Bacterial interactions underpin worsening lung function in cystic fibrosis-associated infections.

Unlabelled: Chronic lung infections are the primary cause of morbidity and early mortality in cystic fibrosis (CF) and, as such, have been the subject of a great deal of research. Subsequently, they have become one of the key paradigms for polymicrobial infections. The literature, however, has traditionally focused on the presence of pathogens in isolation or univariate measures like number of species to predict decline of lung function and ignores large swathes of data.

Dramatic Reanimation and Spontaneous Re-Canalization of a Fourth Ventricular Hemorrhage: "REVIVE" Phenomenon.

Background: Intraventricular hemorrhage is a calamitous type of stroke where bleeding into the ventricular system can be defined as: primary, if confined within the ventricles; or secondary, due to intracerebral hemorrhage extending from adjacent parenchyma. Intraventricular blood clot can lead to secondary insult and inflammatory responses that culminates in hydrocephalus as the most common cause of death.

Purpose: THerein, we report a patient with a high modified Graeb scale and low Glasgow coma scale.

Wound Healing Promotion via Release of Therapeutic Metallic Ions from Phosphate Glass Fibers: An and Study.

Biomaterials capable of promoting wound healing and preventing infections remain in great demand to address the global unmet need for the treatment of chronic wounds. Phosphate-based glasses (PG) have shown potential as bioresorbable materials capable of inducing tissue regeneration, while being replaced by regenerated tissue and releasing therapeutic species. In this work, phosphate-glass-based fibers (PGF) in the system PO-CaO-NaO added with 1, 2, 4, 6, and 10 mol % of the therapeutic metallic ions (TMI) Ag, Zn, and Fe were manufactured via electrospinning of coacervate gels.

Characteristics associated with criminal responsibility assessment outcomes among women in Central Canada.

The number of women involved with forensic mental health systems internationally is rising, however, limited research has explored the characteristics of those assessed for criminal responsibility. We investigated the demographic, psychiatric, and criminological characteristics of women recommended as eligible or ineligible for the defence of Not Criminally Responsible (NCR) on account of mental disorder following a criminal responsibility assessment in Central Canada. Data were collected through retrospective chart reviews of court-ordered criminal responsibility assessments for 109 women referred for evaluations between 2003 and 2019.

Selective Depletion of Staphylococcus aureus Restores the Skin Microbiome and Accelerates Tissue Repair after Injury.

Our skin is home to a diverse community of commensal microorganisms integral to cutaneous function. However, microbial dysbiosis and barrier perturbation increase the risk of local and systemic infection. Staphylococcus aureus is a particularly problematic bacterial pathogen, with high levels of antimicrobial resistance and direct association with poor healing outcome.

"There is always a waitlist": The experiences of perinatal women randomized to a waitlist condition in a trial evaluating a novel online self-directed intervention for perinatal anxiety.

Background: Pregnant and postpartum women are at a heightened risk for the development or worsening of mental health problems, with elevated rates of mood and anxiety disorders noted across studies. Timely access to mental health supports is critical during the perinatal period (spanning pregnancy to 1 year postpartum), to mitigate potential negative impacts on mother and child. In general adult populations, a small body of research has highlighted the association between being waitlisted for mental health services with a deterioration in mental health.

Epithelial arginase-1 is a key mediator of age-associated delayed healing in vaginal injury.

Pelvic organ prolapse is a disorder that substantially affects the quality of life of millions of women worldwide. The greatest risk factors for prolapse are increased parity and older age, with the largest group requiring surgical intervention being post-menopausal women over 65. Due to ineffective healing in the elderly, prolapse recurrence rates following surgery remain high.

Cellular Senescence in Acute and Chronic Wound Repair.

Cellular senescence, once thought an artifact of in vitro culture or passive outcome of aging, has emerged as fundamental to tissue development and function. The senescence mechanism importantly halts cell cycle progression to protect against tumor formation, while transiently present senescent cells produce a complex secretome (or SASP) of inflammatory mediators, proteases, and growth factors that guide developmental remodeling and tissue regeneration. Transiently present senescence is important for skin repair, where it accelerates extracellular matrix formation, limits fibrosis, promotes reepithelialization, and modulates inflammation.

Skin Aging in Long-Lived Naked Mole-Rats Is Accompanied by Increased Expression of Longevity-Associated and Tumor Suppressor Genes.

Naked mole-rats (NMRs) (Heterocephalus glaber) are long-lived mammals that possess a natural resistance to cancer and other age-related pathologies, maintaining a healthy life span >30 years. In this study, using immunohistochemical and RNA-sequencing analyses, we compare skin morphology, cellular composition, and global transcriptome signatures between young and aged (aged 3‒4 vs. 19‒23 years, respectively) NMRs.

How do prenatal people describe their experiences with anxiety? a qualitative analysis of blog content.

Background: Despite elevated prevalence rates of prenatal (antenatal) anxiety across studies (13-21%), and prenatal people's use of the Internet to search for pregnancy-related information and support, research investigating prenatal people's experiences with online mental health communication, such as blogs, is lacking. This study examined blog entries focused on anxiety in pregnancy to better understand prenatal people's Internet discourse concerning their experiences with anxiety.

Methods: A Google search using the keywords "anxiety," "pregnant," and "blog" resulted in N = 18 blogs that met inclusion criteria (public blog written in English describing a personal experience with prenatal anxiety in 250 words or more).

Predictors of airway, respiratory, and pulmonary complications following elective anterior cervical discectomy and fusion.

Introduction: Anterior cervical discectomy and fusion (ACDF) is a commonly performed procedure on the cervical spine. While the procedure is generally well tolerated, respiratory and pulmonary complications (RPC) are an unlikely yet possible complication following ACDF. Few previous studies have specifically identified risk factors associated with RPC following ACDF.

Low eligibility for hepatitis B treatment in the Brazilian public health system.

Background: Chronic hepatitis B (CHB) affects 257 million people worldwide. However, the proportion of patients eligible for treatment in the public health system has not been established. This study describes the clinical and laboratory profiles of untreated CHB patients and estimates the eligibility rate for antiviral therapy in accordance with the Brazilian Clinical Protocol and Therapeutic Guidelines.

An evaluation of the quality of online perinatal depression information.

Background: During the perinatal period (including pregnancy and up to 12 months after childbirth), expectant and new mothers are at an elevated risk of developing depression. Inadequate knowledge about perinatal depression and treatment options may contribute to the low help-seeking rates exhibited by perinatal people. The Internet can be an accessible source of information about perinatal depression; however, the quality of this information remains to be evaluated.

Combined Metallomics/Transcriptomics Profiling Reveals a Major Role for Metals in Wound Repair.

Endogenous metals are required for all life, orchestrating the action of diverse cellular processes that are crucial for tissue function. The dynamic wound healing response is underpinned by a plethora of such cellular behaviours, occurring in a time-dependent manner. However, the importance of endogenous metals for cutaneous repair remains largely unexplored.

An Epidermal-Specific Role for Arginase1 during Cutaneous Wound Repair.

Nonhealing wounds are a major area of unmet clinical need remaining problematic to treat. Improved understanding of prohealing mechanisms is invaluable. The enzyme arginase1 (ARG1) is involved in prohealing responses, with its role in macrophages best characterized.

Multimodal Analgesia Decreases Postoperative Opioid Consumption in Living Liver Donation.

Objective: To evaluate the effects of multimodal analgesia on postoperative opioid consumption and perioperative pain management in patients undergoing living liver donation.

Methods: A retrospective study was conducted of 129 patients who underwent living liver donation between 2006 and 2015. Patients were separated into 2 cohorts, pre-multimodal analgesia and multimodal analgesia, to allow intergroup analysis.

A role for estrogen in skin ageing and dermal biomechanics.

The skin is the body's primary defence against the external environment, preventing infection and desiccation. Therefore, alterations to skin homeostasis, for example with skin ageing, increase susceptibility to skin disease and injury. Skin biological ageing is uniquely influenced by a combination of intrinsic and extrinsic (primarily photoageing) factors, with differential effects on skin structure and function.

Human Ex vivo Wound Model and Whole-Mount Staining Approach to Accurately Evaluate Skin Repair.

Chronic non-healing wounds, which primarily affect the elderly and diabetic, are a significant area of clinical unmet need. Unfortunately, current chronic wound treatments are inadequate, while available pre-clinical models poorly predict the clinical efficacy of new therapies. Here we describe a high throughput, pre-clinical model to assess multiple aspects of the human skin repair response.

Cellular benefits of single-use negative pressure wound therapy demonstrated in a novel ex vivo human skin wound model.

Negative pressure wound therapy is a widely used treatment for chronic, nonhealing wounds. Surprisingly, few studies have systematically evaluated the cellular and molecular effects of negative pressure treatment on human skin. In addition, no study to date has directly compared recently available single-use negative pressure modalities to traditional negative pressure devices in a controlled setting.

A traditional Ugandan Ficus natalensis bark cloth exhibits antimicrobial activity against methicillin-resistant Staphylococcus aureus.

Aims: Surgical site, soft tissue and wound infections are some of the most prominent causes of healthcare-associated infections (HCAIs). Developing novel antimicrobial textiles and wound dressings may help alleviate the risk of developing HCAIs. We aimed to determine the antimicrobial efficacy of natural Ugandan bark cloth derived exclusively from the Ficus natalensis tree.

Wound healing: cellular mechanisms and pathological outcomes.

Wound healing is a complex, dynamic process supported by a myriad of cellular events that must be tightly coordinated to efficiently repair damaged tissue. Derangement in wound-linked cellular behaviours, as occurs with diabetes and ageing, can lead to healing impairment and the formation of chronic, non-healing wounds. These wounds are a significant socioeconomic burden due to their high prevalence and recurrence.
