The clinical outcomes, including overall survival and progression-free survival (PFS), were compared across the treatment regimens and age groups using Kaplan-Meier survival curves and Cox proportional hazard models.

Current Evidence on the Relation Between Microbiota and Oral Cancer-The Role of -A Narrative Review.

Oral squamous cell carcinoma (OSCC) is one the most prevalent head and neck cancers and represents a major cause of morbidity and mortality worldwide. The main established risk factors for OSCC include tobacco and alcohol consumption and betel quid chewing, which may contribute alone or in combination with other environmental factors to carcinogenesis. The oral microbiota is emerging as a key player in the establishment of the molecular and cellular mechanisms that may trigger or promote carcinogenesis, including in the oral cavity.

Comprehensive Overview of Ketone Bodies in Cancer Metabolism: Mechanisms and Application.

Reprogramming energy metabolism is pivotal to tumor development. Ketone bodies (KBs), which are generated during lipid metabolism, are fundamental bioactive molecules that can be modulated to satisfy the escalating metabolic needs of cancer cells. At present, a burgeoning body of research is concentrating on the metabolism of KBs within tumors, investigating their roles as signaling mediators, drivers of post-translational modifications, and regulators of inflammation and oxidative stress.

Design: This was a sequentially initiated, dose-escalating cohort, placebo-controlled, double blind, randomized sequence, cross-over study of oral ketamine in 6-12-year-old girls with RTT to evaluate short-term safety and tolerability and explore efficacy.

Methods: Participants were randomized to either five days treatment with oral ketamine or matched placebo, followed by a nine-day wash-out period and then crossed-over to the opposite treatment.

Intratympanic administration of dexamethasone attenuates radiation induced damage to middle ear mucosa.

Radiotherapy (RTx) is a highly effective treatment for head and neck cancer that can cause concurrent damage to surrounding healthy tissues. In cases of nasopharyngeal carcinoma (NPC), the auditory apparatus is inevitably exposed to radiation fields and sustains considerable damage, resulting in dysfunction. To date, little research has been conducted on the changes induced by RTx in the middle ear and the underlying mechanisms involved.

Lysosomes finely control macrophage inflammatory function via regulating the release of lysosomal Fe through TRPML1 channel.

Lysosomes are best known for their roles in inflammatory responses by engaging in autophagy to remove inflammasomes. Here, we describe an unrecognized role for the lysosome, showing that it finely controls macrophage inflammatory function by manipulating the lysosomal Fe-prolyl hydroxylase domain enzymes (PHDs)-NF-κB-interleukin 1 beta (IL1B) transcription pathway that directly links lysosomes with inflammatory responses. TRPML1, a lysosomal cationic channel, is activated secondarily to ROS elevation upon inflammatory stimuli, which in turn suppresses IL1B transcription, thus limiting the excessive production of IL-1β in macrophages.

Roles of human papillomavirus in cancers: oncogenic mechanisms and clinical use.

Human papillomaviruses, particularly high-risk human papillomaviruses, have been universally considered to be associated with the oncogenesis and progression of various cancers. The genome of human papillomaviruses is circular, double-stranded DNA that encodes early and late proteins. Each of the proteins is of crucial significance in infecting the epithelium of host cells persistently and supporting viral genome integrating into host cells.

Dysphonia and Laryngopharyngeal Reflux.

Dysphonia is a common symptom of laryngopharyngeal reflux disease (LPRD) and requires multimodal, patient-centered care to address. Challenges in diagnosing LPRD can also complicate treatment of nonspecific dysphonia symptoms. Careful history taking with sensitivity to cultural lifestyle components in each patient is critical to management.

Peptide-modified nanoparticles for doxorubicin delivery: Strategies to overcome chemoresistance and perspectives on carbohydrate polymers.

Chemotherapy serves as the primary treatment for cancers, facing challenges due to the emergence of drug resistance. Combination therapy has been developed to combat cancer drug resistance, yet it still suffers from lack of specific targeting of cancer cells and poor accumulation at the tumor site. Consequently, targeted administration of chemotherapy medications has been employed in cancer treatment.

Design: Participants stood on foam placed on a force-platform, wore the HTC Vive headset, and observed an immersive subway environment.

Activation of S1PR2 on macrophages and the hepatocyte S1PR2/RhoA/ROCK1/MLC2 pathway in vanishing bile duct syndrome.

Immunologic bile duct destruction is a pathogenic condition associated with vanishing bile duct syndrome (VBDS) after liver transplantation and hematopoietic stem-cell transplantation. As the bile acid receptor sphingosine 1-phosphate receptor 2 (S1PR2) plays a critical role in recruitment of bone marrow-derived monocytes/macrophages to sites of cholestatic liver injury, S1PR2 expression was examined using cultured macrophages and patient tissues. Bile canaliculi destruction precedes intrahepatic ductopenia; therefore, we focused on hepatocyte S1PR2 and the downstream RhoA/Rho kinase 1 (ROCK1) signaling pathway and bile canaliculi alterations using three-dimensional hepatocyte culture models that form obvious bile canaliculus-like networks.

Exploratory Research: Patient-Reported Factors Contributing to Decreased Oral Intake During Radiotherapy in Head and Neck Cancer.

Background: Radiotherapy (RT) in head and neck cancer (HNC) can cause multiple side effects such as nausea, pain, taste loss, fatigue, oral mucositis, xerostomia, and acute radiation-associated dysphagia (RAD). These factors threaten patients' oral intake (OI) during this RT. Reduced OI can cause weight loss, dehydration, malnutrition, and various comorbidities.
