Nasal microbiota transplantation: a gateway to novel treatments.

Two recent studies have highlighted the potential of nasal microbiota transplantation (NMT) to treat chronic rhinosinusitis (CRS). Here we evaluate these findings and propose that lessons from fecal microbiota transplantation (FMT) could guide NMT development, with possible implications for combating antimicrobial resistance in respiratory infections.

Reliability of cushion construction for a low-cost pressure-reducing wheelchair cushion for less-resourced settings.

In less-resourced settings, 80% of people with spinal cord injuries die from pressure ulcer complications within two years. Appropriately constructed wheelchair cushions are effective in reducing incidence and severity of pressure ulcers. The Tuball is an inexpensive wheelchair cushion designed for users in less-resourced settings, which can be reproduced by local clinicians using locally sourced materials.

Prolonged hospitalization signature and early antibiotic effects on the nasopharyngeal resistome in preterm infants.

Respiratory pathogens, commonly colonizing nasopharynx, are among the leading causes of death due to antimicrobial resistance. Yet, antibiotic resistance determinants within nasopharyngeal microbial communities remain poorly understood. In this prospective cohort study, we investigate the nasopharynx resistome development in preterm infants, assess early antibiotic impact on its trajectory, and explore its association with clinical covariates using shotgun metagenomics.

Exploring ex vivo biofilm dynamics: consequences of low ampicillin concentrations on the human oral microbiome.

Prolonged exposure to antibiotics at low concentration can promote processes associated with bacterial biofilm formation, virulence and antibiotic resistance. This can be of high relevance in microbial communities like the oral microbiome, where commensals and pathogens share a common habitat and where the total abundance of antibiotic resistance genes surpasses the abundance in the gut. Here, we used an ex vivo model of human oral biofilms to investigate the impact of ampicillin on biofilm viability.

Overexpression of human alpha-Synuclein leads to dysregulated microbiome/metabolites with ageing in a rat model of Parkinson disease.

Background: Braak's hypothesis states that sporadic Parkinson's disease (PD) follows a specific progression of pathology from the peripheral to the central nervous system, and this progression can be monitored by detecting the accumulation of alpha-Synuclein (α-Syn) protein. Consequently, there is growing interest in understanding how the gut (commensal) microbiome can regulate α-Syn accumulation, as this could potentially lead to PD.

Methods: We used 16S rRNA and shotgun sequencing to characterise microbial diversity.

Management and Clinical Outcomes of 37 Patients with Necrotizing Otitis Externa: Retrospective Review of a Standardized 6-Week Treatment Pathway.

Background: Necrotizing otitis externa is an invasive infection, affecting older patients, with significant associated morbidity. Despite this, there are no randomized controlled trials that address management, and therefore, treatment approaches may vary considerably. We describe the management and outcomes of 37 patients managed using a multidisciplinary treatment pathway for necrotizing otitis externa over a 5-year period.

When feelings hurt: Learning how to talk with families about the role of emotions in physical symptoms.

Emotions are at the core of all human experiences, but talking about emotions is challenging, particularly in the context of medical encounters focused on somatic symptoms. Transparent, normalizing, and validating communication about the mind-body connection opens the door for respectful, open dialogue between the family and members of the care team, acknowledging the lived experience that is brought to the table in understanding the problem and co-creating a solution.

Microbial DNA extraction of high-host content and low biomass samples: Optimized protocol for nasopharynx metagenomic studies.

Introduction: Low microbial biomass and high human DNA content in nasopharyngeal aspirate samples hinder comprehensive characterization of microbiota and resistome. We obtained samples from premature infants, a group with increased risk of developing respiratory disorders and infections, and consequently frequent exposure to antibiotics. Our aim was to devise an optimal protocol for handling nasopharyngeal aspirate samples from premature infants, focusing on host DNA depletion and microbiome and resistome characterization.

Differential response to prolonged amoxicillin treatment: long-term resilience of the microbiome versus long-lasting perturbations in the gut resistome.

The collateral impact of antibiotics on the microbiome has attained increasing attention. However, the ecological consequences of long-term antibiotic exposure on the gut microbiome, including antibiotic resistance, are still limited. Here, we investigated long-term exposure effects to amoxicillin on the human gut microbiome and resistome.

Attachment and Clinical Outcomes Among Treatment-Seeking Adults With Persistent Symptoms After Mild Traumatic Brain Injury.

Objective: Interpersonal attachment influences the development and course of disease. Overreliance on insecure attachment strategies may increase risk for poor disease outcomes. This study aimed to investigate largely unexplored relationships between attachment strategies and clinical outcomes among adults with persistent symptoms after mild traumatic brain injury (mTBI).

Intrathecal daptomycin use in a challenging case of ventriculitis.

Treatment of ventriculitis caused by enterococci can be challenging, and antibiotic options are limited. We describe a case of device-related ventriculitis caused by vancomycin-resistant , refractory to initial antibiotics. Our management approach included intrathecal daptomycin.

An algorithmic approach to identifying the aetiology of acute encephalitis syndrome in India: results of a 4-year enhanced surveillance study.

Background: Annual outbreaks of acute encephalitis syndrome pose a major health burden in India. Although Japanese encephalitis virus (JEV) accounts for around 15% of reported cases, the aetiology of most cases remains unknown. We aimed to establish an enhanced surveillance network and to use a standardised diagnostic algorithm to conduct a systematic evaluation of acute encephalitis syndrome in India.

Somatization in Adolescents With Persistent Symptoms After Concussion: A Retrospective Chart Review.

Objective: After concussion, approximately 30% of adolescents experience symptoms that persist beyond 1 month postinjury. For some, these symptoms affect functioning, development, and quality of life. Somatization, where psychological distress contributes to physical symptoms, may contribute to persistent symptoms after concussion in some adolescents.

Pediatric Avoidant-Restrictive Food Intake Disorder and gastrointestinal-related Somatic Symptom Disorders: Overlap in clinical presentation.

Certain presentations of Avoidant/Restrictive Food Intake Disorder (ARFID) and Somatic Symptom and Related Disorders (SSRDs) have conceptual overlap, namely, distress and impairment related to a physical symptom. This study compared characteristics of pediatric patients diagnosed with ARFID to those with gastrointestinal (GI)-related SSRD. A 5-year retrospective chart review at a tertiary care pediatric hospital comparing assessment data of patients with a diagnosis of ARFID ( = 62; 69% girls, = 14.

Proteinuric chronic kidney disease is associated with altered red blood cell lifespan, deformability and metabolism.

Anemia is a common complication of chronic kidney disease, affecting the quality of life of patients. Among various factors, such as iron and erythropoietin deficiency, reduced red blood cell (RBC) lifespan has been implicated in the pathogenesis of anemia. However, mechanistic data on in vivo RBC dysfunction in kidney disease are lacking.

India's need for long-term solutions to COVID-19-like pandemics: A policy paper by Organized Medicine Academic Guild.

The entire world seems to have responded to COVID-19 pandemic in a knee-jerk manner with a short mindset without building on the existing strengths of public health infrastructure. National governments cannot be blamed for this as we are dealing with a crisis that comes once in a lifetime. Realising this, the Organized Medicine Academic Guild (OMAG) an association of major health associations in this country has suggested measures for long-term solutions to COVID-19-like pandemics in the form of a policy paper by OMAG.

The utility of universal screening for somatization in a pediatric emergency department: A prospective evaluation.

Objective: To evaluate clinical utility and feasibility of universal somatization screening in the pediatric emergency department (ED) using a standardized approach of (1) identifying potential somatizing symptoms within the ED, (2) introducing these patients and their caregivers to the concept of the 'mind-body connection', (3) corroborating the likelihood of a somatization diagnosis via brief psychiatric assessment, and (4) inviting families to a psychoeducational follow-up session.

Methods: We conducted a cross-sectional study to carry out this approach with families visiting a pediatric ED. Our primary outcome of screening utility was measured as the proportion of youth who screened positive for somatization by the ED clinician.

The Barts Health NHS Trust COVID-19 cohort: characteristics, outcomes and risk scoring of patients in East London.

Barts Health National Health Service Trust (BHNHST) serves a diverse population of 2.5 million people in London, UK. We undertook a health services assessment of factors used to evaluate the risk of severe acute respiratory coronavirus 2 (SARS-CoV-2) infection.

ResistoXplorer: a web-based tool for visual, statistical and exploratory data analysis of resistome data.

The study of resistomes using whole metagenomic sequencing enables high-throughput identification of resistance genes in complex microbial communities, such as the human microbiome. Over recent years, sophisticated and diverse pipelines have been established to facilitate raw data processing and annotation. Despite the progress, there are no easy-to-use tools for comprehensive visual, statistical and functional analysis of resistome data.

The Stanford Integrated Psychosocial Assessment for Transplant Is Associated With Outcomes Before and After Liver Transplantation.

The Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) is a standardized psychosocial evaluation tool used in liver transplantation (LT) evaluation. We assessed the impact of the SIPAT score and subdomains on transplant waitlisting decisions and post-LT outcomes including immunosuppression (IS) nonadherence, biopsy-proven rejection, andmortality/graft failure. We conducted a single-center observational cohort study of 1430 patients evaluated for LT.

DJ-1 (Park7) affects the gut microbiome, metabolites and the development of innate lymphoid cells (ILCs).

The proper communication between gut and brain is pivotal for the maintenance of health and, dysregulation of the gut-brain axis can lead to several clinical disorders. In Parkinson's disease (PD) 85% of all patients experienced constipation many years before showing any signs of motor phenotypes. For differential diagnosis and preventive treatment, there is an urgent need for the identification of biomarkers indicating early disease stages long before the disease phenotype manifests.

Case Report: Visceral Leishmaniasis Falsely Diagnosed as Q Fever.

Visceral leishmaniasis (VL) is a systemic infection caused by the protozoal parasite , spread via the bloodstream to the reticuloendothelial system, through the bite of the sand fly. It is endemic in parts of Africa, South America, Asia, and Europe, including the Mediterranean. Here, we describe a case of VL that was initially diagnosed as Q fever based on positive serology and showed a partial response to doxycycline treatment.

Role of laccase gene in wheat NILs differing at QTL-Fhb1 for resistance against Fusarium head blight.

Fusarium head blight (FHB), caused mainly by Fusarium graminearum (Fg), is one of the most severe diseases of wheat. It affects grain yield and quality due to mycotoxin contamination, which is harmful for both human and livestock consumption. Cell wall lignification, following pathogen invasion, is one of the innate defense responses.
