Emanuele Mauri, Alessandro Sacchetti, Filippo Rossi
The use of polymers as biomaterials has provided significant advantages in therapeutic applications. In particular, the possibility to modify and functionalize polymer chains with compounds that are able to improve biocompatibility, mechanical properties, or cell viability allows the design of novel materials to meet new challenges in the biomedical field. With the polymer functionalization strategies, click chemistry is a powerful tool to improve cell-compatibility and drug delivery properties of polymeric devices...

Feral horses are a significant pest species in many parts of the world, contributing to land erosion, weed dispersal and the loss of native flora and fauna. There is an urgent need to modify feral horse management strategies to achieve public acceptance and long-term population control. One way to achieve this is by using non-surgical methods of sterilisation, which are suitable in the context of this mobile and long-lived species. In this review we consider the benefits of implementing novel mechanisms designed to elicit a state of permanent sterility (including redox cycling to generate oxidative stress in the gonad, random peptide phage display to target non-renewable germ cells and the generation of autoantibodies against proteins essential for conception via covalent modification) compared with that of traditional immunocontraceptive approaches...

Perforation during placement of hysteroscopic microinserts for permanent sterilization occurs in approximately 0.9-2.6% of women undergoing the procedure. Most of the time perforation results in; intraperitoneal placement of the hysteroscopic microinsert requiring laparoscopy or laparotomy for; removal of the device. Herein we present a case of hysteroscopic microinsert perforation with; subsequent retroperitoneal identification of the device. This is the first such case to our knowledge of; retroperitoneal identification and retrieval of a perforated device which required real-time fluoroscopy; during laparoscopy...

Proper functioning wound healing strategies are sparse. Adequate vascular formation to the injured area, as well as replacement of the volume loss, is fundamental in soft tissue repair. Tissue engineering strategies have been proposed for the treatment of these injury sites. Novel cell-free substance, human adipose tissue extract (ATE), has been previously shown to induce in vitro angiogenesis and adipogenesis and in vivo soft tissue formation. This study reports the translation of ATE preparation from laboratory to the operating room (OR)...

BACKGROUND: Intimate partner violence (IPV) may interfere with women's use of preferred forms of contraception, resulting in unwanted pregnancies forcing women to seek permanent sterilization. A history of child sexual abuse (CSA) presages the risk for IPV in adulthood setting the stage for adverse reproductive outcomes. OBJECTIVE: To determine whether CSA and IPV are associated with women's voluntary sterilization when adjusting for demographics and reproductive health history...

Infertility as a result of antineoplastic therapy is becoming a very important issue due to the growing incidence of neoplastic diseases. Routinely applied antineoplastic treatments and the illness itself lead to fertility disorders. Therapeutic methods used in antineoplastic treatment may cause fertility impairment or sterilization due to permanent damage to reproductive cells. The risk of sterilization depends on the patient's sex, age during therapy, type of neoplasm, radiation dose and treatment area. It is known that chemotherapy and radiotherapy can lead to fertility impairment and the combination of these two gives an additive effect...

Exposure of dental abutments to cleaning and sterilizing Radio Frequency Glow Discharge Treatment (RFGDT) triggered greater degrees of human gingival fibroblast (HGF) attachment and spreading over their surfaces. Enhanced cell growth and metabolic activity of such HGFs were found which might lead to improved cellular margins in the smile-revealing "esthetic zone". This investigation, approved by the Institutional Review Board, employed in vitro studies of HGFs to support in vivo clinical applications of differentially treated titanium healing abutments to demonstrate the possible improvements for tissue growth around dental implants...

BACKGROUND: Bangladesh has achieved a low total fertility rate of 2.3. Two-thirds of currently married women of reproductive age (CMWRA) want to limit fertility, and many women achieve their desired fertility before age 30. The incidence of unintended pregnancy and pregnancy termination is high, however. Long-acting reversible contraceptives (LARCs), consisting of the intrauterine device and implant, and permanent methods (PM), including female sterilization and vasectomy, offer several advantages in this situation, but only 8% of CMWRA or 13% of method users use these methods...

BACKGROUND: Nonresorbable substances are still injected to enhance soft-tissue volumes and fill subcutaneous defects. Inflammatory reactions (often termed granulomas) to these materials can be functionally and socially disabling. Most therapeutic options used until now are nonspecific antiinflammatory treatments, targeting an ill-defined immune reaction of undefined cause. The minimally invasive intralesional laser treatment can remove the foreign substance and the inflammatory reaction with an 808-nm diode laser...

Three different single-lumen double-J ureteral stents of different materials were studied and compared after the insertion into a dynamic in vitro model with sterile artificial urine up to 6 months. The aim was to evaluate, at selected time steps of 1, 3, and 6 months, the material performances of the stents in preventing the formation of inorganic encrustations. Morphological, compositional, and qualitative analyses were carried out both before stent insertion and after stent permanence for the different time steps, showing an increasing level of encrustation which remains particularly low in the case of two polyurethane stents...

INTRODUCTION: The large increase in the number of transnasal endoscopic skull base surgeries is a consequence of greater knowledge of the anatomic region, the development of specific materials and instruments, and especially the use of the nasoseptal flap as a barrier between the sinus tract (contaminated cavity) and the subarachnoid space (sterile area), reducing the high risk of contamination. OBJECTIVE: To assess the otorhinolaryngologic complications in patients undergoing endoscopic surgery of the skull base, in which a nasoseptal flap was used...

OBJECTIVE: In Bangladesh, use of long-acting and permanent methods of contraception (LAPM) remains stagnant. Providers' limited knowledge and biases may be a factor. We assessed private providers' knowledge, misconceptions, and general attitudes towards LAPM in two urban areas. The ultimate goal is to shape programs and interventions to overcome these obstacles and improve full method choice in Bangladesh. STUDY DESIGN: Trained data collectors interviewed a convenience sample of 235 female doctors (ob-gyns and general practitioners) and 150 female nurses, from 194 commercial (for-profit) healthcare facilities in Chittagong City Corporation and Dhaka district...

Despite generally low fertility rates in Europe, contraceptive behavior varies to a substantial extent. The dichotomy between Western, and Central and Eastern European countries is particularly relevant. Whereas the former are characterized by the widespread use of modern contraception, the latter show a high prevalence of traditional methods to control fertility. The current study aims to examine whether these differences can be attributed to differences in women's individual status, and in gender inequality at the couple and the country level...
