Squamous cell carcinoma (SCC) of the lip removed by surgery may cause lip dysfunction and scar. ALA-PDT (5-Aminolevulinic acid photodynamic therapy) is a minimally invasive treatment for superficial SCC in situ. However, few studies reported the use of topical ALA-PDT to manage lip SCC.
Between 2015 and 2017, 6 patients with Tis to T2 lip squamous cell carcinoma without evidence of lymph node spread, were treated with topical ALA-PDT at Shanghai Skin Disease Hospital. Clinical responses and side effect were evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST) at 1 month, 6 months, 12 months and 24 months after ALA-PDT.
All of the 6 patients achieved complete response (CR) by 2-7 sessions of ALA-PDT. There was no relapse during 24 months follow up for 4 patients. Two out of 6 patients relapsed at 10 months and 20 months post PDT but achieved CR again by 1-3 more sessions of PDT. There was no functional or aesthetic problem.
Topical 5-Aminolevulinic acid photodynamic could be considered a potential alternative therapeutic option for early-stage lip squamous cell carcinoma without lymph node spread.

To better understand this role, we evaluated recent outcomes for assets developed using different types of innovation. Although all approaches have delivered breakthroughs, assets that modulate established biological targets with innovative scientific or technological designs provide a unique combination of reduced development risk, high patient impact, and high commercial value. This type of asset currently represents a relatively small proportion of approved drugs and vaccines, but we anticipate that an increasing body of scientific knowledge and ongoing technological advancements could offer opportunities to grow this category in the future.Spiralling research costs combined with urgent pressures from the Coronavirus 2019 (COVID-19) pandemic and the consequences of climate disruption are forcing changes in drug discovery. Increasing the predictive power of in vitro human assays and using them earlier in discovery would refocus resources on more successful research strategies and reduce animal studies. Increasing laboratory automation enables effective social distancing for researchers, while allowing integrated data capture from remote laboratory networks. Such disruptive changes would not only enable more cost-effective drug discovery, but could also reduce the overall carbon footprint of discovering new drugs.The Internet of Things (IoT) applied to the treatment of cancer patients has been explored and the results are promising. This review aims to identify the applications and benefits of using IoT techniques, especially wearable devices, on the management of the adverse effects and symptoms, quality of life, and survival in cancer patients undergoing active treatment. The work also presents the architecture and taxonomy of the use of IoT, the challenges and the relevant results, as well as the association of the collected information with the type of treatment and the type of cancer. This study was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and considered articles from the last 10 years. Specific and general research questions and the PICOS approach were used to define the search string and to guide the selection of articles. The search retrieved 1678 publications, of which 121 were included for a full review. 67% of selected studies addressed the monitoring and follow-up of physical activities and their associations with the adverse effects and symptoms related to cancer treatment. Besides, 53% evaluated sleep patterns, heart rate, and oxygen saturation levels. One-third of the studies assessed patients with the indication for surgery and about one-half evaluated patients undergoing chemotherapy. Furthermore, the IoT allowed verifying associations of human behaviors with adverse effects and quality of life. IoT was observed to contribute to monitoring cancer patients, improve their quality of life and manage adverse effects related to cancer treatment. 53% were pilot studies and 93% were published in the last 5 years, which demonstrates to be a recent issue and therefore still has a lot to be explored.
To describe the real-world clinical use of ceftolozane/tazobactam (C/T) and associated outcomes in France.
Multicenter, prospective cohort study conducted in 22 hospitals. All adult patients who received at least one dose of C/T were asked to participate (2018-2019). Patients were treated according to standard hospital practice and followed up until C/T stop.
At the time of the analysis, 84 patients were evaluated. The median age was 64.8 years, and 67.9% (57/84) of patients were males. Fifty-seven patients (57/82, 69.5%) had one or more risk factors for multidrug-resistant (MDR) infections (missing MDR risk factor data for two patients). Most patients were critically ill and had several comorbidities. A majority (59/84, 70.2%) of patients had nosocomial infections. Half of all patients (n=42) had a diagnosis of pneumonia, of which 69% (29/42) were hospital acquired. Overall, 90.5% (76/84) of patients had MDR bacteria. Pseudomonas aeruginosa was the most frequently isolated bacterium (71/80, 88.8%), including 93% (80/86) of C/T-susceptible strains. C/T was prescribed as the first-line treatment to 29.8% (25/84) of patients. A concomitant antibiotic treatment was prescribed to 48.8% (41/84) of patients, of whom 65.9% (27/41) were prescribed concomitant antibiotics at the same time as C/T initiation. Empirical C/T prescription was microbiologically appropriate in 11/16 patients after susceptibility testing. selleck chemical Most patients (44/72, 61.1%) were cured and four (4/72, 5.6%) deaths were reported.
The results showed that C/T was most frequently prescribed for documented cases of P.aeruginosa infections. Most outcomes were positive, including among pneumonia patients.
