RESUMO
There is an established literature on the symptoms and complications of COVID-19 but the after-effects of COVID-19 are not well understood with few studies reporting persistent symptoms and quality of life. We aim to evaluate the pooled prevalence of poor quality of life in post-acute COVID-19 syndrome (PCS) and conducted meta-regression to evaluate the effects of persistent symptoms and intensive care unit (ICU) admission on the poor quality of life. We extracted data from observational studies describing persistent symptoms and quality of life in post-COVID-19 patients from March 10, 2020, to March 10, 2021, following PRISMA guidelines with a consensus of two independent reviewers. We calculated the pooled prevalence with 95% confidence interval (CI) and created forest plots using random-effects models. A total of 12 studies with 4828 PCS patients were included. We found that amongst PCS patients, the pooled prevalence of poor quality of life (EQ-VAS) was (59%; 95% CI: 42%-75%). Based on individual factors in the EQ-5D-5L questionnaire, the prevalence of mobility was (36, 10-67), personal care (8, 1-21), usual quality (28, 2-65), pain/discomfort (42, 28-55), and anxiety/depression (38, 19-58). The prevalence of persistent symptoms was fatigue (64, 54-73), dyspnea (39.5, 20-60), anosmia (20, 15-24), arthralgia (24.3, 14-36), headache (21, 3-47), sleep disturbances (47, 7-89), and mental health (14.5, 4-29). Meta-regression analysis showed the poor quality of life was significantly higher among post-COVID-19 patients with ICU admission (p = 0.004) and fatigue (p = 0.0015). Our study concludes that PCS is associated with poor quality of life, persistent symptoms including fatigue, dyspnea, anosmia, sleep disturbances, and worse mental health. This suggests that we need more research on PCS patients to understand the risk factors causing it and eventually leading to poor quality of life.

INTRODUCTION: Antimicrobial resistance (AMR) is an emerging global threat. It increases mortality and morbidity and strains healthcare systems. Health care professionals can counter the rising AMR by promoting antibiotic stewardship and facilitating new drug development. Even with the economic and scientific challenges, it is reassuring that new agents continue to be developed. METHODS: This review addresses new antibiotics in the pipeline. We conducted a review of the literature including Medline, Clinicaltrials.org, and relevant pharmaceutical companies for approved and in pipeline antibiotics in phase 3 or new drug application (NDA). RESULTS: We found a number of new antibiotics and reviewed their current development status, mode of action, spectra of activity, and indications for which they have been approved. The included studies from phase 3 clinical trials were mainly utilized for the treatment of acute bacterial skin and skin structure infections, community-acquired bacterial pneumonia, and pneumonia acquired in the healthcare settings. The number of these agents is limited against high priority organisms. The identified antibiotics were based mainly on previously known molecules or pre-existing antimicrobial agents. CONCLUSION: There are a limited number of antibiotics against high priority organisms such as multi-drug-resistant Pseudomonas aeruginosa, and carbapenem-resistant Enterobacteriaceae. New antimicrobial agents directed against the top priority organisms as classified by the World Health Organization are urgently needed.

INTRODUCTION: COVID-19 vaccines have been developed to compact the current SARS-CoV-2 pandemic and have been administered to people all over the world. These vaccines have been quite effective in reducing the possibility of severe illness, hospitalization and death. However, the recent emergence of Variants of Concern specifically the delta variant, B.1.617.2, had resulted in additional waves of the pandemic. METHODS: We aim to review the literature to understand the transmission and disease severity, and determine the efficacy of the current COVID-19 vaccines. We searched Pubmed, Scopus, and Embase till August 4th 2021, and used the search terms "delta variant", "vaccinations"," breakthrough infections", and "neutralizing antibody". For the meta-analysis, 21 studies were screened in particular and five articles (148,071 cases) were included in the study, and only four were analyzed in the meta-analysis. RESULTS: In this review, both in vitro and in vivo studies showed significant reductions in neutralization rates against delta variants for vaccinated individuals and convalescent patients with prior history of COVID-19. However, There was a lower incidence of infection with SARS-CoV-2 due to Delta variant was found after the second dose of Pfizer-BioNTech, Oxford-AstraZeneca and Moderna vaccines. CONCLUSION: In fully vaccinated individuals, symptomatic infection with the delta variant was significantly reduced, and therefore, vaccinations play an important role to assist the fight against delta variant.

BACKGROUND: The recent emergence of the Coronavirus Disease (COVID-19) disease had been associated with reports of fungal infections such as aspergillosis and mucormycosis especially among critically ill patients treated with steroids. The recent surge in cases of COVID-19 in India during the second wave of the pandemic had been associated with increased reporting of invasive mucormycosis post COVID-19. There are multiple case reports and case series describing mucormycosis in COVID-19. PURPOSE: In this review, we included most recent reported case reports and case-series of mucormycosis among patients with COVID-19 and describe the clinical features and outcome. RESULTS: Many of the mucormycosis reports were eported from India, especially in COVID-19 patients who were treated and recovered patients. The most commonly reported infection sites were rhino-orbital/rhino-cerebral mucormycosis. Those patients were diabetic and had corticosteroids therapy for controlling the severity of COVID-19, leading to a higher fatality in such cases and complicating the pandemic scenario. The triad of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), corticosteroid use and uncontrolled diabetes mellitus have been evident for significant increase in the incidence of angioinvasive maxillofacial mucormycosis. In addition, the presence of spores and other factors might play a role as well. CONCLUSION: With the ongoing COVID-19 pandemic and increasing number of critically ill patients infected with SARS-CoV-2, it is important to develop a risk-based approach for patients at risk of mucormycosis based on the epidemiological burden of mucormycosis, prevalence of diabetes mellitus, COVID-19 disease severity and use of immune modulating agents including the combined use of corticosteroids and immunosuppressive agents in patients with cancer and transplants.

Backgroundand Objectives: COVID-19 is a novel infectious disease caused by a single-stranded RNA coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We aimed to conduct a nationwide multicenter study to determine the characteristics and the clinical prognostic outcome of critically ill COVID-19 patients admitted to intensive care units (ICUs). Materials and Methods: This is a nationwide cohort retrospective study conducted in twenty Saudi hospitals. Results: An analysis of 1470 critically ill COVID-19 patients demonstrated that the majority of patients were male with a mean age of 55.9 ± 15.1 years. Most of our patients presented with a shortness of breath (SOB) (81.3%), followed by a fever (73.7%) and a cough (65.1%). Diabetes and hypertension were the most common comorbidities in the study (52.4% and 46.0%, respectively). Multiple complications were observed substantially more among non-survivors. The length and frequency of mechanical ventilation use were significantly greater (83%) in the non-survivors compared with the survivors (31%). The mean Sequential Organ Failure Assessment (SOFA) score was 6 ± 5. The overall mortality rate of the cohort associated with patients that had diabetes, hypertension and ischemic heart disease was 41.8%. Conclusion: Age; a pre-existing medical history of hypertension, diabetes and ischemic heart disease; smoking cigarettes; a BMI ≥ 29; a long mechanical ventilation and ICU stay; the need of ventilatory support; a high SOFA score; fungal co-infections and extracorporeal membrane oxygenation (ECMO) use were key clinical characteristics that predicted a high mortality in our population.

E-cigarettes have been known to cause varied poor health outcomes prior to coronavirus disease 2019 (COVID-19), but after the impact of COVID-19, evidence came out that was, in some instances, not as expected regarding the severity of COVID-19 among e-cigarette users (vapers). A meta-analysis was performed on the available evidence to comprehensively find the effect of COVID-19 on existing or past e-cigarette users (vapers). The Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines were used to perform this meta-analysis. PubMed was searched for observational studies that described outcomes after COVID-19 positivity from December 1, 2019, to December 2023. Medical Subject Headings (MeSH) keywords were used for searching the relevant studies highlighting the relationship between COVID-19 and e-cigarette users. Calculations for pooled prevalence, 95% confidence interval (95% CI), weights for current e-cigarette users and vapers, and outcomes (events) were made. To analyze the data, Review Manager V.5.4 was used. The I² statistic was used to assess statistical heterogeneity. The I² statistic of >50% was considered significant heterogeneity. The "leave-one-out" method was used for sensitivity analysis. Out of 3231 studies, four studies reported data on vaping and non-vaping status and composite outcomes, resulting in a sample size of 653 COVID-19-positive cases. The pooled prevalence of being COVID-19 positive, having symptoms, or visiting an emergency room was 7.78% (653/8392). COVID-19 patients with current vaping status had decreased odds of poor outcomes compared to non-smokers, with a pooled odds ratio (OR) of 0.09 (95% CI 0.00-2.42; p>0.05) with heterogeneity between studies (I²=99%, p=0.15). Because of difficulties related to data collection and other factors, this meta-analysis was unable to conclusively establish the correlation between e-cigarette usage and severe COVID-19 outcomes such as hospitalization, admission to the intensive care unit, and fatality. Additional research using more detailed data is necessary to fully understand this correlation.
RESUMO
Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi, a Gram-negative bacillus, commonly occurring in the Asia-Pacific region. It is transmitted to humans by the bite of an infected Leptotrombidium mite and the bacterium causes endothelial dysfunction resulting in widespread vasculitis and the possible development of thrombocytopenia, meningitis, acute respiratory distress syndrome, and infrequently, myocarditis. Early diagnosis and prompt treatment are crucial in managing scrub typhus. Here, we present four cases of scrub typhus with a comprehensive literature review. This study highlights the significance of considering scrub typhus as a possible diagnosis in patients of all ages from endemic regions who exhibit symptoms such as fever, thrombocytopenia, or transaminitis, even in the absence of typical clinical features. Two cases exhibited the characteristic lesion of eschar at the site of mite feeding. One case involved a middle-aged woman who was diagnosed with typhus-induced myocarditis with left ventricular dysfunction. Another case involved a 23-day-old neonate with poor feeding and seizures, who was diagnosed with late-onset sepsis with meningitis. Scrub typhus was confirmed in all cases using a positive qualitative IgM ELISA. However, it is preferred to use paired (ELISA before and after antibiotic therapy) or quantitative titers for confirmation. Healthcare providers must consider the patient's exposure history and clinical presentation to diagnose and treat scrub typhus promptly.
RESUMO
Multiple cranial nerve palsies frequently accompany hypoglossal nerve palsy, potentially indicating malignancy, such as lymphoma, nasopharyngeal carcinoma, or metastases. However, when solely the hypoglossal nerve is affected, the causes may involve Chiari malformation, arachnoid cyst, or infectious mononucleosis, suggesting a positive prognosis. Craniocervical junction tuberculosis (TB), is an uncommon cause of isolated hypoglossal nerve palsy and has been reported infrequently in the literature. Craniocervical junction tuberculosis accounts for only 0.5% of TB cases overall and 6% of extra-pulmonary TB cases. We present here one such case of a 17-year-old male of Indian origin with a subacute history of tongue deviation and neck pain. Additionally, the patient reported loss of weight and appetite. The patient had significant posterior cervical lymphadenopathy. Neurological examination revealed findings suggestive of right peripheral hypoglossal nerve involvement. Blood investigations showed lymphocytosis along with an elevated erythrocyte sedimentation rate of 45 mm/h and elevated lactate dehydrogenase levels of 325 U/L. Tuberculin skin testing was positive and sputum acid-fast staining confirmed acid-fast bacilli. Magnetic Resonance Imaging of the cervical spine revealed a soft tissue component in the prevertebral space measuring 3.5×4.8 cm with a right paraspinal component adjoining the hypoglossal canal with peripheral contrast enhancement. Histological findings on the lymph node showed granulomatous lymphadenitis, suggestive of tuberculosis. The patient was started on 4-drug anti-tubercular therapy consisting of Isoniazid, Rifampicin, Pyrazinamide, and Ethambutol for a period of 18 months. He was subsequently followed up for 6 months till the resolution of palsy. This case emphasizes the importance of thorough evaluation and a meticulous workup to identify the underlying cause of hypoglossal nerve palsy and the importance of considering tuberculosis as a potential cause of isolated hypoglossal nerve palsy in everyday practice.
RESUMO
The primary aim of this study was to evaluate epidemiological characteristics and prevalence of lung disease among e-cigarettes users in the United States. A population-based, cross-sectional survey was performed using the National Health and Nutrition Examination Survey (NHANES) of 2015-2018. Adults using e-cigarettes (SMQ900), traditional smoking (SMQ020: > 100 cigarettes in lifetime or SMQ040: current cigarettes use), and dual smoking (e-cigarettes and traditional smoking) were identified and compared in their sociodemographic characteristics and prevalence of lung diseases (Asthma: MCQ010 and COPD: MCQ160O). We used the chi square test (categorical variables) and Mann-Whitney test and unpaired-student t test (continuous variables). p-value <0.05 was used as a reference. We excluded respondents <18 years and missing data on demographics and outcomes. Out of 178,157 respondents, 7745 (4.35%), 48,570 (27.26%), and 23,444 (13.16%) were e-cigarette smokers, traditional smokers, and dual smokers, respectively. Overall prevalence of asthma was 15.16% and COPD was 4.26%. E-cigarette smokers were younger in comparison to traditional smokers (median: 25 years vs 62 years; p < 0.0001). In females (49.34% vs 37.97%), Mexican (19.82% vs 13.35%), annual household income above $100,000 (23.97% vs 15.56%), prevalence of e-cigarette smoking was higher in comparison to traditional smoking (p < 0.0001). The prevalence of COPD was higher among dual smokers in comparison to e-cigarette and traditional smoking (10.14% vs 0.25% vs 8.11%; p < 0.0001). Prevalence of asthma was higher among dual and e-cigarette smokers in comparison with traditional smokers and non-smokers (22.44% vs 21.10% vs 14.46% vs 13.30%; p < 0.0001). Median age (Q1-Q3) was lower at which asthma (7 years (4-12) vs 25 years (8-50)) was diagnosed first among e-cigarettes smokers in comparison with traditional smokers. In a mixed effect multivariable logistic regression analysis, we found higher odds of asthma among e-cigarette users in comparison with non-smokers (Odds ratio (OR): 1.47; 95% Confidence Interval (CI): 1.21-1.78; p = 0.0001). Chronic Obstructive Pulmonary Disease (COPD) respondents were also associated with 11.28 higher odds of e-cigarette utilization (Oddsratio (OR): 11.28; 95% Confidence Interval (CI): 5.59-22.72; p < 0.0001). We conclude the higher prevalence of e-cigarette users is seen among the younger population, female, Mexican race, and annual income above $100,000 in comparison to traditional smokers. Chronic Obstructive Pulmonary Disease (COPD) and asthma were both more prevalent in dual smokers. As asthma was more prevalent and diagnosed at an early age in e-cigarette smokers, more prospective studies are needed to understand the effects of e-cigarette among the population at risk to mitigate the sudden rise in utilization and to create awareness.

Poliomyelitis is caused by Poliovirus, a member of a large group of enteroviruses. Vaccine-derived polioviruses (VDPVs) stem from mutated live poliovirus, which is contained in the Oral Polio Virus vaccine (OPV). In addition, the emergence of VDPV is one of the global challenges for the eradication of poliomyelitis. VDPVs continue to affect different parts of the world; 1081 cases occurred in 2020 and 682 cases in 2021. There are several reasons that may have caused the increase in circulating vaccine-derived poliovirus (cVDPV) after the "switch" from the trivalent to the bivalent oral polio vaccine. One reason is the low vaccination rate among the targeted population, which has been further aggravated by the COVID-19 pandemic. Several strategies could control the spread of VDPV including the use of the monovalent OPV (mOPV-2). The risk of VDPV can be minimized through increased immunization rates and the use of safer vaccine alternatives. The global effort to eradicate polio has made significant progress over the years, but continued vigilance and investment in immunization programs are needed to achieve the ultimate goal of a polio-free world.
RESUMO
Asthma affects 7% of children and 8% of adults in the United States. There is a paucity of studies examining the association between passive smoking and an increased risk of asthma exacerbations that led the authors to examine the association between various modes of smoking and rates of asthma exacerbations. A retrospective cross-sectional/case-control study was conducted using the National Health and Nutrition Examination Survey dataset (2013-2018). Out of 312,979 respondents, 35,758 (11.43%) had a history of asthma, 9083 (2.9%) had asthma attacks in the past year, and 4731 (1.51%) had asthma-related emergency room admissions in the past year. Prevalence of asthma-related emergency admissions were higher among active cigarette smoking (46.25 vs 35.46%), e-cigarette smoking (26.63 vs 16.07%), and passive smoking at home (37.53 vs 25.67%), workplace passive smoking (14.35 vs 12.11%), in bar (32.38 vs 26.16%), and car (26.21 vs 14.44%) (p < 0.0001). In multivariate regression analysis, we found regular cigarette smoking (OR 1.13, 95% confidence interval (CI) 1.009-1.260, p = 0.0252), e-cigarette (OR 2.13, 95% CI 1.92-2.36, p = 0.0043), cigar use (OR 1.21, 95% CI 1.1-1.33, p < 0.001), ultra-long cigarette length (OR 4.85, 95% CI 3.33-7.06, p < 0.0001), and passive smoking (OR 5.25, 95% CI 3.43-8.06, p < 0.0001) were associated with increased rates of asthma exacerbations over last 12 months. The study shows increased odds of asthma exacerbations among those using ultra-long cigarettes, e-cigarettes, and cigars. Consequently, passive inhalation from even a single smoker in the home, workplace, bars and cars is associated with worsening outcomes in asthma patients.
RESUMO
Importance: Practice guidelines often provide recommendations in which the strength of the recommendation is dissociated from the quality of the evidence. Objective: To create a clinical guideline for the diagnosis and management of adult bacterial infective endocarditis (IE) that addresses the gap between the evidence and recommendation strength. Evidence Review: This consensus statement and systematic review applied an approach previously established by the WikiGuidelines Group to construct collaborative clinical guidelines. In April 2022 a call to new and existing members was released electronically (social media and email) for the next WikiGuidelines topic, and subsequently, topics and questions related to the diagnosis and management of adult bacterial IE were crowdsourced and prioritized by vote. For each topic, PubMed literature searches were conducted including all years and languages. Evidence was reported according to the WikiGuidelines charter: clear recommendations were established only when reproducible, prospective, controlled studies provided hypothesis-confirming evidence. In the absence of such data, clinical reviews were crafted discussing the risks and benefits of different approaches. Findings: A total of 51 members from 10 countries reviewed 587 articles and submitted information relevant to 4 sections: establishing the diagnosis of IE (9 questions); multidisciplinary IE teams (1 question); prophylaxis (2 questions); and treatment (5 questions). Of 17 unique questions, a clear recommendation could only be provided for 1 question: 3 randomized clinical trials have established that oral transitional therapy is at least as effective as intravenous (IV)-only therapy for the treatment of IE. Clinical reviews were generated for the remaining questions. Conclusions and Relevance: In this consensus statement that applied the WikiGuideline method for clinical guideline development, oral transitional therapy was at least as effective as IV-only therapy for the treatment of IE. Several randomized clinical trials are underway to inform other areas of practice, and further research is needed.

Strongyloides stercoralis and Trichuris trichiura parasitic infections are two of the many neglected tropical diseases. These parasitic infections are of considerable public health relevance, particularly in resource-limited countries. Moxidectin, a well-established drug in veterinary medicine, is now a Food and Drug Administration (FDA) approved medication for human onchocerciasis. For the past five years, this medication has been under clinical trials to evaluate its efficacy and safetiness in other helminthic infections. Moxidectin might complement the already existing treatment and control of soil-transmitted helminthiasis (STH). Therefore, we systematically reviewed existing human interventional studies to evaluate the efficacy and safety of this medication when administered alone or in combination with other antiparasitic medications in order to achieve a cure.
RESUMO
Gastric cancer (GC) is one of the most common malignancies throughout the world with late diagnosis and poor prognosis. The expression of programmed death-ligand 1 (PD-L1) in GC is attributed to immune evasion and tumor progression. PD-L1 positivity has both predictive and prognostic biomarker potential. Aiming to summarize a large amount of research and to provide a definitive conclusion to the conflicting results on the prognostic significance of PD-L1 expression in GC, we performed an umbrella review based on existing meta-analyses which were published recently (2016-2021) and indexed in the PubMed database. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was used in August 2021 to screen articles, and data extraction with quality assessment was performed on the selected meta-analyses. Review Manager (RevMan) 5.3 software was used to analyze the HR and OR with a 95% confidence interval (CI) among PD-L1 positive GC patients. We also assessed the between-study heterogeneity (I 2). Forest and Funnel plots were obtained, and a P-value of <0.05 was considered statistically significant. A total of 567 articles were screened, and we selected three meta-analyses with a total of 40 studies conducted over a period of 14 years. In our umbrella review, a total of 8,419 GC patients with an average PD-L1 positivity of 39% were analyzed. We found that PD-L1 positivity in GC patients is associated with poor prognosis (pooled HR =1.44, 95% CI: 1.24-1.68, P<0.00001) having higher mortality reducing the chances of overall survival (OS). However, there are no significant differences in PD-L1 expression among different lymph node (LN) metastases (OR=1.31, 95% CI: 0.98-1.74, P=0.07) and tumor, node, and metastasis (TNM) stages (OR=1.13, 95% CI: 0.80-1.58, P=0.50). Early identification of PD-L1 expression may help tailor cost-effective and targeted immunotherapy among GC patients. More research is needed to further understand how PD-L1 affects LN metastasis and tumor invasion.
RESUMO
Mortality risk stratification can identify patients with COVID-19 who are at higher risk of mortality, discharge to skilled nursing facility, and readmission, and may benefit from focused intervention strategies.

Human African trypanosomiasis (HAT), or sleeping sickness disease, is an infection caused mainly by Trypanosoma brucei gambiense-human African trypanosomiasis (g-HAT) and is transmitted by tsetse flies. The disease goes through two stages: hemolymphatic and meningo-encephalic phases. The treatment for the second stage has changed from melarsoprol or eflornithine to nifurtimox-eflornithine combination therapy (NECT) and fexinidazole. We aimed to systematically review the literature on the efficacy and toxicity of fexinidazole and NECT. We used PubMed advanced strategy and Google Scholar databases, including clinical trials and observational studies on humans in the last 20 years in the English literature. Applying the inclusion/exclusion criteria, we reviewed eight studies. We used Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) protocol. For assessing bias, we used the Cochrane Collaboration's tool for risk assessment of the clinical trials and the Robins-I tool for the observational studies. Overall, the clinical trials showed that NECT was non-inferior to eflornithine. The proportion of patients discharged alive is higher in patients treated with NECT vs. patients treated with eflornithine. Gastrointestinal complaints are a common side effect of NECT therapy, while fearful but relatively rare convulsions can also occur. The main limitation among the studies of NECT was the lack of blinding because most of them were open-label. Fexinidazole, the new oral medication showed is effective and safe for the treatment of g-HAT infection. Because of their convenience, fexinidazole is preferred over NECT therapy, oral vs. IV infusion in the first and second stages of the disease. Compared to older therapies, fexinidazole and NECT are more effective and safer than eflornithine and melarsoprol monotherapy.
RESUMO
Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne virus endemic to a vast geographical area spanning from Africa to the shores of the Mediterranean Sea and north to the Balkans. The infection carries a high case fatality rate, which prompts the development of new treatment and prophylactic measures. This review explores the different treatment and prophylactic measures found in recent literature. For this purpose, we used Medical Subject Headings (MeSH) as well as PubMed advanced search. The inclusion criteria included full-text studies conducted on humans and in the English language. We found that plasma exchange was associated with a decrease in mortality rates. Similarly, the use of immunoglobulins proved effective in decreasing the severity and mortality risk. Ribavirin use was determined as a post-exposure prophylaxis drug with no statistically significant difference in oral or intravenous routes of administration. More studies should be conducted on CCHF as the number of outbreaks and endemic areas seem to be on the rise. For the time being, supportive therapy along with adjuvant antivirals appear to be the main course of management of CCHF. However, the need for definitive therapeutic agents and guidelines is warranted.
RESUMO
COVID-19 pandemic affected the lives of many with its devastating mortality and morbidity. Acquisition of herd immunity is one way to mitigate the spread of infection. Many factors influence the acceptance of vaccination including the regulatory process of the vaccines. This review article will briefly summarize the Emergency Use Authorization, Full FDA Approval process and highlight how the key factors affecting the vaccination hesitancy, are being influenced by the lack of Full FDA Approval.
RESUMO
Introduction Approximately 5-10% of strokes occur in adults of less than 45 years of age. The rising prevalence of stroke risk factors may increase stroke rates in young adults (YA). We aimed to compare risk factors and outcomes of acute ischemic stroke (AIS) among YA. Methods Adult hospitalizations for AIS and concurrent risk factors were found in the Nationwide Inpatient Sample database. Weighted analysis using chi-square and multivariable survey logistic regression was performed to evaluate AIS-related outcomes and risk factors among YA (18-45 years) and older patients. Results A total of 4,224,924 AIS hospitalizations were identified from 2003 to 2014, out of which 198,378 (4.7%) were YA. Prevalence trend of YA with AIS showed incremental pattern over time (2003: 4.36% to 2014: 4.7%; pTrend<0.0001). In regression analysis, the risk factors associated with AIS in YA were obesity (adjusted odds ratio {aOR}: 2.26; p<0.0001), drug abuse (aOR: 2.56; p<0.0001), history of smoking (aOR: 1.20; p<0.0001), infective endocarditis (aOR: 2.08; p<0.0001), cardiomyopathy (aOR: 2.11; p<0.0001), rheumatic fever (aOR: 4.27; p=0.0014), atrial septal disease (aOR: 2.46; p<0.0001), ventricular septal disease (aOR: 4.99; p<0.0001), HIV infection (aOR: 4.36; p<0.0001), brain tumors (aOR: 7.89; p<0.0001), epilepsy (aOR: 1.43; p<0.0001), end stage renal disease (aOR: 2.19; p<0.0001), systemic lupus erythematous (aOR: 3.76; p<0.0001), polymyositis (aOR: 2.72; p=0.0105), ankylosis spondylosis (aOR: 2.42; p=0.0082), hypercoagulable state (aOR: 4.03; p<0.0001), polyarteritis nodosa (aOR: 5.65; p=0.0004), and fibromuscular dysplasia (aOR: 2.83; p<0.0001). Conclusion There is an increasing trend in AIS prevalence over time among YA. Both traditional and non-traditional risk factors suggest that greater awareness is needed, with prevention strategies for AIS among young adults.
