Abstract
Clotting time of lower gastro intestinal bleeding (LGIB) can be reduced by using simple, cost-effective, and naturally occurring halloysite nanotubes (HNTs). The present study aimed to decrease the clotting time by the application of chitosan (CHT) and its microcomposites (MCs) prepared by suspension emulsification technique with HNTs (CHT/HNTs MC). Physicochemical properties, X-Ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and percentage release of ciprofloxacin from CHT/HNTs MCs was evaluated. In-vitro procoagulant activity of CHT, HNTs and their complexes CHT/HNTs MCs was performed on rabbit blood which was confirmed by a rat tail amputation. Direct relation of HNTs was observed for the whole-blood clotting kinetics i.e., 2% HNTs showed a maximum 66.0% increase in the clotting ability as compared with pure CHT. Interestingly, rat-tail amputation studies showed comparative results of CHT, HNTs, and CHT/HNTs MCs. A total of 75% permeation of ciprofloxacin of CHT/HNTs MCs on rat intestinal membrane was observed within 3 h, confirming their SR behavior. Furthermore, improved hemostatic and clotting properties were CHT/HNTs MC1 > CHT/HNTs MC2 > CHT/HNTs MC3 > CHT > HNTs, respectively. Thus, it provided the control of bleeding disorders in LGIB with any antibacterial agents, particularly ciprofloxacin.

Abstract
The present study aimed to explore a new source of montmorillonite and to develop an extraction and purification protocol for its isolation from raw clay samples acquired from the Koh-e-Suleiman mountain range in Pakistan. The process involved the collection of raw clay from the source, identification and quantification of montmorillonite. Granulometric extraction and purification protocols increased the montmorillonite content from 21.8-25.1% in the raw clay to 90.1-93.9% after small-scale extraction and 85.33-89.33% on a larger scale. A techno-economic analysis highlighted the practicality and economic benefits of large-scale extraction for industrial applications. This study highlights the existence of a substantial new source of this valuable clay which is currently used across multiple industries including construction, pottery making, pharmaceuticals, cosmetics and engineering. It is intuitively expected that the large-scale extraction of the material will improve the economic condition of the region by providing employment opportunities to locals and may be a valuable resource for export.

Abstract
Transdermal drug delivery is an emerging field in the pharmaceutical remit compared with conventional methods (oral and parenteral). Microneedle (MN)-based devices have gained significant interest as a strategy to overcome the skin's formidable barrier: the stratum corneum. This approach provides a less invasive, more efficient, patient friendly method of drug delivery with the ability to incorporate various therapeutic agents including macromolecules (proteins and peptides), anti-cancer agents and other hydrophilic and hydrophobic compounds. This short review attempts to assess the various materials involved in the fabrication of MNs as well as incorporation of other excipients to improve drug delivery for novel medical devices. The focus will be on polymers, metals and other inorganic materials utilised for MN drug delivery, as well as their application, limitations and future work to be carried out.

Abstract
It is important that paediatric orthopaedic surgeons recognise that psychological conditions may present with musculoskeletal symptoms. Identification through careful and sensitive history taking is vital. There is a lack of training in this regard in paediatric orthopaedics. We present a series of cases initially referred for a musculoskeletal complaint. Further probing revealed an underlying psychological problem which was neither picked up by the referring physician nor volunteered by the patient. In our opinion, it is important that this training omission is addressed as such psychological problems may be devastating for these individuals and their families.

Abstract
The development of therapeutic dosage (e.g. pharmaceutical) systems is an ongoing process which, in recent times has incorporated several emerging disciplines and themes at timely intervals. While the concepts surrounding dosage forms have developed and evolved, many polymeric excipients remain as the preferred choice of materials over existing counterparts, serving functions as matrix materials, coatings and providing other specific functional properties (e.g. adhesion, controlled release and mechanical properties). There have been, however, developments in the deployment of synthetic polymeric materials (e.g. polycaprolactone, poly lactic co-glycolic acid) when compared to naturally occurring materials (e.g. lactose, gelatin). Advances in pharmaceutical process technologies have also provided novel engineering platforms to develop a host of exciting structure based materials ranging from the nanometer to the macro scales. Some of these structure enabling technologies include spray drying, super critical processing, microfluidics and even wet chemical methods. More recently electrohydrodynamic (EHDA) engineering methods have emerged as robust technologies offering potential to fabricate a plethora of generic structures (e.g. particles, fibres, bubbles and pre-determined patterns) on a broad scale range. This review focuses on key developments using various EHDA technologies for the pharmaceutical and biomaterial remits when selecting synthetic and/or naturally occurring polymers as pharmaceutical (and therapeutic) excipients. In addition, the underlying EHDA process principles are discussed along with key parameters and variables (both materials and engineering). EHDA technologies are operational at ambient conditions and recent developments have also demonstrated their viability for large scale production. These are promising technologies which have potential in established (e.g. films, dressings and microparticles) and emerging scientific themes (e.g. nanomedicines and tissue engineering).

Abstract
The aim of this work was to develop a minimally invasive, impedance spectroscopy method as a novel process analytical technology for monitoring the freeze drying process. This involved the application of planar electrodes, mounted externally to a conventional glass freeze-drying vial, coupled to a high-impedance analyser. The pseudo-relaxation process arising from the composite impedance of the glass wall and product interface was recorded over a frequency range 10(1)-10(6)Hz for a surrogate formulation comprising 2.5% sucrose. Features of the process (i.e. the peak amplitude, C"(peak) and characteristic peak frequency, fpeak) were monitored along with the product temperature data during the entire cycle. It was demonstrated that fpeak is strongly coupled to the temperature of the product (through the dependence of the product temperature on the electrical resistance of the product) whereas C"(peak) is dependent on the extent of ice sublimation and hence can be used to measure the rate of drying and end point of primary drying. This feature provides a distinct advantage over thermocouple measurements which are restricted to end point detection only. The potential to predict the end point of a cycle from C"(peak) vs. time profiles is highlighted in this work.

Abstract
INTRODUCTION Increasing numbers of joint arthroplasty are performed in Britain. While associated complications are well documented, it is not known which of those initiate malpractice claims. METHOD A five-year period was assessed for trends to highlight areas for further improvement in patient information and surgical management. RESULTS The National Health Service paid out almost £14 million for 598 claims. Forty per cent of this was for legal costs. The number of claims increased over time while the rate of successful claims decreased. CONCLUSIONS A failure to consent adequately and to adhere to policies and standard practice can result in a successful malpractice claim. Protecting patients intraoperatively and maintaining high technical expertise while implementing policies and obtaining informed consent decreases the litigation burden.
