Proposta para uma nova versão brasileira de seis itens da Escala de Depressão Pós-Parto de Edimburgo

Introdução: a análise fatorial da Escala de Depressão Pós-Parto de Edimburgo (Edinburgh Postnatal Depression Scale, EPDS) poderia resultar em uma ferramenta de triagem mais curta e mais fácil de aplicar. Portanto, o objetivo deste estudo foi verificar e comparar as métricas de duas subescalas EPDS de 6 itens. Métodos: administramos a EPDS a um total de 3.891 mulheres que deram à luz entre 1 e 3 meses antes da aplicação. Foram realizadas análises fatoriais confirmatórias e exploratórias e geradas curvas ROC (receiver-operating characteristics) para determinar, respectivamente, a validade do construto, o ajuste dos itens da escala aos dados, e os pontos de corte ideais para as versões curtas. Resultados: a escala de 6 itens previamente publicada não apresentou validade de construto para nossa amostra. No entanto, utilizamos a análise fatorial exploratória para derivar uma nova escala de 6 itens, que apresentou boa validade de construto. A área sob a curva ROC da nova escala de 6 itens foi 0,986, e o ponto de corte ideal foi ≥ 6. Conclusão: a nova escala de 6 itens possui propriedades psicométricas adequadas e valores de curva ROC semelhantes à versão de 10 itens e oferece um meio de reduzir o custo e o tempo necessário para administrar o instrumento.Introduction: factor analysis of the Edinburgh Postnatal Depression Scale (EPDS) could result in a shorter and easier to handle screening tool. Therefore, the aim of this study was to check and compare the metrics of two different 6-item EPDS subscales. Methods: we administered the EPDS to a total of 3,891 women who had given birth between 1 and 3 months previously. We conducted confirmatory and exploratory factor analyses and plotted receiver-operating characteristics (ROC) curves to, respectively, determine construct validity, scale items' fit to the data, and ideal cutoff scores for the short versions. Results: a previously defined 6-item scale did not exhibit construct validity for our sample. Nevertheless, we used exploratory factor analysis to derive a new 6-item scale with very good construct validity. The area under the ROC curve of the new 6-item scale was 0.986 and the ideal cutoff score was ≥ 6. Conclusions: the new 6-item scale has adequate psychometric properties and similar ROC curve values to the10-item version and offers a means of reducing the cost and time taken to administer the instrument

Exérese laparoscópica de um schwannoma retroperitoneal: um caso clínico e revisão da literatura

ResumoIntroduçãoOs schwannomas retroperitoneais são tumores raros, maioritariamente benignos e com origem na bainha dos nervos periféricos. O diagnóstico pré‐operatório correto é frequentemente impossível. São raras as descrições de exérese laparoscópica de schwannomas nesta topografia. Pretendemos apresentar um caso de um schwannoma retroperitoneal tratado por via laparoscópica.MétodosHomem de 61 anos, com um achado acidental por ecografia de natureza sólida retroperitoneal. A tomografia computadorizada e a ressonância magnética revelaram uma lesão nodular, de contornos bem definidos, heterogénea, com 3cm de diâmetro, junto ao psoas maior. Foi realizada uma exérese do tumor por via laparoscópica transperitoneal.ResultadosO tempo operatório foi de 65 minutos, não se registando qualquer complicação perioperatória. O resultado histopatológico revelou um schwannoma benigno. Ao segundo ano de seguimento o doente encontra‐se sem recidivas.DiscussãoOs schwannomas retroperitoneais são difíceis de diagnosticar pré‐operatoriamente. O diagnóstico e o tratamento de escolha é a exérese cirúrgica. A abordagem laparoscópica dos schwannomas retroperitoniais confere menor invasividade, é segura e reprodutível, sobretudo porque são lesões bem delimitadas e hipovasculares que podem ser facilmente dissecadas das estruturas adjacentes.AbstractIntroductionRetroperitoneal schwannomas are rare, usually benign tumours that originate in the peripheral neural sheath. Preoperative diagnosis is often impossible. Few cases of laparoscopic removal of retroperitoneal schwannoma have been reported to date. We aim to report a case of retroperitoneal schwannoma using laparoscopic surgical technique.MethodsA 61‐year‐old man was found incidentally a solid retroperitoneal tumour by ultrasound. Abdominal computed tomography and magnetic ressonance imaging revealed a well‐defined, heterogeneous tumour, 3cm in diameter, in pararrenal space close to psoas major. A transperitoneal laparoscopic resection was performed.ResultsOperative time was 65minutes. The patient had an uneventful perioperative course. Histopathological exam revealed a benign schwannoma. No recurrence was detected after 2 years of follow‐up.DiscussionPreoperative establishment of diagnosis is difficult in case of retroperitoneal schwannomas even with imagiologic or biopsy studies. Complete resection is the diagnosis and treatment of choice. Laparoscopic treatment is minimal invasive, safe and feasible for retroperitoneal schwannomas mainly because these lesions are well limited and hypovascular, allowing a careful dissection from adjacent structures through an improved visualization

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation.

Comparison of major depression diagnostic classification probability using the SCID, CIDI, and MINI diagnostic interviews among women in pregnancy or postpartum: An individual participant data meta‐analysis

OBJECTIVES: A previous individual participant data meta-analysis (IPDMA) identified differences in major depression classification rates between different diagnostic interviews, controlling for depressive symptoms on the basis of the Patient Health Questionnaire-9. We aimed to determine whether similar results would be seen in a different population, using studies that administered the Edinburgh Postnatal Depression Scale (EPDS) in pregnancy or postpartum. METHODS: Data accrued for an EPDS diagnostic accuracy IPDMA were analysed. Binomial generalised linear mixed models were fit to compare depression classification odds for the Mini International Neuropsychiatric Interview (MINI), Composite International Diagnostic Interview (CIDI), and Structured Clinical Interview for DSM (SCID), controlling for EPDS scores and participant characteristics. RESULTS: Among fully structured interviews, the MINI (15 studies, 2,532 participants, 342 major depression cases) classified depression more often than the CIDI (3 studies, 2,948 participants, 194 major depression cases; adjusted odds ratio [aOR] = 3.72, 95% confidence interval [CI] [1.21, 11.43]). Compared with the semistructured SCID (28 studies, 7,403 participants, 1,027 major depression cases), odds with the CIDI (interaction aOR = 0.88, 95% CI [0.85, 0.92]) and MINI (interaction aOR = 0.95, 95% CI [0.92, 0.99]) increased less as EPDS scores increased. CONCLUSION: Different interviews may not classify major depression equivalently

Mammals in Portugal: a data set of terrestrial, volant, and marine mammal occurrences in Portugal

Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information on their distribution is crucial to delineate and support conservation actions. MAMMALS IN PORTUGAL is a publicly available data set compiling unpublished georeferenced occurrence records of 92 terrestrial, volant, and marine mammals in mainland Portugal and archipelagos of the Azores and Madeira that includes 105,026 data entries between 1873 and 2021 (72% of the data occurring in 2000 and 2021). The methods used to collect the data were: live observations/captures (43%), sign surveys (35%), camera trapping (16%), bioacoustics surveys (4%) and radiotracking, and inquiries that represent less than 1% of the records. The data set includes 13 types of records: (1) burrows | soil mounds | tunnel, (2) capture, (3) colony, (4) dead animal | hair | skulls | jaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8), observation in shelters, (9) photo trapping | video, (10) predators diet | pellets | pine cones/nuts, (11) scat | track | ditch, (12) telemetry and (13) vocalization | echolocation. The spatial uncertainty of most records ranges between 0 and 100 m (76%). Rodentia (n =31,573) has the highest number of records followed by Chiroptera (n = 18,857), Carnivora (n = 18,594), Lagomorpha (n = 17,496), Cetartiodactyla (n = 11,568) and Eulipotyphla (n = 7008).

A proposal for a new Brazilian six-item version of the Edinburgh Postnatal Depression Scale

Abstract Introduction: Factor analysis of the Edinburgh Postnatal Depression Scale (EPDS) could result in a shorter and easier to handle screening tool. Therefore, the aim of this study was to check and compare the metrics of two different 6-item EPDS subscales.

We conducted confirmatory and exploratory factor analyses and plotted receiver-operating characteristics (ROC) curves to, respectively, determine construct validity, scale items' fit to the data, and ideal cutoff scores for the short versions. Results: A previously defined 6-item scale did not exhibit construct validity for our sample. Nevertheless, we used exploratory factor analysis to derive a new 6-item scale with very good construct validity. The area under the ROC curve of the new 6-item scale was 0.986 and the ideal cutoff score was ≥ 6.

Population histories and genomic diversity of South American natives

South America is home to one of the most culturally diverse present-day native populations. However, the dispersion pattern, genetic substructure, and demographic complexity within South America are still poorly understood. Based on genome-wide data of 58 native populations, we provide a comprehensive scenario of South American indigenous groups considering the genomic, environmental, and linguistic data. Clear patterns of genetic structure were inferred among the South American natives, presenting at least four primary genetic clusters in the Amazonian and savanna regions and three clusters in the Andes and Pacific coast. We detected a cline of genetic variation along a west-east axis, contradicting a hard Andes-Amazon divide. This longitudinal genetic variation seemed to have been shaped by both serial population bottlenecks and isolation by distance. Results indicated that present-day South American substructures recapitulate ancient macroregional ancestries and western Amazonia groups show genetic evidence of cultural exchanges that led to language replacement in precontact times. Finally, demographic inferences pointed to a higher resilience of the western South American groups regarding population collapses caused by the European invasion and indicated precontact population reductions and demic expansions in South America

Data-driven methods distort optimal cutoffs and accuracy estimates of depression screening tools: a simulation study using individual participant data

Objective: To evaluate, across multiple sample sizes, the degree that data-driven methods result in (1) optimal cutoffs different from population optimal cutoff and (2) bias in accuracy estimates. Study design and setting: A total of 1,000 samples of sample size 100, 200, 500 and 1,000 each were randomly drawn to simulate studies of different sample sizes from a database (n = 13,255) synthesized to assess Edinburgh Postnatal Depression Scale (EPDS) screening accuracy. Optimal cutoffs were selected by maximizing Youden's J (sensitivity+specificity–1). Optimal cutoffs and accuracy estimates in simulated samples were compared to population values. Results: Optimal cutoffs in simulated samples ranged from ≥ 5 to ≥ 17 for n = 100, ≥ 6 to ≥ 16 for n = 200, ≥ 6 to ≥ 14 for n = 500, and ≥ 8 to ≥ 13 for n = 1,000. Percentage of simulated samples identifying the population optimal cutoff (≥ 11) was 30% for n = 100, 35% for n = 200, 53% for n = 500, and 71% for n = 1,000. Mean overestimation of sensitivity and underestimation of specificity were 6.5 percentage point (pp) and -1.3 pp for n = 100, 4.2 pp and -1.1 pp for n = 200, 1.8 pp and -1.0 pp for n = 500, and 1.4 pp and -1.0 pp for n = 1,000. Conclusions: Small accuracy studies may identify inaccurate optimal cutoff and overstate accuracy estimates with data-driven methods.</p
