Published: June 2024

Abstract
Background
Healthy eating is one of the most important nonpharmacologic treatments for patients with atherosclerosis(AS). However, it is unclear how elderly AS patients in western China perceive their dietary status and which type of nutritional assistance they would be willing to receive. Therefore, the primary purpose of this study was to understand the level of knowledge about current dietary habits and healthy eating habits among elderly AS patients in western China, and the secondary purpose was to identify acceptable nutritional assistance measures or pathways for those patients to help them manage disease progression.

Methods
An implementation study approach was used to recruit elderly patients with AS-related diseases in western China for semistructured interviews.

Results
14 participants were included in the study, and the following three themes were identified from the interviews:(1) the diet with regional characteristics; (2) low nutrition-related health literacy; (3) complex attitudes towards nutritional assistance. Most participants had misconceptions about healthy eating, and the sources of their knowledge might not be trustworthy. Participants expressed a preference for personalized nutritional assistance, especially that provided by medical-nursing combined institutions.

Conclusion
Patients in western China need nutritional assistance for their regional dietary habits; therefore, healthy dietary patterns consistent with the regional culture are proposed to improve the prevailing lack of knowledge about healthy diets, improve the dietary structure of patients, and control the development of the disease.

Published: June 2024

Abstract
Introduction
Accelerometer-derived physical activity (PA) from cardiac devices are available via remote monitoring platforms yet rarely reviewed in clinical practice. We aimed to investigate the association between PA and clinical measures of frailty and physical functioning.

Methods
The PATTErn study (A study of Physical Activity paTTerns and major health Events in older people with implantable cardiac devices) enrolled participants aged 60 + undergoing remote cardiac monitoring. Frailty was measured using the Fried criteria and gait speed (m/s), and physical functioning by NYHA class and SF-36 physical functioning score. Activity was reported as mean time active/day across 30-days prior to enrolment (30-day PA). Multivariable regression methods were utilised to estimate associations between PA and frailty/functioning (OR = odds ratio, β = beta coefficient, CI = confidence intervals).

Results
Data were available for 140 participants (median age 73, 70.7% male). Median 30-day PA across the analysis cohort was 134.9 min/day (IQR 60.8–195.9). PA was not significantly associated with Fried frailty status on multivariate analysis, however was associated with gait speed (β = 0.04, 95% CI 0.01–0.07, p = 0.01) and measures of physical functioning (NYHA class: OR 0.73, 95% CI 0.57–0.92, p = 0.01, SF-36 physical functioning: β = 4.60, 95% CI 1.38–7.83, p = 0.005).

Conclusions
PA from cardiac devices was associated with physical functioning and gait speed. This highlights the importance of reviewing remote monitoring PA data to identify patients who could benefit from existing interventions. Further research should investigate how to embed this into clinical pathways.

Published: June 2024

Abstract
Background
Hyperphosphatemia is associated with increased morbidity and mortality in patients with end-stage kidney disease (ESKD). Whereas clinical and observational studies have demonstrated the effectiveness of sucroferric oxyhydroxide (SO) in controlling serum phosphorus (sP) in ESKD, data on the real-world impact of switching to SO in patients on peritoneal dialysis (PD) are limited. In this retrospective database analysis, we examine the impact of SO on sP management over a 1-year period among PD patients prescribed SO as part of routine clinical care.

Methods
We analyzed de-identified data from adults on PD in Fresenius Kidney Care clinics who were prescribed SO monotherapy between May 2018 and December 2019 as part of routine clinical management. Changes from baseline in sP levels, phosphate binder (PB) pill burden, and laboratory parameters were evaluated during the four consecutive 91-day intervals of SO treatment.

Results
The mean age of the 402 patients who completed 1 year of SO was 55.2 years at baseline, and they had been on PD for an average of 19.9 months. SO was initiated with no baseline PB recorded in 36.1% of patients, whereas the remaining 257 patients were switched to SO from sevelamer (39.7%), calcium acetate (30.4%), lanthanum (1.2%), ferric citrate (14.0%), or more than one PB (14.8%). Mean sP at baseline was 6.26 mg/dL. After being prescribed SO, the percentage of patients achieving sP ≤ 5.5 mg/dL increased from 32.1% (baseline) to 46.5–54.0% during the 1-year follow-up, whereas the mean number of PB pills taken per day decreased from 7.7 at baseline (among patients on a baseline PB) to 4.6 to 5.4. Serum phosphorus and PB pill burden decreased regardless of changes in residual kidney function over the 12-month period. Similar results were observed for the full cohort (976 patients who either completed or discontinued SO during the 1-year follow-up).

Conclusions
Patients on PD who were prescribed SO as part of routine care for phosphorus management experienced significant reductions in SP and PB pills per day and improvements in sP target achievement, suggesting the effectiveness of SO on SP management with a concurrent reduction in pill burden.
Genetic analysis of a family affected by congenital myasthenic syndrome due to a Novel mutation in the SLC5A7 gene
Authors: Tian Sheng , Sun Huan , Gao Fen-Fang , Zhang Kang , Nan Jing , Niu Mu , Jia Xiao , Xu Gang , Ge Wei 
Published: June 2024

Abstract
Background
Mutations in the SLC5A7 gene cause congenital myasthenia, a rare genetic disorder. Mutation points in the SLC5A7 gene differ among individuals and encompass various genetic variations; however, exon deletion variants have yet to be reported in related cases. This study aims to explore the clinical phenotype and genetic traits of a patient with congenital myasthenic syndrome due to SLC5A7 gene variation and those of their family members.

Case presentation
We describe a case of a Chinese male with congenital myasthenic syndrome presenting fluctuating limb weakness. Genetic testing revealed a heterozygous deletion mutation spanning exons 1–9 in the SLC5A7 gene. QPCR confirmed a deletion in exon 9 of the SLC5A7 gene in the patient’s mother and brother. Clinical symptoms of myasthenia improved following treatment with pyridostigmine.

Conclusion
Exons 1, 5, and 9 of the SLC5A7 gene encode the choline transporter’s transmembrane region. Mutations in these exons can impact the stability and plasma membrane levels of the choline transporter. Thus, a heterozygous deletion in exons 1–9 of the SLC5A7 gene could be the pathogenic cause for this patient. In patients exhibiting fluctuating weakness, positive RNS, and seronegativity for myasthenia gravis antibodies, a detailed family history should be considered, and enhanced genetic testing is recommended to determine the cause.

Published: June 2024

Abstract
Background
Although road traffic injuries and deaths have decreased globally, there is substantial national and sub-national heterogeneity, particularly in low- and middle-income countries (LMICs). Ghana is one of few countries in Africa collecting comprehensive, spatially detailed data on motor vehicle collisions (MVCs). This data is a critical step towards improving roadway safety, as accurate and reliable information is essential for devising targeted countermeasures.

Methods
Here, we analyze 16 years of police-report data using emerging hot spot analysis in ArcGIS to identify hot spots with trends of increasing injury severity (a weighted composite measure of MVCs, minor injuries, severe injuries, and deaths), and counts of injuries, severe injuries, and deaths along major roads in urban and rural areas of Ghana.

Results
We find injury severity index sums and minor injury counts are significantly decreasing over time in Ghana while severe injury and death counts are not, indicating the latter should be the focus for road safety efforts. We identify new, consecutive, intensifying, and persistent hot spots on 2.65% of urban roads and 4.37% of rural roads. Hot spots are intensifying in terms of severity and frequency on major roads in rural areas.

Conclusions
A few key road sections, particularly in rural areas, show elevated levels of road traffic injury severity, warranting targeted interventions. Our method for evaluating spatiotemporal trends in MVC, road traffic injuries, and deaths in a LMIC includes sufficient detail for replication and adaptation in other countries, which is useful for targeting countermeasures and tracking progress.
New Orleans school meal programs during the COVID-19 pandemic: challenges and innovations identified through qualitative interviews
Authors: Knapp Megan B. , Creveling Kristine , Washington Domonique , Ennin Naana , Numa Tiffany 
Published: June 2024

Abstract
Background
School meal programs are critical to reducing childhood food insecurity. This study identified challenges and innovations in school meal service in a disaggregated charter school system during COVID-19 in New Orleans, Louisiana.

Methods
Semi-structured qualitative key informant interviews were conducted with school officials and school food providers. Interviews were recorded, transcribed, and coded. Using an immersion-crystallization approach, patterns were identified.

Results
Nine participants described challenges and solutions/innovations in food service focused around five themes: food service, procurement and costs, staffing, communication and outreach, and collaborations and partnerships. Participants faced challenges in meal service logistics, procuring food and supplies, staffing shortages, timely communication, lack of city-wide coordination, and the need to rapidly shift operations due to an evolving pandemic. While the disaggregated system created challenges in a city-wide response, the decentralized system along with policy changes offered opportunities for flexibility and innovation in meal programs through new partnership and coordination between schools and community, development of new processes for food service and procurement, and diverse modes of communication.

Conclusion
These findings add to the understanding of challenges faced and innovations implemented to continue school meal programs in a disaggregated school system. Collaboration with community organizations, leveraging resources, coordinated communication, and policies allowing for flexibility were key to response and should be encouraged to build capacity and resiliency in emergencies. In future city-wide emergency preparedness planning efforts, school leaders and food providers should be included in the planning to ensure continued equitable food access for students.
Clinical significance of chronic bronchitis in different racial groups
Authors: Choi Joon Young , Yoo Kwang Ha , Jung Ki-Suck , Kim Victor , Rhee Chin Kook 
Published: June 2024

Abstract
Backgrounds
Limited data are available on racial differences in the clinical features of chronic bronchitis (CB) patients with chronic obstructive pulmonary disease (COPD). In this study, we aimed to compare clinical features among CB patients of different races. We also analyzed the clinical significance of CB, defined classically and based on the COPD Assessment Test (CAT), to validate the CAT-based definition.

Methods
We analyzed patient data extracted from the Korean COPD Subgroup Study (KOCOSS) cohort (2012–2021) and US Genetic Epidemiology of COPD (COPDGene) study (2008–2011). We compared clinical characteristics among CB and non-CB patients of three different races using two CB definitions.

Results
In this study, 3,462 patients were non-Hispanic white (NHW), 1,018 were African American (AA), and 1,793 were Asian. The proportions of NHW, AA, and Asian patients with CB according to the classic definition were 27.4%, 20.9%, and 10.7%, compared with 25.2%, 30.9%, and 23.0% according to the CAT-based definition, respectively. The risk of CB prevalence was highest in NHW and lowest in Asian COPD patients. Among all races, CB patients were more likely to be current smokers, have worse respiratory symptoms and poorer health-related quality of life (HrQoL), and to have decreased lung function and exercise capacity. Most of these characteristics showed similar associations with the outcomes between the two definitions of CB. A binominal regression model revealed that CB patients of all races had an increased risk of future exacerbations according to both CB definitions, except for Asian patients with classically defined CB.

Conclusions
The presence of CB was associated with worse respiratory symptoms, HrQoL, exercise capacity and lung function, and more exacerbations, regardless of race or CB definition. The CAT-based definition may be more useful for assessing the risk of future exacerbations in Asian COPD patients.
A balance focused biometric does not predict rehabilitation needs and outcomes following total knee arthroplasty
Authors: Lee Jonathan J. , Arora Prerna , Finlay Andrea K. , Amanatullah Derek F. 
Published: June 2024

Abstract
Background
Both length of hospital stay and discharge to a skilled nursing facility are key drivers of total knee arthroplasty (TKA)-associated spending. Identifying patients who require increased postoperative care may improve expectation setting, discharge planning, and cost reduction. Balance deficits affect patients undergoing TKA and are critical to recovery. We aimed to assess whether a device that measures preoperative balance predicts patients’ rehabilitation needs and outcomes after TKA.

Methods
40 patients indicated for primary TKA were prospectively enrolled and followed for 12 months. Demographics, KOOS-JR, and PROMIS data were collected at baseline, 3-months, and 12-months. Single-leg balance and sway velocity were assessed preoperatively with a force plate (Sparta Science, Menlo Park, CA). The primary outcome was patients’ discharge facility (home versus skilled nursing facility). Secondary outcomes included length of hospital stay, KOOS-JR scores, and PROMIS scores.

Results
The mean preoperative sway velocity for the operative leg was 5.7 ± 2.7 cm/s, which did not differ from that of the non-operative leg (5.7 ± 2.6 cm/s, p = 1.00). Five patients (13%) were discharged to a skilled nursing facility and the mean length of hospital stay was 2.8 ± 1.5 days. Sway velocity was not associated with discharge to a skilled nursing facility (odds ratio, OR = 0.82, 95% CI = 0.27–2.11, p = 0.690) or longer length of hospital stay (b = -0.03, SE = 0.10, p = 0.738). An increased sway velocity was associated with change in PROMIS items from baseline to 3 months for global07 (“How would you rate your pain on average?” b = 1.17, SE = 0.46, p = 0.015) and pain21 (“What is your level of pain right now?” b = 0.39, SE = 0.17, p = 0.025) at 3-months.

Conclusion
Preoperative balance deficits were associated with postoperative improvements in pain and function after TKA, but a balance focused biometric that measured single-leg sway preoperatively did not predict discharge to a skilled nursing facility or length of hospital stay after TKA making their routine measurement cost-ineffective.
Optimization of traction parameters for lumbar scoliosis
Authors: He Wei , Li Jia-Long , Wang Jia-Yu , He Da , Song Kai 
Published: June 2024

Abstract
Background
Scoliosis is a high incidence disease that endangers the physical and mental health of adolescents. Traction therapy, as a conservative treatment plan, is helpful to improve the recovery speed of patients by studying the influence of different traction factors on the therapeutic effect.

Methods
Based on the thin layer CT data of the lumbar spine of a 16-year-old patient with scoliosis, Mimics21.0 was used to extract the 3D digital model, and Geomagic Wrap2021 was used to perform the smooth surface. After that, SolidWorks was used to manually construct the structures, such as the intervertebral disc, and Ansys17.0 was used to add constraints, ligaments, and other features. Three-factor ANOVA was carried out after an orthogonal experiment that considered traction mode, traction angle, and traction force was finished.

Results
① A three-dimensional biomechanical model of lumbar scoliosis was created. ② The model’s correctness was confirmed by comparing it to the corpse and other finite element models, as well as by verifying it under a range of working settings. ③ Traction force (P = 0.000), traction angle (P = 0.000), the interaction between traction force and traction angle (P = 0.000), and the interaction between traction mode and traction angle (P = 0.045) were all significant. ④ The interaction between traction force and traction angle has the most significant effect on Cobb, and traction with a certain angle is better than traditional axial traction. ⑤ Traction mode is not significant, but the interaction between traction mode and traction angle is significant.

Conclusions
A certain angle of traction can aid in improving outcomes and the traction force can be suitably decreased in the clinical formulation of the traction plan. The uniformity of correcting effect is more favorable when higher fixation techniques like positive suspension or traction bed traction are used, as opposed to overhanging traction.
Qualitative and quantitative assessment of non-clear cell renal cell carcinoma using contrast-enhanced ultrasound
Authors: Zhang WeiPing , Wang JingLing , Chen Li , Shi Jiayu 
Published: June 2024

Abstract
Background
Non-clear cell renal cell carcinoma (nccRCC) represents a rare form of renal cell carcinoma (RCC) in the clinic. It is now understood that contrast-enhanced ultrasound (CEUS) exhibits diverse manifestations and can be prone to misdiagnosis. Therefore, summarizing the distinctive features of contrast-enhanced ultrasonography is essential for differentiation from ccRCC.

Objective
This study aims to evaluate the diagnostic efficacy of qualitative and quantitative CEUS in diagnosing nccRCC to enhance our understanding of this condition.

Methods
We conducted a retrospective analysis of 21 patients with confirmed nccRCC following surgery and assessed the characteristic conventional ultrasound and CEUS imaging features. The paired Wilcoxon signed-rank sum test was employed to compare differences in CEUS time-intensity curve (TIC) parameters between the lesions and the normal renal cortex.

Results
Routine ultrasound revealed the following primary characteristics in the 21 nccRCC cases: hypoechoic appearance (10/21, 47.6%), absence of liquefaction (18/21, 66.7%), regular shape (19/21, 90.5%), clear boundaries (21/21, 100%), and absence of calcification (17/21, 81%). Color Doppler flow imaging (CDFI) indicated a low blood flow signal (only 1 case of grade III). Qualitative CEUS analysis demonstrated that nccRCC predominantly exhibited slow progression (76.1%), fast washout (57%), uniformity (61.9%), low enhancement (71.5%), and ring enhancement (61.9%). Quantitative CEUS analysis revealed that parameters such as PE, WiAUC, mTTI, WiR, WiPI, WoAUC, WiWoAUC, and WOR in the lesions were significantly lower than those in the normal renal cortex (Z=-3.980, -3.563, -2.427, -3.389, -3.980, -3.493, -3.528, -2.763, P < 0.001, < 0.001, = 0.015, = 0.001, < 0.001, < 0.001, < 0.001, = 0.006). However, there were no significant differences in RT, TTP, FT, or QOF (all P > 0.05).

Conclusion
nccRCC exhibits distinctive CEUS characteristics, including slow progression, fast washout, low homogeneity enhancement, and ring enhancement, which can aid in distinguishing nccRCC from ccRCC.
Developing mental health curricula and a service provision model for clinical associates in South Africa: a Delphi survey of family physicians and psychiatrists
Authors: Moodley Saiendhra Vasudevan , Wolvaardt Jacqueline , Grobler Christoffel 
Published: June 2024

Abstract
Background
Clinical associates are a health professional cadre that could be utilised in mental health task sharing in South Africa but this is training dependent. The objectives of the study were to identify the potential curricula content, training sites, and teaching modalities for undergraduate and potential postgraduate clinical associate mental health training and to identify the tasks that they should perform based on these curricula.

Methods
We utilised the Delphi method to reach consensus on items with the panel comprising psychiatrists and family physicians. The first round questionnaire of the Delphi survey was developed based on a literature review and the results from earlier phases of the overall study. The survey was administered electronically and consisted of three rounds. Following both the first and second rounds, an updated questionnaire was constructed omitting the items on which consensus was reached. The questionnaire consisted primarily of nine-point scales with consensus based on 70% of participants rating 1,2,3 or 7,8,9.

Results
There were 26 participants in the first round with this number falling to 23 in later rounds. There was strong consensus on a training attachment to a mental health clinic at a community health centre (CHC) at undergraduate (96.2%) and postgraduate level (100%). Consensus was reached on the importance of training on the management of six categories of disorders at the undergraduate level and nine categories of disorders at the postgraduate level. Clerking patients as a teaching modality reached 100% consensus at both undergraduate and postgraduate levels. PHC clinics, CHCs and district hospitals reached consensus as appropriate settings for clinical associates to provide mental health services. In addition, GP practices and secondary hospitals reached consensus for those with postgraduate training. Consensus was reached on ten of the 21 listed tasks that could be performed based on undergraduate training and 20 of the 21 tasks based on a postgraduate qualification in mental health.

Conclusions
The Delphi panel’s recommendations provide a clear roadmap for enhancing mental health curricula for clinical associates, enabling their utilisation in mental health service provision. A future postgraduate mental health qualification for clinical associates would allow for expanded task sharing.
