    With a global estimate of 2.5 million new infections of HIV occurring yearly, discovering novel methods to help stem the spread of the virus is critical. The use of antiretroviral chemoprophylaxis for preventing HIV after accidental or occupational exposure and in maternal to fetal transmission has become a widely accepted method to combat HIV. Based on this success, pre-exposure chemoprophylaxis (PrEP) is being explored in at-risk patient populations such as injecting drug users, female sex workers and men who have sex with men. This off-label and unmonitored use has created a need for education and intervention by pharmacists and other healthcare professionals. Pharmacists should educate themselves on PrEP and be prepared to counsel patients about their means of obtaining it (e.g. borrowing or sharing medications and ordering from disreputable Internet pharmacies). They should also be proactive about medication therapy management in these patients due to clinically important drug interactions with PrEP medications. Only one trial exploring the safety and efficacy of tenofovir as PrEP has been completed thus far. However, five ongoing trials are in various stages and two additional studies are scheduled for the near future. Unfortunately, studies in this arena have met with many challenges that have threatened to derail progress. Ethical controversy surrounding post-trial care of participants who seroconvert during studies, as well as concerns over emerging viral resistance and logistical site problems, have already halted several PrEP trials. Information about these early trials has already filtered down to affected individuals who are experimenting with this unproven therapy as an "evening before pill". The potential for PrEP is promising; however, more extensive trials are necessary to establish its safety and efficacy. Pharmacists are well-positioned to play a key role in helping patients make choices about PrEP, managing their therapy, and developing policy

  4. Combination chemoprophylaxis and immunoprophylaxis in reducing the incidence of leprosy.

    Leprosy is a complex infectious disease caused by Mycobacterium leprae that is a leading cause of nontraumatic peripheral neuropathy. Current control strategies, with a goal of early diagnosis and treatment in the form of multidrug therapy, have maintained new case reports at ~225,000 per year. Diagnostic capabilities are limited and even with revisions to multidrug therapy regimen, treatment can still require up to a year of daily drug intake. Although alternate chemotherapies or adjunct immune therapies that could provide shorter or simpler treatment regimen appear possible, only a limited number of trials have been conducted. More proactive strategies appear necessary in the drive to elimination. As a prevention strategy, most chemoprophylaxis campaigns to date have provided about a 2-year protective window. Vaccination, in the form of a single bacillus Calmette-Guérin (BCG) immunization, generally provides ~50% reduction in leprosy cases. Adapting control strategies to provide both chemoprophylaxis and immunoprophylaxis has distinct appeal, with chemoprophylaxis theoretically buttressed by vaccination to generate immediate protection that can be sustained in the long term. We also discuss simple assays measuring biomarkers as surrogates for disease development or replacements for invasive, but not particularly sensitive, direct measures of M. leprae infection. Such assays could facilitate the clinical trials required to develop these new chemoprophylaxis, immunoprophylaxis strategies, and transition into wider use. PMID:27175099

    Full Text Available Abstract Background Acute malaria has been associated with a decreased antibody response to tetanus and diphtheria toxoids, meningococcal, salmonella, and Hib vaccines. Interest in giving malaria drug therapy and prevention at the time of childhood immunizations has increased greatly following recent trials of intermittent preventive therapy during infancy (IPTi, stimulating this re-analysis of unpublished data. The effect of malaria chemoprophylaxis on vaccine response was studied following administration of measles vaccines and diphtheria-tetanus-whole cell pertussis (DTP vaccines. Methods In 1975, six villages divided into two groups of children ≤74 months of age from Burkina Faso, were assigned to receive amodiaquine hydrochloride chemoprophylaxis (CH+ every two weeks for seven months or no chemoprophylaxis (CH-. After five months, children in each group received either one dose of measles or two doses of DTP vaccines. Results For recipients of the measles vaccine, the seroconversion rates in CH+ and CH- children, respectively, were 93% and 96% (P > 0.05. The seroresponse rates in CH+ and CH- children respectively, were 73% and 86% for diphtheria (P > 0.05 and 77% and 91% for tetanus toxoid (P > 0.05. In a subset analysis, in which only children who strictly adhered to chemoprophylaxis criteria were included, there were, likewise, no significant differences in seroconversion or seroresponse for measles, diphtheria, or tetanus vaccines (P > 0.05. While analysis for pertussis showed a 43% (CH+ and 67% (CH- response (P Conclusion Malaria chemoprophylaxis prior to vaccination in malaria endemic settings did not improve or impair immunogenicity of DTP and measles vaccines. This is the first human study to look at the association between malaria chemoprophylaxis and the serologic response to whole-cell pertussis vaccine.

    repellents and impregnated protective clothing. Secondly, when the stay in malaria-endemic areas is less than 1 week, the disease will appear after returning home. No chemoprophylaxis is needed during the journey. With the onset of fever, diagnosis and therapy are performed without delay at home. This strategy assumes the participation of an informed physician. A third strategy is standby treatment, which is defined by the World Health Organization (WHO) as the use of antimalarial drugs carried for self administration when fever occurs and prompt medical attention is not available. Standby treatment is a safe option for an informed tourist traveling to areas at low risk of malaria or in areas where chemoprophylaxis may not be effective. Likewise, self therapy might be preferred for travelers who make frequent journeys characterized by brief and successive visits to malarious and nonmalarious areas, and for long-term travelers, and expatriots. Standby treatment minimizes drug overuse, demands early investigation of any febrile illness, and insists that effective treatment is given rapidly for P. falciparum malaria that occurs in nonimmune persons. This strategy is the responsibility assumed by teaching physicians and appears to be more advantageous than classic long-term chemoprophylaxis. A fourth strategy is systematic curative treatment carried out under supervision upon a traveler's return home. The administration of halofantrine after departure from endemic areas was studied for the prevention of P. falciparum malaria after short-term exposure,4 but the adverse cardiac effects of this drug obviates the usefulness of this "radical cure". Possibly the administration of doxycycline or azithromycin after departure from malarious areas could prevent P. falciparum malaria after short-term exposure and with less deleterious side effects. This approach requires more research, and again this will be the responsibility of physicians. PMID:9815351

    The outlook of inflammatory joint diseases has changed significantly with the advent of TNF blockers. However, these advances come with a trade off-risk of infections, especially tuberculosis. The Irish society of rheumatology has proposed guidelines to investigate and treat latent TB infection (LTBI), which is in accordance with majority of international recommendations. This protocol requires that every patient with LTBI should have chemoprophylaxis. INH and different anti-rheumatic drugs are known to cause hepatic and gastrointestinal complications. We sought to investigate the toxicity of adding prophylactic anti-TB medications to different DMARDs and anti-TNF agents. We prospectively documented the course of all patients who were prescribed chemoprophylaxis for LTBI, from August 2007 to August 2008. Arrangements were made for central re-issuing of prescription of INH or rifampicin, after reviewing monthly liver function tests and following telephone interview seeking presence of adverse events. Out of 132 patients who were commenced on different TNF blockers, only 23 patients (17%) were diagnosed with LTBI and were given prophylaxis as per recommended guidelines. Thirty-nine percent (9 out of 23) of patients discontinued INH because of adverse events. Primary reason for discontinuation in these 9 patients was as follows: 3 patients got marked transaminitis (transaminases >5 times the normal limit), 5 patients had non-resolving gastrointestinal intolerance (mainly nausea), and one patient developed non-resolving rash. We have found a significant number of our patients (39%) who could not continue anti-TB prophylaxis due to either gastrointestinal intolerance or hypertransaminesemia.

    Actual problems of organization and performance of chemoprophylaxis and chemotherapy of surgical opportunistic infections are discussed with an account of the main principles of and new approaches to the use of antibacterial drugs. The analysis of the authors' observations showed that the pre- and postoperative use of parenteral antibacterial drugs such as cephalosporins (cefazolin and ceftriaxone) and their combinations with aminoglycosides, the simultaneous use of beta-lactams and lysozyme, the local application of new ointments based on polyethylenglycol, foaming agents and gentacycol were prophylactically efficient in patients with high risk of surgical infections. Endolymphatic administration of gentamicin and cefotaxime was highly efficient in the treatment and prophylaxis of severe surgical infections with lymphogenous dissemination of the pathogen or its risk. In the prophylaxis of endogenous infections special attention should be paid to the suppression of the opportunistic intestinal microflora by the use of fluorquinolones and selective decontamination followed by the correction of the intestinal microbiocenosis with probiotics (bifidobacteria), lysozyme and immunological lactoglobulins as dosage forms or dry milk biologically active additives to children diet and dietotherapy.

  13. Review: Malaria chemoprophylaxis for travelers to Latin America.

    2011-12-01

    Because of recent declining malaria transmission in Latin America, some authorities have recommended against chemoprophylaxis for most travelers to this region. However, the predominant parasite species in Latin America, Plasmodium vivax, can form hypnozoites sequestered in the liver, causing malaria relapses. Additionally, new evidence shows the potential severity of vivax infections, warranting continued consideration of prophylaxis for travel to Latin America. Individualized travel risk assessments are recommended and should consider travel locations, type, length, and season, as well as probability of itinerary changes. Travel recommendations might include no precautions, mosquito avoidance only, or mosquito avoidance and chemoprophylaxis. There are a range of good options for chemoprophylaxis in Latin America, including atovaquone-proguanil, doxycycline, mefloquine, and--in selected areas--chloroquine. Primaquine should be strongly considered for nonpregnant, G6PD-nondeficient patients traveling to vivax-endemic areas of Latin America, and it has the added benefit of being the only drug to protect against malaria relapses.

    Since its introduction to the market in 1985, mefloquine has been used for malaria chemoprophylaxis by more than 35 million travellers. In Europe, in 2014, the European Medicines Agency (EMA) issued recommendations on strengthened warnings, prescribing checklists and updates to the product information of mefloquine. Some malaria prevention advisors question the scientific basis for the restrictions and suggest that this cost-effective, anti-malarial drug will be displaced as a first-line anti-malaria medication with the result that vulnerable groups such as VFR and long-term travellers, pregnant travellers and young children are left without a suitable alternative chemoprophylaxis. This commentary looks at the current position of mefloquine prescribing and the rationale of the new EMA recommendations and restrictions. It also describes the new recommendations for malaria prophylaxis that have been adapted by Switzerland, Germany, Austria and Italy where chemoprophylaxis use is restricted to high-risk malaria-endemic areas.

    Pre-exposure prophylaxis (PrEP) for HIV-uninfected persons is highly efficacious for HIV prevention. Understanding how people at risk for HIV will use PrEP is important to inform PrEP scale-up and implementation. We used qualitative methods to gather insights into couples' early experiences with PrEP use within the Partners Demonstration Project, an open-label implementation study evaluating integrated delivery of PrEP and antiretroviral therapy (ART). PrEP is offered to HIV uninfected partners until the HIV-infected partner initiates and sustains ART use (i.e., PrEP as a "bridge" to ART initiation and viral suppression). From August 2013 to March 2014 we conducted 20 in-depth dyadic interviews (n = 40) with heterosexual HIV serodiscordant couples participating at the Thika, Kenya study site, exploring how couples make decisions about using PrEP for HIV prevention. We developed and applied deductive and inductive codes to identify key themes related to experiences of PrEP initiation and use of time-limited PrEP. Couples reported that PrEP offered them an additional strategy to reduce the risk of HIV transmission, meet their fertility desires, and cope with HIV serodiscordance. Remaining HIV negative at follow-up visits reinforced couples' decisions and motivated continued adherence to PrEP. In addition, confidence in their provider's advice and client-friendly services were critical to their decisions to initiate and continue use of PrEP. Strategies for wide-scale PrEP delivery for HIV serodiscordant couples in low resource settings may include building capacity of health providers to counsel on PrEP adoption while addressing couples' concerns and barriers to adoption and continued use.

    Oral antiretroviral preexposure prophylaxis (PrEP) has been shown to decrease human immunodeficiency virus (HIV) incidence in studies of men who have sex with men, heterosexual men and women, and injecting drug users. One study of pericoital tenofovir gel demonstrated that it reduced HIV incidence in South African women. However, other studies of African women failed to demonstrate protection with either oral tenofovir or tenofovir-emtricitabine, or daily tenofovir gel. The magnitude of PrEP protection appears to be highly correlated with medication adherence. New studies are evaluating whether different antiretrovirals, including dapivirine, rilpivirine, maraviroc, and new integrase inhibitors. Different formulations are also being evaluated, including gels, films, vaginal rings, and injectable medication. Although PrEP efficacy has been demonstrated, and several normative bodies (eg, the US Food and Drug Administration) have approved PrEP for clinical use, uptake has been slow. Reasons may include lack of sufficient provider and consumer education, residual concerns about costs, potential long-term toxicities, and behavioral disinhibition. Additional work is under way to determine how to best educate consumers and providers about optimal adherence and to use PrEP in conjunction with risk mitigation. PMID:24926034

    Daily oral tenofovir (TDF)-based pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy and recommended for men and women with substantial risk of HIV acquisition. The peri-conception period, the stage prior to pregnancy when condom use is necessarily reduced, has elevated HIV risk that can be mitigated by PrEP use. Data from a randomized trial suggest that peri-conception PrEP use by HIV-seronegative women does not increase the risk of pregnancy loss, birth defects or congenital anomalies, preterm birth, or infant growth faltering. Women considering PrEP use throughout pregnancy must weigh the known increased risk of HIV acquisition with unknown risks of drug effects on infant growth. PrEP has been used safely by HIV-seronegative men with HIV-seropositive female partners who have become pregnant. As an effective user-controlled HIV prevention strategy, PrEP offers autonomy and empowerment for HIV prevention and can be recommended alongside antiretroviral therapy, fertility screening, vaginal self-insemination, intercourse timed to peak fertility, medically assisted reproduction, and other safer conception strategies to provide multiple options. The integration of PrEP into safer conception programs is warranted and will safely reduce HIV transmission to women, men, and children during the peri-conception period. PMID:26993627

    2016-01-01

    Introduction In contrast to the global trend showing a decline in new HIV infections, the number reported in the World Health Organization (WHO) region of Europe is increasing. Health systems are disparate, but even countries with free access to screening and treatment observe continuing high rates of new infections in key populations, notably men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) is only available in France. This commentary describes the European epidemics and healthcare settings where PrEP could be delivered, how need might be estimated for MSM and the residual barriers to access. Discussion Health systems and government commitment to HIV prevention and care, both financial and political, differ considerably between the countries that make up Europe. A common feature is that funds for prevention are a small fraction of funds for care. Although care is generally good, access is limited in the middle-income countries of Eastern Europe and central Asia, and only 19% of people living with HIV received antiretroviral therapy in 2014. It is challenging to motivate governments or civil society to implement PrEP in the context of this unmet treatment need, which is driven by limited national health budgets and diminishing assistance from foreign aid. The high-income countries of Western Europe have hesitated to embrace PrEP for different reasons, initially due to key gaps in the evidence. Now that PrEP has been shown to be highly effective in European MSM in two randomized controlled trials, it is clear that the major barrier is the cost of the drug which is still on patent, although inadequate health systems and diminishing investment in civil society are also key challenges to overcome. Conclusions The momentum to implement PrEP in European countries is increasing and provides a welcome opportunity to expand and improve clinical services and civil society support focused on HIV and related infections including other sexually transmitted and

    This review concentrates on different aspects of malaria chemoprophylaxis, namely drug combinations, resistance, impact of malaria prevention in pregnancy and cost effectiveness. A MEDLINE search was performed for all articles with the key word‘Malaria’ in the title field and‘Prophylaxis’ in any field. The search was restricted to articles published in English within the last decade(1999-2009). Data sources included review articles published in core clinical journals, cohort studies, interventional studies, case control studies and cross sectional analyses. The mechanism of action, trial evidence of efficacy, side effects and geographical distribution of resistance is discussed for each prophylactic drug regimen. Impact of prophylaxis in pregnancy and the cost considerations are discussed under two separate sub topics.

    Although efficacious forms of malaria chemoprophylaxis currently exist, many travelers to malaria-endemic areas fail to use them effectively. We suggest that taking antimalarial medications prior to travel may prevent more malaria by improving compliance. Treatment regimens of antimalarial drugs taken prior to travel could protect persons for up to one month of exposure. We urge additional testing of pre-travel malaria chemoprophylaxis regimens.

    A number of situations place young children at increased risk of diarrhoea. Among these, the best documented in developing countries is contact with a diarrhoea case in a family or household. The most common application of chemoprophylaxis in developing countries is to prevent cholera or shigellosis among household contacts of known cases. There is little evidence that chemoprophylaxis is effective in reducing diarrhoea morbidity and mortality, except perhaps in travellers. Theoretical calcul...

    Full Text Available Dengue is the most common arboviral disease of humans. There is an unmet need for a therapeutic intervention that reduces the duration and severity of dengue symptoms and diminishes the likelihood of severe complications. To this end, there are active discovery efforts in industry and academia to develop interventions, with a focus on small molecule inhibitors of dengue virus replication that are suitable for therapy or chemoprophylaxis. Advancements in animal models of dengue virus infection together with the possibility of a dengue human infection model have further enhanced the platform for dengue drug discovery. Whilst drug discovery efforts gestate, there are ongoing clinical research designed to benefit today's patients, including trials of supportive care interventions, and descriptive studies that should improve the ability of clinicians to make an accurate diagnosis early in the illness course and to identify patients most at risk of progression to severe disease. This review provides a state of the art summary of dengue drug discovery, clinical trials, and supportive allied research and reflects discussions at the 2nd International Dengue Therapeutics Workshop held in Ho Chi Minh City, Vietnam, in December 2013.

    Full Text Available Abstract Background In a number of malaria endemic regions, tourists and travellers face a declining risk of travel associated malaria, in part due to successful malaria control. Many millions of visitors to these regions are recommended, via national and international policy, to use chemoprophylaxis which has a well recognized morbidity profile. To evaluate whether current malaria chemo-prophylactic policy for travellers is cost effective when adjusted for endemic transmission risk and duration of exposure. a framework, based on partial cost-benefit analysis was used Methods Using a three component model combining a probability component, a cost component and a malaria risk component, the study estimated health costs avoided through use of chemoprophylaxis and costs of disease prevention (including adverse events and pre-travel advice for visits to five popular high and low malaria endemic regions and malaria transmission risk using imported malaria cases and numbers of travellers to malarious countries. By calculating the minimal threshold malaria risk below which the economic costs of chemoprophylaxis are greater than the avoided health costs we were able to identify the point at which chemoprophylaxis would be economically rational. Results The threshold incidence at which malaria chemoprophylaxis policy becomes cost effective for UK travellers is an accumulated risk of 1.13% assuming a given set of cost parameters. The period a travellers need to remain exposed to achieve this accumulated risk varied from 30 to more than 365 days, depending on the regions intensity of malaria transmission. Conclusions The cost-benefit analysis identified that chemoprophylaxis use was not a cost-effective policy for travellers to Thailand or the Amazon region of Brazil, but was cost-effective for travel to West Africa and for those staying longer than 45 days in India and Indonesia.

    We compared outcomes in 2 groups undergoing total knee arthroplasty (TKA) with different blood-saving strategies (ie, chemoprophylaxis vs reinfusion). We hypothesized that chemoprophylaxis would lead to reduced blood loss and fewer transfusions, with no increase in associated complications. Group A was a prospective series of 91 consecutive cemented TKAs undertaken with chemoprophylaxis to reduce bleeding and blood allogeneic exposure. Group B consisted of 44 historical TKAs undertaken with postoperative reinfusion. With the exception of mean patient age (group A, 74.3 years; group B, 70.9 years; P=.006), there were no statistically significant differences between the 2 study groups.Mean total blood loss throughout the 7-day perioperative period was 1490 mL in group A and 1828 mL in group B. The rate of blood transfusion in group A was almost zero. In group B, 41 of 44 patients were administered blood intravenously. Despite the absence of autotransfusion, postoperative hemoglobin levels were significantly higher in group A than in group B. No major bleeding complications emerged in the immediate postoperative period in either group.Chemoprophylaxis proved superior to reinfusion at decreasing blood transfusion requirements in the routine daily setting of unilateral cemented primary TKA.

    Full Text Available Abstract Background Numbers of travellers visiting friends and relatives (VFRs from Europe to malaria endemic countries are increasing and include long-term and second generation immigrants, who represent the major burden of malaria cases imported back into Europe. Most recommendations for malaria chemoprophylaxis lack a solid evidence base, and often fail to address the cultural, social and economic needs of VFRs. Methods European travel medicine experts, who are members of TropNetEurop, completed a sequential series of questionnaires according to the Delphi method. This technique aims at evaluating and developing a consensus through repeated iterations of questionnaires. The questionnaires in this study included questions about professional experience with VFRs, controversial issues in malaria prophylaxis, and 16 scenarios exploring indications for prescribing and choice of chemoprophylaxis. Results The experience of participants was rather diverse as was their selection of chemoprophylaxis regimen. A significant consensus was observed in only seven of 16 scenarios. The analysis revealed a wide variation in prescribing choices with preferences grouped by region of practice and increased prescribing seen in Northern Europe compared to Central Europe. Conclusions Improving the evidence base on efficacy, adherence to chemoprophylaxis and risk of malaria and encouraging discussion among experts, using techniques such as the Delphi method, may reduce the variability in prescription in European travel clinics.

    Mefloquine has been licensed and registered in Japan for chemoprophylaxis against malaria since 2001. Guidelines for the prevention of malaria for Japanese overseas travelers were published by a group of malaria specialists under the auspices of the Japanese Society of Tropical Medicine and the Ministry of Health, Labor and Welfare, but not until March 2005. We implemented these guidelines in our clinic at the International Medical Center of Japan in Tokyo and, to better understand whether these guidelines are optimally useful, we conducted a study of Japanese travelers who visited our clinic seeking pertinent information and prophylaxis against malaria. The study group comprised 52 individuals who visited our clinic during the period October 2004 through June 2005 prior to travel abroad. On the basis of the above-mentioned guidelines, mefloquine was given to 27 of these individuals, 22 of whom were judged to need regular chemoprophylaxis. Mefloquine was not recommended to the other 25 individuals because their stays abroad would have been too long to avoid possible side effects or too short for symptoms to appear. In fact, some were traveling to malaria-free areas. Of the 27 individuals given mefloquine, 7 (26%) reported side effects, such as headache, vertigo, and nausea, 17 (63%) reported no side-effects, and the other 3 (11%) were unable to be followed. The diversity of destinations and accompanying malaria risks makes it very difficult for us to administer chemoprophylaxis to overseas travelers appropriately. The guidelines proved to be somewhat useful, but further experience in malaria chemoprophylaxis is needed for physicians to provide reliable pre-travel consultation. PMID:17547042

    2010-02-01

    Full Text Available Abstract Background The effectiveness of malaria chemoprophylaxis is limited by the lack of compliance whose determinants are not well known. Methods The compliance with malaria chemoprophylaxis has been estimated and analysed by validated questionnaires administered before and after the short-term missions (about four months in five tropical African countries of 2,093 French soldiers from 19 military companies involved in a prospective cohort study. "Correct compliance" was defined as "no missed doses" of daily drug intake during the entire mission and was analysed using multiple mixed-effect logistic regression model. Results The averaged prevalence rate of correct compliance was 46.2%, ranging from 9.6%to 76.6% according to the companies. Incorrect compliance was significantly associated with eveningness (p = 0.028, a medical history of clinical malaria (p Conclusions The identification of circumstances and profiles of persons at higher risk of lack of compliance would pave the way to specifically targeted strategies aimed to improve compliance with malaria chemoprophylaxis and, therefore, its effectiveness.

    2009-10-01

    Full Text Available Abstract Background Malaria chemoprophylaxis compliance is suboptimal among French soldiers despite the availability of free malaria chemoprophylaxis and repeated health education before, during and after deployment to malaria endemic areas. Methods In 2007, a randomized controlled study was performed among a cohort of French soldiers returning from Côte d'Ivoire to assess the feasibility and acceptability of sending a daily short message service (SMS reminder message via mobile device to remind soldiers to take their malaria chemoprophylaxis, and to assess the impact of the daily reminder SMS on chemoprophylaxis compliance. Malaria chemoprophylaxis consisted of a daily dose of 100 mg doxycycline monohydrate, which began upon arrival in Côte d'Ivoire and was to be continued for 28 days following return to France. Feasibility and acceptability were assessed by questionnaire. Cohort members were followed for a 28 day period, with compliance assessed by use of an electronic medication monitoring device, from which several indicators were developed: daily proportion of compliant individuals, average number of pills taken, and early discontinuation. Results Among 424 volunteers randomized to the study, 47.6% were assigned to the SMS group and 52.3% to the control group. Approximately 90% of subjects assigned to the SMS group received a daily SMS at midday during the study. Persons of the SMS group agreed more frequently that SMS reminders were very useful and that the device was not annoying. Compliance did not vary significantly between groups across the compliance indicators. Conclusion SMS did not increase malaria chemoprophylaxis compliance above baseline, likely because the persons did not benefit from holidays after the return and stayed together. So the reminder by SMS was noted by all subjects of the study. Another study should be done to confirm these results on soldiers going on holidays from employment after return or with individual

    To date, little data on pre-exposure prophylaxis (PrEP) users outside of the clinical trial setting are available. A repeated cross-sectional survey of one of the largest social and sexual networking websites for men who have sex with men (MSM) in the United States was conducted in August 2013 (Wave 1) and January 2014 (Wave 2). Multivariable logistic regression models were used to assess factors associated with having heard of and having taken post-exposure prophylaxis (PEP) and PrEP in Wave 1 (N = 4043) and Wave 2 (N = 2737) separately. In Wave 1, 147 (3.6 %) and 61 (1.5 %) reported using PEP and PrEP, respectively, compared to 119 (4.4 %) and 62 (2.3 %) in Wave 2. Higher-risk sexual behaviors were associated with having taken PEP and PrEP, and previous PEP use was associated with having taken PrEP. Understanding factors that are associated with early use of PrEP may help inform wider utilization of PrEP by at risk MSM. PMID:26530863

  1. Variations in chemoprophylaxis for meningococcal disease: a retrospective case note review, analysis of routine prescribing data and questionnaire of general practitioners

    2001-12-01

    Full Text Available Abstract Background Invasive meningococcal disease is a significant cause of mortality and morbidity in the UK. Administration of chemoprophylaxis to close contacts reduces the risk of a secondary case. However, unnecessary chemoprophylaxis may be associated with adverse reactions, increased antibiotic resistance and removal of organisms, such as Neisseria lactamica, which help to protect against meningococcal disease. Limited evidence exists to suggest that overuse of chemoprophylaxis may occur. This study aimed to evaluate prescribing of chemoprophylaxis for contacts of meningococcal disease by general practitioners and hospital staff. Methods Retrospective case note review of cases of meningococcal disease was conducted in one health district from 1st September 1997 to 31st August 1999. Routine hospital and general practitioner prescribing data was searched for chemoprophylactic prescriptions of rifampicin and ciprofloxacin. A questionnaire of general practitioners was undertaken to obtain more detailed information. Results Prescribing by hospital doctors was in line with recommendations by the Consultant for Communicable Disease Control. General practitioners prescribed 118% more chemoprophylaxis than was recommended. Size of practice and training status did not affect the level of additional prescribing, but there were significant differences by geographical area. The highest levels of prescribing occurred in areas with high disease rates and associated publicity. However, some true close contacts did not appear to receive prophylaxis. Conclusions Receipt of chemoprophylaxis is affected by a series of patient, doctor and community interactions. High publicity appears to increase demand for prophylaxis. Some true contacts do not receive appropriate chemoprophylaxis and are left at an unnecessarily increased risk.

    Brooke E Nichols

    Full Text Available BACKGROUND: Pre-exposure prophylaxis (PrEP with tenofovir and emtricitabine effectively prevents new HIV infections. The optimal scenario for implementing PrEP where most infections are averted at the lowest cost is unknown. We determined the impact of different PrEP strategies on averting new infections, prevalence, drug resistance and cost-effectiveness in Macha, a rural setting in Zambia. METHODS: A deterministic mathematical model of HIV transmission was constructed using data from the Macha epidemic (antenatal prevalence 7.7%. Antiretroviral therapy is started at CD4<350 cells/mm(3. We compared the number of infections averted, cost-effectiveness, and potential emergence of drug resistance of two ends of the prioritization spectrum: prioritizing PrEP to half of the most sexually active individuals (5-15% of the total population, versus randomly putting 40-60% of the total population on PrEP. RESULTS: Prioritizing PrEP to individuals with the highest sexual activity resulted in more infections averted than a non-prioritized strategy over ten years (31% and 23% reduction in new infections respectively, and also a lower HIV prevalence after ten years (5.7%, 6.4% respectively. The strategy was very cost-effective at $323 per quality adjusted life year gained and appeared to be both less costly and more effective than the non-prioritized strategy. The prevalence of drug resistance due to PrEP was as high as 11.6% when all assumed breakthrough infections resulted in resistance, and as low as 1.3% when 10% of breakthrough infections resulted in resistance in both our prioritized and non-prioritized scenarios. CONCLUSIONS: Even in settings with low test rates and treatment retention, the use of PrEP can still be a useful strategy in averting infections. Our model has shown that PrEP is a cost-effective strategy for reducing HIV incidence, even when adherence is suboptimal and prioritization is imperfect.

    Multimodal thromboprophylaxis encompasses preoperative VTE risk stratification, regional anesthesia, mechanical prophylaxis, and early mobilization. We determined if aspirin can be safely used for adjuvant chemoprophylaxis in patients who have a low thromboembolic risk. 1016 consecutive patients undergoing TKA received multimodal thromboprophylaxis. Aspirin was used in 67% of patients and Coumadin 33% (high risk patients, or who were on Coumadin before surgery). This study group was compared to 1001 consecutive patients who received multimodal thromboprophylaxis and routine Coumadin chemoprophylaxis. There was no significant difference in rates of VTE, PE, bleeding, complications, readmission and 90-day mortality between the two groups. There was a significantly higher rate of wound related complications in the control group (p=0.03). Multimodal thromboprophylaxis with aspirin given to the majority of patients at a low VTE risk is safe and effective in patients undergoing primary TKA.

    Background The Institute of Medicine report on potential reduced exposure products (PREPs) recommends that advertising and labelling be regulated to prevent explicitly or implicitly false or misleading claims. Belief that a product is less harmful may increase use or prevent smoking cessation. Objective To determine the effect of altering advertisement features on smokers’ beliefs of the harm exposure from a PREP. Methods A Quest advertisement was digitally altered using computer software and presented to participants using web-based television recruitment contracted through a survey company. 500 current smokers completed demographic and smoking history questions, were randomised to view one of three advertisement conditions, then completed eight items assessing their beliefs of the harmfulness of the product. Advertisement conditions included the original, unaltered advertisement; a “red” condition where the cigarette packages were digitally altered to the colour red, implying increased harm potential; and a “no text” condition where all text was removed to reduce explicit product information. Polytomous logistic regression, using “incorrect,” “unsure” and “correct” as outcomes, and advertisement type and covariates as predictors, was used for analyses. Results Participants randomised to the “no text” advertisement were less likely to be incorrect in their beliefs that Quest cigarettes are lower in tar, less addictive, less likely to cause cancer, have fewer chemicals, healthier and make smoking safer. Conclusions Smokers can form false beliefs about the harmfulness of PREP products based on how the PREPs are marketed. Careful examination must be undertaken to provide empirical evidence to better formulate regulatory principles of PREP advertising. PMID:18768457

    One efficacious strategy to help prevent HIV is oral pre-exposure prophylaxis (PrEP), a daily regimen of antiretroviral treatment taken by HIV-negative individuals. Two of the recommendations of Centers for Disease Control and Prevention (CDC) guidelines for PrEP pertain to being in a relationship (i.e., male couples). Despite the recognition of how primary partners in male couples' relationships shape HIV risk and CDC's PrEP guidelines, there is a paucity of data that examine HIV-negative male couples' attitudes toward PrEP use and using PrEP with a sexual agreement. A sexual agreement is an explicit agreement made between two individuals about what sex and other related behaviors may occur within and outside of their relationship. In this qualitative study, we examine HIV-negative male couples' attitudes toward PrEP use and whether they thought PrEP could be integrated into a sexual agreement. Data for this study are drawn from couple-level interviews conducted in 2014 with 29 HIV-negative male couples who had a sexual agreement and were from Atlanta or Detroit. Both passive (e.g., flyers) and active (e.g., targeted Facebook advertisements) recruitment methods were used; the sample was stratified by agreement type. Thematic analysis was applied to identify the following themes regarding HIV-negative male couples' attitudes toward PrEP use: (1) PrEP and condom use; (2) concerns about PrEP (e.g., effectiveness, side effects, and promoting sexually risky behavior); and (3) accessibility of PrEP. Some thought PrEP could be a part of couples' agreement because it could help reduce sexual anxiety and sexual risk, and would help keep the couple safe. Others described PrEP use with an agreement as something for "others". Some were also concerned that incorporating PrEP could usurp the need for a sexual agreement in a couples' relationship. These themes highlight the need to improve informational messaging and promotion efforts about PrEP among HIV-negative male couples

    Full Text Available Introduction. Men who have sex with men (MSM are disproportionately impacted by HIV globally. Easily accessible combination HIV prevention strategies, tailored to the needs of MSM, are needed to effectively address the AIDS pandemic. Methods and Materials. We conducted a cross-sectional study among MSM (n=3748 from 145 countries from April to August 2012. Using multivariable random effects models, we examined factors associated with acceptability of preexposure prophylaxis (PrEP and access to condoms, lubricants, HIV testing, and HIV treatment. Results. Condoms and lubricants were accessible to 35% and 22% of all respondents, respectively. HIV testing was accessible to 35% of HIV-negative respondents. Forty-three percent of all HIV-positive respondents reported that antiretroviral therapy was easily accessible. Homophobia, outness, and service provider stigma were significantly associated with reduced access to services. Conversely, community engagement, connection to gay community, and comfort with service providers were associated with increased access. PrEP acceptability was associated with lower PrEP-related stigma, less knowledge about PrEP, less outness, higher service provider stigma, and having experienced violence for being MSM. Conclusions. Ensuring HIV service access among MSM will be critical in maximizing the potential effectiveness of combination approaches, especially given the interdependence of both basic and newer interventions like PrEP. Barriers and facilitators of HIV service access for MSM should be better understood and addressed.

    Prep1 is a homeodomain transcription factor that is essential in embryonic development and functions in the adult as a tumor suppressor. We show here that Prep1 is involved in maintaining genomic stability and preventing neoplastic transformation. Hypomorphic homozygous Prep1(i/i) fetal liver cells and mouse embryonic fibroblasts (MEFs) exhibit increased basal DNA damage and normal DNA damage response after γ-irradiation compared with WT. Cytogenetic analysis shows the presence of numerous chromosomal aberrations and aneuploidy in very early-passage Prep1(i/i) MEFs. In human fibroblasts, acute Prep1 down-regulation by siRNA induces DNA damage response, like in Prep1(i/i) MEFs, together with an increase in heterochromatin-associated modifications: rapid increase of histone methylation and decreased transcription of satellite DNA. Ectopic expression of Prep1 rescues DNA damage and heterochromatin methylation. Inhibition of Suv39 activity blocks the chromatin but not the DNA damage phenotype. Finally, Prep1 deficiency facilitates cell immortalization, escape from oncogene-induced senescence, and H-Ras(V12)-dependent transformation. Importantly, the latter can be partially rescued by restoration of Prep1 level. The results show that the tumor suppressor role of Prep1 is associated with the maintenance of genomic stability.

    2016-10-01

    Full Text Available Introduction: HIV epidemics in the Asia-Pacific region are concentrated among men who have sex with men (MSM and other key populations. Pre-exposure prophylaxis (PrEP is an effective HIV prevention intervention and could be a potential game changer in the region. We discuss the progress towards PrEP implementation in the Asia-Pacific region, including opportunities and barriers. Discussion: Awareness about PrEP in the Asia-Pacific is still low and so are its levels of use. A high proportion of MSM who are aware of PrEP are willing to use it. Key PrEP implementation barriers include poor knowledge about PrEP, limited access to PrEP, weak or non-existent HIV prevention programmes for MSM and other key populations, high cost of PrEP, stigma and discrimination against key populations and restrictive laws in some countries. Only several clinical trials, demonstration projects and a few larger-scale implementation studies have been implemented so far in Thailand and Australia. However, novel approaches to PrEP implementation have emerged: researcher-, facility- and community-led models of care, with PrEP services for fee and for free. The WHO consolidated guidelines on HIV testing, treatment and prevention call for an expanded access to PrEP worldwide and have provided guidance on PrEP implementation in the region. Some countries like Australia have released national PrEP guidelines. There are growing community leadership and consultation processes to initiate PrEP implementation in Asia and the Pacific. Conclusions: Countries of the Asia-Pacific region will benefit from adding PrEP to their HIV prevention packages, but for many this is a critical step that requires resourcing. Having an impact on the HIV epidemic requires investment. The next years should see the region transitioning from limited PrEP implementation projects to growing access to PrEP and expansion of HIV prevention programmes.

    Introduction HIV epidemics in the Asia-Pacific region are concentrated among men who have sex with men (MSM) and other key populations. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention intervention and could be a potential game changer in the region. We discuss the progress towards PrEP implementation in the Asia-Pacific region, including opportunities and barriers. Discussion Awareness about PrEP in the Asia-Pacific is still low and so are its levels of use. A high proportion of MSM who are aware of PrEP are willing to use it. Key PrEP implementation barriers include poor knowledge about PrEP, limited access to PrEP, weak or non-existent HIV prevention programmes for MSM and other key populations, high cost of PrEP, stigma and discrimination against key populations and restrictive laws in some countries. Only several clinical trials, demonstration projects and a few larger-scale implementation studies have been implemented so far in Thailand and Australia. However, novel approaches to PrEP implementation have emerged: researcher-, facility- and community-led models of care, with PrEP services for fee and for free. The WHO consolidated guidelines on HIV testing, treatment and prevention call for an expanded access to PrEP worldwide and have provided guidance on PrEP implementation in the region. Some countries like Australia have released national PrEP guidelines. There are growing community leadership and consultation processes to initiate PrEP implementation in Asia and the Pacific. Conclusions Countries of the Asia-Pacific region will benefit from adding PrEP to their HIV prevention packages, but for many this is a critical step that requires resourcing. Having an impact on the HIV epidemic requires investment. The next years should see the region transitioning from limited PrEP implementation projects to growing access to PrEP and expansion of HIV prevention programmes. PMID:27760688

    Six randomized clinical trials have been implemented to examine the efficacy of tenofovir disoproxil fumarate (TDF) and/or TDF/emtricitabine (TDF/FTC) as preexposure prophylaxis for HIV-1 infection (PrEP). Although largely complementary, the six trials have many similar features. As the earliest results become available, an urgent question may arise regarding whether changes should be made in the conduct of the other trials.

    BACKGROUND Antiretroviral chemoprophylaxis before exposure is a promising approach for the prevention of human immunodeficiency virus (HIV) acquisition. METHODS We randomly assigned 2499 HIV-seronegative men or transgender women who have sex with men to receive a combination of two oral antiretroviral drugs, emtricitabine and tenofovir disoproxil fumarate (FTC–TDF), or placebo once daily. All subjects received HIV testing, risk-reduction counseling, condoms, and management of sexually transmitted infections. RESULTS The study subjects were followed for 3324 person-years (median, 1.2 years; maximum, 2.8 years). Of these subjects, 10 were found to have been infected with HIV at enrollment, and 100 became infected during follow-up (36 in the FTC–TDF group and 64 in the placebo group), indicating a 44% reduction in the incidence of HIV (95% confidence interval, 15 to 63; P = 0.005). In the FTC–TDF group, the study drug was detected in 22 of 43 of seronegative subjects (51%) and in 3 of 34 HIV-infected subjects (9%) (P<0.001). Nausea was reported more frequently during the first 4 weeks in the FTC–TDF group than in the placebo group (P<0.001). The two groups had similar rates of serious adverse events (P = 0.57). CONCLUSIONS Oral FTC–TDF provided protection against the acquisition of HIV infection among the subjects. Detectable blood levels strongly correlated with the prophylactic effect.

It is important for patient safety to detect drug-event combinations and analyze by appropriate statistical methods. Mefloquine is used as chemoprophylaxis for travelers going to regions with known chloroquine-resistant Plasmodium falciparum malaria. As such, there is a concern about serious adverse events associated with mefloquine chemoprophylaxis. The objective of the present study was to assess whether any signal would be detected for the serious adverse events of mefloquine, based on data in clinicoepidemiological studies.Materials and methods: We extracted data on adverse events related to mefloquine chemoprophylaxis from the two published datasets. Disproportionality reporting of adverse events such as neuropsychiatric events and other adverse events was presented in the 2 × 2 contingency table. Reporting odds ratio and corresponding 95% confidence interval [CI] data-mining algorithm was applied for the signal detection. The safety signals are considered significant when the ROR estimates and the lower limits of the corresponding 95% CI are ≥2.Results: Two datasets addressing adverse events of mefloquine chemoprophylaxis (one from a published article and one from a Cochrane systematic review were included for analyses. Reporting odds ratio 1.58, 95% CI: 1.49–1.68 based on published data in the selected article, and 1.195, 95% CI: 0.94–1.44 based on data in the selected Cochrane review. Overall, in both datasets, the reporting odds ratio values of lower 95% CI were less than 2.Conclusion: Based on available data, findings suggested that signals for serious adverse events pertinent to neuropsychiatric event were

    Experimental whole-parasite immunization through concurrent administration of infectious Plasmodium sporozoites with drugs that prevent pathogenic blood-stage infection represents the current benchmark in malaria vaccine development. Key questions concerning translation remain, including the requirement for single-dose drug regimens that can reliably prevent breakthrough infections. We assessed the feasibility and efficacy of immunization with single-dose piperaquine chemoprophylaxis and concurrent sporozoite administration (PPQ-CPS) in the murine P. berghei ANKA/C57BL/6 infection model. We demonstrate that PPQ-CPS is protective with an efficacy comparable to previous findings using whole-parasite immunization under chloroquine chemoprophylaxis. PPQ-CPS immunization resulted in an expansion of intrahepatic and intrasplenic effector memory CD8(+) T cells. In summary, PPQ-CPS appears to be a safe and efficacious immunization regimen in the rodent malaria model and may thus become an important improvement regarding the translation of whole-parasite immunization toward a human malaria vaccine.

    Full Text Available Prep1 is a developmentally essential TALE class homeodomain transcription factor. In zebrafish and mouse, Prep1 is already ubiquitously expressed at the earliest stages of development, with important tissue-specific peculiarities. The Prep1 gene in mouse is developmentally essential and has haploinsufficient tumor suppressor activity [1]. We have determined the human Prep1 transcription start site (TSS by primer extension analysis and identified, within 20 bp, the transcription start region (TSR of the zebrafish Prep1.1 promoter. The functions of the zebrafish 5' upstream sequences were analyzed both by transient transfections in Hela Cells and by injection in zebrafish embryos. This analysis revealed a complex promoter with regulatory sequences extending up to -1.8, possibly -5.0 Kb, responsible for tissue specific expression. Moreover, the first intron contains a conserved tissue-specific enhancer both in zebrafish and in human cells. Finally, a two nucleotides mutation of an EGR-1 site, conserved in all species including human and zebrafish and located at a short distance from the TSS, destroyed the promoter activity of the -5.0 Kb promoter. A transgenic fish expressing GFP under the -1.8 Kb zebrafish promoter/enhancer co-expressed GFP and endogenous Prep1.1 during embryonic development. In the adult fish, GFP was expressed in hematopoietic regions like the kidney, in agreement with the essential function of Prep1 in mouse hematopoiesis. Sequence comparison showed conservation from man to fish of the sequences around the TSS, within the first intron enhancer. Moreover, about 40% of the sequences spread throughout the 5 Kbof the zebrafish promoter are concentrated in the -3 to -5 Kb of the human upstream region.

    The Scientific Knowledge for Indian Learning and Leadership (SKILL) precollege college program of the South Dakota School of Mines and Technology concluded the 1994 PREP program on July 22, 1994. The program graduated 22 students from the 4-week residential math/science program for American Indian students. Primary academic focus was physics (30 hours); each student was given a bicycle to solve problems on angular momentum and mechanical advantage. Mathematical calculations and problem solving exercises were done in mathematics class (20 hours). Preliminary results in math, physics, and geology show dramatic increases in student achievement over the 4- week period. The program paired every two students with a faculty member or research scientist, and each team completed a research project.

    Full Text Available Planaria continue to blossom as a model system for understanding all aspects of regeneration. They provide an opportunity to understand how the replacement of missing tissues from preexisting adult tissue is orchestrated at the molecular level. When amputated along any plane, planaria are capable of regenerating all missing tissue and rescaling all structures to the new size of the animal. Recently, rapid progress has been made in understanding the developmental pathways that control planarian regeneration. In particular Wnt/beta-catenin signaling is central in promoting posterior fates and inhibiting anterior identity. Currently the mechanisms that actively promote anterior identity remain unknown. Here, Smed-prep, encoding a TALE class homeodomain, is described as the first gene necessary for correct anterior fate and patterning during planarian regeneration. Smed-prep is expressed at high levels in the anterior portion of whole animals, and Smed-prep(RNAi leads to loss of the whole brain during anterior regeneration, but not during lateral regeneration or homeostasis in intact worms. Expression of markers of different anterior fated cells are greatly reduced or lost in Smed-prep(RNAi animals. We find that the ectopic anterior structures induced by abrogation of Wnt signaling also require Smed-prep to form. We use double knockdown experiments with the S. mediterranea ortholog of nou-darake (that when knocked down induces ectopic brain formation to show that Smed-prep defines an anterior fated compartment within which stem cells are permitted to assume brain fate, but is not required directly for this differentiation process. Smed-prep is the first gene clearly implicated as being necessary for promoting anterior fate and the first homeobox gene implicated in establishing positional identity during regeneration. Together our results suggest that Smed-prep is required in stem cell progeny as they form the anterior regenerative blastema and is

  10. elPrep: High-Performance Preparation of Sequence Alignment/Map Files for Variant Calling.

    Directory of Open Access Journals (Sweden)

    Charlotte Herzeel

    Full Text Available elPrep is a high-performance tool for preparing sequence alignment/map files for variant calling in sequencing pipelines. It can be used as a replacement for SAMtools and Picard for preparation steps such as filtering, sorting, marking duplicates, reordering contigs, and so on, while producing identical results. What sets elPrep apart is its software architecture that allows executing preparation pipelines by making only a single pass through the data, no matter how many preparation steps are used in the pipeline. elPrep is designed as a multithreaded application that runs entirely in memory, avoids repeated file I/O, and merges the computation of several preparation steps to significantly speed up the execution time. For example, for a preparation pipeline of five steps on a whole-exome BAM file (NA12878, we reduce the execution time from about 1:40 hours, when using a combination of SAMtools and Picard, to about 15 minutes when using elPrep, while utilising the same server resources, here 48 threads and 23GB of RAM. For the same pipeline on whole-genome data (NA12878, elPrep reduces the runtime from 24 hours to less than 5 hours. As a typical clinical study may contain sequencing data for hundreds of patients, elPrep can remove several hundreds of hours of computing time, and thus substantially reduce analysis time and cost.

    TALE (three amino acids loop extension) homeodomain transcription factors are required in various steps of embryo development, in many adult physiological functions, and are involved in important pathologies. This review focuses on the PREP, MEIS, and PBX sub-families of TALE factors and aims at giving information on their biochemical properties, i.e., structure, interactors, and interaction surfaces. Members of the three sets of protein form dimers in which the common partner is PBX but they can also directly interact with other proteins forming higher-order complexes, in particular HOX. Finally, recent advances in determining the genome-wide DNA-binding sites of PREP1, MEIS1, and PBX1, and their partial correspondence with the binding sites of some HOX proteins, are reviewed. These studies have generated a few general rules that can be applied to all members of the three gene families. PREP and MEIS recognize slightly different consensus sequences: PREP prefers to bind to promoters and to have PBX as a DNA-binding partner; MEIS prefers HOX as partner, and both PREP and MEIS drive PBX to their own binding sites. This outlines the clear individuality of the PREP and MEIS proteins, the former mostly devoted to basic cellular functions, the latter more to developmental functions.

  14. Cytoplasmic Prep1 interacts with 4EHP inhibiting Hoxb4 translation.

    Directory of Open Access Journals (Sweden)

    J Carlos Villaescusa

    Full Text Available BACKGROUND: Homeobox genes are essential for embryonic patterning and cell fate determination. They are regulated mostly at the transcriptional level. In particular, Prep1 regulates Hox transcription in association with Pbx proteins. Despite its nuclear role as a transcription factor, Prep1 is located in the cytosol of mouse oocytes from primary to antral follicles. The homeodomain factor Bicoid (Bcd has been shown to interact with 4EHP (eukaryotic translation initiation factor 4E homolog protein to repress translation of Caudal mRNA and to drive Drosophila embryo development. Interestingly, Prep1 contains a putative binding motif for 4EHP, which may reflect a novel unknown function. METHODOLOGY/PRINCIPAL FINDINGS: In this paper we show by confocal microscopy and deconvolution analysis that Prep1 and 4EHP co-localize in the cytosol of growing mouse oocytes, demonstrating their interaction by co-immunoprecipitation and pull-down experiments. A functional 4EHP-binding motif present in Prep1 has been also identified by mutagenesis analysis. Moreover, Prep1 inhibits (>95% the in vitro translation of a luciferase reporter mRNA fused to the Hoxb4 3'UTR, in the presence of 4EHP. RNA electrophoretic mobility shift assay was used to demonstrate that Prep1 binds the Hoxb4 3'UTR. Furthermore, conventional histology and immunohistochemistry has shown a dramatic oocyte growth failure in hypomorphic mouse Prep1(i/i females, accompanied by an increased production of Hoxb4. Finally, Hoxb4 overexpression in mouse zygotes showed a slow in vitro development effect. CONCLUSIONS: Prep1 has a novel cytoplasmic, 4EHP-dependent, function in the regulation of translation. Mechanistically, the Prep1-4EHP interaction might bridge the 3'UTR of Hoxb4 mRNA to the 5' cap structure. This is the first demonstration that a mammalian homeodomain transcription factor regulates translation, and that this function can be possibly essential for the development of female germ cells

    Transgender women are at high risk of HIV infection, with younger transgender women (YTW) particularly vulnerable. Pre-Exposure Prophylaxis (PrEP) has shown efficacy in reducing HIV acquisition, but little is known about PrEP indication or initiation among YTW. Baseline data from 180 YTW age 18-29 years enrolled in Project LifeSkills, an on-going HIV prevention intervention for YTW, were analyzed to examine factors associated with PrEP indication. The sample (mean age = 23.4, SD = 3.2) was comprised largely of women of color (69 %) and of low socioeconomic status (71 % unemployed). Overall, 62 % met criteria for PrEP indication, but only 5 % reported ever taking PrEP. Factors associated with increased odds of PrEP indication were: PrEP interest (aOR 3.24; 95 % CI 1.44, 7.33), number of recent anal sex partners (aOR 1.23; 95 % CI 1.04, 1.46), and lower collective self-esteem scores (aOR 0.67; 95 % CI 0.47, 0.94). Despite high levels of PrEP indication, there remain low levels of PrEP awareness and uptake among YTW. PMID:26336946

    Full Text Available Introduction: HIV incidence remains high among young women in sub-Saharan Africa in spite of scale-up of HIV testing, behavioural interventions, antiretroviral treatment and medical male circumcision. There is a critical need to critique past approaches and learn about the most effective implementation of evidence-based HIV prevention strategies, particularly emerging interventions such as pre-exposure prophylaxis (PrEP. Discussion: Women in sub-Saharan Africa are at increased risk of HIV during adolescence and into their 20s, in part due to contextual factors including gender norms and relationship dynamics, and limited access to reproductive and sexual health services. We reviewed behavioural, behavioural economic and biomedical approaches to HIV prevention for young African women, with a particular focus on the barriers, opportunities and implications for implementing PrEP in this group. Behavioural interventions have had limited impact in part due to not effectively addressing the context, broader sexual norms and expectations, and structural factors that increase risk and vulnerability. Of biomedical HIV prevention strategies that have been tested, daily oral PrEP has the greatest evidence for protection, although adherence was low in two placebo-controlled trials in young African women. Given high efficacy and effectiveness in other populations, demonstration projects of open-label PrEP in young African women are needed to determine the most effective delivery models and whether women at substantial risk are motivated and able to use oral PrEP with sufficient adherence to achieve HIV prevention benefits. Conclusions: Social marketing, adherence support and behavioural economic interventions should be evaluated as part of PrEP demonstration projects among young African women in terms of their effectiveness in increasing demand and optimizing uptake and effective use of PrEP. Lessons learned through evaluations of implementation strategies

    Full Text Available Abstract Background Over the past decade, tobacco companies have introduced cigarettes and smokeless tobacco products (known as Potential Reduced Exposure Products, PREPs with purportedly lower levels of some toxins than conventional cigarettes and smokeless products. It is essential that public health agencies monitor awareness, interest, use, and perceptions of these products so that their impact on population health can be detected at the earliest stages. Methods This paper reviews and critiques existing strategies for measuring awareness of PREPs from 16 published and unpublished studies. From these measures, we developed new surveillance items and subjected them to two rounds of cognitive testing, a common and accepted method for evaluating questionnaire wording. Results Our review suggests that high levels of awareness of PREPs reported in some studies are likely to be inaccurate. Two likely sources of inaccuracy in awareness measures were identified: 1 the tendency of respondents to misclassify "no additive" and "natural" cigarettes as PREPs and 2 the tendency of respondents to mistakenly report awareness as a result of confusion between PREPs brands and similarly named familiar products, for example, Eclipse chewing gum and Accord automobiles. Conclusion After evaluating new measures with cognitive interviews, we conclude that as of winter 2006, awareness of reduced exposure products among U.S. smokers was likely to be between 1% and 8%, with the higher estimates for some products occurring in test markets. Recommended measurement strategies for future surveys are presented.

    Pre-exposure prophylaxis (PrEP) is effective for preventing HIV among HIV-serodiscordant heterosexual couples. Gender roles may influence perceived personal and social risks related to HIV-prevention behaviors and may affect use of PrEP. In this study, interviews and focus groups were conducted with 68 individuals from 34 mutually disclosed serodiscordant heterosexual partnerships in Thika, Kenya. Sociocultural factors that affect adherence to PrEP were explored using grounded analysis. Three factors were identified, which shape perceptions of PrEP: gendered power dynamics and control over decision-making in the household; conflicts between risk-reduction strategies and male sexual desire; culture-bound definitions of women's work. Adherence to PrEP in the Partners PrEP Study was high; however, participants articulated conflicting interests related to PrEP in connection with traditional gender roles. The successful delivery of PrEP will require understanding of key social factors, particularly related to gender and dyadic dynamics around HIV serostatus. PMID:26754017

    The frequent conflation of transgender ('trans') women with 'men who have sex with men (MSM)' in HIV prevention obscures trans women's unique gender identities, social and behavioural vulnerabilities, and their disproportionately high rates of HIV infection. Pre-exposure prophylaxis (PrEP) is an efficacious biomedical HIV prevention approach. However, trans women are underrepresented in PrEP research, and are often aggregated with MSM without consideration for their unique positions within sociocultural contexts. This study examined PrEP acceptability among trans women via three focus groups and nine individual interviews (total N = 30) in San Francisco. While knowledge of PrEP was low, interest was relatively high once participants were informed. Due to past negative healthcare experiences, ability to obtain PrEP from a trans-competent provider was cited as essential to PrEP uptake and adherence. Participants noted that PrEP could address situations in which trans women experience reduced power to negotiate safer sex, including sex work. Trans-specific barriers included lack of trans-inclusive marketing of PrEP, prioritisation of hormone use, and medical mistrust due to transphobia. Findings underscore the importance of disaggregating trans women from MSM in HIV prevention strategies to mitigate disparate risk among this highly vulnerable population. PMID:26963756

    In order to investigate the influence of processing parameters on the granularity distribution of superalloy powders during the atomization of plasma rotating electrode processing (PREP), in this paper FGH95 superalloy powders is prepared under different processing conditions by PREP and the influence of PREP processing parameters on the granularity distribution of FGH95 superalloy powders is discussed based on fractal geometry theory. The results show that with the increase of rotating velocity of the self-consuming electrode, the fractal dimension of the granularity distribution increases linearly, which results in the increase of the proportion of smaller powders. The change of interval between plasma gun and the self-consuming electrode has a little effect on the granularity distribution, also the fractal dimension of the granularity distribution changed a little correspondingly.

    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.

    Introduction Globally, transgender (“trans”) women are one of the key populations most disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is the newest and most promising biomedical HIV prevention intervention to date. This paper reviews relevant literature to describe the current state of the science and describes the potential role of PrEP among trans women, including a discussion of unique considerations for maximizing the impact of PrEP for this vulnerable population. Methods Available information, including but not limited to existing scientific literature, about trans women and PrEP was reviewed and critiqued based on author expertise, including PrEP clinical trials and rollout. Results To date, PrEP demonstration projects and clinical trials have largely excluded trans women, or have not included them in a meaningful way. Data collection strategies that fail to identify trans women in clinical trials and research further limit the ability to draw conclusions about trans women's unique needs and devise strategies to meet them. Gender-affirming providers and clinic environments are essential components of any sexual health programme that aims to serve trans women, as they will largely avoid settings that may result in stigmatizing encounters and threats to their identities. While there is currently no evidence to suggest drug-drug interactions between PrEP and commonly used feminizing hormone regimens, community concerns about potential interactions may limit interest in and uptake of PrEP among trans women. Conclusions In scaling up PrEP for trans women, it is essential to engage trans communities, utilize trans-inclusive research and marketing strategies and identify and/or train healthcare providers to provide gender-affirming healthcare to trans women, including transition-related care such as hormone provision. PrEP implementation guidelines must consider and address trans women's unique barriers and facilitators to uptake and

    Since the July 2012 approval by the FDA of emtricitabine/ tenofovir disoproxil fumarate (Truvada) for use as pre-exposure prophylaxis (PrEP) against HIV, its feasibility and acceptability has been under study. HIV-discordant couples are likely targets for PrEP but little is known about how this new prevention tool impacts relationships. We examined, among gay male couples, the acceptability of individual and partner use of PrEP and intentions to use condoms with primary and outside partners in the context of PrEP use. Data are from two independent samples of couples recruited in the San Francisco bay area and New York City-a qualitative one (N=48 couples) between March and November, 2011, and a quantitative one (N=171 couples) between June, 2012 and May, 2013. Data were categorized by couple HIV status and general linear models; chi-square tests of independence were used to examine condom-use intentions with primary and outside partners, by sexual risk profile, and race. Almost half of the HIV-negative couples felt PrEP was a good HIV prevention strategy for themselves and their partner. Over half reported that they would not change their current condom use if they or their partner were taking PrEP. However, approximately 30% of HIV-negative couples reported that they would stop using condoms or use them less with primary and outside partners if they were on PrEP or if their partner was on PrEP. A large percentage of couples view PrEP positively. However, to ensure safety for both partners, future programing must consider those who intend not to use condoms while on PrEP.

    Advances in biomedical interventions to prevent HIV offer great promise in reducing the number of new infections across sub- Saharan Africa, particularly among vulnerable populations such as female sex workers. Several recent trials testing pre-exposure prophylaxis (PrEP) have demonstrated efficacy, although others have been stopped early for futility. Given the importance and complexities of social and behavioural factors that influence biomedical approaches to prevention, we discuss several key areas of consideration moving forward, including trial participation, adherence strategies, social relationships, and the structural factors that shape PrEP interest, use, and potential effectiveness among female sex workers in sub-Saharan Africa. Our review highlights the importance of involving social scientists in clinical and community-based research on PrEP. We advocate for a shift away from a singular "re-medicalization" of the HIV epidemic to that of a "reintegration" of interdisciplinary approaches to prevention that could benefit female sex workers and other key populations at risk of acquiring HIV.

    The scope of this study was to understand the social representations of sexual violence and its relationship with adherence to the chemoprophylaxis protocol of HIV in young women and adolescents. Qualitative research was conducted based on the theory of social representations through recorded interviews with 13 female subjects aged between 12 and 23. It was observed that the social representations about sexual violence exerted a considerable influence on adherence to chemoprophylaxis treatment in the group. The individuals surveyed elaborated images in which the concern caused to the family, discomfort caused by the effects of drugs, change of routine, fear of getting sick, being stigmatized, anxiety and anger, appeared as constant elements, which can lead to the abandonment of treatment. Considering the influence of these representations on treatment, there is a need for greater attention of the health services in relation to these possibilities, and for resources to ensure care based on these different needs. In addition to investing in research into new drugs, it is necessary to invest in qualitative research, providing input for more appropriate care for patients. PMID:24897495

    Introduction Despite progress in scaling up antiretroviral treatment, HIV prevention strategies have not been successful in significantly curbing HIV incidence in Latin America. HIV prevention interventions need to be expanded to target the most affected key populations with a combination approach, including new high impact technologies. Oral pre-exposure prophylaxis (PrEP) is recommended as additional prevention choice for individuals at higher risk of infection and could become a cost-effective prevention tool. We discuss the barriers and solutions for a fair consideration of PrEP as part of combination HIV prevention strategies in Latin America. Discussion Although demonstration projects are ongoing or being planned in a number of countries, to date no Latin American country has implemented a public PrEP programme. The knowledge of policymakers about PrEP implementation needs to be strengthened, and programmatic guidance and cost estimate tools need to be developed to support adequate planning. Despite high levels of awareness among health providers, especially if engaged in HIV or key population care, willingness to prescribe PrEP is still low due to the lack of national policies and guidelines. Key populations, especially men who have sex with men, transgender women and sex workers, have been engaged in demonstration projects, and qualitative research shows high awareness and willingness to use PrEP, especially if accessible in the public sector for free or at affordable price. Concerns of safety, adherence, effectiveness and risk compensation need to be addressed through targeted social communication strategies to improve PrEP knowledge and stimulate demand. Alliance among policymakers, civil society and representatives from key populations, healthcare providers and researchers will be critical for the design and successful implementation of PrEP demonstration projects of locally adapted delivery models. The use of mechanisms of joint negotiation and

    Oral pre-exposure prophylaxis (PrEP) using the antiretroviral drug emtricitabine/tenofovir disoproxil fumarate (Truvada) has been shown to dramatically reduce the risk of HIV acquisition for women at higher risk of infection if taken daily. Understanding when and why women would intentionally stop using an efficacious oral PrEP drug within the context of their 'normal' daily lives is essential for delivering effective PrEP risk-reduction counselling. As part of a larger study, we conducted 60 qualitative interviews with women at higher risk of HIV in Bondo, Kenya, and Pretoria, South Africa. Participants charted their sexual contacts over the previous six months, indicated whether they would have taken PrEP if available and discussed whether and why they would have suspended PrEP use. Nearly all participants said they would have used PrEP in the previous six months; half indicated they would have suspended PrEP use at some point. Participants' reasons for an extended break from PrEP were related to partnership dynamics (e.g., perceived low risk of a stable partner) and phases of life (e.g., trying to conceive). Life events (e.g., holidays and travel) could prompt shorter breaks in PrEP use. These circumstances may or may not correspond to actual contexts of lower risk, highlighting the importance of tailored PrEP risk-reduction counselling. PMID:27093238

    Pre-B-cell leukemia homeobox (Pbx)-regulating protein-1 (Prep1) is a ubiquitous homeoprotein involved in early development, genomic stability, insulin sensitivity, and hematopoiesis. Previously we have shown that Prep1 is a haploinsufficient tumor suppressor that inhibits neoplastic transformation by competing with myeloid ecotropic integration site 1 for binding to the common heterodimeric partner Pbx1. Epithelial-mesenchymal transition (EMT) is controlled by complex networks of proinvasive transcription factors responsive to paracrine factors such as TGF-β. Here we show that, in addition to inhibiting primary tumor growth, PREP1 is a novel EMT inducer and prometastatic transcription factor. In human non-small cell lung cancer (NSCLC) cells, PREP1 overexpression is sufficient to trigger EMT, whereas PREP1 down-regulation inhibits the induction of EMT in response to TGF-β. PREP1 modulates the cellular sensitivity to TGF-β by inducing the small mothers against decapentaplegic homolog 3 (SMAD3) nuclear translocation through mechanisms dependent, at least in part, on PREP1-mediated transactivation of a regulatory element in the SMAD3 first intron. Along with the stabilization and accumulation of PBX1, PREP1 induces the expression of multiple activator protein 1 components including the proinvasive Fos-related antigen 1 (FRA-1) oncoprotein. Both FRA-1 and PBX1 are required for the mesenchymal changes triggered by PREP1 in lung tumor cells. Finally, we show that the PREP1-induced mesenchymal transformation correlates with significantly increased lung colonization by cells overexpressing PREP1. Accordingly, we have detected PREP1 accumulation in a large number of human brain metastases of various solid tumors, including NSCLC. These findings point to a novel role of the PREP1 homeoprotein in the control of the TGF-β pathway, EMT, and metastasis in NSCLC.

  18. PreP+07: improvements of a user friendly tool to preprocess and analyse microarray data

    2009-01-01

    Full Text Available Abstract Background Nowadays, microarray gene expression analysis is a widely used technology that scientists handle but whose final interpretation usually requires the participation of a specialist. The need for this participation is due to the requirement of some background in statistics that most users lack or have a very vague notion of. Moreover, programming skills could also be essential to analyse these data. An interactive, easy to use application seems therefore necessary to help researchers to extract full information from data and analyse them in a simple, powerful and confident way. Results PreP+07 is a standalone Windows XP application that presents a friendly interface for spot filtration, inter- and intra-slide normalization, duplicate resolution, dye-swapping, error removal and statistical analyses. Additionally, it contains two unique implementation of the procedures – double scan and Supervised Lowess-, a complete set of graphical representations – MA plot, RG plot, QQ plot, PP plot, PN plot – and can deal with many data formats, such as tabulated text, GenePix GPR and ArrayPRO. PreP+07 performance has been compared with the equivalent functions in Bioconductor using a tomato chip with 13056 spots. The number of differentially expressed genes considering p-values coming from the PreP+07 and Bioconductor Limma packages were statistically identical when the data set was only normalized; however, a slight variability was appreciated when the data was both normalized and scaled. Conclusion PreP+07 implementation provides a high degree of freedom in selecting and organizing a small set of widely used data processing protocols, and can handle many data formats. Its reliability has been proven so that a laboratory researcher can afford a statistical pre-processing of his/her microarray results and obtain a list of differentially expressed genes using PreP+07 without any programming skills. All of this gives support to scientists

    Full Text Available Introduction: Young key populations, defined in this article as men who have sex with men, transgender persons, people who sell sex and people who inject drugs, are at particularly high risk for HIV. Due to the often marginalized and sometimes criminalized status of young people who identify as members of key populations, there is a need for HIV prevention packages that account for the unique and challenging circumstances they face. Pre-exposure prophylaxis (PrEP is likely to become an important element of combination prevention for many young key populations. Objective: In this paper, we discuss important challenges to HIV prevention among young key populations, identify key components of a tailored combination prevention package for this population and examine the role of PrEP in these prevention packages. Methods: We conducted a comprehensive review of the evidence to date on prevention strategies, challenges to prevention and combination prevention packages for young key populations. We focused specifically on the role of PrEP in these prevention packages and on young people under the age of 24, and 18 in particular. Results and discussion: Combination prevention packages that include effective, acceptable and scalable behavioural, structural and biologic interventions are needed for all key populations to prevent new HIV infections. Interventions in these packages should meaningfully involve beneficiaries in the design and implementation of the intervention, and take into account the context in which the intervention is being delivered to thoughtfully address issues of stigma and discrimination. These interventions will likely be most effective if implemented in conjunction with strategies to facilitate an enabling environment, including increasing access to HIV testing and health services for PrEP and other prevention strategies, decriminalizing key populations’ practices, increasing access to prevention and care, reducing stigma and

    Full Text Available Professional bodies in the UK (BASHH/BHIVA do not currently recommended pre-exposure prophylaxis (PREP to prevent HIV aquisition for men who have sex with men (MSM [1]. Conversely, although Federal Drug Administration approval is awaited, the Centers for Disease Control (CDC have issued clinicians in the USA with interim guidance to facilitate PREP prescriptions [2]. Increasingly patients search the internet for information on HIV treatment, but disparate international policy can lead to confusing patient messages. This study was conducted to systematically assess the quality of internet information available to patients in the UK about PREP. More than 90% of internet searches in the UK are performed using ‘Google.co.uk’ and ‘Bing’ [3]. Using pre-specified criteria, we reviewed the first 100 hits retrieved from each search engine when the following searches were performed: [“HIV pre-exposure prophylaxis”]; [“HIV PREP”]; [“HIV PREP guidelines”]; [“HIV PREP guidelines UK”]; [“truvada prophylaxis HIV”]. Of 172 unique websites identified, 124 websites were active at the time of the review (July 2012. 33 websites were links to academic journals including commentaries and clinical trials, not intended to specifically provide patient information; 5 were internet portals directing users to alternative sites and 10 websites contained no information about PREP. Of the remaining 76 websites, 28 were written by medical professionals and 48 were written by journalists, where 7/48 (15% were individual blogs. 64/76 (84% contained a definition of PREP; 63/76 (83% discussed the rationale and 58/76 (76% reported efficacy data. Advantages and disadvantages of PREP were presented in 56/76 (74% and 41/76 (54% of websites respectively. Only 21/76 (28% of sites referenced existing national guidelines (CDC/BASHH.

    Full Text Available OBJECTIVE: We aimed to understand the attitudes, preferences and acceptance of oral and parenteral PrEP among men who have sex with men (MSM in Thailand. BACKGROUND: Pre-exposure prophylaxis (PrEP, the use of antiretrovirals to prevent HIV acquisition, has shown promising results in recent trials. To assess the potential impact of this new HIV prevention method, in addition to efficacy data, we need to understand which psychosocial factors are likely to determine its uptake among members of potential user groups. METHODS AND FINDINGS: Surveys of willingness to use PrEP products were administered to MSM. Spearman's rank tests were used to uncover associations between questionnaire items. Mann-Whitney tests were performed to ascertain differences between groups. Conjoint analysis was used to examine the attitudes and preferences of MSM towards PrEP attributes. Most participants were willing to consider taking PrEP (39.2% "yes, definitely" and 49.2% "yes, probably" and perceived PrEP as giving them new possibilities in their lives (38.5% "a lot of hope" and 55.8% "some hope", even after being instructed of potential side effects and costs. HIV testing was considered the most important attribute and a daily pill and longer lasting injection in the arm were the preferred routes of administration. CONCLUSIONS: Despite its multiple challenges, MSM in Thailand would be willing to take PrEP, even if they had to experience inconvenience and expense. If PrEP were to be implemented in Thailand, our findings show that its uptake could be considerable.

  4. Prep1 (pKnox1 regulates mouse embryonic HSC cycling and self-renewal affecting the Stat1-Sca1 IFN-dependent pathway.

    Directory of Open Access Journals (Sweden)

    Livia Modica

    Full Text Available A hypomorphic Prep1 mutation results in embryonic lethality at late gestation with a pleiotropic embryonic phenotype that includes defects in all hematopoietic lineages. Reduced functionality of the hematopoietic stem cells (HSCs compartment might be responsible for the hematopoietic phenotype observed at mid-gestation. In this paper we demonstrate that Prep1 regulates the number of HSCs in fetal livers (FLs, their clonogenic potential and their ability to de novo generate the hematopoietic system in ablated hosts. Furthermore, we show that Prep1 controls the self-renewal ability of the FL HSC compartment as demonstrated by serial transplantation experiments. The premature exhaustion of Prep1 mutant HSCs correlates with the reduced quiescent stem cell pool thus suggesting that Prep1 regulates the self-renewal ability by controlling the quiescence/proliferation balance. Finally, we show that in FL HSCs Prep1 absence induces the interferon signaling pathway leading to premature cycling and exhaustion of fetal HSCs.

    Full Text Available Abstract Background Bipolar disorder (BD is a major psychiatric condition that commonly requires prophylactic and episodic treatment. Lithium (Li has been used for over 40 years now as an effective prophylactic agent. Response to Li treatment seems to be, at least in part, genetically determined. Although we ignore how Li specifically prevents mood episodes, it has previously been suggested that Li exerts an effect on the phosphoinositide pathway, and more recently, it has been proposed that Li may modulate prolyl endopeptidase (PREP. Methods In this study we carried out an association study looking at the PREP gene, located on ch 6q22. Five intronic single nucleotide polymorphisms (SNP, three coding SNPs and one SNP in the 5' UTR were investigated for their frequency in a BD sample of 180 excellent Li responders, 69 Li nonresponders and 126 controls. Genotyping was carried out using the SNaPshot reaction from Applied Biosystems, which is a modified fluorescent single base pair extension procedure. Results Following correction for multiple testing, no significant genotypic, allelic or estimated haplotypic differences were found between responders and nonresponders or between BD patients and controls. Conclusion PREP is an interesting candidate gene to investigate in genetic studies of BD, but our findings do not support the hypothesis that genetic variation in this gene plays a major role in the etiology of BD or Li response.

    Previous literature has suggested that examining Twitter messages can be productive for studying how the public shares and spreads health information on social media. Preexposure prophylaxis (PrEP) is a promising approach to HIV prevention, yet there are many issues that may influence its effective implementation. This study examined social representations of PrEP on Twitter. One thousand four hundred and thirty-five Tweets were collected and 774 English Tweets were content-analyzed to explore propagation of various issues around daily oral PrEP, as well as characteristics of the sources of those Tweets. We also examined how Twitter message content influenced information propagation. Our findings revealed that PrEP-related information on Twitter covered a wide range of issues, and individual users constituted the majority of the Tweet creators among all the sources, including news media, nonprofit and academic groups, and commercial entities. Using Poisson regression, we also found that a Tweet's affective tone was a significant predictor of message propagation frequency. Implications for health practitioners are discussed. PMID:26756069

    Strategic framing of public messages about HIV pre-exposure prophylaxis (PrEP) may influence public support for policies and programs affecting access. This survey study examined how public attitudes toward PrEP differed based on the social group PrEP was described as benefiting ("beneficiary") and the moderating effect of prejudice. Members of the general public (n = 154) recruited online were randomly assigned to three beneficiary conditions: general population, gay men, or Black gay men. All participants received identical PrEP background information before completing measures of PrEP attitudes (specifying beneficiary), racism, and heterosexism. Despite anticipating greater PrEP adherence among gay men and Black gay men and perceiving PrEP as especially beneficial to the latter, participants expressed lower support for policies/programs making PrEP affordable for these groups vs. the general population. This disparity in support was stronger among participants reporting greater prejudice. Inclusive framing of PrEP in public discourse may prevent prejudice from undermining implementation efforts.

    Pre-exposure prophylaxis (PrEP), the antiretroviral treatment regimen for HIV-negative people at high risk of acquiring HIV, has demonstrated efficacy across clinical trials in several patient populations. The Centers for Disease Control (CDC) have released detailed guidelines to aid providers in prescribing PrEP for their high-risk patients, including men who have sex with men (MSM), high-risk heterosexuals, and injection drug users (IDUs). Given that much attention in PrEP has focused on MSM patients, the present study used an online survey to assess factors involved in HIV care providers' (n = 363) decisions about prescribing PrEP, along with their willingness to prescribe PrEP to patients from various risk populations (e.g., MSM, heterosexuals, IDUs). The efficacy of PrEP was an important factor in providers' decisions about prescribing PrEP, as were considerations about patients' adherence to the regimen, regular follow-up for care, and medication costs. This survey's findings also suggest that providers' willingness to prescribe PrEP varies by patient group, with providers most willing to initiate the regimen with MSM who have an HIV-positive partner, and least willing to prescribe to high-risk heterosexuals or IDUs. In the context of the current CDC recommendations for PrEP that include MSM, heterosexuals, and IDUs, examining providers' rationales for and barriers against supporting this HIV prevention strategy across patient groups merits further attention.

    The double-blind phase of the randomized ANRS IPERGAY trial, evaluating sexual activity-based oral HIV pre-exposure prophylaxis (PrEP), was conducted among high-risk men who have sex with men (MSM). Results showed an 86% (95% CI: 40-98) relative reduction in HIV incidence among participants with tenofovir disoproxil fumarate-emtricitabine vs. placebo. The present pooled analysis aimed to analyze (i) participants' adherence to the prescribed treatment and/or condom use during sexual intercourse and (ii) sexual behavior during the double-blind phase of the study. Four hundred MSM were enrolled in the trial. Every 2 months they completed online questionnaires collecting sexual behavior and PrEP adherence data regarding their most recent sexual intercourse. A total of 2232 questionnaires (M0-M24) were analyzed. Changes over time were evaluated using a mixed model accounting for multiple measures. Irrespective of sexual partner and practice type, on average, 42.6% (min: 32.1-max: 45.8%) reported PrEP use only during their most recent episode of sexual intercourse; 29% (22.9-35.6%) reported both PrEP and condom use; 11.7% (7.2-18.9%) reported condom-use only, and 16.7% (10.8-29.6%) reported no PrEP or condom use with no significant change during the study. Scheduled (i.e., correct) PrEP use was reported on average by 59.0% (47.2-68.5%) of those reporting PrEP use during their most recent sexual intercourse. Overall, 70.3% (65.3-79.4%) and 69.3% (58.3-75.4%) of participants reported, respectively, condomless anal and condomless receptive anal intercourse during their most recent sexual encounter without significant change during follow-up. Overall, on average 83.3% (min: 70.4-max: 89.2%) of participants protected themselves by PrEP intake or condom use or both during the trial, and no increase in at-risk sexual practices was observed. None of these indicators showed significant trend during the follow-up, although we found a tendency toward decrease (p = .19) of the

    ChemPrep was developed to be a stand-alone preparatory short-course to help students succeed in general chemistry. It is Web-based and delivered using the OWL system. Students reported that the ChemPrep materials (short information pages, parameterized questions with detailed feedback, tutorials, and answers to questions through the OWL message system) permitted them to work independently without the need for textbook or lecture. On average, students who completed ChemPrep had higher grades in the subsequent GenChem, Nursing, and Honors chemistry courses, with a greater percentage achieving a grade of C- or higher. Participation in ChemPrep was voluntary, and more women than men responded. Students in the Honors course enrolled in ChemPrep in higher percentages than students in GenChem and Nursing. SAT and departmental math placement exam scores were used as proxy measures of prior achievement and ability. Based on these, Honors chemistry ChemPrep users were on par with their peers but performed better in the course than non-users. In GenChem and Nursing chemistry courses, ChemPrep helped students of high prior achievement and ability perform better than their achievement scores would predict. Weaker or less motivated students did not respond to the voluntary offerings of ChemPrep in the same numbers as stronger or more motivated students, and we are seeking alternate ways to reach this population.

    Oral HIV pre-exposure prophylaxis (PrEP) is a promising new biomedical prevention approach in which HIV-negative individuals are provided with daily oral antiretroviral medication for the primary prevention of HIV-1. Several clinical trials have demonstrated efficacy of oral PrEP for HIV prevention among groups at high risk for HIV, with adherence closely associated with level of risk reduction. In the United States (US), three groups have been prioritized for initial implementation of PrEP-injection drug users, men who have sex with men at substantial risk for HIV, and HIV-negative partners within serodiscordant heterosexual couples. Numerous demonstration projects involving PrEP implementation among MSM are underway, but relatively little research has been devoted to study PrEP implementation in HIV-serodiscordant heterosexual couples in the US. Such couples face a unique set of challenges to PrEP implementation at the individual, couple, and provider level with regard to PrEP uptake and maintenance, adherence, safety and toxicity, clinical monitoring, and sexual risk behavior. Oral PrEP also provides new opportunities for serodiscordant couples and healthcare providers for primary prevention and reproductive health. This article provides a review of the critical issues, challenges, and opportunities involved in the implementation of oral PrEP among HIV-serodiscordant heterosexual couples in the US.

    The technology to collect brain imaging and physiological measures has become portable and ubiquitous, opening the possibility of large-scale analysis of real-world human imaging. By its nature, such data is large and complex, making automated processing essential. This paper shows how lack of attention to the very early stages of an EEG preprocessing pipeline can reduce the signal-to-noise ratio and introduce unwanted artifacts into the data, particularly for computations done in single precision. We demonstrate that ordinary average referencing improves the signal-to-noise ratio, but that noisy channels can contaminate the results. We also show that identification of noisy channels depends on the reference and examine the complex interaction of filtering, noisy channel identification, and referencing. We introduce a multi-stage robust referencing scheme to deal with the noisy channel-reference interaction. We propose a standardized early-stage EEG processing pipeline (PREP) and discuss the application of the pipeline to more than 600 EEG datasets. The pipeline includes an automatically generated report for each dataset processed. Users can download the PREP pipeline as a freely available MATLAB library from http://eegstudy.org/prepcode.

    The 1997 Houston Pre-Freshman Enrichment Program (PREP) was conducted at the campus of the University of Houston-Downtown from June 9 to July 25, 1997. Program participants were recruited from the Greater Houston Area. All participants were identified as high-achieving students with an interest in learning about the engineering and science professions. The goal of the program was to better prepare our pre-college youth prior to entering college as mathematics, science and engineering majors. The program participants were middle school and high school students from the Aldine, Alief, Channel View, Clear Creek, Cypress-Fairbanks, Fort Bend, Galena Park, Houston, Humble, Katy, Klein, North Forest, Pasadena, Private, and Spring Branch Independent School Districts. Of the 194 students starting the program, 165 students were from economically and socially disadvantage groups under-represented in the engineering and science professions, and 118 of the 194 were women. Our First Year group for 1997 composed of 96% minority and women students. Second and Third Year students combined were 96% minority or women. With financial support from the Center for Computational Sciences and Advanced Distributed Simulation, the Fourth Year Program was added to PREP this year. Twelve students completed the program (83% minority or women).

    Optimizing access to HIV pre-exposure prophylaxis (PrEP), an evidence-based HIV prevention resource, requires expanding healthcare providers' adoption of PrEP into clinical practice. This qualitative study explored PrEP providers' firsthand experiences relative to six commonly-cited barriers to prescription-financial coverage, implementation logistics, eligibility determination, adherence concerns, side effects, and anticipated behavior change (risk compensation)-as well as their recommendations for training PrEP-inexperienced providers. U.S.-based PrEP providers were recruited via direct outreach and referral from colleagues and other participants (2014-2015). One-on-one interviews were conducted in person or by phone, transcribed, and analyzed. The sample (n = 18) primarily practiced in the Northeastern (67%) or Southern (22%) U.S. Nearly all (94%) were medical doctors (MDs), most of whom self-identified as infectious disease specialists. Prior experience prescribing PrEP ranged from 2 to 325 patients. Overall, providers reported favorable experiences with PrEP implementation and indicated that commonly anticipated problems were minimal or manageable. PrEP was covered via insurance or other programs for most patients; however, pre-authorization requirements, laboratory/service provision costs, and high deductibles sometimes presented challenges. Various models of PrEP care and coordination with other providers were utilized, with several providers highlighting the value of clinical staff support. Eligibility was determined through joint decision-making with patients; CDC guidelines were commonly referenced but not considered absolute. Patient adherence was variable, with particularly strong adherence noted among patients who had actively sought PrEP (self-referred). Providers observed minimal adverse effects or increases in risk behavior. However, they identified several barriers with respect to accessing and engaging PrEP candidates. Providers offered a wide

    Between 2004 and 2005, the first multi-sited clinical trial tested whether an existing, marketed antiretroviral drug, Tenofovir (TDF), could prevent HIV transmission. Referred to as pre-exposure prophylaxis (PrEP), most of these trial sites prematurely closed down. Two sites located in Cambodia and Cameroon received international media attention. But little attention was drawn to sites in Malawi and Nigeria, where university ethicists and research scientists extensively debated PrEP. This article focuses on events that took place in Malawi where there was a prolonged dispute over the scientific rationales of PrEP and not trial specific ethics referred to as 'bioethics'. Specifically, the article discusses debates pertaining to three PrEP trial protocols that were refused ethics approval in Malawi between 2004 and 2009. It is argued that HIV science debates in Malawi are embedded in postcolonial politics--geopolitical histories and state and household economic dispossessions that have created the structural possibilities for Malawi to become an offshore destination for HIV clinical research. As such, ethics in this case does not pertain to trial or bioethical 'failures'. Rather, ethics is located at the scale of imperial relations that give rise to multiple, often invisible, research concerns and constraints.

  19. A qualitative study of provider thoughts on implementing pre-exposure prophylaxis (PrEP in clinical settings to prevent HIV infection.

    Full Text Available BACKGROUND: A recent clinical trial demonstrated that a daily dose tenofovir disoproxil fumarate and emtricitabrine (TDF-FTC can reduce HIV acquisition among men who have sex with men (MSM and transgender (TG women by 44%, and up to 90% if taken daily. We explored how medical and service providers understand research results and plan to develop clinical protocols to prescribe, support and monitor adherence for patients on PrEP in the United States. METHODS: Using referrals from our community collaborators and snowball sampling, we recruited 22 healthcare providers in San Francisco, Oakland, and Los Angeles for in-depth interviews from May-December 2011. The providers included primary care physicians seeing high numbers of MSM and TG women, HIV specialists, community health clinic providers, and public health officials. We analyzed interviews thematically to produce recommendations for setting policy around implementing PrEP. Interview topics included: assessing clinician impressions of PrEP and CDC guidance, considerations of cost, office capacity, dosing schedules, and following patients over time. RESULTS: Little or no demand for PrEP from patients was reported at the time of the interviews. Providers did not agree on the most appropriate patients for PrEP and believed that current models of care, which do not involve routine frequent office visits, were not well suited for prescribing PrEP. Providers detailed the need to build capacity and were concerned about monitoring side effects and adherence. PrEP was seen as potentially having impact on the epidemic but providers also noted that community education campaigns needed to be tailored to effectively reach specific vulnerable populations. CONCLUSIONS: While PrEP may be a novel and clinically compelling prevention intervention for MSM and TG women, it raises a number of important implementation challenges that would need to be addressed. Nonetheless, most providers expressed optimism that

  20. Analytic review of modeling studies of ARV Based PrEP interventions reveals strong influence of drug-resistance assumptions on the population-level effectiveness.

    Directory of Open Access Journals (Sweden)

    Dobromir Dimitrov

    Full Text Available BACKGROUND: Four clinical trials have shown that oral and topical pre-exposure prophylaxis (PrEP based on tenofovir may be effective in preventing HIV transmission. The expected reduction in HIV transmission and the projected prevalence of drug resistance due to PrEP use vary significantly across modeling studies as a result of the broad spectrum of assumptions employed. Our goal is to quantify the influence of drug resistance assumptions on the predicted population-level impact of PrEP. METHODS: All modeling studies which evaluate the impact of oral or topical PrEP are reviewed and key assumptions regarding mechanisms of generation and spread of drug-resistant HIV are identified. A dynamic model of the HIV epidemic is developed to assess and compare the impact of oral PrEP using resistance assumptions extracted from published studies. The benefits and risks associated with ten years of PrEP use are evaluated under identical epidemic, behavioral and intervention conditions in terms of cumulative fractions of new HIV infections prevented, resistance prevalence among those infected with HIV, and fractions of infections in which resistance is transmitted. RESULTS: Published models demonstrate enormous variability in resistance-generating assumptions and uncertainty in parameter values. Depending on which resistance parameterization is used, a resistance prevalence between 2% and 44% may be expected if 50% efficacious oral PrEP is used consistently by 50% of the population over ten years. We estimated that resistance may be responsible for up to a 10% reduction or up to a 30% contribution to the fraction of prevented infections predicted in different studies. CONCLUSIONS: Resistance assumptions used in published studies have a strong influence on the projected impact of PrEP. Modelers and virologists should collaborate toward clarifying the set of resistance assumptions biologically relevant to the PrEP products which are already in use or soon to

    Full Text Available Abstract Objective Since the introduction of the liquid-based ThinPrep testing in 1996, most cytology laboratories across the country have adopted the liquid-based cytology (LBC for Pap test screening. Subsequent to wide-spread adoption of the ThinPrep Pap test, the ThinPrep Imaging System (TIS Cytyc Corp, Marlborough, MA was introduced to improve the accuracy and efficiency of screening interpretation. We report our initial experience with the TIS at Magee Women's Hospital. We introduced the TIS in December 2004. Methods The imager assisted Pap test results over the first 12 months (December 2004 to December 2005 of implementation were reviewed and analyzed. Our implementation protocol included each cytotechnologist manually prescreening 200 negative slides to gain experience with the imager slides and serve as a quality check for the TIS. We re-screened 3400 slides (200 slides each for 17 cytotechnologists manually which were initially determined to be negative using the TIS. 104,457 Pap tests were imaged on the TIS. 95,899 manually screened Pap tests, 12 months prior to the introduction of the TIS (December 2003–November 2004 are taken as the historic control group for our study. Results The mean ASC-US rate employing the automated imager was 8.70% [9088/104,457]. The mean LSIL detection rate was 4.22% [4409/104,457]. The imager did not miss any detectible high-grade lesions during these months, with a HSIL (+ detection rate of 0.68% in comparison to 0.60% by manual screening confirmed by follow-up biopsies. The difference is statistically significant with a p value of 0.022. The definition of false negative rate for purposes of this study is calculated as the number of false negative cases identified out of number of negatives re-screened. The TIS false negative rate was estimated at 0.012% [4/3400]. Conclusion The overall performance of the TIS in our lab appears to be highly satisfactory in terms of improving sensitivity in screening

  2. PREPS2 - a PC-based computer program for performing economic analysis of capital projects

    International Nuclear Information System (INIS)

    In these times of increased spending to finance new capacity and to meet clean air act legislation, many electric utilities are giving a high priority to controlling capital expenditures at existing generating facilities. Determining the level of capital expenditures which are economically justified is very difficult; units which have higher capacity factors are worth more to the utility. Therefore, the utility can more readily justify higher capital expenditures to improve or maintain reliability and heat rate than on units with lower capacity factors. This paper describes a PC-based computer program (PREPS2) which performs an economic analysis of individual capital projects. The program incorporates tables which describe the worth to the system of making improvements in each unit. This computer program is currently being used by the six Southern Company operating companies to evaluate all production capital projects over $50,000. Approximately 500 projects representing about $300 million are being analyzed each year

    Rehabilitation of patients with anterior conoid teeth may present a challenge for the clinician, especially when trying to mimic the nature with composite resins. This clinical report exemplifies how a patient with conoid upper lateral incisors was rehabilitated with minimally invasive adhesive restorations. Following diagnostic wax-up and cosmetic mock-up, no-prep veneers and ceramic fragments (partial veneers) were constructed with feldspathic porcelain. This restorative material presents excellent reproduction of the optical properties of the dental structure, especially at minimal thicknesses. In this paper, the details about the treatment are described. A very pleasing outcome was achieved, confirming that minimally invasive adhesive restorations are an excellent option for situations in which the dental elements are healthy, and can be modified exclusively by adding material and the patient does not want to suffer any wear on the teeth.

    Existing yeast genomic DNA extraction methods are not ideally suited to extensive screening of colonies by PCR, due to being too lengthy, too laborious or yielding poor quality DNA and inconsistent results. We developed the GC prep method as a solution to this problem. Yeast cells from colonies or liquid cultures are lysed by vortex mixing with glass beads and then boiled in the presence of a metal chelating resin. In around 12 minutes, multiple samples can be processed to extract high yields of genomic DNA. These preparations perform as effectively in PCR screening as DNA purified by organic solvent methods, are stable for up to 1 year at room temperature and can be used as the template for PCR amplification of fragments of at least 8 kb.

    Haskell, Deborah Harris

    As teachers implement the National Science Education Standards (NRC, 1996) many have to reform the instructional methods they have used throughout their careers. This case study examines the transformation of Laurie, a 20-year teacher, during her first year of change from a "traditional" textbook/lecture style of teaching to a facilitator of an inquiry-based classroom. Implementing change requires not only pedagogical expertise, but also the belief that the modifications can be made and that the outcomes are significant. Using Bandura's social cognitive theory as a framework, changes in Laurie's self-efficacy, outcome expectancy, and motivation are followed throughout the transition. During her first year of change, Laurie used worksheets, small group activities, and guided inquiry activities, all strategies in which she had high self-efficacy and experienced positive student outcomes. She rarely used class forums, authentic assessment, and formative assessment. Factors that influenced her change were experiential professional development opportunities that allowed her to practice inquiry-based techniques, a change in her teaching environment from college prep chemistry to tech prep biology, autonomy regarding classroom decisions, and reflective decision making as she learned through experience. Using a standards-based biology textbook increased her self-efficacy toward using inquiry-based practices. The textbook format of embedding text in activities rather than adding activities to the text resulted in an increase of the number and frequency of activities done. Facilitating the textbook's Guided Inquiries and Extended Inquiries helped Laurie gain experience with inquiry-based methods. She also realized that when building from the students' concrete experiences, her students were able to attain higher-level thinking skills. The study revealed six factors contributing to Laurie's change process: (a) experiential professional development, (b) motivation for change

    The 1996 Houston Pre-freshman Enrichment Program (PREP) was conducted on the campus of the University of Houston-Downtown from June 10 to August 1, 1996. Program Participants were recruited from the Greater Houston area. All participants were identified as high achieving students with an interest in learning about the engineering and science professions. The goal of the program was to better prepare our pre-college youth prior to entering college as mathematics, science and engineering majors. The program participants were middle school and high school students from the Aldine, Alief, Channel View, Crockett, Cypress-Fairbanks, Fort Bend, Galena Park, Houston, Humble, Katy, Klein, North Forest, Pasadena, Private, and Spring Branch Independent School Districts. Of the 197 students starting the program, 170 completed, 142 students were from economically and socially disadvantage groups underrepresented in the engineering and science professions, and 121 of the 197 were female. Our First Year group for 1996 composed of 96% minority and women students. Our Second and Third Year students were 100% and 93.75% minority or women respectively. This gave an overall minority and female population of 93.75%. This year, special efforts were again made to recruit students from minority groups, which caused a significant increase in qualified applicants. However, due to space limitations, 140 applicants were rejected. Investigative and discovery learning were key elements of PREP. The academic components of the program included Algebraic Structures, Engineering, Introduction to Computer Science, Introduction to Physics, Logic and Its Application to Mathematics, Probability and Statistics, Problem Solving Seminar using computers and PLATO software, SAT Preparatory Seminars, and Technical Writing.

    Background Pre-exposure prophylaxis (PrEP) has been proven to reduce HIV acquisition in men who have sex with men and transgender women (MSM/TGW). For maximal impact, PrEP should be targeted to subpopulations accounting for the largest proportion of infections (population attributable fraction, PAF) and for whom the number needed to treat (NNT) to prevent infection is lowest. Methods The iPrEx study was a randomized controlled efficacy trial of tenofovir-disoproxil-fumarate/emtricitabine PrEP in 2499 MSM/TGW on 4 continents. We calculated the association between demographic and risk behavior during screening with subsequent seroconversion among placebo recipients using a Poisson model, and the PAF and NNT for risk behavior subgroups. Findings Of 1248 placebo participants enrolled, 83 became HIV infected in follow-up. Participants reporting non-condom receptive anal intercourse (ncRAI) seroconverted significantly more often than MSM/TGW reporting no condomless anal sex (adjusted hazard ratio (AHR) 5·11, 95% CI 1·55-16·79). The overall PAF for MSM/TGW reporting ncRAI was 64% (prevalence=60%). Most of this risk came from ncRAI with unknown serostatus partners (PAF 53%, prevalence=54%, AHR 4·76); in contrast, the PAF for ncRAI with an HIV positive partner, an uncommon practice, was only 1% (prevalence 1%, AHR=7·11). The overall NNT per year for the cohort was 62 (95% CI 44-147). NNTs were lower for MSM/TGW self-reporting ncRAI, cocaine use, or a sexually transmitted infection (NNT= 36, 12, and 41 respectively). Having a single partner or non-condom insertive anal sex had the highest NNTs. Interpretation PrEP may be most effective at a population level if targeted toward MSM/TGW reporting ncRAI, even with partners perceived to be HIV negative. Substance use history and testing for STIs may also inform individual decisions to start PrEP. Considering PAF and NNT can aid in discussing the benefits and risks of PrEP with MSM/TGW.

    A case of an acute reversible visual loss in a 10-year-old child who was on mefloquine prophylaxis, and was treated with artesunate-amodiaquine for an acute febrile illness diagnosed clinically as uncomplicated malaria, is reported. On admission the patient could not perceive light and had bilateral papilloedema. She was treated with dexamethasone and recovered her sight gradually over a 21-day period. There has been no previous report to our knowledge, of an association between acute visual loss and mefloquine, amodiaquine, or artesunate in the published literature, even though mefloquine is associated with blurring of vision, and antimalarials of the quinoline class have been associated with retinopathy (during long term use). While causality is difficult to ascribe in this case, it may be prudent to avoid the use of quinoline-based antimalarials for treating acute malaria in travelers taking mefloquine prophylaxis, because information on the safety of concurrent use of artemisinin combination therapies and mefloquine, or other recommended prophylactic regimens, is limited.

    Full Text Available In many settings, interventions targeting female sex workers (FSWs could significantly reduce the overall transmission of HIV. To understand the role HIV pre-exposure prophylaxis (PrEP could play in controlling HIV transmission amongst FSWs, it is important to understand how its impact compares with scaling-up condom use—one of the proven HIV prevention strategies for FSWs. It is important to remember that condoms also have other benefits such as reducing the incidence of sexually transmitted infections and preventing pregnancy. A dynamic deterministic model of HIV transmission amongst FSWs, their clients and other male partners (termed ‘pimps’ was used to compare the protection provided by PrEP for HIV-negative FSWs with FSWs increasing their condom use with clients and/or pimps. For different HIV prevalence scenarios, levels of pimp interaction, and baseline condom use, we estimated the coverage of PrEP that gives the same reduction in endemic FSW HIV prevalence or HIV infections averted as different increases in condom use. To achieve the same impact on FSW HIV prevalence as increasing condom use by 1%, the coverage of PrEP has to increase by >2%. The relative impact of PrEP increases for scenarios where pimps contribute to HIV transmission, but not greatly, and decreases with higher baseline condom use. In terms of HIV infections averted over 10 years, the relative impact of PrEP compared to condoms was reduced, with a >3% increase in PrEP coverage achieving the same impact as a 1% increase in condom use. Condom promotion interventions should remain the mainstay HIV prevention strategy for FSWs, with PrEP only being implemented once condom interventions have been maximised or to fill prevention gaps where condoms cannot be used.

    OBJECTIVE To investigate the available parameters in gynecological screening for cervical lesions by liquid-based cytology technology (ThinPrep Cytology Test, TCT) and The Bethesda System (TBS), also with computer image analysis. METHODS With application of the image analysis system, all grades of cervical lesion cells were detected quantitatively and sorted in atypical squamous cells of undetermined significance (ASCUS), atypical squamous cells-cannot exclude HSIL (ASC-H), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL) and cervical squamous cell carcinoma (SCC) with the mean optical density (MOD), average grey (AG), positive units (PU), and nucleus to cytoplasmic ratio (N:C). Differences between each group of cells were compared and analyzed statistically.RESULTS Apart from four stereologic parameters in LSIL and HSIL groups there were no differences among them, in the other groups, there was statistically significant in differences between MOD, AG and PU values. Differences between them in the ratio of nucleus to cytoplasm were highly statistically signifi cant. CONCLUSION Stereological indexes may serve as a screening tool for cervical lesions. The image analysis system is expected to become a new means of cytological assisted diagnosis.

  16. A retrospective comparison of smart prep and test bolus multi-detector CT pulmonary angiography protocols

    International Nuclear Information System (INIS)

    Optimal arterial opacification is crucial in imaging the pulmonary arteries using computed tomography (CT). This poses the challenge of precisely timing data acquisition to coincide with the transit of the contrast bolus through the pulmonary vasculature. The aim of this quality assurance exercise was to investigate if a change in CT pulmonary angiography (CTPA) scanning protocol resulted in improved opacification of the pulmonary arteries. Comparison was made between the smart prep protocol (SPP) and the test bolus protocol (TBP) for opacification in the pulmonary trunk. A total of 160 CTPA examinations (80 using each protocol) performed between January 2010 and February 2011 were assessed retrospectively. CT attenuation coefficients were measured in Hounsfield Units (HU) using regions of interest at the level of the pulmonary trunk. The average pixel value, standard deviation (SD), maximum, and minimum were recorded. For each of these variables a mean value was then calculated and compared for these two CTPA protocols. Minimum opacification of 200 HU was achieved in 98% of the TBP sample but only 90% of the SPP sample. The average CT attenuation over the pulmonary trunk for the SPP was 329 (SD = ±21) HU, whereas for the TBP it was 396 (SD = ±22) HU (P = 0.0017). The TBP also recorded higher maximum (P = 0.0024) and minimum (P = 0.0039) levels of opacification. This study has found that a TBP resulted in significantly better opacification of the pulmonary trunk than the SPP

Despite the eradication efforts, malaria still remains one of the most significant causes of morbidity and mortality in tropical and subtropical regions. Many different antimalarial regimens are used , however resistance is emerging to many of themPurpose: This critical review was conducted, in order to respond to the following questions. A Which antimalarial regimen is most effective? B Which regimen is the safest for travelers in endemic regions? C Which regimen is best tolerated?Methodology: The literature research was conducted through the Internet. The Medline and Cinahl databases were used, as well as the search engines google, altavista and lycos. The research included articles that described clinical trials. The material was selected based on the aforementioned research questions and the chronological time limits.Results: Atovaquone/proguanil, tafenoquine, primaquine were the most effective regimens. Tafenoquine, as well as, primaquine have been related to hemolytic events in individuals with G6PD deficiency, gastrointestinal disorders, backache and flue-like syndrome. Doxycycline and mefloquine were related to gastrointestinal and neurological disorders. Those were the less tolerated regimens.Conclusions: Atovaquone/proguanil, tafenoquine, primaquine were the most effective regimens. As far as safety is concerned, tafenoquine and primaquine should not be prescribed to individuals with G6PD deficiency. All the regimens were considered well tolerated, however, in doxycycline and mefloquine trials were the most withdrawals due to adverse effects.

    Full Text Available Human immune-virus (HIV infection is the most significant risk factor for progression of latent mycobacterium tuberculosis (MTB infection to active tuberculosis. Tuberculosis reactivation among human immunodeficiency virus (HIV infected cases can be prevented by anti tubercular chemoprophylaxis. This randomized controlled study compared the efficacy of 2 months of daily rifampicin and pyrazinamide and 6 months of daily rifampicin and isoniazid drug regimes in preventing active tuberculosis in HIV seropositives. It is observed that 2 months of daily rifampicin in combination with pyrazinamide is not only efficacious as that of 6 months of daily rifampicin and isoniazid combination in preventing active tuberculosis in HIV seropositives but has the advantage of better compliance, lesser side effects and prolonged post prophylactic preventive effect.

    Chemical synthesis methods are being developed as a future source of PZT 95/5 powder for neutron generator voltage bar applications. Laboratory-scale powder processes were established to produce PZT billets from these powders. The interactions between calcining temperature, sintering temperature, and pore former content were studied to identify the conditions necessary to produce PZT billets of the desired density and grain size. Several binder systems and pressing aids were evaluated for producing uniform sintered billets with low open porosity. The development of these processes supported the powder synthesis efforts and enabled comparisons between different chem-prep routes.

    While capillary electrophoresis-based technologies have been the mainstay for human identity typing applications, there are limitations with this methodology's resolution, scalability, and throughput. Massively parallel sequencing (MPS) offers the capability to multiplex multiple types of forensically-relevant markers and multiple samples together in one run all at an overall lower cost per nucleotide than traditional capillary electrophoresis-based methods; thus, addressing some of these limitations. MPS also is poised to expand forensic typing capabilities by providing new strategies for mixture deconvolution with the identification of intra-STR allele sequence variants and the potential to generate new types of investigative leads with an increase in the overall number and types of genetic markers being analyzed. The beta version of the Illumina ForenSeq DNA Signature Prep Kit is a MPS library preparation method with a streamlined workflow that allows for targeted amplification and sequencing of 63 STRs and 95 identity SNPs, with the option to include an additional 56 ancestry SNPs and 22 phenotypic SNPs depending on the primer mix chosen for amplification, on the MiSeq desktop sequencer (Illumina). This study was divided into a series of experiments that evaluated reliability, sensitivity of detection, mixture analysis, concordance, and the ability to analyze challenged samples.

    This study aimed to standardise an in-house real-time polymerase chain reaction (rtPCR) to allow quantification of hepatitis B virus (HBV) DNA in serum or plasma samples, and to compare this method with two commercial assays, the Cobas Amplicor HBV monitor and the Cobas AmpliPrep/Cobas TaqMan HBV test. Samples from 397 patients from the state of São Paulo were analysed by all three methods. Fifty-two samples were from patients who were human immunodeficiency virus and hepatitis C virus positive, but HBV negative. Genotypes were characterised, and the viral load was measure in each sample. The in-house rtPCR showed an excellent success rate compared with commercial tests; inter-assay and intra-assay coefficients correlated with commercial tests (r = 0.96 and r = 0.913, p < 0.001) and the in-house test showed no genotype-dependent differences in detection and quantification rates. The in-house assay tested in this study could be used for screening and quantifying HBV DNA in order to monitor patients during therapy. PMID:26872342

    Geosocial-networking smartphone applications are commonly used by gay, bisexual, and other men who have sex with men (MSM) to meet sexual partners. The purpose of the current study was to evaluate awareness of and willingness to use pre-exposure prophylaxis (PrEP) among MSM who use geosocial-networking smartphone applications residing in New York City. Recruitment utilizing broadcast advertisements on a popular smartphone application for MSM yielded a sample of 152 HIV-uninfected MSM. Multivariable models were used to assess demographic and behavioral correlates of awareness of and willingness to use PrEP. Most participants (85.5 %) had heard about PrEP but few (9.2 %) reported current use. Unwillingness to use PrEP was associated with concerns about side effects (PR = 0.303; 95 % CI 0.130, 0.708; p = 0.006). Given that more than half (57.6 %) of participants were willing to use PrEP, future research is needed to elucidate both individual and structural barriers to PrEP use among MSM.

    The current analysis evaluates interest in and acceptability of daily PrEP during short episodes of anticipated increased risk (i.e. Epi-PrEP). In 2013, U.S. members of an internet-based MSM sexual networking site were invited to complete a survey about HIV prevention practices in the context of vacationing. 7305 MSM responded to the survey. Of respondents who had vacationed in the past year, 25.6 % reported condomless anal sex (CAS) with new male sex partners while vacationing. Most (92.6 %) respondents agreed that having to use PrEP every day was a barrier to PrEP use and 74.3 % indicated they would take PrEP if they knew it would be helpful for short periods of anticipated increased risk. MSM who reported increased CAS while on vacation in the past year were more likely to indicate that they would take PrEP if it were helpful when used for short periods than respondents who did not (aOR = 2.02, 95 % CI 1.59-2.56, p < 0.001). Studies designed to evaluate uptake, adherence, and protective benefit of short PrEP courses are warranted. PMID:26538056

    Background: Pre-exposure prophylaxis (PrEP) with daily oral emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) prevents HIV infection. The safety and feasibility of HIV PrEP in the setting of hepatitis B virus (HBV) infection were evaluated. Methods: The Iniciativa Profilaxis Pre-Exposición study randomized 2499 HIV-negative men and transgender women who have sex with men to once-daily oral FTC/TDF versus placebo. Hepatitis serologies and transaminases were obtained at screening and at the time PrEP was discontinued. HBV DNA was assessed by polymerase chain reaction, and drug resistance was assessed by population sequencing. Vaccination was offered to individuals susceptible to HBV infection. Results: Of the 2499 participants, 12 (0.5%; including 6 randomized to FTC/TDF) had chronic HBV infection. After stopping FTC/TDF, 5 of the 6 participants in the active arm had liver function tests performed at follow-up. Liver function tests remained within normal limits at post-stop visits except for a grade 1 elevation in 1 participant at post-stop week 12 (alanine aminotransferase = 90, aspartate aminotransferase = 61). There was no evidence of hepatic flares. Polymerase chain reaction of stored samples showed that 2 participants in the active arm had evidence of acute HBV infection at enrollment. Both had evidence of grade 4 transaminase elevations with subsequent resolution. Overall, there was no evidence of TDF or FTC resistance among tested genotypes. Of 1633 eligible for vaccination, 1587 (97.2%) received at least 1 vaccine; 1383 (84.7%) completed the series. Conclusions: PrEP can be safely provided to individuals with HBV infection if there is no evidence of cirrhosis or substantial transaminase elevation. HBV vaccination rates at screening were low globally, despite recommendations for its use, yet uptake and efficacy were high when offered. PMID:26413853

    2016-01-01

    Geosocial-networking smartphone applications such as Grindr can help men who have sex with men (MSM) meet sexual partners. Given the high incidence of HIV in the Deep South, the purpose of our study was to assess HIV risk and preexposure prophylaxis (PrEP) awareness and use in a sample of HIV-uninfected, Grindr-using MSM residing in Atlanta, Georgia (n = 84). Most (n = 71; 84.6%) reported being somewhat or very concerned about becoming HIV infected. Most (n = 74; 88.1%) had been tested for HIV in their lifetimes. About three fourths (n = 65; 77.4%) were aware of PrEP, but only 11.9% currently used the medication. HIV continues to disproportionately impact MSM and represents a significant source of concern. As the number of new infections continues to rise, it is important to decrease risks associated with acquisition and transmission of HIV by increasing rates of HIV testing and the use of biobehavioral interventions such as PrEP.

    Full Text Available The plasma specimen is the gold standard for viral load monitoring, the key method to assess the effect of antiviral chemotherapy and to monitor progression of the disease toward AIDS. Nevertheless, several works endorse the use of dried blood spots (DBS on filter paper for the reliable quantification of the levels needed to take therapeutic decisions, detect of treatment failure and monitor the occurrence of drug resistance. The purpose of this study was to validate the use of Cobas AmpliPrep/Cobas TaqMan HIV-1 test version 2.0, with DBS. To evaluate the performance of the above mentioned kit, three stages were involved: 1- Standardization of DBS working conditions, 2- Stability studies at three temperature conditions and 3- Performance evaluation of the kit using this alternative specimen. Additionally, the viral load was quantified in parallel (plasma and DBS to 43 genetically characterized samples, with different levels of viral load. The Pearson correlation coefficient was calculated and the prediction of the value of RNA in plasma starting from the obtained value in DBS was made. Linear regression analysis was performed and coefficients of variation in precision assays were calculated. The best conditions pickups to the work with DBS were: 100 µL of blood (2 spots/50 µl, dried time between 16 and 18 hours at room temperature and, elution of the blood, 2 hours, between 2 and 8°C; in TRIS-EDTA buffer. The samples on DBS proved to be stable during the study periods. A strong correlation was attained between the measurements of viral load in plasma and DBS samples (r=0.96. The detection rate was 90.7 and the coefficient of variation between the values obtained in plasma-DBS sample pairs averaged 3.42%. The CAP/CTM HIV-1 test provided a linear response in DBS, from 330 copies/mL to 420 000 copies/mL. Overall, coefficients of variation in precision tests were below 10%. Cobas AmpliPrep/Cobas TaqMan HIV-1 test version 2.0 had a good

    Introduction Despite a number of HIV prevention strategies, the number of new HIV infections remains high. In Australia, over three-quarters of new HIV diagnoses are in gay and bisexual men (GBM). Pre-exposure prophylaxis (PrEP) has been shown to be effective at preventing new HIV infections in several randomised trials. The PRELUDE study aims to evaluate the implementation of PrEP in healthcare settings in New South Wales (NSW), Australia, among a sample of high-risk adults. Methods and analysis PRELUDE is an ongoing open-label, single-arm demonstration project, conducted in public and private clinics across NSW, Australia. Enrolment began in November 2014. The study is designed for 300 high-risk participants—mainly GBM and heterosexual women. Participants receive daily oral PrEP, composed of emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF), for up to 2.5 years. Quarterly study visits include testing for HIV and sexually transmitted infections (STIs), assessment of ongoing eligibility and side effects, and self-reported adherence. Following each study visit, online behavioural surveys are administered to collect information on medication adherence, risk behaviours and attitudes. Blood samples will be collected in a subset of patients 1, 6 and 12 months after PrEP initiation to measure FTC/TDF concentrations. Analyses using longitudinal regression models will focus on feasibility, adherence, safety, tolerability and effects of PrEP on behaviour. This study will inform PrEP policy and guide the implementation of PrEP in Australia in people at high risk of HIV. Ethics and dissemination The study will be conducted in accordance with the Declaration of Helsinki. All patients will provide written informed consent prior to participation in the study. Publications relating to each of the primary end points will be gradually released after 12 months of follow-up is complete. Trial registration number NCT02206555; Pre-results. PMID:27324719

    Specimens of poled 'chem-prep' PNZT ceramic from batch HF803 were tested under hydrostatic, uniaxial, and constant stress difference loading conditions at three temperatures of -55, 25, and 75 C and pressures up to 500 MPa. The objective of this experimental study was to obtain the electro-mechanical properties of the ceramic and the criteria of FE (Ferroelectric) to AFE (Antiferroelectric) phase transformations so that grain-scale modeling efforts can develop and test models and codes using realistic parameters. The poled ceramic undergoes anisotropic deformation during the transition from a FE to an AFE structure. The lateral strain measured parallel to the poling direction was typically 35 % greater than the strain measured perpendicular to the poling direction. The rates of increase in the phase transformation pressures per temperature changes were practically identical for both unpoled and poled PNZT HF803 specimens. We observed that the retarding effect of temperature on the kinetics of phase transformation appears to be analogous to the effect of shear stress. We also observed that the FE-to-AFE phase transformation occurs in poled ceramic when the normal compressive stress, acting perpendicular to a crystallographic plane about the polar axis, equals the hydrostatic pressure at which the transformation otherwise takes place.

  19. Chem-Prep PZT 95/5 for Neutron Generator Applications: Powder Fractionation Study of Production-Scale Powders

    International Nuclear Information System (INIS)

    The Materials Chemistry Department 1846 has developed a lab-scale chem-prep process for the synthesis of PNZT 95/5, referred to as the ''SP'' process (Sandia Process). This process (TSP) has been successfully transferred to and scaled-up by Department 14192 (Ceramics and Glass Department), producing the larger quantities of PZT powder required to meet the future supply needs of Sandia for neutron generator production. The particle size distributions of TSP powders routinely have been found to contain a large particle size fraction that was absent in development (SP) powders. This SAND report documents experimental studies focused on characterizing these particles and assessing their potential impact on material performance. To characterize these larger particles, fractionation of several TSP powders was performed. The ''large particle size fractions'' obtained were characterized by particle size analysis, SEM, and ICP analysis and incorporated into compacts and sintered. Large particles were found to be very similar in structure and composition as the bulk of the powder. Studies showed that the large-size fractions of the powders behave similarly to the non-fractionated powder with respect to the types of microstructural features once sintered. Powders were also compared that were prepared using different post-synthesis processing (i.e. differences in precipitate drying). Results showed that these powders contained different amounts and sizes of porous inclusions when sintered. How this affects the functional performance of the PZT 95/5 material is the subject of future investigations

    Liquid-based cytology (LBC) has replaced conventional smear assessment in many centers over recent years. In our laboratory this transfer took place in 1999. At that time we performed a split sample study comparing the conventional method of cervical smear evaluation with the ThinPrep system. This split sample study identified a dramatic improvement in specimen adequacy with LBC. While 11% of conventional preparations were reported as unsatisfactory and almost 9% were reported as suboptimal, evaluation of the same cases using LBC saw this combined figure reduced to 2.3%. AIM: To evaluate whether this dramatic fall in unsatisfactory smears has been maintained with the use of LBC. The database for all smears reported for 2005 (100% LBC) was interrogated. The number of unsatisfactory reports was calculated. The reason for an unsatisfactory report was recorded for each case. The overall unsatisfactory rate was compared with that reported in the 1999 split sample study. A total of 41,312 smear tests were reported in 2005. 1,342 (3.25%) were reported as unsatisfactory. Our findings support the ongoing value of LBC in a routine cervical screening laboratory in terms of continuing to maintain a low rate of unsatisfactory smears.

  1. Strong relationship between oral dose and tenofovir hair levels in a randomized trial: hair as a potential adherence measure for pre-exposure prophylaxis (PrEP.

    Full Text Available Pre-exposure prophylaxis (PrEP trials using tenofovir-based regimens have demonstrated that high levels of adherence are required to evaluate efficacy; the incorporation of objective biomarkers of adherence in trial design has been essential to interpretation, given the inaccuracy of self-report. Antiretroviral measurements in scalp hair have been useful as a marker of long-term exposure in the HIV treatment setting, and hair samples are relatively easy and inexpensive to collect, transport, and store for analysis. To evaluate the relationship between dose and tenofovir concentrations in hair, we examined the dose proportionality of tenofovir in hair in healthy, HIV-uninfected adults.A phase I, crossover pharmacokinetic study was performed in 24 HIV-negative adults receiving directly-observed oral tenofovir tablets administered 2, 4, and 7 doses/week for 6 weeks, with a ≥3-week break between periods. Small samples of hair were collected after each six-week period and analyzed for tenofovir concentrations. Geometric-mean-ratios compared levels between each pair of dosing conditions. Intensive plasma pharmacokinetic studies were performed during the daily-dosing period to calculate areas-under-the-time-concentration curves (AUCs.Over 90% of doses were observed per protocol. Median tenofovir concentrations in hair increased monotonically with dose. A log-linear relationship was seen between dose and hair levels, with an estimated 76% (95% CI 60-93% increase in hair level per 2-fold dose increase. Tenofovir plasma AUCs modestly predicted drug concentrations in hair.This study found a strong linear relationship between frequency of dosing and tenofovir levels in scalp hair. The analysis of quantitative drug levels in hair has the potential to improve adherence measurement in the PrEP field and may be helpful in determining exposure thresholds for protection and explaining failures in PrEP trials. Hair measures for adherence monitoring may also

    We conducted a longitudinal and cross-sectional analysis of depressive symptomology in iPrEx, a randomized, placebo-controlled trial of daily, oral FTC/TDF HIV pre-exposure prophylaxis (PrEP) in men and transgender women who have sex with men. Depression-related adverse events (AEs) were the most frequently reported severe or life-threatening AEs and were not associated with being randomized to the FTC/TDF arm (152 vs. 144 respectively OR 0.66 95 % CI 0.35-1.25). Center for Epidemiologic Studies Depression scale (CES-D) and a four questions suicidal ideation scale scores did not differ by arm. Participants reporting forced sex at anal sexual debut had higher CES-D scores (coeff: 3.23; 95 % CI 1.24-5.23) and were more likely to have suicidal ideation (OR 2.2; 95 % CI 1.09-4.26). CES-D scores were higher among people reporting non-condom receptive anal intercourse (ncRAI) (OR 1.46; 95 % CI 1.09-1.94). We recommend continuing PrEP during periods of depression in conjunction with provision of mental health services. PMID:26078115

    2014-11-01

    Full Text Available Introduction: Truvada is licenced for HIV-1 prevention in the USA and is available in the private sector. Tenofovir performed as well as Truvada in the PARTNERS PrEP study and is used as HIV pre-exposure prophylaxis (PreP in some settings. The clinical efficacy of Tenofovir for PrEP outside a clinical trial is unknown. Antiretroviral therapy (ART at acute HIV-1 infection (AHI limits the size of the reservoir, optimizing the chance of maintaining viral control off therapy. As such ART at acute HIV infection is proposed to offer a functional cure in a minority of subjects. We present two cases where Tenofovir PrEP failed to prevent HIV acquisition and failed to limit viral reservoir. Materials and Methods: Two individuals receiving tenofovir monotherapy for Hepatitis B monoinfection were diagnosed with AHI as defined by a negative HIV antibody test within three months of a positive HIV test following unsafe sex with casual male partners. In-depth histories were taken. Viral genotypes and Tenofovir drug levels were measured from samples taken as close to HIV seroconversion as possible and subsequent samples were analyzed for proviral Total HIV-1 DNA by qPCR. Results: Patient A had received tenofovir for the preceding six years and always maintained an undetectable Hepatitis B viral load with no concerns about adherence. Two weeks preceding the positive HIV antibody test, he experienced mild symptoms (fever, pharyngitis of HIV seroconversion. HIV status was confirmed by a repeat fourth generation HIV antibody test and by Western Blot and an HIV viral load was undetectable. Tenofovir trough level at HIV diagnosis was within normal limits. The regimen was intensified to Eviplera and a total HIV-1 DNA was 1381 copies/million CD4 T cells. Patient B received four regimens for hepatitis B treatment before starting tenofovir monotherapy in 2011 and subsequently maintained an undetectable hepatitis B viral load. After three years of tenofovir monotherapy he

  5. Chemoprophylaxis in the vesical tumoral recurrence

    International Nuclear Information System (INIS)

    The superficial bladder tumors are characterized by a high rate of recurrence taking place especially within the first two years that is even higher in the high risk groups. There is an agreement in the usefulness of the Calmette-Guerin Bacillus (CGB) to diminish the tumoral recurrence. The intravesical chemotherapy with other medications have demonstrated its profit or not in decreasing the recurrence of these bladder tumors. Between 1999 and 2008 we studied and treated 110 patients (96 men and 14 women), aged in average 63 years old. They were divided into three groups for the treatment of the tumoral recidivism after the transurethral resection or partial cystectomy, using three different chemoprophylactic agents and inmunomodulators (Thio-Tepa, BCG+Transference Factor, Doxorubicin +Interferon Alpha 2b). The objective of this research was presenting our experience in the treatment of these patients during five years, obtaining better results in the group treated with doxorubicin + interferon alpha 2b, followed by the group treated by means of BCG + transference factor, with a remarked decrease of the recurrence and a limitation in the long term progression of the disease

    Traveler's diarrhea is a very common condition that affects approximately 12 million subjects each year. This disorder is benign but nevertheless interferes with the traveler's plans in 40% of cases. Several drugs have been used for prophylaxis, in association with appropriate precautions concerning food and drink. Trimethoprim-sulfamethoxazole and cyclines are effective but may induce adverse effects. Nifuroxazide in a dose of 400 mg each day throughout the trip has proved effective. Tolerance was outstanding with no adverse effects. PMID:3534765

    The overall goal of the project partially funded by DOE was to encourage a greater number of the targeted high school students to acquire the necessary skills to succeed in rigorous college academic programs and to enter science-based disciplines. These goals were met and the program was judged to be a success. Students participating in the program were involved in a rigorous daily academic program of formal instruction. Participants lived in the residence halls and participated in many aspects of college life, including planned recreational activities. Students were also involved in academic year activities to maintain a heightened awareness and interest in science-based fields. The program sought to provide students with the following hands on laboratory and field site learning experiences as well as minority role models--scientists and engineers, resident advisors, and tutors. Curricular focal points were environmental science, supported by courses and labs in mathematics, technical writing, and chemistry. The 1994 summer program was the second year of the environmental science focus. Students chose topics relevant to New Mexico such as Coal Mining, Landfills, and Tribal Water Rights. The program was judged to have succeeded in the overall goal of encouraging targeted precollege students to acquire the necessary skills to succeed in rigorous college academic programs and to enter science-based disciplines.

    2011-05-01

    Full Text Available The preprocessor PREP-CHEM-SRC presented in the paper is a comprehensive tool aiming at preparing emission fields of trace gases and aerosols for use in atmospheric-chemistry transport models. The considered emissions are from the most recent databases of urban/industrial, biogenic, biomass burning, volcanic, biofuel use and burning from agricultural waste sources. For biomass burning, emissions can be also estimated directly from satellite fire detections using a fire emission model included in the tool. The preprocessor provides emission fields interpolated onto the transport model grid. Several map projections can be chosen. The inclusion of these emissions in transport models is also presented. The preprocessor is coded using Fortran90 and C and is driven by a namelist allowing the user to choose the type of emissions and the databases.

    Following the demise of apartheid, human rights in South Africa are now constitutionally enshrined.The right to health in South Africa's Constitution has been credited with transforming the lives of millions of people by triggering programmatic reforms in HIV treatment and the prevention of mother to child transmission (MTCT) of HIV.However, a constitutionally enshrined right to health offers no guarantee that clinical trial participants will enjoy post-trial access to beneficial interventions. Using access to HIV pre-exposure prophylaxis (PrEP) in South Africa as an example, this paper argues that adherence to bioethics norms could realize the right to health for trial participants following the end of a clinical trial.

    2003-10-01

    Sandia is currently developing a lead-zirconate-titanate ceramic 95/5-2Nb (or PNZT) from chemically prepared ('chem-prep') precursor powders. Previous PNZT ceramic was fabricated from the powders prepared using a 'mixed-oxide' process. The specimens of unpoled PNZT ceramic from batch HF803 were tested under hydrostatic, uniaxial, and constant stress difference loading conditions within the temperature range of -55 to 75 C and pressures to 500 MPa. The objective of this experimental study was to obtain mechanical properties and phase relationships so that the grain-scale modeling effort can develop and test its models and codes using realistic parameters. The stress-strain behavior of 'chem-prep' PNZT under different loading paths was found to be similar to that of 'mixed-oxide' PNZT. The phase transformation from ferroelectric to antiferroelectric occurs in unpoled ceramic with abrupt increase in volumetric strain of about 0.7 % when the maximum compressive stress, regardless of loading paths, equals the hydrostatic pressure at which the transformation otherwise takes place. The stress-volumetric strain relationship of the ceramic undergoing a phase transformation was analyzed quantitatively using a linear regression analysis. The pressure (P{sub T1}{sup H}) required for the onset of phase transformation with respect to temperature is represented by the best-fit line, P{sub T1}{sup H} (MPa) = 227 + 0.76 T (C). We also confirmed that increasing shear stress lowers the mean stress and the volumetric strain required to trigger phase transformation. At the lower bound (-55 C) of the tested temperature range, the phase transformation is permanent and irreversible. However, at the upper bound (75 C), the phase transformation is completely reversible as the stress causing phase transformation is removed.

    The industry of next-generation sequencing is constantly evolving, with novel library preparation methods and new sequencing machines being released by the major sequencing technology companies annually. The Illumina TruSeq v2 library preparation method was the most widely used kit and the market leader; however, it has now been discontinued, and in 2013 was replaced by the TruSeq Nano and TruSeq PCR-free methods, leaving a gap in knowledge regarding which is the most appropriate library preparation method to use. Here, we used isolates from the pathogenic fungi Cryptococcus neoformans var. grubii and sequenced them using the existing TruSeq DNA v2 kit (Illumina), along with two new kits: the TruSeq Nano DNA kit (Illumina) and the NEBNext Ultra DNA kit (New England Biolabs) to provide a comparison. Compared to the original TruSeq DNA v2 kit, both newer kits gave equivalent or better sequencing data, with increased coverage. When comparing the two newer kits, we found little difference in cost and workflow, with the NEBNext Ultra both slightly cheaper and faster than the TruSeq Nano. However, the quality of data generated using the TruSeq Nano DNA kit was superior due to higher coverage at regions of low GC content, and more SNPs identified. Researchers should therefore evaluate their resources and the type of application (and hence data quality) being considered when ultimately deciding on which library prep method to use.

    The MonoPrep Pap Test (MPPT; MonoGen, Lincolnshire, IL) is a novel, liquid-based specimen collection and processing technology for cytologic and molecular testing. Its usefulness in the detection of cervical cancer and its precursors was evaluated in a multicenter, masked, adjudicated, split-sample study of 10,739 samples. After preparation of a conventional smear, the residuum on the collection device was rinsed into a collection vial from which an MPPT slide was prepared. Accuracy was assessed by masked reference interpretation by an independent pathologist. Slides prepared by MPPT, compared with smears, yielded statistically significant increases in relative sensitivity for atypical squamous cells of undetermined significance and worse, atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion/atypical glandular cells and worse, and low-grade squamous intraepithelial lesion and worse. There was no significant difference in relative specificity. MPPT provided a 58% reduction in unsatisfactory slides. There was no significant difference in the presentation of endocervical/transformation zone component or the detection of benign conditions. The MPPT is a promising new liquid-based technology for cervical cancer screening. PMID:18208798

    Prospective studies analyzing the ThinPrep Imaging System (TIS) have demonstrated a significant decrease in screening time and detection rates comparable or better than manual screening. We retrospectively analyzed the accuracy of the TIS in detecting cervical abnormalities. Our study included all new HSIL diagnoses in 2007 with previous negative (NIL) pap tests screened with TIS. The original 22 fields of view (FOV) were reviewed by 2 blinded screeners followed by manual screening of all slides. Any ASC-US or above was considered "abnormal." Of a total of 111,080 pap tests performed in 2007, 180 were reported as HSIL. Of these, 45 cases had a previous NIL pap diagnosed within the last year, screened with TIS. Following re-examination of the NIL pap, 31 diagnoses remained unchanged and 9 were reclassified as abnormal on the basis of cells present within the original FOV. When manually reviewed, all nine cases were confirmed as abnormal. Four cases were reclassified as abnormal on the basis of the manual screen (abnormal cells absent in the FOV). The sensitivity of TIS for the detection of abnormality was 99.95% (false-negative rate FNR: 0.05%) and the sensitivity for detection of HSIL was 99.07% (FNR: 0.92%). When analyzing the cytotechnologist interpretation of the FOV, the sensitivity for detection of abnormality and HSIL was 99.89% (FNR: 0.1%), and 99.53% (FNR: 0.4%), respectively. On retrospective analysis based on newly diagnosed HSIL cases, the sensitivity of TIS was comparable to that of manual screening with a slightly decreased rate of false negatives.

    Background Conventional transbronchial needle aspiration (c-TBNA) contributed to improve the bronchoscopic examination, allowing to sample lesions located even outside the tracheo-bronchial tree and in the hilo-mediastinal district, both for diagnostic and staging purposes. Methods We have evaluated the sensitivity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the c-TBNA performed during the 2005–2015 period for suspicious lung neoplasia and/or hilar and mediastinal lymphadenopathy at the Thoracic endoscopy of the Thoracic Surgery Department of the Regina Elena National Cancer Institute, Rome. Data from 273 consecutive patients (205 males and 68 females) were analyzed. Results Among 158 (58%) adequate specimens, 112 (41%) were neoplastic or contained atypical cells, 46 (17%) were negative or not diagnostic. We considered in the analysis first the overall period; then we compared the findings of the first [2005–2011] and second period [2012–2015] and, finally, only those of adequate specimens. During the overall period, sensibility and accuracy values were respectively of 53% and 63%, in the first period they reached 41% and 53% respectively; in the second period sensibility and accuracy reached 60% and 68%. Considering only the adequate specimens, sensibility and accuracy during the overall period were respectively of 80% and 82%; the values obtained for the first period were 68% and 72%. Finally, in the second period, sensibility reached 86% and accuracy 89%. Carcinoma-subtyping was possible in 112 cases, adenocarcinomas being diagnosed in 50 cases; further, in 30 cases molecular predictive data could be obtained. Conclusions The c-TBNA proved to be an efficient method for the diagnosis/staging of lung neoplasms and for the diagnosis of mediastinal lymphadenopathy. Endoscopist’s skill and technical development, associated to thin-prep cytology and to a rapid on site examination (ROSE), were able to provide by c-TBNA a

    Full Text Available Another major force not letting us succeed in the treatment of diabetes remains right inside the patients home, their family members. Hence, it is important to know the perception of the close family members about this simple and strong tool in diabetes, ′insulin′. The drug is nearing its century, it has not fully being accepted gracefully even in todays electronic savvy society. So, we need to strongly discover the reason for its non-acceptance, while trials are out inventing new drugs. One vital thing that can change this attitude is increasing the understanding of this drug, insulin in depth to close people around the patient, the ′family′. Underestimating family′s perception about disease and treatment for diabetes is detrimental to both diseased and the doctor. This consists of a biopsychosocial model; biological, psychological and social factors. Family forms the most important part of it. The strategies in family therapy include psychodynamic, structural, strategic, and cognitive-behavioral component. Diabetes has and will continue to rise, so will be the treatment options. From the clinicians side its to fix fasting first but from patients its fix family first. Family therapy demonstrates the importance of insulin initiation and maintenance in insulin naive patients, and continuation for others. The specific needs of such patients and their impact on family life are met with family therapy. Who needs family therapy? Benefits of family therapy and a case based approach is covered.

    Full Text Available Background: ThinPrep® (TP cervical cytology, as a liquid-based method, has many benefits but also a relatively high unsatisfactory rate due to debris/lubricant contamination and the presence of blood. These contaminants clog the TP filter and prevent the deposition of adequate diagnostic cells on the slide. An acetic acid wash (AAW protocol is often used to lyse red blood cells, before preparing the TP slides. Design: From 23,291 TP cervical cytology specimens over a 4-month period, 2739 underwent AAW protocol due to initial unsatisfactory smear (UNS with scant cellularity due to blood or being grossly bloody. Randomly selected 2739 cervical cytology specimens which did not undergo AAW from the same time period formed the control (non-AAW group. Cytopathologic interpretations of AAW and non-AAW groups were compared using the Chi-square test. Results: About 94.2% of the 2739 cases which underwent AAW were subsequently satisfactory for evaluation with interpretations of atypical squamous cells of undetermined significance (ASCUS 4.9% (135, low-grade squamous intraepithelial lesions (LSIL 3.7% (102, and high-grade squamous intraepithelial lesions (HSIL 1% (28.

    Langs, R

    In this paper an attempt is made to conceptualize a basic dimension of various psychotherapeutic treatment modalities, especially psychoanalysis and psychoanalytically oriented psychotherapy. The central variable under consideration is the extent to which each endeavors to approach the truth within both patient and therapist as it exists dynamically in terms of their spiraling unconscious communicative interaction. That treatment modality which takes into account every possible dimension of such truths is termed truth therapy. Treatment modalities that make no attempt to arrive at these truths or that deliberately or inadvertently falsify their nature are termed lie or barrier therapies. Extensive consideration is given to truth therapy and the truth system on which it is based. The basis for the need for lie therapies is explored, and lie systems, which may arise from either patient or therapist, or both, are identified. A classification of common types of lie patients and lie therapists (and their main techniques) is offered. The implications of this delineation for our understanding of the dynamic therapies are discussed, and a number of new clinical issues arising from this perspective are addressed.

    Traditionally, many advances in medicine have been serendipitous. Are serendipitous and anecdotal synonymous? Many of our materia medica today relate to initial probes and anecdotal reports that matured to full investigation and therapeutic indications. The recent situation regarding Skin Cap is one that highlights the downside of this scenario. Several drugs in the US continue usage largely related to anecdotal indications, and anecdotal extension of legend indications is a standard for American Dermatology. The situation with systemic drugs, such as Trental, zinc preparations, imidazoles for extended indications, lysine and melatonin, all will be discussed. Topical preparations such as skin cap, cantharone, Vioform, all also are included in this category. It is important to place this topic in perspective in regards to geographic variation and therapeutic need. Many diseases lacking specific therapy are important targets for anecdotal therapy, and this will foster continued approaches in this area. The growing standardization of medicine and pharmaceutical regulation, threatens the anecdotal approach, but it provides still an important link to the future for some forms of therapy in diseases that are difficult to treat. Traditionally, the anecdote has been the first step in the therapeutic chain. Withering discovery of the benefits of the common fox glove in dropsy, was followed by many other anecdotes arriving via folk-medicine in the New World. This approach of utilizing folk medicine has now reached new heights, with very active searches by major pharmaceutical companies throughout the third world for remedies that may have potential. Couched with this is the history of anecdotal "snake-oil" remedies, that clearly had no benefit to anyone except the huckster marketing same. The excesses in this area of unproven and false therapies, led to the gradual organization of therapeutic trials and the Food and Drug Administration in the US as we know it today. The

    Full text: Historically discoveries and technological advances in radiation and accelerator physics have been rapidly applied in the healing arts. X rays, discovered by Roentgen in 1895, and radioisotopes, discovered by Becquerel in 1896, were both applied to the treatment of cancer by the first year of the twentieth century. By the time that Chadwick discovered the neutron in 1932 radiotherapy was a well-established modality for the treatment of cancer. The potential use of neutrons in radiotherapy was immediately recognized by L.H. Gray (a recent Ph.D. graduate from the Cavendish laboratories in Cambridge). He built a neutron generator for radiobiology research at Mount Vernon Hospital in London, it's design was based on a similar device built at Cambridge by Mark Oliphant. In parallel with these developments Earnest Lawrence, in collaboration with his brother John Lawrence, a physician, were also studying the radiobiology of neutrons. They obtained some funding from the US National Cancer Institute to construct a 60'' cyclotron for neutron radiation therapy. These clinical trials, started in 1938, were the first application of heavy particles for cancer therapy. Immediately after the second World War advances in accelerator technology lead to the building of the first synchrocyclotrons, which produced proton beams with ranges approaching 30 cm in water. At the Harvard synchrocyclotron Robert R. Wilson realized that proton beams might have considerable advantages over other radiation beams in the treatment of deep-seated tumors. This advantage derives from the increase in stopping power at the end of the proton range, first observed by W.H.Bragg at the University of Adelaide; a phenomenon now known as the Bragg peak. Conventional X-ray beams are exponentially attenuated by matter and, hence, delivering large radiation doses to tumors at depth while not causing excessive damage to the overlying normal tissues can be problematical. The Bragg peak and the well

    Particle therapy has a long history. The experimentation with particles for their therapeutic application got started soon after they were produced in the laboratory. Physicists played a major role in proposing the potential applications in radiotherapy as well as in the development of particle therapy. A brief review of the current status of particle radiotherapy with some historical perspective is presented and specific contributions made by physicists will be pointed out wherever appropriate. The rationale of using particles in cancer treatment is to reduce the treatment volume to the target volume by using precise dose distributions in three dimensions by using particles such as protons and to improve the differential effects on tumors compared to normal tissues by using high-LET radiations such as neutrons. Pions and heavy ions combine the above two characteristics.

    Proton therapy is one of the most rapidly developing new treatment technologies in radiation oncology. This treatment approach has — after roughly 40 years of technical developments — reached a mature state that allows a widespread clinical application. We therefore review the basic physical and radio-biological properties of proton beams. The main physical aspect is the elemental dose distribution arising from an infinitely narrow proton pencil beam. This includes the physics of proton stopping powers and the concept of CSDA range. Furthermore, the process of multiple Coulomb scattering is discussed for the lateral dose distribution. Next, the basic terms for the description of radio-biological properties of proton beams like LET and RBE are briefly introduced. Finally, the main concepts of modern proton dose delivery concepts are introduced before the standard method of inverse treatment planning for hadron therapy is presented.

    Radiotherapy is one of the most important means we have for the treatment of localised tumours. It is therefore essential to optimize the technique, and a lot of effort goes into this endeavour. Since the proposal by Wilson in 1946 [R.R. Wilson, Radiology use of fast protons, Radiology 47 (1946) 487.] that proton beams might be better than photon beams at inactivating cancer cells, hadron therapy has been developed in parallel with photon therapy and a substantial knowledge has been gained on the effects of pions, protons and heavy ions (mostly carbon ions). Here we discuss the recent measurements by the CERN ACE collaboration of the biological effects of antiprotons, and argue that these particles very likely are the optimal agents for radiotherapy.

    Full Text Available Introduction: Automated screening of Thin Prep ® Papanicolaou Tests has become increasingly common in clinical practice. Increased productivity has initiated laboratory use of the Thin Prep ® Imaging System (TIS. Increased sensitivity is a potential additional benefit of TIS. Published studies have shown an increase in discovery of dysplastic cells. This study evaluates the effect of TIS on the incidence of atypical squamous cells high-grade squamous intraepithelial lesion not excluded (ASC-H and high-grade squamous intraepithelial lesion (HGSIL results on Thin Prep ® Pap Tests by comparing TIS-assisted and manual screening findings and the diagnoses on subsequent follow-up in a screening population over a 1-year time period. Materials and Methods: A compilation of all ASC-H and HGSIL cases was prepared by conducting a computerized search over a 1-year period (7/06-6/07. The accumulated cases include Thin Prep Pap tests that were both TIS and manually screened. Follow-up results of cytologic and histologic cervical specimens were obtained for a time period extending to 2010. Interpretation utilizing TIS was in place 10 months prior to the study′s initiation. Results: During the study period 70,522 Pap tests were performed in our laboratory. One third (33% of Pap tests were screened with assistance of TIS. Manual screening was performed on 47,380 Pap tests of which 153 (0.32% were interpreted as ASC-H and 164 (0.35% were interpreted as HGSIL. During the same time period automated screening (TIS was performed on 23,111 Pap tests. Interpretation of 62 (0.27% cases provided an ASC-H result, while 71 (0.31% were HGSIL. Follow-up cervical dysplasia by colposcopic biopsy and cone biopsy was distributed proportionally between TIS and manual screening for both ASC-H and HGSIL categories. Cervical intraepithelial neoplasia (CIN II/III was identified on follow-up biopsy of 41% TIS cases and 45% manually screened cases for ASC-H. In the HGSIL subset 71

    2015-01-01

    Full Text Available El estado morfofuncional del sistema reproductivo de las ovejas es determinado por las hormonas sexuales, que actúan por medio de receptores específicos, desencadenando una serie de cambios celulares, metabólicos y proliferativos dependientes de la expresión de numerosos genes. A diferencia de otros mamíferos, las ovejas presentan en el endometrio y posiblemente otros órganos del sistema reproductivo receptores de estrógenos fisiológicamente activos desde la etapa prepuberal cuya función aún no está esclarecida. La información sobre la expresión de receptores de hormonas sexuales en el aparato reproductor es muy escasa, sobre todo en el ovario y no existen estudios que correlacionen la raza con la expresión de estos receptores. Generalmente los criadores privilegian razas de mayor nivel de prolificidad y esto podría estar relacionado con el nivel de expresión de los receptores de estrógeno en el sistema reproductivo. El objetivo del presente trabajo fue evaluar comparativamente la expresión transcripcional del receptor de estrógeno en el ovario de ovejas prepúberes de raza Texel de alta prolificidad y de raza Criolla Araucana de prolificidad estándar, mediante análisis de RT-PCR en tiempo real cuantitativo.

  14. Screening for Latent Tuberculosis in the Patient With Moderate to Severe Psoriasis Who Is a Candidate for Systemic and/or Biologic Therapy.

    Science.gov (United States)

    Martínez-López, A; Rodriguez-Granger, J; Ruiz-Villaverde, R

    2016-04-01

    Screening to detect latent tuberculosis infection (LTBI) is essential before patients with moderate to severe psoriasis start treatment with biologics and vigilance will continue to be needed during and after such treatment. The most recently analyzed statistics from the BIOBADADERM registry show a 20.5% prevalence of LTBI in psoriasis patients treated with biologics in Spain. Various screening protocols are in effect in different countries according to their levels of endemic TB and bacillus Calmette-Guérin (BCG) vaccination, and there is no consensus on a gold-standard approach to the diagnosis of LTBI. Tuberculin skin testing (TST) continues to be the diagnostic method of choice in spite of its limited sensitivity, mainly in immunocompromised patients. Additional problems include the TST's well-established lack of specificity, errors in application, subjectivity in the interpretation of results (which must be read during a second visit), and lack of privacy; the main advantages of this test are its low cost and ease of application. Most cost-benefit studies are therefore inclined to favor using interferon-γ release assays to detect LTBI because they minimize false positives (especially in BCG-vaccinated individuals), thereby eliminating the extra costs and side effects of unnecessary chemoprophylaxis. We review the methods used for LTBI screening in psoriasis patients who are candidates for biologic therapy. Additionally, given the fact that most guidelines do not currently consider it necessary to screen patients about to start conventional systemic therapy, we discuss the reasons underlying the need for such screening.

    Full Text Available Art therapy is a form of expressive therapy that uses art materials. Art therapy combines traditional psychotherapeutic theories and techniques with an understanding of the psychological aspects of the creative process, especially the affective properties of the different art materials. Medical art therapy has been defined as the clinical application of art expression and imagery with individuals who are physically ill, experiencing physical trauma or undergoing invasive or aggressive medical procedures such as surgery or chemotherapy and is considered as a form of complementary or integrative medicine. Several studies have shown that patients with physical illness benefit from medical art therapy in different aspects. Unlike other therapies, art therapy can take the patients away from their illness for a while by means of creative activities during sessions, can make them forget the illness or lost abilities. Art therapy leads to re-experiencing normality and personal power even with short creative activity sessions. In this article definition, influence and necessity of medical art therapy are briefly reviewed.

    Full Text Available The present essay is a short and probably superficial analysis of music therapy and music therapy research. I have to say that by no means do I consider myself an expert or even experienced enough to provide "critiques" about any area of music therapy. This work is a revised version of a term paper presented at the University of Kansas in 2002, and is just the result of my interest in some recent trends of thoughts (e.g. social constructionism, and their impact, if any, on music therapy. I believe in dialogue as a means to forward knowledge, and so I dare to share this work with colleagues.

    Full Text Available Genes are specific sequences of bases that encode instructions to make proteins. When genes are altered so that encoded proteins are unable to carry out their normal functions, genetic disorders can result. Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. This article reviews the fundamentals in gene therapy and its various modes of administration with an insight into the role of gene therapy in Periodontics and future percepts and the technical and ethical issues of using gene therapy.

    Full Text Available The therapeutic community described in this paper was situated at the University of Oulu Central Hospital Department of Psychiatry, Finland, during the years 1979-1989. The ward consisted of eight beds, four for boys and four for girls. The basic emphasis in the treatment was laid on psychoanalytic psychotherapy and music and art therapies suitable for the stage of adolescent development. Adolescent community therapy (psychoanalytic psychotherapy, music therapy, art therapy, special school etc. creates an environment which supports individual growth of the adolescent and youth culture. This, in turn, simultaneously supports psychotherapy.

    At Sansei Hospital in Kyoto we performed Morita Therapy not only for Japanese clients but also foreign clients from several countries, like Germany, Switzerland, U.S.A., China, Korea, India and Indonesia. We could treat those foreign clients using Morita Therapy with good success although they came from various cultural backgrounds. One of the characteristic Approaches of Morita Therapy was that it avoided the conceptualization of self-consciousness and self image as a subjective fiction established by abstract and logical thinking. Secondary Morita Therapy moves clients to deal with activities in real life. These 2 approaches help clients not to be involved in symptom development or fixation mechanisms and break through self-centeredness. At the first stage of Morita Therapy, namely in the bed rest period clients can experience his psychic state as if he were a just born baby. The founder of Gestalt Therapy, Frederick S. Perls experienced by himself Morita Therapy. During bed rest therapy he behaved as if he were a baby. This behavior came out not from conscious abstract and logical thinking but from spontaneous "pre-conscious" state of mind. Morita called this "Jun-na-kokoro" (Pure mind). Morita knew that neurotic symptoms come out from those abstract and logical thinking which could lead to fixation of symptoms so that therapy principle might be the de-centralization of self and the pure mind experience which is found in our daily life and also in daily life of foreign people from various cultural backgrounds.

    Radioiodine therapy of benign and malignant thyroid diseases is a well-established procedure in Nuclear Medicine. However, the therapeutic use of radioisotopes in other diseases is relatively unknown among our refering physicians. The therapeutic effects of intraarticular (rheumatoid arthritis) and intracavitary (pleural and peritoneal carcinosis) applications yields good results. The radiophosphorus therapy in polycythemia vera rubra has always to be considered as an alternative to chemotherapy. The use of analgetics may be reduced by pain therapy of bone metastasis by injection of bone-seeking beta emitters like Rh-186 HEDP. Other procedures like therapeutic application of meta-iodo-benzylguanidine in neuroblastoma and malignant pheochromocytoma resulted in at least remissions of the disease. Radioimmunotherapy needs further evaluation before it can be recommended as a routine procedure. (orig.).

    Although cognitive behavioral therapy (CBT) is widely recognized as the preferred treatment of psychiatric disorders, less is known about the application of CBT to substance use disorders, particularly in adolescence. This article discusses how CBT conceptualizes substance use and how it is implemented as a treatment of adolescent substance abuse. The article draws on several manuals for CBT that implement it as a standalone treatment or in combination with motivational enhancement therapies. Also reviewed are several studies that examined the efficacy of CBT. Finally, the implications are discussed. Numerous starting resources are provided to help a clinician implement CBT.

  9. Music therapy improvisation

    Directory of Open Access Journals (Sweden)

    Mira Kuzma

    2001-09-01

    Full Text Available In this article, the technique of music therapy – music therapy improvisation is introduced. In this form of music therapy the improvising partners share meaning through the improvisation: the improvisation is not an end in itself: it portrays meaning that is personal, complex and can be shared with the partner. The therapeutic work, then, is meeting and matching the client's music in order to give the client an experience of "being known", being responded through sounds and being able to express things and communicate meaningfully. Rather than the client playing music, the therapy is about developing the engagement through sustained, joint improvisations. In music therapy, music and emotion share fundamental features: one may represent the other, i.e., we hear the music not as music but as dynamic emotional states. The concept of dynamic structure explains why music makes therapeutic sense.

  10. Medical therapy in acromegaly.

    LENUS (Irish Health Repository)

    Sherlock, Mark

    2011-05-01

    Acromegaly is a rare disease characterized by excess secretion of growth hormone (GH) and increased circulating insulin-like growth factor 1 (IGF-1) concentrations. The disease is associated with increased morbidity and premature mortality, but these effects can be reduced if GH levels are decreased to <2.5 μg\\/l and IGF-1 levels are normalized. Therapy for acromegaly is targeted at decreasing GH and IGF-1 levels, ameliorating patients\\' symptoms and decreasing any local compressive effects of the pituitary adenoma. The therapeutic options for acromegaly include surgery, radiotherapy and medical therapies, such as dopamine agonists, somatostatin receptor ligands and the GH receptor antagonist pegvisomant. Medical therapy is currently most widely used as secondary treatment for persistent or recurrent acromegaly following noncurative surgery, although it is increasingly used as primary therapy. This Review provides an overview of current and future pharmacological therapies for patients with acromegaly.

  11. Proton therapy physics

    2012-01-01

    Proton Therapy Physics goes beyond current books on proton therapy to provide an in-depth overview of the physics aspects of this radiation therapy modality, eliminating the need to dig through information scattered in the medical physics literature. After tracing the history of proton therapy, the book summarizes the atomic and nuclear physics background necessary for understanding proton interactions with tissue. It describes the physics of proton accelerators, the parameters of clinical proton beams, and the mechanisms to generate a conformal dose distribution in a patient. The text then covers detector systems and measuring techniques for reference dosimetry, outlines basic quality assurance and commissioning guidelines, and gives examples of Monte Carlo simulations in proton therapy. The book moves on to discussions of treatment planning for single- and multiple-field uniform doses, dose calculation concepts and algorithms, and precision and uncertainties for nonmoving and moving targets. It also exami...

    Objective Recent reviews on music therapy for people with dementia have been limited to attempting to evaluate whether it is effective, but there is a need for a critical assessment of the literature to provide insight into the possible mechanisms of actions of music therapy. This systematic review......, five studies investigated hormonal and physiological changes, and five studies focused on social and relational aspects of music therapy. The musical interventions in the studies were diverse, but singing featured as an important medium for change. Conclusions Evidence for short-term improvement...... in mood and reduction in behavioural disturbance was consistent, but there were no high-quality longitudinal studies that demonstrated long-term benefits of music therapy. Future music therapy studies need to define a theoretical model, include better-focused outcome measures, and discuss how the findings...

  14. Accelerators for Cancer Therapy

    Science.gov (United States)

    Lennox, Arlene J.

    2000-05-30

    The vast majority of radiation treatments for cancerous tumors are given using electron linacs that provide both electrons and photons at several energies. Design and construction of these linacs are based on mature technology that is rapidly becoming more and more standardized and sophisticated. The use of hadrons such as neutrons, protons, alphas, or carbon, oxygen and neon ions is relatively new. Accelerators for hadron therapy are far from standardized, but the use of hadron therapy as an alternative to conventional radiation has led to significant improvements and refinements in conventional treatment techniques. This paper presents the rationale for radiation therapy, describes the accelerators used in conventional and hadron therapy, and outlines the issues that must still be resolved in the emerging field of hadron therapy.

    2000-01-01

    Full Text Available Con el fin de explicar las modificaciones en la secreción de LH que se observan durante el ayuno en animales, se ha postulado que señales metabólicas de origen sanguíneo serían captadas por sensores a nivel central o periférico, los cuales transmitirían la información sobre el estatus metabólico hacia las neuronas GnRH para producir ajustes en su secreción y consecuentemente en la de LH. Entre estas señales se ha postulado a la insulina. Es poco conocido el posible rol de la insulina como señal metabólica en ovejas prepúberes en estados de balance energético negativo experimental como por ejemplo el ayuno. La acción de la insulina en estas condiciones experimentales podría estar asociada a la sensibilidad tisular a la insulina. El objetivo del presente trabajo fue establecer la sensibilidad a la insulina en ovejas prepúberes de 16 semanas antes, durante y después de un ayuno corto de 8 días. Para ello, 6 ovejas Suffolk Down prepúberes recibieron un bolo de insulina (0,1 UI/kg PV endovenosa el día anterior (día 0, el día 1 y el día 8 de ayuno y 24 horas después de finalizado el ayuno (día 9.

Se midió también la LH plasmática a los 0,10,20,40 y 60 min después de la administración de insulina en cada uno de los días del ensayo para determinar el efecto de la insulina sobre la secreción aguda de LH. Las concentraciones basales de cortisol se midieron los días 0, 1, 8 y 9 del ensayo para reconocer el posible estrés inducido por el ayuno. EL ISI no cambió entre el día 0 y 1

    Field, Tiffany

    2016-08-01

    In this review, massage therapy has been shown to have beneficial effects on varying conditions including prenatal depression, preterm infants, full-term infants, autism, skin conditions, pain syndromes including arthritis and fibromyalgia, hypertension, autoimmune conditions including asthma and multiple sclerosis, immune conditions including HIV and breast cancer and aging problems including Parkinson's and dementia. Although many of the studies have involved comparisons between massage therapy and standard treatment control groups, several have compared different forms of massage (e.g. Swedish versus Thai massage), and different active therapies such as massage versus exercise. Typically, the massage therapy groups have experienced more positive effects than the control or comparison groups. This may relate to the massage therapy providing more stimulation of pressure receptors, in turn enhancing vagal activity and reducing cortisol levels. Some of the researchers have assessed physical, physiological and biochemical effects, although most have relied exclusively on self-report measures. Despite these methodological problems and the dearth of research from the U.S., the massage therapy profession has grown significantly and massage therapy is increasingly practiced in traditional medical settings, highlighting the need for more rigorous research.

    Schizophrenia is a devastating and poorly understood disease for which the only accepted therapy is nonspecific antipsychotic and anti-seizure medication. This article summarizes the evidence that certain vitamin deficiencies likely worsen the symptoms of schizophrenia, and the evidence that large doses of certain vitamins could improve the core metabolic abnormalities that predispose some people to develop it; it recounts the history of a controversial vitamin-based therapy for schizophrenia called orthomolecular psychiatry; and it concludes by advocating a process for discovering promising new schizophrenia therapies that involves small, carefully conducted clinical trials of nutrient combinations in appropriately selected patients.

    We offer a view of the nature and role of client-therapist collaboration in experiential psychotherapy, focusing on Gestalt and emotion-focused therapy (EFT). We distinguish between the necessary condition of mutual trust (the emotional bond between client and therapist) and effective collaboration (regarding the goals and tasks of therapy). Using a case study of experiential therapy for social anxiety, we illustrate how the development of collaboration can be both complex and pivotal for therapeutic success, and how it can involve client and therapist encountering one another through taking risks by openly and nonjudgementally disclosing difficult experiences in order to enrich and advance the work.

Whenever possible, the separate toxicity of chemotherapy, irradiation, and combination therapy is addressed. However, it is not always possible to quantitate specifically such reactions in the face of multiple drug therapy, which may enhance radiation injury or reactivate prior radiation injury. Prior detailed reviews have provided important sources of information concerning radiation injury for this more general discussion. The information provided will assist both the clinician and the radiologist in the recognition of early and late complications of therapy in pediatric oncology

    Electroconvulsive therapy (ECT) remains an extremely valuable tool in the treatment of certain psychiatric disorders. Despite the sensationalism of the past decade, ECT is the treatment of choice in severe depression that is unresponsive to other therapies or in patients who are overtly suicidal. In addition, ECT is particularly valuable in the elderly population, who are at risk for serious complications from the side effects associated with drug therapy. This report describes a case of recurrent depression in which ECT was successfully used. PMID:2072186

    Manual therapy includes methods where the therapist's hands are used to stretch, mobilize or manipulate the spinal column, paravertebral structures or extremity joints. The aims of these methods are to relieve pain and improve function. In Norway only specially qualified physiotherapists and chiropractors are authorized to perform manipulation of joints (high velocity thrust techniques). To become a qualified manual therapist in Norway one must have a minimum of two years of clinical practice as physiotherapist followed by two year full time postgraduate training in manual therapy (a total of six years). Historically the Norwegian manual therapy system was developed in the 1950s by physiotherapists and medical doctors in England (James Cyriax and James Mennell) and Norway. As a result doctors allowed physiotherapists to use manipulation as a treatment method of both spinal and peripheral joints. In 1957 the Norwegian health authorities introduced reimbursement for manual therapy performed by physiotherapists.

    Full Text Available Photodynamic therapy is a new modality of therapy being used for the diagnosis and treatment of many tumors. It is now being increasingly used for skin tumors and other dermatological disorders. With its range of application it is certainly the therapy of the future. Its mechanism of action is by the Type II photo-oxidative reaction. The variables are the photosensitizer, the tissue oxygenation and the light source. It has been used to treat various disorders including Bowen′s disease, actinic keratoses, squamous cell carcinomas, basal cell carcinomas, and mycosis fungoides. The side-effects are fortunately mild and transient. Newer photosensitisers like methyl aminolevulinate hold a lot of promise for better therapy.

    Down through the ages, music has been universally valued for its therapeutic properties based on the psychological and physiological responses in humans. However, the underlying mechanisms of the psychological and physiological responses to music have been poorly identified and defined. Without clarification, a concept can be misused, thereby diminishing its importance for application to nursing research and practice. The purpose of this article was for the clarification of the concept of music therapy based on Walker and Avant's concept analysis strategy. A review of recent nursing and health-related literature covering the years 2007-2014 was performed on the concepts of music, music therapy, preferred music, and individualized music. As a result of the search, the attributes, antecedents, and consequences of music therapy were identified, defined, and used to develop a conceptual model of music therapy. The conceptual model of music therapy provides direction for developing music interventions for nursing research and practice to be tested in various settings to improve various patient outcomes. Based on Walker and Avant's concept analysis strategy, model and contrary cases are included. Implications for future nursing research and practice to use the psychological and physiological responses to music therapy are discussed. PMID:27024999

  14. Psychodynamic Music Therapy

    Directory of Open Access Journals (Sweden)

    Jinah Kim

    2016-07-01

    Full Text Available This paper introduces and explores the basic principles of psychodynamic approaches in music therapy. Music is used as a means to explore both conscious and unconscious issues as well as the internal world of the individuals involved in music therapy. However, the focus of therapy is on therapeutic relationship, especially the dynamics of transference and counter-transference between the client and the music therapist. Musical experiences, such as music listening, songs, and improvisation, can be used to facilitate the therapeutic processes, and to achieve individualized therapeutic goals. When clinically appropriate, verbal processing might play as crucial a role as the musical processing. Practitioners of psychodynamic approaches often strive to gain meaning and in-depth understandings from therapeutic experiences, and the approach is therefore suitable for individuals who are ready to work through their personal issues within a therapeutic relationship. Various approaches and techniques have been developed in psychotherapy as well as in music therapy. Perhaps the only commonality in these approaches is that psychodynamic thinking informs the direction of the therapy and therapeutic processes. Clinical vignettes will be introduced within the article to highlight a triadic dynamic—the client, the music therapist, and the music—in order to illustrate the core aspects of psychodynamic music therapy.

    Full Text Available Cellular therapy now offer promise of potential adjunct therapeutic options for treatment of drug-resistant tuberculosis (TB. We review here the role of Mesenchymal stromal cells, (MSCs, as well as other immune effector cells in the therapy of infectious diseases with a focus on TB. MSCs represent a population of tissue-resident non-hematopoietic adult progenitor cells which home into injured tissues increase the proliferative potential of broncho-alveolar stem cells and restore lung epithelium. MSCs have been shown to be immune-modulatory and anti-inflammatory mediated via cell-cell contacts as well as soluble factors. We discuss the functional profile of MSCs and their potential use for adjunct cellular therapy of multi-drug resistant TB, with the aim of limiting tissue damage, and to convert unproductive inflammatory responses into effective anti-pathogen directed immune responses. Adjunct cellular therapy could potentially offer salvage therapy options for patients with drug-resistant TB, increase clinically relevant anti-M.tuberculosis directed immune responses and possibly shorten the duration of anti-TB therapy.

    With increased survival of increasing numbers of cancer patients as a result of therapy, the consequences, early and late, of the therapies must be realized. It is the treating physician's duty to preserve as much reproductive potential as possible for patients, consistent with adequate care. With radiotherapy this means shielding the gonads as much as possible, optimal but not excessive doses and fields, oophoropexy, or sperm collection and storage prior to irradiation. With chemotherapy it means the shortest exposure to drugs consistent with best treatment and prior to therapy the collection and storage of sperm where facilities are available. At present this is still an experimental procedure. Artificial insemination for a couple when the male has received cancer therapy is another alternative. Finally, it is the responsibility of physicians caring for patients with neoplasms to be knowledgeable about these and all other effects of therapy so that patients may be counseled appropriately and understand the implications of therapy for their life.

    Full Text Available Depigmentation therapy in vitiligo is an option in those with extensive vitiligo who have failed to respond to medical therapy and have obvious cosmetic disfigurement due to intervening patchy pigmented areas. Various aspects of this therapy such as the cost, treatment time, course, permanency of depigmentation, side effects, and the possibility of repigmentation should first be discussed with the patient. At present, there is no ideal depigmenting therapy available, but many agents in the market have been in use for many years. Monobenzyl ether of hydroquinone (MBEH is the mainstay and Food and Drug Administration (FDA approved in USA but takes many months to depigment and is associated with local side effects and risk of repigmentation. Other agents which are also used are 4-methoxy phenol and 88% phenol. Physical therapies for depigmentation include Q-switched ruby and alexandrite lasers and cryotherapy. Second-line agents which can be explored for depigmentation include imatinib mesylate, imiquimod, and diphencyprone. Many possible experimental agents are being explored like various phenol derivatives, melanoma vaccines, interferon gamma, busulfan, etc. A major lacuna still exists in this area and a lot more research is desirable to give satisfactory cosmesis to these patients with extensive vitiligo.

    Schaller, M; Belge, K

    2013-07-01

    The only medication which is authorized for therapy of rosacea is doxycycline. It is usually administered at a dose of 40-100 mg daily for 3-6 months. In case of a lack of efficacy or in case of contraindications (e.g. pregnancy, children below 8 years), azithromycin or metronidazole are alternative systemic therapies. Those forms of rosacea which involve hyperplasia of sebaceous glands respond well to retinoids such as isotretinoin. Dapsone has been successfully used for the treatment of granulomatous rosacea and rosacea fulminans. Erythema can be reduced by use of beta blockers. If patients do not respond to various therapies or if they are immunocompromised, the differential diagnosis of demodicosis should be considered; here the treatment is oral ivermectin. Some forms of rosacea (rosacea fulminans and granulomatous rosacea) may be treated initially with oral corticosteroids. Ophthalmic rosacea is treated topically as well as with tetracyclines or macrolides.

    George, Rosalyn; Clarke, Shari; Thiboutot, Diane

    2008-09-01

    Acne affects more than 40 million people, of which more than half are women older than 25 years of age. These women frequently fail traditional therapy and have high relapse rates even after isotretinoin. Recent advances in research have helped to delineate the important role hormones play in the pathogenesis of acne. Androgens such as dihydrotestosterone and testosterone, the adrenal precursor dehydroepiandrosterone sulfate, estrogens, growth hormone, and insulin-like growth factors may all contribute to the development of acne. Hormonal therapy remains an important part of the arsenal of acne treatments available to the clinician. Women dealing with acne, even those without increased serum androgens, may benefit from hormonal treatments. The mainstays of hormonal therapy include oral contraceptives and antiandrogens such as spironolactone, cyproterone acetate, or flutamide. In this article, we discuss the effects of hormones on the pathogenesis of acne, evaluation of women with suspected endocrine abnormalities, and the myriad of treatment options available.

    The Enterobacteriaceae are a class of gram-negative facultative anaerobic rods, which can cause a variety of diseases, such as bacteremia, septic arthritis, endocarditis, osteomyelitis, lower respiratory tract infections, skin and soft-tissue infections, urinary tract infections, intra-abdominal infections and ophthalmic infections, in humans, poultry, animals and fish. Disease caused by Enterobacteriaceae cause the deaths of millions of people every year, resulting in enormous economic loss. Drug treatment is a useful and efficient way to control Enterobacteriaceae infections. However, with the abuse of antibiotics, drug resistance has been found in growing number of Enterobacteriaceae infections and, as such, there is an urgent need to find new methods of control. Bacteriophage therapy is an efficient alternative to antibiotics as it employs a different antibacterial mechanism. This paper summarizes the history of bacteriophage therapy, its bacteriallytic mechanisms, and the studies that have focused on Enterobacteriaceae and bacteriophage therapy.

    An investigation was made of applying pulsed (lambda) equals 0.89 micrometers laser radiation in the treatment for early diagnosed periodontitis. The investigation was made on 65 patients (47 patients constituted the experimental group and 18 patients constituted a control group) affected by periodontitis. Clinical and functional tests revealed that laser therapy produced a string effect on the course of the illness. It reduced bleeding, inflammation, and pruritus. However, it did not produce an affect on electroexcitation. Biomicroscopic examinations and periodontium rheography revealed that the gingival blood flow became normal after the course of laser therapy. The capillary permeability and venous congestion decreased, which was confirmed by the increased time of vacuum tests, raised gingival temperature, reduced tissue clearance, and increased oxygen tension. Apart from that, laser therapy subsided fibrinolysis, proteolytic tissue activity, and decreased the exudative inflammation of periodontium.

    1986-12-01

    Therapy and suggestion are closely related. That is clear for the ancient time: primitive medicine gives a good place to the Word. In plant, animal or mineral remedies, the suggestion is clearly preponderant. Towards the end of the 19th century, the "Ecole de Nancy" sets up a real theory of the suggestion, and Bernheim, its leader, bases hypnosis, then psychotherapy on this concept. Thereafter Coué will bring up the "conscious autosuggestion". Today, despite the progress of scientific medicine, the part of suggestion is still very important in medical therapy (with or without drugs), or in chirurgical therapy; this part is also very important in psychotherapies, whatever has been said in this field. This has to be known and used consciously in the doctor-patient relation, which is always essential in the therapeutic effectiveness.

    "Gene therapy" can be defined as the transfer of genetic material into a patient's cells for therapeutic purposes. To date, a diverse and creative assortment of treatment strategies utilizing gene therapy have been devised, including gene transfer for modulating the immune system, enzyme prodrug ("suicide gene") therapy, oncolytic therapy, replacement/therapeutic gene transfer, and antisense therapy. For malignant glioma, gene-directed prodrug therapy using the herpes simplex virus thymidine kinase gene was the first gene therapy attempted clinically. A variety of different strategies have now been pursued experimentally and in clinical trials. Although, to date, gene therapy for brain tumors has been found to be reasonably safe, concerns still exist regarding issues related to viral delivery, transduction efficiency, potential pathologic response of the brain, and treatment efficacy. Improved viral vectors are being sought, and potential use of gene therapy in combination with other treatments is being investigated.

    Full Text Available Gene therapy "the use of genes as medicine" involves the transfer of a therapeutic or working copy of a gene into specific cells of an individual in order to repair a faulty gene copy. The technique may be used to replace a faulty gene, or to introduce a new gene whose function is to cure or to favorably modify the clinical course of a condition. The objective of gene therapy is to introduce new genetic material into target cells while causing no damage to the surrounding healthy cells and tissues, hence the treatment related morbidity is decreased. The delivery system includes a vector that delivers a therapeutic gene into the patient′s target cell. Functional proteins are created from the therapeutic gene causing the cell to return to a normal stage. The vectors used in gene therapy can be viral and non-viral. Gene therapy, an emerging field of biomedicine, is still at infancy and much research remains to be done before this approach to the treatment of condition will realize its full potential.

    Full Text Available With an incidence that is increasing at 2–5% per year, cutaneous melanoma is an international scourge that disproportionately targets young individuals. Despite much research, the treatment of advanced disease is still quite challenging. Immunotherapy with high-dose interferon-α2b or interleukin-2 benefits a select group of patients in the adjuvant and metastatic settings, respectively, with significant attendant toxicity. Advances in the biology of malignant melanoma and the role of immunomodulatory therapy have produced advances that have stunned the field. In this paper, we review the data for the use of interferon-α2b in various dosing ranges, vaccine therapy, and the role of radiotherapy in the adjuvant setting for malignant melanoma. Recent trials in the metastatic setting using anticytoxic T-lymphocyte antigen-4 (anti-CTLA-4 monoclonal antibody therapy and BRAF inhibitor therapy have demonstrated clear benefit with prolongation of survival. Trials investigating combinations of these novel agents with existing immunomodulators are at present underway.

    Full Text Available Schizophrenia is one of the most severe mental disorders. Despite significant advances in pharmacotherapy, treatment remains sub-optimal, with many patients having persisting deficits, especially in cognitive and social functioning. Yoga as a therapy has proven to be effective as a sole or additional intervention in psychiatric disorders such as depression and anxiety. Recently, there has been significant interest in the application of yoga therapy in psychosis and schizophrenia. To review a the evidence for the use of yoga therapy in patients with schizophrenia b studies which have been done in this area, c the barriers for reaching yoga to patients, and d future directions, an English language literature search of PubMed/MEDLINE, Google Scholar, and EBSCO as well as grey literature was done. Research reports have demonstrated the feasibility and efficacy of yoga as an add-on therapy in schizophrenia, particularly in improving negative symptomatology and social cognition. However, the biological underpinnings of this effect remain unclear, although there are some indications that hormones like oxytocin may contribute to the changes in social cognition.

    Full Text Available Yoga is a useful supportive intervention for a broad range of pain-associated diseases. It is often recommended as therapy for a variety of medical conditions and it is rising popularity as therapy (Verrastro, 2014. Yoga is a system of movement and breathing exercises meant to foster mind-body connection. It creates inner, physical and emotional balance through the use of postures, called asanas, combined with breathing techniques or pranayama (Posadzki et al, 2011. Benefits are found in different areas: Physical benefits (e.g.: flexibility, coordination, strength, endurance mental benefits (e.g.: to develop greater awareness, diminish anxiety and reduction of distress, positive behavioural changes, improvement mood, facilitate positive emotions and optimism, broaden cognitive processes and enhance self- efficacy for pain control or social (e.g.: to reduce isolation, to foster social networks and reinforce social support. Researches show that even despite persistent pain symptoms, patients recognize that they are able to be physically active, they experience higher self-competence and self-awareness, which contributes to higher quality of life. Moreover, yoga therapy is a safe and beneficial supportive treatment, relatively cheap, it requires just the motivation of patients (Posadzki et al, 2011; Büsing et al, 2012 and a good professional support.

    Schema therapy is an integrative approach of psychotherapy developed by Jeffrey E. Young. Its aim is to help clients explore and understand their deep emotional needs and meet them in a healthy manner. It is suitable for complex pathologies, such as comorbidities and personality disorders. In sex therapy, schema therapy can serve as a method for a deep, evidence-based, integrative conceptualization of a client's difficulties and needs. However, its principles have never been demonstrated in sex therapy. In this paper, we briefly review schema therapy and introduce schema domains. We bring a case study of a couple undergoing sex therapy from the cognitive-behavioral perspective. We then return to the same case study, in order to demonstrate the usefulness of a schema therapy conceptualization.

    Full Text Available The treatment of psoriasis has undergone a revolution with the advent of biologic therapies, including infliximab, etanercept, adalimumab, efalizumab, and alefacept. These medications are designed to target specific components of the immune system and are a major technological advancement over traditional immunosuppressive medications. These usually being well tolerated are being found useful in a growing number of immune-mediated diseases, psoriasis being just one example. The newest biologic, ustekinumab, is directed against the p40 subunit of the IL-12 and IL-23 cytokines. It has provided a new avenue of therapy for an array of T-cell-mediated diseases. Biologics are generally safe; however, there has been concern over the risk of lymphoma with use of these agents. All anti-TNF-α agents have been associated with a variety of serious and "routine" opportunistic infections.

    Hormones, in particular androgen hormones, are the main cause of acne in men, women, children and adults, in both normal states and endocrine disorders. Therefore, the use of hormonal therapies in acne is rational in concept and gratifying in practice. Although non-hormonal therapies enjoy wide usage and continue to be developed, there is a solid place for hormonal approaches in women with acne, especially adult women with persistent acne. This review covers the physiological basis for hormonal influence in acne, the treatments that are in use today and those that show promise for the future.

    1991-06-01

    Apart from its use in endocrinology and rheumatology, therapeutic nuclear medicine is developing rapidly as an additional treatment modality in oncology. Many different specific tumour-seeking radiopharmaceuticals are being applied both for diagnostic scintigraphy and treatment, using multiple routes and mechanisms to target radionuclides at tumours. After a brief introduction of some basic principles of radionuclide targeting, the therapeutic radiopharmaceuticals available are reviewed according to the accumulation site in relation to the cell nucleus; the results of their current clinical use for therapy are also reviewed. The response observed to a number of these applications, the non-invasiveness of the procedure and the relative lack of toxicity and late effects in comparison with chemotherapy and external beam radiotherapy make radionuclide therapy an attractive and realistic alternative in the management of malignant disease, as well as in the treatment of a few benign disorders.

    After four decades of research of photobiomodulation phenomena in mammals in vitro and in vivo, a solid foundation is created for the use of photobiomodulation in regenerative medicine. Significant accomplishments are achieved in animal models that demonstrate opportunities for photo-regeneration of injured or pathological tissues: skin, muscles and nerves. However, the use of photobiomodulation in clinical studies leads to controversial results while negative or marginal clinical efficacy is reported along with positive findings. A thor ough analysis of requirements to the optical parameters (dosimetry) for high efficacy in photobimodulation led us to the conclusion that there are several misconceptions in the clinical applications of low level laser therapy (LLLT). We present a novel appr oach of regenerative photonic therapy (RPT) for tissue healing and regeneration that overcomes major drawbacks of LLLT. Encouraging clinical results on RPT efficacy are presented. Requirements for RPT approach and vision for its future development for tissue regeneration is discussed.

    An efficient therapy for cough usually requires identification and treatment of the underlying disease, like asthma. However an underlying disease in cough is not found in all cases and conventional treatment of the underlying disease is ineffective against cough. Drug therapy options are available also for these situations. Honey or menthol can be tried for cough associated with respitatory infections, antihistamines for cough associated with allergic rhinitis, blockers of the leukotriene receptor or muscarinic receptor for asthma-associated cough and morphine for cough associated with a malignant disease. Menthol, blockers of the muscarinic receptor, or dextrometorphan can be tried for prolonged idiopathic cough. Codeine is not necessary in the treatment of cough. Refraining from drug treatment should always be considered. PMID:27089619

The ubiquitin-proteasome and the Akt/mammalian target of rapamycin (mTOR pathways are examples of pathological mechanisms that are being targeted in drug development efforts. Bortezomib (a small molecule protease inhibitor and the mTOR inhibitors temsirolimus, everolimus, and ridaforolimus are some of the targeted therapies currently being studied in the treatment of aggressive, relapsed/refractory lymphoma. This review will discuss the rationale for and summarize the reported findings of initial and ongoing investigations of mTOR inhibitors and other small molecule targeted therapies in the treatment of lymphoma.

    2007-01-01

    Mucopolysaccharidoses (MPS) are due to deficiencies in activities of lysosomal enzymes that degrade glycosaminoglycans. Some attempts at gene therapy for MPS in animal models have involved intravenous injection of vectors derived from an adeno-associated virus (AAV), adenovirus, retrovirus or a plasmid, which primarily results in expression in liver and secretion of the relevant enzyme into blood. Most vectors can correct disease in liver and spleen, although correction in other organs includ...

    Rosacea is a common skin disorder with multiple symptoms. The emergence of research that furthers understanding of pathophysiological mechanisms has created new targets for disease treatment. Specifically, there is a need for new treatments that address the various erythematic symptoms associated with rosacea. Systemic and topical therapies have both yielded positive results in treating rosacea with various medications. Subantimicrobial-dose doxycycline is one such promising treatment. Development of novel products in the near future should help achieve more satisfactory outcomes for patients.

    Folk therapy (often simply old wives' tales put into practice) is usually innocuous and may be effective for some patients because of either its content or its placebo effect. However, some household medications may be deadly. Reported is the use of Azarcon for "empacho" among Hispanic families. Azarcon has been linked to cases of severe lead poisoning. Screening among children for increased erythrocyte protoporphyrin and blood lead is recommended.

Nur bei der Hälfte der Patienten mit SE besteht zuvor eine Epilepsie; die meisten Fälle sind symptomatisch, wobei Schädel- Hirn-Traumata, zerebrovaskuläre Erkrankungen, ZNS-Infektionen und metabolische Ursachen führend sind. Bei Patienten mit vorbestehender Epilepsie lässt sich eine frühe Phase des GKSE erkennen, in der die Anfälle crescendoartig zunehmen, bis sie in kontinuierliche Anfallsaktivität münden (etablierte Phase. Das Management eines GKSE verlangt rasches und beherztes Vorgehen. Neben der sofort einzuleitenden Therapie muss gleichzeitig die artdiagnostische Zuordnung des SE und die Ursache erkannt und behandelt werden. Als Therapie der ersten Wahl sind Benzodiazepine etabliert, wobei intravenösem (i.v. Lorazepam gegenüber Diazepam der Vorzug zu geben ist.

    Full Text Available Rebecca Pavlos, Elizabeth J PhillipsInstitute for Immunology and Infectious Diseases, Murdoch University, Murdoch, Western Australia, AustraliaAbstract: Antiretroviral therapy (ART has evolved considerably over the last three decades. From the early days of monotherapy with high toxicities and pill burdens, through to larger pill burdens and more potent combination therapies, and finally, from 2005 and beyond where we now have the choice of low pill burdens and once-daily therapies. More convenient and less toxic regimens are also becoming available, even in resource-poor settings. An understanding of the individual variation in response to ART, both efficacy and toxicity, has evolved over this time. The strong association of the major histocompatibility class I allele HLA-B*5701 and abacavir hypersensitivity, and its translation and use in routine HIV clinical practice as a predictive marker with 100% negative predictive value, has been a success story and a notable example of the challenges and triumphs in bringing pharmacogenetics to the clinic. In real clinical practice, however, it is going to be the exception rather than the rule that individual biomarkers will definitively guide patient therapy. The need for individualized approaches to ART has been further increased by the importance of non-AIDS comorbidities in HIV clinical practice. In the future, the ideal utilization of the individualized approach to ART will likely consist of a combined approach using a combination of knowledge of drug, virus, and host (pharmacogenetic and pharmacoecologic [factors in the individual's environment that may be dynamic over time] information to guide the truly personalized prescription. This review will focus on our knowledge of the pharmacogenetics of the efficacy and toxicity of currently available antiretroviral agents and the current and potential utility of such information and approaches in present and future HIV clinical care.Keywords: HIV

    Multiple Myeloma(MM)is characterised by the accumulation of malignanat plasma cells in the bone marrow producing a monocolonal immungoglobulin.The standard conventiona therapy in the combination of melphalan and prednisone resulting in a response rate of 40%-60% and in a median survival time of approximately 3 years.In order to improve the therapeutic efficacy va rious combination regimens have been tested.Most randomized trials have frailed to show a significant improvement in survival time when combination chemotherapy is used instead of melphalan with or without prednisone.The benefit of maintenance therapy with interferon-alpha has been demonstrated.The toxicity of interferon-alpha,which may reduce the quality of life,should be considered.Recently,myeloma-treatment has been modified.High-dose chemotherapy accompaniced by hematopoietic stem-cell support via autologous transplant is recommended up to the age of 65-70 years.First results from a French study comparing single versus double autologous transplantaiton have shown a benefit in terms of event-free survival for the sequential approach.Vaccinations as an adoptive immuntherapy to treat minimal residual dsease are umder way.The mortality rate of allogeneic transplantation of hemaatopoietic stem cells has been reduced in the last 5 years.The use of reduced conditioning regimens or the partial depletion of T cells in peripheral blood stem cell transplants in an effort to decrease transplant related mortality are promising approaches.Thalidomide and its derivates are a new class of agents with independent anti-tumour activity in MM.Encouraging results with this antiangiogenic therapy in phase Ⅱ trials have been reported.Supportive therapies,such as the treatment of anaemia with erythropoietin,the management of renal failure and the use of bisphosphonates,improve the life quality of MM patients.

    Metronidazole and azelaic acid are the only topical medications approved for rosacea. All other topical treatments for rosacea and its special forms are used off-label. Topical steroids are not indicated in rosacea, because of their side effects (induction of steroid rosacea, high risk of facial skin atrophy, and high risk of rebound after cessation of therapy). Topical as well as systemic steroids are allowed only as initial and short term therapy for acute forms of rosacea (e.g. rosacea fulminans). Papular and pustular rosacea is the major indication for topical therapy. Sebaceous gland and connective tissue hyperplasia in glandular-hypertrophic rosacea as well as erythema in erythematous rosacea do not respond well to topical measures. A new active substance, the alpha-2-adrenoreceptor agonist brimonidine, will be approved soon for the topical treatment of erythema in rosacea. All severe forms of rosacea should initially be treated with a combination of topical and systemic agents. After improvement of the clinical symptoms, topical treatment alone is usually adequate to maintain the control.

    Ototoxicity is a well-established toxicity associated with a subgroup of antineoplastic therapies that includes platinum chemotherapy, radiation or surgery involving the ear and auditory nerve, and supportive care agents such as aminoglycoside antibiotics and loop diuretics. The reported prevalence of ototoxicity in patients who have received potentially ototoxic therapy ranges from 4% to 90% depending on factors such as age of the patient population, agent(s) used, cumulative dose, and administration techniques. The impact of ototoxicity on subsequent health-related and psychosocial outcomes in these patients can be substantial, and the burden of morbidity related to ototoxic agents is particularly high in very young children. Considerable interindividual variability in the prevalence and severity of ototoxicity has been observed among patients receiving similar treatment, suggesting genetic susceptibility as a risk factor. The development and testing of otoprotective agents is ongoing; however, to the author's knowledge, no US Food and Drug Administration-approved otoprotectants are currently available. Prospective monitoring for ototoxicity allows for comparison of auditory outcomes across clinical trials, as well as for early detection, potential alterations in therapy, and auditory intervention and rehabilitation to ameliorate the adverse consequences of hearing loss.

    Konopka, K; Goslinski, T

    2007-08-01

    Photodynamic therapy (PDT), also known as photoradiation therapy, phototherapy, or photochemotherapy, involves the use of a photoactive dye (photosensitizer) that is activated by exposure to light of a specific wavelength in the presence of oxygen. The transfer of energy from the activated photosensitizer to available oxygen results in the formation of toxic oxygen species, such as singlet oxygen and free radicals. These very reactive chemical species can damage proteins, lipids, nucleic acids, and other cellular components. Applications of PDT in dentistry are growing rapidly: the treatment of oral cancer, bacterial and fungal infection therapies, and the photodynamic diagnosis (PDD) of the malignant transformation of oral lesions. PDT has shown potential in the treatment of oral leukoplakia, oral lichen planus, and head and neck cancer. Photodynamic antimicrobial chemotherapy (PACT) has been efficacious in the treatment of bacterial, fungal, parasitic, and viral infections. The absence of genotoxic and mutagenic effects of PDT is an important factor for long-term safety during treatment. PDT also represents a novel therapeutic approach in the management of oral biofilms. Disruption of plaque structure has important consequences for homeostasis within the biofilm. Studies are now leading toward selective photosensitizers, since killing the entire flora leaves patients open to opportunistic infections. Dentists deal with oral infections on a regular basis. The oral cavity is especially suitable for PACT, because it is relatively accessible to illumination. PMID:17652195

Therapeutic options, when organ failure occurs, are frequently nonspecific and mostly directed towards supporting vital function. In these scenarios, the kidneys are almost always involved and, therefore, renal replacement therapies have become a common routine practice in critically ill patients with acute kidney injury. Recent technological improvement has led to the production of safe, versatile and efficient dialysis machines. In addition, emerging evidence may allow better individualization of treatment with tailored prescription depending on the patients' clinical picture (e.g. sepsis, fluid overload, pediatric). The aim of the present review is to give a general overview of current practice in renal replacement therapies for critically ill patients. The main clinical aspects, including dose prescription, modality of dialysis delivery, anticoagulation strategies and timing will be addressed. In addition, some technical issues on physical principles governing blood purification, filters characteristics, and vascular access, will be covered. Finally, a section on current standard nomenclature of renal replacement therapy is devoted to clarify the "Tower of Babel" of critical care nephrology. PMID:26918174

    Full Text Available Introduction: Exposure with response prevention is an effective treatment for all anxiety disorders. According to the behavioral learning theories, fears which are conditioned via classical conditioning are reinforced by respondent conditioning. Avoidance and safety seeking behaviors prevent disconfirmation of anxious beliefs. In exposure client faces stimulates or cues that elicit fear or distress, by this avoidance is inhibited. Clients are also encouraged to resists performing safety seeking behaviors or rituals that they utilize to reduce fear or distress. Accomplishing these habituation or extinction is achieved. In addition to this clients learn that feared consequences does not realize or not harmful as they believed by experiencing. Emotional processing is believed to be the mechanism of change in exposure.Objective: The aim of this review is to provide a definition of exposure and its effectiveness briefly, and describe how to implement exposure, its steps and remarkable aspects using. Exposure therapies and treatments that involve exposure are proved to be effective in all anxiety disorders. Exposure therapy can be divided in three parts: Assessment and providing a treatment rationale, creating an exposure hierarchy and response prevention plan, implementing exposure sessions. Clients must also continue to perform exposure between sessions. Therapy transcripts are also provided to exemplify these parts. Conclusion: Exposure with response prevention is a basic and effective technique. Every cognitive behavior therapist must be able to implement this technique and be cognizant of pearls of this procedure.

    The central nervous system of vertebrates, even when immature, displays extraordinary resistance to damage by microscopically narrow, multiple, parallel, planar beams of x rays. Imminently lethal gliosarcomas in the brains of mature rats can be inhibited and ablated by such microbeams with little or no harm to mature brain tissues and neurological function. Potentially palliative, conventional wide-beam radiotherapy of malignant brain tumors in human infants under three years of age is so fraught with the danger of disrupting the functional maturation of immature brain tissues around the targeted tumor that it is implemented infrequently. Other kinds of therapy for such tumors are often inadequate. We suggest that microbeam radiation therapy (MRT) might help to alleviate the situation. Wiggler-generated synchrotron x-rays were first used for experimental microplanar beam (microbeam) radiation therapy (MRT) at Brookhaven National Laboratory's National Synchrotron Light Source in the early 1990s. We now describe the progress achieved in MRT research to date using immature and adult rats irradiated at the European Synchrotron Radiation Facility in Grenoble, France, and investigated thereafter at the Institute of Pathology of the University of Bern.

    The purpose of the Music Therapy Career Aptitude Test (MTCAT) was to measure the affective domain of music therapy students including their self-awareness as it relates to the music therapy career, value in human development, interest in general therapy, and aptitude for being a professional music therapist. The MTCAT was administered to 113 music therapy students who are currently freshman or sophomores in an undergraduate music therapy program or in the first year of a music therapy master's equivalency program. The results of analysis indicated that the MTCAT is normally distributed and that all 20 questions are significantly correlated with the total test score of the MTCAT. The reliability of the MTCAT was considerably high (Cronbach's Coefficient Alpha=0.8). The criterion-related validity was examined by comparing the MTCAT scores of music therapy students with the scores of 43 professional music therapists. The correlation between the scores of students and professionals was found to be statistically significant. The results suggests that normal distribution, internal consistency, homogeneity of construct, item discrimination, correlation analysis, content validity, and criterion-related validity in the MTCAT may be helpful in predicting music therapy career aptitude and may aid in the career decision making process of college music therapy students.

Prostate cancer (PCa) is one of the most frequently diagnosed cancers in men. Several treatment options with different therapeutic approaches exist, including HIFU for localized PCa that has been in use for over 15 years. Since the early 2000s, two systems have been marketed for this application, and other devices are currently in clinical trials. HIFU treatment can be used either alone or in combination with (before- or after-) external beam radiotherapy (EBRT) (before or after HIFU) and can be repeated multiple times. HIFU treatment is performed under real-time monitoring with ultrasound or guided by MRI. Two indications are validated today: Primary care treatment and EBRT failure. The results of HIFU for primary care treatment are similar to standard conformal EBRT, even though no randomized comparative studies have been performed and no 10-year follow up data is yet available for HIFU. Salvage HIFU after EBRT failure is increasing with oncological outcomes, similar to those achieved with surgery but with the advantage of fewer adverse effects. HIFU is an evolving technology perfectly adapted for focal treatment. Thus, HIFU focal therapy is another pathway that must be explored when considering the accuracy and reliability for PCa mapping techniques. HIFU would be particularly suited for such a therapy since it is clear that HIFU outcomes and toxicity are relative to the volume of prostate treated. PMID:26486330

    Loredan Biomedical, Inc.'s LIDO, a computerized physical therapy system, was purchased by NASA in 1985 for evaluation as a Space Station Freedom exercise program. In 1986, while involved in an ARC muscle conditioning project, Malcom Bond, Loredan's chairman, designed an advanced software package for NASA which became the basis for LIDOSOFT software used in the commercially available system. The system employs a "proprioceptive" software program which perceives internal body conditions, induces perturbations to muscular effort and evaluates the response. Biofeedback on a screen allows a patient to observe his own performance.

    Full Text Available Targeted radiotherapy is an evolving and promising modality of cancer treatment. The killing of cancer cells is achieved with the use of biological vectors and appropriate radionuclides. Among the many advantages of this approach are its selectiveness in delivering the radiation to the target, relatively less severe and infrequent side effects, and the possibility of assessing the uptake by the tumor prior to the therapy. Several different radiopharmaceuticals are currently being used by various administration routes and targeting mechanisms. This article aims to briefly review the current status of targeted radiotherapy as well as to outline the advantages and disadvantages of radionuclides used for this purpose.

    Full Text Available The search for biological antitumor agents has been pursued for over half a century. Among the biological agents which have antitumoral activity, snake and scorpion venoms have been shown to possess a wide spectrum of biological activities. Venom components exhibit an antitumoral activity by means of direct cytolytic and cytostatic effects or indirect mechanisms such as amplifying of immune response against cancerous cells. These peptides constitute a potent antitumoral activity throughout their thrapeutic usages while they cause any significant side effects. Therefore it has been emphasized that natural venom peptides or their synthetic analogues will be valuable agents in replacement of classical antineoplastic drugs in cancer therapy in the future.

    Donohue, J F; Ohar, J A

    2001-03-01

    Combination products often have useful clinical benefits in asthma. The scientific rationale for combination therapy includes the fact that different agents have complimentary modes of action. Long-acting beta(2)-agonists have effects on airway smooth muscle, and inhaled corticosteroids have potent topical antiinflammatory effect. This combination has been shown to effectively reduce exacerbations and improve symptoms. Substantial clinical trial data provide a rationale for dual-control therapy supported by basic scientific data. Another combined therapy is inhaled steroids plus leukotriene-receptor antagonists, which provides the patient with two effective therapies. Leukotriene-receptor antagonist can also be combined with antihistamines for improved asthma control. Older therapies including theophylline and controlled release albuterol have been effectively added to inhaled corticosteroids, enabling a reduction in the dose of the inhaled steroids. Many other combination therapies are presently being tested. PMID:11224725

    Full Text Available The author draws upon theory, training and clinical experience in palliative care music therapy and verbal psychoanalytic therapy. Elements common to both music and psychoanalytic therapy are explored; the centrality of listening, the boundaries and fluidity of time, the importance of containment and expression of affect, the capacity to facilitate mourning, and the inherent creativity of each. Contributions from analytic music therapy are considered. Two case vignettes are presented; the first integrates psychoanalytic thinking into music therapy work with a dying woman; the second, from verbal psychotherapy practise, illustrates mourning being facilitated by the spontaneous use of a song., The question of training music therapists to do depth work using psychoanalytic concepts is raised, particularly in respect to the use of words and recognition of transference and countertransference phenomena. Finally, the author reflects on her experience of music therapy and psychotherapy work each enriching and deepening the other.

    In the context of pre-interventional drug therapy, a premedication is given to patients who are known to have an allergy to contrast media, have renal impairment or hyperthyroidism. An already existing anticoagulation therapy, in anticipation of the planned intervention, must be reviewed and changed or even suspended as required. For peri-interventional drug therapy it is important to consider how strenuous the procedure will be as well as the general condition of the patient. Further discussion with anesthetists may be required for the planning of pain therapy or sedation during the procedure. These factors help to ensure maximum patient comfort as well as the success of the intervention. Post-interventional anticoagulation therapy, usually started peri-interventionally, plays an important role in minimizing the risk of acute thrombosis as well as in maintaining long-term functioning of the implanted material. The form of the anticoagulation therapy is set according to the type of intervention. PMID:26063076

    Radiation dose escalation and acceleration improves local control but also increases toxicity. Proton radiation is an emerging therapy for localized cancers that is being sought with increasing frequency by patients. Compared with photon therapy, proton therapy spares more critical structures due to its unique physics. The physical properties of a proton beam make it ideal for clinical applications. By modulating the Bragg peak of protons in energy and time, a conformal radiation dose with or without intensity modulation can be delivered to the target while sparing the surrounding normal tissues. Thus, proton therapy is ideal when organ preservation is a priority. However, protons are more sensitive to organ motion and anatomy changes compared with photons. In this article, we review practical issues of proton therapy, describe its image-guided treatment planning and delivery, discuss clinical outcome for cancer patients, and suggest challenges and the future development of proton therapy.

Many obesity-associated diseases require intensive medical treatment and are the cause of a large proportion of health-related expenditures in Germany. Treatment of obesity includes nutritional, exercise and behaviour therapy, usually in combination. The goal of behaviour therapy for obesity is to bring about a long-term alteration in the eating and exercise habits of overweight and obese individuals. Under certain circumstances, drug treatment may be indicated. Objectives: What is the effectiveness of behaviour therapy for obesity considering approved drugs reduce weight under medical, economic, ethical-social and legal aspects? Methods: A systematic review was conducted using relevant electronic literature databases. Publications chosen according to predefined criteria are evaluated by approved methodical standards of the evidence-based medicine systematically and qualitatively. Results: In total 18 studies, included one HTA and one meta-analysis could be identified according to the predefined inclusion criteria. Three studies compare behaviour therapy to other therapy forms (advice or instruction on nutritional changes, physical activity or a combination of the two, six studies evaluate different forms of behaviour therapy, four studies and four studies compare behaviour therapies mediated by Internet or telephone. Three studies could be identified examining the effect of the combination of behaviour and drug therapy. Furthermore one HTA and one meta-analysis could be included in the evaluation. The behaviour therapy in comparison with other therapy forms reveals a higher effectiveness. In comparison of the different therapeutic approaches of the behaviour therapy intensive behaviour therapy forms and group therapy show a higher effectiveness. Studies related to behaviour therapy based on media support demonstrate a weight reduction both through the

    Idiopathic inflammatory myopathy consists of dermatomyositis (DM), polymyositis (PM), inclusion body myositis (IBM) and necrotizing autoimmune myopathy (NAM). At all stages of myositis, physiotherapy is effective in improving muscle strength, endurance and in maintaining joint motion. In DM and PM the therapy is initiated with glucocorticosteroids. Steroid-sparing agents (azathioprine, methotrexate and cyclosporin A) are added to prevent Cushing's syndrome or an unsatisfactory response. Therapy can also be escalated with intravenous immunoglobulins. Tacrolimus and mycophenolate mofetil (MMF) were effective in small case series. Cyclophosphamide is restricted to patients not responding to previous agents. For treatment intensification immunoglobulins can also be combined with MMF. There is not enough evidence to routinely recommend rituximab. The results with TNF-alpha inhibitors and plasmapheresis were negative or inconsistent. In DM skin involvement responds to sun blockers, antimalarials, topical corticosteroids or calcineurin inhibitors. In NAM statins should be discontinued and treatment with prednisone and immunosuppressants initiated. In IBM a therapeutic trial with prednisone, methotrexate or azathioprine may be warranted, especially in cases in which the serum creatine kinase (CK) is elevated or an inflammatory infiltrate is present in the muscle biopsy.

    Treating Cushing's syndrome is very challenging and should be tailored to the patient. Surgery is considered the gold standard treatment for both pituitary adrenocorticotropic hormone (ACTH)-secreting adenomas, ectopic ACTH-secreting tumors and adrenal tumors, as the chance to be successful is high, especially for adrenal tumors, when performed in specialized centers by expert surgeons. Pituitary radiotherapy represents a second-line treatment in patients not cured with surgery, or when medical treatment is not suitable/efficacious, although the rate of cure is largely variable and achieved only in the long term, and is associated with the risk of developing secondary hypopituitarism. Several drugs, acting at the pituitary, adrenal or peripheral tissue level, are available. Medical treatment is indicated as second-line therapy for patients unsuccessfully treated with pituitary surgery, or in those awaiting radiotherapy to become effective, or prior to adrenalectomy, and as the first-line approach to prepare patients for surgery, especially those with severe comorbidities, or in those not suitable/refusing surgery. The success rate of medical therapy is variable, depending on the cause and severity of hypercortisolism, and is often associated with important side effects. PMID:27210582

    A new class of two-dimensional (2D) nanomaterial, transition metal dichalcogenides (TMDCs) such as MoS2, MoSe2, WS2, and WSe2 which have fantastic physical and chemical properties, has drawn tremendous attention in different fields recently. Herein, we for the first time take advantage of the great potential of MoS2 with well-engineered surface as a novel type of 2D nanocarriers for gene delivery and therapy of cancer. In our system, positively charged MoS2-PEG-PEI is synthesized with lipoic acid-modified polyethylene glycol (LA-PEG) and branched polyethylenimine (PEI). The amino end of positively charged nanomaterials can bind to the negatively charged small interfering RNA (siRNA). After detection of physical and chemical characteristics of the nanomaterial, cell toxicity was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Polo-like kinase 1 (PLK1) was investigated as a well-known oncogene, which was a critical regulator of cell cycle transmission at multiple levels. Through knockdown of PLK1 with siRNA carried by novel nanovector, qPCR and Western blot were used to measure the interfering efficiency; apoptosis assay was used to detect the transfection effect of PLK1. All results showed that the novel nanocarrier revealed good biocompatibility, reduced cytotoxicity, as well as high gene-carrying ability without serum interference, thus would have great potential for gene delivery and therapy.

    Full Text Available Current international and national treatment guidelines such as EACS, BHIVA, DHHS or IAS update regularly recommendations on the choice of initial combination antiretroviral treatment (cART regimens. Preferred cART regimens include a backbone with two nucleoside (nucleotide reverse transcriptase inhibitors combined either with one non-nucleoside reverse transcriptase inhibitor or one ritonavir boosted protease inhibitor or more recently one integrase inhibitor. Response rates according to viral load measurements increased in recent years, in particular due to better tolerability. The choice of initial therapy is flexible and influenced by several factors such as height of viral load, genotypic resistance testing, CD4 cell count, co-morbidities, interactions, potential adverse events, (potential for pregnancy, convenience, adherence, costs as well as physician's and patient's preferences. Diverse highly potent initial cART regimens exist. Following the many possibilities, the choice of a regimen is based on a mixture of evidence-informed data and individualized concepts, some of the latter only partly supported by strong evidence. For example, different perceptions and personal experiences exist about boosted protease inhibitors compared to non-nucleoside reverse transcriptase inhibitors or integrase inhibitors and vice versa which may influence the initial choice. This lecture will discuss choices of initial cART in view of international guidelines and the evidence for individualization of initial HIV therapy.

    2015-12-01

    Although several effective therapies are available for the treatment of osteoporosis in postmenopausal women and older men, there remains a need for the development of even more effective and acceptable drugs. Several new drugs that are in late-stage clinical development will be discussed. Abaloparatide (recombinant parathyroid hormone related peptide [PTHrP] analogue) has anabolic activity like teriparatide. Recent data from the phase 3 fracture prevention trial demonstrate that this agent is effective in reducing fracture risk. Inhibiting cathepsin K reduces bone resorption without decreasing the numbers or activity of osteoclasts, thereby preserving or promoting osteoblast function. Progressive increases in bone mineral density (BMD) have been observed over 5 years. Early data suggest that odanacatib effectively reduces fracture risk. Lastly, inhibiting sclerostin with humanized antibodies promotes rapid, substantial but transient increases in bone formation while inhibiting bone resorption. Marked increases in BMD have been observed in phase 2 studies. Fracture prevention studies are underway. The new therapies with novel and unique mechanisms of action may, alone or in combination, provide more effective treatment options for our patients. PMID:26354487

Results: E-therapy is a form of consultation. The author presents publications of researchers who based themselves on cognitive-behavioral therapy, which was effective in the treatment of depressive disorders, anxiety disorders, depressive-anxiety disorders, PTSD, irritable bowel syndrome, bulimia etc. Especially positive outcomes were observed in treatment of anxiety disorders. Results are promising, however the scope of e-therapy use must be carefully defined. Polish ethics code of psychotherapy does not apply to therapeutical contacts via web. We can find directions in American Psychiatric Association advising that despite of the nature of the contact, the same ethical rules should be applied. E-therapy will not replace traditional therapeutical contact but may be considered as an additional method to initiate traditional therapeutical interaction.

    Full Text Available Objectives: Major objective is the evaluation of the medical effectiveness of different therapeutical approaches and the cost effectiveness with relevance for Germany. Methods: This health technology assessment (HTA evaluates systemically randomized controlled studies (RCT on the therapy of atopic dermatitis which were published between 1999 and 2004. Further it includes some important clinical studies which have been published after 2004 and other updates the English HTA report by Hoare et al. [1]. Results: Topical corticosteroids and topical calcineurin-inhibitors are the principal substances which are currently used for anti-inflammatory therapy in atopic dermatitis. These substances have shown a significant therapeutic efficacy in controlled studies. In newer controlled studies no difference was observable when corticosteroids were applied once or more than once daily onto the skin. Moreover, there is now one controlled study available which points to the fact that an interval therapy with a stronger topical corticosteroid over a limited time (some weeks may lower the risk of recurrent flares of atopic dermatitis. Both topical calcineurin-inhibitors pimecrolimus and tacrolimus have shown a significant therapeutical efficacy in a number of placebo-controlled prospective studies. The wealth of data is high for these substances. Both substances have been shown to be efficient in infants, children and adult patients with atopic dermatitis. The importance of a so-called basic therapy with emollients which have to be adapted to the current status of skin is generally accepted in clinical practice. Controlled studies show the efficacy of ”basic therapy” - although the level of evidence is quite low for this approach. The skin of patients with atopic dermatitis is colonized in the majority with Staphylococcus aureus, a gram-positive bacterium. Therefore, a therapeutical approach for the treatment of atopic dermatitis is the anti-bacterial or

    The application of gene transfer technologies to the treatment of cancer has led to the development of new experimental approaches like gene directed enzyme/prodrug therapy (GDEPT), inhibition of oncogenes and restoration of tumor-suppressor genes. In addition,gene therapy has a big impact on other fields like cancer immunotherapy, anti-angiogenic therapy and virotherapy.These strategies are being evaluated for the treatment of primary and metastatic liver cancer and some of them have reached clinical phases. We present a review on the basis and the actual status of gene therapy approaches applied to liver cancer.

    Patients with agammaglobulinaemia and hypogammaglobulinaemia require immunoglobulin G (IgG) replacement therapy to prevent serious infections. Since the 1950s, therapy with human immune globulin products has been the standard of treatment. Currently, the most common routes of administration of IgG replacement therapy are intravenous (IVIG) or subcutaneous (SCIG). The home therapy may improve the quality of life in patients who require lifelong IgG replacement. The -anti-IgA antibody test identifies the patients with the risk of anaphylactoid reactions in IVIG replacement. The SCIG delivery may be used in patients with anti-IgA antibodies and previous systemic reactions to IVIG. PMID:23964967

    Efficient therapies are available for the treatment of osteoporosis, however, there are still unmet needs. Anti-resorptive therapies only increase bone mineral density to a certain extent and reduce the risk of non-vertebral fractures by 20%, only one anabolic option is available-the effect of which levels off over time, and the evidence for combination therapy targeting both resorption and formation is limited. The current review will focus on emerging treatments of osteoporosis with the potential of enhanced anabolic effects (romosozumab and abaloparatide) or uncoupling of resorption and formation (odanacatib and romosozumab) as well as the effect of combination therapy.

    Three related models of therapy are often grouped together as the strategic therapies. These are brief therapy model associated with the Mental Research Institute, approaches developed by Jay Haley and Cloë Madanes, and the model developed by the Milan associates. Controversy exists, however, as to whether the Milan model should be included as a strategic therapy. It appears that the similarities among the three models can mask deeper differences, thus confounding the confusion. This paper contrast the models in their development, theory, and practice.

  12. Iodine neutron capture therapy

    Science.gov (United States)

    Ahmed, Kazi Fariduddin

    A new technique, Iodine Neutron Capture Therapy (INCT) is proposed to treat hyperthyroidism in people. Present thyroid therapies, surgical removal and 131I treatment, result in hypothyroidism and, for 131I, involve protracted treatment times and excessive whole-body radiation doses. The new technique involves using a low energy neutron beam to convert a fraction of the natural iodine stored in the thyroid to radioactive 128I, which has a 24-minute half-life and decays by emitting 2.12-MeV beta particles. The beta particles are absorbed in and damage some thyroid tissue cells and consequently reduce the production and release of thyroid hormones to the blood stream. Treatment times and whole-body radiation doses are thus reduced substantially. This dissertation addresses the first of the several steps needed to obtain medical profession acceptance and regulatory approval to implement this therapy. As with other such programs, initial feasibility is established by performing experiments on suitable small mammals. Laboratory rats were used and their thyroids were exposed to the beta particles coming from small encapsulated amounts of 128I. Masses of 89.0 mg reagent-grade elemental iodine crystals have been activated in the ISU AGN-201 reactor to provide 0.033 mBq of 128I. This activity delivers 0.2 Gy to the thyroid gland of 300-g male rats having fresh thyroid tissue masses of ˜20 mg. Larger iodine masses are used to provide greater doses. The activated iodine is encapsulated to form a thin (0.16 cm 2/mg) patch that is then applied directly to the surgically exposed thyroid of an anesthetized rat. Direct neutron irradiation of a rat's thyroid was not possible due to its small size. Direct in-vivo exposure of the thyroid of the rat to the emitted radiation from 128I is allowed to continue for 2.5 hours (6 half-lives). Pre- and post-exposure blood samples are taken to quantify thyroid hormone levels. The serum T4 concentration is measured by radioimmunoassay at

    What needs to be done on the long road to evidence-based music therapy? First of all, an adequate research strategy is required. For this purpose the general methodology for therapy research should be adopted. Additionally, music therapy needs a variety of methods of allied fields to contribute scientific findings, including mathematics, natural sciences, behavioral and social sciences, as well as the arts. Pluralism seems necessary as well as inevitable. At least two major research problems can be identified, however, that make the path stony: the problem of specificity and the problem of eclecticism. Neuroscientific research in music is giving rise to new ideas, perspectives, and methods; they seem to be promising prospects for a possible contribution to a theoretical and empirical scientific foundation for music therapy. Despite the huge heterogeneity of theoretical approaches in music therapy, an integrative model of working ingredients in music therapy is useful as a starting point for empirical studies in order to question what specifically works in music therapy. For this purpose, a heuristic model, consisting of five music therapy working factors (attention modulation, emotion modulation, cognition modulation, behavior modulation, and communication modulation) has been developed by the Center for Music Therapy Research (Viktor Dulger Institute) in Heidelberg. Evidence shows the effectiveness of music therapy for treating certain diseases, but the question of what it is in music therapy that works remains largely unanswered. The authors conclude with some questions to neuroscientists, which we hope may help elucidate relevant aspects of a possible link between the two disciplines. PMID:16597776

    We studied the efficacy of rheosorbilact, an original infusion drug based on polyalcohols, in the complex therapy of patients with brain ischemia and diabetic neuropathy. Reosorbilact was used intravenously indrops 200-400 ml in day - 20 days. The primary endpoint of the study was the improvement of quality of life assessed with the SF-36 scale after 1 month of treatment. Patients with brain ischemia underwent neuropsychological tests and ultrasound duplex scanning of the carotid and vertebral arteries. In the group of patients with diabetic neuropathy, we evaluated the intensity of pain syndrome with the NRS, blood glucose level and electroneuromyography parameters of low extremities nerves. Some characteristics of acid-base balance were studied in patients of both groups. The results obtained in the study indicate the significant clinical effect of reosorbilact in patients with brain ischemia and diabetic neuropathy. PMID:23994919

It is mainly caused by glaucomatous optic neuropathy (GON characterized by retinal ganglion cell loss, which leads to visual field defect and blindness. Up to now, the main purpose of antiglaucomatous therapies has been to lower intraocular pressure (IOP through surgeries and medications. However, it has been found that progressive GON is still present in some patients with effective IOP decrease. Therefore, risk factors other than IOP elevation, like neurotrophin deprivation and excitotoxicity, contribute to progressive GON.

    Bimatoprost is a neutral lipid, a fatty acid amide that pharmacologically acts in both its paternal amide form and through its hydrolysis product (active free fatty acid of bimatoprost). Hypotensive ocular efficacy of bimatoprost is significantly superior to that of timolol and latanoprost. Mean ocular pressure decreases as well as percentages of reaching and sustaining the low targeting ocular pressures are higher comparing with travoprost. Conjunctival hyperemia produced by bimatoprost is statistically greater than that caused by timolol, latanoprost and travoprost; nevertheless it is well tolerated and mild in severity. Bimatoprost prostamide lowers ocular tension significantly and clinically relevant in patients uncontrolled with latanoprost; that is why bimatoprost can be used as additive or replacement therapy in patients who already receive maximal tolerated dose of latanoprost.

    Perihilar cholangiocarcinoma, which is a rare primary malignancy, originates from the epithelial cells of the bile duct. Usually invading the periductal tissues and the lymph nodes, perihilar cholangiocarcinoma is commonly diagnosed in the advanced stage of the disease and has a dismal prognosis. Currently, complete hepatectomy is the primary therapy for curing this disease. Perioperative assessment and available surgical procedures can be considered for achieving a negative margin resection, which is associated with long-term survival and better quality of life. For patients with unresectable cholangiocarcinoma, several palliative treatments have been demonstrated to produce a better outcome; and liver transplantation for selected patients with perihilar cholangiocarcinoma is promising and desirable. However, the role of palliative treatments and liver transplantation was controversial and requires more evidence and substantial validity from multiple institutions. In this article, we summarize the data from multiple institutions and discuss the resectability, mortality, morbidity and outcome with different approaches.

    Full Text Available Nanotechnology-based advanced materials are rapidly expanding development of better medicines. Long-standing efforts with lipid and polymer colloidal delivery systems, i.e. nanoparticles, have yielded better imaging and therapy. These benefits of nanotechnology, though limited, have driven efforts to develop advanced nanoparticles. This is particularly the case for targeted nucleic acid (gene therapeutics based on short interfering ribonucleic acid (siRNA, which is a new gene inhibitor that is highly potent and selective. Here, we evaluate the use of modular conjugates to construct targeted nanoparticle therapeutics for nucleic acids. These nanoparticles are beginning to emulate the sophistication of virus particles – nature's own nanoscale assemblies for nucleic acids. For medicine, they promise the creation of a new generation of ‘targeted’ therapeutics that can offer multiple levels of selectivity.

    Studies of the structure of particle tracks have led to models of track effects based on radial dose and radiobiological target theory that have been very successful in describing and predicting track effects in physical, chemical, and biological systems. For describing mammalian cellular inactivation two inactivation modes are required, called gamma-kill and ion-kill, the first due to synergistic effects of delta rays from adjacent ion paths thus resembling the effects from gamma rays, and the second to the effects of single ion transits through a cell nucleus. The ion-kill effect is more severe, where the fraction of cells experiencing ion kill is responsible for a decrease in the oxygen enhancement ratio, and an increase in relative biological effectiveness, but these are accompanied by loss of repair, hence to a reduction in the efficiency of fractionation in high LET therapy, as shown by our calculations for radiobiological effects in the "spread out Bragg Peak".

    The rationale and results for interstitial therapies via interventional MRI in the treatment of tumors in various regions are presented. Different interstitial treatment techniques are presented based on varying technologies both for tumor ablation and treatment monitoring. Data are presented based on 335 patients, 29-84 years of age (mean age 59 years, 196 men and 139 women) with a total of 932 liver tumors, 16 head and neck tumors and 14 abdominal recurrent pelvic and lymphatic tumors. All lesions had been treated with MR-guided laser-induced interstitial thermotherapy (LITT) via 2516 laser applications and 1856 cannulations. Data in the literature are extremely varying depending on author experience, treatment technique, and the included patient material. In our patient material we were able to achieve a local tumor control of 96.7 % depending on the size of the tumorous lesion, the topographical relationship, and the applied laser parameters. The overall cumulative survival rate of patients with liver metastases was 45.74 months (median 40.97 months, 95 % confidence interval 31.42-50.52). The cumulative survival rate of the patient group with hepatic metastases of colorectal carcinoma was 42.71 months (median 39.33 months, 95 % confidence interval 33.26-45.37). In patients with head and neck tumors a relevant reduction in clinically relevant symptoms such as pain, swallowing disorders, or nervous compression was achieved in 11 of 15 patients treated with LITT. In 14 soft tissue tumors, such as pelvic tumor recurrence and lymph node metastases, a local tumor control was obtained in 68 % of lesions. Interstitial therapies under interventional MRI guidance, such as LITT, results in a high local tumor control with an improved survival rate. (orig.)

    2012-02-01

    The public and healthcare professionals have become increasingly aware and accepting of the benefit in physical, psychological, social, and spiritual support for patients with cancer. Patients with cancer often seek nonpharmacologic interventions to complement conventional care and decrease the pain associated with cancer and its treatment. Most often referred to as complementary and alternative medicine (CAM), these supportive therapies consist of a heterogeneous group of modalities used as adjuncts to allopathic health care. Biofield therapies are CAM modalities that involve the direction of healing energy through the hands to facilitate well-being by modifying the energy field of the body. This critical review of studies of biofield therapies emphasizes research using these modalities to decrease pain in patients with cancer. Although the therapies have demonstrated clinical efficacy, additional research is warranted. Oncology nurses should familiarize themselves with biofield therapies so they can offer informed recommendations to patients with cancer experiencing pain.

    Radiation therapy using high-energy charged particles is generally acknowledged as a powerful new technique in cancer treatment. However, particle therapy in oncology is still controversial, specifically because it is unclear whether the putative clinical advantages justify the high additional costs. However, particle therapy can find important applications in the management of noncancer diseases, especially in radiosurgery. Extension to other diseases and targets (both cranial and extracranial) may widen the applications of the technique and decrease the cost/benefit ratio of the accelerator facilities. Future challenges in this field include the use of different particles and energies, motion management in particle body radiotherapy and extension to new targets currently treated by catheter ablation (atrial fibrillation and renal denervation) or stereotactic radiation therapy (trigeminal neuralgia, epilepsy, and macular degeneration). Particle body radiosurgery could be a future key application of accelerator-based particle therapy facilities in 10 years from today.

    2012-02-01

    The public and healthcare professionals have become increasingly aware and accepting of the benefit in physical, psychological, social, and spiritual support for patients with cancer. Patients with cancer often seek nonpharmacologic interventions to complement conventional care and decrease the pain associated with cancer and its treatment. Most often referred to as complementary and alternative medicine (CAM), these supportive therapies consist of a heterogeneous group of modalities used as adjuncts to allopathic health care. Biofield therapies are CAM modalities that involve the direction of healing energy through the hands to facilitate well-being by modifying the energy field of the body. This critical review of studies of biofield therapies emphasizes research using these modalities to decrease pain in patients with cancer. Although the therapies have demonstrated clinical efficacy, additional research is warranted. Oncology nurses should familiarize themselves with biofield therapies so they can offer informed recommendations to patients with cancer experiencing pain. PMID:22297006

    Cancer has been, from the beginning, a target of intense research for gene therapy approaches. Currently, more than 60% of all on-going clinical gene therapy trials worldwide are targeting cancer. Indeed, there is a clear unmet medical need for novel therapies. This is further urged by the fact that current conventional cancer therapies are frequently troubled by their toxicities. Different gene therapy strategies have been employed for cancer, such as pro-drug activating suicide gene therapy...

    2012-11-01

    Oncolytic virus (OV) therapy currently represents one of the most promising approaches to cancer treatment for their dual anticancer mechanisms: direct lysis of cancer cells (oncolytic feature) and activation of the immunosystem (cancer vaccine aspect). The latter demonstrates the advantage of a multi-target approach against multiple tumor-associated antigens. Since the 2005 SFDA (the Chinese FDA) approval for the clinical use of Oncorine™, the first human OV-based cancer treatment, more than 200 patents have been filed worldwide and several Phase I/II studies have been conducted. This patent review analyzes patents and clinical studies of the most promising OV products to highlight the pros and cons of this innovative anticancer approach, which is currently being tested in several cancers (i.e., hepatocellular carcinoma, melanoma and glioblastoma) by systemic as well as intratumoral injection. Clinical results, although effective only for a limited period of time, are encouraging. Combined treatments with radio or chemotherapeutic protocols are also in progress. PMID:24236929

    Full Text Available The analysis of the disease from a spiritual perspective means to take into account those theories that do not consider the patient as part of some statistics or the disease as an exclusive psycho-somatic reality, which is due to disturbances of the physiological system. To consider the person exclusively from the stand point of the disease leads to a situation in which the diagnosis creates the patient. To asses that any condition of this nature can be cured or improved solely through medication – as there is pressure from the U.S. health insurance companies – has an effect of shrinking responsibility of the patient who is not involved in the healing process. Fortunately, in the twentieth century, a number of therapies that regard the patient as the central concern, have been developed- obviously, not regarding the chronically ill, which remain the patient of the psychiatric cure- as a person responsible for what happens to him/her, of affection, and the amelioration of his/her health. Of these, in our article we reviewed the principles of existential psychotherapy by Irvin D. Yalom, Viktor Frenkl’s logotherapy and the humanistic psychotherapy (customer centric by Carl R. Rogers.

  9. Principles of radiation therapy

    International Nuclear Information System (INIS)

    Radiation oncology now represents the integration of knowledge obtained over an 80-year period from the physics and biology laboratories and the medical clinic. Such integration is recent; until the supervoltage era following World War II, the chief developments in these three areas for the most part were realized independently. The physics and engineering laboratories have now developed a dependable family of sources of ionizing radiations that can be precisely directed at tumor volumes at various depths within the body. The biology laboratory has provided the basic scientific support underlying the intensive clinical experience and currently is suggesting ways of using ionizing radiations more effectively, such as modified fractionation schedules relating to cell cycle kinetics and the use of drugs and chemicals as modifiers of radiation response and normal tissue reaction. The radiation therapy clinic has provided the patient stratum on which the acute and chronic effects of irradiation have been assessed, and the patterns of treatment success and failure identified. The radiation therapist has shared with the surgeon and medical oncologist the responsibility for clarifying the natural history of a large number of human neoplasms, and through such clarifications, has developed more effective treatment strategies. Several examples of this include the improved results in the treatment of Hodgkin's disease, squamous cell carcinoma of the cervix, seminoma, and epithelial neoplasms of the upper aerodigestive tract

    Patients with AJCC Stage IIB and III melanoma have a poor 5-year survival rate which has been the driving force behind attempts to find an effective adjuvant therapy for this stage of disease that would effectively reduce relapse and improve survival. Immunotherapy with bacillus Calmette-Guerin (BCG), Corynebacterium parvum, and levamisole have not been successful in achieving this goal, nor have trials with chemotherapy in the adjuvant setting, including high-dose chemotherapy with autologous bone marrow transplantation. The recent Eastern Cooperative Oncology Group (ECOG) 1684 study showed significant improvement in relapse-free and overall survival with high doses of alpha interferon (IFNalpha) given for 1 year. Lower dosages of IFNalpha have to date been unsuccessful in impacting upon long-term survival. Recent data with vaccines have been encouraging, and the GM2-KLH vaccine is the focus of ongoing intergroup study comparing this treatment with IFNalpha in resected Stage IIB and III melanoma. The various regimens are reviewed in this article. PMID:9588723

  11. Radionuclide Therapy. Chapter 19

    International Nuclear Information System (INIS)

    Cancer has been treated with radiopharmaceuticals since the 1940s. The radionuclides originally used, including 131I and 32P, are still in use. The role of the physicist in radionuclide therapy encompasses radiation protection, imaging and dosimetry. Radiation protection is of particular importance given the high activities of the unsealed sources that are often administered, and must take into account medical staff, comforters and carers, and, as patients are discharged while still retaining activity, members of the public. Regulations concerning acceptable levels of exposure vary from country to country. If the administered radiopharmaceutical is a γ emitter, then imaging can be performed which may be either qualitative or quantitative. While a regular system of quality control must be in place to prevent misinterpretation of image data, qualitative imaging does not usually rely on the image corrections necessary to determine the absolute levels of activity that are localized in the patient. Accurate quantitative imaging is dependent on these corrections and can permit the distribution of absorbed doses delivered to the patient to be determined with sufficient accuracy to be clinically beneficial

    2012-10-01

    Ultrasound provides key benefits in aesthetic surgery compared to laser and RF based energy sources. We present results of research, development, pre-clinical and clinical studies, regulatory clearance and commercialization of a revolutionary non-invasive aesthetic ultrasound imaging and therapy system. Clinical applications for this platform include non-invasive face-lifts, brow-lifts, and neck-lifts achieved through fractionated treatment of the superficial musculoaponeurotic system (SMAS) and subcutaneous tissue. Treatment consists of placing a grid of micro-coagulative lesions on the order of 1 mm3 at depths in skin of 1 to 6 mm, source energy levels of 0.1 to 3 J, and spacing on the order of 1.5 mm, from 4 to 10 MHz dual-mode image/treat transducers. System details are described, as well as a regulatory pathway consisting of acoustic and bioheat simulations, source characterization (hydrophone, radiation force, and Schlieren), pre-clinical studies (porcine skin ex vivo, in vivo, and human cadaver), human safety studies (treat and resect) and efficacy trials which culminated in FDA clearance (2009) under a new device classification and world-wide usage. Clinical before and after photographs are presented which validate the clinical approach.

  13. Dietary Therapies for Epilepsy

    Full Text Available Since their introduction in 1921, high-fat, low-carbohydrate "ketogenic" diets have been used worldwide for refractory childhood epilepsy. Approximately half of the children have at least half their seizures reduced, including 15% who are seizure free. The mechanisms of action of dietary therapies are under active investigation and appear to involve mitochondria. Once perceived as a last resort, modifications to initiation and maintenance, as well as the widespread use of pre-made ketogenic formulas have allowed dietary treatment to be used earlier in the course of epilepsy. For infantile spasms (West syndrome specifically, the ketogenic diet is successful about 50% of the time as a first-line treatment. New "alternative" diets such as the modified Atkins diet were created in 2003 and can be started more easily and are less restrictive. They may have particular value for countries in Asia. Side effects include constipation, dyslipidemia, growth slowing, acidosis, and kidney stones. Additionally, neurologists are studying ketogenic diets for conditions other than epilepsy, including Alzheimer's disease, autism, and brain tumors.

  14. Therapie des abdominellen Aortenaneurysmas

    Directory of Open Access Journals (Sweden)

    Rieß HC

    2014-01-01

    Full Text Available Zur invasiven elektiven und notfallmäßigen Therapie des abdominellen Aortenaneurysmas steht vor allem das offen-chirurgische und das endovaskuläre Verfahren zur Verfügung. Aufgrund einer deutlich erhöhten Mortalitätsrate im rupturierten Stadium sollte dabei stets ein elektives Vorgehen angestrebt werden. Die rechtzeitige Identifizierung erkrankter Patienten im asymptomatischen Stadium, beispielsweise im Rahmen eines Aortenscreenings für Risikogruppen, ist aus diesem Grund von größter Wichtigkeit. Trotz mehrerer randomisierter Studien zu den genannten Therapieoptionen kann bis heute keine vereinfachende Therapieempfehlung für eines der beiden konkurrierenden Verfahren ausgesprochen werden. Die Indikationsstellung erfordert stets eine sehr differenzierte Berücksichtigung aller eingehenden Faktoren. Auch ohne eine klare Empfehlung hat die endovaskuläre Versorgung des Aortenaneurysmas in vielen Ländern, so auch in Deutschland, bereits einen Anteil von über 50 % erlangt. Die kontinuierliche Verbesserung von Verfahren und Material spiegelt sich in einer signifikant kürzeren Krankenhausverweildauer und in einer niedrigeren Letalität der EVAR bei hohen technischen Erfolgsraten wider. Im Hinblick auf Langzeitergebnisse profitieren heute überwiegend ältere Personen von einer endovaskulären Aneurysma-Ausschaltung, für die aufgrund eines hohen OP-Risikos eine offen-chirurgische Versorgung nicht in Frage kommt. Zukünftig werden, bei einem vergleichbaren Outcome beider Verfahren, auch gesundheitsökonomische Aspekte eine Rolle spielen und in die Empfehlungen eingehen.

  15. [Dignity therapy in oncology].

    Ripamonti, Carla Ida

    2016-04-01

    In oncology, little is known about dignity, dignity-related distress and the issues that influence the sense of dignity for patients. Dignity is personal, subject to changes depending on the experience and the path of life. In oncology some patients feel that their dignity is directly related to the disease, to physical and emotional symptoms, to the highest level of physical and cognitive autonomy and to the continuity of the self. Patient dignity inventory (PDI) is a validate tool designed to measure various sources of dignity-related distress among patients nearing the end of life and serve as a screening tool to assess a broad range of issues that influence the sense of dignity. Dignity therapy is a novel focused psychotherapy consisting in a brief semi-structured interview, audio-recorded and transcribed in order to obtain the "generativity document". The patients are invited to tell about their life history, and to leave words of guidance and offer instructions to pass along to their son, daughters, husband, wife, parents, others. The generativity document is the result of process of emotional and existential care for the patients and a gift for everybody will receive it. PMID:27093325

    2014-01-01

    Summary Background Liver abscess (LA) is an uncommon but potentially life-threatening disease with significant morbidity and mortality. Methods This review comprehensively describes epidemiology, pathogenesis, diagnosis, and treatment of LA, with a strong focus on antimicrobial treatment choices and the impact of multidrug-resistant pathogens. Results In industrialized areas, pyogenic liver abscess (PLA) accounts for over 80% of the cases, whereas Entamoeba histolyticais responsible for up to 10% of the cases, with a higher incidence in tropical areas. Highly virulent strains of Klebsiella pneumoniaehave emerged as a predominant cause of PLA in Asian countries and tend to spread to the USA, Australia, and European countries, therefore requiring special alertness. Most common symptoms of LA are fever, chills, and right upper quadrant abdominal pain, although a broad spectrum of non-specific symptoms may also occur. Conclusion Imaging studies (ultrasound, computed tomography scan) and microbiological findings play a crucial role in the diagnosis of LA. The treatment of choice for PLA is a multimodal approach combining broad-spectrum antibiotics and aspiration or drainage of larger abscess cavities. Amebic LA can be cured by metronidazole therapy without drainage. PMID:26287275

    HIV/AIDS has been an extremely difficult pandemic to control. However, with the advent of antiretroviral therapy (ART), HIV has now been transformed into a chronic illness in patients who have continued treatment access and excellent long-term adherence. Existing indications for ART initiation in asymptomatic patients were based on CD4 levels; however, recent evidence has broken the shackles of CD4 levels. Early initiation of ART in HIV patients irrespective of CD4 counts can have profound positive impact on morbidity and mortality. Early initiation of ART has been found not only beneficial for patients but also to community as it reduces the risk of transmission. There have been few financial concerns about providing ART to all HIV-positive people but various studies have proven that early initiation of ART not only proves to be cost-effective but also contributes to economic and social growth of community. A novel multidisciplinary approach with early initiation and availability of ART at its heart can turn the tide in our favor in future. Effective preexposure prophylaxis and postexposure prophylaxis can also lower transmission risk of HIV in community. New understanding of HIV pathogenesis is opening new vistas to cure and prevention. Various promising candidate vaccines and drugs are undergoing aggressive clinical trials, raising optimism for an ever-elusive cure for HIV. This review describes various facets of tectonic shift in management of HIV. PMID:26900224

  18. Neutron capture therapy

    International Nuclear Information System (INIS)

    The overall state of the art related with neutron capture therapy(NCT) is surveyed. Since the field related with NCT is very wide, it is not intended to survey all related subjects in depth. The primary objective of this report is to help those working for the installation of a NCT facility and a PGNAA(prompt gamma ray neutron activation analysis) system for the boron analysis understand overall NCT at Hanaro. Therefore, while the parts of reactor neutron source and PGNAA are dealt in detail, other parts are limited to the level necessary to understand related fields. For example, the subject of chemical compound which requires intensive knowledge on chemistry, is not dealt as a separated item. However, the requirement of a compound for NCT, currently available compounds, their characteristics, etc. could be understood through this report. Although the subject of cancer treated by NCT is out of the capability of the author, it is dealt focussing its characteristics related with the success of NCT. Each detailed subject is expected to be dealt more detail by specialists in future. This report would be helpful for the researchers working for the NCT to understand related fields.

  19. Therapy of pancreatic cancer

    International Nuclear Information System (INIS)

    Pancreatic cancer remains one of the most difficult diseases to cure. Japan pancreas society guidelines for management of pancreatic cancer indicate therapeutic algorithm according to the clinical stage. For locally limited pancreatic cancer (cStage I, II, III in Japanese classification system), surgical resection is recommended, however prognosis is still poor. Major randomized controlled trials of resected pancreatic cancer indicates that adjuvant chemotherapy is superior to observation and gemcitabine is superior to 5-fluorouracil (FU). For locally advanced resectable pancreatic cancer (cStage IVa in Japanese classification system (JCS)), we perform neoadjuvant chemoradiotherapy. Phase I study established a recommended dose of 800 mg gemcitabine and radiation dose of 36 Gy. For locally advanced nonresectable pancreatic cancer (cStage IVa in JCS), chemoradiotherapy followed by chemotherapy is recommended. Although pancreatic cancer is chemotherapy resistant tumor, systemic chemotherapy is recommended for metastatic pancreatic cancer (cStage IVb in JCS). Single-agent gemcitabine is the standard first line agent for the treatment of advanced pancreatic cancer. Meta-analysis of chemotherapy showed possibility of survival benefit of gemcitabine combination chemotherapy over gemcitabine alone. We hope gemcitabine combination chemotherapy or molecular targeted therapy will improve prognosis of pancreatic cancer in the future. (author)

  20. Meson radiobiology and therapy

    International Nuclear Information System (INIS)

    High-linear energy transfer radiation (neutrons, heavy ions, and pions) have a greater relative biological effectiveness than low-linear energy transfer radiation by depositing a high density of ionization in irradiated cells. This overcomes the protective effect of oxygen; decreases the variation in sensitivity among the several stages of the cell cycles; and, inhibits the repair of sublethal damage as compared to x-rays, gamma rays, electrons and protons. Negative pi mesons (pions), appear particularly suited for radiation therapy as their penetration and depth-dose profiles lend themselves to shaping the high dose area to the tumor size and location. Preliminary biological experiments with pions produced at the Los Alamos Meson Physics Facility studied cell survival at various radiation depths and cell cycle sensitivity. Histologic study of data from the first human experiments indicated severe tumor cell destruction by pions as compared to x-rays in treating malignant melanoma skin nodules, without increased effects on dermal elements.
