Tobacco smoking habits, beliefs, and attitudes among medical students in Tirana, Albania

BACKGROUND: Many surveys throughout the world have evaluated the smoking behaviors, beliefs, and attitudes of medical students, but no information is available from Albania. METHOD: A cross-sectional survey in classroom settings using a self-administered questionnaire was performed at the University of Tirana during October 2000. RESULTS: In the first and fifth years of medical school, 149 (68.5% women) and 185 (55% women) students, respectively, completed the questionnaire, with overall response rates of 82 and 92%. Tobacco smoking prevailed among males. The smoking rates among first-year medical students were 34% among men and 5% among women. Among fifth-year students, 55% of the men and 34% of the women smoked. The percentages of occasional smokers were 29 and 49%, respectively, among the first- and fifth-year students who smoked. Most medical students reported knowing the health hazards of tobacco. Most students in both groups believed that smoking should be restricted in hospitals. Slightly more than half of the students stated that they will regularly advise smokers against smoking in their future jobs. CONCLUSION: Tobacco smoking is common among medical students in Albania. Targeted antismoking training should be mandatory for medical students in Albania.     

The safety and efficacy of ciclopirox olamine for the treatment of seborrheic dermatitis

Ciclopirox olamine is a synthetic hydroxypiridone derived, broad spectrum, antifungal agent which has been used effectively to treat seborrheic dermatitis. Seborrheic dermatitis is a chronic dermatosis, more common in men than women, which usually occurs in sites dense with sebaceous glands in the form of mild inflammatory desquamate erythema. Treatment modalities for seborrheic dermatitis include keratolytic agents, corticosteroids and antifungal agents. Due to its antimycotic and anti-inflammatory activities, ciclopirox olamine is established as an effective treatment for this condition.     

A genome-wide linkage scan for dietary energy and nutrient intakes: the Health, Risk Factors, Exercise Training, and Genetics (HERITAGE) Family Study

BACKGROUND: A poor diet is a risk factor for chronic diseases such as obesity, cardiovascular disease, hypertension, and some cancers. Twin and family studies suggest that genetic factors potentially influence energy and nutrient intakes. OBJECTIVE: We sought to identify genomic regions harboring genes affecting total energy, carbohydrate, protein, and fat intakes. DESIGN: We performed a genomic scan in 347 white sibling pairs and 99 black sibling pairs. Dietary energy and nutrient intakes were assessed by using Willett's food-frequency questionnaire. Single-point and multipoint Haseman-Elston regression techniques were used to test for linkage. These subjects were part of the Health, Risk Factors, Exercise Training, and Genetics (HERITAGE) Family Study, a multicenter project undertaken by 5 laboratories. RESULTS: In the whites, the strongest evidence of linkage appeared for dietary energy and nutrient intakes on chromosomes 1p21.2 (P = 0.0002) and 20q13.13 (P = 0.00007), and that for fat intake appeared on chromosome 12q14.1 (P = 0.0013). The linkage evidence on chromosomes 1 and 20 related to total energy intake rather than to the intake of specific macronutrients. In the blacks, promising linkages for macronutrient intakes occurred on chromosomes 12q23-q24.21, 1q32.1, and 7q11.1. Several potential candidate genes are encoded in and around the linkage regions on chromosomes 1p21.2, 12q14.1, and 20q13.13. CONCLUSIONS: These are the first reported human quantitative trait loci for dietary energy and macronutrient intakes. Further study may refine these quantitative trait loci to identify potential candidate genes for energy and specific macronutrient intakes that would be amenable to more detailed molecular studies.     

California school board members' perceptions of factors influencing school nutrition policy

Enactment and enforcement of school nutrition policies represent key components in adolescent overweight and obesity prevention. This study determined: 1) California school board members' attitudes, perceptions, and motivations related to enactment of policies that support healthy eating in schools; and 2) barriers to adopting school policies that support healthy eating. To understand board members' decision-making process, key informant interviews were conducted and a survey was administered to 404 school board members. Though school board members care about the well-being of pupils, competing priorities limit the extent to which nutrition issues get addressed at board meetings. Members' decisions center primarily around academic achievement issues, yet they are interested in nutrition's overall impact on children's health and academic achievement.     

Efficacy and Speed of Onset of Pain Relief of Fast-Dissolving Paracetamol on Postsurgical Dental Pain: Two Randomized,Single-Dose,Double-Blind,Placebo-Controlled Clinical Studies

Background

Paracetamol (APAP), also known as acetaminophen, is the most commonly used over-the-counter analgesic for the treatment of mild-to-moderate pain. However, the speed of onset of pain relief is limited mainly to the standard, immediate-release formulation. Efficacy and speed of onset of pain relief are critical in acute pain situations such as postsurgical dental pain, because reducing pain can improve clinical outcome and reduce the risk of transition from acute pain to more chronic pain. Efficacy and rapid onset also reduce the risk of excessive dosing with the analgesic.

Objective

We sought to investigate the dose–response efficacy and speed of onset of pain relief of a fast-dissolving APAP formulation compared with lower doses of APAP and placebo in dental patients after impacted third molar extraction.

Methods

Two single-center, single-dose, randomized, placebo-controlled, double-blind, double-dummy, parallel-group studies (Study I and Study II) were conducted to evaluate the efficacy and speed of onset of pain relief of different doses of a fast-dissolving APAP tablet (FD-APAP), standard APAP, and placebo in patients with postsurgical dental pain following third molar extraction. In Study I, a single dose of FD-APAP 1000 mg, FD-APAP 500 mg, or placebo was given to 300 patients; in Study II, a single dose of FD-APAP 1000 mg, standard APAP 650 mg, or placebo was given to 401 pateints. All 701 patients from both studies were included in the analysis and safety assessment.

Results

FD-APAP 1000 mg demonstrated significantly greater effect compared with FD-APAP 500 mg, APAP 650 mg, and placebo for all efficacy measurements, including sum of pain relief and pain intensity difference, total pain relief, sum of pain intensity difference, pain intensity difference, and pain relief score during 6 hours after the dose. Onset of confirmed first perceptible relief in subjects treated with FD-APAP 1000 mg was 15 minutes, which was 32% and 25% significantly shorter than onset of pain relief of FD-APAP 500 mg (22 minutes) and standard APAP 650 mg (20 minutes), respectively. FD-APAP 500 mg and APAP 650 mg demonstrated efficacy over placebo for most of the measurements; however, their effects were significantly lower and lasted for a shorter period of time than for FD-APAP 1000 mg. All study treatments were well tolerated.

Conclusions

FD-APAP 1000 mg tablets demonstrated efficacy over placebo. Also, FD-APAP 1000 mg had significantly superior effect, faster onset, and longer duration of pain relief compared with FD-APAP 500 mg and APAP 650 mg tablets. ClinicalTrials.gov identifiers: NCT01082081 and NCT01075243.
