COVID-19

This year, Cochrane is continuing to produce new and updated reviews in response to the pandemic. We have blogged about many of them and this blog COVID-19 evidence: a Cochrane round-up brings together a large collection of evidence and resources, starting from when this evidence was first being produced in spring 2020. Plus, we have two blogs on COVID-19 treatments: 1) Treatments for mild COVID-19 and 2) Treatments for moderate to severe COVID-19: Cochrane evidence. Like the reviews themselves, all our blogs are updated to reflect new evidence.

Cochrane Special Collections

Cochrane Special Collections assemble Cochrane Reviews on important topics for the prevention and treatment of COVID-19. They are developed with experts from our global Cochrane network. They are based on World Health Organization interim guidance, and continuously updated. You can find Coronavirus (COVID-19) Special Collections here. Those updated in January 2022 include:

Cochrane Podcasts

Cochrane COVID-19 Podcasts offer short summaries of Cochrane COVID-19 reviews from the authors themselves. A good way to hear the latest Cochrane evidence in under 5 minutes each. Podcasts released in January 2022 include:

Cochrane Clinical Answers

Cochrane Clinical Answers (CCAs) provide a readable, digestible, clinically-focused entry point to rigorous research from Cochrane Reviews. They are designed to be actionable and to inform point-of-care decision-making. Each CCA contains a clinical question, a short answer, and data for the outcomes from the Cochrane Review deemed most relevant to practising healthcare professionals.

You can find Cochrane Clinical Answers related to COVID-19 here.

Cardiovascular disease prevention – sugar consumption

The Cochrane Review High versus low‐added sugar consumption for the primary prevention of cardiovascular disease (January 2022) has found an evidence gap on the impacts of low versus high intake of added sugar on risk factors for cardiovascular disease.

Chronic obstructive pulmonary disease (COPD)

Podcast: Integrated disease management for people with chronic obstructive pulmonary disease.

Dietary advice for disease-related malnutrition

The authors of the Cochrane Review Dietary advice with or without oral nutritional supplements for disease‐related malnutrition in adults (December 2021) report that “We found no evidence of an effect of any intervention on mortality. There may be weight gain with DA [dietary advice] and with DA plus ONS [oral nutritional supplements] in the short term, but the benefits of DA when compared with ONS are uncertain.” Also that “there were too few data for many outcomes to allow meaningful conclusions.” 

7

Exercise training for adults undergoing maintenance dialysis

The Cochrane Review Exercise training for adults undergoing maintenance dialysis (January 2022) has found:

  • Exercise training probably improves depressive symptoms, particularly when the intervention is maintained beyond four months.
  • Exercise training is also likely to improve functional capacity. 
  • Exercise training may improve fatigue, the physical component of quality of life, and pain. 
  • Uncertainty remains about its safety, and its impact (if any) on death, cardiovascular events, or the mental component of health related quality of life.

Low-carbohydrate versus balanced-carbohydrate diets 

A Cochrane Review Low‐carbohydrate versus balanced‐carbohydrate diets for reducing weight and cardiovascular risk (January 2022) has found that, both in people with and people without Type 2 diabetes:

  • “There is probably little to no difference in the weight lost by people following low-carbohydrate weight-reducing diets (also known as ‘low-carb diets’) compared to the weight lost by people following balanced-carbohydrate weight-reducing diets, for up to two years.
  • Similarly, there is probably little to no difference between the diets for changes in heart disease risks, like diastolic blood pressure, glycosylated haemoglobin (HbA1c, a measure of blood sugar levels over 2-3 months) and LDL cholesterol (‘unhealthy’ cholesterol) up to two years.”

You can read more about it in this article Featured review: Low-carbohydrate versus balanced-carbohydrate diets for reducing weight and cardiovascular risk.

Memory rehabilitation for people with Multiple Sclerosis

Cochrane Clinical Answer: In people with multiple sclerosis, what are the effects of memory rehabilitation?

12

Patient-reported outcome measures feedback

Cochrane Clinical Answer: How does feedback to people receiving care and/or healthcare professionals of patient‐reported outcome measures (PROMs) impact outcomes of care? 

13

Smoking cessation

The bottom line of the new Cochrane Review Heated tobacco products for smoking cessation and reducing smoking prevalence (January 2022) is that “heated tobacco probably exposes people to fewer toxins than cigarettes, but possibly more than not using any tobacco.” “No studies reported on cigarette smoking cessation, so the effectiveness of heated tobacco for this purpose remains uncertain.”

14

Stroke

Cochrane Clinical Answer: For adults post stroke, how does more time spent in rehabilitation impact outcomes?

Challenging misinformation

In this free Lifeology course, you can learn what you can do to slow and prevent the spread of misinformation: What is an infodemic and how can we prevent it?: a Lifeology and Cochrane collaboration.

Trusted information needs to be protected on social media as much as misinformation needs to be challenged. Read about the recent removal of Cochrane’s Instagram post and shadowban which highlight the realities of Cochrane’s call against misinformation.

Call to action

Millions of lives could be saved if health evidence and communication is put at forefront of pandemic preparedness. The New Cochrane Convenes report recommends urgent action among those who fund, generate and use evidence to ensure the world is better prepared.

In a call to action, Cochrane is “encouraging other organizations who produce, use, fund or communicate about evidence to join us and support the call to action as a way of helping spread the recommendations further and acting on them”.

“If you lead or are part of an organization, please consider supporting the call to action, or encourage leadership to do so. If you are not affiliated with an organization, you can help by asking your local political leaders, research funders and institutions to support the call to action and by spreading the recommendations.”
