Patterns of Pregabalin Users from Substance Abuse Treatment Facilities: Results from the French OPPIDUM Program from 2008 to 2022.

Introduction: In recent years, pregabalin has received growing attention due to its abuse liability. The aim of this study was to further characterize patterns of pregabalin users from substance abuse treatment facilities and detect changes in users profile over the study period.

Methods: The data source was the Observation des Produits Psychotropes Illicites ou Détournés de leur Utilisation Médicamenteuse (OPPIDUM) program, an annual, repeated, cross-sectional, nationwide, multicenter survey that collects consumption data from patients with substance use disorders.

Normal Routine Spirometry Can Mask COPD/Emphysema in Symptomatic Smokers.

Background: Recent studies have emphasized the difficulty of early detection of chronic obstructive pulmonary disease (COPD) in symptomatic smokers with normal routine spirometry. This includes post-bronchodilator normal forced expiratory volume in 1 second (FEV)(L)≥80% predicted, forced vital capacity (FVC)(L)≥80% predicted, and FEV/FVC ≥70% or greater than age corrected lower limit of normal (LLN). However, in COPD the pathologic site of small airway obstruction and emphysema begins in the small peripheral airways ≤2 mm id which normally contribute <20% of total airway resistance.

Validity of Social Support Scales Utilized Among HIV-Infected and HIV-Affected Populations: A Systematic Review.

Social support enhances self-management and prevention of behaviors and is typically assessed using self-report scales; however, little is known about the validity of these scales in HIV-infected or affected populations. This systematic review aims to identify available validated social support scales used in HIV-infected and HIV-affected populations. A systematic literature search using key search terms was conducted in electronic databases.

Further Studies of Unsuspected Emphysema in Nonsmoking Patients With Asthma With Persistent Expiratory Airflow Obstruction.

Background: Previously, we and other investigators have described reversible loss of lung elastic recoil in patients with acute and persistent, moderate-to-severe, chronic, treated asthma who never smoked, and its adverse effect on maximal expiratory airflow. In four consecutive autopsies, we reported the pathophysiologic mechanism(s) has been unsuspected mild, diffuse, middle and upper lobe centrilobular emphysema.

Methods: We performed prospective studies (5 to 22 years) in 25 patients (12 female) with chronic asthma, age 55 ± 15 years, who never smoked, with persistent moderate-to-severe expiratory obstruction.

Ecological momentary assessment for rehabilitation of chronic illness and disability.

Purpose: The main objectives of this manuscript were to provide a theoretical perspective on naturalistic delivery in rehabilitation based upon a literature review and establish a rationale for using ecological momentary assessment (EMA) for naturalistic assessment for chronic illness and disability (CID) in rehabilitation.

Method: Existing literature on EMA use across CID cohorts was gathered and analyzed to form a theoretical overview of implementation of this method in research. This review summarizes study results and provides a comprehensive literature table for greater analysis.

Thinking Forbidden Thoughts: The Oedipus Complex as a Complex of Knowing.

The Oedipus complex, considered by Freud the "nuclear complex of development," played a central role in the evolution of psychoanalytic thought. This paper returns to the point of transition from the seduction theory, Freud's initial theorem, to the oedipal model, and suggests that the Oedipus complex is first and foremost a text and as such contains a multiplicity of narratives. In particular, the author articulates the close relation between the Oedipus complex and the subject of knowing, postulating that underlying its surface level, the deep-level structure of this complex is one of knowing.

Biliary dyskinesia: a surgical disease rarely found outside the United States.

Background: Our objective was to determine if cholecystectomy for biliary dyskinesia (BD) was performed more commonly in the United States than in 4 comparator countries around the world.

Methods: Using the Nationwide Inpatient Sample, we extracted and analyzed data for cholecystectomy from 1991 to 2011 using ICD-9 (International Classification of Diseases 9th Revision) procedure codes. To derive the number of cholecystectomies performed for BD, we used the ICD-9 code 575.

Aphasia or Neglect after Thalamic Stroke: The Various Ways They may be Related to Cortical Hypoperfusion.

Although aphasia and hemispatial neglect are classically labeled as cortical deficits, language deficits or hemispatial neglect following lesions to subcortical regions have been reported in many studies. However, whether or not aphasia and hemispatial neglect can be caused by subcortical lesions alone has been a matter of controversy. It has been previously shown that most cases of aphasia or hemispatial neglect due to acute non-thalamic subcortical infarcts can be accounted for by concurrent cortical hypoperfusion due to arterial stenosis or occlusion, reversible by restoring blood flow to the cortex.

Combined effects of ultrasound and immobilization protocol on butyl acetate synthesis catalyzed by CALB.

It is well established that the performance of lipase B from Candida antarctica (CALB) as catalyst for esterification reactions may be improved by the use of ultrasound technology or by its immobilization on styrene-divinylbenzene beads (MCI-CALB). The present research evaluated the synthesis of butyl acetate using MCI-CALB under ultrasonic energy, comparing the results against those obtained using the commercial preparation, Novozym 435. The optimal conditions were determined using response surface methodology (RSM) evaluating the following parameters: reaction temperature, substrate molar ratio, amount of biocatalyst, and added water.

Ultrasound-assisted butyl acetate synthesis catalyzed by Novozym 435: enhanced activity and operational stability.

The influence of low-frequency ultrasound (40 kHz) in the esterification reaction between acetic acid and butanol for flavor ester synthesis catalyzed by the commercial immobilized lipase B from Candida antarctica (Novozym 435) was evaluated. A central composite design and the response surface methodology were used to analyze the effects of the reaction parameters (temperature, substrate molar ratio, enzyme content and added water) and their response (yields of conversion in 2.5 h of reaction).

Heart rate turbulence during acute alcohol withdrawal syndrome.

Background: Alcohol withdrawal syndrome is associated with an increased incidence of cardiac arrhythmias and sudden cardiac death. Heart rate turbulence (HRT) parameters were applied during withdrawal to estimate cardiac regulation during treatment with clomethiazole.

Methods: Twenty-two patients suffering from alcohol withdrawal syndrome were included in the study.

Central and peripheral airway sites of nitric oxide gas exchange in COPD.

Background: This study investigated sites of nitric oxide (NO) gas exchange and response to inhaled corticosteroids (ICS) in patients with COPD and varying extents of emphysema.

Methods: This was a prospective, randomized, single-blind, crossover study in treated, stable, ex-smoking patients with COPD who were ICS and leukotriene receptor antagonists naive. Lung function, high-resolution thin-section CT scan of the lung, and exhaled NO were measured at 50, 100, 150, and 200 mL/s.

Tiotropium induced bronchodilation and protection from dynamic hyperinflation is independent of extent of emphysema in COPD.

Background: The magnitude of tiotropium (1) induced bronchodilation and (2) protection against dynamic hyperinflation in COPD phenotypes has not been studied.

Methods: We studied moderate to severe COPD patients with varying extent of emphysema as evaluated by high-resolution thin-section lung CT. Spirometry including inspiratory capacity (IC) was measured before and immediately after metronome paced hyperventilation (MPH) at 2 times resting respiratory rate for 20s to induce dynamic hyperinflation.

Treating hypertension in type II diabetic patients with device-guided breathing: a randomized controlled trial.

The objective of the study was to evaluate the efficacy of device-guided breathing to lower blood pressure (BP) in hypertensive type II diabetic patients. A randomized controlled trial was carried out in four urban family practice clinics in Israel. Non-insulin-dependent diabetic, hypertensive patients with uncontrolled BP, receiving antihypertensive therapy or those non-medicated were enrolled.
