The Adult JUUL Switching and Smoking Trajectories (ADJUSST) Study: Methods and Analysis of Loss-to-Follow-up.

The Adult JUUL System User Switching and Smoking Trajectories (ADJUSST) study assessed the smoking and JUUL use trajectories of adults who purchased JUUL. In this paper, we describe study methods, characterize the sample, and assesses potential for bias due to loss to follow-up. We entered 55,414 US adults (≥ age 21) who purchased a JUUL Starter Kit for the first time (online or at retail) in 2018 into a naturalistic, longitudinal observational study, irrespective of baseline smoking status.

Sources of youth access to JUUL vaping products in the United States.

Introduction: This study assessed sources of youth access to JUUL vaping products, the highest selling brand of the most commonly used tobacco product among adolescents in the United States.

Methods: A cross-sectional online survey assessed use of JUUL vaping products in a non-probability, nationally representative sample of 9865 adolescents aged 13-17 years in the United States. Past 30-day JUUL users (n = 1537) were asked how they got the JUUL vaping products they had used in the past 30-days.

Factors associated with past 30-day abstinence from cigarette smoking in adult established smokers who used a JUUL vaporizer for 6 months.

Background: JUUL is the fastest growing and highest selling brand of e-cigarette/vapor products in the USA. Assessing the effect of JUUL vapor products on adult smokers' use of conventional tobacco cigarettes can help inform the potential population health impact of these products.

Methods: Participants were 15,456 US adult established current smokers aged 21 years who had purchased their first JUUL Starter Kit from a retail store or online within the past 7 days.

Factors associated with past 30-day abstinence from cigarette smoking in a non-probabilistic sample of 15,456 adult established current smokers in the United States who used JUUL vapor products for three months.

Background: JUUL is the fastest growing and highest selling brand of e-cigarette/vapor products in the USA. Assessing the effect of JUUL vapor products on adult smokers' use of conventional tobacco cigarettes can help inform the potential population health impact of these products.

Methods: Online surveys assessed past 30-day use of conventional cigarettes, JUUL vapor products, and other e-cigarettes/vapor products, monthly for 3 months, in a non-probabilistic sample of 15,456 US adults (21+ years).

The Value of Providing Smokers with Free E-Cigarettes: Smoking Reduction and Cessation Associated with the Three-Month Provision to Smokers of a Refillable Tank-Style E-Cigarette.

Despite the uptake of tobacco smoking declining in the United Kingdom (UK), smoking is still the leading cause of preventable poor health and premature death. While improved approaches to smoking cessation are necessary, encouraging and assisting smokers to switch by using substantially less toxic non-tobacco nicotine products may be a possible option. To date, few studies have investigated the rates of smoking cessation and smoking reduction that are associated with the provision of free electronic-cigarettes (e-cigarettes) to smokers.

Relationship between trying an electronic cigarette and subsequent cigarette experimentation in Scottish adolescents: a cohort study.

Background: This study examines whether young never smokers in Scotland, UK, who have tried an e-cigarette are more likely than those who have not, to try a cigarette during the following year.

Methods: Prospective cohort survey conducted in four high schools in Scotland, UK during February/March 2015 (n=3807) with follow-up 1 year later. All pupils (age 11-18) were surveyed.

Relationship between e-cigarette point of sale recall and e-cigarette use in secondary school children: a cross-sectional study.

Background: There has been a rapid increase in the retail availability of e-cigarettes in the UK and elsewhere. It is known that exposure to cigarette point-of-sale (POS) displays influences smoking behaviour and intentions in young people. However, there is as yet no evidence regarding the relationship between e-cigarette POS display exposure and e-cigarette use in young people.

"It Looks Like an Adult Sweetie Shop": Point-of-Sale Tobacco Display Exposure and Brand Awareness in Scottish Secondary School Students.

Introduction: As further restrictions have been placed on tobacco advertising and promotions, point-of-sale (PoS) displays of cigarettes in shops have become an increasingly important source of young people's exposure to tobacco products. This study explored the relationship between PoS displays of cigarettes and brand awareness among secondary school students in Scotland.

Methods: Cross-sectional school surveys (n = 1406) and focus groups (n = 86) were conducted with S2 (13-14 years) and S4 (15-16 years) students in four schools of differing socioeconomic status in 2013, prior to the PoS display ban in large shops.

A randomised controlled trial to evaluate the efficacy of a 6-month dietary and physical activity intervention for patients receiving androgen deprivation therapy for prostate cancer.

Purpose: Treatment of prostate cancer with androgen deprivation therapy (ADT) is associated with an increased fat mass, decreased lean mass, increased fatigue and a reduction in quality of life (QoL). The aim of this study was to evaluate the efficacy of a 6-month dietary and physical activity intervention for prostate cancer patients receiving ADT, to help minimise these side effects.

Methods: Patients (n = 94) were recruited to this study if they were planned to receive ADT for prostate cancer for at least 6 months.

The effect of dietary and exercise interventions on body weight in prostate cancer patients: a systematic review.

Prostate cancer prognosis may therefore be improved by maintaining healthy weight through diet and physical activity. This systematic review looked at the effect of diet and exercise interventions on body weight among men treated for prostate cancer. MEDLINE, EMBASE, CINAHL, and Cochrane Library databases were searched from the earliest record to August 2013.

Relational mechanisms and psychological outcomes in couples affected by breast cancer: a systematic narrative analysis of the literature.

Introduction: Relationships are a significant dimension of illness experience. At the couple level, partners will respond to illness as an interpersonal unit rather than individuals in isolation. Research adopting a relational perspective have focused on communication, relational coping and relationship functioning and satisfaction.

Agriculture for improved nutrition: the current research landscape.

Background: Concern about food security and its effect on persistent undernutrition has increased interest in how agriculture could be used to improve nutritional outcomes in developing countries. Yet the evidence base for the impact of agricultural interventions targeted at improved nutrition is currently poor.

Objective: To map the extent and nature of current and planned research on agriculture for improved nutrition in order to identify gaps where more research might be useful.

Iron-containing micronutrient powder provided to children with moderate-to-severe malnutrition increases hemoglobin concentrations but not the risk of infectious morbidity: a randomized, double-blind, placebo-controlled, noninferiority safety trial.

Background: A link between the provision of iron and infectious morbidity has been suggested, particularly in children with malnutrition. Two meta-analyses concluded that iron is not harmful, but malnourished children were underrepresented in most available studies.

Objective: This study evaluated the effect of iron-containing micronutrient powder (iron MNP) on infectious morbidities when provided to children with moderate-to-severe malnutrition and anemia.

A randomised controlled trial to evaluate the efficacy of a 6 month dietary and physical activity intervention for prostate cancer patients receiving androgen deprivation therapy.

Background: Treatment with Androgen Deprivation Therapy (ADT) for prostate cancer is associated with changes in body composition including increased fat and decreased lean mass; increased fatigue, and a reduction in quality of life. No study to date has evaluated the effect of dietary and physical activity modification on the side-effects related to ADT. The aim of this study is to evaluate the efficacy of a 6-month dietary and physical activity intervention for prostate cancer survivors receiving ADT to minimise the changes in body composition, fatigue and quality of life, typically associated with ADT.

The effect of androgen deprivation therapy on body composition in men with prostate cancer: systematic review and meta-analysis.

Introduction: The use of androgen deprivation therapy (ADT) in the treatment of prostate cancer is associated with changes in body composition including increased fat and decreased lean mass. Limited information exists regarding the rate and extent of these changes. This systematic review was conducted to determine the effects of ADT on body composition in prostate cancer patients.

A multiple-micronutrient-fortified beverage affects hemoglobin, iron, and vitamin A status and growth in adolescent girls in rural Bangladesh.

Adolescent girls have high nutrient needs and are susceptible to micronutrient deficiencies. The objective of this study was to test the effect of a multiple-micronutrient-fortified beverage on hemoglobin (Hb) concentrations, micronutrient status, and growth among adolescent girls in rural Bangladesh. A total of 1125 girls (Hb > or = 70 g/L) enrolled in a randomized, double-blind, placebo-controlled trial and were allocated to either a fortified or nonfortified beverage of similar taste and appearance.

Effect of daily versus once-weekly home fortification with micronutrient Sprinkles on hemoglobin and iron status among young children in rural Bangladesh.

Background: The effectiveness of commonly suggested public health interventions to control childhood iron-deficiency anemia has been low.

Objective: To determine whether iron provided in Sprinkles daily or in a higher dose once weekly affected hemoglobin, serum ferritin levels, and serum transferrin receptor levels, and to determine whether there were differences in the effects of the two regimens.

Methods: In this cluster-randomized, community-based trial conducted in rural areas of Bangladesh, 136 children aged 12 to 24 months with mild to moderate anemia (hemoglobin 70-109 g/L) were randomly allocated to receive Sprinkles daily (12.

Change in food and energy consumption among the ultra poor: is the poverty reduction programme making a difference?

Background: Poverty persists at an alarming level in Bangladesh. To reduce extreme poverty and create the foundation for a sustainable livelihood change, BRAC undertook a targeted programme since 2002 named, Challenging the Frontiers of Poverty Reduction/Targeting the Ultra Poor (CFPR/TUP).

Objective: To investigate the impact of the CFPR/TUP programme on food and energy consumption.
