Transient elastography and controlled attenuation parameter to evaluate hepatic steatosis and liver stiffness in postpartum patients.

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) affects 30% of adults in the United States. Transient elastography (TE) (Fibroscan, Echosens, Paris, France) with controlled attenuation parameter (CAP) is a noninvasive way to evaluate liver steatosis and liver stiffness. The primary objective of this study was to assess prevalence of elevated liver stiffness and steatosis immediately postpartum. Furthermore, we sought to evaluate whether there were differences in rates of metabolic disorders of pregnancy (gestational diabetes mellitus (GDM), gestational hypertension, and preeclampsia) and pre-pregnancy conditions (type 2 diabetes mellitus (DM), chronic hypertension, and obesity) in those with elevated postpartum liver steatosis/liver stiffness. METHODS: IRB approved prospective cross-sectional study in which TE and liver function tests were performed 1-2 days postpartum. CAP ≥300 dB/m was classified as significant steatosis. Increased liver stiffness was defined as ≥7 kPa. Prevalence was determined by proportion of individuals undergoing TE/CAP who met criteria. Chi-square analysis was used to compare differences between groups. RESULTS: Eighty-nine patients were included: 20 (22%) had GDM, 13 (15%) had gestational hypertension, and 15 (17%) had preeclampsia. Women with kPa ≥7 were more likely to have ALT ≥25, type 2 diabetes, and preeclampsia (p < .05). Pre-gravid BMI, BMI at delivery, and GDM were not associated with increased kPa. Pregravid BMI ≥25 and chronic hypertension were associated with CAP ≥ 300 dB/m (p < .05). GDM, preeclampsia, and gestational hypertension were not associated with CAP ≥300 dB/m. CONCLUSIONS: Patients with preeclampsia, type 2 diabetes, and elevated ALT were more likely to have elevated postpartum liver stiffness. Pregravid BMI ≥25 and ≥30 were associated with increased liver steatosis, although did not impact liver stiffness. GDM was not associated with increased liver stiffness or steatosis. Consideration should be made for screening pregnant patients with preeclampsia, type 2 DM and overweight or obese BMI for liver disease in the postpartum period with potential for lifestyle intervention.

Mirror syndrome in monochorionic diamniotic twins presenting as maternal hyponatremia: A case report.

This is a case report of a 39-year-old patient, G5P1031, with monochorionic diamniotic twins at 30 weeks and 1 day of gestation, who developed mirror syndrome without twin-to-twin transfusion syndrome (TTTS) with a unique presentation of maternal and neonatal hyponatremia. Coinciding with severe hyponatremia were maternal symptoms of edema, nausea and vomiting, hypoalbuminemia, elevated uric acid, as well as fetal selective growth restriction, polyhydramnios, umbilical artery absent end diastolic flow and prolonged bradycardia of twin B. Given the poor status of twin B and the risks to twin A, the patient underwent emergent cesarean delivery. Hyponatremia in all three patients resolved in the following 48-72 h. Mirror syndrome is associated with significant maternal and fetal morbidity and mortality. In this case, severe hyponatremia posed additional risks. Therefore, electrolyte monitoring should be considered in both mother and neonate(s).

Maternal Parvovirus B19 Infection Causing First-Trimester Increased Nuchal Translucency and Fetal Hydrops.

This is a case report of a 31-year-old primigravida who was diagnosed with an asymptomatic acute parvovirus B19 infection in the second trimester of pregnancy and its suspected association with an increased nuchal translucency (NT) measurement. Parvovirus B19 is a single-stranded DNA virus that is cytotoxic to erythroid progenitor cells, causing inhibition of erythropoiesis. While maternal disease is usually mild, fetal infection can result in spontaneous abortion, aplastic anemia, nonimmune fetal hydrops, and fetal demise. This fetus had an increased NT of 3.2 mm at 11 weeks' gestation with a normal male karyotype and microarray analysis on chorionic villi sampling, in addition to a normal fetal echocardiogram at 15 weeks' gestation. The anatomy scan at 20 weeks' and 1-day gestation revealed fetal ascites, pleural effusion, and increased middle cerebral artery peak systolic velocity suspicious for fetal anemia. At this time, maternal serology for parvovirus was positive for IgM and IgG. Amniocentesis, cordocentesis, and intrauterine transfusion were performed. The amniocentesis revealed elevated parvovirus B19 DNA, quantitative PCR (2,589,801 copies/mL, reference range <100 copies/mL). The patient delivered a viable male fetus at 37 weeks' and 6-day gestation, without sequelae of the previously noted hydrops. Parvovirus B19 infection should be a consideration when evaluating increased NT and hydrops fetalis. It warrants close antepartum surveillance and possible intrauterine fetal transfusions. With prompt recognition, proper treatment, and surveillance, these patients can go on to achieve healthy term deliveries. Long-term outcomes of delivered infants require further study.

Antegrade versus retrograde nailing techniques and trochanteric versus piriformis intramedullary nailing entry points for femoral shaft fractures: a systematic review and meta-analysis.

BACKGROUND: There are several different techniques commonly used to perform intramedullary (IM) nailing of the femur to fix femoral fractures. We sought to identify significant differences in outcomes of studies comparing 1) trochanteric and piriformis entry and 2) antegrade and retrograde entry in IM nailing of the femur. METHODS: We searched MEDLINE, Cochrane and Embase databases and the Orthopaedic Trauma Association and American Academy of Orthopaedic Surgeons websites for comparative studies published from inception to November 2015. Criteria used to select articles for detailed review included use of antegrade and retrograde entry point or use of trochanteric and piriformis entry point for IM nailing of the femur in adult patients. Functional and technical outcomes were extracted from accepted studies. RESULTS: We identified 483 potential studies, of which 52 were eligible. Of these, we included 13 publications and 2 abstracts (2 level I, 7 level II and 6 level III studies). Trochanteric entry significantly reduced operative duration by 14 min compared with piriformis entry (p = 0.030). Retrograde nailing had a greater risk of postoperative knee pain than antegrade nailing (p = 0.05). On the other hand, antegrade nailing had significantly more postoperative hip pain (p = 0.003) and heterotopic ossification (p < 0.001) than retrograde nailing. No significant differences in functional outcomes were observed. CONCLUSION: Although some significant differences were found, the varying quality of studies made recommendation difficult. Our meta-analysis did not confirm superiority of either antegrade over retrograde or trochanteric over piriformis entry for IM nailing of the femur. LEVEL OF EVIDENCE: Level III therapeutic.

CONTEXTE: Plusieurs techniques différentes sont couramment utilisées pour l'enclouage intramédullaire (IM) du fémur afin d'immobiliser les fractures fémorales. Nous avons voulu dégager les différences significatives sur le plan des résultats d'études ayant comparé 1) l'entrée par le trochanter et par la fossette piriforme et 2) l'entrée par voies antérograde et rétrograde pour l'enclouage IM du fémur. MÉTHODES: Nous avons interrogé les bases de données MEDLINE, Cochrane et EMBASE et les sites Web de l'Orthopaedic Trauma Association et de l'American Academy of Orthopaedic Surgeons pour recenser les études comparatives publiées depuis leur création et jusqu'en novembre 2015. Les critères utilisés pour la sélection des articles en vue d'un examen détaillé incluaient l'utilisation de points d'entrée antérograde et rétrograde ou du trochanter et de la fossette piriforme pour l'enclouage IM du fémur chez des patients adultes. Les résultats fonctionnels et techniques ont été dégagés des études retenues. RÉSULTATS: Nous avons recensé 483 études potentielles, dont 52 se sont révélées admissibles. Parmi elles, nous avons inclus 13 publications et 2 résumés (2 études de niveau I, 7 de niveau II et 6 de niveau III). Le point d'entrée par le trochanter a significativement réduit la durée des interventions, soit de 14 min, comparativement à l'entrée par la fossette piriforme (p = 0,030). L'enclouage rétrograde a comporté un risque plus élevé de douleur postopératoire au genou comparativement à l'enclouage antérograde (p = 0,05). Par ailleurs, l'enclouage antérograde a donné lieu à significativement plus de douleur à la hanche (p = 0,003) et d'ossification hétérotopique (p < 0,001) postopératoires comparativement à l'enclouage rétrograde. Aucune différence significative n'a été observée sur le plan des résultats fonctionnels. CONCLUSION: Même si nous avons noté quelques différences significatives, la qualité variable des études nous empêche de formuler des recommandations. Notre métaanalyse n'a pas confirmé la supériorité du point d'entrée antérograde plutôt que rétrograde ou par le trochanter plutôt que par la fossette piriforme pour l'enclouage IM du fémur. NIVEAU DE PREUVE: Niveau III thérapeutique.

A comparison of the types of screening tool administration methods used for the detection of intimate partner violence: a systematic review and meta-analysis.

Intimate partner violence (IPV) is associated with significant health consequences for victims, including acute/chronic pain, depression, trauma, suicide, death, as well as physical, emotional, and mental harms for families and children. The objective of this systematic review and meta-analysis was to assess the rate of IPV disclosure in adult women (>18 years of age) with the use of three different screening tool administration methods: computer-assisted self-administered screen, self-administered written screen, and face-to-face interview screen. A comprehensive literature search was conducted in the MEDLINE, EMBASE, PsycINFO, CINAHL, Database of Abstracts of Reviews of Effectiveness, and the Cochrane library databases. We identified 746 potentially relevant articles; however, only 6 were randomized controlled trials (RCTs) and included for analysis. No significant differences were observed when women were screened in face-to-face interviews or with a self-administered written screen (Odds of disclosing: 1.02, 95% confidence interval [CI]: [0.77, 1.35]); however, a computer-assisted self-administered screen was found to increase the odds of IPV disclosure by 37% in comparison to a face-to-face interview screen (odds ratio: 0.63, 95% CI: [0.31, 1.30]). Disclosure of IPV was also 23% higher for computer-assisted self-administered screen in comparison to self-administered written screen (Odds of disclosure: 1.23, 95% CI: [0.0.92, 1.64]). The results of this review suggest that computer-assisted self-administered screens leads to higher rates of IPV disclosure in comparison to both face-to-face interview and self-administered written screens.
