Preliminaries to artificial consciousness: A multidimensional heuristic approach.

The pursuit of artificial consciousness requires conceptual clarity to navigate its theoretical and empirical challenges. This paper introduces a composite, multilevel, and multidimensional model of consciousness as a heuristic framework to guide research in this field. Consciousness is treated as a complex phenomenon, with distinct constituents and dimensions that can be operationalized for study and for evaluating their replication.

Trajectories of adolescents living with vertical transmission-HIV virus.

This study analyzes the life stories of eight young people living with vertically transmitted HIV in order to understand their perceptions marked by secrecy and silence regarding their experiences with the virus. Conducted at a specialized outpatient clinic in Rio de Janeiro, the study adopted circle dance, a Complementary and Integrative Health Practice, as a care tool. Using a qualitative approach and Life History as a data collection method, the focus was to understand the youth's experiences related to the disease and the crucial aspects of their lives.

Analysis of CenKR essentiality in Sinorhizobium meliloti and its activity at a target gene promoter in vivo.

The two-component regulatory system CenK-CenR has recently emerged as a regulator of cell envelope and cell division processes in the alpha-proteobacteria. In Sinorhizobium meliloti, CenK-CenR regulates the expression of SrlA, a thioredoxin-domain protein of unknown function. Deletion of srlA causes sensitivity to salt and oxidizing agents on solid growth medium.

Acute Kidney Injury and Electrolyte Imbalances Caused by Dapagliflozin Short-Term Use.

Dapagliflozin, a sodium-glucose cotransporter 2 inhibitor (SGLT2i), has shown demonstrated benefits for renal and cardiovascular outcomes in large clinical trials. However, short-term concerns regarding its impact on renal function and electrolyte balance exist. This study aimed to evaluate the short-term effects of dapagliflozin on renal function and electrolyte balance in patients newly prescribed the medication.

From images to insights: a neuroradiologist's practical guide on white matter fiber tract anatomy and DTI patterns for pre-surgical planning.

Introduction: Diffusion tensor imaging (DTI) is a valuable non-invasive imaging modality for mapping white matter tracts and assessing microstructural integrity, and can be used as a "biomarker" in diagnosis, differentiation, and therapeutic monitoring. Although it has gained clinical importance as a marker of neuropathology, limitations in its interpretation underscore the need for caution.

Methods: This review provides an overview of the principles and clinical applicability of DTI.

Vertebral artery dissection as the underlying cause of ventral spinal epidural haematoma.

Spontaneous spine epidural haematoma is a rare occurrence, with an incidence of 0.1/100 000 inhabitants/year. The anterior location of the haematoma is very uncommon since the dural sac is firmly attached to the posterior longitudinal ligament.

Carotid free-floating thrombus in patients with acute ischaemic stroke and active cancer.

In patients with ischaemic stroke, a carotid free-floating thrombus (CFFT) raises diagnostic and therapeutic challenges. We describe two women, each taking tamoxifen for invasive non-metastatic breast cancer, who developed large-vessel occlusion ischaemic strokes. The first had a CFFT 24 hours after receiving intravenous thrombolysis and mechanical thrombectomy; the thrombus completely resolved after 1 week of therapeutic anticoagulation.

The protective effect of breastfeeding on febrile seizures: a systematic review with meta-analysis.

Several potential risk factors have been identified in the etiopathogenesis of febrile seizures (FS), including the type and extent of breastfeeding (BF). Given the lack of conclusive data, this study aims to systematically evaluate the evidence on the association between BF and FS. We conducted a systematic review and meta-analysis according to PRISMA guidelines.

Drive competition underlies effective allostatic orchestration.

Living systems ensure their fitness by self-regulating. The optimal matching of their behavior to the opportunities and demands of the ever-changing natural environment is crucial for satisfying physiological and cognitive needs. Although homeostasis has explained how organisms maintain their internal states within a desirable range, the problem of orchestrating different homeostatic systems has not been fully explained yet.

Insomnia in older HIV-positive patients.

Introduction: Insomnia is a common sleep disorder in elderly. Although the HIV-positive population have a similar life expectancy when compared to the general population, some factors may interact with immunity conditions and therefore contribute to a worse prognosis.

Objective: This is a review of literature that aims to identify prevalence of insomnia in older HIV-positive patients.

["That was where the story started...": psychosocial frailty in the Zika virus epidemic].

The article focuses on the experience of family and social frailty of children with congenital Zika virus syndrome (CZVS) and discusses the changes in support networks, in the sense of both their capacities and shortcomings. This qualitative study adopted a clinical-psychosociological approach. The study analyzed family narratives in 32 group meetings conducted in an outpatient setting in a referral research institute for CZVS care in the State of Rio de Janeiro, Brazil.

The D allele of angiotensin-converting enzyme gene is associated with a worse autonomic heart control in community-based older adults.

The relationship between the Renin-Angiotensin-Aldosterone System (RAAS) and modulation of the Autonomic Nervous System (ANS) is reported as complex and bidirectional. Thus, the present study aimed to compare autonomous heart control, through symbolic analysis parameters, in the older adults carrying different ACE I/D gene polymorphisms (rs4646994). Two hundred four older adults comprised the study population and were grouped according to the ACE I/D gene polymorphism: II + ID genotype and DD genotype.

Hyperuricemia is associated with sympathovagal imbalance in older adults.

Purpose: This study aimed to compare heart rate variability (HRV) parameters obtained through symbolic analysis (SA), between older adults with and without hyperuricemia.

Methods: This is a cross-sectional study including 202 community-dwelling old adults, which was clinically stratified as with or without hyperuricemia, according to the cutoff point of serum uric acid ≥ 6 mg/dL for women and ≥ 7 mg/dL for men. Successive RR intervals were recorded along 5 min and analyzed with SA method.

Modeling the formation of social conventions from embodied real-time interactions.

What is the role of real-time control and learning in the formation of social conventions? To answer this question, we propose a computational model that matches human behavioral data in a social decision-making game that was analyzed both in discrete-time and continuous-time setups. Furthermore, unlike previous approaches, our model takes into account the role of sensorimotor control loops in embodied decision-making scenarios. For this purpose, we introduce the Control-based Reinforcement Learning (CRL) model.

Enriching Rotifers with "Premium" Microalgae: Rhodomonas lens.

The nutritional value of the marine cryptophyte Rhodomonas lens for the filter feeder Brachionus plicatilis as well as its biotechnological potential as a source of phycoerythrin (PE) and polyunsaturated fatty acids (PUFA) were evaluated in semi-continuous cultures maintained with different daily renewal rates (RR), from 10% (R10) to 50% (R50) of the total volume. Steady-state cell density decreased from 22 to 7 × 10 cells mL with increasing RR, with the maximum cell productivity, nearly 0.4 g L day, observed with R40.

Congenital Zika virus syndrome in infants: repercussions for the promotion of families' mental health.

This article aims to discuss the impacts of the promotion of families' mental health following the diagnosis of Zika virus infection in the pregnant woman and/or congenital Zika virus syndrome (CZVS) in the infant. The study also aims to foster reflection on mother-infant bonding in this context. The study is relevant not only because there is still so much to learn about CZVS, with its enormous capacity for dispersion and many doubts as to the physical consequences and psychological impacts, but also due to the urgent need to provide families and/or caregivers with guidelines for care and alternatives for dealing with the illness.
