Efficacy and safety of over-the-scope-clips in the therapy of acute nonvariceal upper gastrointestinal bleeding: Meta-analysis.

Acute nonvariceal upper gastrointestinal bleeding (ANVUGIB) is a frequent life-threatening acute condition in gastroenterology associated with high morbidity and mortality. Over-the-scope-clip (OTSC) is a new endoscopic hemostasis technique, which is being used in ANVUGIB and is more effective. To summarize and analyze the effects of the OTSC in prevention of recurrent bleeding, clinical success rate, procedure time, hospital stay, and adverse events in the treatment of ANVUGIB, to evaluate whether OTSC can replace standard endoscopic therapy as a new generation of treatment for ANVUGIB. The literature related to OTSC and standard therapy for ANVUGIB published before January 2023 was searched in PubMed, Web of Science, EMBASE, Cochrane, Google, and CNKI databases. Changes in recurrent bleeding (7 or 30 days), clinical results (clinical success rate, conversion rate to surgery, mortality), therapy time (procedure time, hospital stay), and adverse events in the OTSC intervention group were summarized and analyzed, and the MD or OR of 95%CI is calculated by Review Manager 5.3. This meta-analysis involved 11 studies with 1266 patients. Total risk of bias was moderate-to-high. For patients in the OTSC group, 7- and 30-days recurrent bleeding rates, as well as procedure time, hospital stay, and intensive care unit stay, were greatly inhibited. OTSC could significantly improve the clinical success rate of ANVUGIB. OTSC therapy did not cause serious adverse and was effective in reducing patient mortality. OTSC may provide more rapid and sustained hemostasis, and thus, promote recovery and reduce mortality in patients with ANVUGIB. In addition, the safety of OTSC is assured.

Association of ACE2 and TMPRSS2 towards COVID-19 susceptibility

Severe Acute Respiratory Syndrome-Corona Virus-2 (SARS-CoV-2) is pneumonia like viral disease which was originated from Wuhan China in 2019. Besides its high morbidity and mortality, a lot of physiological, enzymatic, hormonal and genetic imbalances had also been observed among Corona Virus Disease-19 (COVID-19) patients. The purpose of the present study was the assessment of comorbidities and association of single nucleotide polymorphisms (SNPs) in Angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine (TMPRSS) gene among COVID-19 patients. A total of 300 (healthy control n = 150 COVID-19 n = 150) individuals were sampled and genotyped for ACE2 rs2285666 and TMPRSS rs2070788 SNPs respectively. A total of 92/150 (61.3%) were male infected population, among the various age groups (age group 1: 1–15 yrs; age group 2: 16–30 yrs; age group 3: 31–45; age group 4: 46 and above) where most of the patients were from age group 4 (46 and above) 79/150 (52.7%) followed by age group 3 (31–45) 44/150 (29.3%). Logistic regression analysis showed that among clinical features cough (90%) was observed to be highest followed by fever (80%), sore throat (76%) and shortness of breath (75%). Hypertension (51%), type II diabetes (48.4%), ischemic heart disease (43.3%) history was found to prevalent highly associated with infected individuals. For ACE2 rs2285666, we found disease risk association for both allele and genotype while TMPRSS did not reveal genotype association. It is concluded from the current study that COVID-19 infects majority of male population. ACE2 rs2285666 allele and genotype association was observed with COVID-19 infection and protective association of TMPRSS2 rs2070788 allele towards COVID-19 infection.

Comparative analysis of leukemia and risk estimation in working age population between provinces of Ecuador.

Leukemia is associated with exposure to radiation, benzene derivatives, and pesticides. Previous research has documented an increase in work-related leukemia in the Latin American Andean region. To date, there are only few studies in Ecuador on the impact of oil exploitation on adjacent indigenous communities. Our study aims to show the impact of leukemia on the working-age population. For the calculation of morbidity and mortality rates, we used hospital discharge and death records from the National Institute of Statistics of Ecuador. These data were collected and adjusted to the corresponding province's population for further analysis. Large differences were observed between provinces in adjusted rates of leukemia mortality and morbidity in the working-age population. The variations in altitude among different areas in Ecuador give the provinces a distinct geographic identity. Likewise, the provinces with the highest morbidity and mortality rankings, such as Azuay, Loja, Imbabura, and Tungurahua, have an average altitude above 2000 meters. As a result, there are variations in the average temperature, exposure to solar and cosmic radiation, and mining and farming methods. The observed differences warrant the future collection of geolocation data for affected individuals. This could help to better understand how leukemia cases have demogrpahic hotspots in the country, identify possible risk factors associated with the disease in each region, and design more effective prevention and control strategies.

Is Prompt Hyperbaric Oxygen Adjunctive Therapy Able to Reduce Mortality and Amputation in Management of Necrotizing Soft-Tissue Infection?

Background: Necrotizing soft-tissue infection (NSTI) is a rare and serious disease with high morbidity and mortality. Standard therapeutic concepts have included urgent surgical intervention, broad-spectrum antibiotic treatment, and intensive care. Hyperbaric oxygen therapy (HBOT) is used as adjuvant therapy in some centers, but its benefits remain controversial. Methods: A retrospective analysis was conducted in which 98 patients with a clinical diagnosis of NSTI were treated with standard treatments plus HBOT. The clinical outcomes were wound healing, performance status, hospital length, complication rate, recurrence rate, morbidity (amputation rate), and mortality. Primary or secondary outcomes were compared between the time interval of HBOT and the clinical outcomes. Results: The average times from diagnosis of NSTI to initial HBO treatment and from initial surgery to initial HBO treatment were both significantly longer in dead patients than in surviving patients (P = 0.031; P = 0.020). These two time intervals were both significantly longer in amputated patients than in preserved patients (P = 0.031; P = 0.037). Conclusions: Using combined treatment with early surgical debridement combined with HBOT, it is possible to reduce hospital stay, intensive care unit stay, number of debridements, improve complete wound healing rate, and lower amputation and mortality rates among patients with NSTI. The early onset of HBOT soon after diagnosis, especially during critical conditions, is proved to be associated with higher survival and preservation rates.

Evaluation of effectiveness, viability and potential of molecular techniques as a research tool of Salmonella spp. in eggs

The majority of food intoxication is caused by Salmonella spp. originating from the intake of contaminated food, particularly of poultry and eggs. It is one of the most important zoonoses for Public Health, to be difficult to control, due to its high endemicity and morbidity and cause great socioeconomic impacts. This study aimed to investigate and identify the presence of Salmonella spp. in eggs and to verify the effectiveness of the Polymerase Chain Reaction (PCR) as a test for the diagnosis of Salmonella spp. For this, eggs commercialized in the city of Patos-PB were used. It was identified that the isolates have genes encoding virulence factors (spvC e invA), important indicators of pathogenicity and high risk to the consumer. Despite the high specificity, PCR showed high complexity in the identification of the colonies compared to conventional biochemical techniques, however, it was found that the use of more than one identification method contributes favorably, by increasing the probability of detection of Salmonella spp. Nevertheless, it is imperative more researchs of the identification of Salmonella spp., in order to standardize PCR techniques, with the purpose of making it more efficient and viable for microbiological control in the food industry.

Identification of key genes associated with cervical cancer based on bioinformatics analysis

BackgroundCervical cancer has extremely high morbidity and mortality, and its pathogenesis is still in the exploratory stage. This study aimed to screen and identify differentially expressed genes (DEGs) related to cervical cancer through bioinformatics analysis.MethodsGSE63514 and GSE67522 were selected from the GEO database to screen DEGs. Then GO and KEGG analysis were performed on DEGs. PPI network of DEGs was constructed through STRING website, and the hub genes were found through 12 algorithms of Cytoscape software. Meanwhile, GSE30656 was selected from the GEO database to screen DEMs. Target genes of DEMs were screened through TagetScan, miRTarBase and miRDB. Next, the hub genes screened from DEGs were merged with the target genes screened from DEMs. Finally, ROC curve and nomogram analysis were performed to assess the predictive capabilities of the hub genes. The expression of these hub genes were verified through TCGA, GEPIA, qRT-PCR, and immunohistochemistry.ResultsSix hub genes, TOP2A, AURKA, CCNA2, IVL, KRT1, and IGFBP5, were mined through the protein-protein interaction network. The expression of these hub genes were verified through TCGA, GEPIA, qRT-PCR, and immunohistochemistry, and it was found that TOP2A, AURKA as well as CCNA2 were overexpressed and IGFBP5 was low expression in cervical cancer.ConclusionsThis study showed that TOP2A, AURKA, CCNA2 and IGFBP5 screened through bioinformatics analysis were significantly differentially expressed in cervical cancer samples compared with normal samples, which might be biomarkers of cervical cancer.

Impact of sodium-glucose cotransporter-2 inhibitor use on peak VO2 in advanced heart failure patients.

Advanced heart failure (HF) is an epidemic that affects multiple organ systems with high morbidity and mortality rates despite optimal medical therapy (OMT) and remains the leading cause of hospitalizations in type 2 diabetes-related cardiovascular disease. The addition of sodium-glucose co-transporter inhibitors (SGLT2i) in treating these patients has seen improved mortality and hospital admission rates. As such, we felt it was important to investigate whether the use of SGLT2i improved functional capacity in patients with HF when compared to OMT by evaluating maximum oxygen consumption (peak VO2) using cardiopulmonary exercise testing (CPET). We found 94 heart failure patients between August 2020 and August 2021 who underwent CPET before and after treatment at Mayo Clinic in Florida. 50 patients received OMT and 44 received OMT and SGLT2i therapy. CPET results before and after were compared for each group. The baseline ejection fraction was not significantly different between groups, with the OMT group at 38% and the SGLT2i group at 33%, p = 0.10. OMT patients were found to have a significantly lower hemoglobin A1c of 5.7 (5.4-6.1) compared to those with SGLT2i therapy of 6.4 (5.8-7.1), p = 0.01. The baseline peak VO2 was 17.3 ml/kg/min (13.3-21.6) in the OMT group and 17.3 ml/kg/min (14.4-18.9) in the SGLT2i group, p = 0.18, not significantly different. The interesting finding is that the follow-up peak VO2 at one year for the OMT group was 17 ml/kg/min (13.3-21.6), which was not significantly different from the SGLT2i group peak VO2 of 17 ml/kg/min (14.6-19.6), p = 0.19. Our study is the first to compare before and after peak VO2 values of the OMT+SGLT2i group to the patient's own baseline and we found no significant improvement. Our single-center data shows no improvement in functional capacity after the addition of SGLT2i therapy to OMT in patients with advanced heart failure. Improved hospitalization and symptoms may be attributed to other numerous effects of SGLT2i such as volume management.

Validation of Educational Materials for a Mobile Application for Patients with Kidney Disease on Hemodialysis.

Worldwide, chronic kidney disease (CKD) is a public health problem due to its high morbidity and mortality rates. For CKD patients, mobile health applications have functioned as a strategy that promotes patient care through valid and reliable educational materials. This is a prospective and descriptive three-stage study using content experts. Results created three visual and three audiovisual materials with acceptable evaluations. The design and validation of educational materials are a valid and reliable method for patient health education through mobile health applications.

Aspiration pneumonia in nursing literature-a mapping review.

Aspiration pneumonia (AP) is an infection of the lungs caused by inhalation of material. The reported incidences vary across literature and clinical populations and is associated with high morbidity and mortality. Management of AP is best carried out by a multidisciplinary team. This aim of this review was to collate and describe the available evidence on AP to develop a greater understanding of the concept of AP as it is represented in the nursing literature. As a collaborative team, we undertook the six stages of a systematic mapping review. We searched for the term aspiration pneumonia in 200 peer reviewed nursing journals across 10 databases, over a ten-year period (2013-2023). In this review, 293 papers were coded. Dysphagia, oral health and tube feeding emerged as the most frequent risk factors for AP, and the most reported factors for preventing this condition. Mortality was the most commonly described consequence of AP, followed by hospitalisations and morbidity. Multiple management approaches were reported including dysphagia assessment, risk evaluation, oral care and texture modification of food and fluids. The role of nurses and interprofessional collaborations were described. Despite limited evidence related to the topic of AP in the nursing literature, the complexity of the causes, prevention, management and consequences of AP emerged. Certain factors, such as dysphagia, oral health, and tube feeding, were described under prevention, cause and management of AP. The importance of multidisciplinary approach in the management and prevention of AP was presented.

Discovery of anti-Mycobacterium tuberculosis desertomycins from Streptomyces flavofungini TRM90047 based on genome mining and HSQC-TOCSY

Tuberculosis caused by Mycobacterium tuberculosis (M. tb) is a major public health problem with high morbidity and mortality worldwide. In our previous study, we found that a fermentation product of Streptomyces flavofungini TRM90047 exhibited anti-M. tb activity and decreased the expression level of several genes, including rpsL, Rplc and ClpC1. Guided by heteronuclear single quantum correlation-total correlation spectroscopy (HSQC-TOCSY) fingerprints and genome mining, we isolated two new 44-membered macrolides, desertomycin 44-1 (1) and desertomycin 44-2 (2), together with known desertomycin A (3) from S. flavofungini TRM90047. Three desertomycins showed anti-M. tb activity. The EC50 values of desertomycin A, desertomycin 44-1 and desertomycin 44-2 were 25 µg/mL, 25 µg/mL and 50 µg/mL, respectively. Molecular docking analyses revealed that the isolated desertomycins bound well to the RPSL, RPLC and CLPC1 proteins. In the present study, we describe the discovery of new anti-M. tb compounds guided by genome mining, HSQC-TOCSY and anti-M. tb bioassays.

Beyond the debut: unpacking six years of Hypotension Prediction Index software in intraoperative hypotension prevention - a systematic review and meta-analysis.

Intraoperative hypotension (IOH) during general anesthesia is associated with higher morbidity and mortality, although randomized trials have not established a causal relation. Historically, our approach to IOH has been reactive. The Hypotension Prediction Index (HPI) is a machine learning software that predicts hypotension minutes in advance. This systematic review and meta-analysis explores whether using HPI alongside a personalized treatment protocol decreases intraoperative hypotension. A systematic search was performed in Pubmed and Scopus to retrieve articles published from January 2018 to February 2024 regarding the impact of the HPI software on reducing IOH in adult patients undergoing non-cardio/thoracic surgery. Excluded were case series, case reports, meta-analyses, systematic reviews, and studies using non-invasive arterial waveform analysis. The risk of bias was assessed by the Cochrane risk-of-bias tool (RoB 2) and the Risk Of Bias In Non-randomised Studies (ROBINS-I). A meta-analysis was undertaken solely for outcomes where sufficient data were available from the included studies. 9 RCTs and 5 cohort studies were retrieved. The overall median differences between the HPI-guided and the control groups were - 0.21 (95% CI:-0.33, -0.09) - p < 0.001 for the Time-Weighted Average (TWA) of Mean Arterial Pressure (MAP) < 65mmHg, -3.71 (95% CI= -6.67, -0.74)-p = 0.014 for the incidence of hypotensive episodes per patient, and - 10.11 (95% CI= -15.82, -4.40)-p = 0.001 for the duration of hypotension. Notably a large amount of heterogeneity was detected among the studies. While the combination of HPI software with personalized treatment protocols may prevent intraoperative hypotension (IOH), the large heterogeneity among the studies and the lack of reliable data on its clinical significance necessitate further investigation.

Role of endothelial glycocalyx in central nervous system diseases and evaluation of the targeted therapeutic strategies for its protection: a review of clinical and experimental data.

Central nervous system (CNS) diseases, such as stroke, traumatic brain injury, dementia, and demyelinating diseases, are generally characterized by high morbidity and mortality, which impose a heavy economic burden on patients and their caregivers throughout their lives as well as on public health. The occurrence and development of CNS diseases are closely associated with a series of pathophysiological changes including inflammation, blood-brain barrier disruption, and abnormal coagulation. Endothelial glycocalyx (EG) plays a key role in these changes, making it a novel intervention target for CNS diseases. Herein, we review the current understanding of the role of EG in common CNS diseases, from the perspective of individual pathways/cytokines in pathophysiological and systematic processes. Furthermore, we emphasize the recent developments in therapeutic agents targeted toward protection or restoration of EG. Some of these treatments have yielded unexpected pharmacological results, as previously unknown mechanisms underlying the degradation and destruction of EG has been brought to light. Furthermore, the anti-inflammatory, anticoagulative, and antioxidation effects of EG and its protective role exerted via the blood-brain barrier have been recognized.

Epidemiological and Cardiovascular Prognostic Profile of Pediatric Arterial Hypertension at the Hospital National Ignace Deen de Conakry (Guinea)

&amp;lt;i&amp;gt;Introduction&amp;lt;/i&amp;gt;: The prevalence of hypertension in children is much lower, around 1 to 5%. Clinical signs are still marked by accidents revealing neurological, cardiac and renal damage. The aim was to determine the epidemiological profile and prognosis of pediatric hypertension at the Ignace Deen National Hospital. Materials and methods: This was a prospective descriptive study of children and adolescents admitted to the pediatric ward of the Ignace Deen National Hospital during the period March 1 to August 31, 2021. All those aged 1 to 15 years declared hypertensive with mean systolic or diastolic blood pressure ≥ 95th percentile were included in this study. &amp;lt;i&amp;gt;Results&amp;lt;/i&amp;gt;: Out of a total of 464 patients, our study included 12 cases, representing a 2.52% incidence of arterial hypertension; the mean age of our patients was 8 years ±2 years; males predominated, with a sex ratio equal to 2; physical signs were marked by edema of the lower limbs (66.67%); Immediately threatening hypertension represented 41.67%; hypertensive retinopathy was found in 33.33% of patients; 16.67% of patients presented with LVH; 25%; renal complications were 25%; mortality was of the same order 25%. &amp;lt;i&amp;gt;Conclusion&amp;lt;/i&amp;gt;: The complications of pediatric hypertension are a real public health problem, with a high morbidity and mortality rate.

"Lupus Doesn't Have Me, I Have Lupus": Using Patient-Centered Interviews to Understand Medication Nonadherence.

Lupus nephritis (LN) is the most common cause of kidney injury in systemic lupus erythematosus and associated with higher morbidity and mortality. Low medication adherence correlates with adverse clinical outcomes. In a large, integrated health system at Kaiser Permanente East Bay Area, the authors identified mycophenolate mofetil (MMF) prescriptions for LN and collected patient demographics, medication adherence, and copay data. They interviewed patients with low medication adherence rates to understand contributing factors, such as side effects, cost, refill processes, and laboratory draws. Adherence was defined as a proportion of days covered at > 80%. The proportion of days covered is the number of days covered by a medication divided by the number of days in a defined period. Between November 30, 2021, and November 30, 2022, the authors identified 36 patients with LN on MMF. Almost a third (11/36) of these patients were nonadherent to medication. More than half (7/11) of these patients agreed to be interviewed. They identified the following causes of medication nonadherence: forgetfulness (57%, or 4/7), incomplete laboratory work (28%, or 2/7), medication cost (14%, or 1/7), and intentionally missed doses (14%, or 1/7). No patients identified medication side effects as a cause. The median 30-day copay for MMF was $4.55, and 28% (2/7) of patients paid $0 for their medications. In the authors' integrated health system, 69% of their patients with LN on MMF were adherent to their medication regimen. Forgetfulness was a challenge for the nonadherent patients. Kaiser Permanente East Bay Area provides convenient refills and laboratory draws; this likely facilitates medication adherence.

Adnexal torsion: A comprehensive review of types, pathophysiology, diagnosis, and management strategies during pregnancy

Adnexal torsion is a gynecological surgical emergency which during pregnancy can be associated with high patient morbidity and fetal mortality if not managed promptly. Fertility preservation is an essential concern. The underlying pathophysiology involves ovarian tissue torsion on its pedicle, leading to decreased venous return, stromal edema, internal hemorrhage, and infarction. It can affect females of all age groups, and they present mainly with an acute onset of pelvic pain, followed by nausea and vomiting. Multiple risks can lead to adnexal torsion, including ovulation induction, use of in vitro fertilization, and the presence of an ovarian mass. Early diagnosis is challenging and mainly depends on clinical suspicion, ultrasound, or MRI findings; however, it is necessary to preserve the function of the ovaries and fallopian tubes and prevent the occurrence of infertility. Once adnexal torsion is suspected, surgery or detorsion is the main line of treatment. This review will summarize the most relevant studies on risk factors, radiological findings, and managing maternal adnexal torsion in pregnancy.

Nebulized milk exosomes loaded with siTGF-β1 ameliorate pulmonary fibrosis by inhibiting EMT pathway and enhancing collagen permeability

Pulmonary Fibrosis (PF) is a fatal disease in the interstitial lung associated with high mortality, morbidity, and poor prognosis. Transforming growth factor-β1 (TGF-β1) is a fibroblast-activating protein that promotes fibrous diseases. Herein, an inhalable system was first developed using milk exosomes (M-Exos) encapsulating siRNA against TGF-β1 (MsiTGF-β1), and their therapeutic potential for bleomycin (BLM)-induced PF was investigated. M-siTGF-β1 was introduced into the lungs of mice with PF through nebulization. The collagen penetration effect and lysosomal escape ability were verified in vitro. Inhaled MsiTGF-β1 notably alleviated inflammatory infiltration, attenuated extracellular matrix (ECM) deposition, and increased the survival rate of PF mice by 4.7-fold. M-siTGF-β1 protected lung tissue from BLM toxicity by efficiently delivering specific siRNA to the lungs, leading to TGF-β1 mRNA silencing and epithelial mesenchymal transition pathway inhibition. Therefore, M-siTGF-β1 offers a promising avenue for therapeutic intervention in fibrosis-related disorders.

The Epidemiology of Pediatric Thermal Injury-Associated Toxic Shock Syndrome: A Systematic Review.

Thermal injury-associated toxic shock syndrome (TSS) is a life-threatening condition that can occur in children following burn injuries. The objective of this study was to describe the clinical manifestations, treatment, and outcomes of children who experienced TSS following a thermal injury. Additionally, the existing literature was systematically examined, and published cases of pediatric TSS occurring after burns were compiled. In June 2023, without regard for time constraints, articles that met the criteria were searched across several electronic databases. The inclusion criteria were English-language publications, pediatric patients, and reported outcomes of interest for clinical questions. Due to the heterogeneity of the included publications and the lack of data in an appropriate format, a meta-analysis was not feasible. Our research identified 23 studies published between 1980 and 2023, including 72 cases (from multiple countries) that met the inclusion criteria. Of the 72 patients with thermal injuries complicated by TSS, 53 (73.6%) children survived, 6 (8.3%) died, and for 13 (18%) cases, the outcome was not documented. Our systematic review highlights the rarity, severity, and complexity of pediatric thermal injury-associated TSS. Key findings from the review indicate that pediatric thermal injury-associated TSS carries a high mortality rate and significant morbidity. By increasing awareness, improving diagnostic accuracy, and optimizing treatment strategies, healthcare professionals can improve patient outcomes in this challenging condition.

Gut microbiota in preterm infants with late-onset sepsis and pneumonia: a pilot case-control study

BackgroundLate-onset sepsis (LOS) and pneumonia are common infectious diseases, with high morbidity and mortality in neonates. This study aimed to investigate the differences in the gut microbiota among preterm infants with LOS, or pneumonia, and full-term infants. Furthermore, this study aimed to determine whether there is a correlation between intestinal pathogenic colonization and LOS.MethodsIn a single-center case‒control study, 16 S rRNA gene sequencing technology was used to compare gut microbiota characteristics and differences among the LOS group, pneumonia group, and control group.ResultsOur study revealed that the gut microbiota in the control group was more diverse than that in the LOS group and pneumonia group (P < 0.05). No significant differences in diversity were detected between the LOS and pneumonia groups (P > 0.05). Compared with the control group, the abundances of Akkermansia, Escherichia/Shigella, and Enterococcus increased, while the abundances of Bacteroides and Stenotrophomonas decreased in the LOS and pneumonia groups. The pathogenic bacteria in infants with LOS were consistent with the distribution of the main bacteria in the intestinal microbiota. An increase in Escherichia/Shigella abundance may predict a high risk of LOS occurrence, with an area under the curve (AUC) of 0.773.ConclusionChanges in the gut microbiota composition were associated with an increased risk of LOS and pneumonia. The dominant bacteria in the gut microbiota of the LOS group were found to be associated with the causative pathogen of LOS. Moreover, preterm infants exhibiting an elevated abundance of Escherichia/Shigella may be considered potential candidates for predicting the onset of LOS.

Risk Factors of Acute Ischemic Stroke and Mortality Among Adults With Endocardial Fibroelastosis.

Endocardial fibroelastosis (EFE) is a rare form of restrictive cardiomyopathy associated with high morbidity and mortality. The literature is sparse on information pertaining to risk stratification. Thus, we sought to highlight the risk factors of acute ischemic stroke (AIS) and mortality in adults with EFE. The National Inpatient Sample (NIS) database was queried from 2001 to 2020 using the International Classification of Diseases 9th Revision (ICD-9) and 10th Revision (ICD-10) codes for adult patients with EFE. Factors associated with AIS and mortality were identified. In all, 18495 cases of EFE fit the inclusion criteria, of which 2370 (12.82%) had AIS. The mean ages for patients with and without AIS were 62.37 and 54.24, respectively. Multivariate regression suggested greater odds of AIS in patients with hypertension (aOR 2.329, P<0.01), dyslipidemia (aOR: 1.566, P<0.01), peripheral vascular disease (PVD) (aOR: 1.736, P<0.01), alcohol abuse (aOR: 1.817, P<0.01), age >60y (aOR: 1.646, P<0.01), females (vs. males, aOR: 1.238, P<0.01), and smokers (aOR: 1.697, P<0.01). Patients with cirrhosis (aOR: 0.174, P<0.01), CKD (aOR: 0.369, P<0.01), COPD (aOR: 0.402, P<0.01), atrial fibrillation (aOR: 0.542, P<0.01) had lower odds of AIS. 3.1% of EFE patients with AIS died. Diabetes (aOR: 11.665, P<0.01) and COPD (aOR: 3.201, P=0.017) were associated with the greatest odds of all-cause mortality. Dyslipidemia (aOR: 0.387, P=0.010) and females (vs. males, aOR: 0.432, P=0.012) had reduced odds of all-cause mortality. Several risk factors are associated with AIS in EFE, while diabetes, COPD, and being male are associated with mortality in EFE.

Preclinical research progress in HER2-targeted small-molecule probes for breast cancer.

Breast cancer is amalignant tumor that has the highest morbidity and mortality in women worldwide. Human epidermal growth factor receptor2 (HER2) is akey driver of breast cancer development. Therefore, accurate assessment of HER2 expression in cancer patients and timely initiation or termination of anti-HER2 treatment are crucial for the prognosis of breast cancer patients. The emergence of radiolabeled molecular probes targeting HER2 makes this assessment possible. This article describes different types of small-molecule probes that target HER2 and are used in current preclinical applications and summarizes their advantages and disadvantages.
