58, p=0.017). The DR in patients with caudal septal deviation was significantly decreased by OSR (0.14±0.06 to 0.03±0.03, p=0.004), but not by KI (0.09±0.08 to 0.04±0.03, p=0.25). OSR also improved nasal airway resistance (1.10±0.44 to 0.42±0.15, p=0.02), and the VAS score (79.11±14.74 to 5.78±7.89, p=0.004).

Nasal obstruction is more severe in patients with the caudal deviation. OSR corrects caudal deviation of the nasal septum more effectively than does KI. The AP could be useful for the evaluation of the deviation of the nasal septum and help in selecting the appropriate septoplastic technique.

Some concerns have been raised regarding the safety of SARS-CoV-2 vaccines, largely based on case-reports of serious thromboembolic events after vaccination. Some mechanisms have been suggested which might explain the adverse cardiovascular reactions to SARS-CoV-2 vaccines. Different vaccine platforms are currently available which include live attenuated vaccines, inactivated vaccines, recombinant protein vaccines, vector vaccines, DNA vaccines and RNA vaccines. Vaccines increase the endogenous synthesis of SARS-CoV-2 Spike proteins from a variety of cells. Once synthetized, the Spike proteins assembled in the cytoplasma migrate to the cell surface and protrude with a native-like conformation. These proteins are recognized by the immune system which rapidly develops an immune response. Such response appears to be quite vigorous in the presence of DNA vaccines which encode viral vectors, as well as in subjects who are immunized because of previous exposure to SARS-CoV-2. The resulting pathological features may resemble those of active coronavirus disease. The free-floating Spike proteins synthetized by cells targeted by vaccine and destroyed by the immune response circulate in the blood and systematically interact with angiotensin converting enzyme 2 (ACE2) receptors expressed by a variety of cells including platelets, thereby promoting ACE2 internalization and degradation. These reactions may ultimately lead to platelet aggregation, thrombosis and inflammation mediated by several mechanisms including platelet ACE2 receptors. Whereas Phase III vaccine trials generally excluded participants with previous immunization, vaccination of huge populations in the real life will inevitably include individuals with preexisting immunity. This might lead to excessively enhanced inflammatory and thrombotic reactions in occasional subjects. Further research is urgently needed in this area.Not requested.

To objectively assess the quality of “crisis communication” media, during the COVID-19 pandemic, in the three Greater Maghreb countries (Tunisia, Algeria, Morocco).

A compliance audit for press releases and epidemiological bulletins was analyzed against a quality benchmark, which had been specifically designed by the authors. This framework, made up of five dimensions and 50 items, graded (0/1), was applied by two researchers in preventive medicine. Multiplying the scores by a coefficient of two resulted in a partial score of 20 points for each dimension and a total score of 100 points for the checklist taken as a whole. The quality of the communication media was considered to be good when exceeding the thresholds of 15/20 for the different dimensions and 75/100 for the entire grid.

A total of 141 information media were included in this audit (Tunisia 60; Algeria 60; Morocco 21). The overall median quality score for these media was only 56/100 (IIQ [46-58]), without major variability between countries. pensable and should be considered as an urgent matter.While synthetic microbial systems are becoming increasingly complicated, single-strain systems cannot match the complexity of their multicellular counterparts. Such complexity, however, is much more difficult to control. find more Recent advances have increased our ability to control temporal, spatial, and community compositional organization, including modular adhesive systems, strain growth relationships, and asymmetric cell division. While these systems generally work independently, combining them into unified systems has proven difficult. Once such unification is proven successful we will unlock a new frontier of synthetic biology and open the door to the creation of synthetic biological systems with true multicellularity.The coronavirus disease 2019 (COVID-19) pandemic can cause reverse zoonoses (i.e., human-animal transmission of COVID-19). It is vital to utilize up-to-date methods to improve the control, management, and prevention of reverse zoonoses. Awareness of reverse zoonoses should be raised at both individual and regional/national levels for better protection of both humans and animals.Tropical secondary forests are increasingly important for carbon sequestration and biodiversity conservation worldwide; yet, we still cannot accurately predict community turnover during secondary succession. We propose that integrating niche differentiation and dispersal limitation will generate an improved theoretical explanation of tropical forest succession. The interaction between seed sources and dispersers regulates seed movement throughout succession, and recent technological advances in animal tracking and molecular analyses enable us to accurately monitor seed movement as never before. We propose a framework to bridge the gap between niche differentiation and dispersal limitation. The Source-Disperser Limitation Framework (SDLF) provides a way to better predict secondary tropical forest succession across gradients of landscape disturbance by integrating seed sources and frugivore behavior.

Hepatitis C virus (HCV) infection is one of the most frequent causes of liver transplantation (LT) worldwide. Patients with HCV viremia at the time of LT universally develop recurrent HCV in the allograft, leading to accelerated fibrosis and graft loss. Treatment with direct-acting antivirals (DAA) is highly effective and safe in this population.

To describe the efficacy and safety of DAA in treating post LT HCV recurrence in a Mexican cohort.

We designed a retrospective cohort study that included all LT patients from 2000-2019 with HCV recurrence after LT who received DAA. Clinical and biochemical characteristics were collected from clinical records. Patients who received treatment before LT and those who received interferon-based therapies after LT achieving sustained viral response at 12 weeks were excluded; patients who didn´t complete DAA therapy were eliminated. The primary outcome was SVR-12.

Fifty-six patients received DAA after the LT with 98% SVR-12. The most frequent genotypes were 1b (54%) and 1a (34%).
