Abstract
This study aimed to evaluate the residual effect of narasin on intake and ruminal fermentation parameters in Nellore cattle fed a forage-based diet. Thirty rumen-cannulated Nellore steers [initial body weight (BW) = 281 ± 21 kg] were allocated to individual pens in a randomized complete block design, with 10 blocks and 3 treatments, defined according to the fasting BW at the beginning of the experiment. The animals were fed a forage-based diet containing 99% Tifton-85 haylage and 1% concentrate. Within blocks, animals were randomly assigned to one of three treatments: (1) forage-based diet without addition of narasin (CON; n = 10), (2) CON diet plus 13 mg of narasin/kg DM (N13; n = 10), or (3) CON diet plus 20 mg of narasin/kg DM (N20; n =10). The experiment lasted 156 d and was divided into two periods. The first period lasted 140 d and consisted of the daily supply of narasin. In the second period (last 16 d), the animals were not supplemented with narasin when the residual effect of the additive was evaluated. The treatments were evaluated by linear and quadratic orthogonal contrasts. The results were reported as least square means and the effect was considered significant when P ≤ 0.05. No treatment × day interaction was identified for dry matter intake (P = 0.27). There was a treatment × day (P ≤ 0.03) interaction after narasin removal for the molar proportion of acetate, propionate, ac:prop ratio, and ammonia nitrogen. The inclusion of narasin decreased linearly (P &lt; 0.01) the molar proportion of acetate (P &lt; 0.01), and this effect persisted until day 5 after narasin withdrawal (P &lt; 0.01). Narasin inclusion linearly increased the molar proportion of propionate (P &lt; 0.04), and linearly decreased (P &lt; 0.01) ac:prop ratio up to 5 d after removing narasin from the diets. No treatment effects were observed (P &gt; 0.45) on days 8 and 16 after the withdrawal. Narasin linearly decreased ammonia nitrogen up to 1 day after withdrawal (P &lt; 0.01). In conclusion, the use of narasin for a prolonged period (140 d) resulted in a residual effect on rumen fermentation parameters after the removal of the additive from the diets.

AbstractSupplementing growing cattle grazing native subtropical Campos grasslands during winter improves the low, even negative, average daily weight gain (ADG) typical of extensive animal production systems in Uruguay. Nonetheless, to render the practice profitable, it is crucial to control supplement feed efficiency (SFE), that is, the difference in ADG between supplemented and control animals (ADGchng) per unit of supplement dry matter (DM) intake. Little has been studied specifically on how SFE varies in these systems. The objective of this study was to quantify the magnitude and variation in SFE of growing beef cattle grazing stockpiled native Campos grasslands during winter and assess putative associations with herbage, animals, supplements, and climatic variables. We compiled data from supplementation trials carried out in Uruguay between 1993 and 2018, each evaluating between one and six supplementation treatments. The average ADG of unsupplemented and supplemented animals were 0.13 ± 0.174 and 0.49 ± 0.220 kg/animal/day, respectively. In both cases, ADG decreased linearly as the proportion of green herbage in the grazed grassland was lower, but the ADG of unsupplemented animals was further reduced when winter frosts were numerous. Estimated SFE were moderately high, with an average of 0.21 ± 0.076 ADGchng/kg DM, resulting from average ADGchng of 0.38 ± 0.180 kg/animal/day in response to an average supplementation rate of 1.84 ± 0.68 kg supplement DM intake/animal/day (0.86%  ± 0.27% body weight). No association was found between SFE and supplementation rate or type (protein vs. energy-based; P &gt; 0.05), but forage allowance negatively affected it, and herbage mass positively affected it, yet in a smaller magnitude, suggesting that a balance is needed between the two to maximize SFE. Weather conditions during trials affected SFE (P &lt; 0.05), with greater SFE in winters with lower temperatures and more frosts. Daytime grazing time was consistently lower in supplemented animals compared to their unsupplemented counterparts, whereas ruminating time during the day was similar, increasing as the proportion of green herbage decreased. Herbage intake estimated from energy balance suggested the existence of some substitution effect. This agrees with the moderately high SFE and with the total digestible nutrients-to-protein ratio of these subtropical humid grasslands being higher than in semi-arid rangelands and dry-season tropical pastures but lower than in sown pastures.

Abstract

Objective
Feeding intolerance (FI) is a common condition in preterm infants because they have an immature gastrointestinal tract. There are studies on the effects of the position on gastric residual volume (GRV) in preterm infants. Kangaroo mother care (KMC) may be an instrument for reducing FI by providing an upright position to infants. Moreover, numerous studies conducted with this therapeutic position applied by putting an infant on the mother’s chest have indicated its positive effects on the infant’s weight gain, growth and development, and vital signs. Therefore, this study aimed to reveal the impact of KMC on FI in preterm infants.

Methods
The population of the study, designed as a randomized trial, consisted of 168 preterm infants [KMC: 84, Standart Care (SC): 84] hospitalized in the neonatal intensive care unit of a university hospital between June and November 2020. Infants were randomly selected and divided into two groups. After the vital signs of the infants in both groups became stable, the infants were fed in the same position. KMC was applied to the infants in the intervention group for 1 h by preparing a suitable environment after feeding. Infants in the SC group were placed in the prone position after feeding. The GRVs of the infants in both groups were recorded on the Infant Follow-up Form before the next feeding.

Results
No statistically significant difference was detected between the groups upon comparing them in terms of demographic and clinical characteristics. The body temperatures and O2 saturations of the participants in the KMC group were statistically significantly higher, and their respiratory and heart rates were lower than the SC group. The transition time to full enteral feeding was statistically significantly shorter, and FI was experienced significantly less in the KMC group infants than in the SC group (p &lt; 0.05). There was no statistically significant difference between the groups in terms of the infants' weight gain and length of hospital stay (p &gt; 0.05).

Conclusion
The present study demonstrated that KMC had a positive impact on FI in preterm infants. KMC is not only a safe care model providing the earliest contact between parents and infants but also a practice whose positive effect on the functioning of the digestive system in preterm infants we can use.

Published: March 2023

Objective
The aim of the study is to describe the impact of colocating COVID-19 vaccinations with local syringe service programs on vaccine completion among people who inject drugs.

Methods
Data were derived from 6 community-based clinics. People who inject drugs who received at least one COVID-19 vaccine from a colocated clinic partnering with a local syringe service program were included in the study. Vaccine completion was abstracted from electronic medical records; additional vaccinations were abstracted using health information exchanges embedded within the electronic medical records.

Results
Overall, 142 individuals with a mean age of 51 years, predominantly male (72%) and Black, non-Hispanic (79%) received COVID-19 vaccines. More than half elected to receive a 2-dose mRNA vaccine (51.4%). Eighty-five percent completed a primary series, and 71% of those who received a mRNA vaccine completed the 2-dose series. Booster uptake was 34% in those completing a primary series.

Conclusions
Colocated clinics are an effective means of reaching vulnerable populations. As the COVID-19 pandemic continues and need for annual booster vaccines arises, it is important to bolster public support and funding to continue low-barrier preventive clinics colocated with harm reduction services for this population.
Disseminating MSSA Infection in a Preterm Infant With Rare Finding of Spinal Epidural Abscess
Authors: Huneycutt Tamatha M. , Carlson Cheryl , Newberry Desi M. 
Published: March 2023

Background:Methicillin-susceptibleStaphylococcus aureus(MSSA) occurs more frequently in the neonatal intensive care unit (NICU) than methicillin-resistantS. aureus(MRSA) and can result in comparable morbidity and mortality in the neonatal population. MSSA infection may present as pustulosis or cellulitis and evolve into bacteremia, pneumonia, endocarditis, brain abscesses, and osteomyelitis. There is a paucity of literature regarding the treatment and long-term outcomes in the premature infant.Clinical Findings:A 32-week twin developed MSSA sepsis with presentation of pain, decreased movement of upper extremities, and global hypotonia. Blood cultures remained positive despite antibiotic coverage.Primary Diagnosis:The infant was admitted to the level IV NICU with the diagnosis of MSSA bacteremia, with concern for dissemination and osteomyelitis.Interventions:Diagnostic studies included laboratory testing for sepsis evaluation, radiologic studies to evaluate for dissemination, immunologic testing to rule out complement deficiency, and hematology testing to rule out hypercoagulable conditions.Outcomes:Diagnostic testing showed extensive cellulitis, osteomyelitis, multiple liver abscesses, and epidural abscesses suggestive of spinal epidural abscess (SEA). Abscess debridement and irrigation on the left distal femur, left elbow, and right tibia were performed. The infant completed 8 weeks of IV antibiotic therapy. Immunologic and hematology testing was within normal limits.Practice Recommendations:Prompt recognition and follow-up for clinical signs of sepsis are vital when caring for premature infants. Inclusion of pediatric subspecialist recommendations to assure all diagnostic studies and treatments are completed can significantly impact the patient's outcome. Long-term follow-up is needed for premature infants with the diagnosis of SEA.

OBJECTIVE:
To compare quality of life (QOL) among patients with endometrial intraepithelial neoplasia or early-stage endometrial cancer and stress urinary incontinence (SUI) who chose to have concomitant surgery with cancer surgery alone.

METHODS:
A multicenter, prospective cohort study was conducted across eight U.S. sites. Potentially eligible patients were screened for SUI symptoms. Those who screened positive were offered referral to urogynecology and incontinence treatment, including concomitant surgery. Participants were categorized into two groups: 1) concomitant cancer and SUI surgery or 2) cancer surgery alone. The primary outcome was cancer-related QOL as measured by the FACT-En (Functional Assessment of Cancer Therapy–Endometrial) (range 0–100; higher score indicates better QOL). The FACT-En and questionnaires assessing urinary symptom–specific severity and effects were assessed before surgery and 6 weeks, 6 months, and 12 months after surgery. Adjusted median regression accounting for clustering was used to examine the relationship between SUI treatment group and FACT-En scores.

RESULTS:
Of 1,322 (53.1%) patients, 702 screened positive for SUI with 532 analyzed; 110 (21%) chose concomitant cancer and SUI surgery, and 422 (79%) chose cancer surgery alone. FACT-En scores increased for both the concomitant SUI surgery and cancer surgery–only groups from the preoperative to the postoperative period. After adjustment for timepoint and preoperative covariates, the median change in FACT-En score (postoperative−preoperative) was 1.2 points higher (95% CI −1.3 to 3.6) for the concomitant SUI surgery group compared with the cancer surgery–only group across the postoperative period. Median time until surgery (22 days vs 16 days; P<.001), estimated blood loss (150 mL vs 72.5 mL; P<.001), and operative time (185.5 minutes vs 152 minutes; P<.001) were all greater for the concomitant cancer and SUI surgery group compared with the cancer-only group, respectively.

CONCLUSION:
Concomitant surgery did not result in improved QOL compared with cancer surgery alone for endometrial intraepithelial neoplasia and patients with early-stage endometrial cancer with SUI. However, FACT-En scores were improved in both groups.

Published: March 2023

OBJECTIVE:
To evaluate the risk of recurrence and reintervention after uterine-sparing treatment options for symptomatic adenomyosis, including adenomyomectomy, uterine artery embolization (UAE), and image-guided thermal ablation.

DATA SOURCES:
We searched electronic databases such as Web of Science, MEDLINE, Cochrane Library, EMBASE, ClinicalTrials.gov, and Google Scholar from January 2000 to January 2022. The search was conducted using the following search terms: “adenomyosis,” “recurrence,” “reintervention,” “relapse,” and “recur.”

METHODS OF STUDY SELECTION:
All studies that described the risk of recurrence or reintervention after uterine-sparing interventions for symptomatic adenomyosis were reviewed and screened according to the eligibility criteria. Recurrence was defined as the reappearance of symptoms (painful menses or heavy menstrual bleeding) after significant or complete remission, or the reappearance of adenomyotic lesions confirmed by ultrasonography or magnetic resonance imaging.

TABULATION, INTEGRATION, AND RESULTS:
The outcome measures were presented as the frequency with percentage and pooled with 95% CI. A total of 42 studies (single-arm retrospective and prospective studies) that represented 5,877 patients were included. The recurrence rates after adenomyomectomy, UAE, and image-guided thermal ablation were 12.6% (95% CI 8.9–16.4%), 29.5% (95% CI 17.4–41.5%), and 10.0% (95% CI 5.6–14.4%), respectively. The reintervention rates were 2.6% (95% CI 0.9–4.3%), 12.8% (95% CI 7.2–18.4%), and 8.2% (95% CI 4.6–11.9%) after adenomyomectomy, UAE, and image-guided thermal ablation, respectively. Subgroup analysis and sensitivity analysis were performed, and the heterogeneity was reduced in several analyses.

CONCLUSION:
Uterine-sparing techniques were successful in treating adenomyosis with low reintervention rates. Uterine artery embolization had higher recurrence and reintervention rates than other techniques; however, patients treated with UAE had larger uteri and larger adenomyosis, indicating that selection bias may influence these results. More randomized controlled trials with a larger population are needed in the future.

Published: March 2023

OBJECTIVE:
To compare stillbirth rates per week of expectant management stratified by birth weight in pregnancies complicated by gestational diabetes mellitus (GDM) or pregestational diabetes mellitus.

METHODS:
A national population-based retrospective cohort study of singleton, nonanomalous pregnancies complicated by pregestational diabetes or GDM was performed using national birth and death certificate data from 2014 to 2017. Stillbirth rates per 10,000 patients (stillbirth incidence at gestational age week/ongoing pregnancies−[0.5×live births at gestational age week]) were determined for each week of pregnancy from 34 to 39 completed weeks of gestation. Pregnancies were stratified by birth weight, categorized as having small-for-gestational-age (SGA), appropriate-for-gestational-age (AGA), or large-for-gestational-age (LGA) fetuses, assigned by sex-based Fenton criteria. Relative risk (RR) and 95% CI for stillbirth were calculated for each gestational age week compared with the GDM-related AGA group.

RESULTS:
We included 834,631 pregnancies complicated by either GDM (86.9%) or pregestational diabetes (13.1%) in the analysis, with a total of 3,033 stillbirths. Stillbirth rates increased with advancing gestational age for pregnancies complicated by both GDM and pregestational diabetes regardless of birth weight. Compared with pregnancies with AGA fetuses, those with both SGA and LGA fetuses were significantly associated with an increased risk of stillbirth at all gestational ages. Ongoing pregnancies at 37 weeks of gestation complicated by pregestational diabetes with LGA or SGA fetuses had respective stillbirth rates of 64.9 and 40.1 per 10,000 patients. Pregnancies complicated by pregestational diabetes had an RR of stillbirth of 21.8 (95% CI 17.4–27.2) for LGA fetuses and 13.5 (95% CI 8.5–21.2) for SGA fetuses compared with GDM-related AGA at 37 weeks of gestation. The greatest absolute risk of stillbirth was in pregnancies complicated by pregestational diabetes at 39 weeks of gestation with LGA fetuses (97/10,000).

CONCLUSION:
Pregnancies complicated by both GDM and pregestational diabetes affected by pathologic fetal growth have an increased risk of stillbirth with advancing gestational age. This risk is significantly higher with pregestational diabetes, especially pregestational diabetes with LGA fetuses.
Determinants of Cost for Outpatient Hysterectomy for Benign Indications in a Nationwide Sample
Authors: Whiteside James L. , Tumin Dmitry , Hohmann Samuel F. , Harris Alyssa 
Published: March 2023

OBJECTIVE:
To identify surgeon-level variation in cost to produce an outpatient hysterectomy for benign indications in the United States.

METHODS:
A sample of patients undergoing outpatient hysterectomy in October 2015 to December 2021, excluding those with a diagnosis of gynecologic malignancy, was obtained from the Vizient Clinical Database. The primary outcome was total direct hysterectomy cost, which is a modeled cost to produce care. Patient, hospital, and surgeon covariates were analyzed with mixed-effects regression, which included surgeon-level random effects to capture unobserved differences influencing cost variation.

RESULTS:
The final sample included 264,717 cases performed by 5,153 surgeons. The median total direct cost of hysterectomy was $4,705 (interquartile range $3,522–6,234). Cost was highest for robotic hysterectomy ($5,412) and lowest for vaginal hysterectomy ($4,147). After all variables were included in the regression model, approach was the strongest of the observed predictors, but 60.5% of the variance in costs was attributable to unexplained surgeon-level differences, implying a difference in costs between the 10th and 90th percentiles of surgeons of $4,063.

CONCLUSION:
The largest observed determinant of cost to produce an outpatient hysterectomy for benign indications in the United States is approach, but differences in cost are attributable primarily to unexplained differences among surgeons. Standardization of surgical approach and technique and surgeon awareness of surgical supply costs could address these unexplained cost variations.

OBJECTIVE:
To assess the incidence and risk factors for postpartum opioid overdose death and describe other causes of postpartum death in individuals with opioid use disorder (OUD).

METHODS:
We conducted a cohort study that used health care utilization data from the Medicaid Analytic eXtract linked to the National Death Index in the United States from 2006 to 2013. All pregnant individuals with live births or stillbirths and continuous enrollment for 3 months before delivery were eligible, including 4,972,061 deliveries. A subcohort of individuals with a documented history of OUD in the 3 months before delivery was identified. We estimated the cumulative incidence of death as occurring between delivery and 1 year postpartum among all individuals and individuals with OUD. Risk factors for opioid overdose death were assessed using odds ratios (ORs) and descriptive statistics, including demographics, health care utilization, obstetric conditions, comorbidities, and medications.

RESULTS:
The incidence of postpartum opioid overdose death per 100,000 deliveries was 5.4 (95% CI 4.5–6.4) among all individuals and 118 (95% CI 84–163) among individuals with OUD. Individuals with OUD had a sixfold higher incidence of all-cause postpartum death than all individuals. Common causes of death in individuals with OUD were other drug- and alcohol-related deaths (47/100,000), suicide (26/100,000), and other injuries, including accidents and falls (33/100,000). Risk factors strongly associated with postpartum opioid overdose death included mental health and other substance use disorders. Among patients with OUD, postpartum use of medication to treat OUD was associated with 60% lower odds of opioid overdose death (OR 0.4, 95% CI 0.1–0.9).

CONCLUSION:
Postpartum individuals with OUD have a high incidence of postpartum opioid overdose death and other preventable deaths, including nonopioid substance-related injuries, accidents, and suicide. Use of medications for OUD is strongly associated with lower opioid-related mortality.
