Tuberculous meningitis in HIV-infected patients in Brazil: clinical and laboratory characteristics and factors associated with mortality

Background: Tuberculous meningitis (TBM) is a growing problem in HIV-infected patients in developing countries, where there is scarce data about this co-infection. Our objectives were to analyze the main features and outcomes of HIV-infected patients with TBM. Methods: This was a retrospective study of HIV-infected Brazilian patients admitted consecutively for TBM. All patients had Mycobacterium tuberculosis isolated from the cerebrospinal fluid (CSF). Presenting clinical and laboratory features were studied. Multivariate analysis was used to identify variables associated with death during hospitalization and at 9 months after diagnosis. Survival was estimated using the Kaplan-Meier method. Results: We included 108 cases (median age 36 years, 72% male). Only 15% had fever, headache, and meningeal signs simultaneously. Forty-eight percent had extrameningeal tuberculosis. The median CD4+ cell count was 65 cells/mu l. Among 90 cases, 7% had primary resistance to isoniazid and 9% presented multidrug-resistant strains. The overall mortality during hospitalization was 29% and at 9 months was 41%. Tachycardia and prior highly active antiretroviral therapy (HAART) were associated with 9-month mortality. The 9-month survival rate was 22% (95% confidence interval 12-43%). Conclusions: Clinical and laboratory manifestations were unspecific. Disseminated tuberculosis and severe immunosuppression were common. Mortality was high and the 9-month survival rate was low. Tachycardia and prior HAART were associated with death within 9 months of diagnosis. (C) 2009 International Society for Infectious Diseases. Published by Elsevier Ltd. All rights reserved.

Treatment of suicidal people around the world

Background Suicide is a leading cause of death worldwide; however, little information is available about the treatment of suicidal people, or about barriers to treatment. Aims To examine the receipt of mental health treatment and barriers to care among suicidal people around the world. Method Twenty-one nationally representative samples worldwide (n=55 302; age 18 years and over) from the World Health Organization`s World Mental Health Surveys were interviewed regarding past-year suicidal behaviour and past-year healthcare use. Suicidal respondents who had not used services in the past year were asked why they had not sought care. Results Two-fifths of the suicidal respondents had received treatment (from 17% in low-income countries to 56% in high-income countries), mostly from a general medical practitioner (22%), psychiatrist (15%) or non-psychiatrist (15%). Those who had actually attempted suicide were more likely to receive care. Low perceived need was the most important reason for not seeking help (58%), followed by attitudinal barriers such as the wish to handle the problem alone (40%) and structural barriers such as financial concerns (15%). Only 7% of respondents endorsed stigma as a reason for not seeking treatment. Conclusions Most people with suicide ideation, plans and attempts receive no treatment. This is a consistent and pervasive finding, especially in low-income countries. Improving the receipt of treatment worldwide will have to take into account culture-specific factors that may influence the process of help-seeking.

Hemostatic changes and clinical sequelae after on-pump compared with off-pump coronary artery bypass surgery: a prospective randomized study

Objective To delineate the effects of extracorporeal bypass on biomarkers of hemostasis, fibrinolysis, and inflammation and clinical sequelae. Methods Patients were assigned prospectively and randomly to either on-pump (n=41) or off-pump (n=51) coronary bypass surgery. The concentrations of C-reactive protein, fibrinogen, D-dimer, and plasminogen activator inhibitor type-1 in blood were quantified before and after (1 and 24 h) surgery. Similar surgical and anesthetic procedures were used for both groups. Clinical events were assessed during initial hospitalization and at the end of I year. Results The concentrations of plasminogen activator inhibitor type-1 and D-dimer were greater compared with preoperative values 1 and 24 h after surgery in both groups, but their concentrations increased to a greater extent 24 h after surgery in the on-pump group (P<0.01). The concentration of C-reactive protein did not change appreciably immediately after surgery in either group but increased in a parallel manner 24 h after either on-pump or off-pump surgery (P<0.01). Bypass surgery in the on-pump group was associated with greater blood loss during surgery and more bleeding after surgery (P <= 0.01). The incidence of all other complications was similar in the two groups. Conclusion On-pump surgery was associated with biochemical evidence of a prothrombotic state early after surgery but no greater incidence of thrombotic events was observed. The prothrombotic state might be a consequence of extracorporeal bypass, compensation in response to more bleeding, or both in patients undergoing on-pump surgery.

Importance of psychological intervention for the recovery of children submitted to elective surgery

Purpose: The effects of anxiety on the patient and his/her family are known to be the main factors that influence health recovery in child surgery. When the whole family can be prepared and supported by psychologic intervention, the damage to child behavior and family anxiety is attenuated. Methods: This study was conducted in children between 2 and 6 years old, divided into 2 groups of 10 pairs each. The experimental group received psychologic intervention, whereas the control group did not. One month after the surgery, they were reevaluated and compared with the same instruments used in the beginning of the study. The instruments used were as follows: the State-Trait Anxiety Inventory with the mothers and the Rutter`s Child Behavior A2 Scale and the Posthospital Behavior Questionnaire with the children. Results: The results were compared by the Wilcoxon and Mann-Whitney nonparametric tests for independent samples, both at the P <.05 significance levels. Mothers stated that anxiety was different in the postsurgery period, showing a significant decrease when comparing the experimental and control groups. Both instruments to measure child behavior also showed that prepared children had less habit changes than the control group, which showed increased levels of inadequate behavior. Conclusions: These data confirm reports in literature regarding child preparation before medical intervention and reinforces the importance of specialized presurgery planning procedures by the proper professional interfaced with the surgical colleagues, all aiming toward the best recovery for the children.

Coping by relatives of critical care patients

OBJECTIVE: To describe the coping strategies used by the relatives of patients hospitalized in an intensive care unit. METHODS: This is a descriptive study that uses a convenience sample and both qualitative and quantitative methods. The study was conducted at a tertiary university hospital in Brazil. Participants included 41 relatives who were selected during the first 96 hours of patient hospitalization in the intensive care unit. RESULTS: The participants reported that they more frequently used Coping Strategies Based on the Stressor, followed by Religiosity/Fantasy Thinking and Seeking for Social Support. There was a statistically significant relationship (P <.01) between the use of the strategy Seeking for Social Support and elevated Acute Physiology, Age, and Chronic Health Evaluation 11 scores. Qualitative analysis allowed a clearer understanding of the relation between the patient`s condition and changes in the coping strategies used by the patient`s relatives. CONCLUSION: This study describes the coping strategies used by patients` relatives during the early hospitalization period. This investigation allowed for a better understanding of the relatives` psychologic aspects and their relation with the patient`s clinical condition. The results shall assist the design of specific interventions directed at facilitating positive coping responses on the part of relatives. (Heart Lung (R) 200 38:217-227.)

HbA(1c) as a risk factor for heart failure in persons with diabetes: the Atherosclerosis Risk in Communities (ARIC) study

Heart failure (HF) incidence in diabetes in both the presence and absence of CHD is rising. Prospective population-based studies can help describe the relationship between HbA(1c), a measure of glycaemia control, and HF risk. We studied the incidence of HF hospitalisation or death among 1,827 participants in the Atherosclerosis Risk in Communities (ARIC) study with diabetes and no evidence of HF at baseline. Cox proportional hazard models included age, sex, race, education, health insurance status, alcohol consumption, BMI and WHR, and major CHD risk factors (BP level and medications, LDL- and HDL-cholesterol levels, and smoking). In this population of persons with diabetes, crude HF incidence rates per 1,000 person-years were lower in the absence of CHD (incidence rate 15.5 for CHD-negative vs 56.4 for CHD-positive, p < 0.001). The adjusted HR of HF for each 1% higher HbA(1c) was 1.17 (95% CI 1.11-1.25) for the non-CHD group and 1.20 (95% CI 1.04-1.40) for the CHD group. When the analysis was limited to HF cases which occurred in the absence of prevalent or incident CHD (during follow-up) the adjusted HR remained 1.20 (95% CI 1.11-1.29). These data suggest HbA(1c) is an independent risk factor for incident HF in persons with diabetes with and without CHD. Long-term clinical trials of tight glycaemic control should quantify the impact of different treatment regimens on HF risk reduction.

The Association of Hemoglobin A1c With Incident Heart Failure Among People Without Diabetes: The Atherosclerosis Risk in Communities Study

OBJECTIVE-This study sought to investigate an association of HbA1c (A1C) with incident heart failure among individuals without diabetes and compare it to fasting glucose. RESEARCH DESIGN AND METHODS-We studied 11,057 participants of the Atherosclerosis Risk in Communities (ARIC) Study without heart failure or diabetes at baseline and estimated hazard ratios of incident heart failure by categories of A1C (<5.0, 5.0-5.4 [reference], 5 5-59, and 6.0-6.4%) and fasting glucose (<90, 90-99 [reference], 100-109, and 110-125 mg/dl) using Cox proportional hazards models. RESULTS-A total of 841 cases of incident heart failure hospitalization or deaths (International Classification of Disease, 9th/10th Revision, 428/150) occurred during a median follow-up of 14.1 years (incidence rate 5.7 per 1,000 person-years). After the adjustment for covariates including fasting glucose, the hazard ratio of incident heart failure was higher in individuals with A1C 6.0-6.4% (1.40 [95% CI, 1 09-1.79]) and 5.5-6.0% (1.16 [0.98-1 37]) as compared with the reference group. Similar results were observed when adjusting for insulin level or limiting to heart failure cases without preceding coronary events or developed diabetes during follow-up. In contrast, elevated fasting glucose was not associated with heart failure after adjustment for covariates and A1C. Similar findings were observed when the top quartile (A1C, 5.7-6.4%, and fasting glucose, 108-125 mg/dl) was compared with the lowest quartile (<5 2% and <95 mg/dl, respectively). CONCLUSIONS-Elevated A1C (>= 5.5-6 0%) was associated with incident heart failure in a middle-aged population without diabetes, suggesting that chronic hyperglycemia prior to the development of diabetes contributes to development of heart failure.

Giant prolapsed submucous leiomyoma: a surgical challenge for gynecologists

We present a case of a 45-year-old woman who presented with irregular vaginal bleeding and menorrhagia for two months, with an episode of massive bleeding initiating 24 hours before with hemodynamic shock. Vaginal inspection showed a soft, rounded, friable mass in vaginal introitus. After hospitalization, blood transfusion and hydration, she was submitted to vaginal myomectomy with the withdrawal of a 12-cm white, solid, huge, pedunculated, leiomyoma; however, hysterectomy was performed due to persistent uterine bleeding. The postoperation period had no complications. Macroscopy showed a retraction of the myoma pedicle. Gynecologists should prioritize clamping of a pedicle before surgery, reducing its size if the tumor is large.

ANXIETY, DYSPHORIA, AND DEPRESSION SYMPTOMS IN MOTHERS OF PRETERM INFANTS

To compare presence and severity of clinical symptoms of anxiety, dysphoria, and depression in mothers of preterm and of full-term infants and to observe changes in symptoms of mothers of preterm infants during hospitalization of the infants and after discharge, 50 mothers of preterm infants and 25 mothers of full-term infants completed the State-Trait Anxiety Inventory and the Beck Depression Inventory. The mothers with preterm infants had significantly higher clinical symptoms of State Anxiety during hospitalization than the group with full-term infants, but the clinical symptoms of anxiety in mothers of preterm infants decreased significantly after discharge. The health staff in a neonatal intensive care unit should not only be aware of infants` clinical status but also of the mothers` emotional state.

Hospitalizations for HIV/AIDS: Differences Between Sexes

Background: Women are especially vulnerable to HIV infection because of biological, social, cultural, and economic factors. In Brazil, AIDS was initially seen predominantly in homosexual men, but the epidemic gradually reached a gender balance as increasing numbers of women became infected with HIV. Objective: The aim of the present study was to identify the clinical and epidemiologic characteristics of hospitalized patients with HIV/AIDS of both sexes and compare the differences between them. Methods: This epidemiologic cross-sectional study evaluated gender differences in demographic, social, clinical, and epidemiologic characteristics of patients diagnosed with HIV/AIDS who were admitted for any reason to the Public Hospital of the Medical School of the Federal University of Triangulo Mineiro, Uberaba, Minas Gerais State, Brazil. Results: A total of 363 patients were included in the analysis, with a male/female ratio of 1.1:1.0. Forty-one percent of women were pregnant. Mean age at hospitalization and duration of hospitalization were significantly greater among men (P < 0.05). Men and nonpregnant women were admitted because of infection significantly more often than were pregnant women (P < 0.05). Significantly more single men who reported homosexual, bisexual, or heterosexual behavior associated with drug use were admitted compared with women (P < 0.05). Women admitted for treatment were significantly more likely than men to be employed (P < 0.05). Adherence to antiretroviral treatment and T CD4+ lymphocyte count indicated important differences between the sexes, with better parameters observed among nonpregnant and pregnant women compared with men. Conclusions: In the present study, women with HIV/AIDS who were admitted to the hospital for any reason were in better clinical condition compared with men. This observation may be partially explained by the proportion of pregnant women in the study population. These findings suggest that future studies should examine pregnant women with HIV/AIDS as a separate population group to avoid bias in analysis.

Effect of Oral Hygiene with 0.12% Chlorhexidine Gluconate on the Incidence of Nosocomial Pneumonia in Children Undergoing Cardiac Surgery

OBJECTIVE. To evaluate the effect of oral hygiene with 0.12% chlorhexidine gluconate on the incidence of nosocomial pneumonia and ventilator-associated pneumonia (VAP) in children undergoing cardiac surgery. DESIGN. Prospective, randomized, double-blind, placebo-controlled trial. SETTING. Pediatric intensive care unit (PICU) at a tertiary care hospital. patients. One hundred sixty children undergoing surgery for congenital heart disease, randomized into 2 groups: chlorhexidine (n = 87) and control (n = 73). INTERVENTIONS. Oral hygiene with 0.12% chlorhexidine gluconate or placebo preoperatively and twice a day postoperatively until PICU discharge or death. RESULTS. Patients in experimental and control groups had similar ages (median, 12.2 vs 10.8 months; P =. 72) and risk adjustment for congenital heart surgery 1 score distribution (66% in category 1 or 2 in both groups; P =. 17). The incidence of nosocomial pneumonia was 29.8% versus 24.6% (Pp. 46) and the incidence of VAP was 18.3% versus 15% (Pp. 57) in the chlorhexidine and the control group, respectively. There was no difference in intubation time (P =. 34), need for reintubation (P =. 37), time interval between hospitalization and nosocomial pneumonia diagnosis (P =. 63), time interval between surgery and nosocomial pneumonia diagnosis (P =. 10), and time on antibiotics (P =. 77) and vasoactive drugs (P =. 16) between groups. Median length of PICU stay (3 vs 4 days; P =. 53), median length of hospital stay (12 vs 11 days; P =. 67), and 28-day mortality (5.7% vs 6.8%; P =. 77) were also similar in the chlorhexidine and the control group. CONCLUSIONS. Oral hygiene with 0.12% chlorhexidine gluconate did not reduce the incidence of nosocomial pneumonia and VAP in children undergoing cardiac surgery.

Maternal Anxiety and Depression and Development of Prematurely Born Infants in the First Year of Life

The Purpose of this study was: (a) to assess and to compare anxiety and depression symptoms in mothers of preterm neonates during hospitalization in the Neonatal Intenive Care Unit, after discharge, and at the end of the infants` first year of life and (b) to assess the child`s development at 12 months of chronological corrected age (CCA). Thirty-six mothers, with no psychiatric antecedents assessed with the SCID-NP were evaluated by STAI and BDI The infants were assessed with Bayley-II Scales. There was a significant decrease in clinical symptoms of state-anxiety in mothers (p =.008). comparing the period during hospitalization and after discharge of the infants. Clinical symptoms of anxiety and depression were observed in 20% of the mothers at the end of the infants` first year of age. The majority of the infants exhibited normal development on Bayley-II at 12 months CCA: however. 25% of the infants displayed cognitive problems and 40% motor problems. The mothers` anxiety and depression symptoms decreased it the end of the first year of life of the pre-term infants and the children showed predominately normal development Lit this phase.

The characteristics of NDM-producing Klebsiella pneumoniae from Canada

After recent hospitalization in India (New Delhi and Mumbai), 2 patients, on their return to Canada, presented with lower urinary tract infections due to multiresistant Klebsiella pneumoniae that produced New Delhi metall-beta-lactamase and CTX-M-15. The organisms belonged to clones ST147 and ST340, and were positive for aac(6`)-Ib-cr, as well as for the ccdAB and vagCD addiction systems. The bla(NDM) plasmid was located on the IncFIIA and IncA/C replicon groups of plasmids. Clones ST147 and ST340 are also responsible for harbouring bla(KPC), and it is possible that they played an important role in the intercontinental spread of antimicrobial resistance.

Nutrition Therapy in a Pediatric Intensive Care Unit: Indications, Monitoring, and Complications

Background: Nutrition therapy (NT) is essential for the care of critically ill children. Inadequate feeding leads to malnutrition and may increase the patient`s risk of morbidity and mortality. The aim of this study was to describe the NT used in a tertiary pediatric intensive care unit (PICU). Methods: The authors evaluated NT administered to 90 consecutive patients who were hospitalized for 7 days in the PICU of Instituto da Crianca, Hospital das Clinicas, Universidade de Sao Paulo, Brazil. NT was established according to the protocol provided by the institution`s NT team. NT provided a balance of fluids and nutrients and was monitored with a weekly anthropometric nutrition assessment and an evaluation of complications. Results: NT was initiated, on average, within 72 hours of hospitalization. Most children (80%) received enteral nutrition (EN) therapy; of these, 35% were fed orally and the rest via nasogastric or postpyloric tube. There were gastrointestinal complications in patients (5%) who needed a postpyloric tube. Parenteral nutrition (PN) was used in only 10% of the cases, and the remaining 10% received mixed NT (EN + PN). The average calorie and protein intake was 82 kcal/kg and 2.7 g/kg per day. Arm circumference and triceps skinfold thickness decreased. Conclusions: The use of EN was prevalent in the tertiary PICU, and few clinical complications occurred. There was no statistically significant change in most anthropometric indicators evaluated during hospitalization, which suggests that NT probably helped patients maintain their nutrition status.

Clinical and Fiberoptic Endoscopic Evaluation of Swallowing in Robin Sequence Treated With Nasopharyngeal lntubation: The Importance of Feeding Facilitating Techniques

Objective: To evaluate oral feeding capacity, the swallowing process, and risk for aspiration, both clinically and during fiberoptic endoscopic evaluation of swallowing, in infants with isolated Robin sequence treated exclusively with nasopharyngeal intubation and feeding facilitating techniques. Design: Longitudinal and prospective study. Setting: Hospital de Reabilitacao de Anomalies Craniofaciais, University of Sao Paulo, Bauru, Brazil. Patients: Eleven infants with isolated Robin sequence, under 2 months of age, treated with nasopharyngeal intubation. Interventions: Feeding facilitating techniques were applied in all infants throughout the study period. The infants were evaluated clinically and through fiberoptic endoscopic evaluation of swallowing at first, second, and, if necessary, third week of hospitalization (T1, T2, T3). The mean volume of ingested milk was registered during clinical evaluation, and events were registered during feeding. Results: The respiratory status of all infants was improved after nasopharyngeal intubation; 72% of them presented risk for aspiration during fiberoptic endoscopic evaluation of swallowing at T1. This risk was less frequent when thickened milk was given to the infants and at subsequent evaluations (T2 and T3). Conclusions: Nasopharyngeal intubation aids in stabilizing the airway in isolated Robin sequence, but it does not relate directly to feeding. The risk for aspiration was present in most of the infants, mainly during the first week of hospitalization, and improved within a few weeks, after the use of feeding facilitating techniques.
