Published: September 2024

Objective A ballistocardiogram (BCG) is a vibration signal generated by the ejection of the blood in each cardiac cycle. The BCG has significant variability in amplitude, temporal aspects, and the deficiency of waveform components, attributed to individual differences, instantaneous heart rate, and the posture of the person being measured. This variability may make methods of extracting J-waves, the most distinct components of BCG less generalizable so that the J-waves could not be precisely localized, and further analysis is difficult. This study is dedicated to solving the variability of BCG to achieve accurate feature extraction. Methods Inspired by the generation mechanism of the BCG, we proposed an original method based on a profile of second-order derivative of BCG waveform (2ndD-P) to capture the nature of vibration and solve the variability, thereby accurately localizing the components especially when the J-wave is not prominent. Results In this study, 51 recordings of resting state and 11 recordings of high-heart-rate from 24 participants were used to validate the algorithm. Each recording lasts about 3 min. For resting state data, the sensitivity and positive predictivity of proposed method are: 98.29% and 98.64%, respectively. For high-heart-rate data, the proposed method achieved a performance comparable to those of low-heart-rate: 97.14% and 99.01% for sensitivity and positive predictivity, respectively. Conclusion Our proposed method can detect the peaks of the J-wave more accurately than conventional extraction methods, under the presence of different types of variability. Higher performance was achieved for BCG with non-prominent J-waves, in both low- and high-heart-rate cases.

Published: September 2024

Introduction: It is unclear whether the risk of suicide differs among individuals with only physical health condition, those with only mental health conditions, and those with both types of conditions (multimorbidity) and how emotional social support modifies these associations. This study aimed to examine differences in the association of suicidal ideation with the presence of only physical health conditions, only mental health conditions, and multimorbidity and the modifying role of emotional social support in these associations. Methods: A cross-sectional survey was conducted between August and September 2023 in a Japanese rural town to collect data. The exposure variable was the health condition, and it was classified into 4 groups: disease-free, only physical health conditions, only mental health conditions, and multimorbidity. The outcome variable was suicidal ideation. The data collected were analyzed using multivariate logistic regression analysis and stratified analysis. Results: Suicidal ideation was found to have a significant positive association with the presence of only mental health conditions and multimorbidity. These associations remained unchanged in the absence of emotional social support. However, the odds ratio for the only mental health conditions group decreased in the presence of emotional social support, while the odds ratio for the multimorbidity group remained significantly higher. Conclusions: Suicidal ideation is positively associated with the presence of only mental health conditions and multimorbidity, but emotional social support modifies only the association between suicidal ideation and the presence of only mental health conditions. These results suggest that it may be important to identify the type of social support one needs based on one’s health condition to prevent suicide.

Background The World Database for Pediatric and Congenital Heart Surgery (WDPCHS), sponsored by the World Society for Pediatric and Congenital Heart Surgery (WSPCHS), provides complex congenital heart surgery outcomes analyses for member programs. This report represents the seven-year descriptive analysis of outcomes from active members of the WDPCHS. Methods Individual institutions submit data based on the specific procedure via a password protected platform. The data are collected, stored, and analyzed at Kirklin Solutions Inc., based in Birmingham, Alabama. This report presents a descriptive analysis of these procedures submitted from January 1, 2017, to December 31, 2023. Results A total of 50,174 procedures were submitted with an overall mortality of 4.6%. The majority of submissions were from Asian countries. The majority of cases submitted from these countries were of STAT mortality category I and II. Repair of a ventricular septal defect (with a mortality of 0.8%) and correction of tetralogy of Fallot (2.0% mortality) were the most common procedures submitted to the database. Conclusions The WSPCHS accomplished one of its missions in 2017 when the WDPCHS began accepting data from pediatric and congenital heart surgery programs across the globe. In doing so, it became one of the first organizations to create a platform for the exchange of knowledge and experience, regardless of the socioeconomic status of the particular program or country.

Study Design Retrospective Cohort Study. Objectives Length of Stay (LOS) and resource utilization are of primary importance for hospital administration. This study aimed to understand the incremental effect of having a specific complication on LOS among ASD patients. Methods A retrospective examination of prospective multicenter data utilized patients without a complication prior to discharge to develop a patient-adjusted and surgery-adjusted predictive model of LOS among ASD patients. The model was later applied to patients with at least 1 complication prior to discharge to investigate incremental effect of each identified complication on LOS vs the expected LOS. Results 571/1494 (38.2%) patients experienced at least 1 complication before discharge with a median LOS of 7 [IQR 5 to 9]. Univariate analysis demonstrated that LOS was significantly affected by patients’ demographics (age, CCI, sex, disability, deformity) and surgical strategy (invasiveness, fusion length, posterior MIS fusion, direct decompression, osteotomy severity, IBF use, EBL, ASA, ICU stay, day between stages, Date of Sx). Using patients with at least 1 complication prior discharge and compared to the patient-and-surgery adjusted prediction, having a minor complication increased the expected LOS by 0.9 day(s), a major complication by 3.9 days, and a major complication with reoperation by 6.3 days. Conclusion Complications following surgery for ASD correction have different, but predictable impact on LOS. Some complications requiring minimal intervention are associated with significant and substantial increases in LOS, while complications with significant impact on patient quality of life may have no influence on LOS.

Background Early initiation of antiretroviral therapy improves human immunodeficiency virus (HIV) outcomes. However, achieving earlier treatment initiation is challenging for many reasons including provider awareness and clinic barriers; this study sought to understand perceptions of an early initiation program. Methods We interviewed 10 providers from 3 HIV clinics in North Carolina (October-November 2020). We asked providers about overall perceptions of early initiation and the pilot program. We developed narrative summaries to understand individual contexts and conducted thematic analysis using NVivo. Results Providers believed earlier initiation would signal an “extra sense of urgency” about the importance of antiretroviral therapy—a message not currently reflected in standard of care. Safety was a consistent concern. Cited implementation barriers included transportation assistance, medication sustainability, and guidance to address increased staff time and appointment availability. Conclusion Our qualitative findings highlight the need for training on the safety of early initiation and addressing staffing needs to accommodate quicker appointments.

Objective This study investigated women living with HIV/AIDS (WLHA)'s practices and decision-making regarding disclosure of HIV status in healthcare settings in Vietnam. Introduction: Disclosure of HIV status in healthcare settings is under-studied. Methods We conducted in-depth interviews with 30 WLHA in Hanoi, Vietnam. Thematic analysis was conducted to investigate the patterns, considerations, and consequences of HIV disclosure. Results: Most participants chose a selective disclosure strategy based on the type of procedure and healthcare setting. They considered several factors: concerns about stigma/discrimination, risks of confidentiality breach, relevance to healthcare provision, and altruism towards protecting providers and other patients. Selective disclosure or non-disclosure often prevented participants from accessing comprehensive care. Conclusion: The study underscores the need to prepare WLHA to make informed decisions regarding disclosure and provide them with service navigations and support. It also highlights the necessity of reducing stigma and enhancing confidentiality protection to ensure safe disclosure in healthcare settings.

Published: September 2024

Background: The relationship between self-reported symptoms and the severity of patellar tendon abnormality (PTA) as seen on magnetic resonance imaging and ultrasound is unclear, but biomechanical testing may resolve this. Purpose: To (1) compare land-jump limb biomechanics between pre- and postseason timepoints, (2) assess whether seasonal changes in biomechanics are associated with seasonal changes in PTA and symptom severity, and (3) explore models that identify seasonal changes in PTA and symptoms with seasonal changes in biomechanics in collegiate basketball players. Study Design: Cohort study; Level of evidence, 2. Methods: Victorian Institute of Sport Assessment Scale – Patellar Tendon (VISA-P) scores and bilateral measurements from 18 National Collegiate Athletic Association Division I and II male basketball players (n = 36 limbs) at the preseason (visit 1) and postseason (visit 2) timepoints were collected. PTA was graded with ultrasound and magnetic resonance imaging morphology measurements proximally and distally, and 3-dimensional lower extremity sagittal kinematics and kinetics were measured during a land-jump test. Multivariate and chi-square analyses assessed timepoint differences. The association of seasonal (Δ = visit 2 - visit 1) biomechanics with seasonal morphology (ΔPTA: no change/worsened) and symptoms (ΔVISA-P: improved/no change/worsened) was tested with multivariate models. Logistic regressions modeled the accuracy of seasonal biomechanics to classify seasonal PTA and symptoms. Results: Three athletes (6 limbs) at visit 1 and 2 athletes (4 limbs) at visit 2 were symptomatic. VISA-P scores were not significantly different between preseason and postseason. Regarding PTA, multivariate analyses found differences among grouped ground-reaction force variables ( P < .05); univariate analyses found that worsened PTA was associated with seasonal decreases in peak vertical jumping force and with seasonal increases in knee flexion velocity at contact and maximum knee flexion velocity ( P < .05 for all). Regarding VISA-P scores, multivariate analyses found differences among grouped hip ( P < .01) and ankle ( P < .05) kinematic variables; univariate analyses found that worsened VISA-P was associated with seasonal increases in hip ( P < .01) and knee ( P < .01) flexion velocity at contact and seasonal increases in ankle range of motion ( P < .05). Conclusion: The findings demonstrated an association between seasonal changes in dynamic lower extremity biomechanics and seasonal changes in patellar tendon imaging signals as well as self-reported symptoms.

Authors: Oh Sang Yun , Kim Yong Tae , Lee Kyung Jae , Kim Sae Hoon 
Published: September 2024

Background: The management of irreparable rotator cuff tears presents a surgical dilemma. However, supraspinatus muscle advancement (MA) could be used to convert irreparable to reparable tears without requiring a graft. Purpose: To compare the outcomes of patients with an irreparable tear who underwent rotator cuff repair with MA with those with a reparable large to massive cuff tear who underwent rotator cuff repair. Study Design: Cohort study; Level of evidence, 3. Methods: We enrolled 62 patients who underwent rotator cuff repair for a large to massive tear between January 2020 and May 2022. Among them, 29 patients underwent an MA procedure due to an inability to repair despite releases (MA group), whereas the other 33 patients did not require the procedure (NMA group). At 1 year postoperatively, follow-up assessments including magnetic resonance imaging were performed to evaluate group outcomes. Results: Despite there being more revision surgery cases and a poorer potential for cuff healing in the MA group, the retear rates in the MA and NMA groups were similar (31.0% vs 21.2%, respectively; P = .401), as were clinical outcomes, including the visual analog scale for pain (2.9 vs 1.9; P = .076), University of California, Los Angeles (27.0 vs 29.1; P = .185), Constant (70.1 vs 74.9; P = .063), and American Shoulder and Elbow Surgeons (74.5 vs 81.8; P = .168) scores. Postoperative muscle power during forward elevation was weaker in the MA group than in the NMA group (35.1 vs 45.8 N; P = .052), but external rotation power was comparable (49.3 vs 59.0 N; P = .121). Progress in fatty degeneration of the supraspinatus was not significantly different in the 2 groups ( P = .43), although the MA group showed a nonsignificant decrease in supraspinatus atrophy ( P = .092) due to the lateral shift produced by the procedure. Conclusion: The MA procedure for irreparable tears produced outcomes comparable with reparable tears, offering a valuable perspective on the efficiency of the procedure. The comparable but relatively high retear rates emphasize the need for further studies to compare with other treatment options for irreparable tears.
Insurance Status, Language, and Access to Care for Pediatric Anterior Cruciate Ligament Injury
Authors: Park Anna L. , Singh Dhillon Pardeep , Pandya Nirav K. 
Published: September 2024

Background: Patients with public insurance (PUBs) face more difficulty obtaining orthopaedic appointments and have longer wait times than privately insured patients (PVTs). These delays are associated with greater injury severity at the time of surgery, which affects sports injuries such as anterior cruciate ligament tears where early surgical stabilization leads to better outcomes. Additionally, previous evidence showed that patients with limited English proficiency often must rely on informal translation services, such as family members or friends, to communicate with their orthopaedic surgeons, which may represent a disparity in the care provided. Hypothesis: It was hypothesized that PUBs would be less likely to obtain an appointment compared with PVTs and that most providers would not offer professional translation services to Spanish-speaking patients. Study Design: Cross-sectional study. Methods: The authors called 50 randomly selected orthopaedic surgeons’ offices in California specializing in sports medicine to request an appointment. Each office was called 4 times in random order for the hypothetical patient having either private or public insurance and speaking either Spanish or English. Results: The hypothetical PUB had significantly decreased access to an appointment (19% of offices offered an appointment) when compared to the PVT (73.8% offered an appointment). Independent private practice (IPP) offices were less likely to accept public insurance (13.3%) compared with offices at academic medical centers (57.1%). There was no difference in access to an appointment for the Spanish- versus English-speaking patient. Translation services were offered at 73.8% of the orthopaedic offices. Conclusion: Overall, the data illustrated disparities in access to pediatric orthopaedic care for PUBs compared to those with private insurance. Disparities were most prominent in IPP settings, which were less likely than academic offices to accept public insurance. Additionally, it was found that 73.8% of the offices the authors contacted offered Spanish translation services. Interventions should focus on increasing acceptance of public insurance and translation services in IPP settings. Future studies should expand this analysis to other languages and investigate the potential impacts of language on the quality of care provided.

Published: September 2024

Interpersonal violence is a common type of trauma experienced by people with opioid use disorder (OUD), especially for people with co-occurring OUD and mental illness (COD). However, little is known about demographic and clinical characteristics of individuals with COD who have experienced an interpersonal violence traumatic event compared to those who have experienced a non-violent trauma, and how experiences of interpersonal violence are associated with treatment utilization. Data presented are from a randomized clinical trial testing collaborative care for COD in primary care. Of the 797 patients enrolled in the larger study, 733 (92%) were included in this analysis because they reported a traumatic event. In this sample, 301 (41%) participants experienced a traumatic event involving interpersonal violence. Participants who experienced interpersonal violence were more likely to be younger and female. Among the 301 people who experienced interpersonal violence, 30% experienced child sexual abuse, 23% experienced physical violence, 19% experienced domestic violence, and 28% experienced sexual assault. Those who experienced physical violence were significantly less likely to be female (28.6% vs 74.2% to 88.2% in other groups). Those who reported domestic violence had significantly fewer days of drug use (4.1 days vs 9.0 to 11.5 in the other groups) and lower opioid use severity scores (mean = 13.0 vs 16.6 to 19.5 in the other groups). Multivariable regression results examining the associations between interpersonal violence experiences on treatment utilization revealed no statistically significant differences. Rates of receipt were high for medication for opioid use disorder (∼80%) in this sample while rates of mental health counseling were around 35% and rates of receiving mental health medication around 48%. These findings make an important contribution to understanding the associations between patient characteristics and traumatic experiences, and receipt of treatment for OUD and mental health problems among a sample of patients with COD.

Background: Festivals play an important role in improving death and grief literacy, enabling members of the public to engage with these often-sensitive topics. Good Grief Weston festival was co-designed and delivered with the community in Weston-super-Mare, a coastal town in South-West England with high levels of socioeconomic disadvantage but rich community assets. It was held in person over 8 days in May 2023. Objectives: To evaluate the reach and impact of Good Grief Weston festival and gather data to inform future festivals. Design: Mixed methods evaluation (survey and focus groups). Methods: Online and paper surveys assessing participants’ characteristics and experiences were administrated during and after the festival. Survey participants who indicated their willingness to participate were invited to attend a focus group. Focus groups were recorded, transcribed and analysed using thematic analysis. Data were collected by trained community co-researchers. Results: Approximately 3000 people attended the festival. Of 204 completed surveys, 64.5% were from women, age range ⩽15 to ⩾75 years; 88.2% identified as White; 14.9% deaf, disabled/with a chronic condition; 18.9% neurodivergent; 9.0% gay, bisexual or queer. Festival participants were entertained (70.9%), inspired (68.5%), felt part of a like-minded community (54.3%), talked to someone new (49.2%), learnt about grief/bereavement (34.3%), shared or expressed experiences (30.3%) and found out about local support (19.7%). 71.3% reported that they felt more confident talking about grief after attending. Median experience rating was 5 (IQR 0; possible range 1 = poor to 5 = excellent). In free-text comments, participants expressed appreciation for the festival and described benefits in attending. Two focus groups were conducted ( n = 8 participants, all women), lasting c.1.5 h. Focus groups added rich descriptions of the festival’s value, and data to inform the next festival. Conclusion: Findings suggest festivals of this nature can play a central role in a public health approach.
