Folic acid is essential for DNA synthesis and fetal development, with deficiency linked to anemia, cardiovascular disease and pregnancy complications. The clinical guidelines for women of reproductive age mandate supplementation as a universal preventive treatment regardless of blood folic acid levels; therefore, routine folic acid level testing is not recommended for this population. However, the vast majority of pregnant women do not implement the recommended preventive actions, indicating that new strategies are needed to improve that situation.

Article Synopsis
  • The study aimed to assess if a slower, flexible titration of semaglutide could enhance adherence and minimize gastrointestinal side effects in patients with type 2 diabetes compared to the standard titration method.
  • A total of 104 patients were divided into two groups: one followed the standard dosage increase schedule, while the other had a more gradual dosage increase with the option to pause if gastrointestinal issues arose.
  • Results showed that the flexible group had significantly fewer withdrawals due to adverse events and reported lower levels of nausea and fatigue, while effectiveness in managing diabetes (measured by HbA1c and BMI) remained similar between both groups.

Objective: Lack of insurance coverage, limited access to health services and lower socioeconomic status (SES) are contributors to inadequate utilization of biologic disease modifying anti-rheumatic drugs (bDMARD) in rheumatoid arthritis (RA). The broad national insurance coverage for bDMARDs in Israel provides a unique opportunity to study the impact of SES and geographical location without being biased by the limitation of insurance coverage.

Methods: We identified RA patients using the International Classification of Disease 9th revised codes.

Purpose: Although studies have shown that more temporally regular (TR) primary care visits are associated with improved patient outcomes, none have examined what clinic staff can do to encourage greater TR visits. This study aims to increase understanding of factors related to health care staff dynamics that contribute to more TR primary care visits for adults with chronic health conditions.

Methods: We conducted semistructured interviews with 15 primary care physicians, 12 nurses, 15 administrative staff, and 4 pharmacists at 12 clinics; one-half characterized as high-TR clinics where patients had regular follow-ups, and the other as low-TR clinics.

Pediatric pain significantly affects children's lives, leading to school absenteeism, impaired social interactions, and psychological distress. The perception of sensory signals as pain is influenced by the brain's noradrenergic system, and recent evidence suggests that chronic pain may impact cognitive functioning and emotional regulation. Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with alterations in the dopaminergic/noradrenergic systems, which could affect pain perception.

Article Synopsis
  • This study investigated the effectiveness of serum folic acid testing in children and teens in a developed country without mandatory food fortification, analyzing data from over 20,000 patients aged 0-18 between 2008 and 2018.
  • Out of the patients tested, only 4.3% had folic acid deficiency, and the majority did not show signs of anemia, suggesting low rates of severe deficiency in the population studied.
  • The research highlighted that certain factors, such as male gender, older age, higher BMI, and specific medication usage (like antipsychotics or drugs for ADHD), increased the risk of folic acid deficiency, but routine testing may not be necessary for healthy children in developed countries.

Background: Studies have demonstrated that 50% to 80% of patients do not receive an International Classification of Diseases (ICD) code assigned to their medical encounter or condition. For these patients, their clinical information is mostly recorded as unstructured free-text narrative data in the medical record without standardized coding or extraction of structured data elements. Leumit Health Services (LHS) in collaboration with the Israeli Ministry of Health (MoH) conducted this study using electronic medical records (EMRs) to systematically extract meaningful clinical information about people with diabetes from the unstructured free-text notes.
