Content of macro- and microelements in rats with experimental autoimmune thyroiditis and under the influence of lemna minor

The aim was to study the effect of aqueous extract and 30 % alcohol tincture of Lemna minor frond (AELM and TLM) on the content of macro- and microelements in rats with experimental autoimmune thyroiditis. Materials and methods. The effect of AELM and TLM was studied in a model of experimental autoimmune thyroiditis in rats, induced by immunization with human thyroid antigen. The serum levels of total thyroxine, total triiodothyronine, antibodies to thyroglobulin, antibodies to thyroperoxidase, and concentrations of macro- and microelements were studied. Results. The development of experimental autoimmune thyroiditis led to a decrease in the content of total thyroxine and antibodies to thyroperoxidase in the blood serum, an increase in the content of antibodies to thyroglobulin and a decrease in the concentrations of sodium, chlorine, potassium phosphorus, zinc, copper, iron and magnesium. It was found that the use of AELM and TLM against the background of autoimmune thyroiditis led to the restoration of T4 and elemental balance in rats, which was manifested in an increase in the content of sodium, chlorine, phosphorus, magnesium, zinc, iron, copper and calcium in the blood serum. It was also shown that TLM had a more powerful effect on the normalisation of the content of such elements as chlorine, potassium, copper and zinc. The obtained effect of AELM and TLM on the content of macro- and microelements in the blood serum of animals with experimental AIT can be explained by their positive effect on the functional activity of the thyroid gland. The studied extract and tincture may also affect other physiological and biochemical processes due to the content of macro- and microelements and other biologically active substances, which requires further research. Conclusions. Administration of AELM and TLM to rats with experimental AIT contributed to lowering the level of Anti-TG and restoring the thyroid and elemental status in the animals' blood serum. The obtained research data allow us to recommend AELM and TLM as a regulator of the elemental status of the body in case of changes in thyroid function

Associations of Serum Mineral levels of Copper, Magnesium and Calcium with Skeletal Muscle mass and Strength in Chinese children, aged 6-11: A Cross-Sectional Study

Background: Skeletal Muscle Mass (SMM) and strength are crucial for children's health, and low SMM can lead to adverse health outcomes. A deficiency of essential minerals can cause poor growth, fractures or osteoporosis. The study aimed to explore the relationship between serum Calcium (Ca), Copper (Cu), and Magnesium (Mg) levels and SMM in Chinese children. Methods: 466 primary school children were recruited for a cross-section study aged 6-11 in Guangzhou City, South of China, from December 2015 to February 2017. The study conducted whole-body dual-energy x-ray absorptiometry (DXA) scans using the Hologic discovery W to obtain the Total skeletal mass (TSM) and appendicular skeletal mass (ASM) were calculated, which were used as parameters to calculate variables of Skeletal muscle mass (SMM). Results: Of the 466 primary school children, 266 were boys and 200 girls with mean ages of 8.00±1.00 years for boys and 8.08±0.97 years for girls. An increase in mean Cu serum concentration between the T1 and T3 in girls resulted in 3.19% (P- trend =0.034, P-diff =0.083), 3.57% (P- trend =0.037, P-diff=0.083), 2.44% (P- trend =0.018, P=diff=0.060) and 2.25% (P- trend =0.024, P-diff= 0.072) for ASM/Height, ASH/ Weight, TSM/ Height and TSM/ Weight respectively, No significant mean difference was observed between serum Cu and ASM, TSM, ASM/ AFM and TSM/TFM (P- trend >0.05). A significant mean difference in serum Mg levels and ASM/ AFM for the total and boys' group was observed, with 6.68% and 9.44% (P- trend =0.042 and 0.041) respectively. No significant mean differences were seen between all the variables of serum Ca levels and all the variables of skeletal muscle mass and strength. Conclusions: Serum copper levels influence the development of SMM in girls, but not in boys. Serum Ca and Mg level in girls and boys do not influence SMM development among children aged 6-11.

Serum Magnesium Levels in Patients Admitted with Septic Shock and Their Correlation with Outcome

Objective: To evaluate the initial serum magnesium levels of critically ill septic shock patients upon admission to the intensive care unit (ICU) and correlate these levels with the patients' requirements and outcomes, including ventilator support, length of stay in the ICU, occurrence of cardiac arrhythmias, and mortality rates.Methods: This was an observational study involving 60 patients who were admitted to the medical Intensive Care Unit (ICU) for septic shock. Serum magnesium levels were measured upon admission to the ICU. A comparison was made between patients with normal and abnormal magnesium levels at the time of admission to evaluate the need for vasopressor support, the average duration of assisted ventilation and dialysis, the incidence of arrhythmia, the average length of ICU stay, and mortality rates.Results: Out of the 60 cases studied, there were 42 males (70.00%) and 18 females (30.00%), resulting in a M:F ratio of 1:0.42. The mean age of both male and female patients was found to be comparable. The need for assisted ventilation and renal replacement therapy was found to be comparable in patients with normal and abnormal serum magnesium levels. The number of days for which assisted ventilation was required, the incidence of arrhythmia, the mean duration of ICU and hospital stay, and mortality were significantly higher in patients with abnormal magnesium levels at the time of ICU admission (P<0.05).Conclusion: Abnormal serum magnesium levels are associated with increased morbidity and mortality in critically ill septic shock patients admitted to the ICU.

Effects Of Magnesium Oxide Treatment On Serum Electrolyte Levels In Constipated Children

Background: Magnesium oxide (MgO) is a standard treatment for functional constipation. However, this medication has not been evaluated extensively for possible alterations of plasma magnesium (Mg) levels and other electrolytes. This retrospective study aimed to appraise the effects of serum magnesium with some other electrolyte levels after oral MgO treatment in children with functional constipation.
 Methodology: After the approval of the local ethical committee, archives of the patients who had been admitted to two different Pediatric Surgery outpatient clinics in different cities between 2014-2018 were evaluated. The demographic findings of the patients were recorded. For the diagnosis of chronic constipation, Rome-III classification criteria were used. After complete physical examinations, if there were no possible organic reasons other than chronic dietary problems, serum electrolyte levels were obtained and evaluated. Findings were evaluated statistically and discussed with the literature.
 Result: The magnesium value was significantly higher in the constipation group (p

Hypophosphatemia and Type-2 Diabetes Mellitus: A Review

Type-2 diabetes is a global public health crisis that threatens the economies of all nations, particularly developing countries. Type-2 diabetes mellitus has been suggested to be the most common endocrine disorder associated with several metabolic disturbances including changes in serum calcium, zinc, magnesium, or phosphate. Moreover, those who have poor glycemic control and longtime diabetes mellitus are more likely to decrease the blood phosphate level. Low serum phosphate level may be associated with morbidity and mortality from cardiovascular disease in these patients. So, the findings of this study may suggest that serum phosphate is an important screening parameter in type-2 diabetic patients especially who have poor glycemic control and longtime diabetes mellitus.

Citrate-Buffered, Magnesium-Enriched Dialysate on Calcification Propensity in Hemodialysis Patients – The CitMag Study

IntroductionSerum calcification propensity (T50 time) is associated with mortality in dialysis patients. Several solitary interventions improve T50, but whether a combination of interventions yields further increases in T50 is unknown. We hypothesized that a combination of two interventions, namely increasing magnesium concentration while simultaneously substituting acetate for citrate in the dialysis fluid, leads to increases in T50 values. MethodsIn a randomized, controlled trial, 60 chronic hemodialysis patients were allocated to either continue on standard (S) dialysate (3 mmol/l acetate, 0.5 mmol/l magnesium) or a sequence of magnesium-enriched (Mg0.75) dialysate (3 mmol/l acetate, 0.75 mmol/l magnesium) for 2 weeks followed by combination treatment using citrate-buffered, magnesium-enriched (Cit+Mg0.75) dialysate (1 mmol/l citrate, 0.75 mmol/l magnesium) for 3 weeks. The primary endpoint was the difference in T50 times between the S group and the Cit+Mg0.75 group. ResultsThere was no significant difference in T50 time between the S group compared to the Cit+Mg0.75 group (236 ± 77 vs. 265 ± 97 minutes, p=0.23). The size of secondary calciprotein particles (CPP-2Rh) did not differ between the S group and the Cit+Mg0.75 group (294 ± 95 vs. 309 ± 91 nm, p=0.56). In longitudinal analyses, serum magnesium concentrations increased from 1.07 ± 0.17 to 1.24 ± 0.17 mmol/l with the Mg0.75 dialysate (p<0.0001) but decreased again to 1.19 ± 0.16 mmol/l with the Cit+Mg0.75 dialysate (p<0.0001). ConclusionThe combination of citrate-buffer with increased magnesium concentration in dialysate does not improve T50.

Serum Calcium and Magnesium Levels in Patients with Type 2 Diabetes and COVID-19 Infection Requiring Hospitalization—Correlations with Various Parameters

The purpose of this research was to analyze the impact of SARS-CoV-2 infection on ionic calcium, total calcium and serum magnesium upon hospital admission, taking into account the association of type 2 diabetes as a metabolic comorbidity. Our study included 57 patients: a group of 28 patients without diabetes, but with SARS-CoV-2 virus infection, and a second group of 29 patients with type 2 diabetes and SARS-CoV-2 virus infection. The serum level of calcium and magnesium of the patients included in the study did not differ statistically significantly in those with type 2 diabetes compared to those without type 2 diabetes who were infected with the SARS-CoV-2 virus at the time of hospitalization. Ionic calcium, total calcium, and serum magnesium did not statistically significantly influence the survival of the patients with COVID-19 infection included in this research, but the type of infection severity (mild or moderate) did influence the survival rate. Concerning the diabetic patients, a statistically significant correlation was found between serum total calcium and total serum proteins, and another one between ionic calcium and uric acid, urea, and total cholesterol. Serum total calcium and D-dimers were statistically significantly correlated with being transferred to the intensive care unit. On the other hand, magnesium significantly correlated with lipids (triglycerides, total lipids) and inflammatory (fibrinogen, ESR) biomarkers.

Cardiotoxicity Induced by Capecitabine and Oxaliplatin in Gastric Cancer Treatment: A Rare Case of Cardiac Arrest and Cardiogenic Shock.

Combination-based adjuvant chemotherapy utilising capecitabine and oxaliplatin is widely used in gastric cancer treatment. Rare but severe cardiac events such as prolonged QT, cardiac arrest and cardiogenic shock can result from their use. A 45-year-old female with gastric adenocarcinoma was started on capecitabine-oxaliplatin chemotherapy one week before presenting to the emergency department with weakness. Blood pressure was 78/56 mmHg, heart rate 140 bpm and oxygen saturation 85%. She became unresponsive with pulseless ventricular fibrillation; CPR was initiated with immediate intubation. She received two shocks with a return of spontaneous circulation. Laboratory tests revealed serum potassium (3.1 mmol/l), magnesium (1.1 mg/dl) and troponin (0.46 ng/ml). An EKG revealed sinus tachycardia with a prolonged QT interval (556 ms). The combined effects of capecitabine, oxaliplatin and electrolyte abnormalities likely contributed to the QT prolongation. An echocardiogram demonstrated an ejection fraction of 10%-15%. An emergent right-heart catheterisation showed right atrial pressure of 10 mmHg and pulmonary artery pressure of 30/18 mmHg; cardiac output and index were not recorded. An intra-aortic balloon pump was placed, and she was admitted to the ICU for cardiogenic shock requiring norepinephrine, vasopressin and dobutamine. A repeat echocardiogram showed a significantly improved ejection fraction of 65%, and she was discharged. Capecitabine and oxaliplatin cardiotoxicity is an exceedingly rare occurrence, with both drugs reported to cause QT prolongation. Healthcare providers must recognise the QT prolongation effects of capecitabine and oxaliplatin, leading to life-threatening cardiac arrhythmias. Recognise the QT-prolonging effects of capecitabine and oxaliplatin-based chemotherapy.Recognise that cardiogenic shock and cardiac arrest with capecitabine and oxaliplatin-based chemotherapy can occur in individuals with benign cardiac history, especially early in treatment.

Association of serum magnesium levels with renal prognosis in patients with chronic kidney disease.

Magnesium deficiency is associated with various health conditions, but its impact on the progression of chronic kidney disease (CKD) remains unclear. This study aimed to investigate the association between serum magnesium levels and prognosis of renal function in CKD patients. This is an analysis of the Japan Chronic Kidney Disease Database Ex (J-CKD-DB-Ex), which is a multicenter prospective cohort including CKD patients enrolled from January 1, 2014 to December 31, 2020. We included adult outpatients with CKD stage G3 and G4 at the time of initial magnesium measurement. Patients were classified by magnesium levels as low (<1.7mg/dl), normal (1.7-2.6mg/dl), or high (>2.6mg/dl). The primary outcomes were the composite of an eGFR<15ml/min/1.73m2 or a ≥30% reduction in eGFR from the initial measurement, which was defined as CKD progression. We applied the Kaplan-Meier analysis and Cox regression hazard model to examine the association between magnesium levels and CKD progression. The analysis included 9868 outpatients during the follow-up period. The low magnesium group was significantly more likely to reach CKD progression. Cox regression, adjusting for covariates and using the normal magnesium group as the reference, showed that the hazard ratio for the low magnesium group was 1.20 (1.08-1.34). High magnesium was not significantly associated with poor renal outcomes compared with normal magnesium. Based on large real-world data, this study demonstrated that low magnesium levels are associated with poorer renal outcomes.

Magnesium and Memory: Unraveling the Physiological Tapestry of Alzheimer's Disease

Background: Alzheimer disease is the leading cause of Dementia throughout the world. There are multiple researches are undergoing globally to understand the etiology of this disabling disease. Magnesium is another suspicious factor that might produce this disease. Objectives: The study was aimed to evaluate possible association between serum magnesium and Alzheimer disease. Methodology: This case control study was conducted in the emergency Department in collaboration of Medical OPD of Liquate University Hospital Hyderabad from January 2023 to December 2023. 300 participants were divided into control, 200 participants and 100 in the test group. Serum Magnesium was evaluated into both control and test group. Graph Pad Prism 9 was used to detect P value. Significance of variable was considered below 0.05. Results: Those who were suffering from Alzheimer disease shows more Hypomagnesaemia (p-value= 0.001) than normal patients. The low serum Magnesium level was found 3.1 times greater (Odds ratio= 5.5, likelihood ratio= 1.9) in Alzheimer patients Conclusion: there is a specific association between Hypomagnesaemia and Alzheimer disease.

Evaluation of Prognostic Significance of Serum Magnesium Level in Patients with Acute Myocardial Infarction

Background: Magnesium has been considered an important factor in the pathogenesis of acute myocardial infarction and its complications. Magnesium ions are essential for the maintenance of the functional integrity of the myocardium. It also improves vascular tone, afterload and cardiac output, and decreases peripheral vascular resistance and cardiac arrhythmias. Serum magnesium concentration has great significance in the prognosis of acute myocardial infarction (MI). Aim and objective: This study aimed to assess the relation of low serum magnesium levels with post-infarction complications of acute MI. Methods: This cross-sectional descriptive study was conducted in the Department of Pharmacology &amp; Therapeutics, Rajshahi Medical College in collaboration with the Cardiology department between July 2019 to June 2020. Assessment and comparison of the serum magnesium level of the patients on the 5th day of post-infarction with the 1st day of admission in 50 patients of acute MI was done in this study. Results: The mean magnesium level was 2.25 ± 0.15 mg/dl in patients without any complications which was significantly higher than the patients who had multiple complications. The level of magnesium was 1.79 ± 0.37 mg/dl in complicated cases. (P˂0.001). These observations suggest that in acute myocardial infarction, patients with low magnesium levels are more prone to develop complications. Conclusion: So it can be concluded that measurement of serum magnesium levels has prognostic significance and magnesium treatment can be implicated in patients of acute myocardial infarction with low magnesium levels.

Serum electrolyte concentrations and risk of atrial fibrillation: an observational and mendelian randomization study

BackgroundAtrial fibrillation (AF) is a prevalent arrhythmic condition resulting in increased stroke risk and is associated with high mortality. Electrolyte imbalance can increase the risk of AF, where the relationship between AF and serum electrolytes remains unclear.MethodsA total of 15,792 individuals were included in the observational study, with incident AF ascertainment in the Atherosclerosis Risk in Communities (ARIC) study. The Cox regression models were applied to calculate the hazard ratio (HR) and 95% confidence interval (CI) for AF based on different serum electrolyte levels. Mendelian randomization (MR) analyses were performed to examine the causal association.ResultsIn observational study, after a median 19.7 years of follow-up, a total of 2551 developed AF. After full adjustment, participants with serum potassium below the 5th percentile had a higher risk of AF relative to participants in the middle quintile. Serum magnesium was also inversely associated with the risk of AF. An increased incidence of AF was identified in individuals with higher serum phosphate percentiles. Serum calcium levels were not related to AF risk. Moreover, MR analysis indicated that genetically predicted serum electrolyte levels were not causally associated with AF risk. The odds ratio for AF were 0.999 for potassium, 1.044 for magnesium, 0.728 for phosphate, and 0.979 for calcium, respectively.ConclusionsSerum electrolyte disorders such as hypokalemia, hypomagnesemia and hyperphosphatemia were associated with an increased risk of AF and may also serve to be prognostic factors. However, the present study did not support serum electrolytes as causal mediators for AF development.

Spleen white pulp structural and cellular composition in experimental furosemide-­induced hypomagnesemia

Relevance. Magnesium deficiency in the blood (hypomagnesemia) is due to many reasons, among which loop diuretics (furosemide) occupy acertain place. The role of the spleen in this process has not been determined. The aim of the work was to elucidate the effect of furosemide-­induced hypomagnesemia on the immune structures of the white pulp of rat spleen. Materials and Methods. Furosemide (Lasix® Aventis Pharma Ltd, India) was injected daily intraperitoneally at adose of 30 mg/kg to the experimental group of white outbred rats for 6 days, animals of the control group received an injection of 0.9% NaCl. Investigated: blood serum for the content of magnesium, calcium, sodium and iron; serial sections of the white pulp of the spleen after staining with hematoxylin and eosin to assess the structure and azure-­II-eosin to assess the cellular composition. With amicroscope magnification of 280 times, the ratio (in%) of primary (PLNS) and secondary lymphoid nodules of the spleen (SLNS) was calculated, the following were measured (µm): the diameter of the germinal center (GC), the width of the mantle and marginal zone, the diameter of the periarteriolar lymphoid sheath (PALS). In GC, the peripheral zone of lymphoid nodules, PALS at amagnification of 1500 times per field of view (100 μm2) was counted and presented as apercentage of the number of lymphocytes; macrophages; cells, mitotic and apoptotic elements. Morphometric analysis was carried out using Image ProPlus6.0 software (Media Cybernetics, USA). Statistical processing was carried out using the Statistica 10.0 software package with the determination of the arithmetic mean (M) and its error (m). Results and Discussion. The administration of furosemide led to adecrease in magnesium in the blood serum by 1.6 times (p0.05). In the white pulp of the spleen of animals of the experimental group, the proportion of SLNS decreased by 18.14%, the number of SLNS increased by 42.5% (p0.05). The diameter of SLNS increased insignificantly, the diameter of GC and the width of the marginal zone significantly increased by 27.1 and 24.8%, respectively. The proportion of macrophages increased by 20.6% in GC SLNS, and by 17.0% in PALS. The highest increase in the proportion of cells with signs of apoptosis was found in the periarteriolar lymphoid sheath of experimental animals - 34.6% (p0.05). Conclusion. Furosemide loading causes the development of dyselementosis, with the most significant loss of magnesium (hypomagnesemia) and has apronounced effect on the immune parameters of the spleen, represented by white pulp structures. Therefore, correction of the elemental status and monitoring of the state of the spleen in hypomagnesemia caused by the use of loop diuretics is anecessary element in the prevention of complications associated with the use of diuretic drugs.

Long-term complications of permanent hypoparathyroidism in adults: prevalence and associated factors.

Patients with Chronic hypoparathyroidism (CHPT) receiving conventional treatment are exposed to several long-term complications including basal ganglia calcifications, posterior subcapsular cataract, kidney stones, and renal insufficiency. The aim of this study was to assess the prevalence and the associated factors of these complications in patients with CHPT. We conducted a cross-sectional study including 58 patients with CHPT. All participants underwent physical examination, biochemical assessment (total serum calcium, serum phosphorus, serum albumin, intact-PTH, serum magnesium, 25-hydroxy-vitamin D, serum creatinine, thyroid stimulating hormone (TSH), and 24-hour urinary calcium), slit lamp examination, brain computed tomography scan (CT-scan), and renal ultrasound. Participants had a mean age of 52.6 ± 16.4 years and a gender ratio (women/men) of 3.5. Fahr syndrome, cataract, urolithiasis, and renal failure were found in 55%, 62%, 12%, and 17% of cases, respectively. CHPT duration >15 years (Adjusted-OR = 43.1, 95-CI: 2.63-703.06, p = 0.008) and poor adherence to treatment (Adjusted-OR = 8.04, 95%-CI: 1.52-42.42, p = 0.014) were independently associated with the risk of Fahr syndrome. Age >55 years (adjusted-OR = 5.07, 95-CI: 1.10-23.42, p = 0.037), disease duration >15 years (adjusted-OR = 20.21, 95-CI: 1.54-265.84, p = 0.022), and magnesium level <0.8 mmol/l (adjusted-OR = 36.46, 95-CI: 3.75-354.08, p = 0.002) were independently associated with the risk of subcapsular cataract. Only hypercalciuria (Adjusted-OR = 21.27, 95-CI: 2.31-195.91, p = 0.007) was an independent risk factor for kidney stones. Renal failure was not associated with kidney stones (p = 1). However, creatinine clearance was negatively correlated with age (r = -0.784; p < 10-3) and disease duration (r = -0.352; p = 0.007). Our results revealed high prevalences of neurological, ocular, and renal complications in patients with CHPT and emphasized the importance of regular biological monitoring, therapeutic adjustments, screening, and adherence to treatment in the prevention of these complications.

Epidemiology, risk factors, outcomes, and role of Serpin A3 as a biomarker for transition of acute kidney injury to chronic kidney disease in critically ill patients

BackgroundSeveral studies have suggested a causal link between acute kidney injury and the consequent development of chronic kidney disease. The severity, frequency, and duration of acute injury are key factors in this process.AimsThis study aimed to determine the epidemiology and outcomes of AKI to CKD transition in critically ill adult patients and to study the role of Serpin-A3 in the early recognition of AKI to CKD transition.MethodsIn this prospective observational study, a total of 252 patients attending Assiut University Hospitals Critical Care Unit and developed AKI during their stay were recruited. Serum and urinary Serpin A3 were measured by ELISA Kit. Complete blood picture, kidney function tests, urine analysis, serum electrolytes (serum sodium, potassium, calcium, phosphorus, and magnesium), liver function test, coagulation profile, C-reactive protein, 24-h urinary protein or urinary albumin/creatinine ratio, abdominal ultrasound were assessed for all the recruited participants. Follow-up was done for three consecutive months and after 3 months using serum creatinine, BUN, and serum potassium.ResultsIt was found that old age is a risk factor for CKD following AKI, i.e., with 1-year increase in the patient’s age, there was 3% increase in the chance of transition. Significant association was found between rate of comorbidity and transition status. Also, cases with either infection or IV radio contrast exposure were 2.8 and 6.5 times more liable for transition. Cases with transition in this study had significantly higher renal function parameters. Higher median levels of Serpin A3 either serum or urinary was reported in transition patients. Improvement was reported in two-third of those without transition, and higher mortality rate was recorded in those without transition.ConclusionThe frequency of transition was 20%. Older age, male gender, cardiac and CVS disease, the presence of infection, higher BUN and creatinine level, higher median K and PO4 levels, and higher median levels of Serpin A3 are risk factors for transition from AKI to CKD.

Association of Postpartum Depression with Maternal Serum Magnesium Levels, Infant Growth, and Neurodevelopmental Indices.

Postpartum depression (PPD) can exert both short-term and long-term effects on a child's health. Offspring born to mothers who suffer from PPD face an elevated susceptibility to encountering psychological disturbances and developmental delays. Moreover, there has been conjecture surrounding a plausible connection between maternal magnesium (Mg) levels and psychiatric manifestations. This study aims to investigate the relationship between maternal Mg levels and PPD and the correlation between PPD and an infant's growth and neurodevelopment at 6 and 12 months. This longitudinal study is a sub-study derived from the "PERSIAN Birth Cohort Study," encompassing 224 mother-infant pairs randomly enlisted during 2019-2020 in Isfahan. Maternal serum magnesium (Mg) levels were measured at 38 weeks of gestation. PPD was evaluated employing the Edinburgh Postpartum Depression Scale (EPDS) four weeks postpartum. Measurements of birth size were undertaken, adhering to standardized protocols at birth, 6 months, and 12 months. Anthropometric parameters and the Persian version of the validated Ages and Stages Questionnaires (ASQ) were employed to assess infant neurodevelopmental status at 6 and 12 months. Overall, 22.3% of mothers grappled with PPD. The mean (standard deviation) maternal magnesium levels (Mg) were 1.95 ± 0.23 mg/dL. No statistically significant association was detected between maternal serum magnesium (Mg) levels and the incidence of PPD. Correspondingly, no significant association emerged between PPD and indices of growth. However, a noteworthy distinction materialized in the communication scores of offspring born to depressed and non-depressed mothers following adjustments for confounding variables at 12 months (β = 1.81; 95% confidence interval: 0.32-3.30). Furthermore, a substantial regression in communication skills became apparent between 6 and 12 months. This study failed to establish a significant association between maternal serum magnesium (Mg) levels and PPD. Nevertheless, research lends credence to an inverse correlation between maternal depression and subsequent behavioral difficulties in offspring, such as communication skills. Thus, the imperative nature of screening for PPD should be underscored to facilitate its early detection and intervention, thereby enhancing infant well-being.

Magnesium supplementation modulates T-cell function in people with type 2 diabetes and low serum magnesium levels.

Low magnesium levels, which are common in people with type 2 diabetes, are associated with increased levels of pro-inflammatory molecules. It is unknown whether magnesium supplementation decreases this low-grade inflammation in people with type 2 diabetes. We performed a multidimensional immunophenotyping to better understand the effect of magnesium supplementation on the immune system of people with type 2 diabetes and low magnesium levels. Using a randomized, double-blind, placebo-controlled, two-period, cross-over study, we compared the effect of magnesium supplementation (15 mmol/day) to placebo on the immunophenotype including whole blood immune cell counts, T-cell and CD14+ monocyte function after ex vivo stimulation, and the circulating inflammatory proteome. We included 12 adults with insulin-treated type 2 diabetes (7 males, mean±SD age 67±7 years, BMI 31±5 kg/m2, HbA1c 7.5±0.9 %) and low magnesium levels (0.73±0.05 mmol/l). Magnesium treatment significantly increased serum magnesium and the urinary magnesium excretion, when compared to placebo. The IFN-γ production from PMA/ionomycin stimulated CD8+ T-cells and T-helper 1 cells, as well as the IL4/IL5/IL13 production from T-helper 2 cells was lower after treatment with magnesium compared to placebo. Magnesium supplementation did not affect immune cell numbers, ex vivo monocyte function and circulating inflammatory proteins, although we found a tendency for lower high sensitive CRP levels after magnesium supplementation compared to placebo. In conclusion, magnesium supplementation modulates the function of CD4+ and CD8+ T-cells in people with type 2 diabetes and low serum magnesium levels.

Risk of Pre-Eclampsia in Women with Low Serum Ionized Magnesium

Background: There are many risk factors of development of preeclampsia among the pregnant women. Objective: The purpose of the present study has set out to assess the relationship between preeclampsia and blood ionized magnesium levels.&#x0D; Methodology: This case-control study was performed in the Department of Obstetrics and Gynaecology, Dhaka Medical College and Hospital from January 2020 to December 2021 for a period of 2(two) years. Pregnant patients who showed preeclampsia were all the amounts of ionized magnesium in venous blood collected from patients with preeclampsia. Additionally, the magnesium levels of age-matched, healthy pregnant women were determined.&#x0D; Results: A total number of 100 pregant women included in this study of which 50 pregnant women were designated as case and the rest 50 pregnant women were control. It has found that serum levels of ionized magnesium were significantly decreased among preeclamptic cases (0.58 ± 0.06) as compared to normal pregnancies (0.72 ± 0.05) (p &lt; 0.001). Using a cut-off value of 0.7 mmol/l, the serum ionized magnesium level was divided into two groups and was compared between cases and controls. The risk of developing preeclampsia was more than 33 (95% CI = 10.9 – 102.1) times higher in pregnant women with serum magnesium level &lt; 0.7 mmol/L than those pregnant women with serum magnesium level 0.7 or &gt; 0.7 mmol/L.&#x0D; Conclusion: Low level of serum ionized magnesium is a risk factor of development of preeclampsia.
