Article Synopsis
  • Crohn's disease perianal fistulae often don't respond well to standard therapies, but mesenchymal stem cell (MSC)-derived exosomes have shown potential as a treatment, being deemed safe in previous studies.
  • A phase II clinical trial was conducted with 23 patients suffering from refractory perianal fistulas, where exosomes were injected directly into the fistula tracts over a period of 6 months.
  • Results indicated that 60% of patients achieved complete fistula closure, and overall, 69.7% of treated fistula tracts showed significant closure, along with some observed improvements in discharge from the tracts.

Purpose: Colorectal cancer is the second leading cause of cancer death worldwide. Standard treatments for locally advanced rectal cancer include neoadjuvant chemoradiotherapy and total mesorectal excision (TME), which are associated with significant morbidity. After neoadjuvant therapy, one-third of patients achieve a pathological complete response (pCR) and are eligible for a watch-and-wait approach without TME.

  • Persistent high blood sugar levels significantly increase the risk of cognitive disorders in older adults with diabetes, as both type 1 and type 2 diabetes are linked to cognitive impairment.
  • A study involving 1,533 older adults showed that 45.2% experienced cognitive impairment, with higher average hemoglobin A1C and blood glucose levels in those affected.
  • Analysis revealed that diabetes was associated with a 48% higher likelihood of cognitive impairment, particularly in older individuals, women, and those with other health issues like high blood pressure.

  • Frailty is a complex condition in older adults that makes them more vulnerable to stress, and metabolomics studies can help us understand its underlying mechanisms.
  • A systematic review analyzed 21 studies that evaluated the metabolomics profile of frail individuals, highlighting significant differences in metabolite levels compared to healthier subjects.
  • Key findings included lower levels of branched-chain amino acids and carnitine, along with higher levels of glutamate and glutamine in frail individuals, indicating a complex biochemical relationship that could help expand our understanding of frailty.

Article Synopsis
  • - This study aimed to compare the effectiveness of two Letrozole regimens against methotrexate in treating ectopic pregnancy among 88 women with low beta-human chorionic gonadotropin levels.
  • - Participants were divided into three groups: methotrexate, 5-day Letrozole, and 10-day Letrozole, with treatment response assessed by achieving a negative serum beta level without further treatment or surgery.
  • - Results showed that the treatment response rates were similar across all groups (76.7% for methotrexate, 75.0% for 5-day Letrozole, and 90.5% for 10-day Letrozole), indicating no significant differences, and only a small

Article Synopsis
  • Small bowel obstruction (SBO) is a frequent reason for acute abdominal pain in emergency settings, but a definitive diagnostic method is still unclear.
  • This systematic review evaluated 21 studies with nearly 2,000 patients to determine how accurate ultrasonography is for diagnosing SBO, using comprehensive statistical analysis.
  • The results indicate ultrasonography has a high sensitivity (93%) and good specificity (80%) for SBO diagnosis, suggesting it is a promising tool, though further global studies are needed to reinforce these findings.

Addressing the increasing drug resistance in pathogenic microbes, a significant threat to public health, calls for the development of innovative antibacterial agents with versatile capabilities. To enhance the antimicrobial activity of non-toxic biomaterials in this regard, this study focuses on novel, cost-effective chitosan (CS)-based hydrogels, crosslinked using gelatin (GEL), formaldehyde, and metallic salts (Ag, Cu, and Zn). These hydrogels are formed by mixing CS and GEL with formaldehyde, creating iminium ion crosslinks with metallic salts without hazardous crosslinkers.

Background: Pelvic organ prolapse is a debilitating condition impacting lives of millions of women worldwide. Sacrocolpopexy (SCP) is considered an effective and durable surgical technique for treatment of apical prolapse. The aim of this study was to compare short-term outcomes including postoperative complications and unanticipated healthcare encounters between patients who underwent SCP with a mini-laparotomy approach compared to patients treated with laparoscopic and robotic-assisted laparoscopic SCP.

Background: Being considered a life-threatening condition, cesarean scar pregnancy (CSP) leads to loss of fertility, severe bleeding, and even maternal mortality. We intended to assess the effect of double-balloon cervical ripening catheter insertion on CSP termination before nine weeks of gestation.

Method: All participants were diagnosed CSP by abdominal and transvaginal ultrasound The cases were treated with a sterile, double-balloon cervical ripening catheter inserted with real-time transabdominal ultrasound guidance and removed three days later.

Objective: The objective of this study was to evaluate the effectiveness of structured workshops in improving the knowledge and skills of obstetrics and gynecology residents for repairing high-grade perineal lacerations.

Materials And Methods: This quasi-experimental multicenter study evaluated the baseline knowledge of obstetrics and gynecology residents using an online patient-management problem (PMP) tool. After the initial evaluation, a workshop was conducted using sponge models to teach the practical technique for repairing high-grade perineal lacerations, including external and internal anal sphincter repair.

Objectives: To evaluate the effectiveness of the first-line medical management with Methotrexate (MTX) in the treatment of patients with stable tubal Ectopic Pregnancies (EPs) and varying ranges of Beta-Human Chorionic Gonadotropin (β-HCG) levels.

Materials And Methods: In this retrospective cohort study, we reviewed the medical records of a total of 184 patients with the diagnosis of tubal EP, who received MTX as their first-line treatment. Patients with a baseline β-HCG< 4800 mIU/mL received single-dose MTX (n = 136) and those with an initial β-HCG≥ 4800 mIU/mL underwent the double-dose MTX regimen (n = 48).

Introduction: Colorectal cancer (CRC) surgery complications are a major issue affecting morbidity and mortality rates. Anastomotic stricture, which occurs in almost 30% of patients after surgery for rectal cancer, is one of the most serious but underreported side effects. In this study, we tried to assess the effect of stapler size on anastomotic stricture rate.
