Different perceptions of thorax anatomy and hand placement for chest compressions among healthcare professionals and laypersons: Implications for cardiopulmonary resuscitation.

Resusc Plus 2021 Sep 29;7:100138. Epub 2021 Jun 29.

Department of Clinical Medicine, Faculty of Health, Aarhus University, Aarhus, Denmark.

Aim: The European Resuscitation Council guidelines recommend that the hand position for chest compressions is obtained by "placing the heel of your hand in the centre of the chest". Importantly, guidelines are based on a study on healthcare professionals being extrapolated to laypersons. This study explored whether healthcare professionals and laypersons differ in anatomical knowledge necessary for obtaining the correct hand position for chest compressions and understanding of European Resuscitation Council guideline recommendations in the absence of a demonstration.

Significant Liver Atrophy Due to Vascular Compromise Associated With Adult Congenital Diaphragmatic Hernia.

Cureus 2021 Aug 13;13(8):e17158. Epub 2021 Aug 13.

Transplant Unit, Department of Surgery, Atal Bihari Vajpayee Institute of Medical Sciences (ABVIMS) and Dr. Ram Manohar Lohia Hospital (RMLH), Delhi, IND.

Diaphragmatic hernia in adults is mostly post-traumatic in origin, and rarely congenital. In both situations, the right side is less commonly involved due to the protection offered by the liver and earlier closure of the right pleuroperitoneal canal. A congenital diaphragmatic hernia may present in adulthood with multi-visceral contents, of which the liver is an extremely rare content, mentioned only in a few previous reports. Read More

[Redo Operation for Mediastinal Tumor].

Kyobu Geka 2021 Sep;74(10):839-844

Department of Surgery, Division of Thoracic Surgery, Shimane University Faculty of Medicine, Izumo, Japan.

The mediastinum contains large blood vessels, airways, and spinal cord, which are anatomically important parts of the human body because they survive by injury, obstruction, and compression, and are involved in activities of daily living( ADL). Therefore, even benign tumors have been indicated for aggressive surgical intervention. Dissection procedures from these anatomically important structures is extremely risky and difficult in reoperation for recurrence of mediastinal tumors, so careful consideration and attention must be paid to the surgical indications and methods.

Development and prospective validation of a spatial dose pattern based model predicting acute pulmonary toxicity in patients treated with volumetric arc-therapy for locally advanced lung cancer.

Radiother Oncol 2021 Sep 18. Epub 2021 Sep 18.

Department of Radiation Oncology, University Hospital, Brest, France; LaTIM UMR 1101 INSERM, University Brest, Brest, France.

Introduction: (Chemo)-radiotherapy is the standard treatment for patients with locally advanced lung cancer (LALC) not accessible to surgery. Despite strict application of dose constraints, acute toxicities such as acute pulmonary toxicity (APT) remain frequent, and may impact treatment's compliance and patients' quality of life. Previously, on a population treated with intensity-modulated photon therapy or passive scattering proton therapy, spatial dose patterns associated with APT were identified in the lower lungs, especially in the posterior right lung.

Live Imaging of Myogenesis in Indirect Flight Muscles in .

Authors:
Dagan Segal

Bio Protoc 2017 Jul 5;7(13):e2377. Epub 2017 Jul 5.

Department of Molecular Genetics, Weizmann Institute of Science, Rehovot, Israel.

The indirect flight muscles (IFMs) are the largest muscles in the fly, making up the bulk of the adult thorax. IFMs in are generated during pupariation by fusion of hundreds of muscle precursor cells (myoblasts) with larval muscle templates (myotubes). Prominent features, including the large number of fusion events, the structural similarity to vertebrate muscles, and the amenability to the powerful genetic techniques of the system make the IFMs an attractive system to study muscle cell fusion.

Herzchirurgische Klinik und Poliklinik, Klinikum der LMU, Marchioninistr. 15, 81377 München, Deutschland.

New technologies and continuous further development of extracorporeal support systems have expanded the range of applications of extracorporeal life support (ECLS) in recent years. In addition to use in cardiogenic shock or resuscitation, the number of requests for the transfer of unstable patients from peripheral hospitals are increasing. Organizational challenges such as the establishment of networks and structured team training for all parties involved mean that the ECLS team is quickly available to reach the patient. Read More

Does body size influence mating success? A morphometric study of two (Diptera: Tephritidae) fruit fly species.

Bull Entomol Res 2021 Sep 20:1-13. Epub 2021 Sep 20.

El Colegio de la Frontera Sur (ECOSUR), Carretera Antiguo Aeropuerto, C.P. 30700, Tapachula, Chiapas, México.

Male mating success depends on various traits and factors, and correctly identifying these traits can be key in the context of pest management. For tephritid pests, controlled through the sterile insect technique (SIT) traits, such as male size, can be manipulated through mass-rearing procedures. Thus, it is particularly important to understand whether male size can favor mating success. Read More

Distinct genetic architectures underlie divergent thorax, leg, and wing pigmentation between Drosophila elegans and D. gunungcola.

Heredity (Edinb) 2021 Sep 18. Epub 2021 Sep 18.

Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI, USA.

Pigmentation divergence between Drosophila species has emerged as a model trait for studying the genetic basis of phenotypic evolution, with genetic changes contributing to pigmentation differences often mapping to genes in the pigment synthesis pathway and their regulators. These studies of Drosophila pigmentation have tended to focus on pigmentation changes in one body part for a particular pair of species, but changes in pigmentation are often observed in multiple body parts between the same pair of species. The similarities and differences of genetic changes responsible for divergent pigmentation in different body parts of the same species thus remain largely unknown. Read More

Comparison of cervical motion restriction and interface pressure between two cervical collars.

Clin Biomech (Bristol, Avon) 2021 Sep 10;89:105482. Epub 2021 Sep 10.

MORE Foundation, 18444 N 25(th) Ave. Suite 110, Phoenix, AZ 85023, USA. Electronic address:

Background Cervical collar treatment is widespread amongst a broad range of ages and conditions. However, these devices are associated with a known correlation between collar usage and adverse effects such as pressure ulcers, infections, exacerbated spinal injury, and higher morbidity. The objective of this study was to determine if the ability of a newly developed DJO Procare XTEND 174 collar to restrict cervical spine motion was similar to that of the previously studied Össur Miami J collar and to determine if this was done while producing similar tissue interface pressures.

How and why do bees buzz? Implications for buzz pollination.

J Exp Bot 2021 Sep 19. Epub 2021 Sep 19.

Biological and Environmental Sciences, University of Stirling, Stirling, Scotland, United Kingdom.

Buzz pollination encompasses the evolutionary convergence of specialised floral morphologies and pollinator behaviour in which bees use vibrations (floral buzzes) to remove pollen. Floral buzzes are one of several types of vibrations produced by bees using their thoracic muscles. Here I review how bees can produce these different types of vibrations and discuss the implications of this mechanistic understanding for buzz pollination. Read More
