    We conducted a retrospective analysis of data from a prospective nPEP (non-Occupational Post Exposure Prophylaxis) registry based on patients consulting at one academic Emergency department located in Brussels, Belgium. We review here 1,357 cases consulting from January 2011 to December 2013.The objective of the study is to determine whether emergency physicians prescribe nPEP according to national guideline with support from IDS (infectious disease specialists). As this intervention has a hi...

    Full Text Available Abstract Background In May 2005, the Western Australian Department of Health (WA Health developed a communication strategy to improve the awareness and appropriate use of non-occupational post-exposure prophylaxis (nPEP in WA. The communication strategy included the development of an nPEP information pamphlet, the establishment of a 24 hour nPEP phone line and the distribution of the WA Health nPEP guidelines to health professionals. The communication strategy was aimed at gay men, people in sero-discordant relationships, people living with HIV, injecting drug users and health care providers with patients from these populations. This evaluation aimed to assess the awareness and appropriate use of nPEP in WA before and after the commencement of the nPEP communication strategy. Methods A program logic method was used to identify the immediate (short-term and ultimate (long-term outcomes of the communication strategy. The achievement of these outcomes was evaluated using data from website statistics, a survey of ‘sexuality sensitive’ doctors, statistics published in Perth Gay Community Periodic Surveys (PGCPS and data from the WA nPEP database. A χ2 test for trend was conducted to identify any significant changes in the ultimate outcome indicators pre- and post-strategy. Results nPEP awareness among gay men in the PGCPS initially increased from 17.2% in 2002 to 54.9% in 2008, then decreased to 39.9% in 2010. After the commencement of the communication strategy, the proportion of nPEP prescriptions meeting the eligibility criteria for nPEP significantly increased (61.2% in 2002-2005 to 90.0% in 2008-2010 (p  Conclusions Since the introduction of the nPEP communication strategy, the delivery and appropriate use of nPEP have significantly improved in WA. In the 2008-2010 period, an improvement in HIV testing of nPEP recipients at three month follow-up was reported for the first time in WA. However, there is a need for ongoing activities to

    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.

    2016-02-01

    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.

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.

  8. Parsonage-Turner syndrome following post-exposure prophylaxis

    Science.gov (United States)

    2014-01-01

    Background The ‘Parsonage-Turner syndrome’ (PTS) is a rare but distinct disorder with an abrupt onset of shoulder pain, followed by weakness and atrophy of the upper extremity musculature, and a slow recovery requiring months to years. To our best knowledge, this is the first case describing symptoms and signs of PTS following the administration of a post-exposure prophylaxis (PEP) regimen against possible human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infection. Case presentation A 25-year-old Caucasian man presented with pain and unilateral scapular winging following PEP against possible HIV and HBV infection. Although atrophy and weakness were observed for the right supraspinatus muscle, a full range of motion was achievable. Neurological examination, plain radiography of the right shoulder and electromyography showed no additional abnormalities. The patient was diagnosed with post-vaccination PTS and treated non-operatively. During the following 15 months the scapular winging receded and full muscle strength was regained. Conclusion Parsonage-Turner syndrome is a rare clinical diagnosis. The precise pathophysiological mechanism of PTS remains unclear, but it seems to involve an interaction between genetic predisposition, mechanical vulnerability and an autoimmune trigger. An immunological event, such as – in this case – a vaccination as part of PEP treatment, can trigger the onset of PTS. The clinical presentation is distinctive with acute severe pain followed by patchy paresis, atrophy and sensory symptoms that persist for months to years. No currently available tests can provide a definite confirmation or exclusion of PTS. Routine blood examination, electromyography (EMG), and computed tomography (CT) or magnetic resonance imaging (MRI) serve mainly to exclude other disorders. The recovery can be quite lengthy, non-operative treatment is the accepted practice. Supplementary administration of oral prednisolone could shorten the

    Post-exposure prophylaxis (PEP) can be a secondary measure to prevent infection by human immunodeficiency virus (HIV) when primary prevention has failed. PEP is advised for people with sporadic and exceptional risk exposure to HIV. This consensus document about occupational and non-occupational PEP recommendations aims to be a technical document for healthcare professionals. Its main objective is to facilitate the appropriate use of PEP. To this end, some recommendations have been established to assess the risk of transmission in different types of exposure, situations where PEP should be recommended, special circumstances to take into account, antiretroviral (ARV) guidelines including start and end of the treatment, early monitoring of tolerance and adherence to the treatment, subsequent monitoring of people exposed, independently of having received PEP or not, and need of psychological support. This document is intended for all professionals who work in clinical practice in the field of HIV infection.

  10. Evaluation of hepatitis A vaccine in post-exposure prophylaxis, The Netherlands, 2004-2012.

    Directory of Open Access Journals (Sweden)

    Jane Whelan

    Full Text Available BACKGROUND: The secondary attack rate of hepatitis A virus (HAV among contacts of cases is up to 50%. Historically, contacts were offered immunoglobulin (IG, a human derived blood product as post-exposure prophylaxis (PEP. Amid safety concerns about IG, HAV vaccine is increasingly recommended instead. Public health authorities' recommendations differ, particularly for healthy contacts ≥40 years old, where vaccine efficacy data is limited. We evaluated routine use of HAV vaccine as an alternative to immunoglobulin in PEP, in those considered at low risk of severe infection in the Netherlands. METHODS: Household contacts of acute HAV cases notified in Amsterdam (2004-2012 were invited ≤14 days post-exposure, for baseline anti-HAV testing and PEP according to national guidelines: immunoglobulin if at risk of severe infection, or hepatitis A vaccine if healthy and at low risk (aged 40 years of age. In healthy contacts vaccinated per-protocol ≤8 days post-exposure, RR(ref. ≤15 years of secondary infection in those >40 years was 12.0 (95%CI:1.3-106.7. CONCLUSIONS: Timely administration of HAV vaccine in PEP was feasible and the secondary attack rate was low in those 40 years of age and those vulnerable to severe disease.

    Full Text Available Background: Rabies is a fatal infectious disease and rabies post-exposure prophylaxis is the method of choice for prevention of human rabies.Case series: We report rabies antibody levels in cord blood and also in serum of pregnant women who were bitten by suspected animals to rabies and were immunized by purified Vero cell rabies vaccine (PVRV and Human Rabies immunoglobulin (HRIG serum. During the years of 2007-2010, six pregnant women by the age range of 22-35 years were admitted in treatment and prevention of rabies center in Pasture institute of Iran, in Tehran. Among them two cases were at first trimester, one at second trimester and three at third trimester of conception. The interval between biting with delivery was 5-265 days (mean 121 days.Conclusion: Results of immunoglobulin illustrate that levels of rabies antibody in maternal sera with the fetus are not equal and uniform but it is proved that baby will find efficient immunity as well with minimum protective level of 0.5 IU/ml in all cases except a newborn whom had been born just 5 days after the mother’s immunization and in a shorter time than the appropriate immunization of the mother who had received her second vaccination courses.

    Full Text Available Abstract Background Rabies is a major public-health problem in developing countries such as China. Although the recent re-emergence of human rabies in China was noted in several epidemiological studies, little attention was paid to the reasons behind this phenomenon paralleling the findings of the previous reports. The purpose of this study is thus first to characterize the current trends of human rabies in China from 1990 to 2007, and then to define better recommendations for improving the post-exposure prophylaxis (PEP schedules delivered to rabies patients. Methods The most updated epidemiological data for 22527 human rabies cases from January 1990 to July 2007, retrieved from the surveillance database of reportable diseases managed by the Ministry of Health of China, were analysed. To investigate the efficiency for the post-exposure treatment of rabies, the details of 244 rabies patients, including their anti-rabies treatment of injuries or related incidents, were ascertained in Guangdong provincial jurisdiction. The risk factors to which the patients were predisposed or the regimens given to 80 patients who received any type of PEP were analysed to identify the reasons for the PEP failures. Results The results from analysis of the large number of human rabies cases showed that rabies in China was largely under control during the period 1990–1996. However, there has been a large jump in the number of reported rabies cases since 2001 up to a new peak (with an incidence rate of 0.20 per 100000 people that was reached in 2004, and where the level has remained until present. Then, we analysed the PEP in 244 rabies cases collected in the Guangdong province in 2003 and 2004, and found that 67.2% of the patients did not seek medical services or did not receive any PEP. Further analysis of PEP for the 80 rabies patients who received any type of PEP indicated that almost all of the patients did not receive proper or timely treatment on the wounds

  13. Rabies exposures, post-exposure prophylaxis and deaths in a region of endemic canine rabies.

    Full Text Available Thousands of human deaths from rabies occur annually despite the availability of effective vaccines following exposure, and for disease control in the animal reservoir. Our aim was to assess risk factors associated with exposure and to determine why human deaths from endemic canine rabies still occur.Contact tracing was used to gather data on rabies exposures, post-exposure prophylaxis (PEP delivered and deaths in two rural districts in northwestern Tanzania from 2002 to 2006. Data on risk factors and the propensity to seek and complete courses of PEP was collected using questionnaires. Exposures varied from 6-141/100,000 per year. Risk of exposure to rabies was greater in an area with agropastoralist communities (and larger domestic dog populations than an area with pastoralist communities. Children were at greater risk than adults of being exposed to rabies and of developing clinical signs. PEP dramatically reduced the risk of developing rabies (odds ratio [OR] 17.33, 95% confidence interval [CI] 6.39-60.83 and when PEP was not delivered the risks were higher in the pastoralist than the agro-pastoralist area (OR 6.12, 95% CI 2.60-14.58. Low socioeconomic class and distance to medical facilities lengthened delays before PEP delivery. Over 20% of rabies-exposed individuals did not seek medical treatment and were not documented in official records and <65% received PEP. Animal bite injury records were an accurate indicator of rabies exposure incidence.Insufficient knowledge about rabies dangers and prevention, particularly prompt PEP, but also wound management, was the main cause of rabies deaths. Education, particularly in poor and marginalized communities, but also for medical and veterinary workers, would prevent future deaths.

    Full Text Available Rabies is a uniformly fatal disease, but preventable by timely and correct use of post exposure prophylaxis (PEP. Unfortunately, many health care facilities in Pakistan do not carry modern life-saving vaccines and rabies immunoglobulin (RIG, assuming them to be prohibitively expensive and unsafe. Consequently, Emergency Department (ED health care professionals remain untrained in its application and refer patients out to other hospitals. The conventional Essen regimen requires five vials of cell culture vaccine (CCV per patient, whereas Thai Red Cross intradermal (TRC-id regimen requires only one vial per patient, and gives equal seroconversion as compared with Essen regimen.This study documents the cost savings in using the Thai Red Cross intradermal regimen with cell culture vaccine instead of the customary 5-dose Essen intramuscular regimen for eligible bite victims. All patients presenting to the Indus Hospital ED between July 2013 to June 2014 with animal bites received WHO recommended PEP. WHO Category 2 bites received intradermal vaccine alone, while Category 3 victims received vaccine plus wound infiltration with Equine RIG. Patients were counseled, and subsequent doses of the vaccine administered on days 3, 7 and 28. Throughput of cases, consumption utilization of vaccine and ERIG and the cost per patient were recorded.Government hospitals in Pakistan are generally underfinanced and cannot afford treatment of the enormous burden of dog bite victims. Hence, patients are either not treated at all, or asked to purchase their own vaccine, which most cannot afford, resulting in neglect and high incidence of rabies deaths. TRC-id regimen reduced the cost of vaccine to 1/5th of Essen regimen and is strongly recommended for institutions with large throughput. Training ED staff would save lives through a safe, effective and affordable technique.

  15. Development of a mouse monoclonal antibody cocktail for post-exposure rabies prophylaxis in humans.

    Directory of Open Access Journals (Sweden)

    Thomas Müller

    Full Text Available As the demand for rabies post-exposure prophylaxis (PEP treatments has increased exponentially in recent years, the limited supply of human and equine rabies immunoglobulin (HRIG and ERIG has failed to provide the required passive immune component in PEP in countries where canine rabies is endemic. Replacement of HRIG and ERIG with a potentially cheaper and efficacious alternative biological for treatment of rabies in humans, therefore, remains a high priority. In this study, we set out to assess a mouse monoclonal antibody (MoMAb cocktail with the ultimate goal to develop a product at the lowest possible cost that can be used in developing countries as a replacement for RIG in PEP. Five MoMAbs, E559.9.14, 1112-1, 62-71-3, M727-5-1, and M777-16-3, were selected from available panels based on stringent criteria, such as biological activity, neutralizing potency, binding specificity, spectrum of neutralization of lyssaviruses, and history of each hybridoma. Four of these MoMAbs recognize epitopes in antigenic site II and one recognizes an epitope in antigenic site III on the rabies virus (RABV glycoprotein, as determined by nucleotide sequence analysis of the glycoprotein gene of unique MoMAb neutralization-escape mutants. The MoMAbs were produced under Good Laboratory Practice (GLP conditions. Unique combinations (cocktails were prepared, using different concentrations of the MoMAbs that were capable of targeting non-overlapping epitopes of antigenic sites II and III. Blind in vitro efficacy studies showed the MoMab cocktails neutralized a broad spectrum of lyssaviruses except for lyssaviruses belonging to phylogroups II and III. In vivo, MoMAb cocktails resulted in protection as a component of PEP that was comparable to HRIG. In conclusion, all three novel combinations of MoMAbs were shown to have equal efficacy to HRIG and therefore could be considered a potentially less expensive alternative biological agent for use in PEP and prevention of

    Full Text Available Background: Nurses caring for people living with HIV (PLWH are at higher risk of exposure to the human immunodeficiency virus (HIV by needle sticks, cuts, getting body fluids in their eyes or mouth and skin when bruised or affected by dermatitis.Objectives: To determine knowledge, insight and uptake of occupational post-exposure prophylaxis (OPEP amongst nurses caring for PLWH.Method: A cross-sectional descriptive design was used in this study. Stratified random sampling was used to sample 240 nurses. The study was conducted in a regional hospital in Limpopo province. Both parametric and non-parametric statistics were employed to analyse data.Results: A total of 233 nurses participated in the study. Sixty per cent (n = 138 of all nurses had a situation at work when they thought that they were infected by HIV and 100 (43% nurses had experienced the situation once or more in the past 12 month. Approximately 40% did not know what PEP (post-exposure prophylaxis is, and 22% did not know or were not sure if it was available in the hospital. Only few participants (n = 68, 29% had sought PEP and most (n = 37, 54% of them did not receive PEP when they needed it. There was a significant association between the knowledge and availability of PEP (r = 0.622.Conclusion: The study recommend an urgent need for policy makers in the health sector to put in place policies, guidelines and programmes that will rapidly scale up PEP services in health care settings, so that preventable occupationally acquired HIV infection can be minimised amongst nurses.Keywords: Post-Exposure Prophylaxis; Nurses; HIV, Occupational Exposure; PLWH

    Rabies remains a serious public health problem in many developing countries. The diagnosis is easy when a non-immunised patient presents with hydrophobia and hypersalivation after a bite by a known rabid animal but more difficult when a patient presents atypical symptoms after having received rabies postexposure prophylaxis. Rabies postexposure prophylaxis failure is rare. We report a case of a 6-year-old boy who presented febrile seizure with agitation and cerebellar signs, without hydrophobia or hypersalivation, 17 days after a dog bite. Despite four doses of rabies vaccine and immunoglobulin, he died. Diagnostic confirmation of rabies encephalitis was made in post mortem on brain biopsies by fluorescent antibody technique.

    Post-exposure prophylaxis (PEP) for leprosy is administered as one single dose of rifampicin (SDR) to the contacts of newly diagnosed leprosy patients. SDR reduces the risk of developing leprosy among contacts by around 60 % in the first 2-3 years after receiving SDR. In countries where SDR is currently being implemented under routine programme conditions in defined areas, questions were raised by health authorities and professional bodies about the possible risk of inducing rifampicin resistance among the M. tuberculosis strains circulating in these areas. This issue has not been addressed in scientific literature to date. To produce an authoritative consensus statement about the risk that SDR would induce rifampicin-resistant tuberculosis, a meeting was convened with tuberculosis (TB) and leprosy experts. The experts carefully reviewed and discussed the available evidence regarding the mechanisms and risk factors for the development of (multi) drug-resistance in M. tuberculosis with a view to the special situation of the use of SDR as PEP for leprosy. They concluded that SDR given to contacts of leprosy patients, in the absence of symptoms of active TB, poses a negligible risk of generating resistance in M. tuberculosis in individuals and at the population level. Thus, the benefits of SDR prophylaxis in reducing the risk of developing leprosy in contacts of new leprosy patients far outweigh the risks of generating drug resistance in M. tuberculosis.

    Full Text Available Objectives: To assess the knowledge of interns on standard precautions and post-exposure prophylaxis for HIV, and identify the gap between knowledge and practice relating to standard precautions, as well as determining the perceived barriers against adherence to standard precautions.Methods: The study was conducted on 130 interns of 2010-11 batch from a government-run medical college in Kolkata, India. All participants completed a self-administered questionnaire with items relating to basic components of standard precautions and post-exposure prophylaxis for HIV. The questionnaire also included open ended questions relating to reasons for non-adherence to the practice of standard precautions along with additional space for specific comments, if any.Results: Poor adherence in the use of personal protective equipment, hand washing, safe handling and disposal of needles and sharp objects were found to be among the practices for which the interns expressed correct knowledge. While the main reasons for non-adherence were found to be clumsiness in handling needles, wearing gloves, feeling uncomfortable when wearing aprons, impracticality of regular hand-washing and non-availability of equipment. Although the majority of the respondents (84.6% expressed awareness of washing sites of injured with soap and water, approximately 32.3% did not know that antiseptics could cause more damage. Also, only 63.8% expressed awareness of reporting any incidence of occupational exposure, while knowledge on post-exposure prophylaxis regimens was generally found to be poor.Conclusion: The considerable gap between knowledge and practice of standard precautions and inadequate knowledge of post-exposure prophylaxis emphasizes the need for continuous onsite training of interns with supportive supervision and monitoring of their activities.

  2. IMMUNE RESPONSE AND COST ANALYSIS OF INTRADERMAL RABIES VACCINATION FOR POST-EXPOSURE PROPHYLAXIS REGIMEN IN HUMAN

    2014-01-01

    Full Text Available BackgroundThe outbreak of rabies in human in Bali-Indonesia is causing an extraordinary pressure for the government in providing adequate doses of anti-rabies vaccine for post-exposure prophylaxis (PEP. Here, we directly compare the immune response and benefit of the intradermal (ID protocol for rabies vaccine delivery with the intramuscular (IM route. Methods: Sixty health workers who were willing to participate in this study have been randomly selected and grouped into ID, IM, and control groups, each with 20 volunteers. The Thai Red Cross ID- and Zangreb IM-protocols have been applied to the respective group. The sera of the volunteers were collected at day 0, week 1, week 3, week 4, month 3, month 6, month 9, and month 12 after the first vaccination. Anti-rabies virus IgG was detected using PlateliaTM Rabies II Kit (Bio-Rad. Results: Anti-rabies IgG could be detected in the ID-group at one week. The ID-vaccine delivery induced a slightly higher maximum antibody titer compared to IM, though not statistically significant (p>0.05. ID vaccination caused less adverse reactions and produces longer lasting protective immune response.  Cost minimization analysis (CMA on the provincial and national PEP data in 2009-2011 shows that the ID-delivery will reduce the total cost for a completed regimen by USD 28.5, and would have saved the Indonesian government budget approximately USD 3.6 and 4.3 million for complete regimens in Bali and Indonesia, respectively. Conclusion: The ID administration of anti-rabies vaccine induces a similar immune response compared to that of intramuscular injection. It also produces longer lasting protective immune response. It offers additional advantages of potential net cost savings as well as decreasing the pressure on vaccine availability due to the high number of dog bite cases.

    The Soweto Men's Study (2008), demonstrated an overall HIV prevalence rate of 13.2 %, with 10.1 % among straight-identified Men-who-have-sex-with-men (MSM), 6.4 % among bisexual-identified MSM and 33.9 % among gay-identified MSM. Behavioral interventions are imperative, but insufficient to prevent new HIV infections. Biomedical prevention of HIV offers a variety of combination prevention tools, including Post-exposure prophylaxis (PEP). PEP studies amongst MSM have been conducted in Amsterdam, Brazil and San Francisco, but never before in Africa. A cross-sectional, Internet-based survey was initiated to measure knowledge, attitudes and beliefs regarding PEP among South African MSM. Recruitment commenced in June 2014 and ran until October 2015. Participants were recruited through banner advertisements on Facebook.com and mambaonline.com, advertisements in the local gay media and at Health4Men (H4M) MSM-targeted clinics. Outreach workers distributed flyers advertising the study in their local communities. The survey was also made available on a computer at the H4M clinics in Cape Town and Johannesburg to reach MSM who may not have Internet access. A total of 408 men completed the survey. The majority of these men were under the age of 40, identified as gay/homosexual and were employed; 51 % (208/408) self-identified as black or of mixed race. In multivariate analysis participants who identified as gay had greater odds of having previously heard of PEP (AOR 1.91, 95 % CI 1.04, 3.51; p = 0.036), as did those who reported their HIV status as positive (AOR 2.59, 95 % CI 1.47, 4.45; p = 0.001). Participants with medical insurance had greater odds of having used PEP previously (AOR 2.67, 95 % CI 1.11, 6.43; p = 0.029). Bivariate analysis showed that condomless sex in the past 6 months was not significantly associated with PEP knowledge (p = 0.75) or uptake (p = 0.56) of PEP. Our findings suggest a lack of PEP knowledge and uptake among non-gay identified

    To investigate changing clinical practice with regard to antiretroviral post-exposure prophylaxis (PEP) and factors associated with the use of combination prophylaxis in infants born to HIV-infected women in the UK and Ireland. Surveillance of obstetric and paediatric HIV infection in the UK and Ireland is conducted through the National Study of HIV in Pregnancy and Childhood. Infants born to HIV-infected women between 2001 and 2008 were included in the study. Ninety-nine per cent of infants (8155 of 8205) received antiretroviral prophylaxis; 86% of those with information on type of prophylaxis (n=8050) received single, 3% dual and 11% triple drug prophylaxis. Among those who received prophylaxis, use of triple prophylaxis increased significantly between 2001-2004 and 2005-2008, from 9% (297 of 3243) to 13% (624 of 4807) overall (P<0.001); from 43% (41 of 95) to 71% (45 of 63) in infants born to untreated women; and from 13% (114 of 883) to 32% (344 of 1088) where mothers were viraemic despite highly active antiretroviral therapy (HAART) in pregnancy. In multivariable analysis, factors associated with receipt of triple prophylaxis included later time period, shorter duration or lack of antenatal antiretroviral therapy, receipt of antiretroviral drugs during labour, detectable maternal viral load, CD4 count<200 cells/μL in pregnancy, preterm delivery (<37 weeks) and unplanned (emergency caesarean or vaginal) delivery. Between 2001 and 2008, almost all infants born to HIV-infected women in the UK and Ireland received antiretroviral PEP, mostly with one drug. Use of triple PEP increased over time, particularly for infants whose mothers were untreated or viraemic despite HAART, in line with current guidelines. © 2011 British HIV Association.

    UK post-exposure prophylaxis (PEP) guidelines were updated by the British Association for Sexual Health and HIV (BASHH) in 2011. In 2013, we changed policy to omit day 5 PEP follow-up at 56 Dean Street as it was felt clinically unnecessary. This audit compares our performance against BASHH standards for PEP attenders during June 2012 and June 2013. We identified 162 PEP prescriptions; PEP assessment and appropriate sexually transmitted infection testing was done well. PEP completion rates and post-PEP HIV testing were lower than BASHH standards. Following omission of day 5 review, documentation that results have been checked was poor; however, attendance at follow-up was not adversely affected.

    Introduction The reported number of new leprosy patients has barely changed in recent years. Thus, additional approaches or modifications to the current standard of passive case detection are needed to interrupt leprosy transmission. Large-scale clinical trials with single dose rifampicin (SDR) given as post-exposure prophylaxis (PEP) to contacts of newly diagnosed patients with leprosy have shown a 50–60% reduction of the risk of developing leprosy over the following 2 years. To accelerate the uptake of this evidence and introduction of PEP into national leprosy programmes, data on the effectiveness, impact and feasibility of contact tracing and PEP for leprosy are required. The leprosy post-exposure prophylaxis (LPEP) programme was designed to obtain those data. Methods and analysis The LPEP programme evaluates feasibility, effectiveness and impact of PEP with SDR in pilot areas situated in several leprosy endemic countries: India, Indonesia, Myanmar, Nepal, Sri Lanka and Tanzania. Complementary sites are located in Brazil and Cambodia. From 2015 to 2018, contact persons of patients with leprosy are traced, screened for symptoms and assessed for eligibility to receive SDR. The intervention is implemented by the national leprosy programmes, tailored to local conditions and capacities, and relying on available human and material resources. It is coordinated on the ground with the help of the in-country partners of the International Federation of Anti-Leprosy Associations (ILEP). A robust data collection and reporting system is established in the pilot areas with regular monitoring and quality control, contributing to the strengthening of the national surveillance systems to become more action-oriented. Ethics and dissemination Ethical approval has been obtained from the relevant ethics committees in the countries. Results and lessons learnt from the LPEP programme will be published in peer-reviewed journals and should provide important evidence and guidance for

    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 South Africa. Adherence was high and demonstrates that adherence support is feasible from a state health clinic. Reported risk behaviors in some high-risk participants did not change over time, demonstrating the need for additional longer-term HIV preventions such as PrEP. PEP users could conceivably be transitioned from PEP to PrEP.

    Strategies to implement post exposure prophylaxis (PEP) in case of an anthrax bioterror event are needed. To increase the number of doses of vaccine available we evaluated reducing the amount of vaccine administered at each of the vaccinations, and reducing the number of doses administered. Healthy male and non-pregnant female subjects between the ages of 18 and 65 were enrolled and randomized 1:1:1:1 to one of four study arms to receive 0.5 mL (standard dose) of vaccine subcutaneously (SQ) at: (A) days 0, 14; (B) days 0 and 28; (C) days 0, 14, and 28; or (D) 0.25 mL at days 0, 14, and 28. A booster was provided on day 180. Safety was assessed after each dose. Blood was obtained on days 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 84, 100, 180, and 201 and both Toxin Neutralizing antibody and anti-PA IgG antibody measured. Almost all subjects developed some local reactions with 46-64% reported to be of moderate severity and 3.3% severe during the primary series. Vaccine groups that included a day 14 dose induced a ≥ 4 fold antibody rise in more subjects on days 21, 28, and 35 than the arm without a day 14 dose. However, schedules with a full day 28 dose induced higher peak levels of antibody that persisted longer. The half dose regimen did not induce antibody as well as the full dose study arms. Depending on the extent of the outbreak, effectiveness of antibiotics and availability of vaccine, the full dose 0, 28 or 0, 14, 28 schedules may have advantages. Copyright © 2014 Elsevier Ltd.

    Men who have sex with men (MSM) who use crystal methamphetamine (CM) are at increased risk for HIV infection. Post-exposure prophylaxis (PEP) is a useful HIV prevention strategy if individuals are able to identify high-risk exposures and seek timely care, however to date there has been limited data on the use of PEP by CM users. Retrospective cohort study of all PEP prescriptions (N=1130 prescriptions among 788 MSM) at Fenway Community Health in Boston, MA was undertaken. Multivariable models were used to assess the association between CM use during exposure (7.4% used CM during exposure) and chronically (7.4% of MSM were chronic CM users) and individual-level and event-level outcomes among MSM who used PEP at least once. Compared to those who had not used CM, MSM PEP users who used CM more frequently returned for repeat PEP (aOR 5.13, 95% CI 2.82 to 9.34) and were significantly more likely to seroconvert over the follow-up period (aHR 3.61, 95% CI 1.51 to 8.60). MSM who used CM had increased odds of unprotected anal intercourse as the source of exposure (aOR 2.12, 95% CI 1.16 to 3.87) and knowing that their partner was HIV infected (aOR 2.27, 95% CI 1.42 to 3.64). While MSM who use CM may have challenges accessing ART in general, these data highlight the fact that those who were able to access PEP subsequently remained at increased risk of HIV seroconversion. Counseling and/or substance use interventions during the PEP course should be considered for CM-using MSM. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Background In the era of highly active antiretroviral therapy (HAART),the use of antiretrovirals as post-exposure prophylaxis (PEP) was the most important strategy for preventing occupational exposure to blood or fluids containing human immunodeficiency virus (HIV).The objective of this study was to retrospectively evaluate the tolerability,safety,and side effects of a HAART regimen containing three antiretroviral drugs,consisting of zidovudine,lamivudine,and lopinavir/ ritonavir,in healthcare personnel (HCP) who experienced occupational exposure to HIV.Methods The tolerability,safety,and side effects in 26 HCPs who experienced PEP and in 27 HIV/AIDS patients with HAART regimen,AZT+3TC+Lpv/r,were evaluated between January 2010 and December 2012.Results The most frequent clinical side effect was fatigue (in 23 cases,88.5%),and gastroenterological symptoms were the second most common side effects in HCP with PEP.Liver dysfunction was found in 10 cases (38.5%),while drug rash was found in 18 cases (69.2%) after PEP.The prevalence of side effects in HCPs who experienced PEP was higher than that in HIV/AIDS patients P <0.05.One nurse (3.8%) experienced severe gastrointestinal symptoms,which led to withdrawal of PEP.No HIV infection was found during 6-month follow-up period.Conclusion HCPs who received occupational PEP with triple-drug regimen,AZT+3TC+Lpv/r,experienced different side effects,and the tolerability and safety of PEP regimen were good in this cohort.

    Benefit-risk of different anti-rabies post-exposure prophylaxis (PEP) strategies after scratches or bites from dogs with unknown rabies status is unknown in very low rabies risk settings. A cost-effectiveness analysis in metropolitan France using a decision-tree model and input data from 2001 to 2011. A cohort of 2807 patients, based on the mean annual number of patients exposed to category CII (minor scratches) or CIII (transdermal bite) dog attacks in metropolitan France between 2001 and 2011. Five PEP strategies: (A) no PEP for CII and CIII; (B) vaccine only for CIII; (C) vaccine for CII and CIII; (D) vaccine+ rabies immunoglobulin (RIG) only for CIII; and (E) vaccine for CII and vaccine+ RIG for CIII. The number of deaths related to rabies and to traffic accidents on the way to anti-rabies centers (ARC), effectiveness in terms of years of life gained by reducing rabies cases and avoiding traffic accidents, costs, and incremental cost-effectiveness ratios (ICER) associated with each strategy. Strategy E led to the fewest rabies cases (3.6 × 10(-8)) and the highest costs (€ 1,606,000) but also to 1.7 × 10(-3) lethal traffic accidents. Strategy A was associated with the most rabies cases (4.8 × 10(-6)), but the risk of traffic accidents and costs were null; therefore, strategy A was the most effective and the least costly. The sensitivity analysis showed that, when the probability that a given dog is rabid a given day (PA) was > 1.4 × 10(-6), strategy D was more effective than strategy A; strategy B became cost-effective (i.e. ICER vs strategy A 1 .4 × 10(-4). In the metropolitan France's very low rabies prevalence context, PEP with rabies vaccine, administered alone or with RIG, is associated with significant and unnecessary costs and unfavourable benefit-risk ratios regardless to exposure category.

    The risk for occupational exposure to HIV has been well characterized in the developed world, but limited information is available about this transmission risk in resource-constrained settings facing the largest burden of HIV infection. In addition, the feasibility and utilization of post-exposure prophylaxis (PEP) programs in these settings are unclear. Therefore, we examined the rate and characteristics of occupational exposure to HIV and the utilization of PEP among health care workers (HCW) in a large, urban government teaching hospital in Pune, India. Demographic and clinical data on occupational exposures and their management were prospectively collected from January 2003-December 2005. US Centers for Diseases Control guidelines were utilized to define risk exposures, for which PEP was recommended. Incidence rates of reported exposures and trends in PEP utilization were examined using logistic regression. Of 1955 HCW, 557 exposures were reported by 484 HCW with an incidence of 9.5 exposures per 100 person-years (PY). Housestaff, particularly interns, reported the greatest number of exposures with an annual incidence of 47.0 per 100 PY. Personal protective equipment (PPE) was used in only 55.1% of these exposures. The incidence of high-risk exposures was 6.8/100 PY (n = 339); 49.1% occurred during a procedure or disposing of equipment and 265 (80.0%) received a stat dose of PEP. After excluding cases in which the source tested HIV negative, 48.4% of high-risk cases began an extended PEP regimen, of whom only 49.5% completed it. There were no HIV or Hepatitis B seroconversions identified. Extended PEP was continued unnecessarily in 7 (35%) of 20 cases who were confirmed to be HIV-negative. Over time, there was a significant reduction in proportion of percutaneous exposures and high-risk exposures (p risk exposures (44% in 2003 to 100% in 2005, p = 0.002). Housestaff are a vulnerable population at high risk for bloodborne exposures in teaching hospital settings

    Herein we describe production of purified equine IgG obtained from horses immunized with plasmid DNA followed by boosting with Kunjin replicon virus-like particles both encoding a modified Ebola glycoprotein. Administration of the equine IgG over 5 days to cynomolgus macaques infected 24 hours previously with a lethal dose of Ebola virus suppressed viral loads by more than 5 logs and protected animals from mortality. Animals generated their own Ebola glycoprotein-specific IgG responses 9–15 days after infection, with circulating virus undetectable by day 15–17. Such equine IgG may find utility as a post-exposure prophylactic for Ebola infection and provides a low cost, scalable alternative to monoclonal antibodies, with extensive human safety data and WHO-standardized international manufacturing capability available in both high and low income countries.

    Health care workers (HCWs) are at high risk for acquiring hepatitis B virus infection because of needle stick injury (NSI) and occupational exposures to potentially infectious bodily fluids. Hepatitis B vaccination confers protection against the infection. Very little information is available in India about current vaccination status and postexposure prophylaxis (PEP) practices among HCWs. This study had 2 objectives. The first was to characterize current vaccination coverage among HCWs, and the second was to define PEP practices among HCWs after NSI and exposures to potentially infectious bodily fluids. A questionnaire-based, cross-sectional study was conducted in hospitals attached to Kasturba Medical College, Mangalore. We selected 297 individuals. A pretested, semistructured questionnaire was devised to collect information from study participants. After obtaining permission from the Institutional Ethics Committee, data were collected by interviewing HCWs in the hospitals. Analysis was done using SPSS. Nearly all (93.8%) of the HCWs surveyed had taken 1 dose of hepatitis B vaccine. However, only 57.1% completed the primary series of 3 doses and only 26.4% had taken 1 or more booster doses. Of the HCWs questioned, 24.8% had experienced NSIs, exposure to potentially infectious bodily fluids, or both. Local measures were the PEP practices most commonly used (85.5%) by the HCWs. The present study demonstrated that there is a need in Mangalore to improve the vaccination coverage and train HCWs in appropriate PEP practices. This will protect the workers from acquiring hepatitis B infection. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

    Objective To understand the current status of dog raising, post exposure treatment of rabies and awareness of rabies related knowledge among local and migrant people in rural area in Jiaxing, Zhejiang province. Methods A household interview was conducted in 2 villages selected from 5 townships by multi stage cluster sampling, the database was established by using EpiData 3. 0 and the data analysis was done by using SPSS 18. 0 software. Results Totally 346 households were surveyed, the dog raising rate was 45. 95% and average dog number per household was 1.4. Only 6. 19% of the dogs were immunized. The dog raising rate in local people was higher than that in migrant people. In the past two years, 4. 83% of the people surveyed were bitten by dogs, and 90. 8% of them went to hospitals timely for post exposure treatment and complete full series of vaccination, 3. 1% of those with wound at grade H received extra human rabies immunoglobulin. Most exposure occurred in July. Among the people surveyed, 94% knew that rabies vaccine should be received after being bitten by dogs or cats, 81. 8% knew the site of the rabies clinics and 77. 5% knew that rabies is a fatal disease. The awareness rate of rabies related knowledge was higher in local people than in migrant people. Conclusion The dog density was high and the dog immunization rate was low in Xiuzhou District. Some people bitten by dogs didn' t receive timely standard post exposure prophylaxis. It is necessary to strengthen the dog management, standardize the post exposure prophylaxis and conduct health education about rabies prevention and control in general population, especially in floating population.%目的 了解浙江省嘉兴市秀洲区农村地区本地与流动人口的养犬情况、犬伤暴露后就诊情况、狂犬病知识知晓情况.方法 利用整群分层抽样方法,2011年在全区5个镇(街道)抽取2个村,入户面对面调查,采用EpiData 3.0软件建立数据库,SPSS 18.0

    AV7909 vaccine being developed for post-exposure prophylaxis of anthrax disease may require fewer vaccinations and reduced amount of antigen to achieve an accelerated immune response over BioThrax(®) (Anthrax Vaccine Adsorbed). A phase 2, randomized, double-blind, BioThrax vacccine-controlled study was conducted to evaluate the safety and immunogenicity of three intramuscular vaccination schedules and two dose levels of AV7909 in 168 healthy adults. Subjects were randomized at a 4:3:2:4:2 ratio to 5 groups: (1) AV7909 on Days 0/14; (2) AV7909 on Days 0/28; (3) AV7909 on Days 0/14/28; (4) half dose AV7909 on Days 0/14/28; and (5) BioThrax vaccine on Days 0/14/28. Vaccinations in all groups were well tolerated. The incidences of adverse events (AEs) were 79% for AV7909 subjects and 65% for BioThrax subjects; 92% of AV7909 subjects and 87% of BioThrax subjects having AEs reported Grade 1-2 AEs. No serious AEs were assessed as potentially vaccine-related, and no AEs of potential autoimmune etiology were reported. There was no discernible pattern indicative of a safety concern across groups in the incidence or severity of reactogenicity events. Groups 2-4 achieved success for the primary endpoint, demonstrated by a lower 95% confidence limit of the percentage of subjects with protective toxin neutralizing antibody NF50 values (≥0.56) to be ≥40% at Day 63. Group 1 marginally missed the criterion (lower bound 95% confidence limit of 39.5%). Immune responses were above this threshold for Groups 1, 3 and 4 at Day 28 and all groups at Day 42. Further study of an AV7909 two-dose schedule given 2 weeks apart is warranted in light of the favorable tolerability profile and immunogenicity response relative to three doses of BioThrax vaccine, as well as preliminary data from nonclinical studies indicating similar immune responses correlate with higher survival for AV7909 than BioThrax vaccine.

    Full Text Available Abstract Background Post-exposure prophylaxis (PEP following sexual exposure to HIV has been recommended as a method of preventing HIV infection in the UK. Men who have sex with men (MSM are the group most affected by HIV in the UK and their sexual risk taking behaviour is reported to be increasing. One-to-one behavioural interventions, such as motivational interviewing (MI have been recommended to reduce HIV in high risk groups. The Information, Motivation and Behavioral skills (IMB model has been shown to provide a good basis for understanding and predicting HIV-relevant health behaviour and health behaviour change, however the IMB has yet to be applied to PEP after risky sexual exposure. The primary aim of this trial is to examine the impact of MI augmented with information provision and behavioural skills building (informed by the IMB Model, over and above usual care, on risky sexual behaviour in MSM prescribed PEP after potential sexual exposure. A secondary aim of this research is to examine the impact of the intervention on adherence to PEP. This study will also provide estimates of the cost-effectiveness of the intervention. Methods A manualised parallel group randomised controlled trial with economic evaluation will be conducted. The primary outcome is the proportion of risky sexual practices. Secondary outcomes include: i Levels of adherence to PEP treatment; ii Number of subsequent courses of PEP; iii Levels of motivation to avoid risky sexual behaviours; iv Levels of HIV risk-reduction information/knowledge; v Levels of risk reduction behavioural skills; vi Diagnosis of anal gonorrhoea, Chlamydia and/or HIV. 250 participants will be asked to self-complete a questionnaire at four time points during the study (at 0,3,6,12 months. The intervention will consist of a two-session, fixed duration, telephone administered augmented MI intervention based on the IMB model.

    Full Text Available Post-exposure vaccination with vaccinia virus (VACV has been suggested to be effective in minimizing death if administered within four days of smallpox exposure. While there is anecdotal evidence for efficacy of post-exposure vaccination this has not been definitively studied in humans. In this study, we analyzed post-exposure prophylaxis using several attenuated recombinant VACV in a mouse model. A recombinant VACV expressing murine interferon gamma (IFN-γ was most effective for post-exposure protection of mice infected with VACV and ectromelia virus (ECTV. Untreated animals infected with VACV exhibited severe weight loss and morbidity leading to 100% mortality by 8 to 10 days post-infection. Animals treated one day post-infection had milder symptoms, decreased weight loss and morbidity, and 100% survival. Treatment on days 2 or 3 post-infection resulted in 40% and 20% survival, respectively. Similar results were seen in ECTV-infected mice. Despite the differences in survival rates in the VACV model, the viral load was similar in both treated and untreated mice while treated mice displayed a high level of IFN-γ in the serum. These results suggest that protection provided by IFN-γ expressed by VACV may be mediated by its immunoregulatory activities rather than its antiviral effects. These results highlight the importance of IFN-γ as a modulator of the immune response for post-exposure prophylaxis and could be used potentially as another post-exposure prophylaxis tool to prevent morbidity following infection with smallpox and other orthopoxviruses.

    Full Text Available Objetivando analisar as indicações de profilaxia antirrábica humana no Município de Jaboticabal-SP, foi realizado um estudo retrospectivo descritivo no período de 2000 a 2006, com levantamento de dados registrados nas fichas de investigação de atendimento e cálculo do custo com as vacinas destinadas à profilaxia pós-exposição. Constatou-se que 2.493 pessoas agredidas por animais foram submetidas à profilaxia com uso de vacina, num total de 7.108 doses e um custo de R$ 179.105,14. Da totalidade de casos notificados, 2.184 (71,5 % foram causados por cães e gatos clinicamente sadios no momento da agressão e que assim se mantiveram durante o período de observação, a qual foi feita pela própria vítima ou pelo dono do animal. Considerando este fato e também a situação epidemiológica da raiva no Município, pode-se inferir que essas vítimas poderiam ter sido dispensadas da profilaxia; entretanto, apenas 464 o foram, ou seja, 1.720 pessoas podem ter recebido vacina sem necessidade, ou seja 4.590 doses a um custo de R$ 114.420,81. Em comparação com os números de outros municípios do Estado de São Paulo e com a média nacional, constata-se que o número de profilaxias pós-exposição contra raiva é muito alto em Jaboticabal, evidenciando que na conduta não se considerou o estado do agressor e a condição do Município de área controlada para raiva. Recomenda-se conscientização e capacitação permanentes das equipes de saúde pública quanto à epidemiologia da doença e à necessidade de observação adequada do animal agressor. É essencial a integração dos serviços médicos e veterinários no atendimento às vitimas, visando uma melhor avaliação do caso para que a decisão de se instituir ou não a profilaxia pós-exposição seja feita com critério e segurança.The present study aimed to evaluate rabies post-exposure prophylaxis (PEP in humans in the municipality of Jaboticabal, São Paulo from 2000 through

    The efficacy of hepatitis B immunoglobulin (HBIG) in preventing infection by hepatitis B virus (HBV) after exposure to blood or blood-containing secretions that carried hepatitis B surface antigen (HBsAg), was studied in an uncontrolled trial in Norway from 1976-1983. Of the 177 HBIG recipients, followed up for 5-24 months, 166 were exposed by needle-stick, splash on mucous membranes or open wounds, sexual contact or medical investigation. With few exceptions, this group was given a single injection of 1250 IU of antibody to HBsAg (anti-HBs) within 7 days after exposure. One person developed clinical hepatitis B (HB) of short duration and two others developed anti-HBs. Six infants with perinatal exposure were injected with three or four doses of about 1250 IU anti-HBs at intervals of 2-3 months. The first dose was given immediately after birth. One child developed clinical HB at the age of 14 months and recovered. Of five patients exposed by blood transfusion, four developed clinical HB; the fifth apparently developed passive-active immunity. One of the four probably became an HBsAg carrier. These patients, except the one without clearance of HBsAg, received one to seven doses of HBIG within 2 days after exposure. Administration of HBIG after needle-stick and similar types of exposure, as well as administration to infants at risk of contracting HB, seems to be of great value.

    Full Text Available Ebola viruses are highly lethal human pathogens that have received considerable attention in recent years due to an increasing re-emergence in Central Africa and a potential for use as a biological weapon. There is no vaccine or treatment licensed for human use. In the past, however, important advances have been made in developing preventive vaccines that are protective in animal models. In this regard, we showed that a single injection of a live-attenuated recombinant vesicular stomatitis virus vector expressing the Ebola virus glycoprotein completely protected rodents and nonhuman primates from lethal Ebola challenge. In contrast, progress in developing therapeutic interventions against Ebola virus infections has been much slower and there is clearly an urgent need to develop effective post-exposure strategies to respond to future outbreaks and acts of bioterrorism, as well as to treat laboratory exposures. Here we tested the efficacy of the vesicular stomatitis virus-based Ebola vaccine vector in post-exposure treatment in three relevant animal models. In the guinea pig and mouse models it was possible to protect 50% and 100% of the animals, respectively, following treatment as late as 24 h after lethal challenge. More important, four out of eight rhesus macaques were protected if treated 20 to 30 min following an otherwise uniformly lethal infection. Currently, this approach provides the most effective post-exposure treatment strategy for Ebola infections and is particularly suited for use in accidentally exposed individuals and in the control of secondary transmission during naturally occurring outbreaks or deliberate release.

The government has made efforts to control animal rabies in many aspects, but whether prophylactic strategy for human hydrophobia is performed adequately is in question. The rate of proper post-exposure prophylaxis for animal bite case in 'high-risk region' of rabies is very low with 20% between 2011 and 2013. The National Animal Bite Patient Surveillance targeting 'high-risk region' is missing out animal bite cases who visit directly to hospitals in 'suspect-risk region' of rabies. Little data seems to exist for pre-exposure prophylaxis of domestic hydrophobia. Danger of reoccurrence of human hydrophobia always remain in South Korea. The medical personnel needs to have greater interest on the matter and the government strengthen the management system.

Objective: The effectiveness of NI during treatment and post exposure prophylaxis (PEP of an influenza infection are analyzed from a medical and an economical perspective. The effectiveness of NI in seasonal prophylaxis is not investigated in this report. Safety aspects of the drugs are also discussed. Methods: The relevant literature was identified by a systematic, structured bibliographic data base review. In addition, a manual search of relevant journals was conducted. The structured electronic data base analysis was supported by DIMDI and comprised the bibliographic data bases MEDLINE, HealthStar, Current Contents/Clinical Medicine, EMBASE, DA-RA, Cochrane Library, CancerLit, as well as Dissertation Abstracts for the period between 1999 and September 2004. Pre-defined key words were linked by AND/OR operators. A manual search of the Cochrane register was conducted for the time period before September 1999. Relevant medical journals were also hand-searched from January to November 2004. Quantitative reviews, randomized, double-blind clinical trials (RCT, and cost-benefit-analyses were considered as relevant if they fulfilled predefined inclusion criteria. Results: As compared to placebo, NI shortened the median duration of symptoms by approximately one day in meta-analyses, when the drug was taken within 48 hours after the onset of symptoms. The symptom reduction for other subgroups (such as patients who are at-risk for complicated influenza courses was even greater. For children under twelve, however, this was not the case. However, the incidence of severe influenza courses which led to hospitalization or death was low in the controlled studies. Pooled analyses nevertheless showed a tendency of a possible benefit of NI with respect to the hospitalization rate. Regarding PEP in homes with one infected household member, the reviewed studies showed a prophylactic effect of inhaled Zanamivir and Oseltamivir if a person started

    Sensitization to epoxy resins often results from occupational exposure in various fields of construction and industry. Non-occupational sensitization sources and environments have remained overlooked. To analyse non-occupational and occupational contact sensitization to epoxy resin of bisphenol A among general dermatology patients. Special attention was paid to patients sensitized from non-occupational sources. During a 10-year period, 6042 general dermatology patients were patch tested with epoxy resin (bisphenol A) in the Dermatology Clinic of Turku University Hospital. The clinical data and the sources of occupational and non-occupational exposure to epoxy resin were analysed in sensitized patients. Epoxy resin sensitization was found in 59 patients. Non-occupational sensitization was found in 21 (35%) patients, whereas the number of occupational cases was 38 (65%). The most common sources of non-occupational epoxy resin sensitization were materials used in domestic renovation and construction projects and in boat repair. Non-occupational sensitization sources account for approximately one-third of epoxy resin sensitization cases, and therefore represent an important risk among hobbies and leisure activities. © 2011 John Wiley & Sons A/S.

  17. Effects on health of non-occupational exposure to airborne mineral fibres.

    The most prominent potential marker of disease-related non-occupational exposure to mineral fibres is mesothelioma. Although many cases of mesothelioma have resulted from occupational exposure to asbestos, some have been associated with para-occupational domestic and/or neighbourhood exposure and have been reported in case series, case-control studies and a cohort study among non-occupationally exposed subjects. However, little information is available on mesothelioma as a direct consequence of general environmental asbestos exposure. Such cases of mesothelioma related to non-occupational exposure to asbestos as have occurred to date are likely to have resulted from past exposures much higher than those prevailing at the present time (in the developed countries); numbers will therefore probably decrease in the future. Very high rates of mesothelioma have been reported as a result of exposure to erionite. No studies are available on the effects of non-occupational exposure to man-made mineral fibres but, among occupationally exposed workers, a risk of mesothelioma is not apparent. There are suggestions of raised lung cancer rates among household contacts of asbestos workers and among individuals exposed to erionite. Non-malignant parenchymal and pleural abnormalities have been observed in subjects exposed non-occupationally to asbestos and erionite, but these are not necessarily associated with malignant lesions. Quantitative risk estimates of adverse effects on health have not been derived from these studies, essentially because of the absence of fibre exposure measurements.

    Tobacco use is the second cause of death and first cause of preventable mortality worldwide. Smoking in the workplace is particularly concerning. Smoking-free workplaces decrease the risk of exposure of non-smoking personnel to cigarette smoke. Recent studies have mostly focused on the effect of daily or non-occupational stressors (in comparison with occupational stress) on prevalence of smoking. Occupational stress is often evaluated in workplaces for smoking cessation or control programs, but the role of non-occupational stressors is often disregarded in this respect. This cross-sectional study was conducted in an automobile manufacturing company. The response of automotive industry workers to parts of the validated, reliable, Farsi version of Musculoskeletal Intervention Center (MUSIC)-Norrtalje questionnaire was evaluated. A total of 3,536 factory workers participated in this study. Data were analyzed using SPSS and P<0.05 was considered statistically significant. The correlation of smoking with demographic factors, occupational stressors and life events was evaluated. The results of logistic regression analysis showed that even after adjusting for the confounding factors, cigarette smoking was significantly correlated with age, sex, level of education, job control and life events (P<0.05). The results showed that of occupational and non-occupational stressors, only job control was correlated with cigarette smoking. Non-occupational stressors had greater effect on cigarette smoking. Consideration of both non-occupational and occupational stressors can enhance the success of smoking control programs. On the other hand, a combination of smoking control and stress (occupational and non-occupational) control programs can be more effective than smoking cessation interventions alone.

    Burkholderia pseudomallei is the causative agent of the disease melioidosis, which is prevalent in tropical countries and is intractable to a number of antibiotics. In this study, the antibiotic co-trimoxazole (trimethoprim/sulfamethoxazole) was assessed for the post-exposure prophylaxis of experimental infection in mice with B. pseudomallei and its close phylogenetic relative Burkholderia mallei, the causative agent of glanders. Co-trimoxazole was effective against an inhalational infection with B. pseudomallei or B. mallei. However, oral co-trimoxazole delivered twice daily did not eradicate infection when administered from 6h post exposure for 14 days or 21 days, since infected and antibiotic-treated mice succumbed to infection following relapse or immunosuppression. These data highlight the utility of co-trimoxazole for prophylaxis both of B. pseudomallei and B. mallei and the need for new approaches for the treatment of persistent bacterial infection.

    Antimicrobial prophylaxis is commonly used by clinicians for the prevention of numerous infectious diseases, including herpes simplex infection, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, infective endocarditis, pertussis, and acute necrotizing pancreatitis, as well as infections associated with open fractures, recent prosthetic joint placement, and bite wounds. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infections. Optimal antimicrobial agents for prophylaxis should be bactericidal, nontoxic, inexpensive, and active against the typical pathogens that can cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be administered within 30 to 60 minutes before the surgical incision. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost.

    Antimicrobial prophylaxis in surgery refers to a very brief course of an antimicrobial agent initiated just before the start of the procedure. The efficacy of antimicrobials to prevent postoperative infection at the site of surgery (incisional superficial, incisional deep, or organ/space infection) has been demonstrated for many surgical procedures. Nevertheless, the majority of studies centering on the quality of preoperative prophylaxis have found that a high percentage of the antimicrobials used are inappropriate for this purpose. This work discusses the scientific basis for antimicrobial prophylaxis, provides general recommendations for its correct use and specific recommendations for various types of surgery. The guidelines for surgical antimicrobial prophylaxis are based on results from well-designed studies, whenever possible. These guidelines are focussed on reducing the incidence of infection at the surgical site while minimizing the contribution of preoperative administration of antimicrobials to the development of bacterial resistance.

  6. Mechanisms of immunity in post-exposure vaccination against Ebola virus infection.

    Directory of Open Access Journals (Sweden)

    Steven B Bradfute

    Full Text Available Ebolaviruses can cause severe hemorrhagic fever that is characterized by rapid viral replication, coagulopathy, inflammation, and high lethality rates. Although there is no clinically proven vaccine or treatment for Ebola virus infection, a virus-like particle (VLP vaccine is effective in mice, guinea pigs, and non-human primates when given pre-infection. In this work, we report that VLPs protect Ebola virus-infected mice when given 24 hours post-infection. Analysis of cytokine expression in serum revealed a decrease in pro-inflammatory cytokine and chemokine levels in mice given VLPs post-exposure compared to infected, untreated mice. Using knockout mice, we show that VLP-mediated post-exposure protection requires perforin, B cells, macrophages, conventional dendritic cells (cDCs, and either CD4+ or CD8+ T cells. Protection was Ebola virus-specific, as marburgvirus VLPs did not protect Ebola virus-infected mice. Increased antibody production in VLP-treated mice correlated with protection, and macrophages were required for this increased production. However, NK cells, IFN-gamma, and TNF-alpha were not required for post-exposure-mediated protection. These data suggest that a non-replicating Ebola virus vaccine can provide post-exposure protection and that the mechanisms of immune protection in this setting require both increased antibody production and generation of cytotoxic T cells.

    Full Text Available Background: Post-exposure prophylaxis plays an important role in prevention of bloodborne diseases after occupational exposures. Objective: To evaluate the knowledge, attitude and practice of dentists towards post-exposure prophylaxis. Methods: In a cross-sectional study, 140 dentists in Shiraz were selected through a systematic randomized sampling. They filled out a self-made questionnaire including 30 knowledge, 4 attitude and 10 practice questions. Mean of knowledge and percentage of various items of attitude and practice were reported. Results: The mean±SD knowledge score of dentists was 18.5±6.2. Knowledge had a significant relationship with the level of education (p<0.001, attending infection control seminars (p<0.001, and working in public clinics (p<0.001. A total of 63 (43% dentists believed that immediate washing of the exposed area has no effect on the prevention of hepatitis and AIDS. Of the studied dentists, 13%, 11%, and 34% believed that prophylaxis after exposure to patients' blood had no effect on prevention of human immunodeficiency virus (HIV, hepatitis B virus, and hepatitis C virus infections, respectively. Only 170 (53% exposed dentists immediately washed the exposed area and only 43 (13.4% of them evaluated the source patient for risk factors of hepatitis and AIDS. Conclusion: Knowledge, attitude and practice of dentists working in Shiraz towards postexposure prophylaxis are not desirable. Interventions to raise their awareness are therefore warranted.

    Full Text Available Aim: Antibiotic prophylaxis aims to prevent infection of surgical sites before contamination or infection occurs. Prolonged antibiotic prophylaxis does not enhance the prevention of surgical infection and is associated with higher rates of antibiotic-resistant microorganisms. This review of the literature concerning antibiotic prophylaxis, with an emphasis on otolaryngologic surgery, aims to develop a guide for the use of antibiotic prophylaxis in otolaryngologic surgery in order to reduce the numbers of complications stemming from the indiscriminate use of antibiotics.

    The ability of galantamine hydrobromide (GAL HBr) treatment to antagonize O-ethyl-S-(2-diisopropylaminoethyl) methylphosphonothiolate (VX)-induced lethality, impairment of muscle tension, and electroencephalographic (EEG) changes was assessed in guinea pigs. Guinea pigs were challenged with 16.8 microg/kg VX (2LD50). One min after challenge, animals were administered 0.5 mg/kg atropine sulfate (ATR) and 25 mg/kg pyridine-2-aldoxime methochloride (2-PAM). In addition, guinea pigs were given 0, 1, 2, 4, 8 or 10 mg/kg GAL as a post-exposure treatment immediately prior to ATR and 2-PAM. Animals were either monitored for 24-h survival, scheduled for electroencephalography (EEG) recording, or euthanized 60 min later for measurement of indirectly-elicited muscle tension in the hemidiaphragm. Post-exposure GAL therapy produced a dose-dependent increase in survival from lethal VX challenge. Optimal clinical benefits were observed in the presence of 10 mg/kg GAL, which led to 100% survival of VX-challenged guinea pigs. Based on muscle physiology studies, GAL post-exposure treatment protected the guinea pig diaphragm, the major effector muscle of respiration, from fatigue, tetanic fade, and muscular paralysis. Protection against the paralyzing effects of VX was dose-dependent. In EEG studies, GAL did not alter seizure onset for all doses tested. At the highest dose tested (10 mg/kg), GAL decreased seizure duration when administered as a post-exposure treatment 1 min after VX. GAL also reduced the high correlation associated between seizure activity and lethality after 2LD50 VX challenge. GAL may have additional benefits both centrally and peripherally that are unrelated to its established mechanism as a reversible acetylcholinesterase inhibitor (AChEI).

    Post-exposure bioassays are used in environmental assessment as a cost-effective tool, but the effects of organism's recovery after exposure to pollutant has not yet been addressed in detail. The recoveries of post-exposure feeding rates after being exposed to two sublethal concentrations of cadmium during two different exposure periods (48 h and 96 h) were evaluated under laboratory conditions using the estuarine isopod Cyathura carinata. Results showed that feeding depression was a stable endpoint up to 24 h after cadmium exposure, which is useful for ecotoxicological bioassays. - Highlights: • We studied recovery of post-exposure feeding rates 48–96 h after cadmium exposure. • The assay is based on the isopod Cyathura carinata. • Post-exposure feeding inhibition is a stable sublethal endpoint.

    2004-06-01

    Antifungal prophylaxis represents a significant advance in the management of patients at risk from fungal infections in a variety of settings. Identification of patients at the highest risk and the utilisation of safe and effective drugs maximises the benefits of prophylaxis. Situations in which antifungal prophylaxis has been shown to be useful are bone marrow transplantation, liver and lung transplantation, surgical and neonatal intensive care units, secondary prophylaxis of fungal infections associated with HIV and neutropenia associated haematological malignancies and their treatment. New antifungal agents, such as the echinocandins and the new azoles, are available and have a potential role in antifungal prophylaxis. Future studies should evaluate which strategy is more useful; prophylaxis or pre-emptive therapy.

    The deprotection blur of Rohm and Haas XP 5435, XP 5271, and XP5496 extreme ultraviolet photoresists has been determined as their base weight percent is varied. They have also determined the deprotection blur of TOK EUVR P1123 photoresist as the post-exposure bake temperature is varied from 80 C to 120 C. In Rohm and Haas XP 5435 and XP5271 resists 7x and 3x (respective) increases in base weight percent reduce the size of successfully patterned 1:1 line-space features by 16 nm and 8 nm with corresponding reductions in deprotection blur of 7 nm and 4 nm. In XP 5496 a 7x increase in base weight percent reduces the size of successfully patterned 1:1 line-space features from 48 nm to 38 nm without changing deprotection blur. In TOK EUVR P1123 resist, a reduction in post-exposure bake temperature from 100 C to 80 C reduces deprotection blur from 21 nm to 10 nm and reduces patterned LER from 4.8 nm to 4.1 nm.

    Sulfur mustard (SM), a chemical weapon used widely during World War I and against Iranians during the Iran-Iraq War of the 1980s, causes massive inflammatory tissue damage in the immediate post-exposure period, resulting in debilitating chronic disease in years to decades following contact with the agent. These syndromes most often are pathologies of the lungs, eyes, and skin, the primary target organs of SM. Typically, they are characterized by severe and increasingly painful inflammation, often accompanied by fibrosis and constriction of the anatomic channels needed for normal life, such as the small airways of the lungs and, in the present report, the urethra. The present case study is a 43-year-old man with a history of heavy SM exposure to the groin in 1984. Within 1 year after exposure, the patient was found to have developed meatal stricture, occlusion of the external urethral meatus, and difficulty in urination. Two years post-exposure, he underwent ventral meatotomy and meatoplasty. This case presents a unique example of the latent effects of SM exposure to the groin, and will be of value in the prevention of similar injury and complications to persons at risk of SM exposure in the future.

    The current study evaluated the technical feasibility of applying TiO2 photocatalysis to the removal of low-ppb concentrations of volatile organic compounds (VOCs) commonly associated with non-occupational indoor air quality issues. A series of experiments was conducted to evaluate five parameters (relative humidity (RH), hydraulic diameter (HD), feeding type (FT) for VOCs, photocatalytic oxidation (PCO) reactor material (RM), and inlet port size (IPS) of PCO reactor) in relation to the PCO destruction efficiencies of the selected target VOCs. None of the target VOCs exhibited any significant dependence on the RH, which is inconsistent with a previous study where, under conditions of low humidity and a ppm toluene inlet level, a drop in the PCO efficiency was reported with a decreasing humidity. However, the other four parameters (HD, RM, FT, and IPS) were found to be important for better VOC removal efficiencies as regards the application of TiO2 photocatalytic technology for cleansing non-occupational indoor air. The PCO destruction of VOCs at concentrations associated with non-occupational indoor air quality issues was up to nearly 100%, and the CO generated during PCO was a negligible addition to indoor CO levels. Accordingly, a PCO reactor would appear to be an important tool in the effort to improve non-occupational indoor air quality.

    Phthalates have been used worldwide and are ubiquitous in environmental media and human bodies. Based on existing data on phthalate concentrations, distributions of phthalates in the environment and their exposure assessment to non-occupational populations in China can be evaluated. Fifty-three studies, published from January 2000 to October 2010, were reviewed and their data were analyzed in this study. Geographic information system (GIS) was used in mapping the published data of phthalate concentrations and their distributions in environmental media, while scatter diagrams were applied to show the time trends for phthalate concentrations in various environmental media. Results showed that there was a time-dependent increase in ∑phthalates (total phthalates) and DEHP concentrations in air during the past 10 years; phthalate concentrations varied in different areas, among which Guangdong and northeast China were the most polluted. Using Clark's equations, daily intake of ∑phthalates and DEHP in the Pearl River Delta and the Yangtze River Delta was estimated from consumption of contaminated food, water and air. Results showed that daily intake of ∑phthalates and DEHP was 128.63 and 61.29 μg/kg BW/d for adults in the Pearl River Delta, which is significantly higher than those residing in the Yangtze River Delta (33.87 and 24.68 μg/kg BW/d).

  19. Critical dimension sensitivity to post-exposure bake temperaturevariation in EUV photoresists

    Chemically amplified resists depend upon the post-exposure bake (PEB) process to drive the deprotection reactions (in positive resists) that lead to proper resist development. For this reason they often exhibit critical dimension (CD) sensitivity to PEB temperature variation. In this work the effects of variation in different aspects of the PEB step on post-develop CD are studied for two extreme ultraviolet (EUV) photoresists. The spatial and temporal temperature uniformity of the PEB plate is measured using a wireless sensor wafer. Programmed variations in the bake plate temperature set point are then used to measure the CD sensitivity to steady state temperature variation. In addition, the initial temperature ramp time is modified using a thin sheet of polyimide film between the wafer and the bake plate. This allows for measurement of the CD sensitivity to transient temperature variation. Finally, the bake time is adjusted to measure the CD sensitivity to this parameter.

    To achieve high volume manufacturing, EUV photoresists need to push back the "RLS trade-off" by simultaneously improving Resolution, Line-Width Roughness and Sensitivity (exposure dose). Acid diffusion in chemically amplified resist is known to impact these performances. This work studies the diffusion of acid in chemically amplified resist by varying the post exposure bake duration while monitoring the evolution of CD and LWR for 6 chemically amplified EUV photoresists (CAR). We observed a first regime where both CD and LWR quickly decrease during the first 30s of post exposure bake (PEB). This can be related to the deprotection reaction taking place in the exposed part of the resist. After 60s the decrease in CD and LWR slows down significantly, likely related to a regime of acid diffusion from exposed to unexposed region, and acid-quencher neutralization at the interface of these two regions. We tested two resists with different protecting group and the one having lower activation energy shows a faster CD change in the second regime, resulting in a worsening of LWR for longer PEB time. On the contrary, a resist with a high quencher loading shows reduced net diffusion of acid towards the unexposed region and controls the resist edge profile. In other words longer PEB does not degrade LWR, but as it reduces the line CD, sensitivity is impacted. With an appropriate ratio selection of quencher to PAG, an EUV dose reduction of up to 12% can be achieved with a change from a standard 60 second to a 240 second PEB time, while keeping LWR and resolution constant and therefore pushing the RLS performances. Finally, we confirmed that the observations on positive tone development (PTD) resist could be applied to negative tone development (NTD) resist: with a high quencher NTD resist we observed a dose reduction of 8% for longer PEB time, keeping LWR and resolution constant.

    Full Text Available Introduction: The potential oncogenic effect of some heavy metals in people occupationally and non-occupationally exposed to such heavy metals is already well demonstrated. This study seeks to clarify the potential role of these heavy metals in the living environment, in this case in non-occupational multifactorial aetiology of malignancies in the inhabitants of areas with increased prevalent environmental levels of heavy metals. Methods: Using a multidisciplinary approach throughout a complex epidemiological study, we investigated the potential oncogenic role of non-occupational environmental exposure to some heavy metals [chrome (Cr, nickel (Ni, copper (Cu, zinc (Zn, cadmium (Cd, lead (Pb and arsenic (As—in soil, drinking water, and food, as significant components of the environment] in populations living in areas with different environmental levels (high vs. low of the above-mentioned heavy metals. The exposures were evaluated by identifying the exposed populations, the critical elements of the ecosystems, and as according to the means of identifying the types of exposure. The results were interpreted both epidemiologically (causal inference, statistical significance, mathematical modelling and by using a GIS approach, which enabled indirect surveillance of oncogenic risks in each population. Results: The exposure to the investigated heavy metals provides significant risk factors of cancer in exposed populations, in both urban and rural areas [χ² test (p < 0.05]. The GIS approach enables indirect surveillance of oncogenic risk in populations. Conclusions: The role of non-occupational environmental exposure to some heavy metals in daily life is among the more significant oncogenic risk factors in exposed populations. The statistically significant associations between environmental exposure to such heavy metals and frequency of neoplasia in exposed populations become obvious when demonstrated on maps using the GIS system.

    Full Text Available Background: During the one-year period from May 2008 to May 2009, a nationwide shortage developed which rabies vaccine was not being produced by the manufacturers. In order to manage existing supply, a protocol was established wherein an authorization was required from the regional poison center before vaccine could be administered to a patient. Methods: The Georgia Poison Center internal database was accessed for information pertaining to rabies exposure calls for the time of the restriction, as well as the years before and after. Results were examined for the total number of human rabies exposure calls received by the poison center, as well as the number of cases in which PEP was recommended.  Results: During the restriction period, the number of rabies-related calls increased, while the percentage of cases in which PEP was recommended, remained consistent. The year following the restriction, the number of rabies related calls remained elevated. Conclusion: Our Regional Poison Center was able to make a positive impact by reducing unnecessary use of PEP in a time of shortage and thereby ensuring that all patients who needed the vaccine were able to receive it. This further shows the potential capacity of the poison information centers to optimize healthcare services.

    Compared to traditional toxicological studies, which depict the dose-effect of contaminants themselves on organisms at the given time, the exposure and post-exposure impacts of antibiotic ceftazidime and its photoproducts are carried out to systematically evaluate the environmental risk fate of ceftazidime in aquatic environments. For the exposure process, the promotion effect of ceftazidime on the feeding behavior of the rotifers decreased when the target compound was irradiated by sunlight, and the promotion effect was converted into inhibition effect, which indicated that the highest toxicity of ceftazidime on the feeding behavior of the rotifers was found after UV-B irradiation. The overcompensation occurred in the post-exposure, indicating a short - term effect of the corresponding photoproducts on the rotifer. In order to better understand the mechanism of this change, the photodegradation pathways of the target compound was analyzed and compared. The degradation degree under the UV-B irradiation had intensified greatly than that under the nature light irradiation. The reactive oxygen species (ROS) of the rotifer in exposure and post-exposure was also detected. Ceftazidime and photoproducts induced generation of ROS, indicating that oxidative damage occurred, and the decreasing of ROS levels could be viewed as the recovery of the rotifers in the post-exposure.

    Metabolic adjustments were studied in channel catfish Ictalurus punctatus exposed to 1.5 mg L-1 of phe nol (10% LC50) for four days and recovered for seven days. Lower triacylglycerol (TGA) stores and increased muscle fat free acids (FFA) suggest fat catabolism in muscle. Remarkable liver FFA decrease (-31%) suggests liver fat catabolism as well. Increased muscular ammonia levels and ASAT (aspartate aminotransferase) and decreased plasma aminoacids suggest higher muscular amino acid uptake. Constant levels of glucose and increased liver glycogen stores, associated with lower amino acids in plasma, indicate gluconeogenesis from amino acids. This is supported by higher hepatic ALAT and ASAT. Higher hepatic LDH followed by lower plasma lactate may indicate that plasma lactate was also used as gluconeogenic substrate. Biochemical alterations were exacerbated during the post-exposure recovery period. Reduction in muscle and plasma protein content indicate proteolysis. A higher rate of liver fat catabolism was resulted from a remarkable decrease in hepatic TGA (-58%). Catabolic preference for lipids was observed in order to supply such elevated energy demand. This study is the first insight about the metabolic profile of I. punctatus to cope with phenol plus its ability to recover, bringing attention to the biological consequences of environmental contamination.

    2004-01-01

    Bacterial endocarditis (BE) is a disease resulting from the association of morphological alterations of the heart and bacteraemia originating from different sources that at times can be indiscernible (infectious endocarditis). It is classified on the basis of the morphological alteration involved, depending on the clinical manifestations and course of illness, which varies according to the causative microorganism and host conditions (for example, it is characteristic in I.V. drug users). The most common microorganisms involved are: Streptococcus viridans (55%), Staphylococcus aureus (30%), Enterococcus (6%) and HACEK bacteria (corresponding to the initials: Haemophilus, Actinobacillus, Cardiobacterium, Eikenella and Kingella), although on occasions it can also be caused by fungi. The oral microbiological flora plays a very important role in the aetiopathogenesis of BE, given that the condition may be of oral or dental origin. This paper will deal with the prevention of said bacteraemia. Prophylaxis will be undertaken using amoxicillin or clindamycin according to action protocols, with special emphasis placed on oral hygiene in patients with structural defects of the heart.

    2014-03-01

    Sub-millisecond laser post-exposure bake (PEB) is an alternative technology to address the excessive acid diffusion for chemically amplified photoresist systems. By rationally designing the resist, laser post-exposure bake is able to improve the resolution and reduce the line width roughness (LWR) compared to patterns exposed under the same conditions but using conventional hotplate PEB. It was found that only the resist with high deprotection activation energy and low diffusion activation energy showed improved performance using laser PEB. Accordingly, a PAG was designed to have low acid diffusivity by binding the counter ions to a molecular glass core while keeping photophysical properties and processing conditions similar to a conventional PAG. By reducing the diffusivity of the counter ions, the PAG was able to further reduce LWR by 60% using laser PEB.

    Full Text Available Carbon monoxide (CO poisoning can be fatal but is preventable. From October 2010 to February 2011, Anshan Prefecture reported 57 cases of non-occupational CO poisoning in District A, with two deaths. We conducted an investigation to identify risk factors and recommend preventive measures.We defined a possible case of non-occupational CO poisoning as onset of at least two of the following symptoms: fatigue, headache, dizziness, nausea, vomiting, cyanosis, loss of consciousness, coma, and shock from October 1, 2010, to February 28, 2011, in a resident of Anshan Prefecture with non-occupational exposure to CO poisoning. We defined a probable case as onset of at least one of the following symptoms: cyanosis, loss of consciousness, coma and shock, plus at least one of the following symptoms: fatigue, headache, dizziness, nausea, vomiting, among possible cases. A confirmed CO poisoning case was a possible case or probable case plus hemoglobin (Hb CO higher than 10%. We searched for cases by reviewing medical records and records of hyperbaric oxygen tank usage. In a case-control investigation, we compared home heating practices of 30 case-persons and 120 control-persons who were individually matched to each case by neighborhood.Overall, 56% (39/70 of case-patients' households burned coal for home-heating.

    Full Text Available Abstract Background Current epidemiological data highlight the potential detrimental associations between sedentary behaviours and health outcomes, yet little is known about temporal trends in adult sedentary time. This study used time use data to examine population trends in sedentary behaviours in non-occupational domains and more specifically during leisure time. Methods We conducted secondary analysis of population representative data from the Australian Time Use Surveys 1992, 1997 and 2006 involving respondents aged 20 years and over with completed time use diaries for two days. Weighted samples for each survey year were: n = 5851 (1992, n = 6419 (1997 and n = 5505 (2006. We recoded all primary activities by domain (sleep, occupational, transport, leisure, household, education and intensity (sedentary, light, moderate. Adjusted multiple linear regressions tested for differences in time spent in non-occupational sedentary behaviours in 1992 and 1997 with 2006 as the reference year. Results Total non-occupational sedentary time was slightly lower in 1997 than in 2006 (mean = 894 min/2d and 906 min/2d, respectively; B = −11.2; 95%CI: -21.5, -0.9. Compared with 2006, less time was spent in 1997 in sedentary transport (B-6.7; 95%CI: -10.4, -3.0 and sedentary education (B = −6.3; 95%CI: -10.5, -2.2 while household and leisure sedentary time remained stable. Time engaged in different types of leisure-time sedentary activities changed between 1997 and 2006: leisure-time computer use increased (B = −26.7; 95%CI: -29.5, -23.8, while other leisure-time sedentary behaviours (e.g., reading, listening to music, hobbies and crafts showed small concurrent reductions. In 1992, leisure screen time was lower than in 2006: TV-viewing (B = −24.2; 95%CI: -31.2, -17.2, computer use (B = −35.3; 95%CI: -37.7, -32.8. In 2006, 90 % of leisure time was spent sedentary, of which 53 % was screen time. Conclusions Non-occupational

    Full Text Available Invasive fungal infections (IFIs represent significant complications in patients with hematological malignancies. Chemoprevention of IFIs may be important in this setting, but most antifungal drugs have demonstrated poor efficacy, particularly in the prevention of invasive aspergillosis. Antifungal prophylaxis in hematological patients is currently regarded as the gold standard in situations with a high risk of infection, such as acute leukemia, myelodysplastic syndromes, and autologous or allogeneic hematopoietic stem cell transplantation. Over the years, various scientific societies have established a series of recommendations for antifungal prophylaxis based on prospective studies performed with different drugs. However, the prescription of each agent must be personalized, adapting its administration to the characteristics of individual patients and taking into account possible interactions with concomitant medication.

    Full Text Available The acute toxicity of organophosphates is usually attributed to their irreversible inhibitionof an enzyme acetylcholinesterase that hydrolyses the neurotransmitter acetylcholine. Theresultant increase in concentration of acetylcholine at the cholinergic synapses of the peripheraland central nervous system, and neuromuscular junction is manifested by over-stimulation ofthe cholinergic neurotransmission. Current antidotal regimens for organophosphate poisoningconsisting of a post-exposure therapy with anticholinergics such as atropine, acetylcholinesterasereactivators (oximes, benzodiazepines have some limitations. Therefore, effective prophylaxisbefore intoxication is of a special interest. Four fundamental prophylactic methods are: (iprotection of acetylcholinesterase against irreversible inhibition by organophosphates usingdifferent reversible inhibitors, (ii protection against neurotoxic effect of organophosphates usingbenzodiazepines, memantine, NMDA receptor blockers, (iii administration of cholinesterasepreparations of different sources (sometimes commercially available at present acting asbioscavengers, and (iv gene therapy being a new treatment modality under intensive researchusing enzymes hydrolysing/splitting organophosphates with the aim to eliminate toxic agentbefore it is transported to the target organs.

    The aim of this study is to review and summarize the relevant literature regarding pharmacologic and non-pharmacologic methods of prophylaxis against gastrointestinal (GI) stress ulceration, and upper gastrointestinal bleeding in critically ill patients. Stress ulcers are a known complication of a variety of critical illnesses. The literature regarding epidemiology and management of stress ulcers and complications thereof, is vast and mostly encompasses patients in medical and surgical intensive care units. This article aims to extrapolate meaningful data for use with a population of critically ill neurologic and neurosurgical patients in the neurological intensive care unit setting. Studies were identified from the Cochrane Central Register of controlled trials and NLM PubMed for English articles dealing with an adult population. We also scanned bibliographies of relevant studies. The results show that H(2)A, sucralfate, and PPI all reduce the incidence of UGIB in neurocritically ill patients, but H(2)A blockers may cause encephalopathy and interact with anticonvulsant drugs, and have been associated with higher rates of nosocomial pneumonias, but causation remains unproven and controversial. For these reasons, we advocate against routine use of H(2)A for GI prophylaxis in neurocritical patients. There is a paucity of high-level evidence studies that apply to the neurocritical care population. From this study, it is concluded that stress ulcer prophylaxis among critically ill neurologic and neurosurgical patients is important in preventing ulcer-related GI hemorrhage that contributes to both morbidity and mortality. Further, prospective trials are needed to elucidate which methods of prophylaxis are most appropriate and efficacious for specific illnesses in this population.

    Three different regimens of antibiotic treatment have been employed in order to evaluate their efficacy as a profilaxis for abdominal hysterectomy. Two short term administrations (Cephtriaxone and Cephamandole plus Tobramycine) and a conventional full dose treatment (Cephazoline) have been compared over a group of homogeneous patients. No significant differences, except a reduction in postoperative time spent in hospital, have been found among the groups. A reduction in urinary tract infection has also been reported with a single-dose antibiotic prophylaxis.

    Consistent with evidence of a strong correlation between interferon gamma (IFNγ) production and rabies virus (RABV) clearance from the CNS, we recently demonstrated that engineering a pathogenic RABV to express IFNγ highly attenuates the virus. Reasoning that IFNγ expression by RABV vaccines would enhance their safety and efficacy, we reverse-engineered two proven vaccine vectors, GAS and GASGAS, to express murine IFNγ. Mortality and morbidity were monitored during suckling mice infection, immunize/challenge experiments and mixed intracranial infections. We demonstrate that GASγ and GASγGAS are significantly attenuated in suckling mice compared to the GASGAS vaccine. GASγ better protects mice from lethal DRV4 RABV infection in both pre- and post-exposure experiments compared to GASGAS. Finally, GASγGAS reduces post-infection neurological sequelae, compared to control, during mixed intracranial infection with DRV4. These data show IFNγ expression by a vaccine vector can enhance its safety while increasing its efficacy as pre- and post-exposure treatment. - Highlights: • IFNγ expression improves attenuated rabies virus safety and immunogenicity. • IFNγ expression is safer and more immunogenic than doubling glycoprotein expression. • Co-infection with IFNγ-expressing RABV prevents wild-type rabies virus lethality. • Vaccine safety and efficacy is additive for IFNγ and double glycoprotein expression.

    Rabies is an essentially 100% fatal, zoonotic disease, caused by Lyssaviruses. Currently, the disease is vaccine-preventable with pre- and post-exposure prophylaxis (PrEP and PEP). Still, rabies virus is estimated to cause up to 60,000 human deaths annually, of which the vast majority occurs in rural Asia and Africa, due to the inaccessibility of prophylaxis and non-existence of treatment. Despite these unmet clinical needs, rabies control mainly focuses on the sylvatic reservoir and drug innovation receives relatively little attention compared to other neglected tropical diseases (NTDs). As such, the lag of innovation in human rabies prophylaxis and treatment cannot be explained by limited return on investment alone. Strategies countering rabies-specific innovation barriers are important for the acceleration of innovation in human rabies prophylaxis and treatment. Barriers throughout society, science, business development and market domains were identified through literature review and 23 semi-structured interviews with key opinion leaders worldwide. A subsequent root cause analysis revealed causal relations between innovation barriers and a limited set of root causes. Finally, prioritization by experts indicated their relative importance. Root causes, which are fundamental to barriers, were aggregated into four types: market and commercial, stakeholder collaboration, public health and awareness, and disease trajectory. These were found in all domains of the innovation process and thus are relevant for all stakeholders. This study identifies barriers that were not previously described in this specific context, for example the competition for funding between medical and veterinary approaches. The results stress the existence of barriers beyond the limited return on investment and thereby explain why innovation in human rabies medication is lagging behind NTDs with a lower burden of disease.

    Full Text Available BACKGROUND : As any other health care workers dentists too are at risk to Blood borne Pathogens. Hence they should be familiar with protocols for the immediate management in case of exposure. It is also necessary to assess the knowledge , attitudes & practices among dentists about methods of disinfection of their instruments and disposal of bio - medical waste generated in dental practice. In view of the public health importance of Blood borne infections like HIV , HBV & HCV and risk posed by them to dentists as well as their patients , the present study was undertaken amongst the dentists pract icing in Private and Government clinics across Goa. AIMS : To document the knowledge , attitude , behavior & practice of dentists in Goa towards blood - borne pathogens and their Post - Exposure Prevention. To assess their adherence to Universal Safety Precaution s , t o validate the need for continuing education and optimize universal safety precautions. Methods and materials – A Cross - sectional study conducted among 107 dentists in Goa selected by systematic random sampling. A questionnaire to assess the knowledge , attitude , behavior & practice of dentists towards blood - borne pathogens and their Post - Exposure Prevention was administered to all the study participants. RESULTS : Although the risk of Blood borne Pathogens to doctors and patients was known by 87.9% of den tists , correct practice of disinfecting used syringes/ needles were not followed by almost half of them. Whereas , correct practice to disinfe ct re - usable dental instruments/ equipment were not followed by majority. Only 75.7% of participants in the study wer e vaccinated for hepatitis B. 98.1% of those dentists with an experience of less than 5years willing to perform treatment on patient with known infection. But none of the dentists in the present study knew all the correct actions to be taken after an accid ental needle - stick injury. CONCLUSIONS : This Study highlights

    This paper systematically reviews epidemiologic studies related to low-level non-occupational exposures to organophosphorus (OP) insecticides. Many of the studies evaluate levels of maternal OP metabolites and subsequent health outcomes in offspring. The studies focused primarily on birth outcomes (e.g., infant body weight or head circumference) and neurodevelopmental (e.g., mental and psychomotor) testing results. The evidence from these studies was reviewed under the Bradford Hill guidelines. Most of the studies assessing exposure based on urinary levels of OP insecticide metabolites used only one or two measurements during pregnancy. The potential for exposure misclassification with this method is largely due to (1) preformed metabolites that are ingested with food, (2) the short elimination half-life of OP insecticides, and (3) lack of specificity to particular OP insecticides for many of the metabolites. For birth outcomes, the majority of reported results are not statistically significant, and the associations are inconsistent within and across studies. There is more within-study consistency for some of the neurodevelopmental testing results, although few associations were examined across several studies. These associations are generally weak, have been replicated only to a limited extent, and require further confirmation before they can be considered established. The OP insecticide levels measured in the epidemiologic studies are too low to cause biologically meaningful acetylcholinesterase inhibition, the most widely used metric for OP insecticide toxicity. Overall, the available evidence does not establish that low-level exposures to OP insecticides cause adverse birth outcomes or neurodevelopmental problems in humans.

    Chronic exposure to non-persistent pesticides (NPPs) is of concern because these substances have been associated with chronic diseases. However, few studies have addressed chronic exposure to NPPs in Spanish populations. We determined the presence of 24 pesticide residues by gas chromatography/mass spectrometry in 363 serum samples obtained from non-occupationally exposed adults from Tenerife island in 2007. Most of the samples (99.45%) showed detectable residues (6 ± 2 pesticides per sample). The most frequently detected pesticides were pyrethrins (96.1%), organophosphates (93.9%) and organochlorines (92.3%). The neurotoxicants bifenthrin and malathion were detected in 81% of the samples and hexachlorobenzene DDT and buprofezin in more than 50%. Malation, an "environmental obesogen", was detected in 82%, and "endocrine disrupter" pesticides were present in 97.2% of the samples. Because there is clear, continuous and inadvertent exposure to NPPs that may be inducing adverse effects on human health, NPPs should be included in biomonitoring studies. Copyright © 2013 SESPAS.

    Objectives Adherence is critical for maximizing the effectiveness of preexposure prophylaxis (PrEP) in preventing HIV infection. Strategies for promoting adherence to HIV treatment, and their potential application to PrEP adherence, have received considerable attention. However, adherence promotion strategies for prevention medications have not been well characterized and may be more applicable to PrEP. We aimed to identify adherence support interventions that have been effective in other prevention fields and could be applied in the HIV prevention context to support pill taking among PrEP users. Methods To identify adherence support interventions that could be evaluated and applied in the PrEP context, we conducted a systematic review across the following prevention fields: hypertension, latent tuberculosis infection, hyperlipidemia, oral contraceptives, osteoporosis, malaria prophylaxis, and post-exposure prophylaxis for HIV infection. We included randomized controlled trials that evaluated the efficacy of interventions to improve adherence to daily oral medications prescribed for primary prevention in healthy individuals or for secondary prevention in asymptomatic individuals. Results Our searches identified 585 studies, of which 48 studies met the eligibility criteria and were included in the review; nine evaluated multiple strategies, yielding 64 separately tested interventions. Interventions with the strongest evidence for improving adherence included complex, resource-intensive interventions, which combined multiple adherence support approaches, and low-cost, low-intensity interventions that provided education or telephone calls for adherence support. Conclusions Our review identified adherence interventions with strong evidence of efficacy across prevention fields and provides recommendations for evaluating these interventions in upcoming PrEP studies.

Venous thromboembolic events are common and potentially life-threatening complications following trauma with an incidence of\t5 to 63%. DVT prophylaxis is essential in the management of trauma patients. Currently, the optimal VTE prophylaxis strategy for trauma patients is unknown. Traditionally, pelvic and lower extremity fractures, head injury, and prolonged immobilization have been considered risk factors for VTE; however it is unclear which combination of risk factors defines a high-risk group. Modalities available for trauma patient thromboprophylaxis are classified into pharmacologic anticoagulation, mechanical prophylaxis, and inferior vena cava (IVC filters. The available pharmacologic agents include low-dose heparin (LDH, low molecular weight heparin (LMWH, and factor Xa inhibitors. Mechanical prophylaxis methods include graduated compression stockings (GCSs, pneumatic compression devices (PCDs, and A-V foot pumps. IVCs are traditionally used in high risk patients in whom pharmacological prophylaxis is contraindicated. Both EAST and ACCP guidelines recommend primary use of LMWHs in trauma patients; however there are still controversies regarding the definitive VTE prophylaxis in trauma patients. Large randomized prospective clinical studies would be required to provide level I evidence to define the optimal VTE prophylaxis in trauma patients.

    Decades after public health interventions - including pre- and post-exposure vaccination - were used to eradicate smallpox, zoonotic orthopoxvirus outbreaks and the potential threat of a release of variola virus remain public health concerns. Routine prophylactic smallpox vaccination of the public ceased worldwide in 1980, and the adverse event rate associated with the currently licensed live vaccinia virus vaccine makes reinstatement of policies recommending routine pre-exposure vaccination unlikely in the absence of an orthopoxvirus outbreak. Consequently, licensing of safer vaccines and therapeutics that can be used post-orthopoxvirus exposure is necessary to protect the global population from these threats. Variola virus is a solely human pathogen that does not naturally infect any other known animal species. Therefore, the use of surrogate viruses in animal models of orthopoxvirus infection is important for the development of novel vaccines and therapeutics. Major complications involved with the use of surrogate models include both the absence of a model that accurately mimics all aspects of human smallpox disease and a lack of reproducibility across model species. These complications limit our ability to model post-exposure vaccination with newer vaccines for application to human orthopoxvirus outbreaks. This review seeks to (1) summarize conclusions about the efficacy of post-exposure smallpox vaccination from historic epidemiological reports and modern animal studies; (2) identify data gaps in these studies; and (3) summarize the clinical features of orthopoxvirus-associated infections in various animal models to identify those models that are most useful for post-exposure vaccination studies. The ultimate purpose of this review is to provide observations and comments regarding available model systems and data gaps for use in improving post-exposure medical countermeasures against orthopoxviruses.

    In semiconductor manufacturing, as the design rule has decreased, the ITRS roadmap requires crucial tighter critical dimension (CD) control. CD uniformity is one of the necessary parameters to assure good performance and reliable functionality of any integrated circuit (IC) [1] [2], and towards the advanced technology nodes, it is a challenge to control CD uniformity well. The study of corresponding CD Uniformity by tuning Post-Exposure bake (PEB) and develop process has some significant progress[3], but CD side to side error happening to some line/space pattern are still found in practical application, and the error has approached to over the uniformity tolerance. After details analysis, even though use several developer types, the CD side to side error has not been found significant relationship to the developing. In addition, it is impossible to correct the CD side to side error by electron beam correction as such error does not appear in all Line/Space pattern masks. In this paper the root cause of CD side to side error is analyzed and the PEB module process are optimized as a main factor for improvement of CD side to side error.

    Poisoning by nerve agents via the percutaneous (p.c.) route is an issue because the slow absorption of agent could result in poisoning which outlasts the protection provided by conventional pharmacological therapy. The bioscavenger approach is based on the concept of binding nerve agent in the bloodstream, thus preventing nerve agent from reaching the target tissues and inhibiting acetylcholinesterase activity. One bioscavenger that has been extensively studied is human butyrylcholinesterase (huBuChE). Protexia® is a pegylated form of recombinant huBuChE. We used a guinea-pig model of p.c. nerve agent poisoning, using an implanted telemetry system to collect physiological data. Guinea-pigs were poisoned with the nerve agent VX (0.74 mg/kg) (∼2.5 × LD₅₀). Two hours following VX exposure, Protexia (72 mg/kg) or saline control was administered intramuscularly. All guinea-pigs treated with Protexia (n=8) survived, compared to no survivors in a saline-treated control group (n=8). Survival following VX and Protexia treatment was associated with minimal incapacitation and observable signs of poisoning, and the mitigation or prevention of the detrimental physiological changes (e.g. seizure, bradycardia and hypothermia) observed in control animals. The opportunity for post-exposure treatment may have utility in both civilian and military scenarios, and this is a promising indication for the use of a bioscavenger.

  17. Tooth brushing for oral prophylaxis

    2014-08-01

    Full Text Available Control of plaque and debris is essential for the prevention of inflammatory periodontal diseases and dental caries, because plaque is the primary etiological factor in the introduction and development of both of these infection-oriented diseases. Plaque removal with a toothbrush is the most frequently used method of oral hygiene. Powered toothbrushes were developed beginning in the 1960s and are now widely used in developed countries. The bristles of a toothbrush should be able to reach and clean efficiently most areas of the mouth, and recently the design of both manual and powered toothbrushes has focused on the ability to reach and clean interproximal tooth surfaces. An individual's tooth brushing behavior, including force, duration, motivation and motion, are also critical to tooth brushing efficacy. Dental floss and the type of toothpaste play additional important roles as auxiliary tools for oral prophylaxis. Dental professionals should help their care-receivers’ meet the requirements of oral hygiene to maintain their QOL. This article reviews these topics.

    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.

    2017-01-01

    Objectives Our purpose is to address whether antimicrobial prophylaxis is necessary before certain dental procedures for patients at increased risk for acquiring infective endocarditis (IE). Methods We reviewed recommendations for IE prophylaxis made by the American Heart Association (AHA) from 1995 to the present time. We also compared and contrasted the current recommendations from the AHA, European Society of Cardiology (ESC), United Kingdom’s National Institute for Health and Care Excellence (NICE) and a consortium of French organisations. We further reviewed recent papers that have observed the incidence of IE since these current recommendations were published. Results Beginning in the 1990s, questions were raised about the advisability of using antimicrobial prophylaxis before certain dental procedures to prevent IE. Various groups in Europe and the US were increasingly aware that there were not any clinical trials showing the effectiveness, or lack thereof, of such prophylaxis. In the early to mid-2000s, the AHA, ESC and French consortium published guidelines recommending restriction of prophylaxis before dental procedures to patients with highest risk for developing IE and/or the highest risk for an adverse outcome from IE. The NICE guidelines eliminated recommendations for prophylaxis before dental procedures. Studies published after these changes were instituted have generally shown that the incidence of IE has not changed, although two recent reports have observed some increased incidence (but not necessarily related to an antecedent dental procedure). Conclusion A multi-national randomised controlled clinical trial that would include individuals from both developed and developing countries around the world is needed to ultimately define whether there is a role for antibiotic prophylaxis administered before certain dental procedures to prevent IE.

    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 BACKGROUND: Imported cases threaten rabies reemergence in rabies-free areas. During 2000-2005, five dog and one human rabies cases were imported into France, a rabies-free country since 2001. The Summer 2004 event led to unprecedented media warnings by the French Public Health Director. We investigated medical practice evolution following the official elimination of rabies in 2001; impact of subsequent episodic rabies importations and national newspaper coverage on demand for and delivery of antirabies prophylaxis; regular transmission of epidemiological developments within the French Antirabies Medical Center (ARMC network; and ARMC discussions on indications of rabies post-exposure prophylaxis (RPEP. METHODOLOGY/PRINCIPAL FINDINGS: Annual data collected by the National Reference Center for Rabies NRCR (1989-2006 and the exhaustive database (2000-2005 of 56 ARMC were analyzed. Weekly numbers of patients consulting at ARMC and their RPEP- and antirabies-immunoglobulin (ARIG prescription rates were determined. Autoregressive integrated moving-average modeling and regression with autocorrelated errors were applied to examine how 2000-2005 episodic rabies events and their related national newspaper coverage affected demand for and delivery of RPEP. A slight, continuous decline of rabies-dedicated public health facility attendance was observed from 2000 to 2004. Then, during the Summer 2004 event, patient consultations and RPEP and ARIG prescriptions increased by 84%, 19.7% and 43.4%, respectively. Moreover, elevated medical resource use persisted in 2005, despite communication efforts, without any secondary human or animal case. CONCLUSIONS: Our findings demonstrated appropriate responsiveness to reemerging rabies cases and effective newspaper reporting, as no secondary case occurred. However, the ensuing demand on medical resources had immediate and long-lasting effects on rabies-related public health resources and expenses. Henceforth, when

    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.

    Full Text Available Despite major advances in HIV therapy, the number of new HIV infections remains very high, even in high-income countries where resurgence among men who have sex with men (MSM has been witnessed. New prevention strategies have therefore to be assessed in order to curb the incidence of HIV infection. Recent studies have explored the effectiveness of antiretroviral therapy (ART for HIV prevention and have generally yielded encouraging results. ART has been used successfully to prevent mother-to-child transmission of HIV, HIV acquisition following occupational or sexual exposure to HIV (post-exposure prophylaxis, and more recently, to reduce the risk of HIV transmission within a serodiscordant couple by treating the HIV-positive partner (HPTN 052 study. Another possible use of ART in prevention is pre-exposure prophylaxis, where ART is taken by an HIV-seronegative individual before HIV exposure. This PrEP strategy has been validated in animal models and more recently assessed in clinical trials in humans. The results of six large efficacy trials of PrEP are now available, but results have been inconsistent. The use of tenofovir gel in women at higher risk in Sub-Saharan Africa has shown efficacy when given before and after sex in the Caprisa 004 study (reduction of 39% of the incidence of HIV, whereas no efficacy was shown with daily use in the VOICE trial. Similarly, daily oral PrEP with tenofovir or tenofovir and emtricitabine has proved effective in the Iprex trial in MSM (reduction of 42% of HIV incidence, in the Partners PrEP study (reduction of 67 to 75% in HIV incidence and in the TDF-2 trial (reduction of 63% in HIV incidence, but not in the Fem-PrEP or the VOICE trials in women. There are many potential explanations for these apparently conflicting results, such as the populations in which these strategies have been assessed, the differential pharmacokinetics of ART in the male and female genital tracts and most likely the high level of

    To calculate and compare the direct medical costs of guideline-recommended prophylaxis with prophylaxis that does not fully adhere with guideline recommendations in a large, real-world population. Discharge records were retrieved from the US Premier Perspective™ database (January 2003-December 2003) for patients aged≥40 years with a primary diagnosis of cancer, chronic heart failure, lung disease, or severe infectious disease who received some form of thromboprophylaxis. Univariate analysis and multivariate regression modeling were performed to compare direct medical costs between discharges who received appropriate prophylaxis (correct type, dose, and duration based on sixth edition American College of Chest Physicians [ACCP] recommendations) and partial prophylaxis (not in full accordance with ACCP recommendations). Market segmentation analysis was used to compare costs stratified by hospital and patient characteristics. Of the 683 005 discharges included, 148,171 (21.7%) received appropriate prophylaxis and 534,834 (78.3%) received partial prophylaxis. The total direct unadjusted costs were $15,439 in the appropriate prophylaxis group and $17,763 in the partial prophylaxis group. After adjustment, mean adjusted total costs per discharge were lower for those receiving appropriate prophylaxis ($11,713; 95% confidence interval [CI], $11,675-$11,753) compared with partial prophylaxis ($13,369; 95% CI, $13,332-$13 406; Panalysis suggests that appropriate prophylaxis, in adherence with ACCP guidelines, is potentially cost-saving compared with partial prophylaxis in at-risk medical patients.

    Venous thromboembolism ( VTE), which is manifested as deep vein thrombosis (DVT) and pulmonary embolism (PE), represents a significant cause of death, disability,and discomfort. They are frequent complications of various surgical procedures. The aging population and the survival of more severely injured patients may suggest an increasing risk of thromboembolism in the trauma patients. Expanded understanding of the population at risk challenges physicians to carefully examine risk factors for VTE to identify high-risk patients who can benefit from prophylaxis. An accurate knowledge of evidence-based risk factors is important in predicting and preventing postoperative DVT, and can be incorporated into a decision support system for appropriate thromboprophylaxis use.Standard use of DVT prophylaxis in a high-risk trauma population leads to a low incidence of DVT. The incidence of VTE is common in Asia. The evaluation includes laboratory tests, Doppler test and phlebography. Screening Doppler sonography should be performed for surveillance on all critically injured patients to identify DVT. D-Dimer is a useful marker to monitor prophylaxis in trauma surgery patients. The optimal time to start prophylaxis is between 2 hours before and 10 hours after surgery, but the risk of PE continues for several weeks. Thromboprophylaxis includes graduated compression stockings and anticoagulants for prophylaxis. Anticoagulants include Warfarin, which belongs to Vitamin K antagonists, unfractionated heparin,low molecular weight heparins, factor Xa indirect inhibitor Fondaparinux, and the oral Ⅱa inhibitor Melagatran and ximelagatran. Recombinant human soluble thrombomodulin is a new and highly effective antithrombotic agent. Prophylactic placement of vena caval filters in selected trauma patients may decrease the incidence of PE. The indications for prophylactic inferior vena cava filter insertion include prolonged immobilization with multiple injuries, closed head injury, pelvic

    The safety and timing of venous thromboembolism (VTE) prophylaxis in patients with blunt splenic injuries is not well known. We hypothesized that early initiation of VTE prophylaxis does not increase failure of nonoperative management or transfusion requirements in these patients. A retrospective review of trauma patients with blunt splenic injury was performed. Patients were compared based on initiation and timing of VTE prophylaxis (72 hours). Patients who received VTE prophylaxis were matched with those who did not. Primary outcomes included were operation or angioembolization. A total of 497 patients (256 received VTE prophylaxis and 241 did not) were included. There was no difference in the number of interventions based on presence of or time to VTE prophylaxis initiation. Early initiation (<48 hours) of VTE prophylaxis is safe in patients with blunt splenic injuries treated nonoperatively, and may be safe as early as 24 hours. Copyright © 2016 Elsevier Inc.

  14. Polymorphism of Glutathione S-transferase T1, M1 and P1 Genes in a Shanghai Population: Patients With Occupational or Non-occupational Bladder Cancer

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Objective Glutathione S-transferases are involved in the conjugation of xenobiotics. To explore whether GSTs polymorphisms are involved in the development of occupational or non-occupational bladder cancer, polymorphism frequencies of GSTT1, M1 and P1 were investigated in a normal population, which had been settled in a rural area in Shanghai suburb for at least 5 generations as well as in a group of patients with benzidine exposure related occupational bladder cancer in Shanghai dyestuff industry and a group of patients with non-occupational bladder cancer. Methods PCR based procedures were performed in the study populations to confirm the genotypes of GSTT1, M1 and P1. Results The polymorphisms at locus of GSTP1- A1578G in the normal population differed significantly from those in Caucasians or African Americans. All the subjects genotyped so far (n =118) bore only homogenous wild genotype (C2293/ C2293) at GSTP1 - C2293T locus. This locus seemed to be a monomorphic in Shanghai population. No significant difference in GSTT1 and GSTM1 polymorphic form frequencies could be confirmed among three groups of subjects. An overrepresentation of GSTP1 AG or GG genotype corresponding a less stable and less effective isozyme protein was detected in patients with benzidine related occupational bladder cancer, compared with that in the normal population though a statistical significance was not yet reached (P=0.09, OR=1.96, 95% CI 0.89-4.32,). Conclusion This study suggests that GSTM1 or GSTT1 homozygous deficiency genotypes and their combination do not have a clear impact on bladder cancer incidence in a Shanghai population. It seems that GSTP1 polymorphism is not associated with non-occupational bladder cancer. GSTP1 AG or GG genotype has a higher frequency in the patients with benzidine related occupational bladder cancer, and further work is needed to confirm if GSTP1 AG or GG genotype plays a role in the development of occupational bladder cancer.

    Endosulfan is a persistent organic pollutant (POP) that has lethal and sublethal effects on non-target organisms, including amphibians. In a laboratory study, we investigated direct and post-exposure effects of endosulfan on Bufo bufo tadpoles. For this purpose we exposed the tadpoles to a single short-term contamination event (96 h) at an environmentally-realistic concentration (200 μg endosulfan/L). This was followed by a recovery period of 10 days when the experimental animals were kept in pesticide-free water. The endpoints were assessed in terms of mortality, incidence of deformity, effects on behavior, and the morpho-functional features of the epidermis. We found that a short-term exposure to the tested concentration of endosulfan did not cause mortality but induced severe sublethal effects, such as hyperactivity, convulsions, and axis malformations. Following relocation to a pesticide-free environment, we noted two types of response within the experimental sample, in terms of morphological and behavioral traits. Moreover, by using both ultrastructural and a morpho-functional approach, we found that a short-term exposure to endosulfan negatively affected the amphibian epidermis. We also observed several histo-pathological alterations: increased mucous secretion, an increase in intercellular spaces and extensive cell degeneration, together with the induction of an inducible isoform of nitric oxide synthase (iNOS). Following the post-exposure period, we found large areas of epidermis in which degeneration phenomena were moderate or absent, as well as a further increase in iNOS immunoreactivity. Thus, after 10 days in a free-pesticide environment, the larval epidermis was able to partially replace elements that had been compromised due to a physiological and/or a pathological response to the pesticide. These results highlight the need for both exposure and post-exposure experiments, when attempting to assess pollutant effects.

    2010-10-01

    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.

  19. Historical Review: Problematic Malaria Prophylaxis with Quinine.

    Science.gov (United States)

    Shanks, G Dennis

    2016-08-03

    Quinine, a bitter-tasting, short-acting alkaloid drug extracted from cinchona bark, was the first drug used widely for malaria chemoprophylaxis from the 19th century. Compliance was difficult to enforce even in organized groups such as the military, and its prophylaxis potential was often questioned. Severe adverse events such as blackwater fever occurred rarely, but its relationship to quinine remains uncertain. Quinine prophylaxis was often counterproductive from a public health viewpoint as it left large numbers of persons with suppressed infections producing gametocytes infective for mosquitoes. Quinine was supplied by the first global pharmaceutical cartel which discouraged competition resulting in a near monopoly of cinchona plantations on the island of Java which were closed to Allied use when the Japanese Imperial Army captured Indonesia in 1942. The problems with quinine as a chemoprophylactic drug illustrate the difficulties with medications used for prevention and the acute need for improved compounds.

    Venous thromboembolism (VTE), a deep and superficial thrombosis and pulmonary embolism, is a very important problem of severe stroke. Pulmonary embolism (PE) significantly influences the course and outcome of severe stroke. The cause of this effect lies not only in severe patient's condition, high risk of VTE and difficulties in diagnosis of VTE but in still common limits in prophylaxis and treatment of PE in severe stroke, first of all, in brain hemorrhages and large brain infarctions with secondary hemorrhage. The paper presents the main principles and methods of prophylaxis of VTE in severe stroke. The suggested approach allows to decrease the frequency of VTE and fatal outcomes in severe stroke in the modern neuro-intensive care units.

    Petty, John K

    2017-02-01

    Although venous thromboembolism (VTE) occurs in less than 1% of hospitalized pediatric trauma patients, care providers must make decisions about VTE prophylaxis on a daily basis. The consequences of VTE are significant; the risks of developing VTE are variable; and the effectiveness of prophylaxis against VTE is not conclusive in children. While the value of VTE prophylaxis is well defined in adult trauma care, it is unclear how this translates to the care of injured children. This review evaluates the incidence and risks of VTE in pediatric trauma and assesses the merits of prophylaxis in children. Pharmacologic prophylaxis against VTE is a reasonable strategy in critically injured adolescent trauma patients. Further study is needed to establish the risks and benefits of VTE prophylaxis across the spectrum of injured children. Copyright © 2017 Elsevier Inc. All rights reserved.

    The highly toxic organophosphorus (OP) nerve agent VX is characterized by a remarkable biological persistence which limits the effectiveness of standard treatment with atropine and oximes. Existing OP hydrolyzing enzymes show low activity against VX and hydrolyze preferentially the less toxic P(+)-VX enantiomer. Recently, a phosphotriesterase (PTE) mutant, C23, was engineered towards the hydrolysis of the toxic P(-) isomers of VX and other V-type agents with relatively high in vitro catalytic efficiency (kcat/KM=5×10(6)M(-1)min(-1)). To investigate the suitability of the PTE mutant C23 as a catalytic scavenger, an in vivo guinea pig model was established to determine the efficacy of post-exposure treatment with C23 alone against VX intoxication. Injection of C23 (5mgkg(-1) i.v.) 5min after s.c. challenge with VX (∼2LD50) prevented systemic toxicity. A lower C23 dose (2mgkg(-1)) reduced systemic toxicity and prevented mortality. Delayed treatment (i.e., 15min post VX) with 5mgkg(-1) C23 resulted in survival of all animals and only in moderate systemic toxicity. Although C23 did not prevent inhibition of erythrocyte acetylcholinesterase (AChE) activity, it partially preserved brain AChE activity. C23 therapy resulted in a rapid decrease of racemic VX blood concentration which was mainly due to the rate of degradation of the toxic P(-)-VX enantiomer that correlates with the C23 blood levels and its kcat/KM value. Although performed under anesthesia, this proof-of-concept study demonstrated for the first time the ability of a catalytic bioscavenger to prevent systemic VX toxicity when given alone as a single post-exposure treatment, and enables an initial assessment of a time window for this approach. In conclusion, the PTE mutant C23 may be considered as a promising starting point for the development of highly effective catalytic bioscavengers for post-exposure treatment of V-agents intoxication.

    HIV-testing algorithms for preexposure prophylaxis (PrEP) should be optimized to minimize the risk of drug resistance, the time off PrEP required to evaluate false-positive screening results, and costs and to expedite the start of therapy for those confirmed to be infected. HIV rapid tests (RTs) for anti-HIV antibodies provide results in less than 1 h and can be conducted by nonlicensed staff at the point of care. In many regions, Western blot (WB) testing is required to confirm reactive RT r...

    A meta-analysis was conducted to evaluate the association between non-occupational physical activity (PA) during pregnancy and the risk of preterm birth (PTB). By searching PubMed and EMBASE from inception to August 20, 2016, 25 observational studies (18 cohorts and 7 case-controls) and 12 interventional studies were identified. Comparing the highest to the lowest category of leisure-time PA during pregnancy, the pooled relative risk (RR) of PTB was 0.83 [95% confidence interval (CI) = 0.74–0.93] for cohort studies and 0.60 (95% CI = 0.43–0.84) for case-control studies. No overall significant association was found between domestic or commuting PA and the risk of PTB. In addition, PA intervention did not indicate significant beneficial effect on the risk of PTB. Evidence from the observational studies suggested that leisure-time, but not domestic or commuting, PA during pregnancy was inversely associated with the risk of PTB. The findings were not supported by small-scale and short-term interventional studies. Further research with objective measurement on leisure-time PA is warranted. PMID:28327589

  5. Attitudes toward infection prophylaxis in pediatric oncology: a qualitative approach.

    Full Text Available BACKGROUND: The risks and benefits of infection prophylaxis are uncertain in children with cancer and thus, preferences should be considered in decision making. The purpose of this report was to describe the attitudes of parents, children and healthcare professionals to infection prophylaxis in pediatric oncology. METHODS: THE STUDY WAS COMPLETED IN THREE PHASES: 1 An initial qualitative pilot to identify the main attributes influencing the decision to use infection prophylaxis, which were then incorporated into a discrete choice experiment; 2 A think aloud during the discrete choice experiment in which preferences for infection prophylaxis were elicited quantitatively; and 3 In-depth follow up interviews. Interviews were recorded verbatim and analyzed using an iterative, thematic analysis. Final themes were selected using a consensus approach. RESULTS: A total of 35 parents, 22 children and 28 healthcare professionals participated. All three groups suggested that the most important factor influencing their decision making was the effect of prophylaxis on reducing the chance of death. Themes of importance to the three groups included antimicrobial resistance, side effects of medications, the financial impact of outpatient prophylaxis and the route and schedule of administration. CONCLUSION: Effect of prophylaxis on risk of death was a key factor in decision making. Other identified factors were antimicrobial resistance, side effects of medication, financial impact and administration details. Better understanding of factors driving decision making for infection prophylaxis will help facilitate future implementation of prophylactic regiments.

    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.

    This study was conducted to determine the optimum dose of supplemental iron for prophylaxis against pregnancy anemia. One hundred and ten pregnant women were randomly allocated to three groups: Group A receiving equivalent of 60 mg, group B 120 mg and Group C 240 mg, elemental iron as ferrous sulphate daily; the content of folic acid was constant in all the three groups (0.5 mg). These women had at least consumed 90 tablets in 100 +/- 10 days. Blood was drawn at the beginning and at the end of the treatment. Fifty percent were anemic (less than 11 g/100 ml). The hemoglobin levels rose similarly in all groups and the differences were statistically not significant. Fifty-six percent had depleted iron stores (serum ferritin value less than 12 micrograms/l) at the beginning of the study. Following therapy a statistically significant increase in iron stores was observed in group B and C as compared to group A. The difference between group B and C was not significant. The side effects increased with increasing doses of iron; 32.4%, 40.3% and 72% in group A, B and C respectively. Based on these findings, the authors advocate that optimum dose of iron should be 120 mg instead of 60 mg as is currently being used in the National Nutritional Anemia Prophylaxis Programme.

    2013-01-01

    Long-term prophylactic antibiotics are being widely implemented as primary or adjunctive therapy in primary immune deficiencies. This practice has transformed clinical outcomes in the setting of chronic granulomatous disease, complement deficiencies, Mendelian susceptibility to mycobacterial disease, Wiskott-Aldrich syndrome, hyper-IgE syndrome, Toll signaling defects, and prevented Pneumocystis in patients with T-cell deficiencies. Yet, controlled trials are few in the context of primary antibody deficiency syndromes, and most of this practice has been extrapolated from data in patients who are immune competent and with recurrent acute otitis media, chronic rhinosinusitis, cystic fibrosis, and bronchiectasis. The paucity of guidelines on the subject is reflected in recent surveys among practicing immunologists that highlight differences of habit regarding this treatment. Such discrepancies reinforce the lack of standard protocols on the subject. This review will provide evidence for the use of antibiotic prophylaxis in various primary immune deficiency populations, especially highlighting the role antibiotic prophylaxis in primary antibody deficiency syndromes. We also discussed the relationship of long-term antibiotic use and the prevalence of resistant pathogens. Overall, examination of available data on the use of prophylactic antibiotics in antibody deficiency syndromes merit future investigation in well-designed multicenter prospective trials because this population has few other management options.

    Of 3533 Rh-negative women who began a pregnancy without detectable Rh antibodies, 62 (1.8%) demonstrated evidence of Rh isoimmunization during pregnancy or within 3 days after delivery. All denied transfusions as well as abortions or previous pregnancies not followed by the administration of Rh immune globulin. Rh isoimmunization during pregnancy or within 3 days after delivery, which will not be prevented by the administration of Rh immune globulin after delivery, is the most important cause of residual Rh isoimmunization. A clinical trial of antenatal administration of Rh immune globulin, initially at 34 weeks's and subsequently at 28 and 34 weeks' gestation, in 1357 Rh-negative pregnant women who were delivered of Rh-positive babies, was effective in preventing the development of Rh isoimmunization during pregnancy or within 3 days after delivery. Antenatal prophylaxis with Rh immune globulin will be necessary if the incidence of Rh isoimmunization is to be reduced to its lowest possible level. Antenatal prophylaxis at 28 weeks' gestation is now an insured service in Manitoba.

    Full Text Available Occupational exposures predispose health workers (HWs to a risk of HIV infection. When properly used, HIV Post Exposure Prophylaxis (PEP can significantly reduce this risk. Th purpose of this study was to determine the extent and types of occupational exposures, availability of PEP guidelines, and utilisation of PEP amongst HWs. A cross-sectional mixed methods baseline study was conducted between March and May 2014 using a structured questionnaire administered to 236 HWs from Shinyanga, Sengerema and Musoma hospitals in Tanzania. Relationships between variables were determined using the chi-square test. Qualitative data was gathered during interviews with key informants and walkthrough observations in the hospital wards, and analysed using the framework method. Majority of respondents were nurses (53%, over 40 years old (61% with more than 20 years (40% of hospital experience. Needle stick and sharp injuries were experienced by 31% of respondents whilst 26% experienced splashes. Only 28% of splashes were reported compared to 80% and 68% of needle sticks and sharp injuries, respectively. Those who experienced needle sticks were more likely to report the incident (p < 0.001, receive testing (p < 0.003 or PEP (p = 0.005. Although 66% reported the availability of PEP guidelines, only 39% of exposed HWs received PEP. Occupational exposures are common in these hospitals. HWs under-report and suboptimally use PEP services. Health worker safety programmes should establish functional systems for reporting and adherence to PEP procedures. Future research should establish factors that determine compliance with PEP procedures.

    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.

    2014-01-01

    The relevance of aerosinusitis stems from the high number of flight passengers and the impaired fitness for work of the flight personnel. The frontal sinus is more frequently affected than the maxillary sinus and the condition generally occurs during descent. Sinonasal diseases and anatomic variations leading to obstruction of paranasal sinus ventilation favor the development of aerosinusitis. This Continuing Medical Education (CME) article is based on selective literature searches of the PubMed database (search terms: "aerosinusitis", "barosinusitis", "barotrauma" AND "sinus", "barotrauma" AND "sinusitis", "sinusitis" AND "flying" OR "aviator"). Additionally, currently available monographs and further articles that could be identified based on the publication reviews were also included. Part 1 presents the pathophysiology, symptoms, risk factors, epidemiology and prophylaxis of aerosinusitis. In part 2, diagnosis, conservative and surgical treatment will be discussed.

    2014-05-01

    Combination therapy with beta-blockers and endoscopic band ligation (EBL) is the standard prophylaxis of esophageal variceal rebleeding in cirrhosis. Beta-blockers are the backbone of combination therapy, since their benefit extend to other complications of portal hypertension. EBL carries the risk of post-banding ulcer bleeding, which explains why overall rebleeding is reduced when beta-blockers are added to EBL, and not when EBL is added to beta-blockers. TIPS is the rescue treatment, but it could be considered as first choice in patients that first bleed while on beta-blockers, those with contraindications to beta-blockers or with refractory ascites, and those with fundal varices.

    60 minutes after i.v. injection tissue levels of 7 different cephalosporins were obtained using biological assay. The following concentrations were measured: cephalothn 1.4 micrograms/g; cepharin 4.7 micrograms/g; cephacetrile 11.2 micrograms/g; cephradine 15.4 micrograms/g; cefazedone 26.9 micrograms/g; cefamandole 40.3 micrograms/g, and finally cefoxitin 43 micrograms/g. The high tissue levels of cefamandole and cefoxitin are especially remarkable as i.v. doses of both antibiotics had been 50 mg/kg body weight ( doses of all other cephalosporins 100 mg/kg body weight). Except cephalothin, all cephalosporins tested were suitable for antibiotic prophylaxis in cardiac surgery.

    To compare the costs associated with adjunctive azithromycin compared with standard cefazolin antibiotic prophylaxis alone for unscheduled and scheduled cesarean deliveries. A decision analytic model was created to compare cefazolin alone with azithromycin plus cefazolin. Published incidences of surgical site infection after cesarean delivery were used to estimate the baseline incidence of surgical site infection in scheduled and unscheduled cesarean delivery using standard antibiotic prophylaxis. The effectiveness of adjunctive azithromycin prophylaxis was obtained from published randomized controlled trials for unscheduled cesarean deliveries. No randomized study of its use in scheduled procedures has been completed. Cost estimates were obtained from published literature, hospital estimates, and the Healthcare Cost and Utilization Project and considered costs of azithromycin and surgical site infections. A series of sensitivity analyses were conducted by varying parameters in the model based on observed distributions for probabilities and costs. The outcome was cost per cesarean delivery from a health system perspective. For unscheduled cesarean deliveries, cefazolin prophylaxis alone would cost $695 compared with $335 for adjunctive azithromycin prophylaxis, resulting in a savings of $360 (95% CI $155-451) per cesarean delivery. In scheduled cesarean deliveries, cefazolin prophylaxis alone would cost $254 compared with $111 for adjunctive azithromycin prophylaxis, resulting in a savings of $143 (95% CI 98-157) per cesarean delivery, if proven effective. These findings were robust to a multitude of inputs; as long as adjunctive azithromycin prevented as few as seven additional surgical site infections per 1,000 unscheduled cesarean deliveries and nine additional surgical site infections per 10,000 scheduled cesarean deliveries, adjunctive azithromycin prophylaxis was cost-saving. Adjunctive azithromycin prophylaxis is a cost-saving strategy in both unscheduled

    Full Text Available Problem statement: We studied in detail a case in which a nurse caring for an HIV-infected child suffered a deep-laceration accident with contaminated blood. Approach: The patient had been treated with zidovudine (ZDV and the nurse became infected despite prophylactic use of ZDV initiated 2 h after the accident. A reactive anti-HIV-1/2 EIA and an indeterminate western blot (gp120/160 reactivity were obtained from the nurse on the day of the accident, suggesting pre-exposure infection. However, a negative western blot and positive DNA PCR were documented 10 days after the accident and seroconversion occurred an additional two weeks later. Results: Phylogenetic analyses of HIV-1 tat and C2-C4-gp120 env regions confirmed that the nurse infected by two different HIV-1 strains present in the child. Strains present in both subjects revealed multi-nucleoside resistant HIV-1. Dilutional serological studies using 10 HIV-infected patients’ sera demonstrated that passive seroreactivity could occur with infusion of less than 1 uL of blood when highly sensitive assays are employed. Conclusion: This is the first well-documented case of passive HIV antibody detection after a percutaneous exposure. Reactive baseline serology should not be assumed to represent prior infection nor exclude prophylaxis. Transmission of drug-resistant HIV-1 corroborates the medical history and supports use of drug history and resistance testing to guide antiretroviral prophylaxis.

    The anticancer drugs are getting increasing attention as an emerging contaminant in the aquatic environments. In the present study, feeding behavior of the rotifer Brachionus calyciflorus under the impact of anticancer drug imatinib was evaluated. Traditional toxicological studies usually focus on dose-effect relationship at a given exposure time, while ignore the possible impact after the exposure. Thus, how the impact varied in the post-exposure and re-exposure was also considered in the present study. The feeding depression of the rotifers was attributed to the increased concentration of imatinib. Although the filtration and ingestion rate of the rotifers recovered to a certain extent after the exposure, the significant feeding inhibition still persisted even if the exposure was ended. In the re-exposure period, the feeding behavior was less depressed than those of the exposure period, which implied that rotifers might develop a tolerance to the same toxics. The activities of acetylcholine esterase (AchE) and the levels of reactive oxygen species (ROS) in rotifers were also detected. Imatinib inhibited the activities of AchE in the exposure and re-exposure while ROS levels increased significantly in the re-exposure period. Our present study provided an integrated assessment the potential environmental risks of imatinib at a new perspective. Copyright © 2017 Elsevier Ltd. All rights reserved.

    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.

Materials and Methods: The were 38 active stem cell transplantation centers in Turkey, 28 of which were registered with the European Group for Blood and Marrow Transplantation (EBMT. Survey questionnaires were sent to the 28 EBMT centers in an effort to collect data on antifungal prophylaxis in different settings. In all, 24 of the centers completed the survey; 1 of the 24 centers was excluded from the study, as it was under construction at the time and was not performing transplantation.Results: In all, 15 (65% of the 23 centers were adult SCT centers, 7 (31% were pediatric SCT centers, and 1 center treated both adult and pediatric patients. All centers (23/23 performed both allogeneic and autologous transplants, 20 centers performed non-myeloablative transplants, 8 performed cord blood transplants, and 7 performed unrelated transplants. Primary antifungal prophylaxis was used at all 23 centers during allogeneic transplants, whereas 18 of the 23 centers used it during every autologous transplant and 2 of the 23 centers used it during autologous transplants on a per case basis. The most common drug used for prophylaxis was fluconazole (F (21/23, followed by itraconazole (I (3/23, amphotericin-B (2/23, and posaconazole (1/23. Among the 23 centers, 3 reported that for allogenic transplants they changed the antifungal prophylactic in cases of graft versus host disease (GVHD, and 12 of the 23 centers reported that they changed the antifungal prophylactic in case of nearby construction. All 23 centers performed secondary prophylaxis. Conclusion: Antifungal prophylaxis for hematopoetic SCT patients was the standard protocol in the 23 centers included in the study, usually with such azoles as F.

    The extent to which prescribed antimicrobial prophylaxis against bacterial endocarditis conformed with American Heart Association (AHA) guidelines was determined and the frequency of nonconformity with specific elements of the guidelines was evaluated. Patients with conditions defined by AHA as placing them at risk for developing endocarditis were identified through medical records for a four-year period at an 850-bed hospital. Data about the procedures they underwent and prophylaxis prescribed were compared with the AHA guidelines. Conformity with the guidelines was evaluated according to whether prophylaxis was recommended, optional, or unnecessary; nonconformity with specific elements of the guidelines (indication, choice of antimicrobial, dose, dosage interval, timing, and duration) was also evaluated. The following variables were evaluated for possible association with nonconformity to the guidelines: patient's age and sex, penicillin allergy, use of a consultant, and whether the procedure was the first performed in the patient after identification of the cardiac condition. Of the 131 cases analyzed, 29 (22%) involved prophylaxis that conformed with the AHA guidelines. Conformity with the guidelines was significantly lower when prophylaxis was recommended or optional than when it was unnecessary. Nonconformity was most common with the following elements: indication, choice of antimicrobial, and dose. Recommended prophylaxis was given more often in children than in adults and more often before first procedures than before subsequent procedures. More of the regimens prescribed for children exceeded the recommended duration than those prescribed for adults. Unnecessary prophylaxis was given more often when a consultant was involved than when no consultant was involved. In hospitalized patients, conformity with AHA guidelines for antimicrobial prophylaxis against endocarditis was low.

    Antifungal prophylaxis is routinely given to patients with hematologic malignancies at high risk for invasive fungal infections (IFI), yet breakthrough IFI may still occur. Posaconazole emerged as an excellent alternative for fungal prophylaxis in high-risk patients. There is limited data about pharmacokinetics and plasma concentrations of posaconazole when given as prophylaxis in patients with hematologic malignancies. We recruited 20 adult patients for prospective, open label trial of posaconazole given as a prophylaxis in patients with newly diagnosed acute myeloid leukemia (AML) undergoing induction chemotherapy or first salvage therapy. The median age of all patients was 65 years and received prophylaxis for a median of 38 days (range: 5-42 days).Ten patients (50%) completed 42 days on posaconazole prophylaxis. Median plasma posaconazole levels showed no statistical difference across gender, body surface area, patients developing IFI, and patients acquiring grade 3 or 4 elevation of liver enzymes. However, there was an overall trend for higher trough concentrations among patients with no IFI than those with IFI. Pharmacokinetics of posaconazole varies from patient to patient, and AML patients receiving induction chemotherapy who never develop IFI tend to have higher plasma concentrations after oral administration of posaconazole.

    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.

    Full Text Available Domenico D’Amico1, Stewart J Tepper21Headache Center, Department of Neurological Sciences, C Besta Neurological Institute, Milan, Italy; 2Center for Headache and Pain, Neurological Institute, Cleveland Clinic Foundation, Cleveland, Ohio, USAAbstract: Migraine is a chronic neurological condition with episodic exacerbations. Migraine is highly prevalent, and associated with significant pain, disability, and diminished quality of life. Migraine management is an important health care issue. Migraine management includes avoidance of trigger factors, lifestyle modifications, non-pharmacological therapies, and medications. Pharmacological treatment is traditionally divided into acute or symptomatic treatment, and preventive treatment or prophylaxis. Many migraine patients can be treated using only acute treatment. Patients with severe and/or frequent migraines require long-term preventive therapy. Prophylaxis requires daily administration of anti-migraine compounds with potential adverse events or contraindications, and may also interfere with other concurrent conditions and treatments. These problems may induce patients to reject the idea of a preventive treatment, leading to poor patient adherence. This paper reviews the main factors influencing patient acceptance of anti-migraine prophylaxis, providing practical suggestions to enhance patient willingness to accept pharmacological anti-migraine preventive therapy. We also provide information about the main clinical characteristics of migraine, and their negative consequences. The circumstances warranting prophylaxis in migraine patients as well as the main characteristics of the compounds currently used in migraine prophylaxis will also be briefly discussed, focusing on those aspects which can enhance patient acceptance and adherence.Keywords: migraine, prophylaxis, preventive therapy, acceptance, adherence

    Rios, Juliana Ferreira da Silva; Camargos, Paulo Augusto Moreira; Corrêa, Luísa Petri; Romanelli, Roberta Maia de Castro

    This article aims to review the use of antifungal prophylaxis with intravenous fluconazole in premature newborns and the occurrence of Invasive Candidiasis. 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.

Material and methods. 190 women with osteopenia of spine and/or femoral neck aged 50 to 70 years (mean 60,6±5 years were followed up during a year. Different modes of prophylaxis were applied. 59 pts of group 1 received Calcium D3 Nicomed 2 tablets a day, 25 pts of group 2 - Vitrum Osteomag 2 tablets a day, 46 pts of group 3 - calcium carbonate 2500 mg/day, 60 pts of control group received recommendations about diet and physical activity. Results. 3,5% from 114 pts examined had normal 25(OHD blood level while 23% showed deficiency of vitamin D. Mean calcium consumption with milk products was 350 mg/day. Bone mineral density (BMD significantly increased on 1,6-1% in pts older than 60 years receiving Vitrum Osteomag and Calcium D3 Nicomed respectively while younger pts did not show such changes. BMD in pts olderthan 60 years receiving calcium carbonate increased on 0,5% but this difference was not significant. Tolerability of all 3 drugs was comparable.

    HIV-testing algorithms for preexposure prophylaxis (PrEP) should be optimized to minimize the risk of drug resistance, the time off PrEP required to evaluate false-positive screening results, and costs and to expedite the start of therapy for those confirmed to be infected. HIV rapid tests (RTs) for anti-HIV antibodies provide results in less than 1 h and can be conducted by nonlicensed staff at the point of care. In many regions, Western blot (WB) testing is required to confirm reactive RT results. WB testing, however, causes delays in diagnosis and adds expense. The iPrEx study evaluated the safety and efficacy of daily oral emtricitabine-tenofovir disoproxil fumarate among HIV-seronegative men and transgender women who have sex with men: HIV infection was assessed with two RTs plus WB confirmation, followed by HIV-1 plasma viral load testing. During the iPrEx study, there were 51,260 HIV status evaluations among 2,499 volunteers using RTs: 142 (0.28%) had concordant positive results (100% were eventually confirmed) and 19 (0.04%) had discordant results among 14 participants; 11 were eventually determined to be HIV infected. A streamlined approach using only one RT to screen and a second RT to confirm (without WB) would have had nearly the same accuracy. Discrepant RT results are best evaluated with nucleic acid testing, which would also increase sensitivity. PMID:25378570

    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

    Full Text Available The prevalence of trimethoprim (TMP and sulfamethoxazole (SMX resistance in commensal E. coli from pigs was tested in this study. E. coli was derived from three groups of piglets in successive stages of metaphylactic therapy and from two groups of sows 10 and 18 weeks after the treatment. MIC values of TMP and SMX were determined for a total of 352 strains. The presence of resistance genes (dfrA1, dfrA5, dfrA7, dfrA12, dfrA17, sul1, sul2, sul3 and class 1 and 2 integron-associated dfrA gene cassettes was tested. Resistance to TMP was very high during the administration of the antimicrobial (from 97 to 100% and amounted to 86% and 69% in the post-exposure period; MIC > 32 mg/L. The isolates from all groups of pigs were resistant to sulfamethoxazole, with MIC > 1028 mg/L. The dfrA1 and sul1 genes (as part of integrons dominated in E. coli from piglets, but the dfrA12 and sul1 genes were prevalent in E. coli from sows. Coexistence of the different dfrA genes was detected in 71 isolates from all groups of swine. Transcription analysis revealed that most of these genes were not transcribed, particularly gene cassettes of class 1 integrons. The research revealed a high level of resistance associated with the metaphylactic treatment, persistence and circulation of resistance in bacterial populations. Diverse genetic background with multiple and not transcribed resistance genes was observed.

    Fluoroquinolone (FQ) and fluconazole prophylaxis is recommended for patients undergoing allogeneic hematopoietic cell transplantation (alloHCT). However, due to an uncertain scientific basis and the increasing emergence of resistant germs, this policy should be questioned. Therefore, FQ and fluconazole prophylaxis was omitted in alloHCT at our center. In this retrospective analysis, all consecutive patients (n = 63) who underwent first alloHCT at our institution from September 2010 to September 2013 were included. Patients neither received FQ nor fluconazole prophylaxis. Day 100 mortality, incidence of febrile neutropenia, bacterial infections, and invasive fungal diseases (IFD) were assessed. Sixteen patients who started conditioning under antimicrobial treatment/prophylaxis due to pre-existing neutropenia (3/16), IFD (12/16), or aortic valve replacement (1/16) were excluded from the analysis. Finally, 47 patients were transplanted without prophylaxis as intended. Day 100 mortality was 9 %. Febrile neutropenia occurred in 62 % (29/47); 17/47 patients (36 %) experienced a blood stream infection (BSI) with detection of Gram-positive bacteria in 14 patients, Gram-negative bacteria in five patients, and candida in one patient, respectively. Coagulase-negative staphylococci were the most frequently isolated Gram-positive bacteria; 12/21 isolated Gram-positive and 3/6 Gram-negative bacteria were FQ resistant. In 21 % (10/47) of the patients, IFD (1x proven, 1x probable, and 8x possible) were diagnosed. To conclude, all three criteria, day 100 mortality, the incidence of IFD, and BSI, are in the range of published data for patients transplanted with FQ and fluconazole prophylaxis. These data demonstrate that alloHCT is feasible without FQ and fluconazole prophylaxis.

    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.

  18. Is Antibiotic Prophylaxis Necessary in Patients Undergoing Ureterolithotripsy?

    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.

  19. Antibiotic prophylaxis for dentoalveolar surgery: is it indicated?

    Usually dentists in Australia give patients oral antibiotics after dentoalveolar surgery as a prophylaxis against wound infection. When this practice is compared to the principle of antibiotic prophylaxis in major surgery it is found to be at variance in a number of ways. In major surgery, the risk of infection should be high, and the consequences of infection severe or catastrophic, before antibiotic prophylaxis is ordered. If it is provided then a high dose of an appropriate spectrum antibiotic must be present in the blood prior to the first incision. Other factors which need to be considered are the degree of tissue trauma, the extent of host compromise, other medical comorbidities and length of hospitalization. Standardized protocols of administration have been determined and evaluated for most major surgical procedures. Dentoalveolar surgery is undoubtedly a skilled and technically challenging procedure. However, in contrast to major surgical procedures, it has a less than five per cent infection rate and rarely has severe adverse consequences. Dentoalveolar surgery should be of short duration with minimal tissue damage and performed in the dental chair under local anaesthesia. Controlled studies for both mandibular third molar surgery and placement of dental implants show little or no evidence of benefit from antibiotic prophylaxis and there is an adverse risk from the antibiotic. This review concludes that there is no case for antibiotic prophylaxis for most dentoalveolar surgery in fit patients. In the few cases where it can be considered, a single high preoperative dose should be given.

    Topical antibiotics are not indicated for routine postoperative care in clean dermatologic procedures, but may be widely used. We sought to describe topical antibiotic use in clean dermatologic surgical procedures in the United States. The 1993 to 2007 National Ambulatory Medical Care Survey database was queried for visits in which clean dermatologic surgery was performed. We analyzed provider specialty, use of topical antibiotics, and associated diagnoses. Use of topical antibiotic over time was analyzed by linear regression. An estimated 212 million clean dermatologic procedures were performed between 1993 and 2007; topical antibiotics were reported in approximately 10.6 million (5.0%) procedures. Dermatologists were responsible for 63.3% of dermatologic surgery procedures and reported use of topical antibiotic prophylaxis in 8.0 million (6.0%). Dermatologists were more likely to use topical antibiotic prophylaxis than nondermatologists (6.0% vs 3.5%). Use of topical antibiotic prophylaxis decreased over time. Data were limited to outpatient procedures. The assumption was made that when topical antibiotics were documented at procedure visits they were being used as prophylaxis. Topical antibiotics continue to be used as prophylaxis in clean dermatologic procedures, despite being ineffective for this purpose and posing a risk to patients. Although topical antibiotic use is decreasing, prophylactic use should be eliminated. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

  1. Reasonable application of antibiotic prophylaxis in maxillofacial trauma: Literature review

    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.

    Full Text Available Aim: To present our clinical experience about infective complications due to ultrasound guided transrectal prostate biopsy under ciprofloxacin plus third-generation cephalosporin (Ceftriaxone combination prophylaxis. Material and Method: The 1193 patients that used combination of ceftriaxone 1 g intramuscular 1 hour before biopsy and ciprofloxacin 500 mg twice a day for 5 days after biopsy were included to study. Before biopsy, urine analysis and urinary cultures were not performed routinely. Serious infective complications such as acute prostatitis and urosepsis, causing microorganisms were evaluated. Results: Serious infective complications occurred in (1.3% 16 patients. Fifteen of them had acute prostatitis and urine culture results were positive in 10/15 patients for Escherichia coli. The strains were uniformly resistant to ciprofloxacin. Only 1 patient had urosepsis and his blood and urine cultures demonstrated extended- spectrum %u03B2-lactamase-producing (ESBL Escherichia coli also resistant to ciprofloxacin. Antibiotic treatment-related side effects were not observed in any patient. Discussion: Although there is not a certain procedure, ciprofloxacin is the most common used antibiotic for transrectal prostate biopsy prophylaxis. On the other hand, the incidence of ciprofloxacin resistant Escherichia coli strain is increasing. Thus, new prophylaxis strategies have to be discussed. Ceftriaxone plus ciprofloxacin prophylaxis is safe and can be useable option for prophylaxis of prostate biopsy.

    Tetramethylenedisulfotetramine (TETS) is a potent convulsant poison for which there is currently no approved antidote. The convulsant action of TETS is thought to be mediated by inhibition of type A gamma-aminobutyric acid receptor (GABA{sub A}R) function. We, therefore, investigated the effects of post-exposure administration of diazepam, a GABA{sub A}R positive allosteric modulator, on seizure activity, death and neuroinflammation in adult male Swiss mice injected with a lethal dose of TETS (0.15 mg/kg, ip). Administration of a high dose of diazepam (5 mg/kg, ip) immediately following the second clonic seizure (approximately 20 min post-TETS injection) effectively prevented progression to tonic seizures and death. However, this treatment did not prevent persistent reactive astrogliosis and microglial activation, as determined by GFAP and Iba-1 immunoreactivity and microglial cell morphology. Inhibition of soluble epoxide hydrolase (sEH) has been shown to exert potent anti-inflammatory effects and to increase survival in mice intoxicated with other GABA{sub A}R antagonists. The sEH inhibitor TUPS (1 mg/kg, ip) administered immediately after the second clonic seizure did not protect TETS-intoxicated animals from tonic seizures or death. Combined administration of diazepam (5 mg/kg, ip) and TUPS (1 mg/kg, ip, starting 1 h after diazepam and repeated every 24 h) prevented TETS-induced lethality and influenced signs of neuroinflammation in some brain regions. Significantly decreased microglial activation and enhanced reactive astrogliosis were observed in the hippocampus, with no changes in the cortex. Combining an agent that targets specific anti-inflammatory mechanisms with a traditional antiseizure drug may enhance treatment outcome in TETS intoxication. - Highlights: • Acute TETS intoxication causes delayed and persistent neuroinflammation. • Diazepam given post-TETS prevents lethal tonic seizures but not neuroinflammation. • A soluble epoxide hydrolase

    Full Text Available DNA vaccination of transchromosomal bovines (TcBs with DNA vaccines expressing the codon-optimized (co glycoprotein (GP genes of Ebola virus (EBOV and Sudan virus (SUDV produce fully human polyclonal antibodies (pAbs that recognize both viruses and demonstrate robust neutralizing activity. Each TcB was vaccinated by intramuscular electroporation (IM-EP a total of four times and at each administration received 10 mg of the EBOV-GPco DNA vaccine and 10 mg of the SUDV-GPco DNA vaccine at two sites on the left and right sides, respectively. After two vaccinations, robust antibody responses (titers > 1000 were detected by ELISA against whole irradiated EBOV or SUDV and recombinant EBOV-GP or SUDV-GP (rGP antigens, with higher titers observed for the rGP antigens. Strong, virus neutralizing antibody responses (titers >1000 were detected after three vaccinations when measured by vesicular stomatitis virus-based pseudovirion neutralization assay (PsVNA. Maximal neutralizing antibody responses were identified by traditional plaque reduction neutralization tests (PRNT after four vaccinations. Neutralizing activity of human immunoglobulins (IgG purified from TcB plasma collected after three vaccinations and injected intraperitoneally (IP into mice at a 100 mg/kg dose was detected in the serum by PsVNA up to 14 days after administration. Passive transfer by IP injection of the purified IgG (100 mg/kg to groups of BALB/c mice one day after IP challenge with mouse adapted (ma EBOV resulted in 80% protection while all mice treated with non-specific pAbs succumbed. Similarly, interferon receptor 1 knockout (IFNAR(-/- mice receiving the purified IgG (100 mg/kg by IP injection one day after IP challenge with wild type SUDV resulted in 89% survival. These results are the first to demonstrate that filovirus GP DNA vaccines administered to TcBs by IM-EP can elicit neutralizing antibodies that provide post-exposure protection. Additionally, these data describe

    The application of cleaning and polishing agents to a patient's dentition is a routine part of many dental practices. This study measured the surface roughness and surface gloss of tooth enamel, composite resin, and dental porcelain restorative materials when exposed to a paste-free prophylaxis polishing cup as well as a conventional prophylaxis polishing paste. Samples of human tooth enamel, a composite resin restorative material, and dental porcelain were prepared by a series of polishing papers to produce a flat smooth surface. The baseline average surface roughness (Ra) was measured using a contact stylus profilometer, and the surface gloss was measured with a glossmeter. The test samples were subjected to a standardized polishing routine using a paste-free prophylaxis polishing cup and a fine- or coarse-particle prophylaxis paste. Post-treatment surface roughness and gloss measurements were compared using a paired t statistical test. The conventional prophylaxis pastes increased surface roughness and decreased the gloss of the composite resin and tooth enamel test groups. The paste-free cups did not significantly affect the surface roughness of the enamel or the restorative materials. Dental porcelain surface roughness essentially was not affected by the application of paste-free cups and the fine and coarse pastes.

    We investigated the efficacy of posaconazole prophylaxis in preventing invasive aspergillosis due to azole-resistant Aspergillus fumigatus isolates. Using a neutropenic murine model of pulmonary infection, posaconazole prophylaxis was evaluated using three isogenic clinical isolates, with posaconazole MICs of 0.063 mg/liter (wild type), 0.5 mg/liter (F219I mutation), and 16 mg/liter. A fourth isolate harboring TR34/L98H (MIC of 0.5 mg/liter) was also tested. Posaconazole prophylaxis was effective in A. fumigatus with posaconazole MICs of ≤0.5 mg/liter, where 100% survival was reached. However, breakthrough infection was observed in mice infected with the isolate for which the posaconazole MIC was >16 mg/liter.

    Full Text Available Poland is one of the countries with high cervical cancer morbidity and mortality. The main means to change this situation is to manage an active and modern programme of cervical cancer prophylaxis and diagnostics. To a large extent, the effectiveness of a cervical cancer prophylaxis programme is decided by the availability of modern diagnostic research. The conventional Papanicolaou test and modern LBC cytology techniques were discussed in the article, taking into consideration HPV diagnostics in the procedures for carefully selected cytological diagnosis, in the so called in-depth stage of preventive screening tests and the role of the p16 biomarker in predicting the development of a higher degree of epithelial-cell pathologies of the cervix. Colposcopy as a diagnostic method for the verification of cytological and virological abnormalities. The modern LEEP/LLETZ procedure used in diagnosis and treatment of cervical changes is used to realise the in-depth stage of cervical cancer prophylaxis programmes.

    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.

    Full Text Available 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.

    2014-04-01

    Pneumocystis jirovecii pneumonia (PCP) is increasingly reported in patients without HIV. Corticosteroids are a major risk factor, with up to 90% of patients receiving corticosteroid treatment prior to the development of PCP. In view of this, many specialties now prescribe PCP prophylaxis to patients receiving prolonged or high-dose glucocorticoid regimens. Neurologists frequently prescribe corticosteroids but may not be as aware of the risk for PCP. Here, we review the evidence for routine PCP prophylaxis among regular glucocorticoid users and ask what guidance there is on the subject for neurologists.

    Deep vein thrombosis (DVT) and pulmonary embolism (PTE) are known as venous thromboembolism (VTE). DVT occurs when a thrombus (a blood clot) forms in deep veins of the body, usually in the lower extremities. It can cause swelling or leg pain, but sometimes may occur with no symptoms. Awareness of DVT is the best way to prevent the VTE. Patients with trauma are at increased risk of DVT and subsequent PE because of coagulopathy in patients with multiple trauma, DVT prophylaxis is essential but the VTE prophylaxis strategy is controversial for the trauma patients. The risk factors for VTE includes pelvic and lower extremity fractures, and head injury.

    Isoimmunisation RhD has an important perinatal morbidity and mortality. Since prophylaxis was introduced in the sixties, the incidence of haemolytic disease of the newborn has decreased. When administred in due time and in the right dosage anti-D immunoglobulin can prevent sensibilization. Nevertheless new cases continue to occur, underlying the need for an urgent improvement of our conduct. The purpose of this review is to provide an overview of the pathology of RhD isoimmunization and of aspects involved in its prophylaxis.

Despite extended prevalence of this type of headache there is lack of evidence about best drug treatment for migraine. So we aimed to compare the therapeutic effects of these drugs on childhood migraine.Materials & MethodsIn the current study, a randomized clinical trial consisting of 78 patients according to 2004 International Headache Association criteria were randomly assigned to two groups that matched by age and sex. One of these two groups was treated with Topiramate, while the other was given Propranolol. After one and four months, the efficiency of these treatments was measured in terms of frequency, severity and duration of migraine attacks.ResultsResults obtained from the data collected showed that of these 78 studied patients, 38 patients received Topiramate treatment (group A and the rest (40 patients; group B was treated with Propranolol. The average age of group A was 8.5± 2.9 years and that of group B was 8.3 ± 2.8 years. No significant difference was observed between these two groups in terms of reduction in frequency, severity and duration of migraine attacks.ConclusionResults showed that both treatments had the same efficiency in healing migraine headaches and there was no significant difference between their treating results. However, further studies are needed to examine medical effects of these two medicines. ReferencesAbu-Arefeh  I,  Russell  G.  Prevalence  of  headache  and migraine in schoolchildren.

    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.

However, existing prophylaxis guidelines are rarely followed. Objective: The aim of the study was to present and discuss implementation strategies and the results of a VTE prophylaxis program for medical and surgical patients admitted to a large general hospital. Patients and methods: This prospective observational study was conducted to describe the strategy used to implement a VTE prophylaxis program in hospitalized medical and surgical patients and to analyze the results in terms of the risk assessment rate within the first 24 hours after admission, adequacy of the prophylaxis prescription, and prevalence of  VTE in the discharge records before and after program implementation. We used the Mantel–Haenszel chi-square test for the linear trend of the data analysis and set the significance level to P<0.05. Results: With the support of an institutional VTE prophylaxis committee, a multiple-strategy approach was used in the implementation of the protocol, which included continuing education, complete data recording using computerized systems, and continuous auditing of and feedback to the medical staff and multidisciplinary teams. Approximately 90% of patients were evaluated within the first 24 hours after admission, and no significant difference in this percentage was observed among the years analyzed. A progressive increase in adherence to protocol recommendations, from 63.8% in 2010 to 75.0% in 2014 (P<0.001, was noted. The prevalence of symptomatic VTE in the discharge records of patients decreased from 2.03% in 2009 to 1.69% in 2014 (P=0.033. Conclusion: The implementation of a VTE prophylaxis program

Approximately 110 trials met our inclusion criteria and were included in the current review.Results: The most effective pharmacological treatment for migraine prophylaxis is propranolol and anticonvulsants such as topiramate, valproic acid, and amitriptyline. Nonmedical treatments such as acupuncture, biofeedback, and melatonin have also been proposed. Peripheral neurostimulation has been suggested for the treatment of chronic daily headache that does not respond to prophylaxis and for the treatment of drug-resistant primary headache. The majority of the pharmacological agents available today have limited efficacy and may cause adverse effects incompatible with long-term use.Limitations: The review was limited by the highly variable and often insufficient reporting of the complex outcome data and by the fact that migraine prophylaxis trials

    The main aim was to assess the effects of a spa treatment on the resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission. A cost-effectiveness analysis (CEA) was also performed. A multicentre randomised controlled trial was carried out between 2008 and 2010 in the University Hospital of Auvergne and two private hospitals in Clermont-Ferrand, France. Eligible patients were women in complete breast cancer remission without contraindication for physical activities or cognitive disorders and a body mass index between 18.5 and 40 kg/m(2). The intervention group underwent spa treatment combined with consultation with dietician whereas the control underwent consultations with the dietician only. Of the 181 patients randomised, 92 and 89 were included in the intervention and the control groups, respectively. The CEA involved 90 patients, 42 from the intervention group and 48 from the control group. The main results showed a higher rate of resumption of occupational activities in the intervention group (p = 0.0025) and a positive effect of the intervention on the women's ability to perform occupational activities 12 months after the beginning of the study (p = 0.0014), and on their ability to perform family activities (p = 0.033). The stay in a thermal centre was cost-effective at 12 months. Spa treatment is a cost-effective strategy to improve resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission. Copyright © 2014 Elsevier Ltd.

    Full Text Available Context There is a need to find if patients with poorly controlled diabetes, immunosuppression, or autoimmune disease require different perioperative antibiotic prophylaxis. There is also a need to determine if antibiotic prophylaxis should be different for primary cases, revision cases, hip arthroplasty and knee arthroplasty. The best antibiotic prophylaxis to choose in patients with colonization by carbapenem resistant enterobacteriaceae or multi-drug resistant (MDR-Acinetobacter spp needs to be determined. Evidence Acquisition Delegates in workgroup 3 of the consensus meeting on PJI reviewed English literature for relevant articles. 30 of 221 articles were relevant to the 4 following questions regarding perioperative antibiotic prophylaxis to prevent PJI. Results There is no need to use different antibiotic prophylaxis for patients with poorly controlled diabetes, immunosuppression, or autoimmune disease than routine antibiotic prophylaxis. Perioperative antibiotic prophylaxis should be the same for primary and uninfected revision arthroplasty. Perioperative antibiotic prophylaxis should be the same for hips and knees arthroplasties. There is insufficient data to recommend expanded antibiotic prophylaxis in patients known to be colonized or recently infected with multi-drug resistant pathogens. Conclusions Based on evidences in the literature and consensus of expert delegates from consensus meeting recommendations for type of antibiotic prophylaxis in patients with poorly controlled diabetes, immunosuppression, or autoimmune disease, primary and uninfected revision arthroplasty, hip or knee arthroplasties and patients known to be colonized or recently infected with multi-drug resistant pathogens were provided.

    2006-12-01

    Reduced-intensity stem cell transplantation (RIST) has been developed to be a novel curative option for advanced hematologic diseases. Its minimal toxicity allows for transplantation in patients with advanced age or with organ dysfunction. Young patients without comorbidity can undergo RIST as outpatients. However, fungal infection remains an important complication in RIST. Given the poor prognosis of fungal infection, prophylaxis is critical in its management. The prophylactic strategy is recently changing with the development of RIST. Hospital equipment is important for fungal prophylaxis; however, the median day for the development of fungal infection is day 100, when most RIST patients are followed as outpatients. The focus of fungal management after RIST needs to shift from in-hospital equipment to oral antifungals. Various antifungals have recently been developed and introduced for clinical use. A major change in antifungal management will probably occur within several years.

    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.

Very importantly, persistent HPV infection of certain types is a leading cause of carcinoma of uterine cervix, penis, vulva; vagina, anal canal and fauces (including tongue base and tonsils). HPV infection prophylaxis is the best means to control HPV-conditioned diseases, and vaccination, as had been demonstrated, --the most effective method of its prophylaxis. In this paper principle characteristics and clinical manifestations of papillomavirus infection, as well as effectiveness of vaccination against HPV are examined.

    Full Text Available The surgical wound infection is the biggest cause of infectious morbility in surgical patients. It is an important cause of morbility that causes lincreased hospital demurrages, increased cost of medical attention and serious inconveniences to the patients and their familiies. 25% of all nosocomial infections are surgical wound infection. One of the big advances of the surgery in the last three decades is an introduction of antibiotic prophylaxis in the surgical practice. Is considered that it has saved more lives than any other novel procedure in surgery in the last 20 years. We presented the Good Clinical Practices Guideline for Antibiotic prophylaxis in abdominal surgery, approved by consensus in the 1st National Good Clinical Practices Workshop in Pediatric Surgery (Cienfuegos, Cuba, March 7 – 9, 2002.

    Posaconazole, a fluorinated triazole antifungal drug, is approved by the U.S. Food and Drug Administration (FDA) for (1) prophylaxis against Aspergillus and Candida infections in immunocompromised patients at high risk for these infections and (2) oropharyngeal candidiasis (OPC), including cases refractory to fluconazole and/or itraconazole. The European Medicines Agency (EMA) has approved posaconazole for (1) treatment of aspergillosis, fusariosis, chromoblastomycosis, and coccidioidomycosis in patients who are refractory to or intolerant of other azoles or amphotericin B; (2) first-line therapy for OPC for severe disease or in those unlikely to respond to topical therapy; and (3) prophylaxis of invasive fungal infections in high-risk hematologic patients and stem cell transplant recipients. In addition to approved indications, posaconazole has been used with success as salvage therapy for invasive mold infections and endemic mycoses in patients who are refractory to or intolerant of other antifungal agents, and as prophylaxis or salvage therapy in children, for whom indications are more limited owing to a paucity of data. Posaconazole has potent in vitro activity against a broad range of fungi and molds, including Aspergillus, Candida, Cryptococcus, filamentous fungi, and endemic mycoses including coccidioidomycosis, histoplasmosis, and blastomycosis. Importantly, posaconazole is much more active than other azoles against many Mucorales species and the combination of posaconazole with other antifungal agents may be synergistic. Hence, posaconazole is a potential candidate as a single or combination agent for difficult-to-treat fungal infections. Posaconazole has an excellent safety profile; to date, serious side effects are rare, even with prolonged use. However, newer posaconazole formulations achieve higher blood levels and it remains to be seen whether this may lead to an increase in the rate of adverse effects. Currently, posaconazole is used predominantly

    Malnutrition by definition may be an abnormality in either under- or overnutrition. Nutrition reconciliation means that all patients have their nutritional status reconciled on admission to and discharge from the hospital. Nutrition reconciliation is defined as the process of maximizing health by helping align an individual’s current diet to the diet prescribed for him or her by the health care team. Nutrition prophylaxis is a proactive intervention to prevent a medical complication.

    Full Text Available Maria Adriana Cataldo, Nicola PetrosilloSecond Infectious Diseases Division, National Institute for Infectious Diseases, “Lazzaro Spallanzani”, Rome, ItalyAbstract: Fungi are a frequent cause of nosocomial infections, with an incidence that has increased significantly in recent years, especially among critically ill patients who require intensive care unit (ICU admission. Among ICU patients, postsurgical patients have a higher risk of Candida infections in the bloodstream. In consideration of the high incidence of fungal infections in these patients, their strong impact on mortality rate, and of the difficulties in Candida diagnosis, some experts suggest the use of antifungal prophylaxis in critically ill surgical patients. A clinical benefit from this strategy has been demonstrated, but the economic impact of the use of antifungal prophylaxis in surgical patients has not been systematically evaluated, and its cost–benefit ratio has not been defined. Whereas the costs associated with treating fungal infections are very high, the cost of antifungal drugs varies from affordable (ie, the older azoles to expensive (ie, echinocandins, polyenes, and the newer azoles. Adverse drug-related effects and the possibly increased incidence of fluconazole resistance and of isolates other than Candida albicans must also be taken into account. From the published studies of antifungal prophylaxis in surgical patients, a likely economic benefit of this strategy could be inferred, but its usefulness and cost–benefits should be evaluated in light of local data, because the available evidence does not permit general recommendations.Keywords: antifungal prophylaxis, cost-effectiveness, economics, surgery, fungal infection

    Long-term acyclovir (ACV) prophylaxis, recommended to prevent recurrent herpes simplex virus type 1 (HSV-1) ocular disorders, may pose a risk for ACV-refractory disease due to ACV resistance. We determined the effect of ACV prophylaxis on the prevalence of corneal ACV-resistant (ACV(R)) HSV-1 and clinical consequences thereof in patients with recurrent HSV-1 keratitis (rHK). Frequencies of ACV(R) viruses were determined in 169 corneal HSV-1 isolates from 78 rHK patients with a history of stromal disease. The isolates' ACV susceptibility profiles were correlated with clinical parameters to identify risk factors predisposing to ACV(R) rHK. Corneal HSV-1 isolates with >28% ACV(R) viruses were defined as ACV(R) isolates. Forty-four isolates (26%) were ACV-resistant. Multivariate analyses identified long-term ACV prophylaxis (≥12 months) (odds ratio [OR] 3.42; 95% confidence interval [CI], 1.32-8.87) and recurrence duration of ≥45 days (OR 2.23; 95% CI, 1.02-4.87), indicative of ACV-refractory disease, as independent risk factors for ACV(R) isolates. Moreover, a corneal ACV(R) isolate was a risk factor for ACV-refractory disease (OR 2.28; 95% CI, 1.06-4.89). The data suggest that long-term ACV prophylaxis predisposes to ACV-refractory disease due to the emergence of corneal ACV(R) HSV-1. ACV-susceptibility testing is warranted during follow-up of rHK patients.

    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.

    2014-01-01

    Efficacy of clinical guidelines to improve patient care is highly dependent on the ability of hospital teams to interpret and implement advised standards of care. Trimester and bi-annual rotation changes often see transference and loss of acquired experience and knowledge from wards with ensuing shortfalls in patient safety and care quality. Such shortfalls were noticed in the ability of our unit to adhere to national venous thromboembolism (VTE) prophylaxis measures. A prospective quality improvement audit was embarked upon to address this. An initial audit of VTE prophylaxis in 112 patients demonstrated just 71% compliance with suggested measures. Errors were predominantly medical in origin and secondary to poor understanding, interpretation, and knowledge of VTE guidelines. Errors were also noted in nursing and patient compliance to measures. Repeated re-auditing demonstrated increased error (following initial improvement post audit) after periods of medical staff rotation. Through education of junior medical and nursing staff, and of patients, the unit was able to achieve 100% compliance. Rota changes often induce conflict of interest between maintaining adequate services and high levels of patient care or providing suitable and informed induction programmes for new medical staff. Emphasised education of VTE prophylaxis guidelines has now become part of induction of junior medical staff, whilst ward based measures ensure daily compliance. The success of the audit strategy has led to its use throughout other surgical units within the hospital.

    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

    The use of antibiotic prophylaxis to prevent urinary tract infection and bacteremia (sepsis) following endoscopic urologic procedures is a controversial topic. Evidence in the literature revealed that urological instrumentation is associated with increased incidence of urinary tract infection and bacteremia. The aim of this review is to evaluate the effectiveness of antibiotic prophylaxis in reducing the risk of urinary tract infection in patients who had transurethral urological surgeries. We have selected all RCTs of adult population who underwent all different types of transurethral urological surgery, including cystoscopy, transurethral resection of prostate and transurethral resection of bladder tumor, and received prophylactic antibiotics or placebo/no treatment. At first, more than 3000 references were identified and reviewed; of which 42 studies with a total of 7496 patients were included in the final analysis. All those trials were analyzing antibiotic prophylaxis versus placebo/no treatment, and they were significantly favoring antibiotic use in reducing all outcomes, including bacteriuria (RR 0.36, 95% CI 0.29 to 0.46, P urinary tract infections and its sequels following transurethral urological surgeries in patients with preoperative sterile urine.

  4. Antibiotic prophylaxis in infective endocarditis: Use or abuse?

    2012-01-01

    Full Text Available Introduction: The American Heart Association (AHA recommendations for antimicrobial prophylaxis for infective endocarditis (IE are controversial. According to the new guidelines released by the AHA now, the only patients to receive antibiotics will be those at highest risk, i.e. those with a prosthetic heart valve, a history of endocarditis, certain forms of congenital heart disease or valvulopathy after heart transplantation, and only before certain dental procedures. Unfortunately, these guidelines are still based largely on expert opinion, with very little hard evidence to show that antibiotic therapy actually prevents IE. The Hypothesis: The reported incidence of bacteremia during dental intervention ranges from 10% to 100% and, with daily brushing and flossing, from 20% to 68%. Because bacteremia also occurs during brushing and flossing of teeth, why give prophylaxis just for dental procedures? Moreover, the risks of causing adverse or anaphylactic reactions from antibiotics as well as contributing to the nationwide antibiotic resistance problem are issues not to be taken lightly. Evaluation of the Hypothesis: The hypothesis discusses the AHA recommendations for antimicrobial prophylaxis for IE, indicating some inherent limitations associated with it, and stresses upon the fact that these recommendation should also be updated, if not completely changed, to cope up with the advancements in the proper treatment plan.

    Background The single most important risk factor for postpartum maternal infection is cesarean section. Routine prophylaxis with antibiotics may reduce this risk and should be assessed in terms of benefits and harms. Objectives To assess the effects of prophylactic antibiotics compared with no prophylactic antibiotics on infectious complications in women undergoing cesarean section. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (May 2009). Selection criteria Randomized controlled trials (RCTs) and quasi-RCTs comparing the effects of prophylactic antibiotics versus no treatment in women undergoing cesarean section. Data collection and analysis Two authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. Main results We identified 86 studies involving over 13,000 women. Prophylactic antibiotics in women undergoing cesarean section substantially reduced the incidence of febrile morbidity (average risk ratio (RR) 0.45; 95% confidence interval (CI) 0.39 to 0.51, 50 studies, 8141 women), wound infection (average RR 0.39; 95% CI 0.32 to 0.48, 77 studies, 11,961 women), endometritis (RR 0.38; 95% CI 0.34 to 0.42, 79 studies, 12,142 women) and serious maternal infectious complications (RR 0.31; 95% CI 0.19 to 0.48, 31 studies, 5047 women). No conclusions can be made about other maternal adverse effects from these studies (RR 2.43; 95% CI 1.00 to 5.90, 13 studies, 2131 women). None of the 86 studies reported infant adverse outcomes and in particular there was no assessment of infant oral thrush. There was no systematic collection of data on bacterial drug resistance. The findings were similar whether the cesarean section was elective or non elective, and whether the antibiotic was given before or after umbilical cord clamping. Overall, the methodological quality of the trials was unclear and in only a few studies was it obvious that potential other sources of bias had been

    Recipients of liver transplantation (LT) are at increased risk for symptomatic coccidioidomycosis, primarily because of chronic immunosuppression and impaired cellular immunity. Unfortunately, no consensus exists regarding optimal posttransplant prophylaxis. In a prior study at our institution, we observed both de novo and recurrent coccidioidomycosis despite targeted antifungal prophylaxis. In response, in February 2011, we instituted a universal prophylaxis program consisting of fluconazole (200 mg daily) for the first posttransplant year. In the current study, we retrospectively reviewed the medical records of all patients who underwent LT between the initiation of universal prophylaxis and July 11, 2013. Patients receiving a second transplant or dual-organ transplant and those who died or did not have follow-up in the 12-month post-LT period were excluded. Data from the universal prophylaxis cohort were compared with previously published data from the targeted prophylaxis era. Of the 160 patients undergoing LT during the study period, 143 met criteria for data analysis. When compared with the 349 patients in the targeted prophylaxis cohort, patients in the universal prophylaxis group were older and had higher rates of pre-LT coccidioidomycosis, asymptomatic coccidioidal seropositivity, posttransplant diabetes mellitus, and renal insufficiency. Fluconazole-related toxicity occurred in 13 of the universal prophylaxis patients, 7 of whom were required to discontinue use of the medication. Coccidioidomycosis developed in 10 of the 391 patients (2.6%) in the targeted prophylaxis cohort and in none of the patients in the universal prophylaxis group (P = 0.04). These data strongly support the use of a 1-year antifungal prophylaxis regimen for LT recipients in endemic regions. © 2015 American Association for the Study of Liver Diseases.

    Posaconazole is a new oral triazole with broad-spectrum antifungal activity. Posaconazole has also shown a significant advantage of preventing invasive fungal infection compared to fluconazole or itraconazole in patients with prolonged neutropenia. Indeed, posaconazole has been commonly used for antifungal prophylaxis in patients undergoing remission induction chemotherapy for acute myelogenous leukemia or myelodysplastic syndrome. We experienced a case of fatal mucormycosis despite posaconazole prophylaxis. To our knowledge, this is the first reported case of fatal breakthrough mucormycosis in a patient receiving posaconazole prophylaxis during remission induction chemotherapy in Korea. This case demonstrated that breakthrough fungal infection can occurs in patients receiving posaconazole prophylaxis because of its limited activity against some mucorales.

    2011-01-01

    Venous thromboembolism (VTE) is the commonest cause of preventable death in hospitalized patients.Elderly patients have higher risk of VTE because of the high prevalence of predisposing comorbidities and acute illnesses.Clinical diagnosis of VTE in the elderly patient is particularly difficult and,as such,adequate VTE prophylaxis is of pivotal importance in reducing the mortality and morbidities of VTE.Omission of VTE prophylaxis is,however,very common despite continuous education.A simple way to overcome this problem is to implement universal VTE prophylaxis for all hospitalized elderly patients instead of selective prophylaxis for some patients only according to individual's risk of VTE.Although pharmacological VTE prophylaxis is effective for most patients,a high prevalence of renal impairment and drug interactions in the hospitalized elderly patients suggests that a multimodality approach may be more appropriate.Mechanical VTE prophylaxis,including calf and thigh compression devices and/or an inferior vena cava filter,are often underutilized in hospitalized elderly patients who are at high-risk of bleeding and VTE.Because pneumatic compression devices and thigh length stockings are virtually risk free,mechanical VTE prophylaxis may allow early or immediate implementation of VTE prophylaxis for all hospitalized elderly patients,regardless of their bleeding and VTE risk.Although the cost-effectiveness of this Multimodality Universal STat ('MUST') VTE prophylaxis approach for hospitalized elderly patients remains uncertain,this strategy appears to offer some advantages over the traditional `selective and single-modal' VTE prophylaxis approach,which often becomes `hit or miss' or not implemented promptly in many hospitalized elderly patients.A large clustered randomized controlled trial is,however,needed to assess whether early,multimodality,universal VTE prophylaxis can improve important clinical outcomes of hospitalized elderly patients.

    The aim of this study was to investigate the association of different dental prophylactic modalities and osteoradionecrosis (ORN) and determine the risk of ORN under different timing periods of scaling, with the use chlorhexidine mouth rinse after surgery and with different strategies of fluoride gel application in head and neck cancer (HNC) participants. A cohort of 18,231 HNC participants, including 941 ORN patients and 17,290 matched control cases, were enrolled from a Longitudinal Health Insurance Database for Catastrophic Illness Patients (LHID-CIP) in Taiwan. Based on different dental prophylactic modalities before radiotherapy, including chlorhexidine mouth rinse, scaling, and fluoride gel, all HNC subjects were stratified into different groups. The Cox proportional hazard regression was used to compare ORN incidences under different dental prophylactic modalities. The results revealed that scaling and chlorhexidine mouth rinse were significantly related to ORN risk ( P = 0.004 and P risk by 2.43-fold among oral cancer patients, regardless of whether they had received major oral surgery or not. Oral cancer patients receiving scaling within 2 wk before radiotherapy increased their incidence of ORN by 1.28-fold compared with patients who had not undergone scaling within 6 mo. There is no significance of fluoride application for dental prophylaxis in increasing ORN occurrence. In conclusion, dental prophylaxis before radiotherapy is strongly correlated to ORN in HNC patients. Chlorhexidine exposure and dental scaling within 2 wk before radiotherapy is significantly related to ORN risk, especially in oral cancer patients. The use of 1.1% NaF topical application did not significantly increase the risk of ORN in HNC patients. An optimal dental prophylaxis protocol to reduce ORN should concern cancer location, cautious prescription of chlorhexidine mouth rinse, and proper timing of scaling.

    Purpose Published cohorts of children with vesicoureteral reflux placed on antibiotic prophylaxis differ in baseline characteristics and methodology. These data have been combined in meta-analyses to derive treatment recommendations. We analyzed these cohorts in an attempt to understand the disparate outcomes reported. Materials and Methods Eighteen studies were identified from 1987 to 2013. These either retrospectively or prospectively evaluated children with VUR who were on long-term antibiotic prophylaxis. The presenting demographic data, criteria and methods of evaluation were tabulated. Outcomes were compared—specifically recurrent urinary infection and renal scarring. Results Significant differences in baseline characteristics and methodology were identified: gender, circumcision status, grade of reflux, evaluation of bowel and bladder dysfunction (BBD), methodology of urine collection, definition of urinary infection (UTI), measurement of compliance, means of identifying renal scarring. Cohorts with larger numbers of uncircumcised boys had more breakthrough UTI’s. Both infection and renal scarring rates were higher in series with higher grades of reflux. Bagged urine specimens were allowed in 6 series, rendering the data suspect. Children with BBD were excluded from 3 cohorts; only in 1 was BBD correlated with outcome. Compliance was monitored in only 6 studies. Conclusions Sub-populations as well as methodologies vary significantly in published series of children with VUR on anti-biotic prophylaxis. It is inappropriate to combine outcome data from these series in a meta-analysis, since this serves to blur distinctions between these sub-populations. Broad recommendations or guidelines based upon meta-analyses should be viewed with caution. PMID:22910235

    Venous thromboembolism (VTE) is a major cause of morbidity and mortality and is associated with substantial healthcare costs. Identification of patients at risk of developing VTE enables appropriate thromboprophylaxis to be implemented. Although no predisposing risk factors can be identified in many patients in whom VTE develops, most have at least one underlying risk factor which can be categorized according to whether it confers low, moderate, or high risk. Clinical trials have demonstrated the effectiveness of thromboprophylaxis, both non-pharmacological and pharmacological, in a host of medical settings and there is sufficient evidence to support routine prophylaxis in many groups of patients. The implementation of decision making tools based on risk factor assessment improves the prescription of appropriate VTE prophylaxis. Nonetheless, thromboprophylaxis is often inadequate, with haphazard risk assessment and application of guidelines, leading to easily preventable instances of VTE. The most commonly used agents for pharmacological thromboprophylaxis of VTE are low dose unfractionated heparin; a low molecular weight heparin such as dalteparin, enoxaparin or tinzaparin; fondaparinux; warfarin; or aspirin. However, these have a number of drawbacks, principally the need for parenteral administration (with heparins) and frequent coagulation monitoring (with warfarin). The optimal anticoagulant would be orally administered, with a wide therapeutic window, rapid onset of action, predictable pharmacodynamics and pharmacokinetics, minimal interactions with food and other drugs, an ability to inhibit free and clot-bound coagulation factors, low, non-specific binding, and no requirement for routine coagulation monitoring or dose adjustment. A number of novel, single-target oral anticoagulants have been developed that appear to fulfill many of these requirements. This narrative review discusses the use of guidelines and risk assessment tools to identify patients at risk

    Recurrent urinary tract infections (UTIs) are observed in 30-50% of children after the first UTI. Of these, approximately 90% occur within 3 months of the initial episode. The basic aim of antibiotic prophylaxis in children with malformative uropathy and/or recurrent UTIs, is to reduce the frequency of UTIs. The bacteria most frequently responsible for UTI are gram-negative organisms, with Escherichia coli accounting for 80% of urinary tract pathogens. In children with recurrent UTIs and in those treated with antibiotic prophylaxis there is a greater incidence of UTI due to Proteus spp., Klebsiella spp. and Enterobacter spp., whereas Pseudomonas spp., Serratia spp. and Candida spp. are more frequent in children with urogenital abnormalities and/or undergoing invasive instrumental investigations. Several factors are involved in the pathogenesis of UTI, the main ones being circumcision, periurethral flora, micturition disorders, bowel disorders, local factors and hygienic measures. Several factors facilitate UTI relapse: malformative uropathies, particularly of the obstructive type; vesico-ureteric reflux (VUR); previous repeated episodes of cystitis and/or pyelonephritis (3 or more episodes a year), even in the absence of urinary tract abnormalities; a frequently catheterized neurogenic bladder; kidney transplant. The precise mechanism of action of low-dose antibiotics is not yet fully known. The characteristics of the ideal prophylactic agent are presented in this review, as well as indications, dosages, side effects, clinical data of all molecules. While inappropriate use of antibiotic prophylaxis encourages the emergence of microbial resistance, its proper use may be of great value in clinical practice, by reducing the frequency and clinical expression of UTIs and, in some cases such as VUR, significantly helping to resolve the underlying pathology.

    The aim of the study was to estimate the efficacy of various variants of antibiotic prophylaxis of infectious complications in female patients after histeroscopy. 109 patients were examined. The patients were hospitalized for planned historoscopy. 55 of them were treated prophylactically to prevent infectious complications with a broad spectrum antibiotic administered intravenously 30 min prior to the operation. A course antimicrobial therapy during the postoperative period was applied to 54 females. The results of the trial showed that single administration of an antimicrobial provided high level prevention of infectious complications, whereas the use of course antimicrobial therapy during the postoperative period was of no advantage by the efficacy.

    Introduction HIV continues to be a major health concern with approximately 2.1 million new infections occurring worldwide in 2015. In Central America, Guatemala had the highest incident number of HIV infections (3,700) in 2015. Antiretroviral pre-exposure prophylaxis (PrEP) was recently recommended by the World Health Organization (WHO) as an efficacious intervention to prevent HIV transmission. PrEP implementation efforts are underway in Guatemala and success will require providers that are knowledgeable and willing to prescribe PrEP. We sought to explore current PrEP awareness and prescribing attitudes among Guatemalan physicians in order to inform future PrEP implementation efforts. Methods We conducted a cross-sectional survey of adult internal medicine physicians at the main teaching hospital in Guatemala City in March 2015. The survey included demographics, medical specialty, years of HIV patient care, PrEP awareness, willingness to prescribe PrEP, previous experience with post-exposure prophylaxis, and concerns about PrEP. The primary outcome was willingness to prescribe PrEP, which was assessed using a 5-point Likert scale for different at-risk population scenarios. Univariate and multivariate logistic regression was performed to identify predictors for willingness to prescribe PrEP. Results Eighty-seven physicians completed the survey; 66% were male, 64% were internal medicine residency trainees, and 10% were infectious disease (ID) specialists. Sixty-nine percent of physicians were PrEP aware, of which 9% had previously prescribed PrEP. Most (87%) of respondents were willing to prescribe PrEP to men who have sex with men (MSM), sex workers, injection drug users, or HIV-uninfected persons having known HIV-positive sexual partners. Concerns regarding PrEP included development of resistance (92%), risk compensation (90%), and cost (64%). Univariate logistic regression showed that younger age, being a resident trainee, and being a non-ID specialist were

    Full Text Available Prophylaxis has dramatically decreased the occurrence of cytomegalovirus (CMV infection after renal transplantation. Optimal regimens of treatment remain controversial, especially in pediatric recipients. The aim of this study was to evaluate the effectiveness of valganciclovir (VGC versus aciclovir/valaciclovir (ACV in a pediatric renal transplant population. Data from 101 renal transplantations were retrospectively analyzed. Except those with R-/Dstatus, all patients received prophylaxis either with ACV, n = 39 or VGC, n = 38. Incidences of positive CMV antigenemia and disease, as well as the delay in relation to the prophylaxis, were collected during at least 12 months after the end of treatment. Positive CMV antigenemia was reported in 34 patients (ACV: 16, VGC: 16, no prophylaxis: 2. CMV disease occurred in 15 patients (ACV: 5; VGC: 8 (ns. For the majority of patients under VGC, positive CMV antigenemia occurred within the year following the withdrawal of prophylaxis (VGC: 14; ACV: 5, P <0.05, whereas it occurred during prophylaxis in 11 patients under ACV versus two under VGC (P <0.05. The over-all incidence of positive CMV antigenemia was similar between ACV and VGC prophylaxis. However, VGC was more efficient to prevent early CMV infection while patients treated with ACV had less CMV infection or disease after the end of the prophylaxis.

    Patients undergoing allogeneic hematopoietic stem cell transplant are at a high risk for infection-related mortality in the immediate post-transplantation phase. Prophylaxis with a fluoroquinolone is now recommended to reduce this risk with the stipulation that surveillance for increased fluoroquinolone resistance Clostridium difficile associated diarrhea be conducted. We conducted a retrospective chart review of 48 patients who underwent an allogeneic hematopoietic stem cell transplant and received a fluoroquinolone for prophylaxis and 48 patients who underwent an allogeneic hematopoietic stem cell transplant who did not receive a fluoroquinolone for prophylaxis. All patients received the same standard antifungal, antiviral and anti-pneumocystis prophylaxis. Patients receiving fluoroquinolone prophylaxis had a lower incidence of febrile neutropenia than those not receiving prophylaxis, though the difference was not found to be statistically significant (83% vs. 67%, p = 0.098). Similar non-significant improvements in the number of positive cultures recovered during an episode of febrile neutropenia and antimicrobial days were noted. No significant increase in fluoroquinolone resistance, Clostridium difficile associated diarrhea, or in methicillin resistant Staphylococcus aureus infections were noted. Our single institution experience with fluoroquinolone prophylaxis for allogeneic hematopoietic stem cell transplant patients supports continuation of this practice. Expansion to autologous hematopoietic stem cell transplant patients may be appropriate based on guideline recommendations and our institution-specific experience with fluoroquinolone prophylaxis.

    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.

    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.

    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.

    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. PMID:27092529

    Full Text Available Abstract Radiotherapy for prophylaxis of heterotopic ossification (HO is commonly used in high risk patients following orthopedic surgery. While treatment is effective and can prevent morbidity associated with HO, with any dose of radiation there is a concern of a radiation induced malignancy. Here we a report a case of radiation induced osteosarcoma which developed 11 years after a single fraction of 700 cGy. We performed dosimetric analysis by superimposing the patient’s original treatment field on a CT scan performed after the diagnosis. The radiotherapy dose for this patient is lower than classically reported for radiation induced sarcomas. We identified greatest bony destruction that was thought to be the epicenter of the tumor, and this was specially contoured on the diagnostic CT scan. This volume appears to be located at the edge of the radiotherapy field. Fifty percent of the treated volume received 240 cGy, the mean dose was 333 cGy. There was a variation across the treatment volume, between 21.8 cGy and 717 cGy. While a rare complication, we stress the importance of informing regarding the risk of a radiation induced malignancy following HO prophylaxis.

    Full Text Available Migraine constitutes 16% of primary headaches affecting 10-20% of general population according to International Headache Society. Till now nonsteroidalanti-inflammatory drugs (NSAIDS, opioids and triptans are the drugs being used for acute attack of migraine. Substances with proven efficacy for prevention include β-blockers, calcium channel blockers, antiepileptic drugs and antidepressants. All the already available drugs have certain limitations. Either they are unable to produce complete relief or 30-40% patients are no responders or drugs produce adverse effects. This necessitates the search for more efficacious and well-tolerated drugs. A new class of drugs like angiotensin-converting enzyme inhibitors (ACE inhibitors and angiotensin II receptor antagonists have recently been studied for their off label use in prophylaxis of migraine. Studies, done so far, have shown results in favour of their clinical use because of the ability to reduce number of days with headache, number of days with migraine, hours with migraine, headache severity index, level of disability, improved Quality of life and decrease in consumption of specific or nonspecific analgesics. This article reviews the available evidence on the efficacy and safety of these drugs in prophylaxis of migraine and can give physician a direction to use these drugs for chronic migraineurs. Searches of pubmed, Cochrane database, Medscape, Google and clinicaltrial.org were made using terms like ACE inhibitors, angiotensin II receptor antagonists and migraine. Relevant journal articles were chosen to provide necessary information.

  18. The economics of hemodialysis catheter-related infection prophylaxis.

    2013-01-01

    Hemodialysis central venous catheter (CVC) use is associated with the highest morbidity, mortality, and cost of all types of hemodialysis vascular access. CVC-related infection drives much of the cost associated with CVC use. The magnitude of the cost associated with CVC-related infection varies depending on the type and severity of that infection; however, estimates of the total direct and indirect costs associated with hospitalizations due to hemodialysis CVC-related infections range from 17,000 USD to 32,000 USD per episode. Thus, it is critically important, to not only have effective strategies to limit CVC-related infection but also evaluate whether these strategies are an efficient use of resources. Prophylactic strategies can be considered economically efficient only if the value of its implementation and the corresponding drop in infection rate offer greater value than standard care. The optimal CVC-related infection prophylaxis strategy should work to limit infection risk with minimal risk, inconvenience, and discomfort to the patient, and at minimal cost. The aim of this review was to examine the clinical and economic impact of some commonly described interventions used for CVC infection prophylaxis.

    Full Text Available The evidence from the literature strongly support antifungal prophylaxis in high risk haematological patients, such as patients with AML during remission induction chemotherapy and alloHSCT patients. Current antifungal prophylaxis guidelines for high risk patients recommend azoles (fluconazole, posaconazole, voriconazole and echinocandins (micafungin with the strongest level of evidence. In terms of treatment, the choice between empiric therapy (or fever driven and pre-emptive therapy (or diagnostic driven is still debated. Not a single therapeutic strategy is appropriate in every patients, in particular empirical antifungal therapy may be recommended in patients at very high risk, while a pre-emptive approach may be advised for those at standard risk. In order to exploit the synergistic and/or additive effect of two antifungal drugs it’s possible to combine two agents that work with different mechanisms of action (e.g. echinocandins + azoles or polyenes. Once the treatment has been initiated we should consider the therapeutic drug monitoring (TDM of the drugs, especially when the pharmacokinetic variability is high and the dose-concentration effect relationships is not predictable (e.g. for itraconazole, voriconazole and posaconazole.

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.)

    To investigate behaviour in the use of drug prophylaxis against malaria and the risk factors for non-compliance, 507 European or North American travelers returning from endemic areas were studied retrospectively at Berlin in a 11-year period from 1980 to 1990. Compliance was significantly correlated with shorter travel duration: the group with good compliance stayed 37.2 +/- 38.5 days (mean +/- SD) in contrast to 69.8 +/- 93.5 days in the group of patients with no compliance (p = 0.00001). Older patients were significantly more compliant than patients aged 54 years vs. 175/476 at travel destination (Southern and East African regions; p = 0.0054), age ( or = 55 years, respectively; p = 0.0001), and reason of travel (package tours; p = 0.0001). CART analysis confirmed logistic regression analysis with respect to age and travel type, and revealed that patients using only one information source were significantly more compliant than those using two or more information sources. Travel agencies were nearly as well informed as Institutes of Tropical Medicine, but family doctors had a significant incidence of giving wrong advice. This study should enable medical personnel dealing with prophylactic advice against malaria to identify patients at high risk for non-compliance, and to educate them more carefully than other travellers regarding antimalarial drug prophylaxis.

    The new British Committee for Standards in Haematology (BCSH) guidelines for the use of anti-D immunoglobulin in pregnancy provide a welcome clarification of the use of anti-D in ectopic pregnancy and after red cell salvage during caesarean section, of dosing with different preparations and distinguishing non-immune and immune anti-D. The routine use of anti-D prophylaxis (RAADP) to prevent Rhesus (Rh) D alloimmunisation during the third trimester is well established and requires careful and well-audited local implementation to achieve the maximum public health benefit. In the UK, such scrutiny may be provided by the reporting of failed anti-D prophylaxis at women who have produced an immune anti-D that is detectable for the first time in the current pregnancy through the voluntary Serious Hazards of Transfusion reporting scheme (SHOT). Application of fetal RHD genotyping would avoid giving anti-D to RhD negative women carrying an RhD negative fetus. RAADP is directed by fetal RHD genotyping in some countries in Northern Europe led by the Netherlands and Denmark. The economic case for RAADP directed by fetal RHD genotyping needs to be carefully evaluated and in England is under consideration by National Institute for Health and Clinical Excellence (NICE). Possible future developments include the use of monoclonal anti-D preparations, now in advanced clinical trials, and also testing the hypothesis that directed RAADP from early in the second trimester may further reduce anti-D immunisation.

    The efficacy of isoniazid (INH) prophylaxis in renal allograft recipients who are on long-term immunosuppression in a region highly prevalent for tuberculosis (TB) was studied. INH (300 mg/d in patients weighing more than 35 kg and 5 mg/kg/d in patients with Pyridoxine 50 mg/d for 1 year was started in randomly assigned renal allograft recipients. Occurrence of clinical tuberculosis during the initial 2 years posttransplantation was observed in the risk group and patients at no risk. Risks were defined as acute rejection episodes and exposure to antirejection therapy, past history of TB completely or incompletely treated, radiological evidence of past tuberculosis, history of tuberculosis in close contacts. Among 480 patients registered in the study, INH prophylaxis was given to 219 randomly assigned renal allograft recipients. Results were compared among patients developing TB during the initial 2 years posttransplantation in both the groups. Risk factors were analyzed for comparison in both groups. No significant difference was observed in terms of past history of TB, TB in close contacts, episodes of acute rejection during the initial 3 months, and comorbidities such as cytomegalovirus infection, hepatitis C virus infection, and posttransplant diabetes. One patient from the INH group and 10 patients from the non-INH group developed TB during the initial 2 years posttransplantation (P < .0001). None of patients required discontinuation of INH. INH was observed to be safe and effective as a chemoprophylactic agent in renal allograft recipients.

    Background/Aims The aim of this study was to compare the efficacy and tolerability of topiramate and propranolol in preventing pediatric cyclic vomiting syndrome. Methods A retrospective medical-record review of patients who underwent prophylaxis after receiving a diagnosis of cyclic vomiting syndrome was performed. Patients who completed at least 12 months of treatment were included in the analysis. Responder rate, and adverse-event rates were also calculated from all patients. Response to treatment was assessed as the total number of vomiting attacks per year. Patients in whom the frequency of vomiting attack reduced greater or equal to 50% were defined as responders, and the remaining patients were classified as nonresponders. Results A total of 38 patients who were treated prophylactically with either topiramate (16 patients) or propranolol (22 patients) were identified. Fifty-nine percent of the patients in the propranolol group and 81% of the patients in the topiramate group reported freedom from attacks. A decrease of more than 50% in attacks per year occurred in 23% of patients in the propranolol group and 13% of patients in the topiramate group. The responder rates were 81% for propranolol group and 94% for topiramate group (P = 0.001). Despite minor adverse effects (drowsiness, nervousness, and dizziness) observed in a few patients, the adverse event rates were not significantly different between the 2 groups (P = 0.240). Conclusions The efficacy of topiramate was superior to propranolol for the prophylaxis of pediatric cyclic vomiting syndrome. PMID:27302967

    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.

    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.

    Migraine with aura is an established stroke risk factor, and excitatory mechanisms such as spreading depression (SD) are implicated in the pathogenesis of both migraine and stroke. Spontaneous SD waves originate within the peri-infarct tissue and exacerbate the metabolic mismatch during focal cerebral ischemia. Genetically enhanced SD susceptibility facilitates anoxic depolarizations and peri-infarct SDs and accelerates infarct growth, suggesting that susceptibility to SD is a critical determinant of vulnerability to ischemic injury. Because chronic treatment with migraine prophylactic drugs suppresses SD susceptibility, we tested whether migraine prophylaxis can also suppress ischemic depolarizations and improve stroke outcome. We measured the cortical susceptibility to SD and ischemic depolarizations, and determined tissue and neurological outcomes after middle cerebral artery occlusion in wild-type and familial hemiplegic migraine type 1 knock-in mice treated with vehicle, topiramate or lamotrigine daily for 7 weeks or as a single dose shortly before testing. Chronic treatment with topiramate or lamotrigine reduced the susceptibility to KCl-induced or electric stimulation-induced SDs as well as ischemic depolarizations in both wild-type and familial hemiplegic migraine type 1 mutant mice. Consequently, both tissue and neurological outcomes were improved. Notably, treatment with a single dose of either drug was ineffective. These data underscore the importance of hyperexcitability as a mechanism for increased stroke risk in migraineurs, and suggest that migraine prophylaxis may not only prevent migraine attacks but also protect migraineurs against ischemic injury. © 2014 American Heart Association, Inc.

    Rheumatic fever is caused by an abnormal immune reaction to group A streptococcal infection. Secondary prophylaxis with antibiotics is recommended for people after their initial episode of rheumatic fever to prevent recurrent group A streptococcal infections, recurrences of rheumatic fever and progression to rheumatic heart disease. This secondary prophylaxis must be maintained for at least a decade after the last episode of rheumatic fever. Benzathine penicillin G is the first line antibiotic for secondary prophylaxis, delivered intramuscularly every 2 to 4 weeks. However, adherence to recommended secondary prophylaxis regimens is a global challenge. This paper outlines a consultation with global experts in rheumatic heart disease on the characteristics of benzathine penicillin G formulations which could be changed to improve adherence with secondary prophylaxis. Characteristics included dose interval, pain, administration mechanism, cold chain independence and cost. A sample target product profile for reformulated benzathine penicillin G is presented.

    Immunizations belong to the most successful interventions in medicine. Like other drugs, vaccines undergo long periods of pre-clinical development, followed by careful clinical testing through study Phases I, II, and III before they receive licensure. A successful candidate vaccine will move on to be an investigational vaccine to undergo three phases of pre-licensure clinical trials in a stepwise fashion before it can be considered for approval, followed by an optional fourth phase of post-marketing assessment. The overall risk-benefit assessment of a candidate vaccine is very critical in making the licensure decision for regulatory authorities, supported by their scientific committees. It includes analyses of immunogenicity, efficacy, reactogenicity or tolerability, and safety of the vaccine. Public trust in vaccines is a key to the success of immunization programs worldwide. Maintaining this trust requires knowledge of the benefits and scientific understanding of real or perceived risks of immunizations. Under certain circumstances, pre- or post-exposure passive immunization can be achieved by administration of immunoglobulines. In terms of prevention of infectious diseases, disinfection can be applied to reduce the risk of transmission of pathogens from patient to patient, health-care workers to patients, patients to health-care workers, and objects or medical devices to patients.

    Background The incidence of venous thromboembolic events (VTE) after resection of thoracic malignancies can reach 15%, but prophylaxis guidelines are yet to be established. We aimed to survey Canadian practitioners regarding perioperative risk factors for VTE, impact of those factors on extended prophylaxis selection, type of preferred prophylaxis, and timing of initiation and duration of thromboprophylaxis. Methods A modified Delphi survey was undertaken over three rounds with thoracic surgeons, thoracic anesthesiologists and thrombosis experts across Canada. Participants were asked to rate each parameter on a ten-point scale. Agreement was determined a priori as an item reaching a coefficient of variation of ≤30% (0.3), with the item then discontinued from later rounds. Results In total, 72, 57 and 50 respondents participated in three consecutive rounds, respectively. Consensus was reached on previous VTE, age, cancer diagnosis, thrombophilia, poor mobilization, extended resections, and pre-operative chemotherapy as risk factors. Consensus on risk factors impacting extended prophylaxis decisions was achieved on cancer diagnosis, obesity, previous VTE and poor mobilization. With respect to perioperative prophylaxis, once daily low-molecular-weight heparin (LMWH) was the only parameter that demonstrated agreement as a common practice pattern. No agreement was achieved regarding the role of mechanical prophylaxis, unfractionated heparin (UFH) or timing of initiation of peri-operative treatment. VTE prophylaxis until discharge reached agreement but there was substantial variability regarding the role of extended prophylaxis. Conclusions There is agreement between Canadian clinicians treating patients with thoracic malignancies regarding most risk factors for VTE, but there is no agreement on timing of initiation of prophylaxis, the agents used or factors mandating usage of extended prophylaxis.

    Antibiotic prophylaxis has been employed to reduce the risk of infection. Many reports have documented the role of prophylactic antibiotics on the subsequent development of infection in patients undergoing surgical as well as a variety of percutaneous interventions including cardiac, vascular, biliary, genitourinary, and drainage of fluid collections. While prophylactic antibiotics can be critically important for certain procedures, their use can be associated with allergic reactions (including anaphylaxis), development of bacterial resistance, and increased costs of medical care. In this analysis, we report the incidence of clinical infection following minimally invasive interventions for dialysis access procedures. Hemodialysis (HD) and peritoneal dialysis (PD) patients undergoing consecutive percutaneous interventions (n = 3162) for HD and PD access were included in this study. Procedure-related clinical infection was defined as the presence of fever/chills, tenderness, erythema, swelling within 72 hours postprocedure. The procedures included percutaneous balloon angioplasty (arterial and venous) [n = 2078 (AVF = 1310; AVG = 768)], venography for vascular mapping (n = 110), endovascular stent insertion (n = 26), intravascular coil placement (n = 31), thrombectomy for an arteriovenous fistula (n = 106), thrombectomy for an arteriovenous graft (n = 110), tunneled hemodialysis catheter (TDC) insertion and exchange (n = 283), TDC removal (n = 160), and insertion of accidentally extruded TDC through the same exit site (n = 9). There were 260 peritoneal dialysis catheter insertions and 15 repositioning procedures. Only patients undergoing TDC insertion for accidentally extruded catheter and PD catheter placement received antibiotic prophylaxis within 1-2 hours before the procedure. Extruded TDC received 1 g of cefazolin while PD catheter insertion had 1 g of intravenous vancomycin. Povidone iodine was used for skin antisepsis in all cases. One patient (0

    The Czech Republic ranks among to the countries with a relatively high body burden of PCBs that used to be produced in former Czechoslovakia, more precisely in Slovakia, until 1984 when the production was abolished. In 1994, nation-wide Environmental Health Monitoring System was implemented in the Czech Republic. Indicator PCB congeners and selected chlorinated pesticides started to be monitored in human body fluids and tissues of the Czech population. The indicator PCB levels in breast milk samples showed a significant downward trend in time with regional inter- and intra-individual variability. However, to measure the population body burden of dioxins, blood is considered to be more appropriate than other body fluids. Little has been known about body burden of PCDDs, PCDFs and dioxin-like PCBs in the Czech population. Sporadic data are only available on level of dioxins in the breast milk, or for several pooled blood samples analyzed within the Environmental Health Monitoring System. More than 35 years ago, approximately 80 Czech workers were occupationally exposed to 2,3,7,8- TCDD in a chemical factory producing chlorinated herbicides and pesticides in Central Bohemia. Still in 1996, they showed a mean 2,3,7,8-TCDD plasma level of 256 pg/g fat. It was supposed that also the residents living surrounding the plant might be at increased exposure risk. The objective of this study was (a) to investigate concentrations of PCDDs/PCDFs/PCBs in blood samples from non-occupationally exposed residents living in the vicinity of a chemical plant and (b) to compare the results with the background concentrations available for PCDDs/PCDFs/PCBs in blood samples from the evidently non-exposed Czech population.

    Prophylaxis has dramatically decreased the occurrence of cytomegalovirus (CMV) infection after renal transplantation. Optimal regimens of treatment remain controversial, especially in pediatric recipients. The aim of this study was to evaluate the effectiveness of valganciclovir (VGC) versus aciclovir/valaciclovir (ACV) in a pediatric renal transplant population. Data from 101 renal transplantations were retrospectively analyzed. Except those with R-/Dstatus, all patients received prophylaxis either with ACV, n = 39 or VGC, n = 38. Incidences of positive CMV antigenemia and disease, as well as the delay in relation to the prophylaxis, were collected during at least 12 months after the end of treatment. Positive CMV antigenemia was reported in 34 patients (ACV: 16, VGC: 16, no prophylaxis: 2). CMV disease occurred in 15 patients (ACV: 5; VGC: 8) (ns). For the majority of patients under VGC, positive CMV antigenemia occurred within the year following the withdrawal of prophylaxis (VGC: 14; ACV: 5, P ACV versus two under VGC (P ACV and VGC prophylaxis. However, VGC was more efficient to prevent early CMV infection while patients treated with ACV had less CMV infection or disease after the end of the prophylaxis.

    Prolongation of drug-based thromboembolism prophylaxis after discharge from hospital is clearly recommended following total hip and knee replacement. The aim of this study was to evaluate and compare adherence to and satisfaction with outpatient thromboembolism prophylaxis (by injection and oral) under routine clinical practice conditions. We analysed two consecutive cohorts of patients (480 and 366, respectively) who had undergone total hip or knee replacement surgery in 120 Spanish hospitals, and were prescribed outpatient thromboembolism prophylaxis, by injection and orally, respectively. Information on adherence to and satisfaction with both treatments, sociodemographic data and treatment compliance was collected using specific questionnaires. The drop-out rate (9.49 vs. 4.14%), general satisfaction (37 vs. 83.38%), and the TSQM satisfaction scale were better in the oral prophylaxis cohort and, although the differences between the two routes of administration were not significant, treatment compliance was also better in the oral cohort (Morisky-Green test: 53.49 vs. 59.05%). Adherence to and satisfaction with the oral thromboembolism prophylaxis were better than for prophylaxis by injection in the context of outpatient prolongation. Nevertheless, suboptimal treatment compliance was found in both cohorts, which could result in lack of efficacy of the prophylaxis. Both patients and doctors have to be made aware of the importance of post-discharge extension of thromboprophylaxis in orthopaedic surgery with high thrombotic risk. Moreover, strategies should be developed to encourage compliance. Copyright © 2012 SECOT. Published by Elsevier Espana. All rights reserved.

    2013-01-01

    Full Text Available Objectives. This paper discusses the controversies surrounding the antibiotic prophylaxis preceding dental interventions within the following research question: how effective is dental antibiotic prophylaxis in preventing comorbidity and complications in those at risk? Methods. A synthesis of the available literature regarding antibiotic prophylaxis in dentistry was conducted under the lenses of Kazanjian’s framework for health technology assessment with a focus on economic concerns, population impact, social context, population at risk, and the effectiveness of the evidence to support its use. Results. The papers reviewed show that we have been using antibiotic prophylaxis without a clear and full understanding of its benefits. Although the first guideline for antibiotic prophylaxis was introduced in 1990, it has been revised on several occasions, from 1991 to 2011. Evidence-based clinical guidelines are yet to be seen. Conclusions. Any perceived potential benefit from administering antibiotic prophylaxis before dental procedures must be weighed against the known risks of lethal toxicity, allergy, and development, selection, and transmission of microbial resistance. The implications of guideline changes and lack of evidence for the full use of antibiotic prophylaxis for the teaching of dentistry have to be further discussed.

    Full Text Available Introduction: Southern and Eastern Africa bear the brunt of the AIDS epidemic, and current prevention interventions remain inadequate. Antiretroviral-based pre-exposure prophylaxis (PrEP is gaining momentum as an effective prevention intervention. Discussion: Discussions have been started on how this strategy could be employed in Africa such that the populations most in need can be reached urgently for the greatest impact. This requires the selection of specific risk groups and service environments in which PrEP can be distributed safely and cost effectively while being mindful of any ethical issues. Conclusions: Given the need for an integrated public health approach to this, a number of potential populations and opportunities for PrEP distribution exist and are discussed in this commentary.

Adequate enteral feeding was the most...... frequent reason for discontinuing SUP, but 19% (18/97) continued SUP upon ICU discharge. The majority expressed concern about nosocomial pneumonia and Clostridium difficile infection with the use of SUP. CONCLUSIONS: In this international survey, most participating ICUs reported using SUP, primarily proton...

    Antibiotics are frequently used in dental practice. Clinical and bacteriological epidemiological factors determine the indications of antibiotics in dentistry. Antibiotics are used in addition to appropriate treatment to aid the host defences in the elimination of remaining bacteria. It is indicated when there is evidence of clinical sign involvement and spread of infection. Antibiotics are prescribed in dental practice for treating odontoge nic infections, non-odontogenic infections, as prophylaxis against focal and local infection. Special care needs to be addressed to patients with organ transplants, poorly controlled diabetes and pregnancy. Antibiotics should be used only as an adjunct to dental treatment and never alone as the first line of care. The present paper reviews the indications of antibiotics in dental practice.

    Hernandez, Sergio; Valdes, Jorge; Salama, Moises

    2016-06-01

    Venous thromboembolism (VTE) is a major health concern because it increases morbidity and mortality after a surgical procedure. A number of well-defined, evidence-based guidelines are available delineating suitable use of prophylaxis to prevent deep vein thrombosis and pulmonary embolism. Despite the available literature, there are clear gaps between recommendations and clinical practice, affecting the incidence of VTE. Plastic surgeons underuse the substantiated literature and risk stratification tools that are available to decrease the incidence of VTE in the office-based surgical setting because of fear of bleeding or hematoma complications postoperatively. Venous thromboembolism creates an economic burden on both the patient and the healthcare system. The intent of this literature review is to determine existing VTE risk using assessment models available to aid in the implementation of protocols for VTE prevention, specifically for high-risk cosmetic surgical patients in office-based settings.

    Although several biological agents have been recognized as presenting a significant threat to public health if used in a bioterrorist attack, those that are of greatest importance are known as the Category A agents: Bacillus anthracis (anthrax); variola major (smallpox); Yersinia pestis (plague); Francisella tularensis (tularemia); ribonucleic acid viruses (hemorrhagic fevers); and Clostridium botulinum (botulism toxin). In the previous issue, Part I of this review focused on the clinical presentation and treatment of anthrax, plague, and tularemia. In this second part of this 2-part review of these agents, the focus is on the clinical presentation and treatment of smallpox, viral hemorrhagic fevers, and botulism toxin. The utilization of mass prophylaxis to limit the morbidity and mortality associated with all these agents is also discussed along with the role emergency care personnel play in its implementation.

    Bioterrorism presents a real and omnipresent risk to public health throughout the world. More than 30 biological agents have been identified as possessing the potential to be deployed in a bioterrorist attack. Those that have been determined to be of the greatest concern and possess the greatest potential of use in this arena are known as the Category A agents: Bacillus anthracis (anthrax); Variola major (smallpox); Yersinia pestis (plague); Francisella tularensis (tularemia); viral hemorrhagic fevers; and Clostridium botulinum toxin (botulism toxin). Although the Centers for Disease Control and Prevention utilizes surveillance systems to identify illnesses, the weight of diagnosing, effectively treating, and notifying the appropriate public health officials lies squarely on the shoulders of emergency care personnel. Part I of this two-part review will focus on the clinical presentation and treatment of anthrax, plague, and tularemia. The subsequent Part II of this review will discuss smallpox, viral hemorrhagic fevers, botulism toxin, and the provision of mass prophylaxis.

    Review of antiepileptic drug assessment to date by means of the kindling model of epilepsy suggests that it fills a gap that is evident in standard screening methods such as maximum electroshock or pentylenetetrazol screening tests. However, in order to obtain a comprehensive profile of antiepileptic drugs regarding prophylaxis of developing seizures and treatment of well-established seizures through the kindling preparation, it is desirable to have the following: (1) standardization of kindling techniques, (2) examination of drug effects on developing as opposed to developed seizures, (3) use of a variety of animal species, involving different functional brain sites, and (4) monitoring of plasma levels of the drug administered. It is envisaged that judicious use of the kindling preparation might also enable us to gain some insight into the mechanisms by which drugs produce their prophylactic or therapeutic effect.

    Following a presumptive treatment with 35 mg chloroquine base/kg, 484 Namibian children between 5 months and 5 years of age received 50 mg of proguanil daily for 4 months. They were compared with 268 children living in a very adjacent area who received vitamin tablets after the initial chloroquine medication. Fewer fever episodes were recorded among the children who received proguanil and they were also requiring less presumptive treatments with chloroquine during the period of study, but there were only minor differences in parasite rate between the two groups at the end of the study period. Despite the reduction of morbidity, the required efforts were too large to justify another period of drug prophylaxis.

    Full Text Available Antibiotics are frequently used in dental practice. Clinical and bacteriological epidemiological factors determine the indications of antibiotics in dentistry. Antibiotics are used in addition to appropriate treatment to aid the host defences in the elimination of remaining bacteria. It is indicated when there is evidence of clinical sign involvement and spread of infection. Antibiotics are prescribed in dental practice for treating odontoge nic infections, non-odontogenic infections, as prophylaxis against focal and local infection. Special care needs to be addressed to patients with organ transplants, poorly controlled diabetes and pregnancy. Antibiotics should be used only as an adjunct to dental treatment and never alone as the first line of care. The present paper reviews the indications of antibiotics in dental practice.

    Single-hormone prophylaxis with gestagen (Primolut nor) was carried out on 62 women with uterine bleedings during the premenopause of climacteric at mean age of 46.8 years. A ten-day scheme with application of 5 mg of gestagen daily from 16 to 25 day of the cycle for a period of 6 months was used. The treatment provided stable clinical characteristic of the successive pseudomenstrual cycles could continue for a considerable time practically till disappearance of pseudo-menstruation and transition of the woman in postmenopause. Primolut nor was a convenient drug also in women under continuous anticoagulant treatment. However it was effective and could not be used for treatment of accompanied climacteric symptoms.

    Full Text Available ObjectiveTo investigate the risk factors for antibiotic prophylaxis failure in patients with liver cirrhosis and upper gastrointestinal bleeding. MethodsEighty-two patients with liver cirrhosis and upper gastrointestinal bleeding who were admitted to our hospital from January 2011 to June 2014 were analyzed retrospectively. All patients received third-generation cephalosporins as the antibiotic prophylaxis for 7 days. The therapeutic effect of prophylaxis within two weeks was analyzed, and the clinical features were compared between prophylaxis response group and non-response group. The t-test or Mann-Whitney U test was applied for comparison of continuous data between groups, the chi-square test was applied for comparison of categorical data between groups, and the logistic regression analysis was applied to determine the risk factors for antibiotic prophylaxis failure. ResultsA total of 38 patients (46.4% developed secondary infection. There were significant differences in prothrombin time, proportion of patients admitted to the intensive care unit (ICU, duration of ICU stay, proportion of patients who received deep venipuncture, Child-Pugh classification, and Child-Pugh score between the prophylaxis response group and non-response group (P<0.05. Child-Pugh classification (OR=2.455, 95%CI: 1.01-5.97, P=0.048 and admission to the ICU (OR=4.12, 95%CI: 1.32-12.83, P=0.015 were the independent risk factors for antibiotic prophylaxis failure. ConclusionAntibiotic prophylaxis with third-generation cephalosporins has a high failure rate, and admission to the ICU and a high Child-Pugh classification are the independent risk factors for antibiotic prophylaxis failure.

    Preexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others. 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. 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. 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.).

    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 < 0.0001). There was a significant difference in the SSI rate based on type of preoperative IV 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.

    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.

    The term "invasive candidiasis" encompasses a group of infections of increasing relevance in the intensive care setting. Prophylaxis is an attractive strategy when dealing with diseases of high prevalence, morbidity, and mortality. The success of prophylaxis is determined by the selection of a population at high risk and the use of the safest and most effective drug. Although risk factors for this disease are known, risk assessment strategies need to be developed to predict a high likelihood of disease so that targeted prophylaxis can be offered. Recent advances in antifungal therapy, such as development of the azoles and echinocandins, have resulted in excellent prophylactic and therapeutic choices for the management of this problem.

    Full Text Available Febrile neutropenia remains a major cause of morbidity and mortality in patients receiving chemotherapy. Major prophylactic strategies include granulocyte colony-stimulating factor and antibiotics, the most widely used of which are fluoroquinolones. While fluoroquinolone prophylaxis has been shown to be effective in areas where fluoroquinolone resistance is low, this same efficacy has not been proven in areas where resistance is high, such as in Asia. Given the increase in antimicrobial resistance with the use of prophylaxis, the risks and benefits of this strategy need to be carefully considered. This review presents the evidence for and against fluoroquinolone prophylaxis in areas of high fluoroquinolone resistance.

    Prophylaxis of tumors of the prostate gland is theoretically simple but what makes it difficult is that no appropriate test methods are available. The topic of prostate cancer prophylaxis by dietary supplements remains difficult as there are still no really certain data. The psychological aspect of wanting and being able to actively contribute to success of a therapy oneself, is absolutely not an aspect to be ignored to accept such dietary supplements. There are also studies which show that a certain helpful effect seems to be present. From these considerations the question arises whether cancer prophylaxis could be developed from this. This article presents the state of the art in early 2014.

    Histoplasmosis is the first cause of acquired immunodeficiency syndrome (AIDS) and AIDS-related deaths in French Guiana. Cohort data were used to determine whether primary prophylaxis with 100 mg itraconazole for patients with CD4 counts histoplasmosis for a cost of 36,792 Euros per averted death, 1,533 per life-year saved, 4,415 Euros per averted case, when only counting the costs of itraconazole prophylaxis. Taking into account the total costs of hospitalization showed that primary prophylaxis would allow a savings of 185,178 Euros per year. Even in a scenario of low adherence, primary prophylaxis would be cost-effective in French Guiana, and presumably in the rest of the Guianas and the Amazon.

  3. Antibiotic resistance in Enterobacteriaceae: what impact on the efficacy of antibiotic prophylaxis in colorectal surgery?

    Science.gov (United States)

    Kirby, A; Santoni, N

    2015-04-01

    Antibiotic prophylaxis, introduced in the 1940s, brought in an era of relatively safe colorectal surgery. This was achieved in part due to the prevention of surgical site infections (SSIs) caused by Enterobacteriaceae. Since then, Enterobacteriaceae have become increasingly resistant to the antibiotics commonly used for prophylaxis. The impact of being colonized preoperatively with resistant Enterobacteriaceae on the efficacy of colorectal SSI prophylaxis, if any, is unknown. It is also difficult to predict the likely impact of resistance as the exposure‒response relationships have not been determined for antibiotic surgical prophylaxis. Neither is it known which test for resistance to use; the importance of the concentration of Enterobacteriaceae in the colon, the ability of different species of Enterobacteriaceae to cause SSIs, and the comparative ability of minimum inhibitory concentration or presence of a resistance mechanism in predicting SSI risk have yet to be established. Clinical research is urgently needed to answer these questions.

    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.

    Conclusion: Growing evidence suggests that pre-exposure prophylaxis with tenofovir/emtricitabine during pregnancy and lactation is safe and effective. Shared decision-making provides one approach to identify at-risk women and offers pre-exposure prophylaxis but requires implementation research in diverse clinical settings. Including pregnant and breastfeeding women in future HIV prevention research is critical for the creation of evidence-driven public health policies and clinical guidelines.

    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. Significant risk factors of (GB were mechanical ventilation and loss of consciousness and corticosteroid therapy

    Deep vein thrombosis remains a source of adverse outcomes in surgical patients. Deep vein thrombosis is preventable with prophylactic intervention. The success of noninvasive mechanical modalities for prophylaxis relies on compliance with correct application. The goals of this project were to create a guideline that reflected current evidence and expert thinking about mechanical modalities use, assess compliance with mechanical modalities, and develop strategies to disseminate an evidence-based guideline for deep vein thrombosis prophylaxis.

    Since two large-scale, randomised studies on posaconazole prophylaxis have demonstrated a clear benefit for patients at high risk for contracting invasive fungal disease (IFD), posaconazole prophylaxis has been adopted as standard of care for this patient collective. Several years on from implementation at our institution, we wanted to evaluate its impact on the incidence and use of empirical antifungal therapy in a real-life setting. We analysed retrospectively incidence and severity of IFD in high-risk patients with prophylaxis, using a historical cohort as comparator. A total of 200 patients had either received the extended spectrum triazole posaconazole in prophylactic dosage of 200 mg tid or empirical antifungal therapy. Disease events were analysed by application of the revised EORTC/MSG definitions for IFD. Before posaconazole prophylaxis, we recorded 57/100 cases of IFD which was reduced to 28/100 with prophylaxis. The empirical use of antifungal drugs was reduced to 41% from 91% in the non-prophylaxis cohort. Furthermore, we observed a shift in the categorisation of IFD according to EORTC/MSG criteria. Our data suggest that posaconazole was effective in reducing the rate and probability of invasive fungal disease in high-risk patients.

    Full Text Available Objective: To compare the frequency of fungal infection and mortality rates in patients with hematological malignity and receiving either flucanazole (FLU or posaconazole (POS prophylaxis. Methods: This retrospective, observational study investigated fungal prophylaxis in patients with a high risk of invasive fungal infections (IFIs and diagnosed with hematological malignity at our hospital hematology clinic between 01.01.2011 and 01.01.2013. FLU (n=70 was the prophylactic regimen between 2011 and 2012 which was replaced by POS (n=35 in the following period. The incidence and mortality rates of IFIs developing in the two periods were compared. Results: The incidence of IFI in patients administered FLU prophylaxis was 22/70 (31%, compared to 13/35 (37% in the patients receiving POS. Incidence of invasive pulmonary aspergillosis (IPA in the FLU group was 21/70 (31%, compared to 9/35 (26% in the POS group. The mortality rate in the group receiving FLU prophylaxis was 17 (24%, compared to 4 (11% in the POS group. The difference was attributed to causes other than fungal infection. Results of subgroup analysis performed for AML were similar to the general findings in terms of both incidences of fungal infection and of mortality levels. In multivariate analysis, mean duration of neutropenia was correlated with prophylaxis failure. Conclusion:We conclude that both agents can be successfully used in fungal infection prophylaxis for patients at high risk for IFI. J Microbiol Infect Dis 2014;4(1: 1-6

    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.

    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.

    Full Text Available Abstract Background More than 15 million people worldwide have rheumatic fever (RF and rheumatic heart disease due to RF. Secondary prophylaxis is a critical cost-effective intervention for preventing morbidity and mortality related to RF. Ensuring adequate adherence to secondary prophylaxis for RF is a challenging task. This study aimed to describe the rates of recurrent episodes of RF, quantify adherence to secondary prophylaxis, and examine the effects of medication adherence to the rates of RF in a cohort of Brazilian children and adolescents with RF. Methods This retrospective study took place in the Pediatric Rheumatology outpatient clinic at a tertiary care hospital (Instituto de Puericultura e Pediatria Martagão Gesteira in Rio de Janeiro, Brazil, and included patients with a diagnosis of RF from 1985 to 2005. Results 536 patients with RF comprised the study sample. Recurrent episodes of RF occurred in 88 of 536 patients (16.5%. Patients with a recurrent episode of RF were younger (p Conclusions We recommend implementation of a registry, and a system of active search of missing patients in every service responsible for the follow-up of RF patients. Measures to increase adherence to secondary prophylaxis need to be implemented formally, once non-adherence to secondary prophylaxis is the main cause of RF recurrence. Detection of irregularity in secondary prophylaxis or in appointments should be an alert about the possibility of loss of follow-up and closer observation should be instituted.

  19. Antibiotic prophylaxis for infective endocarditis: ethical care in the era of revised guidelines.

    Science.gov (United States)

    Bach, David S

    Beginning in 1955, the American Heart Association recommended antibiotic prophylaxis among patients with certain structural heart diseases to decrease the likelihood of infective endocarditis (IE) following dental procedures. Over the ensuing 52 years, the American College of Cardiology/American Heart Association (ACC/AHA) guidelines were revised to address gastrointestinal and genitourinary procedures and to modify the assessment of relative risks and specific regimens for prophylaxis. Throughout the various revisions, prophylaxis was recommended for individuals who were at increased risk of developing IE based on best evidence and consensus opinion, albeit in the absence of randomized controlled trials. In 2007, the AHA published a revised guideline statement dramatically restricting its recommendations for antibiotic prophylaxis against IE. In 2008, these views were incorporated in an ACC/AHA guideline update on the management of patients with heart valve disease. The revisions represent a dramatic shift in terms of the patients for whom antibiotic prophylaxis is recommended and the procedures for which it is recommended. What is striking about the new guidelines is that the change in recommendations was based not on new data, but on a change in philosophy despite the lack of new data. To some degree, the arguments for and against antibiotic prophylaxis become those of philosophy, ethics, and the role of evidence-based medicine. This manuscript attempts to briefly examine those arguments and discuss why the revised guidelines may fail to respect the ethical principles of beneficence and patient autonomy.

  1. The population dynamical consequences of density-dependent prophylaxis.

    When infectious disease transmission is density-dependent, the risk of infection will tend to increase with host population density. Since host defence mechanisms can be costly, individual hosts may benefit from increasing their investment in immunity in response to increasing population density. Such "density-dependent prophylaxis" (DDP) has now indeed been demonstrated experimentally in several species. However, it remains unclear how DDP will affect the population dynamics of the host-pathogen interaction, with previous theoretical work making conflicting predictions. We develop a general host-pathogen model and assess the role of DDP on the population dynamics. The ability of DDP to drive population cycles is critically dependent on the time delay between the change in density and the subsequent phenotypic change in the level of resistance. When the delay is absent or short, DDP destabilises the system. As the delay increases, its destabilising effect first diminishes and then DDP becomes increasingly stabilising. Our work highlights the significance of the time delay and suggests that it must be estimated experimentally or varied in theoretical investigations in order to understand the implications of DDP for the population dynamics of particular systems.

    Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy. There is little scientific consensus about how to measure PrEP program implementation progress. We draw on several years of experience in implementing PrEP programs and propose a PrEP continuum of care that includes: (1) identifying individuals at highest risk for contracting HIV, (2) increasing HIV risk awareness among those individuals, (3) enhancing PrEP awareness, (4) facilitating PrEP access, (5) linking to PrEP care, (6) prescribing PrEP, (7) initiating PrEP, (8) adhering to PrEP, and (9) retaining individuals in PrEP care. We also propose four distinct categories of PrEP retention in care that include being: (1) indicated for PrEP and retained in PrEP care, (2) indicated for PrEP and not retained in PrEP care, (3) no longer indicated for PrEP, and (4) lost to follow-up for PrEP care. This continuum of PrEP care creates a framework that researchers and practitioners can use to measure PrEP awareness, uptake, adherence, and retention. Understanding each point along the proposed continuum of PrEP care is critical for developing effective PrEP interventions and for measuring public health progress in PrEP program implementation.

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.

  4. Social prophylaxis: group interaction promotes collective immunity in ant colonies.

    Life in a social group increases the risk of disease transmission. To counteract this threat, social insects have evolved manifold antiparasite defenses, ranging from social exclusion of infected group members to intensive care. It is generally assumed that individuals performing hygienic behaviors risk infecting themselves, suggesting a high direct cost of helping. Our work instead indicates the opposite for garden ants. Social contact with individual workers, which were experimentally exposed to a fungal parasite, provided a clear survival benefit to nontreated, naive group members upon later challenge with the same parasite. This first demonstration of contact immunity in Social Hymenoptera and complementary results from other animal groups and plants suggest its general importance in both antiparasite and antiherbivore defense. In addition to this physiological prophylaxis of adult ants, infection of the brood was prevented in our experiment by behavioral changes of treated and naive workers. Parasite-treated ants stayed away from the brood chamber, whereas their naive nestmates increased brood-care activities. Our findings reveal a direct benefit for individuals to perform hygienic behaviors toward others, and this might explain the widely observed maintenance of social cohesion under parasite attack in insect societies.

    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.

    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.

    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.

    Patients presenting before flight with an upper respiratory infection are at risk for aerosinusitis. Prophylaxis of this condition consists of an oral decongestant before flight and nasal decongestant spray during the flight just prior to descent. Evaluation of the patient presenting with aerosinusitis consists of a careful physical exam with emphasis on diagnosing treatable nasal and sinus pathology. Categorization of the patient into the Weissman classification is important for determining prognostic factors for recovery. Management of this condition is based on the Weissman stage. Stage I or II lesions are generally treated conservatively with a 1-wk course of topical sprays, analgesics, a tapering course of steroids, and oral decongestants. Use of antibiotics is reserved for those cases initiated by bacterial sinusitis. Additionally, antihistamines are reserved for cases where allergies were the inciting cause. Stage III lesions are rarely seen in civilian air travelers due to the relatively low fluctuations in ambient air pressure. Aircrew that suffer Stage III aerosinusitis are at risk for recurrent sinus barotrauma that may require an expertly performed functional endoscopic sinus surgery to successfully manage it.

    The aim of this study is to check the efficacy of acetazolamide in the prophylaxis of vestibular migraine (VM). Treatment options in VM are mainly based on migraine guidelines. We tried to assess the efficacy of acetazolamide in these patients depending on clinical similarities with episodic ataxia type 2 and familial hemiplegic migraine responding to the drug. This is a retrospective cohort study. Among 50 patients with VM and prescribed acetazolamide 500 mg/day, 39 patients were studied as five had been lost on follow-up and six had stopped taking the drug due to side effects. Vertigo and headache frequency determined by number of attacks per month, and the severity determined by visual analog scales measured in centimeters from 0 to 10 were collected from the records. Initial reported figures for frequency and severity were compared with the results gathered after 3 months of treatment. The results were compared. Acetazolamide was effective in reducing both the frequency and severity of vertigo and headache attacks and this effect was more prominent for vertigo frequency and severity.

    Full Text Available Background: Injuries with sharp, potentially infected objects represent a danger, particularly due to the possibility of viral transmission, such as hepatitis B, hepatitis C and human immunodeficiency virus, and consequentially, the possibility of infections with these viruses. The possibility of a tetanus infection should always be excluded as well. In percutaneous exposure of patient’s blood to hepatitis B the possibility of infection ranges between 5–30%, while in exposure to hepatitis C it is 3–10% and in exposure to human immunodeficiency virus this rate is 0.3% (in exposure of mucous membranes 0.09%.Methods: The prospective investigation carried out in the period from 1997 to July 2004 was aimed at establishing the frequency and type of incidents as well as the categories of the affected health care workers along with the procedures and types of sharp objects involved in those incidents. A protocol with 20 incident-related questions was prepared. Post-exposure prophylaxis (immunoprophylaxis against hepatitis B (specific anti-hepatitis B immunoglobulin and/or anti-hepatitis B virus vaccine and against human immunodeficiency virus infection (chemoprophylaxis was carried out by infectologists according to state-of-the-art doctrine. Considering the possibility of infection with hepatitis B virus, hepatitis C virus and human immunodeficiency virus, the injured persons were subjected to a clinical, laboratory and serological follow up for at least 6 months or more following the incident. Exactly the same follow-up approach after injury was used also in the rest of the injured persons from Celje region. In co-operation with the Commission for Control of Nosocomial Infections, the infectologists prepared written guidelines regarding the post-exposure prophylaxis for health care workers in hospitals with the risk for hepatitis B virus, hepatitis C virus and human immunodeficiency virus transmission, and also participated in the implementation

    The Pro-FEIBA study reported health-related quality of life (HRQoL) improved following 6-month of Factor Eight Inhibitor Bypassing Activity (FEIBA) prophylaxis. This study investigates whether 12-month of FEIBA prophylaxis improved HRQoL in haemophilia patients with inhibitors. Thirty-six subjects in a 1-year prospective, randomized, open-label, parallel-design study were randomized to prophylaxis (85 ± 15 U kg(-1) every other day) or on-demand treatment. HRQoL was assessed at screening, 6 and 12-month termination using the EQ-5D, Haem-A-QoL, Haemo-QoL and a general pain visual analog scale (VAS). To evaluate changes, paired t-tests and criteria for minimally important differences were applied. Repeated measures regression tested the association between annualized bleeding rate (ABR) and physical HRQoL. At 6 and 12 months, prophylaxis subjects reported clinically meaningful improvement in EQ-5D index (mean improvement, 0.10 and 0.08, respectively) and both clinically meaningful and statistically significant improvements in EQ-VAS scores (16.9 and 15.7, respectively; P improvement, 20.3 and 23.2, respectively; both P improvements in Haem-A-QoL Total Score and in four domains: Physical Health, Feeling, View, and Work and School (all P improved HRQoL in inhibitor patients. Subjects with lower ABR reported better physical HRQoL.

    Guidelines recommend surgical antibiotic prophylaxis for clean-contaminated procedures but none for clean procedures. The purpose of this study was to describe variations in surgical antibiotic prophylaxis for outpatient urological procedures at United States children's hospitals. Using the PHIS (Pediatric Health Information System®) database we performed a retrospective cohort study of patients younger than 18 years who underwent clean and/or clean-contaminated outpatient urological procedures from 2012 to 2014. We excluded those with concurrent nonurological procedures or an abscess/infected wound. We compared perioperative antibiotic charges for clean vs clean-contaminated procedures using a multilevel logistic regression model with a random effect for hospital. We also examined whether hospitals that were guideline compliant for clean procedures, defined as no surgical antibiotic prophylaxis, were also compliant for clean-contaminated procedures using the Pearson correlation coefficient. We examined hospital level variation in antibiotic rates using the coefficient of variation. A total of 131,256 patients with a median age of 34 months at 39 hospitals met study inclusion criteria. Patients undergoing clean procedures were 14% less likely to receive guideline compliant surgical antibiotic prophylaxis than patients undergoing clean-contaminated procedures (OR 0.86, 95% CI 0.84-0.88, p variation was seen for hospital level compliance with surgical antibiotic prophylaxis for clean-contaminated procedures (range 9.8% to 97.8%, coefficient of variation 0.36) than for clean procedures (range 35.0% to 98.2%, coefficient of variation 0.20). Hospitals that used surgical antibiotic prophylaxis appropriately for clean-contaminated procedures were likely to use surgical antibiotic prophylaxis inappropriately for clean procedures. More variation was seen in hospital level guideline compliance for clean-contaminated procedures. Copyright © 2017 American Urological

    Introduction Osteonecrosis of the jaw (MRONJ) linked to bisphosphonate treatment has specific characteristics that render its therapeutic management challenging for clinicians. Poor response to standard treatment makes it essential to take special precautions when treating this type of disease; therefore, antibiotic prophylaxis and/or antibiotic therapy have been proposed as effective and helpful tools in these situations. Objectives This article seeks to assess published evidence in order to evaluate the different protocols used for antibiotic prophylaxis and/or antibiotic therapy in the general context of patients treated with bisphosphonates. Material and Methods A literature review of the last 10 years was carried out in PubMed using the following keywords: “antibiotic prophylaxis and osteonecrosis,” “bisphosphonates AND osteonecrosis AND dental management,” “bisphosphonate AND osteonecrosis AND antibiotic prophylaxis AND oral surgery.” A total of 188 articles were obtained, of which 18 were ultimately selected. Results and Discussion In patients treated with oral and intravenous bisphosphonates without chemotherapy-associated osteonecrosis of the jaw, antibiotic prophylaxis prior to oral surgery is an important tool to avoid osteonecrosis and promote healing of the affected area. If the patient previously exhibited chemotherapy-associated osteonecrosis after tooth extraction, antibiotic prophylaxis is indicated to prevent recurrent osteonecrosis and promote healing of the extraction site. If chemotherapy-associated osteonecrosis is already present, antibiotic therapy is a vital part of conservative management to reduce the symptomatology of MRONJ and keep it from worsening. Finally, a lack of clinical data and randomized controlled trials makes it difficult to choose the most appropriate protocol for the various clinical situations studied.

    Venous thromboembolism (VTE) is an important cause of preventable harm in hospitalized patients. The critical steps in delivery of optimal VTE prevention care include (1) assessment of VTE and bleeding risk for each patient, (2) prescription of risk-appropriate VTE prophylaxis, (3) administration of risk-appropriate VTE prophylaxis in a patient-centered manner, and (4) continuously monitoring outcomes to identify new opportunities for learning and performance improvement. To ensure that every hospitalized patient receives VTE prophylaxis consistent with their individual risk level and personal care preferences, we organized a multidisciplinary task force, the Johns Hopkins VTE Collaborative. To achieve the goal of perfect prophylaxis for every patient, we developed evidence-based, specialty-specific computerized clinical decision support VTE prophylaxis order sets that assist providers in ordering risk-appropriate VTE prevention. We developed novel strategies to improve provider VTE prevention ordering practices including face-to-face performance reviews, pay for performance, and provider VTE scorecards. When we discovered that prescription of risk-appropriate VTE prophylaxis does not ensure its administration, our multidisciplinary research team conducted in-depth surveys of patients, nurses, and physicians to design a multidisciplinary patient-centered educational intervention to eliminate missed doses of pharmacologic VTE prophylaxis that has been funded by the Patient Centered Outcomes Research Institute. We expect that the studies currently underway will bring us closer to the goal of perfect VTE prevention care for every patient. Our learning journey to eliminate harm from VTE can be applied to other types of harm. Journal of Hospital Medicine 2016;11:S8-S14. © 2016 Society of Hospital Medicine.

    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.

    Objective: To compare single-dose antibiotic prophylaxis (cefotetan 1 g vs cefoxitin 2 g) in various subpopulations based upon risk factors for postsurgical infection following cesarean section.Methods: Patients undergoing cesarean section from April 1993 through March 1994 were included in a retrospective analysis if either of the above antibiotics were administered, surgery was non-emergent, gestational age was less than 32 weeks, absence of fever or prior antibiotics therapy within 72 hours, and no history of organ transplantation or HIV. Cases classified as high risk for infection: IDDM, obesity, autoimmune disease, sickle cell disease, or corticosteroid use. Cases classified as high risk for endometritis (any 2 factors): labor >12 hours, >4 vaginal examinations, ruptured membranes >9 hours, and internal fetal monitor. Cases were separated into 4 groups: elective vs non-elective, low vs high surgical risk. A chi(2) analysis was used to test for differences in infection rates between groups (P cesarean sections, 385 met criteria for inclusion. Non-elective cases accounted for 77% of cases. Postsurgical infection rate was greater in non-elective cases, 7.4%, vs elective cases, 3.0% (P =.056) as was the rate of endometritis (3.2% vs 1.2%, P =.185). No differences were noted based on antibiotic regimen. Postsurgical infection rate was greater for 28 cases at high risk for both surgical infection and endometritis (17.9%) when compared to all 357 other cases (4.5%), P =.003. No difference was noted for endometritis. Of the 28 cases 28.6% of patients treated with cefoxitin and 7.1% of cases treated with cefotetan developed postsurgical infection (P =.13).Conclusion: Overall cefoxitin and cefotetan provided equivalent clinical outcome. A small subset of patients with multiple risk factors for infection may benefit from cefotetan.

  19. Use of Probiotics as Prophylaxis for Postoperative Infections

    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

Primary or secondary antifungal prophylaxis is recommended for patients with hematological malignancies to reduce the risk of invasive fungal infection (IFI. This study retrospectively evaluated the efficacy and potential harm of administration of primary and secondary antifungal prophylaxis to patients with hematological malignancies at one hospital.Methods: All patients with hematological malignancies older than 14 years of age who had experienced at least one FN attack during chemotherapy while being treated at one hospital between November 2010 and November 2012 were retrospectively evaluated.Results: A total of 282 FN episodes in 126 consecutive patients were examined during a 2-year study period. The mean patient age was 51.73±14.4 years (range: 17–82 years, and 66 patients were male. Primary prophylaxis with posaconazole was administered to 13 patients and systemic antifungal treatment under induction or consolidation chemotherapy to seven patients. Of 26 patients who received secondary antifungal prophylaxis with either oral voriconazole (n=17 or posaconazole (n=6 during 46 FN episodes, systemic antifungal therapy was administered in 16 of 38 episodes and three of eight episodes, respectively. Secondary antifungal prophylaxis with caspofungin was found effective in treating six FN episodes in three patients who had experienced at least two persistent candidemia attacks. The mortality rates associated with IFI were 9% in the first year, 2% in the second year, and 6% overall. The mortality rates associated with candidemia

    We analyzed 369 patients with no prior Mycobacterium avium complex (MAC) infection and CD4 60 days and 19% had HIV RNA 10,000 copies/mL. Eleven patients had MAC infection within 6 months baseline (rate = 0.6/100 person months): 4/175 on MAC prophylaxis vs. 7/194, no MAC prophylaxis (p = 0.64). Of the 11 patients, seven had HIV RNA > 10,000, and three > 1000–9999 copies/mL at baseline (one missing). Median time to MAC infection was 62 days (IQR 43–126, maximum 139 days). No MAC infection occurred among 71 (19%) patients virologically suppressed (HIV RNA < 1000 copies/mL) at baseline, including 41 patients with no MAC prophylaxis during follow-up. A small number of eligible virologically suppressed participants and the lack of data on cART/MAC prophylaxis adherence limited our observational nonrandomized study. Primary MAC prophylaxis may not be required for cART-virologically suppressed patients with CD4 < 50 cells/mL. PMID:24833016

    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.

    Full Text Available Objectives. Haemophilia A is a congenital disorder of coagulation that mainly affects males and causes a considerable use of resources, especially when hemophilic patients are treated with prophylaxis. The aim of the present review was to discuss and appraise the methodological aspects and results of published economic evaluations of haemophilia A treatments in the last decade. Methods. The literature search, performed by consulting four engines, covered studies published between 2002 and 2014. Full economic evaluations published in English language were identified and included in the review. A quality assessment of the studies was also carried out based on Drummond’s checklist. Results. After careful evaluations of the identified records, 5 studies were reviewed. Primary and secondary prophylaxis resulted cost-effective compared to on-demand therapy: the ICER of primary prophylaxis ranged from €40.236 to €59.315/QALY gained, while the ICER of secondary prophylaxis was €40.229/QALY gained. Furthermore, 60% were high quality and 40% were medium quality studies. Conclusions. The review underlines the cost-effectiveness of prophylaxis versus on-demand treatment and the different methodological approaches applied. Further economic evaluations are required with models that reflect the clinical reality and consumption of resources in each country.

    The efficacy of intermittent rectal diazepam prophylaxis is assessed in the prevention of febrile seizures. In a prospective randomized cohort trial, 139 children (77 girls, 62 boys) who experienced a first febrile seizure were allocated to two groups: group A, which received intermittent diazepam (n = 68), and group B, which received no prophylaxis (n = 71). All children had a 3-year follow-up. The inclusion criteria were no personal history of afebrile seizures, normal neurodevelopment, no previous anticonvulsant therapy, and age between 6 months and 3 years. Each group was stratified to low, intermediate, and high risk according to the available clinical data. The 36-month recurrence rates in the no-prophylaxis group were 83% in high-risk patients, 55% in intermediate-risk patients, and 46% in low-risk patients. In the prophylaxis group, the recurrence rates were reduced in all risk groups: 38%, 35%, and 33%, respectively. Intermittent diazepam prophylaxis reduces the recurrence rate mainly in high-risk children provided that sufficient doses are given on time and adequately.

    Full Text Available We conducted a mixed-methods study to examine serodiscordant and seroconcordant (HIV-positive/HIV-positive male couples' PrEP awareness, concerns regarding health care providers offering PrEP to the community, and correlates of PrEP uptake by the HIV-negative member of the couple.Qualitative sub-study included one-on-one interviews to gain a deeper understanding of participants' awareness of and experiences with PrEP and concerns regarding health care providers offering PrEP to men who have sex with men (MSM. Quantitative analyses consisted of a cross-sectional study in which participants were asked about the likelihood of PrEP uptake by the HIV-negative member of the couple and level of agreement with health care providers offering PrEP to anyone requesting it.We used multivariable regression to examine associations between PrEP questions and covariates of interest and employed an inductive approach to identify key qualitative themes.Among 328 men (164 couples, 62% had heard about PrEP, but approximately one-quarter were mistaking it with post-exposure prophylaxis. The majority of participants had low endorsement of PrEP uptake and 40% were uncertain if health care providers should offer PrEP to anyone requesting it. Qualitative interviews with 32 men suggest that this uncertainty likely stems from concerns regarding increased risk compensation. Likelihood of future PrEP uptake by the HIV-negative member of the couple was positively associated with unprotected insertive anal intercourse but negatively correlated with unprotected receptive anal intercourse.Findings suggest that those at greatest risk may not be receptive of PrEP. Those who engage in moderate risk express more interest in PrEP; however, many voice concerns of increased risk behavior in tandem with PrEP use. Results indicate a need for further education of MSM communities and the need to determine appropriate populations in which PrEP can have the highest impact.

    The goal of this study was to investigate the toxicity of cefalexin to Pomatoschistus microps juveniles in relation to the presence of microplastics in the water and temperature rise. After acclimatization, groups of wild juveniles were exposed for 96h to artificial salt water (control), microplastics alone (0.184mg/l), cefalexin alone (1.3-10mg/l) and in mixture with microplastics (cefalexin: 1.3-10mg/l; microplastics: 0.184mg/l) at 20 and 25°C. Effect criteria were mortality, post-exposure predatory performance (PEPP), acetylcholinesterase activity (AChE) and lipid peroxidation levels (LPO). At 20°C, concentrations of cefalexin alone≥5mg/l significantly reduced PEPP (up to 56%; 96h-EC50=8.4mg/l), indicating toxicity of the antibiotic to juveniles after short-term exposure to water concentrations in the low ppm range. At 20°C, fish exposed to microplastics alone did not have significant differences in any of the parameters tested relative to the control group but tended to have an inhibition of the PEPP (23%) and AChE (21%); at 25°C, microplastics alone caused mortality (33%) and PEPP inhibition (28%). Thus, microplastics are toxic to P. microps juveniles. At 20°C, under simultaneous exposure to cefalexin and microplastics, the PEPP was significantly reduced (at cefalexin concentrations≥1.25mg/l). Moreover, at 25°C, the toxicity curves of cefalexin (PEPP based), alone and in mixture with microplastics, were significantly different (pmicroplastics in the water influenced the toxicity of cefalexin. The rise of water temperature (from 20°C to 25°C), increased the microplastics-induced mortality (from 8 to 33%), and the inhibitory effects of cefalexin on the PEPP (up to 70%). Significant differences (pmicroplastics and of cefalexin, alone and in mixture with microplastics, to P. microps juveniles. These findings raise concern on the long-term exposure of wild populations to complex mixtures of pollutants, likely decreasing their fitness, and highlight the

    2011-01-01

    Full Text Available The risk of venous thromboembolism (VTE in patients with Neuroleptic malignant syndrome (NMS and those on antipsychotic medications is well established. We present here a case whereby the patient had NMS and developed extensive deep venous thrombosis (DVT despite being on standard DVT Prophylaxis. Our case illustrates that empiric intravenous heparin for the initial few days after the onset of NMS may be considered in those with high risk of VTE, as in such patients standard DVT prophylaxis may not be sufficient. To standardize as to which patients with NMS would be at the highest risk of VTE while on standard DVT prophylaxis, the role of a standardized scoring system and a double-blind randomized trial in the future would probably be beneficial.

    2007-11-01

    This paper reports a prospective audit, against an existing baseline standard, for intermittent pneumatic compression (IPC) in the prophylaxis of asymptomatic deep vein thrombosis (DVT). This was done via a structured questionnaire, using the methodology of total population sampling, encapsulating all theatre staff within one NHS trust. With regards to the standard, performance is good, as IPC is DVT prophylaxis of choice in the perioperative area and is used frequently on most patients. The findings of the audit do, however, highlight the need for appropriate local DVT risk assessment guidelines, essential to ensure that prophylaxis is administered to the correct at risk groups, as prevention may be unjustified in low risk groups and possibly inappropriate for the same regimen to be used for all patients.

We examined characteristics related to tetracycline resistance, including doxycycline exposure, in S. aureus isolates collected via admission surveillance swabs and inpatient clinical cultures from United States military personnel injured during deployment (June 2009-January 2012). Tetracycline class resistance was determined using antimicrobial susceptibility testing. The first S. aureus isolate from 168 patients were analyzed, of which 38 (23%) isolates were resistant to tetracyclines (class). Tetracycline-resistant isolates had a higher proportion of resistance to clindamycin (P=0.019) compared to susceptible isolates. There was no significant difference in tetracycline resistance between isolates collected from patients with and without antimalarial prophylaxis; however, significantly more isolates had tet(M) resistance genes in the doxycycline exposure group (P=0.031). Despite 55% of the patients receiving doxycycline as antimalarial prophylaxis, there was no association with resistance to tetracyclines.

    The subject of this article is employee and his family, employer, the state in all aspects and health as a profit and a lack of health as a loss. Healthy employee brings a profit to himself, to the employer and to the state. Up to these times nobody has thought about the health value. Work is a commodity. Prophylaxis and health promotion are work. Health can be sold as each commodity. Prophylaxis and health promotion incur expenses but they must be compared with illness results expenses (including immeasurable ones). Having analysed the literature the author claims that the thesis is right so it means that the effects of prophylaxis and health promotion determine the profit to employees and their families, to employers and to the state--which means to all of us.

    Background 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. Objectives This updated review aimed to evaluate whether there is still a benefit of reduction in mortality when compared to placebo or no intervention. Search methods 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. Selection criteria 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. Data collection and analysis Two authors independently appraised the quality of each trial and extracted data from the included trials. Analyses were performed using RevMan 5.1 software. Main results 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

    To determine whether a simplified, 1-day/week regimen of trimethoprim/sulfamethoxazole is sufficient to prevent Pneumocystis (jirovecii [carinii]) pneumonia (PCP). Current recommended regimens for prophylaxis against PCP range from daily administration to 3 consecutive days per week dosing. A prospective survey of the regimens adopted for the PCP prophylaxis in all patients treated for childhood cancer at pediatric hematology-oncology centers of the Associazione Italiana Ematologia Oncologia Pediatrica. The 20 centers participating in the study reported a total of 2466 patients, including 1093 with solid tumor and 1373 with leukemia/lymphoma (or primary immunodeficiency; n = 2). Of these patients, 1371 (55.6%) received the 3-day/week prophylaxis regimen, 406 (16.5%) received the 2-day/week regimen, and 689 (27.9%), including 439 with leukemia/lymphoma, received the 1-day/week regimen. Overall, only 2 cases of PCP (0.08%) were reported, both in the 2-day/week group. By intention to treat, the cumulative incidence of PCP at 3 years was 0.09% overall (95% CI, 0.00-0.40%) and 0.51% for the 2-day/week group (95% CI, 0.10%-2.00%). Remarkably, both patients who failed had withdrawn from prophylaxis. A single-day course of prophylaxis with trimethoprim/sulfamethoxazole may be sufficient to prevent PCP in children with cancer undergoing intensive chemotherapy regimens. This simplified strategy might have implications for the emerging need for PCP prophylaxis in other patients subjected to the increased use of biological and nonbiological agents that induce higher levels of immune suppression, such as those with rheumatic diseases.

    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.

    Full Text Available Objective: Aim of this study is to evaluate the efficacy of a phytotherapic which includes Solidago, Orthosiphon and Birch extract (Cistimev® in association with antibiotic prophylaxis in female patients affected by recurrent urinary tract infections (UTIr. 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.

    BACKGROUND Intensive chemotherapy for pediatric acute myeloid leukemia (AML) incurs the risk of infectious complications, but the benefits of antibiotic prophylaxis remain unclear. METHODS In 103 children treated on the AML02 protocol between October 2002 and October 2008 at St. Jude Children’s Research Hospital, we retrospectively assessed the effect of antibiotic prophylaxis on the frequency of febrile neutropenia, clinically or microbiologically confirmed infections (including bacteremia), and antibiotic resistance, and on the results of nasal and rectal surveillance cultures. Initially, patients received no prophylaxis or oral cephalosporin (Group A). Then the protocol was amended to give intravenous cefepime alone or intravenous vancomycin plus either oral cephalosporin, oral ciprofloxacin, or intravenous cefepime (Group B). RESULTS There were 334 infectious episodes. Group A had a significantly greater frequency of documented infections and bacteremia (both P < .0001) (including gram-positive and gram-negative bacteremia, P = .0003 and .001, respectively) than Group B, especially viridans streptococcal bacteremia (P = .001). The incidence of febrile neutropenia without documented infection was not different between the two groups. Five cases of bacteremia with vancomycin-resistant enterococci (VRE) occurred in group B (vs. none in Group A), without related mortality. Two of these cases were preceded by positive VRE rectal surveillance cultures. CONCLUSIONS Outpatient intravenous antibiotic prophylaxis is feasible in children with AML and reduces the frequency of documented infection but not of febrile neutropenia. Despite emergence of VRE bacteremia, the benefits favor antibiotic prophylaxis. Creative approaches to shorten the duration of prophylaxis and thereby minimize resistance should be explored.

    Full Text Available Marion Lee Sanders,1 Anthony James Langone2 1Department of Medicine, Division of Nephrology and Hypertension, University of Iowa, Iowa City, IA, 2Department of Medicine, Division of Nephrology and Hypertension, Vanderbilt University Medical Center, Nashville, TN, USA Abstract: Transplantation is the preferred treatment option for individuals with end-stage renal disease. 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.

    Full Text Available Thrombo-prophylaxis has been shown to reduce the incidence of pulmonary embolism (PE and mortality in surgical patients. The purpose of this review is to find out the evidence-based clinical practice criteria of deep vein thrombosis (DVT prophylaxis in acutely ill medical and critically ill patients. English-language randomized controlled trials, systematic reviews, and meta-analysis were included if they provided clinical outcomes and evaluated therapy with low-dose heparin or related agents compared with placebo, no treatment, or other active prophylaxis in the critically ill and medically ill population. For the same, we searched MEDLINE, PUBMED, Cochrane Library, and Google Scholar. In acutely ill medical patients on the basis of meta-analysis by Lederle et al. (40 trials and LIFENOX study, heparin prophylaxis had no significant effect on mortality. The prophylaxis may have reduced PE in acutely ill medical patients, but led to more bleeding events, thus resulting in no net benefit. In critically ill patients, results of meta-analysis by Alhazzani et al. and PROTECT Trial indicate that any heparin prophylaxis compared with placebo reduces the rate of DVT and PE, but not symptomatic DVT. Major bleeding risk and mortality rates were similar. On the basis of MAGELLAN trial and EINSTEIN program, rivaroxaban offers a single-drug approach to the short-term and continued treatment of venous thrombosis. Aspirin has been used as antiplatelet agent, but when the data from two trials the ASPIRE and WARFASA study were pooled, there was a 32% reduction in the rate of recurrence of venous thrombo-embolism and a 34% reduction in the rate of major vascular events.

    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.

    We conducted a systematic review to evaluate the burden of late vitamin K deficiency bleeding (VKDB) and the effect of vitamin K prophylaxis on the incidence of VKDB. We searched MEDLINE and other electronic databases, and included all observational studies including population surveys as well as randomized controlled trials (RCT). The median (interquartile range) burden of late VKDB was 35 (10.5 to 80) per 100 000 live births in infants who had not received prophylaxis at birth; the burden was much higher in low- and middle-income countries as compared with high-income countries-80 (72 to 80) vs 8.8 (5.8 to 17.8) per 100 000 live births. Two randomized trials evaluated the effect of intramuscular (IM) prophylaxis on the risk of classical VKDB. Although one trial reported a significant reduction in the incidence of any bleeding (relative risk (RR) 0.73, 95% confidence interval (CI) 0.56 to 0.96) and moderate to severe bleeding (RR 0.19, 0.08 to 0.46; number needed to treat (NNT) 74, 47 to 177), the other trial demonstrated a significant reduction in the risk of secondary bleeding after circumcision in male neonates (RR 0.18, CI 0.08 to 0.42; NNT 9, 6 to 15). No RCTs evaluated the effect of vitamin K prophylaxis on late VKDB. Data from four surveillance studies indicate that the use of IM/subcutaneous vitamin K prophylaxis could significantly reduce the risk of late VKDB when compared with no prophylaxis (pooled RR 0.02; 95% CI 0.00 to 0.10). When compared with IM prophylaxis, a single oral dose of vitamin K increased the risk of VKDB (RR 24.5; 95% CI 7.4 to 81.0) but multiple oral doses did not (RR 3.64; CI 0.82 to 16.3). There is low-quality evidence from observational studies that routine IM administration of 1 mg of vitamin K at birth reduces the incidence of late VKDB during infancy. Given the high risk of mortality and morbidity in infants with late VKDB, it seems appropriate to administer IM vitamin K prophylaxis to all neonates at birth. Future studies

    Several international guidelines for treatment and prophylaxis of glucocorticoid-induced osteoporosis (GIO) have been published. Consistent with the development of new therapeutic agents, a different approach to treatment can be recognized depending on the year of publication. Also, new insights for the postmenopausal osteoporosis leave their marks on recent guidelines. The working committee on Osteology of the Austrian Society for Rheumatology and Rehabilitation (ÖGR) sifted through actual guidelines and recent literature on the topic to develop recommendations for the prophylaxis and treatment of the GIO.

  8. Should we definitively abandon prophylaxis for patent ductus arteriosus in preterm new-borns?

    Directory of Open Access Journals (Sweden)

    Vassilios Fanos

    2011-01-01

    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.

    Inga Kirsten

    Full Text Available BACKGROUND: Since 2008, Tanzanian guidelines for prevention of mother-to-child-transmission of HIV (PMTCT recommend combination regimen for mother and infant starting in gestational week 28. Combination prophylaxis is assumed to be more effective and less prone to resistance formation compared to single-drug interventions, but the required continuous collection and intake of drugs might pose a challenge on adherence especially in peripheral resource-limited settings. This study aimed at analyzing adherence to combination prophylaxis under field conditions in a rural health facility in Kyela, Tanzania. METHODS AND FINDINGS: A cohort of 122 pregnant women willing to start combination prophylaxis in Kyela District Hospital was enrolled in an observational study. Risk factors for decline of prophylaxis were determined, and adherence levels before, during and after delivery were calculated. In multivariate analysis, identified risk factors for declining pre-delivery prophylaxis included maternal age below 24 years, no income-generating activity, and enrolment before 24.5 gestational weeks, with odds ratios of 5.8 (P = 0.002, 4.4 (P = 0.015 and 7.8 (P = 0.001, respectively. Women who stated to have disclosed their HIV status were significantly more adherent in the pre-delivery period than women who did not (P = 0.004. In the intra- and postpartum period, rather low drug adherence rates during hospitalization indicated unsatisfactory staff performance. Only ten mother-child pairs were at least 80% adherent during all intervention phases; one single mother-child pair met a 95% adherence threshold. CONCLUSIONS: Achieving adherence to combination prophylaxis has shown to be challenging in this rural study setting. Our findings underline the need for additional supervision for PMTCT staff as well as for clients, especially by encouraging them to seek social support through status disclosure. Prophylaxis uptake might be improved by preponing drug intake to

    We conducted a systematic review to evaluate the burden of late vitamin K deficiency bleeding (VKDB) and the effect of vitamin K prophylaxis on the incidence of VKDB. We searched MEDLINE and other electronic databases, and included all observational studies including population surveys as well as randomized controlled trials (RCT). The median (interquartile range) burden of late VKDB was 35 (10.5 to 80) per 100 000 live births in infants who had not received prophylaxis at birth; the burden was much higher in low- and middle-income countries as compared with high-income countries-80 (72 to 80) vs 8.8 (5.8 to 17.8) per 100 000 live births. Two randomized trials evaluated the effect of intramuscular (IM) prophylaxis on the risk of classical VKDB. Although one trial reported a significant reduction in the incidence of any bleeding (relative risk (RR) 0.73, 95% confidence interval (CI) 0.56 to 0.96) and moderate to severe bleeding (RR 0.19, 0.08 to 0.46; number needed to treat (NNT) 74, 47 to 177), the other trial demonstrated a significant reduction in the risk of secondary bleeding after circumcision in male neonates (RR 0.18, CI 0.08 to 0.42; NNT 9, 6 to 15). No RCTs evaluated the effect of vitamin K prophylaxis on late VKDB. Data from four surveillance studies indicate that the use of IM/subcutaneous vitamin K prophylaxis could significantly reduce the risk of late VKDB when compared with no prophylaxis (pooled RR 0.02; 95% CI 0.00 to 0.10). When compared with IM prophylaxis, a single oral dose of vitamin K increased the risk of VKDB (RR 24.5; 95% CI 7.4 to 81.0) but multiple oral doses did not (RR 3.64; CI 0.82 to 16.3). There is low-quality evidence from observational studies that routine IM administration of 1 mg of vitamin K at birth reduces the incidence of late VKDB during infancy. Given the high risk of mortality and morbidity in infants with late VKDB, it seems appropriate to administer IM vitamin K prophylaxis to all neonates at birth. Future studies

    We report a retrospective and descriptive study of four immunocompromised patients (three with HIV-1 and one with idiopathic CD4+-lymphopenia) with relapsing visceral leishmaniasis seen at the Hospital for Tropical Diseases, London, in whom pentamidine was used as secondary prophylaxis to prevent relapse. Patients experienced between one and four relapses before commencing prophylaxis with subsequent relapse-free periods ranging from 5 to 98 months. Based on these observational data, we recommend large trials to investigate the efficacy of pentamidine over other agents in preventing relapse of VL in the immunocompromised patient.

    Dayer and colleagues recently reported in The Lancet an increased incidence of infective endocarditis in England since 2008, year of NICE guideline on the restriction of antibiotic prophylaxis. They observed a concomitant decrease in the use of antibiotic prophylaxis. The temporal link between reduction of prophylaxis prescribing and increase of infective endocarditis raises the question of whether there is a causal association. In view of this observation, should we rethink antibiotic prophylaxis to prevent infective endocarditis?

  14. Clinical impact of fluoroquinolone-resistant Escherichia coli in the fecal flora of hematological patients with neutropenia and levofloxacin prophylaxis.

    Full Text Available BACKGROUND: Fluoroquinolone prophylaxis in patients with neutropenia and hematological malignancies is said to be effective on febrile netropenia (FN-related infection and mortality; however, the emergence of antibiotic resistance has become a concern. Ciprofloxacin and levofloxacin prophylaxis are most commonly recommended. A significant increase in the rate of quinolone-resistant Escherichia coli in fecal flora has been reported following ciprofloxacin prophylaxis. The acquisition of quinolone-resistant E. coli after levofloxacin use has not been evaluated. METHODS: We prospectively examined the incidence of quinolone-resistant E. coli isolates recovered from stool cultures before and after levofloxacin prophylaxis in patients with neutropenia from August 2011 to May 2013. Some patients received chemotherapy multiple times. RESULTS: In this trial, 68 patients were registered. Levofloxacin-resistant E. coli isolates were detected from 11 and 13 of all patients before and after the prophylaxis, respectively. However, this was not statistically significant (P = 0.65. Multiple prophylaxis for sequential chemotherapy did not induce additional quinolone resistance among E. coli isolates. Interestingly, quinolone-resistant E. coli, most of which were extended-spectrum β-lactamase (ESBL producers, were already detected in approximately 20% of all patients before the initiation of prophylaxis. FN-related bacteremia developed in 2 patients, accompanied by a good prognosis. CONCLUSIONS: Levofloxacin prophylaxis for neutropenia did not result in a significant acquisition of quinolone-resistant E. coli. However, we detected previous colonization of quinolone-resistant E. coli before prophylaxis, which possibly reflects the spread of ESBL. The epidemic spread of resistant E. coli as a local factor may influence strategies toward the use of quinolone prophylaxis.

  17. Pathogenesis, prophylaxis and treatment of infections in patients with chronic lymphocytic leukemia 

    Directory of Open Access Journals (Sweden)

    Full Text Available Chronic lymphocytic leukemia (CLL patients are at high risk for infections. The pathogenesis of infection in patients with this leukemia is complex and multifactorial. Patients with CLL have a number of immune system defects, including disordered B-cell function with decreased production of normal B-cells and abnormal production of immunoglobulins, suppressed Tcell function and neutropenia. Other immune abnormalities present in CLL patients include neutrophil dysfunction, and complement deficiencies. In addition, further perturbations in immune function are related to the antileukemic therapies. Immune disturbance might be common prior to CLL diagnosis and infectious agents could trigger CLL development. Current chemotherapy-based regimens are not curative and often worsen this immune suppression. The introduction of new effective therapeutic agents such as the purine analogues and monoclonal antibodies has influenced the spectrum of infections diagnosed in CLL patients. Some conditions increase the risk for the development of infections including advanced age, decreased levels of immunoglobulins, advanced Binet stage, neutropenia and treatment with more than one line of chemotherapy. Until now it is debatable whether and when antibacterial prophylaxis could be useful in CLL patients. The prevention of infection includes antimicrobial prophylaxis, as well as immunoglobulin replacement and vaccination. Antibacterial prophylaxis should be given to CLL patients with previous severe and/or relapsing bacterial infections. This article reviews the immune defects in CLL and discusses strategies aimed at prophylaxis and treatment of infections in patients with CLL. 

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

    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.

    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.

    Pregnancy is associated with increased risk of venous thromboembolism, especially in the presence of thrombophilia. However, there is no consensus on the optimal approach for thromboprophylaxis in this population. Recent evidence suggests that thrombin generation correlates with the overall procoagulant state of the plasma. Our aim was to evaluate thrombin generation in a prospective cohort of thrombophilic pregnant women, and investigate the effectiveness of low-molecular-weight heparin (LMWH) prophylaxis in pregnancy. Women with severe (n=8), mild (n=47) and no (n=15) thrombophilia were followed throughout their pregnancies. Thrombin generation was evaluated in each trimester as well as five days and eight weeks postpartum (as a reference category). In women undergoing LMWH prophylaxis, thrombin generation and anti-Factor-Xa activity were measured just before and 4 hours after administration (peak effect). Thrombin generation was determined using Technothrombin TGA assay system. For the analysis, median peak thrombin and endogenous thrombin potential were used. Peak thrombin and endogenous thrombin potential were increased during pregnancy compared to the non-pregnant state with the highest results in the severe thrombophilia group. In women receiving LMWH prophylaxis a decrease was observed in thrombin generation at peak effect but over the progression of pregnancy the extent of this decrease reduced in a stepwise fashion. Our results show that thrombin generation demonstrates the hypercoagulable state in thrombophilic pregnancies. In addition, we found the effect of LMWH prophylaxis to progressively decrease with advancing stages of pregnancy.

    Background and purpose - To minimize the risk of hematogenous periprosthetic joint infection (HPJI), international and Dutch guidelines recommended antibiotic prophylaxis prior to dental procedures. Unclear definitions and contradictory recommendations in these guidelines have led to unnecessary antibiotic prescriptions. To formulate new guidelines, a joint committee of the Dutch Orthopaedic and Dental Societies conducted a systematic literature review to answer the following question: can antibiotic prophylaxis be recommended for patients (with joint prostheses) undergoing dental procedures in order to prevent dental HPJI? Methods - The Medline, Embase, and Cochrane databases were searched for randomized controlled trials (RCTs), reviews, and observational studies up to July 2015. Studies were included if they involved patients with joint implants undergoing dental procedures, and either considered HPJI as an outcome measure or described a correlation between HPJI and prophylactic antibiotics. A guideline was formulated using the GRADE method and AGREE II guidelines. Results - 9 studies were included in this systematic review. All were rated "very low quality of evidence". Additional literature was therefore consulted to address clinical questions that provide further insight into pathophysiology and risk factors. The 9 studies did not provide evidence that use of antibiotic prophylaxis reduces the incidence of dental HPJI, and the additional literature supported the conclusion that antibiotic prophylaxis should be discouraged in dental procedures. Interpretation - Prophylactic antibiotics in order to prevent dental HPJI should not be prescribed to patients with a normal or an impaired immune system function. Patients are recommended to maintain good oral hygiene and visit the dentist regularly.

    Full Text Available BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

    Full Text Available Influenza is a major cause of illness and death in residents of long term care facilities for the elderly, in part because residents' age and underlying illness increase the risk of serious complications, and in part because institutional living increases the risk of influenza outbreaks. The administration of antiviral medications active against influenza to persons exposed to influenza has been shown to protect them effectively from illness, and mass antiviral prophylaxis of residents is an effective means of terminating influenza A outbreaks in long term care facilities. The only antiviral currently licensed in Canada for influenza prophylaxis is amantadine, a medication active against influenza A but not influenza B. The National Advisory Committee on Immunization recommends that amantadine prophylaxis be offered to residents when influenza A outbreaks occur in long term care facilities. However, there remain a number of unanswered questions about how best to use amantadine for controlling influenza A outbreaks in long term care facilities. In addition, two members of a new class of antivirals called neuraminidase inhibitors have recently been licensed in Canada for the treatment of influenza, and are effective in prophylaxis. Issues in the use of amantadine in the control of outbreaks of influenza A in long term care facilities for the elderly are reviewed, and the potential uses of neuraminidase inhibitors in this setting are discussed.

    Pharmacological prophylaxis for preventing venous thromboembolism (VTE) is a worldwide established procedure in hip and knee replacement surgery, as well as in the treatment of femoral neck fractures, but few data exist to its regard in other fields of orthopedics and traumatology. Indeed, no guidelines or recommendations are available in the literature, except for a limited number of weak statements about knee arthroscopy and lower limb fractures. The present paper represents the first multidisciplinary effort to provide suggestions on the prophylaxis of VTE in the remaining fields of orthopedic surgery (minor orthopedic surgery and orthopedic trauma). The Italian Society for Studies on Hemostasis and Thrombosis (SISET), the Italian Society of Orthopedics and Traumatology (SIOT) and the association of Orthopedic Traumatology of Italian Hospitals (OTODI) together with the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) and the Italian Society of General Medicine (SIMG) have set down quick and easy suggestions for VTE prophylaxis in a number of surgical conditions for which only scarce evidence is available. This inter-society consensus statement aims at simplifying the approach to VTE prophylaxis in the single patient with the goal of improving its clinical application.

    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.

    Objective. To evaluate the incidence of deep vein thrombosis in hospitalized Chinese medical patients and the impact of DVT prophylaxis. Methods. All cases of confirmed proximal DVT from 1 January 2005 to 31 December 2008 were reviewed retrospectively to determine the presence of risk factors and whether DVT developed: during hospitalization in medical wards or in case of readmission with a diagnosis of DVT within 14 days of discharge from a recent admission to medical wards. The impact of prophylaxis will be estimated by comparing the annual incidence of proximal DVT among medical patients hospitalized from 2005 to 2007 with that of 2008 (DVT prophylaxis commonly used). Results. From 1 January 2005 to 31 December 2008, 3938 Doppler ultrasound studies were performed for suspected DVT. Proximal DVT was diagnosed in 687 patients. The calculated incidence of proximal DVT among medical patients hospitalized for at least two days was 1.8%, 2%, and 1.7% for the year 2005, 2006, and 2007, respectively. The incidence was 1.1% for 2008 (P DVT was substantial in Chinese medical patients, and DVT prophylaxis might reduce such risk.

    Staphylococci are a significant cause of hospital-acquired infection. Nasal carriage of Staphylococcus aureus is an important risk factor for infection in surgical patients and coagulase-negative staphylococci (CNS) are a major cause of prosthetic joint infections. The impact that antibiotic surgical prophylaxis has on the nasal carriage of staphylococci has not been studied. Daily nasal swabs were taken from 63 patients who received antibiotic surgical prophylaxis and 16 patients who received no antibiotics. Total aerobic bacterial count, S. aureus and CNS were enumerated by culture from nasal swabs. Representative isolates were typed by staphylococcal interspersed repeat units (SIRU) typing and PFGE, and MICs to nine antibiotics were determined. After antibiotic administration, there was a reduction in S. aureus counts (median - 2.3 log(10)c.f.u. ml(- 1)) in 64.0 % of S. aureus carriers, compared with only a 0.89 log(10)c.f.u. ml(- 1) reduction in 75.0 % of S. aureus carriers who did not receive antibiotics. A greater increase in the nasal carriage rate of meticillin-resistant CNS was observed after antibiotic surgical prophylaxis compared with hospitalization alone, with increases of 16.4 and 4.6 %, respectively. Antibiotic-resistant S. epidermidis carriage rate increased by 16.6 % after antibiotic administration compared with 7.5 % with hospitalization alone. Antibiotic surgical prophylaxis impacts the nasal carriage of both S. aureus and CNS.

    Full Text Available Aim: to assess the current use of anticoagulants and implementation of International Guidelines in venous thromboembolism (VTE prophylaxis in hospitalized patients with acute medical illnesses in Jakarta, Indonesia. Methods: a multicenter, prospective, disease registry, recruiting patients diagnosed as acutely ill medical diseases and other medical conditions at risk of VTE, with in-hospital immobilization for at least 3 days. Results: of 401 patients, 46.9% received anticoagulants which included unfractionated heparin (64.4%, fondaparinux (11.7%, enoxaparin (9.6%, warfarin (3.7%, and combination of anticoagulants (10.6%. VTE prophylaxis using physical and mechanical method was used in 81.3% of patients, either as a single modality or in combination with anticoagulants. During hospitalization, VTE were found in 3.2% patients; 10 patients (2.5% had lower limb events and 3 patients (0.75% had a suspected pulmonary embolism. The main reference international guidelines used were AHA/ASA 2007 (47.4%, followed by ACCP 2008 (21.7%. Conclusion: the study showed underutilization of prophylaxis anticoagulants in which mechanical thromboprophylaxis either alone or combination with anticoagulants was the most commonly used. Unfractionated heparin was the preferable choice. The most commonly used guideline was AHA/ASA 2007. VTE thromboprophylaxis in medically ill patients needs to be encouraged.

    PROMET is an observational study aimed to assess the management of patients at venous thromboembolism risk in the Algerian hospitals and to evaluate the proportion of at-risk patients treated with an adequate prophylaxis. Following the ENDORSE study achieved five years before with a similar protocol, PROMET included 435hospitalized patients (229 in medical units and 206 in surgical units). Compared to the ENDORSE results, the PROMET data reflect progress in the management of venous thromboembolism: 73.3% of at-risk patients received prophylaxis (57.6% of medical patients and 90.8% of surgical patients). In 93.1% of cases, this prophylaxis was provided by a low molecular weight heparin, mainly at the dose of one injection per day. In medical population, the prescription was triggered by long-term immobilization (P=0.01; OR=5.8 95%CI [1.5-23.0]), associated risk factors (P=0.025; OR=4.13 [1.2-14.2]) and the cause of hospitalization (P=0.056). In surgical departments, the therapeutic decision depended on the nature of the surgical intervention and was influenced by the presence of a contraindication for prophylaxis (Pthromboprophylaxis. The process of preventive treatment (particularly the optimal duration) needs to be clarified.

    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.

    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.

  2. Mechanical prophylaxis of venous thromboembolism in ill hospitalized medical patients: evidence and guidelines

    Full Text Available Venous thromboembolism (VTE represents one of the leading causes of mortality and morbidity in ill medical patients. Avoiding VTE is therefore of utmost importance in clinical practice. VTE prophylaxis can be assured by pharmacological strategies, such as heparinoids, unfractioned heparin, low molecular weight heparins, fondaparinux or oral anticoagulants and, when these are contraindicated, by mechanical measures, such as graduated compression stockings (GCS and/ or intermittent pneumatic compression (ICP. However, due to the lack of solid literature evidence, VTE mechanical prophylaxis is not standardized in hospitalized ill medical patients. Much recently, findings from randomized clinical trials on VTE prophylaxis in ill medical patients, such as CLOTS I in patients with stroke and LIFENOX in patients with other kind of medical diseases, seem to increase doubts and reduce certainness in this context and recommendations from guidelines don’t help in reducing confusion. Therefore the aim of this review is to focus on mechanical prophylaxis of VTE in hospitalized ill medical patients.http://dx.doi.org/10.7175/rhc.v3i3.202

    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 (phypertension. 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

    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

    Urinary tract infections and urosepsis are complications which can precede or follow a kidney stone treatment. Often the stones themselves are the source of infection, whether they are infection stones or not. Systemic infections are difficult to foresee, and neither a pre-operative negative urine culture nor an antibiotic prophylaxis avoid infectious complications for certain. The primary predictive risk factors of urosepsis are: patient conditions, urinary tract infection or a history of recurrent infections, characteristics of the stone, and anatomy of the urinary tract. Infection stones are still a matter of debate, concerning both the aetiology of the disease and its treatment. Positive cultures are not only found with struvite stones, but also with apatite and calcium oxalate stones. Currently, a long-term antibiotic therapy is advised in patients affected by infection stones. Antibiotic therapy should prevent not only septic complications but also recurrence or re-growth of stones after treatment. Different antibiotic modalities are recommended, sometimes together with urease inhibitors. Mid-stream urine culture is the easiest available pre-treatment parameter notwithstanding its poor predictive value. In case of suspected or proven urinary infection, an appropriate antibiotic therapy should always be administered prior to surgical procedure. There is, however, controversy regarding the antibiotic use, its role, expediency, and duration of prophylaxis in relation to the various surgical procedures, and the way infectious complications are considered and classified. When antibiotic prophylaxis is considered, its duration should be clearly established prior to surgery; duration may vary depending on the type of surgery or the type of antibiotic. Furthermore, prophylaxis should be administered only for a limited amount of time. In infection stones, in immuno-compromised patients or in patients with anatomical anomalies or diabetes, the risk of post

    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

    SMX/TMP is the current gold standard for prophylaxis against PCP in immunocompromised pediatric patients. Currently, there are several second-line options for prophylaxis but many, including intravenous (IV) pentamidine, have not been reported to be as effective or as safe as SMX/TMP in the pediatric transplant population. This study is to determine the efficacy and safety of IV pentamidine in preventing PCP in pediatric transplant patients. A retrospective chart review was conducted to evaluate all transplant patients that received at least one dose of IV pentamidine from January 2010 to July 2013. The primary outcome, IV pentamidine efficacy, was evaluated by the incidence of PCP diagnosis for 28 days after the last dose of IV pentamidine if patient was transitioned to another agent for PCP prophylaxis. Patients on IV pentamidine for entire course of PCP prophylaxis were followed at least six months after discontinuation of IV pentamidine. The safety of IV pentamidine was assessed by the incidence of adverse events leading to pentamidine discontinuation. All data were analyzed using descriptive statistics. All transplant patients at CCHMC who had received IV pentamidine were reviewed, and 333 patients met inclusion criteria. The overall incidence of PCP was found to be 0.3% for pediatric transplant patients on pentamidine. Pentamidine was found to be safe, and the incidence of adverse events leading to discontinuation was 6% with the most common reason being tachycardia 2.1%. IV pentamidine is safe and effective as PCP prophylaxis in pediatric transplant patients with a PCP breakthrough rate of 0.3% (1 of 333 patients), and only 20 adverse events led to discontinuation. We recommend that IV pentamidine be considered as a second-line option in pediatric transplant patients who cannot tolerate SMX/TMP.

    The objective of this study was to evaluate the efficacy and safety associated with treatment available to prevent an acute attack of gout when initiating a urate-lowering therapy (ULT). We retrospectively reviewed patients who were diagnosed with gout and treated with ULT during the period from January 2000 to January 2014. They were divided into three groups, 75 patients without prophylaxis treatment, 103 patients treated with etoricoxib, and 129 patients with colchicine treatment. Both demographic and clinical characteristics associated with gout were analyzed. At baseline, demographic and clinical characteristics were generally similar in three groups. SU target level was achieved in 49.3% of the patients without prophylaxis treatment, 66.4% in the etoricoxib group and 65.1% in colchicine group, respectively. During the first 16 weeks, patients without prophylaxis treatment exhibited higher flare rates than patients in other two groups. However, no statistically significant difference was observed between patients in etoricoxib group and colchicine group. In the 16-24 weeks, the proportion of patients who reported flares were all decreased similarly in three groups. The mean number of acute gout flares per patient and gout flare days per patient was significantly higher in patients without prophylaxis treatment than patients in other groups. The mean number of acute gout flares was lower (4.2±2.3 vs 3.2±1.8) in patients with etoricoxib treatment than that in patients with colchicine treatment. Gout flare days per patient were significantly higher in patients without prophylaxis treatment. Compared to colchicine group, gout flare days per patient in etoricoxib were lower (1.2±0.5 vs 2.6±0.6). In term of AEs, patients receiving colchicine had higher rates of gastrointestinal AEs than those who received etoricoxib. In summary, our survey revealed that etoricoxib was more effective and safe than colchicine in preventing acute attack during ULT. PMID:26885092

    Human immunodeficiency virus (HIV)-infected patients receiving highly active antiretroviral therapy (HAART) have experienced a dramatic decrease in Pneumocystis carinii pneumonia (PCP), necessitating reassessment of clinical guidelines for prophylaxis. A simulation model of HIV infection was used to estimate the lifetime costs and quality-adjusted life expectancy (QALE) for alternative CD4 cell count criteria for stopping primary PCP prophylaxis in patients with CD4 cell count increases receiving HAART and alternative agents for second-line PCP prophylaxis in those intolerant of trimethoprim-sulfamethoxazole (TMP/SMX). The target population was a cohort of HIV-infected patients in the United States with initial CD4 cell counts of 350/microL who began PCP prophylaxis after their first measured CD4 lymphocyte count less than 200/microL. Data were from randomized controlled trials and other published literature. For patients with CD4 cell count increases during HAART, waiting to stop prophylaxis until the first observed CD4 cell count was greater than 300/microL prevented 9 additional cases per 1000 patients and cost $9400 per quality-adjusted life year (QALY) gained compared with stopping prophylaxis at 200/microL. For patients intolerant of TMP/SMX, using dapsone increased QALE by 2.7 months and cost $4500 per QALY compared with no prophylaxis. Using atovaquone rather than dapsone provided only 3 days of additional QALE and cost more than $1.5 million per QALY. Delaying discontinuation of PCP prophylaxis until the first observed CD4 cell count greater than 300/microL is cost-effective and provides an explicit "PCP prophylaxis stopping criterion." In TMP/SMX-intolerant patients, dapsone is more cost-effective than atovaquone.

    Conflicting data have been reported on the clinical significance of contrast-induced nephropathy after CT scan (CT-CIN). In addition, the epidemiologic characteristics and clinical outcomes of CT-CIN following proper prophylactic intervention remain elusive.We examined the incidence, risk factors, and outcomes of CT-CIN in stable chronic kidney disease (CKD) patients using data collected from our outpatient CT-CIN prophylaxis program conducted between 2007 and 2014. The program recruited patients with an estimated glomerular filtration rate (eGFR) pop-up alert system and provided an identical protocol of CIN prophylaxis to all patients.A total of 1666 subjects were included in this study, and 61 of the 1666 subjects (3.7%) developed CT-CIN. Multivariate analysis showed that baseline eGFR, diabetes mellitus, and low serum albumin were significant risk factors for CT-CIN. The generalized additive model analysis revealed a nonlinear relationship between the baseline eGFR and the risk of CT-CIN. In this analysis, the risk of CT-CIN began to increase below an eGFR threshold of 36.8 mL/min/1.73 m. To assess the outcomes of CT-CIN, patients with and without CT-CIN were compared after propensity score-based 1:2 matching. CT-CIN did not increase the mortality rate of patients. However, patients with CT-CIN were significantly more likely to start dialysis within 6 months of follow-up, but not after those initial 6 months.CT-CIN developed in only a small number of stable CKD patients who received proper prophylactic intervention, and the risk of CT-CIN was increased in patients with more advanced CKD. Despite the low incidence, CT-CIN conferred a non-negligible risk for the initiation of dialysis in the acute period, even after prophylaxis.

    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.

    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.

    An open, prospective, randomized study was performed to investigate the effect of norfloxacin prophylaxis on stricture formation and operative outcome after transurethral resection of the prostate. After resection, the 359 patients studied were randomly divided into 2 groups: 1) those given norfloxacin as prophylaxis for 15 days following removal of the catheter (norfloxacin group) and 2) those given no antimicrobial prophylaxis during the same period (control group). Of the patients 94 were excluded. At followup 6 to 12 months postoperatively, the number of strictures in the anterior urethra was 2 of 135 in the norfloxacin group and 22 of 130 in the control group (p norfloxacin group, fewer patients in that group were dissatisfied with the operative outcome. The results suggest that norfloxacin provides effective prophylaxis against stricture formation after transurethral resection of the prostate.

    Patients with severe traumatic brain injury (sTBI) are at high risk for developing venous thromboembolism (VTE). Nonetheless, pharmacologic VTE prophylaxis is often delayed out of concern for precipitating extension of intracranial hemorrhage (ICH). The purpose of this study was to compare the effectiveness of early vs late VTE prophylaxis in patients with sTBI, and to characterize the risk of subsequent ICH-related complication. Adults with isolated sTBI (head Abbreviated Injury Scale score ≥3 and total Glasgow Coma Scale score ≤8) who received VTE prophylaxis with low-molecular-weight or unfractionated heparin were derived from the American College of Surgeons Trauma Quality Improvement Program (2012 to 2014). Patients were divided into EP (Propensity score matching was used to minimize selection bias. The primary end point was VTE (pulmonary embolism or deep vein thrombosis). Secondary outcomes were defined as late neurosurgical intervention (≥72 hours) or death. We identified 3,634 patients with sTBI. Early prophylaxis was given in 43% of patients. Higher head injury severity, presence of ICH, and early neurosurgery were associated with late prophylaxis. Propensity score matching yielded a well-balanced cohort of 2,468 patients. Early prophylaxis was associated with lower rates of both pulmonary embolism (odds ratio = 0.48; 95% CI, 0.25-0.91) and deep vein thrombosis (odds ratio = 0.51; 95% CI, 0.36-0.72), but no increase in risk of late neurosurgical intervention or death. In this observational study of patients with sTBI, early initiation of VTE prophylaxis was associated with decreased risk of pulmonary embolism and deep vein thrombosis, but no increase in risk of late neurosurgical intervention or death. Early prophylaxis may be safe and should be the goal for each patient in the context of appropriate risk stratification. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc.

    Controversy exists regarding antibiotic prophylaxis before shock wave lithotripsy. The AUA (American Urological Association) guideline recommends universal antibiotic prophylaxis, whereas the EAU (European Association of Urology) guideline recommends prophylaxis only for select patients. We evaluated the use of targeted antibiotic prophylaxis in preventing urinary tract infections in patients undergoing shock wave lithotripsy. A prospective single cohort study was performed during 6 months with patients undergoing shock wave lithotripsy. All patients underwent urine dipstick and culture before shock wave lithotripsy. Targeted antibiotic prophylaxis was provided at the discretion of the treating urologist. All patients had a urine culture performed after shock wave lithotripsy and completed a survey documenting fevers or urinary symptoms. The primary outcome was the incidence of urinary tract infections, urosepsis and asymptomatic bacteriuria after shock wave lithotripsy. The secondary outcome was the sensitivity and specificity of urinary dipstick leukocytes and nitrites. A total of 526 patients were enrolled in the study. Of the 389 patients included in the determination of the primary outcome, urinary tract infection developed in only 1 (0.3%), urosepsis did not develop in any patients and asymptomatic bacteriuria developed in 11 (2.8%). Eight (2.1%) patients were administered antibiotic prophylaxis. The specificity of urine dipstick nitrites was high (95%) while the sensitivity was poor (9.7%). In our cohort study using targeted antibiotic prophylaxis the rates of urinary tract infection after shock wave lithotripsy and rates of asymptomatic bacteriuria were extremely low, with no development of urosepsis. This finding questions the need for universal antibiotic prophylaxis before shock wave lithotripsy. Copyright © 2013 American Urological Association Education and Research, Inc.

    2010-01-01

    Life-threatening in the short term and leading to a high level of morbidity in the long term, venous thromboembolism (VTE) is the most fearful complication following lower limb arthroplasty. With advances in surgical procedure, anesthetic management and postoperative convalescence have altered the risks of venous thromboembolism after total joint arthroplasty in the lower extremity.The pathogenesis of VTE is multifactorial and includes the well-known Virchow's triad of hypercoagulability, venous stasis and endothelial damage. Therefore, it is appropriate to use a multimodal approach to thromboprophylaxis. Despite extensive research, the ideal multimodal prophylaxis against venous thrombolism has not been identified. So this article reviews the recent developments in multimodal prophylaxis for thromboembolism after total joint arthroplasty.

    2011-01-01

    Full Text Available Respiratory syncytial virus (RSV is a common infection in infancy, with nearly all children affected by two years of age. Approximately 0.5% to 2.0% of all children are hospitalized with lower respiratory tract disease, of which 50% to 90% have bronchiolitis and 5% to 40% have pneumonia. Morbidity and mortality are highest in children with nosocomial infection and in those with underlying medical illnesses such as cardiac and chronic lung disease. Aboriginal children residing in remote northern regions are specifically considered to be at high risk for hospitalization due to RSV infection. Thorough hand washing and health education are the principal strategies in primary prevention. In the absence of a vaccine, palivizumab prophylaxis is currently the best intervention to reduce the burden of illness and RSV-related hospitalization in high-risk children. Health care professionals should provide palivizumab prophylaxis cost effectively in accordance with recommendations issued by pediatric societies and national advisory bodies.

    Full Text Available Objective.To reveal the behavior of couples who face prophylaxis of vertical transmission of HIV. Methodology. This study, based on Heidegger's theory of phenomenology, included 14 participants (7 couples, who received prophylaxis against HIV vertical transmission. The study was conducted from February 2011 to December 2012 in a prenatal outpatient and child care unit at a hospital in the countryside of Rio Grande do Sul, Brazil. Results. Given the possibility of infection and of having a child, the couples revealed the existential movement of staying together to face the situation. The couple learn to take care of themselves in order to be able to care for and become involved with the baby. In this relationship, they teach themselves how to be a family. Conclusion. The inclusion of men in women's health care process, with both serving as a unit, makes it possible to develop assistance in the context of considering the family as being a participant in care.

    The US Public Health Emergency Medical Countermeasures Enterprise convened subject matter experts at the 2010 HHS Burkholderia Workshop to develop consensus recommendations for postexposure prophylaxis against and treatment for Burkholderia pseudomallei and B. mallei infections, which cause melioidosis and glanders, respectively. Drugs recommended by consensus of the participants are ceftazidime or meropenem for initial intensive therapy, and trimethoprim/sulfamethoxazole or amoxicillin/clavulanic acid for eradication therapy. For postexposure prophylaxis, recommended drugs are trimethoprim/sulfamethoxazole or co-amoxiclav. To improve the timely diagnosis of melioidosis and glanders, further development and wide distribution of rapid diagnostic assays were also recommended. Standardized animal models and B. pseudomallei strains are needed for further development of therapeutic options. Training for laboratory technicians and physicians would facilitate better diagnosis and treatment options.

    Full Text Available Malaria is one of the most common infectious diseases, resulting in the deaths of millions of children around the world. The disease causes approximately half a million to 2.5 million people to die annually. People can only get malaria by being bitten by an infective female Anopheles mosquito that transmits malaria from infected individuals. The increase in international travel and the spread of malaria around the world has resulted in an increased risk of malaria infection. Prophylactic drugs are used to prevent the spread of malaria and to protect individuals in endemic areas. The most efficacious drug for treatment and prophylaxis against malaria is mefloquine (MQ, an antimalarial drug used especially as a prophylaxis against Plasmodium falciparum and as a treatment for malaria. MQ is also used to prevent the treatment of chloroquine-resistant P. falciparum malaria. This review focuses on the advantages of MQ and its adverse events.

  13. Trophallaxis and prophylaxis: social immunity in the carpenter ant Camponotus pennsylvanicus.

    Hamilton, Casey; Lejeune, Brian T; Rosengaus, Rebeca B

    2011-02-23

    In social insects, group behaviour can increase disease resistance among nest-mates and generate social prophylaxis. Stomodeal trophallaxis, or mutual feeding through regurgitation, may boost colony-level immunocompetence. We provide evidence for increased trophallactic behaviour among immunized workers of the carpenter ant Camponotus pennsylvanicus, which, together with increased antimicrobial activity of the regurgitate droplet, help explain the improved survival of droplet recipient ants relative to controls following an immune challenge. We have identified a protein related to cathepsin D, a lysosomal protease, as a potential contributor to the antimicrobial activity. The combined behavioural and immunological responses to infection in these ants probably represent an effective mechanism underlying the social facilitation of disease resistance, which could potentially produce socially mediated colony-wide prophylaxis. The externalization and sharing of an individual's immune responses via trophallaxis could be an important component of social immunity, allowing insect colonies to thrive under high pathogenic pressures.

    Transdermal clonidine has recently been reported to be efficacious in the prophylaxis of cluster headache. A 2-week course of transdermal clonidine (5 mg the first week, 7.5 mg the second week) preceded by a 5-day run-in period, was administered to 16 patients with episodic cluster headache in an active cluster period. In 5 patients, the painful attacks disappeared after the seventh day of treatment. For the group as a whole, no significant variations in headache frequency, pain intensity, or attack duration were observed between the run-in period and the first and second weeks of treatment (ANOVA). Further studies are necessary to clarify the effectiveness of transdermal clonidine in the prophylaxis of episodic cluster headache.

    Full Text Available Role of propranolol and cyproheptadine in the prophylaxis of migraine was studied in a controlled double blind trial. Two hundred fifty-nine patients were divided into four groups. Each group was either given a placebo, cyproheptadine, propranolol or a combination of the latter two drugs. The patients were followed for a period of three months. Significant relief in frequency, duration and severity from migranous attacks was seen in all drug treated groups over placebo. Significant correlation in response was seen in frequency, duration and severity in all the groups which received drugs. Statistically more significant relief was seen in cyproheptadine and propranolol treated group as compared to individual drug treated groups. In cyproheptadine and propranolol treated groups, the dropout rate was lower and associated symptoms were better relieved than in other groups. The study shows efficacy of combination of cyproheptadine and propranolol in migraine prophylaxis.

    A number of studies were published with contradictory results comparing tacrolimus (Tac) and cyclosporine A (CsA) for graft-versus-host disease (GVHD) prophylaxis, but there are only few that accounted for pharmacokinetic (PK) parameters. In this study, we created a model based on median concentrations, variability of concentrations, and failures to maintain target levels that distinguished patients with low, intermediate, and high risks of acute GVHD (hazard ratios (HR) 1.77, 95%CI 1.36-2.32, p  0.05). Patients in the Tac group had better GVHD relapse-free survival (HR = 0.659, p = 0.01) and comparable overall survival (p > 0.05). In conclusion, PK risk should be accounted for in comparisons of GVHD prophylaxis regimens with calcineurin inhibitors, and Tac was superior to CsA in patients with high, but not intermediate and low PK risk.

    Full Text Available Abstract Background DVT is the main cause of death in hospitalized patients and thromboprophylaxis is the only way to prevent these deaths. International recommendations suggested that active monitoring of DVT/PE prophylaxis can improve the efficacy in Hospitals. Methods We performed a cohort study in three consecutives periods to evaluate DVT prophylaxis in 388 adults hospitalized in a General Hospital. Results 85% of the population had high risk factors for DVT. Thromboprophylaxis was in accordance with local and International guidelines (ACCP 2008 in 72.7% and 86% of the patients respectively. No significant difference could be founded between clinical and surgical patients. One every 10 patients received higher prophylaxis than suggested by guidelines and two out of ten received deficient or no prophylaxis. The worst 2 groups of patients were those with moderate/low risk of DVT and the group with a contraindication to pharmacologic prophylaxis. We observed a progressive improvement of the DVT prophylaxis in the 3 periods of evaluation. Conclusions Although the rate of recommended thromboprophylaxis is higher than many other reports in the region we still have some areas where we need to improve. Regular audits like these are very helpful to find out what specific areas of the hospital needs some careful attention in order to have a better quality of assistance.

The guideline which was proposed by AHA has been updated 9 times having the last update published in 2007. This study was endeavored to uncover the level of knowledge of general dental practitioners in Shiraz, concerning the 2007 AHA guidelines for endocarditis prophylaxis in patients with cardiac problems receiving dental treatments.Materials and Method: This cross- sectional and descriptive analytical study included 150 dentists as participants. All practitioners were given a self –report questionnaire which consisted of three sections. Questions were designed to assess their knowledge of antibiotic prophylaxis in patients with cardiac disease. Results: Almost all participants (93% were aware of antibiotic prophylaxis to be essential for tooth extraction. Most participants did not believe in prophylaxis for noninvasive procedures (such as shedding of primary teeth, impression, intraoral radiography. From all of the respondents, 75% considered Amoxicillin to be the anti-biotic of choice and 57% were acquainted with the correct dose of Amoxicillin for high risk patients.Conclusion: The study identified a potential for under/over prescription of antibiotic prophylaxis under the current guideline. Burden of IE necessitates more accurate knowledge of antibiotic prophylaxis in the undergraduate curriculum and continuing education programs of dentistry.

    1. The risk of parasitism and infectious disease is expected to increase with population density as a consequence of positive density-dependent transmission rates. Therefore, species that encounter large fluctuations in population density are predicted to exhibit plasticity in their immune system, such that investment in costly immune defences is adjusted to match the probability of exposure to parasites and pathogens (i.e. density-dependent prophylaxis).

A risk-assessment algorithm was created based on the results of the review.Data synthesis: Several VTE RFs have enough evidence to support RECs for prophylaxis in hospitalized medical patients (eg, increasing age, heart failure, and stroke. Other factors are considered adjuncts of risk (eg, varices, obesity, and infections. According to the algorithm, hospitalized medical patients ≥40 years-old with decreased mobility, and ≥1 RFs should receive chemoprophylaxis with heparin, provided they don’t have contraindications. High prophylactic doses of unfractionated heparin or low-molecular-weight-heparin must be administered and maintained for 6–14 days.Conclusions: A multidisciplinary group generated evidence-based RECs and an easy-to-use algorithm to facilitate VTE prophylaxis in medical patients

    Antibiotic prophylaxis is commonly used in head and neck oncologic surgery, due to the clean-contaminated nature of these procedures. There is a wide variety in the use of prophylactic antibiotics regarding the duration of application and the choice of agent. The purpose of this study was to determine whether short-term or long-term antibiotic prophylaxis has an impact on the development of head and neck surgical wound infection (SWI). Retrospective chart review was carried out in 418 clean-contaminated head and neck surgical oncology cases at our department. More than 50 variables including tumour type and stage, type of surgical treatment, co-morbidities, duration and choice of antibiotic prophylaxis, and the incidence of SWI were analysed. Following descriptive data analysis, Chi square test by Pearson and Fisher's exact test were used for statistical evaluation. Fifty-eight of the 418 patients (13.9 %) developed SWI. Patients with advanced disease and tracheotomy showed a significantly higher rate of SWI than those with early stage disease and without tracheotomy (p = 0.012 and p = 0.00017, respectively). However, there was no significant difference between the SWI rates in the short term and long term treatment groups (14.6 and 13.2 %, respectively; p = 0.689). Diabetes and body weight were not found to be risk factors for SWI. Long-term antibiotic prophylaxis was not associated with a decrease in SWI in the entire cohort of patients undergoing clean-contaminated major head and neck oncologic surgery. Our data confirmed the extent of surgery and tracheotomy as being risk factors for postoperative SWI.

    2012-03-01

    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.

  9. Prophylaxis for acute gout flares after initiation of urate-lowering therapy.

    2014-11-01

    This review summarizes evidence relating to prophylaxis for gout flares after the initiation of urate-lowering therapy (ULT). We searched MEDLINE via PubMed for articles published in English from 1963 to 2013 using MEsH terms covering all aspects of prophylaxis for flares. Dispersion of monosodium urate crystals during the initial phase of deposit dissolution with ULT exposes the patient to an increased rate of acute flares that could contribute to poor treatment adherence. Slow titration of ULT might decrease the risk of flares. According to the most recent international recommendation, the two first-line options for prophylaxis are low-dose colchicine (0.5 mg once or twice a day) or low-dose NSAIDs such as naproxen 250 mg orally twice a day. They can be given for up to 6 months. If these drugs are contraindicated, not tolerated or ineffective, low-dose corticosteroids (prednisone or prednisolone) might be used. Recently, reports for four trials described the efficacy of canakinumab and rilonacept, two IL-1 inhibitors, for preventing flares during the initiation of allopurinol therapy. Prophylaxis for flares induced by ULT is an important consideration in gout management. Low-dose colchicine and low-dose NSAIDs are the recommended first-line therapies. Although no IL-1 blockers are approved as prophylactic treatment, this class of drug could become an interesting option for patients with gout with intolerance or contraindication to colchicine, NSAIDs or corticosteroids. © The Author 2014.

    The geko™ device is a single-use, battery-powered, neuromuscular electrostimulation device that aims to reduce the risk of venous thromboembolism (VTE). The National Institute for Health and Care Excellence (NICE) selected the geko™ device for evaluation, and invited the manufacturer, Firstkind Ltd, to submit clinical and economic evidence. King's Technology Evaluation Centre, an External Assessment Centre (EAC) commissioned by the NICE, independently assessed the evidence submitted. The sponsor submitted evidence related to the geko™ device and, in addition, included studies of other related devices as further clinical evidence to support a link between increased blood flow and VTE prophylaxis. The EAC assessed this evidence, conducted its own systematic review and concluded that there is currently limited direct evidence that geko™ prevents VTE. The sponsor's cost model is based on the assumption that patients with an underlying VTE risk and subsequently treated with geko™ will experience a reduction in their baseline risk. The EAC assessed this cost model but questioned the validity of some model assumptions. Using the EACs revised cost model, the cost savings for geko™ prophylaxis against a 'no prophylaxis' strategy were estimated as £197 per patient. Following a second public consultation, taking into account a change in the original draft recommendations, the NICE medical technologies guidance MTG19 was issued in June 2014. This recommended the adoption of the geko™ for use in people with a high risk of VTE and when other mechanical/pharmacological methods of prophylaxis are impractical or contraindicated in selected patients within the National Health Service in England.

    To estimate the incidence of first-responder visits to emergency departments (EDs) for blood or body fluid exposures, elucidate any temporal patterns of these visits, and quantify human immunodeficiency virus (HIV) postexposure prophylaxis (PEP) utilization for these exposures. This was a retrospective study of first responders presenting to Rhode Island EDs for blood or body fluid exposures from 1995 to 2001. Incidence rates for exposures with 95% confidence intervals (CIs) were estimated. Temporal trends for visits were modeled. Factors associated with HIV PEP utilization were identified using logistic regression. Odds ratios (ORs) with 95% CIs were estimated. The average incidence rate of ED visits for blood or body fluid exposures was 23.29 (20.07-26.52) ED visits per 100,000 ambulance runs. The incidence rose between 1995 and 1999 and then decreased. First-responder ED visits were lowest in October and highest in April and were lowest at 7 am and highest at 7 pm. First responders presenting with a percutaneous or blood-to-mucous membrane exposure had a 4.13 (1.82-8.89) greater odds and those exposed to a known HIV-infected source had a 9.03 (1.59-51.26) greater odds of being offered HIV PEP. First responders presenting to a teaching hospital had a 2.21 (1.02-4.77) greater odds of being offered prophylaxis and a 4.20 (1.08-16.32) greater odds of accepting prophylaxis when it was offered. First responders face a risk of blood or body fluid exposure that varies over the course of the day and the year. HIV PEP is more likely to be used if the exposures are percutaneous, or blood-to-mucous membrane, or if the source is known to be HIV-infected. Standardization of protocols across EDs for administering HIV prophylaxis appears to be needed.

    Bowman, J M; Pollock, J M

    1978-03-18

    Two (0.18%) of 1086 Rh-negative primigravidas or multigravidas treated similarly in all previous pregnancies, who were given a single injection of Rh immune globulin (300 mug) at 28 weeks' gestation and subsequently were delivered of Rh-positive babies, had demonstrable Rh isoimmunization at the time of that injection and must be considered "logistic" failures of antenatal prophylaxis. The remaining 1084 (who were treated again after delivery) had no evidence of Rh isoimmunization at delivery and none of the 512 screened at 6 months after delivery appeared to be immunized. If the 28th-week injection had not been protective, one would have expected 14 of the 1084 to have been demonstrably Rh isoimmunized and evidence of Rh isoimmunization to have persisted in 6 of the 512 observed 6 months after delivery.Six of 719 Rh-negative multigravidas who had not received Rh immune globulin after previous pregnancies or had been treated only after delivery showed evidence of Rh isoimmunization despite a single injection of Rh immune globulin at 28 weeks in a subsequent pregnancy. In three of the six the cause was most likely "sensibilization" due to previous exposure to Rh-positive blood or an untreated Rh-positive pregnancy. in 3 of the remaining 716 (0.42%) there may have been true failure of antenatal Rh prophylaxis administered at the 28th week. One would have expected this figure to be 12 of 716 if antenatal Rh prophylaxis at 28 weeks' gestation were totally unsuccessful.It is concluded that a single intramuscular injection of Rh immune globulin, 300 mug, is 88% effective in preventing Rh isoimmunization during pregnancy in Rh-negative primigravidas and in multigravidas treated antenatally in all previous pregnancies, and is 75% effective in preventing Rh isoimmunization in Rh-negative multigravidas untreated during previous pregnancies. The majority of failures are due to Rh isoimmunization during pregnancy prior to antenatal prophylaxis at 28 weeks.

    Full Text Available Background: Calcium-antagonists (CA are heterogeneous group of drugs with different efficacy in migraine prophylaxis. Several studies have firmly demonstrated flunarizine (FLU, and verapamil as the proven calcium-antagonists for migraine prophylaxis. Cinnarizine (CIN, is another CA with less complications and less antihistaminic action. There is very few studies to show the effect of this drug on migraine. The current study evaluates the efficacy and safety of cinnarizine on migraine in comparison to sodium valproate, an acceptable drug in migraine prophylaxis. Methods: The current study is a randomized double blind clinical trial on 133 participants with intractable migraine headache to evaluate the positive effect of cinnarizine in comparison to sodium valproate. The data was collected and analized by SPSS software. Results: The mean age of cases was 34.3±10 years in Cinnarizine group and 33.4±11 in Sodium Valproate users. The headache frequency decreased to about 50% and its severity to about 30% in both groups. Although the effect of Cinnarizine was started earlier than sodium valproate , there was no significant difference between two groups of cases in improvement of headache attacks. Statistically significant difference was noted in drug’s complication led to discontinuation of treatment, 5.2% in Cinnarizine users in respect to 14% in valproate group. Conclusion: The patients who received Cinnarizine, similar to the patients on sodium valprote showed significant improvement in headache attacks, frequency, duration and severity. Cinnarizine such as sodium valproate is an effective drug in migraine prophylaxis even in intractable headache, but with lesser severe complication.

    Full Text Available Stephen G Schwartz,1 Andrzej Grzybowski,2 Harry W Flynn Jr1 1Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL, USA; 2Department of Ophthalmology, Poznan City Hospital, Poznan, Poland Abstract: Endophthalmitis remains a rare but important cause of visual loss. Prophylaxis strategies are important to reduce rates of endophthalmitis after cataract surgery, intravitreal injection, and other procedures. There is substantial variability between the US and the rest of the world. During cataract surgery, intracameral antibiotics are commonly used in many nations, especially in Europe, but are less commonly used in the US. A randomized clinical trial from the European Society of Cataract and Refractive Surgeons reported an approximately fivefold reduction in endophthalmitis rates associated with intracameral cefuroxime but these results are controversial. There are no randomized clinical trials regarding endophthalmitis associated with intravitreal injection. Topical antibiotics are commonly used in many nations, but are less commonly used in the US. At this time, there is no global consensus and it appears unlikely that additional major clinical trials will conclusively define the optimal endophthalmitis prophylaxis techniques.

    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.

    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

    Itraconazole is often given for fungal prophylaxis to lung transplant recipients after transplantation. The aim of this study was to determine the extent of interaction between tacrolimus and itraconazole in lung transplant recipients and the efficacy of itraconazole prophylaxis. The study group included 40 lung transplant recipients followed for at least 12 months. All received prophylactic itraconazole, 200 mg twice a day, for the first 6 months after transplantation. Tacrolimus levels and dosage requirements were compared during and after itraconazole therapy. Rejection rate, fungal infection rate, and renal function were assessed. The mean cost per daily treatment of the itraconazole/tacrolimus combination and tacrolimus alone was calculated. The mean tacrolimus dose during itraconazole treatment was 3.26 +/- 2.1 mg/day compared with 5.74 +/- 2.9 mg/day after itraconazole was stopped (p < 0.0001) for a mean total daily dose elevation of tacrolimus of 76%. When the cost of itraconazole was taken into account, the average total daily cost of the combined treatment was US5.86 dollars less than the treatment with tacrolimus alone. No differences in the rejection or fungal infection rate, or in renal toxicity, were observed between the periods with and without itraconazole treatment, although less positive fungal isolates were identified during itraconazole therapy. Prophylaxis therapy with itraconazole is highly effective. Itraconazole reduces the dose of tacrolimus and therefore lowers the cost of therapy without causing an increase in rejection rate and with renal function preservation.

    Full Text Available Abstract Background Cirrhotic patients are characterized by a decreased synthesis of coagulation and anticoagulation factors. The coagulopathy of cirrhotic patients is considered to be auto-anticoagulation. Our aim was to determine the incidence and predictors of venous thromboembolism (VTE and examine the practice of deep venous thrombosis (DVT prophylaxis among hospitalized cirrhotic patients. Methods A retrospective cohort study was performed in a tertiary teaching hospital. We included all adult patients admitted to the hospital with a diagnosis of liver cirrhosis from January 1, 2009 to December 31, 2009. We grouped our cohort patients in two groups, cirrhotic patients without VTE and cirrhotic with VTE. Results Over one year, we included 226 cirrhotic patients, and the characteristics of both groups were similar regarding their clinical and laboratory parameters and their outcomes. Six patients (2.7% developed VTE, and all of the VTEs were DVT. Hepatitis C was the most common (51% underlying cause of liver cirrhosis, followed by hepatitis B (22%; 76% of the cirrhotic patients received neither pharmacological nor mechanical DVT prophylaxis. Conclusion Cirrhotic patients are at risk for developing VTE. The utilization of DVT prophylaxis was suboptimal.

    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.

    Vitamin K prophylaxis prevents hemorrhagic disease of the newborn. The present review estimates the potential magnitude of this problem in less developed countries, assessing the need for prophylaxis, along with its cost-effectiveness and feasibility. Late hemorrhagic disease, occurring between 2 and 12 weeks, often leads to death or permanent disability. Its median incidence in developed countries is 7 per 100,000 births. Incidences in less developed countries may be much higher. Three incidence scenarios are proposed and the corresponding losses of disability-adjusted life-years (DALYs) calculated. Under the intermediate scenario, late hemorrhagic disease accounts for 0.1% to 0.2% of DALYs lost to children less than 5 years of age. Assuming a cost of +1.00 per injection, each DALY saved would cost +133. Decisions on prophylaxis must be made on a national basis, considering mortality levels and causes, health budgets, and feasibility. Comparison with the impact of diseases prevented by breast-feeding shows that concern with hemorrhagic disease should not affect breast-feeding promotion efforts, although strategies for supplementing breast-fed infants must be explored.

    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.

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.

Objectives We prospectively examined the contribution of an antithrombotic prophylaxis in influencing clinical pregnancy and live-birth in an unselected cohort of women approaching ART. Patients/Methods 1107 women with fertility problems and a valid indication for ART were recruited. Baseline and follow-up information of obstetric outcomes and antithrombotic treatment were collected. Results and Conclusions Median follow-up time was 34.5 months (range: 2–143). During the follow-up period, 595 (53.8%) women underwent ART (total 1234 cycles); 202 (33.9%) women achieved a pregnancy for a total of 255 clinical pregnancies. The concomitant use of LMWH and aspirin was significantly associated with a higher rate of clinical pregnancies (p: 0.003, OR: 4.9, 95% CI: 1.7–14.2). The pregnancy rate was also significantly increased by the use of LMWH alone (p: 0.005, OR: 2.6, 95% CI: 1.3–5.0). Carriership of inherited or acquired thrombophilia did not affect clinical outcomes of the ART. The efficacy of antithrombotic treatment was confirmed when the outcome “ live-birth” was considered. Present data suggest a potential benefit of antithrombotic prophylaxis during ART in improving the number of live-births. PMID:24870449

    BACKGROUND:Reversal of liver ifbrosis is one of the key steps in the prevention and treatment of alcoholic liver disease (ALD), but the mechanism is unknown. This study was to investigate the effects of the Chinese medicine Kang Xian Fu Fang Ⅰ (KXⅠ) on prophylaxis and treatment of ALD in rats and its possible mechanism of action. METHODS: Eighty male Wistar rats were randomly divided into four groups: normal control; ALD model;treatment of ALD with KXⅠ; and prophylaxis of ALD by KXⅠ. At the end of 4, 8, 12 and 16 weeks, ifve rats from each group were anesthetized and their livers were removed for pathological studies using hematoxylin-eosin and Masson stain, immunohistochemical studies, and lfow cytometry for matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9). Blood samples were taken for hyaluronic acid (HA) assay. RESULTS: Serum HA level and liver collagen content were lower in the groups given KXⅠfor prophylaxis and treatment than in ALD model group (P CONCLUSIONS:KXⅠcan effectively inhibit or reverse the course of ALD. This may be attributable to its capacity to inhibit the expression of MMP-2 and MMP-9.

    Full Text Available We retrospectively evaluated the efficacy of prophylaxis with pipemidic acid and levofloxacin in transrectal ultrasound guided prostate biopsy (TRUSP-Bx. From January 2002 to December 2004, patients receiving oral pipemidic acid 500 mg twice daily for three days with or without a preoperative intravenous cefazolin 1 gm injection comprised group A. Between January 2005 and December 2009, patients receiving oral levofloxacin 500 mg one hour before biopsy comprised group B. We calculated the annual febrile urinary tract infection (fUTI rates. Patients’ characteristics, including age, prophylactic antibiotics, biopsy core numbers, pathologic results, PSA, and the spectrums and susceptibility of pathogens, were also evaluated. A total of 1313 (35.5% patients belonged to group A, while 2381 (64.5% patients belonged to group B. Seventy-three patients experienced postoperative infectious complications. There was a significant difference in the fUTI rate between groups A and B (3.7% versus 1.0%, P<0.001. The yearly fUTI rates varied from 0.6 to 3.9% between 2002 and 2009. Of the 73 patients with fUTI, those receiving levofloxacin prophylaxis were more likely to harbor fluoroquinolone-resistant pathogens (P<0.001. E. coli was the most common pathogen in both groups. Levofloxacin remains effective and appears superior to pipemidic acid based prophylaxis.

    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

    Full Text Available Background: Venous thromboembolism (VTE is a major cause of mortality among cancer patients. The aim of this study was to evaluate drug regimens used for the prophylaxis of thromboembolic events in cancer patients.Methods: A retrospective study was conducted using medical records of patients hospitalized from March 2012 to March 2014 at Cancer Division of A tertiary university-affiliated hospital in North of Iran. The risk factors of patients regarding need of venous thromboembolic (VTE prophylaxis were recognized and dosage and duration of thromboembolic prophylactic agents were evaluated according to the National Comprehensive Cancer Network (NCCN 2012 guidelines. Statistical analysis was performed using SPSS v.23.Results: Of a total of 1160 medical records, VTE prophylaxis regimens of 186 patients were evaluated. In 18(13.1% and 15(10.9% of patients, administrations were compatible with NCCN guidelines with respect to the "type of drug" and "dosage", respectively. Only in 7(5.1% of patients administrations were compatible with respect to the "duration of thromboembolic prophylaxis regimen". Forty patients (21.7% had relative contraindication for thromboembolic prophylaxis and 7(3.8% patients had absolute contraindication. In 32(80% of 40 patients with relative contraindications and only in 1(14.3% of 7 patients with absolute contraindications, physicians’ orders were compatible with NCCN guidelines.Conclusion: The rate of concordance of the VTE prophylaxis with recommendations provided by NCCN is very poor. This study emphasizes need of a multidisciplinary action to improve the VTE prophylaxis in cancer patients.

    Rigorous evidence is lacking on long-term outcomes of factor VIII (FVIII) prophylaxis initiated in adolescent or adult patients with severe haemophilia A. The prospective, open-label Prophylaxis versus On-demand Therapy Through Economic Report (POTTER) study (ClinicalTrials.gov NCT01159587) compared long-term late secondary prophylaxis (recombinant FVIII-FS 20-30 IU/kg thrice weekly) with on-demand treatment in patients aged 12 to 55 years with severe haemophilia A. The annual number of joint bleeding episodes (primary endpoint), total bleeding episodes, orthopaedic and radiologic (Pettersson) scores, health-related quality of life (HRQoL), pharmacoeconomic impact, and safety were evaluated over a > 5-year period (2004-2010). Fifty-eight patients were enrolled at 11 centres in Italy; 53 (27 prophylaxis, 26 on demand) were evaluated and stratified into 2 age subgroups (12-25 and 26-55 years). Patients receiving prophylaxis experienced a significantly lower number of joint bleeding episodes vs the on-demand group (annualised bleeding rate, 1.97 vs 16.80 and 2.46 vs 16.71 in younger and older patients, respectively; p=0.0043). Results were similar for total bleeding episodes. Prophylaxis was associated with significantly fewer target joints (pPOTTER study is the first prospective, controlled trial documenting long-term benefits of late secondary prophylaxis in adolescents and adults with severe haemophilia A. The benefits of reduced bleeding frequency, improved joint status, and HRQoL may offset the higher FVIII consumption and costs.

    Patients undergoing intensive chemotherapy for acute myeloid leukemia are at high risk for bacterial infections during therapy-related neutropenia. However, the use of specific antibiotic regimens for prophylaxis in afebrile neutropenic acute myeloid leukemia patients is controversial. We report a retrospective evaluation of 172 acute myeloid leukemia patients who received 322 courses of myelosuppressive chemotherapy and had an expected duration of neutropenia of more than seven days. The patients were allocated to antibiotic prophylaxis groups and treated with colistin or ciprofloxacin through 2 different hematologic services at our hospital, as available. The infection rate was reduced from 88.6% to 74.2% through antibiotic prophylaxis (vs. without prophylaxis; P=0.04). A comparison of both antibiotic drugs revealed a trend towards fewer infections associated with ciprofloxacin prophylaxis (69.2% vs. 79.5% in the colistin group; P=0.07), as determined by univariate analysis. This result was confirmed through multivariate analysis (OR: 0.475, 95%CI: 0.236–0.958; P=0.041). The prophylactic agents did not differ with regard to the microbiological findings (P=0.6, not significant). Of note, the use of ciprofloxacin was significantly associated with an increased rate of infections with pathogens that are resistant to the antibiotic used for prophylaxis (79.5% vs. 9.5% in the colistin group; P<0.0001). The risk factors for higher infection rates were the presence of a central venous catheter (P<0.0001), mucositis grade III/IV (P=0.0039), and induction/relapse courses (vs. consolidation; P<0.0001). In conclusion, ciprofloxacin prophylaxis appears to be of particular benefit during induction and relapse chemotherapy for acute myeloid leukemia. To prevent and control drug resistance, it may be safely replaced by colistin during consolidation cycles of acute myeloid leukemia therapy. PMID:27470601

    Full Text Available Background: Antibiotic prophylaxis is an effective tool to reduce surgical infection rates. However, antibiotic prophylaxis in cholecystectomy is controversial when non-high risk patients are considered. This research aims to evaluate the adherence with antibiotic prophylaxis protocol in patients undergoing cholecystectomy, and its impact in the outcomes of surgical infection. Methods: This single-center observational and retrospective study analyzed all elective cholecystectomy procedures carried out at the Fundación Alcorcón University Hospital in the period 2007-2014. Data were recovered from hospital records; rates of adherence to the available hospital protocols were evaluated for choice, initiation, duration, administration route and dosages of antibiotics, and the starting and duration of the prophylaxis. Results: The overall adequacy rate to protocol was 72%. The adherence rates in both the administration route and dose were 100%. The most common violations of the protocol included the choice of antibiotic agent (19%, followed by the moment of initiating its administration (8.9%. The overall wound infection rate was lower in case of laparoscopy than in laparotomy cholecystectomy (1.4% vs. 4.3%, p < 0.05; odds rate [OR] 0.29, 95% confidence interval [CI] 0.1-0.6. No relationship between adequacy of antibiotic prophylaxis and surgical infection rate was documented, neither considering overall gallbladder surgeries (crude OR 0.26, 95% CI 0.1-2.0, nor laparoscopy vs. open surgery (MH adjusted OR 0.24, 95% CI 0.2-2.1. Conclusions: The overall adequacy rate to antibiotic prophylaxis protocol recommended for elective cholecystectomy in our hospital was high (72%. No significant association between the adequacy or antibiotic prophylaxis and surgical infection was found.

    Full Text Available Aims and Objectives: To study the compliance of patients of Rheumatic fever (RF/ Rheumatic heart disease (RHD regarding secondary prophylaxis with injection benzathine penicillin. Materials and Methods: The study was conducted in the Pediatric Rheumatology Outpatients’ Department (OPD of a tertiary care teaching university affiliated hospital. Patients below 18 years of age diagnosed as Rheumatic fever/ Rheumatic heart disease following up in Pediatric Rheumatology OPD for at least 1 year for benzathine pencillin prophylaxis were included in the study. The patients diagnosed to have RF/ RHD were advised injection benzathine penicillin prophylaxis every 3 weeks. A proforma was devised for recording the clinical details of the patient- including demographic information, clinical details regarding RF/ RHD and rheumatic fever recurrences. The details of the benzathine penicillin prophylaxis taken by the patient were also recorded in the proforma. The reasons for non-compliance were noted and enlisted as per their frequency. Results: The study included 10 patients following up at the specialty clinic for rheumatic heart disease patients. We had 7 males and 3 females in the study. The average age was 9.7 yrs (6 years to 12 years. The average number of months of follow up for assessing the compliance was 20.7 months (12.6 months to 44 months. The average compliance (% of the 10 patients was 89.60% (63.69% to 100%. Out of the 10 subjects, four had a recurrence of rheumatic fever manifesting in the form of congestive cardiac failure & carditis. Though most of the times the patients were not able to recall the reason for missing the dose, trip to one’s native place was an important reason for missed doses besides forgetting the dates of the prophylaxis and doubts about need for the prophylaxis. Conclusions: Compliance of secondary prophylaxis with benzathine penicillin was about 90% in the present study. Frequent travel by patients to their native

    Full Text Available Abstract Background Myelosuppressive chemotherapy can lead to dose-limiting febrile neutropenia. Prophylactic use of recombinant human G-CSF such as daily filgrastim and once-per-cycle pegfilgrastim may reduce the incidence of febrile neutropenia. This comparative study examined the effect of pegfilgrastim versus daily filgrastim on the risk of hospitalization. Methods This retrospective United States claims analysis utilized 2004–2009 data for filgrastim- and pegfilgrastim-treated patients receiving chemotherapy for non-Hodgkin’s lymphoma (NHL or breast, lung, ovarian, or colorectal cancers. Cycles in which pegfilgrastim or filgrastim was administered within 5 days from initiation of chemotherapy (considered to represent prophylaxis were pooled for analysis. Neutropenia-related hospitalization and other healthcare encounters were defined with a “narrow” criterion for claims with an ICD-9 code for neutropenia and with a “broad” criterion for claims with an ICD-9 code for neutropenia, fever, or infection. Odds ratios (OR for hospitalization and 95% confidence intervals (CI were estimated by generalized estimating equation (GEE models and adjusted for patient, tumor, and treatment characteristics. Per-cycle healthcare utilization and costs were examined for cycles with pegfilgrastim or filgrastim prophylaxis. Results We identified 3,535 patients receiving G-CSF prophylaxis, representing 12,056 chemotherapy cycles (11,683 pegfilgrastim, 373 filgrastim. The mean duration of filgrastim prophylaxis in the sample was 4.8 days. The mean duration of pegfilgrastim prophylaxis in the sample was 1.0 day, consistent with the recommended dosage of pegfilgrastim - a single injection once per chemotherapy cycle. Cycles with prophylactic pegfilgrastim were associated with a decreased risk of neutropenia-related hospitalization (narrow definition: OR = 0.43, 95% CI: 0.16–1.13; broad definition: OR = 0.38, 95% CI: 0.24–0.59 and all

    Full Text Available Background. Evidence-based data on optimal approach for prophylaxis of deep venous thrombosis (VTE and pulmonary embolism (PE in bariatric operations is discussed. Using antithrombotic prophylaxis weight adjusted the risk of VTE and its complications have to be balanced with the increased bleeding risk. Methods. Since 2005 the current situation for bariatric surgery has been examined by quality assurance study in Germany. As a prospective multicenter observational study, data on the type, regimen, and time course of VTE prophylaxis were documented. The incidences of clinically diagnosed VTE or PE were derived during the in-hospital course and follow up. Results. Overall, 11,835 bariatric procedures were performed between January 2005 and December 2010. Most performed procedures were 2730 gastric banding (GB; 4901 Roux-en-Y-gastric bypass (RYGBP procedures, and 3026 sleeve gastrectomies (SG. Study collective includes 72.5% (mean BMI 48.1 kg/m2 female and 27.5% (mean BMI 50.5 kg/m2 male patients. Incidence of VTE was 0.06% and of PE 0.08%. Conclusion. VTE prophylaxis regimen depends on BMI and the type of procedure. Despite the low incidence of VTE and PE there is a lack of evidence. Therefore, prospective randomized studies are necessary to determine the optimal VTE prophylaxis for bariatric surgical patients.

    Full Text Available Objectives. To assess the standard practice of care of surgeons regarding surgical antibiotic prophylaxis, to identify gaps, and to set recommendations. Methods. A retrospective analysis of data obtained from different surgical units in a single center in Qatar over a 3-month period in 2012. A total of 101 patients who underwent surgery and followed regimes for surgical prophylaxis as per hospital guidelines were included in the study. Results. The overall use of antibiotic was 89%, whereas the current practice did not match the recommended hospital protocols in 53.5% of cases. Prolonged antibiotics use (59.3% was the commonest reason for nonadherence followed by the use of an alternative antibiotic to that recommended in the protocol (31.5% and no prophylaxis was used in 9.2% of cases. The rate of compliance was significantly higher among clean surgery than clean contaminated group (P=0.03. Forty-four percent of clean and 65% of clean-contaminated procedures showed noncompliance with the recommended surgical antimicrobial prophylaxis hospital guidelines. Conclusion. Lack of adherence to hospital protocols is not uncommon. This finding remains a challenge to encourage clinicians to follow hospital guidelines appropriately and to consistently apply the surgical antibiotic prophylaxis. The role of clinical pharmacist may facilitate this process across all surgical disciplines.

    Because of the very short half-life of factor VII, prophylaxis in factor VII deficiency is considered a difficult endeavor. The clinical efficacy and safety of prophylactic regimens, and indications for their use, were evaluated in factor VII-deficient patients in the Seven Treatment Evaluation Registry. Prophylaxis data (38 courses) were analyzed from 34 patients with severe factor VII deficiency (plasma-derived factor VII, and ten received fresh frozen plasma. Prophylactic schedules clustered into "frequent" courses (three times weekly, n=23) and "infrequent" courses (≤ 2 times weekly, n=15). Excluding courses for menorrhagia, "frequent" and "infrequent" courses produced 18/23 (78%) and 5/12 (41%) "excellent" outcomes, respectively; relative risk, 1.88; 95% confidence interval, 0.93-3.79; P=0.079. Long term prophylaxis lasted from 1 to >10 years. No thrombosis or new inhibitors occurred. In conclusion, a subset of patients with factor VII deficiency needed prophylaxis because of severe bleeding. Recombinant activated factor VII schedules based on "frequent" administrations (three times weekly) and a 90 μg/kg total weekly dose were effective. These data provide a rationale for long-term, safe prophylaxis in factor VII deficiency.

    Prophylactic infusion of clotting factor concentrates is a developing standard of care for individuals with haemophilia. The ideal schedule and techniques of prophylactic infusions remain incompletely defined. Our aim was to determine the optimal techniques and schedules for factor prophylaxis in paediatric patients. A retrospective electronic medical record review of all children treated with prophylactic factor infusions in a single Haemophilia Treatment Center was conducted. Comparison of traditional vs. Canadian dosing regimens and primary vs. secondary prophylaxis was made. Failure of prophylaxis was defined as the first serious bleed. A total of 58 children were identified for review. Five cases were excluded (four due to high titre inhibitors and one due to repeated non-compliance), thus there were 53 total cases: 46 with severe haemophilia, 2 with moderate haemophilia, 5 with mild haemophilia, 44 with haemophilia A and 9 with haemophilia B; 32 Traditional dosing and 21 Canadian dosing regimens. Patients on primary prophylaxis had a decreased failure rate (25%) compared to children treated with secondary prophylaxis (67%) regardless of technique of prophylaxis. When compared to a 'Traditional' factor prophylaxis schedule, the 'Canadian' tailored prophylaxis protocol was comparable with the exception of a decreased use of implanted venous devices in the 'Canadian' group. Ongoing bleeding (primarily joint bleeds) occurs with all prophylactic regimens. The lowest incidence of treatment failure was noted in children who began primary prophylaxis at a young age and before initial joint bleeds. Primary prophylaxis is superior to secondary prophylaxis regardless of dosing regimen. Traditional and Canadian dosing regimens were equivalent in outcome when measured over several years of follow-up.

    Full Text Available Objective: To evaluate the clinical impact of the prophylactic treatment with sublingual immunostimulation in the prevention of recurrent urinary tract infections (rUTIs compared with the use of antibiotics.Material and Methods: Retrospective cohort study evaluating the clinical records of 669 women with rUTIs; 339 had a 6-month prophylaxis with antibiotics and 360 had a 3-month prophylaxis with a sublingual bacterial preparation (MV 140-Uromune®. The time after the prophylaxis-period until the appearance of a new infection (assessed by uroculture was scored during one year. Absolute risk reduction (ARR and number needed to treat (NNT were also calculated.Results: All patients (100% treated with antibiotics experienced a new UTI during the scoring period of 12 months, being the mean time free of UTI 29 (±38 days. In the group treated with the bacterial preparation, only 35 (9.7% patients experienced UTI in the same period. Kaplan-Meier curves comparing the accumulated survival (disease-free time between both groups were significant (P < 0.0001. ARR was 90.28 % (87.18-93.38 and NNT 1.1 (1.1-1.1.Conclusions: These results suggest that the treatment with the bacterial preparation reduces rUTIs very effectively, arising as an effective strategy to reduce the frequency of rUTIs. It reduces antibiotic consumption, matching the current recommendations due to the raise of antimicrobial resistance. Randomized, double-blind and placebo-controlled, clinical trials are needed to establish more accurately the clinical impact of this bacterial preparation in patients with rUTIs.

    Recurrent herpes simplex keratitis (HSK) is a leading infectious cause of blindness in industrialized countries. Antiviral prophylaxis (AVP) may fail to prevent recurrence of HSK due to viral resistance, inadequate dosing, or poor patient compliance. In this prospective multicenter study, we enrolled immunocompetent patients with recurrent HSK despite AVP. Ocular samples were tested by PCR for herpes simplex virus 1 (HSV-1). HSV-1 drug resistance was assessed with a genotypic assay based on UL23 and UL30 gene sequencing. After curative full dose valacyclovir (VACV) treatment was started, peak and trough acyclovir (ACV) plasma concentrations were measured, and patient compliance to AVP was assessed with a questionnaire. The study sample was comprised of 43 patients. Six (14%) patients were positive for HSV-1 using PCR, of whom 5 (83%) harbored genotypically ACV-resistant (ACV(R)) virus, due to mutations in UL23 (n = 4) or UL30 (n = 1). Disease duration was statistically significantly longer in patients with viral resistance compared to other HSK patients [35.5 ± 23.4 years (range, 6.8-68.4 years) versus 11.1 ± 12.3 years (range, 0.8-56.3 year) respectively; Mann-Whitney p = 0.01)]. While patients were treated with full dose VACV, trough ACV plasma concentrations were below the threshold for ACV sensitivity in 9.5% of cases, and compliance was poor in 5.3% of cases. To summarize, HSV-1 resistance to ACV seems to be a significant cause of failure of prophylaxis in patients with HSK and is associated with longer disease duration. Most PCR-positive samples contained genotypically ACV(R) virus and identification may aid in adapting treatment. Incomplete 24-h drug coverage may also explain some cases of failure of prophylaxis.

    Full Text Available Childhood blindness due to corneal ulceration was prevalent among poor Indian children. To tackle this situation, the National Institute of Nutrition (NIN, Hyderabad, India, Vitamin-A (Vit-A prophylaxis programme was launched nationally in 1970 after field testing. Research of Indian Council for Medical Research (ICMR documented that prevalence of Vit-A deficiency signs such as Bitot’s spot decreased among children, over a period of time. However, this decrease cannot be ascertained is due to mass Vit-A prophylaxis programme. This is because coverage was low and patchy. Improved nutrition status, wider vaccination coverage, increased rate in breast feeding and improvement of healthcare services played a crucial role. Rather many studies revealed that (mass prophylaxis to the child who is having adequate Vit-A level it may be harmful to certain group of children as a result of acute toxic symptoms. High dose of Vit-A is capable of loss of bone density-hence retarded growth may be observed in susceptible individuals. To tackle this issue food based approach should be promoted (which includes breast feeding along with timely measles vaccination. The children who have signs of Vit-A deficiency (e.g. night blindness, xeropthalmia, Bitot’s spot or post measles children should receive Vit-A in age specific daily doses for two weeks along with Vit-A rich food, like green leafy vegetables, red palm oil, liver etc. Public spirited citizens, together with scientific community in India, should discourage this “one size fit to all” approach. It will not only avoid the ill effects of high dose of Vit-A but also it will help us optimal utilization of health resources in a resource poor country like India.

    Full Text Available Introduction: A review was undertaken for a consecutive series of hip fracture patients for the year before and then after a change in low dose heparin prophylaxis policy. Patients and methods: For the first year heparin was administered in hospital for a maximum of 14 days only. Patients sent home before this time were not discharged taking heparin. For the second year heparin was administered as recommended by NICE guidelines for 28 days from admission regardless of whether the patient was discharged. Results: For the first year 486 patients were treated with a mean of 10.4 doses of heparin per patient. For the second year 465 patients were treated with a mean of 24.3 doses per patient. In total an extra 6,464 doses of heparin were administered. 33.8% of patients were unable to administer their heparin at home therefore a district nurse administered 2,284 of these doses of subcutaneous heparin at the patient’s home. The increased cost associated with the change in policy was estimated to be £161 per patient, with over 90% of this increase being incurred by the district nurse expense. If applied nationally for the England, using extended heparin prophylaxis for hip fracture patients would cost in excess of 12 million pounds each year. Conclusion: Whilst the necessity for and duration of thromboembolic prophylaxis for these patients remains undetermined, there is a need to re-evaluate the cost effectiveness of the current recommendations for hip fracture patients.

    Full Text Available Background: The emergence of resistance has been demonstrated in cancer treatment centers where prophylaxis with fluoroquinolone is used. Objective: Considering the importance of epidemiological monitoring as a strategy in choosing protocols involving antibiotics, this study aimed to evaluate the emergence of quinolone resistance and changes in the local epidemiology in a hematopoietic stem cell transplant service. Methods: For this study, 60 positive cultures before the prophylactic use of levofloxacin (period A: 2007-2008 and 118 cultures after starting the use of prophylactic levofloxacin (period B: 2010-2011 were evaluated. Results: Resistance increased for all the different types of bacteria isolated (from 46.0% to 76.5%; p-value = 0.0002. Among Gram-negative bacteria, resistance increased from 21.4% to 60.7% (p-value = 0.0163 and among Gram-positive bacteria, it increased from 55.6% to 82.9% (p-value = 0.0025. The use of levofloxacin increased from 19.44 defined daily doses per 1,000 patient-days in period A to 166.64 in period B. The use of broad spectrum antibiotics remained unchanged. Considering bacteria associated with infection, 72 and 76 were isolated in periods A and B, respectively. There was a reduction in the rate of Gramnegative bacteria in cultures associated with infection (3.81 vs. 2.00 cultures/1,000 patientdays; p-value = 0.008. Conclusion: The study of prophylaxis with levofloxacin demonstrated that there was a decrease in infections by Gram-negative bacteria; however, bacterial resistance increased, even though the use of broad-spectrum antibiotics remained unchanged. Constant monitoring of local epidemiology combined with research on clinical outcomes is needed to evaluate the effectiveness of prophylaxis.

    Hospital-Acquired venous thromboembolism (VTE) is a common cause of morbidity and mortality in older adults. In psychiatric patients these risks are increased due to multiple factors including poor mobility, restraint, catatonia, sedation, and conventional antipsychotic use. Diagnosis and treatment of psychiatric patients presenting with signs and symptoms of a VTE can be delayed due to a patient's communication difficulties, non-compliance, or attribution of symptoms to a psychosomatic cause. However, despite the increased risk, approved VTE prophylaxis protocols are infrequently used on Psychiatric wards. On one Older Adult Psychiatric Ward, two patients presented with VTE (a fatal pulmonary embolism and a symptomatic deep vein thrombosis) over a 6 month period demonstrating the necessity for prophylactic assessment. A baseline audit over 3 months showed that 63-83% of patients on the ward had received no assessment of VTE risk, on any given week, although this improved slightly following the critical incidents. A VTE prophylaxis protocol, based on NICE guidance for VTE risk assessment in Medical and Surgical patients, was developed with consideration given to additional Psychiatric risk factors. This took the form of a pro-forma with a tick-box design that included mobility assessment, VTE risk factors, bleeding risk factors, and guidance on prescribing decisions. This was implemented on an Older Adult Psychiatric ward and prophylaxis was provided to those meeting the threshold. Weekly audit of all pro-formas (including assessments completed within 48 hours of admission and prophylaxis prescription) was conducted after the pro-forma introduction from 1st February 2013 to 24th May 2013. Frequency of assessments increased after protocol implementation with between 36% and 85% of all patients being assessed for VTE risk post intervention. Fluctuations in numbers assessed may have related to ward pressures, staff changes, and practicalities of pro-forma use. After

    Full Text Available Infections are still an important cause of mortality and morbidity in pediatric cancer patients. Most of the febrile episodes in immunocompromised patients are classified as a fever of unknown origin (FUO while bacteria are the more frequent causes of documented infections. Viral infections are also feared during chemotherapy but less data are available on their incidence and morbidity. We reviewed the literature on incidence, morbidity, and mortality of viral infections in children undergoing chemotherapy and discussed the evidence concerning the prophylaxis and the therapy.

    Heparin prophylaxis (HP) is commonly used for prevention of central venous catheter (CVC)-related complications among pediatric intensivists, yet efficacy of this therapy is unknown. We conducted a survey of pediatric intensivists and their experiences with HP. A total of 96 responses were received. Almost half of the respondents regularly used HP in patients with CVCs, yet most were unsure of its benefit. The majority of respondents claimed to experience no adverse effects; the complications that were reported to occur were related to bleeding or suspected heparin-induced thrombocytopenia (HIT). Overall, participants felt CVC-associated HP was safe in pediatric critical illness, while acknowledging the paucity of compelling data.

    @@ TO THE EDITOR More than 80% of cirrhotic patients who have been treated successfully for spontaneous bacterial peritonitis (SBP)experience a recurrence[1,2]. Long-term prophylaxis with single daily oral antibiotic has been shown to be cost effective in delaying a recurrence but only for a short time[3].What has never been tested in this population is the cycling of antibiotics. We report the beneficial use of antibiotic cycling for 36 weeks in a 74-year-old woman with cryptogenic cirrhosis and recurrent SBP.

    During the 2004 cholera outbreak in Douala, densely populated and poor suburban populations had very poor access to safe drinking water and were at high risk of transmission. The provincial task force thus decided to provide preventive antibiotic treatment of all patient contacts, that is, family members taking care of patients in the hospital and household members of patients or close neighbours living in houses directly adjacent to patients. This retrospective report, based on data from hospitals, local cholera committees, and pharmacies, describes the course of the epidemic, bacteriological monitoring, and antibiotic distribution. Suddenly appearing in January 2004, the outbreak affected 5,020 patients in 8 months. V.cholera
