- Abstract
Objective: To identify and support correction of misspelled medication names recorded as free text, we compared the relative effectiveness of two user-friendly methods, used without reliance on clinical knowledge., Methods: Leveraging the SAS® COMPGED function, fuzzy string search programs examined 1.8 million medication records from 183,600 World Trade Center General Responder Cohort monitoring visits conducted in New York and New Jersey between 7/16/2002 and 3/31/2021, producing replicable generalized edit distance scores between the reported and correct spelling. Scores < 120 were selected as optimal and compared to Stedman's 2020 Plus Medical/Pharmaceutical Spell Checker first suggested word, used as the comparative standard because it employs both spelling and phonetic similarities to suggest matching words. We coded each methods' results as identifying or not identifying the medications within each visit., Results: Most types of medications (94.4 % anxiety, 98.4 % asthma and 94.6 % ulcer/gastroesophageal reflux disease) were correctly spelled. Cross tabulations assessed the agreement (anxiety 99.9 %, asthma 99.6 % and 98.4 % ulcer/ gastroesophageal reflux disease), false positive (respectively 0.02 %, 0.03 % and 2.0 %) and false negative (respectively 1.9 %, 0.5 % and 1.0 %) values. Scores < 120 occasionally correctly identified medications missed by the spell checker. We observed no difference in medication misspellings across socio-economically and culturally diverse patient characteristics., Conclusions: Both methods efficiently identified most misspelled medications, greatly minimizing the review and rectification needed. The fuzzy method is more universally applicable for condition-specific medications identification, but requires more programming skills. The spell checker is inexpensive, but benefits from modest programming skills and is only available in some languages., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

- Abstract
Background: The World Trade Center (WTC) general responder cohort (GRC) was exposed to environmental toxins possibly associated with increased risk of developing autoimmune conditions., Objectives: Two study designs were used to assess incidence and risks of autoimmune conditions in the GRC., Methods: Three clinically trained professionals established the status of possible GRC cases of autoimmune disorders adhering to diagnostic criteria, supplemented, as needed, by specialists' review of consenting responders' medical records. Nested case-control analyses using conditional logistic regression estimated the risk associated with high WTC exposure (being in the 9/11/2001 dust cloud or ≥median days' response worked) compared with low WTC exposure (all other GRC members'). Four controls were matched to each case on age at case diagnosis (±2 years), sex, race/ethnicity, and year of program enrollment. Sex-specific and sensitivity analyses were performed. GRC age- and sex-adjusted standardized incidence ratios (SIRs) were compared with the Rochester Epidemiology Project (REP). Complete REP inpatient and outpatient medical records were reviewed by specialists. Conditions meeting standardized criteria on ≥2 visits were classified as REP confirmed cases., Results: Six hundred and twenty-eight responders were diagnosed with autoimmune conditions between 2002 and 2017. In the nested case-control analyses, high WTC exposure was not associated with autoimmune domains and conditions (rheumatologic domain odds ratio [OR] = 1.03, 95% confidence interval [CI] = 0.77, 1.37; rheumatoid arthritis OR = 1.12, 95% CI = 0.70, 1.77). GRC members had lower SIR than REP. Women's risks were generally greater than men's., Conclusions: The study found no statistically significant increased risk of autoimmune conditions with WTC exposures., (© 2021 Wiley Periodicals LLC.)

- Abstract
We describe the chemical synthesis of the fungal naphthopyrones YWA1 and fonsecin B, as well as their functionalization with an amine-spacer arm and the conjugation of the resulting molecules to three different functional tags (i.e., biotin, Oregon green, 1-[3-(succinimidyloxycarbonyl)benzyl]-4-[5-(4-methoxyphenyl)-2-oxazolyl]pyridinium bromide (PyMPO)). The naphthopyrone-biotin and -PyMPO constructs maintained the ability to bind the C-type lectin receptor MelLec, whose interaction with immunologically active fungal metabolites (i.e., 1,8-dihydroxynaphthalene-(DHN)-melanin and YWA1) is a key step in host recognition and induction of protective immune responses against Aspergillus fumigatus . The fluorescent Fonsecin B-PyMPO construct 21 was used to selectively visualize MelLec-expressing cells, thus validating the potential of this strategy for studying the role and functions of MelLec in immunity.

- Abstract
Objective: The aim of this study was to evaluate the effect of a midwife-performed checklist and limited obstetric ultrasound on sensitivity and positive predictive value for a composite outcome comprising multiple gestation, placenta praevia, oligohydramnios, preterm birth, malpresentation, abnormal foetal heart rate., Design: Quasi-experimental pre-post intervention study., Setting: Maternity unit at a district hospital in Eastern Uganda., Interventions: Interventions were implemented in a phased approach: standardised labour triage documentation (Phase 1), a triage checklist (Phase 2), and checklist plus limited obstetric ultrasound (Phase 3)., Participants: Consenting women presenting to labour triage for admission after 28 weeks of gestation between February 2018 and June 2019 were eligible. Women not in labour or those requiring immediate care were excluded. 3,865 women and 3,937 newborns with similar sample sizes per phase were included in the analysis., Measurement and Findings: Outcome data after birth were used to determine true presence of a complication, while intake and checklist data were used to inform diagnosis before birth. Compared to Phase 1, Phase 2 and 3 interventions improved sensitivity (Phase 1: 47%, Phase 2: 68.8%, Phase 3: 73.5%; p ≤ 0.001) and reduced positive predictive value (65.9%, 55%, 48.7%, p ≤ 0.001) for the composite outcome. No phase differences in adverse maternal or foetal outcomes were observed., Conclusion: Both a triage checklist and a checklist plus limited obstetric ultrasound improved accurate identification of cases with some increase in false positive diagnosis. These interventions may be beneficial in a resource-limited maternity triage setting to improve midwives' diagnoses and clinical decision-making., Competing Interests: Declaration of Competing Interest The authors of this study have no financial conflicts of interest to report., (Copyright © 2021.

- Abstract
Myocardial infarction (MI) is one of the leading causes of death worldwide, and inflammation is central to tissue response and patient outcomes. The 18-kDa translocator protein (TSPO) has been used in PET as an inflammatory biomarker. The aims of this study were to screen novel, fluorinated, TSPO radiotracers for susceptibility to the rs6971 genetic polymorphism using in vitro competition binding assays in human brain and heart; assess whether the in vivo characteristics of our lead radiotracer,
18 F-LW223, are suitable for clinical translation; and validate whether18 F-LW223 can detect macrophage-driven inflammation in a rat MI model. Methods: Fifty-one human brain and 29 human heart tissue samples were screened for the rs6971 polymorphism. Competition binding assays were conducted with3 H-PK11195 and the following ligands: PK11195, PBR28, and our novel compounds (AB5186 and LW223). Naïve rats and mice were used for in vivo PET kinetic studies, radiometabolite studies, and dosimetry experiments. Rats underwent permanent coronary artery ligation and were scanned using PET/CT with an invasive input function at 7 d after MI. For quantification of PET signal in the hypoperfused myocardium, K1 (rate constant for transfer from arterial plasma to tissues) was used as a surrogate marker of perfusion to correct the binding potential for impaired radiotracer transfer from plasma to tissue (BPTC ). Results: LW223 binding to TSPO was not susceptible to the rs6971 genetic polymorphism in human brain and heart samples. In rodents,18 F-LW223 displayed a specific uptake consistent with TSPO expression, a slow metabolism in blood (69% of parent at 120 min), a high plasma free fraction of 38.5%, and a suitable dosimetry profile (effective dose of 20.5-24.5 μSv/MBq).18 F-LW223 BPTC was significantly higher in the MI cohort within the infarct territory of the anterior wall relative to the anterior wall of naïve animals (32.7 ± 5.0 vs. 10.0 ± 2.4 cm3 /mL/min, P ≤ 0.001). Ex vivo immunofluorescent staining for TSPO and CD68 (macrophage marker) resulted in the same pattern seen with in vivo BPTC analysis. Conclusion:18 F-LW223 is not susceptible to the rs6971 genetic polymorphism in in vitro assays, has favorable in vivo characteristics, and is able to accurately map macrophage-driven inflammation after MI., (© 2021 by the Society of Nuclear Medicine and Molecular Imaging.)- Published

- Abstract
Objective: To test whether introduction of a midwife-performed triage checklist and focused ultrasound improves diagnosis and referral for obstetric conditions, including multiple gestation, placenta previa, oligohydramnios, preterm birth, malpresentation, and abnormal fetal heart rate., Methods: We implemented an intake log (Phase 1), a checklist (Phase 2), and a checklist plus ultrasound scan (Phase 3) at three primary health centers in Eastern Uganda for women presenting in labor. Intake diagnoses, referral status, and delivery outcomes were assessed, as well as sensitivity and positive predictive value (PPV)., Results: Between February 2018 and July 2019, 1155, 961, and 603 women were enrolled across the three phases (n=2719); 2339 had outcome data. Incidence of any outcome-confirmed condition was 8.8%, 7.9%, and 7.1% (P=0.526) for each phase, respectively. The proportion of referred women with a condition did not change between Phases 1 and 2 (7.8% versus 8.6%, P=0.855), but increased in Phase 3 (48.4%, P<0.001). Sensitivity improved with each intervention; PPV decreased with ultrasound., Conclusion: Use of ultrasound plus checklist increased referrals and sensitivity for high-risk conditions, with decreased PPV. The checklist alone improved correct diagnosis, but not referral. Further evaluation of these triage interventions to maximize diagnostic accuracy, referral decisions, and outcomes are warranted., (© 2020 The Authors.

- Abstract
Background: Research on group antenatal care in low- and middle-income contexts suggests high acceptability and preliminary implementation success., Methods: We studied the effect of group antenatal care on gestational age at birth among women in Rwanda, hypothesizing that participation would increase mean gestational length. For this unblinded cluster randomized trial, 36 health centers were pair-matched and randomized; half continued individual antenatal care (control), half implemented group antenatal care (intervention). Women who initiated antenatal care between May 2017 and December 2018 were invited to participate, and included in analyses if they presented before 24 weeks gestation, attended at least two visits, and their birth outcome was obtained. We used a generalized estimating equations model for analysis., Findings: In total, 4091 women in 18 control clusters and 4752 women in 18 intervention clusters were included in the analysis. On average, women attended three total antenatal care visits. Gestational length was equivalent in the intervention and control groups (39.3 weeks (SD 1.6) and 39.3 weeks (SD 1.5)). There were no significant differences between groups in secondary outcomes except that more women in control sites attended postnatal care visits (40.1% versus 29.7%, p = 0.003) and more women in intervention sites attended at least three total antenatal care visits (80.7% versus 71.7%, p = 0.003). No harms were observed., Interpretation: Group antenatal care did not result in a difference in gestational length between groups. This may be due to the low intervention dose. We suggest studies of both the effectiveness and costs of higher doses of group antenatal care among women at higher risk of preterm birth. We observed threats to group care due to facility staff shortages; we recommend studies in which antenatal care providers are exclusively allocated to group antenatal care during visits., Trial Registration: ClinicalTrials.gov NCT03154177., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: Over 90,000 rescue and recovery responders to the September 2001 World Trade Center (WTC) attacks were exposed to toxic materials that can impair cardiac function and increase cardiovascular disease (CVD) risk. We examined WTC-related exposures association with annual and cumulative CVD incidence and risk over 17 years in the WTC Health Program (HP) General Responder Cohort (GRC)., Methods: Post 9/11 first occurrence of CVD was assessed in 37,725 responders from self-reported physician diagnosis of, or current treatment for, coronary artery disease, myocardial infarction, stroke and/or congestive heart failure from WTCHP GRC monitoring visits. Kaplan-Meier estimates of CVD incidence used the generalized Wilcoxon test statistic to account for censored data. Cox proportional hazards regression analyses estimated the CVD hazard ratio associated with 9/11/2001 arrival in responders with and without dust cloud exposure, compared with arrival on or after 9/12/2001. Additional analyses adjusted for comorbidities., Results: To date, 6.3% reported new CVD. In covariate-adjusted analyses, men's CVD 9/11/2001 arrival risks were 1.40 (95% confidence interval [CI] = 1.26, 1.56) and 1.43 (95% CI = 1.29, 1.58) and women's were 2.16 (95% CI = 1.49, 3.11) and 1.59 (95% CI = 1.11, 2.27) with and without dust cloud exposure, respectively. Protective service employment on 9/11 had higher CVD risk., Conclusions: WTCHP GRC members with 9/11/2001 exposures had substantially higher CVD risk than those initiating work afterward, consistent with observations among WTC-exposed New York City firefighters. Women's risk was greater than that of men's. GRC-elevated CVD risk may also be occurring at a younger age than in the general population., (© 2020 Wiley Periodicals LLC.)

- Abstract
Background: Although gains in newborn survival have been achieved in many low-income and middle-income countries, reductions in stillbirth and neonatal mortality have been slow. Prematurity complications are a major driver of stillbirth and neonatal mortality. We aimed to assess the effect of a quality improvement package for intrapartum and immediate newborn care on stillbirth and preterm neonatal survival in Kenya and Uganda, where evidence-based practices are often underutilised., Methods: This unblinded cluster-randomised controlled trial was done in western Kenya and eastern Uganda at facilities that provide 24-h maternity care with at least 200 births per year. The study assessed outcomes of low-birthweight and preterm babies. Eligible facilities were pair-matched and randomly assigned (1:1) into either the intervention group or the control group. All facilities received maternity register data strengthening and a modified WHO Safe Childbirth Checklist; facilities in the intervention group additionally received provider mentoring using PRONTO simulation and team training as well as quality improvement collaboratives. Liveborn or fresh stillborn babies who weighed between 1000 g and 2500 g, or less than 3000 g with a recorded gestational age of less than 37 weeks, were included in the analysis. We abstracted data from maternity registers for maternal and birth outcomes. Follow-up was done by phone or in person to identify the status of the infant at 28 days. The primary outcome was fresh stillbirth and 28-day neonatal mortality. This trial is registered with ClinicalTrials.gov, NCT03112018., Findings: Between Oct 1, 2016, and April 30, 2019, 20 facilities were randomly assigned to either the intervention group (n=10) or the control group (n=10). Among 5343 eligible babies in these facilities, we assessed outcomes of 2938 newborn and fresh stillborn babies (1447 in the intervention and 1491 in the control group). 347 (23%) of 1491 infants in the control group were stillborn or died in the neonatal period compared with 221 (15%) of 1447 infants in the intervention group at 28 days (odds ratio 0·66, 95% CI 0·54-0·81). No harm or adverse effects were found., Interpretation: Fresh stillbirth and neonatal mortality among low-birthweight and preterm babies can be decreased using a package of interventions that reinforces evidence-based practices and invests in health system strengthening., Funding: Bill & Melinda Gates Foundation., (Copyright © 2020 The Author(s).

- Abstract
Introduction: As facility-based deliveries increase globally, maternity registers offer a promising way of documenting pregnancy outcomes and understanding opportunities for perinatal mortality prevention. This study aims to contribute to global quality improvement efforts by characterizing facility-based pregnancy outcomes in Kenya and Uganda including maternal, neonatal, and fetal outcomes at the time of delivery and neonatal discharge outcomes using strengthened maternity registers., Methods: Cross sectional data were collected from strengthened maternity registers at 23 facilities over 18 months. Data strengthening efforts included provision of supplies, training on standard indicator definitions, and monthly feedback on completeness. Pregnancy outcomes were classified as live births, early stillbirths, late stillbirths, or spontaneous abortions according to birth weight or gestational age. Discharge outcomes were assessed for all live births. Outcomes were assessed by country and by infant, maternal, and facility characteristics. Maternal mortality was also examined., Results: Among 50,981 deliveries, 91.3% were live born and, of those, 1.6% died before discharge. An additional 0.5% of deliveries were early stillbirths, 3.6% late stillbirths, and 4.7% spontaneous abortions. There were 64 documented maternal deaths (0.1%). Preterm and low birthweight infants represented a disproportionate number of stillbirths and pre-discharge deaths, yet very few were born at ≤1500g or <28w. More pre-discharge deaths and stillbirths occurred after maternal referral and with cesarean section. Half of maternal deaths occurred in women who had undergone cesarean section., Conclusion: Maternity registers are a valuable data source for understanding pregnancy outcomes including those mothers and infants at highest risk of perinatal mortality. Strengthened register data in Kenya and Uganda highlight the need for renewed focus on improving care of preterm and low birthweight infants and expanding access to emergency obstetric care. Registers also permit enumeration of pregnancy loss <28 weeks. Documenting these earlier losses is an important step towards further mortality reduction for the most vulnerable infants., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
An investigation into the mechanism of Cu-catalyzed aryl boronic acid halodeboronation using electrophilic halogen reagents is reported. Evidence is provided to show that this takes place via a boronate-driven ipso-substitution pathway and that Cu is not required for these processes to operate: general Lewis base catalysis is operational. This in turn allows the rational development of a general, simple, and effective base-catalyzed halodeboronation that is amenable to the preparation of
125 I-labeled products for SPECT applications.- Published

- Abstract
Objective: To determine whether oral clindamycin reduces the risk of preterm birth (PTB) in women with abnormal vaginal microflora as evidenced by a vaginal pH ≥5.0., Design: Randomised double-blind placebo-controlled trial., Setting: Rural southern India., Population: Pregnant women with a singleton fetus between 13
+0/7 weeks and 20+6/7 weeks., Methods: Pregnant women were recruited during prenatal visits in Karnataka, India, from October 2013 to July 2015. Women were required to have a singleton fetus between 13+0/7 weeks and 20+6/7 weeks and an elevated vaginal pH (≥5.0) by colorimetric assessment. Participants were randomised to either oral clindamycin 300 mg twice daily for 5 days or an identical-appearing placebo., Main Outcome Measures: The primary outcome was the incidence of PTB, defined as delivery before 37+0/7 weeks., Results: Of the 6476 screened women, 1727 women were randomised (block randomised in groups of six; clindamycin n = 866, placebo n = 861). The demographic, reproductive, and anthropomorphometric characteristics of the study groups were similar. Compliance was high, with over 94% of capsules being taken. The rate of PTB before 37 weeks was comparable between the two groups [clindamycin 115/826 (13.9%) versus placebo 111/806 (13.8%), between-group difference 0.2% (95% CI -3.2 to 3.5%, P = 0.93)], as was PTB at less than 34 weeks [clindamycin 40/826 (4.8%) versus placebo group 37/806 (4.6%), between-group difference 0.3% (95% CI -1.8 to 2.3%, P = 0.81)]. No differences were detected in the incidence of birthweight of<2500 g, <1500 g, miscarriage, stillbirth or neonatal death., Conclusion: In this setting, oral clindamycin did not decrease PTB among women with vaginal pH ≥5.0., Tweetable Abstract: Oral clindamycin between 13+0/7 and 20+6/7 weeks does not prevent preterm birth in women with a vaginal pH ≥5.0., (© 2018 Royal College of Obstetricians and Gynaecologists.)- Published

- Abstract
Introduction Nigeria contributes more obstetric, postpartum and neonatal deaths and stillbirths globally than any other country. The Clinton Health Access Initiative in partnership with the Nigerian Federal Ministry of Health and the state Governments of Kano, Katsina, and Kaduna implemented an integrated Maternal and Neonatal Health program from July 2014. Up to 90% women deliver at home in Northern Nigeria, where maternal mortality ratio and neonatal mortality rates (MMR and NMR) are high and severe challenges to improving survival exist. Methods Community-based leaders ("key informants") reported monthly vital events. Pre-post comparisons of later (months 16-18) with conservative baseline (months 7-9) rates were used to assess change in MMR, NMR, perinatal mortality (PMR) and stillbirth. Two-tailed cross-tabulations and unadjusted and adjusted logistic regression analyses were conducted. Results Data on 147,455 births (144,641 livebirths and 4275 stillbirths) were analyzed. At endline (months 16-18), MMR declined 37% (OR 0.629, 95% CI 0.490-0.806, p ≤ 0.0003) vs. baseline 440/100,000 births (months 7-9). NMR declined 43% (OR 0.574, 95% CI 0.503-0.655, p < 0.0001 vs. baseline 15.2/1000 livebirths. Stillbirth rates declined 15% (OR 0.850, 95% CI 0.768-0.941, p = 0.0018) vs. baseline 21.1/1000 births. PMR declined 27% (OR 0.733, 95% CI 0.676-0.795, p < 0.0001) vs. baseline 36.0/1000 births. Adjusted results were similar. Discussion The findings are similar to the Cochrane Review effects of community-based interventions and indicate large survival improvements compared to much slower global and flat national trends. Key informant data have limitations, however, their limitations would have little effect on the results magnitude or significance.

Background: Second-generation endometrial ablation has been demonstrated safe for abnormal uterine bleeding treatment, in premenopausal women who have completed childbearing, in short-stay surgical centers and in physicians' offices. However, no standard regarding anesthesia exists, and practice varies depending on physician or patient preference and hospital policy and setting., Objective: The aim of this study was to evaluate whether local anesthetic, in combination with general anesthesia, affects postoperative pain and associated narcotic use following endometrial ablation., Materials and Methods: This was a single-center single-blind randomized controlled trial conducted in an academic-affiliated community hospital. A total of 84 English-speaking premenopausal women, aged 30 to 55 years, who were undergoing outpatient endometrial ablation for benign disease were randomized to receive standardized paracervical injection of 20 mL 0.25% bupivacaine (treatment group) or 20 mL normal saline solution (control group) upon completion of ablation. The study was designed to test a 40% 1-hour mean visual analog scale (VAS) pain score difference with an average standard deviation of 75% of both groups' mean VAS scores, using a 2-tailed test, a type I error of 5%, and statistical power of 80%. A sample of 36 patients per study group was required. Assuming a 15% attrition rate, the study enrolled 42 patients per study arm randomized in blocks of 2 (84 total). Two-tailed cross-tabulations with Fisher exact significance values where appropriate and Student t tests were used to compare patient characteristics. Backward stepwise regressions were conducted to control for confounding., Results: Between April 2016 and February 2017, a total of 108 women scheduled for endometrial ablation were screened (refusals, n = 21; ineligible, n = 3) to determine whether there were meaningful differences in postoperative VAS pain scores and postoperative narcotic use. Of the 84 randomized women, 2 age-ineligible women were excluded. Intent-to-treat analyses included 1 incorrect randomization (in which the provider consciously decided to provide analgesia regardless of the protocol, after which the provider was excluded from further study participation) and 3 women having no ablation because of operative difficulties. Three were lost to second-day follow-up. Treatment group patients (n = 41) experienced 1.3 points lower 1-hour postoperative VAS pain scores than the control group (n = 41, P = .02). The difference diminished by 4 hours (P = .31) and was negligible by 8 hours (P = .62). Treatment group patients used 3.6 less morphine equivalents of postoperative pain medication (P = .05). Regression analyses controlled for confounding reduced the 1-hour postoperative treatment group pain score difference to 0.8 (confidence interval [CI], -0.6 to 0.1) but slightly increased the average postoperative morphine equivalents to 3.7 (CI, -6.8 to -0.7)., Conclusion: This randomized controlled trial found that local anesthetic with low risk for complications, used in conjunction with general anesthesia, decreased postoperative pain at 1 hour and significantly reduced postoperative narcotic use following endometrial ablation. Further research is needed to determine whether the study results are generalizable and whether post procedure is the best time to administer the paracervical block to decrease endometrial ablation pain., (Copyright © 2017 Elsevier Inc.

- Abstract
Objective: We sought to analyze the published literature on bowel injuries in patients undergoing gynecologic robotic surgery with the aim to determine its incidence, predisposing factors, and treatment options., Data Sources: Studies included in this analysis were identified by searching PubMed Central, OVID Medline, EMBASE, Cochrane, and ClinicalTrials.gov databases. References for all studies were also reviewed. Time frame for data analysis spanned from November 2001 through December 2014., Study Eligibility Criteria: All English-language studies reporting the incidence of bowel injury or complications during robotic gynecologic surgery were included. Studies with data duplication, not in English, case reports, or studies that did not explicitly define bowel injury incidence were excluded., Study Appraisal and Synthesis Methods: The Guidelines for Meta-Analyses and Systematic Reviews of Observational Studies were used to complete the systematic review with the exception of scoring study quality and a single primary reviewer., Results: In all, 370 full-text articles were reviewed and 144 met the inclusion criteria. There were 84 bowel injuries recorded in 13,444 patients for an incidence of 1 in 160 (0.62%; 95% confidence interval, 0.50-0.76%). There were no significant differences in incidence of bowel injury by procedure type. The anatomic location of injury, etiology, and management were rarely reported. Of the bowel injuries, 87% were recognized intraoperatively and the majority (58%) managed via a minimally invasive approach. Of 13,444 patients, 3 (0.02%) (95% confidence interval, 0.01-0.07%) died in the immediate postoperative period and no deaths were a result of a bowel injury., Conclusion: The overall incidence of bowel injury in robotic-assisted gynecologic surgery is 1 in 160. When the location of bowel injuries were specified, they most commonly occurred in the colon and rectum and most were managed via a minimally invasive approach., (Copyright © 2016 Elsevier Inc.

- Abstract
Study Objectives: To evaluate the effectiveness of the porcine training model for obstetrics-gynecology (OB/GYN) residents in laparoscopic salpingectomy., Design: Randomized, controlled single-blinded trial., Classification: Canadian Task Force Classification I., Setting: A large community-based teaching hospital., Participants: All postgraduate year 1 through year 4 OB/GYN residents were enrolled (n = 22)., Intervention: All participants underwent a preintervention objective skills assessment test (OSAT), in which the participant performed live human laparoscopic salpingectomy. Residents were randomly assigned (using a computer-generated randomization table, in blocks of 2, stratified by ranked baseline OSAT scores) to the intervention or control group. The intervention group consisted of 1 educational session with presession assigned reading, a 40-min didactic lecture, viewing of a procedural video, and simulation and practice of laparoscopic salpingectomy on a porcine cadaver. The control group received traditional training per routine residency rotations., Measurements and Main Results: Laparoscopic salpingectomy was performed on live patients by study participants pre- and postintervention. These procedures were video recorded, and then scored by a single blinded evaluator of the OSATs. Nine pre- and postintervention OSAT indicators, reflecting provider knowledge and skill, were the primary outcome measures. Secondary outcomes were the changes in 10 subjective measures of comfort, assessed by a pre- and postintervention survey. The outcomes were assessed using 5-point Likert scales (for OSATs 1 = lowest score; for the subjective survey 1 = highest score). The control group OSAT scores did not change (pre: 26.6 ± 10.8, post: 26.2 ± 10.1; p = .65). There were significant improvements in 2-handed surgery (pre: 2.8 ± 1.6, post: 3.5 ± 1.3; p = .004) and use of energy (pre: 2.9 ± 1.3, post: 3.6 ± 1.0; p = .01) in the intervention group, contributing to an overall score change (pre: 26.7 ± 10.6, post: 29.9 ± 9.8; p ≤ .001). The control group had no change in comfort levels. The intervention group experienced both increases (anatomy, steps of surgery, 2-handed surgery, and use of energy) and decreases (reading and learning in operating room) in reported comfort levels., Conclusion: This study demonstrates that simulation can improve surgical technique OSATs. However, of 45 possible points, both groups' average scores were <70% of the optimum. Thus, the improvement, although statistically significant, was relatively small and indicates that further supplementation in training is needed to substantially increase the residents' surgical skills., (Copyright © 2016 AAGL.

- Abstract
Background: Access to injectable uterotonics for management of postpartum haemorrhage remains limited in Senegal outside health facilities, and misoprostol and oxytocin delivered via Uniject have been deemed viable alternatives in community settings. We aimed to compare the efficacy of these drugs when delivered by auxiliary midwives at maternity huts., Methods: We did an unmasked cluster-randomised controlled trial at maternity huts in three districts in Senegal. Maternity huts with auxiliary midwives located 3-21 km from the closest referral centre were randomly assigned (1:1; via a computer-generated random allocation overseen by Gynuity Health Projects) to either 600 μg oral misoprostol or 10 IU oxytocin in Uniject (intramuscular), stratified by reported previous year clinic volume (deliveries) and geographical location (inland or coastal). Maternity huts that had been included in a previous study of misoprostol for prevention of postpartum haemorrhage were excluded to prevent contamination. Pregnant women in their third trimester were screened for eligibility either during community outreach or at home-based prenatal visits. Only women delivered by the auxiliary midwives in the maternity huts were eligible for the study. Women with known allergies to prostaglandins or pregnancy complications were excluded. The primary outcome was mean change in haemoglobin concentration measured during the third trimester and after delivery. This study was registered with ClinicalTrials.gov, number NCT01713153., Findings: 28 maternity hut clusters were randomly assigned-14 to the misoprostol group and 14 to the oxytocin group. Between June 6, 2012, and Sept 21, 2013, 1820 women were recruited. 647 women in the misoprostol group and 402 in the oxytocin group received study drug and had recorded pre-delivery and post-delivery haemoglobin concentrations, and overall 1412 women delivered in the study maternity huts. The mean change in haemoglobin concentrations was 3·5 g/L (SD 16·1) in the misoprostol group and 2·7 g/L (SD 17·8) in the oxytocin group. When adjusted for cluster design, the mean difference in haemoglobin decreases between groups was not significant (0·3 g/L, 95% CI -8·26 to 8·92, p=0·71). Both drugs were well tolerated. Shivering was common in the misoprostol group, and nausea in the oxytocin group. Postpartum haemorrhage was diagnosed in one woman allocated to oxytocin, who was referred and transferred to a higher-level facility for additional care, and fully recovered. No other women were transferred., Interpretation: In terms of effects on haemoglobin concentrations, neither oxytocin nor misoprostol was significantly better than the other, and both drugs were safe and efficacious when delivered by auxiliary midwives. The programmatic limitations of oxytocin, including short shelf life outside the cold chain, mean that misoprostol could be more appropriate for community-level prophylaxis of postpartum haemorrhage., Funding: Bill & Melinda Gates Foundation., (Copyright © 2016 Diop et al.

- Abstract
Objectives: This study assessed whether community mobilization and interventions to improve emergency obstetric and newborn care reduced perinatal mortality (PMR) and neonatal mortality rates (NMR) in Belgaum, India., Methods: The cluster-randomised controlled trial was conducted in Belgaum District, Karnataka State, India. Twenty geographic clusters were randomized to control or the intervention. The intervention engaged and mobilized community and health authorities to leverage support; strengthened community-based stabilization, referral, and transportation; and aimed to improve quality of care at facilities., Results: 17,754 Intervention births and 15,954 control births weighing ≥1000 g, respectively, were enrolled and analysed. Comparing the baseline period to the last 6 months period, the NMR was lower in the intervention versus control clusters (OR 0.60, 95% CI 0.34-1.06, p = 0.076) as was the PMR (OR 0.74, 95% CI 0.46-1.19, p = 0.20) although neither reached statistical significance. Rates of facility birth and caesarean section increased among both groups. There was limited influence on quality of care measures., Conclusions for Practice: The intervention had large but not statistically significant effects on neonatal and perinatal mortality. Community mobilization and increased facility care may ultimately improve neonatal and perinatal survival, and are important in the context of the global transition towards institutional delivery.

- Abstract
Background: Skilled birth attendance and institutional delivery have been advocated for reducing maternal, perinatal and neonatal mortality (PMR and NMR). India has successfully implemented various strategies to promote skilled attendance and incentivize institutional deliveries in the last 5 years., Objectives: The study evaluates the trends in institutional delivery, PMR, NMR, and their risk factors in two Eunice Kennedy Shriver NICHD Global Network for Women's and Children's Health Research sites, in Belgaum and Nagpur, India, between January 2010 and December 2013., Design/methods: Descriptive data stratified by level of delivery care and key risk factors were analyzed for 36 geographic clusters providing 48 months of data from a prospective, population-based surveillance system that registers all pregnant permanent residents in the study area, and their pregnancy outcomes irrespective of where they deliver. Log binomial models with generalized estimating equations to control for correlation of clustered observations were used to test the trends significance, Results: 64,803 deliveries were recorded in Belgaum and 39,081 in Nagpur. Institutional deliveries increased from 92.6% to 96.1% in Belgaum and from 89.5% to 98.6% in Nagpur (both p<0.0001); hospital rates increased from 63.4% to 71.0% (p=0.002) and from 63.1% to 72.0% (p<0.0001), respectively. PMR declined from 41.3 to 34.6 (p=0.008) deaths per 1,000 births in Belgaum and from 47.4 to 40.8 (p=0.09) in Nagpur. Stillbirths also declined, from 22.5 to 16.3 per 1,000 births in Belgaum and from 29.3 to 21.1 in Nagpur (both p=0.002). NMR remained unchanged., Conclusions: Significant increases in institutional deliveries, particularly in hospitals, were accompanied by reductions in stillbirths and PMR, but not by NMR.

- Abstract
Objective: Many women stopped hormone therapy (HT) or estrogen therapy (ET) after the Women's Health Initiative results were published in 2002. This study assessed the incidence of hypertension, weight gain, and dyslipidemia; conditions that predispose to chronic diseases; medication use; and quality of life in women who used HT/ET for at least 5 years and subsequently stopped its use compared with those who continued its use., Methods: A retrospective study was conducted. All consenting eligible women (aged 56-73 y) in physicians' offices were interviewed, and measurements of weight, height, waist-to-hip ratio, and body fat were performed. Standardized quality-of-life and menopausal and medical questionnaires were administered. Three groups were compared: group 1, women who have remained on HT/ET; group 2, women who have resumed HT/ET after stopping for at least 6 months; and group 3, women who have stopped HT/ET and have not resumed., Results: One hundred fifty-nine women were enrolled in group 1, 43 women were enrolled in group 2, and 108 women were enrolled in group 3. Women's characteristics were similar, except that group 3 was 1.5 (0.5) years older and had 4.4 (0.7) years less HT/ET use than groups 1 and 2. Utian Quality of Life scores were significantly lower in group 3 (83.4 [12.5]) than in groups 1 and 2 (87.6 [13.3], P < 0.02), particularly in the occupational satisfaction scale. About 16.6% and 16.3% of women in groups 1 and 2 were on antihypertensive medication, respectively, compared with 27.4% in group 3 (P < 0.04)., Conclusions: Discontinuation of HT/ET may predispose some women to the risk of hypertension and may affect their quality of life.

- Abstract
There have been significant gains in improving maternal mortality over the last two decades. Researchers have suggested a variety of interventions and mechanisms to explain these improvements. While it is likely that much of what has been done in research and programs has contributed to this decline, the evidence regarding what works in the settings in which women deliver continues to face many challenges. We review the evidence for these improvements and suggest that there remain areas to focus on, particularly the births which currently take place in an unsupervised or substandard environments. We highlight the main areas where more evidence is needed, and end with a call to determine which of our interventions seem to have the most benefit; which do not; and where to invest future resources.

- Abstract
Background: The Heart Truth Professional Education Campaign was developed to facilitate education of health care providers in evidence-based strategies to prevent cardiovascular disease (CVD) in women., Methods: As part of the 3-year campaign, lectures based on the American Heart Association's evidence-based guidelines for CVD prevention in women were presented by local speakers to healthcare providers and students in three high-risk states: Delaware, Ohio, and New York. Participants' responses to pretest and posttest questions about CVD in women are presented. We performed t-test and multivariable linear regression to assess the influence of provider characteristics on baseline knowledge and knowledge change after the lecture., Results: Between 2008 and 2011, 2,995 healthcare providers, students, and other participants completed the baseline assessment. Knowledge scores at baseline were highest for physicians, with obstetrician/gynecologists scoring lowest (63%) and cardiologists highest (76%). Nurses had intermediate total knowledge (56%) and students had the lowest total knowledge (49%) at baseline. Pre- and post-lecture assessments were completed by 1,893 (63%) of attendees. Scores were significantly higher after the educational lecture (p ≤ .001), with greater increase for those with lower baseline scores. Baseline knowledge of the use of statins, hormone therapy, and antioxidants, as well as approaches to smoking cessation and treatment of hypertension, differed by provider type., Conclusion: Tailoring of lectures for non-physician audiences may be beneficial given differences in baseline knowledge. More emphasis is needed on statin use for all providers and on smoking cessation and treatment of hypertension for nurses, students, and other healthcare professionals., (Copyright © 2013 Jacobs Institute of Women's Health.

- Abstract
Objective: This study evaluated the effectiveness of Helping Babies Breathe (HBB) newborn care and resuscitation training for birth attendants in reducing stillbirth (SB), and predischarge and neonatal mortality (NMR). India contributes to a large proportion of the worlds annual 3.1 million neonatal deaths and 2.6 million SBs., Methods: This prospective study included 4187 births at >28 weeks' gestation before and 5411 births after HBB training in Karnataka. A total of 599 birth attendants from rural primary health centers and district and urban hospitals received HBB training developed by the American Academy of Pediatrics, using a train-the-trainer cascade. Pre-post written trainee knowledge, posttraining provider performance and skills, SB, predischarge mortality, and NMR before and after HBB training were assessed by using χ(2) and t-tests for categorical and continuous variables, respectively. Backward stepwise logistic regression analysis adjusted for potential confounding., Results: Provider knowledge and performance systematically improved with HBB training. HBB training reduced resuscitation but increased assisted bag and mask ventilation incidence. SB declined from 3.0% to 2.3% (odds ratio [OR] 0.76, 95% confidence interval [CI] 0.59-0.98) and fresh SB from 1.7% to 0.9% (OR 0.54, 95% CI 0.37-0.78) after HBB training. Predischarge mortality was 0.1% in both periods. NMR was 1.8% before and 1.9% after HBB training (OR 1.09, 95% CI 0.80-1.47, P = .59) but unknown status at 28 days was 2% greater after HBB training (P = .007)., Conclusions: HBB training reduced SB without increasing NMR, indicating that resuscitated infants survived the neonatal period. Monitoring and community-based assessment are recommended.

- Abstract
Objective: Sublingual misoprostol produces a rapid peak concentration, and is more effective than oral administration. We compared the postpartum measured blood loss with 400 μg powdered sublingual misoprostol and after standard care using 10 iu intramuscular (IM) oxytocin., Design: Double-blind randomised controlled trial., Setting: A teaching hospital: J N Medical College, Belgaum, India., Sample: A cohort of 652 consenting eligible pregnant women admitted to the labour room., Methods: Subjects were assigned to receive the study medications and placebos within 1 minute of clamping and cutting the cord by computer-generated randomisation. Chi-square and bootstrapped Student's t-tests were used to test categorical and continuous outcomes, respectively., Main Outcome Measures: Measured mean postpartum blood loss and haemorrhage (PPH, loss ≥ 500 ml), >10% pre- to post-partum decline in haemoglobin, and reported side effects., Results: The mean blood loss with sublingual misoprostol was 192 ± 124 ml (n=321) and 366 ± 136 ml with oxytocin IM (n=331, P ≤ 0.001). The incidence of PPH was 3.1% with misoprostol and 9.1% with oxytocin (P=0.002). No woman lost ≥ 1000 ml of blood. We observed that 9.7% and 45.6% of women experienced a haemoglobin decline of >10% after receiving misoprostol and oxytocin, respectively (P ≤ 0.001). Side effects were significantly greater in the misoprostol group than in the oxytocin group., Conclusion: Unlike other studies, this trial found sublingual misoprostol more effective than intramuscular oxytocin in reducing PPH, with only transient side effects being greater in the misoprostol group. The sublingual mode and/or powdered formulation may increase the effectiveness of misoprostol, and render it superior to injectable oxytocin for the prevention of PPH. Further research is needed to confirm these results., (© 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.)

- Abstract
Objective: To analyze the Ecuadorian experience regarding the adoption, scale-up, and institutionalization of active management of the third stage of labor (AMTSL) for prevention of postpartum hemorrhage via continuous quality improvement (CQI) processes., Methods: Average AMTSL implementation rates for women with vaginal deliveries were compared using unweighted provincial aggregate data from facilities participating in 3 phases of AMTSL programming. Months taken to implement AMTSL at 80% or more and 90% or more compliance were compared across phases., Results: Rate of oxytocin administration during the first 3 months was 5.0% in phase 1, 9.8% in phase 2, and 72.2% in phase 3 (P≤0.001 vs phases 1 and 2). The average number of months provinces took to increase oxytocin administration to 80% or more and 90% or in more women with vaginal deliveries was, respectively, 21.6±18.7 and 30.6±16.4 in phase 1, 23.5±15.1 and 30.1±14.9 in phase 2, and 4.7±4.9 (P≤0.01 vs phase 1; P≤0.001 vs phase 2) and 4.0±3.4 (P≤0.001 vs phases 1 and 2) in phase 3. By December 2009, AMTSL implementation was sustained at 90% or more in all provinces., Conclusion: CQI processes identified resistance and operational barriers, and developed mechanisms to overcome them., (Copyright © 2012 International Federation of Gynecology and Obstetrics.

- Abstract
With the ultimate goal of reducing maternal and neonatal mortality, many countries have recently adopted innovative financing mechanisms to encourage the use of professional maternal health services. The current study evaluates one such initiative - a pilot voucher program in Bangladesh. The program provides poor women with cash incentives and free access to antenatal, delivery, and postnatal care, as well as cash incentives for providers to offer these services. We conducted a household survey of 2208 women who delivered in the 6 months before the survey (conducted in 2009) in 16 intervention and 16 matched comparison sub-districts. Probit and linear regressions are used to analyze the effects of residing in voucher sub-districts on the use of professional maternal health services and associated out-of-pocket expenditures. Using information on birth history, we conducted sensitivity analyses employing difference-in-differences methods, comparing women's reported births before and after the program's initiation in the intervention and comparison sub-districts. We found that the program significantly increased the use of antenatal, delivery, and postnatal care with qualified providers. Compared to women in matched comparison sub-districts, women in intervention areas had a 46.4 percentage point higher probability of using a qualified provider and 13.6 percentage point higher probability of institutional delivery. They also paid approximately Taka 640 (US$ 9.43) less for maternal health services, equivalent to 64% of the sample's average monthly household expenditure per capita. No significant effect of vouchers was found on the rate of Cesarean section. Our findings therefore support voucher program expansion targeting the economically disadvantaged to improve the use of priority health services. The Bangladesh voucher program is a useful example for other developing countries interested in improving maternal health service utilization., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

- Abstract
Objective: To demonstrate that training ensures correct administration of oral misoprostol by auxiliary midwives for prevention of postpartum hemorrhage (PPH) among women giving birth at the community level in Senegal., Methods: A 6-day training program for auxiliary midwives and supervisors, including 1 day of PPH prevention training and a practicum of 10 deliveries at health centers and 3 deliveries at maternity huts, was conducted in 2 Senegalese districts in June-July 2009. Data were collected between July and December 2009 on the administration of oral misoprostol by trained auxiliary midwives among 245 women giving birth at health centers, health posts, and maternity huts., Results: All participating women received the correct administration of oral misoprostol; however, few women delivering in the community-based maternity huts received the supervision that is locally required to administer misoprostol. Women were willing to pay for some or all of the costs of misoprostol for PPH prevention., Conclusion: Timely management of PPH is essential to reduce maternal mortality. With limited training, auxiliary midwives achieved the correct administration of oral misoprostol that can attain this goal. Community delivery supervised by a skilled attendant limits access to, and need not be a requirement for, PPH prevention., (Copyright © 2011 International Federation of Gynecology and Obstetrics.

- Abstract
Objective: Immediate Kangaroo Mother Care (KMC), an intervention following childbirth whereby the newborn is placed skin-to-skin (STS) on mother's chest to promote thermal regulation, breastfeeding and maternal-newborn bonding, is being taught in very low-income countries to improve newborn health and survival. Existing data are reviewed to document the association between community-based KMC (CKMC) implementation and its potential benefits., Study Design: New analyses of the sole randomized controlled study of CKMC in Bangladesh and others' experiences with immediate KMC are presented., Result: Newborns held STS less than 7 h per day in the first 2 days of life do not experience substantially better health or survival than babies without being held STS., Conclusion: Most women who were taught CKMC hold their newborns STS, but do so in a token manner unlikely to improve health or survival. Serious challenges exist to provide effective training and postpartum support to achieve adequate STS practices. These challenges must be overcome before scaling up.

- Abstract
Background: Meta-analyses of postpartum blood loss and the effect of uterotonics are biased by visually estimated blood loss., Objectives: To conduct a systematic review of measured postpartum blood loss with and without prophylactic uterotonics for prevention of postpartum haemorrhage (PPH)., Search Strategy: We searched Medline and PubMed terms (labour stage, third) AND (ergonovine, ergonovine tartrate, methylergonovine, oxytocin, oxytocics or misoprostol) AND (postpartum haemorrhage or haemorrhage) and Cochrane reviews without any language restriction., Selection Criteria: Refereed publications in the period 1988-2007 reporting mean postpartum blood loss, PPH (> or =500 ml) or severe PPH (> or =1000 ml) following vaginal births., Data Collection and Analysis: Raw data were abstracted into Excel by one author and then reviewed by a co-author. Data were transferred to SPSS 17.0, and copied into RevMan 5.0 to perform random effects meta-analysis., Main Results: The distribution of average blood loss (29 studies) is similar with any prophylactic uterotonic, and is lower than without prophylaxis. Compared with no uterotonic, oxytocin and misoprostol have lower PPH (OR 0.43, 95% CI 0.23-0.81; OR 0.73, 95% CI 0.50-1.08, respectively) and severe PPH rates (OR 0.61, 95% CI 0.29-1.29; OR 0.74, 95% CI 0.52-1.04, respectively). Oxytocin has lower PPH (OR 0.65, 95% CI 0.60-0.70) and severe PPH (OR 0.71, 95% CI 0.56-0.91) rates than misoprostol, but not in developing countries., Conclusion: Oxytocin is superior to misoprostol in hospitals. Misoprostol substantially lowers PPH and severe PPH. A sound assessment of the relative merits of the two drugs is needed in rural areas of developing countries, where most PPH deaths occur.

- Abstract
Objective: We adapted kangaroo mother care for immediate postnatal community-based application in rural Bangladesh, where the incidence of home delivery, low birth weight, and neonatal and infant mortality is high and neonatal intensive care is unavailable. This trial tested whether community-based kangaroo mother care reduces the overall neonatal mortality rate by 27.5%, infant mortality rate by 25%, and low birth weight neonatal mortality rate by 30%., Methods: Half of 42 unions in 2 Bangladesh divisions with the highest infant mortality rates were randomly assigned to community-based kangaroo mother care, and half were not. One village per union was randomly selected proportionate to union population size. A baseline survey of 39,888 eligible consenting women collected sociodemographic information. Community-based workers were taught to teach community-based kangaroo mother care to all expectant and postpartum women in the intervention villages. A total of 4165 live births were identified and enrolled. Newborns were followed for 30 to 45 days and infants were followed quarterly through their first birthday to record infant care, feeding, growth, health, and vital status., Results: Forty percent overall and approximately 65% of newborns who died were not weighed at birth, and missing birth weight was differential by study group. There was no difference in overall neonatal mortality rate or infant mortality rate. Except for care seeking, community-based kangaroo mother care behaviors were more common in the intervention than control group, but implementation was weak compared with the pilot study., Conclusions: The extensive missing birth weight and its potential bias render the evidence insufficient to justify implementing community-based kangaroo mother care. Additional experimental research ensuring baseline comparability of mortality, adequate kangaroo mother care implementation, and birth weight assessment is necessary to clarify the effect of community-based kangaroo mother care on survival.

- Abstract
Essential obstetric care is promoted as the prime strategy to save women's lives in developing countries. We measured the effect of improving lifesaving skills (LSS) capacity in Vietnam, a country in which most women deliver in health facilities. A quasi-experimental study was implemented to assess the impact of LSS training and readiness (availability of essential obstetric equipment, supplies, and medication) on the diagnosis of life-threatening obstetric conditions and appropriate management of labor and birth. The intervention (LSS training and readiness) was provided to all clinics and hospitals from 1 of 3 demographically similar districts in southcentral Vietnam, to hospitals only in another district, with the third district serving as the comparison group. Detection of life-threatening obstetric conditions increased in both experimental clinics and hospitals, but the intervention only improved the management of these conditions in hospitals. Management of life-threatening obstetric conditions is most effective in hospitals. The intervention did not clearly benefit women delivering in clinics.

- Abstract
This study assessed the incidence of postpartum infection which is rarely clinically evaluated and is probably underestimated in developing countries. This prospective study identified infection after vaginal delivery by clinical and laboratory examinations prior to discharge from hospital and again at six weeks postpartum in Ho Chi Minh City, Viet Nam. Textbook definitions, physicians' diagnoses, symptomatic and verbal autopsy definitions were used for classifying infection. Logistic regression was used for determining associations of postpartum infection with socioeconomic and reproductive characteristics. In total, 978 consecutive, eligible consenting women were followed up at 42+/-7 (range 2-45) days postpartum (not associated with incidence). Ninety-eight percent took 'prophylactic' antibiotics. The most conservative estimate of the incidence of postpartum infection was 1.7%. The incidence of serious infection was 0.5%, but increased to 4.6% when verbal autopsy and symptomatic definitions were used. Postpartum infection, particularly serious infection, is greatly underestimated. Just preventing or treating infection could have a substantial impact on reducing maternal mortality in developing countries.

- Abstract
Objective: Working with a multidisciplinary team of Ecuadorians, Bangladeshis and Americans, we developed a simple protocol for community-based implementation of kangaroo mother care (CKMC) that does not require birth weight or clinical judgment to identify which newborns should receive CKMC. CKMC could stabilize newborns and possibly reduce neonatal mortality where there is little medical care for newborns and low birth weight (LBW) is common., Study Design: During their CKMC training, community-based workers identified 35 expectant or recently delivered women in the pilot study area and taught them about CKMC. Women were interviewed at 1 month postpartum to evaluate their experience with CKMC., Results: In all, 77% of mothers initiated skin-to-skin care and 85% with LBW babies did so (37% were LBW). CKMC mothers delayed newborn bathing. Few slept upright with their newborns., Conclusions: CKMC was quickly and popularly adopted. A randomized controlled cluster trial is planned to determine whether CKMC reduces neonatal mortality.

- Abstract
Measuring the impact of obstetric interventions on maternal mortality and/or morbidity is especially difficult in developing countries, where most maternal deaths occur. Therefore, program planning has been based on theory rather than proved effectiveness. After reviewing both the strategies that have been promoted to reduce maternal mortality and the adequacy of existing evidence used to justify their selection, the investigators highlight reasons why rigorous criteria for the selection and evaluation of interventions should be adopted. Adequate evaluation of intervention effectiveness under real-life conditions in developing countries is an efficient way to identify interventions for large-scale program replication and could speed progress in reducing maternal deaths.

- Abstract
Objectives: Prenatal iron supplementation has been the standard recommendation for reducing maternal anemia in developing countries for the past 30 years. This article reviews the efficacy of iron supplementation on hemoglobin levels in pregnant women in developing countries., Methods: Data from randomized controlled trials published between 1966 and 1998 were pooled. Meta-analyses of the relative change in maternal hemoglobin associated with iron supplementation were stratified by initial hemoglobin levels, duration of supplementation, and daily gestational supplement dose and supplementation with other nutrients., Results: Iron supplementation raises hemoglobin levels. Its effects are dose dependent and are related to initial hematologic status. The extent to which iron supplementation can reduce maternal anemia is unclear., Conclusions: The extent to which maternal hemoglobin levels can be increased by recommended prenatal supplementation is limited and has uncertain physiological benefits. Other approaches, including food fortification and prevention and treatment of other causes of anemia, require methodologically rigorous evaluation to find effective answers to this global problem.

- Abstract
This retrospective study assessed the utility of women's self-reports to identify obstetric complications in rural Ghana. All consenting obstetric and postpartum inpatients, presenting from the seventh month of gestation to 42 days postpartum, were interviewed at the Holy Family Hospital, Techiman and were asked about their signs and symptoms. A combination of clinical examination and laboratory testing of urine and blood samples was used for determining case status. Self-reported obstetric complications of 340 women were compared with the corresponding diagnostic status for their sensitivity, specificity, predictive value, and test-efficiency. Using algorithms that could not be practically applied at the community level, self-reported symptoms correctly identified the majority (75%) of complicated and uncomplicated pregnancies, but missed one-quarter of cases requiring emergency obstetric care. The positive predictive value of 50% indicates that women's self-reported symptoms should not be used in estimating the incidence of these conditions or in identifying women requiring referral in this population.

- Abstract
Objective: To reassess the practical value of verbal autopsy data, which, in the absence of more definitive information, have been used to describe the causes of maternal mortality and to identify priorities in programmes intended to save women's lives in developing countries., Methods: We reanalysed verbal autopsy data from a study of 145 maternal deaths that occurred in Guerrero, Querétaro and San Luis Potosí, Mexico, in 1995, taking into account other causes of death and the WHO classification system. The results were also compared with information given on imperfect death certificates., Findings: The reclassification showed wide variations in the attribution of maternal deaths to single specific medical causes., Conclusion: The verbal autopsy methodology has inherent limitations as a means of obtaining histories of medical events. At best it may reconfirm the knowledge that mortality among poor women with little access to medical care is higher than that among wealthier women who have better access to such care.

- Abstract
Objectives: This study measured the effect of information about family planning methods and STD risk factors and prevention, together with personal choice on the selection of intrauterine devices (IUDs) by clients with cervical infection., Methods: We conducted a randomised, controlled trial in which family planning clients were assigned to one of two groups, the standard practice (control) group in which the provider selected the woman's contraceptive and the information and choice (intervention) group. The study enrolled 2107 clients in a family planning clinic in Mexico City., Results: Only 2.1% of the clients had gonorrhoea or chlamydial infections. Significantly fewer women in the intervention group selected the IUD than the proportion for whom the IUD was recommended in the standard care group by clinicians (58.2% v 88.2%, p = 0.0000). The difference was even more pronounced among infected women: 47.8% v 93.2% (intervention v control group, p = 0.0006)., Conclusions: The intervention increased the selection of condoms and reduced the selection of IUDs, especially among women with cervical infections, for whom IUD insertion is contraindicated.

- Abstract
Objective: This quasi-experimental study tested a method to safely reduce the rate of cesarean delivery in Ecuador., Method: Hospital policy was modified to provide co-management for cesarean candidates at the major maternity hospital in Quito. Cesarean rates before (n=14743) and after (n=12351) the intervention were compared by chi-square and multiple logistic regression with other major maternity hospitals (before, n=12514; after, n=9590). Characteristics of cesarean candidates who had vaginal or cesarean deliveries in the intervention hospital were compared by chi-square (n=1584)., Result: Cesarean rates declined by 4.5% (P<0.001) in the intervention hospital. A smaller (2.1%, P<0.01) reduction occurred in the other major public hospital in Quito where students of the co-principal investigator attempted to reduce cesarean delivery. Cesarean rates were unchanged in the public maternity hospitals of other major cities., Conclusion: Case co-management, a simple, locally appropriate, and inexpensive intervention, safely reduced surgical delivery, hospital stay and cost of care.

- Abstract
The standard diagnostic tools to identify sexually transmitted infections are often expensive and have laboratory and infrastructure requirements that make them unavailable to family planning and primary health-care clinics in developing countries. Therefore, inexpensive, accessible tools that rely on symptoms, signs, and/or risk factors have been developed to identify and treat reproductive tract infections without the need for laboratory diagnostics. Studies were reviewed that used standard diagnostic tests to identify gonorrhea and cervical chlamydial infection among women and that provided adequate information about the usefulness of the tools for screening. Aggregation of the studies' results suggest that risk factors, algorithms, and risk scoring for syndromic management are poor indicators of gonorrhea and chlamydial infection in samples of both low and high prevalence and, consequently, are not effective mechanisms with which to identify or manage these conditions. The development and evaluation of other approaches to identify gonorrhea and chlamydial infections, including inexpensive and simple laboratory screening tools, periodic universal treatment, and other alternatives must be given priority.

- Abstract
Objectives: The prevalence of vitamin A deficiency has traditionally been assessed through xerophthalmia or biochemical surveys. The cost and complexity of implementing these methods limits the ability of nonresearch organizations to identify vitamin A deficiency. This study examined the validity of a simple, inexpensive food frequency method to identify areas with a high prevalence of vitamin A deficiency., Methods: The validity of the method was tested in 15 communities, 5 each from the Philippines, Guatemala, and Tanzania. Serum retinol concentrations of less than 20 micrograms/dL defined vitamin A deficiency., Results: Weighted measures of vitamin A intake six or fewer times per week and unweighted measures of consumption of animal sources of vitamin A four or fewer times per week correctly classified seven of eight communities as having a high prevalence of vitamin A deficiency (i.e., 15% or more preschool-aged children in the community had the deficiency) (sensitivity = 87.5%) and four of seven communities as having a low prevalence (specificity = 57.1%)., Conclusions: This method correctly classified the vitamin A deficiency status of 73.3% of the communities but demonstrated a high false-positive rate (42.9%).

- Abstract
Pregnant and non-pregnant women in Indramayu, West Java were examined for nutritional status, using anthropometric indicators. For the pregnant women, longitudinal data on nutritional status, iron consumption and weight gain were examined in relation to neonatal weight and length. Comparing the non-pregnant women's average nutritional status with reference tables for height, weight and MUAC, they placed at the 25th percentile or less on all indicators. Using original formulae to estimate pre-pregnancy weight and pregnancy weight gain, the study showed that 18% of pregnant women had a pre-pregnancy weight of under 40 kg and the average pregnancy weight gain was under 9 kg. Comparing estimated pregnancy weight gain with the amount of weight gain needed to compensate for generally low pre-pregnancy weight, only about 9% of women gained adequately. In multiple regression models that controlled for other maternal and neonatal factors, iron consumption during pregnancy was a significant predictor of full-term (37 weeks or more) neonatal weight (P = 0.01) and length (P = 0.01). Consumption of one or more tablets (200 mg ferrous sulfate and 0.25 mg folic acid) per week by women during pregnancy was associated with increased neonatal weight (by 172 g on average) and length (by 1 cm on average). Adequate weight gain during pregnancy and maternal height also contributed to the specification of the neonatal weight model (P = 0.07 for both). In the neonatal length model, maternal height was also nearly significant (P = 0.03). The same models did not explain the variability in neonatal weight and length in the pre-term group (< 37 weeks gestation).
