III. SPIN-1/2 FERROMAGNETIC CHAIN A. Model, scattering states, and bound stateWe discuss the spin-1/2 ferromagnetic Heisenberg chain with L sites and periodic boundary conditions described by the Hamiltonian:

Motivated by the intriguing mode splittings in a magnetic field recently observed with inelastic neutron scattering in the spin ladder compound (C5H12N)2CuBr4 (BPCB), we investigate the nature of the spin ladder excitations using DMRG and analytical arguments. Starting from the fully frustrated ladder, for which we derive the low-energy spectrum, we show that bound states are generically present close to k = 0 in the dynamical structure factor of spin ladders above Hc1, and that they are characterized by a field-independent binding energy and an intensity that grows with H − Hc1. These predictions are shown to explain quantitatively the split modes observed in BPCB. arXiv:1912.01576v2 [cond-mat.str-el]

Background: Objective of the study was to evaluate the pattern of dyslipidaemia in newly diagnosed type 2 diabetes mellitus-2 (T2DM) patients and to understand the initial management options utilised by the treating physician.Methods: The real world, retrospective, observational recent trends in the patterns of dyslipidemia and management strategy in newly diagnosed patients of type 2 diabetes mellitus-2 (REMAP-2) study was conducted at various centers including hospitals, clinics, and health care institutes across India between Apr-2021 and Mar-2022. Clinicians at the respective center captured the data in REMAP-2 study data capture form. Dyslipidemia was considered as: total cholesterol >200 mg/dl, low density lipoprotein cholesterol (LDL-C) >100 mg/dl, high density lipoprotein cholesterol (HDL-C) <40 mg/dl, or triglyceride >150 mg/dl.Results: Of 9605 newly diagnosed T2DM patients with dyslipidemia, 68.94% (n=6622) had mixed dyslipidemia. The mean age was 53.8 years. Majority of the patients were males (63.3%), had family history of diabetes (52.5%), physical activity category of ‘not very active’ or ‘lightly active’ (79.33%), and were overweight or obese (58.9%). About 25.9% of the patients were smokers. Hypertension (72.33%) was the most common comorbidity followed by coronary artery disease (23.44%). The mean glycated hemoglobin (HbA1c) was 8.3%. The most commonly prescribed antidiabetic medication was metformin (87.71%), while lipid lowering therapy was atorvastatin (77.79%).Conclusions: This study on newly diagnosed T2DM patients with dyslipidemia found that majority of the patients had hypertriglyceridemia, family history of diabetes and were physically inactive. More than half of T2DM patients were either overweight or obese. More than 2/3rd of the patients had mixed dyslipidemia. Statins were prescribed to the majority of these patients and atorvastatin was the most commonly prescribed statin in Indian T2DM patients with dyslipidemia.

Background: The understanding of demographic patterns and the real-world management practices for patients with acute coronary syndrome (ACS) will facilitate optimizing the management strategies for ACS based on the patient’s clinical profile and the associated risk factors in Indian patients. Hence, this study determined the demographic details and the treatment patterns in Indian patients with ACS.Methods: The RECent trends in the pattern and lOng-term management stRategy of patients Diagnosed with acute coronary syndrome in India (RECORD ACS-2) study was a real-world, retrospective, cross-sectional, observational study conducted at various centres across India between 2021 and 2022. The study outcomes included the demographic profile and therapeutic management in patients with ACS.Results: A total of 9945 patients with a mean age of 59 years were included. The ACS was commonly observed in the age group of 41-70 years with highest incidence in the age group of 51-60 years. The ST-elevation myocardial infarction (STEMI) was most common (53.2%) presentation. Hypertension (37.2%) and dyslipidemia (29.3%) followed by diabetes (21.3%) were the most common comorbidities. Single vessel disease was the most common angiographic feature (58%). Percutaneous coronary intervention was the most preferred management strategy (57%). Ticagrelor was the most preferred loading (68.3%) as well as maintenance (71.2%) P2Y12 inhibitor in ACS patients. Most of the patients (81.8%) had received high intensity statin therapy for the secondary prevention of the disease.Conclusions: The prevalence of ACS was high between 51-60 years of age, more so in males, smokers, and physically less active patients. Associated comorbidities were hypertension, dyslipidemia and diabetes. Incidence of STEMI was high, and more than half of the patients underwent PCI. Ticagrelor was the most preferred P2Y12 inhibitor in ACS patients for loading as well as maintenance therapy.
