Q: Context: Allopregnanolone (ALLO) is a physiologically relevant neurosteroid modulator of GABA(A) receptors, and it exhibits a psychopharmacological profile that closely resembles the post-ingestive effects of ethanol. The 5alpha-reductase inhibitor finasteride (FIN), which inhibits biosynthesis of ALLO and structurally related neurosteroids, was previously demonstrated to reduce the maintenance of limited-access ethanol consumption. The primary aim of the current work was to determine whether FIN would reduce the acquisition of drinking in ethanol-naive mice.', 'Male C57BL/6J (B6) mice were acclimated to a reverse light/dark schedule, and were provided ad libitum access to chow and water. Following habituation to vehicle injections (VEH; 20% w/v beta-cyclodextrin; i.p.) administered 22-hour prior to drinking sessions with water only, mice were divided into 3 treatment groups: vehicle control (VEH), 50 mg/kg FIN (FIN-50), and 100 mg/kg FIN (FIN-100). Twenty-two hours after the first treatment, mice were permitted the inaugural 2-hour limited access to a 10% v/v ethanol solution (10E) and water. The acquisition of 10E consumption and underlying drinking patterns were assessed during FIN treatment (7 days) and subsequent FIN withdrawal (13 days) phases.', 'FIN dose-dependently blocked the acquisition of 10E drinking and prevented the development of ethanol preference, thereby suggesting that the GABAergic neurosteroids may be important in the establishment of stable drinking patterns. FIN-elicited reductions in 10E intake were primarily attributable to selective and marked reductions in bout frequency, as no changes were observed in bout size, duration, or lick rates following FIN treatment. FIN-treated mice continued to exhibit attenuated ethanol consumption after 2 weeks post-treatment, despite a full recovery in brain ALLO levels. A second study confirmed the rightward and downward shift in the acquisition of ethanol intake following 7 daily FIN injections. While there were no significant group differences in brain ALLO levels following the seventh day of ethanol drinking, ALLO levels were decreased by 28% in the FIN-50 group.
Answer: Although the exact mechanism is unclear, FIN and other pharmacological interventions that modulate the GABAergic system may prove useful in curbing ethanol intake acquisition in at-risk individuals.

Q: Context: The normal anterior translation of the articular surface of the distal humerus with respect to the humeral diaphysis facilitates elbow flexion. We hypothesize that there is a correlation between anterior translation of the distal humeral articular surface and flexion after open reduction and internal fixation (ORIF) of a fracture of the distal humerus.', 'Two independent observers evaluated 141 lateral radiographs of patients more than 6 months after fracture of the distal humerus and 155 lateral radiographs of patients without injury of the distal humerus. The distance between the most anterior point of the distal humerus articular surface, perpendicular to the humeral shaft, from the anterior border of the distal part of the humeral diaphysis, was measured on lateral radiographs as a percentage of the width of the humeral shaft.', 'The technique of measuring anterior translation of the distal humeral articular surface had good intra- and interobserver reliability. The most anterior point of the distal humeral articular surface lies an average of 11.7 mm (range, 6.8 to 17.0 mm) in front of the most anterior border of the humeral shaft in normal distal humeri, which represents 62% of the humeral shaft diameter (range, 33% to 91%). There was a limited but significant correlation between flexion and anterior translation as a percentage of the humeral shaft diameter in distal humeri after fracture that was maintained in multivariable statistical models.
Answer: Using a reproducible technique for measuring anterior translation of the distal humerus, there was a correlation between anterior translation of the distal humeral articular surface and elbow flexion after ORIF. Although the weakness of the correlation emphasizes that limitation of elbow flexion after ORIF of a distal humerus fracture is multifactorial, reduced anterior translation of the distal humeral articular surface might be a contributing factor.

A: Is loss of anterior translation of the distal humeral articular surface associated with decreased elbow flexion?

Q: Context: Associations between multidrug resistance and the Mycobacterium tuberculosis Beijing genotype have been described mainly in populations with poor tuberculosis (TB) control such as prisons and inner cities, and may reflect shared risk factors rather than a biological association.', 'To study the association between genotype and drug resistance among TB patients in a population with adequate TB control.', 'Three rural districts in Vietnam. The study was performed at the Pham Ngoc Thach Tuberculosis and Lung Disease Hospital, Ho Chi Minh City, and the Tien Giang Provincial Tuberculosis and Lung Disease Hospital, My Tho, Vietnam.', 'Pretreatment sputum specimens were collected for culture, drug susceptibility testing and spoligotyping of all sputum smear-positive pulmonary TB patients consecutively diagnosed over a 3-year period.', 'Beijing genotype infections were observed in 614 of 1744 (35%) patients. Beijing strains were more common among female (adjusted odds ratio [aOR] 1.4, P = 0.005), young (aOR 2.8, P < 0.001) and previously treated patients (aOR 2.4, P < 0.001). The Beijing genotype was associated with any resistance (aOR 3.7, P < 0.001) and multidrug resistance (aOR 6.8, P < 0.001) among new patients, and with any resistance (aOR 2.7, P = 0.005) but not with multidrug resistance (aOR 1.4, P = 0.545) among previously treated patients.
Answer: In Vietnam, Beijing genotype is associated with young age and in new patients with multidrug resistance despite adequate TB control, suggesting a biological association. This potentially undermines the effectiveness of TB control in countries where Beijing genotype infections are common.

Is the Beijing genotype associated with young age and multidrug-resistant tuberculosis in rural Vietnam?
