    Full Text Available Kari S Anderson, Victoria M Mullally, Linda M Fredrick, Andrew L CampbellAbbott Laboratories, Abbott Park, IL, USAAbstract: Respiratory syncytial virus (RSV is a significant cause of morbidity in high-risk infants. Palivizumab is proven to prevent serious RSV disease, but compliance with prophylaxis (monthly doses during the RSV season is essential to ensure protection. We invited 453 pediatricians to participate in a survey to identify their perspectives of barriers to compliance and interventions to improve compliance with palivizumab prophylaxis schedules. One hundred physicians from five continents completed the survey, identifying caregiver inconvenience, distance to clinic, cost of prophylaxis, and lack of understanding of the severity of RSV as the most common reasons for noncompliance. They recommended provision of educational materials about RSV, reminders from hospital or clinic, and administration of prophylaxis at home to increase compliance. Globally, physicians recognize several obstacles to prophylaxis compliance. This survey suggests that focused proactive interventions such as empowering caregivers with educational materials and reducing caregiver inconvenience may be instrumental to increase compliance.Keywords: medication adherence, respiratory syncytial virus infections, infant, premature, immunization, passive

    Full Text Available Prospective cohort studies show that Down’s syndrome (DS is an independent risk factor for hospitalization for RSV bronchiolitis. It is unknown whether this observation has been translated into specific management for DS children. The primary goal was to assess the knowledge of healthcare providers in the European Union about RSV infection in DS children and to determine whether it influenced the implementation of prophylaxis. DS caregivers were surveyed using a standardized questionnaire, and country-specific guidelines were obtained. Fifty-three caregivers participated. Thirty-nine (86.7% had knowledge of the increased risk of severe RSV infection in DS children, and 30 (71.4% graded that it was important to have a statement on the use of RSV prophylaxis in existing guidelines. Twenty-eight participants had a local DS guideline; hard copies of twelve unique guidelines were obtained. Only one (8.3% contained a statement on RSV prophylaxis for DS, and five considered such a statement for the next version. Conclusion. Most pediatricians had knowledge that DS children have an increased risk of severe RSV infection. Despite the lack of a specific RSV prophylaxis trial in DS, they felt that a statement on RSV prophylaxis in DS guidelines was important, but this was rarely present in current guidelines.

    The Standards Committee of the Spanish Neonatology Society (SENeo) considers that the new document from the American Academy of Pediatrics, including recommendations for palivizumab use to prevent serious infections produced by the Respiratory Syncytial Virus (RSV), provides no new scientific evidence which would justify the modification of the current recommendations of the SENeo. However, some adjustments to the criteria of the existing recommendations are proposed to reduce the cost of the drug by its correct and judicious management.

    The aim of this study was to compare inpatient outcomes and costs for children with respiratory syncytial virus and congenital heart disease before and after the change in management guidelines for respiratory syncytial virus prophylaxis. Hospital discharge data from the Vizient (formerly University HealthSystem Consortium) were queried from October 2012 to June 2014 (Era 1) and July 2014 to April 2016 (Era 2) for patients aged Disease (ICD)-9 or ICD-10 code for congenital heart disease (745-747.49, Q20.0-Q26.4) and a primary or secondary admitting diagnosis of respiratory syncytial virus infection (079.6, J20.5), acute bronchiolitis due to respiratory syncytial virus (466.11, J21.0) or respiratory syncytial virus pneumonia (480.1, J12.1). This study is a review of a national administrative discharge database. Respiratory syncytial virus admissions were identified in 1269 patients aged congenital heart disease, with 644 patients in Era 1 and 625 in Era 2. Patients 0-12 months old represented 83% of admissions. Prior to 2014, children aged 0-24 months with congenital heart disease were eligible to receive respiratory syncytial virus prophylaxis. Updated guidelines, published in 2014, restricted the recommendation to administer palivizumab respiratory syncytial virus prophylaxis to children with congenital heart disease only if they are ≤12 months old. The outcome measures are hospital length of stay, ICU admission rate, mortality, and direct costs. There was no change in length of stay, ICU admission rate, in-hospital mortality, or direct costs for children 13-24 months old with congenital heart disease after the change in guidelines. There were no deaths in 13-24 month olds, regardless of era. Our findings provide additional support for the new guideline recommendations to provide respiratory syncytial virus prophylaxis only for children ≤12 months old with congenital heart disease. © 2018 Wiley Periodicals, Inc.

    2013-01-01

    Full Text Available Introduction. Respiratory syncytial virus (RSV is one of the main causes of lower respiratory tract infections (LRTI in infancy. In certain categories of children the risk of development of potentially lethal severe forms of the disease requiring hospitalization, treatment within resuscitation departments and use of artificial pulmonary ventilation is significantly higher than in any other category. Palivizumab is used to prevent RSV infection in such children; its high efficacy and tolerance were proved by numerous clinical trials. The aim of this study is to assess use of palivizumab for preventing the RSV-associated LRTI in children from the groups of high risk of severe course of this pathology from a clinical economic point of view in the course of a regular stage of RSV infection immune prevention program realized in Moscow in the season of 2012/2013. Materials and methods. The study involved detailed analysis of results of LRTI immune prevention with palivizumab in a sample of 189 case report forms containing information on the children who had received 3-5 injections of the drug. The estimated number of hospitalizations and deaths in this group of children in the absence of immune prevention was calculated in the model on the basis of results of the previously conducted studies of the RSV-associated LRTI course. The authors also calculated expenses on this group of children in the presence and absence of palivizumab immune prevention, expenses per 1 disability-adjusted life year and averted economic damage due to infantile mortality increase. Results. Use of palivizumab in the group under study has possibly prevented 39 hospitalizations, including 13 hospitalizations with medical care rendering at resuscitation and intensive care units, and 1 death. Immune prevention expenses in the group under study equaled to 33,518,514.60 rubles, whereas the estimated expenses in the absence of immune prevention equaled to 1,698,103.90 rubles. Cost

    Full Text Available Infection with respiratory syncytial virus (RSV is one of the major causes globally of childhood respiratory morbidity and hospitalization. Palivizumab, a humanized monoclonal antibody, has been recommended for high risk infants to prevent severe RSV-associated respiratory illness. This recommendation is based on evidence of efficacy when used under clinical trial conditions. However the real-world effectiveness of palivizumab outside of clinical trials among different patient populations is not well established. We performed a systematic review focusing on postlicensure observational studies of the protective effect of palivizumab prophylaxis for reducing RSV-associated hospitalizations in infants and children at high risk of severe infection. We searched studies published in English between 1 January 1999 and August 2013 and identified 420 articles, of which 20 met the inclusion criteria. This review supports the recommended use of palivizumab for reducing RSV-associated hospitalization rates in premature infants born at gestational age < 33 weeks and in children with chronic lung and heart diseases. Data are limited to allow commenting on the protective effect of palivizumab among other high risk children, including those with Down syndrome, cystic fibrosis, and haematological malignancy, indicating further research is warranted in these groups.

    Full Text Available The epidemiologic data on RSV infection prevalence in the Russian Federation and its impact on respiratory morbidity in the pediatric population are limited. This article provides the analysis of results of a prospective, multicenter, observational cohort study. The study was conducted in 9 centers in the Russian Federation — in Moscow, St. Petersburg, and Tomsk. Children less than 2 years of age were included. It was found that during the season of high RSV morbidity RSV is found in 38 % of children hospitalized for lower respiratory tract infections; mean hospitalisation duration in children with severe RSV infection was over 1 week. Usually the duration of hospitalization was associated with disease severity and requirements for healthcare resources and oxygen supplementation. Moreover, in the Russian Federation the hospital length of stay in patients with RSV infection depended on the type of medical insurance. It was demonstrated that RSV infection caused severe respiratory failure in some infants less than 1 year of age and, therefore, was a substantial burden for the system of hospital medical care in the Russian Federation. Prophylaxis of severe RSV infection in high-risk groups of children during the might reduce the need for hospitalization.

    The most effective way to control RSV infection would be the development of an expedient and safe vaccine. Subunit vaccines, live attenuated RSV vaccines, plasmid DNA vaccines have been tested either in human or in mouse models without reaching the ultimate goal of efficacy and safety, at least in humans. Viruses such as adenovirus, sendai virus, measles virus were also used as vectors for the generation of RSV vaccines with promising results in animal models. Recent patents describe new techniques for the generation of candidate vaccines. These patents include virus like particles as vaccine platforms, recombinant RSVs or modified RSV F protein as component of the vaccine. Despite the number of the candidate vaccines, the new RSV vaccines should overcome many obstacles before being established as effective vaccines for the control of RSV infections especially for the young infants who are more susceptible to the virus.

    Full Text Available Respiratory syncytial virus (RSV is the leading cause of pediatric viral respiratory tract infections. Neither vaccine nor effective antiviral therapy is available to prevent and treat RSV infection. Palivizumab, a humanized monoclonal antibody, is the only product approved to prevent serious RSV infection, but its high cost is prohibitive in low-income countries. Here, we aimed to identify an effective, safe, and affordable antiviral agent for pre-exposure prophylaxis (PrEP of RSV infection in children at high risk. We found that maleic anhydride (ML-modified human serum albumin (HSA, designated ML-HSA, exhibited potent antiviral activity against RSV and that the percentages of the modified lysines and arginies in ML- are correlated with such anti-RSV activity. ML-HSA inhibited RSV entry and replication by interacting with viral G protein and blocking RSV attachment to the target cells, while ML-HAS neither bound to F protein, nor inhibited F protein-mediated membrane fusion. Intranasal administration of ML-HSA before RSV infection resulted in significant decrease of the viral titers in the lungs of mice. ML-HSA shows promise for further development into an effective, safe, affordable, and easy-to-use intranasal regimen for pre-exposure prophylaxis of RSV infection in children at high risk in both low- and high-income countries.

    Full Text Available Abstract Motavizumab (MEDI-524 is a monoclonal antibody with enhanced neutralizing activity against RSV. In mice, motavizumab suppressed RSV replication which resulted in significant reduction of clinical parameters of disease severity. We evaluated the effect of motavizumab on the local and systemic immune response induced by RSV in the mouse model. Balb/c mice were intranasally inoculated with 106.5 PFU RSV A2 or medium. Motavizumab was given once intraperitoneally (1.25 mg/mouse as prophylaxis, 24 h before virus inoculation. Bronchoalveolar lavage (BAL and serum samples were obtained at days 1, 5 (acute and 28 (long-term post inoculation and analyzed with a multiplex assay (Beadlyte Upstate, NY for simultaneous quantitation of 18 cytokines: IL-1α, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, KC (similar to human IL-8, IL-10, IL-12p40, IL-12p70, IL-13, IL-17, TNF-α, MCP-1, RANTES, IFN-γ and GM-CSF.

    At the present time about two million people, one third of the Earth's population, are carriers of tuberculosis agent. Though tuberculosis is curable disease, it continues to take away lives of about 4400 persons; most of them are young and are in the most productive age. The most active incidence rate of tuberculosis occurs in the countries of Africa to the south of Sahara (29% of all cases of tuberculosis per head); half of new cases of tuberculosis fall on Asian countries: Bangladesh, China, India, Indonesia, Pakistan, Philippines. The governments of Big Eight maintain activities that have stabilized morbidity of tuberculosis on a world scale. Over 11 years (1995 - 2006) World Health Organization (WHO) implemented the DOTS strategy (Directly Observed Treatment with Short course of chemotherapy) in 183 countries and tested it on 26 millions patients with tuberculosis. Global data acquisition in 2005 found out morbidity of tuberculosis in 59% (the aim is 70%) and successful cure in 84% cases (the aim is 85 %). In 2006 WHO started realization of the Global Plan "Stop tuberculosis" (2006 - 2012). At the present time Global Fund use about 17% its resources to finance programs against tuberculosis. These funds help to reveal 5 millions extra cases of tuberculosis and cure 3 millions patients in the network of DOTS.

    Pre-exposure prophylaxis (PrEP) is recommended by the World Health Organization as an effective method of HIV prevention for individuals at risk for infection. In this paper, we describe the unique role that Thailand has played in the global effort to combat the HIV epidemic, including its role in proving the efficacy of PrEP, and discuss the opportunities and challenges of implementing PrEP in a middle-income country. Thailand was one of the first countries in the world to successfully reverse a generalized HIV epidemic. Despite this early success, HIV prevalence has remained high among people who inject drugs and has surged among men who have sex with men (MSM) and transgender women (TGW). Two pivotal trials that showed that the use of oral antiretroviral medication as PrEP can reduce HIV transmission were conducted partially or entirely at Thai sites. Demonstration projects of PrEP, as well as clinical trials of alternative PrEP regimens, began or will begin in 2014-2015 in Thailand and will provide additional data and experience on how to best implement PrEP for high-risk individuals in the community. Financing of drug costs, the need for routine laboratory monitoring and lack of awareness about PrEP among at-risk groups all present challenges to the wider implementation of PrEP for HIV prevention in Thailand. Although significant challenges to wider use remain, PrEP holds promise as a safe and highly effective method to be used as part of a combined HIV prevention strategy for MSM and TGW in Thailand.

    ;and an abstract database, Medical Intelligence Solution, for citations through April 2008. Specific search terms used were palivizumab with patient compliance, patient adherence, or patient persistence. Twenty-five articles and abstracts met the inclusion criteria. Available studies were mostly retrospective or observational prospective.Compliance, defined in various ways across the studies, varied between 25% and 100%, and 12 studies identified some of the factors related to noncompliance. Compliance generally was lower among Medicaid patients,African American patients, and other minorities. Ten studies (3 manuscripts and 7 abstracts) investigated the association of administration of prophylaxis through monthly home visits by a health professional with parental compliance with therapy. Most of the home-based programs were associated with higher compliance rates compared with clinic or office programs.Rates as high as 94% and 64% were achieved when Medicaid infants and infants of minority descent, respectively, received their doses through a home health program. When these infants received their doses at a clinic or office, depending on the definition of compliance, rates were 61%-100% for Medicaid infants and 44% for infants of minority descent. Reminder telephone calls to parents or caregivers, comprehensive multidisciplinary programs that included extensive counseling of parents, calendars with sticker reminders, and education in the language native to parents also were associated with increased compliance, although statistical significance was reported in only 1 study. Several studies recommended educating parents on the benefits of RSV prophylaxis, alleviating transportation and language difficulties, recognizing cultural differences and biases, and clarifying misperception of RSV illness severity. Home health programs had lower rates of RSV hospitalizations than office-based programs in 3 analyses conducted in 2 studies. In 4 other abstracts, the rates of RSV

  1. Effects of formalin-inactivated respiratory syncytial virus (FI-RSV in the perinatal lamb model of RSV.

    Directory of Open Access Journals (Sweden)

    Rachel J Derscheid

    Full Text Available Respiratory syncytial virus (RSV is the most frequent cause of bronchiolitis in infants and children worldwide. There are currently no licensed vaccines or effective antivirals. The lack of a vaccine is partly due to increased caution following the aftermath of a failed clinical trial of a formalin-inactivated RSV vaccine (FI-RSV conducted in the 1960's that led to enhanced disease, necessitating hospitalization of 80% of vaccine recipients and resulting in two fatalities. Perinatal lamb lungs are similar in size, structure and physiology to those of human infants and are susceptible to human strains of RSV that induce similar lesions as those observed in infected human infants. We sought to determine if perinatal lambs immunized with FI-RSV would develop key features of vaccine-enhanced disease. This was tested in colostrum-deprived lambs immunized at 3-5 days of age with FI-RSV followed two weeks later by RSV infection. The FI-RSV-vaccinated lambs exhibited several key features of RSV vaccine-enhanced disease, including reduced RSV titers in bronchoalveolar lavage fluid and lung, and increased infiltration of peribronchiolar and perivascular lymphocytes compared to lambs either undergoing an acute RSV infection or naïve controls; all features of RSV vaccine-enhanced disease. These results represent a first step proof-of-principle demonstration that the lamb can develop altered responses to RSV following FI-RSV vaccination. The lamb model may be useful for future mechanistic studies as well as the assessment of RSV vaccines designed for infants.

    Because it is not easy to differentiate Influenza virus (Flu) from RS virus (RSV) just by clinical symptoms, to accurately diagnose those viruses in conjunction with patient's clinical symptoms, rapid diagnostic kits has been used separately for each of those viruses. In our new study, we have developed a new rapid diagnostic kit, QuickNavi™-Flu+RSV. The kit can detect Flu A, Flu B, and RSV antigens with a single sample collection and an assay. Total of 2,873 cases (including nasopharyngeal swabs and nasopharyngeal aspirates specimens) in 2010/2011 and 2011/2012 seasons were evaluated with QuickNavi™-Flu+RSV and a commercially available kit. Sensitivity, specificity, and accuracy of Flu type A, type B, and RSV were above 95% when compared to commercially available kits (QuickNavi™-Flu and QuickNavi™-RSV) and considered to be equivalent to the commercially available kits. In 2011/2012 season, RSV infections increased prior to Flu season and continued during the peak of the Flu season. The kit can contribute to accurate diagnosis of Flu and RSV infections since co-infection cases have also been reported during the 2011/2012 season. QuickNavi™-Flu+RSV is useful for differential diagnosis of respiratory infectious diseases since it can detect Flu type A, type B, and RSV virus antigens with a single sample collection.

    Full Text Available RSV is the main cause of childhood lower respiratory infections, globally, an important cause of childhood wheeze and may be responsible for a substantial burden of disease in the very elderly and in adults with chronic medical problems, such as COPD. It is thus responsible for substantial healthcare and social costs. There are currently many companies and academic groups developing and testing candidate vaccines and there is an expectation that these will lead to effective and safe vaccines which will be available to health systems globally in the short- medium term. Despite this, there is an incomplete understanding of RSV disease, especially in adult groups, and large scale data are only available from a few countries and settings leading to low levels of awareness of the importance of this pathogen. We discuss the need for widespread national sentinel systems of RSV surveillance and some means by which this could be achieved. These data will be needed by national policy makers and immunisation advisory groups to guide future priority setting and decision making.

    Full Text Available Abstract Background Respiratory Syncytial Virus (RSV infection is usually restricted to the respiratory epithelium. Few studies have documented the presence of RSV in the systemic circulation, however there is no consistent information whether virus detection in the blood correlates with disease severity. Methods Balb/c mice were inoculated with live RSV, heat-inactivated RSV or medium. A subset of RSV-infected mice was treated with anti-RSV antibody 72 h post-inoculation. RSV RNA loads were measured by PCR in peripheral blood from day 1-21 post-inoculation and were correlated with upper and lower respiratory tract viral loads, the systemic cytokine response, lung inflammation and pulmonary function. Immunohistochemical staining was used to define the localization of RSV antigens in the respiratory tract and peripheral blood. Results RSV RNA loads were detected in peripheral blood from day 1 to 14 post-inoculation, peaked on day 5 and significantly correlated with nasal and lung RSV loads, airway obstruction, and blood CCL2 and CXCL1 expression. Treatment with anti-RSV antibody reduced blood RSV RNA loads and improved airway obstruction. Immunostaining identified RSV antigens in alveolar macrophages and peripheral blood monocytes. Conclusions RSV RNA was detected in peripheral blood upon infection with live RSV, followed a time-course parallel to viral loads assessed in the respiratory tract and was significantly correlated with RSV-induced airway disease.

    find any relevant studies that may have been missed. The risk factors identified from the systematic review of included studies were analysed and synthesised using stata. The base-case decision tree model developed in the original HTA journal publication [Health Technol Assess 2008;12(36)] was used to derive the cost-effectiveness of immunoprophylaxis of RSV using palivizumab in different subgroups of pre-term infants and young children who are at high risk of serious morbidity from RSV infection. Cost-effective spectra of prophylaxis with palivizumab compared with no prophylaxis for children without CLD/CHD, children with CLD, children with acyanotic CHD and children with cyanotic CHD were derived. Thirteen studies were included in this analysis. Analysis of 16,128 subgroups showed that prophylaxis with palivizumab may be cost-effective [at a willingness-to-pay threshold of £30,000/quality-adjusted life-year (QALY)] for some subgroups. For example, for children without CLD or CHD, the cost-effective subgroups included children under 6 weeks old at the start of the RSV season who had at least two other risk factors that were considered in this report and were born at 24 weeks gestational age (GA) or less, but did not include children who were > 9 months old at the start of the RSV season or had a GA of > 32 weeks. For children with CLD, the cost-effective subgroups included children 21 months old at the start of the RSV season. For children with acyanotic CHD, the cost-effective subgroups included children 21 months old at the start of the RSV season. For children with cyanotic CHD, the cost-effective subgroups included children 12 months old at the start of the RSV season. The poor quality of the studies feeding numerical results into this analysis means that the true cost-effectiveness may vary considerably from that estimated here. There is a risk that the relatively high mathematical precision of the point estimates of cost-effectiveness may be quite inaccurate

    Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract infections in infants and young children. RSV is characterised by high variability, especially in the G glycoprotein, which may play a significant role in RSV pathogenicity by allowing immune evasion. To reconstruct the origin and phylodynamic history of RSV, we evaluated the genetic diversity and evolutionary dynamics of RSV A and RSV B isolated from children under 3 years old infected in Italy from 2006 to 2012. Phylogenetic analysis revealed that most of the RSV A sequences clustered with the NA1 genotype, and RSV B sequences were included in the Buenos Aires genotype. The mean evolutionary rates for RSV A and RSV B were estimated to be 2.1 × 10(-3) substitutions (subs)/site/year and 3.03 × 10(-3) subs/site/year, respectively. The time of most recent common ancestor for the tree root went back to the 1940s (95% highest posterior density-HPD: 1927-1951) for RSV A and the 1950s (95%HPD: 1951-1960) for RSV B. The RSV A Bayesian skyline plot (BSP) showed a decrease in transmission events ending in about 2005, when a sharp growth restored the original viral population size. RSV B BSP showed a similar trend. Site-specific selection analysis identified 10 codons under positive selection in RSV A sequences and only one site in RSV B sequences. Although RSV remains difficult to control due to its antigenic diversity, it is important to monitor changes in its coding sequences, to permit the identification of future epidemic strains and to implement vaccine and therapy strategies.

    Mechanical measures such as graduated compression stockings and intermittent compression boots are available for venous thrombosis prophylaxis, but compliance may be limited. Plantar venous pneumatic compression devices have attained widespread acceptance by both patients and nurses because of their comfort and compact size, but their track record for efficacy is poor. Inferior vena cava filters prevent pulmonary embolism, but do not halt the thrombotic process or prevent venous thrombosis. Pharmacologic prophylaxis traditionally has relied upon minidose unfractionated heparin; however, re-examination is warranted in the face of increasingly ill and complex patients. My opinion is that small, fixed doses of once-daily low molecular weight heparin will eventually replace minidose unfractionated heparin as the standard pharmacologic prophylaxis regimen for most surgical and medical patients. Prolongation of prophylaxis after hospital discharge should receive increased emphasis. Most patients being transferred to a skilled nursing facility should receive venous thromboembolism prophylaxis. Similarly, most patients undergoing total hip or knee replacement should receive prolonged preventive regimens, with at least 1 month of anticoagulation. Despite advances, certain aspects of venous thrombosis prophylaxis remain problematic. First, a surprisingly high number of hospitalized patients develop venous thrombosis because of failed (rather than omitted) prophylaxis. Second, many patients in intensive care have a combination of peripheral vascular disease and active bleeding (usually gastrointestinal) that precludes mechanical or pharmacologic prophylaxis. Third, neurosurgical patients undergoing craniotomy for brain tumors suffer a high rate of venous thrombosis and major pulmonary embolism despite the routine use of combined mechanical and pharmacologic prophylaxis. My opinion is that these three areas, in addition to the hospital culture of prophylaxis, should receive

    Full Text Available Abstract Background Respiratory syncytial virus (RSV is a leading cause of lower respiratory tract infections (LRTIs in children globally. Predisposing conditions for the development of serious RSV disease include preterm infants and those with cardiopulmonary illness, including congenital heart disease (CHD and bronchopulmonary dysplasia (BPD. No vaccine is currently approved for the prevention of RSV infection. It is recommended that children at high risk be prophylactically administered palivizumab, a monoclonal antibody that has been shown in a number of clinical studies to reduce hospitalization rates due to serious RSV infection. The objective of the current study was to determine the safety and effectiveness of palivizumab in preventing serious RSV disease in high-risk children in the Russian Federation. Children at high risk of serious RSV disease (ie, born at ≤35 wk gestational age and ≤6 mo of age, and/or aged ≤24 mo with BPD or hemodynamically significant CHD were enrolled. Subjects were to receive 3 to 5 monthly injections of palivizumab 15 mg/kg (depending on the month of the initial injection over the RSV season. The primary endpoint was RSV-related hospitalizations. Adverse events (AEs were reported through 100 days following the final injection. Results One hundred subjects received ≥1 injection of palivizumab; 94 completed their dosing schedule. There were no RSV hospitalizations or deaths. Six of 7 subjects hospitalized for respiratory/cardiac conditions had an RSV test, which was negative in all cases. Three non-serious AEs (acute intermittent rhinitis and rhinitis, 1 subject; atopic dermatitis, 1 subject were considered possibly related to palivizumab. All other AEs were mild or moderate and considered not related/probably not related to palivizumab. Conclusion Palivizumab was generally well tolerated and effectively prevented serious RSV infection in a mixed population of high-risk children in the Russian

    Most respiratory syncytial virus (RSV) vaccine candidates include fusion (F) protein in different conformations. Antigenic site II found in the different F conformations is the target of palivizumab, the only US Food and Drug Administration approved monoclonal antibody (mAb). Serum palivizumab-like antibody (PLA) is a potential serologic correlate of immunity. Our objective was to determine if different conformations of F protein in a palivizumab competitive antibody (PCA) assay affect the PLA concentrations. Four PCA assays were standardized using mAbs. Each contained prefusion, postfusion, or intermediate F forms. PLA concentrations were measured in acute and convalescent sera from 22 RSV/A and 18 RSV/B-infected adult hematopoietic cell transplant (HCT) recipients. PLA concentrations were calculated using a 4-parameter logistic regression model and analyzed for statistical significance. PCA assays revealed significantly greater PLA concentrations in convalescent sera; comparable increases in PLA concentration in RSV/A and RSV/B-infected HCT recipients; and significantly reduced PLA concentrations in HCT recipients who shed RSV ≥14 days. A significant positive correlation was observed between PCA assays and RSV neutralizing antibody titers. F protein conformation does not appear to have a measurable impact on PCA assays for measuring PLA induced by RSV/A or RSV/B infection.

    This study aimed at estimating the efficiency of palivizumab in the prevention of Respiratory Syncytial Virus (RSV) infection and its sequelae in preterm infants (32 day 1 -35 day 0 weeks of gestational age -wGA-) in Spain. A decision-tree model was developed to compare health benefits (Quality Adjusted Life Years-QALYs) and costs of palivizumab versus a non-prophylaxis strategy over 6 years. A hypothetical cohort of 1,000 preterm infants, 32 day 1 -35 day 0 wGA (4.356 kg average weight) at the beginning of the prophylaxis (15 mg/kg of palivizumab; 3.88 average number of injections per RSV season) was analysed. The model considered the most recent evidence from Spanish observational and epidemiological studies on RSV infection: the FLIP II study provided hospital admission and Intensive Care Unit (ICU) admission rates; in-hospital mortality rate was drawn from an epidemiological study from 2004 to 2012; recurrent wheezing rates associated to RSV infection from SPRING study were adjusted by the evidence on the palivizumab effect from clinical trials. Quality of life baseline value, number of hospitalized infants and the presence of recurrent wheezing over time were granted to estimate QALYs. National Health Service and societal perspective (included also recurrent wheezing indirect cost) were analysed. Total costs (€, 2016) included pharmaceutical and administration costs, hospitalization costs and recurrent wheezing management annual costs. A discount rate of 3.0% was applied annually for both costs and health outcomes. Over 6 years, the base case analysis showed that palivizumab was associated to an increase of 0.0731 QALYs compared to non-prophylaxis. Total costs were estimated in €2,110.71 (palivizumab) and €671.68 (non-prophylaxis) from the National Health System (NHS) perspective, resulting in an incremental cost utility ratio (ICUR) of €19,697.69/QALYs gained (prophylaxis vs non-prophylaxis).

    Background: despite the proven effectiveness of preventive therapy for deep vein thrombosis, a significant proportion of patients at risk for thromboembolism do not receive prophylaxis during hospitalization. Our objective was to determine the adherence to thrombosis prophylaxis guidelines in a general hospital as a quality control strategy. Methods: a random audit of clinical charts was conducted at the Tijuana General Hospital, Baja California, Mexico, to determine the degree of adherence to deep vein thrombosis prophylaxis guidelines. The instrument used was the Caprini's checklist for thrombosis risk assessment in adult patients. Results: the sample included 300 patient charts; 182 (60.7 %) were surgical patients and 118 were medical patients. Forty six patients (15.3 %) received deep vein thrombosis pharmacologic prophylaxis; 27.1 % of medical patients received deep vein thrombosis prophylaxis versus 8.3 % of surgical patients (p < 0.0001). Conclusions: our results show that adherence to DVT prophylaxis at our hospital is extremely low. Only 15.3 % of our patients at risk received treatment, and even patients with very high risk received treatment in less than 25 % of the cases. We have implemented strategies to increase compliance with clinical guidelines.

    2017 will mark the 60 th anniversary since the first isolation of RSV in children. In spite of concerted efforts over all these years, the goal of developing an effective vaccine against paediatric RSV disease has remained elusive. One of the main hurdles standing in the way of an effective vaccine is the fact that the age incidence of severe disease peaks within the first 3 months of life, providing limited opportunity for intervention. In addition to this complexity, the spectre of failed historical vaccines, which increased the risk of illness and death upon subsequent natural infection, has substantially increased the safety criteria against which modern vaccines will be assessed. This review traces the history of RSV vaccine development for young infants and analyses the potential reasons for the failure of historic vaccines. It also discusses recent breakthroughs in vaccine antigen design and the progressive evolution of platforms for the delivery of these antigens to seronegative infants. © 2017 The British Infection Association.

    Resistance to Soybean mosaic virus (SMV) in soybean is conferred by three dominant genes: Rsv1, Rsv3 and Rsv4. Over the years, scientists in the USA have utilized a set of standard pathotypes, SMV-G1 to SMV-G7, to study interaction with Rsv-genotype soybeans. However, these pathotypes were isolated from a collection of imported soybean germplasm over 30 years ago. In this study, 35 SMV field isolates collected in recent years from 11 states were evaluated for gain of virulence on soybean genotypes containing individual Rsv genes. All isolates were avirulent on L78-379 (Rsv1), whereas 19 were virulent on L29 (Rsv3). On PI88788 (Rsv4), 14 of 15 isolates tested were virulent; however, only one was capable of systemically infecting all of the inoculated V94-5152 (Rsv4). Nevertheless, virulent variants from 11 other field isolates were rapidly selected on initial inoculation onto V94-5152 (Rsv4). The P3 cistrons of the original isolates and their variants on Rsv4-genotype soybeans were sequenced. Analysis showed that virulence on PI88788 (Rsv4) was not associated, in general, with selection of any new amino acid, whereas Q1033K and G1054R substitutions were consistently selected on V94-5152 (Rsv4). The role of Q1033K and G1054R substitutions, individually or in combination, in virulence on V94-5152 (Rsv4) was confirmed on reconstruction in the P3 cistron of avirulent SMV-N, followed by biolistic inoculation. Collectively, our data demonstrate that SMV has evolved virulence towards Rsv3 and Rsv4, but not Rsv1, in the USA. Furthermore, they confirm that SMV virulence determinants on V94-5152 (Rsv4) reside on P3. © 2012 THE AUTHORS. MOLECULAR PLANT PATHOLOGY © 2012 BSPP AND BLACKWELL PUBLISHING LTD.

    Full Text Available BACKGROUND: The clinical presentation of Bordetella pertussis can overlap with that of respiratory syncytial virus (RSV; however, management differs.HYPOTHESIS: First, the prevalence of B. pertussis is less than 2% among patients screened for RSV, and second the prevalence of B. parapertussis is also less than 2% among these patients.METHODS: Nasal washings submitted to a clinical laboratory for RSV screening were tested for B. pertussis and B. parapertussis, using species-specific real-time polymerase chain reaction (PCR assays. These were optimized to target conserved regions within a complement gene and the CarB gene, respectively. A Bordetella spp. genus-specific real-time PCR assay was designed to detect the Bhur gene of B. pertussis, B. parapertussis, and B. bronchiseptica. RSV A and B subtypes were tested by reverse transcription-PCR.RESULTS: Four hundred and eighty-nine clinical samples were tested. There was insufficient material to complete testing for one B. pertussis, 10 RSV subtype A, and four RSV subtype B assays. Bordetella pertussis was detected in 3/488 (0.6% (95% CI 0.1% to 1.8%, while B. parapertussis was detected in 5/489 (1.0% (95% CI 0.3% to 2.4%. Dual infection of B. pertussis with RSV and of B. parapertussis with RSV occurred in two and in three cases respectively. RSV was detected by PCR in 127 (26.5%.CONCLUSION: The prevalence of B. pertussis in nasal washings submitted for RSV screening was less than 2%. The prevalence of parapertussis may be higher than 2%. RSV with B. pertussis and RSV with B. parapertussis coinfection do occur.

    Previously, recombinant human respiratory syncytial virus (RSV) monoclonal antibody Fabs were generated by antigen selection from random combinatorial libraries displayed at the tip of filamentous phage. Two such Fabs, which exhibited high binding affinity for RSV F glycoprotein (a major protective antigen), were evaluated for therapeutic efficacy in infected mice just before or at the time of peak virus replication in the lungs. Fab 19, which neutralized RSV infectivity with high efficiency in tissue culture, was effective therapeutically when delivered directly into the lungs by intranasal instillation under anesthesia. In contrast, RSV Fab 126, which failed to neutralize virus in cell culture, did not exhibit a therapeutic effect under these conditions. The amount of Fab 19 required to effect a 5000- to 12,000-fold reduction in titer of RSV in the lungs within 24 hr was rather small. In four separate experiments, a single instillation of 12.9-50 μg of RSV Fab 19 was sufficient to achieve such a reduction in pulmonary virus in a 25g mouse. The use of Fabs instead of the whole immunoglobulin molecules from which they are derived reduced the protein content of a therapeutic dose. This is important because the protein load that can be delivered effectively into the lungs is limited. The therapeutic effect of a single treatment with Fab 19 was not sustained, so that a rebound in pulmonary virus titer occurred on the 2nd day after treatment. This rebound in pulmonary RSV titer could be prevented by treating infected mice with a single dose of Fab 19 daily for 3 days. These observations suggest that human monoclonal Fabs grown in Escherichia coli may prove useful in the treatment of serious RSV disease as well as diseases caused by other viruses where replication in vivo is limited primarily to the lumenal lining of the respiratory tract.

    further understand hMPV-associated illness, compare clinical characteristics of hMPV and RSV and establish the utility of routine screening for hMPV.hMPV-associated illnesses were retrospectively identified and described among children with respiratory symptoms admitted to a tertiary care center in southeast Michigan during the 2006-2007 respiratory viral season. A convenience sample of 256 nasopharyngeal specimens was subjected to nucleic acid extraction and amplification to identify those specimens positive for hMPV.  Medical record review was undertaken to retrieve demographic and clinical data of patients with hMPV, comparing them to RSV-positive patients and patients evaluated for respiratory symptoms who were negative for hMPV and RSV.hMPV was the second most commonly identified virus after RSV.  hMPV-positive patients were older than RSV-positive patients.  Among hMPV-positive patients, pneumonia was diagnosed in 37.5%, bronchiolitis was diagnosed in 31.2%, peribronchial cuffing was present on chest radiographs of 37.5%, antibiotic treatment was used in 81.2% and admission to the ICU was seen in 37.5%.  Finally, hMPV-positive patients were more likely to have fever than RSV-positive patients or patients negative for hMPV and RSV. hMPV is a major pathogen associated with hospitalization of children and is associated with the same severity of illness as RSV but in a slightly older population.   Due to apparent prevalence and severity of illness, routine screening should be implemented.

  8. Mucosal delivery of a vectored RSV vaccine is safe and elicits protective immunity in rodents and nonhuman primates

    Directory of Open Access Journals (Sweden)

    Angiolo Pierantoni

    Full Text Available Respiratory Syncytial Virus (RSV is a leading cause of severe respiratory disease in infants and the elderly. No vaccine is presently available to address this major unmet medical need. We generated a new genetic vaccine based on chimpanzee Adenovirus (PanAd3-RSV and Modified Vaccinia Ankara RSV (MVA-RSV encoding the F, N, and M2-1 proteins of RSV, for the induction of neutralizing antibodies and broad cellular immunity. Because RSV infection is restricted to the respiratory tract, we compared intranasal (IN and intramuscular (M administration for safety, immunogenicity, and efficacy in different species. A single IN or IM vaccination completely protected BALB/c mice and cotton rats against RSV replication in the lungs. However, only IN administration could prevent infection in the upper respiratory tract. IM vaccination with MVA-RSV also protected cotton rats from lower respiratory tract infection in the absence of detectable neutralizing antibodies. Heterologous prime boost with PanAd3-RSV and MVA-RSV elicited high neutralizing antibody titers and broad T-cell responses in nonhuman primates. In addition, animals primed in the nose developed mucosal IgA against the F protein. In conclusion, we have shown that our vectored RSV vaccine induces potent cellular and humoral responses in a primate model, providing strong support for clinical testing.

    We previously demonstrated that the severe cytokine storm and pathology associated with RSV infection following intramuscular vaccination of cotton rats with FI-RSV Lot 100 could be completely abolished by formulating the vaccine with the mild TLR4 agonist and adjuvant, monophosphoryl lipid A (MPL). Despite this significant improvement, the vaccine failed to blunt viral replication in the lungs. Since MPL is a weak TLR4 agonist, we hypothesized that its adjuvant activity was mediated by modulating the innate immune response of respiratory tract resident macrophages. Therefore, we developed a new vaccine preparation with purified, baculovirus expressed, partially purified, anchorless RSV F protein formulated with synthetic MPL that was administered to cotton rats intranasally, followed by an intradermal boost. This novel formulation and heterologous "prime/boost" route of administration resulted in decreased viral titers compared to that seen in animals vaccinated with F protein alone. Furthermore, animals vaccinated by this route showed no evidence of enhanced lung pathology upon RSV infection. This indicates that MPL acts as an immune modulator that protects the host from vaccine-enhanced pathology, and reduces RSV replication in the lower respiratory tract when administered by a heterologous prime/boost immunization regimen.

    RSV-infected children demonstrate various radiographic features, some of which are associated with worse clinical outcomes. To investigate whether specific chest radiological patterns in RSV-infected children with acute respiratory failure (ARF) in the peri-intubation period are associated with prolonged duration of mechanical ventilation. We included RSV-infected children 8 days, a backward stepwise regression arrived at a model that included age and right and left lung atelectasis. Using day 2 chest radiograph results, the best model included age and left lung atelectasis. A model combining the two days' findings yielded an area under the ROC curve of 0.92 with a satisfactory fit (P = 0.95). Chest radiological patterns around the time of intubation can identify children with RSV-associated ARF who would require prolonged mechanical ventilation. (orig.)

    Currently full dose prophylaxis is the standard of care in the treatment of hemophilia (World Federation of Hemophilia). However, the high costs prevent the use of standard or intermediate dose prophylaxis in China and other developing countries. Low dose prophylaxis would be a viable alternative treatment. At present global research data on the use of low dose prophylaxis is limited. Areas covered: Since 2007, China has been developing low dose prophylaxis as a high priority (90 % of moderate and severe hemophilia boys suffer joint disease by age 6 - 9). 11 studies were successfully conducted and published results showing evidence of the benefits of low dose prophylaxis to reduce joint bleeding. This new knowledge has been implemented into clinical practice in China. However the long-term outcome of arthropathy remains unclear and obstacles in execution exist. Expert commentary: In 2016, the first phenotype-based individualized prophylaxis study using four escalating low dose regimens on severe Chinese hemophilia A boys (China Individualized Prophylaxis Study (CHIP China)) launched. Using the previously published and imminent CHIP data, the goal for China is to establish an effective escalating low dose prophylaxis protocol for use in China as a standard of care.

    The airway expression of type III interferons (IFNs) was evaluated in infants hospitalized for respiratory syncytial virus (RSV) or rhinovirus (HRV) bronchiolitis. As an additional objective we sought to determine whether a different expression of IFN lambda 1-3 was associated with different harboring viruses, the clinical course of bronchiolitis or with the levels of well established IFN stimulated genes (ISGs), such as mixovirus resistance A (MxA) and ISG56. The analysis was undertaken in 118 infants with RSV or HRV bronchiolitis. Nasopharyngeal washes were collected for virological studies and molecular analysis of type III IFN responses. RSV elicited higher levels of IFN lambda subtypes when compared with HRV. A similar expression of type III IFN was found in RSVA or RSVB infected infants and in those infected with HRVA or HRVC viruses. Results also indicate that IFN lambda 1 and IFN lambda 2-3 levels were correlated with each other and with MxA and ISG56-mRNAs. In addition, a positive correlation exists between the IFN lambda1 levels and the clinical score index during RSV infection. In particular, higher IFN lambda 1 levels are associated to an increase of respiratory rate. These findings show that differences in the IFN lambda 1-3 levels in infants with RSV or HRV infections are present and that the expression of IFN lambda 1 correlates with the severity of RSV bronchiolitis.

    Full Text Available Respiratory syncytial virus (RSV circulates year round in Taiwan. A novel six consecutive monthly doses of palivizumab for RSV prevention protocol has been approved for high risk preterm infants since December 2010. This study aimed to determine the clinical effectiveness and safety of this novel protocol for the prevention of RSV infection.From April 2011 to March 2013, we enrolled infants born at ≤28 weeks gestation and infants born at ≤35 weeks gestation with chronic lung disease (CLD who received palivizumab prophylaxis as study group and followed up for 12 months. Historic control, those who were born and followed up between July 2000 and June 2008, were retrieved for propensity score matching. Primary endpoint was RSV-related hospitalization, and secondary endpoints included the length of hospital stay and intensive care unit (ICU care.We enrolled 127 infants (108 infants born at ≤28 weeks and 19 infants born at 29-35 weeks with CLD. They completed 6-dose palivizumab as scheduled. Among the study group, the RSV-related hospitalizations were 2 (1.6% within 6 months and 5 (3.9% within 12 months after discharge. We matched 127 infants in the control group with 127 infants in the study group by propensity score matching. The reduction of RSV-related hospitalization rates were 86% (10.2% vs 1.6%, p = 0.002 within 6 months after discharge and 78% (15.7% vs 3.9%, p = 0.004 within 12 months after discharge. Compared to the control group, the rate of ICU care significantly decreased from 7.1% to 0.8% (p = 0.024 within 6 months after discharge and from 7.9% to 0.8% (p = 0.014 within 12 months after discharge. Adverse events were recorded in 6.4% injections.Six monthly intramuscular administration of palivizumab is effective for prevention of RSV hospitalization in regions with no single seasonal peak of RSV infection such as Taiwan.

    Full Text Available Despite substantial morbidity associated with respiratory syncytial virus (RSV infection, there is no licensed vaccine. MEDI-559 is a live attenuated intranasal vaccine candidate being developed for prevention of lower respiratory illness due to RSV in young children. This randomized, placebo-controlled study evaluated safety of MEDI-559 in healthy, RSV-seronegative children. MEDI-559 or placebo was administered on 3 occasions, 2 months apart. Primary safety was based on solicited symptoms (SSs and adverse events (AEs collected for 28 days after each dose. Nasal wash samples were collected 3 times after each dose (days 7-10, 12-18, 28-34 and at sick visits. Serum was collected for measuring antibody immune responses to RSV prior to first vaccination and 28 days post final dose. Long-term safety was monitored for 365 days from first dose. SSs were mild and frequent (MEDI-559 84%; placebo 91%; most common SSs were runny/stuffy nose, cough, and irritability/fussiness. AEs occurred in 67% MEDI-559 and 57% placebo recipients: most common AE was upper respiratory tract infection (MEDI-559 35%; placebo 23%. Higher incidence of medically attended lower respiratory illness within 28 days after dosing occurred in the MEDI-559 arm compared to placebo (none associated with vaccine virus shedding. There was no evidence of enhanced RSV disease. Vaccine virus was detected only in MEDI-559 recipients; shedding occurred in 56%subjects, primarily post dose 1. A functional immune response was observed in 59% and 9% MEDI-559 and placebo recipients, respectively, by an RSV microneutralization assay. Vaccine take, assessed by proportion that shed vaccine-type virus or had a seroresponse against RSV, was seen in 95% MEDI-559 subjects. MEDI-559 is therefore biologically active and immunogenic in this seronegative pediatric population. Although the frequency of SSs and AEs was not considered clinically significant, the increase in medically attended lower respiratory

    Full Text Available Abstract Background Respiratory syncytial virus (RSV infection is the major cause of bronchiolitis in infants and is a risk factor for the development of asthma. Allergic asthmatics are more susceptible to RSV infection and viral exacerbation. Methods Since the effectiveness of corticosteroids in treating RSV infection has been controversial, we tested fluticasone propionate (FP and salmeterol (Sal alone versus FP plus Sal (FPS on RSV-induced airway inflammation. Mice were sensitized and challenged with ovalbumin (OVA and infected with RSV. Following infection they were treated with FP, Sal, or FPS intranasally and airway hyperreactivity (AHR, inflammation and RSV titers were examined. Results The group treated with FPS showed significantly lower AHR compared to the group treated with FP or Sal alone. The group treated with FP alone showed slightly decreased (non-significant AHR compared to controls. Treatment with FPS resulted in significant decreases in the percentage of eosinophils and neutrophils in bronchoalveolar lavage fluid and in lung pathology compared to FP or Sal. FP alone decreased eosinophils but not neutrophils or lymphocytes, while Sal alone decreased eosinophils and neutrophils but not lymphocytes. FPS treatment of mice infected with RSV in the absence of allergen sensitization resulted in a 50% decrease of RSV titer in the lung and a reduction in neutrophils compared to FP or Sal. Conclusion Together, these results indicate that fluticasone in combination with salmeterol is a more effective treatment for decreasing airway hyperreactivity and inflammation than either of them alone in allergen-sensitized, RSV-infected mice.

  1. Acupuncture for migraine prophylaxis

    Full Text Available ABSTRACT BACKGROUND: Acupuncture is often used for migraine prophylaxis but its effectiveness is still controversial. This review (along with a companion review on 'Acupuncture for tension-type headache' represents an updated version of a Cochrane review originally published in Issue 1, 2001, of The Cochrane Library. OBJECTIVES: To investigate whether acupuncture is a more effective than no prophylactic treatment/routine care only; b more effective than 'sham' (placebo acupuncture; and c as effective as other interventions in reducing headache frequency in patients with migraine. METHODS: Search methods: The Cochrane Pain, Palliative & Supportive Care Trials Register, CENTRAL, MEDLINE, EMBASE and the Cochrane Complementary Medicine Field Trials Register were searched to January 2008. Selection criteria: We included randomized trials with a post-randomization observation period of at least 8 weeks that compared the clinical effects of an acupuncture intervention with a control (no prophylactic treatment or routine care only, a sham acupuncture intervention or another intervention in patients with migraine. Data collection and analysis: Two reviewers checked eligibility; extracted information on patients, interventions, methods and results; and assessed risk of bias and quality of the acupuncture intervention. Outcomes extracted included response (outcome of primary interest, migraine attacks, migraine days, headache days and analgesic use. Pooled effect size estimates were calculated using a random-effects model. MAIN RESULTS: Twenty-two trials with 4419 participants (mean 201, median 42, range 27 to 1715 met the inclusion criteria. Six trials (including two large trials with 401 and 1715 patients compared acupuncture to no prophylactic treatment or routine care only. After 3 to 4 months patients receiving acupuncture had higher response rates and fewer headaches. The only study with long-term follow up saw no evidence that effects dissipated up

    Human respiratory syncytial virus (hRSV) is the most common cause of bronchiolitis and pneumonia in infants. The lack of proper prophylactics and therapeutics for controlling hRSV infection has been of great concern worldwide. Xylitol is a well-known sugar substitute and its effect against bacteria in the oral cavity is well known. However, little is known of its effect on viral infections. In this study, the effect of dietary xylitol on hRSV infection was investigated in a mouse model for the first time. Mice received xylitol for 14 d prior to virus challenge and for a further 3 d post challenge. Significantly larger reductions in lung virus titers were observed in the mice receiving xylitol than in the controls receiving phosphate-buffered saline (PBS). In addition, fewer CD3(+) and CD3(+)CD8(+) lymphocytes, whose numbers reflect inflammatory status, were recruited in the mice receiving xylitol. These results indicate that dietary xylitol can ameliorate hRSV infections and reduce inflammation-associated immune responses to hRSV infection.

    Abstract Background Incidence of respiratory syncytial virus (RSV) and rhinovirus (RHV) varies throughout the year. We aim to quantify the relationship between weather variables (temperature, humidity, precipitation, and aerosol concentration) and disease incidence in order to quantify how outbreaks of RSV and RHV are related to seasonal or sub-seasonal meteorology, and if these relationships can predict viral outbreaks of RSV and RHV. Methods Health data were collected in a community-based, prospective randomized trial of maternal influenza immunization of pregnant women and their infants conducted in rural Nepal from 2011–2014. Adult illness episodes were defined as fever plus cough, sore throat, runny nose, and/or myalgia, with infant illness defined similarly but without fever requirement. Cases were identified through longitudinal household-based weekly surveillance. Temperature, humidity, precipitation, and fine particulate matter (PM 2.5) data come from reanalysis data products NCEP, Era-Interim, and Merra-2, which are produced by assimilating historical in-situ and satellite-based observations into a weather model. Results RSV exhibits a relationship with temperature after removing the seasonal cycle (r = -0.16, N = 208, P = 0.02), and RHV exhibits a strong relationship to daily temperature (r =-0.14, N =208, P = 0.05). When lagging meteorology by up to 15 weeks, correlations with disease count and weather improve (RSV: r_max = 0.45, P < 0.05; RHV: r_max = 0.15, P = 0.05). We use an SIR model forced by lagged meteorological variables to predict RSV and RHV, suggesting that disease burden can be predicted at lead times of weeks to months. Conclusion Meteorological variables are associated with RSV and RHV incidence in rural Nepal and can be used to drive predictive models with a lead time of several months. Disclosures J.

  11. Optimization of prophylaxis for hemophilia A.

    Directory of Open Access Journals (Sweden)

    Robert D Herbert

    Full Text Available Prophylactic injections of factor VIII reduce the incidence of bleeds and slow the development of joint damage in people with hemophilia. The aim of this study was to identify optimal person-specific prophylaxis regimens for children with hemophilia A.Analytic and numerical methods were used to identify prophylaxis regimens which maximize the time for which plasma factor VIII concentrations exceed a threshold, maximize the lowest plasma factor VIII concentrations, and minimize risk of bleeds.It was demonstrated analytically that, for any injection schedule, the regimen that maximizes the lowest factor VIII concentration involves sharing doses between injections so that all of the trough concentrations in a prophylaxis cycle are equal. Numerical methods were used to identify optimal prophylaxis schedules and explore the trade-offs between efficacy and acceptability of different prophylaxis regimens. The prophylaxis regimen which minimizes risk of bleeds depends on the person's pattern of physical activity and may differ greatly from prophylaxis regimens that optimize pharmacokinetic parameters. Prophylaxis regimens which minimize risk of bleeds also differ from prophylaxis regimens that are typically prescribed. Predictions about which regimen is optimal are sensitive to estimates of the effects on risk of bleeds of factor VIII concentration and physical activity.The methods described here can be used to identify optimal, person-specific prophylaxis regimens for children with hemophilia A.

    Characterization and follow-up evaluation of chest CT of RSV pneumonia in immune-compromised adults during a seasonal epidemic. Retrospective analysis of 132 chest CT examinations of 51 adult immune-compromised patients (29 m/22f, diameter 58 years) with clinical signs of pneumonia and positive RSV test in winter 2011/2012. Two experienced chest radiologists evaluated the morphology (bronchial wall thickening, tree-in-bud, nodules, halo, ground-glass opacities, consolidations, pleural fluid) of the CT scans by consensus. Pathological findings were in 86 % of the chest CT scans: Areas of ground-glass attenuation in 64 %, consolidations in 56 %, nodules in 55 % (diameter 8 mm in maximal diameter, with halo in 71 %), pleural fluid in 44 % (diameter 2 cm), tree-in-bud in 36 %, bronchial wall thickening in 27 % and more than one morphological finding in 72 %. There were no pathological CT findings in 14 % of patients with clinical symptoms of pneumonia because these patients did not undergo follow-up. Radiological progression was found in 45 % of patients and regression in 33 % in follow-up examinations. In 37 % an additional examination of the paranasal sinuses was performed and showed sinusitis in 63 % of cases. 90 % of the patients had sinusitis as well as pneumonia. In addition to RSV, a further pathogenic agent was found in bronchoalveolar lavage of five patients (Aspergillus spec., herpes simplex virus, Pseudomonas aeruginosa). The most characteristic signs in chest CT scans were at the beginning of pneumonia with nodules and tree-in-bud often combined with bronchial wall thickening. The following CT scans showed characteristic but not pathognomonic chest CT findings of RSV pneumonia. These morphological findings should be recognized seasonally (winter) especially at the beginning of the case of pneumonia. RSV-associated additional sinusitis is probably common and should be noticed.

    The demand for rapid, accurate viral testing has increased the number of assays available for the detection of viral pathogens. One of the newest FDA cleared platforms is the Luminex ARIES ® Flu A/B & RSV, which is a fully automated, real-time PCR-based assay used for detection of influenza A, influenza B, and respiratory syncytial virus (RSV). We sought to compare the performance of Luminex ARIES ® Flu A/B & RSV assay to the Cepheid Xpert ® Flu/RSV XC assay for rapid Flu and RSV testing. A series of consecutive nasopharyngeal specimens received in the clinical microbiology laboratory during peak influenza season at a major academic center in Chicago, IL, were prospectively tested, using both the ARIES ® Flu A/B & RSV and Xpert ® Flu/RSV XC assays, side by side. Discrepant results were tested on the BioFire FilmArray ® Respiratory Panel for resolution. A total of 143 consecutive nasopharyngeal specimens, obtained from patients ranging from six months to ninety-three years in age were received between January 1st, 2017 and March 21st, 2017. There was 96.6% agreement between the two assays for detection influenza A, 100% agreement for detection influenza B and RSV, and 98.9% agreement for negative results. The Xpert ® Flu/RSV XC performed with an average turn-around time of approximately 60min, compared to the ARIES ® Flu A/B & RSV of approximately 120min. Both assays were equally easy to perform, with a similar amount of hands-on technologist time for each platform. Overall, these results indicate that both tests are comparable in terms of result agreement and technical ease-of-use. The Xpert ® Flu/RSV XC assay did produce results with less turn-around-time, approximately 60min quicker than the ARIES ® Flu A/B & RSV. Copyright © 2017 Elsevier B.V. All rights reserved.

    2010-10-01

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

    Full Text Available Abstract Background The aim of this study, conducted in Europe, was to develop a validated risk factor based model to predict RSV-related hospitalisation in premature infants born 33–35 weeks' gestational age (GA. Methods The predictive model was developed using risk factors captured in the Spanish FLIP dataset, a case-control study of 183 premature infants born between 33–35 weeks' GA who were hospitalised with RSV, and 371 age-matched controls. The model was validated internally by 100-fold bootstrapping. Discriminant function analysis was used to analyse combinations of risk factors to predict RSV hospitalisation. Successive models were chosen that had the highest probability for discriminating between hospitalised and non-hospitalised infants. Receiver operating characteristic (ROC curves were plotted. Results An initial 15 variable model was produced with a discriminant function of 72% and an area under the ROC curve of 0.795. A step-wise reduction exercise, alongside recalculations of some variables, produced a final model consisting of 7 variables: birth ± 10 weeks of start of season, birth weight, breast feeding for ≤ 2 months, siblings ≥ 2 years, family members with atopy, family members with wheeze, and gender. The discrimination of this model was 71% and the area under the ROC curve was 0.791. At the 0.75 sensitivity intercept, the false positive fraction was 0.33. The 100-fold bootstrapping resulted in a mean discriminant function of 72% (standard deviation: 2.18 and a median area under the ROC curve of 0.785 (range: 0.768–0.790, indicating a good internal validation. The calculated NNT for intervention to treat all at risk patients with a 75% level of protection was 11.7 (95% confidence interval: 9.5–13.6. Conclusion A robust model based on seven risk factors was developed, which is able to predict which premature infants born between 33–35 weeks' GA are at highest risk of hospitalisation from RSV. The model could be

    In this study, the interaction between the respiratory syncytial virus (RSV) fusion (F) protein, attachment (G) protein, and small hydrophobic (SH) proteins was examined. Immunoprecipitation analysis suggested that the F and G proteins exist as a protein complex on the surface of RSV-infected cells, and this conclusion was supported by ultracentrifugation analysis that demonstrated co-migration of surface-expressed F and G proteins. Although our analysis provided evidence for an interaction between the G and SH proteins, no evidence was obtained for a single protein complex involving all three of the virus proteins. These data suggest the existence of multiple virus glycoprotein complexes within the RSV envelope. Although the stimulus that drives RSV-mediated membrane fusion is unknown, the association between the G and F proteins suggest an indirect role for the G protein in this process

    The epithelial cells of the airways are the target cells for respiratory syncytial virus (RSV) infection and the site of the majority of the inflammation associated with the disease. Recently, peroxisome-proliferator-activated receptor γ (PPARγ), a member of the nuclear hormone receptor superfamily, has been shown to possess anti-inflammatory properties. Therefore, we investigated the role of PPARγ agonists (15d-PGJ 2 , ciglitazone and troglitazone) on the synthesis of RSV-induced cytokine release from RSV-infected human lung epithelial cells (A549). We observed that all PPARγ ligands inhibited dose-dependently the release of TNF-α, GM-CSF, IL-1α, IL-6 and the chemokines CXCL8 (IL-8) and CCL5 (RANTES) from RSV-infected A549 cells. Concomitantly, the PPARγ ligands diminished the cellular amount of mRNA encoding for IL-6, CXCL8 and CCL5 and the RSV-induced binding activity of the transcription factors NF-κB (p65/p50) and AP-1 (c-fos), respectively. Our data presented herein suggest a potential application of PPARγ ligands in the anti-inflammatory treatment of RSV infection

    The effect of RSV infection on the adherence of Streptococcus pneumoniae (SP), Haemophilus influenzae (HI) and Staphylococcus aureus (SA) to human epithelial cells was determined. RSV-infected Hep-2 cell cultures at different stages of expression of surface viral antigens and bacteria labeled with /sup 3/H-thymidine were employed to examine the kinetics of bacterial adherence to virus-infected cells. RSV infection did not alter the magnitude of adherence of HI or SA to HEp-2 cells. However, adherence of SP to HEp-2 cells was significantly (P < 0.01) enhanced by prior RSV infection. The degree of adherence was directly related to the amount of viral antigen expressed on the cell surface. The adherence was temperature dependent, with maximal adherence observed at 37/sup 0/C. Heat-inactivation of SP did not alter adherence characteristics. These data suggest that RSV infection increases adherence of SP to the surface of epithelial cells in vitro. Since attachment of bacteria to mucosal surfaces is the first step in many infections, it is suggested that viral infections of epithelial cells render them more susceptible to bacterial adherence. Thus, RSV infection in vivo may predispose children to SP infections, such as in otitis media, by increasing colonization with SP.

  1. Alveolar macrophage–derived type I interferons orchestrate innate immunity to RSV through recruitment of antiviral monocytes

    Type I interferons (IFNs) are important for host defense from viral infections, acting to restrict viral production in infected cells and to promote antiviral immune responses. However, the type I IFN system has also been associated with severe lung inflammatory disease in response to respiratory syncytial virus (RSV). Which cells produce type I IFNs upon RSV infection and how this directs immune responses to the virus, and potentially results in pathological inflammation, is unclear. Here, we show that alveolar macrophages (AMs) are the major source of type I IFNs upon RSV infection in mice. AMs detect RSV via mitochondrial antiviral signaling protein (MAVS)–coupled retinoic acid–inducible gene 1 (RIG-I)–like receptors (RLRs), and loss of MAVS greatly compromises innate immune restriction of RSV. This is largely attributable to loss of type I IFN–dependent induction of monocyte chemoattractants and subsequent reduced recruitment of inflammatory monocytes (infMo) to the lungs. Notably, the latter have potent antiviral activity and are essential to control infection and lessen disease severity. Thus, infMo recruitment constitutes an important and hitherto underappreciated, cell-extrinsic mechanism of type I IFN–mediated antiviral activity. Dysregulation of this system of host antiviral defense may underlie the development of RSV-induced severe lung inflammation. PMID:25897172

    Rice stripe disease, caused by Rice stripe virus (RSV), may lead to severe or even crippling losses in many rice-cultured countries and regions. As the most important vector of RSV, the small brown planthopper (SBPH) (Laodelphax striatellus) is largely responsible for the epidemic phase of the disease. Therefore, a rapid identification of RSV in the SBPH is of a great need for disease forecasting. A reverse transcription polymerase chain reaction (RT-PCR) assay is described to amplify a RSV gene in individual L. striatellus. By using primers matched to the viral RNA dependent RNA polymerase gene in RNA1, a 445 bp product was detected in viruliferous SBPHs. Meanwhile, the PCR products produced by the SBPH actin primers constructed across the boundary of an intron and an exon were used as RNA specific positive control for each stage of the experiment to ensure the validity of the negative results. Duplex RT-PCR conditions were established for the simultaneous detection of RSV and actin. This approach can be used for the early detection of RSV in L. striatellus and the subsequent rice stripe disease forecasting.

To evaluate the effects of albuterol use in young infants admitted with respiratory syncytial virus (RSV bronchiolitis with regards to length of time on supplemental oxygen and length of stay (LOS. To consider the possibility that albuterol use may increase the need for supplemental oxygen and increase LOS. Design, Setting, and Participants. Full-term infants between the ages of 11 days and 90 days (=316 were included in this retrospective study. Infants included were hospitalized with a diagnosis of RSV bronchiolitis at a university-affiliated children’s hospital. Results. In 4 of 5 severity groups, patients who received albuterol required more time on supplemental oxygen and had longer LOS. The differences only reached statistical significance in one of the severity groups in regards to LOS. Conclusions. The use of albuterol does not appear to be useful in the treatment of young infants with RSV bronchiolitis and may actually be harmful, in regards to increased supplemental oxygen need.

    Small animal models have been used to obtain many insights regarding the pathogenesis and immune responses induced following infection with human respiratory syncytial virus (hRSV). Amongst those described to date, infections in cotton rats, mice, guinea pigs, chinchillas and Syrian hamsters with hRSV strains Long and/or A2 have been well characterised, although clinical isolates have also been examined. Ferrets are also susceptible to hRSV infection but the pathogenesis and immune responses elicited following infection have not been well characterised. Herein, we describe the infection of adult ferrets with hRSV Long or A2 via the intranasal route and characterised virus replication, as well as cytokine induction, in the upper and lower airways. Virus replication and cytokine induction during the acute phase of infection (days 0-15 post-infection) were similar between the two strains and both elicited high levels of F glycoprotein-specific binding and neutralising antibodies following virus clearance (days 16-22 post-infection). Importantly, we demonstrate transmission from experimentally infected donor ferrets to co-housed naïve recipients and have characterised virus replication and cytokine induction in the upper airways of infected contact animals. Together, these studies provide a direct comparison of the pathogenesis of hRSV Long and A2 in ferrets and highlight the potential of this animal model to study serological responses and examine interventions that limit transmission of hRSV. IMPORTANCE Ferrets have been widely used to study pathogenesis, immunity and transmission following human influenza virus infections, however far less is known regarding the utility of the ferret model to study hRSV infections. Following intranasal (IN) infection of adult ferrets with the well characterised Long or A2 strains of hRSV, we report virus replication and cytokine induction in the upper and lower airways, as well as the development of virus-specific humoral responses

    Full Text Available Abstract Background Estimates of influenza and respiratory syncytial virus (RSV burden must be periodically updated to inform public health strategies. We estimated seasonal influenza- and RSV-attributable hospitalizations in the US from 1997 to 2009 according to age and risk status (NCT01599390. Methods Multiple linear regression modelling was used to attribute hospitalizations to influenza or RSV using virological surveillance and hospitalization data. Hospitalization data were obtained from the US Nationwide Inpatient Sample and virology data were obtained from FluView (Centers for Disease Control and Prevention. Outcomes included any mention of ICD-coded respiratory disease and cardiorespiratory disease diagnoses. We also explored a broader definition of respiratory disease that included mention of relevant respiratory sign/symptoms and viral infection (“respiratory broad”. Results Applying the respiratory broad outcome, our model attributed ~300,000 and ~200,000 hospitalizations to influenza and RSV, respectively. Influenza A/H3N2 was the predominant cause of influenza-related hospitalizations in most seasons, except in three seasons when influenza B was dominant; likewise, A/H3N2 caused most influenza-related hospitalizations in all age segments, except in children <18 years where the relative contribution of A/H3N2 and B was similar. Most influenza A- and B-related hospitalizations occurred in seniors while approximately one half and one third of all RSV-related events occurred in children 0–4 years and seniors 65+ years, respectively. High-risk status was associated with higher risk of both influenza- and RSV-attributable hospitalizations in adults, but not in children. Conclusions Our study assessed the burden of influenza and RSV, information that is important for both cost effectiveness studies and for prioritization of the development of antivirals and vaccines. For seniors, we found that the burdens of influenza and RSV were

    Emicizumab (ACE910) bridges activated factor IX and factor X to restore the function of activated factor VIII, which is deficient in persons with hemophilia A. This phase 3, multicenter trial assessed once-weekly subcutaneous emicizumab prophylaxis in persons with hemophilia A with factor VIII inhibitors. We enrolled participants who were 12 years of age or older. Those who had previously received episodic treatment with bypassing agents were randomly assigned in a 2:1 ratio to emicizumab prophylaxis (group A) or no prophylaxis (group B). The primary end point was the difference in bleeding rates between group A and group B. Participants who had previously received prophylactic treatment with bypassing agents received emicizumab prophylaxis in group C. A total of 109 male participants with hemophilia A with inhibitors were enrolled. The annualized bleeding rate was 2.9 events (95% confidence interval [CI], 1.7 to 5.0) among participants who were randomly assigned to emicizumab prophylaxis (group A, 35 participants) versus 23.3 events (95% CI, 12.3 to 43.9) among those assigned to no prophylaxis (group B, 18 participants), representing a significant difference of 87% in favor of emicizumab prophylaxis (Phemophilia A with inhibitors.

  8. Iodine Prophylaxis and Nuclear Accidents

    Iodine is a highly volatile element therefore being very mobile in the environment. It enters the metabolism of living organisms and is selectively taken up and concentrated in the thyroid gland. The plume (cloud-like formation) of radioactive material that might be released in the environment in the case of a serious nuclear accident, primarily consists of the radioactive isotopes of iodine. Among those, due to its decay properties, is the most important 131 I. The effective means of protecting the thyroid gland against exposure to radioactive iodine is an intake of stable iodine. Therefore, one of the central issues in the emergency planning is to determine whether and at which projected thyroid radiation dose stable iodine should be given to the population. The International Atomic Energy Agency (IAEA) set the generic optimized intervention value for iodine prophylaxis to 100 mGy of avertable committed dose to a thyroid.The prophylaxis is implemented by utilizing the pills of pills of potassium iodine (KI). The efficacy of KI in protecting the thyroid gland depends upon the time of intake relative to the start of exposure to radioactive iodine. The best results are obtained if KI is taken 1-2 hours before or immediately after the start of exposure. The recommended dosage, based upon the study performed by Il'in et.al. is 130 mg/day. KI should be taken at least three days after the acute exposure to radioiodine, to prevent accumulation in a thyroid gland of radioiodine excreted from the other compartments of the body. The largest epidemiological study on the effects of KI prophylaxis ever performed was the one in Poland after the Chernobyl accident. Stable iodine was given as single dose of KI solution to 10.5 million of children and 7 millions of adults. Among children no serious side effects were seen while only two adults (with previously recorded iodine sensitivity) had severe respiratory distresses. Polish experiences showed that rapid response to such

    Respiratory Syncytial Virus (RSV) infects respiratory epithelial cells and deregulates host gene expression by many mechanisms including expression of RSV G protein (RSV G). RSV G protein encodes a central conserved region (CCR) containing a CX3C motif that functions as a fractalkine mimic. Disruption of the CX3C motif (a.a. 182-186) located in the CCR of the G protein has been shown to affect G protein function in vitro and the severity of RSV disease pathogenesis in vivo. We show that infection of polarized Calu3 respiratory cells with recombinant RSV having point mutations in Cys173 and 176 (C173/176S) (rA2-GC12), or Cys186 (C186S) (rA2-GC4) is associated with a decline in the integrity of polarized Calu-3 cultures and decreased virus production. This is accompanied with downregulation of miRNAs let-7f and miR-24 and upregulation of interferon lambda (IFNλ), a primary antiviral cytokine for RSV in rA2-GC12/rA2-GC4 infected cells. These results suggest that residues in the cysteine noose region of RSV G protein can modulate IFN λ expression accompanied by downregulation of miRNAs, and are important for RSV G protein function and targeting.

    To review the evidence and provide recommendations on antibiotic prophylaxis for obstetrical procedures. Outcomes evaluated include need and effectiveness of antibiotics to prevent infections in obstetrical procedures. Published literature was retrieved through searches of Medline and The Cochrane Library on the topic of antibiotic prophylaxis in obstetrical procedures. Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. Searches were updated on a regular basis and articles published from January 1978 to June 2009 were incorporated in the guideline. Current guidelines published by the American College of Obstetrics and Gynecology were also incorporated. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The evidence obtained was reviewed and evaluated by the Infectious Diseases Committee of the Society of Obstetricians and Gynaecologists of Canada under the leadership of the principal authors, and recommendations were made according to guidelines developed by the Canadian Task Force on Preventive Health Care (Table 1). Implementation of this guideline should reduce the cost and harm resulting from the administration of antibiotics when they are not required and the harm resulting from failure to administer antibiotics when they would be beneficial. SUMMARY STATEMENTS: 1. Available evidence does not support the use of prophylactic antibiotics to reduce infectious morbidity following operative vaginal delivery. (II-1) 2. There is insufficient evidence to argue for or against the use of prophylactic antibiotics to reduce infectious morbidity for manual removal of the placenta. (III) 3.

    Given the lifelong therapy in haemophilia patients, insight in non-adherence behaviour from a patient perspective is important to understand patients' difficulties with the following treatment recommendations. The aim of this study was to clarify the process underlying adherence (behaviour) to prophylactic treatment, from a patients' perspective. To develop a grounded theory, a qualitative study using individual in-depth interviews was performed to understand experiences, perceptions and beliefs concerning adherence to prophylaxis. From two Dutch treatment centres, 21 adults with haemophilia using prophylaxis were interviewed. Patients were asked how they experience their task to administer prophylaxis and how they adhere to this. The interviews were transcribed, coded and analysed in an iterative process, leading to the development of the grounded theory. Adherence was determined by the position of prophylaxis in life. The position of prophylaxis was determined by the perception of prophylaxis and the ability to exert prophylaxis. Patients' perception was influenced by two main factors: acceptance of haemophilia and feeling/fearing symptoms. The ability to exert prophylaxis was influenced by understanding haemophilia and prophylaxis and planning/infusion skills. The combination of different perceptions and skills led to four main positions of prophylaxis in life: (i) prophylaxis integrated in life, (ii) prophylaxis according to doctors' advice, struggling with irregular situations, (iii) prophylaxis is too much to handle, (iv) prophylaxis is a confrontation with illness. The adherence level gradually decreased from position 1 to 4. This information can be used to design tailored interventions to promote adherence. © 2015 John Wiley & Sons Ltd.

Timely initiation of post exposure prophylaxis following an animal exposure can result in 100% preventability of this fatal disease.This facility based study was conducted among clinical fraternities of teaching hospitals. A semi structured questionnaire was used for collection of data. Institutional Ethics Committee approval was sought. The study investigators visited the workplace of the participants and distributed the questionnaire. SPSS Ver 16 (Chicago, IL, USA was used to analyse the data.Most of the participants knew that veterinary groups and zoo-keepers should be given pre-exposure prophylaxis. Many participants knew about the Intra Muscular schedule of anti-rabies vaccine and its site of administration for pre exposure prophylaxis. It was observed that most participants had knowledge regarding correct intramuscular regimen of anti-rabies vaccine for post-exposure prophylaxis but less than half were able to differentiate between the intramuscular and intradermal regimens. Less than half of participants were aware of the fact that local administration of anti-rabies serum is useful.The knowledge regarding WHO categorisation of animal exposure and recommended post exposure prophylaxis according to type of exposure observed to be minimal among clinical fraternity.

    RSV continues to be a high priority for vaccine and antiviral drug development. Unfortunately, no safe and effective RSV vaccine is available and treatment options are limited. Over the past decade, several studies have focused on the role of RSV G protein on viral entry, viral neutralization, and RSV-mediated pathology. Anti-G murine monoclonal antibody (mAb) 131-2G treatment has been previously shown to reduce weight loss, bronchoalveolar lavage (BAL) cell number, airway reactivity, and Th2-type cytokine production in RSV-infected mice more rapidly than a commercial humanized monoclonal antibody (mAb) against RSV F protein (Palivizumab). In this study, we have tested two human anti-RSV G mAbs, 2B11 and 3D3, by both prophylactic and therapeutic treatment for RSV in the BALB/c mouse model. Both anti-G mAbs reduced viral load, leukocyte infiltration and IFN-γ and IL-4 expression in cell-free BAL supernatants emphasizing the potential of anti-G mAbs as anti-inflammatory and antiviral strategies.

    Rhinovirus and respiratory syncytial virus (RSV) are the most prevalent inducers of upper respiratory tract infections (URTI) in infants and may stimulate immune maturation. To estimate the amount of immune stimulation, nasal immune responses were examined during rhinovirus and RSV-induced URTI in

    Each year 1.5 million children under the age of 5 years die from pneumonia. In the United States, respiratory syncytial virus (RSV) is the number one cause of bronchiolitis and pneumonia in children under 1 year of age. Low serum 25(OH)D is associated with an increased risk of lower respiratory tract infections (LRTI). Two recent studies have provided important information concerning the association between cord blood 25(OH)D and subsequent risk of developing respiratory infection in very young children. These findings support the need in future studies to determine the extent to which an intervention to change the vitamin D status of mothers during pregnancy can reduce the risk of RSV-associated LRTI in their offspring. An answer to this question would have significant worldwide public health importance given the high prevalence of low vitamin D status worldwide and the high mortality burden accompanying infectious lung diseases in young children. © 2012 International Life Sciences Institute.

    The target group for severe respiratory syncytial virus (RSV) disease prevention is infants under 6 months of age. Vaccine boosting of antibody titres in pregnant mothers could protect these young infants from severe respiratory syncytial virus (RSV) associated disease. Quantifying protective levels of RSV-specific maternal antibody at birth would inform vaccine development. A case control study nested in a birth cohort (2002-07) was conducted in Kilifi, Kenya; where 30 hospitalised cases of RSV-associated severe disease were matched to 60 controls. Participants had a cord blood and 2 subsequent 3-monthly blood samples assayed for RSV-specific neutralising antibody by the plaque reduction neutralisation test (PRNT). Two sample paired t test and conditional logistic regression were used in analyses of log2PRNT titres. The mean RSV log2PRNT titre at birth for cases and controls were not significantly different (P = 0.4) and remained so on age-stratification. Cord blood PRNT titres showed considerable overlap between cases and controls. The odds of RSV disease decreased with increase in log2PRNT cord blood titre. There was a 30% reduction in RSV disease per unit increase in log2PRNT titre (disease. Cord antibody levels show wide variation with considerable overlap between cases and controls. It is likely that, there are additional factors to specific PRNT antibody levels which determine susceptibility to severe RSV disease. In addition, higher levels of neutralizing antibody beyond the normal range may be required for protection; which it is hoped can be achieved by a maternal RSV vaccine.

    Full Text Available Respiratory syncytial virus (RSV is the major cause of acute lower respiratory tract infections in young children, but very little is known about its epidemiology and circulating genotypes in Pakistan. This study analyzed the epidemiological and molecular characteristics of RSV genotypes detected in Pakistani children less than 2 years of age with acute respiratory tract infections (ARIs in a tertiary care hospital in Gilgit Baltistan (GB province during 2011-12 winter season. RSV was detected in 75 out of 105 children presenting with acute respiratory infection. Male infants between 2-6 months age made up the highest percentage of RSV positive cases. Epidemiological factors such as pre-maturity, mean weight, clinical features and diagnosis when compared between RSV positive and negative groups were found to be statistically insignificant. Phylogenetic analysis classified all 75 of the RSV strains into 71 strains of subgroups A and 4 strains of subgroup B, respectively. Strains belonging to subgroups A and B were further subdivided into NA1/GA2 and BA, respectively. The nucleotide and deduced amino acid sequence identities were relatively high among these strains (>90%. Both RSV-A and RSV-B isolates had two potential N-glycosylation sites in HVR2 of G protein and with heavy O-glycosylation of serine and threonine residues (G scores of 0.5-0.7. This report highlights the significance of RSV as a dominant viral etiologic agent of pediatric ARIs, and need for continued molecular epidemiological surveys for early detection of prevalent strains and newly emerging genotypes to understand epidemiology of RSV infections in various regions of Pakistan.

    Full Text Available During the period of neutropenia due to chemotherapy, patients have high risk of infections. The use of antibiotic prophylaxis to reduce neutropenia-related complications in oncologic patients is still disputed. Recent meta-analysis and clinical trials demonstrated that antibiotic prophylaxis with chinolons reduces fever episodes, bacterial infections and mortality in adult oncologic patients with neutropenia due to chemotherapy for acute leukaemia. In paediatric patients, the only randomized, double-blind, prospective study up till now suggested that Amoxicillin clavulanate may represent an effective prophylactic treatment to reduce fever and infections in oncologic children with neutropenia, with an efficacy statistically demonstrated only in patients with acute leukaemia. Considering the risk of resistances, antibiotic-prophylaxis should be used only in selected patients.

    2010-06-01

    Venous thromboembolism (VTE) is rare in children and young adolescents, and occurs predominantly in those with congenital heart disease in whom guidelines exist for VTE prophylaxis. For other paediatric patients, the rarity of the event makes writing an evidence-based clinical practice guideline difficult because each of the known risk factors contributes only a small increase in risk. Thrombophilia screening is controversial because few results assist with prediction of likely thrombosis and may not alter recommendations for prophylaxis. Recent publications highlight the importance of non-pharmacological prevention of VTE in children and adolescents undergoing surgery and the importance of liaison among surgeon, anaesthetist and haematologist. This annotation was written with the aim of collating current evidence for VTE prophylaxis and emphasising the need for further research in vulnerable subgroups.

    Characterization and follow-up evaluation of chest CT of RSV pneumonia in immune-compromised adults during a seasonal epidemic. Retrospective analysis of 132 chest CT examinations of 51 adult immune-compromised patients (29 m/22f, diameter 58 years) with clinical signs of pneumonia and positive RSV test in winter 2011/2012. Two experienced chest radiologists evaluated the morphology (bronchial wall thickening, tree-in-bud, nodules, halo, ground-glass opacities, consolidations, pleural fluid) of the CT scans by consensus. Pathological findings were in 86 % of the chest CT scans: Areas of ground-glass attenuation in 64 %, consolidations in 56 %, nodules in 55 % (diameter 8 mm in maximal diameter, with halo in 71 %), pleural fluid in 44 % (diameter 2 cm), tree-in-bud in 36 %, bronchial wall thickening in 27 % and more than one morphological finding in 72 %. There were no pathological CT findings in 14 % of patients with clinical symptoms of pneumonia because these patients did not undergo follow-up. Radiological progression was found in 45 % of patients and regression in 33 % in follow-up examinations. In 37 % an additional examination of the paranasal sinuses was performed and showed sinusitis in 63 % of cases. 90 % of the patients had sinusitis as well as pneumonia. In addition to RSV, a further pathogenic agent was found in bronchoalveolar lavage of five patients (Aspergillus spec., herpes simplex virus, Pseudomonas aeruginosa). The most characteristic signs in chest CT scans were at the beginning of pneumonia with nodules and tree-in-bud often combined with bronchial wall thickening. The following CT scans showed characteristic but not pathognomonic chest CT findings of RSV pneumonia. These morphological findings should be recognized seasonally (winter) especially at the beginning of the case of pneumonia. RSV-associated additional sinusitis is probably common and should be noticed.

    The indication for the blockade of thyroid gland by the administration of stable iodide is the main countermeasure for diminishing the thyroid uptake of radioiodine following radiological accidents with potential release of radioiodine into the environment in order to avoid deterministic effects and to decrease the probability of stochastic effects. Iodine prophylaxis should be considered along with other countermeasures like sheltering indoors, evacuation and control on contaminated foods. In this communication different factors related to accidental situations regarding iodine prophylaxis are evaluated. A therapeutical scheme is proposed in order to be applied in countries of this region. (author). 4 refs

    Study of iodine prophylaxis following nuclear accidents has been done. Giving stable iodine to a population exposed by I-131 is one of preventive action from internal radiation to the thyroid gland. Stable iodine could be given as Kl tablet in a range of dose of 30 mg/day to 130 mg/day. Improper giving of stable iodine could cause side effect to health, so then some factors should be considered i. e. dose estimation, age, dose of stable iodine to be given, duration of stable iodine prophylaxis and risk of health.

    Available evidence supports the efficacy of pre-exposure prophylaxis (PrEP) in decreasing the incidence of human immunodeficiency virus (HIV) infection among high-risk individuals, especially when used in combination with other behavioural preventive methods. Safety concerns about PrEP present challenges in the implementation and use of PrEP. The aim of this review is to discuss safety concerns observed in completed clinical trials on the use of PrEP. We performed a literature search on PrEP in PubMed, global advocacy for HIV prevention (Aids Vaccine Advocacy Coalition) database, clinical trials registry " http://www.clinicaltrials.gov " and scholar.google, using combination search terms 'pre-exposure prophylaxis', 'safety concerns in the use of pre-exposure prophylaxis', 'truvada use as PrEP', 'guidelines for PrEP use', 'HIV pre-exposure prophylaxis' and 'tenofovir' to identify clinical trials and literature on PrEP. We present findings associated with safety issues on the use of PrEP based on a review of 11 clinical trials on PrEP with results on safety and efficacy as at April 2016. We also reviewed findings from routine real-life practice reports. The pharmacological intervention for PrEP was tenofovir disoproxil fumarate/emtricitabine in a combined form as Truvada ® or tenofovir as a single entity. Both products are efficacious for PrEP and seem to have a good safety profile. Regular monitoring is recommended to prevent long-term toxic effects. The main adverse effects observed with PrEP are gastrointestinal related; basically mild to moderate nausea, vomiting and diarrhea. Other adverse drug effects worth monitoring are liver enzymes, renal function and bone mineral density. PrEP as an intervention to reduce HIV transmission appears to have a safe benefit-risk profile in clinical trials. It is recommended for widespread use but adherence monitoring and real-world safety surveillance are critical in the post-marketing phase to ensure that the benefits

  16. Nuclear detonation, thyroid cancer and potassium iodide prophylaxis

    Full Text Available The recent nuclear disaster at Japan has raised global concerns about effects of radioactive leakage in the environment, associated hazards, and how they can be prevented. In this article, we have tried to explain about the guidelines laid down by World Health Organization for a potassium iodide prophylaxis following a nuclear disaster, and its mechanism of action in preventing thyroid cancer. Data was collected mainly from the studies carried out during the Chernobyl disaster of Russia in 1986 and the hazardous effects especially on the thyroid gland were studied. It was seen that radioactive iodine leakage from the nuclear plants mainly affected the thyroid gland, and especially children were at a higher risk at developing the cancers. Potassium Iodide prophylaxis can be administered in order to prevent an increase in the incidence of thyroid cancers in the population of an area affected by a nuclear disaster. However, one has to be cautious while giving it, as using it without indication has its own risks.

    2016-04-01

    Full Text Available Respiratory Syncytial Virus (RSV is the major cause of pneumonia among infants. Here we elucidated the antibody repertoire following primary RSV infection and traced its evolution through adolescence and adulthood. Whole genome-fragment phage display libraries (GFPDL expressing linear and conformational epitopes in the RSV fusion protein (F and attachment protein (G were used for unbiased epitope profiling of infant sera prior to and following RSV infection. F-GFPDL analyses demonstrated modest changes in the anti-F epitope repertoires post-RSV infection, while G-GFPDL analyses revealed 100-fold increase in number of bound phages. The G-reactive epitopes spanned the N- and C-terminus of the G ectodomain, along with increased reactivity to the central conserved domain (CCD. Panels of F and G antigenic sites were synthesized to evaluate sera from young children (<2 yr, adolescents (14-18 yr and adults (30-45 yr in SPR real-time kinetics assays. A steady increase in RSV-F epitope repertoires from young children to adults was observed using peptides and F proteins. Importantly, several novel epitopes were identified in pre-fusion F and an immunodominant epitope in the F-p27. In all age groups, antibody binding to pre-fusion F was 2-3 folds higher than to post-fusion form. For RSV-G, antibody responses were high following early RSV infection in children, but declined significantly in adults, using either G proteins or peptides. This study identified unlinked evolution of anti-F and anti G responses and supportive evidence for immune pressure driven evolution of RSV-G. These findings could help development of effective countermeasures including vaccines.

    1984-01-01

    A comparison of the late effects on intellectual and neuropsychologic function of three different CNS prophylaxis regimens was conducted in 104 patients treated for childhood acute lymphocytic leukemia. Of the children studied, 33 were randomized to treatment with intrathecal (IT) methotrexate alone, 36 to IT methotrexate plus 2,400 rad cranial irradiation, and 35 to IT methotrexate plus intravenous intermediate dose methotrexate. All patients were in their first (complete) continuous remission, were a minimum of one year post-CNS prophylaxis and had no evidence of CNS disease at the time of evaluation. In contrast to the other two treatment groups, children whose CNS prophylaxis included cranial irradiation attained significantly lower mean Full Scale IQs, performed more poorly on the Wide Range Achievement Test, a measure of school abilities, and exhibited a greater number of difficulties on a variety of other neuropsychologic measures. The poorer performance of the irradiated group was independent of sex of the patient, time since treatment and age at diagnosis. These data suggest that the addition of 2,400 rad cranial irradiation to CNS prophylaxis in ALL puts these children at greater risk for mild global loss in intellectual and neuropsychologic ability

    Glycan heterogeneity of the respiratory syncytial virus (RSV) fusion (F) protein was demonstrated by proteomics. The effect of maturation of the virus glycoproteins-associated glycans on virus infectivity was therefore examined using the α-mannosidase inhibitors deoxymannojirimycin (DMJ) and swainsonine (SW). In the presence of SW the N-linked glycans on the F protein appeared in a partially mature form, whereas in the presence of DMJ no maturation of the glycans was observed. Neither inhibitor had a significant effect on G protein processing or on the formation of progeny virus. Although the level of infectious virus and syncytia formation was not significantly affected by SW-treatment, DMJ-treatment correlated with a one hundred-fold reduction in virus infectivity. Our data suggest that glycan maturation of the RSV glycoproteins, in particular those on the F protein, is an important step in virus maturation and is required for virus infectivity

    This study is the first to link laboratory and hospital data for RSV in England, and therefore the first to describe laboratory-confirmed RSV-associated hospital admissions on a national scale. Our approach to estimate the national incidence of admissions based on developing probability weights from a smaller, linked sample has applications not just for RSV but for other seasonal infections. In addition, with a World Health Organization (WHO consultation last year estimating that an RSV vaccine will be available commercially within 5-10 years, the results of this study can be used in mathematical models of potential vaccine strategy, contributing to the identification of optimal target groups for a potential licensed vaccine.

    Twenty-five percent of all nosocomial infections are wound infections. Professional guidelines support the timely use of preoperative prophylaxis for prevention of postoperative wound infections. Barriers exist in implementing this practice. IPRO, the New York State peer review organization, as part of the Health Care Financing Administration's Health Care Quality Improvement Program, sought to determine the proportion of patients receiving timely antibiotic prophylaxis for aortic grafts, hip replacements and colon resections in 44 hospitals in New York State. IPRO conducted a retrospective medical record review of 44 hospitals through out New York State stratified for teaching, nonteaching status. A sample was drawn of 2651 patients, 2256 from Medicare and 395 from Medicaid, undergoing either abdominal aortic aneurysm repair, partial or total hip replacement or large bowel resection. The study determined the proportion of patients who had documentation of receiving antibiotics and those who received antibiotics timely, that is less than or equal to 2 hours preoperatively. Eighty-six percent of patients had documentation of receiving an antibiotic. Forty-six percent of aneurysm repairs and 60% of hip replacements had evidence of receiving timely antibiotic prophylaxis, that is within 2 hours prior to surgery. For colon resections, 73% of cases had either oral prophylaxis or timely parenteral therapy. An increased proportion of patients had received parenteral antibiotics prematurely as the surgical start time occurred later in the day. A total of 44 different antibiotics were recorded for prophylaxis. Antibiotic prophylaxis was performed in 81% to 94% of cases, however, anywhere from 27% to 54% of all cases did not receive antibiotics in a timely fashion. By delegating implementation of ordered antibiotic prophylaxis to the anesthesia team, timing may be improved and the incidence of postoperative wound infections may decrease.

    Full Text Available Targets for intervention are required for respiratory syncytial virus (RSV bronchiolitis, a common disease during infancy for which no effective treatment exists. Clinical and genetic studies indicate that IL1RL1 plays an important role in the development and exacerbations of asthma. Human IL1RL1 encodes three isoforms, including soluble IL1RL1-a, that can influence IL33 signalling by modifying inflammatory responses to epithelial damage. We hypothesized that IL1RL1 gene variants and soluble IL1RL1-a are associated with severe RSV bronchiolitis.We studied the association between RSV and 3 selected IL1RL1 single-nucleotide polymorphisms rs1921622, rs11685480 or rs1420101 in 81 ventilated and 384 non-ventilated children under 1 year of age hospitalized with primary RSV bronchiolitis in comparison to 930 healthy controls. Severe RSV infection was defined by need for mechanical ventilation. Furthermore, we examined soluble IL1RL1-a concentration in nasopharyngeal aspirates from children hospitalized with primary RSV bronchiolitis. An association between SNP rs1921622 and disease severity was found at the allele and genotype level (p = 0.011 and p = 0.040, respectively. In hospitalized non-ventilated patients, RSV bronchiolitis was not associated with IL1RL1 genotypes. Median concentrations of soluble IL1RL1-a in nasopharyngeal aspirates were >20-fold higher in ventilated infants when compared to non-ventilated infants with RSV (median [and quartiles] 9,357 [936-15,528] pg/ml vs. 405 [112-1,193] pg/ml respectively; p<0.001.We found a genetic link between rs1921622 IL1RL1 polymorphism and disease severity in RSV bronchiolitis. The potential biological role of IL1RL1 in the pathogenesis of severe RSV bronchiolitis was further supported by high local concentrations of IL1RL1 in children with most severe disease. We speculate that IL1RL1a modifies epithelial damage mediated inflammatory responses during RSV bronchiolitis and thus may serve as a

    Full Text Available Abstract Background Respiratory Syncytial Virus (RSV is the leading cause of acute lower respiratory infections (ALRI in children. It is estimated to cause approximately 33.8 million new episodes of ALRI in children annually, 96% of these occurring in developing countries. It is also estimated to result in about 53,000 to 199,000 deaths annually in young children. Currently there are several vaccine and immunoprophylaxis candidates against RSV in the developmental phase targeting active and passive immunization. Methods We used a modified CHNRI methodology for setting priorities in health research investments. This was done in two stages. In Stage I, we systematically reviewed the literature related to emerging vaccines against RSV relevant to 12 criteria of interest. In Stage II, we conducted an expert opinion exercise by inviting 20 experts (leading basic scientists, international public health researchers, international policy makers and representatives of pharmaceutical companies. The policy makers and industry representatives accepted our invitation on the condition of anonymity, due to the sensitive nature of their involvement in such exercises. They answered questions from the CHNRI framework and their “collective optimism” towards each criterion was documented on a scale from 0 to 100%. Results In the case of candidate vaccines for active immunization of infants against RSV, the experts expressed very low levels of optimism for low product cost, affordability and low cost of development; moderate levels of optimism regarding the criteria of answerability, likelihood of efficacy, deliverability, sustainability and acceptance to end users for the interventions; and high levels of optimism regarding impact on equity and acceptance to health workers.

    Thromboembolic events are a post-operative complication of arthroplasty surgery for up to 3 months. The incidence however, is not fully known. Some form of prophylaxis should be provided to all arthroplasty patients. Clinicians are wary of side effects, compliance profile and the associated cost. The objective of this study is to investigate practice patterns and their relevance to 3 risk groups. Ninety questionnaires were sent to orthopaedic surgeons with 3 hypothetical clinical scenarios and 10 prophylaxis regimes for thromboembolism across different risk groups. The response rate was 81\\/90 (90%). The most popular options in all 3 cases were early mobilisation, thrombo-embolism deterrant (TED) stockings and low molecular weight heparin (LMWH) (51\\/81, 62% of all cases). An inconsistent relationship exists between preferred practice and relevant guidelines. Preferred practice does not correlate with each level of risk.

    The prevention of infectious diseases by vaccination and by counselling about malaria prophylaxis is a central aspect of travel medicine. Besides mandatory vaccinations required for entry to certain countries various vaccinations may be indicated depending on destination and type of travel as well as on individual risks of the traveler. In addition, pre-travel counselling should always include a check-up of standard vaccinations. Protection against mosquito bites is the basis of malaria prophylaxis. The addition of chemoprophylaxis is warranted in high risk areas. When regular chemoprophylaxis is not applied it is recommended to carry an appropriate antimalarial drug which can be used for emergency stand-by treatment in case of unexplained fever and when medical attention is not available within 24 hours. Travelers should realize that self-treatment is a first-aid measure and that they should still seek medical advice as soon as possible. © Georg Thieme Verlag KG Stuttgart · New York.

    Despite the common application of dental prophylaxis as part of patient therapy, there is little reported that describes the microbiological impact of this treatment. The authors gave 20 healthy college-aged subjects three dental prophylaxes with a fluoride-containing prophylaxis paste during a two-week period and instructed them in oral hygiene. They evaluated the microbiological composition of dental plaque samples collected before and after treatment using DNA probe analysis. They analyzed 40 representative bacterial species in seven bacterial complexes by checkerboard DNA-DNA hybridization assay techniques. After three dental prophylaxes, the patients' mean Gingival Index score decreased from 0.82 to 0.77, the mean Plaque Index score decreased from 0.72 to zero, and the total number of bacteria per tooth decreased to approximately one-third of the original number. The authors computed two different measures of bacterial presence. The reduction in bacterial numbers was statistically significant and occurred in many species. Bacterial proportion (DNA percentage or percentage of the bacteria per tooth) did not change significantly. Greater reductions in bacterial count occurred in species that showed high numbers before treatment. The total bacterial count decreased by approximately 72 percent of its original level before prophylaxis was initiated. Professional dental prophylaxis did not target any particular bacteria or bacterial groups but removed bacteria nonspecifically and in proportion to their initial numbers. Repeated dental prophylaxes effect a reduction in bacterial amount that is commensurate with the initial amount, but they do does not alter composition. This suggests that mild gingivitis may be a bacterially nonspecific effect of plaque accumulation and emphasizes the need for regular plaque removal to maintain optimal gingival health.

    Oncolytic virotherapy for cancer treatment utilizes viruses for selective infection and death of cancer cells without any adverse effect on normal cells. We previously reported that the human respiratory syncytial virus (RSV) is a novel oncolytic virus against androgen-independent PC-3 human prostate cancer cells. The present study extends the result to androgen-dependent prostate cancer, and explores the underlying mechanism that triggers RSV-induced oncolysis of prostate cancer cells. The oncolytic effect of RSV on androgen-sensitive LNCaP human prostate cancer cells and on androgen-independent RM1 murine prostate cancer cells was studied in vitro in culture and in vivo in a xenograft or allograft tumor model. In vitro, cell viability, infectivity and apoptosis were monitored by MTT assay, viral plaque assay and annexin V staining, respectively. In vivo studies involved virus administration to prostate tumors grown in immune compromised nude mice and in syngeneic immune competent C57BL/6J mice. Anti-tumorogenic oncolytic activity was monitored by measuring tumor volume, imaging bioluminescent tumors in live animals and performing histopathological analysis and TUNEL assay with tumors We show that RSV imposes a potent oncolytic effect on LNCaP prostate cancer cells. RSV infectivity was markedly higher in LNCaP cells compared to the non-tumorigenic RWPE-1 human prostate cells. The enhanced viral burden led to LNCaP cell apoptosis and growth inhibition of LNCaP xenograft tumors in nude mice. A functional host immune response did not interfere with RSV-induced oncolysis, since growth of xenograft tumors in syngeneic C57BL/6J mice from murine RM1 cells was inhibited upon RSV administration. LNCaP cells failed to activate the type-I interferon (IFNα/β)-induced transcription factor STAT-1, which is required for antiviral gene expression, although these cells could produce IFN in response to RSV infection. The essential role of IFN in restricting infection was further

    Biomedical HIV prevention strategies are playing an increasingly prominent role in addressing HIV epidemics globally, but little is known about their use in Japan, where persistent HIV disparities and a recently stable, but not declining, national epidemic indicate the need for evolving approaches. We conducted an ethnographic study to determine the context of pre-exposure prophylaxis (PrEP) and postexposure prophylaxis (PEP) use and to identify directions for future research and action in Japan. We used data from observational fieldwork in the Kansai region and Tokyo Metropolitan Area (n = 178 persons observed), qualitative interviews (n = 32), documents and web-based data sources (n = 321), and email correspondences (n = 9) in the period 2013-2016. Drug approvals by Japan's regulatory agencies, insurance coverage for medications, and policies by healthcare institutions and government agencies were the main factors affecting PrEP and PEP legality, use, and awareness. Awareness and the observable presence of PrEP and PEP were very limited, particularly at the community level. PrEP and PEP held appeal for Japanese scientists and activists, and for study participants who represented various other stakeholder groups; however, significant concerns prevented open endorsements. Japanese health officials should prioritize a national discussion, weigh empirical evidence, and strongly consider formal approval of antiretroviral (ARV) medications for use in PrEP and both occupational and nonoccupational PEP. Once approved, social marketing campaigns can be used to advertise widely and increase awareness. Future research would benefit from theoretical grounding in a diffusion of innovations framework. These findings can inform current and future ARV-based prevention strategies at a critical time in the international conversation.

    Pyelonephritis in infants is considered as a major factor for the formation of renal scar. To prevent recurrent pyelonephritis and renal damage, prophylaxis is extremely important. The aim of this study was to compare the effectiveness of probiotic and antibiotic prophylaxis or no-prophylaxis in infants with pyelonephritis and normal urinary tract. Altogether 191 infants, who were diagnosed with acute pyelonephritis, proven to have normal urinary tracts and followed up for 6 months on prophylaxis, were retrospectively evaluated. According to the types of prophylaxis, the infants were divided into three groups [probiotics (Lactobacillus species), antibiotics (trimethoprim/sulfamethoxazole, TMP/SMX), and noprophylaxis]. The incidence of recurrent urinary tract infection (UTI) during 6 months after the development of pyelonephritis, main causative uropathogens, and its antimicrobial sensitivities were compared. The incidence of recurrent UTI in the probiotic group was 8.2%, which was significantly lower than 20.6% in the no-prophylaxis group (P=0.035) and was not significantly different from 10.0% of the antibiotic group (P=0.532). The significant difference between the probiotic and no-prophylaxis groups was seen only in male infants (P=0.032). The main causative organism of recurrent UTI was Escherichia coli (E.coli), which was not different among the three groups (P=0.305). The resistance rate of E. coli to TMP/SMX was 100% in the antibiotic group, which was significantly higher than 25.0% in the probiotic group and 41.7% in the no-prophylaxis group (P=0.008). Probiotic prophylaxis was more effective in infants with pyelonephritis and normal urinary tract than in those with no-prophylaxis. It could be used as a natural alternative to antibiotic prophylaxis.

    Practice variation regarding perioperative antimicrobial prophylaxis in total artificial heart transplantations (TAH-t) across institutions is unknown. The aim of our survey was to assess the current practices for prevention of infection in TAH-t recipients among different programs. An electronic survey was sent to programs that implant Syncardia TAH (Syncardia Systems, Tuscon, Ariz, USA). Proportions were analyzed for categorical variables; means and SDs were analyzed for continuous variables. The majority of centers (80.8%) had a formal surgical infection prophylaxis protocol. For non-penicillin-allergic patients, five (20.1%) institutions reported using a 4-drug regimen, seven (29.2%) used a 3-drug regimen, five (20.1%) used a 2-drug regimen, and seven (29.2%) used a cephalosporin alone. Similar data was seen in the penicillin-allergic patients. Infections were reported to occur postoperatively in 52.2% centers. During the first month after TAH-t, bacteremia represented 27.3%, driveline infections 27.2%, pulmonary infections 9%, and mediastinal infections 18.2%. The most common organisms seen within the first month were Candida spp., Escherichia coli, and Pseudomonas aeruginosa (21.4%). In 65% of centers, the mean rate of death post-TAH-t due to infection was 14.5% (SD, 22.3%). The mean rate of patients surviving until orthotopic heart transplantation was 58.6% (SD, 27.7%). Preventing infections post-TAH-t is key to decreasing morbidity and mortality. All institutions administered perioperative prophylaxis for TAH-t with significant variation among the centers. The majority of the centers have a formal perioperative prophylactic protocol. Copyright © 2017. Published by Elsevier Inc.

    Plant resistance (R) genes direct recognition of pathogens harboring matching avirluent signals leading to activation of defense responses. It has long been hypothesized that under selection pressure the infidelity of RNA virus replication together with large population size and short generation times results in emergence of mutants capable of evading R-mediated recognition. In this study, the Rsv1/Soybean mosaic virus (SMV) pathosystem was used to investigate this hypothesis. In soybean line PI 96983 (Rsv1), the progeny of molecularly cloned SMV strain G7 (pSMV-G7) provokes a lethal systemic hypersensitive response (LSHR) with up regulation of a defense-associated gene transcript (PR-1). Serial passages of a large population of the progeny in PI 96983 resulted in emergence of a mutant population (vSMV-G7d), incapable of provoking either Rsv1-mediated LSHR or PR-1 protein gene transcript up regulation. An infectious clone of the mutant (pSMV-G7d) was synthesized whose sequences were very similar but not identical to the vSMV-G7d population; however, it displayed a similar phenotype. The genome of pSMV-G7d differs from parental pSMV-G7 by 17 substitutions, of which 10 are translationally silent. The seven amino acid substitutions in deduced sequences of pSMV-G7d differ from that of pSMV-G7 by one each in P1 proteinase, helper component-proteinase, and coat protein, respectively, and by four in P3. To the best of our knowledge, this is the first demonstration in which experimental evolution of a molecularly cloned plant RNA virus resulted in emergence of a mutant capable of evading an R-mediated recognition

    Acute lower respiratory tract infections (ALRIs) caused by respiratory syncytial virus (RSV) are a leading cause of hospitalization in infants. Numerous risk factors have been identified in the aetiology of severe RSV-associated ALRI necessitating hospitalisation, including prematurity and congenital heart disease. Down syndrome (DS), a common genetic disorder associated with congenital and dysmorphic features, has recently been identified as an independent risk factor for RSV-associated ALRI requiring hospitalisation; however, the disease burden of RSV-associated ALRI in this population has not yet been established. Similarly, the impact of DS as an independent risk factor has not yet been quantified. We aimed therefore to estimate the incidence of admissions in children with DS, and by comparing this with unaffected children, to quantify the risk of DS independent of other risk factors. A systematic review of the existing literature published between 1995 and March 1, 2017 was performed to quantify the incidence of hospitalisation due to RSV-associated ALRI in children with DS. Meta-analyses were performed on extracted data using STATA statistical software, and hospitalisation rates for children with and without DS under the age of 2 were calculated. 5 articles were ultimately deemed eligible for analyses. Analyses were limited to children under the age of 2 years. We calculated the hospitalisation rate for children with DS in this age group to be 117.6 per 1000 child-years (95% CI 67.4-205.2), vs a rate of 15.2 per 1000 child-years (95% CI 8.3-27.6) in unaffected children. This indicates DS contributes to a 6.8 (95% CI 5.5-8.4) fold increase in the relative risk of hospitalisation for RSV-associated ALRI. Though limited by a small number of articles, this review found sufficient evidence to conclude DS was a significant independent risk factor for the development of severe RSV-associated ALRI requiring hospitalisation. Further studies are needed to define the

    Full Text Available Human respiratory syncytial virus (RSV is the most significant cause of acute lower respiratory infection in children. However, there is no licensed vaccine available. Here, we investigated the effect of five or 20 copies of C-Class of CpG ODN (CpG-C motif incorporated into a plasmid DNA vaccine encoding RSV fusion (F glycoprotein on the vaccine-induced immune response. The addition of CpG-C motif enhanced serum binding and virus-neutralizing antibody responses in BALB/c mice immunized with the DNA vaccines. Moreover, mice vaccinated with CpG-modified vaccines, especially with the higher 20 copies, resulted in an enhanced shift toward a Th1-biased antibody and T-cell response, a decrease in pulmonary pathology and virus replication, and a decrease in weight loss after RSV challenge. This study suggests that CpG-C motif, cloned into the backbone of DNA vaccine encoding RSV F glycoprotein, functions as a built-in adjuvant capable of improving the efficacy of DNA vaccine against RSV infection.

    Despite a lack of consensus guidelines, local antibiotic administration for prophylaxis of surgical site infections is used during many surgical procedures. The rationale behind this practice is to provide high antibiotic concentrations at the site of surgery while minimizing systemic exposure and adverse effects. Local antibiotic administration for surgical site prophylaxis has inherent limitations in that antibiotics are applied after the incision is made, rather than the current standard for surgical site prophylaxis that recommends providing adequate antibiotic concentrations at the site before the incision. The efficacy and safety of local application of antibiotics for surgical site prophylaxis have been assessed in different types of surgery with a variety of antibiotic agents and methods of application. We identified 22 prospective, randomized, controlled trials that evaluated local application of antibiotics for surgical site prophylaxis. These trials were subsequently divided and analyzed based on the type of surgical procedure: dermatologic, orthopedic, abdominal, colorectal, and cardiothoracic. Methods of local application analyzed included irrigations, powders, ointments, pastes, beads, sponges, and fleeces. Overall, there is a significant lack of level I evidence supporting this practice for any of the surgical genres evaluated. In addition, the literature spans several decades, and changes in surgical procedures, systemic antibiotic prophylaxis, and microbial flora make conclusions difficult to determine. Based on available data, the efficacy of local antibiotic administration for the prophylaxis of surgical site infections remains uncertain, and recommendations supporting this practice for surgical site prophylaxis cannot be made. © 2012 Pharmacotherapy Publications, Inc.

  14. Tetanus: prophylaxis and treatment of the disease.

    Cleansing and debridement is paramount in dealing with tetanus-prone wounds (severe crushing injuries, piercing wounds, blisters and burns are outstanding examples, particularly if contaminated with dirt, grass or other debris). Prophylaxis then is relatively easy in persons who have been actively immunized by toxoid injections. For them, a "booster" injection is indicated. Use of antitoxin, however, is hazardous, whether for prophylaxis or for treatment of the disease. Since it may in itself cause severe disease, including anaphylactic reaction and serum sickness, decision to use it must be weighed against the possibility of the development of tetanus in each case. To prepare for use of it, careful history should be taken, with particular reference to sensitivity to horse dander. Dermal tests, and perhaps ophthalmic tests, for sensitivity to the serum should be carried out. Even the tests may be hazardous and precautions should be taken accordingly. If it is decided that the use of antitoxin is necessary even though the patient is sensitive to the material, desensitization must be carried out promptly, with adequate preparation for severe reaction. There is experimental evidence that antibiotics of the tetracycline group, given soon after injury, may have prophylactic effect against tetanus.

    To present recent advances in stress gastritis prophylaxis in the critically ill and review considerations in selection of a prophylactic agent. Information was obtained from MEDLINE search, reference lists from articles identified in search, and from review articles. Emphasis was placed on controlled trials conducted within the last 5 years. All literature was assessed for methodology, results, and conclusions. Results of prospective, randomized trials, and meta-analyses are summarized. Histamine2-receptor antagonists, antacids, and sucralfate appear equally effective in preventing stress gastritis in the critically ill. A definitive cause-effect relationship between histamine2-receptor antagonists and increased incidence of nosocomial pneumonia has not yet been established. The indications for using a prophylactic agent and consideration in selecting an agent should include an evaluation of the following: risk factors for gastritis including the type of intensive care patient, comparative efficacy, adverse effects, drug interactions, cost, and ease of administration. The least expensive, safest agent requiring minimal monitoring is sucralfate. Prevention of stress gastritis has never been shown to reduce morbidity or mortality significantly. Controversies still exist regarding the need to provide prophylaxis, the choice of an agent, and the relative importance of previously identified risk factors. Further well-designed studies are needed before consensus can be reached.

    The rapid and accurate detection of influenza virus in respiratory specimens is required for optimal management of patients with acute respiratory infections. Because of the variability of the symptoms and the numerous other causes of influenza-like illness, the diagnosis of influenza cannot be made on the basis of clinical criteria alone. Thus, rapid influenza diagnostic tests have been developed such as the Alere i Influenza A&B isothermal nucleic acid assay. We prospectively evaluated the performance of the Alere i Influenza A&B assay in comparison with our routine Xpert Flu/RSV assay. Positive samples were subtyped according to the protocol from the National Influenza Center (Paris, France). A total of 96 respiratory nasal swab samples were analyzed: with both methods, 38 were positive and 56 were negative. Samples were prospectively collected from January 20 to April 8, 2015, from patient (86 adult and 10 pediatric patients) presenting with an influenza-like illness through the French influenza season. In comparison with the Xpert Flu/RSV assay, the overall sensitivity and specificity of the Alere i Influenza A&B assay were 95% and 100%, respectively. Our results indicate that the Alere i Influenza A&B assay has a good overall analytical performance and a high degree of concordance with the PCR-based Xpert Flu/RSV assay. The Alere i Influenza A&B isothermal nucleic acid amplification test is a powerful tool for influenza detection due to its high sensitivity and specificity as well as its ability to generate results within 15min.

    Abstract Objective To review the safety and immunogenicity of pre-exposure rabies prophylaxis (including accelerated schedules, co-administration with other vaccines and booster doses), its cost–effectiveness and recommendations for use, particularly in high-risk settings. Methods We searched the PubMed, Centre for Agriculture and Biosciences International, Cochrane Library and Web of Science databases for papers on pre-exposure rabies prophylaxis published between 2007 and 29 January 2016. We reviewed field data from pre-exposure prophylaxis campaigns in Peru and the Philippines. Findings Pre-exposure rabies prophylaxis was safe and immunogenic in children and adults, also when co-administered with routine childhood vaccinations and the Japanese encephalitis vaccine. The evidence available indicates that shorter regimens and regimens involving fewer doses are safe and immunogenic and that booster intervals could be extended up to 10 years. The few studies on cost suggest that, at current vaccine and delivery costs, pre-exposure prophylaxis campaigns would not be cost-effective in most situations. Although pre-exposure prophylaxis has been advocated for high-risk populations, only Peru and the Philippines have implemented appropriate national programmes. In the future, accelerated regimens and novel vaccines could simplify delivery and increase affordability. Conclusion Pre-exposure rabies prophylaxis is safe and immunogenic and should be considered: (i) where access to postexposure prophylaxis is limited or delayed; (ii) where the risk of exposure is high and may go unrecognized; and (iii) where controlling rabies in the animal reservoir is difficult. Pre-exposure prophylaxis should not distract from canine vaccination efforts, provision of postexposure prophylaxis or education to increase rabies awareness in local communities. PMID:28250534

The relative risk (RR of a bronchiolitis admission was higher among infants with known risk factors for severe RSV infection, including those born preterm (RR = 1.9, 95% CI 1.8-2.0 compared with infants born at term. Other conditions also significantly increased risk of bronchiolitis admission, including Down's syndrome (RR = 2.5, 95% CI 1.7-3.7 and cerebral palsy (RR = 2.4, 95% CI 1.5-4.0.Most (85% of the infants who are admitted to hospital with bronchiolitis in England are born at term, with no known predisposing risk factors for severe RSV infection, although risk of admission is higher in known risk groups. The early age of bronchiolitis admissions has important implications for the potential impact and timing of future active and passive immunisations. More research is needed to explain why babies born with Down's syndrome and cerebral palsy are also at higher risk of hospital admission with RSV bronchiolitis.

  20. Antibiotic prophylaxis in cataract surgery in the setting of penicillin allergy: A decision-making algorithm.

    Science.gov (United States)

    LaHood, Benjamin R; Andrew, Nicholas H; Goggin, Michael

    Cataract surgery is the most commonly performed surgical procedure in many developed countries. Postoperative endophthalmitis is a rare complication with potentially devastating visual outcomes. Currently, there is no global consensus regarding antibiotic prophylaxis in cataract surgery despite growing evidence of the benefits of prophylactic intracameral cefuroxime at the conclusion of surgery. The decision about which antibiotic regimen to use is further complicated in patients reporting penicillin allergy. Historic statistics suggesting crossreactivity of penicillins and cephalosporins have persisted into modern surgery. It is important for ophthalmologists to consider all available antibiotic options and have an up-to-date knowledge of antibiotic crossreactivity when faced with the dilemma of choosing appropriate antibiotic prophylaxis for patients undergoing cataract surgery with a history of penicillin allergy. Each option carries risks, and the choice may have medicolegal implications in the event of an adverse outcome. We assess the options for antibiotic prophylaxis in cataract surgery in the setting of penicillin allergy and provide an algorithm to assist decision-making for individual patients.

    Respiratory syncytial virus (RSV) has been identified as a main cause of hospitalisation in infants and children. To date, the current therapeutic arsenal is limited to ribavirin and palivizumab with variable efficacy. In this work, starting from a number of in-house series of previously described anti-RSV agents based on the benzimidazole scaffold, with the aim at gaining a better understanding of the related chemical features involved in potency and safety profiles, we applied a computational study including two focussed comparative molecular fields analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). The results allowed us to derive useful suggestions for the design of derivatives and also to set up statistical models predicting the potency and selectivity index (SI = CC 50 /EC 50 ) of any new analogue prior to synthesis. Accordingly, here, we discuss preliminary results obtained through the applied exhaustive QSAR analyses, leading to design and synthesise more effective anti-RSV agents.

    Full Text Available Background A better understanding of respiratory syncytial virus (RSV epidemiology requires realistic estimates of RSV shedding patterns, quantities shed, and identification of the related underlying factors. Methods RSV infection data arise from a cohort study of 47 households with 493 occupants, in coastal Kenya, during the 2009/2010 RSV season. Nasopharyngeal swabs were taken every 3 to 4 days and screened for RSV using a real time polymerase chain reaction (PCR assay. The amount of virus shed was quantified by calculating the ‘area under the curve’ using the trapezoidal rule applied to rescaled PCR cycle threshold output. Multivariable linear regression was used to identify correlates of amount of virus shed. Results The median quantity of virus shed per infection episode was 29.4 (95% CI: 15.2, 54.2 log10 ribonucleic acid (RNA copies * days. Young age (<1 year, presence of upper respiratory symptoms, intra-household acquisition of infection, an individual’s first infection episode in the RSV season, and having a co-infection of RSV group A and B were associated with increased amount of virus shed. Conclusions The findings provide insight into which groups of individuals have higher potential for transmission, information which may be useful in designing RSV prevention strategies.

    The primary objective of this guideline is to assist the practitioner in choosing an appropriate prophylactic medication for an individual with migraine, based on current evidence in the medical literature and expert consensus. This guideline is focused on patients with episodic migraine (headache on ≤ 14 days a month). Through a comprehensive search strategy, randomized, double blind, controlled trials of drug treatments for migraine prophylaxis and relevant Cochrane reviews were identified. Studies were graded according to criteria developed by the US Preventive Services Task Force. Recommendations were graded according to the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group. In addition, a general literature review and expert consensus were used for aspects of prophylactic therapy for which randomized controlled trials are not available. Prophylactic drug choice should be based on evidence for efficacy, side-effect profile, migraine clinical features, and co-existing disorders. Based on our review, 11 prophylactic drugs received a strong recommendation for use (topiramate, propranolol, nadolol, metoprolol, amitriptyline, gabapentin, candesartan, butterbur, riboflavin, coenzyme Q10, and magnesium citrate) and 6 received a weak recommendation (divalproex sodium, flunarizine, pizotifen, venlafaxine, verapamil, and lisinopril). Quality of evidence for different medications varied from high to low. Prophylactic treatment strategies were developed to assist the practitioner in selecting a prophylactic drug for specific clinical situations. These strategies included: first time strategies for patients who have not had prophylaxis before (a beta-blocker and a tricyclic strategy), low side effect strategies (including both drug and herbal/vitamin/mineral strategies), a strategy for patients with high body mass index, strategies for patients with co-existent hypertension or with co-existent depression and /or

    Full Text Available Only sporadic reports of failure of post-exposure prophylaxis for rabies exist in the published literature. We are reporting such a case in a 3-year-old boy. The child had Category III dog bite on his right thigh. He presented with progressive ascending paralysis, finally developing quadriplegia and respiratory paralysis. Typical hydrophobia and aerophobia were absent. He received four doses of antirabies cell culture vaccine. He did not receive antirabies immunoglobulin. The boy succumbed on the 23 rd day of the dog bite. Diagnosis of rabies was confirmed in the laboratory by demonstration of Negri bodies, direct fluorescent antibody test and reverse transcriptase-polymerase chain reaction either on impression smear of brain or a piece of brain taken during autopsy.

  5. [Surgical site infections: antibiotic prophylaxis in surgery].

    2014-01-01

    Surgical site infections (SSI) are very common, and represent more than 20% of all hospital-acquired infections. SSIs are associated with a higher mortality, as well as to an extended hospital stay and costs, depending on the surgical procedure and type of SSI. Advances in control practices for these infections include improvement in operating room ventilation, sterilization methods, barriers, and surgical techniques, as well as in surgical antimicrobial prophylaxis. For the latter, the antimicrobial agent should: be active against the most common pathogens, be administered in an appropriate dosage and in a time frame to ensure serum and tissue concentrations over the period of potential contamination, be safe, and be administered over the shortest effective time period to minimize adverse events, development of resistances, and cost.

    To evaluate the azithromycin effects alone and in combination with other agents in the prophylaxis and treatment of murine toxoplasmosis. A total of 280 BALB/c mice were included, and 2 x 103 Toxoplasma organisms of the RH strain Toxoplasma gondii strain ATCC50174 were given intraperitoneally to each mouse. In experiment one, 40 animals were given azithromycin 200 milligram/kilogram/daily for 3 days starting the day of inoculation, 40 mice were control. In experiment 2, the treatment was started 48 hours after inoculation and given daily for 3 days: one group received azithromycin 200 milligram/kilogram/day, the second group received pyrimethamine 25 milligram/kilogram/day, and the sulfadiazine 100 milligram/kilogram/day. The third group was control. In experiment 3, 7 groups of animals received one of the following (1) none, (2) azithromycin 200 milligram/kilogram/day, (3) pyrimethamine 25 milligram/kilogram/day and sulfadiazine 100 milligram/kilogram/day, (4) azithromycin and sulfadiazine, (5) azithromycin and pyrimethamine, (6) azithromycin with sulfadiazine and pyrimethamine, (7) sulfadiazine alone. Treatment was initiated 72 hours after inoculation for 3 days. The study was conducted at the Animal Care Facility of King Saud University, Riyadh, Kingdom of Saudi Arabia. Animals that received azithromycin simultaneously with inoculation survived, and all control animals died. All animals died in groups receiving single drug therapy. Animals treated with azithromycin and sulfadiazine showed a survival rate of 40%, sulfadiazine and pyrimethamine 40%, or azithromycin with sulfadiazine and pyrimethamine 95% (p<0.0001). Azithromycin alone was found to be effective in the prophylaxis of murine toxoplasmosis. Combination therapy was effective in the treatment of murine toxoplasmosis.

  7. Infective Endocarditis in Children — New Approach in Antimicrobial Prophylaxis

    2016-06-01

    Full Text Available Infective endocarditis (IE is an infection of the endocardium and/or heart valves with the formation of a thrombus and secondary damage of the involved tissue, with significant mortality and severe complications. The prevention of bacterial endocarditis is of great controversy. Antimicrobial prophylaxis is usable in the prevention of endocarditis by killing bacteria before or after their extension to the damaged endocardium. No human studies offer strong evidence to support the efficacy of antibiotic prophylaxis so far, thus it could be potentially dangerous. Therefore, the European Society of Cardiology (ESC may need to reconsider and update the previous guidelines with the proposal of reducing the prophylactic approach of IE. The 2015 Task Force recommends prophylaxis for highest risk patients undergoing highest risk procedures, focused on prevention rather than prophylaxis of IE, especially in nosocomial endocarditis.

A retrospective chart review was conducted from June, 2007 through June, 2008 of 151 women who were prescribed antiretroviral prophylaxis by protocol. All women receiving HIV prophylaxis initially screened HIV seronegative. Of the 58 women who reported taking any HIV prophylaxis, 36 (62% were HIV screened at 12 and/or 24 weeks and none had HIV seroconverted. Although the initiation of an HIV post exposure prophylaxis protocol for sexual assault in a county hospital population is feasible, patient follow-up for counseling and HIV serostatus evaluation is an identified barrier

    Full Text Available We conducted a retrospective case series study to evaluate the safety of fosfluconazole prophylaxis for preventing invasive fungal infection in VLBW infants with a central vascular access. Fosfluconazole was administered intravenously at a dose of 6 mg/kg everyday during which time a central venous catheter was placed. A total of 23 infants met the criteria for enrollment in our study. No cases of fungal infection were detected during the central venous catheter placement in the group. None of the infants had an elevated β-D-glucan, and all of them were still alive at discharge. Regarding the liver and renal function, no statistically significant differences were observed before and at the end of fosfluconazole prophylaxis. The results of this study demonstrate that fosfluconazole prophylaxis in preventing invasive fungal infection was well tolerated by VLBW infants. This is a first report to describe antifungal prophylaxis using fosfluconazole for VLBW infants.

    Although preventable, venous thromboembolism remains a common cause of hospital acquired morbidity and mortality. Guidelines, such as the one produced by the American College of Chest Physicians (ACCP), are aimed at reducing hospital associated venous thromboemboli. Unfortunately the majority of studies have revealed inadequate adherence to these guidelines. The objective of this study was to evaluate the use of venous thromboembolism prophylaxis at Cork University Hospital. Cork University Hospital, Wilton, Cork, Ireland. Data from the patient's chart, drug kardex and laboratory results were recorded during April 2010. A Caprini score, a venous thromboembolism risk factor assessment tool, was subsequently calculated for each patient based on data collected. Appropriate prophylaxis was determined after examining data collected, Caprini score and prophylactic regime according to the ACCP 8th edition guidelines. Primary outcome was to analyse adherence to VTE prophylaxis guidelines. A total of 394 patients met the inclusion criteria and were reviewed, of which, 60% (n = 236) were medical and 37% (n = 146) were surgical patients. In total 63% of patients received some form of venous thromboembolism prophylaxis. Furthermore, 54% of medical and 76% of surgical patients received prophylaxis. However only 37% of the patients studied received appropriate thromboprophylaxis according to the ACCP 8th edition guidelines (Geerts et al. in chest 133(6 Suppl):381S-453S, 2008). Additionally 51% of surgical and 27% of medical patients received appropriate prophylaxis. Data collected from Cork University Hospital revealed poor adherence to international venous thromboembolism prophylaxis guidelines. As stated in the ACCP 8th edition guidelines, every hospital should develop a formal strategy for venous thromboembolism prevention (Geerts et al. in chest 133(6 Suppl):381S-453S, 2008). In order to improve adherence to guidelines, Cork University Hospital should develop, implement and

    2006-01-01

    We have previously shown that peroxisome proliferator-activated receptor-γ (PPARγ) agonists inhibited the inflammatory response of RSV-infected human lung epithelial cells. In this study, we supply evidence that specific PPARγ agonists (15d-PGJ 2 , ciglitazone, troglitazone, Fmoc-Leu) efficiently blocked the RSV-induced cytotoxicity and development of syncytia in tissue culture (A549, HEp-2). All PPARγ agonists under study markedly inhibited the cell surface expression of the viral G and F protein on RSV-infected A549 cells. This was paralleled by a reduced cellular amount of N protein-encoding mRNA determined by real-time RT-PCR. Concomitantly, a reduced release of infectious progeny virus into the cell supernatants of human lung epithelial cells (A549, normal human bronchial epithelial cells (NHBE)) was observed. Similar results were obtained regardless whether PPARγ agonists were added prior to RSV infection or thereafter, suggesting that the agonists inhibited viral gene expression and not the primary adhesion or fusion process

    Full Text Available Worldwide, respiratory syncytial virus (RSV is considered to be the most important viral cause of respiratory morbidity and mortality among infants and young children. Although no active vaccine is available on the market yet, there are several active vaccine development programs in various stages. To assess whether one of these vaccines might be a future asset for national immunization programs, modeling the costs and benefits of various vaccination strategies is needed.To evaluate the potential cost-effectiveness of RSV vaccination of infants and/or pregnant women in Turkey.A multi-cohort static Markov model with cycles of one month was used to compare the cost-effectiveness of vaccinated cohorts versus non-vaccinated cohorts. The 2014 Turkish birth cohort was divided by twelve to construct twelve monthly birth cohorts of equal size (111,459 new-borns. Model input was based on clinical data from a multicenter prospective study from Bursa, Turkey, combined with figures from the (international literature and publicly available data from the Turkish Statistical Institute (TÜÏK. Incremental cost-effectiveness ratios (ICERs were expressed in Turkish Lira (TL per quality-adjusted life year (QALY gained.Vaccinating infants at 2 and 4 months of age would prevent 145,802 GP visits, 8,201 hospitalizations and 48 deaths during the first year of life, corresponding to a total gain of 1650 QALYs. The discounted ICER was estimated at 51,969 TL (26,220 US $ in 2013 per QALY gained. Vaccinating both pregnant women and infants would prevent more cases, but was less attractive from a pure economic point of view with a discounted ICER of 61,653 TL (31,106 US $ in 2013 per QALY. Vaccinating only during pregnancy would result in fewer cases prevented than infant vaccination and a less favorable ICER.RSV vaccination of infants and/or pregnant women has the potential to be cost-effective in Turkey. Although using relatively conservative assumptions, all evaluated

    Francesco Napolitano

    Full Text Available BACKGROUND: The appropriate use of antibiotics prophylaxis in the prevention and reduction in the incidence of surgical site infection is widespread. This study evaluates the appropriateness of the prescription of antibiotics prophylaxis prior to surgery amongst hospitalized patients in the geographic area of Avellino, Caserta, and Naples (Italy and the factors associated with a poor adherence. METHODS: A sample of 382 patients admitted to 23 surgical wards and undergoing surgery in five hospitals were randomly selected. RESULTS: Perioperative antibiotic prophylaxis was appropriate in 18.1% of cases. The multivariate logistic regression analysis showed that patients with hypoalbuminemia, with a clinical infection, with a wound clean were more likely to receive an appropriate antibiotic prophylaxis. Compared with patients with an American Society of Anesthesiologists (ASA score ≥4, those with a score of 2 were correlated with a 64% reduction in the odds of having an appropriate prophylaxis. The appropriateness of the timing of prophylactic antibiotic administration was observed in 53.4% of the procedures. Multivariate logistic regression model showed that such appropriateness was more frequent in older patients, in those admitted in general surgery wards, in those not having been underwent an endoscopic surgery, in those with a higher length of surgery, and in patients with ASA score 1 when a score ≥4 was chosen as the reference category. The most common antibiotics used inappropriately were ceftazidime, sultamicillin, levofloxacin, and teicoplanin. CONCLUSIONS: Educational interventions are needed to improve perioperative appropriate antibiotic prophylaxis.

    While primary prophylaxis is a well-established and recommended method of care delivery for children with severe haemophilia, fewer studies have documented the benefits of secondary prophylaxis started in adolescence or adulthood. To evaluate the role of secondary prophylaxis started in adolescent and adult severe haemophiliacs, a retrospective observational cohort study was conducted in 10 Italian Centres that investigated 84 haemophiliacs who had bled frequently and had thus switched from on-demand to prophylactic treatment during adolescence (n = 30) or adulthood (n = 54). The consumption of clotting factor concentrates, the orthopaedic and radiological scores, quality of life and disease-related morbidity were compared before and after starting secondary prophylaxis. Prophylaxis reduced the mean annual number of total and joint bleeds (35.8 vs. 4.2 and 32.4 vs. 3.3; P work/school (34.6 vs. 3.0, P life. With respect to on-demand treatment, higher factor consumption and cost of secondary prophylaxis were balanced by marked clinical benefits and greater well-being in this cohort of adolescent/adult haemophiliacs.

This is a systematic review with search at databases: PubMed, Capes Portal, Virtual Health Library (BVS - Biblioteca Virtual em Saúde)/Lilacs, Scopus and Cochrane. The keywords used were: "Antifungal", "Candida" "Fluconazole prophylaxis" and "Preterm infants". Invasive Candidiasis was evaluated in all the twelve items. In eleven of them, there was a statistically significant difference between the groups receiving prophylactic fluconazole, with lower frequency of Invasive Candidiasis, compared to placebo or no prophylaxis group. Colonization by Candida species was also evaluated in five studies; four of them presented statistically lower proportion of colonization in patients with Fluconazole prophylaxis, compared to placebo or no drugs. In one study, there was a significant difference, favoring the use of fluconazole, and reduction of death. Studies indicate the effectiveness of prophylaxis with fluconazole, with reduction in the incidence of colonization and invasive fungal disease. The benefits of prophylaxis should be evaluated considering the incidence of candidiasis in the unit, the mortality associated with candidiasis, the safety and toxicity of short and long-term medication, and the potential for development of resistant pathogens.

    Migraine prophylaxis is a stepwise procedure with lifestyle advice followed by consideration of medications. Patients should be advised to try to maintain a regular lifestyle, with regular sleep, meals, exercise, and management of stress, perhaps through relaxation techniques or other ways that are sensible for them. If this regimen does not adequately control their migraines, preventatives are indicated. Patients can choose between evidence-based nutraceuticals such as riboflavin, feverfew, butterbur, or coenzyme Q10, or more traditional pharmacotherapeutics. Medicine choices are somewhat limited by what is available in each country, but from the full range, the medicines of first choice are beta-adrenoceptor blockers, flunarizine, topiramate, and valproic acid. Beta-adrenoceptor blockers are particularly useful in patients also suffering from hypertension or tachycardia. Following recent studies, topiramate has become a first choice for episodic as well as chronic migraine. It is the only prophylactic drug that may lead to weight loss, but it is sometimes associated with adverse cognitive effects. Valproic acid and flunarizine also have very good prophylactic properties. However, valproic acid is often associated with adverse effects, and flunarizine is unavailable in many countries, including the United States. If sequential monotherapies are ineffective, combinations of first-line drugs should be tried before advancing to drugs of second choice, which are associated with more adverse effects or have less well-established prophylactic properties. Amitriptyline should be used carefully because of its anticholinergic effects, although it is useful in comorbid tension-type headache, depression, and sleep disorders. Methysergide is very effective, but it has been supplanted or even made unavailable in many countries because of its well-described association with retroperitoneal fibrosis. Pizotifen has a slightly better safety profile but is unavailable in the United

    Aim: To describe computed tomography (CT)-imaging findings in human metapneumovirus (HMPV)-related pulmonary infection as well as their temporal course and to analyze resemblances/differences to pulmonary infection induced by the closely related respiratory-syncytial-virus (RSV) in immunocompromised patients. Materials and methods: Chest-CT-scans of 10 HMPV PCR-positive patients experiencing pulmonary symptoms were evaluated retrospectively with respect to imaging findings and their distribution and results were then compared with data acquired in 13 patients with RSV pulmonary infection. Subsequently, we analyzed the course of chest-findings in HMPV patients. Results: In HMPV, 8/10 patients showed asymmetric pulmonary findings, whereas 13/13 patients with RSV-pneumonia presented more symmetrical bilateral pulmonary infiltrates. Image analysis yielded in HMPV patients following results: ground-glass-opacity (GGO) (n = 6), parenchymal airspace consolidations (n = 5), ill-defined nodular-like centrilobular opacities (n = 9), bronchial wall thickening (n = 8). In comparison, results in RSV patients were: GGO (n = 10), parenchymal airspace consolidations (n = 9), ill-defined nodular-like centrilobular opacities (n = 10), bronchial wall thickening (n = 4). In the course of the disease, signs of acute HMPV interstitial pneumonia regressed transforming temporarily in part into findings compatible with bronchitis/bronchiolitis. Conclusions: Early chest-CT findings in patients with HMPV-related pulmonary symptoms are compatible with asymmetric acute interstitial pneumonia accompanied by signs of bronchitis; the former transforming with time into bronchitis and bronchiolitis before they resolve. On the contrary, RSV-induced pulmonary infection exhibits mainly symmetric acute interstitial pneumonia.

    Infants with RSV infections have been found to have a clinically significant rate of urinary tract infections (UTIs). The American Academy of Pediatrics (AAP) published a revised Clinical Practice Guideline on UTIs in 2011, which includes major changes in diagnostic criteria for UTIs. Past research has been done using previous diagnostic criteria. The objective of the study is to assess the rate of UTIs in febrile infants with respiratory syncytial virus (RSV) infections according to the 2011 revised AAP Diagnostic Criteria and compare the rate of UTIs against the 1999 AAP Diagnostic Criteria. A retrospective comparative study of febrile infants (2-12 months) with RSV infections admitted to the Inpatient Pediatric unit of Lincoln Medical and Mental Center, Bronx, NY, from September through April 2006 to 2012. We applied the AAP's 1999 and 2011 diagnostic criteria for UTIs separately to assess the rates of UTIs. A total of 359 RSV-positive febrile patients who were investigated for UTIs were enrolled. Pyuria was found in 11.1% (40/359), positive urine culture 10 000 to 50 000 was found in 1.4% (5/359) and ≥50 000 in 4.7% (17/359). The rate of UTIs using AAP's 1999 criteria was 6.1% (22/359), and using the 2011 criteria the rate was 1.1% (4/359). The rate of UTIs was significantly different between the 2 groups (odds ratio [confidence interval] = 0.17 [0.05, 0.5], P = .001). The rate of UTIs in RSV-positive febrile infants is very low (1.1%) with the 2011 AAP diagnostic criteria. Previously described increased risk of UTIs may represent asymptomatic bacteriuria or contaminated specimens. © The Author(s) 2014.

    Venous thromboembolism remains the most common cause of hospital readmission and death after total joint arthroplasty. The 2008 American College of Chest Physicians (ACCP) guidelines, based on prospective randomized clinical trials with a venography endpoint, endorse the use of low-molecular-weight heparin, fondaparinux, or adjusted dose warfarin (target international normalized ratio, 2.5; range, 2-3) for up to 35 days after total hip arthroplasty (THA) and total knee arthroplasty (TKA). In the past, the ACCP has recommended against the use of aspirin, graduated compression stockings, or venous compression devices as the sole means of prophylaxis, but in 2008 they first recommended the "optimal use of mechanical thromboprophylaxis with venous foot pumps or intermittent pneumatic compression devices" in patients undergoing total joint arthroplasty who "have a high risk of bleeding." When the high risk subsides, pharmacologic thromboprophylaxis is substituted for, or added to, mechanical methods. Fractionated heparins and pentasaccharide are the most effective agents in reducing venographic deep venous thrombosis (DVT) after total joint arthroplasty with residual clot rates rates. Low-intensity warfarin (target international normalized ratio, 2.0) combines safety (bleeding rates exchange for a lower bleeding rate; genetic testing will likely simplify warfarin use and reduce outlier responders.

    To find out the incidence of surgical site infection in clean general surgery cases operated without prophylactic antibiotics. One hundred and twenty-four clean surgical cases operated without antibiotic prophylaxis between July 2003 and December 2004, were studied and these were compared with similar number of cases who received antibiotics. The data was collected and analyzed using software SPSS (version 10.0). Chi-square and student-t test were used to analyze the association between antibiotics and wound infection. The most frequent operation was repair of various hernias, 69.3% in group A and 75% in group B. More operations were carried out between 21-30 years, 38.7% in group A and 41.9% in group B. Surgical site infection occurred in one patient (0.8%) in each group. Chi-square test (0.636) applied to group A and B showed no association of infection and administration/ no administration of antibiotics (p > 0.25). The t-test applied on group A and B (t=0) also showed no significant difference between administration of antibiotics/ no-antibiotics and infection (p > 0.25). The use of prophylactic antibiotic in clean, non implant and elective cases is unnecessary. (author)

    Full Text Available Abstract Background Both prophylaxis and treatment of venous thromboembolism (VTE: deep venous thrombosis (DVT and pulmonary emboli (PE with anticoagulants are associated with significant risks of major and fatal hemorrhage. Anticoagulation treatment of VTE has been the standard of care in the USA since before 1962 when the U.S. Food and Drug Administration began requiring randomized controlled clinical trials (RCTs showing efficacy, so efficacy trials were never required for FDA approval. In clinical trials of 'high VTE risk' surgical patients before the 1980s, anticoagulant prophylaxis was clearly beneficial (fatal pulmonary emboli (FPE without anticoagulants = 0.99%, FPE with anticoagulants = 0.31%. However, observational studies and RCTs of 'high VTE risk' surgical patients from the 1980s until 2010 show that FPE deaths without anticoagulants are about one-fourth the rate that occurs during prophylaxis with anticoagulants (FPE without anticoagulants = 0.023%, FPE while receiving anticoagulant prophylaxis = 0.10%. Additionally, an FPE rate of about 0.012% (35/28,400 in patients receiving prophylactic anticoagulants can be attributed to 'rebound hypercoagulation' in the two months after stopping anticoagulants. Alternatives to anticoagulant prophylaxis should be explored. Methods and Findings The literature concerning dietary influences on VTE incidence was reviewed. Hypotheses concerning the etiology of VTE were critiqued in relationship to the rationale for dietary versus anticoagulant approaches to prophylaxis and treatment. Epidemiological evidence suggests that a diet with ample fruits and vegetables and little meat may substantially reduce the risk of VTE; vegetarian, vegan, or Mediterranean diets favorably affect serum markers of hemostasis and inflammation. The valve cusp hypoxia hypothesis of DVT/VTE etiology is consistent with the development of VTE being affected directly or indirectly by diet. However, it is less consistent with

    Despite an increased understanding of the pathogenesis of NP and advances in diagnosis and treatment, the risk, cost, morbidity, and mortality of NP remain unacceptably high. This article has identified strategic areas for primary and secondary prophylaxis that are simple and cost-effective. Realizing that the pathogenesis of NP requires bacterial colonization and the subsequent entry of these bacteria into the lower respiratory tree helps highlight the role of cross-infection and the importance of standard infection control procedures. Similarly the role of sedation and devices as risk factors can be reduced by minimizing the duration and intensity of sedation and length of exposure to invasive devices. Additional low-cost interventions that have been shown to be effective in preventing NP are the positioning of patients in a semirecumbent position and the appropriate use of enteral feeding, antibiotics, and selected medical devices. Prophylaxis of NP and VAP is carried out best by a multidisciplinary management team comprised of physicians (critical care, pulmonary medicine, infectious diseases, and primary care), critical care and infection control nurses, and respiratory therapists, even though this approach may result in decreased professional autonomy and freedom. This group should review the current guidelines, pathways, and standards for short-term and long-term prophylaxis of NP and VAP, then integrate them into and monitor their use for routine patient care. The risk factors and prophylaxis strategies for NP discussed in this article apply primarily to patients in acute care facilities, but also are relevant to alternative health care settings as well as the care of ill patients in ambulatory settings. The routine use of effective team policies for prophylaxis needs to be monitored by the Joint Commission for the Accreditation of Health Care or other agencies.

    The spectrum of bleeding problems in FVII deficiency is highly variable and FVII levels and causative genetic mutations correlate poorly with the bleeding risk. Long-term prophylaxis is generally initiated in order to prevent subsequent CNS bleeding after a first event or in patients with other major/ life threatening/ frequent bleeding symptoms as gastrointestinal bleeding or hemarthrosis. However few data are available in the literature regarding FVII prophylaxis and clinical decisions cannot be based on evidence. We report the data available in the literature on FVII prophylaxis and our personal experience regarding three patients affected by severe FVII deficiency. Specific papers on long-term prophylaxis in severe FVII deficiency were identified using the database, PUBMED. The most frequent indications for long-term prophylaxis were CNS bleeding (58%), hemartrosis (15%) and GI bleeding (9%). Patients were treated with various dosages and frequency. Prophylactic treatment with 10-30U/kg (pdFVII) or 20-30mcg/kg (rFVIIa) twice or three times/weeks was described to be effective. In the literature and in our experience, prophylaxis can be considered in patients with severe FVII deficiency and severe bleeding phenotype. A dose of 10-30U/kg (pdFVII) or 20-30 microg/kg (rFVIIa) twice or three times/week is usually administrated, but dose and frequency can be tailored based on the clinical follow-up of the patients. Since hemarthrosis is a frequent manifestation, a suggestion to improve the outcomes of patients with severe FVII deficiency is to monitor joint condition in order to identify early arthropathy that could be another indication to start secondary prophylaxis. © 2015 John Wiley & Sons Ltd.

    Controversies about global clinical trials, particularly HIV trials, tend to be framed in terms of ethics. In this article, I explore debates about ethics in the Cambodia Pre-Exposure Prophylaxis trial, which was designed to test the safety and efficacy of tenofovir as a prevention for HIV infection. Bringing together studies of public participation in science with studies of bioethics, I show how activists around the Cambodian Pre-Exposure Prophylaxis trial circulated and provoked debates about standards of research ethics, as opposed to research methodology. This postcolonial bioethics was configured through the circulation of and debate about ethics guidelines, and historically and culturally specific relations of vulnerability and responsibility between foreigners and Cambodians and between Cambodian leaders and Cambodian subjects. I argue that this shift in the object of ethical concern, from the experimental human subject to the relation between subjects and researchers, illustrates how a postcolonial field of articulation reformulates classical bioethics.

    This study will present trends and recommendations to increase active and passive safety in paragliding on the basis of current state-of-the-art equipment and typical patterns of injury. This German-Swiss teamwork presents data of 55 male and 9 female patients treated after paragliding accidents between 1994 to 1998 respectively 1996 to 1998. 43.7% of the pilots presented with multiple injuries, 62.5% suffered spinal fractures and 18.8% pelvic fractures. 28.4% of the injured pilots were admitted with injuries of the lower extremities mainly affecting the tarsus or the ankle joint. Only three patients with single injuries could be treated in an ambulatory setting. 54.0% of the injuries left the patients with lasting functional residues and complaints. Main causes of accidents were either pilot error in handling the paraglider or general lack of awareness about potential risk factors. 46.0% of injuries occurred during landing, 42.9% of injuries during the flight and another 11.1% of injuries during starting procedures. With noticeable enhanced performance sails of the beginners and intermediate level are increasingly popular. Protective helmets and sturdy footwear reaching above the ankle joint are indispensable pieces of equipment. The use of protective gloves is highly recommended. Back protection devices of the new generation provide the best passive prophylaxis for the pilot against pelvic and spinal cord injuries. This area hold the most promise for increasing safety and reducing risk of injury in future, apart from using beginners and intermediate wings. After acquisition of the pilot license performance and security training provide the best preparing to master unforeseeable situations.

    Full Text Available Background and Aims: Despite advances in trauma management, treatment of the consequent infections has remained a major challenge. Antibiotic prophylaxis has been widely applied to reduce such infections. Although bacteria are present in most body parts, severe infections after treatment are less frequent in the head and neck of healthy individuals. The aim of the present study was to review the reasonable application of antibiotic prophylaxis in maxillofacial trauma. Materials and Methods: In this review article, PubMed and Google Scholar databases were searched for studies on antibiotic prophylaxis in maxillofacial trauma published during 2000-2014. Conclusion: Antibiotics were not prescribed for tears and small clean wounds in the face and mouth. However, prophylaxis was applied for extensive mouth injuries which involved the facial skin. In case of maxillofacial fractures, 24-hour administration of antibiotics sufficed for compound fractures of the mandible and other parts of the face. Antibiotics were not required in other types of fractures. Prophylaxis should be applied over short pre- or post-operative periods based on the severity and complexity of maxillofacial fractures and their relations with intra- and extraoral environments. Apparently, more detailed studies are warranted to further clarify the subject.

    INTRODUCTION. Antimicrobial prophylaxis decreases the surgical infections, but its indiscriminate use to favors the increment of infection rates and the bacterial resistance is much more probable in presence of antibiotics. The aim of present research was to evaluate the results of antibiotic prophylaxis in the otorhinolaryngology elective major surgery. METHODS. A retrospective-descriptive research was made on the prophylactic use of antibiotics in this type of surgery in the Otorhinolaryngology Service of the ''Comandant Manuel Fajardo'' during 6 years (2001-2006). Sample included 661 patients and the following variables were studied: sex, age and therapeutic response criteria (satisfactory and non-satisfactory). According to the intervention complexity oral antibiotic or parenteral prophylaxis was administered carrying out a surgical hound site culture. RESULTS. There was a predominance of male sex (54,1%) and the 31 and 62 age group. The 41,90% of patients operated on required antibiotic prophylaxis. The was a 7,9% of surgical wound infections. The more frequent microorganisms were Pseudomonas aeruginosa, Enterobacter and Escherichia. In head and neck oncology surgeries infection average was high (42,3%). Torpid course was due to concurrence of infection risk factors. There were neither adverse events nor severe complications. CONCLUSIONS. In Otorhinolaryngology, antimicrobial prophylaxis works against a wide variety of microorganisms but not in the Oncology surgeries. (author)

    Full Text Available Transurethral Ureterolithotripsy (TUL is a frequently used procedure in urology departments. Many urologists perform TUL without antibiotic prophylaxis; however the use of chemoprophylaxis before TUL remains a controversial issue in urology. Thisstudy was carried out to assess the safety of omitting antibiotic prophylaxis prior to TUL. In a prospective randomized clinical trial from January 2005 to December 2007, 114 patients with ureteral stones were enrolled; Fifty seven had preoperative antibiotic prophylaxis administered before TUL and fifty seven patients underwent TUL without antibiotic prophylaxis. The rate of postoperative infectious complications (fever, positive blood culture, significant bactriuria, the length of hospital stay and overall stone free rate were compared between the two groups. There was no statistically significant difference between two groups in the operation time, length of hospital stay, postoperative bacteriuria, positive urine culture, postoperative fever and overall success rate of TUL. It appears that the incidence of infectious complications does not increase in patients undergoing TUL without antibiotic prophylaxis if they have negative pre-operative urine culture and antiseptic technique have been performed thorough the procedure.

    The selection of a prophylaxis regimen to prevent symptomatic pulmonary embolism and deep vein thrombosis is a balance between efficacy and safety. The latest American Academy of Orthopaedic Surgeons guideline recommended that either chemoprophylaxis or mechanical prophylaxis be used after total joint arthroplasty but did not recommend specific agents. However, the latest evidence-based American College of Chest Physicians guideline recommended a variety of chemoprophylaxis and mechanical agents for a minimum of 10 to 14 days after total joint arthroplasty. Risk stratification is the key to the selection of the appropriate prophylaxis regimen for the individual patient, but the optimal risk stratification protocol still needs to be developed.

    Full Text Available Objective : In hospital, deep vein thrombosis (DVT increases the morbidity and mortality in patients with acute medical illness. DVT prophylaxis is well known to be effective in preventing venous thromoembolism (VTE. However, its use remains suboptimal. The objective of this study was to evaluate the impact of quality improvement project on adherence with VTE prophylaxis guidelines and on the incidence of hospital-acquired VTEs in medical patients. Methods : The study was conducted at Saudi Aramco Medical Services Organization from June 2008 to August 2009. Quality improvement strategies included education of physicians, the development of a protocol, and weekly monitoring of compliance with the recommendations for VTE prophylaxis as included in the multidisciplinary rounds. A feedback was provided whenever a deviation from the protocol occurs. Results : During the study period, a total of 560 general internal medicine patients met the criteria for VTE prophylaxis. Of those, 513 (91% patients actually received the recommended VTE prophylaxis. The weekly compliance rate in the initial stage of the intervention was 63% (14 of 22 and increased to an overall rate of 100% (39 of 39 (P = 0.002. Hospital-acquired DVT rate was 0.8 per 1000 discharges in the preintervention period and 0.5 per 1000 discharges in the postintervention period, P = 0.51. However, there was a significant increase in the time-free period of the VTE and we had 11 months with no single DVT. Conclusion : In this study, the use of multiple interventions increased VTE prophylaxis compliance rate.

A monthly injection of palivizumab has been used for prophylaxis of serious RSV infections among high-risk children in 71 countries since 1998 and approval for use in the Russian Federation was obtained in February 2010. A recommendation for RSV prophylaxis in the Russian Federation would require knowledge of the prevalence and seasonality of RSV in that country.Methods: In a prospective, multicenter, epidemiological study of the prevalence, seasonality, and peak occurrence of RSV infection, children aged ≤2 years hospitalized for lower respiratory tract infections in three regions of the Russian Federation, from September 2008 through April 2009, were screened and tested for RSV using rapid immunochromatography of nasopharyngeal lavage. For subjects who were tested positive, hospitalization data were collected.Results: Of 519 children aged ≤2 years enrolled from September 11, 2008 through April 26, 2009, 197 tested positive for RSV (38.0%, 95% CI: 33.8, 42.3. The onset of the 2008–2009 RSV season in the Russian Federation occurred in late October 2008, similar to what is observed in other northern temperate zones. Peak activity occurred in early April 2009, when 62% of children enrolled tested positive for RSV.Conclusion: The prevalence

    Pre-exposure prophylaxis (PrEP) is an experimental approach to HIV prevention and consists of antiretroviral drugs to be taken before potential HIV exposure in order to reduce the risk of HIV infection and continued during periods of risk. An effective PrEP could provide an additional safety net to sexually active persons at risk, when combined with other prevention strategies. Women represent nearly 60% of adults infected with HIV and PrEP can be a female-controlled prevention method for women who are unable to negotiate condom use. Two antiretroviral nucleoside analog HIV-1 reverse transcriptase inhibitor drugs are currently under trial as PrEP drugs, namely tenofovirdisoproxilfumarate (TDF) alone and TDF in combination with emricitabine (FTC), to be taken as daily single dose oral drugs. There are 11 ongoing trials of ARV-based prevention in different at risk populations across the world. The iPrex trial showed that daily use of oral TDF/FTC by MSM resulted in 44% reduction in the incidence of HIV. This led to publication of interim guidance by CDC to use of PrEP by health providers for MSM. Few other trials are Bangkok Tenofovir Study, Partners PrEP Study, FEM-PrEP study, and VOICE (MTN-003) study. Future trials are being formulated for intermittent PrEP (iPrEP) where drugs are taken before and after sex, “stand-in dose” iPrEP, vaginal or rectal PrEP, etc. There are various issues/concerns with PrEP such as ADRs and resistance to TDF/FTC, adherence to drugs, acceptability, sexual disinhibition, use of PrEP as first line of defense for HIV without other prevention strategies, and cost. The PrEP has a potential to address unmet need in public health if delivered as a part of comprehensive toolkit of prevention services, including risk-reduction, correct and consistent use of condoms, and diagnosis and treatment of sexually transmitted infections.

    2003-07-01

    To the best of our knowledge, Stevens-Johnson syndrome (SJS) has not been reported previously as an adverse reaction to Malarone, which is a combination of atovaquone and proguanil hydrochloride used for antimalarial prophylaxis and therapy. We describe a 65-year-old patient who had SJS with typical clinical and histopathological findings associated with the use of Malarone prophylaxis for malaria. This report should alert physicians to this severe cutaneous reaction, and Malarone should be added to the list of drugs that can potentially cause SJS.

    Rsv1, a single dominant resistance locus in soybean, confers extreme resistance to the majority of Soybean mosaic virus (SMV) strains, but is susceptible to the G7 strain. In Rsv1-genotype soybean, G7 infection provokes a lethal systemic hypersensitive response (LSHR), a delayed host defence response. The Rsv1-mediated LSHR signalling pathway remains largely unknown. In this study, we employed a genome-wide investigation to gain an insight into the molecular interplay between SMV G7 and Rsv1-genotype soybean. Small RNA (sRNA), degradome and transcriptome sequencing analyses were used to identify differentially expressed genes (DEGs) and microRNAs (DEMs) in response to G7 infection. A number of DEGs, DEMs and microRNA targets, and the interaction network of DEMs and their target mRNAs responsive to G7 infection, were identified. Knock-down of one of the identified DEGs, the eukaryotic translation initiation factor 5A (eIF5A), diminished the LSHR and enhanced viral accumulation, suggesting the essential role of eIF5A in the G7-induced, Rsv1-mediated LSHR signalling pathway. This work provides an in-depth genome-wide analysis of high-throughput sequencing data, and identifies multiple genes and microRNA signatures that are associated with the Rsv1-mediated LSHR. © 2016 HER MAJESTY THE QUEEN IN RIGHT OF CANADA MOLECULAR PLANT PATHOLOGY © 2016 BSPP AND JOHN WILEY & SONS LTD.

    Rabies remains an important public health problem with more than 95% of all human rabies cases caused by exposure to rabid dogs in areas where effective, inexpensive vaccines are unavailable. Because of their ability to induce strong innate and adaptive immune responses capable of clearing the infection from the CNS after a single immunization, live-attenuated rabies virus (RV) vaccines could be particularly useful not only for the global eradication of canine rabies but also for late-stage rabies postexposure prophylaxis of humans. To overcome concerns regarding the safety of live-attenuated RV vaccines, we developed the highly attenuated triple RV G variant, SPBAANGAS-GAS-GAS. In contrast to most attenuated recombinant RVs generated thus far, SPBAANGAS-GAS-GAS is completely nonpathogenic after intracranial infection of mice that are either developmentally immunocompromised (e.g., 5-day-old mice) or have inherited deficits in immune function (e.g., antibody production or type I IFN signaling), as well as normal adult animals. In addition, SPBAANGAS-GAS-GAS induces immune mechanisms capable of containing a CNS infection with pathogenic RV, thereby preventing lethal rabies encephalopathy. The lack of pathogenicity together with excellent immunogenicity and the capacity to deliver immune effectors to CNS tissues makes SPBAANGAS-GAS-GAS a promising vaccine candidate for both the preexposure and postexposure prophylaxis of rabies.

    Kinetics of inactivation by the detergent spermicide benzalkonium chloride (BZK) of Chlamydia trachomatis and of a panel of DNA viruses [herpes simplex virus hominis type 2 (HSV-2), cytomegalovirus (CMV), adenovirus (ADV) and BK virus (BKV)] and RNA [respiratory syncytial virus (RSV) and enterovirus (ENV)] were established in accordance with a standardized in vitro protocol. After a 5 min incubation, inactivation of >95% of HSV-2 and CMV was obtained at a concentration of 0.0025% (w/v) (25 Ig/L); concentrations as low as 0.0005%, 0.0050% and 0.0125%, induced a 3.0 log10 reduction in infectivity of HSV-2 and CMV, RSV and ADV, respectively. After a 60 min incubation, concentrations of 0.0125% and 0.050% provided a 3.0 log10 reduction in infectivity of ENV and BKV, respectively. These features indicate that sensitivity to BZK was very high (HSV-2 and CMV) or high (RSV) for enveloped viruses, intermediate (ADV) or low (ENV and BKV) for non-enveloped viruses. Furthermore, BZK had marked antichlamydial activity, showing >99% killing after only a 1 min incubation at a concentration of 0.00125%. BZK demonstrates potent in vitro activity against the majority of microorganisms causing sexually transmitted infectious diseases, including those acting as major genital cofactors of human immunodeficiency virus transmission. These attributes qualify BZK as a particularly attractive candidate for microbicide development.

    2018-03-01

    Respiratory syncytial virus (RSV) is a common cause of respiratory infection that is highly prevalent in infants, particularly those with underlying medical conditions. Severe cases of RSV require hospitalisation as well as admission to intensive care and may even result in death. The objective of the study was to measure the net benefits that could arise from an immunisation programme of infants that may well eradicate RSV to a high degree and save the direct and indirect medical care costs from hospitalisation, morbidity and the gain from potential life-time earnings by reducing the probability of mortality. In this context, the majority of existing empirical investigations are based on data from clinical trials, and where relevant facts are not available, a series of strong assumptions is derived from the published literature, whereas in this study, for the first time, the hospital episode statistics database is used to calculate the cost-benefit ratios. The methodology of the analysis adopts a cost-benefit approach to assess the impact of the immunisation and whether it is beneficial to society. The underlying assumptions of the basic model are assessed by adopting a sensitivity analysis. The results show that a number of categories are cost-effective with the use of the passive drug, which means benefits by raising the life expectancy and quality as well as reducing the resource burden on society.

    Full Text Available Background: The aim of this study was to prospectively compare single-dose intravenous antibiotic prophylaxis vs. no prophylaxis before minor cystoscopic procedures, including punch biopsy and transurethral resection (TUR of small bladder tumors. Materials and Methods: A total of 200 patients with a mean age of 47.3 years old (range: 19-84 years old with initial negative urine cultures were recruited. All patients underwent a diagnostic cystoscopy. Patients were then randomized into 2 groups: o0 ne group that did not receive antibiotics (100 patients and the other group that received antibiotic treatment (100 patients with a single intravenous dose of cefoperazone. All patients had urine analysis and urine cultures on the second day after the operation. Additionally, clinical parameters including fever and dysuria were recorded. In 15% of the patients, incidental additional interventions such as punch biopsy or TUR of a small bladder tumor that were similarly distributed in both groups were performed. Results: In 1 patient from the antibiotic group and 2 patients from the no prophylaxis group, the urine cultures after cystoscopy were positive. No statistically significant difference was observed between these groups based on the microbiological and clinical parameters. Conclusion: The current study provides evidence that no antibiotic prophylaxis is required before diagnostic cystoscopy in patients without bacteriuria. But, the absolute risk of infection was small, suggesting that a much larger study is required.

  18. Rationale for a randomized controlled trial comparing two prophylaxis regimens in adults with severe hemophilia A: the Hemophilia Adult Prophylaxis Trial

    Science.gov (United States)

    Ragni, Margaret V

    2011-01-01

    A major goal of comprehensive hemophilia care is to prevent occurrence of bleeds by prophylaxis or regular preventive factor, one or more times weekly. Although prophylaxis is effective in reducing bleeding and joint damage in children, whether it is necessary to continue into adulthood is not known. The purpose of this article is to describe a Phase III randomized controlled trial to evaluate prophylaxis comparing two dose regimens in adults with severe hemophilia A. I hypothesize that adults with mature cartilage and joints are less susceptible to joint bleeds and joint damage, and that once-weekly recombinant factor VIII prophylaxis, with up to two rescue doses per week, is as effective as thrice-weekly prophylaxis in reducing bleeding frequency, but less costly and more acceptable, with higher quality of life. The ultimate goal of this project is to determine whether once-weekly prophylaxis is any worse than thrice-weekly prophylaxis in reducing joint bleeding frequency, while potentially utilizing less factor, at lower cost, leading to a better quality of life. This is an innovative concept, as it challenges the current paradigm of thrice-weekly prophylaxis in adults, which is based on dosing in children. Furthermore, this trial will assess interdose thrombin generation, a novel tissue factor-based assay of hemostasis, to determine if individualized thrombin generation can predict more individualized prophylaxis dosing, which would be practice changing.

    2017-09-01

    Full Text Available Despite the global stabilization of the number of new HIV infections in recent years, there has been an increase in new infections among men who have sex with men. This fact indicates the lack of effectiveness of the measures and prevention campaigns established so far for this group. It is therefore necessary to implement alternative preventive measures for them. Pre-exposure pharmacological prophylaxis (PrEP is one of the best evaluated options and has had high protection rates in both clinical and real-life trials. The strategy has also shown an adequate profile in terms of safety, tolerance, adverse effects and cost-effectiveness in the studies carried out to assess this important topic.

    Keenan, James R; Veitz-Keenan, Analia

    2015-06-01

    Electronic searches without time or language restrictions were performed in PubMed, Web of Science and the Cochrane Oral Health Group trials Register. A vast manual search was done in many dental implant-related journals. Reference lists were scanned for possible additional studies. Ongoing clinical trials were also searched. Titles and abstracts of the reports identified were read independently by the three authors. Disagreements were resolved by discussion. Rejected studies were recorded with the reasons for exclusion. The inclusion criteria included clinical human studies, either randomised or not, comparing the implant failure/survival rates in any group of patients receiving antibiotic prophylaxis versus not receiving antibiotics prior to implant placement. Case reports and non-human studies were excluded. Implant failure was considered as complete loss of the implant. Data were extracted by the authors. Study risk of bias was assessed. Implant failure and post-operative infection were the outcomes measured, both dichotomous outcomes. Results were expressed using fixed or a random effect model depending on the heterogeneity calculated using an I(2) statistical test. The estimate of relative effect was expressed in risk ratio (RR) with 95% confidence interval. Number needed to treat (NNT) was calculated and sensitivity analysis was performed to detect differences among the studies considered to have high a risk of bias. Fourteen trials were included in the review and evaluated a total of 14,872 implants. Of the fourteen studies included in the review eight were randomised clinical trials, four were controlled clinical trials and two were retrospective studies. Seven studies had both patients and operators/outcome assessors blinded to the tested intervention. Nine studies had short follow-ups; six of them with a follow-up of four months, one of five months and two of six months.The antibiotic regimen was variable: seven studies did not use post-op antibiotics in

  1. Regulation of mTORC1 Signaling by Src Kinase Activity Is Akt1-Independent in RSV-Transformed Cells

    2008-02-01

    Full Text Available Increased activity of the Src tyrosine protein kinase that has been observed in a large number of human malignancies appears to be a promising target for drug therapy. In the present study, a critical role of the Src activity in the deregulation of mTOR signaling pathway in Rous sarcoma virus (RSV-transformed hamster fibroblasts, H19 cells, was shown using these cells treated with the Src-specific inhibitor, SU6656, and clones of fibroblasts expressing either the active Src or the dominant-negative Src kinase-dead mutant. Disruption of the Src kinase activity results in substantial reduction of the phosphorylation and activity of the Akt/protein kinase B (PKB, phosphorylation of tuberin (TSC2, mammalian target of rapamycin (mTOR, S6K1, ribosomal protein S6, and eukaryotic initiation factor 4E-binding protein 4E-BP1. The ectopic, active Akt1 that was expressed in Src-deficient cells significantly enhanced phosphorylation of TSC2 in these cells, but it failed to activate the inhibited components of the mTOR pathway that are downstream of TSC2. The data indicate that the Src kinase activity is essential for the activity of mTOR-dependent signaling pathway and suggest that mTOR targets may be controlled by Src independently of Akt1/TSC2 cascade in cells expressing hyperactive Src protein. These observations might have an implication in drug resistance to mTOR inhibitor-based cancer therapy in certain cell types.

    A prospective multicentre study was conducted to assess major aspects of surgical prophylaxis and to determine whether inappropriate antimicrobial prophylaxis was a factor associated (risk or protective factor) with surgical site infection (SSI). Surgical prophylaxis practices were assessed by analysing four variables: indication, antimicrobial agent, timing and duration. Univariate and multivariate analyses were carried out to identify predictors of SSI among patient-specific, operation-specific and antimicrobial prophylaxis-specific factors. The frequency of SSI was 2.7% (13 SSI in 474 observations). Total compliance of the prescription with guidelines was observed in 41.1% of cases (195 prescriptions). Of the 139 patients who received an inappropriate drug, 126 (90.6%) received a drug with a broader spectrum than the recommended drug. Prophylaxis was prolonged in 71 (87.7%) of the 81 patients who received prophylaxis for inappropriate lengths of time and 43 (61.4%) of the 70 patients who did not receive prophylaxis at the optimal moment were treated too late. Multivariate analysis clearly demonstrated that SSI was associated with multiple procedures (relative risk 8.5), short duration of prophylaxis (relative risk 12.7) and long-term therapy with antimicrobial agents during the previous year (relative risk 8.8). The ecological risk of the emergence of resistance associated with the frequent use of broad-spectrum antibiotics and prophylaxis for longer periods was not offset by individual benefit to the patients who received inappropriate prophylaxis.

    Bacterial infection following cancer chemotherapy-induced neutropenia is a serious cause of morbidity and mortality in human and veterinary patients. Antimicrobial prophylaxis is controversial in the human oncology field, as any decreased incidence in bacterial infections is countered by patient adverse effects and increased antimicrobial resistance. Comprehensive guidelines exist to aid human oncologists in prescribing antimicrobial prophylaxis but similar recommendations are not available in veterinary literature. As the veterinarian's role in antimicrobial stewardship is increasingly emphasized, it is vital that veterinary oncologists implement appropriate antimicrobial use. By considering the available human and veterinary literature we present an overview of current clinical practices and are able to suggest recommendations for prophylactic antimicrobial use in veterinary cancer chemotherapy patients. © 2018 The Authors.

    2011-08-01

    Full Text Available Spontaneous intracerebral haemorrhage (SIH represents a severe clinical event that is associated with high rates of mortality and morbidity. Only a minority of SIH patients receive surgical treatment, whereas the majority are treated conservatively. Venous thromboembolism (VTE is one of the most common complications in SIH patients and a potential cause of death. Because of the lack of adequate evidences from the literature, the risk to benefit ratio of pharmacologic prophylaxis of VTE, represented on the one hand by hematoma enlargement and/or rebleeding and on the other hand by an expected reduction of the risk of VTE, remains controversial. Mechanical prophylaxis is a potentially safer alternative, but the efficacy of this approach is uncertain. In the absence of specific clinical guidelines containing clear-cut recommendations, physicians have insufficient tools to assist their therapeutic decisions.

Post-exposure prophylaxis (PEP is the use of short-term antiretroviral therapy (ART to reduce the risk of acquisition of HIV infection following exposure. Current guidelines recommend a 28-day course of ART within 36–72 hours of exposure to HIV. As long as individuals continue to be exposed to HIV there will be a role for PEP in the foreseeable future. Nonoccupational PEP, the vast majority of which is for sexual exposure (PEPSE, has a significant role to play in HIV prevention efforts. Awareness of PEP and its availability for both clinicians and those who are eligible to receive it are crucial to ensure that PEP is used to its full potential in any HIV prevention strategy. In this review, we provide current evidence for the use of PEPSE, assessment of the risk of HIV transmission, indications for PEP, drug regimens, and management of patients started on PEP. We summarize national and international guidelines for the use of PEPSE. We explore the place of PEP within the wider strategy of reducing HIV incidence rates in the era of treatment as prevention and pre-exposure prophylaxis. We also consider the implications of recent data from interventional and observational studies demonstrating significant reductions in the risk of HIV transmission within a serodiscordant relationship if the HIV-positive partner is taking effective ART upon PEP guidelines.

    BACKGROUND: Cytomegalovirus (CMV) is the most common opportunistic infection after solid-organ transplantation, increasing morbidity and mortality. Three months of oral valganciclovir have been shown to provide effective prophylaxis. Late-onset CMV disease, occurring after the discontinuation of prophylaxis, is now increasingly recognised. AIMS: To investigate the incidence and the time of detection of CMV infections in liver transplant recipients who received CMV prophylaxis. METHODS: Retrospective review of 64 high- and moderate-risk patients with 1 year of follow-up. RESULTS: The incidence of CMV infection was 12.5%, with 4.7% disease. All cases of symptomatic CMV disease were of late-onset. CONCLUSIONS: The incidence of CMV infections in this study was low compared with literature reports; however, the late-onset disease is an emerging problem. Detection of late-onset disease may be delayed because of less frequent clinic follow-up visits. Increased regular laboratory monitoring may allow earlier detection at the asymptomatic infection stage.

  15. WHO's new recommendations about iodine prophylaxis at nuclear catastrophes

    International Nuclear Information System (INIS)

    1999-01-01

    WHO has prepared new advice about using stable iodine as protection against emission of radioactive iodine from nuclear catastrophes. The experiences from Chernobyl show that the risk for thyroid gland cancer after emission of radio-iodine is significant. The risk of serious side effects of stable iodine as single dose is stated to be minimal. Stable iodine is a safe, effective remedy for protecting the thyroid gland against radioactive iodine. It is recommended to adjust different criteria for iodine prophylaxis for new-born, children, young people and adults older than 40 years. For children of the age up to 18 years iodine prophylaxis should be considered at 10 mGy thyroid gland doses, and for young adults at 100 mGy. For adults of 40 years or more the cancer risk of radioactive iodine is very low and iodine prophylaxis is unnecessary provided that the expected does not exceed 5 Gy. The new information about risk and advantage must be considered in planning for distribution and storage of stable iodine. WHO also commends that everybody has the possibility to buy it in a pharmacy. (EHS)

    1979-01-01

    Prophylaxis against meningosis leukemia (ML) via intrathecal radioactive colloid gold injection was carried out for a period of three years (January 1974 - September 1976) in 21 children with acute lymphoblast leukemia (ALL). The analysis of those patients after one relatively long period of observation (28 months after the last case) reveals that ML developed as a primary isolated manifestation of a recurrence in three children, i.e. in 14.2 per cent versus 68 per cent in the control group without prophylaxis. In another child ML development is in parallel with bone marrow recurrence. The reduction of ML incidence is accompanied with a prolongation of the first remission (in 24 per cent over 2 years and 6 months) and a lengthening of survival for 50 per cent of the patients (62 per cent of the treated patients are alive two years and 4 months during the period of observation). The advantages of the prophylaxis with radioactive colloid gold is emphasized in comparison with the other prophylactic programmes.

    2010-10-01

    A systematic review was conducted to evaluate evidence regarding xylitol, a sugar alcohol, as a prophylaxis for acute otitis media (AOM) in children. The authors searched PubMed and other databases to identify evidence. Criteria for included studies were: appear in English-language, peer-reviewed journals; at least quasi-experimental designs; use xylitol; and present outcome data. The authors completed evaluation forms for the included studies at all phases of the review. The authors reviewed 1479 titles and excluded 1435. Abstracts and full texts were reviewed for the remaining 44; four randomized controlled trials met inclusion criteria. Xylitol was a generally well accepted prophylaxis for AOM with few side effects when administered via chewing gum or syrup at 10 g/day given five times daily. Meta-analysis revealed significant treatment effects (Risk ratio = 0.68; 95% confidence interval = 0.57 to 0.83). Xylitol can be a prophylaxis for AOM, but warrants further study, especially of vehicles other than chewing gum for young children, and information is needed regarding cost, duration of administration required, and expected long-term effects.

    Full Text Available Fausto de LallaLibero Docente of Infectious Diseases, University of Milano, Milano, ItalyAbstract: Despite improvement in infection control measures and surgical practice, surgical site infections (SSIs remain a major cause of morbidity and mortality. In colorectal surgery, perioperative administration of a suitable antimicrobial regimen that covers both anaerobic and aerobic bacteria is universally accepted. In a prospective, double-blind, randomized study ertapenem was recently found to be more effective than cefotetan, a parenteral cephalosporin so broadly used as to be considered as gold standard in the prevention of SSIs following colorectal surgery. In this adequate and well controlled study, the superiority of ertapenem over cefotetan was clearly demonstrated from the clinical and bacteriological points of view. However, data that directly compares ertapenem with other antimicrobial regimen effective in preventing SSIs following colorectal surgery are lacking; furthermore, the possible risk of promotion of carbapenem resistance associated with widespread use of ertapenem prophylaxis as well as the ertapenem effects on the intestinal gut flora are of concern. Further comparative studies of ertapenem versus other widely used prophylactic regimens for colorectal surgery in patients submitted to mechanical bowel preparation versus no preparation as well as further research on adverse events of antibiotic prophylaxis, including emergence of resistance and Clostridium difficile infection, seem warranted.Keywords: colorectal surgery, surgical prophylaxis, ertapenem

    HIV pre-exposure prophylaxis has been proven to be an effective tool in HIV prevention. However, numerous barriers still exist in pre-exposure prophylaxis implementation. The framework of Intervention Mapping was used from August 2016 to October 2017 to describe the process of adoption, implementation, and maintenance of an HIV prevention program from 2012 through 2017 in Houston, Texas, that is nested within a county health system HIV clinic. Using the tasks outlined in the Intervention Mapping framework, potential program implementers were identified, outcomes and performance objectives established, matrices of change objectives created, and methods and practical applications formed. Results include the formation of three matrices that document program outcomes, change agents involved in the process, and the determinants needed to facilitate program adoption, implementation, and maintenance. Key features that facilitated successful program adoption and implementation were obtaining leadership buy-in, leveraging existing resources, systematic evaluation of operations, ongoing education for both clinical and nonclinical staff, and attention to emergent issues during launch. The utilization of Intervention Mapping to delineate the program planning steps can provide a model for pre-exposure prophylaxis implementation in other settings. Copyright © 2018.

    Virus of piggy grippe is a virus of type A, which has greatly changed in it's antigenic structure. As a result, has appeared a new variant of germ (syb-type), in relation to which vaccines, used for period 2008-2009, are unsuccessful. Virus represents a real risk for life and health of millions of people. Experts of World Health Organization are sure, that eruption can lead to a global expansion of virus. To the group of high risk refer: children younger then 5 years old, full-growns of 50 years old and older, children and teen-agers (from 6 months to 18 years), treated for a long time by aspirin, gravidas, full-growns with several chronic diseases, persons in nursing homes, hospices, requiring a long-termed hipurgia, compulsory-duty servicemen. Latent period is from 1 to 7 days (2-3 days on the average). Accountancy of clinical data: acute beginning, hyperpyretic fever, predominance of damages of upper respiratory tracts.

  2. Intermittent diazepam prophylaxis in febrile convulsions. Pros and cons.

    Knudsen, F U

    1991-01-01

    Major cohort studies document that the long-term prognosis for most children with febrile convulsions (FC) is excellent. The 2 main treatment alternatives so far have been long-term prophylaxis with phenobarbital or valproate or no prophylaxis at all. Phenobarbital at times of fever is ineffective and obsolete. Consensus has emerged that long-term prophylaxis with antiepileptic drugs is rarely justified in FC considering the side effects and the favourable prognosis. No treatment at all does not appear quite satisfactory either, as FC have a high recurrence rate, disrupt family life and may have emotional consequences for the family. Moreover, all FC children face a risk, although admittedly low, of subsequent long-lasting potentially central nervous system (CNS)-damaging seizures. However, 2 further options exist: treatment with rapid-acting benzodiazepines solely at times of greatest risk, i.e., at high fever or at renewed seizures. Several clinical trials have confirmed that intermittent diazepam prophylaxis by way of a few doses of the drug per year provides effective seizure control and reduces the recurrence rate by one half or two thirds. The treatment is feasible and cheap, well tolerated by the child and well accepted by the parents. Compliance problems are common and only partly abatable. Trivial side effects are frequent. Transient respiratory apnoea does occur, but 15 years' experience substantiates that serious side effects are remarkably rare. Acute anticonvulsant treatment with rectal diazepam in solution given by the parents to stop ongoing seizures and to prevent immediate recurrences is an attractive alternative. It is feasible, is probably effective and minimizes the use of drugs, but compliance problems are common and protracted seizures are not always controlled. The subsequent management should include a risk profile approach considering a combination of risk factors for new FC rather than a single factor. By means of a risk index, based on

    Cancer prophylaxis seems nowadays to be the more and more powerful tool in fight with these serious diseases. The aim of this work is to find out opinions of students of nursing extension studies on contemporary cancer prophylaxis. The question about possibilities of practical efforts for prophylaxis and early detection of cancer was directed to 160 students of four consecutive years (2002-2006), at the end of the fourth year of lasting five and a half years extension nursing studies, during ending exam on subject: oncological nursing. There were 154 women and 6 men, predominantly at their third decade of life, with nursing experience approximately more than 5 years. Out of 160 asked students, 131 of them firstly indicated necessity of breast cancer prophylaxis, 117 mentioned lung cancer, 113 cervix cancer, 95 colorectal cancer, 33 prostate cancer. In families with cancer problems, more frequent control investigations (23 answers), and genetic tests (16) were called for. Patients should be qualified to appropriate risk groups (13) and controlled more frequently there (24). Apart from necessary wide education in media (126) personal contact with patient to discuss his or her personal problems relating to cancer is needed (91). If atypical symptoms are self-detected by patients it should alert them to not neglect and contact family physician (33). Healthy diet (62) containing fresh vegetables and fruits (73), high fibre diet (42) with less animal fat (38) and less red meat (30), containing no preservative agents (45) is recommended. Increased physical activity (84) to cease or reduce smoking (102), and alcohol intake (55), limited exposition to ultraviolet rays (49), and systematic controls of breast (105), uterus cervix (88), lungs (77), colon (55) and prostate (28) are proposed. The pollution of environment by combustion gases and smokes (34) not excluding risk factors of medical workplace (29) are mentioned as cancerogenic factors. In the time of increasing

  4. Long-term, low-dose prophylaxis against urinary tract infections in young children.

    2015-03-01

    Urinary tract infection (UTI) affects about 2 % of boys and 8 % of girls during the first 6 years of life with Escherichia coli as the predominant pathogen. Symptomatic UTI causes discomfort and distress, and carries a risk of inducing renal damage. The strong correlation between febrile UTI, dilating vesicoureteral reflux (VUR), and renal scarring led to the introduction of antibiotic prophylaxis for children with VUR to reduce the rate of UTI recurrence. It became common practice to use prophylaxis for children with VUR and other urinary tract abnormalities. This policy has been challenged because of a lack of scientific support. Now, randomized controlled studies are available that compare prophylaxis to no treatment or placebo. They show that children with normal urinary tracts or non-dilating VUR do not benefit from prophylaxis. Dilating VUR may still be an indication for prophylaxis in young children. After the first year of life, boys have very few recurrences and do not benefit from prophylaxis. Girls with dilating VUR, on the other hand, are more prone to recurrences and benefit from prophylaxis. There has been a decline in the use of prophylaxis due to questioning of its efficacy, increasing bacterial resistance, and a propensity to low adherence to medication. Alternative measures to reduce UTI recurrences should be emphasized. However, in selected patients carefully followed, prophylaxis can protect from recurrent UTI and long-term sequelae. 1. There is a strong correlation between UTI, VUR, and renal scarring. 2. Children with normal urinary tracts or non-dilating VUR do not benefit from prophylaxis. 3. Young children, mainly girls, with dilating VUR are at risk of recurrent UTI and acquired renal scarring and seem to gain from antibiotic prophylaxis. 4. Increasing bacterial resistance and low adherence with prescribed medication is a major obstacle to successful antibiotic prophylaxis.

    Bacterial infections occurring during labour, childbirth, and the puerperium may be associated with considerable maternal and perinatal morbidity and mortality. Antibiotic prophylaxis might reduce wound infection incidence after an episiotomy, particularly in situations associated with a higher risk of postpartum perineal infection, such as midline episiotomy, extension of the incision, or in settings where the baseline risk of infection after vaginal birth is high. However, available evidence is unclear concerning the role of prophylactic antibiotics in preventing infections after an episiotomy. To assess whether routine antibiotic prophylaxis before or immediately after incision or repair of episiotomy for women with an uncomplicated vaginal birth, compared with either placebo or no antibiotic prophylaxis, prevents maternal infectious morbidities and improves outcomes. We searched the Cochrane Pregnancy and Childbirth's Trials Register, LILACS, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform (ICTRP) on 24 July 2017, and screened reference lists of retrieved studies. We considered randomised controlled trials, quasi-randomised trials, and cluster-randomised trials that compared the use of routine antibiotic prophylaxis for incision or repair of an episiotomy for women with otherwise normal vaginal births, compared with either placebo or no antibiotic prophylaxis. Two review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy. We only found one quasi-randomised trial that met the inclusion criteria and was included in the analysis, therefore, we did not perform a meta-analysis. We included one quasi-RCT (with data from 73 women) in the review. The trial, which was conducted in a public hospital in Brazil, compared oral chloramphenicol 500 mg four times daily for 72 hours after episiotomy repair (N = 34) and no treatment (N = 39). We assessed most of the domains at high

    Although pre-exposure prophylaxis (PrEP)-the use of antiretroviral drugs by non-infected people to prevent the acquisition of HIV-is a promising preventive option, important public health questions remain. Daily oral emtricitabine (FTC)-tenofovir disoproxil fumarate (TDF) is highly efficacious in preventing the acquisition of HIV in people at risk as a result of a range of different types of sexual exposure. There is good evidence of efficacy in women and men, and when men who have sex with men use event based dosing. Studies have been conducted in several countries and epidemics. Because adherence to this treatment varies greatly there are questions about its public health benefit. Oral FTC-TDF is extremely safe, with minimal impact on kidney, bone, or pregnancy outcomes, and there is no evidence that its effectiveness has been reduced by risk compensation during open label and programmatic follow-up. It is too early to assess the impact of this treatment on the incidence of sexually transmitted infections (STIs) at a population level. Many challenges remain. Access to pre-exposure prophylaxis is limited and disparities exist, including those governed by race and sex. Different pricing and access models need to be explored to avoid further widening inequalities. The optimal combination prevention program needs to be defined, and this will depend on local epidemiology, service provision, and cost effectiveness. This review updates the evidence base for pre-exposure prophylaxis regarding its effectiveness, safety, and risk compensation. Published by the BMJ Publishing Group Limited.

    Patients who undergo orthopaedic oncologic surgical procedures are at increased risk of developing a venous thromboembolism (VTE). Guidelines from surgical societies are shifting to include aspirin as a postoperative VTE prophylactic agent. The purpose of this study was to review our experience using aspirin as postoperative VTE prophylaxis for orthopaedic oncologic surgical procedures. This study was a retrospective review of patients diagnosed with a primary malignant soft-tissue or bone tumor or metastatic carcinoma. Demographic information, histopathologic diagnosis, VTE history, surgical procedure, and VTE prophylaxis were analyzed. VTE rates in the overall and prophylactic-specific cohorts were recorded and compared. A total of 142 distinct surgical procedures in 130 patients were included. VTE prophylaxis with aspirin was used after 103 procedures, and non-aspirin prophylaxis was used after 39. In 33 cases, imaging was used to investigate for VTE because of clinical signs and symptoms. VTE developed after 7 (4.9%) of the 142 procedures. There were 6 deep venous thromboses (DVTs) and 1 pulmonary embolism, and 2 of the VTEs presented in patients with a VTE history. VTE developed in 2.9% (3) of the 103 aspirin cases and 10.3% (4) of the 39 non-aspirin cases. No patient in the aspirin group who had been diagnosed with metastatic carcinoma, malignant soft-tissue sarcoma, lymphoma, or multiple myeloma developed a VTE. Risk factors for VTE development included diabetes mellitus (odds ratio [OR] = 10.40, 95% confidence interval [CI] = 1.61 to 67.30), a history of VTE (OR = 7.26, 95% CI = 1.19 to 44.25), postoperative transfusion (OR = 34.50, 95% CI = 3.94 to 302.01), and estimated blood losses of 250 mL (OR = 1.50, 95% CI = 1.11 to 2.03), 500 mL (OR = 2.26, 95% CI = 1.23 to 4.13), and 1,000 mL (OR = 5.10, 95% CI = 1.52 to 17.04). Aspirin may be a suitable and effective option for VTE chemoprophylaxis in patients treated with orthopaedic oncologic surgery, especially

    In children with congenital glaucoma the functional long-term result is often disappointing even if the intraocular pressure is well controlled. The reason for this discrepancy is attributed to amblyogenic factors responsible for interfering with normal visual development. These amblyogenic factors are corneal edema, irregular astigmatism and non-corrected ametropia as monocular causes. Binocular causes are anisometropia-induced suppression and strabismus. Full ametropic correction and a very early prophylaxis and treatment of amblyopia with a close follow-up are mandatory to reduce amblyogenic visual impairment in children with congenital glaucoma.

    The major development in DVT prophylaxis in recent years has been the introduction of low molecular weight heparins. Their main improvement compared with unfractionated heparin is in the convenience of a once daily dosage, but they have not yet convincingly been shown to be more effective or safer. A-V impulse boots may have an impact on knee and hip surgery but still face problems with patient acceptability. Probably the best way to ensure that more DVT are prevented is by clinicians maintaining a high level of awareness of the risk, and developing, and adhering to, local guidelines.

    Antibiotic prophylaxis is the most suitable tool for preventing surgical wound infection. This study evaluated adequacy of antibiotic prophylaxis in surgery for knee arthroplasty and its effect on surgical site infection. Prospective cohort study. We assessed the degree of adequacy of antibiotic prophylaxis, the causes of non-adequacy, and the effect of non-adequacy on surgical site infection. Incidence of surgical site infection was studied after a maximum incubation period of a year. To assess the effect of prophylaxis non-adequacy on surgical site infection we used the relative risk adjusted with the aid of a logistic regression model. The study covered a total of 1749 patients. Antibiotic prophylaxis was indicated in all patients and administered in 99.8% of cases, with an overall protocol adequacy of 77.6%. The principal cause of non-compliance was the duration of prescription of the antibiotics (46.5%). Cumulative incidence of surgical site infection was 1.43%. No relationship was found between prophylaxis adequacy and surgical infection (RR=1.15; 95% CI: .31-2.99) (P>.05). Surveillance and infection control programs enable risk factors of infection and improvement measures to be assessed. Monitoring infection rates enables us to reduce their incidence. Adequacy of antibiotic prophylaxis was high but could be improved. We did not find a relationship between prophylaxis adequacy and surgical site infection rate. Copyright © 2017 SECOT.

    2016-08-01

    In 2007, the American Heart Association modified the infective endocarditis prophylaxis guidelines by limiting the use of antibiotics in patients with cardiac conditions associated with the highest risk of adverse outcomes after infective endocarditis. Our objective was to evaluate current practice for infective endocarditis prophylaxis among paediatric cardiologists. A web-based survey focussing on current practice, describing the use of antibiotics for infective endocarditis prophylaxis in various congenital and acquired heart diseases, was distributed via e-mail to paediatric cardiologists. The survey was kept anonymous and was distributed twice. Data from 253 participants were analysed. Most paediatric cardiologists discontinued infective endocarditis prophylaxis in patients with simple lesions such as small ventricular septal defect, patent ductus arteriosus, and bicuspid aortic valve without stenosis or regurgitation; however, significant disagreement persists in prescribing infective endocarditis prophylaxis in certain conditions such as rheumatic heart disease, Fontan palliation without fenestration, and the Ross procedure. Use of antibiotic prophylaxis in certain selected conditions for which infective endocarditis prophylaxis has been indicated as per the current guidelines varies from 44 to 83%. Only 44% follow the current guidelines exclusively, and 34% regularly discuss the importance of oral hygiene with their patients at risk for infective endocarditis. Significant heterogeneity still persists in recommending infective endocarditis prophylaxis for several cardiac lesions among paediatric cardiologists. More than half of the participants (56%) do not follow the current guidelines exclusively in their practice. Counselling for optimal oral health in patients at risk for infective endocarditis needs to be optimised in the current practice.

    New tools are needed to bring down ongoing high HIV incidence. This review aims to evaluate the place of one of these new tools (pre-exposure prophylaxis) in a comprehensive prevention strategy. Several trials have demonstrated the safety and the efficacy of pre-exposure prophylaxis in HIV prevention. Two large trials have, however, failed to show such efficacy. This was likely due to poor adherence in these trials. New forms of long-acting pre-exposure prophylaxis currently in trials may deal with these problems of low adherence. Pre-exposure prophylaxis has been demonstrated to be cost-effective within certain settings. The introduction of pre-exposure prophylaxis into prevention programs needs to be carefully thought through. For example, pre-exposure prophylaxis-induced risk compensation, at both an individual and population level, could undermine other aspects of a comprehensive HIV prevention program. In conclusion, pre-exposure prophylaxis could be a useful additional tool for the prevention of HIV in specific high-risk groups. It should be implemented in a way that deals with issues such as ensuring high adherence and ensuring that pre-exposure prophylaxis does not detract from, but complements, other more fundamental elements of HIV prevention programs.

    The spread of drug-resistant malaria and appreciation of side effects associated with existing antimalarial drugs emphasize the need for new drugs to prevent malaria. The combination of atovaquone and proguanil hydrochloride was previously shown to be safe and highly effective for treatment of malaria, including multi-drug-resistant Plasmodium falciparum. We reviewed results of clinical trials that evaluated either a fixed-dose combination of atovaquone and proguanil hydrochloride for malaria prophylaxis or atovaquone alone for causal prophylactic activity against P. falciparum. In three placebo-controlled trials, 331 subjects received 250 mg atovaquone and 100 mg proguanil hydrochloride (or an equivalent dose based on body weight in children) once daily for 10 to 12 weeks. The overall efficacy for preventing parasitemia was 98%. Among 175 nonimmune volunteers taking the same dose of atovaquone/proguanil once daily for 10 weeks while temporarily residing in a malaria-endemic area, malaria developed in one patient who was noncompliant with therapy. Results of volunteer challenge studies indicate that both atovaquone and proguanil have causal prophylactic activity directed against the liver stages of P. falciparum. Adverse events occurred with similar or lower frequencies in subjects treated with atovaquone/proguanil compared to placebo. Less than 1% of patients discontinued from these studies due to a treatment-related adverse event. A fixed-dose combination of atovaquone and proguanil hydrocloride is a promising new alternative for malaria prophylaxis.

  6. TETANUS—Prophylaxis and Treatment of the Disease

    Ross, Donald E.; Kraut, J. J.

    1959-01-01

    Cleansing and debridement is paramount in dealing with tetanus-prone wounds (severe crushing injuries, piercing wounds, blisters and burns are outstanding examples, particularly if contaminated with dirt, grass or other debris). Prophylaxis then is relatively easy in persons who have been actively immunized by toxoid injections. For them, a “booster” injection is indicated. Use of antitoxin, however, is hazardous, whether for prophylaxis or for treatment of the disease. Since it may in itself cause severe disease, including anaphylactic reaction and serum sickness, decision to use it must be weighed against the possibility of the development of tetanus in each case. To prepare for use of it, careful history should be taken, with particular reference to sensitivity to horse dander. Dermal tests, and perhaps ophthalmic tests, for sensitivity to the serum should be carried out. Even the tests may be hazardous and precautions should be taken accordingly. If it is decided that the use of antitoxin is necessary even though the patient is sensitive to the material, desensitization must be carried out promptly, with adequate preparation for severe reaction. There is experimental evidence that antibiotics of the tetracycline group, given soon after injury, may have prophylactic effect against tetanus. PMID:13651954

  7. Non-Antibiotic Prophylaxis for Urinary Tract Infections

    2016-04-01

    Full Text Available Increasing antimicrobial resistance has stimulated interest in non-antibiotic prophylaxis of recurrent urinary tract infections (UTIs. Well-known steps in the pathogenesis of UTIs are urogenital colonization and adherence of uropathogens to uroepithelial cell receptors. To prevent colonization in postmenopausal women, vaginal, but not oral, estrogens have been shown to restore the vagina lactobacilli flora, reduce vaginal colonization with Enterobacteriaceae, and reduce the number of UTIs compared to placebo. Different lactobacilli strains show different results in the prevention of recurrent UTIs. Intravaginal suppositories with Lactobacillus crispatus in premenopausal women and oral capsules with Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 in postmenopausal women are promising. Ascorbic acid (vitamin C cannot be recommended for the prevention of UTIs. Cranberries are thought to contain proanthocyanidins that can inhibit adherence of P-fimbriated E. coli to the uroepithelial cell receptors. Cranberry products decreased UTI recurrences about 30%–40% in premenopausal women with recurrent UTIs, but are less effective than low-dose antimicrobial prophylaxis. However, the optimal dose of cranberry product has still to be determined. Initially OM-89, a vaccine with 18 heat-killed E. coli extracts, seemed promising, but this was not confirmed in a recently randomized trial.

    To determine the prevalence of transient bacteraemia after CT colonography (CTC). Blood cultures were obtained at 5, 10 and 15 min after CTC from 100 consecutive consenting patients. Blood samples were cultured in both aerobic and anaerobic media and positive blood culture samples were analysed by a microbiologist. Blood culture samples were positive for growth in sixteen patients. All positive blood culture samples were confirmed skin contaminants. There were no cases of significant bacteraemia. The estimated significant bacteraemia rate as a result of CTC is 0-3.7%, based on 95% confidence intervals around extreme results using Wilson's score method. American Heart Association and National Institute for Clinical Excellence guidelines advise that antibiotic prophylaxis before lower gastrointestinal endoscopy is not indicated in patients with at risk cardiac lesions (ARCL) as the risk of a transient bacteraemia leading to infective endocarditis is low. These data show that the prevalence of transient bacteraemia after CTC is also low. It follows that patients with ARCL do not require antibiotic prophylaxis before CTC. (orig.)

    Malaria is still a serious public health problem in the world and control remains a major priority for the approximately 25.000 French troops deployed, mostly on permanent assignment, in malaria transmission regions. Epidemiological surveillance of malaria provides data necessary to assess morbidity, monitor changing patterns of Plasmodium falciparum drug-sensitivity, and evaluate the efficacy of malaria control measures. About 540 cases were observed in 1999 for an incidence of 4.1 p. 100 men. year. Since 1991, strong emphasis has been placed on prophylaxis. In addition to vector control measures and individual protection against mosquito bites (impregnated bednets, protective clothing, application of repellents, and indoor insecticide spraying), drug prophylaxis has been recommended using a combination of 100 mg of chloroquine and 200 mg of proguanil chlorhydrate (CQ + PG) in a single capsule manufactured by the French Health Army Service. Initially this policy led to a significant decrease in malaria cases among French soldiers. However the incidence of malaria rose in 1995 and 1996. This recrudescence was attributed to poor compliance with chemoprophylaxis and to the declining efficacy of the CQ + PG combination. In response to these problems, a new policy was implemented especially in countries where cycloguanil-resistant Plasmodium falciparum incidence rate is increasing. The new chemoprophylactic regimen calls for a personal prescription of mefloquine. Doxycycline monohydrate is used in case of mefloquine contra-indication or intolerance. Combination of CQ + PG delivered in a single capsule remains a suitable chemoprophylactic regimen in Sahel countries as well as Horn of Africa.

    The need for clearly reported studies evaluating the cost of prophylaxis and its overall outcomes has been recommended from previous literature. To establish minimal ''core standards'' that can be followed when conducting and reporting economic evaluations of hemophilia prophylaxis. Ten members of the IPSG Economic Analysis Working Group participated in a consensus process using the Nominal Groups Technique (NGT). The following topics relating to the economic analysis of prophylaxis studies were addressed; Whose perspective should be taken? Which is the best methodological approach? Is micro- or macro-costing the best costing strategy? What information must be presented about costs and outcomes in order to facilitate local and international interpretation? The group suggests studies on the economic impact of prophylaxis should be viewed from a societal perspective and be reported using a Cost Utility Analysis (CUA) (with consideration of also reporting Cost Benefit Analysis [CBA]). All costs that exceed $500 should be used to measure the costs of prophylaxis (macro strategy) including items such as clotting factor costs, hospitalizations, surgical procedures, productivity loss and number of days lost from school or work. Generic and disease specific quality of lífe and utility measures should be used to report the outcomes of the study. The IPSG has suggested minimal core standards to be applied to the reporting of economic evaluations of hemophilia prophylaxis. Standardized reporting will facilitate the comparison of studies and will allow for more rational policy decisions and treatment choices.

    Conclusion: The rate of proximal DVT after TKR was low (4.5% without pharmacological prophylaxis. We advise against the use of pharmacological prophylaxis in Chinese population for TKRs because of the low risk of proximal DVT and its possible bleeding complications. Foot pump did not lower the rate of DVTfurther, and its use for DVT prophylaxis in TKR is not necessary.

    prophylaxis was received or not. Included case-control studies would need to match people who had developed endocarditis (and who were known to be at increased risk before undergoing an invasive dental procedure preceding the onset of endocarditis) with those at similar risk but who had not developed endocarditis. Outcomes of interest were mortality or serious adverse events requiring hospital admission; development of endocarditis following any dental procedure in a defined time period; development of endocarditis due to other non-dental causes; any recorded adverse events to the antibiotics; and cost implications of the antibiotic provision for the care of those patients who developed endocarditis. Two review authors independently selected studies for inclusion then assessed risk of bias and extracted data from the included study. No randomised controlled trials (RCTs), controlled clinical trials (CCTs) or cohort studies were included. One case-control study met the inclusion criteria. It collected all the cases of endocarditis in the Netherlands over two years, finding a total of 24 people who developed endocarditis within 180 days of an invasive dental procedure, definitely requiring prophylaxis according to current guidelines, and who were at increased risk of endocarditis due to a pre-existing cardiac problem. This study included participants who died because of the endocarditis (using proxies). Controls attended local cardiology outpatient clinics for similar cardiac problems, had undergone an invasive dental procedure within the past 180 days, and were matched by age with the cases. No significant effect of penicillin prophylaxis on the incidence of endocarditis could be seen. No data were found on other outcomes. There remains no evidence about whether antibiotic prophylaxis is effective or ineffective against bacterial endocarditis in people at risk who are about to undergo an invasive dental procedure. It is not clear whether the potential harms and costs of

    Elective laparoscopic cholecystectomy has very low risk for infectious complications, ranging the infection rate from 0.4% to 1.1%. Many surgeons still use routine antibiotic prophylaxis. Evaluate the real impact of antibiotic prophylaxis in elective laparoscopic cholecystectomies in low risk patients. Prospective, randomized and double-blind study. Were evaluated 100 patients that underwent elective laparoscopic cholecystectomy divided in two groups: group A (n=50), patients that received prophylaxis using intravenous Cephazolin (2 g) during anesthetic induction and group B (n=50), patients that didn't receive any antibiotic prophylaxis. The outcome evaluated were infeccious complications at surgical site. The patients were reviewed seven and 30 days after surgery. There was incidence of 2% in infection complications in group A and 2% in group B. There was no statistical significant difference of infectious complications (p=0,05) between the groups. The groups were homogeneous and comparable. The use of the antibiotic prophylaxis in laparoscopic cholecystectomy in low risk patients doesn't provide any significant benefit in the decrease of surgical wound infection.

    Background and aims. Dental procedures injuring oral tissues may induce bacterial release to blood stream that can cause infective endocarditis in susceptible patients. The aim of this study was to determine the level of knowledge of general dental practitioners (GDPs in Tabriz, Northwest of Iran, regarding endocarditis prophylaxis in cardiac patients receiving dental treatments.

    Materials and methods. This was a cross-sectional, descriptive, analytical study that included 150 GDPs. All practitioners were given a self-administered questionnaire which consisted of three parts assessing their knowledge of cardiac diseases requiring prophylaxis, dental procedures requiring prophylaxis, and antibiotic regimen for endocarditis prophylaxis. Statistical analysis of data was carried out using independent t-test, one-way ANOVA and chi-square test.

    Results. The level of knowledge among GDPs in three areas of cardiac diseases requiring prophylaxis, dental procedures requiring prophylaxis, and antibiotic regimen for endocarditis prophylaxis were 63.7%, 66.8% and 47.7%, respectively. Their overall level of knowledge regarding endocarditis prophylaxis was 59%. Association of the level of knowledge with age and practice period was statistically significant (P < 0.05. However, the level of knowledge was not significantly associated with gender or university of graduation in either of three areas evaluated (P > 0.05.

    Conclusion. According to our results, the knowledge of endocarditis prophylaxis among GDPs in Tabriz was in a moderate level. Regarding the importance of endocarditis prophylaxis in susceptible patients, it should be more emphasized in the curriculum of dental schools and continuing dental education programs.

    Antiretroviral (ARV) medicines reduce the risk of transmitting the HIV virus and are recommended as daily pre-exposure prophylaxis (PrEP) in combination with safer sex practices for HIV-negative individuals at a high risk for infection, but are underused in HIV prevention. Previous literature suggests that YouTube is extensively used to share health information. While pre-exposure prophylaxis (PrEP) is a novel and promising approach to HIV prevention, there is limited understanding of YouTube videos as a source of information on PrEP. The objective of this study was to describe the sources, characteristics, and content of the most widely viewed PrEP YouTube videos published up to October 1, 2016. The keywords "pre-exposure prophylaxis" and "Truvada" were used to find 217 videos with a view count >100. Videos were coded for source, view count, length, number of comments, and selected aspects of content. Videos were also assessed for the most likely target audience. The total cumulative number of views was >2.3 million, however, a single Centers for Disease Control and Prevention video accounted for >1.2 million of the total cumulative views. A great majority (181/217, 83.4%) of the videos promoted the use of PrEP, whereas 60.8% (132/217) identified the specific target audience. In contrast, only 35.9% (78/217) of the videos mentioned how to obtain PrEP, whereas less than one third addressed the costs, side effects, and safety aspects relating to PrEP. Medical and academic institutions were the sources of the largest number of videos (66/217, 30.4%), followed by consumers (63/217, 29.0%), community-based organizations (CBO; 48/217, 22.1%), and media (40/217, 18.4%). Videos uploaded by the media sources were more likely to discuss the cost of PrEP (PYouTube videos can be used to share reliable PrEP information with individuals. Further research is needed to identify the best practices for using this medium to promote and increase PrEP uptake. ©Aleksandar Kecojevic

More than 2 million adolescents between the age group of 10 and 19 years are living with HIV, and millions are at risk of infection. HIV risks are considerably higher among girls, especially in high-prevalence settings such as eastern and southern Africa. In addition to girls, there are other vulnerable adolescent subgroups, such as teenagers, who use intravenous (IV drugs, gay and bisexual boys, transgender youth, male sex workers, and people who fall into more than one of these categories. Pre-exposure prophylaxis (PrEP is a new intervention for people at high risk for acquiring HIV, with an estimated HIV incidence of >3%. Recent data from trials show evidence of the efficacy of PrEP as a powerful HIV prevention tool in high-risk populations, including men who have sex with men, HIV-1-serodiscordant heterosexual couples, and IV drug users. The reported efficacy in those trials of the daily use of oral tenofovir, alone or in combination with emtricitabine, to prevent HIV infection ranged from 44% to 75% and was heavily dependent on adherence. Despite the proven efficacy of PrEP in adult trials, concerns remain about its feasibility in real-life scenarios due to stigma, cost, and limited clinician experience with PrEP delivery. Recent studies are attempting to expand the inquiry into the efficacy of such HIV prophylaxis approaches in adolescent populations, but there are still many gaps in knowledge, and no

    We performed a meta-analysis to evaluate the impact of systemic antibiotic prophylaxis in hematopoietic stem cell transplantation (HSCT) recipients. We collected reports from PubMed, the Cochrane Library, EMBASE, CINAHL, and Web of Science, along with references cited therein. We included prospective, randomized studies on systemic antibiotic prophylaxis in HSCT recipients. Seventeen trials with 1453 autologous and allogeneic HSCT recipients were included. Systemic antibiotic prophylaxis was compared with placebo or no prophylaxis in 10 trials and with non-absorbable antibiotics in two trials. Systemic antibiotics other than fluoroquinolones were evaluated in five of these 12 trials. Four trials evaluated the effect of the addition of antibiotics for gram-positive bacteria to fluoroquinolones. One trial compared two different systemic antibiotic regimens: fluoroquinolones versus trimethoprim-sulfamethoxazole. As a result, systemic antibiotic prophylaxis reduced the incidence of febrile episodes (OR 0.16; 95%CI 0.09-0.30), clinically or microbiologically documented infection (OR 0.38; 95%CI 0.22-0.63) and bacteremia (OR 0.31; 95%CI 0.16-0.59) without significantly affecting all-cause mortality or infection-related mortality. Systemic antibiotic prophylaxis successfully reduced the incidence of infection. However, there was no significant impact on mortality. The clinical benefits of prophylaxis with fluoroquinolones were inconclusive because of the small number of clinical trials evaluated. Copyright © 2014 The British Infection Association.

    Full Text Available Background: Treatment of latent tuberculosis infection (LTBI is one of the essential measures for tuberculosis (TB control. The tuberculin skin test (TST is an important tool for the detection of LTBI and the identification of healthcare workers (HCWs who require chemoprophylaxis. Also, the rate of active TB should be evaluated among HCWs with and without isoniazid (INH prophylactic treatment for LTBI. Objective: To evaluate the rate of active TB disease among HCWs with or without INH prophylaxis for LTBI. Methods: We retrospectively studied the clinical records of HCWs with LTBI at the employee TB screening clinic in Bamrasnaradura Infectious Diseases Institute from January 2008 to December 2010. Voluntary INH prophylaxis was recommended by physicians and nurses at the TB clinic in case of recent positive 2-step TST. The rate of active TB disease in HCWs with and without INH prophylaxis for LTBI was evaluated and followed during a period of 5 years. As well, the compliance and adverse effects of INH prophylaxis were identified by history taking. Results: There were 29 from 113 HCWS (25.7% receiving INH prophylaxis for 6 months (23 HCWs and 9 months (6 HCWs. 2 HCWs in each 6- and 9-month group did not complete INH prophylaxis for LTBI. After 5 years of TST, no case of active TB disease was found in HCWS with or without INH prophylaxis. Moreover, no adverse drug reactions were reported. Conclusion: No active tuberculosis disease was noted between the INH treatment and the control groups.

    Oral pre-exposure prophylaxis for the prevention of HIV-1 transmission (HIV PrEP) has been widely successful as demonstrated by a number of clinical trials. However, studies have also demonstrated the need for patients to tightly adhere to oral dosing regimens in order to maintain protective plasma and tissue concentrations. This is especially true for women, who experience less forgiveness from dose skipping than men in clinical trials of HIV PrEP. There is increasing interest in long-acting (LA), user-independent forms of HIV PrEP that could overcome this adherence challenge. These technologies have taken multiple forms including LA injectables and implantables. Phase III efficacy trials are ongoing for a LA injectable candidate for HIV PrEP. This review will focus on the design considerations for both LA injectable and implantable platforms for HIV PrEP. Additionally, we have summarized the existing LA technologies currently in clinical and pre-clinical studies for HIV PrEP as well as other technologies that have been applied to HIV PrEP and contraceptives. Our discussion will focus on the potential application of these technologies in low resource areas, and their use in global women's health.

    Factor VII (fVII) deficiency is a rare congenital bleeding disorder in which fVII activity level and bleeding tendency do not completely correlate. Pregnancy and delivery present a significant haemostatic challenge to women with fVII deficiency. Treatment with recombinant factor VIIa (rfVIIa) carries a thrombotic risk and the literature is not clear whether prophylaxis is necessary prior to delivery. The aim of this study was to define management, haemorrhagic and thrombotic complications of pregnant women with fVII deficiency through a systematic review. Medical databases (PubMed, MEDLINE, CINAHL, Academic Search Premier, Cochrane Library, Web of Science and Scopus) were searched using "factor VII deficiency" and "pregnancy" or "surgery." Overall 34 articles, four abstracts, and three institutional cases were reviewed. Literature from 1953 to 2011 reported 94 live births from 62 women with fVII deficiency. The median fVII activity was 5.5%. Haemostatic prophylaxis was used in 32% of deliveries. Without prophylaxis, 40 vaginal deliveries and 16 caesarean sections were completed. The odds of receiving prophylaxis were 2.9 times higher in women undergoing caesarean section compared to vaginal delivery. Post-partum haemorrhage occurred in 10% of deliveries with prophylaxis and 13% of deliveries without prophylaxis. The fVII level did not significantly differ between women who did and did not receive prophylaxis. We present the only systematic review of the management of pregnancy in fVII deficient women. No difference in post-partum haemorrhage was seen in deliveries with and without prophylaxis. Therefore, we recommend that rfVIIa be available in the case of haemorrhage or surgical intervention, but not as mandatory prophylaxis. © 2013 John Wiley & Sons Ltd.

    Prevention of arthropathy is a major goal of hemophilia treatment. While studies in adults have demonstrated an impact of prophylaxis on the incidence of joint bleeds and patients' well-being in terms of improved quality of life (QoL), it is unclear whether or not prophylaxis influences the outcome and perception of well- of children with hemophilia. This randomized controlled study compared the efficacy of prophylaxis with episodic therapy in preventing hemarthroses and image-proven joint damage in children with severe hemophilia A (factor VIII <1%) over a 10-year time period. Forty-five children with severe hemophilia A, aged 1-7 years (median 4), with negative clinical-radiologic joint score at entry and at least one bleed during the previous 6 months, were consecutively randomized to prophylaxis with recombinant factor VIII (25 IU kg(-1) 3 × week) or episodic therapy with ≥25 IU kg(-1) every 12-24 h until complete clinical bleeding resolution. Safety, feasibility, direct costs and QoL were also evaluated. Twenty-one children were assigned to prophylaxis, 19 to episodic treatment. Children on prophylaxis had fewer hemarthroses than children on episodic therapy: 0.20 vs. 0.52 events per patient per month (P < 0.02). Plain-film radiology showed signs of arthropathy in six patients on prophylaxis (29%) vs. 14 on episodic treatment (74%) (P < 0.05). Prophylaxis was more effective when started early (≤36 months), with patients having fewer joint bleeds (0.12 joint bleeds per patient per month) and no radiologic signs of arthropathy. This randomized trial confirms the efficacy of prophylaxis in preventing bleeds and arthropathy in children with hemophilia, particularly when it is initiated early in life. © 2011 International Society on Thrombosis and Haemostasis.

    The benefit of routine chemical prophylaxis use for venous thromboembolism (VTE) prevention in skull base surgery is controversial. Chemical prophylaxis can prevent undue morbidity and mortality, however there are risks for hemorrhagic complications. Retrospective case-control. A retrospective chart review of patients who underwent surgery for vestibular schwannoma from 2011 to 2016 was performed. Patients were divided by receipt of chemical VTE prophylaxis. Number of VTEs and hemorrhagic complications (intracranial hemorrhage, abdominal hematoma, and postauricular hematoma) were recorded. One hundred twenty-six patients were identified, 55 received chemical prophylaxis, and 71 did not. All the patients received mechanical prophylaxis. Two patients developed a deep vein thrombosis (DVT) and one patient developed a pulmonary embolism (PE). All patients who developed a DVT or PE received chemical prophylaxis. There was no difference in DVT (p = 0.1886) or PE (p = 0.4365) between those who received chemical prophylaxis and those who did not. Five patients developed a hemorrhagic complication, two intracranial hemorrhage, three abdominal hematoma, and zero postauricular hematoma. All five patients with a complication received chemical prophylaxis (p = 0.00142). The relative risk of a hemorrhagic complication was 14.14 (95% CI = 0.7987-250.4307; p = 0.0778). There was a significant difference between the number of hemorrhagic complications but not between numbers of DVT or PE. Mechanical and chemical prophylaxis may lower the risk of VTE but in our series, hemorrhagic complications were observed. These measures should be used selectively in conjunction with early ambulation.

    Invasive fungal infection (IFI) is a severe complication of liver transplantation burdened by high mortality. Guidelines recommend targeted rather than universal antifungal prophylaxis based on tiers of risk. We aimed to evaluate IFI incidence, risk factors, and outcome after implementation of a simplified two-tiered targeted prophylaxis regimen based on a single broad-spectrum antifungal drug (amphotericin B). Patients presenting 1 or more risk factors according to literature were administered prophylaxis. Prospectively collected data on all adult patients transplanted in Turin from January 2011 to December 2015 were reviewed. Patients re-transplanted before postoperative day 7 were considered once, yielding a study cohort of 581 cases. Prophylaxis was administered to 299 (51.4%) patients; adherence to protocol was 94.1%. Sixteen patients developed 18 IFIs for an overall rate of 2.8%. All IFI cases were in targeted prophylaxis group; none of the non-prophylaxis group developed IFI. Most cases (81.3%) presented within 30 days after transplantation during prophylaxis; predominant pathogens were molds (94.4%). Only 1 case of candidemia was observed. One-year mortality in IFI patients was 33.3% vs 6.4% in patients without IFI (P = .001); IFI attributable mortality was 6.3%. At multivariate analysis, significant risk factors for IFI were renal replacement therapy (OR = 8.1) and re-operation (OR = 5.2). The implementation of a simplified targeted prophylaxis regimen appeared to be safe and applicable and was associated with low IFI incidence and mortality. Association of IFI with re-operation and renal replacement therapy calls for further studies to identify optimal prophylaxis in this subset of patients. © 2018 John Wiley & Sons A/S.

    Infection is a rare, serious complication following total joint arthroplasty and constitutes a considerable emotional and financial burden for patients, surgeons, and healthcare systems. Prevention of surgical site and periprosthetic joint infections is crucial. This requires knowledge of the microorganisms that commonly cause these infections, including Staphylococcus species. Selection of the appropriate antibiotic regimen to treat infection remains controversial, but cefazolin and cefuroxime are the most commonly recommended antibiotics for prophylaxis. Appropriate timing of administration before surgery, with redosing performed as needed, can help to ensure optimal antibiotic concentration during surgery. Given the increasing evidence that S aureus colonization is a risk factor for periprosthetic joint infection, an exploration of the potential benefits of preoperative S aureus carrier screening and decolonization protocols is warranted. The use of antibiotic-loaded bone cement in primary total joint arthroplasty and antibiotic powder at wound closure are other controversial topics that require additional research.

    BACKGROUND: Stress ulcer prophylaxis (SUP) may decrease the incidence of gastrointestinal bleeding in patients in the intensive care unit (ICU), but the risk of infection may be increased. In this study, we aimed to describe SUP practices in adult ICUs. We hypothesised that patient selection...... for SUP varies both within and between countries. METHODS: Adult ICUs were invited to participate in the survey. We registered country, type of hospital, type and size of ICU, preferred SUP agent, presence of local guideline, reported indications for SUP, criteria for discontinuing SUP, and concerns about...... adverse effects. Fisher's exact test was used to assess differences between groups. RESULTS: Ninety-seven adult ICUs in 11 countries participated (eight European). All but one ICU used SUP, and 64% (62/97) reported having a guideline for the use of SUP. Proton pump inhibitors were the most common SUP...

    Stress ulcer prophylaxis (SUP) is regarded as standard of care in the intensive care unit (ICU). However, recent randomized, clinical trials (RCTs) and meta-analyses have questioned the rationale and level of evidence for this recommendation. The aim of the present systematic review was to evaluate...... incidence of gastrointestinal (GI) bleeding varies considerably. Data on the incidence and severity of GI bleeding in general ICUs in the developed world as of today are lacking. The best intervention for SUP is yet to be settled by balancing efficacy and harm. In essence, it is unresolved if intensive care...... patients benefit overall from SUP. The following clinically research questions are unanswered: (1) What is the incidence of GI bleeding, and which interventions are used for SUP in general ICUs today?; (2) Which criteria are used to prescribe SUP?; (3) What is the best SUP intervention?; (4) Do intensive...

    Antibiotic prophylaxis is an important component of dermatologic surgery, and recommendations in this area should reflect the updated 2007 guidelines of the American Heart Association, the American Dental Association with the American Academy of Orthopaedic Surgeons guidelines, and recent prospective studies on surgical site infection. To provide an update on the indications for antibiotic prophylaxis in dermatologic surgery for the prevention of infective endocarditis, hematogenous total joint infection, and surgical site infection. A literature review was performed, expert consensus was obtained, and updated recommendations were created, consistent with the most current authoritative guidelines from the American Heart Association and the American Dental Association with the American Academy of Orthopaedic Surgeons. For patients with high-risk cardiac conditions, and a defined group of patients with prosthetic joints at high risk for hematogenous total joint infection, prophylactic antibiotics are recommended when the surgical site is infected or when the procedure involves breach of the oral mucosa. For the prevention of surgical site infections, antibiotics may be indicated for procedures on the lower extremities or groin, for wedge excisions of the lip and ear, skin flaps on the nose, skin grafts, and for patients with extensive inflammatory skin disease. These recommendations are not based on multiple, large-scale, prospective trials. There is a strong shift away from administration of prophylactic antibiotics in many dermatologic surgery settings, based on updated authoritative guidelines. These recommendations provide guidance to comply with the most current guidelines, modified to address dermatology-specific considerations. Managing physicians may utilize these guidelines while individualizing their approach based on all clinical considerations.

    The Surgical Care Improvement Program endorses mandatory compliance with approved intravenous prophylactic antibiotics; however, oral antibiotics are optional. We hypothesized that surgical site infection (SSI) rates may vary depending on the choice of antibiotic prophylaxis. A retrospective cohort study of elective colorectal procedures using Veterans Affairs Surgical Quality Improvement Program (VASQIP) and SSI outcomes data was linked to the Office of Informatics and Analytics (OIA) and Pharmacy Benefits Management (PBM) antibiotic data from 2005 to 2009. Surgical site infection rates by type of IV antibiotic agent alone (IV) or in combination with oral antibiotic (IV + OA) were determined. Generalized estimating equations were used to examine the association between type of antibiotic prophylaxis and SSI for the entire cohort and stratified by use of oral antibiotics. After 5,750 elective colorectal procedures, 709 SSIs (12.3%) developed within 30 days. Oral antibiotic + IV (n = 2,426) had a lower SSI rate than IV alone (n = 3,324) (6.3% vs 16.7%, p antibiotic given (p ≤ 0.0001). Generalized estimating equations adjusting for significant covariates of age, body mass index, procedure work relative value units, and operation duration demonstrated an independent protective effect of oral antibiotics (odds ratio [OR] 0.37, 95% CI 0.29 to 0.46), as well as increased rates of SSI associated with ampicillin/sulbactam (OR 2.21, 95% CI 1.37 to 3.56) and second generation cephalosporins (cefoxitin, OR 2.50, 95% CI 1.83 to 3.42; cefotetan, OR 2.70, 95% CI 1.72 to 4.22) when compared with first generation cephalosporin/metronidazole. The choice of IV antibiotic was related to the SSI rate; however, oral antibiotics were associated with reduced SSI rate for every antibiotic class. Published by Elsevier Inc.

    The public health response to an influenza pandemic or other large-scale health emergency may include mass prophylaxis using multiple points of dispensing (PODs) to deliver countermeasures rapidly to affected populations. Computer models created to date to determine "optimal" staffing levels at PODs typically assume stable patient demand for service. The authors investigated POD function under dynamic and uncertain operational environments. The authors constructed a Monte Carlo simulation model of mass prophylaxis (the Dynamic POD Simulator, or D-PODS) to assess the consequences of nonstationary patient arrival patterns on POD function under a variety of POD layouts and staffing plans. Compared are the performance of a standard POD layout under steady-state and variable patient arrival rates that may mimic real-life variation in patient demand. To achieve similar performance, PODs functioning under nonstationary patient arrival rates require higher staffing levels than would be predicted using the assumption of stationary arrival rates. Furthermore, PODs may develop severe bottlenecks unless staffing levels vary over time to meet changing patient arrival patterns. Efficient POD networks therefore require command and control systems capable of dynamically adjusting intra- and inter-POD staff levels to meet demand. In addition, under real-world operating conditions of heightened uncertainty, fewer large PODs will require a smaller total staff than many small PODs to achieve comparable performance. Modeling environments that capture the effects of fundamental uncertainties in public health disasters are essential for the realistic evaluation of response mechanisms and policies. D-PODS quantifies POD operational efficiency under more realistic conditions than have been modeled previously. The authors' experiments demonstrate that effective POD staffing plans must be responsive to variation and uncertainty in POD arrival patterns. These experiments highlight the need

    Migraine headache is a relatively common, debilitating condition that costs our healthcare system over 78 billion dollars per year. Riboflavin has been advocated as a safe, effective prophylactic therapy for the prevention of migraines. The purpose of this study was to provide a systematic review of the current role of riboflavin in the prophylaxis of migraine headache. A MEDLINE literature search inclusive of the dates 1966-2016 was performed using the search terms: riboflavin and migraine disorders. Excerpta Medica was searched from 1980 to 2016 using the search terms: riboflavin and migraine. Additionally, Web of Science was searched using the terms riboflavin and migraine inclusive of 1945-2016. Bibliographies of all relevant papers were reviewed for additional citations. We utilized the PRISMA guidelines to select English language, human, clinical trials of riboflavin as a single entity or in combination, review articles, and supporting pharmacokinetic and pharmacogenomic data assessing the efficacy and mechanism of riboflavin therapy in the prophylactic treatment of migraine headache. A total of 11 clinical trials reveal a mixed effect of riboflavin in the prophylaxis of migraine headache. Five clinical trials show a consistent positive therapeutic effect in adults; four clinical trials show a mixed effect in paediatric and adolescent patients, and two clinical trials of combination therapy have not shown benefit. Adverse reactions with riboflavin have generally been mild. Riboflavin is well tolerated, inexpensive and has demonstrated efficacy in the reduction of adult patient's migraine headache frequency. Additional data are needed, however, to resolve questions involving pharmacokinetic issues and pharmacogenomic implications of therapy. © 2017 John Wiley & Sons Ltd.

    Surgical site infection is defined as an infection related to the surgical procedure in the area of manipulation occurring within the first 30 postoperative days. The diagnostic criteria include: purulent drainage, isolation of microorganisms, and signs of infection. To describe the epidemiologic characteristics and differences among the types of prophylactic regimens associated with hospital-acquired infections at the general surgery service of a tertiary care hospital. The electronic case records of patients that underwent general surgery at a tertiary care hospital within the time frame of January 1, 2013 and December 31, 2014 were reviewed. A convenience sample of 728 patients was established and divided into the following groups: Group 1: n=728 for the epidemiologic study; Group 2: n=638 for the evaluation of antimicrobial prophylaxis; and Group 3: n=50 for the evaluation of multidrug-resistant bacterial strains in the intensive care unit. The statistical analysis was carried out with the SPSS 19 program, using the Mann-Whitney U test and the chi-square test. A total of 728 procedures were performed (65.9% were elective surgeries). Three hundred twelve of the patients were males and 416 were females. Only 3.98% of the patients complied with the recommended antimicrobial prophylaxis, and multidrug-resistant bacterial strains were found in the intensive care unit. A single prophylactic dose is effective, but adherence to this recommendation was not adequate. The prophylactic guidelines are not strictly adhered to in our environment. There was a significant association between the development of nosocomial infections from multidrug-resistant germs and admission to the intensive care unit.

    2017-01-01

    Adolescents are a critical population that is disproportionately impacted by the HIV epidemic. More than 2 million adolescents between the age group of 10 and 19 years are living with HIV, and millions are at risk of infection. HIV risks are considerably higher among girls, especially in high-prevalence settings such as eastern and southern Africa. In addition to girls, there are other vulnerable adolescent subgroups, such as teenagers, who use intravenous (IV) drugs, gay and bisexual boys, transgender youth, male sex workers, and people who fall into more than one of these categories. Pre-exposure prophylaxis (PrEP) is a new intervention for people at high risk for acquiring HIV, with an estimated HIV incidence of >3%. Recent data from trials show evidence of the efficacy of PrEP as a powerful HIV prevention tool in high-risk populations, including men who have sex with men, HIV-1-serodiscordant heterosexual couples, and IV drug users. The reported efficacy in those trials of the daily use of oral tenofovir, alone or in combination with emtricitabine, to prevent HIV infection ranged from 44% to 75% and was heavily dependent on adherence. Despite the proven efficacy of PrEP in adult trials, concerns remain about its feasibility in real-life scenarios due to stigma, cost, and limited clinician experience with PrEP delivery. Recent studies are attempting to expand the inquiry into the efficacy of such HIV prophylaxis approaches in adolescent populations, but there are still many gaps in knowledge, and no country has yet approved it for use with adolescents. The aim of this review was to identify and summarize the evidence from studies on PrEP for adolescents. We have compiled and reviewed published studies focusing on safety, feasibility, adherence to therapeutics, self-perception, and legal issues related to PrEP in people aged between 10 and 24 years.

    Objective In orthognathic surgery, antibiotics are prescribed to reduce the risk of postoperative infection. However, there is lack of consensus over the appropriate drug, the dose and duration of administration. The aim of this complex systematic review was to assess the effect of antibiotics on postoperative infections in orthognathic surgery. Methods Both systematic reviews and primary studies were assessed. Medline (OVID), The Cochrane Library (Wiley) and EMBASE (embase.com), PubMed (non-indexed articles) and Health Technology Assessment (HTA) publications were searched. The primary studies were assessed using GRADE and the systematic reviews by AMSTAR. Results Screening of abstracts yielded 6 systematic reviews and 36 primary studies warranting full text scrutiny. In total,14 primary studies were assessed for risk of bias. Assessment of the included systematic reviews identified two studies with a moderate risk of bias, due to inclusion in the meta-analyses of primary studies with a high risk of bias. Quality assessment of the primary studies disclosed one with a moderate risk of bias and one with a low risk. The former compared a single dose of antibiotic with 24 hour prophylaxis using the same antibiotic; the latter compared oral and intravenous administration of antibiotics. Given the limited number of acceptable studies, no statistical analysis was undertaken, as it was unlikely to contribute any relevant information. Conclusion With respect to antibiotic prophylaxis in orthognathic surgery, most of the studies to date have been poorly conducted and reported. Thus scientific uncertainty remains as to the preferred antibiotic and the optimal duration of administration. PMID:29385159

    Orr, Serena L; Venkateswaran, Sunita

    2014-07-01

    The literature on complementary and alternative medicine (CAM) is expanding. One of the most common conditions for which CAM is studied in the pediatric population is migraine. Nutraceuticals are a form of CAM that is being used for pediatric migraine prophylaxis. A literature search was carried out in order to identify both observational studies and randomized controlled trials on the use of nutraceuticals for the prophylaxis of pediatric migraine. Adult studies on included nutraceuticals were also reviewed. Thirty studies were reviewed on six different nutraceuticals: butterbur, riboflavin, ginkgolide B, magnesium, coenzyme Q10 and polyunsaturated fatty acids. Overall, the quality of the evidence for the use of nutraceuticals in pediatric migraine prophylaxis is poor. Further research needs to be done in order to study the efficacy of nutraceuticals for the prophylaxis of pediatric migraine. © International Headache Society 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available A complex examination detected that kalium iodide dosage 100 mkg daily promote a rapid normalization of median of ioduria in children aged 8 to 12 years. Even in a case of normal initial level of ioduria iod active at the same dosage doesn't promote an increase of median of ioduria over than optimum level. It wasn't detected any decrease of goiter frequency during 6 months of prophylaxis, while the level of some cognitive indexes (an attention and the frequency of absence from school by the reason of acute respiratory deseases significantly increased. It could be concluded, that iodine prophylaxis using iod active is more effective in mild goiter endemia combine to decrease of attention in prepubertal children. In the case of combination of moderate endemic goiter and normal cognitive function kalium iodide is more preferable in prophylaxis in children.Key words: children, iod deficiency, prophylaxis.

    The primary aim of this study was to determine whether orthopaedic trauma patients receive appropriate antibiotic prophylaxis keeping in view the results of their MRSA screening. The secondary aim was to analyse the risk of developing MRSA surgical site infection with and without appropriate antibiotic prophylaxis in those colonized with MRSA. We reviewed 400 consecutive orthopaedic trauma patient episodes. Preoperative MRSA screening results, operative procedures, prophylactic antibiotics and postoperative course were explored. In addition to these consecutive patients, the hospital MRSA database over the previous 5 years identified 27 MRSA colonized acute trauma patients requiring surgery. Of the 400 consecutive patient episodes, 395(98.7%) had MRSA screening performed on admission. However, in 236 (59.0%) cases, the results were not available before the surgery. Seven patient episodes (1.8%) had positive MRSA colonization. Analysis of 27 MRSA colonized patients revealed that 20(74%) patients did not have the screening results available before the surgery. Only 5(18.5%) received Teicoplanin and 22(81.4%) received cefuroxime for antibiotic prophylaxis before their surgery. Of those receiving cefuroxime, five (22.73%) patients developed postoperative MRSA surgical site infection (SSI) but none of those (0%) receiving Teicoplanin had MRSA SSI. The absolute risk reduction for SSI with Teicoplanin as antibiotic prophylaxis was 22.73% (CI=5.22%-40.24%) and NNT (Number Needed to Treat) was 5 (CI=2.5-19.2) CONCLUSION: Lack of available screening results before the surgery may lead to inadequate antibiotic prophylaxis increasing the risk of MRSA surgical site infection. Glycopeptide (e.g.Teicoplanin) prophylaxis should be considered when there is history of MRSA colonization or MRSA screening results are not available before the surgery. Copyright © 2017.

    Elderly, hospitalized patients suffer disproportionately from constipation; however, little data suggest that constipation prophylaxis reduces length of stay (LOS). We performed a retrospective analysis of elderly patients admitted to our hospital with congestive heart failure (CHF) to determine the effects of constipation prophylaxis on LOS. Patients ≥ 65 years old admitted with the diagnosis of CHF in 2012 were evaluated for home and hospital laxative use on admission. Our primary outcome was LOS. We used linear regression modeling to independently evaluate the impact of constipation prophylaxis on LOS. Among 618 patients who were eligible for our study, 201 (32.5%) were using laxatives at home, whereas 254 (41.1%) were started on a prophylactic laxative on admission. There was no significant difference in LOS between patients receiving prophylaxis versus those who did not (P = 0.32). Patients with home laxative use had a 1 day longer LOS compared to those without laxative use (6 vs 5, P = 0.03). Among patients with home laxative use, there were 2 days longer LOS in those who were not given constipation prophylaxis on admission (8 vs 6, P = 0.002). After multivariate adjustment, failure to use constipation prophylaxis in patients with home laxative use was the only independent predictor of increased LOS (P = 0.03). Among elderly patients admitted for CHF exacerbations, failure to use constipation prophylaxis in patients with home laxative use is associated with a significantly longer LOS. Our data suggest that routine use of bowel prophylaxis for elderly CHF patients with preexisting constipation may reduce LOS. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Surgical site infections (SSI) are nosocomial infections that cause considerable problems in orthopaedic surgery. Antibiotic prophylaxis can be used to reduce the risk for SSI. There is no universal antibiotic that can be recommended for prophylaxis in terms of coverage of all possible pathogens because of antibiotic resistance, and there are no universal recommendations for different types of patients in terms of injury type, selected operation and risk factors for development of SSI. The aim of this study was to analyse the effectiveness of antibiotic prophylaxis in surgical treatment (ORIF) of closed lower limb fractures in young, healthy patients. Patient details were collected from the patient histories. Inclusion criteria for participants were age 20-30 years, not suffering from any type of chronic disease or state that may affect postoperative infection and ISS≤9. Antibiotic prophylaxis use and outcome (SSI) were compared between two groups of patients. Data were analysed using descriptive statistics, Fisher's exact test and t-test for proportions. A total of 347 patients with closed lower limb fractures treated with ORIF met the inclusion criteria. There were 290 male and 57 female patients, with an average age of 24.47 years. Prophylactic antibiotics were given to 242 patients (69.74%); 2g ceftriaxone was administered to 88.02% of the patients who received antibiotic prophylaxis. Ten patients developed postoperative infection (eight out of 242 with antibiotic prophylaxis and two out of 105 without antibiotic prophylaxis). The difference between the two groups was not statistically significant (Fisher's exact test, P=0.749). Antibiotic prophylaxis was ineffective in preventing SSI in patients with no risk factors for SSI who were undergoing ORIF for closed lower limb fractures. Copyright © 2015 Elsevier Ltd.

    Full Text Available Background: Critically ill children admitted to pediatric intensive care unit (PICU are at increased risk of gastrointestinal bleeding due to stress related mucosal injury. Reducing gastric acid by acid suppressant medication is the accepted prophylaxis treatment, but there is not any definitive guideline for using prophylaxis in PICU patients. The present study aimed to assess the effect of Proton Pump Inhibitor (PPI and H2 Blocker (H2B prophylaxis on gastrointestinal bleeding in admitted patients of PICU, Mashhad- Iran.Materials and Methods: In this study, 100 patients admitted in PICU divided into two equal groups on the first day of admission. They received ranitidine or pantoprazole as prophylaxis of stress ulcer. Those patients who had history of gastrointestinal bleeding or coagulation disorder were excluded. 100 PICU patients who had not received prophylaxis during last 6 months retrospectively evaluated as control of the study. Data were collected as demographic characteristics, admission reason, definitive diagnosis, receiving corticosteroid and mechanical ventilation in each patient. Gastrointestinal bleeding (hematemesis, coffee ground aspirate, and melena and clinically significant gastrointestinal bleeding were daily monitored. Data analyzed through descriptive statistical tests, Chi-square, logistic regression, t-test and using SPSS-16 software.Results: Among 204 patients (control group=105 and case group=99, incidence of gastrointestinal bleeding (GB was 13.2% in which 6.9% of cases presented with clinically significant gastrointestinal bleeding (CSGB. Loss of consciousness and respiratory distress were the main reason of admission. There was no significant differences between the incidence of (GB and (CSGB in experimental and control groups (P>0.05 as well as ranitidine and pantoprazole prophylaxis (P>0.05.

    Malaria prophylaxis is usually not provided routinely for most post renal transplant recipients in malaria endemic zones. Therefore, very little information is known about the incidence and severity of this disease among the post-transplant recipients in our environment. Hence a prospective, non-randomized open label clinical trial to determine the incidence of malaria and the beneficial effect of malaria prophylaxis among renal transplant recipients in Nigeria was carried out. All seven consecutive patients who had renal transplants and returned to the unit not more than four weeks later were seen and followed up. This consisted of an initial four week period of no prophylaxis and another four weeks of prophylaxis with proguanil hydrochloride 200 mg daily. Weekly thin and thick blood films by Giemsa stain were examined and other routine investigations of liver function tests, full blood count, urea, creatinine, electrolytes and urinalysis were done. Only three out of the seven patients (42.8%) had positive smears for malaria parasites in the initial no prophylaxis phase. No malaria parasites were detected at the prophylactic phase. There was no significant difference in the results of other investigations including the renal function between the two phases. This study has shown the benefit of short term routine malaria prophylaxis among renal transplant recipients in malaria endemic zones.

  13. Cost effectiveness of prophylaxis in dental practice to prevent infective endocarditis.

    1993-01-01

    BACKGROUND--Although antimicrobial prophylaxis for infective endocarditis (IE) is common practice for many dental procedures, there is little information on whether it represents value for money. A study was performed to evaluate the effectiveness of prophylaxis for all at risk patients in routine dental practice with published data from the United Kingdom. METHODS--The risk of contracting infective endocarditis was calculated from published data to find (for high risk patients) both the annual number of deaths attributable to infective endocarditis and the number of high risk dental procedures performed without prophylaxis. Costs are estimated by examining the notes of 63 patients with proved IE during the decade 1980-90. RESULTS--Such prophylaxis is highly cost effective before dental extractions, but its value for other invasive dental procedures is unproved. It was calculated that, for every 10,000 extractions in at risk patients, appropriate prophylaxis will prevent 5.7 deaths and a further 22.85 cases of non-fatal IE. This represents a saving in the costs of hospital care of 289,600 pounds for 10,000 extractions. CONCLUSION--Prophylaxis to prevent IE in at risk patients undergoing dental extraction is highly cost effective. Net savings each year throughout the United Kingdom, that might be achieved by improving the existing proportion of such patients given antibiotics from its present level of about 50% would amount to 2.5 million pounds and would prevent over 50 deaths.

Materials and methods. In this in vitro study, class V cavities were prepared on buccal surfaces of 84 bovine teeth. The teeth were restored with Tetric N-Bond adhesive and Heliomolar composite resin. Subsequent to a thermocycling procedure and three months of storage in distilled water, the teeth were randomly assigned to four groups (n=21: (1 prophylaxis with a rubber cup and pumice; (2 prophylaxis with a brush and pumice; (3 prophylaxis with air/powder polishing device; and (4 no prophylaxis (the control group. Then the teeth were immersed in 2% basic fuchsin for 24 hours and sectioned for microleakage evaluation under a stereomicroscope. Data were analyzed using Kruskal-Wallis and Wilcoxon Signed Ranks tests. Statistical significance was defined at p<0.05. Results. There were no statistically significant differences in occlusal and gingival microleakage between the groups (p=0.996 and p=0.860, respectively. In all the groups gingival margins exhibited significantly higher microleakage values compared to occlusal margins (p<0.0005. Conclusion. Prophylaxis methods had no adverse effect on marginal leakage of microfilled composite resin restorations.

    Toxoplasmosis and infections by other opportunistic agents such as Pneumocystis jirovecii constitute life-threatening risks for patients after allogeneic hematopoietic stem cell transplantation. Trimethoprim/sulfamethoxazole (TMP-SMX) has been well established for post-transplant toxoplasmosis and pneumocystis prophylaxis, but treatment may be limited due to toxicity. We explored atovaquone as an alternative and compared it with TMP-SMX regarding toxicity and efficacy during the first 100 days after transplantation in 155 consecutive adult stem cell recipients. Eight patients with a prior history of TMP-SMX intolerance received atovaquone as first-line prophylaxis. TMP-SMX was used for 141 patients as first-line strategy, but 13 patients (9.2%) were later switched to atovaquone due to TMP-SMX toxicity or gastrointestinal symptoms. No active toxoplasmosis or active P. jirovecii infection developed under continued prophylaxis with either TMP-SMX or atovaquone. However, for reasons of TMP-SMX and/or atovaquone toxicity, 7 patients were unable to tolerate any efficacious toxoplasmosis prophylaxis and therefore obtained inhalative pentamidine as P. jirovecii prophylaxis but no toxoplasmosis prophylaxis. Importantly, 2 of these patients developed severe toxoplasmosis. In summary, atovaquone appears as a valid alternative for at least some post-transplant patients who cannot tolerate TMP-SMX. This should be further confirmed by multicenter trials. © 2015 S. Karger AG, Basel.

    The impact of surgical wound infection on public health justifies its surveillance and prevention. Our objectives were to estimate the incidence of surgical wound infection in breast procedures and assess its protocol of antibiotic prophylaxis and preoperative preparation. Observational multicentre prospective cohort study of incidence of surgical wound infection. Incidence was evaluated, stratified by National Nosocomial Infection Surveillance (NNIS) risk index and we calculated the standardized incidence ratio (SIR). The SIR was compared with Spanish rates and U.S. rates. The compliance and performance of the antibiotic prophylaxis and preoperative preparation protocol were assessed and their influence in the incidence of infection with the relative risk. Ten hospitals from the Comunidad de Madrid were included, providing 592 procedures. The cumulative incidence of surgical wound infection was 3.89% (95% CI: 2.3-5.5). The SIR was 1.82 on the Spanish rate and 2.16 on the American. Antibiotic prophylaxis was applied in 97.81% of cases, when indicated. The overall performance of antibiotic prophylaxis was 75%, and 53% for preoperative preparation. No association was found between infection and performance of prophylaxis or preoperative preparation (P>.05). Our incidence is within those seen in the literature although it is somewhat higher than the national surveillance programs. The performance of prophylaxis antibiotic must be improved, as well as the recording of preoperative preparation data. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    BACKGROUND Preexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others. METHODS In this randomized, double-blind, placebo-controlled trial, we assigned 2120 HIV-negative women in Kenya, South Africa, and Tanzania to receive either a combination of tenofovir disoproxil fumarate and emtricitabine (TDF–FTC) or placebo once daily. The primary objective was to assess the effectiveness of TDF–FTC in preventing HIV acquisition and to evaluate safety. RESULTS HIV infections occurred in 33 women in the TDF–FTC group (incidence rate, 4.7 per 100 person-years) and in 35 in the placebo group (incidence rate, 5.0 per 100 person-years), for an estimated hazard ratio in the TDF-FTC group of 0.94 (95% confidence interval, 0.59 to 1.52; P = 0.81). The proportions of women with nausea, vomiting, or elevated alanine aminotransferase levels were significantly higher in the TDF–FTC group (P = 0.04, P<0.001, and P = 0.03, respectively). Rates of drug discontinuation because of hepatic or renal abnormalities were higher in the TDF–FTC group (4.7%) than in the placebo group (3.0%, P = 0.051). Less than 40% of the HIV-uninfected women in the TDF–FTC group had evidence of recent pill use at visits that were matched to the HIV-infection window for women with seroconversion. The study was stopped early, on April 18, 2011, because of lack of efficacy. CONCLUSIONS Prophylaxis with TDF–FTC did not significantly reduce the rate of HIV infection and was associated with increased rates of side effects, as compared with placebo. Despite substantial counseling efforts, drug adherence appeared to be low. (Supported by the U.S. Agency for International Development and others; FEM-PrEP ClinicalTrials.gov number, NCT00625404.)

    Obesity is one of the well-documented risk factors of pelvic floor disorders (PFDs). The PFDs include urinary and fecal incontinence (UI, FI) and pelvic organ prolapse (POP). Surgery-induced weight loss improves different kinds of incontinence as well as POP symptoms. However, there is a lack of evidence how bariatric surgery influences pelvic floor anatomy and function in women without previous PFDs and whether it may be concerned as PFD prophylaxis tool. The present analysis is a prospective, non-randomized case-control study from January 2014 to September 2017. Participants underwent pelvic floor ultrasound examination with bladder neck position estimation at rest, during levator ani tension, and at Valsalva maneuver before surgery and 12-18 months after. Pelvic organ prolapse quantification (POPQ) > 2 stage and PFD complaints were the exclusion criteria. Fifty-nine patients underwent bariatric surgery (57 sleeve gastrectomy and 2 gastric bypass). Mean BMI decreased from 43.8 ± 5.9 to 29 ± 4.6 kg/m 2 after surgery (p betterment of bladder neck position at rest, tension, and Valsalva maneuver in women without PFDs. We postulate that bariatric surgery may be a tool for PFD prevention. It does not improve levator ani function and does not limit bladder neck mobility, which implicates that it has no influence on preexisting pelvic dysfunction.

  19. Natural cocoa as diet-mediated antimalarial prophylaxis.

    2010-05-01

    The Maya of Central America are credited with the first consumption of cocoa and maintaining its ancient Olmec name kakawa translated in English as "God Food", in recognition of its multiple health benefits. The legend of cocoa is receiving renewed attention in recent years, on account of epidemiological and scientific studies that support its cardiovascular health benefits. Increasing numbers of scientific reports corroborating cocoa's antiquated reputation as health food persuaded this author to promote regular consumption of cocoa in Ghana since 2004. Cocoa is readily available in Ghana; the country is the second largest producer accounting for 14% of the world's output. Numerous anecdotal reports of reduced episodic malaria in people who daily drink natural unsweetened cocoa beverage prompted a search for scientific mechanisms that possibly account for cocoa's antimalarial effects. This paper presents the outcome as a hypothesis. Internet search for literature on effects of cocoa's ingredients on malaria parasites and illness using a variety of search tools. Evidential literature suggests five mechanisms that possibly underpin cocoa's anecdotal antimalarial effects. (i) Increased availability of antioxidants in plasma, (ii) membrane effects in general and erythrocyte membrane in particular, (iii) increased plasma levels of nitric oxide, (iv) antimalarial activity of cocoa flavanoids and their derivatives, and (v) boosted immune system mediated by components of cocoa including cocoa butter, polyphenols, magnesium, and zinc. A hypothesis is formulated that cocoa offers a diet-mediated antimalarial prophylaxis; and an additional novel tool in the fight against the legendary scourge.

    Nonoccupational postexposure prophylaxis (nPEP) for HIV following sexual assault may decrease the likelihood of HIV transmission. The purpose of this exploratory chart review study was to examine factors associated with patients accepting post-sexual assault nPEP at three forensic nurse examiner programs in urban settings. Forensic nursing charts of patients presenting for acute sexual assault care were reviewed as part of a mixed-methods study. Patients assaulted by more than one or an unknown number of assailants were over 12 times more likely to accept the offer of nPEP (adjusted odds ratio [aOR] = 12.66, 95% CI [2.77, 57.82]). In cases where no condom was used (aOR = 8.57, 95% CI [1.59, 46.10]) or when any injury to the anus or genitalia was noted (aOR = 4.10, 95% CI [1.57, 10.75]), patients were more likely to accept nPEP. Patients with any injury to the face or head were less likely to initiate nPEP (aOR = 0.32, 95% CI [0.11, 0.97]). This study is an important first step in understanding factors associated with nPEP acceptance after sexual assault.

    Glucocorticoid-induced osteoporosis (GIOP) is the most common form of secondary osteoporosis, yet few patients receive proper measures to prevent its development. We retrospectively searched prescription records to determine if patients receiving oral prednisolone were receiving prophylaxis or treatment for osteopenia and osteoporosis. Patients who were prescribed greater or equal to 7.5 milligrams of prednisolone for 6 months or longer during a 6- month period were identified through the prescription monitoring system. Demographic and clinical data were extracted from the patient records, and dual energy x-ray absorptiometry (DEXA) scans were retrieved, when available. Use of oral calcium, vitamin D and anti-resorptives was recorded. One hundred males and 65 females were receiving oral prednisolone for a mean (SD) duration of 40.4 (29.9) months in males and 41.2 (36.4) months in females. Twenty-one females (12.7%) and 5 (3%) males had bone mineral density measured by DEXA. Of those, 10 (47.6%) females and 3 (50%) males were osteoporotic and 11(52.4%) females and 2 (40%) males were osteopenic. Calcium and vitamin D were prescribed to the majority of patients (60% to 80%), but none were prescribed antiresorptive/anabolic therapy. Patients in this study were neither investigated properly nor treated according to the minimum recommendations for the management of GIOP. Physician awareness about the prevention and treatment of GIOP should be a priority for the local health care system. (author)

  2. Prosthetic joint infection, dental treatment and antibiotic prophylaxis

    2009-06-01

    Full Text Available Current international and national prophylactic antibiotic regimens have been analyzed in respect of the prevention of bacteremia after dental and surgical procedures and, therefore, of joint prosthesis infection. This information was used to formulate guidelines for the Department of Maxillofacial and Oral Surgery. Publications since 2003 were used in this research. In addition, recommendations of accredited institutions and associations were examined. These included the guidelines of the American Dental Association in association with the American Academy of Orthopaedic Surgeons (2003, the American Heart Association (2007, the Working Party of the British Society for Antimicrobial Chemotherapy (2006 and the Australian Dental Guidelines (2005. No guidelines published by any institution in South Africa were found. The general rationale for the use of antibiotic prophylaxis for surgical (including dental interventions is that those procedures may result in a bacteremia that may cause infection in joint prostheses. Antibiotics, however, should therefore be administered to susceptible patients, e.g. immunocompromised patients, prior to the development of bacteremia. The guidelines recommended for use in South Africa are based solely on those used outside South Africa. South Africa is regarded as a developing country with its own population and demographic characteristics. Eleven percent of our population is infected with HIV, and a specific guideline for prophylactic antibiotic treatment is, therefore, essential.

    The prophylactic use of antibiotics can only be justified when clinical benefits on relevant patient outcomes, such as morbidity or mortality, cost-effectiveness, and absence of immediate emergence of antibiotic resistance have been unequivocally demonstrated. In some intensive care unit (ICU) patients, antibiotic prophylaxis is used as part of selective digestive tract decontamination (SDD) and selective oropharyngeal decontamination (SOD). Recent trials in ICUs with low levels of antibiotic resistance strongly suggest that both regimens reduce the incidence of ICU-acquired infections and improve patient survival. Naturally, the unique microbial ecology of such settings reduce generalizability of results. Therefore, the routine use of SOD and SDD remains highly controversial, especially in ICUs with higher levels of antibiotic resistance. Moreover, convincing evidence is still missing on several important aspects related to efficacy and safety. Despite numerous trials, effects of SDD and SOD on antibiotic resistance during and after decolonization treatment have still been insufficiently investigated, and existing results are contradicting. Furthermore, the effects of both regimens on the non-culturable part of the intestinal flora remain unknown. Finally, cost-effectiveness has not been thoroughly investigated, and prices of the antimicrobial agents that have been used have increased dramatically in recent years. In this review, important knowledge gaps that so far prevent the widespread use of SDD and SOD will be addressed.

    To describe the effectiveness of containment of novel influenza A(H1N1) infection at a summer camp. Targeted use of oseltamivir phosphate by individuals in close contact with influenza-confirmed cases. Boys' camp in Alabama in July 2009. A total of 171 campers, 48 camp counselors, and 27 camp staff. Campers with confirmed influenza received oseltamivir and were immediately isolated and sent home. All boys and counselors in the infected child's adjoining cabins received prophylactic oseltamivir for 10 days, including 8 campers at higher risk for influenza infection (eg, those with asthma, seizure disorder, or diabetes). Alcohol-based hand sanitizer was provided at each of the daily activities, in the boys' cabins, and in the dining hall, and counselors were educated by the medical staff on the spread of influenza and its prevention through good hand hygiene. All cabins, bathrooms, and community sports equipment were sprayed or wiped down with disinfectant each day. Main Outcome Measure Virologic confirmation of influenza. Three of the 171 campers tested positive for influenza A during the course of the 2-week fourth session, for an attack rate of 1.8%. The probability of observing 3 or fewer infected campers if the attack rate was 12% is less than 1 in 10,000,000 (P hand sanitization and surface decontamination, a targeted approach to antiviral prophylaxis contained the spread of influenza in a summer camp setting.

A descriptive design, semistructured self-administered questionnaire was used for the study. The study showed that 48% of respondents had knowledge on the meaning of PEP, only 39.39% respondents were aware of the first aid management getting needle prick injury, 60% were aware of the best time to start PEP of HIV and 56% respondents had knowledge about the time schedule of HIV test after exposure. Although the respondents answered most of the questions correctly, they had knowledge deficit in certain areas. The respondents’ knowledge in this regard needs to be improved with time-to-time awareness program and periodic training, which ultimately helps to decrease the transmission of disease and reduces mortality and morbidity.

    HIV Pre-Exposure Prophylaxis (PrEP) consists of administering antiretroviral drugs to seronegative individuals with high risk practices. The aim of the study was to describe the characteristics of recent seroconverted HIV patients in order to determine the profile of the appropriate candidates for PrEP. A descriptive study of all patients diagnosed with HIV infection in 2014, and who had achieved a documented negative serology over the previous 12 months. A specific form was completed to determine the sociodemographic, behavioural, and clinical features, with complementary tests being performed for other sexually transmitted infections. Almost all (98.4%) of the 61 recent seroconverted were men who have sex with men, and aged between 20 to 39 years (88.5%). They also had a background of sexually transmitted infections (80.3%), performed multiple and unprotected sexual practices (82.7%), and under the effect of recreational drugs (87%). The evaluation of the risk factors for HIV infection in seronegative patients should enable the appropriate candidates for PrEP to be identified.

    Full Text Available Objectives: To review existing data on Pre-Exposure Prophylaxis (PrEP for prevention of HIV infection, including the role of medical male circumcision, oral administration of antiretroviral drugs and topical microbicides. Data Sources: PubMed and www.clinicaltrials.gov. Review Methods: Comprehensive review. Results: Medical male circumcision has been shown to prevent 48-60% of new HIV-1 infections. The efficacy rate of antiretroviral drugs given per os to prevent HIV infection varies in direct association with the adherence rate (62.2% in TDF2 study with 84% adherence; 44% in iPrEx study with <50% adherence; 48% in Bangkok study with 67% adherence; 67-75% in Partners PrEP study with 82% adherence; and 6% in FEM-PrEP study with 40% adherence. As for the use of topic microbicides, the CAPRISA 004 study showed 39% reduction in HIV infection using a 1% tenofovir gel. On the other hand, PRO2000 gel showed a modest reduction of 30% which was not statistically significant. Conclusions: The studies suggest that medical male circumcision is highly cost-effective at preventing HIV infection but requires careful communication strategies to be successful. PrEP using antiretroviral drugs is also very effective but it is highly dependent on the adherence rate. As for topical microbicides, 1% tenofovir gel is currently the only promising option.

    Full Text Available Purpose: To describe prophylactic patterns employed against endophthalmitis after cataract surgery in Iran. Methods: This cross-sectional study included 486 ophthalmologists filling in a self-administered questionnaire during the 20 th Annual Congress of the Iranian Society of Ophthalmology in December 2010, Tehran, working in both private and academic medical centers. Prophylactic measures used preoperatively, intraoperatively and postoperatively and self-reported rates of endophthalmitis were assessed as the main outcome measurements. Results: In the preoperative phase, 75.5% of surgeons used povidone-iodine in the conjunctival sac and 71.4% of them did not use antibiotics. The rate of intraoperative prophylaxis was 61.9% either in the form of intracameral antibiotics or subconjunctival injection (mostly cephazolin or gentamicin. Only 7.8% of participants used intracameral cephalosporins. Postoperative antibiotics [mostly chloramphenicol (57% and ciprofloxacin (28%] were used by 94.2% of surgeons. On average, ten years of practice were required to observe one case of endophthalmitis. Conclusion: The surgeons in present setting used various prophylactic regimens against endophthalmitis after cataract surgery. Setting a local and evidence-based clinical practice guideline seems necessary.

    Leprosy has a wide range of clinical and socio-economic consequences. India, Indonesia and Nepal contribute significantly to the global leprosy burden. After integration, the health systems are pivotal in leprosy service delivery. The Leprosy Post Exposure Prophylaxis (LPEP) program is ongoing to investigate the feasibility of providing single dose rifampicin (SDR) as post-exposure prophylaxis (PEP) to the contacts of leprosy cases in various health systems. We aim to compare national leprosy control programs, and adapted LPEP strategies in India, Nepal and Indonesia. The purpose is to establish a baseline of the health system's situation and document the subsequent adjustment of LPEP, which will provide the context for interpreting the LPEP results in future. The study followed the multiple-case study design with single units of analysis. The data collection methods were direct observation, in-depth interviews and desk review. The study was divided into two phases, i.e. review of national leprosy programs and description of the LPEP program. The comparative analysis was performed using the WHO health system frameworks (2007). In all countries leprosy services including contact tracing is integrated into the health systems. The LPEP program is fully integrated into the established national leprosy programs, with SDR and increased documentation, which need major additions to standard procedures. PEP administration was widely perceived as well manageable, but the additional LPEP data collection was reported to increase workload in the first year. The findings of our study led to the recommendation that field-based leprosy research programs should keep health systems in focus. The national leprosy programs are diverse in terms of organizational hierarchy, human resource quantity and capacity. We conclude that PEP can be integrated into different health systems without major structural and personal changes, but provisions are necessary for the additional monitoring

    Current guidelines recommend upper endoscopic screening for patients with hepatic cirrhosis and primary prophylaxis with a nonselective beta-blocker for those with large varices. However, only 25% of cirrhotics develop large varices. Thus, the aim of this study is to evaluate the most cost-effective approach for primary prophylaxis of variceal hemorrhage. Using a Markov model, we compared the costs and clinical outcomes of three strategies for primary prophylaxis of variceal bleeding. In the first strategy, patients were given a beta-blocker without undergoing upper endoscopy. In the second strategy, patients underwent upper endoscopic screening; those found to have large varices were treated with a beta-blocker. In the third strategy, no prophylaxis was used. Selected sensitivity analyses were performed to validate outcomes. Our results show screening prophylaxis was associated with a cost of $37,300 and 5.72 quality-adjusted life yr (QALYs). Universal prophylaxis was associated with a cost of $34,100 and 6.65 QALYs. The no prophylaxis strategy was associated with a cost of $36,600 and 4.84 QALYs. The incremental cost-effectiveness ratio was $800/QALY for the endoscopic strategy relative to the no prophylaxis strategy. Screening endoscopy was cost saving when the compliance, bleed risk without beta-blocker, and variceal bleed costs were increased, and when the discount rate, bleed risk on beta-blockers, and cost of upper endoscopy were decreased. In contrast, the universal prophylaxis strategy was persistently cost saving relative to the no prophylaxis strategy. In comparing the strategies, sensitivity analysis on the death rates from variceal hemorrhage did not alter outcomes. Our results provide economic and clinical support for primary prophylaxis of esophageal variceal bleeding in patients with hepatic cirrhosis. Universal prophylaxis with beta-blocker is preferred because it is consistently associated with the lowest costs and highest QALYs.

    Guidelines advise primary granulocyte colony-stimulating factor (G-CSF) prophylaxis during chemotherapy if risk of febrile neutropenia (FN) is more than 20%, but this comes with considerable costs. We investigated the incremental costs and effects between two treatment strategies of primary pegfilgrastim prophylaxis. Our economic evaluation used a health care perspective and was based on a randomized study in patients with breast cancer with increased risk of FN, comparing primary G-CSF prophylaxis throughout all chemotherapy cycles (G-CSF 1-6 cycles) with prophylaxis during the first two cycles only (G-CSF 1-2 cycles). Primary outcome was cost effectiveness expressed as costs per patient with episodes of FN prevented. The incidence of FN increased from 10% in the G-CSF 1 to 6 cycles study arm (eight of 84 patients) to 36% in the G-CSF 1 to 2 cycles study arm (30 of 83 patients), whereas the mean total costs decreased from € 20,658 (95% CI, € 20,049 to € 21,247) to € 17,168 (95% CI € 16,239 to € 18,029) per patient, respectively. Chemotherapy and G-CSF determined 80% of the total costs. As expected, FN-related costs were higher in the G-CSF 1 to 2 cycles arm. The incremental cost effectiveness ratio for the G-CSF 1 to 6 cycles arm compared with the G-CSF 1 to 2 cycles arm was € 13,112 per patient with episodes of FN prevented. We conclude that G-CSF prophylaxis throughout all chemotherapy cycles is more effective, but more costly, compared with prophylaxis limited to the first two cycles. Whether G-CSF prophylaxis throughout all chemotherapy cycles is considered cost effective depends on the willingness to pay per patient with episodes of FN prevented.

    Antimicrobial prophylaxis is one of the main safety measures to be enforced when implanting any medical device; surveys of practice, however, have found poor compliance. This study is based on analysis of 153 dedicated in-depth analysis forms sent to orthopedic surgeons who had reported an antimicrobial prophylaxis-related near-miss event (NME) during the year 2008 as part of their certification report to the official organization, Orthorisq (orthopaedic Patient safety risk management agency). Antimicrobial prophylaxis guidelines exist in 95% of French centers, but in 14% are not available in the right place. 88% of orthopedic surgeons consider them well-adapted to their practice. Most declarations follow fortuitous discovery by the surgeon of an immediate peri-operative malfunction. Human causes were found in 92% of declarations, general organizational causes in 50% and material causes in 28%. Regarding corrective action, 65% of respondents reported implementing a second-order procedure, and only 20% were able to resume truly regular antimicrobial prophylaxis. The main reason for poor or non-performance of antimicrobial prophylaxis was "omission by negligence or oversight", reported in 56% of declarations. Proposals for improvement were: revised antimicrobial prophylaxis guidelines specifying "who does what"; guideline awareness checks on new, temporary and locum-tenens staff; patient involvement in personal data collection; and implementation of a check-list in line with WHO and French Health Authority recommendations. These improvement proposals were taken on board in the antimicrobial prophylaxis consensus update currently being drawn up by the French Society for Anesthesia and Intensive Care.

    Full Text Available The research is focused on revealing the TORCH-infections prophylaxis problems during preconception period and culture of personal infection safety among pregnant women. The research involved 2060 women. Epidemiological monitoring was accompanied by a social survey of the Perinatal Center patients using the continuous sampling method. The problems of the population’s response adequacy regarding the dangers of TORCH-infection are presented on the basis of questionnaire survey of 55 pregnant women – patients of the Perinatal Center. Sociological explication of the problems of TORCH-infections prophylaxis revealed the positive and negative behavioral stereotypes of the Perm Region population from the point of view of assuring the personal infection safety. The positive stereotypes include cleanliness and vitamin prophylaxis practice. The regional hygienic culture can be developed by increased involvement in sport, immunological prophylaxis propaganda, safe sex, helminth prophylaxis in pets and regular tooth brushing. The survey has explicated the common negative behavour stereotypes leading to toxoplasmosis contamination during pregnancy. Only a half of the surveyed women avoid the intake of meat that did not undergo sufficient heat treatment, 72.7 % of respondents cannot be relieved from the duties of cleaning the cat’s toilet. The rating made on the basis of the survey concerning the popularity of measures assuring personal infection safety has shown a neglectful attitude of population towards the immunological prophylaxis and modern medical products affecting the immune system, that inevitably leads to problems with compliance of pregnant women to vaccination and immunological correction by immune modulators during treatment of the revealed infectious diseases. We found a mismatch between the behavioral stereotypes of the Perm Region population in ensuring personal infection safety and the academic principles of TORCH-infections prevention

    Full Text Available Abstract Background Preterm birth is a global problem, with a prevalence of 8 to 12% depending on location. Several large trials and systematic reviews have shown progestogens to be effective in preventing or delaying preterm birth in selected high risk women with a singleton pregnancy (including those with a short cervix or previous preterm birth. Although an improvement in short term neonatal outcomes has been shown in some trials these have not consistently been confirmed in meta-analyses. Additionally data on longer term outcomes is limited to a single trial where no difference in outcomes was demonstrated at four years of age of the child, despite those in the “progesterone” group having a lower incidence of preterm birth. Methods/Design The OPPTIMUM study is a double blind randomized placebo controlled trial to determine whether progesterone prophylaxis to prevent preterm birth has long term neonatal or infant benefit. Specifically it will study whether, in women with singleton pregnancy and at high risk of preterm labour, prophylactic vaginal natural progesterone, 200 mg daily from 22 – 34 weeks gestation, compared to placebo, improves obstetric outcome by lengthening pregnancy thus reducing the incidence of preterm delivery (before 34 weeks, improves neonatal outcome by reducing a composite of death and major morbidity, and leads to improved childhood cognitive and neurosensory outcomes at two years of age. Recruitment began in 2009 and is scheduled to close in Spring 2013. As of May 2012, over 800 women had been randomized in 60 sites. Discussion OPPTIMUM will provide further evidence on the effectiveness of vaginal progesterone for prevention of preterm birth and improvement of neonatal outcomes in selected groups of women with singleton pregnancy at high risk of preterm birth. Additionally it will determine whether any reduction in the incidence of preterm birth is accompanied by improved childhood outcome. Trial

    Antibiotic prophylaxis is the most suitable tool for preventing surgical site infection. This study assessed compliance with antibiotic prophylaxis in surgery for acute appendicitis, and the effect of this compliance on surgical site infection. Prospective cohort study to evaluate compliance with antibiotic prophylaxis protocol in appendectomies. An assessment was made of the level of compliance with prophylaxis, as well as the causes of non-compliance. The incidence of surgical site infection was studied after a maximum incubation period of 30 days. The relative risk adjusted with a logistic regression model was used to assess the effect of non-compliance of prophylaxis on surgical site infection. The study included a total of 930 patients. Antibiotic prophylaxis was indicated in all patients, and administered in 71.3% of cases, with an overall protocol compliance of 86.1%. The principal cause of non-compliance was time of initiation. Cumulative incidence of surgical site infection was 4.6%. No relationship was found between inadequate prophylaxis compliance and infection (relative risk=0.5; 95% CI: 0.1-1.9) (P>.05). Compliance of antibiotic prophylaxis was high, but could be improved. No relationship was found between prophylaxis compliance and surgical site infection rate.

    Purpose The purpose of this paper is to improve surgical antimicrobial prophylaxis (SAP) prescribing in orthopaedic surgery using the model for improvement framework. Design/methodology/approach Orthopaedic patients receiving joint replacements, hip fracture repairs or open-reduction internal-fixation procedures were included. Antimicrobial(s); dose, time of administration and duration of SAP were evaluated for appropriateness based on the local SAP guidelines. After baseline data collection, a driver diagram was constructed with interventions devised for plan-do-study-act cycles. Data were fed back weekly using a point prevalence design (PPD). Interventions included SAP guideline changes, reminders and tools to support key messages. Findings SAP in 168 orthopaedic surgeries from 15 June 2016 to 31 January 2017 was studied. Prescribing appropriateness improved from 20 to 78 per cent. Junior doctor changeover necessitated additional education and reminders. Practical implications Due to constant staff changeover; continuous data collection, communication, education and reminders are essential to ensure continuous compliance with clinical guidance. Patients with hip fractures are difficult to weigh, requiring weight estimation for weight-based antimicrobial dosing. Unintended consequences of interventions included the necessity to change pre-operative workflow to accommodate reconstitution time of additional antimicrobials and inadvertent continuation of new antimicrobials post-operatively. Originality/value Rather than perform the traditional retrospective focused audit, we established a prospective, continuous, interventional quality improvement (QI) project focusing on internal processes within the control of the project team with rapid cyclical changes and interventions. The weekly PPD was pragmatic and enabled the QI project to be sustained with no additional resources.

  17. Use of Probiotics as Prophylaxis for Postoperative Infections

    2011-05-01

    Full Text Available Postoperative bacterial infections are common despite prophylactic administration of antibiotics. The wide-spread use of antibiotics in patients has contributed to the emergence of multiresistant bacteria. A restricted use of antibiotics must be followed in most clinical situations. In surgical patients there are several reasons for an altered microbial flora in the gut in combination with an altered barrier function leading to an enhanced inflammatory response to surgery. Several experimental and clinical studies have shown that probiotics (mainly lactobacilli may reduce the number of potentially pathogenia bacteria (PPM and restore a deranged barrier function. It is therefore of interest to test if these abilities of probiotics can be utilized in preoperative prophylaxis. These factors may be corrected by perioperative administration of probiotics in addition to antibiotics. Fourteen randomized clinical trials have been presented in which the effect of such regimens has been tested. It seems that in patients undergoing liver transplantation or elective surgery in the upper gastrointestinal tract prophylactic administration of different probiotic strains in combination with different fibers results in a three-fold reduction in postoperative infections. In parallel there seems to be a reduction in postoperative inflammation, although that has not been studied in a systematic way. The use of similar concepts in colorectal surgery has not been successful in reducing postoperative infections. Reasons for this difference are not obvious. It may be that higher doses of probiotics with longer duration are needed to influence microbiota in the lower gastrointestinal tract or that immune function in colorectal patients may not be as important as in transplantation or surgery in the upper gastrointestinal tract. The favorable results for the use of prophylactic probiotics in some settings warrant further controlled studies to elucidate potential

    2015-01-01

    Purpose of review To discuss non-daily pre-exposure prophylaxis (PrEP) modalities that may provide advantages compared with daily PrEP in cost and cumulative toxicity, but may have lower adherence forgiveness. Recent Findings Animal models have informed our understanding of early viral transmission events, which help guide event-driven PrEP dosing strategies. These models indicate early establishment of viral replication in rectal or cervicovaginal tissues, so event-driven PrEP should rapidly deliver high mucosal drug concentrations within hours of the potential exposure event. Macaque models have demonstrated the high biological efficacy for event-driven dosing of oral tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) against both vaginal and rectal virus transmission. In humans, the IPERGAY study demonstrated 86% efficacy for event-driven oral TDF/FTC dosing among men who have sex with men (MSM), while no similar efficacy data are available on women or heterosexual men. The HPTN 067 study showed that certain MSM populations adhere well to non-daily PrEP while other populations of women adhere more poorly to non-daily versus daily regimens. Pharmacokinetic studies following oral TDF/FTC dosing in humans, indicate that TFV-diphosphate (the active form of TFV) accumulates to higher concentrations in rectal versus cervicovaginal tissue but non-adherence in trials complicates the interpretation of differential mucosal drug concentrations. Summary Event-driven dosing for TFV-based PrEP has promise for HIV prevention in MSM. Future research of event-driven PrEP in women and heterosexual men should be guided by a better understanding of the importance of mucosal drug concentrations for PrEP efficacy and its sensitivity to adherence.

    Our primary aim was to explore themes regarding attitudes toward HIV pre-exposure prophylaxis (PrEP) among young transgender women (YTW), in order to develop a theoretical model of PrEP uptake in this population disproportionally affected by HIV. Qualitative study nested within a mixed-method study characterizing barriers and facilitators to health services for YTW. Participants completed an in-depth interview exploring awareness of and attitudes toward PrEP. Key themes were identified using a grounded theory approach. Participants (n = 25) had a mean age of 21.2 years (standard deviation 2.2, range 17-24) and were predominately multiracial (36%) and of HIV-negative or unknown status (68%). Most participants (64%) reported prior knowledge of PrEP, and 28% reported current use or intent to use PrEP. Three major content themes that emerged were variability of PrEP awareness, barriers and facilitators to PrEP uptake, and emotional benefits of PrEP. Among participants without prior PrEP knowledge, participants reported frustration that PrEP information has not been widely disseminated to YTW, particularly by health care providers. Attitudes toward PrEP were overwhelmingly positive; however, concerns were raised regarding barriers including cost, stigma, and adherence challenges. Both HIV-positive and negative participants discussed emotional and relationship benefits of PrEP, which were felt to extend beyond HIV prevention alone. A high proportion of YTW in this study had prior knowledge of PrEP, and attitudes toward PrEP were positive among participants. Our findings suggest several domains to be further explored in PrEP implementation research, including methods of facilitating PrEP dissemination and emotional motivation for PrEP uptake.

    ABSTRACT Hepatitis A (HA) has been a vaccine-preventable disease since 1995. In Catalonia, a universal combined hepatitis A+B vaccination program of preadolescents was initiated at the end of 1998. However, outbreaks are reported each year and post-exposure prophylaxis (PEP) with hepatitis A virus (HAV) vaccine or immunoglobulin (IG) is recommended to avoid cases. The aim of this study was to assess the effectiveness of HAV vaccine and IG in preventing hepatitis A cases in susceptible exposed people. A retrospective cohort study of contacts of HA cases involved in outbreaks reported in Catalonia between January 2006 and December 2012 was made. The rate ratios and 95% confidence intervals (CI) of HA in susceptible contacts receiving HAV or IG versus those without PEP were calculated. There were 3550 exposed persons in the outbreaks studied: 2381 received one dose of HAV vaccine (Hepatitis A or hepatitis A+B), 190 received IG, and 611 received no PEP. 368 exposed subjects received one dose of HAV vaccine and IG simultaneously and were excluded from the study. The effectiveness of PEP was 97.6% (95% CI 96.2–98.6) for HAV vaccine and 98.3% (95% CI 91.3–99.9) for IG; the differences were not statistically significant (p = 0.36). The elevated effectiveness of HAV vaccination for PEP in HA outbreaks, similar to that of IG, and the long-term protection of active immunization, supports the preferential use of vaccination to avoid secondary cases.

    Antibiotic prophylaxis is frequently administered after liver resection to prevent postoperative infections. However, very few studies have examined the usefulness of antibiotic prophylaxis after liver resection. A randomized controlled trial was conducted to evaluate the postoperative antibiotic prophylaxis in patients after liver resection. A total of 241 patients scheduled to undergo liver resection were randomly assigned to the non-postoperative antibiotic group (n = 95) or the antibiotic group (n = 95). The antibiotic group was given flomoxef sodium every 12 hours for 3 days after the operation. The end point was signs of infection, surgical site infection, or infectious complications. There were no significant differences between the 2 groups in signs of infection (21.3% vs 25.5%, P = .606), the incidence of systemic inflammatory response syndrome (11.7% vs 17.0%, P = .406), infectious complications (7.5% vs 17.0%, P = .073), surgical site infection (10.6% vs 13.8%, P = .657), and remote site infection (2.1% vs 8.5%, P = .100). Postoperative antibiotic prophylaxis cannot prevent postoperative infections after liver resection, and it is thought that antibiotic prophylaxis is unnecessary and costly.

    Postoperative nausea and vomiting (PONV) is common after general anesthesia and are reported by approximately 20% to 25% of all patients and up to 39% of patients undergoing neurosurgical procedures. The most common standard prophylaxis is a single application of 4 mg of dexamethasone before initiating anesthesia. Dexamethasone is known to suppress adreno-corticotroph hormone and cortisol levels. The objective was to find out whether this prophylaxis has an effect on the postoperative levels of cortisol in patients undergoing transsphenoidal pituitary surgery, and therefore simulates pituitary deficiency. A retrospective analysis of the files of 136 consecutive patients who were operated during a course of 6 months were included. Nineteen patients with a known history of PONV received a standard dose of 4 mg of dexamethasone perioperatively. Blood tests were drawn at the first postoperative day and were compared with blood tests of patients who had no history of PONV and therefore received no prophylaxis. Patients who were treated with a dexamethasone PONV prophylaxis showed no significant changes in cortisol levels; preoperative median of 93 μg/L (range, 39 to 427) and a postoperative median of 87 μg/L (range, 10 to 733; P=0.798) opposed to patients who did not receive such treatment; preoperative cortisol 114 μg/L (range, 10 to 387) and postoperative levels of 273 μg/L (range, 10 to 1352; Ptranssphenoidal surgery, the probability that dexamethasone PONV prophylaxis suppresses postoperative cortisol levels should be considered.

    Central nervous system (CNS) involvement with diffuse large B-cell lymphoma (DLBCL) is a relatively uncommon manifestation; with most cases of CNS involvement occuring during relapse after primary therapy. CNS dissemination typically occurs early in the disease course and is most likely present subclinically at the time of diagnosis in many patients who later relapse in the CNS. CNS relapse in these patients is associated with poor outcomes. Based on a CNS relapse rate of 5% in DLBCL and weighing the benefits against the toxicities, universal application of CNS prophylaxis is not justified. The introduction of rituximab has significantly reduced the incidence of CNS relapse in DLBCL. Different studies have employed other agents for CNS prophylaxis, such as intrathecal chemotherapy and high-dose systemic agents with sufficient CNS penetration. If CNS prophylaxis is to be given, it should be preferably administered during primary chemotherapy. However, there is no strong evidence that supports any single approach for CNS prophylaxis. In this review, we outline different strategies of administering CNS prophylaxis in DLBCL patients reported in literature and discuss their advantages and drawbacks. © 2016 John Wiley & Sons A/S.

    Compared with systemic antibiotic therapy, the topical or local delivery of an antibiotic has many potential advantages. However, local antibiotics at the surgical site have received very limited approval in any of the surgical prophylaxis consensus guidelines that we are aware of. A review of the literature was carried out through searches of peer-reviewed publications in PubMed in the English language over a 30 year period between January 1980 and May 2010. Both retrospective and prospective studies were included, as well as meta-analyses. With regard to defining \\'topical\\' or \\'local\\' antibiotic application, the application of an antibiotic solution to the surgical site intraoperatively or immediately post-operatively was included. A number of surgical procedures have been shown to significantly benefit from perioperative topical prophylaxis, e.g. joint arthroplasty, cataract surgery and, possibly, breast augmentation. In obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. The selective use of topical antibiotics as surgical prophylaxis is justified for specific procedures, such as joint arthroplasty, cataract surgery and, possibly, breast augmentation. In selective cases, such as obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. Apart from these specific indications, the evidence for use of topical antibiotics in surgery is lacking in conclusive randomized controlled trials.

    We compared two imipenem regimens for prevention of septic complications in patients with severe acute necrotizing pancreatitis (ANP). Prospective, randomized open clinical trial involving intensive care units of 14 Spanish Hospitals. 92 patients with ANP. Imipenem/cilastatin was administered at 500 mg four times daily starting at the time of diagnosis of ANP, within the first 96 h from the onset of symptoms. Patients were randomized to receive antibiotic prophylaxis either for 14 days (group 1) or at least for 14 days and as long as major systemic complications of the disease persisted (group 2). Antibiotic was maintained in group 2 for 19.7+/-10.9 days. The incidence of infected pancreatic necrosis, pancreatic abscess, and extrapancreatic infections was 11%, 17%, and 28% in group 1 and 17.4%, 13%, and 35% in group 2 (n.s.). Pancreatic or extrapancreatic infection by Candida albicans occurred in 7% and 22% of patients. Global mortality was 18.5% (10.9% secondary to septic complications), without differences between groups. In patients with persisting systemic complications at day 14 mortality was almost always secondary to septic complications and decreased from 25% (group 1) to 8.8% (group 2) by maintaining antibiotic prophylaxis. Compared to a 14-day imipenem prophylaxis, a longer antibiotic administration in patients with ANP is not associated with a reduction in the incidence of septic complications of the disease. However, prolonged imipenem administration in patients with persisting systemic complications tends to reduce mortality in ANP compared to a 14-days regimen.

    To develop a decision model to evaluate the risks, benefits, and costs of different approaches to aspirin prophylaxis for the approximately 4 million pregnant women in the United States annually. We created a decision model to evaluate four approaches to aspirin prophylaxis in the United States: no prophylaxis, prophylaxis per American College of Obstetricians and Gynecologists (the College) recommendations, prophylaxis per U.S. Preventive Services Task Force recommendations, and universal prophylaxis. We included the costs associated with aspirin, preeclampsia, preterm birth, and potential aspirin-associated adverse effects. TreeAge Pro 2011 was used to perform the analysis. The estimated rate of preeclampsia would be 4.18% without prophylaxis compared with 4.17% with the College approach in which 0.35% (n=14,000) of women receive aspirin, 3.83% with the U.S. Preventive Services Task Force approach in which 23.5% (n=940,800) receive aspirin, and 3.81% with universal prophylaxis. Compared with no prophylaxis, the U.S. Preventive Services Task Force approach would save $377.4 million in direct medical care costs annually, and universal prophylaxis would save $365 million assuming 4 million births each year. The U.S. Preventive Services Task Force approach is the most cost-beneficial in 79% of probabilistic simulations. Assuming a willingness to pay of $100,000 per neonatal quality-adjusted life-year gained, the universal approach is the most cost-effective in more than 99% of simulations. Both the U.S. Preventive Services Task Force approach and universal prophylaxis would reduce morbidity, save lives, and lower health care costs in the United States to a much greater degree than the approach currently recommended by the College.

    Bacterial infections are a major cause of morbidity and mortality in patients who are neutropenic following chemotherapy for malignancy. Trials have shown the efficacy of antibiotic prophylaxis in reducing the incidence of bacterial infections but not in reducing mortality rates. Our systematic review from 2006 also showed a reduction in mortality. This updated review aimed to evaluate whether there is still a benefit of reduction in mortality when compared to placebo or no intervention. We searched the Cochrane Cancer Network Register of Trials (2011), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2011), MEDLINE (1966 to March 2011), EMBASE (1980 to March 2011), abstracts of conference proceedings and the references of identified studies. Randomised controlled trials (RCTs) or quasi-RCTs comparing different types of antibiotic prophylaxis with placebo or no intervention, or another antibiotic, to prevent bacterial infections in afebrile neutropenic patients. Two authors independently appraised the quality of each trial and extracted data from the included trials. Analyses were performed using RevMan 5.1 software. One-hundred and nine trials (involving 13,579 patients) that were conducted between the years 1973 to 2010 met the inclusion criteria. When compared with placebo or no intervention, antibiotic prophylaxis significantly reduced the risk of death from all causes (46 trials, 5635 participants; risk ratio (RR) 0.66, 95% CI 0.55 to 0.79) and the risk of infection-related death (43 trials, 5777 participants; RR 0.61, 95% CI 0.48 to 0.77). The estimated number needed to treat (NNT) to prevent one death was 34 (all-cause mortality) and 48 (infection-related mortality).Prophylaxis also significantly reduced the occurrence of fever (54 trials, 6658 participants; RR 0.80, 95% CI 0.74 to 0.87), clinically documented infection (48 trials, 5758 participants; RR 0.65, 95% CI 0.56 to 0.76), microbiologically documented infection

    Heart valve repair or replacement is a serious problem. Patients can benefit from an open dialogue between both cardiologists and gastroenterologists for the optimal effective patients care. The focused update on infective endocarditis of the American College of Cardiology/American Heart Association 2008 (ACC/AHA guidelines) and guidelines on the prevention, diagnosis, and treatment of infective endocarditis (new version 2009) of the European Society of Cardiology (ESC guidelines) describe prophylaxis against infective endocarditis (IE) as not recommended for gastroscopy and colonoscopy in the absence of active infection but increasing evidence suggests that the role of IE antibiotic prophylaxis remains a dark side of the cardio-oncology prevention. New evidences concerning infective endocarditis due to Streptococcus bovis, Streptococcus agalactiae, Enterococcus faecalis, Enterococcus faecium, Enterococcus durans, and new findings indicate that there is a need for bacterial endocarditis prophylaxis in patients undergoing gastrointestinal endoscopy especially in elderly patients and in cancer and immunocompromised patients, to avoid serious consequences.

    2018-05-14

    The role of oral antibiotic prophylaxis and mechanical bowel preparation in colorectal surgery remains controversial. The lack of efficacy of mechanical preparation to improve infection rates, its adverse effects, and multimodal rehabilitation programs have led to a decline in its use. This review aims to evaluate current evidence on antegrade colonic cleansing combined with oral antibiotics for the prevention of surgical site infections. In experimental studies, oral antibiotics decrease the bacterial inoculum, both in the bowel lumen and surgical field. Clinical studies have shown a reduction in infection rates when oral antibiotic prophylaxis is combined with mechanical preparation. Oral antibiotics alone seem to be effective in reducing infection in observational studies, but their effect is inferior to the combined preparation. In conclusion, the combination of oral antibiotics and mechanical preparation should be considered the gold standard for the prophylaxis of postoperative infections in colorectal surgery.

    Numerous techniques are used to prevent infection after immediate implant-based breast reconstruction. Postoperative antibiotic prophylaxis is commonly prescribed to decrease the risk of reconstructive failure, despite conflicting evidence regarding its effectiveness. The authors studied whether postoperative antibiotic prophylaxis decreases the risk of infection-related explantation in the setting of immediate prosthesis-based breast reconstruction. Using Truven MarketScan databases, the authors identified all patients who underwent immediate implant reconstruction between January of 2010 and June of 2014 with at least 6 months of follow-up. Postoperative antibiotic prophylaxis was defined as any oral antibiotic course to be taken postoperatively based on prescriptions filled within 14 days preoperatively through 24 hours after discharge. Reconstructive failure, defined as explantation because of infection, was the primary outcome. Secondary outcomes of interest included wound complications, infection, and readmission for infection. Multivariable regression analyses controlled for demographic variables/comorbidities. Of the 7443 patients, 6049 (81 percent) filled prescriptions for postoperative antibiotic prophylaxis. These patients were equally likely to develop a wound complication (OR, 0.93; 95 percent CI, 0.71 to 1.23) or infection (OR, 0.89; 95 percent CI, 0.70 to 1.14), undergo explantation because of infection (OR, 0.82; 95 percent CI, 0.57 to 1.18), or require readmission for infection (OR, 1.21; 95 percent CI, 0.82 to 1.78) compared with those who did not receive antibiotics. There was no significant difference in the risk of infection-related outcomes based on postoperative antibiotic prophylaxis duration. Postoperative antibiotic prophylaxis was not associated with a reduced risk of infection or explantation following prosthesis-based breast reconstruction. Given rising rates of antibiotic resistance, focusing instead on technical considerations and the

    Background Despite safe and cost-effective venous thromboembolism (VTE) prevention measures, VTE prophylaxis rates are often suboptimal. Healthcare reform efforts emphasize transparency through programs to report performance, and payment incentives through programs to pay-for-performance. Objective To sequentially examine an individualized physician dashboard and pay-for-performance program to improve VTE prophylaxis rates amongst hospitalists. Design Retrospective analysis of 3144 inpatient admissions. After a baseline observation period, VTE prophylaxis compliance was compared during both interventions. Setting 1060-bed tertiary care medical center. Participants 38 part- and full-time academic hospitalists. Interventions A Web-based hospitalist dashboard provided VTE prophylaxis feedback. After 6 months of feedback only, a pay-for-performance program was incorporated, with graduated payouts for compliance rates of 80-100%. Measurements Prescription of American College of Chest Physicians guideline-compliant VTE prophylaxis and subsequent pay-for-performance payments. Results Monthly VTE prophylaxis compliance rates were 86% (95% CI: 85, 88), 90% (95% CI: 88, 93), and 94% (95% CI: 93, 96) during the baseline, dashboard, and combined dashboard/pay-for-performance periods, respectively. Compliance significantly improved with the use of the dashboard (p=0.01) and addition of the pay-for-performance program (p=0.01). The highest rate of improvement occurred with the dashboard (1.58%/month; p=0.01). Annual individual physician performance payments ranged from $53 to $1244 (mean $633; SD ±350). Conclusions Direct feedback using dashboards was associated with significantly improved compliance, with further improvement after incorporating an individual physician pay-for-performance program. Real-time dashboards and physician-level incentives may assist hospitals in achieving higher safety and quality benchmarks. PMID:25545690

    Effective strategies are urgently needed to reduce mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) through breast-feeding in resource-limited settings. Women with HIV-1 infection who were breast-feeding infants were enrolled in a randomized, phase 3 trial in Blantyre, Malawi. At birth, the infants were randomly assigned to one of three regimens: single-dose nevirapine plus 1 week of zidovudine (control regimen) or the control regimen plus daily extended prophylaxis either with nevirapine (extended nevirapine) or with nevirapine plus zidovudine (extended dual prophylaxis) until the age of 14 weeks. Using Kaplan-Meier analyses, we assessed the risk of HIV-1 infection among infants who were HIV-1-negative on DNA polymerase-chain-reaction assay at birth. Among 3016 infants in the study, the control group had consistently higher rates of HIV-1 infection from the age of 6 weeks through 18 months. At 9 months, the estimated rate of HIV-1 infection (the primary end point) was 10.6% in the control group, as compared with 5.2% in the extended-nevirapine group (P<0.001) and 6.4% in the extended-dual-prophylaxis group (P=0.002). There were no significant differences between the two extended-prophylaxis groups. The frequency of breast-feeding did not differ significantly among the study groups. Infants receiving extended dual prophylaxis had a significant increase in the number of adverse events (primarily neutropenia) that were deemed to be possibly related to a study drug. Extended prophylaxis with nevirapine or with nevirapine and zidovudine for the first 14 weeks of life significantly reduced postnatal HIV-1 infection in 9-month-old infants.

    Guidelines for antibiotics prior to dental procedures for patients with specific cardiac conditions and prosthetic joints have changed, reducing indications for antibiotic prophylaxis. In addition to guidelines focused on patient comorbidities, systematic reviews specific to dental extractions and implants support preprocedure antibiotics for all patients. However, data on dentist adherence to these recommendations are scarce. This was a cross-sectional study of veterans undergoing tooth extractions, dental implants, and periodontal procedures. Patients receiving antibiotics for oral or nonoral infections were excluded. Data were collected through manual review of the health record. Of 183 veterans (mean age, 62 years; 94.5% male) undergoing the included procedures, 82.5% received antibiotic prophylaxis (mean duration, 7.1 ± 1.6 days). Amoxicillin (71.3% of antibiotics) and clindamycin (23.8%) were prescribed most frequently; 44.7% of patients prescribed clindamycin were not labeled as penicillin allergic. Of those who received prophylaxis, 92.1% received postprocedure antibiotics only, 2.6% received preprocedural antibiotics only, and 5.3% received pre- and postprocedure antibiotics. When prophylaxis was indicated, 87.3% of patients received an antibiotic. However, 84.9% received postprocedure antibiotics when preprocedure administration was indicated. While the majority of antibiotics were indicated, only 8.2% of patients received antibiotics appropriately. The primary reason was secondary to prolonged duration. Three months postprocedure, there were no occurrences of Clostridium difficile infection, infective endocarditis, prosthetic joint infections, or postprocedure oral infections. The majority of patients undergoing a dental procedure received antibiotic prophylaxis as indicated. Although patients for whom antibiotic prophylaxis was indicated should have received a single preprocedure dose, most antibiotics were prescribed postprocedure. Dental stewardship

Materials and methods: Patients affected by UTIr older than 18 years started a 3-months antibiotic prophylaxis (Prulifloxacin 600 mg, 1 cps/week or Phosphomicyn 1 cachet/week according to antibiogram after urine culture. The patients were divided in 2 groups: Group A: antibiotic prophylaxis plus phytotherapy (1 cps/die for 3 months and Group B: antibiotic prophylaxis alone. Results: 164 consecutive patients were studied: 107 were included in group A (mean age 59 ± 17.3 years and 57 (mean age 61 ± 15.7 in group B. During the treatment period the relapse frequencies between the two groups were not significantly different (p = 0.854: 12/107 (11.21% patients interrupted the treatment for UTIr in group A and 6/57 (10.52% in group B. In the long term follow-up the relapse UTI risk was significant different in the two groups with a relapse risk 2.5 greater in group B than in group A (p < 0.0001. Conclusion: Our study demonstrated that in female patients affected by recurrent UTI, the association between antibiotic prophylaxis and of a phytotherapic which includes Solidago, Orthosiphon and Birch extract reduced the number of UTI in the 12 months following the end of prophylaxis and obtained a longer relapsing time, greatly improving the quality of life of the patients.

    Indomethacin prophylaxis or expectant treatment are common strategies for the prevention or management of symptomatic patent ductus arteriosus (sPDA). To compare the clinical responses of extremely low birth weight (ELBW) infants to indomethacin prophylaxis with that of other infants who were managed expectantly by being treated with indomethacin or surgically only after an sPDA was detected. Retrospective cohort investigation of 167 ELBW infants who received indomethacin prophylaxis (study) and 167 ELBW infants (control) treated expectantly who were matched by year of birth (1999 to 2006), birth weight, gestational age (GA) and gender. Mothers of the two groups of infants were comparable demographically and on the history of preterm labor, pre-eclampsia, antepartum steroids and cesarean delivery. Study and control infants were similar in birth weight, GA, low 5 min Apgar scores, surfactant administration, the need for arterial blood pressure control, bronchopulmonary dysplasia and neonatal mortality. Necrotizing enterocolitis, spontaneous intestinal perforations, intraventricular hemorrhage grade III to IV, periventricular leukomalacia and stage 3 to 5 retinopathy of prematurity occurred also with similar frequency in both groups of infants. In the indomethacin prophylaxis group, 29% of the infants developed sPDA, and of them 38% responded to indomethacin treatment. In the expectantly treated group, 37% developed sPDA, and of them 59% responded to indomethacin treatment. Overall, surgical ligation rate for sPDA was similar between both groups of patients. In our experience, indomethacin prophylaxis does not show any advantages over expectant early treatment on the management of sPDA in ELBW infants. Although no deleterious effects were observed, prophylaxis exposed a significant number of infants who may have never developed sPDA, to potential indomethacin-related complications.

Individuals who undergo transplantation must chronically be maintained on an immunosuppression regimen for rejection prophylaxis to help ensure graft survival. Current rejection prophylaxis consists of using a combination of calcineurin inhibitors, mTOR inhibitors, antimetabolite agents, and/or corticosteroids. These agents have collectively improved the short-term outcomes of renal transplantation, but improvements in late/chronic graft loss and recipient survival have lagged significantly behind challenging the field of transplantation to develop novel prophylactic agents. There have been several clinical trials conducted within the last 5 years in an attempt to bring such novel agents to the commercial market. These trials have resulted in the US Food and Drug Administration (FDA approval of extended-release tacrolimus, as well as belatacept, which has the potential to replace calcineurin inhibitors for rejection prophylaxis. Other trials have focused on the development of novel calcineurin inhibitors (voclosporin, costimulation blockade (ASKP1240 and alefacept, kinase inhibitors (tofacitinib and sotrastaurin, and inhibitors of leukocyte migration (efalizumab. While these later agents have not been FDA-approved for use in transplantation, they remain noteworthy, as these agents explore pathways not previously targeted for allograft-rejection prophylaxis. The purpose of this review was to consolidate available clinical trial data with regard to the recent developments in rejection prophylaxis in kidney transplantation.

    Antibiotic use, particularly type and duration, is a crucial modifiable risk factor for Clostridium difficile. Cardiac surgery is of particular interest because prophylactic antibiotics are recommended for 48 hours or less (vs ≤24 hours for noncardiac surgery), with increasing vancomycin use. We aimed to study associations between antibiotic prophylaxis (duration/vancomycin use) and C difficile among patients undergoing coronary artery bypass grafting. We extracted data on coronary artery bypass grafting procedures from the national Premier Perspective claims database (2006-2013, n = 154,200, 233 hospitals). Multilevel multivariable logistic regressions measured associations between (1) duration (difficile as outcome. Overall C difficile prevalence was 0.21% (n = 329). Most patients (59.7%) received a cephalosporin only; in 33.1% vancomycin was added, whereas 7.2% received vancomycin only. Extended prophylaxis was used in 20.9%. In adjusted analyses, extended prophylaxis (vs standard) was associated with significantly increased C difficile risk (odds ratio, 1.43; confidence interval, 1.07-1.92), whereas no significant associations existed for vancomycin use as adjuvant or primary prophylactic compared with the use of cephalosporins (odds ratio, 1.21; confidence interval, 0.92-1.60, and odds ratio, 1.39; confidence interval, 0.94-2.05, respectively). Substantial inter-hospital variation exists in the percentage of extended antibiotic prophylaxis (interquartile range, 2.5-35.7), use of adjuvant vancomycin (interquartile range, 4.2-61.1), and vancomycin alone (interquartile range, 2.3-10.4). Although extended use of antibiotic prophylaxis was associated with increased C difficile risk after coronary artery bypass grafting, vancomycin use was not. The observed hospital variation in antibiotic prophylaxis practices suggests great potential for efforts aimed at standardizing practices that subsequently could reduce C difficile risk.

    Pre-exposure prophylaxis is a novel biomedical HIV prevention option for individuals at high risk of HIV acquisition. Although pre-exposure prophylaxis has yielded encouraging results in various clinical trials, opponents argue that pre-exposure prophylaxis poses a number of risks to human health and to sexually transmitted infection prevention efforts. Using qualitative thematic analysis and social representation theory, this article explores coverage of pre-exposure prophylaxis in the UK print media between 2008 and 2015 in order to chart the emerging social representations of this novel HIV prevention strategy. The analysis revealed two competing social representations of pre-exposure prophylaxis: (1) as a positive development in the 'battle' against HIV (the hope representation) and (2) as a medical, social and psychological setback in this battle, particularly for gay/bisexual men (the risk representation). These social representations map onto the themes of pre-exposure prophylaxis as a superlatively positive development; pre-exposure prophylaxis as a weapon in the battle against HIV/AIDS; and risk, uncertainty and fear in relation to pre-exposure prophylaxis. The hope representation focuses on taking (individual and collective) responsibility, while the risk representation focuses on attributing (individual and collective) blame. The implications for policy and practice are discussed.

    Full Text Available Background: Wound infection is the most frequent complication in burn patients. There is a lack of guidelines on the use of systemic antibiotics in children to prevent this complication. Patients and Methods: A prospective study is carried out on 80 patients to evaluate the role of antibiotic prophylaxis in the control of infections. Results: The mean age was 34 months (9 months to 8 years. There was a male predominance with sex ratio of 1.66. The mean burn surface size burn was 26.5% with total burn surface area ranging from 5% to 33%, respectively. According to American Burn Association 37% (30/80 were severe burns with second and third degree burns >10% of the total surface body area in children aged <10 years old. Scalds represented 76.2% (61/80 of the burns. Burns by hot oil were 11 cases (13.7%, while 8 cases (10% were flame burns. The random distribution of the groups was as follow: Group A (amoxicilline + clavulanic acid = 25 cases, Group B (oxacilline = 20 cases and Group C (no antibiotics = 35 cases. Total infection rate was 20% (16/80, distributed as follow: 8 cases (50% in Group C, 5 cases (31.2% in Group A and 3 cases in Group B (18.7%. Infection rate in each individual group was: 22.9% (8 cases/35 in Group C, 20% (5 cases/25 in Group A and 15% (3 cases/20 in Group B (P = 0.7. They were distributed as follow: Septicaemia 12 cases/16 (75%, wound infection 4 cases/16 (25%. Bacteria isolated were with a decreasing order: Staphylococcus aureus (36.3%, Pseudomonas (27.2%, Escherichia coli (18.1%, Klebsiella (9% and Enterobacteria (9%. There is a tendency to a delayed cicatrisation (P = 0.07 in case of hot oil burns (65.18 ± 120 days than by flame (54.33 ± 19.8 days than by hot water (29.55 ± 26.2 days. Otherwise no toxic shock syndrome was recorded in this study. Conclusion: It is concluded that adequate and careful nursing of burn wounds seems to be sufficient to prevent complications and to obtain cicatrisation. Antibiotics are

    Full Text Available Although the prophylactic administration of indomethacin in extremely low-birth weight infants reduces the frequency of patent ductus arteriosus and severe intraventricular hemorrhage, it does not appear to provide any long-term benefit in terms of survival without neurosensory and cognitive outcomes. Considering the increased drug-induced reduction in renal, intestinal, and cerebral blood flow, the use of prophylaxis cannot be routinely recommended in preterm neonates. However, a better understanding of the genetic background of each infant may allow for individualized prophylaxis using NSAIDs and metabolomics.

    The World Health Organisation and the Joint United Nations Programme in 2006 reaffirmed the earlier recommendation of 2000 that all HIV-exposed infants in resource-poor countries should commence cotrimoxazole (CTX) prophylaxis at 6-weeks of life. CTX prophylaxis should be continued until the child is confirmed HIV-uninfected and there is no further exposure to breastmilk transmission. We determined CTX coverage and explored factors associated with CTX administration in HIV-exposed infants at a primary health clinic in South Africa. In a cross-sectional study of HIV-exposed infants 6-18 months of age attending a child immunisation clinic, data from the current visit and previous visits related to CTX prophylaxis, feeding practice and infant HIV testing were extracted from the child's immunisation record. Further information related to the administration of CTX prophylaxis was obtained from an interview with the child's mother. One-third (33.0%) HIV-exposed infants had not initiated CTX at all and breastfed infants were more likely to have commenced CTX prophylaxis as compared to their non-breastfed counterparts (78.7% vs 63.4%) (p = 0.008). Availability of infant's HIV status was strongly associated with continuation or discontinuation of CTX after 6 months of age or after breastfeeding cessation. Maternal self-reports indicated that only 52.5% (95%CI 47.5-57.5) understood the reason for CTX prophylaxis, 126 (47%) did not dose during weekends; 55 (21%) dosed their infants 3 times a day and 70 (26%) dosed their infants twice daily. A third of HIV-exposed children attending a primary health care facility in this South African setting did not receive CTX prophylaxis. Not commencing CTX prophylaxis was strongly associated with infants not breastfeeding and unnecessary continued exposure to CTX in this paediatric population was due to limited availability of early infant diagnosis. Attendance at immunization clinics can be seen as missed opportunities for early

    A recent randomized trial demonstrated that 1 year of antiviral prophylaxis for cytomegalovirus (CMV) after lung transplantation is superior to 3 months of treatment for prevention of CMV disease. However, it is uncertain if a shorter duration of prophylaxis might result in a similar rate of CMV disease among select lung transplant (LT) recipients who are at lower risk for CMV disease, based on baseline donor (D) and recipient (R) CMV serologies. We retrospectively assessed incidence, cumulative probability, and predictors of CMV disease and viremia in LT recipients transplanted between July 2004 and December 2009 at our center, where antiviral CMV prophylaxis for 6-12 months is standard. Of 129 LT recipients, 94 were at risk for CMV infection based on donor CMV seropositivity (D+) or recipient seropositivity (R+); 14 developed CMV disease (14.9%): 11 with CMV syndrome, 2 with pneumonitis, and 1 with gastrointestinal disease by the end of follow-up (October 2010); 17 developed asymptomatic CMV viremia (18.1%). The cumulative probability of CMV disease was 17.4% 18 months after transplantation. CMV D+/R- recipients who routinely received 1 year of prophylaxis were more likely to develop CMV disease compared with D+/R+ or D-/R+ recipients, who routinely received 6 months of prophylaxis (12/45 vs. 2/25 vs. 0/24, P = 0.005). Recipients who stopped CMV prophylaxis before 12 months (in D+/R- recipients) and 6 months (in R+ recipients) tended to develop CMV disease more than those who did not (9/39 vs. 3/41, P = 0.06). On a 6-month CMV prophylaxis protocol, few R+ recipients developed CMV disease in this cohort. In contrast, despite a 12-month prophylaxis protocol, D+/R- LT recipients remained at highest risk for CMV disease. © 2012 John Wiley & Sons A/S.

    Surgical site infections are the most common hospital-acquired infections among surgical patients. The administration of surgical antimicrobial prophylaxis reduces the risk of surgical site infections . The optimal timing of this procedure is still a matter of debate. While most studies suggest that it should be given as close to the incision time as possible, others conclude that this may be too late for optimal prevention of surgical site infections. A large observational study suggests that surgical antimicrobial prophylaxis should be administered 74 to 30 minutes before surgery. The aim of this article is to report the design and protocol of a randomized controlled trial investigating the optimal timing of surgical antimicrobial prophylaxis. In this bi-center randomized controlled trial conducted at two tertiary referral centers in Switzerland, we plan to include 5,000 patients undergoing general, oncologic, vascular and orthopedic trauma procedures. Patients are randomized in a 1:1 ratio into two groups: one receiving surgical antimicrobial prophylaxis in the anesthesia room (75 to 30 minutes before incision) and the other receiving surgical antimicrobial prophylaxis in the operating room (less than 30 minutes before incision). We expect a significantly lower rate of surgical site infections with surgical antimicrobial prophylaxis administered more than 30 minutes before the scheduled incision. The primary outcome is the occurrence of surgical site infections during a 30-day follow-up period (one year with an implant in place). When assuming a 5% surgical site infection risk with administration of surgical antimicrobial prophylaxis in the operating room, the planned sample size has an 80% power to detect a relative risk reduction for surgical site infections of 33% when administering surgical antimicrobial prophylaxis in the anesthesia room (with a two-sided type I error of 5%). We expect the study to be completed within three years. The results of this

    Full Text Available The effect of professional dental prophylaxis with sodium bicarbonate jet on salivary counting of mutans streptococci and lactobacilli in 32 children ranging from 7 to 10 years of age, has been assessed. Whole stimulated saliva was collected before the prophylaxis, immediately after it and 30 days later, and the number of CFU/ml in the saliva was detected through the Caritest system. A statistically significant immediate decrease on salivary levels of both microorganisms was observed, 50% for mutans streptococci and 27% for lactobacilli. For mutans streptococci this decrease continued through the 30 days period; the same did not occur with lactobacilli, that returned to their baseline values.

    The additional value of perioperative antibiotic prophylaxis in preventing infectious complications after emergency cholecystectomy for acute cholecystitis is a much-debated subject in the surgical community. Evidence-based guidelines are lacking, and consequently the use of antibiotic prophylaxis varies greatly among surgeons and hospitals. Recently, high-level evidence became available demonstrating that postoperative antibiotic prophylaxis in patients with acute cholecystitis does not reduce the risk of infectious complications. Preoperative antibiotic prophylaxis in relation to the risk of infectious complications, however, has never been studied. The PEANUTS II trial is a randomized, controlled, multicenter, open-label noninferiority trial whose aim is to determine the utility of preoperative antibiotic prophylaxis in patients undergoing emergency cholecystectomy for acute calculous cholecystitis. Patients with mild or moderate acute cholecystitis, as defined according the Tokyo Guidelines, will be randomly assigned to a single preoperative dose of antibiotic prophylaxis (2000 mg of first-generation cephalosporin delivered intravenously) or no antibiotic prophylaxis before emergency cholecystectomy. The primary endpoint is a composite endpoint consisting of all postoperative infectious complications occurring during the first 30 days after surgery. Secondary endpoints include all the individual components of the primary endpoint, all other complications, duration of hospital stay, and total costs. The hypothesis is that the absence of antibiotic prophylaxis is noninferior to the presence of antibiotic prophylaxis. A noninferiority margin of 10% is assumed. With a 1-sided risk of 2.5% and a power of 80%, a total of 454 subjects will have to be included. Analysis will be performed according to the intention-to-treat principle. The PEANUTS II trial will provide evidence-based advice concerning the utility of antibiotic prophylaxis in patients undergoing

    In sub-Saharan Africa, among patients with advanced human immunodeficiency virus (HIV) infection, the rate of death from infection (including tuberculosis and cryptococcus) shortly after the initiation of antiretroviral therapy (ART) is approximately 10%. In this factorial open-label trial conducted in Uganda, Zimbabwe, Malawi, and Kenya, we enrolled HIV-infected adults and children 5 years of age or older who had not received previous ART and were starting ART with a CD4+ count of fewer than 100 cells per cubic millimeter. They underwent simultaneous randomization to receive enhanced antimicrobial prophylaxis or standard prophylaxis, adjunctive raltegravir or no raltegravir, and supplementary food or no supplementary food. Here, we report on the effects of enhanced antimicrobial prophylaxis, which consisted of continuous trimethoprim-sulfamethoxazole plus at least 12 weeks of isoniazid-pyridoxine (coformulated with trimethoprim-sulfamethoxazole in a single fixed-dose combination tablet), 12 weeks of fluconazole, 5 days of azithromycin, and a single dose of albendazole, as compared with standard prophylaxis (trimethoprim-sulfamethoxazole alone). The primary end point was 24-week mortality. A total of 1805 patients (1733 adults and 72 children or adolescents) underwent randomization to receive either enhanced prophylaxis (906 patients) or standard prophylaxis (899 patients) and were followed for 48 weeks (loss to follow-up, 3.1%). The median baseline CD4+ count was 37 cells per cubic millimeter, but 854 patients (47.3%) were asymptomatic or mildly symptomatic. In the Kaplan-Meier analysis at 24 weeks, the rate of death with enhanced prophylaxis was lower than that with standard prophylaxis (80 patients [8.9% vs. 108 [12.2%]; hazard ratio, 0.73; 95% confidence interval [CI], 0.55 to 0.98; P=0.03); 98 patients (11.0%) and 127 (14.4%), respectively, had died by 48 weeks (hazard ratio, 0.76; 95% CI, 0.58 to 0.99; P=0.04).

    Venous thromboembolism (VTE) remains a common problem in critically ill patients. Pharmacologic prophylaxis is currently the standard of care based on high-level evidence from randomized controlled trials. However, limited evidence exists regarding the effectiveness of intermittent pneumatic compression (IPC) devices. The Pneumatic compREssion for preventing VENous Thromboembolism (PREVENT trial) aims to determine whether the adjunct use of IPC with pharmacologic prophylaxis compared to pharmacologic prophylaxis alone in critically ill patients reduces the risk of VTE. The PREVENT trial is a multicenter randomized controlled trial, which will recruit 2000 critically ill patients from over 20 hospitals in three countries. The primary outcome is the incidence of proximal lower extremity deep vein thrombosis (DVT) within 28 days after randomization. Radiologists interpreting the scans are blinded to intervention allocation, whereas the patients and caregivers are unblinded. The trial has 80 % power to detect a 3 % absolute risk reduction in proximal DVT from 7 to 4 %. The first patient was enrolled in July 2014. As of May 2015, a total of 650 patients have been enrolled from 13 centers in Saudi Arabia, Canada and Australia. The first interim analysis is anticipated in July 2016. We expect to complete recruitment by 2018. Clinicaltrials.gov: NCT02040103 (registered on 3 November 2013). Current controlled trials: ISRCTN44653506 (registered on 30 October 2013).

    Viruses detected in patients with acute respiratory infections may be the cause of illness or asymptomatic shedding. To estimate the attributable fraction (AF) and the detection rate attributable to illness for each of the different respiratory viruses We compared the prevalence of 10 common respiratory viruses (influenza A and B viruses, parainfluenza virus 1-3; respiratory syncytial virus (RSV); adenovirus, rhinovirus, human metapneumovirus (hMPV) and enterovirus) in both HIV positive and negative patients hospitalized with severe acute respiratory illness (SARI), outpatients with influenza-like illness (ILI), and control subjects who did not report any febrile, respiratory or gastrointestinal illness during 2012-2015 in South Africa. We enrolled 1959 SARI, 3784 ILI and 1793 controls with a HIV sero-prevalence of 26%, 30% and 43%, respectively. Influenza virus (AF: 86.3%; 95%CI: 77.7-91.6%), hMPV (AF: 85.6%; 95%CI: 72.0-92.6%), and RSV (AF: 83.7%; 95%CI: 77.5-88.2%) infections were associated with severe disease., while rhinovirus (AF: 46.9%; 95%CI: 37.6-56.5%) and adenovirus (AF: 36.4%; 95%CI: 20.6-49.0%) were only moderately associated. Influenza, RSV and hMPV can be considered pathogens if detected in ILI and SARI while rhinovirus and adenovirus were commonly identified in controls suggesting that they may cause only a proportion of clinical disease observed in positive patients. Nonetheless, they may be important contributors to disease. Copyright © 2015 Elsevier B.V. All rights reserved.

  19. Cultural conundrums: the ethics of epidemiology and the problems of population in implementing pre-exposure prophylaxis.

    Science.gov (United States)

    Fiereck, Kirk

    2015-04-01

    The impending implementation of pre-exposure prophylaxis (PrEP) has prompted complicated bioethical and public health ethics concerns regarding the moral distribution of antiretroviral medications (ARVs) to ostensibly healthy populations as a form of HIV prevention when millions of HIV-positive people still lack access to ARVs globally. This manuscript argues that these questions are, in part, concerns over the ethics of the knowledge production practices of epidemiology. Questions of distribution, and their attendant cost-benefit calculations, will rely on a number of presupposed, and therefore, normatively cultural assumptions within the science of epidemiology specifically regarding the ability of epidemiologic surveillance to produce accurate maps of HIV throughout national populations. Specifically, ethical questions around PrEP will focus on who should receive ARVs given the fact that global demand will far exceed supply. Given that sexual transmission is one of the main modes of HIV transmission, these questions of 'who' are inextricably linked to knowledge about sexual personhood. As a result, the ethics of epidemiology, and how the epidemiology of HIV in particular conceives, classifies and constructs sexual populations will become a critical point of reflection and contestation for bioethicists, health activists, physicians, nurses, and researchers in the multi-disciplinary field of global health. This paper examines how cultural conundrums within the fields of bioethics and public health ethics are directly implicated within the ethics of PrEP, by analyzing the problems of population inaugurated by the construction of the men who have sex with men (MSM) epidemiologic category in the specific national context of South Africa. © 2013 John Wiley & Sons Ltd.

    The relative performance of 2 widely used reverse transcription polymerase chain reaction (RT-PCR) assays, the Focus diagnostics Simplexa™ Flu A/B & RSV kit (nucleic acid extraction-dependent assay) and the Prodessa Proflu+™ assay, was evaluated using 735 prospectively and retrospectively collected nasopharyngeal swab specimens. Overall, the assays showed positive and negative agreements of 100% and 99.7% for influenza A, 98.1% and 99.9% for influenza B, and 99.3% and 99.5% for respiratory syncytial virus. The relative analytical sensitivity of the 2 assays was also similar. Copyright © 2014 Elsevier Inc. All rights reserved.

    Severe congenital factor VII (FVII) deficiency is a rare bleeding disorder. Prophylaxis with replacement therapy has been suggested to patients, yet the most beneficial dosing regimens and therapy intervals are still to be defined. Due to the lack of evidence-based data, we hereby present our experience with long-term administration and monitoring primary prophylaxis in children with severe FVII deficiency and an extremely high bleeding risk. Four children with familial FVII deficiency, treated by prophylactic recombinant activated factor VII (rFVIIa), 15-30μg/kg/dose, given 2-3 times weekly since infancy, are discussed. Clinical follow up and monitoring laboratory assays, including thrombin generation, measured at various time points after prophylactic rFVIIa administration are presented. Among our treated patients neither FVII activity nor thrombin generation parameters (both already declined 24h post rFVIIa administration) were able to predict the impact of prophylaxis, and could not be used as surrogate markers in order to assess the most beneficial treatment frequency. However, the long clinical follow-up and comprehensive laboratory assessment performed, have shown that early primary prophylaxis as administered in our cohort was safe and effective.

    Bacterial and fungal infections in pediatric oncology patients cause morbidity and mortality. The clinical utility of antimicrobial prophylaxis in children is uncertain and the personal utility of these agents is disputed. Objectives were to use a discrete choice experiment to: (1) describe the importance of attributes to parents and healthcare providers when deciding between use and non-use of antibacterial and antifungal prophylaxis; and (2) estimate willingness-to-pay for prophylactic strategies. Attributes were chances of infection, death and side effects, route of administration and cost of pharmacotherapy. Respondents were randomized to a discrete choice experiment outlining hypothetical treatment options to prevent antibacterial or antifungal infections. Each respondent was presented 16 choice tasks and was asked to choose between two unlabeled treatment options and an opt-out alternative (no prophylaxis). 102 parents and 60 healthcare providers participated. For the antibacterial discrete choice experiment, frequency of administration was significantly associated with utility for parents but not for healthcare providers. Increasing chances of infection, death, side effects and cost were all significantly associated with decreased utility for parents and healthcare providers in both the antibacterial and antifungal discrete choice experiment. Parental willingness-to-pay was higher than healthcare providers for both strategies. Chances of infection, death, side effects and costs were all significantly associated with utility. Parents have higher willingness-to-pay for these strategies compared with healthcare providers. This knowledge can help to develop prophylaxis programs.

    2007-08-01

    Full Text Available Prevention of ophthalmia neonatorum (ON in the delivery room has been recommended by the Iranian Ministry of Health and Medical Education only if the mother is affected by STDs. This study aimed at finding out whether the neonatal wards should do prophylaxis as recommended or it is necessary to revise the previously-related protocols. In a randomized clinical trial, 130 full-term neonates born vaginally were selected on simple method in a period of three months and were divided randomly into control and case groups in such a way to be compatible regarding weight, gestational age, and sex. After obtaining parents' permission, 0.5% erythromycin ointment was used for ON prophylaxis. All the newborns were then examined regarding the presence of conjunctivitis during the third and the tenth day of life. The results showed that totally 8 newborns were affected with conjunctivitis, 7 of whom (87.5% belonged to the control group and 1 to the case group (12.5%. However, this difference was not significant. This finding might be due to the inadequate frequency of affected subjects in comparison to the whole subjects under study. Considering other studies showing significant effect of drugs used in ON prophylaxis (silver nitrate, tetracycline, erythromycin, povidone-iodine and based on the results of this study, it is highly recommended that neonatal wards of hospitals in our country carry out prophylaxis of ON in all subjects.

  8. Use of anticonvulsants as prophylaxis for seizures in patients on clozapine.

    Caetano, Dorgival

    2014-02-01

    The aim of this study is to conduct a critical review of the literature regarding the use of anticonvulsants in the prophylaxis of clozapine-induced seizures, to examine the relationship of the latter with clozapine daily dose, serum concentration and other factors than dosage that effect clozapine blood concentration, and to make recommendations for the management of clozapine-induced seizures. A systematic review of English-language MEDLINE articles was undertaken. Clozapine-induced seizures may occur at any dose; the risk increases with dose and goes up to 4% at ≥ 600 mg/day. Some authors have advocated that patients on that dose regimen have anticonvulsant added as a primary prophylactic measure. The author discusses the pitfalls of this recommendation and highlights that seizures are better predicted from serum concentration (1300 ng/ml) rather than dose alone, and that serum concentration is strongly influenced by sex, age, smoking habit, drug-drug interactions and variations in the 1A2, 2D6 and 3A4 genotypes. Anticonvulsants are not recommended as a primary prophylaxis for clozapine-induced seizures. When deemed necessary as secondary prophylaxis, the clinician's choice should consider drug-drug interactions that may increase/decrease clozapine serum concentration and lead to more side effects, including neutropenia/agranulocytosis and seizures, or compromise therapeutic response. Recommendations for primary and secondary prophylaxis of clozapine related-seizures are provided.

  10. Improving venous thromboembolic disease prophylaxis in medical inpatients: a role for education and audit.

    LENUS (Irish Health Repository)

    Kent, B D

    2012-02-01

    BACKGROUND: Venous thromboembolic disease (VTED) prophylaxis is a key strategy in reducing preventable deaths in medical inpatients. We assessed compliance with internationally published guidelines for VTED prophylaxis in at-risk medical patients before and 1 month after an educational intervention to enhance compliance with such guidelines. RESULTS: One hundred and fifty patients were assessed on each occasion. Pre-intervention, VTED prophylaxis was prescribed in only 48% of at-risk cases. Compliance was best among patients under stroke services and worst for those under acute medical teams. Patients within specialist units were more likely to be prescribed prophylaxis than those in general wards (75 vs. 53%; p = 0.0019). Post-intervention, overall compliance improved to 63% (p = 0.041 for comparison). There was a significant improvement among general medical teams (48 vs. 75%; p = 0.001), and in general wards (52 vs. 74%; p = 0.003). CONCLUSIONS: Thromboprophylaxis is under-prescribed in medical inpatients, but compliance with international guidelines can be significantly enhanced with targeted educational intervention.

    Piotrowski, Damian; Boroń-Kaczmarska, Anna

    2017-09-01

    Infections are common among patients with liver cirrhosis. They occur more often in cirrhotic patient groups than in the general population and result in higher mortality. One reason for this phenomenon is bacterial translocation from the intestinal lumen that occurs as a consequence of intestinal bacterial overgrowth, increased permeability and decreased motility. The most common infections in cirrhotic patients are spontaneous bacterial peritonitis and urinary tract infections, followed by pneumonia, skin and soft tissue infections. Intestinal bacterial overgrowth is also responsible for hyperammonemia, which leads to hepatic encephalopathy. All of these complications make this group of patients at high risk for mortality. The role of antibiotics in liver cirrhosis is to treat and in some cases to prevent the development of infectious complications. Based on our current knowledge, antibiotic prophylaxis should be administered to patients with gastrointestinal hemorrhage, low ascitic fluid protein concentration combined with liver or renal failure, and spontaneous bacterial peritonitis as a secondary prophylaxis, as well as after hepatic encephalopathy episodes (also as a secondary prophylaxis). In some cases, the use of non-antibiotic prophylaxis can also be considered. Current knowledge of the treatment of infections allows the choice of a preferred antibiotic for empiric therapy depending on the infection location and whether the source of the disease is nosocomial or community-acquired.

    We concluded that stress ulcer prophylaxis with ranitidine increases the risk for late- onset pneumonia in mechanically ventilated critically ill patients by favoring gastric colonization by gram- negative bacilli compared with sucralfate. In patients receiving mechanical ventilation, the use of sucralfate may be preferable to H 2 blockers.

    2009-03-15

    The key elements required for the health-system pharmacist to prepare and implement a hospital-based mass prophylaxis distribution effort for hospital employees are described. A bioterrorist attack may involve multiple jurisdictions which would necessitate a regional response. Pharmacists should collaborate not only with colleagues in their immediate areas, but also with pharmacists and emergency-management planners in neighboring counties and jurisdictions. Pharmacists must also develop antibiotic drug selection protocols and define the quantity needed to maintain hospital operations after a bioterrorist attack. Once the desired antibiotics have been selected and the number of employees has been determined, along with the length of prophylaxis therapy, it should be determined how much money will be needed to purchase and store enough medications to meet the need. Next, provisions must be made to acquire and store the antibiotic cache, with attention paid to cache rotation and packaging and repackaging recommendations. A detailed procedure for the deployment of an antibiotic cache must be developed. This procedure should include job descriptions and job action sheets for deployment team members and plans for receiving and dispensing antibiotics from the Strategic National Stockpile. Once the employee prophylaxis procedure is developed, staff must be educated about it, and exercises should be conducted to identify possible weaknesses in the procedure. Health-system pharmacists should play an active role in designing and implementing an antibiotic prophylaxis plan for employees for a potential bioterrorist attack. Understanding and following procedures provided in the tool kit are critical to their successful readiness.

  19. Oral Iron Prophylaxis in Pregnancy: Not Too Little and Not Too Much!

    Directory of Open Access Journals (Sweden)

    Nils Milman

    2012-01-01

    Full Text Available An adequate supply of iron is essential for normal development of the fetus and newborn child. Iron deficiency and iron deficiency anemia (IDA during pregnancy increase the risk of preterm birth and low birth weight. Iron is important for development of the fetal brain and cognitive abilities of the newborn. Children born to iron-deficient mothers will start their lives suffering from iron deficiency or even IDA. Oral iron prophylaxis to pregnant women improves iron status and prevents development of IDA. The Danish National Board of Health has since 1992 recommended prophylactic oral iron supplements to all pregnant women and the currently advocated dose is 40–50 mg ferrous iron taken between meals from 10 weeks gestation to delivery. However, 30–40 mg ferrous iron is probably an adequate dose in most affluent societies. In developed countries, individual iron prophylaxis guided by iron status (serum ferritin has physiological advantages compared to general iron prophylaxis. In contrast, in most developing countries, general iron prophylaxis is indicated, and higher doses of oral iron, for example, 60 mg ferrous iron or even more should be recommended, according to the present iron status situation in the specific populations of women of fertile age and pregnant women.

    Miller, Hayleigh; Wheeler, Benjamin; Kerruish, Nikki

    2016-12-02

    Vitamin K prophylaxis represents one of the first healthcare decisions families make for their newborn. Information resources are an important component of this process. This study aimed to identify and analyse written information about vitamin K. Resources concerning vitamin K prophylaxis for both parents and health professionals were accessed through tertiary hospitals in New Zealand and Australia, midwives associated with Queen Mary Maternity Centre (Dunedin, New Zealand), antenatal class providers in the Dunedin, New Zealand area, and an online search of Australian and New Zealand government and hospital websites, as well as the Centre for Disease Control (CDC) in the US. These materials were assessed with regard to coverage of information relevant to vitamin K prophylaxis, whether a statement of the recommended option was included, and information concerning parental choice. In Australia, the majority of centres use the Australian Government National Health and Medical Research Council (NHMRC) resource. In New Zealand, eight different resources are in use. There was variation between resources in all aspects, including use of different incidence rates for vitamin K deficiency bleeding (VKDB). No New Zealand resources were available in languages other than English. The resources for health professionals also varied, and the two available New Zealand consensus statements (Ministry of Health and College of Midwives) differed in terms of their main recommendation. Many different information resources are available regarding vitamin K prophylaxis in New Zealand. Standardisation of such information would be more equitable and would facilitate easier review of content and translation into multiple languages.

  2. Microleakage assessment of fissure sealant following fissurotomy bur or pumice prophylaxis use before etching

    2013-01-01

    The aim of this investigation was to compare the microleakage level of fissure sealants prepared by a fissurotomy bur or pumice prophylaxis prior to acid etching. Materials and Methods: Ninety freshly extracted healthy maxillary premolar teeth were randomly selected for this investigation. Teeth were then divided into three fissure sealant preparatory groups of A: Fissurotomy bur + acid etch; B: Pumice prophylaxis + acid etch and C: Acid etch alone. Sealant was applied to the occlusal fissures of all specimens using a plastic instrument. This was to avoid any air trap under the sealant. Sample teeth were first thermocycled (1000 cycles, 20 s dwell time and then coated with two layers of nail varnish leaving 2 mm around the sealant. This was then followed by immersion in basic fuchsin 3%. Processed teeth were sectioned longitudinally and examined under a stereomicroscope for microleakage assessment using a score of 0-3. Collected data was then subjected to Kruskall-Wallis Analysis of Variance and Mann-Whitney U-test. P < 0.05 was considered as significant. Results: Teeth in fissurotomy bur and pumice prophylaxis groups had significantly reduced level of microleakage than those in acid etch alone (P = 0.005 and P = 0.003, respectively. Conclusion: Use of fissurotomy bur and pumice prophylaxis accompanied with acid etching appears to have a more successful reduction of microleakage than acid etch alone.

    1989-01-01

    We assessed neuropsychologically 106 children with acute lymphoblastic leukemia (ALL) who had all received cranial irradiation for the prevention of central nervous system (CNS) leukemia 1-13 years previously. Children were assessed for adverse late effects of their therapy, using age-appropriate Wechsler measures of overall intellectual ability and supplementary tests. Forty-five siblings near in age to the patients were tested as controls. The patients who had had the most intensive central nervous system (CNS) prophylaxis were found to have a WISC-R Full Scale IQ 17 points lower than the sibling control group. Performance IQ was more affected than verbal IQ. The patients were more easily distracted and less able to concentrate. The severity of the aftereffects was related to younger age at the time of CNS prophylaxis and to a higher dose of cranial irradiation but not to time since CNS prophylaxis. CNS prophylaxis using a combination of cranial irradiation and intrathecal methotrexate has lowered the incidence of CNS relapse in childhood ALL but is associated with considerable long-term morbidity in survivors

    Danhauer, Jeffrey L; Kelly, Allison; Johnson, Carole E

    2011-10-01

    Xylitol can be a prophylaxis for acute otitis media (AOM), especially when administered via chewing gum, but that vehicle has limitations for children. This review sought evidence for links of mother-child transmission of bacteria and as a vehicle for xylitol as a prophylaxis for dental caries and its translation to AOM in infants and young children. Qualitative systematic review. Combining output from 43 search strings used earlier and submitting 20 new strings to PubMed resulted in 14 studies (six were excluded; eight were included). Included studies had to be published in English-language, peer-reviewed journals; involve mothers using xylitol; and assess bacteria or caries in their children. Evaluation forms were completed for search, retrieval, and quality assessment of included studies. The studies showed that mothers' chewing xylitol gum was a prophylaxis against bacteria and caries in their children. A mother-child transmission model was presented as a possible vehicle for use in comprehensive prevention programs for AOM. Potential for xylitol use to prevent AOM warrants further study. A mother-child model may apply to AOM for transmission of bacteria and as a prophylaxis, but alternative vehicles like nasal sprays should be investigated for ease of use and effectiveness.

    2009-11-01

    Hepatic veno-occlusive disease (VOD) is a common complication of haematopoietic stem cell transplantation (HSCT), with reported incidences of 5-40% in children. Recently, defibrotide (DF) has been successfully used as prophylaxis and treatment of VOD. This study reports data on 63 human leucocyte antigen-matched HSCT performed in 57 children affected by beta thalassemia at very high risk for developing VOD (liver fibrosis, iron overload, hepatitis C virus infections, busulphan-based conditioning, methotraexate + ciclosporine). All patients received a busulphan-based conditioning regimen, either orally (four HSCT) or intravenously (59 HSCT). All patients received oral DF (40 mg/kg per day, final dose) as VOD prophylaxis from median day -9 to median day +29. In order to overcome the lack of oral paediatric formulations, a galenic formulation was administered. DF was well tolerated. Only one patient fulfilled Seattle Criteria for VOD diagnosis. This patient had discontinued DF 6 d prior to VOD onset, due to high risk of haemorrhage. We concluded that oral defibrotide prophylaxis and i.v. busulphan safely abated VOD incidence in high-risk patients who had undergone HSCT. A galenic preparation of oral DF also permits this treatment in low-weight patients. Costs of DF prophylaxis are acceptable considering the reduced incidence of VOD.

    This consensus document is an update of occupational and non-occupational prophylaxis guidelines in HIV-patients, promoting appropriate use of them, from the standpoint of care. This document has been approved by expert panel of SPNS, GESIDA, SEMST and different scientific societies related, after reviewing the results of efficacy and safety clinical trials, cohort and pharmacokinetic studies published in biomedical journals (PubMed and Embase) or presented at conferences and different guidelines. The strength of the recommendation and gradation of their evidence are based on the GRADE system. We have developed recommendations for assessing the risk of transmission in different types of exposure situations in which post-exposure prophylaxis should be recommended, special circumstances to consider, patterns of antiretroviral with the start and duration of early monitoring of tolerance and adherence to treatment, the subsequent monitoring of exposed persons regardless of whether they received post-exposure prophylaxis or not, and the need of psychological support. These new guidelines updated previous recommendations regarding occupational post-exposure prophylaxis and non-occupational, in adults and children.

    Empowering surgical nurses improves compliance rates for antibiotic prophylaxis after caesarean birth. This paper is a report of a study of the effect of empowering surgical nurses to ensure that patients receive antibiotic prophylaxis after caesarean birth. Despite the consensus that single dose antibiotic prophylaxis is beneficial for women have either elective or non-elective caesarean delivery, hospitals need methods to increase compliance rates. In a study in Israel in 2007 surgical nurses were empowered to ensure that a single dose of cefazolin was given to the mother after cord clamping. A computerized system was used to identify women having caesarean births, cultures sent and culture results. Compliance was determined by chart review. Rates of compliance, suspected wound infections, and confirmed wound infections in 2007 were compared to rates in 2006 before the policy change. Relative risks were calculated dividing 2007 rates by those in 2006, and 95% confidence intervals were calculated using Taylor's series that does not assume a normal distribution. Statistical significance was assessed using the chi-square test. The compliance rate was increased from 25% in 2006 to 100% in 2007 (chi-square test, P rates decreased from 16.8% (186/1104) to 12.6% (137/1089) after the intervention (relative risk 0.75, 95% confidence interval, 0.61-0.92). Surgical nurses can ensure universal compliance for antibiotic prophylaxis in women after caesarean birth, leading to a reduction in wound infections.

    Prosthetic joint infections remain a major complication of arthroplasty. At present, local and international guidelines recommend cefazolin as a surgical antibiotic prophylaxis at the time of arthroplasty. This retrospective cohort study conducted across 10 hospitals over a 3-year period (January 2006 to December 2008) investigated the epidemiology and microbiological etiology of prosthetic joint infections. There were 163 cases of prosthetic joint infection identified. From a review of the microbiological culture results, methicillin-resistant Staphylococcus aureus (MRSA) and coagulase-negative staphylococci were isolated in 45% of infections. In addition, polymicrobial infections, particularly those involving Gram-negative bacilli and enterococcal species, were common (36%). The majority (88%) of patients received cefazolin as an antibiotic prophylaxis at the time of arthroplasty. In 63% of patients in this cohort, the microorganisms subsequently obtained were not susceptible to the antibiotic prophylaxis administered. The results of this study highlight the importance of ongoing reviews of the local ecology of prosthetic joint infection, demonstrating that the spectrum of pathogens involved is broad. The results should inform empirical antibiotic therapy. This report also provokes discussion about infection control strategies, including changing surgical antibiotic prophylaxis to a combination of glycopeptide and cefazolin, to reduce the incidence of infections due to methicillin-resistant staphylococci.

    Full Text Available To elucidate the Chinese practice of intraocular antibiotics administration for prophylaxis after open globe injury.A cross-sectional questionnaire survey was performed online by scanning a Quickmark (QR code with smartphones at the 20th Chinese National Conference of Ocular Trauma in November 2014.A total of 153 (30.6% of all participators at the conference responded. Of the respondents, 20.9% were routinely administered with prophylactic intraocular injection of antibiotics at the conclusion of the primary eye repair, and 56.9% were used only in cases with high risk of endophthalmitis development. The intraocular route of delivery was mainly included with intracameral injection (47.9% and intravitreal injection (42.0%. Cephalosporins (53.8% and vancomycin (42.0% were the main choices of antibiotic agents, followed by fluoroquinolones (24.3%, and aminoglycosides (13.4%. Only 21.9% preferred a combination of two or more two drugs routinely. In addition, significantly more respondents from the referral eye hospital (92.7% replied using intraocular antibiotics injection for prophylaxis compared to those respondents from the primary hospital (69.4% (p = 0.001, Fisher's exact test.Intraocular antibiotics injection for post-traumatic endophthalmitis prophylaxis is widely used in China. However, the choice of antibiotic agents and the intraocular route of delivery vary. A well-designed clinical trial is needed to establish a standardized protocol of intraocular antibiotics administration for post-traumatic endophthalmitis prophylaxis.

    Although pegfilgrastim prophylaxis is expected to maintain the relative dose intensity (RDI) of chemotherapy and improve safety, information is limited. However, the optimal selection of patients eligible for pegfilgrastim prophylaxis is an important issue from a medical economics viewpoint. Therefore, this retrospective study identified factors that could predict these eligible patients to maintain the RDI. The participants included 166 cancer patients undergoing pegfilgrastim prophylaxis combined with chemotherapy in our outpatient chemotherapy center between March 2015 and April 2017. Variables were extracted from clinical records for regression analysis of factors related to maintenance of the RDI. RDI was classified into four categories: 100% = 0, 85% or predictive factors in patients eligible for pegfilgrastim prophylaxis to maintain the RDI. Threshold measures were examined using a receiver operating characteristic (ROC) analysis curve. Age [odds ratio (OR) 1.07, 95% confidence interval (CI) 1.04-1.11; P maintenance. ROC curve analysis of the group that failed to maintain the RDI indicated that the threshold for age was 70 years and above, with a sensitivity of 60.0% and specificity of 80.2% (area under the curve: 0.74). In conclusion, younger age, anemia (less), and administration of pegfilgrastim 24-72 h after chemotherapy were significant factors for RDI maintenance.

    Primary prophylaxis of bleeding is debated for children with portal hypertension because of the limited number of studies on its safety and efficacy, the lack of a known endoscopic pattern carrying a high-risk of bleeding for all causes, and the assumption that the mortality of a first bleed is low. We report our experience with these issues. From 1989 to 2014, we managed 1300 children with portal hypertension. Endoscopic features were recorded; high-risk varices were defined as: grade 3 esophageal varices, grade 2 varices with red wale markings, or gastric varices. Two hundred forty-six children bled spontaneously and 182 underwent primary prophylaxis. The results of primary prophylaxis were reviewed as well as bleed-free survival, overall survival and life-threatening complications of bleeding. High-risk varices were found in 96% of children who bled spontaneously and in 11% of children who did not bleed without primary prophylaxis (pportal hypertension. Life-threatening complications of bleeding were recorded in 19% of children with cirrhosis and high-risk varices who bled spontaneously. Ten-year probabilities of bleed-free survival after primary prophylaxis in children with high-risk varices were 96% and 72% for non-cirrhotic causes and cirrhosis respectively. Ten-year probabilities of overall survival after primary prophylaxis were 100% and 93% in children with non-cirrhotic causes and cirrhosis respectively. In children with portal hypertension, bleeding is linked to the high-risk endoscopic pattern reported here. Primary prophylaxis of bleeding based on this pattern is fairly effective and safe. In children with liver disease, the risk of bleeding from varices in the esophagus is linked to their large size, the presence of congestion on their surface and their expansion into the stomach but not to the child's age nor to the cause of portal hypertension. Prevention of the first bleed in children with high-risk varices can be achieved by surgery or endoscopic

  19. Death Associated with Inadequate Reassessment of Venous Thromboembolism Prophylaxis at and after Hospital Discharge.

    Science.gov (United States)

    2015-01-01

    Venous thromboembolism (VTE) prophylaxis, also known as thromboprophylaxis, reduces the risk of deep vein thrombosis, pulmonary embolism, and associated complications, including death, in high-risk patients. VTE prophylaxis is recommended for acutely ill, hospitalized medical patients at risk of thrombosis. Anticoagulants, the pharmacologic agents of choice to prevent VTE, are considered high-alert medications. By definition, therefore, anticoagulants bear a hightened risk of causing significant patient harm when they are used in error. As part of ongoing collaboration with a provincial death investigation service, ISMP Canada received a report of a fatal incident that involved continuation of VTE prophylaxis with enoxaparin for a patient discharge to a long-term care (LTC) facility from an acute care setting. The findings and recommendations from this case are charged to highlight the need to build routine reassessment of VTE prophylaxis into the process for discharging patients from the acute care setting and upon transfer to another facility or to primary care. The incident described in this bulletin highlights the importance of continually reassessing the need for VTE prophylaxis, especially at transitions of care, such as discharge from an acute care setting. Evidence and guidelines confirm the benefits of VTE prophylaxis in certain patients during a hospital stay for an acute illness, but the balance of benefits and risks may become unfavourable once the patient is discharged. Clear documentation from the acute care facility can assist the receiving facility and health-care providers, as well as family caregivers, when determining whether thromboprophylaxis is still warranted. Until clear guidance to continue thromboprophylaxis after acute care is available, health-care organizations and practitioners across the spectrum of care are urged to share and consider the strategies presented in this bulletin to ensure the safe use of VTE prophylaxis and improved

    Although over the past decade the management of invasive fungal infection has improved, considerable controversy persists regarding antifungal prophylaxis in solid organ transplant recipients. To identify the key clinical knowledge and make by consensus the high level recommendations required for antifungal prophylaxis in solid organ transplant recipients. Spanish prospective questionnaire, which measures consensus through the Delphi technique, was conducted anonymously and by e-mail with 30 national multidisciplinary experts, specialists in invasive fungal infections from six national scientific societies, including intensivists, anesthetists, microbiologists, pharmacologists and specialists in infectious diseases that responded to 12 questions prepared by the coordination group, after an exhaustive review of the literature in the last few years. The level of agreement achieved among experts in each of the categories should be equal to or greater than 70% in order to make a clinical recommendation. In a second term, after extracting the recommendations of the selected topics, a face-to-face meeting was held with more than 60 specialists who were asked to validate the pre-selected recommendations and derived algorithm. Echinocandin antifungal prophylaxis should be considered in liver transplant with major risk factors (retransplantation, renal failure requiring dialysis after transplantation, pretransplant liver failure, not early reoperation, or MELD>30); heart transplant with hemodialysis, and surgical re-exploration after transplantation; environmental colonization by Aspergillus, or cytomegalovirus (CMV) infection; and pancreas and intestinal transplant in case of acute graft rejection, hemodialysis, initial graft dysfunction, post-perfusion pancreatitis with anastomotic problems or need for laparotomy after transplantation. Antifungal fluconazole prophylaxis should be considered in liver transplant without major risk factors and MELD 20-30, split or living

    HIV prevention during pregnancy and lactation is critical for both maternal and child health. Pregnancy provides a critical opportunity for clinicians to elicit women's vulnerabilities to HIV and offer HIV testing, treatment and referral and/or comprehensive HIV prevention options for the current pregnancy, the postpartum period and safer conception options for future pregnancies. In this commentary, we review the safety of oral pre-exposure prophylaxis with tenofovir/emtricitabine in pregnant and lactating women and suggest opportunities to identify pregnant and postpartum women at substantial risk of HIV. We then describe a clinical approach to caring for women who both choose and decline pre-exposure prophylaxis during pregnancy and postpartum, highlighting areas for future research. Evidence suggests that pre-exposure prophylaxis with tenofovir/emtricitabine is safe in pregnancy and lactation. Identifying women vulnerable to HIV and eligible for pre-exposure prophylaxis is challenging in light of the myriad of individual, community, and structural forces impacting HIV acquisition. Validated risk calculators exist for specific populations but have not been used to screen and offer HIV prevention methods. Partner testing and engagement of men living with HIV are additional means of reaching at-risk women. However, women's vulnerabilities to HIV change over time. Combining screening for HIV vulnerability with HIV and/or STI testing at standard intervals during pregnancy is a practical way to prompt providers to incorporate HIV screening and prevention counselling. We suggest using shared decision-making to offer women pre-exposure prophylaxis as one of multiple HIV prevention strategies during pregnancy and postpartum, facilitating open conversations about HIV vulnerabilities, preferences about HIV prevention strategies, and choosing a method that best meets the needs of each woman. Growing evidence suggests that pre-exposure prophylaxis with tenofovir

    According to the global framework of eliminating human rabies, China is responding to achieve the target of zero human death from dog-mediated rabies by 2030. Chongqing is the largest municipality directly under central government in China. We described the epidemiological characteristics and post-exposure prophylaxis (PEP) of human rabies in this area, in order to provide a reliable epidemiology basis for further control and prevention of human rabies. The most updated epidemiological data for human rabies cases from 2007 to 2016 in Chongqing were collected from the National Disease Reporting Information System. A standardized questionnaire was applied to the human rabies cases or family members of cases as proxy to investigate the PEP situation. A total of 809 fatal human rabies cases were reported in Chongqing from 2007 to 2016. There was a trend of gradual annual decline about number of cases from 2007 to 2013, followed by stable levels until 2016. Rabies was mostly reported in summer and autumn; a majority of cases were noted in farmers (71.8%), especially in males (65.3%). The cases aged 35-74 and 5-14 years old accounted for 83.8% of all the cases. We collected information of 548 human rabies cases' rabies exposure and PEP situation. Of those, 95.8% of human rabies cases were victims of dog bites or scratch, and 53.3% of these dogs were identified as stray dogs. Only 4.0% of the domestic dogs were reported to have been vaccinated previously. After exposure, 87.8% of the 548 human rabies cases did not seek any medical services. Further investigation showed that none of the 548 cases received timely and properly standardized PEP. Human rabies remains a major public health problem in Chongqing, China. Dogs are the main reservoir and source of human rabies infection. Unsuccessful control of canine rabies and inadequate PEP of cases might be the main factors leading to the serious human rabies epidemic in this area. An integrated "One Health" approach should be

    Full Text Available In the absence of an effective vaccine, HIV continues to spread globally, emphasizing the need for novel strategies to limit its transmission. Pre-exposure prophylaxis (PrEP with antiretroviral drugs could prove to be an effective intervention strategy if highly efficacious and cost-effective PrEP modalities are identified. We evaluated daily and intermittent PrEP regimens of increasing antiviral activity in a macaque model that closely resembles human transmission.We used a repeat-exposure macaque model with 14 weekly rectal virus challenges. Three drug treatments were given once daily, each to a different group of six rhesus macaques. Group 1 was treated subcutaneously with a human-equivalent dose of emtricitabine (FTC, group 2 received orally the human-equivalent dosing of both FTC and tenofovir-disoproxil fumarate (TDF, and group 3 received subcutaneously a similar dosing of FTC and a higher dose of tenofovir. A fourth group of six rhesus macaques (group 4 received intermittently a PrEP regimen similar to group 3 only 2 h before and 24 h after each weekly virus challenge. Results were compared to 18 control macaques that did not receive any drug treatment. The risk of infection in macaques treated in groups 1 and 2 was 3.8- and 7.8-fold lower than in untreated macaques (p = 0.02 and p = 0.008, respectively. All six macaques in group 3 were protected. Breakthrough infections had blunted acute viremias; drug resistance was seen in two of six animals. All six animals in group 4 that received intermittent PrEP were protected.This model suggests that single drugs for daily PrEP can be protective but a combination of antiretroviral drugs may be required to increase the level of protection. Short but potent intermittent PrEP can provide protection comparable to that of daily PrEP in this SHIV/macaque model. These findings support PrEP trials for HIV prevention in humans and identify promising PrEP modalities.

    Men who have Sex with Men (MSM) have been affected disproportionately by the global HIV pandemic. Rates of consistent condom-use are low and there is a need for further biomedical prevention interventions to prevent new HIV infections. Post exposure prophylaxis (PEP) can reduce the risk of HIV, but uptake among MSM is low. Pre-exposure prophylaxis (PrEP), an innovative anti-retroviral-based HIV prevention tool might be an appropriate intervention for MSM who have recently accessed PEP that involves HIV negative individuals taking daily tenofovir+emtricitabine for HIV prevention. 44 MSM, attending a primary health-care level MSM-focused sexual health clinic in Cape Town, South Africa, who had initiated PEP were enrolled in this study. Participants were followed up after 2, 4 and 12 weeks. Self-administered electronic surveys were completed at the initial, 4 and 12 week visit. Barriers and facilitators to accessing PEP and remaining adherent were examined, as was knowledge about PrEP. Thirty-two participants (80 %) were <40 years of age (range 20-65 years). 35 % of the participants reported their reason for requiring PEP as condomless receptive anal intercourse. A further 20 % required PEP following condomless penetrative anal intercourse; 27.5 % required PEP due to a broken condom during receptive anal sex and 2 participants during insertive anal sex. Three participants did not complete 28 days of PEP or were lost to follow up. Over half (58.5 %) of the participants reported being completely adherent to their regime; under a third (31.7 %) reported missing one PEP dose; and 9.8 % reported missing more than one dose. 36/40 (90 %) had heard of PrEP and 30/40 (75 %) indicated that they would use PrEP if it were accessible to them. That we enrolled 44 MSM who accessed PEP from a Department of Health affiliated clinic over 12 months, speaks to the low uptake by MSM of PEP services in South Africa. Adherence was high and demonstrates that adherence

    The increasing prevalence of social networks provides researchers greater opportunities to evaluate and assess changes in public opinion and public sentiment towards issues of social consequence. Using trend and sentiment analysis is one method whereby researchers can identify changes in public perception that can be used to enhance the development of a social consciousness towards a specific public interest. The following study assessed Relative search volume (RSV) patterns for global warming (GW) and Climate change (CC) to determine public knowledge and awareness of these terms. In conjunction with this, the researchers looked at the sentiment connected to these terms in social media networks. It was found that there was a relationship between the awareness of the information and the amount of publicity generated around the terminology. Furthermore, the primary driver for the increase in awareness was an increase in publicity in either a positive or a negative light. Sentiment analysis further confirmed that the primary emotive connections to the words were derived from the original context in which the word was framed. Thus having awareness or knowledge of a topic is strongly related to its public exposure in the media, and the emotional context of this relationship is dependent on the context in which the relationship was originally established. This has value in fields like conservation, law enforcement, or other fields where the practice can and often does have two very strong emotive responses based on the context of the problems being examined.

    Casa Garrahan (CG) accommodates children with complex conditions referred nationwide; these children are seen in children's hospitals located in the Autonomous City of Buenos Aires. Varicella is a highly-contagious disease, with attack rates of up to 90% among susceptible individuals. In closed communities, the implementation of outbreak control measures is critical. To describe the characteristics of children exposed to varicella at CG, the implemented prophylaxis measures and their effectiveness. Prospective, cohort study. Children exposed to varicella at CG between2008 and 2013, their demographic and clinical characteristics, immunization and/or history of varicella, prophylaxis measures, and secondary attack rate were assessed. N: 107. Fifty-three percent (n: 57) were girls. Their median age was 84 months old [interquartile range (IQR): 24-144]. Ninety-five percent (n: 102) had an underlying disease [hemato-oncological disease: 39% (n: 42); neurological disease: 18% (n: 19); congenital heart disease: 9% (n: 10); and post-operative period: 65 (n: 6)]. Fifty percent had some degree of immunosuppression (n: 54). Twenty-nine percent (n: 31) referred to have had varicella; 27% (n: 29) indicated that they never had the infection; and 41% (n: 44) did not recall a history of varicella. Only 3% (n: 3) had been vaccinated. Based on their immune status, age and history of varicella, acyclovir was indicated as prophylaxis in 61% (n: 65); immunization in 10% (n: 10); and gamma globulin in 1 patient. No adverse effects were observed in relation to the different prophylaxis measures. No secondary cases were observed at 30 days. Implemented measures were effective to prevent secondary cases. Among healthy and immunocompromised children, prophylaxis with acyclovir was effective and well-tolerated.

    Highlights: •The controller of a standard SCD is labeled as an “MR-unsafe”. •No commercially available “MR-safe” SCDs. •Standard SCDs can be used in iMRI by placing the device outside the MRI scanner room. •Using serial extension tubing did not cause device failure. -- Abstract: Purpose: Venous thromboembolism (VTE) is a common cause of morbidity and mortality in hospitalized and surgical patients. To reduce risk, perioperative VTE prophylaxis is recommended for cancer patients undergoing surgical or interventional procedures. Magnetic resonance imaging (MRI) is increasingly used in interventional oncology when alternative imaging modalities do not adequately delineate malignancies. Extended periods of immobilization during MRI-guided interventions necessitate an MR compatible sequential compression device (SCD) for intra-procedural mechanical VTE prophylaxis. Such devices are not commercially available. Materials and methods: A standard SCD routinely used at our institution for VTE prophylaxis during interventional procedures was used. To satisfy MR safety requirements, the SCD controller was placed in the MR control room and connected to the compression sleeves in the magnet room through the wave guide using tubing extensions. The controller pressure sensor was used to monitor adequate pressure delivery and detect ineffective low or abnormal high pressure delivery. VTE prophylaxis was provided using the above mentioned device for 38 patients undergoing MR-guided ablations. Results: There was no evidence of device failure due to loss of pressure in the extension tubing assembly. No interference with the anesthesia or interventional procedures was documented. Conclusion: Although the controller of a standard SCD is labeled as “MR-unsafe”, the SCD can be used in interventional MR settings by placing the device outside the MR scanner room. Using serial tubing extensions did not cause device failure. The described method can be used to provide

    The global scale-up of AIDS treatment initiatives during the first decade of the twenty-first century has been referred to as a kind of 'pharmaceuticalisation' of public health, a trend that is now building in the area of HIV prevention. This paper traces the emergence and increased uptake of pre-exposure prophylaxis (PrEP), antiretroviral medications that can keep HIV negative individuals from becoming infected, placing it within the broader (re)casting of HIV prevention as a medical and technological problem that has been central to the recent 'end of AIDS' discourse. While HIV prevention discourses have been grounded in a neoliberal calculus of individual responsibility since the late 1990s, PrEP constitutes a pharmaceutical extension of the responsibilised sexual subject. Central to this extension are the acknowledgment of one's risk and a willingness to take pre-emptive medical action to secure a future without HIV. For men who have sex with men, a population heavily targeted for biomedical interventions in the United States, PrEP marks a shift in moral discourses of what it means to be a responsible sexual subject. Characteristics of the pharmaceutical extension of the neoliberal sexual subject are explored through an examination of a New York City-based PrEP promotional campaign.

    Full Text Available ABSTRACT Background The efficacy of nonselective β-blocker and endoscopic procedures, such as endoscopic variceal ligation, as primary prophylaxis of variceal hemorrhage in cirrhotic adults was demonstrated by numerous controlled trials, but in pediatric population, few are the number of studies. Objective The objective of this study is to evaluate the primary prophylaxis with β-blocker in cirrhotic children and adolescents with portal hypertension. Methods This is a cohort study encompassing 26 cirrhotic patients. β-blocker prophylaxis was performed with propranolol. When contraindicated the use of β-blocker, or if side effects presents, the patients were referred to endoscopic therapy with band ligation. Patients were evaluated by endoscopy, and those who had varicose veins of medium and large caliber or reddish spots, regardless of the caliber of varices, received primary prophylaxis. Results Of the 26 patients evaluated, 9 (34.6% had contraindications to the use of propranolol and were referred for endoscopic prophylaxis. Six (35.3% of the 17 patients who received β-blocker (propranolol, had bled after a median follow-up time of 1.9 years. β-blockage dosage varied from 1 mg/kg/day to 3.1 mg/kg/day and seven (41.2% patients had the propranolol suspended due to fail of the β-blockage or adverse effects, such as drowsiness, bronchospasm and hypotension. Patients who received endoscopic prophylaxis (elastic bandage had no bleeding during the follow-up period. Conclusion All of the patients that had upper gastroinstestinal bleeding in this study were under propranolol prophylaxis. The use of propranolol showed a high number of contraindications and side effects, requiring referral to endoscopic prophylaxis. The endoscopic prophylaxis was effective in reducing episodes of bleeding.

    To determine the effect of secondary penicillin prophylaxis on echocardiographic diagnosed valvular changes in patients with rheumatic heart disease or history of acute rheumatic fever in the Townsville Health district. Patients with known were identified from the North Queensland register, serial echocardiogram results and number of secondary penicillin prophylaxis doses received in 2014 were collated. Descriptive statistics were utilised. Townsville Hospital and outreach clinics within the Townsville Health catchment zone. All patients diagnosed with acute rheumatic fever or rheumatic heart disease between 2010 and October 2013 who had serial echocardiograms prior to and post commencement of secondary penicillin prophylaxis were included. All patients were of Aboriginal or Torres Strait Islander descent. Progression of echocardiographic valvular changes and association with secondary penicillin prophylaxis compliance. Compliance with secondary penicillin prophylaxis among the study population was a secondary outcome measure. Twenty-three patients were recruited. Only those patients who were compliant with secondary penicillin prophylaxis had any improvement in valvular changes on echocardiogram. Four of six patients without any baseline valvular involvement developed new valvular changes. Seventy percent of patients received >75% of secondary penicillin prophylaxis doses. This small study of patients in Townsville suggests that with good secondary penicillin prophylaxis compliance there is regression of some cardiac lesions over time in people with rheumatic heart disease. Furthermore the natural history of acute rheumatic fever in the Indigenous population is progressive requiring strict adherence to secondary penicillin prophylaxis. Prospective studies or use of data from the nationwide RHD register and standardised reporting of cardiac echocardiograms will provide more robust evidence. © 2017 National Rural Health Alliance Inc.

    The purpose of this systematic review was to investigate the efficacy of nonsteroidal anti-inflammatory drug (NSAID) prophylaxis for preventing heterotopic ossification (HO) in the setting of hip arthroscopy. A systematic search was performed in duplicate for studies comparing the use of NSAID prophylaxis for HO in the setting of hip arthroscopy until March 2015. Study parameters--including sample size, incidence of HO, adverse effects, and level of symptoms--were obtained. Furthermore, the level of evidence of studies was collected and quality assessment was performed. The difference in incidence as well as pooled odds ratios were calculated and analyzed to compare no prophylaxis versus NSAID prophylaxis. This systematic review identified 5 studies, consisting of 1,662 patients, investigating NSAID prophylaxis in hip arthroscopy. HO was diagnosed with the use of postoperative hip radiographs at follow-up, with 95% of cases classified using the Brooker classification. The incidence of HO was 13.4% without NSAID prophylaxis and 3.3% with NSAID prophylaxis. Pooled odds ratios from the prospective studies were 0.07 (95% confidence interval [CI], 0.02 to 0.28; P = .0002; I(2) = 0%), showing with statistical significance that NSAID prophylaxis decreased the incidence of HO. The retrospective data similarly showed pooled odds ratios of 0.03 (95% CI, 0.00 to 1.43); P = .08; I(2) = 84%), although it was not statistically significant. Most of the patients who experienced HO in both groups were not reported to be symptomatic. Adverse effects and compliance were not consistently reported. The available orthopaedic literature suggests that the incidence of postoperative HO may be decreased with the use of NSAID prophylaxis in hip arthroscopy. However, the evidence is unclear regarding NSAID drug regimen choice, drug compliance, and adverse effects. Level III, systematic review of Level I, Level II, and Level III studies.

    2018-03-01

    To determine the optimal antibiotic prophylaxis strategy for transrectal prostate biopsy (TRPB) as a function of the local antibiotic resistance profile. We developed a decision-analytic model to assess the cost-effectiveness of four antibiotic prophylaxis strategies: ciprofloxacin alone, ceftriaxone alone, ciprofloxacin and ceftriaxone in combination, and directed prophylaxis selection based on susceptibility testing. We used a payer's perspective and estimated the health care costs and quality-adjusted life-years (QALYs) associated with each strategy for a cohort of 66-year-old men undergoing TRPB. Costs and benefits were discounted at 3% annually. Base-case resistance prevalence was 29% to ciprofloxacin and 7% to ceftriaxone, reflecting susceptibility patterns observed at the Minneapolis Veterans Affairs Health Care System. Resistance levels were varied in sensitivity analysis. In the base case, single-agent prophylaxis strategies were dominated. Directed prophylaxis strategy was the optimal strategy at a willingness-to-pay threshold of $50,000/QALY gained. Relative to the directed prophylaxis strategy, the incremental cost-effectiveness ratio of the combination strategy was $123,333/QALY gained over the lifetime time horizon. In sensitivity analysis, single-agent prophylaxis strategies were preferred only at extreme levels of resistance. Directed or combination prophylaxis strategies were optimal for a wide range of resistance levels. Facilities using single-agent antibiotic prophylaxis strategies before TRPB should re-evaluate their strategies unless extremely low levels of antimicrobial resistance are documented.

    The concept of usability has become an increasingly important consideration in the design of all kinds of technology. As more products are aimed at global markets and developed through internationally distributed teams, usability design needs to be addressed in global terms. Interest in usability as a design issue and specialist area of research and education has developed steadily in North America and Europe since the 1980's. However, it is only over the last ten years that it has emerged as a global concern. Global Usability provides an introduction to the important issues in globalizing des

    Towards the end of the twentieth century, significant success was achieved in reducing incidence in several global HIV epidemics through ongoing prevention strategies. However, further progress in risk reduction was uncertain. For one thing, it was clear that social vulnerability had to be addressed, through research on interventions addressing health systems and other structural barriers. As soon as antiretroviral treatment became available, researchers started to conceive that antiretrovirals might play a role in decreasing either susceptibility in uninfected people or infectiousness among people living with HIV. In this paper we focus on the origin, present status, and potential contribution of pre-exposure prophylaxis (PrEP) within the combination HIV prevention framework. After a phase of controversy, PrEP efficacy trials took off. By 2015, daily oral PrEP, using tenofovir alone or in combination with emtricitabine, has been proven efficacious, though efficacy seems heavily contingent upon adherence to pill uptake. Initial demonstration projects after release of efficacy results have shown that PrEP can be implemented in real settings and adherence can be high, leading to high effectiveness. Despite its substantial potential, beliefs persist about unfeasibility in real-life settings due to stigma, cost, adherence, and potential risk compensation barriers. The strategic synergy of behavioural change communication, biomedical strategies (including PrEP), and structural programmes is providing the basis for the combination HIV prevention framework. If PrEP is to ever become a key component of that framework, several negative beliefs must be confronted based on emerging evidence; moreover, research gaps regarding PrEP implementation must be filled, and appropriate prioritization strategies must be set up. Those challenges are significant, proportional to the impact that PrEP implementation may have in the global response to HIV.

    ENDORSE (Epidemiologic International Day for the Evaluation of Patients at Risk for Venous Thromboembolism in the Acute Hospital Care Setting), is a multinational, cross-sectional survey of venous thromboembolism (VTE) risk prevalence and effective prophylaxis in the acute hospital care setting. Three Irish hospitals enrolled in the study. The American College of Chest Physicians (ACCP) guidelines were employed to evaluate VTE risk and prophylaxis. Of 552 patients, 297 (53.8%) and 255 (46.2%) were categorised as surgical or medical, respectively, with 175 (59%) surgical and 109 (43%) medical patients deemed to be at risk for VTE. Of these, only 112 (64%) and 51 (47%) received recommended VTE prophylaxis, respectively. The results are consistent with those observed in other countries and demonstrate a high prevalence of risk for VTE and a low rate of prophylaxis use, particularly in medical patients. Awareness of VTE guidelines should be an integral component of health policy.

    Full Text Available Secondary prophylaxis with rFVIIa has been the subject of several publications in the past few years. However, there is no general consensus on how this treatment should be put into practice, as publications have been very heterogeneous in the dosing schedule they report. Furthermore, the mechanism of action of rFVIIa and its short half life have been used as arguments against its role in prophylaxis. There have been a series of recent publications that show that rFVIIa can traffic through the intact endothelium and be stored in the subendothelium of several organs for a prolonged period of time. In order to consensuate the role of rFVIIa in prophylaxis, a group of experts from Argentina, resumed available information regarding pharmacology and clinical experience with this treatment, and developed a series of recommendations to use this drug in the prophylaxis setting.

    Venous thromboembolism (VTE) is a significant perioperative risk with many common orthopaedic procedures. Currently, there is no standardized recommendation for the use of VTE prophylaxis during anterior cruciate ligament (ACL) reconstruction. This study sought to evaluate the current prophylactic practices of fellowship-trained sports medicine orthopaedic surgeons in the United States. Very few surgeons use perioperative VTE prophylaxis for ACL reconstructive surgery. Survey. Surveys were emailed to the alumni networks of 4 large ACGME-accredited sports medicine fellowship programs. Questions were focused on their current use of chemical and nonchemical VTE prophylaxis. Surveys were completed by 142 surgeons in the United States, yielding a response rate of 32%. Of those who responded, 50.7% stated that they routinely use chemical prophylaxis, with 95.5% of those using aspirin (acetylsalicylic acid [ASA]). There was no standardized dosing protocol, with respondents using ASA 325 mg once (46%) or twice daily (26%) or ASA 81 mg once (18%) or twice (10%) daily. The most common reason for not including chemical prophylaxis within the reconstruction procedure was that it is unnecessary given the low risk of VTE. Physicians also based their prophylaxis regimen more on their own clinical experience than concern for litigation. Half of all sports medicine fellowship-trained surgeons surveyed routinely use chemical VTE prophylaxis after ACL reconstruction, with more than 90% of those using ASA. Of those using ASA, there was no prevailing dosing protocol. For those not using chemical prophylaxis, the most important reason was that it was felt to be unnecessary due to the risks outweighing the benefits. Those who do not regularly use chemical prophylaxis would be willing to, however, if a patient had a personal or family history of clotting disorder or is currently on birth control. Additionally, clinical experience was the primary driver for a current prophylaxis protocol

    Although the usefulness of antimicrobial prophylaxis for clean-contaminated surgery has been recognized, only a few randomized controlled studies on the duration of administration after hepatectomy have been performed. We investigated the duration of antimicrobial prophylaxis after hepatectomy. The subjects were 180 patients who underwent hepatectomy without reconstruction of the biliary or intestinal tract between April 2003 and March 2006 at our department. The patients were randomly allocated to groups to be treated with flomoxef sodium as antimicrobial prophylaxis for 2 days (89 patients) or 5 days (91 patients), including the operation day. The presence or absence of systemic inflammatory response syndrome (SIRS) and infections was investigated. No significant differences were noted in patient background between the two groups. Infections occurred in seven and six patients in the 2 day and 5 day treatment groups (7.9% and 6.6%), respectively, showing no significant difference between the two groups. No significant difference was noted when the cases were divided into surgical site infections and remote infections. The positive rate of SIRS was significantly higher in the 2 day treatment group than in the 5 day treatment group on days 2 and 3 after surgery. The risk factors in patients who developed infections were blood loss, operation time and the complication of biliary fistula. Two day administration of flomoxef sodium may be sufficient for antimicrobial prophylaxis after hepatectomy. However, when SIRS is positive on post-operative day 2, and induction of liver failure is of concern, it may be safer to continue antimicrobial drug administration until SIRS is eliminated.

    Nevirapine and cotrimoxazole are associated with hematologic toxicities and skin-rash. Safety of their concurrent use for prophylaxis over extended periods among HIV-exposed uninfected infants has not been previously assessed. Secondary data analysis of the 'HIV Prevention Trials Network-046 protocol' (version 2.0), a phase-III, randomized, placebo-controlled trial that assessed efficacy and safety of nevirapine prophylaxis against breast milk transmission of HIV-1. Trial infants received 6-month study nevirapine/placebo, and standard-of-care peripartum single-dose nevirapine+/- zidovudine 'tail', and cotrimoxazole prophylaxis from 6 weeks through breastfeeding cessation. Adverse events were monitored using United States Division of AIDS Toxicity Tables (2004). Risk of neutropenia, anemia and skin-rash in the cotrimoxazole + nevirapine and the cotrimoxazole + placebo groups were compared using negative-binomial regression. Incidence of neutropenia and/or anemia, and skin-rash was highest during the first 6 weeks of life and declined, thereafter, regardless of study group. Time to first adverse event after 6 weeks was similar in cotrimoxazole + nevirapine and cotrimoxazole + placebo groups: hazard ratio (95% confidence interval) was 1.26 (0.96-1.66) for neutropenia and/or anemia (all grades), 1.27 (0.80-2.03) for neutropenia and/or anemia (grade ≥3) and 1.16 (0.46-2.90) for skin-rash (grade ≥2). There were no statistically significant differences in immediate (6 weeks-6 months) and long-term (6-12 months) adverse event risk among infants on cotrimoxazole + nevirapine versus cotrimoxazole + placebo. Extended nevirapine and cotrimoxazole prophylaxis through 6 months of age among HIV-exposed uninfected infants did not appear to increase the immediate or long-term risk of neutropenia, anemia or skin-rash. Concurrent use beyond 6 months, however, needs to be evaluated.

    Prostate cancer is the most common solid cancer affecting men in Ireland. Transrectal ultrasound (TRUS) biopsies of the prostate are routinely performed to diagnose prostate cancer. They are, in general, a safe procedure but are associated with a significant risk of infective complications ranging from fever, urinary tract infection to severe urosepsis. At present, there are no recommended national guidelines on the use of antibiotic prophylaxis to minimise the risk of infective complications post-TRUS biopsy.

    The objective of this study was to evaluate the coagulation profile by thromboelastography in morbidly obese patients who undergo bariatric surgery. Morbid obesity entails increased risk for thromboembolic events. There is no clear protocol for thromboembolic prophylaxis, regarding timing and length of treatment, in bariatric surgery. Thromboelastography provides data on a coagulation process from creation of the clot until the fibrinolysis. Ninety-three morbidly obese patients were prospectively recruited within a 2-year period. Coagulation profile was measured by thromboelastography before surgery, in the immediate postoperative period, within 3 h from surgery, and in the late postoperative period, within 10-14 days after surgery. Venous thromboembolic prophylaxis was achieved by giving low molecular weight heparin (LMWH), once a day. Of the eligible patients, 67 underwent sleeve gastrectomy while 23 underwent Roux-en-Y gastric bypass. Normal values of coagulation factor function, clotting time, and fibrin function, as measured by R, K, and α (angle), were demonstrated in addition to higher maximal amplitude (MA) values, reflecting increased function of platelets. The average MA value before the surgery was above normal and continued rising consistently in the immediate postoperative as well as in the early postoperative period. Morbidly obese patients have a strong tendency toward thrombosis, as demonstrated by pathologically elevated MA values. Altered coagulation profiles were demonstrated 2 weeks postoperatively; thus, prophylaxis that continued at least for 2 weeks after bariatric surgery should be considered. Since LMW heparin is not sufficient alone as thromboembolic prophylaxis, we recommend adding antiplatelet therapy. Further evaluation of appropriate thromboprophylaxis is warranted.

    Full Text Available Treatment and prophylaxis of acute respiratory infections remain serious social and economical problem. Modern medicine estimates immunomodulators as one of promising methods of treatment and preventing of acute respiratory infections (ARI especially in frequently and long ailing children. Prophylactic administration of immunomodulators allows decreasing the risk of recurrent ARI, and treatment with these drugs in acute phase shortens terms of a disease and compensates immunosuppression.

    Although the prophylactic administration of indomethacin in extremely low-birth weight infants reduces the frequency of patent ductus arteriosus and severe intraventricular hemorrhage, it does not appear to provide any long-term benefit in terms of survival without neurosensory and cognitive outcomes. Considering the increased drug-induced reduction in renal, intestinal, and cerebral blood flow, the use of prophylaxis cannot be routinely recommended in preterm neonates. However, a better unde...

    Model-based studies of antiviral use to mitigate the impact of moderate and severe influenza pandemics implicitly take the viewpoint of a central public health authority. However, it seems likely that the key decision of when to use antivirals will be made at the household level. We used a stochastic compartmental model of the transmission of influenza within and between households to evaluate the expected mortality under two strategies: households saving available antivirals for treatment only and households implementing prophylaxis as well as treatment. Given that every individual in the population was allocated a single course of antivirals, we investigated the impact of these two strategies for a wide range of AVED, the efficacy of antivirals in preventing death in severe cases (AVED=1 for complete protection). We found a cross-over point for our baseline parameter values in a regime where antivirals were still highly effective in reducing the chance of death: below AVED=0.9 the optimal strategy was for households to use both treatment and prophylaxis. We also considered the possibility that a small number of households might "cheat" by choosing to follow the treatment-only strategy when other households were following treatment with prophylaxis. The cross-over point for cheating households was considerably lower, at AVED=0.6, but substantially above 0. These results suggest that unless antivirals are almost completely effective in reducing the chance of death in serious cases, households will likely be better served implementing prophylaxis as well as treatment. More generally, our study illustrates the potential value of considering viewpoints other than a central authority when conducting model-based analysis of interventions against infectious disease.

    Sucralfate is widely used as a cytoprotective agent in patients with peptic ulcer and other intestinal mucosal injury. The aim of this study is to investigate whether sucralfate has any effect on the prevention and treatment of hypoxia/reoxygenation-induced intestinal injury. Four groups of 10 1-day-old rat pups were studied. Hypoxia/reoxygenation (H/O)-induced intestinal injury was created. Group 1 was subjected to H/O just after birth and sacrificed at the end of the third day (Treatment Control). Group 2 was subjected to H/O just after birth and treated with sucralfate for 3 days. They were sacrificed at the end of the third day (Treatment). Group 3 was subjected to H/O on the third day after birth and then sacrificed (Prophylaxis Control). Group 4 was treated with sucralfate for the first 3 days, then H/O was created. Just after H/O, the pups were sacrificed (Prophylaxis). The intestinal tissues were harvested for histopathological investigation. Malondialdehyde (MDA) levels in the intestinal tissues were determined. The mucosal injury grades of the treatment and prophylaxis groups were significantly lower than those of control groups (p<0.05). The mean MDA level in the treatment and prophylaxis groups were 0.42+/-0.17 and 0.21+/-0.23 nmol/mg respectively. The MDA levels of both groups were significantly lower than in the control groups (p<0.05). The present study shows that sucralfate has beneficial effects in an experimental model of hypoxia/reoxygenation-induced intestinal injury.

    Antibiotic prophylaxis is a key component of the prevention of surgical site infection (SSI). Failure to manage antibiotic prophylaxis effectively may increase the risk of SSI. This study aimed to examine the effects of antibiotic prophylaxis on SSI risk. A retrospective cohort study was conducted among patients having general surgery between May 2012 and June 2015 at the University of Washington Medical Center. Peri-operative data extracted from hospital databases included patient and operation characteristics, intra-operative medication and fluid administration, and survival outcome. The effects of antibiotic prophylaxis and potential factors on SSI risk were estimated using multiple logistic regression and were expressed as risk ratios (RRs). A total of 4,078 patients were eligible for analysis. Of these, 180 had an SSI. Mortality rates within and after 30 days were 0.8% and 0.3%, respectively. Improper antibiotic redosing increased the risk of SSI (RR 4.61; 95% confidence interval [CI] 1.33-15.91). Other risk factors were in-patient status (RR 4.05; 95% CI 1.69-9.66), smoking (RR 1.63; 95% CI 1.03-2.55), emergency surgery (RR 1.97; 95% CI 1.26-3.08), colectomy (RR 3.31; 95% CI 1.19-9.23), pancreatectomy (RR 4.52; 95% CI 1.53-13.39), proctectomy (RR 5.02; 95% CI 1.72-14.67), small bowel surgery (RR 6.16; 95% CI 2.13-17.79), intra-operative blood transfusion >500 mL (RR 2.76; 95% CI 1.45-5.26), and multiple procedures (RR 1.40; 95% CI 1.01-1.95). These data demonstrate that failure to redose prophylactic antibiotic during long operations increases the risk of SSI. Strengthening a collaborative surgical quality improvement program may help to eradicate this risk.

  5. Reviewing current and emerging antiemetics for chemotherapy-induced nausea and vomiting prophylaxis.

    2015-01-01

    This review provides background information on chemotherapy-induced nausea and vomiting (CINV) classification and pathophysiology and reviews various antiemetic agents for CINV prophylaxis, including corticosteroids, serotonin receptor antagonists (5-HT3 RAs), tachykinin NK1 receptor antagonists (NK1 RAs), and olanzapine. Other less commonly used agents are briefly discussed. Practical considerations are reviewed as well, including emetogenicity of chemotherapeutic regimens, patient-specific risk factors for CINV, principles of CINV management, health economics outcome research, and quality of life. Available data on the newly FDA-approved antiemetic combination netupitant/palonosetron (NEPA) is also reviewed. Prevention of CINV is an important goal in managing patients with cancer and is especially difficult with respect to nausea and delayed CINV. Corticosteroids are a mainstay of CINV prophylaxis and are usually given in combination with other therapies. The 5-HT3 RA palonosetron has shown increased efficacy over other agents in the same class for prevention of delayed emesis with moderately emetogenic chemotherapy and NK1 RAs improve emesis prevention in combination with 5-HT3 RAs and dexamethasone. Olanzapine has shown efficacy for CINV prophylaxis and the treatment of breakthrough CINV. The new combination therapy, NEPA, has been shown to be efficacious for the prevention of acute, delayed, and overall CINV. Risk factors that have been identified for CINV include gender, age, and alcohol intake. It is important to assess the emetogenicity of chemotherapy regimens as well as the potential impact of patient risk factors in order to provide adequate prophylaxis. Acute and delayed CINV are severe, burdensome side effects of chemotherapy; however, new data on prevention and the discovery of new agents can further improve CINV control.

    Study the effectiveness of preventive vaccine prophylaxis of chicken pox in military collectives. In the focus of chicken pox, 200 servicemen of the new addition by conscription were immunized once against chicken pox; 97 servicemen by conscription of the new addition (comparison group) were not vaccinated. Epidemiologic and immunologic effectiveness of conduction of preventive vaccine prophylaxis in chicken pox focus were studied. In the group of 200 soldiers, that were present in the focus of infection and were immunized once against chicken pox, only 2 cases of this disease were registered (10 per thousand). In the comparison group, that consisted of 97 unvaccinated servicemen, chicken pox disease was registered in 7 individuals (72 per thousand). Epidemiologic effectiveness of preventive vaccine prophylaxis of chicken pox amounted to 86%. Immunologic effectiveness of vaccination 2-3 weeks after the immunization was 42%, and 2 months after--44%. Local reactions in the form of hyperemia (up to 1.5 cm) and edema were noted in 10% of the vaccinated at the location of preparation administration; in 1.7%--general reaction in the form of temperature increase to 37.8°C was observed. Post-vaccinal complications in the immunized group were not detected. Preventive vaccination of servicemen allows to minimize the spread of chicken pox, however can not serve as means of complete elimination of the infection from military collectives.

    Full Text Available Introduction: prophylaxis with granulocyte colony-stimulating factors (G-CSF is indicated for reduction in the duration of neutropenia and the incidence of febrile neutropenia in patients treated with cytotoxic chemotherapy for malignancy.
Objective: to evaluate the budgetary impact for the Italian NHS.
Design: a decision-analytic model has been developed to analyze the budget impact from the national health care system perspective. Costs include direct healthcare costs to the public payer of G-CSFs as well as their administration costs and costs of FN-related events. The comparison has been done using prophylaxis with G‑CSF (filgrastim for 11 days, pegfilgrastim, lenograstim for 11 days and antibiotics.
Patients and participants: The population of interest for the analysis were patients with breast cancer in stage II and III and patients with non-Hodgkin’s lymphoma (NHL.
Main outcome measures and results: for all the three patients group (NHL, Breast II and III, and for all the chemotherapy regimens (CHOP 21 and R-CHOP 21 for NHL, AC-T, TAC and TC for Breast stage II and III the budget impact analyses shows a cost reduction for the Italian NHS, as a result of an increase of the use of pegfilgrastim.
Conclusions: in Italy, a treatment strategy including pegfilgrastim as either primary or secondary prophylaxis provides value for money.

    Currently recommended prophylactic regimens for Plasmodium falciparum malaria are associated with a high incidence of adverse events and/or suboptimal efficacy. In a double-blind, placebo-controlled, randomized clinical trial in western Kenya, adult volunteers received a treatment course of atovaquone/proguanil hydrochloride (250 mg/100 mg per tablet) to eliminate preexisting infection. Immediately thereafter, subjects were randomized to one of the three prophylactic regimens to receive one atovaquone/proguanil tablet daily (n = 68), two atovaquone/proguanil tablets daily (n = 65), or placebo (n = 65) for 10 weeks. The study endpoint for any subject was the development of parasitemia, evident on blood smear, during prophylaxis. Of the evaluable subjects, all in the low-dose (54 of 54) and high-dose (54 of 54) atovaquone/proguanil groups remained malaria-free during the 10-week prophylaxis period, in contrast to only 48% (26 of 54) in the placebo group (P proguanil prophylactic regimens were as well tolerated as placebo. Thus, atovaquone/proguanil appears to be highly efficacious and safe as prophylaxis for P. falciparum malaria.

    Full Text Available Antineoplastic drug induced nausea and vomiting (AINV is a major adverse event which deeply impacts the quality of life of children with cancer. It additionally causes distress to parents and negatively impacts compliance to therapy. A robust AINV prophylaxis regimen is essential to achieve complete control; and prevent anticipatory, breakthrough and refractory AINV. With a wide array of available anti-emetics, standard guidelines for their use are crucial to ensure uniform and optimum prophylaxis. Chemotherapeutic agents are classified as having high, moderate, low or minimal emetic risk based on their potential to cause emesis in the absence of prophylaxis. Three drug regimen with aprepitant, ondansetron/granisetron and dexamethasone is recommended for protocols with high emetic risk. Although approved in children ≥12 years, there is mounting evidence for the use of aprepitant in younger children too. In protocols with moderate and low emetic risk, combination of ondansetron/granisetron and dexamethasone; and single agent ondansetron/granisetron are recommended, respectively. Metoclopramide is an alternative when steroids are contraindicated. Olanzapine and lorazepam are useful drugs for breakthrough AINV and anticipatory AINV. Knowledge of pediatric dosage, salient adverse events, drug interactions as well as cost of drugs is essential to prescribe anti-emetics accurately and safely in resource constrained settings. Non pharmacological interventions such as hypnosis, acupressure and psychological interventions can benefit a sub-group of patients without significant risk of adverse events.

    Prophylaxis and treatment with antiretroviral drugs have resulted in a very low rate of mother-to-child transmission (MTCT) of HIV during recent years. Registration of new antiretroviral drugs, modification of clinical praxis, updated general treatment guidelines and increasing knowledge about MTCT have necessitated regular revisions of the recommendations for 'Prophylaxis and treatment of HIV-1 infection in pregnancy'. The Swedish Reference Group for Antiviral Therapy (RAV) has updated the recommendations from 2013 at an expert meeting 19 September 2017. In the new text, current treatment guidelines for non-pregnant are considered. The most important revisions are that: (1) Caesarean section and infant prophylaxis with three drugs are recommended when maternal HIV RNA >150 copies/mL (previously >50 copies/mL). The treatment target of undetectable HIV RNA remains unchanged <50 copies/mL; (2) Obstetric management and mode of delivery at premature rupture of the membranes and rupture of the membranes at full term follow the same procedures as in HIV negative women; (3) Vaginal delivery is recommended to a well-treated woman with HIV RNA <150 copies/mL regardless of gestational age, if no obstetric contraindications are present; (4) Treatment during pregnancy should begin as soon as possible and should continue after delivery; (5) Ongoing well-functioning HIV treatment at pregnancy start should usually be retained; (6) Recommended drugs and drug combinations have been updated.

    The most commonly used antibacterial prophylaxis during autologous stem cell transplants (ASCT) for multiple myeloma (MM) involves a fluoroquinolone, such as ciprofloxacin or levofloxacin. We assessed the impact of adding doxycycline to ciprofloxacin as routine antibacterial prophylaxis in these patients. We retrospectively reviewed electronic medical records and our ASCT database to analyze rates and types of bacterial infections in MM patients who underwent ASCT in our institution. Among 419 patients, 118 received ciprofloxacin alone (cipro group), and 301 ciprofloxacin and doxycycline (cipro-doxy group). Neutropenic fever (NF) developed in 63 (53%) and 108 (36%) patients of the cipro and cipro-doxy groups, respectively (p = 0.010). The number of documented bacteremic episodes was 13 (11%) and 14 (4.7%) in the two groups, respectively (p = 0.017). Antimicrobial resistance and Clostridium difficile infections were uncommon. Transplant-related mortality was 1% in both groups. The addition of doxycycline to standard prophylaxis with ciprofloxacin seems to reduce the number of NF episodes and documented bacterial infections in patients with MM undergoing ASCT, without increasing rate of serious complications.

    Full Text Available Sebastian Werth, Kai Halbritter, Jan Beyer-WestendorfCenter for Vascular Medicine and Department of Medicine III, Division of Angiology, University Hospital “Carl Gustav Carus” Dresden, Dresden, GermanyAbstract: Over the last 15 years, low-molecular-weight heparins (LMWHs have been accepted as the “gold standard” for pharmaceutical thromboprophylaxis in patients at high risk of venous thromboembolism (VTE in most countries around the world. Patients undergoing major orthopedic surgery (MOS represent a population with high risk of VTE, which may remain asymptomatic or become symptomatic as deep vein thrombosis or pulmonary embolism. Numerous trials have investigated LMWH thromboprophylaxis in this population and demonstrated high efficacy and safety of these substances. However, LMWHs have a number of disadvantages, which limit the acceptance of patients and physicians, especially in prolonged prophylaxis up to 35 days after MOS. Consequently, new oral anticoagulants (NOACs were developed that are of synthetic origin and act as direct and very specific inhibitors of different factors in the coagulation cascade. The most developed NOACs are dabigatran, rivaroxaban, and apixaban, all of which are approved for thromboprophylaxis in MOS in a number of countries around the world. This review is focused on the pharmacological characteristics of apixaban in comparison with other NOACs, on the impact of NOAC on VTE prophylaxis in daily care, and on the management of specific situations such as bleeding complications during NOAC therapy.Keywords: major orthopedic surgery, apixaban, dabigatran, edoxaban, rivaroxaban, deep vein thrombosis, venous thromboembolism, VTE prophylaxis

    To estimate the proportion of group B streptococci (GBS)-colonized women with a reported penicillin allergy without anaphylaxis receiving appropriate intrapartum antibiotic prophylaxis. We performed a retrospective cohort study of GBS-colonized, penicillin-allergic women delivering at term receiving intrapartum antibiotic prophylaxis during labor. Scheduled cesarean deliveries were excluded. The primary outcome was the proportion of women who received appropriate antibiotic coverage, defined as penicillin or cefazolin. Secondary outcomes included neonatal outcomes such as Apgar score, blood draws, antibiotic use, length of hospital stay, and composite morbidity. Of 165 women reporting a penicillin allergy without anaphylaxis, 73 (44.2%) received an appropriate antibiotic and 92 (55.8%) received an inappropriate antibiotic. Of those receiving an inappropriate antibiotic, 56 (60.9%) were given clindamycin, 1 (1.1%) erythromycin, and 35 (38.0%) vancomycin. Women reporting rash as a penicillin reaction were more likely to receive cefazolin than another antibiotic (44 [60.3%] compared with 24 [26.1%], respectively; Ppenicillin without anaphylaxis received an antibiotic other than penicillin or cefazolin as prophylaxis, indicating poor adherence to national guidelines.

    First generation cephalosporins are commonly used as antibiotic prophylaxis prior to surgery. Patients labeled as penicillin-allergic are often precluded from receiving cephalosporins because of an allergic cross-reactivity. The aims of this study were to evaluate the clinical practice for surgical prophylaxis at Nationwide Children's Hospital and to determine the incidence of adverse effects and allergic reactions when using cephalosporins in patients labeled as penicillin-allergic. A retrospective chart review was performed to identify patients who were allergic to penicillin, penicillin antibiotic family, who required surgical treatment for an existing medical condition, and received an antibiotic to prevent surgical site infection. Five hundred thirteen penicillin-allergic patients were identified, encompassing 624 surgical cases. Cephalosporins were administered in 153 cases (24.5%) with cefazolin used 83% of the time. Only one documented case of nonanaphylactic reaction was reported. Clindamycin was the most common cephalosporin substitute (n=387), and the reported adverse reaction rate was 1.5%. No cases of anaphylaxis were documented. Our data suggest that the administration of cephalosporins for surgical prophylaxis following induction of anesthesia in a patient with a known or reported penicillin-allergy appears appropriate and results in a lower adverse event rate that when clindamycin is administered.

    Surgical site infection (SSI) continues to be a challenge in colorectal surgery. Over the years, various modalities have been used in an attempt to reduce SSI risk in elective colorectal surgery, which include mechanical bowel preparation before surgery, oral antibiotics and intravenous antibiotic prophylaxis at induction of surgery. Even though IV antibiotics have become standard practice, there has been a debate on the exact role of oral antibiotics. The primary aim was to identify the role of oral antibiotics in reduction of SSI in elective colorectal surgery. The secondary aim was to explore any potential benefit in the use of mechanical bowel preparation (MBP) in relation to SSI in elective colorectal surgery. Medline, Embase and the Cochrane Library were searched. Any randomised controlled trials (RCTs) or cohort studies after 1980, which investigated the effectiveness of oral antibiotic prophylaxis and/or MBP in preventing SSIs in elective colorectal surgery were included. Twenty-three RCTs and eight cohorts were included. The results indicate a statistically significant advantage in preventing SSIs with the combined usage of oral and systemic antibiotic prophylaxis. Furthermore, our analysis of the cohort studies shows no benefits in the use of MBP in prevention of SSIs. The addition of oral antibiotics to systemic antibiotics could potentially reduce the risk of SSIs in elective colorectal surgery. Additionally, MBP does not seem to provide a clear benefit with regard to SSI prevention.

  17. Antibiotic prophylaxis in orthopedic surgeries: the results of an implemented protocol

    Raquel Queiroz

    Full Text Available Though the basic principles of antibiotic prophylaxis have been well established, there is still considerable incorrect usage, including how much is prescribed and especially in the duration of treatment, which is generally superior to what is indicated. The adequate use of these drugs contributes towards decreasing the time of internment of the patient, prevents surgical site infection (SSI, decreasing the development of resistant microorganisms, and towards reduced costs for the hospital pharmacy. A protocol for the use of antibiotic prophylaxis in the Orthopedics and Traumatology Service of the Hospital do Servidor Público Estadual de São Paulo was developed. The objectives of the study were to promote rational antibiotic surgical prophylaxis, through the implantation of a protocol for the use of these drugs in a surgical unit, with the direct contribution of a druggist in collaboration with the Infection Control Committee, to evaluate the adhesion of the health team to the protocol during three distinct periods (daily pre-protocol, early post-protocol and late post-protocol and to define the consumption of antimicrobials used, measured as daily defined dose.

    Full Text Available Background: Migraine is a chronic and disabling disorder. Treatment of migraine often comprises of symptomatic (abortive and preventive (prophylactic treatment. The current drugs used in migraine prophylaxis include antidepressant drugs (Serotonin Reuptake Inhibitors, Tricyclic antidepressants, and anti-epileptic drugs (valproate, gabapentin, etc. Objective: The objective of our study was to assess the efficacy and tolerability of levetiracetam in adult migraine prophylaxis, compared to valproate and placebo. Materials and Methods: We conducted a prospective, randomized, placebo-controlled study. A total of 85 patients were randomized to receive levetiracetam 500 mg/d (n = 27, valproate 500 mg/d (n = 32 or placebo (n = 26. The patients were evaluated for treatment efficacy after 6 months. Efficacy was assessed as a more than 50% decrease in headache frequency. Results: In levetiracetam group, 17 (63.0% patients experienced a more than 50% decrease in headache frequency, while this efficacy number was 21 (65.6% for valproate group and 4 (15.4% for placebo group. The difference was not statistically significant between levetiracetam and valproate, while it was significant when comparing either levetiracetam or valproate to placebo. Conclusion: Compared to placebo, levetiracetam offers improvement in headache frequency in patients with migraine. The efficacy of levetiracetam in migraine prophylaxis is comparable to currently used drugs such as valproate.

    Tenofovir disoproxil fumarate (TDF)-based pre-exposure prophylaxis is a novel HIV prevention strategy for individuals at increased sexual risk for HIV infection. For any biomedical prevention intervention, the bar for tolerating adverse effects in healthy persons is high compared to therapeutic interventions. We provide a concise summary of the clinical safety of TDF-based pre-exposure prophylaxis with focus on TDF-related effects on tolerability, kidney function, bone density, HIV resistance, sexual and reproductive health. The evidence base for this review is derived from a literature search of both randomized and observational studies evaluating efficacy and safety of TDF-based PrEP, TDF alone or in combination with emtricitabine, identified from PUBMED and EMBASE electronic databases, clinicaltrials.gov and major HIV conferences. TDF-based pre-exposure prophylaxis is a potent intervention against HIV acquisition when taken which is generally safe and well tolerated. The risk of the small, non-progressive, and reversible decline in glomerular filtration rate and bone mineral density as well as the potential selection for drug resistance associated with PrEP are outweighed, at the population level and broadly for individuals, by PrEP's substantial reduction in the risk of HIV infection.

    Global Mindsets: Exploration and Perspectives seeks to tackle a topic that is relatively new in research and practice, and is considered by many to be critical for firms seeking to conduct global business. It argues that multiple mindsets exist (across and within organizations), that they operate...... in a global context, and that they are dynamic and undergo change and action. Part of the mindset(s) may depend upon place, situation and context where individuals and organizations operate. The book will examine the notion of "mindset" is situational and dynamic, especially in a global setting, why...... it is important for future scholars and managers and how it could be conceptualized. Global Mindsets: Exploration and Perspectives is split into two major sections; the first examines where the literature currently is with respect to the knowledge in the field and what conceptual frameworks guide the thinking...

    Canada's Green Plan strategy for dealing with global warming is being implemented as a multidepartmental partnership involving all Canadians and the international community. Many of the elements of this strategy are built on an existing base of activities predating the Green Plan. Elements of the strategy include programs to limit emissions of greenhouse gases, such as initiatives to encourage more energy-efficient practices and development of alternate fuel sources; studies and policy developments to help Canadians prepare and adapt to climate change; research on the global warming phenomenon; and stimulation of international action on global warming, including obligations arising out of the Framework Convention on Climate Change. All the program elements have been approved, funded, and announced. Major achievements to date are summarized, including improvements in the Energy Efficiency Act, studies on the socioeconomic impacts of global warming, and participation in monitoring networks. Milestones associated with the remaining global warming initiatives are listed

    Chronic subdural hematoma is a commonly encountered disease in neurosurgic practice, whereas its increasing prevalence is compatible with the ageing population. Recommendations concerning postoperative thrombosis prophylaxis after burr-hole drainage of chronic subdural hematoma are lacking. The aim of this study was to analyze the correlation between recurrence of chronic subdural hematoma and postoperative application of thrombosis prophylaxis. Retrospective, consecutive sample of patients undergoing burr-hole drainage for chronic subdural hematoma over 3 years. Single, academic medical center. All patients undergoing surgical evacuation of a chronic subdural hematoma with burr-hole drainage. Exclusion: patients under the age of 18 years, who presented with an acute subdural hematoma and those who underwent a craniotomy. We compared patients receiving thrombosis prophylaxis treatment after burr-hole drainage of chronic subdural hematoma with those who were not treated. Primary outcome measure was reoperation of chronic subdural hematoma due to recurrence. Secondary outcome measures were thromboembolic and cardiovascular events, hematologic findings, morbidity, and mortality. In addition, a subanalysis comparing recurrence rate dependent on the application time of thrombosis prophylaxis ( 48 hr) was undertaken. Overall recurrence rate of chronic subdural hematoma was 12.7%. Out of the 234 analyzed patients, 135 (57.3%) received postoperative thrombosis prophylaxis (low-molecular-weight heparin) applied subcutaneously. Recurrence of chronic subdural hematoma occurred in the thrombosis prophylaxis group and control group in 12 patients (8.9%) and 17 patients (17.2%), respectively, showing no significant difference (odds ratio, 0.47 [95% CI, 0.21 - 1.04]). A subanalysis comparing recurrence rate of chronic subdural hematoma dependent on the application time of thrombosis prophylaxis ( 48 hr) showed no significant difference either (odds ratio, 2.80 [95% CI, 0

    Undiagnosed low-grade prosthetic joint infections (PJI) are recognized as an important reason for early failure of presumably aseptic revisions. Preoperatively administered antimicrobial prophylaxis reduces the incidence of PJI but it may reduce the sensitivity of microbiologic periprosthetic tissue cultures and consequently increase the incidence of undiagnosed septic prosthetic joint failures, which can lead to catastrophic serial revisions. We wished to determine whether administration of preoperative antibiotics decreases the likelihood of diagnosing PJI in patients undergoing revision hip or knee arthroplasty in whom infection is suspected. We prospectively enrolled and evaluated 40 patients (29 with THAs and 11 with TKAs) who met the following inclusion criteria: older than 18 years, with suspected PJI of unknown cause, undergoing surgical revision. After arthrotomy, three tissue samples were obtained for microbiologic analysis and diagnosis, and antimicrobial prophylaxis (cefazolin 2 g intravenously) then was administered. Later during the procedure, but before débridement and irrigation, the second set of three tissue samples was obtained from the same surgical area and was cultured. Tissue concentration of prophylactic antibiotic was verified with the second set of samples. A positive culture result was defined as one or more positive cultures (growth on agar at or before 14 days). We then compared the yield on the microbiologic cultures obtained before administration of antibiotics with the yield on the cultures obtained after antibiotics were administered. An a priori analysis was performed; with the numbers available, we had 98% power to detect a difference in diagnostic sensitivity of 33%. With the numbers available, we found no difference in the likelihood that an infection would be diagnosed between the samples obtained before and after administration of antimicrobial prophylaxis (odds ratio [OR] for positive microbial culture = 0.99; 95% CI, 0

    Atorvastatin administration to both the donors and recipients of matched related donor (MRD) allogeneic hematopoietic cell transplantation (allo-HCT) as acute graft-versus-host disease (GVHD) prophylaxis has been shown to be safe and effective. However, its efficacy as acute GVHD prophylaxis when given only to allo-HCT recipients is unknown. We conducted a phase II study to evaluate the safety and efficacy of atorvastatin-based acute GVHD prophylaxis given only to the recipients of MRD (n = 30) or matched unrelated donor (MUD) (n = 39) allo-HCT, enrolled in 2 separate cohorts. Atorvastatin (40 mg/day) was administered along with standard GVHD prophylaxis consisting of tacrolimus and methotrexate. All patients were evaluable for acute GVHD. The cumulative incidences of grade II to IV acute GVHD at day +100 in the MRD and MUD cohorts were 9.9% (95% confidence interval [CI], 0 to 20%) and 29.6% (95% CI,15.6% to 43.6%), respectively. The cumulative incidences of grade III and IV acute GVHD at day +100 in the MRD and MUD cohorts were 3.4% (95% CI, 0 to 9.7%) and 18.3% (95% CI, 6.3% to 30.4%), respectively. The corresponding rates of moderate/severe chronic GVHD at 1 year were 28.1% (95% CI, 11% to 45.2%) and 38.9% (95% CI, 20.9% to 57%), respectively. In the MRD cohort, the 1-year nonrelapse mortality, relapse rate, progression-free survival, and overall survival were 6.7% (95% CI, 0 to 15.4%), 43.3% (95% CI, 24.9% to 61.7%), 50% (95% CI, 32.1% to 67.9%), and 66.7% (95% CI, 49.8% to 83.6%), respectively. The respective figures for the MUD cohort were 10.3% (95% CI, 8% to 19.7%), 20.5% (95% CI, 7.9% to 33.1%), 69.2% (95% CI, 54.7% to 83.7%), and 79.5% (95% CI, 66.8% to 92.2%), respectively. No grade 4 toxicities attributable to atorvastatin were seen. In conclusion, the addition of atorvastatin to standard GVHD prophylaxis in only the recipients of MRD and MUD allo-HCT appears to be feasible and safe. The preliminary efficacy seen here warrants confirmation in

    To compare the rate of postoperative endophthalmitis before and after initiation of intracameral (IC) moxifloxacin for endophthalmitis prophylaxis in patients undergoing cataract surgery. Retrospective, clinical registry. All charity and private patients (116 714 eyes) who underwent cataract surgery between February 15, 2014, and April 15, 2015, at the Madurai Aravind Eye Hospital were included. Group 1 consisted of 37 777 eyes of charity patients who did not receive IC moxifloxacin, group 2 consisted of 38 160 eyes of charity patients who received IC moxifloxacin prophylaxis, and group 3 consisted of 40 777 eyes of private patients who did not receive IC moxifloxacin. The electronic health record data for each of the 3 groups were analyzed, and the postoperative endophthalmitis rates were statistically compared. The cost of endophthalmitis treatment (groups 1 and 2) and the cost of IC moxifloxacin prophylaxis (group 2) were calculated. Postoperative endophthalmitis rate before and after initiation of IC moxifloxacin endophthalmitis treatment cost. Manual, sutureless, small incision cataract surgery (M-SICS) accounted for approximately all of the 75 937 cataract surgeries in the charity population (97%), but only a minority of the 40 777 private surgeries (21% M-SICS; 79% phacoemulsification). Thirty eyes in group 1 (0.08%) and 6 eyes in group 2 (0.02%) were diagnosed with postoperative endophthalmitis (P < 0.0001). The group 3 endophthalmitis rate was 0.07% (29 eyes), which was also higher than the second group's rate (P < 0.0001). There were no adverse events attributed to IC moxifloxacin in group 2. The total cost of treating the 30 patients with endophthalmitis in group 1 was virtually identical to the total combined cost in group 2 of routine IC moxifloxacin prophylaxis and treatment of the 6 endophthalmitis cases. Routine IC moxifloxacin prophylaxis achieved a highly significant, 4-fold reduction in postoperative endophthalmitis in patients undergoing M

    Sustained elimination of leprosy as a global health concern likely requires a vaccine. The current standard, BCG, confers only partial protection and precipitates paucibacillary (PB) disease in some instances. When injected into mice with the T helper 1 (Th1)-biasing adjuvant formulation Glucopyranosyl Lipid Adjuvant in stable emulsion (GLA-SE), a cocktail of three prioritized antigens (ML2055, ML2380 and ML2028) reduced M. leprae infection levels. Recognition and protective efficacy of a single chimeric fusion protein incorporating these antigens, LEP-F1, was confirmed in similar experiments. The impact of post-exposure immunization was then assessed in nine-banded armadillos that demonstrate a functional recapitulation of leprosy. Armadillos were infected with M. leprae 1 month before the initiation of post-exposure prophylaxis. While BCG precipitated motor nerve conduction abnormalities more rapidly and severely than observed for control infected armadillos, motor nerve injury in armadillos treated three times, at monthly intervals with LepVax was appreciably delayed. Biopsy of cutaneous nerves indicated that epidermal nerve fiber density was not significantly altered in M. leprae -infected animals although Remak Schwann cells of the cutaneous nerves in the distal leg were denser in the infected armadillos. Importantly, LepVax immunization did not exacerbate cutaneous nerve involvement due to M. leprae infection, indicating its safe use. There was no intraneural inflammation but a reduction of intra axonal edema suggested that LepVax treatment might restore some early sensory axonal function. These data indicate that post-exposure prophylaxis with LepVax not only appears safe but, unlike BCG, alleviates and delays the neurologic disruptions caused by M. leprae infection.

    Pneumocystis pneumonia (PCP) is a disease affecting immunocompromised patients. PCP among these patients is associated with significant morbidity and mortality. To assess the effectiveness of PCP prophylaxis among non-HIV immunocompromised patients; and to define the type of immunocompromised patient for whom evidence suggests a benefit for PCP prophylaxis. Electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE and EMBASE (to March 2014), LILACS (to March 2014), relevant conference proceedings; and references of identified trials. Randomised controlled trials (RCTs) or quasi-RCTs comparing prophylaxis with an antibiotic effective against PCP versus placebo, no intervention, or antibiotic(s) with no activity against PCP; and trials comparing different antibiotics effective against PCP among immunocompromised non-HIV patients. We only included trials in which Pneumocystis infections were available as an outcome. Two review authors independently assessed risk of bias in each trial and extracted data from the included trials. We contacted authors of the included trials to obtain missing data. The primary outcome was documented PCP infections. Risk ratios (RR) with 95% confidence intervals (CI) were estimated and pooled using the random-effects model. Thirteen trials performed between the years 1974 and 2008 were included, involving 1412 patients. Four trials included 520 children with acute lymphoblastic leukemia and the remaining trials included adults with acute leukemia, solid organ transplantation or autologous bone marrow transplantation. Compared to no treatment or treatment with fluoroquinolones (inactive against Pneumocystis), there was an 85% reduction in the occurrence of PCP in patients receiving prophylaxis with trimethoprim/sulfamethoxazole, RR of 0.15 (95% CI 0.04 to 0.62; 10 trials, 1000 patients). The evidence was graded as moderate due to possible risk of bias. PCP

    Parastomal hernia (PSH) is common after stoma formation. Studies have reported that mesh prophylaxis reduces PSH, but there are no cost-effectiveness data. Our objective was to determine the cost effectiveness of mesh prophylaxis vs no prophylaxis to prevent PSH in patients undergoing abdominoperineal resection with permanent colostomy for rectal cancer. Using a cohort Markov model, we modeled the costs and effectiveness of mesh prophylaxis vs no prophylaxis at the index operation in a cohort of 60-year-old patients undergoing abdominoperineal resection for rectal cancer during a time horizon of 5 years. Costs were expressed in 2012 Canadian dollars (CAD$) and effectiveness in quality-adjusted life years. Deterministic and probabilistic sensitivity analyses were performed. In patients with stage I to III rectal cancer, prophylactic mesh was dominant (less costly and more effective) compared with no mesh. In patients with stage IV disease, mesh prophylaxis was associated with higher cost (CAD$495 more) and minimally increased effectiveness (0.05 additional quality-adjusted life years), resulting in an incremental cost-effectiveness ratio of CAD$10,818 per quality-adjusted life year. On sensitivity analyses, the decision was sensitive to the probability of mesh infection and the cost of the mesh, and method of diagnosing PSH. In patients undergoing abdominoperineal resection with permanent colostomy for rectal cancer, mesh prophylaxis might be the less costly and more effective strategy compared with no mesh to prevent PSH in patients with stage I to III disease, and might be cost effective in patients with stage IV disease.

    HIV pre-exposure prophylaxis (PrEP) is not approved in Switzerland and therefore must be paid for by the users themselves. We conducted a survey to find out whether men who have sex with men (MSM) in Switzerland are already taking PrEP, or are considering using it, and whether it is being taken under medical supervision or not. Grindr® is a geosocial networking app for MSM. Between 5 and 24 January 2017, users of the app who were located in Switzerland by a global positioning system (GPS) were asked to participate in a ten-question survey on PrEP use. Of the 2455 people who took part in the survey, 1893 were included in the analysis. Eighty-two participants (4.3%) reported that they were currently taking PrEP, 64 of whom (78%) said that they were under medical supervision. Seven PrEP users (9%) declared that they had not taken an HIV test within the previous 12 months. Nine hundred and forty-four (49.9%) were considering taking PrEP in the next 6 months, and 1474 (77.9%) were considering taking it at some point in the future. In an online survey carried out among sexually active MSM in Switzerland, only a minority of the individuals approached responded that they were currently using PrEP. However, the majority of participants were considering taking PrEP in the future. We identified a substantial proportion of PrEP users taking PrEP outside a medical setting. Hence, a national programme facilitating access to medical care and providing PrEP is urgently needed. © 2017 The Authors.

    For women at risk of HIV-1, effective contraception and effective HIV-1 prevention are global priorities. In a clinical trial of pre-exposure prophylaxis (PrEP) for HIV-1 prevention in HIV-1-serodiscordant couples, we estimated the effectiveness of hormonal contraceptives (oral contraceptive pills, injectable depot medroxyprogesterone acetate, and hormonal implants) for pregnancy prevention relative to no contraception among 1785 HIV-1-uninfected women followed up to 36 months. We compared the effectiveness of each method among women assigned PrEP versus placebo. Contraception was not required for participation, but was offered on-site and was recorded monthly; incident pregnancy was determined by monthly urine testing. For women using no contraception, overall pregnancy incidence was 15.4% per year. Women reporting oral contraceptive use had comparable pregnancy incidence to women using no contraception, and this lack of contraceptive effectiveness was similar for those assigned PrEP and placebo (17.7 and 10.0% incidence per year, respectively; P-value for difference in effect by PrEP use = 0.24). Women reporting injectable contraception had reduced pregnancy incidence compared to those reporting no contraception, which did not differ by arm (PrEP 5.1%, placebo 5.3% per year; P-value for difference = 0.47). Contraceptive effectiveness was highest among women using implants (pregnancy incidence <1% per year in both arms). PrEP had no adverse impact on hormonal contraceptive effectiveness for pregnancy prevention. As seen previously in similar populations, women reporting contraceptive pill use had little protection from pregnancy, possibly due to poor adherence. Injectable or implantable hormonal contraception and PrEP provide effective prevention for pregnancy and HIV-1.

    As HIV prevalence climbs globally, including more than 50,000 new infections per year in the United States, we need effective HIV prevention strategies. The use of antiretrovirals for pre-exposure prophylaxis (known as “PrEP”) among high-risk HIV-uninfected persons is emerging as one such strategy. Randomized controlled trials have demonstrated that once daily oral PrEP decreased HIV incidence among at-risk MSM and African heterosexuals, including HIV serodiscordant couples. An additional randomized control trial of a pericoital topical application of antiretroviral microbicide gel reduced HIV incidence among at-risk heterosexual South African women. Two other studies in African women did not demonstrate the efficacy of oral or topical PrEP, raising concerns about adherence patterns and efficacy in this population. The FDA Antiretroviral Advisory Panel reviewed these studies and additional data in May 2012 and recommended the approval of oral tenofovir-emtricitabine for PrEP in high-risk populations. Patients may seek PrEP from their primary care providers and those on PrEP require monitoring. Thus, primary care providers should become familiar with PrEP. This review outlines the current state of knowledge about PrEP as it pertains to primary care including identification of individuals likely to benefit from PrEP, counseling to maximize adherence and minimize potential increases in risky behavior, and monitoring for potential drug toxicities, HIV acquisition, and antiretroviral drug resistance. Issues related to cost and insurance coverage are also discussed. Recent data suggest that PrEP, in conjunction with other prevention strategies, holds promise in helping to curtail the HIV epidemic.
