ABSTRACT

BACKGROUND: Brace treatment is the most effective tool for avoiding curve progression in moderate adolescent idiopathic scoliosis and high adherence is required to achieve therapeutic success. Despite this, the compliance often is impaired by the concern about the psychological well-being of adolescents.

OBJECTIVE: This 36-month follow-up study investigated if the patients most adherent to brace treatment could report a stronger impairment in the quality of life and body image.

METHODS: 64 adolescents with idiopathic scoliosis responded to the Scoliosis Research Society-22 revised Patient Questionnaire at 12, 24, and 36 months after prescription of a TLSO rigid brace. Retrospectively, participants who wore a brace for more than 75% of the prescribed time were assigned to the good-compliance group (GC); the others formed the poor-compliance group (PC).

RESULTS: At 12 months the GC group showed higher scores in treatment satisfaction and at 36 months they did not differ from the PC group in the overall SRS-22r score. Moreover, they achieved a statistically significant improvement in the scoliosis severity, although they showed lower scores in the self-image domain.

CONCLUSION: In our patient’s cohort, increased brace adherence does not compromise QoL and provides better treatment outcomes. However, more attention is needed to maintain good self-perception.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a respiratory disease caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and also affects the musculoskeletal system.

OBJECTIVE: This study was conducted to investigate the musculoskeletal symptoms, type of pain and effect on quality of life in patients presenting with pain after COVID-19.

METHODS: This prospective, descriptive study included 97 patients aged 18 years or older who were diagnosed with COVID-19 based on a positive polymerase chain reaction test result, with or without musculoskeletal pain prior to COVID-19 infection. Patients who applied to the post-COVID-19 outpatient clinic with the complaint of pain at least 1 month and maximum 1 year after the diagnosis of COVID-19 were included. Patients’ demographic characteristics and musculoskeletal examination findings were evaluated. The patients were examined, and the questionnaire forms were completed. The pain was assessed using the visual analog scale (VAS), the Douleur-Neuropathique-4 (DN-4) questionnaire, while the quality of life was assessed using the Short Form-36 (SF-36) survey. Patients were divided into groups in terms of gender, age, body mass index. Shapiro-Wilk’s test, the independent samples t-test and the Mann-Whitney U test were used for statistical analyses.

RESULTS: The mean age of the patients was 46.5 ± 13.5 years, 30 of them were male. Pain increased in patients with pre-COVID-19 arthralgia and myalgia (p< 0.001). Post-COVID-19 VAS was significantly higher than pre-COVID-19 VAS (7 ± 1.2 vs. 3.2 ± 1.9, p< 0.05). Pre-COVID-19 patients with myalgia had significantly worse SF-36 physical function, social function, pain, general health perception (p< 0.05). The mean scores of females in the SF-36 physical function, pain were significantly worse than males (p< 0.05). According to DN-4, 41 (42.3%) patients had neuropathic pain. There was moderate negative correlation between VAS, DN-4 and SF-36 (p< 0.05).

CONCLUSIONS: Arthralgia, myalgia, and neuropathic pain, all of which negatively affect the quality of life, are often observed in the patients infected with COVID-19.

ABSTRACT

BACKGROUND: Based on electromyography measurements, shoulder vibratory exercises efficiently stimulate shoulder muscles activity. Yet very few studies have supported that shoulder vibratory exercises increased shoulder muscles strength and function, and the noninferiority compared with conventional elastic resistance exercises remains unknown.

OBJECTIVE: This study investigated the effect of vibratory exercises versus conventional elastic resistance exercises with elastic bands on shoulder external rotation muscles strength and functional performance in young adults.

METHODS: 26 young adults (7 males and 19 females, with age 23.89 ± 3.02) were recruited and randomly allocated to shoulder vibratory exercises with FLEXI-BAR (FLEXI-BAR group) or conventional resistance exercises with elastic band (TheraBand group) for 3 times/week, 4 weeks totally. Shoulder external rotator muscles strength test and Underkofler softball distance throw test (USDTT) were performed before and after the training period.

RESULTS: After 4 weeks training, shoulder external rotator muscles strength increased 22.25 ± 15.06 N (P= 0.004, effect size = 1.48) within FLEXI-BAR group and 22.81 ± 14.94 N (P= 0.007, effect size = 1.53) within TheraBand group. There were no statistically significant differences between groups in the three muscle strength tests (P> 0.65). Regarding shoulder function, FLEXI-BAR exercises increased the throw distance 0.81 ± 0.92 meters in USDTT (P= 0.041, effect size = 0.88) while TheraBand exercise did not (P= 0.284), yet there was no statistically significant between group effects (P= 0.608).

CONCLUSIONS: These findings suggest that shoulder vibratory exercises can improve shoulder muscles strength in young adults and can be a useful alternative to the conventional elastic resistance exercises to improve the shoulder muscles strength and function. This provides therapists with more options in terms of choosing training equipment for rehabilitation programs.

ABSTRACT

BACKGROUND: In recent years, percutaneous kyphoplasty (PKP) has been increasingly used in clinical settings.

OBJECTIVE: In this study, we aimed to determine the analgesic effect of intravertebral lidocaine injections in PKP.

METHODS: A total of 60 patients who were treated with PKP were enrolled in this study. Lidocaine hydrochloride was chosen as the medication for the experimental group. Patients were randomly assigned into three groups using a double-blind study design: In group A (20 cases), no drugs were injected into the vertebral body during surgery; group B (20 cases) received intravertebral injection of normal saline; and in group C (20 cases), lidocaine hydrochloride was administered into the vertebral body during surgery. The age of patients, operation time, balloon dilatation pressure, balloon dilatation volume, and amount of bone cement injected were compared across the three groups. A pain visual analog scale (VAS) was used to assess pain suffered by the patients before, during, and 24 hours after the surgery.

RESULTS: Age, operation time, balloon dilatation pressure, balloon dilatation volume, and amount of bone cement injected did not differ significantly among the three groups (P> 0.05). The differences in VAS scores 24 hours before and after surgery were not statistically significant (P> 0.05). Group C had lower intraoperative VAS scores than groups A and B, and the difference was statistically significant (P< 0.01). There was no statistically significant difference between group A and group B (P> 0.05).

CONCLUSION: Intravertebral injections of lidocaine during PKP can successfully reduce intraoperative pain.

ABSTRACT

BACKGROUND: Sarcopenia is a common geriatric disease. Many dietary factors may contribute to the development of sarcopenia. Few studies have been conducted on dietary diversity and sarcopenia in Chinese older adults. Among a nationwide sample, the objective of this study is to assess the association between the dietary diversity score (DDS) and the prevalence of possible sarcopenia. We considered the different patterns of dietary diversity in relation to possible sarcopenia.

METHODS: We conducted this analysis utilizing the cross-sectional data from the 2012, 2014, and 2018 waves of the Chinese longitudinal healthy longevity survey (CLHLS). A standard developed by the Asian Working Group for Sarcopenia 2019 (AWGS2019) was used to assess the possibility of sarcopenia. On the basis of the DDS generated by previous studies, we have constructed four new indicators as follows: total diet, animal-based diet, plant-based diet, and plant-based diet without the consumption of legume products and nuts. We used the generalized estimation equation (GEE) model to evaluate the associations between the DDS of the total diet, animal-based diet, plant-based diet, and plant-based diet without the intake of legume products and nuts and possible sarcopenia. These associations were statistically adjusted for a variety of potential confounders. Sensitivity analysis was performed by excluding some participants who were long-term bedridden, had Alzheimer’s disease, or were terminally ill.

RESULTS: The analysis included 6,624 participants (mean age 83.4 years at baseline). In our study, we found that participants with a higher DDS of the total diet (OR = 0.62; 95% CI: 0.51-0.77), animal-based diet (OR = 0.62; 95% CI: 0.49-0.79), and plant-based diet (OR = 0.64;95% CI: 0.51-0.80) were at a lower risk of developing sarcopenia. In sensitivity analyses, the associations remained unchanged.

CONCLUSION: Taking a diversified diet, including animal foods, may reduce the risk of developing sarcopenia. According to the findings of this study, adopting a diversified diet might reduce the risk of sarcopenia for older adults.

ABSTRACT

BACKGROUND: Human monkeypox (mpox) disease is a multicountry outbreak driven by human-human transmission which has resulted in an international public health emergency. However, there is limited evidence on the positivity rate of skin lesions for mpox viral DNA. We aim to fill this gap by estimating the pooled positivity rate of skin samples with mpox viral DNA from mpox patients globally.

METHODS: In this systematic review and meta-analysis, seven databases and several preprint servers have been extensively searched until 17 January 2023 according to a prospectively registered protocol (PROSPERO: CRD42023392505). Articles including the positivity rate of skin samples with mpox viral DNA in mpox-confirmed patients were considered eligible. After a quality assessment, a random-effect meta-analysis was used for pooled prevalence. To explore and resolve heterogeneity, we used statistical methods for outlier detection, influence analysis, and sensitivity analysis.

FINDINGS: Among the 331 articles retrieved after deduplication, 14 studies were finally included. The pooled positivity rate of the skin samples was 98.77% (95% CI: 94.74%-99.72%). After the removal of an influential outlier, I ² for heterogeneity dropped from 92.5% to 10.8%. Meta-regression did not reveal any significant moderator.

CONCLUSION/INTERPRETATION: The present findings reinforce that skin lesions act as a reservoir of mpox viral DNA and contribute to a high infectivity risk. This may be a prevailing basis of prompt transmission during the current multicountry outbreak and also needs further investigation. The present imperative outcome may benefit in producing valuable preventive and management procedures in an appropriate health strategy.

ABSTRACT

This study aimed to design an anatomical contour metal three-dimensional (3D)-printed oblique lateral lumbar interbody fusion (OLIF) cage with porous (lattices) structure and embedded screw fixation to enhance bone ingrowth to reduce the risk of cage subsidence and avoid the stress-shielding effect. Finite element (FE) analysis and weight topology optimization (WTO) were used to optimize the structural design of the OLIF cage based on the anatomical contour morphology of patients with osteoporosis. Two oblique embedded fixation screws and lattice design with 65% porosity and average pore size of 750 μm were equipped with the cage structure. The cage was fabricated via metal 3D printing, and static/dynamic compression and compressive-shear tests were performed in accordance with the ASTM F2077-14 standard to evaluate its mechanical resistance. On FE analysis, the OLIF cage with embedded screw model had the most stability, lowest stress values on the endplate, and uniform stress distribution versus standalone cage and fixed with lateral plate under extension, lateral flexion, and rotation. The fatigue test showed that the stiffnesses/endurance limits (pass 5 million dynamic test) were 16,658 N/mm/6000 N for axial load and 19,643 N/mm/2700 N for compression shear. In conclusion, an OLIF cage with embedded fixation screws can be designed by integrating FE and WTO analysis based on the statistical results of endplate morphology. This improves the stability of the OLIF cage to decrease endplate destruction. The complex contour and lattice design of the OLIF cage need to be manufactured via metal 3D printing; the dynamic axial compression and compressive-shear strengths are greater than that of the U.S. Food and Drug Administration (FDA) standard.

ABSTRACT

Introduction: Klotho is a protein associated with protection from aging-related diseases and health conditions. Obesity is associated with lower Klotho concentrations. Thus, this secondary analysis of adults with obesity examined 1) the change in serum Klotho concentration in response to a behavioral weight loss intervention by the magnitude of weight loss achieved; and 2) the association among serum Klotho concentration and weight, body composition, and cardiorespiratory fitness. Methods: Participants were randomized to either diet alone (DIET), diet plus 150 min of physical activity per week (DIET + PA150), or diet plus 250 min of physical activity per week (DIET + PA250). Participants [n = 152; age: 45.0 ± 7.9 years; body mass index (BMI): 32.4 ± 3.8 kg/m²] included in this secondary analysis provided blood samples at baseline, 6-, and 12 months, and were classified by weight loss response (Responder: achieved ≥10% weight loss at 6 or 12 months; Non-responder: achieved <5% weight loss at both 6 and 12 months). Serum Klotho was measured using a solid-phase sandwich enzyme-linked immunosorbent assay (ELISA). Analyses of covariance (ANCOVA’s) were used to examine changes in weight, body composition, cardiorespiratory fitness, and Klotho concentration by weight loss response across the 12-month weight loss intervention. Results: Responders had a greater reduction in measures of weight and body composition, and a greater increase in cardiorespiratory fitness, compared to Non-Responders (p < 0.05). Change in Klotho concentration differed between Responders and Non-Responders (p < 0.05), with the increase in Klotho concentration from baseline to 6 months for Responders being statistically significant. The 6-month change in Klotho concentration was inversely associated with the 6-month change in weight (r _s = -0.195), BMI (r _s = -0.196), fat mass (r _s = -0.184), and waist circumference (r _s = -0.218) (p-values <0.05). Discussion: Findings provide evidence within the context of a behavioral intervention, with and without exercise, that change in Klotho concentration is significantly different between adults with weight loss ≥10% compared to <5% across 12 months. These findings suggest that weight loss and reduction in fat mass may be favorably associated with the change in Klotho concentration. This may reduce the risk of negative health consequences associated with accelerated aging in middle-aged adults.

ABSTRACT

The Surviving Sepsis Campaign Guidelines recommend fluid administration of 30 cc/kg ideal body weight (IBW) for patients with sepsis and lactate greater than 4 mmol/L within 3 hours of identification. In this study, we explore the impact of fluid dose on lactate normalization, treatment cost, length of stay, and mortality in patients with lactate greater than 4.

DESIGN: Multicenter retrospective observational study.

SETTING: Eight-hospital urban healthcare system in Northeastern United States.

PATIENTS: Patients with sepsis, initial lactate value greater than 4 mmol/L, and received appropriate antibiotics within 3 hours.

INTERVENTIONS: None.

MEASUREMENTS AND MAIN RESULTS: We stratified patients into five groups based on the dose of fluid administered within 3 hours after sepsis identification. The groupings were less than 15 cc/kg IBW, 15.1-25 cc/kg IBW, 25.1-35 cc/kg IBW, 35.1-50 cc/kg IBW, and greater than 50 cc/kg IBW. We used the group that received a fluid dose of 25.1-35 cc/kg IBW, as a reference group. The mean age was 66 years, and 56% were male. Three hundred seventy-one (25%) received less than 15 cc/kg of IBW of crystalloid fluid, 278 (17%) received 15-25 cc/kg of IBW, 316 (21%) received 25.1-35 cc/kg of IBW, 319 (21%) received 35.1-50 cc/kg of IBW, and 207 (14%) received greater than 50 cc/kg of IBW. After multilinear regression, there was no significant difference in lactate normalization between the reference group and any of the other fluid groups. We also found no statistically significant difference in the observed/expected cost, or observed/expected length of stay, between the reference group and any of the other fluid groups. Mortality was higher among patients who received greater than 50 cc/kg IBW when compared to the recommended dose.

CONCLUSIONS: In patients with sepsis and lactate value greater than 4 mmol/L, high or low fluid doses were not associated with better lactate clearance or patient outcomes. Greater than 50 cc/kg IBW dose of fluids within 3 hours is associated with higher mortality.

ABSTRACT

Objective: To investigate the value of contrast-enhanced ultrasound in detecting endoleak after endovascular repair of infrarenal abdominal aortic aneurysm (EVAR). Methods: The postoperative follow-up data of 102 patients with infrarenal abdominal aortic aneurysm treated with EVAR in Tianjin Medical University General Hospital from August 2015 to December 2021 were retrospectively analyzed. There were 79 males and 23 females, aged 50-91 (69.6±7.6) years old. Using CT angiography (CTA) as the gold standard for diagnosing endoleaks, the effectiveness of contrast-enhanced ultrasound and CDUS in detecting endoleaks was evaluated by paired design chi-square test, and the Kappa value was calculated for consistency test. Patients were divided into groups according to body mass index (BMI), and the number of false-negative endoleaks detected by contrast-enhanced ultrasound in each group was calculated, and its ratio to the actual number of endoleaks was calculated to evaluate whether BMI was related to false-negative ultrasound-enhanced ultrasound. Results: A total of 203 follow-up visits met the inclusion criteria. Endoleaks were detected 36 times (17.7%) by CTA, 31 times (15.3%) by contrast-enhanced ultrasound, 16 times (7.9%) by CDUS, and they all detected type Ⅰ, type Ⅱ and type Ⅲ endoleaks. There was no significant difference between contrast-enhanced ultrasound and CTA in endoleak detection rate and determination of endoleak types (endoleak detection rate: 15.3% vs 17.7%; determination of endoleak types: type Ⅰ 4 vs 4, type Ⅱ 26 vs 31, type Ⅲ 1 vs 1; all P>0.05). CDUS and CTA had statistically significant differences in the detection rate of endoleaks and determination of endoleak types (endoleak detection rate: 7.9% vs 17.7%; determination of endoleak types: type Ⅰ 4 vs 4, type Ⅱ 11 vs 31, type Ⅲ 1 vs 1; all P<0.001). Compared with CTA, contrast-enhanced ultrasound has a sensitivity of 83.3%, a specificity of 99.4%, a Youden index of 0.827, a coincidence rate of 96.6%, a positive predictive value of 96.8%, a negative predictive value of 96.5%, and a Kappa value of 0.875(P<0.001). The two showed excellent diagnostic consistency. All 6 endoleaks not detected by contrast-enhanced ultrasound were type Ⅱ endoleak that did not require treatment, and 3(15.8%) occurred in obese patients with a BMI≥32 kg/m². Compared with CTA, CDUS had a sensitivity of 38.9%, a specificity of 98.8%, a Youden index of 0.377, a coincidence rate of 88.2%, a positive predictive value of 87.5%, a negative predictive value of 88.2%, and a Kappa value of 0.482 (P<0.001). The two showed moderate diagnostic agreement. The correlation coefficient of the maximum diameter of aneurysms measured by ultrasound and CT was r=0.873(P<0.001). Conclusions: Contrast-enhanced ultrasound is accurate in detecting endoleak after infrarenal EVAR, and its sensitivity to endoleak detection in obese patients with BMI≥32 kg/m² will be reduced. CDUS is not suitable for detection of endoleak after infrarenal EVAR, but it can be used to monitor the change of the largest diameter of aneurysm after EVAR.
