To maximize the benefits of test and treat strategies that utilize community-based HIV testing, clients who test positive must link to care in a timely manner. However, linkage rates across the HIV treatment cascade are typically low and little is known about what might facilitate or hinder care-seeking behavior. This qualitative study was conducted within a home-based HIV counseling and testing (HBHCT) intervention in South Africa. In-depth interviews were conducted with 30 HBHCT clients who tested HIV positive to explore what influenced their care-seeking behavior...

Previous research has extensively evaluated the impact of delay on the value of positive reinforcers, but the study of its impact on the value of aversive consequences is scarce. The present study employed a modification of Evenden and Ryan's procedure (1996, Psychopharmacology, 128(2), 161-170) to obtain data on temporal discounting of an aversive consequence, with rats as experimental subjects. In the first phase of the procedure, rats chose between one-pellet and four-pellet alternatives; when subjects developed preference for the larger-amount alternative, a shock was added to it, resulting in a loss of preference...

REVIEW
Christian P Müller
Drug addiction is a psychiatric disorder based on a dysfunction of the brain. It frequently develops from a controlled drug consumption and drug instrumentalization (DI). Thereby, DI is the use of a drug to improve specific non-drug related behaviors, beyond the drug's direct positive or negative reinforcing effects. Currently available pharmacotherapies for drug addiction show low effect size and rather limited long-term efficacy, which suggests that current theories on addiction are still insufficient in how they capture the phenomenon and how they allow predictions for highly efficient treatments...

The title compound, C30H44N2O4 [systematic name: 2,6-di-decyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-one], consists of a central pyromellitic di-imide moiety with terminal decyl groups at the N-atom positions. The centre of the mol-ecule lies on a crystallographic inversion centre so the asymmetric unit contains one half-mol-ecule. The mol-ecule exhibits a rod-shaped conformation, like other similar compounds of this type, the distance between the ends of terminal decyl groups being 32.45 Å. The packing is dominated by a lamellar arrangement of the mol-ecules, which is reinforced by C-H⋯O hydrogen bonds and C-O⋯π inter-actions, forming a classic herringbone structure...

BACKGROUND: Subspecialty consultation in inpatient care is increasing. Teaching by subspecialty fellows in a consultation setting may be an important source of work-based learning for students and residents. However, teaching and evaluation of learners in this context may be challenging due to personal and systems-based barriers. OBJECTIVE: We developed and evaluated a framework designed to overcome barriers to teaching and to improve fellow teaching skills during inpatient consultation...

BACKGROUND: National organizations recommend pediatricians screen for food insecurity (FI). Although there has been growing research in urban practices, little research has addressed FI screening in suburban practices. We evaluated the feasibility, acceptability, and impact of screening in suburban practices. METHODS: We conducted a mixed methods study that implemented FI screening in 6 suburban pediatric primary care practices. We included all children presenting for either a 2-, 15-, or 36-month well-child visit (N = 5645)...

BACKGROUND: Managing children is a challenge that many dentists face. Many non-pharmacological techniques have been developed to manage anxiety and behavioural problems in children, such us: 'tell, show & do', positive reinforcement, modelling and hypnosis. The use of hypnosis is generally an overlooked area, hence the need for this review. OBJECTIVES: This systematic review attempted to answer the question: What is the effectiveness of hypnosis (with or without sedation) for behaviour management of children who are receiving dental care in order to allow successful completion of treatment?Null hypothesis: Hypnosis has no effect on the outcome of dental treatment of children...

Images of sexually active women beyond the age of 50 are lacking in popular culture and in particular on television. Dominant sexual scripts depict older women as generally asexual. The television program Hot in Cleveland features unpartnered midlife and older women as main characters. In this article, based on analysis of four seasons of Hot in Cleveland, we look closely at portrayals of sexual activity to see whether they underscore dominant sexual scripts mocking older women's sexual interest, position aging as sexual decline, or reinforce the narrative of "successful" aging/aging as progress...

Bullying remains a pervasive problem in healthcare, and evidence suggests systems in place are not utilised due to perceptions of ineffectiveness and inequity. This study examines bystander responses to bullying and factors that influence decisions to intervene. We explore relationships between bystanders' perceptions of psychological safety across three levels (organisation, supervisor and colleague) and reactions to witnessing bullying. We suggest psychological safety would be positively associated with the decision to intervene...

Vaccine hesitancy or lack of confidence in vaccines is considered a threat to the success of vaccination programs. The rise and spread of measles outbreaks in southern Africa in 2009-2010 were linked to objections among Apostolic Church members, estimated at about 3.5 million in Zimbabwe as of 2014. To inform planning of interventions for a measles-rubella vaccination campaign, we conducted an assessment of the factors contributing to vaccine hesitancy using data from various stakeholders. Among nine districts in three regions of Zimbabwe, we collected data on religious attitudes toward, and perceptions of, vaccines through focus group discussions with health workers serving Apostolic communities and members of the National Expanded Programme on Immunization; semi-structured interviews with religious leaders; and open-ended questions in structured interviews with Apostolic parents/caregivers...

BACKGROUND: Various factors contribute to instability of total hip arthroplasty (THA), with implant orientation being a major contributor. We performed a case-control study with computed tomography (CT) data to determine whether 1) orientation contributes to THA instability and 2) a safer target zone for stability than Lewinnek's classic safe zone can be defined. MATERIAL AND METHODS: We included prospectively 363 cases of THA dislocation that occurred during the calendar 2013 year in 24 participating hospitals...

BACKGROUND: "Pimping" is an informal teaching technique that is widely used in medical education. Pimping is characterized by questioning the learner with the intent of reinforcing clinical hierarchy. To date, there are no studies of the use of pimping in pharmacy education. OBJECTIVES: To describe the use of pimping as a teaching method in pharmacy education and to compare student and faculty perceptions of this technique. METHODS: Faculty and fourth-year PharmD (P4) students from 2 colleges of pharmacy were invited to participate in a survey about experiences and perceptions of pimping...

Nursing pharmacology can pose a challenge to nursing students as they learn about different disease processes and interventions. Having students engage in their own learning process aids in the retention of information and gives positive reinforcement for exams. Using YouTube as a part of student group presentations helps students engage in the learning process and learn difficult pharmacological concepts in an alternative classroom setting.

This study tested a model linking sensitivity to punishment (SP) and reward (SR) to marijuana use and problems via affect lability and poor control. A 6-month prospective design was used in a sample of 2,270 young-adults (64% female). The hypothesized SP × SR interaction did not predict affect lability or poor control, but did predict use likelihood at baseline. At low levels of SR, SP was associated with an increased likelihood of abstaining, which was attenuated as SR increased. SP and SR displayed positive main effects on both affect lability and poor control...

BACKGROUND: Negative reinforcement theories of drug addiction posit that addicts use drugs to alleviate negative mood states. In a preclinical model developed in our laboratory, rats exhibit negative affect to a normally rewarding taste cue when it predicts impending but delayed cocaine. The emergence of this state is accompanied by a reduction in dopamine concentration in the rostral nucleus accumbens shell. However, the rostral and caudal regions of the shell have been implicated in promoting opposing appetitive and aversive states, respectively...

BACKGROUND: Commonly, intramedullary nails are made of nondegradable materials, and hence they need to be removed once the bone fracture is healed. We propose a novel composite material consisting of poly-L-lactide matrix modified with carbon and alginate fibers to be used for biodegradable intramedullary fixation. The aim of this study was to make in vitro and in vivo biocompatibility assessments. METHODS: In the in vitro conditions, biocompatibility of biomaterials was compared using normal human osteoblasts...

Neurofibromatosis Type 1 (NF1) is a neurocutaneous disorder that can have associated spinal abnormalities related to both bone and dural dysplasia. Thoracic meningoceles are one spine anomaly associated with NF1, although they are a fairly uncommon pathology. Surgical techniques to treat these meningoceles, usually undertaken only when the patient is symptomatic, are targeted at decreasing the size of the protrusion and improving lung capacity. Surgical interventions discussed in the literature include shunting the pseudomeningocele, primary repair with laminectomy, thoracoscopic plication, and reinforcement of the closure with cement, muscle, or fascia...
