RESUMO
HIV post-exposure prophylaxis (PEP) can reduce the risk of acquiring HIV infection following sexual assault. However, only about half of people offered HIV PEP will initiate the medication. Factors associated with patient readiness for HIV PEP following sexual assault have been attributed to structural and clinical barriers. This study utilized the Theory of Reasoned Action and Planned Behavior to better understand how personal factors, cognitive factors, mental health, barriers and facilitators that could influence a patient's decision to start HIV PEP post sexual assault. A web-based cross sectional survey was conducted from October 2017 to January 2020 and a total of 228 responses were included from participants that had experienced sexual assault in the previous 3 months. Using linear regression modeling fear of HIV, post-traumatic stress symptoms, validating social responses to disclosure, and having someone else pay for HIV PEP were all associated with feeling better prepared for HIV PEP decision making. Results indicate that structural, social, and individual factors impact patient decision making. These findings highlight opportunities for health systems and providers to improve HIV education and the importance of initiating HIV PEP following sexual assault.
RESUMO
Microbial cell-free DNA (mcfDNA) sequencing is a promising tool to identify infectious pathogens when traditional methods fail to identify the causative agent. We performed a retrospective observational cohort study to evaluate clinical outcomes among pediatric and adult patients who underwent mcfDNA testing. 127 mcfDNA tests were reviewed from 112 patients. Baseline characteristics included 61 (54.5 %) adults, 52 (40.9 %) tests were from female patients, and 67 (52.8 %) tests were obtained from patients designated as immunocompromised. Of all tests obtained, 59 (46.4 %) were deemed clinically relevant. 41 (32.3 %) of tests also led to a change in antimicrobial management for the corresponding patient. No statistically significant association was ascertained between patient-specific factors and clinically relevant test results. Testing in certain clinical scenarios or high-risk settings may be useful, however further studies are needed to assess the cost-benefit of this approach.

Race as a variable in a predictive model for a successful vaginal birth after cesarean delivery has been challenged as contributing to health inequity. In May 2022, the National Institute of Child Health and Development released a modified calculator that removed race as a variable. The aim of this study was to externally validate the revised calculator amongst a cohort at our institution. We reviewed all patients who underwent a trial of labor after cesarean delivery in 2018-2020 at a tertiary academic medical center and calculated the predicted probability of successful vaginal birth after cesarean delivery for each patient using both original and revised classification calculators and compared these to observed birth outcomes. The area under the receiver operating characteristic curve was calculated for each model. From the cohort of 225 patients that fit inclusion criteria, 37% (n=83) identified as African-American or Hispanic. The vaginal birth after cesarean delivery success rate was 75% for the entire population, and 76% among African-American and/or Hispanic patients. The area under the receiver operating characteristic curve of the original calculator was 0.71, compared to 0.74 for the new calculator. For African-American and/or Hispanic patients, the average predicted success rates between the models rose from 60 to 69%. Our review confirmed that African-American and Hispanic patients were calculated to have a lower prediction score for a successful vaginal birth after cesarean delivery based on the original calculator as compared to the revised calculator. Our results also suggest that race/ethnicity did not significantly contribute to classification ability of the calculator in our patient population.
RESUMO
BACKGROUND: As COVID-19 has emerged as a pandemic virus, multiple reports have surfaced to describe skin lesions that occur either associated with the virus or due to treatment. OBJECTIVE: To compare patient demographics, treatments, and outcomes in COVID-19 symptomatic patients who developed skin lesions (COVID-19 or hospital-acquired pressure ulcer/injury [HAPU/I]) during the first year of the pandemic. METHODS: A retrospective chart review was conducted on COVID-positive symptomatic patients admitted from March 1, 2020, through March 1, 2021. The authors analyzed the difference in patient demographics, patient skin tones, treatments, hospital length of stay (LOS), intensive care unit (ICU) LOS, death, and discharge disposition for those with COVID-19 lesions compared to those who developed HAPU/Is. RESULTS: Of those who developed lesions, 2.3% developed COVID-19 lesions and 7.2% developed HAPU/Is. Patients with COVID-19 lesions were more likely to be male (64%), younger (median age 60), and had a higher BMI (30) than patients with no wounds and patients with HAPU/I. CONCLUSION: This study advances the knowledge of the patient demographics and treatments that may contribute to identifying the new phenomenon of COVID lesions and how they differ from HAPU/Is.

Background: Patients may be educated about facial fractures using two-dimensional computed tomography (2DCT); however, three-dimensional mixed reality (3DMR) goggles may improve patient education by delivering content in an immersive environment. Objective: To compare the effectiveness of 2DCT and 3DMR formats used for patient education on facial fractures, as measured by surveys. Methods: In this prospective, randomized, crossover study, video tutorials intended for facial fracture informed consent were created in 2DCT and 3DMR formats from a single CT data set of a zygomaticomaxillary complex (ZMC) fracture. Subjects were randomly assigned into two groups. Group 1 (n = 25) viewed the 2DCT tutorial, answered self-assessment and information recall surveys, viewed the 3DMR tutorial, repeated the prior surveys as well as a comparison survey. Group 2 (n = 25) followed the same sequence but viewed the 3DMR tutorial and then the 2DCT tutorial. Results: Participants (n = 50) had no differences in age (group 1-51.9 years/standard deviation [SD] 20.9; group 2-44.7 years/SD 17.6 years; p = 0.223), gender (group 1-10 male/15 female; group 2-11 male/14 female; p = 0.999), college education level (group 1-25 yes; group 2-25 yes; p = 0.844), or prior 2DCT or 3DMR experience (group 1-9 yes/16 no; group 2-13 yes/12 no; p = 0.393). The 3DMR format was preferred over 2DCT (p < 0.05), and it was reported to enhance understanding as compared to 2DCT (p < 0.05). No differences for information recall were noted (p = 0.753). Conclusion: In this study, participants preferred 3DMR goggles over 2DCT for a simulated ZMC fracture-informed consent.
RESUMO
Coccidioides is an endemic fungus that causes infections ranging from mild respiratory illness to life-threatening disease, and immunocompromised hosts such as solid organ transplant recipients are at higher risk for disseminated infection and mortality. Our center administers fluconazole prophylaxis to kidney transplant recipients residing in geographic areas with higher incidences of coccidioidomycosis. However, because drug-drug interactions occur between triazoles and immunosuppressants used in transplant medicine, we undertook a study to ascertain whether fluconazole prophylaxis was associated with any important safety outcomes in kidney transplant recipients. This retrospective study evaluated patients who had undergone kidney transplantation between 2016 and 2019. Data on patient demographics, transplant-related clinical information, use of fluconazole prophylaxis (200 mg daily for 6-12 months post-transplant), and patient outcomes were obtained. The primary outcome was mean estimated glomerular filtration rate (eGFR) at 12 months, comparing those who received fluconazole prophylaxis to those who did not. Secondary outcomes included mean eGFR at 3 months, 6 months, and 9 months post-transplant, patient survival, biopsy-proven graft rejection, graft loss, or a new requirement for post-transplant dialysis, all within 12 months post-transplant. The mean eGFR at 12 months was similar between both groups, with 66.4 ml/min/1.73 m² in the fluconazole prophylaxis group vs. 64.3 ml/min/1.73 m² in the non-fluconazole prophylaxis group (P = 0.55). Secondary outcomes were similar across both groups. Multivariable linear regression found no significant association between fluconazole use and graft function. Fluconazole prophylaxis for prevention of coccidioidomycosis was not associated with adverse graft outcomes in kidney transplant recipients.
Solid organ transplant recipients can be highly immune suppressed, and infection with Coccidioides (valley fever) after transplant can lead to severe infections in these patients. Our study showed that fluconazole was safe and effective for preventing Coccidioides in kidney transplant recipients.

Fluid creep occurs when resuscitation after extensive burn injury reaches volumes higher than predicted. Since this has been described in patients with high opioid requirements, continuous analgesics and sedatives, including dexmedetomidine, have been avoided during resuscitation. This study sought to describe the impact of dexmedetomidine on fluid resuscitation requirements. This retrospective cohort study included adult patients with burns greater than 20% total body surface area (TBSA) resuscitated between January 2017 and June 2022 at a regional burn center. Patients deceased within 48 hours of burn were excluded. Primary outcome was volume of fluid required in the first 24 and 48 hours post-burn. Secondary outcomes were the incidence of fluid-related adverse events within 7 days post-burn. A total of 170 patients were included: 55 in the dexmedetomidine cohort and 115 in the control cohort. After propensity matching for variables associated with fluid creep, the dexmedetomidine cohort required 4.2 ± 1.7 mL/kg/%TBSA in the first 24 hours compared to 3.6 ± 1.1 mL/kg/%TBSA in the control cohort (p=0.03). The difference was no longer significant at 48 hours (p=0.11). There were no differences in the incidence of acute respiratory distress syndrome, delayed escharotomy/fasciotomy, intraabdominal hypertension, or renal replacement therapy. Dexmedetomidine exposure during acute resuscitation resulted in increased fluid requirements in the first 24 hours, suggesting it is independently associated with fluid creep; however, this increase was not sustained at 48 hours. Clinical significance of this finding is unclear as there was no increase in adverse events related to excessive fluid resuscitation between cohorts.
RESUMO
Background: Severe coccidioidomycosis presenting with respiratory failure is an uncommon manifestation of disease. Current knowledge of this condition is limited to case reports and small case series. Methods: A retrospective multicenter review of patients with coccidioidomycosis-associated acute respiratory distress syndrome (CA-ARDS) was conducted. It assessed clinical and laboratory variables at the time of presentation, reviewed the treatment course, and compared this cohort with a national database of patients with noncoccidioidomycosis ARDS. Survivors and nonsurvivors of coccidioidomycosis were also compared to determine prognostic factors. Results: In this study, CA-ARDS (n = 54) was most common in males, those of Hispanic ethnicity, and those with concurrent diabetes mellitus. As compared with the PETAL network database (Prevention and Early Treatment of Acute Lung Injury; n = 1006), patients with coccidioidomycosis were younger, had fewer comorbid conditions, and were less acidemic. The 90-day mortality was 15.4% for patients with coccidioidomycosis, as opposed to 42.6% (P < .0001) for patients with noncoccidioidomycosis ARDS. Patients with coccidioidomycosis who died, as compared with those who survived, were older, had higher APACHE II scores (Acute Physiology and Chronic Health Evaluation), and did not receive corticosteroid therapy. Conclusions: CA-ARDS is an uncommon but morbid manifestation of infection. When compared with a national database, the overall mortality appears favorable vs other causes of ARDS. Patients with CA-ARDS had a low overall mortality but required prolonged antifungal therapy. The utility of corticosteroids in this condition remains unconfirmed.
RESUMO
BACKGROUND. CT with adrenal-washout protocol (hereafter, adrenal-protocol CT) is commonly performed to distinguish adrenal adenomas from other adrenal tumors. However, the technique's utility among heterogeneous nodules is not well established, and the optimal method for placing ROIs in heterogeneous nodules is not clearly defined. OBJECTIVE. The purpose of our study was to determine the diagnostic performance of adrenal-protocol CT to distinguish adenomas from nonadenomas among heterogeneous adrenal nodules and to compare this performance among different methods for ROI placement. METHODS. This retrospective study included 164 patients (mean age, 59.1 years; 61 men, 103 women) with a total of 164 heterogeneous adrenal nodules evaluated using adrenal-protocol CT at seven institutions. All nodules had an available pathologic reference standard. A single investigator at each institution evaluated the CT images. ROIs were placed on portal venous phase images using four ROI methods: standard ROI, which refers to a single large ROI in the nodule's center; high ROI, a single ROI on the nodule's highest-attenuation area; low ROI, a single ROI the on nodule's lowest-attenuation area; and average ROI, the mean of the three ROIs on the nodule's superior, middle, and inferior thirds using the approach for the standard ROI. ROIs were then placed in identical locations on unenhanced and delayed phase images. Absolute washout was determined for all methods. RESULTS. The nodules comprised 82 adenomas and 82 nonadenomas (36 pheochromocytomas, 20 metastases, 12 adrenocortical carcinomas, and 14 nodules with other pathologies). The mean nodule size was 4.5 ± 2.8 (SD) cm (range, 1.6-23.0 cm). Unenhanced CT attenuation of 10 HU or less exhibited sensitivity and specificity for adenoma of 22.0% and 96.3% for standard-ROI, 11.0% and 98.8% for high-ROI, 58.5% and 84.1% for low-ROI, and 30.5% and 97.6% for average-ROI methods. Adrenal-protocol CT overall (unenhanced attenuation ≤ 10 HU or absolute washout of ≥ 60%) exhibited sensitivity and specificity for adenoma of 57.3% and 84.1% for the standard-ROI method, 63.4% and 51.2% for the high-ROI method, 68.3% and 62.2% for the low-ROI method, and 59.8% and 85.4% for the average-ROI method. CONCLUSION. Adrenal-protocol CT has poor diagnostic performance for distinguishing adenomas from nonadenomas among heterogeneous adrenal nodules regardless of the method used for ROI placement. CLINICAL IMPACT. Adrenal-protocol CT has limited utility in the evaluation of heterogeneous adrenal nodules.

OBJECTIVE: We investigated whether the associations of serum adiponectin, leptin, and resistin with adiposity differ with menopausal age. METHODS: In this cross-sectional study, we included 751 postmenopausal women from the Multi-Ethnic Study of Atherosclerosis (MESA) who reported their menopausal age (<45, 45-49, 50-54 and ≥55 y) and had anthropometrics, serum adipokines, and abdominal computed tomography measures of visceral and subcutaneous adipose tissue (VAT and SAT) obtained at MESA exam 2 or 3. Linear regression models were used for analysis. RESULTS: The mean ± SD age was 65.1 ± 9.0 years for all participants. The median (interquartile range) values for serum adiponectin, leptin and resistin, VAT, and SAT were 21.9 (14.8-31.7) ng/L, 24.3 (12.5-42.4) pg/L, 15.3 (11.8-19.5) pg/L, 183.9 (130.8-251.1) cm2, and 103.7 (65.6-151.5) cm2, respectively. The mean ± SD values for body mass index, waist circumference, and waist-to-hip ratio were 28.3 ± 5.81 kg/m2, 96.6 ± 15.9 cm, and 0.91 ± 0.078, respectively. Adiponectin was inversely associated with all adiposity measures, with similar patterns across menopausal age categories. Leptin was positively associated with all adiposity measures, and the strength of associations varied across menopausal age categories for body mass index, waist circumference, and SAT (Pinteraction ≤ 0.01 for all). The associations of resistin with adiposity measures were mostly nonsignificant except in the 45- to 49-year menopausal age category. CONCLUSIONS: Menopausal age category had no influence on the association of serum adiponectin with adiposity. The association of serum leptin and resistin differed according to menopausal age category for generalized adiposity but was inconsistent for measures of abdominal adiposity.

BACKGROUND: This prospective study assessed the accuracy of MRI and ultrasound (US) measurements as a preprocedural assessment tool for predicting clinical loss of resistance depth (CLORD) during fluoroscopy-guided lumbar epidural steroid injections (ESIs). MATERIALS AND METHODS: Sixty patients enrolled received lumbar ESIs at an academic chronic pain clinic. The MRI measurement calculated the distance between the skin and the posterior epidural space, while US measurements included transverse and parasagittal oblique views of the interlaminar space. The epidural space measurements were compared with the CLORD during the performance of the prone epidural injections. The differences in measurements were analyzed using two one-sided tests for equivalency with a 0.5 equivalency margin. The intraclass correlation coefficients between CLORD and the imaging modalities were estimated using mixed effects models. RESULTS: MRI was equivalent to CLORD with a mean difference of -0.2 cm (95% CI -0.39 to -0.11). US transverse and US parasagittal oblique measurements were not equivalent to and underestimated CLORD with mean differences of -0.98 cm (90% CI -1.8 to -0.77) and -0.79 cm (90% CI -1.0 to -5.9), respectively. The intraclass correlation coefficients between MRI and CLORD were the highest at 0.85, compared with 0.65 and 0.73 for transverse and parasagittal oblique US views, respectively. CONCLUSIONS: MRI measurements are preferable over US for preprocedural assessment of patients receiving lumbar ESIs for predicting CLORD.
RESUMO
The incidence of coccidioidomycosis continues to increase. The diagnosis frequently relies on non-invasive diagnostic testing with immunodiffusion and complement fixation (CF) testing the current gold standard. A direct comparison of quantitative immunodiffusion and CF for IgG antibodies has not been previously reported. In a comparison of 368 samples, there was close concordance observed (360/368 = 97.8%) (P-value < .001). These tests can be considerably interchangeable in the reference laboratory setting.
There are several diagnostic methodologies available in coccidioidomycosis. Direct comparisons of these methods are limited. Prior studies have not compared quantitative immunodiffusion to complement fixation testing. Our results show these tests are highly concordant.

Purpose: A complication of cancer-directed therapy that often goes undiscussed is infertility. Although guidelines recommend addressing the possibility of infertility and fertility preservation approaches before initiating treatment, an internal review at our institution showed only 49% of female patients had infertility risk counseling documented. As a result, a fertility assessment communication was added into all oncology treatment plans to improve rates of fertility discussion and documentation. Methods: This retrospective observational study included newly diagnosed patients of childbearing potential who initiated cancer-directed therapy between January 1, 2020, and October 31, 2021. Patients who were no longer of childbearing potential due to age or surgery were excluded. Patients were divided into pre- and post-implementation groups to assess the impact of the fertility assessment communication implemented on November 1, 2020. Results: A total of 152 patients met inclusion criteria, with 80 patients in the pre-implementation group and 72 patients in the post-implementation group. The primary outcome of documentation of infertility risk discussion was 47.5% in the pre-implementation group and 86.1% in the post-implementation group (p < 0.0001). Discussion of fertility preservation options was documented in 28.7% of the pre-implementation group and 43.1% in the post-implementation group (p = 0.13). In the pre-implementation group, 5% underwent fertility preservation versus 27.8% in the post-implementation group (p = 0.0001). Of the 27 patients who received fertility preservation, 13 received hormonal therapy, 11 sperm banking, and 3 egg harvesting. Conclusion: This intervention significantly increased rates of infertility risk discussion and fertility preservation approaches received. There are opportunities to help patients receive fertility preservation, especially sperm banking and egg harvesting.

OBJECTIVE: To evaluate the association of maternal delivery history with a brachial plexus birth injury risk in subsequent deliveries and to estimate the effect of subsequent delivery method on brachial plexus birth injury risk. METHODS: We conducted a retrospective cohort study of all live-birth deliveries occurring in California-licensed hospitals from 1996 to 2012. The primary outcome was recurrent brachial plexus birth injury in a subsequent pregnancy. The exposure was delivery history (parity, shoulder dystocia in a previous delivery, or previously delivering a neonate with brachial plexus birth injury). Multiple logistic regression was used to model adjusted associations of delivery history with brachial plexus birth injury in a subsequent pregnancy. The adjusted risk and adjusted risk difference for brachial plexus birth injury between vaginal and cesarean deliveries in subsequent pregnancies were determined, stratified by delivery history, and the number of cesarean deliveries needed to prevent one brachial plexus birth injury was determined. RESULTS: Of 6,286,324 neonates delivered by 4,104,825 individuals, 7,762 (0.12%) were diagnosed with a brachial plexus birth injury. Higher parity was associated with a 5.7% decrease in brachial plexus birth injury risk with each subsequent delivery (adjusted odds ratio [aOR] 0.94, 95% CI 0.92-0.97). Shoulder dystocia or brachial plexus birth injury in a previous delivery was associated with fivefold (0.58% vs 0.11%, aOR 5.39, 95% CI 4.10-7.08) and 17-fold (1.58% vs 0.11%, aOR 17.22, 95% CI 13.31-22.27) increases in brachial plexus birth injury risk, respectively. Among individuals with a history of delivering a neonate with a brachial plexus birth injury, cesarean delivery was associated with a 73.0% decrease in brachial plexus birth injury risk (0.60% vs 2.21%, aOR 0.27, 95% CI 0.13-0.55) compared with an 87.9% decrease in brachial plexus birth injury risk (0.02% vs 0.15%, aOR 0.12, 95% CI 0.10-0.15) in individuals without this history. Among individuals with a history of brachial plexus birth injury, 48.1 cesarean deliveries are needed to prevent one brachial plexus birth injury. CONCLUSIONS: Parity, previous shoulder dystocia, and previously delivering a neonate with brachial plexus birth injury are associated with future brachial plexus birth injury risk. These factors are identifiable prenatally and can inform discussions with pregnant individuals regarding brachial plexus birth injury risk and planned mode of delivery.

Though specific growth rate (SGR) has potential prognostic value for oropharyngeal squamous cell carcinoma (OPSCC), there is sparse literature defining these rates. Our aims were to establish the SGRs of primary tumors (PTs) and lymph nodes (LNs) in OPSCC and to correlate SGR with oncologic outcome. A pilot study was designed with a retrospective analysis examining 54 patients from the University of California, Davis with OPSCC (diagnosed 2012-2019). Radiation oncology software and pretreatment serial CT scans were used to measure PT and LN volumes to calculate SGR and doubling time (DT). The mean PT-SGR was 1.2 ± 2.2%/day and the mean LN-SGR was 1.6 ± 1.9%/day. There was no statistically significant difference between slow-growing and fast-growing cohorts in terms of age, gender, smoking status, tumor subsite, HPV status (as determined with p16 staining), initial volume, or overall stage. SGR had no impact on 2-year overall survival, disease-free survival, or disease-specific survival. We found the average daily growth rates for OPSCC to be 1.2%/day and 1.6%/day. Our findings suggest PT- and LN-SGR are independent factors, not heavily influenced by known biomarkers and patient characteristics, without a statistical impact on prognosis. This information has value in patient counseling regarding tumor growth and in providing patients worried about fast-growing tumors the appropriate reassurance.
RESUMO
OBJECTIVE: Historically, early surgical management of frontal sinus outflow tract (FSOT) fractures has been standard practice. There has been a paradigm shift toward nonsurgical or delayed management. Unfortunately, clinical indications and treatment outcomes for this approach are poorly understood. This study evaluates radiologic indicators, as well as sinus reaeration and complication rates for FSOT injuries treated nonsurgically. STUDY DESIGN: A retrospective cohort study of FSOT injuries between 2005 and 2019. SETTING: Academic, tertiary care medical center. METHODS: Radiographic fracture patterns of the frontal ostia (FO) and frontal recess (FR) were recorded as either patent, disrupted, or obstructed. Sinus reaeration, surgical rescue, and complication rates were documented. Patients with follow-up imaging >42 days were included. Patients undergoing immediate surgical intervention were excluded. RESULTS: One hundred patients were identified and 44 met the criteria (88 sinuses). Among nonobstructed FSOT injuries (ie, patent or disrupted), reaeration occurred in 91% of the FO and 98% of FR injuries. Two sinuses required surgical rescue including 1 Draf IIB (1%), and 1 obliteration (1%). Two sinuses had complications including 1 mucocele (1%) and 1 cerebrospinal fluid leak (1%). FO and FR fracture patterns had no identifiable correlation with long-term reaeration rates or the need for surgical intervention. CONCLUSION: Among nonobstructive injuries to the FSOT, average reaeration rates in observed patients were high (91%-98%). Rescue surgery (2%) and complication rates (2%) were low, suggesting that nonsurgical management of nonobstructed FSOT is a viable strategy. No radiographic features were clearly identified to be predictive of sinus reaeration.

BACKGROUND: Infection after tumor resection and endoprosthetic reconstruction is a potentially limb-threatening complication. The duration of surgery has been shown to be a risk factor for infection, but the ability of an extended duration of postoperative prophylactic antibiotics to potentially minimize that risk has not been specifically studied. The objective of this study was to determine whether extended postoperative antibiotic therapy protects against surgical site infection (SSI) in the setting of prolonged surgical duration in patients undergoing endoprosthetic reconstruction after tumor resection. METHODS: This study was a planned secondary analysis of the Prophylactic Antibiotic Regimens in Tumor Surgery (PARITY) trial data set. Patients in the PARITY trial were randomized to receive 24 hours or 5 days of postoperative prophylactic antibiotics. The current study assessed the risk of SSI in those cohorts on the basis of surgical duration. A multivariable regression model was used to examine the adjusted effects of the duration of surgery on SSI, after controlling for other significant risk factors and potential confounders. RESULTS: All 604 patients who had been included in the final data analysis in the PARITY trial were also included in this secondary analysis. Those who sustained an SSI had a greater mean duration of surgery (6.2 hours) compared with those who did not sustain an SSI (4.9 hours, p < 0.0001). There was no specific time point at which the risk of infection significantly increased. Extended postoperative prophylactic antibiotic therapy did not appear to mitigate the risk of SSI even in patients with prolonged surgical duration. CONCLUSIONS: Increased surgical duration was an independent risk factor for SSI in orthopaedic patients undergoing endoprosthetic reconstruction after tumor resection. However, surgical duration is multifactorial and is influenced by several variables. For example, there may be protective features of flap coverage that increase surgical duration while paradoxically decreasing the risk of SSI. Extended postoperative antibiotic therapy did not mitigate the risk of infection in this cohort, and other risk mitigation strategies will need to be considered in future studies. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVES: Patients with intrauterine fetal demise (IUFD) are at higher risk of complications when undergoing dilation and evacuation (D&E) compared to patients undergoing abortion for other indications. We aimed to compare baseline characteristics and describe outcomes, including frequencies of complications such as disseminated intravascular coagulation (DIC) and hemorrhage, in patients undergoing D&E for IUFD vs induced abortion, with a goal of identifying associated risk factors for complications. STUDY DESIGN: We conducted a retrospective matched cohort study of patients undergoing nonemergent D&Es for singleton ≥14-0/7-week IUFD January 1, 2019 to May 31, 2021, matched with two patients undergoing induced second-trimester D&Es by cesarean delivery history, patient age, and gestational age (GA). We collected demographics, history, GA, coagulation studies, quantitative blood loss (QBL), and complications. We calculated descriptive statistics and tested for association using chi-square, Fisher's exact, t, and Wilcoxon's rank sum tests. RESULTS: Of 1390 procedures, 64 patients with IUFD met inclusion criteria and were matched with 128 patients undergoing induced D&E. Eight (12.5%) patients with IUFD and six (4.7%) undergoing induced D&E had hemorrhage (odds ratio [OR] = 2.90, 95% confidence interval [0.96, 8.77]). Six (9.4%) patients with IUFD and none undergoing induced D&E had DIC (OR = 28.56 [1.58, 515.38]). Median QBL was 75.0 mL (50, 162.5) for patients with IUFD vs 110.0 mL (50, 200) for those undergoing induced D&E (p = 0.083). Twelve (18.8%) patients with IUFD vs seven (5.5%) undergoing induced D&E received at least one intervention due to bleeding complications (p = 0.004). CONCLUSIONS: We found a higher DIC frequency but no significant difference in hemorrhage or QBL in IUFD D&E compared to induced abortion. Our IUFD D&E complication frequency is higher than those previously published. IMPLICATIONS: Our results affirm current standards of care for D&E in patients with IUFD. Large referral centers may have higher proportions of complications compared to other sites.

OBJECTIVE: To compare unfractionated heparin (UFH) monitoring using time in therapeutic range of activated partial thromboplastin time (aPTT) versus anti-factor Xa activity (anti-Xa) in children. METHODS: This retrospective chart review, with data between October 2015 and October 2019, included pediatric patients younger than 18 years on therapeutic UFH infusion with aPTT or anti-Xa monitoring. Patients receiving extracorporeal membrane oxygenation, dialysis, concomitant anticoagulants, prophylactic UFH, no stated goal, and UFH administered for less than 12 hours were excluded. The primary outcome compared the percentage of time in therapeutic range between aPTT and anti-Xa. Secondary outcomes included time to first therapeutic value, UFH infusion rates, mean rate adjustments, and adverse events. RESULTS: A total of 65 patients were included, with 33 aPTT patients and 32 anti-Xa patients, representing 39 UFH orders in each group. Baseline characteristics were similar between groups, with an overall mean age of 1.4 years and mean weight of 6.7 kg. The anti-Xa cohort demonstrated a statistically significantly higher percentage of time in therapeutic range compared with the aPTT group (50.3% vs 26.9%, p = 0.002). The anti-Xa group also demonstrated a trend toward decreased time to first therapeutic value compared with aPTT (14 vs 23.2 hours, p = 0.12). Two patients in each group experienced new or worsening thrombosis. Six patients in the aPTT cohort experienced bleeding. CONCLUSIONS: This study demonstrated greater time was spent within therapeutic range for children receiving UFH monitored with anti-Xa compared with aPTT. Future studies should assess clinical outcomes in a larger population.
RESUMO
AIMS: The purpose of this study is to evaluate the accuracy and validity of the determination of cause of death (COD) and manner of death (MOD) at the completion of the forensic autopsy prosection. METHODS: We analysed 952 autopsy cases conducted from 2019 to 2020 and compared every patient's COD, other significant contributing factors to death (OSC), and MOD after prosection to their COD, OSC and MOD after completion of the final autopsy report. RESULTS: We found that 83% of cases (790 patients) did not have an unexpected change and 17% of cases (162 patients) exhibited a true change in their final diagnosis; the relationship between age and changes in COD and MOD was significant. CONCLUSIONS: Our findings indicate that in the majority of forensic autopsy cases, medical professionals can reasonably complete death certification after the autopsy prosection. In addition to improving the accuracy of COD and MOD, advances in this field will enhance timely decedent affairs management, timely investigations of crimes and timely closure to families who have lost loved ones. We recommend implementing combined interventional education and consultation with expert pathologists, and a well-followed structured method of death classification as the best course of practice.
