Breast cancer is the most common cancer in women worldwide and the solid tumor type for which the highest number of drugs have been approved to date. This study examines new drug approvals for breast cancer by the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA), based on an analysis of regulatory documents from both agencies for the period from 1995 to 2018. Of the 29 breast cancer drugs approved over this time span, 17 received positive decisions from both the FDA and EMA, including all drugs licensed after 2008. Nineteen of the 25 FDA-approved drugs, but none of the EMA approvals, benefited from special regulatory pathways (such as fast track, breakthrough therapy, or priority review). In the U.S.A., four accelerated approvals were granted (of which one, for bevacizumab, was later revoked), while only two drugs received provisional approvals following EMA review. New breast cancer drugs were approved approximately twelve months earlier in the United States than in Europe. These results suggest that a broader use of special regulatory pathways by EMA could help to accelerate access to novel drugs for European breast cancer patients.

Background: The increasing consumption of dietary supplements (DS) has drawn the attention of regulatory agencies, researchers and healthcare professionals. The US Food and Drug Administration (FDA) does not require premarketing assessment of DS considering them safe unless proven otherwise. However, the reporting rate of DS adverse events (DS-AE) is low. Objective: To describe pharmacists’ attitudes and knowledge of DS and DS information resources, and to determine the importance of selected attributes in pharmacists’ decisions to report a DS-AE. Methods: A convenience sample of practicing pharmacists in Virginia was surveyed using a web-based self-administered questionnaire. A conjoint analysis exercise was developed using several scenarios based on a set of five attributes: patient’s age, initiation of DS, last modification in drug therapy, evidence supporting the AE, and outcome of the AE. Participants were asked to indicate their decision to report the AE in each scenario to prescriber, drug manufacturer, DS manufacturer and FDA on a 6-point ordered scale. Participants’ attitude, knowledge of DS, demographic information, and DS information resources were also requested. Linear regression models were used to determine the relative importance of the profile attributes on a pharmacist’s decision to report the AE. The effects of other characteristics on the importance of the attributes were assessed. Results: Participants’ overall attitudes were relatively positive for the clinical use of DS but negative for safe of DS. Formal training on DS was associated with better knowledge of DS regulation. The average knowledge score of DS identification was relatively good but was low for DS regulation. Lexi-Comp® was the most widely used and available information resource and the Natural Medicines Comprehensive Database was the most useful once. The most important attribute that a pharmacist considered in the decision to report a DS-AE to DS manufacturer, drug manufacturer and FDA was the outcome of the AE followed by the evidence supporting the AE. Ranking of these two factors was the reversed in reporting to prescriber. Conclusions: Outcome and evidence of the AE are the most important factors participants considered when reporting. Other characteristics do not have an impact on the relative importance of the attributes.

Hipodermóclise (HDC) é uma importante técnica alternativa para a administração de medicamentos e fluidos pela via subcutânea. É usada com frequência para o controle dos sintomas em pacientes em cuidados paliativos com dificuldade de acesso venoso e que são incapazes de tolerar medicação oral. No entanto, raros estudos abordaram o uso da HDC de uma forma global, para reposição hidroeletrolítica e terapia medicamentosa, tanto na forma contínua quanto intermitente, observando detalhes e complicações do seu uso. Os objetivos deste estudo incluíram caracterizar o uso da HDC para administração de medicamentos, soluções e eletrólitos e avaliar as possíveis complicações locais, identificando também outros fatores que influenciam sua ocorrência. Estudo observacional prospectivo com coleta de dados em prontuário e acompanhamento diário de pacientes internados com câncer avançado, da equipe de Cuidados Paliativos do Instituto do Câncer do Estado de São Paulo (ICESP) em uso de HDC, verificando local de punção, medicamentos administrados e possíveis complicações, acompanhando os detalhes de seu uso. A análise estatística não-paramétrica e método de regressão logística foram realizados. Foram acompanhados 99 pacientes com 243 punções, das quais 166 (68,3%) em coxa e 46 (18,9%) em abdome. Os medicamentos mais utilizados foram morfina em 122 (50,2%) punções, seguido de dipirona em 118 (48,6%) e dexametasona em 86 (35,4%). A solução mais prescrita foi a glicofisiológica em 38 (15,6%) punções, pelo seu aporte calórico. 13,6% das punções (33 de 243) tiveram complicações, sendo apenas seis casos maiores (edema). Complicações ocorreram mais frequentemente até o segundo dia da punção e foram associadas com o número (p=0,007) e o volume (p=0,042) de medicamentos administrados e também com a solução glicofisiológica (p=0,003) e os eletrólitos cloreto de potássio (p=0,037) e cloreto de sódio (p=0,013). Este estudo permitiu o conhecimento de fatores associados a complicações e propõe algumas recomendações, como: individualização da terapia, especialmente relacionada com o volume de escolha, número de medicamentos administrados e evitar a adição de eletrólitos na solução glicofisiológica / Hypodermoclysis (HDC) is an important alternative technique for the administration of drugs and fluids into the subcutaneous tissue. It is frequently used for symptom control in palliative care patients, with difficult venous access and unable to tolerate oral medications. However, few studies address the use of HDC as a whole to fluid replacement and drug therapy, both continuous and intermittent mode, observing details and complications of its use. The objectives of this study included characterizing the use of HDC to administer drugs, solutions and electrolytes and to evaluate possible local complications also identifying other factors influencing their occurrence. Prospective observational study with data collection in medical records and daily monitoring of advanced cancer inpatients of the palliative care team of São Paulo State Cancer Institute (ICESP) in use of HDC, checking infusion site, administered drugs and possible complications, following the details of its use. Non-parametrical statistical analysis and logistic regression were performed. Were followed 99 patients with 243 infusion sites, which 166 (68.3%) in the thigh and 46 (18.9%) in the abdomen. The most commonly used drugs were morphine in 122 (50.2%) infusion sites, followed by dipyrone in 118 (48.6%) and dexamethasone in 86 (35.4%). The most prescribed solution was dextrose 5%/0,9% saline in 38 (15.6%) infusion sites because of its caloric intake. 13.6% of punctures (33 of 243) had complications, only six larger cases (edema). Complications occurred mainly up to the second day of the infusion sites and were associated with the number (p=0,007) and volume (p=0,042) of drugs used as also with 5% dextrose/0.9% saline solution (p=0,003) and NaCl (p=0,037) and KCl (p=0,013) electrolytes. This study has allowed the knowledge of factors associated with complications and proposes some recommendations as: individualization of therapy especially related to the volume of choice, number of drugs administered, and avoid adding electrolytes to the 5% dextrose/0.9% saline solution

OBJECTIVE: Complaints of cognitive changes are often expressed by patients at all stages of HIV infection. Such changes include decreased memory and attention span, diminished concentration, apathy, and "slowing." Methylphenidate (MPD) has been used in several clinical studies in men with late-stage HIV disease in an attempt to ameliorate these difficulties. The objectives of this review article are to review salient psychopharmacological characteristics of MPD and to describe the research and clinical literature supporting the use of MPD in patients at all stages of HIV infection. METHODS: Seven studies, case reports, or abstracts from International Conferences on AIDS were available in the English literature through August, 1993, directly addressing the use of MPD in patients with HIV disease. Twenty-nine papers were reviewed for pharmacokinetic data, eighteen for safety and side effects issues, and seventeen for relevant contributions from the neuropsychological testing literature. RESULTS: Studies in clinical settings have used doses ranges from 10-90 mg. per day in two or three divided doses with reportedly good results in improving both affective and cognitive symptoms associated with HIV disease. Side effects have been relatively mild and patient satisfaction with treatment has been high. However, no studies have been conducted in early stage HIV disease, where a significant minority of patients have similar complaints in the absence of clinically apparent immunosuppression. Likewise, placebo-controlled, dose-finding studies in AIDS patients are entirely lacking, and no studies in women with HIV disease and cognitive changes have been published. CONCLUSIONS: In spite of these important research short-comings, clinical experience with MPD treatment of cognitive changes in men with HIV/AIDS is consistent with the notion that this medication holds significant promise to improve the quality of life for persons living with HIV/AIDS. Controlled studies to test this hypothesis are warranted.

The Master’s thesis deals with the area of conducting process audits in a large multinational corporation focused on manufacturing and distribution of medical devices, which has a subsidiary in the Czech Republic. The thesis discusses the analysis of the current set up of the internal audits‘ system in the corporation and there are changes of the quality system being proposed on the basis of the analysis, whose aim is to achieve a full compliance with the requirements of the US administration FDA, the standard ISO 13485 as well as the recent requirements on performing process audits. The emphasis is also put on the setting of the system such that it provides the highest possible added value for its users, can be easily implemented in practice and is flexible as well.

In the undertaking a recent history of such a fundamental law as one that deals with food, drugs and cosmetics in its relationship to the human race, we should realize that such a field has a history possibly as old as man himself. There have always been individuals in the good and welfare of others, and there have always been individuals interested in taking advantage of their fellow man for personal gain, frequently in an exceedingly unscrupulous manner. The Solicitor General of the United States, in a recent paper read at the commemoration the the fortieth anniversary of the original Federal Food and Drugs Act of 1906 pointed out that "the attempts of organized society to prevent the adulteration of food and drugs date back to ancient times. The racket implicit in the purveying of adulterated and misbranded commodities is now a new one by any means -- it has been practiced from the commencement of recorded times." The officials goes on and recites specific instances, telling how Pliny the Elder complained of "white earth" in his bread, the pepperers and spicers of London in the year 1316 began to regulate the quality of their produce, brewers were subject to fines for adulterating beer in the days of William the Conqueror, food control statutes were passed in France and Germany in the thirteenth century. The first pharmacopoeia was published in England by the College of physicians in 1613. In the fourteenth century the Provost of Paris forade the artificial coloring of butter. In the United States, Congress enacted a law to prevent the importation of adulterated and spurious drugs and medicine as far back as 1846. The Department of Agriculture through its Division (later Bureau) of Chemistry from 1863 to 1906 in its reports kept calling to the attention of the various Secretaries of Agriculture, and in a measure to the attention of Congress and the people of the United States, the need for remedying conditions of food and drug frauds perpetrated upon the consumer.

Background Iron deficiency (ID) is the world‟s most prevalent micronutrient deficiency and predominantly affects developing countries, also South Africa. In areas with low fish consumption and high n-6 PUFA vegetable oil intake, there is a risk for having inadequate n-3 PUFA status. Both iron and n-3 PUFA play important roles in the immune response, and supplementation is a strategy to alleviate deficiencies. However, little is known about potential interactive effects between concurrent iron and n-3 PUFA supplementation on the immune system. This is also important in the context that iron supplementation may be unsafe and may increase morbidity and mortality. Aim The overall aim of this thesis was to assess the effects of iron and docosahexaenoic (DHA)/eicosapentaenoic acid (EPA) supplementation, alone and in combination, on the immune system of ID children. More specifically, these effects were investigated on the occurrence and duration of illness and school-absenteeism due to illness, peripheral blood mononuclear cell (PBMC), red blood cell (RBC) and plasma total phospholipid fatty acid composition, iron status, fatty acid-derived immune modulators and targeted PBMC gene expression. Furthermore, association of PBMC, RBC and plasma total phospholipid fatty acid composition with allergic disease, were also examined. Design In a 2-by-2 factorial, randomised, double-blind, placebo-controlled trial, South African children (n = 321, aged 6–11 y) were randomly assigned to receive oral supplements of either 1) iron (50 mg as ferrous sulphate) plus placebo; 2) DHA/EPA (420/80 mg) plus placebo; 3) iron plus DHA/EPA (420/80 mg); or 4) placebo plus placebo for 8.5 mo, four times per week. Absenteeism and illness symptoms were recorded and biochemical parameters for compliance as well as parameters fundamental to immune function were assessed at baseline and endpoint. Furthermore, in a cross-sectional design, associations of allergic disease with baseline fatty acid composition of PBMC, RBC and plasma were examined. Results The combination of iron and DHA/EPA significantly attenuated respiratory illness caused by iron supplementation. DHA/EPA supplementation alone improved respiratory symptoms at school, but increased headache-related absenteeism. DHA/EPA and iron supplementation individually tended to increase and decrease anti-inflammatory DHA and EPA-derived mediators, respectively. Furthermore the anti-inflammatory DHA-derived immune mediator, 17HDHA was higher in the DHA/EPA plus placebo and iron plus DHA/EPA groups than in the iron plus placebo group. Also, the pro-inflammatory arachidonic acid (AA)-derived modulators (5- and 15-hydroxyeicosapentaenoic acid) were significantly lower in the iron plus DHA/EPA group compared to the placebo plus placebo groups. In the study population, 27.2% of the children had allergic disease and AA in PBMC phospholipids was significantly lower in the allergic children than in the non-allergic children. In RBC phospholipids dihomo-gamma-linolenic acid (DGLA) and the ratio of DGLA: linoleic acid (LA) correlated negatively and the n-6:n-3 PUFA ratio positively with total immunoglobulin E (tIgE). Furthermore, trans-C18:1n-9, tended to be higher in the allergic group. Conclusion DHA/EPA prevented respiratory illness caused by iron supplementation and although DHA/EPA on its own reduced respiratory morbidity when the children were present at school, surprisingly it increased the likelihood of being absent with headache and fever. The biochemical findings compliment the clinical results and support previous observations about DHA/EPA supplementation to reduce inflammation, but add to the current knowledge base that a relatively high oral dose of non-haem iron modulates circulating lipid-derived immune modulators and related gene expression. Furthermore, when supplementing with iron and DHA/EPA combined, in this ID population with low fish intake, the anti-inflammatory effect of DHA/EPA is maintained concurrently with attenuation of respiratory morbidity. This finding support the notion that excess iron (probably as non-transferrin bound iron) becomes available for pathogens and is probably why we found that iron increased respiratory infectious morbidity. The improved clinical outcome with combined supplementation seems to be related to increased lipid-mediator synthesis gene expression and the availability of DHA/EPA, leading to a more pro-resolving profile and enhanced immune competence. Overall these results give better insight into immune function and infectious morbidity in relation to n-3 PUFA and iron status and treatment, as well as the possible association of fatty acid status with allergic disease in young South-African school children. / PhD (Nutrition), North-West University, Potchefstroom Campus, 2015
