The Cochrane Pain, Palliative and Supportive Care Group has more than 270 active full reviews in the Cochrane Library. They added to these in May 2022 with a new review of the effects of giving antiemetics to adults receiving intravenous opioids in acute care. We asked lead author, Michael Gottlieb from the Department of Emergency Medicine at Rush University Medical Center in Chicago, USA, to tell us more in this podcast.

Alongside the dozens of Cochrane Reviews of possible treatments for dementia, are reviews looking at how to diagnose it, including the use of a phone or video call rather than an in-person visit. In April 2022, we added a new review to these, evaluating the accuracy of remote cognitive assessment and we asked Amy Elliott to speak with lead author and colleague at the University of Leicester in England, Lucy Beishon about the review for this podcast.

Alongside quantitative evidence on the effects of healthcare interventions, it's important to have qualitative evidence on people's views about these interventions, particularly if they are delivered at the population level. This is the case with mass drug administration for filariasis, which is a parasitic disease that can result in swollen limbs and disability and, in February 2022, the Cochrane Infectious Diseases group, based at the Liverpool School of Tropical Medicine in the UK, published a qualitative evidence synthesis on community views about this intervention.

The Cochrane programme of reviews for COVID-19 covers both the diagnosis and treatment of the disease and reviews are being updated as new evidence becomes available. Among these is a review of chest imaging for diagnosing the condition, and its fourth version was published in May 2022. We asked the lead author, Sanam Ebrahimzadeh, from The Ottawa Hospital Research Institute in Canada, to describe the latest findings in this podcast.

Cochrane Musculoskeletal has produced more than 200 systematic reviews of interventions for the prevention, treatment or rehabilitation of musculoskeletal disorders. These were added to in March 2022 with a new review of the effects of a type of surgery called knee arthroscopy. In this podcast, Ray Moynihan from Bond University in Australia, talks with lead author, Denise O'Connor, from Monash University and Cabrini Hospital in Melbourne.

The most common type of stroke is one in which a large artery in the brain gets blocked by a blood clot and there are dozens of Cochrane reviews of various treatments for these ischaemic strokes. One of these reviews, looking at the effects of endovascular thrombectomy and intra-arterial interventions, was updated in June 2021 and lead author, Melinda Roaldsen from the Arctic University of Norway in Tromsø, briefly describes the new findings in this  podcast.

Cochrane has published several reviews of the effects of interventions to reduce self-harm and suicide and, in the first few months of 2021, three of these were updated covering pharmacological and psychosocial interventions for self-harm in children, adolescents and adults. We asked two of the authors, Keith Hawton and Katrina Witt to tell us about the findings in this podcast.

Note: This recording covers three reviews:
- Interventions for children and adolescents who self-harm
- Psychosocial interventions for adults who self-harm
- Drugs and natural products for self-harm in adults

Cochrane is preparing a series of reviews to help decision makers deal with the COVID-19 pandemic and its impact. We are keeping these up to date as new evidence becomes available and the review of using signs and symptoms to diagnose whether someone has the disease has been updated for the second time. The review was first published in June 2020 and the most recent update was published in May 2022. Here's the lead author, Thomas Struyf from the Katholieke Universiteit Leuven in Belgium, to tell us about the latest findings.

There are now more than two dozen Cochrane reviews of high priority topics relevant to COVID-19, which are being kept up to date as new evidence becomes available. In March 2022, we published updated findings on the effects of anticoagulants and we asked lead author, Ronald Flumignan from the Federal University of Sao Paulo in Brazil to summarize the evidence in this podcast.

Cochrane is producing a growing series of reviews on the care of patients with COVID-19. In January 2022, we published a new review of a group of treatments called interleukin-1 blocking agents and we asked lead author, Mauricia Davidson from Cochrane France, to tell us about the findings.

The Cochrane Neonatal Group has produced more than 400 reviews over the last two decades and, in February 2022, they published their overview of reviews of treatments for rapid breathing in babies. We asked two of the co-authors, Olga Romantsik and Matteo Bruschettini from Skåne University Hospital in Lund, Sweden, to tell us about the latest findings.

Every year, approximately 14 million around the world have a stroke, and the Cochrane Stroke Group has produced more than 200 reviews in the last 25 years. In November 2021, they updated the review of information provision for stroke survivors and their carers, and two of the authors, Tom Crocker and Lesley Brown from the Bradford Teaching Hospitals NHS Foundation Trust in the UK discuss the latest findings in this podcast.

The Cochrane Gynaecology and Fertility Group had produced approximately 100 reviews relevant to in vitro fertilisation, or IVF and updates these in light of new evidence. The second update of their review of a technique called endometrial scratching was published in June 2021 and, in this podcast, Dr Rob Axe speaks with one of the authors Dr Sarah Armstrong, from the University of Sheffield in the UK about the technique and their latest findings on its effects.

Some new-born babies will suffer from jaundice and there are several Cochrane reviews of possible ways to prevent or treat it. These were added to in July 2021 with a new review of the effects of sunlight. We asked the review's lead author, Delia Horn from the Larner College of Medicine at the University of Vermont in the USA, to tell us about the importance of this topic and the findings of the review.

Over the last year, Cochrane Neuro-Oncology have been publishing a series of new systematic reviews on priority topics for the brain tumour community. These were selected from the most important unanswered questions identified by patients, the public and practitioners. In this podcast, Kathreena Kurian from the University of Bristol in the UK tells us about one of the reviews, which was published in March 2022, looking at the evidence on some of the tests that might help in planning the treatment of patients with a glioma.

Cochrane Stroke has produced more than 70 systematic reviews of pharmacological interventions that might improve the recovery of patients after stroke. In this podcast, co-authors Simiao Wu and Xing Hua, both from the West China Hospital at Sichuan University, in Chengdu, China, talk about the November 2021 update for one of these, which looks at the effects of selective serotonin uptake inhibitors on recovery from stroke.

The single most common, preventable cause of in-hospital death is a hospital-acquired venous thromboembolism; making this an important target for prevention when people are admitted to hospital. An updated Cochrane Review from January 2022 looks at the evidence for one of the possible interventions, which combines anti-coagulant drugs with intermittent pneumatic leg compression to prevent these blood clots. Stavros Kakkos from the University of Patras in Greece tells us more.

Most Cochrane Reviews take their evidence from randomized trials of the effects of healthcare interventions, and these trials need to be efficient and reliable. A challenge for many trials is ensuring that people who agree to join the study are followed up, so that their outcomes are measured. An updated Cochrane Methodology Review from March 2021 looks at research into ways to improve this retention, and our Podcast Editor, Mike Clarke, spoke with lead author, Katie Gillies, from the University of Aberdeen in Scotland about the review in this podcast.
