Comparison of the Efficacy of Postoperative Pain Relief in Ultrasound Guided Fascia Illiaca Compartment Block versus Epidural Block on Quality of Recovery (QOR-15) in Patients Undergoing Femoral Surgery

Background: The occurrence of femoral fractures is quite high. The quality of life gets affected to a large extent due to pain and post-operative delirium. Various regional block techniques like Fascia illiaca compartment block, lumbar epidural analgesia, femoral nerve block, etc. have been described for femoral fractures. In this study, we compared the efficacy of post-operative pain relief FICB and Epidural block on quality of recovery (QOR-15) in patients undergoing femoral surgery. Methods: This study included 40 patients wherein 20 patients were given FICB and 20 patients were given Epidural block. The patients were followed up for post-operative pain relief, Quality of Recovery, occurrence of delirium, disability and fraility. Results: Quality of recovery QOR-15 was similar for both the groups preoperatively as well as at 24 hour and 48 hours post-operatively. Additionally, there was no difference in the time taken to administer the block, postoperative VAS score on movement and rest, requirement of additional analgesia and opioid consumption. Moreover, there were no significant differences in WHO disability assessment, modified frailty score, prevalence of delirium, mortality, morbidity and side effects of techniques. However, the total duration of hospital stay (in days) was found to be significantly more in the epidural group as compared with the FICB group (5.75±1.61 vs 4.75±1.16; P=0.38). Conclusion: Ultrasound guided fascia iliaca compartment block is a tangible alternative to epidural block in patients undergoing femoral fracture repair.

Predictors of acute kidney injury after percutaneous nephrolithotomy in adult patients: prospective observational study.

To assess the frequency and the predictive factors of Acute Kidney injury (AKI) in patients undergoing percutaneous nephrolithotomy (PNL). A prospective observational work. Demographic, preoperative laboratory data, stone characteristics, and intraoperative and postoperative data were gathered. Perioperative AKI had been defined as an elevation in serum creatinine by ≥ 0.3 mg/dl within 48h, or ≥ 1.5 times baseline, or urine volume less than 0.5ml/ kg/hour for 6hours. A multivariate logistic regression analysis was performed to determine the predictive factors of AKI. ROC curves were utilized to determine the cutoff values of the risk variables. P-values were deemed statistically significant when they were less than 0.05. A total of 418 participants had been involved. The frequency of AKI was 13.9, and 17.2% of patients with AKI developed CKD. The risk factors were age > 46.5 years, smoking, BMI > 28.5 kg/m2, hypertension, diabetes, utilization of angiotensin-converting enzyme inhibitors (ACEI), haemoglobin < 10.8 gm/dl, baseline creatinine > 1.41 mg/dl, eGFR < 65.2 ml/min./1.73 m2, serum uric acid > 5.2 mg/dl, stone volume > 1748 mm3, large tract size, long operative time, and intra-operative bleeding. Patients with AKI had a notably extended duration of hospitalization (3.2 days ± 0.45 vs 2.1 ± 0.42, p < 0.001). Perioperative AKI occurred in 13.9% of individuals undergoing PNL. Identification and optimization of the risk factors and meticulous technique during PNL procedures should be attempted to decrease the risk of AKI.

Is night emergency laparoscopy a high-risk surgery?

Introduction: Although laparoscopy has become the gold standard for many abdominal emergency pathologies, emergency nighttime laparoscopic surgery is considered high-risk for several reasons, particularly due to limited resources in the operating room during nighttime hours. The primary objective of our study is to evaluate the feasibility and safety of nighttime laparoscopy in the management of non-traumatic acute abdomen. Materials and Methods: Descriptive and prospective, evaluative study conducted between February 2018 and October 2021. Our study included 337 patients undergoing laparoscopic surgery for non-traumatic acute abdominal emergencies. Results: Among the 337 patients, we operated on 211 patients (62.6%) outside of regular working hours (between 4:00 PM and 8:00 AM), of which 189 patients (56.10%) were operated on from 4:00 PM to 12:00 AM, and 22 patients (6.2%) from 12:00 AM to 8:00 AM. The mean operative time was 52.09 ± 24.14 minutes. Perioperative difficulties related to the operated pathology were encountered in 21 cases (9.95%). The overall mean hospital stay was 1 day (range: 7 hours - 4 days). We compared nighttime laparoscopy with daytime laparoscopy and found an advantage in favor of nighttime laparoscopy in reducing hospitalization duration (p value 0.003). Conclusion: Nighttime laparoscopy is feasible and safe.

Outcomes from Early Experience with Laparoscopic Inguinal Hernia Repair Versus Open Technique

Objectives: This study aimed to evaluate the outcomes of laparoscopic inguinal hernia repair (LIHR) regarding postoperative pain, recurrence rates, duration of hospital stay and other postoperative outcomes within the context of a tertiary care teaching hospital in South India, and the initial experience of laparoscopic repairs. The current consensus in the literature often suggests LIHR as superior to open inguinal hernia repair (OIHR). Methods: This single-centre, retrospective, observational study was conducted at the Jawaharlal Institute of Postgraduate Education and Research, Puducherry, India, from January 2011 to September 2020. All patients who underwent elective OIHR and LIHR were included. Data on the patients demographics, comorbidities, hernia type, mesh characteristics, surgery duration, hospital stay and immediate postoperative complications were collected and analysed. Results: A total of 2,690 OIHR and 158 LIHR cases were identified. The demographic profiles, hospital stay and complication rates were similar in both groups. However, surgical site infection was present exclusively in the OIHR group (3.55% versus 0.0%; P &lt;0.05). The timeline for returning to normal activities was statistically shorter for the LIHR group (6 versus 8 days; P &lt;0.05). The most frequent immediate complication in the LIHR group was subcutaneous emphysema (6.54% versus 0.0%; P &lt;0.05). Recurrence (9.23% versus 3.61%; P = 0.09) and chronic pain (41.53% versus 13.55%; P &lt;0.05) were higher in the LIHR group. Conclusion: Lower recurrence and chronic pain rates were observed with OIHR in the initial experience with LIHR in the hospital. However, LIHR had significant advantages concerning faster patient recovery and lower rates of surgical site infections. While the results contribute an interesting deviation from the standard narrative, they should be interpreted within the context of a learning curve associated with the early experience of the research team with LIHR.

The mind matters: Psychological factors influence subjective outcomes following unicompartmental knee arthroplasty-A prospective study.

This study aimed to investigate how psychological factors, including pain catastrophizing (PC), anxiety and depression affect preoperative and postoperative subjective outcomes in patients undergoing unicompartmental knee arthroplasty (UKA). A prospective comparative study was performed among 150 patients undergoing medial or lateral UKA for isolated unicompartmental osteoarthritis. Patients were categorized based on their preoperative PC and Hospital Anxiety and Depression Scale, stratifying them into groups with PC, anxiety or depression, and those without these psychological factors. Patient-reported outcomes, including the Knee Injury and Osteoarthritis Outcome Score-Physical function Short form (KOOS-PS), 5-level EQ5D Visual Analogue Scale (EQ5D-VAS), Forgotten Joint Score (FJS) and Numeric Rating Scale for pain (NRS-pain) were compared between groups preoperatively and at 6-, 12-, and 24-month follow-up. At 24 months, PC patients had inferior outcomes in KOOS-PS (66.9 ± 16.5 vs. 77.6 ± 14.7, p = .008), EQ5D-VAS (63.5 ± 19.9 vs. 78.9 ± 20.1, p = .003) and FJS (73.7 ± 14.3 vs. 84.6 ± 13.8, p = .003). Anxiety was associated with inferior KOOS-PS (65.4 ± 15.2 vs. 78.2 ± 14.5, p = <.001), EQ5D-VAS (64.2 ± 23.2 vs. 79.3 ± 19.4, p = .002), FJS (75.7 ± 16.8 vs. 84.6 ± 13.4, p = .008) and NRS-pain (27.4 ± 24.6 vs. 13.7 ± 19.3, p = .023) at 24 months. Depression consistently resulted in inferior outcomes in KOOS-PS, EQ5D-VAS, FJS and NRS-pain across all follow-up assessments (p = <.05). Additionally, patients with anxiety and depression experienced longer length of hospital stay compared to those without these psychological factors (anxiety: 2.3 ± 2.3 vs. 0.8 ± 0.8 days, p = .006; depression: 2.3 ± 2.4 vs. 0.8 ± 0.8 days, p = .017). Preoperative PC, anxiety and depression are associated with inferior subjective outcomes both prior to and following UKA. Among these factors, depression seemed to exert the most substantial adverse impact on outcomes following UKA. Patients with anxiety and depression had an extended duration of hospitalization lasting over twice as long as patients without these psychological factors. It seems that inferior outcomes primarily stem from the suboptimal preoperative condition rather than an inherent inability to benefit from UKA. Level II, prospective study.

Laparoscopic surgery for endometrial cancer is oncologically safe and improves hospital stay duration: a retrospective single-center study over a 16-year period.

To investigate changes in surgical procedures and patient outcomes of patients diagnosed with endometrial cancer (EC) at a German university hospital between 1998 and 2014. A monocentric, retrospective review was conducted to identify patients diagnosed and treated with EC during the aforementioned period at the Department of Gynecology and Obstetrics at the University Hospital Kiel, Germany. 303 patients were identified. Patient demographics, risk factors, histological subtypes and stages of EC remained consistent over time. The most common surgical procedure was total abdominal hysterectomy (TAH) (81.9%). In 2011, the institution carried out its first total laparoscopic hysterectomy (TLH) for EC, resulting in a significant increase in laparoscopic surgical procedures (2011-2014: N=70; TAH 44.2%; TLH 51.4%). Although the total number of lymph node stagings remained consistent over time, there was a significant increase in the performance of simultaneous pelvic and para-aortic lymphonodectomy (LNE) compared to pelvic LNE alone (2.6 in 2001-2005 vs. 18.0% in 2011-2014, p≤0.001). The duration of hospital stays significantly decreased over time, with a mean of 20.9days in the first and 8.5days in the last period. When comparing surgical procedures, TLHs resulted in significantly shorter postoperative stays with an average of 6.58 vs. 13.92days for TAH. The surgical procedure performed did not affect 5-year overall survival rates in this study (84.9% for TAH and 85.3% for TLH, p=0.85). Our retrospective single-center study demonstrates that laparoscopic surgery for endometrial cancer is oncologically safe and shortens hospital stays.

Monocyte Anisocytosis Changes in Patients after Major Burn Injuries.

The recovery of patients after severe burns is a long and complex process. Recently, genomic analysis of white blood cells from burn and trauma patients revealed excessive and prolonged innate immune activation in patients with complicated outcomes. However, translating this knowledge into practical biomarkers has not been possible yet. Although several biomarkers for monitoring burn patients have been proposed, their ability to accurately distinguish between inflammation stemming from initial tissue destruction, infections, and organ failure complications is limited. Here, we focused on monocytes, critical innate immune cells in the response to burn injured tissues. We measured the monocyte anisocytosis (quantified as monocyte distribution width, MDW, a recently emerged marker of sepsis) throughout the recovery of patients from the time of burn injury until the end of the hospital stay. We observed that MDW increases in patients during the first week after major burns. Among the patients with major burns who survive, MDW starts decreasing in the second week and normalizes by the end of the hospital stay. The duration of hospital stay appears to be proportional to how fast MDW decreases during the second week after the injury. We also found that MDW decreases significantly in most patients after excision and debridement surgeries but not after allo- and auto-graft surgeries. Moreover, high MDW values correlated with a higher rate of positive microbiology blood culture samples and respiratory infections. These findings underscore the importance of monitoring MDW as a potential biomarker for the risk of complications during burn patient recovery.

Deciphering the microbial landscape of lower respiratory tract infections: insights from metagenomics and machine learning

BackgroundLower respiratory tract infections represent prevalent ailments. Nonetheless, current comprehension of the microbial ecosystems within the lower respiratory tract remains incomplete and necessitates further comprehensive assessment. Leveraging the advancements in metagenomic next-generation sequencing (mNGS) technology alongside the emergence of machine learning, it is now viable to compare the attributes of lower respiratory tract microbial communities among patients across diverse age groups, diseases, and infection types.MethodWe collected bronchoalveolar lavage fluid samples from 138 patients diagnosed with lower respiratory tract infections and conducted mNGS to characterize the lung microbiota. Employing various machine learning algorithms, we investigated the correlation of key bacteria in patients with concurrent bronchiectasis and developed a predictive model for hospitalization duration based on these identified key bacteria.ResultWe observed variations in microbial communities across different age groups, diseases, and infection types. In the elderly group, Pseudomonas aeruginosa exhibited the highest relative abundance, followed by Corynebacterium striatum and Acinetobacter baumannii. Methylobacterium and Prevotella emerged as the dominant genera at the genus level in the younger group, while Mycobacterium tuberculosis and Haemophilus influenzae were prevalent species. Within the bronchiectasis group, dominant bacteria included Pseudomonas aeruginosa, Haemophilus influenzae, and Klebsiella pneumoniae. Significant differences in the presence of Pseudomonas phage JBD93 were noted between the bronchiectasis group and the control group. In the group with concomitant fungal infections, the most abundant genera were Acinetobacter and Pseudomonas, with Acinetobacter baumannii and Pseudomonas aeruginosa as the predominant species. Notable differences were observed in the presence of Human gammaherpesvirus 4, Human betaherpesvirus 5, Candida albicans, Aspergillus oryzae, and Aspergillus fumigatus between the group with concomitant fungal infections and the bacterial group. Machine learning algorithms were utilized to select bacteria and clinical indicators associated with hospitalization duration, confirming the excellent performance of bacteria in predicting hospitalization time.ConclusionOur study provided a comprehensive description of the microbial characteristics among patients with lower respiratory tract infections, offering insights from various perspectives. Additionally, we investigated the advanced predictive capability of microbial community features in determining the hospitalization duration of these patients.

#2317 Did acute kidney injury confer greater mortality in COVID-19 hospitalized patients? A Portuguese hospital experience in the third COVID wave

Abstract Background and Aims The outbreak of coronavirus disease 2019 (COVID-19) pandemic, which originated in December 2019, had a huge impact on healthcare worldwide. Numerous studies have reported alterations in kidney function among hospitalized patients with COVID-19, such as hematuria, proteinuria, and acute kidney injury (AKI). Histopathology exams in autopsies have identified various potential causes for the presence of AKI in these patients, with reports linking AKI to unfavorable outcomes across multiple countries. However, additional data concerning hospitalized COVID patients in Portugal are essential to further understand this aspect. Method Retrospective cohort study enrolling adult patients, who attended the Emergency Department and recorded positive polymerase chain reaction (PCR) results for SARS-CoV-2 from January 1 to January 31, 2021. AKI was diagnosed using the Kidney Disease Improving Global Outcome (KDIGO) classification based on serum creatinine (sCr) criteria and using a background creatinine available in the patient record. We performed an analysis of incidence, lethality, and possible risk factors of AKI in COVID-19 patients. Results The study encompassed a cohort of 239 patients, of whom 62 (25.94%) received a diagnosis of Acute Kidney Injury (AKI) based on KDIGO criteria. Within this subgroup, the average age was 77.65 years (±12.07), with a total of 29 male patients (46.78%). Notably, 30 deaths (48.39%) occurred during the hospital stay in this group. Regarding the AKI classification, 39 patients (62.9%) were classified as KDIGO-AKI stage 1, 14 patients (22.58%) as stage 2, and 9 patients (14.52%) as stage 3. Regarding the timing of the diagnosis of AKI, 54 (87%) occurred in the moment of admission, 7 patients (11.3%) were diagnosed within the first 48 hours and a solitary case (1.6%) was diagnosed after 7 days of hospitalization. In the non-AKI group, the mean age was 69.86 years (±15.95), and approximately 55% were male. Within this group, 49 deaths (27.7%) were recorded during hospitalization. Significantly higher mortality rates were observed in the AKI group, demonstrating a statistically significant difference (p &amp;lt; 0.01) and a relative risk of 1.75 or mortality during hospitalization for AKI patients. Furthermore, the duration of hospitalization was notably prolonged in the AKI group (p &amp;lt; 0.01), with a disparity of approximately three days. Individuals who developed AKI exhibited lower scores on the Barthel-dependence scale, indicative of higher dependence (p &amp;lt; 0.01), and were significantly older (p &amp;lt; 0.01) comparing with the ones that did not develop acute kidney injury. Additionally, it was remarkable that the leukocyte count at admission was more elevated in the AKI group (p = 0.03) compared to non-AKI patients with a difference of approximately 1.62×109/L. Conclusion Respiratory infections, including COVID-19, frequently lead to emergency department admissions and hospitalizations. This study validates an elevated prevalence of acute kidney injury (AKI) both at admission and during the hospital stay in such cases. The presence of AKI is linked to adverse outcomes, including mortality and extended hospital stays, underscoring the critical importance of promptly diagnosing AKI. Larger-scale studies are warranted in this field to enhance our understanding of this entity and therefore improve the outcomes related to this prevalent condition.

#1748 The burden of cardiorenal syndrome: epidemiological data and treatment: a one-center experience

Abstract Background and Aims Cardiorenal syndrome (CRS) is an entity combining cardiac and renal dysfunction in a bi-directional way. Six subtypes of CRS have been described, all of which are associated with high morbidity and mortality rates. CRS treatment—no matter the subtype—is until nowadays a field of investigation, aiming to the reduction of fluid overload and venous congestion. The primary endpoint of this study was to estimate the frequency of cardiorenal induced AKI compared to other AKI etiologies in hospitalized patients. We furthermore aimed to determine the burden of the therapeutic regimen in hospitalization duration and renal deterioration. Method This is a retrospective, quantitative analysis of hospitalized adult patients in General Hospital of Athens Hippokration suffering from AKI of various etiologies. No age or sex limitations were used for the purposes of this study. Results A total amount of 1163 patients were enrolled over the course of 18 months. 430 (36.9%) of these patients were hospitalized in the cardiologic department, suffering from either acute or chronic heart failure (66.5% of which were men) with a mean age of 74.4 ± 11.4 years. Mean creatinine level at hospital admission was 2.7 ± 2 mg/dl. Out of these patients, 33.9% were treated using diuretics alone, while 25.5% also needed hemodialysis. Mean number of days of hospitalization was 9.4 ± 5.8 days and 11 ± 8.8 days, while creatinine exit was 2.9 ± 1.5 mg/dl and 4.2 ± 3 mg/dl respectively. Conclusion Cardiorenal syndrome is a quite common cause of AKI in patients being hospitalized. In our study, patients that needed treatment with diuretics compared to those requiring a combination of diuretics and hemodialysis had less days of hospitalization and a better kidney function outcome.

#815 Maternal and fetal outcomes in kidney transplant recipients: a single-center observational study

Abstract Background and Aims Pregnancy poses a high risk for adverse maternal and fetal outcomes in kidney transplant recipients (KTRs), and data on long-term allograft functions compared to healthy population are still limited. Therefore, we aimed to conduct a comparative analysis of maternal and fetal outcomes in KTRs with age-matched non-transplanted controls. Method In this retrospective single-center study, KTRs who experienced at least one pregnancy after transplantation between 1984 and 2016 were evaluated (study group). In order to create an age-matched control group, healthy women who had one pregnancy each and received prenatal care were included. Maternal and fetal outcomes were gestational age, preterm birth, newborn mortality, admittance to neonatal intensive care unit (NICU), Apgar scores, birth weight, and obstetric complications (preeclampsia, peripartum hemorrhage, duration of maternal hospitalization) in all pregnancies, and composite kidney outcome of KTRs which was defined as progression to graft failure necessitating dialysis or re-transplantation or doubling of serum creatinine at the end of follow-up. Results In 53 KTRs, 68 pregnancies occurred. Mean age at birth was 31.6 ± 5.2 for KTRs and 30.5 ± 5.8 for controls (p = 0.288). Preeclampsia (29.4% vs. 2.9%, p &amp;lt; 0.001) and preterm birth (57.4% vs. 32.4%, p = 0.003) were significantly higher in KTRs. KTR pregnancies had lower mean birth weight (2354 ± 814 vs. 2856 ± 729 mg, p = 0.001) and longer durations of maternal hospitalization (3 vs. 2 days, p = 0.001), as well. However, neonatal mortality, admittance to NICU, and peripartum hemorrhage rates and Apgar scores were similar (Table 1). Baseline serum creatinine and eGFR levels of KTRs were 1 (0.8-1.2) mg/dl and 76.6 (59.9-91.5) ml/min/1.73 m2, respectively. Follow-up for a median of 105 months after the index birth showed higher serum creatinine levels at postpartum visits (p &amp;lt; 0.001) and last follow-up (p = 0.001) compared to baseline, with a tendency for increased proteinuria during pregnancies (Table 2). Six KTRs (11.3%) experienced composite kidney outcomes, including 5 patients with graft failure and 1 with doubling of serum creatinine. Conclusion KTRs exhibit comparable neonatal mortality and NICU rates but higher rates of preeclampsia and preterm birth. Notably, graft functions worsen significantly during postpartum follow-up.

#1874 Comparative analysis of rehabilitation outcomes in hospitalized hemodialysis vs. non-hemodialysis patients: a retrospective cohort study

Abstract Background and Aims The hospitalization rate of patients undergoing hemodialysis (HD) is high, due to complications related to renal failure and hemodialysis treatment. Therefore, it is crucial to provide rehabilitation for hospitalized HD patients to improve their activities of daily living (ADL) and physical functions, so as to enable them to be discharged home, resume outpatient dialysis, and avoid re-hospitalization. However, the effectiveness of rehabilitation to improve the ADL and physical functions may differ between hospitalized patients undergoing HD (HD patients) and hospitalized patients not undergoing HD (non-HD patients), depending on their pathological conditions and influence of the HD treatment. The aim of the present study was to compare the outcomes of rehabilitation between hospitalized HD patients and non-HD patients. Method This was a retrospective cohort study. The inclusion criteria were hospitalized patients who received rehabilitation between April 2017 and February 2023. The exclusion criteria were patients who discontinued rehabilitation, were transferred to other hospitals, or died during the rehabilitation period. Rehabilitation consisted of physical therapy and/or occupational therapy provided six times a week, for both hospitalized HD and non-HD patients. The rehabilitation program comprised balance training, aerobic exercises, resistance training, and ADL training to prepare the patients for discharge to their homes. We measured several outcomes in the study, including the daily duration of rehabilitation (min/day), length of hospital stay (days), Barthel index (BI), as the ADL index, at the time of admission and discharge, grip strength and isometric knee extension strength (IKES) as muscle strength indices, and the 10-meter walking speed, timed up and go test (TUG), and short physical performance battery (SPPB) as mobility function indices. For the statistical analysis, missing values were completed by using multiple imputation methods. The inverse probability weighting (IPTW) method was used to match the HD group and non-HD group to adjust for confounding factors. The outcomes between the groups were then compared using a generalized linear model analysis. All procedures in the present study were conducted with the approval of the ethics committee of Seirei Christopher University. Results Of 1002 patients who were registered for the study, 100 patients who discontinued rehabilitation, were transferred to other hospitals, or died were excluded, and the data of the remaining 902 patients (765 of the non-HD group and 137 of the HD group) were included in the analysis in this study. The results of the generalized linear model analysis revealed a lower daily duration of rehabilitation [43.3(0.6) vs. 38.8(1.2) min/day, p=0.0003] and longer length of hospital stay [48.5(0.5) vs. 58.1(2.3) days, p=0.0108] in the HD group. In addition, the 10-meter walking speed [0.75(0.02) vs. 0.66(0.03) m/s, p=0.003] and scores on the TUG [20.8(0.7) vs. 24.3(1.0) sec, p=0.0021] and SPPB [6.3(4.57) vs. 4.7(0.6) points, p=0.0415] at discharge were also significantly lower in the HD group as compared with the non-HD group. There was no difference in the ability for ADL or muscle strength at discharge between the two groups. Conclusion This study was the first to demonstrate a lower daily duration of rehabilitation and longer hospital stay in hospitalized HD patients. Furthermore, rehabilitation had a lower impact on the mobility indices in HD patients as compared with non-HD patients. Although there was no difference in the ability for ADL or muscle strength at discharge between the two groups, HD patients exhibited a significantly lower ability for mobility functions, including a lower gait speed and lower scores on the TUG, and SPPB assessments. Therefore, rehabilitation efforts in HD patients need to be improved by securing more time for inpatient rehabilitation and promoting mobility function improvement.

Early pathophysiology-driven airway pressure release ventilation versus low tidal volume ventilation strategy for patients with moderate-severe ARDS: study protocol for a randomized, multicenter, controlled trial

BackgroundConventional Mechanical ventilation modes used for individuals suffering from acute respiratory distress syndrome have the potential to exacerbate lung injury through regional alveolar overinflation and/or repetitive alveolar collapse with shearing, known as atelectrauma. Animal studies have demonstrated that airway pressure release ventilation (APRV) offers distinct advantages over conventional mechanical ventilation modes. However, the methodologies for implementing APRV vary widely, and the findings from clinical studies remain controversial. This study (APRVplus trial), aims to assess the impact of an early pathophysiology-driven APRV ventilation approach compared to a low tidal volume ventilation (LTV) strategy on the prognosis of patients with moderate to severe ARDS.MethodsThe APRVplus trial is a prospective, multicenter, randomized clinical trial, building upon our prior single-center study, to enroll 840 patients from at least 35 hospitals in China. This investigation plans to compare the early pathophysiology-driven APRV ventilation approach with the control intervention of LTV lung-protective ventilation.The primary outcome measure will be all-cause mortality at 28 days after randomization in the intensive care units (ICU). Secondary outcome measures will include assessments of oxygenation, and physiology parameters at baseline, as well as on days 1, 2, and 3. Additionally, clinical outcomes such as ventilator-free days at 28 days, duration of ICU and hospital stay, ICU and hospital mortality, and the occurrence of adverse events will be evaluated.Trial ethics and disseminationThe research project has obtained approval from the Ethics Committee of West China Hospital of Sichuan University (2019-337). Informed consent is required. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.Trial registrationThe study was registered at Clinical Trials.gov (NCT03549910) on June 8, 2018.

#3048 Short and long term follow up of living Tunisian kidney donors

Abstract Background and Aims Over the years, concerns have increased about the harmlessness of kidney donation. This is more relevant in an Arab Muslim developing country like Tunisia, where lack of cadaveric donors is continuously leading to an increase in living donor numbers. The aim of this study is to evaluate the safety of nephrectomy as well as medical and surgical outcomes among LKDs, both short and long terms. Method Longitudinal monocentric study, involving a cohort of 106 LKDs in which nephrectomies were performed between November 2007 and April 2015. Donors that attended their follow-up visits after donation as per the European Renal Best Practice group recommendations by the European Renal Disease Association were included.10 Because of the irregularity of visits, we defined visits as follows: M1=from hospital discharge to the 3rd month, M3=from the 3rd month to 6th month, M6=from the 6th month to the 1st year, Y1=from the 1st year to 2nd year, Y2=from the 2nd year to the 4th year, and Y4=4 years and more. At the time of evaluation, we looked for the presence or history of renal events (i.e., elevation of serum creatinine level or proteinuria). We also detected by periodical check- up the presence or history of other physical or biological affections such as the presence of hypertension (HTN), diabetes mellitus (DM), sugar intolerance, hyperlipidemia, or hyper-uricemia (Table 1). Results 92 donors were included in the follow-up analysis after following exclusion criteria. The mean age at the time of nephrectomy was 42.8 ± 10 years with the sex ratio 0.6. and 27% of our donors were mothers. Twenty-two percent of the donors were obese and 4% were hypertensive. The median initial glomerular filtration rate (GFR) was 105 mL/min/1.73 m2. The surgical approach was costal lumbotomy in 96% of cases and laparoscopy for four cases. The kidneys were removed from the left side in 93% of cases. Postoperative mortality was zero and early postoperative morbidity was low. The median duration of hospital stay was nine days. During follow-up, 14% attended all recommended visits. The median follow- up duration was 26 months. After two years post donation, the prevalence of HTN was 28% and obesity was 26%. The prevalence of GFR decline (50–59 mL/min) was 14% using formula by modification of diet in renal disease. None of our donors reached stage 4 or 5 CKD. Twelve had proteinuria and one donor had diabetes, a comparable prevalence of morbidities to the general population Conclusion Our results are strong arguments for harmlessness of renal donation but emphasize the importance of a careful and science-based selection process. Post donation follow-up, seemingly insufficient in our study, is the only guarantor of short- and long-term safety for donors and therefore helps to encourage the act of donating in other potential donors.

#555 Acute graft pyelonephritis in a kidney transplant recipient—a single centre experience in northern India

Abstract Background and Aims Urinary tract infections (UTI) are the most common infections after kidney transplantation. Although clinical spectrum of pyelonephritis after kidney transplantation remain less clear. This study was conducted to evaluate the prevalence, clinical and microbiological profile with antibiogram of post-transplant pyelonephritis. Method We retrospectively reviewed and analysed the charts of 1684 patients, who underwent kidney transplantation at Medanta—The Medicity between January 2015 and May 2023. Patients were screened for the diagnosis of pyelonephritis and their clinical characteristics and outcome were evaluated. Results 93/1684 (5.5%) patients with a mean age of 41 ± 13.57 years had developed at least one episode of Pyelonephritis. 68 were males and 25 females. Older age, female gender, hyperglycaemia, use of induction immunosuppression were the risk factors for Pyelonephritis. Median time of occurrence was 44 days after transplantation. Most common symptoms were fever (n=64) followed by dysuria (n=40), and abdominal pain (n=11). Most common organism isolated was Escherichia coli (51.6%) followed by Klebsiella pneumonia (30.1%), and Pseudomonas aeruginosa (11.8%). This study showed a high percentage of resistance to commonly used antibiotics like Carbapenems (61.3%), third generation cephalosporin (49.5%). 41/93 (44%) patients had acute graft dysfunction at the time of presentation. Median duration of hospital stay was 7 days. 90/93 patients had graft recovery and one patient lost his graft after episode of UTI. Conclusion Pyelonephritis is a common cause of morbidity after kidney transplantation and occurs in an early post-transplant period. Gram negative bacilli are the major pathogens and carbapenems as an empirical therapy might be useful choice for management of Pyelonephritis and coverage of majority pathogens.

#1604 LACE index as predictors of 30 day rehospitalisation among patients on maintenance hemodialysis, cohort study

Abstract Background and Aims Over 35% of patients on maintenance dialysis are readmitted to the hospital within 30 days of hospital discharge. Validated risk assessment tools such as the LACE index (Length of stay, Acuity of admission, Co-morbidities, and Emergency department visits) have been developed to identify patients at high risk of hospital readmission in non-dialysis patients but have not been tested in dialysis patients. Method Data was collected from electronic medical records of patients on maintenance hemodialysis in Diaverum outpatient clinics hospitalized during 2023. Data included Age, gender, duration of hospital stay, Charlson comorbidity index (CCS), urgent or planned, and cause of Hospitalization. Multivariable logistic regression models with 30-day readmission for the same reason as the dependent outcome were used to identify readmission risk factors and whether the LACE score validly predicts 30-day rehospitalization among our cohort. Results Among (4829) patients received dialysis in Diaverum Saudi Arabia during 2023. (1487) episodes of hospitalization were reported due to various reasons rate of hospitalization was 0.54 Episodes per patient-years at risk, and 372(25%) of hospitalized patients were re-hospitalized for the same reason within 30 days. The proportion of patients with 30 days of rehospitalization for the same reason was higher in patients with post-initial discharge LACE index ≥10 in comparison to patients with LACE index&amp;lt;10, 348(32.6%) &amp; 24(5.7) respectively P-VALUE&amp;lt;0.001. also significantly higher in patients ≥65years old than those younger 163(27.7%) &amp;209(23.3%) respectively P-VALUE&amp;lt;0.05, those in high risk group (defined as those with higher comorbidity index ≥6 and/or lower Individual Patient Performance Score&amp;lt;75) than those who are not in high risk group 215(35%) &amp; 157(17.9%) respectively P-VALUE&amp;lt;0.001. Multivariate logistic regression including covariates significantly associated with higher 30-day rehospitalization to avoid confounder effect with model including ( age, gender, dialysis duration, body mass index, comorbidity index, diabetes, vascular access, cause of hospitalization and inclusion in high-risk group ) showed significantly higher rehospitalization in patients with post-initial discharge LACE index ≥10 in comparison to patients with LACE index&amp;lt;10 ODDS RATIO (95%CI) 7.95(5.1-12.5) P-VALUE&amp;lt;0.001. independent of other covariates in the model Conclusion LACE index at discharge is an independent predictor of (30) days re-hospitalization in patients on maintenance Hemodialysis. Further analysis needed for a specific model for HD patients taking into consideration the unique characteristics of this cohort of patients.

Evaluation of controlling nutritional status (CONUT) score in the prognosis of hyperemesis gravidarum.

To investigate the predictive value of the Controlling Nutritional Status (CONUT) score on hyperemesis gravidarum (HG) severity, hospitalization, and length of stay. This retrospective cross-sectional study, conducted between December 2022 and June 2023, involved two groups. Group 1 comprised 52 pregnant women diagnosed with HG in the first trimester, receiving hospitalization and treatment. Group 2 included 105 pregnant women diagnosed with HG in the first trimester, managed and treated as outpatients. The CONUT score was calculated with the formula: Serum albumin score+total lymphocyte score+total cholesterol score. This score is calculated with a number of points between 0 and 12. The interpretation of the score involves four categories: normal (0-1), light (2-4), moderate (5-8), and severe (9-12). The CONUT score differed significantly between the hospitalized (4, IQR: 2.25-5) and outpatient groups (2, IQR: 2-3) (p<0.001). A CONUT score >3 was associated with the need for hospitalization, demonstrating a sensitivity of 60%, aspecificity of 84% (p<0.001). The CONUT score was the parameter with the highest odds ratio (OR) value among the parameters related to the need for hospitalization, and each unit increase in the CONUT score increased the need for hospitalization by 1.683 times [OR=1.683 (95% CI: 1.042-2.718), p=0.033]. A positive correlation was found between the CONUT score and the duration of hospital stay (r=0.316, p=0.023). This study suggests CONUT score as a valuable tool for predicting HG severity, hospitalization need, and duration of hospital stay.

#1858 Delirium among patients admitted to a Nephrology ward-risk factors and association with short-term outcomes: an observational prospective cohort study

Abstract Background and Aims To date, delirium is considered one of the most frequent neuropsychiatric acute syndromes among hospitalized populations. In general medicine, the risk factors for delirium are well-established but there are limited data concerning the incidence and predictors of delirium in nephrological patients. The aims of the study were (i) to assess the prevalence and the risk factors for delirium in hospitalized patients with acute kidney injury (AKI) and chronic kidney disease (CKD), and (ii) to evaluate the effect of delirium on in-hospital mortality. Method A cohort of 942 patients admitted to the Nephrology Department of a tertiary-care Hospital from January 2023 to December 2023 were enrolled in a prospective observational study. Delirium was diagnosed by a psychiatrist during the hospitalization. The endpoint was defined as hospital death or hospital discharge. Relevant sociodemographic, nephrological- and medical-related clusters were assessed with logistic uni- and multivariable regression methods to evaluate their association with delirium and in-hospital mortality. A two-tailed value &amp;lt;0.05 was considered significant. Results In the studied group, mean age was 62.85 years, 519 (55.09%) patients being males. The prevalence of delirium was 5.41% (51/942 patients). The delirious patients were older (mean 70.04 vs. 62.44 years; P&amp;lt;0.001) and with a longer duration of hospitalization (13.12 ± 7.90 days vs. 10.76 ± 8.92 days; P=0.007). Univariable regression analysis showed that delirium was associated with age (r=0.117, P&amp;lt;0.001), alcohol abuse (r=0.144, P&amp;lt;0.001), history of stroke (r=0.184, P&amp;lt;0.001), vascular dementia (r=0.125, P&amp;lt;0.001), dehydration (r=0.175, P&amp;lt;0.001), sepsis (r=0.144, P&amp;lt;0.001), and acute kidney injury (AKI) stage 2 and 3 (r=0.155, P&amp;lt;0.001). In multivariable regression analysis, the independent predictors of delirium were: age (adjusted odds ratio (OR) 1.029, 95% confidence interval (CI): 1.002–1.056, P=0.034), alcohol abuse (OR=4.728, 95% CI: 1.968-11.359, P=0.001), history of stroke (OR=3.493, 95% CI: 1.849-6.598, P&amp;lt;0.001), and AKI stage 2 and 3 (OR=2.175, 95% CI: 1.152-4.105, P=0.017). Chronic kidney disease was not associated with a higher risk of delirium (OR=0.583, 95% CI: 0.308-1.110, P=0.097). Delirium was associated with increased in-hospital mortality (47.05% vs. no-delirium 14.36%, P&amp;lt;0.001) and was an independent predictor of in-hospital mortality (OR=3.074, 95% CI: 1.630-5.797, P=0.001). Conclusion In this study conducted on patients hospitalized in a nephrology ward age, alcohol abuse, history of stroke, and AKI stage 2 and 3 were independent risk factors for delirium. Delirium significantly increased in-hospital mortality. The findings of the study emphasize the strong connectivity between AKI and acute brain dysfunction.

Evaluation of the Efficacy and Safety of Intravenous Immunoglobulin (IVIG) in Moderate-to-Severe Hospitalized COVID-19 Patients: A Randomized, Open-Label Parallel-Group Study.

Since February 2020, the world has been overwhelmed by the SARS-CoV-2 outbreak, and several patients suffered interstitial pneumonia and respiratory failure requiring mechanical ventilation, threatening the capability of healthcare systems to handle this amount of critical cases. Intravenous immunoglobulins (IVIG) possess potential immunomodulatory properties beneficial for COVID-19 patients, yet evidence supporting IVIG as adjunctive therapy remains sparse. This study evaluated the outcomes of adjunctive IVIG with the standard of care (SoC) in moderate-to-severe COVID-19 patients. This randomized study included 59 moderate-to-severe COVID-19 patients with known comorbidities. One arm (n = 33) received high-dose IVIG (400 mg/kg/day) within 48 hours for five days alongside SoC, while the other arm (n = 26) received SoC, comprising steroids, enoxaparin, and remdesivir. The primary endpoint was clinical improvement, as measured by the National Early Warning Score 2 (NEWS2) and discharged/death proportions. Secondary outcomes included IVIG safety, hospitalization duration, changes in oxygen saturation, inflammatory markers, IgG titer, CTSS (CT severity score), and radiological findings. There was an improvement in the NEWS2 at the end of treatment in the IVIG arm (5.67 vs. 5.96). A significant absolute effect improvement (Day 1 vs. Day 9) was seen in serum LDH, D-dimer, hs-CRP, IL-6, CTSS, procalcitonin, respiratory rate, and chest radiographic findings. SARS-CoV-2 IgG titer increased significantly in the IVIG arm. There was a statistically significant reduction in mortality in the IVIG group (5 vs. 10). IVIG was a safe and effective adjunctive therapy to SoC treatment in moderate-to-severe COVID-19 patients needing ventilatory support. Furthermore, studies are required to validate our findings. This trial is registered with CTRI/2021/05/033622.
