Multimodal Biomarkers of Repetitive Head Impacts and Traumatic Encephalopathy Syndrome: A Clinico-Pathological Case Series.

J Neurotrauma 2022 Apr 28. Epub 2022 Apr 28.

University of California San Francisco, Neurology, San Francisco, California, United States;

Traumatic encephalopathy syndrome (TES) criteria were developed to aid diagnosis of chronic traumatic encephalopathy (CTE) pathology during life. Interpreting clinical and biomarker findings in patients with TES during life requires autopsy-based determination of the neuropathological profile. We report a clinico-pathological series of 9 patients with prior repetitive head impacts (RHI) classified retrospectively using the TES research framework (100% male and white/Caucasian, age at death 49-84) who completed antemortem neuropsychological evaluations, T1-weighted MRI, diffusion tensor imaging (N=6), (18)F-fluorodeoxyglucose-PET (N=5), and plasma measurement of neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and total tau (N=8).

Relationship Between Serum Brain-Type Natriuretic Peptide and Biomarkers of Growth in Infants With Shunt-Dependent Single Cardiac Ventricle.

Am J Cardiol 2022 May 11;171:146-150. Epub 2022 Mar 11.

Division of Cardiology, Department of Pediatrics, Children's Hospital of Philadelphia, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pennsylvania.

For infants with shunt-dependent or ductal-dependent single ventricle heart disease, poor growth is common and associated with morbidity and impaired neurodevelopmental outcomes. Although attention has focused on nutrition to promote weight gain, little is known about the relation between heart failure and growth factors. A prospective observational pilot study was performed to assess the relation between heart failure, assessed by brain natriuretic peptide (BNP), and growth factors (insulin-like growth factor 1 [IGF-1] and insulin-like growth factor-binding protein 3) at 3 visits: (1) before discharge from neonatal intervention with the establishment of stable pulmonary blood flow, (2) immediately before superior cavopulmonary connection, and (3) before discharge after superior cavopulmonary connection operation.

Pathophysiology of intraabdominal hypertension and abdominal compartment syndrome and relevance to veterinary critical care.

J Vet Emerg Crit Care (San Antonio) 2022 Jan;32(S1):48-56

Department of Veterinary Clinical Sciences, The Ohio State University, Columbus, Ohio, USA.

Background: Increased intraabdominal pressure, termed intraabdominal hypertension (IAH), is reported as an independent cause of morbidity and mortality in the human ICU but, until recently, has been rarely described in veterinary species outside of experimental models. Failure to identify severe IAH leads to organ dysfunction, termed abdominal compartment syndrome, and rapidly becomes fatal without therapeutic intervention. Although the veterinary community has been slow to address the concept of IAH and associated comorbidities, recent companion and large animal case series and experimental studies suggest IAH may also be common in veterinary species and correlates well with risk factors and grading systems already described in the human literature.

The Five-Factor Model for the Diagnosis of Parental Alienation.

J Am Acad Child Adolesc Psychiatry 2022 May 17;61(5):591-594. Epub 2021 Dec 17.

University of California San Francisco.

Although the phenomenon that we know as parental alienation (PA) had been described in the mental health and legal literature for many years, it was given its name-parental alienation syndrome-by Richard Gardner in 1985. As time went on, most writers abandoned the use of the word syndrome and simply referred to this mental condition as parental alienation. The definition of PA is a mental state in which a child-usually one whose parents are engaged in a high-conflict separation or divorce-allies strongly with one parent (the favored parent) and rejects a relationship with the other parent (the alienated parent) without a good reason.

Percutaneous ultrasound-guided radiofrequency ablation for giant desmoid tumors of the intra-abdominal cavity in a patient with Gardner syndrome.

J Cancer Res Ther 2021 Nov;17(5):1286-1288

Department of Ultrasonography, The Second Affiliated Hospital of Zhejiang University School of Medicine, Zhejiang, China.

Gardner syndrome (GS) is a rare variant of familial adenomatous polyposis, leading to numerous intra- and extracolonic lesions. Extracolonic lesions of GS are most common with desmoid tumors (DTs) in the abdominal wall, intra-abdominal cavity, and mesentery. Surgery remains the primary treatment for DTs; however, the patients are challenged with the high recurrence rate after surgical resection, and wide resection often results in debilitating loss of function.

Recurrent CTNNB1 mutations in craniofacial osteomas.

Mod Pathol 2022 Apr 1;35(4):489-494. Epub 2021 Nov 1.

Division of Translational Pathology, Gerhard-Domagk-Institute of Pathology, University Hospital Münster, Albert-Schweitzer-Campus 1, 48149, Münster, Germany.

Osteoma is a benign bone forming tumor predominantly arising on the surface of craniofacial bones. While the vast majority of osteomas develops sporadically, a small subset of cases is associated with Gardner syndrome, a phenotypic variant of familial adenomatous polyposis caused by mutations in the APC gene resulting in aberrant activation of WNT/β-catenin signaling. In a sequencing analysis on a cohort of sporadic, non-syndromal osteomas, we identified hotspot mutations in the CTNNB1 gene (encoding β-catenin) in 22 of 36 cases (61. Read More

Personality, spatiotemporal ecological variation and resident/explorer movement syndromes in the sleepy lizard.

J Anim Ecol 2022 01 9;91(1):210-223. Epub 2021 Nov 9.

Department of Environmental Science and Policy, University of California, Davis, CA, USA.

Individual variation in movement is profoundly important for fitness and offers key insights into the spatial and temporal dynamics of populations and communities. Nonetheless, individual variation in fine-scale movement behaviours is rarely examined even though animal tracking devices offer the long-term, high-resolution, repeatable data in natural conditions that are ideal for studying this variation. Furthermore, of the few studies that consider individual variation in movement, even fewer also consider the internal traits and environmental factors that drive movement behaviour which are necessary for contextualising individual differences in movement patterns.
