Assessment of Reason for Exam Imaging Reporting and Data System (RI-RADS) in inpatient diagnostic imaging referrals

ObjectivesTo test the Reason for Exam Imaging Reporting and Data System (RI-RADS) in assessing the quality of radiology requests in an Italian cohort of inpatients; to evaluate the interobserver reliability of RI-RADS.MethodsA single-center quality care study was designed to retrospectively identify consecutive radiology request forms for computed tomography, magnetic resonance imaging, and conventional radiography examinations. One radiologist scored the requests using the RI-RADS. The association between RI-RADS and clinical request variables (urgent request, on-call requests, indication for imaging, requesting specialty, imaging modality, and body region) was evaluated. We calculated interobserver agreement between four readers in a subset of 450 requests.ResultsWe included 762 imaging requests. RI-RADS grades A (adequate request), B (barely adequate request), C (considerably limited request), D (deficient request), and X were assigned to 8 (1%), 49 (7%), 237 (31%), 404 (53%), and 64 (8%) of cases, respectively. In the multivariate analysis, the indication for imaging, body region, and requesting specialty significantly influenced the RI-RADS. Indications for imaging with a high risk of poor RI-RADS grade were routine preoperative imaging and device check requests. The upper extremity was the body region with the highest risk of poor RI-RADS grade. Requesting specialties with a high risk of poor RI-RADS grade were cardiovascular surgery, intensive care medicine, and orthopedics. The analysis of the interobserver agreement revealed substantial agreement for the RI-RADS grade.ConclusionThe majority of radiology exam requests were inadequate according to RI-RADS, especially those for routine imaging. RI-RADS demonstrated substantial reliability, suggesting that it can be satisfactorily employed in clinical settings.Critical relevant statementThe implementation of RI-RADS can provide a framework for standardizing radiology requests, thereby enabling quality assurance and promoting a culture of quality improvement.Key PointsRI-RADS aims to grade the completeness of radiology requests.Over half of the imaging requests were RI-RADS D grade; RI-RADS demonstrated substantial reliability.Most radiology requests were inadequate and RI-RADS could classify them in clinical practice.Graphical

Clinical Characteristics and Outcomes in Patients with Ruptured Middle Cerebral Artery Aneurysms: A Multicenter Study in Northern China.

The long-term prognosis of ruptured middle cerebral artery aneurysms (MCAAs) in northern China remains unclear. The aim of this study is to analyze the epidemiological characteristics and long-term outcomes of ruptured MCAAs in northern China. We included patients who were consecutively admitted for ruptured MCAAs to 12 tertiary care centers in northern China from January 2017 to December 2020. Kaplan‒Meier curves were used to compare survival in hazard strata. The Cox proportional hazards model was used to analyze risk factors and mortality risk, whereas logistic regression was used to identify factors influencing 2-year survival. Subgroup analyses were performed to verify the robustness of the results. Data on 959 patients with ruptured MCAAs were analyzed; 16.4% of these patients had ruptured intracranial aneurysms (RIAs) and were registered in the Chinese cerebral aneurysm database. The mean follow-up duration was 3.0years (range 0-6.2years). The 3-month and 2-year mortality rates were 15.5% and 18.2%, respectively. The risk factors for mortality were identified via Cox regression and were as follows: age > 70years, previous stroke, combined intracerebral hemorrhage (ICH)/intraventricular hemorrhage (IVH), poor Hunt and Hess grade, multiple aneurysms, and conservative treatment (CT). The positive association between the risk of death and CT was consistent across subgroups. According to logistic regression, hypertension, previous stroke, combined ICH/IVH, Hunt and Hess grade, and WFNS (World Federation of Neurological Surgeons) score were identified as factors negatively influencing 2-year survival. We detail the epidemiologic characteristics and long-term outcomes of MCAAs. The risk factors for mortality included age > 70years, previous stroke, combined ICH/IVH, poor Hunt and Hess grade, and multiple aneurysms. Compared with microsurgical treatment (MST), CT is associated with an increased risk of mortality, while the risk of mortality associated with endovascular treatment (EVT) is not significantly different. Two-year survival was associated with hypertension, previous stroke, ICH/IVH, and poor grades at admission.

Downstaging Effect Rather than the Full Intended Cycles of Perioperative Chemotherapy Determines the Value of Adjuvant Chemotherapy in Gastric Cancer.

Perioperative chemotherapy is the standard treatment modality for locally advanced gastric cancer. However, the efficacy and indication of adjuvant chemotherapy in patients who have already received neoadjuvant chemotherapy remain unclear. This study aims to explore the association between adjuvant chemotherapy with patient prognosis in those who have received neoadjuvant chemotherapy plus D2 gastrectomy in a real-world setting, and whether this association is affected by the duration of neoadjuvant treatment. A total of 174 patients with cT3-4N+ gastric cancer who had received neoadjuvant chemotherapy plus D2 radical gastrectomy were included in the study. Kaplan-Meier curves and log-rank tests were used to assess and compare the survival outcomes between patients who received adjuvant therapy and those who did not. Patients who were younger age, had a lower American Society of Anesthesiologists (ASA) grade, did not experience postoperative complication, and received fewer than six cycles of neoadjuvant chemotherapy were more likely to receive adjuvant chemotherapy, rather than those with advanced ypTNM stage or poor tumor regression grade. Patients who received adjuvant therapy had a better overall survival (OS) (2-year OS rate 86.2% versus 64.1%, p=0.002). Adjuvant therapy was associated with longer survival in patients who remained ypTNM stage III despite receiving at least six cycles of neoadjuvant chemotherapy. However, there was no significant longer survival observed in patients with ypTNM stages 0-II receiving adjuvant chemotherapy, even when they received less than six cycles of neoadjuvant chemotherapy. Patients with locally advanced gastric cancer may still need adjuvant chemotherapy, even after receiving neoadjuvant chemotherapy. The value of adjuvant chemotherapy after neoadjuvant chemotherapy depends more on the actual downstaging effect achieved after neoadjuvant chemotherapy, rather than the completion of "full intended" cycles of perioperative treatment.

Identifying Patients at Increased Risk for Poor Outcomes Among Poor-Grade Aneurysmal Subarachnoid Hemorrhage Patients: The IPOGRO Risk Model

Background: A subarachnoid hemorrhage due to an aneurysmal rupture (aSAH) is a serious condition with severe neurological consequences. The World Federation of Neurosurgical Societies (WFNS) classification is a reliable predictor of death and long-term disability in patients with aSAH. Poor-grade neurological conditions on admission in aSAH (PG-aSAH) are often linked to high mortality rates and unfavorable outcomes. However, more than one-third of patients with PG-aSAH may recover and have good functional outcomes if aggressive treatment is provided. We developed a risk model called Identifying POor GRade Outcomes (IPOGRO) to predict 6-month mRS outcomes in PG-aSAH patients as a secondary analysis of a previously published study. Methods: All consecutive patients in poor-grade neurological conditions (WFNS IV-V) admitted to our institute from 2010 to 2020 due to aSAH were considered. Clinical and neuroradiological parameters were employed in the univariable analysis to evaluate the relationship with a 6-month modified Rankin Scale (mRS). Then, a multivariable multinomial regression model was performed to predict 6-month outcomes. Results: 149 patients with PG-aSAH were included. Most patients were surgically treated, with only 33.6% being endovascularly treated. The 6-month mRS score was significantly associated with clinical parameters on admission, such as lowered Glasgow Coma Scale (GCS), leukocytosis, hyperglycemia, raised Systolic Blood Pressure (SBP), greater Simplified Acute Physiology Score (SAPS II score), increased initial serum Lactic Acid (LA) levels, and the need for Norepinephrine (NE) administration. Neuroradiological parameters on the initial CT scan showed a significant association with a worsening 6-month mRS. The IPOGRO risk model analysis showed an association between a WFNS V on admission and a poor outcome (mRS 4-5), while raised SBP was associated with mortality. Conclusions: Our IPOGRO risk model indicates that PG-aSAH patients with higher SBP at admission had an increased risk of death at 6-month follow-up, whereas patients with WFNS grade V at admission had an increased risk of poor outcome but not mortality.

Liver Transplantation for the Cure of Neuroendocrine Liver Metastasis: A Systematic Review with Particular Attention to the Risk Factors of Death and Recurrence

Background/Objectives: Neuroendocrine neoplasms (NEN) are heterogeneous entities. Despite considerable advancement in the field, almost 50% of patients have metastatic disease, when liver transplantation (LT) is one of the possible treatments offering a cure in well-selected patients. Methods: The present study aims to systematically review all the literature from 2000 onwards on using LT for patients with NEN-LM, with particular attention to the risk factors of death and recurrence. Results: LT offers 5-year OS ranging from 52 to 74% and 5-year TFS rates ranging from 39 to 62%, with even better results published from 2009 onwards. The main risk factors for patient deaths are related to unfavorable primary tumor pathology, higher liver involvement, and simultaneous LT and primary resection. Similarly, recurrence is higher related to poor tumor grade and differentiation, and in the case of an older recipient age. Conclusions: Applying uniform criteria and a more in-depth understanding of the relevant prognostic factors contribute to a better selection of candidates for curative LT due to NEN metastases. LT for unresectable or liver-restricted NENs has a relevant place in the treatment algorithm and has achieved excellent results in recent decades, but more international efforts are needed to further improve outcomes.

Unaccompanied homelessness among high school students across ten states: prevalence and risk in multiple domains

ABSTRACT Unaccompanied homelessness during adolescence is a risk factor for varied poor outcomes, yet enumeration efforts struggle to provide feasible results and few analyses consider how risk might differ for this group. We consider data from the 2019 Youth Risk Behavior Survey from 10 states that asked about unaccompanied homelessness and sleeping arrangement. Students who experienced any form of homelessness were at higher risk for poor outcomes and other risk experiences. Few students reported both unaccompanied homelessness and usually sleeping in a homeless situation. Youth experiencing unaccompanied homelessness had higher risk for alcohol problems and lower risk for severe drug use and poor grades compared to students who experienced other forms of homelessness; otherwise they had similar levels of risk for poor outcomes. Results are consistent with the view that students who experience unaccompanied homeless are a distinguishable subpopulation of students who experience homelessness and are at high levels of risk of poor outcomes.

Age-Related Differences in Clinical Characteristics and Outcomes of Aneurysmal Subarachnoid Hemorrhage: A Retrospective Study of 657 Patients

Aneurysmal subarachnoid hemorrhage (aSAH) has an incidence of 6-7 per 100,000 person-years. Despite advancements in treatment, 26% of patients die, and 19% remain dependent post-hemorrhage. Long-term neuropsychological sequelae affect about half of the survivors, significantly impacting their quality of life. This study aims to assess aSAH characteristics and identify predictive factors of clinical outcomes in young patients. A retrospective study analyzed 657 aSAH patients treated at two South Korean medical centers from January 2011 to December 2023. Data on demographics, comorbidities, smoking history, clinical grades, aneurysm size and location, and outcomes were collected. Outcomes were classified using the modified Rankin Scale (mRS), with scores ≤2 indicating good outcomes. The cohort included 233 men and 424 women (male-to-female ratio 1:1.8). Most patients were middle-aged (74.4%), followed by young (16.7%) and old (8.8%) groups. Young patients exhibited male predominance (56.8%), lower hypertension (12.7%) and diabetes (1.8%) rates, and higher smoking rates (39.6%). Older patients had higher hypertension (44.6%) and diabetes (23.3%) rates, and were predominantly female (69.1%). Aneurysms in young patients were smaller (p=0.04). Multivariate analysis identified poor Hunt-Hess grade, permanent cerebral infarction, and aneurysmal recurrence or rebleeding as predictors of poor outcomes in young patients. Middle-aged patients had additional predictors, including diabetes and hydrocephalus. In older patients, only poor Hunt-Hess grade was significant. Young aSAH patients exhibit distinct characteristics and prognostic factors compared to older patients. Despite higher post-operative complications, young patients generally have better outcomes, emphasizing the need for age-specific management strategies in aSAH.

Comparison of laparoscopic hepatectomy and radiofrequency ablation for small hepatocellular carcinoma patients: a SEER population-based propensity score matching study.

This study was designed to compare the efficacy of laparoscopic hepatectomy (LH) and radiofrequency ablation (RFA) in terms of their therapeutic effect on small hepatocellular carcinoma (SHCC). The SEER database was employed to integrate SHCC patients who had received treatment with either LH (n = 1132) or RFA (n = 797). The LH group (n = 623) and the RFA group (n = 623) were matched with 1:1 propensity score matching (PSM) in order to reduce the possibility of selection bias. The Kaplan-Meier method and Cox proportional hazards regression method were employed to ascertain the prognostic factors associated with overall survival (OS) and disease-specific survival (DSS). Both before and after PSM, the 1, 3 and 5-years OS and DSS were significantly higher in the LH groups compared to the RFA group. Besides, for SHCC with tumor size ≤ 2cm (n = 418), even P values not reaching statistical significance, the survival curves were compatible with a superiority of LH over RFA for OS and DSS in overall (P = 0.054 and P = 0.077), primary SHCC (P = 0.110 and P = 0.058) and recurrent SHCC (P = 0.068 and P = 1.000) cohorts. In contrast, for SHCC with tumor size between 2 and 3 cm (n = 828), LH group always had a better OS and DSS in the all cohorts (all P < 0.05). In addition, higher AFP level, poor differentiation grade, recurrent tumor and treatment type were independent prognostic factors for OS, while poor differentiation grade, larger tumor size and treatment type were the independent prognostic factors for DSS (all P < 0.05). LH was associated with better OS and DSS than RFA in SHCC patients. Even in tumor size ≤ 2cm, LH still should be the first choice as its long-term survival benefits.

Emergency Surgical Management of Meningiomas: Factors Affecting Early Outcomes and Complications

Abstract Objective Intracranial meningiomas constitute a third of all brain tumors and are among the most common indications for neurosurgical procedures performed worldwide. Most meningiomas present with an indolent, longstanding history. However, the data on outcomes of emergency surgeries for meningioma is limited. This study aims to present our experience of urgent surgical intervention in patients with meningiomas presenting acutely. We also analyze the factors influencing early neurological outcomes and complications. Materials and Methods All nonelective meningioma surgeries done on an emergency basis between January 2015 and December 2019 were retrospectively reviewed. Patients' demography, clinical, and radiological details were recorded for analysis. The surgical procedure, complications, and follow-up outcomes were also included for statistical comparison. Results Forty-four patients qualified for the study with a mean age of 49.4 ± 13.4 years. The average presenting Glasgow Coma Scale (GCS) was 13; 47.7% of cases presented with altered sensorium. The most common lesion location was convexity (25, 56.8%), and the mean tumor volume was 74.1 ± 36.5 mL. Gross peritumor edema with mass effect was seen in 16 patients (36.4%). The mean Karnofsky Performance Status at 3 months' follow-up was 89.3 ± 18.2. Patient age and tumor size did not affect outcomes. The presenting GCS of &lt; 15 (odds ratio [OR] 8.8, confidence interval [CI] 0.95–80.72, p 0.03) and the occurrence of postoperative complications (OR 25.71, CI 2.65–249.2, p 0.001) were associated with unfavorable outcomes. Although not statistically significant, a poor tumor grade was also associated with worse clinical outcomes (p 0.20). Conclusion Emergency meningioma surgery has comparable outcomes and complication rates with routine elective procedures. Grade II/III meningiomas are more likely to present with acute neurological deterioration and carry a relatively worse prognosis. Poor presenting GCS and postoperative complications are the most critical factors associated with poor patient outcomes in our study.

The Effects of Adverse Life Events on Brain Development in the ABCD Study®: A Propensity-weighted Analysis.

Longitudinal studies of the effects of adversity on human brain development are complicated by the association of stressful events with confounding variables. To counter this bias, we apply a propensity-weighted analysis of the first two years of The Adolescent Brain Cognitive DevelopmentSM (ABCD) Study® data, employing a machine learning analysis weighted by individuals' propensity to experience adversity. Data included 338 resting-state functional connections from 7190 youth (46% female), divided into a training group (80%) and an independent testing group (20%). Propensity scores were computed using 390 variables to balance across two-year adverse life event exposures. Using elastic net regularization with and without inverse propensity weighting, we developed linear models in which changes in functional connectivity of brain connections during the two-year period served as predictors of the number of adverse events experienced during that same period. Haufe's method was applied to forward-transform the backward prediction models. We also tested whether brain changes associated with adverse events correlated with concomitant changes in internalizing or externalizing behaviors or to academic achievement. In the propensity-weighted analysis, brain development significantly predicted the number of adverse events experienced during that period in both the training group (ρ=0.14, p<0.001) and the independent testing group (ρ=0.10, p<0.001). The predictor indicated a general pattern of decreased functional connectivity between large-scale networks and subcortical brain regions, particularly for cingulo-opercular and sensorimotor networks. These network-to-subcortical functional connectivity decreases inversely associated with the development of internalizing symptoms, suggesting adverse events promoted adaptive brain changes that may buffer against stress-related psychopathology. However, these same functional connections were also associated with poorer grades at the two-year follow-up. Although cortical-subcortical brain developmental responses to adversity potentially shield against stress-induced mood and anxiety disorders, they may be detrimental to other domains such as academic success.

Increased brain volume in the early phase of aneurysmal subarachnoid hemorrhage leads to delayed cerebral ischemia.

To investigate the correlation between the swelling rate of brain volume within the first 48 h after aneurysmal subarachnoid hemorrhage and the subsequent development of delayed cerebral ischemia. A retrospective analysis was conducted on patients with spontaneous aneurysmal subarachnoid hemorrhage admitted to the Neurosurgery Intensive Care Unit of the First Affiliated Hospital of Chongqing Medical University between January 2020 and January 2023. The clinical data, treatment outcomes, and imaging data were analyzed. Brain volume was evaluated using 3D-Slicer software at two time points post-hemorrhage: within the first 24 h and between 24 and 48 h. The swelling rate of brain volume was defined as the ratio of the absolute difference between two measurements to the smaller of values. Patients were categorized into two groups based on established diagnostic criteria of delayed cerebral ischemia. Univariate and multivariate logistic regression analyses were performed to identify factors influencing delayed cerebral ischemia. A total of 140 patients were enrolled in this study. 46 patients experienced delayed cerebral ischemia after bleeding. The swelling rate of brain volume was larger in the DCI group (10.66 ± 8.45) compared to the non-DCI group (3.59 ± 2.62), which showed a statistically significant difference. Additionally, advanced age, smoking history, history of hypertension, loss of consciousness, poor Hunt-Hess grade, high mFisher score, brain volume within 24 h, and IVH were also statistically different between the two groups. Multivariate logistic regression analysis revealed that the swelling rate of brain volume was an independent risk factor for DCI with adjusting the advanced age, smoking history, history of hypertension, poor Hunt-Hess grade, high mFisher score, brain volume within 24 h, and IVH. Brain volume significantly increased in patients with aneurysmal subarachnoid hemorrhage during the early phase (within 48 h post-onset). The larger swelling rate of brain volume is an independent risk factor for the development of delayed cerebral ischemia, and it may hold significant predictive value for the incidence of delayed cerebral ischemia.

Evaluating the Impact of Haryana’s Edible Oil Plant Resources on Human Health

Oil is odorless compound of herbs and spices and has been used for centuries to flavor and preserve foods, medicines and perfumes. There are many aromatic plant species in the Lamiaceae and Apiaceae plant families. Edible oils are produced in Haryana and is used for its beneficial effects on human health. The most common crops include peanuts, mustard, sunflower seeds, sesame seeds, soyabeans, wheat (rice bran), sunfflower, cotton, flaxseeds, etc. Takes place. Essential oils have many health benefits. The oil contains antioxidants. Vitamin E, plant sterols and polyunsaturated fatty acids (PUFA), which can lower cholestrol and prevent chronic diseases such as heart disease, diabetes and cancer. Fatty oils are divided into three types: drying and semi-drying oil, non-drying oil, and vegetable oil. The refined grades of drying and semi-drying oils are used to make edible oils, while the poorer grades are used to make soaps, varnishes, paints, candles, and other similar products. Oils contain a variety of bioactive chemicals (e.g., terpenoids), which have most biological effects and qualities in addition to their scent and flavor. Antibacterial, antifungal, antioxidant, insecticide, anthelminthic, acaricidal, larvicidal, anthelmintic, anti-inflammatory, cytotoxic, antibacterial, antiseptic, and local anaesthetic are just few of them.Oil compounds, such as geraniol, have recently demonstrated potential anticancer actions in cancer cells, triggering growth inhibition and death.

Under recognized yet a clinically relevant impact of aneurysm location in Distal Anterior Cerebral Artery (DACA) aneurysms: insights from a contemporary surgical experience.

Aneurysms of the distal anterior cerebral artery (DACA) are rare but surgically challenging. Despite a known therapeutic implication of the aneurysm location on the DACA territory, the literature is unclear about its clinical and prognostic significance. Our surgical experience over the last 5 years was reviewed to compare the clinical, operative, and outcome characteristics between aneurysms located below the mid portion of the genu of the corpus callosum (called proximal aneurysms) to those distal to this point (called distal aneurysms). A prognostic factor analysis was done using uni and multivariable analysis. A total of 34 patients were treated (M: F = 1:2.3). The distal group had a higher frequency of poor clinical grade at presentation (n = 9, 47.4%) in contrast to (n = 2, 13.3%) proximal aneurysms (p = 0.039). Despite an overall tendency for a delayed functional improvement in these patients, the results were mainly due to favorable outcomes in the proximal group (favourable functional outcomes at discharge and at last follow-up being 80% and 86.7% respectively). On the multivariable analysis, only WFNS grade (> 2) at presentation (OR = 13.75; 95CI = 1.2-157.7) (p = 0.035) and application of temporary clips (AOR = 34.32; 95CI = 2.59-454.1) (p = 0.007), both of which were more in the distal group, independently predicted a poor long term functional outcome. Thus, the aneurysm location impacts the preoperative clinical grade, the intraoperative aneurysm rupture risk rate as well as the temporary clipping requirement. A combination of these factors leads to worse short and long-term functional outcomes in the distal DACA aneurysms.

The Influence of EFL Apprehension in Speaking Performance

The influence of EFL apprehension on speaking performance is a significant area of study in language learning. Empirical studies reveal that anxiety among EFL students is influenced by variables such as communication anxiety, fear of receiving a poor grade, and low self-esteem. during speaking activities. Speech anxiety among ESL/EFL learners can impact their oral communication skills negatively, leading to avoidance and withdrawal from speaking activities in the classroom. Language anxiety, specifically related to speaking, can hinder students' willingness to engage in foreign language acquisition and affect their speaking performance negatively .Research have indicated a connection between EFL students' oral communication anxiety and communication proficiency,highlighting the importance of addressing anxiety to enhance language proficiency.

Factors Affecting Outcome in Surgically Clipped Ruptured Anterior Circulation Aneurysms – A Retrospective Analysis

Abstract Introduction: Ruptured cerebral aneurysm is a life-threatening condition that requires urgent medical attention. Failure to diagnose, delay in admission to a neurosurgical centre and lack of facilities could lead to poor surgical outcomes. Aim: The purpose of this study was to identify the factors that predict the outcome of patients undergoing a surgical clipping of ruptured anterior circulation aneurysms. Materials and Methods: This was a single-centre retrospective study with review of medical records of 306 patients, who were surgically treated for ruptured intracranial aneurysms in a tertiary care centre from January 2011 to June 2018. Information collected were the patient demographic data, Glasgow Coma Scale prior to surgery, World Federation of Neurosurgical Societies Scale and timing between subarachnoid haemorrhage (SAH) ictus and surgery. The outcomes at discharge and 6 months post-surgery were assessed using the modified Rankin Scale (mRS). Only cases of proven ruptured aneurysmal SAH involving anterior circulation that underwent surgical clipping were included in the study. The data collected were analysed statistically. Results: The mean duration between ictus and time of surgery was found to be 9.89 days, maximum being 43 days. Patients with persisting disabilities (according to mRS) at the 1st month and 3rd month post-surgery had a mean duration of 16.69 and 16.95 days, from ictus to surgery. Conclusions: Delay in surgical clipping of anterior circulation aneurysms and poor grade at presentation were found to have unfavourable outcomes. Health education and training should be incorporated in primary healthcare setups regarding the identification of probable aneurysm rupture in early stage, so that prompt referral to higher centre can be carried out and delay in intervention be curtailed.

Outcomes following surgical clipping of re-ruptured previously untreated intracranial aneurysms.

Re-rupture of untreated intracranial aneurysm is a potentially life-threatening condition. Despite tremendous advances in the diagnosis and treatment of intracranial aneurysms, such events are not rare and continue to pose a management dilemma. In this study, we examined the clinical, radiological and treatment details of patients who underwent microsurgical clipping for re-rupture of previously untreated intracranial aneurysms. Re ruptures were categorized as early and late re ruptures (< or > 7 days of inter ictus interval respectively). Modified Rankin Score (mRS) was used for functional outcome assessment and logistic regression analysiswas used to test the predictors of long-term outcome. Re-ruptured intracranial aneurysms comprised 5% (n = 32/637) of the aneurysm clippings done at our center in this time span. The mean mRS score at discharge and at last follow-up were 3 and 3.04 respectively. Twenty-four (75%) patients were alive at a mean follow-up of 36 months. Early re-ruptures were associated with worse mean mRS scores at discharge (3.9 vs 2.5, p = 0.03) including the perioperative deaths (n = 4, 12.5%). The functional status at discharge and a poor preoperative clinical grade predicted apoor long-term outcome. Therefore, the long-term outcomes are primarily dependent on the short-term outcomes and to a lesser extent, the clinical grade at presentation. Those presenting with poor preoperative clinical grade, especially in the setting of an early re rupture, have a very poor prognosis and do not benefit from surgery.

Measuring The Level of The Hormone Progesterone on The Day of Transfer of Fresh and Frozen Embryos and Its Impact on Pregnancy Outcomes

Objective: Prediction of the effect of the hormone progesterone on pregnancy results that measured on the day of transfer of fresh and frozen embryos. Method: This research at reproductive centres in Baghdad from May 2022 to April 2023 examined how serum progesterone levels affect embryo transfers in ICSI procedures in 100 fresh or frozen cycle women. The study examined clinical data and endometrial preparation techniques to determine if progesterone levels affect pregnancy rates. Data were analysed using SPSS to determine how pre-transfer hormonal levels affected implantation and pregnancy outcomes. Participants were selected according on inclusion and exclusion criteria. The study shows that progesterone is essential for IVF embryo transfers. Results: Compared to frozen cycles in females, fresh cycles had greater mean age and progesterone levels but lower COC number and 2PN levels, with no changes in BMI, MII, or injectable MII. Frozen cycles produced more good-grade embryos, whereas fresh cycles produced more fair-grade embryos. There were no differences in the number of "C" embryos. Fresh cycle groups had greater pregnancy rates (59.1%) than frozen cycle groups (38.9%), but progesterone levels did not change between cycle types. Conclusion: The study found that fresh cycles include older participants, greater progesterone but lower COC and 2PN levels, and higher pregnancy rates than frozen cycles. BMI, MII levels, embryo count, poor grade "C" embryos, and progesterone levels associated to pregnancy outcomes did not differ across groups.

First step results from a phase II study of a dendritic cell vaccine in glioblastoma patients (CombiG-vax).

Glioblastoma (GBM) is a poor prognosis grade 4 glioma. After surgical resection, the standard therapy consists of concurrent radiotherapy (RT) and temozolomide (TMZ) followed by TMZ alone. Our previous data on melanoma patients showed that Dendritic Cell vaccination (DCvax) could increase the amount of intratumoral-activated cytotoxic T lymphocytes. This is a single-arm, monocentric, phase II trial in two steps according to Simon's design. The trial aims to evaluate progression-free survival (PFS) at three months and the safety of a DCvax integrated with standard therapy in resected GBM patients. DCvax administration begins after completion of RT-CTwith weekly administrations for 4 weeks, then is alternated monthly with TMZ cycles. The primary endpoints are PFS at three months and safety. One of the secondary objectives is to evaluate the immune response both in vitro and in vivo (DTH skin test). By December 2022, the first pre-planned step of the study was concluded with the enrollment, treatment and follow up of 9 evaluable patients. Two patients had progressed within three months after leukapheresis, but none had experienced DCvax-related G3-4 toxicities Five patients experienced a positive DTH test towards KLH and one of these also towards autologous tumor homogenate. The median PFS from leukapheresis was 11.3 months and 12.2 months from surgery. This combination therapy is well-tolerated, and the two endpoints required for the first step have been achieved. Therefore, the study will proceed to enroll the remaining 19 patients. (Eudract number: 2020-003755-15 https://www.clinicaltrialsregister.eu/ctr-search/trial/2020-003755-15/IT).

Improved Outcomes Among Octogenarians with Ruptured Aneurysms: Endovascular Treatment as Right-of-First-Refusal in the Second Post-trial Decade

BackgroundTreatment outcomes of octogenarians with aneurysmal subarachnoid hemorrhage (aSAH), are often considered poor. With ongoing advancements and experience in endovascular technology, we sought to evaluate the outcomes of octogenarians treated for aSAH in the second post-ISAT/BRAT trial decade. MethodA single-center database of aSAH was reviewed to identify patients aged 80 or above undergoing aneurysm treatment. Mortality and favorable neurological outcome (defined as mRS <3) were assessed among the series and compared across several subgroups. ResultsOctogenarian patients constituted 6% of the aSAH cohort (38/619) over the reviewed period. Twenty-one percent were high grade (Hunt-Hess IV-V). Endovascular treatment was the first-line modality in 90% of patients. During a median follow-up of 17 months, the overall mortality was 39%. Higher mortality was associated with poor Hunt-Hess grade (100% for Grade-V, 47% for III-IV, 13% for I-II, P=0.004) and non-independent baseline function status (100% mortality for non-independent vs. 28% for independent group, P=0.002). At last follow-up, 53% of patients achieved a favorable neurological outcome. The stratified rate was 80% in Hunt-Hess grade I-II and over 60% in patients with premorbid independent function status or less than 5 frailty components (P≤0.02 vs. poorer counterparts). ConclusionNeurological outcomes of octogenarian patients with aSAH are improving in the second post-trial decade, particularly given the preponderance of endovascular treatment. Baseline functional status and comorbidities of octogenarians should be considered in addition to the Hunt-Hess grade in prognostication.

Effects of Cement Dosage, Curing Time, and Water Dosage on the Strength of Cement-Stabilized Aeolian Sand Based on Macroscopic and Microscopic Tests.

Aeolian sand is distributed worldwide, exhibiting poor grading, low cohesion, and loose structure. Infrastructure construction in desert areas sometimes requires stabilization of the sand, with cement as the primary curing agent. This study first employed orthogonal experiments to evaluate critical factors, e.g., curing time, cement dosage, and water dosage, affecting the unconfined compressive strength (UCS) of the aeolian sand stabilized with cement (ASC). Each of the aforementioned factors were set at five levels, namely curing time (7, 14, 28, 60, and 90 days), cement dosage (3%, 5%, 7%, 9%, and 11%), and water dosage (3%, 6%, 9%, 12%, and 15%), respectively. The water and cement dosages were percentages of the mass of the natural aeolian sand. The results indicated that the sensitivity of the influencing factors on the UCS of ASC was cement dosage, curing time, and water dosage in descending order. The UCS of ASC positively correlated with curing time and cement dosage, while it first increased and then decreased with the water dosage increase. The optimal conditions were 90 days' curing time, 11% cement dosage, and 9% water dosage. The microscopic analyses of ASC using optical microscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD) revealed that hydration products enhanced strength by bonding loose particles and filling pores, thereby improving compaction. The quantity and compactness of hydration products in the aeolian-cement reaction system increased with the increases in cement dosage and curing time, and low water dosage inhibited the hydration reaction. This study can provide insights into the stabilization mechanism of aeolian sand, aiding infrastructure development in desert regions.
