Efficacy of Infliximab Versus Vedolizumab in the Management of Immune Checkpoint Inhibitor-Induced Colitis: A Systematic Review and Meta-Analysis.

Background: Immune checkpoint inhibitors (ICIs) can cause severe gastrointestinal immune-related adverse events (irAEs), often leading to treatment interruption and increased morbidity. Immune-mediated colitis (IMC) ranges from mild diarrhea to life-threatening colitis, sometimes requiring urgent intervention. While corticosteroids are the first-line treatment, selective immunosuppressive therapy (SIT) with either infliximab or vedolizumab is used for steroid-refractory or dependent cases.

TAS-102, Irinotecan, and bevacizumab in pre-treated metastatic colorectal cancer (TABAsCO), a phase II clinical trial.

Background: The efficacy of FOLFIRI plus an antiangiogenesis biologic agent as 2nd line therapy for metastatic colorectal adenocarcinoma is limited. TAS-102 is a novel oral antimetabolite with a distinct mechanism of action from fluoropyrimidines. We evaluated the antitumour efficacy of TAS-102, irinotecan and bevacizumab in patients with pre-treated, advanced colorectal adenocarcinoma in a multicenter, phase II, single-arm study.

Comparison of ChatGPT and Traditional Patient Education Materials for Men's Health.

Introduction: ChatGPT is an artificial intelligence platform available to patients seeking medical advice. Traditionally, urology patients consulted official provider-created materials, particularly the Urology Care Foundation™ (UCF). Today, men increasingly go online due to the rising costs of health care and the stigma surrounding sexual health.

Erectile dysfunction (ED) is widely prevalent and has diverse management options which are poorly understood and accessed by patients. This cross-sectional TikTok study aimed to evaluate the quality of ED educational materials and define trends in healthcare provider content development. Three reviewers independently analyzed 50 videos.

Exact analytic solution for a chaotic hybrid dynamical system and its electronic realization.

A novel hybrid dynamical system comprising a continuous and a discrete state is introduced and shown to exhibit chaotic dynamics. The system includes an unstable first-order filter subject to asynchronous switching of a set point according to a feedback rule. Regular samples of the continuous state yield a one-dimensional return map that is a tent function.

Generating and Detecting Solvable Chaos at Radio Frequencies with Consideration to Multi-User Ranging.

High entropy waveforms exhibit desirable correlation properties in radar and sonar applications when multiple systems are used in close proximity. Unfortunately, the information content of these signals can impose high sampling requirements for digital detection techniques. Solvable chaotic oscillators have been proposed to address such issues due to their simple, matched filters, where hardware has been demonstrated with a bandwidth of 10-20 kHz.

Rationale for Haze Formation after Carboxymethyl Cellulose (CMC) Addition to Red Wine.

The aim of this study was to identify the source of haze formation in red wine after the addition of carboxymethyl cellulose (CMC) and to characterize the dynamics of precipitation. Ninety commercial wines representing eight grape varieties were collected, tested with two commercial CMC products, and analyzed for susceptibility to haze formation. Seventy-four of these wines showed a precipitation within 14 days independent of the CMC product used.

The Challenge of Erectile Dysfunction Management in the Young Man.

Erectile dysfunction (ED) in a young man is an important health problem that significantly impacts the patient's quality of life and can have a detrimental effect on his well-being and relationship with his partner. Erectile dysfunction or impotence is one of the few disorders that will bring a young man into the doctor's office. This review article focuses on the epidemiology, etiology, presentation, work-up, and treatment of young men (age ~20-40 years old) presenting with complaints of ED.

Structured scale dependence in the Lyapunov exponent of a Boolean chaotic map.

We report on structures in a scale-dependent Lyapunov exponent of an experimental chaotic map that arise due to discontinuities in the map. The chaos is realized in an autonomous Boolean network, which is constructed using asynchronous logic gates to form a map operator that outputs an unclocked pulse-train of varying widths. The map operator executes pulse-width stretching and folding and the operator's output is fed back to its input to continuously iterate the map.

Development of penile hydrocele following placement of inflatable penile prosthesis: a rare entity.

Introduction: The development of a penile hydrocele following the placement of an inflatable penile prosthesis (IPP) for erectile dysfunction has never been documented. We herein report an unusual complication of penile hydrocele formation that developed following placement of an IPP for erectile dysfunction.

Methods: The penile hydrocele was successfully repaired by excision of the hydrocele sac.

Multidimensional subwavelength position sensing using a semiconductor laser with optical feedback.

We demonstrate experimentally how to harness quasi-periodic dynamics in a semiconductor laser with dual optical feedback for measuring subwavelength changes in each arm of the cavity simultaneously. We exploit the multifrequency spectrum of quasi-periodic dynamics and show that independent frequency shifts are mapped uniquely to two-dimensional displacements of the arms in the external cavity. Considering a laser diode operating at telecommunication wavelength λ≈1550 nm, we achieve an average nanoscale resolution of approximately 9.

A pseudo-matched filter for chaos.

A matched filter maximizes the signal-to-noise ratio of a signal. In the recent work of Corron et al. [Chaos 20, 023123 (2010)], a matched filter is derived for the chaotic waveforms produced by a piecewise-linear system.

Single-surgeon experience of 87 buccal mucosal graft harvests.

Unlabelled: Although buccal mucosa has been the preferred graft material for use in the reconstruction of anterior urethral strictures for approximately 20 years, the plastic surgery literature is lacking in studies describing and evaluating this technique. The authors sought to report their experience with the technique of buccal mucosa graft harvest for use in urethral reconstruction. The authors identified 87 consecutive patients who underwent buccal mucosal graft harvesting during a 15-year period from 1995 to 2010.

Impact of diurnal temperature variation on grape berry development, proanthocyanidin accumulation, and the expression of flavonoid pathway genes.

Little is known about the impact of temperature on proanthocyanidin (PA) accumulation in grape skins, despite its significance in berry composition and wine quality. Field-grown grapes (cv. Merlot) were cooled during the day or heated at night by +/-8 °C, from fruit set to véraison in three seasons, to determine the effect of temperature on PA accumulation.

Subwavelength position sensing using nonlinear feedback and wave chaos.

We demonstrate a position-sensing technique that relies on the inherent sensitivity of chaos, where we illuminate a subwavelength object with a complex structured radio-frequency field generated using wave chaos and nonlinear feedback. We operate the system in a quasiperiodic state and analyze changes in the frequency content of the scalar voltage signal in the feedback loop. This allows us to extract the object's position with a one-dimensional resolution of ~λ/10,000 and a two-dimensional resolution of ~λ/300, where λ is the shortest wavelength of the illuminating source.

Assessing the impact of temperature on grape phenolic metabolism.

This study assessed the impact of fruit temperature on the phenolic metabolism of grape berries (Vitis vinifera L. cv. Merlot) grown under field conditions with controlled exposure to sunlight.

Sedation for the relief of refractory symptoms in the imminently dying: a fine intentional line.

There is a continuum of the goals of comfort and function in palliative care that begins with comfort and function being equal priorities and sedation being unacceptable. As disease progresses, the goals and preferences of the patient turn to coping with the loss of function caused by the disease and acceptance of unintentional sedation from the disease, its therapies, or symptom relief interventions. As patients approach the end of life, they may need intentional sedation for the relief of refractory symptoms.
