Developing an efficient and reliable dry powder inhaler for pulmonary drug delivery : a review for multidisciplinary researchers

Pulmonary drug delivery is the focus of much research and development because of its great potential to produce maximum therapeutic benefit. Among the available options the dry powder inhaler (DPI) is the preferred device for the treatment of an increasingly diverse number of diseases. However, as drug delivery from a DPI involves a complicated set of physical processes and the integration of drug formulations, device design and patient usage, the engineering development of this medical technology is proving to be a great challenge. Currently there is large range of devices that are either available on the market or under development, however, none exhibit superior clinical efficacy. A major concern is the inter- and intra-patient variability of the drug dosage delivered to the deep lungs. The extent of variability depends on the drug formulation, the device design and the patient’s inhalation profile. This article reviews recent advances in DPI technology and presents the key factors which motivate and constrain the successful engineering of a universal, patient-independent DPI that is capable of efficient, reliable and repeatable drug delivery. A strong emphasis is placed on the physical processes of drug powder aerosolisation, deagglomeration, and dispersion and on the engineering of formulations and inhalers that can optimise these processes.

Studies on the pathophysiology and genetic basis of migraine

Migraine is a neurological disorder that affects the central nervous system causing painful attacks of headache. A genetic vulnerability and exposure to environmental triggers can influence the migraine phenotype. Migraine interferes in many facets of people’s daily life including employment commitments and their ability to look after their families resulting in a reduced quality of life. Identification of the biological processes that underlie this relatively common affliction has been difficult because migraine does not have any clearly identifiable pathology or structural lesion detectable by current medical technology. Theories to explain the symptoms of migraine have focused on the physiological mechanisms involved in the various phases of headache and include the vascular and neurogenic theories. In relation to migraine pathophysiology the trigeminovascular system and cortical spreading depression have also been implicated with supporting evidence from imaging studies and animal models. The objective of current research is to better understand the pathways and mechanisms involved in causing pain and headache to be able to target interventions. The genetic component of migraine has been teased apart using linkage studies and both candidate gene and genome-wide association studies, in family and case-control cohorts. Genomic regions that increase individual risk to migraine have been identified in neurological, vascular and hormonal pathways. This review discusses knowledge of the pathophysiology and genetic basis of migraine with the latest scientific evidence from genetic studies.

Cytotoxic Effects and Biocompatibility of Antimicrobial Materials

The rising demand for medical implants for ageing populations and ongoing advancements in medical technology continue to drive the use of implantable devices. Higher implant usage has a consequent increased incidence of implant-related infections, and associated prolonged patient care, pain and loss of limb and other organ function. Numerous antibacterial surfaces have been designed that prevent the onset of biofilm formation, thus reducing or preventing implant-associated infections through inhibiting bacterial adhesion or by killing the organisms that successfully attach to the surface of the implant. Other surfaces have been designed to stimulate a local immune response, promoting the natural clearing of the invading pathogen. The desired antibacterial effects are typically achieved by modulating the surface chemistry and morphology of the implant material, by means of the controlled release of pharmacological agents and bioactive compounds from the surface of the material, or by a combination of both processes. An important issue for any type of antibacterial surface modification lies in balancing the non-fouling, bacteriostatic or bactericidal effects against local and systemic biocompatibility. In this chapter, we will first describe the concept of biocompatibility and its evolution, from devices that do not evoke a negative host response to those that actively drive host regeneration. We will then review the challenges associated with merging the need for an implant material to withstand a bacterial load with those associated with supporting function restoration and tissue healing.

Temperature monitoring of nonanaesthetised patients in a cardiac catheterisation laboratory

Aim and objectives To identify the prevalence that temperature reduced by more than 1°C from pre to post-procedure in a sample of non-anaesthetised patients undergoing procedures in a cardiac catheterisation laboratory. Background Advances in medical technology are minimising the invasiveness of diagnostic tests and treatments for disease, which is correspondingly increasing the number of medical procedures performed without sedation or anaesthesia. Procedural areas in which medical procedures are performed without anaesthesia are typically kept at a cool temperature for staff comfort. As such, there is a need to inform nursing practices in regard to the thermal management of non-anaesthetised patients undergoing procedures in surgical or procedural environments. Design Single-site observational study Methods Patients were included if they had undergone an elective procedure without sedation or anaesthesia in a cardiac catheterisation laboratory. Ambient room temperature was maintained between 18°C and 20°C. Passive warming with heated cotton blankets was applied. Nurses measured body temperature and thermal comfort before and after 342 procedures. Results Mean change in temperature was -0.08°C (Standard deviation 0.43). The reduction in temperature was more than 1°C after 11 procedures (3.2%). One patient whose temperature had reduced more than 1°C after their procedure reported thermal discomfort. A total of 12 patients were observed to be shivering post-procedure (3.6%). No demographic or clinical characteristics were associated with reduction in temperature of more than 1°C from pre to post-procedure. Conclusions Significant reduction in body temperature was rare in our sample of non-anaesthetised patients. Relevance to clinical practice Similar results would likely be found in other procedural contexts during procedures conducted in settings with comparable room temperatures where passive warming can also be applied with limited skin exposure.

Elämän tiede : Tutkimus lääketieteellisestä teknologiasta, vanhemmuudesta ja perimän hallinnasta

Doctoral dissertation work in sociology examines how human heredity became a scientific, political and a personal issue in the 20th century Finland. The study focuses on the institutionalisation of rationales and technologies concerning heredity, in the context of Finnish medicine and health care. The analysis concentrates specifically on the introduction and development of prenatal screening within maternity care. The data comprises of medical articles, policy documents and committee reports, as well as popular guidebooks and health magazines. The study commences with an analysis on the early 20th century discussions on racial hygiene. It ends with an analysis on the choices given to pregnant mothers and families at present. Freedom to choose, considered by geneticists and many others as a guarantee of the ethicality of medical applications, is presented in this study as a historically, politically and scientifically constructed issue. New medical testing methods have generated new possibilities of governing life itself. However, they have also created new ethical problems. Leaning on recent historical data, the study illustrates how medical risk rationales on heredity have been asserted by the medical profession into Finnish health care. It also depicts medical professions ambivalence between maintaining the patients autonomy and utilizing for example prenatal testing according to health policy interests. Personalized risk is discussed as a result of the empirical analysis. It is indicated that increasing risk awareness amongst the public, as well as offering choices, have had unintended consequences. According to doctors, present day parents often want to control risks more than what is considered justified or acceptable. People s hopes to anticipate the health and normality of their future children have exceeded the limits offered by medicine. Individualization of the government of heredity is closely linked to a process that is termed as depolitization. The concept refers to disembedding of medical genetics from its social contexts. Prenatal screening is regarded to be based on individual choice facilitated by neutral medical knowledge. However, prenatal screening within maternity care also has its basis in health policy aims and economical calculations. Methodological basis of the study lies in Michel Foucault s writings on the history of thought, as well as in science and technology studies.

Soporte vital y terapia intensiva.Muerte intervenida

El concepto de muerte intervenida comprende todas aquellas situaciones clínicas en las que la abstención o retiro de algún método de soporte vital en el transcurso de la asistencia médica se propone como un límite en el tratamiento, quedando vinculado el mismo con la llegada de la muerte cardiorrespiratoria tradicional. La presencia de una tecnología médica (soporte vital) común en todos los casos, permite la consideración comprensiva de todo su conjunto. Finalmente, en todos ellos la muerte se vincula a una acción u omisión de la tecnología médica. Una evaluación común de estos casos no sólo tiene una lógica derivada de la operatividad que hizo posible la existencia de estos pacientes sino que además promueve la interpretación verdadera y correcta de los hechos por parte de la sociedad. La reflexión sobre la muerte intervenida como un fenómeno emergente de nuestra cultura resulta imprescindible para que la sociedad se involucre y participe en un tema que le incumbe en forma absoluta y exclusiva.
