Outcomes in robotic-assisted compared to laparoscopic-assisted colorectal surgery in a newly established colorectal tertiary center: a retrospective comparative cohort study.

The robotic platform matches or surpasses laparoscopic surgery in postoperative results. However, limited date and slow adoption are noticed in the middle east. We aimed to report outcomes of robotic and laparoscopic colorectal surgery performed by fellowship-trained robotic colorectal surgeons and compare it to larger more experienced centers. Retrospective review of prospectively collected data between 2021 and 2023 of 107 patients who had robotic-assisted or laparoscopic-assisted colorectal surgery was included in the study. The outcomes were overall morbidity, serious morbidity, mortality, conversion to open, length of hospital stay, and the quality of oncological specimen. Of 107 patients, 57 were in the robotic and 50 were in the laparoscopic surgery groups. Overall, there were no significant differences in overall morbidity (46.8 vs. 53.2%, p = 0.9), serious morbidity (10.5 vs. 8%, p = 0.7), or mortality (0 vs. 4%, p = 0.2). Regarding oncological outcomes, there were no significant difference between the two groups regarding the number of lymph node harvested (17.7 ± 6.9 vs 19.0 ± 9.7, p = 0.5), R0 resections (92.7 vs. 87.1%, p = 0.5), and the rate of complete mesorectal excision (92.7 vs. 71.4%, p = 0.19). The study found that the robotic group had an 86% reduction in conversion rate to open surgery compared to the laparoscopic group, despite including more obese and physically dependent patients (OR = 0.14, 95% CI 0.03-0.7, p = 0.01). Robotic surgery appears to be a safe and effective as laparoscopic surgery in smaller colorectal surgery programs led by fellowship-trained robotic surgeons, with outcomes comparable to those of larger programs.

The Association of Professional Burnout and Turnover Intentions Among Intensive Care Units Physicians: A Cross-Sectional Study.

Intensive Care Units (ICU) workers work in highly stressful conditions that make them prone to professional burnout, which can lead to high turnover rates. This study explores professional burnout levels among ICU workers in Kuwait general governmental hospitals (GGHs), their turnover intentions, and the correlation factors. A cross-sectional self-administered survey study was conducted. Professional burnout level was measured using the Copenhagen Burnout Inventory (CBI), while turnover intention was measured using the Turnover Intention Scale (TIS-6). Data were analyzed using STATA software, and descriptive, correlative, and comparative analyses were performed. Eighty-nine ICU physicians filled out the questionnaire. Most of the participants were males, married, non-Kuwaiti nationals, with 10 to 20 years of experience, and the mean age of respondents was 39.2. The total professional burnout score was high was 54.7 (17.6). There were high total average scores for the personal and work-related domains. Participants who were younger than 35 years of age and graduated before 5 to 10 years had higher levels of professional burnout compared to other groups. More than half of the sample expressed their intention to leave their current job as an ICU physician. However, no association was found between turnover intentions and levels of burnout. High levels of professional burnout of turnover intentions were seen among ICU physicians in Kuwait. Policies should be adopted to reduce and mitigate professional burnout among ICU physicians and increase their retention. Future research should further investigate professional burnout among ICU staff, the associated factors, and its relation to their turnover intention.

A Multicenter Study Evaluating the Discontinuation of Eculizumab Therapy in Children with Atypical Hemolytic Uremic Syndrome.

BACKGROUND: Atypical hemolytic uremic syndrome (aHUS) is a rare, life-threatening thrombotic microangiopathy (TMA), which has been treated successfully with eculizumab. The optimal duration of eculizumab in treating patients with aHUS remains poorly defined. METHODS: We conducted a multicenter retrospective study in the Arabian Gulf region for children of less than 18 years of age who were diagnosed with aHUS and who discontinued eculizumab between June 2013 and June 2021 to assess the rate and risk factors of aHUS recurrence. RESULTS: We analyzed 28 patients with a clinical diagnosis of aHUS who had discontinued eculizumab. The most common reason for the discontinuation of eculizumab was renal and hematological remission (71.4%), followed by negative genetic testing (28.6%). During a median follow-up period of 24 months after discontinuation, 8 patients (28.5%) experienced HUS relapse. The risk factors of recurrence were positive genetic mutations (p = 0.020). On the other hand, there was no significant relationship between the relapse and age of presentation, the need for acute dialysis, the duration of eculizumab therapy before discontinuation, or the timing of eculizumab after the presentation. Regarding the renal outcomes after discontinuation, 23 patients were in remission with normal renal function, while 4 patients had chronic kidney disease (CKD) (three of them had pre-existing chronic kidney disease (CKD) before discontinuation, and one case developed a new CKD after discontinuation) and one patient underwent transplantation. CONCLUSIONS: The discontinuation of eculizumab in patients with aHUS is not without risk; it can result in HUS recurrence. Eculizumab discontinuation can be performed with close monitoring of the patients. It is essential to assess risk the factors for relapse before eculizumab discontinuation, in particular in children with a positive complement variant and any degree of residual CKD, as HUS relapse may lead to additional loss of kidney function. Resuming eculizumab promptly after relapse is effective in most patients.

Usefulness of smartphone use among surgeons in clinical practice during the pandemic of COVID-19: a cross-sectional study.

BACKGROUND: With the magnitude and severity of the COVID-19 pandemic, the usual face-to-face consultation within a clinical setting is no longer feasible. Thus, this led to the need for alternate means to provide adequate patient care for surgical patients. This is where the role of smartphones comes into play, in which it is thus of paramount importance. This research study aimed to assess the usefulness of smartphones in surgical practice during COVID-19 pandemic. METHODS: This cross-sectional study is based on a questionnaire distributed among surgeons in different levels of practice working at Kuwait governmental hospitals during the COVID-19 pandemic. The questionnaire was developed via Google Docs to collect data for the current study. RESULTS: Out of 600 surgeons, 180 have responded to the questionnaire, giving a response rate of 30%. Of these, 42.8%, 85.5%, and 58.9% were aged between 35 and 44 years, were male, and Kuwaiti nationals, respectively. Almost all of the respondents (99.5%) were using smartphones for hospital-related work. The most common uses of the smartphones involved texting (70%), and viewing or taking images and videos using built-in cameras (60%) either in the emergency department, outpatient clinics, wards, or operating rooms. The majority of the respondents (88%) rated the use of smartphones in practice as important. CONCLUSION: This study revealed that using smartphones in surgical practice was prevalent among the respondent surgeons in Kuwait during the pandemic. The majority of them considered using smartphones in practice to be important, due to its benefits in facilitating doctor-doctor and patient-doctor communication, reviewing the literature, and making clinical decisions. Guidelines are required for proper and legal use of smartphone devices in medical practice. Accordingly, recommendations are suggested.

Total robotic surgical volume influences outcomes of low-volume robotic-assisted partial nephrectomy over an extended duration.

INTRODUCTION: The objective of this study was to examine the surgeon's experience of low-volume robotic-assisted partial nephrectomy (RAPN) over an extended duration, and whether a high-volume fellowship training influenced the outcomes. METHODS: Data on all RAPN at a tertiary center performed by a uro-oncologist were retrospectively collected. The surgeon experience was assessed by examining perioperative outcomes among three groups of consecutive patients (first=14, second=14, third=15 patients, respectively). RESULTS: Between February 2014 and February 2020, 45 RAPNs were performed out of a total of 200 robotic procedures. The median tumor size was 3 cm, and 28 (65%) patients had a R.E.N.A.L nephrometry score (RNS) ≥7. The median operative time and warm ischemia time (WIT) were 190 and 16 minutes, respectively. The median estimated blood loss (EBL) was 100 mL. Two (4%) patients had a positive surgical margin (PSM). Overall, five (12%) complications were recorded. All except one were minor (Clavien I-II). The median followup was 26.2 months. Trifecta and pentafecta were achieved in 40 (93%) and 27 (81.8%) patients, respectively. Increased surgeon experience was significantly associated with a shorter operative time and less EBL. Furthermore, there was an independent association between surgeon experience and operative time and EBL, and between RNS and operative time and WIT. CONCLUSIONS: With fellowship training and subsequent adequate total number of robotic procedures during practice, it is possible to perform RAPN with favorable perioperative outcomes in the setting of low-volume of cases over an extended duration.

Practice of Childhood Nephrotic Syndrome Management amongPediatric Nephrologists in the GCC Countries.

Childhood nephrotic syndrome (NS) management is greatly variable among pediatric nephrologists worldwide. We aimed to evaluate if this variability exists among pediatric nephrologists in the gulf countries and whether certain training programs influence this variability. A web-based multiple-choice survey of 35 NS management questions distributed to certified pediatric nephrologists working in the Gulf countries. Amongst 92 invitees, the response rate was 67%. The majority (73%) were older than 50 years and male (58%). Sixty percent trained in North America and 41% had >10 years of experience. Sixty-three percent use a 12- week corticosteroids regimen for the initial treatment of childhood NS and only 10% never consider long-term small alternate dose corticosteroids therapy to sustain remission before commencing a corticosteroids-sparing agent for frequently relapsing or corticosteroids-dependent NS. Mycophenolate mofetil was the drug of choice for frequently relapsing and corticosteroids dependent NS in 51% and 58% of the participants, respectively, whereas calcineurin inhibitors were preferred by the vast majority (95%) of the participants for corticosteroids-resistant childhood NS. Regarding rituximab treatment, almost half of the participants (48%) give two doses of rituximab one to two weeks apart and 61% do not give another course of rituximab until the child relapse. Fellowship training site and the duration of the clinical experience did not seem to influence certain management of childhood NS. As shown in North American studies, great variability in the management of childhood NS does exist in the Gulf countries. The country of fellowship training and the experience did not seem to contribute to this variability.

Pathological features of prostate cancer in men treated with robot-assisted radical prostatectomy in the Middle East.

Little is known about the pathological features of radical prostatectomy among men living in the Middle East. Although prostate cancer became the most common malignancy among males in some countries in the Middle East, the incidence is much lower compared to western populations. The aim of this study is to analyze pathological features and biochemical recurrence in men who underwent robotic-assisted radical prostatectomy (RARP) in Kuwait. The data on all RARP cases performed by a uro-oncologist (SA) were recorded. A comprehensive database was collected, including demographic, clinical, and pathological data. Between February 2014 and November 2019, 65 RARP cases were performed out of a total of 200 robotic urological procedures. The median follow-up was 41.5 months [inter quartile range (IQR) 27.6-52.7]. Eleven (17%) complications occurred in 7 patients, 64% were early (< 30 days post-operatively) and minor (Clavien I-II). Thirty-five (54%) patients had ≥ pT3 disease. Overall, 12 (18%) patients had a positive surgical margin (PSM), and all had ≥ pT3 disease. Potency and continence rates at 12 months were 82% and 97%, respectively. The mean and SD of the hospital stay were 2.7 ± 1.1 days. Biochemical recurrence (BCR) rate was 10%. Men with prostatic adenocarcinoma treated with RARP in Kuwait show a high incidence of pT3 disease. PSM and BCR rates were similar to multiple reports in the literature. To our knowledge, this is the first report of RARP pathological outcomes in the gulf cooperation council (GCC) region of the Middle East.

Seizures in a Child Post Renal Transplant: A Case of Disequilibrium Syndrome.

Disequilibrium syndrome is typically characterized by neurological manifestations that occur acutely posthemodialysis due to a significant drop in serum osmolality. We report a child with disequilibrium syndrome postrenal transplant and compare this presentation to previously reported cases.

A population-based study of the epidemiology and the risk factors for male infertility in Kuwait.

PURPOSE: Infertility has become one of the foremost public health concerns, affecting a large number of couples. This research aimed to study and analyze the epidemiological data of male infertility including demographic characteristics and potential accountable factors. MATERIALS AND METHODS: A population-based study was carried out among male patients of one center. Different factors have been investigated such as family history, smoking, and varicocele. Data were analyzed using the STATA statistical software package. RESULTS: A total of 608 male patients aged between 22 and 56 years were included. Out of them, there were 544 (89.95%) married, 48 (7.9%) married more than once, and 10 (1.6%) divorced. Primary infertility was noted in 478 (78.6%) patients. The most commonly reported sexual disorder was erectile dysfunction 53 (8.7%), while decreased libido was detected in 8 (1.3%) patients. Varicocele was present among 507 (86%) patients. Semen analyses of infertile patients revealed that 43 (8.2%) cases had normal semen tests. In contrast, oligoasthenospermia was the most commonly reported semen abnormality 158 (30.2%). A total of 198 patients underwent assisted reproductive technique. CONCLUSION: This study concluded that primary infertility is the most common type among all infertile male patients who visited our center. The risk factors of male infertility include positive family history, smoking, and varicocele.

Acute Kidney Injury in Children with Kidney Transplantation.

BACKGROUND AND OBJECTIVES: AKI is associated with progression of CKD. Little is known about AKI after kidney transplantation in pediatric recipients. We aim to describe the epidemiology, risk factors, consequences, and outcomes of AKI in this population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed a retrospective longitudinal analysis of pediatric kidney transplant recipients followed at The Hospital for Sick Children (Toronto, Canada) from 2001 to 2012. AKI was defined as an increase in serum creatinine ≥1.5 times baseline, and a rise of serum creatinine ≥1.25 but <1.5 times baseline defined subacute AKI. RESULTS: Of 179 children, 122 were eligible for analysis. At baseline (3 months post-transplant), median age of the children was 13 years old (interquartile range, 9-16 years old), and 53% had CKD stage 2. Congenital anomalies of the kidney and urinary tract accounted for 46% of children. Over the study period (12 years), the incidence of AKI was 37% (n=45 children), and 65% (79 children) experienced subacute AKI. Twenty-seven percent (33 children) did not develop AKI or subacute AKI. The main causes of AKI were infections other than urinary tract infections, rejection, and urinary tract infections. In a multivariable Poisson regression analysis, independent risk factors for AKI included younger age, girls, grafts from deceased donors, and lower baseline eGFR. AKI was significantly associated with lower long-term GFR and graft loss independent of rejection episodes. Moreover, subacute AKI was associated with progression of CKD. CONCLUSIONS: AKI and subacute AKI were common after pediatric kidney transplantation, and they were associated with graft loss, lower eGFR, and more rapid progression of CKD.

Complement depletion and Coombs positivity in pneumococcal hemolytic uremic syndrome (pnHUS). Case series and plea to revisit an old pathogenetic concept.

Hemolytic uremic syndrome is a rare complication of invasive pneumococcal infection (pnHUS). Its pathogenesis is poorly understood, and treatment remains controversial. The emerging role of complement in various forms of HUS warrants a new look at this "old" disease. We performed a retrospective analysis of clinical and laboratory features of three sequential cases of pnHUS since 2008 associated with pneumonia/pleural empyema, two due to Streptococcus pneumoniae serotype 19 A. Profound depletion of complement C3 (and less of C4) was observed in two patients. One patient was Coombs test positive. Her red blood cells (RBCs) strongly agglutinated with blood group compatible donor serum at 0 °C, but not at 37 °C. All three patients were treated with hemodialysis, concentrated RBCs, and platelets. Patient 2 received frozen plasma for hepatic failure with coagulation factor depletion. Intravenous immunoglobulin infusion, intended to neutralize pneumococcal neuraminidase in patient 3, was associated with rapid normalization of platelets and cessation of hemolysis. Two patients recovered without sequelae or disease recurrence. Patient 2 died within 2½ days of admission due to complicating Pseudomonas aeruginosa sepsis and multiorgan failure. Our observations suggest that pnHUS can be associated with dramatic, transient complement consumption early in the course of the disease, probably via the alternative pathway. A critical review of the literature and the reported cases argue against the postulated pathological role of preformed antibodies against the neuraminidase-exposed Thomsen-Friedenreich neoantigen (T antigen) in pnHUS. The improved understanding of complement regulation and bacterial strategies of complement evasion allows to propose a testable, new pathogenetic model of pnHUS. This model shifts emphasis from the action of natural anti-T antibodies toward impaired Complement Factor H (CFH) binding and function on desialylated membranes. Removal of neuraminic acid residues converts (protected) self to non-self surfaces that supports membrane attack complex (MAC) assembly. Complement activation is potentially exacerbated by decreased CFH availability following tight CFH binding to pneumococcal evasion proteins and/or by the presence of genetic variants of complement regulator proteins. Detailed clinical and experimental investigations are warranted to better understand the role of unregulated complement activation in pnHUS. Instead of avoidance of plasma, a new, integrated model is evolving, which may include short-term therapeutic complement blockade, particularly where genetic or functional APC dysregulation is suspected, in addition to bacterial elimination and, potentially, neuraminidase neutralization.

Validation of serum creatinine-based formulae in pediatric renal transplant recipients.

BackgroundAccurate monitoring of kidney function is important post-renal transplant; however, the routine use of measured glomerular filtration rate (GFR) or addition of newer serum markers is prohibitively expensive for routine clinical use, especially in children. We validated the modified Schwartz formula in pediatric renal transplant recipients across a range of demographic and clinical characteristics.MethodsIn a retrospective cohort study with nested cross-sectional analysis, we compared 505 measurements of estimated GFR using serum creatinine to simultaneous diethylenetriaminepentaacetic acid (DTPA) nuclear GFR (nGFR) measurements from 173 pediatric kidney transplant recipients who were < 18 years of age from 1 January 2001 to 31 December 2012 accounting for repeated measures.ResultsAmong 173 children, 62% were males, 85% with nGFR of ≥60 ml/min/1.73 m2, and the median age at transplant was 13.6 years (interquartile range 8.3-16 years). Overall, the modified Schwartz and Pottel formulae had better bias (0.07 and -0.03 ml/min/1.73 m2, respectively) and accuracy within 30% (both 84.4%) in comparison to Lyon and Zappitelli formulae. The 30% accuracy varied for girls and children <5 and >15 years.ConclusionModified Schwartz is a practical, non-invasive, and a valid bedside tool that provides a valid measurement of GFR in pediatric kidney transplant recipients.

Renal transplantation in Bardet-Biedl Syndrome.

BACKGROUND: Renal anomalies are common in patients with Bardet-Biedl syndrome (BBS), a renal cystic ciliopathy with multi-systemic features. Renal transplantation is indicated in cases of end-stage renal disease (ESRD), but transplant centers may be hesitant to perform the necessary transplant in light of the multitude of metabolic comorbidities these patients often face with the potential to complicate outcomes. METHODS: Data from the Clinical Registry Investigating BBS (CRIBBS) were used to investigate renal transplant outcomes in the largest BBS cohort described to date. RESULTS: Of the 206 patients enrolled in the CRIBBS, 21 children (10.2 %; 16 girls, 5 boys; median age 8.4 years) had been diagnosed with ESRD. Renal transplantation was performed in 18 of these individuals between 1982 and 2015, including repeat transplantation in some cases, for a total of 22 kidneys. Overall graft survival was 81.6 % at 1 year post-transplantation, 75.7 % at 5 years, 59 % at 10 years, and 49.2 % at 25 years. Patient survival was 94.4 % at 1 year post-transplantation, 87.2 % at 8 years, and 79.3 % at 25 years. CONCLUSIONS: At a median follow-up time of 97 months, relatively few complications of renal transplantation were reported in the patients of this study. However, body mass index was significantly elevated in transplanted individuals compared to non-transplanted individuals participating in CRIBBS at the most recent follow-up. Although the frequency of obesity and other manifestations of the metabolic syndrome warrant meticulous management in this high-risk population, favorable long-term outcomes suggest that renal transplantation is a viable option for patients with BBS and ESRD.

Recurrent Focal Segmental Glomerulosclerosis and Abatacept: Case Report.

Focal segmental glomerulosclerosis is a common cause of end-stage renal disease in children. Focal segmental glomerulosclerosis recurrence in renal transplants is a challenging disease, and can cause graft dysfunction and loss. Different therapies exist with varying responses, from complete remission to resistance to all modes of treatment. Abatacept was recently introduced as a treatment for primary focal segmental glomerulosclerosis in native kidneys and in recurrent disease after transplant. We present a pediatric case with immunosuppression-resistant primary NPHS2-negative focal segmental glomerulosclerosis recur-rence after renal transplant. The standard therapy for recurrent focal segmental glomerulosclerosis (rituximab, plasmapheresis, high-dose cyclosporine, and corticosteroids) was tried but failed to induce remission. Abatacept (10 mg/kg) was given at 0, 2, and 4 weeks (total, 3 doses) with no good response. We conclude that abatacept may work in patients with B7-1-positive focal segmental glomerulosclerosis recurrence and its efficacy is uncertain in disease with B7-1-negative or unknown staining status.

Acute kidney injury is an independent risk factor for pediatric intensive care unit mortality, longer length of stay and prolonged mechanical ventilation in critically ill children: a two-center retrospective cohort study.

INTRODUCTION: In adults, small (< 50%) serum creatinine (SCr) increases predict mortality. It is unclear whether different baseline serum creatinine (bSCr) estimation methods affect findings of acute kidney injury (AKI)-outcome associations. We characterized pediatric AKI, evaluated the effect of bSCr estimation approaches on AKI-outcome associations and evaluated the use of small SCr increases to predict AKI development. METHODS: We conducted a retrospective cohort database study of children (excluding postoperative cardiac or renal transplant patients) admitted to two pediatric intensive care units (PICUs) for at least one night in Montreal, QC, Canada. The AKI definition was based on the Acute Kidney Injury Network staging system, excluding the requirement of SCr increase within 48 hours, which was impossible to evaluate on the basis of our data set. We estimated bSCr two ways: (1) the lowest SCr level in the three months before admission or the average age- and gender-based norms (the standard method) or (2) by using average norms in all patients. Outcomes were PICU mortality and length of stay as well as required mechanical ventilation. We used multiple logistic regression analysis to evaluate AKI risk factors and the association between AKI and mortality. We used multiple linear regression analysis to evaluate the effect of AKI on other outcomes. We calculated diagnostic characteristics for early SCr increase (< 50%) to predict AKI development. RESULTS: Of 2,106 admissions (mean age ± SD = 5.0 ± 5.5 years; 47% female), 377 patients (17.9%) developed AKI (using the standard bSCr method) during PICU admission. Higher Pediatric Risk of Mortality score, required mechanical ventilation, documented infection and having a bSCr measurement were independent predictors of AKI development. AKI was associated with increased mortality (adjusted odds ratio (OR) = 3.7, 95% confidence interval (95% CI) = 2.1 to 6.4, using the standard bSCr method; OR = 4.5, 95% CI = 2.6 to 7.9, using normative bSCr values in all patients). AKI was independently associated with longer PICU stay and required mechanical ventilation. In children with no admission AKI, the initial percentage SCr increase predicted AKI development (area under the curve = 0.67, 95% CI = 0.60 to 0.74). CONCLUSIONS: AKI is associated with increased mortality and morbidity in critically ill children, regardless of the bSCr used. Paying attention to small early SCr increases may contribute to early AKI diagnosis in conjunction with other new AKI biomarkers.

A small post-operative rise in serum creatinine predicts acute kidney injury in children undergoing cardiac surgery.

To predict development of acute kidney injury and its outcome we retrospectively studied children having cardiac surgery. Acute kidney injury (AKI) was defined using the serum creatinine criteria of the pediatric Risk Injury Failure Loss End-Stage (pRIFLE) kidney disease definition. We tested whether a small rise (less than 50%) in creatinine on post-operative days 1 or 2 could predict a greater than 50% increase in serum creatinine within 48 h in 390 children. AKI occurred in 36% of patients, mostly in the first 4 post-operative days. Using logistic regression, significant independent risk factors for AKI were bypass time, longer vasopressor use, and a tendency for younger age. Using Cox regression, AKI was independently associated with longer intensive care unit stay and duration of ventilation. Patients whose serum creatinine did not increase on post-operative days 1 or 2 were unlikely to develop AKI (negative predictive values of 87 and 98%, respectively). Percentage serum creatinine rise on post-operative day 1 predicted AKI within 48 h (area under the curve=0.65). Our study shows that AKI after pediatric heart surgery is common and is a risk factor for poorer outcome. Small post-operative increases in serum creatinine may assist in the early prediction of AKI.
