Barriers and Opportunities for Sanitation and Water for All, as Envisaged by the New Delhi Statement
Today, 884 million people lack access to water and 2.6 billion lack access to sanitation. In the past 20 years, there has been important progress made in these areas at the international level. But despite some milestones, significant challenges remain to be addressed. Some of these milestones reflect recommendations from the New Delhi Statement, which endorsed the principle of ‘Some for All Rather than More for Some’, and its four guiding principles, 1 as do some of the remaining challenges. Other trends have emerged since then, as well. This article identifies the main political developments over the last 30 years and examines some barriers to the progress of attaining universal water and sanitation provision. It also outlines some of what we have done or not done in implementing the concepts contained in the New Delhi Statement, and identifies some key lessons for the future
Estimating background rates of Guillain-Barré Syndrome in Ontario in order to respond to safety concerns during pandemic H1N1/09 immunization campaign
Abstract
Background
The province of Ontario, Canada initiated mass immunization clinics with adjuvanted pandemic H1N1 influenza vaccine in October 2009. Due to the scale of the campaign, temporal associations with Guillain-Barré syndrome (GBS) and vaccination were expected. The objectives of this analysis were to estimate the number of background GBS cases expected to occur in the projected vaccinated population and to estimate the number of additional GBS cases which would be expected if an association with vaccination existed. The number of influenza-associated GBS cases was also determined.
Methods
Baseline incidence rates of GBS were determined from published Canadian studies and applied to projected vaccine coverage data to estimate the expected number of GBS cases in the vaccinated population. Assuming an association with vaccine existed, the number of additional cases of GBS expected was determined by applying the rates observed during the 1976 Swine Flu and 1992/1994 seasonal influenza campaigns in the United States. The number of influenza-associated GBS cases expected to occur during the vaccination campaign was determined based on risk estimates of GBS after influenza infection and provincial influenza infection rates using a combination of laboratory-confirmed cases and data from a seroprevalence study.
Results
The overall provincial vaccine coverage was estimated to be between 32% and 38%. Assuming 38% coverage, between 6 and 13 background cases of GBS were expected within this projected vaccinated cohort (assuming 32% coverage yielded between 5-11 background cases). An additional 6 or 42 cases would be expected if an association between GBS and influenza vaccine was observed (assuming 32% coverage yielded 5 or 35 additional cases); while up to 31 influenza-associated GBS cases could be expected to occur. In comparison, during the same period, only 7 cases of GBS were reported among vaccinated persons.
Conclusions
Our analyses do not suggest an increased number of GBS cases due to the vaccine. Awareness of expected rates of GBS is crucial when assessing adverse events following influenza immunization. Furthermore, since individuals with influenza infection are also at risk of developing GBS, they must be considered in such analyses, particularly if the vaccine campaign and disease are occurring concurrently
Physicians’ Perspectives on Prescribing Benzodiazepines for Older Adults: A Qualitative Study
BACKGROUND: There is a continued high prevalence of benzodiazepine use by older community-residing adults and of their continued prescription by practitioners, despite well known adverse effects and the availability of safer, effective alternatives. OBJECTIVES: To understand factors influencing chronic use of benzodiazepines in older adults. DESIGN: Qualitative study, semistructured interviews with physicians. PARTICIPANTS: Thirty-three practicing primary care physicians around Philadelphia. APPROACH: Qualitative interviews were audiotaped, transcribed, and entered into a qualitative software program. A multidisciplinary team coded transcripts and developed themes. RESULTS: Physicians generally endorsed benzodiazepines as effective treatment for anxiety, citing quick action and strong patient satisfaction. The use of benzodiazepines in older adults was not seen to be problematic because they did not show drug-seeking or escalating dose behavior suggesting addiction. Physicians minimized other risks of benzodiazepines and did not view monitoring or restricting renewal of prescriptions as an important clinical focus relative to higher-priority medical issues. Many physicians expressed skepticism about risks of continued use and considerable pessimism in the successful taper/discontinuation in older patients with long-term use and prior failed attempts. Physicians also anticipated patient resistance to any such efforts, including switching physicians. CONCLUSIONS: Primary care physicians are averse to addressing the public health problem of benzodiazepine overuse in the elderly. Their attitudes generally conflict with practice guidelines and they complain of a lack of training in constructive strategies to address this problem. A 2-pronged effort should focus on increasing skill level and preventing new cases of benzodiazepine dependency through improved patient education and vigilant monitoring of prescription renewal

Federal Agencies Have Stymied Access to Record Showing Impact of Texas-Mexico Border Wall
Federal officials are illegally withholding documents that would allow the public to determine the full impact of the 700 miles of fence being built along the Texas-Mexico border, Public Citizen argued in a suit filed in U.S. district court today on behalf of a member of the University of Texas (UT) Working Group on Human Rights and the Border Wall.UT Librarie
