Effectiveness of a specific follow up program for the management of the mental components of post-intensive care syndrome and chronic pain after COVID-19: results from the PAIN-COVID randomized clinical trial

BACKGROUND

Critical COVID-19 survivors are at risk of developing Post-intensive Care Syndrome (PICS) and Chronic ICU-Related Pain (CIRP). We determined whether a specific care program improves the quality of life (QoL) of patients at risk of developing PICS and CIRP after COVID-19.

METHODS

The PAIN-COVID trial was a parallel-group, single-centre, single-blinded, randomized controlled trial. The intervention consisted of a follow up program, patient education on PICS and pain, and a psychological intervention based on Rehm's self-control model in patients with abnormal depression scores (≥8) in the Hospital Anxiety and Depression Scale (HADS) at the baseline visit. QoL was evaluated with the 5-level EQ 5D (EQ 5D 5 L), mood disorders with the HADS, post-traumatic stress disorder (PTSD) with the PCL-5 checklist, and pain with the Brief Pain Inventory short form, the Douleur Neuropathique 4 questionnaire, and the Pain Catastrophizing Scale. The primary outcome was to determine if the program was superior to standard-of-care on the EQ visual analogue scale (VAS) at 6 months after the baseline visit. The secondary outcomes were EQ VAS at 3 months, and EQ index, CIRP incidence and characteristics, and anxiety, depression, and PTSD at 3 and 6 months after baseline visits.

CONCLUSIONS

This program was not superior to standard care in improving QoL in critical COVID-19 survivors as measured by the EQ VAS. However, our data can help establish better strategies for the study and management of PICS and CIRP in this population.

Presymptomatic geographical distribution of ALS patients suggests the involvement of environmental factors in the disease pathogenesis

BACKGROUND

Given that the pathogenetic process of ALS begins many years prior to its clinical onset, examining patients' residential histories may offer insights on the disease risk factors. Here, we analyzed the spatial distribution of a large ALS cohort in the 50 years preceding the disease onset.

METHODS

Data from the PARALS register were used. A spatial cluster analysis was performed at the time of disease onset and at 1-year intervals up to 50 years prior to that.

RESULTS

A total of 1124 patients were included. The analysis revealed a higher-incidence cluster in a large area (435,000 inhabitants) west of Turin. From 9 to 2 years before their onset, 105 cases were expected and 150 were observed, resulting in a relative risk of 1.49 (P = 0.04). We also found a surprising high number of patients pairs (51) and trios (3) who lived in the same dwelling while not being related. Noticeably, these occurrences were not observed in large dwellings as we would have expected. The probability of this occurring in smaller buildings only by chance was very low (P = 0.01 and P = 0.04 for pairs and trios, respectively).

CONCLUSIONS

We identified a higher-incidence ALS cluster in the years preceding the disease onset. The cluster area being densely populated, many exposures could have contributed to the high incidence ALS cluster, while we could not find a shared exposure among the dwellings where multiple patients had lived. However, these findings support that exogenous factors are likely involved in the ALS pathogenesis.

Tobacco use in first-episode psychosis, a multinational EU-GEI study

BACKGROUND

Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis.

METHODS

The sample consisted of 1105 FEP patients and 1355 controls from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. We assessed substance use with the Tobacco and Alcohol Questionnaire and performed a series of regression analyses using case-control status, age of onset of psychosis, and diagnosis as outcomes and tobacco use and frequency of tobacco use as predictors. Analyses were adjusted for sociodemographic characteristics, alcohol, and cannabis use.

RESULTS

After controlling for cannabis use, FEP patients were 2.6 times more likely to use tobacco [p ⩽ 0.001; adjusted odds ratio (AOR) 2.6; 95% confidence interval (CI) [2.1-3.2]] and 1.7 times more likely to smoke 20 or more cigarettes a day (p = 0.003; AOR 1.7; 95% CI [1.2-2.4]) than controls. Tobacco use was associated with an earlier age at psychosis onset (β = -2.3; p ⩽ 0.001; 95% CI [-3.7 to -0.9]) and was 1.3 times more frequent in FEP patients with a diagnosis of schizophrenia than in other diagnoses of psychosis (AOR 1.3; 95% CI [1.0-1.8]); however, these results were no longer significant after controlling for cannabis use.

CONCLUSIONS

Tobacco and heavy-tobacco use are associated with increased odds of FEP. These findings further support the relevance of tobacco prevention in young populations.

[Arthroscopic biceps tenodesis with a «relaxed» technique.Clinical and radiological results of a prospective cohort]

INTRODUCTION

in the treatment the long head of the biceps tendon (LHBT) pathology, the «relaxed tenodesis» is an arthroscopic articular suprapectoral tenodesis that seeks to lower the tension on the LHBT, and therefore, theoretically avoid persistent pain.

OBJECTIVE

to assess clinical and radiological results of «relaxed» tenodesis in a prospective cohort of patient with work related illness.

MATERIAL AND METHODS

prospective cohort, 54 shoulders with «relaxed» tenodesis performed with an intra-articular interference screw by the same surgeon, from October 2014 to 2018, in a level 1 trauma center. Demographic, clinical, functional and radiologic results were analyzed. On 6 months follow-up, a sonographic and clinical assessment was performed.

RESULTS

mean age 49 ± 9, mean follow-up 16 ± 4 months. The main diagnosis was a rotator cuff tear in 79%, primary biceps pathology in 10% and other pathologies in 11%. At the end of follow-up, the cohort showed active anterior elevation 157.7 ± 22.7, external rotation 47 ± 16.6, median internal rotation T12, Constant Score 83 ± 12.05 points, subjective shoulder value 83 ± 12.97% and pain visual analogue scale 1.4 ± 1.7 points. One patient had a biceps tear and two had cosmetic arm asymmetry. On ultrasound 98% had the LHBT in situ and 10% had inflammatory changes on the bicipital groove. There were complications in 21% of the sample.

CONCLUSIONS

«relaxed biceps tenodesis» is a technique that shows good clinical, functional and sonographic results, with low failure rate.

Spontaneous subcapsular hepatic hematoma in pregnant patients

Spontaneous subcapsular hepatic hematoma (SSHH) with or without previous history of preeclampsia and/or HELLP syndrome represents a very rare pathological condition in pregnancy and postpartum, (1/45,000-1/225,000 pregnancies). Its importance for the anesthesiologist lays in its association with high morbidity and mortality for the mother (60-86%, 39%) and newborn (42%). After a high clinical suspicion, the certainty clinical diagnosis is settled by different imaging techniques. However, in most cases the diagnosis of SSHH is a casual intraoperative finding associated to a maternal or foetal compromise. Nowadays the obstetric and anaesthetic management of a SSHH is not standardized and depends on its integrity, hemodynamic stability and the gestational period when diagnosed. The possibility of an acute critic haemorrhage with necessity of massive transfusion, makes advisable to provide updated protocols for the treatment of obstetric hemorrhage, adapting them to the clinical peculiarities of these patients. After the acute phase, close attention should be kept on thromboembolic complications.

Effectiveness of thromboprophylaxis with low molecular weight heparin in critically ill patients with COVID-19. An observational prospective, multicenter study

INTRODUCTION

COVID-19 induces coagulopathy associated with an increase of thromboembolic events. Due to the lack of agreement on recommendations for thromboprophylactic management, the aim of this study was to study the dosages of LMWH used in critically ill COVID-19 patients assessing the effect on their outcome.

METHODS

We evaluated data of the Reg-COVID19. According to LMWH dose two groups were analyzed: prophylaxis and treatment. Primary outcome was the relationship of LMWH dosage with mortality. Secondary outcomes included the incidence of thrombotic and bleeding events, length of ICU stay, invasive mechanical ventilation, and thrombotic and inflammatory parameters.

RESULTS

Data of 720 patients were analyzed, 258 in the prophylaxis group and 462 in the treatment group. C Reactive Protein, invasive mechanical ventilation, tocilizumab and corticosteroid treatments were related with the choice of LMWH dose. Hemorrhagic events (66/720, 9.2%) and thrombotic complications (69/720, 9.6%) were similar in both groups (p = .819 and p = .265), as was the time course of the thrombotic events, earlier than hemorrhagic ones (9 [3-18] and 12 [6-19] days respectively). Mortality was lower in prophylaxis group (25.2% versus 35.1%), but once an inverse probability weighting model was applied, we found no effect of LMWH dose.

CONCLUSION

We found no benefit or harm with the administration of therapeutic or prophylactic LMWH dose in COVID19 critically ill patients. With a similar rate of hemorrhagic or thrombotic events, the LMWH dose had no influence on mortality. More studies are needed to determine the optimal thromboprophylaxis protocol for critically ill patients.

Maxillofacial Injuries in Padel Game

Background

Maxillofacial injuries are very frequent in the sports environment. Padel is a new sport of Mexican origin, very popular in Mexico, Spain, and Italy, but with a rapid spread in Europe and other continents.

Aims

The aim of this article is to report our experience of 16 patients with maxillofacial injuries that occurred during padel matches in 2021. All these injuries occurred due to the racket bouncing against the glass of the padel court. The bounce of the racquet is given either because the player was trying to hit the ball near the glass or by throwing the racket against the glass for an act of nervousness.

Methods

We carried out a literature review about sports traumas, and we calculated the possible force with which the racket, once bounced off the glass, hits the players' faces.

Results and Conclusions

The racket, bouncing off the glass wall, arrives with a specific force in the face of the player who threw the racket, being able to cause skin wounds, injuries, and fractures mainly at the level of the dentoalveolar junction.

Incidence of respiratory virus illness and hospitalizations in a Panama and El Salvador birth cohort, 2014-2018

Background

Respiratory viruses remain a key cause of early childhood illness, hospitalization, and death globally.The recent pandemic has rekindled interest in the control of respiratory viruses among paediatric populations. We estimate the burden of such viruses among children <2 years.

Methods

Enrolled neonates were followed until two years of age. Weekly active symptom monitoring for the development of acute respiratory illnesses (ARI) defined as cough, rhinorrhoea, difficulty breathing, asthenia, anorexia, irritability, or vomiting was conducted. When the child had ARI and fever, nasopharyngeal swabbing was performed, and samples were tested through singleplex RT-PCR. Incidence of respiratory viruses was calculated by dividing the number of laboratory-confirmed detections by the person-time accrued during weeks when that virus was detectable through national surveillance then corrected for under-ascertainment among untested children.

Findings

During December 2014-November 2017, 1567 enrolled neonates contributed 2,186.9 person-years (py). Six in ten (64·4%) children developed ARI (total 2493 episodes). Among children <2 years, incidence of respiratory syncytial virus (RSV)-associated ARI episodes (21·0, 95%CI 19·3-22·8, per 100py) and rhinovirus-associated (20·5, 95%CI 20·4-20·7) were similar and higher than parainfluenza 1-3-associated (14·2, 95%CI 12·2-16·1), human metapneumovirus-associated (9·2, 95%CI 7·7-10·8), influenza-associated (5·9, 95%CI 4·4-7·5), and adenovirus-associated ARI episodes (5·1, 95%CI 5·0-5·2). Children aged <3 months had the highest rates of RSV ARI (49·1, 95%CI 44·0-54·1 per 100py) followed by children aged 3-5 (25·1, 95%CI 20·1-30·0), 6-11 (17·6, 95%CI 13·2-21·9), and 12-23 months (11·9, 95%CI 10·8-12·9). One in ten children with RSV was referred to the hospital (2·5, 95%CI 2·1-2·8, per 100py).

Interpretation

Children frequently developed viral ARI and a substantive proportion required hospital care. Such findings suggest the importance of exploring the value of new interventions and increasing uptake of existing prevention measures to mitigate burden of epidemic-prone respiratory viruses.

Funding

The study was supported by the Centers for Disease Control and Prevention.

Does technology-based interventions in psychosis improved functioning and quality of life? A systematic review and meta-analysis

Introduction

Technology-based interventions (TBIs), including computer and Internet-based interventions, mobile interventions, health applications, social media interventions, and interventions using technological devices, could become a useful, effective, accessible, and cost-effective approach (Berry et al., 2016; Firth, 2016) to complement conventional interventions for psychosis

Objectives

to compare TBIs with conventional interventions for psychosis, focusing mainly on functioning and quality of life.

Methods

The systematic review preceding this work was based on 58 RCT of TBIs for psychosis. We selected the studies that analyzed functioning (N = 23) and quality of life (N = 15). We calculated the standardized mean change (SMC) and applied a three-level model because there were several effect sizes within the same study.

Results

There were significant differences between TBIs and conventional interventions for functioning (d = 0.25, SE = 0.09, z = 2.72, p = <.01), but not for quality of life (d = 0.14, SE = 0.08, z = 1.78, p = .076) in patients with psychosis.

Conclusions

On average, patients who received TBIs performed better in functioning, but not in quality of life. Functioning is impaired in patients with psychosis, so TBIs should be considered a complement and efficacious intervention, highlighting the power of these type of interventions in improving some outcomes.

Disclosure

No significant relationships.

Pilot study of an online intervention for young people with a first psychotic episode: Thinkapp

Introduction

Online interventions can be a complement to maintain the long-term effectiveness of psychosocial interventions in First Episode Psychosis (FEP) that have already demonstrated their efficacy in the short and medium term (Calvo et al., 2015).

Objectives

To test the effectiveness of a mobile app–based intervention (Thinkapp) to improve quality of life, functioning and symptomatology, and reduce days of admission and hospitalizations, in young people with FEP.

Methods

Fourteen patients with FEP, aged 14–30, recruited from Gregorio Marañón Hospital, Ramón y Cajal Hospital and AMAFE Foundation in Madrid (Spain) received treatment as usual plus a psychoeducational intervention through a mobile app. Changes in dependent variables over the course of the intervention were assessed by means of a battery of clinical tests at baseline, 3-month and 6-month follow-up using a Wilcoxon test.

Results

Of the fourteen patients included, 7 patients completed the 6-month follow-up and 8 completed the 3-month follow-up. There were significant differences in days of admission (p = 0.042) between baseline and 6-month follow-up. No significant results were observed in other clinical variables.

Conclusions

The study provides preliminary data potentially related to the reduction of days of admissions.

Disclosure

No significant relationships.

Anaesthetic management in neurosurgery in a patient with Eisenmenger syndrome and Down syndrome. A case report

Adults patients with congenital heart disease increasingly present for non cardiac surgery. The anesthetic management this type of patients in neurosurgery requires a meticulous surgical anesthetic planning. The need for urgent intervention, with the presence of a congenital heart disease evolved to Eisenmenger syndrome, associated to a difficult airway, is a challenge for the anesthesiologist. The use of dexmedetomidine may be a valid alternative. We present the case of a patient with Down syndrome, and Eisenmenger syndrome who underwent drainage of brain abscess from the emergency department and was subsequently scheduled for reintervention. We compare the different anesthetic techniques used in both procedures, analyzing the implications they had on the main physiopathological alterations presented by the patient.

Incidence of influenza and other respiratory viruses among pregnant women; a multi-country, multiyear cohort

OBJECTIVE

To quantify rates of influenza illness and assess value of influenza vaccination among pregnant women in Panama and El Salvador.

METHODS

Pregnant women were enrolled and followed each week in a prospective cohort study to identify acute respiratory infections (ARI). Nasopharyngeal swabs obtained from women with febrile ARI were tested by reverse-transcription polymerase chain reaction for influenza and other respiratory viruses.

RESULTS

We enrolled 2,556 women between October 2014-April 2017. Sixteen percent developed at least one ARI; 59 had two ARI, and five had three ARI for a total of 463 ARI. Women in El Salvador and Panama contributed 297 person-years (py) and 293py, respectively, during influenza circulation. Twenty-one (11%) of 196 sampled women tested positive for influenza. Influenza incidence was 5.0/100py (4.3/100py in Panama and 5.7/100py in El Salvador). Only 13% of women in El Salvador and 43% in Panama had been vaccinated against influenza before influenza epidemics (p<0.0001).

CONCLUSIONS

One in six pregnant women developed ARI and more than one in ten ARI were attributable to vaccine-preventable influenza. While women were at risk of influenza, few had vaccinated before each epidemic. Such findings suggest the utility of evaluations to optimize vaccine timing and coverage.

Trifluridine/tipiracil in combination with oxaliplatin and either bevacizumab or nivolumab in metastatic colorectal cancer: a dose-expansion, phase I study

Background

In preclinical studies trifluridine/tipiracil (FTD/TPI) plus oxaliplatin (Industriestrasse, Holzkirchen, Germany) sensitised microsatellite stable (MSS) metastatic colorectal cancer (mCRC) to anti-programmed cell death protein-1; the addition of oxaliplatin or bevacizumab (F Hoffmann- la ROCHE AG, Kaiseraugst, Switzerland) enhanced the antitumour effects of FTD/TPI. This study aimed to investigate the safety and efficacy of FTD/TPI plus oxaliplatin and either bevacizumab or nivolumab (Uxbridge business Park, Uxbridge, United Kingdom) in patients with mCRC who had progressed after at least one prior line of treatment.

Patients and methods

In 14-day cycles, patients received FTD/TPI 35 mg/m² (twice daily, days 1-5) plus oxaliplatin 85 mg/m² (day 1), and, on day 1, either bevacizumab 5 mg/kg (cohort A) or nivolumab 3 mg/kg (cohort B). Patients in Cohort B had confirmed MSS status.

Results

In total, 54 patients were enrolled: 37 in cohort A and 17 in cohort B. Recruitment in cohort B was stopped early due to the low response rate (RR) observed at interim analyses of efficacy. The most common adverse events (AEs) in cohort A were neutropenia/decreased neutrophils (75.7%), nausea (59.5%), vomiting (40.5%), diarrhoea (37.8%), peripheral sensory neuropathy (37.8%), fatigue (35.1%) and decreased appetite (35.1%). In cohort B, the most common AEs were neutropenia/decreased neutrophils (70.6%), diarrhoea (58.8%), nausea (47.1%), vomiting (47.1%), fatigue (47.1%), asthenia (41.2%), paraesthesia (41.2%), thrombocytopenia/decreased platelets (35.3%) and decreased appetite (35.3%). Confirmed objective RR was 17.1% in cohort A and 7.1% in cohort B; the corresponding values for median progression-free survival in the two cohorts were 6.3 and 6.0 months.

Conclusion

FTD/TPI plus oxaliplatin and bevacizumab or nivolumab had an acceptable safety profile and demonstrated antitumour activity in previously treated patients with mCRC.

•

This study evaluated the safety and efficacy of FTD/TPI plus oxaliplatin and either bevacizumab or nivolumab in mCRC patients.

•

FTD/TPI plus oxaliplatin in combination with bevacizumab or nivolumab had an acceptable and manageable safety profile.

•

Antitumour activity was observed following treatment with FTD/TPI plus oxaliplatin and bevacizumab.

•

Despite a modest RR with the addition of nivolumab, survival data were promising in these poor-prognosis patients.

Lower cognitive scores among toddlers in birth cohorts with acute respiratory illnesses, fevers, and laboratory-confirmed influenza

BACKGROUND

We established cohorts to assess associations between viral influenza and cognitive development to inform the value proposition of vaccination.

METHODS

From 2014 through 2017, we called women seeking care at four prenatal clinics in Panama and El Salvador to identify acute respiratory illnesses (ARIs). Within 2 weeks of childbirth, mothers were asked to enroll their neonates in the cognitive development study. Staff obtained nasopharyngeal swabs from children with febrile ARIs for real-time reverse transcription polymerase chain reaction (rtPCR) detection of viral RNA. Toddlers were administered Bayley developmental tests at ages 12 and 18-24 months. We used multilevel linear regression to explore associations between Bayley scores, ARIs, fever, and laboratory-confirmed influenza, controlling for maternal respiratory or Zika illnesses, infant influenza vaccination, birth during influenza epidemics, and the number of children in households.

RESULTS

We enrolled 1567 neonates of which 68% (n = 1062) underwent developmental testing once and 40% (n = 623) twice. Children with previous ARIs scored an average of 3 points lower on their cognitive scores than children without ARIs (p = 0.001). Children with previous fevers scored an average of 2.1 points lower on their cognitive scores than afebrile children (p = 0.02). In the second year, children with previous laboratory-confirmed influenza scored 4 points lower on their cognitive scores than children without influenza (p = 0.04, after controlling for first Bayley cognitive scores).

CONCLUSIONS

ARIs and fever during infancy were associated with lower Bayley scores at 12 months, and laboratory-confirmed influenza was associated with lower cognitive scores at 24 months suggesting the potential value of vaccination to prevent non-respiratory complications of influenza.

[Comparative analysis of three models of reverse shoulder prosthesis based on the new angles of distalization and lateralization]

PURPOSE

Compare functional and radiological outcomes of three different designs of reverse shoulder arthroplasty according to distalization and lateralization shoulder angle, in heterogenic diagnostics (fracture, cuff arthropathy, fracture sequela and osteoarthritis).

MATERIAL AND METHODS

Prospective cohort of 33 patients of reverse shoulder arthroplasty (RSA) between December 2014 and July 2017 with a minimum one year of follow-up. We defined three groups, G: 10 patients with Grammont (155o, Medialized Glena), B: 9 patients with Bio-RSA (155º, lateralized bone glena) and A: 14 patients with Arrow (135o, lateralized metallic glena). We analyze demographic, clinical, functional and radiological outcomes (lateralization shoulder angle (LSA) and distalization shoulder angle (DSA)). For the statistical analysis, ANOVA, T-tests and linear regression tests were used, with a statistical significance of 5%.

RESULTS

The LSA was significantly higher in group A (98o A, 79o G, 80o B) (p < 0.05). In DSA, group B was significantly higher than A (52o B, 39o A) (p < 0.05) and not significant to G (48o G) (p = 0.06). There was no correlation of LSA and DSA with external rotation (p = 0.51) and active elevation (p = 0.41), respectively. There was no significant clinical (anterior elevation, external rotation, internal rotation) and functional outcomes (adjusted Constant score and subjective shoulder evaluation) differences between the different RSA models (p > 0.05).

CONCLUSIONS

The LSA was higher in the Arrow and the DSA was higher in Bio-RSA. We did not find Clinical - Radiological correlation in this heterogeneous series of patients.

Disseminated intravascular coagulation as a form of presentation of coronavirus-19 disease. Clinical case

The covid-19 disease (coronavirus disease 2019) is a novel disease causing a world pandemic. Its presentation varies from an asymptomatic infection to a pneumonia with acute respiratory distress syndrome. We present a case presenting initially as a covid-19 pneumonia together with a disseminated intravascular coagulopathy consisting of arterial and venous thrombosis in different locations and a shock requiring admission in the intensive care unit. The abnormal coagulation test in covid-19 patients have been described since the first cases observed in Wuhan, China, as well as an increased incidence of venous thrombosis. On the contrary, a higher incidence of arterial thrombosis has not been described in these patients. The unusual case we present could be a manifestation of this altered tests.

High D dimers and low global fibrinolysis coexist in COVID19 patients: what is going on in there?

BACKGROUD

COVID-19 coagulopathy linked to increased D-dimer levels has been associated with high mortality (Fei Z et al. in Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study. Lancet (London, England) 395(10229):1054-62, 2020). While D-dimer is accepted as a disseminated intravascular coagulation marker, rotational thromboelastometry (ROTEM) also detects fibrinolysis (Wright FL et al. in Fibrinolysis shutdown correlates to thromboembolic events in severe COVID-19 infection. J Am Coll Surg (2020). Available from https://pubmed.ncbi.nlm.nih.gov/32422349/ [cited 14 Jun 2020]; Schmitt FCF et al. in Acute fibrinolysis shutdown occurs early in septic shock and is associated with increased morbidity and mortality: results of an observational pilot study. Ann Intensive Care 9(1):19, 2019). We describe the ROTEM profile in severely ill COVID-19 patients and compare it with the standard laboratory coagulation test.

METHODS

Adult patients diagnosed with COVID-19 admitted to the ICU were prospectively enrolled after Ethics Committee approval (HCB/2020/0371). All patients received venous thromboembolism prophylaxis; those on therapeutic anticoagulation were excluded. The standard laboratory coagulation test and ROTEM were performed simultaneously at 24-48 h after ICU admission. Sequential organ failure assessment (SOFA), disseminated intravascular coagulation (DIC) and sepsis-induced coagulopathy (SIC) scores were calculated at sample collection.

RESULTS

Nineteen patients were included with median SOFA-score of 4 (2-6), DIC-score of 1 (0-3) and SIC-score of 1.8 (0.9). Median fibrinogen, D-dimer levels and platelet count were 6.2 (4.8-7.6 g/L), 1000 (600-4200 ng/ml) and 236 (136-364 10⁹/L), respectively. Clot firmness was above the normal range in the EXTEM and FIBTEM tests while clot lysis was decreased. There was no significant correlation between ROTEM or D-dimer parameters and the SOFA score.

CONCLUSION

In COVID-19 patients, the ROTEM pattern was characterized by a hypercoagulable state with decreased fibrinolytic capacity despite a paradoxical increase in D-dimer levels. We suggest that, in COVID-19 patients, the lungs could be the main source of D-dimer, while a systemic hypofibrinolytic state coexists. This hypothesis should be confirmed by future studies.

[Tendon transfers around the shoulder for patient with brachial plexus injury sequels]

Brachial plexus lesions can significantly affect patient function. The type of management will depend on the severity of the injury as well as the anatomical location. Tendon transfers around the shoulder have emerged as an effective treatment alternative, and therefore we should consider them when faced with patients who might require it. There are various transfer techniques, within which the most frequently used are upper trapezium, latissimus dorsi and lower trapezium transfers, each with its specific indications and objectives depending on the type of patient. These surgeries aim to decrease the pain resulting from the hypotonia and glenohumeral subluxation as well as improve the range of movement of the shoulder, getting the patient to take his hand to the plane that requires to perform his daily life activities. We will provide a description of some of the most commonly used shoulder tendon transfer techniques associated with a bibliographic review and a description of our experience with these surgeries.

First-line single-agent regorafenib in frail patients with metastatic colorectal cancer: a pilot phase II study of the Spanish Cooperative Group for the Treatment of Digestive Tumours (TTD)

BACKGROUND

Treatment of frail patients with advanced colorectal cancer (CRC) is controversial. This pilot phase II trial aimed to assess the efficacy and safety of regorafenib when administered in first-line to frail patients with advanced CRC.

METHODS

Frail patients without prior advanced colorectal cancer treatment were included in the study. Definition of frailty was defined per protocol based on dependency criteria, presence of chronic comorbid pathologies and/or geriatric features.

MAIN OBJECTIVE

to assess progression-free survival (PFS) rate at 6 months. Treatment consisted of 28-day cycles of orally administered regorafenib 160 mg/day (3 weeks followed by 1 week rest).

RESULTS

Forty-seven patients were included in the study. Median age was 81 years (range 63-89). Frailty criteria: dependency was observed in 26 patients (55%), comorbidities in 27 (57%) and geriatric features in 18 (38%). PFS rate at 6 months was 45% (95% confidence interval [CI] 30-60]. Median PFS was 5.6 months (95%CI 2.7-8.4). Median overall survival (OS) was 16 months (95%CI 7.8-24). Complete response, partial response and stable disease were observed in one, two and 21 patients respectively (objective response rate 6.4%; disease control rate 51%). Thirty-nine patients (83%) experienced grade 3-4 adverse events (AEs). The most common grade 3-4 AEs were hypertension (15 patients; 32%), asthenia (14; 30%), hypophosphatemia (6; 13%); diarrhea (4; 8%), hand-foot-skin reaction (4; 8%). There were two toxic deaths (4.2%) (grade 5 rectal bleeding and death not further specified). Dose reduction was required in 26 patients (55%) and dose-delays in 13 patients (28%).

CONCLUSIONS

The study did not meet the pre-specified boundary of 55% PFS rate at 6 months. Toxicity observed (83% patients experienced grade 3 and 4 AEs) preclude its current use in clinical practice on this setting. Disease control rate and overall survival results are interesting and might warrant further investigation to identify those who benefit from this approach.

Gray matter differences between affective and non-affective first episode psychosis: A review of Magnetic Resonance Imaging studies: Special Section on "Translational and Neuroscience Studies in Affective Disorders" Section Editor, Maria Nobile MD, PhD. This Section of JAD focuses on the relevance of translational and neuroscience studies in providing a better understanding of the neural basis of affective disorders. The main aim is to briefly summaries relevant research findings in clinical neuroscience with particular regards to specific innovative topics in mood and anxiety disorders

BACKGROUND

Non-affective and affective psychoses are very common mental disorders. However, their neurobiological underpinnings are still poorly understood. Therefore, the goal of the present review was to evaluate structural Magnetic Resonance Imaging (MRI) studies exploring brain deficits in both non-affective (NA-FEP) and affective first episode psychosis (A-FEP).

METHODS

A bibliographic search on PUBMED of all MRI studies exploring gray matter (GM) differences between NA-FEP and A-FEP was conducted.

RESULTS

Overall, the results from the available evidence showed that the two diagnostic groups share common GM alterations in fronto-temporal regions and anterior cingulate cortex. In contrast, unique GM deficits have also been observed, with reductions in amygdala for A-FEP and in hippocampus and insula for NA-FEP.

LIMITATIONS

Few small MRI studies with heterogeneous methodology.

CONCLUSIONS

Although the evidences are far to be conclusive, they suggest the presence of common and distinct pattern of GM alterations in NA-FEP and A-FEP. Future larger longitudinal studies are needed to further characterize specific neural biomarkers in homogenous NA-FEP and A-FEP samples.

783. Characterization of Non-tuberculous Mycobacteria Isolates in a National Mycobacterial Laboratory in Panama: 2012–2015

Background

Nontuberculous mycobacteria (NTM) are becoming more frequently isolated in microbiology laboratories. There is no standardized diagnosis, treatment, and/or monitoring of patients with NTM disease. We described the experience of the Panama National Mycobacterial Laboratory in isolating NTM in patients suspected to have active tuberculosis in Panama.

Methods

Data registries of the National TB Program Laboratory of Panama between 2012 and 2015 were reviewed. Demographic information, relevant history, sample source, and isolate identified for each specimen obtained at the time of specimen submission was extracted. Identification of mycobacterial species were made using culture and PCR. Data were exported to an Excel workbook and a descriptive analysis was performed using STATA.

Results

A total of 4,545 samples were received during this period. Of these, 288 (6.3%) were not processed. From the remaining 4,257 samples, 705 (16.5%) were negative, 2,783 (65.3%) were positive for M. tuberculosis, and 769 (18%) were confirmed NTM. NTM species identification was achieved in 715 (93%) using PCR. Median age was 55 years (0 – 92); 49.4% were male. The most frequent NTM isolate was M. avium complex in 172 (22.3%) samples, followed by M. fortuitum in 131 (17%). M. chelonae was isolated in 98 (12.7%) samples, M. gordonae in 50 (6.5%), M. scrofulaceum in 20 (2.6%), and M. triviale in 16 (2.0%). NTM isolation steadily rose over the study period with 490 (63.7%) of the samples being from 2015 and 465 (94.5%) of these typified by PCR. Specimens mainly originated from the Panama metropolitan area (88.2%) and were mostly sputum samples (70.8%).

Conclusion

Nontuberculous mycobacteria represented an important proportion of isolates among TB suspects in Panama. The implementation of more sensitive diagnostic techniques is increasing the recovery of NTM. Further evaluation of the clinical significance of these finding is required for appropriate guideline implementation.

Correlation between Apolipoprotein E genotype and brain metabolism in amyotrophic lateral sclerosis

BACKGROUND AND PURPOSE

The aim of the study was to evaluate the metabolic correlates of Apolipoprotein E (APOE) genotype in amyotrophic lateral sclerosis (ALS) and to investigate the role of ε2 as a risk factor for cognitive impairment.

METHODS

A total of 159 ALS cases underwent APOE and ALS-related genes analysis, neuropsychological assessment and cerebral ¹⁸ F-2-fluoro-2-deoxy-D-glucose positron emission tomography. The APOE genotype was regressed against whole brain metabolism as assessed by ¹⁸ F-2-fluoro-2-deoxy-D-glucose positron emission tomography, with age, sex, education, type of onset and C9orf72 status as covariates.

RESULTS

Brain metabolism was significantly positively correlated with APOE genotype from ε2/ε2 to ε3/ε4 in the left prefrontal [Brodmann area (BA) 10], orbitofrontal (BAs 11, 45, 47) and anterior cingulate (BA 32) cortices. There was a tendency to a relative hypometabolism going towards the ε2/ε2 extreme.

CONCLUSIONS

We found a highly significant, relatively lower metabolism in association with the ε2 allele in extra-motor areas typically affected in frontotemporal dementia (left prefrontal, orbitofrontal and anterior cingulate cortices), strengthening the finding of a role of ε2 as a risk factor for cognitive impairment in ALS. Our data suggested a link between cholesterol homeostasis and neurodegeneration.

Cardiovascular diseases may play a negative role in the prognosis of amyotrophic lateral sclerosis

BACKGROUND AND PURPOSE

Only a few studies have considered the role of comorbidities in the prognosis of amyotrophic lateral sclerosis (ALS) and have provided conflicting results.

METHODS

Our multicentre, retrospective study included patients diagnosed from 1 January 2009 to 31 December 2013 in 13 referral centres for ALS located in 10 Italian regions. Neurologists at these centres collected a detailed phenotypic profile and follow-up data until death in an electronic database. Comorbidities at diagnosis were recorded by main categories and single medical diagnosis, with the aim of investigating their role in ALS prognosis.

RESULTS

A total of 2354 incident cases were collected, with a median survival time from onset to death/tracheostomy of 43 months. According to univariate analysis, together with well-known clinical prognostic factors (age at onset, diagnostic delay, site of onset, phenotype, Revised El Escorial Criteria and body mass index at diagnosis), the presence of dementia, hypertension, heart disease, chronic obstructive pulmonary disease, haematological and psychiatric diseases was associated with worse survival. In multivariate analysis, age at onset, diagnostic delay, phenotypes, body mass index at diagnosis, Revised El Escorial Criteria, dementia, hypertension, heart diseases (atrial fibrillation and heart failure) and haematological diseases (disorders of thrombosis and haemostasis) were independent prognostic factors of survival in ALS.

CONCLUSIONS

Our large, multicentre study demonstrated that, together with the known clinical factors that are known to be prognostic for ALS survival, hypertension and heart diseases (i.e. atrial fibrillation and heart failure) as well as haematological diseases are independently associated with a shorter survival. Our findings suggest some mechanisms that are possibly involved in disease progression, giving new interesting clues that may be of value for clinical practice and ALS comorbidity management.
