Lesion loci of impaired affective prosody: A systematic review of evidence from stroke.

Brain Cogn 2021 Jun 9;152:105759. Epub 2021 Jun 9.

Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD 21287, United States; Department of Physical Medicine and Rehabilitation, Johns Hopkins University School of Medicine, Baltimore, MD 21287, United States; Department of Cognitive Science, Krieger School of Arts and Sciences, Johns Hopkins University, Baltimore, MD 21218, United States.

Affective prosody, or the changes in rate, rhythm, pitch, and loudness that convey emotion, has long been implicated as a function of the right hemisphere (RH), yet there is a dearth of literature identifying the specific neural regions associated with its processing. The current systematic review aimed to evaluate the evidence on affective prosody localization in the RH. One hundred and ninety articles from 1970 to February 2020 investigating affective prosody comprehension and production in patients with focal brain damage were identified via database searches.

Consistent Alterations of Human Fecal Microbes after Transplantation into Germ-free Mice.

Genomics Proteomics Bioinformatics 2021 Jun 9. Epub 2021 Jun 9.

MOE Key Laboratory of Molecular Biophysics, Hubei Key Laboratory of Bioinformatics and Molecular-imaging, Department of Bioinformatics and Systems Biology, College of Life Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China; College of Life Science, Henan Normal University, Xinxiang 453007, China. Electronic address:

Fecal microbiota transplantation (FMT) of human fecal samples into germ-free (GF) mice is useful for establishing causal relationships between the gut microbiota and human phenotypes. However, due to the intrinsic differences between human and mouse intestines and the different diets of the two organisms, it may not be possible to replicate human phenotypes in mice through FMT; similarly, treatments that are effective in mouse models may not be effective in humans. In this study, we aimed to identify human gut microbes that undergo significant and consistent changes (i. Read More

Bleeding complications in patients with squamous cell carcinoma of the head and neck.

Head Neck 2021 Jun 12. Epub 2021 Jun 12.

Head and Neck Medical Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy.

Hemorrhage in recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) may be attributed to chemotherapy and local tumor irradiation. Evidence of the relationship between hemorrhage in R/M HNSCC and targeted therapies, including epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) inhibitors, or immune checkpoint inhibitors, is limited. We aimed to identify epidemiological and clinical data related to the occurrence of hemorrhage in R/M HNSCC and to explore its relationship with various therapies. Read More

Risk of Bleeding Associated with Antidepressant Drugs: The Competitive Impact of Antithrombotics in Quantitative Signal Detection.

Drugs Real World Outcomes 2021 Jun 11. Epub 2021 Jun 11.

Department of Psychiatry and Psychotherapy III, University of Ulm, Leimgrubenweg 12-14, 89075, Ulm, Germany.

Background: To date, disproportionality analysis has been unable to demonstrate the increased bleeding risk associated with antidepressant drugs, especially selective serotonin reuptake inhibitors.

Objective: We hypothesised that a potential signal for an increased bleeding risk may be mitigated by the effects of agents other than antidepressant drugs that are strongly associated with haemorrhages, especially antithrombotics. In addition, we investigated if the use of more specific search terms of the Medical Dictionary for Regulatory Activities facilitates the detection of signals. Read More

Revealing the Modular Similarities and Differences Among Alzheimer's Disease, Vascular Dementia, and Parkinson's Disease in Genomic Networks.

Neuromolecular Med 2021 Jun 12. Epub 2021 Jun 12.

Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences, Beijing, China.

Alzheimer's disease (AD), vascular dementia (VD), and Parkinson's disease (PD) exert increasingly lethal or disabling effects on humans, but the associations among these diseases at the molecular level remain unclear. In our research, lists of genes related to these three diseases were acquired from public databases. We constructed gene-gene networks of the lists of disease-related genes using the STRING database and selected the plug-in MCODE as the most suitable method to divide the three disease-associated networks into modules through an entropy calculation.

The Dickkopf1 and FOXM1 positive feedback loop promotes tumor growth in pancreatic and esophageal cancers.

Oncogene 2021 Jun 11. Epub 2021 Jun 11.

Department of Molecular Biology and Biochemistry, Graduate School of Medicine, Osaka University, Suita, Japan.

Dickkopf1 (DKK1) is overexpressed in various cancers and promotes cancer cell proliferation by binding to cytoskeleton-associated protein 4 (CKAP4). However, the mechanisms underlying DKK1 expression are poorly understood. RNA sequence analysis revealed that expression of the transcription factor forkhead box M1 (FOXM1) and its target genes concordantly fluctuated with expression of DKK1 in pancreatic ductal adenocarcinoma (PDAC) cells.

Novel selection paradigms for endovascular stroke treatment in the extended time window.

J Neurol Neurosurg Psychiatry 2021 Jun 11. Epub 2021 Jun 11.

Neurology, Emory University, Atlanta, Georgia, USA

Background And Purpose: The optimal selection methodology for stroke thrombectomy beyond 6 hours remains to be established.

Methods: Review of a prospectively collected database of thrombectomy patients with anterior circulation strokes, adequate CT perfusion (CTP) maps, National Institute of Health Stroke Scale (NIHSS)≥10 and presenting beyond 6 hours from January 2014 to October 2018.

What risks to sustainability are identified throughout care bundle implementation and how can they be addressed? A mixed methods case study.

BMJ Open 2021 Jun 11;11(6):e048815. Epub 2021 Jun 11.

Department of Research and Development, London North West University Healthcare NHS Trust, Harrow, UK.

Objectives: Despite national guidance on how to identify and treat heart failure (HF), variation in HF care persists across UK hospitals. Care bundles have been proposed as a mechanism to deliver reliable optimal care for patients; however, specific challenges to sustain care bundles in practice have been highlighted. With few studies providing insight into how to design or implement care bundles to optimise sustainability, there is little direction for practitioners seeking to ensure long-term impact of their initiatives.

Diet and physical activity in pregnancy to prevent gestational diabetes: a protocol for an individual participant data (IPD) meta-analysis on the differential effects of interventions with economic evaluation.

BMJ Open 2021 Jun 11;11(6):e048119. Epub 2021 Jun 11.

WHO Collaborating Centre for Global Women's Health, Institute of Metabolism and Systems Research, University of Birmingham, Birmingham, UK.

Introduction: Mothers with gestational diabetes mellitus (GDM) are at increased risk of pregnancy-related complications and developing type 2 diabetes after delivery. Diet and physical activity-based interventions may prevent GDM, but variations in populations, interventions and outcomes in primary trials have limited the translation of available evidence into practice. We plan to undertake an individual participant data (IPD) meta-analysis of randomised trials to assess the differential effects and cost-effectiveness of diet and physical activity-based interventions in preventing GDM and its complications.
