Hydrogel for the Treatment of Diabetic Wounds: A Comprehensive Review

Abstract: The management of chronic wounds in diabetic patients is a tough challenge, compounded by elevated amputation rates, frequent recurrence, and increased mortality rates. Nonhealing wounds in people with diabetes are produced by a combination of variables that impede the clearance of injured tissue, stimulate the formation of healthy cell populations, and increase the risk of infection. Traditional wound dressings, such as gauze, films, and bandages, focused solely on hydration and infection prev ention. However, recent scientific investigation has shifted toward advancements in wound healing treatments to overcome the constraints inherent in old methodologies. Hydrogel dressings have surfaced as a particularly enticing and promising avenue for increasing wound healing prowess in the modern medical environment, owing to their remarkable ability for moisture retention, biocompatibility profiles, and therapeutic attributes. The pathophysiology of diabetes wounds has been better studied in recent decades, and a range of functionalized hydrogel dressings have been reported with favourable outcomes, indicating that they have significant potential in healing diabetic wounds. Our approach will comprise a systematic and comprehensive evaluation of the advancements in hydrogel dressing methods related to diabetic wounds. This review presents a strong theoretical foundation for advancing hydrogel dressing technologies and offers suggestions for treating diabetic wound-related problems.

Biophysical and clinical research on acupuncture and moxibustion.

Acupuncture has been used for thousands of years in treating diseases. Meridians and acupoints, on which acupuncture is practiced, have also attracted many research interests. Moxibustion is often used in conjunction with acupuncture as a thermal stimulation on acupoints. Laser, which generates extremely pure light of single wavelengths, is now used widely to stimulate acupoints, because it is noninvasive and easy to manipulate. This special issue contains 1 human research investigating the electrical characteristics of the acupoints, 2 randomized controlled trials (RCTs) evaluating the effect of traditional moxibustion on patients with knee osteoarthritis and lumber disc herniation, respectively, 3 animal studies exploring the effect and mechanism of the traditional moxibustion and laser moxibustion on irritable bowel syndrome (IBS), cyclophosphamide-induced leucopenia, and knee osteoarthritis (OA), respectively, 1 systematic review reviewing the safety of moxibustion, 1 paper describing the design of an electrical thermal stimulation system comparable to moxibustion, and 2 animal researches studying the effect and mechanism of electroacupuncture on disc degeneration and hepatic blood perfusion respectively. The results of these researches showed that acupoints may have special electrical characteristics at pathological status; moxibustion may relieve back pain and improve quality of life in patients with knee OA. Although the two RCTs did not report severe adverse events related to moxibustion, the systematic review found many factors may affect the safety of the moxibustion. The results of these researches also enhanced our knowledge of how traditional moxibustion, laser acupuncture-moxibustion, and electrical-acupuncture work in treating IBS, knee OA, cyclophosphamide-induced leucopenia, disc degeneration, and hepatic blood perfusion. The encouraging findings in this special issue will promote further investigations in the fields of biophysical and clinical research of acupuncture and moxibustion and may encourage more use of moxibustion in clinic. The electrical thermal moxibustion and laser moxibustion might be good substitutes for traditional moxibustion, because they produce thermal effect but with no chocking smoke and smell, thus being more suitable in modern medical environment. However, in this current special issue, researchers only investigated the effect of laser moxibustion on animal and introduced a design of electrical thermal moxibustion device; further clinical research on both moxibustion devices is needed in the future.

종합병원의 공용면적과 기계전기실 면적 프로그램 개선방안

The purpose of this study is to analyze proposed the improvement plan of space-program of public space and mechanical/electrical/equipment area in general hospital. We were researched the chronological changes of total floor area plan of public space and mechanical/Electrical/Equipment area. In addition, compared to space-program and actual design drawings of recently general hospitals. Analyze the trend and characteristic of changes in the general hospital area ratio. The results are as follows. The gross to net ratio was set at 1.45-1.55 but increased to 1.53-1.64 in actual drawings. Thus the total floor area increased or net floor area decreased to secure public area, which means the public area planning suggested by the space program cannot accommodate the public space, vertical circulation and facility space required in the modern medical environment. Thus there is a need to reflect the recent trend, above 1.60. Machine/electricity rooms are judged to be planned above 15% of the total floor net area. However, the suggested standards are the required area at the present moment, which requires continued tests and supplement.

Discussion on Colour Design of Medical Product Based on Visual Negative Afterimage Theory

This paper mainly analyses and discusses the application and significance of the visual negative afterimage on the colour design of medical product based on the visual negative afterimage theory. The design for the colour of medical product based on the visual negative afterimage theory focuses more human orientation in aspect of the visual effect design. The paper also points out that the trend of future design is to organically combine the art, the therapy features and the humanity.The complementary colour equilibrium of the visual negative afterimage will play a more and more important role in the colour design of the medical product. In the modern medical environment, the colour of the medical product has a decisive effect on the information exchange between people and the space environment. Although the visual negative afterimage is common in our daily life, the colour is not taken into consideration in the colour design of the medical product, which will result in negative effects. The colour is a strong and extremely attractive expression tool. Therefore, when the colour is designed for the medical product, it should be applied reasonably. The application of colour must be based on the special function requirements and the use of different people, so as to show its special function and requirements, which not only avoids the negative influence caused by the visual negative afterimage, but also creates a more humanistic atmosphere for the medical environment.

A Weighty Matter: Patient Scales

Patient scales come in a variety of forms, using different technologies and methods to ultimately deliver a reasonable approximation of an object’s or person’s weight. In the medical profession, these measurements are used and recorded in a patient’s record to help monitor well-being, assess the effectiveness of treatment, and determine medication dosage. Scales started out as balances—a beam balanced on a fulcrum with some means of attaching objects to either end was as sophisticated as it got. The object to be weighed was placed on one side and known weights were added to the other side until equilibrium was found. To verify the accuracy of the balance, one had only to trade the places of the object and the weights to see if the equilibrium was once again achieved. This simple device, while very accurate, is hardly practical in the modern medical environment. Eventually the off-center balance was designed. It measured mass using proportionally smaller reference weights, but this balance still had same mechanical principle as the original balance. This highly accurate balance’s only drawback is the inability to verify accuracy. The proportional weight’s accuracy must be verifi ed against another known accurate weight. Losing just one reference weight can render this offcenter balance relatively useless. The Modern Scale The modern mechanical balance beam scale is designed with a reference weight that slides along a beam inscribed with a numerical scale representative of the mass of the object being weighed. This sliding weight, called a poise, is specifi cally calibrated to the beam it slides along. The base of the modern mechanical scale consists of a platform suspended on a rack-and-pinion system, which evenly disperses the weight over the base of the scale. Connecting rods, springs, and levers are used to attach the weighing platform to one end of the balance and the poise slides along the opposite side until the beam is balanced. This same platform system is used in analog and dial scales commonly seen in doctor’s offi ces and medical centers. In this case, the platform is connected to a calibrated coiled spring dial. As more weight is applied, the spring is coiled tighter, and the attached dial twists to a higher number on the face of the gauge.

What aspects of the job have most effect on nurses?

The study reported here compared the influences of psychological constructs (job demands and scheduling control) and objective work characteristics (shiftwork, night‐work and hospital department type) on job satisfaction, organisational commitment, burnout and withdrawal intentions. Our hypothesis was that psychological constructs have a higher influence on work‐related attitudes than objective characteristics of work schedules. In addition to the main effects, we proposed an interactive hypothesis: poor attitudes would result from high demands and low control rather than from other combinations of both psychological variables. Using a sample of 153 hospital nurses in Israel, the hypotheses were generally supported. As night‐work, shiftwork and working in intensive care units are unavoidable characteristics of the modern medical environment, these findings are meaningful for improving the personal adjustment of hospital nurses.

The way we teach medical students professional skills.

This article describes the progressive development of professional skills at the Faculty of Medicine, University of Newcastle, Australia's newest medical school. These professional skills include information gathering (history taking and physical examination), information giving (patient information and education, case history write-up and case presentation) and management (counselling and monitoring) skills, as well as interpersonal, interactional and communication skills which are so important in the modern medical environment. The progressive development of these professional skills and their integration with basic, behavioural and clinical sciences in a problem-based curriculum is believed to be a rational approach to the development of an efficient, effective and caring doctor.
