The elements were reacted in an induction furnace and the samples were post-annealed to increase phase purity and crystallinity. The RhCd phases crystallize with the cubic CeCrAl type structure, space group 3̄.

Consensus recommendations for measuring the impact of contraception on the menstrual cycle in contraceptive clinical trials.

Objective: We sought to develop consensus recommendations for measurement and analysis of data on contraceptive-induced menstrual changes (CIMCs) in contraceptive clinical trials. We built upon previous standardization efforts over the last 50 years and prioritized input from a variety of global experts and current regulatory authority guidance on patient-reported outcomes.

Study Design: We completed a formal consensus-building process with an interdisciplinary group of 57 experts from 30 organizations and 14 countries in five global regions who work across academia, nonprofit research organizations, the pharmaceutical industry, and funding agencies.

[Stroke in octogenarians].

Stroke is one of the most common causes of disability in older adults. It remains a common cause of death and permanent functional limitation in individuals who are older than 80 years. Approximately 50% of all strokes occur in people over the age of 75, and 30% in those over 85.

Artificial Intelligence in Transcranial Doppler Ultrasonography.

Transcranial Doppler is an instrumental ultrasound method capable of providing data on various brain pathologies, in particular, the study of cerebral hemodynamics in stroke, quickly, economically, and with repeatability of the data themselves. However, literature reviews from clinical studies and clinical trials reported that it is an operator-dependent method, and the data can be influenced by external factors, such as noise, which may require greater standardization of the parameters. Artificial intelligence can be utilized on transcranial Doppler to increase the accuracy and precision of the data collected while decreasing operator dependencies.

[Arthropathy as the first manifestation of undiagnosed hemochromatosis: a case report on an unusual course].

A 54-year-old man presented with increasing arthralgia and swelling of the metacarpophalangeal (MCP) joints II and III for approximately 2 years. He also reported morning stiffness and joint pain in both knees and feet.Both MCP joints II and III and the proximal interphalangeal joints II and III were tender without visible swelling.

[Vaccination and cardiovascular diseases].

Respiratory tract infections with influenza, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and respiratory syncytial (RS) viruses and pneumococci as well as endogenous reactivation of varicella zoster viruses presenting as herpes zoster, are associated with adverse cardiovascular outcomes, such as myocardial infarction or hospitalization for heart failure. Effective prevention of these events, particularly through influenza and pneumococcal vaccination, is well established and cost-effective. Despite guideline recommendations to vaccinate older patients and people at risk, vaccination rates in these population groups remain suboptimal and below average in international comparison.

[Spontaneous craniocervical dissection].

Performance: Spontaneous dissections of the cerebral arteries are among the leading causes of stroke in young adults. They result from hemorrhage into the outer layers of the arterial wall, which can lead to stenosis or even complete vessel occlusion. Clinical presentations vary, ranging from localized pain to cerebral ischemic complications.

[A short history of stroke].

The history of stroke dates back to antiquity, where it was first described as "apoplexia" in Hippocratic writings. For centuries, understanding of the pathology was limited, based on Galen's theories and humoral pathology. Significant advances were made by Islamic scholars who expanded the knowledge and addressed existing contradictions.

Assessing the Theoretical Efficacy of Combination Therapy Against Gram-Negative Infections in Neutropenic Pediatric Cancer Patients: Insights from the Statistical Analysis of Survey Data.

: Empirical antibacterial therapy for febrile neutropenia reduces mortality due to Gram-negative blood stream infections (BSIs). Pediatric guidelines recommend monotherapy with an antipseudomonal beta-lactam or a carbapenem and to add a second anti-Gram-negative agent in selected situations. We evaluated the changes in the proportions of resistance of beta-lactam monotherapies vs.

A dual experimental-theoretical perspective on ESPT photoacids and their challenges ahead.

Photoacids undergo an increase in acidity upon electronic excitation, enabling excited-state proton transfer (ESPT) reactions. A multitude of compounds that allow ESPT has been identified and integrated in numerous applications, as is outlined by reviewing the rich history of photoacid research reaching back more than 90 years. In particular, achievements together with ambitions and challenges are highlighted from a combined experimental and theoretical perspective.

[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.

Cholesky Decomposition and the Second-Derivative Two-Electron Integrals Required for the Computation of Magnetizabilities Using Gauge-Including Atomic Orbitals.

The computation of magnetizability tensors using gauge-including atomic orbitals is discussed in the context of Cholesky decomposition (CD) for the two-electron repulsion integrals with a focus on the involved doubly differentiated integrals. Three schemes for their handling are suggested: the first exploits the density fitting (DF) aspect of Cholesky decomposition, the second uses expressions obtained by differentiating the CD expression for the unperturbed two-electron integrals, while the third addresses the issue that the first two schemes are not able to represent the doubly differentiated integrals with arbitrary accuracy. This scheme uses a separate Cholesky decomposition for the cross terms in the doubly differentiated two-electron integrals.

Self-Assembled Chains and Solids of Dipolar Atoms in a Multilayer.

We predict that ultracold bosonic dipolar gases, confined within a multilayer geometry, may undergo self-assembling processes, leading to the formation of chain gases and solids. These dipolar chains, with dipoles aligned across different layers, emerge at low densities and resemble phases observed in liquid crystals, such as nematic and smectic phases. We calculate the phase diagram using quantum Monte Carlo methods, introducing a newly devised trial wave function designed for describing the chain gas, where dipoles from different layers form chains without in-plane long-range order.

[Management of acute ischemic stroke : Bridging vs. mothership].

Clinical Issue: Acute ischemic stroke remains one of the most common causes of death in Germany and affects around 16,000 people every year. With the begin of using of i.v.

[Endovascular thrombectomy of medium vessel occlusions].

Background: Acute ischemic stroke is a leading cause of disability and dependency in daily life. While endovascular therapy has become the standard treatment for large vessel occlusions, its benefit for medium vessel occlusions has not yet been clearly established.

Objective: This article provides an overview of the current evidence, epidemiology, and clinical challenges of thrombectomy in distal medium vessel occlusions (DMVOs).

[The use of fracture sonography in midface traumatology].

Ultrasound is today an essential element of otorhinolaryngology. During the course of (technical) development, fracture sonography has also gained increasing clinical and scientific interest. Sonography can already be used today as the imaging method of choice for isolated suspected fractures of the nasal or zygomatic bone.

[Complications of mechanical thrombectomy].

Clinical Problem: Ischemic stroke is the most common cause of disability in adults and an important disease for society; therefore, the prevention, diagnosis, and treatment play an important role. Endovascular mechanical recanalization to reopen large occlusions of the intracerebral vessels has established itself as the gold standard in therapy, which is why knowledge of the most important complications and their management is essential for interventionalists.

Practical Recommendations: Intracranial hemorrhages, which include intracerebral and subarachnoid hemorrhages, are dreaded complications that significantly worsen the clinical outcome.

An Improved Transformation-Associated Recombination Cloning Approach for Direct Capturing of Natural Product Biosynthetic Gene Clusters.

The phylum Actinomycetota and genus Streptomyces in particular are the major source for discovery of natural products with diverse chemical structures and a variety of biological activities. Genes encoding biosynthetic pathways for bacterial natural products are grouped together into biosynthetic gene clusters (BGCs). The size of a typical actinobacterial BGC may range from 10 kb to 200 kb, which makes their cloning for heterologous expression a challenging task.
