Investigating Fryette's mechanics in computed tomography scans: an analysis of vertebrae spinal physiology using open-sourced datasets and three-dimensional vertebral orientation.

Context: Fryette's mechanics is taught as a simplistic model of coupled vertebral movement, fundamental in osteopathic practice. This study seeks to better understand the likelihood of Fryette's model by calculating vertebral orientation in computed tomography (CT) scans. Given previous findings of low angular coupled movements during overall spinal motion, static calculations provide a unique perspective on the likelihood of Fryette's mechanics.

Neurocysticercosis: A Challenging Case in New Mexico.

Neurocysticercosis, a parasitic infection caused by the larvae of , presents a diagnostic challenge, particularly in non-endemic regions. This case report evaluates the intricacies of diagnosing neurocysticercosis in a 62-year-old male presenting with an intractable headache and altered mental status, initially confounded by the absence of an exposure history. Despite lacking typical risk factors, including immunocompromise or HIV infection, his travel history to an endemic area prompted a rigorous clinical work-up.

Pre-operative Embolization of a Cerebellar Hemangioblastoma Using Polyvinyl Alcohol (PVA) and Target Tetra 360 Detachable Coil.

Due to its hypervascularity, hemangioblastoma, a rare primary central nervous system intracranial tumor, has been treated with pre-operative embolization prior to surgical resection. Here, we describe a case treated as such. A 37-year-old male presented with worsening chronic headache and right ear tinnitus was found to have a hypervascular, heterogeneous right cerebellar lesion suspicious for arteriovenous malformation or hemangioblastoma.

A framework for the interpretation of heart rate variability applied to transcutaneous auricular vagus nerve stimulation and osteopathic manipulation.

Reports on autonomic responses to transcutaneous auricular vagus nerve stimulation (taVNS) and osteopathic manipulative techniques have been equivocal, partly due to inconsistent interpretation of heart rate variability (HRV). We developed a mechanistic framework for the interpretation of HRV based on a model of sinus node automaticity that considers autonomic effects on Phase 3 repolarization and Phase 4 depolarization of the sinoatrial action potential. The model was applied to HRV parameters calculated from ECG recordings (healthy adult humans, both genders) before (30 min), during (15 min), and after (30 min) a time control intervention (rest, n = 23), taVNS (10 Hz, 300 μs, 1-2 mA, cymba concha, left ear, n = 12), or occipitoatlantal decompression (OA-D, n = 14).

HSPA9/mortalin inhibition disrupts erythroid maturation through a TP53-dependent mechanism in human CD34+ hematopoietic progenitor cells.

Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic stem cell malignancies characterized by abnormal hematopoietic cell maturation, increased apoptosis of bone marrow cells, and anemia. They are the most common myeloid blood cancers in American adults. The full complement of gene mutations that contribute to the phenotypes or clinical symptoms in MDS is not fully understood.

Coexistence of anti-NMDAR and anti-IgLON5 antibodies in an autoimmune encephalitis patient: The first case report.

Background: The coexistence of autoimmune encephalitis (AE) with multiple neural auto-antibodies is of great clinical significance because overlying antibodies may cause superposition or variation of clinical syndrome, which increases the difficulty of diagnosis and treatment of the disease. To the best of our knowledge, the coexistence of anti-N-methyl d-aspartate Receptor (NMDAR) and anti-IgLON5 antibodies in AE has not been published previously.

Case Presentation: A 38-year-old female patient presented to our hospital due to headache and abnormal psychiatric behavior.

Global incidence of adverse clinical events in non-alcoholic fatty liver disease: A systematic review and meta-analysis.

Background/aims: Nonalcoholic fatty liver disease (NAFLD) is associated with a multitude of adverse outcomes. We aimed to estimate the pooled incidence of NAFLD-related adverse events.

Methods: We performed a systematic review and meta-analysis of cohort studies of adults with NAFLD to evaluate the pooled incidence of adverse events.

Exercise and inflammatory cytokine regulation among older adults with myeloid malignancies.

Tumor necrosis factor (TNF)α is a major regulator of inflammation. However, the epigenetic regulation of TNFα in the context of an exercise intervention among older adults with cancer is understudied. In this exploratory analysis, we used data from a single-arm mobile health (mHealth) exercise intervention among older adults with myeloid malignancies to 1) assess changes in TNFα promoter methylation, TNFα mRNA expression, serum TNFα and other related-cytokine levels after intervention; and 2) assess correlations between blood markers and exercise levels.

Inadequate harms reporting among randomized controlled trials cited as supporting evidence in the AAOS management of hip fractures in older adults clinical practice guideline recommendations.

Background: Recommendations within clinical practice guidelines (CPGs) are heavily influenced by results from randomized controlled trials (RCTs). Therefore, it is imperative that all RCT outcomes are reported thoroughly to ensure CPGs are created using accurate information. Here, we evaluate the quality of harms reporting using the CONSORT Extension for Harms in RCTs underpinning recommendations in the American Academy of Orthopedic Surgeons (AAOS) Management of Hip Fractures in Older Adults CPG.

Higher risk of Achilles tendon ruptures at competition than training sites in female collegiate gymnasts.

Background: Reportedly, 17.2% of collegiate female gymnasts experience Achilles tendon ruptures (ATRs). Cumulative microtraumas resulting in chronic tendinopathy/tendinitis may contribute to this high injury risk.

Case Report: Heterotopic Pancreatic Tissue Leading to Acute on Chronic Cholecystitis.

Heterotopic (ectopic) pancreatic tissue refers to tissue located outside the borders of the main pancreas. It is rarely found in gallbladders and can cause biliary disease, with only a few documented cases in the surgical literature. Here, we present the unusual case of a 21-year-old female with acute on chronic cholecystitis caused by obstruction of the cystic duct with ectopic pancreatic tissue.

XX Male: Early Detection With Prenatal Testing.

A 46,XX male represents a variant of Klinefelter syndrome (47,XXY), under the category of a disorder of sex development (DSD). Despite possessing an XX karyotype, these individuals exhibit a male phenotype, which, in this case, results from a translocation of the SRY gene from the Y chromosome onto the X chromosome. This genetic alteration results in the development of male gonadal characteristics.

The Role of Medication, Mental Illness, and Social Isolation on the Development of the Fetus in the Context of the COVID-19 Pandemic.

As we enter the COVID-19 post-pandemic period, uncertainty surrounds the impact of the varied effects of medications, mental illness, and social isolation on children born during the pandemic. Medications like selective serotonin reuptake inhibitors (SSRIs) and benzodiazepines during pregnancy, coupled with pandemic-induced social isolation, may contribute to anxiety, depression, and behavioral issues in the offspring. Supporting evidence shows SSRIs' influence on brain development, while third-trimester benzodiazepine use may lead to neonatal withdrawal syndrome.

Unilateral foot drop due to prone positioning in COVID-19: A case report.

Key Clinical Message: Understanding the complications arising from prone positioning following mechanical ventilation during management of acute respiratory distress from COVID-19.

Abstract: Acute respiratory distress syndrome (ARDS) resulting from coronavirus disease 2019 (COVID-19) has been one of the well-known complications of the disease since it was first reported in 2020. Mechanical ventilation for severe ARDS has been widely utilized for the management of such patients.

Using artificial intelligence to grade practical laboratory examinations: Sacrificing students' learning experiences for saving time?

The use of artificial intelligence (AI) by students has recently been made a key topic among educators because of the potential to transform students' learning experiences. However, the use of AI-based software by instructors has not received the same level of consideration despite its recent accessibility and prevalence. This contribution discusses the benefits, challenges, and limitations of commercial AI-based software (Gradescope) for grading summative, short answer practical examinations in an undergraduate gross anatomy course.

Novel Case of Streptococcus Mitis-infected Chronic Subdural Hematoma.
