RESUMO
OBJECTIVE: To describe prenatal and postnatal imaging findings of fetal adrenal hemorrhage (FAH) and its associated perinatal outcomes, including frequency of postnatal surgical intervention. METHOD: A systematic literature review of seven electronic databases was conducted from inception until January 2022, with 2008 articles identified reporting prenatally identified fetal adrenal masses. Studies with confirmed FAH diagnosis were included. Quality and risk assessment were evaluated. RESULTS: Thirty-five studies, including 102 FAH cases, were analyzed. FAH was commonly described as cystic (28/90, 31%), anechoic (25/90, 28%), or mixed echogenic (14/90, 16%) on ultrasound. Outcome data were available for 65 cases (64%) of FAH: 9% (6/65) resolved prenatally, 35% (23/65) resolved postnatally, 34% (22/65) regressed in size after birth, and 22% (14/65) persisted postnatally. Overall, 25% (16/65) of cases underwent postnatal surgical intervention. Neuroblastoma was suspected in all 16 surgical cases. Only one case (1/16, 6%) confirmed a cystic hematoma with microscopic islets of neuroblastoma in situ on pathology. CONCLUSION: Prenatal diagnosis of FAH is challenging due to the significant heterogeneity of ultrasound findings. Final pathology did not support the need for surgical intervention. Persistent postnatal FAH warrants shared decision making for further management based on the clinical presentation.

PURPOSE: To assess oncofertility content on fertility clinic websites as indicated by eight relevant keywords. Additionally, we sought to describe the relationship between oncofertility content and five predetermined clinic characteristics. METHODS: We examined 381 fertility clinic websites that are members of the Society for Associated Reproductive Technology (SART). Extracted data included clinic location, practice type (private vs academic), size (cycles/year), type of NCI designated center (cancer center vs comprehensive cancer center), and distance from the nearest NCI center. Additionally, we documented whether the clinic was located in a state mandating reproductive and infertility services and/or included fertility preservation for "iatrogenic infertility" as reported by the American Society for Reproductive Medicine (ASRM). Data were summarized using descriptive statistics and compared using chi-squared or t-test as appropriate. RESULTS: Of the 381 fertility clinic websites analyzed, 322 (85%) contained at least one oncofertility-related keyword. Most frequently used terms included cancer (79%) and fertility preservation (78%), while less frequently used terms included suppression (9.4%) and shielding (5.0%). Practices that initiated ≥ 501 cycles per year were more likely to mention one of the oncofertility keywords (OR 1.2; 95% CI 1.1-1.3). The associations of oncofertility website content with practice type, state-mandated fertility insurance coverage, and distance from an NCI-designated cancer center were not statistically significant. Large clinic size was the only predictive factor for inclusion of oncofertility website content. Further studies are required to evaluate whether inclusion of oncofertility content on clinic websites impacts the use of these services by patients with cancer. CONCLUSION: This is the first study correlating availability of oncofertility content on SART fertility clinic websites with consideration of geographic proximity to NCI designated cancer centers. Large clinic size was the only predictive factor for inclusion of oncofertility website content.

This objective of this systematic review was to estimate live birth rate and explore prognostic indicators in fetuses with 45,X karyotype and a posterior cystic hygroma (CH). Electronic databases were searched and studies reporting pregnancy outcomes (termination, spontaneous abortion, demise, or live birth) for fetuses with 45,X karyotype and a CH diagnosed on ultrasound were included. For cases of survival, CH characteristics, presence of hydrops fetalis, or concomitant anomalies, delivery details, and postnatal outcomes were summarized. A total of 95 studies, including 535 cases, met inclusion criteria: 285 (53.3%) pregnancies were terminated, 72 (13.5%) had spontaneous abortion or demise, 164 (30.7%) had unspecified pregnancy failure, and 14 (2.6%) were live births. Among live births with data available, all CH measured 2-7 cm, more than half were septate, and almost all regressed in size or eventually disappeared. Hydrops fetalis was noted in five cases. Of the eight live births with neonatal outcomes available, three neonates died shortly after birth and five survived past the neonatal period. This review suggests that diagnosis of CH in a 45,X fetus is associated with an estimated live birth rate of 2.6%, but only 1% survive to infancy. Prognosis appears to improve with CH regression.

OBJECTIVE: To ascertain demographic and clinical features of Parkinson disease (PD) associated with functional neurological features. METHODS: A standardised form was used to extract data from electronic records of 53 PD patients with associated functional neurological disorders (PD-FND) across eight movement disorders centres in the USA, Canada and Europe. These subjects were matched for age, gender and disease duration to PD patients without functional features (PD-only). Logistic regression analysis was used to compare both groups after adjusting for clustering effect. RESULTS: Functional symptoms preceded or co-occurred with PD onset in 34% of cases, nearly always in the most affected body side. Compared with PD-only subjects, PD-FND were predominantly female (68%), had longer delay to PD diagnosis, greater prevalence of dyskinesia (42% vs 18%; P=0.023), worse depression and anxiety (P=0.033 and 0.025, respectively), higher levodopa-equivalent daily dose (972±701 vs 741±559 mg; P=0.029) and lower motor severity (P=0.019). These patients also exhibited greater healthcare resource utilisation, higher use of [(123)I]FP-CIT SPECT and were more likely to have had a pre-existing psychiatric disorder (P=0.008) and family history of PD (P=0.036). CONCLUSIONS: A subtype of PD with functional neurological features is familial in one-fourth of cases and associated with more psychiatric than motor disability and greater use of diagnostic and healthcare resources than those without functional features. Functional manifestations may be prodromal to PD in one-third of patients.

Ataxia-telangiectasia is an autosomal recessive neurodegenerative disorder that was initially thought to present exclusively in childhood. With the discovery of the ATM gene, the phenotypic spectrum of the condition has expanded. This review elaborates the expanded phenomenology, including oculomotor apraxia and immunodeficiency, and estimates the presence of each movement disorder feature from previously reported literature. Initial manifestations of Ataxia-telangiectasia include cerebellar symptoms (67%), dystonia (18%), choreoathetosis (10%), and tremor (4%), with parkinsonism and myoclonus not reported as initial features. The prevalence of movement disorders during the course of the disease includes cerebellar symptoms (96%), dystonia (89%), parkinsonism (41%), choreoathetosis (89%), myoclonus (92%), and tremor (74%). Phenomenology and age of onset is modulated by presence of residual ATM kinase activity, with genotypes heavily truncating the ATM protein associated with the most severe phenotypes. Ataxia-telangiectasia commonly results in a spectrum of movement disorders beyond ataxia and telangiectasias. © 2018 International Parkinson and Movement Disorder Society.

The search for novel anticancer therapeutic agents is an urgent and important issue in medicinal chemistry. Here, we report on the biological activity of the copper-based bioinorganic complex Cu4 (2,4-di-tert-butyl-6-(1H-imidazo- [1, 10] phenanthrolin-2-yl)phenol)4]·10 CH3CN (2), which was tested in rat L6 myotubes, mouse NSC-34 motor neurone-like cells, and HepG-2 human liver carcinoma. Upon 96 h incubation, 2 exhibited a significant cytotoxic effect on all three types of cells via activation of two cell death mechanisms (apoptosis and necrosis). Complex 2 exhibited better potency and efficacy than the canonical cytotoxic drug cisplatin. Moreover, during shorter incubations, complex 2 demonstrated a significant SOD mimetic activity, and it was more effective and more potent than the well-known SOD mimetic TEMPOL. In addition, complex 2 was able to interact with DNA and, cleave DNA in the presence of sodium ascorbate. This study shows the potential of using polynuclear redox active compounds for developing novel anticancer drugs through SOD-mimetic redox pathways.

Classic motivational conflicts theory (Lewin, 1931) distinguishes between approach-approach, and avoidance-avoidance conflicts. Previous research has focused solely on testing the theory's prediction that avoidance-avoidance conflicts are more difficult to resolve than approach-approach ones, using outcome measures (decision time and self-reports). The theory, however, specifies a force-fields mechanism to account for this difference in conflict resolution difficulty, whereby avoidance-avoidance conflicts (compared to approach-approach ones) elicit more (a) oscillations and (b) return to the middle point between options. However, this force-fields mechanism has never been empirically tested, arguably due to a lack of the tools to do so. In five studies (N = 534 U.K. residents), we use mouse-tracking measures to provide insight into the force-fields mechanism. We show that the force-fields' mechanistic properties-oscillations and returns to the middle point-distinguish the two types of conflict and uniquely account for conflict resolution difficulty beyond standard conflict-strength measures. Moreover, we test a novel, theory-driven prediction and robustly show a differential pattern of increased oscillations as a function of the decision-maker's proximity to the decision options. Finally, we test a boundary condition moderating the influence of conflict type on both the force-fields' mechanistic properties and conflict resolution difficulty.

BACKGROUND: Treatment options for severe, refractory iron deficiency anemia are limited in pregnancy. OBJECTIVE: To review the available literature on the use of recombinant erythropoietin in the treatment of iron deficiency anemia in pregnancy. SEARCH STRATEGY: An electronic search of seven databases from inception to March 2022 was performed using a combination of keywords. SELECTION CRITERIA: We included all randomized controlled or observational studies of pregnant patients with iron deficiency anemia who received recombinant erythropoietin or control. The primary outcome was a change in hematologic parameters (hemoglobin or hematocrit) after treatment. Studies were appraised using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. DATA COLLECTION AND ANALYSIS: Data were summarized using narrative synthesis and descriptive statistics as appropriate. This study was registered with PROSPERO, CRD42022313328. MAIN RESULTS: Of 234 studies screened, five studies met the inclusion criteria and had sufficient data for analysis (n = 103 recombinant erythropoietin and n = 104 controls). All patients in the intervention group received iron supplementation (intravenous or oral) in addition to recombinant erythropoietin. All patients in the control group received iron supplementation (intravenous or oral) alone. As the result of variance between studies in inclusion criteria, the timing of repeat blood draws, and data reporting, a meta-analysis could not be performed. Three studies found that serial recombinant erythropoietin combined with iron supplementation was more effective at raising hematologic laboratory parameters (hemoglobin or hematocrit) than iron alone. One study reported no difference in hemoglobin or hematocrit levels between groups at day 28. However, patients in this study only received one dose of recombinant erythropoietin, whereas those in the other studies received serial doses. Another study also found no difference in hemoglobin levels by day 28, but patients in the recombinant erythropoietin group had lower hemoglobin levels at baseline and a more rapid rise in hemoglobin than iron alone. This is demonstrated by a more significant rise in hemoglobin at day 11 in the recombinant erythropoietin group than in the control group. CONCLUSIONS: Serial recombinant erythropoietin administration and iron supplementation may be more effective at treating refractory iron deficiency anemia in pregnancy than iron supplementation alone.
RESUMO
The seminal theory of motivational conflicts distinguishes between approach-approach (AP-AP) conflicts, in which a decision is made between desirable alternatives, and avoidance-avoidance (AV-AV) conflicts, in which a decision is made between undesirable alternatives. The behavioral differences between AP-AP and AV-AV conflicts are well documented: abundant research showed that AV-AV conflicts are more difficult to resolve than AP-AP ones. However, there is little to no research looking into the neural underpinnings of the differences between the two conflict types. Here, we show that midfrontal theta, an established neural marker of conflict, distinguished between the two conflict types such that midfrontal theta power was higher in AV-AV conflicts than in AP-AP conflicts. We further demonstrate that higher midfrontal theta power was associated with shorter decision times on a single-trial basis, indicating that midfrontal theta played a role in promoting successful controlled behavior. Taken together, our results show that AP-AP and AV-AV conflicts are distinguishable on the neural level. The implications of these results go beyond motivational conflicts, as they establish midfrontal theta as a measure of the continuous degree of conflict in subjective decisions.

BACKGROUND: Given the overlapping clinical indicators and lack of diagnostic testing, misdiagnosis of immune thrombocytopenic purpura and gestational thrombocytopenia in pregnancy may be common. Current recommendations suggest utilizing platelet nadir during pregnancy to guide diagnosis. OBJECTIVE: This study aimed to assess the accuracy of gestational thrombocytopenia and immune thrombocytopenic purpura diagnoses using pre- and postpregnancy platelet counts. STUDY DESIGN: This was a retrospective cohort study of patients diagnosed with gestational thrombocytopenia and immune thrombocytopenic purpura from January 2017 to December 2019. Platelet counts were extracted from charts and evaluated at several time periods, namely prepregnancy (within 5 years), during pregnancy, and postpartum (>6 weeks to 5 years). A diagnosis of gestational thrombocytopenia was considered inaccurate if platelet counts were <150,000/µL pre- or postpregnancy with no other apparent causes or if the platelet nadir dropped below 100,000/µL during pregnancy. A diagnosis of immune thrombocytopenic purpura was deemed inaccurate if pre- or postpregnancy platelet counts were >150,000/µL. The primary outcome was accuracy of gestational thrombocytopenia and immune thrombocytopenic purpura diagnoses in patients. Secondary outcomes included mean platelet counts during pregnancy and difference in mean platelet counts for patients with an accurate vs inaccurate diagnosis of gestational thrombocytopenia. Outcomes were summarized with descriptive statistics and compared using Student t tests. RESULTS: A total of 116 patients met the inclusion criteria of which 111 (96%) and 5 (4%) had gestational thrombocytopenia and immune thrombocytopenic purpura diagnoses, respectively. Platelet counts outside of pregnancy were available for 91 (82%) of the patients, and 66 (57%) had prepregnancy platelet counts available. Of the 91 patients, the diagnosis was considered accurate in 61 (67%) and 5 (100%) patients with gestational thrombocytopenia and immune thrombocytopenic purpura, respectively. Conversely, 30 of 35 (86%) patients with immune thrombocytopenic purpura were found to be inaccurately diagnosed with gestational thrombocytopenia after application of platelet thresholds. Among these 30 patients, 10 had a prepregnancy platelet count <150,000/µL, 12 had a postpartum platelet count <150,000/µL, 3 had a platelet count nadir <100,000/µL during pregnancy, and 7 met more than 1 criterion. Pre- and postpregnancy platelet counts and platelet count nadir differed significantly for patients with an accurate vs inaccurate diagnosis of gestational thrombocytopenia (P<.001). CONCLUSION: When pre- and postpregnancy platelet counts were checked, one-third of cases of gestational thrombocytopenia met the criteria for immune thrombocytopenic purpura and were thus incorrectly diagnosed during pregnancy. Prepregnancy platelet counts, available for most patients, should be considered when diagnosing gestational thrombocytopenia vs immune thrombocytopenic purpura.

OBJECTIVE: This study aimed to evaluate the effect of music on anxiety in patients undergoing cesarean delivery. DATA SOURCES: An electronic search of PubMed, CINAHL, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials was performed from inception to November 2020. STUDY ELIGIBILITY CRITERIA: Eligibility criteria included all randomized controlled trials of pregnant women undergoing cesarean delivery who were randomized to either the music intervention or control. Studies needed to measure preoperative, intraoperative, or postoperative anxiety via a visual analog scale, State-Trait Anxiety Inventory, or Zung Self-Rating Anxiety Scale, for inclusion. The primary outcome was intraoperative anxiety during cesarean delivery. Secondary outcomes included preoperative and postoperative anxiety, postoperative pain, postoperative opioid requirements, blood pressure, and heart rate. STUDY APPRAISAL AND SYNTHESIS METHODS: The methodologic quality of the included studies was evaluated using the Cochrane Handbook for Systematic Reviews of Interventions. A meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce a summary of treatment effects in terms of mean difference with 95% confidence intervals. A prespecified subgroup analysis of patients undergoing a scheduled or an unscheduled cesarean delivery was carried out for the main outcomes. RESULTS: Of the 1296 studies screened, 15 met the inclusion criteria (n=613 music group vs n=748 controls). Three trials (n=217 music group vs n=215 controls) reported on intraoperative anxiety specifically. Among studies using a visual analog scale for anxiety assessment, women in the intervention group had lower intraoperative anxiety levels than the controls (mean difference, -0.54; 95% confidence interval, -0.87 to -0.20; I2=0%; n=2 studies). One trial used the State-Trait Anxiety Inventory and 1 trial used the Zung Self-Rating Anxiety Scale for intraoperative anxiety assessment. In both of these studies, music exposure was associated with lower anxiety levels when compared with the controls (State-Trait Anxiety Inventory: mean difference, -2.80; 95% confidence interval, -4.57 to -1.03; Zung Self-Rating Anxiety Scale: mean difference, -4.80; 95% confidence interval, -7.08 to -2.52). In the subgroup analyses, the same relationship persisted when the cesarean delivery was unscheduled and when the music was selected by the patient or by the study team. The effect of music on preoperative and postoperative anxiety varied depending on which anxiety assessment tool was used. Music was also associated with decreased opioid use (mean difference, -0.87; 95% confidence interval, -1.55 to -0.19; I2=0%). CONCLUSION: In patients undergoing a cesarean delivery, music is associated with decreased intraoperative anxiety.

BACKGROUND: Due to an increase in immigration from African countries, U.S. healthcare professionals are encountering women affected by Female Genital Mutilation/Cutting (FGM/C). Little formal education exists in medical, nursing or midwifery schools. Additionally, very few studies assess attitudes and knowledge of U.S. providers to care for these women. In order to eventually offer FGM/C-affected women informed and culturally competent care, assessments of provider readiness and attitudes must guide future educational efforts. METHODS: A voluntary survey was administered to healthcare providers prior to thirteen separate education sessions on FGM/C at Philadelphia institutions. RESULTS: Of the 229 surveys distributed, 227 were returned > 50% complete. 61.2% reported encountering FGM/C at least once in the past 5 years, yet 13.7% of participants reported receiving formal training in FGM/C; 77.5% felt unprepared and 47.1% uncomfortable serving patients with FGM/C. 34.1% of participants knew the matriarchal influence on the custom. The majority of providers accurately identified the short and long-term clinical consequences of FGM/C, but 67.7% of participants denied familiarity with laws regarding FGM/C. Attitude assessment revealed beliefs that all types of FGM/C are harmful and a practice rooted in tradition. DISCUSSION: While most providers reported encountering patients with FGM/C, lack of formal training leaves them unprepared and uncomfortable serving them. Results demonstrate misunderstanding of the tradition and motives of FGM/C. Our findings support the need for expansion of provider education to provide culturally competent care for women affected by FGM/C.

OBJECTIVE: Persistent occiput posterior and occiput transverse positions are associated with adverse maternal and neonatal outcomes. The objective of this study was to assess if the use of hands-and-knees posturing increased the rate of occiput anterior position immediately after posturing during the second stage of labor or at the time of birth. DATA SOURCES: An electronic search of PubMed, EMBASE, Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials was performed from inception to September 2020. STUDY ELIGIBILITY CRITERIA: Eligibility criteria included all randomized controlled trials of singleton gestations at ≥36 weeks' gestation that were randomized to either the hands-and-knees posture group or control group. The primary outcome was a composite of occiput anterior positioning during the second stage of labor or at birth. Individual components of the composite were assessed as secondary outcomes. Additional secondary outcomes were a change to occiput anterior position immediately after the intervention, use of regional anesthesia, duration of labor, mode of delivery, third- or fourth-degree perineal laceration, neonatal birthweight, and Apgar score less than 7 at 5 minutes. METHODS: The methodological quality of all the included studies was evaluated using the Cochrane Handbook for Systematic Reviews of Interventions. A meta-analysis was performed using the random effects model of DerSimmonian and Laird to produce a summary of the treatment effects in terms of relative risk or mean difference with 95% confidence intervals. RESULTS: Of the 1079 studies screened, 5 met the inclusion criteria (n=1727 hands-and-knees posture vs n=1641 controls). When compared with the control group, patients who adopted the hands-and-knees posture had the same rate of occiput anterior positioning in the second stage of labor or at birth (81.2% vs 81.2%; relative risk, 1.03; 95% confidence interval, 0.92-1.14), as well as immediately after the intervention (34.1% vs 18.0%; relative risk, 1.60; 95% confidence interval, 0.88-2.90). On the basis of the post hoc subgroup analysis of patients with an ultrasound-diagnosed malposition before posturing, there was a higher rate of occiput anterior positioning immediately after the intervention (17.0% vs 10.3%; relative risk, 1.63; 95% confidence interval, 1.06-2.52), but this relationship did not persist at delivery. The remainder of the subgroup analyses and secondary outcomes were not significant. CONCLUSION: Adopting a hands-and-knees posture does not increase the rate of occiput anterior positioning at time of delivery.

OBJECTIVE: To describe the etiology of isolated fetal ascites and associated perinatal outcomes, and to assess the progression of isolated fetal ascites to fetal hydrops. DATA SOURCES: PubMed, Cochrane Library, Scopus, and ClinicalTrials.gov databases were searched using the following keywords: "fetus" OR "foetal" OR "fetal" OR "foetus" AND "ascites" from inception to February 2020. The search was limited to the English language. METHODS OF STUDY SELECTION: A total of 1,983 articles were identified through the search strategy. All studies containing five or more cases of isolated fetal ascites were included. TABULATION, INTEGRATION, AND RESULTS: Eleven studies, involving 315 cases of isolated fetal ascites, were eligible for inclusion in this systematic review. All included studies were evaluated using the tool for evaluating the methodologic quality of case reports and case series described by Murad et al. Data were summarized using narrative review and descriptive statistics. Two-tailed Fisher exact P values calculated from hypergeometric distribution were used to compare outcome by etiology. CIs were calculated with Clopper-Pearson exact binomial interval. The etiologies of isolated fetal ascites are genitourinary (24%), gastrointestinal (20%), viral or bacterial infections (9%), cardiac (9%), genetic disorders not otherwise categorized (8%), chylous ascites (6%), metabolic storage disorders (3%), other structural disorders (4%), other causes (4%) and idiopathic (13%). Survival is most favorable for cases of isolated fetal ascites as a result of chylous (100%), idiopathic (90%), gastrointestinal (77%) and genitourinary (77%) etiologies. Survival is least favorable for fetuses with isolated fetal ascites as a result of structural disorders (25%), cardiac etiology (32%) and metabolic storage disorders (33.3%). When pregnancy terminations were excluded, survival rates were similar between fetuses diagnosed at or after 24 weeks of gestation compared with those diagnosed at less than 24 weeks (74% vs 61%, P=.06). Progression of fetal ascites to fetal hydrops occurred in 6.6% (95% CI 3.6-9.6%) (17/259) of cases when pregnancies that were terminated were excluded. CONCLUSION: Isolated fetal ascites has a diverse etiology. Outcome is related to the etiology of isolated fetal ascites. In the majority of cases, fetal ascites does not progress to fetal hydrops.
