Objective: to develop and validate a mobile application for self-care in sexual and reproductive health for women living with HIV/AIDS. Method: a six-stage methodological study: literature review; content organization; application development; validation by experts; adaptation after validation; validation by the target audience; and adaptation after validation. Health professionals and women living with HIV/AIDS participated. Descriptive statistics, Content Validity Index, were used, considering a minimum agreement value of 0.80 and Gwet’s AC1 test. Results: the application was validated by a multidisciplinary team composed of professionals in gynecology/obstetrics and infectious diseases, yielding a Content Validity Index of 0.93. Additionally, it was validated by the target audience, achieving a score of 0.94. It was well accepted and found to be reliable in validation by experts (AC1 = 0.446; p < 0.001) and by the target audience (AC1 = 0.483; p < 0.001). All professionals pointed out the personal contribution and educational potential of the application. Conclusion: The application represents an essential evidence-based technological tool for strengthening self-care in the sexual and reproductive health of women living with HIV/AIDS. Intervention studies are therefore suggested.

Objective: to compare breastfeeding self-efficacy, parenting behaviors, and adaptation to the maternal role in mothers with planned and unplanned pregnancies during the early postpartum period. Method: a cross-sectional study was conducted with 414 mothers using a convenience sample at a postpartum clinic in a university hospital. Data collection was performed using a form containing sociodemographic and obstetric variables, the Postpartum Parenting Behavior Scale, the Myself as Mother Scale, and the Breastfeeding Self-Efficacy Scale - Short Form. Results: of the 414 mothers included in the study, 163 (39.4%) had unplanned pregnancies. Mothers with unplanned pregnancies had significantly lower breastfeeding self-efficacy, parenting behavior, and maternal role scores than those of mothers with planned pregnancies (p < 0.001). According to regression analysis, unplanned pregnancy is a risk factor that negatively affects mothers’ breastfeeding self-efficacy, parenting behavior, and maternal role (p < 0.001). Conclusion: the self-efficacy in breastfeeding among mothers with unplanned pregnancies was quite low, and their parenting behaviors and maternal roles were quite inadequate. Nurses and midwives should support mothers with unplanned pregnancies in terms of breastfeeding their babies, both during pregnancy and in the early postpartum period, and in adapting to the role of motherhood and raising children.

Objective: this study aims to determine the relationship between climate change worry, premenstrual syndrome severity, and quality of life among women of reproductive age and related factors. Method: this cross-sectional correlational study included women of reproductive age. The sample included 614 women. Data were collected using Descriptive Information Form, Climate Change Worry Scale, Premenstrual Syndrome Scale, SF-12 Quality of Life Scale. Results: a positive correlation was found between the Climate Change Worry Scale and Premenstrual Syndrome Scale, whereas a negative correlation was discovered between the Climate Change Worry Scale and both the physical and mental sub-dimensions of SF-12 Quality of Life Scale (p<0.05). Climate Change Worry Scale, Premenstrual Syndrome Scale and SSF-12 Quality of Life Scale showed statistically significant effects on physical and mental dimension scores (p<0.05). Accordingly, a 1-unit increase in Climate Change Worry Scale score causes a 1.11-unit increase in Premenstrual Syndrome Scale score, a 0.08-unit decrease in physical component score of quality of life scale and a 0.13-unit decrease in mental component score. Conclusion: as climate change worry among women intensifies, the severity of premenstrual syndrome symptoms increases, while their quality of life diminishes. Climate change anxiety, premenstrual syndrom severity, and quality of life were influenced by women’s identifying characteristics.

Objective:  to analyze the clinical-epidemiological profile of pediatric patients receiving extracorporeal membrane oxygenation support at a referral center. Method:  this was a cross-sectional, retrospective study based on the analysis of 108 electronic and physical medical records of pediatric patients from a public hospital. Sociodemographic and clinical data were collected using an instrument developed for this study. For the analysis, absolute and percentage frequencies, measures of central tendency and dispersion, Shapiro-Wilk normality test, Pearson’s chi-square test, logistic regression model with Stepwise input, multiple linear regression analysis, and Durbin-Watson test were used. Results:  of the documents analyzed, 55.5% belonged to female patients. Regarding clinical outcomes, 76.1% were awaiting surgery before cannulation, 69.3% used vasoactive drugs, and 57.4% died. Central venoarterial extracorporeal membrane oxygenation was the most used modality. The main indication for support was low cardiac output syndrome. Patients who developed mechanical complications during extracorporeal membrane oxygenation had a statistically higher risk of death (odds ratio of 2.8). Conclusion:  mechanical complications were associated with an increased risk of mortality. The clinical-epidemiological profile highlights clinical severity, characterized by hemodynamic instability and surgical indication.

Objective:  to investigate the utilization of the Health Care System by women of reproductive age for intrauterine device insertion and to analyze possible inequalities according to sociodemographic characteristics. Method:  cross-sectional study, nested in a prospective cohort, with a random sample of 515 women ≥18 years old, conducted by obstetric nurses at a referral service for intrauterine device insertion. A structured face-to-face questionnaire was applied to obtain information on the use of the healthcare system for intrauterine device insertion. The analysis was based on the Behavioral Model of Health Service Use. Logistic regression and multinomial regression were used to estimate the Odds Ratio of the health care system use according to predisposing factors, race/color, and parity, and facilitating factor, education. Results:  most women are aware of and utilize the system’s health services, especially those with lower levels of education and multiparous women. However, the use of these services to access the intrauterine device is lower, with low access to guidance on reproductive planning and the insertion of the intrauterine device in the services, even lower among those with less education and nulliparous women. Conclusion:  the lower chance of using the health care system to access the intrauterine device among women with less education and nulliparous women reveals social inequalities in access to contraception.

Objective:   to analyze the phenomenon of the infodemic in COVID-19 and its relation with stress, depression, and anxiety in the elderly. Method:  quantitative, correlational, cross-sectional study. Non-probabilistic sample of 195 elderly people, who answered a questionnaire for Infodemic, Perceived Stress Scale, Yesavage Geriatric Depression Scale, and Generalized Anxiety Scale through a telephone and/or online self-administered survey. Before you accept informed consent, descriptive and inferential statistics were used to analyze the data. The Ethics Committee approved the study. Results:  the average age was 69 ± 6.2 years, and 58% were women. The average number of daily hours devoted to information was 5 ± 2.5, higher among men, with no significant differences between the sexes. Hours of infodemic were inversely related to mental health status, and the more hours of infodemic, the lower the level of stress, depression, and anxiety. Conclusion:  the infodemic does not necessarily hurt the mental health of the elderly. From a nursing perspective, it is essential to strengthen critical thinking, promote digital literacy, and support networks and safe spaces that enhance autonomy and confront disinformation.

Objective:  to estimate the incidence of exclusive breastfeeding and weaning in premature infants and identify risk factors after hospital discharge. Method:  prospective cohort study with 237 participants. Factors associated with breastfeeding discontinuation and weaning were analyzed using Poisson regression. Results:  after discharge, 35.3% (95% CI: 29.6-41.8) interrupted breastfeeding and 9.8% (95% CI: 6.5-14.2) weaned. The following factors were associated with breastfeeding cessation: maternal age (RR=0.70; 95% CI: 0.49-0.99); education (elementary school: RR=1.68; 95% CI: 1.00-2.80; high school: RR=1.79; 95% CI: 1.20-2.66); breast stimulation (>6 h: RR=1.88; 95% CI: 1.13-3.13; no stimulation: RR=1.69; 95% CI: 0.98-2.88); hospitalization (RR=1.85; 95% CI: 1.10-3.08); first feeding (>24 h: RR=0.61; 95% CI: 0.38-0.99; did not breastfeed: RR=0.66; 95% CI: 0.43-1.01); and breastfeeding at discharge (RR=3.64; 95% CI: 2.45-5.40). Weaning was associated with not breastfeeding at discharge (RR=3.64; 95% CI: 2.45-5.40). Conclusion:  maternal age, education, hospitalization, and breastfeeding at discharge influenced the interruption of breastfeeding. The absence of breastfeeding at discharge increased the risk of weaning. Early interventions, family support, and policies are essential for maintaining breastfeeding.

Objective:   to analyze the alcohol consumption patterns of adults and older adults before the development of COVID-19 and the influence of alcohol consumption on the outcomes and complications of long COVID. Method:  cross-sectional study based on data from a retrospective cohort conducted with adults and older adult who had COVID-19 and who consumed alcohol before infection with the disease. A standardized electronic form was used to collect sample data and a path model was adjusted to prove the theoretical model on the influence of alcohol consumption on negative outcomes for COVID-19. Results:  sample of 1,171 participants who responded to the question about alcohol. Of these, 408 (34.84%) reported alcohol consumption prior to the disease. The majority were male, younger, highly educated, and had children over the age of 18. The presence of chronic noncommunicable diseases leads to an 11% increase in the chance of hospitalization and a 12% increase in the chance of long COVID. The age of the participants affected alcohol use and directly affected the need for hospitalization. Conclusion:   It is important to adopt intervention strategies aimed at reducing alcohol consumption, especially in contexts of syndemic, to mitigate the associated risks.
