#1
Rob Johnson, Brian Munsky
Population modeling aims to capture and predict the dynamics of cell populations in constant or fluctuating environments. At the elementary level, population growth proceeds through sequential divisions of individual cells. Due to stochastic effects, populations of cells are inherently heterogeneous in phenotype, and some phenotypic variables have an effect on division or survival rates, as can be seen in partial drug resistance. Therefore, when modeling population dynamics where the control of growth and division is phenotype dependent, the corresponding model must take account of the underlying cellular heterogeneity...

Iviensan F Manalo, Kathleen E Gilbert, Jashin J Wu
<p>BACKGROUND: Biologic patent expiration, accelerated approval pathways, and business interests of third party payers and the biopharmaceutical industry are driving the development of biosimilars to treat immune-mediated disorders like psoriasis. No studies have investigated dermatologists' familiarity and perspectives of biosimilars.</p> <p>OBJECTIVES: To assess: (1) dermatologists' familiarity with biosimilars and interchangeability and (2) their perspectives toward biosimilar properties, including interchangeability, indication extrapolation, and immunogenicity risk...

EDITORIAL
Aldo Bonaventura, Fabrizio Montecucco, Luca Liberale
In the last few decades, the recommended treatment for coronary artery disease has been dramatically improved by percutaneous coronary intervention (PCI) and the use of balloon catheters, bare metal stents (BMSs), and drug-eluting stents (DESs). Catheter balloons were burdened by acute vessel occlusion or target-lesion re-stenosis. BMSs greatly reduced those problems holding up the vessel structure, but showed high rates of in-stent re-stenosis, which is characterized by neo-intimal hyperplasia and vessel remodeling leading to a re-narrowing of the vessel diameter...

BACKGROUND: Ships should carry mandatory given amounts of medicinal products and basic first aid items, collectively known as the ship's medicine chest. Type and quantities of these products/items are suggested by the World Health Organisation (WHO) and regulated by individual flag states. In countries that lack national legislation, it is assumed that ships should follow WHO indications. An objective difficulty mainly involving vessels of international long-haul routes could be to recognise medicinal compounds obtained in other countries for replacing products used or expired...

BACKGROUND/PURPOSE: Typhoid and paratyphoid fever continue to be important causes of illness and death in parts of Asia, being associated with poor sanitation and consumption of unsafe food and water. Antimicrobial resistance has emerged to traditional first-line drugs, namely, the fluoroquinolones, as well as to third-generation cephalosporins, posing challenges to treatment. Azithromycin has proven to be an effective alternative for treatment of uncomplicated typhoid fever. The purpose of this study was to determine the antimicrobial susceptibility, clinical outcome and serotype distribution pattern of clinical isolates belonging to Salmonella enterica subspecies enterica...

Schizophrenia is a serious mental disease with a high mortality rate and severe social consequences. Due to insufficient knowledge about its etiopathogenesis, curative treatments are not available. One of the most promising new research concepts is the mild encephalitis hypothesis of schizophrenia, developed mainly by Karl Bechter and Norbert Müller. According to this hypothesis, a significant subgroup of schizophrenia patients suffer from a mild, but chronic, form of encephalitis with markedly different etiologies ranging from viral infections, traumas to autoimmune diseases...

Physicians in training are expected to be aware of the newest developments in patient care. Biologic therapies have changed treatment of many diseases by specifically targeting key disease mediators, but patient access to these therapies can be limited. As patents for the first biologic therapies are expiring, the development and approval of products known as biosimilars is rapidly gaining momentum. A biosimilar is a biologic product that is highly similar to a reference product (a licensed biologic product), notwithstanding minor differences in clinically inactive components...

Roselyn Kellen, Gary Goldenberg
As patents for the biologic agents reach their expiration dates, dermatologists must prepare for the coming of biosimilars. These agents have been deemed "highly similar" to their reference products in a process outlined by the US Food and Drug Administration (FDA). In 2016, the FDA approved 3 biosimilars for various indications including plaque psoriasis and psoriatic arthritis. However, biosimilars are not the same as small-molecule generics because they have a complex manufacturing process that makes it impossible to produce identical products to their reference products...

This study was an analysis of the effect of strategic planning on procurement of medicals in Uganda's regional referral hospitals (RRH's). Medicals were defined as essential medicines, medical devices and medical equipment. The Ministry of Health (MOH) has been carrying out strategic planning for the last 15 years via the Health Sector Strategic Plans. Their assumption was that strategic planning would translate to strategic procurement and consequently, availability of medicals in the RRH's. However, despite the existence of these plans, there have been many complaints about expired drugs and shortages in RRH's...

One of the most actual problems of pharmacy is the development of medication forms for external application with complex effects on (gel, emplastro, aerosol, etc.) skin wounds, burns and inflammatory factors. The centuries-old practice of using phyto-preparations (herbal remedies) proved that they have fewer side effects in comparison with synthetic drugs. Despite the wide application of herbal preparations, in the literature there is a little information about their application in development of wound and burn healing modern dosage forms...

In the context of increased pharmaceutical innovation deficits and Big Pharma blockbusters' patent expirations, this paper examines the moderating role of firms' absorptive capacity in external innovation activities of Big Pharma firms. The study indicates a rising interest of Big Pharma in acquisitions of and alliances with biotechnology companies. Unfortunately, this increased interest is not reflected in the number of new drugs generated by Big Pharma. We find that acquisitions of biotech companies have negatively affected Big Pharma firms' innovation performance on average but these acquisitions might have a positive effect at higher levels of acquiring firms' absorptive capacity...

BACKGROUND: The diaphragm is the most important respiratory muscle in humans, and the close relationship between inspired volume and diaphragmatic movement in normal subjects has led to investigations into diaphragmatic activity using ultrasound, during spontaneous breathing and sedative drug infusion. METHODS: A total of 36 consecutive patients undergoing diagnostic procedures under deep propofol sedation were studied. Ultrasound measurements included the following: diaphragmatic thickening end-inspiration (TEI) and end-expiration (TEE)...

The circle system has been in use for more than 100 years, whereas the first clinical application of an anaesthetic reflector was reported just 15 years ago. In the circle system, all breathing gas is rebreathed after carbon dioxide absorption. A reflector, on the other hand, with the breathing gas flowing to and fro, specifically retains the anaesthetic during expiration and resupplies it during the next inspiration. A high reflection efficiency (number of molecules resupplied/number of molecules exhaled, RE 80-90%) decreases consumption...

BACKGROUND: Exogenous replacement of erythropoietin (EPO) by recombinant human EPO has been considered a standard of care for the treatment of anemia in patients with chronic kidney disease for more than 20 years. Genetically engineered biologic proteins derived from human, animal, or microorganism sources are a major area of growth in modern medical care, accounting for one-third of new drug approvals in the past decade. Despite benefit to patients, the use of biologics comes at a significant cost, representing one of the fastest growing segments of strained healthcare budgets around the world...

REVIEW
Simona Deiana, Tommaso Gabbani, Vito Annese
Biologic compounds are obtained from living organisms or cell cultures by means of biotechnology methods. A similar biologic drug, commonly called biosimilar, is a product copied by a native approved biologic drug whose license has expired. Biosimilar drugs usually are marketed at a lower price and provide important financial savings for public healthcare systems. Some differences between biosimilars and original biologic drugs might exist but they are acceptable if they fall within defined "boundaries of tolerance": differences in some features between the two molecules are considered important only if clinical relevant...

With the expiration of patent protection for several originator insulin analog molecules, the availability of insulin analog copies is set to increase. Many regulatory authorities have developed, and continue to refine, guidelines for the approval of biosimilar insulin analogs. Aspects such as the structure, pharmacokinetics and pharmacodynamics, efficacy, safety, and immunogenicity of biosimilar insulin analogs are extensively addressed in these guidelines, but how the biosimilar insulin analog is administered to people with diabetes is not usually a topic...
