Pseudohalide Ions as Ligands to Tune Architecture and Luminescence of Polymetallic CU(I) Assemblies.

The reaction of preassembled Cu(I) bimetallic units {Cu(dppm)} and {Cu(dppa)} (dppm: bis(diphenylphosphino)methane and dppa: bis(diphenylphosphino)amine) with pseudohalide linkers (azido, dicyanamide, and tricyanomethanide) allows for the quantitative and selective preparation of three discrete tetrametallic metallacycles of formula [Cu(μ-dppm)(N)](PF), [Cu(μ-dppm)(N(CN))](PF), and [Cu(μ-dppm)(C(CN))]. To explore further the impact of the linker on the architecture and dimensionality of the molecular edifice, the study was extended to more sophisticated tetradentate cyanocarbanion ligands (tcnsMe: 2-(methylthio)-1,1,3,3-propanetetracarbonitrile and tcnsEt: 2-(ethylthio)-1,1,3,3-propanetetracarbonitrile). Three ladder-like one-dimensional coordination polymers and an octametallic metallacycle have been obtained.

Circulation patterns and molecular epidemiology of human respiratory syncytial virus over five consecutive seasons in Morocco.

Background: Respiratory syncytial virus (HRSV) is the leading cause of respiratory tract infections in infants and young children. we investigated the prevalence and characteristics of HRSV in Morocco and explored trends in circulating genotypes through partial G gene analysis of HRSV strains prevalent from 2012 to 2017.

Methods: Respiratory samples were gathered from both outpatients and inpatients meeting ILI or SARI case definitions.

Factors associated with hospitalization for seasonal influenza in Morocco.

Background: Morocco is actively working towards expanding its influenza vaccine policy to cover high-risk groups, as recommended by the World Health Organization (WHO).

Aims: We assessed the risk factors for influenza-associated hospitalization for severe acute respiratory infections (SARI) that occurred during the last 5 seasons.

Methods: We conducted a retrospective, analytical study among patients recruited in the ambulatory and hospital sites of the influenza sentinel surveillance system in Morocco between 2014 and 2019.

Influenza-associated severe acute respiratory infections among children under five years old in Morocco, September 2017 to March 2019.

The main aim of this research is to investigate the trend of influenza infection among children under 5 years with severe acute respiratory infections (SARI) as well as those who suffer from a high burden of disease. This research is based on a survey conducted from September 2017 to March 2019. During this period nasopharyngeal swabs were collected in a group of 942 children under 5 years with SARI, admitted in pediatric services of 8 sentinel hospitals.

Design and Rationale of the National Observational Multicentric Tunisian Registry of Hypertension: Protocol for Evaluating Hypertensive Patient Care in Clinical Practice.

Background: This study was designed to evaluate the care of hypertensive patients in daily clinical practice in public and private centers in all Tunisian regions.

Objective: This study will provide us an overview of hypertension (HTN) management in Tunisia and the degree of adherence of practitioners to international recommendations.

Methods: This is a national observational cross-sectional multicenter study that will include patients older than 18 years with HTN for a duration of 4 weeks, managed in the public sector from primary and secondary care centers as well as patients managed in the private sector.
