Retrospective cohort study.
To investigate correlations between preoperative supine imaging and postoperative alignment.
A retrospective review was conducted of a single-institution database of patients with adult spinal deformity (ASD). Patients were stratified by fusion location in the lumbar or thoracic spine. Outcomes of interest were postoperative lumbar lordosis (LL) and thoracic kyphosis (TK). Sagittal alignment parameters were compared and correlation analyses were performed. Multilinear stepwise regression was conducted to identify independent predictors of postoperative LL or TK. Regression analyses were repeated within the lumbar and thoracic fusion cohorts.
A total of 99 patients were included (mean age 63.2 years, 83.1% female, mean body mass index 27.3 kg/m
). Scoliosis Research Society classification demonstrated moderate to severe sagittal and/or coronal deformity (pelvic tile modifier, 18.2% ++; sagittal vertical axis, 27.3% ++, pelvic incidence minus lumbar lordosis mismatch, 29.3% ++, SRS type, 29.3% N type curve and 68.7% L or D type curve). A total of 73 patients (73.7%) underwent lumbar fusion and 50 (50.5%) underwent thoracic fusion. Correlation analyses demonstrated a significant association between pre- and postoperative LL and TK. Multilinear regression demonstrated that LL supine and pelvic incidence were significant predictors of postoperative LL (
= 0.568,
< .001). LL supine, TK supine, and age were significant predictors of postoperative TK (
= 0.490,
< .001).
Preoperative supine films are superior to standing in predicting postoperative alignment at 1-year follow-up. Anticipation of undesired alignment changes through supine imaging may be useful in mitigating the risk of iatrogenic malalignment.

The overall severity of cardiac disease secondary to acute SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) infection in children appears to be much lower when compared with adults. However, the newly described multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019 (COVID-19) has been associated with cardiac complications.
We reviewed the clinical course and cardiac testing results in pediatric patients hospitalized with MIS-C at 2 large hospital systems in the New York City metropolitan area over a 3-month period.
Of the 33 patients (median age 2.8 years) in the study cohort, 24 (73%) had at least one abnormality in cardiac testing abnormal electrocardiogram (48%), elevated brain natriuretic peptide (43%), abnormal echocardiogram (30%), and/or elevated troponin (21%). Electrocardiogram and echocardiogram abnormalities all resolved by the 2-week outpatient follow-up cardiology visit.
While 73% of pediatric patients with MIS-C had evidence of abnormal cardiac testing on hospital admission in our study, all cardiac testing was normal by outpatient hospital discharge follow-up. Cardiac screening tests should be performed in all patients diagnosed with MIS-C given the high rate of abnormal cardiac findings in our study cohort.

Cardiac screening tests should be performed in all patients diagnosed with MIS-C given the high rate of abnormal cardiac findings in our study cohort.The current research developed ultra-brief (SSOSH-3) and revised (SSOSH-7) versions of the Self-Stigma of Seeking Help scale. Item response theory was used to examine the amount of information each item provided across the latent variable scale and test whether items functioned differently across women and men. In a sample of 857 community adults, results supported removal of three reverse-scored items to create the SSOSH-7. The three most informative items were retained to create the SSOSH-3. Differential item functioning testing supported the use of both versions across women and men. Results replicated in an undergraduate student sample (n = 661). Curzerene In both samples, the SSOSH-3 (αs = .82-.87) and SSOSH-7 (αs = .87-.89) demonstrated evidence of internal consistency. The SSOSH-3 (rs ≥ .89) and SSOSH-7 (rs ≥ .97) were highly correlated with the original SSOSH across samples and demonstrated significant correlations with help-seeking constructs and in similar magnitude to the original SSOSH.
The objective of this study was to compare the effects of hyperosmolar sodium (Na
), lithium (Li
) and potassium (K
) on catabolic and inflammatory osteoarthritis (OA) markers and sulfated glycosaminoglycan (sGAG) loss in TNF-α-stimulated cartilage explants.
Explants from bovine stifle joints were stimulated with TNF-α for 1 day to induce cartilage degradation followed by supplementation with 50 mM potassium chloride (KCl), 50 mM lithium chloride (LiCl), 50 mM sodium chloride (NaCl), or 100 nM dexamethasone for an additional 6 days. We assessed the effect of TNF-α stimulation and hyperosmolar ionic treatment on sGAG loss and expression of OA-associated proteins ADAMTS-5, COX-2, MMP-1, MMP-13, and VEGF.
TNF-α treatment increased sGAG loss (
< 0.001) and expression of COX-2 (
= 0.018), MMP-13 (
< 0.001), and VEGF (
= 0.017) relative to unstimulated controls. Relative to activated controls, LiCl and dexamethasone treatment attenuated sGAG loss (
= 0.008 and
= 0.042, respectively) and expression of MMP-13 (
= 0.005 and
= 0.036, respectively). In contrast, KCl treatment exacerbated sGAG loss (
= 0.032) and MMP-1 protein expression (
= 0.010). NaCl treatment, however, did not alter sGAG loss or expression of OA-related proteins. Comparing LiCl and KCl treatment shows a potent reduction (
< 0.05) in catabolic and inflammatory mediators following LiCl treatment.
These results suggest that these ionic species elicit varying responses in TNF-α-stimulated explants. Cumulatively, these findings support additional studies of hyperosmolar ionic solutions for potential development of novel intraarticular injections targeting OA.
