Early life stress and pubertal predictors of subsequent substance use in a national diverse sample of adolescents: Sex and substance type matter.

Background: Early life stress (ELS) increases the risk of substance use disorder (SUD) in adulthood. The pathway from ELS to SUD is hypothesized to be influenced by sex. We examine the impact of ELS on adolescent first substance use, a common precursor to adult SUDs, and test for sex differences in the relationship between ELS and risk of first use of alcohol, nicotine, and marijuana.

Hepatic steatosis induced by nicotine plus Coca-Cola™ is prevented by nicotinamide riboside (NR).

Introduction: Cigarettes containing nicotine (Nic) are a risk factor for the development of cardiovascular and metabolic diseases. We reported that Nic delivered via injections or e-cigarette vapor led to hepatic steatosis in mice fed with a high-fat diet. High-fructose corn syrup (HFCS) is the main sweetener in sugar-sweetened beverages (SSBs) in the US.

Neuroendocrine mechanisms in the links between early life stress, affect, and youth substance use: A conceptual model for the study of sex and gender differences.

Early life stress (ELS) is defined as an acute or chronic stressor that negatively impacts a child's development. ELS is associated with substance use and mental health problems. This narrative literature review focuses on sex and gender differences in the effects of ELS on 1) adolescent neuroendocrine development; 2) pubertal brain maturation; and 3) development of internalizing symptoms and subsequent substance use.

Implementation of Specialty Tobacco Use Disorder Services in a Community Health Setting: Support for Enhanced Prescription Practices.

Objectives: Although public efforts to reduce tobacco use have been successful, millions of US adults currently smoke tobacco. Reducing the public health burden of tobacco use disorder (TUD) and eliminating disparities experienced by underresourced communities requires increased accessibility to services. The goal of this study was to assess whether prescriptions for evidence-based medications for tobacco treatment showed steeper growth rates among community health clinics providing specialty TUD services as compared with treatment as usual.

The lipolysis inhibitor acipimox reverses the cardiac phenotype induced by electronic cigarettes.

Electronic cigarettes (e-cigarettes) are a prevalent alternative to conventional nicotine cigarettes among smokers and people who have never smoked. Increased concentrations of serum free fatty acids (FFAs) are crucial in generating lipotoxicity. We studied the effects of acipimox, an antilipolytic drug, on e-cigarette-induced cardiac dysfunction.

The role of Neurochemicals, Stress Hormones and Immune System in the Positive Feedback Loops between Diabetes, Obesity and Depression.

Type 2 diabetes mellitus (T2DM) and depression are significant public health and socioeconomic issues. They commonly co-occur, with T2DM occurring in 11.3% of the US population, while depression has a prevalence of about 9%, with higher rates among youths.

Fatty Acid Excess Dysregulates CARF to Initiate the Development of Hepatic Steatosis.

CARF (CDKN2AIP) regulates cellular fate in response to various stresses. However, its role in metabolic stress is unknown. We found that fatty livers from mice exhibit low CARF expression.

Racial/ethnic and gender disparity in the severity of NAFLD among people with diabetes or prediabetes.

Non-alcoholic fatty liver disease (NAFLD) exhibits a racial disparity. We examined the prevalence and the association between race, gender, and NAFLD among prediabetes and diabetes populations among adults in the United States. We analyzed data for 3,190 individuals ≥18 years old from the National Health and Nutrition Examination Survey (NHANES) 2017-2018.

Electronic Cigarette Use and the Risk of Cardiovascular Diseases.

Electronic cigarettes or e-cigarettes are the most frequently used tobacco product among adolescents. Despite the widespread use of e-cigarettes and the known detrimental cardiac consequences of nicotine, the effects of e-cigarettes on the cardiovascular system are not well-known. Several and studies delineating the mechanisms of the impact of e-cigarettes on the cardiovascular system have been published.

A New Ingenious Enemy: Heat-Not-Burn Products.

While cigarette smoking is still a major source of morbidity and mortality, e-cigarette usage is skyrocketing, and the tobacco industry is finding new ways to market nicotine. With updated published research highlighting the dangers of cigarette smoking and now vaping, the industry has been developing new techniques and devices that circumvent this research to hook users on tobacco and nicotine. The FDA allowed Philip Morris International (PMI) to sell their heat not burn tobacco products known as iQOS in 2019.

Embedding comprehensive smoking cessation programs into community clinics: study protocol for a cluster-randomized controlled trial.

Background: Cigarette smoking among adults in the USA is a leading cause of preventable death worldwide, even though there has been a decline in prevalence since 2005. The addictive nature of nicotine is the chief reason smokers continue to use tobacco. Although the majority of smokers report a desire to quit smoking, a small minority who attempt to quit achieve long-term cessation.

Sex-Specific Differences in the Association Between Race/Ethnicity and NAFLD Among US Population.

Non-alcoholic fatty liver disease (NAFLD) is spreading worldwide, with a racial/ethnic disparity. We examined the gender role in the racial/ethnic difference in NAFLD in the US population. We analyzed data for 3,292 individuals ≥18 years old from NHANES 2017-2018, a representative sample of the non-institutionalized adult population in the US.

US Tobacco 21 is Paving the Way for a Tobacco Endgame.

The battle against tobacco usage is being fought on all fronts. On December 19, 2019, a measure to raise the minimum age to buy tobacco products to 21 from 18 was passed by the United States Congress and signed by President Donald Trump. This instated banning the sale of all tobacco products and electronic cigarettes to anyone in the US under the age of 21.

Safety Net Provider Attitudes Toward Smoking Cessation Treatment.

Cigarette smoking, which poses significant health risks, is prevalent among vulnerable populations commonly treated by safety net providers. A large-scale implementation science project on specialty tobacco use treatment was launched within the Los Angeles County Health Agency. The first phase of this study seeks to summarize and compare smoking cessation treatment attitudes of providers at the Department of Health Services (DHS) and Department of Mental Health (DMH).

Implementing texting programs in the P.O.W.E.R. (preventing obesity with eating right) medical group visit for weight loss.

Background: The effect of incorporating mobile technology to support participants' lifestyle change and weight loss in medical group visits has not been well studied in a safety-net setting.

Rationale And Design: Thus, the rationale of the current study was to examine the effect of text messaging in a medical group visit, and test the effect of two texting programs (12 weeks and 20 weeks), compared to those who did not receive text-messaging in the Preventing Obesity With Eating Right (POWER) group visit program. The primary outcome was weight loss.

Reassessment of the Hispanic Disparity: Hepatic Steatosis Is More Prevalent in Mexican Americans Than Other Hispanics.

Hepatic steatosis (HS) is a growing problem in adults worldwide, with racial/ethnic disparity in the prevalence of the disease. The purpose of this study was to characterize the racial/ethnic prevalence of the stages (normal/mild [S0/S1], moderate [S2], and severe [S3]) of HS in Mexican Americans and other Hispanics compared to other racial/ethnic groups. We analyzed data for 5,492 individuals 12 years and older from the newly released National Health and Nutrition Examination Survey 2017-2018, which is a representative sample of the US adult population.

Unhealthy Lifestyle and Gut Dysbiosis: A Better Understanding of the Effects of Poor Diet and Nicotine on the Intestinal Microbiome.

The study of the intestinal or gut microbiome is a newer field that is rapidly gaining attention. Bidirectional communication between gut microbes and the host can impact numerous biological systems regulating immunity and metabolism to either promote or negatively impact the host's health. Habitual routines, dietary choices, socioeconomic status, education, host genetics, medical care and environmental factors can all contribute to the composition of an individual's microbiome.

Metabolic parameters in smokers undergoing smoking reduction.

Introduction: Few human studies have explored the mechanisms of smoking-induced insulin resistance. : To prospectively examine the metabolic changes of smoking reduction.

Methods: Cigarette smokers (n = 22; ½-2 packs per day) were enrolled in a smoking reduction program (counseling plus bupropion × 8 weeks; Phase I) followed by monitoring only (no counseling or bupropion × 16 weeks; Phase II).

The Combination of High-Fat Diet and Oral Marijuana Promotes the Development of Fibrosis in the Mouse Corpora Cavernosa.

Introduction: The link between cannabis use and erectile dysfunction remains unclear. Moreover, the effect of cannabis in tandem with current Western dietary habits is an area in male sexual health that has yet to be explored. This study seeks to investigate the impact of diet and cannabis on penile health in an animal model.

Adverse effects of fetal exposure of electronic-cigarettes and high-fat diet on male neonatal hearts.

Epidemiological studies have shown an increased risk of cardiovascular diseases in children born to mothers who smoked during pregnancy. The cardiovascular risk in the offspring associated with in utero nicotine exposure is further exaggerated by maternal obesity. The consumption of electronic cigarettes (e-cigarettes) is alarmingly increasing among adolescents and young adults without the knowledge of their harmful health effects.

High Prevalence of Adrenal Remnant Tissue in Patients Undergoing Bilateral Adrenalectomy for Cushing's Disease.

Bilateral adrenalectomy (BLA) is a treatment option for patients with Cushing's Disease (CD) if transsphenoidal pituitary surgery fails or is not a therapeutic option. For most patients, BLA eliminates endogenous glucocorticoid and mineralocorticoid production, but for a small number of patients, endogenous secretion of adrenal hormones from adrenal tissue continues or recurs, leading to signs and symptoms of hypercortisolism. If adrenal tissue is confined to the adrenal bed, it is considered , while if it is outside the adrenal bed, it is considered .

Electronic cigarettes cause alteration in cardiac structure and function in diet-induced obese mice.

In spite of the widespread use of electronic cigarettes, also known as e-cigarettes, and the proposed adverse cardiac effects of nicotine, the detrimental effects of e-cigarettes on the heart are not well known. This study examines the detrimental effects of e-cigarettes with nicotine at doses that yield circulating nicotine and cotinine in the ranges similar to the levels found in habitual smokers, and a high fat diet (HFD) on cardiac structure and function in a commonly used model of diet-induced obesity (DIO). C57BL/6J mice on an HFD were exposed to e-cigarette in the presence (2.

Prevalence and Predictors of Nonalcoholic Steatohepatitis Using Multiple Non-Invasive Methods: Data from NHANES III.

Objective: Patients with nonalcoholic steatohepatitis (NASH) are at risk for developing cirrhosis and hepatic cancer. Currently, the definitive gold-standard method of diagnosing NASH is a liver biopsy, an invasive and costly method. Our objective was to compare three non-invasive methods of identifying NASH by using data on 10,007 subjects from NHANES III (1988-1994) to determine the prevalence and variables associated with NASH, as defined by each non-invasive method.
