Low Escitalopram Concentrations in Patients with Depression predict Treatment Failure: A Naturalistic Retrospective Study.

Introduction: Cross sectional therapeutic drug monitoring (TDM) data mining introduces new opportunities for the investigation of medication treatment effects to find optimal therapeutic windows. Medication discontinuation has been proven useful as an objective surrogate marker to assess treatment failure. This study aimed to investigate the treatment effects of escitalopram and pharmacokinetic influences on blood levels using retrospectively assessed data from a TDM database.

The impact of shape and attachment position of biologging devices in Northern Bald Ibises.

Background: The impact of biologging devices on the aerodynamics or hydrodynamics of animals is still poorly understood. This stands in marked contrast to the ever more extensive use of such technologies in wild-living animals. Recently, increasing concerns have been raised about the impairing effects of these devices on the animals concerned.

Possibilities of Real Time Monitoring of Micropollutants in Wastewater Using Laser-Induced Raman & Fluorescence Spectroscopy (LIRFS) and Artificial Intelligence (AI).

The entire water cycle is contaminated with largely undetected micropollutants, thus jeopardizing wastewater treatment. Currently, monitoring methods that are used by wastewater treatment plants (WWTP) are not able to detect these micropollutants, causing negative effects on aquatic ecosystems and human health. In our case study, we took collective samples around different treatment stages (aeration tank, membrane bioreactor, ozonation) of a WWTP and analyzed them via Deep-UV laser-induced Raman and fluorescence spectroscopy (LIRFS) in combination with a CNN-based AI support.

A low-cost wind tunnel for bird flight experiments.

Unlabelled: A blower-type wind tunnel for physiological bird flight experiments has been developed, constructed and evaluated. Since the birds to be investigated are rather big (Northern Bald Ibis, ), the cross-sectional area of the test section measures 2.5 m × 1.

Application of Laser-Induced, Deep UV Raman Spectroscopy and Artificial Intelligence in Real-Time Environmental Monitoring-Solutions and First Results.

Environmental monitoring of aquatic systems is the key requirement for sustainable environmental protection and future drinking water supply. The quality of water resources depends on the effectiveness of water treatment plants to reduce chemical pollutants, such as nitrates, pharmaceuticals, or microplastics. Changes in water quality can vary rapidly and must be monitored in real-time, enabling immediate action.

Site-selection criteria for the Einstein Telescope.

The Einstein Telescope (ET) is a proposed next-generation, underground gravitational-wave detector to be based in Europe. It will provide about an order of magnitude sensitivity increase with respect to the currently operating detectors and, also extend the observation band targeting frequencies as low as 3 Hz. One of the first decisions that needs to be made is about the future ET site following an in-depth site characterization.

In situ observation of helium and argon release during fluid-pressure-triggered rock deformation.

Temporal changes in groundwater chemistry can reveal information about the evolution of flow path connectivity during crustal deformation. Here, we report transient helium and argon concentration anomalies monitored during a series of hydraulic reservoir stimulation experiments measured with an in situ gas equilibrium membrane inlet mass spectrometer. Geodetic and seismic analyses revealed that the applied stimulation treatments led to the formation of new fractures (hydraulic fracturing) and the reactivation of natural fractures (hydraulic shearing), both of which remobilized (He, Ar)-enriched fluids trapped in the rock mass.

Comprehensive geological dataset describing a crystalline rock mass for hydraulic stimulation experiments.

High-resolution 3D geological models are crucial for underground development projects and corresponding numerical simulations with applications in e.g., tunneling, hydrocarbon exploration, geothermal exploitation and mining.

Value of Provoked or Spontaneous Flank Pain in Men with Febrile Urinary Tract Infections.

Background: Our objective was to identify the clinical, laboratory and radiological characteristics of febrile urinary tract infections (UTI) in men and to focus on the value of flank pain in these men managed in an ambulatory care system.

Methods: A network was designed to manage men with febrile UTI without hospitalization according to an algorithm designed with different specialists. The patients' characteristics were prospectively recorded and each patient was followed up until completely cured.

Impact of body mass index on the one-year clinical outcome of patients undergoing multivessel revascularization with sirolimus-eluting stents (from the Arterial Revascularization Therapies Study Part II).

The differential safety and efficacy profiles of sirolimus-eluting stents when implanted in patients with multivessel coronary artery disease who have increased body mass indexes (BMIs) compared with those with normal BMIs are largely unknown. This study evaluated the impact of BMI on 1-year outcomes in patients with multivessel coronary artery disease treated with sirolimus-eluting stents as part of the Arterial Revascularization Therapies Study Part II (ARTS II). From February to November 2003, 607 patients were included at 45 centers; 176 patients had normal BMIs (<25 kg/m(2)), 289 were overweight (> or =25 and < or =30 kg/m(2)), and 142 were obese (>30 kg/m(2)).

Tormentil for active ulcerative colitis: an open-label, dose-escalating study.

Background: Tormentil extracts (TE) have antioxidative properties and are used as a complementary therapy for chronic inflammatory bowel disease. In individual patients with ulcerative colitis (UC) positive effects have been observed.

Goals: To assess the safety, pharmacology, and clinical effects of different doses of TE in patients with active UC.

Distal embolic protection during percutaneous coronary intervention in patients with acute coronary syndromes: the RUBY study.

Objective: To assess the safety and feasibility of the GuardWire system as an embolic protection device during percutaneous coronary intervention (PCI) in acute coronary syndromes (ACS).

Background: Distal embolization occurs in approximately 15% of patients after primary angioplasty and is associated with reduced myocardial reperfusion, more extensive myocardial damage and a poor prognosis. Distal embolic protection could reduce the rate of embolic complications and improve outcome.

[Coronary stents].

Since the introduction of coronary stents into clinical practice in the late 1980s, the number of stent implantations has increased so rapidly that stents are currently used in over 80 percent of all percutaneous coronary interventions. Although stent implantation was initially limited to large vessels with proximal and discrete lesions, improvements in stent design and implantation technique now allow their deployment in more complex lesions in smaller and diffusely diseased vessels. The overall acceptance of stents by interventional cardiologists can be attributed to favorable acute and longterm results compared to balloon angioplasty alone.

Clinical and quantitative angiographic outcomes following elective implantation of the self-expanding Wallstent for longer coronary artery lesions--final results of the Wellstent native study.

BACKGROUND: Implantation of short balloon-expandable stents provides superior clinical and angiographic outcome compared with balloon angioplasty in selected patients. The purpose of the Wellstent study was to evaluate the safety and efficacy of the self-expanding Wallstent combined with aspirin and ticlopidine in patients with stable or unstable angina related to a native coronary lesion up to 45 mm in length. METHODS: 105 patients (111 lesions) with stable (57%) or unstable (43%) angina were included in this prospective multicentre evaluation.

Comparison of costs and safety of a suture-mediated closure device with conventional manual compression after coronary artery interventions.

The aim of this study was to assess costs and safety of immediate femoral sheath removal and closure with a suture-mediated closure device (Perclose, Menlo Park, CA) in patients undergoing elective (PCI). A total of 193 patients was prospectively randomized to immediate arterial sheath removal and access site closure with a suture-mediated closure device (SMC; n = 96) or sheath removal 4 hr after PCI followed by manual compression (MC; n = 97). In the SMC group, patients were ambulated 4 hr after elective PCI if hemostasis was achieved.

High density-lipoprotein subfractions of patients using cardio-selective beta-blockers.

Treatment of hypertension with beta-adrenergic blockers (BB) slightly increases plasma triglycerides and decreases high density lipoprotein (HDL) cholesterol levels. However, only little is known about BB-related lipid changes in patients with coronary artery disease (CAD), who usually a priori have decreased HDL cholesterol levels; and even less data exist on HDL subfraction cholesterol in these patients. We therefore quantified levels of lipids, lipoprotein lipids including HDL2 and HDL3 cholesterol, and apolipoproteins in 107 consecutive men undergoing elective coronary angiography.

[Medicamentous management of acute coronary syndrome without ST segment elevation].

Recent advances in the recognition and the treatment of acute coronary syndromes (ACS) have lead to an improvement in patient survival and definition of newer guidelines. Current strategies for the treatment of patients with non-ST-elevation ACS include anti-ischemic and antiplatelet medications. While aspirin, beta-blockers, heparin and nitrates are still common practice, the advent of newer anticoagulants (low molecular weight heparins) and antiplatelet agents (glycoprotein llb/IIIa inhibitors and thienopyridines like ticlopidin and clopidogrel) and, possibly, aggressive lipid lowering with statins have added significant benefits to the treatment options with a better prognosis for these patients.

Percutaneous transluminal therapeutic ultrasound for high-risk thrombus-containing lesions in native coronary arteries.

We assessed the short-term outcome of percutaneous coronary ultrasound thrombolysis (CUT) for high-risk thrombus-containing lesions in native coronaries in the setting of acute coronary syndromes (ACS). Data were prospectively collected in a multicenter (n = 32) registry of consecutive ACS patients. The study population (n = 126) had mostly (84%) totally occluded vessels.
