The carbon footprint of a UK University during the COVID-19 lockdown

The COVID-19 pandemic has provided a unique opportunity to compare the carbon intensity of higher education delivered on- and off-campus. This is attributed to governmental lockdown orders that have forced Universities to close their campuses, ban business travel and move all teaching and learning activities online. This study represents the first known attempt to compare the carbon footprint of a mid-sized UK University produced during the COVID-19 lockdown (April-June 2020) against that generated within the respective time period in previous years. Although the overall carbon footprint of the University decreased by almost 30% during the lockdown, the carbon intensity of online teaching and learning was found to be substantial and almost equal to that of staff and student commute in the pre-lockdown period. The study contributed to an emerging academic discourse on the carbon (dis)benefits of different models of higher education provision in the UK and beyond. The study suggested that policy and management decisions on transferring education online should carefully consider the carbon implications of this transfer.

An Examination of Specific Types of Ijime within Japanese Schools

Multiple suicides among Japanese students due to bullying have resulted in the initiation of various mechanisms to prevent, manage and measure the prevalence of bullying (ijime). Ijime is now a problem of epidemic proportions in Japan. Due to the historical roots of collectivism, combined with the rapid industrialization of Japan, the manifestation of bullying is very different from that seen in Western cultures. The Japanese government, through Mombusho (Japanese Ministry of Education, Sport and Culture), and the Japan Center for Family and Child Research, has attempted to respond to the ever increasing incidence of ijime among Japanese students. In an effort to both augment the level of response, as well as increase the scope of understanding, a fellowship was established to facilitate the ability of a foreign professor to research the issue of ijime. This manuscript informs the prevalence and types of ijime-related behaviours, and presents the findings of related interviews and focus groups conducted in Japan. Differences in behaviours at the elementary, junior high and high school educational levels are discussed.

Increasing HIV-related knowledge, communication, and testing intentions among Latinos: Protege tu Familia: Hazte la Prueba

Latinos are less likely to be aware of their HIV seropositivity than African Americans and Whites. 'Protege tu Familia: Hazte la Prueba' is a culturally and linguistically-sensitive HIV/AIDS prevention and testing program targeting Latino families. Using community-based participatory research techniques, Spanish-speaking bicultural community health workers helped develop and then used an educational flip chart and materials to conduct outreach and HIV prevention education in diverse settings. The intervention was created to increase HIV/AIDS-related knowledge, to improve communication regarding sexual risk, and to augment intentions to use condoms and test for HIV. A secondary purpose was to decrease HIV-related stigma by improving knowledge about transmission and reducing homophobia. Participants demonstrated significant increases in HIV knowledge, intention to practice safer sex and communicate sexual risk to partner(s), and intention to test for HIV. Improvements were also found in self-reported comfort levels when interacting with and caring for the HIV positive, thus decreasing HIV/AIDS-related stigma.

[Dabigatran (Pradaxa): efficacy and safety]

There is considerable interest in developing new, orally available anticoagulants for the prevention and treatment of thrombotic disorders. In Europe, the low-molecular-weight heparins (LMWHs) are more commonly prescribed for thrombosis prevention, but require parenteral administration, platelets monitoring twice a week during the first month. Furthermore, LMWH are not synthetic. All of these characteristics can be an obstacle to optimal patient care, particularly when outpatient dosing is required after early discharge. New oral anticoagulants that require no monitoring and can be administered in a fixed dose without drug-drug and drug-food interactions would clearly offer practical advantages if shown to be safe and effective. dabigatran étexilate, a new oral, direct thrombin inhibitor, is the prodrug of the active compound dabigatran, which binds reversibly to thrombin with high affinity and specificity. This agent has a rapid onset of action, a predictable and reproducible that permit once-daily dosing. To date, more than 8,000 patients have been studied in clinical trials, and more than 38,000 individuals are enrolled in ongoing trials. Three major prospective, randomized, double-blind non-inferiority trials have compared the efficacy and safety of dabigatran étexilate (150 mg or 220 mg once-daily) starting postoperatively, with subcutaneous enoxaparin, in patients undergoing hip (RE-NOVATE trial) or knee arthroplasty (RE-MOBILIZE and RE-MODEL). Based on these trial results, dabigatran étexilate is approved for use in the European Union and Canada for primary prevention of VTE in patients having undergone elective total hip and knee arthroplasty. Pradaxa is now on the market in France since December 2008.

Adherence to a new oral anticoagulant treatment prescription: dabigatran etexilate

The recent development of new oral anticoagulants, of which dabigatran etexilate is currently at the most advanced stage of development, is the greatest advance in the provision of convenient anticoagulation therapy for many years. A new oral anticoagulation treatment, dabigatran etexilate, is already on the market in Europe. The main interest probably will be to improve the prescription and the adherence to an effective thromboprophylaxis in medical conditions such as atrial fibrillation without bleeding side effects, without the need for monitoring coagulation, and without drug and food interactions such as vitamin K anticoagulant (VKA) treatment. Dabigatran is particularly interesting for extended thromboprophylaxis after major orthopedic surgery in order to avoid daily injection for a month. However, oral long-term treatments such as VKA are not systematically associated with a higher compliance level than injected treatments such as low-molecular-weight heparins. Indeed, adherence to an oral treatment, instead of the usual daily injection in major orthopedic surgery, is complex, and based not only on the frequency of dosing but also on patient motivation, understanding, and socio-economic status. New oral anticoagulants may be useful in this way but education and detection of risk factors of nonadherence to treatment are still essential.

Quantitative determination of C-polysaccharide in Streptococcus pneumoniae capsular polysaccharides by use of high-performance anion-exchange chromatography with pulsed amperometric detection

Capsular polysaccharides of Streptococcus pneumoniae are used to formulate polyvalent pneumococcal vaccines. A sensitive method, using high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD), has been developed to quantify the contamination of pneumococcal capsular polysaccharides (PnPs) with the C-polysaccharide (C-Ps). As this polysaccharide is highly immunogenic, and since anti C-Ps antibodies are not protective, the need to monitor and reduce its level is of uppermost importance. The method is based on the quantification by HPAEC-PAD of ribitol, which is released by a two-step hydrolysis of the PnPs using aqueous hydrofluoric acid (HF) followed by trifluoroacetic acid hydrolysis (TFA). This simple method has been shown to provide both qualitative and quantitative information about the purity of polysaccharide preparations.
