Association of fatigue with disease activity and clinical manifestations in patients with crohn's disease and ulcerative colitis: an observational cross-sectional study in the United States.

INTRODUCTION: Fatigue imposes a socioeconomic burden on patients with Crohn's disease (CD) and ulcerative colitis (UC). We assessed the prevalence of fatigue among patients with CD or UC and identified disease activity measures associated with fatigue. METHODS: Data from the Study of a Prospective Adult Research Cohort with Inflammatory Bowel Disease (SPARC IBD) were analysed separately for CD and UC. Fatigue was defined based on a subjective and dichotomic questionnaire. Patients indicated if they experienced fatigue within the last week. Overall prevalence of fatigue was analysed using descriptive and contingency tables. Demographics, clinical characteristics, disease activity (measures include Physician's Global Assessment for both CD and UC, short CD Activity Index for CD, and Ulcerative Colitis Disease Activity Index for UC), symptoms, and patient-reported outcomes were compared between patients with and without fatigue. Multivariable logistic regression models were constructed to identify symptoms and disease activity measures associated with fatigue. RESULTS: The study included 903 patients with CD and 443 patients with UC. Fatigue was reported in 47.7% of patients with CD and 40.9% of patients with UC. In patients with CD, abdominal pain, bowel incontinence, depressive symptoms, reduced general well-being, and night-time bowel movements were associated with fatigue. In patients with UC, depressive symptoms, reduced general well-being, moderate or severe disease activity by the physician's global assessment, and night-time bowel movement were significantly associated with fatigue. CONCLUSIONS: Fatigue is a common symptom among patients with CD or UC and is associated with higher levels of disease activity and reduced general well-being.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), can lead to fatigue in many patients regardless of their disease severity. Fatigue not only affects patients quality of life but also their ability to work and their mental health. However, research specific to the IBD related symptoms that contribute to fatigue in these patients is not currently available, especially in the United States (U.S.). To address this gap, real-world data was analyzed to understand how common fatigue is among patients with CD and UC in the U.S and clinical symptoms that co-occur with fatigue. We found that fatigue affects more than 40% of the patients. Our results suggest that fatigue is correlated with more severe disease symptoms and overall lower well-being among patients with CD and UC.

Defining the value of medical microbiology consultation.

Medical microbiologists, defined as doctoral-level laboratory directors with subspecialty training in medical microbiology, lead the clinical laboratory operations through activities such as clinical consultations, oversight of diagnostic testing menu, institutional leadership, education, and scholastic activities. However, unlike their clinical colleagues, medical microbiologists are largely unable to bill for clinical consultations performed within the hospital and, therefore, unable to generate relative value units or a similar quantifiable metric. As hospital budgets tighten and justification of staffing becomes a necessity, this may present a challenge to the medical microbiologist attempting to prove their value to the organization. To aid in providing tangible data, the Personnel Standards and Workforce subcommittee of the American Society for Microbiology conducted a multi-center study across seven medical centers to document clinical consultations and their impact. Consults were generated equally from internal (laboratory-based) and external (hospital-based) parties, with the majority directly impacting patient management. Near universal acceptance of the medical microbiologist's recommendation highlights the worth derived from their expertise. External consults required more time commitment from the medical microbiologist than internal consults, although both presented ample opportunity for secondary value, including impact through stewardship, education, clinical guidance, and cost reduction. This study is a description of the content and impact of consultations that underscore the importance of the medical microbiologist as a key member of the healthcare team. IMPORTANCE: Medical microbiologists are invaluable to the clinical microbiology laboratory and the healthcare system as a whole. However, as medical microbiologists do not regularly generate relative value units, capturing and quantifying the value provided is challenging. As hospital budgets tighten, justification of staffing becomes a necessity. To aid in providing tangible data, the Personnel Standards and Workforce subcommittee of the American Society for Microbiology conducted a multi-center study across seven medical centers to document clinical consultations and their impact. To our knowledge, this is the first study to provide detailed evaluation of the consultative value provided by medical microbiologists.

The Clinical Course of Bowel Urgency Severity Among Patients with Inflammatory Bowel Disease-A Real-World Study.

BACKGROUND: Bowel urgency is a highly burdensome symptom among patients with inflammatory bowel disease (IBD). OBJECTIVES: To assess changes in severity of bowel urgency and identify predictors of worsening or improvement among patients with Crohn's disease (CD) and ulcerative colitis (UC) at 6 months from their enrollment visit. METHODS: Data from patients in the Study of a Prospective Adult Research Cohort with IBD were analyzed. Enrolled patients with CD or UC with 6-month visits were included. Changes and predictors of bowel urgency severity over 6 months in patients with CD or UC were examined using two separate analyses: (a) "worsening" versus "no change" excluding those with moderate-to-severe bowel urgency at enrollment, and (b) "improvement" versus "no change" excluding those with no bowel urgency at enrollment. The enrollment characteristics were compared within these groups. RESULTS: At baseline, in both CD and UC, use of biologics and/or immunomodulators at enrollment was similar across cohorts. Among patients with CD, 206 of 582 (35.4%) reported worsening, and 195 of 457 (42.7%) reported improvement in bowel urgency. Younger age (P = 0.013) and moderate-to-severe bowel urgency (P < 0.001) were associated with improvement. Moderate bowel urgency (P = 0.026) and bowel incontinence while awake (P = 0.022) were associated with worsening. Among patients with UC, 84 of 294 (28.6%) reported worsening, and 111 of 219 (50.7%) reported improvement in bowel urgency. Higher symptomatic disease severity (P = 0.011) and more severe bowel urgency (P < 0.001) were associated with improvement. CONCLUSIONS: Bowel urgency is an unpredictable and unstable symptom among patients with IBD. Over 50% of patients with CD or UC experienced either worsening or improvement at 6 months postenrollment.

WHAT IS KNOWN ABOUT BOWEL URGENCY IN INFLAMMATORY BOWEL DISEASE (IBD)?: Around six to eight in every ten patients with inflammatory bowel disease suffer from bowel urgency, a sudden need to have bowel movement. Many patients with IBD perceive bowel urgency as a bothersome symptom impacting their everyday activities. WHY DID WE DO THIS STUDY?: Despite the importance of bowel urgency, the changes in bowel urgency severity among the IBD-affected US population are yet to be fully known. We aimed to assess changes in severity of bowel urgency in patients with Crohn's disease (CD) or ulcerative colitis (UC) at 6 months. WHAT HAVE WE FOUND FROM THIS STUDY?: Bowel urgency is a common and unpredictable symptom among patients with CD and UC. Over 50% of patients reported that the severity of bowel urgency has either worsened or improved at the 6 months postenrollment. While about 40­50% of IBD patients reported improvement, about 30% reported worsening, suggesting a lack of effective therapies to treat bowel urgency. FUTURE IMPLICATION: There is a need for advanced therapies to resolve bowel urgency in patients with CD and UC.

Spatial targeting of irrigation development and water resource management to mitigate vector-borne disease.

Scaling irrigated agriculture is a global strategy to mitigate food insecurity concerns. While expanding irrigated agriculture is critical to meeting food production demands, it is important to consider how these land use and land cover changes (LULCC) may alter the water resources of landscapes and impact the spatiotemporal epidemiology of disease. Here, a generalizable method is presented to inform irrigation development decision-making aimed at increasing crop production through irrigation while simultaneously mitigating malaria risk to surrounding communities. Changes to the spatiotemporal patterns of malaria vector (Anopheles gambiae s.s.) suitability, driven by irrigated agricultural expansion, are presented for Malawi's rainy and dry seasons. The methods presented may be applied to other geographical areas where sufficient irrigation and malaria prevalence data are available. Results show that approximately 8.60% and 1.78% of Malawi is maximally suitable for An. gambiae s.s. breeding in the rainy and dry seasons, respectively. However, the proposed LULCC from irrigated agriculture increases the maximally suitable land area in both seasons: 15.16% (rainy) and 2.17% (dry). Proposed irrigation development sites are analyzed and ranked according to their likelihood of increasing malaria risk for those closest to the schemes. Results illustrate how geospatial information on the anticipated change to the malaria landscape driven by increasing irrigated agricultural extent can assist in altering development plans, amending policies, or reassessing water resource management strategies to mitigate expected changes in malaria risk.

Critical domains for NACC2-NTRK2 fusion protein activation.

Neurotrophic receptor tyrosine kinases (NTRKs) belong to the receptor tyrosine kinase (RTK) family. NTRKs are responsible for the activation of multiple downstream signaling pathways that regulate cell growth, proliferation, differentiation, and apoptosis. NTRK-associated mutations often result in oncogenesis and lead to aberrant activation of downstream signaling pathways including MAPK, JAK/STAT, and PLCγ1. This study characterizes the NACC2-NTRK2 oncogenic fusion protein that leads to pilocytic astrocytoma and pediatric glioblastoma. This fusion joins the BTB domain (Broad-complex, Tramtrack, and Bric-a-brac) domain of NACC2 (Nucleus Accumbens-associated protein 2) with the transmembrane helix and tyrosine kinase domain of NTRK2. We focus on identifying critical domains for the biological activity of the fusion protein. Mutations were introduced in the charged pocket of the BTB domain or in the monomer core, based on a structural comparison of the NACC2 BTB domain with that of PLZF, another BTB-containing protein. Mutations were also introduced into the NTRK2-derived portion to allow comparison of two different breakpoints that have been clinically reported. We show that activation of the NTRK2 kinase domain relies on multimerization of the BTB domain in NACC2-NTRK2. Mutations which disrupt BTB-mediated multimerization significantly reduce kinase activity and downstream signaling. The ability of these mutations to abrogate biological activity suggests that BTB domain inhibition could be a potential treatment for NACC2-NTRK2-induced cancers. Removal of the transmembrane helix leads to enhanced stability of the fusion protein and increased activity of the NACC2-NTRK2 fusion, suggesting a mechanism for the oncogenicity of a distinct NACC2-NTRK2 isoform observed in pediatric glioblastoma.

Surgical outcomes and revision rates for velopharyngeal insufficiency (VPI) in syndromic and non-syndromic children: A systematic review and meta-analysis.

PURPOSE: To evaluate pre- and post-operative resonance, surgical technique, revision rate, and revision indication among syndromic and non-syndromic children with velopharyngeal insufficiency (VPI). MATERIALS AND METHODS: A systematic review was conducted through July 2022. Children surgically treated for VPI were included. A meta-analysis of single means, proportions, comparison of proportions, and mean differences with 95 % confidence interval [CI] was conducted. RESULTS: Twenty-three articles (n = 1437) were included in the analysis. The most common surgery was Sphincter Pharyngoplasty (SP), 62.6 % [31.3-88.9] for syndromic and 76.3 % [37.5-98.9] for non-syndromic children. Among all surgical techniques, for syndromic and non-syndromic children, 54.8 % [30.9-77.5] and 73.9 % [61.3-84.6] obtained normal resonance post-operatively, respectively. Syndromic patients obtained normal resonance post-operatively in 83.3 % [57.7-96.6] of Combined Furlow Palatoplasty and Sphincter Pharyngoplasty (CPSP), 72.6 % [54.5-87.5] of Pharyngeal Flap (PF), and 45.1 % [13.2-79.8] of Sphincter Pharyngoplasty (SP) surgeries. Non-syndromic patients obtained normal resonance post-operatively in 79.2 % [66.4-88.8] of PF and 75.2 % [61.8-86.5] of SP surgeries. The revision rate for syndromic and non-syndromic patients was 19.9 % [15.0-25.6] and 11.3 % [5.8-18.3], respectively. The difference was statistically significant, 8.6 % [2.9-15.0, p = 0.003]. Syndromic patients who underwent PF were least likely to undergo revision surgery as compared to SP and CPSP, 7.7 % [2.3-17.9] vs. 23.7 % [15.5-33.1] and 15.3 % [2.8-40.7], respectively. CONCLUSIONS: Syndromic children had higher revision rates and were significantly less likely to obtain normal resonance following primary surgery than non-syndromic patients. Among syndromic children, PF and CPSP have been shown to improve resonance and reduce revision rates more so than SP alone.

The pharmacist's role in optimizing medication management before, during, and after minimally invasive and bariatric surgery.

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: Minimally invasive surgery (MIS) with integrated enhanced recovery pathways (ERPs) helps reduce length of stay and improve surgical outcomes. As these procedures have become more prevalent over time, pharmacists are in key positions to manage medications in the perioperative space to help optimize transitions of care and reduce safety events. Here we identify several clinical areas across phases of care for these procedures in which the knowledge and guidance of pharmacists, as members of the interprofessional team, are paramount. SUMMARY: Perioperative pharmacy expertise is often required for MIS procedures in the areas of acid suppression, antithrombotic management, blood glucose control, drug formulation, immunosuppressant optimization, pain mitigation, and postoperative nausea and vomiting prevention and treatment. For each MIS procedure, pharmacists should identify and consider diet and anatomical changes as well as patient- and surgery-specific risk factors. Pharmacists can then utilize their knowledge of the pharmacokinetics and pharmacodynamics of individual medications along with evidence-based medicine to recommend selection of appropriate agents. CONCLUSION: Pharmacist contributions to perioperative medication management for MIS procedures can improve care as surgical patients navigate transitions through the perioperative setting. Pharmacists can further incorporate medication expertise through development and implementation of institutional MIS protocols within the context of ERPs. As such, any pharmacist should feel empowered to aid in the care of surgical patients.

Direct impact of the COVID-19 pandemic on rhinology practice.

KEY POINTS: The pandemic caused an increase in computed tomography imaging in patients with sinusitis, which persisted post-COVID. Nasal endoscopies significantly decreased during COVID but returned to pre-COVID levels in 2022. The management of cerebrospinal fluid leaks, tumors, and orbital pathology was not impacted by the pandemic.

Early Use of Biologics Reduces Healthcare Costs in Crohn's Disease: Results from a United States Population-Based Cohort.

BACKGROUND: Early initiation of biologics in moderate-to-severe Crohn's disease (CD) may significantly alter disease progression, resulting in better patient outcomes. Limited real-world data exist on the impact of early biologic use in patients with CD in the United States. AIMS: We aimed to characterize biologic initiation and subsequent healthcare resource utilization (HCRU) in adults with recently diagnosed CD. METHODS: Patients with CD who initiated biologic treatment within 2 years of diagnosis (index date) were identified from medical and pharmacy claims (Merative L.P. MarketScan Database from 2010 to 2016) and classified as early (≤ 12 months post-index) or late (> 12-24 months post-index) biologic initiators. Propensity score matching balanced patient characteristics up to 1 year post-index. Differences in HCRU frequency and costs 1-2 years post-index were compared between the matched groups. RESULTS: After propensity score matching, 672 pairs of early and late biologic initiators were identified. Patients who initiated biologics early had fewer outpatient visits (15.5 vs 19.8, 95% confidence interval [CI] for difference: 2.7, 6.1) and lower total medical costs ($13,646.20 vs $22,180.70, 95% CI for difference: 4748.9, 12,320.1) 1-2 years post-index than late biologic initiators. Early biologic initiators had higher medication costs 1-2 years post-index ($33,766.30 vs $30,580.70, 95% CI: 546.1, 5825.1) but lower combined medical and medication costs ($47,412.50 vs $52,761.50, 95% CI: 801.5, 9896.40). CONCLUSIONS: While biologic treatments are costly, patients initiating biologics sooner after diagnosis appear to have better HCRU outcomes and require fewer healthcare resources at 1-2 years post-index, potentially leading to overall cost savings.

Amino acid ratio combinations as biomarkers for discriminating patients with pyruvate dehydrogenase complex deficiency from other inborn errors of metabolism.

BACKGROUND: Pyruvate dehydrogenase complex deficiency (PDCD) is a mitochondrial neurometabolic disorder of energy deficit, with incidence of about 1 in 42,000 live births annually in the USA. The median and mean ages of diagnosis of PDCD are about 12 and 31 months, respectively. PDCD is a major cause of primary lactic acidosis with concomitant elevation in blood alanine (Ala) and proline (Pro) concentrations depending on phenotypic severity. Alanine/Leucine (Ala/Leu) ≥4.0 and Proline/Leucine (Pro/Leu) ≥3.0 combination cutoff from dried blood spot specimens was used as a biomarker for early identification of neonates/infants with PDCD. Further investigations were needed to evaluate the sensitivity (SN), specificity (SP), and clinical utility of such amino acid (AA) ratio combination cutoffs in discriminating PDCD from other inborn errors of metabolism (IEM) for early identification of such patients. METHODS: We reviewed medical records of patients seen at UPMC in the past 11 years with molecularly or enzymatically confirmed diagnosis. We collected plasma AA analysis data from samples prior to initiation of therapeutic interventions such as total parenteral nutrition and/or ketogenic diet. Conditions evaluated included organic acidemias, primary mitochondrial disorders (MtDs), fatty acid oxidation disorders (FAOD), other IEMs on current newborn screening panels, congenital cardiac great vessel anomalies, renal tubular acidosis, and non-IEMs. The utility of specific AA ratio combinations as biomarkers were evaluated using receiver operating characteristic curves, correlation analysis, principal component analysis, and cutoff SN, SP, and positive predictive value determined from 201 subjects with broad age range. RESULTS: Alanine/Lysine (Ala/Lys) and Ala/Leu as well as (Ala + Pro)/(Leu + Lys) and Ala/Leu ratio combinations effectively discriminated subjects with PDCD from those with other MtDs and IEMs on current newborn screening panels. Specific AA ratio combinations were significantly more sensitive in identifying PDCD than Ala alone or combinations of Ala and/or Pro in the evaluated cohort of subjects. Ala/Lys ≥3.0 and Ala/Leu ≥5.0 as well as (Ala + Pro)/(Leu + Lys) ≥2.5 and Ala/Leu ≥5.0 combination cutoffs identified patients with PDCD with 100% SN and ~85% SP. CONCLUSIONS: With the best predictor of survival and positive cognitive outcome in PDCD being age of diagnosis, PDCD patients would benefit from use of such highly SN and SP AA ratio combination cutoffs as biomarkers for early identification of at-risk newborns, infants, and children, for early intervention(s) with known and/or novel therapeutics for this disorder.

Placebo effect in randomized controlled trials for Meniere's disease: A meta-analysis.

PURPOSE: Meniere's Disease is a condition known for its recurrent vertigo, fluctuating sensorineural hearing loss, aural fullness, and tinnitus. Previous studies have demonstrated significant influence of placebo treatments. Our objective was to quantify the magnitude of the placebo effect in randomized controlled trials for Meniere's Disease. MATERIALS AND METHODS: A systematic review was performed by searching PubMed, SCOPUS, CINAHL, and Cochrane databases from inception through September 27, 2022. Data extraction, quality rating, and risk of bias assessment were performed by two independent reviewers. A meta-analysis of mean differences with 95 % confidence interval, weighted summary proportions, and proportion differences were calculated using random and fixed effects models. RESULTS: A total of 15 studies (N = 892) were included in the review. Significant improvement was seen in the functional level scores of the pooled placebo groups, with a mean difference of -0.6 points, (95%CI: -1.2 to -0.1). There was no difference in pure tone audiometry, speech discrimination score, or vertigo frequency at 1 and 3 months for the placebo group. Patient-reported vertigo episodes were improved in 52.5 % (95%CI: 39.2 to 65.5) of the placebo group and was significantly less than the pooled experimental group (90.1 %, 95%CI: 39.2 to 65.5, p < 0.001). CONCLUSIONS: The placebo effect in Meniere's Disease trials is associated with some symptomatic improvement in subjective outcomes, such as patient reported vertigo episodes. However, the clinical significance is questionable across other outcomes measures, especially when analyzing objective data. The extent and strength of the placebo effect continues to be a hurdle in the search for better treatment options.

A cluster investigation of Candida auris among hospitalized incarcerated patients.

Objective: Investigate and mitigate a cluster of Candida auris cases among incarcerated patients in a maximum-security prison hospital utilizing contact tracing, screening, whole genome sequencing, and environmental sampling and decontamination. Design: Outbreak investigation. Setting: Inpatient prison hospital affiliated with an academic tertiary referral center. Patients: Inmates of the Texas Department of Criminal Justice. Methods: Epidemiologic and environmental investigations were conducted including contact tracing, point prevalence surveys, and environmental sampling. Whole genome sequencing was performed on positive patient isolates. Results: Following a clinical case of C. auris fungemia, 344 patients underwent C. auris surveillance screening. Eight (2.3%) patients were identified with C. auris colonization. All patients were male. Our index patient was the only clinical case and death. Whole genome sequencing was performed on the nine patient isolates. All isolates were clade III (Africa) and clustered together with the largest SNP difference being 21. Environmental cultures from 7 of 61 rooms (11.5%) were positive following terminal disinfection with bleach. Sites nearest to the patient were most often positive including the hospital bed rails and bedside table. The transmission cluster was successfully mitigated within 60 days of identification. Conclusions: Implementation of an aggressive surveillance and decontamination program resulted in mitigation of a C. auris transmission cluster among our incarcerated patients. This investigation provides valuable insight into C. auris transmission in the incarcerated population, which is not considered a classic high-risk population as well as the challenges faced to stop transmission in a facility that requires the use of shared patient environments.

Rectal Urgency Among Patients With Ulcerative Colitis or Crohn's Disease: Analyses from a Global Survey.

Background: Rectal urgency is a common but under-reported inflammatory bowel disease (IBD) symptom. The present study assessed the prevalence of rectal urgency and its association with disease activity and patient-reported outcomes (PROs) among patients with ulcerative colitis (UC) or Crohn's disease (CD) in a real-world setting. Methods: Data were drawn from the 2017-2018 Adelphi IBD Disease Specific Programme™, a multi-center, point-in-time survey of gastroenterologists and consulting adult patients with UC or CD in France, Germany, Italy, Spain, the United Kingdom, and the United States. Gastroenterologists completed patient record forms and patients completed self-reported forms. Analyses were conducted separately for patients with UC or CD. Patient demographics, clinical characteristics, disease activity, symptoms, and PROs were compared between patients with and without rectal urgency. Results: In total, 1057 patients with UC and 1228 patients with CD were included. Rectal urgency was reported in 20.2% of patients with UC and 16.4% with CD. Patients with rectal urgency were more likely to have moderate or severe disease (UC or CD: P < .0001), higher mean Mayo score (UC: P < .0001), higher mean Crohn's Disease Activity Index score (CD: P < .0001), lower Short IBD Questionnaire scores (UC or CD: P < .0001), and higher work impairment (UC: P < .0001; CD: P = .0001) than patients without rectal urgency. Conclusions: Rectal urgency is a common symptom associated with high disease activity, decreased work productivity, and worse quality of life. Further studies are needed to include rectal urgency assessment in routine clinical practice to better gauge disease activity in patients with UC or CD.

A Bayesian maximum entropy model for predicting tsetse ecological distributions.

BACKGROUND: African trypanosomiasis is a tsetse-borne parasitic infection that affects humans, wildlife, and domesticated animals. Tsetse flies are endemic to much of Sub-Saharan Africa and a spatial and temporal understanding of tsetse habitat can aid surveillance and support disease risk management. Problematically, current fine spatial resolution remote sensing data are delivered with a temporal lag and are relatively coarse temporal resolution (e.g., 16 days), which results in disease control models often targeting incorrect places. The goal of this study was to devise a heuristic for identifying tsetse habitat (at a fine spatial resolution) into the future and in the temporal gaps where remote sensing and proximal data fail to supply information. METHODS: This paper introduces a generalizable and scalable open-access version of the tsetse ecological distribution (TED) model used to predict tsetse distributions across space and time, and contributes a geospatial Bayesian Maximum Entropy (BME) prediction model trained by TED output data to forecast where, herein the Morsitans group of tsetse, persist in Kenya, a method that mitigates the temporal lag problem. This model facilitates identification of tsetse habitat and provides critical information to control tsetse, mitigate the impact of trypanosomiasis on vulnerable human and animal populations, and guide disease minimization in places with ephemeral tsetse. Moreover, this BME analysis is one of the first to utilize cluster and parallel computing along with a Monte Carlo analysis to optimize BME computations. This allows for the analysis of an exceptionally large dataset (over 2 billion data points) at a finer resolution and larger spatiotemporal scale than what had previously been possible. RESULTS: Under the most conservative assessment for Kenya, the BME kriging analysis showed an overall prediction accuracy of 74.8% (limited to the maximum suitability extent). In predicting tsetse distribution outcomes for the entire country the BME kriging analysis was 97% accurate in its forecasts. CONCLUSIONS: This work offers a solution to the persistent temporal data gap in accurate and spatially precise rainfall predictions and the delayed processing of remotely sensed data collectively in the - 45 days past to + 180 days future temporal window. As is shown here, the BME model is a reliable alternative for forecasting future tsetse distributions to allow preplanning for tsetse control. Furthermore, this model provides guidance on disease control that would otherwise not be available. These 'big data' BME methods are particularly useful for large domain studies. Considering that past BME studies required reduction of the spatiotemporal grid to facilitate analysis. Both the GEE-TED and the BME libraries have been made open source to enable reproducibility and offer continual updates into the future as new remotely sensed data become available.

Evaluating Prenatal Diagnostic Imaging for Micrognathia: A Systematic Review and Meta-Analysis.

OBJECTIVE: Studies evaluating the ability to diagnose and accurately predict the severity of micrognathia prenatally have yielded inconsistent results. This review aimed to evaluate reliability of prenatal diagnostic imaging in the diagnosis and characterization of micrognathia. DESIGN: Systematic review and meta-analysis. SETTING: Studies with a prenatal diagnosis of micrognathia via ultrasound with a confirmatory postnatal examination were included. Prenatal severity was defined with and without mandibular measurements. Extent of airway obstruction at birth was defined by level of intervention required. Meta-analyses of proportions and relative risk were performed. PATIENTS: A total of 16 studies with 2753 neonates were included. MAIN OUTCOME MEASURES: Primary outcome was the efficacy of characterizing the degree of micrognathia on prenatal imaging as it relates to respiratory obstruction at birth. Secondary outcome was the accuracy of prenatal diagnosis with the utilization of mandibular measurements versus without. RESULTS: Performing meta-analysis of proportions, the proportion of missed prenatal diagnoses of micrognathia made without mandibular measurements was 11.62% (95%CI 2.58-25.94). Utilizing mandibular measurements, the proportion of cases missed were statistically lower (0.20% [95%CI 0.00-0.70]). Patients determined to have severe micrognathia by prenatal imaging did not have a statistically significant increase in risk for more severe respiratory obstruction at birth (RR 3.13 [95%CI 0.59-16.55], P = .180). CONCLUSION: The proportion micrognathia cases missed when prenatal diagnosis was made without mandibular measurements was over 1 in 10, with mandibular measures improving accuracy. This study highlights the need for a uniform objective criterion to improve prenatal diagnosis and planning for postnatal care.

Aberrant Left Colic Artery and Accessory Right Colic Artery: A Case Report and Surgical Implications.

During a routine dissection of the abdominal region in our department of anatomy's dissection laboratory, we found two variations of the vasculature of the gastrointestinal tract within the greater peritoneal and retroperitoneal compartments: an aberrant left colic artery (LCA) and an accessory right colic artery (RCA). The aberrant LCA originates from a common trunk (CT) that arises from the superior mesenteric artery instead of the inferior mesenteric artery. The CT continues for a short distance and terminates by dividing into a middle colic artery and an accessory RCA. The aberrant LCA and accessory RCA had abnormal courses; therefore, they are vulnerable to injury during surgical procedures of the region. Hence, a thorough knowledge of vascular variations is required to avoid potential complications.

The Lack of Standardized Outcomes for Surgical Salvage of HPV-Positive Recurrent Oropharyngeal Squamous Cell Carcinoma: A Systematic Scoping Review.

Although HPV status is known to provide an improved prognosis in initial treatments of HPV-positive oropharyngeal squamous cell carcinoma (OPSCC), it is unclear how it affects patients who receive salvage surgery (SS), which has historically poor survival rates. The purpose of this study was to evaluate the role of SS for patients with locoregional recurrence (LRR) of HPV-positive OPSCC and its impact survival rates. We conducted a scoping review of literature through October 2022 and included 995 individuals. Survival endpoints, such as overall survival (OS), Kaplan-Meier curves, and median post-recurrence survival, were analyzed in addition to demographics. Of all studies, 18.8% (6/32) reported any survival data for SS patients, with the most prevalent reporting 2- and 5-year OS in two studies. Median post-recurrence survival was not reported for SS. These findings reveal the limited and unpredictable reporting of survival-specific data on SS for HPV-positive OPSCC. With limited survival assessment, it is difficult to assess the potential advantages and disadvantages of this therapy to guide clinical decision-making.

Teaching children to identify and avoid food allergens using behavioral skills training.

Allergic reactions to allergenic foods can pose a lethal threat to children with food allergies. Previous research has demonstrated the effectiveness of using behavioral skills training (BST) plus in situ training (IST) to teach safety responses to children. However, there has not been an evaluation of using BST to teach food safety to children with food allergies. Three elementary-school children of neurotypical development with food allergies participated. We evaluated the efficacy of BST with IST in teaching participants to identify and respond to allergenic foods by (a) asking to see the food packaging, (b) scanning the food label for the allergenic food, and (c) reporting the safety threat to an adult while not consuming the food. Trials without allergenic foods were also presented to ensure discriminated responding. All participants demonstrated the three correct safety responses after BST and responded differentially across allergenic and nonallergenic foods, with two participants requiring feedback (IST).
