The Effects of Smoking on Dental Implant Failure: A Current Literature Update.

This systematic review assesses the current literature (2020-2024) evaluating the impact of smoking on dental implant failure rates. A non-funded Pubmed database review was conducted according to PRISMA guidelines, and the results were tabulated to extract the study design, patient characteristics, follow-up time, comparison, outcome, and strengths and weaknesses, including risk of bias. This review included 33 studies with 29,519 implants placed in over 18,301 patients.

Understanding quality of life issues in patients with advanced melanoma: Phase 1 and 2 in the development of the EORTC advanced melanoma module.

Aims: We aimed to develop a European Organization for Research and Treatment of Cancer (EORTC) Quality of Life (QoL) module tailored for patients with advanced (resectable or unresectable stage III/IV) melanoma receiving immune checkpoint inhibitors or targeted therapy.

Methods: Following the EORTC QoL Group module development guidelines, we conducted phases 1 and 2 of the development process. In phase 1, we generated a list of health-related (HR)QoL issues through a systematic literature review and semi-structured interviews with healthcare professionals (HCPs) and patients with advanced melanoma.

The bevel effect: a prospective, randomized investigation into needle design in dental intraligamentary anesthesia.

Objectives: This in vivo study aimed to assess the impact of needle bevel design on puncture pain, anesthetic success, and mechanical deformations in intraligamentary injection (ILA) cases, comparing a short triple facet cut (STF) to a triple lancet cut (TL) after single or repetitive use.

Materials And Methods: In a prospective single-blind trial, 200 ILA needles (STF, n = 100; TL, n = 100) were randomly assigned for dental procedures. Patients received ILA either with STF or TL needles, used once (group A; n = 50 each) or repeatedly (group B; n = 50).

Identifying neuropeptide Y (NPY) as the main stress-related substrate of dipeptidyl peptidase 4 (DPP4) in blood circulation.

Background: Dipeptidyl peptidase 4 (DPP4; EC 3.4.14.

[Optical coherence tomography by evaluation of the spectral modulation of white light interferometry].

Amplitude and phase factor of a wave scattered from an object relative to the amplitude and phase factor of the incident wave reveals the spatial distribution of the object's scattering power by means of Fourier transform. In this paper this relation is discussed and the dependence of the spatial resolution and the maximal range of depth on the physical parameters as well as the influence of dispersion are investigated. The signal-to-noise ratio yields a measure on the sensitivity of the method which is put into relation of the sensitivity of Time-Domain Optical Coherence Tomography (TD-OCT).

Light hazards to the patient's retina from ophthalmic instruments.

The spectral radiance and irradiance of several common ophthalmic instruments were measured. The respective spectral retinal irradiance a patient might receive was calculated. To evaluate the potential light hazard to the patient's retina, we calculated the temperature rise resulting from light absorption at the fundus, compared retinal irradiance with threshold values for photochemical retinal damage, and correlated them with safety guidelines.

[Possible damage to the eye caused by light from ophthalmologic equipment].

Motivated by numerous findings of the damaging effect of intense light levels on the fundus we measured the spectral radiation of several ophthalmic illuminations and used it to calculate from it the spectral retinal irradiance. To evaluate the thermal hazard, we calculated the resulting temperature rise at the fundus. A measure for biological damage is the percentage of denaturated molecules, which is related to the temperature rise and its duration (essentially identical to the duration of illumination) by the so-called Arrhenius-integral.

[Stabilization of proximal femoral fractures using the compression and sliding screw].

Between 1979 and 1983 we treated 169 fractures with a sliding compression hip screw out of 402 operated fractures of the upper femur. The indication for this method included all types of proximal femoral fractures. In case of instable trochanteric fractures convincing results of treatment could be achieved because of early weight bearing.
