Factors associated with satisfaction and perceived helpfulness of mental healthcare: a World Mental Health Surveys report.

BACKGROUND: Mental health service providers are increasingly interested in patient perspectives. We examined rates and predictors of patient-reported satisfaction and perceived helpfulness in a cross-national general population survey of adults with 12-month DSM-IV disorders who saw a provider for help with their mental health. METHODS: Data were obtained from epidemiological surveys in the World Mental Health Survey Initiative. Respondents were asked about satisfaction with treatments received from up to 11 different types of providers (very satisfied, satisfied, neither satisfied nor dissatisfied, somewhat dissatisfied, very dissatisfied) and helpfulness of the provider (a lot, some, a little, not at all). We modelled predictors of satisfaction and helpfulness using a dataset of patient-provider observations (n = 5,248). RESULTS: Most treatment was provided by general medical providers (37.4%), psychiatrists (18.4%) and psychologists (12.7%). Most patients were satisfied or very satisfied (65.9-87.5%, across provider) and helped a lot or some (64.4-90.3%). Spiritual advisors and healers were most often rated satisfactory and helpful. Social workers in human services settings were rated lowest on both dimensions. Patients also reported comparatively low satisfaction with general medical doctors and psychiatrists/psychologists and found general medical doctors less helpful than other providers. Men and students reported lower levels of satisfaction than women and nonstudents. Respondents with high education reported higher satisfaction and helpfulness than those with lower education. Type of mental disorder was unrelated to satisfaction but in some cases (depression, bipolar spectrum disorder, social phobia) was associated with low perceived helpfulness. Insurance was unrelated to either satisfaction or perceived helpfulness but in some cases was associated with elevated perceived helpfulness for a given level of satisfaction. CONCLUSIONS: Satisfaction with and perceived helpfulness of treatment varied as a function of type of provider, service setting, mental status, and socio-demographic variables. Invariably, caution is needed in combining data from multiple countries where there are cultural and service delivery variations. Even so, our findings underscore the utility of patient perspectives in treatment evaluation and may also be relevant in efforts to match patients to treatments.

Population genetics and genomics of Triatoma brasiliensis (Hemiptera, Reduviidae) in an area of high pressure of domiciliary infestation in Northeastern Brazil.

Understanding the population dynamics of vectors is crucial for effective control of vector-borne diseases. In the Northeastern Brazilian semi-arid region, Triatoma brasiliensis persists as the most significant Chagas disease vector, frequently displaying recurrent domiciliary infestations. This situation raises relevant public health concerns in the municipality of Currais Novos in the state of Rio Grande do Norte. This area has experienced a high prevalence of peridomiciliary re-infestations by T. brasiliensis, coupled with elevated rates of Trypanosoma cruzi infection. Therefore, we assessed the distribution of genetic variation via mitochondrial Cytochrome b gene (MT-CYB) sequencing (n = 109) and single nucleotide polymorphisms (SNPs, n = 86) to assess the gene flow among distinct populations distributed in varied geographic spots and environments, mainly sylvatic and peridomiciliary. Insects were collected from rural communities at Currais Novos, enclosed within a 16 km radius. Sampling included 13 populations: one intradomiciliary, eight peridomiciliary, and four sylvatic. Furthermore, an external population located 220 km from Currais Novos was also included in the study. The method employed to obtain SNP information relied on ddRAD-seq genotyping-by-sequencing (GBS), enabling a genome-wide analysis to infer genetic variation. Through AMOVA analysis of MT-CYB gene variation, we identified four distinct population groups with statistical significance (FCT= 0.42; p<0.05). We identified a total of 3,013 SNPs through GBS, with 11 loci showing putative signs of being under selection. The variation based on 3,002 neutral loci evidenced low genetic structuration based on low FST values (p>0.05), indicating local panmixia. However, resampling algorithms pointed out that three samples from the external population were assigned (>98 %) in a cluster contrasting from the ones putatively under local panmixia - validating the newly applied genome-wide marker for studies on the population genetics at finer-scale resolution for T. brasiliensis. The presence of population structuring in some of the sampled points, as suggested by the mitochondrial marker, leads us to assume that infestations were probably initiated by small populations of females - demographic event poses a risk for rapid re-infestations. The local panmictic pattern revealed by the GBS marker poses a challenge for vector control measures, as re-infestation foci may be distributed over a wide geographical and ecological range. In such instances, vectors exhibit reduced susceptibility to conventional insecticide spraying operations since sylvatic populations are beyond the reach of these interventions. The pattern of infestation exhibited by T. brasiliensis necessitates integrating innovative strategies into the existing control framework, holding the potential to create a more resilient and adaptive vector control program. In our dataset, the results demonstrated that the genetic signals from both markers were complementary. Therefore, it is essential to consider the nature and inheritance pattern of each marker when inferring the pattern of re-infestations.

Severe COVID-19 and long COVID are associated with high expression of STING, cGAS and IFN-α.

The cGAS-STING pathway appears to contribute to dysregulated inflammation during coronavirus disease 2019 (COVID-19); however, inflammatory factors related to long COVID are still being investigated. In the present study, we evaluated the association of cGAS and STING gene expression levels and plasma IFN-α, TNF-α and IL-6 levels with COVID-19 severity in acute infection and long COVID, based on analysis of blood samples from 148 individuals, 87 with acute COVID-19 and 61 in the post-COVID-19 period. Quantification of gene expression was performed by real-time PCR, and cytokine levels were quantified by ELISA and flow cytometry. In acute COVID-19, cGAS, STING, IFN-α, TNF-α, and IL-6 levels were higher in patients with severe disease than in those with nonsevere manifestations (p < 0.05). Long COVID was associated with elevated cGAS, STING and IFN-α levels (p < 0.05). Activation of the cGAS-STING pathway may contribute to an intense systemic inflammatory state in severe COVID-19 and, after infection resolution, induce an autoinflammatory disease in some tissues, resulting in long COVID.

From molecules to ecosystems: Insights into a network of interactions for a Chagas disease outbreak using Triatoma brasiliensis as natural samplers.

Exploring the dynamics of disease transmission involves an understanding of complex interactions within the eco-epidemiologic framework. In the context of Chagas disease (CD), elements are mainly represented by the interactions among the pathogen, insect vector, host, humans and the environment. We performed quantitative and qualitative analyses on a dataset derived from 98 Triatoma brasiliensis infected by trypanosomatids, which were linked to a CD outbreak in the semi-arid region of northeastern Brazil. We extracted invertebrate-derived DNA (iDNA) from these insects, comprising 18 populations around the outbreak area, each indicative of various strata of anthropogenic influence. Food source (FS) diversity, representing potential parasite reservoirs, was determined through mitochondrial gene (cyt b) sequencing of vertebrates, and parasite genotyping was accessed using fluorescent amplified fragment barcodes (FFLB) of trypanosomatids. We also assessed the residents' awareness of breeding sites for CD vectors in the inspected houses. The quantification of Trypanosoma cruzi was estimated via real-time PCR and is denominated here as the average parasite load (PL) per insect (T. cruzi/intestinal unit). We aimed to address vector-parasite-host-environment interactions that were discussed based on their significance among the components. Notably, among the significant interactions, we observed that the PL in the insects was significantly influenced by FS. Infected insects that fed on the classic reservoir, Didelphis albiventris, and Galea spixii exhibited higher PLs, compared to those that fed on Kerodon rupestris (p < 0.04)-a primary host. While D. albiventris is already recognized as a synanthropic species, we propose that G. spixii may also be undergoing a synanthropic process. Conversely, domestic cats are frequently identified as FS in infected insects from the sylvatic environment, suggesting a possible change in their behavior towards a wild state. Therefore, we propose that neglected anthropogenic actions have facilitated the reciprocal (sylvatic-peridomestic) circulation of T. cruzi-especially noted for TcI because it was predominant in insects found in peridomestic environments. Residents are often unaware of the existence of insect breeding grounds near their homes, particularly when it involves the storage of materials without planning for use, such as piles of tiles, bricks and wood. Although indirect inferences about the interaction among vector-parasite-host-environment are still incipient, we highlight the potential use of vectors as natural samplers of biological and ecological components in transmitting the disease.

Patterns, predictors, and patient-reported reasons for antidepressant discontinuation in the WHO World Mental Health Surveys.

BACKGROUND: Despite their documented efficacy, substantial proportions of patients discontinue antidepressant medication (ADM) without a doctor's recommendation. The current report integrates data on patient-reported reasons into an investigation of patterns and predictors of ADM discontinuation. METHODS: Face-to-face interviews with community samples from 13 countries (n = 30 697) in the World Mental Health (WMH) Surveys included n = 1890 respondents who used ADMs within the past 12 months. RESULTS: 10.9% of 12-month ADM users reported discontinuation-based on recommendation of the prescriber while 15.7% discontinued in the absence of prescriber recommendation. The main patient-reported reason for discontinuation was feeling better (46.6%), which was reported by a higher proportion of patients who discontinued within the first 2 weeks of treatment than later. Perceived ineffectiveness (18.5%), predisposing factors (e.g. fear of dependence) (20.0%), and enabling factors (e.g. inability to afford treatment cost) (5.0%) were much less commonly reported reasons. Discontinuation in the absence of prescriber recommendation was associated with low country income level, being employed, and having above average personal income. Age, prior history of psychotropic medication use, and being prescribed treatment from a psychiatrist rather than from a general medical practitioner, in comparison, were associated with a lower probability of this type of discontinuation. However, these predictors varied substantially depending on patient-reported reasons for discontinuation. CONCLUSION: Dropping out early is not necessarily negative with almost half of individuals noting they felt better. The study underscores the diverse reasons given for dropping out and the need to evaluate how and whether dropping out influences short- or long-term functioning.

Fatores associados à depressão e ansiedade em nutricionistas na pandemia por COVID-19 / Factors associated with depression and anxiety in nutritionists in the COVID-19 pandemic

O objetivo foi investigar os fatores associados à depressão e/ou ansiedade em nutricionistas durante a pandemia por COVID-19. Estudo transversal com aplicação das escalas GAD-7 e PHQ-9. Dos 1.018 participantes 60,2% manifestaram rastreio positivo para depressão e/ou ansiedade, com maior força de associação para conflitos muito frequentes nas relações (OR = 11,11; IC95% 6,61;18,67), uso de medicação para dor (OR = 7,42; IC95% 4,67;11,79) e pensar sempre sobre a pandemia (OR = 6,5; IC95% 4,14;10,32). Não estar em tratamento psicoterápico (OR = 0,39; IC95% 0,27;0,560) e não estar em uso de medicamento psicotrópico (OR = 0,40; IC95% 0,26;0,60) foram associados a menores chances de rastreio positivo. O estudo resulta em conhecimento epidemiológico aplicável a ações de vigilância, prevenção e controle da ansiedade e depressão entre nutricionistas.

The objective was to investigate the factors associated with depression and/or anxiety and depression in nutritionists during the COVID-19 pandemic. Cross-sectional study with the application of the GAD-7 and PHQ-9 scales. 1,018 participated, of which 60.2% showed positive screening for depression and/or anxiety, with a greater strength of association for very frequent conflicts in relationships (OR = 11.11; 95%CI 6.61;18.67), use of pain medication (OR = 7.42; 95%CI 4.67;11.79) and always thinking about the pandemic (OR = 6.5; 95%CI 4.14;10.32). Not being under psychotherapeutic treatment (OR = 0.39; 95%CI 0.27;0.560) and not using psychotropic medication (OR = 0.40; 95%CI 0.26;0.60) were associated with lower odds of positive screening. This study results in epidemiological knowledge applicable to surveillance, prevention and control of anxiety and depression among nutritionists.

A trial-based cost-effectiveness analysis of antibiotic prescription strategies for non-complicated respiratory tract infections in children.

BACKGROUND: Antibiotic prescription for respiratory tract infections (RTIs) in children attending primary care centres is almost double that predicted according to bacterial prevalence. Delayed antibiotic prescription (DAP) is designed to deploy a more rational use of antibiotics. While studies have evaluated DAP efficacy and safety for children with RTIs, little research has been conducted on the economic implications. METHODS: Our trial compared cost-effectiveness for DAP, immediate antibiotic prescription (IAP), and no antibiotic prescription (NAP) for children aged 2-14 years with acute uncomplicated RTIs attended to in 39 primary care centres in Spain. The main outcome was the incremental cost-effectiveness ratio (ICER), measured in euros per gained quality-adjusted life days (QALDs). Net monetary benefit (NMB) was also calculated as a tool for decision making. The analysis was performed from a societal perspective for a time horizon of 30 days, and included healthcare direct costs, non-healthcare direct and indirect costs, and the antimicrobial resistance (AMR) cost. RESULTS: DAP was the most cost-effective strategy, even when the cost of AMR was included. QALD values for the three strategies were very similar. IAP compared to DAP was more costly (109.68 vs 100.90 euros) and similarly effective (27.88 vs 27.94 QALDs). DAP compared to NAP was more costly (100.90 vs 97.48 euros) and more effective (27.94 vs. 27.82 QALDs). The ICER for DAP compared to NAP was 28.84 euros per QALD. The deterministic sensitivity analysis indicated that non-healthcare indirect costs had the greatest impact on the ICER. The cost-effectiveness acceptability curve showed that DAP was the preferred option in approximately 81.75% of Monte Carlo iterations, assuming a willingness-to-pay value of 82.2 euros per gained QALD. CONCLUSIONS: When clinicians are in doubt about whether an antibiotic is needed for children with RTIs attending PC centres, those treated with the DAP strategy will have slightly better efficiency outcomes than those treated with IAP because its costs are lower than those of IAP. DAP is also the most cost-effective strategy over a time horizon of 30 days if AMR is considered, despite higher short-term costs than NAP. However, if in the long term the costs of AMR are larger than estimated, NAP could also be an alternative strategy. TRIAL REGISTRATION: This trial has been registered at www. CLINICALTRIALS: gov (identifier NCT01800747; Date: 28/02/2013 (retrospectively registered).

Use of brome mosaic virus-like particles in feed, to deliver dsRNA targeting the white spot syndrome virus vp28 gene, reduces Penaeus vannamei mortality.

Numerous strategies have been investigated to combat viral infections in shrimp, specifically targeting the white spot syndrome virus (WSSV) that has caused outbreaks worldwide since the 1990s. One effective treatment involves intramuscular application of dsRNA-mediated interference against the viral capsid protein VP28. However, this approach presents challenges in terms of individual shrimp management, limiting its application on a large scale. To address this, our study aimed to evaluate the efficacy of oral delivery of protected dsRNA using chitosan nanoparticles or virus-like particles (VLPs) synthesized in brome mosaic virus (BMV). These delivery systems were administered before, during, and after WSSV infection to assess their therapeutic potential. Our findings indicate that BMV-derived VLPs demonstrated superior efficiency as nanocontainers for dsRNA delivery. Notably, the treatment involving vp28 dsRNA mixed in the feed and administered simultaneously to shrimp already infected with WSSV exhibited the highest survival rate (48%), while the infected group had a survival rate of zero, suggesting the potential efficacy of this prophylactic approach in commercial shrimp farms.

Prevalence and variability of depressive symptoms in Europe: update using representative data from the second and third waves of the European Health Interview Survey (EHIS-2 and EHIS-3).

BACKGROUND: Assessing the prevalence of clinically relevant depressive symptoms and their possible variation by country and over time could be a valuable resource to inform the development of public health policies and preventive resources to reduce mental health burden. We aimed to assess cross-national differences in the point prevalence of clinically relevant depressive symptoms in Europe in 2018-20, and to evaluate point prevalence differences between countries and over time between 2013-15 and 2018-20. METHODS: In this population-based study, data from participants in the second and third waves of the European Health Interview Survey (EHIS-2 from 2013 to 2015 and EHIS-3 from 2018 to 2020) from 30 European countries were used (n=542 580). From the total sample, 283 692 participants belonging to EHIS-3 were included in the study (52·4% women and 47·5% men). The non-response in EHIS-3 ranged by country, from 12% to 78%. Point prevalence of clinically relevant depressive symptoms was evaluated using a cutoff score of 10 or more for the 8-item version of the Patient Health Questionnaire. Crude prevalence ratios and adjusted prevalence ratios (aPRs) were obtained to assess differences in the prevalence between countries and over time within countries. FINDINGS: The point prevalence of clinically relevant depressive symptoms in Europe in 2018-20 was 6·54% (95% CI 6·34-6·73), ranging across countries from 1·85% (1·53-2·17) in Greece to 10·72% (10·04-11·40) in Sweden. Compared with the other European countries, those with the lowest aPRs were Greece, Serbia, and Cyprus and those with the highest aPRs were Belgium, Slovenia, and Croatia. A small but significant increase in the prevalence between EHIS-2 and EHIS-3 was observed (aPR 1·11 [1·07-1·14]). A wide variability over time in the point prevalence within countries was observed, ranging from an aPR of 0·63 (0·54-0·74) in Hungary to 1·88 (1·53-2·31) in Slovenia. INTERPRETATION: This study, based on large and representative datasets and a valid and reliable screening tool for the assessment of depression, indicates that the point prevalence of clinically relevant depressive symptoms in Europe from 2013 to 2020 remains relatively stable, with wide variability between countries. These findings could be considered a baseline for monitoring the prevalence of clinically relevant depressive symptoms in Europe, and could inform policy for the development of preventive strategies for depression both at a country and European level.

The performance of K6 as a screening tool for mood disorders: A population-based study of the São Paulo metropolitan area.

AIM: The use of screening instruments allows the detection of psychological and behavioural manifestations there are often not identified in users of health services. We evaluated the performance of the Kessler Psychological Distress Scale (K6) in identifying mood disorders (MD), using the Composite International Diagnostic Interview (CIDI) as gold-standard, in a population-based sample (n = 5037) of adult residents of metropolitan São Paulo. METHODS: Sensitivity, specificity, positive and negative predictive values, and accuracy were calculated to assess the performance of K6 in detecting 30-day CIDI MD. All cut-points for each disorder were analysed using the Youden index and the area under the receiver operating characteristic curve (AUC), and the best cut-points were identified. Cronbach's alpha was calculated to assess internal consistency. RESULTS: In total, 5.5% respondents screened positive for any MD (95% IC 4.84-6.14). A good detection performance was observed for all MD, with AUC values for any MD of 0.91 (95% IC 0.89-0.92), ranging from 0.80 (95% CI 0.71-0.98) for minor depression to 0.93 (95% CI 0.87-0.98) for bipolar I disorder. Best cut-points for each MD were identified, with overall sensitivity and specificity of 88.8% and 80.2%, respectively. Cronbach's alpha was 0.83. CONCLUSIONS: K6 is a good screening tool for MD in the Brazilian population. It is a brief and easy to use instrument that can promote the early identification and treatment of MD, reducing the burden of mental illness.

Phytochemical characterization, isolation, antioxidant and cytogenotoxic activity of leaves of Heliotropium elongatum (Lehm) I.M. Johnst.

Heliotropium elongatum is used to treat inflammation, cough, and flu. This study aimed to characterize the phytochemical profile and determine the total phenolic content (TPC), antioxidant and cytogenotoxic activity of the ethanolic extract (EE), and fractions of H. elongatum leaves. In the phytochemical profile analysis, organic acids, reducing sugars, flavonoids, saponins, anthraquinones, steroids/triterpenes, and depsides/depsidones were detected in the EE and/or fractions (hexanic/FH, chloroformic/FC, ethyl acetate/FAE, and hydromethanolic/FHM). The highest TPC and highest antioxidant activity (DPPH and ABTS) was detected in FHM. In FH, 16 compounds were identified by GC-MS, and ursolic acid was isolated by 1H NMR and 13C NMR. HPLC-DAD from EE, FAE, and FHM demonstrated characteristic wavelengths for flavonoids, flavonols, flavones, and anthraquinones. ESI-IT/MSn analysis of EE, FC, FAE, and FHM revealed alkaloids, steroids, terpenoids, flavonoids, and phenolic acids. In Allium cepa assay there was no significant cytotoxic effect initiated by EE (62.5 to 1,000 µg/ml), FHM (1,000 µg/ml), and FAE (62.5 µg/ml). Genotoxicity was evidenced only with EE at 500 and 1,000 µg/ml, and FHM (62.5 to 1,000 µg/ml) as evidenced by presence of micronuclei (MN) and nuclear buds (NB). Our results identified compounds of medicinal interest with antioxidant activity; however observed cytogenotoxic changes indicated the need for caution when using these compounds for therapeutic purposes.

Towards measuring effective coverage: critical bottlenecks in quality- and user-adjusted coverage for major depressive disorder in São Paulo metropolitan area, Brazil.

BACKGROUND: Major depressive disorder (MDD) contributes to a significant proportion of disease burden, disability, economic losses, and impact on need of treatment and health care in Brazil, but systematic information about its treatment coverage is scarce. This paper aims to estimate the gap in treatment coverage for MDD and identify key bottlenecks in obtaining adequate treatment among adult residents in the São Paulo Metropolitan area, Brazil. METHODS: A representative face-to-face household survey was conducted among 2942 respondents aged 18+ years to assess 12-month MDD, characteristics of 12-month treatment received, and bottlenecks to deliver care through the World Mental Health Composite International Diagnostic Interview. RESULTS: Among those with MDD (n = 491), 164 (33.3% [SE, 1.9]) were seen in health services, with an overall 66.7% treatment gap, and only 25.2% [SE, 4.2] received effective treatment coverage, which represents 8.5% of those in need, with a 91.5% gap in adequate care (66.4% due to lack of utilization and 25.1% due to inadequate quality and adherence). Critical service bottlenecks identified were: use of psychotropic medication (12.2 percentage points drop), use of antidepressants (6.5), adequate medication control (6.8), receiving psychotherapy (19.8). CONCLUSIONS: This is the first study demonstrating the huge treatment gaps for MDD in Brazil, considering not only overall coverage, but also identifying specific quality- and user-adjusted bottlenecks in delivering pharmacological and psychotherapeutic care. These results call for urgent combined actions focused in reducing effective treatment gaps within services utilization, as well as in reducing gaps in availability and accessibility of services, and acceptability of care for those in need.

Polymorphisms in the MBL2 gene are associated with the plasma levels of MBL and the cytokines IL-6 and TNF-α in severe COVID-19.

Introduction: Mannose-binding lectin (MBL) promotes opsonization, favoring phagocytosis and activation of the complement system in response to different microorganisms, and may influence the synthesis of inflammatory cytokines. This study investigated the association of MBL2 gene polymorphisms with the plasma levels of MBL and inflammatory cytokines in COVID-19. Methods: Blood samples from 385 individuals (208 with acute COVID-19 and 117 post-COVID-19) were subjected to real-time PCR genotyping. Plasma measurements of MBL and cytokines were performed by enzyme-linked immunosorbent assay and flow cytometry, respectively. Results: The frequencies of the polymorphic MBL2 genotype (OO) and allele (O) were higher in patients with severe COVID-19 (p< 0.05). The polymorphic genotypes (AO and OO) were associated with lower MBL levels (p< 0.05). IL-6 and TNF-α were higher in patients with low MBL and severe COVID-19 (p< 0.05). No association of polymorphisms, MBL levels, or cytokine levels with long COVID was observed. Discussion: The results suggest that, besides MBL2 polymorphisms promoting a reduction in MBL levels and therefore in its function, they may also contribute to the development of a more intense inflammatory process responsible for the severity of COVID-19.

Potentially inappropriate medications and cognitive performance: cross-sectional results from the ELSA-Brasil study.

OBJECTIVES: Potentially inappropriate medications (PIM), especially those with potential effects on the central nervous system, can increase the risk of cognitive impairment. We investigated the association of the use of PIM and PIM that may impair cognition (PIM-Cog) with cognitive performance among older adults. METHODS: In this cross-sectional study with 2,626 participants, PIM and PIM-Cog were defined by the 2019 American Geriatrics Society Beers criteria. We calculated global cognition and memory, verbal fluency, and Trail Making Test B version (TMT-B) z-scores. Linear regression models adjusted for sociodemographic and clinical variables were used to investigate the association between PIM and cognition. RESULTS: 27% and 7% of the sample (mean age = 65.1 ± 4.1 years old, 54% women, and 61% White) used at least one PIM and PIM-cog, respectively. PIM was associated with poor performance in the TMT-B (ß = -0.17, 95% Cl = -0.29; -0.05, p = 0.007). PIM-Cog was also associated with poor TMT-B performance (ß = -0.08, 95% Cl = -0.15; -0.01, p = 0.025). CONCLUSION: The use of PIM and PIM-Cog was associated with poor executive function among older adults. The review of PIM use and the deprescription of these drugs may be an effective way to improve cognitive function.

Association of Polymorphisms of IL-6 Pathway Genes (IL6, IL6R and IL6ST) with COVID-19 Severity in an Amazonian Population.

Interleukin-6 has been recognized as a major role player in COVID-19 severity, being an important regulator of the cytokine storm. Hence, the evaluation of the influence of polymorphisms in key genes of the IL-6 pathway, namely IL6, IL6R, and IL6ST, may provide valuable prognostic/predictive markers for COVID-19. The present cross-sectional study genotyped three SNPs (rs1800795, rs2228145, and rs7730934) at IL6. IL6R and IL6ST genes, respectively, in 227 COVID-19 patients (132 hospitalized and 95 non-hospitalized). Genotype frequencies were compared between these groups. As a control group, published data on gene and genotype frequencies were gathered from published studies before the pandemic started. Our major results point to an association of the IL6 C allele with COVID-19 severity. Moreover, IL-6 plasmatic levels were higher among IL6 CC genotype carriers. Additionally, the frequency of symptoms was higher at IL6 CC and IL6R CC genotypes. In conclusion, the data suggest an important role of IL6 C allele and IL6R CC genotype on COVID-19 severity, in agreement with indirect evidence from the literature about the association of these genotypes with mortality rates, pneumonia, and heightening of protein plasmatic levels pro-inflammatory driven effects.

Prevalence of depressive symptoms and its association with social support among older adults: The Brazilian National Health Survey.

BACKGROUND: The study aimed to assess the association between depressive symptoms and social support measures among non-institutionalized Brazilian older adults. METHODS: A cross-sectional study was carried out with data from the last National Health Survey, conducted in 2019. A descriptive analysis of the study variables was performed, followed by a multiple regression analysis to teste the association between the dependent variable (depressive symptoms, assessed by the Patient Health Questionnaire (PHQ-9) and independent variables (household arrangement, marital relationship, leisure activities, voluntary activity, religious activity, activities in associations/leaderships, work and receiving social support (friends and family). RESULTS: The sample comprised 22,723 older adults and 13.1 % had depressive symptoms. There was a positive relationship between the number of people in the household and the prevalence of depressive symptoms. Individuals with support from family members only (PR 0.69; 95 % CI 0.51; 0.92) and those with support from family and friends (PR 0.53 95 % CI 0.40; 0.70) had a lower prevalence of depressive symptoms than those without support. Participation in leisure and religious activities was inversely associated with depressive symptoms. A negative association was found between work and the presence of depressive symptoms (PR 0.83; 95 % CI 0.70; 0.99). LIMITATIONS: The cross-sectional design limits causal inferences and the survey did not include institutionalized individuals. CONCLUSIONS: The lower prevalence of the outcome among older adults with social support highlights the importance of evaluating these measures and practicing activities that allow personal and social interactions among this age group.

Association of preterm birth with poor metabolic outcomes in schoolchildren.

OBJECTIVE: To investigate, at school age, the metabolic profile of children born preterm. METHODS: A cross-sectional study of children 5 to 8 years old, born with gestational age (GA) < 34 weeks and/or weight ≤ 1,500 grams. Clinical and anthropometric data were assessed by a single trained pediatrician. Biochemical measurements were done at the organization's Central Laboratory using standard methods. Data on health conditions, eating, and daily life habits were retrieved from medical charts and through validated questionnaires. Binary logistic and linear regression models were built to identify the association between variables, weight excess, and GA. RESULTS: Out of 60 children (53.3% female), 6.8 ± 0.7 years old, 16.6% presented excess weight, 13.3% showed increased insulin resistance markers and 36.7% had abnormal blood pressure values. Those presenting excess weight had higher waist circumferences and higher HOMA-IR than normal-weight children (OR = 1.64; CI = 1.035-2.949). Eating and daily life habits were not different among overweight and normal-weight children. The small-for-gestational-age (SGA) and appropriate-for-gestational-age (AGA, 83.3%) birth weight children did not differ regarding clinical (body weight, blood pressure) or biochemical variables (serum lipids, blood glucose, HOMA-IR). CONCLUSION: Schoolchildren born preterm, regardless of being AGA or SGA, were overweight, and presented increased abdominal adiposity, reduced insulin sensitivity, and altered lipid profile, justifying longitudinal follow-up regarding adverse metabolic outcomes in the future.

Attitudes and Behaviors towards Vaccination in Portuguese Nursing Students.

Knowing the attitudes and behaviors of nursing students in relation to vaccination is important because they will soon be determinant for the health literacy of the population. Vaccination remains the most effective response in the fight against communicable diseases, including COVID-19 and influenza. The objective of this study is to analyze the attitudes and behaviors of Portuguese nursing students with regard to vaccination. A cross-sectional study was carried out, with data collection from nursing students at a university in Lisbon, Portugal. A sample of 216 nursing students was obtained, representing 67.1% of the students enrolled in this university. What stands out from the results of the questionnaire "Attitudes and Behaviors in Relation to Vaccination among Students of Health Sciences" is that for the majority of students the answers were positive; in addition, 84.7% had a completed vaccination schedule for COVID-19. Being a nursing student, being in the final years of the course and being a woman are the factors that most influence the positive attitude of the students. The results obtained are motivating, because these students will be the future health professionals most likely to integrate health promotion programs through vaccination.
