A Qualitative Exploration of Peer Supporters' Experiences of Undertaking a Co-Produced Mental Health and Emotional Well-Being Training Programme.

Introduction: Peer supporters play a crucial role in mental health and support services, but their own mental health and emotional well-being are often neglected by themselves, and, frequently, their organisations. Here, we report findings from a qualitative interview study of peer supporters who completed a co-produced emotional well-being training programme.

Method: Ten semi-structured interviews with peer supporters working in the North East of England were conducted to explore their experiences of the training programme.

Microbiological insights and dermatological applications of live biotherapeutic products.

As our understanding of dermatological conditions advances, it becomes increasingly evident that traditional pharmaceutical interventions are not universally effective. The intricate balance of the skin microbiota plays a pivotal role in the development of various skin conditions, prompting a growing interest in probiotics, or live biotherapeutic products (LBPs), as potential remedies. Specifically, the topical application of LBPs to modulate bacterial populations on the skin has emerged as a promising approach to alleviate symptoms associated with common skin conditions.

Spectral characterization of a blue light-emitting micro-LED platform on skin-associated microbial chromophores.

The therapeutic application of blue light (380 - 500nm) has garnered considerable attention in recent years as it offers a non-invasive approach for the management of prevalent skin conditions including acne vulgaris and atopic dermatitis. These conditions are often characterised by an imbalance in the microbial communities that colonise our skin, termed the skin microbiome. In conditions including acne vulgaris, blue light is thought to address this imbalance through the selective photoexcitation of microbial species expressing wavelength-specific chromophores, differentially affecting skin commensals and thus altering the relative species composition.

A survey of multiple candidate probiotic bacteria reveals specificity in the ability to modify the effects of key wound pathogens.

We have evaluated the inhibitory effects of supernatants and lysates derived from several candidate probiotics, on the growth and biofilm formation of wound pathogens, and their ability to protect human primary epidermal keratinocytes from the toxic effects of pathogens. Supernatants (neutralized and non-neutralized) and lysates ( sonication) from GG, and Nissle 1917 were tested for their inhibitory effects against and . The supernatants of and GG reduced the growth of and additionally inhibited growth.

Illuminating microflora: shedding light on the potential of blue light to modulate the cutaneous microbiome.

Cutaneous diseases (such as atopic dermatitis, acne, psoriasis, alopecia and chronic wounds) rank as the fourth most prevalent human disease, affecting nearly one-third of the world's population. Skin diseases contribute to significant non-fatal disability globally, impacting individuals, partners, and society at large. Recent evidence suggests that specific microbes colonising our skin and its appendages are often overrepresented in disease.

Peer supporters' mental health and emotional wellbeing needs: Key factors and opportunities for co-produced training.

Introduction: Peer supporters are a valuable asset to mental health and support services, but their own mental health needs are often overlooked in research and practice. This study explored peer supporters' perceived challenges of maintaining their mental health and emotional wellbeing and co-produced training needs.

Methods: A qualitative approach was used to explore factors affecting peer supporters' mental health and emotional wellbeing.

Nissle 1917 inhibits biofilm formation and mitigates virulence in .

In the quest for mitigators of bacterial virulence, cell-free supernatants (CFS) from 25 human commensal and associated bacteria were tested for activity against . Among these, Nissle 1917 CFS significantly inhibited biofilm formation and dispersed extant pseudomonas biofilms without inhibiting planktonic bacterial growth. eDNA was reduced in biofilms following exposure to Nissle CFS, as visualized by confocal microscopy.

Transitory Shifts in Skin Microbiota Composition and Reductions in Bacterial Load and Psoriasin following Ethanol Perturbation.

Personal care and hygiene regimens may substantially alter the composition of the skin microbiota through direct and indirect mechanisms. An understanding of the timescales of commensal skin microbiota reestablishment following perturbation is required to inform consumer safety risk assessment, and support product development. In the current investigation, the microbiota of the volar and dorsal forearm of 10 volunteers was sampled immediately before and after wiping with 70% ethanol and at up to 24 h afterwards.

Multiple Proteins of GG Are Involved in the Protection of Keratinocytes From the Toxic Effects of .

We have previously shown that lysates of GG confer protection to human keratinocytes against GG inhibits the growth of as well as competitively excludes and displaces the pathogen from keratinocytes. In this study, we have specifically investigated the anti-adhesive action. We have tested the hypothesis that this activity is due to quenching of binding sites on keratinocytes by molecules within the lysate.

A folliculocentric perspective of dandruff pathogenesis: Could a troublesome condition be caused by changes to a natural secretory mechanism?

Dandruff is a common scalp condition, which frequently causes psychological distress in those affected. Dandruff is considered to be caused by an interplay of several factors. However, the pathogenesis of dandruff remains under-investigated, especially with respect to the contribution of the hair follicle.

Gloss Retention on Enamel and Resin Composite Surfaces After Brushing Teeth with Commercial and Modified Dentifrices.

Objectives: We examined the surface gloss and roughness of a dental composite and human enamel after brushing with a new bioactive glass (BCF201) additive designed to treat dentine hypersensitivity.

Methods: We prepared 2 cohorts of samples: a resin-based composite (RBC) and human enamel. Each cohort received 20 000 brushing cycles with Colgate Optic White Enamel (Colgate Optic), Sensodyne Whitening Repair and Protect (Sensodyne), Colgate Enamel Health Sensitivity Relief (Colgate-EN) with and without BCF201 added or Germiphene Gel 7 HT (Gel 7) with and without BCF201 added.

The role of the skin microbiota in the modulation of cutaneous inflammation-Lessons from the gut.

Inflammation is a vital defense mechanism used to protect the body from invading pathogens, but dysregulation can lead to chronic inflammatory disorders such as psoriasis and atopic dermatitis. Differences in microbiota composition have been observed in patients with inflammatory skin conditions compared with healthy individuals, particularly within lesions. There is also increasing evidence accumulating to support the notion that the microbiome contributes to the onset or modulates the severity of inflammatory diseases.

Staphylococcus aureus second immunoglobulin-binding protein drives atopic dermatitis via IL-33.

Background: Staphylococcus aureus is the dominant infective trigger of atopic dermatitis (AD). How this bacterium drives type 2 allergic pathology in the absence of infection in patients with AD is unclear.

Objective: We sought to identify the S aureus-derived virulence factor(s) that initiates the cutaneous type 2-promoting immune response responsible for AD.

Mitigation of the Toxic Effects of Periodontal Pathogens by Candidate Probiotics in Oral Keratinocytes, and in an Invertebrate Model.

The larvae of the wax moth and human oral keratinocytes were used to investigate the protective activity of the candidate oral probiotics GG (LHR), (LR), and K-12 (SS) against the periodontal pathogens (FN), (PG), and (AA). Probiotics were delivered to the larvae (i) concomitantly with the pathogen in the same larval pro-leg; (ii) concomitantly with the pathogen in different pro-legs, and (iii) before inoculation with the pathogen in different pro-legs. Probiotics were delivered as viable cells, cell lysates or cell supernatants to the oral keratinocytes concomitantly with the pathogen.

Osmolyte transporter expression is reduced in photoaged human skin: Implications for skin hydration in aging.

Aging is characterized by the deterioration of tissue structure and function. In skin, environmental factors, for example, ultraviolet radiation (UVR), can accelerate the effects of aging such as decline in barrier function and subsequent loss of hydration. Water homeostasis is vital for all cellular functions and it is known that organic osmolyte transport is critical to this process.

Internalized by Skin Keratinocytes Evade Antibiotic Killing.

causes the majority of skin and soft tissue infections. Half of patients treated for primary skin infections suffer recurrences within 6 months despite appropriate antibiotic sensitivities and infection control measures. We investigated whether internalized by human skin keratinocytes are effectively eradicated by standard anti-staphylococcal antibiotics.

Consumer Safety Considerations of Skin and Oral Microbiome Perturbation.

Microbiomes associated with human skin and the oral cavity are uniquely exposed to personal care regimes. Changes in the composition and activities of the microbial communities in these environments can be utilized to promote consumer health benefits, for example, by reducing the numbers, composition, or activities of microbes implicated in conditions such as acne, axillary odor, dandruff, and oral diseases. It is, however, important to ensure that innovative approaches for microbiome manipulation do not unsafely disrupt the microbiome or compromise health, and where major changes in the composition or activities of the microbiome may occur, these require evaluation to ensure that critical biological functions are unaffected.

Introduction: Full completion of the pre-operative checklist is important for proper preparation of patients before they enter the operating room (OR), thus increasing OR efficiency. It is also critical for patient safety and successful outcomes. According to various literature, full completion of pre-operative checklists varies widely between institutions and occurs anywhere between 21% and 92% of cases.

Children Navigating Parental Cancer: Outcomes of a Psychosocial Intervention.

Research has evidenced a marked increase in the prevalence of cancer among younger people with up to one in five, parenting children under the age of 18 years of age. When a parent is diagnosed with cancer they experience fears and anxieties as they attempt to simultaneously manage their role as a parent, with the illness experience. Parents have expressed difficulties in knowing how to communicate appropriately with their children throughout the illness trajectory as they are primarily focused on protecting or shielding their children from knowledge of the illness.
