Strategic Inhibition of CHRM Autoantibodies: Molecular Insights and Therapeutic Potentials in Long COVID.

In addition to the conventional symptoms reported for COVID-19, it is becoming increasingly clear that patients with long COVID are exhibiting new symptoms due to the emergence of autoantibodies against G-protein-coupled receptors, among which human muscarinic cholinergic receptors (CHRMs) have been prominently reported. With a chronic condition such as long COVID, additional symptoms caused by anti-CHRM autoantibodies (AAbs) have proven to be an added burden on these patients. The origins of these AAbs, their interactions with, and effects on the function of neural and non-neural cells within the nervous system have remained unknown.

Potent phytoceuticals cocktail exhibits anti-inflammatory and antioxidant activity on LPS-triggered RAW264.7 macrophages in vitro.

Chronic inflammatory conditions, which include respiratory diseases and other ailments, are characterized by persistent inflammation and oxidative stress, and represent a significant health burden, often inadequately managed by current therapies which include conventional inhaled bronchodilators and oral or inhaled corticosteroids in the case of respiratory disorders. The present study explores the potential of Vedicinals®9 Advanced, a polyherbal formulation, to mitigate LPS-induced inflammation and oxidative stress in RAW264.7 mouse macrophages.

An allosteric inhibitor of RhoGAP class-IX myosins suppresses the metastatic features of cancer cells.

Aberrant Ras homologous (Rho) GTPase signalling is a major driver of cancer metastasis, and GTPase-activating proteins (GAPs), the negative regulators of RhoGTPases, are considered promising targets for suppressing metastasis, yet drug discovery efforts have remained elusive. Here, we report the identification and characterization of adhibin, a synthetic allosteric inhibitor of RhoGAP class-IX myosins that abrogates ATPase and motor function, suppressing RhoGTPase-mediated modes of cancer cell metastasis. In human and murine adenocarcinoma and melanoma cell models, including three-dimensional spheroid cultures, we reveal anti-migratory and anti-adhesive properties of adhibin that originate from local disturbances in RhoA/ROCK-regulated signalling, affecting actin-dynamics and actomyosin-based cell-contractility.

The impact of early surgical ventricular septal defect repair on parenting behavior and mother-child relationship: a prospective longitudinal study.

Introduction: Many studies have investigated the impact of congenital heart defects (CHD) on child development. However, because CHD not only affects the child and his or her development but, also the entire family, family functioning after pediatric cardiac surgery is of increasing research interest. This prospective childhood-adolescence case-control study aimed to examine differences and changes in parenting behavior and mother-child relationship quality after early surgical repair of an isolated ventricular septum defect (VSD) compared to non-affected controls.

Systematic review: the impact of maternal pre-and postnatal cannabis use on the behavioral and emotional regulation in early childhood.

Prenatal exposure to alcohol and tobacco has been associated with child regulatory abilities and problems, but less is known about the associations with cannabis exposure. This review seeks to address this gap primarily focusing on the effects of maternal cannabis use on the child. Thus, we investigate the association between pre- and postnatal cannabis exposure of the child and regulatory abilities and problems, as well as the underlying neurobiological mechanisms potentially mediating the associations.

Undergraduate nursing student perceptions of the unexpected death of a classmate: A qualitative study.

Experiencing the unexpected death of a classmate is distressing and overwhelming for college-aged students, particularly those in a nursing major who spend a tremendous amount of time together within the classroom and high-stress clinical settings. Previous studies have identified ways to help nursing students understand their grief reactions in response to patient-critical illness or death. However, data related to how the sudden death of a classmate impacts traditional nursing students has been minimally studied.

Unraveling the enigma of long COVID: novel aspects in pathogenesis, diagnosis, and treatment protocols.

Long COVID, now unmistakably identified as a syndromic entity encompassing a complex spectrum of symptoms, demands immediate resolution of its elusive pathogenic underpinnings. The intricate interplay of diverse factors presents a complex puzzle, difficult to resolve, and thus poses a substantial challenge. As instances of long COVID manifest by repeated infections of SARS-CoV-2 and genetic predisposition, a detailed understanding in this regard is needed.

A retrospective cohort study on early antibiotic use in vaccinated and unvaccinated COVID-19 patients.

The bacteriophage behavior of SARS-CoV-2 during the acute and post-COVID-19 phases appears to be an important factor in the development of the disease. The early use of antibiotics seems to be crucial to inhibit disease progression-to prevent viral replication in the gut microbiome, and control toxicological production from the human microbiome. To study the impact of specific antibiotics on recovery from COVID-19 and long COVID (LC) taking into account: vaccination status, comorbidities, SARS-CoV-2 wave, time of initiation of antibiotic therapy and concomitant use of corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs).

Changes in substance use and engagement in gaming/gambling in persons with severe mental illness during the COVID-19 pandemic and earthquakes: a community study in two points.

Introduction: External stressors, such as COVID-19 pandemic and earthquake, can cause an increase in substance use and addictive behavior in persons with severe mental illnesses (SMI). We analyzed the changes and predictors of substance use and addictive behavior in SMI during these double disasters in Croatia.

Methods: Questionnaires exploring the presence of substance or behavior addiction disorder, mental ill health [Depression Anxiety Stress Scales-21 (DASS-21), Insomnia Severity Index (ISI), Perceived Stress Scale (PSS), Obsessive-Compulsive Inventory-Revised], coping mechanisms, and perceived social support [Multidimensional Scale of Perceived Social Support (MSPSS)] were administered among 90 participants with SMI included in the RECOVER-E study in May/June 2020 (first COVID-19 wave, Zagreb earthquake) and in December 2020/January 2021 (second COVID-19 wave, Petrinja earthquake).

Long-Term Effects of Child Early Surgical Ventricular Septal Defect Repair on Maternal Stress.

The ventricular septal defect (VSD) represents the most common congenital heart defect (CHD). The diagnosis of and cardiac surgery for their child's VSD are highly stressful experiences for parents; especially mothers, who are at risk of developing long-lasting stress-related symptoms. This study examined long-term alterations in maternal stress including self-reported psychological and biophysiological stress levels in a case-control design.

Effects of an App-Based Mindfulness Intervention during Pregnancy on the Infant's Prenatal Androgen Exposure: A Randomized Controlled Pilot Trial.

Prenatal androgen exposure modulates the development of the brain, with lasting effects on its function and behavior over the infant's life span. Environmental factors during pregnancy, in particular maternal stress, have been shown to influence the androgen load of the unborn child. We here addressed the research gap on whether a mindfulness intervention or a pregnancy education administered to pregnant women more affects the androgen exposure of the unborn child (quantified by the proxies of second-to-fourth digit length ratio (2D:4D) and anogenital distance assessed one year after delivery and at delivery, respectively).

In vitro anti-cancer activity of a polyherbal preparation, VEDICINALS®9, against A549 human lung adenocarcinoma cells.

Purpose: Non-small cell lung cancer (NSCLC) is among the leading causes of morbidity and mortality worldwide. Despite the availability of several treatment options, the five-year survival rate of NSCLC is extremely low (<20%). This underlines the necessity of more effective therapeutic alternatives.

Intranasal Route: A Nasocerebral Approach against SARS-CoV-2 in NeuroCOVID.

The nasal cavity is a prime site for viral load of SARS-CoV-2 in COVID-19, as is evident from the fact that this area has been used for sample collection for the diagnosis of COVID-19. The nasal cavity has a connection with the brain across the cribriform plate which has been reported to be a route of SARS-CoV-2 to the olfactory apparatus and the brain. Targeting the SARS-CoV-2 in the nasal cavity in patients presenting with COVID-19 and long-COVID can result in the prevention and treatment of neurological deficits and therefore needs to be prioritized as a route of potential significance.
