Influence of Migration on Tuberculosis in a Semi-Urban Area

AimsTo describe the epidemiology of tuberculosis and analyzing the differences among native and immigrant patients in Area III of the Region of Murcia.MethodsCohort study of tuberculosis cases reported to the Epidemiological Surveillance Service from 2004 to 2009. Data collection was performed through the System of Notification Diseases, reviewing clinical files and epidemiological surveys.ResultsOne hundred and sixty two cases were detected; 110 (67.9%) were immigrants, whose incidence rates ranged from 43.4 to 101.2 cases per 100 000 inhabitants. Ecuador (42.7%), Bolivia (30%) and Morocco (18.2%) were the main nationalities.Immigrants were younger than Spanish population (P<.001). The overall diagnostic delay was 50.5 days: 59.5 in Spanish and 47 in foreigners. Moroccans had higher proportions of extrapulmonary TB (P=.02). Mainly, immigrant population took treatment with four drugs (P<.001). Natives had better treatment adherence (P=.04). Spanish cases of tuberculosis were associated with smoking (P<.001), the same as alcohol consumption (P=.01) and injection drug use (P<.001), nevertheless in the foreign-born population the most relevant risk factor was overcrowding (P<.001).ConclusionsThe incidence of tuberculosis rates are higher among immigrant population, where the main risk factor is overcrowding. In contrast, Spanish cases are associated with toxic substances consumption and increasing age.     

Geriatric Assessment and Prognostic Factors of Mortality in Very Elderly Patients With Community-Acquired Pneumonia

IntroductionTo assess the relationship between the parameters obtained in the geriatric assessment and mortality in elderly people with community-acquired pneumonia in an acute care geriatric unit.MethodsFour hundred fifty-six patients (≥75 years). Variables: age, sex, referral source, background, consciousness level, heart rate, breathing rate, blood pressure, laboratory data, pleural effusion, multilobar infiltrates, functional status (activities of daily living) prior to admission [Lawton index (LI), Barthel index (BIp)] prior to and at admission (BIa), cognitive status [Pfeiffer test (PT)], comorbidity [Charlson index (ChI)] and nutrition (total protein, albumin).ResultsA hundred ten patients died (24.2%) during hospitalization. These patients were older (86.6±6.4 vs 85.1±6.4, P<.04), had more comorbidity (ChI 2.35±1.61 vs 2.08±1.38; P<.083), worse functional impairment [(LI: 0.49±1.15 vs 1.45±2.32, P<.001) (BIp: 34.6±32.9 vs 54.0±34.1, P<.001) (BIa: 5.79±12.5 vs 20.5±22.9, P<.001)], a higher percentage of functional loss at admission (85.9±23.2 vs 66.4±28.6; P<.0001), worse cognitive impairment (PT: 7.20±3.73 vs 5.10±3.69, P<.001) and malnutrition (albumin 2.67±0.54 vs 2.99±0.49, P<.001). Mortality was higher with impaired consciousness [49.2% (P<.01)], tachypnea [33.3% (P<.01)], tachycardia [44.4% (P<.002), high urea levels [31.8 (P<.001)], anemia [44.7% (P<.02)], pleural effusion [42.9% (P<.002)], and multilobar infiltrates [43.2% (P<.001)]. In the multivariate analysis, variables associated with mortality were: age≥90 years [OR: 3.11 (95% CI: 1.31–7.36)], impaired consciousness [3.19 (1.66–6.15)], hematocrit<30% [2.87 (1.19–6.94)], pleural effusion [3.77 (1.69–8.39)] and multilobar infiltrates [2.76 (1.48–5.16)]. Female sex and a preserved functional status prior (LI≥5) and during admission (BIa≥40) were protective of mortality [0.40 (0.22–0.70), 0.09 (0.01–0.81) and 0.11 (0.02–0.51)].ConclusionsGeriatric assessment parameters and routine clinical variables were associated with mortality.     

Mortality Analysis of Patients Undergoing Lung Transplantation for Emphysema

BackgroundThe outcomes of lung transplantation 11 years after starting the transplantation program in our hospital are presented. Risk factors associated with short-, medium-, and long-term mortality in transplant recipients were analyzed.Patients and MethodsAll patients diagnosed with emphysema who underwent lung transplantation between March 1997 and June 2008 were included. The association between different study variables and early death and death at 1 year and 5 years was studied. The Kaplan-Meier method was used to analyze survival. A logistic regression model was used to study the association between early death and variables with a trend towards significance (P<.2) in the univariate analysis. The risk factors for mortality at 1 year and 5 years were analyzed by a Cox regression model.ResultsA total of 92 patients were included. Survival was 89.3%, 70%, and 54% at 1 month, 1 year, and 5 years after transplantation, respectively. Dehiscence of the surgical suture (P<.001), duration of mechanical ventilation in the intensive care unit (P=.04), duration of the surgical procedure (P<.001), and single-lung transplantation (P=.007) were the variables associated with mortality. Extracorporeal circulation and the need for hemodiafiltration in the intensive care unit increased the short-term risk of death (P<.05). The age of the recipient was the variable associated with long-term mortality (P=.02). The duration of the surgical intervention was associated with an increase in short-, medium-, and long-term mortality.ConclusionsComplications were responsible for short-term mortality, while age of the recipient was the most important factor in determining long-term survival. Mortality was higher in single-lung transplant recipients compared to double-lung transplant recipients.     

Características,evolución clínica y factores asociados a la mortalidad en UCI de los pacientes críticos infectados por SARS-CoV-2 en España: estudio prospectivo,de cohorte y multicéntrico

BackgroundThe clinical course of COVID-19 critically ill patients, during their admission in the intensive care unit (UCI), including medical and infectious complications and support therapies, as well as their association with in-ICU mortality has not been fully reported.ObjectiveThis study aimed to describe clinical characteristics and clinical course of ICU COVID-19 patients, and to determine risk factors for ICU mortality of COVID-19 patients.MethodsProspective, multicentre, cohort study that enrolled critically ill COVID-19 patients admitted into 30 ICUs from Spain and Andorra. Consecutive patients from March 12^th to May 26^th, 2020 were enrolled if they had died or were discharged from ICU during the study period. Demographics, symptoms, vital signs, laboratory markers, supportive therapies, pharmacological treatments, medical and infectious complications were reported and compared between deceased and discharged patients.ResultsA total of 663 patients were included. Overall ICU mortality was 31% (203 patients). At ICU admission non-survivors were more hypoxemic [SpO₂ with non-rebreather mask, 90 (IQR 83 to 93) vs. 91 (IQR 87 to 94); P<.001] and with higher sequential organ failure assessment score [SOFA, 7 (IQR 5 to 9) vs. 4 (IQR 3 to 7); P<.001]. Complications were more frequent in non-survivors: acute respiratory distress syndrome (ARDS) (95% vs. 89%; P=.009), acute kidney injury (AKI) (58% vs. 24%; P<10^-16), shock (42% vs. 14%; P<10^-13), and arrhythmias (24% vs. 11%; P<10^-4). Respiratory super-infection, bloodstream infection and septic shock were higher in non-survivors (33% vs. 25%; P=.03, 33% vs. 23%; P=.01 and 15% vs. 3%, P=10^-7), respectively. The multivariable regression model showed that age was associated with mortality, with every year increasing risk-of-death by 1% (95%CI: 1 to 10, P=.014). Each 5-point increase in APACHE II independently predicted mortality [OR: 1.508 (1.081, 2.104), P=.015]. Patients with AKI [OR: 2.468 (1.628, 3.741), P<10^-4)], cardiac arrest [OR: 11.099 (3.389, 36.353), P=.0001], and septic shock [OR: 3.224 (1.486, 6.994), P=.002] had an increased risk-of-death.ConclusionsOlder COVID-19 patients with higher APACHE II scores on admission, those who developed AKI grades ii or iii and/or septic shock during ICU stay had an increased risk-of-death. ICU mortality was 31%.     

Experience and Development of the Video-Assisted Thoracic Surgery Lobectomy Technique: Comparative Study With Conventional Surgery in Stage I Non-Small Cell Lung Cancer

BackgroundSurgical treatment of stage I non-small cell lung cancer (NSCLC) can be performed either by thoracotomy or by employing video-assisted thoracic surgery (VATS). The aim of this study was to compare long- and short-term results of conventional surgery (CS) vs VATS lobectomy in the treatment of stage I NSCLC.Materials and methodsWe performed a retrospective, analytical study of patients undergoing surgery for stage I NSCLC during the period January 1993 to December 2005. The variables analysed were overall survival, recurrence, distant metastasis, morbidity, mortality and hospital stay. During this period, 256 anatomic lung resections were performed: 141 by CS and 115 by VATS.ResultsThere were statistically significant differences in: (i) mean hospital stay in patients with no complications (VATS group: 4.3 days vs CS group: 8.7 days, P=.0001); (ii) mean hospital stay in patients with complications (VATS: 7.2 days vs CS: 13.7 days, P=.0001), and (iii) morbidity (VATS: 15.6% vs CS: 36.52%, P=.0001). No statistically significant differences were found in: (i) mortality (VATS: 2.17% vs CS: 1.7%, P=.88); (ii) 5-year overall survival (VATS: 68.1% vs CS: 63.8%), and (iii) local recurrence and distant metastasis (P=.82).ConclusionsVATS lobectomy is a safe and effective approach, with a shorter hospital stay and lower morbidity than CS; no statistically significant differences were observed in survival in patients undergoing surgery for stage I NSCLC.     

Early and late cardiovascular events in patients hospitalized for community-acquired pneumonia

IntroductionCommunity-acquired pneumonia increases the risk of cardiovascular events (CVE). The objective of this study was to analyze host, severity, and etiology factors associated with the appearance of early and late events and their impact on mortality.MethodProspective multicenter cohort study in patients hospitalized for pneumonia. CVE and mortality rates were collected at admission, 30-day follow-up (early events), and one-year follow-up (late events).ResultsIn total, 202 of 1967 (10.42%) patients presented early CVE and 122 (6.64%) late events; 16% of 1-year mortality was attributed to cardiovascular disease. The host risk factors related to cardiovascular complications were: age ≥ 65 years, smoking, and chronic heart disease. Alcohol abuse was a risk factor for early events, whereas obesity, hypertension, and chronic renal failure were related to late events. Severe sepsis and Pneumonia Severity Index (PSI) ≥ 3 were independent risk factors for early events, and only PSI ≥ 3 for late events. Streptococcus pneumoniae was the microorganism associated with most cardiovascular complications. Developing CVE was an independent factor related to early (OR 2.37) and late mortality (OR 4.05).ConclusionsAge, smoking, chronic heart disease, initial severity, and S. pneumoniae infection are risk factors for early and late events, complications that have been related with an increase of the mortality risk during and after the pneumonia episode. Awareness of these factors can help us make active and early diagnoses of CVE in hospitalized CAP patients and design future interventional studies to reduce cardiovascular risk.     

Linfadenectomía de rescate en pacientes con cáncer de próstata tratados con prostatectomía radical o radioterapia y tomografía por emisión de positrones (PET) con colina positiva

Introduction and objectivesNodal prostate cancer recurrence is a challenging scenario. Current guidelines recommend the use of androgen deprivation therapy, tailored treatment or clinical trials. We studied the impact of Salvage lymph node dissection in selected patients.Material and methodsWe retrospectively reviewed records of 23 consecutive patients with prostate cancer and previous Radical prostatectomy or Radiotherapy who underwent SLND from December 2005 to November 2015.ResultsWe found that in patients that showed biochemical response the introduction of ADT was delayed 14.9 months compared to patients that did not responded (2.8 months) P=.00026. Furthermore although statistical significance was not reached (P=.072) PSA-DT could be a potential prognostic factor of radiological recurrence since patients with PSA-DT < 6 months developed radiological recurrence 7.6 months earlier compared to their counterparts.ConclusionsSalvage lymph node dissection is a potential treatment that could delay ADT in selected patients.     

The Validity and Sensitivity to Change of the Spanish Self-Administered Version of the Chronic Respiratory Questionnaire (CRQ-SAS)

IntroductionThe interviewer-administered chronic respiratory questionnaire (CRQ-IA) is widely used and has demonstrated excellent properties for measuring health-related quality of life (HRQL) in patients with chronic obstructive pulmonary disease (COPD). However, the self-administered version (CRQ-SAS) in Spanish has not been validated.The aim of this trial was to evaluate the validity and the sensitivity of the Spanish version of the CRQ-SAS in patients with COPD.Material and methodsWe randomized 40 patients with COPD (33 treated with pulmonary rehabilitation and 7 with liquid oxygen therapy) to one of the two methods of administration of CRQ (SAS vs IA) both before and 8 weeks after the treatment. In addition, patients completed the SF-36 questionnaire, pulmonary function tests, and 6-min walk test.ResultsThe CRQ-SAS demonstrated good longitudinal construct validity on all domains with a range of correlations, for the change scores, between 0.46 (P=.05) and 0.71 (P=.01). Regarding sensitivity to change, we observed a minimal clinically significant change in most domains (fatigue 0.71 [P=.02], emotional factor 0.62 [P=.04], and control of the disease 0.83 [P=.06]).ConclusionsThe Spanish version of CRQ-SAS is valid for evaluating HRQL in COPD patients. The correlations of the CRQ-SAS with other tools provide construct validity and show good sensitivity to change.     

Validation of Two Clinical Prognostic Models in Patients With Acute Symptomatic Pulmonary Embolism

ObjectiveThe aim of this study was to compare the predictive value of two clinical prognostic models, the Spanish score and the simplified Pulmonary Embolism Severity Index (sPESI), in an independent cohort of patients diagnosed of acute symptomatic pulmonary embolism (PE).MethodsWe performed a retrospective analysis of a cohort composed of 1447 patients with acute symptomatic PE. The Spanish score and the sPESI were calculated for each patient according to different clinical variables. We assessed the predictive accuracy of these scores for 30-day mortality, and a composite of non fatal recurrent venous thromboembolism and non fatal major bleeding, using C statistic, which was obtained by means of logistic regression and ROC curves.ResultsOverall, 138 patients died (9.5%) during the first month of follow-up. Both scores showed an excellent predictive value for 30-day all-cause mortality (C statistic, 0.72 and 0.74), but the performance was poor for the secondary endpoint (C statistic, 0.60 and 0.59). The sPESI classified fewer patients as low risk (32% versus 62%; P<.001). Low-risk patients based on the sPESI had a lower 30-day mortality than those based on the Spanish score (1.1% versus 4.2%), while the 30-day rate of non fatal recurrent VTE or major bleeding was similar (2.2% versus 2.3%).ConclusionsBoth scores provide excellent information to stratify the risk of mortality in patients treated of PE. The usefulness of these models for nonfatal adverse events is questionable. The sPESI identified low-risk patients with PE better than the Spanish score.     

Pneumonia as Comorbidity in Chronic Obstructive Pulmonary Disease (COPD). Differences Between Acute Exacerbation of COPD and Pneumonia in Patients With COPD

IntroductionPneumonia is considered an independent entity in chronic obstructive pulmonary disease (COPD), to be distinguished from an infectious exacerbation of COPD. The aim of this study was to analyze the clinical characteristics and progress of the exacerbation of COPD (ECOPD) compared to pneumonia in COPD (PCOPD) patients requiring hospitalization.Patients and methodsProspective, longitudinal, observational cohort study including 124 COPD patients requiring hospital admission for lower respiratory tract infection. Patients were categorized according to presence of ECOPD (n=104) or PCOPD (n=20), depending on presence of consolidation on X-ray. Demographic, clinical, laboratory, microbiological and progress variables were collected.ResultsPatients with ECOPD showed more severe respiratory disease according to the degree of obstruction (P<.01) and need for oxygen therapy (P<.05). PCOPD patients showed increased presence of fever (P<.05), higher blood pressure (P<.001), more laboratory abnormalities (P<.05; leukocytosis, elevated CRP, low serum albumin) and increased presence of crepitus (P<.01). Microbiological diagnosis was achieved in 30.8% of cases of ECOPD and 35% of PCOPD; sputum culture yielded the highest percentage of positive results, predominantly Pseudomonas aeruginosa. Regarding the progress of the episode, no differences were found in hospital stay, need for ICU or mechanical ventilation.ConclusionsOur data confirm clinical and analytical differences between ECOPD and PCOPD in patients who require hospital admission, while there were no differences in subsequent progress.     

Predictors of postoperative emergency department visits after laparoscopic bariatric surgery

BackgroundPostoperative emergency department (ED) visits are a quality metric for bariatric surgical programs. Predictive factors of ED visits that do not result in readmission are not clear.ObjectivesWe aimed to identify predictors of ED visits in patients without readmission after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).SettingThe Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database.MethodsThe MBSAQIP database was queried for patients who underwent LSG and LRYGB from 2015 through 2017. Patients were grouped by those who presented to the ED (ED group) and those who did not. ED visits analyzed included only those that did not result in readmission. Multivariable forward selection logistic regression was used to report adjusted odds ratios (AORs) with 95% CIs for ED visits.ResultsOf 276,073 patients, 257,985 (93.4%) were in the group who did not present to the ED, and 18,088 (6.6%) were in the ED group. Most underwent LSG (71.9%) versus LRYGB (28.1%). Multivariable forward logistic regression identified outpatient treatment for dehydration (AOR, 22.26; 95% CI, 21.30–23.27; P < .001) as the most predictive factor of an ED visit, followed by urinary tract infection (AOR, 7.25; 95% CI, 6.22–8.46; P < .001), wound disruption (AOR, 4.63; 95% CI, 3.09–6.96; P < .001), and surgical site infection (AOR, 3.80; 95% CI, 3.38–4.28; P < .001).ConclusionsPostoperative complications were the strongest predictors of ED visits after laparoscopic bariatric surgery. Quality improvement initiatives should target these variables to decrease postoperative ED visits.     

Changes in Clinical Presentation and Staging of Lung Cancer Over Two Decades

IntroductionImportant clinical and epidemiological changes have been observed in lung cancer (LC) in our healthcare area compared to the previous decade. In the last 10 years, specific LC care circuits have been implemented and the active search for cases has been stepped up. The aim of this study was to analyze the progress of these changes over the last 20 years.MethodsThis is a retrospective study comparing clinical and epidemiological changes between 2 historical cohorts of LC patients (1992–1994 [group 1, 164 patients] and 2004–2006 [group 2, 250 patients]) and a current group from the period 2011–2012 (group 3, 209 patients).ResultsTwo hundred and nine (209) LC patients were included in group 3 (2011–2012 period). After comparing groups 3 and 2, a non-significant rise in smoking was observed in women (59% vs 41%, P=.25), while the prevalence of adenocarcinoma was unchanged (45% vs 44%, P=.9). The main changes observed were the increase in cases with previous malignancies (23% vs 16%, P=.04), the rise in patients with no associated LC symptoms (33% vs 16%, P<.001), and an increased number of localized NSCLC (non-small cell LC) diagnoses (42% vs 24% in series 2, P<.001 and 14.2% in series 1, P<.001).ConclusionsThe number of LC patients diagnosed in localized stages has increased significantly. Furthermore, the number of patients with no symptoms associated with LC and with a history of previous malignancy was significantly increased.     

Pathologic Versus Native Hip Fractures: Comparing 30-day Mortality and Short-term Complication Profiles

BackgroundA large body of research on native hip fractures has resulted in several evidence-based guidelines aimed at improving postsurgical care for these patients. In contrast, there is a paucity of data on pathologic hip fractures, and whether native hip fracture protocols are generalizable to this population is unknown. The purpose of this study was to compare mortality rates and complication profiles between patients with pathologic and native hip fractures.MethodsUsing the American College of Surgeons-National Surgical Quality Improvement Program (NSQIP) database, we identified patients who underwent surgical treatment for pathologic and native hip fractures from 2007 to 2017 and 2601 matched pairs were identified using propensity scoring. Baseline covariates were controlled for, and rates of 30-day postoperative complications and mortality were compared using McNemar’s test.ResultsPathologic hip fracture patients experienced significantly higher rates of death (6.3% vs 4.3%, P < .001), serious adverse events (17.3% vs 13.5%, P < .001), minor complications (34.3% vs 29.1%, P < .001), extended postoperative lengths of stay (30.2% vs 25.9%, P < .001), readmissions (11.9% vs 8.4%, P < .001), thromboembolic complications (3.0% vs 1.6%, P < .001), and perioperative transfusions (31.5% vs 26.4%, P < .001) compared to native hip fracture patients.ConclusionPathologic hip fractures result in significantly higher complication rates than native hip fractures after surgical treatment, suggesting that guidelines for native hip fractures may not be generalizable for pathologic hip fractures. Orthopedic surgeons should closely monitor these patients for deep vein thrombosis, utilize blood sparing techniques, and employ a multidisciplinary approach to help manage and prevent a more heterogenous profile of postsurgical complications.     

Male Sexual Function in Patients Receiving Different Types of Renal Replacement Therapy

BackgroundPatients with end-stage renal disease (ESRD) experience erectile dysfunction (ED). Although it is a benign disorder, ED is related to physical and psychosocial health, and it has a significant impact on the quality of life (QOL). The objective of the present study was to investigate the effects of different renal replacement therapies on ED.MethodsA total of 100 ESRD patients and 50 healthy men were recruited to the present cross-sectional study. The study was consisted of 53 renal transplantation (RT; group I; mean age, 39.01 ± 7.68 years; mean duration of follow-up, 97.72 ± 10.35 months) and 47 hemodialysis (HD) patients (group II; mean age, 38.72 ± 9.12 years; mean duration of follow-up, 89.13 ± 8.65 months). The control group consisted of 50 healthy men (group III; mean age 39.77 ± 8.51 years). Demographic data and laboratory values were obtained. All groups were evaluated with the following scales: International Index of Erectile Function (IIEF)-5 and Short Form (SF)-36 questionnaires, and Beck Depression Inventory (BDI). The patients whose IIEF score were ≤21 were accepted as having ED.ResultsThe mean age of these groups were similar (P > .05). Total IIEF-5 scores of men in groups I, II, and III were 19.5 ± 4.5, 16.4 ± 5.9, and 22.5 ± 3.4, respectively. The mean total IIEF-5 score of control group was higher than those of groups I and II (P < .001). Posttransplant group mean total IIEF-5 score was also higher than the HD group (P < .05). Groups I and II significantly differed from control group in terms of presence of ED (IIEF score ≤21: Group I, n = 28 [52.8%]; group II, n = 29 [61.7%]; and group III, n = 12 [%24], respectively [P < .001]), whereas there was no difference between groups I and II. In the logistic regression analysis (variables included age, BDI, and renal replacement therapy [HD and transplantation]), ED was independently associated with age (odds ratio [OR], 1.1; 95% confidence interval [CI], 1.05–1.2), BDI (OR, 1.1; 95% CI, 1.01–1.13). Additionally, ED was not associated with renal replacement therapy (OR, 1.46; 95% CI, 0.60–3.57). Physiologic health domain of SF-36 was significantly better in healthy controls (P < .001). Patient groups were similar in terms of BDI score (P > .05). ED score was negatively correlated with BDI (r = ?0.368; P < .001), and positively correlated with SF-36 (r = 0.495; P < .001) in all patient groups.ConclusionPatients with ESRD had significantly lower sexual function and lower QOL scores than the healthy control men. Notably, the mode of renal replacement therapy had no impact on male sexual function.     

Prophylactic antibiotic therapy after inhalation injury

ObjectiveInhalation injury is suspected in patients with facial and neck burn-injuries and in patients who suffered burns in an enclosed space. Inhalation injury is associated with a disappointingly high morbidity and mortality in spite of advances in diagnostics and therapy.Prophylactic antibiotic therapy in patients with diagnosed inhalation injury is still a controversial subject.The epidemiologic characteristics of the burn patients with diagnosed inhalation injury in our clinic receiving prophylactic antibiotic therapy and mortality of these patients will be referred in this study.MethodsPatients >16 years of age admitted to the burn unit between January 2008 and December 2012 and fulfilling the burn center referral criteria according the German Burn Association were enrolled in the study.Results58 patients (male:female 47:11) were diagnosed with an inhalation injury by their admission. The average length of hospital stay was 27.5 days, whereas of the patients with no inhalation injury was 16 days (p = 0.04). 56.9% of the patients underwent tracheostomy. An escalation of the antibiotic therapy was done in 39.7% of the patients with inhalation injury and in 20.3% of the patients without one. The mortality of inhalation injury patients was 12.1%.ConclusionsThe development of pneumonia is not influenced in a statistical significant way by the use of prophylactic antibiotics. We do recommend the administration of prophylactic antibiotic therapy to patients with diagnosed inhalation trauma, as the mortality of these patients was lower in comparison to other studies.

Determination of a Low Risk Group for Having Metastatic Nodules Not Detected by Computed Tomography Scan in Lung Metastases Surgery

IntroductionIn recent years, there has been debate regarding the diagnostic accuracy of computed tomography (CT) in the identification of lung metastases and the need for lung palpation to determine the number of metastatic nodules. The aim of this study was to determine in which patients the CT scan was more effective in detecting all metastases.MethodsWe studied all patients who underwent curative thoracotomy for pulmonary metastasis between 1998 and 2012. All cases were reviewed by two expert pulmonary radiologists before surgery. Statistical analyses were performed using Systat version 13.ResultsThe study included 183 patients (63.6% male) with a mean age of 61.7 years who underwent 217 interventions. The CT scan was correct in 185 cases (85.3%). Discrepancies observed: 26 patients (11.9%) with more metastases resected than observed and 6 cases (2.8%) with fewer metastases. In patients with one or two metastases of colorectal origin or a single metastasis of any other origin, the probability of finding extra nodules was 9.5%. In the remaining patients, the probability was 27.8%, with statistically significant differences (P=.001). The mean age of the patients in whom no unobserved nodules were detected was 62.9 years compared to 56.5 years on average in patients who were free from any metastases (P=.001).ConclusionsPatients older than 60 years, with one or two metastases of colorectal origin or a single metastasis from any other origin were considered to be the group with low probability of having more metastases resected than observed.     

Epidemiology,risk factors,and outcomes of infections in patients undergoing liver transplantation for hilar cholangiocarcinoma

The epidemiology of infection after liver transplantation for hilar cholangiocarcinoma has not been systematically investigated. In this study of 124 patients, 255 infections occurred in 105 patients during the median follow‐up of 4.2 years. The median time to first infection was 15.1 weeks (IQR 1.6‐62.6). The most common sites were the abdomen, bloodstream, and musculoskeletal system. Risk factors for any post‐transplant infection were pre‐transplant VRE colonization (Hazard Ratio [HR] 1.9, P=.002), living donor transplantation (HR 6.6, P<.001), longer cold ischemia time (HR 1.05 per 10 minutes, P<.001), donor CMV seropositivity (HR 2.2, P<.001), hepatic artery thrombosis (HR 2.6, P=.005), biliary stricture (HR 3.8, P=.002), intra‐abdominal fluid collection (HR 4.2, P<.001), and re‐operations within 1 month after transplantation (HR 1.7, P=.020). Abdominal infections were independently associated with hemodialysis requirement within 1 month after transplantation (HR 5.6, P=.006), hepatic artery thrombosis (HR 3.3, P=.007), biliary stricture (HR 5.2, P<.001), and abdominal fluid collection (HR 3.7, P=.0002). Bloodstream infections were independently associated with allograft ischemia (HR 17.8, P<.001), biliary stricture (HR 6.5, P=.005), and recipient VRE colonization (HR 4, P<.001). Abdominal infections (HR 2.3, P=.02) and Clostridium difficile infections (HR 4.6, P=.01) were independently associated with increased mortality.
