RESUMEN
BACKGROUND: COVID-19 acute respiratory distress syndrome (ARDS) is often managed with mechanical ventilation (MV), requiring sedation and paralysis, with associated risk of complications. There is limited evidence on the use of high flow nasal cannula (HFNC). We hypothesized that management of COVID-19 ARDS without MV is feasible. METHODS: Included were all adult patients diagnosed with COVID-19 ARDS, with PaO

Background: Women researchers might experience obstacles in academic environments and might be underrepresented in the authorship of articles published in peer-reviewed journals. Material and Methods: This is a cross-sectional analysis of female-led RCTs describing all interventions reducing mortality in critically ill and perioperative patients from 1981 to December 31, 2020. We searched PubMed/MEDLINE and EMBASE with the keywords RCTs and mortality. The gender of the first author was extracted and descriptive analysis was performed including the year of publication, impact factor, country of the first author, and methodological aspects. Results: We analyzed 340 RCTs, of which 42 (12%) were led by female researchers. The presence of women increased from 8% (14/172) until 2010 up to 17% (28/168) in 2010 and beyond. The United States, the United Kingdom, and Brazil were the main countries of origin of female researchers. Women authors conducted mainly single-center and single-nation studies as compared to male authors. The median impact factor of the target journal was 6 (3-27) in women vs. 7 (3-28) in men, with a p-value of 0.67; Critical Care Medicine, JAMA, and The New England Journal of Medicine were the most frequent target journals for both women and men. Conclusion: In the last 40 years, only one out of eight RCTs had a woman as the first author but the presence of women increased up to 17% by 2010 and beyond. The impact factor of publication target journals was high and not different between genders.
RESUMEN
OBJECTIVES: Randomized clinical trials (RCTs) represent the highest level of scientific evidence. The aim of this review was to map and summarize the main characteristics and publication trends of RCTs with a statistically significant effect on mortality in critically ill and perioperative patients. DESIGN: A mapping review of RCTs published between January 1982 and January 2021. The authors searched PubMed/MEDLINE and EMBASE for RCTs reporting mortality data. A descriptive analysis was conducted, including general and methodologic information of all these RCTs with a statistically significant difference (p < 0.05) in mortality. MEASUREMENTS AND MAIN RESULTS: The authors identified 340 studies published in 115 journals from 42 countries. The most represented clinical areas were ventilatory support (n = 58, 17%) and hemodynamics (n = 56, 16%). A detrimental effect on survival was described in 47 (14%) RCTs. Denmark had the highest number of published trials per million inhabitants. A total of 40 (12%) RCTs were led by a female author. The intention-to-treat principle was applied overall in 60% of RCTs, though this percentage increased up to 75% when the study was published in journals with high impact factor. CONCLUSIONS: In the largest contemporary RCTs database of interventions significantly influencing mortality, the authors found an increase in scientific production. United States, China, France, Italy, and the United Kingdom contributed with 172 (51%) RCTs over 40 years. Only 20% of the studies were multinational collaborations, though this percentage increased over time. The presence of women as first authors was 1 out of 8 RCTs.

Survival has been considered the cornerstone for clinical outcome evaluation in critically ill patients admitted to intensive care unit (ICU). There is evidence that ICU survivors commonly show impairments in long-term outcomes such as quality of life (QoL) considering them as the most relevant ones. In the last years, the concept of patient-important outcomes has been introduced and increasingly reported in peer-reviewed publications. In the present systematic review, we evaluated how many randomized controlled trials (RCTs) were conducted on critically ill patients and reporting a benefit on survival reported also data on QoL. All RCTs investigating nonsurgical interventions that significantly reduced mortality in critically ill patients were searched on MEDLINE/PubMed, Scopus and Embase from inception until August 2021. In a second stage, for all the included studies, the outcome QoL was investigated. The primary outcome was to evaluate how many RCTs analyzing interventions reducing mortality reported also data on QoL. The secondary endpoint was to investigate if QoL resulted improved, worsened or not modified. Data on QoL were reported as evaluated outcome in 7 of the 239 studies (2.9%). The tools to evaluate QoL and QoL time points were heterogeneous. Four interventions showed a significant impact on QoL: Two interventions improved survival and QoL (pravastatin in subarachnoid hemorrhage, dexmedetomidine in elderly patients after noncardiac surgery), while two interventions reduced mortality but negatively influenced QoL (caloric restriction in patients with refeeding syndrome and systematic ICU admission in elderly patients). In conclusion, only a minority of RCTs in which an intervention demonstrated to affect mortality in critically ill patients reported also data on QoL. Future research in critical care should include patient-important outcomes like QoL besides mortality. Data on this topic should be collected in conformity with PROs statement and core outcome sets to guarantee quality and comparability of results.

BACKGROUND: Percutaneous dilation tracheostomy is an aerosol-generating procedure carrying a documented infectious risk during respiratory virus pandemics. For this reason, during the COVID-19 outbreak, surgical tracheostomy was preferred to the percutaneous one, despite the technique related complications increased risk. METHODS: We describe a new sequence for percutaneous dilation tracheostomy procedure that could be considered safe both for patients and healthcare personnel. A fiberscope was connected to a video unit to allow bronchoscopy. Guidewire positioning was performed as usual. While the established standard procedure continues with the creation of the stoma without any change in mechanical ventilation, we retracted the bronchoscope until immediately after the access valve in the mount tube, allowing normal ventilation. After 3 minutes of ventilation with 100% oxygen, mechanical ventilation was stopped without disconnecting the circuit. During apnea, the stoma was created by dilating the trachea and the tracheostomy cannula was inserted. Ventilation was then resumed. We evaluated the safeness of the procedure by recording any severe desaturation and by performing serological tests to all personnel. RESULTS: Thirty-six patients (38%) of 96 underwent tracheostomy; 22 (23%) percutaneous dilation tracheostomies with the new approach were performed without any desaturation. All personnel (150 operators) were evaluated for serological testing: 9 (6%) had positive serology but none of them had participated in tracheostomy procedures. CONCLUSION: This newly described percutaneous dilation tracheostomy technique was not related to severe desaturation events and we did not observe any positive serological test in health workers who performed the tracheostomies.

BACKGROUND: Endocrine Disrupting Chemicals (EDCs) are ubiquitous and may significantly contribute to environmental pollution and contamination in humans and wildlife. Ecological pollutants could interfere with bone homeostasis through different mechanisms, including hormonal imbalance, direct osteoblast toxicity, and enhancement of osteoclasts activity, leading to either osteopenia or osteoporosis. Among these chemicals, bisphenols, dioxins, polycyclic aromatic hydrocarbons, polychlorobiphenyls, poly- and perfluoroalkyl, phthalates, parabens, organotins, and cadmium may play a role in the bone disruption. METHODS: Authors searched PubMed/MEDLINE, ISI-web of knowledge, and Google scholar databases for medical subject headings terms and free-text words related to the classes mentioned above of chemicals and bone metabolism and remodeling for better clarifying and understanding the main mechanisms of bone disruption. RESULTS: Several EDCs act as xeno-estrogens. Considering that estrogens play a significant role in regulating bone remodeling, most of these chemicals generate hormonal imbalance with possible detrimental consequences on bone tissue structure and its mechanical and non-mechanical properties. DISCUSSION: Much evidence about bone disruptors was obtained from in vitro studies or animal models with equivocal results. Besides, a few data have been acquired from humans, and most of these data focused on the impact of EDCs on bone mineral density without considering their influence on long-term fracture risk. Moreover, humans may be exposed to a mixture of EDCs, and the final effect on bone metabolism might be attributable to either synergistic or antagonist effects. Age of first exposure, cumulative exposure over time, and the usually observed non-monotonic dose-response curve for EDCs should be considered as other essential variables influencing bone metabolism's final effect. CONCLUSION: Given these variables, observational studies are needed to analyze this issue for ecological purposes better and preserve bone health.

OBJECTIVE: To determine the relationship between the value of fibrinogen assessed by the FIBTEM clot amplitude at 10 minutes (A10 FIBTEM) measured on admission to the intensive care unit (ICU) and the amount of drainage output at 24 hours, to investigate whether the A10 FIBTEM predicts severe bleeding (SB), and to define A10 FIBTEM thresholds to prevent (trigger) and treat (target) severe bleeding by fibrinogen supplementation. METHODS: In a single centre, retrospective observational study, 166 patients underwent elective open thoraco-abdominal aortic aneurysm (TAAA) repair between March 2016 and January 2019. Exclusion criteria were emergency, congenital, or acquired coagulopathy, or administration of P2Y12 inhibitor antiplatelet agents in the five days before surgery. All patients were managed intra-operatively and post-operatively according to a rotational thromboelastometry driven transfusion protocol. The principal endpoint was a composite outcome, which included bleeding, large volume transfusion, and re-operation. RESULTS: FIBTEM clot amplitude after 10 minutes measured on ICU admission and post-operative bleeding at 24 hours showed an inverse linear relationship (R2 = .03; p = .026). Performance of A10 FIBTEM in predicting SB evaluated by Receiving Operating Curve analysis showed an area under the curve of 0.63 (95% CI 0.56 - 0.70; p = .026) with a best cutoff of 9 mm. An A10 FIBTEM of 3 mm was the cutoff associated with a positive predictive value of 50%, while an A10 FIBTEM of 9 mm showed a negative predictive value of 92%. On multivariable analysis, an A10 FIBTEM ≤ 3 mm remained independently associated with SB. CONCLUSION: The present investigation shows for the first time in a population undergoing open TAAA repair that an A10 FIBTEM ≤ 3mm on ICU admission is associated with post-operative severe bleeding. Trigger and target values for fibrinogen supplementation, based on A10 FIBTEM, have been provided. The transferability and reliability of these cutoff values require further study.

Objective: The use of angiotensin II in invasively ventilated patients with coronavirus disease 2019 (COVID-19) is controversial. Its effect on organ function is unknown. Design: Prospective observational study. Setting: Intensive care unit (ICU) of a tertiary academic hospital in Milan, Italy. Participants: Adult patients receiving mechanical ventilation due to COVID-19. Interventions: Use angiotensin II either as rescue vasopressor agent or as low dose vasopressor support. Main outcome measures: Patients treated before angiotensin II was available or treated in an adjacent COVID-19 ICU served as controls. For data analysis, we applied Bayesian modelling as appropriate. We assessed the effects of angiotensin II on organ function. Results: We compared 46 patients receiving angiotensin II therapy with 53 controls. Compared with controls, angiotensin II increased the mean arterial pressure (median difference, 9.05 mmHg; 95% CI, 1.87-16.22; P = 0.013) and the PaO2/FiO2 ratio (median difference, 23.17; 95% CI, 3.46-42.88; P = 0.021), and decreased the odds ratio (OR) of liver dysfunction (OR, 0.32; 95% CI, 0.09-0.94). However, angiotensin II had no effect on lactate, urinary output, serum creatinine, C-reactive protein, platelet count, or thromboembolic complications. In patients with abnormal baseline serum creatinine, Bayesian modelling showed that angiotensin II carried a 95.7% probability of reducing the use of renal replacement therapy (RRT). Conclusions: In ventilated patients with COVID-19, angiotensin II therapy increased blood pressure and PaO2/FiO2 ratios, decreased the OR of liver dysfunction, and appeared to decrease the risk of RRT use in patients with abnormal baseline serum creatinine. However, all of these findings are hypothesis-generating only. Trial registration:ClinicalTrials.gov NCT04318366.
RESUMEN
The interest in percutaneous high-tech cardiac procedures has increased in recent years together with its safety and efficacy. In fragile patients, procedural sedation and analgesia are used to perform most of the procedures. General anesthesia remains the technique of choice during the team learning curve and might be required in selected patients or in emergent situations. Despite the high costs of percutaneous high-tech cardiac procedures, the decrease in length of hospital stays, rate of intensive care admission and complications, balance the increase in devices costs. In fragile patients who undergo percutaneous high tech cardiac procedures, the primary role of the anesthesiologist is to prevent the need for postprocedural intensive care unit and complications rate. Starting from the experience of a large university third level hospital we identified the eight most commonly performed contemporary percutaneous high tech cardiac procedures (ventricular tachycardia and atrial fibrillation ablation, protected percutaneous coronary intervention, transcatheter aortic valve implantation, MitraClip® (Abbott Laboratories; Abbott Park, IL, USA), percutaneous patent foramen ovale closure, left atrial appendage closure, and dysfunctional lead extraction), discuss the role of procedural sedation and analgesia in this setting, and explore future perspectives.

At the end of 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak spread from China all around the world, causing thousands of deaths. In Italy, the hardest hit region was Lombardy, with the first reported case on 20 February 2020. San Raffaele Scientific Institute a large tertiary hospital and research centre in Milan, Italy was immediately involved in the management of the public health emergency. Since the beginning of the outbreak, the elective surgical activity of the hospital was rapidly reduced and large areas of the hospital were simultaneously reorganised to admit and assist patients with coronavirus disease 2019 (COVID-19). In addition, the hospital became the regional referral hub for cardiovascular emergencies in order to keep ensuring a high level of health care to non-COVID-19 patients in northern Italy. In a few days, a COVID-19 emergency department was created, improving the general ward capacity to a total number of 279 beds dedicated to patients with COVID-19. Moreover, the number of intensive care unit (ICU) beds was increased from 28 to 72 (54 of them dedicated to patients with COVID-19, and 18 to cardiology and cardiac surgery hub emergencies), both converting pre-existing areas and creating new high technology spaces. All the involved health care personnel were rapidly trained to use personal protection equipment and to manage this particular category of patients both in general wards and ICUs. Furthermore, besides clinical activities, continuously important research projects were carried out in order to find new strategies and more effective therapies to better face an unprecedented health emergency in Italy.
RESUMEN
BACKGROUND: The Sufentanil Sublingual Tablet System (SSTS) is a new, pre-programmed, noninvasive, handheld system for patient-controlled analgesia (PCA) which may allow a faster postoperative recovery compared with standard PCA. The efficacy of SSTS in controlling pain after open abdominal surgery has already been documented. However, to our knowledge SSTS has never been investigated in patients undergoing major surgery within an Enhanced Recovery After Surgery (ERAS) protocol. METHODS: This observational, retrospective analysis included consecutive patients undergoing elective major abdominal and gynecological surgery. All patients received the SSTS device once they were fully awake and had a good control of pain at the end of the surgery. We analyzed changes in pain intensity according to the numerical rating scale (NRS) throughout the treatment as well as its duration, the number of administrations, and possible related adverse events. Patients were also interviewed to assess their quality of sleep and overall satisfaction with the SSTS device. RESULTS: The study included 308 patients. Compared to the first SSTS administration, pain intensity decreased from a median NRS of 6 to 0 at day 3, for an overall reduction of 79%. Results were already statistically significant at postoperative day 1 (p<0.01). Adverse reactions were observed in 62 patients, with nausea being the most frequent (12%), and in 93% of patients SSTS was discontinued because it was considered no longer necessary. Patient satisfaction was high, with 89% of them judging the device as "easy" or "very easy" to use. CONCLUSIONS: Although the retrospective and observational nature of the study as well as the absence of a comparative group limits the strength of evidence, our results consider SSTS an effective and safe tool for the management of postoperative pain after major abdominal and gynecological surgery within an ERAS protocol.
RESUMEN
BACKGROUND: Hirsutism in females can be a source of considerable psychological distress and a threat to female identity. The aim of our study was to evaluate a possible relationship between facial, total body hair involvement and physical, mental and social well-being during 12 months of follow-up and treatment. Both objective and subjective methods of evaluating hirsutism were used: the Ferriman-Gallwey (FG) scoring method and the questionnaires General Health Questionnaire (GHQ)-12, Polycystic Ovary Syndrome Questionnaire (PCOSQ) and SF-12. METHODS: The total of 469 female patients (mean age 27.61±7.63 years) was enrolled in 27 Italian centers participating in this study. Higher total body score was correlated to significant emotional discomfort. The correlation between the FG total body score, the facial score and physical/mental health was found to be significant in all the patients assessed by SF-12 questionnaire. The ongoing reduction of GHQ-12 score was found for the facial FG score at the first follow-up (T0-T1 period) and at the second one (T0-T2). No relationship was found between T1 and T2. At both 6 (T1) and 12 months (T2) follow-up an increase of PCOSQ Score (psychological improvement) was accompanied by a concomitant reduction of the FG Score (reduction of hirsutism). Physical health assessed by SF-12 questionnaire does not change at both 6- and 12-month follow-up, but mental health decreased at both T1 and T2. RESULTS: The clinical improvement was achieved at 6 months regardless on treatment used and it was maintained for the next six-month follow-up. The clinical outcome could be assessed both by FG Score both through questionnaires administrated to each patient with hirsutism. CONCLUSIONS: For the evaluation of psychopathological discomfort the most appropriate questionnaire was GHQ-12, because of it major sensitivity to identify the psychological discomfort in the hirsutism.

PURPOSE: The aim of this study is to investigate in a population of adolescents living in Regione Campania, undergoing sun exposure at least 9 months per year the prevalence of severe deficiency (<20 ng/ml) or insufficiency (21-29 ng/ml) of 25-Hydroxyvitamin D (25(OH)D) levels and its relationship with individual body weight, use of smoking, and exercise performance. METHODS: From October 2012 to October 2013, 373 healthy subjects (153 girls, 223 boys 11-20 years) without chronic diseases were consecutively enrolled in a campaign to prevent metabolic, cardiovascular, and oncological diseases. 25(OH)D assay, BMI, and lifestyle habitudes (smoking and exercise indoor or outdoor) were assessed. RESULTS: In this population, median 25(OH) level was 25.0 ng/ml (95 %CI 23.8-25.2) without any difference between girls (25.0 (95 %CI 23.1-25.7)) and boys (24.3 (95 %CI 23.8-25.2)). Severe deficiency was found in 6 girls (0.02 %), while insufficiency was found in 296 patients (110 girls, 79.3 %). Normal levels were found in 71 patients (37 girls, 19 %). Vitamin D levels were significantly correlated with BMI (r = -0.429, p < 0.0001), smoking (r = -0.241; p < 0.0001), and exercise performance (r = 0.791; p < 0.0001). At the multistep regression analysis, Vitamin D levels were best predicted by exercise performance (t = 19.6, p < 0.0001), less smoking addiction (t = -4.97, p < 0.001), and lower BMI (t = -4.69, p < 0.0001). CONCLUSIONS: The current study demonstrates that Vitamin D levels are commonly unsatisfactory in adolescents. Lower levels were found in overweight or obese adolescent, smokers and with low or absence of physical activity outdoors.

Pregnancy is becoming a relatively common event in patients with pituitary tumors (PT), due to the increasing availability of medical treatments, which control pituitary diseases associated with the development of PT. However, the presence of PT and its treatment may be a disturbing factor for pregnancy, and pregnancy significantly influences the course and the management of PT. This review summarizes the knowledge about the management of PT during pregnancy and the occurrence of pregnancy in patients with pre-existent PT, focusing on secreting PT characterized by hormonal excess and on clinically non-functioning PT often associated to hormone deficiency, which configure the hypopituitaric syndrome.

OBJECTIVE: Acromegalic patients have an increased risk of mortality. The objective of this study was to compare the effect of different therapies for acromegaly on mortality. DESIGN AND METHODS: The mortality rate of 438 consecutive acromegalic patients was compared with that of the general population using the standardized mortality ratio (SMR); the effect of different therapies on survival was evaluated using Cox regression analysis. RESULTS: Twenty patients (4.5%) died between 1999 and 2009. Age- and sex-adjusted SMR was 0.70 (95% CI 0.43-1.08). The Cox regression analysis revealed that, in the whole population, both general risk factors (age and physical status) and specific factors for acromegaly (macroadenoma, hypopituitarism and uncontrolled disease) were associated with death. The most compromised patients at diagnosis had a higher mortality rate (P=0.001), which also occurred in patients with controlled acromegaly. Death occurred in 2.4% (adenomectomy), 2.6% (adenomectomy followed by somatostatin analogue (SSA) therapy) and 11.4% (SSA therapy as the primary therapy) of the patients. The risk of death was higher in patients receiving SSA therapy as the primary therapy (hazard ratio (HR) 5.52, 95% CI 1.06-28.77, P=0.043) than in all patients submitted to adenomectomy; however, a higher risk of death occurred only in diabetic patients treated with SSAs alone (HR 21.94, 95% CI 1.56-309.04, P=0.022). Radiotherapy was associated with an increased risk of mortality, which occurred in patients with the more locally advanced disease. CONCLUSIONS: Therapies for acromegaly and comorbidities have lowered the risk of mortality to the level of the general population; the effect of SSA therapy alone or that following pituitary adenomectomy was comparable to that of curative neurosurgery on survival in non-diabetic patients; on the contrary, SSA therapy as the primary therapy may be less effective than adenomectomy in reducing mortality rate in diabetic patients.

CONTEXT: Usefulness of circulating Chromogranin A (CgA) for the diagnosis of neuroendocrine tumors (NEN) is controversial. The aim of the present study was to assess the actual role of this marker as diagnostic tool. METHODS: Serum blood samples were obtained from 42 subjects affected with NEN, 120 subjects affected with non-endocrine neoplasias (non-NEN) and 100 non-neoplastic subjects affected with benign nodular goitre (NNG). Determination of CgA was performed by means of immunoradiometric assay. RESULTS: The CgA levels among NEN-patients were not significantly different from NNG and non-NEN subjects. The Receiver operating characteristic (ROC) curves analysis failed to identify a feasible cut-off value for the differential diagnosis between NEN and the other conditions. CONCLUSION: Serum CgA is not helpful for the first-line diagnosis of NEN.
