The effect of organic versus chemical fertilizers on insect pathogens
Insects such as the black cutworm are a major pest of seedling corn in Corn Belt states. Both the nematode Steinernema carpocapsae and the fungus Beauveria bassiana are potential biological control agents of this pest Because their survivability depends on moisture and they are affected adversely by nitrogen compounds, this project studied the effects of various fertilizers (fresh cow manure, composted cow manure, and urea) on these insect-killing organisms. Results showed that S. carpocapsae is more active in soils with no fertilizer amendment or with composted manure than with fresh manure or chemical fertilizer; B. bassiana is adversely affected by fresh manure. Investigation of factors that may enhance dispersal (which in turn may be a determining factor in the success of biological control) found that dispersal of two species of insect-killing nematodes was increased in the presence of earthworms
The pain experience of Hispanic Americans: A critical literature review and conceptual model
Although the Hispanic population is a burgeoning ethnic group in the United States, little is known about their pain-related experience. To address this gap, we critically reviewed the existing literature on pain experience and management among Hispanic Americans (HAs). We focused our review on the literature on nonmalignant pain, pain behaviors, and pain treatment seeking among HAs. Pain management experiences were examined from HA patients' and health care providers' perspectives. Our literature search included variations of the term "Hispanic" with "AND pain" in PubMed, Embase, Web of Science, ScienceDirect, and PsycINFO databases. A total of 117 studies met our inclusion criteria. We organized the results into a conceptual model with separate categories for biological and/or psychological and sociocultural and/or systems-level influences on HAs' pain experience, response to pain, and seeking and receiving pain care. We also included information on health care providers' experience of treating HA patients with pain. For each category, we identified future areas of research. We conclude with a discussion of limitations and clinical implications.
PERSPECTIVE:
In this critical review of the literature we examined the pain and management experiences of the HA population. We propose a conceptual model, which highlights findings from the existing literature and future areas of research
Look, Think, Act: Using Critical Action Research to Sustain Reform in Complex Teaching/Learning Ecologies
This paper argues that educators interested in sustainability should look to complexity science for guiding principles. When we view our classrooms and campuses as living, dynamic ecologies, we can, as insiders, make sense of what might otherwise seem chaotic or meaningless. This perspective enables us not only to describe and explain what is happening around us, but also to use our findings to influence emerging patterns across our classrooms, campuses, or our larger communities. We suggest that educators use a Look, Think, Act cycle recommended by Ernie Stringer to encourage and support sustainable school reform
National Health Service healthcare staff experience and practices regarding complementary and alternative medicine: an online survey.
The use of complementary and alternative medicine (CAM) is increasing. The most common reported reason for CAM use is dissatisfaction with conventional healthcare. Several studies have reported factors influencing CAM usage and beliefs in the general public but the beliefs of healthcare staff are less well known. This paper reports the results of an online survey of 537 healthcare staff. Our study demonstrated an increased rate of patient referral for CAM from both personal CAM users and those trained in CAM. There was a high level of optimism amongst respondents as to the role CAM may play in patient care with mental health, depression and palliative care cited as the areas with highest expected benefit. Doctors were generally less optimistic about the likelihood of benefit compared to other healthcare staff. Implications for clinical practice, future research and staff education are discussed
Investigating the veracity of a sample of divergent published trial data in spinal pain
Evidence-based medicine is replete with studies assessing quality and bias, but few evaluating research integrity or trustworthiness. A recent Cochrane review of psychological interventions for chronic pain identified trials with a shared lead author with highly divergent results. We sought to systematically identify all similar trials from this author to explore their risk of bias, governance procedures, and trustworthiness. We searched OVID MEDLINE, EMBASE, CENTRAL, and PEDro from 2010 to December 22, 2021 for trials. We contacted the authors requesting details of trial registration, ethical approval, protocol, and access to the trial data for verification. We used the Cochrane risk-of-bias tool and the Cochrane Pregnancy and Childbirth group's Trustworthiness Screening Tool to guide systematic exploration of trustworthiness. Ten trials were included: 9 compared cognitive behavioural therapy and physical exercise to usual care, exercise alone, or physiotherapy and 1 compared 2 brief cognitive behavioural therapy programmes. Eight trials reported results divergent from the evidence base. Assessment of risk of bias and participant characteristics identified no substantial concerns. Responses from the lead author did not satisfactorily explain this divergence. Trustworthiness screening identified concerns about research governance, data plausibility at baseline, the results, and apparent data duplication. We discuss the findings within the context of methods for establishing the trustworthiness of research findings generally. Important concerns regarding the trustworthiness of these trials reduce our confidence in them. They should probably not be used to inform the results and conclusions of systematic reviews, in clinical training, policy documents, or any relevant instruction regarding adult chronic pain management
Changes in body weight and food choice in those attempting smoking cessation: a cluster randomised controlled trial
<p><b>Background:</b> Fear of weight gain is a barrier to smoking cessation and significant cause of relapse for many people. The provision of nutritional advice as part of a smoking cessation programme may assist some in smoking cessation and perhaps limit weight gain. The aim of this study was to determine the effect of a structured programme of dietary advice on weight change and food choice, in adults attempting smoking cessation.</p>
<p><b>Methods:</b> Cluster randomised controlled design. Classes randomised to intervention commenced a 24-week intervention, focussed on improving food choice and minimising weight gain. Classes randomised to control received "usual care".</p>
<p><b>Results:</b> Twenty-seven classes in Greater Glasgow were randomised between January and August 2008. Analysis, including those who continued to smoke, showed that actual weight gain and percentage weight gain was similar in both groups. Examination of data for those successful at giving up smoking showed greater mean weight gain in intervention subjects (3.9 (SD 3.1) vs. 2.7 (SD 3.7) kg). Between group differences were not significant (p=0.23, 95% CI -0.9 to 3.5). In comparison to baseline improved consumption of fruit and vegetables and breakfast cereal were reported in the intervention group. A higher percentage of control participants continued smoking (74% vs. 66%).</p>
<p><b>Conclusions:</b> The intervention was not successful at minimising weight gain in comparison to control but was successful in facilitating some sustained improvements in the dietary habits of intervention participants. Improved quit rates in the intervention group suggest that continued contact with advisors may have reduced anxieties regarding weight gain and encouraged cessation despite weight gain. Research should continue in this area as evidence suggests that the negative effects of obesity could outweigh the health benefits achieved through reductions in smoking prevalence.</p>
