Wheat price hikes and food security in Sub-Saharan Africa.

The Russia–Ukraine conflict affected the price of staple crops and spurred interest in tropical wheat production. Regional consumption patterns and trade are better placed to guide effective and sustainable food security policy strategies.

Impacts of COVID-19 on global poverty, food security, and diets: Insights from global model scenario analysis.

This study assesses the impact of coronavirus disease 2019 (COVID-19) on poverty, food insecurity, and diets, accounting for the complex links between the crisis and the incomes and living costs of vulnerable households. Key elements are impacts on labor supply, effects of social distancing, shifts in demand from services involving close contact, increases in the cost of logistics in food and other supply chains, and reductions in savings and investment. These are examined using IFPRI's global general equilibrium model linked to epidemiological and household models.

The COVID-19 crisis will exacerbate maternal and child undernutrition and child mortality in low- and middle-income countries.

The economic crisis and food and health system disruptions related to the COVID-19 pandemic threaten to exacerbate undernutrition in low- and middle-income countries (LMICs). We developed pessimistic, moderate and optimistic scenarios for 2020-2022 and used three modelling tools (MIRAGRODEP, the Lives Saved Tool and Optima Nutrition) to estimate the impacts of pandemic-induced disruptions on child stunting, wasting and mortality, maternal anaemia and children born to women with a low body mass index (BMI) in 118 LMICs. We estimated the cost of six nutrition interventions to mitigate excess stunting and child mortality due to the pandemic and to maximize alive and non-stunted children, and used the human capital approach to estimate future productivity losses.

COVID-19 pandemic leads to greater depth of unaffordability of healthy and nutrient-adequate diets in low- and middle-income countries.

Unaffordability of healthy diets affected 3 billion people before the COVID-19 pandemic, 2.5 billion of whom lived in 63 low- and middle-income countries. In these 63 countries, income losses due to the pandemic have markedly worsened the affordability gap.

Agricultural subsidies and global greenhouse gas emissions.

Agricultural production is strongly affected by and a major contributor to climate change. Agriculture and land-use change account for a quarter of total global emissions of greenhouse gases (GHG). Agriculture receives around US$600 billion per year worldwide in government support.

N,S,O-Heterocycles in Aged Champagne Reserve Wines and Correlation with Free Amino Acid Concentrations.

Champagne regulations allow winegrowers to stock still wines to compensate for quality shifts in vintages, mainly due to climate variations. According to their technical requirements and house style, Champagne producers use these stored wines in their blends to enhance complexity. The presence of lees and aging at low pH (2.

Intracranial metastatic neuroblastoma treated with gamma knife stereotactic radiosurgery: report of two novel cases.

Intracranial metastasis of neuroblastoma (IMN) is associated with poor survival. No curative therapy for the treatment of IMN currently exists. Unfractionated radiotherapy may be beneficial in the treatment of IMN given the known radiosensitivity of neuroblastoma as well as its proclivity to metastasize as discrete lesions.

Feasibility of disaster mental health preparedness training for black communities.

Objectives: To test the feasibility of developing evidence-based mental health training to build capacity to respond to natural disasters in black communities and the adaptation of a train-the-trainer (TTT) model for black community leaders and clinical providers in distressed areas at risk of natural disasters.

Methods: A core curriculum was developed based on a training needs assessment and resource review. Participants were recruited using network sampling in eastern North Carolina.

Concept and development of a discharge alert filter for abnormal laboratory values coupled with computerized provider order entry: a tool for quality improvement and hospital risk management.

Purpose: To develop a clinical decision support system activated at the time of discharge to reduce potentially inappropriate discharges from unidentified or unaddressed abnormal laboratory values.

Methods: We identified 106 laboratory tests for possible inclusion in the discharge alert filter. We selected 7 labs as widely available, commonly obtained, and associated with high risk for potential morbidity or mortality within abnormal ranges.

Anchoring depth electrodes for bedside removal: a "break-away" suturing technique for intracranial monitoring.

Background: Intracranial depth electrodes for epilepsy are easily dislodged during long-term monitoring unless adequately anchored, but a technique is not available that is both secure and allows easy explantation without reopening the incision.

Objective: To describe a convenient and inexpensive method for anchoring depth electrodes that prevents migration and incidental pullout while allowing electrode removal at the bedside.

Methods: An easily breakable suture (eg, MONOCRYL) is tied around both the depth electrode and a heavy nylon suture and anchored to a hole at the edge of the burr hole; the tails of both are tunneled together percutaneously.

Aneurysm of a duplicate middle cerebral artery.

Background: Anatomic middle cerebral artery (MCA) anomalies are rare, but each of the described variants (eg, duplicate, fenestrated, accessory) can be of clinical significance.

Case Description: A 34-year-old man with a history of left hemispheric stroke was found to have an aberrant, early-arising duplicate left M1 segment of the MCA with an associated asymptomatic fusiform aneurysm. The patient was treated with a superficial temporal artery (STA) to distal MCA bypass followed by surgical trapping of the aneurysm.

Assessment of training needs for disaster mental health preparedness in black communities.

Reducing racial disparities in postdisaster mental health requires the integration of unique and complex community challenges in disaster planning. We conducted focus group discussions with 13 community leaders and 7 clinical providers in eastern North Carolina to inform the adaptation of a competency-based training model in postdisaster mental health for black communities. The audience-specific perspectives on disaster mental health and training priorities were identified by structured thematic analyses.

A framework for assessing patient crossover and health information exchange value.

Objective: To evaluate the benefit of a health information exchange (HIE) between hospitals, we examine the rate of crossover among neurosurgical inpatients treated at Emory University Hospital (EUH) and Grady Memorial Hospital (GMH) in Atlanta, Georgia. To inform decisions regarding investment in HIE, we develop a methodology analyzing crossover behavior for application to larger more general patient populations.

Design: Using neurosurgery inpatient visit data from EUH and GMH, unique patients who visited both hospitals were identified through classification by name and age at time of visit.

Meningioangiomatosis: a case report and literature review emphasizing diverse appearance on different imaging modalities.

Purpose. Meningioangiomatosis (MA) is a rare, benign lesion that commonly mimics other intracranial malformations in clinical presentation and appearance on imaging. The case presented and the literature review performed highlight the importance of combining MRI and CT results to better characterize intracranial lesions and including MA on the list of differential diagnoses of patients presenting with seizures.

In vivo assay of folate receptors in nonfunctional pituitary adenomas with 99mTc-folate SPECT/CT.

Unlabelled: The objective of this study was to evaluate the in vivo assay of folate receptors in nonfunctional pituitary adenomas using preoperative (99m)Tc-folate SPECT/CT and Western blot analysis (WBA) of surgical specimens as the standard.

Methods: Fifty-six patients (29 men, 27 women; age range, 29-82 y) with clinically nonfunctional pituitary adenomas on MRI underwent preoperative imaging using 666 MBq (18 mCi) of (99m)Tc-folate. SPECT/CT images and whole-body and lateral head planar images were acquired approximately 2 h after injection.

Management of traumatic cervical spondyloptosis in a neurologically intact patient: case report.

Study Design: Case report.

Objective: To review the management of a neurologically intact patient with complete cervical spondyloptosis with particular attention to the role and timing of closed preoperative cervical traction and subsequent stabilization.

Summary Of Background Data: Traumatic cervical spondyloptosis is typically associated with complete and irreversible spinal cord injury.

Folate receptor expression in pituitary adenomas cellular and molecular analysis.

Clinically nonfunctional pituitary adenomas cause hypopituitarism or compression of regional structures. Unlike functional tumors, there is no available medical treatment or specific imaging technique for these tumors. We have recently discovered that both folate receptor (FR)alpha mRNA and protein are uniquely overexpressed in nonfunctional pituitary tumors, but not in functional adenomas.

Pilot test of cooperative learning format for training mental health researchers and black community leaders in partnership skills.

To support reduction of racial disparities in mental health diagnosis and treatment, mental health researchers and black community-based organization (CBO) leaders need training on how to engage in collaborative research partnerships. In this study, we pilot tested a series of partnership skills training modules for researchers and CBO leaders in a collaborative learning format. Two different sets of three modules, designed for separate training of researchers and CBO leaders, covered considering, establishing and managing mental health research partnerships and included instructions for self-directed activities and discussions.

Concentration and detection of caliciviruses in water samples by reverse transcription-PCR.

Human caliciviruses (HuCVs) cause waterborne outbreaks of gastroenteritis. Standard indicators of a safe water supply do not adequately predict contamination of water by viruses, including HuCVs. We developed a method to concentrate and detect HuCVs in water samples by using a cultivable primate calicivirus (Pan-1) as a model.

Repeatability and relationship with field mating performance of a serving capacity pen test in rams.

Two studies were conducted to analyse the repeatability of a serving capacity (SC) pen test and to evaluate the correlation of the results of such a test with field performance. The Laborde SC test, which measures SC by exposing an individual ram for 40min to two restrained non-oestrous ewes in a pen was used. In the first study, SC was measured on four and six occasions during the autumn of 1994 and 1995, respectively.

Detection of pathogen transmission in neonatal nurseries using DNA markers as surrogate indicators.

Objective: Nosocomial infections are a major problem confronting neonatal intensive care units (NICUs). This study was conducted to determine if DNA markers designed from the cauliflower mosaic virus (CaMV 35S DNA) can serve as surrogate indicators of nosocomial pathogen transmission in NICUs.

Methods: Regions of cauliflower CaMV 35S promoter DNA were designed to serve as surrogate markers of microbial transmission pathways.

Estimation of the shear stress on the surface of an aortic valve leaflet.

The limited durability of xenograft heart valves and the limited supply of allografts have sparked interest in tissue engineered replacement valves. A bioreactor for tissue engineered valves must operate at conditions that optimize the biosynthetic abilities of seeded cells while promoting their adherence to the leaflet matrix. An important parameter is shear stress, which is known to influence cellular behavior and may thus be crucial in bioreactor optimization.
