Cannabidiol reverses attentional bias to cigarette cues in a human experimental model of tobacco withdrawal

Background and Aims

Cannabidiol (CBD), a non‐intoxicating cannabinoid found in cannabis, may be a promising novel smoking cessation treatment due to its anxiolytic properties, minimal side effects and research showing that it may modify drug cue salience. We used an experimental medicine approach with dependent cigarette smokers to investigate if (1) overnight nicotine abstinence, compared with satiety, will produce greater attentional bias (AB), higher pleasantness ratings of cigarette‐related stimuli and increased craving and withdrawal; and (2) CBD in comparison to placebo, would attenuate AB, pleasantness of cigarette‐related stimuli, craving and withdrawal and not produce any side effects.

Design

Randomized, double‐blind cross‐over study with a fixed satiated session followed by two overnight abstinent sessions.

Setting

UK laboratory.

Participants

Thirty non‐treatment‐seeking, dependent cigarette smokers recruited from the community.

Intervention and comparator

800 mg oral CBD, or matched placebo (PBO) in a counterbalanced order

Measurements

AB to pictorial tobacco cues was recorded using a visual probe task and an explicit rating task. Withdrawal, craving, side effects, heart rate and blood pressure were assessed repeatedly.

Findings

When participants received PBO, tobacco abstinence increased AB (P = 0.001, d = 0.789) compared with satiety. However, CBD reversed this effect, such that automatic AB was directed away from cigarette cues (P = 0.007, d = 0.704) and no longer differed from satiety (P = 0.82). Compared with PBO, CBD also reduced explicit pleasantness of cigarette images (P = 0.011; d = 0.514). Craving (Bayes factor = 7.08) and withdrawal (Bayes factor = 6.95) were unaffected by CBD, but greater in abstinence compared with satiety. Systolic blood pressure decreased under CBD during abstinence.

Conclusions

A single 800‐mg oral dose of cannabidiol reduced the salience and pleasantness of cigarette cues, compared with placebo, after overnight cigarette abstinence in dependent smokers. Cannabidiol did not influence tobacco craving or withdrawal or any subjectively rated side effects.     

Medications That Cause Dry Mouth As an Adverse Effect in Older People: A Systematic Review and Metaanalysis

Objectives

To assess and quantify the risk of drug‐induced dry mouth as a side effect in older people.

Design

Systematic review and metaanalysis.

Setting

A search of the literature was undertaken using Medline, Embase, Cochrane, Web of Science, and PubMed from 1990 to 2016.

Participants

Older people (aged ≥60) who participated in intervention or observational studies investigating drug use as an exposure and xerostomia or salivary gland hypofunction as adverse drug outcomes.

Measurements

Two pairs of authors screened titles and abstracts of studies for relevance. Two authors independently extracted data, including study characteristics, definitions of exposure and outcome, and methodological quality. For the metaanalyses, random‐effects models were used for pooling the data and I² statistics for exploring heterogeneity.

Results

Of 1,544 potentially relevant studies, 52 were deemed eligible for inclusion in the final review and 26 in metaanalyses. The majority of studies were of moderate methodological quality. In the intervention studies, urological medications (odds ratio (OR) = 5.91, 95% confidence interval (CI) = 4.04–8.63; I² = 62%), antidepressants (OR = 4.74, 95% CI = 2.69–8.32, I² = 21%), and psycholeptics (OR = 2.59, 95% CI = 1.79–3.95, I² = 0%) were significantly associated with dry mouth. In the observational studies, numbers of medications and several medication classes were significantly associated with xerostomia and salivary gland hypofunction.

Conclusion

Medication use was significantly associated with xerostomia and salivary gland hypofunction in older adults. The risk of dry mouth was greatest for drugs used for urinary incontinence. Future research should develop a risk score for medication‐induced dry mouth to assist with prescribing and medication management.     

Gender differences in individuals with obesity and binge eating disorder: A retrospective comparison of phenotypical features and treatment outcomes

Objective

Phenotypical comparisons between individuals with obesity without binge eating disorder (OB) and individuals with obesity and comorbid binge eating disorder (OB + BED) are subject to ongoing investigations. At the same time, gender-related differences have rarely been explored, raising the question whether men and women with OB and OB + BED may require differently tailored treatments.

Method

We retrospectively compared pre- versus post-treatment data in a matched sample of n = 180 men and n = 180 women with OB or OB + BED who received inpatient treatment.

Results

We found that men displayed higher weight loss than women independent of diagnostic group. In addition, men with OB + BED showed higher weight loss than men with OB after 7 weeks of treatment.

Conclusions

The present findings add to an emerging yet overall still sparse body of studies comparing phenotypical features and treatment outcomes in men and women with OB and OB + BED; implications for further research are discussed.

Clinical Trial Registration

The study was prospectively registered with the German Clinical Trial Register as part of application DRKS00028441.     

Syncope,Hypotension, and Falls in the Treatment of Hypertension: Results from the Randomized Clinical Systolic Blood Pressure Intervention Trial

Objective

To determine predictors of serious adverse events (SAEs) involving syncope, hypotension, and falls, with particular attention to age, in the Systolic Blood Pressure Intervention Trial.

Design

Randomized clinical trial.

Setting

Academic and private practices across the United States (N = 102).

Participants

Adults aged 50 and older with a systolic blood pressure (SBP) of 130 to 180 mmHg at high risk of cardiovascular disease events, but without diabetes, history of stroke, symptomatic heart failure or ejection fraction less than 35%, dementia, or standing SBP less than 110 mmHg (N = 9,361).

Intervention

Treatment of SBP to a goal of less than 120 mmHg or 140 mmHg.

Measurements

Outcomes were SAEs involving syncope, hypotension, and falls. Predictors were treatment assignment, demographic characteristics, comorbidities, baseline measurements, and baseline use of cardiovascular medications.

Results

One hundred seventy‐two (1.8%) participants had SAEs involving syncope, 155 (1.6%) hypotension, and 203 (2.2%) falls. Randomization to intensive SBP control was associated with greater risk of an SAE involving hypotension (hazard ratio (HR) = 1.67, 95% confidence interval (CI) = 1.21–2.32, P = .002), and possibly syncope (HR = 1.32, 95% CI = 0.98–1.79, P = .07), but not falls (HR = 0.98, 95% CI = 0.75–1.29, P = .90). Risk of all three outcomes was higher for participants with chronic kidney disease or frailty. Older age was also associated with greater risk of syncope, hypotension, and falls, but there was no age‐by‐treatment interaction for any of the SAE outcomes.

Conclusions

Participants randomized to intensive SBP control had greater risk of hypotension and possibly syncope, but not falls. The greater risk of developing these events associated with intensive treatment did not vary according to age.     

Childhood traumatic experiences and the association with marijuana and cocaine use in adolescence through adulthood

Background and aims

Examination of longitudinal relationships between childhood traumatic experiences and drug use across the life‐course at the national level, with control of confounding by other forms of trauma, is needed. We aimed to estimate the prevalence of nine typologies of childhood traumas and the cumulative number experienced, correlation between traumas and associations between individual and cumulative number of traumas with drug use during adolescence, emerging adulthood and adulthood.

Design

Secondary data analysis using the National Longitudinal Study of Adolescent to Adult Health.

Setting

United States.

Participants

A nationally representative sample of individuals in grades 7–12 (aged 11–21 years) during 1994–95, who were re‐interviewed during emerging adulthood (2001–02; aged 18–28) and adulthood (2007–08; aged 24–34). The analytical sample comprised 12 288 participants with data at all three waves.

Measurements

Nine typologies of childhood traumas: neglect; emotional, physical and sexual abuse; parental incarceration and binge drinking; and witnessing, being threatened with and experiencing violence. Indicators of each were summed to measure cumulative dose. Outcomes were marijuana and cocaine use during adolescence, emerging adulthood and adulthood.

Findings

Approximately half experienced at least one childhood trauma; traumas were not highly correlated. We observed a dose–response relationship between the number of traumas and drug use in adolescence [marijuana, adjusted odds ratio (aOR) one trauma versus none = 1.65, 95% confidence interval (CI) = 1.42, 1.92; two traumas = 2.58, 95% CI = 2.17, 3.06; ≥ four traumas = 6.92, 95% CI = 5.17, 9.26; cocaine, aOR one trauma = 1.87, 95% CI = 1.23, 2.84; two traumas = 2.80, 95% CI = 1.74, 4.51; ≥ four traumas = 9.54, 95% CI = 5.93, 15.38]. Similar dose–response relationships with drug use were observed in emerging adulthood and adulthood. Each individual trauma was associated independently with either marijuana or cocaine use in adolescence, emerging adulthood and/or adulthood.

Conclusions

Childhood trauma is prevalent in the United States, and individual types as well as the total number experienced are associated significantly with marijuana and cocaine use throughout the life‐course.     

Effects of comorbid substance use disorders on outcomes in a Housing First intervention for homeless people with mental illness

Background and Aims

Evidence supports the effectiveness of Housing First (HF) programmes for people who are experiencing homelessness and mental illness; however, questions remain about its use in people with comorbid substance use disorders (SUD). The aim of this project was to test whether SUD modifies the effectiveness of an HF intervention.

Design

Secondary analysis of data from a randomized controlled trial of HF versus treatment‐as‐usual (TAU) with 24‐month follow‐up, comparing those with and without SUD at trial entry.

Setting

Vancouver, Toronto, Winnipeg, Moncton and Montreal, Canada.

Participants

A total of 2154 participants recruited from 2009 to 2013 and randomized to HF versus TAU (67% male, mean age 40.8 ± 11.2, 25% ethno‐cultural minority). All were homeless and had a mental disorder at baseline; 35% reported symptoms consistent with SUD.

Intervention

Housing paired with Intensive Case Management or Assertive Community Treatment.

Measurements

Primary outcomes were days housed and community functioning. Secondary outcomes were general and health‐related quality of life and mental health symptoms. Predictors were SUD status crossed with intervention group (HF versus TAU).

Findings

People with SUD in both the HF and TAU groups spent less time in stable housing, but the effect of HF did not vary by SUD status [odds ratio (OR) = 1.17, 95% confidence interval (CI) = ?0.77, 1.76]. Similarly, there was no difference between those with and without SUD in the effect of HF (over TAU) on community functioning (b = 0.75, 95% CI = ?0.36, 1.87), quality of life (b = ?1.27, 95% CI = ?4.17, 1.63), health‐related quality of life (b = ?0.01, 95% CI = ?0.03, 0.02) or mental health symptoms (b = 0.43, 95% CI = ?0.99, 1.86).

Conclusions

Housing First programs in Canada are equally effective in people with and without comorbid substance use disorder (SUD). Overall, the intervention appears to be able to engage people with SUD and is reasonably successful at housing them, without housing being contingent upon abstinence or treatment.     

Education is the strongest socio‐economic predictor of smoking in pregnancy

Aims

To investigate socio‐economic disparities in smoking in pregnancy (SIP) by the mother's education, occupational class and current economic conditions.

Design

Cross‐sectional analysis with linked survey and register data.

Setting

South‐western Finland.

Participants

A total of 2667 pregnant women [70% of the original sample (n = 3808)] from FinnBrain, a prospective pregnancy cohort study.

Measurements

The outcome was smoking during the first pregnancy trimester, measured from the Finnish Medical Birth Register. Education and occupational class were linked from population registers. Income support recipiency and subjective economic wellbeing were questionnaire‐based measures of current economic conditions. These were adjusted for age, partnership status, residential area type, parental separation, parity, childhood socio‐economic background, childhood adversities (the Trauma and Distressing Events During Childhood scale) and antenatal stress (Edinburgh Postnatal Depression Scale). Logistic regressions and attributable fractions (AF) were estimated.

Findings

Mother's education was the strongest socio‐economic predictor of SIP. Compared with university education, adjusted odds ratios (aORs) of SIP were: 2.2 [95% confidence interval (CI) = 1.2–3.9; P = 0.011] for tertiary vocational education, 4.4 (95% CI = 2.1–9.0; P < 0.001) for combined general and vocational secondary education, 2.9 (95% CI = 1.4–6.1; P = 0.006) for general secondary education, 9.5 (95% CI 5.0–18.2; P < 0.001) for vocational secondary education and 14.4 (95% CI = 6.3–33.0; P < 0.001) for compulsory schooling. The total AF of education was 0.5. Adjusted for the other variables, occupational class and subjective economic wellbeing did not predict SIP. Income support recipiency was associated positively with SIP (aOR = 1.8; 95% CI = 1.1–3.1; P = 0.022). Antenatal stress predicted SIP (aOR = 2.0; 95% CI = 1.4–2.8; P < 0.001), but did not attenuate its socio‐economic disparities.

Conclusions

In Finland, socio‐economic disparities in smoking in pregnancy are attributable primarily to differences in the mother's educational level (low versus high) and orientation (vocational versus general).     

New Institutionalization in Long‐Term Care After Hospital Discharge to Skilled Nursing Facility

Background/Objectives

Approximately half of individuals newly admitted to long‐term care (LTC) nursing homes (NHs) experienced a prior hospitalization followed by discharge to a skilled nursing facility (SNF). The objective was to examine characteristics associated with new institutionalizations of older adults on this care trajectory.

Design

Retrospective cohort study.

Setting

SNFs and LTC NHs.

Patients

Medicare fee‐for‐service beneficiaries admitted to 7,442 SNFs in 2013 (N = 597,986).

Measurements

We used demographic and clinical characteristics from Medicare data and the Minimum Data Set. We defined “new institutionalization” as LTC NH residence for longer than 90 non‐SNF days, starting within 6 months of hospital discharge.

Results

For individuals who survived 6 months after hospital discharge, the overall rate of new LTC institutionalizations was 10.0% (N = 59,736). Older age, white race, being unmarried, Medicaid eligibility, higher income, more comorbidities, cognitive impairment, depression, functional limitations, hallucinations and delusions, aggressive behavior, incontinence, and pressure ulcers were associated with higher adjusted odds of new LTC institutionalization. In analyses stratified according to race and ethnicity, higher income was associated with lower odds of LTC institutionalization for whites (odds ratio (OR) = 0.92, 95% confidence interval (CI) = 0.89–0.96) and greater odds for blacks (OR = 1.40, 95% CI = 1.27–1.55) and Hispanics (OR = 1.44, 95% CI = 1.25–1.66). Moderate or severe depression, functional limitations, hallucinations and delusions, aggressive behavior, and being unmarried were stronger risk factors for LTC for cognitively intact individuals than for those with moderate to severe cognitive impairment. Being unmarried and having more comorbidities were stronger predictors in those aged 66 to 70 than in those aged 81 to 85 and 91 and older.

Conclusion

Associations between risk factors and new LTC institutionalizations varied according to race and ethnicity, age, and level of cognitive function. Programs that target older adults at greater risk may be an effective strategy for reducing new institutionalizations and fostering aging in place.     

Evaluation of the care pathway in the context of the dispensing of emicizumab (Hemlibra) in community and hospital pharmacies in France: A patient satisfaction survey

Introduction

Since June 2021 in France, patients with haemophilia A with anti-factor VIII inhibitors and patients with severe haemophilia A without anti-factor VIII inhibitors, and treated with emicizumab (Hemlibra), have to choose the dispensing circuit community or hospital pharmacy.

Aim

To evaluate satisfaction of patients whether they choose dispensation from a community pharmacy or retained dispensation from the hospital pharmacy, to understand the main motivation for choosing the community or the hospital pharmacy.

Methods

All patients living in France, regardless of age, were eligible to participate. Between September 13, 2022, and January 9, 2023, 175 respondents answered the satisfaction survey, including 123 in community pharmacy and 52 in hospital pharmacy.

Results

Eighteen months after availability in community pharmacies, treatment accessibility is improved for the benefit of the patient. The door-to-door travel times are significantly reduced to the community pharmacy with an average gain of 16.5 min saved from the place of residence. Patients are mostly satisfied with the new dispensing circuit especially concerning the overall satisfaction (p < .0001), the travel time (p < .0001) and the strong relationship with the pharmacist (p = .0022) compared to hospital pharmacy.

Conclusion

Innovation in care pathways is showing its full potential in improving access to medication, made possible by the implementation of a rigorous organization accompanied by training to enable healthcare professionals involved in primary care to provide appropriate management.     

Reducing the standard serving size of alcoholic beverages prompts reductions in alcohol consumption

Aims

To test whether reducing the standard serving size of alcoholic beverages would reduce voluntary alcohol consumption in a laboratory (study 1) and a real‐world drinking environment (study 2). Additionally, we modelled the potential public health benefit of reducing the standard serving size of on‐trade alcoholic beverages in the United Kingdom.

Design

Studies 1 and 2 were cluster‐randomized experiments. In the additional study, we used the Sheffield Alcohol Policy Model to estimate the number of deaths and hospital admissions that would be averted per year in the United Kingdom if a policy that reduces alcohol serving sizes in the on‐trade was introduced.

Setting

A semi‐naturalistic laboratory (study 1), a bar in Liverpool, UK (study 2).

Participants

Students and university staff members (study 1: n = 114, mean age = 24.8 years, 74.6% female), residents from local community (study 2: n = 164, mean age = 34.9 years, 57.3% female).

Interventions and comparators

In study 1, participants were assigned randomly to receive standard or reduced serving sizes (by 25%) of alcohol during a laboratory drinking session. In study 2, customers at a bar were served alcohol in either standard or reduced serving sizes (by 28.6–33.3%).

Measurements

Outcome measures were units of alcohol consumed within 1 hour (study 1) and up to 3 hours (study 2). Serving size condition was the primary predictor.

Findings

In study 1, a 25% reduction in alcohol serving size led to a 20.7–22.3% reduction in alcohol consumption. In study 2, a 28.6–33.3% reduction in alcohol serving size led to a 32.4–39.6% reduction in alcohol consumption. Modelling results indicated that decreasing the serving size of on‐trade alcoholic beverages by 25% could reduce the number of alcohol‐related hospital admissions and deaths per year in the United Kingdom by 4.4–10.5% and 5.6–13.2%, respectively.

Conclusions

Reducing the serving size of alcoholic beverages in the United Kingdom appears to lead to a reduction in alcohol consumption within a single drinking occasion.     

A survey of tobacco dependence treatment guidelines content in 61 countries

Aims

To assess tobacco dependence treatment guidelines content in accordance with Article 14 of the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) and its guidelines, and association between content and country income level.

Design

Cross‐sectional study.

Setting

On‐line survey from March to July 2016.

Participants

Contacts in 77 countries, including 68 FCTC Parties, six Signatories and three non‐Parties which had indicated having guidelines in previous surveys, or had not been surveyed before.

Measurements

A nine‐item questionnaire on guidelines content, key recommendations, writing and dissemination.

Findings

We received responses from contacts in 63 countries (82%); 61 had guidelines. The majority are for doctors (93%), primary care (92%) and nurses (75%). All recommend brief advice, 82% recording tobacco use in medical notes, 98% nicotine replacement therapy (NRT), 61% quitlines, 31% text messaging and 87% intensive specialist support, and 54% stress the importance of health‐care workers not using tobacco. Only 57% have a dissemination strategy, and 62% have not been updated for 5 or more years. Compared with high‐income countries, quitlines are less likely to be recommended in upper middle‐income countries guidelines [odds ratio (OR) = 0.15, 95% confidence interval (CI) = 0.04–0.61] and intensive specialist support in lower middle‐income countries guidelines (OR = 0.01, 95% CI = 0.00–0.20). Guidelines updating is associated positively with country income level (P = 0.027).

Conclusions

Although most tobacco dependence treatment guidelines in the 61 countries assessed in 2016 follow the World Health Organization's Framework Convention on Tobacco Control Article 14 recommendations and do not differ significantly by income level, improvements are needed in keeping guidelines up‐to‐date, applying good writing practices and developing a dissemination strategy.     

Hepatitis C Virus Clearance in Older Adults

Objectives

To determine whether older adults with the hepatitis C virus (HCV) achieve a sustained viral response (SVR) after treatment with direct‐acting antiviral therapy.

Participants

Individuals aged 80 and older with chronic HCV infection (N = 253; n = 213 with cirrhosis, n = 40 with advanced fibrosis).

Measurements

We investigated the efficacy, safety, and global clinical effect of treatment with different combinations of direct antiviral agents (DAAs). Participants with cirrhosis were staged according to Child‐Pugh‐Turcotte class, Model for End‐Stage Liver Disease score, and the D'Amico staging system. The type and number of comorbidities at baseline and hepatic and nonhepatic events during follow‐up were registered.

Results

Ninety‐five percent of participants with cirrhosis and 95% of those with advanced fibrosis attained SVR. The rate was independent of sex, HCV genotype, and treatment schedule. During a mean follow‐up of 14 ± 4 months (range 5–23 months), 34 events occurred in 27 participants: 10 hepatocellular carcinomas, 12 hepatic decompensations, 9 nonhepatic events, 3 deaths. Multivariate analysis of risk factors for experiencing adverse events during follow up showed that participants in D'Amico Stages 4 and 5, with a baseline serum albumin level of 3.5 mg/dL or less, and 3 or more comorbidities were the most at risk.

Conclusion

In a real‐world setting, DAAs are safe and effective in older adults with HCV‐related advanced fibrosis or cirrhosis. Individuals with preserved albumin synthesis and fewer than 3 comorbidities at baseline have the most to gain from long‐term DAA therapy.     

Left atrial dyssynchrony in veteran endurance athletes with and without paroxysmal atrial fibrillation

Background

Prolonged endurance exercise increase the risk of atrial fibrillation (AF) in men. Functional parameters may help separate physiological from pathological atrial remodeling in athletes. LA mechanical dispersion (LA MD) is associated with AF in the general population, but the associations between prolonged exercise, LA MD and AF are not known.

Purpose

To describe LA MD in veteran athletes with and without paroxysmal AF (pAF) and to investigate LA MD's ability to identify veteran athletes with pAF.

Methods

Two hundred and ninety-three men, skiers with (n = 57) and without (n = 87) pAF, and controls with (n = 61) and without pAF (n = 88) underwent an echocardiographic exam in sinus rhythm. LA reservoir strain (LASr) was measured, and LA MD defined as the standard deviation of time-to-peak strain (SD-TPS).

Results

Skiers (mean age 70.7 ± 6.7 years) reported an average of 40–50 years of endurance exercise. LA volumes were associated with pAF and athletic status (p < .001). SD-TPS was associated with pAF (p < .001) but not athletic status (p = .173). We found no significant trend between years of exercise and SD-TPS in individuals without AF (p = .893). SD-TPS did not add incremental value in identifying athletes with pAF in addition to clinical markers, QRS width, LA volume, and LASr (p = .056).

Conclusion

LA MD was associated with pAF regardless of athletic status but not related to years of endurance exercise, suggesting LA MD could be a promising marker of pathological atrial remodeling in athletes. However, we found no incremental value of LA MD identifying athletes with pAF when LASr was included in the model.     

Rapid changes in serum cytokines and chemokines in response to inactivated influenza vaccination

Background

The timing of host cytokine responses to influenza vaccination is poorly understood.

Objectives

We examined serum cytokine kinetics following inactivated trivalent influenza vaccine (TIV) to better understand potential relationships between markers of inflammation and TIV‐related side effects.

Patients/Methods

Twenty healthy adult subjects received TIV. Cytokines/chemokines were assessed in intervals from 3 hours to 14 days. Antibody titers were measured at baseline and Day 14.

Results

Serum cytokine responses to TIV were evident as early as 3 hours post‐immunization. Compared to baseline, IFN‐γ and IP‐10 were significantly elevated 7 hours after TIV administration. Both remained elevated and peaked between 16 and 24 hours before returning to baseline by 44 hours post‐vaccination. Although IL‐8 levels were variable between subjects during the first 24 hours after TIV, by 44 hours, IL‐8 was significantly lower compared to baseline. Interestingly, IL‐8 levels remained significantly lower for up to 2 weeks after receiving TIV. Fifteen of 20 subjects reported mild adverse events. The one subject who reported moderate myalgias and injection site pain after vaccination displayed a distinctive, early cytokine response profile which included IL‐6, IL‐2, IL‐8, IP‐10, MCP‐1, TNF‐α, TARC, and MCP‐4.

Conclusions

Serum cytokines changed rapidly following TIV and generally peaked at 24 hours. Trivalent influenza vaccine‐induced reductions in IL‐8 occurred later (44 hours) and were sustained for 2 weeks. An outlier response coincided with the only moderate side effects to the vaccine. These data suggest that early cytokine/chemokine responses may provide additional insight into the pathogenesis of adverse events and immune reactivity to vaccination.     

Understanding the practice patterns of nephrology nurse practitioners in Australia

Background

Nurse practitioners (NP) have an expanded scope of practice beyond that of a registered nurse. In kidney care, nephrology NP can manage patients at various points along the chronic kidney disease (CKD) trajectory.

Objectives

To profile the characteristics, service patterns, and domains of practice of nephrology NP in Australia.

Design

A cross-sectional online secure survey.

Participants

Nephrology NP (NP students) who were members of the Renal Society of Australasia and working in Australia (n = 73).

Measurements

Data collected were demographic and practice characteristics, and domains of practice (using the modified Strong Model of Advanced Practice). The survey also sought qualitative perspectives of the enablers and barriers to sustainability nurse practitioner healthcare delivery services.

Results

Nephrology NP (n = 45) primarily worked in adult services, managing those receiving haemodialysis, peritoneal dialysis, or patients with earlier grades of CKD. Providing direct comprehensive care was the dominant domain of advanced practice although administrative activities took up considerable time each week. Support from nurse leaders and medical colleagues was identified as key enablers for sustainability of these services whereas succession planning, and workload were the main barriers.

Conclusions

This study found a highly qualified, experienced but older nephrology nurse practitioner workforce who provide an additional model of health service delivery which can meet the growing CKD burden. Internationally, this level of nurse provides an opportunity for a career pathway to maintain nurses in direct clinical roles and to expand the nephrology nursing workforce.     

Factors associated with the efficacy of smoking cessation treatments and predictors of smoking abstinence in EAGLES

Aims

To assess (1) how far the efficacies of front‐line smoking cessation pharmacotherapies vary as a function of smoker characteristics and (2) associations between these characteristics and success of smoking cessation attempts.

Design

Prospective correlational study in the context of a double‐blind randomized trial. The outcome was regressed individually onto each covariate after adjusting for treatment, and then a forward stepwise model constructed. Treatment moderator effects of covariates were tested by treatment × covariate interactions.

Setting

Health service facilities in multiple countries.

Participants

Data came from 8120 smokers willing to make a quit attempt, randomized to varenicline, bupropion, nicotine replacement therapy (NRT) or placebo in Evaluating Adverse Events in a Global Smoking Cessation Study (EAGLES) between 30 November 2011 and 13 January 2015.

Measurements

Smoker characteristics measured at baseline were country, psychiatric history, sex, age, body mass index (BMI), ethnic group, life‐time suicidal ideation/behaviour, anxiety, depression, aggression, psychotropic medication, history of alcohol/substance use disorder, age of starting smoking, cigarette dependence [Fagerström Test for Cigarette Dependence (FTCD)] and prior use of study medicines. Outcome was biochemically confirmed continuous abstinence at weeks 9–24 from start of treatment.

Findings

No statistically significant treatment × covariate interactions were found. Odds of success were associated independently positively with age [odds ratio (OR) = 1.01; 95% confidence interval (CI) = 1.00, 1.01], BMI (1.01; 95% CI = 1.00, 1.02) and age of starting smoking (1.03; 95% CI = 1.02, 1.04). Odds were associated independently negatively with US (versus non‐US) study site (0.53; 95% CI = 0.46, 0.61), black (versus white) ethnic group (0.57; 95% CI = 0.45, 0.72), mood disorder (0.85; 95% CI = 0.73, 0.99), anxiety disorder (0.71; 95% CI = 0.55, 0.90) and psychotic disorder (0.73; 95% CI = 0.50, 1.07), taking psychotropic medication (0.81; 95% CI = 0.68, 0.95), FTCD (0.89; 95% CI = 0.87, 0.92) and previous use of NRT (0.78; 95% CI = 0.67, 0.91).

Conclusions

While a range of smoker characteristics—including psychiatric history, cigarette dependence and prior use of nicotine replacement therapy (NRT)—are associated with lower cessation rates, they do not substantially influence the efficacy of varenicline, bupropion or NRT.     

Human bocavirus and human metapneumovirus in hospitalized children with lower respiratory tract illness in Changsha,China

Background

Lower respiratory tract illness is a major cause of morbidity and mortality in children worldwide, however, information about the epidemiological and clinical characteristics of LRTIs caused by HMPV and HBoV in China is limited.

Objectives

Human bocavirus (HBoV) and human metapneumovirus (HMPV) are two important viruses for children with lower respiratory tract infections (LRTI). We aimed to assay the correlation between viral load and clinical characteristics of HBoV and HMPV with LRTI in Changsha, China.

Methods

Nasopharyngeal aspirates (NPAs) from children with LRTI were collected. Real‐time PCR was used to screen HBoV and HMPV. Analyses were performed using SPSS 16.0 software.

Results

Pneumonia was the most frequent diagnosis. There was no significant difference between HBoV‐ and HMPV‐positive patients in age (P = .506) or hospitalization duration (P = .280); 24.1% and 18.2% were positive for HBoV and HMPV. HBoV infections peaked in summer (32.2%), and HMPV infections peaked in winter (28.9%). The HBoV‐positive patients had a shorter hospitalization duration than the HBoV‐negative patients (P = .021), and the HMPV‐positive patients had a higher prevalence of fever than the HMPV‐negative patients (P = .002). The HBoV viral load was significantly higher among patients aged <1 year (P = .006). The mean HBoV and HMPV viral loads were not significantly different between patients with single infections and coinfections. Patients infected with HBoV only were older than those coinfected with HBoV and other respiratory viruses (P = .005). No significant difference was found in the clinical characteristics of patients infected with HMPV only and those coinfected with HMPV and other respiratory viruses.

Conclusion

Pneumonia was the most frequent diagnosis caused by HBoV and HMPV. Neither HBoV nor HMPV viral load was correlated with disease severity.     

The prevalence and risk factors for acute respiratory infections in children aged 0‐59 months in rural Malawi: A cross‐sectional study

Background

Acute Respiratory Infections (ARI) are a leading cause of childhood mortality and morbidity. Malawi has high childhood mortality but limited data on the prevalence of disease in the community.

Methods

A cross‐sectional study of children aged 0‐59 months. Health passports were examined for ARI diagnoses in the preceding 12 months. Children were physically examined for malnutrition or current ARI.

Results

828 children participated. The annual prevalence of ARI was 32.6% (95% CI 29.3‐36.0%). Having a sibling with ARI (OR 1.44, P = .01), increasing household density (OR 2.17, P = .02) and acute malnutrition (OR 1.69, P = .01) were predictors of infection in the last year. The point prevalence of ARI was 8.3% (95% CI 6.8‐10.4%). Risk factors for current ARI were acute‐on‐chronic malnutrition (OR 3.06, P = .02), increasing household density (OR1.19, P = .05) and having a sibling with ARI (OR 2.30, P = .02).

Conclusion

This study provides novel data on the high prevalence of ARI in Malawi. This baseline data can be used in the monitoring and planning of future interventions in this population.     

‘Mindful eating’ for reducing emotional eating in patients with overweight or obesity in primary care settings: A randomized controlled trial

Objective

The primary aim of this study was to analyse the efficacy of a ‘mindful eating’ programme for reducing emotional eating in patients with overweight or obesity.

Method

A cluster randomized controlled trial (reg. NCT03927534) was conducted with 76 participants with overweight/obesity who were assigned to ‘mindful eating’ (7 weeks) + treatment as usual (TAU), or to TAU alone. They were assessed at baseline, posttreatment and 12-month follow-up. The main outcome was ‘emotional eating’ (Dutch Eating Behaviour Questionnaire, DEBQ); other eating behaviours were also assessed along with psychological and physiological variables.

Results

‘Mindful eating’ + TAU reduced emotional eating both at posttreatment (B = −0.27; p = 0.006; d = 0.35) and follow-up (B = −0.53; p < 0.001; d = 0.69) compared to the control group (TAU alone). ‘External eating’ (DEBQ) was also significantly improved by the intervention at both timepoints. Significant effects at follow-up were observed for some secondary outcomes related to bulimic behaviours, mindful eating, mindfulness, and self-compassion. Weight and other physiological parameters were not significantly affected by ‘mindful eating’ + TAU.

Conclusions

These findings support the efficacy of the ‘mindful eating’ + TAU programme for reducing emotional and external eating, along with some other secondary measures, but no significant changes in weight reduction were observed.     

Ribavirin dose management in HCV patients receiving ombitasvir/paritaprevir/ritonavir and dasabuvir with ribavirin

Background & Aims

Some individuals with hepatitis C virus infection treated with direct‐acting antivirals require ribavirin to maximize sustained virological response rates. We describe the clinical management of ribavirin dosing in hepatitis C virus‐infected patients receiving ombitasvir/paritaprevir/ritonavir and dasabuvir with ribavirin.

Methods

We performed a post hoc analysis of patients receiving ombitasvir/paritaprevir/ritonavir and dasabuvir with ribavirin for 12 or 24 weeks in six phase 3 trials. Multivariate stepwise logistic regression models assessed predictors associated with ribavirin dose adjustments and with developing anaemia.

Results

Of 1548 patients, 100 (6.5%) modified ribavirin dose due to haemoglobin declines, of which 99% achieved sustained virological response at 12 weeks post‐treatment. Median time to first ribavirin dose reduction was 37 days. Low baseline haemoglobin was significantly associated with an increased risk of requiring ribavirin dose modification (odds ratio: 0.618 [0.518, 0.738]; P < .001) and developing anaemia (odds ratio: 0.379 [0.243, 0.593]; P < .001).

Conclusions

Ribavirin dose reductions were infrequent, occurred early in treatment, and did not impact sustained virological response at 12 weeks post‐treatment. Patients with low baseline haemoglobin should be monitored for on‐treatment anaemia.
