Safety Behaviors of Abused Women After an Intervention During Pregnancy

Objective: To evaluate an intervention protocol, administered during pregnancy, for increasing safety-seeking behaviors of abused women.
Design: Prospective, ethnically stratified cohort analysis.
Setting: Public prenatal clinics.
Participants: Pregnant women reporting physical or sexual abuse in the year before or during the present pregnancy. One hundred thirty-two women met study criteria, received the intervention, and were followed for 1 year after the completion of the pregnancy.
Intervention: Three education, advocacy, and community referral sessions that included information on safety behaviors.
Main outcome Measure: Adoption of safety behaviors by abused women. Safety behaviors were measured before the intervention, twice during pregnancy, and at 2, 6, and 12 months after completion of the pregnancy.
Results: Repeated measures analysis of variance showed a significant increase in adoption of each safety behavior (p < .0001), with most behaviors showing a significant increase after the first intervention session.
Conclusions: Pregnant women who were abused and were offered an intervention protocol report a significant increase in safety behavior adoption during and after pregnancy. Abuse during pregnancy is common. Identification of abuse and immediate clinical intervention that includes information about safety behaviors can result in safety behavior adoption that may prevent future abuse and increase the safety and well-being of women and infants.     

Children of migratory agricultural workers: the ecological context of acute care for a mobile population of immigrant children

Migratory and seasonal agricultural workers fill the labor needs of United States farmers. Although migrant workers are a culturally and ethnically diverse population, presently, they are predominantly immigrants of Hispanic ethnicity. Migrant farm workers are increasingly young, financially impoverished, male, undocumented immigrants from Mexico. Families with children constitute 45% of this population. The ecological context of migrant children’s lives is characterized by poverty, social isolation, heightened inter- and intra-national mobility, limited protections from occupational safety and health legislation, and health access barriers. Moreover, the linkage of citizenship and immigration status to the receipt of public insurance and selected social services benefits has the potential to increase access barriers for migrant workers and their families. Despite these obvious vulnerabilities, few health services research studies address this population. Most of what is known relates to adults, with very little known about migrant children’s health services utilization patterns or health morbidities. In the emergency department setting, the differential approach required to care for children, as compared to adults, must be modified further in order to address the unique needs of this vulnerable population. The effective delivery of acute care to the children of migratory agricultural workers requires awareness of and attention to their unique health access barriers, issues of continuity and compliance with care, and their unique health and injury risks.     

Osteonecrosis of the jaws by long term therapy with bisphosphonates]

For several decades bisphosphonates have been used to reduce skeletal related events in patients with both osteoporosis or bone metastases. Under long term application, besides the known therapy side effects, a new clinical picture has been described within the last few years. This is osteonecrosis of the jaws, which is characterized by its difficulty in treatment. Besides exposed jaw bone, the start of the disease usually lacks any symptoms. The typical clinical symptoms then are foetor ex ore, swelling, exsudation, loosening of teeth, pain or paresthesia. Later oro-antral/nasal or oro-cutaneous fistula can develop. The X-ray shows persisting tooth sockets after extractions and later cloudy radio-lucency, sequestra or fractures. The patient exposed to bisphosphonate can be grouped according to the risk for osteonecrosis: high risk patients with intravenous bisphosphonate therapy and additional chemo-, radiation or corticoid therapy--predominantly patients with a malignant underlying disease and bone metastases low risk patients with an oral bisphosphonate therapy without additional chemo-, radiation or corticoid therapy--preferably patients with non-corticoid-induced osteoporosis. Before starting a bisphosphonate therapy possible causes of infection should be treated and risk of injuries to the mucosa should be reduced according to the individual risk profile. This is supplemented by information of the patient about the risk of necrosis and the possibilities for prevention. Regular dental recall under bisphophonate therapy is emphasised for early recognition of possible problems. Prophylaxis is recommended for the prevention of periodontal infection combined with a follow up of removable denture for possible ulcera. Generally, conservative treatment measures are preferred to surgical ones. Inevitable operations are carried out non-traumatically using broad spectrum antibiotic prophylaxis until the day of suture removal (not before day 10). Long term follow up examinations are recommended.Patients with dental implants inserted before a bisphophonate therapy should be subject to intensive recall examinations. For patients undergoing or following a bisphosphonate therapy the indication for dental implants should be as strict as for patients following head and neck radiation therapy. In the present for patients with osteonecrosis, even after healing, dental implants are regarded as contra-indication. Therapy of the necrosis often requires general anaesthesia, hospitalisation, naso-gastral feeding tube and intravenous, systemic antiinfective treatment. The necrosis is removed completely and a tension free wound closure with vascularised tissue is intended. A literature review shows the metabolic effect of biphosphonates, the known pathogenesis of the bisphosphonate-induced jaw necrosis. It is essential to develop interdisciplinary communication, aiming at a joint care for this group of concerned patients and involving not only those medical disciplines, which order and use bisphosphonates, but especially dentists and maxillofacial surgeons.     

Dose delivery characteristics of the AIR pulmonary delivery system over a range of inspiratory flow rates.

The purpose of this study was to evaluate the in vitro and in vivo dose delivery characteristics of the AIR pulmonary delivery system over a range of flow rates. A 5-mg placebo powder of engineered particles with low densities (<0.4 g/cc) and large geometric diameters (>5 microm) was delivered via a simple, capsule based, passive dry powder inhaler. The emitted dose, geometric and aerodynamic particle size distributions (aPSDs) were obtained over a range of flow rates (15-60 LPM). The in vitro results demonstrated improved powder dispersion with increasing flow rate through the inhaler. The in vivo dose delivery characteristics were obtained by gamma scintigraphy. Twelve healthy subjects performed the following three inhalation maneuvers: (i) a targeted peak inspiratory flow rate (PIFR) of 20 +/- 10 LPM, (ii) a deep comfortable inhalation, and (iii) a deep forced inhalation. PIFR and inhaled volume were obtained during the inhalation of the dose using a spirometer. In vivo dose delivery was characterized by high and reproducible emitted doses (mean = 87%; inter and intra-subject CV = 5%) and high lung deposition (mean = 51% of the total dose), with low inter and intra-subject CVs (18% and 13%, respectively) across a range of PIFRs (12-86 LPM). Lung deposition of the total dose was shown not to be dependent on PIFR by analysis of variance across the range of inspiratory flow rates (p = 0.29). This was due to the competing effects of smaller aPSDs, increased extrathoracic deposition and higher emitted doses with increasing PIFR. Fully characterizing the effect of inspiratory flow rate requires analysis of the therapeutic response, as well as in vitro dose delivery and lung deposition.     

Osteosarcoma relapse after combined modality therapy: an analysis of unselected patients in the Cooperative Osteosarcoma Study Group (COSS).

PURPOSE: To evaluate the impact of patient, tumor, and treatment-related factors on outcome in unselected patients with recurrent osteosarcoma. PATIENTS AND METHODS: Five hundred seventy-six consecutive patients who had achieved a first complete surgical remission (CR) during combined-modality therapy on neoadjuvant Cooperative Osteosarcoma Study Group (COSS) protocols and then developed recurrent osteosarcoma were analyzed (median time from biopsy to relapse, 1.6 years; range, 0.1 to 14.3 years). There were 501 patients with metastases, 44 with local recurrences, and 31 with both. Metastases involved lungs (469 patients), bones (90 patients), and/or other sites (54 patients). RESULTS: After a median follow-up of 1.2 years for all patients and 4.2 years for survivors, actuarial overall survival (OS) rates at 2, 5, and 10 years were 0.38, 0.23, and 0.18, respectively. Five-year OS was 0.39 for 339 patients with and 0.00 for 229 patients without a second surgical CR (P < .0001). A long time to relapse, a solitary lesion, and, in the case of pulmonary metastases, unilateral disease and the absence of pleural disruption, were of positive prognostic value in uni- and multivariate analyses, as were a second surgical CR and the use of second-line chemotherapy. Radiotherapy was associated with moderately prolonged survival in patients without a second CR. The very limited prognostic differences associated with the use of second-line chemotherapy appeared to be more pronounced with polychemotherapy. CONCLUSION: Time to relapse and tumor burden correlate with postrelapse outcome in osteosarcoma. Complete surgery is an essential component of curative second-line therapy. Chemotherapy, particularly chemotherapy with more than one agent, may contribute to limited improvements in outcome.     

Diagnosis and Prevention of Hypersensitivity Reactions to Iodinated Contrast Media

Iodinated contrast media (ICM) have become one of the major causes of drug hypersensitivity reactions (HSRs) related to increasing numbers of ICM-based radiological imaging procedures. Strategies for diagnosing and preventing ICM-induced HSRs have not been uniformly standardized yet. However, advances have been made based on the results of recent research. A previous history of hypersensitivity to ICM is the most significant risk factor for developing HSR by ICM. Avoidance of culprit agents and premedication is the main strategy to prevent recurrences of HSRs in high-risk patients. In addition, we strongly recommend identifying sensitized ICM using skin tests to determine immunoglobulin E-mediated or delayed-type allergy and to guide the choice of an alternative contrast agent. ICM provocation test procedures have been established and are helpful in selected cases. In this paper, we review how to evaluate patients who have experienced immediate or delayed HSRs caused by ICM to minimize the risk of recurrence and discuss unmet needs that require further research.     

The changing of the guards : Can family doctors contain worker absenteeism?

Using administrative data from Norway, we examine the extent to which family doctors influence their clients’ propensity to claim sick-pay. The analysis exploits exogenous switches of family doctors occurring when physicians quit, retire, or for other reasons sell their patient lists. We find that family doctors have significant influence on their clients’ absence behavior, particularly on absence duration. Their influence is stronger in geographical areas with weaker competition between physicians. We conclude that it is possible for family doctors to contain sick-pay expenditures to some extent, and that there is a considerable variation in the way they perform this task.     

De Madres a Madres: Women building community coalitions for health

How one group of Hispanic women in Houston, Texas, built community coalitions for primary health care is chronicled from the perspectives of the women. We describe how they formed partnerships with community businesses, health and social service agencies, schools, and churches to develop an outreach network that enables pregnant women to obtain early prenatal care. These women's steps in coalition building are related to feminist theory, with an emphasis on group decision making, shared power for the empowerment of all, and the creation of an environment in which individual worth and dignity are enhanced and risk taking is encouraged and supported.
