Trends in Industry Payments to Dermatologists: A 5-Year Analysis of Open Payments Data (2017-2021).

Financial relationships between dermatologists and industry are prevalent and may have implications for patient care. To analyze reported industry payments made to dermatologists, we performed a retrospective analysis of the Centers for Medicare and Medicaid Services Open Payments database (OPD) from January 1, 2017, to December 31, 2021. During this 5-year period, a total of $278 million in industry payments were made to dermatologists.

Efficient oil spill cleanup from water: Investigating the effectiveness of a sustainable anti-swelling hydrogel for rapid water repellency and oil absorption.

Considering the significant harm caused to aquatic ecosystems and marine life by oil spills and the discharge of oily wastewater, there is a pressing need to address this issue to protect our environment and prevent the wastage of valuable resources. We introduced a two-step approach to create an anti-swelling, water-repellent sorbent using a green polysaccharide called gum gellan, functionalized with Octadecyl trichlorosilane (OTS) through dip coating method. Natural gums like gellan have high absorption capability due to their large surface area.

CD5+ Primary Cutaneous Diffuse Large B-Cell Lymphoma, Leg Type, Presenting as an Asymptomatic Nodule.

Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT), is a rare and aggressive variant of primary cutaneous lymphoma that typically expresses B cells as well as MUM1/IRF4, BCL2, and FOXP1, whereas BCL6 may be present or undetectable. We present a case of CD5+ PCDLBCL-LT presenting as a 6 mm pink-bluish nodule on the mid-left thigh, which was concerning for basal cell carcinoma. The histological examination reveals the presence of an intradermal proliferation of large, atypical CD5+, CD20+ BCL2+, BCL6+, MUM-1+, and Cyclin-D1+ lymphocytes in a nodular, diffuse interstitial and perivascular distribution.

A multimodal sensing ring for quantification of scratch intensity.

Background: An objective measurement of chronic itch is necessary for improvements in patient care for numerous medical conditions. While wearables have shown promise for scratch detection, they are currently unable to estimate scratch intensity, preventing a comprehensive understanding of the effect of itch on an individual.

Methods: In this work, we present a framework for the estimation of scratch intensity in addition to the detection of scratch.

Performance Evaluation of Gum Gellan-Based Hydrogel as a Novel Adsorbent for the Removal of Cationic Dyes: Linear Regression Models.

In this work, the suitability and efficacy of the previously reported biodegradable gellan gum (GG)-based hydrogel have been thoroughly investigated with respect to the adsorption mechanisms of malachite green (MG) and methylene blue (MB) dyes. The dyes' removal from aqueous solutions using GG-cl-poly(AA) as an adsorbent material has been studied in a discontinuous system with respect to contact time, dose, pH, and temperature. The synthesized hydrogel was characterized by FT-IR, TGA, XRD, H NMR, and FE-SEM.

DOE-based synthesis of gellan gum-acrylic acid-based biodegradable hydrogels: screening of significant process variables and field studies.

The current study uses the free radical graft copolymerization of acrylic acid as a monomer, ,-methylene-bis-(acrylamide) as a crosslinker and ammonium persulfate as an initiator to synthesise GG-cl-poly(AA) hydrogels based on gellan gum utilising response surface methodology (RSM). A full factorial design was used to obtain the greatest percent swelling ( ), and key process variables were determined using the Pareto chart. To make the procedure cost-effective, a multiple regression model employing ANOVA projected a linear model with a maximum percentage swelling of 556 at the lowest concentration of all three studied factors.

A Review of Adsorbents for Heavy Metal Decontamination: Growing Approach to Wastewater Treatment.

Heavy metal is released from many industries into water. Before the industrial wastewater is discharged, the contamination level should be reduced to meet the recommended level as prescribed by the local laws of a country. They may be poisonous or cancerous in origin.

Fatal Disseminated Mucormycosis in a Hematological Immunocompromised Patient with Extensive Voriconazole Exposure: A Case Report and Review of the Literature.

Disseminated mucormycosis is a rare, opportunistic, and aggressive infection typically presenting in immunocompromised patients. Herein, we report a 55-year-old male with a past medical history of Philadelphia-negative B-cell acute lymphoblastic leukemia who presented with a 2-month history of non-painful necrotic ulcers on the nose, knuckles, elbow, foot, and scrotum following 3 months of voriconazole (VRC) exposure in the setting of an unrelated fungal pneumonia. Our case reinforces the virulent and often fatal nature of the disease amongst immunocompromised patients, along with extensive VRC exposure as a possible supplementary risk factor.

Shifting from volume to economic value in virtual water allocation problems: A proposed new framework and methodology.

Purpose: The water footprint provided a full methodology to operationalise the virtual water concept (the volume of water used along a supply chain to produce products and services). A key theme in the water footprint literature is the efficient allocation of water resources at the global scale given the feasibility of trading water intensive commodities from water rich to water poor areas: this is an economic problem of resource allocation between alternative and competing demands, albeit with a novel international component. Moreover, given that price signals indicating relative scarcity are usually either absent or distorted for water, it is also a problem that can be seen through the lens of environmental (or non-market) valuation.

Dataset on the in-stream and off-stream economic value of water.

This dataset contains 706 estimates of the economic value of water; it has been compiled from published sources. Economic values are provided for three off-stream uses (agriculture/irrigation, industry, and municipal) and three in-stream ecosystem services (recreation, waste assimilation, and wildlife habitat). The dataset covers per period and capitalised asset values.

Neem gum based pH responsive hydrogel matrix: A new pharmaceutical excipient for the sustained release of anticancer drug.

The present research work was aimed to synthesize neem gum-based site-specific drug delivery device for anticancer drug methotrexate at different pH condition. The hydrogel-based drug delivery device was synthesized by optimizing reaction parameters using a factorial design approach response surface method. This model comprised of various sets of reactions with varying concentrations of solvent, crosslinker, initiator and monomer under microwave radiation.

Connective Tissue Nevi: A Review of the Literature.

Connective tissue nevi (CTN) are hamartomas of the dermis, with the 3 main components being collagen, elastin, and proteoglycans. Each subtype can present as a solitary lesion or multiple lesions. They could present as part of systemic diseases or inherited disorders.

Nitrogen accumulation and partitioning in a High Arctic tundra ecosystem from extreme atmospheric N deposition events.

Arctic ecosystems are threatened by pollution from recently detected extreme atmospheric nitrogen (N) deposition events in which up to 90% of the annual N deposition can occur in just a few days. We undertook the first assessment of the fate of N from extreme deposition in High Arctic tundra and are presenting the results from the whole ecosystem (15)N labelling experiment. In 2010, we simulated N depositions at rates of 0, 0.

Acral melanocytic lesions in the United States: Prevalence, awareness, and dermoscopic patterns in skin-of-color and non-Hispanic white patients.

Background: Acral lentiginous melanoma has increased mortality compared with other melanoma subtypes and disproportionately affects ethnic minorities. Acral melanocytic lesions have not been well studied in diverse populations of the United States.

Objective: We sought to assess the prevalence, awareness, and dermoscopic patterns of acral melanocytic lesions in skin-of-color and non-Hispanic white patients.
