Deformity Considerations in Cervical Laminoplasty: A Narrative Review.

We discuss the incidence of postoperative kyphosis following laminoplasty and its impact on outcomes, as well as critical radiographic parameters, intraoperative technical factors, and postoperative protocols that can be used to improve results. When appropriately selected, cervical laminoplasty is a motion-sparing treatment option for cervical myelopathy and is a valid alternative to laminectomy and fusion procedures. However, like other posterior-based cervical decompression techniques, laminoplasty can cause postoperative kyphosis. A PubMed search was performed to gather articles that focus on cervical deformity in the context of cervical laminoplasty. The reported conversion rates of lordotic to kyphotic cervical alignment after laminoplasty range from 5.2% to 11.3%. Kyphosis likely reduces the benefit from the operation as measured by postoperative mJOA scores. A surgeon can minimize the risk of causing a clinically significant reduction in lordosis by screening out patients with certain radiographic characteristics. Intraoperative decisions such as dissection techniques, levels chosen, and hybrid constructs can preserve the cervical tension band. Certain postoperative protocols can improve cervical posture. Cervical laminoplasty is an effective tool for treating degenerative cervical myelopathy. Careful radiographic screening, intraoperative decision-making, and postoperative protocols can minimize the development of postoperative cervical deformity and improve outcomes. Level V.

Computational Screening of Putative Catalyst Transition Metal Complexes as Guests in a Ga4L612- Nanocage.

Metal-organic cages form well-defined microenvironments that can enhance the catalytic proficiency of encapsulated transition metal complexes (TMCs). We introduce a screening protocol to efficiently identify TMCs that are promising candidates for encapsulation in the Ga4L612- nanocage. We obtain TMCs from the Cambridge Structural Database with geometric and electronic characteristics amenable to encapsulation and mine the text of associated manuscripts to curate TMCs with documented catalytic functionality. By docking candidate TMCs inside the nanocage cavity and carrying out electronic structure calculations, we identify a subset of successfully optimized candidates (TMC-34) and observe that encapsulated guests occupy an average of 60% of the cavity volume, in line with previous observations. Notably, some guests occupy as much as 72% of the cavity as a result of linker rotation. Encapsulation has a universal effect on the electrostatic potential (ESP), systematically decreasing the ESP at the metal center of each TMC in the TMC-34 data set, while minimally altering TMC metal partial charges. Collectively these observations support geometry-based screening of potential guests and suggest that encapsulation in Ga4L612- cages could electrostatically stabilize diverse cationic or electropositive intermediates. We highlight candidate guests with associated known reactivity and solubility most amenable for encapsulation in experimental follow-up studies.

Preemptive airway management planning: A retrospective evaluation of the pediatric difficult airway consultation service.

The pediatric Difficult Airway Consultation Service (pDACS) was created in 2017 to identify patients with potentially difficult airways and create airway management plans prior to airway management. Consults were either nurse-initiated, physician-initiated, or both nurse-and-physician-initiated and were examined for demographic and clinical factors. If a child had difficult airway risk factors, a consult note with airway management recommendations was completed. We included 419 consults from the 4-year study period for analysis. Sixty-one patients had chronic tracheostomies in place and thus, were analyzed separately. Of the remaining 358 consults, 50% (n = 179) were nurse-initiated, 30.2% (n = 108) physician-initiated, and 19.8% (n = 71) nurse-and-physician-initiated consults. Differences in observed frequency of airway edema (difference, 6.3%; 95%CI 0.1%-12.5%; p = .04), cleft lip/palate (difference, 8.1%; 95%CI 0.07%-16.3%, p = .04), craniofacial abnormalities (difference, 12.3%; 95%CI 1.9%-22.7%, p = .02), and trauma/burn (difference, 6.5%; 95%CI 0.09%-12.8%, p = .04) were calculated. Observed frequencies were higher in physician-initiated compared to nurse-initiated consults. Airway edema was also more prevalent in dual nurse-and-physician-initiated consults (difference, 8.7%; 95%CI 1.6%-15.8%; p = .01). Physician-initiated consults were associated with a greater proportion of high-risk difficult airways than nurse-initiated consults (difference, 26.7%; 95%CI 14.0%-39.4%, p < .001). Approximately 41.9% of patients at high-risk for having a difficult airway were identified by nurse-screening only. Using bag-valve-mask was often the primary ventilation recommendation (89.3%, n = 108) and supraglottic airway placement was the most common tertiary plan (74.2%, n = 83). Direct laryngoscopy (47.1%, n = 65) and videolaryngoscopy (40.6%, n = 56) were the most recommended modes of intubation. Three patients with airway emergencies had previously documented airway management plans and were successfully intubated without complications following the primary intubation technique recommended in their consult note. In our study, nurse-screening identified patients at high-risk for a difficult airway that would likely not have been identified prior to initiation of a screening protocol. Furthermore, airway management plans outlined prior to an emergent difficult airway event may increase first-attempt success at securing the difficult airway, reducing morbidity and mortality.

Molecular detection and identification of Enteromonas species in human and animal hosts using polymerase chain reaction and DNA sequencing

Enteromonas hominis, a human intestinal protozoan parasite of the diplomonad group, has been overlooked because of its commensal features; therefore, molecular studies on this parasite are limited. To address this gap, we designed a molecular screening protocol using polymerase chain reaction (PCR) and DNA sequencing targeting the 18S small subunit ribosomal RNA gene and applied this screening method to the molecular epidemiological analysis of Enteromonas spp. in humans and various livestock. We validated our methodology using stool samples collected from 215 humans and 270 animal hosts (buffaloes, pigs, dogs, goats, horses, rodents, chickens, and ducks) during an annual epidemiological investigation conducted from 2013 to 2016 on Sumba Island, Indonesia. The overall prevalences of Enteromonas spp. were 33.9 % (n = 73/215) in humans and 25.2 % (n = 68/270) in mammals and avians. The positive predictive value of this PCR method for Enteromonas spp., as evaluated through sequencing, was 90.1 % in human samples and 58.1 % in non-human samples (particularly low, 11.4 % in rodents). Although the specificity of the PCR approach may not be perfect, in combination with DNA sequencing, it was effective in detecting and identifying a partial sequence (1458 bp) of the target gene region in Enteromonas species.

Treating Cardiovascular Disease in the Inflammatory Setting of Rheumatoid Arthritis: An Ongoing Challenge.

Despite progress in treating rheumatoid arthritis, this autoimmune disorder confers an increased risk of developing cardiovascular disease (CVD). Widely used screening protocols and current clinical guidelines are inadequate for the early detection of CVD in persons with rheumatoid arthritis. Traditional CVD risk factors alone cannot be applied because they underestimate CVD risk in rheumatoid arthritis, missing the window of opportunity for prompt intervention to decrease morbidity and mortality. The lipid profile is insufficient to assess CVD risk. This review delves into the connection between systemic inflammation in rheumatoid arthritis and the premature onset of CVD. The shared inflammatory and immunologic pathways between the two diseases that result in subclinical atherosclerosis and disrupted cholesterol homeostasis are examined. The treatment armamentarium for rheumatoid arthritis is summarized, with a particular focus on each medication's cardiovascular effect, as well as the mechanism of action, risk-benefit profile, safety, and cost. A clinical approach to CVD screening and treatment for rheumatoid arthritis patients is proposed based on the available evidence. The mortality gap between rheumatoid arthritis and non-rheumatoid arthritis populations due to premature CVD represents an urgent research need in the fields of cardiology and rheumatology. Future research areas, including risk assessment tools and novel immunotherapeutic targets, are highlighted.

Efficacy of transdermal buprenorphine patch for managing withdrawal symptoms in patients with cancer physically dependent on prescription opioids.

The physical dependence on prescription opioids among cancer survivors remains an under-investigated area, with a scarcity of well-designed prospective studies. This single-arm, phase-2 clinical trial in Korea assessed the efficacy and safety of a transdermal buprenorphine patch (TBP) in managing physical dependence on prescription opioids in cancer survivors, as confirmed through the DSM-5 criteria or psychiatric consultation for opioid withdrawal. This study involved a 4-phase treatment protocol of screening, induction/stabilization, discontinuation, and monitoring. The primary outcome was the rate of successful opioid discontinuation, as measured by a negative urine-drug screening at 8 weeks. Key secondary outcomes included the resumption of prescribed opioids, changes in both the Clinical Opioid Withdrawal Scale (COWS) and morphine equivalent daily dose (MEDD), and assessments related to the psychological and physiological aspects of dependence and safety. Thirty-one participants were enrolled. In the intention-to-treat population, the success rate of opioid discontinuation was 58%, with only 2 participants experiencing a resumption of prescribed opioids. Significant reductions were observed in MEDD, which decreased from 98 to 26mg/day (P < .001), and COWS scores, which decreased from 5.5 to 2.8 (P < .001). Desire to use opioids reduced from 7.0 to 3.0 on a 10-point numeric rating scale (P < .001). Toxicities related to TBP were mild and manageable, without severe precipitated withdrawal symptoms. TBP may be considered as an alternative therapeutic option in cancer survivors physically dependent on prescription opioids, especially where sublingual formulations are unavailable.

Suspect screening of per-and polyfluoroalkyl substances in paper by selective and non-selective extraction with UHPLC-Q orbitrap MS

Non-targeted analysis and suspect screening of per- and polyfluoroalkyl substances (PFAS) in various matrices have gained traction with advancements in accurate mass analytical instruments. This study employed ultra-high performance liquid chromatography coupled to quadrupole orbitrap high-resolution mass spectrometry for PFAS suspect screening of paper grades used in the paper recycling chain. The samples were prepared using two extraction techniques; selective accelerated solvent extraction with weak anionic exchange solid-phase extraction and non-selective ultrasonic-assisted extraction. A suspect screening protocol was established to tentatively identify suspected PFAS against spectral databases using a systematic approach of peak filtering and study-specific thresholds for reporting, linked to a confidence level. The possible prevalence of previously unreported PFAS in several paper materials across the various collection sites in the paper recycling chain was inferred by the common detection of short-chain polyfluoroalkyl ketones and diketones in the paper recycling chain. The suspect screening tentatively identified 41 unique PFAS, with 3 common to both pre-treatment techniques. The detection of unique PFAS by the two sample pre-treatment techniques highlighted the significance of both selective and non-selective extraction in PFAS screening endeavours. Further, it showed the importance of understanding the acquisition mechanisms employed in mass spectrometry where data-dependent acquisition triggered fragmentation in certain identified compounds, and not in others. The tentatively identified PFAS indicated that there were several previously unreported PFAS in the paper recycling chain and that additional studies were required to investigate their abundance, possible persistence, bioaccumulation and toxicity, in relation to their functional groups and carbon chains.

Cutting Periprosthetic Infection Rate: Staphylococcus aureus Decolonization as a Mandatory Procedure in Preoperative Knee and Hip Replacement Care-Insights from a Systematic Review and Meta-Analysis of More Than 50,000 Patients.

Background: No consensus in the literature has been found about the necessity of implementing a decolonization screening protocol for Staphylococcus aureus in patients who undergo prosthesis implantation of the knee (TKA) or of the hip (THA), with the aim of reducing periprosthetic infections (PJIs). Methods: A systematic literature search was conducted using PubMed, Web of Science, and Embase in April 2024. Studies conducted on patients who underwent a TKA or THA and who followed a screening and decolonization protocol from S. aureus were included. The benefits of implementing this protocol were evaluated through the number of infections overall caused by S. aureus and other pathogens. The risk of bias and quality of evidence were assessed using Cochrane guidelines. Results: A total of 922 articles were evaluated, and of these, 12 were included in the study for a total of 56,930 patients. The results of the meta-analysis showed a reduced risk of overall PJI (p = 0.002), PJI caused by S. aureus (p < 0.0001), and PJI caused by MRSA (p < 0.0001) and highlighted no differences between the two groups in the onset of a PJI caused by other bacteria (p = 0.50). Conclusions: This study showed that the screening and decolonization of S. aureus in patients undergoing THA or THA procedures reduced the risk of a PJI. The screening and decolonization protocol for this kind of patient represents an important procedure for the safety of the patient and in social-economic and medico-legal terms.

Experiences of Domestic Violence in Adult Patients with Brain Injury: A Select Overview of Screening, Reporting, and Next Steps.

This select overview examines the important intersection of adult domestic violence, including intimate partner violence and elder abuse, with brain injury. Despite the high prevalence of domestic violence amongst brain injury patients, there is a notable gap in screening and management training for providers. To provide optimal patient care, brain injury medicine clinicians must screen, recognize, and treat patients who have experienced domestic violence. This select overview highlights barriers to screening, validated screening tools from other medical disciplines, and management considerations for the brain injury clinician. A suggested protocol for domestic violence screening and management, as well as recommended resources for providers and patients, is summarized.

One-size-fits-all versus risk-category-based screening interval strategies for cardiovascular disease prevention in Chinese adults: a prospective cohort study

In non-high-risk individuals, risk-category-based atherosclerotic cardiovascular disease (ASCVD) screening strategies may be more cost-effective than one-size-fits-all approaches. However, current decisions are constrained by a lack of research evidence. We aimed to explore appropriate risk-category-based screening interval strategies for non-high-risk individuals in ASCVD primary prevention in the Chinese population. We used data from 28,624 participants in the China Kadoorie Biobank (CKB) who had completed at least two field surveys. The risk assessment tools were the 10-year ASCVD risk prediction models developed based on the CKB cohort. We constructed multistate Markov models to model disease progression and estimate transition probabilities between different risk categories. The total person-years spent unidentified in the high-risk state over a 10-year period were calculated for each screening interval protocol. We also estimated the number of ASCVD events prevented, quality-adjusted life years (QALYs) gained, and costs saved when compared to the 3-yearly screening protocol. When compared to the uniform 3-yearly protocol, most risk-category-based screening interval protocols would identify more high-risk individuals timely, thus preventing more ASCVD events and gaining QALYs. A few of them would reduce total health-care costs. The protocol, which used 6-year, 3-year, and 2-year screening intervals for low-risk, intermediate-low-risk, and intermediate-high risk individuals, was optimal, and would reduce the person-years spent unidentified in the high-risk category by 17.9% (95% CI: 13.1%-21.9%), thus preventing an estimated 113 thousand (95% CI: 83-138) hard ASCVD events for Chinese adults aged 30-79 over a 10-year period. When using a lower cost of statin therapy, more screening protocols would gain QALYs while saving costs. For the primary prevention of ASCVD, risk-category-based screening protocols outperformed the one-size-fits-all approach in the Chinese population.

Growth and physical development of children at apparent risk of sarcopenia.

The consequences of sarcopenia on growth have received little attention. We analysed the potential risk resulting from the low lean mass for age expressed through the appendicular lean body mass index (aLBMI) and the ratio aLBM/trunk fat mass (trFM). The sample consisted of 580 participants 10-13 yrs evaluated twice in a 12-month interval: height, trFM, total and aLBM, whole-body bone mineral density less head (WBLH BMD), tibia and radius SOS, maturity and handgrip strength were measured. All variables except maturity and BMI were standardised according to sex and age group (Z-score) using the sample as a reference. A high risk of sarcopenia was identified for Z-scores ≤ -1 on aLBMI (Group B) or aLBM/trFM (Group C), while Z-scores > -1 on both markers were considered at low risk for sarcopenia (Group A). The ANCOVA adjusted for maturity was used to compare the three groups. Girls showed a more significant decrease in the total BMC/LBM ratio in Group B and a minor increase in WBLH BMD in Group C (p < 0.050); boys in Group B showed a tendency to gain less height (p = 0.053). The high risk of sarcopenia expressed through aLBMI or aLBM/trFM Z-score ≤ -1 compromises bone mineralisation in girls. The findings emphasise the necessity of implementing routine screening protocols for sarcopenia risk within clinical environments and educational institutions. Such screenings should extend beyond merely assessing body mass index to encompass broader body composition variables like lean body mass. By integrating these assessments into routine health evaluations, healthcare professionals and educators can proactively identify at-risk individuals and initiate timely interventions for suboptimal physical growth and development.

Perceptions of Smoking Stigma Among African Americans: A Qualitative Study.

African Americans/Blacks (AAB) are at increased risk for morbidity and mortality from smoking-related diseases including lung cancer (LC). Smoking stigma is believed to be a primary barrier to health care-seeking for people who smoke. Previous studies illustrate that perceptions of smoking vary across populations. However, little is known about the prevalence of smoking stigmas among AAB. The purpose of this study was to increase understanding of the perception of cigarette smoking by AAB. We conducted free-listing interviews in which individuals listed all-thoughts and feelings regarding smoking and health-related questions with a convenience sample of eligible AAB adults (n = 58) in the Philadelphia region. Additionally, we collected participant self-reported demographic data. Data were cleaned and the salience of each term was computed using Anthropac. Graphical methods were then used to determine salient responses across groups stratified by gender, age, education, and smoking status. The sample had a median age of 51 years and was 67.2% female. Most participants had completed college (58.6%) and had never smoked (74.1%). Regarding their perceptions of people who smoke cigarettes, results showed that "smelly," "health hazard," and "judgment" were the most salient terms among all-participants. Overall, "smelly" and "unhealthy" were salient for both males and females. However, "dental," "dirty," "addictive," and "habit" were also salient among males. Phrases such as "unhealthy" and "addictive" were primarily salient for older participants (>51 years) versus "smelly" for younger participants. The term "smelly" was salient among all-education levels. However, "unhealthy" was also salient among those with less than a 4-year college degree. Moreover, the terms "smelly" and "annoying" were most common among people who smoke as opposed to "health hazard" among people who don't smoke. We observed that the most stigmatizing language was primarily associated with perceptions of negative social interactions, social judgment, and health-related concerns. Future studies are needed to explore how smoking-related stigmas impact patient adherence to smoking cessation programs and LC screening protocols. Little is known about the prevalence of smoking stigmas among AAB. This study explores the AAB perspective of cigarette smoking and related stigmas. Among AAB, smoking is represented by stigmatizing language across gender, age groups, and smoking history. It is primarily associated with negative social interactions, social judgement, and health-related concerns indicating that smoking stigma is a concern for AAB individuals who smoke. Further research is warranted.

Identification of novel covalent JAK3 inhibitors through consensus scoring virtual screening: integration of common feature pharmacophore and covalent docking.

Accumulated research strongly indicates that Janus kinase 3 (JAK3) is intricately involved in the initiation and advancement of a diverse range of human diseases, underscoring JAK3 as a promising target for therapeutic intervention. However, JAK3 shows significant homology with other JAK family isoforms, posing substantial challenges in the development of JAK3 inhibitors. To address these limitations, one strategy is to design selective covalent JAK3 inhibitors. Therefore, this study introduces a virtual screening approach that combines common feature pharmacophore modeling, covalent docking, and consensus scoring to identify novel inhibitors for JAK3. First, common feature pharmacophore models were constructed based on a selection of representative covalent JAK3 inhibitors. The optimal qualitative pharmacophore model proved highly effective in distinguishing active and inactive compounds. Second, 14 crystal structures of the JAK3-covalent inhibitor complex were chosen for the covalent docking studies. Following validation of the screening performance, 5TTU was identified as the most suitable candidate for screening potential JAK3 inhibitors due to its higher predictive accuracy. Finally, a virtual screening protocol based on consensus scoring was conducted, integrating pharmacophore mapping and covalent docking. This approach resulted in the discovery of multiple compounds with notable potential as effective JAK3 inhibitors. We hope that the developed virtual screening strategy will provide valuable guidance in the discovery of novel covalent JAK3 inhibitors.

Non-participation of asymptomatic candidates in screening protocols reduces early diagnosis and worsens prognosis of colorectal cancer.

The Agatsuma et al's study shows that despite the evidence of the benefits of an early colorectal cancer (CRC) diagnosis, through screening in asymptomatic subjects, up to 50% of candidates reject this option and many of those affected are diagnosed later, in advanced stages. The efficacy of screening programs has been well-established for several years, which reduces the risk of CRC morbidity and mortality, without taking into account the test used for screening, or other tools. Nevertheless, a significant proportion of patients remain unscreened, so understanding the factors involved, as well as the barriers of the population to adherence is the first step to possibly modify the participation rate. These barriers could include a full range of social and political aspects, especially the type of financial provision of each health service. In Japan, health services are universal, and this advantageous situation makes it easier for citizens to access to these services, contributing to the detection of various diseases, including CRC. Interestingly, the symptomatic CRC group had a lower early-stage diagnosis rate than the patients detected during follow-up for other comorbidities, and symptomatic and cancer screening groups showed similar early-stage diagnosis.

Occurrence of Dry Eye Disease in Type 2 Diabetic Patients at a Tertiary Care Center in Maharashtra: A Prevalence Study

Purpose: To evaluate the prevalence and clinical characteristics of dry eye disease (DED) among individuals with type 2 diabetes in a community-based setting. Additionally, the study aimed to identify factors associated with the presence of DED in this population.  Methods: A total of 136 randomly selected patients diagnosed with type 2 diabetes participated in the study, undergoing comprehensive ophthalmic evaluations. These evaluations included corneal sensitivity testing, tear film break-up time (BUT) assessment, the Schirmer I test, and fundus photography. The severity of diabetic retinopathy (DR) was graded according to the International Severity Scale.  Results: Among the 136 subjects, 23 (17.1%) were diagnosed with DED. There were significant associations between DED and higher blood glucose levels (P &lt; 0.001) as well as elevated glycosylated hemoglobin (HbA1c) levels (P &lt; 0.001).  Conclusions: These findings highlight the importance of incorporating dry eye assessments into the routine screening protocol for diabetic patients. The observed prevalence of DED at 17.1% in this cohort is lower than the rates reported in other studies. Importantly, individuals with diabetes who have poorer metabolic control are at a higher risk of developing DED.

Hearing Screening for Older Adults With Cognitive Impairment: A Systematic Review.

: Hearing loss is the largest potentially modifiable risk factor for dementia. Early evaluation and intervention are crucial for older adults with cognitive impairment. However, pure-tone audiometry (PTA), the gold standard, may have limitations. This study reviewed auditory tests for detecting hearing loss in this population, comparing to PTA. Materials and Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review in PubMed, Scopus, and Embase. Ten studies (1,071 participants) comparing auditory tests and PTA in patients with dementia and mild cognitive impairment were included. : Electrophysiological and behavioral tests demonstrated strong correlation and accurate hearing impairment detection compared to PTA. Conversely, self-reported assessment showed weaker correlations when aligned with hearing thresholds. : This study highlights the potential of electrophysiological and behavioral auditory tests in detecting hearing impairment in older adults with cognitive impairment, emphasizing the need for further research to develop practical screening protocols for this vulnerable population.

Rapid Identification of the Spruce Bark Beetle &amp;lt;i&amp;gt;Ips typographus&amp;lt;/i&amp;gt; (Linnaeus) Basing on a New Amplification and Analysis Platform

Insects, one of the major disturbance agents, are regarded as a big challenge to forests. Bark beetles (Coleoptera: Curculionidae: Scolytinae) are among the most destructive pests around the world. The European spruce bark beetle &amp;lt;i&amp;gt;I. typographus &amp;lt;/i&amp;gt;(Linnaeus) is considered the most dangerous species to mature spruce forests throughout Eurasia. In order to improve efficiency, accuracy, and operability of identification, a rapid, simple, highly sensitive and specific screening method is in urgent need. In this study, a rapid classification approach for &amp;lt;i&amp;gt;I. typographus&amp;lt;/i&amp;gt; was established based on the enzyme-mediated duplex exponential amplification (EmDEA) amplification and analysis platform. The method development process consists of target gene selection, primer design, primer screening, and method validation. Parameter analysis demonstrated that this new method has a detection limit of 1.96×103 copies/μL, which is comparable to conventional molecular tools such as PCR. Stable repeatability and high specificity were confirmed by testing 5 samples of &amp;lt;i&amp;gt;I. typographus&amp;lt;/i&amp;gt; and 4 related beetles. Besides, this screening protocol was easy to use, and could be completed in 30 min. With the advantage of isothermal amplification, this method could be further applied in non-laboratory scenarios such as port rapid screening and wild survey. This rapid screening method for &amp;lt;i&amp;gt;I. typographus&amp;lt;/i&amp;gt; is believed to assist precise prediction and efficient prevention of exotic insect species.

Early blood glucose screening in asymptomatic high-risk neonates.

Detecting and treating severe hypoglycemia promptly after birth is crucial due to its association with adverse long-term neurodevelopmental outcomes. However, limited data are available on the optimal timing of glucose screening in asymptomatic high-risk neonates prone to hypoglycemia. Risk factors associated with asymptomatic high-risk neonates include late prematurity≥35 and <37weeks gestation (LPT), small-for-gestational-age (SGA), large-for-gestational-age (LGA), and infant-of-a-diabetic mother (IDM). This study aims to determine the incidence and the impact of individual risk factors on early hypoglycemia (defined as blood glucose≤25 mg/dL in the initial hour after birth) in asymptomatic high-risk neonates. All asymptomatic high-risk neonates ≥35weeks gestation underwent early blood glucose screening within thefirst hour after birth (n=1,690). A 2-year retrospective analysis was conducted to assess the incidence of early neonatal hypoglycemia in this cohort and its association withhypoglycemia risk factors. Out of the 9,919 births, 1,690 neonates (17 %) had risk factors for neonatal hypoglycemia, prompting screening within the first hour after birth. Incidence rates for blood glucose≤25 mg/dL and≤15 mg/dL were 3.1 and 0.89 %, respectively. Of concern, approximately 0.5 % of all asymptomatic at-risk neonates had a blood glucose value of≤10 mg/dL. LPT and LGA were the risk factors significantly associated with early neonatal hypoglycemia. Asymptomatic high-risk neonates, particularly LPT and LGA neonates, may develop early severe neonatal hypoglycemia identified by blood glucose screening in the first hour of life. Additional investigation is necessary to establish protocols for screening and managing asymptomatic high-risk neonates.

Diagnostic value of reversed differential cyanosis in (supra)cardiac total anomalous pulmonary venous return.

To investigate the occurrence of reversed differential cyanosis (RDC) in case of (supra)cardiac total anomalous pulmonary venous return (TAPVR), we explored the hemodynamic changes and oxygen saturation levels during the fetal-to-neonatal transition in (supra)cardiac TAPVR, thereby revealing determinant factors of RDC. A computational model was used to simulate the cardiovascular fetal-to-neonatal transition up to 24 h after birth. Abnormalities associated with TAPVR, like patent ductus arteriosus (PDA) and persistent pulmonary hypertension of the neonate (PPHN), were imposed on the model. Hemodynamic impact on flow distribution and right-sided pressures as well as oxygen saturations were assessed. Model findings demonstrated that RDC in (supra)cardiac TAPVR was dependent on two key factors: (1) the type of pulmonary venous connection being supracardiac or cardiac, and (2) the presence of a patent ductus arteriosus exhibiting right-to-left shunting. Persistence of RDC was mainly determined by the latter; an increase in pulmonary-to-systemic pressure difference by PPHN or PDA-induced pulmonary over-circulation contributed to persistence of RDC. This study highlights the significance of RDC in (supra)cardiac TAPVR and suggests to incorporate early screening ( < 24 h after birth) and to consider RDC as an immediate fail in screening protocols to ensure prompt detection of (supra)cardiac TAPVR. Utilizing a validated computational model for the cardiovascular fetal-to-neonatal transition, this study sheds light on the complex hemodynamics in neonates with (supra)cardiac Total Anomalous Pulmonary Venous Return (TAPVR). Model findings suggest that the often-present pulmonary over-circulation in neonates with TAPVR might significantly contribute to the anomaly's frequent omission during pulse-oximetry screening beyond the first 24 h after birth. This study highlights the diagnostic value of reversed differential cyanosis in early screenings within the first 24 h after birth. By including RDC as an immediate fail in early pulse-oximetry screenings, the likelihood of missing (supra)cardiac TAPVR cases could be reduced.

Universal eye screening: perinatal risk factors and ocular abnormalities in 1795 newborns not meeting retinopathy of prematurity criteria.

This prospective cohort study aimed to investigate the ocular outcomes of universal eye screening in newborns and assess the relationship between different perinatal risk factors and various ocular abnormalities in infants who do not meet the criteria for retinopathy of prematurity (ROP) screening. An universal eye screening questionnaire was utilised to screen newborn babies who did not meet the ROP screening criteria within 72 h of birth at a public and private hospital between June 2016 and April 2018. The questionnaire covered demographic characteristics, neonatal history, and eye examination findings. A trained retina specialist conducted comprehensive anterior and posterior segment examinations utilising a binocular indirect ophthalmoscope. Out of the 1795 newborns screened, 55.2% were male, and 44.8% were female. The most prevalent ocular abnormality observed was retinal haemorrhage (RH), with a prevalence of 10.64% (95% CI: 9.25-12.16%). The prevalence of non-RH abnormality was 7.5% (95% CI: 6.34-8.84%). The retinal haemorrhages were associated with normal vaginal deliveries (OR: 9.91; 95% CI: 6.71-14.64, p-value < 0.001), while non-RH abnormalities were associated with pre-term babies (OR: 4.87; 95% CI: 3.03-7.83, p < 0.001), consanguinity (OR: 2.20; 95% CI: 1.28-3.8, p < 0.001), low birth weight (OR: 0.22; 95% CI: 0.14-0.34, p < 0.001) and systemic abnormalities (OR: 3.08; 95% CI: 1.94-4.91, p < 0.001). Sight-threatening ocular pathology in newborns may be linked to perinatal risk factors such as preterm birth, low birth weight, consanguinity, and systemic abnormalities. Accordingly, it may be prudent to consider specialized ocular screening protocols for neonates within this high-risk cohort in future prospective studies.
