RESUMO
PURPOSE: We aimed to define intrauterine insemination (IUI) cycle characteristics associated with viable birth, identify thresholds below which IUI treatments are consistent with very poor prognosis and futile care, and develop a nomogram for individualized application. METHODS: This retrospective cohort study evaluated couples using fresh partner ejaculate for IUI from January 2005 to September 2017. Variables included female age, semen characteristics, and ovarian stimulation type. Using cycle-level data, we evaluated the association of these characteristics with the probability of viable birth by fitting generalized regression models for a binary outcome with a logit link function, using generalized estimating equation methodology to account for the correlation between cycles involving the same patient. RESULTS: The cohort consisted of 1117 women with 2912 IUI cycles; viable birth was achieved in 275 (9.4%) cycles. Futile care (viable birth rate < 1%) was identified for women age > 43, regardless of stimulation type or inseminate motility (IM). Very poor prognosis (viable birth rate < 5%) was identified for women using oral medications or Clomid plus gonadotropins who were (1) age < 35 with IM < 49%, (2) age 35-37 with IM < 56%, or (3) age ≥ 38, and (4) women age ≥ 38 using gonadotropins only with IM < 60%. A clinical prediction model and nomogram was developed with an optimism-corrected c-statistic of 0.611. CONCLUSIONS: The present study highlights the impact of multiple clinical factors on IUI success, identifies criteria consistent with very poor prognosis and futile care, and provides a nomogram to individualize counseling regarding the probability of a viable birth.

BACKGROUND: Uterine leiomyomas (fibroid tumors) cause considerable symptoms in 30-50% of women and are the leading cause of hysterectomy in the United States. Women with uterine fibroid tumors often seek uterine-preserving treatments, but comparative effectiveness trials are lacking. OBJECTIVE: The purpose of this study was to report treatment effectiveness and ovarian function after uterine artery embolization vs magnetic resonance imaging-guided focused ultrasound surgery from the Fibroid Interventions: Reducing Symptoms Today and Tomorrow study. STUDY DESIGN: The Fibroid Interventions: Reducing Symptoms Today and Tomorrow study, which is a randomized controlled trial of uterine artery embolization vs magnetic resonance imaging-guided focused ultrasound surgery, enrolled premenopausal women with symptomatic uterine fibroid tumors; women who declined randomization were enrolled in a parallel observational cohort. A comprehensive cohort design was used for outcomes analysis. Our target enrollment was 220 women, of which we achieved 41% (n=91) in the randomized and parallel arms of the trial. Primary outcome was reintervention for uterine fibroid tumors within 36 months. Secondary outcomes were change in serum anti-Müllerian hormone levels and standardized measures of fibroid symptoms, quality of life, pain, and sexual function. RESULTS: From 2010-2014, 83 women (mean age, 44.4 years) were treated in the comprehensive cohort design (43 for magnetic resonance imaging-guided focused ultrasound surgery [27 randomized]; 40 for uterine artery embolization [22 randomized]); baseline clinical and uterine characteristics were similar between treatment arms, except for higher fibroid load in the uterine artery embolization arm. The risk of reintervention was higher with magnetic resonance imaging-guided focused ultrasound surgery than uterine artery embolization (hazard ratio, 2.81; 95% confidence interval, 1.01-7.79). Uterine artery embolization showed a significantly greater absolute decrease in anti-Müllerian hormone levels at 24 months compared with magnetic resonance imaging-guided focused ultrasound surgery. Quality of life and pain scores improved in both arms but to a greater extent in the uterine artery embolization arm. Higher pretreatment anti-Müllerian hormone level and younger age at treatment increased the overall risk of reintervention. CONCLUSION: Our study demonstrates a lower reintervention rate and greater improvement in symptoms after uterine artery embolization, although some of the effectiveness may come through impairment of ovarian reserve. Both pretreatment anti-Müllerian hormone level and age are associated with risk of reintervention. CLINICAL TRIAL REGISTRATION NUMBER: NCT00995878, clinicaltrials.gov.

BACKGROUND: Uterine fibroids are a common problem for reproductive-aged women, yet little comparative effectiveness research is available to guide treatment choice. Uterine artery embolization and magnetic resonance imaging-guided focused ultrasound surgery are minimally invasive therapies approved by the US Food and Drug Administration for treating symptomatic uterine fibroids. The Fibroid Interventions: Reducing Symptoms Today and Tomorrow study is the first randomized controlled trial to compare these 2 fibroid treatments. OBJECTIVE: The objective of the study was to summarize treatment parameters and compare recovery trajectory and adverse events in the first 6 weeks after treatment. STUDY DESIGN: Premenopausal women with symptomatic uterine fibroids seen at 3 US academic medical centers were enrolled in the randomized controlled trial (n = 57). Women meeting identical criteria who declined randomization but agreed to study participation were enrolled in a nonrandomized parallel cohort (n = 34). The 2 treatment groups were analyzed by using a comprehensive cohort design. All women undergoing focused ultrasound and uterine artery embolization received the same postprocedure prescriptions, instructions, and symptom diaries for comparison of recovery in the first 6 weeks. Return to work and normal activities, medication use, symptoms, and adverse events were captured with postprocedure diaries. Data were analyzed using the Wilcoxon rank sum test or χ2 test. Multivariable regression was used to adjust for baseline pain levels and fibroid load when comparing opioid medication, adverse events, and recovery time between treatment groups because these factors varied at baseline between groups and could affect outcomes. Adverse events were also collected. RESULTS: Of 83 women in the comprehensive cohort design who underwent treatment, 75 completed postprocedure diaries. Focused ultrasound surgery was a longer procedure than embolization (mean [SD], 405 [146] vs 139 [44] min; P <.001). Of women undergoing focused ultrasound (n = 43), 23 (53%) underwent 2 treatment days. Immediate self-rated postprocedure pain was higher after uterine artery embolization than focused ultrasound (median [interquartile range], 5 [1-7] vs 1 [1-4]; P = .002). Compared with those having focused ultrasound (n = 39), women undergoing embolization (n = 36) were more likely to use outpatient opioid (75% vs 21%; P < .001) and nonsteroidal antiinflammatory medications (97% vs 67%; P < .001) and to have a longer median (interquartile range) recovery time (days off work, 8 [6-14] vs 4 [2-7]; P < .001; days until return to normal, 15 [10-29] vs 10 [10-15]; P = .02). There were no significant differences in the incidence or severity of adverse events between treatment arms; 86% of adverse events (42 of 49) required only observation or nominal treatment, and no events caused permanent sequelae or death. After adjustment for baseline pain and uterine fibroid load, uterine artery embolization was still significantly associated with higher opioid use and longer time to return to work and normal activities (P < .001 for each). Results were similar when restricted to the randomized controlled trial. CONCLUSION: Women undergoing uterine artery embolization have longer recovery times and use more prescription medications, but women undergoing focused ultrasound have longer treatment times. These findings were independent of baseline pain levels and fibroid load.

BACKGROUND: Past research has found that family involvement in psychosis treatment leads to better patient outcomes. Thus, caregiver communication skills training can be a viable approach to reducing caregiver stress and increasing self-efficacy and communication. AIM: The purpose of this qualitative study was to describe family caregivers' perceptions of changes in themselves and their family member with psychosis following their participation in Motivational Interviewing in Loved Ones (MILO), a brief four to five-hour psychoeducational intervention for caregivers. METHODS: Sixty-three participants in the MILO trials provided written qualitative responses to the prompt, "Since learning the ideas and techniques in this course, what is the most significant change you noticed in yourself, your family, or your relationships?" Responses were collected immediately following MILO participation and 12 weeks later. Qualitative themes were identified through an iterative consensus process. RESULTS: Most participants reported positive changes in multiple domains of their lives. Major themes included: (1) Changes in Self, (2) Changes in Relationships, (3) Changes in Mindset, (4) Use of MILO Skills, and (5) Challenges. CONCLUSION: Qualitative results support and add context to the previously reported quantitative results from this study. MILO is a promising family intervention that positively influenced family environment and communication in pilot trials. Adaptations of MILO for families outside of a highly educated North American context should be considered.

This is the case of a 60-year-old man with no known medical history who presented with progressively worsening lumbar pain and was found to have idiopathic dorsal epidural lipomatosis. The patient's condition improved significantly with pain management. Therefore, no surgical intervention was warranted at the time, but the patient was advised to keep close follow-up as an outpatient. Being familiar with this potential cause of lumbar pain is vital, as it can lead to severe morbidity if left unrecognized.
RESUMO
This retrospective, cross-sectional study was conducted in four community hospitals in Los Angeles County, California. The assumption of this study was, coronavirus disease-19 (COVID-19) contributed to the increase in healthcare workers compliance with infection prevention measures. IP initiatives fostered among HCWs have increased awareness of effective hand washing, cleaning equipment after use and appropriate personal protective equipment use which has subsequently decreased healthcare acquired infections with multidrug-resistant organisms.

BACKGROUND: Preventing respiratory infectious disease exposures is a performance improvement project to reduce the incidence of occupational health exposures among health care workers. This project encouraged registered nurses to quickly identify and isolate potentially infectious patients in the emergency room, to prevent exposures to airborne and droplet transmitted communicable diseases, including meningitis, tuberculosis, and measles. METHODS: This pre- and postintervention model implemented a quasi-experimental designed project in the emergency room (ER). The Centers for Disease Control's empiric transmission-based isolation precautions were implemented to prevent occupational health exposures. Eighty registered nurses (RN's) received education on the new intervention. The assumption of this project was, the new process will decrease occupational health exposures. RESULTS: Eight ER RNs reported an occupational health exposure, preintervention in quarter 2 of 2019, compared to zero occupational health exposures, postintervention in quarter 3 of 2019. A χ² independence test was used to determine if the categorical variables of the capstone intervention and disease exposure were related in the same RN population. An association between the capstone intervention and disease exposure was observed, X2 (1)â¯=â¯8.421, Pâ¯=â¯.004, indicating the result is statistically significant. CONCLUSIONS: The preventing respiratory infectious disease exposures project effectively reduced occupational health exposures to airborne and droplet transmitted diseases in the emergency room by 100%. These results should encourage Infection Preventionists to adapt the Centers for Disease Control's empiric transmission isolation precautions in their emergency rooms and urgent cares to prevent airborne and droplet transmitted disease exposures.

Interventional radiology is a procedural specialty that performs minimally invasive operations under image guidance. Currently, there are inadequate ergonomic protocols for work-related musculoskeletal disorder (WMSD) prevention in interventional radiology (IR), and there is a paucity of information discerning gender differences in WMSDs. This article reviews current literature that addresses WMSDs in female physicians practicing interventional and fluoroscopic procedures, including interventional radiology, interventional cardiology, electrophysiology, vascular surgery, orthopedic surgery, neurosurgery, and gastroenterology. We searched PubMed and EBSCOhost databases for ergonomic studies that reported female physician WMSDs in the specialties listed above. After a thorough evaluation for inclusion based on eligibility criteria, 11 studies were included. From this search, there was poor female representation, averaging 25.7% of respondents. Several characteristics identified across the studies were that women were generally shorter, wore smaller glove sizes, and were younger than their male colleagues. Seventy-two percent of female proceduralists reported WMSDs versus 46.6% of their male colleagues. Additionally, women may experience more upper extremity pain than lumbar pain, which men commonly reported. Potential contributing factors to WMSDs are the size and design of procedural tools and the possible predisposition of female physicians to experience upper extremity WMSDs while performing the same operations as men. As more women enter medicine and pursue careers in procedural fields like interventional radiology, it is essential to address these discrepancies and develop ergonomically sound solutions for women.
RESUMO
Hereditary multiple exostoses (HME) are an autosomal dominant skeletal disorder characterized by the development of multiple benign osteochondromas (exostoses) that frequently involve long bones of the body. Less commonly, the ribs are a site of involvement, and long-term friction between an exostosis and pleura can produce a hemothorax or pneumothorax. The purpose of this study is to provide a comprehensive review of existing literature on pneumothorax or hemothorax secondary to costal exostosis in HME patients. We reviewed the databases of PubMed and Embase and included data as current as of February 15, 2021. All case reports included cases of hemothorax or pneumothorax in patients with a known personal or family history of HME. After evaluation for inclusion based on eligibility criteria, 18 cases were included. The average age at presentation was 11.7 years (range: 3-32), and most patients were male (83%). Hemothoraces occurred in 15 cases, while pneumothoraces occurred in three cases. All cases were evaluated using chest X-ray and CT scan, and the majority of the cases were treated with surgical resection of the exostosis, either with video-assisted thoracoscopic surgery (VATS; 61%) or thoracotomy (22%). Outcomes were successful with no cases of recurrence after surgical intervention. Although rare, costal exostosis should be considered as a differential in patients presenting with pneumothorax or hemothorax and past medical history or physical exam findings suggestive of HME. Immediate evaluation and surgical intervention to resect costal exostosis are essential to reduce the risk of recurrent life-threatening injury.
RESUMO
Predicting release from degradable hydrogels is challenging but highly valuable in a multitude of applications such as drug delivery and tissue engineering. In this study, we developed a simple mathematical and computational model that accounts for time-varying diffusivity and geometry to predict solute release profiles from degradable hydrogels. Our approach was to use time snapshots of diffusivity and hydrogel geometry data measured experimentally as inputs to a computational model which predicts release profile. We used two model proteins of varying molecular weights: bovine serum albumin (BSA; 66 kDa) and immunoglobulin G (IgG; 150 kDa). We used fluorescence correlation spectroscopy (FCS) to determine protein diffusivity as a function of hydrogel degradation. We tracked changes in gel geometry over the same time period. Curve fits to the diffusivity and geometry data were used as inputs to the computational model to predict the protein release profiles from the degradable hydrogels. We validated the model using conventional bulk release experiments. Because we approached the hydrogel as a black box, the model is particularly valuable for hydrogel systems whose degradation mechanisms are not known or cannot be accurately modeled.
RESUMO
BACKGROUND: Fertility preservation enables patients undergoing gonadotoxic therapies to retain the potential for biological children and now has broader implications in the care of transgender individuals. Multiple medical societies recommend counseling on fertility preservation before initiating therapy for gender dysphoria; however, outcome data pre- and posttreatment are limited in feminizing transgender adolescents and young adults. METHODS: The University of Pittsburgh Institutional Research Board approved this study. Data were collected retrospectively on transgender patients seeking fertility preservation between 2015 and 2018, including age at initial consultation and semen analysis parameters. RESULTS: Eleven feminizing transgender patients accepted a referral for fertility preservation during this time; consultation occurred at median age 19 (range 16-24 years). Ten patients attempted and completed at least 1 semen collection. Eight patients cryopreserved semen before initiating treatment. Of those patients, all exhibited low morphology with otherwise normal median semen analysis parameters. In 1 patient who discontinued leuprolide acetate to attempt fertility preservation, transient azoospermia of 5 months' duration was demonstrated with subsequent recovery of spermatogenesis. In a patient who had previously been treated with spironolactone and estradiol, semen analysis revealed persistent azoospermia for the 4 months leading up to orchiectomy after discontinuation of both medications. CONCLUSIONS: Semen cryopreservation is a viable method of fertility preservation in adolescent and young adult transgender individuals and can be considered in patients who have already initiated therapy for gender dysphoria. Further research is needed to determine the optimal length of time these therapies should be discontinued to facilitate successful semen cryopreservation.

Polycystic ovary syndrome (PCOS) typically manifests with a combination of menstrual dysfunction and evidence of hyperandrogenism in the adolescent population. No single cause has been identified; however, evidence suggests a complex interplay between genetic and environmental factors. Polycystic ovary syndrome presents a particular diagnostic challenge in adolescents as normal pubertal changes can present with a similar phenotype. Management of PCOS in the adolescent population should focus on a multi-modal approach with lifestyle modification and pharmacologic treatment to address bothersome symptoms. This chapter outlines the pathogenesis of PCOS, including the effects of obesity, insulin resistance, genetic, and environmental factors. The evolution of the diagnostic criteria of PCOS as well as specific challenges of diagnosis in the adolescent population are reviewed. Finally, evidence for lifestyle modification and pharmacologic treatments are discussed.
