Valued technical and non-technical skills among disaster responders: a cross sectional study of disaster responders involved in the earthquake in Türkiye and Syria January 2023.

Introduction: Disaster responders are an important part of disaster response. However, despite large efforts to train disaster responders, there is a limited scientific knowledge regarding which competences and skills such responders value and lack during a real mission. The aim of this study was to investigate used and needed skills among disaster responders responding to the earthquake in Türkiye and Syria 2023 METHODS: A cross-sectional study using a non-randomized sample was conducted, collected between March and July, 2023.

Trimodal wireless intramuscular device detects muscle pressure, flow, and oxygenation changes in porcine model of lower extremity compartment syndrome.

Purpose: Compartment syndrome remains difficult to diagnose early in its clinical course. Pressure transducer catheters have been used to directly measure intracompartmental pressure (ICP), but this method is unreliable, with a false positive rate of 35%. We have previously used intramuscular near infrared spectroscopy to detect changes in tissue oxygen saturation (StO) in response to increasing ICP using a novel implantable probe.

Skin Pigmentation Affects ViOptix T.Ox Performance in Variably Pigmented Preclinical Model of Flap Ischemia and Congestion.

Background: Free flap monitoring is more difficult in patients with dark skin because ischemia and congestion can be masked by pigmentation. For this reason, adjunct methods such as cutaneous near-infrared spectroscopy are of elevated importance in patients with highly pigmented skin. The purpose of this experiment is to determine if ViOpitx T.

A retrospective analysis of mission reports in the national Swedish Police Registry on mountain rescue 2018-2022: here be snowmobiles.

Background: Increasing mountain activity and decreasing participant preparedness, as well as climate change, suggest needs to tailor mountain rescue. In Sweden, previous medical research of these services are lacking. The aim of the study is to describe Swedish mountain rescue missions as a basis for future studies, public education, resource allocation, and rescuer training.

Non-technical skills needed by medical disaster responders- a scoping review.

Background: There is no universal agreement on what competence in disaster medicine is, nor what competences and personal attributes add value for disaster responders. Some studies suggest that disaster responders need not only technical skills but also non-technical skills. Consensus of which non-technical skills are needed and how training for these can be provided is lacking, and little is known about how to apply knowledge of non-technical skills in the recruitment of disaster responders.

Nerve Transfer After Cervical Spinal Cord Injury: Who Has a "Time Sensitive" Injury Based on Electrodiagnostic Findings?

Objective: To use the ulnar compound muscle action potential (CMAP) to abductor digiti minimi (ADM) to identify the proportion of individuals with cervical spinal cord injury (SCI) who have lower motor neuron (LMN) abnormalities involving the C8-T1 spinal nerve roots, within 3-6 months, and thus may influence the response to nerve transfer surgery.

Design: Retrospective analysis of prospectively collected data. Data were analyzed from European Multicenter Study About SCI database.

Assessing an Online Patient Decision Aid about Upper Extremity Reconstructive Surgery for Cervical Spinal Cord Injury: Pilot Testing Knowledge, Decisional Conflict, and Acceptability.

Unlabelled: While nerve and tendon transfer surgery can restore upper extremity function and independence after midcervical spinal cord injury, few individuals (∼14%) undergo surgery. There is limited information regarding these complex and time-sensitive treatment options. Patient decision aids (PtDAs) convey complex health information and help individuals make informed, preference-consistent choices.

Significance and Interrelationship of the Symptoms Listed in the DSM Criteria for Premenstrual Dysphoric Disorder.

Objective: While premenstrual dysphoric disorder (PMDD) as defined in DSM has become an established diagnosis, and a formal indication for drug treatment, the relative impact of the disparate symptoms named in the criteria, and to what extent they indeed constitute parts of one syndrome, remains insufficiently clarified. We have therefore explored the frequency, impact, and inter-relationship of different PMDD symptoms.

Method: Using a web survey, 10,457 Swedish women of fertile age were asked to retrospectively assess if they experience reduced functioning due to symptoms clearly associated with the premenstrual phase.

Pregnancy Outcomes in Women Screened for Tuberculosis Infection in Swedish Antenatal Care.

Background: Tuberculosis (TB) disease has been associated with pregnancy complications. However, the potential impact of TB infection (TBI) on pregnancy outcome is unknown. To investigate this, we conducted a register-based study in immigrant women screened with QuantiFERON assays for TBI in antenatal care in Sweden.

Point-of-Care Tissue Oxygenation Assessment with SnapshotNIR for Alloplastic and Autologous Breast Reconstruction.

Unlabelled: In breast reconstruction, mastectomy and free flaps are susceptible to vascular compromise and tissue necrosis. The SnapshotNIR device (Kent Imaging, Calgary, AB, Canada) utilizes near-infrared spectroscopy to measure tissue oxygen saturation (StO) and hemoglobin concentration. Here, we report on the use of this device for StO monitoring among patients receiving alloplastic or autologous breast reconstruction.

Successful living donor liver transplantation in a patient with hemophilia A and factor VIII inhibitor: A case report with perioperative recommendations.

Liver transplantation in patients with end-stage liver disease and coexisting hemophilia A has been described. Controversy exists over perioperative management of patients with factor VIII inhibitor predisposing patients to hemorrhage. We describe the case of a 58-year-old man with a history of hemophilia A and factor VIII inhibitor, eradicated with rituximab prior to living donor liver transplantation without recurrence of inhibitor.

Compound Effect of Hypoalbuminemia and Obesity on Complications after Autologous Breast Reconstruction.

Background: Obesity is among the risk factors identified that impair postoperative wound healing. Recently, malnutrition and sarcopenia have also been found to correlate with poor surgical outcomes; however, the effect of malnutrition in the setting of obesity is understudied, particularly in reconstructive surgery. The authors examine the American College of Surgeons National Surgery Quality Improvement Program database to determine the impact of obesity plus hypoalbuminemia on complications after autologous breast reconstruction.

Intramuscular Microvascular Flow Sensing for Flap Monitoring in a Porcine Model of Arterial and Venous Occlusion.

Background:  Commercially available near infrared spectroscopy devices for continuous free flap tissue oxygenation (StO) monitoring can only be used on flaps with a cutaneous component. Additionally, differences in skin quality and pigmentation may alter StO measurements. Here, we present a novel implantable heat convection probe that measures microvascular blood flow for peripheral monitoring of free flaps, and is not subject to the same issues that limit the clinical utility of near-infrared spectroscopy.

Wireless implantable optical probe for continuous monitoring of oxygen saturation in flaps and organ grafts.

Continuous, real-time monitoring of perfusion after microsurgical free tissue transfer or solid organ allotransplantation procedures can facilitate early diagnosis of and intervention for anastomotic thrombosis. Current technologies including Doppler systems, cutaneous O-sensing probes, and fluorine magnetic resonance imaging methods are limited by their intermittent measurements, requirements for skilled personnel, indirect interfaces, and/or their tethered connections. This paper reports a wireless, miniaturized, minimally invasive near-infrared spectroscopic system designed for uninterrupted monitoring of local-tissue oxygenation.

Percutaneously introduced wireless intramuscular near-infrared spectroscopy device detects muscle oxygenation changes in porcine model of lower extremity compartment syndrome.

Serial examination and direct measurement of intracompartmental pressure (ICP) are suboptimal strategies for the detection of acute compartment syndrome (CS) because they are operator-dependent and yield information that only indirectly reflects intracompartmental muscle perfusion. As a result, instances of unnecessary fasciotomy and unrecognized CS are relatively common. Recently, near-infrared spectroscopy (NIRS)-based systems for compartment monitoring have generated interest as an adjunct tool.

Facilitators and Barriers for Effective Staff Work in Swedish National Governmental Crisis Response to the COVID-19 Pandemic.

Objectives: The coronavirus disease (COVID-19) crisis response in Sweden was managed foremost by a collaboration of several national agencies. Normally, their strategical and operational collaboration is limited, but the pandemic required new and unfamiliar collaborations. This study aimed to clarify the facilitators and barriers of perceived effective staff work within and between 4 national agencies.

Implantable, wireless, self-fixing thermal sensors for continuous measurements of microvascular blood flow in flaps and organ grafts.

Vascular pedicle thrombosis after free flap transfer or solid organ transplantation surgeries can lead to flap necrosis, organ loss requiring re-transplantation, or even death. Although implantable flow sensors can provide early warning of malperfusion and facilitate operative salvage, measurements performed with existing technologies often depend on extrinsic conditions such as mounting methods and environmental fluctuations. Furthermore, the mechanisms for fixing such probes to vascular or skeletal structures may disrupt the normal blood flow or cause unnecessary tissue damage.

The History and Innovations of Blood Vessel Anastomosis.

Surgical technique and technology frequently coevolve. The brief history of blood vessel anastomosis is full of famous names. While the techniques pioneered by these surgeons have been well described, the technology that facilitated their advancements and their inventors deserve recognition.

National Outcomes of Prophylactic Lymphovenous Bypass during Axillary Lymph Node Dissection.

Background:  Breast cancer treatment, including axillary lymph node excision, radiation, and chemotherapy, can cause upper extremity lymphedema, increasing morbidity and health care costs. Institutions increasingly perform prophylactic lymphovenous bypass (LVB) at the time of axillary lymph node dissection (ALND) to reduce the risk of lymphedema but reports of complications are lacking. We examine records from the American College of Surgeons (ACS) National Surgery Quality Improvement Program (NSQIP) database to examine the safety of these procedures.

Intramuscular Near-Infrared Spectroscopy for Muscle Flap Monitoring in a Porcine Model.

Background:  Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are limited to flaps which carry a cutaneous paddle. As such, this useful and reliable technology has not previously been applicable to muscle-only free flaps where other modalities with substantial limitations continue to be utilized.

Methods:  We present the first NIRS probe which allows continuous monitoring of local tissue oxygen saturation (StO) directly within the substance of muscle tissue.

A Wireless Near-Infrared Spectroscopy Device for Flap Monitoring: Proof of Concept in a Porcine Musculocutaneous Flap Model.

Background:  Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are highly sensitive for detecting malperfusion. However, the clinical utility and user experience are limited by the wired connection between the sensor and bedside console. This wire leads to instability of the flap-sensor interface and may cause false alarms.

Mobilisation of emergency services for chemical incidents in Sweden - a multi-agency focus group study.

Background: In chemical incidents, infrequent but potentially disastrous, the World Health Organization calls for inter-organizational coordination of actors involved. Multi-organizational studies of chemical response capacities are scarce.
