Internationalization of Medical Education - Motivations and Formats of Current Practices.

Purpose: The COVID-19 pandemic has demonstrated the importance for medical professionals to engage in work transcending national borders and to deeply understand perspectives of health in other countries. Internationalization of medical education can play a key role to that end, by preparing culturally competent and globally conscious medical healthcare professionals.The aim of this scoping review is to identify current practices and formats in internationalization in medical education, which to date has received sparse academic attention.

Subjective Responses to Alcohol in the Development and Maintenance of Alcohol Use Disorder.

Objective: Alcohol use disorder (AUD) remains an urgent public health problem. Longitudinal data are needed to clarify the role of acute subjective responses to alcohol in the development and maintenance of excessive drinking and AUD. The authors report on 10 years of repeated examination of acute alcohol responses in the Chicago Social Drinking Project.

The role of alcohol response phenotypes in the risk for alcohol use disorder.

Heavy alcohol use is pervasive and one of our most significant global health burdens. Early theories posited that certain alcohol response phenotypes, notably low sensitivity to alcohol ('low-level response') imparts risk for alcohol use disorder (AUD). However, other theories, and newer measures of subjective alcohol responses, have challenged that contention and argued that high sensitivity to some alcohol effects are equally important for AUD risk.

Effects of naltrexone on smoking cessation outcomes and weight gain in nicotine-dependent men and women.

This study examined whether the opioid receptor antagonist naltrexone is efficacious in smoking cessation and whether sex moderates the response. We assessed smoking quit rates and weight gain in a double-blind randomized trial comparing oral naltrexone (n = 162) with placebo (n = 154) in nicotine-dependent participants who wanted to quit smoking. The medication was gradually titrated up to 50 mg during the week before the quit date and then maintained at this dose for 12 weeks.

Risk taking differences on a behavioral task as a function of potential reward/loss magnitude and individual differences in impulsivity and sensation seeking.

Although previous studies have shown that the Balloon Analogue Risk Task (BART; [Lejuez, C.W., Read, J.

Delta9-tetrahydrocannabivarin as a marker for the ingestion of marijuana versus Marinol: results of a clinical study.

Delta9-tetrahydrocannabinol (THC), the main psychologically active ingredient of the cannabis plant (marijuana), has been prepared synthetically and used as the bulk active ingredient of Marinol, which was approved by the FDA for the control of nausea and vomiting in cancer patients receiving chemotherapy and as an appetite stimulant for AIDS patients. Because the natural and the synthetic THC are identical in all respects, it is impossible to determine the source of the urinary metabolite of THC, 11-nor-delta9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH), in a urine specimen provided in a drug-testing program. Over the last few years there has been a need to determine whether a marijuana positive drug test is the result of the ingestion of marijuana (or a related product) or whether it results from the sole use of Marinol.

Reinforcing and subjective effects of diazepam in nondrug-abusing volunteers.

Preference for diazepam was assessed in 18 light and 12 moderate social drinkers using a cumulative dosing procedure. The 7-session procedure consisted of: 1) four sampling sessions, during which participants ingested color-coded capsules containing either diazepam (five 4-mg capsules administered at 30-min intervals; total dose 20 mg) or placebo, and 2) three choice sessions, during which they could ingest up to 7 capsules of their preferred color of capsule, each separated by 30 min. Subjective (mood) and behavioral (performance) measures were obtained throughout the 4-hour sessions.

Assessing individual differences in ethanol preference using a cumulative dosing procedure.

Preference for ethanol versus a placebo was assessed in 12 normal volunteers usina a cumulative dosing preference test. The test consisted of four sampling sessions followed by three choice sessions. During the sampling sessions subjects received either five cumulating oral doses of ethanol (0.

Risks and benefits of long-term benzodiazepine use.

Despite a sharp decline in the prescription of benzodiazepines during the past decade, reservations about their use have continued to escalate. This article presents converging data from three diverse sources: national survey data from consumers, laboratory data on the drug preferences of normal subjects, and a controlled clinical study of long-term diazepam treatment and withdrawal. These data suggest that (1) the risks of overuse, dependence, and addiction with benzodiazepines are low in relation to the massive exposure in our society; (2) benzodiazepine addiction can occur when doses within the clinical range are taken regularly over about 6 months; (3) many patients continue to derive benefit from long-term treatment with benzodiazepines; and (4) attitudes strongly against the use of these drugs may be depriving many anxious patients of appropriate treatment.

Behavioral and pharmacological treatment of cigarette smoking: end of treatment comparisons.

Success in a stop-smoking treatment program was compared in patients who received behavioral treatment alone (BT) or behavioral treatment plus Nicorette gum (NT). The proportion of nonsmokers at the end of the 10-week program was higher with the groups receiving BT (82%) than in those receiving NT (50%). While the groups differed in their initial tolerance levels and number of previous quit attempts, the data suggest that the addition of Nicorette gum did not confer a substantial advantage over BT alone.

Neuroleptic-induced "anhedonia" in rats: pimozide blocks reward quality of food.

The dopamine receptor blocker pimozide attenuated lever-pressing and running for food reward in hungry rats. In each case the characteristic behavior of pimozide-treated rats was the same as that of undrugged rats when reward was simply withheld. Drug-induced performance difficulties were ruled out by the presence of periods of normal responding in drug-treated animals.

Both positive reinforcement and conditioned aversion from amphetamine and from apomorphine in rats.

Rats learned to press a lever for intravenous injections of amphetamine or apomorphine. They also learned to avoid the taste of saccharin which was associated with experimenter-administered amphetamine or with self-administered apomorphine. Thus these, and presumably other, self-administered drugs serve as compound pharmacological stimuli, having both positively reinforcing and aversive properties.
