Triple negative breast cancer (TNBC) is an area of high unmet medical need in terms of new effective treatment strategies. Although breast cancer is traditionally considered a 'cold' tumor type, TNBC is the most appropriate subtype for immunotherapeutic strategies; this is due to the high level of tumor infiltrating lymphocytes, PD-L1 expression, and tumor mutational burden compared to other breast cancer subtypes.

This review examines the available evidence on the use of immunotherapeutic strategies in early and advanced TNBC, discusses the pitfalls and limitations often encountered in clinical research, and summarizes data on novel promising immunomodulatory approaches that have been explored in early-phase trials.

PD-1-blockade is approved for stage II/III TNBC and for first-line treatment of PD-L1-positive TNBC patients with metastatic disease and should be considered standard of care. However, question marks and difficulties remain; these include the identification of predictive biomarkers to selecined Positive Score (CPS); disease control rate (DCR); neoadjuvant chemotherapy (NACT); pathological complete response (pCR); event-free survival (EFS); disease-free survival (DFS); residual cancer burden (RCB); San Antonio Breast Cancer Symposium (SABCS); antibody-drug conjugates (ADCs); PARP inhibitors (PARPi); clinical benefit rate (CBR); Histone deacetylase inhibitors (HDACi); Dendritic cell (DC); talimogene laherparepvec (TVEC); granulocyte-macrophage colony-stimulating factor (GM-CSF); mismatch repair deficiency (dMMR).
The use of high flow nasal cannula (HFNC) has become widely used in pediatric intensive care units (PICUs) throughout the world. The rapid adoption has outpaced the number of studies evaluating the safety and efficacy in a variety of pediatric diseases/conditions.

This scoping review begins with the definition and mechanisms of action of HFNC and then follows with a review of the literature focused on studies performed on critically ill children cared for in the PICU. The PubMed database was searched with a pediatric filter from the time period 2000 to 2021.

The rapid adoption of HFNC in PICUs has largely been driven by changes in institutional practices and small observational studies. There is a lack of adequately powered studies evaluating patient-centered outcomes, such as intubation rates, mortality, PICU, and hospital length of stay. Given the wide variability in flow rates and clinical indications, more research is needed to better define effective flow rates for different disease states as well as markers of treatment success and failure. One particular entity that is poorly studied is the use of HFNC in those at risk for developing pediatric acute respiratory distress syndrome (PARDS).

In the increasingly challenging field of clinical microbiology, diagnosis is a cornerstone whose accuracy and timing are crucial for the successful management, therapy, and outcome of infectious diseases. Currently employed biomarkers of infectious diseases define the scope and limitations of diagnostic techniques. As such, expanding the biomarker catalog is crucial to address unmet needs and bring about novel diagnostic functionalities and applications.

This review describes the extracellular nucleases of 15 relevant bacterial pathogens and discusses the potential use of nuclease activity as a diagnostic biomarker. Articles were searched for in PubMed using the terms 'nuclease,' 'bacteria,' 'nuclease activity' or 'biomarker.' For overview sections, original and review articles between 2000 and 2019 were searched for using the terms 'infections,' 'diagnosis,' 'bacterial,' 'burden,' 'challenges.' Informative articles were selected.

Using the catalytic activity of nucleases offers new possibilities compared to established biomarkers. Nucleic acid activatable reporters in combination with different transduction platforms and delivery methods can be used to detect disease-associated nuclease activity patterns
and
for prognostic and diagnostic applications. Even when these patterns are not obvious or of unknown etiology, screening platforms could be used to identify new disease reporters.

Despite substantial progress in the field, malaria remains a global health issue and currently available control strategies are not sufficient to achieve eradication. Agents able to prevent transmission are likely to have a strong impact on malaria control and have been prioritized as a primary objective to reduce the number of secondary infections. Therefore, there is an increased interest in finding novel drugs targeting sexual stages of
and innovative methods to target malaria transmission from host to vector, and vice versa.

This review covers innovative transmission-blocking inventions patented between 2015 and October 2021. The focus is on chemical interventions, which could be used as 'chemical vaccines' to prevent transmission (small molecules, carbohydrates, and polypeptides).

Even though the development of novel strategies to block transmission still requires fundamental additional research and a deeper understanding of parasite sexual stages biology, the research in this field has significantly accelerated. Among innovative inventions patented over the last 6 years, the surface-delivery of antimalarial drugs to kill transmission-stages parasites in mosquitoes holds the highest promise for success in malaria control strategies, opening completely new scenarios in malaria transmission-blocking drug discovery.

To explore the pregnancy outcomes of women who couldn't obtain effective results from noninvasive prenatal testing (NIPT) and examine the factors leading to test failure.

From April 2017 to December 2019, 120,041 pregnant women enrolled for voluntary NIPT. The case group comprised of 274 (274/120,041) women who failed to obtain effective NIPT results, and the control group (
=540) was from the same population who obtained effective NIPT results and matched by age at a 12 ratio. Abnormal pregnancy rates between the two groups were analyzed using Chi-square analysis. NIPT failure risk factors were analyzed using logistic regression analysis.

Logistic regression analysis showed that increased maternal age (OR=0.988; 95% CI=0.982-0.994), increased pregnancy age (OR=0.989; 95%CI=0.988-0.991), and decreased cell-free fetal DNA concentration (OR=1.050; 95%CI=1.043-1.058) were independent risk factors for NIPT failure. Fifteen cases showed fetus loss in cases of NIPT failure. There was a significant difference in abnormal pregnancy rate between the NIPT success and failure groups (χ2=50.943, P <0.05).

The specific interventions, guidance, and precautions are needed for pregnant women who have no effective NIPT results.

Copy number variations (CNVs) are commonly associated with malignancies, including hereditary breast and ovarian cancers. Next generation sequencing (NGS) provides solutions for CNV detection in a single run. This study aimed to compare the accuracy of CNV detection by NGS analyzing tool against Multiplex Ligation Dependent Probe Amplification (MLPA).

In total, 1276 cases were studied by targeted NGS panels and 691 cases (61 calls in 58 NGS-CNV positive and 633 NGS-CNV negative cases) were validated by MLPA.

Twenty-eight (46%) NGS-CNV positive calls were consistent, whereas 33 (54%) calls showed discordance with MLPA. Two cases were detected as SNV by the NGS and CNV by the MLPA analysis. In total, 2% of the cases showed an MLPA confirmed CNV region in
. The results of this study showed that despite the high false positive call rate of the NGS-CNV algorithm, there were no false negative calls. The cases that were determined to be negative by the NGS and positive by the MLPA were actually carrying SNVs that were located on the MLPA probe binding sites.

The diagnostic performance of NGS-CNV analysis is promising; however, the need for confirmation by different methods remains.

The first COVID-19 wave started in February 2020 in France. The influx of patients requiring emergency care and high-level technicity led healthcare professionals to fear saturation of available care. In that context, the multidisciplinary
thics-
upport
ell (EST) was created to help medical teams consider the decisions that could potentially be sources of ethical dilemmas.

The primary objective was to prospectively collect information on requests for EST assistance from 23 March to 9 May 2020. The secondary aim was to describe the Cell's functions during that period.

This observational, real-time study of requests for Cell consultations concerned ethical dilemmas arising during a public health crisis. The EST created a grid to collect relevant information (clinical, patient's/designated representative's preferences and ethical principles strained by the situation), thereby assuring that each EST asked the same questions, in the same order.

Only our university hospital's clinicians could request Eighlights ethical risks, enhances the added-value of nursing and encourages all players to be vigilant to pursue collective deliberations to achieve clear and transparent decisions.
COVID-19 crisis forced hospitals to envisage prioritization of ICU access. Established decision-making criteria and protocols do not enable healthcare professionals to escape ethical dilemmas. That acknowledgement highlights ethical risks, enhances the added-value of nursing and encourages all players to be vigilant to pursue collective deliberations to achieve clear and transparent decisions.
