Effects of a stigma reduction intervention on help-seeking behaviors in university students: A 2019-2021 randomized controlled trial.

INTRODUCTION: Stigma is one of the most frequently identified help-seeking barriers, but there is a lack of research on the effects of stigma reduction interventions on actual mental health help-seeking behaviors during crucial academic years. This research explores the effects of stigma on university students' mental health care help-seeking behaviors before and during the pandemic. METHODS: A randomized control trial spanned from 2019 to 2021 at the University of Porto, along five evaluation moments, with students into one control group and two intervention groups-the interventions aimed to reduce depression stigma. RESULTS: Among the 702 participants (mean age 18.87, 59.4 % female), the intervention groups significantly increased help-seeking behaviors. In 2020, the intervention groups, having reduced stigma, continued to demonstrate to be more prompt to seek mental health help. In 2021, 22 months, the effects of the intervention on help-seeking were no longer significant; however, participants in the intervention groups showed less severe symptomatology. CONCLUSION: Stigma reduction interventions have a pronounced effect on enhancing help-seeking behaviors among university students, even during times of crisis. This study advocates for prioritizing stigma reduction in academic settings, highlighting its value in promoting mental health access during crucial academic and life challenges.

Long COVID Symptoms in Non-Hospitalised Patients: A Retrospective Study.

INTRODUCTION: The COVID-19 pandemic has presented numerous challenges to healthcare systems. As the number of affected individuals continues to rise, it is crucial to find preventive, diagnostic, and therapeutic approaches. This study aims to describe different COVID-19 sequelae within a Primary Health Care population. METHODS: A retrospective cohort study was conducted in adults diagnosed with COVID-19 from March 2020 to April 2022, excluding pregnant women, minors, nursing home residents, hospitalizations, and deaths. Data was gathered from surveillance records on the Trace COVID-19® platform, a pre-set original questionnaire (which included the Portuguese version of the World Health Organization's Quality of Life Assessment Instrument), and, if needed, patient electronic health records. Information on sociodemographic and clinical characteristics of acute COVID-19 was collected along with long COVID symptoms. RESULTS: This study included 284 patients, aged 19 to 99 years old. The five most prevalent acute COVID-19 symptoms were fever (50.0%), tiredness (48.2%), myalgias (44.7%), dry cough (37.7%) and odynophagia (36.3%). Symptoms related to the neurological system (23.2%) and tiredness (22.9%) were the most prevalent in long COVID symptoms. Acute tiredness and arthralgia were associated with all long COVID outcomes. The associations between acute COVID-19 symptoms with long COVID outcomes were stronger for anosmia [OR = 5.07, 95% confidence interval (CI) 2.49 - 10.36, p < 0.001] on a neurological chapter, acute tiredness for long lasting tiredness (OR = 4.07, 95% CI 2.07 - 8.02, p = 0.041), fatigue for muscles and/or bones chapter (OR = 7.55, 95% CI 3.06 - 18.66, p < 0.001), tiredness on an endocrine/hormonal chapter (OR = 6.54, 95% CI 2.37 - 18.04, p < 0.001), dyspnea for respiratory symptoms (OR = 5.67, 95% CI 1.92 - 16.74, p = 0.002) and fever for stomach or intestine symptoms (OR = 8.06, 95% CI 2.55 - 25.47, p < 0.001). Almost all quality of life dimensions were negatively associated with the number of long COVID symptoms. CONCLUSION: A higher number of acute symptoms, as well as the presence of specific COVID-19 symptoms were associated with reported symptoms ≥ 12 weeks after infection. In the studied population, an increased number of symptoms in both acute and long COVID had a significant negative impact on the perception of overall quality of life. The identification of these relationships could provide a new perspective for post-COVID care.

AnsT-19: Development and Validation of a Scale to Access the Anxiety of Family Physicians during Teleconsultation.

INTRODUCTION: Following the outbreak of the disease caused by the novel coronavirus it was necessary to increase the non-face-to-face care activity through alternative means such as teleconsultation in primary health care. The adjustment to a type of remote consultation could have generated anxiety among family physicians. The main aim of the present study was to develop and validate a scale to assess the anxiety of family physicians during teleconsultation. MATERIAL AND METHODS: Observational, cross-sectional study involving a sample of family physicians working in Portugal. An online survey that evaluated anxiety in teleconsultation was developed. RESULTS: A total of 359 valid responses were included in an exploratory factor analysis, after determining the number of factors to retain. A four-factor structure was detected with loadings ranging overall, from 0.44 to 0.98. Correlations between factors ranged from 0.42 to 0.58. Exploratory factor analysis results varied between good and very good fit, with chi-square/df result = 2.448, root mean square error of approximation (RMSEA) = 0.062 [90% CI = (0.053, 0.073)], root mean square of the residuals (RMSR) = 0.030 and Tucker Lewis index (TLI) = 0.931. Composite reliability was higher than 0.7 for all factors and average variance extracted was close or above 0.5 for the extracted factors, confirming convergent validity. McDonald's omega (ω) = 0.95 suggested the presence of a second-order factor, and thus a global measure for assessing anxiety during teleconsultation. Concurrent validity results were good, with correlations ranging from r = -0.277 to r = -0.393 with General Self-Efficacy scale (GSE) and r = 0.302 to r = 0.547 with Depression Anxiety Stress scales (DASS). Moderate correlations found between DASS and the dimensions of AnsT-19 suggest that AnsT-19 is capturing anxiety from the teleconsultation point of view. AnsT-19 factors and total score were significantly associated with gender, experience as a family doctor, psychotropic medication during the pandemic period and pre-pandemic experience of teleconsultation, indicating good construct validity. The limitations of the study are related to the convenience process, the use of an online survey and self-reported measurements. CONCLUSION: AnsT-19 is a valid instrument to assess the anxiety of family physicians during teleconsultation.

Frailty in Portuguese Older Patients From Convalescence Units: A Cross-Sectional Study.

Background: Frailty is a common geriatric syndrome, associated with adverse clinical outcomes. Nevertheless, studies about frailty in continuous care units are scarce. In this way, this study aimed to assess frailty in older patients admitted in convalescence units (CUs) and analyze its association with demographic, social and clinical characteristics. Methods: This cross-sectional study included older patients admitted in eight CUs of the Integrated Continued Care National Network in Northern Portugal. Exclusion criteria were: total ≤ 11 in Glasgow coma scale, < 10 in mini-mental state examination or being unable to communicate. A comprehensive protocol was administered to assess health-related and lifestyle characteristics, comorbidity, dependence on activities of daily living (ADL), depressive and anxiety symptoms, cognition, and socio-familial risk. Frailty was assessed by Tilburg frailty indicator (TFI). Results: A sample of 165 patients was included (median age = 77; 65% female), with 80% classified as frail, mostly women (P = 0.002), widowed (P = 0.016), shorter (P = 0.005), feeling more tired (P < 0.005) and with less energy (P < 0.005). Also, these patients reported more vision problems (P = 0.006), difficulties in walking (P = 0.022) and climbing stairs (P = 0.029), pain (P = 0.004), falls (P = 0.046), non-alcohol use (P = 0.043) and non-physical activity (P = 0.032). Frail patients had a higher number of previous hospitalizations (P = 0.018), comorbidity (P = 0.006), dependence on instrumental (P < 0.001) and basic (P = 0.006; P < 0.001) ADL, depressive (P < 0.001) and anxiety (P = 0.002) symptoms. After adjusting for covariates, frailty was associated with females (adjusted odds ratio (aOR) = 4.45, P = 0.011), vascular disease (aOR = 4.40, P = 0.040), vision problems (aOR = 10.85, P < 0.001), high dependency on instrumental ADL (aOR = 0.74, P = 0.002), and depressive symptoms (aOR = 1.37, P = 0.001). Conclusions: Frailty is high among older patients in CUs, particularly in females, with vascular disease, vision problems, instrumental ADL dependence and depressive symptoms. Thus, frailty should be screened, and preventive and therapeutic measures should be considered for those at high risk, in order to minimize possible negative consequences.

Suicide time-series structural change analysis in Portugal (1913-2018): Impact of register bias on suicide trends.

BACKGROUND: Suicide is a potentially preventable cause of death. Epidemiology might help to identify death determinants and to monitor prevention strategies. Few studies address secular trends in suicide deaths, and even fewer describe trend-changes in relation to data collection/registration bias. Moreover, suicide is admittedly underreported. It is crucial to validate results in the context of other external causes of death trends, such as unintentional and undetermined intent deaths. We aimed to explore trends in suicide and other external causes of death in Portugal from the inception of registries until 2018, considering breaks in series. METHODS: We collected data from all available official primary sources. We calculated cause-specific age-standardized death rates (SDR) by sex for ages equal or higher than 15 years with reference to the European Standard Population. We considered suicide (S), undetermined intent deaths (UnD), accidents (Accs), and all causes of death (ttMty). A time-series structural analysis was executed. RESULTS: Suicide and other external causes of death rates were consistently higher in males than females. A global decline of deaths by suicide, undetermined intention and unintentional is observable. Breakpoints in years 1930, 1954, 1982, 2000-2001 were associated with major changes in deaths registration procedures or methodology. CONCLUSIONS: The epidemiology of suicide in Portugal has changed over 106 years. However, adjusted data and consideration of bias reduce trends fluctuation. Trend changes are akin to specific changes in methodology of death registry. Suicide surveillance will improve with more reliable and stable procedures.

European Portuguese Version of the Clinical Frailty Scale: Translation, Cultural Adaptation and Validation Study.

INTRODUCTION: This study aims to describe the translation and adaptation of the European Portuguese Clinical Frailty Scale and assess its convergent validity and test-retest reliability. MATERIAL AND METHODS: This validation study included a sample of elderly people admitted in two convalescence units from the National Network of Integrated Continuous Care in Northern Portugal and followed in two outpatient clinics of social solidarity institutions. Convergent validity of the scale was evaluated, against Tilburg Frailty Indicator. Test-retest reliability, sensitivity and specificity were assessed. RESULTS: Overall, 51 patients were included (mean age = 78 years old). The Clinical Frailty Scale identified 43.1% patients with frailty. Kappa values for test-retest reliability (non-frail/frail) was 1.00. The intraclass correlation coefficient for the 9-point total scale was 0.999. A correlation between Clinical Frailty Scale and Tilburg Frailty Indicator was also found (rs = 0.683; p < 0.001). The Cohen's kappa coefficient was 0.423 in the agreement analysis between these scales. The results for sensitivity and specificity defined that 62.0% of patients were true positives and 81.8% true negatives. The scale accuracy determined by the receiver operating characteristics curve analysis was 0.782. DISCUSSION: This scale showed an excellent test-retest reliability. Robust results on convergent validity were also achieved, with a moderate correlation and agreement with the Tilburg Frailty Indicator, showing good sensitivity and accuracy, as well as high specificity. CONCLUSION: This version has an excellent test-retest reliability and good convergent validity, and is both a reliable and valid test for application in clinical practice for assessing Portuguese elderly population admitted in convalescence units and outpatient clinics.

Psychometry and Pescatori projective test in coloproctological patients.

BACKGROUND: Psychological assessment is not commonly performed nor easily accepted by coloproctological patients. Our aim was to evaluate the psychological component of coloproctological disorders using uncommon tools. METHODS: The 21-Item Depression Anxiety and Stress Scale and the Pescatori projective test were applied to coloproctological outpatients of the Gastroenterology Department of our hospital as well as to healthy volunteers. RESULTS: Seventy patients (median age 47 years, 22 male) divided in 4 groups (functional constipation, constipated irritable bowel syndrome, benign anorectal disease and perianal Crohn's disease) and 52 healthy volunteers (age 45 years, 18 male) completed the tests. Proctological patients showed higher scores of depression (P<0.001), anxiety (P<0.001), and stress (P<0.001) compared to healthy participants. Compared to the control group, patients with functional constipation, irritable bowel syndrome and perianal Crohn's disease maintained the highest scores in all subscales (P<0.05), while patients with benign anorectal disease only had higher anxiety and stress (P<0.001) scores. The patients' also showed lower scores in the Pescatori projective test (P=0.012). A weak association between the projective test and the depression subscale was found (P=0.05). CONCLUSION: Proctological patients had higher scores of depression, anxiety and stress and lower scores in the Pescatori projective test compared to healthy controls.

Risk factors for mortality in end-stage kidney disease patients under online-hemodiafiltration: three-year follow-up study.

The aim of this work was to evaluate the predictors of mortality in a group of end-stage kidney disease (ESRD) patients under dialysis, by performing a three-year follow-up study. From the 236 patients included in this study, 54 patients died during the three-year follow-up period. Our data showed that the risk of death was higher in patients presenting lower levels of mean cell hemoglobin concentration, transferrin, and albumin. Our study showed that poor nutritional status and an inflammatory-induced iron depleted erythropoiesis are important factors for mortality in these patients.

Brain functional connectivity patterns for emotional state classification in Parkinson's disease patients without dementia.

Successful emotional communication is crucial for social interactions and social relationships. Parkinson's Disease (PD) patients have shown deficits in emotional recognition abilities although the research findings are inconclusive. This paper presents an investigation of six emotions (happiness, sadness, fear, anger, surprise, and disgust) of twenty non-demented (Mini-Mental State Examination score >24) PD patients and twenty Healthy Controls (HCs) using Electroencephalogram (EEG)-based Brain Functional Connectivity (BFC) patterns. The functional connectivity index feature in EEG signals is computed using three different methods: Correlation (COR), Coherence (COH), and Phase Synchronization Index (PSI). Further, a new functional connectivity index feature is proposed using bispectral analysis. The experimental results indicate that the BFC change is significantly different among emotional states of PD patients compared with HC. Also, the emotional connectivity pattern classified using Support Vector Machine (SVM) classifier yielded the highest accuracy for the new bispectral functional connectivity index. The PD patients showed emotional impairments as demonstrated by a poor classification performance. This finding suggests that decrease in the functional connectivity indices during emotional stimulation in PD, indicating functional disconnections between cortical areas.

First Incidence and Progression Study for Diabetic Retinopathy in Portugal, the RETINODIAB Study: Evaluation of the Screening Program for Lisbon Region.

PURPOSE: To estimate the 5-year incidence and progression of diabetic retinopathy (DR) among persons with type 2 diabetes mellitus (DM). DESIGN: Population-based, prospective, cohort study. PARTICIPANTS: The RETINODIAB (Study Group for Diabetic Retinopathy Screening) program was implemented in the Lisbon and Tagus Valley area between July 2009 and December 2014. A total of 109 543 readable screening examinations were performed and corresponded to 56 903 patients who attended the screening program at entry. A total of 30 641 patients (53.85%) had at least 1 further screening event within the study period and were included in the analysis. METHODS: Participants underwent two 45° nonstereoscopic retinal digital photographs per eye according to RETINODIAB protocol. All images were graded according to the International Clinical Diabetic Retinopathy Scale. Referable diabetic retinopathy (RDR) was defined for all patients graded as moderate nonproliferative DR (NPDR), severe NPDR, or proliferative DR (PDR), with or without maculopathy or mild NPDR with maculopathy. Nonparametric estimates of the annual and cumulative incidences were obtained by Turnbull's estimator. Associations between the potential risk factors and the time to onset/progression of retinopathy were assessed through a parametric survival analysis for interval-censored data. MAIN OUTCOME MEASURES: The authors estimated the onset and progression incidence rates of DR. RESULTS: Yearly incidence of any DR in patients without retinopathy at baseline was 4.60% (95% confidence interval [CI], 3.96-4.76) in the first year, decreasing to 3.87% (95% CI, 2.57-5.78) in the fifth year. In participants with mild NPDR at baseline, the progression rate to RDR in year 1 was 1.18% (95% CI, 0.96-1.33). Incidence of any DR and RDR and DR progression rate were associated with known duration of diabetes, age at diagnosis, and use of insulin treatment. CONCLUSIONS: This longitudinal epidemiologic study provides the first Portuguese incidence DR data in a large-scale population-based cohort of type 2 diabetes after a 5-year follow-up. Duration of diabetes, age at diagnosis, and insulin treatment were associated with increasing risk of incidence and progression of DR. A personalized schedule distribution of screening intervals according to the individual patient's profile should be implemented, with resulting benefits in terms of health costs.

First diabetic retinopathy prevalence study in Portugal: RETINODIAB Study--evaluation of the screening programme for Lisbon and Tagus Valley region.

BACKGROUND/AIMS: In Portugal, so far, there is no study or even accurate data on the prevalence of diabetic retinopathy (DR), based on a large representative sample and on a long-term follow-up. The objective of our study was to determine the prevalence of DR based on a national screening community-based programme. METHODS: A 5-year retrospective analysis of the RETINODIAB screening programme results was implemented in Lisbon and Tagus Valley area between July 2009 and October 2014. We estimated the prevalence of retinopathy for all patients with type 2 diabetes and studied the association between known risk factors and retinopathy emergence at their first screening. RESULTS: Throughout this period, from a total of 103 102 DR readable screening examinations, 52 739 corresponded to patients who attended RETINODIAB screening at entry. Globally, DR was detected in 8584 patients (16.3%). Of these, 5484 patients (10.4%) had mild non-proliferative (NP) DR, 1457 patients (2.8%) had moderate NPDR and 672 (1.3%) had severe NPDR. Finally, 971 patients (1.8%) had proliferative DR requiring urgent referral to an ophthalmologist. The presence of any DR, non-referable DR or referable DR was strongly associated with increasing duration of diabetes and earlier age at diagnosis. CONCLUSIONS: The prevalence rate of DR in our study (16.3%) was slightly lower than other published international data. The RETINODIAB network proved to be an effective screening programme as it improved DR screening in Lisbon and Tagus Valley surrounding area.

Predictors of health-related quality of life perceived by end-stage renal disease patients under online hemodiafiltration.

PURPOSE: Patients' perception of health-related quality of life (HRQOL) is a consistent and powerful predictor of the outcome of end-stage renal disease (ESRD) patients under dialysis. This study aims to identify factors that could affect the HRQOL of ESRD patients under online hemodiafiltration (OL-HDF). METHODS: We evaluated 322 ESRD patients under OL-HDF (59.63% males; 64.9 ± 14.3 years old) from five dialysis units in the north of Portugal. Socio-demographic data, comorbidities, hematological data, iron status, dialysis adequacy, nutritional and inflammatory markers were collected from patients records. Patient's reported HRQOL score was assessed by using the Kidney Disease Quality of Life-Short Form (KDQOL-SF). RESULTS: ESRD patients showed a mean (± SD) of 53.17% (± 15.31%) in SF-36 total score, 50.17% (± 9.51%) in the SF-36 mental component summary (MCS) and 49.75% (± 9.44%) in the SF-36 physical component summary (PCS). Red cell distribution width (RDW), feminine gender and diabetes were found as significant predictors of SF-36 total score of HRQOL, which accounts for 12% of the total explained variance. Patient satisfaction, RDW, body mass index and gender were identified as predictors for the PCS, which accounts for 22% of total explained variance. Furthermore, patient satisfaction and dry weight were found as predictors for MCS. These predictors accounted for 28% of the total explained variance. CONCLUSIONS: Our results showed that the coexistence of diabetes, gender and erythropoietic disturbances are predictors of HRQOL in patients under OL-HDF and suggest that more attention should be given to woman patients, to the improvement of anemia and to diabetic patients, who are more prone to perceive a worst HRQOL.

Mucositis care in acute leukemia and non-Hodgkin lymphoma patients undergoing high-dose chemotherapy.

PURPOSE: This study intends to provide new insights into the incidence and care of mucositis by the epidemiological characterization of patients with hematological malignancy treated at our institution. It also aims to understand the effectiveness of several treatments used. METHODS: This is a longitudinal observational single-center study-convenience sample-which includes malignant hematologic inpatients submitted to high-dose CT from February to August 2012. We registered epidemiological data, diagnosis, oral mucositis daily questionnaire (OMDQ), World Health Organization (WHO) oral toxicity scale, and supportive medications used for mucositis. RESULTS: We evaluated 30 patients who had 73 episodes of hospitalization, having recorded the development of mucositis in 21.9 % (n = 16) episodes (22 patients with acute leukemia (AL) and 8 patients with non-Hodgkin lymphoma (NHL)). Grades 3-4 mucositis was reported in 4.1 % of the total episodes. The results of OMDQ showed some limitations in the quality of life, of patients with mucositis, related with the ability to eat and drink due to mouth pain (p < 0.001). In patients with NHL and AL, neutropenia entails an increased risk of mucositis (p < 0.001). Patients who did not initiate early prophylaxis with conservative measures developed mucositis earlier (p < 0.05). CONCLUSIONS: The incidence of mucositis is high, being reported mainly in AL patients, with limitations in quality of life. Grade 4 neutropenia increases mucositis risk. Early prophylaxis with basic oral care may delay mucositis. Further studies are crucial to characterize mucositis epidemiology, physiopathology, and its management.

On the analysis of EEG power, frequency and asymmetry in Parkinson's disease during emotion processing.

OBJECTIVE: While Parkinson's disease (PD) has traditionally been described as a movement disorder, there is growing evidence of disruption in emotion information processing associated with the disease. The aim of this study was to investigate whether there are specific electroencephalographic (EEG) characteristics that discriminate PD patients and normal controls during emotion information processing. METHOD: EEG recordings from 14 scalp sites were collected from 20 PD patients and 30 age-matched normal controls. Multimodal (audio-visual) stimuli were presented to evoke specific targeted emotional states such as happiness, sadness, fear, anger, surprise and disgust. Absolute and relative power, frequency and asymmetry measures derived from spectrally analyzed EEGs were subjected to repeated ANOVA measures for group comparisons as well as to discriminate function analysis to examine their utility as classification indices. In addition, subjective ratings were obtained for the used emotional stimuli. RESULTS: Behaviorally, PD patients showed no impairments in emotion recognition as measured by subjective ratings. Compared with normal controls, PD patients evidenced smaller overall relative delta, theta, alpha and beta power, and at bilateral anterior regions smaller absolute theta, alpha, and beta power and higher mean total spectrum frequency across different emotional states. Inter-hemispheric theta, alpha, and beta power asymmetry index differences were noted, with controls exhibiting greater right than left hemisphere activation. Whereas intra-hemispheric alpha power asymmetry reduction was exhibited in patients bilaterally at all regions. Discriminant analysis correctly classified 95.0% of the patients and controls during emotional stimuli. CONCLUSION: These distributed spectral powers in different frequency bands might provide meaningful information about emotional processing in PD patients.
