Patients With Endometriosis of the Rectosigmoid Have a Higher Percentage of Natural Killer Cells in Peripheral Blood

Study Objective: To estimate the concentration of natural killer (NK) cells in the peripheral blood in patients with and without endometriosis. Design: Case-control study (Canadian Task Force classification II-2). Setting: Tertiary referral hospital. Patients: One hundred fifty-five patients who had undergone videolaparoscopy were divided into 2 groups: those with endometriosis (n = 100) and those without endometriosis (n = 55). Interventions: The percentage of NK cells relative to peripheral lymphocytes was quantified at flow cytometry in 155 patients who had undergone laparoscopy. In addition to verifying the presence of endometriosis, stage of disease and the sites affected were also evaluated. Measurements and Main Results: The mean (SD) percentage of NK cells was higher (15.3% [9.8%]) in patients with endometriosis than in the group without the disease (10.6% [5.8%]) (p < .001). The percentage of NK cells was highest (19.8 [10.3%]) in patients with advanced stages of endometriosis and in those in whom the rectosigmoid colon was affected. In a statistical model of probability, the association of this marker (NK cells >= 11%) with the presence of symptoms such as pain and intestinal bleeding during menstruation and the absence of previous pregnancy yielded a 78% likelihood of the rectosigmoid colon being affected. Conclusion: Compared with patients without endometriosis, those with endometriosis demonstrate a higher concentration of peripheral NK cells. The percentage of NK cells is greater, primarily in patients with advanced stages of endometriosis involving the rectosigmoid colon. Therefore, it may serve as a diagnostic marker for this type of severe endometriosis, in particular if considered in conjunction with the symptoms.

Effects of neuromuscular electrostimulation in patients with heart failure admitted to ward

Background: Neuromuscular electrostimulation has become a promising issue in cardiovascular rehabilitation. However there are few articles published in the literature regarding neuromuscular electrostimulation in patients with heart failure during hospital stay. Methods: This is a randomized controlled pilot trial that aimed to investigate the effect of neuromuscular electrostimulation in the walked distance by the six-minute walking test in 30 patients admitted to ward for heart failure treatment in a tertiary cardiology hospital. Patients in the intervention group performed a conventional rehabilitation and neuromuscular electrostimulation. Patients underwent 60 minutes of electrostimulation (wave frequency was 20 Hz, pulse duration of 20 us) two times a day for consecutive days until hospital discharge. Results: The walked distance in the six-minute walking test improved 75% in the electrostimulation group (from 379.7 +/- 43.5 to 372.9 +/- 46.9 meters to controls and from 372.9 +/- 62.4 to 500 +/- 68 meters to electrostimulation, p<0.001). On the other hand, the walked distance in the control group did not change. Conclusion: The neuromuscular electrostimulation group showed greater improvement in the walked distance in the six-minute walking test in patients admitted to ward for compensation of heart failure.

Percepção de pacientes sobre a privacidade no hospital

Estudo qualitativo empregando a análise de conteúdo, objetivando descrever a percepção de privacidade do paciente hospitalizado. Participaram 34 pacientes internados há, pelo mínimo, 3 dias. A análise das informações, fundamentada no referencial teórico da privacidade, evidenciou 3 categorias temáticas: dignidade e respeito, autonomia, espaço pessoal e territorial. Os sujeitos apontaram fatores comportamentais que contribuem ou não para a proteção e manutenção da privacidade no hospital, destacando o respeito como aspecto mais importante, seguido pelo controle pessoal sobre situações que transgridem sua privacidade. Para eles privacidade está interligada com dignidade e respeito, depende da demarcação do espaço pessoal/territorial e da garantia de autonomia, estando esses conceitos e atitudes inter-relacionados e sendo imprescindíveis para o resguardo da privacidade no ambiente hospitalar.

Association between systemic corticosteroids and outcomes of intensive care unit-acquired pneumonia

Objective: The use of corticosteroids is frequent in critically-ill patients. However, little information is available on their effects in patients with intensive care unit acquired pneumonia. We assessed patients' characteristics, microbial etiology, inflammatory response, and outcomes of previous corticosteroid use in patients with intensive care unit acquired pneumonia. Design: Prospective observational study. Setting: Intensive care units of a university teaching hospital. Patients: Three hundred sixteen patients with intensive care unit acquired pneumonia. Patients were divided according to previous systemic steroid use at onset of pneumonia. Interventions: None. Measurements and Main Results: Survival at 28 days was analyzed using Cox regression, with adjustment for the propensity for receiving steroid therapy. One hundred twenty-five (40%) patients were receiving steroids at onset of pneumonia. Despite similar baseline clinical severity, steroid treatment was associated with decreased 28-day survival (adjusted hazard ratio for propensity score and mortality predictors 2.503; 95% confidence interval 1.176-5.330; p = .017) and decreased systemic inflammatory response. In post hoc analyses, steroid treatment had an impact on survival in patients with nonventilator intensive care unit acquired pneumonia, those with lower baseline severity and organ dysfunction, and those without etiologic diagnosis or bacteremia. The cumulative dosage of corticosteroids had no significant effect on the risk of death, but bacterial burden upon diagnosis was higher in patients receiving steroid therapy. Conclusions: In critically-ill patients, systemic corticosteroids should be used very cautiously because this treatment is strongly associated with increased risk of death in patients with intensive care unit acquired pneumonia, particularly in the absence of established indications and in patients with lower baseline severity. Decreased inflammatory response may result in delayed clinical suspicion of intensive care unit acquired pneumonia and higher bacterial count. (Crit Care Med 2012; 40:2552-2561)

The Role of Keratinized Mucosa in Peri-Implant Health

Objective: To evaluate the role of keratinized mucosa around dental implants, correlating with other clinical parameters related to the success of dental implants. Design: Cross-section. Setting: Institutional tertiary referral hospital. Patients: A total of 202 dental implants fixed in the cleft area of 109 patients with cleft lip and/or palate were evaluated. Interventions: The evaluated clinical parameters were probing depth and gingival and plaque indexes on the buccal surface (three sites). Main Outcome Measures: All clinical parameters were correlated with the width of keratinized mucosa around the implants. Results: The largest probing depths were detected when the width of keratinized mucosa was 2 mm or more, with a statistically significant difference between the means of the probing depth and keratinized mucosa width. Conclusion: Even though the present results suggest that peri-implant health can be observed in areas with keratinized mucosa width under 2 mm provided an adequate oral hygiene control is performed, longitudinal randomized studies are necessary to analyze the relationship between the width of keratinized mucosa and the health of peri-implant tissues.

Prevalence of depression and anxiety disorders in hospitalized patients at the dermatology clinical ward of a university hospital

BACKGROUND: The objective of this study was to estimate the prevalence of depression and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in Sao Paulo, Brazil. OBJECTIVE: To assess the prevalence of mood and anxiety disorders in hospitalized patients at the dermatology ward at a university hospital in Sao Paulo. METHOD: A total of 75 patients, men and women, aged between 18 and 76 years, took part in the research. The study employed a descriptive, cross sectional and correlational method. The data was collected by means of a social demographic questionnaire and the PRIME-MD. RESULTS: It was found that 45.3 percent of the subjects presented with depressive symptoms, and 52 percent presented with symptoms of anxiety and that this survey showed moderate and high significant correlations (p<0,01; r= 0,616) for depression and anxiety. CONCLUSION: These facts could evidence the relationship between physical and psyche, just as the literature presents.

Current practices in the management of patients with ureteral calculi in the emergency room of a university hospital

OBJECTIVE: Urinary lithiasis is a common disease. The aim of the present study is to assess the knowledge regarding the diagnosis, treatment and recommendations given to patients with ureteral colic by professionals of an academic hospital. MATERIALS AND METHODS: Sixty-five physicians were interviewed about previous experience with guidelines regarding ureteral colic and how they manage patients with ureteral colic in regards to diagnosis, treatment and the information provided to the patients. RESULTS: Thirty-six percent of the interviewed physicians were surgeons, and 64% were clinicians. Forty-one percent of the physicians reported experience with ureterolithiasis guidelines. Seventy-two percent indicated that they use noncontrast CT scans for the diagnosis of lithiasis. All of the respondents prescribe hydration, primarily for the improvement of stone elimination (39.3%). The average number of drugs used was 3.5. The combination of nonsteroidal anti-inflammatory drugs and opioids was reported by 54% of the physicians (i. e., 59% of surgeons and 25.6% of clinicians used this combination of drugs) (p = 0.014). Only 21.3% prescribe alpha blockers. CONCLUSION: Reported experience with guidelines had little impact on several habitual practices. For example, only 21.3% of the respondents indicated that they prescribed alpha blockers; however, alpha blockers may increase stone elimination by up to 54%. Furthermore, although a meta-analysis demonstrated that hydration had no effect on the transit time of the stone or on the pain, the majority of the physicians reported that they prescribed more than 500 ml of fluid. Dipyrone, hyoscine, nonsteroidal anti-inflammatory drugs, and opioids were identified as the most frequently prescribed drug combination. The information regarding the time for the passage of urinary stones was inconsistent. The development of continuing education programs regarding ureteral colic in the emergency room is necessary.

Blood transfusion in cardiac surgery is a risk factor for increased hospital length of stay in adult patients

Abstract Background Allogeneic red blood cell (RBC) transfusion has been proposed as a negative indicator of quality in cardiac surgery. Hospital length of stay (LOS) may be a surrogate of poor outcome in transfused patients. Methods Data from 502 patients included in Transfusion Requirements After Cardiac Surgery (TRACS) study were analyzed to assess the relationship between RBC transfusion and hospital LOS in patients undergoing cardiac surgery and enrolled in the TRACS study. Results According to the status of RBC transfusion, patients were categorized into the following three groups: 1) 199 patients (40%) who did not receive RBC, 2) 241 patients (48%) who received 3 RBC units or fewer (low transfusion requirement group), and 3) 62 patients (12%) who received more than 3 RBC units (high transfusion requirement group). In a multivariable Cox proportional hazards model, the following factors were predictive of a prolonged hospital length of stay: age higher than 65 years, EuroSCORE, valvular surgery, combined procedure, LVEF lower than 40% and RBC transfusion of > 3 units. Conclusion RBC transfusion is an independent risk factor for increased LOS in patients undergoing cardiac surgery. This finding highlights the adequacy of a restrictive transfusion therapy in patients undergoing cardiac surgery. Trial registration Clinicaltrials.gov identifier: http://NCT01021631.
