RESUMO

Iranian culture and religious teachings lead to a unique value-laden model in health and medical education systems. This research aimed to determine these fundamental values. To identify the health system values in the religious context of Iran, a mixed critical analysis-synthesis method was conducted. Furthermore, a focus group discussion with experts was conducted. Finally, we determined the fundamental values for the Iranian-religious progress model of health care and medical education. God centeredness, spirituality, divine and religious belief, ethical virtues, health centeredness and promoting all dimensions of human health, justice, protecting the human dignity, protecting health-related rights, social accountability, community centeredness, and scientific authority (excellence) are the values that should be considered to complete the value statement of the Iranian-religious progress model of health care and medical education.

RESUMO

PURPOSE: Urinary tract infection (UTI) is the most common bacterial infection among infectious complications in kidney transplant recipients (KTR). After transplantation, infections can result from surgical complications, donor-derived infections, pre-existing recipient infections, and nosocomial infections. Post-transplant infection is still a major cause of morbidity, mortality, graft dysfunction and rejection. In this paper, we aimed to review a few compelling questions in kidney transplantation (KTX). METHODS: To identify relevant clinical questions regarding KTX and UTI a meeting was conducted among physicians involved in the KT program in our hospital. After discussion, several clinically relevant questions related to UTI after KTX. The 5 first rated in importance were judged generalizable to other clinical settings and selected for the purposes of this review. RESULTS: Nearly half of the patients present in the first three months of transplant with UTI. The most common uropathogens in post-transplant UTIs are Escherichia coli, Klebsiella pneumoniae, and Enterococcus faecalis. Risk factors for UTI include female sex, advanced age, recurrent UTI before transplant, prolonged urethral catheterization, delayed graft function, and cadaveric kidney transplant. CONCLUSION: The incidence of post-transplant UTI is similar in both developed and developing countries. E.coli is the most common pathogen in most of studies. Cadaveric donor and post-dialysis transplantation are defined as independent risk factors for post-transplant UTI. Further studies are still required to identify risk factors after kidney transplantation and UTI's importance for graft function and patient outcome.

RESUMO

BACKGROUND: Kidney transplant improves patients' survival and quality of life. Worldwide, concern about the equality of access to the renal transplant wait-list is increasing. In Iran, patients have the choice to be placed on either the living or deceased-donor transplant wait-list. METHODS: This was a prospective study performed on 416 kidney transplant recipients (n = 217 (52.2%) from living donors and n = 199 (47.8%) from deceased donors). Subjects were recruited from four referral kidney transplant centers across Tehran, Iran, during 2016-2017. The primary outcome was to identify the psycho-socioeconomic factors influencing the selection of type of donor (living versus deceased). Secondary objective was to compare the outcomes associated with each type of transplant. The impact of psycho-socioeconomic variables on selecting type of donor was evaluated by using multiple logistic regression and the effect of surgical and non-surgical variables on the early post-transplant creatinine trend was assessed by univariate repeated measure ANOVA. RESULTS: Based on standardized coefficients, the main predictors for selecting living donor were academic educational level (adjusted OR = 3.25, 95% CI: 1.176-9.005, p = 0.023), psychological status based on general health questionnaire (GHQ) (adjusted OR = 2.46, 95% CI: 1.105-5.489, p = 0.028), and lower monthly income (adjusted OR = 2.20, 95% CI: 1.242-3.916, p = 0.007). The waiting time was substantially shorter in patients who received kidneys from living donors (p < 0.001). The early post-transplant creatinine trend was more desirable in recipients of living donors (ß = 0.80, 95% CI: 0.16-1.44, p-value = 0.014), patients with an ICU stay of fewer than five days (ß = - 0.583, 95% CI: - 0.643- -0.522, p-value = < 0.001), and those with less dialysis duration time (ß = 0.016, 95% CI: 0.004-0.028, p-value = 0.012). Post-operative surgical outcomes were not different across the two groups of recipients (p = 0.08), however, medical complications occurred considerably less in the living-donor group (p = 0.04). CONCLUSION: Kidney transplant from living donors was associated with shorter transplant wait-list period and better early outcome, however, inequality of access to living donors was observed. Patients with higher socioeconomic status and higher level of education and those suffering from anxiety and sleep disorders were significantly more likely to select living donors.

RESUMO

Clinical potential of curcumin in radiotherapy (RT) setting is outstanding and of high interest. The main purpose of this randomized controlled trial (RCT) was to assess the beneficial role of nanocurcumin to prevent and/or mitigate radiation-induced proctitis in prostate cancer patients undergoing RT. In this parallel-group study, 64 eligible patients with prostate cancer were randomized to receive either oral nanocurcumin (120 mg/day) or placebo 3 days before and during the RT course. Acute toxicities including proctitis and cystitis were assessed weekly during the treatment and once thereafter using CTCAE v.4.03 grading criteria. Baseline-adjusted hematologic nadirs were also analyzed and compared between the two groups. The patients undergoing definitive RT were followed to evaluate the tumor response. Nanocurcumin was well tolerated. Radiation-induced proctitis was noted in 18/31 (58.1%) of the placebo-treated patients versus 15/33 (45.5%) of nanocurcumin-treated patients (p = 0.313). No significant difference was also found between the two groups with regard to radiation-induced cystitis, duration of radiation toxicities, hematologic nadirs, and tumor response. In conclusion, this RCT was underpowered to indicate the efficacy of nanocurcumin in this clinical setting but could provide a considerable new translational insight to bridge the gap between the laboratory and clinical practice.

RESUMO

BACKGROUND: Defective DNA repair capacity caused by inherited polymorphisms could be associated with cancer susceptibility. One of the major repair pathways is Nucleotide Excision Repair (NER). We investigated Xeroderma Pigmentosum complementation group C (XPC) polymorphisms (Lys939Gln, PAT) with the risk of prostate cancer. METHODS: 154 confirmed prostate cancer patients and 205 Benign Prostate Hyperplasia (BPH) controls were recruited in this survey. The genotypes were determined by PCR-Restriction Fragment Length Polymorphism (RFLP) method. RESULTS: Our results indicated that there were no significant differences between the BPH group and patient group for the XPC Lys939Gln in this pathway. However, deletion/insertion (D/I) and insertion/insertion (I/I) of XPC PAT polymorphism in this pathway could decrease the risk of prostate cancer and act as a protective factor. CONCLUSIONS: In this study, XPC Lys939Gln gene polymorphism was not associated with the risk of developing prostate cancer in Iranian patients. There are no association between different alleles of this polymorphism and grades and stages of tumors, but our results indicated the significant association between XPC PAT and reduction of prostate cancer risk in this group of patients. For more significant results, further samples are required.

RESUMO

Transplant renal artery stenosis is the most common vascular complication that occurs following kidney transplantation and can lead to graft dysfunction and even its loss. The present report describes A patient with endstage renal disease who underwent living related renal transplantation. He had oliguria and creatinine rise in the post-operative course but all doppler ultrasonography (DUS) during the 2 months post-operation for the renal graft showed a normal mean resistive index in the graft renal artery. Hemodialysis treatment started and continued for 4.5 months. On post-operative day 137, because of the patient's anuria and resistant hypertension, another DUS carried out and reported evidence that suggested arterial stenosis. A computed tomographic (CT) renal angiogram showed a small filling defect in the proximal graft artery that was highly suggestive for transplant renal artery stenosis (TRAS). Following angiography revealed a short linear stenosis. Endovascular intervention and stent placement were performed successfully for the patient on post-operative day 139. This case was initially diagnosed as ongoing acute rejection for which he received antirejection therapy without any significant improvement. After percutaneous transluminal angioplasty (PTA), serum creatinine trended down and urine output improved within 12 h, and they were stable at one-year follow up with a good renal function. It was noteworthy that, despite after a 4.5-month delay in diagnosis and maintenance need for dialysis, the patient responded to endovascular treatment and the graft function became normalized. Our case demonstrates that graft can be saved even if renal artery stenosis is diagnosed after several months of dialysis and diagnosis of end stage renal disease post transplantation.

RESUMO

Mixed epithelial and stromal tumor (MEST) of the kidney is not a common diagnosis. This tumor usually mimics solid-cystic malignant renal tumors and most cases are treated surgically. Here, we presented a 35-year-old female with simultaneous two separate large solid-cystic masses with contrast enhancement in lower and upper pole of left kidney which were managed surgically via partial nephrectomy. Microscopic evaluation showed solid-cystic tumor with variably sized cysts lined by flattened to cuboidal epithelium that was compatible with MEST. Follow up evaluation revealed normal parenchymal renal tissue and proper function without any evidence of local recurrence.

RESUMO

OBJECTIVES: This study aimed to investigate the possible role of different donor and recipient vessel and ureteral anastomoses on survival and functional outcomes in en bloc kidney transplants. MATERIALS AND METHODS: This retrospective cohort included 99 en bloc kidney transplants performed from December 2005 to March 2022. Recipients were grouped based on donor's vessel (distal [n = 84] or proximal [n = 15] abdominal aorta), recipient's vessel (abdominal aorta [n = 3], external [n = 21], internal [n = 50], or common [n = 25] iliac artery), and ureteral anastomosis (separate [n = 32] or common [n = 67]). Patient and graft survival, complication rates, and estimated glomerular filtration rate trends were compared between groups. RESULTS: Pediatric brain dead donors had a mean age and weight of 37 ± 22 months and 14 ± 4 kg, respectively. Donor and recipient vessel and ureteral anastomoses did not affect overall survival (P = .306, .296, and .225), graft survival (P = .720, .172, and .124), and vascular (P = .347, .689, and .264) and urinary (P = .587, .172, and .385) complication rates. Lymphoceles requiring intervention were significantly more prevalent in the recipient external iliac artery group (P = .008) but were independent of donor vessel and ureteral anastomosis (P = .587 and 1.00). Estimated glomerular filtration rate trend was independentofdonor(P=.921) andrecipient vessel(P=.878 and .536). CONCLUSIONS: We found that different arterial and ureteral anastomoses appear to have comparable outcomes in en bloc kidney transplant with the exception of recipient external iliac artery, which may be slightly inferior because of the relatively higher rate of lymphoceles requiring intervention.

RESUMO

PURPOSE OF REVIEW: While most renal and ureteral stones can be efficiently managed using endourologic techniques, the use of laparoscopy for the management of urolithiasis is increasing. The application of laparoscopy for stone removal will further reduce the need for open stone surgery. RECENT FINDINGS: Laparoscopic ureterolithotomy, pyelolithotomy, and anatrophic nephrolithotomy are highly successful techniques with regard to their one-session, high stone-free rates. These procedures could be considered as the preferred approaches when endourologic procedures are not available or have failed. Laparoscopic stone surgery (LSS) in patients with urinary tract anomalies offers a reliable minimally invasive procedure as an alternative to a complex endourologic technique. SUMMARY: Although laparoscopy still has a limited role in the urologist's armamentarium for the surgical management of urolithiasis, it can further reduce the need for open stone surgery in complex circumstances. LSS duplicates its open counterpart and offers a high one-session, stone-free rate in most patients with a lower morbidity and quicker convalescence. More comparative studies are needed to define the role and indications of LSS in relation to endourologic and open techniques, especially in complex circumstances.

RESUMO

Background: A 1985 law in the Islamic Republic of Iran integrated all health-related educational institutions into the Ministry of Health and established the Ministry of Health and Medical Education to set policies. Aims: We aimed to classify the value concept of the policies that prioritized and to develop a conceptual value-based framework, for the Islamic Republic of Iran's healthcare and medical education systems. Methods: We conducted this qualitative study using a critical, thematic content analysis of value-based statements and policy documents on health and the development of medical education published from 2009 to 2019 in the Islamic Republic of Iran. A total of 210 documents were reviewed and 7 were critically analysed. Value concepts were identified and coded. Results: A total of 69 value concepts were classified into 28 subthemes and 5 main themes: mission values, principal values, procedural values, implementation values, and outcome values. We identified the pattern of the fundamental values to present our conceptual framework. Conclusion: This comprehensive value-based framework can help establish a supportive value-based culture among policymakers, identify under- and over-emphasized issues, and enhance the incorporation of fundamental values across the health and medical education system.

RESUMO

OBJECTIVES: Although several studies have explored the connection between corticosteroids and renal transplant surgical complications, these studies have overlooked several factors. In addition, no review of the literature, to our knowledge, has been conducted to evaluate corticosteroid dose and incidence of posttransplant surgical complications in these patients. Thus, our objective was to carry out a systematic investigation ofthe correlationbetween corticosteroids and surgical complications in renaltransplant patients. MATERIALS AND METHODS: A systematic search was conducted on the PubMed and Embase databases from their inception until April 2023. Retrospective and prospective cohort studies were included if they met the association between corticosteroids and surgical complications. The search strategy was performed using MeSH and non-MeSH key words. Terms used in the electronic search included kidney transplant* OR kidney transplant(mesh) AND steroid* OR steroids(mesh) AND complication* OR intraoperative complications(mesh). RESULTS: From 3274 articles, 8 articles were included in the systematic review. Six studies were conducted as retrospective cohorts and 2 studies as prospective cohorts. The mean age of patients included in the studies was 42.1 years. The studies were conducted between 1981 and 2023. Findings suggested that decreasing the postoperative corticosteroid dosage was associated with a lower incidence of various postoperative surgical complications. CONCLUSIONS: We investigated the potential benefits of reducing the dose of corticosteroids following kidney transplant. Findings suggested thatreducing the dose of corticosteroids following kidney transplant might be a viable strategy for minimizing the risk of surgical complications. However, it is essential to note that the optimal dosage and duration of corticosteroid therapy after kidney transplant may vary for each patient and should be carefully determined by the health care provider.

RESUMO

PURPOSE: To investigate the impact of reducing post-operative oral corticosteroid regimen on associated postoperative surgical complication rate, patient and graft survival in kidney transplant patients. MATERIALS AND METHODS: In this retrospective cohort study, we enrolled patients who received a kidney transplant during two periods of distinct corticosteroid protocols. 592 patients in group 1 received prednisone 2 mg/kg (maximum dose 120 mg) on post-operative days (POD) 1, 2 and 3, 1mg/kg for a week, and tapered it to 10 mg by 3 months post-transplant and sustained the daily 10mg from 3 months post-transplant as maintenance therapy. 639 patients in group 2 received prednisone 50 mg on POD 1, 40mg on POD 2, 30mg on POD 3, 20mg on POD 4, 15mg on POD 5 and continued with 10mg daily from POD 6, as maintenance therapy. The two groups were similar in terms of other immunosuppression drug regimens. RESULTS: 75 (12.7%) patients in group 1 and 24 (3.4%) patients in group 2 developed corticosteroid-related postoperative surgical complications (P < .001). Wound infection (P = .035), incisional hernia (P = .003), infectious collection (P = .004), post-op hemorrhage (P = .005) and ureteral fistula (P = .076) occurred with lower frequency in group 2. Patient survival (1-year: 97.3% vs 97.1%, respectively; P = .85, 5-year: 89.9% vs 94.9%, respectively; P = .06) and graft survival (1-year: 94.6% vs 93.3%, respectively; P = .29, 5-year: 81.2% vs 85.1%, respectively; P = .39) were similar in both groups. CONCLUSION: Post-operative corticosteroid dosage decrement through our protocol would lessen the serious associated postoperative surgical complications, without negative impacts on overall patient and graft survival.

RESUMO

BACKGROUND: To compare the disease course, histopathological features and survival rates of prostate cancer (PCa) between patients aged ⩽ 55 and > 55 year old. MATERIALS AND METHODS: In this retrospective study, we enrolled 644 patients with organ-confide prostate cancer who had undergone radical prostatectomy from 2005 to 2018. Seventy-six (11.8%) patients were under 55 years of age (group 1) and 568 (88.2%) patients were >55 years old (group 2). RESULTS: Pre-operative hypertension was detected in 4 (5.3%) patients of group 1 and 80 (14.1%) patients of groups 2 (p = 0.029). The mean (±SD) prostate volume was higher in group 2 compared with group 1 (34.1(±8.4) ml vs 54.1(±9.9) ml, p < 0.001). Positive surgery margin was observed in 15 (19.7%) and 58 (10.2%) patients in group 1 and 2, respectively (p = 0.020). Co-existence of diabetes mellitus, mean pre-operative PSA, Gleason's score, and permanent pathology and pathologic stage were similar between the two groups. Log-rank test failed to show any statistical difference in terms of biochemical-relapse free survival, local recurrence-free survival, and metastasis-free survival between the two groups (p = 0.316, 0.441, 0.654, respectively). After performing multivariate analysis, positive surgical margin was the only factor that was independently predictive of biochemical relapse (p < 0.001) and local recurrence/metastasis (p < 0.001). CONCLUSION: No difference was observed in terms of histopathologic features, biochemical relapse, and local recurrence/metastasis-free survival rates between patients younger and older than 55 years of age.

RESUMO

To report our experience with unroofing of ipsilateral lower pole kidney cysts in five patients with adult-type polycystic kidneys [ADPKD] when free implantation of kidney allograft interfered with lower pole native kidney cysts. In all of these patients, the native kidneys extended to the ipsilateral pelvis and bilateral ADPKD caused enlargement of the abdomen on gross examination. Unroofing of lower pole kidney cysts was performed during the same session of allograft transplantation. The decision to unroof lower pole cysts of the ipsilateral kidney was made after observing interference of lower pole cysts with free implantation of the allograft. In patient A, bilateral native nephrectomy was performed 6 weeks after kidney transplantation after consultation with the patient, when there was evidence of the good function of the allograft and the recipient was on a low dose of immunosuppressive medications. In other patients, no need for native nephrectomy observed. This experience suggests the possibility that when large ipsilateral kidney cysts interfere with safe implantation of the allograft, there is an option of performing cyst unroofing at the same session and proceeding with allograft implantation. In many patients, there would be no need for native nephrectomy and of deemed necessary, it will be performed later, when there is evidence of the good function of the allograft and the patient is on good kidney function with a low dose of immunosuppressive medications and a less risk profile for the operation. To our best knowledge, there is no prior such report in the literature.

RESUMO

This study aimed to evaluate the outcomes of laparoscopic pyelolithotomy, including its efficacy and feasibility in treatment of large renal stones. All patients who underwent laparoscopic pyelolithotomy operations in a referral center were enrolled from 2003 to 2020. The final analysis included 436 patients. The total stone free rate was 88.3% and the stone-free rate for staghorn/multiple stones versus other types of stones was 81% vs. 91% (P = 0.002). Likewise, the total operation duration was 158 ± 50 and the operation duration for staghorn/multiple stones versus other types of stones was 171 ± 51 min vs. 153 ± 49 min (P < 0.001). The operation duration (169 ± 51 vs. 155 ± 58 vs. 155 ± 42 min) and hospitalization (4.5 ± 2.3 vs. 4.0 ± 2.2 vs. 3.6 ± 1.8) decreased with increasing the surgeons' experience over time. The outcomes of laparoscopic pyelolithotomy for children versus adults versus geriatric patients and in patients with normal versus abnormal kidney anatomy did not reveal statistically significant differences. Laparoscopic pyelolithotomy could be employed as an alternative surgical approach for patients with large kidney stones of any age or with kidney abnormalities provided that appropriate expertise is available to carry out the procedure.

RESUMO

OBJECTIVE: In this study, we aimed to compare the frequency of lymphoceles that needed intervention in recipients who received kidneys from living versus deceased donors. MATERIALS AND METHODS: The records of all patients who underwent kidney transplantation at the Labbafinejad Hospital from 2012 to 2021 were retrospectively reviewed to determine the incidence of lymphoceles that needed intervention for management. RESULTS: From March 2012 to April 2021, 1752 patients received kidney transplantation in Labbafinejad Hospital including 975 transplantations from living donors and 777 transplantations from deceased donors. Symptomatic lymphoceles were observed postoperatively in 23 patients. Symptoms included compressive effect on the ureter, hydroureteronephrosis of the transplanted kidney, frequency, urinary retention, infection,  abdominal discomfort, or rise in serum creatinine. Out of 23 patients who needed intervention for symptomatic lymphocele, 15 patients were recipients of living donors and 8 patients were recipients of deceased donors [1.53% versus 1.03%, P=.40]. Intervention consisted of open surgical drainage in 6 patients [4 recipients of living donors and 2 recipients of deceased donors], and nephrostomy insertion in 17 patients. Open operation was necessary in 5 (47%) patients in whom arterial anastomosis was made to the internal iliac artery versus 1 (9%) patient in whom the anastomosis was not made to the internal iliac artery (P=0.15). CONCLUSION: Symptomatic lymphoceles which needed intervention were observed in low frequency (1.31%). Most cases can be managed by endoscopic drainage without relapse. Type of donation had no relationship with the need for open or endoscopic intervention in lymphoceles. A higher proportion of open surgeries to control lymphocele were observed in recipients in whom the internal iliac artery was used for arterial anastomosis however the difference was not statistically significant.

RESUMO

PURPOSE: To evaluate oncological outcomes in patient with positive surgical margin (PSM) following partial nephrectomy (PN). MATERIAL AND METHODS: In this retrospective study, we enrolled the data of patients who underwent PN between 2008 and 2017. The inclusion criteria were a definite diagnosis of kidney tumor who underwent PN with at least one year follow up. RESULTS: From the 450 patients who underwent PN, The PSM was found in 35 (22 male/13 female) patients. 18/237 (7.6%) and 17/213 (7.9%) of them were in open and laparoscopic group, respectively. Clear cell RCC was the most prevalent pathology (18 patients) in the PSM patients. The mean time of follow up was 46 ± 2.02 months. Recurrence was developed in 5 (14.2%) patients. There was no correlation between recurrence and sex (p=1.00), surgery type (p = 0.658), age (p = 0.869), tumor size (p = 0.069), pathology (p = 0.258) and stage (p = 0.744) in PSM patients. Recurrence free survival was similar between the open and laparoscopy groups in PSM patients (p = 0.619). CONCLUSION: Beside numerous advantages of minimally invasive techniques, laparoscopic approach would be comparable to conventional open partial nephrectomy in terms of oncologic outcomes. The rate of recurrence following partial nephrectomy in PSM patients is considerable and closely monitoring is mandatory.

RESUMO

Force and position feedback are the two important parameters that are employed in different medical diagnoses and more specifically surgical operations. Furthermore, during different minimally invasive procedures, the ability of touch and force and position feedback are absent. In this regard, artificial palpation is a new technology that is employed to obtain tactile data in situations where physicians/surgeons cannot use their tactile sense. One of the most valuable achievements of artificial palpation are tactile sensory systems that have various applications in the detection of hard objects inside the soft tissue. Considering the present problems and limitations of kidney stone removal laparoscopy, the aim of this research is to design and fabricate a novel tactile sensory system capable of determining the exact location of stones during laparoscopy. This new tactile sensory system consists of four main parts: The sensory part, the mechanical part, the electrical part, and the display part. In this new system, due to the use of both displacement and force sensors, the usage limitations of previous tactile sensory systems are eliminated. The new tactile sensory system is well capable of finding the stone in the laboratory models through physical contact with the model's surface.

RESUMO

BACKGROUND: To study the current trends in Obstetrics-Gynecology (Ob-Gyn) education and workforce in Iran since 1979 and to discuss the consequences and implications. METHODS: This descriptive-analytical study was conducted to describe the Ob-Gyn residency and fellowship growth and workforce profile in Iran (1979-2017).The first-hand data gathered from MOHME and Iran's Medical Council. The Obstetrician-Gynecologist (Ob-Gyns) per 100000 populations' ratio and the percentage changes calculated and the trends analyzed. RESULTS: Between 1979 and 2017, the proportion of trained Ob-Gyns at national universities increased by 86.27%, the number of certified Ob-Gyns increased by 333% and, female Ob-Gyns increased by 1142%.The ratio of active gynecologists per 100,000 people was 5.0 in 1979 and 8.05 in 2017, represents an increase of 70%. Since 1979 the number of active gynecologists has increased by 278 and the number of active female gynecologists has increased by 996%. Since 1990 the maternal mortality per 100,000 live births decreased by 79.9% in Iran. However, since 1980 the Cesarean proportion increased by 203% in Iran. CONCLUSION: Ob-Gyn education has undergone remarkable growth. Ongoing research should focus on Ob-Gyn's geographic distribution, and potential implications of female Ob-Gyns practice pattern and technologies on women's health.

RESUMO

Request for kidney transplantation (K.T.) is increasing rapidly because of the worldwide pandemic of end-stage renal disease, and the most critical issue is organ shortage. The available deceased donors will not resolve the continuing scarcity of organs. It is now professionally and ethically acknowledged and is vital to pay money to the donors for excluding disincentives of living organ donation. Living organ donation should be a vital part of the K.T. Program of any country.
