To assess the presence of sublingual microcirculatory and skin perfusion alterations in COVID-19 pneumonia.

This is a preliminary report of a prospective observational study performed in four teaching intensive care units. We studied 27 mechanically ventilated patients with acute respiratory distress syndrome secondary to COVID-19. Sublingual microcirculation was assessed by hand-held videomicroscopy. A software-assisted analysis of videos was performed. We also measured capillary refill time.

Patients were hemodynamically stable with normal lactate (1.8 [1.6-2.5] mmol/L) and high D-dimer (1.30 [0.58-2.93] μg/mL). Capillary refill time was prolonged (3.5 [3.0-5.0] s). Compared to previously reported normal values, total and perfused vascular density (21.9±3.9 and 21.0±3.5mm/mm

) and heterogeneity flow index (0.91±0.24) were high; and the proportion of perfused vessels (0.96±0.03), microvascular flow index (2.79±0.10), and red blood cell velocity (1124±161μm/s) were reduced. The proportion of perfused vessels was inversely correlated with total vascular density (Pearson r=-0.41, P=0.03).

COVID-19 patients showed an altered tissue perfusion. Sublingual microcirculation was characterized by decreases in the proportion of perfused vessel and flow velocity along with high vascular densities. This last finding might be related to enhanced angiogenesis or hypoxia-induced capillary recruitment.

This study aimed to create a trigger tool for our intensive care units (ICUs) to support our departmental quality improvement efforts.

We compiled an initial list of triggers used in an ICU setting through literature review. We used a modified Delphi method to develop a unique set of triggers. An expert panel was selected for multidisciplinary and multi-site representation from four adult medical-surgical ICUs of a Canadian city. Respondents ranked triggers on a Likert scale based on its likelihood of being associated with adverse event (sensitivity to harm), and likelihood of being associated with suboptimal ICU processes (specificity for internal recommendations).

Our literature search yielded 10 articles and 59 triggers. Completion of the rating process resulted in 12 items that achieved consensus. Triggers included specific clinical, hospital-acquired infection, medication related, and procedural occurrences. One additional trigger (cardiopulmonary arrest) which consistently held high scores but did not achieve multidisciplinary consensus, was also included.

We used the modified Delphi process to derive consensus-selected triggers to identify ICU specific adverse events with opportunity for improvement in local care. This methodology can be adopted by other centers looking to introduce trigger tools in a manner selective to their practice needs.

Thus, the basic concept of basket trials (BTs) to target those genetic alterations with the same anti-tumour agents independent of the underlying tumour type was tumour agnostic. BTs can be divided into tumour gnostic, tumour semi-gnostic, and tumour agnostic trials which cover BTs of the conventional and the complex multiple-parallel type. At the beginning of the use of BTs, the expectation that they would function agnostically was dominating. This period was followed by an avalanche of experiments, analyses, and commentaries that underlined the importance of the microenvironment of tumours and thereby the impact of tissue also on molecularly targeted therapies. PDGFR inhibitor Intra-tumour heterogeneity with the phenomena of both intrinsic resistant cancer cell subclones and treatment-emergent acquired mutations that result in drug resistance as well as the co-occurrence of multiple potentially actionable molecular alterations within a tumour necessitate combinatorial treatment. However, this setting has only scarcely been addressed by BTs so far. Each of the various subtypes of BTs has contributed to meet the main goal of drug development, the approval of the agents tested. The position of BTs within the drug approval process and their potential impact on the off-label use of targeted agents are referred to as well. This review highlights the achievements reached with BTs along with failures. Selected issues of controversy are critically discussed, and potential solutions are addressed.

To evaluate the variability of growth hormone stimulation tests results and factors affecting it in short children suspected of having growth hormone deficiency.

The cohort included patients with short stature suspected of having growth hormone deficiency, and who underwent a second stimulation test, after the first stimulation test was positive. Testing was done at a single center from May 2014 to October 2017. Patients' weight, height, age, sex, stimulating agents and test results were recorded.

The study population comprised 200 patients, 108 males and 92 females, average age 9.2years (2.2-16.6years). The average peak growth hormone was 5.2μg/L and 7.8μg/L in the first and second tests respectively and the concordance rate was 56.5%. The probability of a second positive test was increased if the peak growth hormone level in the first test was below 5μg/L. In the second test, Clonidine and Glucagon led to higher peak growth levels than Arginine with averages of 9.02, 9.97 and 6.88μg/L respectively. Younger children and children with higher BMI SDS only had lower peaks of growth hormone in the second test. The effect of height SDS on peak growth hormone levels was equivocal.

The reproducibility rate of GH simulation tests in our study was low. A few factors may affect the peak levels of growth hormone in the second test, the most prominent being the peak of growth hormone in the first test.
