BACKGROUND: Varicella vaccination of non-immune post-partum women is recommended to reduce the risk of chickenpox in mothers and their infants. Though rare, transmission of the varicella vaccine strain vOka can occur from recent vaccinees to non-immune contacts who usually develop mild chickenpox. METHODS/RESULTS: Here we describe an infant hospitalized in the neonatal ICU with vaccine-strain varicella due to transmission from their mother who received the varicella vaccine post-partum. We describe the infection prevention and control strategies implemented to prevent further transmission. CONCLUSION: Vaccine-strain varicella transmission from mother to infant is a rare event and its occurrence in the neonatal ICU setting can be challenging. Anticipatory guidance for mothers vaccinated in the postpartum period and support of parents of an infected infant are recommended.

To examine a wide range of potential contributors to the risk of obesity in female adolescents.Data for this study were collected using a cross-sectional design. A group of 175 female adolescents were recruited, and information on their demographic characteristics, lifestyle-related behaviors, and psychosocial factors was collected using a self-administered questionnaire during September 2018 to January 2019. Data were analyzed using SPSS 24.0.An overestimation of body weight was negatively correlated with overweight in the female adolescents. Age at menarche was negatively correlated with the arisk of overweight. Adolescents who slept for7 h on weekend nights were less likely to be overweight. Eating more cheese, fish, seafood, and organ meats was negatively correlated with obesity risk. The female adolescents were more likely to become overweight if they ate dinners prepared by family and experienced more disturbances from parents and other family members.Female adolescents are a unique population affected by obesity. Although incorporating both lifestyle-related behavioral and psychosocial factors in future investigations and developing multicomponent interventions for obesity prevention are crucial, female adolescents should receive the utmost attention from researchers to alleviate the health burden of obesity.The intertwined nature of obesity-related factors warrants future investigations to elaborate their roles interplaying with the risk of obesity. Multicomponent interventions should be developed, and nurses and health-care providers should target their efforts on obesity prevention for this specific population.

High-fat diet (HFD)-induced obesity results in bone loss associated with an imbalanced gut microbiota and altered immune status.

To understand the prevalence of depressive symptoms among foreign caregivers and the associated factors.A cross-sectional study.Data from 178 Indonesian foreign caregivers, selected based on convenience and snowball sampling in Taiwan, were collected between July 2019 and February 2020 using questionnaires. Stepwise multiple linear regression was used to identify the factors associated with depressive symptoms.Approximately 30.3% of the foreign caregivers displayed depressive symptoms. The symptoms were more prevalent among the participants who were younger; had more social support; shared a bed with others; and experienced higher work-related stress, more loneliness and physical discomfort. The findings suggest that nurses or nurse practitioners visiting patients at home should not only deliver care for them but also show concern for the psychological well-being of the foreign caregivers of these patients. Moreover, interventions should be developed to alleviate or prevent the emergence of depressive symptoms among foreign caregivers.

For patients with locally advanced rectal cancer (LARC), a pathological complete response (pCR) after pre-operative chemoradiotherapy (CRT) does not necessarily indicate a cure. Acellular mucin pools are often seen in patients with pCR. However, the clinical significance of acellular mucin pools in this group of patients remains unknown. This was a retrospective analysis of 225 LARC patients who achieved pCR following CRT and total mesorectal resection from 2011 to 2018. The outcomes of 5-year disease-free survival (DFS), 5-year overall survival (OS) and 5-year distant metastasis-free survival (DMFS) were compared in patients with versus without acellular mucin pools. Among 225 pCR patients, acellular mucin pools could be identified in 56 (24.9%) patients, and recurrence occurred in 30 (13.3%) patients at 5 years. Distant recurrence was seen in 13 (23.2%) patients with acellular mucin pools and in 17 (10.1%) patients without acellular mucin pools. Patients with acellular mucin pools versus those without had poorer DFS (76.8 versus 89.9%, P = 0.010) and OS (87.5 versus 97.0%, P = 0.004) at 5 years. The presence of acellular mucin pools was the independent parameter that remained significant for DFS [hazard ratio (HR) = 3.904; 95% confidence interval (CI) = 1.342-11.356; P = 0.047] and OS (HR = 3.850; 95% CI = 1.214-12.213; P = 0.022) on multivariate analysis. A total of 17 patients demonstrated acellular mucin pools in primary tumour and lymph nodes. Subgroup analysis demonstrated that pCR patients with acellular mucin pools in primary tumour and lymph nodes were more likely to develop distant metastasis compared to pCR patients with acellular mucin pools only in primary tumour (47.1 versus 12.8%, P = 0.005). In summary, acellular mucin pools in LARC patients with pCR after CRT might represent a sign of invasive tumour biology and significantly shorten the prognosis of patients, especially in patients with acellular mucin pools in lymph nodes.

ObjectiveA portable, low-field MRI system is now Food and Drug Administration cleared and has been shown to be safe and useful in adult intensive care unit settings. No neonatal studies have been performed. The objective is to assess our preliminary experience and assess feasibility of using the portable MRI system at the bedside in a neonatal intensive care unit (NICU) at a quaternary children’s hospital.Study designThis was a single-site prospective cohort study in neonates ≥2 kg conducted between October and December 2020. All parents provided informed consent. Neonates underwent portable MRI examination in the NICU with support equipment powered on and attached to the neonate during the examination. A paediatric radiologist interpreted each portable MRI examination. The study outcome variable was percentage of portable MRI examinations completed without artefacts that would hinder diagnosis. Findings were compared between portable MRI examinations and standard of care examinations.ResultsEighteen portable, low-field MRI examinations were performed on 14 neonates with an average age of 29.7 days (range 1–122 days). 94% (17 of 18) of portable MRI examinations were acquired without significant artefact. Significant intracranial pathology was visible on portable MRI, but subtle abnormalities were missed. The examination reads were concordant in 59% (10 of 17) of cases and significant pathology was missed in 12% (2 of 17) of cases.ConclusionThis single-centre series demonstrated portable MRI examinations can be performed safely with standard patient support equipment present in the NICU. These findings demonstrate that portable MRI could be used in the future to guide care in the NICU setting.Trial registration numberNCT04629469.

The photocatalytic water splitting kinetics has been analyzed in this paper. The experimental data are taken from the published works and fitted with different theoretical models. From the results, we find that the photocatalytic kinetics of water splitting can be described by Capelas-Mainardi–Vaz (CMV) model very well. This suggests that the water splitting kinetics can be regarded as a fractional first-order kinetics of the chemical reaction. Also, we notice that photocatalytic water splitting is not always completely a monotone kinetics process.
