Repeated fasting events sensitize enhancers, transcription factor activity and gene expression to support augmented ketogenesis.

Mammals withstand frequent and prolonged fasting periods due to hepatic production of glucose and ketone bodies. Because the fasting response is transcriptionally regulated, we asked whether enhancer dynamics impose a transcriptional program during recurrent fasting and whether this generates effects distinct from a single fasting bout. We found that mice undergoing alternate-day fasting (ADF) respond profoundly differently to a following fasting bout compared to mice first experiencing fasting.

Implications of Patient-Reported Outcome Measures among patients with recently diagnosed type 2 diabetes.

Background: For the past two decades, the assessment of the quality of diabetes care has mostly relied on clinical quality indicators. These have not included Patient-Reported Outcome Measures (PROMs) which provide information on outcomes deemed valuable by patients. We aimed to examine the potential utility of PROMs in type 2 diabetes care and to study the association of PROMs with patients' characteristics and clinical quality indicators.

Differential effects of bariatric surgery and caloric restriction on hepatic one-carbon and fatty acid metabolism.

Weight loss interventions, including dietary changes, pharmacotherapy, or bariatric surgery, prevent many of the adverse consequences of obesity, and may also confer intervention-specific benefits beyond those seen with decreased weight alone. We compared the molecular effects of different interventions on liver metabolism to understand the mechanisms underlying these benefits. Male rats on a high-fat, high-sucrose diet underwent sleeve gastrectomy (SG) or intermittent fasting with caloric restriction (IF-CR), achieving equivalent weight loss.

Longitudinal Adherence to Diabetes Quality Indicators and Cardiac Disease: A Nationwide Population-Based Historical Cohort Study of Patients With Pharmacologically Treated Diabetes.

Background Evidence of the cardiovascular benefits of adherence to quality indicators in diabetes care over a period of years is lacking. Methods and Results We conducted a population-based, historical cohort study of 105 656 people aged 45 to 80 with pharmacologically treated diabetes and who were free of cardiac disease in 2010. Data were retrieved from electronic medical records of the 4 Israeli health maintenance organizations.

Three-Year Outcomes of a Schlemm Canal Microstent (Hydrus Microstent) with Concomitant Phacoemulsification in Open-Angle Glaucoma.

Purpose: HORIZON trials have reported the medium- and long-term outcomes of the Hydrus microstent. However, outside of randomized clinical trials, outcomes beyond 24 months have not been previously reported. Here, we examine the 3-year outcomes of the Hydrus microstent with cataract surgery outside of a randomized clinical trial setting.

Sleeve Gastrectomy Reduces Glycemia but Does Not Affect Cognitive Impairment in Lean 5xFAD Mice.

Obesity and hyperglycemia are risk factors for cognitive decline and for the development of Alzheimer's Disease (AD). Bariatric surgery is an effective treatment for obesity that was shown to improve cognitive decline in obese patients. Bariatric surgery was shown to exert weight loss independent effects on metabolic diseases such as type 2 diabetes.

Independent associations of inter-spousal gaps in age and education with long-term mortality and cancer survival: The Jerusalem Perinatal Study 1964-2016.

Purpose: To identify factors responsible for variation in health among married individuals, we investigated the independent associations of gaps in spousal age and education (or "heterogamy") with all-cause and cause-specific mortality as well as with survival of cancer patients.

Methods: Using over four decades of follow-up data on 36,717 couples from Jerusalem (1964-2016), we compared heterogamous with homogamous couples.

Results: Having a less educated spouse was associated with an increased risk for several outcomes in both genders, such as all-cause mortality in males (hazard ratio [HR] = 1.

Splice-Variant Knock-Out of TGFβ Receptors Perturbates the Proteome of Ovarian Carcinoma Cells.

The aim of this study was to analyze the biological role of different transforming growth factor-β (TGFβ) receptor splice variants in ovarian carcinoma (OC). Specific receptor variant knockouts (KO) were prepared using the CRISPR/Cas9 genome editing system in two OC cell lines, TβRI variant 1 (TβRIv1) KO in ES-2 cells and TβRII variant 1 (TβRIIv1) KO in OVCAR-8 cells. Control and KO cells were compared by proteomic analysis, functional tests, analysis of epithelial-mesenchymal transition (EMT) drivers, and Western blot of signaling proteins.

Bariatric Surgery Affects Plasma Levels of Alanine Aminotransferase Independent of Weight Loss: A Registry-Based Study.

Patients that undergo bariatric surgery experience weight loss and a reduction in the plasma levels of the hepatic enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST). We used the Israeli national bariatric registry, which includes demographic, clinical, and biochemical data on 19,403 patients, of which 1335 patients had two-year follow-up data on ALT, AST, A1C, and BMI, to test the dependence of the reduction in the levels of ALT and AST on weight loss. The data were analyzed using regression models, retrospective matching, and time course analyses.

Sleeve Gastrectomy Is Associated with a Greater Reduction in Plasma Liver Enzymes Than Bypass Surgeries-A Registry-Based Two-Year Follow-Up Analysis.

Bariatric surgeries may lead to an improvement in metabolic fatty liver disease, and a reduction in the levels of the hepatic enzyme Alanine Aminotransferase (ALT). We compared the effects of Sleeve Gastrectomy (SG), Roux en Y Gastric Bypass (RYGB) and One Anastomosis Gastric Bypass (OAGB) on the levels of ALT by analysis of two-year follow-up data from 4980 patients in the Israeli Bariatric Registry that included laboratory tests and demographic information. Pre-operative characteristics of patients, and particularly levels of liver enzymes, were similar across surgery types.

Differential functions of TLE1 and TLE3 depending on a specific phosphorylation site.

Mammalian Transducin-like enhancer of split (TLE) confer global repression of numerous target genes in conjunction with a myriad of DNA-binding repressors. These factors have a major role in the regulation of multiple signal transduction pathways. Evidence have been obtained regarding the possible role of some of these proteins in cancer.

Interdigitation and Ellipsoid Zones Disruption Correlate with Visual Outcomes among Treatment-Naive Patients with Diabetic Macular Edema.

Introduction: We have recently shown that defects in interdigitation and ellipsoid zones (IZ and EZ) can predict response to anti-VEGF therapy in a small group of treatment-naive diabetic macular edema (DME) patients. The aim of the current study is to further evaluate this association in a larger study group of patients over a longer follow-up time.

Methods: Thirty eyes of 30 treatment-naive DME patients were analyzed in this retrospective study.

A new perspective for mitigation of SARS-CoV-2 infection: priming the innate immune system for viral attack.

The course of infection by SARS-CoV-2 frequently includes a long asymptomatic period, followed in some individuals by an immune dysregulation period that may lead to complications and immunopathology-induced death. This course of disease suggests that the virus often evades detection by the innate immune system. We suggest a novel therapeutic approach to mitigate the infection's severity, probability of complications and duration.

Guanine Content of MicroRNAs is Associated with their Tumor- Suppressive and Oncogenic Roles in Lung and Breast Cancers.

Background: microRNAs (miRNAs, miRs) are small noncoding RNAs that negatively regulate gene expression at the post-transcriptional level and fine-tune gene functions. Global repression of miRNAs expression in different types of human tumors, after exposure to cigarette smoke, or to the hormone estrogen, have been shown to be associated with guanine (G) enrichment in the terminal Loops (TLs) of their precursors.

Methods: We integrated the G content of miRNA mature forms and precursor miRNA TLs with their described function in the literature, using the PubMed database.

REDUCTION OF POSTINTRAVITREAL INJECTION PAIN USING ICE: An Open-Label Interventional Randomized Controlled Trial.

Purpose: Intravitreal injections of intraocular therapeutic agents are a common and effective treatment for various retinal pathologies. Patient discomfort related to injection is a potential barrier to treatment. Our aim in this study was to evaluate whether cooling the eye using topical ice compresses before intravitreal injection will reduce pain or bleeding.

Peak Occurrence of Retinal Detachment following Cataract Surgery: A Systematic Review and Pooled Analysis with Internal Validation.

Introduction: Timing of retinal detachment (RD) following cataract surgery is of importance for both diagnostic and prognostic factors. However, results on RD onset-time following cataract surgery have been conflicting.

Method: A systematic pooled analysis of the literature regarding timing of retinal detachment following cataract surgery.

Modulation of mitochondrial functions by xenobiotic-induced microRNA: From environmental sentinel organisms to mammals.

Mitochondria play a crucial role in energetic metabolism, signaling pathways, and overall cell viability. They are in the first line in facing cellular energy requirements in stress conditions, such as in response to xenobiotic exposure. Recently, a novel regulatory key role of microRNAs (miRNAs) in important signaling pathways in mitochondria has been proposed.

Frequency, comprehension and attitudes of physicians towards abbreviations in the medical record.

Aims: Abbreviations are common in the medical record. Their inappropriate use may ultimately lead to patient harm, yet little is known regarding the extent of their use and their comprehension. Our aim was to assess the extent of their use, their comprehension and physicians' attitudes towards them, using ophthalmology consults in a tertiary hospital as a model.

microRNAs Downregulation in Cancer is Associated with Guanine Enrichment in the Terminal Loop Sequences of their Precursors.

Background: microRNAs (miRNAs) are small noncoding segments of RNA that negatively regulate gene expression at the post-transcriptional level and fine-tune gene functions. A global repression in miRNA expression is a phenomenon observed in different types of cancer. In this study we aimed to reveal a possible association of miRNAs downregulation in cancer, with the guanine (G) content in the terminal loop (TL) sequences of their precursors.

A potential microRNA regulation of immune-related genes in invertebrate haemocytes.

Bivalve mollusks have been employed as sentinel organisms in environmental health programs due to their sedentary lifestyle, filter-feeding behavior and their ability to accumulate pathogens or toxin molecules inside tissues. Endocrine disrupting chemicals (EDCs) can be up taken and bioaccumulated, and due to sensibility of mollusks to these EDCs, being able to cause immune alterations. Recently, microRNAs (miRNAs) were shown to be involved in modulation and buffering developmental processes against the effects of environmental alterations and pathogenic microorganisms.

Estrogen Repression of MicroRNAs Is Associated with High Guanine Content in the Terminal Loop Sequences of Their Precursors.

Widespread microRNA (miRNA) repression is a phenomenon observed in mammals after exposure to cigarette smoke and in many types of cancer. A comprehensive reduction in miRNA expression after treatment with the hormone estrogen has also previously been described. Here, we reveal a conserved association of miRNA downregulation after estrogen exposure in zebrafish, mouse, and human breast cancer cell line, with a high guanine content in the terminal loop sequences of their precursors, and offer a possible link between estrogen-related miRNA-adducts formation and carcinogenesis.

Estrogen regulation of gene expression in the teleost fish immune system.

Elucidating the mechanisms of estrogens-induced immunomodulation in teleost fish is of great importance due to the observed worldwide continuing decrease in pristine environments. However, little is know about the immunotoxicological consequences of exposure to these chemicals in fish, or of the mechanisms through which these effects are mediated. In this review, we summarize the results showing estrogens (natural or synthetic) acting through estrogen receptors and regulating specific target genes, also through microRNAs (miRNAs), leading to modulation of the immune functioning.

Relationship between anxiety and medical disorders among compulsory military service candidates between the years 1998-2013.

One of the most common psychiatric diagnoses among adolescents is anxiety disorder. Many of the anxiety symptoms are expressed physiologically, and therefore can mimic other medical conditions. The aim of this study was to examine the association between anxiety disorders and other medical conditions sharing common symptoms with anxiety (MDSCSA: Irritable Bowel Syndrome, asthma, migraine and hyperhidrosis).

A potential role for estrogen in cigarette smoke-induced microRNA alterations and lung cancer.

Alteration in the expression of microRNAs (miRNAs) is associated with oncogenesis and cancer progression. In this review we aim to suggest that elevated levels of estrogens and their metabolites inside the lungs as a result of cigarette smoke exposure can cause widespread repression of miRNA and contribute to lung tumor development. Anti-estrogenic compounds, such as the components of cruciferous vegetables, can attenuate this effect and potentially reduce the risk of lung cancer (LC) among smokers.
