Background: To investigate the outcomes, clinical prognosticators, and genetic profiles of pediatric left ventricular non-compaction (LVNC).

Methods: All subjects were <18 years old, diagnosed with LVNC between January 2008 and December 2020. Whole-exome sequencing was undertaken. The primary endpoint was composite outcome, including death, heart transplant, and left ventricular assist device implantation.

Results: Thirty-three patients were enrolled, males predominating (57.6%). Median age at diagnosis was 0.33 (0.1-7.2) years. Family history was documented in four (12.1%). Five (15.2%) had sustained arrhythmias. Mean follow-up period was 9.5 years, and 5- and 10-year event-free survival were 84.8% and 66.9%, respectively. Seven died of heart failure, four received heart transplants, and one required left ventricular assist device placement. Log of baseline NT-proBNP (adjusted odds ratio [aOR] = 4.4, p = 0.012) and lack of improvement in NT-proBNP (aOR = 41.2, p = 0.033) impacted the primary outcome most significantly. Eighteen out of 25 genetic testing (72%) revealed chromosomal anomalies, or pathogenic or likely pathogenic variants. Three genetic variants (PLEKHM2 p.G419R, RYR2 p.V2571A, and SCN5A p.M1676I) were significantly associated with the primary outcome (p = 1.52 × 10^-6).

Conclusions: Pediatric LVNC is a rare disorder with variable genetic underpinnings. Baseline NT-proBNP values and lack of improvement in NT-proBNP levels were important predictors of poor long-term outcomes. Pathogenic genetic variants or chromosomal anomalies are not unusual.

Background/purpose: Introducing complementary foods to infants is a critical stage in their healthy growth and development process. In this study, we analyzed the feeding habits and choices of caregivers in Taiwan during this essential transition period.

Methods: Data from the 2013-2016 Nutrition and Health Survey in Taiwan were analyzed. Using a multistage stratified sampling technique, we collected data through questionnaires on the feeding practices, challenges, and information sources associated with complementary feeding. We also investigated the timing of introducing various foods. Certain feeding indicators recommended by the World Health Organization were modified and used for analysis.

Results: Among 439 caregivers of infants aged 2-24 months, complementary feeding typically began at 5 months, and it primarily began with cereals and pureed foods. At 6-8 months of age, 98.29% of the infants received these foods. Only 48.39% of infants aged 6-24 months consumed eggs or flesh foods. Among the primary challenges for caregivers were concerns regarding infants' adaptation to new foods (38.2%), refusal of foods by infants (37.1%), and uncertainty regarding which foods to introduce (11.4%). The main sources of information were friends and family (46.9%), the Internet (46.5%), and baby care books (35.6%). Notably, approximately 51% of the respondents used commercial baby foods.

Conclusion: In Taiwan, although the majority of infants begin complementary feeding on time, the introduction of eggs and flesh foods is typically delayed. Given the growing reliance on the Internet in the modern age, accurate feeding information should be disseminated online.

Background: Enterovirus is a common pediatric infectious disease, but the epidemiological data in young infants were lacking. This study aims to evaluate the role of enterovirus in febrile young infants and identify risk factors for severe infections.

Methods: We enrolled febrile infants younger than 90 days admitted to National Taiwan University Hospital from January 2010 to June 2021. Enterovirus infection was confirmed via viral isolation or pan-enterovirus PCR. Central nervous system involvement was defined by positive culture or PCR in cerebrospinal fluid. Severe complications included sepsis, hepatic failure, myocarditis, shock, encephalitis, acute kidney injury, respiratory failure, and multiorgan failure.

Results: Out of 840 febrile infants, 17.4% (n = 146) had enterovirus infection. Among these, 46% (n = 67) presented with meningitis and/or encephalitis. Early-onset enterovirus infection within the first two weeks of life was significantly linked to increased risks of anemia (hemoglobin <9 g/dL), ICU admission, central nervous system involvement, shock, hepatic failure, and mortality. Multivariable logistic regression identified high-risk serotypes (aOR 17.4, [95% CI 1.58, 191.5], p = 0.019) and hemoglobin <9 g/dL (aOR 44.9, [95% CI 5.6, 357.6], p < 0.001) as significant risk factors for severe complications.

Conclusions: Enterovirus accounted for 17.4% of the etiology in febrile young infants and the case-fatality rate was 2%. Febrile young infants who had risk factors of enterovirus infection should consider viral culture or PCR examination for confirmation.

To achieve a consensus on optimal blood pressure (BP) targets for older adults remains challenging, necessitating a trade-off between cardiovascular benefits and the risk of impaired organ perfusion. Evidence suggests that age and frailty have a minimal influence on the cardiovascular benefits of intensive BP control in community-dwelling elderly. Nonetheless, an increased incidence of acute kidney injury with intensive BP control has been observed in octogenarians. Therefore, it is recommended to maintain systolic BP below 130 mmHg for hypertensive patients aged 65-80 years. If well-tolerated, a systolic BP target below 120 mmHg can be recommended for patients with chronic kidney disease (CKD). However, no conclusive evidence supports a stringent BP target for patients aged 80 years and older. The selection of antihypertensive medications for elderly patients requires consideration of their cardiovascular condition and potential contraindications. Combination therapy may be necessary to achieve the desired BP target. Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers are the primary choices for patients with CKD. Newer generation mineralocorticoid receptor antagonists may further reduce the risk of cardiovascular or renal events in this population. In conclusion, managing hypertension in elderly patients requires a personalized approach that balances cardiovascular benefits with potential risks, considering individual health profiles and tolerability.
