Sodium and Health: Old Myths and a Controversy Based on Denial.

PURPOSE OF REVIEW: The scientific consensus on which global health organizations base public health policies is that high sodium intake increases blood pressure (BP) in a linear fashion contributing to cardiovascular disease (CVD). A moderate reduction in sodium intake to 2000 mg per day helps ensure that BP remains at a healthy level to reduce the burden of CVD. RECENT FINDINGS: Yet, since as long ago as 1988, and more recently in eight articles published in the European Heart Journal in 2020 and 2021, some researchers have propagated a myth that reducing sodium does not consistently reduce CVD but rather that lower sodium might increase the risk of CVD. These claims are not well-founded and support some food and beverage industry's vested interests in the use of excessive amounts of salt to preserve food, enhance taste, and increase thirst. Nevertheless, some researchers, often with funding from the food industry, continue to publish such claims without addressing the numerous objections. This article analyzes the eight articles as a case study, summarizes misleading claims, their objections, and it offers possible reasons for such claims. Our study calls upon journal editors to ensure that unfounded claims about sodium intake be rigorously challenged by independent reviewers before publication; to avoid editorial writers who have been co-authors with the subject paper's authors; to require statements of conflict of interest; and to ensure that their pages are used only by those who seek to advance knowledge by engaging in the scientific method and its collegial pursuit. The public interest in the prevention and treatment of disease requires no less.

Prevalence of unmet needs for spasticity management in care home residents in the East Midlands, United Kingdom: a cross-sectional observational study.

OBJECTIVE: To establish the prevalence of unmet need for spasticity management in care home residents in two counties of the United Kingdom. DESIGN: Cross-sectional observational study with a six-month follow-up arm for participants with identified unmet needs. SETTING: 22 care homes in Derbyshire and Nottinghamshire. SUBJECTS: 60 care home residents with upper motor neuron syndrome-related spasticity. INTERVENTIONS: No intervention. When unmet needs around spasticity management were identified, the participant's general practitioner was advised of these in writing. MAIN MEASURES: Resistance to Passive Movement Scale to assess spasticity; recording of (a) the presence of factors which may aggravate spasticity, (b) potential complications of spasticity, (c) spasticity-related needs and (d) current interventions to manage spasticity. Two assessors judged the presence or absence of needs for spasticity management and whether these needs were met by current care. RESULTS: Out of 60 participants, 14 had no spasticity-related needs; 46 had spasticity-related needs; 11 had needs which were being met by current care and 35 participants had spasticity-related needs at baseline which were not being met by their current care. These were most frequently related to the risk of contracture development or problems with skin hygiene or integrity in the upper limb. In total, 6 participants had one or more pressure sores and 35 participants had one or more established joint contractures. A total of 31 participants were available for follow-up. Informing general practitioners of unmet needs resulted in no change to spasticity management in 23/31 cases. CONCLUSION: Care home residents in this study had high levels of unmet need for spasticity management.

Progressive multifocal leukoencephalopathy masquerading as cerebellar infarction.

Progressive neurological signs and symptoms, in immunocompromised individuals, could be due to progressive multifocal leukoencephalopathy (PML). We report the case of a patient who present a stroke unit with symptoms that were consistent initially with a posterior circulation stroke. Prior chemotherapy with Rituximab, for a lymphoma, had predisposed the patient to infection with the JC virus. Physicians need to be aware of the condition, and patients need to aware of these risks of chemotherapy.

Does looped nasogastric tube feeding improve nutritional delivery for patients with dysphagia after acute stroke? A randomised controlled trial.

BACKGROUND: nasogastric tube (NGT) feeding is commonly used after stroke, but its effectiveness is limited by frequent dislodgement. OBJECTIVE: the objective of the study was to evaluate looped NGT feeding in acute stroke patients with dysphagia. METHODS: this was a randomised controlled trial of 104 patients with acute stroke fed by NGT in three UK stroke units. NGT was secured using either a nasal loop (n = 51) or a conventional adhesive dressing (n = 53). The main outcome measure was the proportion of prescribed feed and fluids delivered via NGT in 2 weeks post-randomisation. Secondary outcomes were frequency of NGT insertions, treatment failure, tolerability, adverse events and costs at 2 weeks; mortality; length of hospital stay; residential status; and Barthel Index at 3 months. RESULTS: participants assigned to looped NGT feeding received a mean 17% (95% confidence interval 5-28%) more volume of feed and fluids, required fewer NGTs (median 1 vs 4), and had fewer electrolyte abnormalities than controls. There was more minor nasal trauma in the loop group. There were no differences in outcomes at 3 months. Looped NGT feeding cost 88 pounds sterling more per patient over 2 weeks than controls. CONCLUSION: looped NGT feeding improves delivery of feed and fluids and reduces NGT reinsertion with little additional cost.

Is looped nasogastric tube feeding more effective than conventional nasogastric tube feeding for dysphagia in acute stroke?

BACKGROUND: Dysphagia occurs in up to 50% of patients admitted to hospital with acute strokes with up to 27% remaining by seven days. Up to 8% continue to have swallowing problems six months after their stroke with 1.7% still requiring enteral feeding. Nasogastric tubes (NGT) are the most commonly used method for providing enteral nutrition in early stroke, however they are easily and frequently removed leading to inadequate nutrition, early PEG (Percutaneous Endoscopic Gastrostomy) insertion or abandoning of feeding attempts. Looped nasogastric tube feeding may improve the delivery of nutrition to such patients. METHODS: Three centre, two arm randomised controlled trial, with 50 participants in each arm comparing loop (the intervention) versus conventional nasogastric tube feeding. The primary outcome measure is proportion of intended feed delivered in the first 2 weeks. The study is designed to show a mean increase of feed delivery of 16% in the intervention group as compared with the control group, with 90% power at a 5% significance level. Secondary outcomes are treatment failures, mean volume of feed received, adverse events, cost-effectiveness, number of chest x-rays, number of nasogastric tubes and tolerability.
