Opioids Diminish the Placebo Antidepressant Response: A Post Hoc Analysis of a Randomized Controlled Ketamine Trial.

Background: The endogenous opioid system is thought to play a role in the placebo antidepressant response. A recent trial comparing the rapid antidepressant effects of ketamine versus placebo in surgical patients, some of whom were on chronic opioid therapy, revealed a substantial placebo effect. This finding provided an opportunity to test the hypothesis that opioid agonist exposure interacts with placebo antidepressant responses.

Prevalence and characteristics of preoperative patients with depression.

Background: Within the perioperative period, depression-related diagnoses are associated with postoperative complications. We developed a perioperative depression screening programme to assess disease prevalence and feasibility for intervention.

Methods: Adult patients in multiple surgical departments at a single academic centre were screened for depression via the electronic health record patient portal or preoperative anaesthesia clinic before surgery, using the Patient Health Questionnaire (PHQ)-2 and -8.

Effects of increasing omega-3 fatty acids on growth performance, immune response, and mortality in nursery pigs.

Three experiments evaluated omega-3 fatty acids, provided by O3 trial feed, on nursery pig growth performance, mortality, and response to an LPS immune challenge or natural Porcine reproductive and respiratory virus (PRRSV) outbreak. In experiment 1, 350 pigs (241 × 600, DNA; initially 5.8 kg) were used.

Randomized trial of ketamine masked by surgical anesthesia in patients with depression.

Ketamine may have antidepressant properties, but its acute psychoactive effects complicate successful masking in placebo-controlled trials. We present a single-center, parallel-arm, triple-masked, randomized, placebo-controlled trial assessing the antidepressant efficacy of intravenous ketamine masked by surgical anesthesia (ClinicalTrials.gov, NCT03861988).

A cross-stakeholder approach to improving out-of-hospital cardiac arrest survival.

Background: Out-of-hospital cardiac arrest (OHCA) affects over 300,000 individuals per year in the United States with poor survival rates overall. A remarkable 5-fold difference in survival-to-hospital discharge rates exist across United States communities.

Methods: We conducted a study using qualitative research methods comparing the system of care across sites in Michigan communities with varying OHCA survival outcomes, as measured by return to spontaneous circulation with pulse upon emergency department arrival.

Development of equations to predict the influence of floor space on average daily gain, average daily feed intake and gain : feed ratio of finishing pigs.

Floor space allowance for pigs has substantial effects on pig growth and welfare. Data from 30 papers examining the influence of floor space allowance on the growth of finishing pigs was used in a meta-analysis to develop alternative prediction equations for average daily gain (ADG), average daily feed intake (ADFI) and gain : feed ratio (G : F). Treatment means were compiled in a database that contained 30 papers for ADG and 28 papers for ADFI and G : F.

Evaluating the impact of maternal vitamin D supplementation on sow performance: II. Subsequent growth performance and carcass characteristics of growing pigs.

A of subsample of 448 growing pigs (PIC 327 × 1050) weaned from 52 sows fed varying dietary vitamin D regimens were used in a split-plot design to determine the effects of maternal and nursery dietary vitamin D on growth performance. Sows were previously administered diets containing vitamin D as vitamin D (800, 2,000, or 9,600 IU/kg) or as 25(OH)D (50 µg [or 2,000 IU vitamin D equivalent]/kg from HyD; DSM Nutritional Products, Parsippany, NJ). Once weaned, pigs were allotted to pens on the basis of previous maternal vitamin D treatment, and then pens were randomly assigned to 1 of 2 nursery vitamin D dietary regimens (2,000 IU of vitamin D/kg or 50 µg 25(OH)D/kg).

Evaluating the impact of maternal vitamin D supplementation: I. Sow performance, serum vitamin metabolites, and neonatal muscle characteristics.

In Exp. 1, 56 gestating sows (PIC 1050; 35 d postinsemination) were used in a 30-d trial to determine serum 25(OH)D response to increasing concentrations of dietary vitamin D. Sows were randomly allotted to 1 of 7 dietary D treatments (200, 800, 1,600, 3,200, 6,400, 12,800, or 25,600 IU of added D per kilogram of complete diet) with 8 sows per treatment.

Evaluating the removal of pigs from a group and subsequent floor space allowance on the growth performance of heavy-weight finishing pigs.

A total of 1,092 finishing pigs (initially 36.3 kg) were used in a 117-d study to evaluate the impact of initial floor space allowance and removal strategy on the growth of pigs up to 140 kg BW. There were 4 experimental treatments with 14 pens per treatment.

[New oral anticoagulants for prophylaxis of stroke. Results of an expert conference on practical use in geriatric patients].

Geriatric patients with non-valvular atrial fibrillation (AF) are increasingly being treated with novel oral anticoagulants (NOAC) to prevent ischemic stroke. This article highlights the outcome of an expert meeting on the practical use of NOAC in elderly patients. An interdisciplinary group of experts discussed the current situation of stroke prevention in geriatric patients and its practical management in daily clinical practice.

[Optimal stroke prevention in the geriatric patient with atrial fibrillation: position paper of an interdisciplinary expert panel].

Background: The optimal approach to stroke prevention in geriatric patients with atrial fibrillation (AF) has not been adequately clarified. Despite their high risk of stroke and clear indication for anticoagulation according to established risk scores, in practice geriatric AF patients often are withheld treatment because of comorbidities and comedications, concerns about low treatment adherence or fear of bleeding events, in particular due to falls.

Method: The present position paper summarises the outcomes of an expert panel discussion held by hospital-based and office-based physicians with ample experience in the treatment of geriatric patients.

Improving the health care of geriatric patients: management of urinary incontinence: a position paper.

A multidisciplinary German expert group met in 2012 to discuss the current status and prospects of health care of geriatric patients with urinary incontinence in Germany. The purpose of this position paper is to raise awareness among health care providers for the challenges associated with adequate management of urinary incontinence in frail elderly. The experts agree that a multidisciplinary collaboration is essential for the successful treatment of urinary incontinence symptoms which are often associated with loss of autonomy and social isolation.

Impact of pharyngeal closure technique on fistula after salvage laryngectomy.

Importance: No consensus exists as to the best technique, or techniques, to optimize wound healing, decrease pharyngocutaneous fistula formation, and shorten both hospital length of stay and time to initiation of oral intake after salvage laryngectomy. We sought to combine the recent experience of multiple high-volume institutions, with different reconstructive preferences, in the management of pharyngeal closure technique for post-radiation therapy salvage total laryngectomy in an effort to bring clarity to this clinical challenge.

Objective: To determine if the use of vascularized flaps in either an onlay or interposed fashion reduces the incidence or duration of pharyngocutaneous fistula after salvage laryngectomy compared with simple primary closure of the pharynx.

Identical but different: mechanism of cancer development and response to treatment for human papillomavirus-related and non-related squamous cell cancer of the head and neck.

Head and neck squamous cell carcinoma (HNSCC) continues to be a significant cause of cancer worldwide. Tobacco and alcohol use are the most common risk factors for HNSCC. Over the past five years, research has identified the human papillomavirus (HPV) as a factor in the development of approximately 25 percent of HNSCC.

Effect of a family-based intervention on electronic media use and body composition among boys aged 8--11 years: a pilot study.

This study measured the effect of a 20-week, family-centered electronic media intervention on electronic media use, body composition (dual-energy X-ray absorptiometry; DXA), physical activity and dietary behaviors in boys. Twenty-two boys were assigned and 21 were analyzed in an experimental or control group. Boys in the experimental group set electronic media use goals and used TV Allowance device and ENUFF software to reduce electronic media use.

Women Bound to Be Active: a pilot study to explore the feasibility of an intervention to increase physical activity and self-worth in women.

Increasing physical activity (PA) has become a national health objective due to its associated health benefits, but low participation rates. Therefore, the purpose of this study was to determine the feasibility of an 8-month (September 2006-April 2007) PA book club (Women Bound to Be Active-WBA) in increasing PA and self-worth (SW) among women. Fifty-six adult women participated in an 8-month intervention consisting of weekly meetings designed to improve PA knowledge, awareness, confidence, and SW.

Explaining long-term exercise adherence in women who complete a structured exercise program.

The purpose of this study was to qualitatively examine factors related to physical activity adherence to understand why women continue to participate in long-term exercise after completing a structured exercise program. Data were collected from focus groups, interviews, and e-mails, and analysis used grounded theory. The central category related to physical activity adherence was self-worth.

Pedometer-assessed physical activity in young adolescents.
