Tiny But Mighty, An Exploration Of Microbes And Plants As Sources Of Small Novel Bioactive Compounds Against Invasive Mycoses., Hannah Mai Peacock, James Anthony O'Connor

SURE Journal: Science Undergraduate Research Experience Journal

Despite the high mortality rate involved with invasive cerebral mycoses, there is a relative lack of research available around antifungals capable of crossing the blood brain barrier.

In this study the metabolites of four plants (Crocus vernus, Miniature Narcissus (daffodil), Osmanthus delavayi and Taraxacum officinale (common dandelion)) and two bacteria (Lacticaseibacillus paracasei and Staphylococcus epidermidis) were extracted and assayed for antifungal activity against Candida albicans and Saccharomyces cerevisiae. Thin layer chromatography and bioautography were then employed to assess the activity of the constituent components of sources showing antifungal activity.

We report a case of a male in his thirties who presented with rapidly progressive encephalopathy, mediastinal abscess, and multiple ring-enhancing lesions throughout the brain. Extensive evaluation revealed Streptococcus intermedius septic emboli to the brain from dental sources via a right-to-left anatomic shunt. The patient completed an 11-week course of IV antibiotic therapy after which he made a near complete recovery. We provide a comprehensive review of the literature with Streptococcus intermedius CNS septic emboli and source of infection.

Severe Thrombocytopenia In Infective Endocarditis, Mayuri Patel, Biplov Adhikari, Amrit Devkota, Mahsa Mohebtash

Journal of Community Hospital Internal Medicine Perspectives

Thrombocytopenia can be seen in about 20-25% of patients with bacterial infective endocarditis (IE). Platelets have a major role in the pathogenesis of endocarditis, and they are also sensitive monitors of systemic host response to bacteremia. Thrombocytopenia on presentation of patients with IE identifies higher risk groups and carries higher mortality risk. The presence of thrombocytopenia is an independent prognosticator of poor outcomes in IE. We present a case of a 40-year-old male with the history of injection drug use who was diagnosed with IE and was found to have severe thrombocytopenia on admission was treated with intravenous antibiotics, which …

Diagnosis And Management Of A Patient With Methicillin-Resistant Staphylococcus Aureus Conjunctivitis, Michael Chocky Od

Optometric Clinical Practice

Background : Methicillin-resistant Staphylococcus aureus (MRSA) infections are becoming more common. These infections can cause various ocular conditions including conjunctivitis. Conjunctival cultures are an important tool to assist with proper diagnosis and treatment of these infections. Case Report : A 61-year-old African American male presented with the complaint of redness and drainage from his eyes. With the assistance of conjunctival cultures, he was diagnosed with MRSA conjunctivitis. Treatment with vancomycin ultimately led to resolution of the condition. Conclusion : MRSA conjunctivitis should always be considered when a conjunctivitis is not responding to empirical therapy. Eye care professionals should be aware …

Rhino-Cerebral Aspergillosis In An Immunocompetent Patient, Jisun Won, Carolina Severiche Mena, Joseph Glowacki, Dimple Patel

Journal of Community Hospital Internal Medicine Perspectives

Rhino-cerebral aspergillosis is a rare phenomenon describing a contiguous spread of Aspergillus species from the paranasal sinuses to the intracranial space. In this case report, we describe a case of invasive rhino-cerebral aspergillosis arising in the setting of prolonged intranasal steroid use in an 81-year-old patient with chronic sinusitis. This case report emphasizes the importance of recognizing steroid use as a risk factor for invasive aspergillosis in otherwise immunocompetent individuals.

Challenges In Diagnosing Staphylococcal Scalded Skin Syndrome In Children With Kwashiorkor: A Case Report, Christie Hamdali, Sondang Sirait, Adria Rusvita, Bawono Bhakti

Journal of General - Procedural Dermatology & Venereology Indonesia

Staphylococcal scalded skin syndrome (SSSS) is a type of exfoliating skin disease with high incidence in children. This condition can cause serious morbidity and even mortality with certain comorbid diseases such as malnutrition. Malnutrition could mask the diagnosis of SSSS because of its similarity to numerous differential diagnoses. Accuracy of clinical diagnosis is then essential to determine the proper initial management. This case report presents a 6-month-old male baby with staphylococcal scalded skin syndrome and kwashiorkor. The patient presented with complaints of multiple erythematous plaques and widespread vesicular lesions that subsequently ruptured, resulting in erosions. Physical examination revealed edema, coarse …

A Review On Antibiotic Resistance And The Use Of Medicinal Plants In The Management Of Uropathogenic Bacteria, Hubza Ruatt Khan, Mehvish Javeed, Iqra Batool, Rabeea Anwar, Asma Ashraf, Sara Janiad

Journal of Bioresource Management

UTIs are the most prevalent infections and are caused by uropathogenicmicrobes such as Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus, and Enterococcus spp. Antibiotic resistance has hampered the management of UTIs over the years, with direct repercussions on the treatment cost, the infection severity, and the duration of hospitalization. This review discussed the route of infections, risk factors connected to UTIs, antibiotic resistance issues as well as an alternative therapy to overcome the problem of antibiotic resistance. The medicinal plants which have been utilized for thousands of years to cure a variety of ailmentsrepresent a significant antibiotic …

Identification Of Molecular Markers Associated With Copd In Non-Smokers And Smokers: A Bioinformatics Analysis, Agede O. Ayodele, Isa M. Wasagu, Ademola E. Fawibe, Alakija K. Salami

The University of Louisville Journal of Respiratory Infections

Background

Even though the proportional burden of COPD among never-smokers is significant in both developing and developed nations, accounting for around 30% of all COPD in the community, there is little awareness of the prevalence of COPD in this population. Understanding the molecular processes that underlie COPD in nonsmokers is essential.

Methods

Dataset (GSE146560) was acquired from the Gene Expression Omnibus (GEO). The limma and clusterProfiler software tools were used to identify differentially expressed genes (DEGs) and conduct a functional enrichment analysis respectively.

Results

In all, 10,583 DEGs were found, of which 1,065 were up-regulated and 9,518 were down-regulated. The …

Implementing Auc Monitoring In A Pharmacist-Managed Vancomycin Dosing Protocol: A Retrospective Cohort Study, Brandon L S Robinson, Blake Bennie, Mahmoud Nasiri, Kieu Nguyen, Reba Forbess, Mallory Gessner-Wharton, Cassie Robertson

HCA Healthcare Journal of Medicine

Background

Consensus guidelines on the therapeutic drug monitoring of vancomycin published in 2020 recognize that using the calculated area-under-the-curve (AUC) to guide dosing maximizes clinical efficacy and minimizes risk when compared to traditional trough-based dosing. The purpose of this study was to determine whether AUC monitoring results in reduced acute kidney injury (AKI) rates in adult patients receiving vancomycin for all indications.

Methods

In this study, patients 18 years or older who received pharmacist-managed vancomycin therapy were selected using pharmacy surveillance software from 2 timeframes. Patients were excluded if they received less than 48 hours of therapy or had unstable …

Performance Of A Sars-Cov-2 Rt-Pcr Assay With Non-Traditional Specimen Types, Subathra Marimuthu, Holly Aliesky, Heather Ness, Daniya Sheikh, Sathya Rashmit, Dawn Balcom, Leslie A. Wolf

The University of Louisville Journal of Respiratory Infections

During the first two years of the coronavirus disease 2019 (COVID-19) pandemic, nasopharyngeal (NP) specimens were the gold standard for clinical diagnostic testing. As information about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the pandemic continued to be shared, it was clear that the virus could be detected in other specimen types during an active infection. The University of Louisville Infectious Diseases Laboratory accepted non-traditional specimen types, most without a paired, positive NP result, for research purposes only to support local epidemiology efforts. A real-time reverse transcription-polymerase chain reaction (RT-PCR) assay originally validated for NP specimens was used …
