    To Eat or Not to Eat Red Meat. A Closer Look at the Relationship Between Restrained Eating and Vegetarianism in College Females

    Previous research has suggested that vegetarianism may serve as a mask for restrained eating. The purpose of this study was to compare the dietary habits and lifestyle behaviors of vegetarians (n = 55), pesco-vegetarians (n = 28), semi-vegetarians (n = 29), and flexitarians (n = 37), to omnivores (n = 91), who do not restrict animal products from their diets. A convenience sample of college-age females completed questionnaires about their eating habits, food choice motivations, and personality characteristics. Results indicated that while vegetarians and pesco-vegetarians were more open to new experiences and less food neophobic, they were not more restrained than omnivores. Rather semi-vegetarians; those who restricted only red meat from their diet, and flexitarians; those who occasionally eat red meat, were significantly more restrained than omnivores. Whereas food choices of semi-vegetarians and flexitarians were motivated by weight control, vegetarians and pesco-vegetariansā€™ food choices were motivated by ethical concerns. By focusing specifically on semi-vegetarian and flexitarian subgroups, more effective approaches can be developed to ensure that their concerns about weight loss do not lead to unhealthful or disordered eating patterns

    Consecutive bilateral decompression retinopathy after mitomycin C trabeculectomy: a case report

    BACKGROUND: After a successful trabeculectomy, a sudden intraocular pressure decrease may alter the intracranial to intraocular pressure ratio and cause decompression retinopathy. Frequent Valsalva maneuvers may also play a role in its pathogenesis. This condition may manifest as multiple retinal hemorrhages, edema of the optic disc, macular edema, or a sudden decrease in visual acuity postoperatively. Outcomes for patients are usually good, with spontaneous resolution occurring within a matter of weeks. It has been rarely reported in the literature as a bilateral condition. CASE PRESENTATION: We present a case of consecutive bilateral decompression retinopathy in a 54-year-old severely obese Caucasian woman (body mass index 37 kg/m(2)) with open angle glaucoma and a poor history of medical therapeutic compliance, who chose surgical treatment based on her inability to consistently use ocular drops. Our patient underwent a trabeculectomy with mitomycin C in both eyes, with surgeries taking place 3 months apart. After the first surgery, 2 weeks postoperatively, she complained of decreased visual acuity. Examination of her right eye fundus revealed multiple retinal hemorrhages and disc edema. There was a similar pattern in her left eye, this time including maculopathy. Her visual acuity and fundoscopic changes resolved spontaneously over a period of a month in both cases. Currently, our patient has well-controlled bilateral intraocular pressure, ranging between 14 and 16 mmHg, without hypotensive medication. CONCLUSIONS: Decompression retinopathy is a potential complication after glaucoma surgery, but has rarely been described as a bilateral consecutive condition. A comprehensive approach could help to anticipate its occurrence and manage it.info:eu-repo/semantics/publishedVersio

    Measuring Quality of Mental Health Care: An International Comparison

    Get PDF
    The International Initiative for Mental Health Leadership (IIMHL) (www.iimhl.com) is a unique international collaborative that focuses on improving mental health and addiction services. IIMHL is a collaboration of eight countries including Australia, England, Canada, New Zealand, Republic of Ireland, Scotland, Sweden and USA. The project, ā€œMeasuring Quality of Mental Health Care: An International Comparisonā€, was initiated by a group of clinical experts under the auspices of the IIMHL Clinical Leaders Group. Led by Prof. Harold Pincus from Columbia University in New York, the project aims to not only raise awareness among clinicians and policymakers regarding the quality of care of the mental health systems they are working in, but ultimately to be able to compare system performance across countries to inform initiatives for transformation of mental health services

    Transport and recombination through weakly coupled localized spin pairs in semiconductors during coherent spin excitation

    Get PDF
    Semi-analytical predictions for the transients of spin-dependent transport and recombination rates through localized states in semiconductors during coherent electron spin excitation are made for the case of weakly spin-coupled charge carrier ensembles. The results show that the on-resonant Rabi frequency of electrically or optically detected spin-oscillation doubles abruptly as the strength of the resonant microwave field gamma B_1 exceeds the Larmor frequency separation within the pair of charge carrier states between which the transport or recombination transition takes place. For the case of a Larmor frequency separation of the order of gamma B_1 and arbitrary excitation frequencies, the charge carrier pairs exhibit four different nutation frequencies. From the calculations, a simple set of equations for the prediction of these frequencies is derived

    Electrical Detection and Magnetic-Field Control of Spin States in Phosphorus-Doped Silicon

    Electron paramagnetic resonance of ensembles of phosphorus donors in silicon has been detected electrically with externally applied magnetic fields lower than 200 G. Because the spin Hamiltonian was dominated by the contact hyperfine term rather than by the Zeeman terms at such low magnetic fields, superposition states Ī±āˆ£ā†‘ā†“>+Ī²āˆ£ā†“ā†‘> \alpha{}| \uparrow \downarrow >+\beta{}| \downarrow \uparrow > and āˆ’Ī²āˆ£ā†‘ā†“>+Ī±āˆ£ā†“ā†‘>-\beta{}| \uparrow \downarrow > + \alpha{}| \downarrow \uparrow > were formed between phosphorus electron and nuclear spins, and electron paramagnetic resonance transitions between these superposition states and āˆ£ā†‘ā†‘>| \uparrow \uparrow > or āˆ£ā†“ā†“>| \downarrow \downarrow > states are observed clearly. A continuous change of Ī±\alpha{} and Ī²\beta{} with the magnetic field was observed with a behavior fully consistent with theory of phosphorus donors in silicon.Comment: 6 pages, 5 figure
