Pulmonary hamartoma is a common benign tumor that rarely degenerates into malignancy. We document a unique case of pulmonary hamartoma with malignant transformation into well differentiated liposarcoma, coexisting in proximity to pulmonary nodules representing benign metastasizing leiomyoma in a sixty-year-old lady.Management of recurrent symptomatic tracheobronchomalacia and tracheobronchial compression after prior aortopexy and tracheobronchopexy is a surgical challenge. In patients with right aortic arch, the course of the aortic arch over the right mainstem bronchus can result in superior and posterior compression of the airway. We present two cases of recurrent bronchomalacia and bronchial compression treated with descending aortic translocation. The addition of bronchial splinting to aortic translocation effectively relieved airway symptoms.

To characterize perceived proficiency in immediate postpartum long-acting reversible contraception (LARC) provision among resident physicians in obstetrics and gynecology and family medicine in Wisconsin.

We queried 254 Wisconsin obstetrics and gynecology or family medicine residents about competency and attitudes regarding family planning services via a confidential electronic survey. We used logistic regression to identify factors associated with the primary outcome of self-reported proficiency in immediate postpartum LARC.

We recruited participants from 3 of 3 (100%) obstetrics and gynecology and 9 of 15 (60%) family medicine residency programs, achieving a 74% response rate among trainees (187/254 individuals). Seven of 12 programs (58%) offered immediate postpartum LARC training [100% (3/3) obstetrics and gynecology; 44% (4/9) family medicine]. Forty-eight percent of residents [68% (27/40) obstetrics and gynecology and 60/141 (43%) family medicine, p < 0.01)] reported immediate postpartum LARC p should be supported to ensure that all trainees are proficient in placing subdermal implants and family physicians planning to provide obstetric care are trained in postpartum IUD placement.

  STATEMENT Family medicine physicians provide a significant portion of obstetric care, especially in rural areas. Family medicine residency programs should be supported to ensure that all trainees are proficient in placing subdermal implants and family physicians planning to provide obstetric care are trained in postpartum IUD placement.Organophosphorus insecticides (OPIs) have low persistence and are easily biodegradable in nature. The United States and India are the major countries producing OPIs of about 25% and 17% of the world, respectively. OPIs commonly used for agricultural practices occupy a major share in the global market, which leads to the increasing contamination of OPIs residues in various food chains. To overcome this issue, an enzymatic degradation method has been approved by several environmental toxic, and controlling agencies, including United States Environmental Protection Agency (USEPA). Different catalytic enzymes have been isolated and identified from various microbial sources to neutralize the toxic pesticides and/or insecticides. In this review, we have gathered information on OPIs biotransformation and their residual toxicity in the environment. Particularly, it focuses on OPIs degrading enzymes such as chlorpyrifos hydrolase, diisopropylfluorophosphatase, organophosphate acid anhydrolase, organophosphate hydrolases, and phosphotriesterases like lactonasesspecific activity either P-O link group type or P-S link group of pesticides. To summarize, the catalytic degradation of organophosphorus insecticides is not only profitable but also environmentally friendly. Hence, the enzymatic catalyst is an ultimate and super bio-weapon to mitigate or decontaminate various OPIs residues in both terrestrial and aqueous environments.Sodium percarbonate (SPC) is considered a potential alternative to liquid hydrogen peroxide (H2O2) in organic compounds contaminated water/soil remediation due to its regularly, transportable, economical, and eco-friendly features. The solid state of SPC makes it more suitable to remediate actual soil and water with a milder H2O2 release rate. Apart from its good oxidative capacity, alkaline SPC can simultaneously remediate acidized solution and soil to the neutral condition. Conventionally, percarbonate-based advanced oxidation process (P-AOPs) system proceed through the catalysis under ultraviolet ray, transition metal ions (i.e., Fe2+, Fe3+, and V4+), and nanoscale zero-valent metals (iron, zinc, copper, and nickel). 17-AAG concentration The hydroxyl radical (•OH), superoxide radical (•O2-), and carbonate radical anion (•CO3-) generated from sodium percarbonate could attack the organic pollutant structure. In this review, we present the advances of P-AOPs in heterogeneous and homogeneous catalytic processes through a wide range of activation methods. This review aims to give an overview of the catalysis and application of P-AOPs for emerging contaminants degradation and act as a guideline of the field advances. Various activation methods of percarbonate are summarized, and the influence factors in the solution matrix such as pH, anions, and cations are thoroughly discussed. Moreover, this review helps to clarify the advantages and shortcomings of P-AOPs in current scientific progress and guide the future practical direction of P-AOPs in sustainable carbon catalysis and green chemistry.The aim of the present study was development of activated carbon modified with iron (Fe@AC) and modified with iron and zirconium (Fe-Zr@AC) from the Tectona grandis sawdust (TGS) waste biomass and its potential applicability for the removal of As (III) from contaminated water by batch and column mode. The biomass waste was pre-treated with ferric chloride (FeCl3) and the mixture of FeCl3 and zirconium oxide (ZrO2) and then pyrolyzed at 500 °C for 2 h. The properties of both bioadsorbents were comprehensively characterized by using Scanning electron microscopy (SEM), Energy dispersive X-ray (EDX), Fourier transform infra-red spectroscopy (FTIR), X-ray diffraction (XRD), Particle Size analysis (PSA), point of zero charge (pHZPC), Brunauer-Emmett-Teller (BET) to prove successful impregnation of the Fe and Zr on the surface of AC of TGS. FTIR analysis clearly indicates the Fe and Fe-Zr complexation on biosorbents surface and biosorption of As (III). The results revealed that maximum As (III) removal was achieved 86.
