Backgrounding calves

"Backgrounding is the growing of steers and heifers from weaning until they enter the feedlot for finishing. It is suited to farmers who do not want to maintain a cow herd, do not want to finish cattle but do want to put added weight on calves after weaning."--First page.Homer B.

Backgrounding calves part 1 : assessing the opportunity (1993)

Backgrounding is the growing of steers and heifers from weaning until they enter the feedlot for finishing. It is suited to farmers who do not want to maintain a cow herd, do not want to finish cattle, but do want to put added weight on calves after weaning

Backgrounding calves part 2 : herd health and feeding (1993)

Backgrounding calves, or taking weaned calves at about 450 pounds and feeding them up to 750 pounds or so, is becoming more popular among cattle producers. It can be a profit maker for the producer who wants an alternative to the cow/calf business, wants to use excess forage or other roughages, has extra time during parts of the year, or wants to add flexibility to his current cattle operation

Backgrounding calves. Part 2. Herd health and feeding

"In Part 1 of this Agricultural Guide (number 2095) we discussed basic backgrounding strategies and compared profitability with other cattle enterprises. In this section, we will focus on herd health requirements and feeding for successful backgrounding. There are many animal health problems to consider, especially if you will be purchasing most or all of the calves to be backgrounded."--First page.Homer B.

Histories of violence among clients seeking substance use disorder treatment: a systematic mapping review

IntroductionThere is a limited literature base regarding the intersection of drug and alcohol treatment, violence, and trauma. While research substantiates that exposure to violence and trauma impacts the propensity to misuse substances, the conceptualization in clinical trials and practice has largely been narrow and gendered, referring only to intimate partner or domestic violence. Our systematic mapping review explored a more inclusive and expansive review of survivors of and perpetrators of violence and trauma (e.g., intimate partner violence, sexual assault, stalking, child abuse, political and community violence, criminal violence, micro violence, structural violence, and oppression) to establish: 1) the types of treatment settings included in intervention studies, 2) the common indicators of success or common outcomes recorded, and 3) understanding who is seeking treatment for drug and alcohol use with histories of violence.MethodsA systematic mapping review was conducted to identify any peer-reviewed articles published from 2011 to 2022. The Web of Science database was searched using a broad set of Boolean search terms related to violence, substance use disorders, and treatment. Over 8,800 records were identified from the systematic review with a total of 48 articles meeting inclusion criteria. ResultsMost studies in this review included populations reporting perpetration of violence (n=23, 48%) versus participants reporting survival of trauma/violence (n=17, 35%). Results also indicated female identifying populations (n=19; 40%) were predominantly served, were treated in the US (n=33; 69%) and seen in an outpatient setting (n=24; 50%). Authors also were attentive to studies that included sexual and gender minorities and discovered only three studies (6%) explicitly acknowledging inclusion of transgender participants or participants in relationship with partners of the same sex; three more studies (6%) were focused on participants with histories of or engaging in sex work. DiscussionThis review outlines treatment and research implications directly situated in the gap of service delivery found in this review. Specifically, the results elucidate the impact on minoritized and excluded identities based on gender, sexual preference, criminal legal status and directions for research and treatment to increase inclusion, representation, and equity across research and treatment settings

Nuclear Cryogenic Propulsion Stage

The fundamental capability of Nuclear Thermal Propulsion (NTP) is game changing for space exploration. A first generation Nuclear Cryogenic Propulsion Stage (NCPS) based on NTP could provide high thrust at a specific impulse above 900 s, roughly double that of state of the art chemical engines. Characteristics of fission and NTP indicate that useful first generation systems will provide a foundation for future systems with extremely high performance. The role of the NCPS in the development of advanced nuclear propulsion systems could be analogous to the role of the DC-3 in the development of advanced aviation. Progress made under the NCPS project could help enable both advanced NTP and advanced NEP

"They think we're OK and we know we're not". A qualitative study of asylum seekers' access, knowledge and views to health care in the UK

<i>Background</i>: The provision of healthcare for asylum seekers is a global issue. Providing appropriate and culturally sensitive services requires us to understand the barriers facing asylum seekers and the facilitators that help them access health care. Here, we report on two linked studies exploring these issues, along with the health care needs and beliefs of asylum seekers living in the UK. <i>Methods</i>: Two qualitative methods were employed: focus groups facilitated by members of the asylum seeking community and interviews, either one-to-one or in a group, conducted through an interpreter. Analysis was facilitated using the Framework method. <i>Results</i>: Most asylum seekers were registered with a GP, facilitated for some by an Asylum Support nurse. Many experienced difficulty getting timely appointments with their doctor, especially for self-limiting symptoms that they felt could become more serious, especially in children. Most were positive about the health care they received, although some commented on the lack of continuity. However, there was surprise and disappointment at the length of waiting times both for hospital appointments and when attending accident and emergency departments. Most had attended a dentist, but usually only when there was a clinical need. The provision of interpreters in primary care was generally good, although there was a tension between interpreters translating verbatim and acting as patient advocates. Access to interpreters in other settings, e.g. in-patient hospital stays, was problematic. Barriers included the cost of over-the-counter medication, e.g. children's paracetamol; knowledge of out-of-hours medical care; and access to specialists in secondary care. Most respondents came from countries with no system of primary medical care, which impacted on their expectations of the UK system. <i>Conclusion</i>: Most asylum seekers were positive about their experiences of health care. However, we have identified issues regarding their understanding of how the UK system works, in particular the role of general practitioners and referral to hospital specialists. The provision of an Asylum Support nurse was clearly a facilitator to accessing primary medical care. Initiatives to increase their awareness and understanding of the UK system would be beneficial. Interpreting services also need to be developed, in particular their role in secondary care and the development of the role of interpreter as patient advocate

Patient participation: A qualitative study of immigrant women and their experiences

Patient participation in healthcare is a neglected area of interest in the rather extensive amount of research on immigrant so-called Selma patients in Swedish health care as well as worldwide. The aim is to explore the phenomenon “patient participation” in the context of the Swedish health care from the perspective of immigrants non-fluent in Swedish. A phenomenological lifeworld approach was chosen. Data were collected from patients within a municipal home care setting in Sweden. Eight women agreed to participate. In seven interviews, an interpreter was necessary for the translation of the interview. Five authorized interpreters were used. Data were analysed in accordance to a descriptive phenomenological method for caring research. The analysis led to an essence of the phenomenon with three constituents, “to experience participation,” “to refrain from participation,” and “to be deprived of participation.” Patient participation from the perspective of immigrant women means that patients are involved and active in their own health and caring processes. For these women, it is particularly important to have the opportunity to express themselves. Patient participation presupposes professional caregivers who act in a way that increases the patients' opportunities to take part. A skilled interpreter is often necessary in order to enable the patient participation

Biomarkers of chemotherapy-induced cardiotoxicity: toward precision prevention using extracellular vesicles

Detrimental side effects of drugs like doxorubicin, which can cause cardiotoxicity, pose barriers for preventing cancer progression, or treating cancer early through molecular interception. Extracellular vesicles (EVs) are valued for their potential as biomarkers of human health, chemical and molecular carcinogenesis, and therapeutics to treat disease at the cellular level. EVs are released both during normal growth and in response to toxicity and cellular death, playing key roles in cellular communication. Consequently, EVs may hold promise as precision biomarkers and therapeutics to prevent or offset damaging off-target effects of chemotherapeutics. EVs have promise as biomarkers of impending cardiotoxicity induced by chemotherapies and as cardioprotective therapeutic agents. However, EVs can also mediate cardiotoxic cues, depending on the identity and past events of their parent cells. Understanding how EVs mediate signaling is critical toward implementing EVs as therapeutic agents to mitigate cardiotoxic effects of chemotherapies. For example, it remains unclear how mixtures of EV populations from cells exposed to toxins or undergoing different stages of cell death contribute to signaling across cardiac tissues. Here, we present our perspective on the outlook of EVs as future clinical tools to mitigate chemotherapy-induced cardiotoxicity, both as biomarkers of impending cardiotoxicity and as cardioprotective agents. Also, we discuss how heterogeneous mixtures of EVs and transient exposures to toxicants may add complexity to predicting outcomes of exogenously applied EVs. Elucidating how EV cargo and signaling properties change during dynamic cellular events may aid precision prevention of cardiotoxicity in anticancer treatments and development of safer chemotherapeutics
