Prevalence of occupational heat stress across the seasons and its management amongst healthcare professionals in the UK.

Occupational heat stress (OHS) is an issue in healthcare facilities (HCFs) in the United Kingdom (UK). The aims of this study were to evaluate perceived levels of OHS during two seasons and its perceived consequences on healthcare professionals (HCPs) and to assess the efficacy of heat stress management (HSM) policies. An anonymous online survey was distributed to HCPs working in HCFs in the UK. The survey returned 1014 responses (87% women). Descriptive statistics and content analysis of survey data identified that OHS in HCFs is frequently experienced throughout the year and concerned most HCPs. Over 90% perceived OHS impairs their performance and 20% reported heat-related absenteeism. Awareness of HSM policies was poor and 73% deemed them not adequate. To help reduce the financial loss and impact on staff performance, health and well-being and patient safety, it is recommended that revisions and widespread dissemination of HSM policies are made.

International consensus (ICON) on basic voice assessment for unilateral vocal fold paralysis.

There is a growing need for evaluation tools allowing the quantification of the outcome after voice surgeries. Since the end of the 1990s, multiple unfruitful attempts have been made to reach a consensus, including the Dejonckere protocol for the European Laryngological Society in 2001. This suggested to perform objective and quantifiable measures in the following domains: perception, acoustic, aerodynamic, self-evaluation by the patient and videolaryngostroboscopy. But in a PubMed® search with the keywords "Voice Assessment" and "Voice Outcome" since 2001 retrieving 452 articles, only 33 of them were using methods taking into account the first four dimensions proposed by Dejonckere. To elaborate a new and simpler protocol, we chose to focus on unilateral vocal fold paralyses (UVFP), which represents a homogeneous disease in terms of physiology. This protocol was elaborated on the basis of a review of the literature and of the database and experience of the IFOS panel members. In summary, our group recommends the use and implementation of the ELS "basic protocol" with some minor modifications. Voice audio recordings are an indispensable prerequisite, and may even have medico-legal implications. We recommend the systematic use of the Voice Handicap Index (VHI). Perceptual analysis must be performed by using Hirano's GRB scale and voice breathiness has to be prioritized. Currently, acoustic analysis remains optional given the lack of data to support clinical usefulness. Aerodynamic studies should include at a minimum an evaluation of the Maximum Phonation Time, calculated in seconds following multiple trials in order to obtain a recording representing the patient's best possible glottis closure.

Measured versus estimated energy expenditure in mechanically ventilated critically ill patients.

Accurate determination of energy expenditure is essential in patients receiving nutritional support to meet metabolic needs. The purpose of this study was to assess and compare the energy expenditure as measured by indirect calorimetry (MEE) and estimated by 5 equations in the mechanically ventilated critically ill patients. Forty-six patients were divided into either enteral nutrition (EN) (n=l2), total parenteral nutrition (TPN) (n=16) or combined (EN plus TPN) (n=l8) groups. Patients' energy expenditure was measured by indirect calorimetry on two occasions. Anthropometric and biochemical measurements, energy expenditure and medical status (APACHE II score) were also assessed in the intensive care unit (ICU) of Taichung Veteran General hospital. No significant difference was found in the MEE among the 3 groups. The type of nutritional support did not affect MEE. Energy expenditure calculated by using Harris- Benedict, Kleiber and Liu equations times the estimated stress factor did not significantly different than the values of MEE in all groups. There were significant correlations (P<0.01) between MEE and patients' sex (r=-0.499), age (r=-0.402), height (r=0.533), knee height (r=0.431), current body weight (r=0.379), usual body weight (r=0.407), ideal body weight (r=0.466) and urinary urea nitrogen (r=0.383) in the pooled group. Results demonstrated that energy expenditure could be estimated in most critically ill patients by using Harris-Benedict, Kleiber and Liu equations if the estimated stress factor is in the reasonable value.

Interim report of the Presidential Commission on the Human Immunodeficiency Virus Epidemic: Chairman's recommendations--Part I.

PIP: The Presidential Commission was created in September 1987 with the mandate to advise the White House "on the public health dangers including the medical, legal, ethical, social, and economic impact, from the spread of the HIV and resulting illnesses including AIDS, AIDS related complex, and other related conditions." This paper covers the Commission's interim policy recommendations as of March 15, 1988, in the areas of intravenous drug abuse, patient care, and basic research and drug development. The scope of recommendations in the area of intravenous drug abuse includes provision of treatment services, treatment research, drug abuse prevention, and outreach education. There must be a national policy of "treatment on demand" for drug users. An expanded program of drug treatment research must include research on cocaine as well as heroin addiction treatment. Drug abuse prevention should coordinate efforts at all levels of government as well as community and religious organizations and schools. Outreach education, which is especially difficult with drug users because drug use is illegal, will cost roughly $126.5 million a year over current funding. Outreach programs should train and utilize street outreach workers, including former addicts, and should have special focuses on adolescents, minorities, and women of childbearing age. The scope of recommendations in the area of patient care includes health care provider education, health care systems, psychosocial needs, nursing care, minorities and underserved populations, and information coordination and exchange. AIDS needs to be integrated into the educational curricula of medical and all other health professional schools. In the area of health care systems, the recommendations emphasize the need for integrated community-based services for people with HIV infection. 22 AIDS Service Delivery Demonstration projects are currently being conducted in the US, 13 funded by the US Public Health Service and 9 funded by the Robert Wood Johnson Foundation.^ieng
