AI Article Synopsis
- The systematic review investigates the impacts of intermittent energy restriction (IER) and periodic fasting (PF) on metabolic control in patients with type 2 diabetes (T2D), focusing on their effectiveness in managing glucose levels and medication needs.
- The review included 13 studies, finding that both IER and PF diets were effective in reducing glycated hemoglobin (HbA1c) and fasting glucose in some cases, though benefits were typically not sustained long-term.
- Overall, the findings indicate that while IER and PF may help improve glucose regulation in the short term for T2D patients, there is still a significant risk of bias in the available studies and a lack of long-term data.
Article Abstract
Context: The effectiveness of intermittent energy restriction (IER) and periodic fasting (PF) in the management of type 2 diabetes (T2D) remains a subject of discussion.
Objective: The aim of this systematic review is to summarize current knowledge of the effects of IER and PF in patients with T2D on markers of metabolic control and the need for glucose-lowering medication.
Data Sources: PubMed, Embase, Emcare, Web of Science, Cochrane Library, CENTRAL, Academic Search Premier, Science Direct, Google Scholar, Wiley Online Library, and LWW Health Library were searched for eligible articles on March 20, 2018 (last update performed November 11, 2022). Studies that evaluated the effects of IER or PF diets in adult patients with T2D were included.
Data Extraction: This systematic review is reported according to PRISMA guidelines. Risk of bias was assessed through the Cochrane risk of bias tool. The search identified 692 unique records. Thirteen original studies were included.
Data Analysis: A qualitative synthesis of the results was constructed because the studies differed widely in terms of dietary interventions, study design, and study duration. Glycated hemoglobin (HbA1c) declined in response to IER or PF in 5 of 10 studies, and fasting glucose declined in 5 of 7 studies. In 4 studies, the dosage of glucose-lowering medication could be reduced during IER or PF. Two studies evaluated long-term effects (≥1 year after ending the intervention). The benefits to HbA1c or fasting glucose were generally not sustained over the long term. There are a limited number of studies on IER and PF interventions in patients with T2D. Most were judged to have at least some risk of bias.
Conclusion: The results of this systematic review suggest that IER and PF can improve glucose regulation in patients with T2D, at least in the short term. Moreover, these diets may allow for dosage reduction of glucose-lowering medication.

Importance: Endocrine treatments, such as Tamoxifen (TAM) and/or Aromatase inhibitors (AI), are the adjuvant therapy of choice for hormone-receptor positive breast cancer. These agents are associated with menopausal symptoms, adversely affecting drug compliance. Topical estrogen (TE) has been proposed for symptom management, given its' local application and presumed reduced bioavailability, however its oncological safety remains uncertain.

Background: Excisional hemorrhoidectomy and stapled hemorrhoidopexy are 2 common procedures for treating symptomatic hemorrhoids. However, concerns persist regarding the risk of postoperative complications and their unclear prevalence in the literature. This systematic review aims to evaluate and compare the prevalence of incontinence after stapled hemorrhoidopexy and excisional hemorrhoidectomy.

Background: In patients with advanced hepatocellular carcinoma (HCC) following sorafenib failure, regorafenib has been used as an initial second-line drug. It is unclear the real efficacy and safety of sorafenib-regorafenib sequential therapy compared to placebo or other treatment (cabozantinib or nivolumab or placebo) in advanced HCC.

Department of Cardiovascular Medicine, the Affiliated Traditional Chinese Medicine Hospital, Southwest Medical University, Luzhou, China.
Background: Parkinson's disease is a progressive neurodegenerative disease and the care burden in informal caregivers is huge. Summarizing factors associated with the informal caregivers burden can improve our understanding of providing proactive support to informal caregivers caring for patients with Parkinson's disease (PwP) at risk, and provides evidence for clinical practice.
Methods: PRISMA guidelines were followed in this systematic review.
