Expression of the immune checkpoint receptor TIGIT in Hodgkin's lymphoma.

BMC Cancer 2018 Dec 4;18(1):1209. Epub 2018 Dec 4.

Department of Pathology, University Medical Center Hamburg-Eppendorf, Martinistr. 52, 20246, Hamburg, Germany.

Hodgkin's lymphoma (HL) is characterized by a high background of inflammatory cells which play an important role for the pathogenesis of the disease. T cell immunoreceptor with Ig and ITIM domains (TIGIT) is an inhibitory immune checkpoint receptor and a putative target for novel immunotherapies. To study patterns of TIGIT expression in the T cell background surrounding malignant cells including Hodgkin cells, Reed-Sternberg cells and histiocytic cells, a microenvironment (ME) tissue microarray (TMA) was constructed from tissue punches measuring 2 mm in diameter obtained from formalin-fixed tissue samples of Hodgkin's lymphoma lymph nodes (n = 40) and normal human tonsil (n = 2).

Biomolecules 2018 Nov 19;8(4). Epub 2018 Nov 19.

Department of Internal Medicine II, Ulm University, Albert-Einstein-Allee 23, D-89081 Ulm, Germany.

Patients with inherited dilated cardiomyopathy (DCM) often suffer from severe heart failure based on impaired cardiac contractility leading to increased morbidity and mortality. Integrin-linked kinase (ILK) as a part of the cardiac mechanical stretch sensor was found to be an essential genetic regulator of cardiac contractility. Integrin-linked kinase localizes to z-disks and costameres in vertebrate hearts and regulates the activity of the signaling molecule protein kinase B (PKB/Akt) by controlling its phosphorylation.

Hair cortisol concentration in mothers and their children: roles of maternal sensitivity and child symptoms of attention-deficit/hyperactivity disorder.

J Neural Transm (Vienna) 2018 Oct 29. Epub 2018 Oct 29.

Department of Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy, Philipps-University of Marburg, Hans Sachs Str. 6, 35039, Marburg, Germany.

Associations between mothers' and children's cortisol secretion parameters are well established. According to the bio-behavioral synchrony model, these associations reflect influences of the mother-child relationship, the child's social adjustment, and might also reflect shared genetic dispositions. From the bio-behavioral synchrony model, we predicted a stronger mother-child hair cortisol concentration (HCC) link in mothers showing highly adequate (compared to those showing less adequate) parenting behaviors and in children showing low (compared to those showing high) ADHD symptoms.

A Tool for Connection: Using the Person-of-the-Therapist Training (POTT) Model in Emotionally Focused Couple Therapy Supervision.

J Marital Fam Ther 2018 Aug 13. Epub 2018 Aug 13.

Alliant International University.

Emotionally Focused Couple Therapy (EFT) was developed based on the premise that couples get stuck in negative cycles fueled by their underlying primary emotions and unmet attachment needs (Johnson [2004], Creating connection: The practice of Emotionally Focused Couple Therapy). EFT therapists need to stay in touch with and regulate their own emotions when the tension rises in the sessions, while still staying open and vulnerable to their clients. Person-of-the-Therapist Training model (Aponte & Kissil [2016], The person of the therapist training model: Mastering the use of self) aims to increase therapists' understanding, awareness, and acceptance of their own personal issues to create a more empathic connection with their clients.

J Mol Cell Cardiol 2018 Jul 8;120:42-52. Epub 2018 May 8.

Department of Internal Medicine II, Ulm University Medical Center, Ulm, Germany. Electronic address:

The genetic underpinnings that orchestrate the vertebrate heart rate are not fully understood yet, but of high clinical importance, since diseases of cardiac impulse formation and propagation are common and severe human arrhythmias. To identify novel regulators of the vertebrate heart rate, we deciphered the pathogenesis of the bradycardia in the homozygous zebrafish mutant hiphop (hip) and identified a missense-mutation (N851K) in Na/K-ATPase α1-subunit (atp1a1a.1).

Genetic Regulation of PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) Plasma Levels and Its Impact on Atherosclerotic Vascular Disease Phenotypes.

Circ Genom Precis Med 2018 May;11(5):e001992

Institute for Medical Informatics, Statistics and Epidemiology, Leipzig, Germany (J.P., K.H., H.K., M.L., M.S.)

Background: Inhibition of PCSK9 (proprotein convertase subtilisin/kexin type 9) is a novel strategy to treat hypercholesterolemia and reduce cardiovascular events. However, the potential role of circulating plasma PCSK9 concentrations as a diagnostic and predictive biomarker remains uncertain as of now. Here, we aimed to identify genetic variants associated with plasma PCSK9 and investigate possible causal effects on atherosclerotic vascular disease phenotypes. Read More

Hemi-Hamate Autograft Arthroplasty for the Proximal Interphalangeal Joint Revisited: A New Surgical Approach.

J Hand Surg Asian Pac Vol 2018 Jun;23(2):297-301

‡ Department of Plastic Surgery, Erasmus MC, Rotterdam, The Netherlands.

The hemi-hamate arthroplasty for proximal interphalangeal joint (PIPJ) dorsal fracture dislocations relies on complete dislocation of the joint using the 'shotgun' approach which provides excellent exposure but damages the delicate intrinsic joint stabilisers. We present a new approach to the PIPJ when performing the hemi-hamate arthroplasty. The volar surgical approach involves freeing up the whole tendon sheath-periosteal unit as a single layer, and retracting this to one side. Read More

Not quite Pott's puffy tumour.

BMJ Case Rep 2018 Apr 25;2018. Epub 2018 Apr 25.

Department of Otolaryngology, Ninewells Hospital and Medical School, NHS Tayside, Dundee, Scotland, UK.

Pott's puffy tumour (PPT) is characterised by a subperiosteal abscess associated with osteomyelitis of the frontal bone-a rare complication of frontal sinusitis, more common in the paediatric population. We describe a case mimicking PPT, where abscess extension was facilitated by previous surgery. Usually patients with PPT would be systemically unwell, but our patient, a 63-year-old Caucasian man, was systemically well with a large swelling of his forehead. Read More

Impact of genetically modified organisms on aquatic environments: Review of available data for the risk assessment.

Sci Total Environ 2018 Sep 24;635:687-698. Epub 2018 Apr 24.

Institute for Environmental Sciences, University of Koblenz-Landau, Fortstrasse 7, 76829 Landau, Germany.

The aquatic environment is strongly connected to the surrounding agricultural landscapes, which regularly serve as sources of stressors such as agrochemicals. Genetically modified crops, which are cultivated on a large scale in many countries, may also act as stressors. Despite the commercial use of genetically modified organisms (GMOs) for over 20years, their impact on the aquatic environment came into focus only 10years ago. Read More

[Osteoarticular tuberculosis nosology and diagnostic pitfalls].

Rev Med Liege 2018 Apr;73(4):191-196

Service de Médecine interne générale, CHR Citadelle, Liège, Belgique.

Osteoarticular or skeletal tuberculosis is a clinical manifestation of extrapulmonary tuberculosis, occurring during the lympho-hematogenous spread of Mycobacterium tuberculosis from a pulmonary primary infection or reactivation of latent infection, years or even decades after the initial infection. Bone and joint tuberculosis is a rare disease with non-specific symptoms and radiological characteristics, often delaying diagnosis for more than a year after clinical onset. First-line hospital departments should develop a clinical suspicion when confronted with a subacute inflammatory bone or joint pathology in patients with underlying comorbidities, especially when coming from tuberculosis-endemic countries.

Response of aquatic macrophyte biomass to limnological changes under water level fluctuation in tropical reservoirs.

Braz J Biol 2018 Mar 12. Epub 2018 Mar 12.

Departamento de Botânica, Universidade Federal Rural de Pernambuco - UFRPE, CEP 52171-900, Recife, PE, Brasil.

We evaluated the response of the biomass of aquatic macrophytes under limnological changes after water level fluctuation (WLF) of two tropical reservoirs (R1 and R2), located in northeastern Brazil. Initially we tested the hypothesis that post-WLF limnological conditions and biomass of macrophytes increase or decrease, depending on the variable or species. We monitored a 4 × 50 m permanent plot, in four expeditions per period (pre- or post-WLF), assessing species biomass and 10 limnological variables. Read More
