AI Article Synopsis
- The study compares the effects of propofol and thiopental as induction agents during cesarean sections on bispectral index (BIS) levels, which measure anesthesia depth.
- Patients were divided into two groups: one received thiopental and the other propofol, with results showing that the propofol group had significantly lower BIS values during key surgical moments.
- The findings suggest that propofol offers better control over vital signs and anesthesia depth compared to thiopental during cesarean delivery.
Article Abstract
Background: Since in caesarean operations skin incision to delivery time is very short, induction agent could be still effective on BIS level till the time of delivery. Therefore this study was designed to analyze the effect on maintaining adequate bispectral index levels till delivery of neonate of propofol and thiopental as an induction agent for caesarean section.
Methods: Eighty two patients undergoing caesarean section were allocated into two groups. In the group T anesthesia induction was performed with thiopental (5 mg/kg) and in the group P with propofol (2.5 mg/kg). Anesthesia was maintained with sevoflurane. Heart rates, blood pressures and BIS values during significant events of surgery and anesthesia till delivery, durations of surgery, induction to skin incision and to delivery and Apgar scores were recorded. For statistical analysis T-test was used for comparison of means of independent samples.
Results: The groups were comparable with respect to age, weight and gestational age. The patients in the group P had significantly lower levels of bispectral index values during uterus incision; 40.6 vs. 59.5 (p = 0.019) and delivery; 41 vs. 62.9 (p = 0.018).
Conclusion: Anesthesia induction with propofol in a dose of 2.5 mg/kg maintains lower levels of heart rate, blood pressure and BIS till delivery when compared with thiopental in a dose of 5 mg/kg. There is no financial support taken from any kind of company or person. There are no financial relationships between authors and commercial interests with a vested interest in the outcome of study.

State Key Laboratory of Quality Research in Chinese Medicine, Institute of Chinese Medical Sciences, University of Macau, Macao SAR, China.
Background: The role of hospital pharmacists in managing cell and gene therapy (CGT) and advanced therapy medicinal products (ATMPs) is gradually being recognized but the evidence about impact of their role has not been systematically reported.
Objective: This study was aimed to summarize the professional services provided by hospital pharmacists on managing CGT/ATMPs and the evidence about the effects on patient care, as well as to identify the perceptions about pharmacists assuming a role that supports the appropriate and safe use of CGT/ATMPs.
Methods: Literature from 4 electronic databases (PubMed, ScienceDirect, Web of Science, Scopus) were searched following PRISMA checklist to yield publications on the interventions provided by hospital pharmacists in the management of CGT/ATMPs dated since 1 January 2013 till 30 April 2023.

Background: Preclinical studies have documented the role of alpha-adrenergic agonists in myometrial contraction. Phenylephrine is frequently used to prevent and treat post-spinal hypotension during cesarean delivery. We hypothesized phenylephrine would reduce postpartum blood loss due to alpha-1 receptor-mediated uterine and vascular smooth muscle contraction.

Objective: This study aimed to assess the effectiveness of a dual digital alert system and automatic radiologist reassignment in improving the efficiency of quantitative imaging report delivery for clinical trials.
Materials And Methods: Assessing tumor metrics is critical to oncologic disease management, informed treatment planning, and for monitoring therapeutic response and even more so in cancer clinical research trials. A collaborative effort with the Institutional Research Information Systems division led to developing a web-based system with a Java backend, tested using Agile methodology to improve patient care with improved turnaround time (TAT) of quantitative reports.

Objective: Antenatal magnesium sulfate has been reported to reduce the risk of neurological impairment in fetuses born to women at risk of preterm labor. However, the evidence to support its use is conflicting. We conducted this meta-analysis to assess the efficacy and safety of magnesium sulfate in women at risk of preterm labor as new research is available from RCTs giving insights into MgSO4 treatment among differing gestational age groups.

GDM is an increasing global concern, with its etiology not fully understood, though altered placental function is likely to play a role. Placental angiogenesis, essential for sufficient blood flow and nutrient exchange between mother and fetus, may be affected by GDM. However, the role of angiogenic markers in GDM remains unclear.
