Laparoscopic pancreatoduodenectoy.

BACKGROUND: Pancreatoduodenectomy or Whipple's operation, is the elective surgical procedure to treat different periampullary diseases. Through the years this surgery has been doing open, but in the lasts decades thanks to the improve technology and trained surgeons, today is feasible doing it laparoscopic with good results. OBJECTIVE: To present the initial experience and results in totally laparoscopic pancreatoduodenectomy in Hospital Regional ISSSTE Puebla, reporting the second number of cases in México. METHOD: Since July 2014-July 2018, 8 patients has been operated by totally laparoscopic pancreatoduodenectomy, 7 in Hospital Regional ISSSTE Puebla and 1 in a private Hospital. RESULTS: Evaluating all the patients, not one had mortality during operation, no morbidity or immediate reoperation, so the results are favourable. CONCLUSION: Laparoscopic pancreatoduodenectomy is a very complex procedure but feasible, and good results depends on various factors, like the appropriate patient selection.

ANTECEDENTES: La pancreatoduodenectomía o cirugía de Whipple es el procedimiento de elección en el tratamiento de las enfermedades periampulares.

RESULTADOS: En todos los pacientes intervenidos los resultados son favorables, sin mortalidad transoperatoria y sin presentar complicaciones graves ni reintervención. CONCLUSIÓN: La pancreatoduodenectomía laparoscópica es un procedimiento de alta complejidad que, teniendo una adecuada selección de pacientes y un manejo multidisciplinario, se puede llevar a cabo con excelentes resultados.

Pre-Exposure Prophylaxis Counseling in a Community Sexual Health Clinic for Men Who Have Sex with Men in Lisbon, Portugal.

INTRODUCTION: Pre-exposure prophylaxis is defined as the use of antiretroviral drugs to prevent HIV acquisition in uninfected individuals. Recognizing the increasing use of informal pre-exposure prophylaxis in Portugal, CheckpointLX, a community clinic targeted to men who have sex with men in Lisbon, Portugal, began offering counselling and follow-up services prior to formal introduction. This study aims to characterize pre-exposure prophylaxis users attending CheckpointLX before formal pre-exposure prophylaxis introduction in Portugal, and those who were referred to pre-exposure prophylaxis in the National Health Service following formal approval of pre-exposure prophylaxis. MATERIAL AND METHODS: Data was collected by peer counsellors between May 2015 and September 2018 and inserted in a database. Medical care followed the European AIDS Clinical Society recommendations for pre-exposure prophylaxis eligibility, initiation and follow-up. For formal pre-exposure prophylaxis, the General-Directorate for Health's Pre-exposure Prophylaxis guidelines checklist was used. RESULTS: Until the end of May 2018, CheckpointLX had a total of 90 appointments for wild pre-exposure prophylaxis, of which 64 (71%) were first time visits. As for the 380 service users referred to the National Health Service, most were Portuguese (n = 318, 84%), and the mean age was 31 (8.9) years old. Condomless sex in the last six months with partners of unknown HIV status was the most common eligibility criteria (n = 59, 83%). DISCUSSION: Pre-exposure prophylaxis delivery should be complemented with effective information on the importance of immunization and education on safer practices of drug administration, in the scope of broader preventive sexual health care. CONCLUSION: Much remains to be done in Portugal to ensure that pre-exposure prophylaxis is available to those who need it the most. Offering pre-exposure prophylaxis at community clinics could be a first step.

Introdução: A profilaxia pré-exposição pode ser definida como o uso de medicamentos anti-retrovirais para prevenir a aquisição do VIH em indivíduos não infectados. Reconhecendo o uso crescente da profilaxia pré-exposição informal em Portugal, o CheckpointLX, uma clínica comunitária destinada a homens que têm sexo com homens em Lisboa, Portugal, começou a oferecer aconselhamento e serviços de acompanhamento antes da introdução formal. Este estudo pretende caracterizar os utilizadores da profilaxia pré-exposição que frequentam o CheckpointLX antes da introdução formal da profilaxia pré-exposição em Portugal, e aqueles que foram encaminhados para a profilaxia pré-exposição no Serviço Nacional de Saúde após a aprovação formal da profilaxia pré-exposição. Material e Métodos: Os dados foram colhidos por pares entre maio de 2015 e setembro de 2018 e inseridos numa base de dados. Os cuidados médicos seguiram as recomendações da European AIDS Clinical Society para elegibilidade, iniciação e acompanhamento da profilaxia pré-exposição. Para a profilaxia pré-exposição formal, foi utilizada a lista de verificação da Norma de Profilaxia Pré-exposição da Direção-Geral da Saúde. Resultados: Até ao final de maio de 2018, o CheckpointLX fez um total de 90 consultas para o wild pre-exposure prophylaxis, das quais 64 (71%) foram primeiras consultas. Quanto aos 380 utilizadores referenciados ao Serviço Nacional de Saúde, a maioria era de nacionalidade portuguesa (n = 318, 84%) e a idade média era de 31 (8,9) anos. Sexo sem preservativo nos últimos seis meses com parceiros com estatuto VIH desconhecido foi o critério de elegibilidade mais reportado (n = 59, 83%). Discussão: A dispensa da profilaxia pré-exposição deve ser complementada com informações eficazes sobre a importância da imunização e da educação em práticas mais seguras de administração de medicamentos, no âmbito de cuidados de saúde sexual preventivos mais amplos. Conclusão: Ainda há muito a ser feito em Portugal para garantir que a profilaxia pré-exposição esteja disponível para aqueles que mais dela precisam. Oferecer profilaxia pré-exposição em clínicas comunitárias pode ser um primeiro passo.

Are Patients Undergoing an Anterior Cervical Discectomy and Fusion Treated Differently at a Physician-owned Hospital?

STUDY DESIGN: Retrospective case-control study. BACKGROUND: Physician-owned specialty hospitals focus on taking care of patients with a select group of conditions. In some instances, they may also create a potential conflict of interest for the surgeon. The effect this has on the surgical algorithm for patients with degenerative cervical spine conditions has not been determined. METHODS: A retrospective review of all patients who underwent a 1- or 2-level anterior cervical discectomy and fusion between October 2009 and December 2014 at either a physician-owned specialty hospital or an independently owned community hospital were identified. Demographic information, the time course for treatment and the nonoperative treatment regimen were evaluated. RESULTS: In total, 115 patients undergoing surgery at a physician-owned specialty hospital and 149 patients undergoing surgery at an independent community hospital were identified. Demographic data between the groups including the presence of 12 medical comorbidities and insurance status was similar between the groups. The only difference that was identified was that patients at the surgeon-owned hospital were marginally younger than patients who had surgery at the independent hospital (49.7 vs. 50.0, P=0.048). No difference in the median number of months from the onset of symptoms to surgery (6.51 vs. 7.53 mo, respectively; P=0.55), from the onset of symptoms to the preoperative visit (6.02 vs. 6.02, P=0.64), or from the initial surgical consultation to surgery (0.99 vs. 1.02, P=0.31) was identified. No difference in the number of patients who underwent formal physical therapy (72.2% vs. 67.1%, P=0.42) or who had a cervical steroid injection (55.6% vs. 50.3%, P=0.25%) was identified between patients who had surgery at a physician-owned or independent hospital; however, patients who underwent surgery at the physician-owned hospital were more likely to have taken oral anti-inflammatories (93.0% vs. 83.9%, P=0.04). CONCLUSIONS: When comparing hospitals with similar resources, surgeons do not preferentially select younger, healthier patients with higher paying insurance to be treated at the physician-owned hospital. Furthermore, both the time from the onset of symptoms to surgery and the nonoperative treatment regimen were similar between patients treated at the 2 facilities.

Cryptococcosis in an Infectious Diseases Hospital of Buenos Aires, Argentina. Revision of 2041 cases: Diagnosis, clinical features and therapeutics.

BACKGROUND: Cryptococcosis is still a life-threatening mycosis that continues to be of serious concern in Latin American countries, especially among HIV+positive population. However, there is not any reliable information about the prevalence of this disease in this region. AIMS: The aim of this study is to report data of 2041 patients with cryptococcosis that were attended at the Infectious Diseases Hospital F. J. Muñiz over a 30 year-period. METHODS: Information about demographic and clinical data, survival time and the applied treatment, was taken from the Mycology Unit database. Mycological exams from different clinical samples were performed. Cryptococcal capsular antigen in serum and cerebrospinal fluid was detected through the latex agglutination technique. Cryptococcus isolates were phenotypically identified and the genotype was determined in some of them. Susceptibility tests were carried out following M27-A3 document. RESULTS: Seventy five percent of HIV+positive patients and 50% of the HIV-negative population were males. Mean ages were 34.1 in HIV+positive patients and 44.8 in the HIV-negative. Cryptococcosis was associated with AIDS in 98% of the cases. Meningeal compromise was seen in 90% of the patients. Although cerebrospinal fluid rendered more positive results, blood culture was the first diagnostic finding in some cases. Cryptococcal antigen showed positive results in 96.2% of the sera samples and in the 93.1% of the cerebrospinal fluid samples. Most of the isolates were Cryptococcus neoformans and belonged to genotype VNI. Minimal inhibitory concentration values were mostly below the epidemiological cutoff values. CONCLUSIONS: We observed that thanks to a high level of clinical suspicion, early diagnosis, combined therapy and intracranial pressure control by daily lumbar punctures, the global mortality rate has markedly decreased through the years in the analyzed period.

Disseminated histoplasmosis in AIDS patients: an urban disease. Experience in a metropolis in the middle east of Brasil.

Histoplasmosis is a fungal disease commonly observed as an opportunistic disease in AIDS patients. It is a neglected disease in many countries, particularly Latin America, including Brazil. It is related with environmental factors, even in urban areas, where the incidence has increased. Implementing a descriptive ecological study, we performed a retrospective chart review for data collected between January 2003 and July 2014 for AIDS patients with histoplasmosis who lived in Goiania. The selected cases were georeferenced to analyse the incidence of histoplasmosis in AIDS patients in the metropolitan area of Goiania. In all, 166 patients (130 men) met the criteria for AIDS and histoplasmosis coinfection. Almost half of the patients (41%) had simultaneous histoplasmosis and AIDS diagnoses. The general mortality was 53% (88 patients). The main symptoms involved the respiratory, gastrointestinal, and cutaneous systems. The distribution of cases included almost all regions of the urban areas, with some predominance in the eastern and western regions close to areas of environmental degradation, contaminated water sources and unplanned urbanisation. In conclusion, coinfection with HIV and disseminated histoplasmosis is common and associated with high mortality rates in our referral hospital for infectious diseases. Despite being considered as having a predominantly rural epidemiology, many patients reported living in urban areas such as Goiânia and Aparecida de Goiânia. Our findings suggest the need for environmental studies to evaluate environmental contamination and possible local risk factors for H. capsulatum infection in addition to serological surveys to determine the prevalence of this infection in the studied cities.

Health-related quality of life in adults with irritable bowel syndrome in a Mexican specialist hospital. A cross-sectional study.

BACKGROUND: Evidence shows the negative impact of irritable bowel syndrome on the quality of life of patients who suffer from the condition as compared to the general population. OBJECTIVE: The objective of this study was to determine the health-related quality of life in adults with irritable bowel syndrome who are receiving treatment at a specialist hospital. MATERIAL AND METHODS: The study had a cross-sectional prospective design. The study included consecutive patients diagnosed with irritable bowel syndrome under the Rome III criteria and attending outpatient appointments. The SF-36 questionnaire was applied in its standard Spanish version and the results were compared with population reference scores in Mexico. Statistical analysis was performed with the Student's t test, analysis of variance and the Chi-squared test, considering a significance of 0.05%. RESULTS: One hundred and fifty-four patients were included in the study, 137 (89%) women and 17 (11%) men, with an average age of 52.8 (SD 12.6). The constipation, diarrhea and mixed subtypes comprised 85 (55.2%), 27 (17.5%) and 42 (27.3%) patients, respectively. The quality of life of patients with irritable bowel syndrome vs the population reference scores in Mexico were 50 vs 79 for the physical health sub-scale and 59.1 vs 76.7 for the mental health sub-scale, respectively (p = 0.000). No significant difference was found in quality of life among the irritable bowel syndrome subtypes (p > 0.05). CONCLUSIONS: Health-related quality of life is lower in patients with irritable bowel syndrome in a population in the North East of Mexico compared to the data taken from a population reference study undertaken in the same country, enabling an inference in the female population and a cautious one from the results found in the small male sample studied. There was no significant difference found in the quality of life according to the clinical subtype of irritable bowel syndrome.

[Incidence of hip and knee prosthetic infections in a specialized center of Mexico City]. / Incidencia de infecciones protésicas primarias de cadera y rodilla en un centro de la Ciudad de México.

BACKGROUND: Hip and knee prosthetic replacements have proven to be the most appropriate treatment in the joints that do not benefit from medical or arthroscopic interventions; however, infections are the most feared complication. It is recommended that the incidence of infection should not exceed 2%. MATERIAL AND METHODS: This was an observational, prospective, longitudinal and observational study conducted in patients fitted with a prosthetic joint from August 2011 to July 2012. Patients were followed up pre and post-surgery for one year to identify a prosthetic infection, diagnosed using international parameters. We calculated the incidence of prosthetic infection, as well as the incidence density. RESULTS: A total of 339 patients (179 hip and 160 knee) were included. Variations in the time of pre-operative antibiotics' administration were observed. Six prosthetic infections were identified with an incidence rate of 1.79/339 arthroplasties, 2.2/179 hip procedures, and 1.25/160 knee arthroplasties. An incidence density of 0.02/year for hip arthroplasties and 0.11/year for knee procedures was identified. There were 4 infections of hip and 2 of knee. Five infections were acute and one chronic. The isolated microorganisms were E. faecalis, S. epidermidis (2), S. mitis, S. aureus and P. stomatis. CONCLUSIONS: The incidence of prosthetic joint infection in the first year of follow-up at our centre is within the recommended parameters. Surgical techniques and organizational practices influence the results.

Comparing the Treatment Algorithm and Complications for Patients Undergoing an Anterior Cervical Discectomy and Fusion at a Physician-Owned Specialty Hospital and a University-Owned Tertiary Care Hospital.

The purpose of this case-control study is to compare the treatment algorithm and complication rate for patients who undergo an anterior cervical discectomy and fusion at a physician-owned specialty hospital to those who undergo surgery at a university-owned tertiary care hospital. Two controls were identified for 77 patients, and no differences in demographic data were identified. The median time between the onset of symptoms and surgery was shorter for patients who had surgery at the tertiary care center than for patients who had surgery at the specialty hospital (26.7 weeks vs 32.7 weeks, P = .0004). Furthermore, a higher percentage of patients who had surgery at the specialty hospital attempted nonoperative treatments than patients who underwent surgery at the tertiary care hospital.

[Initial experience in the laparoscopic treatment of benign and malignant gynaecological diseases in the Hospital Regional de Alta Especialidad in Oaxaca]. / Experiencia inicial en el tratamiento de enfermedad ginecológica benigna y maligna por laparoscopia en el Hospital Regional de Alta Especialidad de Oaxaca.

BACKGROUND: The history of laparoscopic surgery in gynaecological diseases progressed with the advances of Semm, as well as with the development of tools, equipment, and energy that led to its development in all surgical areas, including oncology. OBJECTIVE: To present the initial experience in the laparoscopic treatment of benign and malignant gynaecological disease in the Hospital Regional de Alta Especialidad in Oaxaca. MATERIAL AND METHODS: An analysis was performed on a total of 44 cases, distributed into: type III radical hysterectomy for invasive cervical cancer, hysterectomy type I cervical cancer in situ, extrafascial hysterectomy for benign disease, routine endometrium, ovary and routine salpingo-oophorectomy. The variables included age, BMI, surgical time, bleeding, intraoperative and postoperative complications, conversion, hospital stay, and pathology report. RESULTS: Hysterectomy type III; age 40.2 years, BMI 25.8kg/m2, 238ml bleeding, operative time 228min, 2.6-day hospital stay, intraoperative or postoperative complications, tumour size 1.1cm, 14 lymph nodes dissected, vaginal and negative parametrical edge. Type I hysterectomy cervical cancer in situ: 51 years, BMI 23.8kg/m2, 80ml bleeding, operative time 127minutes, uterus of 9cm, length of stay of 2 days, a conversion by external iliac artery injury, with bleeding of 1500ml. Routine endometrium: 50.3 years, BMI 30.3kg/m2, 83ml bleeding, operative time 180minutes, uterus 12.6cm, length of stay 2.3 days, no complications. CONCLUSION: The management of benign and malignant pelvic diseases using laparoscopy is feasible and safe, with shorter hospital stays and a prompt recovery to daily activities.

Spending on Bariatric Surgery in the Unified Health System from 2010 to 2014: a Study Based on the Specialist Hospitals Authorized by the Ministry of Health.

BACKGROUND: The aim of this study is to analyze the production of 76 specialist hospitals for the morbidly obese in Brazil's public healthcare system (SUS) from 2010 to 2014 in terms of quantity and costs of bariatric surgery and its complications. METHODS: Secondary data from the SUS Hospital Information System and the National Healthcare Establishments Registry were used. Current spending on bariatric surgery and its medical and postoperative complications were analyzed. RESULTS: There was a 60 % rise in the number of surgeries between 2010 and 2014. This increase was not homogeneous among the hospitals studied, since only 19 performed the minimum number of surgeries required. Women accounted for 85 % of the surgeries carried out, and 32 % were aged between 35 and 44 years. The Roux-en-Y technique was the most widely used (93.7 % of the total), followed by sleeve gastrectomy. The ratio between the occurrence of medical complications and total number of surgeries performed in each hospital varied significantly (between 0 and 5.97 %) but was lower for postoperative complications, ranging from 0 to 1.7 %. There was a nominal increase of 44 % in average expenditure on postoperative complications between 2013 and 2014, while the average cost of medical complications decreased by 8.7 % in the same period. CONCLUSIONS: Despite the rise in the number of bariatric surgeries in Brazil, there is still a high demand for surgeries that is not being met, while most specialist hospitals fail to perform the minimum number of surgeries stipulated by the Ministry of Health.

RESUMO Objetivo: analisar a prevalência das uveítes em pacientes atendidos em um serviço oftalmológico terciário em Teresina, Piauí. Métodos: estudo retrospectivo baseado em prontuários de pacientes atendidos nesse serviço. Foram descritos: gênero, faixa etária, procedência, doença de base, diagnóstico anatômico, aspecto clínico e tempo de evolução. Resultados: foram incluídos 403 prontuários constatando-se que a cada 1000 pacientes atendidos neste serviço, 3,2 tinham uveíte.A idade média dos pacientes foi de 42 anos, tanto o gênero feminino (50,6%) quanto o gênero masculino (49,4%) foram acometidos similarmente, com 61,5% dos pacientes provenientes da capital. A doença de base mais frequente foi a toxoplasmose, seguida das uveítes idiopáticas apenas com manifestações oculares. Quanto à classificação anatômica, 49,6% foram posteriores e 3,5% foram intermediárias. Em relação ao aspecto clínico, 64% foram granulomatosas, 24,8% não-granulomatosas e 11,2% não foram classificáveis. Segundo a evolução clínica, 41,4% foram agudas, seguidas de 30,8% crônicas, 14,4% recorrentes e em 13,4% os pacientes não foi feito o acompanhamento. Conclusão: pudemos constatar que para cada 1000 pacientes atendidos neste serviço 3,2 tinham uveíte, apresentando-se a toxoplasmose como importante fonte de uveíte neste serviço.

ABSTRACT Objective: To analyze the prevalence of uveitis in patients treated at a tertiary ophthalmic service in Teresina, Piauí State, Brazil. Methods: This was a retrospective study based on medical records of patients treated at this service. Sex, age, origin, underlying diseases, anatomical diagnosis, clinical aspects and progression time were described. Results: 403 records were included, noting that 3.2 out of every 1,000 patients treated at the service had uveitis.The average age of patients was 42 years old, with both sexes (50.6% females and 49.4% males) affected similarly, and with 61.5% coming from the state capital, Teresina. The most common underlying disease was toxoplasmosis, followed by idiopathic uveitis with ocular manifestations only. As to the anatomical classification, 49.6% of them were posterior and only 3.5% were intermediate. Regarding the clinical aspects, 64% were granulomatous, 24.8% non-granulomatous, and 11.2% were not classifiable. According to the clinical progression, 41.4% were acute, followed by 30.8% chronic, 14.4% recurrent cases, and 13.4% of patients did not return for medical care. Conclusion: we found that for every 1,000 patients treated at the service, 3.2 had uveitis, with toxoplasmosis itself found to be an important source of uveitis.

Initial Report on the Results of the Kidney Transplant Program at the Bajio Regional High Specialty Hospital.

BACKGROUND: We present the first results of our program, which is characterized by its acceptance of any candidate with chronic renal failure. Therefore, we serve all patients, regardless of their social security and socioeconomic status. METHODS: We conducted a retrospective, descriptive, cross-sectional study describing the characteristics of patients who received kidney transplants in the period from 2008 to 2015. Descriptive statistics were used to evaluate our findings. RESULTS: A total of 708 transplants were performed, with 377 (53%) involving a living donor and 331 (47%) involving deceased donors. The patients' mean age was 26 years (±12.7 SD), with a range of 5 to 69 years. Of these patients, 488 were male (68.9%), and 423 (59.7%) had no social security. The replacement therapy prior to transplantation was peritoneal dialysis in 40% of cases, hemodialysis in 57% of cases, and 3% of patients had no prior therapy. The blood group distribution was 436 (61%) type O; 177 (25%) type A; 78 (11%) type B; and 8 (1%) type AB. The average hospital stay for a living donor transplant was 9 days and 13 days in the case of a deceased donor. CONCLUSIONS: This study describes the basic clinical and epidemiological characteristics of our transplant population. These results can be used as a basis for future descriptive and prospective studies at our institution or in other inter-agency and national projects. We also highlight the rapid development of the kidney transplant program at the Bajio Regional High Specialty Hospital.

Aortic Center: specialized care improves outcomes and decreases mortality / Centro de Tratamento da Aorta: a especialização reduz complicações e mortalidade

Objective: To compare in-hospital outcomes in aortic surgery in our cardiac surgery unit, before and after foundation of our Center for Aortic Surgery (CTA). Methods: Prospective cohort with non-concurrent control. Foundation of CTA required specialized training of surgical, anesthetic and intensive care unit teams, routine neurological monitoring, endovascular and hybrid facilities, training of the support personnel, improvement of the registry and adoption of specific protocols. We included 332 patients operated on between: January/2003 to December/2007 (before-CTA, n=157, 47.3%); and January/2008 to December/2010 (CTA, n=175, 52.7%). Baseline clinical and demographic data, operative variables, complications and in-hospital mortality were compared between both groups. Results: Mean age was 58±14 years, with 65% male. Group CTA was older, had higher rate of diabetes, lower rates of COPD and HF, more non-urgent surgeries, endovascular procedures, and aneurysms. In the univariate analysis, CTA had lower mortality (9.7 vs. 23.0%, P=0.008), which occurred consistently across different diseases and procedures. Other outcomes which were reduced in CTA included lower rates of reinterventions (5.7 vs 11%, P=0.046), major complications (20.6 vs. 33.1%, P=0.007), stroke (4.6 vs. 10.9%, P=0.045) and sepsis (1.7 vs. 9.6%, P=0.001), as compared to before-CTA. Multivariable analysis adjusted for potential counfounders revealed that CTA was independently associated with mortality reduction (OR=0.23, IC 95% 0.08 – 0.67, P=0.007). CTA independent mortality reduction was consistent in the multivariable analysis stratified by disease (aneurysm, OR=0.18, CI 95% 0.03 – 0.98, P=0.048; dissection, OR=0.31, CI 95% 0.09 – 0.99, P=0.049) and by procedure (hybrid, OR=0.07, CI 95% 0.007 – 0.72, P=0.026; Bentall, OR=0.18, CI 95% 0.038 – 0.904, P=0.037). Additional multivariable predictors of in-hospital mortality included creatinine ...

Objetivo: Comparar desfechos intrahospitalares em pacientes submetidos a cirurgia da aorta torácica e toracoabdominal, antes e após a constituição do Centro Especializado de Tratamento da Aorta (CTA). Métodos: Coorte prospectiva com controle não contemporâneo. A criação do CTA envolveu treinamento cirúrgico especializado, sala híbrida, monitorização neurológica, capacitação de pessoal de apoio, aperfeiçoamento dos registros e uso de protocolos específicos. Foram incluídos 332 pacientes operados em 2 períodos: janeiro/2003 a dezembro/2007 (pré-CTA, n=157, 47,3%); e janeiro/2008 a dezembro/2010 (CTA, n=175, 52,7%). As características demográficas, clínicas, dados cirúrgicos, complicações e mortalidade hospitalar foram comparados nos 2 grupos. Resultados: A idade média foi 58±14 anos, com 65% sexo masculino. O grupo CTA teve idade, prevalência de diabete (DM) e glicemia maiores; menor prevalência de doença pulmonar obstrutiva crônica e insuficiência cardíaca; maior proporção de aneurismas e cirurgias eletivas; e mais procedimentos endovasculares que o pré-CTA. Na análise univariada, o grupo CTA mostrou redução de mortalidade (9,7% x 23,0%, P=0,008), que foi consistente nos diferentes subgrupos estratificados por patologia e por procedimento. O grupo CTA teve também redução de reoperações (5,7% x 11%, P=0,046), complicações maiores (20,6% x 33,1%, P=0,007), acidente vascular cerebral (4,6% x 10,9%, P=0,045) e sepse (1,7% x 9,6%, P=0,001), comparado ao pré-CTA. Na análise multivariada, o CTA se associou de forma independente a redução de mortalidade hospitalar (OR=0,23, IC 95% 0,08 - 0,67, P=0,007). A redução de mortalidade do CTA também ocorreu na análise estratificada por patologia (cirurgias de aneurisma, OR=0,18, IC 95% 0,03 - 0,98, P=0,048; cirurgias de dissecção, OR=0,31, IC 95% 0,09 - 0,99, P=0,049) e por procedimento (híbridos, OR=0,07, IC 95% 0,007 - 0,72, P=0,026; Bentall, OR=0,18, IC 95% 0,038 – 0,904, P=0,037).

Transfer rates from nonprocedure hospitals after initial admission and outcomes among elderly patients with acute myocardial infarction.

IMPORTANCE: It is unknown whether hospital transfer rates for patients with acute myocardial infarction admitted to nonprocedure hospitals (facilities that do not provide catheterization) vary and whether these rates further influence revascularization rates, length of stay, and mortality. OBJECTIVES: To examine hospital differences in transfer rates for elderly patients with acute myocardial infarction across nonprocedure hospitals and to determine whether these rates are associated with revascularization rates, length of stay, and mortality. DESIGN, SETTING, AND PARTICIPANTS: We used Medicare claims data from January 1, 2006, to December 31, 2008, to assess transfer rates in nonprocedure hospitals, stratified according to transfer rates as low (≤ 20%), mid-low (>20%-30%), mid-high (>30%-40%), or high (>40%). Data were analyzed for 55,962 Medicare fee-for-service patients admitted to 901 nonprocedure US hospitals with more than 25 admissions per year for acute myocardial infarction. MAIN OUTCOMES AND MEASURES: We compared rates of catheterization, percutaneous coronary intervention, and coronary artery bypass graft surgery during hospitalization and within 60 days, as well as hospital total length of stay, across groups. We measured risk-standardized mortality rates at 30 days and 1 year. RESULTS The median transfer rate was 29.4% (interquartile range [25th-75th percentile], 21.8%-37.8%). Higher transfer rates were associated with higher rates of catheterization (P < .001), percutaneous coronary intervention (P < .001), and coronary artery bypass graft surgery (P < .001). Median length of stay was not meaningfully different across the groups. There was no meaningful evidence of associations between transfer rates and risk-standardized mortality at 30 days (mean [SD], 22.3% [2.6%], 22.1% [2.3%], 22.3% [2.4%], and 21.7% [2.1%], respectively; P = .054) or 1 year (43.9% [2.3%], 43.6% [2.2%], 43.5% [2.4%], and 42.8% [2.2%], respectively; P < .001) for low, mid-low, mid-high, and high transfer groups. CONCLUSIONS AND RELEVANCE: Nonprocedure hospitals vary substantially in their use of the transfer process for elderly patients admitted with acute myocardial infarction. High-transfer hospitals had greater use of invasive cardiac procedures after admission compared with low-transfer hospitals. However, higher transfer rates were not associated with a significantly lower risk-standardized mortality rate at 30 days. Moreover, at 1 year there was only a 1.1% difference (42.8% vs 43.9%) between hospitals with higher and lower transfer rates. These findings suggest that, as a single intervention, promoting the transfer of patients admitted with acute myocardial infarction may not improve hospital outcomes.

METHODS: Prospective cohort with non-concurrent control. Foundation of CTA required specialized training of surgical, anesthetic and intensive care unit teams, routine neurological monitoring, endovascular and hybrid facilities, training of the support personnel, improvement of the registry and adoption of specific protocols. We included 332 patients operated on between: January/2003 to December/2007 (before-CTA, n=157, 47.3%); and January/2008 to December/2010 (CTA, n=175, 52.7%). Baseline clinical and demographic data, operative variables, complications and in-hospital mortality were compared between both groups. RESULTS: Mean age was 58±14 years, with 65% male. Group CTA was older, had higher rate of diabetes, lower rates of COPD and HF, more non-urgent surgeries, endovascular procedures, and aneurysms. In the univariate analysis, CTA had lower mortality (9.7 vs. 23.0%, P=0.008), which occurred consistently across different diseases and procedures. Other outcomes which were reduced in CTA included lower rates of reinterventions (5.7 vs 11%, P=0.046), major complications (20.6 vs. 33.1%, P=0.007), stroke (4.6 vs. 10.9%, P=0.045) and sepsis (1.7 vs. 9.6%, P=0.001), as compared to before-CTA. Multivariable analysis adjusted for potential confounders revealed that CTA was independently associated with mortality reduction (OR=0.23, IC 95% 0.08 - 0.67, P=0.007). CTA independent mortality reduction was consistent in the multivariable analysis stratified by disease (aneurysm, OR=0.18, CI 95% 0.03 - 0.98, P=0.048; dissection, OR=0.31, CI 95% 0.09 - 0.99, P=0.049) and by procedure (hybrid, OR=0.07, CI 95% 0.007 - 0.72, P=0.026; Bentall, OR=0.18, CI 95% 0.038 - 0.904, P=0.037). Additional multivariable predictors of in-hospital mortality included creatinine (OR=1.7 [1.1-2.6], P=0.008), urgent surgery (OR=5.0 [1.5-16.7], P=0.008) and thoracoabdominal aneurysm (OR=24.6 [3.1-194.1], P=0.002). CONCLUSION: Thoracic aorta surgery in specialized center was associated with lower incidence of complications and all-cause mortality as compared to usual care.

[In-hospital mortality due to stroke]. / Mortalidad intrahospitalaria por accidente cerebrovascular.

Overall mortality due to stroke has decreased in the last three decades probable due to a better control of vascular risk factors. In-hospital mortality of stroke patients has been estimated to be between 6 and 14% in most of the series reported. However, data from recent clinical trials suggest that these figures may be substantially lower. Data from FLENI Stroke Data Bank and institutional mortality records between 2000 and 2010 were reviewed. Ischemic stroke subtypes were classified according to TOAST criteria and hemorrhagic stroke subtypes were classified as intraparenchymal hematoma, aneurismatic subarachnoid hemorrhage, arterio-venous malformation, and other intraparenchymal hematomas. A total of 1514 patients were studied. Of these, 1079 (71%) were ischemic strokes,39% large vessels, 27% cardioembolic, 9% lacunar, 14% unknown etiology, and 11% others etiologies. There were 435 (29%) hemorrhagic strokes, 27% intraparenchymal hematomas, 30% aneurismatic subarachnoid hemorrhage, 25% arterio-venous malformation, and 18% other intraparenchymal hematomas. Moreover, 38 in-hospital deaths were recorded (17 ischemic strokes and 21 hemorrhagic strokes), accounting for 2.5% overall mortality (1.7% in ischemic strokes and 4.8% in hemorrhagic strokes). No deaths occurred associated with the use of intravenous fibrinolytics occurred. In our Centre in-hospital mortality in patients with stroke was low. Management of these patients in a Centre dedicated to neurological diseases along with a multidisciplinary approach from medical and non-medical staff trained in the care of cerebrovascular diseases could, at least in part, account for these results.

Mortalidad intrahospitalaria por accidente cerebrovascular / In-hospital mortality due to stroke

La mortalidad global por accidente cerebrovascular (ACV) ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71%) con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11%) y 435 (29%) con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%). Se registraron 38 muertes intrahospitalarias (17 ACV isquémicos y 21 ACV hemorrágicos), representando una mortalidad global del 2.5% (1.7% en ACV isquémicos y 4.8% en ACV hemorrágicos). No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.
