Most frequently reported AEs included dizziness, dry mouth, nausea and constipation. Pregabalin had a higher risk of somnolence (RR 3.15, 95% CI 2.00-4.98) and dizziness (RR 2.9, 95% CI 1.58-5.30). Ketamine had a higher risk of reduced vision (RR 9.00, 95% CI 0.05-146.11), dizziness (RR 8.33, 95% CI 1.73-40.10) and somnolence (RR 7.00, 95% CI 1.73-40.1). WRs ranged from 18.4% (antidepressants), 0-30% (anticonvulsants), 0-10% (anti-spasticity), 0-48% (analgesics), 28.6% (cannabinoids) and 0-22.2% (other).

Pregabalin was found to be effective for NP versus placebo. Cannabinoids was ineffective for NP. AEs are a common cause for withdrawal. The nature of AEs was poorly reported and should be improved in future RCT's.

We used porcine oocytes as an experimental model to study the effect of HU during oocyte maturation. Exposure of cumulus-oocyte complexes (COCs) to 20 µM (P less then 0.01) and 50 µM (P less then 0.001) HU reduced oocyte maturation. Exposure to 20 µM HU induced approximately 1.5- and 2-fold increases in Caspase-3 (P less then 0.001) and P53 (P less then 0.01) gene expression levels in cumulus cells, respectively, increased Caspase-3 (P less then 0.01) and P53 (P less then 0.001) protein expression levels in metaphase II (MII) oocytes and increased the percentage of apoptotic cumulus cells (P less then 0.001). In addition, HU decreased the mitochondrial membrane potential (Δφm) (P less then 0.01 and P less then 0.001) and glutathione (GSH) levels (P less then 0.01 and P less then 0.001) of both cumulus cells and MII oocytes, while increasing their reactive oxygen species (ROS) levels (P less then 0.001). Following parthenogenetic activation of embryos derived from MII oocytes, exposure to 20 µM HU significantly reduced total blastocyst cell numbers (P less then 0.001) and increased apoptosis of blastocyst cells (P less then 0.001). Moreover, HU exposure reduced the rate of development of two-celled, four- to eight-celled, blastocyst, and hatching stages after parthenogenetic activation (P less then 0.05). Our findings indicate that exposure to 20 µM HU caused significant oxidative stress and apoptosis of MII oocytes during maturation, which affected their developmental ability. These results provide valuable information for safety assessments of HU.

Smokeless tobacco (ST) is a significant South Asian public health problem. This paper reports a qualitative study of a sample of South Asian ST users.

Interviews, using a piloted topic guide, with 33 consenting, urban dwelling adult ST users explored their ST initiation, continued use and cessation attempts. Framework data analysis was used to analyse country specific data before a thematic cross-country synthesis was completed.

Participants reported long term ST use and high dependency. All reported strong cessation motivation and multiple failed attempts because of ease of purchasing ST, tobacco dependency and lack of institutional support.

Interventions to support cessation attempts amongst consumers of South Asian ST products should address the multiple challenges of developing an integrated ST policy, including cessation services.

This study provides detailed understanding of the barriers and drivers to ST initiation, use and cessation for users in Bangladesh, India and Pakistan. It is the first study to directly compare these three countries. The insight was then used to adapt an existing behavioural support intervention for ST cessation for testing in these countries.

Reducing light smoking is a challenge because it is unclear why some but not others, progress to heavier smoking. KN-93 Nicotine has profound effects on brain reward systems and individual differences in nicotine's reward-enhancing effects may drive variability in smoking trajectories. Therefore, we examined whether a genetic risk factor and personality traits known to moderate reward processing, also moderate the reward-enhancing effects of nicotine. Light smokers (n=116) performed a Probabilistic Reward Task to assess reward responsiveness after receiving either nicotine or placebo (order counterbalanced). Individuals were classified as nicotine dependence 'risk' allele carriers (rs16969968 A-allele carriers) or non-carriers (non-A-allele carriers), and self-reported negative affective traits were also measured. Across the whole sample, reward responsiveness was greater following nicotine compared to placebo (p=0.045). For Caucasian A-allele carriers but not non-A-allele carriers, nicotine enhanced reward responsiveness compared to placebo for those who received the placebo first (p=0.010). Furthermore, for A-allele carriers but not non-A-allele carriers who received nicotine first, the enhanced reward responsiveness in the nicotine condition carried over to the placebo condition (p less then 0.001). Depressive traits also moderated the reward-enhancing effects of nicotine (p=0.010) and were associated with more blunted reward responsiveness following placebo but enhanced reward responsiveness following nicotine. These findings suggest that individual differences in a genetic risk factor and depressive traits alter nicotine's effect on reward responsiveness in light smokers and may be important factors underpinning variability in smoking trajectories in this growing population.The back squat is one of the most effective exercises in strengthening the muscles of the lower extremity. Understanding the impact of footwear has on the biomechanics is imperative for maximizing the exercise training potential, preventing injury, and rehabilitating from injury. This review focuses on how different types of footwear affect the full-body kinematics, joint loads, muscle activity, and ground reaction forces in athletes of varying experience performing the weighted back squat. The literature search was conducted using three databases, and fourteen full-text articles were ultimately included in the review. The majority of these studies demonstrated that the choice of footwear directly impacts kinematics and kinetics. Weightlifting shoes were shown to decrease trunk lean and generate more plantarflexion relative to running shoes and barefoot lifting. Elevating the heel through the use of external squat wedges is popular method during rehabilitation and was shown to provide similar effects to weightlifting shoes.
