Laser-Based Length-Measuring Board for the Measurement of Infant Body Length from Outside an Incubator
The proposed validated laser-based length-measuring board offers a suitable alternative to conventional length-measuring boards for contactless measurement of infant body length
Job insecurity and mental health among community workers
This paper explores the mediating role of work-family conflict (WFC) in the relationship between job insecurity and mental health. Based on the Job Demands-Resources (JD-R) model and the Conservation of Resources (COR) Theory, a conceptual model is developed and tested. An online survey was created, including a sociodemographic questionnaire and measures of job insecurity, WFC, and mental health. Participants were 189 community social workers act…
Can virtuality be protective of team trust? Conflict and effectiveness in hybrid teams
Virtuality is noticeably present in organisations and influences the way people interact within teams. This study involved 104 organisational teams with some degree of virtuality and intends to analyze a moderated-mediation model in which virtuality moderates the indirect effect of team conflict on team effectiveness and innovation through team trust. First, results reveal that the negative association between conflict and team trust was signific…
Innovation in Teams
The main purpose of the present research was to analyze the relationship between team psychological capital and innovation, considering team learning as a mediating variable. A field survey was carried out, which included 124 work teams belonging to organizations from different sectors of activity. Hypotheses were tested through PROCESS. Results supported a direct positive relationship between team psychological capital and team innovation and an…
Antenatal screenings and maternal diagnosis among pregnant women in Sao Tome & Principe—Missed opportunities to improve neonatal health
Newborn mortality and adverse birth outcomes (ABOs) in Sao Tome & Príncipe (STP) are overwhelmingly high, and access to quality-antenatal care (ANC) is one of the strategies to tackle it. This study aimed to fill the gaps in ANC screenings with a focus on how to improve neonatal outcomes. We conducted a retrospective hospital-based study in which ANC pregnancy cards were reviewed. Screenings were described and compared according to the total numb…
The Lockdown Impact on the Relations between Portuguese Parents and Their 1- to 3-Year-Old Children during the Covid-19 Pandemic
Many countries have applied mandatory confinement measures in response to the COVID-19 pandemic, such as school and kindergarten closures, which confined families to their homes. The study concerns the impacts of the first COVID-19 lockdown on the relationships between Portuguese parents and their children, in a non-clinical population composed of fathers and mothers of children between the ages of 12 months and 3 years and 364 days. An online qu…
Comparison of Growth Curve Estimates of Infants in São Tomé Island, Africa, with the WHO Growth Standards
This birth cohort study compared the infant growth curve estimates in São Tomé Island to the WHO growth standards. Despite this island belonging to a lower-middle-income country, there were several factors favorable for growth that were present. Four-hundred and seventy-five full-term singleton appropriate for-gestational-age infants were enrolled and followed-up to 24 months of age. Weight-for-age, length-for-age, weight-for-length, body mass in…
Subclinical Enteric Parasitic Infections and Growth Faltering in Infants in São Tomé, Africa
The associations between enteric pathogenic parasites and growth in infants in São Tomé were explored using a refined anthropometric approach to recognize early growth faltering. A birth cohort study was conducted with follow-up to 24 months of age. Microscopic examination for protozoa and soil-transmitted helminths was performed. Anthropometric assessments included: z-scores for weight-for-length (WLZ), length-for-age (LAZ), weight (WAVZ) and le…
The effects of violence on infants and young children
Multiple factors contribute to violence, and only a multidisciplinary approach can be used to deal with this situation. Strategic errors committed by governments, such as not giving priority to basic health care or education, and foreign obligations producing severe economic recession, cause the people, especially children, to be subjected to political and social violence. Poverty and its associated risks are linked to violence. However, not all …
