Background: Neuronal ceroid lipofuscinoses (NCLs) are progressive, autosomal recessive lysosomal storage disorders primarily affecting children, marked by seizures, cognitive decline, motor regression, and visual impairment. Limited genetic data exist for South Asian populations, with most studies relying on enzymatic assays or electron microscopy. This study explores the genetic spectrum of NCL and genotype-phenotype correlations in a cohort from South India.

Ayurveda has unique and relevant methods in nosology, symptomatology, and drug selection. These methods need a novel and effective way of presentation for convenient comprehension and implementation. 'Clinical algorithms' is one such way, wherein a large amount of data is simplified, conceptual intricacies abstracted, and clinical application made easier.

Introduction: This work focuses on the Dengue-viremia ABC (Atangana-Baleanu Caputo) fractional-order differential equations, accounting for both symptomatic and asymptomatic infected cases. Symptomatic cases are characterized by higher viremia levels, whereas asymptomatic cases exhibit lower viremia levels. The fractional-order model highlights memory effects and other advantages over traditional models, offering a more comprehensive representation of dengue dynamics.

Background Diabetic foot ulcers (DFUs) are common complications in diabetes patients, often leading to sepsis and leg amputation. Methicillin-resistant Staphylococcus aureus (MRSA) infections in DFUs pose challenges due to methicillin resistance with and genes. This study aims to assess the prevalence of MRSA in clinical isolates from DFUs, analyze the antibiogram of MRSA isolates, and detect the presence of the and genes among MRSA isolates.

Article Synopsis
  • Lumbar spine surgeries often cause significant post-op pain, and two regional anesthesia methods, Erector Spinae Plane Block (ESPB) and Thoracolumbar Interfascial Plane Block (TLIPB), are being compared for their effectiveness in pain management.
  • In a study with 60 patients, results showed that patients receiving the ESPB technique consumed more opioids and experienced higher pain scores compared to those receiving TLIPB, which also provided a quicker analgesic effect.
  • Overall, while both techniques are effective, TLIPB may reduce opioid use and is quicker to provide relief, but ESPB may last longer in terms of pain management, calling for further research to confirm these findings.

Cancer has arisen from both genetic mutations and epigenetic changes, making epigenetics a crucial area of research for innovative cancer prevention and treatment strategies. This dual perspective has propelled epigenetics into the forefront of cancer research. This review highlights the important roles of DNA methylation, histone modifications and non-coding RNAs (ncRNAs), particularly microRNAs (miRNAs) and long non-coding RNAs, which are key regulators of cancer-related gene expression.

Unlabelled: , a zoonotic pathogen causing enteric diseases in different animals and humans. A comprehensive study on the presence of toxin genes and antimicrobial resistance genes based on genome data of in animals is scanty. In the present study, a total of 15 isolates were recovered from dogs and isolates with toxin genes (D1, CD15 and CD26) along with two other non-toxigenic strains (CD28, CD32) were used for whole genome sequencing and comparative genomics.

Introduction: Anti-inflammatory and anti-fibrotic properties maximize the therapeutic potential of bone marrow aspiration concentrate (BMAC) in osteoarthritis (OA) knee. There is a lack of studies to standardize the treatment procedure to make the studies done across various centers comparable to understand the lacunae better and develop further the deficiency in our understanding of BMAC for OA knee. We aimed to assess the degree of pain relief, functional outcome, and cartilage thickness with different doses of BMAC in primary OA knee.

Introduction: Osteoarthritis (OA) is a degenerative joint disease characterized by cartilage degradation, bone remodeling, and pain. Recent evidence suggests that Vitamin D insufficiency, alterations in parathyroid hormone (PTH) levels, and dyslipidemia may play roles in the pathophysiology of OA, affecting calcium homeostasis and bone health. We investigated the association between Vitamin D, PTH levels, lipid profile, and calcium homeostasis in OA patients.

Article Synopsis
  • - The study focuses on evaluating how oxygen extraction fraction (OEF) and deoxyhemoglobin (DoHb) levels indicate variations in brain metabolism among patients with different stages of dementia, using advanced MRI techniques.
  • - Researchers employed a multi-echo gradient-echo (mGRE) MRI scan on a powerful 3.0 Tesla scanner to perform a detailed analysis, requiring simplifications of the qBOLD model to enhance data relevance.
  • - The investigation utilized existing MRI data from Alzheimer’s, mild cognitive impairment, and healthy patients to assess brain metabolism, validating its results through statistical methods and clustering techniques.

Background and objective Bloodstream infections (BSIs) due to multidrug-resistant Gram-negative bacteria (MDR-GNB) pose a significant global health threat amid rising antimicrobial resistance (AMR). This study aimed to investigate the efficacy of ceftazidime-avibactam (CZA) as a therapeutic option for these infections, addressing the urgent need for novel treatments. Materials and methods This study was conducted over one year in the Department of Microbiology, JSS Medical College and Hospital, Mysuru, India, and employed a laboratory-based prospective design.

We report an extremely rare case of gooseneck snare-assisted retrieval of an embolized coronary guidewire from the aortic arch in an elderly male scheduled for a transradial coronary angiogram for unstable angina. In this case, the proximal end of the embolized coronary guidewire could not be retrieved from the brachial artery nor the roomy aortic root using a flower petal snare. The key takeaway from this case is that an embolized coronary guidewire can be successfully retrieved with a gooseneck snare from its proximal end in a moderately spacious area like the aortic arch.

Background: The neurovascular conflict (NVC) causing hemifacial spasm (HFS) can also cause compression of ventrolateral medulla (VLM) which contains the central sympathetic neurons. VLM compression has been associated with hypertension. Whether the VLM compression in HFS patients is associated with hypertension is not clear.

We report an extremely rare case of spontaneous closure of grade 1 coronary perforation by the snowplow phenomenon during the revascularization of a subtotal occlusion in the left anterior descending coronary artery. Coronary artery perforation is usually a nightmare during coronary intervention in the cardiac catheterization laboratory. While large coronary perforation requires the deployment of a covered stent, small perforations require heparin reversal, prolonged balloon inflation, deployment of small coils, or gel foam closure.

Introduction and methods Blood culturing has become one of the backbone investigations for septicemia, fever of unknown origin, etc. This study was conducted to test the effect of multimodal interventions on the practical skills of healthcare workers (HCWs), raise awareness regarding the importance of aseptic blood culture collection practices, and increase compliance with the specific steps to be followed. Hence, this current interventional study was aimed at comparing the rate of isolation of contaminants grown among the blood culture specimens, assessing the knowledge, attitude, and practice (KAP) of HCWs collecting the blood culture specimen on various aspects of sample collection, educating the nursing staff regarding blood sample collection using a structured, pre-formed checklist, and emphasizing best practices for blood culture collection.

"Confessions of an Ayurveda Professor", by Kishor Patwardhan, published in IJME, has set the stage for heated discussions within and outside the medical circles. It uses primitive philosophical criteria to argue that Ayurvedic principles relating to anatomy and physiology are obsolete, and that they need to be removed from the syllabus. As Ayurveda students, we explore the counterview to this, pointing out the fallacies behind each point raised, and suggest solutions that we find suitable for effective, competency-based Ayurveda education.
