Trauma is a risk factor for early-onset (EOP) and adult-onset (AOP) psychosis and is also associated with other psychiatric diagnoses and poorer fputcomes in the general population. We examined (1) whether trauma effects are specific to psychosis and (2) whether these effects differ between EOP and AOP.Linear regression models evaluated trauma exposure in two samples (EOP: 647 cases, 694 controls; AOP: 162 cases, 230 controls) as a function of psychotic and nonpsychotic psychiatric diagnosis (NPD) status. Parallel models assessed associations between trauma and symptom severity, global functioning, and cognition. Relative to individuals without psychiatric disorders, participants with psychosis and comorbid NPDs reported the greatest trauma exposure (EOP: β = 0.95; AOP: β = 1.1), followed by those with psychosis only (EOP: β = 0.67; AOP: β = 0.41) and NPDs only (EOP: β = 0.47; AOP: β = 0.36). Greater numbers of NPDs were associated with higher trauma exposure regardless of psychosis status (EOP: β = 0.15; AOP: β = 0.24). Trauma was associated with greater symptom severity (EOP: β = 0.13; AOP: β = 0.14) and poorer global functioning (EOP: β = −0.21; AOP: β = −0.13), but not cognition. No psychosis-by-trauma interactions were observed.Psychosis-specific effects were limited to greater trauma exposure, while trauma-related impacts on outcomes were similar across diagnostic groups. Findings were consistent across EOP and AOP. Results highlight the need for trauma-informed care in psychiatry given broad effects that influence disease course and prognosis.

Haemosporidians constitute a monophyletic group of vector-borne parasites that infect a wide range of vertebrate hosts, including Neotropical lizards. The remarkable diversity of these host-parasite associations and inadequate research on certain parasite groups have resulted in controversial haemosporidian taxonomy. Herein, we rediscover erythrocytic and non-erythrocytic haemosporidians infecting golden tegus (Tupinambis teguixin) from Brazil and Colombia. The erythrocyte-inhabiting parasite belongs to Plasmodium sp., and the non-erythrocytic form was identified as Saurocytozoon tupinambi, previously attributed to the Family Leucocytozoidae. These non-pigmented haemosporidian parasites do not multiply in the blood. The relationships between the Saurocytozoon and Leucocytozoidae species were discussed for many years, especially during the 1970s. However, cytochrome b (cytb) sequences and the mitochondrial genomes recovered for this species strongly support classifying this parasite as a Plasmodium taxon. Therefore, we proposed a new combination for this parasite, Plasmodium (Saurocytozoon) tupinambi comb. nov., where Saurocytozoon is retained as a subgenus due to its distinct morphology. These results reinforce that a broader definition of Plasmodiidae must include saurian parasites that develop non-pigmented leucocytozoid-like gametocytes.

From early on, infants show a preference for infant-directed speech (IDS) over adult-directed speech (ADS), and exposure to IDS has been correlated with language outcome measures such as vocabulary. The present multi-laboratory study explores this issue by investigating whether there is a link between early preference for IDS and later vocabulary size. Infants’ preference for IDS was tested as part of the ManyBabies 1 project, and follow-up CDI data were collected from a subsample of this dataset at 18 and 24 months. A total of 341 (18 months) and 327 (24 months) infants were tested across 21 laboratories. In neither preregistered analyses with North American and UK English, nor exploratory analyses with a larger sample did we find evidence for a relation between IDS preference and later vocabulary. We discuss implications of this finding in light of recent work suggesting that IDS preference measured in the laboratory has low test-retest reliability.

The paper describes the development of a short Spanish-language version of the General Well-Being Questionnaire (GWBQ; Cox & Gotts, 1987), based on the 12 items of its Worn Out scale. Research has shown the English-version Worn Out scale to be sensitive to aspects of the design and management of work. This study aimed to test its cross-cultural consistency in a Spanish-language workplace context. The data were collected from a sample of 229 workers in Valencia (Spain). Confirmatory Factor Analyses showed the factorial validity, reliability, and concurrent validity of the new Spanish version to be adequate. The sensitivity of the new measure to safety behavior and the reporting of accidents was also assessed and shown to be good. The new questionnaire extends the usefulness of the parent questionnaire to occupational health psychology research in the Spanish language by offering a short assessment tool appropriate for workplace studies.

Morphometric methods were used to study the great arterial trunks in a total of 22 human fetuses and newborn subjects weighing from 1 to 3.8 kg (mean 2.22 ± 0.85 kg). All specimens displayed concordant atrioventricular and ventriculoarterial connections, and all had perimembranous ventricular septal defects. Thirteen different parameters were measured in each specimen, comprising the orifices of the great arterial trunks, ascending aorta, vessels branching from the aortic arch, the aortic isthmus, descending aorta, pulmonary trunk, orifices of the pulmonary arteries, and arterial duct. The values were Compared with patterns of normality established in an earlier study using hearts from 496 human fetuses and neonates weighing form 60 to 5000 g. Minimum square regression analyses were used to study the relationships between fetal and neonatal log body weight in kilograms, and the various cardiometric parameters. We believe that these morphometric data have immediate clinical and surgical applications in the treatment of fetal and neonatal cardiovascular disorders.

Morphometric methods were used to study hearts with perimembranous ventricular septal defects in 22 human fetuses and neonates weighing from one to 3.8 kg (2.221±0.852 kg). All specimens displayed concordant atrioventricular and ventriculoarterial connections, and all had perimembranous ventricular septal defects. A total of 17 interventricular parameters (nine in the right ventricle and eight in the left) were measured in each specimen. The values were compared with patterns of normality established by Rowlatt and her colleagues in hearts from 83 children ranging in age from birth to 15 years. These patterns were found to be less reliable than our own data from fetal and perinatal hearts from children ranging in age from birth to one month. Our morphological data, when appropriately interpreted, have immediate clinical and surgical applications in the treatment of fetal and perinatal cardiovascular disorders.

Microdissection of the oval fossa from its right and left atrial aspects showed that the rim of the fossa was formed from an infolding of the atrial wall, which began between the base of the superior caval vein and the insertion of the right pulmonary vein to the left atrium. Because the rim varied in shape from circular to oval, we used morphometric methods to obtain patterns of normality of the diameters of the oval fossa, oval foramen, and the area of right and left atrial aspects of the septum. These values were found to correlate with log fetal and neonatal weight. Due to technical advances in prenatal diagnosis, these structures can now be examined in fetal life. Therefore, our morphometric data, when appropriately interpreted, have immediate clinical and surgical applications in the treatment of fetal and neonatal cardiovascular disorders.
