A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).
Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.

Fatal Serratia marcescens meningitis and myocarditis in a patient with an indwelling urinary catheter. (1/5242)Serratia marcescens is commonly isolated from the urine of patients with an indwelling urinary catheter and in the absence of symptoms is often regarded as a contaminant. A case of fatal Serratia marcescens septicaemia with meningitis, brain abscesses, and myocarditis discovered at necropsy is described. The patient was an 83 year old man with an indwelling urinary catheter who suffered from several chronic medical conditions and from whose urine Serratia marcescens was isolated at the time of catheterisation. Serratia marcescens can be a virulent pathogen in particular groups of patients and when assessing its significance in catheter urine specimens, consideration should be given to recognised risk factors such as old age, previous antibiotic treatment, and underlying chronic or debilitating disease, even in the absence of clinical symptoms.

Role of schools in the transmission of measles in rural Senegal: implications for measles control in developing countries. (2/5242)Patterns of measles transmission at school and at home were studied in 1995 in a rural area of Senegal with a high level of vaccination coverage. Among 209 case children with a median age of 8 years, there were no deaths, although the case fatality ratio has previously been 6-7% in this area. Forty percent of the case children had been vaccinated against measles; the proportion of vaccinated children was higher among secondary cases (47%) than among index cases (33%) (prevalence ratio = 1.36, 95% confidence interval (CI) 1.04-1.76). Vaccinated index cases may have been less infectious than unvaccinated index cases, since they produced fewer clinical cases among exposed children (relative risk = 0.55, 95% CI 0.29-1.04). The secondary attack rate was lower in the schools than in the homes (relative risk = 0.31, 95% CI 0.20-0.49). The school outbreaks were protracted, with 4-5 generations of cases being seen in the two larger schools. Vaccine efficacy was found to be 57% (95% CI -23 to 85) in the schools and 74% (95% CI 62-82) in the residential compounds. Measles infection resulted in a mean of 3.8 days of absenteeism per case, though this did not appear to have an impact on the children's grades. Among the index cases, 56% of children were probably infected by neighbors in the community, and 7% were probably infected at health centers, 13% outside the community, and 24% in one of the three schools which had outbreaks during the epidemic. However, most of the school-related cases occurred at the beginning and therefore contributed to the general propagation of the epidemic. To prevent school outbreaks, it may be necessary to require vaccination prior to school entry and to revaccinate children in individual schools upon detection of cases of measles. Multidose measles vaccination schedules will be necessary to control measles in developing countries. (+info)
Risk factors for nosocomial bloodstream infections due to Acinetobacter baumannii: a case-control study of adult burn patients. (3/5242)Risk factors for Acinetobacter baumannii bloodstream infection (BSI) were studied in patients with severe thermal injury in a burn intensive care unit where A. baumannii was endemic. Of 367 patients hospitalized for severe thermal injury during the study period, 29 patients with nosocomial A. baumannii BSI were identified (attack rate, 7.9%). Cases were compared with 58 matched controls without A. baumannii BSI. The overall mortality rate was 31% among cases and 14% among controls; only two deaths (7%) were considered directly related to A. baumannii BSI. Molecular typing of A. baumannii blood isolates by means of randomly amplified polymorphic DNA analysis and pulsed-field gel electrophoresis revealed the presence of three different strain types. Multivariate analysis showed that female gender (P = .027), total body surface area burn of > 50% (P = .016), prior nosocomial colonization with A. baumannii at a distant site (P = .0002), and use of hydrotherapy (P = .037) were independently associated with the acquisition of A. baumannii BSI in burn patients. These data underscore the need for effective infection control measures for this emerging nosocomial problem. (+info)
Infective endocarditis due to Staphylococcus aureus: 59 prospectively identified cases with follow-up. (4/5242)Fifty-nine consecutive patients with definite Staphylococcus aureus infective endocarditis (IE) by the Duke criteria were prospectively identified at our hospital over a 3-year period. Twenty-seven (45.8%) of the 59 patients had hospital-acquired S. aureus bacteremia. The presumed source of infection was an intravascular device in 50.8% of patients. Transthoracic echocardiography (TTE) revealed evidence of IE in 20 patients (33.9%), whereas transesophageal echocardiography (TEE) revealed evidence of IE in 48 patients (81.4%). The outcome for patients was strongly associated with echocardiographic findings: 13 (68.4%) of 19 patients with vegetations visualized by TTE had an embolic event or died of their infection vs. five (16.7%) of 30 patients whose vegetations were visualized only by TEE (P < .01). Most patients with S. aureus IE developed their infection as a consequence of a nosocomial or intravascular device-related infection. TEE established the diagnosis of S. aureus IE in many instances when TTE was nondiagnostic. Visualization of vegetations by TTE may provide prognostic information for patients with S. aureus IE.

Optimizing aminoglycoside therapy for nosocomial pneumonia caused by gram-negative bacteria. (5/5242)Nosocomial pneumonia is a notable cause of morbidity and mortality and leads to increases in lengths of hospital stays and institutional expenditures. Aminoglycosides are used to treat patients with these infections, but few data on the doses and schedules required to achieve optimal therapeutic outcomes exist. We analyzed aminoglycoside treatment data for 78 patients with nosocomial pneumonia to determine if optimization of aminoglycoside pharmacodynamic parameters results in a more rapid therapeutic response (defined by outcome and days to leukocyte count resolution and temperature resolution). Cox proportional hazards, Classification and Regression Tree (CART), and logistic regression analyses were applied to the data. By all analyses, the first measured maximum concentration of drug in serum (Cmax)/MIC predicted days to temperature resolution and the second measured Cmax/MIC predicted days to leukocyte count resolution. For days to temperature resolution and leukocyte count resolution, CART analyses produced breakpoints, with an 89% success rate at 7 days of therapy for a Cmax/MIC of > 4.7 and an 86% success rate at 7 days of therapy for a Cmax/MIC of > 4.5, respectively. Logistic regression analyses predicted a 90% probability of temperature resolution and leukocyte count resolution by day 7 if a Cmax/MIC of > or = 10 is achieved within the first 48 h of aminoglycoside therapy. Aggressive aminoglycoside dosing immediately followed by individualized pharmacokinetic monitoring would ensure that Cmax/MIC targets are achieved early in therapy. This would increase the probability of a rapid therapeutic response for pneumonia caused by gram-negative bacteria and potentially decreasing durations of parenteral antibiotic therapy, lengths of hospitalization, and institutional expenditures, a situation in which both the patient and the institution benefit.

Efficacy of sulbactam alone and in combination with ampicillin in nosocomial infections caused by multiresistant Acinetobacter baumannii. (6/5242)From March 1995 to March 1997, sulbactam was prospectively evaluated in patients with non-life-threatening multiresistant Acinetobacter baumannii infections. During this period, 47 patients were treated with sulbactam; of them, five were excluded because they had received < or =48 h of sulbactam therapy. A total of 42 patients, 27 males and 15 females with a mean age of 60+/-15 years, were finally evaluated. Infections were as follows: surgical wound, 19; tracheobronchitis, 12; urinary tract, 7; catheter-related bacteraemia, 2; and pneumonia, 2. Eighteen patients received intravenous sulbactam alone (1 g every 8 h) and 24 patients received intravenous sulbactam/ampicillin (1 g:2 g every 8 h) with no major adverse effects. Of the 42 patients, 39 improved or were cured and showed A. baumannii eradication and one patient had persistence of wound infection after 8 days of sulbactam/ampicillin requiring surgical debridement. Two patients died after 3 days of therapy (one of the deaths was attributable to A. baumannii infection). The in-vitro activity of the sulbactam/ampicillin combination was by virtue of the antimicrobial activity exhibited by sulbactam. Killing curves showed that sulbactam was bacteriostatic; no synergy was observed between ampicillin and sulbactam. Our results indicate that sulbactam may prove effective for non-life-threatening A. baumannii infections. Its role in the treatment of severe infections is unknown. However, the current formulation of sulbactam alone may allow its use at higher doses and provide new potential synergic combinations, particularly for those infections by A. baumannii resistant to imipenem.

Transmission dynamics of epidemic methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci in England and Wales. (7/5242)A simple epidemiological framework for the analysis of the transmission dynamics of hospital outbreaks of epidemic methicillin-resistant Staphylococcus aureus (EMRSA) and vancomycin-resistant enterococci (VRE) in hospitals in England and Wales is presented. Epidemic strains EMRSA-15 and EMRSA-16 are becoming endemic in hospitals in the United Kingdom, and theory predicts that EMRSA-15 and EMRSA-16 will reach respective endemic levels of 158 (95% confidence interval [CI], 143-173) and 116 (95% CI, 109-123) affected hospitals with stochastic fluctuations of up to 30 hospitals in each case. An epidemic of VRE is still at an early stage, and the incidence of hospitals newly affected by VRE is growing exponentially at a rate r=0.51/year (95% CI, 0.48-0.54). The likely impact of introducing surveillance policies if action is taken sufficiently early is estimated. Finally, the role of heterogeneity in hospital size is considered: "Super-spreader hospitals" may increase transmission by 40%-132% above the expected mean. (+info)
Serum is more suitable than whole blood for diagnosis of systemic candidiasis by nested PCR. (8/5242)PCR assays for the diagnosis of systemic candidiasis can be performed either on serum or on whole blood, but results obtained with the two kinds of samples have never been formally compared. Thus we designed a nested PCR assay in which five specific inner pairs of primers were used to amplify specific targets on the rRNA genes of Candida albicans, C. tropicalis, C. parapsilosis, C. krusei, and C. glabrata. In vitro, the lower limit of detection of each nested PCR assay was 1 fg of purified DNA from the corresponding Candida species. In rabbits with candidemia of 120 minutes' duration following intravenous (i.v.) injection of 10(8) CFU of C. albicans, the sensitivities of the PCR in serum and whole blood were not significantly different (93 versus 86%). In other rabbits, injected with only 10(5) CFU of C. albicans, detection of candidemia by culture was possible for only 1 min, whereas DNA could be detected by PCR in whole blood and in serum for 15 and 150 min, respectively. PCR was more often positive in serum than in whole blood in 40 culture-negative samples (27 versus 7%; P < 0.05%). Lastly, experiments with rabbits injected i.v. with 20 or 200 microgram of purified C. albicans DNA showed that PCRs were positive in serum from 30 to at least 120 min after injection, suggesting that the clearance of free DNA is slow. These results suggest that serum is the sample of choice, which should be used preferentially over whole blood for the diagnosis of systemic candidiasis by PCR. (+info)

Epidemiology and Diagnosis of Health Care-Associated Infections in the NICU | From the American Academy of Pediatrics |...
Newborn infants hospitalized in a NICU have host factors that not only make them more vulnerable to acquisition of health care-associated infections but also increase their risk of developing more serious illnesses. Whether an infant is born preterm or at term, many components of their innate and adaptive immune systems exhibit diminished function when compared with older children and adults. Infants with birth weights less than1500 g (very low birth weight) have rates of health care-associated infections 3 times higher than those who weigh greater than 1500 g at birth. However, the increased susceptibility to infection in infants of very low birth weight is multifactorial and related to both the developmental deficiencies in the innate and adaptive immune systems and a greater likelihood of a critical illness requiring invasive monitoring and procedures. Furthermore, the immunologic deficiencies can be exacerbated by the critical nature of many of the illnesses affecting newborn ...
Computers in Neonatology: Haas JP
BACKGROUND: Pneumonia surveillance is difficult and time-consuming. The definition is complicated, and there are many opportunities for subjectivity in determining infection status. OBJECTIVE: To compare traditional infection control professional (ICP) surveillance for pneumonia among neonatal intensive care unit (NICU) patients with computerized surveillance of chest x-ray reports using an automated detection system based on a natural language processor. METHODS: This system evaluated chest x-rays from 2 NICUs over a 2-year period. It flagged x-rays indicative of pneumonia according to rules derived from the National Nosocomial Infection Surveillance System definition as applied to radiology reports. Data from the automated system were compared with pneumonia data collected prospectively by an ICP. RESULTS: Sensitivity of the computerized surveillance in NICU 1 was 71%, and specificity was 99.8%. The positive predictive value was 7.9%, and the negative predictive value (NPV) was >99%. Data from ...

CDC: Health Care-associated Infection Reaches All Time High
The incidence, mortality, and medical care costs of Clostridium difficile (C. difficile), a common and sometimes fatal health care-associated infection, are all at historic highs, according to a report released yesterday by the Centers for Disease Control and Prevention (CDC). The report shows that C. difficile is not just a problem in hospitals-it is a patient safety issue in all types of medical facilities, including nursing homes, physician offices, and outpatient facilities. C. difficile causes diarrhea linked to 14,000 American deaths each year. Almost half of the infections occur in people younger than 65, but more than 90% of deaths occur in people 65 and older. About 25% of C. difficile infections first show symptoms in hospital patients; 75% first show in nursing home patients or in people recently cared for in physician offices and clinics.. To help reduce the spread of C. difficile, CDC provides guidelines and tools to the health care community, including a podcast on 6 steps to ...

CDPH Releases Reports on Healthcare-Associated Infections -Vaccination Rates
The California Department of Public Health (CDPH) released two annual reports recently. The reports provide information about healthcare-associated infections (HAI) and influenza vaccination rates among health care providers.. While California hospitals have made progress in preventing healthcare-associated infections, HAIs continue to be a significant public health issue in the state. In 2015, hospitals reported 19,847 healthcare-associated infections to CDPH. From 2014 to 2015, 56 hospitals demonstrated significant improvement in preventing one or more HAI type. Hospitals are making progress in preventing HAI with the exception of C. difficile diarrheal infections (CDI), which increased 8 percent since 2011. CDPH offered infection-prevention assistance to 73 hospitals with high infection rates.. The departments influenza vaccination report indicates that vaccination rates among health care providers have improved in the past five years. Since 2011, vaccination rates increased 21 percent for ...
Healthcare-Associated Infections | State Public Health | ASTHO
As a significant cause of death, healthcare-associated infections (HAI) are a critical challenge to public health in the United States. At any given time, about 1 in 25 patients has an infection while receiving care in U.S. hospitals. These infections result in up to $33 billion in excess medical costs every year.. ASTHO is working with HHS, CDC, and the Keystone Center to determine the role of state health officials in decreasing and preventing HAIs, specifically addressing priorities, challenges, and solutions at the state and regional level. In March 2011, ASTHO and CDC jointly released the HAI policy toolkit -Eliminating Healthcare-Associated Infections: State Policy Options. The companion report, Policies for Eliminating Healthcare-Associated Infections: Lessons from State Stakeholder Engagement was released in January 2012. ASTHO also maintains situational awareness on HAI-related policies and initiatives, shares this information with members, and represents the state health agency ...
Avicenna Journal of Clinical Microbiology and Infection - Prevalence of Nosocomial Infection in Different Wards of Ghaem...
Nosocomial infection is one of the leading problems in the health system, therefore it is directly related to increased costs and hospitalization time. The prevalence rate of nosocomial infection in terms of geographic region, type of hospital, the patient, and the calculating method even in various regions of the country is different. According to the WHO report, the prevalence of the nosocomial infection in developed countries is below 5%, however, in developing countries, this rate is different (6). In this study, the incidence of nosocomial infection is about 1.1%, which is not comparable to the global statistics in developing countries; a study conducted in Benin, in 2012, patients from the same ward were studied in the same day in each hospital for real estimation of nosocomial infection, and data showed that the prevalence rate of nosocomial infection was 19.1% (10). Other studies, especially from developing countries, reported the prevalence rate of 13.9% - 17.9% (11, 12). The prevalence ...

OBJECTIVE: To describe the epidemiology of infections in intensive care units (ICUs), whether present at admission or acquired during the stay. METHODS: Prospective data collection lasting 6 months in 71 Italian adult ICUs. Patients were screened for infections and risk factors at ICU admission and daily during their stay. MAIN RESULTS: Out of 9,493 consecutive patients admitted to the 71 ICUs, 11.6% had a community-acquired infection, 7.4% a hospital-acquired infection, and 11.4% an ICU-acquired infection. The risk curve of acquiring infection in the ICU was higher in patients who entered without infection than in those already infected (log-rank test, p , .0001; at 15 days, 44.0% vs. 34.6%). Hospital mortality (27.8% overall) was higher in patients admitted with infection than in those who acquired infection in the ICU (45.0% vs. 32.4%, p , .0001). Although the presence of infection per se did not influence mortality, the conditions of severe sepsis and septic shock were strong prognostic ...
Infections Acquired in Health Care Facilities | Harrisons Principles of Internal Medicine, 19e | AccessMedicine | McGraw-Hill...
The costs of hospital-acquired (nosocomial) and other health care-associated infections are great. These infections have affected as many as 1.7 million patients at a cost of ~$28-33 billion and 99,000 lives in U.S. hospitals annually. Although efforts to lower infection risks have been challenged by the numbers of immunocompromised patients, antibiotic-resistant bacteria, fungal and viral superinfections, and invasive devices and procedures, a prevailing viewpoint-often termed zero tolerance-is that almost all health care-associated infections should be avoidable with strict application of evidence-based prevention guidelines (Table 168-1). In fact, rates of device-related infections-historically, the largest drivers of risk-have fallen steadily over the past few years. Unfortunately, at the same time, antimicrobial-resistant pathogens have risen in number and are estimated to contribute to ~23,000 deaths in and outside of hospitals annually. This chapter reviews health care-associated and ...

Health Experts Establish Targets to Improve Hospital Antibiotic Prescribing | The Pew Charitable Trusts
The targets outlined in this report are based on data collected by the CDCs Emerging Infections Program (EIP) through its Healthcare-Associated Infections Community Interface (HAIC) activity. The EIP-a network of 10 state health departments and their academic and other partners-conducts population-based surveillance of health care-associated infections and antimicrobial-resistant pathogens. It also undertakes special projects to define the epidemiology of health care-associated infections and antimicrobial use in hospitals and nursing homes. The EIPs HAIC began collecting data on antimicrobial use in hospitals in 2011. In collaboration with the EIP network, the CDC conducted a survey to measure the amount of antibiotic use in hospitals. This survey found that about half of all patients were receiving one or more antibiotics and that use of broad-spectrum antibiotics was high.27 The results suggested that there is room to reduce antibiotic use in inpatient settings. However, the survey did not ...

Cholesterol and Serum Albumin Levels as Predictors of Cross Infection, Death, and Length of Hospital Stay
HYPOTHESIS:The levels of cholesterol, its fractions (high-density lipoprotein cholesterol [HDL-C] and low-density lipoprotein cholesterol [LDL-C]), and serum albumin reflect nutritional status and are related to in-hospital death, nosocomial infection, and length of stay in the hospital. DESIGN:A prospective cohort study of hospitalized patients. SETTING:The Service of General Surgery of a tertiary hospital. PATIENTS:A consecutive series of 2989 patients admitted for more than 1 day. MAIN OUTCOME MEASURES:Nosocomial infection, in-hospital death, and length of stay. RESULTS:During follow-up, 62 (2%) of the patients died, 382 (13%) developed a nosocomial infection, and 257 (9%) developed a surgical site infection. Serum albumin (lowest quintile vs highest quintile: adjusted odds ratio [OR], 1.9; 95% confidence interval, 1.2-2.9) and HDL-C (lowest quintile vs highest quintile: OR, 2.0; 95% confidence interval, 1.3-3.0) levels showed an inverse and highly significant relationship with nosocomial ...
Chlorhexidine bathing and health care-associated infections among adult intensive care patients: a systematic review and meta...
This meta-analysis presents a summary of the estimated benefit of CHG bathing to prevent infection in the ICU. CHG bathing was most effective for the prevention of CLABSI among ICU patients, demonstrating a 56% reduction. However, the magnitude of benefit is affected by the underlying risk of CLABSI among ICU populations. Even among an average risk group of five CLABSI per 1000 central-line-days, 360 patients will need to be bathed with CHG to prevent a single event. If the underlying risk of CLABSI is only 1 per 1000 central-line-days than the NNT increases to 1780. Effectiveness was also shown for reducing MRSA colonisation and MRSA bacteraemia. However, even among average baseline-risk populations, the NNT is approximately 600 and 2800, respectively. Because of varying study designs (before-and-after versus randomised crossover trials), there remains uncertainty in the effectiveness of CHG-B to prevent other infections among adults in the ICU.. Previous reviews of daily CHG bathing to reduce ...

Investigating the Impact of the Nursing Practice Environment (NPE) on by Kristen A. Cribbs
Background: Health care-associated infections, resulting from treatment received for medical or surgical conditions in a health care setting, represent a critical public health and patient safety issue, exacting substantial medical, social, and economic costs. The costliest among the leading causes of preventable health care-associated infections is central-line associated bloodstream infections (CLABSI), to which older adults (age 65 years and older) are particularly susceptible, especially during intensive care unit (ICU) stays. A rich body of research has empirically linked the quality of the nursing practice environment (NPE) in hospitals to both positive and negative patient outcomes; yet, surprisingly few studies have sought to examine relations between the hospital NPE and older adult CLABSI outcomes. This study aimed to fill this gap through analysis of de-identified data from the 2011 national Prevention of Nosocomial Infections and Cost-Effectiveness Refined (PNICER) study, provided by the

The point prevalence survey of healthcare-associated infections (HAIs) and antimicrobial use organized by the European Centre for Disease Prevention and Control (ECDC-PPS) and the Global Point Prevalence Survey of antimicrobial consumption (Global-PPS) were simultaneously performed in Belgian acute care hospitals in 2017. Belgian acute care hospitals were invited to participate in either the ECDC or Global-PPS. Hospital/ward/patient-level data were collected between September-December 2017. All patients present in the wards at 8 a.m. on the day of the PPS were included. The data of the ECDC and Global-PPS on antimicrobial consumption were pooled. Detailed data on HAIs were analysed for ECDC-PPS. Overall, 110 Belgian acute care hospital sites participated in the ECDC and Global-PPS (countrywide participation rate: 81.4%, 28,007 patients). Overall, a crude prevalence of patients with at least one antimicrobial of 27.1% (95% confidence interval (CI) 26.5-27.6%) was found. The most frequently reported
Improving Oral Care to Reduce Hospital-Acquired Pneumonia (HAP) in the Acute Neurologically Impaired Adult - Full Text View -...
Overview Problem: Hospital-acquired pneumonia (HAP) is the second most common nosocomial infection and is a significant cause of morbidity and mortality. In the surgical population, HAP is associated with a 55% increase in length of stay and increased costs of approximately $31,000.00 per case. Neurologically impaired patients (those with brain injury causing alterations in mental status, immobility, impaired swallowing and cough, and increased risk of aspiration) are particularly vulnerable to HAP. HAP negatively impacts patient comfort and satisfaction, increases costs associated with diagnostic tests and treatments, increases risk for sepsis, and potential for higher level of care. It is estimated 95% of care-dependent patients on the Royal Columbian Hospital (RCH) neuroscience unit acquire HAP during their stay.. Gap: Research studies have shown improving oral hygiene in critical care, neuroscience intensive care units and cardiac surgery reduces the incidence of HAP. However, in the acutely ...
Healthcare-Associated Infections | IHI - Institute for Healthcare Improvement
Healthcare-associated infections (HAIs) can be serious and even deadly for patients. Those who access the health care system for illness or injury are expecting care and treatment, not additional illness and complications, yet the Centers for Disease Control and Prevention estimates that 1 in 20 hospitalized patients develop an HAI. Treatment of HAIs can be difficult and may last for years, especially when the organism is resistant to multiple antibiotics. In addition to the human burden, excess costs are incurred across the health care system and many patients and payors are no longer willing to accept these avoidable costs.. Transmission of organisms that cause HAIs can occur in many ways: caregiver-to-patient, environment-to-patient, or patient-to-patient. Programs that have been successful in reducing HAIs have made this a strategic imperative and generally focused on improving multiple interventions, such as hand hygiene, use of contact and other precautions, active screening, and robust ...
Hospital-Acquired Infections to be Addressed | Imaging Technology News
David B. Nash, M.D., MBA, FACP and editor of the American Journal of Medical Quality will unveil a groundbreaking supplement with three peer-reviewed articles about hospital-acquired infections in the National Press Club (Murrow Room), 529 14th Street, NW, Washington, DC on November 20, from 10 a.m. to 11 a.m. Two of the studies confront the issue of blaming patient characteristics (age, risk factors, severity of illness) for higher infection rates - instead of a hospitals processes of care (hand washing, timeliness of pre-surgical antibiotics, elevation of pneumonia patients, proper placement of IV tubes). The third article highlights one hospitals infection reduction efforts, which demonstrate that the costs of treating a hospital-acquired infection can outstrip the payment system - in essence creating a lose-lose-lose situation for patients, hospitals and payers.. Hospital-acquired infections are an important issue which Congress (the House Subcommittee on Oversight and Investigations) ...

Health Care-Associated Infections
Vascular device-related infection is suspected on the basis of the appearance of the catheter site or the presence of fever or bacteremia without another source in patients with vascular catheters. The diagnosis is confirmed by the recovery of the same species of microorganism from peripheral-blood cultures (preferably two cultures drawn from peripheral veins by separate venipunctures) and from semiquantitative or quantitative cultures of the vascular catheter tip. Less commonly used diagnostic measures include differential time to positivity (,2 h) for blood drawn through the vascular access device compared with a sample from a peripheral vein or differences in quantitative cultures (a 5- to 10-fold or greater step-up) for blood samples drawn simultaneously from a peripheral vein and from a CVC.When infusionrelated sepsis is considered (e.g., because of the abrupt onset of fever or shock temporally related to infusion therapy), a sample of the infusate or blood product should be retained for ...

Study highlights serious problem of hospital-acquired infections in Africa - The Cleanzine
Study highlights serious problem of hospital-acquired infections in Africa. Research funded by the Wellcome Trust has highlighted the scale of the problem of hospital-acquired infections in sub-Saharan Africa. The study, published today in the Lancet, suggests that bloodstream infections acquired while in care might contribute to one in every 20 deaths that occur in children in hospitals in the region.. The issue of HAIs is well recognised in high-income countries, with major initiatives promoting cleanliness among hospital staff and visitors. However, despite many African hospitals being severely overcrowded, and suffering frequent shortages of basic supplies such as running water and clean linen, virtually no data exist on the number of hospital-acquired infections in the region.. The conditions in African hospitals are often poor, and it is very likely that these environments lead to considerable amounts of sickness among patients who are already debilitated by their primary illness, ...

OBJECTIVES: Surveillance is a key component of any control strategy for healthcare-associated infections (HAIs) and antimicrobial resistance (AMR), and public availability of methodologic aspects is crucial for the interpretation of the data. We sought to systematically review publicly available information for HAIs and/or AMR surveillance systems organized by public institutions or scientific societies in European countries. METHODS: A systematic review of scientific and grey literature following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was performed. Information on HAIs and/or AMR surveillance systems published until 31 October 2016 were included. RESULTS: A total of 112 surveillance systems were detected; 56 from 20 countries were finally included. Most exclusions were due to lack of publicly available information. Regarding AMR, the most frequent indicator was the proportion of resistant isolates (27 of 34 providing information, 79.42%); only ...

The first nationwide estimates of the burden of invasive MRSA were derived from ABCs; in 2005, ≈94,000 cases and ≈18,000 deaths were attributed to invasive MRSA (16). Most (≈84%) infections were health care-associated-either hospital-onset (culture obtained ,3 days after admission) or health care-associated community-onset (culture obtained from outpatient or within 3 calendar days after admission from a patient with a health care-associated risk factor, which include presence of a central venous catheter within 2 days before MRSA culture or history of surgery, hospitalization, dialysis, or residence of long-term care facility in the 12 months preceding culture date). The prominence of health care-associated community-onset infections was newly brought to light by the ABCs network (16). This report led to increased awareness of MRSA infections, and prevention of health care-associated MRSA became a goal for public health agencies and policy makers (17-19). ABCs documented a 54% decline in ...

A Prospective Study of Nosocomial Infection in a Neonatal ICU (NICU) | American Academy of Pediatrics
A prospective study of nosocomial sepsis was performed in the NICU of Surgiscope Pvt. Hospital to determine the organisms causing nosocomial infection in neonates and their resistance patterns; also studied were risk factors, clinical presentation, hematologic parameters, and outcomes over a 12-month period. A total of 363 neonates were admitted to the ICU. A total of 250 blood samples were sent for culture and sensitivity testing in suspicious cases of nosocomial infection. All patients were on antibiotics. Of these, 36.8% (92 of 250) had a positive result on culture. Isolated bacteria were mostly gram-negative bacilli (80.43%) with a marked predominance of Klebsiella (n = 32 [43.2%]) followed by Escherichia coli (n = 18 [24.32%]), Pseudomonas (n = 16 [21.62%]), and acinetobacter (n = 5 [6.75%]). Resistance to gentamicin was 100% for all organisms. Resistance to amikacin was 100% for E coli, Pseudomonas, and acinetobacter and 40% for Klebsiella. Resistance of these gram-negative rods ranged ...

- The standard neutralization assay cannot differentiate between serotype-specific and serotype cross-reactive antibodies in patients early after infection, leading to an overestimation of the long-term serotype-specific protection of an antibody response. (frontiersin.org)
- To better define the specificity of polyclonal antibodies during disease and after recovery, longitudinal samples from patients with primary or secondary DENV-2 infection were collected over a period of 1 year. (frontiersin.org)
- We found that serotype cross-reactive antibodies peaked 3 weeks after infection and subsided within 1 year. (frontiersin.org)

- The results showed that H7N9 infection and immunization with inactivated vaccine resulted in potent induction of hemagglutination-inhibition (HI), virus neutralization (VN) and HA-binding antibodies, whereas Newcastle disease virus (NDV)-vectored H7N9 vaccine induced marginal HI and VN titers but high levels of HA-binding antibody. (flu.org.cn)
- In addition, H7N9 infection and immunization induced stalk-specific antibodies in na?ve chickens and these antibodies recognized different epitopes in the stalk. (flu.org.cn)
- Virus infection and immunization with inactivated vaccine elicited antibodies cross-reactive with both group 1 and group 2 HAs, while antibodies induced by NDV-H7N9 vaccination showed a narrower cross-reactivity within group 2. (flu.org.cn)
- Moreover, only homologous neutralizing activity of the sera against H7N9 virus was observed, and cross-binding antibodies did not show heterosubtypic neutralizing activity. (flu.org.cn)
- Our results indicated that cross-group binding but non-neutralizing antibodies primarily targeting the stalk can be induced by natural H7N9 infection and immunization with inactivated vaccine in na?ve chickens. (flu.org.cn)
