RESUMEN

BACKGROUND: Breast cancer continues to pose a significant public health challenge, with its incidence and disproportionate impact on underserved populations in the United States. The relationship between obesity and clinicopathological characteristics at presentation remains a critical area of investigation. Safety-net hospitals caring for underserved communities provide a unique setting to explore these associations. This study seeks to explore a critical gap in knowledge on obesity and breast cancer characteristics in underserved populations in the United States. MATERIALS AND METHODS: In this retrospective study, 927 breast cancer patients were included. Analysis was conducted to assess the association between body mass index (BMI), age of diagnosis, tumor clinicopathologic characteristics, and molecular types stratified by menopausal status at diagnosis. Analysis was performed using the Statistical Package for Social Sciences version 29. RESULTS: A significant association was found between BMI and menopausal status (P < .05). Disease stage at presentation was significantly associated with BMI (P < .05). Further investigation into BMI categories and tumor characteristics revealed a significant correlation in postmenopausal women, with obesity linked to tumor size and lymph node status (P < .05). No significant associations were observed between HER-2 status, ER/PR status, and obesity in either premenopausal or postmenopausal groups. CONCLUSION: This observational retrospective hypothesis-generating study revealed the association between obesity and disease stage and menopause status at diagnosis. In postmenopausal patients, obesity correlated with larger tumor size and advanced lymph node disease involvement. Additionally, ethnic variations were observed, with a higher prevalence of obesity among African American patients.

RESUMEN

Background: Bilothorax is defined as the presence of bile in the pleural space. It is a rare condition, and diagnosis is confirmed with a pleural fluid-to-serum bilirubin ratio of >1. Methods: The PubMed, Embase, Google Scholar, and CINAHL databases were searched using predetermined Boolean parameters. The systematic literature review was done per PRISMA guidelines. Retrospective studies, case series, case reports, and conference abstracts were included. The patients with reported pleural fluid analyses were pooled for fluid parameter data analysis. Results: Of 838 articles identified through the inclusion criteria and removing 105 duplicates, 732 articles were screened with abstracts, and 285 were screened for full article review. After this, 123 studies qualified for further detailed review, and of these, 115 were pooled for data analysis. The mean pleural fluid and serum bilirubin levels were 72 mg/dL and 61 mg/dL, respectively, with a mean pleural fluid-to-serum bilirubin ratio of 3.47. In most cases, the bilothorax was reported as a subacute or remote complication of hepatobiliary surgery or procedure, and traumatic injury to the chest or abdomen was the second most common cause. Tube thoracostomy was the main treatment modality (73.83%), followed by serial thoracentesis. Fifty-two patients (51.30%) had associated bronchopleural fistulas. The mortality was considerable, with 18/115 (15.65%) reported death. Most of the patients with mortality had advanced hepatobiliary cancer and were noted to die of complications not related to bilothorax. Conclusion: Bilothorax should be suspected in patients presenting with pleural effusion following surgical manipulation of hepatobiliary structures or a traumatic injury to the chest. This review is registered with CRD42023438426.

RESUMEN

Background and Aim: Obesity affects nearly 650 million adults worldwide, and the prevalence is steadily rising. This condition has significant adverse effects on cardiovascular health, increasing the risk of hypertension, coronary artery disease, heart failure, and atrial fibrillation (AF). While anticoagulation for obese patients with AF is a well-established therapy for the prevention of thromboembolism, the safety and efficacy of different anticoagulants in this specific population are not well explored. This meta-analysis aimed to compare direct oral anticoagulants (DOAC) to vitamin K antagonists in obese populations with AF. Methods: The PRISMA guidelines were followed for this meta-analysis, registered in PROSPERO (CRD42023392711). PubMed, PubMed Central, Embase, Cochrane Library, and Scopus databases were searched for relevant articles from inception through January 2023. Two independent authors screened titles and abstracts, followed by a full-text review in Covidence. Data were extracted in Microsoft Excel and analyzed using RevMan v5.4 using odds ratio as an effect measure. Results: Two thousand two hundred fifty-nine studies were identified from the database search, and 18 were included in the analysis. There were statistically significant reductions in the odds of ischemic and hemorrhagic stroke in the DOAC group compared with the VKA group (OR 0.70, CI 0.66-0.75) and (OR 0.47, CI 0.35-0.62), respectively. In addition, the DOAC group exhibited lower odds of systemic embolism (OR 0.67, CI 0.54-0.83), major bleeding (OR 0.62, CI 0.54-0.72), and composite outcome (OR 0.72, CI 0.63-0.81). Conclusion: Based on the findings from this meta-analysis, DOACs demonstrate superior safety and efficacy in obese patients with AF compared with VKAs. These results may have significant implications for guiding anticoagulation strategies in this patient population.

RESUMEN

Background: There has been recent growing interest in the use of conduction system pacing (CSP) for both bradycardia and heart failure indications. There remains a paucity of data, however, regarding complications related to the intraventricular septum associated with CSP implant and the management of these events. Case summary: We present a case of a patient with non-ischemic dilated cardiomyopathy presenting for cardiac resynchronization therapy in whom left bundle branch area pacing was complicated with interventricular septal perforation and managed intra-procedurally with repositioning of the lead to provide His bundle pacing (HBP) for QRS correction of underlying left bundle branch block. Post-procedure echocardiography did not show persistent ventricular septal defect. Left ventricular ejection fraction improved from 13% four months before implant to 30% at 32 months post-implant. Corrective HBP pacing thresholds showed a rise at 3-year follow-up. Discussion: Interventricular septal perforation during CSP is a possible complication during lead fixation. Pre-operative septal assessment with imaging can be helpful to provide important septal anatomical features. Septal perforation can be managed appropriately with lead repositioning intra-procedurally and close follow-up.

RESUMEN

BACKGROUND: Untreated multivessel disease (MVD) in acute myocardial infarction (AMI) has been linked to a higher risk of recurrent ischemia and death within one year . Current guidelines recommend percutaneous coronary intervention (PCI) for significant non-infarct artery (-ies) (non-IRA) stenosis in hemodynamically stable AMI patients with MVD, either during or after successful primary PCI, within 45-days. However, deciding the timing of revascularization for non-IRA in cases of MVD is uncertain. METHODS: This meta-analysis was performed based on PRISMA guidelines after registering in PROSPERO (CRD42023472652). Databases were searched for relevant articles published before 10 November 2023. Pertinent data from the included studies were extracted and analyzed using RevMan v5.4. RESULTS: Out of 640 studies evaluated, there were 13 RCTs with 5144 patients with AMI with MVD. The immediate non-IRA PCI is associated with a significantly lower occurrence of unplanned ischemia-driven PCI (OR 0.60; confidence interval [CI] 0.44-0.83) and target-vessel revascularization (OR 0.72; CI 0.53-0.97) . Although there is a favorable trend for major adverse cardiovascular and cerebrovascular events (MACCE), nonfatal AMI, cerebrovascular events, and major bleeding in the immediate non-culprit artery (-ies) PCI, those were statistically non-significant. Similarly, all-cause mortality, cardiovascular mortality, stent thrombosis, and acute renal insufficiency did not show significant differences between two groups. CONCLUSION: Among hemodynamically stable patients with multivessel AMI, the immediate PCI strategy was superior to the multistage PCI strategy for the unplanned ischemia-driven PCI and target-vessel revascularization while odds are favorable in terms of MACCE, nonfatal AMI, cerebrovascular events, and major bleeding at longest follow-up.

RESUMEN

BACKGROUND: Transcatheter Aortic Valve Replacement (TAVR) is the treatment of choice in patients with severe aortic stenosis. Transcarotid (TCa) or Trans-axillary/subclavian (TAx/Sc) are safer and less invasive non-femoral approaches, where transfemoral access is difficult or impossible to obtain. METHODS: This meta-analysis was performed based on PRISMA guidelines after registering in PROSPERO (CRD42023482842). This meta-analysis was performed to compare the safety of the transcarotid and trans-axillary/subclavian approach for TAVR including studies from inception to October 2023. RESULTS: Seven studies with a total of 6227 patients were included in the analysis (TCa: 2566; TAx/Sc: 3661). Transcarotid TAVR approach had a favorable trend for composite of stroke and all-cause mortality (OR 0.79, CI 0.60-1.04), all-cause mortality, stroke, major vascular complication, and new requirement of permanent pacemaker though those were statistically insignificant. On sub-analysis of the results of the studies based on the territory (USA vs French), composite outcome of all cause mortality, stroke and major bleeding (OR 0.54, CI 0.54-0.81), composite of stroke and all cause mortality (OR 0.64, CI 0.50-0.81), and stroke/TIA (OR 0.53, CI 0.39-0.73) showed lower odds of occurrence among patient managed with TCa approach in the American cohort. CONCLUSION: Overall, transcarotid approach had favorable though statistically insignificant odds for composite (stroke and all-cause mortality) and individual outcomes (stroke, all-cause mortality, etc.). There are significant variations in observed outcomes based on study's geographic location. Large prospective randomized clinical trials comparing the two approaches with representative samples are necessary to guide the clinicians in choosing among these approaches.

RESUMEN

Background and Aims: Despite the decriminalization of abortion in Nepal in 2002, unsafe abortion is still a significant contributor to maternal morbidity and mortality. Nepal has witnessed a significant drop in abortion-related severe complications and maternal deaths owing to the legalization of abortion laws, lowered financial costs, and wider accessibility of safe abortion services (SAS). However, various factors such as sociocultural beliefs, financial constraints, geographical difficulties, and stigma act as barriers to the liberal accessibility of SAS. This review aimed to determine key barriers obstructing women's access to lawful, safe abortion care and identify facilitators that have improved access to and quality of abortion services. Methods: A systematic search strategy utilizing the databases PubMed, CINAHL, Scopus, and Embase was used to include studies on the accessibility and safety of abortion services in Nepal. Data were extracted from included studies through close reading. Barriers and facilitators were then categorized into various themes and analyzed. Results: Of 223 studies, 112 were duplicates, 73 did not meet the inclusion criteria, and 18 did not align with the research question; thus, 20 studies were included in the review. Various barriers to SAS in Nepal were categorized as economic, geographic, societal, legal/policy, socio-cultural, health systems, and other factors. Facilitators improving access were categorized as economic/geographic/societal, legal/policy, socio-cultural, and health systems factors. The patterns and trends of barriers and facilitators were analyzed, grouping them under legal/policy, socio-cultural, geographic/accessibility, and health systems factors. Conclusion: The review identifies financial constraints, unfavorable geography, lack of infrastructure, and social stigmatization as major barriers to SAS. Economics and geography, legalization, improved access, reduced cost and active involvement of auxiliary nurse-midwives and community health volunteers are key facilitators.

RESUMEN

ABSTRACT: Sepsis and septic shock are life-threatening conditions that are associated with high mortality and considerable health care costs. The association between prior angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARBs) use and outcomes after sepsis is elusive. The aim of this study was to evaluate the role of the prior use of ACEi or ARBs and outcomes after sepsis and septic shock. A relevant literature review was performed in 4 databases from inception until July 2022. Independent reviewers first screened the title, abstract, and full text, and then, data extraction and analysis were performed. One post hoc analysis of a trial and 6 retrospective cohort studies were included in this review. There were 22% lower odds of in-hospital/30-day mortality among patients who have used ACEi/ARBs in the past [23.83% vs. 37.20%; odds ratio (OR), 0.78, 95% confidence interval (CI), 0.64-0.96], and reduced 90-day mortality (OR, 0.80, 95% CI, 0.69-0.92). ACEi/ARBs users were found to have 31% lesser odds of developing acute kidney injury as compared with nonusers (OR, 0.69, 95% CI, 0.63-0.76). There was no significant difference in the length of hospital stay (MD 1.26, 95% CI, ‒7.89 to 10.42), need for renal replacement therapy (OR, 0.71, 95% CI, 0.13-3.92), mechanical ventilation (OR, 1.10, 95% CI, 0.88-1.37) or use of vasopressors (OR, 1.21, 95% CI, 0.91-1.61). Based on this analysis, prior use of ACEi/ARBs lowers the risk of mortality and adverse renal events in patients with sepsis and septic shock.

RESUMEN

BACKGROUND: Takotsubo syndrome (TS) during pregnancy and postpartum is rare but may lead to significant maternal and fetal morbidity. We compared clinical characteristics and prognosis according to [a] timing of presentation (pregnancy vs post-partum) and [b] modes of delivery (cesarean section vs vaginal delivery). METHODS: Systematic review of articles published in PubMed, Scopus, Embase, and Medline databases from inception to July 30, 2023. Patient demographics, obstetric, electrocardiographic, laboratory, echocardiographic characteristics, and prognosis were summarized descriptively. RESULTS: An initial database search identified 2162 articles, of which 81 studies were included in this review. TS during pregnancy can have emotional, obstetric, and metabolic triggers and has a higher proportion of adverse fetal outcomes when compared with women who developed TS postpartum. Women with TS after cesarean section had an earlier onset and higher proportion of anesthesia use when compared with those who developed TS after vaginal delivery. There were no differences regarding the degree of systolic dysfunction or the need for advanced therapies, including ventilator support, intra-aortic balloon pump, and extracorporeal membrane oxygenation among groups. CONCLUSIONS: TS is associated with various triggers and adverse fetal outcomes when it develops during pregnancy than in the postpartum period. TS occurs more rapidly and with a more aggressive course after cesarean section than after vaginal delivery.

RESUMEN

PURPOSE: Cardiovascular adverse events (CVAEs) are common adverse effects of first-generation Bruton tyrosine kinase inhibitors (BTKis) and limit their use considerably. This led to the development of second-generation BTKis-acalabrutinib and zanubrutinib-which are more selective, potent, and presumed to have better safety profiles than the previous group of medications. However, there have been sporadic reports of CVAEs associated with second-generation BTKis in clinical practice. To address this issue, a comprehensive meta-analysis to pool the documented CVAEs was performed, including major hemorrhage, any bleeding, atrioventricular block, atrial fibrillation/flutter, pericardial effusion, pericarditis, heart failure, cardiac arrest, myocardial infarction, hypertension, hypotension, and stroke. This meta-analysis incorporated 8 studies. Among these, 6 were Phase III trials and 2 were Phase II trials. These studies collectively enrolled a total of 2938 patients. METHODS: Multiple databases, including PubMed, MEDLINE, Cochrane Library, Scopus, and EMBASE, were systematically searched for relevant clinical trials from inception through January 14, 2023. The effect measure used was odds ratio (OR) and 95% CI. FINDINGS: Of a total of 1774 studies identified during the initial database search, 8 were included in the meta-analysis. The incidence of overall and cardiovascular mortality was comparable between the 2 groups. There were no significant differences observed for cardiovascular mortality (OR = 0.36; 95% CI, 0.08-1.65; n = 2588; I2 = 45%; P = 0.19). Similar results were found for all-cause mortality (OR = 0.85; 95% CI, 0.67-1.07), any bleeding (OR = 1.90; 95% CI, 0.88-4.09), major bleeding (OR = 1.07; 95% CI, 0.65-1.76), atrioventricular block (OR = 0.74; 95% CI, 0.15-3.68), atrial fibrillation/flutter (OR = 0.74; 95% CI, 0.37-1.50), and other CVAEs associated with second-generation BTKis. IMPLICATIONS: Based on the available evidence, there is no indication of worse cardiovascular outcomes or superiority of second-generation BTKis compared with standard treatments in terms of safety profile. However, additional large-scale controlled trials are needed to provide robust support for the superior tolerability of new-generation BTKis.

RESUMEN

Background and Aims: Current clinical guidelines for treating left ventricular thrombus (LVT) are limited by inadequate evidence to inform the comparative efficacy of oral anticoagulants. In this meta-analysis, we aimed to compare the efficacy and safety of direct oral anticoagulants (DOAC) to vitamin K antagonists (VKA) in patients with LVT. Methods: Four standard databases were searched for relevant literature comparing the efficacy and safety between DOAC and VKA for LVT treatment, published before August 19, 2023. Both the randomized controlled trials and observational studies were included in the analysis. The outcomes of interest were the resolution of LVT, all-cause mortality, stroke, systemic embolism, and bleeding. Data from the selected studies were extracted and analyzed using RevMan 5.4 using odds ratio. Results: Among 3959 studies from the database search and bibliography review, 33 were included in the analysis. LVT resolution was observed in 72.59% in the DOAC group versus 67.49% in the VKA group (odds ratio [OR]: 1.28, confidence interval [CI]: 1.07-1.53). Mortality was lower in the DOAC group (11.71% vs. 18.56%) (OR: 0.60, CI: 0.36-1.00; borderline statistical significance). Likewise, bleeding events (9.60% vs. 13.19%) (OR: 0.65, CI: 0.52-0.81) and stroke (7.54% vs. 11.04%) (OR: 0.71, CI: 0.53-0.96) were also significantly lower in the DOAC group. Conclusion: DOAC use for LVT showed better thrombus resolution and reduced risk of bleeding and stroke compared to VKA. Likewise, DOAC use was associated with lower mortality with borderline statistical significance.

RESUMEN

Background: COVID-19 commonly affects the lungs and may lead to mild to severe hypoxemia. The supplemental oxygen requirement gradually reduces with the improvement in lung pathology. However, a few patients may have exertional desaturation, and ongoing oxygen needs at the time of hospital discharge. The objective of this research was to study the requirement of oxygen therapy in the immediate post-COVID-19 period and its associated risk factors. Materials and Methods: An analytical cross-sectional study was conducted on the admitted post-COVID-19 patients who had recently tested real-time polymerase chain reaction (RT-PCR) negative in a tertiary care center from August 2021 to mid of October 2021. Nonprobability consecutive sampling was used, and the sample size was 108. The data were analyzed using the Statistical Package for the Social Sciences (IBM-SPSS), version 23. The mode of oxygen therapy (nasal cannula, face mask, reservoir mask, or mechanical ventilation) in the first two weeks of the study was presented appropriately in a table. The nonparametric statistical tests were applied to determine the association between the duration of post-COVID-19 oxygen therapy and several other risk factors such as age, gender, comorbidities, smoking status, exposure to firewood, COVID-19 vaccination, and severity of COVID-19. Results: 95 (87.96%) cases required oxygen therapy in their immediate post-COVID-19 period. The overall median duration of oxygen therapy was 6.00 (4.00-10.00) days. The nasal cannula was the most commonly used mode of oxygen supplement. The duration of oxygen therapy was significantly higher in patients aged more than 60 years (6.00 [5.00-11.00], p = 0.013), chronic obstructive pulmonary disease (10.00 [6.00-12.75], p = 0.006), history of chronic smoking (9.00 [5.50-13.00], p = 0.044), and severe COVID-19 infection (7.00 [5.00-10.50], p = 0.042). Conclusions: The proportion of patients requiring oxygen therapy in the immediate post-COVID-19 period was higher than that reported in other studies. In addition, old age (>60 years), chronic obstructive pulmonary disease, chronic smoking, and severe COVID-19 infection significantly increased the duration of oxygen therapy. So, these factors should be assessed while discharging patients from COVID-19 facilities, and oxygen supplementation should be planned for needy patients.

RESUMEN

BACKGROUND: The use of bivalirudin-based anticoagulation over heparin-based anticoagulation for coronary percutaneous intervention has been debated for a long time. Multiple trials have shown promising benefits of bivalirudin over heparin therapy with the most recent addition being the BRIGHT-4 trial. We performed a meta-analysis to assess evidence from these trials, focusing on the coronary intervention of the STEMI population. METHODS: This meta-analysis was performed based on PRISMA guidelines after registering in PROSPERO (CRD42023394701). Databases were searched for relevant articles published before January 2023. Pertinent data from the included studies were extracted and analyzed using RevMan v5.4. RESULTS: Out of 2375 studies evaluated, 13 randomized control trials with 24 360 acute ST-elevation myocardial infarction patients were included for analysis. The bivalirudin-based anticoagulation reduced the net clinical events (OR 0.75, CI 0.61-0.92), major adverse cardiac or cerebral events (OR 0.85, CI 0.74-0.98), any bleeding (OR 0.61, CI 0.45-0.83), major bleeding (OR 0.54, CI 0.39-0.75), all-cause mortality (OR 0.79, CI 0.67-0.92) and cardiac mortality (OR 0.78, CI 0.65-0.93) significantly without increasing the risk of any stent thrombosis (OR 0.92, 95% CI 0.52-1.61), definite stent thrombosis (OR 1.17, 95% CI 0.62-2.22) and acute stent thrombosis (OR 2.06, 95% CI 0.69-6.09) significantly at 30 days. CONCLUSION: Based on this meta-analysis, bivalirudin plus a post-PCI high-dose infusion-based anticoagulation during STEMI PCI has significant benefits over heparin therapy for cardiovascular outcomes without a significant increase in the risk of thrombotic outcomes.

RESUMEN

BACKGROUND: Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation of atrial fibrillation (AF); however, the results are suboptimal for persistent AF. The left atrial posterior wall (LAPW) is thought to be a major additional area in initiation and perpetuation of persistent AF. Therefore, adjunctive ablation of the posterior wall may reduce AF recurrence in patients with persistent AF. OBJECTIVE: The objective of this study was to compare outcomes of catheter ablation in patients with persistent AF using PVI alone versus a combination of PVI and LAPW isolation. METHODS: Literature search was conducted in PubMed, PubMed Central, Scopus, and Embase since inception to February 2023. Screening of studies was done via Covidence software. Risk of bias assessment was done using appropriate tools. Data extraction and a narrative synthesis were carried out accordingly. RESULTS: Ten studies were included, of which five were randomized controlled trials. PVI with LAPW ablation group had significantly lower recurrence of overall atrial tachyarrhythmia (OR 0.47, CI 0.32-0.70) and AF (OR 0.39, CI 0.23-0.69). In sensitivity analysis, freedom from atrial arrhythmias was noted to be significantly higher in the PVI with LAPW ablation group (OR 2.22, CI 1.36-3.64). However, there was no significant difference in occurrence of atrial flutter (OR 1.36, CI 0.86-2.14) or with periprocedural adverse events (OR 1.10, CI 0.60-1.99). CONCLUSION: LAPW ablation, in addition to PVI, significantly improves the rates of arrhythmia freedom and reduces the recurrence of overall atrial tachyarrhythmia. There was no significant difference in atrial flutter or periprocedural adverse events.

RESUMEN

Hairy cell leukemia (HCL) represents a rare B-cell malignancy with 2% of all leukemias and should be differentiated from HCL-like conditions, including HCL-variant (HCL-V) and splenic diffuse red pulp lymphoma (SDRPL). HCL gets its name from the short, thin projections that look like hair on its cells. It is associated with a specific immunophenotypic profile, cytopenia, and splenomegaly. Spontaneous splenic rupture can be a symptom of hematological malignancy such as HCL and is a life-threatening acute emergency. Here, we present a case of a 37-year-old man who presented to the hospital with signs of acute peritonitis and acute anemia and was found to have atraumatic splenic rupture secondary to splenomegaly. He underwent emergent angiography, where the bleeding splenic vessel was identified, and the patient was successfully treated with embolization. Immunophenotypic profile revealed that B-cells were positive for CD11c, CD103, CD25, and CD5, for which he received five days of cladribine and achieved complete clinical remission.

RESUMEN

Background and Aims: Hepatitis B is a leading cause of chronic liver disease and subsequent liver transplantation. This is a vaccine-preventable illness. Health workers continue to be at risk for blood-borne pathogens due to occupational exposures. The overall goals of our study were to determine the prevalence of exposure to needle sticks and sharp-related injuries (NSSI) and hepatitis B vaccination status among healthcare workers (HCWs) of Nepalgunj Medical College Teaching Hospital (NGMCTH), Kohalpur, Banke, Nepal. Methods: A descriptive cross-sectional study was conducted among HCWs at the NGMCTH following ethics approval by the NGMCTH Ethics Review Committee. A pretested structured questionnaire was used to compile the data. Data was collected from September 15, 2021 to September 14, 2022. Collected data entered in Microsoft Excel and analyzed using statistical package for social sciences version 22. Analyzed data were presented using simple descriptive statistics with appropriate figures and tables. Results: A total of 304 among 506 HCWs (60.1%) participated in the survey were exposed to Needle sticks. Nine of whom (3.7%) were injured substantially (more than 10 times). Among nursing students, 21.3% had experience with NSSI. 71.7% of HCWs had received at least one dose of the hepatitis B vaccine, of whom 61.9% (44.5% of total HCWs) had received three doses. Conclusions: This study demonstrated that more than two-quarters of HCWs were exposed to NSSI. Despite being at risk, vaccination status was still low, and less than half only received three complete doses. Precaution should be taken when working with instrumentation and procedures. Hepatitis B immunization programs for HCWs should be delivered at no cost with 100% coverage and protection. Raising awareness about hepatitis B infection and immunization remains crucial to primary prevention.

RESUMEN

Background and Aims: Cerebral embolic protection (CEP) devices are employed to capture embolic debris and reduce the risk of stroke during transcatheter aortic valve replacement (TAVR). Evidence is mixed regarding the safety and efficacy of CEP. We aimed to summarize the safety and effectiveness of CEP use during TAVR. Methods: Electronic databases, including PubMed, PubMed Central, Scopus, Cochrane Library, and Embase, were searched using relevant search terms for articles relating to CEP. All relevant data from 20 studies were extracted into a standardized form. Statistical analyses were performed using Revman 5.4. Odds ratio (OR) or mean differences (MDs) were used to estimate the desired outcome with a 95% confidence interval (CI). Results: Twenty studies (eight randomized controlled trials [RCTs]) involving 210,871 patients (19,261 in the CEP group and 191,610 in TAVR without the CEP group) were included. The use of CEP was associated with a lower odds of 30-day mortality by 39% (OR: 0.61, 95% CI: 0.53-0.70) and stroke by 31% (OR: 0.69, 95% CI: 0.52-0.92). Comparing devices, benefit in terms of mortality and stroke was observed with the use of the Sentinel device (Boston Scientific), but not among other devices. No differences were observed in the outcomes of acute kidney injury, major or life-threatening bleeding events, or major vascular complications between groups. When only RCTs were included, there were no observed differences in the primary or secondary outcomes for CEP versus no CEP use during TAVR. Conclusions: The totality of evidence suggests a net benefit for the use of CEP, weighted by studies in which the Sentinal device was used. However, given the RCT subanalysis, additional evidence is needed to identify patients at the highest risk of stroke for optimal decision-making.

RESUMEN

Protein C (PC) is an essential vitamin K-dependent protein that regulates thrombosis and hemostasis in the body. A mutation in the PROC gene on chromosome 2q14.3 results in PC deficiency. The clinical presentation of PC deficiency can vary, ranging from a single vein thrombosis to disseminated intravascular coagulation, purpura fulminans, or even life-threatening complications such as sepsis. Here, we present a case of a 37-year-old female who was found to have acute portal vein thrombosis as an initial presentation of PC deficiency. She presented to the hospital with acute onset of abdominal pain associated with nausea, blood-streaked emesis, and bloody bowel movement.

RESUMEN

Both the right-sided aortic arch with mirror-image branching (RAMI) and the congenital absence of the left pulmonary artery are sporadic congenital defects. Both diseases are typically diagnosed in childhood, but occasionally asymptomatic cases may be incidentally detected through imaging in adulthood. We reported a 43-year-old female patient with a RAMI and congenital absence of the left pulmonary artery who was relatively asymptomatic until adulthood.
