Abstract
OBJECTIVES To estimate excess health care costs in the 12 months following COVID-19 diagnosis. STUDY DESIGN Retrospective cohort study using Blue Cross Blue Shield of Rhode Island claims incurred from January 1, 2019, to March 31, 2022, among commercial and Medicare Advantage members. METHODS Difference-in-differences analyses were used to compare changes in health care spend between the 12 months before (baseline period) and the 12 months after (post period) COVID-19 diagnosis for COVID-19 cases and contemporaneous matched controls without COVID-19. RESULTS Overall, there were 7224 commercial and 1630 Medicare Advantage members with a COVID-19 diagnosis on/before March 31, 2021, each with a matched control, yielding a sample of 14,448 commercial and 3260 Medicare Advantage members. Among commercial members, 51.9% were aged 25 to 54 years and 54.0% were female. Among Medicare Advantage members, 94.2% were 65 years or older and 62.0% were female. Among commercial members, from the baseline period to the post period, total health care spend increased $41.61 (7.7%) per member per month (PMPM) more among COVID-19 cases compared with their matched controls. Among Medicare Advantage members, the difference-in-differences was greater, with spend increasing $97.30 (13.1%) PMPM more among cases compared with controls. The difference-in-differences was greatest for outpatient and professional services (both populations) and prescription services (Medicare Advantage only). CONCLUSIONS COVID-19 diagnosis was associated with excess health care spend PMPM over the subsequent 12 months, highlighting the importance of societal preparations to support individuals' long-term health care needs following COVID-19 and as a part of future pandemic preparedness.

Abstract
Marine historical ecology provides a means to establish baselines to inform current fisheries management. Groupers (Epinephelidae) are key species for fisheries in the Mediterranean, which have been heavily overfished. Species abundance and distribution prior to the 20th century in the Mediterranean remains poorly known. To reconstruct the past biogeography of Mediterranean groupers, we investigated whether Zooarchaeology by Mass Spectrometry (ZooMS) can be used for identifying intra-genus grouper bones to species level. We discovered 22 novel, species-specific ZooMS biomarkers for groupers. Applying these biomarkers to Kinet Höyük, a Mediterranean archaeological site, demonstrated 4000 years of regional Epinephelus aeneus dominance and resiliency through millennia of fishing pressures, habitat degradation and climatic changes. Combining ZooMS identifications with catch size reconstructions revealed the Epinephelus aeneus capacity for growing 30 cm larger than hitherto documented, revising the maximum Total Length from 120 to 150 cm. Our results provide ecological baselines for a key Mediterranean fishery which could be leveraged to define and assess conservation targets.

Abstract
Synthetic self-propelled nano and microparticles have a growing appeal for targeted drug delivery, collective functionality, and manipulation at the nanoscale. However, it is challenging to control their positions and orientations under confinement, e.g., in microchannels, nozzles, and microcapillaries. This study reports on the synergistic effect of acoustic and flow-induced focusing in microfluidic nozzles. In a microchannel with a nozzle, the balance between the acoustophoretic forces and the fluid drag due to streaming flows generated by the acoustic field controls the microparticle's dynamics. This study manipulates the positions and orientations of dispersed particles and dense clusters inside the channel at a fixed frequency by tuning the acoustic intensity. The main findings are: first, this study successfully manipulates the positions and orientations of individual particles and dense clusters inside the channel at a fixed frequency by tuning the acoustic intensity. Second, when an external flow is applied, the acoustic field separates and selectively extrudes shape-anisotropic passive particles and self-propelled active nanorods. Finally, the observed phenomena are explained by multiphysics finite-element modeling. The results shed light on the control and extrusion of active particles in confined geometries and enable applications for acoustic cargo (e.g., drug) delivery, particle injection, and additive manufacturing via printed self-propelled active particles.

Abstract
Taxonomic identification of whale bones found during archaeological excavations is problematic due to their typically fragmented state. This difficulty limits understanding of both the past spatio-temporal distributions of whale populations and of possible early whaling activities. To overcome this challenge, we performed zooarchaeology by mass spectrometry on an unprecedented 719 archaeological and palaeontological specimens of probable whale bone from Atlantic European contexts, predominantly dating from ca 3500 BCE to the eighteenth century CE. The results show high numbers of Balaenidae (many probably North Atlantic right whale (Eubalaena glacialis)) and grey whale (Eschrichtius robustus) specimens, two taxa no longer present in the eastern North Atlantic. This discovery matches expectations regarding the past utilization of North Atlantic right whales, but was unanticipated for grey whales, which have hitherto rarely been identified in the European zooarchaeological record. Many of these specimens derive from contexts associated with mediaeval cultures frequently linked to whaling: the Basques, northern Spaniards, Normans, Flemish, Frisians, Anglo-Saxons and Scandinavians. This association raises the likelihood that early whaling impacted these taxa, contributing to their extirpation and extinction. Much lower numbers of other large cetacean taxa were identified, suggesting that what are now the most depleted whales were once those most frequently used.

Abstract
In 2018, a well-constructed cist-type grave was discovered at Ba`ja, a Neolithic village (7,400-6,800 BCE) in Southern Jordan. Underneath multiple grave layers, an 8-year-old child was buried in a fetal position. Over 2,500 beads were found on the chest and neck, along with a double perforated stone pendant and a delicately engraved mother-of-pearl ring discovered among the concentration of beads. The first was found behind the neck, and the second on the chest. The meticulous documentation of the bead distribution indicated that the assemblage was a composite ornament that had gradually collapsed, partly due to the burying position. Our aim was to challenge time degradation and to reimagine the initial composition in order to best explore the significance of this symbolic category of material culture, not as mere group of beads, but as an ornamental creation with further aesthetic, artisanal and socioeconomic implications. The reconstruction results exceeded our expectations as it revealed an imposing multi-row necklace of complex structure and attractive design. Through multiple lines of evidence, we suggest that the necklace was created at Ba`ja, although significant parts of beads were made from exotic shells and stones, including fossil amber, an unprecedented material never attested before for this period. The retrieval of such an ornament from life and its attribution to a young dead child highlights the significant social status of this individual. Beyond the symbolic functions related to identity, the necklace is believed to have played a key role in performing the inhumation rituals, understood as a public event gathering families, relatives, and people from other villages. In this sense, the necklace is not seen as belonging completely to the realm of death but rather to the world of the living, materializing a collective memory and shared moments of emotions and social cohesion.

Abstract
The Neolithic burial of Grotta di Pietra Sant'Angelo (CS) represents a unique archaeological finding for the prehistory of Southern Italy. The unusual placement of the inhumation at a rather high altitude and far from inhabited areas, the lack of funerary equipment and the prone deposition of the body find limited similarities in coeval Italian sites. These elements have prompted wider questions on mortuary customs during the prehistory of Southern Italy. This atypical case requires an interdisciplinary approach aimed to build an integrated bioarchaeological profile of the individual. The paleopathological investigation of the skeletal remains revealed the presence of numerous markers that could be associated with craft activities, suggesting possible interpretations of the individual's lifestyle. CT analyses, carried out on the maxillary bones, showed the presence of a peculiar type of dental wear, but also a good density of the bone matrix. Biomolecular and micromorphological analyses of dental calculus highlight the presence of a rich Neolithic-like oral microbiome, the composition of which is consistent with the presence pathologies. Finally, paleogenomic data obtained from the individual were compared with ancient and modern Mediterranean populations, including unpublished high-resolution genome-wide data for 20 modern inhabitants of the nearby village of San Lorenzo Bellizzi, which provided interesting insights into the biodemographic landscape of the Neolithic in Southern Italy.

Abstract
Bacterial RNP bodies (BR-bodies) are non-membrane-bound structures that facilitate mRNA decay by concentrating mRNA substrates with RNase E and the associated RNA degradosome machinery. However, the full complement of proteins enriched in BR-bodies has not been defined. Here we define the protein components of BR-bodies through enrichment of the bodies followed by mass spectrometry-based proteomic analysis. We found 111 BR-body enriched proteins, including several RNA binding proteins, many of which are also recruited directly to in vitro reconstituted RNase E droplets, showing BR-bodies are more complex than previously assumed. While most BR-body enriched proteins that were tested cannot phase separate, we identified five that undergo RNA-dependent phase separation in vitro, showing other RNP condensates interface with BR-bodies. RNA degradosome protein clients are recruited more strongly to RNase E droplets than droplets of other RNP condensates, implying that client specificity is largely achieved through direct protein-protein interactions. We observe that some RNP condensates assemble with preferred directionally, suggesting that RNA may be trafficked through RNP condensates in an ordered manner to facilitate mRNA processing/decay, and that some BR-body associated proteins have the capacity to dissolve the condensate. Finally, we find that RNA dramatically stimulates the rate of RNase E phase separation in vitro, explaining the dissolution of BR-bodies after cellular mRNA depletion observed previously. Altogether, these results suggest that a complex network of protein-protein and protein-RNA interactions controls BR-body phase separation and RNA processing.

Adaptation to extreme weather events often occurs in response to an event, with communities learning fast following unexpectedly impactful events. Using extreme value statistics, here we show where regional temperature records are statistically likely to be exceeded, and therefore communities might be more at-risk. In 31% of regions examined, the observed daily maximum temperature record is exceptional. Climate models suggest that similar behaviour can occur in any region. In some regions, such as Afghanistan and parts of Central America, this is a particular problem - not only have they the potential for far more extreme heatwaves than experienced, but their population is growing and increasingly exposed because of limited healthcare and energy resources. We urge policy makers in vulnerable regions to consider if heat action plans are sufficient for what might come.

Abstract
As of March 7, 2023, a total of 30,235 confirmed and probable monkeypox (mpox) cases were reported in the United States,† predominantly among cisgender men§ who reported recent sexual contact with another man (1). Although most mpox cases during the current outbreak have been self-limited, cases of severe illness and death have been reported (2-4). During May 10, 2022-March 7, 2023, 38 deaths among persons with probable or confirmed mpox¶ (1.3 per 1,000 mpox cases) were reported to CDC and classified as mpox-associated (i.e., mpox was listed as a contributing or causal factor). Among the 38 mpox-associated deaths, 94.7% occurred in cisgender men (median age = 34 years); 86.8% occurred in non-Hispanic Black or African American (Black) persons. The median interval from symptom onset to death was 68 days (IQR = 50-86 days). Among 33 decedents with available information, 93.9% were immunocompromised because of HIV. Public health actions to prevent mpox deaths include integrated testing, diagnosis, and early treatment for mpox and HIV, and ensuring equitable access to both mpox and HIV prevention and treatment, such as antiretroviral therapy (ART) (5).

Abstract
RATIONALE Dental calculus (mineralised dental plaque) is composed primarily of hydroxyapatite. We hypothesise that the carbonate component of dental calculus will reflect the isotopic composition of ingested simple carbohydrates. Therefore, dental calculus carbonates may be an indicator for sugar consumption, and an alternative to bone carbonate in isotopic palaeodiet studies. METHODS We utilised Fourier transform infrared attenuated total reflectance analysis to characterise the composition and crystallisation of bone and dental calculus before isotope analysis of carbonate. Using a Sercon 20-22 mass spectrometer coupled with a Sercon GSL sample preparation system and an IsoPrime 100 dual inlet mass spectrometer plus Multiprep device to measure carbon, we tested the potential of dental calculus carbonate to identify C4 resources in diet through analysis of δ13 C values in paired bone, calculus and teeth mineral samples. RESULTS The modern population shows higher δ13 C values in all three tissue carbonates compared to both archaeological populations. Clear differences in dental calculus δ13 C values are observed between the modern and archaeological individuals suggesting potential for utilising dental calculus in isotope palaeodiet studies. The offset between dental calculus and either bone or enamel carbonate δ13 C values is large and consistent in direction, with no consistent offset between the δ13 C values for the three tissues per individual. CONCLUSIONS Our results support dental calculus carbonate as a new biomaterial to identify C4 sugar through isotope analysis. Greater carbon fractionation in the mouth is likely due to the complex formation of dental calculus as a mineralized biofilm, which results in consistently high δ13 C values compared to bone and enamel.

Abstract
Embryonic development is a complex process involving the co-ordinated onset and integration of multiple morphological features and physiological functions. While the molecular basis of morphological development in embryos is relatively well known for traditional model species, the molecular underpinning of the development of physiological functions is not. Here, we used global gene expression profiling to investigate the transcriptional changes associated with the development of morphological and physiological function in the amphipod crustacean Gammarus chevreuxi. We compared the transcriptomes at three timepoints during the latter half of development, characterised by different stages of the development of heart form and function: 10 days post fertilisation (dpf, Early: no heart structure visible), 15 dpf (Middle: heart present but not fully functional), and 18 dpf (Late: regular heartbeat). Gene expression profiles differed markedly between developmental stages, likely representing a change in the activity of different processes throughout the latter period of G. chevreuxi embryonic development. Differentially expressed genes belonged to one of three distinct clusters based on their expression patterns across development. One of these clusters, which included key genes relating to cardiac contractile machinery and calcium handling, displayed a pattern of sequential up-regulation throughout the developmental period studied. Further analyses of these transcripts could reveal genes that may influence the onset of a regular heartbeat. We also identified morphological and physiological processes that may occur alongside heart development, such as development of digestive caeca and the cuticle. Elucidating the mechanisms underpinning morphological and physiological development of non-model organisms will support improved understanding of conserved mechanisms, addressing the current phylogenetic gap between relatively well known model species.

Abstract
Antigen binding fragments (Fabs) used in research (e.g., antibody mimetics, antibody-drug conjugate, bispecific antibodies) are frequently obtained by enzymatic digestion of monoclonal antibodies using immobilised papain. Despite obtaining pure Fab, using immobilised papain to digest IgG has limitations, most notably slow digestion time (more than 8 h), high cost and limited scalability. Here we report a time and cost-effective method to produce pure, active and stable Fab using soluble papain. Large laboratory scale digestion of an antibody (100 mg) was achieved using soluble papain with a digestion time of 30 min and isolated yields of 55–60%. The obtained Fabs displayed similar binding activity as Fabs prepared via immobilised papain digestion. Site-specific conjugation between Fabs and polyethylene glycol (PEG) was carried out to obtain antibody mimetics FpF (Fab-PEG-Fab) indicating that the native disulphide bond had been preserved. Surface-plasmon resonance (SPR) of prepared FpFs showed that binding activity towards the intended antigen was maintained. We anticipate that this work will provide a fast and less costly method for researchers to produce antibody fragments at large scale from whole IgG suitable for use in research.

Abstract
In June 2021, western North America experienced a record-breaking heat wave outside the distribution of previously observed temperatures. While it is clear that the event was extreme, it is not obvious whether other areas in the world have also experienced events so far outside their natural variability. Using a novel assessment of heat extremes, we investigate how extreme this event was in the global context. Characterizing the relative intensity of an event as the number of standard deviations from the mean, the western North America heat wave is remarkable, coming in at over four standard deviations. Throughout the globe, where we have reliable data, only five other heat waves were found to be more extreme since 1960. We find that in both reanalyses and climate projections, the statistical distribution of extremes increases through time, in line with the distribution mean shift due to climate change. Regions that, by chance, have not had a recent extreme heat wave may be less prepared for potentially imminent events.

Abstract
BACKGROUND This study explores live and recorded music listening in the outpatient pain clinic. There is evidence demonstrating the effectiveness of live and recorded music in a hospital setting but a comparison study of this kind has yet to be conducted. METHODS A multimethod survey study design was used. A questionnaire utilizing rating scales was self-administered across two outpatient pain clinic waiting rooms. Patients were included through convenience sampling. In one clinic, a playlist of recorded music curated by two of the authors was provided. In the second clinic, a music therapy student played live music using guitar, flute, and voice. The questionnaire gathered data on music's impact on pain and emotional states, as well as attitudes toward music in the waiting room. Quantitative data was analyzed using descriptive statistics and qualitative data, gathered in the questionnaires open ended question, was analyzed using thematic analysis. RESULTS The questionnaire was completed by 200 adult patients. Patients reported lowered levels of anxiety, stress, and pain in both clinics, as well as a shorter waiting time and more caring experience. Patients in the live music clinic reported that music lowered levels of stress, nervousness, agitation, and pain more than in the recorded music clinic. CONCLUSIONS Participants in this study identified that music is a useful tool in the pain clinic waiting room. This study contributes to evidence that music should be considered as a complimentary treatment for people living with pain and in the wider hospital setting. Additional research is warranted with a control group, pre- and posttesting, and studies of music in hospitals in a range of cultural contexts.

Abstract
Introduction While the global dissemination of vaccines targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a decline in the incidence of infections, the case fatality rates have remained relative stable. A major objective of managing hospitalized patients with documented or suspected COVID-19 infection is the rapid identification of features associated with severe illness using readily available laboratory tests and clinical tools. The sequential organ failure assessment (SOFA) score is a validated tool to facilitate the identification of patients at risk of dying from sepsis. Purpose The aim of this study was to assess the discriminatory accuracy of the SOFA score in predicting clinical decompensation in patients hospitalized with COVID-19 infection. Methods We conducted a retrospective analysis at a three-hospital health system, comprised of one tertiary and two community hospitals, located in the Chicago metropolitan area. All patients had positive SARS-CoV-2 testing and were hospitalized for COVID-19 infection. The primary outcome was clinical decompensation, defined as the composite endpoint of death, ICU admission, or need for intubation. We utilized the most abnormal laboratory values observed during the admission to calculate the SOFA score. Receiver Operating Curves (ROC) were then constructed to determine the sensitivity and specificity of SOFA scores. Results Between March 1st and May 31st 2020, 1029 patients were included in our analysis with 367 patients meeting the study endpoint. The median SOFA score was 2.0 IQR (Q1, Q3 1,4) for the entire cohort. Patients who had in-hospital mortality had a median SOFA score of 4.0 (Q1,Q3 3,7). In patients that met the primary composite endpoint, the median SOFA score was 3.0, IQR (Q1, Q3 2,6). The ROC was 0.776 (95% CI 0.746–0.806, p<0.01). Conclusion The SOFA score demonstrates strong discriminatory accuracy for prediction of clinical decompensation in patients presenting with COVID-19 at our urban hospital system.

Abstract
Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a pandemic which has infected more than 128 million people and led to over 2.8 million deaths worldwide. Although the introduction of efficacious vaccines has led to overall declines in the incidence of SARS-CoV-2 infection, there has been a recent increase in infections once more due to the appearance of mutant strains with higher virulence. It therefore remains vital to identify predictors of poor outcomes in this patient population. Purpose The objective of our study was to identify predictors of prolonged hospitalization, intensive care unit (ICU) admission, intubation, and death in patients infected with SARS-CoV-2. Methods We conducted a retrospective analysis of all patients hospitalized with SARS-CoV-2 at our health system that includes one tertiary care center and two community hospitals located in the Chicago metropolitan area. The main outcome was a composite endpoint of hospitalization >28 days, ICU admission, intubation, and death. Explanatory variables associated with the primary outcome in the bivariate analysis (p<0.05) were included in the multivariable logistic regression model. Statistical analysis was performed using IBM SPSS 25.0. Results Between March 1, 2020 and May 31, 2020, 1029 patients hospitalized with SARS-CoV-2 were included in our analysis. Of these patients, 379 met the composite endpoint. Baseline demographics are described in Table 1. Of note, our cohort consisted of a predominantly minority patient population including 47% Hispanic, 17% African American, 16% Caucasian, and 16% other. In bivariate analysis, age, hypertension, tobacco and alcohol abuse, obesity, coronary artery disease, arrhythmias, valvular heart disease, dyslipidemia, hypertension, stroke, diabetes, documented thrombosis, troponin, CRP, ESR, ferritin, LDH, BNP, D-dimer >5x the upper limit of normal, lactate, and right ventricular outflow tract velocity time integral <9.5 were significant. After multivariable adjustment, explanatory variables associated with the composite endpoint included troponin (OR 2.36; 95% CI 1.08–5.17, p 0.03), D-dimer (OR 1.5; 95% CI 1.23–1.98, p<0.01, lactate (OR 1.58; 95% CI 1.28–1.95, p<0.01), and documented thrombosis (OR 3.56; 95% CI 1.30–8.70, p<.05). Race was not a predictor of poor outcomes in the bivariate or multivariate analysis (Table 2). Conclusions In a large urban cohort with a predominantly minority population, we identified several clinical predictors of poor outcomes. Of note, race was not a predictor of the primary endpoint in this study. While recent literature has demonstrated worse outcomes among racial minorities infected with SARS-CoV-2, our data suggests these variations are related to social determinants of health rather than biologic causes.

Abstract
The domestic dog has inhabited the anthropogenic niche for at least 15 000 years, but despite their impact on human strategies, the lives of dogs and their interactions with humans have only recently become a subject of interest to archaeologists. In the Arctic, dogs rely exclusively on humans for food during the winter, and while stable isotope analyses have revealed dietary similarities at some sites, deciphering the details of provisioning strategies have been challenging. In this study, we apply zooarchaeology by mass spectrometry (ZooMS) and liquid chromatography tandem mass spectrometry to dog palaeofaeces to investigate protein preservation in this highly degradable material and obtain information about the diet of domestic dogs at the Nunalleq site, Alaska. We identify a suite of digestive and metabolic proteins from the host species, demonstrating the utility of this material as a novel and viable substrate for the recovery of gastrointestinal proteomes. The recovered proteins revealed that the Nunalleq dogs consumed a range of Pacific salmon species (coho, chum, chinook and sockeye) and that the consumed tissues derived from muscle and bone tissues as well as roe and guts. Overall, the study demonstrated the viability of permafrost-preserved palaeofaeces as a unique source of host and dietary proteomes.

Abstract
Background: Spinal osteoid osteomas (OOs) are common benign bone tumors that most frequently affect the posterior elements. They occasionally (e.g., 10% of the time) necessitate surgical resection for intractable pain. Given their small size and posterior positions, many may be amenable to minimally invasive surgical approaches. Case Description: We describe two cases of spinal OOs involving patients 11 and 17 years of age with lesions, respectively, at T7 and C4. Conclusion: Minimally invasive approaches for resection of small bony spinal OOs are safe and technically achievable approaches.

Abstract
Background Neurodevelopmental outcomes of asymptomatic children exposed to Zika virus (ZIKV) in utero are not well characterized. Methods We prospectively followed 129 newborns without evidence of congenital Zika syndrome (CZS) up to 24 months of age. Participants were classified as ZIKV exposed or ZIKV unexposed. The Mullen Scales of Early Learning (MSEL) was administered in the participants’ homes at 6, 12, 15, 18, 21, and 24 months of age by trained psychologists. Sociodemographic data, medical history, and infant anthropometry at birth were collected at each home visit. Our primary outcome was the Mullen Early Learning Composite Score (ECL) at 24 months of age between our 2 exposure groups. Secondary outcomes were differences in MSEL subscales over time and at 24 months. Results Of 129 infants in whom exposure status could be ascertained, 32 (24.8%) met criteria for in utero ZIKV exposure and 97 (75.2%) did not. There were no differences in maternal age, maternal educational attainment, birthweight, or gestational age at birth between the 2 exposure groups. The adjusted means and standard errors (SEs) for the ELC score between the ZIKV-exposed children compared to ZIKV-unexposed children were 91.4 (SE, 3.1) vs 96.8 (SE, 2.4) at 12 months and 93.3 (SE, 2.9) vs 95.9 (SE, 2.3) at 24 months. In a longitudinal mixed model, infants born to mothers with an incident ZIKV infection (P = .01) and low-birthweight infants (<2500 g) (P = .006) had lower composite ECL scores. Conclusions In this prospective cohort of children without CZS, children with in utero ZIKV exposure had lower neurocognitive scores at 24 months.

Abstract
Introduction Video consultation involves the live interaction between the doctor and the patient remotely. Prior to the Covid-19 pandemic, the majority of video consultations in primary care were provided by GPs who were not the individual's own GP, which presented safety and continuity issues. This study aims to determine GPs' attitudes to the use of video consultation for their own patients. Methods This was a qualitative study involving semi-structured interviews. Participants were purposively recruited through use of a GP tutor as a key informant and guided by a sampling framework to include those with and without previous video consultation experience. Braun and Clarke thematic analysis was used. Results Participants included eight GPs, half of whom had previously worked with video consultation. Four themes emerged: impact on the consultation, the potential role, and the potential threat to current practice and technology and logistics. There were optimistic and cautious observations within all themes. Conclusion With the increased use of video consultation, Irish General Practice is in a unique position to frame the future its use. The provision of this modality to one's own patients may provide benefit while mitigating some of the pitfalls but would not entirely avoid the potential dangers of video consultation.

Abstract
BACKGROUND The spatial distribution and burden of dengue in sub-Saharan Africa remains highly uncertain, despite high levels of ecological suitability. The goal of this study was to describe the epidemiology of dengue among a cohort of febrile children presenting to outpatient facilities located in areas of western Uganda with differing levels of urbanicity and malaria transmission intensity. METHODS Eligible children were first screened for malaria using rapid diagnostic tests. Children with a negative malaria result were tested for dengue using a combination NS1/IgM/IgG rapid test (SD Bioline Dengue Duo). Confirmatory testing by RT-PCR was performed in a subset of participants. Antigen-capture ELISA was performed to estimate seroprevalence. RESULTS Only 6 of 1416 (0.42%) children had a positive dengue rapid test, while none of the RT-PCR results were positive. ELISA testing demonstrated reactive IgG antibodies in 28 (2.2%) participants with the highest prevalence seen at the urban site in Mbarara (19 of 392, 4.9%, p < 0.001). CONCLUSIONS Overall, these findings suggest that dengue, while present, is an uncommon cause of non-malarial, pediatric febrile illness in western Uganda. Further investigation into the eocological factors that sustain low-level transmission in urban settings are urgently needed to reduce the risk of epidemics.

Abstract
The neurofibromatoses [NF 1, NF 2 and schwannomatosis] are a group of genetic disorders that lead to the development of nervous system tumours and have diverse dermatologic, neurologic, ophthalmic, skeletal and vascular effects. The most common is NF 1 (Neurofibromatosis 1) also known as von Recklinghausen's disease, which is one of the most common human genetic diseases. Oral manifestations of NF 1 are reported in 72% of cases and in one of our cases precipitated attendance at a general dental practitioner (GDP), subsequent diagnosis and genetic screening for family members. This disease may go undiagnosed due to its variable expressivity of symptoms. The pivotal importance of a GDP in the discovery and early referral to an oral or oral and maxillofacial surgeon for further investigation and diagnosis of this condition is highlighted. Knowledge of the most common features of neurofibromatosis can facilitate the speedy referral and subsequent diagnosis of generalized neurofibromatosis, local surgical management of benign neoplasms and long term management of its other clinical features. Dentists should be aware of the classic symptoms of this condition and of their role in long-term care in view of the risk of local recurrence and malignant transformation.

Abstract
Ancient proteomics is being applied to samples dating further and further back in time, with many palaeontological specimens providing protein sequence data for phylogenetic analysis as well as protein degradation studies. However, fossils are a precious material and proteomic analysis is destructive and costly. In this paper we consider three different techniques (ATR-FTIR, MALDI-ToF MS and chiral AA analysis) to screen fossil material for potential protein preservation, aiming to maximise the proteomic information recovered and saving costly time consuming analyses which may produce low quality results. It was found that splitting factor and C/P indices from ATR-FTIR were not a reliable indicator of protein survival as they are confounded by secondary mineralisation of the fossil material. Both MALDI-ToF MS and chiral AA analysis results were able to successfully identify samples with surviving proteins, and it is suggested that one or both of these analyses be used for screening palaeontological specimens. SIGNIFICANCE: This study has shown both chiral amino acid analysis and MALDI-ToF MS are reliable screening methods for predicting protein survival in fossils. Both these methods are quick, cheap, minimally destructive (1 mg and 15 mg respectively) and can provide crucial additional information about the endogeneity of the surviving proteins. It is hoped that the use of these screening methods will encourage the examination of a wide range of palaeontological specimens for potential proteomic analysis. This in turn will give us a better understanding of protein survival far back in time and under different environmental conditions.

Abstract
Abstract
Background
Integration of complementary therapies alongside conventional medical treatment is common and affects health behaviour and outcomes. Nurses frequently interact with patients and their attitudes to these therapies may play a significant role in decision-making. This mixed-method study investigated nurses' attitudes and behaviour towards complementary therapies.
Methods
A sequential exploratory design was utilised. Qualitative data were collected via interviews with nurses working in primary and tertiary settings, in all states of Australia. Interview data underwent thematic analysis. Findings from the interviews informed the development of a questionnaire, which was used to conduct a national online survey. Survey data were descriptively analysed using frequency distributions and percentages.
Results
Nineteen nurses were interviewed and 614 responded to the survey. Themes that emerged from the qualitative data were; Promoting safe care, Seeking complementary therapies knowledge; Supporting holistic health care and Integrating complementary therapies in practice. Survey responses revealed most nurses (77.5%) discussed complementary therapies with patients. More than one half (55.5%) would 'sometimes' recommend complementary therapies and 12.0% would 'almost always/always' do so. The majority (91.8%) believed nurses should have some understanding of complementary therapies. There was a lack of agreement regarding integration of these therapies into nursing practice.
Conclusions
Nurses were generally supportive of patients' interest in complementary therapies and want basic education about these therapies.
Key messages
Nurses working in Australia often engage with patients about complementary therapies. Increasing nurses’ complementary therapy knowledge is likely to promote informed decision-making and improve patient safety.

Abstract
Community initiatives aiming to reduce health inequalities are increasingly common in health policy. Though diverse many such initiatives aim to support residents of disadvantaged places to exercise greater collective control over decisions/actions that affect their lives - which research suggests is an important determinant of health - and some seek to achieve this by giving residents control over a budget. Informed by theoretical work in which community capabilities for collective control are conceptualised as different forms of power, and applying a relational lens, this paper presents findings on the potential role of money as a mechanism to enhance these capabilities from an on-going evaluation of a major place-based initiative being implemented in 150 neighbourhoods across England:The Big Local (BL). The research involved semi-structured interviews with 116 diverse stakeholders, including residents and participant observation in a diverse sample of 10 BL areas. We took a thematic constant comparative approach to the analysis of data from across the sites. The findings suggest that the money enabled the development of capabilities for collective control in these communities primarily by enhancing connectivity amongst residents and with external stakeholders. However, residents had to engage in significant 'relational work' to achieve these benefits and tensions around the money could hinder communities' 'power to act'. Greater social connectivity has been shown to directly affect individual and population health by increasing social cohesion and reducing loneliness. Additionally, supporting enhanced collective control of residents in these disadvantaged communities has the potential to improve population health and reduce health inequalities.

Abstract
This article reports on the responses of 120 teachers and habilitative specialists of multiply handicapped blind and deaf-blind children in Massachusetts to a survey on their use of assistive technology. The respondents reported problems in all areas covered by the survey: knowledge of electronic mobility aids and communication devices; the availability, maintenance, and funding of devices; and adequate information about devices. They especially mentioned the need for resources to assess and match students to appropriate devices and to generate more training for themselves.

Abstract
Background Informed consent is an integral part of clinical practice. There is widespread agreement amongst health professionals that obtaining procedural consent needs to move away from a unidirectional transfer of information to a process of supporting patients in making informed, self‐determined decisions. This review aimed to identify processes and measures that warrant consideration when engaging in consent‐based discussions with competent patients undergoing elective procedures. Methods Formal written guidance from the General Medical Council and Royal College of Surgeons of England, in addition to peer‐reviewed literature and case law, was considered in the formulation of this review. Results A framework for obtaining consent is presented that is informed by the key tenets of shared decision‐making (SDM), a model that advocates the contribution of both the clinician and patient to the decision‐making process through emphasis on patient participation, analysis of empirical evidence, and effective information exchange. Moreover, areas of contention are highlighted in which further guidance and research are necessary for improved enhancement of the consent process. Conclusion This SDM‐centric framework provides structure, detail and suggestions for achieving meaningful consent.

Abstract
Background:Articular manifestations are the most frequent extra-digestive manifestations of Inflammatory Bowel Disease (IBD). Anti-TNF have proved to be as effective on articular symptoms as on IBD’s ones, but have been suspected to induce paradoxical articular manifestations.Objectives:The aims of this study were to describe the frequency, the type and the management of all articular manifestations occurring in patients treated with anti-TNF for IBD and to look for factors associated with their occurrence.Methods:In this retrospective monocentric study, we included all patients who received an anti-TNF for an IBD in our tertiary hospital referent for inflammatory rheumatic and bowel diseases. We searched for all incident articular manifestations occurring during treatment with anti-TNF, including new or recurrent articular manifestations. Characteristics of patients with paradoxical articular manifestations (defined as inflammatory articular symptoms occurring while IBD was in remission, without immunization against anti-TNF) were compared to that of patients without articular manifestations to identify factors associated with their occurrence.Results:Through a systematic search of all IBD patients seen in our tertiary hospital between February 2013 and May 2017, we identified 442 patients (36.2±15 years, 50.5% men) who had ever received an anti-TNF for IBD: Crohn’s disease (n=277), ulcerative colitis (154) and undetermined colitis (n=11). 74 (16.7%) had already a history of inflammatory articular manifestations including 37 patients with a diagnosis of spondyloarthritis (SpA) made before anti-TNF’s beginning.Among them, 115 (26%) patients developed a new articular manifestation after a mean of 20 (±22) months of treatment: mechanical in 56 (12.6%) and inflammatory in 59 (13.3%). Within patients with new inflammatory articular manifestations: 39% were paradoxical, 27% were concomitant of an IBD flare, 27% were associated to an immunization against anti-TNF, 3% were induced lupus, 2% were chondrocalcinosis and 2% were polymyalgia rheumatic. Articular manifestations associated to an immunization were linked to a loss of efficiency of the treatment for 62%, with (42%) or without (20%) associated digestive symptoms and 38% were due to delayed hypersensitivity reaction. Among paradoxical articular manifestations, 83% were new articular symptoms, including 35% of SpA de novo, and 17% were recurrence of known articular manifestations. The only predictive factor of paradoxical articular manifestation was a previous diagnosis of SpA (21.7% vs 6.8%; p=0.02). Paradoxical manifestations improved in 17 patients despite continuation of anti-TNF, methotrexate was added in 2 and anti-TNF was discontinued in only 4 patients.Conclusion:Inflammatory articular manifestations occurred in about 13% of patients treated with anti-TNF for IBD. More than a quarter were linked to an immunization against anti-TNF, which has to be searched in this situation. Less than half of them (39%) were paradoxical. In most of cases, they were transitory and did not require anti-TNF’s discontinuation. The only predictive factor of paradoxical articular manifestations was having a history of SpA.References:[1]Thiebault H, et al.

Abstract
Abstract
Introduction
Sleep problems are highly prevalent in early childhood but often under-identified in pediatric primary care. This study identified the prevalence of caregiver-reported versus primary care provider (PCP)-documented sleep problems and sleep-related health behaviors in young children presenting to well child visits (WCVs).
Methods
Caregivers (85.4% mothers) of 198 young children (2-5 years, M = 3.3, 53.7% female, 62.9% Black) presenting to urban (74.1%) and suburban (25.9%) primary care sites for well child visits (WCVs) completed research surveys on child behavioral sleep problems, snoring, and sleep-related health behaviors (e.g., caffeine consumption) on the day of their child’s WCV. Electronic medical record review was used to identify the rate of PCP-documented sleep problems and related recommendations in the WCV progress note.
Results
Fifteen percent of caregivers reported a child sleep problem according to questionnaire data, which did not significantly differ from the 12.0% of children with a PCP-documented sleep problem in the WCV progress note (p = .31). However, significantly more caregivers (28.3%) reported bedtime difficulties (resistance; tantrums) on questionnaires (p <.001), which were not captured in the 12.0% of WCVs noting sleep problems. A total of 8% of WCVs included child sleep recommendations. Child snoring was reported by 17.0% of caregivers, but was less frequently documented in WCVs (4.5%, p <.001). Although many caregivers reported poor child sleep-related health behaviors, including daily child caffeine consumption (21.1%) and bedroom electronics (62.9%), significantly fewer PCPs documented these issues (caffeine: 2.0%; electronics: 6.6%) or related recommendations (decrease caffeine: 1.0%; eliminate electronics: 3.5%) in the progress note (all p-values <.001).
Conclusion
Although caregiver-endorsed child sleep problems on surveys did not differ from PCP-documented concerns, there are gaps in documenting other problematic sleep-related health behaviors, such as caffeine consumption and electronics use. More resources to address sleep-related health behaviors, as well as sleep problems, in pediatric primary care are needed.

Abstract
Abstract
Introduction
The aim of this study was to assess parent perceptions of sleep problems in young children and parent-identified areas of change in a global sample.
Methods
Caregivers (95.6% mothers) of 1555 infants/toddlers (birth-37 mos; M=12.2 mos; 49.5% male) completed an online survey, representing Indonesia (n=187), Japan (n=718), New Zealand (n=231), Singapore (n=199), and Thailand (n=221). The survey included an abbreviated version of the Brief Infant Sleep Questionnaire, and a list of potential sleep-related areas of change.
Results
36.9% reported a perceived sleep-problem, whereas 92.9% indicated an area of desired change related to their child’s sleep. In terms of areas of change, 82.5% endorsed bedtime/how child falls asleep, 70.0% nighttime sleep, and 57.8% related to the morning. As expected, 99.7% of parents who endorsed a problem indicated a desired change compared to 88.9% who did not perceive a problem, p < .001. Those who noted a problem were more likely to endorse a change at bedtime (92.5%) and during the night (90.1%), compared to the morning (68.8%). There were country-based differences, with caregivers in New Zealand (47.0%) and Singapore (44.2%) more likely to report a child sleep problem compared to Thailand (35.3%), Japan (34.1%) and Indonesia (29.4%), p < .001. No differences were noted in parent-report of desired change across Japan, New Zealand, Singapore, and Thailand (94-96%) but were significantly higher than Indonesia (83.4%).
Conclusion
Although one-third of parents of young children in a global sample indicate a perceived sleep problem, almost all parents wish to change something about their child’s sleep, primarily relate to bedtime and during the night. Sleep education and assessment delivered by health care providers should focus not only on what families consider to be “problematic,” but also what families would like to modify, or improve, about their child’s sleep within a developmentally appropriate framework.

Abstract
Non-invasive SARS-CoV-2 antibody testing is urgently needed to estimate the incidence and prevalence of SARS-CoV-2 infection at the general population level. Precise knowledge of population immunity could allow government bodies to make informed decisions about how and when to relax stay-at-home directives and to reopen the economy. We hypothesized that salivary antibodies to SARS-CoV-2 could serve as a non-invasive alternative to serological testing for widespread monitoring of SARS-CoV-2 infection throughout the population. We developed a multiplex SARS-CoV-2 antibody immunoassay based on Luminex technology and tested 167 saliva and 324 serum samples, including 134 and 118 negative saliva and serum samples, respectively, collected before the COVID-19 pandemic, and 33 saliva and 206 serum samples from participants with RT-PCR-confirmed SARS-CoV-2 infection. We evaluated the correlation of results obtained in saliva vs. serum and determined the sensitivity and specificity for each diagnostic media, stratified by antibody isotype, for detection of SARS-CoV-2 infection based on COVID-19 case designation for all specimens. Matched serum and saliva SARS-CoV-2 antigen-specific IgG responses were significantly correlated. Within the 10-plex SARS-CoV-2 panel, the salivary anti-nucleocapsid (N) protein IgG response resulted in the highest sensitivity for detecting prior SARS-CoV-2 infection (100% sensitivity at ≥10 days post-SARS-CoV-2 symptom onset). The salivary anti-receptor binding domain (RBD) IgG response resulted in 100% specificity. Among individuals with SARS-CoV-2 infection confirmed with RT-PCR, the temporal kinetics of IgG, IgA, and IgM in saliva were consistent with those observed in serum. SARS-CoV-2 appears to trigger a humoral immune response resulting in the almost simultaneous rise of IgG, IgM and IgA levels both in serum and in saliva, mirroring responses consistent with the stimulation of existing, cross-reactive B cells. SARS-CoV-2 antibody testing in saliva can play a critically important role in large-scale "sero"-surveillance to address key public health priorities and guide policy and decision-making for COVID-19.

Abstract
In the state of Colorado, a citizen ballot initiative to reintroduce gray wolves (Canis lupus) is eliciting polarization and conflict among multiple stakeholder and interest groups. Given this complex social landscape, we examined the social context surrounding wolf reintroduction in Colorado as of 2019. We used an online survey of 734 Coloradans representative in terms of age and gender, and we sampled from different regions across the state, to examine public beliefs and attitudes related to wolf reintroduction and various wolf management options. We also conducted a content analysis of media coverage on potential wolf reintroduction in 10 major daily Colorado newspapers from January 2019, when the signature-gathering effort for the wolf reintroduction initiative began, through the end of January 2020, when the initiative was officially added to the ballot. Our findings suggest a high degree of social tolerance or desire for wolf reintroduction in Colorado across geographies, stakeholder groups, and demographics. However, we also find that a portion of the public believes that wolves would negatively impact their livelihoods, primarily because of concerns over the safety of people and pets, loss of hunting opportunities, and potential wolf predation on livestock. These concerns-particularly those related to livestock losses-are strongly reflected in the media. We find that media coverage has focused only on a few of the many perceived positive and negative impacts of wolf reintroduction identified among the public. Our findings highlight the need to account for this diversity of perspectives in future decisions and to conduct public outreach regarding likely impacts of wolf reintroduction.

Abstract
Background Physical fitness is impaired after stroke, yet fitness training after stroke reduces disability. Several international guidelines recommend that fitness training be incorporated as part of stroke rehabilitation. However, information about cost-effectiveness is limited. Methods A decision tree model was used to estimate the cost-effectiveness of a fitness programme for stroke survivors vs. relaxation (control group). This was based on a published randomised controlled trial, from which evidence about quality of life was used to estimate Quality Adjusted Life Years. Costs were based on the cost of the provision of group fitness classes within local community centres and a cost per Quality Adjusted Life Year was calculated. Results The results of the base case analysis found an incremental cost per Quality Adjusted Life Year of £2,343. Conclusions Physical fitness sessions after stroke are a cost-effective intervention for stroke survivors. This information will help make the case for the development of new services.
