In this study, infant vocabulary development was tracked in a multilingual society (Singapore) within a socioeconomically diverse sample. The sample comprised 1316 infants from 17.4 to 27.7 months (669 females, 647 males; 88% Chinese race, 4% Malay, 4% Indian, and 0.004% mixed-race [4% declined to provide race information]). Children varied in English language exposure and socioeconomic status. Analyses focused on identifying demographic predictors of English vocabulary size in multilingually exposed infants. Adaptations of the Macarthur-Bates Communicative Development Inventory for English, Mandarin, and Malay are provided as well as English vocabulary norms that account for variation in English exposure. This manuscript reports the first set of English language norms-calibrated to English exposure-for multilingual infants in a non-Western setting.

To investigate sex-related differences in tic severity, tic-related impairments, and psychiatric comorbidities in childhood.

In this cross-sectional study, tic severity/impairment and demographic factors were collected from 270 children and young people (aged 5-17y, mean 10y 6mo, SD 3y 4mo; 212 males and 58 females) with a tic disorder diagnosis at a specialty clinic. Psychiatric diagnoses and corresponding screening questionnaire scores were collected for attention-deficit/hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), major depressive disorder, and anxiety disorders. Logistic regression was used to compare the effect of sex and age on psychiatric comorbid diagnoses. The Mann-Whitney U test and t-tests were used to assess differences in questionnaire score distribution between sexes.

Females had more severe motor tics (12.55 vs 10.81, p=0.01) and higher global severity scores (38.79 vs 32.66, p=0.03) on the Yale Global Tic Severity Scale. Females were less likely to be diagnosed with ADHD (odds ratio=0.48, 95% confidence interval=0.26-0.89). No significant sex difference was observed in diagnosis rates or symptom severity scores for anxiety or OCD. Females had significantly higher scores than males on the Children's Depression Inventory, Second Edition.

The higher level of motor tic severity and global severity in females further supports the differential natural history of tic disorders in females. Females with tic disorders may be underdiagnosed for ADHD.

This cross-sectional study aimed to examine the associations between parental acculturation level and strategies and children's caries experience and oral health (OH) behaviors.

Participants were immigrant parents of children aged 2-12 years. Data were collected by validated questionnaires gathering information on socio-demographics, child's OH behaviors, and parents'; acculturation and dental examinations determining child's caries experience using DMFT/dmft index. Univariate and multivariate regression analyses were used.

Three hundred and thirty-six parent/child dyads completed the study. Length of residency (B=0.103; 95% CI 0.064, 0.141) parents' education (B=1.691; 95% CI 1.228, 2.155), and household income (B=-0.959; 95% CI -1.566, -0.352) significantly predicted acculturation level. Parents with high Canadian cultural knowledge reported higher frequency of children's toothbrushing (p-value=0.015). Parents of children who consumed sugar >1/day had higher mean scores of acculturation to Canadiancculturated parents. Assimilated parents reported more and marginalized parents reported less favorable OH behaviors than other categories. Parental acculturation level or strategy was not associated with children's caries experience.

Children who do not require oxygen beyond 3 hours after surgery and pass a sleep room air challenge (SRAC) are safe for discharge regardless of polysomnogram (PSG) results or comorbidities.

Cross-sectional prospective study.

All children observed overnight undergoing an adenotonsillectomy for obstructive sleep-disordered breathing were prospectively recruited. Demographic, clinical, and PSG characteristics were stratified by whether the patient had required oxygen beyond 3 hours postoperatively (prolonged oxygen requirement [POR]) and compared using t test, chi-squared test, or Fisher's exact test depending on distribution. Optimal cut points for predicting POR postsurgery were calculated using receiver operating characteristic curves. The primary analysis was performed on the full cohort via logistic regression using POR as the outcome. Significant characteristics were analyzed in a logistic regression model, with significance set at P < .05.

A total of 484 participants met the inclusion criteria. The mean age was 5.65 (standard deviation=4.02) years. Overall, 365 (75%) did not have a POR or any other adverse respiratory event. In multivariable logistic regression, risk factors for POR were an asthma diagnosis (P < .001) and an awake SpO

 <96% (P=.005). The probability of a POR for those without asthma and a SpO

 ≥ 96% was 18% (95% confidence interval 14-22). Age, obesity, and obstructive apnea/hypopnea index were not associated with POR.

In conclusion, all children in our study who are off oxygen within 3 hours of surgery and passed a SRAC were safe for discharge from a respiratory standpoint regardless of age, obesity status, asthma diagnosis, and obstructive apnea/hypopnea index. Additional investigations are necessary to confirm our findings.

3 Laryngoscope, 2021.Various types of hemoglobin (Hb)-based oxygen carriers (HBOCs) have been developed as red blood cell substitutes for treating blood loss when blood is not available. Among those HBOCs, glutaraldehyde polymerized Hbs have attracted significant attention due to their facile synthetic route, and ability to expand the blood volume and deliver oxygen. Hemopure®, Oxyglobin®, and PolyHeme® are the most well-known commercially developed glutaraldehyde polymerized Hbs. Unfortunately, only Oxyglobin® was approved by the FDA for veterinary use in the United States, while Hemopure® and PolyHeme® failed phase III clinical trials due to their ability to extravasate from the blood volume into the tissue space which facilitated nitric oxide scavenging and tissue deposition of iron, which elicited vasoconstriction, hypertension and oxidative tissue injury. Fortunately, conjugation of poly (ethylene glycol) (PEG) on the surface of Hb is capable of reducing the vasoactivity of Hb by creating a hydration layer surrounding the Hbin binding rates than the precursor PolybHb, indicating potentially reduced clearance by CD163 + monocytes and macrophages. Thus, T-state PEG-PolybHb is expected to function as a promising HBOC due to its low oxygen affinity and enhanced stealth properties afforded by the PEG hydration shell.Mild cognitive impairment (MCI) is an early phase of cognitive decline signalling the beginning of severe neurological diseases. Carotid intima-media thickness (cIMT) has shown some correlation with MCI development. This study was conducted to investigate the impact of elevated cIMT on the risk of MCI in adults. A literature search was conducted in PubMed, EMBASE, Cochrane Library, Scopus, Google Scholar and CINAHL databases till 30 July 2021, with keywords ('Carotid Intima-Media Thickness' OR 'cIMT' OR 'IMT' AND 'Cognitive Impairment' OR 'Cognition' OR 'Cognitive Decline' AND 'Mild Cognitive Impairment' OR 'MCI'). Pooled standardized mean difference (SMD)/odds ratio (OR) and 95% confidence interval (CI) were determined for factor-disease association using either fixed (when I2 50%) models. Eight studies involving 1,585 MCI cases and 6,700 normal subjects were included in our meta-analysis which showed no significant association of increased cIMT with the risk of MCI [SMD 1.17, 95% CI -0.09 to 2.42]. However, sensitivity analysis revealed an outlier study significantly affecting the effect size. On omitting the outlier study, the re-evaluated meta-analysis revealed a significant association of cIMT with the risk of MCI [SMD 0.52, 95% CI 0.26 to 0.78]. This significant association was also observed during subgroup analysis in Caucasian population [SMD 0.65, 95% CI 0.13 to 1.18] but not in Asian population [SMD 0.39, 95% CI -0.01 to 0.79]. Elevated cIMT poses a potential risk for MCI. However, more population-based studies are required to corroborate these findings.

This study aimed to investigate the association between Meniere's disease and prior history of asthma.

A nested case-control study.

Among the patients aged ≥40 years from the Korean National Health Insurance Service-Health Screening Cohort 2002-2015, 7,734 diagnosed with Meniere's disease between 2004 and 2015 were enrolled in this study. From the 505,834 participants without a prior history of Meniere's disease, 30,936 control participants were selected based on age, sex, income, and region of residence. The presence of a prior history of asthma before the diagnosis of Meniere's disease was compared between the Meniere's disease group and control group using conditional logistic regression with odds ratios (ORs) and 95% confidence intervals (95% CIs).

Prior history of asthma was associated with 1.30 (1.21-1.39) times higher odds of Meniere's disease (E-value=1.92 [1.71]). Both allergic asthma and nonallergic asthma patients demonstrated higher odds of Meniere's disease than the control group (adjusted OR=1.21 [1.08-1.36] and E-value=1.72 [1.37] for allergic asthma; adjusted OR=1.26 [1.17-1.36] and E-value=1.83 [1.60] for nonallergic asthma).

This study is the first to demonstrate a positive relationship between Meniere's disease and prior asthma history in adults. The association between prior asthma history and Meniere's disease was noted in both allergic and nonallergic asthma cases. The potential development of Meniere's disease should be considered when managing the asthma patients with dizziness or vertigo.

3 Laryngoscope, 2021.The arrangement and type of support has a significant impact on the efficiency of immobilized enzymes. 1-dimensional fibrous materials can be one of the most desirable supports for enzyme immobilization. This is due to their high surface area to volume ratio, internal porosity, ease of handling, and high mechanical stability, all of which allow a higher enzyme loading, release and finally lead to better catalytic efficiency. Fortunately, the enzymes can reside inside individual nanofibers to remain encapsulated and retain their three-dimensional structure. These properties can protect the enzyme's tolerance against harsh conditions such as pH variations and high temperature, and this can probably enhance the enzyme's stability. This review article will discuss the immobilization of enzymes on synthetic polymers, which are fabricated into nanofibers by electrospinning. This technique is rapidly gaining popularity as one of the most practical ways to fibricate polymer, metal oxide, and composite micro or nanofibers. As a result, there is interest in using nanofibers to immobilize enzymes. Furthermore, present research on electrospun nanofibers for enzyme immobilization is primarily limited to the lab scale and industrial scale is still challanging. The primary future research objectives of this paper is to investigate the use of electrospun nanofibers for enzyme immobilization, which includes increasing yield to transfer biological products into commercial applications.
