Fluorescence immunoassays (FIA) have strong potential in enabling rapid quantitative immunological testing at point of care. Existing state of the art instruments employ laser scanning of FIA test kits, which require the use of electromechanical systems, making the instrument bulky, heavy and less reliable in the long term. There is a growing need for an extremely compact and reliable, motion-free, automated reader for accurate quantification of immunoassays. Here, we present ImQuant, an image based FIA reader with integrated monochromatic excitation source, optical filtering and real time image capture, assisted with an intuitive graphical user interface...

This study proposes a novel stair-climbing wheelchair based on lever propulsion control using the human upper body. Wheelchairs are widely used as supporting locomotion devices for people with acquired lower limb disabilities. However, steps and stairs are critical obstacles to locomotion, which restrict their activities when using wheelchairs. Previous research focused on power-assisted, stair-climbing wheelchairs, which were large and heavy due to its large actuators and mechanisms. In the previous research, we proposed a wheelchair with lever propulsion mechanism and presented its feasibility of climbing up the stairs...

BACKGROUND: Although various hand assist devices have been commercialized for people with paralysis, they are somewhat limited in terms of tool fixation and device attachment method. Hand exoskeleton robots allow users to grasp a wider range of tools but are heavy, complicated, and bulky owing to the presence of numerous actuators and controllers. The GRIPIT hand assist device overcomes the limitations of both conventional devices and exoskeleton robots by providing improved tool fixation and device attachment in a lightweight and compact device...

BACKGROUND: Given the increasing number of lead poisoning in opioids users and since no study has been conducted so far to review lead poisoning in methamphetamine (crystal) users, this study aimed to investigate blood lead level in methamphetamine addicts. METHODS: This study was conducted on 20 patients with methamphetamine poisoning and their blood lead level was measured. The subjects were selected from among patients with a history of continuous use of methamphetamine, without a history of using opiates in the past 6 months confirmed by a negative urine tests, and without a history of heavy metal poisoning...

INTRODUCTION: There is considerable interest in using brief measures of dependence for evaluation and treatment of tobacco dependence. The Heaviness of Smoking Index (HSI) is a validated measure of dependence among cigarette smokers. However, a similar index has not been studied among ST users. The aim of this study is to develop similar ST use indices and evaluate their utility as concise dependence measures. Time to first chew/dip of the day (TTFD), number of cans of ST used per week (CPW), and number of dips/chews per day (DPD) were used to create three ST use indices; heaviness of ST use index (HSTI), ST dependence index (STDI), and ST quantity frequency index (ST-QFI)...

BACKGROUND: Disinhibition is apparent in users of many substances, including heavy drinkers. Previous research has shown that brief training to improve inhibitory control is associated with reduced alcohol consumption. We investigated whether a new form of inhibitory training would produce greater reductions, relative to a carefully designed control condition and a proven method of reducing consumption, the Brief Alcohol Intervention (BAI). METHODS: One hundred and fourteen regular drinkers were assigned randomly to one of five training conditions: Control (no inhibitory training); Beer-NoGo (inhibit responses linked to task-irrelevant pictures of beer); Restrained-Stop (requiring more urgent inhibition but without pictures of beer); Combined (a previously untested form of training requiring urgent inhibition to pictures of beer); or BAI...

BACKGROUND: Alcohol dependent liver transplantation (LT) patients who resume alcohol are at risk for a number of alcohol related problems including liver injury and liver failure. Post LT patients are strongly advised to remain abstinent. However, we don't know how well this population complies due to a lack of valid methods (self-report and/or biomarkers) to identify alcohol use. Studies suggest as many as 50% resume alcohol use within 5 years. Phosphatidylethanol (PEth) is a new cell-membrane phospholipid biomarker to identify alcohol use in the past 28 days...

REVIEW

The concept of using a frameless intrauterine device (IUD) instead of the conventional plastic framed IUD is not new. Frameless copper IUDs have been available since the late 1990s. They rely on an anchoring system to retain in the uterine cavity. The clinical experience with these IUDs suggests that frameless IUDs fit better as they are thin and, therefore, do not disturb or irritate the uterus. High tolerance and continuation rates have been achieved as complaints of pain are virtually nonexistent and the impact on menstrual blood loss is minimal...

BACKGROUND: Frail older adults are heavy users of health and social care. In order to reduce the costs associated with frailty in older age groups, safe and cost-effective strategies are required that will reduce the incidence and severity of frailty. OBJECTIVE: We investigated whether self-reported intensity of physical activity (sedentary, mild, moderate or vigorous) performed at least once a week can significantly reduce trajectories of frailty in older adults who are classified as non-frail at baseline (Rockwood's Frailty Index [FI] ≤ 0...

Nancy Jo Kepple
BACKGROUND: Child maltreatment studies predominantly have operationalized parental substance use as dichotomous variables for any use, any harmful/risky use, or any substance use disorder (SUD). This limits our understanding about how a range of use behaviors may contribute to child maltreatment. OBJECTIVE: Build upon prior studies by incorporating a multi-faceted approach to operationalizing parental substance use. METHODS: Cross-sectional, secondary data analyses were conducted using the National Survey of Child and Adolescent Well-being (NSCAW I)...

REVIEW
Jane B Allendorfer, Jerzy P Szaflarski
Recent interest for the use of cannabis-derived products as therapeutic agents in the treatment of epilepsies has necessitated a reevaluation of their effects on brain and behavior. Overall, prolonged cannabis use is thought to result in functional and structural brain alterations. These effects may be dependent on a number of factors: e.g., which phytocannabinoid is used (e.g., cannabidiol (CBD) vs. tetrahyrocannabinol (THC)), the frequency of use (occasional vs. heavy), and at what age (prenatal, childhood, adulthood) the use began...
