September 11th related stress and trauma in New Yorkers

Exposure to trauma and stress has been linked with poor health, while forgiveness appears to be positively associated with health outcomes. The current study investigates whether traits such as forgiveness and ruminative tendencies predict levels of trauma and stress experienced by New York City residents on the 1‐year anniversary of the September 11th terrorist attack. Seventy‐one students and staff members (57 females, 14 males) of a graduate school in New York City were administered the Impact of Events Scale, the Perceived Stress Scale, and questionnaires designed for the purpose of this study to measure ruminative tendencies and forgiveness on September 11, 2002. Rumination predicted levels of trauma (p < 0.05) and perceived stress (p < 0.01). Lower levels of forgiveness predicted perceived stress (p < 0.05), but not trauma. Rumination mediated the relationship between forgiveness and perceived stress. These findings suggest that individuals with higher levels of rumination have an elevated risk of experiencing trauma and stress‐related symptoms following a traumatic event. Forgiveness is associated with lower levels of stress, but not trauma, perhaps because trauma is an extreme form of stress. Forgiveness appears to serve as a buffer against stress more so in individuals with low levels of rumination than in individuals with high levels of rumination.

Caries experience and fluorosis prevalence in Chilean children from different socio-economic status

Abstract Caries experience and enamel fluorosis prevalence in 8-year-old children belonging to different socio-economic classes were determined in two Chilean twin cities that are served by optimally fluoridated community water from the same waterworks facility. Low socio-economic status (LSES) children had a higher mean dm ft and DMFT indices (P<0.001) than high socioeconomic status (HSES) children. Prevalence of enamel fluorosis in the permanent teeth of LSES children was 0.79, significantly higher (X²= 9.0; P<0.003) than the value 0.59 found in HSES children. The proportion of Dean's scores 2. 3, 4 and 5 in first molars, mandibular and maxillary incisors in LSES children was higher than in HSES children (P<0.001). Differences in prevalence and seventy of enamel fluorosis between both groups are tentatively attributed lo a different pattern of tap water and tea consumption at pre-school ages. Suggestions are advanced to minimize the undesirable prevalence and severity of enamel fluorosis.     

Investigations of a novel ferrocene-containing lipid by cyclic voltammetry and cryogenic transmission electron microscopy

A novel chiral redox-active ferrocene compound (FcVI) with amphiphilic properties has been synthesized. Cryogenic Transmission Electron Microscopy (cryo-TEM) has been used to estimate the shape and size of the FcVI aggregates in solution. Uni- and multi-lamellar vesicles (between 40 and 300 nm in diameter) were observed in water. Large particles (of more than 1 μm in diameter) with a hexagonal fine structure were found in 50 mM aqueous Na₂SO₄ solution. Sonication transformed the latter into ‘rosette’-like structures. Cyclic voltammetry has been employed to investigate the electrochemical properties of FcVI. The amphiphile adsorbed on graphite electrodes and a reversible electrochemical behaviour, characteristic of ferrocene, was observed with redox potentials between 330 and 350 mV.     

Reducing obesity indicators through brief physical activity counseling (pace) in italian primary care settings

Background: There is an alarming prevalence of obesity and sedentariness in Western countries. An ideal context for health promotion and preventive medicine seems to be the setting of primary care provided by the general practitioner (GP).Purpose: Therefore, this study evaluated the impact of GPs’brief physical activity counseling for overweight and obese patients.Methods: Individuals recruited during routine physician visits were randomly split into an experimental (n = 48) group that received the Patient-centered Assessment and Counseling for Exercise (PACE) protocol, and a usual-care control (n = 48) group. Body mass index (BMI) and abdominal girth were assessed as objective biometrical parameters. Patients in the experimental group self-reported their readiness for physical activity and self-efficacy.Results: The experimental group had significantly better BMI and abdominal girth compared with the control group after a 5- to 6-month follow-up. Furthermore, the experimental group progressed in their stage of physical activity readiness and increased their self-efficacy.Conclusions: The GPs’counseling for physical activity using the PACE protocol influenced mediators and biometrical outcomes in an Italian primary care context.

Provider attitudes regarding use of an immunization information system to identify children with asthma for influenza vaccination.

OBJECTIVES: Despite longstanding national guidelines, many children with asthma do not receive annual influenza vaccinations. Information from Medicaid-administrative claims data was integrated into the Michigan Care Improvement Registry (MCIR) to prompt providers regarding influenza vaccination among children with high-risk conditions such as asthma. The attitudes of pediatric primary care providers regarding the implementation of this system were assessed. METHODS: A survey was sent in February 2006 to office-based general pediatricians (n = 300) and family physicians (n = 300) in Michigan. The survey focused on influenza vaccination during the 2005-2006 influenza season and attitudes regarding a reminder system for providers using the MCIR. RESULTS: Overall response rate was 67 percent. MCIR participation was high (91%) among respondents, and most (83%) had MCIR information available to them prior to visits with pediatric patients. Most physicians (75%) considered the MCIR high-risk indicator for influenza vaccination a feature that they would find helpful. Some respondents reported concerns that the reminder system is limited to Medicaid patients only (44%) and regarding the completeness of Medicaid data to identify children with asthma (24%). CONCLUSIONS: Physicians have a positive overall view of a statewide registry-based automated reminder system to assist in identifying children with asthma for influenza vaccination, albeit with specific areas of concern.     

The diagnosis of sleep-related breathing disorders

Information regarding sleep apnea syndromes and primary alveolar hypoventilation has been widely disseminated in both medical and lay publications. As a result, the pulmonary physician is confronted with a growing number of patients referred for evaluation of sleep-related breathing disorders. In addition, many pulmonary diseases may become worse during sleep. A wide variety of diagnostic options is available. The method chosen will depend on availability, cost, and the strength of the clinical impression. Screening studies, from the most simple (night-time Holter monitor or ear oximetry) to either a carefully performed nap study or a home recording may aid in deciding which patients require a formal polysomnogram. Centers with full all-night study capability may not use preliminary recordings at all. Because many therapeutic modalities exist, their intelligent use requires an accurate assessment of the type and severity of the breathing disorder.
