RESUMO

ABSTRACT: Sclerosing epithelioid fibrosarcoma (SEF) and low-grade fibromyxoid sarcoma (LGFMS) constitute a morphological continuum with certain overlapping histopathological features and MUC 4 immunopositivity. SEF is characterized by EWSR1 gene rearrangement, is relatively more aggressive and shows a limited response to chemotherapy. Lately, a subset of tumors with morphological features of SEF, but lacking MUC4 immunostaining and EWSR1 gene rearrangement have been observed. We report the first case of YAP1∷KMT2A-positive sarcoma from the Indian subcontinent along with a review of similar tumors reported previously. A case of 31-year-old male presented with a 3 cm painful lump in the right suboccipital region. Histopathological examination of the excised specimen revealed a cellular tumor composed of atypical spindle and epithelioid cells, exhibiting moderate nuclear pleomorphism, arranged in cords, embedded in a dense collagenous/hyalinized stroma. By immunohistochemistry, the tumor cells were diffusely positive for cyclin D1 and negative for MUC4, desmin, myogenin, ß-catenin, STAT6, myoD1, SMA, and S100P. By fluorescence in-situ hybridization, EWSR1 gene rearrangement was negative. Next-generation sequencing (NGS) revealed YAP1exon5∷KMT2Aexon4 fusion. Given a positive resection margin, he underwent a revision surgery involving wide local excision of the lesion including the outer table of the occipital bone followed by image-guided radiation therapy. Over 2 years of his follow-up, the patient is alive with no evidence of recurrence. Thus, YAP1∷KMT2A positive sarcomas have distinct molecular and overlapping histopathological features with SEF, with relatively less aggressive disease course. Documentation of additional similar tumors with long-term follow-up is required.

RESUMO

Background and objective Diffuse coronary artery disease (CAD) is associated with extensive involvement of coronary arteries, necessitating the use of long (≥40 mm) drug-eluting stents (DES) based on the lesion length. However, these long DES can lead to complications such as in-stent restenosis (ISR) and stent thrombosis. This study aimed to assess the safety, efficacy, and one-year clinical outcomes of using long DES in patients with diffuse CAD undergoing PCI at a tertiary care hospital in north India. Methodology Patients with diffuse CAD undergoing PCI with long DES between January 2017 and June 2022 were included in the study. Baseline characteristics were recorded, and patients were followed up telephonically or in the outpatient department (OPD) at one, three, six, and 12 months following the PCI. The primary endpoint was the target lesion failure (TLF) rate, with secondary endpoints constituting all-cause mortality, major adverse cardiovascular events (MACE), subacute stent thrombosis, and ISR. Results A total of 200 patients were recruited and followed up for one year. The median age of the patients was 58 years (range: 48.25-63 years), and 82% were men. The most frequently stented artery was the left anterior descending (LAD, 48%), followed by the right coronary artery (RCA, 36%). A total of 388 stents (mean: 1.94 ±0.79) were implanted, including both long and short stents. The mean length and diameter of long stents were 43.64 ±3.58 mm and 3 ±0.37 mm, respectively. At the one-year follow-up, patients undergoing PCI with long DES ≥40 mm had an overall TLF rate of 5%, all-cause mortality of 6% (12 patients), MACE of 6% (12 patients), subacute stent thrombosis of 4% (eight patients), and ISR of 1% (two patients). A large proportion of patients (90%) had an uneventful follow-up of up to a year. At the one-year follow-up, all 10 (5%) patients with a primary outcome had a smaller stent diameter than those without a primary outcome (2.5 ±0.25 mm vs. 3.03 ±0.35 mm, p=0.015). Conclusions Our results suggest that using extremely long stents (>40 mm) for diffuse coronary lesions is safe, efficacious, and associated with relatively low event rates. In addition, the stent diameter has a substantial correlation with the primary outcome. Further studies with larger sample sizes as well as longer follow-up periods are required to validate our findings.

RESUMO

PURPOSE: To compare the efficacy and safety of a thromboelastography (TEG)-guided platelet transfusion strategy to empirical or on-demand transfusions in patients with cirrhosis and severe thrombocytopenia (platelet counts <50 x109/L) undergoing high-risk invasive procedures. MATERIALS AND METHODS: This was a single-center, single-blinded, randomized controlled trial. Patients with cirrhosis and severe thrombocytopenia undergoing high-risk invasive procedures were randomized into three groups- TEG group: transfusions based on TEG parameters; SOC group: 3 units of random donor platelets pre-procedure; On-demand group: transfusions based on procedural adverse effects /clinician's discretion. The primary outcome was periprocedural platelet transfusion in each arm. RESULTS: Eighty-seven patients were randomized (29 in each group) with no significant differences in demographics/coagulation profile/procedures. The median platelet count was 33 x109/L (IQR: 26-43). Percutaneous liver biopsy was the most common procedure (46, 52.9%). Significantly lower number of patients in the TEG group received platelets (4 cases, 13.8%; 95%CI: 3.9-31.7) compared to SOC (100%; 95%CI: 88.1-100) (p<0.001). Four patients in the on-demand group received platelets (13.8%; 95%CI: 3.9-31.7). Minor (WHO grade 2) procedure-related bleeding occurred in 3 (10%; 95%CI: 2.2-27.4) patients in the TEG-guided transfusion group, compared to 1 (3.4%; 95%CI: 0.1-17.8) each in SOC and on-demand groups, respectively (p=0.43) although our sample size was underpowered for comparison of outcomes such as post-procedural bleeding. No bleeding-related mortality was observed in any of the three groups. CONCLUSION: Thromboelastography-guided transfusion reduces prophylactic transfusions in patients with cirrhosis and severe thrombocytopenia undergoing high-risk invasive procedures.

RESUMO

Chronic inflammation is central to the pathogenesis of many chronic inflammatory conditions. This review aims to analyze whether the practice of yoga, or yogic meditation and breathing, has any effect on the levels of inflammatory cytokines and other inflammatory markers in patients with various chronic inflammatory diseases such as rheumatoid arthritis, neoplastic disorders, and asthma, as well as in healthy subjects, compared to usual care or sham interventions. A comprehensive search of databases (PubMed, CENTRAL, Embase, and CINAHL) was performed. Randomized controlled trials (RCTs) that evaluated the effects of yoga as an intervention on inflammatory markers were analyzed. A total of 26 studies were included. Only two studies had a low risk of bias (RoB); 24 other studies had a high RoB. Most studies (n=24) reported a favorable outcome with yoga, irrespective of the type of yoga used, the condition studied, and the duration of the intervention. The commonly reported inflammatory markers included IL-6 (n=17), tumor necrosis factor-alpha (TNF-a) (n=13), and C-reactive protein (CRP) (n=10). Most studies showed a significant reduction in inflammatory markers in the yoga group (YG) compared to the control group (CG). Few studies also showed significant improvement in markers of cellular immunity (interferon gamma (IFN-g), IL-10, and transforming growth factor-beta (TGF-b); n=2 each) and improved mucosal defense (IgA, IL-6, and IL-2; n=2 each). A meta-analysis of IL-6, TNF-a, and CRP showed yoga had a favorable effect on the levels of these markers, but it was not statistically significant. Current evidence suggests that yoga can be a complementary intervention for various chronic inflammatory conditions. However, the quality of the evidence is poor, along with considerable heterogeneity. In the future, investigators should describe the intervention better, with a uniform assortment of outcome measures and treatment conditions, to generate high-quality evidence.

RESUMO

BACKGROUND & AIMS: Acute-on-chronic liver failure (ACLF) is a major public health concern. We aimed to assess the definitions, etiologic spectrum, organ failure (OF), and outcomes of ACLF globally. METHODS: Three databases were searched for studies on ACLF from 1990 until September 2022. Information regarding definitions, acute precipitants, underlying chronic liver disease (CLD), OF, and mortality were extracted. Meta-analyses were performed for pooled prevalence rates (95% confidence interval [CI]) using random-effects model for each definition of ACLF. RESULTS: Of the 11,451 studies identified, 114 articles (142 cohorts encompassing 210,239 patients) met the eligibility criteria. Most studies (53.2%) used the European Association for the Study of the Liver (EASL) definition, followed by Asia-Pacific Association for the Study of the Liver (APASL) (33.3%). Systemic infection was the major acute precipitant, and alcohol use was the major cause of CLD in EASL-defined studies, whereas alcohol was both the major acute precipitant and cause of CLD in APASL-defined studies. Liver failure was the major OF in APASL-based studies, whereas renal failure was predominant in EASL-based studies. Thirty-day mortality varied across definitions: APASL: 38.9%, 95% CI, 31.2%-46.9%; EASL: 47.9%, 95% CI, 42.2%-53.5%; and NACSELD: 52.2%, 95% CI, 51.9%-52.5%. Diagnostic overlap between definitions ranged from 7.7% to 80.2%. Meta-regression suggested that the World Health Organization region influenced 30-day mortality in studies using EASL definition. CONCLUSIONS: Heterogeneity in the definition of ACLF proposed by different expert societies and regional preferences in its use result in differences in clinical phenotype and outcomes. A uniform definition would enhance the comparability and interpretation of global data.

RESUMO

BACKGROUND: Variants in the TUBB4A gene are associated with dystonia (DYT-TUBB4A), Hypomyelination with Atrophy of the Basal Ganglia and Cerebellum (H-ABC) and spastic paraplegia. Phenotypes intermediate to these three broad phenotypes are also observed. These are rare disorders, and data from diverse populations remains limited. We report seven Indian cases with dystonia phenotype related to TUBB4A mutation. CASES: Among these seven patients, age at onset ranged from 5 to 48 years. Five patients had cranio-cervical onset of dystonia. One patient had prominent parkinsonism with dystonia. Patients responded well to botulinum toxin injected for laryngeal, cervical and jaw dystonia. The patient with parkinsonism responded well to levodopa, albeit with development of dyskinesias. Apart from the common p.Arg2Gly variant in three patients with DYT-TUBB4A, other variants included p.Arg262Pro, p.Arg39Cys and p.Asp245Asn. CONCLUSIONS: We report the first collection of cases with TUBB4A mutation from India. We expand the phenotype to include levodopa-responsive parkinsonism. Indian patients, consistent with global literature, harbor prominent adductor dysphonia, cervical and jaw dystonia, which responds well to botulinum treatment.

RESUMO

BACKGROUND: There is scant literature on hepatocellular carcinoma (HCC) in patients with Budd-Chiari syndrome (BCS). AIM: To assess the magnitude, clinical characteristics, feasibility, and outcomes of treatment in BCS-HCC. METHODS: A total of 904 BCS patients from New Delhi, India and 1140 from Mumbai, India were included. The prevalence and incidence of HCC were determined, and among patients with BCS-HCC, the viability and outcomes of interventional therapy were evaluated. RESULTS: In the New Delhi cohort of 35 BCS-HCC patients, 18 had HCC at index presentation (prevalence 1.99%), and 17 developed HCC over a follow-up of 4601 person-years, [incidence 0.36 (0.22-0.57) per 100 person-years]. BCS-HCC patients were older when compared to patients with BCS alone (P = 0.001) and had a higher proportion of inferior vena cava block, cirrhosis, and long-segment vascular obstruction. The median alpha-fetoprotein level was higher in patients with BCS-HCC at first presentation than those who developed HCC at follow-up (13029 ng/mL vs 500 ng/mL, P = 0.01). Of the 35 BCS-HCC, 26 (74.3%) underwent radiological interventions for BCS, and 22 (62.8%) patients underwent treatment for HCC [transarterial chemoembolization in 18 (81.8%), oral tyrosine kinase inhibitor in 3 (13.6%), and transarterial radioembolization in 1 (4.5%)]. The median survival among patients who underwent interventions for HCC compared with those who did not was 3.5 years vs 3.1 mo (P = 0.0001). In contrast to the New Delhi cohort, the Mumbai cohort of BCS-HCC patients were predominantly males, presented with a more advanced HCC [Barcelona Clinic Liver Cancer C and D], and 2 patients underwent liver transplantation. CONCLUSION: HCC is not uncommon in patients with BCS. Radiological interventions and liver transplantation are feasible in select primary BCS-HCC patients and may improve outcomes.

RESUMO

Aim and background: High-quality cardiopulmonary resuscitation (CPR) is associated with improved patient outcomes, but healthcare workers (HCWs) may be frequently undertrained. This study aimed to assess baseline knowledge and skills among HCWs about basic and advanced life support and the effect of simulation-based training on it. Methods: It was a single-center prospective quasi-interventional study among resident doctors and nurses at a Tertiary Center in New Delhi, India. A questionnaire-based assessment was done to assess baseline knowledge. The participants then underwent simulation-based training followed by questionnaire-based knowledge assessment and skill assessment. A repeat questionnaire-based assessment was done 6 months post-training to assess knowledge retention. Results: A total of 82 HCWs (54 doctors and 28 nurses) were enrolled. The participants scored 22.28 ± 6.06 out of 35 (63.65%) in the pre-training knowledge assessment, with low scores in post-cardiac arrest care, advanced life support, and defibrillation. After the training, there was a significant rise in scores to 28.32 ± 4.08 out of 35 (80.9%) (p < 0.01). The retention of knowledge at 6 months was 68.87% (p < 0.01). The participants scored 92.61 ± 4.75% marks in skill assessment with lower scores in chest compressions and team leadership roles. There was a positive correlation (r = 0.35) between knowledge and skills scores (p < 0.01). Conclusion: There is a progressive decrease in baseline knowledge of HCWs with the further steps in the adult chain of survival. The simulation training program had a positive impact on the knowledge of HCWs. The training programs should focus on defibrillation, advanced life support, post-cardiac arrest care, and leadership roles.

RESUMO

Stroke is the second leading cause of death and a major cause of disability worldwide. Stroke severity scales serve as reliable means to track a patient's neurological deficit, predict outcome, and guide treatment decisions in clinical practice. The National Institute of Health Stroke Scale (NIHSS) was introduced over 30 years ago, marking a significant milestone in the field of stroke. Over the years, there have been notable advancements in acute stroke care. Despite several modifications made to NIHSS, none has yet succeeded in effectively capturing all the complex effects of a stroke. This review focuses on the pitfalls of NIHSS and emphasizes the need for a quick and comprehensive clinical and upgraded version of the stroke severity rating scale.
