Encoded Exposure and Social Norms in Entertainment-Education

Entertainment-education is an effective health communication strategy that combines or embeds educational messages into entertainment programs to bring about social and behavior change. For years, scholars have considered how entertainment-education works. Some contemporary theories posit that entertainment-education does not engender behavior change directly but does so through mediating variables. This study adds to the literature on this topic by exploring the direct relationship between exposure and social norms instead of their relationship through behavior as a mediator. Novel to this study is the use of encoded exposure, a continuous and recognition-based measure of exposure that includes ever watching, recall, involvement, and dose in its operationalization. Using cross-sectional data from Kyunki … Jeena Issi Ka Naam Hai, an entertainment-education program in India, this exploratory analysis indicates a positive and significant relationship between encoded exposure and social norms. How can this finding be applied to future programs? Questions remain, and replication is needed, but if it is not essential to go through behavior in order to change social norms, then implications emerge for the theory and practice of entertainment-education.     

The upper GI safety and tolerability of oral alendronate at a dose of 70 milligrams once weekly: a placebo-controlled endoscopy study

OBJECTIVE: Alendronate (10 mg daily) has been shown in long term clinical trials to be an effective treatment for postmenopausal osteoporosis. A weekly dosing regimen of alendronate is preferred by both patients and physicians, as it has the potential to provide greater convenience and enhance compliance. In a 1-yr clinical trial, alendronate (70 mg once weekly) was equally efficacious and at least as well tolerated as the 10-mg daily dose in the treatment of postmenopausal osteoporosis, despite the higher unit dosage required. We conducted a randomized, double blind, placebo- and active-controlled endoscopy study to confirm the results of this clinical trial. We hypothesized that mean endoscopic gastric erosion scores would be similar in subjects receiving alendronate (70 mg once weekly) and those receiving a placebo. METHODS: Two hundred seventy-seven subjects (90 men and 187 women) were randomized to one of three treatment groups: 1) alendronate (70 mg once weekly) for 10 wk (N = 126), 2) placebo (once weekly) for 10 wk (N = 126), or 3) placebo (once weekly) for 10 wk followed by aspirin (650 mg q.i.d.) for the last week as the positive control (N = 25). Esophagogastroduodenoscopy was performed 5 to 7 days after the last dose of alendronate or matching placebo. RESULTS: The mean gastric erosion scores (Lanza scale) were similar in subjects given alendronate (70 mg once weekly) and those given a placebo (0.32 vs 0.35, respectively; 95% CI for difference = -0.22-0.16, p = 0.75), whereas scores in both groups were significantly lower than in those given aspirin (3.09; p < 0.001). Endoscopic gastroduodenal ulcers occurred in no alendronate (0%), two placebo (1.7%), and five aspirin (23.8%) subjects. The mean erosion scores in the esophagus and duodenum of alendronate and placebo subjects were also similar. The incidences of upper GI symptoms were similar in the alendronate and placebo subjects and did not suggest a relationship with endoscopic lesions. CONCLUSIONS: Alendronate (70 mg once weekly) was not associated with any increase in endoscopic lesions in the upper GI tract relative to a placebo.     

How Do Physicians and Midwives Manage the Third Stage of Labor?

ABSTRACT: Background: Current practice guidelines recommend active management of the third stage of labor. We compared practices of three maternity care provider disciplines in management of third‐stage labor and the justifications for their approach. Methods: This study is a cross‐sectional survey of maternity practitioners in usual practice settings in British Columbia. All 199 obstetricians, all 82 midwives, and a random sample of family physicians practicing intrapartum maternity care (one‐third, or 346) were surveyed The three main outcome measures by discipline were the method preferred in managing third‐stage labor, the reasons given for the chosen method, and views on the appropriateness of the current third‐stage labor guideline. Results: The overall response rate was 57.8 percent. Response rates indicating that the participants were “aware of guideline” were the following: obstetricians, 85.3 percent; family physicians, 53.7 percent; and midwives, 97.8 percent. Response rates indicating that the participants “agreed with guideline” were the following: obstetricians, 95.2 percent; family physicians, 97.6 percent; and midwives, 51.2 percent. Response rates indicating that “oxytocin should be given with anterior shoulder” were the following: obstetricians, 71.1 percent; family physicians, 68.3 percent; and midwives, 26.7 percent. Response rates indicating that “routine active management of third stage of labor should be the norm” were the following: obstetricians, 79.2 percent; family physicians, 60.2 percent; and midwives, 17 percent. All results were statistically significant (p < 0.01). Conclusions: A major difference was found between physicians and midwives in the management of third‐stage labor. Physicians routinely implemented active management of the third stage of labor; midwives preferred expectant approaches, principally based on women’s preference. Provincial data did not show differences in postpartum hemorrhage or transfusion rates by practitioner type. (BIRTH 35:3 September 2008)     

Rapidly progressive glomerulonephritis in a patient with syphilis. Identification of antitreponemal antibody and treponemal antigen in renal tissue

A 37-year-old man presented with biopsy-proved rapidly progressive glomerulonephritis and a strongly positive fluorescent treponemal antibody result. The patient was treated with hemodialysis, plasmapheresis, methylprednisolone, and penicillin, with rapid improvement and stabilization of renal function. Antibody was eluted from the frozen renal tissue and demonstrated a strongly positive reaction to the treponemal antigen when used in the fluorescent treponemal antibody test. In addition, when specific rabbit antitreponemal antiserum was applied to the frozen renal sections, there was a strongly positive reaction. Although syphilis has been associated with membranous glomerulopathy and post-infectious glomerulonephritis, this appears to be the first case of latent syphilis in which rapidly progressive glomerulonephritis has been identified. The presence within the glomeruli of treponemal antigen and antitreponemal antibody supports the association of these two entities.     

A possible explanation for the gastrointestinal mucosal lesion in immunoglobulin deficiency state

A patient with immunoglobulin deficiency is reported in whom intestinal biopsies over a 6-year period showed progression from a nearly normal mucosal villous structure to a flat mucosal lesion, a finding not previously reported. Detailed light and electron microscopic studies of the patient's gastrointestinal mucosal biopsies failed to show evidence that the lesion was related to bacterial or parasitic invasion. However, morphologic evidence was obtained suggesting that the intestinal lesion was related to a viral enteritis. It is postulated that the intestinal cells were infected by a myxovirus, and that this resulted in damage of some intestinal mucosal cells and in slowed growth of others—a reverse cancer effect. The data are not conclusive, and other mechanisms for the lesion must remain under consideration.Supported in part by Grant AM 13725 from NIAMD, USPHS and by Part I Funds from the Veterans Administration.
