Abstract
We performed a single-centre, retrospective study to assess physiologic changes of infants in the cardiac ICU while being held by their parent. Continuous data streaming of vital signs were collected for infants included in the study from January 2021 to March 2022. Demographic and clinical characteristics were collected from the electronic medical record. The physiologic streaming data were analysed using mixed-effects models to account for repeated measures and quantify the effect of parental holding. Comparison analysis was also performed controlling for intubation, pre-operative versus post-operative status, and whether the holding was skin-to-skin or not. Ninety-five patients with complete physiologic data were included in the study. There were no immediate adverse events associated with holding. Heart rate decreased during the response time compared to its baseline value (p = 0.01), and this decrease was more pronounced for the non-intubated and pre-operative patients. The near-infrared spectroscopy-based venous saturation increased overall (p = 0.02) in patients while being held. We conclude that parental holding of infants in the cardiac ICU can be safely accomplished, and the haemodynamic and oximetric profile during the holding is favourable compared to the infants' baseline prior to holding.

Abstract
Good glycaemic control continues to be the most effective therapeutic manoeuvre to reduce the risk of development and/or progression of microvascular disease, and therefore remains the cornerstone of diabetes management despite recent scepticism about tight glucose control strategies. The impact on macrovascular complications is still a matter of debate, and so glycaemic control strategies should be placed in the context of multifactorial intervention to address all cardiovascular risk factors. Approaches to achieve glycaemic targets should always ensure patient safety, and results from recent landmark outcome studies support the need for appropriate individualisation of glycaemic targets and of the means to achieve these targets, with the ultimate aim to optimise outcomes and minimise adverse events, such as hypoglycaemia and marked weight gain. The primary goal of the Global Partnership for Effective Diabetes Management is the provision of practical guidance to improve patient outcomes and, in this article, we aim to support healthcare professionals in appropriately tailoring type 2 diabetes treatment to the individual. Patient groups requiring special consideration are identified, including newly diagnosed individuals with type 2 diabetes but no complications, individuals with a history of inadequate glycaemic control, those with a history of cardiovascular disease, children and individuals at risk of hypoglycaemia. Practical guidance specific to each group is provided.

Abstract
Chromosome replication banding studies show that homologous regions on a pair of autosomes generally replicate at the same time in S phase (1). Izumikawa et al. first observed that this was not the case for the imprinted chromosomal region 15q11-q13 (2). This observation has been confirmed in other replication banding studies (3) as well by the fluorescence in situ hybridization (FISH) replication assay (4-9). The latter technique has also been used to observe DNA replication asynchrony in association with allelic inactivation of genes such as those encoding olfactory receptors and the cytokine, interleukin 2 (10,11). The latter genes are not imprinted but display random silencing of an allele in individual cells. In imprinted regions, DNA replication was generally observed to occur earlier on the paternal homologue (5,6,9,12,13). The patterns of allele-specific replication in the cells of Prader- Willi (PWS) and Angelman syndrome (AS) patients, however, have generally been synchronous (5,6,14). Furthermore, an investigation of the kinetics of allele-specific replication timing in the GABRB3/A5 cluster on 15q11-13 revealed that cells from PWS and AS have lost the strict replication timing observed on the parental chromosomes of normal cells (12). These results suggested the requirement of a biparental contribution for the regulation of replication asynchrony and lead to the hypothesis that allelic cross-talk, perhaps via pairing of homologous chromosomes, might play a role in the imprinting process.

Abstract
RESUMO Tetrastichus giffardianus (Hymenoptera: Eulophidae) foi introduzido em 1937 no Estado de São Paulo, Brasil, para o controle biológico da mosca do mediterrâneo, Ceratitis capitata (Diptera: Tephritidae). Apesar de na época este parasitóide ter sido criado em grandes quantidades e liberado em várias fazendas, nunca mais foi relatado no país, levantando controvérsias sobre seu estabelecimento. Este trabalho relata a redescoberta desta espécie no Brasil, mas em locais distantes de onde fora originalmente liberado. Estas novas ocorrências estão na Região Nordeste, onde T. giffardianus parece ter se adaptado melhor do que no território paulista.

Abstract
Infection of human placental syncytiotrophoblast cells with HIV requires direct contact with infected leukocytes. In vitro investigations into mechanisms regulating placental HIV transmission and into the development of therapeutic interventions have been hampered by difficulties inherent in quantitating HIV levels in cocultures of infected lymphocytes and adherent multinucleated syncytiotrophoblast cells. Here, we have used fluorescence in situ hybridization (FISH) for the direct detection of HIV-1 RNA within syncytiotrophoblast cells combined with laser scanning cytometry (LSC) to quantitate HIV levels exclusively in the syncytiotrophoblast cells. HIV-1-infected lymphocytic MOLT-4 cells were cocultured with primary human syncytiotrophoblast cells. Lymphocytic cells were identified with an anti-vimentin antibody and Cy5. HIV RNA was localized by in situ hybridization, using a digoxigenin-labeled riboprobe detected by Oregon Green, and nuclei were stained with 7-aminoactinomycin D. The three-color cocultures were analyzed by LSC to remove unwanted cell populations and quantitate HIV expression levels. The total HIV RNA level (green fluorescence integral) in each colony was normalized for cell size by dividing by the total DNA content (red fluorescence integral). The nuclear-normalized fluorescence integral was 2.3 times higher in infected cocultures than in uninfected cultures. When cocultures were incubated with 10 microM AZT, the green/red fluorescence integral value was significantly lower than that of cocultures incubated in the absence of AZT, corresponding to a 78% reduction in fluorescence. Laser scanning cytometry can be used to quantitate cell-mediated HIV infection in syncytiotrophoblast cells and should allow drug assessment studies and studies aimed at understanding the mechanism of virus entry into trophoblast cells to be carried out.

Abstract
The notion of a small, generic set of chronic illness trajectories that can be independent of specific medical diagnoses, though controversial, has some theoretical, clinical, and qualitative research support. The purpose of this study was to quantitatively describe trajectories among parents of children with a chronic condition. It was hypothesized that factor analysis would confirm 3 trajectories similar to those in the qualitative literature and that parents' perceptions of their child's trajectory would differ significantly from medically based perceptions. A total of 140 parents provided data on their perceptions of the past, present, and future course of the condition of their repeatedly hospitalized child. Fourteen time-related items from the Coping Health Inventory for Parents Questionnaire on Resources and Stress and the Parenting Stress Index were analyzed. Pre- and post-hospitalization factor analyses extracted the same 8 items to construct 3 trajectories: Life Threatening; Declining; and Stable, Optimistic. The views of approximately one third of the parents differed from medically based classifications. Type of nursing care had no bearing on the perceptions of the parents.
