Can an Internet-based system assist with administration and distance learning for third- and fourth-year rural clinical rotations?

This article describes the experience of the West Virginia School of Osteopathic Medicine during the past 5 years in using Internet technology to communicate with osteopathic medical students on remote, community-based clinical rotations. Federal funding initially supported creation of a new Internet-based system to connect students on their rural family medicine rotations. Accomplishments during and after federal funding include development of systems for remote submission and student access to feedback about clinical sites; on-line access to rotation objectives, policies, housing information, maps, and affiliated internship opportunities; access to medical journals and texts; secured access to rotation grades and rotation schedules; on-line reading lists for family medicine and pediatrics rotations; and Internet-based test administration. Remaining challenges include identification or development of interactive learning materials; development of test banks; flawless administration of Web-based examinations; and finding the right balance between patient care-based learning and didactics.

Relationship between climate and psychiatric inpatient length of stay in Veterans Health Administration hospitals.

OBJECTIVE: The study examined whether climate has an impact on inpatient psychiatric length of stay in Veterans Health Administration hospitals (VHA). METHOD: Data from the National Weather Service for eight climate variables for the locations of 134 VHA hospitals nationwide were factor analyzed, resulting in two climate factors representing temperature and precipitation. Factor scores were correlated with psychiatric mean lengths of stay from 1994 to 1998 for 99 VHA hospitals with inpatient psychiatric services and for the 22 VHA regional divisions (Veterans Integrated Service Networks). RESULTS: Climate factors correlated modestly but significantly with length of stay, with correlations ranging from -0. 25 to -0.37 at the hospital level and from -0.38 to -0.45 at the VHA regional level; hospitals in warmer and drier climates had shorter lengths of stay. Medical centers in colder climates had the longest lengths of stay in winter and fall. The significant correlation between climate and length of stay was not affected by recent reductions in length of stay in VHA hospitals. CONCLUSIONS: Higher clinical costs associated with longer lengths of stay in colder climates have implications for budget planning. Climate factors must also be recognized for their potential effect on performance monitoring systems focused on hospital utilization. Researchers must continue to consider broader contextual variables such as climate if they are to fully understand the determinants of health care utilization and psychiatric hospitalization costs.

Mammalian chitinase-like proteins.

Mammals express genes coding for proteins that show significant similarity to chitinases of family 18 glycosyl hydrolases. These chitinase-like proteins have no chitinase activity due to changes in critical residues in the putative active center. One of these is oviductin, a high molecular weight glycoprotein most likely involved in fertilization and protection of the tubal epithelium owing to its mucin character. Another is YKL-40 (HCgp39) produced in association with tissue remodeling. Such proteins could have a general function in morphogenesis.

Monoamine roles in retention and reversal of delayed response in cats.

Two experiments were performed to study the effects of manipulation of central monoamines upon behavior in a delayed response (DR) situation. In the first study, serotonin (5-HT) levels were increased by administration of 5-hydroxy-L-tryptophan (5-HTP) and RO4-4602, a decarboxylase inhibitor, to cats that had overlearned the DR. This intervention had no significant effect upon performance in the 0 sec delay condition, but significantly increase error and non-response scores during delay trials; the effect is specific to an "information holding" demand upon the animal and according to the neurochemical analysis appears to be due to a central effect of 5-HT. In a second experiment, dopamine levels were raised by L-DOPA administration during a reversal of the original DR situation, and the effect of L-DOPA on the evolution of response strategies was observed. All animals developed a position habit that proved impossible to correct but L-DOPA animals developed a significant position habit more quickly than controls, thus suggesting a possible relationship between the neostriatal dopamine accumulation and behavioral plasticity.

Effect of metergoline on delayed response in cats and its relation to the metabolism of dopamine and serotonin in neostriatal and mesolimbic neurons.

In cats the effect of Metergoline (Liserdol, Farmitalia) was investigated on the performance of a delayed response task and was related to the associated changes in the concentrations of dopamine, nonadrenaline and serotonin in the brain. Metergoline (14 microgram/kg/day, i.m.) administered during the first 10 days of the training significantly decreased response latencies at delay periods of 0, 3, 9 and 27 sec without significantly affecting the number of errors. Biochemical assays showed that the improved performance correlated with the increased dopamine content of limbic structures and the decreased serotonin content in all brain structures. The concentrations of dopamine in the neostriatum remain unchanged. Response latencies and the number of errors in cats treated with Metergoline were significantly different from those in animals treated with L-DOPA (30 mg/kg/day) probably relfecting the specific biochemical disturbance induced by the two drugs. These results suggest an inhibitory influence of serotoninergic pathways on areas like the meso-limbic system retaining high concentrations of dopamine.

Convalescence following coronary surgery: a group experience.

The patient who has heart surgery and returns home will experience many problems in adjusting to a modified lifestyle. Successful rehabilitation depends on many factors-the knowledge the patient has about his condition, his own motivation and the support he receives from family and friends. If he has received good teaching in the hospital, his task will be much easier. But is in-hospital teaching enough? Current nursing research suggests that patients are more receptive to health teaching after they have returned home and benefit from sharing experiences with a group. The author describes the results of an investigation into the concerns of convalescent coronary patients and their wives and tells how group sessions helped ease their transition from hospital to a productive lifestyle.
