Arguments Used in Public Comments to Support or Oppose the US Department of Agriculture’s Minimum Stocking Requirements: A Content Analysis

Background

In 2016, the US Department of Agriculture (USDA)’s Supplemental Nutrition Assistance Program (SNAP) Retailer Rule proposed several changes for SNAP-authorized retailers, including: requiring retailers to have at least 85% of their food sales come from items that are not cooked or heated on site before or after purchase; requiring stores to stock seven varieties of qualifying foods from four staple food groups; requiring stores to carry perishable foods in three of the four staple groups; requiring stores to carry six units of qualifying foods at all times (depth of stock); disqualifying multiple ingredient foods and accessory foods from counting toward depth of stock requirements.

Health and medication literacy and the desire to participate in pharmacotherapy decision making – comparison of two countries

Background

Health and medication literacy may be important factors in the outcomes of medical treatment. Similarly, shared decision making or lack of it may influence patient's behavior and adherence to medications.

Salbutamol‐induced Decrease in Augmentation Index is Related to the Parallel Increase in Heart Rate

The change in augmentation index following salbutamol inhalation has been applied to evaluate endothelial function. We examined the contribution of salbutamol‐induced increase in heart rate to the observed decrease in augmentation index. Haemodynamics were recorded using whole‐body impedance cardiography and continuous pulse wave analysis from tonometric radial blood pressure. All subjects (n = 335, mean age 46, body mass index 26, 48% men) were without medications with cardiovascular influences. The effects of salbutamol inhalation (0.4 mg) versus the endothelium‐independent agent nitroglycerin resoriblet (0.25 mg) were examined during passive head‐up tilt, as the haemodynamic influences of these compounds depend on body position. Salbutamol decreased augmentation index by ~3‐4% units in supine and upright positions. Although salbutamol moderately increased cardiac index (+4.5%) and decreased systemic vascular resistance (?8.5%), the significant haemodynamic explanatory factors for decreased augmentation index in multivariate analysis were increased supine heart rate, and increased upright heart rate and decreased ejection duration (p < 0.001 for all, r² = 0.36–0.37). Sublingual nitroglycerin decreased supine and upright augmentation index by ~15% units and ~23% units, respectively. The haemodynamic explanatory factors for these changes in multivariate analysis were increased heart rate, reduced ejection duration and reduced systemic vascular resistance (p ≤ 0.021 for all, r² = 0.22–0.34). In conclusion, the lowering influence of salbutamol on augmentation index may be largely explained by increased heart rate, suggesting that this effect may not predominantly reflect endothelial function.     

Psychiatric nursing staffs’ attitudes towards the use of containment methods in psychiatric inpatient care: An integrative review

One of the international objectives in psychiatric care is reducing the use of coercion. Containment methods are meant to keep patients safe, yet usually include coercion. Nurses play a key role in deciding whether or not containment should be used and, as such, their attitudes towards containment can significantly impact the extent to which these methods are applied. The aim of this integrative review was to identify, analyse, and synthesize the available research on psychiatric nursing staffs’ attitudes towards containment methods in inpatient psychiatric care. An electronic search was conducted using the CINAHL, Scopus, and PsycINFO databases. In addition, the citations of identified studies were screened for relevant research. A total of 24 relevant papers published between 2002 and 2017 were selected for further analysis. These studies revealed variation in nursing staffs’ attitudes towards the use of containment methods. The use of containment methods seems to be widely accepted and nurses reported rarely considering alternative measures. It appears that attitudes towards containment have continuously become more negative, although the change has not been very pronounced. The concept of attitude was only defined in two studies. Thus, future research should strive to clarify this concept, as a generally accepted definition for attitude within nursing research and the utilization of all dimensions of this concept are both essential to the nursing field. Currently, it would be important to focus on changing attitudes among psychiatric nursing staff to reduce the use of containment methods; this calls for more research on nursing staffs’ attitudes.     

Brown adipose tissue function is accompanied by cerebral activation in lean but not in obese humans

Brown adipose tissue (BAT) is able to generate heat and dissipate energy in response to cold exposure in mammals. It has recently been acknowledged that adult humans also have functional BAT, whose metabolic activity is reduced in obesity. In healthy humans, the cerebral mechanisms that putatively control BAT function are unclear. By using positron emission tomography (PET), we showed that cold-induced BAT activation is associated with glucose metabolism in the cerebellum, thalamus, and cingulate, temporoparietal, lateral frontal, and occipital cortices in lean participants, whereas no such associations were found under warm control conditions. The cold-induced increase in cerebral glucose metabolism was more robust in lean than obese participants. Cerebral glucose metabolism was not associated with skeletal muscle or white adipose tissue glucose uptake under warm or cold conditions. In conclusion, BAT metabolism was accompanied by the activation of specific cerebral regions, and this shows an uncharacterized role that the brain plays in the regulation of BAT function. In obese participants, the cold-induced response in cerebral activity was attenuated that provides a clue for obesity-induced impairment in BAT metabolism.     

Hemodynamic effects of pindolol and atenolol at rest and during isometric exercise: A noninvasive study with healthy volunteers

Summary Hemodynamic effects of intravenous and oral pindolol and atenolol were assessed in ten healthy volunteers by left ventricular echocardiography and systolic time intervals. Measurements were made at rest and during hand-grip-induced isometric exercise. Drug doses were pindolol 0.015 mg/kg intravenously and 10 mg/day orally, atenolol 0.1 mg/kg intravenously, and 50 mg/day orally.Heart rate at rest was reduced by both drugs. The reduction caused by atenolol during oral treatment was significantly greater (p<0.01). Intravenously only pindolol reduced mean arterial pressure. During oral treatment atenolol reduced the mean arterial pressure nonsignificantly. Both drugs lowered heart rate during isometric exercise, atenolol being significantly more effective. During oral treatment atenolol blunted the heart-rate reaction to exercise. Mean arterial pressure during isometric exercise rose slightly with both drugs after intravenous administration. During oral treatment only atenolol reduced the mean arterial pressure significantly. Intravenous atenolol reduced cardiac contractility at rest, indicated by significant decreases in fractional shortening, ejection fraction, and the mean velocity of circumferential fiber shortening. In contrast, intravenous pindolol and oral therapy with either drug did not change contractility. Intravenous atenolol raised total peripheral resistance. The preejection period/left ventricular ejection time ratio decreased with intravenous pindolol, while atenolol increased it.In conclusion, atenolol had more negative inotropic and chronotropic effects, especially after acute intravenous administration. Only atenolol reduced cardiac output and increased peripheral resistance. After repeated oral administration, these effects were less apparent.     

Neoadjuvant and Adjuvant Systemic Therapy for Newly Diagnosed Stage II–IV Epithelial Ovary,Fallopian Tube,or Primary Peritoneal Carcinoma: A Practice Guideline

Background: This study aims to provide guidance for the use of neoadjuvant and adjuvant systemic therapy in women with newly diagnosed stage II–IV epithelial ovary, fallopian tube, or primary peritoneal carcinoma. Methods: EMBASE, MEDLINE, and Cochrane Library were investigated for relevant systematic reviews and phase III trials. Articles focusing on consolidation and maintenance therapies were excluded. Results: For women with potentially resectable disease, primary cytoreductive surgery, followed by six to eight cycles of intravenous three-weekly paclitaxel and carboplatin is recommended. For those with a high-risk profile for primary cytoreductive surgery, neoadjuvant chemotherapy can be an option. Adjuvant chemotherapy with six cycles of dose-dense weekly paclitaxel plus three-weekly carboplatin can be considered for women of Japanese descent. In women with stage III or IV disease, the incorporation of bevacizumab concurrent with paclitaxel and carboplatin is not recommended for use as adjuvant therapy unless bevacizumab is continued as maintenance therapy. Intravenous paclitaxel plus intraperitoneal cisplatin and paclitaxel can be considered for stage III optimally debulked women who did not receive neoadjuvant chemotherapy. However, intraperitoneal administration of chemotherapy with bevacizumab should not be considered as an option for stage II–IV optimally debulked women. Discussion: The recommendations represent a current standard of care that is feasible to implement and valued by both clinicians and patients.
