Prevalence and trends of substance abuse in Harris County, Texas, 1989 to 1991

In the late 1980s, Harris County, Texas began experiencing an escalation of drug-related activities. Various indicators used in this analysis tracked drug-related trends from 1989 to 1991 to determine patterns for comparison of local (Houston/Harris County, Texas) to national levels.^ An important indicator of the drug scenario was drug-related activities among youths, which increased during the period of this study. The Harris County Juvenile Probation Department showed that among arrests for drug-related activities, felonies increased from 25% in 1988 to 53% in 1991. With the rise in drug-related crimes, and substance abuse among the student body, school districts were forced to institute drug education programs in an effort to curtail such activities.^ Law enforcement agencies in the county saw increased demands for their services as a result of drug activities. Harris County Sheriffs Department reported a 32% plus increase in drug-related charges between 1986 and 1991. Houston Police Department reported an increase of 109% for the same period.^ Data from the Harris County Medical Examiner, the National Institute of Justice's Drug Use Forecasting System (Houston), and drug treatment facilities around Houston/Harris County, Texas indicated similar drug usage trends. Over a four-year period (1988-91), the drugs most frequently detected during blood and urine analyses were cocaine, followed by marijuana, heroin, LSD, and methamphetamines.^ From 1988 to 1991, most drug rehabilitation organizations experienced increased demands for their services by approximately 35%. Several other organizations experienced as much as a 70 percent increase. Males accounted for roughly 70% and females about 30% of persons seeking treatment. However, the number of females pursuing treatment increased, thereby reducing the gender gap.^ Blacks in Houston/Harris County were at higher risk for drug usage among the general population, but sought treatment more readily than other ethnic groups. Whites sought treatment in similar numbers as Blacks, but overall the risk appeared smaller because they made up a larger portion of the Houston/Harris County population.^ This analysis concluded that drug trends for the Houston/Harris County, Texas did not follow national trends, but showed patterns of its own. It was recommended that other communities carry out similar studies to determine drug use trends particular to their local. ^

THE EFFECT OF FAMILY ENVIRONMENT FACTORS IN THE ETIOLOGY OF CHILD ABUSE

Twenty-three abusing couples were compared with a matched group of 23 non-abusing couples in terms of stress levels and family environment factors (cohesion, expressiveness, conflict, independence, achievement orientation, organization, control) which might mediate the response of abuse to stress. Parents who had physically abused their children were found to have significantly greater stress, conflict, and control and a significantly lower level of cohesion, independence, and achievement orientation than non-abusing parents. However, none of the mediating effects of the family environment factors reached the level of significance. ^

Beyond Bullying: Transforming the Culture of Peer Abuse

Bullying needs to be understood and positioned as a form of child abuse – peer abuse. For too many people, bullying is a benign term. This article will include information collected from a wide-range of researchers and discussions with over 50,000 students that I have facilitated during the past twenty years. The content will focus on new morbidities related to bullying such as depression and suicide, obesity, eating disorders, food allergies, juvenile diabetes, truancy, and substance and alcohol abuse. Making a cultural change in our society will require identified Change Agents, along with recommendations for collaboration, policies, projects and legislation.

Use and abuse of audivisual media in the college classroom. Slides show and web pages

The multimedia development that has taken place within the university classrooms in recent years has caused a revolution at psychological level within the collectivity of students and teachers inside and outside the classrooms. The slide show applications have become a key supporting element for university professors, who, in many cases, rely blindly in the use of them for teaching. Additionally, ill-conceived slides, poorly structured and with a vast amount of multimedia content, can be the basis of a faulty communication between teacher and student, which is overwhelmed by the appearance and presentation, neglecting their content. The same applies to web pages. This paper focuses on the study and analysis of the impact caused in the process of teaching and learning by the slide show presentations and web pages, and its positive and negative influence on the student’s learning process, paying particular attention to the consequences on the level of attention within the classroom, and on the study outside the classroom. The study is performed by means of a qualitative analysis of student surveys conducted during the last 8 school Civil Engineering School at the Polytechnic University of Madrid. It presents some of the weaknesses of multimedia material, including the difficulties for students to study them, because of the many distractions they face and the need for incentives web pages offer, or the insignificant content and shallowness of the studies due to wrongly formulated presentations.

Identification of a structural determinant for resistance to β-lactam antibiotics in Gram-positive bacteria

Streptococcus pneumoniae is the main causal agent of pathologies that are increasingly resistant to antibiotic treatment. Clinical resistance of S. pneumoniae to β-lactam antibiotics is linked to multiple mutations of high molecular mass penicillin-binding proteins (H-PBPs), essential enzymes involved in the final steps of bacterial cell wall synthesis. H-PBPs from resistant bacteria have a reduced affinity for β-lactam and a decreased hydrolytic activity on substrate analogues. In S. pneumoniae, the gene coding for one of these H-PBPs, PBP2x, is located in the cell division cluster (DCW). We present here structural evidence linking multiple β-lactam resistance to amino acid substitutions in PBP2x within a buried cavity near the catalytic site that contains a structural water molecule. Site-directed mutation of amino acids in contact with this water molecule in the “sensitive” form of PBP2x produces mutants similar, in terms of β-lactam affinity and substrate hydrolysis, to altered PBP2x produced in resistant clinical isolates. A reverse mutation in a PBP2x variant from a clinically important resistant clone increases the acylation efficiency for β-lactams and substrate analogues. Furthermore, amino acid residues in contact with the structural water molecule are conserved in the equivalent H-PBPs of pathogenic Gram-positive cocci. We suggest that, probably via a local structural modification, the partial or complete loss of this water molecule reduces the acylation efficiency of PBP2x substrates to a point at which cell wall synthesis still occurs, but the sensitivity to therapeutic concentrations of β-lactam antibiotics is lost.

Interaction of Coatomer with Aminoglycoside Antibiotics: Evidence That Coatomer Has at Least Two Dilysine Binding Sites

Coatomer is the soluble precursor of the COPI coat (coat protein I) involved in traffic among membranes of the endoplasmic reticulum and the Golgi apparatus. We report herein that neomycin precipitates coatomer from cell extracts and from purified coatomer preparations. Precipitation first increased and then decreased as the neomycin concentration increased, analogous to the precipitation of a polyvalent antigen by divalent antibodies. This suggested that neomycin cross-linked coatomer into large aggregates and implies that coatomer has two or more binding sites for neomycin. A variety of other aminoglycoside antibiotics precipitated coatomer, or if they did not precipitate, they interfered with the ability of neomycin to precipitate. Coatomer is known to interact with a motif (KKXX) containing adjacent lysine residues at the carboxyl terminus of the cytoplasmic domains of some membrane proteins resident in the endoplasmic reticulum. All of the antibiotics that interacted with coatomer contain at least two close amino groups, suggesting that the antibiotics might be interacting with the di-lysine binding site of coatomer. Consistent with this idea, di-lysine itself blocked the interaction of antibiotics with coatomer. Moreover, di-lysine and antibiotics each blocked the coating of Golgi membranes by coatomer. These data suggest that certain aminoglycoside antibiotics interact with di-lysine binding sites on coatomer and that coatomer contains at least two of these di-lysine binding sites.

Are amoxycillin and folate inhibitors as effective as other antibiotics for acute sinusitis? A meta-analysis

Objectives: To examine whether antibiotics are indicated in treating uncomplicated acute sinusitis and, if so, whether newer and more expensive antibiotics with broad spectra of antimicrobial activity are more effective than amoxycillin or folate inhibitors.

Understanding the culture of prescribing: qualitative study of general practitioners’ and patients’ perceptions of antibiotics for sore throats

Objectives: To better understand reasons for antibiotics being prescribed for sore throats despite well known evidence that they are generally of little help.

PTSD, Depression, and Substance Abuse Symptoms in Women Exposed to Intimate Partner Abuse

The present study explores relationships among several established correlates of trauma in women exposed to intimate partner abuse (IPA), including PTSD, depression, and dissociation symptoms as well as alcohol use as well as other trauma-related variables, such as social support and violence exposure. Two analysis methods were utilized: variable-oriented methods, which examine relationships between variables, and person-oriented analysis methods, which examine groupings of participants within a larger sample (N = 233). Results of the variable-oriented analyses indicated positive links among depression, PTSD, dissociation, and alcohol use in women exposed to IPA, as well as positive links between the aforementioned psychological symptoms and exposure to violence. Social support was related to decreased psychological symptoms. Person-oriented analyses indicated the presence of four unique profiles of women within the larger study sample: Profile 1 (n = 21), which was labeled High Dissociation, Low Depression/PTSD; Profile 2 (n = 150), which was labeled Low Symptoms, High Social Support, Profile 3 (n = 41); which was labeled Low Dissociation, High Depression/PTSD; and Profile 4 (n = 22), which was labeled High Symptoms, Low Social Support. This research supports previous findings about the relationships among several variables related to IPA as well as suggests the need for careful consideration of differences among women within the larger context of research, advocacy, and clinical interventions related to IPA.

Treatment Outcomes for Eating Disorder Patients With and Without Comorbid Substance Abuse Diagnoses

The impact of comorbid substance abuse and eating disorder diagnoses in an eating disorder treatment facility remains uncertain. Recent data suggest that in a substance abuse treatment setting, patients with comorbid eating disorders fared less favorably than patients without a comorbid diagnosis (Cohen et al., 2010; Glasner-Edwards et al., 2011). The purpose of this study is to compare eating disorder symptoms over the course of treatment for patients with and without comorbid substance abuse diagnoses in an eating disorder treatment facility. Archival data from an eating disorder treatment facility was used. Twenty-seven women with comorbid eating disorder and substance abuse diagnoses (EDSUD) were compared to twenty-seven women with an eating disorder diagnosis (ED) only. The subjects were compared on three scales from the Eating Disorder Inventory-III (EDI-3) by group, and pre- and post-treatment. The scales were Personal Alienation (PA), Interoceptive Deficits (ID), and Emotional Dysregulation (EmD). There was a significant decrease in symptoms post-treatment for all subjects on the PA and ID scales, and there was a significant difference between the EDSUD subjects and ED subjects on two scales. EDSUD subjects fared significantly less favorably on the ID and EmD scales. Women with EDSUD report more symptoms of Interoceptive Deficits and Emotional Dysregulation when compared to women with an ED diagnosis and no comorbid substance use. Subjects benefited from treatment in terms of less Personal Alienation and Interoceptive Deficits.

Weight-Based Emotional Abuse: Self Psychological Implications for Treatment

The aim of this paper is to provide evidence that overweight individuals are at increased risk for emotional abuse compared to their normal weight counterparts. Studies examining weight-based discrimination and bullying demonstrate examples of emotional abuse aimed at overweight individuals. The psychological difficulties associated with emotional abuse, such as symptoms of anxiety, depression and social difficulties, are reviewed. It is hypothesized that similar psychological difficulties are experienced when obese persons experience weight based emotional abuse. A self psychological conceptualization is applied to understand the effect emotional abuse has on one's sense of self. A treatment proposal, which aims to utilize self-object transferences to strengthen the self, is offered. Future research for the application of self psychology in a group therapy format is discussed.
