Bionomics of two forensically important blowfly species Chrysomya megacephala and Chrysomya putoria (Diptera: Calliphoridae) reared on four types of diet

The use of heterogeneous animal tissues for the rearing of necrophagous insect species can produce uneven biological data, which can compromise the determination of larval age and, consequently, estimates for post-mortem intervals. We investigated the development of two species, Chrysomya megacephala and Chrysomya putoria (Diptera: Calliphoridae), reared on four substrates: minced beef (control) and semi-synthetic diets with the addition of sardine, rumen or chicken eggs. No differences in total developmental times were detected among larvae reared on different diets. Length and width of larvae were partially affected by the type of food. Third instar larvae and pupae of both species were heavier on beef treatment when compared with other substrates. Overall mortality was lower when beef was used as food. Longevity of adults and sex ratio were not negatively affected by the use of diets. Egg-based diet was the least effective for both species. Given the fact that several bionomical parameters of larvae reared on diets were close to those obtained when minced beef was offered, and considering the putrid odour, frequency of contamination and lack of homogeneity of animal tissue, semi-synthetic diets can be used for rearing C. megacephala and C. putoria.     

Mother-daughter dyads view the family: Associations between divergent perceptions and daughter well-being

Divergent perceptions (or disagreements) within the mother-daughter dyad and the association of such divergence with daughter's affective and behavioral well-being were examined in the current study. One hundred sixty-one mother-daughter dyads (daughters aged 14–18 years; mothers aged 37–59 years) completed paper- and-pencil measures assessing their perceptions of family cohesion and family conflict; daughters also rated their own depressive affect and dieting behavior. While the means for groups of mothers and daughters on family cohesion and conflict were similar, dyads varied substantially in their level of agreement. Disagreements on family cohesion were associated with daughter dieting behavior; maternal employment status was more highly associated with daughter depressive affect than either family conflict or cohesion. Findings are discussed in terms of their implications for studying the divergent perceptions of family members, and for family systems and relationship approaches to understanding the family.The research presented in this paper was supported by the W.

Binge eating in anorexia nervosa predicts later onset of substance use disorder: A ten-year prospective,longitudinal follow-up of 95 adolescents

The cooccurrence of binge eating and increased alcohol intake and substance abuse has been reported in clinical and community epidemiological samples. To further investigate the nature and causes of this comorbidity, we examined the 10-year prospective, longitudinal course of illness in 95 nonsubstance abusing adolescents hospitalized for treatment of anorexia nervosa. Survival analysis with Cox regression was used to quantitate the cumulative risk of developing substance use disorder (SUD) as a function of patterns of binge eating vs. dietary restraint within this cohort. Subjects who were binge eating at the time of intake were robustly distinguished from restrictors, having increased risk of SUD as well as greater likelihood of having at least one first-degree relative with SUD. The findings suggest binge eating that develops in the underweight stage of anorexia nervosa may reflect developmental, biological, and genetic risk processes shared in common with SUD.Received Ph.D. in clinical psychology from the University of Pittsburgh.

The analysis of biological samples from crime scene for a future human DNA profile confrontation. Effects of presumptive test reagents on the ability to obtain STR profiles for human identification

Because of the increase of evidence of blood stains, that have been washed or cleaned in an attempt to mask the analysis of DNA profiles, there is also an increase in the use of presumptive tests on samples sent to laboratories. Some of the presumptive tests, used to identify blood and semen stains, could potentially affect the recovery of high molecular weight DNA from the samples, or extinguish them, especially those already present in small quantities. After the presumptive tests, often these samples are discarded. This study aimed to examine the possibility of obtaining a DNA profile from samples submitted for presumptive testing and cleaned with bleaches with and without chlorine. Two different protocols were conducted: (a) A unique sample of human blood in natura (5 μL), already typed through the DNA techniques with the genetic profile previously known (control), was distributed onto cotton fabrics and dried at room temperature. Four samples of fabric were macerated in saline solution and Coombs serum and then stored for three months (room temperature and freezer −20 °C). (b) Another sample of human blood, type A, in natura, already typed through the techniques of DNA (control) was used. Aliquots of 200 μL were distributed in: cotton, denim and synthetic fabric. The samples were dried at room temperature for 24 h. The blood stains in those fabrics (cotton, denim and synthetic) were then divided into three groups: unwashed, cleaned with chlorine bleach and cleaned with chlorine bleach and soap powder. The samples were again dried at room temperature for 24 h, before the use of luminol. The DNA were extracted with Chelex 100 and amplified with the Identifiler Kit (Applied Biosystems). The blood stains exposed to saline and Coombs serum had DNA profiles consistent with untreated samples (controls). This result shows that the experts should keep and store the samples treated with saline and Coombs serum for future DNA confrontation when necessary. Also discussed in this paper the pattern of blood stains after washing with bleaching solutions, as well as the quantity of DNA obtained from these samples.     

Patient dumping in the hospital emergency department: renewed interest in an old problem

Alarm about the adverse effects of transferring emergency patients for economic reasons has resulted in federal legislation aimed at curbing the practice. We review the history of common law hospital liability for denial of emergency care and analyze the federal legislation designed to restrict the transfer of medically indigent patients with emergency problems. We conclude that the currently proposed solutions to patient dumping will have limited effectiveness without more specific incentives for the provision of health care to the medically indigent.
