RESUMO
INTRODUCTION: The development of temporomandibular disorders specifically emphasizes the biochemical changes occurring in the synovial fluid at different stages of temporomandibular joint disease. Research has indicated that inflammation may be a primary reason behind the pain and dysfunction in temporomandibular joint diseases. Since its clearance several years ago, MESNA (sodium 2-mercaptoethanesulfonate) has been used in various formulations as a mucolytic drug in the respiratory domain. It operates by disrupting the disulfide bonds present between polypeptide chains within mucus. MESNA exhibits minimal tissue distribution, with the material being swiftly and thoroughly eliminated via the kidneys. OBJECTIVES: To assess the efficacy of injecting MESNA directly into the Temporomandibular Joint to treat internal derangement. MATERIALS AND METHODS: A randomized clinical trial was conducted on sixty patients who exhibited non-responsiveness to conventional treatment and were diagnosed with TMJ anterior disc displacement with reduction. The patients were chosen from the outpatient clinic of the Oral and Maxillofacial Surgery Department at Tanta University Faculty of Dentistry. Two equal groups of patients were randomly assigned to each other. Group I (Mesna group) received intra-articular injection with MESNA solution. Group II (Standard group) received arthrocentesis with lactated ringer solution followed by injection of Hyaluronic Acid (HA). The data was gathered by functional examinations such as maximum interincisal opening (MIO) and clicking. A Visual Analogue Scale (VAS) assessed pain severity before and after treatments. RESULTS: Both MESNA and HA showed significant improvement up to six months of the follow-up compared to preoperative status, as evidenced by better mouth opening, lateral excursion, lower clicking, and reduced pain score in patients with TMDs. MESNA showed significant improvement during follow-up compared to HA. CONCLUSION: Compared to HA, MESNA showed a more noticeable improvement during the follow-up period.

INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) plays an indispensable role in treating pancreato-biliary diseases but carries a risk of post-ERCP pancreatitis (PEP). Despite advances in the prevention strategies, prevention of PEP remains imperfect, necessitating more refined hydration methods. This study investigates the effectiveness of lactated Ringer's solution versus plasma solution in preventing PEP. METHOD AND ANALYSIS: This multicentre, double-blind, randomised controlled trial, will be initiated by the investigator-sponsor, and conducted in three tertiary centres in South Korea. The aim of this study is to assess the effectiveness of hydration in preventing PEP in patients with naïve papillae. It will target patients with naïve papillae, focusing on those at medium to high risk of PEP. Patients aged ≤18 years and those with serious comorbidities, acute/chronic pancreatitis and various other medical conditions will be excluded. Eligible participants will be randomly assigned into two arms in equal numbers: (1) PEP prevention using lactated Ringer's solution and (2) PEP prevention using plasma solution. The primary outcome of this study will be the occurrence of PEP, and secondary outcomes will be additional risk factors and potential adverse events related to ERCP. With a total enrolment of 844 patients, the study will be able to detect significant differences between the intervention arms. ETHICS AND DISSEMINATION: Ethical approval is obtained from each institution (Asan Medical Centre, 2023-0382; Seoul National University Hospital, H-2302-05-1404; Samsung Medical Centre, SMC 2023-02-001-009). All participants provided informed consent following clear explanation of the study procedures. The results of the study will be disseminated in peer-reviewed journals and research conferences. TRIAL REGISTRATION NUMBER: NCT05832047. PROTOCOL VERSION: Ver 4.1 (2023).

INTRODUCTION: A mainstay in the acute management of diabetic ketoacidosis (DKA) is fluid resuscitation. Normal saline is recommended by the American Diabetes Association; however, it has been associated with hyperchloremic metabolic acidosis and acute kidney injury. Limited literature is available to determine the most appropriate crystalloid fluid to treat patients with DKA. OBJECTIVE: The purpose of this study was to compare lactated Ringer's (LR) to normal saline (NS) in the acute management of DKA. METHODS: This was a retrospective, multicenter single health system cohort study. The primary outcome was to evaluate the time to high anion gap metabolic acidosis (HAGMA) resolution using LR compared to NS. Secondary outcomes included the incidence of nongap metabolic acidosis, hyperchloremia, acute kidney injury, and new renal replacement therapy. Other secondary outcomes included insulin infusion duration and hospital and intensive care unit length of stay. The Cox proportional hazards model was used for the primary outcome. RESULTS: A total of 771 patient encounters were included. Lactated Ringer's was associated with faster time to HAGMA resolution compared to NS (adjusted hazard ratio 1.325; 95% confidence interval 1.121-1.566; p < 0.001). No difference was found in complications such as incidence of nongap metabolic acidosis, hyperchloremia, acute kidney injury, and new renal replacement therapy between the LR and NS groups. Additionally, there was no difference in insulin infusion duration and hospital or intensive care unit length of stay. CONCLUSION: Treatment with LR as the primary crystalloid for acute DKA management was associated with faster HAGMA resolution compared with NS. Similar incidence in complications and length of stay was observed between the two groups. The findings of this study add to the accumulating literature suggesting that balanced crystalloids may offer an advantage over NS for the treatment of patients with DKA.

OBJECTIVE: To describe and compare prothrombin time (PT), activated partial thromboplastin time (aPTT), thromboelastography (TEG), HCT, and platelet count measurements in a hemorrhage/over-resuscitation model. DESIGN: Randomized crossover study. SETTING: University teaching hospital. ANIMALS: Six cats. INTERVENTIONS: Anesthetized cats underwent 3 treatments at 2-month intervals. The treatments were as follows: NHR-no controlled hemorrhage and sham resuscitation; LRS-controlled hemorrhage and lactated Ringer's solution (LRS) for resuscitation; and Voluven-controlled hemorrhage and 6% tetrastarch 130/0.4 for resuscitation. The LRS and Voluven were administered at 60 and 20 mL/kg/h, respectively, for 120 minutes. Blood samples were drawn for PT, aPTT, TEG, HCT, and platelet count measurements at a healthy check (T - 7d), after controlled hemorrhage (T0), at 60 and 120 minutes of resuscitation (T60 and T120), and at 24 hours after completion of resuscitation (T24h). Data were analyzed using a general linear mixed model approach (significance was P < 0.05). MEASUREMENTS AND MAIN RESULTS: Total median blood loss (controlled hemorrhage and blood sampling from T0 to T120) at T120 was 11.4, 31.0, and 30.8 mL/kg for NHR, LRS, and Voluven, respectively. PT and aPTT during LRS and Voluven were prolonged at T60 and T120 compared to NHR (P < 0.001). On TEG, the reaction time, kinetic time, and alpha-angle were within reference intervals for cats at all time points in all treatments, while maximum amplitude was less than the reference interval (40 mm) at T0, T60, and T120 during Voluven and at T60 and T120 during LRS compared to NHR (both P < 0.001). The HCT and platelet count were significantly lower at T60 and T120 during LRS and Voluven compared to NHR (P < 0.001). CONCLUSIONS: Hypocoagulopathy was observed during hemorrhage and liberal fluid resuscitation. Prolongation of PT and aPPT and decreased clot strength may have been caused by hemodilution and platelet loss.

PURPOSE: Intraocular irrigating solution is extensively applied in cataract surgery. This paper explored the difference and relationship between optical coherence tomography (OCT) and optical quality analysis system (OQAS) parameters induced by compound electrolyte intraocular irrigating solution (CEIIS) or Ringer lactate (RL) solution during uncomplicated cataract surgery. METHODS: Totally 200 senior cataract patients were randomly divided into the CEIIS and RL groups (N = 100 patients/group). The anterior chamber was irrigated by CEIIS or RL during phacoemulsification. Patients were subdivided into diabetes mellitus (DM)+ and DM- groups. The central macular thickness (CMT), hyper reflective foci (HF), modulation transfer function cutoff frequency (MTF cutoff), Strehl ratio (SR), objective scatter index (OSI), and OQAS values (OVs) at 100%, 20%, and 9% contrast levels were measured preoperatively and 1 day and 1 week after operation using spectral-domain optical coherence tomography and OQAS II, respectively. Best-corrected visual acuity (BCVA) was assessed using the Snellen scale, followed by statistical analysis of its logarithm of the minimal angle of resolution. RESULTS: There were no significant differences in clinical characteristics between the CEIIS and RL groups. Both groups exhibited notably increased postoperative CMT, MTF cutoff, SR, OV at 100%, 20%, and 9% contrast levels, and reduced OSI, indicating CEIIS and RL improved postoperative visual quality. CEIIS surpassed RL solution in improving postoperative visual quality, decelerating the increase of macular HF numbers and CMT in DM+ patients and postoperative BCVA. There was no difference between CEIIS and RL in long-term vision improvement. CONCLUSION: CEIIS surpasses RL in postoperative visual recovery and retards increases of macular HF numbers and CMT in senior DM+ cataract patients.

OBJECTIVE: To determine the effectiveness of the different pharmacological agents in preventing post-ERCP acute pancreatitis. METHODS: We included clinical trials of pharmacological interventions for prophylaxis of acute post-ERCP pancreatitis. The event evaluated was acute pancreatitis. We conducted a search strategy in MEDLINE (OVID), EMBASE, and Cochrane Central Register of Controlled Trials from inception to nowadays. We reported the information in terms of relative risks (RR) with a 95% confidence interval. We assessed the heterogeneity using the I2 test. RESULTS: We included 84 studies for analysis (30,463 patients). The mean age was 59.3 years (SD ± 7.01). Heterogeneity between studies was low (I2 = 34.4%) with no inconsistencies (p = 0.2567). Post ERCP pancreatitis was less in prophylaxis with NSAIDs (RR 0.65 95% CI [0.52 to 0.80]), aggressive hydration with Lactate Ringer (RR 0.32 95% CI [0.12-0.86]), NSAIDs + isosorbide dinitrate (RR 0.28 95% CI [0.11-0.71]) and somatostatin and analogues (RR 0.54 [0.43 to 0.68]) compared with placebo. CONCLUSIONS: NSAIDs, the Combination of NSAIDs + isosorbide dinitrate, somatostatin and analogues, and aggressive hydration with lactate ringer are pharmacological strategies that can prevent post-ERCP pancreatitis when compared to placebo. More clinical trials are required to determine the effectiveness of these drugs.

The study was aimed to investigate the positive impact of bicarbonate Ringer's solution on postoperative outcomes in patients who underwent laparoscopic right hemihepatectomy. Patients in the two groups were infused with lactated Ringer's solution (LRS, n = 38) and the bicarbonate Ringer's solution (BRS, n = 38) at a rate of 5 ml·kg-1·h-1. The stroke volume was monitored and 200 ml of hydroxyethyl starch with 130/0.4 sodium chloride injection (Hes) of a bolus was given in the first 5-10 min. The main outcome was to test lactic acid (LAC) concentration before and after surgery. The concentrations of LAC in the LRS group were higher than in the BRS group at 2 h after operation began, at the end of the operation and 2 h after the operation. Overall, the parameters including pH, base excess (BE), HCO3-, aspartate transaminase (AST) and alanine transaminase (ALT) were improved. The values of bilirubin in the LRS group were higher and albumin were lower than in the BRS group at post-operation 1st and 2nd day (P<0.05). The time of prothrombin time (PT) and activated partial thromboplastin time (APTT) in the LRS group were longer than that in the BRS group at post-operation 1st and 2nd day (P<0.05). Likewise, the concentrations of Mg2+, Na+ and K+ also varied significantly. The length of hospital was reduced, and the incidence of premature ventricular contractions (P = 0.042) and total complications (P = 0.016) were lower in group BRS. TRIAL REGISTRATION: The study was registered at clinicalTrials.gov with the number ChiCTR2000038077 on 09/09/2020.

BACKGROUND: Current guidelines recommend normal saline (NS) for fluid resuscitation in the management of patients presenting with diabetic ketoacidosis (DKA). However, previous prospective studies have demonstrated improvement in patient-specific outcomes, including time to DKA resolution, when balanced crystalloid fluids are used. METHODS: We conducted a single institution, retrospective cohort study of adult patients admitted with DKA before and after a protocol change within our institution, which shifted the default resuscitative and maintenance fluid in our DKA management protocol from NS to lactated Ringer's solution (LR). The primary outcome was time from DKA clinical presentation until DKA resolution. The secondary outcome was time to discontinuation of DKA protocol insulin drip. RESULTS: Of 246 patients meeting inclusion criteria, 119 were in the NS group (preprotocol change, where NS was the default resuscitative fluid) and 127 to the LR group (postprotocol change, where LR was the default resuscitative fluid). Time to DKA resolution was significantly decreased in the LR group (mean = 17.1 hours; standard deviation [SD] = 11.0) relative to the NS group (mean = 20.6 hours; SD = 12.2; P = .02). Duration of DKA protocol insulin drip was shorter in the LR group (mean = 16.0 hours; SD = 8.7) compared with the NS group (mean = 21.4 hours; SD = 12.5; P < .001). CONCLUSIONS: In this retrospective cohort study, protocolized DKA intravenous fluid management with LR resulted in shorter time to resolution of DKA and reduced duration of DKA protocol insulin drip.

Reactive species are involved in various aspects of neoplastic diseases, including carcinogenesis, cancer-specific metabolism and therapeutics. Non-thermal plasma (NTP) can directly provide reactive species, by integrating atmospheric and interjacent molecules as substrates, to represent a handy strategy to load oxidative stress in situ. NTP causes apoptosis and/or ferroptosis specifically in cancer cells of various types. Plasma-activated Ringer's lactate (PAL) is another modality at the preclinical stage as cancer therapeutics, based on more stable reactive species. PAL specifically kills malignant mesothelioma (MM) cells, employing lysosomal ·NO as a switch from autophagy to ferroptosis. However, the entire molecular mechanisms have not been elucidated yet. Here we studied cytosolic iron regulations in MM and other cancer cells in response to PAL exposure. We discovered that cells with higher catalytic Fe(II) are more susceptible to PAL-induced ferroptosis. PAL caused a cytosolic catalytic Fe(II)-associated pathology through iron chaperones, poly (rC)-binding proteins (PCBP)1/2, inducing a disturbance in glutathione-regulated iron homeostasis. PCBP1/NCOA4-mediated ferritinophagy started at a later phase, further increasing cytosolic catalytic Fe(II), ending in ferroptosis. In contrast, PCBP2 after PAL exposure contributed to iron loading to mitochondria, leading to mitochondrial dysfunction. Therapeutic effect of PAL was successfully applied to an orthotopic MM xenograft model in mice. In conclusion, PAL can selectively sensitize MM cells to ferroptosis by remodeling cytoplasmic iron homeostasis, where glutathione and PCBPs play distinct roles, resulting in lethal ferritinophagy and mitochondrial dysfunction. Our findings indicate the clinical application of PAL as a ferroptosis-inducer and the potential of PCBPs as novel targets in cancer therapeutics.

BACKGROUND: Volume replacement with crystalloid fluid is the conventional treatment of hemorrhage. We challenged whether a standardized amount of 5% or 20% albumin could be a viable option to maintain the blood volume during surgery associated with major hemorrhage. Therefore, the aim of this study was to quantify and compare the plasma volume expansion properties of 5% albumin, 20% albumin, and Ringer-lactate, when infused during major surgery. METHODS: In this single-center randomized controlled trial, fluid replacement therapy to combat hypovolemia during the hemorrhagic phase of cystectomy was randomly allocated in 42 patients to receive either 5% albumin (12 mL/kg) or 20% albumin (3 mL/kg) over 30 min at the beginning of the hemorrhagic phase, both completed by a Ringer-lactate replacing blood loss in a 1:1 ratio, or Ringer-lactate alone to replace blood loss in a 3:1 ratio. Measurements of blood hemoglobin over 5 h were used to estimate the effectiveness of each fluid to expand the blood volume using the following regression equation: blood loss plus blood volume expansion = factor + volume of infused albumin + volume of infused Ringer-lactate. RESULTS: The median hemorrhage was 848 mL [IQR: 615-1145]. The regression equation showed that the Ringer-lactate solution expanded the plasma volume by 0.18 times the infused volume while the corresponding power of 5% and 20% albumin was 0.74 and 2.09, respectively. The Ringer-lactate only fluid program resulted in slight hypovolemia (mean, - 313 mL). The 5% and 20% albumin programs were more effective in filling the vascular system; this was evidenced by blood volume changes of only + 63 mL and - 44 mL, respectively, by long-lasting plasma volume expansion with median half time of 5.5 h and 4.8 h, respectively, and by an increase in the central venous pressure. CONCLUSION: The power to expand the plasma volume was 4 and almost 12 times greater for 5% albumin and 20% albumin than for Ringer-lactate, and the effect was sustained over 5 h. The clinical efficacy of albumin during major hemorrhage was quite similar to previous studies with no hemorrhage.

OBJECTIVES: Data driven strategies for acute pancreatitis (AP) in pediatrics are limited; adult data suggests lactated ringers (LR) compared to normal saline (NS) resulted in favorable outcomes, but has not been studied in pediatrics. Our objective was to evaluate the efficacy of LR during the first 48 h of an AP episode compared with NS. STUDY DESIGN: A multisite randomized controlled clinical trial, from 2015 to 2020 (Clinical Trials.gov NCT03242473). Patients were randomized to exclusively LR or NS for the first 48 h. Primary outcomes were serial C-reactive protein (CRP) values. Secondary outcomes included other lab values, time to feeds, length of stay (LOS), systemic inflammatory response syndrome (SIRS) development, and progression to severe AP (SAP). RESULTS: We studied 76 patients (38 LR, 38 NS). CRP at 24 and 48 h were not significantly different between LR or NS group. Additionally, there were no differences in trends of BUN, amylase, lipase, SIRS status, or SAP development between the LR and NS group at 24 and 48 h. A higher proportion of LR patients (32%, 12/38) were discharged before 48 h compared to NS (13%, 5/38). The LR group had a significantly higher rate of discharge within the first 72 h compared to the NS group (p = 0.02). CONCLUSION: The use of LR was associated with a faster rate of discharge during the intervention period and in the first 72 h, but no other differences compared to NS. This reduction in length of hospitalization has significant implications for patients and healthcare costs.

ABSTRACT: Background: Normal saline solution (NSS) and Ringer's acetate solution (RAS) are commonly given to critically ill patients as a fundamental fluid therapy. However, the effect of RAS and NSS on sepsis patient outcomes remains unknown. Methods: We conducted a single-center prospective open-label parallel controlled trial to enroll adult patients (>18 years old) diagnosed with sepsis. Participants received either RAS or NSS for intravenous infusion for 5 days. The primary outcome was the incidence of major adverse kidney events within 28 days (MAKE28). Secondary outcomes included 30-/90-day mortality, acute kidney injury, and hyperchloremia. The patients were then reclassified as NSS-only, RAS-only, and RAS + NSS groups according to the type of fluid they had received before enrollment. Thereafter, a secondary post hoc analysis was performed. Results: Two hundred fifty-five septic patients were screened, and 143 patients (51.0% in RAS group and 49.0% in NSS group) were enrolled in the study. Each group received a median of 2 L of fluid administration during five interventional days. Of the patients, 39.3% had received 500 mL (500-1,000 mL) of balanced salt solutions (BSSs) before intensive care unit (ICU) admission. There was no statistical difference among the RAS and NSS group on the primary outcome MAKE28 in the initial analysis (23.3% vs. 20.0%; OR, 1.2 [0.6 to 2.2]; P = 0.69). MAKE28 was observed in 23.3% of RAS-only versus 27.3% of NSS-only group patients (0.82 [0.35-1.94], P = 0.65) in the secondary post hoc analysis. The patients in the NSS-only group had a longer invasive mechanical ventilation days and a trend toward the accumulation of serum chloride. Conclusion: This study observed no statistically significant difference on MAKE28 and secondary outcomes among sepsis patients receiving RAS and NSS. However, it is unclear whether the large amount of fluid resuscitation before ICU admission and carrier NSS narrowed the difference between BSSs and NSSs.

INTRODUCTION: There is insufficient evidence regarding the optimal regimen for ascites replacement after living donor liver transplantation (LT) and its effectiveness. The aim of this study is to evaluate the impact of replacing postoperative ascites after LT with albumin on time to first flatus during recovery with early ambulation and incidence of acute kidney injury (AKI). METHODS: Adult patients who underwent elective living donor LT at Seoul National University Hospital from 2019 to 2021 were randomly assigned to either the albumin group or lactated Ringer's group, based on the ascites replacement regimen. Replacement of postoperative ascites was performed for all patients every 4 h after LT until the patient was transferred to the general ward. Seventy percent of ascites drained during the previous 4 h was replaced over the next 4 h with continuous infusion of fluids with a prescribed regimen according to the assigned group. In the albumin group, 30% of a total of 70% of drained ascites was replaced with 5% albumin solution, and remnant 40% was replaced with lactated Ringer's solution. In the lactated Ringer's group, 70% of drained ascites was replaced with only lactated Ringer's solution. The primary outcome was the time to first flatus from the end of the LT and the secondary outcome was the incidence of AKI for up to postoperative day 7. RESULTS: Among the 157 patients who were screened for eligibility, 72 patients were enrolled. The mean age was 63 ± 8.2 years, and 73.0 % (46/63) were male. Time to first flatus was similar between the two groups (66.7 ± 24.1 h vs. 68.5 ± 25.6 h, p = .778). The albumin group showed a higher glomerular filtration rate and lower incidence of AKI until postoperative day 7, compared to the lactated Ringer's group. CONCLUSIONS: Using lactated Ringer's solution alone for replacement of ascites after living donor LT did not reduce the time to first flatus and was associated with an increased risk of AKI. Further research on the optimal ascites replacement regimen and the target serum albumin level which should be corrected after LT is required.

OBJECTIVES: The use of del Nido cardioplegia has been increasing in popularity for adult cardiac surgery. However, the base solution, Plasma-Lyte A, is not always available in many countries. This prospective randomized controlled trial evaluated myocardial preservation and clinical outcomes when using lactated Ringer's solution (LRS) compared to Plasma-Lyte A as a base solution for del Nido cardioplegia. METHODS: Adult patients undergoing first-time elective cardiac surgery for acquired heart disease, including isolated coronary artery bypass grafting, isolated valve surgery, combined valve surgery or concomitant coronary artery bypass grafting and valve surgery were randomized to receive either LRS (n = 100) or Plasma-Lyte A (n = 100). RESULTS: There were no significant differences between the 2 groups in terms of age, comorbidities, Society of Thoracic Surgeons risk score and type of procedures. The primary outcome, postoperative troponin-T at 24 h, was similar in both groups (0.482 vs 0.524 ng/ml; P = 0.464). Other cardiac markers were also similar at all time points. The LRS group had a lower pH (7.228 vs 7.246; P = 0.005) and higher calcium levels (0.908 vs 0.358 mmol/l; P < 0.001) in the delivered cardioplegia, but there were no significant differences in clinical outcomes, such as ventricular fibrillation, left ventricular ejection fraction, inotrope/vasopressor requirement, intra-aortic balloon pump support, intensive care unit stay, hospital stay, atrial fibrillation, red cell transfusion and complications. CONCLUSIONS: The results suggest that LRS can be used as an alternative to Plasma-Lyte A as the base solution for del Nido cardioplegia, with similar myocardial preservation and clinical outcomes.

PURPOSE: To compare the effects of a fortified balanced salt solution (fSS) and Ringer's lactate solution (Ringer) on anterior chamber (AC) inflammation in patients undergoing phacoemulsification. SETTING: Tianjin Medical University Eye Hospital, Tianjin, China. DESIGN: Prospective masked controlled trial. METHODS: 80 patients (40 patients with regular cataract and 40 cataract patients with diabetes mellitus [DM]) were randomized to receive either fSS (n = 40) or Ringer's solution (n = 40). Anterior-segment optical coherence tomography was used to evaluate AC cells and flare. Transepithelial electrical resistance (TEER) and zonula occludens-1 (ZO-1) immunofluorescence were used for tight junction examination. Monocytic leukemia cell line (Tohoku Hospital Pediatrics-1 [THP-1]) transmigration assay was performed to observe the effects of the 2 perfusates on the inflammatory response in vitro. RESULTS: In patients with regular cataracts, postoperative AC cells and flare on the 1st and 7th days were not significantly different between the Ringer and fSS groups. However, in cataract patients with DM, AC cells were higher in the Ringer group than in the fSS group ( P = .003) on postoperative day 1. The AC flare was also significantly higher in the Ringer group than in the fSS group ( P < .0001). No significant differences between the groups were observed on day 7. Compared with Ringer, fSS increased the TEER value and ZO-1 content and reduced the adhesion of THP-1 cells. CONCLUSIONS: The results of this study indicated that early postoperative AC inflammation is more severe in patients with cataracts and DM. In addition, fSS attenuates inflammation by protecting the blood-aqueous barrier and inhibiting the exudation of inflammatory cells.

BACKGROUND: Due to limited research on the effectiveness and safety of intravenous (IV) fluids administered during labor, there are no guidelines available. Thus, this meta-analysis aims to evaluate efficacy of IV Ringer's lactate during labor as compared to usual care. METHODS: Six databases were searched for the randomized controlled trials (RCTs) comparing the effects of IV Ringer's lactate at 125 mL/h or 250 mL/hr during labor in nulliparous women at term as compared to usual care, and the search results were imported to Covidence for screening of the articles. All the concerned outcomes were pooled as risk ratios (RR) or mean difference (MD) with 95% CI in the meta-analysis models using RevMan 5.4. RESULTS: Pooled data from 7 RCTs with 967 nulliparous women showed that the active stage of labor duration (MD -32.16 with 95% CI [40.43 to -23.90], p < 0.00001), need of oxytocin augmentation (RR 0.72 with 95% CI [0.54 to 0.96], p = 0.03) and incidence of prolonged labor (RR 0.57 with 95% CI [0.34 to 0.95], p = 0.03) was significantly lower with IV Ringer's lactate. However, the total duration of labor (p = 0.23), duration of second stage of labor (p = 0.31) and cesarean section rate (p = 0.070) did not differ between the two groups. The test for subgroup analysis based on infusion rate was significant (p = 0.01) for the active stage of labor. CONCLUSION: IV Ringer's lactate reduced the duration of active labor, the need for oxytocin augmentation and the prolonged labor incidence. However, it did not differ in effect on immediate neonatal health but was found to have more potential for reducing maternal vomiting as compared to usual care with unrestricted oral intake. Further research is needed to explore its effects in the larger and more diverse populations and with different IV fluids for evidence-based guidelines.

BACKGROUND: Current diabetic ketoacidosis (DKA) treatment guidelines recommend using normal saline (NS); however, NS may delay DKA resolution by causing more hyperchloremic metabolic acidosis compared with balanced crystalloids. This study's objective was to determine the feasibility of a future multicentred randomised controlled trial (RCT) comparing intravenous Ringer's lactate (RL) with NS in managing ED patients with DKA. METHODS: We conducted a parallel-arm, triple-blind, pilot RCT of adults (≥18 years) with DKA at a Canadian academic tertiary care ED. The primary feasibility outcome was recruitment rate (target ≥41.3% of eligible participants over the 1-year study period); the primary efficacy outcome was time elapsed from ED presentation to DKA resolution. The superiority margin for a clinically significant difference was chosen to be a 40% time reduction to DKA resolution. We also assessed the need to break allocation concealment and loss to follow-up. Patients with clinical suspicion for DKA were screened for inclusion and enrolled patients were randomised 1:1 to receive RL or NS. Patients, clinicians and outcome assessors were blinded to allocation. RESULTS: We enrolled 52 (25 RL, 27 NS) of 60 eligible patients (86.7%), exceeding our target recruitment rate. There were more patients in the NS group with type 1 diabetes, and more patients in the RL group had an admission co-diagnosis in addition to DKA. For the 44 participants with confirmed laboratory evidence of resolution, median (IQR) time to DKA resolution for RL versus NS was 15.7 (10.4-18.8) and 12.7 (7.9-19.2) hours, respectively. There were no cases where blinding was broken, and there was no loss to follow-up. CONCLUSIONS: This pilot trial demonstrated our protocol's feasibility by exceeding our target recruitment rate. Our results may be used to inform future multicentre trials to compare the safety and efficacy of RL and NS in managing DKA in the ED. TRIAL REGISTRATION NUMBER: NCT04926740.

This study aimed to explore the impact of different pH values of resuscitation fluid on traumatic hemorrhagic shock (THS), focusing on their effects on glycocalyx and inflammation. A rat model of THS was induced by hemorrhage from a left femur fracture, while an oxygen-glucose deprivation/reoxygenation (OGD/R)-induced HULEC-5a cell model was considered as an in vitro THS model. The lung tissue pathology and glycocalyx structure were assessed through hematoxylin-eosin (H&E) staining and transmission electron microscope examination. The levels of glycocalyx-related factors and inflammation-related factors were determined by enzyme-linked immunosorbent assay (ELISA). The expression of glycocalyx-related proteins, cell junction-related proteins, and proteins involved in the PI3K/Akt/NF-κB signaling pathway was analyzed by western blot. The results showed that both sodium bicarbonate Ringer's solution (BRS) and lactate Ringer's solution (LRS) were effective in restoring mean arterial pressure and heart rate in THS rats. However, LRS has a stronger impact on promoting inflammation and damaging the glycocalyx compared with BRS. In OGD/R-induced HULEC-5a cells, a pH of 7.4 and 6.5 increased inflammation and disrupted the glycocalyx, while a pH of 8.1 had no significant effect on inflammation or glycocalyx. Furthermore, the PI3K/Akt/NF-κB signaling pathway was activated by fluid resuscitation and different pH values. However, the activating effect of BRS and pH 8.1 on the PI3K/Akt/NF-κB signaling pathway was milder compared with LRS and pH6.5. In conclusion, an alkaline recovery environment was more beneficial for the treatment of THS.
