Hyperbaric oxygen therapy has been proposed as a method to treat traumatic brain injuries. The combination of pressure and increased oxygen concentration produces a higher content of dissolved oxygen in the bloodstream, which could generate a therapeutic benefit for brain injuries. This dissolved oxygen penetrates deeper into damaged brain tissue than otherwise possible and promotes healing. The result includes improved cognitive functioning and an alleviation of symptoms. However, randomized controlled trials have failed to produce consistent conclusions across multiple studies. There are numerous explanations that might account for the mixed evidence, although one possibility is that prior evidence focuses primarily on statistical significance. The current analyses explored existing evidence by calculating an effect size from each active treatment group and each control group among previous studies. An effect size measure offers several advantages when comparing across studies, as it can be used to directly contrast evidence from different scales, and it provides a proximal measure of clinical significance. When exploring the therapeutic benefit through effect sizes, there was a robust and consistent benefit to individuals who underwent hyperbaric oxygen therapy. Placebo effects from the control condition could account for approximately one-third of the observed benefits, but there appeared to be a clinically significant benefit to using hyperbaric oxygen therapy as a treatment intervention for traumatic brain injuries. This evidence highlights the need for design improvements when exploring interventions for traumatic brain injury and the importance of focusing on clinical significance in addition to statistical significance.Lung-protective ventilation significantly reduces mortality in patients with acute respiratory distress syndrome, but do the advantages of this approach transfer from the intensive care unit to the operating room?Infants born prematurely are often discharged from hospital before 37 weeks post-menstrual age. While breastfeeding will meet all the nutritional requirements of full-term infants, these preterm infants may need enhanced levels of protein, minerals and possibly energy to ensure optimum growth, bone mineralisation and neurological development. To meet these additional nutrient needs in the neonatal unit, it is currently recommended that multinutrient breast milk fortifier is added to maternal breast milk. Wnt antagonist There may also be benefits in continuing to provide fortified milk after discharge, potentially including improved growth and preserving breastfeeding, and this is increasingly becoming a recognised practice in some neonatal units. This article presents the discussion and consensus of a multidisciplinary panel of neonatologists, neonatal dietitians, a GP and a neonatal outreach sister. The aim is to develop guidance on providing safe and effective nutritional supplementation for preterm infants after discharge in order to maintain optimal growth. This guidance is aimed at community healthcare staff and is based on the limited evidence available, using shared best practice and expertise.The PARTNER 3 and Evolut LRT trials have provided the evidence base for transcatheter aortic valve implantation in low-risk patients. However, there are still issues with durability, long-term follow up and complications before their widespread use can be considered appropriate in this group.The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread and have grave health and socioeconomic consequences worldwide. Researchers have raced to understand the pathophysiological mechanisms underpinning the disease caused by SARS-CoV-2 so that effective therapeutic targets can be discovered. This review summarises the key pharmacotherapies that are being investigated for treatment of COVID-19, including antiviral, immunomodulator and anticoagulation strategies.The European Medicines Agency's Pharmacovigilance Risk Assessment Committee has issued statements regarding limiting the use of high-dose oestradiol creams by women experiencing the genitourinary syndrome of menopause, and such statements carry much medicolegal weight. Although a low dose is most often used, some clinicians opt to use higher dose creams with close monitoring of the patient. The committee should publish the evidence behind these statements or amend its official position.Pregnancy is a hypercoaguable state. As part of the multidisciplinary team on labour ward, the anaesthetist plays a role particularly in advising the women and the obstetric team regarding the timing and even choice of regional analgesia given the potential risk of complications, as this may be affected by the anticoagulation treatment pregnant women may be on. It is important to understand the type of anticoagulation regimens parturients might be on and what sort of risk assessment they must undergo, as this has obstetric and anaesthetic implications. Although a rare presentation, management of women with mechanical prosthetic heart valves who are pregnant requires detailed and highly specialised care in tertiary care centres with a well-developed multidisciplinary team and pathway. Despite their rare presentation, it is important to understand the intricate and complex management that these women require as they have a high morbidity and mortality rate.Management of cutaneous T-cell lymphoma should provide a holistic approach to a patient's wellbeing. Treatments depend on the stage of lymphoma. Patients with the early stages tend to have a near-normal life expectancy. Management should be aimed at improving the extent of disease and reducing symptoms with minimal therapeutic adverse effects. Skin-directed treatments are preferred and may be used in combination with treatments for symptom relief such as anti-pruritic medication. In advanced stages of disease where the median life expectancy is reduced the aims are also to prevent disease progression and prolong life, and this requires a multidisciplinary approach. Symptom control remains important as patients often have painful, itchy disfiguring lesions which greatly impact on health-related quality of life. National and international guidelines provide stage-related treatment options to be considered with first-line options followed by subsequent second-line therapies. All are listed in no particular order of preference and are chosen according to patients' needs and expertise of the treating centre.
