A descriptive comparative study to determine a homoeopathic perspective on the human immunodeficiency virus in homosexual males

M. Tech.Since year zero of the HIV/AIDS pandemic, homosexuality has been linked to HIV/AIDS (Hooper; 2000). HIV positive homosexual individuals, therefore, are exposed to double stigmatisation; that of being homosexual and of being infected with HIV/AIDS. Taking into account the link between psyche, neural and immunological function, the above statement directly impacts the pathophysiology and prognosis of HIV/AIDS (Forrest and Kanbus; 2004) (De Kooker; 2002). This study examines the psychological and emotional states of the subjects, which are influenced, not only by their disease state but also by social stigmatisation. The aim of the study is to obtain a comprehensive homoeopathic symptom picture of HIV positive homosexual males within a South African context, compare this to existing homoeopathic symptom pictures, discuss HIV/AIDS in terms of miasmatic theory and consider possible homoeopathic treatment options for HIV/AIDS. This is a qualitative pilot study. Fourteen HIV positive homosexual males, of varying race, were recruited through Caritas Care and interviewed in Gauteng. The participants were between the ages of twenty and fifty and in stage one to three of HIV infection. Six of the participants were on antiretroviral therapy, eight not. The participants were interviewed using set questionnaires and underwent a physical examination. The interview transcripts were analysed and compared to each other then commonalities extracted to obtain a composite symptom picture. The composite symptom picture was compared to existing genus epidemicus symptom pictures and existing nosode proving pictures. The composite symptom picture was analysed using Cara Pro computerized repertorisation to determine possible treatment options. This computer programme affords the user access to multiple repertories simultaneously for rubric selection, and then analyses the case allowing for the use of different strategies. The composite symptom picture was also analysed in terms of miasmatic characteristics. The study concludes that the composite symptom picture partially matches existing HIV/AIDS genus epidemicus symptom pictures and nosode proving pictures. The composite symptom picture exhibits prominent themes of mental and emotional restlessness, generalized weakness, rebelliousness, desire for control and a desire for warmth. Possible treatment options are indicated. The include the remedies Sepia, Apis mellifica, Bryonia alba, Iodium and Natrum carbonicum but particularly of the Flouratum mineral group remedies such as Calcarea fluorica and Acidum flouricum. The study indicates that HIV/AIDS is emerging as a new miasm exhibiting characteristics of the Sycotic and Tuberculinic miasms.Dr. L. Solomon Dr. T. Blak

Health of War-Affected Karen Adults 5 Years Post-Resettlement

Background: An estimated 140 000 refugees from Burma have resettled to the USA since 2009, comprising 21% of total resettlement in the USA over the last decade. Our objective was to describe patterns of longitudinal health outcomes in a cohort of Karen refugees resettled in the USA for 5 years, and to translate these findings to a primary healthcare context. Methods: The study was a retrospective cohort study focused on the analysis of the first 5 years of electronic health records of a sample of 143 Karen refugees who were initially resettled between May 2011 and May 2013. Results: Through descriptive, inferential and survival statistics, we described patterns of retention in primary care, biometric trends, condition prevalence and survival probabilities. Highest prevalence health conditions documented at any point in the 5-year period included diagnoses or symptoms associated with pain (52%); gastrointestinal disturbance (41%); metabolic disorder (41%); infectious process (34%); mental health condition (31%) and central nervous system disorder (24%). Conclusions: This study is the first retrospective longitudinal analysis of patterns of health in Karen refugees originating from Burma and resettled to the USA. Findings identified in the 5-year, the post-resettlement period provided important clinical insights into the health trajectories of war-affected populations. Burden of illness was high although results did not demonstrate the extent of trauma-associated physical health conditions reported in the literature. Indicators such as significant increases in body mass index (BMI), the overall prevalence of dyslipidaemia and others suggested that the cohort may be exhibiting an early trajectory towards the development of these conditions. Authors summarize potential protective factors experienced by the cohort that promoted aspects of health frequently challenged in forced migration

Complexities and complications of extreme obesity

Obesity is a common chronic disorder and has detrimental long-term consequences if left untreated. Herein, we report a case of a young lady who suffered from morbid obesity and many of its consequences, and we present a literature review of these complications. While the cause of obesity is multifactorial, the genetic component is particularly important in the pathophysiology of marked obesity. Resistance to Leptin is considered one of the main causes of obesity. There is a unique relationship between polycystic ovary syndrome and obesity, as observed in our case. Obesity is associated with cardiovascular and lung diseases such as heart failure, thromboembolic disease, sleep apnea, and pulmonary hypertension. Our patient had cardiomegaly (730 gm) with eccentric hypertrophy of left and right ventricles. The coronary arteries and aorta were free of atherosclerosis, which is a surprising finding that relates to the mysterious phenomenon of obesity paradox. The terminal event in our young woman was multiple segmental and subsegmental pulmonary arterial thrombi/ thromboemboli superimposed on chronic cardiopulmonary stress due to massive obesity

From Process to Product: Your Risk Process at Work

The Space Life Sciences Directorate (SLSD) and Human Research Program (HRP) at the NASA/Johnson Space Center work together to address and manage the human health and performance risks associated with human space flight. This includes all human system requirements before, during, and after space flight, providing for research, and managing the risk of adverse long-term health outcomes for the crew. We previously described the framework and processes developed for identifying and managing these human system risks. The focus of this panel is to demonstrate how the implementation of the framework and associated processes has provided guidance in the management and communication of human system risks. The risks of early onset osteoporosis, CO2 exposure, and intracranial hypertension in particular have all benefitted from the processes developed for human system risk management. Moreover, we are continuing to develop capabilities, particularly in the area of information architecture, which will also be described. We are working to create a system whereby all risks and associated actions can be tracked and related to one another electronically. Such a system will enhance the management and communication capabilities for the human system risks, thereby increasing the benefit to researchers and flight surgeons

Using mobile sensing data to assess stress: Associations with perceived and lifetime stress, mental health, sleep, and inflammation

Background Although stress is a risk factor for mental and physical health problems, it can be difficult to assess, especially on a continual, non-invasive basis. Mobile sensing data, which are continuously collected from naturalistic smartphone use, may estimate exposure to acute and chronic stressors that have health-damaging effects. This initial validation study validated a mobile-sensing collection tool against assessments of perceived and lifetime stress, mental health, sleep duration, and inflammation. Methods Participants were 25 well-characterized healthy young adults (Mage = 20.64 years, SD = 2.74; 13 men, 12 women). We collected affective text language use with a custom smartphone keyboard. We assessed participants’ perceived and lifetime stress, depression and anxiety levels, sleep duration, and basal inflammatory activity (i.e. salivary C-reactive protein and interleukin-1β). Results Three measures of affective language (i.e. total positive words, total negative words, and total affective words) were strongly associated with lifetime stress exposure, and total negative words typed was related to fewer hours slept (all large effect sizes: r = 0.50 – 0.78). Total positive words, total negative words, and total affective words typed were also associated with higher perceived stress and lower salivary C-reactive protein levels (medium effect sizes; r = 0.22 – 0.32). Conclusions Data from this initial longitudinal validation study suggest that total and affective text use may be useful mobile sensing measures insofar as they are associated with several other stress, mental health, behavioral, and biological outcomes. This tool may thus help identify individuals at increased risk for stress-related health problems

Vascular reactivity is altered in the placentas of fetuses with congenital diaphragmatic hernia

Introduction: Infants with congenital diaphragmatic hernia (CDH) often develop pulmonary hypertension but frequently fail to respond to vasodilator therapy, for instance because of an altered pulmonary vasoreactivity. Investigating such alterations in vivo is impossible. We hypothesised that these alterations are also present in fetoplacental vessels, since both vasculatures are exposed to the same circulating factors (e.g. endothelin-1) and respond similarly to certain stimuli (e.g. hypoxia). As proof-of-concept, we compared fetoplacental vasoreactivity between healthy and CDH-affected placentas. Methods: Fetoplacental vascular function of healthy and antenatally diagnosed left-sided CDH fetuses was assessed by wire myography. Placental expression of enzymes and receptors involved in the altered vasoreactive pathways was measured using quantitative PCR. Results: CDH arteries (n = 6) constricted more strongly to thromboxane A2 agonist U46619 (p &lt; 0.001) and dilated less to bradykinin (p = 0.01) and nitric oxide (NO)-donor sodium nitroprusside (p = 0.04) than healthy arteries (n = 8). Vasodilation to prostacyclin analogue iloprost and adenylate cyclase stimulator forskolin, and vasoconstriction to endothelin-1 were not different between both groups. Angiotensin II did not induce vasoconstriction. Phosphodiesterase inhibitors sildenafil and milrinone did not affect responses to sodium nitroprusside, forskolin, or U46619. The mRNA expression of guanylate cyclase 1 soluble subunit alpha 1 (p = 0.003) and protein kinase cyclic guanine monophosphate (cGMP)-dependent 1 (p = 0.02) were reduced in CDH versus healthy placentas. Discussion: The identified changes in the thromboxane and NO-cGMP pathways in the fetoplacental vasculature correspond with currently described alterations in the pulmonary vasculature in CDH. Therefore, fetoplacental arteries may provide an opportunity to predict pulmonary therapeutic responses in infants with CDH.</p

Sustainable Agriculture Undergraduate Degree Programs: A Land-Grant University Mission

There has been considerable growth in the number undergraduate degree programs in sustainable agriculture (SA) in universities and colleges across the country in the past 25 years. As a subset of this national trend, land-grant universities (LGUs) are emerging as catalysts in innovative SA program development, in part due to the LGU tripartite mission of education, extension, and research. This mission compels LGUs to develop undergraduate degree offerings to engage student, faculty, and community stakeholders who are increasingly interested in SA. In this article, which is an outcome of a gathering of faculty, staff and students from SA programs at LGUs at a workshop prior to the 4th National Sustainable Agriculture Education Association Conference in August 2011, we discuss the justification for SA programming at LGUs, the emergence of SA major and minor degrees at 11 LGUs to date, the common successes and challenges of current SA programs, strategies for improving existing SA programming, and systematic approaches for expanding SA education impact across institutional lines. We also introduce several additional topic-based articles that resulted from workshop dialogue that appear in this issue of the Journal of Agriculture, Food Systems, and Community Development, including civic engagement efforts in SA education through community-university partnerships, a critical documentation of the implicit inclusion of values into SA education, and efforts to internationalize SA curriculum

Rat Long Chain Acyl-CoA Synthetase 5 Increases Fatty Acid Uptake and Partitioning to Cellular Triacylglycerol in McArdle-RH7777 Cells

Long chain acyl-CoA synthetase (ACSL) catalyzes the initial step in long chain fatty acid metabolism. Of the five mammalian ACSL isoforms cloned and characterized, ACSL5 is the only isoform found to be located, in part, on mitochondria and thus was hypothesized to be involved in fatty acid oxidation. To elucidate the specific roles of ACSL5 in fatty acid metabolism, we used adenoviral-mediated overexpression of ACSL5 (Ad-ACSL5) in rat hepatoma McArdle-RH7777 cells. Confocal microscopy revealed that Ad-ACSL5 colocalized to both mitochondria and endoplasmic reticulum. When compared with cells infected with Ad-GFP, Ad-ACSL5-infected cells at 24 h after infection had 2-fold higher acyl-CoA synthetase activities and 30% higher rates of fatty acid uptake when incubated with 500 microM [1-(14)C]oleic acid. Metabolism of [1-(14)C]oleic acid to cellular triacylglycerol (TAG) increased 42% in Ad-ACSL5-infected cells, but when compared with control cells, metabolism to acid-soluble metabolites, phospholipids, and medium TAG did not differ substantially. The incorporation of [1-(14)C]oleate and [1,2,3-(3)H]glycerol into TAG was similar in Ad-ACSL5-infected cells, thus indicating that Ad-ACSL5 increased TAG synthesis through both de novo and reacylation pathways. However, [1-(14)C]acetic acid incorporation into cellular lipids showed that, when compared with control cells, Ad-ACSL5-infected cells did not increase the metabolism of fatty acids that were derived from de novo synthesis. These results suggest that uptake of fatty acids into cells is regulated by metabolism and that overexpressed ACSL5 partitions exogenously derived fatty acids toward TAG synthesis and storage
