Humanitarian Mission at Home: Walter Reed National Military Medical Center's Experience in Operation Allies Refuge and Operation Allies Welcome.

Military medicine has a long history of humanitarian efforts globally, including responses to natural disasters and as planned medical civil action projects. However, ending two decades of war in Afghanistan, Walter Reed National Military Medical Center (WRNMMC) was tasked to receive up to 63 injured patients with less than 96-hour notice on August 27, 2021. As part of Operation Allies Refuge and transition to Operation Allies Welcome, this article highlights the complicated cross-organizational and multidisciplinary response at WRNMMC where ultimately 277 Afghan patients and nonmedical attendants received medical care and other requirements for resettlement. Lessons learned from coordinating the complex short suspense medical, cultural, and logistic efforts are noted as considerations and practical recommendations for future missions.

Mediastinal Mass Discovered in the Second Trimester, a Rare Presentation of Hodgkin's Lymphoma in Pregnancy.

Newly diagnosed malignancy during pregnancy is rare affecting approximately 1 in 1,000 pregnancies. Breast followed by hematologic malignancies are most common. Hodgkin's lymphoma (HL) is a lymphoid neoplasm which can present with lymphadenopathy or mediastinal mass and represents 6% of all malignancies diagnosed during pregnancy. Treatment involves a combination of chemotherapy with or without adjuvant radiation which poses significant challenges when diagnosed antepartum. We highlight a 28-year-old primigravida at 26 weeks gestation who presented to the emergency department in Japan with cough, dyspnea, and sore throat for 3-5 days. Initial chest radiography demonstrated a large perihilar mass with mediastinal shift. Follow-up CT chest revealed an anterior mediastinal mass measuring 8 cm × 19 cm × 16 cm with features concerning for aggressive lymphoma. The patient was subsequently transferred to a stateside tertiary care center for expedited workup. She underwent two core needle biopsies, both of which were non-diagnostic. Cardiothoracic surgery performed a cervical mediastinoscopy with excision of the enlarged right supraclavicular lymph node. Pathologic analysis revealed classical HL, nodular sclerosis subtype. Treatment was initiated with adriamycin, bleomycin, vinblastine, and dacarbazine with two cycles planned antepartum followed by additional cycles postpartum. The patient had an uncomplicated vaginal delivery at 38 weeks gestation. Diagnosis of HL in pregnancy is rare, and expedited diagnosis can be challenging as multiple diagnostic and treatment modalities may impact pregnancy. Management in pregnancy requires a multidisciplinary approach, and decisions regarding treatment and delivery timing should be weighed against risk to the fetus.

Complete Molar Pregnancies with a Coexisting Fetus: Pregnancy Outcomes and Review of Literature.

Objective The objective of the study was to review the obstetric outcomes of complete hydatidiform molar pregnancies with a coexisting fetus (CHMCF), a rare clinical entity that is not well described. Materials and Methods We performed a retrospective case series with pathology-confirmed HMCF. The cases were collected via solicitation through a private maternal-fetal medicine physician group on social media. Each contributing institution from across the United States ( n = 9) obtained written informed consent from the patients directly, obtained institutional data transfer agreements as required, and transmitted the data using a Health Insurance Portability and Accountability Act of 1996 (HIPAA) compliant modality. Data collected included maternal, fetal/genetic, placental, and delivery characteristics. For descriptive analysis, continuous variables were reported as median with standard deviation and range. Results Nine institutions contributed to the 14 cases collected. Nine (64%) cases of CHMCF were a product of assisted reproductive technology and one case was trizygotic. The median gestational age at diagnosis was 12 weeks and 2 days (9 weeks-19 weeks and 4 days), and over half were diagnosed in the first trimester. The median human chorionic gonadotropin (hCG) at diagnosis was 355,494 mIU/mL (49,770-700,486 mIU/mL). Placental mass size universally enlarged over the surveillance period. When invasive testing was performed, insufficient sample or no growth was noted in 40% of the sampled cases. Antenatal complications occurred in all delivered patients, with postpartum hemorrhage (71%) and hypertensive disorders of pregnancy (29%) being the most frequent outcomes. Delivery outcomes were variable. Four patients developed gestational trophoblastic neoplasia. Conclusion This series is the largest report of obstetric outcomes for CHMCF to date and highlights the need to counsel patients about the severe maternal and fetal complications in continuing pregnancies, including progression to gestational trophoblastic neoplastic disease. Key Points CHMCF is a rare obstetric complication and may be associated with the use of assisted reproductive technology.Universally, patients with CHMCF who elected to manage expectantly developed antenatal complications.The risk of developing gestational trophoblastic neoplasia after CHMCF is high, and termination of the pregnancy did not decrease this risk.

Establishing and Maintaining a Quality and Safety Program on Labor and Delivery.

There is no single framework for a successful obstetric patient safety program. However, there are ample resources for the important components needed to create a patient safety program. All labor and delivery units should formulate their own quality and safety program that is individualized to the patients and staff that they serve. Here we will lay out the infrastructure as has been supported by the literature and reinforced in our experience.

A Novel Approach to Serial Amnioinfusion in a Case of Premature Rupture of Membranes Near the Limit of Viability.

Prelabor rupture of the membranes (PROM) near the limit of viability is associated with significant risks for both mother and fetus. Preterm labor, intra-amniotic infection, and placental abruption are the immediate risks to the pregnancy; however, the fetus incurs additional risks related to the sequela of persistent oligohydramnios. Transabdominal intra-amniotic infusions have been studied. Results, suggesting that this intervention may prolong the latency period, and potentially, decrease pulmonary hypoplasia in surviving neonates without evidence of increasing risk of intra-amniotic infection. To our knowledge, the use of antibiotic-infused fluid has not been reported in this clinical scenario. Therefore, we present a case of a patient with PROM before the limit of viability who underwent serial transabdominal amnioinfusions with oxacillin-containing normal saline, which resulted in membrane resealing and neonatal survival with no additional maternal morbidity.

Postpartum depression and timing of spousal military deployment relative to pregnancy and delivery.

OBJECTIVE: This study aimed to determine the relationship between spousal deployment and postpartum depression diagnosis among U.S. military wives, accounting for the timing of deployment with respect to pregnancy and delivery. METHODS: A retrospective cohort study was conducted to evaluate the association between spousal deployment and postpartum depression among pregnant wives of active-duty service members. Electronic medical records for 161,454 births occurring between 2004 and 2009 were used to define postpartum depression. Three non-mutually exclusive exposure variables were created to categorize deployments as occurring before, during, or after the infant's delivery. A multivariable logistic regression model mutually adjusted for these exposure variables was fitted, producing an odds ratio for each of the three timing categories. RESULTS: A modest significant association was detected only in those whose husbands deployed in pregnancy and returned after delivery (i.e., deployed during delivery) [odds ratio (OR) 1.10, 95 % confidence interval (CI) 1.04-1.15]. An interactive effect between preexisting depression or anxiety and deployment during delivery was also detected in the data (OR 1.13, 95 % CI 1.07-1.20 for those without a preexisting diagnosis; OR 0.87, 95 % CI 0.80-0.95 for those with a preexisting diagnosis). CONCLUSION: Health care providers should continue to be aware of spousal deployment as a military-unique stressor in this population and rigorously screen for potential symptoms of postpartum depression, especially among those whose husbands are absent at delivery.

Lethal neonatal coagulopathy after maternal ingestion of a superwarfarin.

BACKGROUND: Brodifacoum, a superwarfarin, is a common household agent used for rodenticides. We present a case of maternal brodifacoum ingestion that resulted in neonatal death. CASE: A 19-year-old primigravid woman presented at 32 weeks of gestation with spontaneous mucosal bleeding. Her fetus showed evidence of acidosis on external fetal monitoring. Laboratory values were consistent with maternal coagulopathy. After correction of the coagulopathy, the patient was taken for urgent cesarean delivery. The neonate showed evidence of fetal coagulopathy and died at 4 days of life. CONCLUSION: Brodifacoum is a dangerous household chemical that, if ingested, can result in significant morbidity and mortality for both mother and neonate. Increased awareness of the serious and potentially lethal effects of brodifacoum is important.

Paraoxonase-1 concentrations in end-stage renal disease patients increase after hemodialysis: correlation with low molecular AGE adduct clearance.

BACKGROUND: Hemorrhagic stroke and ischemic heart disease continue to be key problems in patients with end stage renal failure. Reduced serum paraoxonase (PON-1) activity has been described in these patients, which could contribute to the accelerated development of atherosclerosis. We hypothesized that retention of uremic toxins and or "middle molecules" including advanced glycation (AGE) free adducts and peptides could play a mechanistic role in decreasing PON-1 activity. METHODS: We enrolled 22 ESRD patients undergoing hemodialysis in whom paired pre- and post-dialysis samples were studied along with 30 age-matched control subjects. RESULTS: ESRD patients showed a 76% decrease in PON-1 activity. As expected, ESRD patients had an increase in lipoperoxides and advanced oxidation protein products (AOPP). Our patients had a 3-fold increase in serum AGEs and a striking 10-fold increase in low molecular weight (<10 kDa) AGEs. Post-dialysis samples in all patients displayed an increase in PON-1 activity, which ranged from 4 to 40% of the predialysis value. HDL-cholesterol, apoAI, free cholesterol (as a LCAT surrogate), HDL-subclasses and TG did not change significantly after dialysis. Changes in PON-1 activity display a good correlation (r=0.66, p<0.001) with rates in which creatinine and urea are cleared. Clearance of low molecular weight AGEs after hemodialysis explains 79% of the changes in PON-1 activity and are hence a much better predictor than creatinine changes (r=0.89, p<0.00). In vitro incubation of paraoxonase with serum ultrafiltrates show a time and concentration dependent inhibition of PON-1 by the ultrafiltrates, an inhibition that is up to 3 times higher (from 8 to 24%) when chronic renal failure patients are the source of the ultrafiltrate. CONCLUSION: We showed that HD results in a significant, consistent increase in the activity of the antioxidant enzyme PON-1. The effect, correlates with the effectiveness of dialysis to clear creatinine and urea, and with the clearance of AGE adducts of low molecular weight. This effect was replicated in vitro, showing time and dose dependency. Our results suggest that another cause for the observed lower PON-1 concentrations in CRF are the retention of low-middle molecules and demonstrate a positive effect of hemodialysis in the delicate oxidant-antioxidant state of these patients, that should be weighted against other pro-oxidant effects that have also been shown to occur previously. If the hypothesis that AGEs are the main culprits is proved in further research, this opens a putative therapeutic avenue for AGE blockers in ESRD.
