Manufacturing and characterization of III-V on silicon multijunction solar cells

Tandem GaInP/GaAs//Si(inactive) solar cells were manufactured by direct wafer bonding under vacuum. At this early stage, an inactive silicon substrate was used (i.e. n+ Si substrate instead of an active n-p Si junction). Bonded devices presented an Sshaped J-V curve with a kink close to Voc caused by a built-in potential barrier at the III-V//Si interface that reduces the fill factor and therefore the efficiency of the device by 7% compared to the stand-alone GaInP/GaAs tandem cells. Nevertheless, losses in Jsc and Voc caused by the bonding process, account for less than 10%. AlGaAs single junction cells, designed to be bonded on a silicon cell for low concentrator photovoltaics (LCPV), were also manufactured reaching an efficiency of 15.9% under one sun AM1.5G spectrum for a 2 cm² cell

Benefits and harms of perioperative high fraction inspired oxygen for surgical site infection prevention: a protocol for a systematic review and meta-analysis of individual patient data of randomised controlled trials.

INTRODUCTION The use of high fraction of inspired oxygen (FiO2) intraoperatively for the prevention of surgical site infection (SSI) remains controversial. Promising results of early randomised controlled trials (RCT) have been replicated with varying success and subsequent meta-analysis are equivocal. Recent advancements in perioperative care, including the increased use of laparoscopic surgery and pneumoperitoneum and shifts in fluid and temperature management, can affect peripheral oxygen delivery and may explain the inconsistency in reproducibility. However, the published data provides insufficient detail on the participant level to test these hypotheses. The purpose of this individual participant data meta-analysis is to assess the described benefits and harms of intraoperative high FiO2compared with regular (0.21-0.40) FiO2 and its potential effect modifiers. METHODS AND ANALYSIS Two reviewers will search medical databases and online trial registries, including MEDLINE, Embase, CENTRAL, CINAHL, ClinicalTrials.gov and WHO regional databases, for randomised and quasi-RCT comparing the effect of intraoperative high FiO2 (0.60-1.00) to regular FiO2 (0.21-0.40) on SSI within 90 days after surgery in adult patients. Secondary outcome will be all-cause mortality within the longest available follow-up. Investigators of the identified trials will be invited to collaborate. Data will be analysed with the one-step approach using the generalised linear mixed model framework and the statistical model appropriate for the type of outcome being analysed (logistic and cox regression, respectively), with a random treatment effect term to account for the clustering of patients within studies. The bias will be assessed using the Cochrane risk-of-bias tool for randomised trials V.2 and the certainty of evidence using Grading of Recommendations, Assessment, Development and Evaluation methodology. Prespecified subgroup analyses include use of mechanical ventilation, nitrous oxide, preoperative antibiotic prophylaxis, temperature (2.5 hour). ETHICS AND DISSEMINATION Ethics approval is not required. Investigators will deidentify individual participant data before it is shared. The results will be submitted to a peer-review journal.

Late delivery of antibiotics: a new proxy for antimicrobial stewardship?

International audienceOBJECTIVES: To analyse the time elapsed between the prescription of antibiotics and their pick-up at the pharmacy and identify their determinants. METHODS: We used the National Health Insurance reimbursement databases on antibiotics delivery in 2021 in La Manche, Western France. Delayed delivery was defined as the time between prescription and antibiotic pick-up of >24 hours. RESULTS: We enrolled 207 250 prescriptions, of whom 18 728 (9.0%) collected their antibiotics at the community pharmacy >24 hours after prescription. Independent factors associated with delayed delivery were age >15 years (15-64 years: OR, 2.08 [1.98-2.19]; p < 0.001 and >65 years OR, 3.27 [3.09-3.46]; p < 0.001), male sex (OR, 00.77 [0.75-0.80]; p < 0.001), low income (OR, 1.08 [1.02-1.15]; p = 0.013), chronic diseases (OR, 1.29 [1.25-1.34]; p < 0.001), prescription during the weekend (OR, 1.49 [1.43-1.56]; p < 0.001), summer season (OR, 1.11 [1.07-1.16]; p < 0.001), lock-down period (OR, 4.15 [3.80-4.53]; p < 0.001), and distance from the patient home to his general practitioner office and the pharmacy >10 km (OR, 1.17 [1.13-1.21]; p < 0.001). DISCUSSION: The delayed delivery of antibiotics after prescription is not uncommon, especially in elderly patients, those with low income or chronic diseases, in case of weekend prescriptions, summer season and when the pharmacy is > 10 km away from the patient’s home and his general practitioner office. If confirmed, this potential indicator of unnecessary prescriptions, readily available in some databases, may be used to target antimicrobial stewardship programmes and monitor the effect of interventions
