ABSTRACT

OBJECTIVE: Gamma Knife radiosurgery (GKRS) is a treatment option for refractory trigeminal neuralgia (TN). However, there is a paucity of data regarding the effectiveness of GKRS for relapsing TN following microvascular decompression (MVD). The aim of this study was to characterize the response rate, complications, pain relief durability, and predictors of pain relapse for salvage GKRS following MVD for TN.

METHODS: A retrospective study of all patients who received GKRS for Burchiel type 1 TN (TN1) or type 2 TN (TN2) pain at Wake Forest University School of Medicine was conducted. Pain was measured using the Barrow Neurological Institute (BNI) pain intensity score. After an initial pain response of BNI scores I-III, a BNI score of IV or V constituted relapse. Durability of pain relief was characterized using the Kaplan-Meier estimator. Predictors of relapse were investigated using Cox regression models. Statistical significance was set at p < 0.05.

RESULTS: Of 2065 patients with TN1 or TN2, 59 had GKRS post-MVD. Forty-nine (83.1%) of these patients experienced a BNI pain score of I-III at the first follow-up post-GKRS. The median time to relapse was 1.75 years; freedom rates from relapse were 77%, 45.9%, and 30.7% at 1, 2, and 5 years, respectively. Radiofrequency ablation prior to MVD significantly decreased the likelihood of an initial response to salvage GKRS (Fisher’s exact test, p = 0.02). After controlling for baseline and clinical characteristics, facial numbness significantly decreased the likelihood of pain relapse (Cox regression, HR 0.15, 95% CI 0.03-0.73; p = 0.01). Conversely, a worse initial pain response significantly increased the likelihood of pain relapse (Cox regression, HR 3.64, 95% CI 1.02-12.95; p = 0.04). Pain relapse within 24 months of the original MVD did not predict durability of pain relief following salvage GKRS (Cox regression, HR 0.94, 95% CI 0.40-2.22; p = 0.89). The overall toxicity rate of salvage GKRS was 35.6%.

CONCLUSIONS: Salvage GKRS presents an effective, noninvasive option for recurring TN after MVD, with a comparable response rate to primary GKRS or MVD, and a favorable complications profile relative to salvage MVD. Patients with postoperative facial numbness and a better initial pain response may experience more durable pain relief following salvage GKRS.

ABSTRACT

OBJECTIVE: Instrumentation surgery in combination with radiotherapy (RT) is one of the key management strategies for patients with spinal metastases. However, the use of materials can affect the RT dose delivered to the tumor site and surrounding tissues, as well as hinder optimal postoperative tumor evaluation. The association of the preoperative Spine Instability Neoplastic Score (SINS) with the need for spinal stabilization and life expectancy are unclear. This multicenter prospective study aimed to investigate the current situation and make recommendations regarding the choice of surgical procedure based on the preoperative SINS and prospectively collected postoperative patient-reported outcomes (PROs).

METHODS: The study prospectively included 317 patients with spinal metastases who underwent palliative surgery and had a minimum follow-up period of 6 months. The survey items included SINS, patient background, and clinical data including surgical procedure, history of RT, prognosis, and PROs (i.e., the visual analog scale score, Faces Scale, Barthel Index, Vitality Index, and 5-level EQ-5D health survey) at baseline, and at 1 and 6 months after surgery. The association of preoperative SINS with life expectancy, PROs, and surgical procedures was examined using statistical analysis.

RESULTS: Preoperative SINS (three categories) had no association with life expectancy. All PROs evaluated in the study improved up to 6 months after surgery. Pain categories (visual analog scale score and/or Faces Scale) at baseline were correlated with preoperative SINS. As many as 90.9% of enrolled patients underwent fusion surgery, and even in SINS 0-6 cases, implants were used in 64.3% of patients. Postoperative RT was performed in 42.9% of the patients. However, prospective assessments of PROs showed no significant difference between surgical procedures (with and without fusion) in patients with SINS 0-9. In addition, no cases required conversion from noninstrumentation surgery to fusion surgery.

CONCLUSIONS: Although the choice of surgical procedure should be made on a case-by-case basis on the NOMS (neurological, oncological, mechanical, and systemic) framework, careful consideration is required to determine whether spinal stabilization is needed in patients with SINS ≤ 9, considering the patient’s background and the plan for postoperative adjuvant therapy.

ABSTRACT

BACKGROUND: Interdisciplinary evaluation of older adults’ health care is a priority in the prevention of chronic health conditions and maintenance of daily functioning. While many studies evaluate different physical performance tests (PPTs) from a retrospective view in predicting mortality or cardiopulmonary health, it remains unclear which of the commonly used PPTs is the most effective at evaluating the current health of older adults. Additionally, the time and participant burden for each PPT must be considered when planning and implementing them for clinical or research purposes.

OBJECTIVE: This cross-sectional study aimed to determine how elements of overall physical capacity, performance, and other nongait factors in older adults affect the results of 3 commonly used tests: the Short Physical Performance Battery (SPPB), 6-minute walk test (6MWT), and Incremental Shuttle Walk Test (ISWT).

METHODS: A total of 53 community-dwelling older adults met the inclusion and exclusion criteria (mean age 77.47, SD 7.25 years; n=41, 77% female; and n=21, 40% Hispanic). This study evaluated older adults using 3 different PPTs including the SPPB, 6MWT, and ISWT, as well as constructed multiple linear regression models with measures of physical activity, static balance, and fear of falling (FoF). The nongait measures included 7 days of physical activity monitoring using the ActiGraph GT9X Link instrument, objective measurement of static balance using the BTrackS Balance System, and FoF using the short Fall Efficacy Scale-International.

RESULTS: The models revealed that the complete SPPB provided the most comprehensive value, as indicated by a greater R² value (0.523), and that performance on the SPPB was predicted by both moderate to vigorous physical activity (P=.01) and FoF (P<.001). The ISWT was predicted by moderate to vigorous physical activity (P=.02), BMI (P=.02), and FoF (P=.006) and had a similar R² value (0.517), whereas the gait component of the SPPB (P=.001) and 6MWT (P<.001) was predicted by only FoF and had lower R² values (0.375 and 0.228, respectively).

CONCLUSIONS: The results indicated the value of a multicomponent, comprehensive test, such as the SPPB, in evaluating the health of older adults. Additionally, a comparison of the 2 field walking tests (ISWT and 6MWT) further distinguished the ISWT as more responsive to overall health in older adults. In comparing these commonly used PPTs, clinicians and researchers in the field can determine and select the most optimal test to evaluate older adults in communities and research settings.

ABSTRACT

BACKGROUND: Smart glasses have emerged as a promising solution for enhancing communication and care coordination among distributed medical teams. While prior research has explored the feasibility of using smart glasses to improve prehospital communication between emergency medical service (EMS) providers and remote physicians, a research gap remains in understanding the specific requirements and needs of EMS providers for smart glass implementation.

OBJECTIVE: This study aims to iteratively design and evaluate a smart glass application tailored for prehospital communication by actively involving prospective users in the system design process.

METHODS: Grounded in participatory design, the study consisted of 2 phases of design requirement gathering, rapid prototyping, usability testing, and prototype refinement. In total, 43 distinct EMS providers with diverse backgrounds participated in this 2-year long iterative design process. All qualitative data (eg, transcribed interviews and discussions) were iteratively coded and analyzed by at least 2 researchers using thematic analysis. Quantitative data, such as System Usability Scale (SUS) scores and feature ratings, were analyzed using statistical methods.

RESULTS: Our research identified challenges in 2 essential prehospital communication activities: contacting online medical control (OLMC) physicians for medical guidance and notifying receiving hospital teams of incoming patients. The iterative design process led to the identification of 5 key features that could potentially address the identified challenges: video call functionality with OLMC physicians, call priority indication for expedited OLMC contact, direct communication with receiving hospitals, multimedia patient information sharing, and touchless interaction methods for operating the smart glasses. The SUS score for our system design improved from a mean of 74.3 (SD 11.3) in the first phase (classified as good usability) to 80.3 (SD 13.1) in the second phase (classified as excellent usability). This improvement, along with consistently high ratings for other aspects (eg, willingness to use and feature design), demonstrated continuous enhancement of the system’s design across the 2 phases. Additionally, significant differences in SUS scores were observed between EMS providers in urban areas (median 85, IQR 76-94) and rural areas (median 72.5, IQR 66-83; Mann-Whitney U=43; P=.17), as well as between paramedics (median 72.5, IQR 70-80) and emergency medical technicians (median 85, IQR: 74-98; Mann-Whitney U=44.5; P=.13), suggesting that EMS providers in urban settings and those with less training in treating patients in critical conditions perceived the smart glass application as more useful and user-friendly. Finally, the study also identified several concerns regarding the adoption of the smart glass application, including technical limitations, environmental constraints, and potential barriers to workflow integration.

CONCLUSIONS: Using a participatory design approach, this study provided insights into designing user-friendly smart glasses that address the current challenges EMS providers face in dynamic prehospital settings.

ABSTRACT

BACKGROUND: Rhinosinusitis (RS), a common inflammatory disorder, adversely affects quality of life and can progress to serious complications without intervention. Conventional therapies, including antibiotics and corticosteroids, exhibit inherent limitations and risks. Traditional Chinese medicine (TCM), with its extensive historical use in RS management, remains understudied in contemporary evaluations. This systematic review evaluates the efficacy and safety of TCM in RS treatment, aiming to guide clinical decision-making.

METHODS: A systematic search was undertaken in Chinese and English databases, such as CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, Web of Science, and other relevant databases, to gather randomized controlled trials of TCM for patients with RS from January 2014 to February 2024. Two researchers independently curated and synthesized data from eligible literature, conducted meta-analyses with ReviewManager 5.4.1, and assessed evidence quality via GRADEPro GDT.

RESULTS: A total of 48 articles included 4490 patients, of which 2249 were control group and 2241 were in the experimental group. Meta-analytic outcomes revealed that the integration of TCM with western medicine conventional treatment significantly enhanced the total effective rate [risk ratio=1.20, 95% confidence interval (CI) (1.17, 1.23), P < 0.05] and yielded a notable reduction in Lund-Kennedy score [mean difference (MD)=-1.32, 95% CI (-1.72, -0.93), P < 0.05], Lund-Mackay score [MD=-1.13, 95% CI (-1.27, -1.00), P < 0.05], SNOT-20 score [MD=-3.02, 95% CI (-4.34, -1.69), P < 0.05], nasal congestion Visual Analogue Scale (VAS) score [MD=-1.05, 95% CI (-1.65, -0.45), P < 0.05], runny nose VAS score [MD=-0.84, 95% CI (-1.13, -0.54), P < 0.05], headache VAS score [MD=-0.90, 95% CI (-1.45, -0.35), P < 0.05], olfactory impairment VAS score [MD=-1.43, 95% CI (-1.75, -1.11), P < 0.05], and total TCM syndrome score [standardized mean difference (SMD)=-1.78, 95% CI (-2.58, -0.97), P < 0.05]. Additionally, significant decreases were observed in levels of tumor necrosis factor-α [SMD=-2.14, 95% CI (-3.42, -0.87), P < 0.05] and interleukin-6 [SMD=-1.64, 95% CI (-2.08, -1.21), P < 0.05], with statistical significance achieved for all measured outcomes. Regarding safety considerations, an insignificant variance was observed between the 2 therapeutic approaches, with no statistically discernible difference (P > 0.05).

CONCLUSION: Combining TCM with western medicine in RS treatment yields superior outcomes over western medicine alone, with enhanced efficacy, reduced nasal symptoms, and lower inflammation. Rigorous multicenter RCTs are warranted to affirm these advantages and bolster the evidence for TCM in RS management.

ABSTRACT

A typical surgical technique for pregnant women with potentially fatal problems affecting the mother or fetus is an emergency cesarean section (ECS). The decision-to-delivery interval (DDI) for ECS should be within 30 minutes. The objective of this study was to investigate crash ECS indications and effects on maternal and neonatal outcomes. In this retrospective study, all women undergoing crash cesarean section (CS) at Obstetrics and Gynecology department at King Abdulaziz University hospital, Jeddah, Saudi Arabia during 2022 and 2023 were evaluated. Data about demographic and obstetric characteristics of mother, ECS indications, DDI, and outcomes for mothers and newborns was gathered from the patient’s sheet. One hundred 3 crash CS were performed during study period. Crash CS indications were fetal bradycardia (64.1%), prolapsed cord (24.3%), uterine rupture (6.8%), and severe antepartum hemorrhage (4.9%). D-D time range from 2 to 30 minutes. DDI was ≤15 minutes in 90 patients (87.4%) and >15 minutes in 13 patients (12.6%). Gestational age was <32 weeks (16.7%), between 32 and <37 weeks (15.5%), and ≥37 weeks (68.0%). Good maternal outcome was reported in 89 (86.4%), while 24 (13.6%) had complications. Intensive care unit maternal admission was significantly higher in gestational age 32 to <37 weeks versus <32 weeks and ≥37 weeks of gestation (18.8% vs 5.9% and 2.9%, P = .050). Fetal outcome was good in 69 (67.0%), while 34 (33.0%) had complications. Neonatal body weights, Apgar score at 1, 5, 10 minutes, and umbilical cord arterial pH were significantly decreased in preterm versus termed neonates (P < .0001, P < .0001, P < .0001, P = .014, and P = .003). Moreover, respiratory distress syndrome, jaundice, intubation, neonatal deaths, and sepsis were significantly higher in preterm versus term deliveries (P < .0001, P = .029, P < .0001, P = .010, and P = .031). Good neonatal outcome was significantly higher (P < .0001); while respiratory distress syndrome was significantly lower (P = .007) in deliveries with DDI ≤ 15 minutes versus > 15 minutes. The 30-minute standard for DDI time interval may be a feasible guideline at least for level-3 hospitals. Crash CS indication was mostly due to fetal bradycardia. The maternal and neonatal outcomes were better in term than preterm deliveries. The positive effect of very short intervals on neonatal outcome still needs to be proven.

ABSTRACT

Evidence suggests a strong association between prostate diseases, lower urinary tract symptoms (LUTS), and pro-inflammatory diets. Our study was conducted to assess the relationship between the Dietary Inflammatory Index (DII) and prostate diseases, LUTS using the 2003 to 2008 U.S. National Health and Nutrition Examination Survey (NHANES) database. After the chi-square test to investigate whether demographic data and prostate diseases, LUTS were correlated, for positive results, we performed weighted multivariable logistic regression models analysis. In addition, we performed nonlinear tests using restricted cubic spline (RCS) and assessed the stability between different subgroups by subgroup and interaction analyses. The study included 30,619 subjects. After adjusting the regression model for fully confounding variables, DII was only correlated with benign prostatic hyperplasia (BPH) (OR = 1.074, 95% CI = 1.016-1.136; P = .012). And, the RCS relationship between DII and BPH was positively correlated (nonlinear: P = .830). We did not find statistically significant interactions in all subgroups. At the same time, we did not find any correlation between DII and other prostate diseases and LUTS. Pro-inflammatory diets are associated with an increased risk of BPH. Dietary modifications to reduce the intake of pro-inflammatory nutrients can be helpful in mitigating the development of BPH.

ABSTRACT

BACKGROUND: This study aimed to assess the impact of the timing of low-dose hydrocortisone adjuvant therapy initiation on clinical outcomes in patients with septic shock by a systematic review and meta-analysis.

METHODS: We conducted a comprehensive search of all randomized controlled trials (RCTs) and cohort studies available in the PubMed, Web of Science, and Embase databases. The search included articles published from the founding of these databases until August 1, 2024. The purpose of the search was to compare the results of initiating low-dose hydrocortisone (HC) adjuvant therapy at different time periods. The main reported results included short-term mortality (ICU mortality and hospital mortality) as key outcomes, and secondary outcomes such as the rate of renal replacement treatment continuous renal replacement therapy (CRRT), length of stay in the intensive care unit (ICU), and rate of shock reversal.

RESULTS: Seven trials, with a total of 3063 patients, were included. The main finding of this meta-analysis indicates that the early treatment group, which received low-dose hydrocortisone, had a lower ICU mortality rate compared to the late treatment group. Additionally, the hospital mortality rate in the early treatment group was lower than that in the late treatment group. There was a correlation between the timing of beginning of HC and the short-term mortality of patients with septic shock. The secondary findings indicated that there were no notable disparities in the rates of CRRT, the rate of reversing shock, and the duration of stay in the ICU.

CONCLUSION: Administering low doses of HC early on can decrease the risk of death in septic shock patients in the short-term mortality. There were no substantial disparities observed in the rate of CRRT, the rate of reversal of shock, and the duration of stay in the ICU. Additional extensive RCTs are required to validate this conclusion.

ABSTRACT

BACKGROUND: The association between polymorphisms in the ATP-binding cassette transporter A1 (ABCA1) gene and the risk of developing glaucoma has yielded conflicting results across various studies. This meta-analysis aims to comprehensively assess whether genetic variations in ABCA1 significantly contribute to the susceptibility to glaucoma.

METHODS: An extensive search was conducted across major databases, including PubMed, EMBASE, and the China National Knowledge Infrastructure (CNKI), covering all publications from the inception of each database through December 2023. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to quantify the strength of the association between ABCA1 polymorphisms and glaucoma risk.

RESULTS: A significant association was observed between ABCA1 gene polymorphisms and glaucoma risk in the overall analysis, as demonstrated by allele contrast (P < .001), homozygote comparison (P < .001), heterozygote comparison (P < .001), recessive genetic model (P = .017), and dominant genetic model (P < .001). Notably, these associations were particularly pronounced in the Asian population, with all models showing statistical significance (P < .05). However, no significant association was detected in Caucasian or mixed populations, suggesting a potential ethnic specificity in the genetic susceptibility to glaucoma conferred by ABCA1 polymorphisms.

CONCLUSIONS: Our findings indicate that ABCA1 polymorphisms may play a role in increasing the risk of glaucoma, specifically within Asian populations. This contrast highlights the importance of considering ethnic background in genetic association studies.

ABSTRACT

Chronic opioid use (COU) after traumatic injuries is a global health concern. COU after trauma delays recovery and increases the risk of long-term drug dependence. However, the population-prevalence and factors associated with COU after traumatic injury in South Korea remain unclear. We aimed to estimate the prevalence of COU and associated risk factors in patients after trauma in South Korea. A historical cohort study using the population-representative database including 1,103,405 South Korean subjects, patients admitted due to a newly diagnosed trauma (n = 65,444) or nontraumatic etiologies (n = 338,321) from January 1, 2003, to June 30, 2015, were analyzed. COU was defined as the prescription of opioid in the first 3 to 6 months from the index date. Prevalence of COU was summarized. A multivariable logistic regression analysis was conducted to investigate association of COU with traumatic injuries, accounting for a priori sociodemographic and clinical risk factors. A total of 13.5% and 12.6% of patients were found to be chronic opioid users in the trauma and the control group, respectively. The adjusted odds ratio (aOR) (95% CI) of COU in the injured compared to the noninjured was 1.13 (1.01 to 1.16), when controlling for age group, sex, calendar year, area of residence, previous opioid use, comorbidity, surgery during the index admission and intensive care unit care. Risk factors included being aged 65 to 74 years (aOR = 2.87; 95% CI = 2.73 to 3.01), aged ≥ 75 years (aOR = 2.48; 95% CI = 2.35 to 2.62), and history of previous opioid use (aOR = 3.27; 95% CI = 3.21 to 3.34) were the most significant risk factors of COU, independent of injury. COU was prevalent both in the injured and noninjured patients, with slightly increased risk of COU in those sustaining traumatic injury compared to those who were noninjured. Further stud y to address prevalent COU in South Korea is required to avoid opioid-related harms.
