          Abstract

          Recent original scientific contributions published in selected Brazilian periodicals and classifiable under cardiovascular and pulmonary subject categories cover a wide range of sub specialties, both clinical and exprimental. Because they appear in journals with only recently enhanced visibility, we have decided to highlight a number of specific items appeared in four Brazilian journals, because we understand that this is an important subsidy to keep our readership adequately informed. These papers cover extensive sub-areas in both fields.

          Complications that increase the time of Hospitalization at ICU of patients submitted to cardiac surgery.

          To show the complications that increase the permanence at intensive care unit (ICU) of the patients submitted to cardiac surgery. Eighty-five handbooks of patients submitted to cardiac surgery had been analyzed, retrospectively, from March to May 2009 at Santa Casa de Misericórdia de Juiz de Fora (MG)--Brazil--and 14 (16.47%) patients had been studied. They remained more than 5 days at ICU. In 85 patients occurred three deaths: two patients operated in urgency character and this increases the morbidity; one patient who remained in mechanical ventilation (MV) by 21 days. Complications that had increased the time of hospitalization at ICU had been respiratory and metabolic in accordance with literature. Complications that increase the time of permanence at ICU are those related to respiratory function, chronic obstructive pulmonary disease, tabagism, pulmonary congestion, time of permanence under MV, diabetes, infections, renal insufficiency, stroke and hemodynamic instability.

            Pharmaceutical care for patients with persistent asthma: assessment of treatment compliance and use of inhaled medications.

            To evaluate treatment compliance and use of inhaled medications of patients with asthma receiving complementary pharmaceutical care. A controlled prospective parallel study involving a study group and a control group. We selected 60 patients with persistent asthma and using metered-dose inhalers (MDIs), dry powder inhalers (DPIs) or both. The patients were evaluated three times over 60 days. Instructions were provided to the patients in the study group at all visits but only at the first visit to those in the control group. The patients using 120% of the total number of prescribed doses were classified as noncompliant. The inhalation technique was quantified by a scoring system. A satisfactory technique was defined as a score higher than 7 (maximum, 9) for MDIs and higher than 4 (maximum, 5) for DPIs. The final study sample comprised 28 study group patients and 27 control group patients, of whom 18 (64.3%) and 20 (74.7%), respectively, were considered treatment compliant. From the first to the third visits, there were increases, in the study and control groups, in the median MDI-use score (from 3 [range, 0-5] to 8 [range, 8-9]; p < 0.001; and from 5 [range, 2-6] to 7 [range, 6-8]), as well as in the median DPI-use score (from 3 [range, 2-4] to 5 [range, 4-5] and from 3 [range, 2-4] to 4 [range, 3-5]). The counseling provided by the pharmacist to the patient was important to assist in the implementation of the appropriate inhalation technique, especially for MDI use.

              Increased risk of respiratory symptoms and chronic bronchitis in women using biomass fuels in Nigeria.

              To determine whether respiratory symptoms and chronic bronchitis are associated with the use of biomass fuels (BMFs) among women residing in rural areas of the Ekiti State, in southwestern Nigeria. From January to June of 2009, we carried out a cross-sectional study including 269 adult women. To collect data on sociodemographic status, type of fuel used for cooking in the household, respiratory symptoms, and smoking history, we used a questionnaire adapted from the European Community Respiratory Health Survey. All of the participants were invited to undergo spirometry. Of the 269 women in the study, 161 (59.9%) used BMFs for cooking. The proportion of women who reported respiratory symptoms was greater among those using BMFs than among those using a non-BMF-cough (13.7% vs. 3.7%); wheezing (8.7% vs. 2.8%); chest pain (7.5% vs. 1.9%); breathlessness (11.8% vs. 6.5%); nasal symptoms (9.3% vs. 4.6%); and chronic bronchitis (10.6% vs. 2.8%). Multivariate logistic regression analysis revealed that the use of BMFs was associated with the following variables: cough (OR = 4.82; p = 0.01); chronic bronchitis (OR = 3.75; p = 0.04); wheezing (OR = 2.22; p = 0.23); chest pain (OR = 3.82; p = 0.09); breathlessness (OR = 1.54; p = 0.35); and nasal symptoms (OR = 2.32; p = 0.20). All of the spirometric parameters evaluated (FEV1, FVC, FEV1/FVC ratio, and PEF) were lower in the women using BMFs than in those using a non-BMF. Our results underscore the need for women using BMFs in their households to replace them with a nontoxic type of fuel, such as electricity or gas.
