Antibacterial Activity
Authors: Al-Megrin Wafa Abdullah I. , El-Khadragy Manal F. , Mohamed Fatma A. , Ibrahim Hassan M. 
Published: May 2023

Aim:
The purpose of this paper is to synthesize and characterize two new direct dyes based on chromenes derivatives.

Background:
The synthesis of carboxyethyl chitosan (CECS) by the reaction of chitosan and acryl-ic acid via Michael's addition reaction was conducted. Cotton fabrics were treated with CECS to enhance the exhaustion of dye, fastness properties, and antimicrobial activity of dyed fabric.

Methods:
Chitosan (CS) and acrylic acid were combined in Michael’s addition process to success-fully produce N-carboxyethylchitosan (CECS). Then, the cotton was treated with different concen-trations of carboxyethyl chitosan (0.5–5 wt.%) and then dyed by synthesized mono azo and diazo direct dyes based on chromene derivatives.

Results and Discussion:
The results regarding dyeing and antibacterial activity indicated high-quality dyeing properties, However, direct dyes showed higher exhaustion and fixation values, fast-ness properties, and the colorimetric CIE L*a*b* C*h° data of the dyed cotton fabric.

Conclusion:
Cotton fabrics treated with carboxyethyl chitosan and dyed with direct dyes were found to have higher antibacterial activity upon a concentration of 2.5 wt.%. In addition, the anti-bacterial activity towards Gram-positive bacteria was reported to be more than Gram-negative bac-teria.

Authors: Gareri Pietro , Trevisan Caterina , Abbatecola Angela Marie , Malara Alba , Incalzi Raffaele Antonelli 
Published: May 2023

Background:
In older patients, prevention of acute respiratory tract infections (RTIs) is
challenging. Experimental studies have consistently underlined an immune-potentiating effect of
the bacterial lysates product OM85, on both cellular and humoral responses.

Objective:
This work aimed to assess the potential efficacy of OM-85 for RTIs’ prevention in older
individuals.

Methods:
This explorative longitudinal study included 24 patients aged 65 years or older recruited
in the GeroCovid Observational Study- home and outpatient care cohort. For the study purposes,
we included 8 patients treated with OM-85 from December 2020 to June 2021 (group A), and a
control group of 16 patients, matched for sex and age, who did not receive bacterial lysates (group
B). RTIs were recorded from the participants’ medical documentation in an e-registry from March
2020 to December 2021.

Results:
In 2020, group A experienced a total of 8 RTIs, which affected 6 out of 8 patients (75%);
group B reported 21 RTIs, with at least one event in 11 out of 16 patients (68.7%). In 2021, RTIs
affected 2 out of 8 patients (25%) in group A (p < 0.02), and 13 out of 16 patients (81.2%) in group
B (within this group, 5 patients had two RTIs). The RTIs' cumulative incidence over the
observation period significantly differed between groups (66.7% in group A vs. 24.3% in group B;
p < 0.002), as well as the decrease in RTIs frequency from 2020 to 2021. No patients in group A
were affected by COVID-19 during the observation period, while among controls, two patients had
SARS-CoV-2 infection, notwithstanding three doses of vaccine.

Conclusion:
This study suggests that bacterial lysates may provide clinical benefits for preventing
RTIs. Additional research involving larger cohorts is required to verify the effectiveness of OM-85
in preventing RTIs in older adults.

Authors: Sharma M.  , Sujata S.  , Bansal D.  , Kaushik P.  
Published: May 2023

Abstract::
For biomass production and bioremediation, Algae have been extensively exploited for biosensing
in wastewater monitoring. Their advantages include the coupling of suitable bioreceptor for monitoring
photosynthesis oxygen, their potential to be integrated into dual transduction miniaturized devices
and detect the effect due to pollutants present in water with continuous monitoring of the environment.
Microalgae are photosynthetic microorganisms that are very sensitive and reactive toward any change in
the environment. And also able to detect any trace amount of pollutants. The performance of algal biosensors
towards pollutants represents a good alternative to other developing sensors. In the algal biosensor,
the algal cell is entrapped in galling material (Alginate, Carrageenan) and immobilized cells for stabilization
with ions (Ca2+, K+). Genetically modified biosensor overcomes the limitation of natural biosensor.
Whole-cell biosensors are highly sensitive to herbicides in wastewater, and many other bioreceptor of
algal cells those sensitive to different types of pollutants. The present algal sensor is much smaller, valid
support in smart agriculture, environmentally friendly and less expensive, the easily accessible.

<p> </p>
<p><u>Objective:</u> To estimate the global, regional, and national prevalence of prediabetes defined by impaired glucose tolerance (IGT) or impaired fasting glucose (IFG). </p>
<p><u>Research Design and Methods:</u> We reviewed 7,014 publications for high-quality estimates of IGT (2-hour glucose, 7.8-11.0 mmol/L [140-199 mg/dL]) and IFG (fasting glucose, 6.1-6.9 mmol/L [110-125 mg/dL]) prevalence for each country. We used logistic regression to generate prevalence estimates for IGT and IFG among adults aged 20-79y in 2021 and projections for 2045. For countries without in-country data, we extrapolated estimates from countries with available data with similar geography, income, ethnicity, and language. Estimates were standardized to the age distribution for each country from the United Nations.</p>
<p><u>Results:</u> Approximately two-thirds of countries did not have high-quality IGT or IFG data. There were 50 high-quality studies for IGT from 43 countries, and 43 high-quality studies for IFG from 40 countries. Eleven countries had data for both IGT and IFG. The global prevalence of IGT in 2021 was 9.1% (464 million) and is projected to increase to 10.0% (638 million) in 2045. The global prevalence of IFG in 2021 was 5.8% (298 million) and is projected to increase to 6.5% (414 million) in 2045. The 2021 prevalence of IGT and IFG were highest in high-income countries. In 2045, the largest relative growth in cases of IGT and IFG was in low-income countries.</p>
<p><u>Conclusions:</u> The global burden of prediabetes is substantial and growing. Enhancing prediabetes surveillance is necessary to effectively implement diabetes prevention policies and interventions.</p>

Published: May 2023

Introduction: Supracondylar humerus fracture is one of the most found fractures in children. In addition to adequate fixation, the role of age differences in the clinical outcomes of operative treatment of supracondylar humeral fractures is still a matter of debate. This study aimed to compare the clinical and radiological outcome of surgery in cases of Gartland type III supracondylar humerus fracture.

Materials and Methods: This study used a cross-sectional design on the population of patient with Gartland type III supracondylar fracture. Patients were divided into 2 groups: age <5 years old (Group 1) and >5 years old (Group 2). The evaluation was carried out 3 months after surgery with open reduction internal fixation crisscross wire. The parameters assessed were Baumann’s angle, carrying angle, and anterior humeral line, and Disabilities of the Arm, Shoulder, and Hand (DASH) Score. Difference between group were analyzed using the chi-square test.

Results: There were a total of 34 patients included in this study. Patients >5 years old had a 1.85 times greater chance to have a post-operative carrying angle of >15o (95% CI 0.993-3.474; p = 0.037) and 2.75 times greater chance to result in post-operative Baumann’s angle >80o (95% CI 1,089-6,943, p=0.037). There were no significant differences in anterior humeral line (p=1) and DASH score (p=0.244) between groups.

Conclusion: The result of surgery in supracondylar fracture of the humerus over 5 years old tend to have worse radiological outcome (carrying angle and Baumann’s angle) than patient younger than 5 years old. Thus, treatment of supracondylar fractures of the humerus aged more than 5 years requires more attention with adequate reduction and vigilance against complications that can affect the bone growth of pediatric patients.
