Comparative efficacy of carfilzomib, lenalidomide, and dexamethasone (KRd) versus bortezomib, lenalidomide, and dexamethasone (VRd) in newly-diagnosed multiple myeloma: A systematic review and meta-analysis.

In view of the increasing data evaluating carfilzomib-based induction for newly-diagnosed multiple myeloma (NDMM), we conducted a systematic review and meta-analysis comparing the efficacy of carfilzomib/lenalidomide/dexamethasone (KRd) versus bortezomib/lenalidomide/dexamethasone (VRd). Three studies totaling 1597 patients (50% KRd-treated, 50% VRd-treated) were included. Despite similar survival outcomes and overall response rate compared with the VRd arm, KRd-treated subjects showed higher odds of achieving complete responses and measurable residual disease negativity. Among patients with high-risk cytogenetics (n = 348), KRd was associated with significant improvement in progression-free survival (HR = 0.70; 95% CI = 0.50-0.97; p = .03; I2 = 0%), suggesting carfilzomib-based induction may be preferable in this NDMM subpopulation.

A Rare Complication of Leptospirosis: Weil's Disease Diagnosed in the United States.

Leptospirosis is mostly found in tropical regions such as Latin America and Southeast Asia. Here we present a case of leptospirosis in the United States in a 43-year-old African American male who had complications such as sepsis, acute renal failure, hyperbilirubinemia, and transaminitis. Through this case report, we want to highlight the rare occurrence of this infection in the United States. It should be considered high in the list of differential diagnoses for patients traveling to underdeveloped countries and participating in adventure sports. Early recognition and treatment of leptospirosis are essential in decreasing life-threatening complications.

Pharmacist telehealth in an underserved urban population with type 2 diabetes mellitus.

BACKGROUND: During the pre-vaccine months of the COVID-19 pandemic, pharmacists providing comprehensive medication management to underserved patients with type 2 diabetes mellitus at an urban Federally Qualified Healthcare Center shifted to telephone-based telehealth. OBJECTIVES: This retrospective, observational cohort study evaluated the effectiveness of clinical pharmacist telehealth while identifying associations between patient characteristics and efficacy measures. METHODS: Patients with uncontrolled type 2 diabetes (hemoglobin A1c (HbA1c) ≥ 8%) with a clinical pharmacist visit between April 1 and August 31, 2020, were included. Telehealth effectiveness was measured by the proportions of: 1) patients reached, 2) appointments completed, and 3) the median change in HbA1c from baseline. Interventions by the clinical pharmacist were analyzed as a secondary outcome. RESULTS: There were 181 patients scheduled and 172 (95%) of those patients kept at least one appointment. Of the 667 appointments scheduled, 73% were kept. Median HbA1c was reduced from 10.2% to 9.2% over 5 months of follow-up, and 24.6% of patients achieved a HbA1c < 8% (n = 138, p < 0.0001 for each). Greater HbA1c changes were associated with higher baseline blood glucose (p = 0.01), higher baseline HbA1c (p < 0.0001), non-insulin medications at baseline (p = 0.007) and among those with more kept visits (p = 0.03). The healthcare quality impact of interventions during each appointment was favorable; 83.3% brought care to a higher standard, 1.9% averted major organ dysfunction and 0.4% prevented death. CONCLUSIONS: Clinical pharmacist telehealth was effective for providing patient-centered diabetes care when in-person office visits were not an option.

Rapid decomposition of rice straw by application of a novel microbial consortium and study its microbial community dynamics.

Rice straw decomposition is an attractive solution to open-field burning but the traditional method has slow kinetics and takes 60-90 days to obtain mature compost. In this study, we propose to boost up the decomposition process by addition of a novel microbial consortium rich in lignocellulolytic microbes. C: N ratio of the compost reached 11.69% and degradation efficiency of cellulose and hemicellulose was found to be 64 and 87% respectively within 25 days. Lignocellulolytic activity of the microbial consortium was confirmed by plate and activity assay. These parameters clearly indicated that a mature compost was obtained in 25 days. The 16S rRNA gene amplicon sequencing and functional analysis of predicted genes indicated amino acid and carbohydrate metabolism as the major metabolic pathway during composting. The tertiary level of functional analysis revealed the major metabolic pathways in the bacterial communities as pentose phosphate pathway, glycolysis and tricarboxylic acid cycle.

Valorization of microalgae biomass into bioproducts promoting circular bioeconomy: a holistic approach of bioremediation and biorefinery.

The need for alternative source of fuel has demanded the cultivation of 3rd generation feedstock which includes microalgae, seaweed and cyanobacteria. These phototrophic organisms are unique in a sense that they utilise natural sources like sunlight, water and CO2 for their growth and metabolism thereby producing diverse products that can be processed to produce biofuel, biochemical, nutraceuticals, feed, biofertilizer and other value added products. But due to low biomass productivity and high harvesting cost, microalgae-based production have not received much attention. Therefore, this review provides the state of the art of the microalgae based biorefinery approach to define an economical and sustainable process. The three major segments that need to be considered for economic microalgae biorefinery is low cost nutrient source, efficient harvesting methods and production of by-products with high market value. This review has outlined the use of various wastewater as nutrient source for simultaneous biomass production and bioremediation. Further, it has highlighted the common harvesting methods used for microalgae and also described various products from both raw biomass and delipidified microalgae residues in order to establish a sustainable, economical microalgae biorefinery with a touch of circular bioeconomy. This review has also discussed various challenges to be considered followed by a techno-economic analysis of the microalgae based biorefinery model.

Felty syndrome: a case report.

BACKGROUND: Felty syndrome is a rare manifestation of chronic rheumatoid arthritis in which patients develop extraarticular features of hepatosplenomegaly and neutropenia. The typical presentation of Felty syndrome is in Caucasians, females, and patients with long-standing rheumatoid arthritis of 10 or more years. This case report presents a patient with an early-onset and atypical demographic for Felty syndrome. CASE PRESENTATION: Our patient is a 28-year-old African American woman with past medical history of rheumatoid arthritis diagnosed in 2017, asthma, pneumonia, anemia, and mild intellectual disability who was admitted to inpatient care with fever, chills, and right ear pain for 7 days. The patient's mother, also her caregiver, brought the patient to the hospital after symptoms of fever and ear pain failed to improve. Our patient was diagnosed with sepsis secondary to pneumonia and urinary tract infection. She had been admitted twice in the past year, both times with a diagnosis of pneumonia. During this visit in September 2019, it was discovered that the patient had leukopenia and neutropenia. Bone marrow biopsy revealed increased immature mononuclear cells with left shift and rare mature neutrophils. During the hospital course, the patient was provisionally diagnosed with Felty syndrome and treated with adalimumab and hydroxychloroquine for her rheumatoid arthritis. Her sepsis secondary to pneumonia and urinary tract infection was treated with ceftriaxone and doxycycline, which was later switched to cefepime because of positive blood and urine cultures for Pseudomonas aeruginosa. She was discharged with stable vital signs and is continuing to control her rheumatoid arthritis with adalimumab. CONCLUSION: This case report details the clinical course of sepsis secondary to pneumonia and urinary tract infection in the setting of Felty syndrome. Our patient does not fit the conventional profile for presentation given her race, age, and the length of time following diagnosis of rheumatoid arthritis.

Clinical Case Report: Dissociation of Clinical Course of Coexisting Autoimmune Hepatitis and Graves Disease.

OBJECTIVE: Concurrent autoimmune disorders, including autoimmune hepatitis (AIH), with Graves disease have been reported. Glucocorticoids can simultaneously lower thyroid hormone levels and treat AIH. Recurrence of hyperthyroidism is associated with recurrence of hepatitis. We present a case of coexisting AIH and Graves thyrotoxicosis, which improved with prednisone, but the thyrotoxicosis recurred during a prednisone taper while the hepatitis stayed in remission. METHODS: Evaluation included measurements of liver enzyme levels, thyroid function tests, and thyroid-stimulating antibodies as well as abdominal ultrasound, magnetic resonance imaging, and liver biopsy. RESULTS: A 47-year-old woman presented with nausea and jaundice. Workup showed an aspartate aminotransferase level of 1956 (reference, 10-42) U/L and alanine aminotransferase level of 1634 (reference, 14-54) IU/L. The liver biopsy was consistent with AIH. Nine months later, she reported palpitations, heat intolerance, and weight loss and was diagnosed with Graves disease. The patient received prednisone at 60 mg daily, and the liver and thyroid functions normalized after 1 month. Prednisone was tapered to 5 mg daily. Seven months later, she presented with a thyroid-stimulating hormone level of 0.049 (reference, 0.340-5.6) µIU/mL) and free thyroxine level of 3.96 (reference, 0.58-1.64) ng/dL. Liver enzymes remained at normal levels. Prednisone was increased from 5 to 20 mg to treat hyperthyroidism. The patient was referred for thyroidectomy for a diagnosis of Graves disease with thyrotoxicosis. CONCLUSION: This case is an example of coexisting autoimmune diseases, Graves disease and AIH, with different clinical courses. Despite initial resolution with glucocorticoid therapy, Graves disease recurred, while AIH stayed in remission.

Community Violence, PTSD, Hopelessness, Substance Use, and Perpetuation of Violence in an Urban Environment.

We investigated the relationships among chronic violence exposure, post-traumatic stress disorder (PTSD) symptom severity, hopelessness, substance use, and perpetuation of violence to facilitate the development of trauma-related interventions for residents of Newark, NJ. A convenience sample of Newark residents (N = 153) was recruited from community centers during various events in 2016-2017. Anonymous, self-report survey measures included a PTSD screen (PCL-C), Beck's Hopelessness Scale, the CAGE questionnaire, and a CDC Health Behavior Scale. Descriptive statistics, Pearson's correlations, Chi square analyses, logistic, and linear regressions were used for analysis. Thirty percent (95% CI [22.7, 37.4]) of our sample screened positive for PTSD. Drug and alcohol use, fighting, and hopelessness were related to severity of PTSD symptoms (p < 0.05). Female gender, CAGE scores, and hopelessness predicted the severity of PTSD symptoms (R2 = 0.354, p < 0.05). Our data has informed the development of a resilience support group currently in the pilot stage for community members.

Safety and Feasibility of Transradial Access in Patients Presenting With Traumatic Injuries: A Single Urban Center Experience.

PURPOSE: To evaluate the efficacy, safety, and feasibility of transradial approach (TRA) for endovascular management of traumatic bleeding. MATERIALS AND METHODS: A retrospective review was performed at a single level 1 trauma institution from August 2018 to July 2019. Patients presented to the interventional radiology department who were intended to be treating using TRA for the management of trauma-induced bleeding were selected. Demographics, indication for embolization, embolization site, preprocedural labs, hemodynamic stability, technical success, and complications were recorded. RESULTS: Transradial approach was attempted in 29 (74.4%) of the 39 patients identified by operators who prefer TRA. Four patients received treatment using TRA on 2 separate occasions, for a total of 33 procedures completed with a technical success of 97% (32/33). Transradial approach was safely completed in 9 patients (27.3%) with preprocedural hemodynamically unstable status. For the 10 patients who received treatment via a transfemoral approach (TFA), traumatic disfiguration of the left upper extremity, preexisting arterial lines placed by the trauma team, and external iliac artery injuries requiring covered stent placement were the most common indications for TFA over TRA. There were no procedural or access site-related complications. CONCLUSION: Transradial approach for the endovascular management of bleeding in a trauma setting is safe and effective with a high technical success rate and no complications.

Trauma CT evaluation prior to selective angiography in patients with traumatic injuries: negative predictive power and factors affecting its utility.

PURPOSE: To evaluate the predictive power of arterial injury detected on contrast-enhanced CT (trauma CT (tCT)) imaging obtained prior to selective angiography for treatment of patients with traumatic abdominal and pelvic injuries. MATERIALS AND METHODS: A retrospective chart review was performed of all patients who underwent angiography after undergoing contrast-enhanced CT imaging for the evaluation/treatment of traumatic injuries to the abdomen and pelvis between March 2014 and September 2018. Data collection included demographics, pertinent history and physical findings, CT and angiography findings, treatment information, and outcomes. RESULTS: Eighty-nine (63 males, mean age = 45.8 ± 20.5 years) patients that were found to have 102 traumatic injuries on tCT and subsequently underwent angiography met inclusion criteria for this study. Sixty-four injuries demonstrated evidence of traumatic vascular injury on initial tCT. A negative tCT was able to predict subsequent negative angiography in 83% of cases (negative predictive power = 83%). The ability of tCT to rule out a positive finding on subsequent angiography was also 83% (sensitivity = 83%). The average systolic blood pressure and hemoglobin concentration at the time of tCT were higher in patients who had positive tCT than in patients with negative tCT (p < 0.05 and p < 0.01, respectively). The average time to angiography was greater in patients whom had subsequent negative angiography than the patients who had subsequent positive angiography (p < 0.05). CONCLUSION: Contrast-enhanced CT imaging may be able to help stratify patients who may have subsequent negative angiograms. Hemodynamic factors may affect sensitivity of tCT. Shorter time to angiography may increase the chance of identifying the injury on subsequent angiography.

Readability Assessment of Internet-based Patient Education Materials Related to Treatment Options for Benign Prostatic Hyperplasia.

RATIONALE AND OBJECTIVES: To assess the current readability levels for online Internet-Based Patient Education Materials (IPEMs) related to treatment options for benign prostatic hyperplasia, including transurethral resection of prostate (TURP) and prostate artery embolization (PAE). MATERIALS AND METHODS: Using the Google search engine we identified 40 IPEMs pertaining to TURP and PAE. Readability analysis was performed using the following algorithms: Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Formula (FKGL), Simple Measure of Gobbledygook (SMOG), and the Gunning Frequency of Gobbledygook (GFOG). Scores are categorized by difficulty (FRES) and grade level (FKGL, SMOG, GFOG). RESULTS: Only 7.5% (3/40) websites met the United States Department of Health and Human Services recommendation of a sixth grade or lower comprehension levels, with FRES scores in the "fairly easy" category. Comparison of TURP to PAE groups showed that TURP readability scores with respect FRES and FKGL were significantly easier to read. According to SMOG and GFOG analysis there was no difference between the two groups by grade level, which demonstrated an average at the 12th grade reading level. Subgroup analysis of IPEM type, categorized as Health Networks (12), University Hospitals (14), Clinical Practices (6), and Miscellaneous (8), found no difference in reading level across all scoring systems. CONCLUSION: Currently available IPEMs pertaining to benign prostatic hyperplasia treatment options are written at a level that is too difficult for the average American to understand. Physicians and health networks should take United States Department of Health and Human Services recommendations into consideration when designing IPEMs to optimize accessibility of health information to improve patient compliance and outcomes.

The role of socioeconomic disparity in colorectal cancer stage at presentation.

Colorectal cancer, despite multiple screening measures being available, is the second leading cause of death due to cancer. Cancer stage at diagnosis is an important determinant of survival, where earlier stages have significantly increased rates of survival. By looking at various social health disparities (at a patient and geographic level) and their effect on stage at presentation, we will gain a better understanding of the effect they have on cancer outcomes. Data were collected from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) database for the years 2007-2014. Covariates extracted were patient-level variables such as age, race, primary site, state/county, insurance status as well as county-level data which included percent urban population, median family income, rural-urban continuum code classification, percent of population that has not completed high school, percent of population below the poverty line, percent of population foreign-born, percent of language-isolated persons, and unemployment rate. The primary outcome analyzed was cancer staging at diagnosis. A χ2 analysis and multivariate binary logistic regression was modeled to elucidate the associations between study covariates and late stage of cancer presentation. Chi-squared analysis demonstrated significant associations (at p < 0.05) between stage of diagnosis with race, age, insurance status, location of primary site, percent of population below poverty line, percent of language-isolated persons, and percent of unemployed. To help reduce these disparities, community resources and increased screening and prevention techniques must be implemented to target the unique populations at greatest risk for developing the disease.

Comprehensive evaluation of microalgal based dairy effluent treatment process for clean water generation and other value added products.

The current study demonstrates a comprehensive investigation on clean water generation from raw dairy wastewater (RDW) using a robust microalgal strain, Ascochloris sp. ADW007 and its growth, biomass, and lipid productivities in outdoor conditions. Microalgal treatment studies were conducted in column photobioreactor (CPB) and flat-pate photobioreactor (FPB), where the volumetric algal biomass productivity in RDW was significantly increased in both CPB (0.284 ± 0.0017 g/L/d) and FPB (0.292 ± 0.0121 g/L/d) as compared to synthetic mediums viz., BG11 and TAP, respectively, with enhanced lipid content. Maximum lipid accumulation of 33.40% was obtained within 7 d growth. The volumetric and areal lipid productivities in CPB and FPB were 94 mg/L/d and 5.597 g/m2/d, and 98 mg/L/d and 9.754 g/m2/d, respectively. Chemiflocculation, filtration, and centrifugation techniques were employed for harvesting microalgal biomass. Among the flocculants, 0.08% (w/v) FeCl3 harvested >99% of algal cells within 5 min, while 0.03% (w/v) cetyl trimethyl ammonium bromide and 0.125% (w/v) sodium hydroxide harvested >96% of the cells in 30 and 60 min. After microalgal treatment, >80% of clean and odorless water was obtained with reduction in 94-96% of COD, 72-80% of nitrate and 80-97% of total phosphate, respectively. Highlights Utilization of 100% raw dairy wastewater without any treatment. Production of clean and odorless water for recycle and reuse. COD, nitrate and total phosphate reduction by 94-96%, 72-80%, and 80-97% after treatment. Microalgal treatment studies in simple column and flat-plate photobioreactors. Biomass and lipid production as other value added by-products.

Fever and Reversible Laboratory Abnormalities Associated with Prolonged Use of Piperacillin-Tazobactam in Children.

Piperacillin-tazobactam is used frequently in pediatric patients with complicated appendicitis and other intra-abdominal infections. We report 10 pediatric patients who developed a piperacillin-tazobactam-associated adverse reaction characterized by fever, rash, hematologic abnormalities and transaminitis. Physicians should be aware of this entity in patients treated with a prolonged course of piperacillin-tazobactam. Prompt identification can obviate unnecessary diagnostic testing and treatment.

Improved detection of drugs of abuse using high-performance ion mobility spectrometry with electrospray ionization (ESI-HPIMS) for urine matrices.

High-performance ion mobility spectrometry (HPIMS) with electrospray ionization (ESI) has been used to separate drugs of abuse compounds as a function of drift time (ion mobility), which is based on their size, structural shape, and mass-to-charge. HPIMS has also been used to directly detect and identify a variety of the most commonly encountered illegal drugs, as well as a mixture of opiates in a urine matrix without extra sample pretreatment. HPIMS has shown resolving power greater than 65 comparable to that of high-performance liquid chromatography (HPLC) with only 1 mL of solvent and sample required using air as the IMS separation medium. The HPIMS method can achieve two-order of magnitude linear response, precise drift times, and high peak area precision with percent relative standard deviations (%RSD) less than 3% for sample quantitation. The reduced mobilities measured agree very well with other IMS measurements, allowing a simple "dilute-and-shoot" method to be used to detect a mixture of codeine and morphine in urine matrix.
