OBJECTIVE: To investigate if phentermine treatment induces phentermine abuse, psychological dependence (addiction) or phentermine drug craving in overweight, obese and weight loss maintenance patients. To investigate whether amphetamine-like withdrawal occurs after abrupt cessation of long-term phentermine treatment. DESIGN: Clinical intervention trial with interruption of phentermine treatment in long-term patients. SUBJECTS: 269 obese, overweight or formerly obese subjects (age: 20-88 years, BMI: 21-74 kg m(-2)) treated with phentermine long-term (LTP, N = 117), 1.1-21.1 years, or short-term (ATP, N = 152), 4-22 days, with phentermine doses of 18.75-112.5 (LTP) and 15-93.75 (ATP) mg per day. MEASUREMENTS: Module K of the Mini International Neuropsychiatric Interview modified for phentermine (MINI-SUD), Severity of Dependence Scale (SDS), 45-item Cocaine Craving Questionnaire-NOW (CCQ-NOW) modified for phentermine (PCQ-NOW), and Amphetamine Withdrawal Questionnaire (AWQ) modified for phentermine (PWQ). RESULTS: MINI-SUD interviews were negative for phentermine abuse or psychological dependence in all LTP patients. SDS examination scores were low for all LTP and ATP patients, indicating they were not psychologically dependent upon phentermine. PCQ-NOW scores were low for all LTP and ATP patients, indicating neither short-term nor long-term phentermine treatment had induced phentermine craving. Other than an increase in hunger or eating, amphetamine-like withdrawal symptoms did not occur upon abrupt phentermine cessation as measured by sequential PWQ scores. CONCLUSIONS: Phentermine abuse or psychological dependence (addiction) does not occur in patients treated with phentermine for obesity. Phentermine treatment does not induce phentermine drug craving, a hallmark sign of addiction. Amphetamine-like withdrawal does not occur upon abrupt treatment cessation even at doses much higher than commonly recommended and after treatment durations of up to 21 years.

Hazuda, James O. Hill, Edward S. Horton, Van S. Hubbard, Robert W. Jeffery, Karen C. Johnson, Ruby Johnson, Steven E. Kahn, Anne Kure, Wei Lang, Cora E. Lewis, David M. Nathan, Jennifer Patricio, Anne Peters, Xavier Pi-Sunyer, Henry Pownall, W. Jack Rejeski, Monika Safford, Kerry J. Stewart, Thomas A. Wadden, Michael P. Walkup, Rena R. Wing, Holly Wyatt

Summary: Increased accelerometry-measured moderate-to-vigorous physical activity (MVPA) is associated with decreased risk of cardiovascular disease (CVD) outcomes, emphasizing the need for long-term engagement in MVPA to reduce CVD risk in adults with overweight/obesity and type 2 diabetes.

Sodium Propionate or Sodium Butyrate Promotes Fatty Acid Oxidation in HepG2 Cells Under Oxidative Stress

Kristina. J. J. Cook, Ann Coulter, Michael Keenan, Frank Greenway, Jack. N. N. Losso

Summary: This study evaluated the beneficial effects of sodium butyrate (NaB) and sodium propionate (NaP) on fatty acid oxidation (FAO) genes and proinflammatory cytokine production related to nonalcoholic fatty liver disease (NAFLD). The results showed that NaP and NaB promoted FAO, regulated lipolysis, and reduced reactive oxygen species production in HepG2 cells. NaP and NaB also increased the mRNA expression of key genes related to FAO in different models. Additionally, only NaP treatment significantly decreased tumor necrosis factor alpha (TNF-alpha) expression in LPS-induced HepG2 cells. The findings suggest that NaP and NaB have potential for further in vivo studies on NAFLD.

Serum oxytocin and corticotropin-releasing hormone levels in the third trimester of pregnancy for predicting postpartum depression in Thai women

Awirut Oon-arom, Chawisa Suradom, Somdet Srichairatanakool, Suchaya Luewan, Touchwin Petiwathayakorn, Benchalak Maneeton, Narong Maneeton, Suttipong Kawilapat, Manit Srisurapanont

Summary: This study aimed to determine whether serum oxytocin (OT) or corticotrophin-releasing hormone (CRH) levels in the third trimester of pregnancy could predict postpartum depression (PPD) at six weeks after childbirth. The results showed that only high levels of CRH, not OT, in late pregnancy could predict PPD at six weeks postpartum. However, combining CRH levels, late pregnancy stress, and newborn well-being immediately after birth seems to increase the accuracy of PPD prediction.

Orlistat mouth rinse: Using the tongue to deliver antiobesity medication in a double-blind randomized crossover pilot trial

Summary: This study aimed to investigate the effects of an orlistat mouth rinse on the intake of a high-fat meal. The results showed that the orlistat mouth rinse decreased total and fat calories consumed during the high-fat meal in high-fat consumers, but did not alter calories consumed in low-fat consumers (P < 0.05).

Effect of exercise training on insulin-stimulated glucose disposal: a systematic review and meta-analysis of randomized controlled trials

Summary: This study systematically summarized the effect of exercise training on whole-body insulin sensitivity and found that exercise training significantly increases insulin-stimulated glucose disposal. Weight loss may maximize the effect and improve hepatic insulin sensitivity. Differences in tracer methodology contribute to divergent outcomes and should be considered in research conclusions.

Efficacy and acceptability of vitamin D supplements for depressed patients: A systematic review and meta-analysis of randomized controlled trials

Summary: This systematic review and meta-analysis found that vitamin D supplements were superior to placebo in reducing depressive symptoms, especially in adults with severe depression. Bolus doses of vitamin D appeared to be more effective than daily oral administration. The use of vitamin D supplements did not affect the drop-out rates of depressed patients. Therefore, vitamin D supplements are safe and effective for individuals with depression.

Summary: Naringenin, an activator found in citrus fruits, has beneficial effects on thermogenesis and insulin sensitivity. Our study investigated if carotenoids can enhance the metabolic effects of naringenin on adipocytes. Results showed that beta-carotene acts synergistically with naringenin to improve thermogenesis and glucose metabolism genes.

Convergent Validity of the Edinburgh Postnatal Depression Scale and the Patient Health Questionnaire (PHQ-9) in Pregnant and Postpartum Women: Their Construct Correlations with Functional Disability

Manit Srisurapanont, Awirut Oon-arom, Chawisa Suradom, Suchaya Luewan, Suttipong Kawilapat

Summary: This study aimed to evaluate the convergent validity of the EPDS and PHQ-9 in Thai pregnant and postpartum women, using the WHODAS as the reference standard. The EPDS and PHQ-9 showed moderate correlations with the WHODAS scores in both antenatal and postpartum participants. The PHQ-9 performed better than the EPDS in distinguishing disability from non-disability in postpartum women.

Bioelectrical impedance phase angle is associated with physical performance before but not after simulated multi-stressor military operations

Summary: The physical performance decrements observed during multi-stressor military operations may be attributed to cellular membrane dysfunction, which can be quantified using phase angle (PhA) derived from bioelectrical impedance analysis (BIA). Positive associations between PhA and performance have been reported, but it is unknown whether changes in PhA indicate acute decrements in performance during military operations.

Physiologic hormone administration improves HbA1C in Native Americans with type 2 diabetes: A retrospective study and review of insulin secretion and action

Candida J. Rebello, Tyler S. Morales, Katsya Chuon, Shu Dong, V. Tyrone Lam, Dan Purner, Stanley Lewis, Jonathan Lakey, Robbie A. Beyl, Frank L. Greenway

Summary: Insulin is secreted in pulses to regulate blood glucose levels. In type 2 diabetes, irregularities in insulin secretion occur. Native Americans have a higher prevalence of type 2 diabetes and are genetically predisposed to low beta-cell function. A retrospective chart review of metabolic outcomes in Native Americans showed improvements after physiologic hormone administration, suggesting the need for further investigation in randomized controlled trials.

Summary: This study examined the safety of soybean products in Western diets and conducted a dose-escalating clinical trial in older adults with obesity. The results showed that consuming less than 30g of soybean flour per day is beneficial for cardiovascular and overall health, and can reduce the dependence on other food groups and nutrients in older adults with obesity.
