RESUMO

BACKGROUND: In 2016, the US Food and Drug Administration amended existing regulations to increase access to donated embryos for reproductive use. Current information regarding the characteristics and outcomes of embryo donation cycles could benefit patients and providers during counseling and decision making. OBJECTIVE: This study aimed to examine the trends in the utilization of embryo donation, pregnancy rates, and live birth rates per transfer between 2004 and 2019 and to describe the recipients of donated embryos and outcomes of frozen donated embryo transfer cycles during the most recent time period, that is, 2016 to 2019. STUDY DESIGN: We conducted a retrospective, population-based cohort study of frozen donated embryo transfer cycles in United States fertility clinics reporting to the National Assisted Reproductive Technology Surveillance System during 2004 to 2019. The trends in the annual number and proportion of frozen donated embryo transfers, pregnancy rates, and live birth rates from 2004 to 2019 were described. During 2016 to 2019, the rates of cycle cancellation, pregnancy, miscarriage, live birth, singleton birth, and good perinatal outcome (delivery ≥37 weeks, birthweight ≥2500 g) of frozen donated embryo transfers were also calculated. Transfer and pregnancy outcomes stratified by oocyte source age at the time of oocyte retrieval were also described. RESULTS: From 2004 to 2019, there were 21,060 frozen donated embryo transfers in the United States, resulting in 8457 live births. During this period, the annual number and proportion of frozen donated embryo transfers with respect to all transfers increased, as did the pregnancy rate and live birth rate. Among all initiated cycles during 2016 to 2019, the cancellation rate was 8.2%. Among 8773 transfers with known outcomes, 4685 (53.4%) resulted in pregnancy and 3820 (43.5%) in live birth. Among all pregnancies, 814 (17.4%) resulted in miscarriage. Among all live births, 3223 (84.4%) delivered a singleton, of which 2474 (76.8%) had a good perinatal outcome. The clinical pregnancy rate and live birth rate per frozen donated embryo transfer decreased with increasing age of oocyte source. CONCLUSION: The outcomes of embryo donation cycles reported in this national cohort may aid patients and providers when considering the use of donated embryos.

RESUMO

BACKGROUND: Insurance coverage for fertility services may reduce the financial burden of high-cost fertility care such as assisted reproductive technology and improve its utilization. Patients who exit care after failing to reach their reproductive goals report higher rates of mental health problems and a lower sense of well-being. It is important to understand the relationship between state-mandated insurance coverage for fertility services and assisted reproductive technology care discontinuation. OBJECTIVE: This study aimed to assess whether state-mandated insurance coverage for fertility services is associated with lower rates of care discontinuation after an initial assisted reproductive technology cycle that did not result in a live birth. STUDY DESIGN: This is a retrospective, population-based cohort study using data from United States fertility clinics reporting to the National Assisted Reproductive Technology Surveillance System during 2016 and 2018. Patients who began their first autologous assisted reproductive technology cycle during 2016 and 2017 and did not have a live birth were included. We describe the rate of assisted reproductive technology care discontinuation (no additional cycle within 12 months of the previous cycle's date of failure). Multivariable analyses were conducted to evaluate factors independently associated with care discontinuation, including the scope of fertility services included in state coverage mandate at assisted reproductive technology cycle initiation that were as follows: comprehensive (≥3 assisted reproductive technology cycles), limited (1, 2, or an unspecified number of assisted reproductive technology cycles), mandate not including assisted reproductive technology, and no mandate. RESULTS: Among 91,324 patients who underwent their first autologous assisted reproductive technology cycle that did not result in live birth, 24,072 (26.4%) discontinued care. Compared with patients who lived in states with mandates for comprehensive assisted reproductive technology coverage, those in states with mandates for fertility services coverage that did not include assisted reproductive technology or states with no mandate were 46% (adjusted relative risk, 1.46; 95% confidence interval, 1.31-1.63) and 26% (adjusted relative risk, 1.26; 95% confidence interval, 1.15-1.39) more likely to discontinue care, respectively, after controlling for patient and cycle characteristics. Increasing patient age, distance from clinic ≥50 miles, previous live birth, fewer oocytes retrieved, and not having embryos cryopreserved were also associated with higher rates of discontinuation. Non-Hispanic Black, non-Hispanic Asian, and Hispanic patients had higher rates of care discontinuation than non-Hispanic White patients regardless of the existence or scope of state-mandated assisted reproductive technology coverage. CONCLUSION: Comprehensive state-mandated insurance coverage for assisted reproductive technology is associated with lower rates of assisted reproductive technology care discontinuation.

RESUMO

PURPOSE: Emerging data suggests improved obstetric outcomes with frozen embryo transfer (FET) in an ovulatory or natural cycle (NC-FETs), as compared to programmed endometrial preparation. The objective of this study is to better understand practice patterns and provider attitudes regarding the use of NC-FETs in the United States (U.S.). METHODS: In this cross-sectional study, an anonymous 22-question survey was emailed to 441 U.S. Assisted Reproductive Technology (ART) clinics to assess the utilization of NC endometrial preparation for FET, protocols used, restrictions to offering NC-FET, and providers' perspectives on advantages and disadvantages of NC-FET. Descriptive statistics were used to analyze survey responses. RESULT(S): The survey response rate was 49% (216/441). Seventeen percent of responding clinics did not offer NC-FET. Of the clinics that did not offer NC-FET, 65% had only 1-2 physicians in their practice. Common reasons for not offering NC-FET included "lack of timing predictability for transfer" (81%) and "increased burden on staff/laboratory personnel on holidays and weekends" (54%). Of clinics offering NC-FET, 76% reported < 25% of cycles used the NC for endometrial preparation. Over half (52%) of clinics that offered NC-FET reported having eligibility restrictions for NC-FET. Reported benefits of NC-FET were "patient satisfaction" (18%), "decreased cost of medications" (18%), and "avoidance of intramuscular progesterone" (17%). The attitude towards NC-FET in their clinics was reported as positive by 65% of respondents. CONCLUSION: NC-FETs are offered by most U.S. ART clinics but are used only in the minority of FET cycles for endometrial preparation, and use is often restricted.

RESUMO

Ovarian dermoid cysts, also called mature cystic teratomas (MCTs), account for 69% of ovarian germ cell tumors in young women. The tumors are formed by tissues derived from three germ layers, and sebaceous materials are most commonly seen. The origin of MCTs is widely considered to be the germ cell origin, which completes meiosis I. The clinical symptoms vary widely, but 20% of tumors could be asymptomatic. The diagnosis of MCTs is usually made without difficulty by ultrasound and confirmed by histopathology post-operatively. The imaging findings have a high diagnostic value. The typical characteristics present in the sonographic images, including a dermoid plug or Rokitansky nodule, are considered strong evidence for a teratoma. Although the malignant transformation of MCTs is rare, it can occur in some cases, especially in women of advanced age. The treatment of MCTs depends on the risk of malignancy, the age of the patient, and the patient's fertility reserve requirement. In this article, we review the epidemiology, clinical symptoms, diagnosis criteria, cellular origin, and treatment of mature cystic teratomas.

RESUMO

Indigenous people experience a higher rate of intimate partner violence (IPV) than other racial/ethnic groups; however, limited research examines IPV among this population. In collaboration with a tribe in the western United States, this study surveyed a sample of indigenous people (N = 27) to learn about their experiences with victimization. Results show that respondents experienced high amounts of recent relationship and lifetime victimization, mostly consistent with previous literature. Additional issues and challenges emerged from the data, such as low reporting rates and service accessibility. These findings are contextualized within prior IPV literature, and we offer recommendations for future research.

RESUMO

BACKGROUND: Intimate partner violence (IPV) is a significant public health issue, and when experienced during pregnancy, IPV substantially harms maternal health. Still, limited research has examined how IPV may influence prenatal oral health and dental care utilization. This study investigates the relationship between IPV during pregnancy and women's oral health experiences. DATA: Data are from 31 states from 2016-2019 in the United States that participated in the Pregnancy Risk Assessment Monitoring System (N = 85,289)-a population-based surveillance system of live births conducted annually by the Centers for Disease Control and Prevention and state health departments. Multivariable logistic regression analyses were used to examine the association between physical IPV during pregnancy (measured by being pushed, hit, slapped, kicked, choked, or physically hurt any other way by a current or ex-husband/partner) and various oral health experiences. FINDINGS: Women who experienced prenatal physical IPV reported worse oral health experiences during pregnancy, including being more likely to report not knowing it was important to care for their teeth, not talking about dental health with a provider, needing to see a dentist for a problem, going to see a dentist for a problem, as well as having more unmet dental care needs. CONCLUSIONS: Together, these findings indicate that women who experience physical IPV during pregnancy have lower knowledge of prenatal oral health care, more oral health problems, and greater unmet dental care needs. Given the risk of IPV and oral health problems for maternal and infant health, the study findings point to greater attention toward the oral health needs of IPV-exposed pregnant women.

RESUMO

The use of frozen embryo transfer in assisted reproductive technology (ART) has steadily increased since development in the early 1980's. While there are many benefits to delayed frozen embryo transfer, certain adverse perinatal outcomes are noted to be more common in these transfers when compared to fresh transfers, specifically hypertensive disorders of pregnancy. Frozen embryo transfers require coordination between the embryo's developmental stage and the endometrial environment and can occur in either ovulatory or programmed cycles. Though there is no consensus on the ideal method of endometrial preparation prior to frozen embryo transfer, emerging data suggests differences in maternal and neonatal outcomes, specifically increased rates of hypertensive disorders of pregnancy in programmed cycles. Other reported differences include an increased risk of cesarean delivery, placenta accreta, postpartum hemorrhage, low birthweight, preterm birth, post term delivery, macrosomia, large for gestational age, and premature rupture of membranes in programmed cycles. The mechanism by which these differences exist could reflect inherent differences in groups selected for each type of endometrial preparation, the role of super physiologic hormone environments in programmed cycles, or the unique contributions of the corpus luteum in ovulatory cycles that are not present in programmed cycles. Given that existing studies are largely retrospective and have several key limitations, further investigation is needed. Confirmation of these findings has implications for current practice patterns and could enhance understanding of the mechanisms behind important adverse perinatal outcomes in those pursuing assisted reproduction.

RESUMO

OBJECTIVE: Anorexia nervosa (AN) with compulsive exercise is associated with poor treatment outcomes. This study sought to understand the attitudes of adolescents with AN from various stages of treatment, toward physical activity research practices and physical activity as a component of treatment. METHOD: Seventeen adolescents 12-18 years old (15 female) with AN (10 with acknowledged history of compulsive exercise) were recruited from a Canadian Tertiary Care Hospital's Eating Disorder Program. Six inpatients, 5-day program patients, and six outpatients treated by either the inpatient and/or day treatment program in the past 2 years completed individual, semi-structured interviews that were audio-recorded and transcribed. Results were analyzed deductively using qualitative techniques. RESULTS: Participants recognized both benefits (psychological, sociological, and physiological) and risks (trigger negative thoughts, increase competitive behavior) of implementing physical activity into acute AN treatment. Patient characteristics, such as stage of treatment and exercise history, had an impact on participants' perceptions toward physical activity in AN. Participants suggested that the ideal physical activity program would be focused on fun, individualized and progressively integrated, group-based, and directly supported by staff. Although the majority of participants stated that they would wear an activity monitor for research purposes, concerns were voiced regarding compliance and the potential impact on eating disorder symptomatology. DISCUSSION: Participants overwhelmingly supported the careful implementation of structured physical activity and physical activity psychoeducation into the acute treatment of adolescents with AN. This study allows for the inclusion of patient voices in the conversation surrounding the role of physical activity in AN treatment.

RESUMO

BACKGROUND: Various manoeuvres such as McRoberts position, suprapubic pressure, rotational methods, posterior arm extraction and all-four position (HELPERR) have been proposed for relieving shoulder dystocia with variable success. Posterior axillary sling method using a rubber catheter was proposed in 2009 but has not been widely used. We modified this method using ribbon gauzes and a long right-angle forceps and report a successful case. CASE PRESENTATION: A 44 years old parity one Chinese woman with a history of a caesarean delivery and poorly controlled type 2 diabetes mellitus was admitted to the Accident and Emergency Department for advanced stage of labour at term. Upon arrival, intrauterine fetal demise was diagnosed with severe asynclitism causing obstruction at the perineum. Episiotomy resulted in birth of the fetal head. The fetal posterior right shoulder, however, remained very high up in the pelvis and HELPERR methods failed to extract the shoulders. We then tied two long ribbon gauzes together, and guided its knot to the anterior aspect of the posterior axilla. By using a long right-angle forceps (24 cm long) to grasp the knot on the posterior side of the axilla and pulling it through, a sling was formed. Traction was then applied through the sling to simultaneously pull and rotate the posterior shoulder. A stillbirth of 3488 g was finally extracted. CONCLUSIONS: We modified the sling method by using two ribbon gauzes, tied together and a right-angle forceps with several advantages. Compared to a rubber catheter, ribbon gauze with a knot can be easily held between the fingers for easy guidance past the fetal axilla. It is also thin, non-elastic and stiff enough to ensure a good grip for traction. The long and slim design of the right-angle forceps makes it easy to pass through a narrow space and reach the axilla high up in the pelvis. We emphasize simultaneous traction and rotation, so that the shoulders are delivered through the wider oblique pelvic outlet dimension.

RESUMO

BACKGROUND/OBJECTIVE: Catheter-associated urinary tract infections (CAUTIs) account for 25% of all hospital-acquired infections. Neuro-critically ill patients are at 2-5 times greater risk of developing CAUTI because of increased use of indwelling urinary catheters due to neurogenic urinary retention. Despite the heightened risk of CAUTI occurrence for the neuro-critically ill, there is little data on specific characteristics of CAUTIs and risk factors among this population. The aim of this study was to identify characteristics and risk factors associated with CAUTI development in the neuro-critical patient population. METHODS: In this retrospective single-center case-control study in a tertiary care dedicated 30-bed neuroICU, approximately 3 controls (exact ratio-3.2) were randomly selected for each CAUTI case between January 1st, 2016 and December 31st, 2018. Demographic, clinical and laboratory data were collected, including prospectively collected data pertaining to urinary and bowel function. Descriptive and multivariate logistic regression analysis was conducted to identify common patient characteristics, CAUTI risk factors and duration from catheterization to developing a CAUTI (Time-to-CAUTI). RESULTS: Of 3045 admissions during the study period, 1045 (34.30%) had a urinary catheter at some point during their admission. Of those, 45 developed a CAUTI, yielding a CAUTI incidence rate of 1.50%, corresponding to 4.49 infections/1000 catheter days. On average, CAUTI patients were older as compared to controls (66.44 years of age vs 58.09 years; p < 0.0001). In addition to old age, other risk factors included female gender (75.60% female vs 24.20% males in case group, p < 0.0001), increased neuroICU length of stay (18.31 in cases vs. 8.05 days in controls, p = 0.0001) and stool incontinence (OR = 3.73, p = 0.0146). CAUTI patients more often carried a primary diagnosis of SAH, and comorbidities of hypertension (HTN), vasospasm and diabetes. Time-to-CAUTI was 6 days on average, with an earlier peak for patients requiring two or more catheter placements. Presence of stool incontinence was significantly associated with CAUTI occurrence. CONCLUSION: Stool incontinence, older age, female sex, longer neuroICU LOS and presence of comorbidities such as HTN and diabetes were associated with CAUTI development in the neuro-critically ill population. Average Time-to-CAUTI after catheter placement was 6 days with earlier occurrence if more frequent catheterizations. Colonization of urinary catheters without infection might contribute to CAUTI diagnosis. Prospective research is needed to determine impact of prevention protocols incorporating these factors.

RESUMO

ABSTRACTBackground:Neuropsychiatric symptoms (NPI) of dementia are important determinants of caregiver burden, while caregiver coping styles and competences can relieve burden. Caregivers differ in coping with the demands made on them and in experienced burden. What changes in caregivers explain recovery from burden, and which caregiver characteristics predict recovery from burden over time, and does treatment make a difference? METHODS: This study into recovery from burden was a secondary analysis of data collected in a formerly conducted randomized controlled trial (RCT) on the integrated reactivation and rehabilitation (IRR) programme in a psychiatric-skilled nursing home, compared to usual care (UC; i.e. day care, assisted living arrangements, and nursing home wards). For this secondary analysis, longitudinal data on persons with dementia and caregivers were used from baseline (T1), end of treatment (T2), and at nine months (T3). RESULTS: Caregivers with an improved sense of competence (SCS) who care for persons with dementia with a decreased severity of NPI have the highest chance of recovering from burden (CSI). Caregivers with a tendency to feel involved with others and sympathize with others (affiliation, ICL-R) have a slightly lower probability of improvement with respect to their sense of competence in the short term. The number of improved caregivers was higher in IRR than UC. CONCLUSION: Recovery depends on both an improved sense of competence and a decreased severity of NPI. Combined interventions that address both NPI and focus on enhancing caregiver's sense of competence have added value when it comes to decreasing caregiver burden.

RESUMO

OBJECTIVE: Bystander cardiopulmonary resuscitation (CPR) after out-of-hospital cardiac arrest (OHCA) improves survival and neurological outcomes. Nonetheless, many OHCA patients do not receive bystander CPR during a witnessed arrest. Our aim was to identify potential barriers to bystander CPR. METHODS: Participants at CPR training events conducted in the USA between February and May 2018 answered a 14-question survey prior to training. Respondents were asked about their overall comfort level performing CPR, and about potential concerns specific to performing CPR on a middle-aged female, a geriatric male, and male and female adolescent patients. Open-ended responses were analysed qualitatively by categorising responses into themes. RESULTS: Of the 677 participants, 582 (86.0%) completed the survey, with 509 (88.1%) between 18 and 29 years of age, 341 (58.6%) without prior CPR training and 556 (96.0%) without prior CPR experience. Across all four scenarios of patients in cardiac arrest, less than 65% of respondents reported that they would be 'Extremely Likely' (20.6%-29.1%) or 'Moderately Likely' (26.9%-34.8%) to initiate CPR. The leading concerns were 'causing injury to patient' for geriatric (n=193, 63.1%), female (n=51, 20.5%) and adolescent (n=148, 50.9%) patients. Lack of appropriate skills was the second leading concern when the victim was a geriatric (n=41, 13.4%) or adolescent (n=68, 23.4%) patient, whereas for female patients, 35 (14.1%) were concerned about exposing the patient or the patient's breasts interfering with performance of CPR and 15 (6.0%) were concerned about being accused of sexual assault. Significant differences were observed in race, ethnicity and age regarding the likelihood of starting to perform CPR on female and adolescent patients. CONCLUSIONS: Participants at CPR training events have multiple concerns and fears related to performing bystander CPR. Causing additional harm and lack of skills were among the leading reservations reported. These findings should be considered for improved CPR training and public education.

RESUMO

Xenbase (http://www.xenbase.org), the Xenopus frog model organism database, integrates a wide variety of data from this biomedical model genus. Two closely related species are represented: the allotetraploid Xenopus laevis that is widely used for microinjection and tissue explant-based protocols, and the diploid Xenopus tropicalis which is used for genetics and gene targeting. The two species are extremely similar and protocols, reagents and results from each species are often interchangeable. Xenbase imports, indexes, curates and manages data from both species; all of which are mapped via unique IDs and can be queried in either a species-specific or species agnostic manner. All our services have now migrated to a private cloud to achieve better performance and reliability. We have added new content, including providing full support for morpholino reagents, used to inhibit mRNA translation or splicing and binding to regulatory microRNAs. New genomes assembled by the JGI for both species and are displayed in Gbrowse and are also available for searches using BLAST. Researchers can easily navigate from genome content to gene page reports, literature, experimental reagents and many other features using hyperlinks. Xenbase has also greatly expanded image content for figures published in papers describing Xenopus research via PubMedCentral.

RESUMO

OBJECTIVES: Caring for a patient with dementia is a real challenge and can have considerable psychological consequences in the long run. Many caregivers, mostly relatives, feel highly burdened. To develop effective caregiver support to prevent caregivers from getting overburdened, insight is needed into the determinants of burden. The objective of this study is to explore which patient and caregiver characteristics determine the different kinds of caregiver burden over time, both in the short and in the long run. METHOD: The study was longitudinal. Data on patients and caregivers, general burden and emotional distress were collected at three times: at baseline, at the end of treatment and at nine months. The study was conducted in a psychiatric skilled nursing home with a unit for integrative reactivation and rehabilitation (IRR) and at different sites of home-/day care, assisted living arrangements and nursing home wards (usual care). RESULTS: General burden is shown to be determined by severity of patient's neuropsychiatric symptoms, caregiver's sense of competence, health-related quality of life. Emotional distress is determined by severity of patient's neuropsychiatric symptoms, caregiver's sense of competence, high affiliation and patient gender. CONCLUSION: In preventing or treating caregiver burden, professional interventions need to aim specifically at diminishing the neuropsychiatric symptoms in dementia patients and improving the sense of competence in caregivers.

RESUMO

The gills of euryhaline fish are the ultimate ionoregulatory tissue, achieving ion homeostasis despite rapid and significant changes in external salinity. Cellular handling of sodium is not only critical for salt and water balance but is also directly linked to other essential functions such as acid-base homeostasis and nitrogen excretion. However, although measurement of intracellular sodium ([Na(+)]i) is important for an understanding of gill transport function, it is challenging and subject to methodological artifacts. Using gill filaments from a model euryhaline fish, inanga (Galaxias maculatus), the suitability of the fluorescent dye CoroNa Green as a probe for measuring [Na(+)]i in intact ionocytes was confirmed via confocal microscopy. Cell viability was verified, optimal dye loading parameters were determined, and the dye-ion dissociation constant was measured. Application of the technique to freshwater- and 100% seawater-acclimated inanga showed salinity-dependent changes in branchial [Na(+)]i, whereas no significant differences in branchial [Na(+)]i were determined in 50% seawater-acclimated fish. This technique facilitates the examination of real-time changes in gill [Na(+)]i in response to environmental factors and may offer significant insight into key homeostatic functions associated with the fish gill and the principles of sodium ion transport in other tissues and organisms.

RESUMO

BACKGROUND: During the course of evaluation for primary hyperaldosteronism, cross-sectional imaging is obtained in efforts to identify patients with an aldosterone producing adenoma (APA). A subset of these patients will have a synchronous, contralateral adrenal abnormality. Adrenal vein sampling (AVS) further guides clinical decision making by identifying unilateral (APA) versus bilateral hypersecretion. In the subset of patients with contralateral adrenal abnormalities, it is unclear how this affects the durability of an adrenalectomy for APA. This study characterizes this group of patients to assess the efficacy of surgical intervention. METHODS: A retrospective review of patients undergoing adrenalectomy for APA based on AVS at a university practice. Preoperative and postoperative patient characteristics, laboratory evaluations, imaging results, and final pathology were noted. RESULTS: From 2000 to 2011, 103 patients with APA underwent unilateral adrenalectomy. Eighteen patients (17%) had discordant results between AVS and imaging. Most of these patients were male (78%), and the mean age was 57 ± 13 y. Median duration of follow-up was 3.5 y [1 y, 6 y]. All patients with initial hypokalemia were rendered normokalemic after the operation. Four patients increased their antihypertensive regimen during the follow-up period. These patients all had nodular hyperplasia on final pathology. CONCLUSIONS: In patients with bilateral adrenal abnormalities who have undergone unilateral adrenalectomy for primary hyperaldosteronism, patients with clear APAs on final pathology appear to have durable outcomes after resection. Conversely, nodular hyperplasia on final pathology may be a risk factor for ongoing aldosterone hypersecretion. An algorithm for biochemical surveillance in this subset of patients should be considered.
