A comparison of risk factor investigation and experts' opinion elicitation analysis for identifying foot-and-mouth disease (FMD) high-risk areas within the FMD protection zone of South Africa (2007-2016).

Foot-and-mouth disease is a controlled disease in accordance with the South African Animal Diseases Act (Act 35 of 1984). The country was classified by the World Organisation for Animal Health (WOAH) as having a FMD free zone without vaccination in 1996. However, this status was suspended in 2019 due to a FMD outbreak outside the controlled zones.

Intramedullary spinal cord metastasis treated with prophylactic laminoplasty prior to radiation to the spinal cord: a case report.

Background: A cervical laminoplasty is a surgical procedure used to treat moderate-to-severe cervical stenosis resulting in cervical myelopathy. It is performed to widen the spinal canal and reduce compression on the spinal cord and surrounding nerves. Though often performed electively on patients presenting with varying degrees of neurologic dysfunction including weakness and imbalance, it may also be used prophylactically when spinal cord inflammation or edema is anticipated.

Optimization of a foot-and-mouth disease virus Southern African Territories-specific solid-phase competitive ELISA for small ruminant serum samples.

We optimized and verified a single-spot solid-phase competitive ELISA (ss-SPCE) to detect antibodies against structural proteins of Southern African Territories (SAT) serotypes of foot-and-mouth disease virus (FMDV) in small ruminants. Sera from goats vaccinated and experimentally challenged with a SAT1 FMDV pool were tested in duplicate at 4 dilutions (1:10, 1:15, 1:22.5, 1:33.

Sustained Clinical Benefits of Spiration Valve System in Patients with Severe Emphysema: 24-Month Follow-Up of EMPROVE.

Follow-up of patients with emphysema treated with endobronchial valves is limited to 3-12 months after treatment in prior reports. To date, no comparative data exist between treatment and control subjects with a longer follow-up. To assess the durability of the Spiration Valve System (SVS) in patients with severe heterogeneous emphysema over a 24-month period.

Abundance does not predict extinction risk in the fossil record of marine plankton.

A major premise of ecological neutral theory is that population size is inversely related to extinction risk. This idea is central to modern biodiversity conservation efforts, which often rely on abundance metrics to partially determine species extinction risk. However, limited empirical studies have tested whether extinction is indeed more probable for species with low abundances.

High risk lung nodule: A multidisciplinary approach to diagnosis and management.

Pulmonary nodules are often discovered incidentally during CT scans performed for other reasons. While the vast majority of nodules are benign, a small percentage may represent early-stage lung cancer with the potential for curative treatments. With the growing use of CT for both clinical purposes and lung cancer screening, the number of pulmonary nodules detected is expected to increase substantially.

Redefining the Classification for Bertolotti Syndrome: Anatomical Findings in Lumbosacral Transitional Vertebrae Guide Treatment Selection.

Objective: We present the Jenkins classification for Bertolotti syndrome or symptomatic lumbosacral transitional vertebra (LSTV) and compare this with the existing Castellvi classification for patients presenting for treatment.

Methods: We performed a retrospective cohort study of 150 new patients presenting for treatment of back, hip, groin, and/or leg pain from July 2012 through February 2022. Using magnetic resonance imaging, computed tomography, and radiography, the patients with a radiographic finding of LSTV, an appropriate clinical presentation, and identification of LSTV as the primary pain generator via diagnostic injections were diagnosed with Bertolotti syndrome.

Redefining the Treatment of Lumbosacral Transitional Vertebrae for Bertolotti Syndrome: Long-Term Outcomes Utilizing the Jenkins Classification to Determine Treatment.

Objective: Using the Jenkins classification, we propose a strategy of shaving down hypertrophic bone, unilateral fusion, or bilateral fusion procedures to achieve pain reduction and improve quality of life for patients with Bertolotti syndrome.

Methods: We reviewed 103 patients from 2012 through 2021 who had surgically treated Bertolotti syndrome. We identified 56 patients with Bertolotti syndrome and at least 6 months of follow-up.

Factors associated with foot-and-mouth disease seroprevalence in small ruminants and identification of hot-spot areas in northern Nigeria.

Many small ruminants infected with foot-and-mouth disease (FMD) remain asymptomatic, with the capacity to promote silent viral spread within domestic and wildlife species. However, little is known about the epidemiological role played by small ruminants in FMD. In particular, there are few studies that examine FMD seroprevalence, spatial patterns and risk factors for exposure in small ruminants.

Evaluating safe time to discharge after closed reduction and percutaneous pinning of uncomplicated type III supracondylar humerus fractures: a single-center retrospective review.

The purpose of this retrospective study was to review complications following closed reduction, percutaneous pinning of isolated, type III supracondylar fractures without associated injuries to evaluate if patients may be discharged safely on the day of surgery. We performed a retrospective chart and radiographic review of patients with isolated Gartland type III supracondylar humerus fractures who underwent closed reduction and percutaneous pinning over a 4-year period. We reviewed admission time to the emergency department, time and length of surgery, time to discharge, postoperative complications, readmission rate and office visits.

A novel two-layer, intradural and extradural patch graft approach to treating dural defects and tears: illustrative case.

Background: Dural tears must be quickly addressed to avoid the development of positional headaches and pseudomeningoceles, among other complications. However, sizeable areas of friable or absent dura create unique challenges when attempting to achieve a watertight seal. We have developed a two-layer subdural and epidural fibrous patch technique to treat expansive or challenging dural tears as a result of our experience treating spinal fluid leaks.

Late Neogene Lophophaenidae (Nassellaria, Radiolaria) from the eastern equatorial Pacific.

Lophophaenidae is a clade of polycystine radiolarians that was highly abundant and diverse in the Late NeogeneRecent eastern equatorial Pacific (EEP). Despite their importance in fossil plankton assemblages, lophophaenids have been neglected because of their generally small size, complex morphology, and weak taxonomic framework. These challenges have left many lophophaenid concepts poorly defined or lacking formal description.

Therapeutic bronchoscopy for malignant central airway obstruction: impact on quality of life and risk-benefit analysis.

Purpose Of Review: Malignant central airway obstruction (CAO) is a common complication in cancer and confers significant symptom burden and reduction in quality of life. Multiple bronchoscopic interventions exist for malignant CAO. In this review, we discuss the role of therapeutic bronchoscopy in the management of malignant CAO, emphasizing its impact on symptom control and quality of life while balancing the risks and benefits of intervention.

Update on the diagnosis and management of malignant pleural effusions.

Roughly 150,000 malignant pleural effusions (MPE) are diagnosed in the United States each year. The majority of cases are caused by lung and breast cancer, and since MPE represents advanced disease, the prognosis is generally poor. In this article we review the pathophysiology, epidemiology, and prognosis of MPE.

Triton, a new species-level database of Cenozoic planktonic foraminiferal occurrences.

Planktonic foraminifera are a major constituent of ocean floor sediments, and thus have one of the most complete fossil records of any organism. Expeditions to sample these sediments have produced large amounts of spatiotemporal occurrence records throughout the Cenozoic, but no single source exists to house these data. We have therefore created a comprehensive dataset that integrates numerous sources for spatiotemporal records of planktonic foraminifera.

Marine plankton show threshold extinction response to Neogene climate change.

Ongoing climate change is predicted to trigger major shifts in the geographic distribution of marine plankton species. However, it remains unclear whether species will successfully track optimal habitats to new regions, or face extinction. Here we show that one significant zooplankton group, the radiolaria, underwent a severe decline in high latitude species richness presaged by ecologic reorganization during the late Neogene, a time of amplified polar cooling.

Complex Circulation of Foot-and-Mouth Disease Virus in Cattle in Nigeria.

Nigeria is a large densely populated country in West Africa. Most of its livestock is raised in a pastoralist production system with typical long distance migration in search of water and feed. As the demand for animal products largely exceeds the domestic production, large numbers of livestock are imported from neighboring countries without sanitary restrictions.

Efficacy of a foot-and-mouth disease vaccine against a heterologous SAT1 virus challenge in goats.

Goats are susceptible to infection with foot-and-mouth disease virus (FMDV), but their role in the epidemiology of the disease and response to vaccination is poorly understood. In southern Africa, FMDV serotypes Southern African Territories (SAT) 1, 2 and 3 are known to be endemic. In this study, we evaluated the efficacy of a pentavalent FMD vaccine in goats against heterologous challenge with a pool of field SAT1 FMDV.

Impact of foot-and-mouth-disease on goat behaviour after experimental infection with serotype SAT1 virus.

Infectious diseases and parasitic infestations can cause a set of non-specific clinical signs, such as increased body temperature and resting, and a decrease in food intake. These physiological and behavioural changes have an adaptive function facilitating defences against the pathogen and to support immune functions. These so-called' sickness behaviours' can also be used as an early detection tool for disease.

Lung Cancer Heterogeneity in Modulation of Th17/IL17A Responses.

The interplay between tumors and their immune microenvironment is critical for cancer development and progression. The discovery of tumor heterogeneity has provided a window into a complex interplay between tumors, their secreted products, and host immune responses at the cellular and molecular levels. Tumor heterogeneity can also act as a driving force in promoting treatment resistance and correlates with distinct tumor-mediated acquired immune responses.

Characterization of transboundary foot-and-mouth disease viruses in Nigeria and Cameroon during 2016.

Continuous surveillance for foot-and-mouth disease (FMD) in endemic settings such as West Africa is imperative to support improved local and regional control plans, with the long-term goal of regional eradication. This paper describes the genetic characterization of FMD viruses (FMDV) obtained from outbreaks in Nigeria (n = 45) and Cameroon (n = 15) during 2016 and from archival samples (n = 3) retrieved from a 2014 outbreak in Nigeria. These viruses were analysed in the context of previously published FMDV sequences from the region.
