Characteristics and patient-reported outcomes of long-term lung cancer survivors.

Background: Due to advances in screening and treatment of lung cancer, there has been increased interest in long-term lung cancer survivors (LTLCS). The aim of this study was to evaluate the prevalence of LTLCS, their characteristics and patient-reported outcomes (PROs) of LTLCS. Methods: Cross-sectional study that included patients diagnosed with primary lung cancer between Jan 2012 and Dec 2016 whose overall survival (OS) was greater than 5 years. A self-administered questionnaire was applied, including European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30), Patient Health Questionnaire-4 (PHQ-4) and two open questions regarding quality of life (QoL) and suggestions for improvements. Factors potentially related to QoL were analysed. Results: Of 767 lung cancer patients, 158 (20.6%) were LTLCS and LTLCS' proportion increased yearly. Most patients were male (70.9%) with median age of 65 [interquartile range (IQR), 56-71] years. Fifty-seven percent had adenocarcinoma, 66.2% were diagnosed at early stages but 8.9% were at stage IV. During follow-up, 77.1% quitted smoking, 31.8% had disease progression/relapse and 15.2% developed other tumours. Of all living LTLCS, 100 (85%) patients answered the PROs questionnaire. The median Global Health score was 66.67 (IQR, 50-83), social functioning had the best score and emotional functioning the worst. Pain and fatigue were the symptoms with the worst impact on QoL. PHQ-4 identified mental distress in 36% and patients with a lower QoL were more likely to present anxiety (35.3% vs. 9.4%, P=0.007) or depression (27.9% vs. 3%, P=0.006). In the open questions, patients reported pain (17%), lack of familiar/financial support (16%), dyspnoea (14%), depression (8%), concern for the future (8%) and limitations performing daily activities (8%) as the aspects with most impact in QoL. The most suggested measures were improvement of care provided by health institutions (25%) and better social support (16%). Conclusions: Prevalence of LTLCS is increasing and survivors may experience a high prevalence of anxiety and depression as well as a high disease burden affecting QoL. Therefore, it's important to provide multidisciplinary continuous patient-centred care and a careful follow-up for all lung cancer patients, including LTLCS.

Stroke rehabilitation pathways during the first year: A cost-effectiveness analysis from a cohort of 460 individuals.

BACKGROUND: Stroke burden challenges global health, and social and economic policies. Although stroke recovery encompasses a wide range of care, including in-hospital, outpatient, and community-based rehabilitation, there are no published cost-effectiveness studies of integrated post-stroke pathways. OBJECTIVE: To determine the most cost-effective rehabilitation pathway during the first 12 months after a first-ever stroke. METHODS: A cohort of people in the acute phase of a first stroke was followed after hospital discharge; 51 % women, mean (SD) age 74.4 (12.9) years, mean National Institute of Health Stroke Scale score 11.7 (8.5) points, and mode modified Rankin Scale score 3 points. We developed a decision tree model of 9 sequences of rehabilitation care organised in 3 stages (3, 6 and 12 months) through a combination of public, semi-public and private entities, considering both the individual and healthcare service perspectives. Health outcomes were expressed as quality-adjusted life years (QALY) over a 1-year time horizon. Costs included healthcare, social care, and productivity losses. Sensitivity analyses were conducted on model input values. RESULTS: From the individual perspective, pathway 3 (Short-term Inpatient Unit ¼ Community Clinic) was the most cost-effective, followed by pathway 1 (Rehabilitation Centre ¼ Community Clinic). From the healthcare service perspective, pathway 3 was the most cost-effective followed by pathway 7 (Outpatient Hospital ¼ Private Clinic). All other pathways were considered strongly dominated and excluded from the analysis. The total 1-year mean cost ranged between €12104 and €23024 from the individual's perspective and between €10992 and €31319 from the healthcare service perspective. CONCLUSION: Assuming a willingness-to-pay threshold of one times the national gross domestic product (€20633/QALY), pathway 3 (Short-term Inpatient Unit ¼ Community Clinic) was the most cost-effective strategy from both the individual and healthcare service perspectives. Rehabilitation pathway data contribute to the development of a future integrated care system adapted to different stroke profiles.

Bilateral breast cancer and the influence of body mass index in clinicopathological features and overall survival.

BACKGROUND: Breast cancer (BC) and obesity are two closely associated pathologies with increasing incidence and mortality rates. Bilateral Breast Cancer (BBC) displays a low incidence rate within BC and obesity represents a major risk factor. OBJECTIVE: The aim of this study is to analyzed BBC clinicopathological features distribution and determine the potential influence of obesity in BBC in these same features and overall survival. METHODS: Clinicopathological information was obtained from 42 cases of women with BBC diagnosed in IPO-Porto. To evaluate the frequency distribution of the clinicopathological data, a chi-square goodness of fit test was performed for BBC cases. A chi-square test of independence was applied for BMI stratification. Cox regression was performed for overall survival. Statistical significance was set at p-value < 0.05. RESULTS: Distribution of BBC clinicopathological features was found to be statistically significant in family history (p-value < 0.001), BBC type (p-value < 0.001), stage (p-value = 0.005), differentiation grade (p-value < 0.001), receptor expression (p-value < 0.001) and histological type (p-value = 0.031). In comparison to the statistical expected results, we observed an increased cases of absence of family history and less cases of metachronous BBC. Histological types between tumours of BBC were mostly concordant. All cases presented concordant receptor expression. Analysis stratified by BMI revealed that obese women were diagnosed later, although without statistical significance. All obese women presented poor differentiation grade (n = 6). Overweight patients display a tendency to a better overall survival with lower tumour stages and lower differentiation grades. CONCLUSIONS: Our results reveal the same receptor expression between contralateral tumours. Also, most tumours share the same histological type. When stratified by BMI, we observed a tendency for overweight women to have improved overall survival.

Long-term neurological complications in COVID-19 survivors: study protocol of a prospective cohort study (NeurodegCoV-19).

BACKGROUND: Evidence suggests an association between SARS-CoV-2 infection and worse performance on cognitive tests, and a higher risk of Parkinson's disease (PD) and dementia up to 6 and 12 months after infection, respectively. Longer follow-ups with comparison groups are needed to clarify the potentially increased risk of neurodegenerative diseases in COVID-19 survivors, namely those infected before mass vaccination. METHODS: A prospective study started in July 2022 with four cohorts of 150 individuals each, defined according to SARS-CoV-2 infection and hospitalisation status between March 2020 and February 2021: cohort 1-hospitalised due to SARS-CoV-2 infection; cohort 2-hospitalised, COVID-19-free; cohort 3-infected, not hospitalised; cohort 4-not infected, not hospitalised. Cohort 2 will be matched to cohort 1 according to age, sex, level of hospitalisation care and length of stay; cohort 4 will be age-matched and sex-matched to cohort 3. Baseline, 1-year and 2-year follow-up evaluations will include: cognitive performance assessed with the Montreal Cognitive Assessment (MoCA) and neuropsychological tests; the assessment of prodromal markers of PD with Rapid Eye Movement Sleep Behaviour Disorder single-question Screen and self-reported olfactory and gustative alterations; screening of PD with the 9-item PD screening questionnaire; gait evaluation with Timed Up&Go test. Suspected cases of cognitive impairment and PD will undergo a clinical evaluation by a neurologist. Frequency measures of neurological complications, prodromal markers and diagnoses of dementia and PD, will be presented. The occurrence of cognitive decline-the difference between baseline and 1-year MoCA scores 1.5 SD below the mean of the distribution of the variation-will be compared between cohorts 1 and 2, and cohorts 3 and 4 with OR estimated using multivariate logistic regression. ETHICS AND DISSEMINATION: This study received ethics approval from the Ethics Committees of the health units Unidade Local de Saúde de Matosinhos and Centro Hospitalar de Entre Douro e Vouga, and informed consent is signed for participating. Results will be disseminated among the scientific community and the public.

Value of simple otoscopy in diagnosing otitis media with effusion in children

Aims To explore the value of otoscopy in diagnosing OME when performed by otorhinolaryngology, pediatrics, and primary care physicians; to evaluate the interobserver and intraobserver agreement of interpretation of otoscopy images. Material and methods A cross-sectional study using an anonymous mailed survey was used. We presented pre-recorded otoscopy images of pediatric patients to otorhinolaryngology, pediatrics, and primary care physicians (ten volunteer specialists and residents from each medical specialty). All participants had to answer “yes” or “no” if they considered that the image corresponded or not to an OME case, respectively. We considered that the images were positive for OME whenever the respective tympanogram was type B. Results Thirty-one otoscopy images and 1860 responses provided by sixty physicians were analyzed. The accuracy of otoscopy in diagnosing OME was highest in the Otolaryngologists group (mean 74.8%), with the worst rate observed in the primary care residents group (mean 51.3%). Overall sensitivity, specificity, and positive predictive value of otoscopy for diagnosing OME were significantly higher when performed by otorhinolaryngologists (75.8%, 72.8%, 66.8%, respectively). Fleiss' kappa showed that interobserver agreement was globally weak within each group of specialties, with overall better interobserver agreement observed among otorhinolaryngologists (κ = 0.30; 95% CI 0.27–0.32). Conclusion According to our data, simple otoscopy as a single diagnostic method in pediatric OME is insufficient, even for otorhinolaryngologists. Current recommendations must be followed to improve diagnostic accuracy. (AU)

From healthcare system to individuals through stroke rehabilitation pathways.Outcomes, information, and satisfaction along 12 months prospective cohort in Portugal.

BACKGROUND: The nature and quality of stroke survivor rehabilitation varies throughout Europe, including in Portugal, having not been widely monitored or benchmarked. OBJECTIVES: This study analyses the stroke care pathway from three perspectives: healthcare system, process, and patient. METHODS: The study uses data from a one-year single-center prospective cohort of first stroke patients, assessed at baseline, 3, 6, and 12 months. Care pathways and settings were described in terms of organizational model, funding, patient involvement, frequency and intensity and multidisciplinary team. Patient-level information and satisfaction were evaluated using a 10-point numeric rating scale. Kruskal - Wallis and post-hoc tests were used to compare EQ-5D-3 L, National Institute of Health Stroke Scale (NIHSS), Modified Rankin Scale (mRS), Barthel Index, Mini-Mental State Examination scores between pathways and settings. RESULTS: A total of 391 acute stroke patients, with a mean disability of 3.7 (mRS) and severity of 11.7 (NIHSS) participated. Six pathways and eight settings were described. A lack of compliance between guidelines and care was identified. There were significant differences in the four outcomes between the six pathways (p-values 0.007 to 0.020) suggesting inefficiency and inequalities, with an inadequate level of information and patient satisfaction. After post-hoc analysis, pathways 1 and 2 showed highest outcomes (p-values 0.001 to 0.002). Within settings, short-term units showed high scores, followed by rehabilitation center, outpatient hospital, and community clinic (p-values 0.001 to 0.040). CONCLUSION: A multilevel characterization of the post-stroke rehabilitation pathway showed a more complete perspective on stroke management which may contribute to future rehabilitation and stroke policies.

A Hybrid-Telerehabilitation Versus a Conventional Program for Urinary Incontinence: a Randomized Trial during COVID-19 Pandemic.

INTRODUCTION AND HYPOTHESIS: This study aimed to compare the effectiveness of a hybrid telerehabilitation program with a traditional face to face model in women with stress urinary incontinence (SUI) and mixed incontinence (MUI) with a predominance of SUI. The authors hypothesized that home pelvic floor muscle training (PFMT) would have a similar benefit to outpatient PFMT. METHODS: Parallel randomized controlled trial including 58 patients consecutively admitted to a tertiary academic hospital for pelvic floor rehabilitation consultation from 1 January to 30 April 2021 for conservative treatment of UI. Participants randomized to the intervention were submitted to a 12-week PFMT program: (1) a hybrid telerehabilitation program of two individual face-to-face sessions followed by 2-weekly sessions of video-telerehabilitation with a follow-up by a specialized physiotherapist, including one individual face-to-face session at 8 weeks; (2) a re-evaluation teleconsultation at 6 and 16 weeks; (3) a face-to-face consultation at 12 weeks. The control group had two initial individual sessions followed by twice-weekly group classes, and consultations were face to face. The primary outcome measure (at baseline and 12 weeks) was UI-related quality of life using the Portuguese Version of the King's Health Questionnaire. RESULTS: At baseline the intervention (n = 18) and control (n = 17) groups were similar. UI-related quality of life significantly improved in both the intervention and control groups betweenbaseline (T0) and the end of the 12-week PFMT program (T12) (p = 0.002, p < 0.001, respectively), although the magnitude of the improvement was not significantly different between groups (-10.0 vs. -9.5 points, p = 0.918, respectively). CONCLUSION: This hybrid telerehabilitation protocol showed effectiveness comparable to the traditional model in improving UI-related quality of life. Trial registration at www.

A retrospective study in tumour characteristics and clinical outcomes of overweight and obese women with breast cancer.

INTRODUCTION: Obesity and breast cancer are two major pathologies closely associated with increasing incidence and mortality rates, especially amongst women. The association between both diseases have been thoroughly discussed but much is still to uncover. AIM: The aim of this study is to analyse tumour characteristics and clinical outcomes of overweight and obese women to disclosure potential associations and better understand the impact of obesity in breast cancer. MATERIALS AND METHODS: Clinicopathological information of 2246 women were extracted from the institutional database of comprehensive cancer centre in Portugal diagnosed between 2012 and 2016. Women were stratified according to body mass index as normal, overweight, and obese. Patients' demographic information and tumour features (age, family history, topographic localization, laterality, histological type, and receptor status) were taken as independent variables and overall survival, tumour stage, differentiation grade and bilaterality were considered clinical outcomes. RESULTS: The main results reveal that overweight and obesity are predominantly associated with worse outcomes in breast cancer patients. Obese patients present larger (p-value: 0.002; OR 1.422; 95% CI 1.134-1.783) and more poorly differentiated tumours (p-value: 0.002; OR 1.480; 95% CI 1.154-1.898) and tend to have lower overall survival although without statistical significance (p-value: 0.117; OR 1.309; 95% CI 0.934-1.833). Overweighted women are more likely to have bilateral breast cancer (p-value: 0.017; OR 3.076; 95% CI 1.225-7.722) than obese women. The results also reveal that overweight women present less distant metastasis (p-value: 0.024; OR 0.525; 95%CI 0.299-0.920). Topographic localization and laterality did not achieve statistical significance.

COVID-19 collaborative screening: An action-research project for large scale contact tracing in Northern Portugal.

In late November 2020, when Europe reached the highest 14-day incidence of COVID-19 cases, the resource-intensive and time-consuming traditional contact tracing performed by Public Health was challenged. In this context, innovative approaches were necessary to guarantee a timely interruption of disease transmission. "COVID-19 Collaborative Screening" Project was developed as a faster solution, not only because the contact tracing process is simpler for the operator, but mainly because it is possible to quickly scale up the number of operators involved. It was designed to interrupt family and social transmission chains, in a partnership with the Local Public Health Services - allowing these services to dedicate to scenarios of more complex risk assessment, using the traditional contact tracing. To perform contact tracing, this method involves Public Servants, Armed Forces and Medical Dentists. The Project also promotes participatory citizenship, by delegating to the citizen the responsibility of registering his/hers contacts with high-risk exposure in an online form, in contrast to the traditional contact tracing method which is more health professional-dependent. Until the end of January 2021, the Project has trained eight teams, enrolling a total of 213 professionals, and was implemented in eight Health Regions (with an estimated population of 1,346,150 inhabitants). The Project was successful at facing the delays in case interview and contact tracing. The strategy implemented by ColabCOVID is assembled as a sustainable, reproducible and scalable platform and is ready to be re-implemented to face the emergence of more contagious variants, as well as an eventual forthcoming health threat.

The disruption of elective procedures due to COVID-19 in Brazil in 2020.

Elective procedures were temporarily suspended several times over the course of the pandemic of COVID-19. Monthly data from the Unified Health System (SUS) were used for the period between January 2008 and December 2020 and the interrupted time series method was used to estimate the effect of the pandemic on the number of elective surgeries and elective procedures that were not performed. Considering a 9-month period, a reduction of 46% in the number of elective procedures carried out in the SUS could be attributed to COVID-19, corresponding to about 828,429 elective procedures cancelled, ranging from 549,921 to 1,106,936. To a full recovery of pre-pandemic performance, SUS would need to increase about 21,362 hospital beds, ranging from 12,370 to 36,392 hospital beds during a 6 month-period. This effort would represent an increase of 8.48% (ranging from 4.91 to 14.45%) in relation to the total number of SUS's hospital beds in 2019. As a result, the pandemic will leave a large number of elective procedures to be carried out, which will require efforts by health agencies to meet this demand.

Finding Predictors of Azathioprine-Induced Pancreatitis in Patients With Inflammatory Bowel Disease.

OBJECTIVES: Azathioprine (AZA)-induced pancreatitis (AIP) is a common, idiosyncratic adverse effect whose incidence and risk factors data in inflammatory bowel disease (IBD) patients are not fully clarified. We aimed to establish the incidence, clinical course and identify risk factors for AIP. METHODS: A retrospective study including all IBD patients on AZA between January 2013 and July 2020 was conducted. Patients with AIP were considered. RESULTS: Azathioprine-induced pancreatitis occurred in 33 patients (7.5%; 442 patients on AZA). The mean time receiving AZA until AIP was 25 days, with a mean dose of 88 mg. All patients had a mild course of disease, which resolved with suspension of AZA and with no complications. Smoking (P = 0.02), single daily dose of AZA (P < 0.001), and concomitant budesonide (P = 0.001) were risk factors for AIP. In multivariate analysis, concomitant treatment with budesonide (odds ratio, 5.3; P = 0.002) and single daily dose of AZA (odds ratio, 3.8; P = 0.002) were the only predictors of AIP. CONCLUSIONS: Although AIP was a relatively common adverse effect, it presented a mild course in all patients. Smoking, concomitant use of budesonide, and single-dose regimen of AZA should be avoided in IBD patients treated with AZA.

What attributes do patients prefer in a family physician? A cross-sectional study in a northern region of Portugal.

OBJECTIVES: To determine which modifiable and non-modifiable attributes patients prefer in a family physician, as well as to analyse participants' characteristics associated with their choices. DESIGN: Cross-sectional study. SETTING: Family healthcare units (FHU) in the city of Braga and Barcelos (Northern Portugal). PARTICIPANTS: Adults aged 18 years or more, enrolled in the selected FHU. MAIN OUTCOME MEASURES: The preferred attributes were assessed with a questionnaire delivered in the FHU. These attributes included gender, age and nationality and the importance of being Portuguese, of greeting with a handshake, of welcoming in the waiting area, of using an identification badge and of wearing a white coat. RESULTS: A total of 556 questionnaires were included in the analysis; 66% and 58% of the participants had no preference for the gender or age of the family physician, respectively. Using a multinomial logistic regression, male participants were 3.8 times more likely to have a preference for a male physician than having no preference, in comparison to female participants (OR 3.864, 95% CI 1.96 to 7.61). More than 69% of the participants considered greeting with a handshake, using an identification badge and wearing a white coat important or very important. There was a statistically significant association between being Portuguese and the major importance given to the use of an identification badge (ß=0.68, 95% CI 0.23 to 1.12). CONCLUSIONS: Our data show that modifiable attributes of the family physician (greeting, presence of an identification badge and wearing a white coat) are important for patients. Potential changes in family physician attitude in consultation could ultimately affect patient-physician relationship.

Survival Impact and Cost-Effectiveness of a Multidisciplinary Tumor Board for Breast Cancer in Mozambique, Sub-Saharan Africa.

BACKGROUND: Despite the international endorsement of multidisciplinary tumor boards (MTBs) for breast cancer care, implementation is suboptimal worldwide, and evidence regarding their effectiveness in developing countries is lacking. We assessed the impact on survival and the cost-effectiveness of implementing an MTB in Mozambique, sub-Saharan Africa. MATERIALS AND METHODS: This prospective cohort study included 205 patients with breast cancer diagnosed between January 2015 and August 2017 (98 before and 107 after MTB implementation), followed to November 2019. Pre- and post-MTB implementation subcohorts were compared for clinical characteristics, treatments, and overall survival. We used hazard ratios and 95% confidence intervals (CI), computed by Cox proportional hazards regression. The impact of MTB implementation on the cost per quality-adjusted life year (QALY) was estimated from the provider perspective. RESULTS: We found no significant differences between pre- and post-MTB subcohorts regarding clinical characteristics or treatments received. Among patients with early breast cancer (stage 0-III; n = 163), the 3-year overall survival was 48.0% (95% CI, 35.9-59.1) in the pre-MTB and 73.0% (95% CI, 61.3-81.6) in the post-MTB subcohort; adjusted hazard ratio, 0.47 (95% CI, 0.27-0.81). The absolute 3-year mean cost increase was $119.83 per patient, and the incremental cost-effectiveness ratio was $802.96 per QALY, corresponding to 1.6 times the gross domestic product of Mozambique. CONCLUSION: The implementation of a MTB in Mozambique led to a 53% mortality decrease among patients with early breast cancer, and it was cost-effective. These findings highlight the feasibility of implementing this strategy and the need for scaling-up MTBs in developing countries, as a way to improve patient outcomes. IMPLICATIONS FOR PRACTICE: Currently, more than half of the deaths from breast cancer in the world occur in developing countries. Strategies that optimize care and that are adjusted for available resources are needed to improve the outcomes of patients with breast cancer in these regions. The discussion of cases at multidisciplinary tumor boards (MTBs) may improve survival outcomes, but implementation is suboptimal worldwide, and evidence regarding their effectiveness in developing countries is lacking. This study evaluated the impact of implementing an MTB on the care and survival of patients with breast cancer in Mozambique, sub-Saharan Africa and its cost-effectiveness in this low-income setting.

Cost-effectiveness of a stepwise intervention to promote adherence to cervical cancer screening.

BACKGROUND: Cervical cancer screening is effective in reducing mortality, but adherence is generally low. We aimed to investigate the cost-effectiveness of a stepwise intervention to promote adherence to cervical cancer screening in Portugal. METHODS: We developed a decision tree model to compare the cost-effectiveness of four competing interventions to increase adherence to cervical cancer screening: (i) a written letter (standard-of-care); (ii) automated short message service text messages (SMS)/phone calls/reminders; (iii) automated SMS/phone calls/reminders + manual phone calls; (iv) automated SMS/phone calls/reminders + manual phone calls + face-to-face interviews. The main outcome measure was cost per quality-adjusted life year (QALY) measured over a 5-year time horizon. Costs were calculated from the societal and provider perspectives. RESULTS: From the societal perspective, the optimal strategy was automated SMS/phone calls/reminders, below a threshold of €8171 per QALY; above this and below €180 878 per QALY, the most cost-effective strategy was automated SMS/phone calls/reminders + manual phone calls and above this value automated SMS/phone calls/reminders + manual phone calls + face-to-face interviews. From the provider perspective, the ranking of the three strategies in terms of cost-effectiveness was the same, for thresholds of €2756 and €175 463 per QALY, respectively. CONCLUSIONS: Assuming a willingness-to-pay threshold of one time the national gross domestic product (€22 398/QALY), automated SMS/phone calls/reminders + manual phone calls is a cost-effective strategy to promote adherence to cervical cancer screening, both from the societal and provider perspectives.

Hemodynamic differences among hypertensive patients with and without heart failure using impedance cardiography.

BACKGROUND: Impedance cardiography is a reliable, well-tolerated, and non-invasive method used to obtain hemodynamic measurements and could potentially be useful in heart failure (HF) diagnosis, hemodynamic monitoring of critically ill patients, and help in the choice of antihypertensive therapy. The objective of this study was to determine the differences between hemodynamic parameters in a study population of hypertensive patients with and without HF, using impedance cardiography. METHODS: A case-control study was designed and named the TARGET study. Participants were enrolled in two study groups: control group C, hypertensive patients without HF and the HF group, hypertensive patients with HF. A descriptive analysis was carried out to characterize the sample and differences in continuous variables were tested for statistical significance by independent sample t test. RESULTS: The study included 102 hypertensive outpatients. The control group consisted of 77 individuals (58.4% males; mean age 63.9 ± 12.5 years old) and the HF group consisted of 25 individuals (44.0% males; mean age 74.2 ± 8.7 years old). The mean Cardiac Index (CI) was 2.70 ± 1.02 L.min.m-2 (2.89 ± 1.04 versus 2.12 ± 0.70; p < 0.001), mean Stroke Index (SI) was 35.5 ± 14.7 mL.m-2 (37.7 ± 15.2 versus 28.5 ± 10.8; p = 0.006), mean Ejection Phase Contractility Index (EPCI) was 33.7 ± 12.7 1000 s-2 (35.8 ± 13.1 versus 27.2 ± 9.2; p = 0.003), mean Inotropic State Index (ISI) was 74.3 ± 28.2 100 s-2 (78.8 ± 28.9 versus 60.6 ± 20.7; p = 0.005), and mean Left Stroke Work Index (LSWI) was 51.3 ± 23.1 g.min.m-2 (55.4 ± 23.5 versus 38.9 ± 16.6; p = 0.002). CONCLUSIONS: In this study, hypertensive patients with HF had significantly lower values of blood flow parameters, contractility, and left work indices compared with hypertensive patients without HF. These differences reflected the incorrect hemodynamic pattern (mostly hypodynamic) of these patients. Impedance cardiography (ICG) seems to be an adequate method to reflect these differences.

The effects on the acoustic parameters and auditory-perceptive characteristics of voice in children submitted to adenoidectomy with or without tonsillectomy.

OBJECTIVES: To analyse the possible changes on the acoustic parameters and auditory-perceptive characteristics of children's voice after adenoidectomy with or without tonsillectomy. METHODS: Prospective cohort study of children aged 5-12 years at one month before surgery (t0) and one (t1), three (t3) and six (t6) months after adenoidectomy with or without tonsillectomy. On each assessment the acoustic parameters (fundamental frequency, jitter %, shimmer % and harmonics-to-noise ratio) and auditory-perceptive analysis (nasal resonance, loudness, pitch, GRBAS scale and maximum phonation time) were recorded. RESULTS: A total of 51 children were considered for data analysis. Nasal resonance revealed a significant decrease in the number of cases with hyponasality, from 86.3% at t0 to 12.8% at t1 (p < 0.001), 2.3% at t3 (p < 0.001) and 2.8% at t6 (p < 0.001). This improvement was maintained during the late follow-up time with no significant difference on nasal resonance between t0 and t3 (p = 0.250) and t3 and t6 (p = 0.250). All children with alteration on the GRBAS scale before the procedure showed a normal voice quality after the surgery. Regarding the acoustic parameters none showed a significant change with the surgery. CONCLUSIONS: The results suggest that adenoidectomy with or without tonsillectomy is a safe procedure concerning voice alterations and can improve voice quality and nasal resonance in a sustained manner.

A 3-step intervention to improve adherence to cervical cancer screening: The SCAN randomized controlled trial.

The aim of this study was to test the effectiveness of a stepwise intervention with an increasing level of complexity and cost to increase adherence to organized cervical cancer screening. This was a randomized (1: 1) controlled trial, conducted among 13 Portuguese primary health care units. Participants (n = 1220) were women aged 25-49 years, eligible for cervical cancer screening, with a mobile phone number available. The tested intervention was a 3-step invitation to screening, based on automated text messages/phone calls (step 1), manual phone calls (step 2) and face-to-face interviews (step 3), applied sequentially to non-adherent women after each step. Participants in the control group were invited through a written letter (standard of care). The primary outcome was the proportion of women screened, which was assessed after step 1 (45 days after the initial invitation), steps 1 + 2 (90 days after the initial invitation) and steps 1 + 2 + 3 (150 days after the initial invitation). Adherence to cervical cancer screening was significantly higher among women assigned to the intervention than those in the control group for step 1 (39.9% vs. 25.7%, p < 0.001), steps 1 + 2 (48.6% vs. 30.7%, p < 0.001) and steps 1 + 2 + 3 (51.2% vs. 34.0%, p < 0.001). In conclusion, adherence to cervical cancer screening was higher by 17% among women invited through the 3-step intervention, compared to those receiving the standard invitation letter. The former strategy has the potential to be broadly implemented due to the low requirements of technology and training. Clinical Trial Registration: NCT03122275.
