As opportunities for cadaveric study dwindle, we propose a simplified perfusion model for formalin fixed cadavers that allow for endoscopic neuroanatomical study and procedural practice. This model is easily accessible, cost effective, and valuable in medical training. Materials and Methods: Cadavers were fixed through accepted methods that included formalin injection into the cranial vault. The perfusion system was set up using a series of catheters, tubing, and pressurized saline bag that forced saline into the various neuroanatomical spaces chosen for study. Results: A neuroendoscope was subsequently introduced to explore and identify relevant neuroanatomical structures as well as to perform a 3rd ventriculostomy and filum sectioning. Conclusion: Using formalin fixed cadavers for neuroendoscopic studies and procedural practice is a cost effective, multipurpose tool that can provide...

When the status of nerves is not accurately assessed, treatment may be delayed or overlooked and can result in lasting functional deficits. As our understanding of nerve repair and generation evolves, so will tools for evaluating both the functional and morphological status of peripheral nerves. Objective There is currently no single article which provides a detailed, comprehensive view of the literature comparing the clinical utility of various assessment modalities. Furthermore, there is no consensus on the optimal assessment algorithm for peripheral nerve injuries. Methods We performed a literature review using a comprehensive combination of keywords and search algorithm. The search was focused on clinical data regarding the assessment of peripheral nerves Results: This review may help to determine the appropriate tools that are currently available for...

The typical age of presentation is bimodal, with peak incidence rates in children at age 5 to 14 years and in adults at age 50 to 74 years. The usual clinical manifestations are related to endocrine deficiencies due to mass effect along with visual impairment and increased intracranial pressure. If a tumor is favorably localized, the treatment of choice is complete resection. OBSERVATIONS The authors presented a unique case of a 61-year-old man with a suspicious cystic lesion in the right orbital roof that was causing right-sided headaches with pressure and pain in the right eye. Both computed tomography and magnetic resonance imaging were used for further evaluation and showed a suspicious lytic bone lesion that had an epicenter within the orbital rim, which was highly suggestive of a tumor of interosseous origin. After re...

The primary aim of this study was to determine whether HAP rates fluctuate during the year at the University Medical Center (UMC) in Lubbock, Texas. An internal data source maintained by UMC’s Infection Prevention & Control Office called MedMined that builds an algorithm using nosocomial infection markers (NIMs) was used to track HAP rates. The NIMs are microbiology results from various sample sources, including urine, stool, wound, respiratory secretions, and other, that provide a better understanding of a patient’s infection risk and status. MedMined respiratory NIMs data on quarterly scorecards from January 2015 to March 2020 were evaluated using one-way analysis of variance (ANOVA) and subsequently stratified to the departmental level (e.g., MICU, SICU, etc.) followed...

Diabetes potentiates diastolic and systolic cardiac failure following the myocardial infarction that produces the cardiac muscle-specific microvascular complication, clinically termed as diabetic cardiomyopathy. Elevated susceptibility of diabetic cardiomyopathy is primarily caused by the generation of free radicals in the hyperglycemic milieu, compromising the myocardial contractility and normal cardiac functions with increasing redox insult, impaired mitochondria, damaged organelles, apoptosis, and cardiomyocytes fibrosis. Autophagy is essentially involved in the recycling/clearing the damaged organelles, cytoplasmic contents, and aggregates, which are frequently produced in cardiomyocytes. Although autophagy plays a vital role in maintaining the cellular homeostasis in diligent cardiac tissues, this process is frequently impaired in the diabetic heart. Given its clinical significance, accumulating evidence largely showed the functional aspects of autophagy in diabetic cardiomyopathy, elucidating its intricate protective and pathogenic outcomes. However, etiology and molecular readouts of these contrary autophagy activities in diabetic cardiomyopathy are not yet comprehensively assessed and translated. In this review, we attempted to assess the role of autophagy and its adaptations in the diabetic heart. To delineate the molecular consequences of these events, we provided detailed insights into the autophagy regulation pieces of machinery including the mTOR/AMPK, TFEB/ZNSCAN3, FOXOs, SIRTs, PINK1/Parkin, Nrf2, miRNAs, and others in the diabetic cardiomyopathy. Given the clinical significance of autophagy in the diabetic heart, we further discussed the potential pharmacotherapeutic strategies towards targeting autophagy. Taken together, the present report meticulously assessed autophagy, its adaptations, and molecular regulations in diabetic cardiomyopathy and reviewed the current autophagy-targeting strategies.

While the virus does not discriminate, the elderly and those with comorbidities, including hypertension severe obesity, diabetes mellitus, coronary disease, pneumonia and dementia, are at a greater risk for adverse outcomes due to COVID-19. While many people navigate their new normal, the question of what the long-lasting effects of the pandemic may be, lingers. To investigate how vulnerable populations are affected by the pandemic, we focused on Alzheimer’s disease, a vector to understanding how the virus has impacted AD progression and risk via aging. By assessing the effect of COVID-19 on AD patients, we explore genetics, metabolism, and lifestyle factors in both COVID-19 and Alzheimer’s disease that can work synergistically to precipitate adverse outcomes. This article also discusses how age-related conditions and/or age-related comorbidities susceptible to COVID-19. We also discuss possible healthy lifestyle factors reduce and/or combat COVID-19 now and in the future.

Chronic hyperglycemia can induce several vascular complications that were referred to be the major cause of morbidity and mortality in DM. Although several therapeutic targets have been identified and accessed clinically, the imminent risk of DM and its prevalence are still ascending. Substantial pieces of evidence revealed that histone deacetylase (HDAC) isoforms can regulate various molecular activities in DM via epigenetic and post-translational regulation of several transcription factors. To date, 18 HDAC isoforms have been identified in mammals that were categorized into four different classes. Classes I, II, and IV are regarded as classical HDACs, which operate through a Zn-based mechanism. In contrast, class III HDACs or Sirtuins depend on nicotinamide adenine dinucleotide (NAD+) for their molecular activity. Functionally, mos...

It presents a particularly complex challenge in diagnosis and management in the context of burn trauma. We followed five burn patients who developed ACPO that did not respond to conservative treatments. These patients ultimately required surgical intervention to resolve their ACPO. Through our study, we propose that traditional management may not be successful in fully treating ACPO in burn patients without recurrence and that complete resolution necessitates a more aggressive management course, often in the form of surgical intervention. Methods We studied the clinical course of all burn patients who developed ACPO in the past 2 years at our burn center. Using Electronic Health Records, we collected patient demographic data, percent total burn surface area (%TBSA), hospital length of stay, cecal diameter, bowel regime...

Despite the many years of research, AD still harbors many secrets. As more of the world's population grows older, researchers are striving to find greater information on disease progression and pathogenesis. Identifying and treating the markers of this disease, or better yet, preventing it all together, are the hopes of those investing in this field of study. Several years of research revealed that synaptic pathology and mitochondrial oxidative damage are early events in disease progression. Loss of synapses and synaptic damage are the best correlates of cognitive deficits found in AD patients. As the disease progresses, there are significant changes at the synapse. These changes can both shed greater light onto the progression of the disease and serve as markers and therapeutic targets. This article addresses the mechanisms of synaptic action, mitochondrial regulation/dysregulation, resulting synaptic changes caused by amyloid beta and phosphorylated tau in AD progression. This article also highlights recent developments of risk factors, genetics and ApoE4 involvement, factors related to synaptic damage and loss, mislocalization of amyloid beta and phosphorylated tau, mitophagy, microglial activation and synapse-based therapies in AD. Furthermore, impairments in LTD and reactivation of microglia are discussed.

It is caused by severe acute respiratory syndrome-corona virus-2 (SARS-CoV-2). To date, the USA, Italy, Spain, France, Russia, and the UK have been hit the hardest by the virus. However, death counts are still rising. Some nations have managed to "flatten" the death rate via protective measures such physical distancing, quarantine measures, and therapeutic management. The structure of the SARS-CoV-2 virus comprises of S proteins, M proteins, E proteins, hemagglutinin esterases, nucleocapsid proteins, and a 30kb RNA genome. Viral proteases cleave these polyproteins and RNA-dependent polymerases replicate the genome. Currently, there are no effective therapies against this new disease. Numerous investigators are developing novel protease inhibitors, some of which have made it into clinical trials. Researchers are also attempting to develop a vaccine. In this review paper, we discuss the latest therapeutic developments against COVID-19.

It is also a coronavirus that shares similarities to SARS-CoV and MERS-CoV with respect to pathophysiology, transmission, and affected populations. A review of the literature was conducted to explain possible underlying reasons for the difference in coronaviruses’ effects on certain demographics with a focus on gender/sex and race/ethnicity. Both male and female genders vary in their biological makeup, including immunity, hormones, and physiological components, such as angiotensin-converting enzyme 2 (ACE2). These variations seem to give moderate support to the data that demonstrate a higher mortality rate of COVID-19 in males. Yet, these factors must be investigated further since the current studies are limited in scope and sample size as the COVID-19 pandemic continues to evolve. Information involving COVID-19 racial and ethnic data currently is li...

Currently, over 2000 mammalian miRNAs have been reported to regulate these biological processes. A subset of microRNAs was found to be localized to human mitochondria (mitomiRs). Through years of research, over 400 mitomiRs have been shown to modulate the translational activity of the mitochondrial genome. While miRNAs have been studied for years, the function of mitomiRs and their role in neurodegenerative pathologies is not known. The purpose of our article is to highlight recent findings that relate mitomiRs to neurodegenerative diseases, including Alzheimer’s, Parkinson’s, and Huntington’s. We also discuss the involvement of mitomiRs in regulating the mitochondrial genome in age-related neurodegenerative diseases.

From its rapid spread to debilitating outcomes, the virus has wreaked havoc on healthcare systems around the world. As researchers study this novel virus, the public continues to seek more information on who is the most susceptible and which population will be affected by the more severe manifestations of the disease. As a result, scientists have started analyzing the variable effects of COVID-19 infection in different age groups. While the information is still nascent, these studies demonstrate that no one is immune, that all are susceptible to infection by this virus, and that certain demographics of the general population have more severe disease than others. This literature review examines how COVID-19 has affected different age groups, from neonates to older adults, by exploring statistics, mechanisms, and possible risk factors. This article will also investigate the role of comorbidities in increasing the severity ...
