A narrative review of the success of intramuscular gluteal injections and its impact in psychiatry

Bio-Design and Manufacturing 2018年第3期1卷 161-170页

There are 12 billion injections given worldwide every year. For many injections, the intramuscular route is favoured over the subcutaneous route due to the increased vascularity of muscle tissue and the corresponding increase in the bioavailability of drugs when administered intramuscularly. This paper is a review of the variables that affect the success of intramuscular injections and the implications that these success rates have in psychiatry and general medicine. Studies have shown that the success rates of intended intramuscular injections vary between 32 and 52%, with the rest potentially resulting in inadvertent subcutaneous drug deposition. These rates are found to be even lower for certain at-risk populations, such as obese patients and those on antipsychotic medications. The variables associated with an increased risk of injection failure include female sex, obesity, site of injection, and subcutaneous fat depth. New guidelines and methods are needed in order to address this challenge and ensure that patients receive optimum care. Looking forward, the best way to improve the delivery of intramuscular injections worldwide is to develop uniform algorithms or innovative medical devices to confirm or guarantee successful delivery at the bedside.

Polycystic ovary syndrome (PCOS), a common endocrine disorder with metabolic and reproductive consequences, affects a significant percentage of women of reproductive age. Because of its complexity and impact on the quality of life, PCOS requires timely diagnosis and screening for complications. The most common clinical manifestations of PCOS are hirsutism, hyperandrogenism, acne, irregular cycles, amenorrhea, and anovulation. Although PCOS has different clinical manifestations in women, hyperandrogenism, and anovulation are the most common symptoms. A good medical history, examination, blood tests, and ultrasound findings facilitate the diagnosis of PCOS. Novel treatments have also undergone clinical trials to improve the symptoms of PCOS. However, comprehensive review articles investigating the different communities of this disease are limited, and this review aimed to collect data on the different etiologies of PCOS along with the latest diagnostic methods and the most common and up-to-date treatments for this disease.

Recent Advances in Understanding Plant Myosin Function： Life in the Fast Lane

引用

Molecular Plant 2011年第5期4卷 805-812页

作者： Imogen Sparkes School of Life Sciences Oxford Brookes University Gipsy Lane Oxford OX3 0BP UK

Plant myosins are required for organelle movement, and a role in actin organization has recently come to light. Myosin mutants display several gross morphological phenotypes, the most severe being dwarfism and reduced fecundity, and there is a correlation between reduced organelle movement and morphological defects. This review aims to discuss recent findings in plants relating to the role of myosins in actin dynamics, development, and organelle movement, more specifically the endoplasmic reticulum （ER）. One overarching theme is that there still appear to be more questions than answers relating to plant myosin function and regulation.
