Study Design.
Retrospective cohort study.

Objective.
To evaluate the impact of admission status on patient outcomes and healthcare costs in anterior cervical discectomy and fusion (ACDF).

Summary of Background Data.
Undergoing ACDF non-electively has been associated with higher patient comorbidity burdens. However, the impact of non-elective status on the total cost of hospital stay has yet to be quantified.

Methods.
Patients undergoing ACDF at a single institution were placed into elective or non-elective cohorts. Propensity score-matching analysis in a 5:1 ratio controlling for insurance type and comorbidities was used to minimize selection bias. Demographics were compared by univariate analysis. Cost of care, length of stay (LOS), and clinical outcomes were compared between groups using multivariable linear and logistic regression with elective patients as reference cohort. All analyses controlled for sex, preoperative diagnosis, elixhauser comorbidity index (ECI), age, length of surgery, number of segments fused, and insurance type.

Results.
Of 708 patients in the final ACDF cohort, 590 underwent an elective procedure and 118 underwent a non-elective procedure. The non-elective group was significantly younger (53.7 vs. 49.5 yr; P = 0.0007). Cohorts had similar proportions of private versus public health insurance, although elective had higher rates of commercial insurance (39.22% vs. 15.25%; P < 0.0001) and non-elective had higher rates of managed care (32.77% vs. 56.78%; P < 0.0001). Operation duration was significantly longer in non-elective patients (158 vs. 177 minutes; P = 0.01). Adjusted analysis also demonstrated that admission status independently affected cost (+$6877, 95% confidence interval [CI]: $4906–$8848; P < 0.0001) and LOS (+4.9 days, 95% CI: 3.9–6.0; P < 0.0001) for the non-elective cohort. The non-elective cohort was significantly more likely to return to the operating room (OR: 3.39; 95% CI: 1.37–8.36, P = 0.0008) and experience non-home discharge (OR: 10.95; 95% CI: 5.00–24.02, P < 0.0001).

Conclusion.
Patients undergoing ACDF non-electively had higher cost of care and longer LOS, as well as higher rates of postoperative adverse outcomes.

Adult-Onset Still’s Disease Presenting as Macrophage-Activation Syndrome With Critical Illness in the Third Trimester of Pregnancy: A Case Report
Authors: Peters Andrew T. , Prickett Michelle H. 
Published: May 2021

BACKGROUND:
We report a case of a young woman with adult-onset Still’s disease presenting as macrophage-activation syndrome complicated by shock and respiratory failure during the third trimester of pregnancy.

CASE SUMMARY:
A previously healthy 26-year-old woman at 35 weeks of gestation presented with 1 week of constitutional symptoms and was found to be febrile, tachycardic, and hypotensive. She delivered a healthy neonate by cesarean section. Following delivery, she had worsening hypotension and fevers despite fluid resuscitation and antibiotics, and developed progressive hypoxemia requiring up to 60% Fio
2, with bilateral upper-lobe predominant opacities on chest CT. She also had laboratory derangements including anemia, thrombocytopenia, low fibrinogen, elevated ferritin, and abnormal liver chemistries. After extensive testing to exclude infections, hemolysis, and other pertinent disorders, the development of polyarthralgias and a characteristic rash fulfilled criteria for adult-onset Still’s disease complicated by macrophage-activation syndrome. Her condition improved with immunosuppressive therapy.

CONCLUSION:
To our knowledge, this is the first report of new-onset adult-onset Still’s disease during the third trimester of pregnancy, which presented as macrophage-activation syndrome. In the context of late pregnancy, macrophage-activation syndrome can mimic or raise concern for hemolysis, elevated liver enzymes, and low platelet syndrome and other peripartum disorders. Furthermore, the characteristic articular symptoms of adult-onset Still’s disease may be mild and/or delayed, and pulmonary involvement with severe hypoxemia can occur. Clinicians should consider this diagnosis when evaluating a pregnant patient with unexplained fever and multiorgan dysfunction.
Reporting and grading of complications after mid-urethral sling surgeries: Could the “Clavien-Dindo Classification” be adopted?
Authors: El-Hefnawy Ahmed S. , Wadie Bassem S. 
Published: May 2021

Abstract

Background:
To construct a modified model for reporting and grading of postoperative complications after the mid-urethral sling (MUS) procedure based on the Clavien-Dindo classification. In addition, complications of three different types of MUS were compared.

Materials and methods:
A PubMed search for postoperative complication after MUS was carried out for the period between January 1990 and July 2018. Reported complications were stratified in a plate form designed in accordance with grades of the Clavien-Dindo classification. Then, the proposed model was applied on reported complications in 160 females who underwent three different procedures of MUS (transvaginal tape [TVT], transobturator tape [TOT], and autologous fascial sling) with a minimum follow-up of 24 months.

Results:
The mean ± SD age at time of surgery was 46 ± 7 years. TVT was carried out in 75 (47%) patients, TOT in 40 (25%), and fascial sling in 45 (28%). The total number of complications was 62 in 43 (26.8%) patients. The vast majority of complications were Grade I and Grade II 19 (12%) and 21 (13%) out of 160 patients, respectively. Transient postoperative voiding difficulty (Grade II) and de novo urgency (Grade II) were the most prevalent complications in the fascial sling method (15.4% for each), whereas transient thigh pain (Grade II) was the most frequently reported complication after TOT (10%). Life-threatening vascular injury (Grade IV-a) was a serious complication in TVT cases.

Conclusions:
Postoperative complications of the MUS could be graded according to Clavien's classification. The vast majority of complications were Graded I or II. TVT can cause serious life-threatening complications.

Published: May 2021

Abstract

Background:
Nephron sparing surgery is a well-established surgical procedure for patients with small/bilateral renal masses. During the procedure, hilar control can be achieved by using bulldog clamps individually on the renal vessels, the renal artery alone without clamping the vein, or a laparoscopic Satinsky clamp for en bloc hilar clamping. In our series, we described the outcome of laparoscopic nephron sparing surgery using a Satinsky clamp for hilar control.

Materials and methods:
All eligible cases with confirmed diagnosis of a renal mass were advised of nephron sparing surgery. The short-term outcomes were evaluated by warm ischemia time (using a Satinsky clamp especially when CT renal angiography was not available), average blood loss, and length of postoperative hospital stay. The oncological outcome was evaluated by noting the surgical margins of histopathological specimen, local recurrence, and distant metastasis.

Results:
Of 30 cases 20 were male. The mean age was 54.25 years. On preoperative evaluation, 24 cases were T1a stage and the rest were 6 T1b stage. Four tumors were located in the upper pole, 4 in the posterior midpole, and 22 in the lower pole. Twenty-six patients had a low complexity score on RENAL scoring (ie, 4–6) and 4 patients a medium complexity score (ie, 7–9). Three patients were converted to open partial nephrectomy because of technical difficulty in intracorporeal suturing and difficulty in achieving hemostasis. Among these 3 patients, 2 patients had posterior base tumors and 1 had a lower polar tumor. Average blood loss was 350 ml, warm ischemia time was 28.46 minutes, and postoperative stay was 4.55 days. Of 30 specimens for histopathology, 23 (76%) were clear cell renal cell carcinoma (RCC), 4 (13%) were papillary RCC, 1 (3.3%) was chromophobe RCC, whereas 2 (6.6%) were benign (oncocytoma). Margins were free of tumors in all the patients with no recurrence in 2 years of follow-up.

Conclusion:
Laparoscopic partial nephrectomy by using a Satinsky clamp as a tool for en bloc hilar clamping in the proper axis at the hilum takes care of multiple vessels irrespective of size and number, particularly when renal angiography is not available. This technique of en bloc hilar clamping is quite useful especially in developing countries where robotic facilities are not available. The Satinsky clamp decreases blood loss and intraoperative time.
Self-development Tools Utilized by Plastic Surgeons: A Survey of ASPS Members
Authors: Gonzalez Santiago R. , Blumenauer Brian J. , Yuen James C. , Golinko Michael S. 
Published: May 2021

Background:
The plastic surgery literature is devoid of research on the topic of professional development tools that may be used to enhance performance as a plastic surgeon. After an extensive review of the medical literature, we selected the most frequently referenced professional development tools utilized by plastic surgeons, which included the following: goal setting, positive visualization, scheduled practice, critically analyzing mistakes, professional development conferences, involvement in sports, motivational videos, podcasts & audiobooks, daily morning routines, self-development books, and advice from mentors.

Methods:
A 10-question survey was sent to 2542 members of the American Society of Plastic Surgeons (ASPS). The algorithm used to select ASPS members to survey was based on member demographics that would best reflect the views of the entire active society membership. Responses were compared based on demographic factors such as type of practice, gender, and age.

Results:
A total of 286/2542 (11.25%) ASPS members participated in the survey. Analyzing mistakes (96.3%), goal setting (88.51%), and advice from mentors (85.2%) were most commonly attributed to self-development. Respondents in an academic practice favored conferences and advice from mentors. Participants in a solo practice favored self-help books and morning routines. No statistical differences were observed based on training background.

Conclusions:
ASPS members attribute their professional development to setting measurable goals, carefully analyzing surgical mistakes, and guidance from mentors. This information opens the door for continued analysis of professional development within plastic surgery as well as supplement training practices at the resident and post-graduate level.

Authors: Carreira Ana Rita , Rodrigues-Barros Sandra , Moraes Filipe , Loureiro Tomás , Machado Inês , Campos Paul , Nobre Cardoso João , Campos Nuno 
Published: May 2021

Purpose:
Our aim was to assess ocular surface and tear film stability and corneal epithelial thickness (CET) in patients with Graves disease (GD) with and without Graves orbitopathy (GO).

Methods:
This study included healthy age-matched controls and patients with GD. Symptoms (Ocular Surface Disease Index questionnaire) and signs (schirmer test and tear breakup time test) of dry eye disease were determined, according to the International Dry Eye Workshop II criteria of DED. CET map was also assessed.

Results:
Twenty-four eyes were included in the control group, with a mean age of 41.00 ± 13.65 years, and 34 in the GD group, 18 with GO and 16 without GO, with a mean age of 44.44 ± 13.95 and 45.75 ± 10.59 years, respectively. All patients with GO had inactive disease (mean clinical activity score: 1.33 ± 0.69). Patients with GD had higher proportion of clinical diagnosis of dry eye disease (GO vs. GD without GO vs. controls: 77.77% vs. 75.00% vs. 4.17%), with higher Ocular Surface Disease Index (GO vs. GD without GO vs. controls: 15.44 vs. 15.06 vs. 9.88) and lower tear breakup time test (GO vs. GD without GO vs. controls: 6.33 s vs. 7.25 s vs. 11.63 s). Superior CET was lower in patients with GD (P < 0.05). No differences were found between patients with and without GO (P > 0.05).

Conclusions:
GD negatively influenced ocular surface and CET, with a higher level of eye dryness and corneal thinning regardless of GO status, suggesting that subclinical chronic inflammation may play a role in the pathogenesis of tear film and ocular surface stability.
Late Corneal Stromal Deposits After COVID-19
Authors: Pareja-Ríos Alicia , Bonaque-González Sergio 
Published: May 2021

Abstract:
We present 2 cases of striking stromal corneal infiltrates months after COVID-19 infection. While we cannot prove that these infiltrates are caused by or directly related to COVID-19, we did not find any other plausible cause that could explain these ophthalmic signs. In these cases, the ongoing process was detected in relatively early stages due to scheduled visits with patients and responded positively to prednisolone acetate 1% ophthalmic suspension. However, we do not know the response to treatment in more advanced cases.
Clinical relevance of attentional biases in pediatric chronic pain: an eye-tracking study

Published: May 2021

Abstract
Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.
Physical Activity Participation After a 16-Week Supervised Workplace Exercise RCT With a 15-Month Follow-Up
Authors: Hunter Jayden R. , Gordon Brett A. , Huynh Minh , Benson Amanda C. 
Published: May 2021

Objective:
To investigate the effects of exercise supervision on short- and longer-term moderate-vigorous physical activity (MVPA) participation.

Methods:
Fifty-six Australian university employees completed a 16-week moderate-to-high intensity aerobic and resistance exercise intervention, and the international physical activity questionnaire (IPAQ) 15 months later. Participants received either personal (SUP; n = 21) or non-personal (NPS; n = 19) exercise supervision at an onsite facility or exercised offsite with no supervision (CON; n = 16).

Results:
A linear mixed model identified a significant group × time interaction effect for MVPA, with increases at 15-month follow-up for CON only. Pooled data suggested more participants completed ≥500 MET-minutes of weekly MVPA at 16 weeks (66%) and 15-month follow-up (68%) compared to baseline (54%).

Conclusions:
A comprehensive health and fitness assessment and individually tailored exercise without personal supervision may promote ongoing MVPA.
The Correlation of Clinical Corticosteroid Responsiveness With Expression of IL-6 in Peripheral Blood Immune Cells (PBMC) in Patients With Autoimmune Inner Ear Disease (AIED)
Authors: Gorthey Scott W. , Pathak Shresh , Vambutas Andrea 
Published: May 2021

Hypothesis:
Autoimmune inner ear disease (AIED) patients will differentially express interleukin (IL)-6 based on corticosteroid responsiveness.

Background:
AIED is characterized by periods of acute sensorineural hearing loss (SNHL). In a majority of patients corticosteroid responsiveness is lost over time. The mechanisms that control corticosteroid responsiveness have not been fully elucidated.

Methods:
Thirty-five AIED patients and 13 age-matched control subjects were enrolled in this study. Steroid responsive (n = 15) and steroid nonresponsive AIED patients (n = 20) were characterized based on audiometry before and after treatment for acute SNHL. Plasma and peripheral blood mononuclear cells (PBMC) were obtained at the time of acute SNHL to quantify plasma IL-6, soluble IL-6 receptor (sIL-6R), and C-C Motif Chemokine Ligand 3 (CCL3). PBMCs were stimulated with dexamethasone and release of soluble IL-6, sIL-6R, and CCL3 protein into conditioned supernatants was measured. Plasma IL-6 was also correlated to serum c-reactive protein (CRP), cardiac CRP, erythrocyte sedimentation rate.

Results:
Statistically significant differences were observed in the plasma IL-6 between AIED patients and controls (2.37 versus 2.03 pg/ml, p < 0.01), plasma IL-6, and CCL3 between responders and nonresponders (0.136 versus 3.84 pg/ml, p < 0.005; 30.5 versus 32.4, p < 0.05) and released IL-6 from dexamethasone stimulated PBMC in AIED patients compared with controls (0.54 versus 1.12 pg/ml, p < 0.001). There was a correlation between plasma IL-6 levels of AIED patients to both serum CRP and cardiac CRP (R2 = 0.83, R2 = 0.88).

Conclusions:
We observed AIED patients, specifically nonresponders expressed greater levels of IL-6. Elevated IL-6 levels in AIED patients correlated with CRP levels, providing a commonly available laboratory test that may aid in rapid clinical decision-making in these patients.
An Open-label, Multicenter Study to Assess the Efficacy and Safety of a Novel Probiotic Blend in Patients With Functional Gastrointestinal Symptoms
Authors: Harris Lucinda A. , Cash Brooks D. , Moftah Karim , Franklin Howard 
Published: May 2021

Goal:A novel 5-strain (Bl-04, Bi-07, HN019, NCFM, and Lpc-37) probiotic blend was developed and its safety and efficacy were evaluated in patients with functional gastrointestinal (GI) symptoms.Background:These strains administered together have not previously been investigated.Study:Patients aged 18 to 75 years with functional GI symptoms were eligible for inclusion in a single-arm, open-label, multicenter study (NCT04155801). An oral capsule containing the novel probiotic blend was administered once daily for 30 days. The primary efficacy endpoint was patient-reported improvement in overall GI well-being at day 30. Secondary efficacy endpoints included changes in GI symptoms assessed using the GI Health Symptom Questionnaire. Incidence of treatment-emergent adverse events was recorded at all visits.Results:Of 188 enrolled patients, 72.3% were female and mean (SD) age was 44.1 (13.4) years. At day 30, 85.1% of patients achieved the primary endpoint, a positive response signifying improvement in overall GI well-being. Improvements from baseline were reported at day 30 in diarrhea frequency (baseline frequency≥3 to 4 d/wk) and severity (baseline severity≥5/10) for 75.8% and 87.3% of patients, respectively. Over the same time period, constipation frequency (baseline frequency≥3 to 4 d/wk) and severity (baseline severity≥5/10) improved in 73.6% and 80.4% of patients, respectively. Most patients reported improvements at day 30 in frequency and severity of straining, urgency, abdominal pain/discomfort, bloating, and distention. Improvements reported at day 30 were generally observable at day 14. No safety signals were identified.Conclusion:A novel 5-strain probiotic blend improved functional GI symptoms and was safe.
Gut microbiome, parathyroid hormone, and bone
Authors: Kermgard Elizabeth , Chawla Nadine Khouzam , Wesseling-Perry Katherine 
Published: May 2021

Purpose of review
Microorganisms in the gut (the ‘microbiome’) and the metabolites they produce (the ‘metabolome’) regulate bone mass through interactions between parathyroid hormone (PTH), the immune system, and bone. This review summarizes these data and details how this physiology may relate to CKD-mediated bone disease.

Recent findings
The actions of PTH on bone require microbial metabolite activation of immune cells. Butyrate is necessary for CD4+ T-cell differentiation, T-reg cell expansion and CD8+ T-cell secretion of the bone-forming factor Wnt10b ligand. By contrast, mice colonized with segmented filamentous bacteria exhibit an expansion of gut Th17 cells and continuous PTH infusion increases the migration of Th17 cells to the bone marrow, contributing to bone resorption. In the context of CKD, a modified diet, frequent antibiotic therapy, altered intestinal mobility, and exposure to multiple medications together contribute to dysbiosis; the implications for an altered microbiome and metabolome on the pathogenesis of renal osteodystrophy and its treatment have not been explored.

Summary
As dysregulated interactions between PTH and bone ('skeletal resistance’) characterize CKD, the time is ripe for detailed, mechanistic studies into the role that gut metabolites may play in the pathogenesis of CKD-mediated bone disease.
Coronavirus disease 2019 and kidney injury
Authors: Punj Shweta , Eng Eudora , Shetty Aneesha A. 
Published: May 2021

Purpose of review
In this paper, we seek to review coronavirus disease 2019 (COVID-19) associated kidney injury with a focus on what is known about pathophysiology.

Recent findings
Kidney injury is a common complication of SARS-CoV-2 infection and is associated with increased morbidity and mortality. Acute tubular necrosis and glomerular injury are two common findings. Direct viral effect, endothelial dysfunction, and podocyte and tubular epithelial injury have been described. COVID-19-related glomerular injury may also be associated with high-risk APOL1 genotype.

Summary
Data on COVID-19 renal involvement have suggested novel mechanisms of kidney injury that need to be further elucidated. More data are needed on renal involvement in milder disease, renal-specific therapeutic interventions, and long-term sequelae.
