First we would like to comment on the role of frailty in assessment of burns. The elderly population is of special interest in all fields of clinical medicine, owing to the ageing of the world population [1]. The definition of frailty is relatively concise. It is defined as a state of depletion of the homeostatic reserve due to changes accumulated during lifetime. In consequence, resolution of stressor sequelae is impaired [2]. Although the definition is straightforward, the methods of its application and quantification of frailty are not unequivocally accepted [3]. Ward and Romanowski in their papers used the Clinical Frailty Scale [4]. Other developed scales, to mention only a few, are the general Korean Frailty Index for Primary Care [5], the Modified Frailty Index 5 (mFI-5) [6], the more specialized Emergency General Surgery Frailty Index [7], and the Burn Frailty Index [8]. Some of them were evaluated in surgery patients, and the Burn Frailty Index was developed by Maxwell specifically to be used in burn patients [8]. A study comparing the usefulness of various frailty scales in a burn ward would be a welcome addition to the discussion about burn outcomes. We would also like to address one more aspect of frailty. Generally, the term is connected with the elderly population, i.e. more than 65 years old. This is based on the fact that one's frailty is a sum of deficits accumulated over the whole lifetime [9]. Yet even in younger age groups various tools used to assess frailty show a relatively high percentage of frail people [10, 11]. Research including patients undergoing orthopaedic surgery has proven that frailty assessment is a viable choice to predict complications even in younger groups [12]. Therefore we assume that frailty indexes will gradually become tools used also in younger groups of patients.Restoring partial flow of oxygenated blood is a fundamental goal of cardiopulmonary resuscitation. The ideal devices used for this purpose should have features such as low incidence of complications, high survival rate, rapid control of the airway, and adequate ventilation. Besides limiting the frequency and duration of interruptions in chest compressions, they can improve the survival and clinical outcomes of return of spontaneous circulation during cardiopulmonary resuscitation. The overall rates of survival from out-of-hospital cardiac arrest have improved dramatically in recent years. However, optimal airway management during out-of-hospital cardiac arrest is a controversial issue. The proposed standard of care, i.e. endotracheal intubation, may have paradoxical adverse effects on intended outcomes by interrupting cardiopulmonary resuscitation and by reduction of coronary and cerebral perfusion pressure during resuscitation. check details The aim of this narrative review is to provide health care providers with an overview of relevant studies in the area, with a focus on alternative advanced airway techniques.

Severe vitamin D deficiency in critically ill patients is linked to mortality. There are no scientific data regarding vitamin D status in critically ill patients undergoing continuous renal replacement therapies.

We aimed to measure vitamin D serum levels in critically ill patients with multi-organ failure undergoing continuous renal replacement therapies. Vitamin D serum measurements in 12-hour time intervals were performed in 20 patients undergoing continuous renal replacement therapies through continuous veno-venous haemodiafiltration (the study group). The results were then compared with the historical control group (20 patients without renal replacement therapy).

In the control group the median vitamin D level initially decreased, then stabilised around the fourth and fifth measurement, after which it appeared to increase unevenly. In the study group the median vitamin D level decreased considerably, and then stabilised around the third measurement. Although the differences between groups gradually increased for the last three measurements, there was insufficient evidence to indicate that they were statistically significant (P > 0.05). Significant correlations were found between the time of measurement and the level of vitamin D in the study (R = -0.31, P = 0.0002) and control groups (R = -0.18, P = 0.0341).

Vitamin D serum levels decline rapidly during the course of critical illness in patients undergoing continuous renal replacement therapies. No statistically significant differences in the levels of vitamin D between the study and control groups were found.

A high-flow nasal cannula (HFNC) is an alternative device for oxygena-tion, which improves gas exchange and reduces the work of breathing. Postextubation respiratory failure causes increased morbidity and mortality. HFNC has been widely employed during the COVID-19 pandemic. The purpose of this paper is to report a single-centre experience on the effectiveness and safety of HFNC in weaning COVID-19 patients.

Nine patients showed severe acute respiratory failure and interstitial pneumonia due to SARS-CoV-2. After mechanical ventilation (5 Helmet CPAP, 4 invasive mechanical ventilation), they were de-escalated to HFNC. Settings were 34-37°C, flow from 50 to 60 L min-1. FiO2 was set to achieve appropriate SpO2.

Nine patients (4 females; age 63 ± 13.27 years; BMI 27.2 ± 4.27) showed a baseline PaO2/FiO2 of 109 ± 45 mm Hg. After a long course of ventilation all patients improved (PaO2/FiO2 336 ± 72 mm Hg). Immediately after initiation of HFNC (2 hours), PaO2/FiO2 was 254 ± 69.3 mm Hg. Mean ROX index at two hours was 11.17 (range 7.38-14.4). It was consistent with low risk of HFNC failure. No difference was observed on lactate. After 48 hours of HFNC oxygen therapy (day 3), mean PaO2/FiO2 increased to 396 ± 83.5 mm Hg. All patients recovered from respiratory failure after 7 ± 4.1 days.

HFNC might be helpful in weaning COVID-19 respiratory failure. Effectiveness and comfort should be assessed between 2 and 48 hours. Clinical outcomes, oxygenation, and ROX index should be considered, to rule out the need for intubation. Further evidence is required for firm conclusions.

Significant technological improvements have contributed to the increasing adoption of US for musculoskeletal assessments, as artificial intelligence (AI)-based computer-aided detection and computer-aided diagnosis are being utilized to improve the quality, efficiency, and cost of US imaging. This review provides an overview of classical machine learning techniques and modern deep learning approaches for musculoskeletal US, with a focus on the key categories of detection and diagnosis of musculoskeletal disorders, predictive analysis with classification and regression, and automated image segmentation. Moreover, we outline challenges and a range of opportunities for AI in musculoskeletal US practice.Deep learning is one of the most popular artificial intelligence techniques used in the medical field. Although it is at an early stage compared to deep learning analyses of computed tomography or magnetic resonance imaging, studies applying deep learning to ultrasound imaging have been actively conducted. This review analyzes recent studies that applied deep learning to ultrasound imaging of various abdominal organs and explains the challenges encountered in these applications.

Regional lymph node (LN) dissection is a standard surgical procedure for endometrial cancer, but there is currently no clear consensus on its therapeutic significance. We aimed to determine the impact of regional LN dissection on the outcome of endometrial cancer.

Study subjects comprised 36,813 patients who were registered in the gynecological tumor registry of the Japan Society of Obstetrics and Gynecology, had undergone initial surgery for endometrial cancer between 2004 and 2011, and whose clinicopathological factors and prognosis were appropriate for our investigation. The following clinicopathological factors were obtained from the registry age, surgical stage classification, Union for International Cancer Control tumor, node, metastasis classification, histological type, histological differentiation, presence or absence of LN dissection, and postoperative treatment. We retrospectively analyzed the clinicopathological factors and therapeutic outcomes for patients with endometrial cancer.

Analysis of all subjects showed that the group that underwent LN dissection had a significantly better overall survival than the group that did not undergo dissection. Analysis based on stage showed similar results across groups, except for stage Ia. Analysis based on stage and histological type showed similar results across groups, except for stage Ia endometrial carcinoma G1 or Ia G2. Multivariate analysis of prognostic factors indicated that LN dissection is an independent prognostic factor and that it has a greater impact on prognosis than adjuvant chemotherapy.

Despite the limitations of a retrospective study with some biases, the results suggest that LN dissection in endometrial cancer has a prognostic effect.

Ledipasvir/sofosbuvir (LDV/SOF) shows high efficacy and safety in patients with genotype 1-hepatitis C virus (HCV). We aimed to investigate the efficacy and safety of LDV/SOF in real-world Mongolian patients.

Between 2015 to 2019, 23 (0.5%) and 5,005 patients (99.5%) with genotype 1a and 1b HCV, respectively, were treated with a fixed-dose tablet containing 90 mg ledipasvir and 400 mg sofosbuvir for 12 weeks, and 81 patients (1.6%) with previous experience of interferon (IFN)-based treatment received additional 1,000 mg ribavirin. HCV RNA was measured at 4, 12, and 24 weeks after the first dose to determine rapid virologic response, end of treatment response (ETR), and sustained virologic response at 12 weeks after end of treatment (SVR12).

Most patients (n=5,008; 99.6%) achieved ETR and SVR12 without virologic relapse. Patients with genotype 1a showed low rates of ETR and SVR12 in only 16 patients (69.6%). There was no significant difference in SVR12 rate between patients regardless of IFN experience (n=81; 1.
