Pharmacological interventions for intraplaque neovascularization in atherosclerosis.

Advanced atherosclerosis is linked to plaque instability, which can result in rupture and the onset of a heart attack. Evidence gathered from human atheroma plaques indicates that intraplaque neovascularization poses a risk to plaque stability and may lead to plaque hemorrhage. Hence, targeting the neovascularization within the atheroma plaque has the potential to mitigate the plaque's vulnerability. While neovascularization has been extensively explored in the context of cancer, research on pharmacological inhibition of this phenomenon in atherosclerosis remains limited. This systematic review aimed to comprehensively assess current and emerging pharmacological interventions for inhibiting intraplaque neovascularization in preclinical settings. Electronic databases (Web of Science, PubMed, Scopus, and Ovid) were searched from January 2013 until February 1, 2024. Preclinical studies reporting the effect of any pharmacological interventions targeting intraplaque neovascularization were included. A total of 10 articles involving in vivo animal studies were eligible for inclusion, with five of them incorporating in vitro experiments to complement their in vivo findings. The pharmacological interventions studied were axitinib, ghrelin, K5, rosuvastatin, atorvastatin, 3PO, everolimus, melatonin, Si-Miao-Yong-A, and protocatechuic aldehyde. All the interventions showed a positive impact in inhibiting intraplaque neovascularization in various atherosclerotic animal models through various signaling pathways. This review provides valuable insights into pharmacological approaches to attenuate intraplaque neovascularization that could serve as a promising therapeutic avenue to enhance plaque stability.

Breakthrough-induced loop formation in evolving transport networks.

Transport networks, such as vasculature or river networks, provide key functions in organisms and the environment. They usually contain loops whose significance for the stability and robustness of the network is well documented. However, the dynamics of their formation is usually not considered. Such structures often grow in response to the gradient of an external field. During evolution, extending branches compete for the available flux of the field, which leads to effective repulsion between them and screening of the shorter ones. Yet, in remarkably diverse processes, from unstable fluid flows to the canal system of jellyfish, loops suddenly form near the breakthrough when the longest branch reaches the boundary of the system. We provide a physical explanation for this universal behavior. Using a 1D model, we explain that the appearance of effective attractive forces results from the field drop inside the leading finger as it approaches the outlet. Furthermore, we numerically study the interactions between two fingers, including screening in the system and its disappearance near the breakthrough. Finally, we perform simulations of the temporal evolution of the fingers to show how revival and attraction to the longest finger leads to dynamic loop formation. We compare the simulations to the experiments and find that the dynamics of the shorter finger are well reproduced. Our results demonstrate that reconnection is a prevalent phenomenon in systems driven by diffusive fluxes, occurring both when the ratio of the mobility inside the growing structure to the mobility outside is low and near the breakthrough.

A simple and effective machine learning model for predicting the stability of intracranial aneurysms using CT angiography.

Background: It is vital to accurately and promptly distinguish unstable from stable intracranial aneurysms (IAs) to facilitate treatment optimization and avoid unnecessary treatment. The aim of this study is to develop a simple and effective predictive model for the clinical evaluation of the stability of IAs. Methods: In total, 1,053 patients with 1,239 IAs were randomly divided the dataset into training (70%) and internal validation (30%) datasets. One hundred and ninety seven patients with 229 IAs from another hospital were evaluated as an external validation dataset. The prediction models were developed using machine learning based on clinical information, manual parameters, and radiomic features. In addition, a simple model for predicting the stability of IAs was developed, and a nomogram was drawn for clinical use. Results: Fourteen machine learning models exhibited excellent classification performance. Logistic regression Model E (clinical information, manual parameters, and radiomic shape features) had the highest AUC of 0.963 (95% CI 0.943-0.980). Compared to manual parameters, radiomic features did not significantly improve the identification of unstable IAs. In the external validation dataset, the simplified model demonstrated excellent performance (AUC = 0.950) using only five manual parameters. Conclusion: Machine learning models have excellent potential in the classification of unstable IAs. The manual parameters from CTA images are sufficient for developing a simple and effective model for identifying unstable IAs.

The truly intermediate subgroup within the SINS 'potentially unstable' category: The Matryoshka doll phenomenon.

OBJECTIVE: A significant dilemma exists for the surgical plan of spinal metastases with a Spinal instability neoplastic score (SINS) of 7-12. Our aim is to trim down this range of 'potential instability' and find a virtual cut-off value for instrumentation. METHODS: We performed a retrospective study on 60 patients who underwent surgical intervention for vertebral metastasis. They were segregated into 'instrumented' and 'non-instrumented' groups. The primary endpoint of the study was to see whether surgical stabilization was done. RESULT: Although univariate analysis showed the overall SINS score, involvement of posterior elements, and mechanical pain to be the factors that significantly affected our decision-making in favour of stabilization, only the SINS score was found to be statistically significant on multivariate analysis. On plotting the proportion of patients undergoing stabilization at each SINS score we found the curves to crossover between SINS 8 and 9, ran almost parallel to each other at values 9 and 10 and then seemed to diverge from each other significantly at values above 10. Taking SINS 9 as the cut-off value above which instrumentation is advised, the ROC had a sensitivity of 67.57% (95% CI 50.21% to 81.99%) and specificity of 73.91% (95% CI 51.59% to 89.77%). The area under the curve was 0.79 (0.67-0.91). CONCLUSION: SINS 9-10 seems to be the actual ambiguous subset in the wider subgroup of the 'potentially unstable' category SINS 7-12, like a 'Matryoshka doll'. A SINS value of 9 can be seen as a cut-off value for instrumentation.

Circulating miRNA-21 as a diagnostic biomarker for acute coronary syndrome: a systematic review and meta-analysis of diagnostic test accuracy study.

Background: Both early detection and treatment for acute coronary syndrome (ACS) have positively affected prognosis. A microRNA, miRNA-21 (miR-21), may have additional diagnostic potential for ACS among the others. This systematic review and meta-analysis aimed to evaluate the potential role of miR-21 in identifying ACS. Methods: PubMed, EMBASE and CENTRAL databases were searched up to March 17, 2024, for case-control and cohort studies assessing the diagnostic value of circulating miR-21 in patients with ACS. The search was limited to studies published in either English or Chinese. The primary outcome was the discriminative ability to circulate miR-21 for ACS, represented by the area under the standard receiver operating characteristic curve (AUC) analysis. Meta-analyses combined the AUCs using a random-effects model. Heterogeneity among the studies was detected by the I2 and Q statistics. The quality of the studies included was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2. Publication bias analysis was assessed constructing by the Egger's test (PROSPERO: CRD42020209424). Results: Eleven case-control studies containing a total of 2,413 subjects with 1,236 ACS cases and 1,177 controls were included. The mean age of participants in these studies ranges between 51.0 and 69.0 years. The meta-analysis showed an overall pooled AUC of 0.779 [95% confidence interval (CI): 0.715-0.843], with high heterogeneity noted between the studies (Q statistic =190.64, I2=94.23%, P<0.001). In subgroup analyses according to the subtypes of ACS, a pooled AUC of 0.767 (95% CI: 0.648-0.887) was derived from the studies focused on acute myocardial infarction cases only. The pooled AUC for unstable angina was 0.770 (95% CI: 0.718-0.822). In subgroup analyses according to the types of control groups, pooled AUC for ACS versus healthy controls was 0.779 (95% CI: 0.715-0.843), whereas the pooled AUC for ACS versus unhealthy controls was 0.740 (95% CI: 0.645-0.836). The quality assessment showed that the studies' overall quality was moderate. No evidence of publication bias was noted (P=0.49). Conclusions: Circulating miR-21 shows abilities to differentiate between ACS and non-ACS, suggesting its potential as a novel diagnostic biomarker for ACS. However, the evidence is weakened by high heterogeneity observed among the studies. Further research is essential before it can be applied in clinical practice.

Evaluating Cardiovascular Risks: The Platelet Lymphocyte Ratio and the Neutrophil Lymphocyte Ratio As High-Risk Heart Score Predictors in Non-ST Elevation Myocardial Infarction (NSTEMI) and Unstable Angina Patients.

Introduction Acute coronary syndromes (ACS), encompassing non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA), present significant challenges in risk assessment and management, particularly in resource-constrained environments like India. The burden of cardiovascular diseases in such regions necessitates cost-effective and readily accessible tools for risk stratification. Previous research has emphasized the role of inflammatory markers in coronary artery disease (CAD), prompting investigations into simple and affordable biomarkers for risk assessment. Platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) have emerged as potential biomarkers for thrombotic activity in cardiac illnesses, offering simplicity, accessibility, and cost-effectiveness in risk assessment making them particularly valuable in resource-poor settings like India, where advanced diagnostic tools may be limited. Objective This study aims to evaluate the effectiveness of PLR and NLR as predictors of high-risk HEART (history, ECG, age, risk factors, and troponin) scores in patients with NSTEMI and UA. Methods A prospective cross-sectional study was conducted at the Saveetha Medical College and Hospitals in Chennai, India, from March 2021 to September 2022. The study included 288 adults diagnosed with NSTEMI or UA, aged 18 years and above. The inclusion criteria comprised patients with confirmed diagnoses of NSTEMI or UA based on clinical symptoms, electrocardiographic findings, and cardiac biomarker elevation. The exclusion criteria encompassed patients with active infections, acute traumatic injuries, end-stage renal disease, malignant neoplasms, and ST-elevation myocardial infarction (STEMI). In addition to the HEART score, PLR, and NLR were computed to assess the prognosis of patients admitted to the Saveetha Medical College and Hospitals. Results The statistical analysis revealed significant correlations between PLR, NLR, and HEART score risk categories. The Pearson's correlation coefficient indicated strong associations between PLR/NLR values and HEART score risk groups, suggesting their potential as predictive markers for adverse clinical outcomes. Additionally, analysis of variance (ANOVA) demonstrated significant differences in PLR/NLR values across different HEART score risk categories, further highlighting their relevance in risk stratification. The effect sizes for these correlations were moderate to large, indicating clinically meaningful associations between PLR/NLR and cardiovascular risk. Conclusion In cases of NSTEMI and UA, PLR and NLR show potential as simple and inexpensive indicators of high-risk patients. By leveraging these inexpensive biomarkers, healthcare providers can enhance risk assessment and prognostication in patients presenting with ACS, facilitating timely interventions and tailored management strategies.

Role of S100ß in Patients with Unstable Angina Pectoris: Insights from Quantitative Flow Ratio.

BACKGROUND AND OBJECTIVE: Disturbed autonomic nervous system (ANS) may promote inflammatory, immune, and oxidative stress responses, which may increase the risk of acute coronary events. S100ß has been proposed as a biomarker of neuronal injury that would provide an insightful understanding of the crosstalk between the ANS, immune-inflammatory cells, and plaques that drive atherosclerosis. This study investigates the correlation between S100ß, and functional coronary stenosis as determined by quantitative flow ratio (QFR). METHODS: Patients with unstable angina pectoris (UAP) scheduled for coronary angiography and QFR were retrospectively enrolled. Serum S100ß levels were determined by enzyme-linked immunosorbent assay. The Gensini score was used to estimate the extent of atherosclerotic lesions and the cumulative sum of three-vessel QFR (3V-QFR) was calculated to estimate the total atherosclerotic burden. RESULTS: Two hundred thirty-three patients were included in this study. Receiver operator characteristic (ROC) curve indicated that S100ß>33.28 pg/mL predicted functional ischemia in patients with UAP. Multivariate logistic analyses showed that a higher level of S100ß was independently correlated with a functional ischemia-driven target vessel (QFR ≤0.8). This was also closely correlated with the severity of coronary lesions, as measured by the Gensini score (OR = 5.058, 95% CI: 2.912-8.793, p <0.001). According to 3V-QFR, S100ß is inversely associated with total atherosclerosis burden (B = -0.002, p <0.001). CONCLUSIONS: S100ß was elevated in the functional ischemia stages of UAP. It was independently associated with coronary lesion severity as assessed by Gensini score and total atherosclerosis burden as estimated by 3V-QFR in patients with UAP.

Comparative clinical outcomes and radiological images of clavicle hook plate versus Scorpion Plate® for unstable distal clavicle fractures.

BACKGROUND: Although various surgical methods are available for unstable distal clavicle fractures, consensus remains lacking on the optimal technique. Therefore, the present retrospective study aimed to compare the clavicle hook plate and Scorpion Plate® in terms of clinical outcomes and radiological findings for unstable distal clavicle fractures. METHODS: Fifty-seven patients with unstable distal clavicle fractures who underwent treatment using a clavicle hook plate (Group H; 28 patients) or Scorpion Plate® (Group S; 29 patients) were included in the present study. No patients received additional augmentation and all were followed-up for >1 year (mean follow-up, 28 months). Clinical outcomes were operation time, bleeding volume, complications, range of motion (ROM) at 6 months after surgery and final follow-up, and clinical scores (Constant-Murley score and University of California, Los Angeles (UCLA) shoulder score). Radiological outcomes assessed were coracoclavicular distance (CCD), difference in CCD between affected and non-affected sides (ΔCCD), and acromioclavicular subluxation ratio (%ACS) from plain X-rays. The χ2 test and Mann-Whitney U test were used to compare each outcome. RESULTS: Complications were seen in 3 shoulders (10.7%) in Group H. ROM was significantly worse in Group H at 6 months postoperatively, but no significant differences between groups were evident at final follow-up. Moreover, no significant differences in clinical outcomes were seen between groups. In terms of radiological results, Group H showed greater improvement in CCD and ΔCCD than Group S. Further, %ACS was significantly worse in Group S. CONCLUSIONS: The clavicle hook plate allows reconstruction of a more anatomical position than the Scorpion Plate®, but carries a greater risk of complications. Conversely, the Scorpion Plate® has a low risk of complications, but acromioclavicular subluxation remains. However, no significant differences in ROM or clinical outcomes were apparent at final follow-up.

A Rare Encounter: Unstable Vasospastic Angina Induced by Thyrotoxicosis.

Coronary artery vasospasm plays a crucial role in the prevalence of unstable angina. Despite common misdiagnosis, there is limited evidence on this topic. Here, we present a rare case of unstable vasospastic angina in a female with severe thyrotoxicosis. Case Report: A 62-year-old female patient was admitted to the cardiac intensive care unit due to crushing chest pain at rest. The patient exhibited ischemic changes on the ECG with a normal troponin I level. Recurrent chest pain prompted urgent coronary angiography, revealing generalized vasospasm of all coronary artery branches including the left main coronary artery. Intracoronary nitroglycerin injection partially alleviated the vasospasm; however, there was a persistent stenosis in the left main artery. Subsequent intravascular ultrasound demonstrated an anatomically normal left main artery. Post-procedure, laboratory tests revealed undetectable levels of thyroid-stimulating hormone and thyroid hormones above the detectable level. The patient was initiated on methimazole and discharged symptom-free, expecting a good prognosis under conservative management. Conclusions: Clinically significant coronary vasospasm triggered by thyrotoxicosis remains a rarity in clinical practice, often posing diagnostic challenges. This case emphasizes the significance of intracoronary nitroglycerin and intravascular ultrasound in discerning the etiology of coronary lesions seen on angiography. We advocate for these techniques to optimize invasive coronary artery diagnostics, enabling the selection of the appropriate treatment strategies and improving long-term prognosis.

Latin-American guidelines of recommendations at discharge from an acute coronary syndrome.

The diagnostic criteria, treatments at the time of admission, and drugs used in patients with acute coronary syndrome are well defined in countless guidelines. However, there is uncertainty about the measures to recommend during patient discharge planning. This document brings together the most recent evidence and the standardized and optimal treatment for patients at the time of discharge from hospitalization for an acute coronary syndrome, for comprehensive and safe care in the patient's transition between care from the acute event to the outpatient care, with the aim of optimizing the recovery of viable myocardium, guaranteeing the most appropriate secondary prevention, reducing the risk of a new coronary event and mortality, as well as the adequate reintegration of patients into daily life.

Los criterios diagnósticos, los tratamientos en el momento de la admisión y los fármacos utilizados en pacientes con síndrome coronario agudo están bien definidos en innumerables guías. Sin embargo, existe incertidumbre acerca de las medidas para recomendar durante la planificación del egreso de los pacientes. Este documento reúne las evidencias más recientes y el tratamiento estandarizado y óptimo para los pacientes al momento del egreso de una hospitalización por un síndrome coronario agudo, para un cuidado integral y seguro en la transición del paciente entre la atención del evento agudo y el cuidado ambulatorio, con el objetivo de optimizar la recuperación de miocardio viable, garantizar la prevención secundaria más adecuada, reducir el riesgo de un nuevo evento coronario y la mortalidad, así como la adecuada reinserción de los pacientes en la vida cotidiana.

Inducing unstable walking conditions through visual and auditory stimuli.

[Purpose] Falls can significantly affect elderly individuals. However, most current methods used to detect and analyze high-risk conditions make use of simulated falling movements for data collection, which may not accurately represent actual falls. The present study aimed to induce natural falls using visual and auditory stimuli to create unstable walking conditions. [Participants and Methods] Two experiments were performed. The first experiment focused on inducing unstable walking using visual stimuli; whereas, the second experiment combined visual and auditory stimuli. To investigate the effects of stimuli on the induction of unstable walking, our results were compared with those of normal walking conditions. In addition, the two experimental conditions were compared to identify the most effective stimuli. [Results] Both experiments revealed a decrease in step length, an increase in step time and width, and an increase in the coefficient of variation of measurements, indicating an induced walking pattern with a higher risk of falls. Furthermore, combining visual and auditory stimuli caused deterioration of inter-limb coordination, as observed through an increased phase coordination index, thus resulting in further instability during walking. [Conclusion] Visual and auditory stimuli induced unstable walking. In particular, the combination of visual and auditory stimuli with a 0.8-s rhythm increased instability.

A Comparative Study of Functional Outcomes in Unstable Pelvic Ring Fractures Treated With Internal Fixator (INFIX) With and Without Sacroiliac Joint Screw Fixation.

Introduction Despite constituting only 3-8% of orthopedic trauma cases, pelvic injuries are associated with high mortality rates, emphasizing the critical need for stable fixation rather than merely anatomical alignment. The use of an anterior, subcutaneous, internal pelvic fixator (INFIX), a novel technique, has shown promise in treating these injuries. Posterior pelvic ring injuries are challenging because they require a significant level of surgical training and technical expertise, and each treatment method has disadvantages. The aim of this study is to compare the clinical and biomechanical outcomes of INFIX with and without sacroiliac screw fixation for unstable pelvic fractures. Methods and methodology Retrospectively, we selected 20 patients with unstable pelvic ring injuries who had come to a high-volume tertiary care hospital and medical college in the state of Maharashtra, India. All the patients were operated on with INFIX; 10 with a sacroiliac joint screw and 10 without a sacroiliac joint screw. We followed up with the patients for six months and evaluated them according to the Majeed score. Results Functional outcomes differed little between INFIX patients operated on with and without a sacroiliac joint screw. However, morbidity, hospital stay, the need for ICU, radiation exposure, and technical ease of surgery were improved in INFIX patients without the sacroiliac screw procedure. We noted an average Majeed score of 78 in the INFIX-alone group and 77.2 in the group that received INFIX with a sacroiliac joint screw. Six months after the surgery, the patients showed signs of a stable bony union, had achieved a full range of motion, and reported no problems in their day-to-day work. Conclusion Although this was a short-term study, we conclude that INFIX without a sacroiliac joint screw showed a comparable functional outcome compared to INFIX with a sacroiliac joint screw. Patients with INFIX alone showed better results; they had reduced surgical time, reduced radiation exposure, and less evidence of neurological harm to the L5-S1 nerve root. The procedure was less complicated and easier for surgeons to learn. Its simplicity and speed were especially beneficial for obese patients.

Splitting the subscapularis at the upper two-third and lower one-third junction or in the middle during the Latarjet-Walch procedure does not affect the external rotation range of motion.

BACKGROUND: Our purpose was to investigate (1) the difference in external rotation range of motion (ROM) limitation between the two recommended subscapularis-splitting techniques (mid-split versus upper 2/3rd -lower 1/3rd split) and (2) the differences in elevation ROM, internal rotation ROM, the functional outcomes and the internal rotation strength between the two techniques in the Latarjet-Walch procedure. MATERIAL AND METHODS: We conducted a prospective cohort study of patients with recurrent shoulder instability treated by the Latarjet-Walch procedure between January 2021 and January 2022. After a priori calculation of sample size, 32 patients were divided into two groups according to the type of intraoperative subscapularis split [upper 2/3rd -lower 1/3rd level split (LS group, n=19) versus mid-level split (MS group, n=13)] performed in the Latarjet-Walch procedure. RESULTS: The final ER1 (external rotation with the arm adducted) deficit (as compared to opposite normal shoulder) was not significantly different between the LS (9° ± 8°) and the MS (10° ± 8°, p=0.8) groups. The final ER2 (external rotation with the elbow abducted @ 90°) deficit was not significantly different between that of the LS (14° ± 12°) and the MS groups (12° ± 9°, p=0.5). Only in the MS group were the final ER1 deficit (p=0.03) and the final ER2 deficits (p=0.05) significantly better (smaller) than the corresponding baseline values. The Rowe scores (p=0.2) and the shoulder subjective value (p=0.7) were not significantly different between the two groups. There were no postoperative subluxations in either group. However, 3 patients tested positive in apprehension testing in the LS group compared to none in the MS group, the difference being statistically insignificant. The internal rotation strength was 95% of the normal, unaffected shoulder in the LS group and 93% of the normal in the MS group (p=0.6). Computed tomography (CT) scan evaluation showed that the transverse diameter index of subscapularis (upper subscapularis diameter / lower subscapularis diameter) was not different in the MS (0.9 ± 0.1) and the LS (0.9 ± 0.1, p=0.3) groups. CONCLUSION: We found no difference in final external rotation limitation between the upper 2/3rd - lower 1/3rd versus mid-level subscapularis split techniques. The functional outcomes, the internal rotation strength, subscapularis transverse diameter index, and fatty infiltration in the CT scan were similar in both groups.

Atraumatic splenic rupture after administering aspirin, clopidogrel, and heparin to a patient with unstable angina: A case report.

It is a rare clinical phenomenon when a normal spleen ruptures spontaneously without any prior trauma. We present a 49-year-old male patient who was discovered to have a splenic rupture after he was referred to our facility as a case of unstable angina for cardiac catheterization based on nonspecific electrocardiogram (ECG) abnormalities and symptoms of chest discomfort coupled with abdominal pain and shortness of breath. He received aspirin, clopidogrel, and heparin before arriving at our emergency department. A splenectomy was performed for the patient, and he recovered well. Despite the rarity of spontaneous splenic rupture, physicians must consider it while evaluating elderly patients who are experiencing abdominal pain while on anticoagulants. Splenic rupture should always be considered, and early diagnosis is essential for a better outcome.

Impact of triage nurses' recognition of acute coronary syndrome on patients' clinical outcomes: A retrospective study.

BACKGROUND: Triage nurses' pivotal role in initial assessment makes their competence crucial. However, the specific impact on Acute Coronary Syndrome (ACS) recognition and outcomes remains unclear in Jordanian healthcare. Understanding this relationship could enhance ACS management and patient outcomes in Jordanian Emergency Departments (EDs). OBJECTIVE: To assess how triage nurses' recognition of ACS diagnosis affects patient outcomes in Jordan. METHODS: This retrospective study examined records of 150 ACS patients admitted to the coronary care unit (CCU). Data extraction assessed triage nurses' accuracy in recognizing ACS symptoms and the timelines for diagnosis procedures (e.g., electrocardiogram [ECG]) and treatment provision (e.g., thrombolytic) based on triage decisions. It also evaluated the impact on treatment outcomes, including length of stay in the ED and hospital. Multiple linear regression analyses quantified the influence of under-triage on treatment outcomes. RESULTS: The sample comprised 150 patients. Most were female (78.7%), aged 45-59.9 years (37.3%). ACS classifications: unstable angina (52.0%), STEMI (38.0%), NSTEMI (10.0%). The study included a cohort of ACS patients, with findings indicating varying degrees of under-triage by triage nurses. Analysis of timelines revealed significant delays in diagnosis and treatment initiation for patients subjected to under-triage. Multiple linear regression analyses demonstrated a robust association between under-triage and prolonged time to essential treatment outcomes, including delays in physician assessment, ECG performance, thrombolytic administration, and extended ED length of stay. CONCLUSION: Triage nurses' knowledge and competency are crucial determinants of accurate ACS recognition and subsequent clinical outcomes for patients presenting to the ED in Jordan. Investing in ongoing education and training programs for triage nurses may lead to improved ACS recognition rates and better patient outcomes in Jordanian healthcare settings.

Repeated intentional foreign body ingestion, what can be done?

Repeated intentional foreign body ingestion (RIFBI) in patients with Emotionally Unstable Personality Disorder (EUPD) is a common clinical presentation to the emergency department. The relationship between repeated foreign body ingestion and a co-existent personality disorder diagnosis is complex, making it challenging to manage. Our institution implemented a novel interdisciplinary model of care for RIFBI as a way of improving health outcomes in this cohort of patients. Our observations following the model of care are presented herein. We encourage other health networks to adopt this model of care for managing RIBFI in EUPD.

The New Era of Cancer Cytogenetics and Cytogenomics.

The promises of the cancer genome sequencing project, combined with various -omics technologies, have raised questions about the importance of cancer cytogenetic analyses. It is suggested that DNA sequencing provides high resolution, speed, and automation, potentially replacing cytogenetic testing. We disagree with this reductionist prediction. On the contrary, various sequencing projects have unexpectedly challenged gene theory and highlighted the importance of the genome or karyotype in organizing gene network interactions. Consequently, profiling the karyotype can be more meaningful than solely profiling gene mutations, especially in cancer where karyotype alterations mediate cellular macroevolution dominance. In this chapter, recent studies that illustrate the ultimate importance of karyotype in cancer genomics and evolution are briefly reviewed. In particular, the long-ignored non-clonal chromosome aberrations or NCCAs are linked to genome or chromosome instability, genome chaos is linked to genome reorganization under cellular crisis, and the two-phased cancer evolution reconciles the relationship between genome alteration-mediated punctuated macroevolution and gene mutation-mediated stepwise microevolution. By further synthesizing, the concept of karyotype coding is discussed in the context of information management. Altogether, we call for a new era of cancer cytogenetics and cytogenomics, where an array of technical frontiers can be explored further, which is crucial for both basic research and clinical implications in the cancer field.

Acute Coronary Syndrome: Treatment Strategies and Outcomes in Patients Admitted to a Tertiary Care Hospital in Palestine.

Background: Acute coronary syndrome (ACS) is the leading cause of death worldwide despite advances in treatment and prevention measures. This study aimed to explore ACS treatment strategies (ischemia-guided vs early invasive) and risk factors among patients diagnosed with ACS in a tertiary care hospital in Palestine and to evaluate related outcomes regarding future events and standard clinical guidelines. Methods: This retrospective cohort study reviewed patient data from a Palestinian medical hospital. The study included 255 patients ≥ 18 years who were hospitalized between January 2021 and December 2021 and diagnosed with ACS. The data were analyzed using the Statistical Package for Social Science (SPSS). Results: 71% of the participants were males. The mean age was 59.59±11.56 years. Smoking, diabetes, and hypertension were the most common risk factors. Unstable angina (UA) was the most prevalent ACS type, accounting for 43.1% (110) of cases, whereas NSTEMI accounted for 39.2% (100) and STEMI accounted for 17.6% (45) of cases. An ischemic-guided strategy approach was used in 71% (181) of the patients. Upon discharge, the most prescribed medication classes were antiplatelets (97.6%), statins (87.1%), PPIs (72.5%), and antihypertensives (71.8%). Treatment strategies were selected according to the clinical guidelines for most ACS types. Conclusion: ACS management in Palestine continues to evolve to overcome barriers, decrease patient mortality, and decrease hospital stay. UA and NSTEMI were the most common ACS diagnoses at admission, and the ischemic strategy was the most common modality. The findings of this study call for an increased awareness of CVD risk factors, resource availability, and adherence to clinical guidelines to improve patient outcomes and community health.
