ABSTRACT
Background The anterior cruciate ligament (ACL) rupture is a common injury with an incidence of 68.6 in 100,000 patients per year. Despite extensive research on ACL rupture, there are insufficient high-quality studies to determine clear treatment strategies for adults lacking the ACL. This study aims to examine the functional differences between surgical and conservative treatment based on the quality of the surgical process. Methodology In this prospective, comparative study, a total of 136 patients aged between 18 and 35 years were enrolled per inclusion and exclusion criteria. Using the lottery system, patients were divided into the following two groups: group A (n = 71) and group B (n = 65). Group A was treated with arthroscopic ACL reconstruction and rehabilitation, whereas group B was treated conservatively (rehabilitation). Patient data, including age, sex, body mass index, International Knee Documentation Committee (IKDC) score, Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner Activity Level (TAL) score, and complications were recorded and compared. Results The demographic data were comparable, where males had dominancy in both groups. The mean IKDC and KOOS scores were higher in group A at all follow-ups compared to group B. The scores gradually increased at every follow-up till six months. At the final follow-up, the IKDC and KOOS scores were higher in group A than in group B, and a significant difference was observed among both groups. The TAL score also gradually increased at every follow-up till 6 months. At the final follow-up, the TAL score was higher in group A than in group B, with a significant difference between the two groups (p = 0.0032). Complications in both groups were comparable. Conclusions This study showed that both the conservatively treated group and the rebuilt group had identical outcomes, with the exception of the conservative group having greater objectively quantifiable instability. However, at the final follow-up, patients reported feeling just as satisfied with their knee without surgery, demonstrating no subjective difference in activity levels or functional outcomes. Therefore, non-athletes with an ACL-insufficient knee should still choose conservative treatment.
ABSTRACT
Inspired by biology, significant advances have been made in the field of electronic skin (eSkin) or tactile skin. Many of these advances have come through mimicking the morphology of human skin and by distributing few touch sensors in an area. However, the complexity of human skin goes beyond mimicking few morphological features or using few sensors. For example, embedded computing (e.g. processing of tactile data at the point of contact) is centric to the human skin as some neuroscience studies show. Likewise, distributed cell or molecular energy is a key feature of human skin. The eSkin with such features, along with distributed and embedded sensors/electronics on soft substrates, is an interesting topic to explore. These features also make eSkin significantly different from conventional computing. For example, unlike conventional centralized computing enabled by miniaturized chips, the eSkin could be seen as a flexible and wearable large area computer with distributed sensors and harmonized energy. This paper discusses these advanced features in eSkin, particularly the distributed sensing harmoniously integrated with energy harvesters, storage devices and distributed computing to read and locally process the tactile sensory data. Rapid advances in neuromorphic hardware, flexible energy generation, energy-conscious electronics, flexible and printed electronics are also discussed. This article is part of the theme issue 'Harmonizing energy-autonomous computing and intelligence'.
ABSTRACT
The nanoparticulate formulation of lipomer doxycycline hydrochloride (lipomer DH) has been synthesized for the treatment of Brucellosis to increase efficacy of the drug. The present study was undertaken to determine the intravenous safety of blank lipomer and Lipomer DH in terms of maximum tolerated dose in rats. It was observed that blank lipomer and lipomer DH were safe when administered intravenously at doses 2000 mg/kg Bw and 18 mg/kg bw respectively.
