    It is estimated that pneumonia is responsible for 15% of childhood deaths worldwide. Recent research has shown that hypoxia and malnutrition are strong predictors of mortality in children hospitalized for pneumonia. It is estimated that 15% of children under 5 who are hospitalized for pneumonia have hypoxaemia and that around 1.5 million children with severe pneumonia require oxygen treatment each year. We developed a deterministic compartmental model that links the care pathway to disease progression to assess the impact of introducing pulse oximetry as a prognostic tool to distinguish severe from non-severe pneumonia in under-5 year olds across 15 countries with the highest burden worldwide. We estimate that, assuming access to supplemental oxygen, pulse oximetry has the potential to avert up to 148,000 deaths if implemented across the 15 countries. By contrast, integrated management of childhood illness alone has a relatively small impact on mortality owing to its low sensitivity. Pulse oximetry can significantly increase the incidence of correctly treated severe cases as well as reduce the incidence of incorrect treatment with antibiotics. We also found that the combination of pulse oximetry with integrated management of childhood illness is highly cost-effective, with median estimates ranging from US$2.97 to $52.92 per disability-adjusted life year averted in the 15 countries analysed. This combination of substantial burden reduction and favourable cost-effectiveness makes pulse oximetry a promising candidate for improving the prognosis for children with pneumonia in resource-poor settings.

    Pneumonia is an illness, usually caused by infection, in which the lungs become inflamed and congested, reducing oxygen exchange and leading to cough and breathlessness. It affects individuals of all ages but occurs most frequently in children and the elderly. Among children, pneumonia is the most common cause of death worldwide. Historically, in developed countries, deaths from pneumonia have been reduced by improvements in living conditions, air quality, and nutrition. In the developing wor...

    Full Text Available One of the major causes of mortality in children younger than 5 years old is acute lower respiratory tract infections (ALRI. ALRI clinical features are cough, tachypnea, fever, coryza, chest retraction, crackles and wheeze. Increased white blood cell count with left shift might happen in pneumonia. C-reactive protein (CRP and erythrocyte sedimentation rate (ESR might rise in children with respiratory tract infections. Vitamin A deficiency is associated with severe childhood infections. The effect of vitamin A supplementation in childhood pneumonia depends on the prevalence and the level of vitamin A deficiency in the population. Some studies confirmed that retinol levels were significantly higher after recovery from acute pneumonia compared to acute phase. But there were no significant association between serum retinol level and the clinical manifestation.

  4. Childhood Pneumonia Screener: a concept

    Full Text Available Childhood pneumonia continues to be the number one cause of death in children under five years of age in developing countries. In addition to mortality, pneumonia constitutes an enormous economic and social burden because late diagnosis is associated with high cost of treatment and often leads to chronic health problems. There are several bottlenecks in developing countries in the case flow of a child with lung infection: 1 recognising the symptoms as a reason to seek care, 2 getting the patient to a first-tier health facility, 3 scarcity of trained healthcare personnel who can diagnose the condition and its severity, 4 access to a second-tier facility in severe cases. These factors are commonly present in rural areas but even in more urban settings, access to a physician is often delayed. The Childhood Pneumonia Screener project aims at bridging the diagnostic gap using emerging technology. Mobile “smart” phone communication with several inexpensive dedicated sensors is proposed as a rapid data-collection and transmission unit that is connected to a central location where trained personnel assisted by sophisticated signal processing algorithms, evaluate the data and determine if the child is likely to have pneumonia and what the level and urgency of care should be.

    Full Text Available The recent series of reviews conducted within the Global Action Plan for Pneumonia and Diarrhoea (GAPPD addressed epidemiology of the two deadly diseases at the global and regional level; it also estimated the effectiveness of interventions, barriers to achieving high coverage and the main implications for health policy. The aim of this paper is to provide the estimates of childhood pneumonia at the country level. This should allow national policy–makers and stakeholders to implement proposed policies in the World Health Organization (WHO and UNICEF member countries.

  6. mPneumonia: Development of an Innovative mHealth Application for Diagnosing and Treating Childhood Pneumonia and Other Childhood Illnesses in Low-Resource Settings.

    Amy Sarah Ginsburg

    Full Text Available Pneumonia is the leading infectious cause of death in children worldwide. Each year, pneumonia kills an estimated 935,000 children under five years of age, with most of these deaths occurring in developing countries. The current approach for pneumonia diagnosis in low-resource settings--using the World Health Organization Integrated Management of Childhood Illness (IMCI paper-based protocols and relying on a health care provider's ability to manually count respiratory rate--has proven inadequate. Furthermore, hypoxemia--a diagnostic indicator of the presence and severity of pneumonia often associated with an increased risk of death--is not assessed because pulse oximetry is frequently not available in low-resource settings. In an effort to address childhood pneumonia mortality and improve frontline health care providers' ability to diagnose, classify, and manage pneumonia and other childhood illnesses, PATH collaborated with the University of Washington to develop "mPneumonia," an innovative mobile health application using an Android tablet. mPneumonia integrates a digital version of the IMCI algorithm with a software-based breath counter and a pediatric pulse oximeter. We conducted a design-stage usability field test of mPneumonia in Ghana, with the goal of creating a user-friendly diagnostic and management tool for childhood pneumonia and other childhood illnesses that would improve diagnostic accuracy and facilitate adherence by health care providers to established guidelines in low-resource settings. The results of the field test provided valuable information for understanding the usability and acceptability of mPneumonia among health care providers, and identifying approaches to iterate and improve. This critical feedback helped ascertain the common failure modes related to the user interface design, navigation, and accessibility of mPneumonia and the modifications required to improve user experience and create a tool aimed at decreasing

    Full Text Available Abstract Background Oxygen therapy is recommended for all of the 1.5 – 2.7 million young children who consult health services with hypoxemic pneumonia each year, and the many more with other serious conditions. However, oxygen supplies are intermittent throughout the developing world. Although oxygen is well established as a treatment for hypoxemic pneumonia, quantitative evidence for its effect is lacking. This review aims to assess the utility of oxygen systems as a method for reducing childhood mortality from pneumonia. Methods Aiming to improve priority setting methods, The Child Health and Nutrition Research Initiative (CHNRI has developed a common framework to score competing interventions into child health. That framework involves the assessment of 12 different criteria upon which interventions can be compared. This report follows the proposed framework, using a semi-systematic literature review and the results of a structured exercise gathering opinion from experts (leading basic scientists, international public health researchers, international policy makers and representatives of pharmaceutical companies, to assess and score each criterion as their “collective optimism” towards each, on a scale from 0 to 100%. Results A rough estimate from an analysis of the literature suggests that global strengthening of oxygen systems could save lives of up to 122,000 children from pneumonia annually. Following 12 CHNRI criteria, the experts expressed very high levels of optimism (over 80% for answerability, low development cost and low product cost; high levels of optimism (60-80% for low implementation cost, likelihood of efficacy, deliverability, acceptance to end users and health workers; and moderate levels of optimism (40-60% for impact on equity, affordability and sustainability. The median estimate of potential effectiveness of oxygen systems to reduce the overall childhood pneumonia mortality was ~20% (interquartile range: 10-35%, min

    Advocacy, policy, research and intervention efforts against childhood pneumonia have lagged behind other health issues, including malaria, measles and tuberculosis. Accelerating progress on the issue began in 2008, following decades of efforts by individuals and organizations to address the leading cause of childhood mortality and establish a global health network. This article traces the history of this network's formation and evolution to identify lessons for other global health issues. Through document review and interviews with current, former and potential network members, this case study identifies five distinct eras of activity against childhood pneumonia: a period of isolation (post WWII to 1984), the duration of WHO's Acute Respiratory Infections (ARI) Programme (1984-1995), Integrated Management of Childhood illness's (IMCI) early years (1995-2003), a brief period of network re-emergence (2003-2008) and recent accelerating progress (2008 on). Analysis of these eras reveals the critical importance of building a shared identity in order to form an effective network and take advantage of emerging opportunities. During the ARI era, an initial network formed around a relatively narrow shared identity focused on community-level care. The shift to IMCI led to the partial dissolution of this network, stalled progress on addressing pneumonia in communities and missed opportunities. Frustrated with lack of progress on the issue, actors began forming a network and shared identity that included a broad spectrum of those whose interests overlap with pneumonia. As the network coalesced and expanded, its members coordinated and collaborated on conducting and sharing research on severity and tractability, crafting comprehensive strategies and conducting advocacy. These network activities exerted indirect influence leading to increased attention, funding, policies and some implementation.

    Mycoplasma pneumoniae is a frequent cause of acute respiratory infections in both children and adults.It can cause pharyngitis, otitis, tracheobronchitis, or community-acquired pneumonia, but may also remain totally asymptomatic.Mycoplasma pneumoniae is an organism that reportedly has a strong relationship to asthma.The role of atypical bacterial infection in the pathogenesis of asthma is a subject of continuing debate. There is an increasing body of literature concerning the association between Mycoplasma pneumoniae ( M. pneumoniae) and asthma pathogenesis.Moreover, many studies investigating such a link have been uncontrolled and have provided conflicting evidence, in part due to the difficulty in accurately diagnosing infection with these atypical pathogens. Large, general population-based prospective studies are necessary to investigate the development of asthma induced by M. pneumoniae infection in humans. This manuscript will review the relationship between M.pneumoniae infection and childhood asthma.

    Full Text Available Pneumonia is an important cause of morbidity and mortality among children throughout the world. Vaccines are available for some organisms, but they are underutilized and/or still in development. To evaluate the potential impact of vaccines, we review studies in which the etiology of childhood community-acquired pneumonia was recorded. In North America and Europe (9 studies, the etiology of pneumonia was established in 62% of studied children (range 43%-88% by use of noninvasive specific methods for microbiologic diagnosis. The most often identified agents were S. pneumoniae (22%, respiratory syncytial virus (RSV (20%, Haemophilus influenzae (7%, and Mycoplasma pneumoniae (15%. In Africa and South America (8 studies, bacteria were recovered from 56% (range 32%-68% of severely ill children studied by lung aspirate. The most often isolated bacteria were Streptococcus pneumoniae (33% and Haemophilus influenzae (21%. A high percentage of H. influenzae strains were not serotype b. Throughout the world, children requiring hospitalization were most likely to have infection caused by pneumococcus H. influenzae or RSV. Out patients also had Mycoplasma pneumoniae. Countries in Africa and Asia recorded 2 to 10 times more children with pneumonia (7 to 40/100 annually than in the USA. Widespread use of pneumococcal and H. influenzae type b conjugate vaccines could reduce the frequency of childhood pneumonia by one-third. Further reduction will require development of non-type b H. influenzae, RSV and M. pneumoniae vaccines. This could result in a > 50% reduction of pneumonia in children. This goal should be sought and achieved as soon as possible.

    Full Text Available Background: Pneumonia is the leading killer in under-five children. Therefore, by identifying the danger signs, we are able to predict children who are at higher risk of mortality. The objective of the study is to identify the relationship between the clinical profile and mortality in children with pneumonia at Dr. Hasan Sadikin General Hospital, Bandung. Methods: This was an analytical study with a retrospective case control approach using medical records with patient’s age limitation of 1–60 month. The study period started on January 1st 2010 and ended on December 31st 2011. All types of pneumonia included whereas congenital anomalies, immunocompromised and Down’s syndrome patients were excluded in this study. Data were presented as frequency distribution. Results: During the study period, there were 653 children under age of 5 with pneumonia. Only 56 subjects met the inclusion and exclusion criteria. Twenty-eight patients with pneumonia were cured and 28 died. Based on the phi’s coefficient, tachycardia (α-value = 0.019 and hepatomegaly (α-value = 0.001 were significant predictors of death and based on the Mantel-Haenszel analysis, hepatomegaly (OR=9.62, CI 95% 2.349–39.35 was significant as a risk for mortality. Inability to drink, cyanosis, tachypnea, grunting, vomiting, convulsion, and unconsciousness were not related to mortality. Conclusion: Tachycardia and hepatomegaly have a significant relationship with mortality in under-five children with pneumonia.

  13. Setting priorities for development of emerging interventions against childhood pneumonia, meningitis and influenza

    Full Text Available WAcute lower respiratory infections, which broadly include pneumonia and bronchiolitis, are still the leading cause of childhood mortality. ALRI contributed to 18% of all deaths in children younger than five years of age in 2008, and the main pathogens responsible for high mortality were Streptococcus pneumoniae, Haemophilus influenzae and respiratory syncytial virus. In addition, meningitis was estimated to contribute up to 200 000 deaths each year, and influenza anywhere between 25 000 and 110 000. It is widely acknowledged that a major portion of this mortality should be avoidable if universal coverage of all known effective interventions could be achieved. However, some evaluations of the implementation of World Health Organization’s (WHO Integrated Management of Childhood Illness (IMCI strategy, which promotes improved access to a trained health provider who can administer “standard case management”, have shown somewhat disappointing results. Only a minority of all children with life-threatening episodes of pneumonia, meningitis and influenza in developing countries have access to trained health providers and receive appropriate treatment. Thus, novel strategies for control of pneumonia that balance investments in scaling up of existing interventions and the development of novel approaches, technologies and ideas are clearly needed.

  14. Predicting pneumonia and influenza mortality from morbidity data.

    Lise Denoeud

    Full Text Available BACKGROUND: Few European countries conduct reactive surveillance of influenza mortality, whereas most monitor morbidity. METHODOLOGY/PRINCIPAL FINDINGS: We developed a simple model based on Poisson seasonal regression to predict excess cases of pneumonia and influenza mortality during influenza epidemics, based on influenza morbidity data and the dominant types/subtypes of circulating viruses. Epidemics were classified in three levels of mortality burden ("high", "moderate" and "low". The model was fitted on 14 influenza seasons and was validated on six subsequent influenza seasons. Five out of the six seasons in the validation set were correctly classified. The average absolute difference between observed and predicted mortality was 2.8 per 100,000 (18% of the average excess mortality and Spearman's rank correlation coefficient was 0.89 (P = 0.05. CONCLUSIONS/SIGNIFICANCE: The method described here can be used to estimate the influenza mortality burden in countries where specific pneumonia and influenza mortality surveillance data are not available.

  15. Infection by Mycoplasma pneumoniae and its importance as an etiological agent in childhood community-acquired pneumonias

    Full Text Available This manuscript reviewed the literature on infection by Mycoplasma pneumoniae with emphasis on etiological aspects of childhood community-acquired pneumonias. Bibliographical research was carried out from Pubmed Medline, MDConsult, HighWire, LILACS, and direct research over the past 10 years with the following keywords: Mycoplasma pneumoniae, pneumonia, and childhood. Fifty-four articles were selected. Mycoplasma pneumoniae has a high incidence in childhood. Clinical presentation includes respiratory and extrarespiratory symptoms. Mycoplasma pneumoniae lung infection can be confused with viral or bacterial pneumonia and is unresponsive to beta-lactams. In addition, co-infections have been reported. Mycoplasma pneumoniae infection occurs in all age groups, being less frequent and more severe in children under the age of five. Its incidence as a causal agent is high. Mycoplasma pneumoniae infections constitute 20%-40% of all community-acquired pneumonias; the severity is highly variable, and this condition may lead to severe sequelae. Mycoplasma pneumoniae frequency is underestimated in clinical practice because of the lack of specific features and a diagnosis that needs serology or PCR. Effective management of M. pneumoniae infections can usually be achieved with macrolides. In Brazil, epidemiological studies are needed in order to assess the incidence of this bacterium.

  16. Zinc as an adjunct for childhood pneumonia - interpreting early results.

    Zinc supplementation has been consistently shown to reduce the incidence of childhood pneumonia, but its effect on the course of pneumonia when administered as an adjunct to antibiotic therapy is still unclear. Three trials published to date have shown mixed results, and a recent trial from India raises the possibility that zinc may be detrimental in some circumstances. Study sites and designs differ, particularly in the timing of zinc treatment and in determining recovery from pneumonia, which can explain the differences in study findings. Serum zinc concentrations are unreliable indicators of zinc status, particularly during acute infectious illnesses. Subgroup analyses, especially using serum zinc levels, must be cautioned against. Future studies are needed that are large enough to be sufficiently powered to accommodate larger treatment failure rates, an issue that ongoing trials will hopefully address.

    Objective. To investigate the value of CT in complicated childhood pneumonia and its role in early intervention when chest radiography (CXR) is non-contributory. Materials and methods. Forty-two immunocompetent children, aged 1-11 years, admitted for community-acquired pneumonia from October 1997 to September 1999, had 42 contrast-enhanced CT scans and frontal chest radiographs on the same day, which were assessed independently. CT was performed when the patient remained unwell and the CXR images showed failure of resolution despite 7-10 days of antibiotics and/or drainage with urokinase therapy. Results. Compared to CT, CXR revealed suboptimal accuracy rates of lobar involvement (84%), chest tube placement (73%), fluid loculation (42%), abscess formation (40%) and bronchopleural fistulae (33%). It could not assess parenchymal or pleural complications such as cavitary necrosis, early abscess formation, empyemas or pericardial effusions. On the basis of the CT findings and poor clinical progress, 16 patients underwent surgical intervention with the aid of video-assisted thorascopic surgery (VATS). The CT features correlated well with surgical findings. Ten cases required pleural decortication while six with destructive or necrotic lung lesions had surgical resection. Debridement was difficult when the pleura had become thick and fibrotic. Streptococcus pneumoniae was the offending organism in 81% of cases. The right side was affected in 67% of cases. Conclusions. In complicated childhood pneumonia, CT is far superior to CXR in revealing pleural and parenchymal complications, which may require early surgical intervention. (orig.)

    The aim of this study was to illustrate the chest radiographs (CR) and CT imaging features and sequential findings of cavitary necrosis in complicated childhood pneumonia. Among 30 children admitted in the Pediatric Intensive Care Unit for persistent or progressive pneumonia, respiratory distress or sepsis despite adequate antibiotic therapy, a study group of 9 children (5 girls and 4 boys; mean age 4 years) who had the radiographic features and CT criteria for cavitary necrosis complicated pneumonia was identified. The pathogens identified were Streptococcus pneumoniae (n=4), Aspergillus (n=2), Legionella (n=1), and Staphylococcus aureus (n=1). Sequential CR and CT scans were retrospectively reviewed. Follow-up CR and CT were evaluated for persistent abnormalities. Chest radiographs showed consolidations in 8 of the 9 patients. On CT examination, cavitary necrosis was localized to 1 lobe in 2 patients and 7 patients showed multilobar or bilateral areas of cavitary necrosis. In 3 patients of 9, the cavitary necrosis was initially shown on CT and visualization by CR was delayed by a time span varying from 5 to 9 days. In all patients with cavities, a mean number of five cavities were seen on antero-posterior CR, contrasting with the multiple cavities seen on CT. Parapneumonic effusions were shown by CR in 3 patients and in 5 patients by CT. Bronchopleural fistulae were demonstrated by CT alone (n=3). No purulent pericarditis was demonstrated. The CT scan displayed persistent residual pneumatoceles of the left lower lobe in 2 patients. Computed tomography is able to define a more specific pattern of abnormalities than conventional CR in children with necrotizing pneumonia and allows an earlier diagnosis of this rapidly progressing condition. Lung necrosis and cavitation may also be associated with Aspergillus or Legionella pneumonia in the pediatric population. (orig.)

    Pneumonias are a major cause of morbidity and mortality and their prognosis depends on many factors including nutritional status. This study analyzed the relationship between malnutrition and the risk of death in Community Acquired Pneumonia (CAP) patients. This is a prospective observational study. The Subjective Global Assessment (SGA) was used as a screening tool to appraise the nutritional status. Ninety-eight patients with CAP requiring hospitalization were included consecutively from October 2004 to September 2006. The clinical, bacteriological and laboratory features were recorded. Patient's nutritional condition was assessed using the SGA. The monitoring was performed until discharge, death or shunt. Persistent cough or fever, the presence of pleural effusion, malignancies or long hospitalization were associated with worse prognosis. Mortality increased in proportion to the degree of malnutrition. Thirty two CAP patients (32.65%) were classified as SGA-category A; 44 (44.90%) as SGA-B, and 22 (22.45%) as SGA-C. Pneumonia resulted in death in 3/32 SGA-A (9.37%), 8/44 SGA-B (18.18%) and 10/22 SGA-C patients. SGA-C patients showed significantly higher odds ratios for death in comparison to SGA-A patients (OR = 6.085, CI95%: 1.071-34.591; p = 0.042). Considering death as the outcome variable, SGA-A class had the highest negative predictive value (0.906), while SGA-C class showed the highest positive predictive value (0.455). These results link the nutritional status to the NAC evolution prognostic. SGA provides a simple estimation of the nutritional status and it is a good predictor of the risk of death in CAP patients.

    The Grameen Bank (GB) is a highly innovative and well-supervised credit program for the rural poor in Bangladesh. About 95% of over 2 million participants are women. GB can positively affect child survival among its participants through its income-generation and consciousness-raising activities. The study examines if GB influences childhood mortality among its participants. An integrated family life survey was carried out during 1993-94 among about 2500 married women in landless households who are eligible for membership in GB. The survey was carried out among randomly selected married women regardless of GB membership in 3 thanas of Tangail district and 1 thana of Mymensingh district. The study permits an analysis in a "before-after" and "treatment-comparison" framework for measuring the impact of GB on childhood mortality. Estimation was done through proportional hazards models, where the effects of confounding factors like calendar year, maternal age, parity, maternal education, economic conditions, and areal variation were controlled for. There was a 34% and significant reduction in childhood (under-5) mortality after the mothers joined the GB. Similar effects of other NGOs on childhood mortality were also observed. Childhood mortality was similar between the GB members before joining the Bank and never-members, indicating that the GB members were not from a selective group. Childhood mortality was 21% and significantly lower among women who worked for income generation than those women who did not work. Income generation and social development programs modeled after the GB and other NGOs can reduce childhood mortality in Bangladesh and similar settings.

    Background The pneumococcal conjugate vaccine’s (PCV) impact on childhood pneumonia during programmatic conditions in Africa is poorly understood. Following PCV13 introduction in Malawi in November 2011, we evaluated the case burden and rates of childhood pneumonia. Methods and Findings Between January 1, 2012-June 30, 2014 we conducted active pneumonia surveillance in children 75% three-dose PCV13 coverage (post). We also used multivariable time-series regression, adjusting for autocorrelation and exploring seasonal variation and alternative model specifications in sensitivity analyses. The early versus post analysis showed an increase in cases and rates of total, fast breathing, and indrawing pneumonia and a decrease in danger sign and hypoxemic pneumonia, and pneumonia mortality. At 76% three-dose PCV13 coverage, versus 0%, the time-series model showed a non-significant increase in total cases (+47%, 95% CI: -13%, +149%, p = 0.154); fast breathing cases increased 135% (+39%, +297%, p = 0.001), however, hypoxemia fell 47% (-5%, -70%, p = 0.031) and hospital deaths decreased 36% (-1%, -58%, p = 0.047) in children <5 years. We observed a shift towards disease without danger signs, as the proportion of cases with danger signs decreased by 65% (-46%, -77%, p<0.0001). These results were generally robust to plausible alternative model specifications. Conclusions Thirty months after PCV13 introduction in Malawi, the health system burden and rates of the severest forms of childhood pneumonia, including hypoxemia and death, have markedly decreased.

    The effect of temperature on childhood pneumonia in subtropical regions is largely unknown so far. This study examined the impact of temperature on childhood pneumonia in Brisbane, Australia. A quasi-Poisson generalized linear model combined with a distributed lag non-linear model was used to quantify the main effect of temperature on emergency department visits (EDVs) for childhood pneumonia in Brisbane from 2001 to 2010. The model residuals were checked to identify added effects due to heat waves or cold spells. Both high and low temperatures were associated with an increase in EDVs for childhood pneumonia. Children aged 2-5 years, and female children were particularly vulnerable to the impacts of heat and cold, and Indigenous children were sensitive to heat. Heat waves and cold spells had significant added effects on childhood pneumonia, and the magnitude of these effects increased with intensity and duration. There were changes over time in both the main and added effects of temperature on childhood pneumonia. Children, especially those female and Indigenous, should be particularly protected from extreme temperatures. Future development of early warning systems should take the change over time in the impact of temperature on children's health into account.

    Full Text Available Pneumonia is a leading cause of deaths in infants and young children in developing countries, including the Philippines. However, data at the community level remains limited. Our study aimed to estimate incidence and mortality rates and to evaluate risk factors and health-seeking behavior for childhood pneumonia. A household level interview survey was conducted in Biliran Island, the Philippines. Caregivers were interviewed using a semi-structured questionnaire to check if children had symptoms suggesting pneumonia-like episodes from June 2011 to May 2012. Of 3,327 households visited in total, 3,302 (99.2% agreed to participate, and 5,249 children less than 5 years of age were included in the study. Incidence rates of pneumonia-like episodes, severe pneumonia-like episodes, and pneumonia-associated mortality were 105, 61, and 0.9 per 1,000 person-years, respectively. History of asthma [hazard ratio (HR: 5.85, 95% confidence interval (CI: 4.83-7.08], low socioeconomic status (SES (HR: 1.11, 95% CI: 1.02-1.20, and long travel time to the healthcare facility estimated by cost distance analysis (HR: 1.32, 95% CI: 1.09-1.61 were significantly associated with the occurrence of pneumonia-like episodes by the Cox proportional hazards model. For severe pneumonia-like episodes, a history of asthma (HR: 8.39, 95% CI: 6.54-10.77 and low SES (HR: 1.30, 95% CI: 1.17-1.45 were significant risk factors. Children who had a long travel time to the hospital were less likely to seek hospital care (Odds ratio: 0.32, 95% CI: 0.19-0.54 when they experienced severe pneumonia-like episodes. Incidence of pediatric pneumonia-like episodes was associated with a history of asthma, SES, and the travel time to healthcare facilities. Travel time was also identified as a strong indicator for health-seeking behavior. Improved access to healthcare facilities is important for early and effective management. Further studies are warranted to understand the causal relationship

    Patients infected or colonized with carbapenem-resistant Klebsiella pneumoniae (CRKp) are often chronically and acutely ill, which results in substantial mortality unrelated to infection. Therefore, estimating excess mortality due to CRKp infections is challenging. The Consortium on Resistance against Carbapenems in K. pneumoniae (CRACKLE) is a prospective multicenter study. Here, patients in CRACKLE were evaluated at the time of their first CRKp bloodstream infection (BSI), pneumonia or urinary tract infection (UTI). A control cohort of patients with CRKp urinary colonization without CRKp infection was constructed. Excess hospital mortality was defined as mortality in cases after subtracting mortality in controls. In addition, the adjusted hazard ratios (aHR) for time-to-hospital-mortality at 30 days associated with infection compared with colonization were calculated in Cox proportional hazard models. In the study period, 260 patients with CRKp infections were included in the BSI (90 patients), pneumonia (49 patients) and UTI (121 patients) groups, who were compared with 223 controls. All-cause hospital mortality in controls was 12%. Excess hospital mortality was 27% in both patients with BSI and those with pneumonia. Excess hospital mortality was not observed in patients with UTI. In multivariable analyses, BSI and pneumonia compared with controls were associated with aHR of 2.59 (95% CI 1.52-4.50, p pneumonia is associated with the highest excess hospital mortality. Patients with BSI have slightly lower excess hospital mortality rates, whereas excess hospital mortality was not observed in hospitalized patients with UTI.

    The study aims were to identify CT features that predict outcome of fibrotic idiopathic interstitial pneumonia (IIP) when information from lung biopsy data is unavailable. HRCTs of 146 consecutive patients presenting with fibrotic IIP were studied. Visual estimates were made of the extent of abnormal lung and proportional contribution of fine and coarse reticulation, microcystic (cysts {<=}4 mm) and macrocystic honeycombing. A score for severity of traction bronchiectasis was also assigned. Using death as our primary outcome measure, variables were analysed using the Cox proportional hazards model. CT features predictive of a worse outcome were coarse reticulation, microcystic and macrocystic honeycombing, as well as overall extent of lung abnormality (p < 0.001). Importantly, increased severity of traction bronchiectasis, corrected for extent of parenchymal abnormality, was predictive of poor prognosis regardless of the background pattern of abnormal lung (HR = 1.04, CI = 1.03-1.06, p < 0.001). On bivariate Cox analysis microcystic honeycombing was a more powerful determinant of a poor prognosis than macrocystic honeycombing. In fibrotic IIPs we have shown that increasingly severe traction bronchiectasis is indicative of higher mortality irrespective of the HRCT pattern and extent of disease. Extent of microcystic honeycombing is a more powerful determinant of outcome than macrocystic honeycombing. (orig.)

    Full Text Available The highest incidence of childhood acute lower respiratory tract infection (ALRI is in low- and middle-income countries. Few studies examined whether detection of respiratory viruses predicts ALRI outcomes in these settings.We conducted prospective cohort and case-control studies of children 1-23 months of age in Botswana. Cases met clinical criteria for pneumonia and were recruited within six hours of presentation to a referral hospital. Controls were children without pneumonia matched to cases by primary care clinic and date of enrollment. Nasopharyngeal specimens were tested for respiratory viruses using polymerase chain reaction. We compared detection rates of specific viruses in matched case-control pairs. We examined the effect of respiratory syncytial virus (RSV and other respiratory viruses on pneumonia outcomes.Between April 2012 and August 2014, we enrolled 310 cases, of which 133 had matched controls. Median ages of cases and controls were 6.1 and 6.4 months, respectively. One or more viruses were detected from 75% of cases and 34% of controls. RSV and human metapneumovirus were more frequent among cases than controls, but only enterovirus/rhinovirus was detected from asymptomatic controls. Compared with non-RSV viruses, RSV was associated with an increased risk of treatment failure at 48 hours [risk ratio (RR: 1.85; 95% confidence interval (CI: 1.20, 2.84], more days of respiratory support [mean difference (MD: 1.26 days; 95% CI: 0.30, 2.22 days], and longer duration of hospitalization [MD: 1.35 days; 95% CI: 0.20, 2.50 days], but lower in-hospital mortality [RR: 0.09; 95% CI: 0.01, 0.80] in children with pneumonia.Respiratory viruses were detected from most children hospitalized with ALRI in Botswana, but only RSV and human metapneumovirus were more frequent than among children without ALRI. Detection of RSV from children with ALRI predicted a protracted illness course but lower mortality compared with non-RSV viruses.

    Full Text Available Abstract Introduction Vitamin A is important for the integrity and regeneration of respiratory and gastrointestinal epithelia and is involved in regulating human immune function. It has been shown previously that vitamin A has a preventive effect on all-cause and disease specific mortality in children under five. The purpose of this paper was to get a point estimate of efficacy of vitamin A supplementation in reducing cause specific mortality by using Child Health Epidemiology Reference Group (CHERG guidelines. Methods A literature search was done on PubMed, Cochrane Library and WHO regional data bases using various free and Mesh terms for vitamin A and mortality. Data were abstracted into standardized forms and quality of studies was assessed according to standardized guidelines. Pooled estimates were generated for preventive effect of vitamin A supplementation on all-cause and disease specific mortality of diarrhea, measles, pneumonia, meningitis and sepsis. We did a subgroup analysis for vitamin A supplementation in neonates, infants 1-6 months and children aged 6-59 months. In this paper we have focused on estimation of efficacy of vitamin A supplementation in children 6-59 months of age. Results for neonatal vitamin A supplementation have been presented, however no recommendations are made as more evidence on it would be available soon. Results There were 21 studies evaluating preventive effect of vitamin A supplementation in community settings which reported all-cause mortality. Twelve of these also reported cause specific mortality for diarrhea and pneumonia and six reported measles specific mortality. Combined results from six studies showed that neonatal vitamin A supplementation reduced all-cause mortality by 12 % [Relative risk (RR 0.88; 95 % confidence interval (CI 0.79-0.98]. There was no effect of vitamin A supplementation in reducing all-cause mortality in infants 1-6 months of age [RR 1.05; 95 % CI 0.88-1.26]. Pooled results for

    Little is known about cause-specific long-term mortality beyond 30 days in pneumonia. We aimed to compare the mortality of patients with hospitalized pneumonia compared to age- and sex-matched controls beyond 30 days. Participants were drawn from the European Prospective Investigation into Cancer (EPIC)-Norfolk prospective population study. Hospitalized pneumonia cases were identified from record linkage (ICD-10: J12-J18). For this study we excluded people with hospitalized pneumonia who died within 30 days. Each case identified was matched to four controls and followed up until the end June 2012 (total 15 074 person-years, mean 6·1 years, range 0·08-15·2 years). Cox regression models were constructed to examine the all-cause, respiratory and cardiovascular mortality using date of pneumonia onset as baseline with binary pneumonia status as exposure. A total of 2465 men and women (503 cases, 1962 controls) [mean age (s.d.) 64·5 (8·3) years] were included in the study. Between a 30-day to 1-year period, hazard ratios (HRs) of all-cause and cardiovascular mortality were 7·3 [95% confidence interval (CI) 5·4-9·9] and 5·9 (95% CI 3·5-9·7), respectively (with very few respiratory deaths within the same period) in cases compared to controls after adjusting for age, sex, asthma, smoking status, pack years, systolic and diastolic blood pressure, diabetes, physical activity, waist-to-hip ratio, prevalent cardiovascular and respiratory diseases. All outcomes assessed also showed increased risk of death in cases compared to controls after 1 year; respiratory cause of death being the most significant during that period (HR 16·4, 95% CI 8·9-30·1). Hospitalized pneumonia was associated with increased all-cause and specific-cause mortality beyond 30 days.

    Full Text Available Abstract Background Each year almost one million newborns die from infections, mostly in low-income countries. Timely case management would save many lives but the relative mortality effect of varying strategies is unknown. We have estimated the effect of providing oral, or injectable antibiotics at home or in first-level facilities, and of in-patient hospital care on neonatal mortality from pneumonia and sepsis for use in the Lives Saved Tool (LiST. Methods We conducted systematic searches of multiple databases to identify relevant studies with mortality data. Standardized abstraction tables were used and study quality assessed by adapted GRADE criteria. Meta-analyses were undertaken where appropriate. For interventions with biological plausibility but low quality evidence, a Delphi process was undertaken to estimate effectiveness. Results Searches of 2876 titles identified 7 studies. Among these, 4 evaluated oral antibiotics for neonatal pneumonia in non-randomised, concurrently controlled designs. Meta-analysis suggested reductions in all-cause neonatal mortality (RR 0.75 95% CI 0.64- 0.89; 4 studies and neonatal pneumonia-specific mortality (RR 0.58 95% CI 0.41- 0.82; 3 studies. Two studies (1 RCT, 1 observational study, evaluated community-based neonatal care packages including injectable antibiotics and reported mortality reductions of 44% (RR= 0.56, 95% CI 0.41-0.77 and 34% (RR =0.66, 95% CI 0.47-0.93, but the interpretation of these results is complicated by co-interventions. A third, clinic-based, study reported a case-fatality ratio of 3.3% among neonates treated with injectable antibiotics as outpatients. No studies were identified evaluating injectable antibiotics alone for neonatal pneumonia. Delphi consensus (median from 20 respondents effects on sepsis-specific mortality were 30% reduction for oral antibiotics, 65% for injectable antibiotics and 75% for injectable antibiotics on pneumonia-specific mortality. No trials were

    Events causing stress responses during sensitive periods of rapid neurological development in childhood may be early determinants of all-cause premature mortality. Using a British birth cohort study of individuals born in 1958, the relationship between adverse childhood experiences (ACE) and mortality≤50 year was examined for men (n=7,816) and women (n=7,405) separately. ACE were measured using prospectively collected reports from parents and the school: no adversities (70%); one adversity (22%), two or more adversities (8%). A Cox regression model was carried out controlling for early life variables and for characteristics at 23 years. In men the risk of death was 57% higher among those who had experienced 2+ ACE compared to those with none (HR 1.57, 95% CI 1.13, 2.18, p=0.007). In women, a graded relationship was observed between ACE and mortality, the risk increasing as ACE accumulated. Women with one ACE had a 66% increased risk of death (HR 1.66, 95% CI 1.19, 2.33, p=0.003) and those with ≥2 ACE had an 80% increased risk (HR 1.80, 95% CI 1.10, 2.95, p=0.020) versus those with no ACE. Given the small impact of adult life style factors on the association between ACE and premature mortality, biological embedding during sensitive periods in early development is a plausible explanatory mechanism.

    Full Text Available Background: Community acquired pneumonia is a common disease that is associated with significant morbidity and mortality rates. In the General University Hospital ´´Dr. Gustavo Aldereguía Lima¨ in Cienfuegos, there are guidelines for the management of patients with community-acquired pneumonia, but no studies have been conducted as to the relation between their compliance and the mortality rate. Objective: To assess the adherence to guidelines for diagnosis and treatment of community-acquired pneumonia and its relation to mortality in hospitalized patients. Methods: A descriptive, observational and prospective case series study was conducted in all patients with a diagnosis of pneumonia or bronchopneumonia at the moment of admission and discharge from June 2006 to May 31, 2007. The relation between the different variables and the mortality rate was analyzed as to the different types of risks and the overall compliance with the guidelines for each risk with mortality. A multivariate analysis (logistic regression was performed, with a 95% confidence interval. Results: The results are presented in tables of numbers and percent. Variables independently associated with mortality were: age (over 65 years old people, radiological lesions in more than one lobe or bilateral, atypical pneumonia debut, negative assessments as to the adherence to guidelines and inadequate treatments. Conclusion: The variables included in the study were enough to explain the final outcome of the patients, so it could be determined, for the first time in Cienfuegos, that the non-compliance with the guidelines of good clinical practice is related to mortality rates.

    The impact of vaccination on non-bacteremic Haemophilus influenza pneumonia is difficult to appreciate, in the absence of proper microbiological documentation. It has certainly been largely underestimated. Vaccination has reduced the incidence of pneumococcal pneumonia. However, the increase of incidence of empyema due to nonvaccine serotypes was observed in several countries. The replacement of Prevenar 7 by Prevenar 13 portends a decrease in the occurrence of these infections, but, unfortunately, without eliminating them completely.

    A total of 19 strains of Klebsiella pneumoniae isolated as sole pathogen from children with diarrhoea were used to study their virulence mechanism using different assays. Eith strains of K. pneumoniae exhibited aggregative adherence that was distinct from the stacked brick enteroaggregative pattern shown by Escherichia coli. The study suggests the presence of a new virulence mechanism in the pathogenesis of Klebsiella-associated diarrhoea.

    Full Text Available Background/Aims: The prognostic role of serum procalcitonin level in critically ill patients with ventilator-associated pneumonia was unclear. The aim of our study was to investigate the relationship between serum procalcitonin level and mortality risk in critically ill patients with ventilator-associated pneumonia. Methods: Data of critically ill patients with ventilator-associated pneumonia were retrospectively collected. Demographics, comorbidities, and serum procalcitonin level were extracted from electronic medical records. The primary outcome was mortality within two months after diagnosis. Multivariable Cox regression analyses were performed to assess the prognostic role of serum procalcitonin level in those patients. Results: A total of 115 critically ill patients with ventilator-associated pneumonia were enrolled in our study. Serum procalcitonin level was not associated with age, gender, or other comorbidities. Univariate Cox regression model showed that high serum procalcitonin level was associated increased risk of morality within 2 months after diagnosis (OR = 2.32, 95% CI 1.25-4.31, P = 0.008. Multivariable Cox regression model showed that high serum procalcitonin level was independently associated increased risk of morality within 2 months after diagnosis (OR = 2.38, 95% CI 1.26-4.50, P = 0.008. Conclusion: High serum procalcitonin level is an independent prognostic biomarker of mortality risk in critically ill patients with ventilator-associated pneumonia, and it's a promising biomarker of prognosis in critically ill patients.

To achieve this, preventive strategies such as expanding vaccination coverage are key. However once a child develops pneumonia prompt treatment which is essential to survival is dependent on mothers and caregiver recognition of the symptoms and danger signs of pneumonia. Methods. This community based cross-sectional study enrolled four hundred and sixty-six caregivers in Enugu state. It aimed to determine knowledge of caregivers about danger signs of pneumonia and the sociodemographic factors that influence knowledge and care seeking behaviour of caregivers. Results. There is poor knowledge of the aetiology and danger signs of pneumonia among caregivers. Higher maternal educational attainment and residence in semiurban area were significantly associated with knowledge of aetiology, danger signs, and vaccination of their children against pneumonia. Fast breathing and difficulty in breathing were the commonest known and experienced WHO recognized danger signs while fever was the commonest perceived danger sign among caregivers. Conclusion. Knowledge of danger signs and health seeking behaviour among caregivers is inadequate. There is need for intensified public and hospital based interventions targeted at mothers to improve their knowledge about pneumonia.

    Shaun K Morris

    Full Text Available BACKGROUND: Little is known about the causes of death in children in India after age five years. The objective of this study is to provide the first ever direct national and sub-national estimates of infectious disease mortality in Indian children aged 5 to 14 years. METHODS: A verbal autopsy based assessment of 3 855 deaths is children aged 5 to 14 years from a nationally representative survey of deaths occurring in 2001-03 in 1.1 million homes in India. RESULTS: Infectious diseases accounted for 58% of all deaths among children aged 5 to 14 years. About 18% of deaths were due to diarrheal diseases, 10% due to pneumonia, 8% due to central nervous system infections, 4% due to measles, and 12% due to other infectious diseases. Nationally, in 2005 about 59 000 and 34 000 children aged 5 to 14 years died from diarrheal diseases and pneumonia, corresponding to mortality of 24.1 and 13.9 per 100 000 respectively. Mortality was nearly 50% higher in girls than in boys for both diarrheal diseases and pneumonia. CONCLUSIONS: Approximately 60% of all deaths in this age group are due to infectious diseases and nearly half of these deaths are due to diarrheal diseases and pneumonia. Mortality in this age group from infectious diseases, and diarrhea in particular, is much higher than previously estimated.

    Full Text Available We investigated the mortality rate of pneumonia (PMR among children under 5 and its time trend from 1996 to 2013 to determine the priorities for ending preventable deaths from pneumonia in children under 5, and share China's successful experience in reducing PMR with other developing countries.We used data from China's Under 5 Child Mortality Surveillance System (U5CMSS to calculate the PMR and the proportion of pneumonia deaths to total deaths of children under 5. The data were grouped by urban and rural areas with Cochran-Mantel-Haensel (CMH test and Chi-square test to examine the differences of PMR and proportion. The time trend was tested by Cochran-Armitage trend test.The overall PMR of children under 5 was reduced by 85.5% (from 1053.2 to 153.2 per 100,000 live births from 1996 to 2013, with the urban and rural areas reduced by 69.1% (from 188.4 to 58.2 per 100,000 live births and 84.7% (from 1252.8 to 191.9 per 100,000 live births, respectively. The overall proportion of pneumonia deaths to total deaths was also declined from 23.4% in 1996 to 12.8% in 2013, with the rural areas decreased from 24.4% to 13.2% and the urban areas decreased from 11.1% to 9.7%. The PMRs in neonates (0-27 days, post-neonates (1-11 months, and childhood (12-59 months were reduced by 80.7%, 77.4%, and 80.1%, respectively in rural areas, and 71.7%, 69.6%, and 39.0%, respectively in urban areas. During 1996-2013, the PMR in children under 5 years was 4.9 fold higher in rural areas relative to that in urban areas, with relative risk (RR of 3.6 and 6.4 in neonates and 1- to 59-month-old children, respectively.PMR in children under 5 significantly declined in China from 1996 to 2013, especially in rural areas. However, huge disparities still existed between rural and urban areas. Infants had the highest PMR, which indicated that interventions aiming at prevention and control of infant pneumonia should be the priority for further reducing PMR in China.

    The ratio of the area under the free (unbound) concentration-time curve to minimum inhibitory concentration (fAUC/MIC) was proposed to be the pharmacokinetic/pharmacodynamic index most strongly linked to the antibacterial effect of colistin against Acinetobacter baumannii. A retrospective study of patients who received colistin to treat pneumonia caused by extensively drug-resistant (XDR) A. baumannii over a 4-year period was performed to assess the impact of the colistin MIC on mortality. A total of 227 patients were included in the analysis. The 7-day and 14-day mortality rates of patients with XDR A. baumannii pneumonia receiving colistin therapy were 15.0% and 23.8%, respectively. In the multivariate analysis, Acute Physiology and Chronic Health Evaluation (APACHE) II score, days from index culture to first dose of colistin, underlying tumour and septic shock at presentation were independent predictors of mortality in patients with XDR A. baumannii pneumonia receiving colistin therapy. In the univariate analysis, the colistin dose based on ideal body weight (IBW) correlated with patient outcome. Therefore, the use of IBW appeared to be more appropriate to calculate the colistin dosage. In addition, these results highlight the clinical significance of colistin MIC in patients with XDR A. baumannii pneumonia receiving colistin therapy. Although MICs were in the 'susceptible' range, patients infected with isolates with high colistin MICs showed a poorer clinical response rate than patients infected with isolates with low colistin MICs. Further clinical studies are needed to evaluate the roles of colistin MIC for predicting mortality in XDR A. baumannii pneumonia with a high colistin MIC.

  8. Incident pneumonia and mortality in patients with chronic obstructive pulmonary disease. A double effect of inhaled corticosteroids?

    2015-01-15

    Inhaled corticosteroids are commonly prescribed for patients with severe chronic obstructive pulmonary disease. Although their use improves quality of life and reduces exacerbations, it is associated with increased risk of pneumonia. Curiously, their use has not been associated with increased risk of pneumonia-related or overall mortality. We review pertinent literature to further explore the effects of inhaled corticosteroids on incident pneumonia and mortality in patients with chronic obstructive pulmonary disease. The association of use of inhaled corticosteroids and incident pneumonia is substantial and has been present in the majority of the studies on the topic. This includes both randomized controlled trials and observational studies. However, all of the studies have substantial risk of bias. Most randomized trials are limited by lack of systematic ascertainment of pneumonia; they depended on adverse event reporting. Many observational studies included proper radiographic assessment of pneumonia, but they are limited by their retrospective, observational design. The unadjusted higher risk of pneumonia is associated with longer duration of use, more potent ICS compounds, and higher doses. That implies a dose-effect relationship. Unlike pneumonia, mortality is a precise outcome. Despite the robust association of inhaled corticosteroid use with increased risk of pneumonia, all studies find either no difference or a reduction in pulmonary-related and overall mortality associated with the use of inhaled corticosteroids. These observations suggest a double effect of inhaled corticosteroids (i.e., an adverse effect plus an unexplained mitigating effect).

    We conducted a cluster randomized trial of the effects of the integrated community case management of childhood illness (iCCM) strategy on careseeking for and coverage of correct treatment of suspected pneumonia, diarrhea, and malaria, and mortality among children aged 2-59 months in 31 districts of the Oromia region of Ethiopia. We conducted baseline and endline coverage and mortality surveys approximately 2 years apart, and assessed program strength after about 1 year of implementation. Results showed strong iCCM implementation, with iCCM-trained workers providing generally good quality of care. However, few sick children were taken to iCCM providers (average 16 per month). Difference in differences analyses revealed that careseeking for childhood illness was low and similar in both study arms at baseline and endline, and increased only marginally in intervention (22.9-25.7%) and comparison (23.3-29.3%) areas over the study period (P = 0.77). Mortality declined at similar rates in both study arms. Ethiopia's iCCM program did not generate levels of demand and utilization sufficient to achieve significant increases in intervention coverage and a resulting acceleration in reductions in child mortality. This evaluation has allowed Ethiopia to strengthen its strategic approaches to increasing population demand and use of iCCM services.

    Full Text Available BACKGROUND: The novel H7N9 virus causes severe illness, including pneumonia and acute respiratory distress syndrome, with high rates of mortality. We investigated the association of initial radiologic characteristics obtained at admission with clinical outcomes in patients with avian influenza H7N9 pneumonia. METHODS: Demographics, comorbidities, clinical findings, radiologic appearance and scores of the affected lung parenchyma were compared between survivor group (n = 15 and mortality group (n = 7. Two radiologic scores were calculated, one using chest radiography and one using CT. Follow-up CT scans at discharge were analyzed in 12 patients of the survival group. RESULTS: All the patients in mortality group developed acute respiratory distress syndrome and required mechanical ventilation, while in the survival group 33% (5/15 developed acute respiratory distress syndrome (P<0.05 and 27% (4/15 required mechanical ventilation (P<0.05. The mean radiographic and CT scores of the mortality group were 50% higher compared to the survival group (P<0.05. ROC analysis revealed an area under curve of 0.738 for the radiographic score with an optimal cutoff value of a score of 19 for prediction of mortality, with a sensitivity of 71% and a specificity of 67%, and an area under curve of 0.833 for the CT score with an optimal cutoff value of a CT score of 21 for prediction of mortality, with a sensitivity of 86% and a specificity of 73%. The mean CT score of the affected lung parenchyma at discharge was 30% lower than the initial CT examination (P<0.05. CONCLUSION: High initial radiologic score is associated with mortality in patients with avian influenza H7N9 pneumonia.

    Full Text Available Background. Current risk stratification tools, primarily used for CAP, are suboptimal in predicting nursing home acquired pneumonia (NHAP outcome and mortality. We conducted a systematic review to evaluate current evidence on the usefulness of proposed predictors of NHAP mortality. Methods. PubMed (MEDLINE, EMBASE, and CINAHL databases were searched for articles published in English between January 1978 and January 2014. The literature search elicited a total of 666 references; 580 were excluded and 20 articles met the inclusion criteria for the final analysis. Results. More studies supported the Pneumonia Severity Index (PSI as a superior predictor of NHAP severity. Fewer studies suggested CURB-65 and SOAR (especially for the need of ICU care as useful predictors for NHAP mortality. There is weak evidence for biomarkers like C-reactive protein and copeptin as prognostic tools. Conclusion. The evidence supports the use of PSI as the best available indicator while CURB-65 may be an alternative prognostic indicator for NHAP mortality. Overall, due to the paucity of information, biomarkers may not be as effective in this role. Larger prospective studies are needed to establish the most effective predictor(s or combination scheme to help clinicians in decision-making related to NHAP mortality.

    Full Text Available BACKGROUND: Hong Kong population has experienced drastic changes in its economic development in the 1940s. Taking advantage of Hong Kong's unique demographic and socioeconomic history, characterized by massive, punctuated migration waves from Southern China, and recent, rapid transition from a pre-industrialized society to the first ethnic Chinese community reaching "first world" status over the last 60 years (i.e., in two or three generations, we examined the longitudinal trends in infection related mortality including septicemia compared to trends in non-bacterial pneumonia to generate hypotheses for further testing in other recently transitioned economies and to provide generalized aetiological insights on how economic transition affects infection-related mortality. METHODS: We used deaths from septicemia and pneumonia not specified as bacterial, and population figures in Hong Kong from 1976-2005. We fitted age-period-cohort models to decompose septicemia and non-bacterial pneumonia mortality rates into age, period and cohort effects. RESULTS: Septicaemia-related deaths increased exponentially with age, with a downturn by period. The birth cohort curves had downward inflections in both sexes in the 1940s, with a steeper deceleration for women. Non-bacterial pneumonia-related deaths also increased exponentially with age, but the birth cohort patterns showed no downturns for those born in the 1940s. CONCLUSION: The observed changes appeared to suggest that better early life conditions may enable better development of adaptive immunity, thus enhancing immunity against bacterial infections, with greater benefits for women than men. Given the interaction between the immune system and the gonadotropic axis, these observations are compatible with the hypothesis that upregulation of the gonadotropic axis underlies some of the changes in disease patterns with economic development.

    Full Text Available Abstract In a previous study, we demonstrated prolonged length of hospital stay in cases of extended-spectrum beta-lactamase (ESBL-positive K. pneumoniae bacteremia compared to bacteremia cases due to E. coli (ESBL-positive and –negative and ESBL-negative K. pneumoniae. The overall mortality was significantly higher in bacteremia cases resulting from ESBL-positive pathogens but also in K. pneumoniae cases disregarding ESBL-production. In order to examine whether pathogen species rather than multidrug resistance might affect mortality risk, we reanalyzed our dataset that includes 1.851 cases of bacteremia.

    Full Text Available Abstract Background Pneumonia is a leading cause of children's deaths in developing countries and hinders achievement of the fourth Millennium Development Goal. This goal aims to reduce the under-five mortality rate, by two thirds, between 1990 and 2015. Few studies have examined the impact of zinc adjunct therapy on the outcome of childhood pneumonia. We determined the effect of zinc as adjunct therapy on time to normalization of respiratory rate, temperature and oxygen saturation. We also studied the effect of zinc adjunct therapy on case fatality of severe childhood pneumonia (as a secondary outcome in Mulago Hospital, Uganda. Methods In this double blind, randomized, placebo-controlled clinical trial, 352 children aged 6 to 59 months, with severe pneumonia were randomized to zinc (20 mg for children ≥12 months, and 10 mg for those Results Time to normalization of the respiratory rate, temperature and oxygen saturation was not significantly different between the two arms. Case fatality was 7/176 (4.0% in the zinc group and 21/176 (11.9% in the placebo group: Relative Risk 0.33 (95% CI 0.15 to 0.76. Relative Risk Reduction was 0.67 (95% CI 0.24 to 0.85, while the number needed to treat was 13. Among HIV infected children, case fatality was higher in the placebo (7/27 than in the zinc (0/28 group; RR 0.1 (95% CI 0.0, 1.0. Among 127 HIV uninfected children receiving the placebo, case fatality was 7/127 (5.5%; versus 5/129 (3.9% among HIV uninfected group receiving zinc: RR 0.7 (95% CI 0.2, 2.2. The excess risk of death attributable to the placebo arm (Absolute Risk Reduction or ARR was 8/100 (95% CI: 2/100, 14/100 children.

    Full Text Available Background: Childhood mortality in Ghana has generally declined in the last four decades. However, estimates tend to conceal substantial variability among regions and districts. The lack of population-based data in Ghana, as in other less developed countries, has hindered the development of effective programmes targeted specifically at clusters where mortality levels are significantly higher. Objective: This paper seeks to test for the existence of statistically significant clusters of childhood mortality within the Kintampo Health and Demographic Surveillance System (KHDSS between 2005 and 2007. Design: In this study, mortality rates were generated using mortality data extracted from the health and demographic surveillance database of the KHDSS and exported into STATA. The spatial and spatio-temporal scan statistic by Kulldorff was used to identify significant clusters of childhood mortality within the KHDSS. Results: A significant cluster of villages with high under-five mortality in the south-eastern part of the KHDSS in 2006 was identified. This is a remote location where poverty levels are relatively higher, health facilities are more sparse and these are compounded by poor transport services in case of emergencies. Conclusion: This study highlights the potential of the surveillance platform to demonstrate the spatial dimensions of childhood mortality clustering. It is apparent, though, that further studies need to be carried out in order to explore the underlying risk factors for potential mortality clusters that could emerge later.

    Ya-Tang Liao

    Full Text Available BACKGROUND: Pneumonia is one of most prevalent infectious diseases worldwide and is associated with considerable mortality. In comparison to general population, schizophrenia patients hospitalized for pneumonia have poorer outcomes. We explored the risk factors of short-term mortality in this population because the information is lacking in the literature. METHODS: In a nationwide schizophrenia cohort, derived from the National Health Insurance Research Database in Taiwan, that was hospitalized for pneumonia between 2000 and 2008 (n = 1,741, we identified 141 subjects who died during their hospitalizations or shortly after their discharges. Based on risk-set sampling in a 1∶4 ratio, 468 matched controls were selected from the study cohort (i.e., schizophrenia cohort with pneumonia. Physical illnesses were categorized as pre-existing and incident illnesses that developed after pneumonia respectively. Exposures to medications were categorized by type, duration, and defined daily dose. We used stepwise conditional logistic regression to explore the risk factors for short-term mortality. RESULTS: Pre-existing arrhythmia was associated with short-term mortality (adjusted risk ratio [RR] = 4.99, p<0.01. Several variables during hospitalization were associated with increased mortality risk, including incident arrhythmia (RR = 7.44, p<0.01, incident heart failure (RR = 5.49, p = 0.0183 and the use of hypoglycemic drugs (RR = 2.32, p<0.01. Furthermore, individual antipsychotic drugs (such as clozapine known to induce pneumonia were not significantly associated with the risk. CONCLUSIONS: Incident cardiac complications following pneumonia are associated with increased short-term mortality. These findings have broad implications for clinical intervention and future studies are needed to clarify the mechanisms of the risk factors.

    This study aimed to assess the association between climate factors and the incidence of childhood pneumonia in Papua New Guinea quantitatively and to evaluate the variability of the effect size according to their geographic properties. The pneumonia incidence in children under five-year and meteorological factors were obtained from six areas, including monthly rainfall and the monthly average daily maximum temperatures during the period from 1997 to 2006 from national health surveillance data. A generalized linear model was applied to measure the effect size of local and regional climate factor. The pooled risk of pneumonia in children per every 10 mm increase of rainfall was 0.24% (95% confidence interval: -0.01%-0.50%), and risk per every 1 °C increase of the monthly mean of the maximum daily temperatures was 4.88% (95% CI: 1.57-8.30). Southern oscillation index and dipole mode index showed an overall negative effect on childhood pneumonia incidence, -0.57% and -4.30%, respectively, and the risk of pneumonia was higher in the dry season than in the rainy season (pooled effect: 12.08%). There was a variability in the relationship between climate factors and pneumonia which is assumed to reflect distribution of the determinants of and vulnerability to pneumonia in the community.

    The influence of pneumonia in acute stroke stage on the clinical presentation and long-term outcomes of patients with acute ischemic stroke is still controversial. We investigate the influence of pneumonia in acute stroke stage on the 3-year outcomes of patients with acute first-ever ischemic stroke. Nine-hundred and thirty-four patients with acute first-ever ischemic stroke were enrolled and had been followed for 3years. Patients were divided into two groups according to whether pneumonia occurred during acute stroke stage or not. Clinical presentations, risk factors for stroke, laboratory data, co-morbidities, and outcomes were recorded. The result showed that a total of 100 patients (10.7%) had pneumonia in acute stroke stage. The prevalence of older age, atrial fibrillation was significantly higher in patients with pneumonia in acute stroke stage. Total anterior circulation syndrome and posterior circulation syndrome occurred more frequently among patients with pneumonia in acute stroke stage (Ppneumonia in acute stroke stage is a significant predictor of 3-year mortality (hazard ratio=6.39, 95% confidence interval=4.03-10.11, Ppneumonia during the acute stroke stage is associated with increased risk of 3-year mortality.

    Full Text Available Abstract Background This study aimed to determine the out-of pocket expenditure and coping strategies adopted by families of children admitted in a hospital in Bangladesh with pneumonia. Methods Trained interviewers surveyed parents of 90 children and conducted in-depth interviews with six families below the age of 5 years who were admitted to the largest pediatric hospital in Bangladesh with a diagnosis of pneumonia. We estimated the total cost of illness associated with hospitalization and explored the coping strategies of the families. Results The mean expenditure of the families for the illness episode was US$ 94 (±SD 52.5 with 75% having spent more than half of their total monthly expenditure on this hospitalization. Three fourths (68/90, 76% of the families managed the expenditure by borrowing, mortgaging or selling assets; 64% had to borrow the full cost of hospitalization and 10% borrowed from the formal sector with a monthly interest rate of 5 to 30%. The burden was highest for the people from poor income strata. Families earning ≤US$ 59 per month were 10 times more likely than families earning ≥US$ 59 per month to borrow money (OR = 10.0, 95% CI: 2.8-38.8. To repay their debts, 22% of families reported that they would work extra hours and 50% planned to reduce spending on food and education for their children. Conclusions Coping strategies adopted by the families to manage the out-of-pocket expenditure for children requiring hospitalization were catastrophic for the majority of the families. Efforts to prevent childhood pneumonia for example, by vaccination against the most common pathogens, by improving air quality and by improving childhood nutrition can provide a double advantage. They can prevent both disease and poverty.

    Full Text Available Background: Assessing the progress in achieving the United Nation's Millennium Development Goals in terms of population health requires consistent and reliable information on cause-specific mortality, which is often rare in resource-constrained countries. Health and demographic surveillance systems (HDSS have largely used medical personnel to review and assign likely causes of death based on the information gathered from standardized verbal autopsy (VA forms. However, this approach is expensive and time consuming, and it may lead to biased results based on the knowledge and experience of individual clinicians. We assessed the cause-specific mortality for children under 5 years old (under-5 deaths in Siaya County, obtained from a computer-based probabilistic model (InterVA-4. Design: Successfully completed VA interviews for under-5 deaths conducted between January 2003 and December 2010 in the Kenya Medical Research Institute/US Centers for Disease Control and Prevention HDSS were extracted from the VA database and processed using the InterVA-4 (version 4.02 model for interpretation. Cause-specific mortality fractions were then generated from the causes of death produced by the model. Results: A total of 84.33% (6,621 childhood deaths had completed VA data during the study period. Children aged 1–4 years constituted 48.53% of all cases, and 42.50% were from infants. A single cause of death was assigned to 89.18% (5,940 of cases, 8.35% (556 of cases were assigned two causes, and 2.10% (140 were assigned ‘indeterminate’ as cause of death by the InterVA-4 model. Overall, malaria (28.20% was the leading cause of death, followed by acute respiratory infection including pneumonia (25.10%, in under-5 children over the study period. But in the first 5 years of the study period, acute respiratory infection including pneumonia was the main cause of death, followed by malaria. Similar trends were also reported in infants (29 days–11 months and

    Arsenic in drinking water is an established cause of lung, bladder, and skin cancers in adults and may also cause adult kidney and liver cancers. Some evidence for these effects originated from region II of Chile, which had a period of elevated arsenic levels in drinking water, in particular from 1958 to 1970. This unique exposure scenario provides a rare opportunity to investigate the effects of early-life arsenic exposure on childhood mortality; to our knowledge, this is the first study of childhood cancer mortality and high concentrations of arsenic in drinking water. In this article, we compare cancer mortality rates under the age of 20 in region II during 1950 to 2000 with those of unexposed region V, dividing subjects into those born before, during, or after the peak exposure period. Mortality from the most common childhood cancers, leukemia and brain cancer, was not increased in the exposed population. However, we found that childhood liver cancer mortality occurred at higher rates than expected. For those exposed as young children, liver cancer mortality between ages 0 and 19 was especially high: the relative risk (RR) for males born during this period was 8.9 [95% confidence interval (95% CI), 1.7-45.8; P = 0.009]; for females, the corresponding RR was 14.1 (95% CI, 1.6-126; P = 0.018); and for males and females pooled, the RR was 10.6 (95% CI, 2.9-39.2; P water during early childhood may result in an increase in childhood liver cancer mortality.

Although ICS has been reported to increase the risk of pneumonia in patients with COPD, it remains controversial whether it influences mortality. Using a Japanese national database, we examined the association between preadmission ICS therapy and in-hospital mortality from pneumonia in patients with COPD. Methods: We retrospectively collected data from 1,165 hospitals in Japan on patients with COPD who received outpatient inhalation therapy and were admitted with pneumonia. Patients were categorized into those who received ICS with IBD and those who received IBD alone. We performed multivariate logistic regression analysis to examine the association between outpatient ICS therapy and in-hospital mortality, adjusting for the patients’ backgrounds. Results: Of the 7,033 eligible patients, the IBD alone group (n=3,331 was more likely to be older, have lower body mass index, poorer general conditions, and more severe pneumonia than the ICS with IBD group (n=3,702. In-hospital mortality was 13.2% and 8.1% in the IBD alone and the ICS with IBD groups, respectively. After adjustment for patients’ backgrounds, the ICS with IBD group had significantly lower mortality than the IBD alone group (adjusted odds ratio, 0.80; 95% confidence interval, 0.68–0.94. Higher mortality was associated with older age, being male

    Analysis of cancer incidence, mortality, and survival rates can yield geographic and temporal trends that are useful for planning and evaluating health interventions. This article reviews cancer incidence and mortality rates and respective trends around the world in children under 15 years old, as well as their 5-year survival rates in developed and developing countries. We conclude that even though increasing or stable childhood cancer incidence rates and decreasing mortality rates have been observed in developed countries, the trends remain unknown in developing countries. Data from the city of Goiania, Brazil, show stable childhood cancer incidence and mortality rates. Five-year survival rates (48%) in Goiania are similar to those seen in underdeveloped regions and lower than those reported in developed countries (64-70%).

    Recurrent pneumonia (RP) within 12 months is one of the AIDS diagnosis criteria. To gain knowledge of RP infection in HIV-infected patients, we studied 145 RP cases detected in a cohort of 2,996 HIV patients in Puerto Rico between Jan. 1992-Dec. 2001. The RP prevalence was 4.8%; 77.2% were males and 62.1% were injecting drug users (IDU). At the time of RP diagnosis, the mean CD4+ T cell count was 93.8 cells/mm3, 59.3% were in antiretroviral treatment, 13% had received the pneumococcal vaccine and 84.8% had another AIDS related condition. Over 37% received two or more antiretroviral medications. The death rate in the first year after the RP diagnosis was 63.4%. A Cox proportional hazard analysis showed that CD4+ T cells vaccination percent at the time of RP diagnosis. Low CD4+ T cells significantly increased the hazard and mortality risk of the cases studied. Antecedents of antiretroviral therapy in these patients ensure a better outcome with lower mortality. Efforts to increase the vaccination rate should reduce the RP incidence in our HIV-infected population.

    According to World Health Organization, pneumonia is the respiratory disease with the highest pediatric mortality rate accounting for 15% of all deaths of children under 5 years old worldwide. The diagnosis of pneumonia is commonly made by clinical criteria with support from ancillary studies and also laboratory findings. Chest imaging is commonly done with chest X-rays and occasionally with a chest CT scan. Lung ultrasound is a promising alternative for chest imaging; however, interpretation is subjective and requires adequate training. In the present work, a two-class classification algorithm based on four Gray-level co-occurrence matrix texture features (i.e., Contrast, Correlation, Energy and Homogeneity) extracted from lung ultrasound images from children aged between six months and five years is presented. Ultrasound data was collected using a L14-5/38 linear transducer. The data consisted of 22 positive- and 68 negative-diagnosed B-mode cine-loops selected by a medical expert and captured in the facilities of the Instituto Nacional de Salud del Niño (Lima, Peru), for a total number of 90 videos obtained from twelve children diagnosed with pneumonia. The classification capacity of each feature was explored independently and the optimal threshold was selected by a receiver operator characteristic (ROC) curve analysis. In addition, a principal component analysis was performed to evaluate the combined performance of all the features. Contrast and correlation resulted the two more significant features. The classification performance of these two features by principal components was evaluated. The results revealed 82% sensitivity, 76% specificity, 78% accuracy and 0.85 area under the ROC.

    Reported are the results of a case-control study carried out between July 1989 and June 1990 in Fortaleza city, Ceará State, Brazil, to determine the factors that place young children living in urban slum conditions at increased risk of contracting pneumonia. Cases were 650 under-2-year-olds with a radiological diagnosis of pneumonia who were recruited at the main paediatric hospital in the city over a full calendar year. Age-matched controls were recruited from the neighbourhood where the cases lived. Cases and controls were compared with respect to a variety of sociodemographic, environmental, reproductive, nutritional, and morbidity factors, and a risk factor questionnaire was administered to the mother of each child or to the child's normal guardian. Cases and controls were also weighed and measured. Malnutrition was the most important risk factor for childhood pneumonia in the study population, with weight-for-age, height-for-age, and weight-for-height also being important risk factors. In view of the high prevalence of stunting in the study population, there is an urgent need to reduce the level of malnutrition as a priority. Attendance at a day care centre was also associated with a high odds ratio. In view of the growing numbers of children attending day care centres in both developing and developed countries, it is essential that ways be identified to improve the design and management of such centres in order to minimize the risk of pneumonia. Increased risks of childhood pneumonia were also associated with low birth weight, non-breast-feeding, crowding, high parity, and incomplete vaccination status, but not with socioeconomic status or environmental variables. Finally, children who had suffered from previous episodes of wheezing or been hospitalized for pneumonia had a greater than threefold increased risk of contracting the disease.

  14. Child mortality estimation: estimating sex differences in childhood mortality since the 1970s.

    Full Text Available INTRODUCTION: Producing estimates of infant (under age 1 y, child (age 1-4 y, and under-five (under age 5 y mortality rates disaggregated by sex is complicated by problems with data quality and availability. Interpretation of sex differences requires nuanced analysis: girls have a biological advantage against many causes of death that may be eroded if they are disadvantaged in access to resources. Earlier studies found that girls in some regions were not experiencing the survival advantage expected at given levels of mortality. In this paper I generate new estimates of sex differences for the 1970s to the 2000s. METHODS AND FINDINGS: Simple fitting methods were applied to male-to-female ratios of infant and under-five mortality rates from vital registration, surveys, and censuses. The sex ratio estimates were used to disaggregate published series of both-sexes mortality rates that were based on a larger number of sources. In many developing countries, I found that sex ratios of mortality have changed in the same direction as historically occurred in developed countries, but typically had a lower degree of female advantage for a given level of mortality. Regional average sex ratios weighted by numbers of births were found to be highly influenced by China and India, the only countries where both infant mortality and overall under-five mortality were estimated to be higher for girls than for boys in the 2000s. For the less developed regions (comprising Africa, Asia excluding Japan, Latin America/Caribbean, and Oceania excluding Australia and New Zealand, on average, boys' under-five mortality in the 2000s was about 2% higher than girls'. A number of countries were found to still experience higher mortality for girls than boys in the 1-4-y age group, with concentrations in southern Asia, northern Africa/western Asia, and western Africa. In the more developed regions (comprising Europe, northern America, Japan, Australia, and New Zealand, I found

    Full Text Available Prediction of patient-centered outcomes in hospitals is useful for performance benchmarking, resource allocation, and guidance regarding active treatment and withdrawal of care. Yet, their use by clinicians is limited by the complexity of available tools and amount of data required. We propose to use Disjunctive Normal Forms as a novel approach to predict hospital and 90-day mortality from instance-based patient data, comprising demographic, genetic, and physiologic information in a large cohort of patients admitted with severe community acquired pneumonia. We develop two algorithms to efficiently learn Disjunctive Normal Forms, which yield easy-to-interpret rules that explicitly map data to the outcome of interest. Disjunctive Normal Forms achieve higher prediction performance quality compared to a set of state-of-the-art machine learning models, and unveils insights unavailable with standard methods. Disjunctive Normal Forms constitute an intuitive set of prediction rules that could be easily implemented to predict outcomes and guide criteria-based clinical decision making and clinical trial execution, and thus of greater practical usefulness than currently available prediction tools. The Java implementation of the tool JavaDNF will be publicly available.

    Community-acquired pneumonia (CAP) is a leading cause of adult morbidity and mortality worldwide despite decades of effective antibiotics and vaccination initiatives. There have been no recent significant improvements in outcomes, including 30-day mortality. The bacterium Streptococcus pneumoniae is the most prevalent causative pathogen in CAP, being found in up to half of cases. In September 2006 a childhood pneumococcal vaccine (PCV-7) was introduced, leading to reductions in vaccine-type (...

    Full Text Available Abstract Background A better understanding of potentially modifiable predictors of in-hospital mortality and re-admission to the hospital following discharge may help to improve management of community-acquired pneumonia in older adults. We aimed to assess the associations of potentially modifiable factors with mortality and re-hospitalization in older adults hospitalized with community-acquired pneumonia. Methods A prospective cohort study was conducted from July 2003 to April 2005 in two Canadian cities. Patients aged 65 years or older hospitalized for community-acquired pneumonia were followed up for up to 30 days from initial hospitalization for mortality and these patients who were discharged alive within 30 days of initial hospitalization were followed up to 90 days of initial hospitalization for re-hospitalization. Separate logistic regression analyses were performed identify the predictors of mortality and re-hospitalization. Results Of 717 enrolled patients hospitalized for community-acquired pneumonia, 49 (6.8% died within 30 days of hospital admission. Among these patients, 526 were discharged alive within 30 days of hospitalization of whom 58 (11.2% were re-hospitalized within 90 days of initial hospitalization. History of hip fracture (odds ratio (OR = 4.00, 95% confidence interval (CI = (1.46, 10.96, P = .007, chronic obstructive pulmonary disease (OR = 2.31, 95% CI = (1.18, 4.50, P = .014, cerebrovascular disease (OR = 2.11, 95% CI = (1.03, 4.31, P = .040 were associated with mortality.

    To evaluate the relationship between carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) gut colonization and mortality in diabetic patients with a foot infection (DFI) we performed a single-centre, retrospective, matched case-control study. In the study period, we identified 21 patients with DFI who had KPC-Kp gut colonization and 21 controls. The 90-day mortality rate was significantly higher in patients with colonized guts (47%) than the controls (4%) (p 0.013). A multivariate analysis demonstrated that gut colonization with KPC-Kp was the only independent predictor of mortality: odds ratio 13.33, 95% CI 1.90-272.80, p 0.024. In patients with DFI, KPC-Kp gut colonization appears to be an important risk factor for mortality.

    The 7-valent pneumococcal conjugate vaccine (PCV7) is reported to decrease the incidence of community-acquired pneumonia (CAP) in children. To determine the annual incidence of CAP before the introduction of PCV7, we counted the number of children hospitalized with CAP between 2008 and 2009 in Chiba City, Japan. We investigated serotype and multilocus sequence typing (MLST) for Streptococcus pneumoniae isolates in CAP cases. The annual incidence of hospitalized CAP in children aged pneumoniae was dominant in 14.7% and 0.8% of sputum and blood samples, respectively. The most common serotypes were 6B, 23F and 19F. The coverage rates of PCV7 were 66.7% and 80% in sputum samples and blood samples, respectively. MLST analysis revealed 37 sequence types. Furthermore, 54.1% of the sputum isolates and 40% of the blood isolate were related to international multidrug-resistant clones.

    Hrdlicka ([1914] Smithson. Inst. Misc. Collect. 61:1-69) reported that pre-Columbian skeletal material from the coastal lowland Andean region exhibited a high frequency of porotic hyperostosis, a pathological condition of bone that generally is thought to indicate childhood anemia. While subsequent studies tended to reinforce this conclusion, factors implicated in the condition have yet to be fully explored in the region as a whole. This study explores regional and intravalley variation as one step in establishing biocultural variables that increase the apparent risk of childhood anemia. The study sample includes 1,465 individuals: 512 from Peruvian collections housed at the Field Museum of Natural History, and 953 from systematically excavated contexts from Moquegua, Peru. Environmental stressors, such as parasites and disease, rather than specific dietary practices were found to be more likely associated with childhood anemia in these coastal Andean samples. The study supports cribra orbitalia as an earlier expression of porotic hyperostosis and suggests that porotic hyperostosis, as recorded here, cannot be easily dismissed as a result of cranial shape modification. No clear temporal patterns were observed. Finally, the study establishes that comparing data for children and adults can reveal the relative association between childhood anemia and mortality. Childhood mortality associated with anemia was elevated where the presence of tuberculosis or tuberculosis-like conditions was more common and the presence of water-borne pathogens was negligible. In contrast, those buried at lower altitudes, closer to the coast, and consuming mainly marine resources were less likely to die in childhood with anemia than in the other contexts studied.

    Background Following the adoption of the Millennium Development Goal 4 (MDG 4) in Ghana to reduce under-five mortality by two-thirds between 1990 and 2015, efforts were made towards its attainment. However, impacts and challenges of implemented intervention programs have not been examined to inform implementation of Sustainable Development Goal 3.2 (SDG 3.2) that seeks to end preventable deaths of newborns and children aged under-five. Thus, this study aimed to compare trends in neonatal, infant, and under-five mortality over two decades and to highlight the impacts and challenges of health policies and intervention programs implemented. Design Ghana Demographic and Health Survey data (1988–2008) were analyzed using trend analysis. Poisson regression analysis was applied to quantify the incidence rate ratio of the trends. Implemented health policies and intervention programs to reduce childhood mortality in Ghana were reviewed to identify their impact and challenges. Results Since 1988, the annual average rate of decline in neonatal, infant, and under-five mortality in Ghana was 0.6, 1.0, and 1.2%, respectively. From 1988 to 1989, neonatal, infant, and under-five mortality declined from 48 to 33 per 1,000, 72 to 58 per 1,000, and 108 to 83 per 1,000, respectively, whereas from 1989 to 2008, neonatal mortality increased by 2 per 1,000 while infant and under-five mortality further declined by 6 per 1,000 and 17 per 1,000, respectively. However, the observed declines were not statistically significant except for under-five mortality; thus, the proportion of infant and under-five mortality attributed to neonatal death has increased. Most intervention programs implemented to address childhood mortality seem not to have been implemented comprehensively. Conclusion Progress towards attaining MDG 4 in Ghana was below the targeted rate, particularly for neonatal mortality as most health policies and programs targeted infant and under-five mortality. Implementing neonatal

    Full Text Available Abstract Background Where hard-to-access populations (such as those living in insecure areas lack access to basic health services, relief agencies, donors, and ministries of health face a dilemma in selecting the most effective intervention strategy. This paper uses a decision mathematical model to estimate the relative effectiveness of two alternative strategies, mobile clinics and fixed community-based health services, for antibiotic treatment of childhood pneumonia, the world's leading cause of child mortality. Methods A "Markov cycle tree" cohort model was developed in Excel with Visual Basic to compare the number of deaths from pneumonia in children aged 1 to 59 months expected under three scenarios: 1 No curative services available, 2 Curative services provided by a highly-skilled but intermittent mobile clinic, and 3 Curative services provided by a low-skilled community health post. Parameter values were informed by literature and expert interviews. Probabilistic sensitivity analyses were conducted for several plausible scenarios. Results We estimated median pneumonia-specific under-5 mortality rates of 0.51 (95% credible interval: 0.49 to 0.541 deaths per 10,000 child-days without treatment, 0.45 (95% CI: 0.43 to 0.48 with weekly mobile clinics, and 0.31 (95% CI: 0.29 to 0.32 with CHWs in fixed health posts. Sensitivity analyses found the fixed strategy superior, except when mobile clinics visited communities daily, where rates of care-seeking were substantially higher at mobile clinics than fixed posts, or where several variables simultaneously differed substantially from our baseline assumptions. Conclusions Current evidence does not support the hypothesis that mobile clinics are more effective than CHWs. A CHW strategy therefore warrants consideration in high-mortality, hard-to-access areas. Uncertainty remains, and parameter values may vary across contexts, but the model allows preliminary findings to be updated as new or context

    Ana Carolina Souza-Oliveira

    Full Text Available Abstract Ventilator-associated pneumonia is the most prevalent nosocomial infection in intensive care units and is associated with high mortality rates (14–70%. Aim This study evaluated factors influencing mortality of patients with Ventilator-associated pneumonia (VAP, including bacterial resistance, prescription errors, and de-escalation of antibiotic therapy. Methods This retrospective study included 120 cases of Ventilator-associated pneumonia admitted to the adult adult intensive care unit of the Federal University of Uberlândia. The chi-square test was used to compare qualitative variables. Student's t-test was used for quantitative variables and multiple logistic regression analysis to identify independent predictors of mortality. Findings De-escalation of antibiotic therapy and resistant bacteria did not influence mortality. Mortality was 4 times and 3 times higher, respectively, in patients who received an inappropriate antibiotic loading dose and in patients whose antibiotic dose was not adjusted for renal function. Multiple logistic regression analysis revealed the incorrect adjustment for renal function was the only independent factor associated with increased mortality. Conclusion Prescription errors influenced mortality of patients with Ventilator-associated pneumonia, underscoring the challenge of proper Ventilator-associated pneumonia treatment, which requires continuous reevaluation to ensure that clinical response to therapy meets expectations.

    Full Text Available To measure mortality and its risk factors among children discharged from a health centre in rural Gambia.We conducted a cohort study between 12 May 2008 and 11 May 2012. Children aged 2-59 months, admitted with suspected pneumonia, sepsis, or meningitis after presenting to primary and secondary care facilities, were followed for 180 days after discharge. We developed models associating post-discharge mortality with clinical syndrome on admission and clinical risk factors.One hundred and five of 3755 (2.8% children died, 80% within 3 months of discharge. Among children aged 2-11 and 12-59 months, there were 30 and 29 deaths per 1000 children per 180 days respectively, compared to 11 and 5 respectively in the resident population. Children with suspected pneumonia unaccompanied by clinically severe malnutrition (CSM had the lowest risk of post-discharge mortality. Mortality increased in children with suspected meningitis or septicaemia without CSM (hazard ratio [HR] 2.6 and 2.2 respectively. The risk of mortality greatly increased with CSM on admission: CSM with suspected pneumonia (HR 8.1; 95% confidence interval (CI 4.4 to 15, suspected sepsis (HR 18.4; 95% CI 11.3 to 30, or suspected meningitis (HR 13.7; 95% CI 4.2 to 45.

    Full Text Available BACKGROUND: Bereavement by spousal death and child death in adulthood has been shown to lead to an increased risk of mortality. Maternal death in infancy or parental death in early childhood may have an impact on mortality but evidence has been limited to short-term or selected causes of death. Little is known about long-term or cause-specific mortality after parental death in childhood. METHODS AND FINDINGS: This cohort study included all persons born in Denmark from 1968 to 2008 (n = 2,789,807 and in Sweden from 1973 to 2006 (n = 3,380,301, and a random sample of 89.3% of all born in Finland from 1987 to 2007 (n = 1,131,905. A total of 189,094 persons were included in the exposed cohort when they lost a parent before 18 years old. Log-linear Poisson regression was used to estimate mortality rate ratio (MRR. Parental death was associated with a 50% increased all-cause mortality (MRR = 1.50, 95% CI 1.43-1.58. The risks were increased for most specific cause groups and the highest MRRs were observed when the cause of child death and the cause of parental death were in the same category. Parental unnatural death was associated with a higher mortality risk (MRR = 1.84, 95% CI 1.71-2.00 than parental natural death (MRR = 1.33, 95% CI 1.24-1.41. The magnitude of the associations varied according to type of death and age at bereavement over different follow-up periods. The main limitation of the study is the lack of data on post-bereavement information on the quality of the parent-child relationship, lifestyles, and common physical environment. CONCLUSIONS: Parental death in childhood or adolescence is associated with increased all-cause mortality into early adulthood. Since an increased mortality reflects both genetic susceptibility and long-term impacts of parental death on health and social well-being, our findings have implications in clinical responses and public health strategies.

    Objectives Preconception maternal bereavement may be associated with an increased risk for infant mortality, though these previously reported findings have not been replicated. We sought to examine if the association could be replicated and explore if risk extended into childhood. Methods Using a Danish population-based sample of offspring born 1979–2009 (N=1,865,454), we predicted neonatal (0–28 days), post-neonatal infant (29–364 days), and early childhood (1–5 years) mortality following maternal bereavement in the preconception (6–0 months before pregnancy) and prenatal (between conception and birth) periods. Maternal bereavement was defined as death of a first degree relative of the mother. Analyses were conducted using logistic and log-linear Poisson regression that were adjusted for offspring, mother, and father sociodemographic and health factors. Results We identified 6,541 (0.004%) neonates, 3,538 (0.002%) post-neonates, and 2,132 (0.001%) children between the ages of 1 to 5 years who died. After adjusting for covariates, bereavement during the preconception period was associated with an increased odds of neonatal (adjusted odds ratio [aOR] = 1.87, 95% CI: 1.53–2.30) and post-neonatal infant mortality (aOR=1.52, 95% CI: 1.15–2.02). Associations were timing-specific (6 months prior to pregnancy only) and consistent across sensitivity analyses. Bereavement during the prenatal period was not consistently associated with increased risk of offspring mortality, however this may reflect relatively low statistical power. Conclusions Results support and extend previous findings linking bereavement during the preconception period with increased odds of early offspring mortality. The period immediately prior to pregnancy may be a sensitive period with potential etiological implications and ramifications for offspring mortality. PMID:26374948

  9. The global burden of childhood coeliac disease: a neglected component of diarrhoeal mortality?

    Directory of Open Access Journals (Sweden)

    Peter Byass

    Full Text Available OBJECTIVES: Coeliac disease has emerged as an increasingly recognised public health problem over the last half-century, and is now coming to be seen as a global phenomenon, despite a profound lack of globally representative epidemiological data. Since children with coeliac disease commonly present with chronic diarrhoea and malnutrition, diagnosis is often overlooked, particularly in poorer settings where children often fail to thrive and water-borne infectious diarrhoeas are common. This is the first attempt to make global estimates of the burden of coeliac disease in childhood. METHODS: We built a relatively crude model of childhood coeliac disease, incorporating estimates of population prevalence, probability of non-diagnosis, and likelihood of mortality among the undiagnosed across all countries from 1970 to 2010, based around the few available data. All our assumptions are stated in the paper and the model is available as a supplementary file. FINDINGS: Our model suggests that in 2010 there were around 2.2 million children under 5 years of age living with coeliac disease. Among these children there could be 42,000 deaths related to coeliac disease annually. In 2008, deaths related to coeliac disease probably accounted for approximately 4% of all childhood diarrhoeal mortality. CONCLUSIONS: Although coeliac disease may only account for a small proportion of diarrhoeal mortality, these deaths are not preventable by applying normal diarrhoea treatment guidelines, which may even involve gluten-based food supplements. As other causes of diarrhoeal mortality decline, coeliac disease will become a proportionately increasing problem unless consideration is given to trying gluten-free diets for children with chronic diarrhoea and malnutrition.

    The present study was aimed at assessing differences between the Nordic countries, if any, in late mortality among five-year survivors of childhood cancer. All cases diagnosed before the age of 20 years, between 1960 and 1989, were collected from all Nordic cancer registries. In total, 13,689 patients were identified as five-year survivors and during the extended follow-up 12.3% of them died. Mortality was analysed by decade of diagnosis, for all sites, and for leukaemia, Hodgkin's lymphoma, and central nervous system tumours separately. Analyses were done within a Cox proportional hazards regression framework with adjustments made for gender and age at diagnosis. Hazard ratios were calculated in relation to a weighted Nordic mean based on the proportion of five-year survivors in each country. Overall late mortality was significantly higher in Denmark and Finland than in Norway and Sweden. This could not be explained by inverse differences in five-year survival. The differences diminished over time and had disappeared in the last period. The pattern was similar for both genders. The disappearance of the differences was most probably the effect of a closer collaboration between Nordic paediatric oncologists with development and implementation of common protocols for treatment of childhood cancers in all countries.

    Full Text Available Varicella is one of the most contagious diseases of childhood. Whenever varicella is seen in adults, it can cause serious complications. Pneumonia is one of the most serious complications of varicella during adulthood and it has a high mortality rate. Cases of varicella pneumonia which need mechanical ventilation in intensive care unit, have %50 of mortality rate.This report presents a patient who was diagnosed as varicella pneumonia in our intensive care unit. Our treatment and diagnostic approach is presented together with actual literature.

  12. Spatial analysis of the relationship between early childhood mortality and malaria endemicity in Malawi

    Full Text Available Spatial differences in mortality have been reported in Africa amongst children under-five years of age. Risk factors contributing to this geographical variation include bio-demographic and socio-economic factors, the prevalence of infectious diseases and the variability in the quality of child health care. This paper is concerned with investigating the link between early childhood mortality and malaria risk. We used data from the Mapping Malaria Risk in Africa (MARA and Demographic and Health Survey (DHS databases to explore this relationship. The DHS survey included questions on bio-demographic and socio-economic status, complete birth histories and survival time of each child within the five years preceding the survey. Survival times were computed in months until death or until the survey was done. The malaria risk was based on prevalence data estimated at the precise DHS sampling location. A spatial Cox regression model was applied to analyze child survival, assessing the influence of both individual-specific factors, malaria endemicity and group-specific environmental factors, approximated by geographical location. Geographical location was considered at subdistrict level. Our analysis shows that although malaria endemicity is not associated with the risk of infant mortality, it is an important risk factor for child mortality. The results confirm the effects of bio-demographic and socio-economic variables (maternal education, maternal age, birth order and place of residence on infant and child mortality. The subdistrict-specific variation of infant and child mortality shows a rural-urban distinction with a relatively lower risk of mortality in main urban areas.

    Objective To examine whether diabetes mellitus increases the risk of pneumonia mortality among seniors in the U.S. general popula-tion. Methods&Results The NHANES III follow-up study data were used. After excluding individuals from other minorities, being hos-pitalized with pneumonia in the previous year at baseline, or death of pneumonia during the first year of follow-up, a total of 3,707 subjects aged 65 years or older (1,794 men and 1,913 women) who had no missing information on variables for the analysis were included. Approxi-mately 16% of seniors at baseline were diabetics, which was defined as either having been diagnosed by a physician, currently taking pills/insulin lowering blood glucose, or HbA1c higher than 6.4%. During an average 11 years of follow-up, a total of 98 deaths due to pneu-monia were recorded (ICD-10:J12-J18). Cox-regression models were used to estimate the risk association between pneumonia mortality and diabetes mellitus. After adjustment for the covariates at baseline, the hazard ratios of pneumonia death were 1.30 (95%CI:0.64-2.70) for pre-diabetics and 2.28 (95%CI:1.18-4.39) for diabetics, respectively. Among those covariates, only age (HR (95%CI);1.16 (1.13-1.20)), gender as female (0.35 (0.22-0.61)) and physical fitness measured as having no problem walking 1+mile during the previous month (0.38 (0.20-0.67)) reached statistical significance. Conclusions The results suggest that diabetes mellitus is a strong risk predictor of pneumonia mortality and the evaluation of physical fitness may also be useful in the risk prediction of pneumonia mortality for seniors.

    Full Text Available An association between pneumococcal serotypes and mortality has been suggested. We aimed to investigate this among individuals aged ≥15 years with invasive pneumococcal disease (IPD in South Africa.IPD cases were identified through national laboratory-based surveillance at 25 sites, pre-pneumococcal conjugate vaccine (PCV introduction, from 2003-2008. We assessed the association between the 20 commonest serotypes and in-hospital mortality using logistic regression with serotype 4 (the third commonest serotype with intermediate case-fatality ratio (CFR as referent.Among 3953 IPD cases, CFR was 55% (641/1166 for meningitis and 23% (576/2484 for bacteremia (p<0.001. Serotype 19F had the highest CFR (48%, 100/207, followed by serotype 23F (39%, 99/252 and serotype 1 (38%, 246/651. On multivariable analysis, factors independently associated with mortality included serotype 1 (OR 1.9, 95%CI 1.1-3.5 and 19F (OR 2.9, 95%CI 1.4-6.1 vs. serotype 4; increasing age (25-44 years, OR 1.8, 95%CI 1.0-3.0; 45-64 years, OR 3.6, 95%CI 2.0-6.4; ≥65 years, OR 5.2, 95%CI 1.9-14.1; vs. 15-24 years; meningitis (OR 4.1, 95%CI 3.0-5.6 vs. bacteremic pneumonia; and HIV infection (OR1.7, 95%CI 1.0-2.8. On stratified multivariate analysis, serotype 19F was associated with increased mortality amongst bacteremic pneumococcal pneumonia cases, while no serotype was associated with increased mortality in meningitis cases.Mortality was increased in HIV-infected individuals, which may be reduced by increased antiretroviral therapy availability. Serotypes associated with increased mortality are included in the 10-and-13-valent PCV and may become less common in adults due to indirect effects following routine infant immunization.

    2013-06-01

    Full Text Available Type 1 diabetes with onset in childhood (0-14.9 years represents one of the most frequent chronic diseases in children and young adults. Norway has one of the highest incidences of childhood onset type 1 diabetes in the world. Before introduction of insulin therapy in 1922, few children survived more than one to two years after clinical onset. When insulin came available, a major shift occurred in the distribution of causes of death in type 1 diabetic patients away from diabetic coma, which dominated the pre-insulin era, to renal and cardiac diseases. The disease is related to a significant burden to society and patients because most cases require lifelong treatment with insulin as well as day-to-day monitoring. Type 1 diabetes also confers increased risk of severe late complications such as renal failure, blindness, amputations, heart disease and stroke. Despite advances in diabetes treatment, type 1 diabetes is still associated with considerable premature mortality resulting from acute and chronic complications of diabetes and an increase in mortality at every age. Although the main cause of death in type 1 diabetes is long-term complications, an excess death rate has also been reported in subjects with short duration without signs of long-term complications.

    The objectives of the study were to compare the effect of intensified oral care interventions given by dental or nursing personnel on mortality from healthcare-associated pneumonia (HAP) in elderly adults in hospitals or nursing homes with the effect of usual oral care. Systematic literature searches were conducted in PubMed, the Cochrane Library, and the Health Technology Assessment database of the National Health Service Centre for Reviews and Dissemination (August 2015). Randomized controlled trials (RCTs) were considered for inclusion. Data were extracted and risk of bias was assessed independently and agreed on in consensus meetings. Five RCTs, with some or major study limitations, fulfilled the inclusion criteria. Based on meta-analyses, oral care interventions given by dental personnel reduced mortality from HAP (risk ratio (RR) = 0.43, 95% confidence interval (CI) = 0.25-0.76, P = .003), whereas oral care interventions given by nursing personnel did not result in a statistically significant difference in mortality from HAP (RR = 1.20, 95% CI = 0.97-1.48, P = .09), in elderly adults in hospitals or nursing homes from usual oral care. Oral care interventions given by dental personnel may reduce mortality from HAP (low certainty of evidence, Grading of Recommendations Assessment, Development and Evaluation (GRADE) ⊕⊕○○), whereas oral care interventions given by nursing personnel probably result in little or no difference from usual care (moderate certainty of evidence, GRADE ⊕⊕⊕○) in elderly adults in hospitals or nursing homes.

    Carbapenemase-producing Klebsiella pneumoniae strains (CP-Kps) are currently among the most important nosocomial pathogens. An observational study was conducted during 2009 to 2010 in two hospitals located in a high-prevalence area (Athens, Greece). The aims were (i) to evaluate the clinical outcome of patients with CP-Kp bloodstream infections (BSIs), (ii) to identify predictors of mortality, and (iii) to evaluate the various antibiotic schemes employed. A total of 205 patients with CP-Kp BSIs were identified: 163 (79.5%) were infected with KPC or KPC and VIM, and 42 were infected with VIM producers. For definitive treatment, 103 patients received combination therapy (two or more active drugs), 72 received monotherapy (one active drug), and 12 received therapy with no active drug. The remaining 18 patients died within 48 h after the onset of bacteremia. The all-cause 28-day mortality was 40%. A significantly higher mortality rate was observed in patients treated with monotherapy than in those treated with combination therapy (44.4% versus 27.2%; P=0.018). The lowest mortality rate (19.3%) was observed in patients treated with carbapenem-containing combinations. In the Cox proportion hazards model, ultimately fatal disease (hazards ratio [HR], 3.25; 95% confidence interval [CI], 1.51 to 7.03; P=0.003), the presence of rapidly fatal underlying diseases (HR, 4.20; 95% CI, 2.19 to 8.08; Pcarbapenem-containing regimens.

    Background The ten-valent pneumococcal conjugate vaccine (PCV10) was introduced into the Chilean National Immunization Program (NIP) in January 2011 with a 3+1 schedule (2, 4, 6 and 12 months) without catch-up vaccination. We evaluated the effectiveness of PCV10 on pneumonia morbidity and mortality among infants during the first two years after vaccine introduction. Methods This is a population-based nested case-control study using four merged nationwide case-based electronic health data registries: live birth, vaccination, hospitalization and mortality. Children born in 2010 and 2011 were followed from two moths of age for a period of two years. Using four different case definitions of pneumonia hospitalization and/or mortality (all-cause and pneumonia related deaths), all cases and four randomly selected matched controls per case were selected. Controls were matched to cases on analysis time. Vaccination status was then assessed. Vaccine effectiveness (VE) was estimated using conditional logistic regression. Results There were a total of 497,996 children in the 2010 and 2011 Chilean live-birth cohorts. PCV10 VE was 11.2% (95%CI 8.5–13.6) when all pneumonia hospitalizations and deaths were used to define cases. VE increased to 20.7 (95%CI 17.3–23.8) when ICD10 codes used to denote viral pneumonia were excluded from the case definition. VE estimates on pneumonia deaths and all-cause deaths were 71.5 (95%CI 9.0–91.8) and 34.8 (95% CI 23.7–44.4), respectively. Conclusion PCV10 vaccination substantially reduced the number of hospitalizations due to pneumonia and deaths due to pneumonia and to all-causes over this study period. Our findings also reinforce the importance of having quality health information systems for measuring VE. PMID:27058873

    Full Text Available Summary Objective: several scores were developed in order to improve the determination of community acquired pneumonia (CAP severity and its management, mainly CURB-65 and SACP score. However, none of them were evaluated for risk assessment of in-hospital mortality, particularly in individuals who were non-immunosuppressed and/or without any comorbidity. In this regard, the present study was carried out. Methods: we performed a cross-sectional study in 272 immunocompetent patients without comorbidities and with a diagnosis of CAP. Performance of CURB- 65 and SCAP scores in predicting in-hospital mortality was evaluated. Also, variables related to death were assessed. Furthermore, in order to design a model of in-hospital mortality prediction, sampled individuals were randomly divided in two groups. The association of the variables with mortality was weighed and, by multiple binary regression, a model was constructed in one of the subgroups. Then, it was validated in the other subgroup. Results: both scores yielded a fair strength of agreement, and CURB-65 showed a better performance in predicting in-hospital mortality. In our casuistry, age, white blood cell counts, serum urea and diastolic blood pressure were related to death. The model constructed with these variables showed a good performance in predicting in-hospital mortality; moreover, only one patient with fatal outcome was not correctly classified in the group where the model was constructed and in the group where it was validated. Conclusion: our findings suggest that a simple model that uses only 4 variables, which are easily accessible and interpretable, can identify seriously ill patients with CAP

OBJETIVO: Determinar o impacto da multirresistência dos microorganismos na morbidade e mortalidade dos pacientes com pneumonia associada à ventilação mecânica. MÉTODO: Estudo de coorte retrospectivo. Em 40 meses consecutivos, 91 pacientes sob ventilação mecânica tiveram o diagnóstico de pneumonia. Os casos foram divididos entre causados por microorganismo multirresistente e causados por microorganismo sensível à antibioticoterapia. RESULTADOS: Pneumonia foi causada por microorganismo multirresistente em 75 casos (82,4% e por microorganismo sensível 16 (17,6% deles. As características clínicas e epidemiológicas não foram estatisticamente diferentes entre os grupos. O Staphylococcus aureus foi responsável por 27,5% dos episódios de pneumonia associada à ventilação mecânica e a Pseudomonas aeruginosa por 17,6%. A doença foi de início recente em 33 pacientes (36,3% e de início tardio em 58 deles (63,7%. Os tempos de ventilação mecânica, de internação em unidade de terapia intensiva e de internação hospitalar total não diferiram.

    Full Text Available Despite many reports documenting its epidemicity, little is known on the interaction of Acinetobacter baumannii with its host. To deepen our insight into this relationship, we studied persistence of and host response to different A. baumannii strains including representatives of the European (EU clones I-III in a mouse pneumonia model. Neutropenic mice were inoculated intratracheally with five A. baumannii strains and an A. junii strain and at several days morbidity, mortality, bacterial counts, airway inflammation, and chemo- and cytokine production in lungs and blood were determined. A. baumannii RUH875 and RUH134 (EU clone I and II, respectively and sporadic strain LUH8326 resulted in high morbidity/mortality, whereas A. baumannii LUH5875 (EU clone III, which is less widespread than clone I and II caused less symptoms. A. baumannii type strain RUH3023(T and A. junii LUH5851 did not cause disease. All strains, except A. baumannii RUH3023(T and A. junii LUH5851, survived and multiplied in the lungs for several days. Morbidity and mortality were associated with the severity of lung pathology and a specific immune response characterized by low levels of anti-inflammatory (IL-10 and specific pro-inflammatory (IL-12p40 and IL-23 cytokines at the first day of infection. Altogether, a striking difference in behaviour among the A. baumannii strains was observed with the clone I and II strains being most virulent, whereas the A. baumannii type strain, which is frequently used in virulence studies appeared harmless.

    Full Text Available To determine whether the pneumonia severity index (PSI can predict in-hospital mortality for AECOPD patients and compare its usefulness with the CURB65 and BAP65 indexes to predict mortality.Demographics, clinical signs and symptoms, comorbidities, and laboratory and radiographic findings of hospitalized AECOPD patients were obtained. Univariate and multiple logistic regression analyses were used to identify the risk factors for in-hospital mortality. The PSI, CURB65 and BAP65 scores were calculated. Receiver operating characteristic (ROC curve analysis was used to identify the PSI, CURB65 and BAP65 scores that could discriminate between non-survivors and survivors. To control for the confounding factor of invasive mechanical ventilation (IMV regarding the mortality of AECOPD, subgroup analysis was performed when excluded patients who had met the criteria of IMV but who had not received the cure of IMV according to their wishes.During the in-hospital period, 73 patients died and 679 patients recovered. Age, PaO2<60 mmHg, pH < 7.35, PaCO2≥50 mmHg, nursing home residency, congestive heart failure, liver disease, sodium<130 mmol/L, lower FEV1% and altered mental status were risk factors for in-hospital mortality. The areas under the ROC curves (AUCs of the PSI for death were 0.847 (95% CI: 0.799-0.895. The cut-off value was 116.5 with a sensitivity of 82.2% and a specificity of 77.6%. However, the AUCs of the CURB65 and BAP65 for death were only 0.744 (95% CI: 0.680-0.809 and 0.665 (95% CI: 0.594-0.736, respectively. Subgroup analysis also showed that the PSI score could predict the mortality of AECOPD patients with an AUC = 0.857 (95% CI: 0.802-0.913, with exclusion of the patients who met the criteria of IMV but who did not receive the cure of IMV.The PSI score may be used to predict in-hospital mortality for hospitalized AECOPD patients, with a prognostic capacity superior to CURB65 and BAP65.

    Globally, pneumonia is the leading cause of childhood mortality. Pneumonia is the second killer of children less than 5 years of age in China. The World Heath Organization and United Nations Children's Fund launched the integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhea (GAPPD) in 2013. The ambitious goal is to end preventable childhood deaths due to pneumonia by 2025. Countries or regions should achieve the following goals:(1) reduce mortality from pneumonia in children less than 5 years of age to fewer than 3 per 1 000 live births;(2) reduce the incidence of severe pneumonia by 75%in children less than 5 years of age compared to 2010 levels. If the implementation of key interventions is accelerated, the mortality rate of childhood pneumonia will drop substantially every year, which makes the goal achievable.%肺炎是全球儿童死亡的首位原因,也是我国5岁以下儿童死亡的第二位原因。世界卫生组织和联合国儿童基金会2013年发布了预防和控制肺炎和腹泻全球行动计划,提出了控制儿童肺炎的宏伟目标:2025年彻底避免儿童期肺炎可预防性死亡。在国家或地区层面上要实现:(1)5岁以下儿童肺炎死亡率低于3/1000活产儿;(2)与2010年比较,5岁以下严重肺炎的发生率下降75%。如能加快执行关键干预措施的步伐,儿童肺炎的死亡率会明显下降,目标就能实现。[中国当代儿科杂志,2014,16(10):967-969

    Full Text Available Background: Childhood mortality, particularly in the first 5 years of life, is a major global concern and the target of Millennium Development Goal 4. Although the majority of childhood deaths occur in Africa and Asia, these are also the regions where such deaths are least likely to be registered. The INDEPTH Network works to alleviate this problem by collating detailed individual data from defined Health and Demographic Surveillance sites. By registering deaths and carrying out verbal autopsies to determine cause of death across many such sites, using standardised methods, the Network seeks to generate population-based mortality statistics that are not otherwise available. Objective: To present a description of cause-specific mortality rates and fractions over the first 15 years of life as documented by INDEPTH Network sites in sub-Saharan Africa and south-east Asia. Design: All childhood deaths at INDEPTH sites are routinely registered and followed up with verbal autopsy (VA interviews. For this study, VA archives were transformed into the WHO 2012 VA standard format and processed using the InterVA-4 model to assign cause of death. Routine surveillance data also provided person-time denominators for mortality rates. Cause-specific mortality rates and cause-specific mortality fractions are presented according to WHO 2012 VA cause groups for neonatal, infant, 1–4 year and 5–14 year age groups. Results: A total of 28,751 childhood deaths were documented during 4,387,824 person-years over 18 sites. Infant mortality ranged from 11 to 78 per 1,000 live births, with under-5 mortality from 15 to 152 per 1,000 live births. Sites in Vietnam and Kenya accounted for the lowest and highest mortality rates reported. Conclusions: Many children continue to die from relatively preventable causes, particularly in areas with high rates of malaria and HIV/AIDS. Neonatal mortality persists at relatively high, and perhaps sometimes under-documented, rates

    The aim of this study was to evaluate the impact of PCV10 pneumococcal vaccine on mortality from pneumonia in children less than one year of age in Santa Catarina State, Brazil, comparing the four years prior and the four years subsequent to the vaccine's introduction in 2010. This ecological study used data from the Mortality Information System and vaccination coverage of children less than one year. Data were grouped by municipalities of residence and regions. Average mortality from pneumonia in children under one year decreased from 29.69 to 23.40 per 100,000, comparing 2006-2009 and 2010-2013, or a reduction of 11%. However there were differences between regions with a drop in mortality (Grande Florianópolis, Sul, Planalto Norte, and Nordeste) and others with an increase in the annual rates (Oeste, Itajaí, and Serra). In short, the state as a whole showed 11% reduction in mortality from pneumonia in children less than one year of age, four years after implementing routine PCV10 vaccination in the National Immunization Program, but with heterogeneous effects when comparing regions of the state.

    The prevalence of extended-spectrum beta-lactamase (ESBL)-positive Klebsiella pneumoniae is growing worldwide. Infections with these bacteria are suspected to be related to increased mortality. We aimed to estimate the distribution of ESBL genotypes and to assess the impact on mortality associated with ESBL positivity in cases of bloodstream infection (BSI) due to K. pneumoniae. We performed a cohort study on patients with K. pneumoniae BSI between 2008 and 2011. Presence of ESBL genes was analyzed by PCR and sequencing. Risk factors for mortality were analyzed by Cox-proportional hazard regression. We identified 286 ESBL-negative (81%) and 66 (19%) ESBL-positive cases. 97% (n = 64) of the ESBL-positive isolates were susceptible for meropenem. The most common ESBL genotypes were CTX-M-15 (60%), SHV-5 (27%) and CTX-M-3 (5%). Significant risk factors for mortality were chronic pulmonary disease (HR 1.747) and moderate/severe renal disease (HR 2.572). ESBL positivity was not associated with increased mortality.

    Severe malarial anemia (SMA) is a leading cause of morbidity and mortality in children residing in regions where Plasmodium falciparum transmission is holoendemic. Although largely unexplored in children with SMA, interleukin-18 (IL-18) is important for regulating innate and acquired immunity in inflammatory and infectious diseases. As such, we selected two functional single-nucleotide polymorphisms (SNPs) in the IL-18 promoter (-137G→C [rs187238] and -607C→A [rs1946518]) whose haplotypes encompass significant genetic variation due to the presence of strong linkage disequilibrium among these variants. The relationship between the genotypes/haplotypes, SMA (hemoglobin [Hb], sickle cell trait, glucose-6-phosphate dehydrogenase (G6PD) deficiency, HIV-1, and bacteremia revealed that carriage of the -607AA genotype was associated with protection against SMA (odds ratio [OR] = 0.440 [95% confidence interval {CI} = 0.21 to 0.90], P = 0.031) in children with acute infection. In contrast, carriers of the -137G/-607C (GC) haplotype had increased susceptibility to SMA (OR = 2.050 [95% CI = 1.04 to 4.05], P = 0.039). Measurement of IL-18 gene expression in peripheral blood leukocytes demonstrated that elevated IL-18 transcripts were associated with reduced hemoglobin concentrations (ρ = -0.293, P = 0.010) and that carriers of the "susceptible" GC haplotype had elevated IL-18 transcripts (P = 0.026). Longitudinal investigation of clinical outcomes over a 3-year follow-up period revealed that carriers of the rare CC haplotype (∼1% frequency) had 5.76 times higher mortality than noncarriers (P = 0.001). Results presented here demonstrate that IL-18 promoter haplotypes that condition elevated IL-18 gene products during acute infection are associated with increased risk of SMA. Furthermore, carriage of the rare CC haplotype significantly increases the risk of childhood mortality.

    Full Text Available Background: Ventilator-associated pneumonia (VAP is the most common nosocomial infection diagnosed in the intensive care unit (ICU and in spite of advances in diagnostic techniques and management it remains a common cause of hospital morbidity and mortality. Objective: The primary objective of the following study is to determine the incidence, various risk factors and attributable mortality associated with VAP and secondary objective is to identify the various bacterial pathogens causing VAP in the ICU. Materials and Methods: This prospective observational study was carried out over a period of 1 year. VAP was diagnosed using the clinical pulmonary infection score. Endotracheal aspirate (ETA and bronchoalveolar lavage (BAL samples of suspected cases of VAP were collected from ICU patients and processed as per standard protocols. Statistical Analysis: Fisher′s exact test was applied when to compare two or more set of variables were compared. Results: The incidence of VAP in our study was 57.14% and the incidence density of VAP was 31.7/1000 ventilator days. Trauma was the commonest underlying condition associated with VAP. The incidence of VAP increased as the duration of mechanical ventilation increased and there was a total agreement in bacteriology between semi-quantitative ETAs and BALs in our study. The overall mortality associated with VAP was observed to be 48.33%. Conclusions: The incidence of VAP was 57.14%. Study showed that the incidence of VAP is directly proportional to the duration of mechanical ventilation. The most common pathogens causing VAP were Acinetobacter spp. and Pseudomonas aeruginosa and were associated with a high fatality rate.

    Full Text Available BACKGROUND: Pneumonia, diarrhea and measles are the leading causes of death in children worldwide, but have a disproportionately low share of international funding and media attention. In comparison, AIDS, tuberculosis and malaria--diseases that also significantly affect children--receive considerably more funding and have relatively high media coverage. This study investigates the potential relationship between media agenda setting and funding levels in the context of the actual burden of disease. METHODS: The news databases Lexis Nexis, Factiva, and Google News Archive were searched for the diseases AIDS, TB and Malaria and for lower funded pediatric diseases: childhood pneumonia, diarrhea, and measles. A sample of news articles across geographic regions was also analyzed using a qualitative narrative frame analysis of how the media stories were told. RESULTS: There were significantly more articles addressing the Global Fund diseases compared to the lower funded pediatric diseases between 1981 and 2008 (1,344,150 versus 291,865 articles. There were also notable differences in the framing of media narratives: 1 There was a high proportion of articles with the primary purpose of raising awareness for AIDS, TB and malaria (46.2% compared with only 17.9% of the pediatric disease articles. 2 Nearly two-thirds (61.5% of the AIDS, tuberculosis and malaria articles used a human rights, legal or social justice frame, compared with 46.2% for the lower funded pediatric disease articles, which primarily used an ethical or moral frame. CONCLUSION: This study demonstrates that lower funded pediatric diseases are presented differently in the media, both quantitatively and qualitatively, than higher funded, higher profile diseases.

  12. Estimating oxygen needs for childhood pneumonia in developing country health systems: a new model for expecting the unexpected.

    Directory of Open Access Journals (Sweden)

    Beverly D Bradley

    Full Text Available BACKGROUND: Planning for the reliable and cost-effective supply of a health service commodity such as medical oxygen requires an understanding of the dynamic need or 'demand' for the commodity over time. In developing country health systems, however, collecting longitudinal clinical data for forecasting purposes is very difficult. Furthermore, approaches to estimating demand for supplies based on annual averages can underestimate demand some of the time by missing temporal variability. METHODS: A discrete event simulation model was developed to estimate variable demand for a health service commodity using the important example of medical oxygen for childhood pneumonia. The model is based on five key factors affecting oxygen demand: annual pneumonia admission rate, hypoxaemia prevalence, degree of seasonality, treatment duration, and oxygen flow rate. These parameters were varied over a wide range of values to generate simulation results for different settings. Total oxygen volume, peak patient load, and hours spent above average-based demand estimates were computed for both low and high seasons. FINDINGS: Oxygen demand estimates based on annual average values of demand factors can often severely underestimate actual demand. For scenarios with high hypoxaemia prevalence and degree of seasonality, demand can exceed average levels up to 68% of the time. Even for typical scenarios, demand may exceed three times the average level for several hours per day. Peak patient load is sensitive to hypoxaemia prevalence, whereas time spent at such peak loads is strongly influenced by degree of seasonality. CONCLUSION: A theoretical study is presented whereby a simulation approach to estimating oxygen demand is used to better capture temporal variability compared to standard average-based approaches. This approach provides better grounds for health service planning, including decision-making around technologies for oxygen delivery. Beyond oxygen, this approach

    Community acquired pneumonia (CAP) is a common reason for hospitalization and death in elderly people. Many predictors of in-hospital outcome have been studied in the general population with CAP. However, data are lacking on the prognostic significance of conditions unique to older patients, such as delirium and the coexistence of multiple comorbidities. The aim of this study was to evaluate predictors of in-hospital outcome in elderly patients hospitalized for CAP. In this retrospective study, consecutive patients with CAP aged ≥65 years were enrolled between January 2011 and June 2012 in two general wards. Clinical and laboratory characteristics were collected from electronic medical records. The end-point of the study was the occurrence of in-hospital death. 443 patients (mean age 81.8 ± 7.5, range 65-99 years) were enrolled. More than 3 comorbidities were present in 31 % of patients. Mean confusion, blood urea nitrogen, respiratory rate, blood pressure and age ≥65 years (CURB-65) score was 2.5 ± 0.7 points. Mean length of stay was 7.6 ± 5.7 days. In-hospital death occurred in 54 patients (12.2 %). At multivariate analysis, independent predictors of in-hospital death were: chronic obstructive pulmonary disease (COPD) (OR 6.21, p = 0.005), occurrence of at least one episode of delirium (OR 5.69, p = 0.017), male sex (OR 5.10, p patients with CAP older than 65 years are similar to those of younger patients. In this cohort of elderly patients, the occurrence of delirium was highly prevalent and represented a distinctive predictor of death.

    Full Text Available Clinical isolates of Klebsiella pneumoniae are divided into three phylogroups and differ in their virulence factor contents. The aim of this study was to determine an association between phylogroup, virulence factors and mortality following bloodstream infection (BSI caused by Klebsiella pneumoniae. Isolates from all adult patients with BSI caused by K. pneumoniae admitted to Karolinska University Hospital, Solna between 2007 and 2009 (n = 139 were included in the study. Phylogenetic analysis was performed based on multilocus sequence typing (MLST data. Testing for mucoid phenotype, multiplex PCR determining serotypes K1, K2, K5, K20, K54 and K57, and testing for virulence factors connected to more severe disease in previous studies, was also performed. Data was retrieved from medical records including age, sex, comorbidity, central and urinary catheters, time to adequate treatment, hospital-acquired infection, and mortality, to identify risk factors. The primary end-point was 30- day mortality. The three K. pneumoniae phylogroups were represented: KpI (n = 96, KpII (corresponding to K. quasipneumoniae, n = 9 and KpIII (corresponding to K. variicola, n = 34.

    An unusual mortality event (UME) involving primarily common bottlenose dolphins Tursiops truncatus of all size classes stranding along coastal Louisiana, Mississippi, and Alabama, USA, started in early 2010 and continued into 2014. During this northern Gulf of Mexico UME, a distinct cluster of perinatal dolphins (total body length <115 cm) stranded in Mississippi and Alabama during 2011. The proportion of annual dolphin strandings that were perinates between 2009 and 2013 were compared to baseline strandings (2000-2005). A case-reference study was conducted to compare demographics, histologic lesions, and Brucella sp. infection prevalence in 69 UME perinatal dolphins to findings from 26 reference perinates stranded in South Carolina and Florida outside of the UME area. Compared to reference perinates, UME perinates were more likely to have died in utero or very soon after birth (presence of atelectasis in 88 vs. 15%, p < 0.0001), have fetal distress (87 vs. 27%, p < 0.0001), and have pneumonia not associated with lungworm infection (65 vs. 19%, p = 0.0001). The percentage of perinates with Brucella sp. infections identified via lung PCR was higher among UME perinates stranding in Mississippi and Alabama compared to reference perinates (61 vs. 24%, p = 0.01), and multiple different Brucella omp genetic sequences were identified in UME perinates. These results support that from 2011 to 2013, during the northern Gulf of Mexico UME, bottlenose dolphins were particularly susceptible to late-term pregnancy failures and development of in utero infections including brucellosis.

    Full Text Available The Cooking and Pneumonia Study (CAPS is a pragmatic cluster-level randomized controlled trial of the effect of an advanced cookstove intervention on pneumonia in children under the age of 5 years (under 5s in Malawi (www.capstudy.org. The primary outcome of the trial is the incidence of pneumonia during a two-year follow-up period, as diagnosed by healthcare providers who are using the World Health Organization (WHO integrated management of childhood illnesses (IMCI pneumonia assessment protocol and who are blinded to the trial arms. We evaluated the quality of pneumonia assessment in under 5s in this setting via a cross-sectional study of provider-patient encounters at nine outpatient clinics located within the catchment area of 150 village-level clusters enrolled in the trial across the two study locations of Chikhwawa and Karonga, Malawi, between May and June 2015 using the IMCI guidelines as a benchmark. Data were collected using a key equipment checklist, an IMCI pneumonia knowledge test, and a clinical evaluation checklist. The median number of key equipment items available was 6 (range 4 to 7 out of a possible 7. The median score on the IMCI pneumonia knowledge test among 23 clinicians was 75% (range 60% to 89%. Among a total of 176 consultations performed by 15 clinicians, a median of 9 (range 3 to 13 out of 13 clinical evaluation tasks were performed. Overall, the clinicians were adequately equipped for the assessment of sick children, had good knowledge of the IMCI guidelines, and conducted largely thorough clinical evaluations. We recommend the simple pragmatic approach to quality assurance described herein for similar studies conducted in challenging research settings.

    Despite the rapid growth of social franchising, there is little evidence on its population impact in the health sector. Similar in many ways to private-sector commercial franchising, social franchising can be found in sectors with a social objective, such as health care. This article evaluates the World Health Partners (WHP) Sky program, a large-scale social franchising and telemedicine program in Bihar, India. We studied appropriate treatment for childhood diarrhea and pneumonia and associated health care outcomes. We used multivariate difference-in-differences models to analyze data on 67,950 children ages five and under in 2011 and 2014. We found that the WHP-Sky program did not improve rates of appropriate treatment or disease prevalence. Both provider participation and service use among target populations were low. Our results do not imply that social franchising cannot succeed; instead, they underscore the importance of understanding factors that explain variation in the performance of social franchises. Our findings also highlight, for donors and governments in particular, the importance of conducting rigorous impact evaluations of new and potentially innovative health care delivery programs before investing in scaling them up.

    The contribution of specific cancer therapies, comorbid medical conditions, and host factors to mortality risk after pediatric Hodgkin lymphoma (HL) is unclear. We assessed leading morbidities, overall and cause-specific mortality, and mortality risks among 2742 survivors of HL in the Childhood Cancer Survivor Study, a multi-institutional retrospective cohort study of survivors diagnosed from 1970 to 1986. Excess absolute risk for leading causes of death and cumulative incidence and standardized incidence ratios of key medical morbidities were calculated. Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of risks for overall and cause-specific mortality. Substantial excess absolute risk of mortality per 10,000 person-years was identified: overall 95.5; death due to HL 38.3, second malignant neoplasms 23.9, and cardiovascular disease 13.1. Risks for overall mortality included radiation dose ≥ 3000 rad ( ≥ 30 Gy; supra-diaphragm: HR, 3.8; 95% CI, 1.1-12.6; infradiaphragm + supradiaphragm: HR, 7.8; 95% CI, 2.4-25.1), exposure to anthracycline (HR, 2.6; 95% CI, 1.6-4.3) or alkylating agents (HR, 1.7; 95% CI, 1.2-2.5), non-breast second malignant neoplasm (HR, 2.6; 95% CI 1.4-5.1), or a serious cardiovascular condition (HR, 4.4; 95% CI 2.7-7.3). Excess mortality from second neoplasms and cardiovascular disease vary by sex and persist > 20 years of follow-up in childhood HL survivors.

    A prospective observational study of 226 intensive care unit (ICU) patients was conducted during a 25-month period. Rectal samples were taken at day 1, 4, and 7 and, afterwards, once weekly. Klebsiella pneumoniae was identified using standard techniques, whereas the presence of bla(KPC) gene was confirmed by PCR. During ICU stay, 72.6% of the patients were colonized with Klebsiella pneumoniae carbapenemases (KPC)-producing K. pneumoniae (KPC-Kp). Male gender, prior bed occupants, and patients in nearby beds colonized with KPC-Kp, tracheotomy, number of invasive catheters inserted, and number of antibiotics administered were the major risk factors for KPC-Kp colonization. ICU mortality (35.4%) was significantly related to Simplified Acute Physiology II score and respiratory insufficiency upon admission, cortisone administration, aminoglycoside administration, confirmed KPC-Kp infection, and severe sepsis or septic shock. The high prevalence of KPC-Kp enteric carriage in ICU patients and the significant mortality associated with KPC-Kp infection dictate the importance of early identification and isolation of such carriers.

All the enrolled children were treated with ampicillin and gentamicin, and micronutrients as recommended by the WHO. Comparison was made among pneumonic children with (n = 111 and without WHO defined danger signs of severe pneumonia (n = 296. The outcomes of interest were treatment failure (if a child required changing of antibiotics and deaths during hospitalization. Further comparison was also made among those who developed treatment failure and who did not and among the survivors and deaths.SAM children with danger signs of severe pneumonia more often experienced treatment failure (58% vs. 20%; p<0.001 and fatal outcome (21% vs. 4%; p<0.001 compared to those without danger signs.

    Full Text Available Background: Major improvements are required in the coverage and quality of essential childhood interventions to achieve Millennium Development Goal Four (MDG 4. Long distance to health facilities is one of the known barriers to access. We investigated the effect of networked and Euclidean distances from home to formal health facilities on childhood mortality in rural Tanzania between 2005 and 2007. Methods: A secondary analysis of data from a cohort of 28,823 children younger than age 5 between 2005 and 2007 from Ifakara Health and Demographic Surveillance System was carried out. Both Euclidean and networked distances from the household to the nearest health facility were calculated using geographical information system methods. Cox proportional hazard regression models were used to investigate the effect of distance from home to the nearest health facility on child mortality. Results: Children who lived in homes with networked distance >5 km experienced approximately 17% increased mortality risk (HR=1.17; 95% CI 1.02–1.38 compared to those who lived <5 km networked distance to the nearest health facility. Death of a mother (HR=5.87; 95% CI 4.11–8.40, death of preceding sibling (HR=1.9; 95% CI 1.37–2.65, and twin birth (HR=2.9; 95% CI 2.27–3.74 were the strongest independent predictors of child mortality. Conclusions: Physical access to health facilities is a determinant of child mortality in rural Tanzania. Innovations to improve access to health facilities coupled with birth spacing and care at birth are needed to reduce child deaths in rural Tanzania.

    Full Text Available Contributors to long-term mortality in patients with community-acquired pneumonia (CAP remain unclear, with little attention paid to pneumonia etiology. We examined long-term survival, causes of death, and risk factors for long-term mortality in adult patients who had been hospitalized for CAP, with emphasis on demographic, clinical, laboratory, and microbiological characteristics.Two hundred and sixty-seven consecutive patients admitted in 2008-2011 to a general hospital with CAP were prospectively recruited and followed up. Patients who died during hospital stay were excluded. Demographic, clinical, and laboratory data were collected within 48 hours of admission. Extensive microbiological work-up was performed to establish the etiology of CAP in 63% of patients. Mortality data were obtained from the Norwegian Cause of Death Registry. Cox regression models were used to identify independent risk factors for all-cause mortality.Of 259 hospital survivors of CAP (median age 66 years, 79 (30.5% died over a median of 1,804 days (range 1-2,520 days. Cumulative 5-year survival rate was 72.9% (95% CI 67.4-78.4%. Standardized mortality ratio was 2.90 for men and 2.05 for women. The main causes of death were chronic obstructive pulmonary disease (COPD, vascular diseases, and malignancy. Independent risk factors for death were the following (hazard ratio, 95% CI: age (1.83 per decade, 1.47-2.28, cardiovascular disease (2.63, 1.61-4.32, COPD (2.09, 1.27-3.45, immunocompromization (1.98, 1.17-3.37, and low serum albumin level at admission (0.75 per 5 g/L higher, 0.58-0.96, whereas active smoking was protective (0.32, 0.14-0.74; active smokers were younger than non-smokers (P < 0.001. Microbial etiology did not predict mortality.Results largely confirm substantial comorbidity-related 5-year mortality after hospitalization for CAP and the impact of several well-known risk factors for death, and extend previous findings on the prognostic value of serum albumin

    This article documents the levels and patterns of infant and child mortality among Palestinian refugees in Jordan, Lebanon and the Palestinian areas based on comparable data from household sample surveys conducted since 1995. The findings show that Palestinian refugees have clear advantage in mortality levels as compared to their non-refugee counterparts in every setting, and refugees living in the camps have similar or lower levels of mortality than their non-camp counterparts, other things being equal. The recent decline of infant and child mortality among this vulnerable segment of the Palestinian population demonstrates the importance of political will in halting the truncation of infant lives. An examination of the mortality patterns by sex and education sheds light on the nature of the decline currently underway.

    Several studies examining the incidence of viral infection in childhood community-acquired pneumonia (CAP) utilizing polymerase chain reaction (PCR) or real-time PCR methods have been reported. We systematically searched Pubmed and Embase for studies reporting the incidence of respiratory viral infection in childhood CAP. The pooled incidences of viral infection were calculated with a random-effects model. Sources of heterogeneity were explored by subgroup analysis and a univariant metaregression analysis. We included 21 eligible reports in our study. We found significant heterogeneity on the incidence of viral infection in childhood CAP. The random effects pooled incidence was 57.4% (95% confidence interval (CI): 50.8-64.1). The pooled incidence of mixed infection was 29.3% (95%CI: 23.0-35.6) with considerable heterogeneity. The pooled incidence of mixed infection was 29.3% (95%CI: 23.0-35.6). Rhinovirus, respiratory syncytial virus (RSV) and bocavirus were found to be the three most common viruses in childhood CAP. We also demonstrated that respiratory viruses were detected in 76.1% of patients aged ≤ 1 year, 63.1% of patients aged 2-5 years and 27.9% of patients aged ≥ 6 years. We conclude that respiratory viruses are widely detected in paediatric patients with CAP by PCR or real-time PCR methods. More than half of viral infections are probably concurrent with bacterial infections. Rhinovirus, RSV and bocavirus are the three most frequent viruses identified in childhood CAP; the incidence of viral infection decreased with age.

    Full Text Available Low birthweight (LBW is associated with increased mortality in infancy, but its association with mortality in later childhood and adolescence is less clear. We investigated the association between birthweight and all-cause mortality and identified major causes of mortality for different birthweight groups.We conducted a population study of all live births occurring in England and Wales between 1 January 1993 and 31 December 2011. Following exclusions, the 12,355,251 live births were classified by birthweight: 500-1,499 g (very LBW [VLBW], n = 139,608, 1,500-2,499 g (LBW, n = 759,283, 2,500-3,499 g (n = 6,511,411, and ≥3,500 g (n = 4,944,949. The association of birthweight group with mortality in infancy (<1 y of age and childhood/adolescence (1-18 y of age was quantified, with and without covariates, through hazard ratios using Cox regression. International Classification of Diseases codes identified causes of death. In all, 74,890 (0.61% individuals died between birth and 18 y of age, with 23% of deaths occurring after infancy. Adjusted hazard ratios for infant deaths were 145 (95% CI 141, 149 and 9.8 (95% CI 9.5, 10.1 for the VLBW and LBW groups, respectively, compared to the ≥3,500 g group. The respective hazard ratios for death occurring at age 1-18 y were 6.6 (95% CI 6.1, 7.1 and 2.9 (95% CI 2.8, 3.1. Male gender, the youngest and oldest maternal age bands, multiple births, and deprivation (Index of Multiple Deprivation score also contributed to increased deaths in the VLBW and LBW groups in both age ranges. In infancy, perinatal factors, particularly respiratory issues and infections, explained 84% and 31% of deaths in the VLBW and LBW groups, respectively; congenital malformations explained 36% and 23% in the LBW group and ≥2,500 g groups (2,500-3,499 g and ≥3,500 g groups combined, respectively. Central nervous system conditions explained 20% of deaths in childhood/adolescence in the VLBW group, with deaths from neoplasms and

    Full Text Available OBJECTIVE: Leukemias comprise the most common group of cancers in children and adolescents. Studies conducted in other countries and Brazil have observed a decrease in their mortality.This study aimed to evaluate the trend of mortality from leukemia in children under 19 years of age in Brazil, from 1980 to 2010. METHODS: This was an ecological study, using retrospective time series data from the Mortality Information System, from 1980 to 2010. Calculations of mortality rates were performed, including gross, gender-specific, and age-based. For trend analysis, linear and semi-log regression models were used. The significance level was 5%. RESULTS: Mortality rates for lymphoid and myeloid leukemias presented a growth trend, with the exception of lymphoid leukemia among children under 4 years of age (percentage decrease: 1.21% annually, while in the sub-group "Other types of leukemia", a downward trend was observed. Overall, mortality from leukemia tended to increase for boys and girls, especially in the age groups 10-14 years (annual percentage increase of 1.23% for males and 1.28% for females and 15-19 years (annual percentage increase of 1.40% for males and 1.62% for females. CONCLUSIONS: The results for leukemia generally corroborate the results of other similar studies. A detailed analysis by subgroup of leukemia, age, and gender revealed no trends shown in other studies, thus indicating special requirements for each variable in the analysis.

  13. Estimating pneumonia deaths of post-neonatal children in countries of low or no death certification in 2008.

    Directory of Open Access Journals (Sweden)

    Evropi Theodoratou

    Full Text Available BACKGROUND: Pneumonia is the leading cause of child deaths globally. The aims of this study were to: a estimate the number and global distribution of pneumonia deaths for children 1-59 months for 2008 for countries with low (85% coverage of death certification countries was used. For 87 high child-mortality countries pneumonia death estimates were obtained by applying a regression model developed from published and unpublished verbal autopsy data from high child-mortality settings. The total number of 1-59 months pneumonia deaths for the year 2008 for these 122 countries was estimated to be 1.18 M (95% CI 0.77 M-1.80 M, which represented 23.27% (95% CI 17.15%-32.75% of all 1-59 month child deaths. The country level estimation correlation coefficient between these two methods was 0.40. INTERPRETATION: Although the overall number of post-neonatal pneumonia deaths was similar irrespective to the method of estimation used, the country estimate correlation coefficient was low, and therefore country-specific estimates should be interpreted with caution. Pneumonia remains the leading cause of child deaths and is greatest in regions of poverty and high child-mortality. Despite the concerns about gender inequity linked with childhood mortality we could not estimate sex-specific pneumonia mortality rates due to the inadequate data. Life-saving interventions effective in preventing and treating pneumonia mortality exist but few children in high pneumonia disease burden regions are able to access them. To achieve the United Nations Millennium Development Goal 4 target to reduce child deaths by two-thirds in year 2015 will require the scale-up of access to these effective pneumonia interventions.

    Imperfect technology and lack of management and utilization facilities for reprocessing liquid waste released by the Mayak PA resulted in a protracted combined (external and internal) environmental radiation exposure of the population resident on the banks of the Techa River. The followup of 8.640 subjects exposed during the prenatal period and in childhood covered the period of 49 years (1.1.1950-31.12.1998), the total person-years under observation amounted to 222,686. From 1950 through 1998 1,231 death cases were registered in the catchment area (5 raions in Chelyabinsk OBlast through which the Techa flows). In 70 cases death was caused by solid cancers, and in 12 cases by leukemia. Analyses of solid cancer mortality yielded higher rates for men as compared to women (p<0.001). No significant differences in death rates were observed between different ethnic groups (Slavs vs Tartars and Bashkirs). A statistically significant increase in solid cancer mortality with attained age was shown (p<0.001). The age at first exposure was demonstrated to be a factor modifying the solid cancer mortality rate (p=0.049). The highest risk of death from solid cancers was manifested by persons whose exposure started in the prenatal period or at the age under 5 years. There were 4.6 excess cases in this group of 30 observed solid cancer cases, whereas in the group including subjects aged 5 years or older at first exposure only 1 excess case was registered among the 40 observed cancer cases. The obtained leukemia mortality ERR value (CLL excluded) was 7.76, p=0.09. The excess leukemia death was found to be 7.6 out of of 10 observed cases. The analysis performed should be regarded as a preliminary one, taking into account the need to further extend the followup of the cohort and a potential verification of dose estimates in the future.

    Objectives To evaluate the effects on non-specific and all cause mortality, in children under 5, of Bacillus Calmette-Guérin (BCG), diphtheria-tetanus-pertussis (DTP), and standard titre measles containing vaccines (MCV); to examine internal validity of the studies; and to examine any modifying effects of sex, age, vaccine sequence, and co-administration of vitamin A. Design Systematic review, including assessment of risk of bias, and meta-analyses of similar studies. Study eligibility criteria Clinical trials, cohort studies, and case-control studies of the effects on mortality of BCG, whole cell DTP, and standard titre MCV in children under 5. Data sources Searches of Medline, Embase, Global Index Medicus, and the WHO International Clinical Trials Registry Platform, supplemented by contact with experts in the field. To avoid overlap in children studied across the included articles, findings from non-overlapping birth cohorts were identified. Results Results from 34 birth cohorts were identified. Most evidence was from observational studies, with some from short term clinical trials. Most studies reported on all cause (rather than non-specific) mortality. Receipt of BCG vaccine was associated with a reduction in all cause mortality: the average relative risks were 0.70 (95% confidence interval 0.49 to 1.01) from five clinical trials and 0.47 (0.32 to 0.69) from nine observational studies at high risk of bias. Receipt of DTP (almost always with oral polio vaccine) was associated with a possible increase in all cause mortality on average (relative risk 1.38, 0.92 to 2.08) from 10 studies at high risk of bias; this effect seemed stronger in girls than in boys. Receipt of standard titre MCV was associated with a reduction in all cause mortality (relative risks 0.74 (0.51 to 1.07) from four clinical trials and 0.51 (0.42 to 0.63) from 18 observational studies at high risk of bias); this effect seemed stronger in girls than in boys.

  20. Why are women so intelligent? The effect of maternal IQ on childhood mortality may be a relevant evolutionary factor.

    Science.gov (United States)

    Charlton, Bruce G

    2010-03-01

    Humans are an unusual species because they exhibit an economic division of labour. Most theories concerning the evolution of specifically human intelligence have focused either on economic problems or sexual selection mechanisms, both of which apply more to men than women. Yet while there is evidence for men having a slightly higher average IQ, the sexual dimorphism of intelligence is not obvious (except at unusually high and low levels). However, a more female-specific selection mechanism concerns the distinctive maternal role in child care during the offspring's early years. It has been reported that increasing maternal intelligence is associated with reducing child mortality. This would lead to a greater level of reproductive success for intelligent women, and since intelligence is substantially heritable, this is a plausible mechanism by which natural selection might tend to increase female intelligence in humans. Any effect of maternal intelligence on improving child survival would likely be amplified by assortative mating for IQ by which people tend to marry others of similar intelligence - combining female maternal and male economic or sexual selection factors. Furthermore, since general intelligence seems to have the functional attribute of general purpose problem-solving and more rapid learning, the advantages of maternal IQ are likely to be greater as the environment for child-rearing is more different from the African hunter-gatherer society and savannah environment in which ancestral humans probably evolved. However, the effect of maternal IQ on child mortality would probably only be of major evolutionary significance in environments where childhood mortality rates were high. The modern situation is that population growth is determined mostly by birth rates; so in modern conditions, maternal intelligence may no longer have a significant effect on reproductive success; the effect of female IQ on reproductive success is often negative. Nonetheless, in the

    Full Text Available We aimed to evaluate sociodemographic, epidemiological, and clinical risk factors for pulmonary tuberculosis (PTB in children presenting with severe acute malnutrition (SAM and pneumonia. Children aged 0 to 59 months with SAM and radiologic pneumonia from April 2011 to July 2012 were studied in Bangladesh. Children with confirmed PTB (by culture and/or X-pert MTB/RIF (cases = 27 and without PTB (controls = 81; randomly selected from 378 children were compared. The cases more often had the history of contact with active PTB patient (P < .01 and exposure to cigarette smoke (P = .04 compared with the controls. In logistic regression analysis, after adjusting for potential confounders, the cases were independently associated with working mother (P = .05 and positive tuberculin skin test (TST; P = .02. Thus, pneumonia in SAM children is a common presentation of PTB and further highlights the importance of the use of simple TST and/or history of contact with active TB patients in diagnosing PTB in such children, especially in resource-limited settings.

    Introduction Measurement of mortality in patients with acute myocardial infarction (AMI), congestive heart failure (CHF) and pneumonia (PN) is a high priority since these are common reasons for hospitalization. However, mortality in patients with inflammatory bowel disease (IBD) that are hospitalized for these common medical conditions is unknown. Methods A retrospective review of the 2005–2011 National Inpatient Sample (NIS), (approximately a 20% sample of discharges from community hospitals) was performed. A dataset for all patients with ICD-9-CM codes for primary diagnosis of acute myocardial infarction, pneumonia or congestive heart failure with a co-diagnosis of IBD, Crohn’s disease (CD) or ulcerative colitis (UC). 1:3 propensity score matching between patients with co-diagnosed disease vs. controls was performed. Continuous variables were compared between IBD and controls. Categorical variables were reported as frequency (percentage) and analyzed by Chi-square tests or Fisher’s exact test for co-diagnosed disease vs. control comparisons. Propensity scores were computed through multivariable logistic regression accounting for demographic and hospital factors. In-hospital mortality between the groups was compared. Results Patients with IBD, CD and UC had improved survival after AMI compared to controls. 94/2280 (4.1%) of patients with IBD and AMI died, compared to 251/5460 (5.5%) of controls, p = 0.01. This represents a 25% improved survival in IBD patients that were hospitalized with AMI. There was a 34% improved survival in patients with CD and AMI. There was a trend toward worsening survival in patients with IBD and CHF. Patients with CD and PN had improved survival compared to controls. 87/3362 (2.59%) patients with CD and PN died, compared to 428/10076 (4.25%) of controls, p < .0001. This represents a 39% improved survival in patients with CD that are hospitalized for PN. Conclusion IBD confers a survival benefit for patients hospitalized with AMI. A

    Full Text Available Zinc is an essential nutrient particularly important for growing children and for those who experience frequent infections. Many children in developing countries have inadequate zinc nutrition that impairs their immune system. Diarrhea and pneumonia are among the leading causes of morbidity and mortality in children of low-income countries. Zinc deficiency increases the susceptibility to these infections and administration of zinc to children with diarrhea and, possibly, pneumonia speeds up recovery. Furthermore, zinc given to otherwise healthy children also reduces the incidence of diarrhea and pneumonia. Thus, thousands of lives can be saved every year by giving zinc to prevent childhood infections or by providing zinc to children with ongoing infections. This paper gives a brief outline of the history of zinc research and reviews existing evidence from clinical trials on the prophylactic and therapeutic effect of oral zinc on childhood pneumonia and diarrhea

    Immunosuppression after measles is known to predispose people to opportunistic infections for a period of several weeks to months. Using population-level data, we show that measles has a more prolonged effect on host resistance, extending over 2 to 3 years. We find that nonmeasles infectious disease mortality in high-income countries is tightly coupled to measles incidence at this lag, in both the pre- and post-vaccine eras. We conclude that long-term immunologic sequelae of measles drive interannual fluctuations in nonmeasles deaths. This is consistent with recent experimental work that attributes the immunosuppressive effects of measles to depletion of B and T lymphocytes. Our data provide an explanation for the long-term benefits of measles vaccination in preventing all-cause infectious disease. By preventing measles-associated immune memory loss, vaccination protects polymicrobial herd immunity.

    Full Text Available Abstract Background Millions of children die every year in developing countries, from preventable diseases such as pneumonia and diarrhoea, owing to low levels of investment in child health. Investment efforts are hampered by a general lack of adequate information that is necessary for priority setting in this sector. This paper measures the health system costs of providing inpatient and outpatient services, and also the costs associated with treating pneumonia and diarrhoea in under-five children at a health centre in Zambia. Methods Annual economic and financial cost data were collected in 2005-2006. Data were summarized in a Microsoft excel spreadsheet to obtain total department costs and average disease treatment costs. Results The total annual cost of operating the health centre was US$1,731,661 of which US$1 284 306 and US$447,355 were patient care and overhead departments costs, respectively. The average cost of providing out-patient services was US$3 per visit, while the cost of in-patient treatment was US$18 per bed day. The cost of providing dental services was highest at US$20 per visit, and the cost of VCT services was lowest, with US$1 per visit. The cost per out-patient visit for under-five pneumonia was US$48, while the cost per bed day was US$215. The cost per outpatient visit attributed to under-five diarrhoea was US$26, and the cost per bed day was US$78. Conclusion In the face of insufficient data, a cost analysis exercise is a difficult but feasible undertaking. The study findings are useful and applicable in similar settings, and can be used in cost effectiveness analyses of health interventions.

    Physiological disruptions resulting from an impoverished environment during the first years of life are of key importance for the health and biological status of individuals and populations. Studies of growth processes in archaeological populations point to the fact that the main causes of childhood mortality in the past are to be sought among extrinsic factors. Based on this assumption, one would expect random mortality of children, with the deceased individuals representing the entire subadult population. The purpose of this study is to explore whether differences in early childhood survival are reflected in differences in deciduous tooth enamel, which can provide an insight into the development of an individual during prenatal and perinatal ontogeny. Deciduous incisors were taken from 83 individuals aged 2.0-6.5 years from a medieval inhumation cemetery dated AD 1300-1600. Prenatal and postnatal enamel formation time, neonatal line width, and the number of accentuated lines were measured using an optical microscope. The significantly wider neonatal line and the higher frequency of accentuated lines in the enamel of the incisors of children who died at the age of 2-3 years suggest the occurrence of stronger or more frequent stress events in this group. These results indicate that in skeletal populations mortality was not exclusively determined by random external factors. Individuals predisposed by an unfavorable course of prenatal and perinatal growth were more likely to die in early childhood.

    Full Text Available Abstract Background Pneumonia is among the main causes of illness and death in children Methods From July 2004 to June 2007, we examined nasopharyngeal aspirates (NPA from 2,230 cases of pneumonia (World Health Organization criteria in children 2 to 35 months old recruited in a randomized trial of zinc supplementation at a field clinic in Bhaktapur, Nepal. The specimens were examined for respiratory syncytial virus (RSV, influenza virus type A (InfA and B (InfB, parainfluenza virus types 1, 2 and 3 (PIV1, PIV2, and PIV3, and human metapneumovirus (hMPV using a multiplex reverse transcriptase polymerase chain reaction (PCR assay. Results We identified 919 virus isolates in 887 (40.0% of the 2,219 NPA specimens with a valid PCR result, of which 334 (15.1% yielded RSV, 164 (7.4% InfA, 129 (5.8% PIV3, 98 (4.4% PIV1, 93 (4.2% hMPV, 84 (3.8% InfB, and 17 (0.8% PIV2. CAP occurred in an epidemic pattern with substantial temporal variation during the three years of study. The largest peaks of pneumonia occurrence coincided with peaks of RSV infection, which occurred in epidemics during the rainy season and in winter. The monthly number of RSV infections was positively correlated with relative humidity (rs = 0.40, P = 0.01, but not with temperature or rainfall. An hMPV epidemic occurred during one of the three winter seasons and the monthly number of hMPV cases was also associated with relative humidity (rs = 0.55, P = 0.0005. Conclusion Respiratory RNA viruses were detected from NPA in 40% of CAP cases in our study. The most commonly isolated viruses were RSV, InfA, and PIV3. RSV infections contributed substantially to the observed CAP epidemics. The occurrence of viral CAP in this community seemed to reflect more or less overlapping micro-epidemics with several respiratory viruses, highlighting the challenges of developing and implementing effective public health control measures.

    Despite the existence of low-cost and effective interventions for childhood pneumonia and diarrhoea, these conditions remain two of the leading killers of young children. Based on feedback from health professionals in countries with high child mortality, in 2009, WHO and Unicef began conceptualising an integrated approach for pneumonia and diarrhoea control. As part of this initiative, WHO and Unicef, with support from other partners, conducted a series of five workshops to facilitate the inclusion of coordinated actions for pneumonia and diarrhoea into the national health plans of 36 countries with high child mortality. This paper presents the findings from workshop and post-workshop follow-up activities and discusses the contribution of these findings to the development of the integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea, which outlines the necessary actions for elimination of preventable child deaths from pneumonia and diarrhoea by 2025. Though this goal is ambitious, it is attainable through concerted efforts. By applying the lessons learned thus far and continuing to build upon them, and by leveraging existing political will and momentum for child survival, national governments and their supporting partners can ensure that preventable child deaths from pneumonia and diarrhoea are eventually eliminated.

    Full Text Available Community-acquired pneumonia (CAP is the leading cause of under-five mortality globally with almost one-quarter of deaths occurring in India.To identify predisposing, enabling and service-related factors influencing treatment delay for CAP in rural communities of two states in India. Factors investigated included recognition of danger signs of CAP, health care decision making, self-medication, treatment and referral by local practitioners, and perceptions about quality of care.Qualitative research employing case studies (CS of care-seeking, key informant interviews (KII, semi-structured interviews (SSI and focus group discussions (FGD with both video presentations of CAP signs, and case scenarios. Interviews and FGDs were conducted with parents of under-five children who had suffered CAP, community health workers (CHW, and rural medical practitioners (RMP.From September 2013 to January 2014, 30 CS, 43 KIIs, 42 SSIs, and 42 FGDs were conducted. Recognition of danger signs of CAP among caregivers was poor. Fast breathing, an early sign of CAP, was not commonly recognized. Chest in-drawing was recognized as a sign of serious illness, but not commonly monitored by removing a child's clothing. Most cases of mild to moderate CAP were brought to RMP, and more severe cases taken to private clinics in towns. Mothers consulted local RMP directly, but decisions to visit doctors outside the village required consultation with husband or mother-in-law. By the time most cases reached a public tertiary-care hospital, children had been ill for a week and treated by 2-3 providers. Quality of care at government facilities was deemed poor by caregivers.To reduce CAP-associated mortality, recognition of its danger signs and the consequences of treatment delay needed to be better recognized by caregivers, and confidence in government facilities increased. The involvement of RMP in community based CAP programs needs to be investigated further given their widespread

    -terminal provasopressin (copeptin, and C-reactive protein (CRP, as well as Sequential Organ Failure Assessment (SOFA scores, are associated with severity and described as predictors of outcome in ventilator-associated pneumonia (VAP. This study sought to compare the predictive value of these biomarkers for mortality in VAP. METHODS: An observational study of 71 patients with VAP. Levels of procalcitonin, MR-proANP, copeptin, and CRP, together with SOFA scores, were determined at VAP onset, designated day 0 (D0, and on day 4 of treatment (D4. Patients received empirical antimicrobial therapy, with modifications based on culture results. Patients who died before D28 were classified as nonsurvivors. RESULTS: Of the 71 patients evaluated, 45 were classified as survivors. Of the 45 survivors, 35 (77.8% received appropriate antimicrobial therapy, compared with 18 (69.2% of the 26 nonsurvivors (p = 0.57. On D0 and D4, the levels of all biomarkers (except CRP, as well as SOFA scores, were lower in eventual survivors than in eventual nonsurvivors. For D0 and D4, the area under the ROC curve was largest for procalcitonin. On D0, MR-proANP had the highest positive likelihood ratio (2.71 and positive predictive value (0.60, but procalcitonin had the highest negative predictive value (0.87. On D4, procalcitonin had the highest positive likelihood ratio (3.46, the highest positive predictive value (0.66, and the highest negative predictive value (0.93. CONCLUSIONS: The biomarkers procalcitonin, MR-proANP, and copeptin can predict mortality in VAP, as can the SOFA score. Procalcitonin alone has the greatest predictive power for such mortality.

    Klebsiella pneumoniae is an important cause of community-onset pneumonia in Asian countries and South Africa. We investigated the clinical characteristics of K. pneumoniae causing community-onset pneumonia, and the associated microbiological features between K. pneumoniae isolates from pneumonia and those from the nasopharynx in Taiwan. This study was conducted at the Taipei Veterans General Hospital during July, 2012 to February, 2014. The clinical characteristics in patients with community-onset K. pneumoniae pneumonia were analyzed. K. pneumoniae isolates from the nasopharynx of adults attending otorhinolaryngology outpatient clinics were collected to compare their microbiological features with those from pneumonia. Capsular genotypes, antimicrobial susceptibility, and multilocus sequence type (MLST) were determined among these strains. Ninety-one patients with community-onset K. pneumoniae pneumonia were enrolled. We found a high mortality (29.7%) among these patients. Capsular types K1, K2, K5, K20, K54, and K57 accounted for ∼70% of the K. pneumoniae isolates causing pneumonia, and ∼70% of all the K. pneumoniae strains isolated from the nasopharynx of patients in outpatient clinics. The MLST profiles further demonstrated the genetic relatedness between most pneumonia isolates and those from the nasopharynx. In conclusion, our results show that community-onset pneumonia caused by K. pneumoniae was associated with high mortality and could have a reservoir in the nasopharynx. To tackle this high-mortality disease, the distribution of capsular types in the nasopharynx might have implications for future vaccine development.

    In Nigeria, approximately 109 million and 66 million people lack access to sanitation facilities and water, respectively. This study aimed to determine whether children under 5 years old without access to improved water and sanitation facilities are at higher risk of death in Nigeria. Pooled 2003, 2008 and 2013 Nigeria Demographic and Health Survey data were used to examine the impact of water and sanitation on deaths of children aged 0-28 days, 1-11 months, and 12-59 months using Cox regression analysis. Survival information of 63,844 children was obtained, which included 6285 deaths of children under 5 years old; there were 2254 cases of neonatal mortality (0-28 days), 1859 cases of post-neonatal mortality (1-11 months) and 2,172 cases of child mortality (1-4 years old). Over a 10-year period, the odds of neonatal, post-neonatal and child deaths significantly reduced by 31%, 41% and 47% respectively. The risk of mortality from both unimproved water and sanitation was significantly higher by 38% (Adjusted hazard ratios (HR) = 1.38, 95% confidence interval (CI): 1.14-1.66) for post-neonatal mortality and 24% (HR = 1.24, 95% CI: 1.04-1.48) for child mortality. The risk of neonatal mortality increased by 6% (HR = 1.06, 95% CI: 0.85-1.23) but showed no significant effect. The Nigerian government needs to invest more in water and sanitation to reduce preventable child deaths.

    Objective To determine whether modern treatments for cancer are associated with a net increased or decreased risk of death from neoplastic and non-neoplastic causes among survivors of childhood cancer. Design Population based cohort study. Setting British Childhood Cancer Survivor Study. Participants Nationwide population based cohort of 34 489 five year survivors of childhood cancer with a diagnosis from 1940 to 2006 and followed up until 28 February 2014. Main outcome measures Cause specific standardised mortality ratios and absolute excess risks are reported. Multivariable Poisson regression models were utilised to evaluate the simultaneous effect of risk factors. Likelihood ratio tests were used to test for heterogeneity or trend. Results Overall, 4475 deaths were observed, which was 9.1 (95% confidence interval 8.9 to 9.4) times that expected in the general population, corresponding to 64.2 (95% confidence interval 62.1 to 66.3) excess deaths per 10 000 person years. The number of excess deaths from all causes declined among those treated more recently; those treated during 1990-2006 experienced 30% of the excess number of deaths experienced by those treated before 1970. The corresponding percentages for the decline in excess deaths from recurrence or progression and non-neoplastic causes were 30% and 60%, respectively. Among survivors aged 50-59 years, 41% and 22% of excess deaths were attributable to subsequent primary neoplasms and circulatory conditions, respectively, whereas the corresponding percentages among those aged 60 years or more were 31% and 37%. Conclusions The net effects of changes in cancer treatments, and surveillance and management for late effects, over the period 1940 to 2006 was to reduce the excess number of deaths from both recurrence or progression and non-neoplastic causes among those treated more recently. Among survivors aged 60 years or more, the excess number of deaths from circulatory causes exceeds the excess number

    Zinc is an essential micronutrient important for growth and for normal function of the immune system. Many children in developing countries have inadequate zinc nutrition. Routine zinc supplementation reduces the risk of respiratory infections and diarrhea, the two leading causes of morbidity and mortality in young children worldwide. In childhood diarrhea oral zinc also reduces illness duration and risk of persistent episodes. Oral zinc is therefore recommended for the treatment of acute diarrhea in young children. The results from the studies that have measured the therapeutic effect of zinc on acute respiratory infections, however, are conflicting. Moreover, the results of therapeutic zinc for childhood malaria also are so far not promising.This paper gives a brief outline of the current evidence from clinical trials on therapeutic effect of oral zinc on childhood respiratory infections, pneumonia and malaria and also of new evidence of the effect on serious bacterial illness in young infants.

    The burden of severe pneumonia in terms of morbidity and mortality is unknown in India especially at sub-national level. In this context, we aimed to estimate the number of severe pneumonia episodes, pneumococcal pneumonia episodes and pneumonia deaths in children younger than 5 years in 2010. We adapted and parameterized a mathematical model based on the epidemiological concept of potential impact fraction developed CHERG for this analysis. The key parameters that determine the distribution of severe pneumonia episode across Indian states were state-specific under-5 population, state-specific prevalence of selected definite pneumonia risk factors and meta-estimates of relative risks for each of these risk factors. We applied the incidence estimates and attributable fraction of risk factors to population estimates for 2010 of each Indian state. We then estimated the number of pneumococcal pneumonia cases by applying the vaccine probe methodology to an existing trial. We estimated mortality due to severe pneumonia and pneumococcal pneumonia by combining incidence estimates with case fatality ratios from multi-centric hospital-based studies. Our results suggest that in 2010, 3.6 million (3.3-3.9 million) episodes of severe pneumonia and 0.35 million (0.31-0.40 million) all cause pneumonia deaths occurred in children younger than 5 years in India. The states that merit special mention include Uttar Pradesh where 18.1% children reside but contribute 24% of pneumonia cases and 26% pneumonia deaths, Bihar (11.3% children, 16% cases, 22% deaths) Madhya Pradesh (6.6% children, 9% cases, 12% deaths), and Rajasthan (6.6% children, 8% cases, 11% deaths). Further, we estimated that 0.56 million (0.49-0.64 million) severe episodes of pneumococcal pneumonia and 105 thousand (92-119 thousand) pneumococcal deaths occurred in India. The top contributors to India's pneumococcal pneumonia burden were Uttar Pradesh, Bihar, Madhya Pradesh and Rajasthan in that order. Our results

    Full Text Available A case-control study, involving patients with positive blood cultures for Klebsiella pneumoniae (KP or Escherichia coli (EC EC and controls with positive blood cultures for non-ESBL-KP or EC, was performed to assess risk factors for extended-spectrum-β-lactamase (ESBL production from nosocomial bloodstream infections (BSIs. Mortality among patients with BSIs was also assessed. The study included 145 patients (81, 59.5% with K. pneumoniae and 64, 44.1% with E. coli BSI; 51 (35.2% isolates were ESBL producers and 94 (64.8% nonproducers. Forty-five (55.6% K. pneumoniae isolates were ESBL producers, while only six (9.4% E. coli isolates produced the enzyme. Multivariate analysis showed that recent exposure to piperacillin-tazobactam (adjusted Odds Ratio [aOR] 6.2; 95%CI 1.1-34.7 was a risk factor for ESBL BSI. K. pneumoniae was significantly more likely to be an ESBL-producing isolate than E. coli (aOR 6.7; 95%CI 2.3-20.2. No cephalosporin class was independently associated with ESBLs BSI; however, in a secondary model considering all oxymino-cephalosporins as a single variable, a significant association was demonstrated (aOR 3.7; 95%CI 1.3-10.8. Overall 60-day mortality was significantly higher among ESBL-producing organisms. The finding that piperacillin-tazobactam use is a risk factor for ESBL-production in KP or EC BSIs requires attention, since this drug can be recommended to limit the use of third-generation cephalosporins.Estudo de caso-controle, onde os casos foram pacientes com hemocultura positiva para Klebsiella pneumoniae (KP ou Escherichia coli (EC produtores de beta lactamase de espectro estendido (ESBL e os controles foram pacientes com hemoculturas positivas para EC ou KP não produtores de ESBL foi realizado para avaliar os fatores de risco para produção destas enzimas em infecções da corrente sanguínea (ICS.

    Klebsiella pneumoniae is a common cause of nosocomial pneumonia. Osteopontin (OPN) is a phosphorylated glycoprotein involved in inflammatory processes, some of which is mediated by CD44. The aim of this study was to determine the role of OPN during K. pneumoniae-induced pneumonia. Wild-type (WT) and OPN knockout (KO) mice were intranasally infected with 10⁴ colony forming units of K. pneumoniae, or administered Klebsiella lipopolysaccharides (LPS). In addition, recombinant OPN (rOPN) was intranasally administered to WT and CD44 KO mice. During Klebsiella pneumonia, WT mice displayed elevated pulmonary and plasma OPN levels. OPN KO and WT mice showed similar pulmonary bacterial loads 6 h after infection; thereafter, Klebsiella loads were higher in lungs of OPN KO mice and the mortality rate in this group was higher than in WT mice. Early neutrophil recruitment into the bronchoalveolar space was impaired in the absence of OPN after intrapulmonary delivery of either Klebsiella bacteria or Klebsiella LPS. Moreover, rOPN induced neutrophil migration into the bronchoalveolar space, independent from CD44. In vitro, OPN did not affect K. pneumoniae growth or neutrophil function. In conclusion, OPN levels were rapidly increased in the bronchoalveolar space during K. pneumoniae pneumonia, where OPN serves a chemotactic function towards neutrophils, thereby facilitating an effective innate immune response.

    Reported are the results of an analysis of mortality trends from diarrhoeal diseases among under-5-year-olds in Mexico between 1978 and 1993 in relation to the impact of education, basic sanitation, and selected medical care practices. The study period was divided into three stages; the first pre-dated the widespread application of oral rehydration therapy (ORT); the second, covered the implementation of a nationwide programme promoting ORT; and the third included additional measures, such as immunization and improvements in basic sanitation. Mortality rates decreased progressively, at an average of 1.8% per year in the first stage, 6.4% in the second, and 17.8% in the third. The importance of literacy campaigns for women and the promotion of ORT was confirmed. Both of these measures reduced mortality; however, a greater reduction resulted from a massive immunization campaign against measles and improvements in sanitation (expansion of the drainage and piped water systems, improved water chlorination procedure, and effective prohibition of the use of sanitary sewage for vegetable irrigation).

  12. A high burden of respiratory syncytial virus associated pneumonia in children less than two years of age in a South East Asian refugee population.

    Claudia Turner

    Full Text Available BACKGROUND: Pneumonia is a major cause of childhood mortality and morbidity approximately 1.6 million deaths and 150 million episodes occur annually in children <5 years. Respiratory syncytial virus (RSV may be responsible for up to 25% of cases and 12% of deaths making it an important potential vaccine target, although data from South East Asia is scarce. METHODS: We followed a birth cohort of Burmese refugee children, born over a one year period, for two years. Pneumonia episodes were diagnosed using WHO criteria. A chest radiograph, nasopharyngeal aspirate and non-specific markers of infection were taken during each episode. RESULTS: The incidence of RSV-associated pneumonia was 0.24 (95% CI 0.22-0.26 episodes per child year. All children with pneumonia received antibiotic treatment, following WHO guidelines. The highest incidence was in the 2-12 month age group. The commonest diagnosis in a child with RSV-associated pneumonia was non-severe pneumonia (239/362:66.0%, however the incidence of RSV-associated severe or very severe pneumonia was 0.08 (95% CI 0.01-0.10 episodes per child year. Birth in the wet season increased the risk of severe disease in children who had their first episode of RSV-associated pneumonia aged 2-11 months (OR 28.7, 95% CI 6.6-125.0, p<0.001. RSV episodes were highly seasonal being responsible for 80.0% of all the pneumonia episodes occurring each October and November over the study period. CONCLUSIONS: There was a high incidence of RSV associated pneumonia in this refugee population. Interventions to prevent RSV infection have the potential to reduce the incidence of clinically diagnosed pneumonia and hence unnecessary antibiotic usage in this population.

  13. A systematic review on the diagnosis of pediatric bacterial pneumonia: when gold is bronze.

    Tim Lynch

    Full Text Available BACKGROUND: In developing countries, pneumonia is one of the leading causes of death in children under five years of age and hence timely and accurate diagnosis is critical. In North America, pneumonia is also a common source of childhood morbidity and occasionally mortality. Clinicians traditionally have used the chest radiograph as the gold standard in the diagnosis of pneumonia, but they are becoming increasingly aware that it is not ideal. Numerous studies have shown that chest radiography findings lack precision in defining the etiology of childhood pneumonia. There is no single test that reliably distinguishes bacterial from non-bacterial causes. These factors have resulted in clinicians historically using a combination of physical signs and chest radiographs as a 'gold standard', though this combination of tests has been shown to be imperfect for diagnosis and assigning treatment. The objectives of this systematic review are to: 1 identify and categorize studies that have used single or multiple tests as a gold standard for assessing accuracy of other tests, and 2 given the 'gold standard' used, determine the accuracy of these other tests for diagnosing childhood bacterial pneumonia. METHODS AND FINDINGS: Search strategies were developed using a combination of subject headings and keywords adapted for 18 electronic bibliographic databases from inception to May 2008. Published studies were included if they: 1 included children one month to 18 years of age, 2 provided sufficient data regarding diagnostic accuracy to construct a 2x2 table, and 3 assessed the accuracy of one or more index tests as compared with other test(s used as a 'gold standard'. The literature search revealed 5,989 references of which 256 were screened for inclusion, resulting in 25 studies that satisfied all inclusion criteria. The studies examined a range of bacterium types and assessed the accuracy of several combinations of diagnostic tests. Eleven different gold

    Full Text Available Countries in Latin America were among the first to implement routine vaccination against species A rotavirus (RVA. We evaluate data from Latin America on reductions in gastroenteritis and RVA disease burden following the introduction of RVA vaccine. Published literature was reviewed to identify case-control studies of vaccine effectiveness and population-based studies examining longitudinal trends of diarrhoeal disease reduction after RVA vaccine introduction in Latin American countries. RVA vaccine effectiveness and impact on gastroenteritis mortality and hospitalization rates and RVA hospitalization rates are described. Among middle-income Latin American countries with published data (Mexico, Brazil, El Salvador and Panama, RVA vaccine contributed to a gastroenteritis-associated mortality reduction of 22-41%, a gastroenteritis-associated hospitalization reduction of 17-51% and a RVA hospitalization reduction of 59-81% among children younger than five years of age. In Brazil and El Salvador, case-control studies demonstrated that a full RVA vaccination schedule was 76-85% effective against RVA hospitalization; a lower effectiveness of 46% was seen in Nicaragua, the only low-income country with available data. A growing body of literature offers convincing evidence of "real world" vaccine program successes in Latin American settings, which may be expanded as more countries in the region include RVA vaccine in their immunization programs.

    2012-12-13

    Life expectancy has risen sharply in the last 50 years. We applied the classic Michaelis-Menten enzyme kinetics to demonstrate a novel mathematical relationship of income to childhood (aged 0-5 years) and adult (aged 15-60 years) survival. We treat income as a substrate that is catalyzed to increase survival (from technologies that income buys) for 180 countries from 1970 and 2007. Michaelis-Menten kinetics permit estimates of maximal survival and, uniquely, the critical income needed to achieve half of the period-specific maximum. Maximum child and adult survival rose by about 1% per year. Critical incomes fell by half for children, but doubled for men. HIV infection and smoking account for some, but not all, of the rising critical incomes for adult survival. Altering the future cost curve for adult survival will require more widespread use of current interventions, most notably tobacco control, but also research to identify practicable low-cost drugs, diagnostics, and strategies.DOI:http://dx.doi.org/10.7554/eLife.00051.001.

    Full Text Available Background: Appropriate and timely care seeking reduces mortality for childhood illnesses including pneumonia. Despite over 90 000 Lady Health Workers (LHWs deployed in Pakistan, whose tasks included management of pneumonia, only 16% of care takers sought care from them for respiratory infections. As part of a community case management trial for childhood pneumonia, community mobilization interventions were implemented to improve care seeking from LHWs in Haripur district, Pakistan. The objective of the study was to increase the number of children receiving treatment for pneumonia and severe pneumonia by Lady Health Workers (LHWs through community mobilization approaches for prompt recognition and care seeking in 2 to 59 month–old children. Methods: To assess pneumonia care seeking practices, pre and post– intervention household surveys were conducted in 28 target Union Councils. Formative research to improve existing LHW training materials, job aids and other materials was carried out. Advocacy events were organized, LHWs and male health promoters were trained in community mobilization, non–functional women and male health committees were revitalized and LHWs and male health promoters conducted community awareness sessions. Results: The community mobilization interventions were implemented from April 2008 – December 2009. Project and LHW program staff organized 113 sensitization meetings for opinion leaders, which were attended by 2262 males and 3288 females. The 511 trained LHWs organized 6132 community awareness sessions attended by 50 056 women and 511 male promoters conducted 523 sessions attended by 7845 males. In one year period, the number of LHWs treating pneumonia increased from 11 in April 2008 to 505 in March 2009. The care seeking from LHWs for suspected pneumonia increased from 0.7% in pre–intervention survey to 49.2% in post–intervention survey. Conclusion: The increase in care seeking from LHWs benefited the community

  19. Thirty years after Alma-Ata: a systematic review of the impact of community health workers delivering curative interventions against malaria, pneumonia and diarrhoea on child mortality and morbidity in sub-Saharan Africa

    2011-10-01

    Full Text Available Abstract Background Over thirty years have passed since the Alma-Ata Declaration on primary health care in 1978. Many governments in the first decade following the declaration responded by developing national programmes of community health workers (CHWs, but evaluations of these often demonstrated poor outcomes. As many CHW programmes have responded to the HIV/AIDS pandemic, international interest in them has returned and their role in the response to other diseases should be examined carefully so that lessons can be applied to their new roles. Over half of the deaths in African children under five years of age are due to malaria, diarrhoea and pneumonia - a situation which could be addressed through the use of cheap and effective interventions delivered by CHWs. However, to date there is very little evidence from randomised controlled trials of the impacts of CHW programmes on child mortality in Africa. Evidence from non-randomised controlled studies has not previously been reviewed systematically. Methods We searched databases of published and unpublished studies for RCTs and non-randomised studies evaluating CHW programmes delivering curative treatments, with or without preventive components, for malaria, diarrhoea or pneumonia, in children in sub-Saharan Africa from 1987 to 2007. The impact of these programmes on morbidity or mortality in children under six years of age was reviewed. A descriptive analysis of interventional and contextual factors associated with these impacts was attempted. Results The review identified seven studies evaluating CHWs, delivering a range of interventions. Limited descriptive data on programmes, contexts or process outcomes for these CHW programmes were available. CHWs in national programmes achieved large mortality reductions of 63% and 36% respectively, when insecticide-treated nets and anti-malarial chemoprophylaxis were delivered, in addition to curative interventions. Conclusions CHW programmes could

  1. Trends in childhood disease.

    Pallapies, Dirk

    2006-09-28

    Child mortality has declined remarkably during the last decades. While neonatal disorders, diarrhoea, pneumonia, and malaria as well as being underweight account for most of the child deaths worldwide, children's health discussions in Europe and the USA focus on other issues such as asthma, neurodevelopmental disorders, male genital malformations, and childhood cancer. There is clear evidence of increasing rates of asthma in various countries during the last decades, although rates in some countries may now have stabilised or even decline as recent UK data indicate. Although an increase in the frequency of neurodevelopmental disorders such as autism and attention deficit disorder has frequently been discussed, the limited data in this field does not justify such a conclusion. While geographic heterogeneity regarding reproductive outcomes is apparent, global trends have not been identified. Interpretation of the available information on asthma, neurodevelopmental disorders and reproductive outcomes is hampered by inconstant diagnostic criteria over place and time and the lack of good and comprehensive population-based surveillance data, which makes it impossible to ascertain trends in actual disease frequency. Data indicate that developed countries have a gradually increasing incidence in leukaemia with a corresponding drop in the incidence of lymphoma. Increases in brain tumour frequency may be related to the development and wide application of new diagnostic capabilities, rather than a true change in the incidence of malignant disease. With a better prognosis for childhood cancer survival, secondary cancers following chemotherapy appear to be increasing. A wide range of environmental factors is thought to have an impact on children's health. These factors include nutrition (protein, vitamins, antioxidants), lifestyle and behaviour choices such as tobacco and alcohol use, parental health, socio-economic status, choice of living environment (urban versus rural, etc

    2010-09-01

    Pneumonia is a major infectious disease associated with significant morbidity, mortality and utilisation of healthcare resources. Streptococcus pneumoniae is the predominant pathogen in community-acquired pneumonia (CAP), accounting for 20-60% of bacterial cases. Emergence of multidrug-resistant S. pneumoniae has become a significant problem in the management of CAP. Although pneumococcal conjugate vaccine usage in children has led to significant decreases in morbidity and mortality due to S. pneumoniae in all age groups, disease management has been further complicated by the unexpected increase in resistant serotypes, such as 19A, in some regions. Until rapid and accurate diagnostic tests become available, initial treatment of CAP will remain empirical. Thus, selection of appropriate antimicrobial therapy for CAP must be based on prediction of the most likely pathogens and their local antimicrobial susceptibility patterns. This article reviews information on antimicrobial resistance patterns amongst S. pneumoniae and implications for managing CAP.

    Acute pancreatitis is a rare finding in childhood but probably more common than is generally realized. This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. Patients with hereditary pancreatitis are at high risk for pancreatic cancer.

    Incidence and mortality rates of infections caused by Streptococcus pneumoniae (pneumococcus) are high worldwide and in Hungary among paediatric as well as adult populations. Pneumococci account for 35-40% of community acquired adult pneumonias requiring hospitalization, while 25-30% of Streptococcus pneumoniae pneumonias are accompanied by bacteraemia. 5-7% of all infections are fatal but this rate is exponentially higher in high risk patients and elderly people. Mortality could reach 20% among patients with severe invasive pneumococcal infections. Complications may develop despite administration of adequate antibiotics. The authors summarize the epidemiology of pneumococcal infections, pathogenesis of non-invasive and invasive disease and present basic clinical aspects through demonstration of four cases. Early risk stratification, sampling of hemocultures, administration of antibiotics and wider application of active immunization could reduce the mortality of invasive disease. Anti-pneumococcal vaccination is advisable for adults of ≥50 years and high risk patients of ≥18 years who are susceptible to pneumococcal disease.

  8. Intestine-specific Mttp deletion decreases mortality and prevents sepsis-induced intestinal injury in a murine model of Pseudomonas aeruginosa pneumonia.

    Directory of Open Access Journals (Sweden)

    Jessica A Dominguez

    Full Text Available BACKGROUND: The small intestine plays a crucial role in the pathophysiology of sepsis and has been referred to as the "motor" of the systemic inflammatory response. One proposed mechanism is that toxic gut-derived lipid factors, transported in mesenteric lymph, induce systemic injury and distant organ failure. However, the pathways involved are yet to be defined and the role of intestinal chylomicron assembly and secretion in transporting these lipid factors is unknown. Here we studied the outcome of sepsis in mice with conditional, intestine-specific deletion of microsomal triglyceride transfer protein (Mttp-IKO, which exhibit a block in chylomicron assembly together with lipid malabsorption. METHODOLOGY/PRINCIPAL FINDINGS: Mttp-IKO mice and controls underwent intratracheal injection with either Pseudomonas aeruginosa or sterile saline. Mttp-IKO mice exhibited decreased seven-day mortality, with 0/20 (0% dying compared to 5/17 (29% control mice (p<0.05. This survival advantage in Mttp-IKO mice, however, was not associated with improvements in pulmonary bacterial clearance or neutrophil infiltration. Rather, Mttp-IKO mice exhibited protection against sepsis-associated decreases in villus length and intestinal proliferation and were also protected against increased intestinal apoptosis, both central features in control septic mice. Serum IL-6 levels, a major predictor of mortality in human and mouse models of sepsis, were elevated 8-fold in septic control mice but remained unaltered in septic Mttp-IKO mice. Serum high density lipoprotein (HDL levels were reduced in septic control mice but were increased in septic Mttp-IKO mice. The decreased levels of HDL were associated with decreased hepatic expression of apolipoprotein A1 in septic control mice. CONCLUSIONS/SIGNIFICANCE: These studies suggest that strategies directed at blocking intestinal chylomicron secretion may attenuate the progression and improve the outcome of sepsis through effects

    Lymphocytic interstitial pneumonia (LIP) is a rare lung disease on the spectrum of benign pulmonary lymphoproliferative disorders. LIP is frequently associated with connective tissue diseases or infections. Idiopathic LIP is rare; every attempt must be made to diagnose underlying conditions when LIP is diagnosed. Computed tomography of the chest in patients with LIP may reveal ground-glass opacities, centrilobular and subpleural nodules, and randomly distributed thin-walled cysts. Demonstrating polyclonality with immunohistochemistry is the key to differentiating LIP from lymphoma. The 5-year mortality remains between 33% and 50% and is likely to vary based on the underlying disease process.

    A 63-year-old Dutch man became colonized with a carbapenem resistant Klebsiella pneumoniae during a period of hospitalization in India. His recovery in the Netherlands was complicated by pneumonia due to this difficult-to-control multiresistant bacteria to which he eventually succumbed. Carbapenem resistance in Enterobacteriaceae, such as K. pneumoniae, is usually caused by carbapenemase (a betalactamase) production. Carbapenemase producing Enterobacteriaceae (CPE) are spreading throughout the world and cause difficult-to-treat infections that are associated with high mortality. This case report illustrates the clinical challenges associated with infection with these multiresistant Enterobacteriaceae. In the Netherlands, there are no guidelines for detection of CPE and carbapenemase production can frequently go undetected in clinical microbiology laboratories. As a consequence, adequate treatment of CPE infections and infection control measures to prevent the spread of CPE can be delayed. Expeditious development and implementation of existing Dutch draft guidelines for detection methods of CPE is therefore warranted.

    Klebsiella pneumoniae producing KPC-type carbapenemase causes severe nosocomial infection at a high mortality rate. Nosocomial pneumonia in particular is associated with high mortality, likely due to the unfavorable pulmonary pharmacokinetics of the antibiotics used against this agent. Therefore, early and accurate microbiological identification and susceptibility evaluation are crucial in order to optimize antibiotic therapy. We report a case of ventilator-associated pneumonia caused by colistin-resistant K. pneumoniae producing KPC-type carbapenemase treated using a carbapenem-sparing therapy and tailored according to the serum procalcitonin concentration in order to limit the duration of antibiotic therapy.

    Nursing home-acquired pneumonia (NHAP) was first described in 1978. Since then there has been much written regarding NHAP and its management despite the lack of well-designed studies in this patient population. The most characteristic features of patients with NHAP are the atypical presentation, which may lead to delay in diagnosis and therapy. The microbial etiology of pneumonia encompasses a wide spectrum that spans microbes recovered from patients with community-acquired pneumonia to organisms considered specific only to nosocomial settings. Decision to transfer a nursing home patient to an acute care facility depends on a host of factors, which include the level of staffing available at the nursing home, patients' advance directives, and complexity of treatment. The presence of risk factors for multidrug-resistant pathogens dictates approach to therapy. Prevention remains the cornerstone of reducing the incidence of disease. Despite the advance in medical services, mortality from NHAP remains high.

    Pneumonia remains a significant cause of morbidity and mortality in the UK and yet the seriousness of the disease is underestimated. Pneumonia can be life-threatening because the delicate tissues of the alveoli and pulmonary capillaries are susceptible to damage from the inflammatory response. This damage leads to consolidation that prevents the diffusion of oxygen and carbon dioxide, and this in turn can lead to respiratory failure. This article summarises guidance on the diagnosis and management of community-acquired pneumonia, and also includes information on the prevention of pneumonia. This information should be valuable to nurses working in a variety of clinical areas since patients with community-acquired pneumonia are encountered in primary, intermediate, secondary and critical care.

    Full Text Available Introduction: Pneumonia is one of the most common infections during childhood. In children with recurrent bacterial pneumonia complete evaluation for underlying factors is necessary. The most common underlying diseases include: antibody deficiencies , cystic fibrosis , tracheoesophageal fistula and increased pulmonary blood flow. Vascular ring and its pressure effect is a less common cause of stridor and recurrent pneumonia. Congenital abnormalities in aortic arch and main branches which form vascular ring around esophagus and trachea with variable pressure effect cause respiratory symptoms such as stridor , wheezing and recurrent pneumoniaCase Report: A 2 year old boy was admitted in our hospital with respiratory distress and cough . Chest x-Ray demonstrated right lobar pneumonia. He had history of stridor and wheezing from neonatal period and hospitalization due to pneumonia for four times. The patient received appropriate antibiotics. Despite fever and respiratory distress improvement, wheezing continued. Review of his medical documents showed fixed pressure effect on posterior aspect of esophagus in barium swallow. In CT angiography we confirmed double aortic arch.Conclusion: Double aortic arch is one of the causes of persistant respiratory symptom and recurrent pneumonia in children for which fluoroscopic barium swallow is the first non-invasive diagnostic method.(Sci J Hamadan Univ Med Sci 2012;19(1:70-74

    Pneumonia is a major cause of morbidity and mortality leading to a high rate of hospitalization especially in theelderly. It is often a sign of frailty and is associated with a poor prognosis. However, taking into account the geriatric specificities (risk factors, atypical clinical presentations with "geriatric syndromes", ethical debate) using an interdisciplinary and a comprehensive geriatric approach remains an important responsibility of the general practitionner. This article summarizes these specificities and offers interventions targeted on the characteristics of elderly patients.

    2011-08-01

    Health care-associated pneumonia is a relatively new classification of pneumonia that includes community-dwelling pneumonia patients having contact with the health care system. Current data indicate that health care-associated pneumonia patients present with more severe disease, are more likely to be infected with drug-resistant pathogens, and suffer increased mortality compared with community-acquired pneumonia patients. Guidelines recommend that these patients receive empiric antibiotics similar to those recommended for nosocomial pneumonia; however, it is not currently known if outcomes are improved when health care-associated pneumonia patients are treated with these therapies. In addition, the individual health care-associated pneumonia risk factors are based on limited data and are a poor predictor of patients likely to be infected with drug-resistant pathogens. Many questions remain on how to most appropriately care for this growing group of pneumonia patients. This review is an evidence-based discussion of current health care-associated pneumonia data, the individual health care-associated pneumonia risk factors, and limitations and additional considerations for the health care-associated pneumonia classification system.

    Full Text Available Introduction: Pneumococcal infections are important cause of morbidity and mortality. Knowledge of antimicrobial susceptibility patterns plays important role in the selection of appropriate therapy. Present study was undertaken to analyze the susceptibility patterns of pneumococcal isolates against commonly used antimicrobials with special reference to determination of minimum inhibitory concentration (MIC of penicillin in a tertiary care hospital in eastern Nepal. Methods: Twenty-six strains of S. pneumoniae isolated from various clinical specimens submitted to microbiology laboratory were evaluated. All isolates were tested for antimicrobial susceptibility by disk diffusion method. MIC of penicillin was tested by broth dilution method. Results: Of the total isolates 19 (73% were from invasive infections. Seven isolates were resistant to cotrimoxazole. No resistance to penicillin was seen in disk diffusion testing. Less susceptibility to penicillin (MIC 0.1-1.0 mg/L was observed in five (17% isolates. High level resistance to penicillin was not detected. One isolate was multidrug resistant. Conclusions: S. pneumoniaeisolates with intermediate resistance to penicillin prevail in Tertiary Care Hospital in eastern Nepal, causing invasive and noninvasive infections. As intermediate resistance is not detected in routine susceptibility testing, determination of MIC is important. It helps not only in the effective management of life threatening infections but is also essential in continuous monitoring and early detection of resistance. In addition, further study on pneumococcal infections, its antimicrobial resistance profile and correlation with clinical and epidemiological features including serotypes and group prevalence is recommended in future. Keywords: antimicrobial susceptibility pattern, penicillin, Streptococcus pneumoniae.

    OBJECTIVE To retrospectively investigate the risk factors associated the mortality of the patients with pneumonia caused by Acinetobacter baumannii and Pseudomonas aeruginosa , and focus on the impact of different antimicrobial regimens on the patients with A. baumannii pneumonia so as to guide the clinical treatment. METHODS We searched the qualified respiratory samples (including sputum and endotracheal aspirate) in the hospital during Jan 2012 to Aug 2012, and identified the cases with A. baumannii and/or P. aeruginosa positive isolates. The clinical data of the cases were reviewed and the cases were recruited when they were clinically diagnosed as pneumonia. The clinical and microbiological data of the patients were collected. logistic regression was applied to identify the risk factors of the mortality. RESULTS Totally 79 patients with pneumonia were enrolled in the study, including 46 patients infected with A. baumannii and 33 patients infected with P. aeruginosa; 29 cases died with the mortality of 36. 7%; the multivariate regression analysis showed that the respiratory frequency, blood urea nitrogen, sepsis, albumin level and use of antibiotics were the independent risk factors for the mortality of the patients with A. baumannii or P. aeruginosa pneumonia. The mortality of the patients with A. baumannii pneumonia was 50. 0% , 18. 8% of the patients with P. aeruginosa pneumonia (P = 0. 004) ; A. baumannii infection was an independent factor for the increase in mortality (OR = 4. 33, P = 0. 007). Of all the A. baumannii strains, the multidrug-resistant A. baumannii accounted for 97. 8%; the analysis of treatment program indicated that the use of single carbapenem for the primary treatment may increase the risk of mortality and that the use of other antibiotics had no significant impact on the mortality. CONCLUSION The severity of infection is the independent risk factor for the mortality of the patients with A. baumannii or P. aeruginosa pneumonia. The

    Objective To study the value of procalcitonin (PCT) level in predicting mortality and severity of community-acquired pneumonia (CAP) in the emergency department. Methods The general clinical data and in-flammatory biomarker of 114 patients with CAP were collected. The severity of CAP was assessed by PSI and CURB65 score. An analysis was performed to assess the value of PCT, WBC counts, high-sensitivity C-reactive pro-tein (hs-CRP), and erythrocyte sedimentation rate (ESR) for the prediction of mortality and severity. Results 14 high-risk patients died within 28 days. Compared with the survival group, the death group had significantly increased PCT level (2. 96 ± 1. 54 vs 0. 38 ± 0. 24 ng/ mL, P < 0. 01) and hs-CRP(194. 61 ± 72. 80 vs 101. 26 ± 65. 98 mg/ L, P < 0. 01). The PCT level was significantly higher in the severe group than in the moderate group according to PSI and CURB65 score. Through logistic regression analyses, the area under the receiver operating characteristic curve (ROC) of PCT level were 0. 81. The area under ROC increased significantly while it used PCT combined with PSI and CURB65 score to predict the mortality and severity of CAP. Conclusion The level of PCT is a more versatile tool for predicting mortality and severity of CAP in the emergence department, and the level of procalcitonin as an ad-junct to CAP prediction rules may be valuable for prognosis and severity assessment.%目的:探索降钙素原(PCT)对社区获得性肺炎(CAP)患者的死亡率和病情评估的价值。方法前瞻性研究在急诊科通过症状和 X 线检查诊断为 CAP 的114例患者,收集患者的一般临床资料及炎症标志物。采用肺炎严重性指数(PSI)、CURB65评分评估 CAP 患者的疾病严重性,分析血沉(ESR)、白细胞计数、高敏 C 反应蛋白(Hs-CRP)及 PCT 预测 CAP 患者死亡率和疾病严重性的价值。结果114例患者中14例高危患者28天内死亡。死亡组较存活组 PCT 和 Hs-CRP

    There is an increased susceptibility and mortality in the elderly due to pneumonia caused by Streptococcus pneumoniae. We aimed to assess the inflammatory cell composition with respect to age in pneumococcal pneumonia patients. Neutrophilic granulocytes and various lymphocyte and macrophage subpopulations were immunohistochemically quantified on lung tissue specimens of young (n = 5; mean age 8.4 years), middle-aged (n = 8; mean age 55.9 years) and elderly (n = 9; mean age 86.6 years) pneumonia patients with microbiologically proven S. pneumoniae pneumonia. We discovered a higher percentage of neutrophilic granulocytes in elderly as opposed to young patients (95 vs. 75%, p = 0.012). Conversely, young patients versus elderly patients had more alveolar macrophages (CD11c+: 20 vs. 9%, p = 0.029) and M1 macrophages (CD14+: 30 vs. 10%, p = 0.012 and HLA-DR+: 52 vs. 11%, p = 0.019). There was no significant difference concerning M2 macrophages and lymphocytes. Comparison of young patients with middle-aged patients showed similar significant results for alveolar macrophages (p = 0.019) and subsignificant results for M1 macrophages and neutrophilic granulocytes (p pneumonia in situ. Our observations improve the understanding of the innate immune mechanisms of pneumococcal lung infection and point at the potential of therapies for restoring macrophage function and decreasing neutrophilic influx in order to help prevent or cure pneumonia.

    Compared with community-dwelling persons, residents in long-term care facilities have more functional disabilities and underlying medical illnesses and are at increased risk of acquiring infectious diseases. Pneumonia is the leading cause of morbidity and mortality in this group. Risk factors include unwitnessed aspiration, sedative medication, and comorbidity. Recognition may be delayed because, in this population, pneumonia often presents without fever, cough, or dyspnea. Accurate identification of the etiologic agent is hampered because most patients cannot produce a suitable sputum specimen. It is difficult to distinguish colonization from infection. Colonization by Staphylococcus aureus and gram-negative organisms can result from aspiration of oral or gastric contents, which could lead to pneumonia. Aspiration of gastric contents also can produce aspiration pneumonitis. This condition is not infectious initially and may resolve without antibiotics. Antibiotics for the treatment of pneumonia should cover Streptococcus pneumoniae, Haemophilus influenzae, gram-negative rods, and S. aureus. Acceptable choices include quinolones or an extended-spectrum beta-lactam plus a macrolide. Treatment should last 10 to 14 days. Pneumonia is associated with significant mortality for up to two years. Dementia is related independently to the death rate within the first week after pneumonia, regardless of treatment. Prevention strategies include vaccination against S. pneumoniae and influenza on admission to the care facility. This article focuses on recent recommendations for the recognition of respiratory symptoms and criteria for the designation of probable pneumonia, and provides a guide to hospitalization, antibiotic use, and prevention.

    OBJECTIVE To explore the drug resistance of Pseudomonas aeruginosa causing pneumonia and the related risk factors for mortality. METHODS This prospective cohort clinical study was conducted in a tertiary surgical intensive care unit (SICU) in Zhongshan Hospital, Fudan University. From Jan 2007 to Dec 2010. a total of 53 patients who underwent endotracheal intubation and ventilated for more than 48 hours and were with positive culture of P. aeruginosa were enrolled in this study; the drug susceptibility testing was performed by KB method. The vital signs, ventilation parameters, treatment regiments of the patients were recorded, the follow-up of the mortality within 28 days was carried out. RESULTS Of 8 commonly used antibiotics against P. aeruginosa, amikacin was with the lowest resistance rate of 15. 1%, followed by cefoperazone/sulbactam, meropenem, ceftazidime, cefepime, and imipenem) the resistance rate to piperacillin/tazobactam was the highest (47. 2%), the multidrug-resistant rate was 32.1% ; of 53 patients, 17 patients died and 11 patients died within 28 days; the drug resistance rates of P. aeruginosa to piperacillin/tazobactam and imipenem and the multidrug-resistance rate were much higher in death group than in the survival group (76. 5% vs 33. 3%, 58. 8% vs 27. 8%, and 58. 8% vs. 19.4%, respectively) (P<0. 05). There was significant difference between survivors and non-survivors for age (75. 5 vs 56. 0 respectively) (P<0. 05); of the patients in the death group, the survival days of the patients resistant to imipenem were less than those of the patients without imipenem-resistance (P=0. 025) ; multivariate logistic regression analysis showed that there was significant correlation between the age, duration of mechanical ventilation, multidrug-resistance of P. aeruginosa, resistance to piperacillin/tazobactam and the mortality. CONCLUSION For the dead patients,the survival days of imipenem-resistant patients are significantly shortened) the age, duration

    Full Text Available Rationale. Pneumonia is a leading cause of postoperative complication. Objective. To examine trends, factors, and mortality of postoperative pneumonia following major cancer surgery (MCS. Methods. From 1999 to 2009, patients undergoing major forms of MCS were identified using the Nationwide Inpatient Sample (NIS, a Healthcare Cost and Utilization Project (HCUP subset, resulting in weighted 2,508,916 patients. Measurements. Determinants were examined using logistic regression analysis adjusted for clustering using generalized estimating equations. Results. From 1999 to 2009, 87,867 patients experienced pneumonia following MCS and prevalence increased by 29.7%. The estimated annual percent change (EAPC of mortality after MCS was −2.4% (95% CI: −2.9 to −2.0, P<0.001; the EAPC of mortality associated with pneumonia after MCS was −2.2% (95% CI: −3.6 to 0.9, P=0.01. Characteristics associated with higher odds of pneumonia included older age, male, comorbidities, nonprivate insurance, lower income, hospital volume, urban, Northeast region, and nonteaching status. Pneumonia conferred a 6.3-fold higher odd of mortality. Conclusions. Increasing prevalence of pneumonia after MCS, associated with stable mortality rates, may result from either increased diagnosis or more stringent coding. We identified characteristics associated with pneumonia after MCS which could help identify at-risk patients in order to reduce pneumonia after MCS, as it greatly increases the odds of mortality.

    Pneumonia is a major and life-threatening complication after cardiovascular surgery. The objective of our study was to describe epidemiology, clinical characteristics, and risk factors of pneumonia after cardiovascular surgery. From January 2007 to December 2011, 511 consecutive patients (age 67.3±11.9;336 men, 175 women) were enrolled in this study. Pneumonia was diagnosed according to Centers of Disease Control and Prevention surveillance criteria for healthcare associated infection. Data collection included preoperative, intraoperative, and post-operative variables. The overall incidence of pneumonia was 72 cases(14.0%). The mortality in pneumonia group was significantly higher than that in non-pneumonia group (16.6% vs 4.3%, Odds ratio 4.4 ppneumonia after cardiovascular surgery.

    Experimental pneumonia was produced in calves by the endobronchial inoculation of pneumonic lung homogenates. Irradiated homogenates produced minimal pneumonia. Ampicillin treatment of the homogenates and the experimental calves reduced the extent of pneumonia. Treatment with tylosin tartrate prevented experimental pneumonia. These results suggest that the total pneumonia was due to organisms susceptible to tylosin tartrate and that the residual pneumonia remaining after ampicillin treatment was due to organisms susceptible to tylosin tartrate but not to ampicillin. Of the organisms isolated from the lungs, the ones in this latter category most likely to be responsible are Mycoplasma dispar and ureaplasmas (T-mycoplasmas).

    Streptococcus pneumoniae is a major cause of childhood morbidity and mortality worldwide with increasing antimicrobial resistance. 600 randomly chosen asymptomatic healthy children aged 2-60 months attending Alexandria University Children's Hospital were evaluated for prevalence of nasopharyngeal (NP) carriage of S. pneumoniae. Prevalence of NP carriage was 29.2% (n = 175/600) Capsular serotyping was done using Quellung reaction. Vaccine covered serotypes (VST) represented 67.4% while non-vaccine serotypes (NVST) were 32.6%. The most common VST isolated were 19F (24.6%), 6B (14.3%) and 6A (10.9%). Confirmation of serotyping was performed by multiplex PCR which showed 100% concordance with the Quellung reaction. Antimicrobial susceptibility testing showed penicillin non-susceptibility of 15% (using non-meningitis penicillin MIC breakpoints) and 55% (using meningitis penicillin MIC breakpoints). Highest resistance was found in sulphamethoxazole-trimethoprim (55%), tetracyclins (49%), erythromycin (40%) and clindamycin (25%). This study revealed the epidemiological importance to evaluate regularly the prevalence, serotypes and the increasing antimicrobial resistance of S. pneumoniae in the community.

    Background Mycoplasma pneumoniae and Chlamydia pneumoniae are atypical pathogens responsible for pneumonia and a leading cause of morbidity and mortality in low income countries. The study objective is to determine the prevalence of this pathogens in Peruvian children with acute respiratory infections. Methods A consecutive cross-sectional study was conducted in Lima, Peru from May 2009 to September 2010. A total of 675 children admitted with clinical diagnoses of acute respiratory infections were tested for Mycoplasma pneumoniae and Chlamydia pneumoniae detection by polymerase chain reaction (PCR), and clinical symptoms were registered by the attending physician. Results Mycoplasma pneumonia was detected in 25.19% (170/675) of nasopharyngeal samples and Chlamydia pneumonia in 10.52% (71/675). The most common symptoms in patients with these atypical pathogens were rhinorrhea, cough and fever. A higher prevalence of Mycoplasma pneumoniae cases were registered in summer, between December 2009 and March 2010. Conclusions Mycoplasma pneumoniae and Chlamydia pneumonia are a significant cause of morbidity in Peruvian children with acute respiratory infections (ARI). Further studies should evaluate the use of reliable techniques such as PCR in Peru in order to avoid underdiagnoses of these atypical pathogens. PMID:28129377

    Streptococcus pneumoniae is a common cause of pneumonia and sepsis. Toll-like receptors (TLRs) play a pivotal role in the host defense against infection. In this study, we sought to determine the role of single immunoglobulin interleukin-1 receptor-related molecule (SIGIRR a.k.a. TIR8), a negative regulator of TLR signaling, in pneumococcal pneumonia and sepsis. Wild-type and SIGIRR-deficient (sigirr-/-) mice were infected intranasally (to induce pneumonia) or intravenously (to induce primary sepsis) with S. pneumoniae and euthanized after 6, 24, or 48 h for analyses. Additionally, survival studies were performed. sigirr-/- mice showed delayed mortality during lethal pneumococcal pneumonia. Accordingly, sigirr-/- mice displayed lower bacterial loads in lungs and less dissemination of the infection 24 h after the induction of pneumonia. SIGIRR deficiency was associated with increased interstitial and perivascular inflammation in lung tissue early after infection, with no impact on neutrophil recruitment or cytokine production. sigirr-/- mice also demonstrated reduced bacterial burdens at multiple body sites during S. pneumoniae sepsis. sigirr-/- alveolar macrophages and neutrophils exhibited an increased capacity to phagocytose viable pneumococci. These results suggest that SIGIRR impairs the antibacterial host defense during pneumonia and sepsis caused by S. pneumoniae.

    Bighorn sheep mortality related to pneumonia is a primary factor limiting population recovery across western North America, but management has been constrained by an incomplete understanding of the disease. We analysed patterns of pneumonia-caused mortality over 14 years in 16 interconnected bighorn sheep populations to gain insights into underlying disease processes. 2. We observed four age-structured classes of annual pneumonia mortality patterns: all-age, lamb-only, secondary all-age and adult-only. Although there was considerable variability within classes, overall they differed in persistence within and impact on populations. Years with pneumonia-induced mortality occurring simultaneously across age classes (i.e. all-age) appeared to be a consequence of pathogen invasion into a naïve population and resulted in immediate population declines. Subsequently, low recruitment due to frequent high mortality outbreaks in lambs, probably due to association with chronically infected ewes, posed a significant obstacle to population recovery. Secondary all-age events occurred in previously exposed populations when outbreaks in lambs were followed by lower rates of pneumonia-induced mortality in adults. Infrequent pneumonia events restricted to adults were usually of short duration with low mortality. 3. Acute pneumonia-induced mortality in adults was concentrated in fall and early winter around the breeding season when rams are more mobile and the sexes commingle. In contrast, mortality restricted to lambs peaked in summer when ewes and lambs were concentrated in nursery groups. 4. We detected weak synchrony in adult pneumonia between adjacent populations, but found no evidence for landscape-scale extrinsic variables as drivers of disease. 5. We demonstrate that there was a >60% probability of a disease event each year following pneumonia invasion into bighorn sheep populations. Healthy years also occurred periodically, and understanding the factors driving these

    Pneumonia is the second most common infection in long term care (LTC) residents and is a leading cause of death from infection in those groups of patients. Atypical presentations and fewer presenting signs and symptoms in older patients complicate diagnosis and delay initiation of adequate treatment. The aim of this study was to compare laboratory CRP levels to pneumonia severity scores, in prediction of short-term death from pneumonia. Diagnosis of pneumonia was performed according to the criteria of McGeer for the identification of pneumonia at an LTC facility. The severities of pneumonia and mortality prediction were assessed by three indices: PSI (pneumonia severity index), Missouri study index and the nursing home associated pneumonia (NHAP) severity index. A strong positive correlation was found between CRP levels and PSI (r=0.445, pnursing home acquired pneumonia is not specific, it is suggested that CRP should be performed in every patient with a suspicion of pneumonia.

  20. The radiological diagnosis of pneumonia in children

    2014-06-01

    Full Text Available Despite the importance of paediatric pneumonia as a cause of short and long-term morbidity and mortality worldwide, a reliable gold standard for its diagnosis remains elusive. The utility of clinical, microbiological and radiological diagnostic approaches varies widely within and between populations and is heavily dependent on the expertise and resources available in various settings. Here we review the role of radiology in the diagnosis of paediatric pneumonia. Chest radiographs (CXRs are the most widely employed test, however, they are not indicated in ambulatory settings, cannot distinguish between viral and bacterial infections and have a limited role in the ongoing management of disease. A standardised definition of alveolar pneumonia on a CXR exists for epidemiological studies targeting bacterial pneumonias but it should not be extrapolated to clinical settings. Radiography, computed tomography and to a lesser extent ultrasonography and magnetic resonance imaging play an important role in complicated pneumonias but there are limitations that preclude their use as routine diagnostic tools. Large population-based studies are needed in different populations to address many of the knowledge gaps in the radiological diagnosis of pneumonia in children, however, the feasibility of such studies is an important barrier.

  1. Low zinc status: a new risk factor for pneumonia in the elderly?

    2010-01-01

    Low zinc status may be a risk factor for pneumonia in the elderly. This special article reviews the magnitude of the problem of pneumonia (its prevalence, morbidity, and mortality) in the elderly, pneumonia's etiology, and the dysregulation of the immune system associated with increasing age. In addition, recent evidence from the literature is presented demonstrating that low zinc status (commonly reported in the elderly) impairs immune function, decreases resistance to pathogens, and is associated with increased incidence and duration of pneumonia, increased use and duration of antimicrobial treatment, and increased overall mortality in the elderly. Inadequate stores of zinc might, therefore, be a risk factor for pneumonia in the elderly. Randomized, double-blind, controlled studies are needed to determine the efficacy of zinc supplementation as a potential low-cost intervention to reduce morbidity and mortality due to pneumonia in this vulnerable population.

    Hixson, S; Sole, M L; King, T

    1998-02-01

    Critically ill patients who require mechanical ventilation are at high risk for development of pneumonia during the course of treatment. Ventilator-associated pneumonia leads to higher rates of mortality and morbidity, increased length of hospital stay, and higher hospital costs. The intubation that is necessary for mechanical ventilation impairs the patient's normal defense mechanisms for fighting infection. Impaired defenses, along with such risk factors as age of the patient, equipment used, and failure of the staff to wash hands increase the likelihood of colonization of the lower airways. Colonization and subsequent pneumonia commonly occurs from microaspiration of secretions from the oropharynx and gastrointestinal tract. In this article, the mechanism of microaspiration, diagnosis of ventilator-associated pneumonia, and nursing strategies to reduce the incidence of pneumonia are described.

    2009-09-01

    Extrapulmonary manifestations of Mycoplasma pneumoniae are well described, including a subset of central nervous system (CNS)-associated syndromes. In pediatric populations, frequencies of CNS sequelae occur in 0.1% to 7% of patients. Neurologic illness associated with M. pneumoniae, such as meningitis, encephalitis, polyradiculitis, Guillain-Barre, and stroke have been reported; however, the incidence of M. pneumoniae-associated organic brain syndrome is rare. We present the case of a 20-year-old midshipman with acute psychosis following resolution of M. pneumoniae pneumonia and review 6 other adult cases found in the literature. M. pneumoniae remains one of the most common causes of respiratory illnesses in the military recruit setting and therefore should always be suspected as an organic cause of mental status changes in young persons such as recruits, cadets, and midshipmen particularly with antecedent respiratory illnesses.

    2016-04-01

    Necrotizing fasciitis is a rapidly progressive destructive soft tissue infection with high mortality. Streptococcus pneumoniae as etiologic agent of necrotizing fasciitis is extremely unusual. The increased susceptibility to Streptococcus pneumoniae infection in patients with systemic lupus erythematosus is probably a multifactorial phenomenon. We report a case of a patient, a 36-year-old Caucasian female with 8-year history of systemic lupus erythematosus who presented a fatal Streptococcus pneumoniae necrotizing fasciitis. The role of computed tomography and the high performance of blood cultures for isolation of the causative microorganism are emphasized. Once diagnosis is suspected, empiric antibiotic treatment must be prescribed and prompt surgical exploration is mandatory.

  12. Pneumonia in immunocompetent patients: combination antibiotic therapy.

    Science.gov (United States)

    Salva, S; Borgatta, B; Rello, J

    2014-04-01

    Pneumonia's burden is still important worldwide not only because of its high incidence and mortality, but also for the elevated costs related to it. Despite the concerted efforts to reduce the incidence of sepsis-related complications, they continue to represent a major human and economic burden. The cornerstone of sepsis management is early appropriate empiric broad spectrum antibiotics, resuscitation, and source control. The association between inappropriate use of antibiotics and increased mortality is the rationale for the use of empiric antibiotic combination therapy in critically ill patients. The aim of this manuscript was to discuss recent literature regarding the management of severe pneumonia, both community-acquired and hospital-acquired/ventilator-associated, in critically ill patients. Use of combination therapy is warranted in severe infections with shock; considerations should be made on the importance of optimal antibiotic administration and adverse reactions, thus providing guidance for a rational use of antibiotics.

  13. Can We Predict Oral Antibiotic Treatment Failure in Children with Fast-Breathing Pneumonia Managed at the Community Level? A Prospective Cohort Study in Malawi.

    Directory of Open Access Journals (Sweden)

    Carina King

    Full Text Available Pneumonia is the leading cause of infectious death amongst children globally, with the highest burden in Africa. Early identification of children at risk of treatment failure in the community and prompt referral could lower mortality. A number of clinical markers have been independently associated with oral antibiotic failure in childhood pneumonia. This study aimed to develop a prognostic model for fast-breathing pneumonia treatment failure in sub-Saharan Africa.We prospectively followed a cohort of children (2-59 months, diagnosed by community health workers with fast-breathing pneumonia using World Health Organisation (WHO integrated community case management guidelines. Cases were followed at days 5 and 14 by study data collectors, who assessed a range of pre-determined clinical features for treatment outcome. We built the prognostic model using eight pre-defined parameters, using multivariable logistic regression, validated through bootstrapping.We assessed 1,542 cases of which 769 were included (32% ineligible; 19% defaulted. The treatment failure rate was 15% at day 5 and relapse was 4% at day 14. Concurrent malaria diagnosis (OR: 1.62; 95% CI: 1.06, 2.47 and moderate malnutrition (OR: 1.88; 95% CI: 1.09, 3.26 were associated with treatment failure. The model demonstrated poor calibration and discrimination (c-statistic: 0.56.This study suggests that it may be difficult to create a pragmatic community-level prognostic child pneumonia tool based solely on clinical markers and pulse oximetry in an HIV and malaria endemic setting. Further work is needed to identify more accurate and reliable referral algorithms that remain feasible for use by community health workers.

    Bacterial pneumonia is a common public health problem associated with significant mortality, morbidity, and cost. Neutrophils are usually the earliest leukocytes to respond to bacteria in the lungs. Neutrophils rapidly sequester in the pulmonary microvasculature and migrate into the lung parenchyma and alveolar spaces, where they perform numerous effector functions for host defense. Previous studies showed that migrated neutrophils produce IFN-γ early during pneumonia induced by Streptococcus pneumoniae and that early production of IFN-γ regulates bacterial clearance. IFN-γ production by neutrophils requires Rac2, Hck/Lyn/Fgr Src family tyrosine kinases, and NADPH oxidase. Our current studies examined the mechanisms that regulate IFN-γ production by lung neutrophils during acute S. pneumoniae pneumonia in mice and its function. We demonstrate that IFN-γ production by neutrophils is a tightly regulated process that does not require IL-12. The adaptor molecule MyD88 is critical for IFN-γ production by neutrophils. The guanine nucleotide exchange factor CalDAG-GEFI modulates IFN-γ production. The CD11/CD18 complex, CD44, Toll-like receptors 2 and 4, TRIF, and Nrf2 are not required for IFN-γ production by neutrophils. The recently described neutrophil-dendritic cell hybrid cell, identified by its expression of Ly6G and CD11c, is present at low numbers in pneumonic lungs and is not a source of IFN-γ. IFN-γ produced by neutrophils early during acute S. pneumoniae pneumonia induces transcription of target genes in the lungs, which are critical for host defense. These studies underline the complexity of the neutrophil responses during pneumonia in the acute inflammatory response and in subsequent resolution or initiation of immune responses.

    Lungs play an important role in the body's defense against a variety of pathogens, but this network of immune system-mediated defense can be deregulated during acute pulmonary infections. The present study compares acute lung inflammation occurring during Klebsiella pneumoniae B5055-induced pneumonia and sepsis in BALB/c mice. Pneumonia was induced by intranasal instillation of bacteria (10(4) cfu), while sepsis was developed by placing the fibrin-thrombin clot containing known amount of bacteria (10(2) cfu) into the peritoneal cavity of animals. Mice with sepsis showed 100% mortality within five post-infection days, whereas all the animals with pneumonia survived. In animals suffering from K. pneumoniae B5055-induced pneumonia, all the inflammatory parameters (TNF-α, IL-1α, MPO, MDA, and NO) were found to be maximum till third post-infection day, after that, a decline was observed, whereas in septic animals, all the above-mentioned markers of inflammation kept on increasing. Histopathological study showed presence of alternatively activated alveolar macrophages (or foam cells) in lungs of mice with pneumonia after third post-infection day, which might have contributed to the induction of resolution of inflammation, but no such observation was made in lungs of septic mice. Hence, during pneumonia, controlled activation of macrophages may lead to resolution of inflammation.

    Full Text Available Objective: Mechanical ventilator associated pneumonia is a serious infection occurred frequently in intensive care units and associated with high mortality. In this study we aimed to investigate the incidence of ventilator associated pneumonia, the duration of mechanical ventilation, length of intensive care unit stay, complication occurrence and mortality rates on patients undergoing mechanical ventilation for more than 48 hours. Material and Method: Two hundred twenty patients were included in the study. Demographic data at the time of the admission to intensive care unit (age, sex, height, weight and body mass index, intensive care admission diagnosis and systemic diseases were all recorded. The clinical pulmonary infection score was used for ventilator associated pneumonia diagnosis. Antibiotic usage, duration of stay in intensive care unit, duration of mechanical ventilation stay and mortality were all recorded. Results: Ventilator-associated pneumonia was detected in 51.36% (n=113 of the 220 patients. Clinical pulmonary infection score was found as 8.04±1.03 in patients with ventilator-associated pneumonia and 1.75±1.88 in non- ventilatorassociated pneumonia patients (p=0.001. Higher age was detected in ventilator-associated pneumonia group (58±12.79 years and 51.37±15.87 years, p=0.001. Also hypertension and diabetes mellitus were observed more frequently (p=0.001. Development of enteral nutrition in patients with ventilator-associated pneumonia were significantly higher than those of parenterally fed patients (enteral: by 36.4% and 25.5% p=0.006; parenteral: 25% and 19.1%, p=0.042.

    This thesis presents a series of studies exploring the hypothesis that both ACE-inhibitors and statins, besides their intended effects, reduce the risk of acquiring pneumonia. Furthermore, as the burden of pneumonia is not only determined by its incidence but also by a high mortality, another widely

    Full Text Available Background: Childhood bacterial meningitis is a neurologic emergency that continues to kill and maims children particularly in developing countries with poor immunization coverage. Objective: This study set out to assess the hospital incidence, pattern of presentation, etiologic agents, outcome and determinants of mortality among the children admitted with bacterial meningitis at the Wesley Guild Hospital (WGH, Ilesa. Patients and Methods: We carried out a retrospective review of admitted cases of bacterial meningitis in children aged one month to 15 years at the WGH, Ilesa over a three year period by looking at the hospital records. Factors in the history and examinations were compared among survivors and those that died to determine factors significantly associated with mortality in these children. Results: Eighty-one (5.5% of the 1470 childhood admissions during the study period had bacterial meningitis. Male preponderance was observed and two-thirds of the children were infants. More cases were admitted during the wet rainy season than during the dry harmattan season. Haemophilus influenzae type B and Streptococcus pneumoniae were the leading etiologic agents and ciprofloxacin and ceftriaxone adequately cover for these organisms. Twenty-two (27.2% of the 81 children died, while 34 (42.0% survived with neurologic deficits. Children with multiple seizures, coma, neck retraction, hyponatremia, hypoglycorrhachia, turbid CSF as well as Gram positive meningitis at presentation were found to more likely to die (P < 0.05. None of these factors however independently predict mortality. Conclusion: Childhood bacterial meningitis often results in death and neurologic deficit among infants and young children admitted at the WGH, Ilesa. Children diagnosed with meningitis who in addition had multiple seizures, neck retraction and coma at presentation are at increased risk of dying.

    Background In Latin America, community-acquired pneumonia remains a major cause of morbidity and mortality among children. Few studies have examined the etiology of pneumonia in Ecuador. Methods This observational study was part of a randomized, double blind, placebo-controlled clinical trial conducted among children aged 2–59 months with severe pneumonia in Quito, Ecuador. Nasopharyngeal and blood samples were tested for bacterial and viral etiology by polymerase chain reaction. Risk factors for specific respiratory pathogens were also evaluated. Results Among 406 children tested, 159 (39.2%) had respiratory syncytial virus (RSV), 71 (17.5%) had human metapneumovirus (hMPV), and 62 (15.3%) had adenovirus. Streptococcus pneumoniae was identified in 37 (9.2%) samples and Mycoplasma pneumoniae in three (0.74%) samples. The yearly circulation pattern of RSV (P = 0.0003) overlapped with S. pneumoniae, (P = 0.03) with most cases occurring in the rainy season. In multivariable analysis, risk factors for RSV included younger age (adjusted odds ratio [aOR] = 1.9, P = 0.01) and being underweight (aOR = 1.8, P = 0.04). Maternal education (aOR = 0.82, P = 0.003), pulse oximetry (aOR = 0.93, P = 0.005), and rales (aOR = 0.25, P = 0.007) were associated with influenza A. Younger age (aOR = 3.5, P = 0.007) and elevated baseline respiratory rate were associated with HPIV-3 infection (aOR = 0.94, P = 0.03). Conclusion These results indicate the importance of RSV and influenza, and potentially modifiable risk factors including undernutrition and future use of a RSV vaccine, when an effective vaccine becomes available.

    Full Text Available Klebsiella peumoniae, a capsulated gram negative bacillus is responsible for causing life threatening infections in humans. Carbapenems are the drug of choice for serious infection caused by multidrug resistant Klebsiella pneumoniae. The emergence of carbapenem resistance has made it extremely difficult to treat such infections resulting in significant morbidity and mortality. Aims: To study the prevalence of carbapenem resistance using ertapenem as a marker and to detect Klebsiella pneumoniae Carbapenemase (KPC producing Klebsiella pneumoniae as a mechanism of resistance. Material and Methods: The study included 102 patients from which Klebsiella pneumoniae isolated. Identification and antibiotic susceptibility testing of Klebsiella pneumoniae was performed on miniAPI (Analytical Profile Index, Semiautomated bacterial identification system according to Clinical and Laboratory Standards Institute (CLSI guidelines of 2011. The modified Hodge test was performed for detection of Carbapenemase production. Patient’s clinical and demographic details along with risk factors and co-morbid conditions, type of response to antimicrobial therapy and mortality were collected. Results: The prevalence of carbapenem resistance was found to be 30.41% with 16.6% KPC producing Klebsiella pneumoniae. The co-morbid conditions like immunocompromised state (p =0.042, prior antibiotics therapy (p=0.047, previous hospitalization (p =0.021, intensive care unit stay (p=0.047 and use of indwelling devices (p =0.013 were found to be significantly associated with carbapenem resistance. Adverse clinical outcomes (death or worsening among patients infected with ertapenem resistant patients was found to be statistically significant than ertapenem sensitive strains (p =0.008. Conclusions: A high degree of carbapenem resistance in present study is alarming and poses therapeutic dilemmas for clinicians.

    In the developing world, vitamin A (VA) deficiency is endemic in populations that are also at great risk of morbidity and mortality because of pneumococcal pneumonia and enteric infections. To better understand how lung and gastrointestinal pathogens affect VA status, we assessed VA concentrations in serum, lung, and liver during an invasive pneumonia infection induced by Streptococcus pneumoniae serotype 3, and a noninvasive gut infection induced by Citrobacter rodentium, in vitamin A-adequate (VAA) and vitamin A-deficient (VAD) mice. For pneumonia infection, mice were immunized with pneumococcal polysaccharide serotype 3 (PPS3), or not (infected-control), 5 d prior to intranasal inoculation with S. pneumoniae. Two days post-inoculation, immunization was protective against systemic infection regardless of VA status as PPS3 immunization decreased bacteremia compared with infected-control mice (P pneumonia had less effect on VA status than gastrointestinal infection, predominantly owing to reduced hepatic VA storage at the peak of gut infection.

    Bronchiolitis is an acute lower respiratory tract infection in early childhood caused mainly by different viruses. Etiology of bronchiolitis have been studied in different environments and populations. Respiratory syncytial virus (RSV), human Metapneumovirus (hMPV), human Bocavirus (hBoV), human Rhinoviruses (hRV) have consistently been shown to predominate. Few studies however have attempted to determine whether other pathogens, particularly Mycoplasma Pneumoniae (MP) and Chlamydophila pneumoniae (CP), are associated with bronchiolitis in children under 2 years of age. The aim of this study was to determine the prevalence and clinical features of MP and CP in children under the age of 2 years presenting to the Iashvili Central Children Hospital in Tbilisi with various severities and clinical manifestations of bronchiolitis. Acute and convalescent serum samples were tested by ELISA for IgM and IgG antibodies to RSV, CP and MP.37 children under two years of age were studied. In 19 patients out of 37 (51.35%) etiological diagnosis were established and in 18 patients (48.65%) no pathogens were found. 11 patients (29.72%) had either CP or MP and 8 patients (21.62%) had RSV. Children infected with CP and MP had less severe bronchiolitis than those infected with RSV. Co-infection was not associated with disease severity. There were no statistically significant differences between groups with respect to length of hospital stay. Our study underlines the importance of atypical bacterial pathogens in acute bronchiolitis in children under 2 years and highlights the complex epidemiology and clinical features of these pathogens in this age group.

    New Delhi metallo-β-lactamase-1 (NDM-1)-producing Enterobacteriaceae have emerged as a global threat. The aim of this study was to assess the efficacies of colistin and tigecycline in an experimental model of pneumonia caused by NDM-1-producing Escherichia coli and Klebsiella pneumoniae. The susceptibilities of K. pneumoniae NDM, E. coli NDM and K. pneumoniae ATCC 29665 were determined using the broth microdilution technique. The pharmacokinetics of colistin and tigecycline in an experimental model of pneumonia were performed using immunocompetent C57BL/6 mice. Mice were treated with colistin (60 mg/kg/day) or tigecycline (10 mg/kg/day). Mortality, bacteraemia and lung bacterial concentrations were recorded. The strains were susceptible to colistin and tigecycline. The ratio of area under the concentration-time curve/minimum inhibitory concentration (AUC/MIC) for colistin was 158.5 (all three strains) and that for tigecycline was 18.5 (K. pneumoniae NDM) and 37 (K. pneumoniae ATCC 29665 and E. coli NDM). In vivo, colistin decreased bacterial lung concentrations of K. pneumoniae NDM and K. pneumoniae ATCC 29665 by 1.16 log colony-forming units (CFU)/g and 2.23 logCFU/g, respectively, compared with controls (not significant). Tigecycline reduced K. pneumoniae NDM and K. pneumoniae ATCC 29665 load by 2.67 logCFU/g and 4.62 logCFU/g (Ppneumonia due to NDM-1-producing K. pneumoniae and its efficacy was suboptimal against NDM-1-producing E. coli. A high tigecycline dose was efficacious for treating experimental pneumonia due to NDM-1-producing E. coli and K. pneumoniae.

    Globally, pneumonia is a serious public health concern and a major cause of mortality and morbidity. Despite advances in antimicrobial therapies, microbiological diagnostic tests and prevention measures, pneumonia remains the main cause of death from infectious disease in the world. An important reason for the increased global mortality is the impact of pneumonia on chronic diseases, along with the increasing age of the population and the virulence factors of the causative microorganism. The increasing number of multidrug-resistant bacteria, difficult-to-treat microorganisms, and the emergence of new pathogens are a major problem for clinicians when deciding antimicrobial therapy. A key factor for managing and effectively guiding appropriate antimicrobial therapy is an understanding of the role of the different causative microorganisms in the etiology of pneumonia, since it has been shown that the adequacy of initial antimicrobial therapy is a key factor for prognosis in pneumonia. Furthermore, broad-spectrum antibiotic therapies are sometimes given until microbiological results are available and de-escalation cannot be performed quickly. This review provides an overview of microbial etiology, resistance patterns, epidemiology and microbial diagnosis of pneumonia. PMID:27999274

    We investigated the clinical characteristics of patients with pneumonia caused by Aeromonas species. Patients with pneumonia caused by Aeromonas species during the period 2004 to 2011 were identified from a computerized database of a regional hospital in southern Taiwan. The medical records of these patients were retrospectively reviewed. Of the 84 patients with pneumonia due to Aeromonas species, possible Aeromonas pneumonia was diagnosed in 58 patients, probable Aeromonas pneumonia was diagnosed in 18 patients, and pneumonia due to Aeromonas was conclusively diagnosed in 8 patients. Most of the cases of Aeromonas pneumonia developed in men and in patients of advanced age. A. hydrophila (n = 50, 59.5 %) was the most common pathogen, followed by A. caviae (n = 24, 28.6 %), A. veronii biovar sobria (n = 7, 8.3 %), and A. veronii biovar veronii (n = 3, 3.6 %). Cancer (n = 37, 44.0 %) was the most common underlying disease, followed by diabetes mellitus (n = 27, 32.1 %). Drowning-associated pneumonia developed in 6 (7.1 %) patients. Of 47 patients who were admitted to the intensive care ward, 42 patients developed acute respiratory failure and 24 of those patients died. The overall in-hospital mortality rate was significantly associated with liver cirrhosis, cancer, initial presentation of shock, and usage of mechanical ventilation. In conclusion, Aeromonas species should be considered as one of the causative pathogens of severe pneumonia, especially in immunocompromised patients, and should be recognized as a cause of drowning-associated pneumonia. Cirrhosis, cancer, and shock as the initial presenting symptom are associated with poor outcome.

    Objective: In the antibiotic era, purulent pericarditis is a rare entity. However, there are still reports of cases of the disease, which is associated with high mortality, and most such cases are attributed to delayed diagnosis. Approximately 40-50% of all cases of purulent pericarditis are caused by Gram-positive bacteria, Streptococcus pneumoniae in particular. Methods: We report four cases of pneumococcal pneumonia complicated by pericarditis, with different clinical features and levels of severity. Results: In three of the four cases, the main complication was cardiac tamponade. Microbiological screening (urinary antigen testing and pleural fluid culture) confirmed the diagnosis of severe pneumococcal pneumonia complicated by purulent pericarditis. Conclusions: In cases of pneumococcal pneumonia complicated by pericarditis, early diagnosis is of paramount importance to avoid severe hemodynamic compromise. The complications of acute pericarditis appear early in the clinical course of the infection. The most serious complications are cardiac tamponade and its consequences. Antibiotic therapy combined with pericardiocentesis drastically reduces the mortality associated with purulent pericarditis. (author)

    Kentaro Isoda

    Full Text Available BACKGROUND: Acute/subacute interstitial pneumonia in dermatomyositis (DM-A/SIP is a disease associated with a poor prognosis that resists treatment with glucocorticosteroids (GC and progresses rapidly in a period of weeks to months to death. We retrospectively studied outcomes, prognostic factors, and their relations with survival rate in patients with DM-A/SIP treated with early cyclosporine A (CSA/GC combination therapy and 2-hour postdose blood concentration monitoring. METHODS: This study comprised 32 DM-A/SIP patients who were simultaneously treated with CSA and prednisolone. Clinical and laboratory findings were compared between those who died due to DM-A/SIP and those surviving 24 weeks after beginning of therapy. Prognostic factors were extracted, and their relations with the survival rate were evaluated. RESULTS: Of the 32 DM-A/SIP patients, 25 survived, 5 died of DM-A/SIP, and 2 died of infections. In those who died due to DM-A/SIP, ferritin level and the alveolar-arterial oxygen gradient were significantly increased compared with the survivors (P<0.001 and P = 0.002, respectively. Multivariate analyses showed that ferritin and alveolar-arterial oxygen gradient were independent prognostic factors of poor outcome. The survival rate 24 weeks after beginning of treatment was significantly lower in those with a ferritin level of ≥ 600 ng/ml and alveolar-arterial oxygen gradient of ≥ 45 Torr (P<0.001 and P<0.001, respectively. All patients with both prognostic factors died, and the outcome was significantly poorer in these patients than in those with one or neither of the prognostic factors (P<0.001. CONCLUSIONS: We identified pre-treatment high serum ferritin level and high alveolar-arterial oxygen gradient as poor prognostic factors in DM-A/SIP patients undergoing early CSA/GC combination therapy and showed that the outcomes were poor in patients with both factors.

    Full Text Available : BACKGROUND: Most of the times, a Community Acquired Pneumonia (CAP patient is being treated with empirical antibiotics by best guess method by the clinician. Patient who did not show expected clinical improvement or resolution on chest x- ray after 2 weeks of antibiotics is considered as unresolved or non-resolving pneumonia and is a major problem, contributing to increased mortality and morbidity in the medical wards. AIM OF STUDY: 1.Tostudy the clinical profile of unresolved pneumonia among CAP. 2. To know the treatment outcome in these cases. MATERIALS & METHODS: 80 hospitalized CAP patients who did not improve either clinically or radiologically after 2 weeks of broad spectrum antibiotics were included in the study. Details of these patients including investigations done at other higher centers were recorded and patients were followed up for 6 months or till death. RESULTS: Unresolved pneumonia was commonly observed in patients more than 50 years. Pulmonary tuberculosis was the commonest cause, followed by MDR varieties of CAP, Bronchogenic carcinoma. Multiple risk factors were noted, which includes cigarette smoking, alcohol, COPD, Diabetes, HIV positive status. Elderly age, multiple risk factors, antibiotic abuse and resistance resulted in majority of the cases. CONCLUSION: This study highlights the importance of early recognition and appropriate treatment of CAP to prevent unresolved pneumonia and use of invasive and latest investigations to recognize unresolved pneumonia, to decrease mortality and morbidity.

    Bacterial pneumonia is a major cause of morbidity and mortality in elderly. We hypothesize that dysbiosis between regular residents of the upper respiratory tract (URT) microbiome, that is balance between commensals and potential pathogens, is involved in pathogen overgrowth and consequently disease. We compared oropharyngeal microbiota of elderly pneumonia patients (n=100) with healthy elderly (n=91) by 16S-rRNA-based sequencing and verified our findings in young adult pneumonia patients (n=27) and young healthy adults (n=187). Microbiota profiles differed significantly between elderly pneumonia patients and healthy elderly (PERMANOVA, Pdisease was less clear. A decision tree model based on the relative abundance of five bacterial community members in URT microbiota showed high specificity of 95% and sensitivity of 84% (89% and 73%, respectively, after cross-validation) for differentiating pneumonia patients from healthy individuals. These results suggest that pneumonia in elderly and young adults is associated with dysbiosis of the URT microbiome with bacterial overgrowth of single species and absence of distinct anaerobic bacteria. Whether the observed microbiome changes are a cause or a consequence of the development of pneumonia or merely coincide with disease status remains a question for future research.

    Nosocomial pneumonia is a major cause of morbidity and mortality in hospitalized patients. The risk is especially high in the neonatal intensive care unit (NICU) particularly in infants with mechanically assisted ventilation. During the 5-year period of the study, 160 infants with problems including prematurity (60.6%), respiratory distress (55.6%) and birth asphyxia (45.0%) were admitted to the NICU. One hundred and thirty-three infants (83.1%) received mechanical ventilation. Nosocomial pneumonia was found in 65 infants (40.6%) or 88.3 cases per 1,000 ventilator-days. Low birth weight, prematurity, respiratory distress and hyperbilirubinemia were found more significantly in the pneumonia group. They underwent more manipulations such as the placement of an umbilical catheter and orogastric tube. Infants with pneumonia received mechanical ventilation at a higher percentage and for a longer period than those without pneumonia (96.9% vs 73.7%, odds ratio = 11.2, p = 0.000) with a mean duration of 11.7 and 3.5 days respectively (p = 0.000). The etiologic organisms recovered from hemoculture were Acinetobacter calcoaceticus var. anitratus 44.0 per cent, Enterobacter spp. 16.0 per cent, Klebsiella pneumoniae 16.0 per cent, coagulase-negative staphylococci 12.0 per cent. There was no concordance of the bacteriologic results in endotracheal aspirate culture and hemoculture in each infant. Leukocytosis and granulocytosis as well as blood gas values could not differentiate the presence of pneumonia. The mean hospital stay for the infants with pneumonia was longer (23.0 days vs 6.4 days, p = 0.000). Nosocomial pneumonia did not only prolong hospital stay but also contributed to mortality. Twenty-seven (41.5%) of the infants with pneumonia died, compared with 46 (48.4%) of the other group without pneumonia (p = 0.422). The risk of nosocomial pneumonia can be reduced by using infection control measures, including meticulous hand washing and gloving during respiratory

    AP is a major cause of morbidity and mortality in elderly patients, especially frail elderly patients. The aim of this article is to review effect of oral care, including oral hygiene and improvement of oral function, on the prevention of AP among elderly people in hospitals and nursing homes. There is now a substantial body of work studying the effect of oral care on the prevention of respiratory diseases. Oral hygiene, consisting of oral decontamination and mechanical cleaning by dental professionals, has resulted in significant clinical effects (decreased incidence of pneumonia and decreased mortality from respiratory diseases) in clinical randomized trials. Moreover, studies examining oral colonization by pneumonia pathogens have shown the effect of oral hygiene on eliminating these pathogens. In addition, swallowing training has been shown to improve the movement and function of swallowing-related muscles, also resulting in decreased incidence of pneumonia. These findings support the contention that oral care is effective in the prevention of AP.

    Full Text Available Introduction. Pneumonia is the most frequent nosocomial infection in intensive care units. The reported frequency varies with definition, the type of hospital or intensive care units and the population of patients. The incidence ranges from 6.8-27%. Objective. The objective of this study was to determine the frequency, risk factors and mortality of nosocomial pneumonia in intensive care patients. Methods. We analyzed retrospectively and prospectively the collected data of 180 patients with central nervous system infections who needed to stay in the intensive care unit for more than 48 hours. This study was conducted from 2003 to 2009 at the Clinical Centre of Kragujevac. Results. During the study period, 54 (30% patients developed nosocomial pneumonia. The time to develop pneumonia was 10±6 days. We found that the following risk factors for the development of nosocomial pneumonia were statistically significant: age, Glasgow Coma Scale (GCS score <9, mechanical ventilation, duration of mechanical ventilation, tracheostomy, presence of nasogastric tube and enteral feeding. The most commonly isolated pathogens were Klebsiella-Enterobacter spp. (33.3%, Pseudomonas aeruginosa (24.1%, Acinetobacter spp. (16.6% and Staphylococcus aureus (25.9%. Conclusion. Nosocomial pneumonia is the major cause of morbidity and mortality of patients with central nervous system infections. Patients on mechanical ventilation are particularly at a high risk. The mortality rate of patients with nosocomial pneumonia was 54.4% and it was five times higher than in patients without pneumonia.

    Full Text Available Pneumonia is a frequent cause of hospital admission in elderly patients. Diagnosis of pneumonia in elderly persons with comorbidity may be challenging, due to atypical presentation and complex clinical scenarios. Community-acquired pneumonia (CAP arises out-of-hospital in subjects without previous contact with the healthcare system. Healthcare associated pneumonia (HCAP occurs in patients who have frequent contacts with the healthcare system and should be treated with empiric broad spectrum antibiotic therapy also covering multi-drug resistant (MDR pathogens. Recent findings, however, have questioned this approach, because the worse prognosis of HCAP compared to CAP may better reflect increased level of comorbidity and frailty (poor functional status, older age of HCAP patients, as well as poorer quality of hospital care provided to such patients, rather than pneumonia etiology by MDR pathogens. The Pneumonia in Italian Acute Care for Elderly units (PIACE Study, promoted by the Società Italiana di Geriatria Ospedale e Territorio (SIGOT, is an observational prospective cohort study of patients consecutively admitted because of pneumonia to hospital acute care units of Geriatrics throughout Italy. Detailed information regarding clinical presentation, diagnosis, etiology, comprehensive geriatric assessment, antibiotic therapy, possible complications and comorbidities was recorded to identify factors potentially predicting in-hospital mortality (primary endpoint, 3-month mortality, length of hospital stay, postdischarge rate of institutionalization and other secondary endpoints. This paper describes the rationale and method of PIACE Study and reviews the main evidence on pneumonia in the elderly.

  13. Carriage of Streptococcus pneumoniae and other respiratory bacterial pathogens in low and lower-middle income countries: a systematic review and meta-analysis.

    Directory of Open Access Journals (Sweden)

    Richard A Adegbola

    Full Text Available BACKGROUND: Infection with Streptococcus pneumoniae is a major cause of childhood morbidity and mortality worldwide, especially in low income countries where pneumococcal conjugate vaccines (PCVs are still underused. In countries where PCVs have been introduced, much of their efficacy has resulted from their impact on nasopharyngeal carriage in vaccinated children. Understanding the epidemiology of carriage for S. pneumoniae and other common respiratory bacteria in developing countries is crucial for implementing appropriate vaccination strategies and evaluating their impact. METHODS AND FINDINGS: We have systematically reviewed published studies reporting nasopharyngeal or oropharyngeal carriage of S. pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus, and Neisseria meningitidis in children and adults in low and lower-middle income countries. Studies reporting pneumococcal carriage for healthy children <5 years of age were selected for a meta-analysis. The prevalences of carriage for S. pneumoniae, H. influenzae, and M. catarrhalis were generally higher in low income than in lower-middle income countries and were higher in young children than in adults. The prevalence of S. aureus was high in neonates. Meta-analysis of data from young children before the introduction of PCVs showed a pooled prevalence estimate of 64.8% (95% confidence interval, 49.8%-76.1% in low income countries and 47.8% (95% confidence interval, 44.7%-50.8% in lower-middle income countries. The most frequent serotypes were 6A, 6B, 19A, 19F, and 23F. CONCLUSIONS: In low and lower-middle income countries, pneumococcal carriage is frequent, especially in children, and the spectrum of serotypes is wide. However, because data are limited, additional studies are needed to adequately assess the impact of PCV introduction on carriage of respiratory bacteria in these countries.

This paper explores the definitions and concepts...... and poor treatment results using antibiotics. Moreover, children diagnosed with recurrent pneumonia in infancy were often later diagnosed with asthma.

Ultimately, underlying asthma may have contributed to malnutrition and fatal bacterial pneumonia. In conclusion, preschool asthma in low-income countries may be significantly under...

  15. Measuring coverage in MNCH: challenges in monitoring the proportion of young children with pneumonia who receive antibiotic treatment.

    Directory of Open Access Journals (Sweden)

    Harry Campbell

    Full Text Available Pneumonia remains a major cause of child death globally, and improving antibiotic treatment rates is a key control strategy. Progress in improving the global coverage of antibiotic treatment is monitored through large household surveys such as the Demographic and Health Surveys (DHS and the Multiple Indicator Cluster Surveys (MICS, which estimate antibiotic treatment rates of pneumonia based on two-week recall of pneumonia by caregivers. However, these survey tools identify children with reported symptoms of pneumonia, and because the prevalence of pneumonia over a two-week period in community settings is low, the majority of these children do not have true pneumonia and so do not provide an accurate denominator of pneumonia cases for monitoring antibiotic treatment rates. In this review, we show that the performance of survey tools could be improved by increasing the survey recall period or by improving either overall discriminative power or specificity. However, even at a test specificity of 95% (and a test sensitivity of 80%, the proportion of children with reported symptoms of pneumonia who truly have pneumonia is only 22% (the positive predictive value of the survey tool. Thus, although DHS and MICS survey data on rates of care seeking for children with reported symptoms of pneumonia and other childhood illnesses remain valid and important, DHS and MICS data are not able to give valid estimates of antibiotic treatment rates in children with pneumonia.

    Full Text Available Background: Few investigation has focused on the patients with lupus nephritis (LN and neuropsychiatric systemic lupus erythematosus (NPSLE. This study was aimed to investigate the clinical features, mortality, and the predictors for mortality of this group of patients. Materials and Methods: Medical records were retrospectively reviewed in Sun Yat-sen Memorial Hospital from 1996 to 2012. Data of demographic information, clinical manifestations, laboratory tests, SLE disease activity index 2000 (SLEDAI-2K score, diagnosis, complications, treatment, and mortality was collected. Results: A total of 124 patients were included in our study. Thirty-five (29.1% patients had glomerular filtration rate <60 ml/min/1.73 m 2 , while 24 (19.4% experienced acute kidney injury (AKI. Thirteen of the 19 American College of Rheumatology defined NPSLE syndromes were identified. The most frequent manifestation was seizure disorder (56/124, 45.2%, followed by psychosis (37/124, 29.8% and cerebrovascular disease (35/124, 28.2%. One hundred and five (84.7% patients had SLEDAI-2K scores ≥15, the mean of which was 21.5 ± 6.2. The mortality during hospitalization was 12.9% (16/124 with NP involvement itself being the leading cause of death (7/16, 43.8%. Multivariate logistic regression confirmed that age <14 years at onset of NPSLE (odds ratios [OR]: 9.95, 95% confidence intervals [CI]: 1.43-69.36, P = 0.020, AKI (OR: 10.40, 95% CI: 2.33-46.48, P = 0.002 and pneumonia (OR: 4.52, 95% CI: 1.14-17.96, P = 0.032 were risk factors for mortality, while cyclophosphamide (CYC treatment (OR: 0.09, 95% CI: 0.02-0.54, P = 0.008 was a protective factor. Conclusion: Most of SLE patients with LN and new-onset NPSLE are in an active disease state. NP manifestation itself was the leading cause of death during hospitalization. Childhood-onset NPSLE, AKI and pneumonia might be predictors of mortality, whereas CYC treatment might improve the prognosis.

    Purpose Patients with nursing home-acquired pneumonia (NHAP) should be treated as hospital-acquired pneumonia (HAP) according to guidelines published in 2005. However, controversy still exists on whether the high mortality of NHAP results from multidrug resistant pathogens or underlying disease. We aimed to outline differences and factors contributing to mortality between NHAP and community-acquired pneumonia (CAP) patients. Materials and Methods We retrospectively evaluated patients aged 65 years or older with either CAP or NHAP from 2008 to 2014. Patients with healthcare-associated pneumonia other than NHAP or HAP were excluded. Results Among 317 patients, 212 patients had CAP and 105 had NHAP. Patients with NHAP had higher mortality, more frequently used a ventilator, and had disease of higher severity than CAP. The incidences of aspiration, tube feeding, and poor functional status were higher in NHAP. Twenty three out of 54 NHAP patients and three out of 62 CAP patients had multidrug resistant pathogens (p<0.001). Eleven patients with NHAP died at discharge, compared to 7 patients with CAP (p=0.009). However, there was no association between mortality rate and presence of multidrug-resistant pathogens. The number of involved lobes on chest X-ray [odds ratio (OR)=1.708; 95% confidence interval (CI), 1.120 to 2.605] and use of mechanical ventilation (OR=9.537; 95% CI, 1.635 to 55.632) were significantly associated with in-hospital mortality. Conclusion Patients with NHAP had higher mortality than patients with CAP. The excess mortality among patients with NHAP and CAP was related to disease severity but not to the presence of multidrug resistant pathogens. PMID:27873512

    Meningitis is one of the hazardous and life threatening infections and is associated with mortality and morbidity. The aim of this study was to determine etiological agents of childhood bacterial meningitis. The culture, Gram staining, agglutination and PCR assays were used to examine CSF specimens from 277 patients with presumed bacterial meningitis for the occurrence of 4 most common infectious agents consist of N. meningitis, H. influnsae, S. pneumoniae and S. agalactiae between 2008 and 2009 at different wards of the Children Hospital of Tabriz. The mean age of patients was 35 ± 2 (Mean ± SEM) month, (minimum 11 days maximum 14 years), of all cases 59.6% male and 40.4% female. Overall the diagnosis was confirmed with a CSF culture in 11/277 (3.97%), by agglutination test in 14/277 (5.05%). The isolated bacteria included S. pneumoniae 5 cases, H. influnsae 2 cases, N. meningitis 3 cases and P. aeroginusae 1 case. A positive PCR assay allowed us to diagnose bacterial meningitis in 19 patients (6.8%). In the present study, we found PCR to be a useful and sensitive method for the detection of bacterial DNA in the CSF samples from suspected meningitis patients. Furthermore, to maximize management of meningitis cases, a combination of culture and PCR is necessary.

    Full Text Available Historically, atypical pneumonia was a term used to describe an unusual presentation of pneumonia. Currently, it is used to describe the multitude of symptoms juxtaposing the classic symptoms found in cases of pneumococcal pneumonia. Specifically, atypical pneumonia is a syndrome resulting from a relatively common group of pathogens including Chlamydophila sp., and Mycoplasma pneumoniae. The incidence of M. pneumoniae pneumonia in adults is less than the burden experienced by children. Transmission rates among families indicate children may act as a reservoir and maintain contagiousness over a long period of time ranging from months to years. In adults, M. pneumoniae typically produces a mild, walking pneumonia and is considered to be one of the causes of persistent cough in patients. M. pneumoniae has also been shown to trigger the exacerbation of other lung diseases. It has been repeatedly detected in patients with bronchitis, asthma, chronic obstructive pulmonary disorder and cystic fibrosis. Recent advances in technology allow for the rapid diagnosis of M. pneumoniae through the use of polymerase chain reaction (PCR or rapid antigen tests. With this, more effort has been afforded to identify the causative etiologic agent in all cases of pneumonia. However, previous practices, including the overprescribing of macrolide treatment in China and Japan, have created increased incidence of macrolide-resistant M. pneumoniae. Reports from these countries indicate that >85% of M. pneumoniae pneumonia pediatric cases are macrolide-resistant. Despite its extensively studied past, the smallest bacterial species still inspires some of the largest questions. The developments in microbiology, diagnostic features and techniques, epidemiology, treatment and vaccines, and upper respiratory conditions associated with M. pneumoniae in adult populations are included within this review.

    Community acquired pneumonia (CAP) is an acute respiratory infection that affects pulmonary parenchyma, and is caused by community acquired microorganisms. In Chile, pneumonia represents the main cause of death due to infectious diseases and is the third specific cause of mortality in adults. In 1999, an experts committee in representation of "Sociedad Chilena de Enfermedades Respiratorias", presented the first National Guidelines for the Treatment of Adult Community Acquired Pneumonia, mainly based in foreign experience and documents, and adapted it to our National Health System Organization. During the last decade, impressive epidemiological and technological changes have occurred, making the update of guidelines for treatment of NAC by several international scientific societies, necessary. These changes include: new respiratory pathogens that are being identified in CAP and affect adult patients (Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella pneumophila); the increasing senescent adult population that carries multiple co-morbidities; the emergence of antimicrobial resistance among respiratory pathogens associated to massive antibiotic prescription; the development by the pharmaceutical industry of new drugs that are effective for pneumonia treatment (macrolides, ketolides and respiratory fluorquinolones); and the development of new diagnostic techniques for detection of antigens, antibodies, and bacterial DNA by molecular biology, useful in respiratory infections. Based on these antecedents, an Advisory Committee of "Sociedad Chilena de Enfermedades Respiratorias" and "Sociedad Chilena de Infectología" has reviewed the national and international evidence about CAP management in adults in order to update clinical recommendations for our country.

    Full Text Available Introduction: Streptococcus pneumoniae cause morbidity and mortality in infants and younger children.   Because of high prevalence of penicillin  resistance, rapid  and  reliable diagnostic techniques for penicillin non-susceptible S. pneumoniae (PNSSP are important for prevention and treatment. We investigated the association of the restriction length polymorphism (RFLP patterns for pbp2b to distinguish between penicillin susceptible and resistant S. pneumoniae isolates.Methods: In this study, a total of 70 pneumococcal isolates were collected from different clinical sources. MIC of these isolates was determined and pbp2b gene was amplified by PCR and they were digested by HaeІІІ enzyme.Results: Of the 70 isolates, 86% (60 and 14% (10 pneumococcal isolates were found to be PNSSP (penicillin intermediate S. pneumoniae (PISP and penicillin resistant S. pneumoniae (PRSP and penicillin susceptible S. pneumoniae (PSSP. In addition, 10 RFLP patterns (A-J which were based on the HaeІІІ digestion of pbp2b gene were observed. All PSSP isolates showed that they belonged to pattern D, whereas, all PNSSP showed 10 different patterns.Conclusion:  In  general,  the  present  study  suggests  that  RFLP  can  be  a  powerful  tool  in differentiation between the penicillin resistant and susceptible strains.

    Full Text Available BACKGROUND: MRSA remains a leading cause of hospital-acquired (HAP and healthcare-associated pneumonia (HCAP. We describe the epidemiology and outcome of MRSA pneumonia in Canadian hospitals, and identify factors contributing to mortality. METHODS: Prospective surveillance for MRSA pneumonia in adults was done for one year (2011 in 11 Canadian hospitals. Standard criteria for MRSA HAP, HCAP, ventilator-associated pneumonia (VAP, and community-acquired pneumonia (CAP were used to identify cases. MRSA isolates underwent antimicrobial susceptibility testing, and were characterized by pulsed-field gel electrophoresis (PFGE and Panton-Valentine leukocidin (PVL gene detection. The primary outcome was all-cause mortality at 30 days. A multivariable analysis was done to examine the association between various host and microbial factors and mortality. RESULTS: A total of 161 patients with MRSA pneumonia were identified: 90 (56% with HAP, 26 (16% HCAP, and 45 (28% CAP; 23 (14% patients had VAP. The mean (± SD incidence of MRSA HAP was 0.32 (± 0.26 per 10,000 patient-days, and of MRSA VAP was 0.30 (± 0.5 per 1,000 ventilator-days. The 30-day all-cause mortality was 28.0%. In multivariable analysis, variables associated with mortality were the presence of multiorgan failure (OR 8.1; 95% CI 2.5-26.0, and infection with an isolate with reduced susceptibility to vancomycin (OR 2.5, 95% CI 1.0-6.3. CONCLUSIONS: MRSA pneumonia is associated with significant mortality. Severity of disease at presentation, and infection caused by an isolate with elevated MIC to vancomcyin are associated with increased mortality. Additional studies are required to better understand the impact of host and microbial variables on outcome.

    Nursing- and healthcare-associated pneumonia (NHCAP) has been proposed by the Japanese Respiratory Society as a new category of pneumonia considering the characteristics of the Japanese medical care environment. It is necessary to ascertain the epidemiology and clinical outcomes of NHCAP. A prospective study was conducted of patients with pneumonia who were hospitalized at our hospital from August 2011 to July 2012. We compared 192 cases of NHCAP with 114 cases of community-acquired pneumonia (CAP). Compared with CAP, NHCAP had a higher disease severity, higher 30-day mortality rate (10.9 vs. 3.5 %, P = 0.022), and longer length of hospital stay (median, 12 vs. 8 days, P pneumoniae was the most frequent causative pathogen in both NHCAP and CAP (33.9 vs. 34.8 %, P = 0.896). The incidence of atypical pathogens in NHCAP was low (1.7 %). Multidrug-resistant (MDR) pathogens were isolated more frequently in NHCAP than in CAP, but there was no significant difference (11.0 vs. 4.5 %, P = 0.135). Among 192 NHCAP patients, 122 (63.5 %) were aspiration pneumonia. Aspiration pneumonia was associated with poor outcomes and was considered a major characteristic of NHCAP. Our study suggested that many patients with NHCAP do not need broad-spectrum antibiotic therapy targeting MDR pathogens. Excess mortality in NHCAP patients is the result of patient backgrounds or disease severity rather than the presence of MDR pathogens.

    Wildlife mortality events usually occur unannounced and may find management agencies unaware. These events can become highly visible and politically charged affairs, depending upon the scale or species involved. The public, media, and (or) politicians may pressure managers, field investigators, and diagnosticians to quickly identify the cause or to comment on potential causes, the significance of the event, what is being done about it, and a resolution. It may be common during such events for speculation to rage, and for conflicting theories to be advanced to explain either the environmental conditions that led to the mortality or the actual cause of death.

    Pneumonia is the most common complication observed in patients with severe injuries. Although the average age of injured patients is 47 years, existing studies of the effect of injury on the susceptibility to infectious complications have focused on young animals, equivalent to a late adolescent human. We hypothesized that mature adult animals are more susceptible to infection after injury than younger counterparts. To test this hypothesis, we challenged 6 to 8-month-old mature mice to a polytrauma injury followed by Pseudomonas aeruginosa pneumonia and compared them to young (8-10-week-old) animals. We demonstrate that polytrauma injury increases mortality from pneumonia in mature animals (sham-pneumonia 21% vs. polytrauma-pneumonia 62%) but not younger counterparts. After polytrauma, pneumonia in mature mice is associated with higher bacterial burden in lung, increased incidence of bacteremia, and elevated levels of bacteria in the blood, demonstrating that injury decreases the ability to control the infectious challenge. We further find that polytrauma did not induce elevations in circulating cytokine levels (TNF-alpha, IL-6, KC, and IL-10) 24  h after injury. However, mature mice subjected to polytrauma demonstrated an exaggerated circulating inflammatory cytokine response to subsequent Pseudomonas pneumonia. Additionally, whereas prior injury increases LPS-stimulated IL-6 production by peripheral blood leukocytes from young (8-10-week-old) mice, injury does not prime IL-6 production by cell from mature adult mice. We conclude that in mature mice polytrauma results in increased susceptibility to Pseudomonas pneumonia while priming an exaggerated but ineffective inflammatory response.

    Streptococcus pneumoniae is the leading cause of bacterial pneumonia, meningitis and sepsis in children worldwide. Despite available evidence on pneumococcal conjugate vaccine (PCV) impact on pneumonia hospitalizations in children, studies demonstrating PCV impact in morbidity and mortality in middle-income countries are still scarce. Given the disease burden, PCV7 was introduced in Peru in 2009, and then switched to PCV10 in late 2011. National public healthcare system provides care for 60% of the population, and national hospitalization, outpatient and mortality data are available. We thus aimed to assess the effects of routine PCV vaccination on pneumonia hospitalization and mortality, and acute otitis media (AOM) and all cause pneumonia outpatient visits in children under one year of age in Peru. We conducted a segmented time-series analysis using outcome-specific regression models. Study period was from January 2006 to December 2012. Data sources included the National information systems for hospitalization, mortality, outpatient visits, and RENACE, the national database of aggregated weekly notifications of pneumonia and other acute respiratory diseases (both hospitalized and non-hospitalized). Study outcomes included community acquired pneumonia outpatient visits, hospitalizations and deaths (ICD10 codes J12-J18); and AOM outpatient visits (H65-H67). Monthly age- and sex-specific admission, outpatient visit, and mortality rates per 100,000 children aged impact in morbidity and mortality in children aged <1year. Vaccine effectiveness was 26.2% (95% CI 16.9-34.4) for AOM visits, 35% (95% CI 8.6-53.8) for mortality due to pneumonia, and 20.6% (95% CI 10.6-29.5) for weekly cases of pneumonia hospitalization and outpatient visits notified to RENACE. We used secondary data sources which are usually developed for other non-epidemiologic purposes. Despite some data limitations, our results clearly demonstrate the overall benefit of PCV vaccination in Peru.

    Background: Gram negative bacteria along with Pseudomonas constitute a significant cause of morbidity and mortality due to pneumonia. As a result it is essential to have appropriate empirical antimicrobial treatment strategies based on the sensitivity pattern of a particular region. In cases with high likelihood of gram negative pneumonia it is essential to start appropriate empirical antibiotics as early as possible to reduce the morbidity and mortality. This study is done to know the antibi...

  15. Island mortality in the past: some evidence from Greece.

    2008-03-01

    This paper explores the course of infant and childhood mortality in the Greek island of Paros from the end of the nineteenth until the mid-twentieth century. For this purpose the method of family reconstitution has been applied to two towns on the island. Official population statistics have been used to derive basic mortality estimates for the Cyclades and Greece as a whole. Reference to other studies concerning island mortality is also made. Hence, there appears the chance to compare insular with mainland mortality and realise that insular mortality presented some distinct features. It is shown that island populations presented lower mortality than the national average until the first decades of the twentieth century. However, by the 1950s Greece's infant and childhood mortality had dropped to the same or even to lower levels than those of the islands.

    Full Text Available Abstract Ventilator associated pneumonia (VAP is the leading cause of morbidity and mortality in intensive care units. The incidence of VAP varies from 7% to 70% in different studies and the mortality rates are 20–75% according to the study population. Aspiration of colonized pathogenic microorganisms on the oropharynx and gastrointestinal tract is the main route for the development of VAP. On the other hand, the major risk factor for VAP is intubation and the duration of mechanical ventilation. Diagnosis remains difficult, and studies showed the importance of early initiation of appropriate antibiotic for prognosis. VAP causes extra length of stay in hospital and intensive care units and increases hospital cost. Consequently, infection control policies are more rational and will save money.

    Full Text Available Streptococcus pneumoniae is a leading cause of pneumonia worldwide. However, the burden of pneumococcal pneumonia among adults in low- and middle-income countries is not well described.Data from 2008-2012 was analyzed from two surveillance sites in Guatemala to describe the incidence of pneumococcal pneumonia in adults. A case of hospitalized pneumococcal pneumonia was defined as a positive pneumococcal urinary antigen test or blood culture in persons aged ≥ 18 years hospitalized with an acute respiratory infection (ARI.Among 1595 adults admitted with ARI, 1363 (82% had either urine testing (n = 1286 or blood culture (n = 338 performed. Of these, 188 (14% had pneumococcal pneumonia, including 173 detected by urine only, 8 by blood culture only, and 7 by both methods. Incidence rates increased with age, with the lowest rate among 18-24 year-olds (2.75/100,000 and the highest among ≥65 year-olds (31.3/100,000. The adjusted incidence of hospitalized pneumococcal pneumonia was 18.6/100,000 overall, with in-hospital mortality of 5%.An important burden of hospitalized pneumococcal pneumonia in adults was described, particularly for the elderly. However, even adjusted rates likely underestimate the true burden of pneumococcal pneumonia in the community. These data provide a baseline against which to measure the indirect effects of the 2013 introduction of the pneumococcal conjugate vaccine in children in Guatemala.

In this study, the factors of VAP developing in patients whom the mechanical ventilation of ICU performed, antibiotic susceptibility to these factors and determining the risk factors were aimed. Material and Method: Between January 2009 and March 2013, 79 cases, followed with the mechanical ventilation for at least for 48 hours and developed VAP, were retrospectively reviewed at Anesthesiology and Intensive Care Unit of Reanimation at Faculty of Medicine at Yuzuncu Yil University, performing endotracheal intubation. The cases were evaluated in terms of microorganisms, antibiotic susceptibility and risk factors. Results: The rate of our VAP speed was calculated to be 19.68 on the day of 1000 ventilator. While a single microorganism could be isolated in 81.1% of the 74 VAP cases whose the active pathogen could be isolated, two or more than two microorganisms were isolated in 18.9% of them.While 83 of the strains (90.2% were gram-negative bacteria, 7 of them (7.6% were gram-positive bacteria. Acinetobacter spp. (40.2% was most commonly isolated as a gram-negative factor, but methicillin-resistant S. aureus (4.3% was isolated as a gram-positive factor. It was determined that the isolated factors in VAP cases were significantly resistant to the broad-spectrum antibiotics. Discussion: As a result, in patients with high-risk factors for the development of VAP, early and appropriate empirical antibiotic treatment should be started according to the results of the sensitivity of the unit and for the multi-drug-resistant microorganisms with common and high mortality.

    2013-04-01

    Childhood obesity is an issue of serious medical and social concern. In developing countries including India, it is a phenomenon seen in higher socioeconomic strata due to the adoption of a western lifestyle. Consumption of high calorie food, lack of physical activity and increased screen time are major risk factors for childhood obesity apart from other genetic, prenatal factors and socio-cultural practices. Obese children and adolescents are at increased risk of medical and psychological complications. Insulin resistance is commonly present especially in those with central obesity and manifests as dyslipidemia, type 2 diabetes mellitus, impaired glucose tolerance, hypertension, polycystic ovarian syndrome and metabolic syndrome. Obese children and adolescents often present to general physicians for management. The latter play a key role in prevention and treatment of obesity as it involves lifestyle modification of the entire family. This article aims at discussing the approach to diagnosis and work-up, treatment and preventive strategies for childhood obesity from a general physician's perspective.

    INTRODUCTION: Nosocomial pneumonia in relation to tracheotomy is a well-known complication. The aim of the present study was to study prophylactic antibiotics at the time of tracheotomy as a protective factor against nosocomial pneumonia. METHODS: A retrospective follow-up study was conducted...... for inclusion, forming a group without antibiotics (n = 53) treatment and a group with antibiotics (n = 35) treatment. RESULTS: In the group without antibiotics, 67% (n = 34) developed pneumonia (not including aspirational) versus 44% (n = 14) in the group with antibiotics (p = 0.04). The 30-day mortality...... was 10% (n = 9), and the one-year mortality was 58% (n = 42) for the total population, with no statistically significant differences between the groups. Pneumonia after tracheotomy prolonged the hospitalisation time regardless of grouping. In the group without antibiotics, the median was seven days...

    Pneumonia is a common and potentially serious infectious disease. Morbidity and mortality rates continue to be high in spite of major advances and steady progress in diagnosis and treatment. The economic impact of the disease is also great. It is therefore necessary to enlist the public, primary care and emergency physicians, and public policy administrators to join forces to treat and prevent pneumonia for the common good. The annual incidence of pneumonia in the population over the age of 14 years is 1.6 to 2.6 episodes/1000 inhabitants. The mortality rate is 14.1 per 100,000 inhabitants, and the associated costs are 115 million euros annually. The RESPIRA Foundation and the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) declared 2004 to be pneumonia awareness year with the aim of coordinating efforts to raise awareness, distribute information, and foster debate.

    2016-02-01

    Full Text Available Hospital-acquired pneumonia (HAP is a frequent cause of nosocomial infections, responsible for great morbidity and mortality worldwide. The majority of studies on HAP have been conducted in patients hospitalized in the intensive care unit (ICU, as mechanical ventilation represents a major risk factor for nosocomial pneumonia and specifically for ventilator-associated pneumonia. However, epidemiological data seem to be different between patients acquiring HAP in the ICU vs. general wards, suggesting the importance of identifying non ICU-acquired pneumonia (NIAP as a clinical distinct entity in terms of both etiology and management. Early detection of NIAP, along with an individualized management, is needed to reduce antibiotic use and side effects, bacterial resistance and mortality. The present article reviews the pathophysiology, diagnosis, treatment and prevention of NIAP.

    Community-acquired pneumonia (CAP) is an important cause of mortality and morbidity amongst adults in the Asia-Pacific region. Literature published between 1990 and May 2010 on the clinical and economic burden of CAP amongst adults in this region was reviewed. CAP is a significant health burden with significant economic impact in this region. Chronic obstructive pulmonary disease, cardiovascular disease, diabetes mellitus and advanced age were risk factors for CAP. Aetiological agents included Streptococcus pneumoniae, Klebsiella pneumoniae, Gram-negative bacteria, Mycobacterium tuberculosis, Burkholderia pseudomallei, Staphylococcus aureus and atypical pathogens (Mycoplasma pneumoniae, Chlamydophila pneumoniae and Legionella spp.), with important differences in the prevalence of these pathogens within the region. Antibiotic resistance was significant but was not linked to excess mortality. Aetiological pathogens remained susceptible to newer antimicrobial agents. Rational antibiotic use is essential for preventing resistance, and increased surveillance is required to identify future trends in incidence and aetiology and to drive treatment and prevention strategies.

    Corticosteroids are frequently prescribed anti-inflammatory medications. Inhaled corticosteroids (ICS) are indicated for Chronic Obstructive Pulmonary Disease (COPD) and asthma. ICS are associated with a decrease in exacerbations and improved quality of life in COPD, however multiple studies have linked the chronic use of ICSs with an increased risk of developing pneumonia, though the effect on mortality is unclear. We review the association of ICS with the risk of pneumonia and the implications on clinical outcomes.

    Community-acquired pneumonia (CAP) is one of the most common reasons for physician visits and hospitalizations in North America. Rates of CAP increase with age and CAP is associated with significant morbidity and mortality, especially in the elderly. Though there is much written about the epidemiology and risk factors of incident (first episode) pneumonia, much less is known about recurrent pneumonia. Rates of recurrent pneumonia within 3-5-years of an episode of CAP are 9-12% with a median time to recurrence of 123-317 days and mortality ranging from 4 to 10%. Age ≥65-years-old and impaired functional status are the only patient characteristics that are independently associated with increased risk of recurrence. In terms of modifiable risk factors, only the use of proton-pump inhibitors and systemic and inhaled corticosteroids have consistently been associated with increased risk of recurrent pneumonia, while angiotensin-converting enzyme (ACE) inhibitors may exert a protective effect. Many chronic medical conditions typically associated with increased incident pneumonia-such as chronic obstructive pulmonary disease (COPD), neurological disease (resulting in dysphagia or silent aspiration), and heart failure-were not associated with increased risk of recurrent pneumonia. However, those who are immune-suppressed (e.g., immunoglobulin deficiencies) may be at increased risk of recurrent pneumonia. In summary, among those who survive an episode of pneumonia, recurrence is not uncommon, particularly in the elderly. Following recovery from an episode of pneumonia, patients should be evaluated for risk factors that would predispose to a second episode including seeking evidence of immunosuppression in younger patients and medication optimization, particularly in the elderly.

    Full Text Available Abstract Background Pneumococcal diseases remain a major cause of morbidity and mortality worldwide. Updated data on drug-resistance from different populations may be important to recognize changes in disease patterns. This study assessed current levels of penicilin resistance among Streptococcus Pneumoniae causing pneumonia in Spanish middle age and older adults. Methods Antimicrobial susceptibility was tested for 104 consecutive isolates of Streptococcus pneumoniae recovered from patients 50 years or older with radiographically confirmed pneumonia in the region of Tarragona (Spain between 2002 and 2007. According to the minimum inhibitory concentration of tested antimicrobials (penicillin, erythromycin, cefotaxime and levofloxacin strains were classified as susceptible or resistant. Antimicrobial resistance was determined for early cases (2002–2004 and contemporary cases (2005–2007. Results Twenty-seven (25.9% were penicillin-resistant strains (19 strains with intermediate resistance and 8 strains with high resistance. Penicillin-resistance was higher in 2002–2004 than in 2005–2007 (39.5% vs 18.2%, p = 0.017. Of 27 penicillin-resistant strains, 10 (37% were resistant to erythromycin, 8 (29.6% to cefotaxime, 2 (7.4% to levofloxacin, and 4 (14.8% were identified as multidrug resistant. Case-fatality rate was higher among those patients who had an infection caused by any penicillin susceptible strain (16.9% than in those with infections due to penicillin-resistant strains. Conclusion Resistance to penicillin among Streptococcus pneumoniae remains high, but such resistance does not result in increased mortality in patients with pneumococcal pneumonia.

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.

    Research in context: Pneumonia continues to be a high-burden illness around the globe. This paper shows that although research funding is increasing in the UK (between 1997 and 2013, it remains poorly funded compared to other important respiratory infectious diseases such as tuberculosis and influenza. Publications about pneumonia have been steadily increasing over time, indicating continuing academic and clinical interest in the topic. Though global mortality of pneumonia is declining, it should still be an area of high priority for funders, policymakers and researchers.

    Findings on electrocardiogram may hint that pulmonary embolism (PE) is present when interpreted in the proper context and lead to definitive imaging tests. However, it would be useful to know if electrocardiographic (ECG) abnormalities also occur in patients with pneumonia and whether these are similar to ECG changes with PE. The purpose of this investigation was to determine ECG findings in patients with pneumonia. We retrospectively evaluated 62 adults discharged with a diagnosis of pneumonia who had no previous cardiopulmonary disease and had electrocardiogram obtained during hospitalization. The most prevalent ECG abnormality, other than sinus tachycardia, was minor nonspecific ST-segment or T-wave changes occurring in 13 of 62 (21%). Right atrial enlargement occurred in 4 of 62 (6.5%). QRS abnormalities were observed in 24 of 62 (39%). Right-axis deviation and S(1)S(2)S(3) were the most prevalent QRS abnormalities, which occurred in 6 of 62 (9.7%). Complete right bundle branch block and S(1)Q(3)T(3) pattern occurred in 3 of 62 (4.8%). ECG abnormalities that were not present within 1 month previously or abnormalities that disappeared within 1 month included left-axis deviation, right-axis deviation, right atrial enlargement, right ventricular hypertrophy, S(1)S(2)S(3), S(1)Q(3)T(3), low-voltage QRS complexes, and nonspecific ST-segment or T-wave abnormalities. In conclusion, electrocardiogram in patients with pneumonia often shows QRS abnormalities or nonspecific ST-segment or T-wave changes. ECG findings are similar to ECG abnormalities in PE and electrocardiogram cannot assist in the differential diagnosis.

    Full Text Available In the absence of livestock contact, recurring lamb mortality in bighorn sheep (Ovis canadensis populations previously exposed to pneumonia indicates the likely presence of carriers of pneumonia-causing pathogens, and possibly inadequate maternally derived immunity. To investigate this problem we commingled naïve, pregnant ewes (n=3 with previously exposed rams (n=2. Post-commingling, all ewes and lambs born to them acquired pneumonia-causing pathogens (leukotoxin-producing Pasteurellaceae and Mycoplasma ovipneumoniae, with subsequent lamb mortality between 4-9 weeks of age. Infected ewes became carriers for two subsequent years and lambs born to them succumbed to pneumonia. In another experiment, we attempted to suppress the carriage of leukotoxin-producing Pasteurellaceae by administering an antibiotic to carrier ewes, and evaluated lamb survival. Lambs born to both treatment and control ewes (n=4 each acquired pneumonia and died. Antibody titers against leukotoxin-producing Pasteurellaceae in all eight ewes were ‘protective’ (>1:800 and no apparent respiratory disease; however their lambs were either born with comparatively low titers, or with high (but non-protective titers that declined rapidly within 2-8 weeks of age, rendering them susceptible to fatal disease. Thus, exposure to pneumonia-causing pathogens from carrier ewes, and inadequate titers of maternally derived protective antibodies, are likely to render bighorn lambs susceptible to fatal pneumonia.

    Streptococcus pneumoniae (Strep. pneumoniae) is the main cause of bacterial pneumonia in children less than 5 years of age, with high mortality rates in developing countries. In 1993, the Regional System for Vaccines Group (SIREVA) of the pan-American Health Organisation (PAHO) began a study involving six Latin American countries to identify serotypes and their representativity in the new conjugated vaccines, and to determine the degree of resistance to penicillin. Serotypes 14 (highest resistance level), 5, 1, 6A/B, 23F, 7F, 9V, 19F, 18C, 19A, 9N, were prevalent in the region, with some differences among countries. Although resistance to penicillin ranged from 2% (Brazil) to 21.1% (Mexico), studies have shown that pneumonia caused by Strep. pneumoniae with diminished sensitivity to penillin can be treated with this antibiotic. Only 58% of the serotypes isolated in the region studied were represented in the seven-valent vaccine. Continual surveillance is essential to determine which formulation of conjugated vaccine will be suitable for use in Latin America.

    Full Text Available This study examined the spatial distribution of childhood community-acquired pneumonia detected through prospective surveillance in Goiânia, Brazil. Three spatial analysis techniques were applied to detect intra-urban geographic aggregation of pneumonia cases: Kernel method, nearest neighbor hierarchical technique, and spatial scan statistic. A total of 724 pneumonia cases confirmed by chest radiography were identified from May 2000 to August 2001. All cases were geocoded on a digital map. The annual pneumonia risk rate was estimated at 566 cases/100,000 children. Analysis using traditional descriptive epidemiology showed a mosaic distribution of pneumonia rates, while GIS methodologies showed a non-random pattern with hot spots of pneumonia. Cluster analysis by spatial scan statistic identified two high-risk areas for pneumonia occurrence, including one most likely cluster (RR = 2.1; p < 0.01 and one secondary cluster (RR = 1.3; p = 0.01. The data used for the study are in line with recent WHO-led efforts to improve and standardize pediatric pneumonia surveillance in developing countries and show how GIS and spatial analysis can be applied to discriminate target areas of pneumonia for public heath intervention.

    Klebsiella pneumoniae is an important emerging pathogen in humans, particularly the invasive hypermucoviscosity (HMV) phenotype. In addition, the organism is an important public health concern because of nosocomial infections and antimicrobial resistance. Nonhuman primates in captivity are susceptible to Klebsiella, particularly when a stress factor is involved. Infections vary depending on the species but can cause significant morbidity and mortality in these animals. The objective of this study was to describe a case of bronchopneumonia and bacteremia caused by Klebsiella pneumoniae in a free-ranging golden-headed lion tamarin (Leontopithecus chrysomelas) caught and maintained in quarantine during a translocation program for conservation purposes. An adult male, that had showed emaciation and apathy, was clinically examined and, despite being provided supportive therapy, died 2 days after onset of clinical signs. At postmortem examination, generalized bilateral pneumonia and pericarditis were observed. Tissue samples were fixed in 10% formalin for histology, and pulmonary tissues and cardiac blood were collected for microbiologic diagnostic procedures. Bacteria that were shown to be HMV K. pneumoniae subsp. pneumoniae strains were isolated from the pulmonary fluids and cardiac blood in pure cultures. Severe bronchopneumonia was the main pathological finding. The consequences of the confirmed presence of the HMV phenotype of K. pneumoniae subsp. pneumoniae in this wildlife species for human, animal, and ecosystem health should be determined. These results demonstrate the importance of quarantine and potential pathogen screening during wildlife translocation procedures.

    Full Text Available Background/Aim. Pneumonia is the most frequent complication in acute psychotropic drugs poisoning, which results in substantial morbidity and mortality, but which also increases the costs of treatment. Risk factors for pneumonia are numerous: age, sex, place of the appearance of pneumonia, severity of underlying disease, airway instrumentation (intubation, reintubation, etc. The incidence of pneumonia varies in poisoning caused by the various groups of drugs. The aim of this study was to determine the incidence and risk factors for pneumonia in the patients with acute psychotropic drugs poisoning. Methods. A group of 782 patients, out of which 614 (78.5% with psychotropic and 168 (21.5% nonpsychotropic drug poisoning were analyzed prospectively during a two-year period. The diagnosis of pneumonia was made according to: clinical presentation, new and persistent pulmonary infiltrates on chest radiography, positive nonspecific parameters of inflammation, and the microbiological confirmation of causative microorganisms. To analyze predisposing risk factors for pneumonia, the following variables were recorded: sex, age, underlying diseases, endotracheal intubation, coma, severity of poisoning with different drugs, histamine H2 blockers, corticosteroids, mechanical ventilation, central venous catheter. The univariate analysis for pneumonia risk factors in all patients, and for each group separately was done. The multivariate analysis was performed using the logistic regression technique. Results. Pneumonia was found in 94 (12.02% of the patients, 86 of which (91.5% in psychotropic and 8 (8.5% in nonpsychotropic drug poisoning. In the psychotropic drug group, pneumonia was the most frequent in antidepressant (47%, and the rarest in benzodiazepine poisoning (3.8%. A statistically significant incidence of pneumonia was found in the patients with acute antidpressant poisoning (p < 0.001. Univariate analysis showed statistical significance for the

    Klebsiella pneumoniae, a chief cause of nosocomial pneumonia, is a versatile and commonly multidrug-resistant human pathogen for which further insight into pathogenesis is needed. We show that the pilus regulatory gene fimK promotes the virulence of K. pneumoniae strain TOP52 in murine pneumonia. This contrasts with the attenuating effect of fimK on urinary tract virulence, illustrating that a single factor may exert opposing effects on pathogenesis in distinct host niches. Loss of fimK in TOP52 pneumonia was associated with diminished lung bacterial burden, limited innate responses within the lung, and improved host survival. FimK expression was shown to promote serum resistance, capsule production, and protection from phagocytosis by host immune cells. Finally, while the widely used K. pneumoniae model strain 43816 produces rapid dissemination and death in mice, TOP52 caused largely localized pneumonia with limited lethality, thereby providing an alternative tool for studying K. pneumoniae pathogenesis and control within the lung.

    Klebsiella pneumoniae strains producing K. pneumoniae carbapenemase (KPC) cause serious infections in debilitated and immunocompromised patients and are associated with prolonged hospital stays and increased mortality rates. Daptomycin is a lipopeptide used against Staphylococcus aureus infection and considered inactive against Gram-negative bacteria. We investigated the effectiveness of a daptomycin-meropenem combination by synergy kill curve and a pharmacokinetic/pharmacodynamic model. The combination may represent a novel therapeutic strategy against infections caused by KPC-producing K. pneumoniae strains.

    Workers employed in 15 utilities that generate nuclear power in the United States have been followed for up to 18 years between 1979 and 1997. Their cumulative dose from whole-body ionizing radiation has been determined from the dose records maintained by the facilities themselves and the REIRS and REMS systems maintained by the Nuclear Regulatory Commission and the Department of Energy, respectively. Mortality in the cohort from a number of causes has been analyzed with respect to individual radiation doses. The cohort displays a very substantial healthy worker effect, i.e. considerably lower cancer and noncancer mortality than the general population. Based on 26 and 368 deaths, respectively, positive though statistically nonsignificant associations were seen for mortality from leukemia (excluding chronic lymphocytic leukemia) and all solid cancers combined, with excess relative risks per sievert of 5.67 (95% confidence interval (CI) -2.56, 30.4) and 0.596 (95% CI -2.01, 4.64), respectively. These estimates are very similar to those from the atomic bomb survivors study, though the wide confidence intervals are also consistent with lower or higher risk estimates. A strong positive and statistically significant association between radiation dose and deaths from arteriosclerotic heart disease including coronary heart disease was also observed in the cohort, with an ERR of 8.78 (95% CI 2.10, 20.0). Whle associations with heart disease have been reported in some other occupational studies, the magnitude of the present association is not consistent with them and therefore needs cautious interpretation and merits further attention. At present, the relatively small number of deaths and the young age of the cohort (mean age at end of follow-up is 45 years) limit the power of the study, but further follow-up is 45 years) limit the power of the study, but further follow-up and the inclusion of the present data in an ongoing IARC combined analysis of nuclear workers from 15

    Rhabdomyosarcoma is the most common soft-tissue sarcoma in children; it can appear in any part of the body. Its biological behavior varies widely, and despite the absence of specific clinical or radiological characteristics, rhabdomyosarcoma should be taken into account in the differential diagnosis of solid tumors in children. This review focuses primarily on the imaging findings and anatomical distribution of the histological subtypes of childhood rhabdomyosarcoma and secondarily on the differential findings in histological studies.

    Full Text Available OBJECTIVE : To analyze studies that evaluated the role of infections as well as indirect measures of exposure to infection in the risk of childhood leukemia, particularly acute lymphoblastic leukemia. METHODS : A search in Medline, Lilacs, and SciELO scientific publication databases initially using the descriptors “childhood leukemia” and “infection” and later searching for the words “childhood leukemia” and “maternal infection or disease” or “breastfeeding” or “daycare attendance” or “vaccination” resulted in 62 publications that met the following inclusion criteria: subject aged ≤ 15 years; specific analysis of cases diagnosed with acute lymphoblastic leukemia or total leukemia; exposure assessment of mothers’ or infants’ to infections (or proxy of infection, and risk of leukemia. RESULTS : Overall, 23 studies that assessed infections in children support the hypothesis that occurrence of infection during early childhood reduces the risk of leukemia, but there are disagreements within and between studies. The evaluation of exposure to infection by indirect measures showed evidence of reduced risk of leukemia associated mainly with daycare attendance. More than 50.0% of the 16 studies that assessed maternal exposure to infection observed increased risk of leukemia associated with episodes of influenza, pneumonia, chickenpox, herpes zoster, lower genital tract infection, skin disease, sexually transmitted diseases, Epstein-Barr virus, and Helicobacter pylori . CONCLUSIONS : Although no specific infectious agent has been identified, scientific evidence suggests that exposure to infections has some effect on childhood leukemia etiology.

    Full Text Available Imogen Johns Department of Clinical Sciences and Services, Royal Veterinary College, North Mymms, UK Abstract: Rhodococcus equi, a gram-positive facultative intracellular bacterial pathogen, is the most important cause of pneumonia in foals aged 3 weeks to 5 months. The disease occurs worldwide, resulting in significant morbidity and mortality on endemically affected farms. Foals appear to become infected early in life, but clinical signs are typically delayed until 1–3 months of age because of the insidious nature of the disease. Although pneumonia is the most common clinical manifestation, up to 74% of foals may concurrently have extrapulmonary disorders, including both extrapulmonary infections (abdominal abscessation, colitis, osteomyelitis and immune-mediated disorders (nonseptic synovitis, uveitis. Diagnosis is based on the combination of clinical signs and abnormalities on hematologic screening and thoracic imaging in an appropriately aged foal and is confirmed by bacteriologic culture of the organism. Management of R. equi infections, in particular on farms with endemic disease, combines appropriate treatment of affected foals with preventative measures targeted at preventing infection and identifying foals before the development of severe disease. The combination of rifampin and a macrolide antimicrobial is recommended for treatment, as the combination is synergistic, reaches high intracellular concentrations, and should minimize the development of antimicrobial resistance. The prognosis for survival for foals with R. equi pneumonia is good, especially in foals mildly or subclinically affected, as is the prognosis for future athletic performance. Screening for early identification before the development of clinical signs has been advocated on endemically affected farms, although the most appropriate method, the timing of screening, and the selection of foals requiring treatment have yet to be determined. Recent evidence suggests that

    Full Text Available BACKGROUND: Pneumococcal infections cause major morbidity and mortality in developing countries. We report the epidemiology of S. pneumoniae carriage in a developing region, the Gaza strip, and evaluate the theoretical coverage of carriage strains by pneumococcal conjugate vaccines (PCVs. METHODOLOGY: In 2009 we conducted a cross-sectional survey of S. pneumoniae carriage in healthy children and their parents, living throughout the Gaza strip. Data were collected and nasopharyngeal swabs were obtained. Antibiotic susceptibilities were determined by Vitek-2 and serotypes by the Quellung reaction. PRINCIPAL FINDINGS: S. pneumoniae carriage was detected in 189/379 (50% of children and 30/376 (8% of parents. Carriage prevalence was highest in children <6 months of age (63%. Significant predictors for child carriage were number of household members and DCC attendance. The proportion of pediatric and adults isolates with serotypes included in PCV7 were 32% and 20% respectively, and 46% and 33% in PCV13 respectively. The most prominent non-vaccine serotypes (NVT were 35B, 15B/C and 23B. Penicillin-nonsusceptible strains were carried by 70% of carriers, penicillin-resistant strains (PRSP by 13% and Multi-drug-resistant (MDR by 30%. Of all PRSP isolates 54% belonged to serotypes included in PCV7 and 71% in the PCV13. Similarly, 59% and 73% of MDR-SP isolates, would theoretically be covered by PCV7 and PCV13, respectively. CONCLUSIONS: This study demonstrates that, PCV13-included strains were carried by 46% and 33% of pediatric and adult subjects respectively. In the absence of definitive data regarding the virulence of the NVT strains, it is difficult to predict the effect of PCVs on IPD in this region.

    China, as a whole, is about to meet the Millennium Development Goals for reducing the maternal mortality ratio (MMR) and infant mortality rate (IMR), but the disparities between rural area and urban area still exists. This study estimated the potential effectiveness of expanding coverage with high impact interventions using the Lives Saved Tool (LiST). It was found that gestational hypertension, antepartum and postpartum hemorrhage, preterm birth, neonatal asphyxia, and neonatal childhood pneumonia and diarrhea are still the major killers of mothers and children in rural area in China. It was estimated that 30% of deaths among 0-59 month old children and 25% of maternal deaths in 2008 could be prevented in 2015 if primary health care intervention coverage expanded to a feasible level. The LiST death cause framework, compared to data from the Maternal and Child Mortality Surveillance System, represents 60%-80% of neonatal deaths, 40%-50% of deaths in 1-59 month old children and 40%-60% of maternal deaths in rural areas of western China.

    Kuate-Defo, Barthélémy; Diallo, Khassoum

    2002-06-01

    After decades of sustained child mortality reductions, infant and early childhood mortality levels in Africa remain high. This can partly be ascribed to the concentration of child mortality within particular families, communities or geographic localities. Strong mortality clustering is indicative of marked social inequality and of an unequal distribution of health and health-related resources and infrastructures. It also signifies a concentration of nutritional and sanitary behaviors harmful to the good health and longevity of children. Finally, it likely points to the existence of particular genetic problems in certain families, or environmental problems within specific communities. Using nationally representative family level data from all sub-regions of Africa, two important findings emerge from this study. First, levels of mortality have generally declined in all countries over time, and as mortality decreases, mortality clustering tends to follow the same trend. Second, bio-demographic covariates have a more important effect on familial mortality clustering risks than socio-economic ones.

    Streptococcus pneumoniae is the most common causative pathogen in community-acquired pneumonia (CAP). Granzyme A (GzmA) is a serine protease produced by a variety of cell types involved in the immune response. We sought to determine the role of GzmA on the host response during pneumococcal pneumonia. GzmA was measured in bronchoalveolar lavage fluid (BALF) harvested from CAP patients from the infected and contralateral uninfected side and in lung tissue slides from CAP patients and controls. In CAP patients, GzmA levels were increased in BALF obtained from the infected lung. Human lungs showed constitutive GzmA expression by both parenchymal and nonparenchymal cells. In an experimental setting, pneumonia was induced in wild-type (WT) and GzmA-deficient (GzmA(-/-)) mice by intranasal inoculation of S. pneumoniae In separate experiments, WT and GzmA(-/-) mice were treated with natural killer (NK) cell depleting antibodies. Upon infection with S. pneumoniae, GzmA(-/-) mice showed a better survival and lower bacterial counts in BALF and distant body sites compared with WT mice. Although NK cells showed strong GzmA expression, NK cell depletion did not influence bacterial loads in either WT or GzmA(-/-) mice. These results implicate that GzmA plays an unfavorable role in host defense during pneumococcal pneumonia by a mechanism that does not depend on NK cells.

The aim of our study was to analyse the risk of suicide among childhood cancer survivors compared with that ofthe general population of Slovenia. Patients and methods. This retrospective study included patients with childhood cancer registeredat the Cancer Registry of Slovenia between 1978-2008, with an observation period of 1978-2010. Childhood cancer patients and controlsubjects from the general population of Slovenia were matched by sex,year and age at the beginning of follow-up and time of follow-up inyears. Data on the general population of Slovenia were obtained fromthe Statistical Office of the Republic of Slovenia. Results. A total of 1647 patients were recorded in the Cancer Registry as having cancerduring childhood, with 3 patients committing suicide. All three weremale. Their age at diagnosis of cancer was 12, 13 and 2 years old; their age at suicide was 19, 32 and 28 years old. The mechanism of death was asphyxiation in all three deaths. The calculation of the expected number of suicides in the group of individuals with childhood cancer from the general Slovene population revealed the number of 3.16persons. Conclusion. The comparison of the observed and expectedprobability showed that there was no statistically significant difference in the suicide rate between childhood cancer survivors and the general population of Slovenia.

    after vaccination, 133 were secondary to influenza. 9. The death rate for 155 cases of pneumonia (all types) that developed among vaccinated men 1 week or more after vaccination was only 12.2 per cent, whereas the death rate for 327 cases of all types that occurred among unvaccinated troops was 22.3 per cent. The death rate for primary pneumonia among vaccinated troops was 11.9 per cent. Among unvaccinated, it was 31.8 per cent, almost three times as great. On the other hand, the mortality rate in pneumonia secondary to influenza is about the same for the vaccinated and unvaccinated groups. 10. In conclusion, it must be admitted that the results of pneurnococcus vaccination at Camp Wheeler have not been so striking as those obtained at Camp Upton in 1918, largely on account of the influenza epidemic; but, although influenza obscured to some extent the effect of pneumococcus vaccination at Camp Wheeler, the results are sufficiently encouraging to justify its further application in civil as well as in military life.

    Pneumonia, the inflammatory state of lung tissue primarily due to microbial infection, claimed 52,306 lives in the United States in 2007 (1) and resulted in the hospitalization of 1.1 million patients (2). With an average length of in-patient hospital stay of five days (2), pneumonia and influenza comprise significant financial burden costing the United States $40.2 billion in 2005 (3). Under the current Infectious Disease Society of America/American Thoracic Society guidelines, standard-of-care recommendations include the rapid administration of an appropriate antibiotic regiment, fluid replacement, and ventilation (if necessary). Non-standard therapies include the use of corticosteroids and statins; however, these therapies lack conclusive supporting evidence (4). (Figure 1) Osteopathic Manipulative Treatment (OMT) is a cost-effective adjunctive treatment of pneumonia that has been shown to reduce patients' length of hospital stay, duration of intravenous antibiotics, and incidence of respiratory failure or death when compared to subjects who received conventional care alone (5). The use of manual manipulation techniques for pneumonia was first recorded as early as the Spanish influenza pandemic of 1918, when patients treated with standard medical care had an estimated mortality rate of 33%, compared to a 10% mortality rate in patients treated by osteopathic physicians (6). When applied to the management of pneumonia, manual manipulation techniques bolster lymphatic flow, respiratory function, and immunological defense by targeting anatomical structures involved in the these systems(7,8, 9, 10). The objective of this review video-article is three-fold: a) summarize the findings of randomized controlled studies on the efficacy of OMT in adult patients with diagnosed pneumonia, b) demonstrate established protocols utilized by osteopathic physicians treating pneumonia, c) elucidate the physiological mechanisms behind manual manipulation of the respiratory and

    Objective To describe the clinical features of reported cases of community-acquired pneumonia (CAP) due to methicillin-resistant Staphylococcus aureus (MRSA), and to evaluate the risk factors related to outcome. Methods A systematic search of databases from January 1995 to December 2009 was performed. Baseline characteristics of survivors and non-survivors in the hospital were compared with the χ2 test for categorical variables. Variables with P<0.2 were entered in Logistic regression. Survival analysis was estimated by the Kaplan-Meier method according to use of antimicrobials inhibiting toxin production. Results Fifty-two articles were identified reporting data on 74 patients, with 41.1% of total mortality, short duration of symptom onset to death [(6.1±11.0) days], and prolonged hospital admissions [(28.6±29.1) days]. Logistic regression analysis showed that influenza like symptoms (P=0.04), hemoptysis (P<0.01), leucopenia (P<0.01) were the risk factors associated with death, and using clindamycin or linezolid which could inhibit the Panton-Valentine leukocidin (PLV, P<0.01) was the factor associated with survival. Kaplan-Meier analysis indicated that the antibiotic therapies inhibiting toxin production were associated with improved outcome in these cases (χ2=21.59, P<0.01). Conclusion CAP due to MRSA is a severe disease with significant lethality. Empiric therapy of severe CAP with flu-like symptoms, hemoptysis and leucopenia should include coverage for MRSA. Targeted treatment with antimicrobials inhibiting toxin production appear to be more appropriate selection.%目的 揭示社区获得性耐甲氧西林金黄色葡萄球菌(CA-MRSA)肺炎临床特征及死亡相关危险因素.方法 系统检索1995年1月至2009年12月发表的中英文文献,对比分析CA-MRSA肺炎生存和死亡者的临床特征,对相关参数进行Logistic回归分析以探讨与死亡的关系.按照是否应用抑制杀白细胞素(PVL)治疗措施分层,对患

    This document updates and replaces CDC's previously published "Guideline for Prevention of Nosocomial Pneumonia" (Infect Control 1982;3:327-33, Respir Care 1983;28:221-32, and Am J Infect Control 1983;11:230-44). This revised guideline is designed to reduce the incidence of nosocomial pneumonia and is intended for use by personnel who are responsible for surveillance and control of infections in acute-care hospitals; the information may not be applicable in long-term-care facilities because of the unique characteristics of such settings. This revised guideline addresses common problems encountered by infection-control practitioners regarding the prevention and control of nosocomial pneumonia in U.S. hospitals. Sections on the prevention of bacterial pneumonia in mechanically ventilated and/or critically ill patients, care of respiratory-therapy devices, prevention of cross-contamination, and prevention of viral lower respiratory tract infections (e.g., respiratory syncytial virus [RSV] and influenza infections) have been expanded and updated. New sections on Legionnaires disease and pneumonia caused by Aspergillus sp. have been included. Lower respiratory tract infection caused by Mycobacterium tuberculosis is not addressed in this document. Part I, "An Overview of the Prevention of Nosocomial Pneumonia, 1994, provides the background information for the consensus recommendations of the Hospital Infection Control Practices Advisory Committee (HICPAC) in Part II, Recommendations for Prevention of Nosocomial Pneumonia." Pneumonia is the second most common nosocomial infection in the United States and is associated with substantial morbidity and mortality. Most patients who have nosocomial pneumonia are infants, young children, and persons > 65 years of age; persons who have severe underlying disease, immunosuppression, depressed sensorium, and/or cardiopulmonary disease and persons who have had thoracoabdominal surgery.

    Community-acquired pneumonia remains a most widespread acute infectious disease of socio-economic significance all over the world. Up to 30% of the patients present with anemia responsible for the unfavourable prognosis and elevated mortality. Not infrequently, anemia is not diagnosed during the hospital stay und therefore remains uncorrected. Severe anemia results in enhanced hypercapnia and slowed maturation of red blood cells in the bone marrow which facilitates the development of ischemic syndrome. Hepcidin, a mediator of inflammation and iron-regulatory hormone, plays an important role in the clinical course of community-acquired pneumonia. Hepsidin production increases during inflammation; it suppresses erythtropoiesis and depletes the iron depot leading to so-called anemia of inflammation. Hypoxia and anemia activate erythtropoiesis, and the released erythropoietin inhibits hepsidin production. During pneumonia resolution, hepsidin promotes recovery from anemia by activating iron absorption. The curreni literature contains few data on the use of hepcidin as a diagnostic marker of anemia. The necessity oftreating anemia in patients with pneumonia under hospital conditions is a matter of discussion. Direct involvement of hepcidin in iron metabolism creates a prerequisite for the treatment of anemia. Medicamental suppression of its activity by stimulating erythtropoiesis can facilitate normalization of iron metabolism and restoration of hemoglobin level.

    Postinfluenza pneumococcal pneumonia is an important cause of global morbidity and mortality. What causes this increased susceptibility is not well elucidated. IL-35 is a newly described cytokine in infectious tolerance. A murine model was established to study postinfluenza pneumococcal pneumonia and evaluate the role of IL-35 in host defense against postinfluenza pneumococcal pneumonia. Pulmonary IL-35 was rapidly up-regulated during murine influenza infection, which was partially mediated by type I IFN-α/β receptor signaling pathway. Secondary pneumococcal infection led to a synergistic IL-35 response in influenza-infected mice. Clinical analysis showed that IL-35 levels were significantly elevated in the patients with influenza infection compared with healthy individuals and influenza infection could induce IL-35 production from human peripheral blood mononuclear cells. These data suggest that IL-35 contributes to the increased susceptibility to secondary pneumococcal pneumonia at least in part by inhibiting the early immune response.

    Pneumonia is the second most common nosocomial infection in the United States and is associated with substantial morbidity and mortality. Most patients with nosocomial pneumonia are those with extremes of age, severe underlying disease, immunosuppression, depressed sensorium, and cardiopulmonary disease, and those who have had thoracoabdominal surgery. Although patients with mechanically assisted ventilation do not comprise a major proportion of patients with nosocomial pneumonia, they have the highest risk of developing the infection. Most bacterial nosocomial pneumonias occur by aspiration of bacteria colonizing the oropharynx or upper gastrointestinal tract of the patient. Intubation and mechanical ventilation greatly increase the risk of nosocomial bacterial pneumonia because they alter first-line patient defenses. Pneumonias due to Legionella spp., Aspergillus spp., and influenza virus are often caused by inhalation of contaminated aerosols. Respiratory syncytial virus (RSV) infection usually follows viral inoculation of the conjunctivae or nasal mucosa by contaminated hands. Traditional preventive measures for nosocomial pneumonia include decreasing aspiration by the patient, preventing cross-contamination or colonization via hands of personnel, appropriate disinfection or sterilization or respiratory therapy devices, use of available vaccines to protect against particular infections, and education of hospital staff and patients. New measures under investigation involve reducing oropharyngeal and gastric colonization by pathogenic microorganisms.

    Pneumonia in the elderly often occurs repeatedly, and the mortality rate from pneumonia continues to remain high today despite the usual use of antibacterial chemotherapy. Therefore, we conducted immunotherapy using a polyvalent bacterial vaccine (broncasma Berna). We treated 54 elderly patients with Broncasma Berna, containing chief bacterial pathogens responsible for pneumonia in the elderly. Clinical results obtained during 2 years were compared with those of 18 subjects not treated with Broncasma Berna. The survival rate was 64.8% for the group treated with Broncasma Berna and 50% for the group not treated. The frequency of contraction of pneumonia decreased significantly in the group treated. Clinical efficacy was obtained in 63% of the group treated to prevent pneumonia. The death rate from pneumonia was 17.6% for the group treated and 44.4% for the group not treated. Immunologically, reinforcement in humoral and cellular immunities was indicated by immunoglobulin values, positive tuberculin skin tests, and an increase in lymphocyte stimulation index values for Broncasma Berna. Significant pathogens in sputum disappeared or decreased in 6 (54.6%) out of 11 patients. Side effects such as pain or redness at the site of injection were observed in 6 patients. From the above results, it may be concluded that Broncasma Berna can be considered to be effective as a long-term immunoprophylactic agent in the prevention of pneumonia in the elderly.

    Bacterial dermatosepticemia, a systemic infectious bacterial disease of frogs, can be caused by several opportunistic gram-negative bacterial species including Aeromonas hydrophila, Chryseobacterium indologenes, Chryseobacterium meningosepticum, Citrobacter freundii, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, and Serratia liquifaciens. Here we determined the pathogenicity of 3 bacterial species (Aeromonas hydrophila, Klebsiella pneumoniae, and Proteus mirabilis) associated with an outbreak of fatal dermatosepticemia in New Zealand Litoria ewingii frogs. A bath challenge method was used to expose test frogs to individual bacterial species (2 x 10(7) cfu/mL in pond water); control frogs were exposed to uninfected pond water. None of the control frogs or those exposed to A. hydrophila or P. mirabilis showed any morbidity or mortality. Morbidity and mortality was 40% among frogs exposed to K. pneumonia, and the organism was reisolated from the hearts, spleens, and livers of affected animals.

    Infections caused by Streptococcus pneumoniae are a major cause of mortality throughout the world. Protein-based pneumococcal vaccines are envisaged to replace or complement the current polysaccharide-based vaccines. In this context, detoxified pneumolysin (dPly) and pneumococcal histidine triad protein D (PhtD) are two potential candidates for incorporation into pneumococcal vaccines. In this study, the protective efficacy of a PhtD-dPly vaccine was evaluated in a rhesus macaque (Macaca mulatta) model of pneumonia. The animals were immunized twice with 10 μg of PhtD and 10 μg of dPly formulated in the Adjuvant System AS02 or with AS02 alone, before they were challenged with a 19F pneumococcal strain. The survival was significantly higher in the protein-vaccinated group and seemed to be linked to the capacity to greatly reduce bacterial load within the first week post-challenge. Vaccination elicited high concentrations of anti-PhtD and anti-Ply antibodies and a link was found between survival and antibody levels. In conclusion, AS02-adjuvanted PhtD-dPly vaccine protects against S. pneumoniae-induced pneumonia. It is probable that the protection is at least partially mediated by PhtD- and Ply-specific antibodies.

    Idiopathic interstitial pneumonias comprise 8 clinicopathological entities, most of them with a chronic course and various prognosis. Idiopathic pulmonary fibrosis is the most frequent and most severe of these. Computed tomography has an important role for its diagnosis. It can identify the corresponding pathological pattern of usual interstitial pneumonia in about 50 percent of cases. It can suggest differential diagnosis in other cases, most frequently fibrosing nonspecific interstitial pneumonia and chronic hypersensitivity pneumonitis. Imaging features should be integrated to clinical and available pathologic data during multidisciplinary team meetings involving physicians with a good knowledge of interstitial diseases. Some cases may be unclassifiable, but these could later be reclassified as new data may occur or imaging features may change. Surgical lung biopsy is being less frequently performed and an emerging less invasive technique, lung cryobiopsy, is under evaluation. Pleuroparenchymal fibroelastosis is a distinct entity only recently described, with uncertain prevalence and prognosis that seems being quite often associated to another pattern of interstitial pneumonia.

    Mycoplasma pneumoniae is a leading cause of respiratory disease. In the Intensive Care Unit (ICU) setting M. pneumoniae is not considered a common pathogen. In 2010-13 an epidemic of M. pneumoniae-associated infections was reported and we observed an increase of M. pneumoniae patients admitted to ICU. We analysed the cohort of all M. pneumoniae-positive patients' admissions during 2007 to 2012 at the Hadassah-Hebrew University Medical Centre (a 1100-bed tertiary medical centre). Mycoplasma pneumoniae diagnosis was made routinely using PCR on throat swabs and other respiratory samples. Clinical parameters were retrospectively extracted. We identified 416 M. pneumoniae-infected patients; of which 68 (16.3%) were admitted to ICU. Of these, 48% (173/416) were paediatric patients with ICU admission rate of 4.6% (8/173). In the 19- to 65-year age group ICU admission rate rose to 18% (32/171), and to 38.8% (28/72) for patients older than 65 years. The mean APACHE II score on ICU admission was 20, with a median ICU stay of 7 days, and median hospital stay of 11.5 days. Of the ICU-admitted patients, 54.4% (37/68) were mechanically ventilated upon ICU admission. In 38.2% (26/68), additional pathogens were identified mostly later as secondary pathogens. A concomitant cardiac manifestation occurred in up to 36.8% (25/68) of patients. The in-hospital mortality was 29.4% (20/68) and correlated with APACHE II score. Contrary to previous reports, a substantial proportion (16.3%) of our M. pneumoniae-infected patients required ICU admission, especially in the adult population, with significant morbidity and mortality.

    Pneumonia is a major cause of morbidity and mortality worldwide. Early diagnosis of the etiologic agent is important in order to choose the correct antibiotic treatment. In this study we evaluated the first commercial combined test for the agents of pneumococcal pneumonia and Legionnaires' disease based on urinary antigen detection, the ImmuView® Streptococcus pneumoniae and Legionella pneumophila Urinary Antigen Test. In this evaluation, the new test had a significantly higher sensitivity than the BinaxNOW® lateral flow tests and the Binax® EIA test. This identifies the ImmuView® S. pneumoniae and L. pneumophila Urinary Antigen Test as a fast and sensitive point of care test for identification of the infectious agent in a major group of patients with pneumonia.

    Coinfection with bacteria is a major cause of mortality during influenza epidemics. Recently, Toll-like receptor (TLR) agonists were shown to have immunomodulatory functions. In the present study, we investigated the effectiveness and mechanisms of the new TLR4 agonistic monoclonal antibody UT12 against secondary pneumococcal pneumonia induced by coinfection with influenza virus in a mouse model. Mice were intranasally inoculated with Streptococcus pneumoniae 2 days after influenza virus inoculation. UT12 was intraperitoneally administered 2 h before each inoculation. Survival rates were significantly increased and body weight loss was significantly decreased by UT12 administration. Additionally, the production of inflammatory mediators was significantly suppressed by the administration of UT12. In a histopathological study, pneumonia in UT12-treated mice was very mild compared to that in control mice. UT12 increased antimicrobial defense through the acceleration of macrophage recruitment into the lower respiratory tract induced by c-Jun N-terminal kinase (JNK) and nuclear factor kappaB (NF-κB) pathway-dependent monocyte chemoattractant protein 1 (MCP-1) production. Collectively, these findings indicate that UT12 promoted pulmonary innate immunity and may reduce the severity of severe pneumonia induced by coinfection with influenza virus and S. pneumoniae. This immunomodulatory effect of UT12 improves the prognosis of secondary pneumococcal pneumonia and makes UT12 an attractive candidate for treating severe infectious diseases.

    Community-acquired pneumonia remains a major cause of mortality in developed countries. There is much discrepancy in the literature regarding factors influencing the outcome in the elderly population. Data were derived from a multicentre prospective study initiated by the German Competence Network for Community-Acquired Pneumonia. Patients with community-acquired pneumonia (n = 2,647; 1,298 aged or = 65 yrs) were evaluated, of whom 72.3% were hospitalised and 27.7% treated in the community. Clinical history, residence status, course of disease and antimicrobial treatment were prospectively documented. Microbiological investigations included cultures and PCR of respiratory samples and blood cultures. Factors related to mortality were included in multivariate analyses. The overall 30-day mortality was 6.3%. Elderly patients exhibited a significantly higher mortality rate that was independently associated with the following: age; residence status; confusion, urea, respiratory frequency and blood pressure (CURB) score; comorbid conditions; and failure of initial therapy. Increasing age remained predictive of death in the elderly. Nursing home residents showed a four-fold increased mortality rate and an increased rate of gram-negative bacillary infections compared with patients dwelling in the community. The CURB score and cerebrovascular disease were confirmed as independent predictors of death in this subgroup. Age and residence status are independent risk factors for mortality after controlling for comorbid conditions and disease severity. Failure of initial therapy was the only modifiable prognostic factor.

This paper aims at describing the clinical characteristics, the laboratory findings, the complications, and the therapeutic management of these patients, who have been suffering from this disease since 1993 to 2006. METHOD: Twelve children with Streptococcus pneumoniae meningoencephalitis admitted to the pediatric hospital of San Miguel del Padron, City of Havana in this period were assessed. RESULTS: Children under one year are the most frequently affected. Septic shock and brain edema were the most severe complications. Three patients died, implying that this disease has a serious course. Early treatment of brain edema is very important to reduce mortality. The elective drugs for treatment of these cases of Streptococcus pneumoniae meningoencephalitis were vancomycin combined with cephalosporin, cefotaxime or ceftriaxone type. CONCLUSION: Patients with Streptococcus pneumoniae meningoencephalitis show clinical characteristics, complications, and sequels that are different to other bacterial meningoencephalitis, meaning that they could be helpful for physicians considering the differential diagnosis of meningoencephalitis.OBJETIVO: Existe un incremento de la meningoencefalitis producida por Streptococcus pneumoniae, después de las campañas exitosas de vacunación contra Neisseria meningitidis y Haemophilus influenzae.

    ABSTRACT Epidemiological studies on Streptococcus pneumoniae show that rates of carriage are highest in early childhood and that the major benefit of the pneumococcal conjugate vaccine (PCV) is a reduction in the incidence of nasopharyngeal colonization through decreased transmission within a population. In this study, we sought to understand how anti-S. pneumoniae immunity affects nasal shedding of bacteria, the limiting step in experimental pneumococcal transmission. Using an infant mouse model, we examined the role of immunity (passed from mother to pup) on shedding and within-litter transmission of S. pneumoniae by pups infected at 4 days of life. Pups from both previously colonized immune and PCV-vaccinated mothers had higher levels of anti-S. pneumoniae IgG than pups from non-immune or non-vaccinated mothers and shed significantly fewer S. pneumoniae over the first 5 days of infection. By setting up cross-foster experiments, we demonstrated that maternal passage of antibody to pups either in utero or post-natally decreases S. pneumoniae shedding. Passive immunization experiments showed that type-specific antibody to capsular polysaccharide is sufficient to decrease shedding and that the agglutinating function of immunoglobulin is required for this effect. Finally, we established that anti-pneumococcal immunity and anti-PCV vaccination block host-to-host transmission of S. pneumoniae. Moreover, immunity in either the donor or recipient pups alone was sufficient to reduce rates of transmission, indicating that decreased shedding and protection from acquisition of colonization are both contributing factors. Our findings provide a mechanistic explanation for the reduced levels of S. pneumoniae transmission between hosts immune from prior exposure and among vaccinated children. PMID:28292980

    highest immune response was obtained 14 days post 1st dose of immunization with extracted CPSs of the three Klebsiella pneumoniae subspecies. When mice were immunized with CPSs of Klebsiella pneumoniae subspecies, they were protected against virulent challenge with homologous or heterologous strains, as a result the mortality rates were reduced from 80, 75 and 65 to 5 to 15% of Klebsiella pneumoniae subsp. pneumoniae, Klebsiella pneumoniae subsp. ozaenae and Klebsiella pneumoniae subsp. rhinoscleromatis, respectively. Determination of the reisolation rates of Klebsiella pneumoniae subspecies from lung, liver and spleen were done on both immunized mice and challenged and on control mice. Histopathological studies have been done on both dead infected non-immunized and immunized mice. Lungs were the main organs that showed macroscopic and microscopic pathological changes. Finally, ELISA has been used for detection of CPSs of Klebsiella pneumoniae subspecies antibodies in sera of examined animals. The sensitivity of ELISA using CPSs extracted from Klebsiella pneumoniae subsp. pneumoniae, Klebsiella pneumoniae subsp. ozaenae and Klebsiella pneumoniae subsp. rhinoscleromatis was 87.7, 89.0 and 83.6%, respectively. The specificity of this ELISA was 93.4, 92.9 and 93.1%, respectively. ELISA using CPSs antigens could therefore serve as a valuable aid in serodiagnosis of Klebsiella pneumonia.

    Although Haemophilus influenzae is a common etiologic agent of pneumonia in patients infected with human immunodeficiency virus (HIV), the characteristics of this pneumonia have not been adequately assessed. We have prospectively studied features of H. influenzae pneumonia in 26 consecutive HIV-infected inpatients. Most of these patients were severely immunosuppressed; 73.1% had a CD4+ cell count <100/microL. A subacute clinical presentation was observed in 27% of the patients and was associated with a higher degree of immunosuppression (P=.04). Bilateral lung infiltrates were noted radiographically in 57.7% of the cases. The mortality attributable to H. influenzae pneumonia was 11.5%. Thus, pneumonia caused by H. influenzae affects mainly patients with advanced HIV disease, and since its clinical and radiological features may be diverse, this etiology should be considered when pneumonia occurs in patients with advanced HIV infection. The mortality rate associated with H. influenzae pneumonia is not higher than that occurring in the general population.

    Pneumonia is a frequent complication in dementia patients and is associated with high mortality rates. The aim of this retrospective cohort study was to determine whether traditional Chinese medicine (TCM) therapy can decrease pneumonia risk in dementia patients. The cohort dataset was obtained from the Longitudinal Health Insurance Database 2005, a sublibrary of the National Health Insurance Research Database, containing all medical data of 1 million beneficiaries, randomly selected from the all Insurers in year 2005.Newly diagnosed dementia patients (n = 9712) without pneumonia were analyzed from January 1997 to December 2003. After matching by sex, age, urban level, Charlson comorbidity index, insured amount, and comorbidities, 1376 pairs (1:1) of TCM and non-TCM users were acquired. Every dementia patient was individually recorded from 1997 to 2012 to identify pneumonia incidence (onset after 3 months of dementia diagnosis).Demographic characteristics, Charlson comorbidity index, comorbidities, behavioral and psychological symptoms of dementia, and psychotropic drugs were also investigated. Cox proportional regression was used to compute hazard ratios and 95% confidence intervals (CIs) after adjustment for the above-mentioned variables.There were 419 (30.5%) and 762 (55.4%) pneumonia cases in the TCM and non-TCM cohorts during a mean follow-up period of 7.6 years. The adjusted hazard ratios (95% CI) for pneumonia admission was 0.62 (0.55-0.70) for the TCM group.Patients who received TCM therapy at higher cumulative doses or for longer periods experienced increased protection from pneumonia admission. Ma-Xing-Gan-Shi-Tang, Yin-Qiao-San, and Xiao-Qing-Long-Tang might represent possible formulae reducing the incidence of pneumonia. TCM might be associated with a lower risk of pneumonia in dementia patients.

    2016-10-01

    Background: Nursing home-acquired pneumonia (NHAP) has been identified as one of the leading causes of mortality and hospitalization for long-term care residents. However, current and previous pneumonia guidelines differ on the appropriate management of NHAP in hospitalized patients, specifically in regard to the role of atypical bacteria such as Chlamydiae pneumonia, Mycoplasma pneumoniae, and Legionella. Objectives: The purpose of this review is to evaluate clinical trials conducted in hospitalized patients with NHAP to determine the prevalence of atypical bacteria and thus the role for empiric antibiotic coverage of these pathogens in NHAP. Methods: Comprehensive MEDLINE (1966-April 2016) and Embase (1980-April 2016) searches were performed using the terms "atypical bacteria", "atypical pneumonia", "nursing-home acquired pneumonia", "pneumonia", "elderly", "nursing homes", and "long term care". Additional articles were retrieved from the review of references cited in the collected studies. Thirteen published clinical trials were identified. Results: In the majority of studies, atypical bacteria were infrequently identified in patients hospitalized with NHAP. However, when an active community-acquired pneumonia (CAP) cohort was available, the rate of atypical bacteria between NHAP and CAP study arms was similar. Only 3 studies in this review adhered to recommended strategies for investigating atypical bacteria; in 2 of these studies, C. pneumoniae was the most common pathogen identified in NHAP cohorts. Conclusion: Although atypical bacteria were uncommon in most NHAP studies in this review, suboptimal microbial investigations were commonly performed. To accurately describe the role of atypical bacteria in NHAP, more studies using validated diagnostic tests are needed.

    Full Text Available Abstract Background Most guidelines have been proposing, for more than 15 years, a β-lactam combined with either a quinolone or a macrolide as empirical, first-line therapy of severe community acquired pneumonia (CAP requiring ICU admission. Our goal was to evaluate the outcome of patients with severe CAP, focusing on the impact of new rather than old fluoroquinolones combined with β-lactam in the empirical antimicrobial treatments. Methods Retrospective study of consecutive patients admitted in a 16-bed general intensive care unit (ICU, between January 1996 and January 2009, for severe (Pneumonia Severity Index > or = 4 community-acquired pneumonia due to non penicillin-resistant Streptococcus pneumoniae and treated with a β-lactam combined with a fluoroquinolone. Results We included 70 patients of whom 38 received a β-lactam combined with ofloxacin or ciprofloxacin and 32 combined with levofloxacin. Twenty six patients (37.1% died in the ICU. Three independent factors associated with decreased survival in ICU were identified: septic shock on ICU admission (AOR = 10.6; 95% CI 2.87-39.3; p = 0.0004, age > 70 yrs. (AOR = 4.88; 95% CI 1.41-16.9; p = 0.01 and initial treatment with a β-lactam combined with ofloxacin or ciprofloxacin (AOR = 4.1; 95% CI 1.13-15.13; p = 0.03. Conclusion Our results suggest that, when combined to a β-lactam, levofloxacin is associated with lower mortality than ofloxacin or ciprofloxacin in severe pneumococcal community-acquired pneumonia.

    Abstract Background: Pneumonia is a common and serious infectious disease that can cause high mortality. The role of lung ultrasound (LUS) in the diagnosis of pneumonia is becoming more and more important. Methods: In the present study, we collected existing evidence regarding the use of LUS to diagnose pneumonia in adults and conducted a systematic review to summarize the technique's diagnostic accuracy. We specifically searched the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Embase databases and retrieved outcome data to evaluate the efficacy of LUS for the diagnosis of pneumonia compared with chest radiography or chest computed tomography. The pooled sensitivity (SEN) and specificity (SPE) were determined using the Mantel–Haenszel method, and the pooled diagnostic odds ratio (DOR) was determined using the DerSimonian–Laird method. We also assessed heterogeneity of sensitivity, specificity, and diagnostic odds ratio using the Q and I2 statistics. Results: Twelve studies containing 1515 subjects were included in our meta-analysis. The SEN and SPE were 0.88 (95% CI: 0.86–0.90) and 0.86 (95% CI: 0.83–0.88), respectively. The pooled negative likelihood ratio (LR) was 0.13 (95% CI: 0.08–0.23), the positive LR was 5.37 (95% CI: 2.76–10.43), and the DOR was 65.46 (95% CI: 29.24–146.56). The summary receiver operating characteristic curve indicated a relationship between sensitivity and specificity. The area under the curve for LUS was 0.95. Conclusion: LUS can help to diagnose adult pneumonia with high accuracy. PMID:28099332

    Interstitial pneumonia (IP) and chronic obstructive pulmonary disease (COPD) are representative diseases of restrictive pulmonary dysfunction and obstructive pulmonary dysfunction, respectively. In the preoperative anesthesia clinic, anesthesiologists are frequently asked to assess the anesthesia management of patients with these diseases. In respiratory function tests, IP is detected as a decrease in % vital capacity (< 80%), and COPD as a decrease in % FEV1.0 (< 70%). Other key factors which affect the assessment are; 1) severity assessment that affects the safety of anesthesia management, 2) prognostic evaluation including the acute exacerbation in the postoperative period, and 3) patient-related factors (age, life degree of autonomy, other comorbidities, surgery-related factors, and anesthesia method). In the patients in the disease stage I or II, anesthesia management is relatively safe. On the other hand, the patients in the disease stage IV have no surgical indication except life-saving emergent situation. In another words, anesthesiologists are required to make the judgment for the anesthesia management of the patient in the disease stage III, based on the assessment of patient-related factors, surgery-related factors, and prognosis.

    The prevalence of childhood obesity is rising rapidly, as are the associated medical complications, including type 2 diabetes, hypertension, and coronary heart disease. This has significant medical and socioeconomic implications. The definition of obesity in adults is based on body mass index (BMI), which has been correlated with morbidity and mortality. Similarly, the definition of childhood obesity is currently based on BMI; however, there are currently no data to relate morbidity and mortality to BMI values in children. The known and potential causes of childhood obesity are many, but they can be categorized as genetic, endocrine, prenatal/early life, physical activity, diet, and socioeconomic. These factors influence the basic equation: energy input = energy output. Imbalances in this equation can result in obesity. Here we present a review of recent literature and highlight the etiologies, certain complications, and potential prevention and treatment strategies of childhood obesity.

  3. Influenza excess mortality from 1950-2000 in tropical Singapore.

    Vernon J Lee

    Full Text Available INTRODUCTION: Tropical regions have been shown to exhibit different influenza seasonal patterns compared to their temperate counterparts. However, there is little information about the burden of annual tropical influenza epidemics across time, and the relationship between tropical influenza epidemics compared with other regions. METHODS: Data on monthly national mortality and population was obtained from 1947 to 2003 in Singapore. To determine excess mortality for each month, we used a moving average analysis for each month from 1950 to 2000. From 1972, influenza viral surveillance data was available. Before 1972, information was obtained from serial annual government reports, peer-reviewed journal articles and press articles. RESULTS: The influenza pandemics of 1957 and 1968 resulted in substantial mortality. In addition, there were 20 other time points with significant excess mortality. Of the 12 periods with significant excess mortality post-1972, only one point (1988 did not correspond to a recorded influenza activity. For the 8 periods with significant excess mortality periods before 1972 excluding the pandemic years, 2 years (1951 and 1953 had newspaper reports of increased pneumonia deaths. Excess mortality could be observed in almost all periods with recorded influenza outbreaks but did not always exceed the 95% confidence limits of the baseline mortality rate. CONCLUSION: Influenza epidemics were the likely cause of most excess mortality periods in post-war tropical Singapore, although not every epidemic resulted in high mortality. It is therefore important to have good influenza surveillance systems in place to detect influenza activity.

    Objective A high genomic load of Pneumococcus from blood or cerebrospinal fluid has been associated with increased mortality. We aimed to analyse whether nasopharyngeal colonisation density in HIV-infected patients with community-acquired pneumonia (CAP) is associated with markers of disease severity or poor outcome. Methods Quantitative lytA real-time PCR was performed on nasopharyngeal swabs in HIV-infected South African adults hospitalised for acute CAP at Chris Hani Baragwanath Hospital, Soweto, South Africa. Pneumonia aetiology was considered pneumococcal if any sputum culture or Gram stain, urinary pneumococcal C-polysaccharide-based antigen, blood culture or whole blood lytA real-time PCR revealed pneumococci. Results There was a moderate correlation between the mean nasopharyngeal colonisation densities and increasing CURB65 scores among all-cause patients with pneumonia (Spearman correlation coefficient r=0.15, p=0.06) or with the Pitt bacteraemia score among patients with pneumococcal bacteraemia (p=0.63). In patients with pneumococcal pneumonia, nasopharyngeal pneumococcal colonisation density was higher among non-survivors than survivors (7.7 vs 6.1 log10 copies/mL, respectively, p=0.02) and among those who had pneumococci identified from blood cultures and/or by whole blood lytA real-time PCR than those with non-bacteraemic pneumococcal pneumonia (6.6 vs 5.6 log10 copies/mL, p=0.03). Nasopharyngeal colonisation density correlated positively with the biomarkers procalcitonin (Spearman correlation coefficient r=0.37, p<0.0001), proadrenomedullin (r=0.39, p=0.008) and copeptin (r=0.30, p=0.01). Conclusions In addition to its previously reported role as a diagnostic tool for pneumococcal pneumonia, quantitative nasopharyngeal colonisation density also correlates with mortality and prognostic biomarkers. It may also be useful as a severity marker for pneumococcal pneumonia in HIV-infected adults. PMID:25113557

  10. PEGylated liposomal vancomycin: a glimmer of hope for improving treatment outcomes in MRSA pneumonia.

    Science.gov (United States)

    Pumerantz, Andrew S

    2012-12-01

    Methicillin-resistant Staphylococcus aureus (MRSA) plays a significant role in the pandemic of multidrug resistant bacterial infections and is a major cause of hospital-acquired pneumonia. MRSA pneumonia carries a high morbidity and mortality rate especially in elderly diabetics with chronic kidney disease. S. aureus is highly virulent and successful respiratory pathogen. Vancomycin and linezolid are the only two antimicrobial agents FDA-approved to treat MRSA pneumonia. Standard vancomycin dosing is associated with high clinical failure rates and higher dosages are associated with increased nephrotoxicity. Pharmacokinetic and pharmacodynamic limitations are major contributors to poor outcomes with vancomycin. New agents are needed to improve treatment outcomes with MRSA pneumonia. Recently released antimicrobials with in vitro activity are not FDA-approved for treating MRSA pneumonia. Other novel agents are being investigated though none are in late-stage development. Pharmaceutical industry perception of low returns on investment, a Sisyphean regulatory environment, and obstacles to patentability have contributed to declining interest in both the development of novel antibiotics and the improvement of existing generic formulations. Despite decades of investigation into liposomal encapsulation as a drug delivery system that would increase efficacy and decrease toxicity, only liposomal amphotericin B and doxorubicin are commercially available. In this article, the pharmacokinetics and biodistribution of a novel PEGylated liposomal vancomycin formulation along with passive targeting and the enhanced permeability and retention effect of liposomal drug delivery; the pathogenesis of MRSA pneumonia; and recent patents of novel anti-MRSA agents, including inhalational liposomal vancomycin, are reviewed.

  11. Fluoroquinolones in community-acquired pneumonia: guide to selection and appropriate use.

    2011-04-16

    Fluoroquinolone use has dramatically increased since the introduction of the first respiratory fluoroquinolone in the late 1990s. Over a relatively brief period of time, the respiratory fluoroquinolones have supplanted other first-line options as the predominant community-acquired pneumonia (CAP) therapy in hospitals. This article discusses the rise of the fluoroquinolone era, debates the comparative effectiveness of fluoroquinolones for CAP therapy, examines fluoroquinolone resistance and adverse drug reactions, and discusses new trends in pneumonia epidemiology and outcomes assessment. Overall, published data suggest that fluoroquinolone monotherapy is associated with improved patient survival compared with β-lactam monotherapy and similar survival to β-lactam plus macrolide combination therapy. Fluoroquinolone monotherapy may be associated with shorter hospital length of stay compared with β-lactam plus macrolide combination therapy, particularly in severe pneumonia or with high-dose therapy. There is insufficient evidence to conclude that any individual fluoroquinolone therapy is better than another with regards to patient mortality. Fluoroquinolones are generally well tolerated and Streptococcus pneumoniae resistance remains low; however, rare but serious adverse effects have been reported. Some members of the fluoroquinolone class have been removed from the market amidst safety concerns. Pneumonia classifications have changed and antipseudomonal fluoroquinolones may have a role in healthcare-associated pneumonia when administered in combination with other antipseudomonal and anti-methicillin-resistant Staphylococcus aureus therapies.

    Pneumococcal pneumonia is a leading cause of mortality worldwide. The inflammatory response to bacteria is necessary to control infection, but it may also contribute to tissue damage. Phosphodiesterase-4 inhibitors, such as rolipram (ROL), effectively reduce inflammation. Here, we examined the impact of ROL in a pneumococcal pneumonia murine model. Mice were infected intranasally with 10(5)-10(6) CFU of Streptococcus pneumoniae, treated with ROL in a prophylactic or therapeutic schedule in combination, or not, with the antibiotic ceftriaxone. Inflammation and bacteria counts were assessed, and ex vivo phagocytosis assays were performed. ROL treatment during S. pneumoniae infection decreased neutrophil recruitment into lungs and airways and reduced lung injury. Prophylactic ROL treatment also decreased cytokine levels in the airways. Although modulation of inflammation by ROL ameliorated pneumonia, bacteria burden was not reduced. On the other hand, antibiotic therapy reduced bacteria without reducing neutrophil infiltration, cytokine level, or lung injury. Combined ROL and ceftriaxone treatment decreased lethality rates and was more efficient in reducing inflammation, by increasing proresolving protein annexin A1 (AnxA1) expression, and bacterial burden by enhancing phagocytosis. Lack of AnxA1 increased inflammation and lethality induced by pneumococcal infection. These data show that immunomodulatory effects of phosphodiesterase-4 inhibitors are useful during severe pneumococcal pneumonia and suggest their potential benefit as adjunctive therapy during infectious diseases.

    Background Pneumonia and urinary tract infections (UTIs) increase morbidity and mortality. There is little epidemiological evidence from large population-based studies on risk factors for these infections and subsequent mortality in total hip arthroplasty (THA) patients. Aim To examine the risk factors of postoperative pneumonia and UTI after THA and their impact on survival. Patients and methods We used the Danish Hip Arthroplasty Register to identify THAs due to osteoarthritis registered from 2000 to 2013. We collected data about comorbidities, mortality and infections in relation to primary hospitalization and potential predictive variables from administrative databases. Regression models were used to estimate associations between potential risk factors and infection, and subsequently, between infection and mortality. Results In total 84,812 THAs were included. The cumulative incidence of pneumonia and UTI within 7 days of the primary procedure were 0.21 (95% confidence interval [CI]: 0.18–0.25) and 0.29 (95% CI: 0.26–0.33), respectively. Patient-related risk factors for infection were being 80 years or older, gender and a comorbidity burden at time of surgery. The hazard ratio (HR) of dying within 90 days of the primary THA was 10.67 (95% CI: 5.79–19.57) compared to patients without pneumonia. For patients with UTIs, the HR was 1.64 (95% CI: 0.41–6.59) compared to those without a UTI. Conclusion Pneumonia was associated with an increased short-term risk of dying, despite adjustment for coexisting comorbidity and other potential confounders. Age, gender and comorbidity were the most important risk factors for pneumonia and UTIs. Individual initiatives to reduce the risk of pneumonia in select patient groups may be essential to the effort to optimize outcomes after a THA. PMID:28176979

    Exploiting pre-intervention variation in flu/pneumonia, tuberculosis and maternal mortality, together with time variation arising from medical breakthroughs starting in the late 1930s, this paper studies the aggregate impact of large health shocks across US states. The analysis demonstrates...... that the shocks influenced income per capita in different ways. While the shock to flu/pneumonia mortality has been conductive for development, the large reduction in the incidence of tuberculosis deaths has been a negative force in the development of US states over the second-half of 20th century.

    Full Text Available A 67-year-old man suffering from esophageal cancer was admitted to our hospital complaining of dyspnea and hypoxemia. He had been treated with cisplatin, docetaxel, and fluorouracil combined with radiotherapy. Chest computed tomography revealed bilateral ground-glass opacity, and bronchoalveolar lavage fluid showed increased eosinophils. Two episodes of transient eosinophilia in peripheral blood were observed after serial administration of anticancer drugs before the admission, and drug-induced lymphocyte stimulation test to cisplatin was positive. Thus cisplatin-induced eosinophilic pneumonia was suspected, and corticosteroid was effectively administered. To our knowledge, this is the first reported case of cisplatin-induced eosinophilic pneumonia.

    Enterobacter species have increasingly been identified as pathogens over the past several decades. These bacterial species have become more important because most are resistant to cephalothin and cefoxitin, and can produce extended-spectrum {beta}-lactamase. Enterobacter asburiae (E. asburiae) is a gram-negative rod of the family Enterobacteriaceae, named in 1986. Since then, there has been only one clinical report of E. asburiae pneumonia. We report a case of E. asburiae pneumonia with cavitation and compare it with the previous case.

    Mortality tables play important role in actuarial studies such as life annuities, premium determination, premium reserve, valuation pension plan, pension funding. Some known mortality tables are CSO mortality table, Indonesian Mortality Table, Bowers mortality table, Japan Mortality table. For actuary applications some tables are constructed with different environment such as single decrement, double decrement, and multiple decrement. There exist two approaches in mortality table construction : mathematics approach and statistical approach. Distribution model and estimation theory are the statistical concepts that are used in mortality table construction. This article aims to discuss the statistical approach in mortality table construction. The distributional assumptions are uniform death distribution (UDD) and constant force (exponential). Moment estimation and maximum likelihood are used to estimate the mortality parameter. Moment estimation methods are easier to manipulate compared to maximum likelihood estimation (mle). However, the complete mortality data are not used in moment estimation method. Maximum likelihood exploited all available information in mortality estimation. Some mle equations are complicated and solved using numerical methods. The article focus on single decrement estimation using moment and maximum likelihood estimation. Some extension to double decrement will introduced. Simple dataset will be used to illustrated the mortality estimation, and mortality table.

    Full Text Available Acute respiratory tract infections may trigger acute asthma attacks and may be held responsible for etiopathogenesis in children with asthma. Although bacterial infections attract a limited amount of attention, recently Chlamydia pneumoniae (CP and Mycoplasma pneumoniae (MP, in particular, are reported to be the possible factors. IgM and IgG seroprevalence was investigated in 66 children patients with bronchial asthma (between the ages of 3 and 14 for CP and Mycoplasma pneumoniae. In a total of 66 cases, 18 (27.2% patients were detected with IgG positivity for CP whereas 27 of them (40.9% were detected with IgG positivity for MP. IgG positivity was determined in 6 patients (13.0% in the control group for CP, and in 6 patients (10.8% in the control group for MP. The rate of the asthma patients with IgG seropositivity for MP was 4 times higher than that of the control group. It was seen that IgG antibody seropositivity for CP was higher in those with more frequent attacks. No such difference was observed in terms of IgG antibody seropositivity for M. pneumoniae. There are many studies indicating that CP and MP infections take an importance place in the etiology of bronchial asthma and asthma attacks in children. The results obtained reveal the effect of both microorganisms on the etiopathogenesis of the bronchial asthma and the increased number of asthma attacks.

    This study describes the molecular characteristics and risk factors associated with carbapenem-resistant Klebsiella pneumoniae strains. Risk factors associated with KPC-producing K. pneumoniae strains were investigated in this case-control study from May 2011 to May 2013. Bacterial identification was performed by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS). Antimicrobial susceptibility was determined by broth microdilution. Carbapenemase production was assessed by both modified Hodge test (MHT) and ertapenem hydrolysis using MALDI-TOF MS. The presence of β-lactamase-encoding genes was evaluated by PCR and DNA sequencing. Alterations in genes encoding K. pneumoniae outer membrane proteins were analysed by PCR and DNA sequencing as well as SDS-PAGE. Genetic relatedness among strains was determined by pulsed-field gel electrophoresis. This study included 94 patients. Longer hospitalisation, mechanical ventilation, catheters, and previous surgery were associated with KPC-producing K. pneumoniae. Sixty-eight strains showed resistance to carbapenems. Carbapenemase production was detected by MHT in 67 K. pneumoniae strains and by MALDI-TOF MS in 57. The presence of the blaKPC-2 gene was identified in 57 strains. The blaKPC-2 gene was not found in 11 carbapenem-resistant K. pneumoniae; instead, the blaCTX-M-1-like, blaCTX-M-2-like, blaCTX-M-8 like, blaCTX-M-14-like and blaSHV- like genes associated with OmpK35 and OmpK36 alterations were observed. Thirty-three KPC-producing K. pneumoniae strains were clonally related, and patients infected with these strains had a higher mortality rate (78.78 %). Our results show that KPC-producing K. pneumoniae was associated with several healthcare-related risk factors, including recent surgery.

    Full Text Available Abstract Background Anemic syndrome is a frequent problem in intensive care units. The most probable etiology is the suppression of the erythropoietin response due to the direct effects of cytokines, as well as frequent blood sampling. Transfusions are not free of complications, therefore transfusion reactions are estimated to occur in 2% of the total packed red blood cells (pRBCs transfused. In the past several years, several trials had tried to compare the restrictive with the more liberal use of transfusions, and they were found to be equally effective. Nosocomial pneumonia is the most common nosocomial infection in intensive care units; the prevalence is 47% with an attributive mortality of 33%. There are multiple risk factors for the development of nosocomial pneumonia. Colonization of the upper airways is the most important pathophysiological factor but there are other factors implicated like, sedation techniques, inappropriate use of antibiotics and recumbent positioning. A secondary analysis of the CRIT study describes transfusion therapy and its practices in the United States. They found that transfusion practice is an independent risk factor for the development of nosocomial pneumonia. Methods This is a multicenter, prospective cohort study in different intensive care units in Colombia. A total of 474 patients were selected who had more than 48 hours of mechanical ventilation. The primary objective is to try to demonstrate the hypothetical relationship between the use of transfusions and nosocomial pneumonia. Secondly, we will try to determine which other factors are implicated in the development of pneumonia in intensive care units and describe the incidence of pneumonia and transfusion practices. Discussion Ventilator associated pneumonia is a primary problem in the intensive care unit, multiple factors have been associated with its presence in this study we try to explore the possible association between pneumonia and transfusion

    Bacterial pneumonia remains associated with high morbidity and mortality. The gram-positive pathogen Streptococcus pneumoniae is the most common cause of community-acquired pneumonia. Lipoteichoic acid (LTA) is an important proinflammatory component of the gram-positive bacterial cell wall. R-roscovitine, a purine analog, is a potent cyclin-dependent kinase (CDK)-1, -2, -5 and -7 inhibitor that has the ability to inhibit the cell cycle and to induce polymorphonuclear cell (PMN) apoptosis. We sought to investigate the effect of R-roscovitine on LTA-induced activation of cell lines with relevance for lung inflammation in vitro and on lung inflammation elicited by either LTA or viable S. pneumoniae in vivo. In vitro R-roscovitine enhanced apoptosis in PMNs and reduced tumor necrosis factor (TNF)-α and keratinocyte chemoattractant (KC) production in MH-S (alveolar macrophage) and MLE-12/MLE-15 (respiratory epithelial) cell lines. In vivo R-roscovitine treatment reduced PMN numbers in bronchoalveolar lavage fluid during LTA-induced lung inflammation; this effect was reversed by inhibiting apoptosis. Postponed treatment with R-roscovitine (24 and 72 h) diminished PMN numbers in lung tissue during gram-positive pneumonia; this step was associated with a transient increase in pulmonary bacterial loads. R-roscovitine inhibits proinflammatory responses induced by the gram-positive stimuli LTA and S. pneumoniae. R-roscovitine reduces PMN numbers in lungs upon LTA administration by enhancing apoptosis. The reduction in PMN numbers caused by R-roscovitine during S. pneumoniae pneumonia may hamper antibacterial defense.

    Full Text Available Background: Diarrhea still continues to be a leading cause of childhood morbidity and mortality and holds the second rank (after pneumonia for mortality in children < 5 years of age. The majority of these deaths can be avoided by timely intervention. The knowledge of caretakers about the severity of diarrheal illness ultimately affects the choice for childcare practices and influences the type of therapies received.  Objectives: To assess the various aspect of maternal knowledge about diarrhea in under-five age children. To determine the child care practices of mothers during diarrheal episodes.Materials and methods: A cross-sectional survey was carried out from February to May 2014. 5 villages were selected by systematic random sampling method in rural field training area of medical college. A self-designed and pre-tested structured questionnaire was used as study tool which covers different aspect of knowledge and childcare practices by mothers/caretakers regarding diarrhea. Overall responses of participants were scored as good, average and poor for assessment of knowledge and practice.  Results: Total 972 mother/caretakers were interviewed. Most of the mothers/caretakers (62.1% were in favor of giving of breast milk as preferred oral fluid during diarrheal episode. Nearly one fourth of mothers/caretakers (26.1% identify symptoms and signs of "dehydration" and the need for consultation. During diarrheal episodes less amount of food and fluid was given by 49.9% and 20.4% mothers/caretaker respectively. The higher level educated and employed mothers had better practices (P < 0.001 Conclusion: The study showed that knowledge and childcare practices for diarrhea still remains a great challenge among the rural population. This could be only deals with improvement in female literacy and to develop and implement diarrhea related educational interventions for mothers/caretakers.

    2016-08-01

    Respiratory syncytial virus (RSV) is the most important viral cause of pneumonia in early childhood (ie, younger than 2 years), responsible for high infant morbidity and mortality worldwide. It is widely accepted that an effective vaccine against RSV would have a major impact on child health globally. Despite the setbacks of the clinical trials in the 1960s, there has been a recent and significant revival of interest in vaccines against RSV, with several promising candidates undergoing evaluation. In this Review, we describe the epidemiological and immunological background to RSV infection and subsequently focus on the promising pipeline of RSV vaccine development. We discuss the potential for implementation of a safe and immunogenic RSV vaccine within the context of global health and with regards to a range of strategies, including vaccination of women during pregnancy, which is likely to emerge as a beneficial and feasible public health tool. This approach would provide interim protection to vulnerable, RSV-naive infants and other high risk groups, in which the burden of admission to hospital and death is greatest. Extending research and implementation from resource-rich to resource-poor settings is required to enhance our understanding of RSV immunity and inform vaccine development and delivery strategies for all settings. We summarise key outstanding issues for researchers and policy makers to understand the interplay of biological and non-biological factors affecting design and distribution of a successful RSV vaccine globally.

    Community-acquired pneumonia is common in the elderly person; its presentation in this population is often confounded by multiple comorbid illnesses, including those that result in confusion. Although severity-of-illness scoring systems might aid decision-making, clinical judgment following a careful assessment is key in deciding on the site of care and appropriate therapy.

    Directory of Open Access Journals (Sweden)

    Ann M Nguyen

    Full Text Available BACKGROUND: In April 2009, the most recent pandemic of influenza A began. We present the first estimates of pandemic mortality based on the newly-released final data on deaths in 2009 and 2010 in the United States. METHODS: We obtained data on influenza and pneumonia deaths from the National Center for Health Statistics (NCHS. Age- and sex-specific death rates, and age-standardized death rates, were calculated. Using negative binomial Serfling-type methods, excess mortality was calculated separately by sex and age groups. RESULTS: In many age groups, observed pneumonia and influenza cause-specific mortality rates in October and November 2009 broke month-specific records since 1959 when the current series of detailed US mortality data began. Compared to the typical pattern of seasonal flu deaths, the 2009 pandemic age-specific mortality, as well as influenza-attributable (excess mortality, skewed much younger. We estimate 2,634 excess pneumonia and influenza deaths in 2009-10; the excess death rate in 2009 was 0.79 per 100,000. CONCLUSIONS: Pandemic influenza mortality skews younger than seasonal influenza. This can be explained by a protective effect due to antigenic cycling. When older cohorts have been previously exposed to a similar antigen, immune memory results in lower death rates at older ages. Age-targeted vaccination of younger people should be considered in future pandemics.

    The efficacies of tigecycline and ceftazidime against fatal pneumonia in rats caused by an extended-spectrum β-lactamase (ESBL)-positive Klebsiella pneumoniae strain or its wild-type (WT) progenitor were compared. Ceftazidime at 12.5 or 50 mg/kg of body weight twice daily (b.i.d.) was effective (50% or 100% rat survival) in pneumonia caused by the WT isolate but unsuccessful (100% rat mortality) in pneumonia caused by the ESBL-positive variant. In contrast, tigecycline at 6.25, 12.5, or 25 mg/kg b.i.d. showed dosage-dependent efficacy up to 100% rat survival irrespective of the ESBL character of the infecting organism.

    Full Text Available Abstract Background Pneumonia is one of the leading causes of morbidity and mortality in under fives. We carried out a comprehensive study to identify factors influencing both mortality and morbidity for children less than 5 years of age hospitalized with severe pneumonia. Methods 200 hospitalized children aged 2–60 months with World Health Organization (WHO defined severe pneumonia were enrolled in the study. The children were managed using a standard protocol. They were closely followed up for need for change in antibiotics, prolonged hospital stay, need for mechanical ventilation and mortality. Data on the factors influencing the outcome were collected. Results Of 200 children enrolled in the study, 113 (56.5% needed a change in antibiotics, 102 (51% stayed for more than 5 days in the hospital, 41 (20.5% needed mechanical ventilation and 21 (10.5% died. On multivariate analysis, lack of exclusive breastfeeding [RR (95%CI 2.63 (2.16–2.86], overcrowding [RR (95%CI 1.94 (1.35–2.38] and an abnormal chest x-ray [RR (95%CI 2.29 (1.22–3.44] were associated with the need for change of antibiotics. Lack of exclusive breastfeeding [RR (95%CI 2.56 (2.0–2.93], overcrowding [RR (95%CI 2.59 (1.78–3.23] and an abnormal chest x-ray [RR (95%CI 2.99 (1.65–4.38] were identified as determinants for prolonged hospital stay. Head nodding [RR (95%CI 8.34 (2.71–12.77], altered sensorium [RR (95%CI 5.44 (1.34–17.56], abnormal leukocyte counts [RR (95%CI 5.85(1.36–17.14] and pallor [RR (95%C 10.88 (2.95–20.40] were associated with mortality. Head nodding (RR (95% CI 4.73 (1.50–6.36] and cyanosis (RR (95%CI 5.06 (1.80–11.34] were the determining factors for mechanical ventilation.

    2014-01-01

    The continuous expansion of nosocomial infections around the globe has become a precarious situation. Key challenges include mounting dissemination of multiple resistances to antibiotics, the easy transmission and the growing mortality rates of hospital-acquired bacterial diseases. Thus, new ways to rapidly detect these infections are vital. Consequently, researchers around the globe pursue innovative approaches for point-of-care devices. In many cases the specific interaction of an antigen and a corresponding antibody is pivotal. However, the knowledge about suitable antigens is lacking. The aim of this study was to identify novel antigens as specific diagnostic markers. Additionally, these proteins might be aptly used for the generation of vaccines to improve current treatment options. Hence, a cDNA-based expression library was constructed and screened via microarrays to detect novel antigens of Klebsiella pneumoniae, a prominent agent of nosocomial infections well-known for its extensive antibiotics resistance, especially by extended-spectrum beta-lactamases (ESBL). After screening 1536 clones, 14 previously unknown immunogenic proteins were identified. Subsequently, each protein was expressed in full-length and its immunodominant character examined by ELISA and microarray analyses. Consequently, six proteins were selected for epitope mapping and three thereof possessed linear epitopes. After specificity analysis, homology survey and 3d structural modelling, one epitope sequence GAVVALSTTFA of KPN_00363, an ion channel protein, was identified harboring specificity for K. pneumoniae. The remaining epitopes showed ambiguous results regarding the specificity for K. pneumoniae. The approach adopted herein has been successfully utilized to discover novel antigens of Campylobacter jejuni and Salmonella enterica antigens before. Now, we have transferred this knowledge to the key nosocomial agent, K. pneumoniae. By identifying several novel antigens and their linear

    2013-01-01

    Male labor migration is widespread in many parts of the world, yet its consequences for child outcomes and especially childhood mortality remain unclear. Male labor migration could bring benefits, in the form of remittances, to the families that remain behind and thus help child survival. Alternatively, the absence of a male adult could imperil the household's well-being and its ability to care for its members, increasing child mortality risks. In this analysis, we use longitudinal survey data from Mozambique collected in 2006 and 2009 to examine the association between male labor migration and under-five mortality in families that remain behind. Using a simple migrant/non-migrant dichotomy, we find no difference in mortality rates across migrant and non-migrant men's children. When we separated successful from unsuccessful migration based on the wife's perception, however, stark contrasts emerge: children of successful migrants have the lowest mortality, followed by children of non-migrant men, followed by the children of unsuccessful migrants. Our results illustrate the need to account for the diversity of men's labor migration experience in examining the effects of migration on left-behind households. PMID:23121856

    We describe a 10 year old boy with organising pneumonia associated with acute Mycoplasma pneumoniae infection. The diagnosis of organising pneumonia was made by open lung biopsy and the M pneumoniae infection was proven serologically. Antibiotic and long term corticosteroid treatment resulted in steadily improving pulmonary function monitored by spirometry. The introduction of anti-inflammatory treatment with NSAIDs/immunosuppressive agents in order to spare steroids was well tolerated and resulted in further improvement of the pulmonary function. To our knowledge this is the first documented case of Mycoplasma pneumoniae associated organising pneumonia to be reported in a child.

    Full Text Available Although Streptococcus pneumoniae is a leading cause of childhood disease in South East Asia, little has previously been reported regarding the epidemiology of invasive pneumococcal disease in Malaysia and very few studies have explored pneumococcal epidemiology using multilocus sequence typing (MLST. Here we describe serotype, multilocus sequence type (ST, and penicillin susceptibility of thirty pneumococcal invasive disease isolates received by the University of Malaya Medical Centre between February 2000 and January 2007 and relate this to the serotypes included in current pneumococcal conjugate vaccines. A high level of diversity was observed; fourteen serotypes and 26 sequence types (ST, (11 of which were not previously described were detected from 30 isolates. Penicillin non-susceptible pneumococci accounted for 33% of isolates. The extent of molecular heterogeneity within carried and disease-causing Malaysian pneumococci remains unknown. Larger surveillance and epidemiological studies are now required in this region to provide robust evidence on which to base future vaccine policy.

MATERIALS & METHODS: All patients with endotracheal (ET tube with or without mechanical ventilation (MV in a PICU of a tertiary care teaching hospital were included in this prospective study. Clinical parameters and investigations were evaluated in patients who developed nosocomial pneumonia (NP. Colonisation of the ET tube tip was studied by culture and the antibiotic susceptibility pattern of the isolates was determined. RESULTS: Sixty-nine patients had an ET tube inserted and fifty-nine of these underwent MV. ET tube tip colonisation was seen in 70 out of 88 ET tubes inserted. The incidence of NP in patients with ET tube was 27.54% (7.96/100 days of ET intubation. NP developed only in patients undergoing MV. The main risk factors for developing NP were - duration of MV and duration of stay in the PICU. Age, sex, immunocompromised status and altered sensorium did not increase the risk of NP. The mortality in cases with NP was 47. 37%. E. coli and Klebsiella were the commonest organisms isolated from the ET tube tip cultures with maximum susceptibility to amikacin and cefotaxime. CONCLUSIONS: NP developed only in patients undergoing MV. Duration of MV and duration of stay in the PICU increased the risk of developing NP.

    Wispelwey, Brian; Schafer, Katherine R

    2010-11-01

    A literature search was conducted to evaluate the pharmacokinetic and pharmacodynamic profile of the respiratory fluoroquinolones (gemifloxacin, levofloxacin and moxifloxacin) and their efficacy and safety in the management of community-acquired pneumonia (CAP). Data show that CAP is a common presentation in primary care practice, and is associated with high rates of morbidity and mortality, particularly in the elderly. Although the causative pathogens differ depending on treatment setting and patient factors, Streptococcus pneumoniae is the primary pathogen in all treatment settings. As a class, the respiratory fluoroquinolones have a very favorable pharmacokinetic and pharmacodynamic profile. Pharmacodynamic criteria suggest that moxifloxacin and gemifloxacin are more potent against S. pneumoniae, which may have the added benefit of reducing resistance selection and enhancing bacterial eradication. The respiratory fluoroquinolones are also generally well tolerated, and are first-line options for outpatient treatment of CAP in patients with comorbidities or previous antibiotic use.

    Carbapenem-resistant Klebsiella pneumoniae strains classified as multilocus sequence type 258 (ST258) are among the most widespread multidrug-resistant hospital-acquired pathogens. Treatment of infections caused by these organisms is difficult, and mortality is high. The basis for the success of ST258, outside of antibiotic resistance, remains incompletely determined. Here we tested the hypothesis that ST258K. pneumoniae has enhanced capacity to circumvent killing by human neutrophils, the primary cellular defense against bacterial infections. There was limited binding and uptake of ST258 by human neutrophils, and correspondingly, there was limited killing of bacteria. On the other hand, transmission electron microscopy revealed that any ingested organisms were degraded readily within neutrophil phagosomes, thus indicating that survival in the neutrophil assays is due to limited phagocytosis, rather than to microbicide resistance after uptake. Our findings suggest that enhancing neutrophil phagocytosis is a potential therapeutic approach for treatment of infection caused by carbapenem-resistant ST258K. pneumoniae.

    Full Text Available Listeria Monositogenes is a facultative anaerob gram(+ agents that presents in soil, water, plants and in many mammals intestinal system.  Listeria Monositogenes is one of the most common factors of early neonatal sepsis and neonatal pneumonia during the perinatal period. Maternal obstetric complications are frequently seen in patients. Patients are often premature and have low birth weight. Responsible microorganisms frequently originate from maternal. The disease involes multisystems and the prognosis is usually fulminant.  In the congenital pneumonia, respiratory distress syndrome is prominent. Symptomatic spontaneous pneumothorax  brings about serious morbidity and mortality in newborns. The cause and risk factors of symptomatic pneumothorax in term newborns are not completely understood. The risk factors were reported as prematurity, male sex, high birth weight and birth the use of vacuum. We aimed to present a case with neonatal pneumonia associated with symptomatic spontaneous pneumothorax due to Listeria Monositogenes.

    Streptococcus pneumoniae is the leading bacterial cause of community-acquired respiratory tract infections. Prior to the 1970s this pathogen was uniformly susceptible to penicillin and most other antimicrobials. However, since the 1990s there has been a significant increase in drug-resistant Streptococcus pneumoniae (DRSP) due, in large part, to increased use of antimicrobials. The clinical significance of this resistance is not definitely established, but appears to be most relevant to specific MICs for specific antimicrobials. Certain beta-lactams (amoxicillin, cefotaxime, ceftriaxone), the respiratory fluoroquinolones, and telithromycin are among several agents that remain effective against DRSP. Continued surveillance studies, appropriate antimicrobial usage campaigns, stratification of patients based on known risk factors for resistance, and vaccination programmes are needed to appropriately manage DRSP and limit its spread.

    Full Text Available Abstract Background United Nations High Commissioner for Refugees (UNHCR refugee camps are located predominantly in rural areas of Africa and Asia in protracted or post-emergency contexts. Recognizing the importance of malaria, pneumonia and diarrheal diseases as major causes of child morbidity and mortality in refugee camps, we analyzed data from the UNHCR Health Information System (HIS to estimate incidence and risk factors for these diseases in refugee children younger than five years of age. Methods Data from 90 UNHCR camps in 16 countries, including morbidity, mortality, health services and refugee health status, were obtained from the UNHCR HIS for the period January 2006 to February 2010. Monthly camp-level data were aggregated to yearly estimates for analysis and stratified by location in Africa (including Yemen or Asia. Poisson regression models with random effects were constructed to identify factors associated with malaria, pneumonia and diarrheal diseases. Spatial patterns in the incidence of malaria, pneumonia and diarrheal diseases were mapped to identify regional heterogeneities. Results Malaria and pneumonia were the two most common causes of mortality, with confirmed malaria and pneumonia each accounting for 20% of child deaths. Suspected and confirmed malaria accounted for 23% of child morbidity and pneumonia accounted for 17% of child morbidity. Diarrheal diseases were the cause of 7% of deaths and 10% of morbidity in children under five. Mean under-five incidence rates across all refugee camps by region were: malaria [Africa 84.7 cases/1000 U5 population/month (95% CI 67.5-102.0, Asia 2.2/1000/month (95% CI 1.4-3.0]; pneumonia [Africa 59.2/1000/month (95% CI 49.8-68.7, Asia 254.5/1000/month (95% CI 207.1-301.8]; and diarrheal disease [Africa 35.5/1000/month (95% CI 28.7-42.4, Asia 69.2/1000/month (95% CI 61.0-77.5].

  9. Phenomenological theory of mortality

    Azbel, Mark Ya.

    1997-09-01

    Extensive demographic studies relate aging to the increase in mortality, terminated by the species-specific lifespan limit. Meanwhile, recent experiments demonstrate that medfly mortality decreases at older ages, and challenge a limited lifespan paradigm. This paper proves that there exists a genetically programmed probability to die at any given age, and presents its phenomenological theory. The implications of the universal mortality law crucially depend on the cohort heterogeneity. For relatively high heterogeneity the law predicts unitarily vanishing old age mortality; this is verified with medfly data. For relatively low heterogeneity it predicts a precipitous drop in mortality fluctuations in old age. This is verified with demographic data. If comprehensive studies verify a species-specific characteristic age, then that age may be genetically manipulated. If the studies verify a unitary law of mortality, the results may be generalized to all species. A phenomenological model of mortality is presented.

    The phenotypically indistinguishable Acinetobacter baumannii and Acinetobacter nosocomialis have become leading pathogens causing nosocomial pneumonia in critically ill patients. A. baumannii and A. nosocomialis nosocomial pneumonias were grouped as a single clinical entity previously. This study aimed to determine whether they are the same or a different clinical entity. A total of 121 patients with A. baumannii and 131 with A. nosocomialis bacteremic nosocomial pneumonia were included during an 8-year period. Despite the similar Charlson co-morbidity scores at admission, patients with A. baumannii pneumonia were more likely to have abnormal haematological findings, lobar pneumonia, significantly higher Acute Physiology and Chronic Health Evaluation II scores and higher frequency of shock at the onset of bacteraemia than those with A. nosocomialis pneumoni. A. baumannii isolates were resistant to more classes of antimicrobials, except colistin, and therefore the patients with A. baumannii pneumonia were more likely to receive inappropriate antimicrobial therapy. The 14-day mortality was significantly higher in patients with A. baumannii pneumonia (34.7% vs. 15.3%, p 0.001). A. baumannii was an independent risk factor for mortality (OR, 2.03; 95% CI, 1.05-3.90; p 0.035) in the overall cohort after adjustment for other risk factors for death, including inappropriate antimicrobial therapy. The results demonstrated the difference in clinical presentation, microbial characteristics and outcomes between A. baumannii and A. nosocomialis nosocomial pneumonia, and supported that they are two distinct clinical entities.

    Full Text Available Background: Community-acquired pneumonia could be a life-threatening condition especially in elderly patients. The factors influencing the outcome in elderly patients are thought to be different from those in young adults. We compared the clinical and paraclinical profiles in elderly and nonelderly patients with community-acquired pneumonias. Methods: In this cross-sectional study, seventy nine patients who were hospitalized with community acquired pneumonia over a period of one year were included. Patients' medical records were reviewed; and data related to comorbid conditions, signs and symptoms, laboratory and radiographic findings were gathered using a checklist. Results: The clinical features, laboratory parameters and complications from pneumonia were almost similar in 41 elderly (group I, age ≥65years and 38 young (group II, age<65years subjects. Delirium was seen more in elderly group (p=0.05. The average body temperature and pulse rate were significantly higher in nonelderly group. Sixty one percent of elderly patients and 21% of young patients have Po2 less than 60 (p=0.02. Smoking (29.1%, neurological disturbances (19%, congestive heart failure (15.2%, chronic obstructive pulmonary disease and diabetes mellitus (13.9% were associated comorbidities in both groups. In non elderly group, immune compromise and IV drug use were more common as underlying comorbid conditions. Two of three mortalities were due to elder patients. Conclusion: Community acquired pneumonia could have more serious clinical and abnormal laboratory features in the elderly than younger patients. Mortality rate may be higher in older patients. Comorbid conditions are frequently seen in both elderly and nonelderly patients with community acquired pneumonia, but IV drug use and immune compromise are more frequent in nonelderly patients.

    The aim of this study was to identify factors associated with mortality in intensive care unit patients with Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) septic shock. A retrospective analysis of intensive care unit patients with KPC-Kp infection and septic shock observed in a large teaching hospital from November 2010 to December 2014 was performed. A total of 111 patients were included in the study. The most frequent source of infection was unknown-focus bacteraemia in 53 patients (47.7%). The rate of resistance to colistin was 51.3%; 30-day mortality was reported for 44 patients (39.6%). Surviving patients were more frequently treated with an initial therapy (within 24 hours) including two or more antibiotics displaying in vitro activity against the isolated KPC-Kp strain (41.8 vs. 18.1%, p 0.01) and were also more likely to receive a definitive therapy including two or more in vitro active antibiotics (85.1 vs. 15.9%, p isolates was the most important determinant of favourable outcome, whilst isolation of colistin-resistant strains was associated with death in septic patients with KPC-Kp infection.

    Nosocomial infections are an important cause of preventable morbidity and mortality; they also result in significant socioeconomic cost. Nosocomial pneumonia (NCP) is defined as pneumonia, which occurs 48 hours after hospitalization or after discharge from the hospital. It is the second or third most frequent infection among all hospital acquired infections, and the mortality of NCP is higher than the other hospital acquired infections. Patients, diagnosed as NCP were retrospectively analyzed in order to detect microbiological agent and prognostic factors. We evaluated 173 patients, 67.0% of them were male and 33.0% female. Comorbid diseases were present in 94.2% and a medical procedure had been applied in 75.1% of cases. A single agent was isolated in 79.2% of the cases while a mixt infection was present in 13.3%. In 7.5% of the cases, cultures were negative. Endotracheal aspirates were the most common materials (38.9%) used for detected microorganism and sputum cultures were used in 16.8% of the cases. Most commonly encountered microorganism were Pseudomonas aeruginosa, Acinetobacter spp. and Staphylococcus aureus respectively. NCP developed on approximately 18th day of hospitalization. Overall mortality rate was 45.2%. The effects of diabetes mellitus and chronic pulmonary diseases on mortality rate were analized by logistic regression analysis and it's evaluated that the mortality rates increase 3.7 times with diabetes mellitus and 2.4 times with chronic pulmonary diseases. There was no effect of mechanical ventilation history on mortality.

    Background Community-acquired pneumonia (CAP) remains one of the leading causes ot death from infectious diseases around the world.Most severe CAP patients are admitted to the intensive care unit (ICU),and receive intense treatment.The present study aimed to evaluate the role of the pneumonia severity index (PSI),CURB-65,and sepsis score in the management of hospitalized CAP patients and explore the effect of ICU treatment on prognosis of severe cases.Methods A total of 675 CAP patients hospitalized in the Second Affiliated Hospital of Zhejiang University School of Medicine were retrospectively investigated.The ability of different pneumonia severity scores to predict mortality was compared for effectiveness,while the risk factors associated with 30-day mortality rates and hospital length of stay (LOS) were evaluated.The effect of ICU treatment on the outcomes of severe CAP patients was also investigated.Results All three scoring systems revealed that the mortality associated with the low-risk or intermediate-risk group was significantly lower than with the high-risk group.As the risk level increased,the frequency of ICU admission rose in tandem and LOS in the hospital was prolonged.The areas under the receiver operating characteristic curve in the prediction of mortality were 0.94,0.91 and 0.89 for the PSI,CURB-65 and sepsis score,respectively.Compared with the corresponding control groups,the mortality was markedly increased in patients with a history of smoking,prior admission to ICU,respiratory failure,or co-morbidity of heart disease.The differences were also identified in LOS between control groups and patients with ICU treatment,heart,or cerebrovascular disease.Logistic regression analysis showed that age over 65 years,a history of smoking,and respiratory failure were closely related to mortality in the overall CAP cohort,whereas age,ICU admission,respiratory failure,and LOS at home between disease attack and hospital admission were identified as independent

    Full Text Available Pneumonia has been considered a health problem for ages. Despite being the cause of significant morbidity and mortality. Delay in ICU admission of CAP patients has been shown to be associated with increased mortality. The ‘SMART-COP’ is a simple tool that is the result of an extensive study on CAP called the Australian CAP Study (ACAPS. OBJECTIVE To assess the validity the SMART-COP severity scoring tool in patients of Community Acquired Pneumonia (CAP. MATERIALS AND METHODS Fifty patients of CAP admitted in the intensive care units of R. L. Jalappa Hospital, Kolar, above the age of 18yrs with a diagnosis of community acquired pneumonia. RESULTS We noted a progression in the need for ICU support and need for ventilatory and ionotropic support with increasing score assigned on the SMART-COP. Thirty day mortality in the patients also showed a linear pattern with increase in the score assigned to the patients. Mortality was high in the very high risk group and high risk group. CONCLUSION With 68.5% of the patients requiring invasive ventilator support and 75% of the patients requiring inotropic support in the high risk group, it can be safely concluded that SMART-COP scoring system can be used in the patients of community acquired pneumonia to predict the need for IRVS.

    C-reactive protein (CRP) is an important molecule in the defence against bacterial infections. To discover if variation in the CRP gene is associated with clinical outcome of bacteraemia, we investigated 147 microbiologically verified bacteraemia patients (mean age 59 y, range 19-93 y) and determined whether CRP -717A>G, +1059G>C or +1444C>T single nucleotide polymorphisms (SNPs) were associated with clinical outcome of bacteraemia and/or CRP concentration caused by Staphylococcus aureus, Streptococcus pneumoniae, beta-haemolytic streptococci or Escherichia coli. The patients were genotyped for CRP gene polymorphisms, CRP was measured and clinical outcomes were recorded. The CRP -717A>G, a promoter region polymorphism was strongly associated with mortality from Streptococcus pneumoniae but did not correlate with plasma CRP concentration. These results suggest that mortality from Streptococcus pneumoniae may be associated with polymorphism of the promoter region of the CRP gene.

This article reports recent mortality data (2004–2008 for Alaska Native/American Indian (AN/AI people, comparing mortality rates to US white rates and examines changes in mortality patterns since 1980. Design . We used death record data from the state of Alaska, Department of Vital Statistics and SEER*Stat software from the National Cancer Institute to calculate age-adjusted mortality rates. Results . Annual age-adjusted mortality from all-causes for AN/AI persons during the period 2004–2008 was 33% higher than the rate for US whites (RR=1.33, 95% CI 1.29–1.38. Mortality rates were higher among AN/AI males than AN/AI females (1212/100,000 vs. 886/100,000. Cancer remained the leading cause of death among AN/AI people, as it has in recent previous periods, with an age-adjusted rate of 226/100,000, yielding a rate ratio (RR of 1.24 compared to US whites (95% CI 1.14–1.33. Statistically significant higher mortality compared to US white mortality rates was observed for nine of the ten leading causes of AN/AI mortality (cancer, unintentional injury, suicide, alcohol abuse, chronic obstructive pulmonary disease [COPD], cerebrovascular disease, chronic liver disease, pneumonia/influenza, homicide. Mortality rates were significantly lower among AN/AI people compared to US whites for heart disease (RR=0.82, the second leading cause of death. Among leading causes of death for AN/AI people, the greatest disparities in mortality rates with US whites were observed in unintentional injuries (RR=2.45 and suicide (RR=3.53. All-cause AN/AI mortality has declined 16% since 1980–1983, compared to a 21% decline over a similar period among US whites. Conclusion .

    A 4-month-old boy with past medical history of eczema presented with fever and cough; a chest radiograph showed lung consolidation, and he was initially treated with amoxicillin for presumed community-acquired pneumonia. After several days, his fever persisted. He was also profoundly anemic. Antibiotic coverage was broadened because of the concern for resistant organisms; he began to improve and was discharged from the hospital. However, at 5 months of age, his fever returned, and he continued to demonstrate lung consolidation on chest radiograph. Additionally, he had lost weight and continued to be anemic. Splenic cysts were noted on abdominal ultrasound. He was diagnosed with an unusual etiology for his pneumonia and improved with the appropriate therapy. An underlying immunodeficiency was suspected, but initial testing was nondiagnostic. At 12 months of age, he presented with another infection, and the final diagnosis was made.

    2014-06-01

    Full Text Available Backgound and Objectives: Ventilator-associated pneumonia is a pulmonary infection that occurs 48 to 72 hours after endotracheal intubation and institution of mechanical ventilation, being considered one of the most feared adverse effects of intensive care therapy. Its incidence affects 10-30% of patients as an important cause of morbidity and mortality, of which mortality rate can exceed 25%. Modifiable risk factors are seen as crucial in decision-making for its treatment and prevention. Thus, the modifiable risk factors for pneumonia associated with invasive mechanical ventilation in patients admitted to the intensive care unit were described. Methods: This is a literature review carried out at Lilacs, SciELO, MEDLINE and Bdenf databases, to collect and summarize publications and subsequently, critically evaluate the risk factors for ventilator-associated pneumonia. Results: The inappropriate or indiscriminate use of antibiotics, lack of knowledge about the microbiota of the ICU and non compliance of the team regarding preventive measures predominated. Conclusion: Professionals must be made aware of the identified risk factors in order to carry out direct actions with short-term impact in the prevention and effective control of ventilator-associated pneumonia.

    The pneumocococcal urine antigen test increases specific microbiological diagnosis over conventional culture methods in pneumonia patients. Data are limited regarding its yield and effect on antibiotic prescribing among patients with community-onset pneumonia in clinical practice. We performed a secondary analysis of 2837 emergency department patients admitted to seven Utah hospitals over 2 years with international diagnostic codes version 9 codes and radiographic evidence of pneumonia. Mean age was 64.2 years, 47.2% were male and all-cause 30-day mortality was 9.6%. Urinary antigen testing was performed in 1110 (39%) patients yielding 134 (12%) positives. Intensive care unit patients were more likely to undergo testing, and have a positive result (15% versus 8.8% for ward patients; p<0.01). Patients with risk factors for healthcare-associated pneumonia had fewer urinary antigen tests performed, but 8.4% were positive. Physicians changed to targeted antibiotic therapy in 20 (15%) patients, de-escalated antibiotic therapy in 76 patients (57%). In 38 (28%) patients, antibiotics were not changed. Only one patient changed to targeted therapy suffered clinical relapse. Length of stay and mortality were lower in patients receiving targeted therapy. Pneumococcal urinary antigen testing is an inexpensive, noninvasive test that favourably influenced antibiotic prescribing in a “real world”, multi-hospital observational study. PMID:28053969

Pneumonia was frequent in first-time exacerbations (36.1%, but declined in successive exacerbations to 25.6% by the seventh or greater exacerbation. Pneumonic COPD exacerbations increased 20% from 0.92 per 1,000 population in 2006 to 1.10 per 1,000 population in 2012. Nonpneumonic exacerbations decreased by 6% from 1.74 per 1,000 population to 1.63 per 1,000 population during the same period. A number of markers of health resource utilization were more prevalent in pneumonic exacerbations than in nonpneumonic exacerbations: length of stay (median 7 vs 4 days, intensive care unit admission (7.7% vs 12.5%, and several acute procedures. Thirty-day mortality was 12.1% in first-time pneumonic COPD exacerbations versus 8.3% in first-time nonpneumonic cases (adjusted HR [aHR] 1.20, 95% confidence interval [CI] 1.17–1.24. Pneumonia also predicted increased mortality associated with a second exacerbation (aHR 1.14, 95% CI 1.11–1.18, and up to a seventh or greater exacerbation (aHR 1.10, 95% CI 1.07–1.13.

The estimated life expectancy at birth in 1990 of 69.99 years was 3.5 years higher than the corresponding estimate based on the 1980 census. The gain in life expectancy averaged 3 years for ages 1-20 years, 2 years for ages 30-40 years, and 1-1.5 years for ages 45-65. The principal causes of general mortality were heart disease, accidents, malignant tumors, infectious intestinal diseases, and diabetes mellitus. The 5 principal causes of infant mortality were disorders arising in the perinatal period, infectious intestinal disorders, pneumonia and influenza, congenital anomalies, and nutritional deficiency disorders. Gains in life expectancy during the 1980s were significant because of the decline in infant mortality, but infant mortality levels remain high compared to those of other countries. Differentials in infant mortality rates in different states were significant, with 1990 rates ranging from 70/1000 in Oaxaca to 30 in the Federal District. The differentials in infant mortality rates were reflected in life expectancies. In the Federal District and the states of Nuevo Leon, Nayarit, and Tamaulipas, life expectancy exceeded the national average by 2-5 years. The proportion of deaths in the earliest age group that were not reported declined at the national level from around 20% in 1980 to around 10% in 1990. Census-based infant mortality estimates for 1990 were more reliable than those for 1980.

Being married may decrease the risk of severe infections, due to better social support and healthier lifestyle. Patients and methods: In this population-based case-control study, we identified all adult patients with a first-time pneumonia-related hospitalization between 1994 and 2008 in Northern Denmark. For each case, ten sex- and age-matched population controls were selected from Denmark's Civil Registration System. We performed conditional logistic regression analysis to estimate the odds ratios (ORs for pneumonia hospitalization among persons who were divorced, widowed, or never married, as compared with married persons, adjusting for age, sex, 19 different comorbidities, alcoholism-related conditions, immunosuppressant use, urbanization, and living with small children. Results: The study included 67,162 patients with a pneumonia-related hospitalization and 671,620 matched population controls. Compared with controls, the pneumonia patients were more likely to be divorced (10% versus 7% or never married (13% versus 11%. Divorced and never-married patients were much more likely to have previous diagnoses of alcoholism-related conditions (18% and 11%, respectively compared with married (3% and widowed (6% patients. The adjusted OR for pneumonia-related hospitalization was increased, at 1.29 (95% confidence interval [CI]: 1.25-1.33 among divorced; 1.15 (95% CI: 1.12-1.17 among widowed; and 1.33 (95% CI: 1.29-1.37 among never-married individuals as compared with those who were married. Conclusion: Married individuals have a decreased risk of being hospitalized with pneumonia compared with never-married, divorced, and widowed patients

    Full Text Available Here we investigated the role of the Nod/Rip2 pathway in host responses to Chlamydophila pneumoniae-induced pneumonia in mice. Rip2(-/- mice infected with C. pneumoniae exhibited impaired iNOS expression and NO production, and delayed neutrophil recruitment to the lungs. Levels of IL-6 and IFN-gamma levels as well as KC and MIP-2 levels in bronchoalveolar lavage fluid (BALF were significantly decreased in Rip2(-/- mice compared to wild-type (WT mice at day 3. Rip2(-/- mice showed significant delay in bacterial clearance from the lungs and developed more severe and chronic lung inflammation that continued even on day 35 and led to increased mortality, whereas WT mice cleared the bacterial load, recovered from acute pneumonia, and survived. Both Nod1(-/- and Nod2(-/- mice also showed delayed bacterial clearance, suggesting that C. pneumoniae is recognized by both of these intracellular receptors. Bone marrow chimera experiments demonstrated that Rip2 in BM-derived cells rather than non-hematopoietic stromal cells played a key role in host responses in the lungs and clearance of C. pneumoniae. Furthermore, adoptive transfer of WT macrophages intratracheally was able to rescue the bacterial clearance defect in Rip2(-/- mice. These results demonstrate that in addition to the TLR/MyD88 pathway, the Nod/Rip2 signaling pathway also plays a significant role in intracellular recognition, innate immune host responses, and ultimately has a decisive impact on clearance of C. pneumoniae from the lungs and survival of the infectious challenge.

    Full Text Available Mycoplasma pneumonia is common agent causing community acquired pneumonia in younger population. However, the course of illness is usually benign and is rarely associated with pulmonary complications. We report a 27 years old female patient with unilateral pneumonia followed by pleural effusion and adhesions on the same side. This potential source of infection should be considered in young patients where resolution of symptoms from pneumonia is delayed.

    Bacteremia, the presence of viable bacteria in the blood stream, is often associated with several clinical conditions. Bacteremia can lead to multiple organ failure if managed incorrectly, which makes providing suitable nutritional support vital for reducing bacteremia-associated mortality. In order to provide such information, we investigated the metabolic consequences of a Klebsiella pneumoniae (K. pneumoniae) infection in vivo by employing a combination of (1)H nuclear magnetic resonance spectroscopy and multivariate data analysis. K. pneumoniae was intravenously infused in rats; urine and plasma samples were collected at different time intervals. We found that K. pneumoniae-induced bacteremia stimulated glycolysis and the tricarboxylic acid cycle and also promoted oxidation of fatty acids and creatine phosphate to facilitate the energy-demanding host response. In addition, K. pneumoniae bacteremia also induced anti-endotoxin, anti-inflammatory and anti-oxidization responses in the host. Furthermore, bacteremia could cause a disturbance in the gut microbiotal functions as suggested by alterations in a range of amines and bacteria-host co-metabolites. Our results suggest that supplementation with glucose and a high-fat and choline-rich diet could ameliorate the burdens associated with bacteremia. Our research provides underlying pathological processes of bacteremia and a better understanding of the clinical and biochemical manifestations of bacteremia.

    A protective effect induced by bacterial preinfection upon a subsequent lethal influenza virus infection has been observed, but the underlying immune mechanisms have not yet been fully elucidated. In this study, we used a mouse model of Klebsiella pneumoniae preinfection to gain insight into how bacterial preinfection influences the subsequent lethal influenza virus infection. We found that K. pneumoniae preinfection significantly attenuated lung immune injury and decreased mortality during influenza virus infection, but K. pneumoniae-specific immunity was not involved in this cross-protection against influenza virus. K. pneumoniae preinfection limited NK cell expansion, which was involved in influenza-induced immune injury and death. Furthermore, K. pneumoniae preinfection could not control NK cell expansion and death during influenza virus infection in Rag1(-/-) mice, but adoptive transfer of T cells from wild-type mice was able to restore this protective effect. Our data suggest that the adaptive immune response activated by bacterial infection limits the excessive innate immune response induced by a subsequent influenza infection, ultimately protecting mice from death.

    Pneumonia caused by influenza A virus (IAV) can have devastating effects, resulting in respiratory failure and death. The idea that a new influenza pandemic might occur in the near future has triggered renewed interests in IAV infection. The receptor for advanced glycation end products (RAGE) is expressed on different cell types and plays a key role in diverse inflammatory processes. We here investigated the role of RAGE in the host response to IAV pneumonia using wild-type (wt) and RAGE deficient ((-/-)) mice. Whereas strong RAGE was constitutively expressed in the lungs of uninfected wt mice, in particular on endothelium, IAV pneumonia was associated with enhanced expression on endothelium and de novo expression on bronchial epithelium. Additionally, the high-affinity RAGE ligand high mobility group box 1 was upregulated during IAV pneumonia. RAGE(-/-) mice were relatively protected from IAV induced mortality and showed an improved viral clearance and enhanced cellular T cell response and activation of neutrophils. These data suggest that RAGE is detrimental during IAV pneumonia.

    Organ cultures of adult hamster trachea were used to evaluate the cytotoxic potential of cell fractions of Mycoplasma pneumoniae. Cytoplasm was essentially devoid of activity, whereas viable cells and membrane preparations, at a level of 25 μg of protein per ml, induced necrosis. Damage, as revealed by light and electron microscopy, included ciliostasis, vacuolization, loss of ciliated respiratory epithelial cells, disorganization, and a loss of polarity. Dose response data indicated that the speed and degree of cytotoxicity was directly related to the concentration of membranes. Doses of 30 to 60 μg of protein per ml could reduce relative ciliary activity to 20% of the control level within 4 days. Membranes prepared after freeze-thaw lysis of cells were almost twice as active as those isolated after a combination of osmotic and sonic shock. Membranes of M. fermentans were inactive, though both the FH and M129 strains of M. pneumoniae were toxic. These data indicate that the toxic factor responsible for M. pneumoniae may be located in the cell membrane. Images PMID:16558100

    Full Text Available A pneumonia necrosante é uma patologia grave que surge como complicação rara de pneumonia lobar. Quatro crianças na faixa etária entre dez e 28 meses foram hospitalizadas com pneumonia bacteriana aguda, evoluindo com toxemia, derrame pleural e insuficiência respiratória, respondendo insatisfatoriamente a antibioticoterapia e drenagem pleural. Todos os pacientes foram submetidos a tratamento cirúrgico para descorticação pulmonar e ressecção de tecido pulmonar necrosado. Complicações como fístulas broncopleurais ocorreram em dois pacientes, havendo óbito em um dos casos. Os autores concluem que a ressecção pulmonar de emergência é indicada quando a necrose pulmonar é diagnosticada em pacientes septicêmicos ou com fístula broncopleural de alto débito, visando a melhora do prognóstico dessas crianças, mesmo cientes de que o índice de morbimortalidade nesses casos é alto.Necrotizing pneumonia is a serious complication of lobar pneumonia. Four children aged between ten months and three years were admitted with acute bacteremic pneumonia and developed sepsis, pleural effusion, and respiratory distress despite adequate antibiotic treatment and chest tube drainage. Decortication and pulmonary resection were performed in all of them. The observed complications were bronchopleural fistula and one death. The emergency pulmonary resection is indicated when pulmonary necrosis is associated to sepsis and massive bronchopleural fistula. In such circumstances, morbidity and mortality are higher than in other conditions.

    The Th17 cytokines interleukin-17A (IL-17A), IL-17F, and IL-22 are critical for the lung immune response to a variety of bacterial pathogens, including Klebsiella pneumoniae. Th2 cytokine expression in the airways is a characteristic feature of asthma and allergic airway inflammation. The Th2 cytokines IL-4 and IL-13 diminish ex vivo and in vivo IL-17A protein expression by Th17 cells. To determine the effect of IL-4 and IL-13 on IL-17-dependent lung immune responses to acute bacterial infection, we developed a combined model in which allergic airway inflammation and lung IL-4 and IL-13 expression were induced by ovalbumin sensitization and challenge prior to acute lung infection with K. pneumoniae. We hypothesized that preexisting allergic airway inflammation decreases lung IL-17A expression and airway neutrophil recruitment in response to acute K. pneumoniae infection and thereby increases the lung K. pneumoniae burden. As hypothesized, we found that allergic airway inflammation decreased the number of K. pneumoniae-induced airway neutrophils and lung IL-17A, IL-17F, and IL-22 expression. Despite the marked reduction in postinfection airway neutrophilia and lung expression of Th17 cytokines, allergic airway inflammation significantly decreased the lung K. pneumoniae burden and postinfection mortality. We showed that the decreased lung K. pneumoniae burden was independent of IL-4, IL-5, and IL-17A and partially dependent on IL-13 and STAT6. Additionally, we demonstrated that the decreased lung K. pneumoniae burden associated with allergic airway inflammation was both neutrophil and CCL8 dependent. These findings suggest a novel role for CCL8 in lung antibacterial immunity against K. pneumoniae and suggest new mechanisms of orchestrating lung antibacterial immunity.

    Klebsiella species is the second most commonly isolated gram-negative organism in sepsis and a frequent causative pathogen in pneumonia. The receptor for advanced glycation end products (RAGE) is expressed on different cell types and plays a key role in diverse inflammatory responses. We here aimed to investigate the role of RAGE in the host response to Klebsiella (K.) pneumoniae pneumonia and intransally inoculated rage gene deficient (RAGE-/-) and normal wild-type (Wt) mice with K. pneumoniae. Klebsiella pneumonia resulted in an increased pulmonary expression of RAGE. Furthermore, the high-affinity RAGE ligand high mobility group box-1 was upregulated during K. pneumoniae pneumonia. RAGE deficiency impaired host defense as reflected by a worsened survival, increased bacterial outgrowth and dissemination in RAGE-/- mice. RAGE-/- neutrophils showed a diminished phagocytosing capacity of live K. pneumoniae in vitro. Relative to Wt mice, RAGE-/- mice demonstrated similar lung inflammation, and slightly elevated-if any-cytokine and chemokine levels and unchanged hepatocellular injury. In addition, RAGE-/- mice displayed an unaltered response to intranasally instilled Klebsiella lipopolysaccharide (LPS) with respect to pulmonary cell recruitment and local release of cytokines and chemokines. These data suggest that (endogenous) RAGE protects against K. pneumoniae pneumonia. Also, they demonstrate that RAGE contributes to an effective antibacterial defense during K. pneumoniae pneumonia, at least partly via its participation in the phagocytic properties of professional granulocytes. Additionally, our results indicate that RAGE is not essential for the induction of a local and systemic inflammatory response to either intact Klebsiella or Klebsiella LPS.

    Few comprehensive studies have searched for viruses and bacteria in children with community-acquired pneumonia (CAP). We identified 76 children hospitalized for pneumonia. Induced sputum samples were analysed for 18 viruses by antigen detection and PCR, and for six bacteria by culture and PCR. Viruses were found in 72% of samples, bacteria in 91%, and both in 66%. Rhinovirus (30%), human bocavirus (18%) and human metapneumovirus (14%) were the most commonly detected viruses. Two viruses were found in 22% of samples and three in 8%. The most common bacteria found were Streptococcus pneumoniae (50%), Haemophilus influenzae (38%), and Moraxella catarrhalis (28%). Rhinovirus-S. pneumoniae was the most commonly found combination of virus and bacterium (16%). All six children with treatment failure had both viruses and bacteria detected in the sputum. Otherwise, we found no special clinical characteristics in those with mixed viral-bacterial detections. With modern molecular diagnostic techniques, there are high rates of both viral and bacterial identification in childhood CAP. The clinical significance of mixed viral-bacterial infections remains unclear, although we found a potential association between them and treatment failure.

Prospective, open, and non-comparative trial with meropenem were done in patients with ventilator-associated or aspiration NP in 2 ICUs at HC - University of São Paulo. Etiologic investigation was done through bronchoalveolar lavage and blood cultures prior to study entry. Twenty-five (25 critically ill patients with NP were enrolled (mean age 40 years. Ventilator-acquired pneumonia was responsible for 76% of cases and aspiration NP for 24%. Specific etiologic agents were identified and considered to be clinically and temporally responsible for NP in 11 (44% patients. A. baumanii was responsible for 6 cases (55%, P. aeruginosa for 3 (27%, and S. aureus for 2 (18%. At completion of treatment, 19 patients (76% showed either cure (48% or improvement (28% after use of meropenem therapy. Mortality was 12% at the end of therapy (8% after excluding 1 non-evaluable patient. After 4 to 6 weeks of follow-up, 12 (48% patients had improved or been totally cured, and overall mortality was 24%. Clinical complications were observed in 11 patients (44%, with none of them definitely related to the study drug. Meropenem as monotherapy was effective and well-tolerated in most NP patients in our ICU. The low mortality rate in this study might have been due to first choice use of this drug. Controlled, drug comparative clinical trials are needed to support this preliminary observation.

    Hemorrhage remains as one of the top 3 obstetrics related causes of maternal mortality, with most deaths occurring within 24-48 hours of delivery. Although hemorrhage related maternal mortality has declined globally, it continues to be a vexing problem. More specifically, the developing world continue to shoulder a disproportionate share of hemorrhage related deaths (99%) compared with industrialized nations (1%). Given the often preventable nature of death from hemorrhage, the cornerstone of effective mortality reduction involves risk factor identification, quick diagnosis, and timely management. In this monograph we will review the epidemiology, etiology, and preventative measures related to maternal mortality from hemorrhage.

There is little epidemiological evidence from large population-based studies on risk factors for these infections and subsequent mortality in total hip arthroplasty (THA patients.Aim: To examine the risk factors of postoperative pneumonia and UTI after THA and their impact on survival.Patients and methods: We used the Danish Hip Arthroplasty Register to identify THAs due to osteoarthritis registered from 2000 to 2013. We collected data about comorbidities, mortality and infections in relation to primary hospitalization and potential predictive variables from administrative databases. Regression models were used to estimate associations between potential risk factors and infection, and subsequently, between infection and mortality.Results: In total 84,812 THAs were included. The cumulative incidence of pneumonia and UTI within 7 days of the primary procedure were 0.21 (95% confidence interval [CI]: 0.18–0.25 and 0.29 (95% CI: 0.26–0.33, respectively. Patient-related risk factors for infection were being 80 years or older, gender and a comorbidity burden at time of surgery.

Clinical features include acute onset of blanchable, annular, polycyclic, erythematous wheals with dusky or ecchymotic centers (target lesion-like. Pruritus in nearly all and edema on the face, hand and foot in the majority of cases are seen. Urticaria multiforme known as a cutaneous hypersensitivity reaction can often be misdiagnosed as erythema multiforme and serum-sickness-like reaction. Although the majority of cases have been related with viral or bacterial infections and drug use, the exact etiopathogenesis of the disease is yet unclear. Association of Mycoplasma pneumoniae infection and urticaria multiforme have been reported in only two cases in the literature. In this article, a total of four cases diagnosed as urticaria multiforme two of whom had clinical and serological proof of Mycoplasma pneumoniae infection has been presented, and diagnostic criteria, differential diagnosis, etiopathogenesis and treatment of urticaria multiforme have been reviewed.

    Full Text Available Abstract Background Patients hospitalized with community acquired pneumonia (CAP have a substantial risk of death, but there is evidence that adherence to certain processes of care, including antibiotic administration within 8 hours, can decrease this risk. Although national mortality data shows blacks have a substantially increased odds of death due to pneumonia as compared to whites previous studies of short-term mortality have found decreased mortality for blacks. Therefore we examined pneumonia-related processes of care and short-term mortality in a population of patients hospitalized with CAP. Methods We reviewed the records of all identified Medicare beneficiaries hospitalized for pneumonia between 10/1/1998 and 9/30/1999 at one of 101 Pennsylvania hospitals, and randomly selected 60 patients at each hospital for inclusion. We reviewed the medical records to gather process measures of quality, pneumonia severity and demographics. We used Medicare administrative data to identify 30-day mortality. Because only a small proportion of the study population was black, we included all 240 black patients and randomly selected 720 white patients matched on age and gender. We performed a resampling of the white patients 10 times. Results Males were 43% of the cohort, and the median age was 76 years. After controlling for potential confounders, blacks were less likely to receive antibiotics within 8 hours (odds ratio with 95% confidence interval 0.6, 0.4–0.97, but were as likely as whites to have blood cultures obtained prior to receiving antibiotics (0.7, 0.3–1.5, to have oxygenation assessed within 24 hours of presentation (1.6, 0.9–3.0, and to receive guideline concordant antibiotics (OR 0.9, 0.6–1.7. Black patients had a trend towards decreased 30-day mortality (0.4, 0.2 to 1.0. Conclusion Although blacks were less likely to receive optimal care, our findings are consistent with other studies that suggest better risk-adjusted survival

    Asthma is the most prevalent chronic disease in childhood. To study the actual prevalence and impact of undiagnosed childhood asthma in daily life (i.e. quality of life, participation in physical and school activities) we performed a survey in schoolchildren (aged 7-10 years) in the southern part of

    Full Text Available Abstract Background Recent studies suggest that the reported protective effects of statins (HMG-CoA reductase inhibitors against community-acquired pneumonia (CAP and sepsis in humans may be due to confounders and a healthy user-effect. To directly test whether statins are protective against Streptococcus pneumoniae, the leading cause of CAP, we examined the impact of prolonged oral simvastatin therapy at physiologically relevant doses in a mouse model of pneumococcal pneumonia. BALB/c mice were placed on rodent chow containing 0 mg/kg (control, 12 mg/kg (low simvastatin diet [LSD]; corresponds to 1.0 mg/kg/day, or 120 mg/kg (high simvastatin diet [HSD]; corresponds to 10 mg/kg/day simvastatin for four weeks, infected intratracheally with S. pneumoniae serotype 4 strain TIGR4, and sacrificed at 24, 36, or 42 h post-infection for assessment of lung histology, cytokine production, vascular leakage and edema, bacterial burden and bloodstream dissemination. Some mice received ampicillin at 12-h intervals beginning at 48 h post-infection and were monitored for survival. Immunoblots of homogenized lung samples was used to assess ICAM-1 production. Results Mice receiving HSD had reduced lung consolidation characterized by less macrophage and neutrophil infiltration and a significant reduction in the chemokines MCP-1 (P = 0.03 and KC (P = 0.02 and ICAM-1 in the lungs compared to control mice. HSD mice also had significantly lower bacterial titers in the blood at 36 (P = 0.007 and 42 (P = 0.03 hours post-infection versus controls. LSD had a more modest effect against S. pneumoniae but also resulted in reduced bacterial titers in the lungs and blood of mice after 42 h and a reduced number of infiltrated neutrophils. Neither LSD nor HSD mice had reduced mortality in a pneumonia model where mice received ampicillin 48 h after challenge. Conclusions Prolonged oral simvastatin therapy had a strong dose-dependent effect on protection

    Background: Community-acquired pneumonia is the seventh leading cause of death in Canada. Previous studies have shown reductions in both mortality rate and length of hospital stay with the use of guideline-concordant empiric therapy and standardized preprinted orders. Objectives: The primary objective was to determine adherence to the preprinted order for community-acquired pneumonia at the University Hospital of Northern British Columbia (UHNBC). The study also had the following secondary objectives: to assess the appropriateness of prescribing of levofloxacin in relation to institutional recommendations; to determine adherence with recent guidelines from the Infectious Diseases Society of America (IDSA) and the American Thoracic Society (ATS) for the treatment of community-acquired pneumonia; and to determine all-cause mortality, duration of IV antibiotic therapy, and length of stay for the various regimens reviewed. Methods: A retrospective observational chart review was conducted of patients with community-acquired pneumonia who were admitted between November 2007 and February 2008. Exclusion criteria were designed to eliminate patients who did not have this condition. Descriptive statistics were used to assess adherence with the preprinted order. Secondary outcomes were analyzed with the Pearson χ2 test, t tests, and analysis of variance. Results: In total, the charts for 113 patients were reviewed, and 58 patients were included in the study. The preprinted order for community-acquired pneumonia was used for 25 (43%) of the 58 patients; however, for only 4 (7%) of these admissions were all sections of the preprinted order used correctly. No statistically significant differences in length of stay were found for any of the antibiotic combinations assessed. However, the proportion of patients treated according to the IDSA–ATS guidelines was significantly greater when the preprinted order was used (p = 0.012). In addition, use of the preprinted order encouraged
