Effectiveness of ORSL® Variants as an Adjuvant along with Standard-of-care Treatment in the Restoration of Oral Fluid, Electrolytes, and Energy in Patients with Fever and/or General Weakness in Indian Patients in an Outpatient Setting.

BACKGROUND: Dehydration due to reduced intake or increased losses including insensible losses in patients with acute nondiarrheal diseases may lead to fluid, electrolytes, and energy (FEE) deficits. The impact of oral FEE supplementation adjuvant to standard of care (SOC) treatment on recovery in patients with acute nondiarrheal diseases is yet to be evaluated. AIM: To determine the effectiveness of ORSL® variants (ORSL® Apple Drink and ORSL® PLUS Orange Drink), fruit juice-based electrolyte drinks as an adjuvant along with SOC in the restoration of oral FEE in patients with acute nondiarrheal disease with fever and/or general weakness who attended an outpatient department (OPD). MATERIALS AND METHODS: This was a prospective, interventional, open-label, multicenter, real-world, study conducted at eight sites across India. Patients with fever and/or general weakness due to an acute nondiarrheal illness were given either ORSL® Apple Drink or ORSL® PLUS Orange Drink as an adjuvant along with SOC treatment per physician's discretion. The primary endpoint of the study was to assess improvement from baseline in energy or hydration levels after ORSL® variants consumption at 6, 24, and 48 hours measured by a new aided recovery scale (ARS). Secondary endpoints were to assess the improvement in energy and hydration levels at 20, 40, and 60 minutes, as well as energy levels and hydration levels at 20, 40, and 60 minutes, 6, 24, and 48 hours after the consumption of ORSL® Apple Drink or ORSL® PLUS Orange Drink. The patient's consumption of ORSL® variants and treatment experience, physician's experience of recommending ORSL® variants, and product safety were evaluated. RESULTS: In total, 612 patients were enrolled with mean age 38.3 years, of whom 62.9% were male. The mean baseline level of energy and hydration was 1.59 (range 1.0-2.0) on ARS. Statistically significant (p < 0.0001) improvements were observed in energy or hydration 6 hours after first consumption of ORSL formulations. Furthermore, improvement was observed from 40 minutes, and in levels of energy, hydration, and both energy and hydration from 60 minutes. Patients and physicians reported a positive experience with ORSL® variants. CONCLUSION: ORSL® Apple Drink and ORSL® PLUS Orange Drink are clinically proven to provide hydration and/or energy to patients with fever and/or general weakness.

Protein-based oral rehydration solutions for patients with an ileostomy: A randomised, double-blinded crossover study.

BACKGROUND & AIM: Patients with an ileostomy are at increased risk of dehydration and sodium depletion. Treatments recommended may include oral rehydration solutions (ORS). We aimed to investigate if protein type or protein hydrolysation affects absorption from iso-osmolar ORS in patients with an ileostomy. METHODS: This was a randomised, double-blinded, active comparator-controlled 3 × 3 crossover intervention study. We developed three protein-based ORS with whey protein isolate, caseinate or whey protein hydrolysate. The solutions contained 40-48 g protein/L, 34-45 mmol sodium/L and had an osmolality of 248-270 mOsm/kg. The patients ingested 500 mL/d. The study consisted of three 4-week periods with a >2-week washout between each intervention. The primary outcome was wet-weight ileostomy output. Ileostomy output and urine were collected for a 24-h period before and after each intervention. Additionally, blood sampling, dietary records, muscle-strength tests, bioimpedance analyses, questionnaires and psychometric tests were conducted. RESULTS: We included 14 patients, of whom 13 completed at least one intervention. Ten patients completed all three interventions. Wet-weight ileostomy output did not change following either of the three interventions and did not differ between interventions (p = 0.38). A cluster of statistically significant improvements related to absorption was observed following the intake of whey protein isolate ORS, including decreased faecal losses of energy (-365 kJ/d, 95% confidence interval (CI), -643 to -87, p = 0.012), potassium (-7.8 mmol/L, 95%CI, -12.0 to -3.6, p = 0.001), magnesium (-4.0 mmol/L, 95%CI, -7.4 to -0.7, p = 0.020), improved plasma aldosterone (-4674 pmol/L 95%CI, -8536 to -812, p = 0.019), estimated glomerular filtration rate (eGFR) (2.8 mL/min/1.73 m2, 95%CI, 0.3 to 5.4, p = 0.03) and CO2 (1.7 mmol/L 95%CI, 0.1 to 3.3, p = 0.04). CONCLUSION: Ingestion of 500 mL/d of iso-osmolar solutions containing either whey protein isolate, caseinate or whey protein hydrolysate for four weeks resulted in unchanged and comparable ileostomy outputs in patients with an ileostomy. Following whey protein isolate ORS, we observed discrete improvements in a series of absorption proxies in both faeces and blood, indicating increased absorption. The protein-based ORS were safe and well-tolerated. Treatments should be tailored to each patient, and future studies are warranted to explore treatment-effect heterogeneity and whether different compositions or doses of ORS can improve absorption and nutritional status in patients with an ileostomy. GOV STUDY IDENTIFIER: NCT04141826.

Patient adherence to an oral rehydration solution intervention to prevent dehydration following ileostomy creation: A qualitative study.

BACKGROUND: Patients undergoing surgery for ileostomy creation frequently experience postoperative dehydration and subsequent renal injury. The use of oral rehydration solutions (ORS) has been shown to prevent dehydration, but compliance may be variable. METHODS: Semi-structured qualitative interviews were conducted with 17 patients who received a postoperative hydration kit and dehydration education to assess barriers and facilitators to compliance with ORS kit instructions. RESULTS: Qualitative analysis revealed five themes affecting patient adherence to the ORS intervention: (1) patient's perception of the effectiveness of the ORS solution, (2) existing co-morbidities, (3) kit quality and taste of the ORS product, (4) quality of the dehydration education, and (5) social support. CONCLUSIONS: Given that patient adherence can greatly affect the success of an ORS intervention, the design of future ORS interventions should emphasize the educational component, the "patient friendliness" of the ORS kit, and ways that social supports can be leveraged to increase adherence.

Iterative assessment of a sports rehydration beverage containing a novel amino acid formula on water uptake kinetics.

PURPOSE: Rapid gastric emptying and intestinal absorption of beverages is essential for rapid rehydration, and certain amino acids (AA) may augment fluid delivery. Three sugar-free beverages, containing differing AA concentrations (AA + PZ), were assessed for fluid absorption kinetics against commercial sugar-free (PZ, GZ) and carbohydrate-containing (GTQ) beverages. METHODS: Healthy individuals (n = 15-17 per study) completed three randomised trials. Three beverages (550-600 mL) were ingested in each study (Study 1: AA + PZ [17.51 g/L AA], PZ, GZ; Study 2: AA + PZ [6.96 g/L AA], PZ, GZ; Study 3: AA + PZ [3.48 g/L AA], PZ, GTQ), containing 3.000 g deuterium oxide (D2O). Blood samples were collected pre-, 2-min, 5-min, and every 5-min until 60-min post-ingestion to quantify maximal D2O enrichment (Cmax), time Cmax occurred (Tmax) and area under the curve (AUC). RESULTS: Study 1: AUC (AA + PZ: 15,184 ± 3532 δ‰ vs. VSMOW; PZ: 17,328 ± 3153 δ‰ vs. VSMOW; GZ: 17,749 ± 4204 δ‰ vs. VSMOW; P ≤ 0.006) and Tmax (P ≤ 0.005) were lower for AA + PZ vs. PZ/GZ. Study 2: D2O enrichment characteristics were not different amongst beverages (P ≥ 0.338). Study 3: Cmax (AA + PZ: 440 ± 94 δ‰ vs. VSMOW; PZ: 429 ± 83 δ‰ vs. VSMOW; GTQ: 398 ± 81 δ‰ vs. VSMOW) was greater (P = 0.046) for AA + PZ than GTQ, with no other differences (P ≥ 0.106). CONCLUSION: The addition of small amounts of AA (3.48 g/L) to a sugar-free beverage increased fluid delivery to the circulation compared to a carbohydrate-based beverage, but greater amounts (17.51 g/L) delayed delivery.

Osmoprotection in Salvia hispanica L seeds under water stress attenuators / Osmoproteção em sementes de Salvia hispanica L sob atenuadores do estresse hídrico

Salvia hispanica cultivation is recent in Brazil and occurs in the off-season, when there is lower water availability in the soil. Water deficit is one of the abiotic factors that most limit germination for compromising the sequence of metabolic events that culminate with seedling emergence. Several attenuating substances have been used to mitigate the effects resulting from this stress and give higher tolerance to the species. Thus, the objective of this study was to evaluate the action of different agents as water stress attenuators in the germination and accumulation of organic compounds in S. hispanica seedlings. The treatments consisted of pre-soaking the seeds for 4 hours in salicylic acid (1 mM.L-¹), gibberellic acid (0.4 mM.L-¹), distilled water and control treatment (without soaking). The seeds were germinated at osmotic potentials of 0.0, -0.1, -0.2, -0.3 and -0.4 MPa, using PEG 6000 as an osmotic agent. The variables germination percentage, germination speed index, shoot and primary root lengths, total dry mass, proline, total soluble sugars and total free amino acids were analyzed. Salicylic acid and gibberellic acid led to the best results among the attenuators tested, increasing germination, length, dry mass and biochemical components of S. hispanica seedlings under water deficit. Therefore, salicylic and gibberellic acids are efficient in mitigating water stress in S. hispanica seeds up to the potential of -0.4 MPa.

O cultivo da Salvia hispanica é recente no Brasil e se dá no período de entressafra, quando há menor disponibilidade hídrica no solo. O déficit hídrico é um dos fatores abióticos que mais limitam a germinação por comprometer a sequência de eventos metabólicos que culminam com a emergência da plântula. Diversas substâncias atenuadoras têm sido empregadas com a finalidade de mitigar os efeitos resultantes desse estresse e conferir maior tolerância às espécies. Desse modo, objetivou-se avaliar a ação de diferentes agentes como atenuadores do estresse hídrico na germinação e acúmulo de compostos orgânicos em plântulas de S. hispanica. Os tratamentos consistiram na pré-embebição das sementes durante 4 horas em ácido salicílico (1 mM.L-¹), ácido giberélico (0,4 mM.L-¹), água destilada e o tratamento controle (sem embebição). As sementes foram germinadas sob os potenciais osmóticos 0,0, -0,1, -0,2, -0,3 e -0,4 MPa, utilizando PEG 6000 como agente osmótico. Analisaram-se as variáveis porcentagem de germinação, índice de velocidade de germinação, comprimento da parte aérea e da raiz primária, massa seca total, prolina, açúcares solúveis totais e aminoácidos livres totais. O ácido salicílico e o ácido giberélico apresentaram os melhores resultados, dentre os atenuadores testados, incrementando a germinação, o comprimento, a massa seca e os componentes bioquímicos de plântulas de S. hispanica sob déficit hídrico. Logo, os ácidos salicílico e giberélico são eficientes na mitigação do estresse hídrico em sementes de S. hispanica até o potencial -0,4 MPa.

Sensory Perception of an Oral Rehydration Solution during Exercise in the Heat.

Prolonged exercise in the heat elicits a number of physiological changes as glycogen stores are low and water and electrolytes are lost through sweat. However, it is unclear whether these changes provoke an increase in liking of saltiness and, therefore, palatability of an oral rehydration solution (ORS). Twenty-seven recreationally active participants (n = 13 males; n = 14 females) completed sensory analysis of an ORS, a traditional sports drink (TS), and a flavored water placebo (PL) at rest and during 60 min (3 × 20-min bouts) of cycling exercise at 70% age-predicted maximum heart rate (HRmax) at 35.3 ± 1.4 °C and 41 ± 6% relative humidity. Before and after every 20 min of exercise, drinks were rated (using 20-mL beverage samples) based on liking of sweetness, liking of saltiness, thirst-quenching ability, and overall liking on a nine-point hedonic scale. Hydration status was assessed by changes in semi-nude body mass, saliva osmolality (SOsm), and saliva total protein concentration (SPC). After 60 min of exercise, participants lost 1.36 ± 0.39% (mean ± SD) of body mass and there were increases in SOsm and SPC. At all time points, liking of sweetness, saltiness, thirst-quenching ability, and overall liking was higher for the TS and PL compared to the ORS (p < 0.05). However, the saltiness liking and thirst-quenching ability of the ORS increased after 60 min of exercise compared to before exercise (p < 0.05). There was also a change in predictors of overall liking with pre-exercise ratings mostly determined by liking of sweetness, saltiness, and thirst-quenching ability (p < 0.001), whereas only liking of saltiness predicted overall liking post-exercise (R2 = 0.751; p < 0.001). There appears to be a hedonic shift during exercise in which the perception of saltiness becomes the most important predictor of overall liking. This finding supports the potential use of an ORS as a valuable means of hydration during the latter stages of prolonged and/or intense exercise in the heat.

Carbohydrate hastens hypervolemia achieved through ingestion of aqueous sodium solution in resting euhydrated humans.

PURPOSE: Ingesting beverages containing a high concentration of sodium under euhydrated conditions induces hypervolemia. Because carbohydrate can enhance interstitial fluid absorption via the sodium-glucose cotransporter and insulin-dependent renal sodium reabsorption, adding carbohydrate to high-sodium beverages may augment the hypervolemic response. METHODS: To test this hypothesis, we had nine healthy young males ingest 1087 ± 82 mL (16-17 mL per kg body weight) of water or aqueous solution containing 0.7% NaCl, 0.7% NaCl + 6% dextrin, 0.9% NaCl, or 0.9% NaCl + 6% dextrin under euhydrated conditions. Each drink was divided into six equal volumes and ingested at 10-min intervals. During each trial, participants remained resting for 150 min. Measurements were made at baseline and every 30 min thereafter. RESULTS: Plasma osmolality decreased with water ingestion (P ≤ 0.023), which increased urine volume such that there was no elevation in plasma volume from baseline (P ≥ 0.059). The reduction in plasma osmolality did not occur with ingestion of solution containing 0.7% or 0.9% NaCl (P ≥ 0.051). Consequently, urine volume was 176-288 mL smaller than after water ingestion and resulted in plasma volume expansion at 60 min and later times (P ≤ 0.042). In addition, net fluid balance was 211-329 mL greater than after water ingestion (P ≤ 0.028). Adding 6% dextrin to 0.7% or 0.9% NaCl solution resulted in plasma volume expansion within as little as 30 min (P ≤ 0.026), though the magnitudes of the increases in plasma volume were unaffected (P ≥ 0.148). CONCLUSION: Dextrin mediates an earlier hypervolemic response associated with ingestion of high-sodium solution in resting euhydrated young men. (247/250 words).

Can an amino acid mixture alleviate gastrointestinal symptoms in neuroendocrine tumor patients?

BACKGROUND: Neuroendocrine tumors, although relatively rare in incidence, are now the second most prevalent gastrointestinal neoplasm owing to indolent disease biology. A small but significant sub-group of neuroendocrine tumor patients suffer from diarrhea. This is usually secondary to carcinoid syndrome but can also be a result of short gut syndrome, bile acid excess or iatrogenic etiologies. Recently, an amino acid based oral rehydration solution (enterade® Advanced Oncology Formula) was found to have anti-diarrheal properties in preclinical models. METHODS: A retrospective chart review of all NET patients treated with enterade® AO was performed after IRB approval. RESULTS: Ninety-eight NET patients who had received enterade® AO at our clinic from May 2017 through June 2019 were included. Patients (N = 49 of 98) with follow up data on bowel movements (BMs) were included for final analysis. Eighty-four percent of patients (41/49) had fewer BMs after taking enterade® AO and 66% (27/41) reported more than 50% reduction in BM frequency. The mean number of daily BMs was 6.6 (range, 3-20) at baseline before initiation of therapy, while the mean number of BMs at 1 week time point post enterade® AO was 2.9 (range, 0-11). CONCLUSIONS: Our retrospective observations are encouraging and support prospective validation with appropriate controls in NET patients. This is first published report of the potential anti-diarrheal activity of enterade® AO in NET patients.

Effect of oral rehydration solution versus spring water intake during exercise in the heat on muscle cramp susceptibility of young men.

BACKGROUND: Muscle cramp is a painful, involuntary muscle contraction, and that occurs during or following exercise is referred to as exercise-associated muscle cramp (EAMC). The causes of EAMC are likely to be multifactorial, but dehydration and electrolytes deficits are considered to be factors. This study tested the hypothesis that post-exercise muscle cramp susceptibility would be increased with spring water ingestion, but reduced with oral rehydration solution (ORS) ingestion during exercise. METHODS: Ten men performed downhill running (DHR) in the heat (35-36 °C) for 40-60 min to reduce 1.5-2% of their body mass in two conditions (spring water vs ORS) in a cross-over design. The body mass was measured at 20 min and every 10 min thereafter during DHR, and 30 min post-DHR. The participants ingested either spring water or ORS for the body mass loss in each period. The two conditions were counter-balanced among the participants and separated by a week. Calf muscle cramp susceptibility was assessed by a threshold frequency (TF) of an electrical train stimulation to induce cramp before, immediately after, 30 and 65 min post-DHR. Blood samples were taken before, immediately after and 65 min after DHR to measure serum sodium, potassium, magnesium and chroride concentrations, hematocrit (Hct), hemoglobin (Hb), and serum osmolarity. Changes in these varaibles over time were compared between conditions by two-way repeated measures of analysis of variance. RESULTS: The average (±SD) baseline TF (25.6 ± 0.7 Hz) was the same between conditions. TF decreased 3.8 ± 2.7 to 4.5 ± 1.7 Hz from the baseline value immediately to 65 min post-DHR for the spring water condition, but increased 6.5 ± 4.9 to 13.6 ± 6.0 Hz in the same time period for the ORS condition (P < 0.05). Hct and Hb did not change significantly (P > 0.05) for both conditions, but osmolarity decreased (P < 0.05) only for the spring water condition. Serum sodium and chloride concentrations decreased (< 2%) at immediately post-DHR for the spring water condition only (P < 0.05). CONCLUSIONS: These results suggest that ORS intake during exercise decreased muscle cramp susceptibility. It was concluded that ingesting ORS appeared to be effective for preventing EAMC.

Efficacy of Ingesting an Oral Rehydration Solution after Exercise on Fluid Balance and Endurance Performance.

This study investigated the efficacy of ingesting an oral rehydration solution (DD) that has a high electrolyte concentration after exercise on fluid balance and cycling performance in comparison with a sports drink (SD) and water (WA). Nine healthy males aged 24 ± 2 years (mean ± SD), with peak oxygen uptake (VO2 peak) 55 ± 6 mL·kg-1·min-1 completed three experimental trials in a randomised manner ingesting WA, SD (carbohydrates: 62 g·L-1, sodium: 31 ± 3 mmol·L-1) or DD (carbohydrates: 33 g·L-1, sodium: 60 ± 3 mmol·L-1). On all trials, fluid was ingested during 75 min cycling at 65% VO2 peak (temperature: 30.4 ± 0.3 °C, relative humidity: 76 ± 1%, simulated wind speed: 8.0 ± 0.6 m·s-1) and during 2 h of recovery (temperature: 23.0 ± 1.0 °C, relative humidity: 67 ± 2%), with the total volume equivalent to 150% of sweat loss during the ride. A 45 min pre-load cycling time trial at a 65% VO2 peak followed by a 20 km time trial was conducted after a further 3 h of recovery. Fluid retention was higher with DD (30 ± 15%) than WA (-4 ± 19%; p < 0.001) and SD (10 ± 15%; p = 0.002). Mean ratings of palatability were similar among drinks (WA: 4.25 ± 2.60; SD: 5.61 ± 1.79; DD: 5.40 ± 1.58; p = 0.33). Although time trial performance was similar across all three trials (WA: 2365 ± 321 s; SD: 2252 ± 174 s; DD: 2268 ± 184 s; p = 0.65), the completion time was faster in eight participants with SD and seven participants with DD than with WA. Comparing SD with DD, completion time was reduced in five participants and increased in four participants. DD was more effective at restoring the fluid deficit during recovery from exercise than SD and WA without compromising the drink's palatability with increased sodium concentration. Most individuals demonstrated better endurance exercise time trial performance with DD and SD than with WA.

Oral rehydration solution coverage in under 5 children with diarrhea: a tri-country, subnational, cross-sectional comparative analysis of two demographic health surveys cycles.

BACKGROUND: More than 3 million children under 5 years in developing countries die from dehydration due to diarrhea, a preventable and treatable disease. We conducted a comparative analysis of two Demographic Health Survey (DHS) cycles to examine changes in ORS coverage in Zimbabwe, Zambia and Malawi. These surveys are cross-sectional conducted on a representative sample of the non-institutionalized individuals. METHODS: The sample is drawn using a stratified two-stage cluster sampling design with census enumeration areas, typically, selected first as primary sampling units (PSUs) and then a fixed number of households from each PSU. We examined national and sub-regional prevalence of ORS use during a recent episode of diarrhea (within 2 weeks of survey) using DHSs for 2007-2010 (1st Period), and 2013-2016 (2nd Period). Weighted proportions of ORS were obtained and multivariable- design-adjusted logistic regression analysis was used to obtain Odds Ratios (aORs) and 95% confidence intervals (CIs) and weighted proportions of ORS coverage. RESULTS: Crude ORS coverage increased from 21.0% (95% CI: 17.4-24.9) in 1st Period to 40.5% (36.5-44.6) in 2nd Period in Zimbabwe; increased from 60.8% (56.1-65.3) to 64.7% (61.8-67.5) in Zambia; and decreased from 72.3% (68.4-75.9) to 64.6% (60.9-68.1) in Malawi. The rates of change in coverage among provinces in Zimbabwe ranged from 10.3% over the three cycles (approximately 10 years) in Midlands to 44.2% in Matabeleland South; in Zambia from - 9.5% in Eastern Province to 24.4% in Luapula; and in Malawi from - 16.5% in the Northern Province to - 3.2% in Southern Province. The aORs for ORS use was 3.95(2.66-5.86) for Zimbabwe, 2.83 (2.35-3.40) for Zambia, and, 0.71(0.59-0.87) for Malawi. CONCLUSION: ORS coverage increased in Zimbabwe, stagnated in Zambia, but declined in Malawi. Monitoring national and province-level trends of ORS use illuminates geographic inequalities and helps identify priority areas for targeting resource allocation.. Provision of safe drinking-water, adequate sanitation and hygiene will help reduce the causes and the incidence of diarrhea. Health policies to strengthen access to appropriate treatments such as vaccines for rotavirus and cholera and promoting use of ORS to reduce the burden of diarrhea should be developed and implemented.

Subcutaneous Versus Intravenous Rehydration in Hospitalized Older Adults: A Meta-Analysis.

Subcutaneous rehydration is an optional infusion route in hospitalized older adults. This meta-analysis sought to compare the effectiveness of subcutaneous versus intravenous (IV) fluid administration to reverse mild-to-moderate dehydration in hospitalized older adults. A literature search was performed. No restrictions were imposed regarding language. Three randomized clinical trials conducted with patients 60 years of age or older treated with subcutaneous or IV rehydration were included, with a total sample size of 197 patients. Controlled quasi-randomized and crossover trials were excluded. The primary end point was reversal of dehydration. Secondary end points were patient satisfaction and frequency of adverse events (eg, cellulitis, edema, phlebitis, erythema, hyponatremia, and pain). Both treatments were effective in rehydrating the patients within 48 hours, with no statistically significant difference between the groups. Subcutaneous fluid administration effectively reversed dehydration while protecting against phlebitis. Since the quality of evidence was considerably low, further multicenter randomized clinical trials of efficient methodological quality should be conducted to consolidate the body of evidence.

Effect of different hydration doses on renal function in patients with primary osteoporosis treated with zoledronic acid: A hospital-based retrospective cohort study.

The objective was to investigate the association of different hydration doses and its effect on renal function in patients with primary osteoporosis treated with zoledronic acid.The subjects with primary osteoporosis treated with zoledronic acid at the First Affiliated Hospital of Chongqing Medical University, China, from January 2015 to December 2018 were included in this study. The subjects were classified according to different hydration doses. Renal function indexes before and after treatment were collected and adverse reactions recorded to analyze the changes in renal function associated with different hydration doses.The choice of the hydration dose treated with zoledronic acid deserves attention. The lower hydration dose is, the greater impact on renal function can be caused.

Strong community-based health systems and national governance predict improvement in coverage of oral rehydration solution (ORS): a multilevel longitudinal model.

Diarrheal disease remains a leading cause of child death globally, especially in low and middle-income countries. Use of oral rehydration solution (ORS) for treatment of diarrhea in children, a very cost-effective intervention, remains below 50% in many countries. Here we use a multi-level longitudinal model to reveal important predictors of ORS use at the national level. The findings suggest that increasing government effectiveness along with increased implementation and affordability of community-based health programs can lead to substantial increases in ORS use. Key informant interviews with national health leaders in countries that significantly improved ORS coverage support these quantitative findings.

Abomasal emptying rate of diarrhoeic and healthy suckling calves fed with oral rehydration solutions.

The aim of the study was to determine the abomasal emptying rate (AER) of calves suffering from naturally occurring diarrhoea compared with that of healthy calves. Furthermore, the effects of an oral rehydration solution (ORS) mixed into milk replacer on the AER were determined. Acetaminophen absorption test (APAT) was performed to estimate the AER. Sixty Holstein-Frisian calves (age < 14 days) were included in the study and divided into groups as follows: healthy calves (H; n = 16), healthy calves fed with ORS (HORS; n = 14), diarrhoeic calves (D; n = 15) and diarrhoeic calves fed with ORS (DORS; n = 15). For the APAT, the calves were fed 2 L of milk replacer containing 50 mg acetaminophen (AP)/kg body weight. Venous blood samples were collected before and after milk replacer and AP intake in 30-60 min intervals for 12 hr. During the APAT, no significant differences in median maximum acetaminophen concentration (Cmax ) were observed among all groups. Time to reach maximum acetaminophen concentration (Tmax ) in DORS (median 390 min, 25/75 quartiles: 300/480 min) was significantly higher compared with that in H (median: 270 min 25/75 quartiles: 210/315 min) and HORS (median: 300 min (25/75 quartiles: 240/360 min). Non-linear regression revealed that the calculated abomasal half-life (AP t1/2 ) tended to be delayed in DORS (median: 652 min, 25/75 quartiles: 445/795 min, p = .10). The area under the AP curve values (AUC) from 0 to 120 min and 0 to 240 min of the observation period were significantly higher in H than D and DORS. In conclusion, significant differences in the AER indices reflected delayed abomasal emptying in diarrhoeic calves. Furthermore, the hypertonic ORS tended to have an additive delaying impact on the AER, which needs attention for the feeding management of diarrhoeic calves.

Balanced Crystalloids Versus Saline in Critically Ill Adults: A Systematic Review and Meta-analysis.

Background: The optimal resuscitative fluid remains controversial. Objective: To assess the association between crystalloid fluid and outcomes in critically ill adults. Methods: Cumulative Index to Nursing and Allied Health Literature, Scopus, PubMed, and Cochrane Central Register for Controlled Trials were searched from inception through July 2019. Cohort studies and randomized trials of critically ill adults provided predominantly nonperioperative fluid resuscitation with balanced crystalloids or 0.9% sodium chloride (saline) were included. Results: Thirteen studies (n = 30 950) were included. Balanced crystalloids demonstrated lower hospital or 28-/30-day mortality (risk ratio [RR] = 0.86; 95% CI = 0.75-0.99; I2 = 82%) overall, in observational studies (RR = 0.64; 95% CI = 0.41-0.99; I2 = 63%), and approached significance in randomized trials (RR = 0.94; 95% CI = 0.88-1.02; I2 = 0%). New acute kidney injury occurred less frequently with balanced crystalloids (RR = 0.91; 95% CI = 0.85-0.98; I2 = 0%), though progression to renal replacement therapy was similar (RR = 0.91; 95% CI = 0.79-1.04; I2 = 38%). In the sepsis cohort, odds of hospital or 28-/30-day mortality were similar, but the odds of major adverse kidney events occurring in the first 30 days were less with balanced crystalloids than saline (OR = 0.78; 95% CI = 0.66-0.91; I2 = 42%). Conclusion and Relevance: Resuscitation with balanced crystalloids demonstrated lower hospital or 28-/30-day mortality compared with saline in critically ill adults but not specifically those with sepsis. Balanced crystalloids should be provided preferentially to saline in most critically ill adult patients.

The Use of Probiotic with ORS and ORS Only in Children with Acute Diarrhea.

OBJECTIVE: To compare the mean number of stools per day in children treated with combination of probiotic (lactobacillus rhamnosus) with ORS and ORS only in acute diarrhea. STUDY DESIGN: Randomised control trial. PLACE AND DURATION OF STUDY: Department of Pediatric Medicine, PNS Shifa Hospital, from February to July, 2017. METHODOLOGY: A total of 80 children with acute watery diarrhea were randomly divided into two groups. Forty patients in first group were given probiotic with ORS and 40 patients in second group (control) were given ORS only. All children were monitored from 0 day (inclusion day) to next 5 days. Demographic data was collected regarding age, gender, weight and frequency of loose stools. Dehydration status was also assessed at the time of admission by the attending physician. Data was collected through a structured proforma. RESULTS: The average age of the children was 24.3 ±18.65 months. There were 47 (58.8%) males and 33 (41.3%) females. Mean number of stools was significantly low in those patients who were treated with combination of probiotic (lactobacillus rhamnosus) with ORS than those who were treated with ORS only in acute diarrhea (3.25 ±1.13 vs. 4.13 ±0.79; p<0.001). CONCLUSION: Probiotics are found to be significantly more effective in reducing the stool frequency in acute diarrhea.
