Book Description
The Peritoneal cavity (PC) is the key metastatic site for intra-abdominal malignancies (e.g., GI tract and rectal cancer). PC sites can be used to target several other diseases where lymphatic drug delivery is desired without dumping large amounts of the drug. Till recently, it was thought that treatment with curative intent was impossible but that was challenged by the introduction of cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC), and PIPAC (pressurized intraperitoneal aerosol chemotherapy). Recently, a growing number of preclinical and clinical studies advocate intraperitoneal (IP) chemotherapy as an alternative post-operative therapy for cancer. Although their effectiveness has been proven both experimentally and clinically, there is still little understanding of the role of drug delivery systems (DDS) in targeting drugs in the intraperitoneal (IP) cavity. There are two main challenges one posed by IP cavity where the residence time of a small molecular weight drug (20 kDa) is not sufficiently long to maintain therapeutic effect. This leads to frequent or continuous dosing. Another challenge is device-related or catheter-related problems, such as catheter obstruction, increased risk of infection, and bowel complications. Overall literature shows that the IP site is satisfactorily explored by clinicians but in terms of drug delivery not that much. One can see a clear-cut gap of expertise exchange between the two fields and guidelines from regulatory lawmakers on new medications./ppbr/ppIn summary, challenges like delivery to IP cavity, tumor or organ-specific targeting, efficient tissue penetration, optimal cellular uptake and intracellular residence of a drug, biocompatibility, toxicity, etc can be easily solved by smartly designing functional drug delivery systems (both nano and micro). Nanotechnologies have always fascinated humans for several decades and are now widely explored in the biomedical field. Diverse types of nanoparticles are being explored around the world, some examples include biodegradable nanoparticles, green nanoparticles, polymeric nanoparticles, lipid nanoparticles, metal nanoparticles, graphene, carbon nanotubes, and several others. Now a day's nanoparticles are gaining interest for drug targeting of chemotherapeutic drugs, immunotherapy, and gene delivery. Whereas microparticles can be explored for delayed drug delivery to the peritoneal cavity due to relatively slow removal from IP fluid. Hydrogels or other adhesive drug delivery may help to enhance peritoneal adhesions; thereby maintaining the balance between benefit and risk. Overall, drug delivery systems are key in IP targeting. That means drug delivery specialist and clinician needs to be connected to get the best out of this route of drug administration./ppbr/ppThe present book is a link between pharmaceutical scientists (drug formulators), clinicians, toxicologists, and regulatory experts. This book also provides a new perspective to researchers to divert or guide their research in an optimal way. Exploring Drug Delivery to the Peritoneum serves as a platform for upcoming technologies especially in the medical devices sector to face up and show potential in delivering drugs. It is a chance for commercial partners like insurance companies and the pharma industry to explore this direction./pp/pp

Book Description
Peritoneal surface malignancies (PSM) include a heterogeneous group of primary tumors, like peritoneal mesothelioma, and peritoneal metastases from various origins such as ovarian, gastric, colorectal, or appendicular cancers. Their pathophysiology is complex and still not fully elucidated. Historically, due to their dismal prognosis, peritoneal surface malignancies were considered a terminal condition and treated as such in palliative intent.. Surgery has become pivotal in the treatment of PSM and the development of specific techniques of cytoreductive surgery (peritonectomies, “en-bloc” resection) open up a new era of curative intent treatments.

Book Description
Peritoneal Surgery addresses the response of the peritoneum to injury and the prevention of post-surgical adhesions resulting from general and gynecologic surgery. Adhesions, or scar tissue binding two normally separate surfaces, form when the peritoneum, the membrane covering the abdominal wall and protecting the inner organs, is damaged during surgery, inflammation, or injury. Negative complications from adhesions include pelvic pain, infertility, intestinal obstruction, multiple surgical complications resulting from surgery to remove or pull them apart, and therefore a greater surgical workload and economic burden to the healthcare system. In this book, experts in the field address peritoneal repair, the role of surgical technique to prevent adhesions, adhesion formation, complications of adhesions, and developing technology in the prevention of adhesions.

Book Description
Precision medicine, or personalized medicine, is related to treatment based on the patient’s individual characteristics. To promote this personalized approach, diseases must accurately be diagnosed; specific biomarkers can predict disease evolution and optimize therapy based on each patient's characteristics such as their genetic background, lifestyle and environmental risk factors. Over the years, we have seen a revolution in pharmacotherapy and management of patients receiving personalized medicine, especially when we consider immunotherapy and specific tyrosine kinases inhibitors. Patients with inflammatory diseases, such as monogenetic diabetes and chronic kidney disease, have benefited from the progress made within the last decade related to our understanding of the genetic basis of diabetes. Similarly, patients in precision oncology, with breast, prostate and blood cancer have experienced better overall survival rates with targeted therapy such as trastuzumab (breast cancer), PARPs inhibitors (prostate cancer), imatinib, ibrutinib and venetoclax (leukemia).

Book Description
Emerging Nanotechnologies in Immunology aims to deliver a systematic and comprehensive review of data concerning the nature of interaction and nano-related risks between the nanophamaceuticals currently in the pipeline of S&T development for skin, ocular, and nasal drug delivery, including absorption, toxicity, and the ability to distribute after systemic exposure.The scientific development of manufactured nanomaterials for drug delivery is increasing rapidly. One of the most prominent applications is topical drug delivery, where cutaneous, ocular, and nasal exposure becomes even more relevant. These targets are the first barrier that nanoparticles encounter when in contact with the human body.The contributors addresses a representative set of the broad spectrum of nanopharmaceuticals currently being used, including cationic lipid nanoparticles, polymeric PLGA, PLA nanoparticles, biomacromolecules-based nanoparticles, and other scaffolds tissue engineered skin substitutes. Regulation and risk is also covered, since the safety of these nanophamaceuticals still represents a barrier to their wide innovative use. - Provides the reader with a thorough knowledge of the safety aspects of nanopharmaceuticals which are currently under research - Focuses on the characterization and quantification of the nanopharmaceuticals - Allows readers to understand the correlation between the nature of the materials and their potential nanotoxicological effects - Includes an overview of regulatory aspects related to the R&D of nanopharmaceuticals
