Introduction: Overweight and obesity are growing public health problems worldwide. Both diet and physical activity have been the primary interventions for weight reduction over the past decade. With increasing rates of overweight and obesity, it is evident that a primary focus on diet and exercise has not resulted in sustained obesity reduction within the global population.

Infertility is a widespread issue which is estimated to affect up to 17.5% of the global population. Evidence suggests that the most common causes of female infertility are ovulation disorders (e.

Obesity is a well-established risk factor for infertility. Consequentially, women living with obesity may require fertility treatment to support them to conceive. Due to evidence suggesting obesity is also linked with poorer outcomes following in vitro fertilisation (IVF), local commissioning guidelines on assisted conception recommend a BMI of <30kg/m before IVF can commence.

Objective: The primary aim of this systematic review is to assess the effectiveness of evidence-based healthcare (EBHC) educational interventions on healthcare professionals' knowledge, skills, attitudes, behaviour of EBHC, clinical process and care outcomes. A secondary aim of the review is to assess the effects of important pedagogical moderating factors for EBHC educational interventions.

Method: This systematic review used a forward and backward citation search strategy on the Web of Science platform (date of inception to 28 April 2023).

Globally, hypertension is a significant contributor to cardiovascular, renal diseases and death. Increased dietary salt intake raises the risk of hypertension, which in turn raises the risk of cardiovascular disease, stroke, and kidney disorders. A practical approach to minimising salt intake to lower blood pressure is to use low salt sodium substitutes.

Abdominal aortic aneurysm (AAA) is a condition in which the abdominal aorta becomes enlarged, posing a risk of rupture and life-threatening haemorrhage. Abdominal aortic aneurysm accounts for a substantial number of fatalities worldwide, with mortality rates of up to 80 percent. Abdominal aortic aneurysms are often asymptomatic and are frequently discovered incidentally during tests for unrelated conditions.

There is a long history of BAME under-representation in medical research. Underrepresentation of minority ethnic groups have been assessed by several studies, showing that black and minority ethnic groups were less likely to participate and engage in medical research when compared to white British groups (in relation to education, occupation, health, belief, and attitudes to medical research).There may be several strategies that improve inclusivity, including translation of participant information, culturally specific recruitment, and adaptations to the invitation process.

Leg ulcers pose a significant challenge to healthcare services, requiring effective wound cleansing strategies to promote healing and prevent complications. Large amounts of nursing time is spent managing patients with venous leg ulcers (VLUs), with an average appointment time of approximately 30 minutes. Yet, there is a lack of clear guidance for the treatment of VLUs, with nurses adopting a wide range of cleansing practices.

In the UK, more than 38,000 preterm infants are admitted to Neonatal Intensive Care Units every year. NICU stays, along with perceived vulnerability, have been shown to increase parental stress. Parental stress at this stage of infant development has been associated with a deterioration of the long-term parent-infant relationship.

Background: Virtual reality (VR) as a digital technology has developed rapidly, becoming more realistic, portable, sensory and easier to navigate. Although studies have found VR to be effective for many clinical applications, patients and clinicians have described several barriers to the successful implementation of this technology. To remove barriers for implementation of VR in health care, a greater understanding is needed of how VR can integrate into clinical environments, particularly complex settings such as an intensive care unit.

Delirium is a common presentation after acute stroke. Post-stroke delirium is related to poor recovery, higher rates of mortality, falls, and longer hospital stays. Delirium can lead to challenging behaviour such as anger, aggression, and confusion.

Article Synopsis
  • Researchers investigated how skin pigmentation affects the accuracy of pulse oximetry measurements for oxygen saturation during the COVID-19 pandemic, comparing it to the more reliable method CO-oximetry.
  • The review included 32 studies with over 6,500 participants and found that pulse oximetry tends to overestimate oxygen saturation in individuals with high skin pigmentation, particularly among Black/African American individuals, although the overall biases were small.
  • Despite the small biases, the study highlighted significant imprecision in pulse oximetry results across all subgroups, suggesting that while the method may be generally acceptable, caution is needed regarding its accuracy based on skin tone.

One to two percent of the population in developed countries are affected by chronic heart failure and this increases to greater than 10% in those over 70 years old. Heart failure (HF) predisposes patients to thromboembolic events. Anticoagulants are often used to prevent thromboembolic events in specific patient populations, such as those with atrial fibrillation.

Physical activity is a health behavior contributing to successful weight management. Adults with overweight and obesity find it challenging to meet recommended activity guidelines because of a range of barriers, some of which are not yet fully understood. A barrier receiving limited consideration, compared with other literature within this field, is that of fear.
