Endovascular thrombectomy for DAWN- and DEFUSE-3 ineligible acute ischemic stroke patients: a systematic review and meta-analysis.

BACKGROUND: Endovascular therapy (EVT) has been proven beneficial for treating acute ischemic strokes (AIS) with large vessel occlusion (LVO). Recent trials of DAWN and DEFUSE-3 have extended the treatment window to 6-24 h, sparking investigations into EVT outcomes for patients not eligible for DAWN/DEFUSE-3 criteria. PURPOSE: To assess the outcomes of endovascular therapy (EVT) for late-window anterior circulation large vessel occlusion (LVO) in acute ischemic stroke patients, comparing DAWN/DEFUSE-3 eligible (DD) and ineligible (NDND) groups. METHODS: This systematic review and meta-analysis examined EVT outcomes for patients with late-window anterior circulation LVO beyond 6 h. We categorized patients as DAWN/DEFUSE-3 eligible (DD) and ineligible (NDND). Our search covered PubMed, Embase, Web of Science, and Scopus. A total of 464 records were initially identified. After duplicate removal, 298 studies were screened. Nine studies were included and analyzed. Our analysis focused on study characteristics, baseline comparisons, risk of bias, and outcomes. RESULTS: Baseline characteristics showed comparable age, gender, most comorbidities, NIHSS score, and ASPECTS between DAWN/DEFUSE-3 eligible (DD) and ineligible (NDND) patients. NDND patients' history showed a higher rate of atrial fibrillation and larger infarct volumes on baseline imaging. Successful reperfusion rates (TICI 2b-3) were similar between DD and NDND with 354 out of 469 in the DD group and 364 out of 459 in the NDND group (OR = 0.86; 95% CI 0.40, 1.84; p = 0.689), though with significant heterogeneity (I2 = 73%; P = 0.002). The proportion of patients with distal occlusions was significantly higher in the NDND group as compared to the DD group (137 (39.4%) of 347 patients versus 47 (11%) of 428 patients, respectively), with significant heterogeneity across studies (I2 = 85%, p = 0.023). Functional independence at 90 days (mRS 0-2) showed no significant difference between groups with 259 out of 802 in the DD group and 197 out of 668 in the NDND group (OR = 1.12; 95% CI 0.77, 1.63; p = 0.552) but also exhibited notable heterogeneity (I2 = 46%, p = 0.063). Symptomatic intracranial hemorrhage (sICH) rates were lower in DD with 14 out of 309 in the DD group and 47 out of 400 in NDND group (OR = 0.49; 95% CI 0.25, 0.93; p = 0.029) as compared to the NDND patients, showing no heterogeneity (I2 = 0%, p = 0.552). 90-day mortality was lower in DD with 43 out of 304 in the DD group and 107 out of 399 in the NDND group (OR = 0.55; 95% CI 0.37, 0.82; p = 0.004) as compared to NDND patients, with no significant heterogeneity (I2 = 0%, p = 0.536). CONCLUSION: This meta-analysis demonstrates equivalent rates of functional independence between DD and NDND patients. However, the high proportion of distal occlusions and higher rates of sICH and mortality in NDND patients suggest caution in offering mechanical thrombectomy to DAWN/DEFUSE-3 ineligible patients. A more flexible approach to EVT eligibility criteria could benefit select patients in real-world practice. Nonetheless, further research is needed to identify which patients would benefit from expanded EVT eligibility criteria.

The efficacy and safety of pre-hospital plasma in patients at risk for hemorrhagic shock: an updated systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVE: Plasma is a critical element in hemostatic resuscitation post-injury, and its prompt administration within the prehospital setting may reduce the complications resulting from hemorrhage and shock. Our objective is to assess the efficacy and safety of prehospital plasma infusion in patients susceptible to hemorrhagic shock. METHODS: We conducted our study by aggregating randomized controlled trials (RCTs) sourced from PubMed, EMBASE, Scopus, Web of Science, and Cochrane CENTRAL up to January 29, 2023. Quality assessment was implemented using the Cochrane RoB 2 tool. Our study protocol is registered in PROSPERO under ID: CRD42023397325. RESULTS: Three RCTs with 760 individuals were included. There was no difference between plasma infusion and standard care groups in 24-h mortality (P = 0.11), 30-day mortality (P = 0.12), and multiple organ failure incidences (P = 0.20). Plasma infusion was significantly better in the total 24-h volume of PRBC units (P = 0.03) and INR on arrival (P = 0.009). For all other secondary outcomes evaluated (total 24-h volume of packed FFP units, total 24-h volume of platelets units, massive transfusion, vasopressor need during the first 24 h, any adverse event, acute lung injury, transfusion reaction, and sepsis), no significant differences were observed between the two groups. CONCLUSION: Plasma infusion in trauma patients at risk of hemorrhagic shock does not significantly affect mortality or the incidence of multiple organ failure. However, it may lead to reduced packed red blood cell transfusions and increased INR at hospital arrival.

Successful coil embolization of a ruptured pseudoaneurysm of the superior gluteal artery after a percutaneous awake robot-assisted sacroiliac joint fusion: illustrative case.

BACKGROUND: Robot-assisted sacroiliac joint (SIJ) fusion has gained popularity, but it carries the risk of complications such as injury to the superior gluteal artery (SGA). The authors present the case of an awake percutaneous robot-assisted SIJ fusion leading to an SGA pseudoaneurysm. OBSERVATIONS: An 80-year-old male, who had undergone an awake percutaneous robot-assisted SIJ fusion, experienced postoperative left hip pain and bruising. Subsequent arteriography demonstrated an SGA branch pseudoaneurysm requiring coil embolization. LESSONS: An SGA injury, although uncommon (1.2% incidence), can arise from percutaneous screw placement, aberrant anatomy, or hardware contact. Thorough preoperative imaging, precise robot-assisted screw insertion, and soft tissue protection are crucial to mitigate risks. Immediate angiography aids in prompt diagnosis and effective intervention. Comprehensive knowledge of anatomical variants is essential for managing complications and optimizing preventative measures in robot-assisted SIJ fusion.

The Egyptian journey from having the highest prevalence of hepatitis C virus to being the first to achieve "gold tier" in conquering the disease.

Hepatitis C virus (HCV) is a major global health concern, particularly in Egypt, due to historic schistosomiasis control efforts that inadvertently led to widespread HCV transmission. This study aimed to evaluate the efficacy of Egypt's national strategies in controlling and reducing the prevalence of HCV, including introducing sofosbuvir and implementing the "100 Million Healthy Lives" campaign. The approach includes a review of epidemiological data, an analysis of the national HCV control strategies implemented, and an assessment of their outcomes, focusing on the period from 2006 to 2022. Significant milestones were achieved, including a drastic reduction in new HCV infections from 300 per 100,000 in 2014 to 9 per 100,000 in 2022 and successful treatment of over 4 million people. Egypt has become the first country in the world to achieve the "gold tier" status based on World Health Organization criteria on the path to eradication of HCV. Egypt's comprehensive approach can serve as a model for similar endemic regions. Other nations with high HCV prevalence might benefit from adopting similar multidimensional strategies, emphasizing prevention and treatment.

Relation between non-alcoholic fatty liver disease and carotid artery intimal media thickness as a surrogate for atherosclerosis: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD), characterized by hepatic steatosis without heavy alcohol consumption or other chronic conditions, encompasses a spectrum from non-alcoholic fatty liver to non-alcoholic steatohepatitis leading to cirrhosis. This analysis aimed to investigate the correlation between NAFLD and carotid intimal media thickness (C-IMT), a non-invasive surrogate for atherosclerosis. METHODOLOGY: Database searches, including PubMed, EMBASE and Cochrane Library, yielded studies up to April 2023. Included were studies exploring the NAFLD-C-IMT relationship in populations aged >18 years. Exclusions comprised non-English papers, those involving animals or pediatric populations and studies lacking control groups. RESULTS: No statistical significance was noted between mild and moderate NAFLD compared to the control group regarding C-IMT [95% confidence intervals (CI): -0.03, 0.12] and (95% CI: -0.03, 0.21), respectively. There was a statistically significant difference only in the Severe NAFLD group ( P value 0.03). NAFLD with and without metabolic syndrome showed statistically significant differences compared to control regarding C-IMT (95% CI: 0.04, 0.12) and (95% CI: 0.01, 0.07), respectively. Fifty-nine studies were mentioned without classification of NAFLD severity and revealed a high statistically significant difference between NAFLD and controls regarding C-IMT with (95% CI: 0.09, 0.12, P < 0.00001). Stratified analysis according to sex was done in two studies and revealed statistical differences between NAFLD and control regarding C-IMT in both groups. CONCLUSION: This meta-analysis underscores a significant association between NAFLD and increased C-IMT, emphasizing the importance of assessing C-IMT in NAFLD patients to identify cardiovascular risk and tailor therapeutic interventions for improved patient outcomes.

Common design and data elements on rectal artery embolization for treatment of symptomatic internal hemorrhoidal disease: an interactive systematic review of clinical trials.

BACKGROUND: Internal hemorrhoids (IH) is a common medical condition that can result in morbidity secondary to bleeding and discomfort. Treatment for IH has traditionally consisted of dietary and conservative medical management, focal treatments including banding and sclerotherapy or hemorrhoidectomy. Recently, rectal artery embolization (RAE) has been studied as a potential treatment for bleeding predominant IH. We performed a common design and data element analysis of studies that report on RAE. MATERIALS AND METHODS: We conducted a qualitative systematic literature review for rectal artery embolization (RAE) for symptomatic hemorrhoidal disease. The screening process involved five online databases (PubMed, Embase, Google Scholar, DOAJ, and Scopus). Additionally, ClinicalTrials.gov was examined for active, unpublished completed studies. The initial search yielded 2000 studies, with 15 studies meeting the inclusion criteria after screening and assessment. The included studies comprised one RCT, one case series, one pilot study and 12 cohort studies. RESULTS: The population analysis revealed a male predominance across all studies, with varying cohort sizes. The baseline Goligher hemorrhoid grade was utilized in 80% of studies. The majority (73.3%) employed a transfemoral approach, and coils were the primary embolic material in 60% of studies, 26.6% were combination of coils and particles, and 6.6% were particles only. Patient selection criteria highlighted RAE's applicability for high surgical risk patients and those with anemia, chronic hematochezia, or treatment-refractory cases. Exclusion criteria emphasized factors such as previous surgeries, colorectal cancer, rectal prolapse, acute hemorrhoidal complications, and contrast allergy. Study designs varied, with cohort studies being the most common (12/15; 80%). Procedural details included the use of metallic coils and detachable micro-coils, with a high technical success rate reported in most studies ranging from 72 to 100%. The follow-up ranged from 1 to 18 months. The majority of studies reported no major immediate or post-procedural complications. CONCLUSION: While all studies focused on RAE as a treatment for IH, there was a great degree of heterogeneity among included studies, particularly regarding inclusion criteria, exclusion criteria, outcomes measures and timeframe. Future literature should attempt to standardize these design elements to help facilitate secondary analyses and increase understanding of RAE as a treatment option.
