FAT4 identified as a potential modifier of orofacial cleft laterality.

Genet Epidemiol 2021 Jun 15. Epub 2021 Jun 15.

Department of Human Genetics, Emory University, Atlanta, Georgia, USA.

Orofacial clefts (OFCs) are common (1 in 700 births) congenital malformations that include a cleft lip (CL) and cleft lip and palate (CLP). These OFC subtypes are also heterogeneous themselves, with the CL occurring on the left, right, or both sides of the upper lip. Unilateral CL and CLP have a 2:1 bias towards left-sided clefts, suggesting a nonrandom process. Read More

Neuroimage Clin 2021 Jun 6;31:102715. Epub 2021 Jun 6.

Department of Neurobiology, Neurology and Geriatrics, Xuanwu Hospital, Capital Medical University, National Clinical Research Center for Geriatric Disease, Beijing, China. Electronic address:

Pinpointing the brain dysconnectivity in idiopathic rapid eye movement sleep behaviour disorder (iRBD) can facilitate preventing the conversion of Parkinson's disease (PD) from prodromal phase. Recent neuroimage investigations reported disruptive brain white matter connectivity in both iRBD and PD, respectively. However, the intrinsic process of the human brain structural network evolving from iRBD to PD still remains largely unknown. Read More

Exome variant discrepancies due to reference genome differences.

Am J Hum Genet 2021 Jun 11. Epub 2021 Jun 11.

Human Genome Sequencing Center, Baylor College of Medicine, Houston, TX 77030, USA. Electronic address:

Despite release of the GRCh38 human reference genome more than seven years ago, GRCh37 remains more widely used by most research and clinical laboratories. To date, no study has quantified the impact of utilizing different reference assemblies for the identification of variants associated with rare and common diseases from large-scale exome-sequencing data. By calling variants on both the GRCh37 and GRCh38 references, we identified single-nucleotide variants (SNVs) and insertion-deletions (indels) in 1,572 exomes from participants with Mendelian diseases and their family members.

Pharmacogenetics-guided advances in antipsychotic treatment.

Clin Pharmacol Ther 2021 Jun 15. Epub 2021 Jun 15.

Campbell Family Mental Health Research Institute, Centre for Addiction and Mental Health, Toronto, ON, Canada.

Pharmacogenetics (PGx) research over the past two decades has produced extensive evidence for the influence of genetic factors on the efficacy and tolerability of antipsychotic treatment. However, the application of these findings to optimize treatment outcomes for patients in clinical practice has been limited. This paper presents a meta-review of key PGx findings related to antipsychotic response and common adverse effects, including antipsychotic-induced weight gain (AIWG), tardive dyskinesia (TD) and clozapine-induced agranulocytosis (CIAG), and highlights advances and challenges in clinical implementation.

C/Can City Engagement Process: An Implementation Framework for Strengthening Cancer Care in Cities in Low- and Middle-Income Countries.

JCO Glob Oncol 2021 Jun;7:901-916

City Cancer Challenge, Geneva, Switzerland.

The effective implementation of locally adapted cancer care solutions in low- and middle-income countries continues to be a challenge in the face of fragmented and inadequately resourced health systems. Consequently, the translation of global cancer care targets to local action for patients has been severely constrained. City Cancer Challenge (C/Can) is leveraging the unique value of cities as enablers in a health systems response to cancer that prioritizes the needs of end users (patients, their caregivers and families, and health care providers).

Palliative Care Nursing Development in the Middle East and Northeast Africa: Lessons From Oman.

J Cancer Educ 2021 Jun 15. Epub 2021 Jun 15.

School of Medicine and College of Nursing, University of Colorado Anschutz Medical Campus, Aurora, CO, USA.

Nurses are on the frontline of palliative care, and in some countries, are the only contact for patients and families facing life-threatening illness. The Oman Cancer Association in the Sultanate of Oman, in collaboration with the Middle Eastern Cancer Consortium and the Oncology Nursing Society, led a palliative care initiative over the past decade to better integrate palliative care into the health care system. Components of this initiative include integrating palliative care into the health care curricula and providing palliative care education to over 400 nurses and other health care professionals within Oman.

Inter-individual body mass variations relate to fractionated functional brain hierarchies.

Commun Biol 2021 Jun 14;4(1):735. Epub 2021 Jun 14.

McConnell Brain Imaging Centre, Montreal Neurological Institute and Hospital, McGill University, Montreal, QC, Canada.

Variations in body mass index (BMI) have been suggested to relate to atypical brain organization, yet connectome-level substrates of BMI and their neurobiological underpinnings remain unclear. Studying 325 healthy young adults, we examined associations between functional connectivity and inter-individual BMI variations. We utilized non-linear connectome manifold learning techniques to represent macroscale functional organization along continuous hierarchical axes that dissociate low level and higher order brain systems.

C-reactive protein is superior to fecal biomarkers for evaluating colon-wide active inflammation in ulcerative colitis.

Sci Rep 2021 Jun 14;11(1):12431. Epub 2021 Jun 14.

First Department of Medicine, Hamamatsu University School of Medicine, Hamamatsu, Shizuoka, Japan.

We evaluated the association between endoscopic scores of colonic inflammation and fecal calprotectin (FC), fecal immunochemical occult blood test (FIT), and C-reactive protein (CRP) in patients with ulcerative colitis (UC). Endoscopic scores reflecting the most severe lesion [maximum Mayo Endoscopic Subscore (M-MES) and Ulcerative Colitis Endoscopic Index of Severity (UCEIS)] and those reflecting the inflammation of the entire colon [sum of MES (S-MES) and Ulcerative Colitis Colonoscopic Index of Severity (UCCIS)] were evaluated. FC, FIT, and CRP were measured, and their association with the four endoscopic scores was evaluated. Read More

Genome-wide association study of phenotypes measuring progression from first cocaine or opioid use to dependence reveals novel risk genes.

Explor Med 2021 28;2:60-73. Epub 2021 Feb 28.

Department of Medicine (Biomedical Genetics), Boston University School of Medicine, Boston, MA 02118, USA.

Aim: Substance use disorders (SUD) result in substantial morbidity and mortality worldwide. Opioids, and to a lesser extent cocaine, contribute to a large percentage of this health burden. Despite their high heritability, few genetic risk loci have been identified for either opioid or cocaine dependence (OD or CD, respectively). Read More

Impact of the Composition of Alcohol/Water Dispersion on the Proton Transport and Morphology of Cast Perfluorinated Sulfonic Acid Ionomer Thin Films.

ACS Omega 2021 Jun 25;6(22):14130-14137. Epub 2021 May 25.

Graduate School of Human and Environmental Studies, Kyoto University, Yoshida nihonmatsu-cho, Sakyo-ku, Kyoto 606-8316, Japan.

The dispersion of perfluorinated sulfonic acid ionomers in catalyst inks is an important factor that controls the performance of catalyst layers in membrane electrode assemblies of polymer electrolyte fuel cells. Herein, the effects of water/alcohol compositions on the morphological properties and proton transport are examined by grazing incidence small-angle X-ray scattering, grazing incidence wide-angle X-ray scattering, and electrochemical impedance spectroscopy. The thin films cast by a high water/alcohol ratio Nafion dispersion have high proton conductivity and well-defined hydrophilic/hydrophobic phase separation, which indicates that the proton conductivity and morphology of the Nafion thin films are strongly influenced by the state of dispersion.

Genome-Wide Association Studies Reveal Susceptibility Loci for Noninfectious Claw Lesions in Holstein Dairy Cattle.

Front Genet 2021 28;12:657375. Epub 2021 May 28.

Animal Science Department, University of California, Davis, Davis, CA, United States.

Sole ulcers (SUs) and white line disease (WLD) are two common noninfectious claw lesions (NICL) that arise due to a compromised horn production and are frequent causes of lameness in dairy cattle, imposing welfare and profitability concerns. Low to moderate heritability estimates of SU and WLD susceptibility indicate that genetic selection could reduce their prevalence. To identify the susceptibility loci for SU, WLD, SU and/or WLD, and any type of noninfectious claw lesion, genome-wide association studies (GWAS) were performed using generalized linear mixed model (GLMM) regression, chunk-based association testing (CBAT), and a random forest (RF) approach.
