Impact of LULC changes on small watershed morphometry and delineation of sustainable conservation strategies for degraded transboundary rivers.

Small streams in the large river basins are disappearing, and there is no update on their historical and current morphometric status. Field inventory and visual inspections quantified the impact of land use and land cover (LULC) change on the reference year morphometry (1970-1977) of seven watersheds and fifty-six subwatersheds, using drone imagery and Global Positioning System-based ground control points to refine the reference map and generate the current map (2021-2024). The decreasing stream number (Nu), stream length (Lu), and drainage density (Dd) (1) explained the mechanism of disappearing and shrinking large rivers; (2) classified seven watersheds and fifty-six subwatersheds into near threatened (NT), vulnerable (VU), endangered (EN), critically endangered (CR), and extinct (EX) categories; and (3) emphasized rejuvenation of 9,84,068 km of lost streams to restore Dd ≥ 2 km/km in the Ganga River basin (GRB).

Mechanism of Excited-State Dissociation of Ni-C and Ni-Br Bonds in (bpy)Ni(alkyl)(Br) Complexes.

NiRX (R = aryl, alkyl; X = halogen) complexes containing bipyridine (bpy)-type ligands play a crucial role in metallaphotoredox-catalyzed cross-coupling reactions. Despite the excited-state dissociation of Ni-C and Ni-halide bonds in the (bpy)Ni(aryl)(halide) complex being well understood, the corresponding (bpy)Ni(alkyl)(halide) complex remains largely unexplored. Experimentally, it is challenging due to its instability, making isolation and characterization difficult and necessitating computational investigations.

A Comprehensive Multireference Study of Excited-State Ni-Br Bond Homolysis in (dtbbpy)Ni(aryl)(Br).

The mechanism of visible light-driven Ni-C(aryl) bond homolysis in (2,2'-bipyridine)Ni(aryl)(halide) complexes, which play a crucial role in metallaphotoredox catalysis for cross-coupling reactions, has been well studied. Differently, the theoretical understanding of Ni-halide bond homolysis remains limited. In this study, we introduce a novel electronic structural framework to elucidate the mechanisms underlying photoinduced Ni-Br bond rupture in the (dtbbpy)Ni(aryl)(Br) complex.

Observational study protocol for an arrhythmia notification feature.

Introduction: Screening for atrial fibrillation (AF) in the general population may help identify individuals at risk, enabling further assessment of risk factors and institution of appropriate treatment. Algorithms deployed on wearable technologies such as smartwatches and fitness bands may be trained to screen for such arrhythmias. However, their performance needs to be assessed for safety and accuracy prior to wide-scale implementation.

Pragmatic Trial of Messaging to Providers About Treatment of Hyperlipidemia (PROMPT-LIPID): A Randomized Clinical Trial.

Background: Lipid-lowering therapy (LLT) is underutilized for very high-risk atherosclerotic cardiovascular disease. PROMPT-LIPID (PRagmatic Trial of Messaging to Providers about Treatment of HyperLIPIDemia) sought to determine whether electronic health record (EHR) alerts improve 90-day LLT intensification in patients with very high-risk atherosclerotic cardiovascular disease.

Methods: PROMPT-LIPID was a pragmatic trial in which cardiovascular and internal medicine clinicians within Yale New Haven Health (New Haven, CT) were cluster-randomized to receive an EHR alert with individualized LLT recommendations or no alert for outpatients with very high-risk atherosclerotic cardiovascular disease and LDL-C (low-density lipoprotein cholesterol), ≥70 mg/dL.

COVID-19-Associated Acute Kidney Injury and Longitudinal Kidney Outcomes.

Importance: COVID-19 infection is associated with a high incidence of acute kidney injury (AKI). Although rapid kidney function decline has been reported in the first few months after COVID-19-associated AKI (COVID-AKI), the longer-term association of COVID-AKI with kidney function remains unknown.

Objective: To assess long-term kidney outcomes of patients who had COVID-19-associated AKI.

Morphometric delineation of administrative boundaries and classification of threatened categories of small watersheds in transboundary rivers.

The ecological conservation of large rivers is impossible unless immediate attention is given to protecting their small tributaries at local levels. The natural boundaries of large river basins are shrinking because their tributaries and streams of different orders are disappearing at an unprecedented rate. Delineation of the fixed administrative boundaries (AB) to protect the natural boundary of small rivers and their classification into appropriate threatened categories, the present study was carried out on the 54.

Wearables in Cardiovascular Disease.

Wearable devices stand to revolutionize the way healthcare is delivered. From consumer devices that provide general health information and screen for medical conditions to medical-grade devices that allow collection of larger datasets that include multiple modalities, wearables have a myriad of potential uses, especially in cardiovascular disorders. In this review, we summarize the underlying technologies employed in these devices and discuss the regulatory and economic aspects of such devices as well as the future implications of their use.

Prevalence of Long COVID-19 and its Impact on Quality of Life Among Outpatients With Mild COVID-19 Disease at Tertiary Care Center in North India.

Literature is lacking on the spectrum of symptoms of long COVID-19 (defined as symptoms persisting beyond 28 days of diagnosis) and its impact on quality of life. This single-center, cross-sectional study included mild COVID-19 cases as determined by a positive real-time reverse transcription polymerase chain reaction test. Patients were contacted at least 28 days after diagnosis and were interviewed telephonically using semi-structured questionnaires for duration of symptoms, fatigue using Fatigue Severity Scale (FSS) and quality of life using the World Health Organization Quality of Life: Brief Version (WHOQOL-BREF).

Electronic structure calculations and quantum dynamics of rotational deexcitation of CNNC by He.

The quantum dynamics of rotational transitions of the diisocyanogen (CNNC) molecule undergoing collision with the helium (He) atom occurring in the interstellar medium (ISM) has been studied. The rotational deexcitation cross sections are extracted by first computing an potential energy surface of CNNC-He using the coupled-cluster with single and double and perturbative triple excitations with the F12a method (CCSD(T)-F12a) employing the aug-cc-pVTZ basis set. Utilizing the multipole expansions, collisional cross sections are determined for total energies of up to 1000 cm by the close coupling equations.
