact of sex and season of the year (spring, summer, autumn, winter) using measurement of non-specific cellular and humoral immunity parameters in peripheral blood. The study has revealed that there is a variety between the two commonly used mixed-breed types of rabbits, especially when sex and season is concerned, which is crucial for using these animals in experiments.

The apoptosis pathway of programmed cell death is frequently deregulated in cancer. An intact apoptosis pathway is required for proper response to anti-cancer treatment. We investigated the chromatin status of key apoptosis genes in the apoptosis pathway in colorectal cancer cell lines in relation to apoptosis induced by chemo-, immune- or radiation therapy. Using chromatin immunoprecipitation (ChIP), we measured the presence of transcription-activating histone modifications H3Ac and H3K4me3 and silencing modifications H3K9me3 and H3K27me3 at the gene promoter regions of key apoptosis genes Bax, Bcl2, Caspase-9, Fas (CD95) and p53. Cell lines DLD1, SW620, Colo320, Caco2, Lovo and HT29 were treated with cisplatin, anti-Fas or radiation. The apoptotic response was measured by flow cytometry using propidium iodide and annexin V-FITC. The chromatin status of the apoptosis genes reflected the activation status of the intrinsic (Bax, Bcl2, Caspase-9 and p53) and extrinsic (Fas) pathways. An active intrinsic apoptotic pathway corresponded to sensitivity to cisplatin and radiation treatment of cell lines DLD1, SW620 and Colo320. An active Fas promoter corresponded to an active extrinsic apoptotic pathway in cell line DLD1. mRNA expression data correlated with the chromatin status of the apoptosis genes as measured by ChIP. In conclusion, the results presented in this study indicate that the balance between activating and silencing histone modifications, reflecting the chromatin status of apoptosis genes, can be used to predict the response of tumor cells to different anti-cancer therapies and could provide a novel target to sensitize tumors to obtain adequate treatment responses.

Full Text Available A few months from the time of this survey, the nearly completed inpatient psychiatric facility within the Aminu Kano Teaching Hospital’s complex would be ready for admissions. Understanding the health workers’ level of experience of mental illness and their likely behavioural responses towards people with psychiatric illness, therefore, should be a good baseline to understanding their likely reactions towards admitting such patients within a general hospital setting. The study, which used a pre-tested and adapted attribution questionnaire, was pro­spective and cross-sectional. Randomly selected health workers in Aminu Kano Teaching Hospital had their level of familiarity and attributions towards psychiatric patients assessed. The respondents showed a high level of experience with mental illness, with more than 3 in 5 of them having watched movies on mental illness before. More than half of them held positive (favorable attributions towards persons with mental illness on nine of the ten assessed attribution factors. Almost all held negative (unfavourable opinion towards intimate relationships with such persons. Attribution factors, “Responsibility, “Anger”, “Dangerousness”, “Fear” and “Segregation” were significantly related to the respondents’ level of education (P less than 0.05. Marital status of the respondents related significantly to “Pity” and “Avoidance” factors (P less than 0.05. Having watched movies on mental illness significantly related to “Responsibility” and “Fear” factors (P less than 0.05. Programs designed to improve the health workers mental health literacy, and increased positive professional contacts with mentally ill persons on treatment, would further enhance their perceived positive attributions towards them.

Full Text Available Influenza viruses belong to the family Orthomyxoviridae of enveloped viruses and are an important cause of respiratory infections worldwide. The influenza virus is able to infect a wide variety species as diverse as poultry, marine, pigs, horses and humans. Upon infection with influenza virus the innate immunity plays a critical role in efficient and rapid control of viral infections as well as in adaptive immunity initiation. The humoral immune system produces antibodies against different influenza antigens, of which the HA-specific antibody is the most important for neutralization of the virus and thus prevention of illness. Cell mediated immunity including CD4+ helper T cells and CD8+ cytotoxic T cells are the other arms of adaptive immunity induced upon influenza virus infection. The complex inherited factors and age related changes are associated with the host immune responses. Here, we review the different components of immune responses against influenza virus. Additionally, the correlation of the immune response to age and inherited factors has been discussed. These determinations lead to a better understanding of the limitations of immune responses for developing improved vaccines to control influenza virus infection.

To define the relationship between worsening oxygenation status (worst PaO(2)/FiO(2) ratio in the first 24 hours after intensive care unit admission) and mortality in immunosuppressed and immunocompetent ICU patients in the presence and absence of mechanical ventilation. Retrospective cohort study. Data were extracted from the Australian and New Zealand Intensive Care Society Adult Patient Database. Adult patients admitted to 129 ICUs in Australasia, 2000-2010. In hospital and ICU mortality; relationship between mortality and declining PaO(2)/FiO(2) ratio by ventilation status and immune status. 457 750 patient records were analysed. Worsening oxygenation status was associated with increasing mortality in all groups. Higher mortality was seen in immunosuppressed patients than immunocompetent patients. After multivariate analysis, in mechanically ventilated patients, declining PaO(2)/FiO(2) ratio in the first 24 hours of ICU admission was associated with a more rapidly rising mortality rate in immunosuppressed patients than non-immunosuppressed patients. Immunosuppression did not affect the relationship between oxygenation status and mortality in non-ventilated patients. Immunosuppression increases the risk of mortality with progressively worsening oxygenation status, but only in the presence of mechanical ventilation. Further research into the impact of mechanical ventilation in immunosuppressed patients is required.

Many immune-based intestinal disorders, such as ulcerative colitis and Crohn's disease, as well as other illnesses, may have the intestines as an initial cause or aggravator in the development of diseases, even apparently not correlating directly to the intestine. Diabetes, obesity, multiple sclerosis, depression, and anxiety are examples of other illnesses discussed in the literature. In parallel, importance of the gut microbiota in intestinal homeostasis and immunologic conflict between tolerance towards commensal microorganisms and combat of pathogens is well known. Recent researches show that the immune system, when altered by the gut microbiota, influences the state in which these diseases are presented in the patient directly and indirectly. At the present moment, a considerable number of investigations about this subject have been performed and published. However, due to difficulties on correlating information, several speculations and hypotheses are generated. Thus, the present review aims at bringing together how these interactions work-gut microbiota, immune system, and their influence in the neuroimmune system.

Morea, Jessica M; Friend, Ronald; Bennett, Robert M

2008-12-01

Illness self-concept (ISC), or the extent to which individuals are consumed by their illness, was theoretically described and evaluated with the Illness Self-Concept Scale (ISCS), a new 23-item scale, to predict adjustment in fibromyalgia. To establish convergent and discriminant validity, illness self-concept was compared to self-esteem and optimism in predicting health status, illness intrusiveness, depression, and life satisfaction. The ISCS demonstrated good reliability (alpha = .94; test-retest r = .80) and was a strong predictor of outcomes, even after controlling for optimism or self-esteem. The ISCS predicted unique variance in health-related outcomes; optimism and self-esteem did not, providing construct validation. Illness self-concept may play a significant role in coping with fibromyalgia and may prove useful in the evaluation of other chronic illnesses. (c) 2008 Wiley Periodicals, Inc.

This slide presentation reviews a study that was conducted to ascertain if the immune system dysregulation, viral reactivation and stress from short duration space flight were a result of the stress of landing and readjustment to gravity. The objectives of the study were to replace several recent immune studies with one comprehensive study that will include in-flight sampling; address lack of in-flight data: (i.e., determine the in-flight status of immunity, physiological stress, viral immunity/reactivation); determine the clinical risk related to immune dysregulation for exploration class spaceflight; and determine the appropriate monitoring strategy for spaceflight-associated immune dysfunction, that could be used for the evaluation of countermeasures.

To determine the health status of the children for conditions associated with poverty. Cross sectional. Households in Chitungwiza, a dormitory town of Harare, Zimbabwe. 181 children less than five years of age in 1990 and 162 in 1993. Nutritional status and illness experienced by children. A total of 191 (90.0%) mothers breast fed for more than a year. Thirty two (24.2%) children more than six months old in 1990 and 24 (18.9%) in 1993 were offered less than three meals a day. Illnesses were most common (90.9%) in children aged six to 11 months old and decreased after this. Diarrhoea and coughs accounted for most of this excess (87.9%). Coughs alone affected 33.8% of children of all ages. Knowledge of making rehydration sugar/salt solution was wrong in 23.9% of mothers. Appropriate immunization was given to 85% of children in 1993. Twenty one (14.9%) children in 1990 and 15(12.2%) in 1993 were under 80% weight for age. Thirteen (8.7%) children in 1990 and 16 (10.8%) in 1993 were stunted. Breast feeding was generally satisfactory but the number of meals offered to a fifth of the children aged more than six months was inadequate. Instructions for making rehydration sugar/salt solution, on composition and quantity to be given should be made easily available so that the rate of mothers with wrong knowledge of making the sugar salt solution could be decreased. Children of age six to 11 months need to be kept warm to avoid coughs and need to be brought up in hygienic conditions to avoid diarrhoea.

Prisoners signify: a political discourse analysis of mental illness in a prison control unit.

Science.gov (United States)

Cloyes, Kristin Gates

2007-09-01

Increasingly, US prisoners diagnosed with mental illness are housed in control units, the most restrictive form of confinement in the US prison system. This situation has led to intense debate over the legal, ethical and clinical status of mental illness. This is a semiotic struggle with profound effects, yet most related work treats mental illness as a neutral, individual variable. Few analyses locate mental illness within a larger sociopolitical context. Fewer still focus on discursive practice. None critically analyze the accounts of control unit prisoners, who talk about extreme marginality and risk for victimization. This paper has two aims: (i) to develop a systematic method of analysis that accounts for signification as discourse-in-action; and (ii) to show how prisoners' signification of mental illness articulates agency through and against marginalizing discourse. Political discourse analysis demonstrates how control unit prisoners with psychiatric diagnoses signify mental illness, and articulate safer identifications in the process.

Full Text Available Abstract Background The quality of the relationship with the spouse/partner appears crucial among patients with multiple chronic conditions where illness management is complex and multifaceted. This study draws on data from the Quebec Health Survey (QHS to examine, among patients with one or more chronic conditions, the relation between marital status, the perceived conflict with the spouse/partner, and what the patients do to manage their illness as well as how they perceive their health. Methods Data from the QHS 1998 were used. The sample included 7547 coupled adults who had one or more chronic health problems lasting more than 6 months. Independent variables included marital status, perceived conflict with the spouse/partner, and the number of chronic conditions. Illness management was defined broadly as a measure of the patient's efforts at self-care and an illness status indicator, including visits to the generalist and the specialist, the use of telephone health line in the last 12 months, self-rated general health, mental health, and a measure of psychological distress. Linkages between the independent variables and illness management were assessed for males and females separately with logistic regressions, while accounting for the survey sampling design and household clustering. Results Female patients who did not live with their partner and had never been married were more likely to report a negative perception of their general health and a higher psychological distress than those who were married. Perceived conflict with the partner was linked to a negative perception of mental health and a higher psychological distress among both men and women. Compared to patients with only one chronic condition, males who reported more than one chronic condition were more likely to have consulted a generalist prior to the survey and used the telephone health line, whereas females were more likely to have consulted a specialist.

1983-01-01

The safety and efficacy of an attenuated canine parvovirus (A-CPV) vaccine was evaluated in both experimental and in field dogs. After parenteral vaccination, seronegative dogs developed hemagglutination-inhibition (HI) antibody titers as early as postvaccination (PV) day 2. Maximal titers occurred within 1 week. Immunity was associated with the persistence of HI antibody titers (titers greater than 80) that endured at least 2 years. Immune dogs challenged with virulent CPV did not shed virus in their feces. The A-CPV vaccine did not cause illness alone or in combination with living canine distemper (CD) and canine adenovirus type-2 (CAV-2) vaccines, nor did it interfere with the immune response to the other viruses. A high rate (greater than 98%) of immunity was engendered in seronegative pups. In contrast, maternal antibody interfered with the active immune response to the A-CPV. More than 95% of the dogs with HI titers less than 10 responded to the vaccine, but only 50% responded when titers were approximately 20. No animal with a titer greater than 80 at the time of vaccination became actively immunized. Susceptibility to virulent CPV during that period when maternal antibody no longer protects against infection, but still prevents active immunization, is the principal cause of vaccinal failure in breeding kennels where CPV is present. Reduction, but not complete elimination, of CPV disease in large breeding kennels occurred within 1-2 months of instituting an A-CPV vaccination program.

The stomach acts as a barrier to ingested microbes, thereby influencing the microbial ecology of the entire gastrointestinal (GI) tract. The stomach microbiota and the role of human host and environmental factors, such as health status or medications, in shaping its composition remain largely unknown. We sought to characterize the bacterial and fungal microbiota in the stomach fluid in order to gain insights into the role of the stomach in GI homeostasis. Gastric fluid was collected from 25 patients undergoing clinically indicated upper endoscopy. DNA isolates were used for PCR amplification of bacterial 16S ribosomal RNA (rRNA) genes and fungal internal transcribed spacers (ITS). RNA isolates were used for 16S rRNA cDNA generation and subsequent PCR amplification. While all stomach fluid samples are dominated by the phyla Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria and Fusobacteria (>99% of sequence reads), the transcriptionally active microbiota shows significant reduction in Actinobacteria (34%) and increase in Campylobacter (444%) (PpH >4 (70%; P<0.05). Immunosuppression correlates with decreased abundance of Prevotella (24%), Fusobacterium (2%) and Leptotrichia (6%) and increased abundance of Lactobacillus (3844%) (P<0.003). We have generated the first in-depth characterization of the human gastric fluid microbiota, using bacterial 16S rRNA gene and transcript, and fungal ITS amplicon sequencing and provide evidence for a significant impact of the host immune status on its composition with likely consequences for human health.

Exertional heat illness: emerging concepts and advances in prehospital care.

Pryor, Riana R; Roth, Ronald N; Suyama, Joe; Hostler, David

2015-06-01

Exertional heat illness is a classification of disease with clinical presentations that are not always diagnosed easily. Exertional heat stroke is a significant cause of death in competitive sports, and the increasing popularity of marathons races and ultra-endurance competitions will make treating many heat illnesses more common for Emergency Medical Services (EMS) providers. Although evidence is available primarily from case series and healthy volunteer studies, the consensus for treating exertional heat illness, coupled with altered mental status, is whole body rapid cooling. Cold or ice water immersion remains the most effective treatment to achieve this goal. External thermometry is unreliable in the context of heat stress and direct internal temperature measurement by rectal or esophageal probes must be used when diagnosing heat illness and during cooling. With rapid recognition and implementation of effective cooling, most patients suffering from exertional heat stroke will recover quickly and can be discharged home with instructions to rest and to avoid heat stress and exercise for a minimum of 48 hours; although, further research pertaining to return to activity is warranted.

Future oceanic warming and acidification alter immune response and disease status in a commercial shellfish species, Mytilus edulis L.

Directory of Open Access Journals (Sweden)

Clara L Mackenzie

Full Text Available Increases in atmospheric carbon dioxide are leading to physical changes in marine environments including parallel decreases in ocean pH and increases in seawater temperature. This study examined the impacts of a six month exposure to combined decreased pH and increased temperature on the immune response and disease status in the blue mussel, Mytilus edulis L. Results provide the first confirmation that exposure to future acidification and warming conditions via aquarium-based simulation may have parallel implications for bivalve health. Collectively, the data suggests that temperature more than pH may be the key driver affecting immune response in M. edulis. Data also suggests that both increases in temperature and/or lowered pH conditions may lead to changes in parasite abundance and diversity, pathological conditions, and bacterial incidence in M. edulis. These results have implications for future management of shellfish under a predicted climate change scenario and future sustainability of shellfisheries. Examination of the combined effects of two stressors over an extended exposure period provides key preliminary data and thus, this work represents a unique and vital contribution to current research efforts towards a collective understanding of expected near-future impacts of climate change on marine environments.

Despite the relentless efforts to reduce infant and child mortality with the introduction of the National Expanded Programmes on Immunization (EPI) in 1974, major disparities still exist in immunizations coverage across different population sub-groups. In Kenya, for instance, while the proportion of fully immunized children increased from 57% in 2003 to 77% in 2008-9 at national level and 73% in Nairobi, only 58% of children living in informal settlement areas are fully immunized. The study aims to determine the degree and determinants of immunization inequality among the urban poor of Nairobi. We used data from the Nairobi Cross-Sectional Slum Survey of 2012 and the health outcome was full immunization status among children aged 12-23 months. The wealth index was used as a measure of social economic position for inequality analysis. The potential determinants considered included sex of the child and mother's education, their occupation, age at birth of the child, and marital status. The concentration index (CI) was used to quantify the degree of inequality and decomposition approach to assess determinants of inequality in immunization. The CI for not fully immunized was -0.08 indicating that immunization inequality is mainly concentrated among children from poor families. Decomposition of the results suggests that 78% of this inequality is largely explained by the mother's level of education. There exists immunization inequality among urban poor children in Nairobi and efforts to reduce this inequality should aim at targeting mothers with low level of education during immunization campaigns.

The hospital as a work environment is particularly characterized by various risks for healthcare workers (HCWs). The main risk is represented by biological accidents, associated with the parenteral transmission of pathogens. Biological injuries can occur during the care service and the manipulation of biological fluids. Hepatitis B (and hepatitis D), hepatitis C and HIV are the most common infections transmitted by biological injuries. Physicians should acquire awareness of the risks associated with their professional activity during their training as medical residents (MRs). Some infectious diseases are preventable by vaccination and the "National Immunization Plan 2017-2019" (PNPV) recommends HCWs vaccination against hepatitis B, influenza, measles -mumps -rubella, chicken pox, and pertussis. Besides, not only HCWs' vaccination can prevent the disease in healthcare professionals, but it also may reduce the transmission to patients. Therefore, active immunization of HCWs by recommended vaccinations plays an important role to prevent disease cases, complications and death in patients. An increased awareness of risk behaviors is the first important point to address in order to reduce biological accidents and infectious diseases transmission, so as to reduce their frequency. Besides, HCWs' vaccination is useful to reinforce protection and to prevent the transmission of some infectious diseases in case of exposure. The aim of this five-year incidence study is to investigate the MRs' biological accidents characteristics and to analyze the MRs' immune status at the University of Ferrara in the period 2011-2015. Data on MRs' biological accidents and immune status at Azienda Ospedaliero-Universitaria of Ferrara in 2011-2015 were analyzed by Microsoft Excel 2007 Software. In this study, the percentage of MRs' biological injuries compared to the total number of MRs showed an annual variability, with a peak in 2011 (11.9%). During the analyzed period, there were 190

Full Text Available The objective of this study was to determine the effects of feeding protein-iron complex (PIC on productive performance and indicators of iron metabolism, hematology parameters, antioxidant and immune status during first 35 days of a calf’s life. Preparation of the complex involved enzymatic hydrolysis of milk casein (serine protease from Yarrowia lipolytica yeast. Iron chloride was then added to the hydrolyzate and lyophilizate. Calves were divided into treated groups: LFe (low iron dose 10 g/day calf of protein-iron complex, HFe (height iron dose 20 g/day calf, and control group. Dietary supplements containing the lower dose of concentrate had a significant positive effect on iron metabolism, while the higher dose of concentrate resulted in increase of total iron binding capacity (TIBC, saturation of transferrin and decrease of and unsaturated iron binding capacity (UIBC, which suggest iron overload. Additionally, treatment with the lower dose of iron remarkably increased the antioxidant parameters, mainly total antioxidant (TAS and glutathione peroxidase activity (GPx. Higher doses of PIC were related to lower total antioxidant status. IgG, IgM, insulin, glucose, TNFα and IGF-1 concentration did not change significantly in either group after supplementation. In practice, the use of protein-iron complex concentrate requires taking into account the iron content in milk replacers and other feedstuffs.

Military recruits are susceptible to respiratory pathogens because of increased antibiotic resistance and the lack of an effective vaccine. The goal of the current study was to determine the immunological status of the Bordetella pertussis among conscripts in Iranian military garrisons. The study population consisted of 424 conscripts aged 18 to 21 years who enrolled for military service. They were selected using cluster stratified sampling from all military garrisons in Tehra, Iran. To determine the seroprevalence of infection, blood specimens from all recruits were collected and stored at - 20 °C until assayed. All serum samples were screened for immunoglobulin G (IgG) antibodies against Bordetella pertussis toxin (PT) and by using enzyme-linked immunosorbent assay (ELISA). The overall prevalence of B. pertussis seropositivity in military recruits was 60.6. Only 55.0% of the recruits had low awareness about the record of vaccination against B. pertussis during childhood. Among 424 studied individuals, 48 recruits (11.3%) had a positive history of whooping cough; prevalence of seropositivity in these recruits was 70.0%. Among these subjects, 61.7% were referred to a physician for treatment and only 39.6% of them were administered anti-pertussis therapy. Our study showed that military conscripts in Tehran garrisons were not serologically immune to pertussis and also confirmed the low awareness about vaccination and medical history related to pertussis infection in this high-risk subgroup of the Iranian population. Routine acellular booster vaccination, particularly before 18 years of age, is recommended.

There is a growing interest in understanding the connection between mental illness (MI) and the onset of new physical illnesses among previously physically healthy individuals. Yet the role of gender is often forgotten in research focused on comorbidity of health problems. The objective of this study was to examine gender differences in the onset of physical illness in a cohort of respondents who met criteria for MI compared with a control cohort without mental health problems. This cohort study, conducted in Ontario, Canada, used a unique linked dataset with information from the 2000-2001 Canadian Community Health Survey and medical records (n=15,902). We used adjusted Cox proportional survival analysis to examine risk of onset of four physical health problems (chronic obstructive pulmonary disorder, asthma, hypertension and diabetes) for those with and without baseline MI across a 10-year period (2002-2011) among respondents aged 18-74 years. We controlled for socioeconomic and health indicators associated with health. The incidence of physical illness in the MI cohort was 28.5% among women and 29.9% among men (p=0.85) relative to controls (23.8% and 24%, respectively; p=0.48). Women in the MI cohort developed secondary physical health problems a year earlier than their male counterparts (p=0.002). Findings from the Cox proportional survival regression showed that women were at 14% reduced risk of developing physical illness, meaning that men were more disadvantaged (HR=0.89, CI 0.80 to 0.98). Those in the MI cohort were at 10 times greater risk of developing a secondary physical illness over the 10-year period (HR=1.10, CI 0.98 to 1.21). There was no significant interaction between gender and MI cohort (HR=1.05, CI 0.85 to 1.27). Policy and clinical practice have to be sensitive to these complex-needs patients. Gender-specific treatment and prevention practices can be developed to target those at higher risk of multiple health conditions.

Full Text Available Subject. The relationship between lipid metabolism and immune reactivity in the dynamics of long-term exposure to coal-rock dust (CRD on the body. Objective. In the experiment to examine the impact of the changes in the lipid profile on immune status under the conditions of long-term exposure to CRD on the body. Methods. The experiments were carried out on 110 white male rats weighing 200-250 g. The inhalation method was used for modeling that best fits the conditions of coal-mine production. Animals were divided into 2 groups: the control (n = 30; the experiment (n = 80, that are the rats who inhaled CRD with a particle size of up to 5 microns in an average concentration of 50 mg/m3 for 4 hours daily for 12 weeks. Main results. Early terms of the CRD impact are characterized by the activation of the immune system against the background of metabolic shifts as well as by morphological changes of the immune nature in the bronchopulmonary system and liver of the rats that can be regarded as compensatory-adaptive. Prolonged exposure to the dust factor leads to an increase in dyslipidemia, which contributes to the development of immune imbalance as well as morphological changes that are indicative of the chronic inflammation and disturbance of compensatory mechanisms. Field of application. The results of the conducted experimental studies broaden the fundamental ideas about the mechanisms of immune body defense. The detection of pathogenetic mechanisms underlying the formation and course of occupational diseases allows assessing the functional state of the organism at the stage of pre-existing disease, revealing the initial signs of developing pathology and determining the ways of their correction. Conclusions. CRD intake is characterized by the development of metabolic changes, which are closely related to immune reactivity. An integrated approach to the study of occupational and industrially-caused pathology makes it possible to assess the

Cirrhotic patients often develop severe complications requiring ICU admission. Grade III-IV hepatic encephalopathy, septic shock, acute-on-chronic liver failure and variceal bleeding are clinical decompensations that need a specific therapeutic approach in cirrhosis. The increased effectiveness of the treatments currently used in this setting and the spread of liver transplantation programs have substantially improved the prognosis of critically ill cirrhotic patients, which has facilitated their admission to critical care units. However, gastroenterologists and intensivists have limited knowledge of the pathogenesis, diagnosis and treatment of these complications and of the prognostic evaluation of critically ill cirrhotic patients. Cirrhotic patients present alterations in systemic and splanchnic hemodynamics, coagulation and immune dysfunction what further increase the complexity of the treatment, the risk of developing new complications and mortality in comparison with the general population. These differential characteristics have important diagnostic and therapeutic implications that must be known by general intensivists. In this context, the Catalan Society of Gastroenterology and Hepatology requested a group of experts to draft a position paper on the assessment and treatment of critically ill cirrhotic patients. This article describes the recommendations agreed upon at the consensus meetings and their main conclusions. Copyright © 2015 Elsevier España, S.L.U. y AEEH y AEG. All rights reserved.

A minimal model for multiple epidemics and immunity spreading.

Pathogens and parasites are ubiquitous in the living world, being limited only by availability of suitable hosts. The ability to transmit a particular disease depends on competing infections as well as on the status of host immunity. Multiple diseases compete for the same resource and their fate is coupled to each other. Such couplings have many facets, for example cross-immunization between related influenza strains, mutual inhibition by killing the host, or possible even a mutual catalytic effect if host immunity is impaired. We here introduce a minimal model for an unlimited number of unrelated pathogens whose interaction is simplified to simple mutual exclusion. The model incorporates an ongoing development of host immunity to past diseases, while leaving the system open for emergence of new diseases. The model exhibits a rich dynamical behavior with interacting infection waves, leaving broad trails of immunization in the host population. This obtained immunization pattern depends only on the system size and on the mutation rate that initiates new diseases.

T cell immunity to influenza in older adults: A pathophysiological framework for development of more effective vaccines

2016-02-01

Full Text Available One of the most profound public health consequences of immune senescence is reflected in an increased susceptibility to influenza and other acute respiratory illnesses, as well as a loss of influenza vaccine effectiveness in older people. Common medical conditions and mental and psychosocial health issues as well as degree of frailty and functional dependence accelerate changes associated with immune senescence. All contribute to the increased risk for complications of influenza infection including pneumonias, heart diseases and strokes that lead to hospitalization, disability and death in the over 65 population. Changes in mucosal barrier mechanisms and both innate and adaptive immune functions converge in the reduced response to influenza infection, and lead to a loss of antibody-mediated protection against influenza with age. The interactions of immune senescence and reduced adaptive immune responses, persistent cytomegalovirus infection, inflammaging (chronic elevation of inflammatory cytokines, and dysregulated cytokine production, pose major challenges to the development of vaccines designed to improve T-cell mediated immunity. In older adults, the goal of vaccination is more realistically targeted to providing clinical protection against disease rather than to inducing sterilizing immunity to infection. Standard assays of antibody titres correlate with protection against influenza illness but do not detect important changes in cellular immune mechanisms that correlate with vaccine-mediated protection against influenza in older people. This article will discuss: i the burden of influenza in older adults and how this relates to changes in T cell function, ii age-related changes in different T cell subsets and immunologic targets for improved influenza vaccine efficacy in older, and iii the development of correlates of clinical protection against influenza disease to expedite the process of new vaccine development for the 65 and older

The stigma surrounding mental ill-health is an important issue that affects likelihood of diagnosis and uptake of services, as those affected may work to avoid exposure, judgment, or any perceived loss in status associated with their mental ill-health. In this study, we drew upon social identity theory to examine how social group membership might influence the stigma surrounding mental ill-health. Participants from two urban centers in Ireland (N = 626) completed a survey measuring stigma of mental health, perceived social support as well as identification with two different social groups (community and religion). Mediation analysis showed that subjective identification with religious and community groups led to greater perceived social support and consequently lower perceived stigma of mental ill-health. Furthermore, findings indicated that high identification with more than one social group can lead to enhanced social resources, and that identification with a religious group was associated with greater community identification. This study thus extends the evidence base of group identification by demonstrating its relationship with stigma of mental ill-health, while also reinforcing how multiple identities can interact to enhance social resources crucial for well-being. © Society for Community Research and Action 2017.

Achieving adequate response rates from family members of critically ill patients can be challenging, especially when assessing psychological symptoms. To identify factors associated with completion of surveys about psychological symptoms among family members of critically ill patients. Using data from a randomized trial of an intervention to improve communication between clinicians and families of critically ill patients, we examined patient-level and family-level predictors of the return of usable surveys at baseline, three months, and six months (n = 181, 171, and 155, respectively). Family-level predictors included baseline symptoms of psychological distress, decisional independence preference, and attachment style. We hypothesized that family with fewer symptoms of psychological distress, a preference for less decisional independence, and secure attachment style would be more likely to return questionnaires. We identified several predictors of the return of usable questionnaires. Better self-assessed family member health status was associated with a higher likelihood and stronger agreement with a support-seeking attachment style with a lower likelihood, of obtaining usable baseline surveys. At three months, family-level predictors of return of usable surveys included having usable baseline surveys, status as the patient's legal next of kin, and stronger agreement with a secure attachment style. The only predictor of receipt of surveys at six months was the presence of usable surveys at three months. We identified several predictors of the receipt of surveys assessing psychological symptoms in family of critically ill patients, including family member health status and attachment style. Using these characteristics to inform follow-up mailings and reminders may enhance response rates. Copyright © 2017 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.

Full Text Available Abstract Introduction This review of 25 consecutive patients with Morgellons disease (MD was undertaken for two primary and extremely fundamental reasons. For semantic accuracy, there is only one "proven" MD patient: the child first given that label. The remainder of inclusive individuals adopted the label based on related descriptions from 1544 through 1884, an internet description quoted from Sir Thomas Browne (1674, or was given the label by practitioners using similar sources. Until now, there has been no formal characterization of MD from detailed examination of all body systems. Our second purpose was to differentiate MD from Delusions of Parasitosis (DP, another "informal" label that fit most of our MD patients. How we defined and how we treated these patients depended literally on factual data that would determine outcome. How they were labeled in one sense was irrelevant, except for the confusing conflict rampant in the medical community, possibly significantly skewing treatment outcomes. Case presentation Clinical information was collected from 25 of 30 consecutive self-defined patients with Morgellons disease consisting of laboratory data, medical history and physical examination findings. Abnormalities were quantified and grouped by system, then compared and summarized, but the numbers were too small for more complex mathematical analysis. The quantification of physical and laboratory abnormalities allowed at least the creation of a practical clinical boundary, separating probable Morgellons from non-Morgellons patients. All the 25 patients studied meet the most commonly used DP definitions. Conclusions These data suggest Morgellons disease can be characterized as a physical human illness with an often-related delusional component in adults. All medical histories support that behavioral aberrancies onset only after physical symptoms. The identified abnormalities include both immune deficiency and chronic inflammatory markers that

The individual placement and supported (IPS) model of supported employment is the most empirically validated model of vocational rehabilitation for persons with schizophrenia or another serious mental illness. Over 18 randomized controlled trials have been conducted throughout the world demonstrating the effectiveness of supported employment at improving competitive work compared to other vocational programs: IPS supported employment is defined by the following principles: 1) inclusion of all clients who want to work; 2) integration of vocational and clinical services; 3) focus on competitive employment; 4) rapid job search and no required prevocational skills training; 5) job development by the employment specialist; 6) attention to client preferences about desired work and disclosure of mental illness to prospective employers; 7) benefits counseling; and 8) follow-along supports after a job is obtained. Supported employment has been successfully implemented in a wide range of cultural and clinical populations, although challenges to implementation are also encountered. Common challenges are related to problems such as the failure to access technical assistance, system issues, negative beliefs and attitudes of providers, funding restrictions, and poor leadership. These challenges can be overcome by tapping expertise in IPS supported employment, including standardized and tested models of training and consultation. Efforts are underway to increase the efficiency of training methods for supported employment and the overall program, and to improve its effectiveness for those clients who do not benefit. Progress in IPS supported employment offers people with a serious mental illness realistic hope for achieving their work goals, and taking greater control over their lives. Copyright © 2014.

2014-11-01

Many OECD countries have implemented anti-discrimination laws in recent decades. However, according to the annual report published in 2010 by the French High Authority for the Fight against Discrimination and for Equality, the second most commonly cited factor in discrimination claims since 2005 is a handicap or health status. The aim of this research is to estimate the level of unexplained components in the wage gap that can be attributed to wage discrimination based on health status in France in 2010 utilizing data from the Health, Healthcare and Insurance survey among 1594 individuals. Three health indicators are used: self-perceived health status, activity limitations and long-term chronic illness. To measure the wage gap according to an individual's health status, the analysis considers the endogenous selection of health status and unobserved differences in productivity. The results demonstrate that wage discrimination is experienced by individuals in poor health regardless of the health indicator utilized. The hourly wage rate among individuals with poor self-assessed health status is on average 14.2% lower than among individuals with good self-assessed health status. However, for individuals suffering from a long-term chronic illness or an activity limitation, the gap is 6.3% and 4.5%, respectively. The decomposition performed on wage differences according to health status by correcting for health status selection bias and controlling for unobserved differences in productivity indicates that the 'unexplained component' that can be attributed to wage discrimination is equal to 50%.

Full Text Available Background. The aim of the study was to assess the relationships among serum neopterin (NPT, β2-microglobulin (β2-M levels, clinical status, and endomyocardial biopsy results of dilated cardiomyopathy patients (DCM. Methods. Serum NPT and β-2 M were determined in 172 nonischaemic DCM patients who underwent right ventricular endomyocardial biopsy and 30 healthy subjects (ELISA test. The cryostat biopsy specimens were assessed using histology, immunohistology, and immunochemistry methods (HLA ABC, HLA DR expression, CD3 + lymphocytes, and macrophages counts. Results. The strong increase of HLA ABC or HLA DR expression was detected in 27.2% patients—group A—being low in 72.8% patients—group B. Neopterin level was increased in patients in group A compared to healthy controls 8.11 (4.50–12.57 versus 4.99 (2.66–8.28 nmol/L (P<0.05. β-2 microglobulin level was higher in DCM groups A (2.60 (1.71–3.58 and B (2.52 (1.51–3.72 than in the control group 1.75 (1.28–1.96 mg/L, P<0.001. Neopterin correlated positively with the number of macrophages in biopsy specimens (P<0.05 acute phase proteins: C-reactive proteins (P<0.05; fibrinogen (P<0.01; and NYHA functional class (P<0.05 and negatively with left ventricular ejection fraction (P<0.05. Conclusions. Neopterin but not β-2 microglobulin concentration reflected immune response in biopsy specimens. Neopterin correlated with acute phase proteins and stage of heart failure and may indicate a general immune and inflammatory activation in heart failure.

Achieving Remission in Gulf War Illness: A Simulation-Based Approach to Treatment Design.

Directory of Open Access Journals (Sweden)

Travis J A Craddock

Full Text Available Gulf War Illness (GWI is a chronic multi-symptom disorder affecting up to one-third of the 700,000 returning veterans of the 1991 Persian Gulf War and for which there is no known cure. GWI symptoms span several of the body's principal regulatory systems and include debilitating fatigue, severe musculoskeletal pain, cognitive and neurological problems. Using computational models, our group reported previously that GWI might be perpetuated at least in part by natural homeostatic regulation of the neuroendocrine-immune network. In this work, we attempt to harness these regulatory dynamics to identify treatment courses that might produce lasting remission. Towards this we apply a combinatorial optimization scheme to the Monte Carlo simulation of a discrete ternary logic model that represents combined hypothalamic-pituitary-adrenal (HPA, gonadal (HPG, and immune system regulation in males. In this work we found that no single intervention target allowed a robust return to normal homeostatic control. All combined interventions leading to a predicted remission involved an initial inhibition of Th1 inflammatory cytokines (Th1Cyt followed by a subsequent inhibition of glucocorticoid receptor function (GR. These first two intervention events alone ended in stable and lasting return to the normal regulatory control in 40% of the simulated cases. Applying a second cycle of this combined treatment improved this predicted remission rate to 2 out of 3 simulated subjects (63%. These results suggest that in a complex illness such as GWI, a multi-tiered intervention strategy that formally accounts for regulatory dynamics may be required to reset neuroendocrine-immune homeostasis and support extended remission.

Critics of "scorecard medicine" often highlight the incompleteness of risk-adjustment methods used when accounting for baseline patient differences. Although socioeconomic status is a highly important determinant of adverse outcome for patients admitted to the hospital with acute myocardial infarction, it has not been used in most risk-adjustment models for cardiovascular report cards. To determine the incremental impact of socioeconomic status adjustments on age, sex, and illness severity for hospital-specific 30-day mortality rates after acute myocardial infarction. The authors compared the absolute and relative hospital-specific 30-day acute myocardial infarction mortality rates in 169 hospitals throughout Ontario between April 1, 1994 and March 31, 1997. Patient socioeconomic status was characterized by median neighborhood income using postal codes and 1996 Canadian census data. They examined two risk-adjustment models: the first adjusted for age, sex, and illness severity (standard), whereas the second adjusted for age, sex, illness severity, and median neighborhood income level (socioeconomic status). There was an extremely strong correlation between 'standard' and 'socioeconomic status' risk-adjusted mortality rates (r = 0.99). Absolute differences in 30-day risk-adjusted mortality rates between the socioeconomic status and standard risk-adjustment models were small (median, 0.1%; 25th-75th percentile, 0.1-0.2). The agreement in the quintile rankings of hospitals between the socioeconomic status and standard risk-adjustment models was high (weighted kappa = 0.93). Despite its importance as a determinant of patient outcomes, the effect of socioeconomic status on hospital-specific mortality rates over and above standard risk-adjustment methods for acute myocardial infarction hospital profiling in Ontario was negligible.

A specialized antigenpresenting cell present at mucosal surfaces, the dendritic cell (DC......), plays a crucial role in shaping the nature of the adaptive/memorybased immune response after encountering inflammatory compounds. In the gut, the DC is continuously exposed to microbial and dietary components that are recognized by its innate pattern recognition receptors, and the phenotype developed...... in the DC during activation is of profound importance for the state of immune response and thereby also affects the inflammatory and metabolic status in tissues. We have shown that specific fermentation products from gut bacteria have distinct immunoregulatory effects that effectively inhibit...

This cross-sectional seroprevalence study was carried out in 2007 to estimate the immunological status associated with poliomyelitis among fertile women , according to demographic changes. We consecutively enrolled 493 healthy mothers at the time of delivery in order to assess immunity against poliomyelitis by a neutralisation inhibition test. Despite the lack of seronegative subjects, our investigation showed low GMTs, which confirmed a reduction in the "booster effect". The GMTs against poliovirus 1, poliovirus 2 and poliovirus 3 were 25.20, 14.79 and 8.80, respectively. The data that emerged from our survey showed that GMTs have decreased significantly since 1983 and reached low-to-medium values over the past 25 years. The serum prevalence studies, together with the vaccination coverage estimates, are useful and are strongly recommended in order to highlight and identify the possible scenarios in which susceptible subject groups may be present simultaneously as well the possibility of the reintroduction of wild virus in an area that was previously free of polio.

Impact of supplementation with amino acids or their metabolites on muscle wasting in patients with critical illness or other muscle wasting illness: a systematic review.

Muscle wasting during critical illness impairs recovery. Dietary strategies to minimise wasting include nutritional supplements, particularly essential amino acids. We reviewed the evidence on enteral supplementation with amino acids or their metabolites in the critically ill and in muscle wasting illness with similarities to critical illness, aiming to assess whether this intervention could limit muscle wasting in vulnerable patient groups. Citation databases, including MEDLINE, Web of Knowledge, EMBASE, the meta-register of controlled trials and the Cochrane Collaboration library, were searched for articles from 1950 to 2013. Search terms included 'critical illness', 'muscle wasting', 'amino acid supplementation', 'chronic obstructive pulmonary disease', 'chronic heart failure', 'sarcopenia' and 'disuse atrophy'. Reviews, observational studies, sport nutrition, intravenous supplementation and studies in children were excluded. One hundred and eighty studies were assessed for eligibility and 158 were excluded. Twenty-two studies were graded according to standardised criteria using the GRADE methodology: four in critical care populations, and 18 from other clinically relevant areas. Methodologies, interventions and outcome measures used were highly heterogeneous and meta-analysis was not appropriate. Methodology and quality of studies were too varied to draw any firm conclusion. Dietary manipulation with leucine enriched essential amino acids (EAA), β-hydroxy-β-methylbutyrate and creatine warrant further investigation in critical care; EAA has demonstrated improvements in body composition and nutritional status in other groups with muscle wasting illness. High-quality research is required in critical care before treatment recommendations can be made. © 2014 The British Dietetic Association Ltd.

Obesity impacts the physical and psychological health of children and adolescents, and is a risk factor for development of episodic and chronic illness. Rural Mexican-American adolescents are at risk for obesity and associated chronic illnesses.The study used a retrospective chart review of data collected routinely in a rural health clinic setting from 1 January 2005 to 31 December 2010 to assess incidence of overweight/obesity status and episodic or chronic illness among Mexican-American adolescents aged 12-18 years. Analyses included body mass index, age, gender, and episodic or chronic illness diagnoses. Two hundred twelve charts were audited; women (n = 114, 53.8%), men (n = 98 46.2%); normal (n = 105, 49.5%), overweight/obese (n = 107, 50.5%). There were more female normal (n = 61, 53.5%) vs. overweight/obese (n = 53, 46.5%). More male overweight/obese (n = 54, 55.1%) than normal weight (n = 44, 44.9%). Age at first documented overweight/obesity status occurred in early adolescence (median = 13 years, mode = 12 years). Chronic illness incidence was higher among men than women, and overweight/obese vs. normal weight adolescents and in sub-categorizations by weight and specific illness. Incidence of episodic illness was higher among women than men, with variation by weight and specific illness. Disproportionately high incidence of episodic or chronic illness and overweight/obesity identified among rural Mexican-American adolescents compels intervention modification to improve effectiveness. © 2014 Wiley Publishing Asia Pty Ltd.

What is a mental illness? Public views and their effects on attitudes and disclosure.

Science.gov (United States)

Rüsch, Nicolas; Evans-Lacko, Sara; Thornicroft, Graham

2012-07-01

'Mental illness' is a common label. However, the general public may or may not consider various conditions, ranging from major psychiatric disorders to stress, as mental illnesses. It is unclear how such public views affect attitudes towards people with mental illness and reactions to one's own potential mental illness, e.g. in terms of help-seeking or disclosure. In representative English population surveys the classification of six conditions (schizophrenia, bipolar disorder, depression, drug addiction, stress, grief) as a mental illness was assessed as well as attitudes towards, and contact with, people with mental illness, intentions to disclose a mental illness and to seek treatment. A factor analysis of how strongly respondents perceived the six conditions as a mental illness yielded two factors: (i) major psychiatric disorders and (ii) stress- and behaviour-related conditions including drug addiction. In regression analyses, higher scores on the first, but not the second, factor predicted less perceived responsibility of people with mental illness for their actions, and more support for a neurobiological illness model and help-seeking. Classifying stress-related/behaviour-related conditions as mental illnesses, as well as not referring to major psychiatric disorders as mental illnesses, was associated with more negative attitudes and increased social distance, but also with stronger intentions to disclose a mental illness to an employer. Negative attitudes and social distance were also related to ethnic minority status and lower social grade. Referring to major psychiatric disorders as mental illnesses may reflect higher mental health literacy, better attitudes towards people with mental illness and help-seeking. A broader concept of mental illness could, although increasing negative attitudes, facilitate disclosure in the workplace. Public views on what is a mental illness may have context-dependent effects and should be taken into account in anti

Knowledge of maternal malnutrition of ruminants and effects on development of the immune system of their offspring is lacking. A study was conducted to investigate the effects of maternal protein or energy restriction during late gestation on immune status of their offspring at different ages. Sixty-three pregnant goats (local breed, Liuyang black goat, 22.2 ± 1.5 kg at d 90 of gestation) were fed control (CON, ME = 9.34 MJ/kg and CP = 12.5%, DM basis), 40% protein restricted (PR), or 40% energy restricted (ER) diets from d 91 of gestation to parturition, after which all animals received an adequate diet for nutritional recovery. Plasma concentrations of complement components (C3, C4), C-reactive protein (CRP) and immunoglobulins (IgG and IgM), jejunum cytokines (IL-2, IL-6, and IL-10) expression levels and morphology in the offspring were measured. Additionally, plasma concentration of complement and IL-6, and cytokines expression levels in gastrointestinal tract obtained at 6 wk from young goats were assessed under saline or lipopolysaccharide (LPS) challenging conditions. Maternal PR or ER decreased (P 0.05) plasma CRP concentration. The IL-10 mRNA expression of jejunum from PR kids was also less (P 0.05) in any plasma or tissue immune parameters among the 3 treatments. However, when given a LPS challenge, ER and PR kids had greater (P = 0.02) IL-6 concentration compared with CON kids. Our results suggest that both PR and ER during late gestation induced short-term as well as long-lasting alterations on immune responses in their offspring, which may make the animals more susceptible to a bacterial pathogen challenge. The present findings expand the existing knowledge in immunological mechanisms responsible for the development of disease in later life.

This study examined the loss of productivity and health risk status associated with employees who provide care for an ill dependent. A total of 16,651 employees (23% response rate) of a major financial services company completed a confidential Health Risk Appraisal (HRA) that included an eight-item version of the Work Limitations Questionnaire and a self-report of time missed from work during the previous 2 weeks to care for an ill dependent. A total of 10.6% of the respondents reported an average of 7.7 hours absent from work during the previous 2-week period to provide care for an ill dependent. Caregiving also was associated with a significant increase in the number of health risks for the employee. As the demand for caregiving time increased, caregivers reported a significant increase in work limitations. Caregiving for an ill dependent is associated with increased absenteeism and significant work limitations while on the job. Programs and work organization that helps employees balance their caregiving responsibilities for ill dependents may have a positive effect on health and productivity.

Background Public attitudes to mental illness could influence how the public interact with, provide opportunities for, and help people with mental illness. Aims This study aims to explore the underlying factors of the Attitudes to Mental Illness questionnaire among the general population in Singapore and the socio-demographic correlates of each factor. Methods From March 2014 to April 2015, a nation-wide cross-sectional survey on mental health literacy with 3,006 participants was conducted in Singapore. Results Factor analysis revealed a 4-factor structure for the Attitudes to Mental Illness questionnaire among the Singapore general population, namely social distancing, tolerance/support for community care, social restrictiveness, and prejudice and misconception. Older age, male gender, lower education and socio-economic status were associated with more negative attitudes towards the mentally ill. Chinese showed more negative attitudes than Indians and Malays (except for prejudice and misconception). Conclusions There is a need for culture-specific interventions, and the associated factors identified in this study should be considered for future attitude campaigns. PMID:27893796

HIV-positive patient with herpes zoster: a manifestation of the immune reconstitution inflammatory syndrome.

Lutwak, Nancy; Dill, Curt

2012-01-01

Herpes zoster is a common illness that can lead to serious morbidity. There is now evidence that HIV-infected patients who have been treated with antiretroviral therapy are at greater risk of developing herpes zoster not when they are severely immunocompromised but, paradoxically, when their immune system is recovering. This is a manifestation of the immune reconstitution inflammatory syndrome. The objectives of this report are to (1) inform health care providers that HIV-infected patients may develop multiple infectious, autoimmune, and oncological manifestations after treatment with antiretroviral medication, as they have immune system reconstitution, and (2) discuss herpes zoster, one of the possible manifestations. The patient is a 68-year-old HIV-positive man who presented with herpes zoster after being treated with highly active antiretroviral therapy (HAART) when his immune system was recovering, not when he was most immunosuppressed. Emergency department physicians should be aware that HIV-infected patients treated with HAART may have clinical deterioration despite immune system strengthening. This immune reconstitution inflammatory syndrome can present with infectious, autoimmune, or oncological manifestations. Our case patient, an HIV-positive man with immune system recovery after treatment with HAART, presented with an infectious manifestation, herpes zoster.

Inadequate self-management of chronic medical conditions like Type 2 diabetes may play a role in the poor health status of individuals with serious mental illnesses. We compared adherence to hypoglycemic medications and blood glucose control between 44 diabetes patients with a serious mental illness and 30 patients without a psychiatric illness. The two groups did not differ in their ability to manage a complex medication regimen as assessed by a performance-based measure of medication management capacity. However, significantly fewer patients with a mental illness self-reported nonadherence to their hypoglycemic regimens compared to those without a mental illness. Although individuals with mental illnesses also had better control of blood glucose, this metabolic parameter was not correlated with adherence to hypoglycemic medications in either patient group. The experience of managing a chronic mental illness may confer advantages to individuals with serious mental illnesses in the self-care of co-occurring medical conditions like Type 2 diabetes.

Full Text Available Background Immunization is a proven cost effective intervention to reduce the child mortality & morbidity. As per DLHS-3(2007-08 only 30.3% of children are fully immunized in Uttar Pradesh. A new district, Kanshi Ram Nagar was created on 15 April 2008 within Etah district. Objective To assess the primary immunization status & dropout rate. To find out reasons for immunization default. To study the difference, if any between high risk & low risk block. Material & methods A cross sectional, observational study was undertaken in two blocks (Patiyali and Amanpur of Kanshi Ram Nagar District by interviewing 210 respondent mothers in each block, by using ‘30’ cluster sampling technique with help of predesigned, pretested schedule. Result: The percentages of fully immunized children were 50% in Patiyali & 44.08% in Amanpur block. ANM & ASHA were observed as main informer to the community. Immunization status was poor in Muslims and in female children. The highest covered antigen found was BCG and lowest was DPT-3 in both the blocks. The overall dropout rate was 36.52% for Patiyali & 32.96 % for Amanpur block. The main reasons for dropout identified were, non-cooperation of health workers and community were not aware about the need of Immunization in both the blocks. However the differential findings in among the blocks were statistically not significant. Conclusion However lesser number of children were left untouched for immunization services but the percentage of incomplete immunization was found high due to poor cooperation of health worker and unawareness about need of immunization in community

[Problems and strategies in the treatment of mental disorders in elderly patients with physical illness].

Wada, H

There is a high prevalence of mental disorders in the community population of older adults, especially in medical treatment facilities. Therefore, clinicians who treat geriatric patients cannot neglect the psychiatric vulnerability of the elderly population. The fragility of psychological functioning of the elderly is caused not only by psychological contributors, such as various kinds of experiences of loss, but also by biological factors such as decreases in neurotransmitters and in the number of neurons. Another point geriatric clinicians should pay attention to is the powerful mind-body connection in the elderly. Recent psychoneuroimmunological research demonstrates that depression or other types of emotional stress damages the immune system, which can induce some physical diseases. This is especially true for the elderly, who have weakened cell-mediated immune function and are more susceptible to influence by the damaged immune function caused by such psychiatric dysfunction. Also, depression in the elderly can often lead to malnutrition or dehydration, which can induce various kinds of physical illness. On the other hand, physical illness in the elderly can induce depression, because of the psychological vulnerability of the elderly. Due to the strong mind-body connection in the elderly, the availability of psychiatric care is essential. When providing psychiatric care for the elderly, the clinician should attend to all symptoms, not minimizing the importance of biological treatment, while also trying to support the elderly patients psychologically through acceptance of their need for interdependency and respect for their narcissism.

Seasonal influenza vaccine and protection against pandemic (H1N1 2009-associated illness among US military personnel.

Matthew C Johns

Full Text Available INTRODUCTION: A novel A/H1N1 virus is the cause of the present influenza pandemic; vaccination is a key countermeasure, however, few data assessing prior seasonal vaccine effectiveness (VE against the pandemic strain of H1N1 (pH1N1 virus are available. MATERIALS AND METHODS: Surveillance of influenza-related medical encounter data of active duty military service members stationed in the United States during the period of April-October 2009 with comparison of pH1N1-confirmed cases and location and date-matched controls. Crude odds ratios (OR and VE estimates for immunized versus non-immunized were calculated as well as adjusted OR (AOR controlling for sex, age group, and history of prior influenza vaccination. Separate stratified VE analyses by vaccine type (trivalent inactivated [TIV] or live attenuated [LAIV], age groups and hospitalization status were also performed. For the period of April 20 to October 15, 2009, a total of 1,205 cases of pH1N1-confirmed cases were reported, 966 (80% among males and over one-half (58% under 25 years of age. Overall VE for service members was found to be 45% (95% CI, 33 to 55%. Immunization with prior season's TIV (VE = 44%, 95% CI, 32 to 54% as well as LAIV (VE = 24%, 95% CI, 6 to 38% were both found to be associated with protection. Of significance, VE against a severe disease outcome was higher (VE = 62%, 95% CI, 14 to 84% than against milder outcomes (VE = 42%, 95% CI, 29 to 53%. CONCLUSION: A moderate association with protection against clinically apparent, laboratory-confirmed Pandemic (H1N1 2009-associated illness was found for immunization with either TIV or LAIV 2008-09 seasonal influenza vaccines. This association with protection was found to be especially apparent for severe disease as compared to milder outcome, as well as in the youngest and older populations. Prior vaccination with seasonal influenza vaccines in 2004-08 was also independently associated with protection.

Metallothioneins: Emerging Modulators in Immunity and Infection

Kavitha Subramanian Vignesh

2017-10-01

Full Text Available Metallothioneins (MTs are a family of metal-binding proteins virtually expressed in all organisms including prokaryotes, lower eukaryotes, invertebrates and mammals. These proteins regulate homeostasis of zinc (Zn and copper (Cu, mitigate heavy metal poisoning, and alleviate superoxide stress. In recent years, MTs have emerged as an important, yet largely underappreciated, component of the immune system. Innate and adaptive immune cells regulate MTs in response to stress stimuli, cytokine signals and microbial challenge. Modulation of MTs in these cells in turn regulates metal ion release, transport and distribution, cellular redox status, enzyme function and cell signaling. While it is well established that the host strictly regulates availability of metal ions during microbial pathogenesis, we are only recently beginning to unravel the interplay between metal-regulatory pathways and immunological defenses. In this perspective, investigation of mechanisms that leverage the potential of MTs to orchestrate inflammatory responses and antimicrobial defenses has gained momentum. The purpose of this review, therefore, is to illumine the role of MTs in immune regulation. We discuss the mechanisms of MT induction and signaling in immune cells and explore the therapeutic potential of the MT-Zn axis in bolstering immune defenses against pathogens.

A minimal model for multiple epidemics and immunity spreading.

Directory of Open Access Journals (Sweden)

Kim Sneppen

Full Text Available Pathogens and parasites are ubiquitous in the living world, being limited only by availability of suitable hosts. The ability to transmit a particular disease depends on competing infections as well as on the status of host immunity. Multiple diseases compete for the same resource and their fate is coupled to each other. Such couplings have many facets, for example cross-immunization between related influenza strains, mutual inhibition by killing the host, or possible even a mutual catalytic effect if host immunity is impaired. We here introduce a minimal model for an unlimited number of unrelated pathogens whose interaction is simplified to simple mutual exclusion. The model incorporates an ongoing development of host immunity to past diseases, while leaving the system open for emergence of new diseases. The model exhibits a rich dynamical behavior with interacting infection waves, leaving broad trails of immunization in the host population. This obtained immunization pattern depends only on the system size and on the mutation rate that initiates new diseases.

Glycaemic control is recognized as one of the important aspects in managing critically ill patients. Both hyperglycaemia and hypoglycaemia independently increase the risk of patient mortality. Hence, the identification of optimal glycaemic control is of paramount importance in the management of critically ill patients. The aim of this literature review is to examine the current status of glycaemic control in critically ill adult patients. This literature review will focus on randomized controlled trials comparing intensive insulin therapy to conventional insulin therapy, with an objective to identify optimal blood glucose level targets for critically ill adult patients. A literature review was conducted to identify large randomized controlled trials for the optimal targeted blood glucose level for critically ill adult patients published since 2000. A total of eight studies fulfilled the selection criteria of this review. With current human and technology resources, the results of the studies support commencing glycaemic control once the blood glucose level of critically ill patients reaches 10 mmol/L and maintaining this level between 8 mmol/L and 10 mmol/L. This literature review provides a recommendation for targeting the optimal blood glucose level for critically ill patients within moderate blood glucose level target range (8-10 mmol/L). The need for uniformed glucometrics for unbiased reporting and further research for optimal blood glucose target is required, especially in light of new technological advancements in closed-loop insulin delivery and monitoring devices. This literature review has revealed a need to call for consensus in the measurement and reporting of glycaemic control using standardized glucometrics. © 2017 British Association of Critical Care Nurses.

Oxidant trade-offs in immunity: an experimental test in a lizard.

Directory of Open Access Journals (Sweden)

Michael Tobler

Full Text Available Immune system functioning and maintenance entails costs which may limit investment into other processes such as reproduction. Yet, the proximate mechanisms and 'currencies' mediating the costs of immune responses remain elusive. In vertebrates, up-regulation of the innate immune system is associated with rapid phagocytic production of pro-oxidant molecules (so-called 'oxidative burst' responses. Oxidative burst responses are intended to eliminate pathogens but may also constitute an immunopathological risk as they may induce oxidative damage to self cells. To minimize the risk of infection and, at the same time, damage to self, oxidative burst activity must be carefully balanced. The current levels of pro- and antioxidants (i.e. the individual oxidative state is likely to be a critical factor affecting this balance, but this has not yet been evaluated. Here, we perform an experiment on wild-caught painted dragon lizards (Ctenophorus pictus to examine how the strength of immune-stimulated oxidative burst responses of phagocytes in whole blood relates to individual oxidative status under control conditions and during an in vivo immune challenge with Escherichia coli lipopolysaccharide (LPS. Under control conditions, oxidative burst responses were not predicted by the oxidative status of the lizards. LPS-injected individuals showed a strong increase in pro-oxidant levels and a strong decrease in antioxidant levels compared to control individuals demonstrating a shift in the pro-/antioxidant balance. Oxidative burst responses in LPS-injected lizards were positively related to post-challenge extracellular pro-oxidants (reflecting the level of cell activation and negatively related to pre-challenge levels of mitochondrial superoxide (suggesting an immunoregulatory effect of this pro-oxidant. LPS-challenged males had higher oxidative burst responses than females, and in females oxidative burst responses seemed to depend more strongly on antioxidant

Understanding the precise role of the immune system in cancer has been hindered by the complexity of the immune response and challenges in measuring immune cell types in health and disease in the context of large epidemiologic studies. In this review, we present the rationale to study immunity in cancer and highlight newly available tools to further elucidate the epidemiologic factors driving individual variation in the immune response in cancer. Here, we summarize key studies that have evaluated the role of immunologic status on risk of cancer, discuss tools that have been used in epidemiologic studies to measure immune status, as well as new evolving methodologies where application to epidemiology is becoming more feasible. We also encourage further development of novel emerging technologies that will continue to enable prospective assessment of the dynamic and complex role played by the immune system in cancer susceptibility. Finally, we summarize characteristics and environmental factors that affect the immune response, as these will need to be considered in epidemiologic settings. Overall, we consider the application of a systems biologic approach and highlight new opportunities to understand the immune response in cancer risk. ©2015 American Association for Cancer Research.

Improving immunization in Afghanistan: results from a cross-sectional community-based survey to assess routine immunization coverage

2017-04-01

Full Text Available Abstract Background Despite progress in recent years, Afghanistan is lagging behind in realizing the full potential of immunization. The country is still endemic for polio transmission and measles outbreaks continue to occur. In spite of significant reductions over the past decade, the mortality rate of children under 5 years of age continues to remain high at 91 per 1000 live births. Methods The study was a descriptive community-based cross sectional household survey. The survey aimed to estimate the levels of immunization coverage at national and province levels. Specific objectives are to: establish valid baseline information to monitor progress of the immunization program; identify reasons why children are not immunized; and make recommendations to enhance access and quality of immunization services in Afghanistan. The survey was carried out in all 34 provinces of the country, with a sample of 6125 mothers of children aged 12–23 months. Results Nationally, 51% of children participating in the survey received all doses of each antigen irrespective of the recommended date of immunization or recommended interval between doses. About 31% of children were found to be partially vaccinated. Reasons for partial vaccination included: place to vaccinate child too far (23%, not aware of the need of vaccination (17%, no faith in vaccination (16%, mother was too busy (15%, and fear of side effects (11%. Conclusion The innovative mechanism of contracting out delivery of primary health care services in Afghanistan, including immunization, to non-governmental organizations is showing some positive results in quickly increasing coverage of essential interventions, including routine immunization. Much ground still needs to be covered with proper planning and management of resources in order to improve the immunization coverage in Afghanistan and increase survival and health status of its children.

[Chronically ill and unemployed? A review on vocational status in multiple sclerosis].

Multiple sclerosis (MS) is one of the most common neurological disorders in young adults. It is characterised by a chronic progressive course with far reaching implications on the patient's private and professional life. Based on the current literature, employment status is analysed in relation to disease-specific, therapeutic, psychosocial, and socioeconomic factors. A special emphasis is placed on the vocational status of MS patients in Germany. According national and international studies, around 40 % of all MS patients are currently unemployed. Main reasons for early retirement are disease-specific factors such as impaired mobility, disability in the upper extremities, fatigue, and cognitive impairment. According to the German Multiple Sclerosis Registry (GMSR), these symptoms are still insufficiently treated. In patients with minor motoric impairment (EDSS ≤ 3.0), depressive symptoms seem to have a major impact on employment status. Disease progression, older age at diagnosis, and hard physical work are negative predictors in terms of employment situation. The lack of flexible working hours, the inability to have flexible resting times at work, a lack of understanding from colleagues and employers as well as the personal attitude were main non-disease-specific reasons for early retirement. The current knowledge on the vocational status in MS is mainly based on international studies (e. g., Scandinavia, England, USA, Australia, MSIF Survey). For Germany, only the GMSR supports significant information on the employment status of MS patients. According to the GMSR, ataxia, fatigue and cognitive dysfunction are still insufficiently treated - a situation that is at least partly due to insufficient treatment options. Comprehensive studies that focus on a broad range of possible influencing factors on vocational status of German MS patients are currently lacking. © Georg Thieme Verlag KG Stuttgart · New York.

Spaceflight impacts human physiology, including well documented immune system dysregulation. Diet, immune function, and the microbiome are interlinked, but diet is the only one of these factors that we have the ability to easily, and significantly, alter on Earth or during flight. As we understand dietary impacts on physiology more thoroughly, we may then improve the spaceflight diet to improve crew health and potentially reduce spaceflight-associated physiological alterations. It is expected that increasing the consumption of fruits and vegetables and bioactive compounds (e.g., omega-3 fatty acids, lycopene, flavonoids) and therefore enhancing overall nutritional intake from the nominal shelf-stable, fully-processed space food system could serve as a countermeasure to improve human immunological profiles, the taxonomic profile of the gut microbiota, and nutritional status, especially where currently dysregulated during spaceflight. This interdisciplinary study will determine the effect of the current shelf-stable spaceflight diet compared to an "enhanced" shelf-stable spaceflight diet (25% more foods rich in omega-3 fatty acids, lycopene, flavonoids, and more fruits, and vegetables in general). The NASA Human Exploration Research Analog (HERA) 2017 missions, consisting of four 45-day missions with closed chamber confinement and realistic mission simulation in a high-fidelity mock space vehicle, will serve as a platform to replicate mission stressors and the effects on crew biochemistry, immunology, and the gut microbiome. Bio sampling of crewmembers is scheduled for selected intervals pre- and in-mission. Data collection also includes dietary intake recording. Outcome measures will include immune markers (e.g., peripheral leukocyte distribution, inflammatory cytokine profiles, T cell function), the taxonomic and metatranscriptomic profile of the gut microbiome, and nutritional status biomarkers and metabolites. Statistical evaluations will determine physiological

Socio-economic status and health in a marginalized group: the role of subjective social status among prison inmates.

One problem in studies of social inequality in health is that traditional socio-economic indicators are unsuitable for groups finding themselves on the outside of those societal arenas from which measures of education, income and occupation are generated. A measure of subjective social position has accordingly been proposed as an addition to the traditional objective socio-economic measures. The present study investigates this concepts' usefulness as an addition to objective SES markers in a sample of prison inmates, known for their marginalized position in society as well as their poor health. Analyses are based on the male part (n = 225) of a nationally representative sample of prison inmates in Norway. Outcome measures are self-rated health, long-standing illness or disability, mental health problems, perceived change in health status and drug use. Analyses of correlation as well as multivariate logistic regression analyses were performed. Subjective social status was bivariately related to all of the health outcomes, except long-standing illness. Multivariate analyses indicated that subjective social status influenced the odds of experiencing mental health problems, but not any of the other health outcomes when controlling for the other independent variables. Subjective social status may add important information to our understanding of the relationship between social disadvantage and mental health in a marginalized social group such as prison inmates.

Immunization is the most cost-effective method to prevent and control vaccine-preventable diseases. Migrant population in China has been rising rapidly, and their immunization status is poor. China has tried various strategies to strengthen its health system, which has significantly improved immunization for migrants. This study applied a qualitative retrospective review method aiming to collect, analyze and synthesize health system strengthening experiences and practices about improving immunizations for migrants in China. A conceptual framework of Theory of Change was used to extract the searched literatures. 11 searched literatures and 4 national laws and policies related to immunizations for migrant children were carefully studied. China mainly employed 3 health system strengthening strategies to significantly improve immunization for migrant population: stop charging immunization fees or immunization insurance, manage immunization certificates well, and pay extra attentions on immunization for special children including migrant children. These health system strengthening strategies were very effective, and searched literatures show that up-to-date and age-appropriate immunization rates were significantly improved for migrant children. Economic development led to higher migrant population in China, but immunization for migrants, particularly migrant children, were poor. Fortunately various health system strengthening strategies were employed to improve immunization for migrants in China and they were rather successful. The experiences and lessons of immunization for migrant population in China might be helpful for other developing countries with a large number of migrant population.

The aim of this research study was to examine the relationship between 4 sources of social support (support for the adolescent from family, support for the adolescent from friends, support for the caregiver from another adult, and support to the family from the health care provider) and adolescents' diabetes outcomes (illness management behavior and health status) using a diverse sample of urban adolescents. One hundred forty-one adolescents with insulin-managed diabetes and their primary caregivers completed questionnaires assessing social support and illness management behavior. Glucose meters were downloaded and hemoglobin A1c assays were obtained. Structural equation modeling was used to test a model social support informed by social ecological theory. The results of the structural equation modeling indicated that support for the caregiver from another adult was directly and positively related to support for the adolescent from family and indirectly related to better illness management. Support for the adolescent from family was directly related to better diabetes management and, through better management, to better diabetes health. Support to the family from the health care provider was not related to support for the adolescent and support to the adolescent from friends was not related to illness management, as hypothesized. This study identifies a novel target for social support intervention to improve adolescents' illness management behavior-the caregivers of adolescents with diabetes. By enhancing the social support caregivers receive from other adults in their lives, caregivers' ability to support their adolescent children with diabetes might also be improved which, in turn, improves adolescents' illness outcomes.

Full Text Available Background: Illness representations (based on Leventhal's model are associated with chronic illness outcomes. It has been suggested that targeting these cognitive components improves illness outcomes. Multiple sclerosis is a common disorder between neural and immune systems that creates physical and psychological consequences. There are few pre psychological trails on these patients. The aim of this study was to determine effectiveness of cognitive-behavior therapy on altering illness representations and improving emotional states of the patients.Methods: By using a randomized controlled trial design, among 52 selected patients, 35 volunteers randomly were allocated into intervention and control groups. An extensive interventional cognitive behavior therapy based package was conducted to intervention group in 10 weekly sessions. The control group stayed in waiting list and participated in 5 group meeting sessions. (IPQR and (DASS-42 psychological scales were administered, Leven and T statistical tests were applied for dat analysis.Results: The results showed positive changes in four illness representation components of patients including illness (identity, consequences, coherence and personal control. Associated improvement occurred in depression, anxiety, stress and emotional representations.Conclusion: Mooney and Padeskey's theoretically based cognitive-behavior therapy, is effective on illness representations modification and improving emotional states of the patients. The findings are less similar to Goodman's trial on Systemic Lupus Erythematosus patients and more similar to Petrie's trail on cardiac patients.

Full Text Available This study evaluated the effects of dietary anticoccidial drugs plus antibiotic growth promoters (AGPs on parameters of immunity in commercial broiler chickens. Day-old chicks were raised on used litter from a farm with endemic gangrenous dermatitis to simulate natural pathogen exposure and provided with diets containing decoquinate (DECX or monensin (COBN as anticoccidials plus bacitracin methylene disalicylate and roxarsone as AGPs. As a negative control, the chickens were fed with a non-supplemented diet. Immune parameters examined were concanavalin A (ConA-stimulated spleen cell proliferation, intestine intraepithelial lymphocyte (IEL and spleen cell subpopulations, and cytokine/chemokine mRNA levels in IELs and spleen cells. ConA-induced proliferation was decreased at 14 d post-hatch in DECX-treated chickens, and increased at 25 and 43 d in COBN-treated animals, compared with untreated controls. In DECX-treated birds, increased percentages of MHC2+ and CD4+ IELS were detected at 14 d, but decreased percentages of these cells were seen at 43 d, compared with untreated controls, while increased TCR2+ IELs were evident at the latter time. Dietary COBN was associated with decreased fractions of MHC2+ and CD4+ IELs and reduced percentages of MHC2+, BU1+, and TCR1+ spleen cells compared with controls. The levels of transcripts for interleukin-4 (IL-4, IL-6, IL-17F, IL-13, CXCLi2, interferon-γ (IFN-γ, and transforming growth factorβ4 were elevated in IELs, and those for IL-13, IL-17D, CXCLi2, and IFN-γ were increased in spleen cells, of DECX- and/or COBN-treated chickens compared with untreated controls. By contrast, IL-2 and IL-12 mRNAs in IELs, and IL-4, IL-12, and IL-17F transcripts in spleen cells, were decreased in DECX- and/or COBN-treated chickens compared with controls. These results suggest that DECX or COBN, in combination with bacitracin and roxarsone, modulate the development of the chicken post-hatch immune system.

Individuals with serious mental illness and veterans are two populations at elevated risk for suicide; however, research has not examined whether veterans with serious mental illness may be at higher suicide risk than nonveterans with serious mental illness. Additionally, overlapping risk factors for suicide in these populations may account for differences in suicide-related outcomes between these groups. Therefore, the aim of this study was to identify differences in death ideation and suicide ideation among veterans and nonveterans with serious mental illness. We also aimed to explore these effects after adjusting for potentially shared risk factors. We found that veterans with serious mental illness reported death ideation and suicide ideation more than twice as often as nonveterans with serious mental illness. After adjusting for demographic, psychiatric, and theory-driven risk factors, the effect of veteran status on death ideation remained significant, though the effect on suicide ideation was no longer significant. Depressive and psychotic symptoms were significant predictors of death ideation; depressive symptoms and hostility were significant predictors of suicide ideation. Clinicians should particularly monitor death ideation and suicide ideation in veterans with serious mental illness, as well as associated clinical risk factors such as depression, psychotic symptoms, and hostility.

Joo, J Y; Liu, M F

2018-03-01

This qualitative systematic review aimed to identify and synthesize recent qualitative studies to improve understanding of the experiences and perceptions of case management interventions that individuals with chronic illnesses and their caregivers have. Case management has been shown to be effective at improving quality of care and lowering costs for individuals with chronic illnesses. However, no qualitative review has been synthesized with recent qualitative studies about case management experiences by individual with chronic illnesses. This qualitative systematic review uses a thematic synthesis method to review 10 qualitative studies published within the last 10 years, from 2007 to 2016, thereby identifying and discussing the understandings that individuals with chronic illnesses and their caregivers have about case management. From this synthesis, three themes were identified as facilitators of case management (access to healthcare resources, health status supports and emotional aid) and two themes were identified as barriers to it (low information about case management and time constraints). This is the first qualitative systematic review of the perceptions and experiences that individuals with chronic illnesses and their caregivers have about case management. The facilitators of case management can be employed to inform patients about the benefits of case management and to improve population health. The findings about barriers to case management can be used to reform case management for populations with chronic illnesses. These factors should be considered by nursing researchers and healthcare policymakers when implementing case management. © 2018 International Council of Nurses.

Mental illness is stigmatized in most of the communities and people with such illness are often subjected to defame. Stigma impairs an individual's and their caregiver's physical, social and emotional wellbeing, and health-seeking behavior. Sufficient literature on how often the caregivers of people with mental illness from low and middle-income countries are stigmatized and how they perceive people with mental illness is unavailable. In this study, we examined caregivers' attitude towards people with mental illness and perceived stigma. We conducted face-to-face interviews with 170 caregivers in an outpatient clinic of a hospital in Nepal using a structured questionnaire. We calculated median and inter-quartile range of the attitude and perceived stigma scores. To assess the correlates, Kruskal Wallis H test and Mann Whitney U test were carried out. Overall median score for the domains: attitude (score range: 18-90) and perceived stigma (score range: 12-60) were 42 and 28 respectively, inter-quartile range being 8 each. Attitude score differed significantly by the sex of caregiver (pattitude towards mental illness. Similarly, sex of participant, marital status, educational status, occupation, caregiver's relation with patient and use of alternative treatment modalities were correlates of perceived stigma. Findings of this study suggest that interventions targeting these high-risk populations might be beneficial to help build a positive attitude and overcome the perceived social stigma.

Routine Immunization of Adults in Canada: Review of the Epidemiology of Vaccine-Preventable Diseases and Current Recommendations for Primary Prevention

2009-01-01

Full Text Available Vaccination is one of the greatest achievements in public health of the 20th century. However, the success of vaccine uptake and adherence to immunization guidelines seen in pediatric populations has not been observed among adult Canadians. As a result of the disparity in susceptibility to vaccine-preventable disease, there has been an increasing shift of vaccine-preventable childhood diseases into adult populations. Accordingly, morbidity and mortality due to vaccine-preventable illnesses now occur disproportionately in adults. All Canadians, irrespective of age, should have immunity to measles, mumps, rubella, tetanus, diphtheria, pertussis and varicella. All adult Canadians with significant medical comorbidities or those older than 65 years of age should receive the pneumococcal polysaccharide vaccine and yearly trivalent inactivate influenza vaccines. The present review summarizes the burden of illness of these vaccine-preventable diseases in the Canadian adult population and reviews the current immunization recommendations. Vaccination of all Canadians to these common agents remains a vital tool to decrease individual morbidity and mortality and reduce the overall burden of preventable disease in Canada.

The contribution of specific symptoms on ratings of global illness severity in patients with schizophrenia is not well understood. The present study examined the clinical determinants of clinician and patient ratings of overall illness severity. This study included 1,010 patients with a DSM-IV diagnosis of schizophrenia who participated in the baseline visit of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study conducted between January 2001 and December 2004 and who had available symptom severity, side effect burden, cognition, and community functioning data. Both clinicians and patients completed the 7-point Clinical Global Impressions-Severity of Illness scale (CGI-S), the primary measure of interest in the present study. Symptoms were rated using the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia, and functional status with the Quality of Life Scale. Neurocognition, insight, and medication-related side effects were also evaluated. Clinicians rated illness severity significantly higher than patients (P negative, disorganized, and depressive symptoms, as well as functional outcome (all P values enhance patient engagement in care and improve outcomes.

As part of an investigation of the interaction of X-rays and immune cytotoxicity in tumour control, an experimental mouse model system has been used in which quantitative anti-tumour immunity was raised in prospective recipients of tumour-cell suspensions exposed to varying doses of X-rays in vitro before injection. Findings reported here indicate that, whilst X-rays kill a proportion of cells, induced immunity deals with a fixed number dependent upon the immune status of the host, and that X-rays and anti-tumour immunity do not act synergistically in tumour-cell killing. The tumour used was the ascites sarcoma BP8. (author)

Good nutrition is necessary for the growth and development of preschool children. In sub-Saharan Africa, however, data on the determinants of their nutritional status are lacking. A cross-sectional survey of 366 preschool children was conducted in a rural community in northern Nigeria. Anthropometric measurements of the children were taken and information about feeding practices, immunization and parental education was obtained from their mothers. Fifty-two percent were stunted, 30% were underweight and 25% were wasted. Recent history of diarrhea was associated with wasting (OR = 2.66, p Children whose fathers had postsecondary education were less likely to be stunted (OR = 0.45, p = 0.01) or underweight (OR = 0.37, p = 0.005). Promoting exclusive breastfeeding, preventing recurrent diarrhea and including fathers in community interventions will improve the health of children in this community. © The Author [2014].

Sobralske, Mary

2006-08-01

To inform nurse practitioners (NPs) about Mexican American men's health and illness beliefs and the ways in which these are influenced by their masculine identity and how they view themselves as men in their culture. The data sources used were based on a selected review of the literature about Mexican American men's health and illness beliefs and the concept of machismo. Several studies, including the author's study on Mexican American men's healthcare-seeking beliefs and behaviors and experience in providing primary health care to men across cultures, contributed new data. The meaning of manhood in the Mexican American culture is critical in understanding how men perceive health and illness and what they do when they are ill. Machismo enhances men's awareness of their health because they have to be healthy to be good fathers, husbands, brothers, sons, workers, and community members. Pain and disability are motivating factors in finding ways to regain their health. Men's health beliefs across cultures need further investigation by nurse researchers and NPs. How culture influences healthcare delivery to men should be better understood. If NPs are aware of men's views on masculinity, they are better prepared to understand and assist men in becoming more aware of their health status and to seek health care when appropriate.

What Influences Mental Illness? Discrepancies Between Medical Education and Conception.

Einstein, Evan Hy; Klepacz, Lidia

2017-01-01

This preliminary study examined the differences between what was taught during a formal medical education and medical students' and psychiatry residents' conceptions of notions regarding the causes and determinants of mental illness. The authors surveyed 74 medical students and 11 residents via convenience sampling. The survey contained 18 statements which were rated twice based on truthfulness in terms of a participant's formal education and conception, respectively. Descriptive statistics and a Wilcoxon signed rank test determined differences between education and conception. Results showed that students were less likely to perceive a neurotransmitter imbalance to cause mental illness, as opposed to what was emphasized during a formal medical education. Students and residents also understood the importance of factors such as systemic racism and socioeconomic status in the development of mental illness, which were factors that did not receive heavy emphasis during medical education. Furthermore, students and residents believed that not only did mental illnesses have nonuniform pathologies, but that the Diagnostic and Statistical Manual of Mental Disorders also had the propensity to sometimes arbitrarily categorize individuals with potentially negative consequences. If these notions are therefore part of students' and residents' conceptions, as well as documented in the literature, then it seems appropriate for medical education to be further developed to emphasize these ideas.

The Impact of Illness Identity on Recovery from Severe Mental Illness.

Yanos, Philip T; Roe, David; Lysaker, Paul H

2010-04-01

The impact of the experience and diagnosis of mental illness on one's identity has long been recognized; however, little is known about the impact of illness identity, which we define as the set of roles and attitudes that a person has developed in relation to his or her understanding of having a mental illness. The present article proposes a theoretically driven model of the impact of illness identity on the course and recovery from severe mental illness and reviews relevant research. We propose that accepting a definition of oneself as mentally ill and assuming that mental illness means incompetence and inadequacy impact hope and self-esteem, which further impact suicide risk, coping, social interaction, vocational functioning, and symptom severity. Evidence supports most of the predictions made by the model. Implications for psychiatric rehabilitation services are discussed.

This study was conducted to determine susceptibility to Rubella in women who are going to marry or consult for pregnancy. Methods: This study began in 1997 and ended in 2000. The study was analytic descriptive and prospective. Eight hundred and thirty eight women who referred for premarriage tests or counselling for conception were included. According to antibody levels, test results were reported as immune and non-immune (susceptible for every individual. Results: Among 838 cases, 253 women (30.1% were non-immune (susceptible and 585 women (69.9% were immune. The educational status of the two groups were recorded. Analysis of data showed that the higher the educational level (62.2% for University degree holder, the lower the immunity against Rubella would be (75.2% for unfinished high school individuals. Furthermore, immunity in the younger group was higher (73.9% in <20 years than in the older group(61% in >30 years. Conclusion: More than one third of pre marriage and pre conceptional women were non-immune (susceptible to Rubella, so health providers should be aware of Rubella prevention and control in childbearing age via screening and vaccination. Immunity against Rubella can vary over time and the socioeconomic status is believed to play an important role in the level of immunity.

Delayed radiation effects of irradiation at relatively high doses - 0.52- 2 Gy in result of severe accidents are discussed. The immune response of lymphocyte populations manifested in formation of different kind of mutant cells at Hiroshima-A-bombing and Chernobyl accident are presented. It is of great interest the hypothesis presented launched by RERF (Japanese Foundation for Radiation Effect Research, Hiroshima) for radiation induced predominant of T H2 -lymphocytes in comparison to T H1 as delayed immune response at the Hiroshima-A-bomb survivors. The aspect of immune status is quite different at low doses irradiation (0.02 - 0.2 Gy). There is some stimulation in immune response known as hormesis effect. It is suggested that T-cell activation has key role in immune system stimulation at doses under 0.2 Gy. There is also activation of DNA-reparation mechanisms. Suppression of the hypothalamus-hypophysis-suprarenal axis brings to enhancing of immune potential. Chinese people living in a region with three-times higher background radiation, X-ray examined patients as well as occupationally exposed personnel have been investigated. Radioprotective effect of some cytokines and their influence on the individual radiosensitivity are also discussed.The investigations have to be continued because of some inconsistent results

This study aims to describe the socio-demographic and clinical profile of elderly people with chronic illness and correlate with perceived family support. This is a cross-sectional, analytical study of 294 elderly people (51.4% female, patients at the Health Centre in the district of Viseu - Portugal, diagnosed with chronic illness (77.9% cardiovascular; Mean age was 72.22 ± 6.13, 70.7% were married and 52% had 4 years of schooling; Data was gathered using a questionnaire and the Family APGAR (Adaptation, Partnership, Growth, Affection and Resolve. In relation to family functionality, 18.7% perceive families as highly functional, 26.9% mildly dysfunctional and 54.4% severely dysfunction. There is a statistically significant relationship between the family APGAR and the presence of chronic illness (p < 0.001. We found no statistical significance between the family APGAR and gender (p = 0.26, age (p = 0.26, marital status (p = 0.32 and educational level (p = 0.28. Economic, political and social changes in our society has an impact on the family and the support they provide which is manifested among vulnerable groups, as is the case of an elderly person with chronic illness. Thus, we propose specialised psychological support for this age group which is more vulnerable and without the needed support from within the family.

Stigma towards people with mental illness is a worldwide concern. A five-nation survey of medical student attitudes towards people with mental illness recently reported far lower levels of social acceptance among Chinese medical students compared to those from the US, Brazil, Ghana, and Nigeria. This qualitative study presented recent Chinese medical school graduates with probes based on questions used in the aforementioned cross-national study to elicit their views of factors underlying the negative attitudes towards social acceptance of people with mental illness. One-hour interviews were conducted with twenty psychiatry residents in June, 2016. Of 241 coded responses concerning negative attitudes, 51.5% were coded as reflecting fear of violent behavior, 22.8% as loss of face (i.e. shame from interpersonal associations), 17.0% lowered social status, 4.98% nonconforming social behavior, and 3.73% the heritability of mental illness. Low levels of social acceptance of individuals with mental illness among medical students in China are largely related to fears of violence of and loss of face. Understanding the attitudes of medical students may inform efforts to reduce stigma through educational initiatives targeted at both medical students and the general public.

In the present study, the sexual dimorphism in immune response in the seahorse Hippocampus erectus in which males compete for mates and invest heavily in parental care was assessed. Variability in immunocompetence in virginal seahorses with differing levels of sexual maturity (i.e., immaturity, early maturity and maturity) and with different mating statuses (i.e., virginal, experienced mating failure and experienced mating success) were analyzed by evaluating immune parameters in the plasma. Additionally, ultrastructural characteristics of the inner epithelium of the brood pouch were compared between males that had experienced mating failure and those that had succeeded. Generally, immunity in sexually mature virgin males was greater than in females, and mating competition significantly reduced males' immunity. However, parental care gave males stronger immune and metabolic abilities and resulted in their immunity significantly rebounding after a successful mating. The present study quantitatively clarifies, for the first time, how parental care and mating competition jointly affect immunity. Moreover, previous findings that females display more efficient immune defenses than males in conventional species (i.e., males are as competitor and females as care giver) and that males' immunity is higher than females' in the pipefish (i.e., females are as competitor and males as care giver) in combination with the present results indicate that parental care is a key factor for sexual dimorphism in immunity. The care-giving sex has strong immunity regardless of the sex in charge of mating competition or not. Copyright © 2016 Elsevier Ltd. All rights reserved.

The life expectancy of adults with mental illness is worse than that of the general population and is largely due to poor physical health status. Physical activity has been consistently recommended for the prevention and management of many chronic physical health conditions and can also have benefits for mental health. This cross sectional study assessed the attitudes towards and preferences for physical activity among inpatient adults with mental illness, and differences by distress and gender. Self-report questionnaires were completed by 101 patients. Findings indicated that inpatient adults with mental illness are interested in doing physical activity while in hospital, primarily to maintain good physical health and improve emotional wellbeing. Fewer than half of participants agreed that physical activity has benefits for serious mental illness. Participants indicated a preference for walking and physical activity that can be done alone, at a fixed time and with a set routine and format. Major barriers were fatigue and lack of motivation. Females were more likely than males to prefer activities done with others of the same gender (P = 0.001) and at the same level of ability (P physical activity intervention programming in hospital settings, which may contribute to decreasing the chronic disease burden and improve the psychological wellbeing in adults with mental illness. © 2015 Australian College of Mental Health Nurses Inc.

Possibilities of Correction and Prophylaxis of Intestinal Microbiocenosis Disorders in Frequently Ill Children

Full Text Available Frequently and protractedly ill children constitute a special for pediatricians group of patients. Acute respiratory infections with severe and frequently relapsing course badly affect children’s health and contribute to the decrease of the functional activity of the immune system. Risk factors of the high prevalence of acute respiratory infections are changes in the immune responses at the background of unfavorable ante- and perinatal conditions, numerous contacts with potential causative agents at the beginning of attendance of infant schools, widespread intra- and inter-family contacts as well as susceptibility to Th2 immune response (allergy and prolonged course of inflammatory process. Etiotropic treatment of acute respiratory infections often includes antibacterial drugs, which, however, have negative effects on intestinal microflora, such as dyspeptic syndrome and antibiotic-induced diarrhea. Intestinal dysbiosis affects homeostasis, leads to significant changes in functional activity of various organs and systems. That is why correction and prophylaxis of intestinal dysbacteriosis is very important in pediatric practice. In this article the main data on epidemiology, pathogenesis, forms, clinical manifestation, diagnostics and treatment of antibiotic-induced diarrhea in children.

BILL E. KUNKLE INTERDISCIPLINARY BEEF SYMPOSIUM: Impact of mineral and vitamin status on beef cattle immune function and health.

Kegley, E B; Ball, J J; Beck, P A

2016-12-01

The importance of optimal mineral and vitamin nutrition on improving immune function and health has been recognized in the preceding decades. In the southeast, beef cattle are raised predominantly on forages that may be limiting in nutrients for optimal health, especially trace minerals such as Cu, Zn, and Se. Clinical deficiencies of these nutrients produce classic symptoms that are common to several nutrient deficiencies (e.g., slow growth and unthrifty appearance); however, subclinical deficiencies are more widespread and more difficult to detect, yet may result in broader economic losses. Dietary mineral concentrations often considered adequate for maximum growth, reproductive performance, or optimal immune function have been found to be insufficient at times of physiological stress (weaning, transport, comingling, etc.), when feed intake is reduced. The impacts of these deficiencies on beef cattle health are not apparent until calves have been subjected to these stressors. Health problems that are exacerbated by mineral or vitamin deficiencies include bovine respiratory disease, footrot, retained placenta, metritis, and mastitis. Many micronutrients have antioxidant properties through being components of enzymes and proteins that benefit animal health. In dairy cattle, high levels of supplemental Zn are generally associated with reduced somatic cell counts and improved foot health, possibly reflecting the importance of Zn in maintaining effective epithelial barriers. Neutrophils isolated from ruminants deficient in Cu or Se have reduced ability to kill ingested bacteria in vitro. Supplemental vitamin E, in its role as an intracellular antioxidant has been shown to decrease morbidity in stressed calves. There is more understanding of the important biological role that these nutrients play in the functioning of the complex and multifaceted immune system. However, there is still much to be learned about determining the micronutrient status of herds (and hence

Isotope-based immunological techniques. Their use in assessment of immune competence and the study of immune responses to pathogens

International Nuclear Information System (INIS)

Duffus, W.P.H.

1984-01-01

The influence of isotope-based techniques on both assessment of immune competence and immune response to pathogens is discussed. Immunodeficiencies acquired as a result of factors like malnutrition and concomitant disease can severely affect not only attempts to intensify and improve production but also successful immune response against important vaccines such as rinderpest and foot-and-mouth disease. Isotope-based techniques, with their accuracy, speed and small sample volume, are ideally suited for assessing immunocompetence. One of the main drawbacks remains antigen purity, an area where research should now be concentrated. Lymphocyte transformation is widely used to assess cell-mediated immuno-competence but techniques to assess biological functions such as phagocytosis and cell-mediated cytotoxicity could more usefully reflect immune status. These latter techniques utilize isotopes such as 3 H, 14 C, 32 P and 125 I. Investigation of specific cell-mediated immune response often requires a labelled target. Suitable isotopes such as 51 Cr, 99 Tcsup(m), 75 Se and 3 H are compared for their capacity to label both mammalian and parasite targets. Suggestions are made on a number of areas of research that might usefully be encouraged and supported in order to improve applied veterinary immunology in tropical countries. (author)

Full Text Available ABSTRACT The government had held sub-national diphtheria immunization days in 2012 to combat an outbreak of diphtheria in East Java province. However, there werestill regencies or cities which had high incidence and Bangkalanregencywas the highest. The research aimed to analyze the determinants of diphtheria in Bangkalan after SNIDs. This research was case control study with 31 subjects as case and 124 as control spread in 25 case villages and 25 control villages. Bivariate analysis used chi-square and simple logistic regression. Multivariate analysis used logistic regression. Bivariate analysisresult showed that individual and household variables that had associate with incidence of diphtheria in the Bangkalan after SNIDs of diphtheria vaccine in 2012 were DPT immunization status, the status of SNIDs, age, and mother's education level. In this study, there were not associate between village variables with diphtheria in the Bangkalan after SNIDs. Multivariate analysis result showed that had associate with incidence of diphtheria in Bangkalan after SNIDs were no DPT immunization (p=0,012; OR=4,765, incomplete DPT immunization (p=0,001; OR=6,276, 3-7 years of age (p=0,014; OR=15,137, 7-15 years of age (p=0,001;OR=41,984, and no immunization in SNIDs (p=0,020; OR=3,553. Conclusion, the dominantfactors that affected diphtheriainBangkalanwere status of DPTimmunization, ageand the SNIDs of diphtheria.

Cerebral ischemia has been shown to result in peripheral inflammatory responses followed by long-lasting immunosuppression. Our recent study demonstrated that intravenous delivery of regulatory T cells (Tregs) markedly protected against transient cerebral ischemia by suppressing neutrophil-derived matrix metallopeptidase 9 production in the periphery. However, the effect of Tregs on systemic inflammatory responses and immune status has not been fully characterized. Cerebral ischemia was induced by middle cerebral artery occlusion for 60 minutes in mice or 120 minutes in rats. Tregs were isolated from donor animals by CD4 and CD25 double selection and transferred intravenously to ischemic recipients at 2 hours after middle cerebral artery occlusion. Animals were euthanized on different days after reperfusion. The effects of Tregs on systemic inflammation and immune status were evaluated using flow cytometry, ELISAs, and immunohistochemistry. Systemic administration of purified Tregs raises functional Tregs in the blood and peripheral organs, including spleen and lymph nodes. These exogenous Tregs remain in the blood and peripheral organs for ≥12 days. Functionally, Treg adoptive transfer markedly inhibits middle cerebral artery occlusion-induced elevation of inflammatory cytokines (interleukin-6 and tumor necrosis factor α) in the blood. Furthermore, Treg treatment corrects long-term lymphopenia and improves cellular immune functions after ischemic brain injury. As a result, Treg-treated animals exhibit decreased bacterial loads in the blood during recovery from cerebral ischemic attack. Treg treatment did not exacerbate poststroke immunosuppression. On the contrary, Treg-treated animals displayed improved immune status after focal cerebral ischemia.

Keeping the immune system in check: a role for mitophagy.

Science.gov (United States)

Lazarou, Michael

2015-01-01

Mitochondria play a central role in many facets of cellular function including energy production, control of cell death and immune signaling. Breakdown of any of these pathways because of mitochondrial deficits or excessive reactive oxygen species production has detrimental consequences for immune system function and cell viability. Maintaining the functional integrity of mitochondria is therefore a critical challenge for the cell. Surveillance systems that monitor mitochondrial status enable the cell to identify and either repair or eliminate dysfunctional mitochondria. Mitophagy is a selective form of autophagy that eliminates dysfunctional mitochondria from the population to maintain overall mitochondrial health. This review covers the major players involved in mitophagy and explores the role mitophagy plays to support the immune system.

Nutritional strategies to optimize dairy cattle immunity.

Sordillo, L M

2016-06-01

Dairy cattle are susceptible to increased incidence and severity of both metabolic and infectious diseases during the periparturient period. A major contributing factor to increased health disorders is alterations in bovine immune mechanisms. Indeed, uncontrolled inflammation is a major contributing factor and a common link among several economically important infectious and metabolic diseases including mastitis, retained placenta, metritis, displaced abomasum, and ketosis. The nutritional status of dairy cows and the metabolism of specific nutrients are critical regulators of immune cell function. There is now a greater appreciation that certain mediators of the immune system can have a reciprocal effect on the metabolism of nutrients. Thus, any disturbances in nutritional or immunological homeostasis can provide deleterious feedback loops that can further enhance health disorders, increase production losses, and decrease the availability of safe and nutritious dairy foods for a growing global population. This review will discuss the complex interactions between nutrient metabolism and immune functions in periparturient dairy cattle. Details of how either deficiencies or overexposure to macro- and micronutrients can contribute to immune dysfunction and the subsequent development of health disorders will be presented. Specifically, the ways in which altered nutrient metabolism and oxidative stress can interact to compromise the immune system in transition cows will be discussed. A better understanding of the linkages between nutrition and immunity may facilitate the design of nutritional regimens that will reduce disease susceptibility in early lactation cows.

INFOVAC is a network providing information about immunization issues to health professionals. The aim of this study was to assess the attitude of INFOVAC subscribers toward the current Swiss immunization schedule, potential modifications, and current and hypothetical immunization practices regarding their own children. In March 2015, a Web-based survey was sent to 4260 physicians and pharmacists subscribed to INFOVAC. Participation was anonymous and voluntary. The following information was obtained: (1) current immunization status of own children; (2) which immunizations would currently be accepted for a hypothetical own child and (3) attitudes toward potential modifications of the Swiss immunization schedule. Descriptive methods and multivariate models to correct for covariables were used for data analysis. Nine hundred and fifty-five valid questionnaires were received: 886/3704 (23.9%) from physicians and 69/556 (12.4%) from pharmacists. Current (>95%) and hypothetical (>99%) immunization rates were high for diphtheria, tetanus, pertussis, poliomyelitis and measles-mumps-rubella. Most pediatricians (61%) would support more vaccines for their children than currently recommended by the Swiss immunization advisory committee, whereas about 50% of other physicians and pharmacists would decline at least one of the recommended immunizations, most frequently varicella, pneumococcal or meningococcal C conjugate vaccines. Strong general support was expressed for the expansion of human papillomavirus immunization to males, acceleration of the measles-mumps-rubella schedule and a 2 + 1 instead of 3 + 1 diphtheria-tetanus-pertussis, acellular-inactivated poliomyelitis vaccine (DTPa-IPV)/Haemophilus influenzae type b ± hepatitis B virus (HBV) schedule. Survey participants generally demonstrated a positive attitude toward immunization, with pediatricians being the most progressive subgroup with the largest percentage of participants (63.1%) neither declining nor postponing any

A balanced review of the status T cell-based therapy against cancer

Marincola Francesco M

2005-04-01

Full Text Available Abstract A recent commentary stirred intense controversy over the status of anti-cancer immunotherapy. The commentary suggested moving beyond current anti-cancer vaccines since active-specific immunization failed to match expectations toward a more aggressive approach involving the adoptive transfer of in vitro expanded tumor antigen-specific T cells. Although the same authors clarified their position in response to others' rebuttal more discussion needs to be devoted to the current status of T cell-based anti-cancer therapy. The accompanying publications review the status of adoptive transfer of cancer vaccines on one hand and active-specific immunization on the other. Hopefully, reading these articles will offer a balanced view of the current status of antigen-specific ant-cancer therapies and suggest future strategies to foster unified efforts to complement either approach with the other according to specific biological principles.

The aim of the study was to define local immune and oxidative changes in patients with exacerbated chronic apical periodontitis. These changes were assessed in saliva of 67 patients with the mean age of 31±2.5 before and after treatment. The study revealed disturbances in cytokines and complement system balance and activation of lipids peroxidation. Combination of Gepon or Vobenzim with Essentiale forte H and Kaskatol proved to be the most effective for correction of this imbalance.

In this report we describe a patient with a benign glioma treated with surgery and radiation. After a period of stability he developed subacute bacterial endocarditis, and deteriorated neurologically. Computed tomographic scans did not show recurrent tumor. An angiogram showed vasculitis restricted to the previously irradiated area. Secondary to subacute bacterial endocarditis was the presence of high levels of circulating immune complexes. His neurological status was unchanged after antibiotics, but improved after treatment with dexamethasone. We interpret the clinical course as an immune-complex-mediated vasculitis superimposed on a subclinical radiation vasculitis. This case supports the hypothesis that immune mechanisms may be involved in delayed radiation injury to the nervous system.

Immunological blood parameters and the effects of environmental pollutants on the immune system are important to assess the health status of seals. Animals living permanently in seal centres are useful for development and validation of diagnostic tools for free-ranging animals. In this study, parameters of cellular immunity as well as metal concentrations in blood and metal influence on cell proliferation of seven seals from a seal centre were investigated repeatedly using multi-element analysis and a lymphocyte proliferation assay. The metal concentrations, except for tin and chromium, were in general comparable to those of free-ranging animals of the North Sea. The unstimulated and mitogen-stimulated lymphocyte proliferation showed strong intra- and inter-individual variability, which reflected variability in activation of the immune status. Furthermore, both immunosuppressive and stimulative influences of metals on lymphocytes were found. Summarising, the methods used in this investigation provided useful information on these animals, and their application to free-ranging animals can be recommended

Full Text Available Background and Objectives Chronic renal disease is a threatening condition for the health, economic, and social status of the affected person and his/her family. Patients undergoing hemodialysis encounter mental and health problems; the current study aimed at predicting resilience via social support and illness perceptions among patients undergoing hemodialysis. Methods The current descriptive-correlational study had a statistical population including 308 patients undergoing hemodialysis in Kerman, Iran, in 2017. Based on the Krejcie-Morgan table, the minimum required sample size was 169. The sample was selected using a convenience sampling method. Data collection tools were the Connor-Davidson resilience scale, the medical outcome study (MOS social support survey developed by Sherbourne and Stewart, and the brief illness perception questionnaire developed by Broadbent et al. Data were analyzed using a Pearson correlation coefficient and a stepwise regression analysis via SPSS version 19. Results Results indicated that resilience was significantly and positively related to social support (r = 0.318, P < 0.05 and illness perceptions (r = 0.165, P < 0.05. Among the subscales of social support, emotional support, tangible support, and social interaction could predict resilience, and among the subscales of illness perceptions, only cognitive representation could predict resilience. Conclusions The obtained results demonstrated that resilience was significantly and positively related to social support and illness perceptions. Additionally, the subscales of social support and illness perceptions could predict resilience among the patients undergoing hemodialysis.

Estrogen plays an important role in the regulation of cardiovascular physiology and the immune system by inducing direct effects on multiple cell types including immune and vascular cells. Sex steroid hormones are implicated in cardiovascular protection, including endothelial healing in case of arterial injury and collateral vessel formation in ischemic tissue. Estrogen can exert potent modulation effects at all levels of the innate and adaptive immune systems. Their action is mediated by interaction with classical estrogen receptors (ERs), ERα and ERβ, as well as the more recently identified G-protein coupled receptor 30/G-protein estrogen receptor 1 (GPER1), via both genomic and non-genomic mechanisms. Emerging data from the literature suggest that estrogen deficiency in menopause is associated with an increased potential for an unresolved inflammatory status. In this review, we provide an overview through the puzzle pieces of how 17β-estradiol can influence the cardiovascular and immune systems.

Infant morbidity and mortality rates remain high in Indonesia, with acute respiratory illnesses (ARI) and diarrhea the leading two health problems in children under 5 years. We aimed to describe the nutritional status, feeding practice and case management of ARI and diarrhea of infants from two regions of Indonesia during the first 6 months of life. This study was an observational study conducted in parallel to an immunogenicity and efficacy trial of an oral rotavirus vaccine (RV3-BB) in the Klaten and Yogyakarta regions, Indonesia. Mothers were interviewed at 3 time points: within the first 6 days of their infant's life, and at 8-10 and 22-24 weeks of age. Questions asked included pregnancy history, infant nutritional status, feeding status and health of infants within up to 2 weeks prior to the assessment. Between February 2013 and January 2014, 233 mother-infant pairs were recruited. 60% (136/223) of infants were exclusively breastfed (EBF) until 6 months of age with the strongest support for EBF reported by mothers themselves 70% (101/223) and 25% (36/223) from their partners. At 6 months, 6% (14/223) of infants were underweight and severely underweight; 4% (8/ 223) wasted and severely wasted; and 12% (28/223) were stunted and severely stunted. Non-recommended medication use was high, with 54% (21/39) of infants with reported cough within 2 weeks of an assessment receiving cough medication, 70% (27 /39) an antihistamine, 26% (10/39) a mucolytic and 15% (6 /39) an oral bronchodilator. At age 22-24 week, infants with reported diarrhea within 2 weeks of an assessment had low use of oral rehydration solutions (ORS) (3/21;14%) and zinc therapy (2/ 21;10%). In this unique observational study, breastfeeding rates of 60% at 6 months were below the Indonesian national target of >75%. Adherence to WHO guidelines for management of ARI and diarrhea was poor, with high use of non-recommended cough medications and oral bronchodilators in the first 6 months of life

Background Mental illness is stigmatized in most of the communities and people with such illness are often subjected to defame. Stigma impairs an individual’s and their caregiver’s physical, social and emotional wellbeing, and health-seeking behavior. Sufficient literature on how often the caregivers of people with mental illness from low and middle-income countries are stigmatized and how they perceive people with mental illness is unavailable. In this study, we examined caregivers’ attitude towards people with mental illness and perceived stigma. Methods We conducted face-to-face interviews with 170 caregivers in an outpatient clinic of a hospital in Nepal using a structured questionnaire. We calculated median and inter-quartile range of the attitude and perceived stigma scores. To assess the correlates, Kruskal Wallis H test and Mann Whitney U test were carried out. Results Overall median score for the domains: attitude (score range: 18–90) and perceived stigma (score range: 12–60) were 42 and 28 respectively, inter-quartile range being 8 each. Attitude score differed significantly by the sex of caregiver (pattitude towards mental illness. Similarly, sex of participant, marital status, educational status, occupation, caregiver’s relation with patient and use of alternative treatment modalities were correlates of perceived stigma. Findings of this study suggest that interventions targeting these high-risk populations might be beneficial to help build a positive attitude and overcome the perceived social stigma. PMID:27336391

Immunization against diseases is one of the most important public health interventions with cost effective means to preventing childhood morbidity, mortality and disability. However, a proportion of children particularly in Africa are not fully immunized with the recommended vaccines. Thus, many children are still susceptible to the Expanded Program on Immunization (EPI) targeted diseases. The objective of this study was to determine the immunization dropout rate and data quality among children aged 12-23 months in Techiman Municipality, Ghana. A cross-sectional cluster survey was conducted among 600 children. Data was collected using semi-structured questionnaire through face-to-face interviews. Before the main data collection, the tools were pre-tested in three different communities in the Municipality. The mothers/caregivers were interviewed, extracted information from the child immunization cards and observation employed to confirm the presence of Bacillus Calmette-Guerin (BCG) scar on each child. Routine immunization data was also extracted from immunization registers and annual reports in the Municipality. I mmunization coverage for each of the fifteen vaccines doses is above 90.0% while full childhood immunized status is 89.5%. Immunization dropout rate was 5.6% (using BCG and Measles as proxy vaccines). This is lower than the 10.0% cutoff point by World Health Organization. However, routine administrative data was characterized by some discrepancies (e.g. > 100.0% immunization coverage for each of the vaccines) and high dropout rate (BCG - Measles = 31.5%). Binary regression was performed to determine predictors of dropout rate. The following were statistically significant: married (OR = 0.31; 95% = CI 0.15-0.62; and p  = 0.001), Christianity (OR = 0.27; 95% CI = 0.13-0.91; and p  dropout. Childhood full immunized status (89.5%) and immunization coverages (>90%) are high while dropout rate is lower than the recommended cutoff point by WHO

Introduction of new private, voluntary immunizations often results in low vaccine uptake among certain sub-groups within the population. Revealing factors associated with underimmunization is crucial in vaccine endorsement and distribution. Our goal was to investigate the effect of child's birth order on private voluntary varicella vaccination. A nested case-control study was conducted on a cohort of 110,902 Israeli children under the age of 5 years. We compared social and demographic factors of immunized and unimmunized participants. Logistic regression models were built to examine the association between birth order and vaccination, controlling for child's age, gender, country of birth, ethnicity, parents' country of birth, area of residence, and socioeconomic status (SES). Ethnicity had the highest association with varicella immunization status. The odds of vaccination in the general Jewish and Ultra-Orthodox Jewish populations were 25.55- (95%CI:20.13;32.42) and 15.04- (95%CI:10.18;22.22) times the odds in Arab population, respectively. Child's birth order was inversely related to vaccination status and presented a nonlinear exposure-response relationship. This relationship was maintained in different ethnicity and SES groups. Child's birth order was associated with vaccination differently in large (> 3 siblings) and small to average-sized sibships (≤ 3 siblings). Other parameters associated with vaccination were child's and parents' country of origin, area of residence and SES. Birth order is an independent risk factor for underimmunization, associated with child's vaccination status beyond economic, social, and demographic parental characteristics.

The disease impact and economic burden of fibromyalgia (FM) are high for patients and society at large. Knowing potential determinants of economic costs may help in reducing this burden. Cognitive appraisals (perceptions) of the illness could affect costs. The present study estimated costs of illness in FM and examined the association between these costs and illness perceptions. Questionnaire data of FM severity (FIQ), illness perceptions (IPQ-R-FM), productivity losses (SF-HLQ) and health care use were collected in a cohort of patients with FM. Costs were calculated and dichotomised (median split). Univariate and hierarchic logistic regression models examined the unique association of each illness perception with 1) health care costs and 2) costs of productivity losses. Covariates were FM severity, comorbidity and other illness perceptions. 280 patients participated: 95% female, mean age 42 (SD=12) years. Annualised costs of FM per patient were €2944 for health care, and €5731 for productivity losses. In multivariate analyses, a higher disease impact (FIQ) and two of seven illness perceptions (IPQ-R-FM) were associated with high health care costs: 1) high scores on 'cyclical timeline' reflecting a fluctuating, unpredictable course and 2) low scores on 'emotional representations', thus not perceiving a connection between fibromyalgia and emotions. None of the variables was associated with productivity losses. Our study indicates that perceiving a fluctuating course and low emotional representation, which perhaps reflects somatic fixation, are associated with health care costs in FM. Future studies should examine whether targeting these illness perceptions results in reduction of costs.

Our team has developed a technological innovation that detects changes in health status that indicate impending acute illness or exacerbation of chronic illness before usual assessment methods or self-reports of illness. We successfully used this information in a 1-year prospective study to alert health care providers so they could readily assess the situation and initiate early treatment to improve functional independence. Intervention participants showed significant improvements (as compared with the control group) for the Short Physical Performance Battery gait speed score at Quarter 3 (p = 0.03), hand grip-left at Quarter 2 (p = 0.02), hand grip-right at Quarter 4 (p = 0.05), and the GAITRite functional ambulation profile score at Quarter 2 (p = 0.05). Technological methods such as these could be widely adopted in older adult housing, long-term care settings, and in private homes where older adults wish to remain independent for as long as possible.

Mycoplasma hyosynoviae causes arthritis in pigs older than 12 weeks. The role of colostrum in protection of piglets against M. hyosynoviae infection is not clear. Our objective was therefore to investigate whether transfer of maternal immunity to piglets was involved in early protection against...... immune response that complements the maternally transferred immune factors. Evident from this study is that the general absence of M. hyosynoviae arthritis in piglets can be ascribed mainly to their immunological status....

Full Text Available Objectives: The objective of this study is to determine the prevalence and sociodemographic correlates for mental illness among inmates at Mukobeko Maximum Security Prison, Zambia. Materials and Methods: A cross sectional study was conducted to assess psychiatric disturbance using a Self-Reported Questionnaire (SRQ20. A cut off point of 7/8 was used. The Chi-square test and Fishers′ exact test were used to determine associations at the 5% significance level, and magnitude of association was estimated using the odds ratio and its 95% confidence interval. Results: Of the 394 inmates in prison, 29.2% had a current mental illness. Gender status was significantly associated with mental illness. Male participants were 35% (odds ratio = 0.65, 95% confidence interval [0.51, 0.82] less likely to have mental illness compared to female participants. Conclusions: The prevalence of mental illness is high in Mukobeko Maximum Security Prison in Zambia. Gender-specific interventions should be designed to reduce the level of mental illness in this prison.

Full Text Available Objective: This preliminary study examined the differences between what was taught during a formal medical education and medical students’ and psychiatry residents’ conceptions of notions regarding the causes and determinants of mental illness. Methods: The authors surveyed 74 medical students and 11 residents via convenience sampling. The survey contained 18 statements which were rated twice based on truthfulness in terms of a participant’s formal education and conception, respectively. Descriptive statistics and a Wilcoxon signed rank test determined differences between education and conception. Results: Results showed that students were less likely to perceive a neurotransmitter imbalance to cause mental illness, as opposed to what was emphasized during a formal medical education. Students and residents also understood the importance of factors such as systemic racism and socioeconomic status in the development of mental illness, which were factors that did not receive heavy emphasis during medical education. Furthermore, students and residents believed that not only did mental illnesses have nonuniform pathologies, but that the Diagnostic and Statistical Manual of Mental Disorders also had the propensity to sometimes arbitrarily categorize individuals with potentially negative consequences. Conclusions: If these notions are therefore part of students’ and residents’ conceptions, as well as documented in the literature, then it seems appropriate for medical education to be further developed to emphasize these ideas.

Full Text Available INTRODUCTION: At a time when a great number of diseases can be prevented by changing one's habits and life style, investigations have focused on understanding what adults and children believe to be desirable health practices and uncovering the factors associated with successful adherence to such practices. For these, causal attributions for health and illness were investigated among 96 Brazilian elementary school students. METHODS: Ninety six subjects, aged 6 to 14, were interviewed individually and their causal attributions were assessed through 14 true-false items (e.g. people stay well [healthy] because they are lucky. The relationship between the children's causal attributions and demographic characteristics were also examined. RESULTS: Overall, the results were consistent with previous researches. "Taking care of oneself" was considered the most important cause of good health. "Viruses and germs" and "lack of self-care" were the most selected causes of illness. Analyses revealed significant relationship between subjects' causal attribution and their age, school grade level, socioeconomic status and gender. CONCLUSIONS: The study findings suggest that there may be more cross-cultural similarities than differences in children's causal attributions for health and illness. Finding ways to help individuals engage in appropriate preventive-maintenance health practices without developing an exaggerated notion that the individuals can control their own health and illness is a challenge which remains to be addressed by further research.

Myxoma virus (MYXV) gained importance throughout the twentieth century because of the use of the highly virulent Standard Laboratory Strain (SLS) by the Australian government in the attempt to control the feral Australian population of Oryctolagus cuniculus (European rabbit) and the subsequent illegal release of MYXV in Europe. In the European rabbit, MYXV causes a disease with an exceedingly high mortality rate, named myxomatosis, which is passively transmitted by biting arthropod vectors. MYXV still has a great impact on European rabbit populations around the world. In contrast, only a single cutaneous lesion, restricted to the point of inoculation, is seen in its natural long-term host, the South-American Sylvilagus brasiliensis and the North-American S. Bachmani. Apart from being detrimental for European rabbits, however, MYXV has also become of interest in human medicine in the last two decades for two reasons. Firstly, due to the strong immune suppressing effects of certain MYXV proteins, several secreted virus-encoded immunomodulators (e.g. Serp-1) are being developed to treat systemic inflammatory syndromes such as cardiovascular disease in humans. Secondly, due to the inherent ability of MYXV to infect a broad spectrum of human cancer cells, the live virus is also being developed as an oncolytic virotherapeutic to treat human cancer. In this review, an update will be given on the current status of MYXV in rabbits as well as its potential in human medicine in the twenty-first century.

This study examined the acute immune and inflammatory responses to exercise in smokers compared to non-smokers, and further, the effect of smoking history on these immune-inflammatory responses. Fifty-four recreationally active males who were either smokers (SM; n = 27) or non-smokers (NS; n = 27) were allocated into either young (YSM, YNS) or middle-aged groups (MSM, MNS) based on smoking status. Participants were matched for fitness and smoking habits and following familiarization and baseline testing, undertook an exercise protocol that involved 40 min of cycle ergometry at 50% of VO2peak. Venous blood was obtained pre- and post- (0 min, 1, and 4 h) exercise to measure circulating leukocytes and inflammatory markers interleukin (IL)-6, IL-1β, IL-1ra, and monocyte chemoattractant protein-1 (MCP-1). Compared to MNS, MSM showed elevated basal concentrations of MCP-1, which were increased with a longer smoking history (P exercise, YSM demonstrated an amplified IL-6 response from immediately- to 1 h-post compared to YNS. Furthermore, IL-1ra in YSM was elevated above that of YNS across all time points (P exercise leukocyte response was greater in MSM compared to YSM and non-smokers (P smoking history (~15 years). Furthermore, the differences in exercise-induced inflammatory responses noted in YSM may be indicative tobacco smoke exposure priming circulating leukocytes to amplify inflammatory responses.

Achieving gender equality in education is an important development goal. We tested the hypothesis that the gender gap in adolescent education is accentuated by illnesses among young children in the household. Using Demographic and Health Surveys on 41 821 households in 38 low- and middle-income countries, we used linear regression to estimate the difference in the probability adolescent girls and boys were in school, and how this gap responded to illness episodes among children gender gap in education, we assessed the relationship between the gender gap and national immunization coverage. In our sample of 120 708 adolescent boys and girls residing in 38 countries, girls were 5.08% less likely to attend school than boys in the absence of a recent illness among young children within the same household (95% confidence interval [CI], 5.50%-4.65%). This gap increased to 7.77% (95% CI, 8.24%-7.30%) and 8.53% (95% CI, 9.32%-7.74%) if the household reported 1 and 2 or more illness episodes, respectively. The gender gap in schooling in response to illness was larger in households with a working mother. Increases in child vaccination rates were associated with a closing of the gender gap in schooling (correlation coefficient = 0.34, P = .02). Illnesses among children strongly predict a widening of the gender gap in education. Investments in early childhood health may have important effects on schooling attainment for adolescent girls.

Parental care, while increasing parental fitness through offspring survival, also bears cost to the care-giving parent. Consequentially, trade offs between parental care and other vitally important traits, such as the immune system seem evident. In co-occurring phases of parental care and immunological challenges negative consequences through a resource allocation trade off on both the parental and the offspring conditions can be predicted. While the immune system reflects parental stress conditions, parental immunological investments also boost offspring survival via the transfer of immunological substances (trans-generational immune priming). We investigated this relationship in the mouthbrooding East African cichlid Astotatilapia burtoni. Prior to mating, females were exposed to an immunological activation, while others remained immunologically naïve. Correspondingly, the immunological status of females was either examined directly after reproduction or after mouthbrooding had ceased. Offspring from both groups were exposed to immunological challenges to assess the extent of trans-generational immune priming. As proxy for immune status, cellular immunological activity and gene expression were determined. Both reproducing and mouthbrooding females allocate their resources towards reproduction. While upon reproduction the innate immune system was impeded, mouthbrooding females showed an attenuation of inflammatory components. Juveniles from immune challenged mouthbrooding females showed downregulation of immune and life history candidate genes, implying a limitation of trans-generational plasticity when parents experience stress during the costly reproductive phase. Our results provide evidence that both parental investment via mouthbrooding and the rise of the immunological activity upon an immune challenge are costly traits. If applied simultaneously, not only mothers seem to be impacted in their performance, but also offspring are impeded in their ability to

While agreement is growing that mental illness burdens the North American economy, how it impacts productivity--particularly compared to physical illness--is unclear. Hypothesizing that lost work days are only the tip of the iceberg, we also examined the association of mental and chronic physical illness with partial work days and days requiring extra effort to function. Data from 4225 employed individuals, aged 18-54, were analyzed. These were a subset of respondents to the Ontario Health Survey's Mental Health Supplement, a 1990/91 epidemiologic survey of households across Ontario, Canada. Psychiatric disorder was assessed using the University of Michigan' modification of WHO's Composite International Diagnostic Interview (UM-CIDI). Similar to US reports, professional/managerial groups had lower rates of affective and anxiety disorders and fewer disability days compared to the rest of the workforce. However, no single occupational group was consistently at greater risk for either physical or psychiatric problems. Even after accounting for sociodemographic characteristics and work conditions, mental and physical status had clear, but different, impacts on productivity. Physical conditions alone had a fairly constant effect across all types of disability days and were the largest contributor to total work day loss. They also significantly impacted partial and extra effort days but were far less important than conditions involving a mental disorder. Respondents with mental health problems, either alone or in combination with physical illnesses, appeared more likely to go to work but to require greater effort to function. WHO projects that mental illness will become the second most important cause of global disease burden in the next century. Our findings suggest that among working individuals, it affects productivity more subtly than does physical illness. However, with an estimated eight percent of Ontario's workforce experiencing more than two months annually of

Cytokines and the neurodevelopmental basis of mental illness

Directory of Open Access Journals (Sweden)

Udani eRatnayake

2013-10-01

Full Text Available Epidemiological studies suggest that prenatal exposure to different types of viral or bacterial infections may be associated with similar outcomes; i.e., an increased risk of mental illness disorders in the offspring. Infections arising from various causes have similar debilitating effects in later life, suggesting that the exact pathogen may not be the critical factor in determining the neurological and cognitive outcome in the offspring. Instead, it is thought that response of the innate immune system, specifically the increased production of inflammatory cytokines, may be the critical mediator in altering fetal brain development pre-disposing the offspring to mental illness disorders later in life. Inflammatory cytokines are essential for normal brain development. Factors such as the site of cytokine production, a change in balance between anti- and pro- inflammatory cytokines, placental transfer of cytokines, the effects of cytokines on glial cells, and the effects of glucocorticoids are important when evaluating the impact of maternal infection on fetal brain development. Although it is clear that cytokines are altered in the fetal brain following maternal infection, further evidence is required to determine if cytokines are the critical factor that alters the trajectory of brain development, subsequently leading to postnatal behavioural and neurological abnormalities.

The Role of the Immune System in Metabolic Health and Disease.

2017-03-07

In addition to the immune system's traditional roles of conferring anti-infectious and anti-neoplastic protection, it has been recently implicated in the regulation of systemic metabolic homeostasis. This cross-talk between the immune and the metabolic systems is pivotal in promoting "metabolic health" throughout the life of an organism and plays fundamental roles in its adaptation to ever-changing environmental makeups and nutritional availability. Perturbations in this intricate immune-metabolic cross-talk contribute to the tendency to develop altered metabolic states that may culminate in metabolic disorders such as malnutrition, obesity, type 2 diabetes mellitus (T2DM), and other features of the metabolic syndrome. Regulators of immune-metabolic interactions include host genetics, nutritional status, and the intestinal microbiome. In this Perspective, we highlight current understanding of immune-metabolism interactions, illustrate differences among individuals and between populations in this respect, and point toward future avenues of research possibly enabling immune harnessing as means of personalized treatment for common metabolic disorders.

Immune Modulation by Vitamin D and Its Relevance to Food Allergy

Directory of Open Access Journals (Sweden)

Noor H. A. Suaini

2015-07-01

Full Text Available Apart from its classical function in bone and calcium metabolism, vitamin D is also involved in immune regulation and has been linked to various cancers, immune disorders and allergic diseases. Within the innate and adaptive immune systems, the vitamin D receptor and enzymes in monocytes, dendritic cells, epithelial cells, T lymphocytes and B lymphocytes mediate the immune modulatory actions of vitamin D. Vitamin D insufficiency/deficiency early in life has been identified as one of the risk factors for food allergy. Several studies have observed an association between increasing latitude and food allergy prevalence, plausibly linked to lower ultraviolet radiation (UVR exposure and vitamin D synthesis in the skin. Along with mounting epidemiological evidence of a link between vitamin D status and food allergy, mice and human studies have shed light on the modulatory properties of vitamin D on the innate and adaptive immune systems. This review will summarize the literature on the metabolism and immune modulatory properties of vitamin D, with particular reference to food allergy.

In vivo immune signatures of healthy human pregnancy: Inherently inflammatory or anti-inflammatory?

Directory of Open Access Journals (Sweden)

Caroline Graham

Full Text Available Changes in maternal innate immunity during healthy human pregnancy are not well understood. Whether basal immune status in vivo is largely unaffected by pregnancy, is constitutively biased towards an inflammatory phenotype (transiently enhancing host defense or exhibits anti-inflammatory bias (reducing potential responsiveness to the fetus is unclear. Here, in a longitudinal study of healthy women who gave birth to healthy infants following uncomplicated pregnancies within the Canadian Healthy Infant Longitudinal Development (CHILD cohort, we test the hypothesis that a progressively altered bias in resting innate immune status develops. Women were examined during pregnancy and again, one and/or three years postpartum. Most pro-inflammatory cytokine expression, including CCL2, CXCL10, IL-18 and TNFα, was reduced in vivo during pregnancy (20-57%, p<0.0001. Anti-inflammatory biomarkers (sTNF-RI, sTNF-RII, and IL-1Ra were elevated by ~50-100% (p<0.0001. Systemic IL-10 levels were unaltered during vs. post-pregnancy. Kinetic studies demonstrate that while decreased pro-inflammatory biomarker expression (CCL2, CXCL10, IL-18, and TNFα was constant, anti-inflammatory expression increased progressively with increasing gestational age (p<0.0001. We conclude that healthy resting maternal immune status is characterized by an increasingly pronounced bias towards a systemic anti-inflammatory innate phenotype during the last two trimesters of pregnancy. This is resolved by one year postpartum in the absence of repeat pregnancy. The findings provide enhanced understanding of immunological changes that occur in vivo during healthy human pregnancy.

The immune status of mice has been assessed by the whole complex of data. The permanent action of low-level radiation has been shown to suppress considerably the rate of reactions of the delayed-type hypersensitivity and graft-versus host disease, as well as NK and specific cytolytic T-lymphocyte activity. The dynamics of accumulation and the levels of antibodies in the serum, lung and trachea extracts are virtually invariable. The resistance of experimental animals to influenza is lower than that of non-irradiated mice of the same line and age. The data obtained indicate that the immune disturbances revealed are connected not only with the alteration of lymphoid cell populations, but also with the alteration of the immune regulation mechanisms

CD8+ T cells provide immune protection against murine disseminated endotheliotropic Orientia tsutsugamushi infection.

2017-07-01

Full Text Available Scrub typhus, caused by a Gram-negative obligately intracellular coccobacillus, Orientia tsutsugamushi, is a long neglected but important tropical disease. Orientia tsutsugamushi causes illness in one million people each year, and 1 billion people are at risk. Without appropriate diagnosis and treatment, the disease can cause severe multiorgan failure with a case fatality rate of 7-15%. The current gaps in knowledge of immunity include the unknown mechanisms of host immunity to O. tsutsugamushi. Using an intravenous (i.v. disseminated infection mouse model, we observed that more CD8+ T cells than CD4+ T cells were present in the spleen of infected mice at 12 dpi. We also determined that Treg cells and the proportion of T cells producing IL-10 were significantly increased from 6 dpi, which correlated with the onset of illness, body weight loss, and increased bacterial loads. We further studied CD8-/-, MHC I-/- and wild type control (WT C57BL/6J mice to determine the importance of CD8+ T cells and MHC I molecules. After infection with an ordinarily sub-lethal dose of O. tsutsugamushi, all CD8-/- and MHC I-/- mice were moribund between 12 and 15 dpi, whereas all WT mice survived. Bacterial loads in the lung, kidney, liver and spleen of CD8-/- and MHC I-/- mice were significantly greater than those in WT mice. Interferon-γ (IFN-γ and granzyme B mRNA levels in the liver of CD8-/- and MHC I-/- mice were significantly greater than in WT mice. In addition, more severe histopathologic lesions were observed in CD8-/- mice. Finally, adoptive transfer confirmed a major role of immune CD8+ T cells as well as a less effective contribution by immune CD8 T cell-depleted splenocytes in protection against O. tsutsugamushi infection. These studies demonstrated the critical importance of CD8+ T cells in the host immune response during O. tsutsugamushi infection.

This study assessed children's awareness for adult HIV-associated symptoms and illnesses using a verbal assessment tool by analysing inter-rater reliability between adult-child dyads. This study also evaluated sociodemographic and household characteristics associated with child awareness of adult symptomatic HIV. A cross-sectional survey using a representative community sample of adult-child dyads (N=2477 dyads) was conducted in KwaZulu-Natal, South Africa. Analyses focused on a subsample (n=673 adult-child dyads) who completed verbal assessment interviews for symptomatic HIV. We used an existing validated verbal autopsy approach, originally designed to determine AIDS-related deaths by adult proxy reporters. We adapted this approach for use by child proxy reporters for reporting on HIV-associated symptoms and illnesses among living adults. Analyses assessed whether children could reliably report on adult HIV-associated symptoms and illnesses and adult provisional HIV status. Adult-child pairs concurred above the 65th percentile for 9 of the 10 HIV-associated symptoms and illnesses with sensitivities ranging from 10% to 100% and specificities ranging from 20% to 100%. Concordant reporting between adult-child dyads for the adult's provisional HIV status was 72% (sensitivity=68%, specificity=73%). Children were more likely to reliably match adult's reports of provisional HIV status when they lived in households with more household members, and households with more robust socioeconomic indicators including access to potable water, food security and television. Children demonstrate awareness of HIV-associated symptoms and illnesses experienced by adults in their household. Children in households with greater socioeconomic resources and more household members were more likely to reliably report on the adult's provisional HIV status.

Full Text Available Effectiveness of High Dose Vitamin A Supplementation on The Recovery Rate and Immune Status of Underfive Children Suffering From Tuberculosis.Tuberculosis (TB, the infectious disease, is still one of the health problems in Indonesia. TB does not just make the people sick physically, but also interfere the immunity. As we have known that vitamin A can improve the immunity. The aimed of this randomized double blind study was to know the effect of high dose vitamin A on the improvement, immune status and the relationship between vitamin A and immune status in TB. Sixtyfive underfive children were selected from the Pediatrics Wards for out patient in Salak and Clsarua Hospital. They were grouped into 11 treatment group who received standard regimen therapy for TB plus high dose vitamin A in each month for 6 months and 21 control group who received the same TB regimen plus placebo also in each month for 6 months. Data on physical examination, weight, height, hemoglobin (Hb, hematocrit (Ht, blood sedimen rate (BSR, serum vitamin A, immunoglobulin G (IgG to TB, chest X ray (CXR and food consumption were collected before and after (6 months intervention. Information on morbidity and socioeconomic also were recorded. To evaluate the degree of improvement, score on nutritional status, BSR and CXR were made. The results showed that after 6 month there were improvement in anthropometry status, morbidity rate, Hb, Ht, BSR, IgG and CXR for both groups. The treatment group was improved in 7.2% subjects meanwhile the control group was improved in 58% subjects. Analysis for scoring improvement showed that the treatment group had better improvement 2,4 times than the control group. The conclusions are that the high dose vitamin A has a positive effect on the recovery and immune status of underfive children suffering TB. This study suggests to give high dose vitamin A to the regimen therapy for TB in children to get better results.Keywords: tuberculosis, vitamin A

Background: In Pakistan Routine Immunization coverage has been reported to be significantly low due to multiple factors that results in high number of deaths in children under 5. This study was conducted to assess the effectiveness of integrating Community Services to improve Routine immunization coverage in rural district of Pakistan. Methods: A quasi-experimental study with control and intervention arms was conducted in government Basic Health units catchment population of Panjgur by interviewing household head/Fathers. Total 234 household head including fathers were interviewed during this baseline survey. Community service model was used for to increase routine immunization coverage at catchment area of Basic Health unit (BHU) in intervention group while routine services were given in control BHU. Results: 230 parents completed the questionnaire during the end line after three months of intervention. There were no significant differences found between two groups at baseline but after the intervention, there was statistically significance difference (<0.05) between both groups knowledge and practices regarding routine immunization. Moreover, there was no statistically significant difference in control group reported (>0.05) after the intervention period. Overall immunization status after intervention where fully immunization status in intervention group after intervention was 88.8% as compared to control group after intervention was 13.6% for partial immunization status in intervention group after intervention was 11.1% as compared to control group after intervention was 81.1 for the Non-Immunization status in intervention group after intervention was 0% as compared to control group after intervention was 5.1%. Conclusions: Community Service Model has significantly improved the Knowledge and Practices among households/parents of children under 5 in the intervention arm. (author)

Full Text Available Abstract Background Gastrointestinal illness is an important global public health issue, even in developed countries, where the morbidity and economic impact are significant. Our objective was to evaluate the demographic determinants of acute gastrointestinal illness in Canadians. Methods We used data from two population-based studies conducted in select communities between 2001 and 2003. Together, the studies comprised 8,108 randomly selected respondents; proxies were used for all respondents under 12 years and for respondents under 19 years at the discretion of the parent or guardian. Using univariate and multivariate logistic regression, we evaluated the following demographic determinants: age, gender, cultural group, and urban/rural status of the respondent, highest education level of the respondent or proxy, number of people in the household, and total annual household income. Two-way interaction terms were included in the multivariate analyses. The final multivariate model included income, age, gender, and the interaction between income and gender. Results After adjusting for income, gender, and their interaction, children under 10 years had the highest risk of acute gastrointestinal illness, followed by young adults aged 20 to 24 years. For males, the risk of acute gastrointestinal illness was similar across all income levels, but for females the risk was much higher in the lowest income category. Specifically, in those with total annual household incomes of less than $20,000, the odds of acute gastrointestinal illness were 2.46 times higher in females than in males. Conclusion Understanding the demographic determinants of acute gastrointestinal illness is essential in order to identify vulnerable groups to which intervention and prevention efforts can be targeted.

Streptococcus pneumoniae is a principal cause of serious illness, including bacteremia, meningitis, and pneumonia, worldwide. Pneumococcal immunization is proven to reduce morbidity and mortality in high-risk adult and elderly populations. Current pneumococcal vaccination practices are suboptimal in part because of recommendation complexity, the high cost of provider-driven immunization interventions, and outreach methods that are not patient-centric. These barriers are amplified within the safety net. This paper identifies efforts by the Los Angeles County Department of Health Services to increase pneumococcal immunization rates for adult indigent patient populations. A 4-part approach will be used to increase vaccination rates: (1) protocol driven care, (2) staff education, (3) electronic identification of eligible patients, and (4) automated patient outreach and scheduling. The proposed analytics plan and potential for scalability are described. (Population Health Management 2016;19:240-247).

Trauma: the role of the innate immune system

2006-05-01

Full Text Available Abstract Immune dysfunction can provoke (multiple organ failure in severely injured patients. This dysfunction manifests in two forms, which follow a biphasic pattern. During the first phase, in addition to the injury by trauma, organ damage is caused by the immune system during a systemic inflammatory response. During the second phase the patient is more susceptible for sepsis due to host defence failure (immune paralysis. The pathophysiological model outlined in this review encompasses etiological factors and the contribution of the innate immune system in the end organ damage. The etiological factors can be divided into intrinsic (genetic predisposition and physiological status and extrinsic components (type of injury or "traumaload" and surgery or "intervention load". Of all the factors, the intervention load is the only one which, can be altered by the attending emergency physician. Adjustment of the therapeutic approach and choice of the most appropriate treatment strategy can minimize the damage caused by the immune response and prevent the development of immunological paralysis. This review provides a pathophysiological basis for the damage control concept, in which a staged approach of surgery and post-traumatic immunomonitoring have become important aspects of the treatment protocol. The innate immune system is the main objective of immunomonitoring as it has the most prominent role in organ failure after trauma. Polymorphonuclear phagocytes and monocytes are the main effector-cells of the innate immune system in the processes that lead to organ failure. These cells are controlled by cytokines, chemokines, complement factors and specific tissue signals. The contribution of tissue barrier integrity and its interaction with the innate immune system is further evaluated.

There is an increased prevalence of physical illness and poor lifestyle in patients with chronic schizophrenia. It is unclear whether these are present at the onset of psychosis or develop over the course of illness. We aimed to establish whether patients experiencing their first episode of psychosis have worse physical health and lifestyle than community controls without psychosis. Eighty-nine patients with new onset illness were compared to age and sex matched controls for self-reported physical illness and cardiovascular and respiratory risk factors. Patients reported more physical health complaints, mainly respiratory, compared with age and gender matched controls (odds ratio 2.85, 95% confidence interval 1.2-6.7). Patients were more likely to be cigarette smokers (1.82, 95% CI 1.0-3.3) and eat a fast food diet (1.04, 95% CI 1.0-1.1), but these differences were accounted for by patients' unemployment status. Some risk factors for physical health problems are present at the onset of psychosis, but these may be explained by unemployment.

The previous studies reported Type D was associated with poor quality of life (QoL), increased psychological distress, and impaired health status in cardiac patients. The aim of this study is to assess the relationships among Type D personality, illness perception, social support, and investigate the impact of Type D personality on QoL in continuous ambulatory peritoneal dialysis (CAPD) patients. Type D personality was assessed by the Chinese 14-item Type D Personality Scale (DS14). Illness perceptions were assessed using the Chinese version of the Brief Illness Perception Questionnaire (B-IPQ). Social support status was assessed by the well-validated social support rating scale (SSRS). Patients' QoL was assessed by using Medical Outcomes Short Form 36 (SF-36), respectively. The Type Ds had significantly lower objective support score (8.18 ± 2.56 vs. 9.67 ± 3.28, p = 0.0001), subjective support score (6.71 ± 2.0 vs. 7.62 ± 1.93, p = 0.0001) and utilization of social support score (6.76 ± 2.0 vs. 7.61 ± 1.94, p = 0.0001) than that of the non-type Ds. Type Ds believed their illness had much more serious consequences (7.67 ± 2.64 vs. 6.27 ± 3.45, p illness (6.65 ± 2.54 vs. 7.31 ± 2.36, p = 0.023). Significant differences were found between Type Ds and non-Type Ds in PCS (40.53 ± 6.42 vs. 48.54 ± 6.21 p mental component score (MCS) (r = -0.31, p social support (r = -0.24, p illness perceptions, social support and QoL in CAPD patients. The worse illness perceptions and lower social support level therefore represent possible mechanisms to explain the link between Type D and poor QoL in CAPD patients.

Pandemic influenza viruses often cause severe disease in middle-aged adults without preexistent co-morbidities. The mechanism of illness associated with severe disease in this age group is not well understood1–10. Here, we demonstrate preexisting serum antibody that cross-reacts with, but does not protect against 2009 H1N1 influenza virus in middle-aged adults. Non-protective antibody is associated with immune complex(IC)-mediated disease after infection. High titers of serum antibody of low avidity for H1-2009 antigen, and low avidity pulmonary ICs against the same protein were detected in severely ill patients. Moreover, C4d deposition - a sensitive marker of complement activation mediated by ICs- was present in lung sections of fatal cases. Archived lung sections from adults with confirmed fatal influenza 1957 H2N2 infection revealed a similar mechanism of illness. These observations provide a novel biological mechanism for the unusual age distribution of severe cases during influenza pandemics. PMID:21131958

Effective immunization campaigns can be designed by determining which persuasion strategy is most effective in attracting the attention of mothers of preschoolers. The authors assess the impact of three persuasional strategies: fear-arousal, motherhood-arousal, and rational messages, on mothers of preschoolers who are late for their immunizations. The fear-arousal message was found to be most effective, followed by the motherhood-arousal, and then the rational message, in attracting mothers' attention to their child's immunization status.

The main objective of this study was to evaluate treatment adherence to statin and health-related quality of life (QOL) in Lebanese patients with dyslipidemia. Secondary objectives were to examine associations between treatment adherence, QOL, treatment satisfaction, and illness perception. This cross-sectional study, conducted in 20 community pharmacies from all districts of Lebanon between August 2016 and April 2017, enrolled 247 adult patients taking any statin. The mean age of the participants was 52.63 ± 11.92 years (57.5% males); the mean duration of treatment with a statin was 59.72 months. A significant association was found between adherence and marital status ( P salary, the marital status, the educational level, smoking cigarettes or waterpipes, and drinking alcohol were all associated with the Illness Perception Questionnaire scores ( P < 0.0001 for all variables). Secondary level of education (β = 13.43), smoking more than 3 waterpipes per week (β = 14.06), global satisfaction score (β = 0.32), convenience score (β = 0.29), and effectiveness score (β = 0.27) would significantly increase the adherence score. Smoking more than 15 cigarettes per day (β = -11.15) and a divorced status (β = -14.81) would however significantly decrease the adherence score. Significant associations were found between the illness perception score, the QOL domains, and the satisfaction domains ( P < .05 for all variables). This study showed that global satisfaction with treatment, convenience, and effectiveness are important factors that increase treatment adherence. Patient adherence results in patient satisfaction and improved QOL and is an important criterion for achieving desired therapeutic outcomes.

Full Text Available Objective　To investigate the use of enteral immune nutrition preparation in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD, regard its efficacy in improving nutritional status, and its influence on immunity and the status of acute inflammatory reaction of the patients. Methods　Sixty-two AECOPD patients requiring mechanical ventilation in ICU of our hospital were randomly divided into two groups: immune nutrition group [study group, n=32, receiving Ruineng (a product of Huarui Pharmaceutical Ltd., which contained essential fatty acids, Omega-3 fatty acids, and energy 1.3 kcal/ml] and conventional nutrition group (control group, n=30, receiving the hospital self-made homogenized diet with 1.2 kal/ml. Patients in the two groups took enteral nutrition of equal calorie, and it was given by nasointestinal tube. On the day of admission and the 14th and 18th after admission, venous blood was obtained for the determination of serum albumin, prealbumin, transferrin, C reactive protein (CRP, tumor necrosis factor-α (TNF-α, and interleukin-6 (IL-6. At the same time upper arm muscle circumference (MAMC was measured at the bed side. The 14-day off-respirator rate and mechanical ventilation time within 28 days were compared between the two groups. Results　The 14-day off-respirator rate was higher in study group than in control group (P0.05. Conclusions　Compared with homogenized diet, immune enteral nutrition could better improve the nutritional status and immune function, lower the acute inflammatory response level, increase the success rate of early off-respirator in AECOPD patients, therefore, enteral immune nutrition preparation is a better nutrition support solution for AECOPD.

Critically ill patients are at high risk to suffer from sepsis, even in the absence of an initial infectious source, but the molecular mechanisms for their increased sepsis susceptibility, including a suppressed immune system, remain unclear. Although microbes and pathogen-associated molecular pattern are accepted inducers of sepsis and septic immunosuppression, the role of endogenous Toll-like receptor (TLR) ligands, such as mitochondrial DNA (mtDNA), in altering the immune response is unknown. Mitochondrial DNA serum concentrations of the mitochondrial genes D-Loop and adenosine triphosphatase 6 were determined (quantitative polymerase chain reaction) in 165 septic patients and 50 healthy volunteers. Furthermore, cytotoxic T-cell activity was analyzed in wild-type and TLR9 knockout mice, with/without previous mtDNA administration, followed by injection of an ovalbumin-expressing adenoviral vector. Mitochondrial DNA serum concentrations were increased in septic patients (adenosine triphosphatase 6, 123-fold; D-Loop, 76-fold, P < 0.0001) compared with volunteers. Furthermore, a single mtDNA injection caused profound, TLR9-dependent immunosuppression of adaptive T-cell cytotoxicity in wild-type but not in TLR9 knockout mice and evoked various immunosuppressive mechanisms including the destruction of the splenic microstructure, deletion of cross-presenting dendritic cells, and up-regulation of programmed cell death ligand 1 and indoleamine 2,3-dioxygenase. Several of these findings in mice were mirrored in septic patients, and mtDNA concentrations were associated with an increased 30-day mortality. The findings of this study imply that mtDNA, an endogenous danger associated molecular pattern, is a hitherto unknown inducer of septic immunoparalysis and one possible link between initial inflammation and subsequent immunosuppression in critically ill patients.

To determine which types of vaccine recommendations were accepted and acted upon by patients after an immunization check-up at a pharmacist-provided employee health screening, and to evaluate if there was a difference between influenza and non-influenza vaccines. Retrospective, observational. Supermarket chain. Employees and covered spouses. Immunization check-up. Acceptance rate of immunization recommendation. This retrospective observational study evaluated the impact of an immunization check-up in individuals who participated in one of the 252 pharmacist-provided health screenings in central Virginia in 2015. All employee health screenings were completed from July 1, 2015, to September 30, 2015. Because immunization status was assessed 6 months after each person received his or her health screening, data were collected from January 1, 2016, to March 30, 2016, and analyzed to collect the number and type of vaccines recommended during the immunization check-up. Each eligible participant's profile was evaluated to determine if he or she received the vaccines at any Kroger pharmacy within 6 months. Patient identifiers were not collected; however, demographics including age, relevant disease state history, and smoking status were collected with immunization recommendations and uptake. Data were analyzed with the use of descriptive statistics. A total of 349 immunization recommendations were made, including 248 influenza; 42 pneumococcal polysaccharide (PPSV23); 40 tetanus, diphtheria, and pertussis (Tdap); 12 herpes zoster; 4 pneumococcal conjugate (PCV13); and 3 hepatitis B. Both influenza and PCV13 had acceptance rates of 50%, and herpes zoster, Tdap, hepatitis B, and PPSV23 had 42%, 35%, 33%, and 24% acceptance rates, respectively. Influenza recommendations had a 50% acceptance rate compared with a 32% acceptance rate of non-influenza recommendations (P = 0.002). An immunization check-up performed at a pharmacist-provided employee health screening can lead to

To assess community awareness of childhood immunizations and intent to immunize children after a social marketing immunization campaign. We used 2 interviewer-assisted street-intercept surveys to evaluate awareness of childhood immunizations and intent to immunize low-income children. The "Take Control! Immunize" social marketing campaign was developed using a community-based participatory research approach and used billboards, flyers, and various "walking billboard" (eg, backpacks, pens) to deliver immunization messages in the community settings. Over 85% of community members recalled the "Take Control! Immunize" message. Almost half of those who saw the immunization message indicated that the message motivated them to act, including getting their children immunized or calling their physician to inquire about their children's immunizations status. All respondents indicated that immunizations were important for children and that they were likely or very likely to immunize their children. Respondents who reported that "Take Control!" messages motivated them to act in the first intercept survey were significantly more likely than those in the second intercept to report being likely or very likely to immunize their children. Culturally appropriate social marketing immunization messages in targeted urban settings can increase parental awareness and behavioral intention to immunize children.

Full Text Available Objective: to investigate the impact of incorporation of cycloferon into a therapy regimen on the efficiency of treatment for acute respiratory viral infections (ARVI in frequently ill children. Subjects and methods. The results of treatment were analyzed in 117 children divided into three groups according to the therapy regimen. Thus, symptomatic and local antiviral therapies (interferon nasal ointment and viferon suppositories were prescribed to all the children; furthermore, Group 1 (control used antibiotic therapy; Group 2 (Comparison Group 1 took antibiotics and cycloferon (tablets, and Group 3 (Comparison Group 2 had Cycloferon. Results: At the beginning of treatment, there was a reduction in interferon-a and interferon-y values with preserved serum interferon levels, suggesting the diminished compensatory responses ensuring antiviral protection. Analysis of the immune status revealed that virtually half of the children exhibited activation of compensatory mechanisms (stimulation of CD4+ and CD8+ production and an increase in NST test activity, one third displayed a disturbance (decreases in CD4+, CDlfrf, IgA, and NST test activity. After treatment, interferonogenesis was recovered in the majority (86,7% of the patients taking Cycloferon, in 74,1% of those who had a treatment regimen containing cycloferon and antibiotics, and only in 47,1 % of those who received antibiotics. Comparison of the immunological indicators during therapy with antibiotics alone or in combination with cycloferon demonstrated a more noticeable and balanced response to the latter: the normalized CD4+ and CD8+ values in the patients on antibiotic therapy was 8,9 and 5,8%, respectively, and 11,1 % in those who received antibiotics and cycloferon. Conclusion. Incorporation of cycloferon into ARVI treatment regimens for frequently ill patients has the positive effect on immunological indicators, which shows itself as recovery of initially diminished interferonogenesis

Although bariatric surgery has become a recognized treatment for obesity, its utility among patients with severe psychiatric disorders has not been extensively studied. A few studies have reported similar weight loss outcomes in these patients, but psychiatric status after bariatric surgery has been studied only minimally, and it is unknown if exacerbation of the mental illness affects weight loss. The aim of this study was to shed greater light on the issue of serious mental illness and bariatric surgery. Specifically, do patients with a diagnosis of schizophrenia, bipolar I, and bipolar II have poorer weight loss outcomes postbariatric surgery than the general bariatric surgery population? Also, do patients with these diagnoses experience an exacerbation of psychiatric symptoms after bariatric surgery, and if so, is the exacerbation of these disorders linked to poorer weight loss results? Midwest university medical center. A medical record review of approximately 1500 bariatric patients in a Midwest university medical center was conducted to identify those patients with diagnoses of schizophrenia, bipolar I, and bipolar II. Information was gathered on bariatric surgery outcomes and changes in psychiatric status postsurgery. Eighteen patients were identified as undergoing bariatric surgery and having a diagnosis of schizophrenia, bipolar I, or bipolar II. Weight loss in this group was significant and comparable to expected outcomes of absolute weight lost, changes in body mass index, and percentage excess weight loss for patients in the typical bariatric population. Postsurgery psychiatric status was known on 10 patients. All 10 patients experienced some exacerbation of psychiatric problems yet weight loss outcomes were still as expected. Bariatric surgery is a viable obesity treatment option for patients with schizophrenia, bipolar I, and bipolar II disorders. Symptom exacerbations occurred postsurgery, although it is not clear if these were due to the surgery or

Manipulation of Innate and Adaptive Immunity by Staphylococcal Superantigens

Full Text Available Staphylococcal superantigens (SAgs constitute a family of potent exotoxins secreted by Staphylococcus aureus and other select staphylococcal species. SAgs function to cross-link major histocompatibility complex (MHC class II molecules with T cell receptors (TCRs to stimulate the uncontrolled activation of T lymphocytes, potentially leading to severe human illnesses such as toxic shock syndrome. The ubiquity of SAgs in clinical S. aureus isolates suggests that they likely make an important contribution to the evolutionary fitness of S. aureus. Although the apparent redundancy of SAgs in S. aureus has not been explained, the high level of sequence diversity within this toxin family may allow for SAgs to recognize an assorted range of TCR and MHC class II molecules, as well as aid in the avoidance of humoral immunity. Herein, we outline the major diseases associated with the staphylococcal SAgs and how a dysregulated immune system may contribute to pathology. We then highlight recent research that considers the importance of SAgs in the pathogenesis of S. aureus infections, demonstrating that SAgs are more than simply an immunological diversion. We suggest that SAgs can act as targeted modulators that drive the immune response away from an effective response, and thus aid in S. aureus persistence.

This paper is a report of a concept analysis of illness blogs and their relevance to nursing research on communication during illness. Blogs are being used by patients and family members to describe the experience of illness, but very little is known about this phenomenon. Seventeen English language databases and one Internet search engine were searched from 1990 to 2007 using the truncated term 'blog*'. Specific illness terms together with 'blog*', for example, blog* and diabetes; and blog* and cancer, were used to expand the search. Reports were included if they were of qualitative or quantitative research that included a definition of blogs or blogging and some identification or description of blog uses pertinent to the discipline. Specific emphasis was placed on blog use by individuals coping with illness experiences. 'Meta' writings by authors about their own blogging intentions and experiences were excluded. An illness blog is the online expression of the narrative of illness. Theoretical and operational definitions, defining attributes, uses, antecedents and consequences were developed. The literature search returned 45 works from 17 disciplines referring to the definition and uses of blogging. Support is offered from the review of literature and analysis of the concept for the development of a theory of online communication during illness. Reading and incorporating illness blogs into care will enhance patient-provider relationships. Analysis of the narratives being created online about the illness experience will contribute significantly to nursing's body of knowledge.

Sjögren's syndrome is a chronic illness manifested characteristically by immune injury to the salivary and lacrimal glands, resulting in dry mouth/eyes. Anti-Ro [Sjögren's syndrome antigen A (SSA)] and anti-La [Sjögren's syndrome antigen B (SSB)] autoantibodies are found frequently in Sjögren's subjects as well as in individuals who will go on to develop the disease. Immunization of BALB/c mice with Ro60 peptides results in epitope spreading with anti-Ro and anti-La along with lymphocyte infiltration of salivary glands similar to human Sjögren's. In addition, these animals have poor salivary function/low saliva volume. In this study, we examined whether Ro-peptide immunization produces a Sjögren's-like illness in other strains of mice. BALB/c, DBA-2, PL/J, SJL/J and C57BL/6 mice were immunized with Ro60 peptide-274. Sera from these mice were studied by immunoblot and enzyme-linked immunosorbent assay for autoantibodies. Timed salivary flow was determined after pharmacological stimulation, and salivary glands were examined pathologically. We found that SJL/J mice had no immune response to the peptide from Ro60, while C57BL/6 mice produced antibodies that bound the peptide but had no epitope spreading. PL/J mice had epitope spreading to other structures of Ro60 as well as to La, but like C57BL/6 and SJL/J had no salivary gland lymphocytic infiltration and no decrement of salivary function. DBA-2 and BALB/c mice had infiltration but only BALB/c had decreased salivary function. The immunological processes leading to a Sjögren's-like illness after Ro-peptide immunization were interrupted in a stepwise fashion in these differing mice strains. These data suggest that this is a model of preclinical disease with genetic control for epitope spreading, lymphocytic infiltration and glandular dysfunction. Published 2013.

Full Text Available BACKGROUND: Dengue illness causes 50-100 million infections worldwide and threatens 2.5 billion people in the tropical and subtropical regions. Little is known about the disease burden and economic impact of dengue in higher resourced countries or the cost-effectiveness of potential dengue vaccines in such settings. METHODS AND FINDINGS: We estimate the direct and indirect costs of dengue from hospitalized and ambulatory cases in Singapore. We consider inter alia the impacts of dengue on the economy using the human-capital and the friction cost methods. Disease burden was estimated using disability-adjusted life years (DALYs and the cost-effectiveness of a potential vaccine program was evaluated. The average economic impact of dengue illness in Singapore from 2000 to 2009 in constant 2010 US$ ranged between $0.85 billion and $1.15 billion, of which control costs constitute 42%-59%. Using empirically derived disability weights, we estimated an annual average disease burden of 9-14 DALYs per 100 000 habitants, making it comparable to diseases such as hepatitis B or syphilis. The proportion of symptomatic dengue cases detected by the national surveillance system was estimated to be low, and to decrease with age. Under population projections by the United Nations, the price per dose threshold for which vaccines stop being more cost-effective than the current vector control program ranged from $50 for mass vaccination requiring 3 doses and only conferring 10 years of immunity to $300 for vaccination requiring 2 doses and conferring lifetime immunity. The thresholds for these vaccine programs to not be cost-effective for Singapore were $100 and $500 per dose respectively. CONCLUSIONS: Dengue illness presents a serious economic and disease burden in Singapore. Dengue vaccines are expected to be cost-effective if reasonably low prices are adopted and will help to reduce the economic and disease burden of dengue in Singapore substantially.

Helminths/HIV co-infections are very common in developing countries, especially in Africa. The effect of overlapping distribution of HIV and helminths becomes important because concomitant infection may exacerbate disease outcome of HIV infection. The study aimed at determining the effect of deworming on the immune status of helminth/HIV coinfected Pre-ART HIV patients attending three health institutions in Southern Ethiopia. 97 HIV-positive Pre-ART individuals were observed into 2 groups on the basis of helminth co-infection and no infection. Out of these, 66 study participants were helminths/HIV co-infected and the remaining 31 study participants were helminths (-)/HIV (+) control. Helminth/HIV co-infected participants CD4+ T-cell count was done at baseline, after 15 weeks and 6 months after antihelminthics treatment. Data were analyzed using SPSS version 16. Ascaris lumbricoides was the highest prevalent soil transmitted helminths in Pre-ART individuals in this study. CD4+ T-cell count in the Ascaris lumricoides/HIV co-infected was significantly higher (P = 0.05) and (P intestinal helminth parasites detected in the study. In conclusion, this finding on Ascaris lumbricoides-specific nature of immune interaction in helminth/HIV co-infection may partly explain the inconsistent reports on the role of intestinal helminths on progression of HIV infection to AIDS. Therefore, a well-designed longitudinal study on helminth species-specific HIV/helminth co-infection will be needed to fully establish the possible benefits of deworming in intestinal helminth/HIV co-infection.

Repetitive immunization enhances the susceptibility of mice to peripherally administered prions.

Directory of Open Access Journals (Sweden)

Juliane Bremer

Full Text Available The susceptibility of humans and animals to prion infections is determined by the virulence of the infectious agent, by genetic modifiers, and by hitherto unknown host and environmental risk factors. While little is known about the latter two, the activation state of the immune system was surmised to influence prion susceptibility. Here we administered prions to mice that were repeatedly immunized by two initial injections of CpG oligodeoxynucleotides followed by repeated injections of bovine serum albumin/alum. Immunization greatly reduced the required dosage of peripherally administered prion inoculum necessary to induce scrapie in 50% of mice. No difference in susceptibility was observed following intracerebral prion challenge. Due to its profound impact onto scrapie susceptibility, the host immune status may determine disease penetrance after low-dose prion exposure, including those that may give rise to iatrogenic and variant Creutzfeldt-Jakob disease.
