Newborn foals are susceptible to life-threatening diseases. Therefore, it is important to identify markers that make it possible to predict the survival of these patients, and to initiate the appropriate treatment for each case. This study was conducte at the Foal Care Equine Perinatology Center located in Cajicá, Cundinamarca. The medical records of 106 foals admitted to hospitalization between September 2019 and December 2020 were reviewed and analyzed to assess the predictive value of blood gas and electrolyte parameters against the survival of hospitalized neonatal foals. Different statistical tests were used, such as the Kolmogorov Smirnov test, Mann-Whitney U test, binary logistic regression, chi-square tests, odds ratio, and receiver operator characteristic (ROC) curve analysis. It was observed that the most common acid-base disorder upon admission to hospitalization was metabolic acidosis (37/106), and the most frequent electrolyte imbalance was hypocalcemia (89/106). The variable most significantly related to survival was pH > 7.35 (p = 0.007; OR = 0.288; CI = 95%, 0.117-0.706). The risk factors associated with non-survival of the foals were pH < 7.35, lactate > 4.5, and glucose < 119.5 mg/dl. [ABSTRACT FROM AUTHOR]

Objective: To describe electrolyte and acid-base imbalances in patients with hyperglycemic crisis attended at emergency in a general hospital in Chiclayo. Methods: A case series of diabetic patients with hyperglycemic crisis that were followed for 3 hours. Clinical, demographic, blood gases, serum glucose and electrolytes were gathered from patient's charts. Results: 52 patients were evaluated; mean age was 55.1 ± 16.9 years and 29 (55.8%) were females. Mean time to diagnosis was 4.3 ± 5.4 months; 13 (25.0%) occurred at onset of diabetes and 4 (7.7%) died. The most common symptom was mental confusion in 14 (26,9%) of patients, 30 (57,7%) had acute renal failure. Hyponatremia in 26 (50.0%) patients and hypokalemia in 18 (34.6%) were the most common electrolyte abnormalities found. Metabolic acidosis was more frequently found in patients with ketoacidosis than in hyperosmolar coma (85.0 vs 15.0%; p<0.0001). Acute renal failure occurred in 76.7% among patients with ketoacidosis and in 23.3% of patients with hyperosmolar coma (p=0.74). Conclusions: the frequency and complications of diabetic ketoacidosis and of hyperosmolar coma as well as the electrolyte abnormalities differed from those reported in the literature.

Objectives: To determine the frequency of acid-base disorders and their association with prevalent diseases in patients admitted to the emergency department of a national hospital in Lima. Methods: Cross-sectional study with a sample size of 108 patients in whom the treating physician requested arterial blood gases determination. The sample was attained by saturation until reaching the targeted sample size. Results: The most common acid-base disorder was mixed metabolic acidosis (50%) co-existing in patients with acute or chronic renal dysfunction and shock, followed by respiratory alkalosis (26.2%) associated to respiratory and gastro-intestinal disorders. Conclusions: Mixed metabolic acidosis and respiratory alkalosis are the most frequent acid-base abnormalities observed in this setting, respiratory alkalosis is the most common single acid-base disorder found.

For the study samples of Rhodic Ferrasol soils was collected with different uses, low activity anthropic (Artemisa), I cultivate potato-sweet potato (Batabano), cane of sugar (Guira de Melena) and I fallow grass (Nazareno Educational Unit). She took for the analysis the horizon A with a depth 0-20 cm. The samples dried off to the air and they were sifted being used a sieve 2 mm, to subject them later on to the extraction of the humic acid. They were characterized by spectroscopic UV-sense and to FT-GO, as well as the properties acid-base of the humic acid (AH): content of group's functional acids, and constant of apparent acidity (pKa). The evidences opposing spectroscopic that the systems of use of the floor caused modifications in the structure of the AH that you/they possess that you/they are reflected regarding the functional groups and the condensation level. The properties acid-base evaluated in the AH were affected by the type of applied use, as consequence of the detected structural changes. The capacity buffer, the quantity of group's functional acids and the relative strength of these presented different values. The humicacid coming from the system of cane of sugar was those that presented the most unfavorable variations that can influence on the functions of it should carry out the matter organic humicacid in the soils.
