Paediatric mortality related to pandemic influenza A H1N1 infection in England: an observational population-based study.

BACKGROUND: Young people (aged 0-18 years) have been disproportionately affected by pandemic influenza A H1N1 infection. We aimed to analyse paediatric mortality to inform clinical and public health policies for future influenza seasons and pandemics. METHODS: All paediatric deaths related to pandemic influenza A H1N1 infection from June 26, 2009, to March 22, 2010 in England were identified through daily reporting systems and cross-checking of records and were validated by confirmation of influenza infection by laboratory results or death certificates. Clinicians responsible for each individual child provided detailed information about past medical history, presentation, and clinical course of the acute illness. Case estimates of influenza A H1N1 were obtained from the Health Protection Agency. The primary outcome measures were population mortality rates and case-fatality rates. FINDINGS: 70 paediatric deaths related to pandemic influenza A H1N1 were reported. Childhood mortality rate was 6 per million population. The rate was highest for children aged less than 1 year. Mortality rates were higher for Bangladeshi children (47 deaths per million population [95% CI 17-103]) and Pakistani children (36 deaths per million population [18-64]) than for white British children (4 deaths per million [3-6]). 15 (21%) children who died were previously healthy; 45 (64%) had severe pre-existing disorders. The highest age-standardised mortality rate for a pre-existing disorder was for chronic neurological disease (1536 per million population). 19 (27%) deaths occurred before inpatient admission. Children in this subgroup were significantly more likely to have been healthy or had only mild pre-existing disorders than those who died after admission (p=0·0109). Overall, 45 (64%) children had received oseltamivir: seven within 48 h of symptom onset. INTERPRETATION: Vaccination priority should be for children at increased risk of severe illness or death from influenza. This group might include those with specified pre-existing disorders and those in some ethnic minority groups. Early pre-hospital supportive and therapeutic care is also important.

Defining the Pedagogical Parameters of Islamic Bioethics

Secular bioethics has only recently begun to take religious perspectives seriously. Religion and Medicine courses in a number of universities across North America have incorporated Christian and Jewish perspectives for some time now, but Islamic, Buddhist and Hindu perspectives are only now gaining recognition. This late inclusion of Islamic perspectives can be partially attributed to the lack of materials in English on Islamic bioethics. Moreover, those materials that have been published actually deal with juridical-religious opinions rather than ethical deliberations based on principles and rules as developed in Islamic legal sciences. Here and there in these writings one reads references to the principle of “public interest” (maslaha), without any elucidation about its function, either as a principle in legal theory or as a rule of utility or beneficence that promotes the good in ethical decision-making. Instead, we have a plethora of juridical opinions (fatawa, plural of fatwa) deduced from the revealed texts on issues in biomedicine like abortion, end of life decisions, and more recently, genetic engineering or stem cell research, without any ethical discussion on the rightness or wrongness of the act in its medical scientific and clinical practical settings

Damping acoustic pressure pulsations in pipelines using Helmholtz resonators

In industrial piping systems, centrifugal and reciprocating turbomachinery generate acoustic pressure pulsations, which propagate into the pipeline and interact with piping components, potentially causing vibrations, increased fretting wear, and even fatigue failure. In this thesis, an acoustic damping device known as the Helmholtz resonator (HR) is experimentally studied. The effects of HR cavity volume, pipeline diameter, HR location, the use of multiple HRs, and mean flow velocity are investigated to determine their effects on the acoustic attenuation achieved within a pipeline. Measurements are also performed to clarify the mechanism of attenuation and the effects of incident pressure amplitude on the transmission loss of an HR. The findings of this thesis may be used as practical guidelines for the use of HRs in industrial systems, where characterizing the acoustics is usually difficult and costly, and the available space for damping devices may be limited

Religious perspectives on human suffering: Implications for medicine and bioethics

The prevention and relief of suffering has long been a core medical concern. But while this is a laudable goal, some question whether medicine can, or should, aim for a world without pain, sadness, anxiety, despair or uncertainty. To explore these issues, we invited experts from six of the world’s major faith traditions to address the following question. Is there value in suffering? And is something lost in the prevention and/or relief of suffering? While each of the perspectives provided maintains that suffering should be alleviated and that medicine’s proper role is to prevent and relieve suffering by ethical means, it is also apparent that questions regarding the meaning and value of suffering are beyond the realm of medicine. These perspectives suggest that medicine and bioethics has much to gain from respectful consideration of religious discourse surrounding suffering. Keywords Suffering; religion; medicine; bioethic

Religious perspectives on umbilical cord blood banking

Umbilical cord blood is a valuable source of haematopoietic stem cells. There is little information about whether religious affiliations have any bearing on attitudes to and decisions about its collection, donation and storage. The authors provided information about umbilical cord blood banking to expert commentators from six major world religions (Catholicism, Anglicanism, Islam, Judaism, Hinduism and Buddhism) and asked them to address a specific set of questions in a commentary. The commentaries suggest there is considerable support for umbilical cord blood banking in these religions. Four commentaries provide moral grounds for favouring public donation over private storage. None attach any particular religious significance to the umbilical cord or to the blood within it, nor place restrictions on the ethnicity or religion of donors and recipients. Views on ownership of umbilical cord blood vary. The authors offer a series of general points for those who seek a better understanding of religious perspectives on umbilical cord blood banking

Clinical characteristics and outcomes among pediatric patients hospitalized with pandemic influenza A/H1N1 2009 infection

PurposeThe purpose of this article is to describe the clinical and epidemiologic features and outcomes among children hospitalized with pandemic influenza A/H1N1 2009 infection.MethodsWe retrospectively reviewed the charts of hospitalized pediatric patients (<18 years) diagnosed with pandemic influenza A/H1N1 2009 infection by reverse-transcriptase polymerase chain reaction at a tertiary hospital in Seoul, Korea, between September 2009 and February 2010.ResultsA total of 72 children were hospitalized with pandemic influenza A/H1N1 2009 infection (median age, 6.0 years; range, 2 months to 18 years). A total of 40% had at least 1 underlying medical condition, including asthma (17%), malignancies (19%), and heart diseases (17%). Of the 72 patients, 54 (76%) children admitted with H1N1 infection showed radiographic alterations compatible with pneumonia. There was no significant difference in pre-existing conditions between pandemic influenza A/H1N1 infected patients with or without pneumonia. Children with pandemic influenza A/H1N1 pneumonia were more likely to have a lower lymphocyte ratio (P=0.02), higher platelet count (P=0.02), and higher level of serum glucose (P=0.003), and more commonly presented with dyspnea than did those without pneumonia (P=0.04).ConclusionNo significant differences in age, sex, or presence of preexisting conditions were found between children hospitalized with pandemic influenza A/H1N1 H1N1 influenza infection with pneumonia and those without pneumonia. Higher leukocyte count, higher glucose level, and a lower lymphocyte ratio were associated with the development of pandemic A/H1N1 2009 influenza pneumonia
