However, in STR analysis, a non-specific peak was detected in the extracted DNA in the presence of skim milk, which was not detected in the presence of BSA, indicating its suitability in forensic analysis. Our study suggests that addition of BSA can efficiently aid the extraction of DNA from forensic evidence mixed with soil.A new label-free method was developed for SERS detection of human apolipoprotein A4. Rolling circle amplification (RCA) was used, which could induce the production of AuNPs (poly adenine and adsorption gold nanoparticles). When there were two DNA labeled antibodies and target protein, MB1 (molecular beacon 1) was unfolded and the substrate was modified in the homogeneous solution, and the proximate complex was formed. The unfolded molecular beacon worked as a primer in the hybridization with the RCA template to start RCA, which could produce many long sequences of DNA containing amounts of adenines. The AuNPs were bound with the long-repeated adenine in the RCA product, causing accumulation of AuNPs on the surface of the electrode. It was indicated that the spectral characteristics of adenine at 736 cm-1 strongly dominated the SERS spectrum of DNA. Adenine worked as an internal marker for detecting human apolipoprotein A4 by using label-free SERS method. When the conditions were optimal, the detection of human apolipoprotein A4 was carried out from 10 pg mL-1 to 1000 ng mL-1, and the detection limit was low (4.1 pg mL-1). Meanwhile, the specificity was also excellent because the antibody could specifically bind with the corresponding antigen. In addition, since adenine was dominant in SERS spectra and the affinity between AuNPs and poly adenine was high, the detection procedure could be performed without any sophisticated modification. This method might provide a promising strategy for diagnosis in clinical practice.

Pediatric primary care redesign includes changes to clinical teams and clinical workflows. This study described the perspectives of pediatric clinicians on their experience with redesign.

This qualitative study explored clinician perspectives on a newborn care redesign pilot at a pediatric primary care site. Newborn Hallway (NBH), implemented in 2019, clustered morning newborn visits with a single physician, increased RN staffing, and provided newborn-specific training for RNs. NBH also revised visit documentation templates to promote communication between RNs and physicians and shared completion of history taking and education. We conducted semi-structured qualitative interviews with clinicians. The interview guide was developed using the Consolidated Framework for Implementation Research. Interviews were recorded and transcribed, and coded using an integrated approach.

We interviewed 17 staff (8 physicians, 8 RNs, 1 nurse practitioner) from 3/2020 to 1/2021. Clinicians reported that NBH implementation was facilitated by widespread agreement on baseline challenges to newborn care, and interest in optimizing roles for RNs. Clinicians believed NBH facilitated teamwork, which mitigated unpredictability in newborn needs and arrival times, and improved staff satisfaction. Perceived barriers to NBH included staffing constraints and ambivalence about whether sharing tasks with RNs would negatively influence patient relationships and continuity.

Pediatric primary care redesign focused on sharing tasks between RNs and physicians can promote teamwork and address unpredictability in clinical settings.

Resolving questions about how redesign influences patient continuity and trust, and clarifying optimal staffing may help facilitate adoption of clinical team and workflow innovations.

There is a paucity of literature evaluating research-funding differences between male and female surgeons. Our study aims to evaluate possible disparities in the National Institutes of Health (NIH) grant awards by surgeon gender, type of medical degree (MD/DO), and advanced degrees among six surgery specialties general surgeons, neurosurgeons, urologists, obstetricians/gynecologists, plastic, and orthopedic surgeons, from 2015 to2020.

A retrospective cohort study was performed investigating the number of NIH grants received by male and female surgeon-scientists overall and within each listed specialty, 2015-2020. As a surrogate for grants submitted, the proportion of active surgeon-scientists per specialty was used. Epacadostat A priori level of significance was defined as P<0.05.

After adjusting for confounders, male surgeons had a higher mean number of NIH grants and higher grant funding than female surgeons (P<0.001 for both). Type of medical degree (MD/DO) was not significantly associated with NIH fundinge studies should further investigate the effects of additional applicant demographics on securing NIH grant funding.

Hepatocellular carcinoma (HCC) is rare among adolescent and young adult (AYA) patients, and resection or transplant remains the only curative therapy. The role of lymph node (LN) sampling is not well-defined. The aim of this study was to describe practice patterns, as well as investigate the impact of LN sampling on survival outcomes in this population.

A retrospective cohort study using the 2004-2018 National Cancer Database (NCDB) was performed. Patients ≤21 y old with nonmetastatic HCC who underwent liver resection or transplant were evaluated. Clinical features of patients who underwent LN sampling were compared to those who did not, and univariable and multivariable logistic regression was performed to evaluate independent predictive factors of node positivity. Survival analysis was performed using Kaplan-Meier methods and Cox Proportional Hazard Survival Regression.

A total of 262 AYA patients with HCC were identified, of whom 137 (52%) underwent LN sampling, 44 patients had positive nodes, 40 (95%) of them had tumors >5cm; 87 (64%) of patients with sampled nodes had fibrolamellar carcinoma (FLC), which was an independent risk factor for predicting positive nodes (P=0.001). There was no difference in overall survival between patients who underwent LN sampling and those who did not; however, 5-y overall survival for node-positive patients was 40% versus 79% for node-negative patients (P<0.0001).

In AYA patients with HCC, LN sampling was not associated with an independent survival benefit. However, FLC was an independent risk factor for LN positivity, suggesting a role for routine LN sampling in these patients.

The value of chest computed tomography (CT) in pediatric primary spontaneous pneumothorax (PSP) remains controversial. This study sought to evaluate the utility of CT scans in a contemporary cohort of children with PSP.

An institutional review board approval was obtained for a retrospective review of all children (aged ≤18y) who underwent video-assisted thoracoscopic surgery (VATS) for PSP between 2009 and 2019 at a university-affiliated pediatric hospital. Preoperative CT scans were evaluated for diagnostic accuracy of the CT of bleb disease.

Thirty nine patients underwent VATS procedures for PSP, 34 (87%) of the patients were noted to have blebs. Twenty eight (72%) patients received preoperative CT scans with a 5.51 male to female ratio. On CT, 17 (61%) were diagnosed with blebs and all had blebs intraoperatively. CT did not identify disease in 11 patients, but seven had blebs intraoperatively. The positive and negative predictive values of preoperative CT for detecting ipsilateral bleb disease were 100% and 36%, respectively, with a sensitivity of 71%. Eleven patients had a contralateral disease on CT (39%). Five received elective contralateral VATS and three developed spontaneous PSP, with intraoperative blebs in all eight patients. Three never developed contralateral PSP. Six (21%) patients with no contralateral disease on CT developed spontaneous PSP with intraoperative blebs.

The decision to operate for PSP should be made based on clinical findings rather than on the presence or absence of blebs identified by CT.

Insomnia in adolescence is common and debilitating yet it remains poorly understood. Here, we examine the complexity of clinical, behavioral, and psychosocial factors characterizing insomnia in adolescents.

Ninety-five adolescents (16-19 years) with (N=47, 31 female) and without (N=48, 28 female) insomnia symptoms participated. In the insomnia group, 26 (20 female) met full DSM-5 criteria for insomnia disorder, while 21 (11 female) met partial criteria. Participants completed a clinical interview and assessments of clinical, behavioral, and psychosocial dimensions associated with insomnia. GLMs and network analyses were used to evaluate group and sex differences in severity and inter-relationships between symptoms.

Adolescents with insomnia symptomatology had lower sleep hygiene and thought control, more depressive symptoms and dysfunctional sleep-related cognitions, and more substance use as a coping behavior than healthy controls. They also indicated higher neuroticism, stress levels, and sleep stresstics of adolescent insomnia, with network analyses revealing a complex interplay between clinical, behavioral, and psychosocial domains. Adolescents with insomnia symptoms, particularly girls, may benefit from interventions to improve negative cognition, mood, and stress, and behavioral strategies to counteract sleep-related maladaptive behaviors.

Young drivers are over-involved in sleepiness-related crashes. The alerting effects of bright light offer a potential countermeasure for driver sleepiness, either replacing or in conjunction with current countermeasures such as the use of caffeine.

Thirty young (18-25) chronically sleep-restricted drivers drove in a simulator under randomized conditions of continuous bright light ('Light,' 500nm, 230μw/cm

), caffeine ('Caffeine,'100mg caffeinated gum), or light and caffeine together ('Light+Caffeine'), after driving under a placebo condition ('Placebo,'decaffeinated gum, 555nm light, 0.3μW/cm

) on three consecutive days. Using mixed-effects linear models, the associations between these conditions and physiological outcomes (EEG alpha and theta power, heart rate, and beat-to-beat intervals), driving performance (lateral lane and steering-related outcomes and lateral acceleration), and subjective sleepiness was assessed.

Relative to Placebo, all conditions improved driving performance outcomes (P<0.0ic community-level mild sleep restriction and provide on-road benefits to reduce severe injuries and fatal sleepiness-related crashes.

The healthcare system aspires to ensure improved access to treatment while working within the existing financial constraints and increasing demands. Patient access schemes (PASs) are initiated to improve access. This study seeks the stakeholders' views on the PAS in the public healthcare sector in Malaysia.

This is an exploratory qualitative study using a web-based online survey and semistructured interviews. The participants were recruited by purposive sampling, where the Ministry of Health of Malaysia staff, pharmaceutical organization personnel, and patient advocacy organization personnel with experience in PAS were invited to participate. A total of 42 consenting participants answered the survey, whereas the face-to-face interview had 8 participants. Interviews were thematically analyzed using the qualitative data analysis software NVivo V.12. The Medical Research and Ethics Committee, Ministry of Health of Malaysia, approved the study.

Only finance-based PAS was reportedly implemented, and it covered drugs for antineoplastic or immunomodulating therapy, alimentary tract and metabolism, sensory organs, and systemic hormonal preparations.
