ReviewPain management for rheumatoid arthritis and cardiovascular or renal comorbidity.
Pain in rheumatoid arthritis is common, is often multi-factorial and many different pharmacotherapeutic agents are routinely used for pain management. There are concerns that some of the pain pharmacotherapies currently used may increase the risk of adverse events in people with rheumatoid arthritis and concurrent cardiovascular or renal disease. ⋯ There were no trials that specifically compared the efficacy and safety of pain pharmacotherapies for patients with rheumatoid arthritis, with and without comorbid cardiovascular or renal conditions.In the absence of specific evidence in rheumatoid arthritis, current guidelines recommend that NSAIDs be used with caution in the general rheumatoid arthritis population while highlighting the added need for extra vigilance in patients with established cardiovascular disease or risk factors for its development. Current guidelines regarding the use of NSAIDs and opioids in moderate to severe renal impairment should also be applied to the rheumatoid arthritis population.Further research is required to guide clinicians when treating pain in rheumatoid arthritis.

ReviewThe effects of anaesthetic agents on cortical mapping during neurosurgical procedures involving eloquent areas of the brain.
In patients presenting for surgical resection of lesions involving, or adjacent to, the functionally important eloquent cortical areas, it is vital to achieve complete or near complete resection of the pathology without damaging the healthy surrounding tissues.The eloquent areas that the surgeons are concerned with are the primary motor, premotor cortex, supplementary motor cortex and speech areas. If the lesions are within these regions surgeons could either take a biopsy or do a intracapsular decompression without damaging the mentioned areas to avoid postoperative dysfunction. If the lesions are adjacent to the above mentioned areas, the normal anatomy would get distorted. However, proper identification of the above mentioned areas would enable the surgeon to radically remove the tumours. Intraoperative mapping of the cortex with stimulating and recording electrodes is termed as electrophysiological (EP) mapping.The EP mapping of motor, sensory and language cortex is widely employed in the resection of lesions involving or adjacent to the eloquent areas. Both intravenous and inhalational agents are known to affect these EP mapping techniques. ⋯ This review highlights the need for well-designed randomised controlled trials to assess the effect of anaesthetic agents on cortical mapping during neurosurgical procedures involving eloquent areas of the brain.

A fall on the outstretched arm can result in an elbow fracture. Loss of elbow function is a common problem with these fractures and can have major implications for functional capabilities. It is unknown whether early mobilisation can improve functional outcome without increasing complications. ⋯ There is a lack of robust evidence to inform on the timing of mobilisation, and specifically on the use of early mobilisation, after non-surgical or surgical treatment for adults with elbow fractures.There is a need for high quality, well-reported, adequately powered, randomised controlled trials that compare early versus delayed mobilisation in people with commonly-occurring elbow fractures, treated with or without surgery. Trials should use validated upper limb function scales, and assessment should be both short-term (to monitor recovery and early complications) and long-term (at least one year).

ReviewNutritional advice for improving outcomes in multiple pregnancies.
Multiple pregnancies are associated with higher rates of perinatal mortality and morbidity than singleton pregnancies, mainly due to an increased risk of preterm birth. Because fetal outcome is best at a particular range of maternal weight gain, it has been suggested that women with multiple pregnancies should take special diets (particularly high-calorie diets) designed to boost weight gain. However, 'optimal weight gain' in the mother in retrospective studies may merely reflect good growth of her babies and delivery at or near term (both associated with good outcome) and artificially boosting weight gain by nutritional input may confer no advantage. Indeed, a high-calorie diet may be unpleasant to consume, and could lead to long-term problems of being overweight. It is therefore important to establish if specialised diets are actually of benefit to women with multiple pregnancies and their babies. ⋯ There is no robust evidence from randomised trials to indicate whether specialised diets or nutritional advice for women with multiple pregnancies do more good than harm. There is a clear need to undertake a randomised controlled trial.

ReviewNotification and support for people exposed to the risk of Creutzfeldt-Jakob disease (CJD) (or other prion diseases) through medical treatment (iatrogenically).
Creutzfeldt-Jakob disease (CJD) and variant CJD (vCJD) are rare and always-fatal diseases transmissible via certain medical procedures. If a person is exposed to the disease risk through medical treatment, they may need to be notified of this to prevent them passing the risk to others in healthcare settings and to enable additional infection control measures to be put in place for certain procedures. As CJD is incurable, and unable to be screened for or effectively treated, communicating this risk information after an exposure incident may have significant implications for the person at risk, their families/ carers and healthcare professionals. The best ways to notify people of their exposure to the risk of CJD or vCJD, and to support them subsequently, are currently unknown. ⋯ There is insufficient rigorous evidence to determine the effects of interventions to notify people at CJD or vCJD risk and to support them subsequently, or to identify the best approach to communication in these situations. The thematic synthesis can be used to inform policy and practice decisions for communicating with people at risk in the absence of rigorous evaluative studies.
