Surgery is associated with better long-term outcomes than pharmacological treatment for obesity: a systematic review and meta-analysis.

Obesity is a highly prevalent disease with numerous complications. Both intensive medical treatment with the use of pharmacological drugs and bariatric surgery are current options. The objective of this meta-analysis was to compare, in the long-term, intensive medical treatment and surgery based on twelve parameters related to weight loss, cardiovascular and endocrine changes. A review of the literature was conducted in accordance with the PRISMA guidelines (PROSPERO: CRD42021265637). The literature screening was done from inception to October 2023 through PubMed, EMBASE and Web of Science databases. We included randomized clinical trials that had separate groups for medical treatment and bariatric surgery as an intervention for obesity. The risk of bias was assessed through RoB2. A meta-analysis was performed with measures of heterogeneity and publication bias. Subgroup analysis for each surgery type was performed. Data is presented as forest-plots. Reviewers independently identified 6719 articles and 6 papers with a total 427 patients were included. All studies were randomized controlled trials, three had a follow up of 5 years and two had a follow up of 10 years. Both groups demonstrated statistical significance for most parameters studied. Surgery was superior for weight loss (- 22.05 kg [- 28.86; - 15.23), total cholesterol (- 0.88 [- 1.59; - 0.17]), triglycerides (- 0.70 [- 0.82; - 0.59]), HDL (0.12 [0.02; 0.23]), systolic pressure (- 4.49 [- 7.65; - 1.33]), diastolic pressure (- 2.28 [- 4.25; - 0.31]), Hb glycated (- 0.97 [- 1.31; - 0.62]), HOMA IR (- 2.94; [- 3.52; - 2.35]) and cardiovascular risk (- 0.08; [- 0.10; - 0.05]). Patient in the surgical treatment group had better long term outcomes when compared to the non-surgical group for most clinical parameters.

Dynamic evolution of kidney function in patients with STEC-hemolytic uremic syndrome followed for more than 15 years: unexpected changes.

BACKGROUND: Most studies regarding kidney outcomes in patients with Shiga toxin-producing Escherichia coli-hemolytic uremic syndrome (STEC-HUS) focus on kidney status at last assessment. We aimed to describe patterns of changes in kidney function during follow-up and investigate associations between kidney function at 1st, 5th, and 10th year after onset and long-term kidney outcomes. METHODS: Data of patients with STEC-HUS followed for at least 15 years were analyzed. Kidney function patterns were constructed considering kidney status at 1st, 5th, 10th, and ≥ 15 years and defined as (1) progressive, if patients changed from complete recovery to any chronic kidney disease (CKD) stage or if CKD worsened; (2) improvement, if they shifted from any CKD stage to complete recovery or to a milder stage; and (3) stable, if remained unchanged. RESULTS: Of 152 patients included, after 1 year of follow-up, 47% had complete recovery, 22% CKD1, and 32% CKD2-5. At last assessment, 46% had complete recovery, 34% CKD1, and 19% CKD2-5. Despite percentages seeming similar, patients differed: 48% were stable, 27% improved, and 25% worsened. Further, 62% of patients with CKD2-4 in the 1st year normalized their glomerular filtration rate (GFR) thereafter. Comparison of kidney function between 1st, 5th, and 10th year to last assessment shows a stable pattern in 48, 59, and 69% respectively. CONCLUSIONS: Changes in kidney function showed a dynamic and complex behavior, with patients moving from one group to another. Consistently, kidney function neither at the 1st, 5th, or 10th year was representative of final outcome. Unexpectedly, two-thirds of patients with CKD2-4 after 1 year achieved normal eGFR later during follow-up.

Long-Term Satisfaction with Breast Augmentation and Augmentation Mastopexy in the Latin American Population.

OBJECTIVE: The primary objective of this study was to determine the long-term satisfaction levels of women who have undergone breast augmentation and augmentation mastopexy procedures, while identifying the factors influencing patient satisfaction. METHODS: A self-reported retrospective case study design was used to collect data from women with breast implants. The study employed a survey that included demographic information, preoperative diagnosis, implant details, and patient-reported outcomes measured using the Breast-Q Instrument, which evaluates satisfaction with breasts, self-esteem, sexual well-being, and physical symptoms. Statistical analyses were conducted to identify correlations and differences in outcomes between the different variables. RESULTS: The survey was completed by 1022 women from 19 countries, with Chile, Mexico, and Colombia being the most represented. Augmentation was performed on 72.2% of the patients, while 27.7% underwent augmentation mastopexy. Patient satisfaction with breast size and shape varied significantly between the two procedures, with patients undergoing augmentation mastopexy showing less satisfaction. In addition, patients who were unaware of their implant shape or placement reported lower satisfaction scores. The study also found that patient satisfaction decreased over time in the augmentation mastopexy cases and that patients with high body mass index had lower satisfaction. CONCLUSION: Augmentation mastopexy in patients with breast ptosis yields lower satisfaction than augmentation alone. Dissatisfaction escalates with overweight/obesity (BMI), post-surgery time, and misinformation. Implant pocket (pre-vs. subpectoral), shape (round vs. anatomical), and size did not impact satisfaction.

Kidney sequelae in 281 Shiga toxin-producing Escherichia coli-hemolytic uremic syndrome patients after a median follow-up of 12 years.

BACKGROUND: A substantial proportion of patients with Escherichia coli-hemolytic uremic syndrome (STEC-HUS) evolve to chronic kidney disease (CKD). The objectives of this study were to evaluate long-term kidney outcomes and to identify CKD predictors. METHODS: In this single-center retrospective study, long-term outcomes of patients were analyzed according to the presence of complete recovery (CR) or CKD at last visit. Then, they were grouped into favorable (CR + CKD1) or poor (CKD2-5) outcome to compare predictors at diagnosis (sex, age, leukocytes, creatinine, hemoglobin, HUS severity score), dialysis duration, and follow-up time between them. RESULTS: Of 281 patients followed up for a median of 12 years, 139 (49%) had CR, 104 (37%) CKD1, 27 (10%) CKD2-4, and 11 (4%) CKD5. Thirty-eight patients progressed to CKD2-5 after a median of 4.8 years, 7% in the first 5 years, increasing to 8%, 10%, and 14% after 5-10 years, 10-15 years, and > 15 years, respectively. They were younger, had higher baseline hemoglobin and leukocytes, and required longer dialysis and follow-up than those with favorable outcome. By multivariate analysis, days of dialysis and follow-up time remained as independent predictors of poor outcome. The best cutoff for days of dialysis was 10 days. After 5 years, 20% of those dialyzed ≥ 10 days evolved to CKD2-5 versus 1% of those non-dialyzed or dialyzed < 10 days. CONCLUSIONS: Fifty-one percent of patients evolved to CKD after 12 years of follow-up and 14% to CKD2-5. Ten days of dialysis was the best cutoff to recognize outcomes. In some cases, kidney damage was evident after 15 years of surveillance, highlighting the need for follow-up until adulthood in all STEC-HUS patients.

Long-Term Pediatric Outcomes of Decompressive Craniectomy after Severe Traumatic Brain Injury.

OBJECTIVE: There is no consensus on the use of decompressive craniectomy (DC) to manage severe traumatic brain injury (sTBI). We evaluated the profile of pediatric patients admitted with sTBI and assessed functional outcomes, 6 months posttrauma, in patients who had a DC and in those who had not, and the functional outcomes of early versus late DCs. PATIENTS AND METHODS: This case-control observational study evaluated pediatric patients admitted for sTBI in Puerto Rico (June 2016-October 2018); we included patients admitted within 24 hours of injury and had a Glasgow Coma Scale (GCS) of 8 or lower. 6-month post trauma outcomes were measured with the Glasgow Outcome Scale Extended Pediatric (GOS-E Peds). RESULTS: 20 patients were included; 15 underwent a DC and 5 comprised the control group. We found no differences in terms of sex, age, GCS score, Pediatric Risk of Mortality score, or Pediatric Trauma Score. However, in the DC group, a higher percentage of patients presented significant cerebral herniation in the initial computed tomography scan (CT) (DC: 73%; control: 0%; P = .005). No differences were found regarding intracranial pressure (ICP), cerebral perfusion pressure, mean arterial pressure, PaCO2, or temperature. Patients in the DC group had longer hospital stay (DC: 41; control: 17 days; P = .0005). All patients with DC survived, with an early procedure being associated with favorable outcomes. CONCLUSION: As determined 6 months post-trauma, this study showed that early DC increased survival and improved functionality.

Case report: Insulinomatosis: description of four sporadic cases and review of the literature.

The best-known etiologies of hyperinsulinemic hypoglycemia are insulinoma, non-insulinoma pancreatogenous hypoglycemic syndrome, autoimmune processes, and factitious hypoglycemia. In 2009, a disease not associated with classic genetic syndromes and characterized by the presence of multiple pancreatic lesions was described and named insulinomatosis. We present the clinical and pathologic features of four patients with the diagnosis of insulinomatosis, aggregated new clinical data, reviewed extensively the literature, and illustrated the nature and evolution of this recently recognized disease. One of our patients had isolated (without fasting hypoglycemia) postprandial hypoglycemia, an occurrence not previously reported in the literature. Furthermore, we reported the second case presenting malignant disease. All of them had persistent/recurrent hypoglycemia after the first surgery even with pathology confirming the presence of a positive insulin neuroendocrine tumor. In the literature review, 27 sporadic insulinomatosis cases were compiled. All of them had episodes of fasting hypoglycemia except one of our patients. Only two patients had malignant disease, and one of them was from our series. The suspicion of insulinomatosis can be raised before surgery in patients without genetic syndromes, with multiple tumors in the topographic investigation and in those who had persistent or recurrent hypoglycemia after surgical removal of one or more tumors. The definitive diagnosis is established by histology and immunohistochemistry and requires examination of the "macroscopically normal pancreas." Our case series reinforces the marked predominance in women, the high frequency of recurrent hypoglycemia, and consequently, a definitive poor response to the usual surgical treatment.

Long-Term Outcome of Temporal Lobe Epilepsy Surgery in 621 Patients With Hippocampal Sclerosis: Clinical and Surgical Prognostic Factors.

Temporal lobe epilepsy (TLE) is the most common type of focal epilepsy and is frequently drug-resistant (DR) to antiseizure medication (ASM), corresponding to approximately one-third of the cases. When left inadequately treated, it can worsen the quality of life, cognitive deficits, and risk of death. The standard treatment for drug-resistant TLE is the surgical removal of the structures involved, with good long-term outcome rates of 60-70 % and a low rate of adverse effects. The goal of successful treatment is sustained seizure freedom. In our study, we evaluated sustained long-term (up to 23 years) surgical outcomes in 621 patients with DR-TLE associated with hippocampal sclerosis, who underwent a temporal lobectomy. We analyzed the main predictive factors that influence the surgical outcome related to seizure control, through a longitudinal and retrospective study, using a multivariable regression model. We found that 73.6% of the patients were free from disabling seizures (Engel Class I), maintained over time in 65% of patients followed up to 23 years after surgery. We found that four independent variables predicted seizure outcomes. The presence of dysmnesic and olfactory aura predicted a less favorable outcome. The history of febrile seizure and the surgical technique predicted a good outcome. Regarding the type of surgical technique, the standard anteromesial temporal lobectomy (ATL) led to significantly better outcomes (78.6% Engel Class I) when compared to the selective amygdalohippocampectomy via subtemporal approach (67.2% Engel Class I; p = 0.002), suggesting that the neuronal networks involved in the epileptogenic zone may be beyond mesial temporal structures. The multivariable regression model with the above-mentioned predictor variables revealed an ExpB = 3.627 (N = 621, p < 0.001), indicating that the model was able to distinguish between patients with a seizure-free. We conclude that epilepsy surgery is a safe procedure, with low rates of postoperative complications and good long-term results.

Progressive neuropathy in patients with lepromatous leprosy after multidrug therapy

BACKGROUND The lepromatous pole is a stigmatising prototype for patients with leprosy. Generally, these patients have little or no symptoms of peripheral nerve involvement at the time of their diagnosis. However, signs of advanced peripheral neuropathy would be visible during the initial neurological evaluation and could worsen during and after multidrug therapy (MDT). Disabilities caused by peripheral nerve injuries greatly affect these patients' lives, and the pathophysiological mechanisms underlying nerve damage remain unclear. OBJECTIVES To evaluate the outcome of peripheral neuropathy in patients with lepromatous leprosy (LL) and persistent neuropathic symptoms years after completing MDT. METHODS We evaluated the medical records of 14 patients with LL who underwent nerve biopsies due to worsening neuropathy at least four years after MDT. FINDINGS Neuropathic pain developed in 64.3% of the patients, and a neurological examination showed that most patients had alterations in the medium- and large-caliber fibers at the beginning of treatment. Neurological symptoms and signs deteriorated despite complete MDT and prednisone or thalidomide use for years. Nerve conduction studies showed that sensory nerves were the most affected. MAIN CONCLUSIONS Patients with LL can develop progressive peripheral neuropathy, which continues to develop even when they are on long-term anti-inflammatory and immunosuppressive therapy.

The importance of transition from pediatric to adult rheumatology care in juvenile idiopathic arthritis.

Introduction: Juvenile idiopathic arthritis (JIA) is the most common rheumatic inflammatory condition in childhood. The long-term morbidity, mortality, and quality of life have improved with the earlier use of disease-modifying drugs (DMARDs) and the availability of biology disease-modifying drugs (bDMARDs). Despite the improvement of treatment, around 50% of the patients reach adulthood with articular and/or extra articular disease activity. A careful planned transition from pediatric to adult care is necessary to reduce the loss of follow-up that is associated with stopping medications, flares, and disability due to untreated arthritis or uveitis.Areas covered: This narrative review provides an overview of the importance of transition in JIA Articles were selected from Pubmed searches.Expert opinion: JIA patients, family, and healthcare workers have to be trained to provide an effective transition plan, based on local and national policies. Important aspects such as expectations, maturation, disease characteristics, disease activity, adherence, disability, and psychological aspects among others have to be considered and addressed during the transition phase to improve self-esteem, self-assurance, and quality of life.

No mesh versus mesh in the treatment of anterior vaginal wall prolapse: prospective, randomised, controlled trial, long-term follow-up.

OBJECTIVES: To compare the efficacy and safety of anterior colporrhaphy (AC) versus transvaginal polypropylene mesh (PM) for the treatment of anterior vaginal wall prolapse (AVWP) at long-term follow-up. METHODS: Prospective and randomized controlled trial, 100 women with AVWP stage ≥ II assessed by the Pelvic Organ Prolapse Quantification System (POP-Q) underwent AC (control group) or PM insertion (mesh group). At baseline and at 60-month follow-up, safety profile, anatomical outcomes by POP-Q measurements and staging, subjective outcomes and quality of life (QoL) impact by ICIQ (SF and VV) and OAB-V8 questionnaires were assessed RESULTS: 76 women completed the study, 43 in Control versus 33 in Mesh group. Significant improvements were observed in all variables between the 2 times in each group (p < 0.0001), without differences between groups. Objective cure (POP-Q Ba ≤ - 2 and Ba ≤ - 1) occurred in 22 and 36 (51.2 and 83.7%) versus 23 and 31 (69.7 and 93.9%), p = 0.10 and 0.29; and subjective cure (VSS, no vaginal symptom) in 21 (48.8%) versus 17 (51.5%), p = 0.82, respectively, at 60-month follow-up. When adjusted for the other variables, Mesh group showed worse QoL impact due to subjective vaginal symptoms (odds ratio 3.99, CI 95% 1.13; 14.13). AVW asymptomatic mesh exposure occurred in 2 patients (6.06%) in the Mesh group. CONCLUSIONS: AC and PM provided good overall objective and subjective outcomes for a minimum 60-month follow-up. Vaginal and urinary symptoms improved post-operatively in both groups. Mesh group experienced four times more negative impact on QoL compared to Control at 60-month follow-up.

Late-Onset Circulatory Collapse and Risk of Cerebral Palsy in Extremely Preterm Infants.

OBJECTIVE: To investigate whether the development of postnatal, late-onset refractory hypotension, referred to as late-onset circulatory collapse, was associated with an increased risk of developing cerebral palsy (CP) at 3 years of age in extremely preterm infants. METHODS: In this historical cohort study, infants who were born at 22-27 weeks of gestation from 2008 to 2012 in the Neonatal Research Network of Japan were eligible. The study sample consisted of 3474 infants (45.6% of 7613 potentially eligible infants) who were evaluated at 36-42 months of age. Late-onset circulatory collapse was defined as a clinical diagnosis of late-onset circulatory collapse requiring treatment with corticosteroids. We compared the neurodevelopmental outcomes between infants with and without late-onset circulatory collapse. RESULTS: Late-onset circulatory collapse was diagnosed in 666 of the infants studied. Infants with late-onset circulatory collapse had a higher incidence of CP than those without late-onset circulatory collapse (18.0% vs 9.8%; P < .01). In multivariable logistic analysis, late-onset circulatory collapse was independently associated with CP (aOR, 1.52; 95% CI, 1.13-2.04) and developmental quotient score of <50 (OR, 1.83; 95% CI, 1.23-2.72). CONCLUSIONS: Late-onset circulatory collapse may be a relatively common event occurring in extremely preterm infants and an independent risk factor for CP at 3 years of age.

Natural history of longitudinally extensive transverse myelitis in 35 Hispanic patients with systemic lupus erythematosus: good short-term functional outcome and paradoxical increase in long-term mortality.

Background and objective Acute transverse myelitis (TM) is an infrequent neurological complication of systemic lupus erythematosus (SLE). Short-term outcome varies widely between cohorts. Little is known about the epidemiology and long-term functional outcome of TM associated to SLE. Methods Patients with SLE and acute TM were identified during hospital admission, visits to the Emergency Room or the Neurology Outpatient Clinic. We evaluated ambispectively those patients with SLE presenting with clinical myelopathy and corroborated with spinal MRI. Cases were divided as partial (non-paralyzing) or complete (paralyzing). We determined long-term functional outcome as well as mortality in those patients with follow-up periods of at least five years. Results We identified 35 patients (partial, n = 15; complete, n = 20) in which complete clinical and imaging data were available (26 with follow-up ≥ 5 years). Patients with complete TM were significantly older than those with partial forms. Positive antiphospholipid antibodies were observed in 80% of patients, suggesting a possible mechanistical role. Surprisingly, functional recovery at one year was in general good; however, we observed a five-year mortality of 31% because of sepsis (in 10 cases) or pulmonary embolism (in one case). Conclusions Short-term outcome of SLE-related TM is generally good, and recurrence rate is low. However, we observed a long-term fatality rate of 31% for reasons unrelated to TM, suggesting that TM is a manifestation of severe immune dysregulation and a predictor of severity and mortality in patients with SLE.

Initial Right Ventricular Dysfunction Severity Identifies Severe Peripartum Cardiomyopathy Phenotype With Worse Early and Overall Outcomes: A 24-Year Cohort Study.

BACKGROUND: Outcomes in peripartum cardiomyopathy (PPCM) vary. We sought to determine whether severity of left or right ventricular dysfunction (RVD) at PPCM diagnosis differentially associates with adverse outcomes. METHODS AND RESULTS: We conducted a single-center retrospective cohort study of 53 patients with PPCM. The primary outcome was a composite of left ventricular assist device implantation, cardiac transplantation, or death. We used Kaplan-Meier curves to examine event-free survival and Cox proportional hazards models to examine associations of left ventricular (LV) ejection fraction <30%, LV end-diastolic diameter ≥60 mm, and moderate-to-severe RVD at PPCM diagnosis with the primary outcome. Median (interquartile range) follow-up time was 3.6 (1.4-7.3) years. Seventeen patients (32%) experienced the primary outcome, of whom 11 had moderate-to-severe RVD at time of PPCM diagnosis. Overall event-free survival differed by initial RVD severity and LV ejection fraction <30%, but not by LV end-diastolic diameter ≥60 mm. In univariable analyses, LV ejection fraction <30% and moderate-to-severe RVD were associated with the outcome (hazard ratios [95% confidence intervals] of 4.85 [1.11-21.3] and 4.26 [1.47-11.6], respectively). In a multivariable model with LV ejection fraction <30%, LV end-diastolic diameter ≥60 mm, and moderate-to-severe RVD, only moderate-to-severe RVD was independently associated with the outcome (hazard ratio [95% confidence interval], 3.21 [1.13-9.10]). Although most outcomes occurred within the first year, nearly a third occurred years after PPCM diagnosis. CONCLUSIONS: Initial moderate-to-severe RVD is associated with a more advanced cardiomyopathy phenotype and increased risk of adverse outcomes in PPCM, within and beyond the first year of diagnosis. By identifying a worse PPCM phenotype, initial moderate-to-severe RVD may prompt earlier consideration of advanced heart replacement therapies.

Long-term evolution after in-hospital cardiac arrest in children: Prospective multicenter multinational study.

OBJECTIVE: The main objective was to study survival and neurologic evolution of children who suffered in-hospital pediatric cardiac arrest (CA). The secondary objective was to analyze the influence of risk factors on the long term outcome after CA. METHODS: prospective, international, observational, multicentric study in 48 hospitals of 12 countries. CA in children between 1 month and 18 years were analyzed using the Utstein template. Survival and neurological state measured by Pediatric Cerebral Performance Category (PCPC) scale one year after hospital discharge was evaluated. RESULTS: 502 patients with in-hospital CA were evaluated. 197 of them (39.2%) survived to hospital discharge. PCPC at hospital discharge was available in 156 of survivors (79.2%). 76.9% had good neurologic state (PCPC 1-2) and 23.1% poor PCPC values (3-6). One year after cardiac arrest we could obtain data from 144 patients (28.6%). PCPC was available in 116 patients. 88 (75.9%) had a good neurologic evaluation and 28 (24.1%) a poor one. A neurological deterioration evaluated by PCPC scale was observed in 40 patients (7.9%). One year after cardiac arrest PCPC scores compared to hospital discharge had worsen in 7 patients (6%), remained constant in 103 patients (88.8%) and had improved in 6 patients (5.2%). CONCLUSION: Survival one year after cardiac arrest in children after in-hospital cardiac arrest is high. Neurologic outcome of these children a year after cardiac arrest is mostly the same as after hospital discharge. The factors associated with a worst long-term neurological outcome are the etiology of arrest being a traumatic or neurologic illness, and the persistency of higher lactic acid values 24h after ROSC. A standardised basic protocol even practicable for lower developed countries would be a first step for the new multicenter studies.

Antiviral treatment for chronic hepatitis B in renal transplant patients.

Chronic hepatitis B infection is frequent in renal transplant patients. It negatively impacts long term outcomes reducing graft and patient survival. Current guidelines clearly define who needs treatment, when to start, what is the first line therapy, how to monitor treatment response, when to stop, and how patients must be controlled for its safety. There is some data showing a favorable safety and efficacy profile of nucleos(t)ide analogue (NUC) treatment in the renal transplant setting. Entecavir, a drug without major signs of nephrotoxicity, appears to be the first option for NUC naïve patients and tenofovir remains the preferred choice for patients with previous resistance to lamivudine or any other NUC. Renal transplant recipients under antiHBV therapy should be monitored for its efficacy against HBV but also for its safety with a close renal monitoring. Studies including a large number of patients with long term treatment and follow up are still needed to better demonstrate the safety and efficacy of newer NUCs in this population.

We divided the lesions into two groups, partial lesions, 9 cases, and complete lesions, 67 cases divided into 3 sub groups: small and medium lesions (< 3 cm), large (3-5 cm) and massive (> 5 cm). Results: after a mean follow-up of 81 months ninety-five percent of patients had good to excellent results with Constant score, 65 ptes excellent (85%), 8 good (10%) and 3 regular (5%) no poor result. With ASES score and SST also observed significant and persistent improvement during follow-up, demonstrating with Wilcoxon test an extremely significant p=0.0001. All Partial lesions have excellent and good results, Applying Mann Whitney test we obtained a P <0.05 in all three scores. In Complete lesions the Constant Score was 95% of good to excellent results at 81 months average follow up. The distribution was: Excellent 65 cases (85%), 8 good (10%), 3 regular (5%) and no poor results. With SST and ASES score we had a significant and persistent improvement in long-term follow up. Being demonstrated with the Wilcoxon test that the difference was highly significant with a P value 0.0001 in the three evaluated functional scores. Discussion: we had statistically significant results when comparing different functional scores of ASES, SST and Constant between surgical pre preoperative score and the long-term follow up with 95% good to excellent results in arthroscopic repair of different rotator cuff lesions. Level of evidence: IV. Type of Study: Therapeutic Study. Cases Series(AU)

Glucocorticoid resistance in dialysis patients reduces long-term graft survival after kidney transplantation.

Glucocorticoid (GC) resistance has been observed in chronic kidney disease (CKD) patients on dialysis. It can be evaluated by binding assays based on the dissociation constant (Kd), which is inversely proportional to ligand affinity. CKD patients with GC resistance had increased number of acute rejection episodes. We followed up 26 patients that underwent kidney transplantation to observe whether GC resistance could affect the response to acute rejection episode pulse therapy and the long-term allograft outcome. Using Kaplan-Meier survival curve, GC resistant patients showed lower acute rejection-free survival (p=0.03) and lower kidney allograft survival (p=0.008). No difference was found regarding number of deaths. Multivariate logistic regression showed that high Kd value was an independent predictor of lower kidney allograft survival (p=0.001). There was a negative Spearman correlation between Kd and kidney allograft survival (r=-0.88, p=0.03). In conclusion, our findings indicate the usefulness of binding assay performed previously to kidney transplantation to define GC resistance. In addition, the dissociation constant (Kd) is a reliable and independent predictive marker of higher frequency of acute rejection episodes, lower rejection-free graft survival, poor response of acute rejection episodes to methylprednisolone pulse therapy, and lower kidney allograft survival in a long-term follow-up.

Tratamiento laparoscópico del cáncer de recto: resultados oncológicos a largo plazo / Laparoscopic treatment of rectal cancer: long-term results

Antecedentes: Si bien la factibilidad del tratamiento laparoscópico del cáncer de recto ha sido previamente descripta, su aplicación masiva continúa siendo controversial y los resultados oncológicos a largo plazo son aun limitados.Objetivo: Analizar los resultados peri operatorios, la tasa de recurrencia local y la sobrevida alejada a cinco años en pacientes con cáncer de recto operados por vía laparoscópica, y comparar la sobrevida de los pacientes operados por vía laparoscópica con la de aquellos que debieron ser convertidos.Diseño: Observacional retrospectivoLugar de aplicación: Hospital Privado UniversitarioMétodo: Se analizaron 164 pacientes portadores de cáncer de recto operados por vía laparoscópica pura entre enero de 2005 y diciembre de 2011. Los datos clínicos, anatomopatológicos y oncológicos, fueron ingresados prospectivamente en una base de datos. La supervivencia global y libre de enfermedad a 5 años fue calculada según el método actuarial de Kaplan-Meier.Resultados: El 66% de la población presentó tumores de recto medio (n=76) e inferior (n=32), y el 26% (n= 43) recibió tratamiento neoadyuvante. La tasa de preservación esfinteriana fue del 95%. La mediana de la altura de la anastomosis fue de 5 cm (rango: 2 a 12), empleando un reservorio colónico en "J" en el 8,5%. El índice de conversión global fue del 14,6%. La morbilidad y mortalidad global fue 19,5% y 0% respectivamente. La mediana de estadía hospitalaria fue 3 días (r: 2-28). No se registró compromiso de los márgenes quirúrgicos. La media de ganglios linfáticos analizados fue de 15 (rango: 0 - 56). La distribución por estadíos de acuerdo al TNM fue del 3,8% para el estadío 0, 37,8% para el estadío I, 22,5% para el estadío II, 29,2% para el estadío III y 6,7% para el estadío IV. El seguimiento promedio fue de 25 meses (rango: 3 a 81). La tasa de recurrencia local de la serie fue del 1,2% (dos pacientes)...

Background: Even though the laparoscopic approach for rectal cancer has been previously described, its extended application is still controversial and the long-term oncological results are limited.Objective: To analyze the surgical results, local recurrence rate and 5-year survival in patients with rectal cancer operated on by laparoscopy. Secondarily, to compare the survival of patients operated on by laparoscopy with those who required conversion to open surgery.Setting: Private University Hospital Design: Retrospective observational.Material and Methods: One hundred and sixty four consecutive patients undergoing laparoscopic surgery for rectal cancer were analyzed between January 2005 and December 2011. The clinical, pathological and oncological data were collected into a database. Overall and disease free survival at 5 years was estimated by Kaplan-Meier method.Results: 66% of patients had tumors in middle (n=76) and low (n=32) rectum, and 26% (n=43) received neoadjuvant therapy. The sphincter preservation rate was 95%. The median distance between the anastomosis and the anal verge was 5 cm (range: 2 - 12), and a "j" pouch was performed in 8.5%. The overall conversion rate to open surgery was 14.6%. The morbidity and mortality was 19.5% and 0% respectively. The median hospital stay was 3 days (range: 2-28). Surgical margins were negative. The median of lymph nodes harvested was 15 (range: 0-56). According to TNM staging, there were 3.8% for stage 0, 37.8 for stage I, 22.5% for stage II, 29,2% for stage III and 6.7 for stage IV. The median follow up time was 25 months (range: 3-81). The overall local recurrence rate was 1.2% (two patients)...
