How a Departure From Free-market Principles Contributed to the Current Economic Downturn

What should the role of government be in regulating the economy? Through this paper the reader will gain an understanding of the impact of government intervention, when intervention is justified, and what happens when the government over regulates. The research will also reveal some major similarities between today’s economic downturn and the financial debacle of the Great Depression. Finally, analysis will show that, as a result of this unnecessary government intervention, that there is a crisis that is not solely American, but one that has become a major contributor to the global downturn

HIV testing among pregnant women living with HIV in India: are private healthcare providers routinely violating women’s human rights?

Background In India, approximately 49,000 women living with HIV become pregnant and deliver each year. While the government of India has made progress increasing the availability of prevention of mother-to-child transmission of HIV (PMTCT) services, only about one quarter of pregnant women received an HIV test in 2010, and about one-in-five that were found positive for HIV received interventions to prevent vertical transmission of HIV. Methods Between February 2012 to March 2013, 14 HIV-positive women who had recently delivered a baby were recruited from HIV positive women support groups, Government of India Integrated Counseling and Testing Centers, and nongovernmental organizations in Mysore and Pune, India. In-depth interviews were conducted to examine their general experiences with antenatal healthcare; specific experiences around HIV counseling and testing; and perceptions about their care and follow-up treatment. Data were analyzed thematically using the human rights framework for HIV testing adopted by the United Nations and India’s National AIDS Control Organization. Results While all of the HIV-positive women in the study received HIV and PMTCT services at a government hospital or antiretroviral therapy center, almost all reported attending a private clinic or hospital at some point in their pregnancy. According to the participants, HIV testing often occurred without consent; there was little privacy; breaches of confidentiality were commonplace; and denial of medical treatment occurred routinely. Among women living with HIV in this study, violations of their human rights occurred more commonly in private rather than public healthcare settings. Conclusions There is an urgent need for capacity building among private healthcare providers to improve standards of practice with regard to informed consent process, HIV testing, patient confidentiality, treatment, and referral of pregnant women living with HIV

Barriers to effective healthcare for patients who have smell or taste disorders

Objectives: Smell/taste disturbances are a common but underrated, under-researched and under treated sensory loss and an independent risk factor for reduced longevity. This study aimed to characterise the experience of patients with these disorders in seeking help. Design: The study was designed by patients together with clinicians through a dedicated workshop and conducted as a cross-sectional survey to capture experiences in public and private healthcare settings internationally. Setting: Primary, secondary and tertiary care. Participants: Any members of the public self-reporting a smell/taste disorder were invited to participate. Main outcome measures: The survey captured information including experience of getting consultations and referrals to medical professionals, treatments offered, costs incurred and related problems with mental health. Results: Of 673 participants; 510 female, 160 male, 3 not stated, self-reported aetiology included sinonasal disease (24%), idiopathic (24%) and post-viral olfactory dysfunction (22%); true gustatory disorders were typically rare. Failure of medical professionals to recognise the problem was a key concern - 64%, 76% and 47% of GPs, ENT specialists and Neurologists acknowledged respectively. Other issues included repeated ineffective treatments, difficulties getting referrals to secondary/tertiary care, mental health problems (60%) and a mean personal cost of £421 to seeking advice and treatment. Whilst the participants were self-selecting, however they do represent those who are seeking help and intervention for their disorders. Conclusion: There is an unmet need for these patients in accessing healthcare including a clear need to improve education of and engagement with the medical profession in Otorhinolaryngology, General Practice and other specialties, in order to remove the current barriers they face

The Burden of Revision Sinonasal Surgery in the UK – Data from the Chronic Rhinosinusitis Epidemiology Study (CRES); a cross sectional study

Objectives/Hypothesis The aim of this study was to investigate the surgical revision rate in patients with Chronic Rhinosinusitis (CRS) in the UK CRS Epidemiology Study (CRES). Previous evidence from national Sinonasal Audit showed that 1459 CRS patients demonstrated a surgical revision rate 19.1% at 5 years, with highest rates seen in those with polyps (20.6%). Setting Thirty secondary care centres around the UK. Participants A total of 221 controls and 1249 patients with CRS were recruited to the study including those with polyps (CRSwNPs), without polyps (CRSsNPs) and with allergic fungal rhinosinusitis (AFRS). Interventions Self-administered questionnaire. Primary outcome measure The need for previous sinonasal surgery. Results A total of 651 patients with CRSwNPs, 553 with CRSsNPs and 45 with AFRS were included. A total of 396 (57%) of patients with CRSwNPs/AFRS reported having undergone previous endoscopic nasal polypectomy (ENP), of which 182 of the 396 (46%) reported having received more than one operation. The mean number of previous surgeries per patient in the revision group was 3.3 (range 2 to 30) and a mean duration of time of 10 years since the last procedure. The average length of time since their first operation up to inclusion in the study was 15.5 years (range 0-74). Only 27.9% of all patients reporting a prior ENP had received concurrent endoscopic sinus surgery (ESS) (n=102). For comparison, surgical rates in patients with CRSsNPs were significantly lower; 13% of cases specifically reported ESS and of those only 30% reported multiple procedures (chi-squared p < 0.001). Conclusions This study demonstrated there is a high burden of both primary and revision surgery in patients with CRS, worst in those with AFRS and least in those with CRSsNPs. The burden of revision surgery appears unchanged in the decade since the Sinonasal Audit

CHronic Rhinosinusitis Outcome MEasures (CHROME), developing a core outcome set for trials of interventions in chronic rhinosinusitis

Statement of Problem: Evaluating the effectiveness of treatments in chronic rhinosinusitis (CRS) have been limited by both a paucity of high quality randomised trials, and the heterogeneity of outcomes in those that have been reported. Core outcome sets (COS) are an agreed, standardized set of outcomes that should be measured and reported by future trials as a minimum and will facilitate future meta-analysis of trial results in systematic reviews (SRs). We set out to develop a core outcome set for interventions for adults with CRS. Method(s) of study: A long-list of potential outcomes was identified by a steering group utilising a literature review, thematic analysis of a wide range of stakeholders’ views and systematic analysis of currently available Patient Reported Outcome Measures (PROMs). A subsequent e-Delphi process allowed 110 patients and healthcare practitioners to individually rate the outcomes in terms of importance, on a Likert scale. Main Results: After 2 rounds of the iterative Delphi process, the 54 initial outcomes were distilled down to a final core-outcome set of 15 items, over 4 domains. Principal Conclusions: The authors hope inclusion of these core outcomes in future trials will increase the value of research on interventions for CRS in adults. It was felt important to make recommendations regarding how these outcomes should be measured, although additional work is now required to further develop and revalidate existing outcome measures

Exploring the association between ingestion of foods with higher potential salicylate content and symptom exacerbation in chronic rhinosinusitis:Data from the National Chronic Rhinosinusitis Epidemiology Study

INTRODUCTION: Pharmacological salicylates are known to trigger respiratory exacerbations in patients with Non-Steroidal Exacerbated Respiratory Disease (N-ERD), a specific phenotype of Chronic Rhinosinusitis (CRS) and asthma. The impact of dietary sources of salicylates across subgroups of CRS is not well understood. The hypothesis is that in patients with nasal polyps present, there is likely to be a higher incidence of symptom exacerbation due to dietary salicylates regardless of any known response to pharmacological salicylate. METHODS: The Chronic Rhinosinusitis Epidemiology Study (CRES) was a questionnaire-based case-control study which sought to characterise the UK CRS population in terms of sociological, economic and medical factors. Using specific questions to examine participant responses relating to symptom exacerbation from food groups thought to be high in salicylate content, this analysis of the CRES database sought to compare an estimate of the prevalence of dietary sensitivity due to food with higher potential salicylate content across patients with CRS with (CRSwNPs) and without nasal polyposis (CRSsNPs) and with allergic fungal rhinosinusitis (AFRS). RESULTS: The CRSwNPs group were significantly more likely than controls to report symptom exacerbation due to ingestion of food groups with higher potential dietary salicylate content. The same trend was observed amongst CRSsNPs participants to a lesser degree. Reported response to the individual specific food groups wine, nuts, spicy foods, fruit and vegetables demonstrated that a statistically significant proportion of CRSwNPs and AFRS participants reported sensitivity to wine. CONCLUSIONS: This analysis suggests that there is an association between symptom exacerbation in response to food products with higher potential salicylate content, specifically wine, in CRS patients both with and without nasal polyposis when compared to controls, but especially in the CRSwNPs and AFRS phenotypes. Further studies are needed to detail if this relationship represents a causal relationship to dietary salicylate. The data present the possibility that a wider group of CRS patients may elicit salicylate sensitivity than those with known N-ERD

Evaluation of smoking as a modifying factor in chronic rhinosinusitis

Importance: The negative association of smoking with the respiratory tract is well known; however, the association between smoking and chronic rhinosinusitis (CRS) has not been well characterized. Objective: To analyze whether active smoking was a risk factor for CRS development, smoking was associated with disease-specific quality of life, and smokers experience an increased symptom burden than nonsmokers.  Design, Setting, and Participants: This subanalysis of the Chronic Rhinosinusitis Epidemiology Study (CRES), a prospective, questionnaire-based case-control study conducted between October 2007 and September 2013 was conducted across 30 UK tertiary/secondary care sites. Participants were identified at ear, nose, and throat outpatient clinics and classified into CRS phenotypes as per European Position Paper on Rhinosinusitis and Nasal Polyps 2012 criteria. The overall response rate of those identified to take part in the study was 66%. A total of 1535 questionnaires were returned, with 1470 considered eligible for inclusion. Data analysis was conducted in January 2020.  Main Outcomes and Measures: The CRES was designed to distinguish differences in socioeconomic status, geography, medical comorbidities, lifestyle, and quality of life between patients with CRS and healthy controls.  Results: A total of 1450 patients completed the smoking question, comprising 219 controls (15.1%; mean [SD] age, 47.3 [14.9] years; 143 women [68%]), 546 participants with CRS (37.7%; mean [SD] age, 51.8 [15.3] years; 259 women [53%]) without nasal polyps (CRSsNPs), and 685 participants (47.2%; mean [SD] age, 56.0 [14.5] years; 204 women [33%]) with CRS and nasal polyps/allergic fungal rhinosinusitis (CRSwNPs+). The mean age was similar, with a greater female preponderance in the control group and male in the CRSwNP group. The greatest number of active smokers was found among control participants (33 [15%]), with a lower rate of smokers in the patients with CRSwNPs+ (9.9%) and CRSsNPs (13.9%), respectively. We found a clinically significant difference in the mean difference in Sino-nasal Outcome Test (SNOT-22) scores between active smokers and nonsmokers for both CRS phenotypes (4.49, 12.25). In both CRS subgroups active smokers had significantly worse SNOT-22 scores than nonsmokers by a mean (SD) magnitude of 10 (18.99, 24.14) points. Nonsmokers also demonstrated a higher percentage of surgical procedures (1 or more), although this was not clinically or statistically different (0.34, 1.10).  Conclusions and Relevance: This questionnaire-based case-control study demonstrated a clinically significant symptom burden associated with active cigarette smoking, with worse SNOT-22 scores in the smoking cohort by a mean magnitude of 10 points. We could find no demonstrable evidence that smoking increases the likelihood of need for revision sinus surgery. Clinicians should encourage smoking cessation alongside general CRS medical management

MESSENGER observations of induced magnetic fields in Mercury's core

Orbital data from the Magnetometer on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft allow investigation of magnetic fields induced at the top of Mercury's core by time‐varying magnetospheric fields. We used 15 Mercury years of observations of the magnetopause position as well as the magnetic field inside the magnetosphere to establish the presence and magnitude of an annual induction signal. Our results indicate an annual change in the internal axial dipole term, g10, of 7.5 to 9.5 nT. For negligible mantle conductivity, the average annual induction signal provides an estimate of Mercury's core radius to within ±90 km, independent of geodetic results. Larger induction signals during extreme events are expected but are challenging to identify because of reconnection‐driven erosion. Our results indicate that the magnetopause reaches the dayside planetary surface 1.5–4% of the time

Modular model for Mercury's magnetospheric magnetic field confined within the average observed magnetopause

Accurate knowledge of Mercury's magnetospheric magnetic field is required to understand the sources of the planet's internal field. We present the first model of Mercury's magnetospheric magnetic field confined within a magnetopause shape derived from Magnetometer observations by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft. The field of internal origin is approximated by a dipole of magnitude 190 nT RM 3, where RM is Mercury's radius, offset northward by 479 km along the spin axis. External field sources include currents flowing on the magnetopause boundary and in the cross‐tail current sheet. The cross‐tail current is described by a disk‐shaped current near the planet and a sheet current at larger (≳ 5 RM ) antisunward distances. The tail currents are constrained by minimizing the root‐mean‐square (RMS) residual between the model and the magnetic field observed within the magnetosphere. The magnetopause current contributions are derived by shielding the field of each module external to the magnetopause by minimizing the RMS normal component of the magnetic field at the magnetopause. The new model yields improvements over the previously developed paraboloid model in regions that are close to the magnetopause and the nightside magnetic equatorial plane. Magnetic field residuals remain that are distributed systematically over large areas and vary monotonically with magnetic activity. Further advances in empirical descriptions of Mercury's magnetospheric external field will need to account for the dependence of the tail and magnetopause currents on magnetic activity and additional sources within the magnetosphere associated with Birkeland currents and plasma distributions near the dayside magnetopause

Ethical considerations for HIV cure-related research at the end of life

Abstract Background The U.S. National Institute of Allergies and Infectious Diseases (NIAID) and the National Institute of Mental Health (NIMH) have a new research priority: inclusion of terminally ill persons living with HIV (PLWHIV) in HIV cure-related research. For example, the Last Gift is a clinical research study at the University of California San Diego (UCSD) for PLWHIV who have a terminal illness, with a prognosis of less than 6 months. Discussion As end-of-life (EOL) HIV cure research is relatively new, the scientific community has a timely opportunity to examine the related ethical challenges. Following an extensive review of the EOL and HIV cure research ethics literature, combined with deliberation from various stakeholders (biomedical researchers, PLWHIV, bioethicists, and socio-behavioral scientists) and our experience with the Last Gift study to date, we outline considerations to ensure that such research with terminally ill PLWHIV remains ethical, focusing on five topics: 1) protecting autonomy through informed consent, 2) avoiding exploitation and fostering altruism, 3) maintaining a favorable benefits/risks balance, 4) safeguarding against vulnerability through patient-participant centeredness, and 5) ensuring the acceptance of next-of-kin/loved ones and community stakeholders. Conclusion EOL HIV cure-related research can be performed ethically and effectively by anticipating key issues that may arise. While not unique to the fields of EOL or HIV cure-related research, the considerations highlighted can help us support a new research approach. We must honor the lives of PLWHIV whose involvement in research can provide the knowledge needed to achieve the dream of making HIV infection curable
