Determination of Whole Blood Loss From Minimally Invasive Myomectomy Using a Standardized Formula: A Pilot Study.

STUDY OBJECTIVE: To determine the median perioperative blood loss (PBL) during minimally invasive surgical (MIS) myomectomy. DESIGN: Prospective pilot study. SETTING: Large academic teaching hospital. PATIENTS: Thirty-one patients underwent laparoscopic or robotic myomectomy and completed a postoperative complete blood count (CBC) from November 2020 to August 2022. Patients had to have at least one fibroid greater than or equal to 3 cm on preoperative imaging. INTERVENTIONS: A CBC was collected preoperatively within 7 days of surgery. Estimated blood loss (EBL) was determined by the surgeon intraoperatively. A repeat CBC was drawn between postoperative days 2 through 4. PBL was calculated using the equation PBL = (patient weight in kg × 65 cc/kg) × (preoperative hematocrit - postoperative hematocrit)/preoperative hematocrit. MEASUREMENTS AND MAIN RESULTS: Median PBL (536.3 cc [270.0, 909.3]) was greater than median EBL (200.0 cc [75.0, 500.0]). PBL ranged from a net gain of 191.5 cc to net loss of 2362.5 cc. Median size of the largest fibroid on preoperative imaging was 8.8 cm (6.6, 11.5), and median weight of fibroids removed was 321 g (115, 519). About half of patients (51.6%) had one fibroid removed, and 48.4% had 2 or more fibroids removed. Five patients were converted to laparotomy, 4 from robotic approaches. Two patients required a blood transfusion. CONCLUSION: Calculated PBL was greater than intraoperative EBL. This suggests there is continued blood loss post myometrial bed closure. Blood loss should be evaluated both during and after myomectomy, as intraoperative EBL underestimates total PBL.

Birth Plans and Childbirth Education: What Are Provider Attitudes, Beliefs, and Practices?

We describe the perception and practices of obstetric providers on birth plans and childbirth education (CBE) classes. Using a national online survey, we collected provider and patient demographics, practice settings, and perceptions. Of 567 surveys, 77% were physicians and 22% were midwives. This cohort believed prenatal care and CBE were predictors of patient satisfaction, while they had unfavorable views of birth plans. Most providers routinely recommended (69.7%) and had favorable views on CBE (84%). Most providers (66.5%) did not recommend birth plans and 31% felt they were predictors of poor obstetrical outcomes. Further research is needed to bridge the gap between provider beliefs and patient desires about their birth experience as well as to understand how to improve childbirth-related patient satisfaction.

The Influence of Exercise Environment and Gender on Mood and Exertion.

This study examined the influence of exercise environment and gender on post-exercise mood and exertion. College student participants (55 females, 49 males) were instructed to pedal a stationary bike at a moderate pace for 20 minutes. Participants were randomly assigned to one of three laboratory conditions: (1) exercising in front of a mirror and posters showing ideal fit body types (i.e., celebrity male and female personal trainers), (2) exercising in front of a mirror only, or (3) a control condition in which participants exercised without a mirror or posters. The Activation-Deactivation Adjective Check List (AD-ACL), measuring exercise-induced mood states, was administered both before and after exercise. Average bike speed throughout the exercise session measured exertion. Mirrors and posters of ideally fit celebrities did interact with gender on post-exercise tension in that women felt most tense after exercising in front of the mirror and posters while men were most tense after exercising in front of the mirror only. Exercise exertion was also impacted by experimental condition such that participants rode significantly faster in the mirror and posters condition. There was no significant interaction of gender and condition on exercise exertion, but women pedaled fastest in the mirror and poster condition relative to the other conditions. Results suggest that exercise exertion and tension reduction are partially a by-product of gender and exercise environment.

Comparison of behavioral treatment conditions in buprenorphine maintenance.

BACKGROUND AND AIMS: The Controlled Substances Act requires physicians in the United States to provide or refer to behavioral treatment when treating opioid-dependent individuals with buprenorphine; however, no research has examined the combination of buprenorphine with different types of behavioral treatments. This randomized controlled trial compared the effectiveness of four behavioral treatment conditions provided with buprenorphine and medical management (MM) for the treatment of opioid dependence. DESIGN: After a 2-week buprenorphine induction/stabilization phase, participants were randomized to one of four behavioral treatment conditions provided for 16 weeks: cognitive behavioral therapy (CBT = 53); contingency management (CM = 49); both CBT and CM (CBT + CM = 49); and no additional behavioral treatment (NT = 51). SETTING: Study activities occurred at an out-patient clinical research center in Los Angeles, California, USA. PARTICIPANTS: Included were 202 male and female opioid-dependent participants. MEASUREMENTS: Primary outcome was opioid use, measured as a proportion of opioid-negative urine results over the number of tests possible. Secondary outcomes include retention, withdrawal symptoms, craving, other drug use and adverse events. FINDINGS: No group differences in opioid use were found for the behavioral treatment phase (χ2 = 1.25, P = 0.75), for a second medication-only treatment phase, or at weeks 40 and 52 follow-ups. Analyses revealed no differences across groups for any secondary outcome. CONCLUSION: There remains no clear evidence that cognitive behavioural therapy and contingency management reduce opiate use when added to buprenorphine and medical management in opiate users seeking treatment.

Comparing buprenorphine induction experience with heroin and prescription opioid users.

Prescription opioid (PO)-dependent treatment presentations are becoming increasingly common; however, most research on the treatment of opioid-dependent populations has been conducted in heroin users. The aim of this secondary data analysis was to compare the buprenorphine induction experience of 167 heroin and 61 PO users. Results demonstrate that although the groups differed on some baseline characteristics, many of the key induction experience variables were comparable between the groups. Heroin users were found to have significantly higher preinduction Clinical Opiate Withdrawal Scale (COWS) scores (p = .014) and postinduction COWS score (p = .008) compared with the PO users. No differences between groups were found for self-reported craving and withdrawal scores, mean buprenorphine dose on Day 1, or retention at the end of the first week. The findings of this study suggest that existing buprenorphine induction practices developed for heroin users appear to be equally effective with PO users.
