Factors associated with poor health literacy in older adults: A systematic review.

OBJECTIVES: To identify factors associated with poor health literacy in older adults. METHODS: A systematic literature review was conducted, employing the descriptors "Aged" and "Health Literacy". PROSPERO - CRD: 42022350140. RESULTS: Out of 23,500 articles screened, 176 were selected. Several factors associated with poor health literacy in older adults were identified, such as sociodemographic (e.g., advanced age, low educational level, non-white population, and others), social (e.g., poor family/social support, loneliness, social isolation, few social activities, and others), economic (e.g., lower income and/or lower socioeconomic status) and health aspects (e.g., poor health, chronic conditions, mental health challenges, hospitalizations, frailty, physical inactivity, cognitive impairment, and others). CONCLUSIONS: The factors associated with poor health literacy in older adults identified in this review could contribute to future research, support interventions to improve health literacy, and assist professionals in planning educational activities and public policies.

Factors Associated with Symptoms of Posttraumatic Stress in Mothers During the COVID-19 Pandemic.

OBJECTIVES: The objective of the study was to evaluate the factors associated with symptoms of posttraumatic stress in mothers during the COVID-19 pandemic. METHODS: Cross-sectional study conducted with mothers of children and adolescents living in Brazil, who answered an online questionnaire containing sociodemographic variables and the Impact of Events Scale-Revised. The Poisson regression model with robust variance was used to identify the factors associated with posttraumatic stress. RESULTS: A percentage of 83.82% of mothers reported an overload in caring for their children during the pandemic. The prevalence of posttraumatic stress symptoms was 39.05%, and this condition was associated with younger age, living in the northern region of the country, using medications, presenting neuropsychiatric comorbidities and being little/more or less satisfied with life. CONCLUSIONS FOR PRACTICE: The mental health situation of mothers during and after the pandemic must be monitored, in order to guarantee public policies capable of optimizing the coping with the situation.

Symptoms of depression, anxiety and stress in Brazilian mothers during the COVID-19 pandemic.

The study aimed to identify the factors associated with symptoms of depression, anxiety and stress in Brazilian mothers of children and adolescents during the COVID-19 pandemic. This is a cross-sectional study carried in 2020 with the participation of 822 mothers who answered an online questionnaire containing sociodemographic variables and the Depression, Anxiety and Stress Scale (DASS-21). The adjusted model showed a higher depression score in women who became unemployed during the pandemic, who felt a greater burden in taking care of children, who took medication on a regular basis, and who self-assessed their health as regular or poor/very poor. Having a lower family income increased their anxiety scale score. In contrast, the variables associated with a reduced anxiety scale score included greater age, not feeling overwhelmed with demands to care for children, not using medications, not having gastrointestinal diseases, and good/very good self-assessed health. These variables, together with the benefits of living in the Northeast and Midwest regions of Brazil as well as sleeping more hours per night, were also associated with reduced stress. The present study is significant as it points out elements present in the daily lives of mothers that have an impact on their mental health. The study points to the need to (re)think mental health policies taking into account the needs of the public studied.

Factors Associated With Influenza Vaccination During the COVID-19 Pandemic in Older Adults Residing in Brazil.

The current study aimed to assess influenza vaccination coverage and explore factors related to vaccine uptake in older adults in 2020 amid the coronavirus disease 2019 pandemic. A cross-sectional study using an online questionnaire was performed with 380 older adults (aged ≥60 years), living in Brazil, from May 26 to June 29, 2020. Data regarding sociodemographic, health, and social support variables were collected. Data were analyzed using Poisson regression with robust variance. Influenza vaccination coverage in the sample was 85.5% (95% confidence interval [81.6, 88.7]). Older adults with increased age had higher vaccination coverage, whereas those who were smokers, not wearing masks, and sometimes and never/almost never received professional support had lower vaccination rates. Data show that vaccine coverage for influenza in 2020 was below that recommended by Brazilian authorities. We reinforce the importance of information about the influenza vaccine, especially for younger older adults, smokers, and those who do not wear masks. Reliable information from health care professionals and the media is essential for vaccination during a pandemic. [Journal of Gerontological Nursing, 49(5), 31-38.].

Factors associated with depressive and anxiety symptoms in older adults during the COVID-19 pandemic: a Brazilian study.

Objectives: Older adults are one of the most vulnerable age groups to the social distance measures imposed by the COVID-19 pandemic. This study aimed to assess factors associated with depressive and anxiety symptoms in Brazilian older adults during the pandemic.Method: This cross-sectional online study assessed 380 older adults (over 60 years of age) living in Brazil, from 26th May 2020 to 29th June 2020. A self-reported questionnaire included sociodemographic data, lifestyle, health characteristics, and the COVID-19 related variables. The Geriatric Depression Scale (GDS) and the Geriatric Anxiety Inventory (GAI) were also applied. Data were analyzed via logistic regression models, using a hierarchical approach.Results: The prevalence of depressive symptoms according to GDS was 28.7% (95% CI = 24.4%, 33.4%) and the prevalence of anxiety symptoms according to GAI was 26.1% (95% CI = 21.9%, 30.7%). Physically inactive older adults, the ones who were in social isolation for more days, feel much vulnerable to contracting COVID-19, and never or almost never receive support from family/friends were more likely to have depressive symptoms. Being female, physically inactive or physically active 1-3 times/week, feel very vulnerable to contracting COVID-19 and never or almost never receive support from family/friends were associated with the anxiety symptoms.Conclusion: A high prevalence of depressive and anxious symptoms was identified in Brazilian older adults. The data can help in planning interventions aimed at older adults, also including their families, health professionals, and the whole society.

Interobserver agreement of PI-RADS v. 2 lexicon among radiologists with different levels of experience.

BACKGROUND: Evaluation of interobserver agreement of the PI-RADS v2 lexicon is important to validate the uniformity of this widely used classification. PURPOSE: To determine the interobserver agreement of PI-RADS v2 lexicon among eight radiologists with varying levels of experience. STUDY TYPE: Retrospective. POPULATION: In all, 160 consecutively imaged men with confirmatory targeted biopsy. FIELD STRENGTH/SEQUENCE: 3T scanner without an endorectal coil. T2 -weighted imaging (T2 w), diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC) map and dynamic contrast-enhanced sequence were performed. ASSESSMENT: Eight radiologists (two highly experienced, two moderately experienced, and four less experienced) independently read 130 lesions in the peripheral zone (PZ) and 30 lesions in the transition zone (TZ), blinded to clinical MRI indication and biopsy results. The features described in PI-RADS v2 for TZ and PZ lesions were evaluated. STATISTICAL TESTS: Conger's kappa, percentage of concordance, and first-order agreement coefficient (AC1) were used to evaluate interobserver agreement. RESULTS: From the features evaluated on PZ lesions, definite extraprostatic extension (EPE) / invasive behavior on T2 w had good agreement (AC1 = 0.80), and the others had fair agreement (AC1 = 0.32-0.40). From the features evaluated on TZ lesions, two had good agreement: definite EPE/invasive behavior (AC1 = 0.77) and moderate/marked hypointensity (AC1 = 0.67) on T2 w. Encapsulation and lenticular shape on T2 w, focal (not indistinct) on DWI and ADC map, and marked hypointensity on ADC map (AC1 = 0.45 to 0.60) had moderate agreement, whereas heterogeneous and circumscribed (not obscured margins) on T2 w, marked hyperintensity on high-b-value DWI, and the presence or not of early enhancement in the lesion/region of the lesion (AC1 = 0.30 to 0.38) had fair agreement. DATA CONCLUSION: Interobserver agreement in PI-RADS v2 lexicon ranges from fair to good among radiologists and improves with increasing experience. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2020;51:593-602.

Objective value on Apparent diffusion coefficient (ADC) map to categorize the intensity of diffusion-weighted imaging (DWI) restriction for prostate cancer detection on multiparametric prostate MRI.

PURPOSE: To identify objective and subjective criteria on multiparametric prostate MRI that can be helpful for prostate cancer detection. MATERIALS AND METHODS: Retrospective study, IRB approved, including 122 patients who had suspicious lesion on MRI and who underwent prostate biopsy with ultrasonography (US)/MRI imaging fusion. There were 60 patients with positive biopsies and 62 with negative biopsies. MRI of these patients were randomized and evaluated independently by two blinded radiologists. The following variables were analyzed in each lesion: morphology, contours, T2 signal, diffusion restriction (subjective impression and objective values), hyper-enhancement, contact with transition zone or prostatic contour, prostatic contour retraction, Likert and PIRADS classification. RESULTS: Apparent diffusion coefficient (ADC) value was the best predictor of positivity for prostate cancer, with mean value of 1.08 (SD 0.20) and 1.09 mm2/sec (SD 0.24) on negative biopsies and 0.81 (SD 0.22) and 0.84 mm2/sec (SD 0.22) on positive biopsies for readers 1 and 2, respectively (p < 0.001 in both analysis). For the others categorical variables evaluated the best AUC for reader 1 was subjective intensity of diffusion restriction (AUC of 0.74) and for reader 2 was hyper-enhancement (AUC of 0.65), all inferior comparing to the value of ADC map. Interobserver agreement ranged from 0.13 to 0.75, poor in most measurements, and good or excellent (kappa > 0.6) only in lesion size and ADC values. CONCLUSIONS: Diffusion restriction with lower ADC-values is the best parameter to predict cancer on MRI prior to biopsy. Efforts to establish an ADC cutoff value would improve cancer detection, especially for less experience reader.

Comparison between multiparametric MRI with and without post - contrast sequences for clinically significant prostate cancer detection.

BACKGROUND: Dynamic-contrast enhanced (DCE) sequence is used to increase detection of small lesions, based on increased vascularization. However, literature is controversy about the real incremental value of DCE in detection of clinically significant (CS) prostate cancer (PCa), since absence of enhancement does not exclude cancer, and enhancement alone is not definitive for tumor. PURPOSE: To test the hypothesis that DCE images do not increase CS PCa detection on MRI prior to biopsy, comparing exams without and with contrast sequences. Material and Materials and Methods: All men who come to our institution to perform MRI on a 3T scanner without a prior diagnosis of CS PCa were invited to participate in this study. Reference standard was transrectal prostate US with systematic biopsy and MRI/US fusion biopsy of suspicious areas. Radiologists read the MRI images prospectively and independently (first only sequences without contrast, and subsequently the entire exam) and graded them on 5-points scale of cancer suspicion. RESULTS: 102 patients were included. Overall detection on biopsy showed CS cancer in 43 patients (42.2%), clinically non-significant cancer in 11 (10.8%) and negative results in 48 patients (47%). Positivities for CS PCa ranged from 8.9% to 9.8% for low suspicion and 75.0% to 88.9% for very high suspicion. There was no statistical difference regarding detection of CS PCa (no statistical difference was found when compared accuracies, sensitivities, specificities, PPV and NPV in both types of exams). Inter-reader agreement was 0.59. CONCLUSION: Exams with and without contrast-enhanced sequences were similar for detection of CS PCa on MRI.

Berberine-induced cardioprotection and Sirt3 modulation in doxorubicin-treated H9c2 cardiomyoblasts.

Doxorubicin (DOX) is one of the most widely used anti-neoplastic agents. However, treatment with DOX is associated with cumulative cardiotoxicity inducing progressive cardiomyocyte death. Sirtuin 3 (Sirt3), a mitochondrial deacetylase, regulates the activity of proteins involved in apoptosis, autophagy and metabolism. Our hypothesis is that pharmacological modulation by berberine (BER) pre-conditioning of Sirt3 protein levels decreases DOX-induced cardiotoxicity. Our results showed that DOX induces cell death in all experimental groups. Increase in Sirt3 content by transfection-mediated overexpression decreased DOX cytotoxicity, mostly by maintaining mitochondrial network integrity and reducing oxidative stress. p53 was upregulated by DOX, and appeared to be a direct target of Sirt3, suggesting that Sirt3-mediated protection against cell death could be related to this protein. BER pre-treatment increased Sirt3 and Sirt1 protein levels in the presence of DOX and inhibited DOX-induced caspase 9 and 3-like activation. Moreover, BER modulated autophagy in DOX-treated H9c2 cardiomyoblasts. Interestingly, mitochondrial biogenesis markers were upregulated in in BER/DOX-treated cells. Sirt3 over-expression contributes to decrease DOX cytotoxicity on H9c2 cardiomyoblasts, while BER can be used as a modulator of Sirtuin function and cell quality control pathways to decrease DOX toxicity.

Mitochondrial apoptosis-inducing factor is involved in doxorubicin-induced toxicity on H9c2 cardiomyoblasts.

The cardiotoxicity induced by the anti-cancer doxorubicin involves increased oxidative stress, disruption of calcium homeostasis and activation of cardiomyocyte death. Nevertheless, antioxidants and caspase inhibitors often show little efficacy in preventing cell death. We hypothesize that a caspase-independent cell death mechanism with the release of the apoptosis-inducing factor from mitochondria is involved in doxorubicin toxicity. To test the hypothesis, H9c2 cardiomyoblasts were used as model for cardiac cells. Our results demonstrate that z-VAD-fmk, a pan-caspase inhibitor, does not prevent doxorubicin toxicity in this cell line. Doxorubicin treatment results in AIF translocation to the nuclei, as confirmed by Western Blotting of cell fractions and confocal microscopy. Also, doxorubicin treatment of H9c2 cardiomyoblasts resulted in the appearance of 50kbp DNA fragments, a hallmark of apoptosis-inducing factor nuclear effects. Apoptosis-inducing factor knockdown using a small-interfering RNA approach in H9c2 cells resulted in a reduction of doxorubicin toxicity, including decreased p53 activation and poly-ADP-ribose-polymerase cleavage. Among the proteases that could be responsible for apoptosis-inducing factor cleavage, doxorubicin decreased calpain activity but increased cathepsin B activation, with inhibition of the latter partly decreasing doxorubicin toxicity. Altogether, the results support that apoptosis-inducing factor release is involved in doxorubicin-induced H9c2 cell death, which explains the limited ability of caspase inhibitors to prevent toxicity.

Monitoring risk factors for dementia in middle-aged and older adults: a longitudinal study.

Given the importance of dementia syndrome and its impacts on the population, interest in studying modifiable risk factors for dementia is growing. Objective: To compare the prevalence of risk factors for dementia in middle-aged and older adults over a two-year period and to identify what variables in baseline were predictive of cognitive decline in the follow-up. Methods: Longitudinal and quantitative study, with follow-up evaluation after two years, conducted with 200 participants aged 45 years or more, registered in Primary Care Units. In the baseline (2018/2019) and follow-up (2021) assessments, sociodemographic data were collected, and cognitive performance and risk factors for dementia were evaluated (education, hearing loss, head trauma, high blood pressure, alcohol use, obesity, smoking, depressive symptoms, social isolation, physical inactivity, and diabetes mellitus). Data were compared using the McNemar's test. Individual multinomial logistic regression models were performed to identify the factors associated with cognitive decline after two years. Results: The percentages of low education, traumatic brain injury, and smoking remained the same in both assessments. There was a significant increase in the prevalence of high blood pressure (from 55.0 to 62.0%) and physical inactivity (from 58.5 to 74.5%) and a significant reduction in social isolation (from 25.0 to 18.0%). Participants with depressive symptoms in baseline had a higher risk of cognitive decline in follow-up. Conclusion: There was an increase in the prevalence of high blood pressure and physical inactivity and a reduction in social isolation after two years. Depressive symptoms predict cognitive decline.

Dada a importância da síndrome demencial e de seus impactos na população, cresce o interesse em estudar os fatores de risco modificáveis para a demência. Objetivo: Comparar a prevalência de fatores de risco para demência em adultos de meia-idade e pessoas idosas, em um período de dois anos, e identificar quais fatores de risco na avaliação de base predizem o declínio cognitivo na avaliação de acompanhamento. Métodos: Estudo longitudinal e quantitativo, com avaliação de acompanhamento após dois anos, realizado com 200 participantes com 45 anos ou mais, cadastrados na Atenção Básica. Nas avaliações de base (2018/2019) e de acompanhamento (2021) foram coletados dados sociodemográficos, foram feitas avaliação cognitiva e avaliação dos fatores de risco para demência (escolaridade, perda auditiva, traumatismo craniano, hipertensão arterial, uso de álcool, obesidade, tabagismo, sintomas depressivos, isolamento social, inatividade física, diabetes mellitus). Os dados foram comparados pelo teste de McNemar. Modelos de regressão logística multinominal individuais foram conduzidos para identificar quais fatores estavam associados ao declínio cognitivo após dois anos. Resultados: Os percentuais de baixa escolaridade, traumatismo craniano e tabagismo mantiveram-se os mesmos nas duas avaliações. Houve aumento significativo da prevalência de hipertensão arterial (de 55,0 para 62,0%) e inatividade física (de 58,5 para 74,5%), e redução significativa do isolamento social (de 25,5 para 18,0%). Participantes com sintomas depressivos na avaliação de base apresentaram maior risco de declínio cognitivo no acompanhamento. Conclusão: Houve aumento das prevalências de hipertensão arterial e inatividade física; e redução do isolamento social. Sintomas depressivos predizem declínio cognitivo.

Relationship between depressive symptoms, social isolation, visual complaints and hearing loss in middle-aged and older adults.

The prevalence of chronic diseases, especially depression, has been increasing worldwide. Health professionals have an important role in screening and early detection of the disorder, to prevent possible damage such as disability and dependence. With aging, sensory impairments can occur, such as visual and hearing losses, which can lead to isolation contributing to the development of depressive symptoms. The objective of this study was to analyze the relationship between depressive symptoms, social isolation, and self-perception of visual complaints and hearing loss in middle-aged and older adults. It was a cross-sectional quantitative study, in Três Lagoas, state of Mato Grosso do Sul, Brazil, with 300 participants of both sexes, aged 45 years and over, registered in the Primary Health Care network. Data were collected using a structured questionnaire with sociodemographic data and the questions "Do you consider yourself socially isolated?", "Do you have a vision and/or a hearing problem capable of stopping you from performing a daily life activity?" and "If yes, do you use a hearing aid and/or glasses or contact lenses?". Depressive symptoms were assessed using the Center for Epidemiological Studies - Depression (CES-D) scale with a cut-off score adapted for age. Data were analyzed with binary logistic regression, with the presence of depressive symptoms being the dependent variable. Values of p≤0.05 were considered significant. The majority of the sample were women (65.7%), with an average age of 60.9 years, 56.7% were classified with depressive symptoms, 27.0% considered themselves socially isolated, 84.7% reported visual acuity loss (70.7% used glasses) and 17.3% reported hearing loss (2.3% used hearing aids). Social isolation (OR = 6.0), visual complaints (OR = 3.85), and hearing loss (OR = 4.67) were related to the presence of depressive symptoms. Moreover, being married (OR = 0.51) was a protective factor in these participants. The results showed the importance of early diagnosis of depressive symptoms. The correction of visual and hearing deficits is highlighted, as these may be related to symptoms of depression. Health professionals in Primary Health Care should be able to monitor depressive symptoms, visual and hearing complaints, and to promote social interaction.

IgE-mediated cow's milk allergy in Brazilian children: Outcomes of oral food challenge.

Background: Oral food challenge (OFC) is useful for diagnosing food allergies and assessing tolerance, but severe reactions may occur during the procedure. Objective: To characterize the frequency and severity of reactions during cow's milk (CM) OFCs. Methods: A cross-sectional study was conducted to analyze the outcome of cow's milk oral food challenges (CMOFCs) performed to confirm IgE-mediated CM allergy or to assess food tolerance. CM was given first as baked milk (BM), followed by whole CM if there was no prior reaction to BM. An OFC was considered positive if IgE-mediated symptoms developed up to 2 h after ingestion. Symptoms were described and variables including age at OFC, prior anaphylaxis, other atopic diseases, and skin test results were compared according to the OFC outcomes. Results: A total of 266 CMOFCs were performed, including 159 patients with a median age of 6.3 years old. One hundred thirty-six tests were positive and 62 resulted in anaphylaxis. Thirty-nine anaphylactic reactions were observed up to 30 min after the first dose. Severe anaphylaxis (cardiovascular and/or neurological involvement) was reported in 5 tests. A second dose of epinephrine was required in 3 tests, and 1 presented a biphasic response. Younger patients had a higher risk of anaphylaxis during baked milk oral food challenge (BMOFC) (p = 0.009). The frequency of anaphylaxis was higher in patients submitted to BM (p = 0.009). Conclusions: Anaphylaxis is a known complication of CMOFCs even when there is no prior anaphylaxis or when conducted with baked products. This study reinforces the importance of conducting OFC in appropriate settings with a well-trained team.

Agreement between fragility assessment instruments for older adults registered in primary health care.

OBJECTIVE: To assess the level of agreement between the Subjective Frailty Assessment (SFA) and Clinical Functional Vulnerability Index (CFVI-20) for the diagnosis of frailty in older adults. METHODS: A descriptive, comparative, cross-sectional study was conducted in 2018/2019 with 492 older adults at nine Family Health Strategy units in the city of Três Lagoas, state of Mato Grosso do Sul, Brazil. Frailty was assessed using the SFA and CFVI-20 in addition to a structured interview. The Wilcoxon test and Pearson's chi-squared test were used for the comparisons. RESULTS: Agreement was 35.4%, with a Kappa coefficient of 0.11. After dichotomizing the sample into frail and non-frail individuals, agreement was 70.1%, with a Kappa coefficient of 0.41 and Cronbach's alpha coefficients of 0.61 and 0.74 for IVCF-20 and SFA, respectively. The prevalence of frailty was lower using the IVCF-20 (17.1%) compared to 59.8% using the SFA. CONCLUSION: Agreement regarding the classification of frailty between the two instruments ranged from low to moderate. This finding underscores the need for a standardized instrument for measuring frailty in community-dwelling older adults.

[Epidemiology of hepatitis C virus infection]. / Epidemiologia da infecção pelo vírus da hepatite C.

Hepatitis C is a major cause of chronic liver disease worldwide. There is a significant variation in the prevalence of hepatitis C virus (HCV) infection according to the geographic region studied. These discrepancies reflect not only distinct epidemiological characteristics among the populations, but also differences in the methodologies used for the estimates. Despite scarce data, estimates indicate that Brazil is a country with an intermediate prevalence of HCV infection, ranging from 1% to 2%. The most important risk factors for HCV acquisition include injection drug use, blood product transfusion, organ transplantation, hemodialysis, occupational injury, sexual transmission and vertical transmission. Because there is no vaccine and no post-exposure prophylaxis for HCV, the focus of primary prevention efforts should be identification and removal of the risk factors. In this article we review literature regarding the prevalence of HCV infection, particularly in Brazil. In addition, we discuss the pattern of HCV infection according to the age groups and risk factors for HCV acquisition.

Information Disclosed in Patent Documents being the Source to Address Emergencies: A Strategy to Achieve Technological Developments Addressing COVID-19.

BACKGROUND: Face COVID-19 pandemic, a need for accurate information on SARS-CoV-2 virus is urgent and scientific reports have been published on a daily basis to enable effective technologies to fight the disease progression. However, at the initial occurrence of Pandemic, no information on the matter was known and technologies to fight the Pandemic were not readily available. However, searches in patent databases, if strategically designed, can offer quick responses to new pandemics. OBJECTIVE: The objective of this study is aiming to provide existing information in patent documents useful for the developmentof technologies addressing COVID-19. Considering the emergency situation the world was facing and the knowledge of COVID-19 available until April, 2020, this work presents an analysis of the main characteristics of the technological information in patent documents worldwide, related to coronaviruses and the severe acute respiratory syndrome (SARS). METHODS: Regions of concentration of such technologies, the number of available documents and their technological fields are disclosed in three approaches: 1) a wide search, retrieving technologies on SARS or coronaviruses; 2) a targeted search, retrieving documents additionally referring to Angiotensin converting enzyme (ACE2), which is used by SARS- CoV-2 to enter a cell and 3) a punctual search, which retrieved patents disclosing aspects related to SARS- CoV-2 available at that time. RESULTS: Results show the high-level technology involved in these developments and a monopoly tendency of such technologies, also evidencing that it is possible to find answers to new problems in patent documents. CONCLUSION: This work, then, aims to contribute to scientific and technological development by raising the awareness of what should be considered when searching for technologies developed for other matters that could provide solutions for a new problem.

Which criteria can be used to predict benignity in solid renal lesions lower-equal to 2 cm?

PURPOSE: To evaluate magnetic resonance imaging (MRI) criteria of solid renal lesions lower-equal to 2 cm to differentiate benign and malignant tumors, using histopathology as gold standard. METHODS: Three radiologists independently evaluated objective and subjective MRI criteria of focal renal lesions. A total of 105 nodules of patients who had MRI and histopathological results in our institution were included. Subjective criteria evaluated were signal on T2-weighted imaging, presence of microscopic and macroscopic fat, hemosiderin, hemorrhage, central scar, segmented inversion enhancement and enhancement type; objective criteria were gender, ADC value, heterogeneity on T2-weighted imaging and proportion of enhancement in late post-contrast phases. Finally, the readers classified the lesions in probably benign or malignant. Interobserver agreement was evaluated by the Gwet method, and the quantitative variables by intraclass correlation coefficients. To adjust the predictive model, the logistic regression model was used considering the benignity variable as outcome. RESULTS: A total of 26 nodules (24.5%) were benign and 79 (75.2%) were malignant, with size ranging from 7 to 20 mm (median: 14 mm). The most frequent subtype was papillary renal cell carcinoma (RCC) (35.2%), followed by clear-cell RCC (24.8%) and oncocytoma (12.4%). The univariate and multivariate analysis showed, among all categories evaluated, that microscopic fat (p: 0.072), intermediate (p: 0.004) and hyper-enhancement (p: 0.031) and female sex (p: 0.0047) had the best outcome for benignity, within odds ratios of 4.29, 5.75, 4.07 and 2.86, respectively. CONCLUSION: In small solid renal lesions lower-equal to 2 cm, microscopic fat, moderate and hyper-enhancement and female sex were associated with benignity.

Prevalence of risk factors for dementia in middle- and older- aged people registered in Primary Health Care.

It is important to assess the prevalence of risk factors for dementia to slow down the progression and evolution of the disease, and to support interventions and prevention programs. OBJECTIVE: We aimed to evaluate the prevalence of these factors in individuals registered in Primary Health Care in Brazil and their relationship with sex and age group. METHODS: This was a cross-sectional and quantitative study with n=300 individuals. We evaluated the prevalence of main risk factors (low education, hearing loss, high blood pressure, obesity, smoking, depression, physical inactivity, social isolation, and diabetes mellitus) and others (poor diet, alcohol use, head trauma, monolingualism, visual impairment, and sleep disorders) identified in the literature. Poisson regression was used, according to sex and age group (45-59 years/60+ years). RESULTS: The main risk factors with the highest prevalence were physical inactivity (60.3%) and depressive symptoms and hypertension (56.7% each). Among the other factors, monolingualism (98.0%), visual impairment (84.7%), and irregular consumption of fruits (60.4%), and vegetables (53.5%) prevailed. No differences were identified between sexes. The regression analysis confirmed a significant difference for education and age group, with older individuals having a higher prevalence of low schooling. CONCLUSION: The results can guide interventions, especially in developing countries. Practice of physical activity and healthy eating should be the focus of these interventions as they can indirectly help in reducing the prevalence of other factors. Early identification, screening and adequate treatment of depressive symptoms, high blood pressure and visual impairment can also contribute to reducing the prevalence of dementia.

A identificação da prevalência de fatores de risco para demência é importante para reduzir a velocidade da progressão e evolução da doença, e para subsidiar programas de prevenção e intervenção. OBJETIVO: O objetivo foi avaliar a prevalência desses fatores em indivíduos cadastrados na Atenção Primária à Saúde (APS), relacionando com sexo e faixa etária. MÉTODOS: Estudo transversal e quantitativo, com n=300 indivíduos acima de 45 anos. Avaliou-se a prevalência dos fatores de risco principais para demência (baixa escolaridade, perda auditiva, hipertensão arterial, obesidade, tabagismo, depressão, inatividade física, isolamento social e diabetes mellitus) e dos outros fatores (má alimentação, consumo de álcool, traumatismo craniano, unilinguismo, déficit visual e distúrbios do sono), identificados na literatura. Conduziu-se uma regressão de Poisson, por sexo e faixa etária (45-59 e 60+ anos). RESULTADOS: Os fatores de risco principais com maior prevalência foram a inatividade física (60,3%), a sintomatologia depressiva e a hipertensão arterial (56,7% cada). Dentre os outros fatores, prevaleceram: unilinguismo (98,0%), déficit visual (84,7%), consumo irregular de frutas (60,4%) e de verduras ou legumes (53,5%). Não foram identificadas diferenças entre os sexos. Confirmou-se diferença significativa para a escolaridade e faixa etária, com os idosos apresentando maior prevalência de baixa escolaridade. CONCLUSÃO: Os resultados podem guiar intervenções, especialmente em países em desenvolvimento. A prática de atividades físicas e a alimentação devem ser o foco dessas intervenções, auxiliando indiretamente na redução da prevalência de outros fatores. A identificação precoce, o rastreamento e o tratamento adequado de sintomas depressivos, hipertensão arterial e déficit visual também são importantes.

Prostate volume measurement by multiparametric magnetic resonance and transrectal ultrasound: comparison with surgical specimen weight.

OBJECTIVE: To assess accuracy of multiparametric magnetic resonance of the prostate to estimate gland volume, comparing the results with transrectal ultrasound and surgical specimen. METHODS: A retrospective study of 85 patients who underwent multiparametric magnetic resonance and transrectal ultrasound (for fusion image-guided biopsy) before radical prostatectomy. Prostate measurements were obtained from magnetic resonance axial and sagittal T2-weighted images and ultrasound; the prostate volume was determined using the ellipsoid formula. The results were compared with the surgical specimen weight. Maximum interval between multiparametric magnetic resonance imaging, transrectal ultrasound, and prostatectomy was 6 months. RESULTS: The prostate volume measured by multiparametric magnetic resonance imaging was 18-157cm3 (mean of 49.9cm3) and by transrectal ultrasound, 22-165cm3 (mean of 54.9cm3); the surgical specimen weight was 20-154g (mean of 48.6g), with no statistical differences. Based on the values obtained from imaging examinations, the prostate volume obtained was very close to the real prostatic weight, and the measures by multiparametric magnetic resonance were slightly more precise. CONCLUSION: Prostate volume measured by multiparametric magnetic resonance imaging and transrectal ultrasound showed similar values, and excellent agreement with real prostate weight of the surgical specimens. Prostate volume measured by magnetic resonance has been increasingly used in the clinical practice, and its value enables appropriate therapeutic planning and control of patients.
