Pollution control and biodiesel production with microalgae: new perspectives on the use of flat panel photobioreactors regarding variation in volume application rate.

In the present study, the microalga Arthrospira platensis DHR 20 was cultivated in vertical flat-plate photobioreactors (FPBRs) to bioremediate anaerobically digested cattle wastewater (ACWW) and used as a growth substrate. The final objective was to evaluate the properties of the oil extracted from this biomass to determine its potential for biodiesel production. The process was divided into five phases, varying the volume of the applied substrate: 1 L (Phase I), 5 L (Phase II), 10 L (Phase III), 15 L (Phase IV), and 20 L (Phase V).

Advancing Lifestyle Medicine in New York City's Public Health Care System.

Chronic diseases are the leading cause of death and disability in the United States, and much of this burden can be attributed to lifestyle and behavioral risk factors. Lifestyle medicine is an approach to preventing and treating lifestyle-related chronic disease using evidence-based lifestyle modification as a primary modality. NYC Health + Hospitals, the largest municipal public health care system in the United States, is a national pioneer in incorporating lifestyle medicine systemwide.

Patient-Reported Outcomes from a Pilot Plant-Based Lifestyle Medicine Program in a Safety-Net Setting.

Lifestyle medicine interventions that emphasize healthy behavior changes are growing in popularity in U.S. health systems.

Change in cardiometabolic risk factors in a pilot safety-net plant-based lifestyle medicine program.

Introduction: Interventions emphasizing healthful lifestyle behaviors are proliferating in traditional health care settings, yet there is a paucity of published clinical outcomes, outside of pay-out-of-pocket or employee health programs.

Methods: We assessed weight, hemoglobin A1c (HbA1c), blood pressure, and cholesterol for 173 patients of the Plant-Based Lifestyle Medicine Program piloted in a New York City safety-net hospital. We used Wilcoxon signed-rank tests to assess changes in means, from baseline to six-months, for the full sample and within baseline diagnoses (i.

Myocardial fibrosis and ventricular ectopy in patients with non-ischemic systolic heart failure: results from the DANISH trial.

Patients with non-ischemic systolic heart failure (HF) have increased risk of sudden cardiovascular death (SCD). The initiation and substrate for ventricular arrhythmias remains poorly understood. Our purpose was to describe the relationship between cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) and Holter recorded ventricular arrhythmic activity.

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) with postural orthostatic tachycardia syndrome after silicone breast implantation: Case report.

This study illustrates two patients who developed autoimmune/inflammatory syndrome induced by adjuvants (ASIA) with postural orthostatic tachycardia syndrome (POTS) after silicone breast implant (SBI) and improved after SBI extraction.

Addressing Psychosocial Stressors through a Community-Academic Partnership between a Museum and a Federally Qualified Health Center: A Qualitative Study.

Psychosocial stressors are prevalent and linked to worse health outcomes, but are less frequently addressed than physically apparent medical conditions at primary care visits. Through a community-academic partnership between an art museum and a federally qualified health center, we developed an innovative museum-based intervention and evaluated its feasibility and acceptability among diverse, underserved patients and its perceived effects on psychosocial stressors. Guided by experiential learning and constructivist approaches, the intervention consisted of a single, three-hour session that incorporated group discussions and interactive components, including art-viewing, sketching, and object-handling.

Genetic diversity and molecular survey of Trypanosoma (Megatrypanum ) theileri in cattle in Brazil's western Amazon region.

Trypanosoma (Megatrypanum) theileri is a flagellated protozoan that infects ruminants and it displays high genetic diversity. In this study, we investigated the prevalence rates of this protozoan based on hemoculture and molecular diagnosis. The isolates of T.

Inflammatory pseudotumor of the hip: a complication of arthroplasty to be recognized by the radiologist.

Soft tissue complications following hip arthroplasty may occur either in cases of total hip arthroplasty or in hip resurfacing, a technique that has become popular in cases involving young patients. Both orthopedic and radiological literatures are now calling attention to these symptomatic periprosthetic soft tissue masses called inflammatory pseudotumors or aseptic lymphocytic vasculites-associated lesions. Pseudotumors are associated with pain, instability, neuropathy, and premature loosening of prosthetic components, frequently requiring early and difficult reoperation.

Infection by Neospora caninum in dairy cattle belonging to family farmers in the northern region of Brazil.

Neosporosis is considered a major cause of abortion among cattle worldwide. The aim of this study was to investigate the prevalence of anti-Neospora caninum antibodies in dairy cattle and correlate them with possible risk factors on 63 small farms (family farms) in the municipality of Ji-Paraná, the main milk-producing region of the state of Rondônia, northern Brazil. For this purpose, 621 serum samples were collected from cows and were evaluated by means of the indirect fluorescence antibody test (IFAT).

The relationship of hospital charges and volume to surgical site infection after total hip replacement.

The purpose of this study was to analyze the effect of hospital volume and charges on the rate of surgical site infections for total hip replacements (THRs) in New York State (NYS). In NYS, higher volume hospitals have higher charges after THR. The study team analyzed 93,620 hip replacements performed in NYS between 2008 and 2011.

Effect of natural antioxidants on the lipase activity in the course of batch and continuous glycerolysis of babassu oil.

The effects of several natural antioxidants (copaiba oil, buriti oil, cocoa butter, tucuman butter, oregano and white thyme) were assessed in the enzymatic synthesis of monoglycerides (MAG) from the glycerolysis of babassu oil. The reactions were catalyzed by Burkholderia cepacia lipase immobilized on SiO2-PVA and the assays carried out in batch and continuous runs. Results were compared with those attained in the control reactions (without any strategy to avoid oxidation), and the best approach was tested in a continuous packed-bed reactor.

Complex Regional Pain Syndromes: guidelines for therapy.

This report aims to present an orderly approach to the treatment of Chronic Regional Pain Syndrome (CRPS) types I and II through an algorithm. The central theme is functional restoration: a coordinated but progressive approach that introduces each of the treatment modalities needed to achieve both remission and rehabilitation. Reaching objective and measurable rehabilitation goals is an essential element.

Sympathetic nerve blocks: in search of a role.

Objective: The role of sympathetic blocks in pain therapy is examined in the light of changing concepts of pain pathophysiology. A critical review of the literature also sought to develop an evidence-based analysis of outcome studies to provide recommendations for appropriate applications of sympathetic blocks, together with ideas for further clinically based research.

Methods: A focus on the pathophysiology of neuropathic and inflammatory pain disorders was used to help redefine what contribution, if any, was provided by the sympathetic system, to chronic pain states.

Epidural space as a Starling resistor and elevation of inflow resistance in a diseased epidural space.

Background And Objectives: The origin and the presence of negative pressure in the epidural space as well as the relationship of the extent of epidural anesthesia to epidural pressure has long been a subject of controversy. To further elucidate epidural pressure and its time course, the pressure at the needle tip was continuously measured as it traversed the interspinous ligament and the ligamentum flavum.

Methods: In a group of 22 patients, fluid was infused under gravity, and in a second group of 25 patients, boluses of fluid were administered at controlled infusion rates and under gravity.

Reflex sympathetic dystrophy: changing concepts and taxonomy.

We present a revised taxonomic system for disorders previously called reflex sympathetic dystrophy (RSD) and causalgia. The system resulted from a special consensus conference that was convened on this topic and is based upon the patient's history, presenting symptoms, and findings at the time of diagnosis. The disorders are grouped under the umbrella term CRPS: complex regional pain syndrome.

Perineal pain after rectal amputation: a 5-year follow-up.

A long-term study was undertaken on 286 patients who underwent perineal resection for rectal cancer to ascertain the incidence of chronic post-surgical pain in this group and to determine the likely cause for these pains. In 33 patients (11.5%) experiencing persistent perineal pain over the 5-year follow-up, most (70%) developed pain within weeks after surgery.

Nerve blocks in the diagnosis of low back pain.

The use of diagnostic injection techniques in the evaluation of low back pain disorders is a clinical judgment skill, based on applied anatomy, pharmacology of the agents employed, and the neurophysiology of pain. In earlier years, the focus was primarily on the anatomic basis of pain, with sometimes oversimplistic interpretations of the results obtained. Although an anatomic correlation of a subjective complaint remains the same diagnostic objective today, a clearer understanding of pain concepts has also given these injection techniques a greater sensitivity but narrower spectrum in their application.
