Prevalence of biopsy‐proven non‐alcoholic fatty liver disease in severely obese subjects without metabolic syndrome

This study evaluates the prevalence of NAFLD in severely obese subjects without MS. We retrospectively reviewed 445 charts from our database of severely obese subjects with clinical suspicion of NAFLD and who were selected for laparoscopic Roux‐en‐Y gastric bypass surgery. One hundred five subjects who did not have MS, as defined by the International Diabetes Foundation, based on comprehensive pre‐operative metabolic evaluation were included. Liver biopsy specimens were evaluated for NAFLD. 24% of morbidly obese (mean body mass index [BMI] 48 kg m−2) adult subjects (mean age 38 years) who underwent bariatric surgery did not have MS. NAFLD was identified in 77 (73%) on liver biopsy, out of which 59 (56%) were labelled as FL and 18 (17%) had histological diagnosis of NASH. Age, gender, race and BMI were the same among all groups. Among NAFLD subjects, 22% did not have any additional metabolic component of MS, while 36% had low high‐density lipoprotein, 27% had hypertension, 8% had high triglycerides and 6% had hyperglycaemia. IR calculated by HOMA‐IR (Homeostatic Model Assessment for Insulin Resistance) and diagnosis of hyperglycaemia was statistically higher in NASH group compared to those who did not have NASH. NAFLD is highly prevalent in morbidly obese individuals who undergo bariatric surgery despite the absence of MS. Diagnosis of hyperglycaemia in such subjects suggests the presence of IR and may have underlying NASH, which is a progressive ...

CONCLUSIONS: The prevalence of ESI was 0.13 episodes per year. Poor competency of ES care, catheter mobilization, history of catheter-pulling injury, and mechanical stress by waist belt or the protective bag of PD on ES were risk factors for ESI. PMID: 32072873 [PubMed - in process]

Molecular Mechanisms of Notch Signaling in Lymphoid Cell Lineages Development: NF-κB and Beyond. Adv Exp Med Biol. 2020;1227:145-164 Authors: Tsaouli G, Barbarulo A, Vacca A, Screpanti I, Felli MP Abstract Notch is a ligand-receptor interaction-triggered signaling cascade highly conserved, that influences multiple lineage decisions within the hematopoietic and the immune system. It is a recognized model of intercellular communication that plays an essential role in embryonic as well as in adult immune cell development and homeostasis. Four members belong to the family of Notch receptors (Notch1-4...

Authors: Aradhya R, Jagla K Abstract Notch plays multiple roles both in development and in adult tissue homeostasis. Notch was first identified in Drosophila in which it has then been extensively studied. Among the flag-ship Notch functions we could mention its capacity to keep precursor and stem cells in a nondifferentiated state but also its ability to activate cell proliferation that in some contexts could led to cancer. In general, both these functions involve, canonical, ligand-dependent Notch activation. However, a ligand-independent Notch activation has also been described in a few cellular contexts. Here, w...

Authors: Salviano-Silva A, Berti FCB, Lobo-Alves SC, de Araujo-Souza PS, Boldt ABW, Malheiros D Abstract The Notch signaling is a crucial pathway involved in cellular development, progression, and differentiation. Deregulation of Notch signaling pathway commonly impacts tissue homeostasis, being highly associated with proliferative disorders. The long noncoding RNAs (lncRNAs), which are transcripts with more than 200 nucleotides that do not code for proteins, were already described as Notch signaling pathway-interacting molecules. Many of them act as important transcriptional and posttranscriptional regulators, aff...

Authors: McIntyre B, Asahara T, Alev C Abstract Notch signaling is an evolutionarily conserved pathway associated with the development and differentiation of all metazoans. It is needed for proper germ layer formation and segmentation of the embryo and controls the timing and duration of differentiation events in a dynamic manner. Perturbations of Notch signaling result in blockades of developmental cascades, developmental anomalies, and cancers. An in-depth understanding of Notch signaling is thus required to comprehend the basis of development and cancer, and can be further exploited to understand and direct the ...

Authors: Reichrath J, Reichrath S Abstract Evolutionary conserved Notch signaling is of high importance for embryogenesis and adult tissues, representing one of the most fascinating pathways that regulate key cell fate decisions and other core processes. This chapter gives a short introduction to the first volume of the book entitled Notch Signaling in Embryology and Cancer, that is intended to provide both basic scientists and clinicians who seek today`s clearest understanding of the molecular mechanisms that mediate Notch signaling with an authoritative day-to-day source. On a first look, Notch signaling, that fi...

Authors: Koch TR, Shope TR Abstract Obesity is a major factor in the worldwide rise in the prevalence of type 2 diabetes mellitus. The obesity "epidemic" will require novel, effective interventions to permit both the prevention and treatment of diabetes caused by obesity. Laparoscopic vertical sleeve gastrectomy is a newer bariatric surgical procedure with a lower risk of complications (compared to Roux-en-Y gastric bypass surgery). Based in part on restriction of daily caloric intake, sleeve gastrectomy has a major role in inducing significant weight loss and weight loss is maintained for at least 10&nbs...

The objective of this study was to examine how internalizing and externalizing symptoms mediate the association of ACEs with prescription opioid misuse in order to understand how ACEs interconnect with mental health and substance use problems. Adults aged 18 or older from the National Epidemiological Survey on Alcohol and Related Conditions Wave 3 (NESARC-III) conducted in 2012–2013 were included (N = 36,309). The prescription opioid misuse outcomes examined include prescription opioid misuse status, early-onset status of prescription opioid misuse, frequency of past-year prescription opioid misuse, and opioid us...

Too often I feel like as pre-dentals all we worry about are how high our stats are, how much we impact others, and if getting into dental school is even possible. Our lives revolve around helping others, however what do we do when we need to help ourselves? I've spent the last 4 years of college trying to make a difference in my community; caring about the well-being of others. Recently my father was diagnosed with cancer and I do not know how to cope with it. Mentally I have been... Dealing with adversity...

The aim of the study was to investigate whether interaction of high-fructose diet and chronic stress alter insulin and glucocorticoid signalling thus affecting hepatic glucose homeostasis. High-fructose diet led to hyperinsulinemia, increased glucose transporter 2 level, elevated protein kinase B (Akt) phosphorylation, increas...
