Feline Forensics: Revealing the Unique Decomposition of Cats.

Limited data about the differences between the decomposition of animals with fur exist within the forensic veterinary medicine discipline. Due to the sheer number of animals used as animal models and the number of animals that exist, determining stages of decomposition that are applicable for all species is difficult. Typically, assessing what stage of decomposition a decedent is in is subjective due to the visual assessment of decomposition changes.

Meigen (Diptera: Calliphoridae) Is a Primary Colonizer of Domestic Cats ().

Meigen (Diptera: Calliphoridae) is widespread throughout North America and Europe. Described in 1826, this blow fly was quickly associated with myiasis in amphibians, and to date has rarely been reported in carrion. There is limited data regarding the time of colonization of animals with fur and the interpretation of this data is difficult due to variation in the animal models used.

Initial blow fly (Diptera: Calliphoridae) colonization of cats (Felis catus) in Indiana.

Many disciplines are utilized within the field of veterinary forensic sciences, including forensic entomology. Understanding the initial colonization period by flies of forensic importance can contribute to estimating the minimum postmortem interval. There is limited data regarding the time of colonization of animals with fur, and the interpretation of this data is difficult due to the variation in animal models used.

Impact of Early Direct Patient Notification on Follow-Up Completion for Nonurgent Actionable Incidental Radiologic Findings.

Purpose: The aim of this study was to evaluate whether early direct patient notification in addition to an existing multistage recommendation-tracking system (Backstop) increases follow-up completion rates for actionable incidental findings (AIFs). Patient attitudes toward early notification were also assessed.

Methods: This prospective, randomized controlled trial recruited patients with AIFs requiring follow-up being enrolled into the Backstop system.

White Paper: Best Practices in the Communication and Management of Actionable Incidental Findings in Emergency Department Imaging.

Purpose: Actionable incidental findings (AIFs) are common in radiologic imaging. Imaging is commonly performed in emergency department (ED) visits, and AIFs are frequently encountered, but the ED presents unique challenges for communication and follow-up of these findings. The authors formed a multidisciplinary panel to seek consensus regarding best practices in the reporting, communication, and follow-up of AIFs on ED imaging tests.

Effects of Leg Length, Sex, Laterality, and the Intermediate Femoral Cutaneous Nerve on Infrapatellar Innervation.

Background: An iatrogenic injury to the infrapatellar branch of the saphenous nerve (IPBSN) is a common precipitant of postoperative knee pain and hypoesthesia.

Purpose: To locate potential safe zones for incision by observing the patterns and pathway of the IPBSN while examining the relationship of its location to sex, laterality, and leg length.

Study Design: Descriptive laboratory study.

Comorbid Patterns in the Homeless Population: A Theoretical Model to Enhance Patient Care.

Introduction: From the perspective of social determinants, homelessness perpetuates poor health and creates barriers to effective chronic disease management, necessitating frequent use of emergency department (ED) services. In this study we developed a screening algorithm (checklist) from common comorbidities observed in the homeless population in the United States. The result was a theoretical screening tool (checklist) to aid healthcare workers in the ED, including residents, medical students, and other trainees, to provide more efficacious treatment and referrals for discharge.

Biodiversity of Forensically Relevant Blowflies (Diptera: Calliphoridae) at the Anthropology Research Facility in Knoxville, Tennessee, USA.

Understanding the biodiversity and distribution of forensically relevant blowflies (Diptera: Calliphoridae) in a region can aid in legal investigations when insects are associated with remains. For this purpose, we conducted a 14-month-long blowfly survey at the Anthropology Research Facility (ARF) of the University of Tennessee in Knoxville, Tennessee. Traps baited with pork kidney were deployed for 24 h twice a month throughout the study.

Impact of Comingled Heterospecific Assemblages on Developmentally Based Estimates of the Post-Mortem Interval-A Study with (Meigen), (Meigen) and Robineau-Desvoidy (Diptera: Calliphoridae).

Estimates of the minimum post-mortem interval (mPMI) using the development rate of blow flies (Diptera: Calliphoridae) are common in modern forensic entomology casework. These estimates are based on single species developing in the absence of heterospecific interactions. Yet, in real-world situations, it is not uncommon to have 2 or more blow fly species developing on a body.

An Analysis of Forensically Important Insects Associated with Human Remains in Indiana, U.S.A.

Research documenting insect colonization of human remains is limited in North America, and currently nonexistent for the American Midwest. Such research is essential for forensic entomologists to identify species of research interest in a region. In this study, we collected insects from human remains in 24 cases across Indiana from June 2016 through September 2018.

Combined wear and ageing of ceramic-on-ceramic bearings in total hip replacement under edge loading conditions.

Ceramic-on-ceramic bearings in total hip replacement have shown the potential to provide low wear solutions in hip replacement. Assessing the tribological performance of these materials is important to predict their long-term performance in patients. In this study, a methodology was devised to assess the tribological in vitro behaviour of composite ceramics under combined adverse edge loading conditions and accelerated ageing.

Effect of Temperature on Oviposition Behavior and Egg Load of Blow Flies (Diptera: Calliphoridae).

Making optimal oviposition decisions is especially important for female carrion colonizing insects whose larvae often depend on ephemeral resources. Optimal oviposition theory predicts that females should exhibit behaviors that will maximize the performance of their offspring. Oviposition can be influenced by a variety of factors, including temperature.

Sub-surface assessment of hydrothermal ageing in zirconia-containing femoral heads for hip joint applications.

Unlabelled: Zirconia-based materials have been used in orthopaedics since the 1980s, with large success, mainly thanks to transformation toughening. On the other hand, their main drawback is their potential sensitivity to hydrothermal ageing, i.e.

Potential discrepancy between plain films and CT scans in Brooker classification of heterotopic ossification.

Objectives: The Brooker classification is a commonly used tool to characterize the extent of heterotopic ossification (HTO), which is the dystrophic formation of mature lamellar bone in non-osseous tissues such as muscles, connective tissue or nerves. We aim to provide illustrative cases to describe the limitations and challenges of this system.

Methods: A retrospective review was conducted in all patients who had retrieved hip and/or pelvic radiotherapy for HTO prophylaxis at Sunnybrook Health Sciences Centre between July 1998 and August 2016.

The Relationship Between Surface Area and Volume of Common Blow Fly (Diptera: Calliphoridae) Oviposition Sites and Carrion Body Mass.

Female blow flies (Diptera: Calliphoridae) demonstrate site preferences when ovipositing on carrion. Preference for oviposition sites is believed to reflect the suitability of the site such that the most preferred locations provide offspring with the greatest chance of survival. A number of factors might influence female choice, including area available for oviposition.

Microfluidic droplet-based liquid-liquid extraction and on-chip IR spectroscopy detection of cocaine in human saliva.

We present a portable microsystem to quantitatively detect cocaine in human saliva. In this system, we combine a microfluidic-based multiphase liquid-liquid extraction method to transfer cocaine continuously from IR-light-absorbing saliva to an IR-transparent solvent (tetrachloroethylene) with waveguide IR spectroscopy (QC-laser, waveguide, detector) to detect the cocaine on-chip. For the fabrication of the low-cost polymer microfluidic chips a simple rapid prototyping technique based on Scotch-tape masters was further developed and applied.

Infrared attenuated total reflection (IR-ATR) spectroscopy for detecting drugs in human saliva.

The consumption of drugs is of great concern worldwide. Various drug tests for humans have been developed but there is no compact and easy-to-use test device available yet for direct semi-quantitative drug testing in the field. We suggest using attenuated total reflection (ATR) infrared spectroscopy as a sensing method to analyze human saliva samples with respect to drugs.

The phytochemical piceatannol induces the loss of CBL and CBL-associated proteins.

Piceatannol is a naturally occurring bioactive stilbene with documented antileukemic properties. It has been extensively used as a Syk-selective protein tyrosine kinase inhibitor for the study of various signaling pathways. Herein, we show that the hydroxystilbene, piceatannol, and related catechol ring-containing compounds are able to induce the loss of the Cbl family of proteins.

Tissue procurement for molecular studies using laser-assisted microdissection.

Properly collected and stored human specimens offer the unique opportunity to study human diseases at the molecular level in the real in vivo situation. The intention of this chapter is, first, to raise the awareness for important points, which have to be clarified before human tissue samples are collected and stored for molecular studies. Second, detailed protocols are provided for the fixation and processing of bone marrow trephines and the isolation of morphologically and immunohistochemically defined pure cell populations from bone marrow trephine sections using laser-assisted microdissection.

Background: Topotecan is an active drug in small-cell lung cancer (SCLC). In our previous study, a combination of topotecan with cisplatin was associated with a median overall survival of 7.6 or 8.

Phase III study of second-line chemotherapy for advanced non-small-cell lung cancer with weekly compared with 3-weekly docetaxel.

Purpose: A phase III study to determine whether a weekly docetaxel schedule improves the therapeutic index compared with the classic 3-weekly schedule.

Patients And Methods: Patients with stage IIIB-IV non-small-cell lung cancer (NSCLC) were randomly assigned to docetaxel 75 mg/m2 on day 1 every 3 weeks (3-weekly) and 35 mg/m2 on days 1, 8, and 15 (weekly) for < or = eight cycles. End points included survival (primary), toxicity, and response.

Anxiety, depression and smoking in schoolchildren--implications for smoking prevention.

The prevalence of smoking among 14 to 18-year-old adolescents (one out of three) is as high as in the general population in Hungary. Depression and anxiety disorders are also major public health problems. Our objective was to investigate the correlations between smoking status and anxiety and depressive symptoms, as well as to identify potential implications for the prevention of nicotine dependence.

[Acute compartment syndrome of the foot].

In two patients, a girl aged 2 and a man aged 52 years, who had suffered a severe crush trauma, acute compartment syndrome of the foot was diagnosed. Decompression by means of one medial and two dorsal dermato-fasciotomy incisions was carried out and fractures of the metatarsals were repaired using K-wires. The girl recovered completely, but the man developed progressive necrosis in the flexors of the foot and on the skin on the foot sole which necessitated amputation of the foot.
