- The study aimed to determine the prevalence of hypomagnesemia (low magnesium levels) among asthmatic children compared to healthy controls.
- The mean serum magnesium level was found to be significantly lower in asthmatic children (1.91 mg/dL) than in healthy controls (2.03 mg/dL).
- Within the asthmatic group, serum magnesium levels decreased with increased asthma severity and inversely correlated with duration of asthma, though not significantly.
- The study concluded that asthmatic children have higher risk of magnesium deficiency and supplementation may help improve asthma outcomes.

ABSTRACT- Background: Esophageal and Lung carcinoma are the leading cause of years of life lost because of cancer and is associated with the highest economic burden relative to other tumor types. Epidemiological studies identify magnesium deficiency as a risk factor for these types of human cancers. The present studies were performed to concerning the contribution of magnesium to tumorigenesis and investigate the concentration of magnesium in esophageal and lung carcinoma.
Aims and Objective: The aim of this study was to compare the serum magnesium levels of patients with carcinoma of lung and esophagus patients and apparently healthy people.
Material and methods: Study group consisted of 50 clinically diagnosed subjects (Biopsy confirmed 25 cases with Esophageal carcinoma and 25 cases with Lung carcinoma). The control group consisted of 50 healthy subjects were included in the study. Venous blood samples of each lung and esophagus cancer were obtained and serum magnesium level was measured by Atomic Absorption Spectrophotometer measurements.
Results: In the study group, we were found mean concentration of serum magnesium was decreased in esophageal (1.40±0.13 mg %) and lung carcinoma (1.23±0.12 mg %) in comparison to controls (2.08 ± 0.45 mg %).
Conclusions: Serum magnesium was found statistically significantly lower in study group when compared with control (P<0.0001).

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Serum magnesium level in children with bronchial asthma
1.
2. • Introduction
• Aims of the study
• Patients and Methods
• Results & Discussion
• Conclusions & Recommendations.
3. Bronchial Asthma
• Asthma is a common chronic disease, causing
considerable morbidity.
• It is caused by chronic inflammation of lung airways
with increased airway responsiveness and airflow
obstruction.
• In 2007, 9.6 million children (13.1%) had been
diagnosed with asthma in their lifetimes.
• Boys (14% vs 10%) girls
• Children in poor families (16% vs 10% not poor) are
more likely to have asthma.
• Approximately 80% of all asthmatic patients report
disease onset prior to 6 yr of age.
4. Bronchial Asthma
• The rise in asthma and allergic disease among
children is a matter of worldwide concern.
• Many authors have argued that the changes in
diet may have been an important determinant
of increased susceptibility to asthma.
5. Magnesium
• Magnesium (Mg) is the fourth most abundant ion
in the human body; of which 50% is stored in the
• bones, 49% in cells and the remaining 1% in the
serum.
• Mg is involved in the structure of many enzymes
in the body and plays a role in intracellular
reactions.
• Mg is crucial for normal neuromuscular activities.
• Magnesium deficiency is associated with
increased contractility of smooth muscle cells
including bronchiolar resulting in bronchospasm.

23. Possible Explanation of Magnesium
Deficiency in Asthmatics
• Magnesium is the cofactor of more than 300 enzymes and is
involved in many physiological functions including protein synthesis,
intracellular signal distribution and enzyme catalysis.
• Since it is the natural antagonist of calcium, it provides smooth
muscle relaxation
• In addition, magnesium suppresses the excitability of muscle
fibers by reduction of acetylcholine secretion from motor nerve
terminals.
• Moreover, it inhibits production of inflammatory mediators by
helping stabilization of T-cells and inhibiting mast cell
degranulation.
• Again, it reduces the severity of inflammation in asthma by
stimulating nitric oxide and prostacyclin syntheses.
24. Possible Explanation of Magnesium
Deficiency in Asthmatics
• Although the cause of hypomagnesemia in
patients with bronchial asthma was unknown,
• It may be related to either low magnesium
intake in asthmatics or increased urinary loss
of magnesium, as a side effect of therapy with
b2- agonist, corticosteroid, and theophylline.
26. Conclusions
• Asthmatic Patients have significantly lower
mean Serum Mg levels compared with healthy
controls.
• There is significant difference between mean
Serum Mg levels AND severity of asthma.
• Serum Mg level inversely correlates with the
duration of asthma but not significantly.
• But no statistically significant association were
observed between Serum Mg and BMI.
• No significant change in serum Mg develops with
the use of steroids and bronchodilators in
treatment.
27. Recommendations
• Magnesium supplementation might be
considered a useful additional intervention for
improving outcome in patients with Asthma.
• A large follow up study is recommended to
look on the effect of Magnesium
supplementation in Asthmatic patients.
• Further extended cohort study is indicated to
look on the relations between the Asthmatic
patients and serum Magnesium level.
