Positive reinforcement by general practitioners is associated with greater physical activity in adults with type 2 diabetes

© Author(s) (or their employer(s)) 2019. Objective In a sample of adults with type 2 diabetes mellitus (T2DM), the aim of this study was to examine whether self-reported physical activity level is associated with recall of specific physical activity-related interactions used by general practitioners (GP). Research design and methods Adults with T2DM completed an online survey reporting physical activity behaviors and recall of 14 GP-patient interactions about physical activity, mapped onto discrete behavior change techniques (BCT). Stepped logistical regression examined associations between recommended physical activity (≥600 MET-min/week) and GP-patient interactions, controlling for body mass index, diabetes-related comorbidities, depressive symptoms and self-efficacy. Results In total, 381 respondents (55% men, mean±SD age: 62±10 years and T2DM duration 8±8 years) provided complete data. Most (73%) reported receiving 'general advice', while interactions related to goal setting, monitoring, and relapse prevention were least commonly reported (all <20%). Self-reported achievement of the recommended physical activity level was significantly associated with recall of GP interactions involving praise for 'efforts to be active' (OR 2.1; 95% CI 1.24 to 3.53), 'lost weight' (OR 1.81; 95% CI 1.05 to 3.12) or lowering 'glucose levels as a result of being active' (OR 1.75; 95% CI 1.03 to 2.96). Conclusions Findings suggest GPS can be somewhat effective in promoting physical activity with simple, positive, reinforcing messages/interactions. Future research to develop and evaluate very brief primary care BCT-based physical activity interventions is needed

Lesson Plans for Teaching Economics with The Big Bang Theory

Using examples in the classroom from current and past television shows and movies is becoming increasingly common. Being able to relate ideas back to a popular clip or episode allows the instructor to reach students in ways the traditional lecture cannot. Building on the work of Tierney, Mateer, Smith, Wooten, and Geerling (2016), this paper introduces five lesson plans tied to clips from The Big Bang Theory that can be used in high school (9-12) economics courses

A methodology to systematically analyze the hospital discharge of terminally ill patients

To provide an appropriate method to systematically analyze the hospital discharge of terminally ill patients especially the cooperation between hospital and community nurses and the quality of the discharge handovers. To evaluate the hospital discharge process of terminally ill patients in an academic hospital in the Netherlands using the proposed method. Data were collected from a prospective cohort of all terminally ill patients discharged from the University Medical Center Groningen, the Netherlands, between June and November 2014. The hospital discharges were assessed using 2 questionnaires: an inventory questionnaire, to determine the required care, and an evaluation questionnaire, to evaluate the care actually organized and the discharge handovers. The inventory questionnaire was completed prior to discharge and the evaluation questionnaire between 3 to 7 days after discharge. Around 130 consecutive patients were included. The discharge took place on the desired date in 86% of cases and the average overall discharge grade on a 10-point scale was 7.4 (range: 3-9.5). In 23% of cases discrepancies between required and provided care were identified and medication queries existed in 29%. This study provides a methodology to analyze the hospital discharge procedure of terminally ill patients that can be utlized in any hospital. Structured analysis of the discharge process is valuable and identifies where improvements can be made. Within the study cohort the home care could be arranged at short notice and was considered sufficient. However, in a significant proportion of patients a discrepancy between required and arranged care and queries about medication were identified

Injection of recombinant tumor necrosis factor directly into liver metastases: an experimental and clinical approach

__Abstract__ Systemic treatment with tumor necrosis factor (TNF) is associated with side-effects, limiting its clinical use in the treatment of malignancies. To investigate the feasibility of other routes of administration experimental and clinical studies were started to establish the toxicity and antitumor activity of TNF after intratumoral (i.t.) injection. In a rat model for colon adenocarcinoma, tumor fragments, implanted subcutaneously or under the hepatic capsule, were treated with TNF injected i.v. or i.t. A dosage of 40 μg/kg was lethal when given i.v., but not i.t. Injection of TNF (40 μg/kg) directly into the tumor resulted in inhibition of tumor growth in the subcutaneous as well as subhepatic tumor model. A phase I study was started in patient

Prospective, randomized, double-blind trial to investigate the efficacy and safety of corneal cross-linking to halt the progression of keratoconus

Background: Corneal cross-linking is widely used to treat keratoconus. However, to date, only limited data from randomized trials support its efficacy. Methods: The efficacy and safety of corneal cross-linking for halting progression of keratoconus were investigated in a prospective, randomized, blinded, placebo controlled, multicentre trial. Twenty-nine keratoconus patients were randomized in three trial centres. The mean age at inclusion was 28 years. Longitudinal changes in corneal refraction were assessed by linear regression. The best corrected visual acuity, surface defects and corneal inflammation were also assessed. These data were analysed with a multifactorial linear regression model. Results: A total of 15 eyes were randomized to the treatment and 14 to the control group. Follow-up averaged 1098 days. Corneal refractive power decreased on average (+/-standard deviation) by 0.35 +/- 0.58 dioptres/year in the treatment group. The controls showed an increase of 0.11 +/- 0.61 dioptres/year. This difference was statistically significant (p = 0.02). Conclusions: Our data suggest that corneal cross-linking is an effective treatment for some patients to halt the progression of keratoconus. However, some of the treated patients still progressed, whereas some untreated controls improved. Therefore, further investigations are necessary to decide which patients require treatment and which do not

Effects of Decreased Loading on the Mandible

Background Bone mass and mineralization are largely influenced by loading. The purpose of this study was to evaluate the reaction of the entire mandibular bone in response to decreased load during growth. It is hypothesized that decreased muscular loading will lead to bone changes as seen during disuse, i.e. loss of bone mass. Methods and Findings Ten 21-day-old Wistar strain male rats were divided into two groups (each n=5) and fed on either a hard- or soft-diet for 11 weeks. Micro-computed tomography was used for the investigation of bone mineralization, bone volume, bone volume fraction (BV/TV) and morphological analysis. Mandibular mineralization patterns were very consistent, showing a lower degree of mineralization in the ramus than in the corpus. In the soft-diet group, mineralization below the molars was significantly increased (p<0.05) compared to the hard diet group. Also, bone volume and BV/TV of the condyle and the masseter attachment were decreased in the soft-diet group (p<0.05). Morphological analysis showed inhibited growth of the ramus in the soft-diet group (p<0.05). Conclusion Decreased loading by a soft diet causes significant changes in the mandible. However, these changes are very region-specific, probably depending on the alterations in the local loading regime. The results suggest that muscle activity during growth is very important for bone quality and morphology

Nurse-Midwives’ Knowledge and Promotion of Lactational Amenorrhea and Other Natural Family-Planning Methods for Child Spacing

The purpose of this study was to describe and assess certified nurse-midwives’ (CNMs) knowledge and promotion of two modalities for child spacing, natural family-planning (NFP) and the lactational amenorrhea method (LAM). One thousand two hundred CNMs were randomly selected from a national membership list and mailed a 24-item questionnaire on NFP and LAM. Of the 514 respondents (42.8% return rate), 450 (87.5%) were currently practicing as CNMs. Respondents had an average age of 46 years, with an average of 10 years of practice. CNMs ranked NFP as the ninth most used and the eighth most effective family-planning method in their practice, with an average perceived method-effectiveness of 88% and use-effectiveness of 70%. Although most respondents felt somewhat prepared during their education program to provide NFP, only 22% would offer NFP as a family-planning option for child spacing

Abca1 deficiency protects the heart against myocardial infarction-induced injury

Background and aims We explored the role of ATP-binding cassette transporter A1 (Abca1), in post-myocardial infarction (MI) cardiac injury. Methods In Abca1–/– mice, wild type (WT) mice, and WT mice transplanted with Abca1–/– or WT bone marrow, an MI was induced in vivo. Furthermore, an ex vivo MI was induced in isolated Abca1–/– and WT hearts. Results Twenty-four hours and two weeks after in vivo MI induction, MI size was reduced in Abca1–/– (−58%, p = 0.007; −59%, p = 0.03) compared to WT. Ex vivo MI induction showed no effect of Abca1–/– on infarct size. Interestingly, two weeks after MI, Abca1–/– mice showed higher circulating levels of B-cells (+3.0 fold, p = 0.02) and T-cells (+4.2 fold, p = 0.002) compared to WT. Bone marrow-specific Abca1–/– tended to reduce infarct size (−43%, p = 0.12), suggesting a detrimental role for hematopoietic Abca1 after MI. Conclusions Although Abca1 has a protective role in atherosclerosis, it exerts detrimental effects on cardiac function after MI. Keywords * Abca1 deficiency; * Myocardial infarction; * Immune cells; * Mic

Hematopoietic upstream stimulating factor 1 deficiency is associated with increased atherosclerosis susceptibility in LDL receptor knockout mice

Total body upstream stimulatory factor 1 (USF1) deficiency in mice is associated with brown adipose tissue activation and a marked protection against the development of obesity and atherosclerotic lesions. Functional expression of USF1 has also been detected in monocytes and monocyte-derived macrophages. In the current study we therefore tested whether selective hematopoietic USF1 deficiency can also beneficially impact the development of atherosclerosis. For this purpose, LDL receptor knockout mice were transplanted with bone marrow from USF1 knockout mice or their wild-type littermate controls and subsequently fed a Western-type diet for 20 weeks to stimulate atherosclerotic lesion development. Strikingly, absence of USF1 function in bone marrow-derived cells was associated with exacerbated blood leukocyte (+ 100%; P < 0.01) and peritoneal leukocyte (+ 50%; P < 0.05) lipid loading and an increased atherosclerosis susceptibility (+ 31%; P < 0.05). These effects could be attributed to aggravated hyperlipidemia, i.e. higher plasma free cholesterol (+ 33%; P < 0.001) and cholesteryl esters (+ 39%; P < 0.001), and the development of hepatosteatosis. In conclusion, we have shown that hematopoietic USF1 deficiency is associated with an increased atherosclerosis susceptibility in LDL receptor knockout mice. These findings argue against a contribution of macrophage-specific USF1 deficiency to the previously described beneficial effect of total body USF1 deficiency on atherosclerosis susceptibility in mice.Peer reviewe

Randomized controlled study of pain education in patients receiving radiotherapy for painful bone metastases

BACKGROUND: Although short-course radiotherapy is an effective treatment for patients with painful bone metastases, pain is not always sufficiently controlled. We therefore investigated the additional effect of a nurse-led pain education program on pain control and quality of life (QoL).PATIENTS AND METHODS: In this multicenter study, patients with solid tumor bone metastases and a worst pain intensity of ≥5 on a 0-10 numeric rating scale (NRS) were randomized between care as usual (control-group) and care as usual plus the Pain Education Program (PEP-group). PEP consisted of a structured interview and personalized education with follow-up phone calls. Patients completed the Brief Pain Inventory, EORTC QLQ-C15-PAL and BM22 at week 0, 1, 4, 8 and 12. The primary outcome was pain control, defined as the number of patients whose worst pain intensity was &lt;5 on a 0-10 NRS after 12 weeks. Secondary outcomes were time to reach control of pain (NRS &lt; 5), mean worst pain and average pain, and QoL at weeks 1, 4, 8 and 12.RESULTS: Of 308 included patients, 182 (92 PEP-group) completed 12 weeks follow-up. At 12 weeks, more patients in the PEP-group (71%) compared to the control-group (52%) reported pain control (P =.008). In the PEP-group, pain control was reached earlier than in the control-group (median 29 days versus 56 days; P =.003). Mean worst and average pain decreased in both groups but decreased more in the PEP-group. QoL did not differ between the groups.CONCLUSION: The addition of PEP to care as usual for patients treated with radiotherapy for painful bone metastases resulted in less pain and faster pain control.</p
