Cognitive processing therapy for veterans with military-related posttraumatic stress disorder.

Abstract: Sixty veterans (54 men, 6 women) with chronic military-related posttraumatic stress disorder (PTSD) participated in a wait-list controlled trial of cognitive processing therapy (CPT). The overall dropout rate was 16.6% (20% from CPT, 13% from waiting list). Random regression analyses of the intention-to-treat sample revealed significant improvements in PTSD and comorbid symptoms in the CPT condition compared with the wait-list condition. Forty percent of the intention-to-treat sample receiving CPT did not meet criteria for a PTSD diagnosis, and 50% had a reliable change in their PTSD symptoms at posttreatment assessment. There was no relationship between PTSD disability status and outcomes. This trial provides some of the most encouraging results of PTSD treatment for veterans with chronic PTSD and supports increased use of cognitive- behavioral treatments in this population.

Plasmid-Determined AmpC-Type β-Lactamases

Abstract: The predominant mechanism for resistance to β-lactam antibiotics in gram-negative bacteria is the synthesis of β-lactamase. To meet this challenge, β-lactams with greater β-lactamase stability, including cephalosporins, carbapenems, and monobactams, were introduced in the 1980s. Resistance

Evidence of increased oxidative damage in both sporadic and familial amyotrophic lateral sclerosis.

Abstract: Some cases of autosomal dominant familial amyotrophic lateral sclerosis (FALS) are associated with mutations in the gene encoding Cu/Zn superoxide dismutase (SOD1), suggesting that oxidative damage may play a role in ALS pathogenesis. To further investigate the biochemical features of FALS and sporadic ALS (SALS), we examined markers of oxidative damage to protein, lipids, and DNA in motor cortex (Brodmann area 4), parietal cortex (Brodmann area 40), and cerebellum from control subjects, FALS patients with and without known SOD mutations, SALS patients, and disease controls (Pick's disease, progressive supranuclear palsy, diffuse Lewy body disease). Protein carbonyl and nuclear DNA 8-hydroxy-2'-deoxyguanosine (OH8dG) levels were increased in SALS motor cortex but not in FALS patients. Malondialdehyde levels showed no significant changes. Immunohistochemical studies showed increased neuronal staining for hemeoxygenase-1, malondialdehyde-modified protein, and OH8dG in both SALS and FALS spinal cord. These studies therefore provide further evidence that oxidative damage may play a role in the pathogenesis of neuronal degeneration in both SALS and FALS.

Low level of response to alcohol as a predictor of future alcoholism.

Abstract: Objective As part of a search for measurable attributes of an individual that might be related to the risk of alcoholism, the author's group previously compared 227 sons of alcoholics and 227 matched comparison subjects at the age of about 20 years. Forty percent of the men at high risk for alcoholism and less than 10% of the comparison subjects demonstrated a low intensity of response to alcohol challenge. This article reports the results of the follow-up of the first half of this study group almost a decade later. Method Of the men who had been tested at about age 20, 223 were about age 30 at this evaluation, which included personal and resource-person interviews, record searches, urine toxicology screens, and blood level markers of drinking. Results A low level of response to alcohol at age 20 was associated with a fourfold greater likelihood of future alcoholism in both the sons of alcoholics and the comparison subjects. Fifty-six percent of the sons of alcoholics with the lesser alcohol response developed alcoholism during the subsequent decade, compared to 14% of the men in this group who had highly sensitive alcohol responses. Neither family history of alcoholism nor response to alcohol predicted any other psychiatric diagnoses over the subsequent decade, and neither was a significant predictor of any other substance use disorder. Conclusions In a heavy-drinking society, a lower sensitivity to modest doses of alcohol is associated with a significant increase in the risk of future alcoholism, perhaps through increasing the chances that a person will drink more heavily and more often.
