Chemical Composition and Antibacterial Activity of the Essential Oil of Baccharis latifolia Pers. and B. Prunifolia H. B. &K. (Asteraceae)

The essential oils from leaves of Baccharis latifolia and B. prunifolia collected in January 2006 were analyzed by GC/MS. The yields of oils extracted by hydrodistillation were 0.27 and 0.29% for B. latifolia and B. prunifolia, respectively. Sixteen (B. latifolia) and twenty nine (B. prunifolia) components were identified by comparison of their mass spectra with the Wiley GC-MS Library data and by their retention indices (RI). The identified products may be divided into four different groups: monoterpenes (9.0% B. latifolia; 43.9% B. prunifolia), oxygenated monoterpenes (0.8% B. latifolia; 5.4% B. prunifolia), sesquiterpenes (20.4% B. latifolia; 45.9% B. prunifolia) and oxygenated sesquiterpenes (69.8% B. latifolia; 1.9% B. prunifolia). The oils showed antibacterial activity only against Gram positive bacteria, with MIC values for Staphylococcus aureus (ATCC 25923) of 80 μg/mL (B. latifolia) and Enterococcus faecalis (ATCC 29212) of 90 μg/mL and 260 μg/mL (B latifolia and B. prunifolia, respectively).
Commentary on “Simultaneous Single-Position Oblique Lateral Interbody Fusion Combined With Unilateral Percutaneous Pedicle Screw Fixation for Single-Level Lumbar Tuberculosis: A 3-Year Retrospective Comparative Study”

Spinal tuberculosis (TB) can lead to spinal deformities and neurological deficits. The diagnosis of spinal TB involves a combination of various modalities, such as clinical evaluations, imaging features, acid-fast stain smear, mycobacterial culture, and histologic and/or cytologic assessments. 1 The rationale for surgical intervention lies in preserving neurological function and preventing spinal kyphotic deformity. 2 The choice of surgical strategies, including decompression and instrumentation for stabilization and correction of deformities, is determined on a case-by-case basis. 1 The optimal timing for surgical intervention in patients with spinal TB is still a subject of debate. Performing surgery during the active stage is generally considered more feasible for spinal correction than in the healed stage. 1 Spinal TB in the healed stage may result in angular deformities, with or without associated neurological deficits. 3 Combined approaches may involve anterior corpectomy, posterior shortening and instrumentation, and anterior and posterior grafting. 4,5 The selection of the technique depends on the severity of the angular deformity. This article 6 presents a retrospective comparative study conducted over 3 years, focusing on the treatment of single-level lumbar tuberculosis using a simultaneous single-position oblique lateral interbody fusion (SP-OLIF) combined with unilateral percutaneous pedicle screw fixation. This approach provides a minimally invasive alternative to the traditional posterior-only approach. The study aimed to evaluate the SP-OLIF approach in comparison to the traditional posterior-only method in terms of clinical and radiographic outcomes. The study included 136 patients, with 60 in the SP-OLIF group and 76 in the posterior-only group. Results showed that the SP-OLIF group exhibited significantly lower mean operative time, blood loss, and hospital stay compared to the posterior-only group. The SP-OLIF group also demonstrated a lower complication rate. Clinical efficacy evaluation revealed lower vi-Neurospine
Future directions of lung‐protective ventilation strategies in acute respiratory distress syndrome

Abstract Acute respiratory distress syndrome (ARDS) is characterized by the heterogeneous distribution of lung aeration along a gravitational direction due to increased lung density. Therefore, the lung available for ventilation is usually limited to ventral, nondependent lung regions and has been called the “baby” lung. In ARDS, ventilator‐induced lung injury is known to occur in nondependent “baby” lungs, as ventilation is shifted to ventral, nondependent lung regions, increasing stress and strain. To protect this nondependent “baby” lung, the clinician targets and limits global parameters such as tidal volume and plateau pressure. In addition, positive end‐expiratory pressure (PEEP) is used to prevent dorsal, dependent atelectasis and, if successful, increases the size of the baby lung and lessens its susceptibility to injury from inspiratory stretch. Although many clinical trials have been performed in patients with ARDS over the last two decades, there are few successfully showing benefits on mortality (ie, prone positioning and neuromuscular blocking agents). These disappointing results contrast with other medical disciplines, especially in oncology, where the heterogeneity of diseases is recognized widely and precision medicine has been promoted. Thus, lung‐protective ventilation strategies need to take an innovative approach that accounts for the heterogeneity of injured lungs. This article summarizes ventilator‐induced lung injury and ARDS and discusses how to implement precision medicine in the field of ARDS. Potentially useful methods to individualize PEEP with esophageal balloon manometry, lung recruitability, and electrical impedance tomography were discussed.
Review of Language and Learning in the Digital Age

Review by Paul Rama, University of California Irvine Gee and Hayes’ latest work, Language and Learning in the Digital Age, is an informative read dealing with the potential, perils, and implications of digital media. Parallels and comparisons are drawn between oral language, literacy (defined as reading and writing), and digital media, and how these latter two have altered the way we communicate and interact. As leading authorities on games and learning, Gee and Hayes illustrate their arguments with examples from video games, including Second Life and World of Warcraft. These, along with non-game examples such as a cat listserv, “birding” (p. 72), and amateur science, contrast school learning with that found in “passionate affinity spaces” (p. 69), which are argued to be ideal spaces for personally meaningful, situated learning. The authors challenge institutionally valued literacy skills, which have been reinforced in our current school systems. The book’s title describes the content of this work, which succeeds in illustrating how language, which is essential to learning, is once again being shaped, this time by digital media.
Dissecting sexual minority subgroup differences in the association between depression, anxiety, and cognitive difficulties

Introduction A growing body of research has demonstrated extensive mental health disparities affecting sexual minority populations, yet little research has assessed how these disparities may affect cognitive functioning among subgroups of sexual minorities. Methods Data come from the 2021 National Health Information Survey (NHIS). Survey-weighted linear regression analyses were used to assess self-reported measures of cognition, stratified by subgroups sexual identity. In particular, we focused on the association between symptoms of depression or anxiety and each of the measures of cognition, adjusting for demographic covariates. Results Among 31,994 NHIS participants in the 2021 survey, 5,658 (17.7%) reported at least some difficulty in remembering or concentrating. Basic demographic differences existed when assessing any cognitive difficulty, particularly for bisexual participants (aOR = 2.73; 95% CI: 2.07, 3.60) and participants identifying as a different identity (aOR = 4.22; 95% CI: 2.72, 6.56). Depression was significantly associated with cognitive difficulty with the largest relationship observed among gay/lesbian participants (aOR = 1.39; 95% CI: 1.29, 1.49). The association between anxiety and cognitive difficulty was smallest among bisexuals (aOR = 1.13; 95% CI: 1.08, 1.18) and relatively consistent across other subgroups: heterosexuals (aOR = 1.23; 95% CI: 1.22, 1.24), gay/lesbians (aOR = 1.27; 95% CI: 1.19, 1.36), and those with a different identity (aOR = 1.22; 95% CI: 1.10, 1.35). Conclusion There is a clear set of health disparities between sexual minority subgroups and heterosexuals across all cognitive difficulties. Future research should focus on developing a better understanding of differences in cognition based on sexual minority status while also working to ascertain how disparities vary among sexual minorities.
Mesenchymal Stem Cells Combined With Electroacupuncture Treatment Regulate the Subpopulation of Macrophages and Astrocytes to Facilitate Axonal Regeneration in Transected Spinal Cord

Objective Herein, we investigated whether mesenchymal stem cells (MSCs) transplantation combined with electroacupuncture (EA) treatment could decrease the proportion of proinflammatory microglia/macrophages and neurotoxic A1 reactive astrocytes and inhibit glial scar formation to enhance axonal regeneration after spinal cord injury (SCI). Methods Adult rats were divided into 5 groups after complete transection of the spinal cord at the T10 level: a control group, a nonacupoint EA (NA-EA) group, an EA group, an MSC group, and an MSCs+EA group. Immunofluorescence labeling, quantitative real-time polymerase chain reaction, enzyme-linked immunosorbent assay, and Western blots were performed. Results The results showed that MSCs+EA treatment reduced the proportion of proinflammatory M1 subtype microglia/macrophages, but increased the differentiation of anti-inflammatory M2 phenotype cells, thereby suppressing the mRNA and protein expression of proinflammatory cytokines (tumor necrosis factor-α and IL-1β) and increasing the expression of an anti-inflammatory cytokine (interleukin [IL]-10) on days 7 and 14 after SCI. The changes in expression correlated with the attenuated neurotoxic A1 reactive astrocytes and glial scar, which in turn facilitated the axonal regeneration of the injured spinal cord. In vitro, the proinflammatory cytokines increased the level of proliferation of astrocytes and increased the expression levels of C3, glial fibrillary acidic protein, and chondroitin sulfate proteoglycan. These effects were blocked by administering inhibitors of ErbB1 and signal transducer and activator of transcription 3 (STAT3) (AG1478 and AG490) and IL-10. Conclusion These findings showed that MSCs+EA treatment synergistically regulated the microglia/macrophage subpopulation to reduce inflammation, the formation of neurotoxic A1 astrocytes, and glial scars. This was achieved by downregulating the ErbB1-STAT3 signal pathway, thereby providing a favorable microenvironment conducive to axonal regeneration after SCI.
CS1, a controlled‐release formulation of valproic acid, for the treatment of patients with pulmonary arterial hypertension: Rationale and design of a Phase 2 clinical trial

Abstract Although rare, pulmonary arterial hypertension (PAH) is associated with substantial morbidity and a median survival of approximately 7 years, even with treatment. Current medical therapies have a primarily vasodilatory effect and do not modify the underlying pathology of the disease. CS1 is a novel oral, controlled‐release formulation of valproic acid, which exhibits a multi‐targeted mode of action (pulmonary pressure reduction, reversal of vascular remodeling, anti‐inflammatory, anti‐fibrotic, and anti‐thrombotic) and therefore potential for disease modification and right ventricular modeling in patients with PAH. A Phase 1 study conducted in healthy volunteers indicated favorable safety and tolerability, with no increased risk of bleeding and significant reduction of plasminogen activator inhibitor 1. In an ongoing randomized Phase 2 clinical trial, three doses of open‐label CS1 administered for 12 weeks is evaluating the use of multiple outcome measures. The primary endpoint is safety and tolerability, as measured by the occurrence of adverse events. Secondary outcome measures include the use of the CardioMEMS™ HF System, which provides a noninvasive method of monitoring pulmonary artery pressure, as well as cardiac magnetic resonance imaging and echocardiography. Other outcomes include changes in risk stratification (using the REVEAL 2.0 and REVEAL Lite 2 tools), patient reported outcomes, functional capacity, 6‐min walk distance, actigraphy, and biomarkers. The pharmacokinetic profile of CS1 will also be evaluated. Overall, the novel design and unique, extensive clinical phenotyping of participants in this trial will provide ample evidence to inform the design of any future Phase 3 studies with CS1.
Therapeutic Prediction of Osteoporotic Vertebral Compression Fracture Using the AO Spine-DGOU Osteoporotic Fracture Classification and Classification-Based Score: A Single-Center Retrospective Observational Study

Objective The treatment of osteoporotic vertebral compression fractures (OVCFs) is based on their severity; however, an efficient prediction tool is lacking. We aimed to evaluate the validity of the osteoporotic fracture classification (OF classification) and scoring system (OF score) in predicting the treatment strategy for patients with OVCF, defined according to the Japanese criteria. Methods We retrospectively investigated 487 consecutive patients diagnosed with vertebral body fractures between January 2018 and December 2022. Only patients with their fresh vertebral fracture episode during the study period were included. Patients were classified into 3 groups: conservative treatment, balloon kyphoplasty (BKP), and open surgery. OF classification and OF scores were assessed for each patient. Results A total of 237 patients with OVCF were included. There were 127, 81, and 29 patients in the conservative, BKP, and open surgery groups, respectively. The OF score was significantly higher in the BKP and open surgery groups than in the conservative group (p < 0.001). Multivariate logistic regression analysis showed that antiosteoporotic drug use, OF classification, progressive deformity, neurological symptoms and mobilization were independent risk factors for operative treatment (all p < 0.001). Receiver operating characteristic analysis showed that the cutoff OF score for operative indication was 5.5, with a sensitivity of 91.9%, specificity of 56.5%, and area under the curve of 0.820 (95% confidence interval, 0.769–0.871). Conclusion The OF score identified patients who required operative treatment with a high degree of accuracy. This is especially important for ruling out patients who definitely require operative treatment.
SRY gene isolation from teeth for forensic gender identification—An observational study

Personal identification in forensics is possible with gender determination using DNA (deoxyribonucleic acid) analysis. DNA isolation from teeth samples subjected to extreme temperatures has been shown to predict the gender of the deceased. However, the literature lacks studies on DNA extracted from tooth samples exposed to freezing temperatures. This study aimed to isolate the SRY gene from the extirpated pulp of teeth that were subjected to varying temperatures for gender identification. Thirty teeth with vital pulps, divided into 3 groups were included in the study. Each group consisted of 5 male and 5 female tooth samples. The groups were exposed to diverse environmental factors for three weeks. Group 1: room temperature (R group); Group 2: high temperature (H group) and Group 3: freezing temperature (F group). Later, DNA was isolated from the pulp tissue, and the SRY gene was amplified using PCR (Polymerase Chain Reaction). The Sensitivity and Specificity of the results were analyzed. SRY gene detected in the study samples identified accurate gender with a 46.70% Sensitivity and 93.30% Specificity. Significant difference was found in the correlation between gene expression and gender among the three groups (p = 1.000). The study validates that dental pulp tissue can be a reliable source for DNA extraction. And SRY gene amplification from teeth exposed to diverse environmental conditions. Further investigations are required to validate its application in forensics.
Estimating probability of extreme rainfall over Japan using Extended Regional Frequency Analysis

: A method of frequency analysis, Extended Regional Frequency Analysis (ERFA), is proposed for reliable estimates of extreme daily rainfall probabilities for a long return period from relatively short daily rainfall records. The method uses combined data in a wide meteorologically homogeneous region (e.g., all Japan) to ensure a large number (order of 10,000) of data to minimize the effects of statistical sampling error in the frequency analysis. We applied the ERFA to daily rainfall data observed over Japan and to a high reso-lution atmospheric model simulation data over the meteorologically homogeneous land region of Japan. We found very good agreement between the empirical probability distribution and theoretical distribution estimated by ERFA, sug-gesting that the method is promising. However, we have noted some problems regarding ERFA: selection of the distribution, selection of the region, and model bias. These problems, along with possible solutions, are discussed.
The first reported case of intravascular ultrasound-guided reverse overlapping stenting of a long calcified lesion using ultra-low contrast and metallic roadmaps: case report

Abstract Background Percutaneous coronary intervention (PCI) of a long calcified coronary lesion in patients with chronic kidney disease (CKD) is challenging and can lead to stent under-expansion and contrast-induced acute kidney injury (CI-AKI). We described the first case of intravascular ultrasound (IVUS)-guided reverse overlapping stenting of long calcified left anterior descending (LAD) coronary lesion using ultra-low contrast and the metallic roadmaps to prevent CI-AKI after PCI. Case summary A 77-year-old man with a history of hypertension, type 2 diabetes, and CKD was admitted with angina class 4 and ruled in for non-ST-elevation myocardial infarction. His ejection fraction was 40%. He was referred for cardiac catheterization and PCI. Coronary angiography showed a long calcified stenosis of the LAD. IVUS catheter was advanced at least 10 mm distal to the lesion or stent edge. IVUS images were obtained with automated pullback (1 mm/s) using a commercially available IVUS system with a 60-MHz mechanical transducer (Boston Scientific, Natick, Massachusetts). IVUS showed calcified plaque fractures after balloon angioplasty and intracoronary lithotripsy. The first stent was deployed proximally using the guidewire in the diagonal branch as a metallic roadmap, and the second stent was deployed distally overlapping at the distal edge of the first stent as a roadmap with no contrast injection. Percutaneous coronary intervention was completed successfully using only 12 mL contrast. Glomerular filtration rate remained stable after PCI. Glomerular filtration rate and ejection fraction improved at 12-month follow-up. Discussion We described the first case of the reverse overlapping stenting technique guided by IVUS with no contrast in a patient with CKD and a long calcified LAD lesion. Conventionally, in long lesions, the first stent is deployed distally and the second stent proximally, which requires contrast injection for stent deployment. We demonstrated that the above technique resulted in preventing CI-AKI and improving creatinine as well as ejection fraction at follow-up.
Up-regulation of matrix metalloproteinases in a mouse model of chemically induced colitis-associated cancer: the role of microRNAs

Emerging evidence has implicated microRNAs in regulating the production of multiple inflammatory mediators including cytokines and chemokines. We previously elucidated the dynamic activation of key signals that link colitis to colorectal cancer. In this study, we observed a sharp increase in the levels of matrix metalloproteinases (Mmps) that provided a basis for the inflammation-cancer link, and we questioned whether this was a consequence of the dysregulation of Mmp-specific microRNAs, at least partly. We assayed a panel of murine microRNAs that were predicted to target Mmps and found they were downregulated in the inflammation-cancer link. Furthermore, we demonstrated that three murine microRNAs, namely miR-128, -134, and -330, can target the three Mmps Mmp3, Mmp10, and Mmp13, respectively. We also found that the level of the microRNA-processing enzyme Dicer1 was decreased in the inflammation-cancer link. These microRNAs functioned as tumor suppressors in colon cancer cells, attenuating the proliferation, migration, and invasion potential of murine colon cancer cells as well as angiogenesis and the growth of tumors derived from these cells. Our results suggest that microRNAs modulate the production of key inflammatory mediators and that microRNA dysfunction may contribute to the non-resolving inflammation associated with cancer.
Turkish Real Life Atrial Fibrillation in Clinical Practice: TRAFFIC Study

Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults’ Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes. Methods: The TRAFFIC study is a national, prospective, multicenter, observational registry. The study aims to collect data from at least 1900 patients diagnosed with atrial fibrillation, with the participation of 40 centers from Türkiye. The following data will be collected from patients: baseline demographic characteristics, medical history, vital signs, symptoms of AF, ECG and echocardiographic findings, CHADS2-VASC2 and HAS-BLED (1-year risk of major bleeding) risk scores, interventional treatments, antithrombotic and antiarrhythmic medications, or other medications used by the patients. For patients who use warfarin, international normalized ratio levels will be monitored. Follow-up data will be collected at 6, 12, 18, and 24 months. Primary endpoints are defined as systemic embolism or major safety endpoints (major bleeding, clinically relevant nonmajor bleeding, and minor bleeding as defined by the International Society on Thrombosis and Hemostasis). The main secondary endpoints include major adverse cardiovascular events (systemic embolism, myocardial infarction, and cardiovascular death), all-cause mortality, and hospitalizations due to all causes or specific reasons. Results: The results of the 12-month follow-up of the study are planned to be shared by the end of 2023. Conclusion: The TRAFFIC study will reveal the prevalence and incidence, demographic characteristics, and risk profiles of AF patients in Türkiye. Additionally, it will provide insights into how current treatments are reflected in this population. Furthermore, risk prediction modeling and risk scoring can be conducted for patients with AF.
