RESUMO

BACKGROUND: To evaluate the role of the quality improvement course (QIC) to reduce the caesarean section (CS) rate among nulliparas (Robson groups 1 and 2) and to find out which group of women have reduced the CS rate following attendance at the course. METHODS: The QIC was organized in 2015. For the evaluation of the CS rate after the OIC, deliveries from the selected hospitals in 2014 and 2016 were compared using MS EXCEL and SPSS 23.0. RESULTS: Nulliparas accounted for 44.6% (3585/8046) and 42.9% (3628/8460) of all the deliveries in 2014 and 2016 years, respectively. The CS rate among nulliparas decreased from 19.0% (665/3502) in 2014 to 16.8% (593/3526) in 2016 (p = 0.018). The greatest decrease in absolute contribution to the overall CS rate was recorded in group 1 (p = 0.08). Perinatal mortality was 3.1 in 2014 and 3.9 in 2016 per 1000 deliveries (p = 0.569). CONCLUSION: The QIC has helped to reduce the CS rate among nulliparas without a negative influence on perinatal mortality. The greatest decrease in the overall CS rate was recorded among nulliparous women who were treated with oxytocin and managed to reach a full cervical dilatation.

RESUMO

BACKGROUND: To evaluate the role of the TGCS to reduce the caesarean section (CS) rate among nulliparas (Robson groups 1 and 2) and to find out which group of women have reduced the CS rate by using this tool. METHODS: The Robson classification was introduced in Lithuanian hospitals prospectively classifying all the deliveries in 2012. The CS rate overall and in each Robson group was calculated and the results were discussed. The analysis was repeated in 2014 and the data from the selected hospitals were compared using MS EXCEL and SPSS 23.0. RESULTS: Nulliparas accounted for 43% (3746/8718) and 44.6% (3585/8046) of all the deliveries in 2012 and 2014 years, respectively. The CS rate among nulliparas decreased from 23.9% (866/3626) in 2012 to 19.0% (665/3502) in 2014 (p < 0.001).The greatest decrease in absolute contribution to the overall CS rate was recorded in groups 1 (p = 0.005) and 2B (p < 0.001). Perinatal mortality was 3.5 in 2012 and 3.1 in 2014 per 1000 deliveries (p = 0.764). CONCLUSION: The TGCS can work as an audit intervention that could help to reduce the CS rate without a negative impact on perinatal mortality.

RESUMO

BACKGROUND: To determine the cesarean section (CS) rate in Lithuania, identify the groups of women that influence it using the Robson classification and to determine the impact of implementing the use of the Robson classification on the CS rate. METHODS: The Robson classification was introduced in Lithuanian hospitals prospectively classifying all the deliveries in 2012. The overall CS rate, sizes of the Robson groups of women, CS rate in each group and contribution to the overall CS rate from each group was calculated and the results were discussed. The analysis was repeated in 2014 and the data were compared using MS EXCEL and SPSS 23.0. RESULTS: Nineteen Lithuanian hospitals participated in the study. They represented 84.1% of the deliveries (23,742 out of 28,230) in 2012 and 88.5% of the deliveries (24,653 out of 27,872) in 2014. The CS rate decreased from 26.9% (6379/23,742) in 2012 to 22.7% (5605/24,653) in 2014 (p < 0.001). The greatest contributions to the overall CS rate were made by groups 1, 2 and 5. The greatest decrease in the CS rate was detected in group 2. The absolute contribution to the overall CS rate decreased from 4.9% to 3.8%. CONCLUSION: The Robson classification can work as an audit tool to identify the groups that have the greatest impact on the CS rate. It also helps to develop a strategy focussing on the reduction of the CS rate.

RESUMO

BACKGROUND AND OBJECTIVES: There are only few training programs in obstetric emergencies currently in use and only some of them were evaluated with an adequate sample of participants. Therefore, we present the evaluation of the novel Standardized Trainings in Obstetrical Emergencies (STrObE), conducted in Lithuania. The aim of this study was to analyze whether participants' self-reported knowledge and confidence increased after the trainings, and whether the impact of the trainings was long-lasting. MATERIALS AND METHODS: Data was collected across the majority of hospitals providing secondary and tertiary obstetrical care in Lithuania in 2015. A total of 650 obstetricians-gynecologists and midwives attended the trainings; 388 (response rate 59.7%) of them filled in the initial questionnaire before the trainings, 252 (64.9%) immediately after, 160 (41.2%) 6 weeks after, and 160 (41.2%) 6 months after the trainings, which was the final sample for the analyses. Participants used a Likert-type scale to evaluate their knowledge and confidence about management of urgent obstetrical situations: vacuum-assisted vaginal delivery, shoulder dystocia, postpartum hemorrhage, preeclampsia/eclampsia, early preterm labor, and dystocia. We assessed how participants' self-reported knowledge and confidence changed after the trainings (compared to before the trainings) and how long the effect was retained for. RESULTS: The mean score of self-reported knowledge in obstetrical emergencies increased immediately after the trainings comparing to the scores before the trainings (P<0.001) and it did not differ further between the three time points after the trainings (i.e. immediately, 6 weeks, and 6 months; P>0.05). The same pattern was observed for self-reported confidence scores. The increase in self-reported knowledge and confidence after the trainings was stable. Moreover, the self-reported knowledge and confidence gains were greater for those participants with lower work experience, although benefit was seen across all experience levels. CONCLUSIONS: STrObE improved participants' self-reported knowledge and confidence and lasting positive effects were observed for at least 6 months after the initial trainings. Moreover, the trainings were more beneficial for those with lower work experience, although they benefited all the participants.

RESUMO

BACKGROUND: Postpartum haemorrhage (PPH) remains one of the most common causes of maternal morbidity and mortality. Therefore, clearly written PPH management guidelines should be used in clinical practice. The aim of this study was to evaluate the effectiveness of the implementation of PPH management guidelines at the First Regional Perinatal Centre of Southern Kazakhstan (FRPC). METHODS: Between 2012 and 2013 an interventional study was performed whereby the PPH management guidelines were implemented at the FRPC. All of the deliveries that were complicated by PPH 8 months before and 8 months after the intervention were analysed. Prevalence and severity of PPH, and the change in prevention, diagnostics and management of PPH was evaluated and statistical analysis using the SPSS 22.0 was performed. RESULTS: There were in total 5404 and 5956 deliveries in the pre- and post-intervention periods, respectively. The rates of PPH and severe PPH decreased from 1.17 to 1.02 % (p = 0.94) and from 0.24 to 0.22 % (p = 0.94), respectively. Blood loss on average increased from 1055 to 1170 ml in the post-intervention period. The pharmacological treatment of postpartum haemorrhage with uterotonics was administered most frequently during both periods. After the implementation of the guidelines, the number of transfused units of packed red blood cells decreased from 4.76 to 2.48 units/case. In addition, the amount of transfused fresh frozen plasma decreased by 20 %. The number of conservative interventions and conservative operations increased from 7.9 to 52.7 % and from 3.9 to 48.6 %, respectively. The number of hysterectomies decreased from 23.7 % in pre-intervention to 8.1 % in the post-intervention period. CONCLUSIONS: The implementation of the PPH management guidelines had a positive effect on PPH prevention, diagnostics and management. It led to a more conservative aproach to the treatment of PPH. Therefore, clearly written PPH management guidelines, adapted for a particular hospital, should be developed and used in clinical practice.

RESUMO

Postpartum haemorrhage (PPH) is an urgent obstetric condition requiring an immediate response and a multidisciplinary approach. The aim of this study was to review PPH management guidelines implemented in clinical practice, to evaluate their impact regarding prevention, diagnosis and treatment, and to analyze how the numbers of PPH cases changed in the post-intervention period. A systematic search in the PubMed database was performed. The references of all included articles were examined. Studies evaluating the management of PPH and the impact on the numbers of cases of this pathology after the implementation of new or updated guidelines were involved in the analysis. Two reviewers independently examined the titles and abstracts of all identified citations, selected potentially eligible studies, and evaluated their full-text versions. Methodological quality was assessed using a checklist based on the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement. We analyzed seven articles that evaluated the impact of new or updated guidelines for PPH management implemented in clinical practice. In four trials, the numbers of PPH cases declined after the intervention. Guidelines for PPH management can have a positive impact on the reduction of the number of PPH cases.

RESUMO

A survey of statistical methods for validation of shape-scale families of probability distributions from type II censored samples is given. We propose "integrated likelihood ratio tests" which are modifications of Zhang's tests from complete to type II censored data. We also give modifications of Cramér-von-Mises and Anderson-Darling tests using integration with respect to non-parametric estimators of the cumulative distribution function. Explicit formulas for modified chi-squared tests from censored data with data driven choice of partitioning are given. Powers of tests against most used alternatives to the Weibull, loglogistic and lognormal distribution are compared.

RESUMO

BACKGROUND: Associations between nasal and bronchial impairment have been repeatedly described in chronic obstructive pulmonary disease (COPD), whereas nasal mucociliary clearance (MCC) in COPD patients is not yet fully understood. We studied nasal MCC parameters in COPD patients and compared them with healthy adults (HA) and with cystic fibrosis (CF) patients with compromised MCC. METHODOLOGY: An observational study of 98 COPD ex-smokers and subjects from control groups evaluated for nasal MCC time (NMCCt) and by digital video microscopy of nasal mucosa recording ciliary beat frequency (CBF) and ciliary beat pattern. RESULTS: The NMCCt was decreased in HA compared to those with COPD and decreased in those with COPD compared to those with CF. CBF in COPD was lower compared to HA. The index of ciliary dyskinesia in COPD patients differed from HA. We detected higher NMCCt and lower nasal CBF in patients with chronic bronchitis phenotype (CB) compared to non-CB patients. CONCLUSIONS: We confirmed the presence of impaired nasal MCC in COPD ex-smokers. These impairments were apparent predominantly in the CB phenotype.

RESUMO

BACKGROUND AND AIM: This study was carried out to assess relationship between quality of life (QoL) and disease severity expressed by multifactorial prognostic index (BODE) in ex-smokers suffering from chronic obstructive pulmonary disease (COPD), minimally 8 weeks free of exacerbation. MATERIALS AND METHODS: The evaluation was performed in 98 randomly recruited COPD patients enrolled into a cross-sectional, observational CILIARY study at the Department of Pneumology, Charles University, Faculty of Medicine in Hradec Králové. In them, quality of life evaluation using the SGRQ questionnaire and the BODE index calculation was performed. We statistically compared interrelationship between BODE and COPD stages, SGRQ and COPD stages and interrelation of BODE and SGRQ. RESULTS: We found significant differences in QoL of COPD patients and QoL in group of healthy volunteers (p <0.001). Lower QoL and higher BODE score were associated with a higher stages of COPD (p < 0.001), with the exception non-significant difference in QoL (SGRQ score) and BODE index between stages I and II. Our study found positive correlation between the all SGRQ scores and multidimensional prognostic BODE index (r = 0.431-0.704). The strongest correlation (r = 0.704) was evident in activity domain of SGRQ. CONCLUSION: Our results proved close correlation ofquality of life (SGRQ) and multidimensional prognostic score (BODE) in stable COPD exsmokers' population. Both these scoring systems are useful tools for the assessment of clinical course and stratification of severity of COPD. However at present both scales are minimally used in the Czech Republic.

RESUMO

INTRODUCTION: Borderline between upper and lower respiratory tract pathology is probably artificial (bronchial asthma). Also inflammation of bronchial mucosa during chronic obstructive pulmonary disease (COPD) is likely combined with inflammatory involvement of nasal mucosa. Ciliary edge of respiratory epithelium is very important part of mucosa layer. AIM: To investigate and compare nasal and bronchial ciliary beat frequency (CBF), degree of nasal and bronchial ciliary dyskinesia, presence of ciliary akinesia and incidence of spinocellular metaplasia in the both mucosa localities among of stable COPD patients (pts). METHOD: Nasal and bronchial mucosa were obtained in the course of bronchoscopy examination of COPD pts in general intravenous anesthesia. Native samples of mucosa tissue were assessed by digital high-speed video microscopy (1,000x magnification). Paired t-test was used to evaluate differences in average frequencies. Significance level was alpha = 0.05. Mode was used to describe "index of dyskinesia", as a measure of association was used K coefficient. MATERIAL: Seventeen COPD pts (6 weeks free of exacerbation) at the age 47-80 (average 64.2 years +/- 9.7) were examined (13 male), average FEV1 61% predic. value (21-81, +/- 15). All patients were active smokers (average 42 pack years +/- 22.8) and all suffered from bronchitic (daily sputum production) phenotype of COPD. RESULTS: We did not find any difference in average ciliary beat frequencies between nose (6.0 Hz +/- 1.3) and bronchus (5.9 +/- 1.3) locality (p = 0.427). We find weak association between nose and bronchus in "ciliary akinesia" (kappa = 0.282) but medium association in "metaplasia" (kappa = 0.485), in index of dyskinesia (kappa = 0.733). CONCLUSION: We did not find in our data any difference in nasal and bronchial ciliary beat frequencies and we found medium association between nasal and bronchial spinocellular metaplasia and index of ciliary dyskinesia. Possible generalization of these results would require further investigation and analysis.

RESUMO

OBJECTIVE: To assess the prevalence of antenatal depressive disorder in different trimesters and to evaluate the relation of psychosocial risk factors to antenatal depressive disorder. DESIGN: Cohort follow-up. SETTING: University Hospital, Kaunas, Lithuania. SAMPLE: Two hundred and thirty pregnant women consecutively admitted. METHODS: At 12-16 weeks, 22-26 weeks, and 32-36 weeks of pregnancy, participants were screened for depression using the World Health Organization's Composite International Diagnostic Interview Short Form (CIDI-SF). Women who gave at least one positive answer to the CIDI-SF depression-screening question were evaluated for depressive disorder using the non-patient version of the Structured Clinical Interview for DSM-III-R (SCID-NP). Psychosocial stressors and two Big Five Personality dimensions, neuroticism and extraversion, were also evaluated. MAIN OUTCOME MEASURES: Prevalence of depressive disorder. RESULTS: The prevalence of the antenatal depressive disorder at 12-16 weeks' gestation was 6.1%, at 22-26 weeks 3.5%, and at 32-36 weeks 4.4%. In the first trimester, a greater prevalence of current depressive disorder was independently associated with unplanned and unwanted pregnancy, high neuroticism, low education, and a previous history of depression; in the second trimester with unplanned and unwanted pregnancy and high neuroticism; in the third trimester with unplanned and unwanted pregnancy, high neuroticism, and the occurrence of psychosocial stressors during the last year. CONCLUSIONS: The highest prevalence of depressive disorders was found in the first trimester, the lowest in mid-pregnancy. Several determinants (unwanted and unplanned pregnancy, high neuroticism) were independent predictors of antenatal depressive disorders throughout whole pregnancy, while other determinants (low education, previous history of depression, the occurrence of psychosocial stressors at the end of pregnancy) were trimester specific.

RESUMO

UNLABELLED: Authors present an unusual eye finding in a 56 years old patient with Wegener's granulomatosis, who was followed up at the Department of Pulmonary Diseases, School of Medicine Hospital, Hradec Králové (Königgrätz), Czech Republic. From the point of view of the internal medicine, there are granulomas of the upper and lower airways and renal affection (minimally LK form). It consists of the affections of lungs and bronchi (histologically verified), kidneys (erytrocytouria with normal functions), eyes (ophthalmoscopically verified), weight loss about 10%, and possible nose involvement (suspect). The eye finding consists of severe anterior and posterior scleritis bilaterally, protrusion of the eyeball, and restricted movement of the left eye temporally with diplopia, and changing retinal findings bilaterally with the final improvement of consequently appearing foci of the serous retinal detachment. CONCLUSION: The paper demonstrates variety of ocular findings in Wegener's granulomatosis, and simultaneously emphasizes the importance of multidisciplinary collaboration in diagnosis and treatment of this serious disease.

RESUMO

BACKGROUND: The aim of the study was to find the factors predictive for paroxysmal atrial fibrillation (AF) following surgical correction of atrial septal defect type II (ASD t.II). METHODS: 93 patients, who underwent isolated surgical closure of ASD t.II between 1990 and 2001 were included. Follow-up studies were performed 2 - 11 years after surgery. Patients were divided into two groups according to the presence of AF before and after surgery. Group AF (+) consisted of 29 and group AF (-) of 64 patients. All patients underwent echocardiography, electrocardiogram (ECG) at rest, and signal-averaged P-wave duration (PWD) in signal-averaged ECG. The following parameters were assessed in echocardiography: pulmonary artery systolic pressure, left and right atrial dimensions, right ventricular dimension, tricuspid and mitral regurgitation. RESULTS: Paroxysmal AF was observed in 27 patients before surgery and in 29 after surgery. Analyzing all potential risk factors we proved that PWD may independently predict occurrence of postoperative AF. CONCLUSION: PWD may independently predict postoperative AF in long-term follow-up after surgical correction of ASD t.II.

RESUMO

AIMS: To investigate the prevalence, persistence and risk factors of high oncogenic risk human papillomavirus (HPV) among urban and rural women of reproductive age coming to consult a gynaecologist. METHODS: A prospective cohort study in urban (Kaunas) and rural (Marijampole) regions of Lithuania. The data were collected in 8 healthcare institutions from women seeking consultation of gynaecologists using a questionnaire for finding out demographic, social, behavioural and biomedical factors. HPV DNA was determined by molecular hybridization method (hybrid capture version II) determining HPV of high oncogenic risk. RESULT: 1,120 women participated in the study. The prevalence of high-risk HPV among the studied women was 25.1%. It was higher among the urban women than among the rural women. The prevalence of high-risk HPV was increased if the subjects had 2 or more sexual partners during the last 12 months (OR 2.81; 95% CI 1.83-4.32), were 19 years of age or younger (OR 2.68; 95% CI 1.47-4.91), were smoking (OR 1.81; 95% CI 1.16-2.81), and had secondary or lower education level (OR 1.43; 95% CI 1.01-2.04). This infection was obviously associated with high- and low-grade squamous intraepithelial changes of the cervix (OR 1.66, 95% CI = 1.08-2.53). CONCLUSION: The incidence rate for cervical cancer in Lithuania is one of the highest in comparison with other European countries. HPV infection was also particularly common in the studied population. About one-fourth of the women were infected with high-risk HPV infection. Young and less educated women were found to be the group that was most exposed to HPV, and therefore public health interventions and education seem to be essential in programs aimed at reducing the incidence of cervical cancer.

RESUMO

We propose new two and k-sample tests for evaluating the equality of survival distributions against alternatives that include crossing of survival functions, and proportional and monotone hazard ratios. The tests allow for right censored data. The asymptotic power against local alternatives is investigated. Simulation results demonstrate that the new tests are more powerful than known tests when survival functions cross. We apply the tests to a well known study of chemo- and radio-therapy conducted by the Gastrointestinal Tumor Study Group. The P-values for both proposed tests are much smaller than for other known tests.

RESUMO

BACKGROUND: T-wave alternans (TWA) at microvolt level is considered as an important non-invasive risk factor for sudden death. Several methods are used to measure such repolarization variations, but each of them has some limitations. The purpose of our study is to assess the usefulness of Poincaré maps, a method based on nonlinear dynamics theory, in detection of repolarization abnormalities. MATERIAL AND METHODS: In 30 postinfarction patients presence of TWA in precordial ECG leads was assessed by the spectral method (SM) and by the Poincaré maps (PM). Quantitative measures of both methods: alternans voltage (AV) and alternans distance (AD) were compared using linear regression. RESULTS: Significant correlation between both measures (r = 0.92, p < 0.01) was found. The value of AD > or = 10 microV was accepted as significant for the presence of T-wave alternans. CONCLUSIONS: Poincaré mapping seems to be a useful and simple method for detection of TWA. The alternans distance equal or greater than 10 microV can be considered as a level determinative for the presence of TWA.

RESUMO

UNLABELLED: The aim of the study was to evaluate cardiac function in patients with systemic sclerosis by means of noninvasive methods in order to detect early dysfunction of cardiovascular system. MATERIAL AND METHODS: We studied a group of 19 patients (15 women, 4 men, aged 17-74 yrs, av. 51 +/- 11) with systemic sclerosis comparing the results with a group of 23 healthy volunteers (17 women, 6 men aged 21-69 yrs, av 53 +/- 15). All the patients with SSc were taking corticosteroids, immunosuppressants or vasodilators at the time of the study. In all the patients we performed 24-hour Holter monitoring for the evaluation of arrhythmias, conduction disturbances, ischaemia, heart rate variability (HRV) and late potentials (LP). The following parameters of HRV in time domain were analyzed: SDNN, SDANN, SDNNI, rMSSD, pNN50. Standard ECG was performed to assess QT interval (QT, QTc, QTd). In all the patients the echocardiography examination was performed (M-Mode, 2-D, Doppler echocardiography). The morphology of heart structures and haemodynamic function were analyzed. RESULTS: In patients with SSc Holter monitoring revealed tendency to tachycardia. The mean heart rate was 81 +/- 11 vs. 71 +/- 9 in controls. Conduction disturbances were observed in 3 pts. In 6 pts we found significant ventricular arrhythmia. Silent ischaemia episodes were detected in 6 pts. Concerning HRV analysis the significantly lower values were detected in pts with SSc vs. controls: SDNN 123 vs 170; SDNNI 51 vs 76; SDANN 110 vs 152; rMSSD 29.6 vs 54; pNN50 6.1 vs 21. Late potentials were present in one patient with SSc vs none in the control group. The mean values QT-371, QTc-419, QTd-40- did not exceed the ranges of normal values. No signs of systolic cardiac dysfunction were detected, while in 6 pts we recognized left ventricle diastolic dysfunction. Valvular lesions were observed in 8 pts, but only in 2 pts they were hemodynamically important. CONCLUSIONS: 24-hour Holter monitoring and ECHO examination are valuable methods, which allow to detect early dysfunction of cardiovascular system in patients with systemic scleroderma presenting no apparent cardiac impairment symptoms.
