Functional response of Franklinothrips vespiformis (Thysanoptera: Aeolothripidae) to eggs and nymphs of Bemisia tabaci (Hemiptera: Aleyrodidae).

The Middle East Asia Minor 1 biotype of Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) is a greenhouse and field crop pest of global significance. The objective of this study was to assess the potential of the generalist predatory thrips, Franklinothrips vespiformis Crawford (Thysanoptera: Aeolothripidae), as a biological control agent for B. tabaci. This was achieved by determining the functional responses of F. vespiformis larvae and adults to the egg and nymphal stages of B. tabaci under laboratory conditions. Analyses consisted of 10 replicates of each predator and prey stage combination on bean leaf discs for a 24-h period. Following logistic regression analyses to determine the functional response type exhibited, response parameters were estimated with nonlinear least squares regression using Roger's equation. Results showed that F. vespiformis larvae and adults exhibited a Type II functional response when feeding on immature B. tabaci. The handling times (Th) of F. vespiformis larvae and adults were magnitudes higher for B. tabaci nymphs than they were for eggs, which were in part driven by the higher attack rates (a) observed on eggs. The maximum attack rate (T/Th) for B. tabaci eggs and nymphs exhibited by first-stage larvae, second-stage larvae, and adult F. vespiformis increased with increasing predator age. Results from this study suggest that F. vespiformis larvae and particularly adults are promising biological control agents for B. tabaci and are efficient predators at both low and high prey densities.

Prognostic and Diagnostic Utility of Serum Biomarkers in Pediatric Traumatic Brain Injury.

Traumatic brain injury (TBI) remains a major cause of morbidity and death among the pediatric population. Timely diagnosis, however, remains a complex task because of the lack of standardized methods that permit its accurate identification. The aim of this study was to determine whether serum levels of brain injury biomarkers can be used as a diagnostic and prognostic tool in this pathology. This prospective, observational study collected and analyzed the serum concentration of neuronal injury biomarkers at enrollment, 24h and 48h post-injury, in 34 children ages 0-18 with pTBI and 19 healthy controls (HC). Biomarkers included glial fibrillary acidic protein (GFAP), neurofilament protein L (NfL), ubiquitin-C-terminal hydrolase (UCH-L1), S-100B, tau and tau phosphorylated at threonine 181 (p-tau181). Subjects were stratified by admission Glasgow Coma Scale score into two categories: a combined mild/moderate (GCS 9-15) and severe (GCS 3-8). Glasgow Outcome Scale-Extended (GOS-E) Peds was dichotomized into favorable (≤4) and unfavorable (≥5) and outcomes. Data were analyzed utilizing Prism 9 and R statistical software. The findings were as follows: 15 patients were stratified as severe TBI and 19 as mild/moderate per GCS. All biomarkers measured at enrollment were elevated compared with HC. Serum levels for all biomarkers were significantly higher in the severe TBI group compared with HC at 0, 24, and 48h. The GFAP, tau S100B, and p-tau181 had the ability to differentiate TBI severity in the mild/moderate group when measured at 0h post-injury. Tau serum levels were increased in the mild/moderate group at 24h. In addition, NfL and p-tau181 showed increased serum levels at 48h in the aforementioned GCS category. Individual biomarker performance on predicting unfavorable outcomes was measured at 0, 24, and 48h across different GOS-E Peds time points, which was significant for p-tau181 at 0h at all time points, UCH-L1 at 0h at 6-9 months and 12 months, GFAP at 48h at 12 months, NfL at 0h at 12 months, tau at 0h at 12 months and S100B at 0h at 12 months. We concluded that TBI leads to increased serum neuronal injury biomarkers during the first 0-48h post-injury. A biomarker panel measuring these proteins could aid in the early diagnosis of mild to moderate pTBI and may predict neurological outcomes across the injury spectrum.

Control of sweet potato whitefly (Bemisia tabaci) using entomopathogenic fungi under optimal and suboptimal relative humidity conditions.

BACKGROUND: Sweet potato whitefly (Bemisia tabaci) is one of the most destructive pests to an extensive range of crops and vegetables. Pesticide-dependent management programs have led to severe health problems, including pesticide poisoning and cancer in human beings, as well as pesticide resistance in insect pests. Entomopathogenic fungi (EPF) are considered safe and highly effective against many pests. Therefore, identifying the pathogenicity and virulence of EPFs against Bemisia tabaci is a valuable addition to the management of their infestations. In this study, we investigated the efficacy of conidia suspensions of Aschersonia aleyrodis, Isaria fumosorosea, Beauveria bassiana, and Akanthomyces muscarius (= Lecanicillium muscarium) against nymphal stages of Bemisia tabaci in cucumber seedlings under both optimal and suboptimal conditions. RESULTS: All of the EPFs demonstrated significant ovicidal effects, with the highest cumulative mortalities observed in Aschersonia aleyrodis (96.46%) and I. fumosorosea-treated (94.60%) seedlings against host eggs and crawlers. Similarly, in the L4-instars experiment, Aschersonia aleyrodis and I. fumosorosea were the most efficient, resulting in cumulative mortalities of 94.82% and 94.75%, respectively. However, Bemisia tabaci cumulative mortalities on seedlings treated with Akanthomyces muscarius (78.36%) and Beauveria bassiana (85.90%) were also significantly different from untreated seedlings (7.10%). Under suboptimal relative humidity (RH) conditions (≤ 45% RH), Aschersonia aleyrodis exhibited greater tolerance to harsh conditions, causing a significantly higher infection rate in L1-L2 nymphs (~92%) compared to the approximately 32% infected young nymphs observed in I. fumosorosea-treated seedlings. CONCLUSION: All the selected EPF were more effective against the young nymphal instars. Our results also highlight the efficacy of Aschersonia aleyrodis under suboptimal conditions. © 2023 The Authors.

Distribution of Scirtothrips dorsalis (Thysanoptera: Thripidae) cryptic species complex in the United States and reproductive host assessment of its dominant member.

Chilli thrips, Scirtothrips dorsalis Hood, is a cryptic species complex of at least 9 species, 2 of which (South Asia 1 and East Asia 1) have been confirmed damaging >50 plant taxa in the United States. To develop a knowledge-based management program for this pest in the United States, the objectives of the study were to (i) survey for S. dorsalis species complex in the suspected regions and (ii) assess the reproductive hosts of the predominant member available. Thrips samples received from collaborators were subjected to morpholo-molecular characterization. Of the 101 thrips populations received across the United States between 2015 and 2021, 71 populations were confirmed as S. dorsalis, with ~25% further identified as East Asia 1, compared with ~41% identified as South Asia 1, suggesting the latter species is more prevalent in the US. East Asia 1 was primarily found in samples collected from Hydrangea sp. (95%) in Massachusetts, New York, and Pennsylvania, indicating geographic range expansion in the Northeast and successful overwintering in areas with hard freezes. While assessing the host range of South Asia 1 (dominant species), 62 plant taxa were evaluated under greenhouse conditions. Among these, 40 feeding and reproductive hosts were confirmed in Florida. We also found 18 new reproductive hosts and 3 feeding hosts of S. dorsalis, which were not previously reported in the literature. The results provide insight into the increasing host range and expanded geographical distribution of S. dorsalis species and will enable the development of a species-specific monitoring and management program.

Ventriculo-inferior-venacaval shunt salvage via endovascular surgery.

INTRODUCTION: Hydrocephalus treatment can be very challenging. While some hydrocephalic patients can be treated endoscopically, many will require ventricular shunting. Frequent shunt issues over a lifetime is not uncommon. Although most shunt malfunctions are of the ventricular catheter or valve, distal failures occur as well. A subset of patients will accumulate non-functioning distal drainage sites. CASE DESCRIPTION: We present a 27-year-old male with developmental delay who was shunted perinatally for hydrocephalus from intraventricular hemorrhage of prematurity. After failure of the peritoneum, pleura, superior vena cava (SVC), gallbladder, and endoscopy, an inferior vena cava (IVC) shunt was placed minimally-invasively via the common femoral vein. We believe this is only the eighth reported ventriculo-inferior-venacaval shunt. IVC occlusion years later was successfully treated with endovascular angioplasty and stenting followed by anticoagulation. To our knowledge, a ventriculo-inferior-venacaval shunt salvaged by endovascular surgery has not been previously described in the literature. CONCLUSION: After failure of the peritoneum, pleura, SVC, gallbladder, and endoscopy, IVC shunt placement is an option. Subsequent IVC occlusion can be rescued by endovascular angioplasty and stenting. Anticoagulation after stenting (and potentially after initial IVC placement) is advised.

Impact of Low-Dose Computed Tomography and Physician Education on Referral for Head Shape.

Imaging before specialist evaluation of abnormal head shape is associated with a delay in evaluation and an increase in radiation exposure. A retrospective cohort study was performed to identify referral patterns before and after the implementation of a low-dose computed tomography (LDCT) protocol and physician education to examine the intervention's impact on time to evaluation and radiation exposure. Six hundred sixty-nine patients with an abnormal head shape diagnosis at a single academic medical center between July 1, 2014 and December 1, 2019 were reviewed. Demographics, referral information, diagnostic testing, diagnoses, and timeline of clinical evaluation were recorded. Before and after the LDCT and physician education intervention, the average ages at initial specialist appointments were 8.82 and 7.75 months, respectively ( P = 0.125). Children referred after our intervention were less likely to have prereferral imaging than children referred prior (odds ratio: 0.59, CI: 0.39-0.91, P = 0.015). Average radiation exposure per patient before referral decreased from 14.66 mGy to 8.17 mGy ( P = 0.021). Prereferral imaging, referral by a non-pediatrician, and non-Caucasian race were associated with older age at the initial specialist appointment. Widespread craniofacial center adoption of an LDCT protocol and improved clinician knowledge may lead to a reduction in late referrals and radiation exposure in pediatric patients with an abnormal head shape diagnosis.

Implementation of a Drug Screening Platform to TargetGch1 Expression in Injured Mouse Dorsal Root Ganglion Neurons.

Management of neuropathic pain is notoriously difficult; current analgesics, including anti-inflammatory- and opioid-based medications, are generally ineffective and can pose serious side effects. There is a need to uncover non-addictive and safe analgesics to combat neuropathic pain. Here, we describe the setup of a phenotypic screen whereby the expression of an algesic gene,Gch1, is targeted. GCH1 is the rate-limiting enzyme in the de novo synthesis of tetrahydrobiopterin (BH4), a metabolite linked to neuropathic pain in both animal models and in human chronic pain sufferers.Gch1is induced in sensory neurons after nerve injury and its upregulation is responsible for increased BH4 levels. GCH1 protein has proven to be a difficult enzyme to pharmacologically target with small molecule inhibition. Thus, by establishing a platform to monitor and target inducedGch1 expression in individual injured dorsal root ganglion (DRG) neurons in vitro, we can screen for compounds that regulate its expression levels. This approach also allows us to gain valuable biological insights into the pathways and signals regulating GCH1 and BH4 levels upon nerve injury. This protocol is compatible with any transgenic reporter system in which the expression of an algesic gene (or multiple genes) can be monitored fluorescently. Such an approach can be scaled up for high-throughput compound screening and is amenable to transgenic mice as well as human stem cell-derived sensory neurons. Graphical overview.

Vitamin D supplementation in children and young adults with persistent proteinuria secondary to glomerular disease.

BACKGROUND: Vitamin D deficiency is common in glomerular disease. Supplementation may be ineffective due to ongoing urinary losses of vitamin D binding protein. We sought to determine if daily cholecalciferol supplementation would increase vitamin D concentrations in children with glomerular disease and persistent proteinuria, without adverse effects. METHODS: Eighteen participants at least 5 years of age with primary glomerular disease and urine protein:creatinine ratio ≥ 0.5 were enrolled from four pediatric nephrology practices to receive cholecalciferol supplementation: 4,000 IU or 2,000 IU per day for serum 25 hydroxyvitamin vitamin D (25OHD) concentrations < 20 ng/mL and 20 ng/mL to < 30 ng/mL, respectively. Measures of vitamin D and mineral metabolism were obtained at baseline and weeks 6 and 12. Multivariable generalized estimating equation (GEE) regression estimated mean percent changes in serum 25OHD concentration. RESULTS: Median baseline 25OHD was 12.8 ng/mL (IQR 9.3, 18.9) and increased to 27.8 ng/mL (20.5, 36.0) at week 6 (p < 0.001) without further significant increase at week 12. A total of 31% of participants had a level ≥ 30 ng/mL at week 12. Supplementation was stopped in two participants at week 6 for mildly elevated calcium and phosphorus, respectively, with subsequent declines in 25OHD of > 20 ng/mL. In the adjusted GEE model, 25OHD was 102% (95% CI: 64, 141) and 96% (95% CI: 51, 140) higher versus baseline at weeks 6 and 12, respectively (p < 0.001). CONCLUSION: Cholecalciferol supplementation in vitamin D deficient children with glomerular disease and persistent proteinuria safely increases 25OHD concentration. Ideal dosing to fully replete 25OHD concentrations in this population remains unknown. CLINICAL TRIAL: NCT01835639.

Considerations for Choice of Cranioplasty Material for Pediatric Patients.

INTRODUCTION: Optimal material and timing of cranioplasty in the pediatric population continue to be debated. Autologous and alloplastic materials have various indications for use and risk factors for complications. METHODS: A single-center retrospective cohort study was undertaken of all pediatric patients who underwent cranioplasty with any material from 1991-2021. RESULTS: 149 cranioplasty implants were included. Younger age (6 years old or under), a diagnosis of craniosynostosis as reason for implant, use of autologous bone, and shorter times to cranioplasty were predictive of need for revision surgery. No factors studied had a statistically significant impact on rate of removal of implant at time of revision surgery. CONCLUSION: Autologous and alloplastic cranioplasty materials both have good outcomes with low rates of revision surgery in the pediatric population. Alloplastic implants may be considered in the setting of infection as reason for craniectomy given the lower rate of revision surgery and need for removal. Patients with craniosynostosis as reason for cranioplasty have a higher risk of requiring revision or additional surgeries, regardless of implant used.

Projected network performance for next generation aerosol monitoring systems.

Aerosol monitoring for radioactivity is a mature and proven technology. However, by improving key specifications of aerosol monitoring equipment, more samples per day can be collected and analyzed with the same minimum detectable concentrations as current systems. This work models hypothetical releases of 140Ba and 131I over a range of magnitudes corresponding to the inventory produced from the fission of about 100 g to 1 kiloton TNT-equivalent of 235U. The releases occur over an entire year to incorporate the natural variability in atmospheric transport. Sampling equipment located at the 79 locations for radionuclide stations identified in the Comprehensive Nuclear-Test-Ban Treaty (CTBT) for the International Monitoring System are used to determine the detections of the individual releases. Alternative collection schemes in next generation equipment that collect 2, 3, or 4 samples per day, rather than the current 1 sample per day, would result in detections in many more samples at more stations with detections for a given release level. The authors posit that next generation equipment will result in increased network resilience to outages and improved source-location capability for lower yield source releases. The application of dual-detector and coincidence measurements to these systems would significantly boost sensitivity for some isotopes and would further enhance the monitoring capability.

A Case Report of Breakthrough Infections With 2 SARS-CoV-2 Variants in a Lung Transplant Patient.

A lung transplant (LT) patient developed 2 distinct episodes of COVID-19, confirmed by whole-genome sequencing, which was caused by the Delta, and then followed 6 weeks later, by the Omicron variant. The clinical course with Omicron was more severe, leading us to speculate that Omicron may not be any milder among LT patients. We discuss the potential mechanisms behind the Omicron not being any milder among LT patients and emphasize the need for outcomes data among these patients. Until such data become available, it may be prudent to maintain clinical equipoise as regards the relative virulence of the newer variants among LT patients.

Phenotypic drug screen uncovers the metabolic GCH1/BH4 pathway as key regulator of EGFR/KRAS-mediated neuropathic pain and lung cancer.

Increased tetrahydrobiopterin (BH4) generated in injured sensory neurons contributes to increased pain sensitivity and its persistence. GTP cyclohydrolase 1 (GCH1) is the rate-limiting enzyme in the de novo BH4 synthetic pathway, and human single-nucleotide polymorphism studies, together with mouse genetic modeling, have demonstrated that decreased GCH1 leads to both reduced BH4 and pain. However, little is known about the regulation of Gch1 expression upon nerve injury and whether this could be modulated as an analgesic therapeutic intervention. We performed a phenotypic screen using about 1000 bioactive compounds, many of which are target-annotated FDA-approved drugs, for their effect on regulating Gch1 expression in rodent injured dorsal root ganglion neurons. From this approach, we uncovered relevant pathways that regulate Gch1 expression in sensory neurons. We report that EGFR/KRAS signaling triggers increased Gch1 expression and contributes to neuropathic pain; conversely, inhibiting EGFR suppressed GCH1 and BH4 and exerted analgesic effects, suggesting a molecular link between EGFR/KRAS and pain perception. We also show that GCH1/BH4 acts downstream of KRAS to drive lung cancer, identifying a potentially druggable pathway. Our screen shows that pharmacologic modulation of GCH1 expression and BH4 could be used to develop pharmacological treatments to alleviate pain and identified a critical role for EGFR-regulated GCH1/BH4 expression in neuropathic pain and cancer in rodents.

Effectiveness of Social Needs Screening and Interventions in Clinical Settings on Utilization, Cost, and Clinical Outcomes: A Systematic Review.

Objective: This systematic review examined and synthesized peer-reviewed research studies that reported the process of integrating social determinants of health (SDOH) or social needs screening into electronic health records (EHRs) and the intervention effects in the United States. Methods: Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, a systematic search of Scopus, Web of Science Core Collection, MEDLINE, and Cochrane Central Register of Clinical Trials was performed. English language peer-reviewed studies that reported the process of integrating SDOH or social needs screening into EHRs within the U.S. health systems and published between January 2015 and December 2021 were included. The review focused on process measures, social needs changes, health outcomes, and health care cost and utilization. Results: In total, 28 studies were included, and half were randomized controlled trials. The majority of the studies targeted multiple SDOH domains. The interventions vary by the levels of intensity of their approaches and heterogeneities in outcome measures. Most studies (82%, n=23) reported the findings related to the process measures, and nearly half (43%, n=12) reported outcomes related to social needs. By contrast, only 39% (n=11) and 32% (n=9) of the studies reported health outcomes and impact on health care cost and utilization, respectively. Findings on patients' social needs change demonstrated improved access to resources. However, findings were mixed on intervention effects on health and health care cost and utilization. We also identified gaps in implementation challenges to be overcome. Conclusion: Our review supports the current policy efforts to increase U.S. health systems' investment toward directly addressing SDOH. While effective interventions can be more complex or resource intensive than an online referral, health care organizations hoping to achieve health equity and improve population health must commit the effort and investment required to achieve this goal.

COVID-19 Vaccination is Associated With Favorable Outcomes Among Lung Transplant Patients With Breakthrough Infections.

BACKGROUND: There are limited data regarding the clinical efficacy of COVID-19 vaccines among lung transplant (LT) patients. METHODS: We included all LT patients diagnosed with COVID-19 between March 1, 2020, and December 10, 2021 (n = 84; median age 55, range, 20-73 years; males 65.5%). The study group was divided into 3 groups based on the vaccination status (patients who did not complete the primary series for any of the vaccines: n = 58; those with 2 doses of messenger RNA (mRNA) or 1 dose of the adenoviral vector vaccine, vaccinated group: n = 16; those with at least 1 additional dose beyond the primary series, boosted group: n = 10). RESULTS: Pulmonary parenchymal involvement on chest computed tomography scan was less common among the boosted group (P = .009). The proportion of patients with new or worsening respiratory failure was significantly lower among the vaccinated and boosted groups and these patients were significantly more likely to achieve the composite endpoint of oxygen-dependence free survival (P = .02). On multivariate logistic regression analysis, higher body mass index, restrictive lung disease as the transplant indication, and preinfection chronic lung allograft dysfunction were independently associated with acute or acute on chronic respiratory failure while being on therapeutic dose anticoagulation and having received the booster dose had a protective effect. CONCLUSION: COVID-19 vaccines appear to have several favorable effects among LT patients with breakthrough infections including lower likelihood of allograft involvement on imaging (among boosted patients), need of hospitalization, and complications such as new or worsening respiratory failure.

Barriers and facilitators of health among older adult immigrants in the United States: an integrative review of 20 years of literature.

BACKGROUND: There are over seven million older adult immigrants in the United States, and that number is expected to increase. Older adult immigrants in the United States have unique factors that influence their health. METHODS: In this integrative review, we systematically review 20 years of peer-reviewed literature on the barriers (i.e. isolation, lack of English Language Proficiency, low health literacy, lack of SES resources, discrimination) and facilitators (i.e. English Language Proficiency and maintaining ones native language, social support, culturally sensitive providers, healthcare access) of health among older adult immigrants in the United States. RESULTS: We found differing uses of the term 'older adult', emphasis on the lack of homogeneity among older adult immigrants, social support and isolation as significant barriers and facilitators of older adult immigrant health, and inconsistencies in uses and definitions of acculturation. We also examined relevant theories in the literature. Based on the literature review, focusing on Acculturation Theory, Social Cognitive Theory, and Successful Aging Theory, combining these three theories with findings from the literature to create the Older Adult Immigrant Adapted Model for Health Promotion. CONCLUSIONS: Public health strives to promote health and prevent adverse health outcomes. Our integrative review not only systematically and thoroughly explicates 20 years of literature, but the Older Adult Immigrant Adapted Model for Health Promotion, provides guidance for future research and interventions.

The current landscape of immunotherapy for pediatric brain tumors.

Pediatric central nervous system tumors are the most common solid malignancies in childhood, and aggressive therapy often leads to long-term sequelae in survivors, making these tumors challenging to treat. Immunotherapy has revolutionized prospects for many cancer types in adults, but the intrinsic complexity of treating pediatric patients and the scarcity of clinical studies of children to inform effective approaches have hampered the development of effective immunotherapies in pediatric settings. Here, we review recent advances and ongoing challenges in pediatric brain cancer immunotherapy, as well as considerations for efficient clinical translation of efficacious immunotherapies into pediatric settings.

ECMO Long Haulers: A Distinct Phenotype of COVID-19-Associated ARDS With Implications for Lung Transplant Candidacy.

BACKGROUND: Studies indicate that the recovery from coronavirus disease 2019 (COVID-19)-associated acute respiratory distress syndrome may be slower than other viral pneumonia. There are limited data to guide decisions among patients who need extracorporeal membrane oxygenation (ECMO) support, especially the expected time of recovery and considering lung transplantation (LT). METHODS: This was a retrospective chart review of patients with COVID-19-associated acute respiratory distress syndrome placed on ECMO between March 1, 2020, and September 15, 2021 (n = 20; median age, 44 y; range, 22-62 y; male:female, 15:5). We contrasted the baseline variables and clinical course of patients with and without the need for ECMO support >30 d (ECMO long haulers, n = 10). RESULTS: Ten patients met the criteria for ECMO long haulers (median duration of ECMO, 86 d; range, 42-201 d). The long haulers were healthier at baseline with fewer comorbidities but had worse pulmonary compliance and higher partial pressure of CO2. They had a significantly higher number of membrane oxygenator failures, changes to their cannulation sites, and suffer more complications on ECMO. One of the long hauler was bridged to LT while another 6 patients recovered and were discharged. Overall survival was better among the ECMO long haulers (70% versus 20%; 9.3, 1.2-73; P = 0.03). CONCLUSIONS: Despite worse pulmonary physiology, frequent complications, and a tortuous hospital course that may appear to portend a poor prognosis, ECMO long haulers have the potential to recover and be weaned off ECMO without the need for LT. A customized approach comprising a more conservative timeline for the consideration of LT may be prudent among these patients.

A qualitative analysis of perceptions of and reactions to COVID-19.

OBJECTIVE: To understand communities' perceptions, beliefs, and health-related behavior choices related to COVID-19 in order to guide public health nursing communication and interaction with patients and the community. DESIGN: A qualitative study, guided by the Health Belief Model (HBM), strove to comprehend the perceptions and reactions to COVID-19 among Wisconsinites. SAMPLE: Twenty-five diverse Wisconsin residents aged 18 or older. MEASUREMENTS: Semi-structured interviews provided information about individuals' attitudes, perceptions, and reactions to COVID-19. Interviews were audio-recorded, transcribed, and thematic analysis was conducted to identify themes. RESULTS: We identified three major themes: (1) "health care starts way before you ever enter the doors of a healthcare facility"; (2) "to live in a society is to help each other"; and (3) mental health as impacted by COVID-19. CONCLUSIONS: This study demonstrated the need for greater public health support, as well as the role of Social Determinants of Health. Understanding perceptions and reactions to COVID-19 can help public health nurses understand and better respond to future pandemics.
