Published: August 2024

Background The Nuss procedure is the primary treatment for pectus excavatum (PE), but patient expectations are not always met. In our unit, our standard approach in the last few years has been the routine application of two bars instead of one. We aimed to retrospectively assess the impact of this approach on patient satisfaction, quality of life (QoL) and safety. Methods A retrospective study included 182 patients over 16 years old who underwent the Nuss procedure for PE between January 2007 and September 2021. Patients were categorized into one-bar or two-bar correction groups. Propensity score matching (PSM) was used, resulting in 30 patients in each group. Primary endpoints were QoL and cosmetic satisfaction, while secondary endpoints included complications and recurrence. Results After PSM, both groups showed similar general characteristics. Patients treated with two bars reported fewer psychological complaints post-surgery (93.3% vs. 73.3%, p = 0.031). There were no significant differences in QoL improvement (96.7% in both groups, p = 0.197), perioperative complications ( p = 0.771) or recurrence (one patient in the one-bar group, p = 1.000). Conclusions Our study reveals that patients undergoing the Nuss Procedure for PE with two bars exhibit comparable clinical outcomes and QoL to those with one bar. However, patients with two bars may have higher levels of psychological well-being and satisfaction, indicating potential benefits associated with this approach. These findings suggest potential advantages of the two-bar approach, but further research with larger sample sizes is warranted to confirm these observations.

Objectives To investigate the effect of targeted nursing intervention on the short-term prognosis of patients with coronary heart disease and carotid artery stenosis undergoing synchronous coronary artery bypass grafting (CABG) and carotid endarterectomy (CEA). Methods A total of 58 patients who received OPCABG + CEA from February 2018 to May 2021 at the Beijing Anzhen Hospital were selected as the study subjects. They were randomly divided into two groups, with 29 patients in each group. The control group received routine postoperative nursing care, while the observation group received targeted nursing intervention in addition to the routine care. The incidence of postoperative stroke and the length of postoperative stay were observed. Results There were no statistically significant differences in baseline data between the two groups. Postoperative acute stroke occurred in 2 cases (6.9%) in the control group and 0 cases in the observation group, although this difference was not statistically significant. The median postoperative hospital stay was 13 days in the control group, with the earliest discharge at 10 days. In the observation group, the median postoperative hospital stay was 10 days, with the earliest discharge on the 8th day. This difference was statistically significant. Conclusions Targeted nursing intervention can improve the short-term prognosis of patients with coronary heart disease and carotid artery stenosis undergoing OPCABG + CEA, and it can also shorten the length of postoperative hospital stay.

Authors: Singh Bhavna , Ahluwalia Rajiv 
Published: August 2024

Objective To evaluate the changes in buccal corridor and smile index, with respect to age and gender, in a randomly selected sample of the North Indian population. Materials and Methods Perioral musculature of 195 subjects (divided into three age groups) was recorded using standardized videographic method. The frame representing subject’s “widest posed smile,” was selected and analyzed to evaluate selected smile parameters. Results Buccal corridor decreased significantly for overall as well as female sample population, whereas it was fairly unchanged for males. No significant variation was noted for smile index. Conclusions As a person ages, the smile gets narrower vertically as well as transversely, with the change being greater in the transverse dimension. Age-related changes must be considered for delivering long-lasting orthodontic results.

Published: August 2024

Background: The acetabular sourcil is commonly interpreted as a reliable radiographic representation of the weightbearing dome of the acetabulum, despite limited modern data. Assessment of weightbearing acetabular coverage has been described using both the sourcil edge and bone edge as anatomic landmarks, leading to confusion and potential misguidance in surgical decision-making and thus compromised patient outcomes. Purpose/Hypothesis: The purpose of this study was to characterize the 3-dimensional (3D) anatomic correlates of the sourcil-edge and bone-edge radiographic measurements on false-profile radiographs. It was hypothesized that the sourcil edge would represent anterolateral coverage and the bone edge would represent anterior coverage. Study Design: Descriptive laboratory study. Methods: A total of 80 hips were grouped by large or small differences between bone-edge and sourcil-edge anterior center-edge angles, based on upper and lower quartiles of discrepancy. Three-dimensional surface mesh models and digitally reconstructed radiographs were generated from hip computed tomography scans. Sourcil-edge and bone-edge anterior center-edge angles were identified on digitally reconstructed radiographs and registered to the 3D models with fiducial markers. Intersections of bone-edge and sourcil-edge projection lines with the acetabular rim were obtained from the 3D models. Results: The bone-edge and sourcil-edge projections intersected the acetabular rim at clockface means of 2:05 ± 0:22 and 1:12 ± 0:25, respectively. The 3D models consistently demonstrated that, in both large- and small-discrepancy groups, the sourcil edge corresponded to the acetabular area just posterior to the anterior inferior iliac spine (AIIS) projection, and the bone edge corresponded to the weightbearing region inferior to the AIIS. Additionally, in large-discrepancy hips, the bone edge corresponded to more prominent acetabular coverage in the region inferomedial to the AIIS when compared with the small-discrepancy hips. Conclusion: On false-profile radiographs, the sourcil edge corresponds to superior femoral head coverage, and the bone edge corresponds to anterosuperior coverage. Radiographs with a large discrepancy between sourcil-edge and bone-edge measurements demonstrate acetabular rim prominence in the region of the AIIS. Clinical Relevance: Characterizing the anatomic weightbearing regions of the acetabulum represented on false-profile radiographs facilitates improved clinical and intraoperative decision-making in hip preservation surgery, including acetabuloplasty and periacetabular osteotomy.

Published: August 2024

In view of the impact resistance of PVB laminated glass, PVB laminated glass of 0.76 mm and 1.52 mm thickness was selected in this paper to form five different types of “2 + 1” and “3 + 2” sandwich glass, and hydrogen gun flying plate variable speed impact combined with CT scanning and three-dimensional reconstruction technology was adopted. The failure mode and crack expansion of glass specimens after impact are studied. The influence of different factors (sandwich thickness, sandwich number, and sandwich position) on the impact resistance of explosion-proof glass is analyzed comprehensively. The results show that increasing the number and thickness of sandwiches can reduce the widening and expansion of microcracks, decrease crack connectivity, and effectively resist plastic damage to glass specimens. The appropriate position of the sandwich helps to improve the load-bearing capacity of the glass specimens. Therefore, the thickness of the sandwich, the number of sandwiches, and the position of the sandwich all have an impact on the impact load capacity and crack development of laminated glass. In addition, the impact resistance of laminated glass is positively correlated with the thickness of the PVB sandwich but shows different damage sensitivity to different impact velocities, with the best impact resistance under its medium velocity condition. This paper provides a significant theoretical foundation for establishing selection criteria for explosion-proof glass by examining the factors that influence its impact resistance, thereby enhancing its safety performance.

Authors: Tang Michelle , Nunna Nitya , Zhong Qing 
Published: August 2024

Background: Amiodarone-induced anaphylaxis is seldom reported. The mechanism of this anaphylaxis is unknown. Methods: A literature search was carried out with keywords “Amiodarone” and “Anaphylaxis” and “polysorbate 80” or “hypotension.” A search using “amiodarone” in the FDA Adverse Event Reporting System (FAERS) from 1969 to 2024 was also conducted. Results: There are a total of 10 cases of amiodarone-induced anaphylaxis in the literature. Six patients were male. Ages ranged from 15 to 86 years old. Nine cases were triggered by intravenous injection (IV) and one by oral administration. Eight patients did not have previous exposure to amiodarone. The trigger times for IV amiodarone were immediate to 90 minutes. All nine cases of IV amiodarone resulted in hypotension (90%), with an immeasurable blood pressure (70%). Presentations included bronchospasm or a skin rash (60%), angioedema (40%), and unconsciousness (20%). Only one patient had a history of allergy to penicillin and sulfonamide. An amiodarone skin test was positive on one patient. Increased blood tryptase (4 cases), positive basophil activation test to amiodarone (2 cases), increased eosinophil count (1 case), and increased serum IgE (1 case) were reported. Amiodarone was terminated in 80% of the patients. Epinephrine, norepinephrine, antihistamine-1, or steroids were used to rescue patients. Four patients were intubated. All patients fully recovered. In the FAERS database, 89 cases of amiodarone-associated anaphylaxis were reported, resulting in 14 deaths. Conclusions: Solvent polysorbate 80, amiodarone, and iodide may contribute to amiodarone-induced anaphylaxis. Prompt treatment is the key to saving patients.

Published: August 2024

Background: Cultivating internal whistleblowing among nurses is of paramount importance to nurse leaders. Yet, the literature on how nurse leaders can foster this phenomenon among nurses is limited. Additionally, the underlying mechanisms linking leadership behaviors to internal whistleblowing intentions remain underexplored. Aim: This study aimed to examine how ethical leadership is linked to internal whistleblowing intentions among nurses through the mediating effect of psychological safety. Research design: A multicenter cross-sectional research design was used for this study. Participants and research context: This study involved 201 nurses working in three tertiary governmental hospitals across three cities in Egypt. Data were collected between October and December 2023, using an introductory information form, the Ethical Leadership Scale, the Psychological Safety Scale, and the Internal Whistleblowing Intentions Scale. Structural equation modeling was used to evaluate study hypotheses. Ethical consideration: Research Ethics Committee of Faculty of Nursing, Port Said University, Egypt approved the study (reference number: NUR (6/8/2023)(28)), and each participant signed the informed consent form before participation in the study. Results: Ethical leadership was positively linked to nurses’ psychological safety and internal whistleblowing intentions. Psychological safety mediated the link between ethical leadership and nurses’ internal whistleblowing intentions. Conclusion: Our study suggests that nurse leaders can foster nurses’ intentions to blow the whistle internally by adopting ethical leadership behaviors and enhancing psychological safety among nurses.

Authors: Cabrera Jesús Antonio López , Mata Enrique González , Wu Juan Quiñonez 
Published: August 2024

This study aims to recognize and succinctly evaluate the monetary policy implemented during the COVID-19 pandemic, as well as in the immediate recovery period, and their economic impact in Central America and the Dominican Republic (CARD). To this end, the study carries out a qualitative and quantitative analysis of the monetary policy implemented to reduce the negative economic impact on CARD, during the period 2020–2022. VAR and panel econometric techniques were used for the analysis. The results show that even though the central banks of CARD countries did indeed seek to stimulate economic activity, the effects on aggregate economic activity are very small. Other types of policies, such as fiscal, financial, and regulatory policies, may have contributed to reducing to a greater extent the negative impact of the COVID-19 pandemic on economic activity.

Published: August 2024

Introduction The levator veli palatini (LVP) muscle has two segments with distinct roles in velopharyngeal function. Previous research suggests longer extravelar segments with shorter intravelar segments may lead to a more advantageous mechanism for velopharyngeal closure. The purpose of this study was to examine whether the distribution of the LVP intravelar and extravelar segments differs between children with cleft palate with and without VPI and controls. Methods The study included 97 children: 37 with cleft palate +/- lip with VPI, 37 controls, and 19 with cleft palate with normal resonance. Measures included mean LVP length, mean extravelar LVP length, and intravelar LVP length. Results Overall mean LVP length was similar ( P = .267) between controls and children with cleft palate (with and without VPI). However, there was a significant difference ( P < .001) between group for both intravelar and extravelar LVP lengths: the intravelar segment was significantly longer in those with VPI compared to controls and children with cleft palate and normal resonance; and the extravelar segment was significantly shorter in those with VPI compared to controls and children with cleft palate and normal resonance. Conclusions Results from this study demonstrate a significant difference between the distribution of the functional segments of the LVP among children with VPI, with a more disadvantageous distribution of the muscle segments among those with VPI.

Published: August 2024

Objective Prospectively validate the accuracy of smartphone-based digital cranial measurements for the diagnosis and treatment of deformational plagiocephaly and/or brachycephaly (DPB), compared with calipers used in the standard of care. Design/Methods Bird's-eye-view head photos were captured via smartphone, and their heads were measured with hand calipers by an expert user. CI/CVAI/CVA were calculated from photos and caliper measurements, and from 3D photogrammetry of the head as ground truth. Digital and caliper measurements were compared against 3D-based ground truth using mean absolute error, Spearman correlation coefficient, and Bland-Altman method. Statistical significance between methods was assessed using Wilcoxon Rank-Sum test. Participants 71 infants aged 2–11 months (20 female, 51 male) with DPB Results The mean absolute errors for CI, CVAI, CVA were 1.63 ± 1.44, 1.45 ± 1.29, 2.38 ± 1.86 mm for smartphone, and 2.60 ± 1.96, 1.43 ± 1.22, 2.04 ± 1.81 mm for calipers, respectively. The correlation coefficients for CI, CVAI, CVA between smartphone and ground truth were 0.90, 0.94, 0.80 (p < 0.001), and 0.87, 0.93, 0.84 (p < 0.001) between calipers and ground truth, respectively. Bland-Altman results were (0.08, [−4.18, 4.34]), (−0.05, [−3.85, 3.76]), (−0.82, [−6.52, 4.87]) for smartphone, and (1.41, [−4.34, 7.15]), (0.28, [−3.37, 3.94]), (0.16, [−5.18, 5.49]) for caliper measurements respectively. Digital and caliper measurements were similar (p = 0.12) except for CI, where digital measurements were more accurate (p = 0.04). Conclusion Smartphone-based cranial measurements have very high correlation with 3D-based ground truth, and they are comparable or superior to caliper measurements. Digital measurements can be performed in pediatric offices or from home to help with the early detection and treatment of DPB.

Objective In managing sagittal craniosynostosis, strip craniectomy of the affected suture is commonly paired with barrel-stave osteotomies to allow for additional cranial remodeling. However, the effect of these osteotomies is not well-established. This study aimed to evaluate the effect of the length of barrel-stave osteotomies on outcomes in patients with sagittal craniosynostosis. Design A retrospective review of operative records and pre-operative and one-year post-operative three-dimensional images. Setting Tertiary care pediatric institution. Patients Forty-five patients with sagittal craniosynostosis Interventions Sagittal strip craniectomy and either long, medium, or short barrel-stave osteotomy lengths followed by helmet therapy Main Outcome Measures Operative and three-dimensional craniometric outcomes. Results Operative time, estimated blood loss, and hospital length of stay were significantly decreased in the short group ( P = .003; 0.002; 0.027). The cranial index was normalized in all groups, but the long group was significantly lower ( P = .007; 0.025). Head circumference was similar between groups. All indexes were within the normal percentiles in all groups. The medium group had a significantly decreased scaphocephalic index ( P = .031; .035). The short group had significantly greater occipital bulleting than the medium group ( P = .001). The long group had significantly greater narrowing than the short group ( P = .036). Conclusions Strip craniectomy with the addition of long, medium, or short barrel staves all resulted in clinically successful outcomes. Our findings suggest that increased barrel-stave osteotomy length may not be necessary for a successful outcome while avoiding more extensive dissection, potential risk, increased operative time, and hospital length of stay.

Published: August 2024

Objective: To investigate the accuracy of full arch scans taken using the iTero Element 2® under clinical settings. Design: Prospective clinical study. Methods: A customised upper removable appliance (URA) with four spheres (A–D) was fabricated from a maxillary arch iTero® scan for a 24-year-old patient. Six linear values were measured on the URA using a high-accuracy coordinate measuring machine. A total of 60 intra-oral iTero® scans were taken by two operators (HA and AS) with the test URA inserted to the participant’s maxillary dentition at T1 and T2. Geomagic Control X software was used to measure the six linear distances between the reference spheres (1–4) in all scans. Comparisons between distances on full arch scans to true distances on the URA were made to evaluate accuracy. Results: The median distance to the prepared bench top URA mean was significantly away from zero for each operator and timepoint across all measurements except AD versus 14 and BD versus 24. Statistically significant, although clinically non-significant, differences in median linear distances in relation to the prepared benchtop URA were observed between evaluators in segments AB versus 12 (operator 1 −0.021 mm vs. operator 2 −0.06 mm) and AC vs. 13 (operator 1 −0.044 mm vs. operator 2 −0.167 mm) at T1. Conclusion: The accuracy of scanners is defined as the trueness and precision of the captured scans to the dental arches. The accuracy of iTero Element 2® is acceptable for diagnosis and treatment planning in orthodontics. Length and location of the scanned segment and scanning sequence ‘protocol’ affect accuracy.

Published: August 2024

Background: Cancer and psychiatric symptoms are associated. Fear of cancer recurrence (FCR) is the most common psychological problem for cancer survivors. Pharmacological interventions can help, but also have major drawbacks. Music therapy and music interventions have been shown to be a safe and practical complementary treatment. Objective: This randomized, controlled trial aimed to investigate the effects of music therapy and music intervention in attenuating non-small cell lung cancer (NSCLC) patients’ anxiety related to FCR. Methods: NSCLC patients with FCR were randomly allocated to a music therapy and intervention group (G1) and Control group (G2). Patients’ anxiety was measured using the State-Trait Anxiety Inventory scores and heart rates. Primary outcome measure were PET scans. Secondary measures were salivary cortisol, salivary α-amylase levels and heart rate. Findings: Patients in G1 showed higher glucose metabolism of 18F-FDG in the superior frontal gyrus, anterior cingulate, superior temporal gyrus, and parahippocampal gyrus, compared to those in G2 (all P < .001). Heart rates and salivary α-amylase area under the curve (AUC) and relative variation (VAR) in G1 were significantly lower than those in G2 (all P < .05). State-Trait Anxiety Inventory scores and cortisol AUC in G1 were significantly lower than those in G2 (all P < .05). Conclusions: Music therapy and interventions can reduce anxiety and endocrinological responses and change glucose metabolism of 18F-FDG in fear-related brain regions. Trial registration: Registered retrospectively, ISRCTN Registry, www.isrctn.com, ISRCTN23276302 Clinical Implications: Cancer treatment centers and physical examination centers should consider providing music therapy and intervention to the appropriate patients as a routine component of a comprehensive clinical care during medical examinations.
