Case report and mini-review: Sarcina ventriculi in the stomach of an 80-year-old female.

Sarcina ventriculi, also known as Zymosarcina ventriculi and, incorrectly, as Clostridium ventriculi, is rarely encountered in clinical settings. A patient with a complicated gastrointestinal (GI) history, who was acutely presenting with small-bowel obstruction, was found to be colonized by S. ventriculi. The distinctive morphology of this species, with large Gram-variable cocci (up to 3 µm) arranged in two-by-two cuboid clusters reaching up to 20 µm, was key in identifying this bacterium in a stomach biopsy specimen. Sarcina ventriculi appears to be ubiquitously found in nature, and related bacterial species can cause GI-related disease in various animals. Clinical manifestations in humans are broad and often related to other underlying comorbidities. Isolation of S. ventriculi in the laboratory requires anaerobic culture on select media but its absence from standard MALDI-TOF databases complicates identification. Susceptibility data do not exist, so empiric treatment is the only option for this rare pathogen.

Opioid Prescribing Behavior in the Emergency Department During Routine Orthopedic Manipulations.

BACKGROUND: The emergency department (ED) often represents the first exposure orthopedic trauma patients have to prescription opioids and thus a critical opportunity for prevention of potential long-term opioid use. This study will analyze the impact of opioid prescribing patterns among both ED providers and orthopedic surgery residents on the utilization of opioids during routine orthopedic trauma manipulations. MATERIALS AND METHODS: This retrospective study reviewed opioid utilization among patients with an ankle or distal radius fracture at a large, urban, level 1 trauma center. Data on clinical providers, patient demographics, and injury severity score (ISS) were collected. Total opioid use was reported in oral morphine milligram equivalents (MME). Regression analyses were performed to determine how provider opioid prescribing intensity affected administered MME. RESULTS: Five-hundred and ninety-five patients were included. The mean MME administered was 40.84 (SD 30.0) and was inversely associated with ISS (R = -.05; P = .40). Patients treated by a high-intensity ED prescriber had approximately three times higher odds of receiving over 40.84 MME (OR 2.8, 95% CI 1.33-5.90 P = .07). For those with an ISS score less than 15, the presence of a low-intensity orthopedic resident decreased the odds of receiving over 40.84 MME from 2.25 to 1.78 in the presence of a high-intensity ED prescriber. CONCLUSION: For isolated orthopedic manipulations in the ED, involvement of a low-intensity prescribing orthopedic resident significantly decreased the quantity of opioids administered for those with lower ISS injuries, thus effectively mitigating the effect of high-intensity prescribing behavior prescriber.

Clinic friendly estimation of muscle composition: Preoperative linear segmentation shows overall survival correlated with muscle mass in patients with nonmetastatic renal cell carcinoma.

Purpose: Sarcopenia is associated with decreased survival and increased complications in patients with renal cell carcinoma. Readily identifying patients with low muscle composition that may experience worse outcomes or would benefit from preoperative intervention is of clinical interest. Traditional body composition analysis methods are resource intensive; therefore, linear segmentation with routine imaging has been proposed as a clinically practical alternative. This study assesses linear segmentation's prognostic utility in nonmetastatic renal cell carcinoma. Materials and Methods: A single institution retrospective analysis of patients that underwent nephrectomy for nonmetastatic renal cell carcinoma from 2005-2021 was conducted. Linear segmentation of the bilateral psoas/paraspinal muscles was completed on preoperative imaging. Total muscle area and total muscle index associations with overall survival were determined by multivariable analysis. Results: 532 (388 clear cell) patients were analyzed, with median (IQR) total muscle index of 28.6cm2/m2 (25.8-32.5) for women and 33.3cm2/m2 (29.1-36.9) for men. Low total muscle index was associated with decreased survival (HR=1.96, 95% CI 1.32-2.90, p<0.001). Graded increases in total muscle index were associated with better survival (HR=0.95, 95% CI 0.92-0.99, p=0.006). Conclusions: Linear segmentation, a clinically feasible technique to assess muscle composition, has prognostic utility in patients with localized renal cell carcinoma, allowing for incorporation of muscle composition analysis into clinical decision-making. Muscle mass determined by linear segmentation was associated with overall survival in patients with nonmetastatic renal cell carcinoma.

Donor sperm recipients: fertility treatments, trends, and pregnancy outcomes.

PURPOSE: To report fertility treatment use and outcomes among patients who use donor sperm for intrauterine insemination (IUI), in vitro fertilization (IVF), and reciprocal IVF (co-IVF). METHODS: This is a retrospective review of patients who used donor sperm at an urban, southeastern academic reproductive center between 2014 and 2020. RESULTS: Among the 374 patients presenting for care, 88 (23.5%) were single, 188 (50.3%) were in a same-sex female partnership, and 98 (26.2%) had a male partner with a diagnosis of male factor infertility. Most patients did not have infertility (73.2%). A total of 1106 cycles were completed, of which there were 931 IUI cycles, 146 traditional IVF cycles, and 31 co-IVF cycles. Live birth rates per cycle were 11% in IUI, 42% in IVF, and 61% in co-IVF. Of all resulting pregnancies, hypertensive disorders were most commonly experienced (18.0%), followed by preterm delivery (15.3%), neonatal complications (9.5%), gestational diabetes (4.8%), and fetal growth restriction (4.8%). Of the 198 infants born, fifteen (8.3%) required admission to the neonatal intensive care unit and three (1.7%) demised. Pregnancy and neonatal complications were more likely to occur in older patients and patients with elevated body mass index. CONCLUSION: The use of donor sperm for fertility treatment is increasing. These data show reassuring live birth rates; however, they also highlight the risks of subsequent pregnancy complications. With the expansion of fertility treatment options for patients, these data assist provider counseling of patients regarding anticipated cycle success rates and possible pregnancy complications.

From Self-efficacy to Imposter Syndrome: The Intrapersonal Traits of Surgeons.

BACKGROUND: Demographic differences among surgical trainees regarding intrapersonal traits, such as imposter syndrome and assertiveness, have become widely acknowledged. However, many of these characteristics have not been examined in tandem, nor among both trainees and surgeons in practice. This study aimed to address these knowledge gaps. METHODS: This was an anonymous, voluntary survey study comprised of validated measures of (1) self-efficacy, (2) imposter syndrome, (3) assertiveness, (4) perfectionism, and (5) self-rated likeability. A multimodal recruitment strategy was used and surgeons across all subspecialties were eligible for inclusion. RESULTS: A total of 296 participants were included, with 54% identifying as female (n = 161) and 72% between the ages of 25 and 40 years of age (n = 212). Imposter syndrome, assertiveness, and perfectionism scales were normally distributed; self-efficacy and self-rated likeability scales demonstrated slight negative skew. Self-identified male sex was associated with less imposter syndrome (P < 0.001) and perfectionism (P = 0.035) and higher assertiveness (P < 0.001). Imposter syndrome was less common among older age groups (P = 0.001). CONCLUSIONS: Surgeons are a self-efficacious group of perfectionists with widespread variability in imposter syndrome and assertiveness. Female sex and younger age were associated with more imposter syndrome and less assertiveness, highlighting an opportunity for early career coaching.

Organ-Space Surgical Site Infections: Consequences and Prediction Using ACS-NSQIP.

BACKGROUND: The incidence of organ-space surgical site infections (OSIs) across the US has not decreased to the same extent as superficial and deep surgical site infections (SSIs). This study aimed to highlight the consequences and create a predictive model of OSIs using 2019 NSQIP data. MATERIALS AND METHODS: The primary data source was the ACS NSQIP 2019 Participant Use Targeted File (PUF). Chi-squared and independent t-tests evaluated the association of OSIs and other postoperative complications. Variables of interest for our predictive model included 10 surgery types, 10 relevant preoperative laboratory values, and 26 other variables including demographics and comorbidities. A stepwise logistic regression model fit with OSIs as the outcome was used to calculate the predicted ROC and c-index. RESULTS: A total of 1,076,441 cases submitted from 719 NSQIP-participating sites were included in our analysis, comprised of 16,751 (1.6%) OSIs with a median of 10 days (IQR: 11 days) between surgery and the development of an OSI. Forty-two variables were included in our final multivariable analysis. Esophageal and pancreatic surgeries yielded an approximate 4- and 6-fold higher increase in the odds of OSI, respectively (P < .001). ROC analysis yielded a c-index statistic of 0.846 (Figure 1). Associated consequences of OSIs included hospital readmission (OR = 20.74, 95% CI: 20.094-21.412, p < .001), sepsis (OR = 35.084; 95%CI: 33.75-36.47, p < .001) and higher probabilities of mortality (34% vs. 0.8%, p < .001) and morbidity (16% vs. 5.8%, p < .001). DISCUSSION: OSIs have extensive consequences and may be predictable. These types of infections are multifactorial and require quality surveillance distinct from other SSIs.

Integration of Life Care Specialists Into Orthopaedic Trauma Care to Improve Postoperative Outcomes: A Pilot Study.

BACKGROUND: AIM: This pilot study assessed the feasibility and impact of integrating a Life Care Specialist (LCS) into orthopaedic trauma care. DESIGN: This was a prospective feasibility single group pilot study at a level 1 trauma center. METHOD: The LCS is a paraprofessional behavior-based "pain coach" and delivered patient-centered opioid safety education, trained participants on nonpharmacologic pain management approaches, conducted opioid risk assessments, and coordinated care. Numeric Rating Scale pain scores were assessed on admission, at discharge, and at 2-week follow-up. Daily morphine milligram equivalents (MME) during hospitalization, opioid medication use at 2-weeks, and patient satisfaction were recorded. T test compared mean morphine milligram equivalents (MME) to historical orthopaedic trauma patient population's mean dosage at discharge from the study site. Generalized linear models assessed pain scores over time. RESULTS: Twenty-two percent of 121 total participants met criteria for moderate to severe risk of opioid misuse at initial hospitalization. On average, 2.8 LCS pain management interventions were utilized, most frequently progressive muscle relaxation (80%) and sound therapy (48%). Mean inpatient MME/day was 40.5, which was significantly lower than mean historical MME/day of 49.7 (p < .001). Pain scores improved over time from admission to 2-weeks postoperatively (p < .001). Nearly all participants agreed that the LCS was helpful in managing pain (99%). CONCLUSIONS: The findings indicate feasibility to integrate LCS into orthopaedic trauma care, evident by participant engagement and satisfaction, and that LCS serve as valuable resources to assist with pain management and opioid education.

Segmentation and Linear Measurement for Body Composition Analysis using Slice-O-Matic and Horos.

Body composition is associated with risk of disease progression and treatment complications in a variety of conditions. Therefore, quantification of skeletal muscle mass and adipose tissues on Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI) may inform surgery risk evaluation and disease prognosis. This article describes two quantification methods originally described by Mourtzakis et al. and Avrutin et al.: tissue segmentation and linear measurement of skeletal muscle. Patients' cross-sectional image at the midpoint of the third lumbar vertebra was obtained for both measurements. For segmentation, the images were imported into Slice-O-Matic and colored for skeletal muscle, intramuscular adipose tissue, visceral adipose tissue, and subcutaneous adipose tissue. Then, surface areas of each tissue type were calculated using the tag surface area function. For linear measurements, the height and width of bilateral psoas and paraspinal muscles at the level of the third lumbar vertebra are measured and the calculation using these four values yield the estimated skeletal muscle mass. Segmentation analysis provides quantitative, comprehensive information about the patients' body composition, which can then be correlated with disease progression. However, the process is more time-consuming and requires specialized training. Linear measurements are an efficient and clinic-friendly tool for quick preoperative evaluation. However, linear measurements do not provide information on adipose tissue composition. Nonetheless, these methods have wide applications in a variety of diseases to predict surgical outcomes, risk of disease progression and inform treatment options for patients.

Evaluating the impact of stay-at-home orders on the time to reach the peak burden of Covid-19 cases and deaths: does timing matter?

BACKGROUND: The economic, psychological, and social impact of pandemics and social distancing measures prompt the urgent need to determine the efficacy of non-pharmaceutical interventions (NPIs), especially those considered most stringent such as stay-at-home and self-isolation mandates. This study focuses specifically on the impact of stay-at-home orders, both nationally and internationally, on the control of COVID-19. METHODS: We conducted an observational analysis from April to May 2020 and included both countries and US states with known stay-at-home orders. Our primary exposure was the time between the date of the first reported case of COVID-19 to an implemented stay-at-home mandate for each region. Our primary outcomes were the time from the first reported case to the highest number of daily cases and daily deaths. We conducted linear regression analyses, controlling for the case rate of the outbreak in each respective region. RESULTS: For countries and US states, a longer period of time between the first reported case and stay-at-home mandates was associated with a longer time to reach both the peak daily case and death counts. The largest effect was among regions classified as the latest 10% to implement a mandate, which in the US, predicted an extra 35.3 days (95% CI: 18.2, 52.5) to the peak number of cases, and 38.3 days (95% CI: 23.6, 53.0) to the peak number of deaths. CONCLUSIONS: Our study supports the association between the timing of stay-at-home orders and the time to peak case and death counts for both countries and US states. Regions in which mandates were implemented late experienced a prolonged duration to reaching both peak daily case and death counts.

HIV Testing Preferences Among MSM Members of an LGBT Community Organization in Los Angeles.

Lack of regular HIV testing puts African American, Asian, and Latino men who have sex with men (MSM) at high risk for HIV infection. Rapid self-testing may be an effective option for these men. We explored acceptability, preferences, and usability of HIV self-test kits with MSM of color using semi-structured focus groups to discuss HIV testing history, reasons for testing, and self-testing preferences. Participants (n = 21) lived in Los Angeles, identified as MSM of color, and were 18-35 years of age. Discussions were audio-recorded, transcribed, and analyzed using grounded theory. Participants expressed needs for (a) accessibility, (b) privacy, (c) local support, and (d) access to testing professionals. Self-testing for HIV infection may be an effective method for high-risk MSM. Effective self-testing programs need to consider accessibility, confidentiality, and support to increase routine testing. Community-based organizations have an opportunity to increase HIV testing for MSM of color.

Lost opportunity to save newborn lives: variable national antenatal screening policies for Neisseria gonorrhoeae and Chlamydia trachomatis.

Unfavorable pregnancy outcomes caused by Chlamydia trachomatis or Neisseria gonorrhoeae infection are well known. The first step in addressing antenatal C. trachomatis and N. gonorrhoeae infection is a national policy to screen all pregnant women for C. trachomatis and N. gonorrhoeae, regardless of symptoms. The aim of this study was to inform policy makers on the presence of antenatal screening recommendations for C. trachomatis and N. gonorrhoeae infection. We conducted a three-part study from June 2015 to February 2016. We analyzed English and French language information online on Ministry of Health websites regarding C. trachomatis and N. gonorrhoeae antenatal screening. We referenced both primary official country and regional policy documents. We contacted the Ministry of Health directly if the information on the national antenatal screening was outdated or unavailable. In parallel, we sent a survey to the regional representative from the World Health Organization to help collect country-level data. Fourteen countries have current policies for antenatal screening of C. trachomatis and/or N. gonorrhoeae infection: Australia, the Bahamas, Bulgaria, Canada, Estonia, Japan, Germany, Latvia, New Zealand, Democratic People's Republic of Korea, Romania, Sweden, the United Kingdom, and the United States. Australia, New Zealand, and Latvia and the United States restricted antenatal screening to women ≤25 years old and those of higher risk. Several countries responded that they had policies to treat pregnant women with symptoms. This is the currently recommended WHO guideline but is not the same as universal screening. North Korea had policies in place which were not implemented due to lack of personnel and/or supplies. National level policies to support routine screening for C. trachomatis and N. gonorrhoeae infection to prevent adverse pregnancy and newborn outcomes are uncommon.
