When Bell's Palsy Is Cancer: Avoiding Misdiagnosis and Its Implications.

Background:  Facial paralysis due to cancer can be misdiagnosed as Bell's palsy. This study aims to clearly identify and quantify diagnostic differentiators and further evaluate the prognostic implications of misdiagnosis.

Methods:  Adult patients older than 18 years with facial palsy of unknown or cancerous etiology presenting between 2009 and 2023 were reviewed.

Development of a + Cardiac Mouse Progenitor Immortalized Model to Unravel the Relationship with Its Protective Vascular Endothelial Niche.

The adult mammalian heart has been demonstrated to be endowed with low but real turnover capacity, especially for cardiomyocytes, the key functional cell type. The source, however, of that turnover capacity remains controversial. In this regard, we have defined and characterized a resident multipotent cardiac mouse progenitor population, +DR (for + Damage-Responsive cells).

Study on the interference of vaccine antibodies with the serological diagnosis of leptospirosis in cattle.

A simple IgG-specific ELISA for Leptospira spp. was compared with the microscopic agglutination test (MAT) to detect IgG antibody responses to a commercial vaccine in cattle. We used an enzyme-linked immunosorbent assay (ELISA) with sonicated Leptospira interrogans serovar copenhageni M 20.

Myelin oligodendrocyte glycoprotein reactive Th17 cells drive Janus Kinase 1 dependent transcriptional reprogramming in astrocytes and alter cell surface cytokine receptor profiles during experimental autoimmune encephalomyelitis.

Multiple sclerosis (MS) is an autoimmune demyelinating disease affecting the central nervous system (CNS). T helper (Th) 17 cells are involved in the pathogenesis of MS and its animal model of experimental autoimmune encephalomyelitis (EAE) by infiltrating the CNS and producing effector molecules that engage resident glial cells. Among these glial cells, astrocytes have a central role in coordinating inflammatory processes by responding to cytokines and chemokines released by Th17 cells.

Distinct immunometabolic signatures in circulating immune cells define disease outcome in acute-on-chronic liver failure.

Background And Aims: Acute-on-chronic liver failure (ACLF) is a complication of cirrhosis characterized by multiple organ failure and high short-term mortality. The pathophysiology of ACLF involves elevated systemic inflammation leading to organ failure, along with immune dysfunction that heightens susceptibility to bacterial infections. However, it is unclear how these aspects are associated with recovery and nonrecovery in ACLF.

Polyetheretherketone Implant Cranioplasty for Large Cranial Defects: A Seven-Year Follow-Up.

Background: Goals of a cranioplasty include protection of the brain, restoration of normal appearance, and neurological function improvement. Although choice of materials for cranial remodeling has changed through the years, computer-designed polyetheretherketone (PEEK) implant has gained traction as a preferred material used for cranioplasty. However, long-term outcomes and complications of PEEK implants remain limited.

Postparetic Synkinesis: Objective and Subjective Comparisons of Depressor Anguli Oris Myectomies versus Depressor Anguli Oris and Buccinator Myectomies.

Background:  Muscles affected by postparetic synkinesis have imbalanced tonicity that limit perioral mimetic movement and inhibit the ability to smile. The depressor anguli oris (DAO) muscle has been a common myectomy target for the treatment of perioral synkinesis. While addition of buccinator myectomies to DAO myectomies has risen, no studies have analyzed the effects of buccinator myectomies.

Negative Impact of Synkinetic Mentalis Muscle on Smile Quality: Pathomechanism and Treatment with Mentalis-Targeted Selective Neurectomies.

Background: The treatment of postparetic facial synkinesis is based on a combination of nonsurgical and surgical strategies. Improvements toward the restoration of a natural smile have been obtained with selective neurectomies and depressor anguli oris myectomy, but the lower lip frequently remains asymmetric and cranially displaced. The aim of this study was to evaluate the effect of the mentalis muscle on the position and symmetry of the lower lip in patients with synkinesis and to assess the added benefit of neurectomies of nerves innervating the mentalis muscle in improving the lower lip configuration and mandibular teeth show.

Effect of Lower Extremity Nerve Decompression in Patients With Painful Diabetic Peripheral Neuropathy: The Diabetic Neuropathy Nerve Decompression Randomized, Observation Group and Placebo Surgery-Controlled Clinical Trial.

Objective: To evaluate the effect of nerve decompression on pain in patients with lower extremity painful diabetic peripheral neuropathy (DPN).

Background: Currently, no treatment provides lasting relief for patients with DPN. The benefits of nerve decompression remain inconclusive.

Selective Myectomies Alone versus Selective Myectomies Combined with Neurectomies in Postparetic Synkinesis: Comparing Outcomes.

Background: In postparetic synkinesis, muscle tone imbalance between upper and lower lip depressors and elevators results in the inability to produce an effective smile. Surgical treatments to improve smile focus on restoring tonicity balance between perioral muscles by weakening hypertoned muscles through selective myectomies or selective neurectomies. The goal of this study was to compare objective outcomes between selective myectomies alone with those of selective myectomies combined with selective neurectomies.

Use of Transesophageal Echocardiography During Orthotopic Liver Transplantation: Simplifying the Procedure.

The intraoperative management of patients undergoing orthotopic liver transplantation (OLT) is influenced by the cardiovascular manifestations typically found in the context of end-stage liver disease, by the presence of concomitant cardiovascular disease, and by the significant hemodynamic changes that occur during surgery. Hypotension and intraoperative blood pressure fluctuations during OLT are associated with liver graft dysfunction, acute kidney failure, and increased risk of 30-d mortality. Patients also frequently present hemodynamic instability due to various causes, including cardiac arrest.

Dual-Innervated Gracilis Free Functional Muscle Transfers in Facial Palsy Patients: Comparing Long-Term Outcomes between One- versus Two-Stage Procedures.

Background:  In facial reanimation, dual-innervated gracilis free functional muscle transfers (FFMTs) may have amalgamated increases in tone, excursion, synchroneity, and potentially spontaneity when compared with single innervation. The ideal staging of dual-innervated gracilis FFMTs has not been investigated. We aim to compare objective long-term outcomes following one- and two-stage dual-innervated gracilis FFMTs.

Fatty acid amide hydrolase drives adult mammary gland development by promoting luminal cell differentiation.

Mammary gland development occurs primarily in adulthood, undergoing extensive expansion during puberty followed by cycles of functional specialization and regression with every round of pregnancy/lactation/involution. This process is ultimately driven by the coordinated proliferation and differentiation of mammary epithelial cells. However, the endogenous molecular factors regulating these developmental dynamics are still poorly defined.

Human gelatin thrombin matrix with rifampin for the treatment of prosthetic vascular graft infections.

We aim to describe and report on a novel graft preservation technique using a human gelatin thrombin matrix with rifampin for the treatment of vascular graft infections. Eight patients with vascular graft infections were included, one with bilateral infections, for a total of nine cases from January 2016 through June 2021. All the patients underwent wound exploration and placement of human gelatin thrombin matrix with rifampin.

Serological response and breakthrough infection after COVID-19 vaccination in patients with cirrhosis and post-liver transplant.

Background: Vaccine hesitancy and lack of access remain major issues in disseminating COVID-19 vaccination to liver patients globally. Factors predicting poor response to vaccination and risk of breakthrough infection are important data to target booster vaccine programs. The primary aim of the current study was to measure humoral responses to 2 doses of COVID-19 vaccine.

Dual versus Single Innervation of Gracilis Free Functional Muscle Transfer in Facial Paralysis: Long-Term Resting and Dynamic Outcomes.

Background: The purpose of this study was to compare long-term tone and excursion in single- versus dual-innervated free functional muscle transfer (FFMT) in patients with longstanding facial paralysis.

Methods: Patients with longstanding facial palsy treated with an FFMT innervated either by a nerve-to-masseter graft (single-innervation group) or nerve-to-masseter and cross-facial-nerve grafts (dual-innervation group) were included. One-year minimum follow-up was required.

miR-203 drives breast cancer cell differentiation.

A hallmark of many malignant tumors is dedifferentiated (immature) cells bearing slight or no resemblance to the normal cells from which the cancer originated. Tumor dedifferentiated cells exhibit a higher capacity to survive to chemo and radiotherapies and have the ability to incite tumor relapse. Inducing cancer cell differentiation would abolish their self-renewal and invasive capacity and could be combined with the current standard of care, especially in poorly differentiated and aggressive tumors (with worst prognosis).

Optimization and comparative analysis of LAMP and PCR techniques for the detection of leptospiral DNA in Golden Syrian hamsters.

Leptospirosis is a zoonotic disease with significant public health and economic impact worldwide. Rapid and accurate diagnosis is essential for effective prevention and treatment. This study optimized a loop-mediated isothermal amplification (LAMP) assay using BFo isothermal DNA polymerase with different colorimetric indicators.

Exploring the 1,3-benzoxazine chemotype for cannabinoid receptor 2 as a promising anti-cancer therapeutic.

The discovery of selective agonists of cannabinoid receptor 2 (CB) is strongly pursued to successfully tuning endocannabinoid signaling for therapeutic purposes. However, the design of selective CB agonists is still challenging because of the high homology with the cannabinoid receptor 1 (CB) and for the yet unclear molecular basis of the agonist/antagonist switch. Here, the 1,3-benzoxazine scaffold is presented as a versatile chemotype for the design of CB agonists from which 25 derivatives were synthesized.

Identification of fatty acid amide hydrolase as a metastasis suppressor in breast cancer.

Clinical management of breast cancer (BC) metastasis remains an unmet need as it accounts for 90% of BC-associated mortality. Although the luminal subtype, which represents >70% of BC cases, is generally associated with a favorable outcome, it is susceptible to metastatic relapse as late as 15 years after treatment discontinuation. Seeking therapeutic approaches as well as screening tools to properly identify those patients with a higher risk of recurrence is therefore essential.

Can Pyridoxine Successfully Reduce Behavioral Side Effects from Levetiracetam?: A Critically Appraised Topic.

Background: Levetiracetam is a commonly used anti-seizure medication, with the development of neuropsychiatric symptoms being the most common side effect. Preliminary literature describes the improvement of these symptoms with pyridoxine, mostly within the pediatric population. However, randomized control trial data investigating this relationship is sparse.

Lateral Tarsal Strip versus Tensor Fascia Lata Sling for Paralytic Ectropion: Comparison and Long-Term Outcomes.

Background: Paralytic ectropion increases risk for corneal injury in facial palsy patients. Although a lateral tarsal strip (LTS) provides corneal coverage through superolateral lower eyelid pull, the unopposed lateral force may result in lateral displacement of the lower eyelid punctum and overall worsening asymmetry. A tensor fascia lata (TFL) lower eyelid sling may overcome some of these limitations.
