RESUMO
BACKGROUND: The decision regarding intraoperative transfusion has traditionally been based on hemodynamic instability and estimated blood loss. We performed a systematic review to determine the validity of the oximetry method compared to standard of care for hemoglobin measurement. METHODS: A systematic literature review was conducted, and several libraries were searched from inception to March 31,2023. The primary outcome was comparing the mean difference between laboratory-derived hemoglobin and non-invasive, point-of-care hemoglobin measurement. Subgroup analysis included comparing the mean difference in the pediatric population and among female patients. RESULTS: A total of 276 studies were identified, and 37 were included. We found that the pooled mean difference varied qualitatively between adult and pediatric population (p value for heterogeneity <0.001). In adult populations, lab hemoglobin measurements were on average slightly higher than non-invasive measurements (mean difference = 0.23; 95% CI -0.13, 0.59), though there was greater heterogeneity across studies (I2 = 97%, p value = <0.001). In the pediatric population, most studies showed lab hemoglobin to be slightly lower (mean difference = -0.42; 95% CI -0.87 to 0.03). CONCLUSIONS: In general, there was no clinically significant difference in mean hemoglobin among adult and pediatric populations. The percentage of female participants had no effect on the mean difference in hemoglobin.
RESUMO
Our findings suggest that treating antepartum anemia with currently available iron therapies would result in significant cost-savings and reductions in adverse outcomes associated with anemia in this context. Ferric carboxymaltose likely confers the greatest overall benefit among competing options. This conclusion is robust to uncertainty, even when the cost these therapies is significantly higher than is demonstrated in the literature.
RESUMO
Postpartum hemorrhage is a significant contributor to maternal mortality worldwide and in the United States. Tranexamic acid (TXA) has been shown to reduce PPH complications although it is not routinely recommended for use as prophylaxis to date. To estimate the cost-effectiveness of alternative risk-dictated strategies utilizing prophylactic tranexamic acid for the prevention of postpartum hemorrhage. We constructed a microsimulation-based Markov decision-analytic model estimating the cost-effectiveness of three alternative risk-dictated strategies for tranexamic acid prophylaxis versus the no prophylaxis in a cohort of 3.8 million pregnant women delivering in the United States. Each strategy differentially modified risk-specific hemorrhage probabilities by preliminary estimates of tranexamic acid's prophylactic efficacy. Outcome measures included incremental costs, quality-adjusted life-years, and outcomes averted. Costs and benefits were considered from the healthcare system and societal perspectives over a lifetime time horizon. All intervention strategies were dominant versus no prophylaxis, implying that they were simultaneously more effective and cost-saving. Prophylaxing delivering women irrespective of hemorrhage risk produced the most favorable results overall, with estimated cost savings greater than $690 million and up to 149,505 PPH cases, 2,933 hysterectomies, and 70 maternal deaths averted, per annual cohort. Threshold analysis suggested that tranexamic acid is likely to be cost-saving for health systems at costs below $190 per gram. Our findings suggest that routine prophylaxis with tranexamic acid would likely result in substantial cost-savings and reductions in adverse maternal outcomes in this context. This study is a cost-effectiveness analysis demonstrating cost-savings and reduction in adverse maternal outcomes with routine tranexamic acid as prophylaxis for post-partum hemorrhage.

OBJECTIVE: We describe provider documented counseling patterns and perception regarding HPV vaccination among patients with a history of cervical dysplasia. METHODS: All patients ages 21-45 who underwent colposcopy at a single academic medical center from 2018 to 2020were sent a self-administered survey through the electronic medical record patient portal to assess their attitudes regarding human papillomavirus (HPV) vaccination. Demographic information, HPV vaccination history, and documented obstetrics and gynecology provider counseling at the time of colposcopy were examined. RESULTS: Of 1465patients, 434 (29.6 %) reported or had documented receipt of at least one dose of the human papillomavirus vaccine. The remainder reported they were not vaccinated or had no documentation of vaccination. Proportion of vaccinated patients was higher among White compared to Black and Asian patients (P = 0.02). On multivariate analysis, private insurance (aOR 2.2, 95 % CI 1.4-3.7) was associated with vaccinated status while Asian race (aOR 0.4, 95 % CI 0.2-0.7) and hypertension (aOR 0.2, 95 % CI 0.08-0.7) were less likely to be associated with vaccination status. Among patients with unvaccinated or unknown vaccination status, 112 (10.8 %) received documented counseling regardingcatch-up human papillomavirus vaccination at a gynecologic visit. Patients seen by a sub-specialist obstetrics and gynecologic provider were more likely to have documented provider counseling regarding vaccination compared to those seen by a generalist obstetric/gynecologist provider (26 % vs 9.8 %, p < 0.001). Patients cited lack of physician discussion (53.7 %) and the belief that they were too old to receive the HPV vaccine (48.8 %) as the main reasons for remaining unvaccinated. CONCLUSION: HPV vaccination and the rate of obstetric and gynecologic provider counseling regarding HPV vaccination among patients undergoing colposcopy remains low. When surveyed, many patients with a history of colposcopy cited provider recommendation as afactor in their decision to undergo adjuvant HPV vaccination, demonstrating the importance of provider counseling in thisgroup.

BACKGROUND: Infections caused by Pseudomonas aeruginosa are difficult to treat with a significant cost and burden. In Lebanon, P. aeruginosa is one of the most common organisms in ventilator-associated pneumonia (VAP). P. aeruginosa has developed widespread resistance to multiple antimicrobial agents such as fluoroquinolones and carbapenems. We aimed at identifying risk factors associated for P. aeruginosa infections as well as identifying independent risk factors for developing septic shock and in-hospital mortality. METHODS: We used a cross-sectional study design where we included patients with documented P. aeruginosa cultures who developed an infection after obtaining written consent. Two multivariable regression models were used to determine independent predictors of septic shock and mortality. RESULTS: During the observed period of 30 months 196 patients were recruited. The most common predisposing factor was antibiotic use for more than 48 hours within 30 days (55%). The prevalence of multi-drug resistant (MDR) P. aeruginosa was 10%. The strongest predictors of mortality were steroid use (aOR = 3.4), respiratory failure (aOR = 7.3), identified respiratory cultures (aOR = 6.0), malignancy (aOR = 9.8), septic shock (aOR = 18.6), and hemodialysis (aOR = 30.9). CONCLUSION: Understanding resistance patterns and risk factors associated with mortality is crucial to personalize treatment based on risk level and to decrease the emerging threat of antimicrobial resistance.

Both thrombocytopenia (platelet count < 150 × 103/µL) and anemia have been associated with postpartum hemorrhage (PPH). However, the impact of thrombocytopenia on PPH risk among women with mild and severe anemia is unknown. We sought to evaluate the association between thrombocytopenia and anemia in increasing risk of PPH. We performed a secondary analysis of a retrospective cohort of pregnant women from 19 hospitals across the United States from 2016 to 2021. Women who had a term singleton pregnancy and hematocrit (Hct) ≤ 33% at delivery were included in the study. The primary outcome was PPH (defined as blood loss ≥ 1000 mL or blood transfusion). We also analyzed the effect of severe anemia (Hct < 28%) on the association between PPH and thrombocytopenia. Chi-squared tests and Fisher's exact tests were used for categorical variables and an independent t-test was used for continuous variables. There were 20,808 women who met our inclusion criteria, of which 1793 (8.6%) had platelet count < 150 × 103/µL. The prevalence of PPH was 6.4%. Compared with women with normal platelet count, those with thrombocytopenia had 1.3-fold higher odds of PPH [6.8% vs. 4.5%, adjusted OR 1.3 (1.1-1.7)]. Platelet count ≥ 150 × 103/µL was associated with decreased odds of PPH among patients with hct between 28 and 33% and hct < 28%. In conclusion, anemic women with term singleton pregnancies who delivered with thrombocytopenia had a higher frequency of PPH. Normal platelet count at delivery was protective against PPH in the setting of anemia regardless of severity.

There is paucity of evidence to support clinical decision making and counselling related to medication use in pregnancy. Despite multiple efforts from legislative bodies and advocacy groups, the inclusion of pregnant women in clinical drug trials assessing efficacy and safety remains scarce. Pregnancy can be complicated by multiple comorbidities that require pharmacological intervention; these interventions primarily target the pregnant woman but also sometimes have secondary effects for the foetus. The US Food and Drug Administration has issued multiple guidance documents on incorporating pregnant women in clinical trials to aid pharmaceutical companies in designing a protocol to ensure safety and adherence to ethical standards. Advances in paediatric pharmacology studies provide lessons for researchers on the best practice of designing clinical trials with inclusion of patients from special populations. In this review, we present the status of pregnant women in clinical trials, highlighting the ethical stigma and possible future directives.

OBJECTIVE: Endocervical curettage (ECC) during colposcopy is recommended in certain circumstances; however, diagnostic use remains unclear. We evaluate the utility of ECC among patients with non-fully visualized squamocolumnar junction (SCJ) and certain patient socioeconomic factors. METHODS: Retrospective chart analysis was completed for patients aged older than 21 years who underwent a colposcopy at 2 study sites between 2012 and 2021. Demographics and histopathologic results were analyzed. RESULTS: A total of 1,516 colposcopies were reviewed; 73.8% (n = 1,119) had an ECC with colposcopy. Of those, 92.1% (n = 1,031) had benign ECC whereas 13.9% (n = 156) had a positive ECC at time of colposcopy. Most patients with benign ECC had benign/low-grade squamous intraepithelial lesion pathology on colposcopy biopsy (82.3%; n = 914; p < .001), and most patients with high-grade squamous intraepithelial lesion (HSIL) on ECC had HSIL on colposcopy biopsy (63.4%; n = 52; p < .001) However, when looking at patients with high-grade pathology on colposcopy biopsy, it was seen that most had benign or low-grade squamous intraepithelial lesion on ECC (79.5%; n = 205; p < .001). Most patients with adequately visualized SCJ on colposcopy were noted to have HSIL on biopsy and negative ECC (73%; n = 81; p < .001). This result was similar in patients with non-fully visualized SCJ, although not statistically significant. When stratified by socioeconomic status, most patients with high-grade lesions had a benign ECC. CONCLUSIONS: Endocervical curettage has been described to increase the identification of high-grade lesions at time of colposcopy. This descriptive study shows that many high-grade lesions at time of excisional procedure had a benign ECC on colposcopy, with no demonstrated clear additional utility in high-risk groups.

Medication use in pregnancy is common. However, there is a gap in the literature assessing the knowledge of pregnant individuals about medication use in pregnancy. The aim of our study is to assess the knowledge, attitudes, and beliefs of pregnant people on medication use in pregnancy. We conducted a cross-sectional survey questionnaire that was completed by pregnant patients from December 2021 to January 2022. The survey included questions regarding knowledge, attitude, and sources for obtaining information about medication use in pregnancy and general statements from the Beliefs about Medicines Questionnaire (BMQ). A total of 150 participants completed the survey. Most patients reported that a person should know that medication use for chronic diseases must be modified during pregnancy and that medications can be used in any trimester of pregnancy. Most reported that medication use can lead to fetal growth restriction and maternal bleeding. The mean scores (SDs) on the BMQ-General for the overuse, harm, and benefit statements were 8.7 (2.4), 8.2 (3.1), and 15.7 (2.8). Even though medication use in pregnancy is common, it is an area of concern to pregnant patients. More research on identifying the risks of different medicines used in pregnancy is thus needed.

OBJECTIVE: To evaluate if the implementation of a colorimetric quantitative blood loss (QBL) system during cesarean delivery improves clinical outcomes. METHODS: We conducted a retrospective cohort analysis after cesarean section before and after implementation of the Triton based colorimetric QBL system. Prevalence of postpartum hemorrhage, amount of blood products transfused, length of hospitalization, and rates of intensive care unit (ICU) admission were compared. RESULTS: A total of 2221 patients were included. There were 1192 patients in the pre-intervention group and 1029 patients in the post-intervention group. There was no significant difference between groups in the prevalence of postpartum hemorrhage (8.6% vs 9.3%, P = 0.57), amount of packed red blood cells (pRBCs) transfused (45 vs 30, P = 0.41) or average length of hospital stay in days (3.0 vs 3.0, P = 0.37). There was a statistically significant decrease in ICU admissions between the pre- and post-intervention groups (2.2% vs 1.0%, P = 0.02). CONCLUSION: There was no effect of implementation of the colorimetric QBL application system on diagnosis of postpartum hemorrhage, amount of blood products transfused, or length of hospital stay. Although a significant decrease in ICU admissions was observed, we could not determine if these transfers were hemorrhage related.

OBJECTIVE: Clarify the normal patterns of voiding after minimally invasive hysterectomy. We also aim to identify perioperative factors associated with delayed time to void immediately following hysterectomy. DESIGN: Retrospective cohort study SELECTION: Women undergoing laparoscopic hysterectomy between September 2012 to October 2018 at a single academic university hospital. RESULTS: 450 minimally invasive hysterectomies were included in the final analysis, 274 (60.9%) robotically-assisted, and 176 (39.1%) conventional laparoscopy. The overall median postoperative time-to-void following a retrograde bladder filling of 150 mL normal saline was 179 min. Based on the 50th percentile of the distribution of the time-to-void, two groups were created. Demographic characteristics between the groups were similar, except those who were above the 50th percentile were more likely to be older, have a reported history of previous myomectomy, and had a longer postoperative PACU stay compared to those below or equal to the 50th percentile. The mean time-to-void following conventional laparoscopic hysterectomy was less than that of robotic surgery (187.3 vs 200.5 min) however the difference was not statistically significant (p=.22). The use of hydromorphone intraoperatively and the combination of oxycodone-acetaminophen postoperatively were more likely to be associated with the group of patients above the 50th percentile but there was no significant difference in perioperative utilization of median morphine milliequivalents (MME) between the two groups. CONCLUSIONS: Following laparoscopic hysterectomy (either conventional or with robotic-assistance) with a retrograde bladder fill of 150 mL normal saline most patients will void within 4 h after surgery. This is consistent with historic data on normal voiding patterns facilitating safe same day discharge without prolonged time in the PACU.

Endometriosis is a complex chronic inflammatory condition that can create a multitude of bothersome painful symptoms for women. Bowel endometriosis is often misdiagnosed or overlooked leading to years of suffering for many women. The surgical management of bowel endometriosis varies based on extent of disease as well as surgeon experience. Surgical treatment for bowel endometriosis is complex and a variety of intraoperative and postoperative complications must be considered. Two significant postoperative complications for bowel endometriosis include anastomotic leak and fistula formation. There is continued debate regarding the appropriate surgical treatment for bowel endometriosis. Aggressive surgery with segmental bowel resection is being utilized more cautiously, with an increase in less aggressive shaving or disc excision techniques. Historic beliefs regarding the limitations of shaving and disc excision are being challenged, and with a reduction in morbidity these less aggressive techniques are winning favor among gynecologic surgeons. Shaving, discoid excision, and segmental bowel resection are all feasible surgical management options for bowel endometriosis. Segmental resection is associated with the highest rates of both anastomotic leak and fistula formation, while shaving is associated with the lowest.
RESUMO
One strategy thought to reduce direct costs associated with robotic surgery is minimizing the number of robotic arms used for a surgery. We aim to demonstrate the safety and feasibility of the three-port robot-assisted hysterectomy across uterine weights. Retrospective cohort study in a tertiary care university hospital of consecutive patients undergoing a three-port robot-assisted hysterectomy for benign indications. All surgeries were performed between 2012 and 2018 by fellowship-trained minimally invasive gynecologic surgeons. Data from 232 patients were collected. Eighty-eight (37.9%) patients had a uterine weight < 250 g, 63 (27.2%) had a uterine weight between 250 and 500 g, 51 (22.0%) had a uterine weight between 500 and 1000 g, and 30 (12.9%) had a uterine weight ≥ 1000 g. Multivariable regression analysis revealed no statistically significant differences between uterine weight groups and time spent in PACU, the total length of hospital stay, or direct cost. When setting the < 250 g as referent, patients with uterine weights between 500 and 1000 g, and more than 1000 g had an operative time that was on average 23.4% and 91.6% longer than patients with uterine weight < 250 g, respectively (p < 0.01). Patients with uterine weights between 500 and 1000 g and more than 1000 g had an EBL that was on average 35% and 156% higher than patients with uterine weight < 250 g, respectively (p < 0.01). Our data support the safety and feasibility of the three-port robot-assisted hysterectomy technique across uterine weights.

BACKGROUND: Infections due to antibiotic resistant organisms (ARO) among hospitalized patients are associated with increased morbidity, mortality, and healthcare costs. Longitudinal data about antimicrobial resistance are scarce in Lebanon and the region. The objective of this study is to describe the temporal trends of resistance of selected pathogens among hospitalized patients at a tertiary care center in Lebanon. METHODS: We conducted a retrospective review of surveillance data from 2010 until 2018. Six target organisms isolated from hospitalized patients were included: carbapenem-resistant Escherichia coli (CREC), carbapenem-resistant Klebsiella spp. (CRKP), multi-drug resistant Pseudomonas aeruginosa (MDRPA), carbapenem-resistant Acinetobacter baumannii (CRAB), methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant Enterococcus spp. (VRE). Correlation analysis was performed to evaluate for temporal trends. RESULTS: A total of 15,901 isolates were examined, most of which were obtained from urinary specimens. Among Gram-negative organisms, the highest resistance was found among CRAB (81.7%), followed by CRKP (6.5%) and CREC (3.3%). MDRPA overall prevalence was 0.8%. Among Gram-positive organisms, the prevalence of MRSA and VRE was 26.2% and 2.6%, respectively. CREC, MRSA, and VRE showed statistically significant increasing temporal trends, while CRAB decreased significantly from 2013 to 2018. CONCLUSION: These data are helpful in characterizing the epidemiology of antimicrobial resistance in Lebanon and show that controlling emerging resistance is achievable with concerted infection control and antimicrobial stewardship efforts. Caution should be exercised to contain early on the spread of CREC and of resistant Gram-positive pathogens.

Health-care costs are affected by obesity with both the direct and indirect costs of health care increasing as body mass index (BMI) increases. However, one important aspect of obesity that lacks rigorous study is what impact BMI has on direct surgical cost. We performed a retrospective cohort study of women undergoing a laparoscopic hysterectomy at our single academic university center between January 2012 and December 2017. Women were excluded if their surgery was performed by anyone other than those surgeons with subspecialty training in minimally invasive gynecologic surgery (MIGS), if their hysterectomy was performed by a modality other than conventional laparoscopy or with robotic assistance, or if the indication for hysterectomy was related to any gynecologic malignancy. We identified 600 patients who underwent laparoscopic hysterectomy during the study period. Women who underwent robotic hysterectomy, compared to laparoscopic, had a shorter operative time, lower estimated blood loss, and shorter length of stay. Mean direct cost (± standard deviation) for the cohort was $6398.53 ± $2304.67, age was 44.5 ± 7.5 years, and BMI was 32.2 ± 7.6. Direct cost for all laparoscopic hysterectomies was evaluated across the five different BMI quintiles and no significant difference between groups was found. There was no significant difference in direct cost across procedures between obese and non-obese patients (p = 0.62) and this remained true when separated out by surgical modality. However, when evaluating morbidly obese patients, there appears to be a trend toward cost reduction with robotic hysterectomy compared to conventional laparoscopy. It does not appear that BMI has a statistically significant impact on direct cost between robotic-assisted and conventional laparoscopic hysterectomy. However, these findings may be due to surgical proficiency and warrant further investigation among surgeons with lesser volume.

BACKGROUND: The infectious complications in hemodialysis patients are still among the main reasons for their increased morbidity and mortality. The possible reasons behind this might be due to impairments in the host defense mechanisms, comorbidities, invasive procedures and pathogenicity of the infecting organisms. With the increased incidence of bacteremia in hemodialysis patients and the overt use of antibiotics, we have witnessed a rise in the number of new multidrug resistant (MDR) strains in those patients. AIM: We aim to determine the epidemiology, risk factors and complications of infections in patients receiving chronic hemodialysis, particularly bloodstream infections. METHODS: This is a retrospective case-control study involving patients undergoing hemodialysis at a tertiary care center. We studied the prevalence of infectious complications among those patients as well as the responsible agent in each respective infectious episode and the risk factors associated with bacteremia. FINDINGS: 46.6% of the studied population had at least one documented episode of infection. The most common were blood and respiratory infections (33.2% and 32.7% respectively). Among patients with bacteremia, coagulase-negative Staphylococcus was the predominant pathogen (49% of cases), followed by Staphylococcus aureus and Escherichia coli. Mortality was higher in patients who had MDR bacteremia, and in those who had mechanical ventilation or intensive care unit (ICU) admission. CONCLUSION: Due to the alarming increase in the incidence of infection among hemodialysis patients and its strong association with mortality, further studies are needed to look for risk factors associated with infection and for ways to control those risk factors.

The extensive metabolic demands of pregnancy require specific physiological and anatomical changes. These changes affect almost all organ systems, including the cardiovascular, respiratory, renal, gastrointestinal, and hematologic system. The placenta adds another layer of complexity. These changes make it challenging for clinicians to understand presenting signs and symptoms, or to interpret laboratory and radiological tests. Furthermore, these physiological alterations can affect the pharmacokinetics and pharmacodynamics of drugs. Drug safety in lactation is only supported by limited evidence. In addition, the teratogenic effects of medications are often extrapolated from animals, which further adds uncertainties. Unfortunately, pregnant women are only rarely included in clinical drug trials, while doses, regimens, and side effects are often extrapolated from studies conducted in non-pregnant populations. In this comprehensive review, we present the changes occurring in each system with its effects on the pharmacokinetic variables. Understanding these physiological changes throughout normal pregnancy helps clinicians to optimize the health of pregnant women and their fetuses. Furthermore, the information on pregnancy-related physiology is also critical to guide study design in this vulnerable 'orphan' population, and provides a framework to explore pregnancy-related pathophysiology such as pre-eclampsia.

Postpartum hemorrhage is a leading cause of maternal death globally. Recent studies have associated Type-O group to increased risk of bleeding. We aimed to determine if women with Type-O blood are at higher risk of PPH. This is a retrospective cohort analysis of a multi-center database included women admitted to labor and delivery from January 2015 to June 2018. All deliveries resulting in live birth were included. Association between Type-O and non Type-O were examined using chi-square test and fishers exact test. Prevalence of postpartum hemorrhage, estimated blood loss, drop in hematocrit and red blood cell transfusion were compared. The matched sample included 40,964 Type-O and the same number of no Type-O. The overall prevalence of postpartum hemorrhage was 6.4%, and there was no difference in the prevalence of PPH among Type-O compared to non Type-O (6.38% vs. 6.37% respectively; p = 0.96). There was no difference in hematocrit drop and estimated blood loss between Type-O and non Type-O in all deliveries. However, in cesarean delivery there was a significant difference in blood loss among the two groups. Finally, Type-O had 1.09-fold increased risk for transfusion compared to non Type O (95% CI 0.9-1.34). There is an association between Type-O group and risk of bleeding in women undergoing cesarean delivery. More prospective studies, taking into account coagulation profile, platelet count and tissue factors, are needed to draw a conclusion on whether ABO system can be considered a heritable risk of postpartum hemorrhage.

The involvement of the cervix as a site of relapse for hematologic malignancies is rare. We herein present a case of relapsed B-cell Acute Lymphoblastic Leukemia/Lymphoma (ALL) mimicking advanced cervical cancer. The patient is a 61-year-old female with history B-cell ALL and had multiple relapses confined to the bone marrow and had received several different chemotherapy regimens. She presented with lower abdominal pain after the end of her last cycle for which an MRI abdomen and pelvis was done and it showed the presence of an asymmetrical cervical mass. Further imaging included a PET-CT showing the presence of hypermetabolic cervical mass with left pelvic and retroperitoneal lymph node involvement. She underwent a biopsy of 3 distinct lesions in the cervix and vagina and a diagnosis of relapsed B-cell ALL was confirmed in two out of the three specimens.
