Magnetization Dynamics in Quasiperiodic Magnonic Crystals.

Quasiperiodic magnonic crystals, in contrast to their periodic counterparts, lack strict periodicity which gives rise to complex and localised spin wave spectra characterized by numerous band gaps and fractal features. Despite their intrinsic structural complexity, quasiperiodic nature of these magnonic crystals enables better tunability of spin wave spectra over their periodic counterparts and therefore holds promise for the applications in reprogrammable magnonic devices. In this article, we provide an overview of magnetization reversal and precessional magnetization dynamics studied so far in various quasiperiodic magnonic crystals, illustrating how their quasiperiodic nature gives rise to tailored band structure, enabling unparalleled control over spin waves. The review is concluded by highlighting the possible potential applications of these quasiperiodic magnonic crystals, exploring potential avenues for future exploration followed by a brief summary.

Distribution of triglyceride-rich lipoproteins and their remnants and their contribution to cardiovascular risk in the Mexican population.

BACKGROUND AND AIMS: In recent years, scientific interest in triglyceride-rich lipoproteins (TRL) and remnant cholesterol has increased, focusing on the evidence that these lipoproteins are a causal factor for developing atherosclerotic cardiovascular disease (ASCVD). Furthermore, a high remnant concentration (>38 mg/dL) has been associated with several non-cardiovascular risks. We aimed in this study to describe the percentile distribution of remnant cholesterol. Additionally, we evaluated the association between remnant cholesterol plasma concentration and epidemiologically relevant cardio-metabolic outcomes such as hypertension, type 2 diabetes (T2D), and ASCVD. METHODS: We analyzed data from 9,591 adults from the National Survey of Health and Nutrition (ENSANUT) 2018 with fasting blood samples and complete medical history questionnaires. We built multivariate models to evaluate the association between chronic diseases and blood remnant concentration. To compare our 2018-sub-sample against a population reference, we used the NHANES (2005-2014) publicly available datasets by ethnicity. RESULTS: Remnants were independently associated with cardiovascular risk, diabetes, hypertension, obesity, and metabolic syndrome. For all outcomes, the blood remnant concentration was a stronger predictor than LDL. At all deciles, the blood remnant concentration was higher in ENSANUT-2018. CONCLUSIONS: A remnant blood concentration above 38 mg/dL was highly prevalent among Mexicans. Remnants were significantly associated with a higher risk of diabetes, hypertension, obesity, and cardiovascular risk. This association occurred independently of other lipid markers.

Blood lead levels in pregnant women and their newborn infants at an Indian teaching hospital.

Background and Aim: With the growth of the world's economy and industrialization, lead (Pb) contamination in the environment has become a major issue on a global scale. Lead is typically linked to unfavorable pregnancy outcomes such as stillbirth, low birth weight preterm, and spontaneous abortion. In this study, we evaluated the blood lead levels of pregnant women and their birth outcomes attending an Indian tertiary care teaching hospital, those who were not exposed to any lead-associated industry or shops. Methods: A descriptive study was undertaken to evaluate blood lead estimation in pregnant women and umbilical blood lead levels in a community hospital. Blood samples from 104 mothers during the 1st trimester, 90 mothers during 3rd trimester, and from the umbilical cord were collected. Self-administered questionnaires were used to collect information on demographics, medical history, and concerns linked to pregnancy. Following acid digestion, the levels of lead in whole blood were determined by an atomic absorption spectrometer. The DNA damage in high blood lead-concentrated pregnant women was evaluated by comet assay methods. Results: Among 194 blood samples of pregnant women, 31 (15.98%) samples revealed ≥5 µg/dL blood lead levels. High lead concentration (≥5 µg/dL) in 1st trimester pregnant women, end of 3rd trimester and cord blood were detected 20.19%, 11.11% and 1.11% respectively. The mean blood lead levels in 1st trimester, 3rd trimester, and cord blood were 3.88 ± 3.19, 2.66 ± 1.82, and 1.53 ± 1.06 mg/dL, respectively. The blood lead concentrations were significantly higher in the 1st trimester of pregnancy than in the 3rd trimester of pregnancy (P < 0.0017). A positive correlation between maternal and infant blood lead levels was revealed (P < 0.0001). When the comet assay was used to assess the genotoxic consequences of elevated blood lead levels during pregnancy, higher amounts of DNA damage were found in the samples (P < 0.01). Conclusion: In this descriptive study, there was a significant amount of lead transferred from mother to baby through the placenta. All mothers were not exposed to lead-associated industry and most were housewives. This article may be viewed as an eye-opener for understanding the blood lead concentration during pregnancy to avoid abnormal birth outcomes. To minimize exposure to environmental lead, all possible measures should be undertaken.

Tunability of spin-wave spectra in a 2D triangular shaped magnonic fractals.

Reprogramming the structure of the magnonic bands during their operation is important for controlling spin waves in magnonic devices. Here, we report the tunability of the spin-wave spectra for a triangular shaped deterministic magnonic fractal, which is known as Sierpinski triangle by solving the Landau-Lifshitz-Gilbert equation using a micromagnetic simulations. The spin-wave dynamics change significantly with the variation of iteration number. A wide frequency gap is observed for a structure with an iteration number exceeding some value and a plenty of mini-frequency bandgaps at structures with high iteration number. The frequency gap could be controlled by varying the strength of the magnetic field. A sixfold symmetry in the frequency gap is observed with the variation of the azimuthal angle of the external magnetic field. The spatial distributions of the spin-wave modes allow to identify the bands surrounding the gap. The observations are important for the application of magnetic fractals as a reconfigurable aperiodic magnonic crystals.

Can we evidence-base injury prevention and management in women's football? A scoping review.

This review aimed, as part of a larger FIFA project aiming to steer women's football research, to scope literature on any level of competitive football for women, to understand the current quantity of research on women's football injuries. The study reviewed all injury-related papers scoped by a recent scoping review mapping all published women's football research with an updated search performed on 23 February 2021. Eligibility criteria assessment followed the recent scoping review with injury-specific research focus. A total of 497 studies were scoped. Most studies contained an epidemiological (N = 226; 45%) or risk factors assessment (N = 105; 21%). Less assessed areas included financial burden (N = 1; <1%) and injury awareness (N = 5; 1%). 159 studies (32%) assessed injuries of the whole body. The most common single location assessed in the literature was the knee (N = 134, 27%), followed by head/face (N =108, 22%). These numbers were, however, substantially lowered, when subdivided by playing level and age-group. The volume of research focuses especially on descriptive research and specific body locations (head/face and knee). Although information can be taken from studies in other sports, more football-specific studies to support management and prevention of injuries are warranted.

A Study of Autologous Non-Cultured Epidermal Suspension (NCES) Transplant in Patients with Stable Vitiligo without the Use of NB-UVB.

Introduction:Vitiligo is a common form of localized depigmentation and an important public health problem which affects around one percent of the global population and about two percent of the population in India. The present study aimed to document the results and side effects of non-cultured melanocyte transplant in patients with stable vitiligo without post-procedure use of NB UVB. Methods:The present study was a prospective interventional study conducted among patients with stable vitiligo who were attending the outpatient department (OPD) of dermatology of a tertiary center of Delhi. Patients with stable vitiligo aged >10 years who gave their consent for non-cultured epidermal suspension (NCES) were included in the study. Autologous skin graft of size 0.2 mm was taken from the donor site and a melanocyte cell suspension was prepared using standardized procedure, which was later transplanted to the recipient area. All patients were asked to come for follow-up at the OPD after seven days, 15 days, one month, followed by every month till six months post-transplantation, and repigmentation was assessed visually by both graph paper and photography. Data was analyzed using SPSS vs. 21. Results:In our study, the majority of patients had vitiligo vulgaris (27 subjects with 47 patches). A total number of 59 patches were transplanted, of which 38 (64.4%) achieved excellent repigmentation, 28.8% good repigmentation, 3.4% fair repigmentation and 3.39% poor repigmentation. A total of 1302.5 cm² of the depigmented area was operated by NCES and the repigmentation of 874.5 cm2 (67.14%) was achieved by six months. Conclusion:The present study found that the majority of patients (93%) with vitiligo achieved excellent or good repigmentation after NCES and the rate of complication was very low.

Quantitative systems pharmacology modeling sheds light into the dose response relationship of a trispecific T cell engager in multiple myeloma.

In relapsed and refractory multiple myeloma (RRMM), there are few treatment options once patients progress from the established standard of care. Several bispecific T-cell engagers (TCE) are in clinical development for multiple myeloma (MM), designed to promote T-cell activation and tumor killing by binding a T-cell receptor and a myeloma target. In this study we employ both computational and experimental tools to investigate how a novel trispecific TCE improves activation, proliferation, and cytolytic activity of T-cells against MM cells. In addition to binding CD3 on T-cells and CD38 on tumor cells, the trispecific binds CD28, which serves as both co-stimulation for T-cell activation and an additional tumor target. We have established a robust rule-based quantitative systems pharmacology (QSP) model trained against T-cell activation, cytotoxicity, and cytokine data, and used it to gain insight into the complex dose response of this drug. We predict that CD3-CD28-CD38 killing capacity increases rapidly in low dose levels, and with higher doses, killing plateaus rather than following the bell-shaped curve typical of bispecific TCEs. We further predict that dose-response curves are driven by the ability of tumor cells to form synapses with activated T-cells. When competition between cells limits tumor engagement with active T-cells, response to therapy may be diminished. We finally suggest a metric related to drug efficacy in our analysis-"effective" receptor occupancy, or the proportion of receptors engaged in synapses. Overall, this study predicts that the CD28 arm on the trispecific antibody improves efficacy, and identifies metrics to inform potency of novel TCEs.

Urinary levels of energy metabolism hormones in association with the proportional intake of maternal milk and weight gain in very preterm neonates.

BACKGROUND: This study prospectively investigated the levels of energy metabolism hormones in very preterm neonates to identify their change over time and association with intake of maternal milk as well as weight gain velocity. METHODS: We measured and compared the leptin, adiponectin, ghrelin, and insulin-like growth factor I (IGF-1) levels in the urine of 70 very preterm neonates, before the initiation of any enteral feeding (baseline level) and twice within 14 days on full enteral feeding (FEF). Regression models identified the role of intake of maternal milk on the levels of the tested energy metabolism hormones in the enteral-fed infants. We also analyzed the adequacy of the weight gain velocity defined by the fetal-infant growth reference (FIGR). Additionally, we collected and analyzed the infants' clinical and feeding characteristics during the birth hospitalization. RESULTS: The preterm infants' baseline levels of the energy metabolism hormones significantly predicted their increase at the end of two weeks of observation on FEF. The leptin level was associated with increased intake of maternal milk, whereas the feeding volume was associated with increased ghrelin and IGF-1, and decreased leptin and adiponectin. Infants with comparable FIGR had higher leptin levels than those with inadequate weight gain velocity. CONCLUSION: Early postnatal levels of leptin, adiponectin, ghrelin, and IGF-1 predicted the increase of these hormones in the fully enteral fed very preterm neonates. Moreover, greater intake of maternal milk by the study infants contributed to an increased leptin-associated weight gain velocity.

Skin needling with 100% trichloroacetic acid vs. needling with bleomycin in the treatment of recalcitrant cutaneous warts.

The treatment of warts has always been a challenging prospect for dermatologists. In some cases, these warts can become resistant or recalcitrant to treatment. Although a plethora of therapeutic and destructive options is available for wart management, to date no treatment has been found to be completely effective because none of the agents induce specific antiviral immunity. We conducted a study to evaluate the efficacy and safety of skin needling with topical 100% trichloroacetic acid (TCA) against the same type of skin needling with bleomycin in patients with recalcitrant cutaneous warts. In total, 33 (63.5%) patients in the TCA group and 35 (81.4%) in the bleomycin group had complete clearance of all the warts, which was not statistically significant (P = 0.13). There was also no statistically significant difference between the treated and untreated warts in the bleomycin group, whereas in the TCA group there was a significantly higher response rate in the treated warts. The most common adverse event (AE) in both groups was transient procedure site pain. We found that the use of needling plus TCA leads to a faster resolution of warts compared with needling plus bleomycin, with a comparable safety profile. Additionally, we found that TCA is superior to bleomycin for management of multiple warts. However, needling with either TCA or bleomycin has excellent and fairly comparable efficacy, and these methods should be used for the management of multiple or recalcitrant warts, as they have minimal AEs and recurrence rates.

Treatment outcomes among patients admitted to hospital with antiretroviral and/or antituberculosis drug-induced liver injury.

BACKGROUND: South Africa (SA) has among the highest rates of HIV and tuberculosis (TB) in the world. Antituberculosis and antiretroviral treatment (ART) can cause drug-induced liver injury (DILI), consequences of which are disease relapse, treatment failure and drug resistance. OBJECTIVES: To: (i) determine the demographics of patients with DILI and the proportion of patients on antituberculosis drugs v. antiretroviral therapy or both; (ii) determine the median time to DILI after starting medication, and patterns of clinical presentation; (iii) determine the numbers of patients successfully re-challenged to initial therapy as inpatients; and (iv) determine the in-hospital mortality rate and predictors of all-cause mortality. METHODS: This was a retrospective record review of adult patients with DILI admitted to a tertiary hospital in Johannesburg, SA, between October 2015 and February 2017. Data on drug history, biochemical investigations and relevant imaging were collected. RESULTS: The total sample was 129 records: 79 (61.2%) were males, 46 (35.7%) had TB DILI, 29 (22.5%) had ART DILI, and 54 (41.9%) had mixed TB/ART DILI. Only 7.4% (2/27) of those with ART DILI and 30.6% (11/36) with TB DILI were re-challenged to their original regimen by discharge. Patients were followed from admission until the earlier of death (10 with TB DILI, 2 with ART DILI and 9 with mixed DILI) or discharge (after a median (interquartile range) of 14.0 (9 - 23) days). In adjusted analysis, severe DILI at admission predicted all-cause mortality (adjusted hazard ratio 8.58; 95% confidence interval 1.13 - 65.4). CONCLUSIONS: This study is one of only a few analyses of hospitalised patients with DILI in SA. Among those with severe DILI, outcomes are poor, the majority cannot tolerate standard regimens, and mortality is high.

Ultrasound-mediated disruption of the blood tumor barrier for improved therapeutic delivery.

The blood-brain barrier (BBB) is a major anatomical and physiological barrier limiting the passage of drugs into brain. Central nervous system tumors can impair the BBB by changing the tumor microenvironment leading to the formation of a leaky barrier, known as the blood-tumor barrier (BTB). Despite the change in integrity, the BTB remains effective in preventing delivery of chemotherapy into brain tumors. Focused ultrasound is a unique noninvasive technique that can transiently disrupt the BBB and increase accumulation of drugs within targeted areas of the brain. Herein, we summarize the current understanding of different types of targeted ultrasound mediated BBB/BTB disruption techniques. We also discuss influence of the tumor microenvironment on BBB opening, as well as the role of immunological response following disruption. Lastly, we highlight the gaps between evaluation of the parameters governing opening of the BBB/BTB. A deeper understanding of physical opening of the BBB/BTB and the biological effects following disruption can potentially enhance treatment strategies for patients with brain tumors.

Nail Changes Caused by Chemotherapy among Cancer Patients: A Cross-Sectional Study of Northwest Rajasthan.

BACKGROUND: The nail changes caused by chemotherapy in cancer patients are difficult to assess and often overlooked by clinician. The present study was undertaken to study nail changes caused by various chemotherapeutic agents and various drug protocols most commonly associated with them. MATERIALS AND METHOD: Five hundred patients with malignancies receiving chemotherapy in the oncology ward and skin outpatient department were screened in this cross-sectional observational study from November 2018 to October 2019. RESULTS: Nail changes due to chemotherapy were observed in 37.6% patients. The most common condition observed was melanonychia (84.04%), followed by half and half nails (6.91%), erythronychia (5.31%), longitudinal grooves (2.12%), leukonychia (2.12%), Mees' lines (1.59%), Beau's lines (0.53%), pitting (0.53%), and subungual hyperkeratosis (0.53%). The usual protocol to cause melanonychia was platinum analogues + taxanes based combinations, half and half nails by platinum analogues + taxanes + 5 fluorouracil (5FU) based polypharmacy, and erythronychia by cisplatin-based adjuvants. CONCLUSION: The knowledge of the nail changes caused by chemotherapy will help in counseling of already worried patients with malignancy. It will also improve patient compliance and enrich the clinicians' knowledge pertaining to chemotherapy-induced nail changes.

Over-under cartilage tympanoplasty: technique, results and a call for improved reporting.

OBJECTIVE: This study aimed to describe the microscopic over-under cartilage tympanoplasty technique, provide hearing results and detail clinically significant complications. METHOD: This was a retrospective case series chart review study of over-under cartilage tympanoplasty procedures performed by the senior author between January 2015 and January 2019 at three tertiary care centres. Cases were excluded for previous or intra-operative cholesteatoma, if a mastoidectomy was performed during the procedure or if ossiculoplasty was performed. Hearing results and complications were obtained. RESULTS: Sixty-eight tympanoplasty procedures met the inclusion criteria. The median age was 13 years (range, 3-71 years). The mean improvement in pure tone average was 6 dB (95 per cent confidence interval 4-9 dB; p < 0.0001). The overall perforation closure rate was 97 per cent (n = 66). Revision surgery was recommended for a total of 6 cases (9 per cent) including 2 post-operative perforations, 1 case of middle-ear cholesteatoma and 3 cases of external auditory canal scarring. CONCLUSION: Over-under cartilage tympanoplasty is effective at improving clinically meaningful hearing with a low rate of post-operative complications.

Profile of osteoarticular tuberculosis in children.

OBJECTIVE: To determine clinical profile of osteoarticular tuberculosis (TB) in children. METHODS: Cross-sectional analysis from 2007 to 2013. All patients diagnosed with bone TB, spinal TB or TB abscesses were included. RESULTS: Out of 1318 children with TB, 39 (2.96%) had osteoarticular TB, of which 16 (42%) had osteomyelitis, 8 (20.5%) had spinal involvement, 7 (17.9%) had TB synovitis, 2 (5.1%) had psoas abscess and 6 (15.4%) had abscesses. The mean age of presentation was 7.1 ± 3.5 years (range 2-14 years). Of the 33 cases in which a culture was done, 25 (64%) showed a positive culture. Drug sensitivity tests were done in 21 patients of which 10 (47.6%) tested were drug resistant, of which 4 (36.4%) were multidrug resistant (MDR), 2 (18.2%) were extensively drug resistant (XDR), 3 were pre-XDR (27.3%) and 1 was polyresistant (9.1%). Nine (23.1%) patients had TB in the past with a treatment duration of 8.3 ± 5.3 months. Contact with a TB patient had occurred in 10 (25.6%) cases. Associated pulmonary TB were seen in 6 (15.39%) and TB meningitis were seen in 1 (2.6%) patients. Surgical intervention was needed in 11 (28.2%) patients of which 5 (45.5%) underwent curettage, drainage was done in 1 (9.1%), arthrotomy in 4 (36.4%) and spinal surgery in 1 (9.1%) patient. CONCLUSION: Drug resistant osteoarticular TB is an emerging problem in children.

Hepatocellular carcinoma tumour burden score to stratify prognosis after resection.

BACKGROUND: Although the Barcelona Clinic Liver Cancer (BCLC) staging system has been largely adopted in clinical practice, recent studies have emphasized the need for further refinement and subclassification of this system. METHODS: Patients who underwent hepatectomy with curative intent for BCLC-0, -A or -B hepatocellular carcinoma (HCC) between 2000 and 2017 were identified using a multi-institutional database. The tumour burden score (TBS) was calculated, and overall survival (OS) was examined in relation to TBS and BCLC stage. RESULTS: Among 1053 patients, 63 (6·0 per cent) had BCLC-0, 826 (78·4 per cent) BCLC-A and 164 (15·6 per cent) had BCLC-B HCC. OS worsened incrementally with higher TBS (5-year OS 77·9, 61 and 39 per cent for low, medium and high TBS respectively; P < 0·001). No differences in OS were noted among patients with similar TBS, irrespective of BCLC stage (61·6 versus 58·9 per cent for BCLC-A/medium TBS versus BCLC-B/medium TBS, P = 0·930; 45 versus 13 per cent for BCLC-A/high TBS versus BCLC-B/high TBS, P = 0·175). Patients with BCLC-B HCC and a medium TBS had better OS than those with BCLC-A disease and a high TBS (58·9 versus 45 per cent; P = 0·005). On multivariable analysis, TBS remained associated with OS among patients with BCLC-A (medium TBS: hazard ratio (HR) 2·07, 95 per cent c.i. 1·42 to 3·02, P < 0·001; high TBS: HR 4·05, 2·40 to 6·82, P < 0·001) and BCLC-B (high TBS: HR 3·85, 2·03 to 7·30; P < 0·001) HCC. TBS could also stratify prognosis among patients in an external validation cohort (5-year OS 79, 51·2 and 28 per cent for low, medium and high TBS respectively; P = 0·010). CONCLUSION: The prognosis of patients with HCC varied according to the BCLC stage but was largely dependent on the TBS.

ANTECEDENTES: Aunque el sistema de estadificación del Barcelona Clinic Liver Cancer (BCLC) ha sido adoptado en gran medida en la práctica clínica, estudios recientes han enfatizado la necesidad de un mayor refinamiento y subclasificación del sistema BCLC. MÉTODOS: Los pacientes con carcinoma hepatocelular (hepatocellular cancer, HCC) BCLC-0, A y B que se sometieron a una hepatectomía con intención curativa entre 2000 y 2017 fueron identificados utilizando una base de datos multi-institucional. Se calculó la puntuación de carga tumoral (tumour burden score, TBS) y se examinó la supervivencia global (overall survival, OS) en relación con la TBS y los estadios BCLC. RESULTADOS: En la serie de 1.053 pacientes, 63 (6%) tenían HCC BCLC-0, 826 (78,4%) HCC BCLC-A y 164 (15,6%) HCC BCLC-B. La OS disminuyó de forma incremental en función de la mayor TBS (OS a 5 años; TBS baja: 77,9% versus TBS media: 61% versus TBS alta: 39%, P < 0,001). No se observaron diferencias en la OS entre pacientes con una puntuación TBS similar, independientemente del estadio BCLC (BCLC-A/TBS media: 61,6% versus BCLC-B/TBS media: 58,9%, P = 0,93; BCLC-A/TBS alta: 45,1% versus BCLC-B/TBS alta: 12,8%, P = 0,175). Los pacientes con BCLC-B/TBS media tuvieron una mejor OS que los pacientes con BCLC-A/TBS alta (58,9% versus 45,1%, P = 0,005). En el análisis multivariable, la TBS se mantuvo asociada a la OS en el caso de BCLC-A (TBS media: cociente de riesgos instantáneos, hazard ratio, HR = 2,07, i.c. del 95%: 1,42-3,02, P < 0,001; TBS alta: HR = 4,05, i.c. del 95%: 2,40-6,82, P < 0,001) y BCLC-B pacientes (TBS alta: HR = 3,85, i.c. del 95%: 2,03-7,30, P < 0,001). La TBS también pudo estratificar el pronóstico entre pacientes en una cohorte de validación externa (OS a 5 años; TBS baja: 78,7% versus TBS media: 51,2% versus TBS alta: 27,6%, P = 0,01). CONCLUSIÓN: El pronóstico de los pacientes con HCC varió según el estadio BCLC, pero dependió en gran medida de la TBS.

The combination of insulin resistance and visceral adipose tissue estimation improves the performance of metabolic syndrome as a predictor of type 2 diabetes.

AIMS: To assess the performance of metabolic syndrome as a predictor of type 2 diabetes in a model that also includes both a measure of insulin resistance and a metabolic score for visceral fat, and to propose a novel metabolic syndrome definition. METHODS: In a prospective Metabolic Syndrome Cohort (n=6143), we evaluated improvements in type 2 diabetes risk prediction using International Diabetes Federation-defined and Adult Treatment Panel III-defined metabolic syndrome, after inclusion in the model of updated homeostatic model assessment of insulin resistance and a metabolic score for visceral fat. We also developed a modified metabolic syndrome construct, 'MS-METS', which used the metabolic score for visceral fat instead of waist circumference to evaluate improved predictive performance for risk of developing type 2 diabetes. RESULTS: Participants who had metabolic syndrome as defined by both the Adult Treatment Panel III and the International Diabetes Federation criteria had a higher risk of type 2 diabetes compared to participants who did not meet these criteria. Addition of updated homeostatic model assessment of insulin resistance and metabolic score for visceral fat to both metabolic syndrome definitions increased predictive performance for type 2 diabetes risk. Homeostatic model assessment of insulin resistance was the only additional predictor of type 2 diabetes in participants without metabolic syndrome. Conversely, in participants with metabolic syndrome, the use of the metabolic score for visceral fat was the stronger added predictor for type 2 diabetes. When evaluating participants using the MS-METS definition we observed the largest improvement in predictive ability for type 2 diabetes risk and a significant reduction in risk overestimation compared to evaluation using metabolic syndrome defined according to the International Diabetes Federation and Adult Treatment Panel III criteria alone. CONCLUSION: Inclusion of updated homeostatic model assessment of insulin resistance and metabolic score for visceral fat increases performance of metabolic syndrome in prediction of type 2 diabetes. Assessment of insulin resistance could be more useful than conventional metabolic syndrome and assessment of visceral adipose tissue could be more useful in people with metabolic syndrome. Metabolic syndrome as defined using our modified MS-METS construct improved the accuracy of type 2 diabetes prediction.

Comparison of Efficacy of Two Different Concentrations of Intralesional Amphotericin B in the Treatment of Cutaneous Leishmaniasis; A Randomized Controlled Trial.

INTRODUCTION: Cutaneous leishmaniasis is a vector borne disease caused by Leishmania major and Leishmania tropica. Bikaner is an endemic pocket for cutaneous leishmaniasis caused by Leishmania tropica. MATERIALS AND METHODS: A prospective study was done to evaluate the efficacy of different concentrations of intralesional amphotericin B as a treatment modality for cutaneous leishmaniasis in Bikaner, Rajasthan, India from January 2016 to June 2017. Fifty patients were randomized into two groups, A and B. Twenty-five patients from group A, received intralesionl amphotericin B (2.5 mg/ml) 0.5 ml/cm2, weekly for 8 weeks. Another group of 25 patients were treated by intralesional amphotericin B (5.0 mg/ml) weekly for same period. The cases were followed-up for response, side effects, and recurrence of disease. RESULTS: The results at the end of 8 weeks, showed complete response in 18 (72%) patients, partial response in 5 (20%) and 2 (8%) patients were non responders in group A. In group B, complete response was observed in 14 (56%), partial response in 7 (28%) patients and 4 (16%) patients did not show response. The difference was statistically insignificant (P > 0.05). No side effects were observed in both groups. CONCLUSION: The difference between the efficacy of 5 mg/ml and 2.5 mg/ml concentrations of Amphotericin B injections was found to be statistically insignificant. So, weekly injections of amphotericin B looks promising, however, larger sample size is required to assess the efficacy of both concentrations in the treatment of cutaneous leishmaniasis.
