RESUMO

Meningioma is the most common type of primary brain tumor which presents with a variety of neurological manifestations. Surgical resection tends to be the preferred treatment. The occurrence of seizures after resection is common, which occur either early, within seven days of operation, or late. Our meta-analysis investigated the possible predictors of early and late postoperative seizures. We assessed the relevant observational studies on predictors of postoperative seizures published in PubMed, Scopus, and Web of Science from January 2000 to September 2022, and those that met inclusion criteria were included. We calculated the association between potential predicting factors and postoperative seizures, odds ratios (ORs) with 95% confidence intervals (CIs) applying either random or fixed-effect models. The early and late postoperative seizures were evaluated individually. Thirteen observational studies involving 4176 patients were included. Seizures occurred in 250 (6%) and 584 (14%) patients, respectively, in the early and late postoperative phases. Shared predictors for early and late seizures included tumors involving the motor cortex (OR = 2.7; 95% CI: 1.67-4.38, OR = 2.46; 95% CI: 1.68-3.61), postoperative neurological deficit (OR = 4.68; 95% CI: 2.67-8.22, OR = 2.01; 95% CI: 1.39-2.92), and preoperative seizures (OR = 2.52; 95% CI: 1.82-3.49, OR = 4.35; 95% CI: 3.29-5.75). Peritumoral edema (OR = 1.99; 95% CI: 1.49-2.64) was a significant factor only among late postoperative seizure patients while surgical complications (OR = 3.77; 95% CI: 2.39-5.93) was a significant factor solely for early postoperative seizures. Meningioma patients commonly experience early and late postoperative seizures. Identifying predictors of postoperative seizures is essential to diagnose and manage them effectively.

RESUMO

The objectives of this study are to evaluate caveolin-1 expression in endometrioid endometrial cancer and its correlation with clinicopathological parameters. Forty-four cases of endometrioid endometrial carcinomas underwent radical hysterectomy. The archived paraffin sections that were stained for caveolin-1 by immunohistochemistry, caveolin-1 expression were detected in cancerous epithelial cells in 18.2% of the cases, and stromal caveolin-1 was detected in 65.9% of the cases. Caveolin-1 expression in the epithelium showed a significant positive association with the T stage and the FIGO stage. Positive caveolin-1 expression in epithelium has a direct, positive and significant relationship with invasion of other organs and a direct and significant relationship with the advanced FIGO stage. As for caveolin-1 expression in the stroma, it showed a significant negative inversely significant association with myometrial invasion. Also, there is a significant negative association between caveolin-1 expression in the epithelium and its expression in the stroma. We conclude that caveolin-1 expression strongly plays a critical role in endometrioid endometrial carcinoma as a tumor suppressor or promoter of invasion. In early lesions, high stromal levels appear to be protective against progression. While decreased stromal expression and increased epithelial expression were associated with aggressive tumors.

RESUMO

The potential long-term neuropsychiatric effects of COVID-19 are of global concern. This study aimed to determine the prevalence and predictors of neuropsychiatric post-acute sequelae of COVID-19 among Egyptian COVID-19 survivors and to study the impact of full vaccination before COVID-19 infection on the occurrence and severity of these manifestations. Three months after getting COVID-19 infection, 1638 COVID-19 survivors were screened by phone for possible neuropsychiatric sequelae. Subjects suspected to suffer from these sequelae were invited to a face-to-face interview for objective evaluation. They were requested to rate the severity of their symptoms using visual analogue scales (VAS). The mean age of participants was 38.28 ± 13 years. Only 18.6% were fully vaccinated before COVID-19 infection. Neuropsychiatric post-acute sequelae of COVID-19 were documented in 598 (36.5%) subjects, fatigue was the most frequent one (24.6%), followed by insomnia (16.4%), depression (15.3%), and anxiety (14.4%). Moderate and severe COVID-19 infection and non-vaccination increased the odds of developing post-COVID-19 neuropsychiatric manifestations by 2 times (OR 1.95, 95% CI = 1.415-2.683), 3.86 times (OR 3.86, 95% CI = 2.358-6.329), and 1.67 times (OR 1.67, 95% CI = 1.253-2.216), respectively. Fully vaccinated subjects before COVID-19 infection (n = 304) had significantly lesser severity of post-COVID-19 fatigue, ageusia/hypogeusia, dizziness, tinnitus, and insomnia (P value = 0.001, 0.008, < 0.001, 0.025, and 0.005, respectively) than non-vaccinated subjects. This report declared neuropsychiatric sequelae in 36.5% of Egyptian COVID-19 survivors, fatigue being the most prevalent. The effectiveness of COVID-19 vaccines in reducing the severity of some post-COVID-19 neuropsychiatric manifestations may improve general vaccine acceptance.

RESUMO

BACKGROUND: Endoscopic resection can be used for removing colloid cysts as a substitute for open craniotomy. Cerebral vasospasm, a possible complication of the craniotomy procedure, has not been reported as a complication of endoscopic removal of colloid cysts. CASE DESCRIPTION: A 58-year-old man developed the worst headache of his life. The CT and MRI showed a 1.3 cm midline third ventricular cyst at the level of the foramen of Monro, consistent with a colloid cyst. The patient elected to undergo an endoscopic resection of the colloid cyst. The image-guided frameless stereotactic endoscopic colloid cyst resection proceeded without events. Postoperative MRI showed a gross total resection. The patient continued to improve until post-operative day #9 when he experienced an episode of slurred speech and several episodes of legs buckling. An MRI did not show a stroke. A CT angiogram showed diffuse vasospasm, including the basilar artery and bilateral middle cerebral arteries, when compared to the patient's preoperative MRA. The patient's antihypertensive medications were stopped. The patient was started on Nimodipine, 60 mg every 4 hours, and triple H therapy (Hypertension, Hypervolemia, and Hemodilution) was applied. His blood pressure rose and his neurologic exam improved over several days. The patient returned to his baseline in 14 days without any neurological deficits. To our knowledge, this is the first case report of a patient undergoing endoscopic colloid cyst resection that was complicated by diffuse cerebral vasospasm. CONCLUSIONS: We report the first case of acute, transient cerebral vasospasm following endoscopic resection of a colloid cyst.

RESUMO

ß-thalassemia is one of the most common inherited autosomal disorders in the northern Iraqi Kurdistan region. This study reports a rare mutation in the initiation codon of the ß-globin gene (HBB: c.2T > C; p.Met1Thr) in an 11-year-old male with severe transfusion-dependent ß-thalassemia. Molecular testing to uncover the mutations of the ß-globin gene in the proband and his parents was performed by amplification and reverse hybridization. Sanger sequencing was conducted for further identification. A severe ß-globin gene mutation in codon 8/9 [+G] was initially identified in the proband and his mother's DNA samples. However, the detection of only one ß-globin gene mutation was not enough to elucidate the patient's severe phenotype. Thus, a rare mutation in the initiation codon was identified later in the proband and his father by Sanger sequencing. In thalassemias, the presence of a rare mutation should be suspected when the patient's genotype does not correlate with the phenotype.

RESUMO

Social media has become an essential source of information during the coronavirus disease 2019 (COVID-19) pandemic. This study aims to understand social media's effect on the general public's fear, degree of adopting precautionary behaviors, and compliance with health authorities' regulations during the pandemic. A cross-sectional online survey was conducted in Jordan during the early period of COVID-19 pandemic. 827 individuals completed the questionnaire. Factors that had a significant association with increased fear included female gender (OR 2.6, 95% CI: 1.8-3.7), married status (OR 1.9, 95% CI: 1.2-3.4), following medical pages on social media (OR 1.6, 95% CI: 1.04, 2.42), and sharing of COVID-19 information on social media (OR 3.6, 95% CI: 1.8-7.1). The variables that were significantly associated with higher levels of precautionary behaviors were knowledge score (OR 1.2, 95% CI: 1.07-1.3), feeling of fear (OR 2.6, 95% CI: 1.71-3.), and following medical pages on social media (OR 2.8, 95% CI: 1.8-4.24). Regarding compliance with health officials' regulations, social media as a source of information and sharing information were significantly associated with lower odds of compliance with the Ministry of Health's regulations (OR 0.27, 95% CI: 0.13-0.5 and OR 0.46, 95% CI: 0.25-0.8, respectively). Social media is an essential platform for risk communication during pandemics. It plays a positive role in spreading knowledge and promotes certain preventive behaviors among the public. However, it may spread fear and encourage disruptive behaviors, which might be propagated by sharing the pandemic's news.

RESUMO

Background: COVID-19 pandemic has negatively impacted the psychological well-being and quality of life of health care providers (HCPs). Objectives: This study assessed the trends in prevalence and predictors of insomnia, burnout, and functional impairment among HCPs over the first year of the pandemic. Methods: An online survey was conducted one month after the pandemic's onset (onset group) and a year later (one-year group). The demographic features of participants were collected. Insomnia, burnout, and functional impairment were assessed using Insomnia Severity Index (ISI), Mini-Z survey, and Sheehan Disability Scale (SDS), respectively. Results: The onset group included 211 HCPs (mean (SD) age 34.7 (9.3) years and 73% men), while 212 HCPs participated in the one-year survey (mean (SD) age 35.9 (10.5) years and 69% men). High prevalence estimates were found in both onset and one-year groups of symptoms of insomnia (52% vs. 49%), of diagnosis of clinical insomnia (15% vs. 18%), with a high mean ISI score (8.4 vs. 8.7), but with no significant difference between the onset and one-year groups. Risk factors for clinical insomnia included age in both groups, lower income and contact level with COVID-19 patients/samples in the onset group, and lower Mini-Z scores and higher SDS scores in the one-year group. Approximately one-third of respondents reported at least one or more burnout symptoms, with a higher percentage in the one-year group (35.4%) than in the onset group (24.2%) (p=0.012). Younger age, lower monthly income, and higher ISI and SDS scores were risk factors for burnout in both groups. Greater perceived changes in social life were associated with burnout in the onset group. In contrast, higher weekly working hours, worse participants' evaluation of their institution's preparation, and more changes in workload were risk factors for burnout in the one-year group. The SDS score and its subscales scores were higher in the one-year group than in the onset group. Changes in workload and social life predicted higher SDS scores among both groups. Living with older people predicted higher SDS scores among the onset group, while contact level and estimated number of COVID-19 patients that participants engaged in during caring predicted higher SDS scores among the one-year group. ISI scores were significantly correlated with the Mini-Z scores and SDS scores in both groups, while the Mini-Z and SDS scores were significantly correlated only in the one-year group. Conclusion: This study demonstrated high rates of insomnia, burnout, and functional impairment among HCPs during the pandemic. It reveals a significant rise in job burnout and functional impairment of HCPs overtime during the pandemic. Furthermore, high-risk subgroups are also highlighted for whom comprehensive psychosocial and occupational interventions might be warranted.

RESUMO

Background: COVID-19 pandemic has an overwhelming psychologic burden on healthcare workers (HCWs). This study aims to investigate the changes in the prevalence, estimates, severity, and risk factors of depressive symptoms among HCWs within the first year of the COVID-19 pandemic. Methods: An observational e-survey collected data on HCWs' socio-demographic characteristics, occupational situation, and depressive symptoms as measured by Patient Health Questionnaire-9 (PHQ-9). The e-survey was distributed one month after the onset of the COVID-19 pandemic (onset group) and again after one year (one-year group). Results: A total of 422 HCWs were included (Mean (SD) age, 35.3 (9.9) years; 71.3% males), with 211 (50%) participants in each group. In the total cohort, the mean PHQ-9 score was 8.5, and 36.7% reported clinically significant levels of depressive symptoms with a PHQ-9 score of ≥10. Compared to the onset group, the one-year group reported a higher risk of major depressive disorder (41.7% vs. 31.8%; OR 1.538; 95%CI 1.032-2.291; p=0.034), a higher mean PHQ-9 score (9.5 (6.8) vs. 7.4 (5.3), p<0.001), and more severe depressive symptoms (p<0.005). Participants who were younger, unmarried, underwent testing for COVID-19, reported lower monthly income, did not receive special COVID-19 education, or had lower satisfaction with institutional preparedness had significantly higher depression scores and symptoms in both onset and one-year groups (p<0.05 for each category). Female gender and direct contact with COVID-19 patients or samples were significant risk factors within the onset group. Occupation as a physician, history of COVID-19 testing or infection, and perception of significant changes in work schedule or intensity were significantly associated with higher depression scores and symptoms among the one-year group. Conclusion: This study sheds light on an unspoken but significant rise in prevalence estimates and severity of depressive symptoms among HCWs over a year of the COVID-19 pandemic and shows the vulnerable subgroups for whom a psychological intervention might be warranted.

RESUMO

Up to 30% of patients with epilepsy may not respond to antiepileptic drugs. Patients with drug-resistant epilepsy (DRE) should undergo evaluation for seizure onset zone (SOZ) localization to consider surgical treatment. Cases of drug-resistant nonlesional extratemporal lobe epilepsy (ETLE) pose the biggest challenge in localizing the SOZ and require multiple noninvasive diagnostic investigations before planning the intracranial monitoring (ICM) or direct resection. Ictal Single Photon Emission Computed Tomography (i-SPECT) is a unique functional diagnostic tool that assesses the SOZ using the localized hyperperfusion that occurs early in the seizure. Subtraction ictal SPECT coregistered to MRI (SISCOM), statistical ictal SPECT coregistered to MRI (STATISCOM), and PET interictal subtracted ictal SPECT coregistered with MRI (PISCOM) are innovative SPECT methods for the determination of the SOZ. This article comprehensively reviews SPECT and sheds light on its vital role in the presurgical evaluation of the nonlesional extratemporal DRE.

RESUMO

BACKGROUND: Bleeding complications and acute limb ischemia (ALI) are devastating vascular complications in patients with ST-segment elevation myocardial infarction (STEMI). Cardiogenic shock (CS) can further increase this risk due to multiorgan failure. In the contemporary era, percutaneous mechanical circulatory support is commonly used for management of CS. We hypothesized that vascular complications may be an important determinant of clinical outcomes for CS due to STEMI (CS-STEMI). OBJECTIVE: We evaluated 10-year national trends, resource utilization and outcomes of bleeding complications, and ALI in CS-STEMI. METHODS: We performed a retrospective cohort study of CS-STEMI patients from a large U.S. national database (National Inpatient Sample) between 2005 and 2014. Events were then divided into four different groups: no MCS, with intra-aortic balloon pump, percutaneous ventricular assist device includes Impella or Tandem Heart or extracorporeal membrane oxygenation. RESULTS: Bleeding complications and ALI were observed in 31,389 (18.2%) and 1,628 (0.9%) out of 172,491 admissions with CS-STEMI, respectively. Between 2005 and 2014, overall trends increased for ALI; however, the number of bleeding events decreased. ALI was associated with increased in-hospital mortality in comparison to those without any ALI. However, bleeding complications were not associated with increased in-hospital mortality. Compared to patients without complications, both bleeding and ALI were associated with increased length of stay (LOS) and hospitalization costs. CONCLUSIONS: Bleeding and ALI are common complications associated with CS-STEMI in the contemporary era. Both complications are associated with increased hospital costs and LOS. These findings highlight the need to develop algorithms focused on vascular safety in CS-STEMI.

RESUMO

OBJECTIVE: The authors sought to evaluate 10-year national trends, incidence and clinical outcomes of stroke in CS-STEMI. BACKGROUND: Stroke is a devastating complication among patients with ST-elevation myocardial infarction (STEMI). Concomitant cardiogenic shock (CS) may further increase the risk of stroke. Use of percutaneous mechanical circulatory support (pMCS) devices may further increase stroke risk in CS-STEMI. No studies have evaluated the risk of stroke in contemporary CS-STEMI. METHODS: We performed a retrospective cohort study of CS-STEMI patients from a large U.S. national database between 2005 and 2014. Previously validated codes for stroke were used to identify events of ischemic or hemorrhagic stroke. They were then divided into different groups: without MCS, with intra-aortic balloon pump, percutaneous ventricular assist device (PVAD, includes Impella or TandemHeart devices), or extracorporeal membrane oxygenation. RESULTS: In 172,491 admissions, stroke was noted in 5,613 (3.2%). Between 2005 and 2014, we observed an increase in the events of overall stroke from 3.1% in 2005 to 5.0% in 2014 (p for the trend <.001). The number of ischemic stroke events (2.4%) was higher than hemorrhagic stroke (0.1%) during the study period. Presence of stroke was associated with higher in-hospital mortality (40.6 vs. 29.8%, 95% CI adjusted odds ratio: 1.57, 1.44-1.67; p < .0001 among stroke vs. without stroke). CONCLUSIONS: The incidence of stroke events in CS-STEMI patients increased between 2005 and 2014, and is associated with higher in-hospital mortality, length of stay, and cost of hospitalization. The incidence of both hemorrhagic and ischemic stroke was higher with pMCS device use. Stroke prevention is a priority for CS-STEMI patients.

RESUMO

BACKGROUND: The spectrum of neurological involvement in COVID-19 is not thoroughly understood. To the best of our knowledge, no systematic review with meta-analysis and a sub-group comparison between severe and non-severe cases has been published. The aim of this study is to assess the frequency of neurological manifestations and complications, identify the neurodiagnostic findings, and compare these aspects between severe and non-severe COVID-19 cases. METHODS: A systematic search of PubMed, Scopus, EBSCO, Web of Science, and Google Scholar databases was conducted for studies published between the 1st of January 2020 and 22nd of April 2020. In addition, we scanned the bibliography of included studies to identify other potentially eligible studies. The criteria for eligibility included studies published in English language (or translated to English), those involving patients with COVID-19 of all age groups, and reporting neurological findings. Data were extracted from eligible studies. Meta-analyses were conducted using comprehensive meta-analysis software. Random-effects model was used to calculate the pooled percentages and means with their 95% confidence intervals (CIs). Sensitivity analysis was performed to assess the effect of individual studies on the summary estimate. A subgroup analysis was conducted according to severity. The main outcomes of the study were to identify the frequency and nature of neurological manifestations and complications, and the neuro-diagnostic findings in COVID-19 patients. RESULTS: 44 articles were included with a pooled sample size of 13,480 patients. The mean age was 50.3 years and 53% were males. The most common neurological manifestations were: Myalgia (22.2, 95% CI, 17.2 to 28.1%), taste impairment (19.6, 95% CI, 3.8 to 60.1%), smell impairment (18.3, 95% CI, 15.4 to 76.2%), headache (12.1, 95% CI, 9.1 to 15.8%), dizziness (11.3, 95% CI, 8.5 to 15.0%), and encephalopathy (9.4, 95% CI, 2.8 to 26.6%). Nearly 2.5% (95% CI, 1 to 6.1%) of patients had acute cerebrovascular diseases (CVD). Myalgia, elevated CK and LDH, and acute CVD were significantly more common in severe cases. Moreover, 20 case reports were assessed qualitatively, and their data presented separately. CONCLUSIONS: Neurological involvement is common in COVID-19 patients. Early recognition and vigilance of such involvement might impact their overall outcomes.

RESUMO

This project aims to prepare hydrogel microneedle patches (MNs) as a painless method to deliver carbamazepine transdermally. This can be used as a sustained release system that offers the advantages of lower gastrointestinal side effects and avoids the first-pass metabolism of the drug. MNs were composed of two medicated layers, a microneedle layer and a base layer. MNs were fabricated using polyvinyl alcohol with or without polyvinylpyrrolidone Kollidon 30 as a matrix polymer and in the presence of selected solubilizing agent (polyethylene glycol 400, Tween 80, or α-tocopherol polyethylene glycol). Freezing-thawing cycle was evaluated as one of the processing parameters that may affect the drug release. The MNs were evaluated for their weight variation, base thickness, and content uniformity. The physicochemical compatibility between carbamazepine and the polymers was estimated by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, and X-ray powder diffraction. Evaluation for the in vitro release studies and ex vivo permeation studies was performed. The prepared MNs were flexible, clear, and uniform in weight, base thickness, and drug content. Physicochemical characterizations showed that carbamazepine was amorphous in most of the MNs. In vitro release and ex vivo permeation studies of carbamazepine were significantly higher for MNs containing a combination of 1:1 w/w of PEG 400 and Tween 80 as solubilizing agents where the release was extended over 96 h, with the release of 85.2% and 59.6% permeation percentage compared to other MNs. A significant effect of the freezing-thawing cycle on the release profile of the drug was observed. The hydrogel MNs are shown to be stable under the studied storage conditions.

RESUMO

BACKGROUND: Current literature clearly outlines the complication rates of liposuction in general; however, data specific to large-volume liposuction (LVL) remain unclear. OBJECTIVES: The authors aimed to synthesize the current evidence on the safety of LVL with this systematic review. METHODS: A comprehensive search in the MEDLINE, EMBASE, and CENTRAL databases was conducted for primary clinical studies reporting on safety or complications related to aesthetic LVL from 1946 to March 2020. The primary outcome measure was the incidence of surgical complication, and the secondary outcome measure was changes in metabolic profile. Meta-analyses were conducted to pool the estimated surgical complication incidence and metabolic changes. RESULTS: Twenty-three articles involving 3583 patients were included. The average aspirate volume was 7734.90 mL (95% CI = 5727.34 to 9742.45 mL). The pooled overall incidence of major surgical complications was 3.35% (95% CI = 1.07% to 6.84%). The most common major complication was blood loss requiring transfusion (2.89% [95% CI = 0.84% to 6.12%]) followed by pulmonary embolism (0.18% [95% CI = 0.06% to 0.33%]), hematoma (0.16% [95% CI = 0.05% to 0.32%]), necrotizing fasciitis (0.13% [95% CI = 0.04% to 0.29%]), and deep vein thrombosis (0.12% [95% CI = 0.03% to 0.27%]). No fat embolism or death was reported in the included studies. The pooled overall incidence of minor surgical complication was 11.62% (95% CI = 6.36% to 18.21%), with seroma being the most common minor complication (5.51% [95% CI = 2.69% to 9.27%]). Reductions in lipid profile, glucose profile, body weight, and hematocrit level were observed after LVL. CONCLUSIONS: The authors meta-analyzed and highlighted the complication rates specifically related to LVL in this study; however, the current data are limited by the lack of level 1 evidence.

RESUMO

BACKGROUND: HbH disease results from dysfunction of three, less commonly two, α-globin genes through various combinations of deletion and non-deletion mutations. Characterization of the mutations and the underlying genotypes is fundamental for proper screening and prevention of thalassaemia in any region. The aim of this study was to explore the genetic arrangements of HbH disease and to correlate the genotypes with the clinical phenotypes. METHODS: A total of 44 HbH disease patients were enrolled in this study. They were clinically and haematologically assessed. The patients were tested for 21 common α-globin gene mutations using multiplex PCR and reverse hybridization. According to the genotype, the patients were categorized into two separate sub-groups, deletion and non-deletion types HbH disease. RESULTS: Within the studied HbH disease patients, eight different α-globin gene mutations were detected in nine different genetic arrangements. The --MED and -α3.7 deletions were the two most frequently encountered mutations (37.5 and 35.2% respectively). Patients with deletion genotypes constituted 70.4%. The most common detected genotype was --MED/-α3.7 (59.1%), followed by αpoly-A1α/αpoly-A1α (13.6%). For the first time, coinheritance of two relatively mild mutations (-α3.7/ααAdana) was unpredictably detected in a 1.5 year-old child with Hb of 7.1 g/dL. CONCLUSION: The HbH disease patients' clinical characteristics were variable with no ample difference between the deletion and non-deletion types. These results can be of benefit for the screening and management of thalassaemia in this region.

RESUMO

BACKGROUND: Multiple sclerosis (MS) is a neurological disease that is caused by an autoimmune response that results in the neuron's demyelination in the central nervous system. The exact etiology of MS is not clear; however, several environmental and genetic factors are believed to participate in its initiation and development, including exposure to viruses. This study aims to investigate the association between the seropositivity and antibody titer of selected herpesviruses and MS in Jordanian MS patients. METHOD: In this study, 55 MS patients and 40 age- and gender-matching apparently healthy volunteers were recruited from two main hospitals in the north of Jordan. MS patients were grouped into three types of MS based on the clinical presentation of the disease. Blood samples were collected from the participants and the IgG antibodies for human herpesvirus 6 (HHV-6), Epstein-Barr virus (EBV) nuclear antigen (EBNA), EBV viral capsid antigen (VCA) and varicella-zoster virus (VZV) were assayed by ELISA. The prevalence of seropositivity and the antibody level for each of the antibodies were compared between MS patients and controls and between the three types of MS. RESULTS: There was no significant difference in the prevalence of seropositivity and in the levels of antibodies for HHV-6, EBNA and VCA between MS patients and controls and between the three types of MS. In contrast, the number of seropositive patients and the level of IgG antibodies for VZV were significantly higher in MS patients compared to the control. CONCLUSION: This study showed that patients with MS in the north of Jordan were more likely to be seropositive for VZV than the general population. Based on this finding, we recommend further studies to evaluate the seropositivity to VZV to be carried out in other parts of Jordan and the greater middle east to find out if there is a correlation between MS and previous infection with VZV.

RESUMO

BACKGROUND: Myocarditis may be associated with hemodynamic instability and portends a poor prognosis when associated with cardiogenic shock (CS). There are limited data available on the incidence of in-hospital mortality, CS, and utilization of mechanical circulatory support (MCS) devices in these patients. METHODS: We queried the 2005-2014 National Inpatient Sample databases to identify all patients aged >18 years with myocarditis in the United States. RESULTS: The number of reported cases of myocarditis per 1 million gradually increased from 95 in 2005 to 144 in 2014 (Pfor trend <.01). The trend and incidence of endomyocardial biopsy remained the same despite the increase in clinical diagnosis. Overall, in-hospital mortality was 4.43% of total admissions without a change in overall trend over the study period. We also observed a significant increase in the incidence of CS from 6.94% in 2005 to 11.99% in 2014 (Pfor trend <.01). There was a parallel increase in the utilization of advanced MCS devices during the same time period such as extracorporeal membrane oxygenation or percutaneous cardiopulmonary support (0.32% in 2005 to 2.1% in 2014; P< .01) and percutaneous ventricular assist devices such as Impella/tandem heart (0.176% in 2005 to 1.75% in 2014; P< .01). CONCLUSION: Although the incidence of myocarditis has increased in the last decade, the in-hospital mortality has remained the same despite increases in the incidence of CS, possibly reflecting the benefits of increased usage of advanced MCS devices. We noted that increasing age, presence of multiple comorbidities and CS were associated with an increase in in-patient mortality.

RESUMO

BACKGROUND: Periprocedural outcomes of transcatheter mitral valve repair (TMVR) with Mitraclip in patients with pulmonary hypertension (PH) are not well studied. METHODS: Patients who underwent TMVR with Mitraclip between 2011 and 2015 were identified using the National Inpatient Sample (NIS). All missing variables were excluded from the analysis and therefore, complete case analysis was performed. RESULTS: A total of 1,037 patients underwent TMVR with Mitraclip between 2011 and 2015. The prevalence of PH in these patients was 32.6%. In-hospital outcomes were compared between PH group and non-PH group. Inpatient mortality after TMVR was similar between the two groups (3.2% vs. 2.1%, OR 1.57, P = 0.335). There was no statistical significance between the two groups in the rates of hemorrhage requiring transfusion (8.5% vs. 7.2%, OR 1.17, P = 0.587), cardiogenic shock (4.4% vs. 4.5%, OR 0.98, P = 0.951), acute respiratory failure (15.2% vs. 13.1%, OR 1.23, P = 0.460), postoperative sepsis (2.75% vs. 3.9%, OR 0.66, P = 0.340), postoperative deep vein thrombosis or pulmonary embolism (2.7% vs. 3.9%, OR 1.98, P = 0.348). In addition, non-routine home discharge, median hospital cost and length of stay were similar between the two groups. CONCLUSION: Pre-existing PH in patients undergoing TMVR with Mitraclip does not adversely affect in-hospital outcomes in this cohort of patients. Therefore, PH does not carry a prohibitive risk in selecting patients for Mitraclip procedure.

RESUMO

BACKGROUND: Aspirin (ASA) is the most used medication on the globe. ASA is a primary pillar of the secondary prevention of cardiovascular atherothromboembolic events. However, a fraction of the population does not respond to ASA as expected in a unique phenomenon called ASA resistance. Multiple mechanisms were described and studied in the literature to explain this phenomenon. AREA OF UNCERTAINTY: ASA resistance is an interesting phenomenon that is worth studying and reviewing. Mechanisms behind this resistance are various and although the rarity of some, it is crucial for the modern health provider to be aware of such phenomenon and its possible explanations to provide more efficient preventive cardiology practice. Our study aimed to review and conclude the evidence behind ASA resistance and its implication on the cardiovascular health. DATA SOURCES: We searched databases like PubMed, EMBASE, Ovid by midline, and Google Scholar for published articles and abstracts. RESULTS: Our systemic search revealed more than 100 articles in relation to ASA resistance. We selected 40 articles, which were relevant for this review. Various mechanisms were described in the literature, with few of them very well documented and understood. Main mechanisms include medication nonadherence, interaction with proton pump inhibitors, esterase-mediated ASA inactivation, post-coronary artery bypass grafting (CABG) MRP-4-mediated ASA consumption, cyclooxygenase-1 (COX-1) polymorphisms, high platelet turnover-associated regeneration of platelet COX-1, and the documented platelet ability of de novo COX-1 synthesis in response to thrombin and fibrinogen. CONCLUSION: Multiple mechanisms of ASA resistance were described in the literature. Awareness of such interaction is important for medical practitioners. Bottom line, further studies and reviews are needed to further study this phenomenon and its implication on the cardiovascular health and hence reaching a valid evidence-based conclusion that might change the practice and improve the patient preventive health care.

RESUMO

The diagnosis of psychogenic nonepileptic seizures (PNES) remains challenging. In the correct clinical setting with prolonged electroencephalography (EEG) monitoring, the specificity of provocative techniques to distinguish induced epileptic event from a nonepileptic event approaches 90%. We report our epilepsy monitoring unit (EMU) experience with the use of noninvasive verbal suggestion (VS) during hyperventilation (HV), photic stimulation (PS) as induction technique in making the diagnosis of PNES. In total, 189/423 patients were diagnosed with PNES during the EMU evaluation. Of the 189, 20 had mixed disorder and 169 patients had only PNES, 80 patients (47.3%) had a PNES with induction, and the remaining 89 of 169 patients (52.7%) had a spontaneous PNES episode that did not require induction. Verbal suggestion during HV and PS confirmed the diagnosis of PNES in 47% of the patients who otherwise did not have spontaneous events. Within the group who was diagnosed with PNES following induction, antiepileptic drugs (AEDs) were stopped in 53% of the patients. We believe that this is a large proportion of patients that would possibly remain undiagnosed if no induction were performed.
