Standardization of robotic oesophagectomy can benefit both patients and surgeons by decreasing complications, shortening the learning curve and improving surgical training.

Thoraco-abdominal oesophagectomy with lymphadenectomy is the cornerstone of curative therapy for oesophageal carcinoma. To reduce post-operative morbidity, minimally invasive technology has become increasingly established. Conventional thoraco-laparoscopic procedures, however, are limited by their technical feasibility. These limitations can be overcome using robot-assisted technology.

Robotic Ivor-Lewis oesophageal resection has gradually been implemented in our clinic from 2013. We have performed over 250 robot-assisted minimally invasive oesophagectomies and more than 2000 robotic procedures overall. This experience allowed us to establish a standardized operative technique.

We identified 11 operative steps as key elements for oesophageal resection, which should help implementation of this technique and allow surgeons to approach this complex procedure with greater confidence.

Standardization is fundamental to the establishment of a new surgical technique and is a key element in the learning curve of Ivor-Lewis oesophageal resection. Standardization can lead to better reproducibility of results, and thus to improved quality.

Direct non-derivatization analysis of organic acids and acidic compounds by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) in positive ion mode is not always possible due to the low ionization efficiency of analytes. Some new efficient deprotonating matrices were suggested that allowed the production of negative ions from acidic compounds during MALDI-MS experiments.

Various tested carboxyl-containing compounds as well as compounds with acidic properties were mixed with the suggested deprotonating matrices [4-dimethylaminobenzaldehyde (DMABA), N,N-dimethylamino-p-phenylenediamine or 3-aminoquinoline] and applied on a standard MALDI target followed by recording MALDI mass spectra in negative ion mode.

All the tested acidic compounds mixed with the suggested deprotonating matrices produced abundant [M - H]
ions under MALDI conditions. DMABA produced the strongest signals reflecting greater sensitivity of analysis.

The suggested deprotonating matrices are commercially available compounds and are good alternatives to well-known matrices of this kind and, in particular, the often used 9-aminoacridine. DMABA is the best of the tested potential matrices and is suitable for the detection of low molecular weight carboxyl-containing compounds, substituted phenols, and mixtures of naphthenic acids by (-)MALDI-MS.

After that rehearsal, 53 members of the SVC among 61 in attendance were confirmed or strongly suspected to have contracted COVID-19 and two died. Transmission by the aerosol route is likely; it appears unlikely that either fomite or ballistic droplet transmission could explain a substantial fraction of the cases. It is vital to identify features of cases such as this to better understand the factors that promote superspreading events. Based on a conditional assumption that transmission during this outbreak was dominated by inhalation of respiratory aerosol generated by one index case, we use the available evidence to infer the emission rate of aerosol infectious quanta. We explore how the risk of infection would vary with several influential factors ventilation rate, duration of event, and deposition onto surfaces. The results indicate a best-estimate emission rate of 970 ± 390 quanta/h. MitoSOX Red research buy Infection risk would be reduced by a factor of two by increasing the aerosol loss rate to 5 h-1 and shortening the event duration from 2.5 to 1 h.The aim of the present study was to examine social cognition and social functioning in a group of amnestic mild cognitive impairment (aMCI) and Alzheimer's dementia (AD) patients. Thirty one people with aMCI, 29 individuals with AD, and 45 healthy older adults participated in the study. Facial expressions of happiness, anger, fear, disgust, and surprise presented in different intensities had to be labelled. Mentalizing was assessed using first-order belief theory of mind (ToM) stories and everyday social functioning by the Inventory of Interpersonal Situations (IIS), completed by an informant. aMCI patients were impaired in recognizing the emotions anger, disgust, and fear, while AD patients were impaired in recognizing the emotions anger, disgust, and surprise. More importantly, no significant differences between aMCI and AD patients were found on overall emotion recognition. Both the aMCI and AD patients were impaired on the ToM task, but no differences between the aMCI and AD patients were found. On everyday social functioning, only the AD patients showed impairments. No associations between the IIS and ToM were found, but the IIS and emotion perception were significantly correlated. Regression analysis taking all potentially confounding variables into account showed that only mood, but not the social-cognitive task performance or any other cognitive variable, predicted social functioning. aMCI and AD patients demonstrated impairments in mentalizing and facial emotion perception, and showed decrements in everyday social functioning. Informing caregivers about these deficits may help them to understand deficits in social cognition that may be present already in the MCI stage of Alzheimer's disease.Aerodigestive adverse effects (AD-AE) during intravenous pentamidine (IV-P) infusion for Pneumocystis jiroveci pneumonia prophylaxis are uncommon in retrospective chart review studies. We conducted a survey in patients on IV-P, which included 31 specific questions. Twenty-five patients were included in the analysis; AD-AE were observed in 22 (88%) with recurrence of symptoms in 88% participants with subsequent infusions. Five leading symptoms were congestion (48%), lip tingling (32%), nausea (28%), tongue tingling (24%), vomiting, and throat swelling (17%); multiple symptoms were reported in 72% of the patients. In conclusion, AD-AE of IV-P infusion are common, self-limited, and tend to be recurrent.
In this work, we evaluated the effects of light on growth, cell physiology and stress response of Azospirillum brasilense Az39, a non-photosynthetic rhizobacteria, under planktonic growth conditions.

Exponential cultures of Az39 were exposed to blue (BL), red (RL) and daylight (DL) or maintained in darkness for 24, 48 and 72h. The biomass production and indole 3-acetic acid (IAA) biosynthesis increased by exposition to DL. Conversely, BL decreased IAA concentration through a direct effect on the molecule. The DL increased superoxide dismutase activity, hydrogen peroxide and thiobarbituric acid reactive substances levels, but the last one was also increased by BL. Both DL and BL increased cell aggregation but only BL increased biofilm formation.

We demonstrated that both BL and DL are stress effectors for A. brasilense Az39 under planktonic growth conditions. The DL increased biomass production, IAA biosynthesis and bacterial response to stress, whereas BL induced cell aggregation and biofilms formation, but decreased the IAA concentration by photooxidation.

Blue light and DL changes growth capacity, cell physiology and plant growth promotion ability of A. brasilense Az39 and these changes could be considered to improve the production and functionality of biofertilizers.

Assess the feasibility of conducting a cluster randomized controlled trial (RCT) comparing technology-delivered mindfulness-based intervention (MBI) programs against a waitlist control arm targeting advanced cancer patients and their informal caregivers.

Two-arm cluster RCT within Kaiser Permanente Northern California. link2 We recruited patients with metastatic solid malignancies or hematological cancers and their informal caregivers. Intervention-group participants chose to use either a commercially available mindfulness app (10-20 min/day) or a webinar-based mindfulness course for 6 weeks. The waitlist control group received usual care. We assessed feasibility measures and obtained participant-reported data on quality of life (QoL; primary outcome) and distress outcomes (secondary) pre- and postintervention.

A hundred and three patients (median age 67 years; 70% female; 81% White) and 39 caregivers (median age 66 years; 79% female; 69% White) were enrolled. link3 Nearly all participants chose the mindfulness app over the webinar-based program. Among the participants in the intervention arm who chose the mobile-app program and completed the postintervention (6-week) survey, 21 (68%) patients and 7 (47%) caregivers practiced mindfulness at least 50% of the days during the 6-week study period. Seventy-four percent of intervention participants were "very" or "extremely" satisfied with the mindfulness program. We observed improvements in anxiety, QoL, and mindfulness among patients in the intervention arm compared to those in the control group.

We demonstrated the feasibility of conducting a cluster RCT of mHealth MBI for advanced cancer patients and their caregivers. Such remote interventions can be helpful particularly during the COVID-19 pandemic.

The distribution, utilisation and accessibility of surgical robotics in England is unknown.

A nationwide Freedom of Information (FOI) request was sent to all acute National Health Service (NHS) trusts. Accessibility was assessed for 32 843 Lower Super Output Areas in England.

All 149 acute NHS trusts responded to the FOI request. Sixty-one robots are distributed between 48 trusts. The number of robots and robotic procedures has increased annually. Urological procedures comprise 84.2% of robotic procedures. Procedure volume varies between robotic centres ranging from 1 to 683 in 2018. Over 2.4 million people have a travel time of over 1 hour to their nearest robotic centre.

National accessibility to robotic services and case volumes are variable and does not represent good value for the NHS. A national robotic surgery registry could improve the quality of robotic surgery and is needed to dynamically assess national provision of this technology.
