All-Polyethylene Tibias Equal to Metal-Backed Tibias in Primary Total Knee Arthroplasty: A Systematic Review and Meta-Analysis.

We sought to conduct a systematic review of the literature and a meta-analysis of post-operative outcomes following TKA with an all-polyethylene tibial (APT) or a metal-backed tibial component (MBT). A systematic review of the literature was conducted to identify all studies comparing APT and MBT for TKA based upon rates of complications, revisions, reoperation, and patient-reported outcomes. Data was pooled and relative risk of each outcome measure at short (< 5 year), mid (5-10 year), and long (> 10 year) follow-up was calculated.

Challenges and Progress in Neurosurgery: A Comprehensive Assessment of the Landscape in Nepal.

A large portion of the global population lacks access to essential surgical care, despite surgical conditions contributing significantly to the overall burden of disease worldwide. This burden is heaviest in developing countries like Nepal, where disparities in access to surgery for neurosurgical disorders stem from health system failures including an inadequate neurosurgical workforce, lack of requisite neurosurgical equipment, and challenges in perioperative care. By bibliometric analysis of neurosurgery-related publications in Nepal through PubMed search using the search terms "Neurosurg* AND Nepal", we have found a total of 528 articles with a notable increase in the number of such publications from 14 to 25 between 2015 and 2016, with over 300 published in 2021, 2022, and 2023.

Pleural Marginal Zone Lymphoma Masquerading as Metastatic Adenocarcinoma of the Lung.

Extranodal marginal zone lymphoma (EMZL) is a rare subtype of non-Hodgkin's lymphoma characterized by the malignant transformation of lymphoid tissue at sites affected by chronic inflammation. Pleural marginal zone lymphoma (PMZL) is an infrequent manifestation of this condition. We report a case of PMZL co-occurring with primary lung adenocarcinoma.

Anaesthesia is integral to a wide range of clinical procedures; however, there is a global challenge in the anaesthesia workforce due to several contributing factors. This study seeks to assess the knowledge and perceptions of medical students regarding anaesthesia as a specialty. Understanding these perspectives is essential to addressing the global shortage of anaesthesia professionals.

Transphyseal Curettage of Epiphyseal Brodie's Abscess: A Case Report.

Epiphyseal Brodie's abscesses represent a rare, slow-progressing form of osteomyelitis that contrasts with the more aggressive types of infection typically seen in bone. These abscesses develop from a low-grade infection and progress gradually, posing unique challenges for treatment due to their proximity to the growth plate and joint structures. While the literature on managing epiphyseal Brodie's abscesses is limited, common treatments include antibiotics and surgical drainage.

Prevention of hypertension due to long working hours and other work hazards is needed to reduce the risk of cardiovascular disease.

Hypertension is the foremost risk factor for cardiovascular disease (CVD), which is the leading cause of death globally. In some countries, such as the US, the prevalence of hypertension and working-age CVD mortality are increasing. CVD is also the most common work-related disease worldwide.

Culture-Negative Endocarditis Complicated by Cerebral Abscesses Due to Streptococcus gordonii: A Diagnostic Odyssey.

Endocarditis is a serious diagnostic entity that carries a high rate of morbidity and mortality, with complications including heart failure, septic embolization, brain abscesses, and stroke. Blood culture-negative endocarditis (BCNE) represents a particularly challenging clinical scenario where the causative organism is undetectable, either due to being difficult to culture or due to the empiric administration of antimicrobial agents. This entity generally results in delayed diagnosis and treatment of endocarditis, with a potential increase in the rate of complications.

A Model-Driven Meta-Analysis Supports the Emerging Consensus View that Inhibitory Neurons Dominate BOLD-fMRI Responses.

Functional magnetic resonance imaging (fMRI) is a pivotal tool for mapping neuronal activity in the brain. Traditionally, the observed hemodynamic changes are assumed to reflect the activity of the most common neuronal type: excitatory neurons. In contrast, recent experiments, using optogenetic techniques, suggest that the fMRI-signal instead reflects the activity of inhibitory interneurons.

Is there a ubiquitous spectrolaminar motif of local field potential power across primate neocortex?

Mendoza-Halliday, Major et al., 2024 ("") advocates a local field potential (LFP)-based approach to functional identification of cortical layers during "laminar" (simultaneous recordings from all cortical layers) multielectrode recordings in nonhuman primates (NHPs). describes a "ubiquitous spectrolaminar motif" in the primate neocortex: 1) 75-150 Hz power peaks in the supragranular layers, 2) 10-19 Hz power peaks in the infragranular layers and 3) the crossing point of their laminar power gradients identifies Layer 4 (L4).

The More You See, the More Confusion: Two Cases of Pneumonia With Confusing Imaging Findings of Adenocarcinoma.

Imaging studies are a helpful tool when facing pulmonary pathology. While a specific radiologic pattern suggests a diagnosis, a multidisciplinary approach is ideal. Pneumonia and lung adenocarcinoma (LADC) are among the leading causes of morbidity and mortality worldwide.

Collagen-targeted protein nanomicelles for the imaging of non-alcoholic steatohepatitis.

In vivo molecular imaging tools hold immense potential to drive transformative breakthroughs by enabling researchers to visualize cellular and molecular interactions in real-time and/or at high resolution. These advancements will facilitate a deeper understanding of fundamental biological processes and their dysregulation in disease states. Here, we develop and characterize a self-assembling protein nanomicelle called collagen type I binding - thermoresponsive assembled protein (Col1-TRAP) that binds tightly to type I collagen in vitro with nanomolar affinity.

Treatment of Type 2 Diabetes Mellitus in Advanced Chronic Kidney Disease for the Primary Care Physician.

Diabetes mellitus (DM) is a common cause of chronic kidney disease (CKD), leading to the need for renal replacement therapy (RRT). RRT includes hemodialysis (HD), peritoneal dialysis (PD), kidney transplantation (KT), and medical management. As CKD advances, the management of DM may change as medication clearance, effectiveness, and side effects can be altered due to decreasing renal clearance.

Classic Kaposi Sarcoma in an Immunocompetent Male From Haiti: An Unusual Epidemiological Presentation.

Kaposi sarcoma (KS) is an angioproliferative disorder caused by human herpesvirus-8 (HHV-8) infection. KS manifests as vascular and mucosal nodules and is classified into four subtypes based on epidemiology, clinical presentation, histopathology, and HHV-8/human immunodeficiency virus serology. Here, we present a unique case of classic KS in an 84-year-old immunocompetent Haitian male patient, highlighting the rarity of this variant in this population.

Gastroesophageal Junction Adenocarcinoma With Skeletal Muscle Metastases: A Case Report and Literature Review.

Esophageal and gastroesophageal junction (GEJ) malignancies are aggressive, and survival is poor once metastasis occurs. The most common sites of metastatic involvement include the liver, lymph nodes, lung, peritoneum, adrenal glands, bone, and brain, while skeletal muscle (SM) involvement is rare. We report a case of a 68-year-old female who presented with intractable emesis for one month and was found to have a primary GEJ adenocarcinoma measuring up to 6.

Interatrial Wall Abnormality is Associated with Adverse Same-Admission Outcomes Following Total Knee Arthroplasty.

Total knee arthroplasty (TKA) is the most common joint arthroplasty procedure and is shown to be a reliable and efficacious way to improve quality of life. Individuals with interatrial wall abnormalities (IAWAs), such as atrial septal defect or patent foramen ovale (PFO), are at increased baseline risk for stroke and overall lifetime morbidity. The purpose of our study was to elucidate the association between IAWAs and perioperative TKA outcomes.

The optimal timing of surgery for cervical spinal cord injuries (SCI) and its impact on neurological recovery continue to be subjects of debate. This systematic review and meta-analysis aims to consolidate and assess the existing evidence regarding the efficacy of ultra-early decompression surgery in improving clinical outcomes after cervical SCI. A search was conducted in PubMed, Embase, Cochrane, and CINAHL databases from inception until September 18, 2023, focusing on human studies.

PKCδ Protects against Lupus Autoimmunity.

Protein kinase C delta (PKCδ) has emerged as a key protective molecule against systemic lupus erythematosus (SLE or lupus), an autoimmune disease characterized by anti-double stranded (ds) DNA IgGs. Although PKCδ-deficient mice and lupus patients with mutated genes clearly demonstrate the requirement for PKCδ in preventing lupus autoimmunity, this critical tolerance mechanism remains poorly understood. We recently reported that PKCδ acts as a key regulator of B cell tolerance by selectively deleting anti-dsDNA B cells in the germinal center (GC).
