Background: Both glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and continuous glucose monitoring (CGM) have been shown to improve glycated hemoglobin A1c (A1c) levels among patients with type 2 diabetes mellitus (T2DM). Recently, a US real-world study found statistically significant improvements in A1c levels among patients using GLP-1 RA and a CGM device, compared with a matched cohort receiving only GLP-1 RA.

Objectives: To assess the cost-effectiveness from a US payer perspective of initiating CGM (FreeStyle Libre Systems) in people living with T2DM using a GLP-1 RA therapy, compared with GLP-1 RA alone.

Introduction: For people living with diabetes, effective glucose monitoring is a key component in diabetes care, helping to reduce disease burden, complications, and healthcare utilization. Sensor-based glucose monitoring systems, which can provide more comprehensive information about glucose levels than capillary-based self-monitoring of blood glucose (SMBG), are becoming established among people living with diabetes. The objective of this study was to assess the cost-effectiveness of glucose monitoring with FreeStyle Libre systems, compared with SMBG, from the perspective of a Canadian private payer.

Background: Reducing the risks of complications is a primary goal of diabetes management, with effective glycemic control a key factor. Glucose monitoring using continuous glucose monitoring (CGM) technology is an important part of diabetes self-management, helping patients reach and maintain targeted glucose and glycated hemoglobin (HbA1c) levels. Although clinical guidelines recommended CGM use, coverage by Medicaid is limited, likely because of cost concerns.

Diabetic ketoacidosis (DKA) is a life-threatening complication, which is most common in individuals with type 1 diabetes (T1D) and is a significant risk for morbidity and mortality, and it is an economic burden on individuals, health care systems, and payers. Younger children, minority ethnic groups, and those with limited insurance are at the greatest risk for presentation of DKA at T1D diagnosis. Although monitoring ketone levels is an essential part of acute illness management and for both early detection and prevention of a DKA episode, studies have reported poor adherence to ketone monitoring.

Membrane application is widespread in water filtration to remove natural organic matter (NOM), especially humic acid. However, there is a significant concern in membrane filtration, which is fouling, which will cause a reduction in the membrane life span, a high energy requirement, and a loss in product quality. Therefore, the effect of a TiO/PES mixed matrix membrane on different concentrations of TiO photocatalyst and different durations of UV irradiation was studied in removing humic acid to determine the anti-fouling and self-cleaning effects.

Peritoneal metastases are frequently found in high-grade serous carcinoma (HGSOC) patients and are commonly associated with a poor prognosis. The tumor microenvironment (TME) is a complex milieu that plays a critical role in epigenetic alterations driving tumor development and metastatic progression. However, the impact of epigenetic alterations on metastatic ovarian cancer cells in the harsh peritoneal microenvironment remains incompletely understood.

Spinal anesthesia is generally accepted as an effective and safe practice. Three rare incidents of postoperative cerebral infarction after surgery under spinal anesthesia prompted us to assess whether spinal bupivacaine may compromise carotid or cerebral blood flow. Postoperative examination after the stroke incident revealed that all three patients shared a common pathology of stenosis or atheromatosis in the carotid or middle cerebral artery.

Article Synopsis
  • Adductor canal block (ACB) is becoming popular for pain management after total knee arthroplasty (TKA), but recent studies question its effectiveness and timing for optimal results.
  • In a study of 652 TKA patients, those who received ACB (either before or after anesthesia) reported significantly lower pain scores and required fewer opioids compared to the group that didn't receive ACB.
  • Patients without ACB experienced longer hospital stays and more complaints during continuous passive motion training, suggesting ACB may improve overall pain management and recovery post-surgery.

  • Bronchiectasis often coexists with chronic obstructive pulmonary disease (COPD), but the interaction between them is not well understood; this study investigated the clinical influence of COPD on bronchiectasis patients over a 10-year period.
  • The study analyzed 66 patients, where 32% had COPD, revealing that those with COPD had a higher bronchiectasis extent score and reported more frequent sputum production, although the difference was not significant after three years.
  • The findings indicate that while COPD worsens bronchiectasis severity and chronic colonization, it doesn't significantly affect the long-term treatment approaches like inhaled corticosteroids for both groups.

Numerous studies on postoperative nausea and vomiting (PONV) have been carried out since the early days of contemporary surgery. The incidence of PONV has been greatly reduced in recent years and new drugs for PONV keep evolving in the market; however, a substantial number of patients are still under the threat of PONV. Female gender, non-smokers, a history of PONV/motion sickness, and postoperative opioid use are four well-recognized risk factors of PONV.
