Virtual reality-based Harms tangent screen test for strabismus measurement.

Purpose: Our study presents a virtual reality-based tangent screen test (VTS) to measure subjective ocular deviations including torsion in nine directions of gaze. The test was compared to the analogous Harms tangent screen test (HTS).

Methods: We used an Oculus Go controller and head-mounted-display with rotation sensors to measure patient's head orientation for the VTS.

Cerebrovascular regulation in patients with active tumors and an acute ischemic stroke: a retrospective analysis.

Introduction: Ischemic stroke in patients with a systemic tumor disease or cancer not in remission (active tumors) is less well understood. Some aspects of such paraneoplastic strokes remind on a generalized cerebrovascular disorder. We hypothesized that cerebrovascular regulation in active tumor patients with a stroke is different from other patients with stroke who have no active tumor disease.

RNA Modifications and Their Role in Regulating KSHV Replication and Pathogenic Mechanisms.

Kaposi's sarcoma-associated herpesvirus is an oncogenic gammaherpesvirus that plays a major role in several human malignancies, including Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. The complexity of KSHV biology is reflected in the sophisticated regulation of its biphasic life cycle, consisting of a quiescent latent phase and virion-producing lytic replication. KSHV expresses coding and noncoding RNAs, including microRNAs and long noncoding RNAs, which play crucial roles in modulating viral gene expression, immune evasion, and intercellular communication.

[A new validated ophthalmic patient questionnaire for cataract and lens surgery : CLOQ: cataract and lens ophthalmic questionnaire].

Background: The new patient cataract and lens ophthalmic questionnaire (CLOQ) determines subjective patient satisfaction before and after cataract surgery according to item response theory (IRT).

Methods: A total of 317 patients with bilateral cataract surgery and implantation of different intraocular lens (IOL) types were included. The questionnaire (37 questions) is divided into questions on visual acuity-relevant quality of life (VRQoL), quality of vision (QoV), spectacle dependence, and general satisfaction.

[Perioperative management with consumption of alcohol and nicotine in patients with hip and knee arthroplasty].

Excessive consumption of nicotine and alcohol has been proven to effect the organ system. Both stimulants are consumed in the population to a not insignificant extent. The question therefore arises as to what effect the consumption of nicotine and alcohol has on the complication rates and to what extent this should be reduced or stopped before performing a joint arthroplasty? A literature search was carried out to answer these questions.
