NOVEL NANO THERAPEUTIC MATERIALS FOR THE EFFECTIVE TREATMENT OF RHEUMATOID ARTHRITIS-RECENT INSIGHTS
Recent advances in science and technology and greatly modified the way we stumble on, deal with and prevent special diseases in all components of human lifestyles. Rheumatoid arthritis (RA) is the most not unusual complex multifactorial joint related autoimmune, chronic, severe systemic inflammatory ailment with unknown etiology completed with increased cardiovascular risks. It is regularly associated with critical synovial joint inflammation, autoantibody production, cartilage/bone tissue destruction, cardiovascular, pulmonary, skeletal disorders and massive inflammatory infiltration which might in the end motive extreme disability, huge complications, premature mortality and decreased life quality. Pro-inflammatory cytokines like IL-1, IL-6, IL-8 and IL-10 were dependable for the induction of inflammation in RA patients. It has a global occurrence of around 1% with the incidence among women being 2-3 times extra in men. Preclinical RA, genetic variables, and environmental factors have all been linked to the disease's etiology. Because there is no known cure for RA, the primary goal of treatment is to achieve the shortest possible illness duration and, if possible, rehabilitation. Current clinical remedies of RA display numerous drawbacks which include excessive doses, common administration, speedy metabolism, bad absorption, low responsiveness, higher cost and serious side consequences. These obstacles have inspired extremely good growth of the studies and to enhance those obstacles, nanoparticles that are able to encapsulating and protecting tablets from degradation earlier than they reach the target site in vivo, might also function drug delivery structures. Bioavailability and therapeutic bioactivity can be improved, and limited emphasis on damaged joints can be allowed. The current study provides a platform for different lipid nanoparticle methods for RA therapy, using the newly developing field of lipid nanoparticles to improve a targeted theranostic device for RA treatment. This review aims to present the most recent major application of lipid nanoparticles as a biocompatible and biodegradable transport device for improving RA concentration on over free drugs by presenting tissue-specific concentrated on of ligand-controlled drug release by modulating nanoparticle composition. Additionally, we also discuss the pivotal demanding situations to be addressed, as well as destiny views. Therefore, it is feasible to claim that nanoparticles will, within the near future, play a critical role in advanced treatment and affected person-particular cures for human diseases which include RA
Episodes of prolonged âtrance-like stateâ in an infant with hypothalamic hamartoma
Hypothalamic hamartoma (HH) is one of the most common causes of central precocious puberty (CPP) in first few years of life. It can present with either seizures or CPP, although both manifestations coexist in the majority of the children. Gelastic seizures (GS), or laughing spells, are usually the first type of seizures seen in patients with HH. Although a wide variety of seizure types are known to occur in children with HH, GS are most common and consistent seizure type. The clinical presentation of HH may vary with the size and position of the mass, although large tumours typically present with both CPP and seizures. Although CPP can be managed with medical therapy, seizures can be very difficult to treat, even with multiple antiepileptic drugs. Noninvasive gamma knife surgery has been used with some success for the treatment of refractory epilepsy. We present a case of HH with very early onset seizures and CPP. The patient had an atypical form of seizures described by the parents as a "trance-like state" in which the patient had prolonged episodes of unresponsiveness lasting for hours with normal feedings during the episodes. GS occurred late in the course and were refractory to various combinations of antiepileptic drugs. A brain magnetic resonance imaging showed a large sessile HH (>20 mm). Later in the course of the disease, the patient experienced cognitive and behavioural problems. The patient underwent gamma knife surgery at nearly 5 years of age and experienced a modest response in seizure frequency. This case highlights the presentation of HH as a previously unreported seizure morphology described as a prolonged "trance-like state.
Prevalence & perinatal outcome of GDM : a tertiary teaching hospital based study
Can we do something to improve outcomes of GDM?Much needs to be done to deal with epidemic of GDM in India as it affects both mother and fetus adversely.This study was aimed to find out the data pertaining to GDM.Using notional sampling frame 200 pregnant women were offered 75 gm oral glucose tolerance test between 24 to 28 weeks of gestation,irrespective of the fasting status as recommended by DIPSI.Patients having values â„140 mg/dl ,2 hrs after administration of 75 gm oral glucose were labelled as GDM.Whole cohort was followed during antenatal period and upto 7 days after delivery for fetomaternal outcome. Prevalence of GDM was 8% in our study. Statistically significant increased rates of gestational hypertension,chronic hypertension, preeclampsia,UTI,preterm delivery,rate of caesarean section and polyhydramnios were found in GDM patients.Statistically significant higher rates of metabolic complications,respiratory distress,admission to neonatal unit and macrosomia were found in neonates of GDM mothers.Hence there is a need for studying outcomes as well as cost effectiveness of different diagnostic criteria while simultaneously creating social awareness, training manpower, and sensitizing policymakers to make GDM testing and management mandatory during pregnancy at all levels
Secondary Scleral Fixated Intraocular Lens Implantation in Aphakia â Sutured vs Sutureless SFIOLâs
Purpose: To study and compare the safety and efficacy of two techniques of SFIOL implantation, i.e. sutured versus sutureless SFIOL. Methods: 80 aphakic eyes (due to complicated cataract surgeries in the past) were included in our study. Secondary SFIOL implantation was done in all the subjects. Patients were randomly divided into 2 groups using lottery method. Preoperative BCVA, slit lamp examination, fundus examination, macular OCT and IOP were noted for both the groups. In both the groups, SFIOL was implanted after doing anterior vitrectomy. Group A consisted of 40 patients who underwent SFIOL implantation (sutured) using 9-0 prolene suture whereas Group B consisted of 40 patients who underwent SFIOL implantation using Modified Yamane technique (sutureless). Results: Pre-operative BCVA of 26 patients (65%) in Group A and 22 patients (55%) in Group B was found to be less than 3/60. Post-operative BCVA at 6 months follow up was found to be in range of 6/24 to 6/18 in 28 patients (70%) in Group A and 24 patients(60%) in Group B. We found that the postoperative visual acuity improved in both the groups as compared to preoperative levels but comparison of post operative BCVA between the two groups was not significant. Conclusion: Results of both the techniques are comparable. Long-term data comparing the various techniques used to place SFIOLs will be crucial to identify optimal strategies for SFIOL implantation

The risk of tuberculosis in children after close exposure: a systematic review and individual-participant meta-analysis
BackgroundTens of millions of children are exposed to Mycobacterium tuberculosis globally every year; however, there are no contemporary estimates of the risk of developing tuberculosis in exposed children. The effectiveness of contact investigations and preventive therapy remains poorly understood.MethodsIn this systematic review and meta-analysis, we investigated the development of tuberculosis in children closely exposed to a tuberculosis case and followed for incident disease. We restricted our search to cohort studies published between Jan 1, 1998, and April 6, 2018, in MEDLINE, Web of Science, BIOSIS, and Embase electronic databases. Individual-participant data and a pre-specified list of variables were requested from authors of all eligible studies. These included characteristics of the exposed child, the index case, and environmental characteristics. To be eligible for inclusion in the final analysis, a dataset needed to include: (1) individuals below 19 years of age; (2) follow-up for tuberculosis for a minimum of 6 months; (3) individuals with household or close exposure to an individual with tuberculosis; (4) information on the age and sex of the child; and (5) start and end follow-up dates. Studies assessing incident tuberculosis but without dates or time of follow-up were excluded. Our analysis had two primary aims: (1) estimating the risk of developing tuberculosis by time-period of follow-up, demographics (age, region), and clinical attributes (HIV, tuberculosis infection status, previous tuberculosis); and (2) estimating the effectiveness of preventive therapy and BCG vaccination on the risk of developing tuberculosis. We estimated the odds of prevalent tuberculosis with mixed-effects logistic models and estimated adjusted hazard ratios (HRs) for incident tuberculosis with mixed-effects Poisson regression models. The effectiveness of preventive therapy against incident tuberculosis was estimated through propensity score matching. The study protocol is registered with PROSPERO (CRD42018087022).FindingsIn total, study groups from 46 cohort studies in 34 countries-29 (63%) prospective studies and 17 (37%) retrospective-agreed to share their data and were included in the final analysis. 137â647 tuberculosis-exposed children were evaluated at baseline and 130â512 children were followed for 429â538 person-years, during which 1299 prevalent and 999 incident tuberculosis cases were diagnosed. Children not receiving preventive therapy with a positive result for tuberculosis infection had significantly higher 2-year cumulative tuberculosis incidence than children with a negative result for tuberculosis infection, and this incidence was greatest among children below 5 years of age (19·0% [95% CI 8·4-37·4]). The effectiveness of preventive therapy was 63% (adjusted HR 0·37 [95% CI 0·30-0·47]) among all exposed children, and 91% (adjusted HR 0·09 [0·05-0·15]) among those with a positive result for tuberculosis infection. Among all children <5 years of age who developed tuberculosis, 83% were diagnosed within 90 days of the baseline visit.InterpretationThe risk of developing tuberculosis among exposed infants and young children is very high. Most cases occurred within weeks of contact investigation initiation and might not be preventable through prophylaxis. This suggests that alternative strategies for prevention are needed, such as earlier initiation of preventive therapy through rapid diagnosis of adult cases or community-wide screening approaches.FundingNational Institutes of Health

Charged-particle multiplicity fluctuations in PbâPb collisions at âsNN = 2.76 TeV
Measurements of event-by-event fluctuations of charged-particle multiplicities in PbâPb collisions at sNNââââ = 2.76 TeV using the ALICE detector at the CERN Large Hadron Collider (LHC) are presented in the pseudorapidity range |η|<0.8 and transverse momentum 0.2<pT<2.0 GeV/c. The amplitude of the fluctuations is expressed in terms of the variance normalized by the mean of the multiplicity distribution. The η and pT dependences of the fluctuations and their evolution with respect to collision centrality are investigated. The multiplicity fluctuations tend to decrease from peripheral to central collisions. The results are compared to those obtained from HIJING and AMPT Monte Carlo event generators as well as to experimental data at lower collision energies. Additionally, the measured multiplicity fluctuations are discussed in the context of the isothermal compressibility of the high-density strongly-interacting system formed in central PbâPb collisions
