PURPOSE: To assess unresolved parental grief, the associated long-term impact on mental and physical health, and health service use. PATIENTS AND METHODS: This anonymous, mail-in questionnaire study was performed as a population-based investigation in Sweden between August 2001 and October 2001. Four hundred forty-nine parents who lost a child as a result of cancer 4 to 9 years earlier completed the survey (response rate, 80%). One hundred ninety-one (43%) of the bereaved parents were fathers, and 251 (56%) were mothers. Bereaved parents were asked whether or not, and to what extent, they had worked through their grief. They were also asked about their physical and psychological well-being. For outcomes of interest, we report relative risk (RR) with 95% CIs as well as unadjusted odds ratios and adjusted odds ratios. RESULTS: Parents with unresolved grief reported significantly worsening psychological health (fathers: RR, 3.6; 95% CI, 2.0 to 6.4; mothers: RR, 2.9; 95% CI, 1.9 to 4.4) and physical health (fathers: RR, 2.8; 95% CI, 1.8 to 4.4; mothers: RR, 2.3; 95% CI, 1.6 to 3.3) compared with those who had worked through their grief. Fathers with unresolved grief also displayed a significantly higher risk of sleep difficulties (RR, 6.7; 95% CI, 2.5 to 17.8). Mothers, however, reported increased visits with physicians during the previous 5 years (RR, 1.7; 95% CI, 1.1 to 2.6) as well as a greater likelihood of taking sick leave when they had not worked through their grief (RR, 2.1; 95% CI, 1.2 to 3.5). CONCLUSION: Parents who have not worked through their grief are at increased risk of long-term mental and physical morbidity, increased health service use, and increased sick leave.

Allergic reactions to drugs are a serious public health concern. In 2013, the Division of Allergy, Immunology, and Transplantation of the National Institute of Allergy and Infectious Diseases sponsored a workshop on drug allergy. International experts in the field of drug allergy with backgrounds in allergy, immunology, infectious diseases, dermatology, clinical pharmacology, and pharmacogenomics discussed the current state of drug allergy research. These experts were joined by representatives from several National Institutes of Health institutes and the US Food and Drug Administration. The participants identified important advances that make new research directions feasible and made suggestions for research priorities and for development of infrastructure to advance our knowledge of the mechanisms, diagnosis, management, and prevention of drug allergy. The workshop summary and recommendations are presented herein.

Few studies have investigated causal pathways linking psychosocial factors to each other and to screening mammography. Conflicting hypotheses exist in the theoretic literature regarding the role and importance of subjective norms, a person's perceived social pressure to perform the behavior and his/her motivation to comply. The Theory of Reasoned Action (TRA) hypothesizes that subjective norms directly affect intention; while the Transtheoretical Model (TTM) hypothesizes that attitudes mediate the influence of subjective norms on stage of change. No one has examined which hypothesis best predicts the effect of subjective norms on mammography intention and stage of change. Two statistical methods are available for testing mediation, sequential regression analysis (SRA) and latent variable structural equation modeling (LVSEM); however, software to apply LVSEM to dichotomous variables like intention has only recently become available. No one has compared the methods to determine whether or not they yield similar results for dichotomous variables. ^ Study objectives were to: (1) determine whether the effect of subjective norms on mammography intention and stage of change are mediated by pros and cons; and (2) compare mediation results from the SRA and LVSEM approaches when the outcome is dichotomous. We conducted a secondary analysis of data from a national sample of women veterans enrolled in Project H.O.M.E. (H&barbelow;ealthy O&barbelow;utlook on the M&barbelow;ammography E&barbelow;xperience), a behavioral intervention trial. ^ Results showed that the TTM model described the causal pathways better than the TRA one; however, we found support for only one of the TTM causal mechanisms. Cons was the sole mediator. The mediated effect of subjective norms on intention and stage of change by cons was very small. These findings suggest that interventionists focus their efforts on reducing negative attitudes toward mammography when resources are limited. ^ Both the SRA and LVSEM methods provided evidence for complete mediation, and the direction, magnitude, and standard errors of the parameter estimates were very similar. Because SRA parameter estimates were not biased toward the null, we can probably assume negligible measurement error in the independent and mediator variables. Simulation studies are needed to further our understanding of how these two methods perform under different data conditions. ^

A national sample of family physicians was surveyed to (1) assess family physicians' beliefs about the human immunodeficiency virus (HIV) and individuals at risk for infection, their clinical competence regarding HIV-related issues, and their experiences with HIV disease; (2) present conclusions to the American Academy of Family Physicians (AAFP) to effect the development of an early clinical care protocol and a continuing medical education curriculum; and (3) collect base-line data for use in the evaluation of an early clinical care protocol and a continuing medical education curriculum, in the case that such programs are developed and disseminated. After considering retired or deceased respondents, of the 2,660 physicians surveyed, 1,678 (63.7%) responded. The resulting sample was representative of the active members of the AAFP. About 77% of the respondents were unable to accurately identify the universal precautions for blood and body fluids to prevent occupational transmission of HIV or hepatitis B virus (HBV). Residency trained and board certified physicians expressed fewer "external constraints," such as fear of losing patients, obviating them from providing treatment to individuals with HIV disease (p =.004 and p $<$.001, respectively). These physicians also manifested fewer "internal constraints" to the provision of HIV treatment, such as fear of becoming infected (p $<$.001 and p =.012, respectively). Residency trained physicians also expressed a greater comfort with discussing sexually-related topics with their patients than did non-residency trained physicians (p $<$.001). There were 67.1% of the physicians surveyed who reported never providing treatment to an individual with HIV disease. Residency trained and board certified physicians expressed a greater likelihood to provide treatment to HIV-infected patients (p $<$.001) than non-residency trained and non-board certified physicians.^ Among the various primary care specialties, family medicine is especially vulnerable to the current challenges of HIV/AIDS. These challenges are augmented by the epidemiologic pattern that characterizes AIDS. For the past several years, we have seen AIDS in this country assume a similar pattern to that seen in most other countries; HIV is becoming increasingly prevalent in the heterosexual population as well as in locations removed from metropolitan centers. This current phase of the epidemic generates greater pressures upon primary care physicians, particularly family physicians, to become better acquainted with the means to provide early care to HIV/AIDS patients and to prevent HIV/AIDS among their patients. Family medicine is especially appropriate for providing care to HIV patients because family medicine involves treatment to all age groups and conditions; other primary care specialties focus on limited patient populations or specific conditions. Family physicians should be armed with the expertise to confront HIV/AIDS. However, family physicians' clinical competence and experience with HIV is not known. The data collected in this survey describes their competencies, attitudes, and experiences. ^
Perinatal mortality and quality of care at the National Institute of Perinatology: A 3-year analysis
Resumo:
Quality of medical care has been indirectly assessed through the collection of negative outcomes. A preventable death is one that could have been avoided if optimum care had been offered. The general objective of the present project was to analyze the perinatal mortality at the National Institute of Perinatology (located in Mexico City) by social, biological and some available components of quality of care such as avoidability, provider responsibility, and structure and process deficiencies in the delivery of medical care. A Perinatal Mortality Committee data base was utilized. The study population consisted of all singleton perinatal deaths occurring between January 1, 1988 and June 30, 1991 (n = 522). A proportionate study was designed.^ The population studied mostly corresponded to married young adult mothers, who were residents of urban areas, with an educational level of junior high school or more, two to three pregnancies, and intermediate prenatal care. The mean gestational age at birth was 33.4 $\pm$ 3.9 completed weeks and the mean birthweight at birth was 1,791.9 $\pm$ 853.1 grams.^ Thirty-five percent of perinatal deaths were categorized as avoidable. Postnatal infection and premature rupture of membranes were the most frequent primary causes of avoidable perinatal death. The avoidable perinatal mortality rate was 8.7 per 1000 and significantly declined during the study period (p $<$.05). Preventable perinatal mortality aggregated data suggested that at least part of the mortality decline for amenable conditions was due to better medical care.^ Structure deficiencies were present in 35% of avoidable deaths and process deficiencies were present in 79%. Structure deficiencies remained constant over time. Process deficiencies consisted of diagnosis failures (45.8%) and treatment failures (87.3%), they also remained constant through the years. Party responsibility was as follows: Obstetric (35.4%), pediatric (41.4%), institutional (26.5%), and patient (6.6%). Obstetric responsibility significantly increased during the study period (p $<$.05). Pediatric responsibility declined only for newborns less than 1500 g (p $<$.05). Institutional responsibility remained constant.^ Process deficiencies increased the risk for an avoidable death eightfold (confidence interval 1.7-41.4, p $<$.01) and provider responsibility ninety-fivefold (confidence interval 14.8-612.1, p $<$.001), after adjustment for several confounding variables. Perinatal mortality due to prematurity, barotrauma and nosocomial infection, was highly preventable, but not that due to transpartum asphyxia. Once specific deficiencies in the quality of care have been identified, quality assurance actions should begin. ^

A methodology is described for understanding the interaction of karstic aquifers with allogenic rivers, where little information is available. This methodology includes conventional hydrogen- ology methods tracer tests and measurements of flow into, out of and circulating within the karstic system. The method is designed to un- derstand the hydrogeological behaviour of a river in sufficient detail, given a short study pe- riod. The methodology is applied to a karstic system in Spain, obtaining useful, quantitative results for a hydrological year, such as an esti- mate of the water balance, differentiation be- tween autogenic and allogenic natural recharge, relationship and connection between the river and the aquifer, and measurements of infiltration capacity in watercourses under different hydro- logical situations. The paper deals with a useful example that could be applied to other rivers and aquifers where few data are available. It can be applied to aquifers under a natural regime and Mediterranean climate.
