Fine Needle Aspiration Cytology of Giant Cell Tumour of Tendon Sheath

Introduction: Giant Cell Tumour of Tendon Sheath (GCTTS), also known as localised nodular tenosynovitis, is a slow growing benign soft tissue tumour arising from synovium of tendon sheath, bursa or joint. Clinically, the lesions occur as skin-coloured nodules typically on the extremities. These tumours occur more frequently on the upper limbs especially hands (77%) where they form the second most common tumour following simple ganglion cyst. Aim: To describe the cytomorphologic findings in GCTTS and their histopathological features. Materials and Methods: This retrospective study was conducted at Department of Pathology, ESI Hospital, Delhi, India, in 12 diagnosed GCTTS cases for their cytological features from January 2015 to December 2017. Fine Needle Aspiration Cytology (FNAC) was performed with a 22-gauge needle attached to a 10 mL syringe. Smears were air-dried and stained with Giemsa stain. Cytomorphology of all the selected cases were analysed and descriptive statistics were used to evaluate the cases. Results: A total of 12 cases of GCTTS were retrieved. Diagnosis of GCTTS was made by FNAC in all the cases and confirmed by histopathological examination in half of the cases. The mean age of presentation was 39 years. Of these, 8 (66.67%) were women and 4 (33.33%) were men. The lesions were found most commonly over the index finger (n=5) followed by the ring finger (n=3), thumb (n=2), middle finger (n=1) and little finger (n=1). The most frequent clinical presentation was a painless, nodular, slow growing firm swelling over the finger. FNAC revealed cellular smears with few clusters and numerous scattered stromal cells along with interspersed multinucleated giant cells. Conclusion: A definitive preoperative diagnosis of GCTTS obtained through FNAC helps in formulating appropriate treatment plan. Histopathologic examination will confirm the cytological diagnosis and can help to predict recurrence by providing information on the resection margin, any satellite nodules, variable cell types and mitotic activity.

Assessment of prescribing pattern of drugs and completeness of prescriptions as per the World Health Organization prescribing indicators in various Indian tertiary care centers: A multicentric study by Rational Use of Medicines Centers-Indian Council of Medical Research network under National Virtual Centre Clinical Pharmacology activity

OBJECTIVE

The rational use of medicines as per the World Health Organization (WHO) should be practiced globally. However, data regarding the completeness of the prescriptions and their rational use is lacking from developing countries like India. Thus, the aim of this study was to assess the prescribing patterns of drugs and completeness of prescriptions as per WHO core drug use and complementary indicators to provide real-life examples for the Indian Council of Medical Research (ICMR) online prescribing skill course for medical graduates.

METHODS

Prescriptions of the patients, fulfilling inclusion criteria, attending Outpatient Departments of various specialties of tertiary care hospitals, were collected by thirteen ICMR Rational use of medicines centers located in tertiary care hospitals, throughout India. Prescriptions were evaluated for rational use of medicines according to the WHO guidelines and for appropriateness as per standard treatment guidelines using a common protocol approved by local Ethics committees.

RESULTS

Among 4838 prescriptions, an average of about three drugs (3.34) was prescribed to the patients per prescription. Polypharmacy was noted in 83.05% of prescriptions. Generic drugs were prescribed in 47.58% of the prescriptions. Further, antimicrobials were prescribed in 17.63% of the prescriptions and only 4.98% of prescriptions were with injectables. During the prescription evaluation, 38.65% of the prescriptions were incomplete due to multiple omissions such as dose, duration, and formulation.

CONCLUSION

Most of the parameters in the present study were out of the range of WHO-recommended prescribing indicators. Therefore, effective intervention program, like training, for the promotion of rational drug use practice was recommended to improve the prescribing pattern of drugs and the quality of prescriptions all over the country.

Epidemiological and diagnostic aspects of feline leishmaniasis with emphasis on Brazil: a narrative review

The leishmaniases are a group of diseases caused by the protozoan parasite belonging to the genus Leishmania. In the New World, although dogs are considered the main parasite reservoir, in the last two decades, several studies have confirmed the role of cats (Felis catus) in the epidemiology of the disease and feline leishmaniasis (FeL) is now considered to be an emerging disease. The present review summarizes the current knowledge about FeL, focusing on important immunopathological aspects, epidemiology, and diagnostic methods applied for felines in Brazil. Cats are infected with the same species of Leishmania found in dogs (i.e., Leishmania infantum). Like dogs, skin lesions are the most common in cats with clinical FeL, mainly affecting the cephalic region and less frequently the legs which may be accompanied by generalized signs or visceral involvement. Information on the immune response of cats to Leishmania infection is scarce; however, efficient infection control is seen in most cases. For diagnosis, generally, the same methods as those in dogs are used, mainly serological tools. But there is a lack of studies focusing the performance of these methods for diagnosing FeL. The estimated overall prevalence of FeL in Brazil is 8%, with L. infantum being the most prevalent species. However, infections with Leishmania braziliensis and Leishmania amazonensis have also been reported. In conclusion, although there has been an increase in the publication related to FeL in Brazil in recent years, there is a lack of research relating immune response and diagnosis of these animals. Cats have been shown to be competent hosts for Leishmania parasites, and their role in the epidemiology of the disease cannot be underestimated, especially in areas of Brazil where the disease is historically endemic.

With optimized fiber components (e.g. passively cooled pump laser diode, pump coupler, pump stripper), high power multimode pump light is coupled to the active fiber without any noticeable thermal degradation and an average gain of 18 dB and noise figure of 5.4 dB are obtained with an average differential modal gain of 3.4 dB.

Multicentric Hospital-Based Surveillance of Pertussis Amongst Infants Admitted in Tertiary Care Facilities in India

OBJECTIVE

To estimate the disease and economic burden of pertussis amongst hospitalised infants in India.

DESIGN

Multicentric hospital-based surveillance study.

PARTICIPANTS

Hospitalised infants with clinical suspicion of pertussis based on predefined criteria.

OUTCOME MEASURES

Proportion of infants with laboratory-confirmed pertussis, economic burden of pertussis amongst hospitalised infants.

RESULTS

693 clinically suspected infants were recruited of which 32 (4.62%) infants had laboratory-confirmed pertussis. Progressive cough with post-tussive emesis (50%) and pneumonia (34%) were the common clinical presentations; apnea in young infants was significantly associated with pertussis. Infants with pertussis were more likely to be younger (median age 102.5 days vs.157 days) and born preterm (42.9% vs 24.5%). Almost 30% infants with pertussis had not received vaccine for pertussis with 50% of these infants aged less than 2 months. Pertussis was associated with higher costs of hospitalisation, pharmacy and loss of working days by caregivers as compared to non-pertussis cases.

CONCLUSIONS

Younger infants, those born preterm and those inadequately immunised against pertussis are at higher risk of pertussis infection. Timely childhood immunisation and introduction of maternal immunisation for pertussis can help in reducing the disease burden.

AB0276 HOW FAST CAN METHOTREXATE BE ESCALATED IN RHEUMATOID ARTHRITIS? A MULTICENTRE, PARALLEL-GROUP RANDOMIZED CONTROLLED TRIAL (MEIRA)

Background:

Literature regarding the optimal dose escalation strategy of methotrexate (MTX) in RA is scant and ambiguous (1). Concerns regarding the safety of rapid escalation may lead to delayed attainment of the optimal dose and treatment target.

Objectives:

To compare the efficacy, safety and tolerability of fast versus usual dose escalation of oral MTX in RA.

Methods:

This multicenter, open-label (assessor blinded) RCT included patients with active RA (SJC≥2 and TJC≥4) aged 18-55 years, not on DMARDs (except HCQ and/or low-dose prednisolone) and with disease duration <5 years. Patients were randomized 1:1 into two groups with the same starting dose of oral MTX (15 mg/week), but escalated either by 5 mg every 2 weeks (fast escalation group) or 5 mg every 4 weeks (usual escalation group), till a maximum of 25 mg/wk. Primary outcome was proportion of EULAR good responders at 16 weeks. Secondary outcomes were change in DAS28-3 and EULAR responders (good or moderate) at 8 and 16 weeks, change in Indian HAQ at 16 weeks, and symptomatic (questionnaire based) and laboratory adverse effects over 16 weeks. RBC MTX polyglutamate-3 levels were measured using HPLC in both groups. There was an open-label extension phase till 24 weeks (use of other DMARDs was permitted beyond 16 weeks if target was not met), and DAS28-3 at 24 weeks was compared.

Trial Reg: CTRI/2018/12/016549

Results:

178 patients (mean age 39.8 (8.6) years, 84% females) with mean disease duration of 1.9 (1.4) years were randomized (89 in each group). Mean DAS28ESR-3 and DAS28CRP-3 at enrollment were 6.3 (0.9) and 5.4 (1.1). At 16 weeks, there was no significant difference in good EULAR response by DAS28ESR-3 (5.6, 7.9%, p=0.9) or DAS28CRP-3 (28.1, 22.5%, p=0.8) between the two groups (Figure 1). The change in DAS28-ESR-3 at 8, 16 and 24 weeks (or by DASCRP-3, not shown) and improvement in HAQ at 16 weeks were also not significantly different (Table 1). Notably, there was no significant difference in symptomatic GI or CNS adverse effects, incidence of cytopenia, transaminitis or rates of drug discontinuation. RBC MTX polyglutamate-3 levels at 8 and 16 weeks were also similar (Table 1).

EULAR response and change in DAS28ESR-3 over time

Conclusion:

A faster escalation of MTX (5 mg every 2 weeks) reaching 25 mg/week by 4 weeks did not have a significantly higher rate of adverse effects (symptomatic or laboratory) compared to an escalation by 5 mg every 4 weeks. Although not more efficacious, it may shorten the time to recognize MTX failure, and optimize treat-to-target.

POS0679 A NEW QUESTIONNAIRE AND SCORE (MISA) FOR ASSESSING METHOTREXATE INTOLERANCE IN RHEUMATOID ARTHRITIS

Background:

Methotrexate (MTX) intolerance refers to unpleasant symptoms that accompany use of MTX and may lead to its discontinuation. However, it lacks a validated score in RA patients; with the only option being to use the MISS score which was validated for use in children and not adults.

Objectives:

To develop and validate a questionnaire and score (s) for measuring MTX intolerance and its severity in rheumatoid arthritis.

Methods:

A 10-item questionnaire called ‘Methotrexate Intolerance and Severity assessment in Adults’ (MISA) was validated in 105 RA patients. A score was calculated by adding the scores of first 7 questions (0 to 3 based on severity on symptoms), to last 3 questions (0 or 1); it ranged from 0 to 24 (MISA score) and was assessed for correctly classifying MTX intolerance (compared to an interview) by ROC analysis. Its area-under-curve (AUC) was compared with ‘Methotrexate Intolerance Severity Score’ (MISS), developed for children. Subsequently, it was administered to 414 RA patients to assess the prevalence and associations of MTX intolerance. In addition, the MISA cross-products score, that was calculated by adding the cross-products (severity (1 to 3) x duration per week (0.5 to 7 days)) of symptoms, was compared to MISA and MISS for assessing severity of intolerance.

Results:

In the initial phase, 105 RA patients on MTX≥6 months were included, a majority were female (87%), mean age was 51 (13.4) years and methotrexate dose was 18.8±6 mg/week. Thirty-five (33%) were found to be intolerant to MTX based on interview. MISA score had a good predictive ability (AUC of 0.904), to correctly classify MTX intolerance, and was better than MISS score (AUC of 0.823) (Figure 1A). The optimal cut-off for MISA was ≥1, with a sensitivity and specificity of 91.4% and 84.3%. Using the MISA score (≥1), 38.4% of 414 RA patients were found to have MTX intolerance: with nausea, lethargy and irritability being common symptoms. (Figure 1B, C) On multivariable analysis, age (OR 0.972) and BMI (OR 1.061) were significant predictors of MTX intolerance. (Table 1) On assessing for severity of intolerance, MISA cross product score performed the best, with an area-under-curve of 0.899 (95% CI 0.831-0.966), being higher than AUC for MISS and MISA score which were 0.847 (95% CI 0.768-0.927) and 0.837 (95% CI 0.754-0.920).

Conclusion:

MISA is the first validated questionnaire for assessing methotrexate intolerance in rheumatoid arthritis, with the MISA score having a good accuracy (at cut-off ≥1), to detect MTX intolerance. Methotrexate intolerance was present in more than one-third of RA patients, with nausea, lethargy and irritability being most common.

Mental health impact of covid on athletes

Introduction

The coronavirus pandemic continues to impact all aspects of the daily life of the public worldwide. With decreased economic activity, the sports industry faces significant challenges of maintaining athletes’ mental health while seeking the best strategies for eventual return to sports competition.

Objectives

We aim to evaluate COVID-19 related factors impacting on the mental health of athletes and provide appropriate management steps.

Methods

We examined MeSH terms “Athletes,” “Sports,” “COVID-19,” in the context of “Mental Health,” “Mental Disorders,” “Behavioral Medicine,” “Risk Factors.” We identified seven studies for the qualitative synthesis per the PRISMA guidelines, searching Medline, PubMed, PubMed Central, and PsychInfo databases until July 2020.

Results

The pandemic has negatively impacted athletes’ mental wellbeing due to decreased physical activities, limited resources, fears, and delays or cancellations of the sporting event. The negative psychological impact on athletes is due to self-isolation measures leading to worries of less preparedness for the lockdown, reduced physical activity, loss of competitive advantages, fear of being infected, social isolation, and loneliness. During this period, athletes struggled to maintain baseline routine and engaged in excessive calorie intake, eating low-quality food, substance use, and sleep disruption. It has caused anxiety, depression, PTSD, and mood disorder at varying degrees of severity in athletes.

Conclusions

Limited resources during a pandemic have caused adverse mental impact on athletes. We recommend improving physical activity through confined or virtual training programs with colleagues. A collaborative approach is required by clinicians, psychologists, coaches, sports organizations, government bodies to limit the pandemic’s mental health impact.

Comparative Efficacy of Cow Milk, KNO3, and Warm Saline Rinses in Treating Dentin Hypersensitivity Following Nonsurgical Periodontal Treatment: A Randomized Controlled Trial

AIM

This study aimed to assess the desensitizing efficacy of commercially available cow milk compared to potassium nitrate (KNO₃) mouthwash and warm saline rinses after nonsurgical periodontal treatment.

MATERIALS AND METHODS

A randomized controlled trial was conducted in the Department of Public Health Dentistry of a dental college from August 21, 2018 to September 10, 2018. A total of 75 patients who reported hypersensitivity after scaling and root planing (SRP) were recruited and randomly assigned into three groups: cow milk (I), KNO₃ mouthwash (II), and warm saline rinses (III). Dentine hypersensitivity (DH) was assessed at six time points using the verbal rating scale (VRS) for thermal stimuli and visual analog scale (VAS) for air blast and thermal stimuli. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY). Mean reduction in DH in each group was measured using non-parametric tests.

RESULTS

Patients in all the three groups were found to be comparable with respect to baseline characteristics. Mean reduction in VRS and VAS scores for DH in milk and KNO₃ mouthwash was found to be significantly high as compared to warm saline rinses group.

CONCLUSION

From the results, cow milk was found to be equivalent in efficacy as compared with KNO₃ mouthwash but superior to warm saline rinses in treating DH post-SRP.

Practical consensus recommendations regarding the management of sentinel lymph node issues in early breast cancer

Axillary lymph node involvement is a very important poor prognostic factor in the clinical staging and management of breast cancer patients. Traditionally, axillary lymph node dissection (ALND) has been used for determining the status of the axillary lymph nodes. More recently the sentinel lymph node biopsy (SLNB) procedure has gained wider acceptance as the standard of care, having the advantage of being less invasivewhile providing good accuracy. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations in regards with the use of the two different procedures and other issues in patients with early breast cancer for the benefit of community oncologists.

Practical consensus recommendations regarding the use of hormonal therapy in metastatic breast cancer

Metastatic breast cancer (MBC) is cancer that has spread from the breast to another part of the body or has come back in another distant location. Treatment options for MBC depend on several factors. One of these factors is the levels of hormone receptors (HRs) in the tumor. Cancers with high levels of HRs, called HR-positive, use the hormones estrogen and progesterone to grow and spread. Hormonal therapy is a type of treatment specifically for HR-positive breast cancer. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations in regards with the use of hormonal therapy and the management of HR-positive MBC for the benefit of community oncologists.

Incidental Anaplastic Lymphoma in a Case of Herpetic Hepatitis

Introduction/Objective

The role of Herpes Simplex Virus (HSV) virus in the development of lymphomas is unclear and poses a diagnostic challenge along with limited literature explaining the relationship between HSV and Anaplastic large-cell lymphoma (ALCL).

Methods

A 26-year-old female admitted for intractable fever (103.7 F), chills, and dysuria; her urine analysis was suggestive of a mild urinary tract infection. During the admission, she developed abdominal pain with subsequent CT- scan showing thickening of the gallbladder and possible cholecystic fluid. Her liver function tests were: albumin 2.8 g/dL, AST 394 U/L, ALT 303 U/L, ALP 156 U/L, total bilirubin 0.3 INR 1. A subsequent Magnetic Resonance Cholangiopancreatography (MRCP) showed heterogeneous enhancement pattern of the liver without any masses following which she underwent cholecystectomy, during which her liver was abnormal along with an enlarged peri- cholic lymph node. Intraoperative biopsy of the liver showed patchy hepatocyte necrosis and occasional hepatocytes with ground-glass nuclei. The morphologic features were suggestive for Herpes Simplex Virus (HSV) hepatitis, and an HSV immunohistochemical stain confirmed this diagnosis. Removal of the lymph node showed a sinusoidal infiltrate of atypical lymphohistiocytic cells with abundant pale cytoplasm and large moderately irregular nuclei and occasional prominent amphophilic nucleoli. A few “hallmark”-like cells with curved nuclei were noted with rare mitosis. A panel of adequately controlled immunohistochemical stains showed positivity for CD4, CD30 (variable), and CD45. CD2, CD3, CD5, CD7, CD8, CD10, CD15, CD20, CD68 (positive in adjacent macrophages), BCL2, ALK1 were negative.

Results

Flow cytometry was negative for a neoplastic leukocyte population with a polytypic B-cell population. Taken together, a diagnosis of ALK1 negative, ALCL was made. A subsequent CT scan revealed borderline enlarged para- aortic lymph nodes along with an increased number of non-enlarged lymph nodes in the bilateral axillary, mediastinal, lower neck, and subpectoral regions. A bone marrow biopsy performed was negative for lymphoma.

Conclusion

Off note, her hepatitis serology panel, CMV, and HIV screens were negative. Thus, with her unusual presenting symptoms and no signs of malignancy led to numerous workups, which further led to an infectious cause, however, the patient was ultimately discovered to have an occult ALCL.

A Rare Case of Chronic Lymphoproliferative Disorder of NK Cells with an Unusual Expression of CD57

Introduction/Objective

Natural Killer cells (NK-cells) malignancies are extremely rare and the two NK-cell disorders involving the peripheral blood and bone marrow include chronic lymphoproliferative disorder of NK-cells (CLPDNK) and aggressive NK-cell leukemia (ANKL). ANKL is EBV associated with a prevalence in Asian adults and a fulminant clinical course leading to death within 2 months.

Methods

A 76-year-old female with a history of iron deficiency anemia presented for evaluation of lymphocytosis (78 TH/mm) and negative EBV with extreme fatigue, weight loss, and worsening weakness from the past 8 months.

Results

The peripheral and bone marrow aspirate showed an increase in granular lymphocytes with bland nuclei and abundant pale-staining cytoplasm containing fine to coarse azurophilic granules with no evidence of nuclear atypia. Flow cytometry demonstrated an atypical lymphocytic cell population comprising &gt;50% of total marrow and peripheral blood lymphocytes demonstrating loss of CD56 and diminished CD7 expression. The analysis showed atypical lymphocytes with the following immunophenotype: CD2, CD8 (the majority, at least 75%),CD7 (dim), CD38, CD11c (subset) with no expression of CD3, CD5, CD4, CD56, or CD11c. Flow cytometry is important as it helps in the phenotypic detection of aberrancy. A broad panel of immunohistochemical stains revealed scattered positivity for CD3, CD4, CD7, CD8, TIA-1, granzyme, perforin, and tryptase and negative for CD56 and CD57. Our top differential with a similar clinical course included T-cell large granular lymphocytic leukemia which is characterized by a clonal proliferation of mature cytotoxic T cells and also has an indolent course. They show CD3 positivity by flow cytometry along with co-expression of NK cell-associated markers (CD16 and CD57), and variable expression of other pan T cell markers such as CD2, CD5, CD7. It is found incidentally in patients having cytopenias with a persistent increase in circulating mature NK-cells. Of note, the PET scan revealed splenomegaly with no other significant findings.The patient was started on steroids and is currently doing well.

Conclusion

Thus, overall morphologic, immunophenotypic, and molecular results with negative expression of surface or cytoplasmic CD3 as well as the absence of TCR expression were most consistent with CLPD-NK with an unusual expression of CD57 expression detected in flow cytometry.

Risk Factors for Revision of Polished Taper-Slip Cemented Stems for Periprosthetic Femoral Fracture After Primary Total Hip Replacement: A Registry-Based Cohort Study from the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man

BACKGROUND

Total hip replacement (THR) with a cemented polished taper-slip (PTS) femoral stem has excellent long-term results but is associated with a higher postoperative periprosthetic femoral fracture (PFF) risk compared with composite beam stems. This study aimed to identify risk factors associated with PFF revision following THR with PTS stems.

METHODS

In a retrospective cohort study, 299,019 primary THRs using PTS stems from the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR) were included, with a median follow-up of 5.2 years (interquartile range [IQR], 3.1 to 8.2 years). The adjusted hazard ratio (HR) of PFF revision was estimated for each variable using multivariable Cox survival regression analysis.

RESULTS

Of 299,019 THR cases, 1,055 underwent revision for PFF at a median time of 3.1 years (IQR, 1.0 to 6.1 years). The mean age (and standard deviation) was 72 ± 9.7 years, 64.3% (192,365 patients) were female, and 82.6% (247,126 patients) had an American Society of Anesthesiologists (ASA) class of 1 or 2. Variables associated with increased PFF were increasing age (HR, 1.02 per year), intraoperative fracture (HR, 2.57 [95% confidence interval (CI), 1.42 to 4.66]), ovaloid (HR, 1.96 [95% CI, 1.22 to 3.16]) and round cross-sectional shapes (HR, 9.58 [95% CI, 2.29 to 40.12]), increasing stem offset (HR, 1.07 per millimeter), increasing head size (HR, 1.04 per millimeter), THR performed from 2012 to 2016 (HR, 1.45 [95% CI, 1.18 to 1.78]), cobalt-chromium stem material (HR, 6.7 [95% CI, 3.0 to 15.4]), and cobalt-chromium stems with low-viscosity cement (HR, 22.88 [95% CI, 9.90 to 52.85]). Variables associated with a decreased risk of PFF revision were female sex (HR, 0.52 [95% CI, 0.45 to 0.59]), increasing stem length (HR, 0.97 per millimeter), and a ceramic-on-polyethylene bearing (HR, 0.55 [95% CI, 0.36 to 0.85]).

CONCLUSIONS

Increased risk of PFF revision was associated with PTS stems that are short, have high offset, are used with large femoral heads, are made of cobalt-chromium, or have ovaloid or round cross-sectional shapes. Large increases in PFF risk were associated with cobalt-chromium stems used with low-viscosity cement. Further study is required to confirm causation.

Structure-Altering Mutations of the SARS-CoV-2 Frame Shifting RNA Element

With the rapid rate of Covid-19 infections and deaths, treatments and cures besides hand washing, social distancing, masks, isolation, and quarantines are urgently needed. The treatments and vaccines rely on the basic biophysics of the complex viral apparatus. While proteins are serving as main drug and vaccine targets, therapeutic approaches targeting the 30,000 nucleotide RNA viral genome form important complementary approaches. Indeed, the high conservation of the viral genome, its close evolutionary relationship to other viruses, and the rise of gene editing and RNA-based vaccines all argue for a focus on the RNA agent itself. One of the key steps in the viral replication cycle inside host cells is the ribosomal frameshifting required for translation of overlapping open reading frames. The frameshifting element (FSE), one of three highly conserved regions of coronaviruses, includes an RNA pseudoknot considered essential for this ribosomal switching. In this work, we apply our graph-theory-based framework for representing RNA secondary structures, "RAG" (RNA-As Graphs), to alter key structural features of the FSE of the SARS-CoV-2 virus. Specifically, using RAG machinery of genetic algorithms for inverse folding adapted for RNA structures with pseudoknots, we computationally predict minimal mutations that destroy a structurally-important stem and/or the pseudoknot of the FSE, potentially dismantling the virus against translation of the polyproteins. Additionally, our microsecond molecular dynamics simulations of mutant structures indicate relatively stable secondary structures. These findings not only advance our computational design of RNAs containing pseudoknots; they pinpoint to key residues of the SARS-CoV-2 virus as targets for anti-viral drugs and gene editing approaches.

The evolution of white matter microstructural changes after mild traumatic brain injury: A longitudinal DTI and NODDI study

Neuroimaging biomarkers that can detect white matter (WM) pathology after mild traumatic brain injury (mTBI) and predict long-term outcome are needed to improve care and develop therapies. We used diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) to investigate WM microstructure cross-sectionally and longitudinally after mTBI and correlate these with neuropsychological performance. Cross-sectionally, early decreases of fractional anisotropy and increases of mean diffusivity corresponded to WM regions with elevated free water fraction on NODDI. This elevated free water was more extensive in the patient subgroup reporting more early postconcussive symptoms. The longer-term longitudinal WM changes consisted of declining neurite density on NODDI, suggesting axonal degeneration from diffuse axonal injury for which NODDI is more sensitive than DTI. Therefore, NODDI is a more sensitive and specific biomarker than DTI for WM microstructural changes due to mTBI that merits further study for mTBI diagnosis, prognosis, and treatment monitoring.

Mixed higher-order anisotropic flow and nonlinear response coefficients of charged particles in PbPb collisions at s NN = 2.76 and 5.02 TeV

Anisotropies in the initial energy density distribution of the quark-gluon plasma created in high energy heavy ion collisions lead to anisotropies in the azimuthal distributions of the final-state particles known as collective anisotropic flow. Fourier harmonic decomposition is used to quantify these anisotropies. The higher-order harmonics can be induced by the same order anisotropies (linear response) or by the combined influence of several lower order anisotropies (nonlinear response) in the initial state. The mixed higher-order anisotropic flow and nonlinear response coefficients of charged particles are measured as functions of transverse momentum and centrality in PbPb collisions at nucleon-nucleon center-of-mass energies s NN = 2.76 and 5.02 TeV with the CMS detector. The results are compared with viscous hydrodynamic calculations using several different initial conditions, as well as microscopic transport model calculations. None of the models provides a simultaneous description of the mixed higher-order flow harmonics and nonlinear response coefficients.

Not just studies, but fitness can also get you the intelligence and the grades!!

Objectives Physical fitness in children and adolescents determines their health status and predicts if they are prone to co-morbidities that may extend in adulthood. The initial literature on the benefits of being physically fit was limited to the musculoskeletal and cardio-respiratory systems. The recent trends have shown that physical fitness has an effect on the neurological system as well. Considering physical inactivity to be a problem in today's world and the growing evidences on physical fitness being related to cognition and academic performance, there is a need to explore more on these relationships. Thus, this study aims to find the correlation between physical fitness with academic performance and cognitive functions in adolescent urban school children. Hypothesis There is an association between physical fitness with academic performance and cognitive function. Methodology Three hundred and ninteen children were approached out of which 107 children consented for assessment. Their physical fitness was measured using the Progressive Aerobic Cardiovascular Endurance Run (PACER) test, the cognitive function was assessed using the Stroop test and the academic performance were taken from their final exam grades of 2019. Results A moderate positive correlation was found between physical fitness with cognitive function (r=0.528), with academic performance (r=0.545) and with self-reported physical activity per week (r=0.427). A fair negative correlation was found between physical fitness and Body Mass Index (BMI) (r=0.296). Conclusion This study confirms that physical fitness is positively associated with cognitive function, academic performance and self-reported physical activities and has a negative correlation with BMI.

THU0299 MYOCARDIAL INVOLVEMENT IN TAKAYASU ARTERITIS PATIENTS ASSESSED BY MAGNETIC RESONANCE IMAGING AND ITS RELATION WITH DISEASE ACTIVITY

Background:

Cardiac involvement in Takayasu arteritis(TA) is the major cause of morbidity and mortality. [1] Cardiovascular magnetic resonance (CMR) is an excellent modality for the assessment of myocardial involvement. Studies have shown subclinical myocardial scarring in 25-27% of patients.[2,3] There is no such study from India.

Objectives:

To evaluate the prevalence of myocardial involvement in TA, as detected by CMR and its correlation with disease activity score (ITAS 2010 and ITAS-A).

Methods:

Patients classified as Takayasu arteritis according to Sharma et al. criteria [4] were included after an informed consent. Demographic, clinical, laboratory data were documented in the predesigned proforma. CMR was done on a dedicated CMR machine. Disease activity was recorded by ITAS2010 and ITAS-A.[5] Ethical clearance has been obtained from the ethics committee of the institute (INT/IEC/2018/001538).

Results:

In the present study, 37 TA patients were included. Mean(±SD) age was 29 ±11 years. Female to male ratio was 3:1. The most frequent presenting symptom was upper limb claudication (49%), and vessel involved was left subclavian and descending thoracic aorta(75% each). Of the total cohort, 65% had hypertension, 35% had dyslipidemia and 19% had valvular involvement. Five patients (14%) had myocardial involvement as detected by CMR. Three (8%) patients had late gadolinium enhancement(LGE) on CMR suggestive of myocardial fibrosis. In the current study, both the CMR and echocardiography performed equally in detecting various valvular heart disease, whereas only CMR had detected subclinical myocardial fibrosis in two patients. Details of different risk factors and relation with disease activity provided in table 1.

Conclusion:

To the best of our knowledge, this is the largest cohort on CMR in TA. Prevalence of subclinical myocardial involvement in Indian patients was much less(8% vs 25-27%) compared to the previous studies. The higher percentage of LGE detected by the earlier studies may be a reflection of cumulative damage with increasing age, prolonged hypertension, and disease duration. Myocardial involvement trend towards early age of onset, less disease duration, lack of classical risk factors, and more with disease activity. Judicious use of CMR may help in detecting subclinical myocardial involvement.

AB0395 SYSTEMIC LUPUS ASSOCIATED MACROPHAGE ACTIVATION SYNDROME – A SINGLE CENTRE EXPERIENCE FROM INDIA

Background:

Macrophage activation syndrome (MAS) is a potentially fatal complication of systemic lupus erythematosus (SLE).(1) Overlapping clinical features of SLE activity with MA makes it a clinical diagnosis. There is limited data from developing countries like India.

Objectives:

To study the clinical features, treatment, and outcomes in SLE-MAS.

Methods:

This single-centre, retrospective study included patients fulfilling SLICC 2011 criteria for SLE, admitted from January 2017 to November 2019, and diagnosed as MAS by a team of attending physicians. Their demographic and clinical data, treatment, and outcomes were recorded. H score and SLEDAI were calculated. Patients were assessed for HLH classification criteria (2004) and preliminary diagnostic criteria for MAS in childhood SLE (cSLE).

Results:

Sixteen patients (median age – 26 years, 15 females) were included. Twelve patients (75%) had MAS as the initial presentation of SLE. The common clinical features were fever (100%) and cytopenias (100%). The mean duration of symptoms was 60 days. The most frequent biochemical abnormalities were high ferritin (>500 ng/ml, 100%) and elevated transaminases (100%, aspartate transaminase > alanine transaminase). Common complications were renal (43.8%), neurological (43.8%), and coagulopathy (43.8%). Seven and 16 patients fulfilled the HLH 2004 and cSLE – MAS preliminary criteria, respectively. The median H score was 222, giving a cumulative probability of 96%. All the patients received high-dose steroids. Cyclophosphamide pulse and cyclosporine were administered to 8 (50%) and 6 (37.5%) patients respectively. There were four (25%) in-hospital mortalities.

AB0570 MIXED CONNECTIVE TISSUE DISEASE: NOT THAT UNCOMMON, A SINGLE-CENTER EXPERIENCE FROM INDIA

Background:

Mixed connective tissue disease (MCTD) is considered to be uncommon; specifically there is sparse data on MCTD from developing countries like India.

Objectives:

This study examines the clinical and serological features of these patients in a single center in North-India.

Methods:

This was a retrospective single-center study of patients diagnosed as MCTD in last 20 years. The patients included fulfilled at least one of the diagnostic criteria namely Alarcón-Segovia, Kasukawa, and Kahns. Demographic details, clinical signs and symptoms, laboratory parameters, treatment and outcome were extracted from medical records and clinic files in a pre-designed proforma.

Results:

This study included 41 MCTD patients. There was a marked female preponderance (F: M=40:1), and mean age of disease onset and diagnosis was 33.8 ± 10.7 and 39.3 ± 10.2 years. 39 (92%) of the patients fulfilled both Kahn and Kasukawa criteria, while 31 (76%) fulfilled Alarcon-Segovia criteria. Initially patients had been (mis)diagnosed as rheumatoid arthritis, systemic lupus erythematosus (or UCTD) (in five patients each), overlap syndromes or myositis (in 4 patients). ANA was commonly high-titer and specked, U1RNP was positive in all. (Table 1) Other autoantibodies on immunoblot included SSA and Ro52 in half the patients. Raynaud’s was seen in three-fourth at presentation and all the patients over time. Digital gangrene and puffy fingers were seen in 8 (20%) and 18 (46%) patients. Other clinical features included arthritis in 33 (81%), sclerodactyly in 23 (56%) and proximal weakness in 20 patients (49%). Interstitial lung disease and pulmonary arterial hypertension were seen in 20 (57%) and 15 (44%) patients. All patients (except one) received prednisolone, and it was currently used in almost 90%. Intravenous cyclophosphamide was used in one-third, commonly for ILD.

OP0108 RANDOMIZED CONTROLLED TRIAL OF ORAL CORTICOSTEROIDS IN AXIAL SPONDYLOARTHROPATHY: MODIFIED COBRA REGIME

Background:

There is an unmet need of anti-inflammatory agents in AxSpA after NSAID failure. This is especially true for patients with persisting high disease activity and not having access to anti-TNFα. In this regard, corticosteroids may be helpful as a short-term measure. However, current guidelines recommend against oral corticosteroids citing insufficient evidence of efficacy.1. Also, there is an assumption that the dose required for benefit is much higher than RA, and thus untenable. It is unclear whether starting with a high dose followed by rapid taper would be effective (like the COBRA regime in RA)2.

Objectives:

To study the efficacy of the COBRA regime of oral corticosteroids in axial SpA over 24 weeks.

Methods:

This was a double blind placebo controlled randomized trial. Patients with active axial SpA (BASDAI ≥ 4) despite NSAIDs were randomized to either receive oral prednisolone or placebo as per COBRA regime, started on oral prednisolone at a dose of 60 mg, rapidly tapered weekly to reach a dose of 10 mg by 6 weeks and subsequently maintained on a low dose of 5 mg till 24 weeks. Primary end point was 50% improvement in BASDAI at week 24. Secondary end points were improvement in ASDAS and BASFI. Analysis was by intention-to-treat. Trial Registration# CTRI/2018/01/011342

Results:

This study enrolled 65 patients (62 males) who were randomized to corticosteroid (n=32) or placebo (n=33) with mean ± SD age 28.5 ± 8.4 years and BASDAI 5.4 ± 1.0. Primary end point was reached in 12 (37.5%) and 3 (9%) patients treated with steroids and placebo respectively (p=0.007). On repeated measures analysis by general linear model, there was a significant difference between the two-groups in BASDAI (p= 0.03) (Figure-1). Patients in the corticosteroid group had significant improvement in BASDAI, ESR, CRP, ASDAS ESR and ASDAS CRP at 24 weeks (Table-1). Clinically important improvement in ASDAS CRP was achieved by significantly higher number of patients in steroid group (17 (55%) vs 6 (18%), p= 0.002). Major improvement in ASDAS ESR and ASDAS CRP was also higher in the steroid group (Figure-2). At 24 weeks, patients in the steroid group had significant reduction in IL-6 levels compared to that in placebo group (p= 0.007, data for 41 patients). Patients in the steroid group had more weight gain and facial puffiness, however no serious adverse events were noted in both the groups.

Conclusion:

Oral prednisolone given by COBRA regime was associated with significant improvement in disease activity scores in axial SpA at 24 weeks. This extends and supports results from a previous short term study.3Thus, corticosteroids may be an option for patients not having access to biologics, atleast for the short-term.

Do GLP-1RAs and SGLT-2is reduce cardiovascular events in women with type 2 diabetes? A systematic review and meta-analysis

AIMS

The risk of cardiovascular disease is often underestimated in women. This leads to a delay in controlling the risk factors for cardiovascular disease and even delays in prescribing medications with cardiovascular benefit. Our aim was to explore if glucagon-like peptide-1 receptor agonist (GLP-1RA) or sodium-glucose cotransporter-2 inhibitor (SGLT-2i) medications would reduce cardiovascular events in women with type 2 diabetes when atherosclerotic cardiovascular disease (ASCVD) predominates.

MATERIALS AND METHODS

We searched for randomized trials comparing GLP-1RA or SGLT-2i to placebo in people with type 2 diabetes and had a primary outcome exploring major adverse cardiovascular events (MACE). Data concerning women were then extracted. A sensitivity and subgroup analyses were performed according to the class of diabetes medication.

RESULTS

A total of 9 trials (GLP-1RA in 6 trials and SGLT-2i in 3) were included. Of the 84,258 participants enrolled, 30,784 (37%) participants were women. Pooled results showed a statistically significant lower incidence of MACE favouring diabetes medications (GLP-1RA or SGLT-2i) compared to placebo (RR [95%CI]=0.87 [0.80, 0.94]). On restricting the analysis to GLP-1RA then to SGLT-2i, results remained significant with GLP-1RA but not SGLT-2i.

CONCLUSIONS

In women with type 2 diabetes who either have increased cardiovascular risk or established cardiovascular disease and ASCVD predominates, GLP-1RA significantly reduce the incidence of MACE while SGLT-2i result in a non-significant reduction. SGLT-2i may have comparable effect when examined in more studies. GLP-1RA and SGLT-2i should be considered without delay in women with type 2 diabetes and increased risk for cardiovascular disease.

Health resource utilization of labor induction versus expectant management

BACKGROUND

Although induction of labor of low-risk nulliparous women at 39 weeks reduces the risk of cesarean delivery compared with expectant management, concern regarding more frequent use of labor induction remains, given that this intervention historically has been thought to incur greater resource utilization.

OBJECTIVE

The objective of the study was to determine whether planned elective labor induction at 39 weeks among low-risk nulliparous women, compared with expectant management, was associated with differences in health care resource utilization from the time of randomization through 8 weeks postpartum.

STUDY DESIGN

This is a planned secondary analysis of a multicenter randomized trial in which low-risk nulliparous women were assigned to induction of labor at 39 weeks or expectant management. We assessed resource utilization after randomization in 3 time periods: antepartum, delivery admission, and discharge through 8 weeks postpartum.

RESULTS

Of 6096 women with data available, those in the induction of labor group (n = 3059) were significantly less likely in the antepartum period after randomization to have at least 1 ambulatory visit for routine prenatal care (32.4% vs 68.4%), unanticipated care (0.5% vs 2.6%), or urgent care (16.2% vs 44.3%), or at least 1 antepartum hospitalization (0.8% vs 2.2%, P < .001 for all). They also had fewer tests (eg, sonograms, blood tests) and treatments (eg, antibiotics, intravenous hydration) prior to delivery. During the delivery admission, women in the induction of labor group spent a longer time in labor and delivery (median, 0.83 vs 0.57 days), but both women (P = .002) and their neonates (P < .001) had shorter postpartum stays. Women and neonates in both groups had similar frequencies of postpartum urgent care and hospital readmissions (P > .05 for all).

CONCLUSION

Women randomized to induction of labor had longer durations in labor and delivery but significantly fewer antepartum visits, tests, and treatments and shorter maternal and neonatal hospital durations after delivery. These results demonstrate that the health outcome advantages associated with induction of labor are gained without incurring uniformly greater health care resource use.
