A note on the unemployment volatility puzzle
Authors: Kokonas Nikolaos 
Published: March 2022

Abstract
This paper features an economy with frictional labour markets, Nash bargaining, cyclical opportunity cost of employment and demand-determined output. I show that the model generates big responses of unemployment to productivity movements. The key insight is that strongly countercyclical markups amplify the impact of aggregate shocks on the fundamental surplus, and as a consequence, on labour market outcomes. This answers the critique of Chodorow-Reich and Karabarbounis that the cyclicality of the opportunity cost poses a challenge to the solution of the unemployment volatility puzzle.

Abstract
The transcription factor ELONGATED HYPOCOTYL5 (HY5) plays critical roles in plant photomorphogenesis. Previous studies on HY5 have mainly focused on the seedling stage in Arabidopsis (Arabidopsis thaliana), and its functions in other plant species have not been well characterized, particularly at adult stages of development. In this report, we investigated the functions of tomato (Solanum lycopersicum) HY5 (SlHY5) from seedlings to adult plants with a focus on fruits. Genome-edited slhy5 mutants exhibited typical compromised photomorphogenesis in response to various light conditions. The slhy5 mutants showed reduced primary root length and secondary root number, which is associated with altered auxin signaling. SlHY5 promoted chlorophyll biosynthesis from seedling to adult stages. Notably, the promotive role of SlHY5 on chlorophyll accumulation was more pronounced on the illuminated side of green fruits than on their shaded side. Consistent with this light-dependent effect, we determined that SlHY5 protein is stabilized by light. Transcriptome and metabolome analyses in fruits revealed that SlHY5 has major functions in the regulation of metabolism, including the biosynthesis of phenylpropanoids and steroidal glycoalkaloids. These data demonstrate that SlHY5 performs both shared and distinct functions in relation to its Arabidopsis counterpart. The manipulation of SlHY5 represents a powerful tool to influence the two vital agricultural traits of seedling fitness and fruit quality in tomato.

Abstract

Objective
Currently available treatments for neuropathic pain are only modestly efficacious when assessed in randomized clinical trials and work for only some patients in the clinic. Induced-pain or gain-of-function phenotypes have been shown to predict response to analgesics (vs placebos) in patients with neuropathic pain. However, the predictive value of these phenotypes has never been studied in post-traumatic neuropathic pain.

Methods
Mixed-effects models for repeated measures were used to evaluate the efficacy of pregabalin vs placebo in subgroups with induced-pain phenotypes (i.e., hyperalgesia or allodynia) in data from a recent, multinational randomized clinical trial (N = 539) that identified phenotypic subgroups through the use of a structured clinical exam.

Results
The difference in mean pain score between the active and placebo groups (i.e., delta) after 15 weeks of treatment for the subgroup with hyperalgesia was –0.76 (P = 0.001), compared with 0.19 (P = 0.47) for the subgroup that did not have hyperalgesia. The treatment-by-phenotype interaction, which tests whether subgroups have statistically different treatment responses, was significant (P = 0.0067). The delta for the subgroup with allodynia was –0.31 (P = 0.22), compared with –0.30 (P = 0.22) for the subgroup that did not have allodynia (treatment-by-phenotype interaction P = 0.98).

Conclusions
These data suggest that hyperalgesia, but not allodynia, predicts response to pregabalin in patients with chronic post-traumatic neuropathic pain. This study extends the growing data supporting the utility of induced-pain phenotypes to predict response to analgesics in post-traumatic neuropathic pain. Sensory phenotyping in large, multisite trials through the use of a structured clinical exam has the potential to accelerate the development of new analgesics and improve the generalizability of clinical trial results.

AbstractObjectiveWe examined the functional connectivity (FC) in patients with migraine compared with healthy subjects before and after C2 peripheral nerve field stimulation with electroacupuncture (EA-C2-PNfS) to evaluate the effect of EA-C2-PNfS and elucidate the mechanism of migraine.MethodsTwenty-six patients with migraine and 24 healthy controls were recruited. All patients underwent resting state functional magnetic resonance imaging before and after 3 months of EA-C2-PNfS. We evaluated a numerical rating scale, the Headache Impact Test, and the Self-Rating Depression Scale, which assesses depression. Healthy controls underwent magnetic resonance imaging twice at a 3-month interval without acupuncture. An analysis of FC in the region of interest in the pain matrix was performed.ResultsTwenty patients with migraine and 23 healthy controls (mean ± standard deviation: 44.9 ± 12.9 years of age) were included. Three patients had migraine with aura (55.0 ± 18.0 years of age), 11 patients had migraine without aura (MWoA) (45.6 ± 14.6 years of age), and six patients had chronic migraine (40.8 ± 13.9 years of age). The clinical assessments significantly improved after EA-C2-PNfS in the MWoA group only. In FC analysis, the MWoA group showed a significant decrease after EA-C2-PNfS in FC between the right hypothalamus and left insula. Right hypothalamus–related FC was lower before acupuncture in the chronic migraine group than in the MWoA group.ConclusionAfter EA-C2-PNfS for MWoA, significant changes in FC were observed at the hypothalamus and insula. Our results indicate that EA-C2-PNfS could improve migraine headache by modifying pain-related FC.
Omicron Spread in Vaccinated Jurisdictions: a Statistical Study
Authors: Dolgikh Serge 
Published: March 2022

AbstractA correlation hypothesis between the level of vaccination and the rate of spread of the new Covid-19 variant is investigated based on the case and vaccination data from European and North American jurisdictions available in the public domain at the time point of past the crest of the Omicron wave in most jurisdictions. Statistical variables describing the rate of the spread based on observed new case statistics defined and discussed. An unexpected moderate positive correlation between the rate of the variant spread measured by two related parameters and vaccination level based on the dataset in the study is reported. While negative correlation was not statistically excluded, the analysis of the data in the study statistically excluded moderate to strong negative correlation. The results of this work, if confirmed by further independent studies can have implications for development of policies aimed at controlling future course of the Covid-19 pandemic.

AbstractBackgroundImmunization stress-related responses presenting as stroke-like symptoms may develop following COVID-19 vaccination. This study aimed to describe the clinical characteristics of immunization stress-related responses causing stroke-like events following COVID-19 vaccination.MethodsWe conducted a retrospective study of the secondary data of reported adverse events following COVID-19 immunization that presented with neurologic manifestations. Between March 1 and July 31, 2021, we collected and analyzed the medical records of 221 patients diagnosed with stroke-like symptoms following immunization. Demographic and medical data included sex, age, vaccine type, sequence dose, time to event, laboratory data, and recovery status as defined by the modified Rankin score (i.e., defining the degree of severity/dependence, with higher scores indicating greater disability). The affected side was evaluated for associations with the injection site.ResultsIn total, 221 patients were diagnosed with immunization stress-related responses (stroke-like symptoms) following CoronaVac (Sinovac) or ChAdOx1 (AstraZeneca) vaccinations. Most patients (83.7%) were women. The median (interquartile range) age of onset was 34 (28–42) years in patients receiving CoronaVac and 46 (33.5–60) years in those receiving ChAdOx1. The median interval between vaccination and symptom onset for each vaccine type was 60 (16–960) min and 30 (8.8–750) min, respectively. Sensory symptoms were the most common symptomology. Most patients (53.8%) developed symptoms on the left side of the body; 99.5% of the patients receiving CoronaVac and 90% of those receiving ChAdOx1 recovered well (modified Rankin scores ≤2, indicating slight or no disability).ConclusionsImmunization stress-related responses presenting as stroke-like symptoms can develop following COVID-19 vaccination. Symptoms that are more likely to occur on the injection side are transient (i.e., without permanent pathological deficits). Public education and preparedness are important for administering successful COVID-19 vaccination programs.

AbstractSelection of reference genes in quantitative PCR is critical to determine accurate and reliable mRNA expression. Despite this knowledge, not a single study has investigated the expression stability of housekeeping genes to determine their suitability to act as reference gene in SARS-CoV-2 or Covid19 associated mucormycosis (CAM) infections. Herein, we address these gaps by investigating the expression stability of nine most commonly used housekeeping genes including TBP, CypA, B2M, 18S, PGC-1α, GUSB, HPRT-1, β-ACTIN and GAPDH in the patients of varying severity (asymptomatic, mild, moderate and severe). We observed significant differences in the expression of candidate genes across the disease spectrum. Next, using various statistical algorithms (delta Ct, Normfinder, Bestkeeper, RefFinder and GeNorm), we observed that CypA demonstrated the most consistent expression across the patients of varying severity and emerged as the most suitable gene in Covid19, and CAM infections. Incidentally, the most commonly used reference gene GAPDH showed maximum variations and found to be the least suitable. Lastly, comparative evaluation of expression of NRF2 is performed following normalization with GAPDH and CypA to highlight the relevance of an appropriate reference gene. Our results reinforce the idea of a selection of housekeeping genes only after validation especially during infections.

AbstractAimThis systematic review investigates the effectiveness of instructions and feedback with external focus applied with reduced frequency, self-controlled timing and/or in visual or auditory form, on the performance of functional gross motor tasks in children aged 2 to 18 with typical or atypical development.MethodsFour databases (PubMed, Web of Science, Scopus, Embase) were systematically searched (last updated May 31st 2021). Inclusion criteria were: 1. children aged 2 to 18 years old; 2. Instructions/feedback with external focus applied with reduced frequency, self-controlled timing, and/or visual or auditory form as intervention, to learn functional gross motor tasks; 3. Instructions/feedback with external focus applied with continuous frequency, instructor-controlled timing, and/or verbal form as control; 4. performance measure as outcome; 5. (randomized) controlled studies. Article selection and risk of bias assessment (with the Cochrane risk of bias tools) was conducted by two reviewers independently. Due to heterogeneity in study characteristics and incompleteness of the reported data, a best-evidence synthesis was performed.ResultsThirteen studies of low methodological quality were included, investigating effectiveness of reduced frequencies (n = 8), self-controlled timing (n = 5) and visual form (n = 1) on motor performance of inexperienced typically (n = 348) and atypically (n = 195) developing children, for acquisition, retention and/or transfer. For accuracy, conflicting or no evidence was found for most comparisons, at most time points. However, there was moderate evidence that self-controlled feedback was most effective for retention, and limited evidence that visual analogy was most effective for retention and transfer. To improve quality of movement, there was limited evidence that continuous frequency was most effective for retention and transfer.ConclusionMore methodologically sound studies are needed to draw conclusions about the preferred frequency, timing or form. However, we cautiously advise considering self-controlled feedback, visual instructions, and continuous frequency.RegistrationProspero CRD42021225723
Survey of nationwide public perceptions regarding acceptance of wastewater used for community health monitoring in the United States

Published: March 2022

AbstractDuring the coronavirus disease 2019 (COVID-19) pandemic researchers looked for evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in feces dissolved in wastewater samples to assess levels of infection across communities. This activity is known colloquially as sewer monitoring and called wastewater-based epidemiology in academic settings. When used for public health surveillance in the United States, wastewater monitoring is not regulated, although general ethical principles have been described. Prior to this study, no nationwide data existed regarding the public’s perceptions of wastewater being used for community health monitoring. Using an online survey distributed to a representative sample of adults in the Unites States (N=3,083), we investigated the public’s perceptions regarding what is monitored, where monitoring occurs, and privacy concerns related to wastewater monitoring as a public health surveillance tool. Further, the Privacy Attitudes Questionnaire assessed respondents’ general privacy boundaries. The results suggest that respondents supported using wastewater for health monitoring, but within some bounds. Participants were most likely to support or strongly support monitoring for disease (95%), environmental toxins (94%), and terroristic threats (90%, e.g., anthrax). Two-thirds of respondents endorsed no prohibition to locations being monitored while the most common category of location respondents wanted to be prohibited from monitoring was personal residencies. Additionally, the findings suggest that those younger in age and living in an urban area were more supportive of wastewater monitoring, compared to older, suburban dwellers.

Published: March 2022

ABSTRACTBackgroundAcute COVID-19 clinical symptoms have been clearly documented, but long-term functional and symptomatic recovery from COVID -19 is less well described.MethodsA systematic review and meta-analysis were conducted to describe patient-reported outcome measures (PROMs) in adults at least 8 weeks post hospital discharge for COVID-19. Comprehensive database searches in accordance with the PRISMA statement were carried out up till 31/05/2021. Data were narratively synthesized, and a series of meta-analyses were performed using the random-effects inverse variance method.ResultsFrom 49 studies, across 14 countries with between 2-12 months follow up, the most common persisting symptom reported was fatigue with meta-analysis finding 36.6% (95 % CI 27.6 to 46.6, n=14) reporting it at 2-4 months, decreasing slightly to 32.5% still reporting it at >4 months (95% CI 22.6 to 44.2, n=15). This was followed by dyspnoea. Modified MRC score (mMRC) ≥1 was reported in 48% (95% CI 30 to 37, n=5) at 2-4months reducing to 32% (95% CI 22 to 43, n=7) at 4 months. Quality of life (QOL) as assessed by the EQ-5D-5L VAS remained reduced at >4 months (73.6 95% CI 68.1 to 79.1, n=6). Hospitalisation with COVID-19 also resulted in persisting sick leave, change in scope of work, and continued use of primary and secondary healthcare.ConclusionThe symptomatic and functional impact of COVID-19 continues to be felt by patients months after discharge from hospital. This widespread morbidity points towards a multi-disciplinary approach to aid functional recovery.
Phenotypic variability and Gastrointestinal Manifestations/Interventions for growth in Ogden syndrome (also known as NAA10-related Syndrome)
Authors: Sandomirsky Katherine , Marchi Elaine , Gavin Maureen , Amble Karen , Lyon Gholson J. 
Published: March 2022

AbstractOur study of 61 children with Ogden Syndrome, an X-linked disorder due to NAA10 gene mutations, demonstrated a high prevalence of growth failure, with weight and height percentiles often in the failure-to-thrive diagnostic range; although dramatic weight fluctuations and phenotypic variability is evidenced in the growth parameters of this population. Although never previously explored in depth, the gastrointestinal pathology associated with OS includes feeding difficulties in infancy, dysphagia, GERD/silent reflux, vomiting, constipation, diarrhea, bowel incontinence, and presence of eosinophils on esophageal endoscopy, in order from most to least prevalent. Additionally, the gastrointestinal symptom profile for children with this syndrome has been expanded to include eosinophilic esophagitis, cyclic vomiting syndrome, Mallory Weiss tears, abdominal migraine, esophageal dilation, and subglottic stenosis. Although the exact cause of poor growth in OS probands is unclear and the degree of contribution to this problem by GI symptomatology remains uncertain, an analysis including nine G-tube or GJ-tube fed probands demonstrates that G/GJ-tubes are overall efficacious with respect to improvements in weight gain and caregiving. The choice to insert a gastrostomy or gastrojejunal tube to aid with weight gain is often a challenging decision to make for parents, who may alternatively choose to rely on oral feeding, caloric supplementation, calorie tracking, and feeding therapy. In this case, if OS children are not tracking above the FTT range past 1 year of age despite such efforts, they should promptly undergo G-tube placement to avoid prolonged growth failure. If G-tubes are not immediately inducing weight gain after insertion, recommendations include altering formula, increasing caloric input, or exchanging a G-tube for a GJ-tube by means of a minimally invasive procedure. Future directions could include a prospective natural history study investigating whether G/GJ tube insertion affects the cognitive trajectory, rate of reaching developmental milestones, and GI symptomatology of OS children in a positive or negative manner.
Long-term memory in frog-eating bats

AbstractLong-term memory has clear advantages but also has neurological and behavioral costs1–3. Given these opposing selection pressures, understanding how long memories last can shed light on how memory enhances or constrains animals’ abilities to exploit their niches. Although testing memory retention in wild animals is difficult, it is important because captive conditions do not reflect the complex cognitive demands of wild environments, and long-term captivity changes the brain4 (past studies on nonhuman long-term memory are reviewed in Table S1). Here, we trained wild-caught frog-eating bats (Trachops cirrhosus) to find prey by flying to a novel acoustic cue, released them back into the wild, and then re-captured some of them 1-4 years later. When re-tested, all eight ‘experienced’ bats that previously learned the novel prey sounds flew to those sounds within seconds, whereas 17 naïve bats tested with the same sounds showed weak responses. Experienced bats also showed behavior indicating generalization of memories between novel sounds and rewards over time. The frog-eating bat’s remarkably long memory for novel acoustic cues indicates that an ability to remember rarely encountered prey may be advantageous for this predator, and suggests hitherto unknown cognitive abilities in bats.
