Fractional gradient optimized explainable convolutional neural network for Alzheimer's disease diagnosis.

Alzheimer's is one of the brain syndromes that steadily affects the brain memory. The early stage of Alzheimer's disease (AD) is referred to as mild cognitive impairment (MCI), and the growth of Alzheimer's is not certain in patients with MCI. The premature detection of Alzheimer's is crucial for maintaining healthy brain function and avoiding memory loss.

Severe Central Nervous System and Respiratory Depression in a Neonate Following Accidental Oral Ingestion of Brimonidine Tartrate.

Brimonidine is a third-generation alpha-2 adrenergic agonist and is classified as an ocular hypotensive agent. It is used for chronic glaucoma treatment by lowering intraocular pressure, crucial for preventing blindness. Brimonidine works by reducing aqueous humor production and increasing uveoscleral outflow.

A Rare Case of Niemann-Pick Disease Type-A.

Niemann-Pick disease is a rare lysosomal storage, autosomal recessive disorder that impairs the body's ability to metabolize fats, thus leading to accumulation within cells. It can affect various organs, most commonly the brain, liver, spleen, bone marrow and lungs. Hepatosplenomegaly, inability to thrive and varying neurological deficits are the defining features.

Formulation and evaluation of miconazole lipogel for enhanced drug permeation.

Efficacy and Safety of Intranasal Fentanyl in Pediatric Emergencies: A Systematic Review and Meta-analysis.

Background: Intranasal fentanyl (INF) has gained popularity in pediatric emergency departments (EDs) as an effective alternative to intravenous morphine for treating acute moderate to severe pain. Intranasal fentanyl eliminates the need for invasive access, making it advantageous for patients with minor injuries. Our study aims to provide a comprehensive evaluation of the available evidence regarding the effectiveness and safety of INF administration in pediatric emergency wards, particularly compared with other treatment options described in the literature.

Development of palliative care clinical practice guidelines and referral care pathways for primary care practitioners in Pakistan.

Background: Despite a large burden of life-limitingillness, there exists a dearth of services of palliative care in Pakistan. International guidelines have questionable applicability in Pakistan due to the socioeconomic differences. We generated a protocol describing the process of developing comprehensive palliative care guidelines and palliative care referral pathways for primary care practitioners to adopt in Pakistan.

Navigating the tumor microenvironment: mesenchymal stem cell-mediated delivery of anticancer agents.

Scientific knowledge of cancer has advanced greatly throughout the years, with most recent studies findings includes many hallmarks that capture disease's multifaceted character. One of the novel approach utilised for the delivery of anti-cancer agents includes mesenchymal stem cell mediated drug delivery. Mesenchymal stem cells (MSCs) are non-haematopoietic progenitor cells that may be extracted from bone marrow, tooth pulp, adipose tissue and placenta/umbilical cord blood dealing with adult stem cells.

Advanced polymers and recent advancements on gastroretentive drug delivery system; a comprehensive review.

Oral route of drug administration is typically the initial option for drug administration because it is both practical and affordable. However, major drawback of this route includes the release of drug at a specified place thus reduces the bioavailability. This could be overcome by utilising the gastroretentive drug delivery system (GRRDS).

Non-compliance of Spectacle Wear in School-Going Children With Refractive Errors.

Background Uncorrected refractive errors are the most common cause of avoidable visual impairment in children worldwide. The school screening of refractive errors is one of the most important initiatives outlined in WHO Vision 2020 targets for control of avoidable visual impairment in children. However, the benefit depends on the compliance of the spectacle worn by children.

Vesicular approach of cubosomes, its components, preparation techniques, evaluation and their appraisal for targeting cancer cells.

Cancer has been characterized by abnormal and uncontrolled proliferation of cells. Majority of drugs given through chemotherapy produce unwanted and adverse effects of chemotherapeutic agents to the other healthy cells and tissues of body. Various nanocarriers have now been considered for treatment of cancer.

Formulation, Characterization, and Evaluation of β-Cyclodextrin Functionalized Hypericin Loaded Nanocarriers.

St. John's wort in western Europe has been extensively utilized for the treatment of mild to moderate depression. Hypericin, a red pigment, is found to be responsible for its antidepressant activity.

Solid lipid nanoparticles: a versatile approach for controlled release and targeted drug delivery.

Solid Lipid Nanoparticles (SLN), the first type of lipid-based solid carrier systems in the nanometer range, were introduced as a replacement for liposomes. SLN are aqueous colloidal dispersions with solid biodegradable lipids as their matrix. SLN is produced using processes like solvent diffusion method and high-pressure homogenization, among others.

Confronted With Death: Factors Affecting End of Life Decisions in the Intensive Care Unit.

To determine how often care is limited at the end of life and the factors that are associated with this decision, we reviewed the medical records of all patients that passed away in the intensive care units (ICU) of Aga Khan University.

Arterio-Ureteral Fistula: A Rare Elusive Cause of Significant Hematuria.

Arterioureteral fistula (AUF) is a direct communication between the ureter and an artery and is a rare cause of catastrophic, life-threatening haematuria. Fistulation may occur between the ureter and the abdominal aorta, common iliac, external and internal iliac, and inferior mesenteric arteries, and is typically observed in patients with a prior history of pelvic radiotherapy, oncological pelvic surgeries, aortoiliac vascular procedures, and pelvic exenteration. There is also an increased frequency of cases amongst patients who have undergone urological diversion surgeries and in those with chronic indwelling ureteric stents requiring repeated exchange.
