The global population is increasingly reliant on vaccines to maintain population health with billions of doses used annually in immunisation programmes. Substandard and falsified vaccines are becoming more prevalent, caused by both the degradation of authentic vaccines but also deliberately falsified vaccine products. These threaten public health, and the increase in vaccine falsification is now a major concern.

Background: Childhood adversity has previously been associated with overweight and obesity in adult life, but there is a need for larger population-based studies using prospectively obtained adversity trajectories across childhood to confirm these associations. Moreover, childhood adversity may also be associated with underweight, which is less often studied. The aim of the current study is to investigate the association between childhood adversity trajectories from 0-15 years with weight categories in young adult men.

Fluorescent tags are commonly used for imaging of proteins and peptides during biological events; however, the large size of dyes can disrupt protein structure and function, and typically require the use of a chemical spacer. Herein, we report the synthesis of a new class of fluorescent unnatural α-amino acid, containing carbazole side-chains designed to mimic l-tryptophan and thus, readily incorporated into peptides. The amino acids were constructed using a Negishi cross-coupling reaction as the key step and exhibited strong fluorescent emission, with high quantum yields in both organic solvents and water.

Optimal cord management (OCM), defined as waiting at least 60 seconds (s) before clamping the umbilical cord after birth, is an evidence-based intervention that improves outcomes for both term and preterm babies. All major resuscitation councils recommend OCM for well newborns.National Neonatal Audit Programme (NNAP) benchmarking data identified our tertiary neonatal unit as a negative outlier with regard to OCM practice with only 12.

Substandard (including degraded) and falsified (SF) vaccines are a relatively neglected issue with serious global implications for public health. This has been highlighted during the rapid and widespread rollout of COVID-19 vaccines. There has been increasing interest in devices to screen for SF non-vaccine medicines including tablets and capsules to empower inspectors and standardise surveillance.

The early stages of regeneration after injury are similar to those of wound healing. The ascidian Botrylloides diegensis can regenerate an entire adult from a small fragment of vascular tunic following the removal of all zooids in an injury-induced regeneration model. We investigated the molecular and cellular changes following injury to determine the differences between the healing process and the initiation of whole-body regeneration (WBR).

Background: Black ethnic groups are disproportionately affected by sexually transmitted infections (STIs). This review aimed to identify interventions designed to increase engagement with sexual healthcare among people of Black ethnicity as determined by rates of STI testing, adherence to sexual health treatment, and attendance at sexual healthcare consultations. The behaviour change techniques (BCTs) used within identified interventions were evaluated.

Preventing, detecting, and responding to substandard and falsified vaccines is of critical importance for ensuring the safety, efficacy, and public trust in vaccines. This is of heightened importance in context of public health crisis, such as the COVID-19 pandemic, in which extreme world-wide shortages of vaccines provided a fertile ground for exploitation by falsifiers. Here, a proof-of-concept study explored the feasibility of using a handheld Spatially Offset Raman Spectroscopy (SORS) device to authenticate COVID-19 vaccines through rapid analysis of unopened vaccine vials.

Background: The number and complexity of patients being admitted to hospitals is rising and some patients may not receive a full clinical pharmacy review or be reviewed as regularly as needed during their inpatient stay. This is a risk factor for medication errors. Clinical prioritisation identifies patients who are high-risk and most in need of a pharmacist review, targeting finite pharmacy resources to patients who will benefit the most.

The Heck-Matsuda coupling reaction of arenediazonium salts derived from L-phenylalanine with various alkenes has been developed. A two-step process involving the preparation of a tetrafluoroborate diazonium salt from a 4-aminophenylalanine derivative, followed by a palladium(0)-catalysed Heck-Matsuda coupling reaction allowed access to a range of unnatural α-amino acids with cinnamate, vinylsulfone and stilbene side-chains. Analysis of the photophysical properties of these unnatural α-amino acids demonstrated that the ()-stilbene analogues exhibited fluorescent properties with red-shifted absorption and emission spectra and larger quantum yields than L-phenylalanine.

This study's primary objective was to establish differences in beliefs about medicines, levels of asthma-related anxiety and diet and exercise behaviours between parents of children with well controlled and poorly controlled asthma. Secondary objectives were to explore how asthma control might shape relationships between parental cognitions and parenting practices concerning paediatric asthma. Parents of children with asthma aged 10-16 years ( = 310) completed standardised questionnaires measuring beliefs about medicines, parental asthma-related anxiety, parenting attitudes towards child activity, parental feeding and asthma control.

Background: Haemorrhage and subsequent hypovolemia from traumatic injury is a potentially reversible cause of cardiac arrest, as interventions can be made to increase circulatory volume and organ perfusion. Traditionally, intravenous (IV) fluid therapy is recommended for all patients who have experienced a haemorrhagic emergency. There has been some argument, however, that this may not be the most effective treatment as isotonic fluids can dilute coagulation factors and further stimulate bleeding.

Hip-worn triaxial accelerometers are widely used to assess physical activity in terms of energy expenditure. Methods for classification in terms of different types of activity of relevance to the skeleton in populations at risk of osteoporosis are not currently available. This publication aims to assess the accuracy of four machine learning models on binary (standing and walking) and tertiary (standing, walking, and jogging) classification tasks in postmenopausal women.

Nanophotonic platforms in theory uniquely enable < femtomoles of chiral biological and pharmaceutical molecules to be detected, through the highly localized changes in the chiral asymmetries of the near fields that they induce. However, current chiral nanophotonic based strategies are intrinsically limited because they rely on far field optical measurements that are sensitive to a much larger near field volume, than that influenced by the chiral molecules. Consequently, they depend on detecting small changes in far field optical response restricting detection sensitivities.

There are a variety of conditions under which religiosity may be positively or negatively associated with sexual and relationship satisfaction. To better understand these conditions, we conducted two studies using two separate samples: one with individuals (1,695 individuals), and one with couples (481 dyads), to test how sexual sanctification and sexual mindfulness moderate these associations. Across studies sexual mindfulness was positively associated with sexual and relationship satisfaction for the individual and partner, but there was no evidence for moderation; sexual sanctification was consistently associated with higher sexual and relationship satisfaction, and in some cases moderated the association between religiosity and both sexual and relationship satisfaction for women and men.

Background: Attending a sexual health consultation is integral to the effective prevention and treatment of sexually transmitted infections (STIs). However, individuals who may be at risk of STIs do not always do so, leading to an increased risk of STI complications and transmission of infection to others. This systematic review aimed to identify interventions implemented to increase attendance at a pre-booked sexual health clinic appointment and to identify behavioural theory and behaviour change techniques (BCTs), which form the basis for such interventions.

Background: The internet has become an increasingly popular resource among sports medicine patients seeking injury-related information. Numerous organizations recommend that patient educational materials (PEMs) should not exceed sixth-grade reading level. Despite this, studies have consistently shown the reading grade level (RGL) of PEMs to be too demanding across a range of surgical specialties.

The association between religiosity and the construct of sexual passion was examined to see whether religiosity is associated with harmonious, inhibited, and obsessive sexual passion styles. Using multiple regression and checking for interactions between religiosity, gender, broad categories of religion (Catholic, other Christian, other religious, nonreligious), and the three sexual passion styles, the following associations were found: Religiosity had a significant curvilinear relationship to all three sexual passion styles, suggesting an overlap in levels of religiosity and the construct of sexual passion. Optimal sexual passion outcomes were found at both higher and lower levels of religiosity, whereas mid-level religiosity was associated with the less beneficial sexual passion outcomes.
