The lateral flow immunoassay (LFIA) technique is largely employed for the point-of-care detection of antibodies especially for revealing the immune response in serum. Visual LFIAs usually provide the qualitative yes/no detection of antibodies, while quantification requires some equipment, making the assay more expensive and complicated. To achieve visual semi-quantification, the alignment of several lines (made of the same antigen) along a LFIA strip has been proposed. The numbering of the reacting lines has been used to correlate with the quantity of some biomarkers in serum. Here, we designed the first semiquantitative LFIA for detecting antibodies and applied it to classify the immune response to SARS-CoV-2 raised by vaccination or natural infection. We used a recombinant spike receptor-binding domain (RBD) as the specific capture reagent to draw two test lines. The detection reagent was selected among three possible ligands that are able to bind to anti-spike human antibodies: the same RBD, staphylococcal protein A, and anti-human immunoglobulin G antibodies. The most convenient detector, adsorbed on gold nanoparticles, was chosen based on the highest correlation with an antibody titre of 171 human sera, measured by a reference serological method, and was the RBD (Spearman's rho = 0.84). Incorporated into the semiquantitative LFIA, it confirmed the ability to discriminate high- and low-titre samples and to classify them into two classes (Dunn's test, P < 0.05). The proposed approach enabled the semiquantification of the immune response to SARS-CoV-2 by the unaided eye observation, thus overcoming the requirement of costly and complicated equipment, and represents a general strategy for the development of semiquantitative serological LFIAs.

Background: Affective neuroscience (AN) theory assumes the existence of seven basic emotional systems (i.e., SEEKING, ANGER, FEAR, CARE, LUST, SADNESS, PLAY) that are common to all mammals and evolutionarily determined to be tools for survival and, in general, for fitness. Based on the AN approach, the Affective Neuroscience Personality Scales (ANPS) questionnaire was developed to examine individual differences in the defined basic emotional systems. The current systematic review aims to examine the use of ANPS in clinical contexts attempting to define those behavioral elements associated with underlying stable personality traits., Methods: The systematic review was conducted following the PRISMA statements. PubMed and PsycInfo were used for research literature from March 2003 to November 2021., Results: Forty-four studies including ANPS were identified from 1763 studies reviewed. Sixteen studies met the inclusion criteria., Limitations: The review comprised some papers with incomplete psychological assessments (e.g., lack of other measures in addition to the ANPS) and missing information (e.g., on the [sub]samples), which may affect the generalizability of findings., Conclusion: Specific endophenotypes and/or patterns of emotional/motivational systems were found for several mental disorders. Specifically, endophenotypes emerged for the Depressive and Autism Spectrum Disorders, Borderline and Avoidant Personality Disorders, type I and II Bipolar Disorders, and the Obsessive-Compulsive Disorder. The endophenotypes can provide useful reflective elements for both psychodiagnosis and intervention. Overall, the current study may represent an attempt to contribute to the understanding of the basic emotional systems involved in the psychopathological manifestations identified by AN., Competing Interests: Declaration of competing interest The authors declare no potential conflict of interest., (Copyright © 2022 Elsevier B.V.

Introduction: Autologous and heterologous assisted reproductive technology (ART) conceptions have been on the rise for the last few decades and alongside with that have the rate of multiple pregnancies. Multiple gestations are associated with high odds of gestational complications and, in turn, adverse delivery and feto-neonatal outcomes. Whether ART-conception further increases such elevated risk is still debated. ART is more commonly accessed by older women with chronic diseases, which relate to heightened likelihood of complications. We decided to investigate the influence of autologous and heterologous ART conception compared to spontaneous conception on delivery and feto-neonatal outcomes of diamniotic twin pregnancies in a cohort of healthy women with no chronic conditions or gestational complications. Materials and methods: Retrospective cohort study among diamniotic twin pregnancies in mothers without pregestational or gestational disease. Delivery and feto-neonatal outcomes were compared among three groups according to mode of conception: (1) spontaneous conception (SC, referent group, n  = 251 pregnancies), (2) autologous ART-conception (A-ART, n  = 87), and (3) heterologous ART-conception (H-ART, n  = 22). Results: At adjusted analyses, twin pregnancies conceived by A-ART showed a twofold heightened risk of delivery by urgent/emergent cesarean section, as well as four and sevenfold increase in odds of blood loss >1000 and >1500 mL, respectively. H-ART pregnancies were at fivefold higher risk of undergoing prelabor cesarean section compared to SC, whereas no differences were identified for odds of severe post-partum hemorrhage. Also, A-ART and H-ART gestations displayed fetal and neonatal outcomes similar to SC pregnancies when analysis was adjusted for relevant confounding factors. Conclusion: Our results suggest that both A-ART and H-ART conception associate with increased odds of operative delivery among diamniotic twin pregnancies in healthy mothers with no chronic diseases or gestational complications. Also, a higher risk of severe postpartum hemorrhage appears to relate to A-ART independent of mode of delivery and maternal age. Further studies with larger series of uncomplicated twin pregnancies are warranted to improve our understanding of the relationship of ART to adverse delivery outcomes.

Objective: Optimal management of twin deliveries is controversial. We aimed to assess if intertwin delivery interval, after vaginal delivery of the first twin, may have an influence on adverse neonatal outcomes of the second twin Study design: This is a retrospective observational study including diamniotic twin pregnancies with vaginal delivery of the first twin, between January 2000 and July 2017. Inclusion criteria were diamniotic pregnancies and vaginal delivery of the first twin. We excluded higher twin order, monoamniotic pregnancies, cesarean delivery of the first twin and patients with missing data. Results: A number of 400 diamniotic twin pregnancies met the inclusion criteria and were divided, considering intertwin delivery interval into (1) ≤30 minutes ( n  = 365); and (2) >30 minutes ( n  = 35). Considering the two study groups, maternal and first twin characteristics and outcomes were similar. Second twin reported higher incidence of cesarean section and vacuum delivery, but similar incidence of neonatal adverse outcomes, in case of intertwin interval >30 minutes. At multivariate analysis, a difference between second and first twin weight ≥25% was correlated to neonatal adverse outcome, while we did not found this correlation with a cut-off of 30 minutes. Conclusions: In our study, growth discrepancy between twins was significantly correlated to adverse neonatal outcomes, while intertwin delivery time was not an influencing factor. So, in line with this result, in our clinical practice, we do not use a fixed time in which both twins should be delivered, neither in monochorionic nor in dichorionic pregnancies, when fetal wellbeing was demonstrated during labor.

The Authors report a case of athelia and amastia observed in a 28-year-old woman. The association of severe dental alterations, nail dystrophies and irregular cutaneous hyperpigmentation with normal sweating, make it possible to catalogue the anomaly in the hydrotic ectodermal dysplasia, an autosomal dominant hereditary disease. The syndrome, transmitted by the father, is also present in two brothers of the patient: the association of sphincter urethrae agenesis, responsible for urinary incontinence unsuccessful treated with two surgical operations, is to be considered quite fortuitous.

Unlabelled: All bronchoscopies in our institution are performed by physician-respiratory therapist teams. The therapist instructs the patient, anesthetizes him, does the biopsies, and prepares specimens for laboratory testing., Methods: We undertook a retrospective study of our performance to evaluate the safety, yield, and cost of this system., Results: Of 216 procedures evaluated, therapist-performed biopsies provided a specific diagnosis in 55%. When a tumor-like mass was seen directly, biopsies were positive 95.7% of the time. No procedure was associated with death. Complications included fever in about 9%, hoarseness in 2%, hemoptysis in 1%, and pneumothorax in one procedure (0.5%). Our institutional costs for flexible fiberoptic bronchoscopy by a physician-respiratory therapist team were only 34% of what they would have been if the same procedures had been performed in the operating room. RESULTS performed were comparable to all others reported in the literature., Conclusion: This study clearly demonstrates that respiratory therapists can provide high quality, low cost, safe bronchoscopic assistance to pulmonary internists.

A 51-yr-old asthmatic carpenter aspirated a penny using a hand-held, self-pressurized aerosol device. The penny was extracted using a fiberoptic bronchoscope. Because no similar instances are reported in the medical literature, experimental systems were designed to test the likelihood of this event happening with a variety of nebulizers. Nickels , dimes , and pennies were tested for ejection potential and for aspiration likelihood. All inhalers, excepting that designed for Intal, were capable of accommodating dimes and pennies and ejecting them down simulated airways during inspiration. Nickels were accommodated by several inhalers but were not ejected during conventional inspiratory volumes and pressures.
