ABSTRACT

BACKGROUND AND OBJECTIVES: Pediatric hospitalizations are costly, stressful events for families. Many caregivers, especially those with lower incomes, struggle to afford food while their child is hospitalized. We sought to decrease the mean percentage of caregivers of Medicaid-insured and uninsured children who reported being hungry during their child’s hospitalization from 86% to <24%.

METHODS: Our quality improvement efforts took place on a 41-bed inpatient unit at our large, urban academic hospital. Our multidisciplinary team included physicians, nurses, social workers, and food services leadership. Our primary outcome measure was caregiver-reported hunger; we asked caregivers near to the time of discharge if they experienced hunger during their child’s hospitalization. Plan-do-study-act cycles addressed key drivers: awareness of how to obtain food, safe environment for families to seek help, and access to affordable food. An annotated statistical process control chart tracked our outcome over time. Data collection was interrupted because of the COVID-19 pandemic; we used that time to advocate for hospital-funded support for optimal and sustainable changes to caregiver meal access.

RESULTS: We decreased caregiver hunger from 86% to 15.5%. A temporary test of change, 2 meal vouchers per caregiver per day, resulted in a special cause decrease in the percentage of caregivers reporting hunger. Permanent hospital funding was secured to provide cards to purchase 2 meals per caregiver per hospital day, resulting in a sustained decrease in rates of caregiver hunger.

CONCLUSIONS: We decreased caregivers’ hunger during their child’s hospitalization. Through a data-driven quality improvement effort, we implemented a sustainable change allowing families to access enough food.

ABSTRACT

OBJECTIVE: Using a fibula autograft (FA) to reconstruct defects after en bloc resection of giant cell tumor of bone (GCTB) in the distal radius is classic but has high complication rates. We describe a novel reconstruction method employing the cooperative application of LARS® and a 3D-printed prosthesis (L-P) and investigate whether it improves postoperative outcomes.

METHODS: From April 2015 to August 2022, 14 patients who underwent the cooperative L-P reconstruction method after en bloc resection of distal radial GCTBs and 31 patients who received FA reconstruction were enrolled as two retrospective cohorts in this comparative study. The properties of the implants and critical surgical techniques were elaborated in the L-P group. Preoperative function, intraoperative data, and postoperative clinical, functional, and radiographic outcomes of all patients were recorded and compared between the two groups. The grip strength and range of wrist motion, including extension, flexion, radial deviation, and ulnar deviation, were measured. The Mayo modified wrist and Musculoskeletal Tumor Society scores were chosen to assess wrist function and surgical functional outcomes, respectively. Kaplan-Meier curves were generated to analyze the significant differences in complication rates and implant survival between the two groups.

RESULTS: In both groups, all 45 patients underwent the operation without complication with similar average osteotomy lengths and bleeding volumes, while a shorter operative duration was achieved in the L-P group (201.43 ± 22.87 min vs. 230.16 ± 51.44 min, P = 0.015). At a mean follow-up of 40.42 ± 18.43 months (range, 14-72 months), both reconstruction methods effectively ameliorated postoperative function. Patients who received L-P showed higher postoperative modified Mayo wrist scores (81.43 ± 5.49 vs. 71.13 ± 16.10, P = 0.003), Musculoskeletal Tumor Society scores (27.64 ± 1.34 vs. 25.06 ± 2.95, P = 0.004), and grip strength on the normal side (68.71% ± 8.00% vs. 57.81% ± 12.31%, P = 0.005) than the FA group. Better wrist extension (63.21° ± 8.99° vs. 45.32° ± 14.53°, P < 0.001) and flexion (45.36° ± 7.90° vs. 30.48° ± 12.07°, P < 0.001) were also observed in the L-P group. The complication rate was significantly higher in the FA group (29/31, 93.55%) than in the L-P group (1/14 7.14%, P < 0.001). The L-P group showed higher implant survival than the FA group, but the difference was not statistically significant.

CONCLUSION: The cooperative application of LARS® and 3D-printed prostheses is an effective modality for reconstructing musculoskeletal defects after en bloc resection of distal radial GCTBs, which can improve functional outcomes, diminish complication rates, and promote wrist joint stability and motion.

ABSTRACT

OBJECTIVES: Pediatric Hospital Medicine fellowship programs need to abide by Accreditation Council for Graduate Medical Education requirements regarding communication and supervision. Effective communication is critical for safe patient care, yet no prior research has explored optimal communication practices between residents, fellows, and attending hospitalists. Our objective is to explore communication preferences among pediatric senior residents (SRs), Pediatric Hospital Medicine fellows, and hospitalists on an inpatient team during clinical decision-making.

METHODS: We conducted a cross-sectional survey study at 6 institutions nationwide. We developed 3 complementary surveys adapted from prior research, 1 for each population: 200 hospitalists, 20 fellows, and 380 SRs. The instruments included questions about communication preferences between the SR, fellow, and hospitalist during clinical scenarios. We calculated univariate descriptive statistics and examined paired differences in percent agreement using χ2 tests, accounting for clustering by institution.

RESULTS: Response rates were: 53% hospitalists; 100% fellows; 39% SRs. Communication preferences varied based on role, scenario, and time of day. For most situations, hospitalists preferred more communication with the fellow overnight and when a patient or family is upset than expressed by fellows (P < .01). Hospitalists also desired more communication between the SR and fellow for an upset patient or family than SRs (P < .01), but all respondents agreed the SR should call the fellow for adverse events. More fellows and hospitalists felt that the SR should contact the fellow before placing a consult compared with SRs (95%, 86% vs 64%).

CONCLUSIONS: Hospitalists, fellows, and SRs may have differing preferences regarding communication, impacting supervision, autonomy, and patient safety. Training programs should consider such perspectives when creating expectations and communication guidelines.

ABSTRACT

BACKGORUND: We aimed to show whether the serum level of Human Epididymitis Protein 4 increases in rats with an experimental acute pancreatitis model created by cerulein.

METHODS: This study included 24 male Sprague-Dawley rats which were randomly divided into 4 groups each containing 6 rats.

CONTROL: the group treated with saline, Group 1: pancreatitis group created with cerulein at a total dose of 80 µg/kg, Group 2: pancreatitis group created with cerulein at a total dose of 120 µg/kg, Group 3: pancreatitis group created with cerulein at a total dose of 160 µg/kg.

RESULTS: There were statistically significant differences between edema, acinar necrosis, fat necrosis, and perivascular inflammation scores among the study groups. While the degree of all histopathological findings is lowest in the control group, pancreatic parenchyma damage increases as the amount of injected cerulein increases. There was no statistically significant difference between alanine aminotransferase, aspartate aminotransferase, and Human Epididymis Protein 4 values between study groups. On the other hand, there was a statistically significant difference between amylase and lipase values. The lipase value of the control group was significantly lower than the lipase value of the second and third groups. The amylase value of the control group was significantly lower than all other groups. The highest Human Epididymis Protein 4 value was measured as 104 pmol/L in the first pancreatitis group, where the severity of pancreatitis was mild.

CONCLUSIONS: In the present study, it was concluded that the Human Epididymis Protein 4 value increased in the case of mild pancreatitis, but there is no correlation between the severity of pancreatitis and the Human Epididymis Protein 4 value.

ABSTRACT

BACKGROUND: Standardised performance assessment of image acquisition, reconstruction and processing methods is limited by the absence of images paired with ground truth reference values. To this end, we propose MRXCAT2.0 to generate synthetic data, covering healthy and pathological function, using a biophysical model. We exemplify the approach by generating cardiovascular magnetic resonance (CMR) images of healthy, infarcted, dilated and hypertrophic left-ventricular (LV) function.

METHOD: In MRXCAT2.0, the XCAT torso phantom is coupled with a statistical shape model, describing population (patho)physiological variability, and a biophysical model, providing known and detailed functional ground truth of LV morphology and function. CMR balanced steady-state free precession images are generated using MRXCAT2.0 while realistic image appearance is ensured by assigning texturized tissue properties to the phantom labels.

FINDING: Paired CMR image and ground truth data of LV function were generated with a range of LV masses (85-140 g), ejection fractions (34-51%) and peak radial and circumferential strains (0.45 to 0.95 and – 0.18 to – 0.13, respectively). These ranges cover healthy and pathological cases, including infarction, dilated and hypertrophic cardiomyopathy. The generation of the anatomy takes a few seconds and it improves on current state-of-the-art models where the pathological representation is not explicitly addressed. For the full simulation framework, the biophysical models require approximately two hours, while image generation requires a few minutes per slice.

CONCLUSION: MRXCAT2.0 offers synthesis of realistic images embedding population-based anatomical and functional variability and associated ground truth parameters to facilitate a standardized assessment of CMR acquisition, reconstruction and processing methods.

ABSTRACT

BACKGROUND: Thyroid dysfunction is among the most common immune-related adverse events (irAEs) of immune checkpoint inhibitors (ICIs) therapy. Data regarding potential predictors of the development of thyroid irAEs are still limited and sometimes conflicting.

PATIENTS AND METHODS: We assessed potential risk factors and clinical outcomes associated with the onset of thyroid irAEs in a cohort of patients with different types of cancer treated with ICIs at a single center. Clinical and biochemical data, including thyroid function tests and autoantibodies at baseline and during treatment, were collected, and the onset of thyroid irAEs was recorded. Patients with thyroid dysfunction and/or under levothyroxine therapy before starting ICI were excluded.

RESULTS: 110 patients (80 M, 30 F, aged 32-85 years; 56.4% non-small-cell lung cancer, 87% treated with anti-PD-1) with complete information were included in the study. Among them, 32 (29%) developed thyroid irAEs during ICIs therapy. Primary hypothyroidism was the most common irAEs, occurring in 31 patients (28.18% of the whole cohort), including 14 patients who experienced a transient thyrotoxicosis. About 60% of irAEs occurred within the first 8 weeks of therapy. At multivariate analysis, anti-thyroid autoantibodies positivity at baseline (OR 18.471, p = 0.022), a pre-existing (autoimmune and non-autoimmune) thyroid disorder (OR 16.307, p < 0.001), and a family history of thyroid diseases (OR = 9.287, p = 0.002) were independent predictors of the development of thyroid irAEs.

CONCLUSION: Our data confirm the high frequency of thyroid dysfunctions (mostly hypothyroidism) during ICIs, and provide data on valuable predictors of thyroid toxicities that may help clinicians in identifying patients at risk for developing irAEs.

ABSTRACT

The association between intravascular photobiomodulation (iPBM) and crossed cerebellar diaschisis (CCD) and cognitive dysfunction in patients with traumatic brain injury (TBI) remains unknown. We postulate that iPBM might enable greater neurologic improvements. The objective of this study was to evaluate the clinical impact of iPBM on the prognosis of patients with TBI. In this longitudinal study, patients who were diagnosed with TBI were recruited. CCD was identified from brain perfusion images when the uptake difference of both cerebella was > 20%. Thus, two groups were identified: CCD( +) and CCD( -). All patients received general traditional physical therapy and three courses of iPBM (helium-neon laser illuminator, 632.8 nm). Treatment assemblies were conducted on weekdays for 2 consecutive weeks as a solitary treatment course. Three courses of iPBM were performed over 2-3 months, with 1-3 weeks of rest between each course. The outcomes were measured using the Rancho Los Amigos Levels of Cognitive Functioning (LCF) tool. The chi-square test was used to compare categorical variables. Generalized estimating equations were used to verify the associations of various effects between the two groups. p < 0.05 indicated a statistically significant difference. Thirty patients were included and classified into the CCD( +) and CCD( -) groups (n = 15, each group). Statistics showed that before iPBM, CCD in the CCD( +) group was 2.74 (exp 1.0081) times higher than that of CCD( -) group (p = 0.1632). After iPBM, the CCD was 0.64 (exp-0.4436) times lower in the CCD( +) group than in the CCD( -) group (p < 0.0001). Cognitive assessment revealed that, before iPBM, the CCD( +) group had a non-significantly 0.1030 lower LCF score than that of CCD( -) group (p = 0.1632). Similarly, the CCD( +) group had a non-significantly 0.0013 higher score than that of CCD( -) after iPBM treatment (p = 0.7041), indicating no significant differences between the CCD( +) or CCD( -) following iPBM and general physical therapy. CCD was less likely to appear in iPBM-treated patients. Additionally, iPBM was not associated with LCF score. Administration of iPBM could be applied in TBI patients to reduce the occurrence of CCD. The study failed to show differences in cognitive function after iPBM, which still serves as an alternative non-pharmacological intervention.

ABSTRACT

PURPOSE: The treatment options for canalicular obstruction remain controversial, and there are different approaches. In this study, we aimed to evaluate the success of balloon dilatation and silicon tube intubation according to the etiology in patients with canalicular obstruction.

METHODS: The files of 91 patients with isolated monocanalicular obstruction were retrospectively reviewed. Patients were grouped according to surgical methods (Group A: both balloon dilatation and silicon tube intubation; Group B: Only balloon dilatation) and etiologies (topical anti-glaucomatous usage-related, inflammatory, chemotherapy-related, radiotherapy-related, trauma-related, idiopathic). Preoperative and postoperative Munk scores and lacrimal irrigation results were noted in all cases.

RESULTS: Munk score was found to be statistically significantly lower in the 1st year in both groups. The patency rate with lacrimal syringing was found to be statistically significantly higher in group A. Success rates both in the munk score and lacrimal passage patency were found to be statistically significantly lower in inflammatory etiology than other etiologies.

CONCLUSIONS: Both techniques can be used as first-line therapies for canalicular obstruction. It should be considered that recurrence may develop in stenosis of inflammatory origin and more invasive surgery may be required.

ABSTRACT

Non-hypotensive hypovolemia simulated with oscillatory lower body negative pressure in the range of -10 to -20 mmHg is associated with vasoconstriction {increase in total peripheral vascular resistance (TPVR)}. Due to the mechanical stiffening of vessels, there is a disjuncture of mechano-neural coupling at the level of arterial baroreceptors which has not been investigated. The study was designed to quantify both the cardiac and vascular arms of the baroreflex using an approach based on Wiener-Granger causality (WGC) – partial directed coherence (PDC). Thirty-three healthy human volunteers were recruited and continuous heart rate and blood pressure {systolic (SBP), diastolic (DBP), and mean (MBP)} were recorded. The measurements were taken in resting state, at -10 mmHg (level 1) and -15 mmHg (level 2). Spectral causality – PDC was estimated from the MVAR model in the low-frequency band using the GMAC MatLab toolbox. PDC from SBP and MBP to RR interval and TPVR was calculated. The PDC from MBP to RR interval showed no significant change at -10 mmHg and -15 mmHg. No significant change in PDC from MBP to TPVR at -10 mmHg and -15 mmHg was observed. Similar results were obtained for PDC estimation using SBP as input. However, a significant increase in TPVR from baseline at both levels of oscillatory LBNP (p-value <0.001). No statistically significant change in PDC from blood pressure to RR interval and blood pressure to TPVR implies that vasoconstriction is not associated with activation of the arterial baroreflex in ≤-15 mmHg LBNP. Thereby, indicating the role of cardiopulmonary reflexes during the low level of LBNP simulated non-hypotensive hypovolemia.

ABSTRACT

BACKGROUND: Adhesive capsulitis is a progressive, idiopathic disorder that significantly impacts individuals̓ daily lives and increases their medical burden. Pharmacopuncture therapy, which combines acupuncture techniques with herbal medicine, involves injecting herbal extracts into specific acupoints. This study aims to determine the effectiveness and safety of pharmacopuncture therapy in comparison to physiotherapy (PT) for treating adhesive capsulitis.

METHODS: This research protocol outlines a two-arm, parallel, multi-center, pragmatic randomized controlled trial. Fifty participants will be randomly allocated to either the pharmacopuncture therapy or PT group, and they will receive 12 sessions of their respective therapies over a 6-week period. The primary outcome measure is the numeric rating scale for shoulder pain. Secondary outcomes include the visual analog scale score for shoulder pain, Shoulder Pain and Disability Index, Patients̓ Global Impression of Change score, Short Form-12 Health Survey Version 2 score, and EuroQol-5 Dimension. Statistical analysis will be conducted based on the intention-to-treat principle.

DISCUSSION: This trial may offer high-quality and reliable clinical evidence for evaluating the effectiveness and safety of pharmacopuncture therapy compared to PT in the treatment of adhesive capsulitis. Furthermore, this study will serve as a valuable guideline for practitioners when making clinical decisions and managing adhesive capsulitis.
