ABSTRACT

BACKGROUND: The U.S.-Mexico “border wall” between El Paso, Texas and Ciudad Juárez, Mexico was raised and extended beginning in 2018 in accordance with Presidential Executive Order 13,767. We hypothesized that these changes resulted in increased incidence and severity of injuries of individuals attempting to cross the border wall in the El Paso region.

METHODS: A retrospective cohort review was conducted of University Medical Center of El Paso Trauma Registry charts from 2001 to 2022. Year of injury, gender, age, Injury Severity Score, hospital length-of-stay, ICU length-of-stay, ventilator days, and survival were analyzed by Chi-square analysis with Fisher’s exact test for categorical variables and Independent Samples T-test for continuous variables. An independent samples Mann Whitney U Test was used to compare border wall fall injuries before and after 2018.

RESULTS: Of the 842 patients reviewed, 69 patients presented before 2018 and 773 presented from 2018 to 2022. Statistically significant differences were identified in the mean Injury Severity Score which increased from 6.3 (SD ± 3.8) to 8.3 (SD ± 5.5, p < .001) and the mean hospital length-of-stay which increased from 6.7 days (SD ± 5.5) to 9.5 days (SD ± 8.0, p < .005).

CONCLUSION: The incidence, severity, and hospital length-of-stay related to injuries crossing the U.S.-Mexico border have increased with changes in height of the border wall since 2018. Additional resources should be allocated to Emergency Departments and Trauma Centers along the Southwest Border to serve this unique patient population. Additional consideration should be given to the cost of the border wall.

ABSTRACT

BACKGROUND: The triglyceride-glucose (TyG) index has garnered recognition as a surrogate marker for insulin resistance, a pivotal factor in the pathogenesis of various metabolic disorders. Despite its emerging role, the empirical evidence delineating its association with prediabetes mellitus (Pre-DM) remains scant. This research aims to clarify the link between the TyG index and the likelihood of Pre-DM development within a Chinese demographic.

METHODS: This investigation was structured as a retrospective cohort analysis, encompassing a sample of 179,177 Chinese adults. These individuals underwent medical examinations at the Rich Healthcare Group over a period spanning from 2010 to 2016. To ascertain the relationship between the TyG index and the incidence of Pre-DM, this study employed Cox regression analysis complemented by sensitivity and subgroup assessments. Furthermore, Cox proportional hazards regression with cubic spline functions and smooth curve fitting was incorporated to explore the existence of any non-linear connection within this association.

RESULTS: Upon adjusting for a comprehensive array of confounding variables, a statistically significant positive correlation between the TyG index and the risk of Pre-DM was identified (HR: 1.60, 95%CI 1.56-1.65, P < 0.001). The analysis illuminated a non-linear relationship, with an inflection point at a TyG index value of 8.78. For TyG index values below and above this inflection point, the HR was calculated to be 1.94 (95%CI 1.86-2.03) and 1.26 (95%CI 1.20-1.33), respectively. Sensitivity analyses further fortified the reliability of these findings.

CONCLUSIONS: This comprehensive examination delineated a significantly positive, non-linear correlation between the TyG index and the risk of Pre-DM within a Chinese population. Individuals with TyG index values below 8.78 have a significantly increased risk of developing prediabetes. These findings underscore the TyG index’s potential efficacy as a predictive tool for assessing Pre-DM risk in clinical practice.

ABSTRACT

OBJECTIVE: To explore the association between the Oxidative Balance Score (OBS), which represents the balance of multiple oxidative stress-related dietary and lifestyle exposures, and the risk of metabolic syndrome (MetS).

METHODS: A population-based cross-sectional study design was adopted and 16,850 participants in NHANES database were included in the statistics analysis stage. The OBS was constructed by combining information from 20 a priori selected pro- and antioxidant factors. Weighted logistic regression and restricted cubic splines (RCS) were used to estimate the association between OBS and MetS.

RESULTS: Participants in the highest OBS quartile, indicating low oxidative stress (OS) levels, exhibited a significantly lower risk of MetS (odds Ratio [OR] = 0.55, 95% confidence Interval [CI]: 0.47-0.64) compared to the lowest quartile. Specifically, higher OBS was inversely associated with abdominal obesity (OR = 0.61, 95% CI: 0.54-0.69), hypertension (OR = 0.69, 95% CI: 0.58-0.83), elevated triglycerides (OR = 0.68, 95% CI: 0.57-0.82), low high-density lipoprotein cholesterol (HDL-C) levels (OR = 0.60, 95% CI: 0.50-0.70) and fasting blood glucose (FBG) levels (OR = 0.74, 95% CI: 0.62-0.88). The observed inverse association between OBS and hypertension or FBG levels appeared to primarily influenced by BMI. The association between dietary OBS intervals and elevated FBG levels was not statistically significant in men, whereas the risk was lower by 25% in women.

CONCLUSIONS: A higher OBS, representing a balance of multiple oxidative stress-related dietary and lifestyle exposures, is associated with a lower risk of MetS. Therefore, adhering to an antioxidant diet and lifestyle may help prevent the occurrence of metabolic disorders.

ABSTRACT

BACKGROUND: Stereotactic body radiation therapy (SBRT) has been widely used for pancreatic cancer. However, there is still a lack of studies comparing the latest SBRT techniques in terms of clinical efficacy and safety.

OBJECTIVES: This study aims to evaluate three latest SBRT delivery platforms: CyberKnife (CK), Tomography Radixact (TOMO), and Halcyon volume rotation intensity modulation therapy (VMAT) for the treatment of pancreatic cancer.

METHODS: Sixteen patients with pancreatic cancer treated with CK were retrospectively analyzed. SBRT plans were designed using Precision and Eclipse software. CK plans were optimized in two forms: fixed collimator (CK-Fixed) and multi-leaf grating collimator (CK-MLC). TOMO plans were designed with 2.5 cm Fixed Jaw, pitch 0.123-0.43 and 4.0 modulation factors in precision system. In Eclipse 15.6 system, photon optimizer (OP) algorithm was used to design the coplanar two-arc Halcyon VMAT. The median radiation dose was 40 Gy (35-45 Gy) in 5 fractions. The effectiveness of clinical treatment was evaluated by comparing the homogeneity index (HI), conformity index (CI), coverage of the planning target volume (PTV) and dose distribution parameters of organs at risk (OAR).

RESULTS: All plans met the limits of clinical target dose and OAR. CK-MLC plans had the lowest maximum dose of 2 cm normal tissue from PTV margin (D_2cm), indicating a low risk of peripheral radiation damage. Additionally, the CK-MLC plans had the lowest dose parameters and provided the best protection for the kidney, spinal cord, small intestine, and duodenum, with a paired t-test p < 0.05, indicating a statistical difference.

CONCLUSION: High conformity and adjustability of CK-MLC allowed for precise complex target localization and conformal dose distribution, benefiting tumor treatment while maximally reducing damage to OAR. This study provides valuable dosimetric evidence for SBRT technique selection for pancreatic cancer.

ABSTRACT

BACKGROUND: Restriction of movement at a joint due to disease or dysfunction can alter the range of motion (ROM) at other joints due to joint interactions. In this paper, we quantify the extent to which joint restrictions impact upper limb joint movements by conducting a disability simulation study that used wearable inertial sensors for three-dimensional (3D) motion capture.

METHODS: We employed the Wearable Inertial Sensors for Exergames (WISE) system for assessing the ROM at the shoulder (flexion-extension, abduction-adduction, and internal-external rotation), elbow (flexion-extension), and forearm (pronation-supination). We recruited 20 healthy individuals to first perform instructed shoulder, elbow, and forearm movements without any external restrictions, and then perform the same movements with restriction braces placed to limit movement at the shoulder, elbow, and forearm, separately, to simulate disability. To quantify the extent to which a restriction at a non-instructed joint affected movement at an instructed joint, we computed average percentage reduction in ROM in the restricted versus unrestricted conditions. Moreover, we performed analysis of variance and post hoc Tukey tests (q statistic) to determine the statistical significance (p < 0.05 denoted using ^*) of the differences in ROM of an instructed joint in the unrestricted versus restricted conditions.

RESULTS: Restricting movement at the shoulder led to a large reduction in the average ROM for elbow flexion-extension (21.93%, q = 9.34^*) and restricting elbow movement significantly reduced the average ROM for shoulder flexion-extension (17.77%, q = 8.05^*), shoulder abduction-adduction (19.80%, q = 7.60^*), and forearm pronation-supination (14.04%, q = 4.96^*). Finally, restricting the forearm significantly reduced the average ROM for shoulder internal-external rotation (16.71%, q = 3.81^*) and elbow flexion-extension (10.01%, q = 4.27^*).

CONCLUSIONS: Joint interactions across non-instructed joints can reduce the ROM of instructed movements. Assessment of ROM in the real-world using 3D motion capture, for example using the WISE system, can aid in understanding movement limitations, informing interventions, and monitoring progress with rehabilitation.

ABSTRACT

BACKGROUND: Respiratory syncytial virus (RSV) is an important cause of acute lower respiratory infections worldwide, including Thailand. This study aimed to assess clinical and economic burdens of RSV infections across different age groups in Thailand.

METHOD: A retrospective cohort study was conducted using data from a tertiary care hospital from 2014 to 2021. Patients who tested at least one positive RSV were included and stratified into five age groups (< 2, 2-5, 5-18, 18-65, and > 65 years). Healthcare resource utilization, direct medical costs, and clinical outcomes were analyzed with descriptive statistics. Generalized linear models with gamma distributions and log link were used to model cost outcomes. Costs were reported in 2021 US dollars (USD), with 1 USD = 31.98 Thai Baht.

RESULTS: A total of 2122 RSV-positive patients were identified, half of which (1097) were hospitalized. The median (interquartile range [IQR]) total hospitalization costs ranged from USD780 (IQR: USD488-USD1185) in those < 2 years to USD2231 (IQR: USD1250-USD4989) in those aged 65+ years. Case fatality rates among hospitalized patients also varied from 2.5% to 28.4% depending on age. Increased age, presence of comorbidities, and need for critical care were associated with higher hospitalization costs.

CONCLUSION: Among RSV-positive patients, younger children experienced the greatest burden, but poorer outcomes were observed in older adults. Higher costs were associated with older age, comorbidities and critical care needs. Understanding RSV economic burdens is crucial for assessing the cost-effectiveness and public health value of vaccination programs that prioritize at-risk groups to mitigate the public health impact.

ABSTRACT

BACKGROUND: Hepatitis virus infection remains a serious public health concern worldwide. Percutaneous, mucosal, or non-intact skin exposure to infectious blood, semen, and other body fluids are the major routes of infection in endemic areas, including Ethiopia, where little is known about the community’s knowledge, attitudes, and practice toward hepatitis infection. Thus, this study aimed to determine the knowledge, attitude, and practices towards hepatitis infection among adults in Gondar town.

METHODS: A community-based cross-sectional study was conducted from July to August 2021 on a total of 390 participants. Proportional sample allocation was used in 3 randomly selected sub-cities. Then, study participants from randomly selected households were recruited by using a systematic random sampling technique. Socio-demographic data and questions regarding KAP were collected via a self-administered and interviewer-administered questionnaire. Statistical analysis was performed using SPSS version 20. Logistic regression analyses were used to identify the associated factors and a p-value < 0.05 was considered statistically significant.

RESULTS: The mean age of the study participants was 30 ± 8.43 years and more than half ½ (53.3%) ranged from 26 to 40 years old. In this study, 335 (85.9%) of study participants had poor knowledge about hepatitis infection. About 344 (88.2%) had a negative attitude toward hepatitis infections, and 344 (88.2%) of the participants had a poor practice to prevent hepatitis infections. Multivariate analysis affirmed that having vaccination for hepatitis infection was significantly associated with a positive attitude (AOR, with 95% CI: 2.135 (1.006-4.532) and good practice levels (AOR, with 95% CI: 22.623 (0.032-0.156).

CONCLUSIONS AND RECOMMENDATIONS: In this study majority of the participants have poor knowledge, attitudes, and practices toward hepatitis infection. Therefore, targeted community-based interventions are necessary. However, this study revealed that having vaccination for hepatitis infection was significantly associated with a positive attitude and good practice levels among the study participants.

ABSTRACT

BACKGROUND: Suicidal ideation may be a warning sign for suicide and previous work has indicated a higher prevalence of suicidal ideation during the COVID-19 pandemic. Job loss and job insecurity are potential risk factors for suicidal ideation, but their importance during the pandemic, and the role of organizational changes for suicidal ideation, is unclear. This study examined the association between various experiences associated with job loss and job insecurity during the pandemic and thoughts of suicide/self-harm in Sweden.

METHODS: The study sample was drawn from the Swedish Longitudinal Occupational Survey of Health (SLOSH). Auxiliary data collections in February 2021 and 2022 assessed exposure to job loss/unemployment, furlough, workplace downsizing, or increased job insecurity versus stable employment and thoughts of suicide or self-harm (PHQ-9) during the pandemic. The analyses were based on 1558 individuals (2 349 observations) participating in either or both waves and who had been working before the pandemic. Logistic regression models with cluster-robust standard errors were fitted, including sociodemographic factors and prior mental health problems to control for potential confounding. Measures of personality based on a brief version of the Big-Five personality inventory were also added.

RESULTS: The results indicated an association between all experiences, except furlough, and thoughts of suicide/self-harm, when adjusting for sex, age, civil status, socioeconomic status and prior mental health (job loss odds ratio (OR) = 3.70, 95% confidence interval (CI) 1.79-7.63, downsizing OR = 2.41, CI 1.24-4.70, job insecurity OR = 2.77, CI 1.15-6.67). The associations for job loss and insecurity were attenuated by adjustment for personality, although it remained statistically significant for downsizing.

CONCLUSIONS: The results suggested a higher risk of suicidal ideation connected with loss of employment and survival of a downsizing, but not a forced reduction in working times/pay during the COVID-19 pandemic. The association for subjective job insecurity was less robust and may be partly explained by personality.

ABSTRACT

BACKGROUND: Pre-hospital incidents involving pediatric and neonatal patients are infrequent, and clinical characteristics and care for these patients differ from the adult population. Lack of knowledge, guidelines, and experience can make pre-hospital pediatric care challenging, and there is limited research on the epidemiology and best practice of care for this population. We examined the pre-hospital pediatric population in the county of Sør-Trøndelag, Norway, to improve our understanding of this population in our region.

METHODS: We conducted a retrospective observational cohort study of emergency incidents involving children under twelve years of age with dispatch of Emergency Medical Services (EMS) in Sør-Trøndelag between 2018 and 2022. Incidents and patient characteristics were extracted from the Emergency Medical Communication Center (EMCC) database. In addition, data on patient characteristics and interventions for more serious incidents seen by the Helicopter Emergency Medical Service (HEMS) were included from the database LABAS. We provided descriptive statistics and estimated population incidences using Poisson regression.

RESULTS: The catchment area of EMCC Sør-Trøndelag has a population of approximately 43,000 children under the age of twelve years. During the five-year study period, there were 7005 emergency calls concerning this patient population, representing 6% of all emergency calls (total no. 108,717). Of these, 3500 (50%) resulted in the dispatch of an ambulance and/or HEMS, yielding an annual incidence of EMS dispatches of 17 per 1000 children. The three most common primary medical problems were respiratory distress, altered consciousness, and trauma. Among the 309 HEMS patients, 131 (42%) received advanced interventions from the HEMS physician. Assisted ventilation was the most frequent intervention.

CONCLUSIONS: Pediatric and neonatal patients make up a small proportion of pre-hospital patient dispatches in Sør-Trøndelag. Consequently, each EMS provider infrequently encounters children in the pre-hospital environment, resulting in less experience with pediatric advanced medical interventions. This study identifies some clinical characteristics and interventions regarding pediatric and neonatal patients that have been pointed out as focus areas for pediatric pre-hospital research.

ABSTRACT

BACKGROUND: Gestational diabetes mellitus (GDM) is a common pregnancy complication characterized by insulin resistance. A link has been suggested between insulin resistance and breast cancer, which is the most common cancer in women. Hence, women with previous GDM may be at increased risk of developing breast cancer, yet, the existing evidence is conflicting. This study explored the association between GDM and incident breast cancer, including age at cancer diagnosis. Additionally, we investigated the potential impact of severity of insulin resistance during pregnancy and of subsequent diabetes development on the breast cancer risk.

METHODS: We conducted a nationwide, register-based cohort study including all women giving birth in Denmark from 1997 to 2018. We defined GDM and breast cancer based on ICD-10 codes. Premenopausal and postmenopausal breast cancer was pragmatically defined as age at outcome < 50 years and ≥ 50 years, respectively. A proxy for severity of insulin resistance during pregnancy was based on insulin treatment; subsequent diabetes was defined as presence of ICD-10 codes and/or antidiabetic medication after pregnancy. The statistical analyses included Cox regression, logistic regression and t-test.

RESULTS: Of 708,121 women, 3.4% had GDM. The median follow-up period was 11.9 years (range 0-21.9). The overall breast cancer risk was comparable in women with and without previous GDM (adjusted hazard ratio 0.96 [95% CI 0.83-1.12]). Premenopausal and postmenopausal breast cancer risk also did not differ; however, women with previous GDM had a breast cancer diagnosis at younger age (42.6 vs. 43.5 years, p-value 0.01). All-cause mortality was similar regardless of GDM history. Severity of insulin resistance during pregnancy and subsequent diabetes did not affect breast cancer risk.

CONCLUSIONS: This large, population-based cohort study showed no higher risk of incident breast cancer in women with previous GDM compared to women without previous GDM after a median of almost 12 years of follow-up. This was evident irrespective of menopausal state. The breast cancer risk was not influenced by the severity of insulin resistance during pregnancy and by subsequent diabetes development. Regardless of GDM history, attention towards prevention, early detection and treatment of breast cancer should be prioritized.
