A Critical Analysis of the Research Concerning the Effects of Competitive Athletics for Women and Girls
It is the opinion of a number of authorities - medical, educational, physical education and the like that participation in competitive sports programs of any sort by women has an injurious or adverse effect on their physiological functional.
Some students take the position, based upon research findings that participation in competitive sports by women is injurious to them physiological. Others are equally insistant that participation in competitive sports has no adverse physiological effects on women.
It appears that the argument against the participation in competitive sports by women to participate in sports have been severly limited. The arguments run (a) that the participation of women in competitive sports is socially undesirable, (b) that women are not emotionally fitted to withstand the tensions incurred in competitive sports, (c) the effects of competitive sports, particularly during the menstrual period, not only effect the woman adverse physiologically possibly for life, but also may danger the natural reason for women\u27s existence - childbirth. Whether or not these claims are true require critical examination of the research presently available.
Since there have been many divergent ideas expressed as to women and girls participation in competitive sports, the purpose of this treatise is to analyze philosophically the data concerning competitive athletics for women and girls. The data used for this investigation was confined to the writings of authorities in the field of Physical Education and those related anatomical, physiological, sociological writings that have bearing on the topic
Quantitative Analysis of Heavy Metals in Children’s Toys and Jewelry: A Multi-Instrument, Multi-Technique Exercise in Analytical Chemistry and Public Health
For most chemistry curricula, laboratory-based activities in quantitative and instrumental analysis continue to be an important aspect of student development/training, one that can be more effective if conceptual understanding is delivered through an inquiry-based process relating the material to relevant issues of public interest and student career trajectories. Laboratory experiences that actively engage students in this manner can be difficult to identify and execute. A special topics, project-based laboratory module is presented here that utilizes multiple techniques and instruments to investigate toxic metal content (lead, cadmium, and arsenic) in children’s toys and toy jewelry. The module effectively illustrates a considerable number of fundamental and advanced quantitative analysis principles including sample digestion, Beer–Lambert law, calibration curve, and standard addition analyses, as well as instrumental analysis considerations of atomic absorption spectroscopy including atomization efficiency (e.g., flames vs furnaces), matrix modifiers, and nondestructive spectroscopy. Module effectiveness stems from the illustration of critical chemical analysis principles in the context of projects with student-directed hypotheses and experimental results that are clearly relevant to the interface of basic science, medicine, and public health: primary career interests for a significant number of undergraduates in the physical and life sciences
Constitutive, but Not Challenge-Induced, Interleukin-10 Production Is Robust in Acute Pre-Pubescent Protein and Energy Deficits: New Support for the Tolerance Hypothesis of Malnutrition-Associated Immune Depression Based on Cytokine Production in vivo
The tolerance model of acute (i.e., wasting) pre-pubescent protein and energy deficits proposes that the immune depression characteristic of these pathologies reflects an intact anti-inflammatory form of immune competence that reduces the risk of autoimmune reactions to catabolically released self antigens. A cornerstone of this proposition is the finding that constitutive (first-tier) interleukin(IL)-10 production is sustained even into the advanced stages of acute malnutrition. The IL-10 response to inflammatory challenge constitutes a second tier of anti-inflammatory regulation and was the focus of this investigation. Weanling mice consumed a complete diet ad libitum, a low-protein diet ad libitum (mimicking incipient kwashiorkor), or the complete diet in restricted daily quantities (mimicking marasmus), and their second-tier IL-10 production was determined both in vitro and in vivo using lipopolysaccharide (LPS) and anti-CD3 as stimulants of innate and adaptive defences, respectively. Both early (3 days) and advanced (14 days) stages of wasting pathology were examined and three main outcomes emerged. First, classic in vitro systems are unreliable for discerning cytokine production in vivo. Secondly, in diverse forms of acute malnutrition declining challenge-induced IL-10 production may provide an early sign that anti-inflammatory control over immune competence is failing. Thirdly, and most fundamentally, the investigation provides new support for the tolerance model of malnutrition-associated inflammatory immune depression

Feasibility and efficacy of pairing fecal immunochemical testing with mammography for increasing colorectal cancer screening among uninsured Latinas in northern Manhattan
Objectives: We evaluated the feasibility and efficacy of a program to promote colorectal cancer screening (CRC) among uninsured Latinas receiving mammography through a cancer screening clinic in northern Manhattan.
Methods: Between August 2009 and March 2010, unscreened, average CRC risk, uninsured Latinas, aged 50–64 years, undergoing mammography received a screening recommendation, education, and fecal immunochemical test (FIT). Socio-demographic information and level of acculturation was collected. Screening compliance was assessed.
Results: Of 651 Latinas evaluated, 210 were eligible and, of these, 94% (n = 197) consented to participate; 441 were excluded because they were up-to-date with CRC screening (n = 130), less than 50 (n = 285) or greater than 64 (n = 26) years of age. After intervention, 177 (90%) completed FIT. Within 2 weeks, 87% completed the FIT, and 69% did so with no reminder calls. Acculturation was significantly lower among screeners (p = 0.014). Compared with non-screeners, screeners were more likely to be foreign-born (p = 0.009), to speak only Spanish (p = 0.043), and to prefer to read (p = 0.037), and think (p = 0.015) in Spanish.
Conclusion: This study suggests that pairing CRC education and screening with mammography is both feasible and efficacious
Multi-technique Quantitative Analysis and Socioeconomic Considerations of Lead, Cadmium, and Arsenic in Children\u27s Toys and Toy Jewelry
A wide spectrum and large number of children’s toys and toy jewelry items were purchased from both bargain and retail vendors and analyzed for arsenic, cadmium, and lead metal content using multiple analytical techniques, including flame and furnace atomic absorption spectroscopy as well as X-ray fluorescence spectroscopy. Particularly dangerous for young children, metal concentrations in toys/toy jewelry were assessed for compliance with current Consumer Safety Product Commission (CPSC) regulations (F963-11). A conservative metric involving multiple analytical techniques was used to categorize compliance: one technique confirmation of metal in excess of CPSC limits indicated a “suspect” item while confirmation on two different techniques warranted a non-compliant designation. Sample matrix-based standard addition provided additional confirmation of non-compliant and suspect products. Results suggest that origin of purchase, rather than cost, is a significant factor in the risk assessment of these materials with 57% of toys/toy jewelry items from bargain stores non-compliant or suspect compared to only 15% from retail outlets and 13% if only low cost items from the retail stores are compared. While jewelry was found to be the most problematic product (73% of non-compliant/suspect samples), lead (45%) and arsenic (76%) were the most dominant toxins found in non-compliant/suspect samples. Using the greater Richmond area as a model, the discrepancy between bargain and retail children’s products, along with growing numbers of bargain stores in low-income and urban areas, exemplifies an emerging socioeconomic public health issue

Fecal-Based Colorectal Cancer Screening Among the Uninsured in Northern Manhattan
Background
Colorectal cancer (CRC) screening reduces CRC mortality; however, for many reasons, uninsured individuals are less likely to utilize CRC screening tests.
Purpose
To compare CRC screening behaviors and outcomes with guaiac fecal occult blood testing (gFOBT) from 1998 to 2006 and fecal immunochemical testing (FIT) from 2006 to 2010 in a community-based program serving uninsured patients in northern Manhattan.
Methods
In 2013, we conducted a retrospective record review of individuals aged ≥50 years who received fecal-based CRC screening at the Northern Manhattan Cancer Screening Partnership between 1998 and 2010. Included were those with household income ≤250% of the federal poverty level, no medical insurance coverage, and who were not up to date with CRC screening. We assessed screening positivity rate, positive predictive value, differences in the use of diagnostic colonoscopy, colonoscopic findings, and adenoma detection rates for gFOBT versus FIT.
Results
In total, 7,710 patients completed CRC screenings (4,951 gFOBT and 2,759 FIT). The majority were female, Hispanic, foreign born, and young at age of first screening. Compared to gFOBT, FIT detected twice as many positive tests (3.2% vs 1.5%, p≤0.001) and had a higher adenoma detection rate (18.2 vs 11.8, p=0.002).
Conclusions
The improved positivity and adenoma detection rates with greater number of screening tests over time favor the use of FIT over gFOBT for colorectal screening among uninsured populations in northern Manhattan
Sprinkler irrigation system field checklist
This recommendation came out of a noted need by the ASABE NRES-241 sprinkler irrigation committee in 2019 committee meeting for a simple checklist to quickly educate new center pivot operators on what to look for to determine if a center pivot is operating at designed performance. This checklist is meant to be simple and user friendly. Simple and clear language was incorporated purposefully. It is intended as a quick guide to new irrigators, or as a reminder to more experienced irrigators as to what to check to ensure efficient and effective center pivot and linear move irrigation system operation for optimal performance. Different checklists were developed for various frequencies of system evaluation. This was done as a cooperative project of the sprinkler irrigation committee members as an outcome of this stated need. It is hoped that this checklist can be adapted and used by growers, consultants, and other irrigators
Patient outcomes and characteristics in a contemporary quaternary Canadian cardiac intensive care unit
BACKGROUND: The modern-day cardiac intensive care unit (CICU) has evolved to care for patients with acute critical cardiac illness. We describe the current population of cardiac patients in a quaternary CICU. METHODS: Consecutive CICU patients admitted to the CICU at the Toronto General Hospital from 2014 to 2020 were studied. Patient demographics, admission diagnosis, critical care resources, complications, in-hospital mortality, and CICU and hospital length of stay were recorded. RESULTS: A total of 8865 consecutive admissions occurred, with a median age of 64.9 years. The most common primary cardiac diagnoses were acute decompensated heart failure (17.8%), non ST-elevation myocardial infarction (16.8%), ST-elevation myocardial infarction (15.5%), and arrhythmias (14.7%). Cardiogenic shock was seen in 13.2%, and out-of-hospital cardiac arrest in 4.1%. A noncardiovascular admission diagnosis accounted for 13.9% of the cases. Over the period studied, rates of admission were higher for cardiogenic shock (P < 0.001 for trend), with a higher use of critical care resources. Additionally, rates of admission were higher in female patients and those who had chronic kidney disease and diabetes. The in-hospital mortality rate of all CICU admissions was 13.2%, and it was highest in those with noncardiac conditions, compared to the rate in those with cardiac diagnoses (29.4% vs 10.6%, P < 0.001). CONCLUSIONS: Given the trends of higher acuity of patients with cardiac critical illness, with higher use of critical care resources, education streams for critical care within cardiology, and alternative pathways of care for patients who have lower-acuity cardiac disease remain imperative to manage this evolving population
