Abstract
Peripheral arterial disease (PAD) is an occlusive atherosclerotic disease that affects blood vessels and reduces blood flow in the lower limbs. It is estimated that around 200 million people worldwide suffered from it, with a significant number of older people affected. Walking is one of the first-line therapeutic measures for intermittent claudication (IC) in patients with PAD. Supervised Exercise Therapy (SET) programs effectively increase walking distances, however, remain an underutilized tool because they are not readily available in most clinical centres, are extremely expensive, and patient participation is low mainly due to socioeconomic constraints. Home-based Exercise Therapy (HBET) programs are an effective and low-cost alternative to improve both the functional capacity and quality of life (QoL) of patients with IC, as they are performed in the patient’s area of residence and not in the hospital. The WalkingPad program conciliated a smartphone app – the WalkingPad app – with behaviour change intervention to increase walking distances and decrease walking impairment as well to improve QoL at 6 months.

Abstract
Diabetes mellitus is one of the most common diseases around the world, and mainly affects the foot among the human body parts. The main causes of the diabetic foot are neuropathy, peripheral arterial disease and foot deformities; it leads to foot ulceration. Generally, sensory loss, high plantar pressure, foot deformities, inappropriate footwear, blindness, and age are the causing risk factors for developing foot ulceration in diabetic patients. Foot ulceration will result in prolonged hospitalization, high medical expenses, and serious complications with lower extremity amputation. For a long time, appropriate footwear has been recommended by physicians for reducing plantar pressure to prevent foot ulceration, the risk of amputation, and re-ulceration. A review is provided in this article towards the existing literature on the causes and prevalence of the diabetic foot, foot ulceration, off-loading pressure, footwear modification for different types of diabetic foot deformities, and types of footwear and textile materials used in footwear insoles for healing purposes.

Abstract
Purpose
This study aims to facilitate access to vascular disease screening for low-income individuals living in remote and conflict areas based on the results of a pilot trial in Colombia. Also, to increase the amount of diagnosis training of vascular surgery (VS) in civilians.
Design/methodology/approach
The operation method includes five stages: strategy development and adjustment; translation of the strategy into a real-world setting; operation logistics planning; strategy analysis and adoption. The operation plan worked efficiently in this study’s sample. It demonstrated high sensibility, efficiency and safety in a real-world setting.
Findings
The authors developed and implemented a flow model operating plan for screening vascular pathologies in low-income patients pro bono without proper access to vascular health care. A total of 140 patients from rural areas in Colombia were recruited to a controlled screening session where they underwent serial noninvasive ultrasound assessments conducted by health professionals of different training stages in VS.
Research limitations/implications
The plan was designed to be implemented in remote, conflict areas with limited access to VS care. Vascular injuries are critically important and common among civilians and military forces in regions with active armed conflicts. As this strategy can be modified and adapted to different medical specialties and geographic areas, the authors recommend checking the related legislation and legal aspects of the intended areas where we will implement this tool.
Practical implications
Different sub-specialties can implement the described method to be translated into significant areas of medicine, as the authors can adjust the deployment and execution for the assessment in peripheral areas, conflict zones and other public health crises that require a faster response. This is necessary, as the amount of training to which VS trainees are exposed is low. A simulated exercise offers a novel opportunity to enhance their current diagnostic skills using ultrasound in a controlled environment.
Social implications
Evaluating and assessing patients with limited access to vascular medicine and other specialties can decrease the burden of vascular disease and related complications and increase the number of treatments available for remote communities.
Originality/value
It is essential to assess the most significant number of patients and treat them according to their triage designation. This management is similar to assessment in remote areas without access to a proper VS consult. The authors were able to determine, classify and redirect to therapeutic interventions the patients with positive findings in remote areas with a fast deployment methodology in VS.
Plain language summary
Access to health care is limited due to multiple barriers and the assessment and response, especially in peripheral areas that require a highly skilled team of medical professionals and related equipment. The authors tested a novel mobile assessment tool for remote and conflict areas in a rural zone of Colombia.

Abstract
Purpose
The study of vascular mechanics is important. The purpose of this paper is to present an apparatus to measure the biomechanical properties of blood vessels, which can be used for tensile test and fatigue test.
Design/methodology/approach
This equipment consists of a mechanical test platform, a hardware circuit based on FPGA and control software. The torque generated by stepper motor is converted to axial force by ball screw, and the vascular specimen is stretched axially. The tension is measured by a load cell, and the displacement is recorded by a grating displacement sensor.
Findings
According to the results of calibration experiment and stability experiment, the linearity error of the system is 0.251, the hysteresis error is 0.047, the repeatability error is 0.185, the comprehensive error is 0.315 and the standard deviation of the output is less than 0.01 N. A test of animal vascular mechanical properties was carried out, and the results are consistent with the theory.
Originality/value
This apparatus is designed to measure biomechanical properties of blood vessels, and the results of experiments indicate that it is stable and reliable. This work is valuable for studying vascular disease and testing artificial blood vessels.

Abstract
Criminal proceedings can only follow the commission of an offence, made so by statute. If an act is not unlawful, it matters little with what motives a person commits it or the consequences; he is outside the law, i.e. criminal law; civil law might have a remedy, but criminal law does not. Even when a criminal offence is committed, it may contain ingredients without which, what would otherwise be a punishable act, becomes guiltless. Most qualifications to guilt are of longstanding, used by parliamentary draftsmen in a wide range of statutes and have acquired reasonably precise judicial meaning. Most relate to intention—wilfully, intentionally, knowingly—and in a few, judicial extension of the popular meaning and usage of the term has occurred to prevent an innocent stance being simulated by a guilty party. “Knowledge” is such an example. The term has been deliberately widened to cover persons who “shut their eyes” to an offence; where a person deliberately refrains from making enquiries, the results of which he would not care to know, this amounts to having such knowledge— constructive knowledge.
