Clinical and epidemiological features and therapeutic options of avascular necrosis in patients with sickle cell disease (SCD): a cross-sectional study.

BACKGROUND: Avascular necrosis (AVN) is a debilitating complication in sickle cell disease (SCD) patients, and its management is usually challenging. This study aims to evaluate the clinical and epidemiological features and therapeutic options of AVN in sickle cell patients in Qatar. PATIENTS AND METHODS: A cross-sectional study was conducted on a 49 SCD patients who were diagnosed with AVN and attended the hematology clinic at the National Center for Cancer care & research, Hamad Medical Corporation, Qatar between Jan-2011 to Jan2021.  Results: Forty-nine adult patients with SCD who were diagnosed with AVN were studied. The median age of the study population is 32 years, and the median age at the first AVN diagnosis was 26 years (range: 11-44 yr.). 37 (75.5%) patients suffered from multiple joints AVN while 12(24.5%) had single joint involvement. 31 (63.3%) patients had bilateral hip AVN and 18 (36.7%) had shoulder involvement. 30 patients (61%) were on Hydroxyurea treatment. Based on FICAT and Alert classification of AVN, 57 % of patients had stage III and above at first diagnosis. 20 (40.8%) were managed with a conservative approach, 11 (22.4%) received hyperbaric oxygen with good response, 6(12.2%) underwent hip core decompression and 12(24.5%) underwent hip replacement surgery. CONCLUSION: In SCD patients, AVN occurred more during the 3rd and 4th decades of life. The majority of AVN represented with advanced stage and had multiple joint involvements. We recommend adopting a low threshold of joint imaging for early detection and prevention of further complications.

Concentration effect of DMSO-dry bonding on the stability of etch-and-rinse bonds.

OBJECTIVES: To examine whether lower dimethyl sulfoxide (DMSO) concentrations would affect long-term bond stability of simplified or multistep water-based adhesives to dry-etched dentin. METHODS: H3PO4-etched mid-coronal dentin surfaces from human molars were randomly blot- or air-dried for 30 s and pretreated or not with 5 or 50 % (v/v) ethanolic DMSO solutions. Untreated samples served as control. Samples were bonded with a two-step or a three-step etch-and-rinse adhesive. Restored crown segments (n = 5/group) were stored in distilled water for 24 h and sectioned for microtensile bond strength testing. Resin-dentin beams (0.8 mm2) were tested under tension until fracture (0.5 mm/min) after 24 h and one year of storage in artificial saliva at 37 °C. Nanoleakage evaluation and hybrid layer characterization were performed by SEM. Bond strength data was examined by three-way ANOVA followed by the Tukey test (α = 0.05). RESULTS: Dry bonding produced significantly lower bond strengths than conventional wet bonding for both water-based adhesive systems (p < 0.05). DMSO-dry bonding restored bond strengths and reduced nanoleakage levels, regardless of adhesive type or DMSO concentration (p < 0.05). Bond strengths of DMSO-dry bonded samples were not significantly affected by long-term ageing regardless of adhesive type or DMSO concentration (p < 0.05). SIGNIFICANCE: Although bonding methacrylate-based resins to etched dentin is normally performed under wet conditions, hybridization of air-dried collagen can outperform conventional wet bonding by employing water-free DMSO solutions with concentrations as low as 5 %. Reduced moisture-related technique sensitivity, higher bonding performance and improved hybrid layer stability may contribute to extend the service life of resin-dentin bonding.

Body contouring after bariatric surgeries in Jordan: Awareness, prevalence, and challenges: A multicentric cross-sectional study.

Body-contouring surgeries are known to improve the quality of life and body image of patients undergoing bariatric surgery. However, only a small number of patients choose to undergo body-contouring surgeries. This study evaluated the prevalence of body-contouring surgeries among patients who underwent bariatric surgery in Jordan, and identified the limitations encountered. This study is an observational multicentric cross-sectional study. A validated questionnaire was distributed to patients who had undergone bariatric surgeries between July 2017 and June 2021 at the University of Jordan Hospital and a bariatric surgery private center in Amman, Jordan. Inclusion criteria were based on the type of bariatric surgery (Sleeve Gastrectomy or Roux-En-Y gastric bypass) and the surgery date falling within the study period, with participation requiring the completion of an online questionnaire. Collected data was analyzed using various statistical tests, with a predetermined alpha level of 0.05 to determine statistical significance. Of 451 eligible participants, a total of 305 patients completed the validated questionnaire. Of these, 11 responses were excluded due to incomplete data. The analysis focused on remaining 294 participants who underwent bariatric surgery between July 2017 and June 2021, with only 7 participants (2.4%) electing to undergo body-contouring surgeries. The primary barriers to body-contouring surgeries reported by participants were cost (62.7%) and fear of postoperative complications (31.8%). Females exhibited a significantly greater desire for body-contouring surgeries (P = .000), which was also related to the percentage of total weight loss following bariatric surgery (P = .025). However, no significant associations were observed between desiring body-contouring surgeries and marital status (P = .734) or employment status (P = .319). The low rate of body-contouring surgeries in Jordan reflects the importance of strengthening the patient-physician relationship through targeted education efforts that emphasize the expected consequences of bariatric surgery and the available solutions to address them. Additionally, encouraging collaboration among caregivers, healthcare authorities, and insurance providers is necessary to develop more inclusive treatment plans that are tailored to meet the diverse needs and socioeconomic backgrounds of patients.

Exploring the Roles and Responsibilities of an Educational Supervisor in Medical Training Within the United Kingdom.

Medical trainees or junior doctors within the United Kingdom, regardless of their level of training or specialty, are assigned an educational supervisor (ES). The General Medical Council within the United Kingdom defines an ES as "a trainer who is selected and appropriately trained to be responsible for the overall supervision and management of a specified trainee's educational progress during a clinical placement or series of placements." This article critically evaluates the current literature to explore the roles of the ES in supporting and monitoring a trainee's progress while discussing challenges associated with the role. Through clearer delineation of the role of an ES, barriers to improving training can be identified and overcome, thus improving overall satisfaction with training.

Knowledge and attitude towards monkeypox among the Lebanese population and their attitude towards vaccination.

Introduction: Monkeypox is a currently re-emerging disease in the world and several cases have been detected in Lebanon. For this reason, an assessment of the knowledge and attitude of the Lebanese population towards monkeypox and smallpox or monkeypox vaccines had to be done. Methods: A cross-sectional study was conducted using a questionnaire developed from previous literature among a sample of Lebanese residents. It recorded the sociodemographic characteristics and comorbidities of the participants and analyzed the patterns of knowledge and attitudes in Lebanon. Results: Among 493 participants, it was found that there is a generally low knowledge of and an average attitude toward monkeypox. However, knowledge is better with higher educational levels, COVID-19 vaccination, and residency in the south of Lebanon and poorer with marriage and residency in Beirut. Attitude is better in females but poorer with higher educational levels. Several other effectors have been devised too. As for vaccination, taking the smallpox vaccine as a proactive measure is predicted with previous COVID-19 vaccination and better attitude but not in the residents of the north of Lebanon and married Lebanese residents. Higher educational levels and a better attitude were positive predictions of taking the monkeypox vaccine whenever it is developed. Conclusion: This study revealed low level of knowledge and attitude towards monkeypox and its vaccines, which can be a rich resource when proactive measures are developed.

Exploring the Role of Urocortin in Osteoporosis.

Osteoporosis is a debilitating disease that affects over 200 million people worldwide. Overactive osteoclast activity leads to micro-architectural defects and low bone mass. This culminates in fragility fractures, such as femoral neck fractures. Treatments currently available either are not completely effective or have considerable side effects; thus, there is a need for more effective treatments. The urocortin (Ucn) family, composed of urocortin 1 (Ucn1), urocortin 2 (Ucn2), urocortin 3 (Ucn3), corticotropin-releasing factor (CRF) and corticotropin-releasing factor-binding protein (CRF-BP), exerts a wide range of effects throughout the body. Ucn1 has been shown to inhibit murine osteoclast activity. This review article will aim to bridge the gap between existing knowledge of Ucn and whether it can affect human osteoclasts.

Myocardial Infarction as an Initial Presentation of Essential Thrombocythemia With Calreticulin (CALR) Mutation (None Type 1, None Type 2).

Essential thrombocythemia (ET) is one of the classical Philadelphia-negative myeloproliferative neoplasms with different mutations that can be associated with it, like Janus kinase 2 (JAK2), myeloproliferative leukemia protein (MPL), and Calreticulin (CALR) (types 1 and 2). However, there is a lack in the literature concerning other types of CALR mutations and their clinical significance and prognosis. Here we report a 42-year-old male with type 2 diabetes who presented with an inferior ST-elevation myocardial infarction and thrombocytosis. The diagnosis of ET with CALR (neither type 1 nor type 2) was confirmed, which suggests the pathognomonic feature of this mutation.

Acute Limb Ischemia in Pediatric Intensive Care Units.

BACKGROUND: To determine the outcome of children treated for acute limb ischemia (ALI) in pediatric intensive care units (ICUs). METHODS: A single-center, retrospective cohort study including all patients diagnosed with ALI between 2005 and 2022 in 2 different pediatric ICUs: respiratory and cardiac ICU. Data collected included patients demographics and comorbidities, location and cause of arterial occlusion, and type and duration of therapy. Primary end point was freedom from amputation. Secondary end point was all-cause mortality. RESULTS: A total of 78 patients (58% male) with ALI were included in the study. Median age was 3.8 months (range 0.03-201). The lower extremity was involved in 55 (70%) patients. The limb ischemia was caused by arterial instrumentation in 94% of the patients. Anticoagulation was administered as the first-line therapy in all patients. Unfractionated heparin was administered for a median duration of 5 days (range 1-48). Low molecular weight heparin was continued for a median period of 28 days (range 4-420). Thrombolytic therapy was administered in 5 patients and 2 required surgical revascularization, all for failure of anticoagulation therapy. Mean follow-up was 21 months (range 1-188 months). None of the patients required major upper or lower extremity amputations during or after the index admission. Overall survival at 30 months was 68%. The causes of mortalities were unrelated to the limb ischemia. CONCLUSIONS: This large, single-center study demonstrates that ALI in the pediatric ICU population can be treated conservatively and is associated with a low amputation rate following nonoperative management. The favorable outcome exists regardless of the etiology of the ALI and underlying diseases.

Menstrual abnormalities post-COVID vaccination: a cross-sectional study on adult Lebanese women.

BACKGROUND: In the year 2020, the coronavirus pandemic invaded the world. Since then, specialized companies began to compete, producing many vaccines. Coronavirus vaccines have different adverse events. Menstrual disorders have been noticed as a common complaint post-vaccination. AIM: Our study fills an important gap by evaluating the relationship between coronavirus vaccines and menstrual disorders. METHODS: This is a cross-sectional study between 20 September 2021, and 1 October 2021, using an online survey. The questionnaire consisted of 36 questions divided into 4 sections: demographics, COVID-19 exposure and vaccination, hormonal background, and details about the menstrual cycle. Sample t-test, ANOVA test, chi-square, and McNemar test were used in bivariate analysis. RESULTS: This study includes 505 Lebanese adult women vaccinated against COVID-19. After vaccination, the number of women having heavy bleeding or light bleeding increased (p = 0.02 and p < 0.001, respectively). The number of women having regular cycles decreased after taking the vaccine (p < 0.001). Irregularity in the cycle post-vaccination was associated with worse PMS symptoms (p = 0.036). Women using hormonal contraception method or using any hormonal therapy had higher menstrual irregularity rates (p = 0.002 and p = 0.043, respectively). Concerning vaccine adverse events, those who had headaches had a higher rate of irregularity (p = 0.041). Those having PCOS, osteoporosis, or blood coagulation disorders had higher irregularity rate (p < 0.001 and p = 0.005, respectively). CONCLUSION: Vaccine adverse events may include specific menstrual irregularities. Moreover, some hormonal medications and diseases are associated with the alteration of the menstrual cycle. This study helps in predicting vaccines' menstrual adverse events, especially in a specific population prone to menstrual disorders.

Prevalence of Body Dysmorphic Disorder (BDD) among the Lebanese University students: associated risk factors and repercussion on mental health.

Introduction: Body Dysmorphic Disorder (BDD) is a psychological illness characterized by persistent and intrusive preoccupation with an imagined or slight defect in appearance. This study aimed to determine the prevalence of BDD and investigate its association with mental health status (depression and anxiety), religiosity, eating disorder risk, and self-esteem among Lebanese University students. Methods: A cross-sectional study was conducted in March 2020, involving students from the Lebanese University. Data were collected using the dysmorphic concern questionnaire (DCQ), Rosenberg self-esteem scale (RSE), religiosity scale, patient health questionnaire (PHQ-9), generalized anxiety disorder assessment (GAD-7), Eating Attitude test-26 scale (EAT-26). Results: A total of 6,448 participants were enrolled in our study. The overall prevalence of BDD among university students was (6.4%).Our results showed that Lebanese students with BDD were more likely to have anxiety ORadj 1.3 (95% CI: 1.2-1.7) p-value 0.001, depression ORadj 1.2 (95% CI: 1.15-1.5) p-value 0.007, and eating disorder (Bulimia & Food preoccupation ORadj 1.06 (95% CI: 1.03-1.2) p-value 0.0, and oral control ORadj 1.09 (95% CI: 1.05-1.1) p-value < 0.001) compared to those with no BDD. We also found that students with BDD had Lower Self-esteem ORadj 0.88 (95% CI: 0.78-0.9) p-value < 0.001), and less likely to be religious ORadj 0.88 (95% CI: 0.82-0.9) p-value 0.02) compared to those with no BDD. Conclusions: This pioneering study sheds light on the prevalence of BDD among Lebanese university students and its associated factors. Our findings underscore the importance of early detection of BDD during adolescence and young adulthood, necessitating timely psychological intervention to prevent chronicity and complications.

Value of Drains in Soft-Tissue Tumour Surgery: A Specialist Regional Centre Experience.

Background The mainstay of therapy in most soft-tissue tumours (STTs) is excision. However, this often results in blood/extracellular fluid collection within large dead spaces necessitating the use of surgical drains. Whether meticulous attention to haemostasis, careful closure of dead space, and use of compression bandage obviates the need for drains was investigated. This study aimed to compare postoperative outcomes in patients undergoing surgery for STTs with and without the use of drains. Methodology A retrospective analysis of patients undergoing STT surgery over five years was undertaken using a regional STT specialist service database. Patients were stratified into the following two groups: compression bandage alone (CB) versus compression bandage with drain (CBD). The chi-square test was used to examine associations with infection, seroma, and haematoma, while the unpaired t-test was used for associations with hospital stay and time to wound healing. The unpaired t-test with Bonferroni correction was used to account for tumour dimensions across both groups. Results A total of 81 CB and 25 CBD patients were included. The mean hospital stay was significantly lower in CB compared to CBD (4.9 days, SD = 8.574 vs. 9.8 days, SD = 7.647, p = 0.0125). None of the other variables was significantly different between the two groups, including infection (21.3% vs. 24.0%, p = 0.7804), seroma (25.0% vs. 36.0%, p = 0.2865), haematoma (0.026% vs. 2.0%, p = 0.2325), and time to wound healing (55.8 days, SD = 63.59 vs. 42.3 days, SD = 58.88, p = 0.3648). Conclusions Our findings suggest that the use of drains in patients undergoing STT tumour surgery lengthens hospital stay without reducing the incidence of postoperative complications/time to wound healing. A larger, prospective trial is needed.

Adult Stem Cells for Cartilage Regeneration.

As cartilage is an avascular, aneural structure, it has very low capabilities of self-repair. Osteoarthritis prevalence is increasing, and there are no clinically approved management techniques that can cure the degradation of cartilage. This report investigates the efficacy of different sources of cells to generate articular cartilage. Autologous chondrocyte implantation has been used to some extent in clinics; however it has not generated efficient, reliable results, and there is no evidence of long-term success. The usage of stem cells is more promising, particularly mesenchymal stem cells (MSCs). Human embryonic stem cells (hESCs) have also been trialed; however, it is important to note that the process of differentiation into chondrocytes is not fully understood, and the cartilage produced can often be of poor quality. MSCs seems to be the way forward, and hESCs will perhaps need further study with the usage of MSC differentiation methodology.

Lebanese University Students and COVID-19: A Survey on their Related-Knowledge, Practice, and Behaviors.

Introduction: Young adults are at the epicenter for preventing the progression of COVID-19 pandemic and must be targeted for education to impede any potential transmission of the disease. This study aimed to assess the knowledge, practice and behaviors of Lebanese university students regarding COVID-19. Methods: A cross-sectional study was carried out among university students at the Lebanese University between March 30, 2020, and April 4, 2020. Information on socio-demographic data, knowledge, practice, and additional information concerning COVID-19 were collected. Results: Our survey showed that the majority of the students had good knowledge 90.8%, and more than two third of the respondents 78.6% reported good practice regarding COVID-19. Graduate students were more knowledgeable compared to undergraduate students (unstandardized beta 0.349 with a 95% confidence interval (CI) of 0.165 to 0.533; p-value < 0.0001). Moreover, male students had a negative impact on good practice compared to females (unstandardized beta -0.280 with a 95% confidence interval (CI) of -0.402 to -0.159; p-value < 0.0001). Nearly half of the students (55.2%) reported that their food intake has increased, and 82.5% of the students didn't practice sport during the quarantine. The most common information source of the students was the television (63.3%) followed by social media (53.9%). Conclusions: This study offers useful insights into the knowledge and practices of Lebanese university students towards COVID-19. Our findings support the importance to deliver health education campaign by the ministry of public health through television and social media to improve the knowledge on disease transmission and preventive measures.

The Impact of Ethnicity on the Response to Eltrombopag in Patients With Immune Thrombocytopenia (ITP) in Qatar: A Single Institution Experience.

BACKGROUND: Eltrombopag olamine (ELT) is a synthetic nonpeptide with a low molecular weight that has been investigated in various phase-3 studies and shown to be efficacious at a typical dose of 50 mg. Varied ethnic groups have reported different responses to ELT. AIM: The aim is to examine the efficacy of ELT in Asian and Arab patients with immune thrombocytopenia (ITP) from the Indian subcontinent by starting with (12.5 mg, as a minimum dose) and gradually increasing to a maximum dose of 50 mg. METHODS: Between January 2015 and January 2019, we reviewed the electronic health records of non-Arab Asian (n = 17) versus Arab (n = 41) patients who were ≥18 years old, residing in Qatar, and with confirmed diagnoses with chronic ITP and under active treatment with a platelet count of 30,000/L, and bleeding symptoms. Following receiving ELT for three months or longer at various dosages, patients' response was examined. RESULTS: After three months of ELT therapy, the response rate (platelet count of 50,000/L) was equivalent in non-Arab (88.2%) versus Arab (87.5%) patients. However, to achieve an adequate response, 26% of Arab patients required a lower dose of 12.5 or 25 mg, and 41.5% required a higher dose of 50 mg. CONCLUSION:  In adult chronic ITP patients, ELT is typically well-tolerated and delivers the desired outcomes. In 67.5% of Arab patients, smaller dosages of ELT (12.5-50 mg) were helpful in sustaining acceptable PLT levels. This helps patients get the most benefit at the lowest feasible dose, reducing toxicity and expense.

Boosting the enantioresolution of zwitterionic-teicoplanin chiral stationary phases by moving to wide-pore core-shell particles.

A novel zwitterionic-teicoplanin chiral stationary phase (CSP), based on superficially porous particles (SPPs) of 2.7 µm particle diameter and 160 Å pore size, has been prepared and evaluated towards the enantioseparation of important classes of compounds, including chiral drugs, pesticides, and N-derivatized amino acids. The comparison with two analogous CSPs prepared on SPPs with 2.7 and 2.0 µm particle diameter and 90 Å pore size has revealed that the use of large-pore particles allows to dramatically improve both the enantioselectivity and the resolution-per-analysis-time, at the point that the column prepared with the new CSP outperformed the one packed with the finest particles. On the novel wide-pore CSP, the separation of fifteen racemates of pratical importance was significantly improved in terms of both enantioselectivity and resolution-per-analysis time-compared to the CSPs based on SPPs with smaller pores (90 Å). Such a CSP would be suitable for very fast enantioseparations allowing the saving of solvent for greener high-efficiency/high-throughput applications.

Assessing Bone Marrow Activity with [18F]FLT PET in Patients with Essential Thrombocythemia and Prefibrotic Myelofibrosis: A Proof of Concept.

Objectives: This study aims to assess the value of FLT-PET as a non-invasive tool to differentiate between patients with ET and Pre-PMF. This study is a pilot study to have a proof of concept only. Methods: This is a prospective, interventional study where a total of 12 patients were included. Each patient underwent FLT PET imaging as well as bone marrow examination (gold standard). In addition, semi-quantitative (SUVmax and SUVmean) measurements of FLT uptake in the liver, spleen, and Lspine, SUVmean, as well as the Total Lesion Glycolysis (TLG) of the Lspine were performed. Results from the two patient cohorts were compared using = Kruskal-Wallis statistical test. A P-value of <.05 is considered to be statistically significant. Results: The differences in FLT SUVmax and SUVmean measurements in the three organs (liver, spleen, and LSpine) between the ET and Pre-PMF patients were not statistically significant (P > .05). In contrast, TLG measurements in the LSpine were statistically different (P = .013), and therefore, compared to gold standard bone marrow results, TLG can separate ET and Pre-PMF patients. Conclusion: This study is a proof of concept about the potential to discriminate between ET and pre-PMF patients in a non-invasive way. TLG of the LSpine in FLT PET images is a potential quantitative parameter to distinguish between ET and pre-PMF patients.

Investigating Genetic and Other Determinants of First-Onset Myocardial Infarction in Malaysia: Protocol for the Malaysian Acute Vascular Events Risk Study.

BACKGROUND: Although the burden of premature myocardial infarction (MI) is high in Malaysia, direct evidence on the determinants of MI in this multi-ethnic population remains sparse. OBJECTIVE: The Malaysian Acute Vascular Events Risk (MAVERIK) study is a retrospective case-control study established to investigate the genomic, lipid-related, and other determinants of acute MI in Malaysia. In this paper, we report the study protocol and early results. METHODS: By June 2019, we had enrolled approximately 2500 patients with their first MI and 2500 controls without cardiovascular disease, who were frequency-matched by age, sex, and ethnicity, from 17 hospitals in Malaysia. For each participant, serum and whole blood have been collected and stored. Clinical, demographic, and behavioral information has been obtained using a 200-item questionnaire. RESULTS: Tobacco consumption, a history of diabetes, hypertension, markers of visceral adiposity, indicators of lower socioeconomic status, and a family history of coronary disease were more prevalent in cases than in controls. Adjusted (age and sex) logistic regression models for traditional risk factors indicated that current smoking (odds ratio [OR] 4.11, 95% CI 3.56-4.75; P<.001), previous smoking (OR 1.34, 95% CI 1.12-1.60; P=.001), a history of high blood pressure (OR 2.13, 95% CI 1.86-2.44; P<.001), a history of diabetes mellitus (OR 2.72, 95% CI 2.34-3.17; P<.001), a family history of coronary heart disease (OR 1.28, 95% CI 1.07-1.55; P=.009), and obesity (BMI >30 kg/m2; OR 1.19, 95% CI 1.05-1.34; P=.009) were associated with MI in age- and sex-adjusted models. CONCLUSIONS: The MAVERIK study can serve as a useful platform to investigate genetic and other risk factors for MI in an understudied Southeast Asian population. It should help to hasten the discovery of disease-causing pathways and inform regionally appropriate strategies that optimize public health action.

Coexistence of Prefibrotic Myelofibrosis with Monoclonal Gammopathy of Undetermined Significance: A Case Report.

The coexistence of dual hematological neoplasms is an unusual and challenging presentation due to the different combination of etiopathology. The presentation of synchronous dual hematological malignancies can be one of the 3 types: myeloid + lymphoid or dual lymphoid or dual myeloid. Here, we are reporting a case of a 53-year-old male with simultaneous presence of JAK2 V617F-positive myeloproliferative neoplasm with features favoring prefibrotic phase of primary myelofibrosis (pre-PMF) in combination with monoclonal gammopathy of undetermined significance (MGUS). In such cases of simultaneous existence of dual hematological neoplasm management, it is recommended to treat the more aggressive one. Currently, our management plan is focusing on treating the pre-PMF and observation of MGUS with regular monitoring for transformation to MM.

Staggered Dual Kidney Transplantation.

We describe a case where a patient received a successful dual kidney transplantation in a staggered fashion. Two kidneys from a deceased donor were accepted for 2 separate primary intended recipients, however, due to unforeseen circumstances, both kidneys were eventually transplanted in a staggered fashion into an alternate single recipient. The intention behind this method was to enhance the patient's renal function and to prevent the wastage of a kidney. Despite the significantly prolonged cold ischemia times, the recipient has excellent dual graft function after 3 years. The positive outcome underpins the effectiveness of donor kidneys even with prolonged cold ischemia times outside established best practice guidelines. It also reinforces the effectiveness of dual kidney transplantation. Transplant professionals encounter complex situations occasionally where an established evidence-base or aids to decision-making are limited. This case reflects challenges in decision-making, patient counselling and consent, especially when the opportunity for the staggered dual kidney transplantation, with potential increased morbidity, came about as another recipient declined a usable kidney. It also highlights the widely differing risk appetites of different patients. Crucially, it optimised the donation process and procurement of 2 kidneys while preventing wastage. To our knowledge, this is the first report of a staggered dual kidney transplantation in a single recipient.
