The adrenal gland is part of the endocrine system and produces hormones that are essential for survival. The adrenal cortex, the largest part of the adrenal gland, produces three major hormones. Glucocorticoids regulate metabolism of glucose, protein, and fat and allow the body to respond to stress by increasing blood glucose levels and cardiac output. Mineralocorticoids regulate fluid and electrolyte balance and help maintain blood pressure. Androgens are responsible for sexual differentiation in the fetus.Insufficient production of these hormones can occur for many reasons and can have a profound effect on the newborn. It is important for neonatal nurses to be familiar with signs and symptoms and appropriate treatment of adrenal insufficiency. This article explores causes, signs and symptoms, and treatment of adrenal insufficiency in the newborn.

Regulation and coordination of different body organs is important in multicellular organisms. Hormones and the nervous system participate in this synchronization. Hormones are the compounds and chemical messengers produced by cells, glands, or special tissues called the endocrine system and released into the bloodstream. In addition to the hormones, blood is consist of proteins, sugars, lipids, vitamins, etc. Blood sugar is glucose which produces energy in the body. Regular blood glucose levels vary at different ages and exceed 120-170 mg / dl. It is harmful and even fatal to increase or decrease it from the normal level, so the concentration of glucose dissolved in plasma was subject to tight regulation and various regulatory mechanisms were developed thereon. Hormones cortisol, glucagon, adrenaline, and glucocorticoids are the major regulators. These substances are tracked regularly to prevent blood glucose from rising and dropping. Insulin consists of hyperglycemia, as well as other hormones. The mechanism by which it affects the metabolism of the food (carbohydrates, lipids, proteins) prevents hypoglycemia in several respects.

Objective: Today, there are various non-invasive techniques available for the determination of blood glucose levels. In this study, the level of blood glucose was determined by developing a new device using near-infrared (NIR) wavelength, glass optical waveguide, and the phenomenon of evanescent waves. Materials and Methods: The body's interstitial fluid has made possible the development of new technology to measure the blood glucose. As a result of contacting the fingertip with the body of the borehole rod, where electromagnetic waves are reflected inside, evanescent waves penetrate from the borehole into the skin and are absorbed by the interstitial fluid. The electromagnetic wave rate absorption at the end of the borehole rod is investigated using a detection photodetector, and its relationship to the people's actual blood glucose level. Following precise optimization and design of the glucose monitoring device, a statistical population of 100 participants with a maximum blood glucose concentration of 200 mg/dL was chosen. Before measurements, participants put their index finger for 30 seconds on the device. Results: According to this experimental study, the values measured by the innovative device with Clark grid analysis were clinically acceptable in scales A and B. The Adjusted Coefficient of Determination of the data was estimated to be 0.9064. Conclusion: For future investigations, researchers are recommended to work with a larger statistical population and use error reduction trends to improve the accuracy and expand the range of measurements.

A large newborn infant with hemihypertrophy, omphalocele, hepatomegaly, left upper quadrant abdominal mass, and zoster-like skin rash had severe hypoglycemia at 4 hours of age. Serum immunoreactive insulin levels were markedly elevated. Hypoglycemia was not controlled by vigorous medical therapy but blood glucose levels returned toward normal following subtotal excision of the markedly hyperplastic pancreas at 24 days of age. At 4½ months of age, a right upper quadrant abdominal mass was noted and urinary adrenal steroid levels were elevated. The right adrenal gland was found to be markedly hyperplastic and it was removed; the left adrenal gland was slightly hyperplastic. Between the ages of 5 and 8 months the umbilical stump enlarged progressively forming a large pedunculated tumor which was removed. This patient presents an unusually severe example of Beckwith's syndrome with both prenatal and postnatal organ overgrowth, severe hypoglycemia and hyperinsulinism.

The artificial pancreas (AP) is a system intended to control blood glucose levels through automated insulin infusion, reducing the burden of subjects with type 1 diabetes to manage their condition. To increase patients’ safety, some systems limit the allowed amount of insulin active in the body, known as insulin-on-board (IOB). The safety auxiliary feedback element (SAFE) layer has been designed previously to avoid overreaction of the controller and thus avoiding hypoglycemia. In this work, a new method, so-called “dynamic rule-based algorithm,” is presented in order to adjust the limits of IOB in real time. The algorithm is an extension of a previously designed method which aimed to adjust the limits of IOB for a meal with 60 grams of carbohydrates (CHO). The proposed method is intended to be applied on hybrid AP systems during 24 h operation. It has been designed by combining two different strategies to set IOB limits for different situations: (1) fasting periods and (2) postprandial periods, regardless of the size of the meal. The UVa/Padova simulator is considered to assess the performance of the method, considering challenging scenarios. In silico results showed that the method is able to reduce the time spent in hypoglycemic range, improving patients’ safety, which reveals the feasibility of the approach to be included in different control algorithms.

<p><strong>INTRODUCTION: </strong>Perioperative hyperglycemia has been shown to be related to higher levels of morbidity and mortality in patients on cardiopulmonary bypass (CPB) undergoing coronary artery bypass grafting (CABG), both diabetic and non-diabetic. Blood electrolytes, like sodium, potassium, calcium, and chloride play a very important role in the normal functioning of the body and can lead to a variety of clinical disorders if they become deficient. A minimal number of studies have been conducted on the simultaneous perioperative changes in both blood glucose and electrolyte levels during CPB in Pakistan. Therefore, our aim is to record and compare the changes in blood glucose and electrolyte levels during CPB in diabetic and non-diabetic patients.</p><p><strong>MATERIALS &amp; METHODS: </strong>This was a prospective, observational study conducted on 200 patients who underwent CABG with CPB, from October 2014 to March 2015. The patients were recruited from the Cardiac Surgery Ward, Civil Hospital Karachi after they complied with the inclusion criteria. Repeated-measures analysis of variance (ANOVA) was used to compare the trend of the changes perioperatively for the two groups.</p><p><strong>RESULTS: </strong>There was no significant difference in changes in blood glucose between the two groups (<em>P</em> = 0.62). The only significant difference detected between the two groups was for PaCO<sub>2</sub> (<em>P</em> = 0.001). Besides, further analysis revealed insignificant group differences for the trend changes in other blood electrolytes (<em>P</em> &gt; 0.05).</p><p><strong>CONCLUSION: </strong>Our findings highlighted that there is no significant difference in blood electrolytes changes and the increase in blood glucose levels between diabetic and non-diabetic patients.</p>

Autophagy is an important cellular process involving the degradation of intracellular components. Its regulation is complex and while there are many methods available, there is currently no single effective way of detecting and monitoring autophagy. It has several cellular functions that are conserved throughout the body, as well as a variety of different physiological roles depending on the context of its occurrence in the body. Autophagy is also involved in the pathology of a wide range of diseases. Within the endocrine system, autophagy has both its traditional conserved functions and specific functions. In the endocrine glands, autophagy plays a critical role in controlling intracellular hormone levels. In peptide-secreting cells of glands such as the pituitary gland, crinophagy, a specific form of autophagy, targets the secretory granules to control the levels of stored hormone. In steroid-secreting cells of glands such as the testes and adrenal gland, autophagy targets the steroid-producing organelles. The dysregulation of autophagy in the endocrine glands leads to several different endocrine diseases such as diabetes and infertility. This review aims to clarify the known roles of autophagy in the physiology of the endocrine system, as well as in various endocrine diseases.

&lt;p&gt;Diabetes increases the blood glucose levels above those of healthy individuals and poorly controlled diabetes is associated to ketoacidosis. Different authors have shown evidences that diabetes is linked to a higher risk of developing infections in different parts of the body. Although the reasons why diabetes enhances infection episodes are not entirely clear, different undesired physiological responses under diabetic environments are pointed out as the main causes, for example, inflammatory reactions, poor vascularization, neutrophilic chemotaxis or phagocytosis. However, it has so far not been quantified how high concentrations of glucose and ketone bodies can affect the beginning of the infectious process, i.e. the formation of biofilms.&lt;/p&gt; &lt;p&gt;In this sense, this research will address how the presence of glucose and ketone bodies can alter the biofilm formation capacity of Staphylococcus aureus. The research will be carried out with six different diabetic conditions, including the individual action of both components (glucose and ketone bodies) and the combined action.&lt;/p&gt; &lt;p&gt;The main conclusion of this work is that any studied diabetic condition is able to increase the slime index of S. aureus with respect to control (bacteria grown without diabetic supplements), so the biofilm formation capacity of this bacterium would rise in diabetic people. In addition to the change that can be as high as 400% in glucose concentrations of 1.9 mg/ml, the clustering behavior among the bacteria is also modified at all condition differently.&lt;/p&gt;

Abstract Fetal liver (FL) contains hepatic stem cells, hematopietic stem cells, and mesenchymal stem cells, as well as pluripotent stem cells and very small embryonic-like stem cells. FL has thus been available as a source of stem cells for regenerative medicine. Our previous report suggested that combining FL cell transplantation with the transplantation of fetal thymus prevented tumor growth in tumor-bearing mice. Moreover, in animal models, intra bone marrow-bone marrow transplantation (IBM-BMT) has proven to be the best approach for allogenic BMT. We here propose that transplanting FL cells by IBM-BMT can improve immune functions in leptin receptor-deficient (db/db) mice. FL cells were collected from FLs of C57BL/6 mice at 16 days post coitum, and then transplanted by IBM-BMT to leptin receptor deficent mice, an animal model of type 2 diabetes with obesity. Our results showed that the body weight was significantly lowered in the treated db/db mice than in the sham-treated db/db mice. The plasma IL-6 level significantly decreased and adiponectin level significantly increased after the transplantation of FL cells. Blood glucose levels also significantly decreased although not to within the normal range. This is the first report that the transplantation of FL cells may improve immune function, resulting in increased adiponectin levels, and decreased body weight in db/db mice.

Hyperglycemia is a condition of increased blood glucose levels caused by insufficient insulin enzymes produced to control blood sugar levels in the body. This study aimed to determine the activity of ethanol-water, nhexane, and ethyl acetate extracts of Dioscorea alata L. in reducing blood  glucose levels in hyperglycemia modeled mice that were given intraperitoneal alloxan induction. 25 white rats were divided into 5 groups of test animals. Each group consists of 5 mice. The first group was given 0.5% sodium carboxymethylcellulose solution as a placebo, the second group was given 0.65 mg/kg BW glibenclamide as a positive comparison group, the third group was given the suspension of ethanol-water extract, the fourth group was given n-hexane extract, and the fifth group was given ethyl acetate extract at a dose of 140 mg/kg BW. The test preparation was orally given within 14 days of testing. The test was measured as the initial blood glucose levels of mice after alloxan induction and after giving the test preparation suspension. The results of the qualitative analysis illustrate that the water-ethanol extract can reduce blood glucose levels by 31.39%, n-hexane extract by 51.11%, and ethyl acetate extract by 50.77%. The results of quantitative analysis using One Way ANOVA method showed that the water-ethanol, n-hexane, and ethyl acetate extracts significantly decreased the blood glucose levels of mice. The best antidiabetic activity was ethyl acetate extract with a decrease in rat blood glucose levels by 169 mg/kg BW.
