Since its discovery in 2001, Human Metapneumovirus (hMPV) has been identified globally, exhibiting predictable seasonal outbreaks primarily affecting young children, the elderly, and individuals with preexisting health conditions. The virus is transmitted through airborne droplets and is responsible for a notable percentage of respiratory illnesses, particularly in children under five years of age, with hospitalization rates peaking in the first year of life. The complex immune response elicited by hMPV, characterized by a Th17-like profile and excessive mucus production, contributes to respiratory complications, emphasizing the need for effective management strategies. This review discusses various diagnostic methods, emphasizing the potential of combining serology with RT-PCR to enhance diagnostic accuracy during outbreaks. Furthermore, it addresses the therapeutic approaches, including the promise of recombinant interferons and ongoing research on the use of passive immunity through neutralizing antibodies. A comprehensive overview of hMPV, emphasizing the importance of continued research to improve diagnostic and therapeutic options for this significant respiratory pathogen, offers promising strategies for manipulating responses through targeted interventions.

Voltage‐gated calcium channels (VGCCs) are multi‐subunit ion channel proteins that control and regulate a wide array of physiological processes. Their dysfunction has been implicated in several neurological, cardiac, psychiatric, endocrine, oncogenic, and muscular disorders. The diverse and specialized cellular functions involving VGCC‐mediated calcium signaling stem from two primary mechanisms: differential and cell‐specific expression of pore‐forming (α1) and auxiliary subunit genes, and extensive alternative splicing of their pre‐mRNA. All the 10 α1‐encoding genes undergo alternative splicing to generate a wide array of cell‐specific CaV variants with distinct biophysical, pharmacological, and protein–protein interaction properties. This proteomic diversity and the associated cell‐specific expression signature of CaV splice variants are tightly regulated by trans‐acting splicing factors—RNA‐binding proteins that control the inclusion or skipping of alternatively spliced exons during post‐transcriptional pre‐mRNA processing. The discovery that several channelopathies are caused by aberrant splicing due to genetic mutations in either cis‐acting binding elements on the pre‐mRNA or in core splicing machinery components highlights the crucial role of alternative splicing in VGCC‐related pathologies. These insights have opened new therapeutic avenues, as targeting the alternative splicing of disease‐associated specific exons has recently emerged as a novel, promising treatment for neurodevelopmental disorders and channelopathies associated with splicing dysfunction.

In the United States, acute pancreatitis is one of the most common gastrointestinal conditions that results in hospital admission. Necrotizing pancreatitis is a form of acute pancreatitis that can lead to various local and systemic complications. It is also associated with a high risk of mortality and morbidity without prompt intervention. In this case report, we discuss the case of a 33-year-old female with a history of alcoholism hospitalized with necrotizing pancreatitis due to hypertriglyceridemia. Our goal was to promptly identify the case by evaluating the signs and symptoms and intervening to prevent the associated complications. Our other objective was to change the diet and lifestyle of the patient to prevent the recurrence of necrotizing pancreatitis and readmission for the same reason.

Alternative splicing and adenosine-to-inosine (A-to-I) RNA editing are post-transcriptional mechanisms that promote proteomic diversity in the brain. The impact of RNA editing on brain physiology is underscored by its association with the etiology and pathogenesis of various neurological and neurodegenerative diseases. Alternative splicing of exon 43 within the CaV1.3 C-terminus produces long (CaV1.3_L) and short (CaV1.3_43S) variants exhibiting distinct gating and pharmacological properties. While the physiological role of CaV1.3 A-to-I RNA editing in brain function is still unfolding, recent findings indicate that unedited CaV1.3 channels display larger calcium (Ca²⁺) influx and enhanced neuronal excitability, suggesting that A-to-I RNA editing may act as a negative regulator of neuronal Ca²⁺ signaling. However, it remains unclear which specific splice variants of CaV1.3 undergo RNA editing. We discovered an unexpected link between alternative splicing and RNA editing, where generation of the CaV1.3_43S variant results in a threefold increase in RNA editing at the IQ site. The CaV1.3_43S variant undergoes A-to-I RNA editing at two sites within its calmodulin-binding IQ domain, giving rise to three different edited variants. Functional analysis revealed that A-to-I RNA editing markedly decreases current density and induces a depolarizing shift in the current window, aligning the edited short variant's properties with those of the long variant. Our findings suggest that A-to-I RNA editing serves as a physiological mechanism regulating the “short” gating properties of the CaV1.3_43S variant and position A-to-I RNA editing of CaV1.3_43S variant as a neuroprotective physiological mechanism that prevents Ca²⁺ overload, especially in neurons susceptible to Ca²⁺ toxicity.
